vispy.scene.node module#
class vispy.scene.node.Node(parent=None, name=None, transforms=None)#
Bases: object
Base class representing an object in a scene.
A group of nodes connected through parent-child relationships define a scenegraph. Nodes may have any number of children.
Each Node defines a transform property, which describes the position, orientation, scale, etc. of the Node relative to its parent. The Node's children inherit this property, and then further apply their own transformations on top of that.
With the transform property, each Node implicitly defines a "local" coordinate system, and the Nodes and edges in the scenegraph can be thought of as coordinate systems connected by transformation functions.
Parameters:
parentNode
The parent of the Node.
namestr
The name used to identify the node.
transformsinstance of TransformSystem | None
The associated transforms.
property canvas#
The canvas in which this node's scenegraph is being drawn.
property children#
A copy of the list of children of this node. Do not add items to this list, but use x.parent = y instead.
property clip_children#
Boolean indicating whether children of this node will inherit its clipper.
property clipper#
A visual filter that can be used to clip visuals to the boundaries of this node.
common_parent(node)#
Return the common parent of two entities
If the entities have no common parent, return None.
Parameters:
nodeinstance of Node
The other node.
Returns:
parentinstance of Node | None
The parent.
describe_tree(with_transform=False)#
Create tree diagram of children
Parameters:
with_transformbool
If true, add information about node transform types.
Returns:
treestr
The tree diagram.
property document#
The document is an optional property that is an node representing the coordinate system from which this node should make physical measurements such as px, mm, pt, in, etc. This coordinate system should be used when determining line widths, font sizes, and any other lengths specified in physical units.
The default is None; in this case, a default document is used during drawing (usually this is supplied by the SceneCanvas).
property document_node#
The node to be used as the document coordinate system.
By default, the document node is self.root_node.
is_child(node)#
Check if a node is a child of the current node
Parameters:
nodeinstance of Node
The potential child.
Returns:
childbool
Whether or not the node is a child.
property name#
node_path(node)#
Return two lists describing the path from this node to another
Parameters:
nodeinstance of Node
The other node.
Returns:
p1list
First path (see below).
p2list
Second path (see below).
Notes
The first list starts with this node and ends with the common parent between the endpoint nodes. The second list contains the remainder of the path from the common parent to the specified ending node.
For example, consider the following scenegraph:
A --- B --- C --- D
 --- E --- F
Calling D.node_path(F) will return:
([D, C, B], [E, F])
node_path_to_child(node)#
Return a list describing the path from this node to a child node
If node is not a (grand)child of this node, then raise RuntimeError.
Parameters:
nodeinstance of Node
The child node.
Returns:
pathlist | None
The path.
node_path_transforms(node)#
Return the list of transforms along the path to another node.
The transforms are listed in reverse order, such that the last transform should be applied first when mapping from this node to the other.
Parameters:
nodeinstance of Node
The other node.
Returns:
transformslist
A list of Transform instances.
node_transform(node)#
Return the transform that maps from the coordinate system of self to the local coordinate system of node.
Note that there must be a _single_ path in the scenegraph that connects the two entities; otherwise an exception will be raised.
Parameters:
nodeinstance of Node
The other node.
Returns:
transforminstance of ChainTransform
The transform.
on_parent_change(event)#
Parent change event handler
Parameters:
eventinstance of Event
The event.
property opacity#
property order#
A value used to determine the order in which nodes are drawn.
Greater values are drawn later. Children are always drawn after their parent.
property parent#
The parent of this node in the scenegraph.
Nodes inherit coordinate transformations and some filters (opacity and clipping by default) from their parents. Setting this property assigns a new parent, changing the topology of the scenegraph.
May be set to None to remove this node (and its children) from a scenegraph.
parent_chain()#
Return the list of parents starting from this node. The chain ends at the first node with no parents.
property picking#
Boolean that determines whether this node (and its children) are drawn in picking mode.
property root_node#
property scene_node#
The first ancestor of this node that is a SubScene instance, or self if no such node exists.
set_transform(type_, *args, **kwargs)#
Create a new transform of type and assign it to this node.
All extra arguments are used in the construction of the transform.
Parameters:
type_str
The transform type.
*argstuple
Arguments.
**kwargsdict
Keywoard arguments.
property transform#
The transform that maps the local coordinate frame to the coordinate frame of the parent.
update()#
Emit an event to inform listeners that properties of this Node have changed. Also request a canvas update.
property visible#
Whether this node should be drawn or not. Only applicable to nodes that can be drawn.

Architecture Images-Sydney Architects
Barnet, James Johnstone (1827 - 1904)
Born: 1827 Scotland. Died: 1904.
James Johnstone Barnet was clerk of works at the University of Sydney _PHONE_. In 1860 Barnet joined the office of the Colonial Architect, becoming its permanent head in 1865 after acting in the position for two years. As Colonial Architect Barnet was responsible for many of Sydney's significant public buildings until his departure in 1890.
|"The greatest of
all Colonial Architects"
James Barnet was born in Scotland and studied drawing, design and architecture in London before he sailed for Sydney with his wife Amy in 1854. He lived all his Australian years in Glebe (Derwent Street in 1865) and Forest Lodge (Braeside, now demolished).
In 1860, Barnet joined the Colonial Architect's Office. In 1865, he became Colonial Architect and served in this position for 25 years. Barnet's work in Sydney signalled its maturation from a Georgian town to a Victorian city. His work contributed to a sense of stability and civic pride and includes :
The Australian Museum (1864)
The GPO in Martin Place (1866-90)
The Colonial Secretary's building (1878)
The Lands Department building (1876-81, 1888-93)
Further afield, Barnet designed 169 post and telegraph offices, 130 courthouses (including the Glebe Courthouse (1889)) and many other public buildings across the state.
Glebe Courthouse with the police station in the background.
Barnet was 'a promoter of new technologies, used concrete and fire-resistant materials, introduced electricity into his buildings and was first to install a telephone in a government office.' Chris Johnson, the current Government Architect, states that Barnet was the Colonial Architect who most significantly affected the shaping of Sydney.
James Barnet has left Sydney a legacy of iconic and much-loved Victorian buildings. He died at Forest Lodge aged 78 on 16 December 1904 and was buried at Rookwood Cemetery.

The reforestation will consolidate a large forested block along the Embarrass river south of Charleston Illinois at the Warbler Ridge Conservation Area owned by Grand Prairie Friends, a land trust in east central Illinois. Together with the adjacent Fox Ridge State Park, over 3,000 forested acres are preserved, a rarity in this heavily agricultural area. This forested block is regionally important for neotropical migratory songbirds such as cerulean warblers as well as the bat species targeted in the restoration.
Eco Logic developed a planting plan and tree lists based on soil type for the floodplain and upland fields in the project area. Guidelines for sequencing, installation of seed and trees, and maintenance were included in the plan.
In former floodplain agricultural fields along the Embarrass River, Eco Logic started planting the first round of container-grown trees in the fall of 2018. Additional tree plantings occurred in spring of 2019, fall 2019 and spring of 2020. All plantings received a seeding of Virginia wild rye to initiate the establishment of a native herbaceous layer. The fall plantings were relatively small plots of containerized trees installed in flood prone areas, while the spring plantings were bareroot trees that covered the majority of the acreage. The trees suffered significant deer browse in 2019, so Eco Logic worked with Grand Prairie Friends to develop a solar powered electric fencing plan to protect the trees from further deer browse.
Several upland fields totaling approximately 40 acres will be planted with bare-root trees in the spring of 2021. This will conclude the initial reforestation.

The First World Day for Grandparents and the Elderly will be celebrated on Sunday, July 25, announced the Vatican's Dicastery for the Laity, Family and Life.
The theme chosen by Pope Francis for this first commemoration is "I am with you always" (Mt 28:20). This text expresses the closeness of the Lord and the Church to every older person, especially in these challenging times of the Covid-19 pandemic.
After praying the midday Angelus on January 31, 2021, Pope Francis announced that he is establishing a World Day for Grandparents and the Elderly.
The theme, "I am with you always" is also "a promise of closeness and hope that young and old can mutually share," notes the press release.
Not only are grandchildren and youths invited to be present in the lives of older people, but older people and grandparents also have a mission of evangelization, proclamation and prayer, and of encouraging young people in their faith.
To further encourage the celebration of the World Day in local churches and associations, the Dicastery for Laity, Family and Life will offer pastoral tools from mid-June, which will be available on the website _URL_
Pope Francis' concern for the elderly is one of his frequent themes in his speeches and travels. Not only does he advocate for the elderly and their concerns (for example, by decrying the growing push for euthanasia). But he also notes how important the elderly are for society today and the future of the social fabric.


Quick Answer: What Mental Illness Is Winnie The Pooh?
What mental illnesses do Winnie the Pooh characters represent?
Each Character Represents a Different Mental DisorderWinnie the Pooh: Impulsive eating disorder.
Piglet: Generalized anxiety disorder.
Eeyore: Depressive disorder.
Rabbit: Obsessive compulsive disorder (OCD).
Owl: Dyslexia and narcissistic personality disorder.
Tigger: Attention deficit hyperactivity disorder.More items….
What is the real meaning behind Winnie the Pooh?
At the beginning, it explained that Pooh was in fact Christopher Robin's Edward Bear, who had been renamed by the boy. He was renamed after an American black bear at London Zoo called Winnie who got her name from the fact that her owner had come from Winnipeg, Canada.
Was Winnie the Pooh depressed?
Almost 20 years ago, an article appeared in the Canadian Medical Association Journal that argues exactly this. It declared Pooh to be suffering from ADHD, inattentive type, and possibly OCD. Piglet was diagnosed with Generalized Anxiety Disorder, while Eeyore was seen as dysthymic (a type of depressive disorder).
Why is Eeyore depressed?
Who is Mr Sanders Winnie the Pooh?
We don't know who the mysterious Mr. Sanders was; however, there is one unconfirmed explanation: a real-life man by the name of Frank Sanders had a printing press that printed some of Milne's work and was a friend of the man who illustrated the Pooh books.
What mental illness is Tigger?
Meanwhile Tigger suffers from Attention Deficit/Hyperactivity Disorder. This manifests itself in his restlessness and impulsiveness, such as interrupting people and intruding into their privacy, as well as lacking a sense of fear and responsibility.
Does Tigger have ADHD?
Tigger has ADHD, or Attention Deficit Hyperactivity Disorder and Bipolar Disorder because he cannot sit still and rapidly switches moods. Rabbit has OCD or Obsessive Compulsive Disorder because he is extremely orderly.
What mental disorders do Disney characters represent?
What is Winnie the Pooh personality type?
Pooh: Introverted sensing This person sees themselves as happy, calm and if they are honest, a little lazy!
Is piglet a boy or girl?
How did Winnie the Pooh end?
Does Pooh have ADHD?
As per the report, Pooh suffered from more than one disorder–the most prominent one among them being his Attention Deficit Hyperactivity Disorder (ADHD). This psychatric disorder is characterised by a patient's inability to pay attention and an above-normal level of activity in most cases.
When did Winnie the Pooh die?
1934The success of Milne's books made Winnie more famous than ever. When she passed away in 1934 at the age of 20, her death made news around the world. Winnie was so notable that her skull was sent to the Royal College of Surgeons, where it was placed on display last year for the first time.
Is Pooh a girl?
Winnie the Pooh is a boy. He is referred to as "he" in AA Milne's books and in the Disney cartoons his voice has always been provided by a man. But, it turns out that the real-life bear he is named after, was actually a female black bear named Winnie.

A Thousand Ways To Accidentally Cause Someone's Death Without Knowing It
By Your Inaction (Way 999)
Social Media, according to a dictionary, is defined as "websites and applications that enable users to create and share content or to participate in social networking". Billions of people use social media. Studies shows that 49% of the world's total population uses social media. Some use it for fun, some use it to share information, some use it to grow their businesses, some use it to connect and make new friends. Sadly, there are some who uses social media to share others misfortunes. Imagine you were walking by the road side, and you saw a crowd. You walked into the crowd to know what was going on; a young lady has just been hit by a speeding vehicle.
That is an unfortunate moment for the lady, as she lays there, unconscious but still breathing. People walk to the scene, takes picture and walks away. A single dial to 911 or other emergency number could have resulted to an early arrival of an ambulance/medical professionals, which could have helped to save a life. But, just like others, you walked to the scene, (with no intention of making a difference) took some pictures and walked away, leaving the dying lady to her fate. "After all, she's surrounded by people, they will help her".
They will help! The same statement made by 90% of people who had left the scene before you; people who are just like you. You could have stepped up, call others to help you take her to the nearest hospital, or simply dial an emergency number and save a life. But, you choose to take pictures for social media. 10 minutes later, a good samaritan arrived the scene and unlike you, decided to make a different. He took out his phone and dialed the emergency number. An ambulance arrived the scene 10 minutes after they received the call. Unfortunately, the lady had just passed on.
Of cause, you are not responsible for her death. You did not kill her, that's for sure, but she died because you choose not to act. Your inaction is responsible for her death. This is not just a writing for content sake. This has happened and still happening. Like we earlier stated, social media can be used to share and spread information. This includes bad, good and motivational information. Imagine if you took a picture or record a video of yourself trying to save a life. You will probably end up saving a life, share the moments on social media to motivate others to do the same.

The surname labbel was first used as a surname by the people of ancient French region of Gascogne
. It was a name for a person distinguished by great physical beauty. Interestingly, the name labbel was originally derived from the Old French words la belle, which means beautiful.
Early Origins of the labbel family
The surname labbel was first found in Gascony (French: Gascogne), an area of southwest France bordering Spain
, that was part of the "Province of Guyenne and Gascony" prior to the French Revolution, where they held a family seat
in the honor of the seigneurie of De Labels, a village in the Basses-Pyrénées in the arrondisement of de Mauléon.
The Magni Rotuli Scaccarii Normanniae also lists Le Bel in Normandy in 1189. CITATION[CLOSE]
The Norman People and Their Existing Descendants in the British Dominions and the United States Of America. Baltimore: Genealogical Publishing, 1975. Print. (ISBN 0-8063-0636-X) One of the earliest notables of the family was Jean Le Bel (c. _PHONE_), a Flemish chronicle and soldier. He was one of the first chroniclers to write in French instead of Latin. As a soldier, he joined with Jean, Count de Beaumont on his travels to England and Scotland in 1327.
Early History of the labbel family
This web page shows only a small excerpt of our labbel research.Another 125 words (9 lines of text) covering the years 1650, 1573, 1674, 1734, 1703, 1696 and 1768 are included under the topic Early labbel History in all our PDF Extended History products and printed products wherever possible.
labbel Spelling Variations
French surnames were subject to numerous alterations in spelling because of the various cultural groups that inhabited specific regions. Eventually, each region possessed its own local
dialect of the French language. The early development of the French language, however, was also influenced by other languages. For example, Old French was infused with Germanic words and sounds when barbarian tribes invaded and settled in France after the fall of the Roman Empire
. Middle French also borrowed heavily from the Italian language during the Renaissance
. As a result of these linguistic and cultural influences, the name labbel is distinguished by a number of regional variations. The many spelling variations
of the name include Lebel, LeBel, LaBelle, Belle, Bell, Labelle, Label, LaBell, LaBel, LeBelle, LeBaile, LaBaile, Lebaile and many more.
Early Notables of the labbel family (pre 1700)
Notable amongst the family at this time was Firmin Lebel (d. 1573), French composer and choir director; Alexis-Simon Belle (_PHONE_), French painter, member of well known family of painters... Another 29 words (2 lines of text) are included under the topic Early labbel Notables in all our PDF Extended History products and printed products wherever possible.
Migration of the labbel family to the New World and Oceana
In 1643, 109 years after the first landings by Cartier, there were only about 300 people in Quebec. Migration was slow. The fur trade attracted migrants, both noble and commoner. By 1675, there were 7000 French in Quebec. By the same year the French Acadian presence in the Maritimes had reached 500. The French founded Lower Canada, thus becoming one of the two great founding nations of Canada. The family name labbel has made many distinguished contributions in France and New France to the world of science, culture, religion, and education. Amongst the settlers in North America with this distinguished name labbel were Nicolas Lebel who arrived in Quebec from Normandy
in 1657; Pierre Lebel arrived in Quebec from Ile-de-France in 1724; Guillaume LaBelle arrived in Quebec from Normandy

I'm new to VTK and I'm struggling to understand what setOrigin and setPosition mean in vtk3DProp. I'm trying to display multiple cubes ( with specific x, y, z lengths and x, y, z co-ordinates with labels) using vtkAnnotatedCubeActor. Unlike vtkCubeSource, I cannot specify a center or x, y, z lengths for vtkAnnotatedCubeActor. As I understand I can use SetOrigin, SetPosition and SetScale to achieve the result I want but I'm failing to understand how these map to each other. Can anybody explain these to me? Any help is greatly appreciated!
My two cents: setOrigin() sets the object's origin with respect to the world whose origin is 0,0,0. setPosition() sets the postion of the actor with respect to its origin. setOrigin() is very useful if your model has local coordinate systems.
For example, suppose you're modeling the Solar System. You place the Sun actor at origin=0,0,0 and position=0,0,0 so it occupies the center of the Solar System. Then you place the Earth actor 150 million km away from the Sun, but you make Earth's origin at the Sun because the former orbits the latter: origin=0,0,0 and position=150000000,0,0. Then you place the Moon actor with respect to the Earth, not the Sun and 400,000km away from the Earth: origin=150000000,0,0 and position=300000,0,0. This way, you don't need to make complicated computations to make the Moon orbit the Earth while it orbits the Sun with only global heliocentric coordinates.
setScale() will scale the XYZ values of the actor with respect to its origin. In the example above, if you apply a 2x,2x,2x scale to the Moon actor, it will double in size and end up twice further away from the Earth.
I hope this helps casting some light on the subject.


Business Activity Monitoring Design
Version 3
 This document will outline the proposed design for the Business Activity Monitoring (BAM) Design. This work will also encompass the area of Service Activity Monitoring (SAM), which will be treated as a sub-domain, that may have specific views onto the information being collected, to enable service administrators to perform relevant tasks.

 The document is divided into four main sections, each dealing with a separate phase of the BAM architecture.

 Activity Event: Collection, Reporting and Querying

 SAM1-ActivityReporting.jpg

 The first stage of the Business Activity Monitoring design is the "Activity Server". This component has three responsibilities:

 Collection

 Although activity events can be reported directly to the server, it may also be useful to have a capability embedded within a service execution environment, to automate the collection of the information as much as possible.

 The additional benefit of having a "behind the scenes" collection mechanism is that it will be able to infer relationships between various reported activities that are not necessarily visible to the reporting components themselves. A prime example is having an understanding of the XA transaction in which the activities are being reported, as a means to correlate them to the same business transaction.

 The collection mechanism will provide batching capabilities to send the activity event list at configurable intervals or when the list size reaches a threshold.

 Reporting

 An 'ActivityServer' interface will be created to provide the reporting function. This interface can be used directly, if the collection and reporting capabilities are co-located, or via a service API (e.g. REST, JMS, etc.).

 Activity events are reported to the server in a list (i.e. batch) for efficiency. Where reported remotely, they will be serialized to JSON, but represented as a Java object model internally within the server and between its sub-components.

 The Activity Server will have two sub-components:

 ActivityStore

 This component will be responsible for persisting the activity information. The default implementation will be JPA.

 ActivityNotifier

 The Activity Server will be configured with zero or more ActivityNotifier implementations. These will be used to trigger further processing of the activity events and provide the link to the second stage of the Business Activity Monitoring design.

 Querying

 The ActivityServer interface will also support query operations to enable a client to retrieve previously reported activity events. These queries will be passed through to the configured ActivityStore implementation for processing.

 Various query criteria should be supported, including date/time range, event source, etc. However this may be dependent upon the information within the event model.

 Model

 TO BE DEFINED - although an essential part of the Business Activity Monitoring implementation, the actual information within the model does not impact the overall design, so the details of the model can be elaborated throughout the implementation, as well as supporting extensibility to incorporate future requirements.

 Event Processor Network (EPN)

 SAM2-EventProcessorNetwork.jpg

 The second stage of the Business Activity Monitoring design is the Event Processor Network (EPN). The diagram above shows a single 'Event Processor Node' that forms a node within a graph that comprises the 'Event Processor Network'. As the name suggests, this network is responsible for processing a stream of events, with each node (and associated event processor) performing a particular function as part of this processing.

 More than one Event Processor Network could co-exist within a Business Activity Monitoring infrastructure, each with a particular responsibility. For example, phase 1 of the SOA governance work primarily focuses on processing service metric information. This processing could be achieved using an EPN configured with the relevant Service Level Agreements (SLAs) being monitored - with the output from the network being the warnings and alerts to notify appropriate people of pending or actual violations.

 A separate EPN could be configured to accept Activity Events (via a specific Activity Notifier implementation, as discussed previously), as a means of processing business transaction specific activity information, to detemrine other situations of interest. For example, for business transactions associated with a particular customer, an organisation may wish to monitor other metrics that would not otherwise be available with the service wide metrics collected. This mechanism can also be used to ensure that the business transaction is executing according to a valid protocol definition (e.g. derived from a BPMN2 choreography).

 EPN Node

 The Events will initially be introduced into a "well known" named node, which will then process the events and forward them to other nodes in the network if appropriate. As with the Activity Server, the events are passed around as a list (i.e. batch) to enable multiple events to be processed within the same transaction boundary.

 When an event list is received by the EPN Node, it will perform the following tasks:

 - it will iterate over each event in the list, processing them individually
 - if an optional predicate has been configured, then the event must satisfy the predicate for it to be processed further
 - if appropriate, the event will be supplied to the associated Event Processor implementation
 - if the processed event returns a value (possibly transformed), this will be stored ready to be forwarded to other optionally configured nodes in the network
 - if the processed event does not return a value, then no further action is taken - this may occur if the processing is awaiting a number of events before it takes further action (e.g. temporal correlation between events), or it is possible that no further processing is necessary
 - if an exception occurs during the processing, then the original event is added to a retry list
 - when all events have been processed, if any events are in the retry list (and number of retries is less than threshold configured for the node) then the list is resubmitted to the node (possibly after some optional time delay, if supported by the container)
 - transformed events are forwarded to any other nodes that have been configured
 - if notifications have been enabled, then all successfully processed events should be reported to any interested listeners (note, this notification can be used as an input into stage 3 of the Business Activity Monitoring design)

 If an Event Processor implementation maintains state, then it is the implementation's responsibility to handle any persistence and sharing of information with other instances of the EPN in a cluster. (A future enhancement could possibly be to provide container support for this).

 Examples of Event Processor implementations could be CEP rules, BPMN2 based protocol validation, or bespoke implementations.

 EPN Container

 The container is responsible for managing the links between the nodes, handling the notification mechanism, as well as providing some initial entry point for external systems to supply events into the network.

 The initial implementations for the container will be

 (1) in-memory
 (2) JEE (using JMS/MDBs)

 Another possible future supported container could be Storm (_URL_ although the setup of this project's infrastructure appears quite involved, and therefore would be an administrative overhead - however its potential performance advantages may make it worth looking at in the future.

 EPN Configuration and Deployment

 The basic configuration of a network will be generic. The configuration will identify the details associated with each node (e.g. the event processor to use, whether notifications should be emitted, retry threshold, etc) and the connections between them, to form the graph.

 However part of the deployment step may be container specific, and therefore require (a) knowledge of the target container, and (b) the ability to post-process the initial generic configuration with target container implementation details.

 Some tooling will be required to help do this - but also raises the issue of how will updates be handled? If deployed as a single module within AS7 (e.g. using the MDB container approach), then when a new version is available, the EPN will need to be shutdown and then restarted as a whole when deployed. This is probably the safest, as it ensures the network is atomically consistent. If we allow some of the event processor implementation to be changed mid flight, then it may have unknown consequences on the rest of the network, although each EPN node should equally be atomic.

 It will be the containers responsibility to manage stopping and restarting the network. However this still leaves the situation where events queued up for a particular node find that the node no longer exists when the network is restarted. (JEE specific note - queues are independently created/deleted from the mdb deployments, which is good as they are not inadvertantly deleted with remaining messages - but on the other hand it means new nodes need to have their queues created before they can be deployed, and removed nodes may need some tooling to know how to deal with messages left on the queue - e.g. remove or divert are probably the only options).

 Proposal is to include migration details as part of the subsequent configuration. So if a new node will no longer exist in the new graph configuration, then the new configuration will include a temporary node to deal with remaining events - to consume them and either discard or redirect them to other nodes for further processing - so a node cannot simply disappear between versions, it has to enter a deprecated stage where no input source will exist.

 4/4/12 GB: New proposal is to use a versioning technique, similar to that use in BPM engines, where when a new version is available, any existing instances continue to use the old version, while new instances use the new version. In this case, once an initial event list has been triggered against a particular network, it will continue to be processed by that network until completion. However new events will be submitted to the most recent version of a network. Due to the fact that some custom event processor implementations may accompany the network deployment, this means that a network

Bible scholar–translator Bruce Metzger dies: Was general editor for the NRSV
Bruce Metzger, a preeminent New Testament translator and textual critic, died February 13 at his Princeton, New Jersey, home at age 93.
The professor emeritus at Princeton Theological Seminary, where he taught for 46 years, was termed the "greatest American scholar" in his field in the 20th century by Iain Torrance, president of the seminary.
Metzger was a member of the Revised Standard Version translation team that drew heavy criticisms from theological conservatives when the RSV was published in the post–World War II years. In contrast to the King James Version, the RSV drew on an older and wider range of manuscripts and avoided antiquated English.
"I don't think it is an exaggeration to say the RSV would not have happened had it not been for Bruce Metzger," said Bob Edgar, general secretary of the National Council of Churches. The council holds the copyrights for the RSV and the New RSV, published in 1990. Metzger was general editor for the NRSV, which also upset traditionalists for its use of inclusive gender language.
Metzger himself, however, was admired for his careful work, irenic approach and modesty. An ordained Presbyterian minister, he was honored in international circles and helped to improve the biblical Apocrypha translations used by Catholic, Orthodox and Protestant churches.

Reading Sample Data from a URL
You can use a DATA step to read sample data directly from the URL of a SAS/ETS example. Specify the URL in an INFILE statement; the DATA step reads from the HTML source of that URL. To determine the URL of a SAS/ETS example, select the example from the Example Programs (Sample Library). The following DATA steps read from the Seasonal Model for the Airline Series example for PROC ARIMA, whose URL is _URL_
Writing Data to the SAS Log
The following DATA step writes to the SAS log the HTML lines that start with the line following the
 tag and end with the line prior to the
 tag.
data _null_;
infile '_URL_
device=url;
retain pre 0;
input;
if index(_infile_, '
') then pre = 0;
if pre then put _infile_;
if index(_infile_, '
') then pre = 1;
run;
Submitting the Sample to SAS
The following DATA step writes to a file (junk.junk) the HTML lines that start with the line following the
 tag and end with the line prior to the
 tag. The %INC statement submits the file to SAS.
data _null_;
infile '_URL_
device=url;
file 'junk.junk';
retain pre 0;
input;
if index(_infile_, '
') then pre = 0;
if pre then put _infile_;
if index(_infile_, '
') then pre = 1;
run;
%inc 'junk.junk' / nosource;
Submitting the Sample, Title, and Comment Block to SAS
The following DATA step writes to a file (junk.junk) the initial comment block, the title, and the HTML lines that start with the line following the
 tag and end with a line that contains a single semicolon in the first column. The %INC statement submits the file to SAS.
data _null_;
infile '_URL_
device=url;
file 'junk.junk';
retain pre 0;
input;
if pre then put _infile_;
if _infile_ eq ';' then pre = 0;
if index(_infile_, '
') then pre = 1;
run;
%inc 'junk.junk' / nosource;
Not all samples end their DATA steps with a single semicolon in the first column. Depending on the sample you are reading, you might need to change the statement IF _INFILE_ EQ ';' THEN PRE = 0;. For example, if the semicolon that ends the instream data set in the sample is in the fourth column instead of the first column, replace ';' with ' ;'. That is, insert three spaces before the semicolon but inside the single quotation marks.


Hiring in-house counsel? Ask these three questions when assessing candidate fit
May 16, 2018
I am frequently asked to assist our in-house legal department clients in preparing them for interview with their finalist candidate(s). In particular, they often look for key questions to help identify best fit beyond a lawyer's technical or legal skill set for a given role. Here are three questions senior executives frequently explore when conducting interviews with prospective in-house counsel hires:
 1. How would you make a key decision on behalf of the organization in a situation where you were unable to reach the CEO on a time sensitive matter? Perhaps provide a recent example of an issue the leadership team faced along these lines.
This question is designed to assess how a candidate deals with making decisions they aren't normally accustomed to making. The goal is to better understand a candidate's decision process; how they arrive at a decision can be as important as the decision itself. Often, our clients are also interested to see whether a candidate introduces any safeguards to walk back a decision in the event it diverges from company objectives.
 1. How would you deal with a situation where the CEO and the board have divergent views on how to move forward on a company initiative?
This question is designed to assess how a candidate deals with conflicting senior opinions on a matter – you can easily substitute two other senior roles (CEO, CFO, COO etc.) in the question. Clients are often interested to see how a candidate balances competing organizational views against any legal obligations the company may have as it relates to the question.
 1. How do you deal with ambiguity in your decision-making process?
This question is designed to assess how a candidate fills in knowledge and/or procedural gaps as it relates to their duties as counsel. Do they aim to introduce process once a gap is identified? Do they revert to guiding/core principles for the organization? This may also shed some light on a candidate's general risk tolerance as well. We have also seen this question paired with a specific scenario to provide additional insight on how a candidate works through ambiguity in real time.
Whether you are preparing to interview a legal counsel for your company, or are a candidate preparing to be interviewed, turning your mind to these types of questions can help shed light on fit beyond the technical requirements of the role. Of course, if you are looking for further assistance in developing your hiring strategy for your next in-house counsel hire, we would welcome the opportunity to chat with you and your organization on how we might be able to assist.

(Business in Cameroon) - Cameroon's National Meteorological Directorate recently issued its Livestock Weather Assistance Bulletin, forecasting temperatures ranging between 35 and 41 degrees Celsius during the first ten days of April 2024. The institution stressed the negative repercussions on poultry, cattle, and pig production.
To mitigate the adverse effects of these high temperatures on livestock, which could lead to decreased production, the National Weather Authority advised farmers to regularly water their animals, create shade systems, and move animals during the cooler hours of the day. Also, increasing the ventilation rate in buildings used for livestock farming is recommended.
The National Meteorological Directorate states that the Livestock Weather Assistance Bulletin aims to provide rural institutions, pastoral industries, and individuals with weather forecasts and advice concerning livestock conditions, production variations, and disease occurrence throughout different decades and seasons.

One of the inspirations for the painting was this 1897 painting of Laelaps by Charles Knight (_PHONE_). Knight was one of the founding figures of paleoart, working more than a century ago.
He started out by drawing living animals at the zoo, then studied animal anatomy and worked at the American Museum of Natural History. Despite obstacles like vision problems, he went on to paint many murals and illustrations reconstructing extinct life forms. His work has influenced several generations of artists and filmmakers throughout the 20th century.

Is potting soil flammable?
Potting soil is flammable.
Today's potting soil mixes contain organic materials — think peat moss or shredded wood — that easily catch fire.
That's why you should never extinguish a cigarette or other smoking materials in potting soil, the likes of which you see here..
Can you burn soil?
The minerals are predominantly oxides, so do not burn. The interesting part is that organic matter. Lignin and hemicellulose start to break down between 130 and 190 °C, but these reactions do not give out heat so there is no self-sustaining fire. … The minerals are predominantly oxides, so do not burn.
Are plants a fire hazard?
Highly flammable plants can ignite quickly, releasing lots of heat, even if they are healthy and well-watered. In areas experiencing drought, even moderately flammable plants can become more prone to ignite. Characteristics of highly flammable plants include: Dry and dead leaves or twigs.
Why is my plant soil so dry?
A common reason is that the potting mix has dried out and isn't absorbing the water. Most commercial potting mixes contain peat, which holds water well once it has been moistened, but — as everyone who works with sphagnum peat outdoors knows — is difficult to wet the first time.
Can peat moss spontaneously combust?
The one with moistened peat moss was always a couple of degrees cooler than the dry one. A temperature of 39 °C is a long way from the 260 °C needed to spontaneously combust. Peat Moss can not become hot enough on its own to spontaneously ignite.
Does fire destroy soil?
Wildfires have a significant impact on the properties of the soil. The heat of the fire burns away all of the vegetation and organic matter on the surface of the soil, which makes some nutrients more readily available to the soil while turning others into gases that are lost (chiefly nitrogen).
Why does peat burn so well?
Peat fires Peat has a high carbon content and can burn under low moisture conditions. Once ignited by the presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders. … These fires may be responsible for the acceleration in the increase in carbon dioxide levels since 1998.
What happens when soil is too dry?
If the soil is too dry, plants, animals and microorganisms that need more water will not survive in it, and the soil may also become hard and compacted. If soil is too wet, however, it will not contain enough oxygen for some organisms to survive in it either.
Can plants spontaneously combust?
Wills said it's rare, but spontaneous combustion does happen. … "It happens in organic material in the process of decomposition," said Wills. That process lets off heat and with the help of the sun can get hot enough to catch fire.
How does human combustion happen?
The likely explanation for suspected cases of spontaneous human combustion, then, is that there is an external source of ignition—a match, a cigarette, an electrical spark—that sets off the wick effect, but the evidence of it is destroyed by the fire.
How dry should I let my soil get?
For most plants, only water when the soil is dry — not just surface dry, but 2-inches-deep dry. Use your fingers to easily determine soil moisture levels.
Why is my soil not absorbing water?
Hydrophobic Soil & How to Fix It. … Hydrophobic soil occurs when a waxy residue builds up on the soil particles resulting in it repelling water rather than absorbing it. It is most common in sandy soils, dried out potting mix and soils containing unrotted organic matter. You can identify hydrophobic soil by watering it.
Can you revive dry soil?
Rehydrate. Worn out potting soil used over and over again doesn't have many nutrients left for growing plants. Moisten both used and new dried out potting soil by adding water. … If that's the case, put the soil into a watertight container such as bucket or tub.
Can you burn sand?
Sand does not burn. … One has to enrich the sand with highly flammable components to have it burning continuously and hot enough to melt it to glass.
What plants grow after a fire?
Fire-activated Seed Perhaps the most amazing fire adaptation is that some species actually require fire for their seeds to sprout. Some plants, such as the lodgepole pine, Eucalyptus, and Banksia, have serotinous cones or fruits that are completely sealed with resin.
How do you rehydrate dry soil?
Instead of absorbing into the soil, water will run straight through the pot. If your plant is in this situation, use a fork to carefully break up the dry, hardened potting soil, then submerge the entire container in a bucket of lukewarm water. Leave the pot in the water until no air bubbles float to the top.
What is a peat fire?
Peat consists of partially decomposed vegetation and contains varying amounts of carbon, sulphur and nitrogen compounds. When a fire occurs these compounds produce gases that may be very odorous and irritating. Peat smoke also tends to be thicker than the smoke released by other vegetation fires.
How do you revive soil?
To improve sandy soil:Work in 3 to 4 inches of organic matter such as well-rotted manure or finished compost.Mulch around your plants with leaves, wood chips, bark, hay or straw. Mulch retains moisture and cools the soil.Add at least 2 inches of organic matter each year.Grow cover crops or green manures.

But what exactly is 'Flaming'? According to Urban Dictionary, it involves posting emotive, negative messages to provoke an angry or enraged response on social networking sites. Slovenian and British researchers say it will result in your posts receiving a much higher response rate.
The New Scientist reports that the research used "sentiment analysis" to identify emotional content on posts left on the BBC's online forums and with Digg.com. By running algorithms that looked for emoticons, emotional keywords and misspellings, the researchers calculated happiness scores for the posts and found that those with a lower score tended to participate in longer conversations. So if you are the kind of social networker who wants to generate more interest and followers, you're better off writing negative comments than saying 'I love this!'
It is typical of human nature to create social groups out of negative feelings, for example often hash tags like _TAG_ are more successful in trending on Twitter than _TAG_.
At least we're pretty sure that's the reason _TAG_ isn't doing so well.

- Shortened cakes - should remain 10 minutes in their pans, and then unmolded and optionally, turned upright to the wire cake rack.
Cakes baked in rectangular or square pans, jelly roll/sheet and springform pans: many remain in their pans to cool completely. The warm interior of a cake needs a chance to become firm, so any drastic movements jeopardizes its structure. The cake rack allows even air circulation to prevent condensation and sogginess. A spatula or thin knife can be inserted and moved around the edges of the pan to loosen the cake before unmolding it to the cake rack.
- Unshortened or Foam cakes - Sponge cake: unmolded immediately; Angel food and chiffon cake: suspended upside down until cool
This how to baking technique is used with the Frosted Fresh Cherry Cake Recipe Tutorial.
HOW TO TIPS:
1. Take the cake layers immediately from the oven to a wire cake rack and let them sit for 10 minutes. Loosen the sides with a small metal spatula or sharp knife. Invert onto wire cake rack, peel off parchment paper, if using, and place upright with the support of another wire cake rack to cool completely.
SARAH SAYS: A cake layer is fragile when hot when taken right from the oven and will crack easily and fall apart if unmolded too soon from its pan. Letting it sit for 10 minutes in its pan allows it to cool a bit before unmolding, preventing this from happening. If your cooling rack has short legs and sits close to the countertop, condensation easily forms between the two making the underside of the cake wet. So, prop up your cooling rack by placing a same height glass under each corner. Then air can easily circulate around the cake to cool it and no condensation will form.
2. Unmold the second cake layer.

Ounce vs Troy Ounce
Ounce is a unit of measurement of weight and is used in many countries. Roughly equal to 28 grams, ounce is used in many systems but two more popular systems are avoirdupois ounce and troy ounce. Avoirdupois ounce is simply known as ounce and used in all parts of the world but it is troy ounce that holds significance when it comes to measurement of weights of precious metals. Let us see the difference between ounce and troy ounce as any mistake on the part of a buyer can cost him in hundreds of dollars when it comes to gold and silver.
For everyday weighing, it is avoirdupois ounce that is commonly used. If you weigh yourself on a scale, you get your weight in pounds and ounces that are avoirdupois ounces and avoirdupois pounds.
1 avoirdupois ounce =437.5 grains or 28.35 grams
1 avoirdupois pound contains 16 ounces, which makes it 453.6 grams.
Troy ounce is heavier than the ounce used in a grocery store. It is used in precious metals. So when you buy an ounce of gold or silver, you are getting a troy ounce and not ordinary, everyday ounce. It weighs 10% more than common ounce and has 31.1 grams in comparison to ounce that has 28.35 grams.
It is believed that troy ounce is older than an ounce and was used in Troyes France in the Middle Ages. We know that a troy ounce is heavier than an ounce. But since a troy pound contains 12 troy ounces and an avoirdupois pound contains 16 ounces, a troy pound is lighter than an ordinary pound.
So we know now that a troy ounce weighs 31.1 gm whereas an avoirdupois ounce weighs 28.35gm. The formula to convert grocery ounce into toy ounce is as follows.
Regular ounceX0.912 = troy ounces.
- Ounce is a unit of measurement of weights while a troy ounce is especially used for the measurement of precious metals
- Troy ounce is heavier than ordinary ounce
- While ordinary ounce contains 28.35 gm, a troy ounce contains 31.1 gm


FAQ How do I use progress monitors?
From Eclipsepedia
Jump to: navigation, search
A progress monitor is a callback interface that allows a long-running task to report progress and respond to cancellation. Typically, a UI component will create a monitor instance and pass it to a low-level component that does not know or care about the UI. Thus, an IProgressMonitor is an abstraction that allows for decoupling of UI and non-UI components.
Each monitor instance has a strictly defined lifecycle. The first method that must be called is beginTask, which specifies a description of the operation and the number of units of work that it will take. This work value doesn't need to be very precise; your goal here is to give the user a rough estimate of how long it will take. If you have no way of estimating the amount of work, you can pass a work value of IProgressMonitor.UNKNOWN, which will result in a continuously animated progress monitor that does not give any useful information to the user.
After beginTask, you should call subTask and worked periodically as the task progresses. The sum of the values passed to the worked method must equal the total work passed to beginTask. The subTask messages can be sent as often as you like, as they provide more details about what part of the task is currently executing. Again, you don't need to be precise here. Simply give the user a rough idea of what is going on.
Finally, you must call done on the monitor. One consequence of calling done is that any unused portion of the progress bar will be filled up. If your code is part of a larger operation, failing to call done will mean that the portion of the progress bar allotted to your part of the operation will not be filled. To ensure done gets called, you should place it in a finally block at the very end of your operation.
Here is a complete example of a long-running operation reporting progress:
 try {
 monitor.beginTask("Performing decathlon: ", 10);
 monitor.subTask("hammer throw");
 //perform the hammer throw
 //... repeat for remaining nine events
 } finally {
The monitor can also be used to respond to cancellation requests. When the user requests cancellation, the method isCanceled will return true. Your long-running operation should check this value occasionally and abort if a cancellation has occurred. A common method of quickly aborting a long-running operation is to throw OperationCanceledException.

[LeetCode]Design Search Autocomplete System
题目描述：
LeetCode 642. Design Search Autocomplete System
Design a search autocomplete system for a search engine. Users may input a sentence (at least one word and end with a special character '#'). For each character they type except '#', you need to return the top 3 historical hot sentences that have prefix the same as the part of sentence already typed. Here are the specific rules:
 1. The hot degree for a sentence is defined as the number of times a user typed the exactly same sentence before.
 2. The returned top 3 hot sentences should be sorted by hot degree (The first is the hottest one). If several sentences have the same degree of hot, you need to use ASCII-code order (smaller one appears first).
 3. If less than 3 hot sentences exist, then just return as many as you can.
 4. When the input is a special character, it means the sentence ends, and in this case, you need to return an empty list.
Your job is to implement the following functions:
The constructor function:
AutocompleteSystem(String[] sentences, int[] times): This is the constructor. The input is historical data. Sentences is a string array consists of previously typed sentences. Times is the corresponding times a sentence has been typed. Your system should record these historical data.
Now, the user wants to input a new sentence. The following function will provide the next character the user types:
List<String> input(char c): The input c is the next character typed by the user. The character will only be lower-case letters ('a' to 'z'), blank space (' ') or a special character ('#'). Also, the previously typed sentence should be recorded in your system. The output will be the top 3 historical hot sentences that have prefix the same as the part of sentence already typed.
Example:
Operation: AutocompleteSystem(["i love you", "island","ironman", "i love leetcode"], [5,3,2,2])
The system have already tracked down the following sentences and their corresponding times:
"i love you" : 5 times
"island" : 3 times
"ironman" : 2 times
"i love leetcode" : 2 times
Now, the user begins another search:
Operation: input('i')
Output: ["i love you", "island","i love leetcode"]
Explanation:
There are four sentences that have prefix "i". Among them, "ironman" and "i love leetcode" have same hot degree. Since ' ' has ASCII code 32 and 'r' has ASCII code 114, "i love leetcode" should be in front of "ironman". Also we only need to output top 3 hot sentences, so "ironman" will be ignored.
Operation: input(' ')
Output: ["i love you","i love leetcode"]
Explanation:
There are only two sentences that have prefix "i ".
Operation: input('a')
Output: []
Explanation:
There are no sentences that have prefix "i a".
Operation: input('#')
Output: []
Explanation:
The user finished the input, the sentence "i a" should be saved as a historical sentence in system. And the following input will be counted as a new search.
Note:
 1. The input sentence will always start with a letter and end with '#', and only one blank space will exist between two words.
 2. The number of complete sentences that to be searched won't exceed 100. The length of each sentence including those in the historical data won't exceed 100.
 3. Please use double-quote instead of single-quote when you write test cases even for a character input.
 4. Please remember to RESET your class variables declared in class AutocompleteSystem, as static/class variables are persisted across multiple test cases. Please see here for more details.
题目大意：
设计搜索自动完成系统
包含如下两个方法：
构造方法：
AutocompleteSystem(String[] sentences, int[] times): 输入句子sentences，及其出现次数times
输入方法：
List<String> input(char c): 输入字符c可以是26个小写英文字母，也可以是空格，以'#'结尾。返回输入字符前缀对应频率最高的至多3个句子，频率相等时按字典序排列。
解题思路：
Trie（字典树）
利用字典树记录所有出现过的句子集合，利用字典保存每个句子出现的次数。
Python代码：
class TrieNode:
 def __init__(self):
 self.children = dict()
 self.sentences = set()
class AutocompleteSystem(object):
 def __init__(self, sentences, times):

 if self.tnode: self.tnode = self.tnode.children.get(c)
 if self.tnode: ans = sorted(self.tnode.sentences, key=lambda x: (-self.stimes[x], x))[:3]
 else:
 self.stimes[self.buffer] += 1

 for letter in sentence:
 child = node.children.get(letter)
 if child is None:
 child = TrieNode()
 node.children[letter] = child
 node = child
 child.sentences.add(sentence)
# Your AutocompleteSystem object will be instantiated and called as such:
# obj = AutocompleteSystem(sentences, times)
# param_1 = obj.input(c)

Do you know your food habit impacts your luck and prosperity? Sounds wired! But, this is the truth and you can decipher it if you follow Food Astrology. There are very few people who are actually aware that their food habits can strengthen and/or weaken the effects of planets; irrespective of good and bad. Even, due to bad food habits, the most beneficial planet in your birth chart can start giving negative results. And if you visit a truly educated and genuine astrologer in Kolkata, you will be amazed to know how you can reduce or increase the effects of planets just with your food practices.
So, if you want to know how you can increase the beneficial results of planets through your eating habits until you fix an appointment for an astro-consultation, take this blog as your guide.
Improve Results from Planets Through Food Astrology
Yes, you just read it right. Utilizing food astrology, you can magnet positive results from planets. Let us know which food you should list in your diet to improve the planets that are weak in your natal chart, or that you want to strengthen.
- Sun: Sun denotes health, mental health, respect, confidence, success, and father in a birth chart. If it is weak in your natal chart, add wheat, mango, and jaggery to your diet.
- Moon: If the Moon is weak in your birth chart or you are suffering due to your mental health, take sugarcane, sugar, milk, ice cream, white bread, and rice.
- Mercury: Mercury reflects your intelligence quotient. So, if Mercury is inflicted in your birth chart, you can add more and more green vegetables, green daal, and green sweets to your diet.
- Mars: To strengthen Martian energy and bring back confidence and boldness in life start eating jaggery, honey, lentils, pomegranate, and red-colored fruits to your plate.
- Venus: This planet is a karaka of marital bliss and financial improvement as well. If you are suffering with money due to weak Venus, have curd, sugar, candy, sooji white-colored food, and fruits every day. It will also improve your married life.
- Jupiter: Your wisdom and character majorly depend on how Jupiter is posted in your natal chart. To have good results from the planet Jupiter, eat banana, maize, yellow pulse, besan, ghee, gram flour, gram dal, rock salt, yellow fruits, and turmeric with your regular food.
- Saturn: Your karma karaka planet is Saturn. If you want to appease Saturn, you should add food like black pepper, urad dal, sesame seeds, mustard oil, pickle, clove, bay leaves, black salt, black dal, jaggery, and black-colored fruits and sweets to your diet.
- Rahu and Ketu: If you are suffering due to Rahu and Ketu then start including black sesame, chana, mustard oil, black sweets, and black fruits in your diet. It will help to reduce the negative energy of these shadowy planets.
Try these foods based on your zodiac sign as well as planets (weak/strong) in your natal chart. Hope, you will incur results incorporating this food into your diet and get rid of the planetary dilemma. You can consult with Astrologer Shrijit Chatterjee, one of the most genuine astrologer in Kolkata to have personalized food astrology remedies.

Global potato organization says potatoes provided stability during supply chain disruptions, and now the industry deserves to prosper.
PROSPERITY remains a primary focus for the International Potato Center (CIP) which has just launched its annual report.
The significant economic value that root and tuber crops (RTCs) generate for farmers worldwide is highlighted in opening speeches by Director General Simon Heck and the Board of Trustees Chair Helen Hambly Odame.
"The pandemic highlighted the importance of RTCs as they provided stability during global supply chain disruptions. Studies indicate that by 2050, RTCs and fruits and vegetables will account for the largest gains in agricultural economic value in Africa, with similar trends underway in South Asia and Latin America," the report states. "This transformative shift, driven by increased reliance on RTCs under climate change scenarios, allows smallholder farmers in resource-poor communities to benefit from increased market demand. CIP's work empowers them to share in the prosperity built on RTCs."

TAIPEI, TAIWAN -Taiwanese researchers Hui-Mei Chen, Hung-Ming Tu, and Chaang-Iuan Ho published a study in HortScience that explored an array of attitudes toward horticultural activities. The results showed that people engage in gardening and related activities for both psychological and environmental reasons.
The researchers used qualitative and quantitative methods to explore participants' attitudes toward horticultural activities. In the first study, seven themes and several subthemes of attitudes were induced from open-ended interviews with participants. Based on interview results, a questionnaire was designed and a quantitative survey was conducted to identify the dimensions of attitudes toward horticultural activities. The researchers extracted five critical "dimensions of attitudes" toward horticultural activities: increasing positive mood, improving the environment, leisure belief, improving social relationships, and an attitude the researchers label 'escaping'.Respondents rated the dimension of 'increasing positive mood' highest, indicating an emphasis on psychological benefits such as feeling glad, pleased, optimistic, relaxed, tranquil, and comfortable as the essence of their attitudes toward horticultural activities. The researchers also found that that engaging in horticultural activities can provide people opportunities to forget worries, transfer attention, or experience another way of life, or 'escape'. That the respondents rated the dimension of 'escaping' so high emphasizes the importance of the restorative benefits of contact with nature, observed the scientists.
Participants also rated 'improving the environment' as a critical dimension of their attitudes toward horticultural activities. This is a notable change from the well-known Leisure Attitude Scale (LAS), a 1982 model widely used by researchers in the leisure field; the LAS does not include 'improving the environment'.
"To further promote horticultural activity as a form of leisure, it is crucial to first ascertain participants' attitudes about it. Our research shows that horticultural activities are beneficial not only for individuals, but also for the environment", the researchers wrote.
The complete study and abstract are available on the ASHS HortScience electronic journal web site: http://hortsci.
Founded in 1903, the American Society for Horticultural Science (ASHS) is the largest organization dedicated to advancing all facets of horticultural research, education, and application. More information at ashs.org

A method is proposed to control seismic response of a high-rise building considering function maintenance of an elevator. When a cost function for optimal control is formulated to reduce response of rope, response of a building deteriorates especially in high frequency range. In order to overcome this drawback, the proposed method employs frequency shaping linear quadratic Gaussian control and variable gain feedback. Time history analysis is carried out using simulated ground motion and it is verified that the proposedmethod can reduce the response of both a building and rope effectively.

Selective Therapy of High-Risk Calves
As mentioned in the section Selecting the Right Calf, there are several parameters that increase the risk for calves to develop disease. Ideally, we should aim to prevent these high-risk calves from entering the facility through selective purchasing.
Performing a brief exam on each calf entering the facility will help to identify calves that are at high risk of experiencing disease. These high-risk calves could be selectively treated with antimicrobials or supportive therapy (such as oral electrolytes or anti-inflammatory medications) to improve their health and welfare.
What Is a High-Risk Calf?
Calves with the following are at high risk of developing disease:
- Low body weight
- High level of dehydration
- Presence of an enlarged umbilicus with heat, swelling, and pain
- Presence of diarrhea
- Presence of a sunken flank
- Certain source dairy farms
Unfortunately, there is not a large body of evidence on how these calves should be handled at arrival.
It is best to work with your veterinarian to develop a plan on how to manage these high-risk calves in your facilities.

In assessing reduction of concrete strength under irradiated conditions, reference levels are introduced: 1×1020 n/cm2 for fast neutrons and 2×1010 rad (2×105 kGy) for gamma-rays. Concrete structures are regarded as sound as long as irradiance levels accumulated during long-term operation are less than the reference levels.
Most experimental investigations of irradiation effects on concrete were performed in the 1960's and 1970's. However, there is no good explanation of how concrete deteriorates under neutron and gamma-ray irradiation.
Hilsdorf put the primal irradiation test data together to investigate effects of irradiance levels on residual strength ratio of concrete. The reference levels were obtained from his paper. However, the test conditions in which the data quoted by Hilsdorf were obtained are very different from the irradiation and heat conditions usually found in a Light Water Reactor (LWR).
This paper summarizes the interactions between radiation and concrete components and presents the results of gamma-ray irradiation tests on cement paste in order to provide a better understanding of the deterioration mechanisms of concrete under irradiation and heat conditions in LWRs.

Overview
Applies to platforms | Windows | macOS |
Starting from V6.6 of the Windows Collector and V6.16 for the Mac Collector, the installation of the Collector requires two additional parameters from the master Appliance:
 - The Customer Key.
 - The Root Certificate.
These parameters ensure the security of the TCP communications of the Collectors with the Appliances. In the context of a proof of value (PoV) however, it is customary to deploy a few Collectors before having installed the master Appliance. As the master Appliance is needed to generate both the Customer Key and Root Certificate, it is not possible though to install the Collectors before having one master Appliance ready.
To solve this problem, the following method lets you to create a Customer Key and a Root Certificate from an ad hoc master Appliance and later transfer the same Customer Key and Root Certificate to the actual master Appliance that the customer will use in production.
Generating a Customer Key and Root Certificate in the ad hoc Appliance
To generate the Customer Key and Root Certificate:
 1. Set up a Nexthink Appliance including both the Portal and the Engine in an environment that you control. To avoid possible conflicts, preferably install the same version of the Appliance that will later be used in production.
 - You can use, for instance, the Appliance distributed with the official Nexthink Demo kit.
 2. Download the script for generating a new Customer Key and Root Certificate: gen_rck.sh.
 3. Copy the script to your controlled Appliance using any SCP tool.
 4. Log in to the CLI of the Appliance.
 5. Execute the script as root and verify in the output message that a new Root Certificate and Customer Key are generated:
sudo sh gen_rck.sh
 1. Open a web browser and log in to the Web Console of the Appliance as admin.
 2. In the Appliance tab, select the Collector management section on the left-hand side menu.
 3. Under Collector default certificates at the bottom of the page, click the button BACKUP CERTIFICATE AND KEY to get a backup of the generated Root Certificate and Customer Key. The backup file has the name root-ca-backup.tgz. You will later use this file to transfer the Root Certificate and Customer Key to the production Appliance.
Installing the Collectors
After generating the Root Certificate and Customer Key, use them to install the Collectors for your PoV:
 1. Open a web browser and log in to the Web Console of the Appliance as admin.
 2. In the Appliance tab, select the Collector management section on the left-hand side menu.
 3. Look for the section Collector default certificates at the bottom of the page.
 1. Click the button DOWNLOAD CUSTOMER KEY to get the file Nexthink-customer-key.txt.
 2. Click the button DOWNLOAD DEFAULT ROOT CERTIFICATE to get the file Nexthink-root-ca.txt.
 3. Click Yes in the dialog that shows up to confirm the download.
 4. Use the downloaded files for installing the Collectors by means of any of the available methods.
When installing the Collectors, use the appropriate name or IP address to point to your controlled Appliance.
Deploying the Customer Key and Root Certificate in the production Appliance
Once your PoV has been successfully completed and the customer has installed the definitive master Appliance to be used in production, deploy the generated Root Certificate and Customer Key in the production Appliance:
 1. Copy the backup file root-ca-backup.tgz to the master Appliance using any SCP tool.
 2. Download the script for deploying the Customer Key and Root Certificate: deploy_rck.sh.
 3. Copy the script to the master Appliance using any SCP tool.
 4. Execute the script as root, passing the backup file as argument.
 sudo sh deploy_rck.sh root-ca-backup.tgz
 5. Open a web browser and log in to the Web Console of the master Appliance as admin.
 6. In the Appliance tab, select the Network Parameters section on the left-hand side menu.
 7. Type in the External DNS name and the Internal DNS name of the master Appliance.
 8. If the Portal and the Engines are hosted in different Appliances (the master Appliance is not in a master / slave configuration itself):
 1. In the Appliance tab, select the Federated appliances section on the left-hand side menu.
 2. Remove all Engines from the list of federated appliances (if any) by repeatedly clicking the Delete link to the rightmost side of each entry.
 3. Log in to the Web Console of the Appliance hosting one of the Engines that you want to federate as admin.
 4. In the Appliance tab, select the Network Parameters section on the left-hand side menu.
 5. Type in the External DNS name and the Internal DNS name of the slave Appliance (Engine).
 6. Repeat the previous three steps for every Engine that you want to federate.
 9. Back to the Web Console of the master Appliance, select the Collector management section on the left-hand side menu.
 10. Click the button GENERATE CERTIFICATE that is displayed in red.
 11. If your Engines reside in separate slave Appliances, federate them now:
 1. Select the Federated appliances section on the left-hand side menu.
 2. Click ADD APPLIANCE to add a new slave and provide the necessary information.

John Pomeroy, Canada Research Chair in Water Resources and Climate Change at the University of Saskatchewan (USask), has been awarded one of Canada's top honours for outstanding contributions to environmental science.
Pomeroy, who is among the world's most renowned snow hydrologists, will be presented with the Miroslaw Romanowski Medal from the Royal Society of Canada at a ceremony in Ottawa on November 22, 2019. The award recognizes his exceptional contribution to snow research and the cold-season hydrology of mountain regions.
"John's landmark discoveries over his 30-year career have changed the field of hydrology and are critical to cutting-edge understanding of climate warming in cold regions," said Karen Chad, vice president of research at USask. "His stellar accomplishments have helped make USask a national leader in water security research, addressing this global challenge with new science, technology, and policy."
John Pomeroy is director of the USask-led Global Water Futures (GWF) program, the world's largest freshwater research program. An initiative of USask's Global Institute for Water Security, GWF is funded in part with $77.8 million from the Canada First Research Excellence Fund.
He studies on snow distribution, snow cover evolution and energy balance, snow melt, and runoff have defined current understanding of climate warming impacts in cold regions.
Pomeroy uses sophisticated computer simulation models to predict future water supply and quality. The algorithms he has developed have been incorporated into water and climate models around the world. His Cold Regions Hydrological Model is now the standard predictive model in Western Canada.
"He has done more than any hydrologist today in developing what we understand about the science and modelling of cold region processes fundamental to Canada's resources," said Danny Marks, a U.S. Department of Agriculture research hydrologist and former president of the International Commission on Snow and Ice Hydrology.

Why are sulfates in shampoo bad?
Quick Answer
Sulfates in shampoo are bad because they are known to dry out hair when used frequently. Using shampoos that contain sulfates can lead to dryness, irritation and breakage.
Continue Reading
Full Answer
Sulfate shampoos don't need to be completely eliminated from a person's hair care routine if one is currently being used and its performance is satisfactory. Since sulfates are meant to remove buildup, sometimes sulfate shampoos can be useful; however, their usage should be limited to prevent any dryness, irritation or buildup. If the performance of a sulfate shampoo is unsatisfactory, then switch to a sulfate-free shampoo; this will still remove any buildup but will be milder.

Lesbian, Gay, Bisexual and Transgender Youth: An Epidemic of Homelessness
Estimates of homeless youth who identify as GLBTQ range from 20-40%, compared to 3-5% of the total U.S. population. Ray and contributing authors have compiled a comprehensive report on the state of homeless GLBTQ youth for the National Gay and Lesbian Task Force. The report covers the literature on topics including the state of youth homelessness today, federal response to youth homelessness, and the experiences of homeless youth. Several exemplary programs that serve homeless GLBTQ youth are highlighted.
Through a comprehensive review of the available academic research and professional literature, we answer some basic questions, including why so many LGBT youth are becoming and remaining homeless. We report on the harassment and violence that many of these youth experience in the shelter system and we summarize research on critical problems affecting them, including mental health issues, substance abuse and risky sexual behavior. We also analyze the federal government's response to youth homelessness, including the specific impact on LGBT homeless youth of increased federal funding for faith-based service providers.
We also partnered with five social service agencies who have written sections that detail model programs they have developed to improve service delivery to LGBT homeless youth. In order to put a face to all of this research and data, we also include profiles of LGBT homeless youth, many of which were collected through focus groups we conducted at service providers around the country. Finally, in consultation with a number of youth advocacy organizations, we conclude with a series of state-, federaland practitioner-level policy recommendations that can help to curb this epidemic.

What are tracking IDs, and how does the new site help Associates use them?With tracking IDs, Associates can analyze the performance of various Web sites or merchandising strategies while accumulating earnings under a single Associates ID. For example, Associate storeid-20 might use the tracking ID storeid-1-20 to track referrals from one section of his Web site, and storeid-2-20 to track referrals from another section. Each ID would generate earnings for his Associates account storeid-20. He can view earnings for all tracking IDs taken together, or generate reports for each tracking ID individually. If you would like to create tracking IDs for your Associates account, please visit your account and click on "Manage your Tracking ID" link.
We've added several features to the site to help Associates who use tracking IDs analyze their performance and build custom links. You'll:
- Get results faster. The Tracking ID Summary Report now includes data for only those tracking IDs that have activity in the requested time period, making it easier to read and faster to load.
- Analyze performance more easily. Reports data for Associates accounts now include the tracking ID for each transaction. Get all the data you need in a single download instead of generating a report for each tracking ID.
- Save time while building links. You can change the tracking ID to be used in the resulting code at any time while you're building links. This increases your flexibility and eliminates the need for you to repeat steps.

In 2002, teenaged William Kamkwamba had a vision in the very poor African nation of Malawi: A little bicycle generator that powers a light, if connected to a windmill, could allow him to read his schoolbooks at night. As he went further with his plans, he began to see how such a windmill might actually bring the 20th century to his own village. Out this week is "The Boy Who Harnessed the Wind," a book that tells Kamkwamba's story. We talked with William Kamkwamba and Bryan Mealer, the book's co-authors.
"He didn't have washers, so he would go collect bottle caps, beer bottle caps, in front of the bar and flatten them out and put a hole through the middle. He didn't have a drill, so he would use a nail and heat it over his mom's cooking fire, that he would bore holes through this plastic... His cousin found a car battery so he was able to hook the windmill up to a car battery, charge it and then power four more bulbs which he ran through a circuit breaker system that he made out of nails and wire and a magnet that he busted out of a stereo speaker. And it worked."

Schools have been removing bathroom doors, posting bathroom monitors, and even closing bathrooms in their struggles to handle the surging popularity of vaping among middle school and high school students. That has translated into steady business for a U.S. company offering AI-assisted school surveillance capable of alerting teachers and administrators to suspected vaping or bullying in bathrooms.
Soter Technologies originally developed its Fly Sense device with bullying detection in mind. But schools began asking the company about whether it could also help monitor the rise of vaping—also known as Juuling because of the popular Juul vape pens—among students. In response, the company made Fly Sense into a cloud-connected sensor capable of detecting both the telltale signatures of vaping and elevated sound levels that might indicate fighting or bullying.
"Schools typically install the system and see a spike of vaping incidents in the first two weeks," says Derek Peterson, CEO of Soter Technologies. "And then as they continue to go through their school policy plan of reprimanding the students, they start to see vaping incidents in those locations tail off."
More than 200 schools in the United States and Canada have already installed Fly Sense, including schools across at least 23 states. Four school districts in Florida and California have gone all out to become "full-deployment districts" using the Fly Sense system. Other schools are quickly catching on. The company shipped out more than 400 Fly Sense devices in the past month, Peterson says.
The Fly Sense device uses machine-learning AI that has been trained to detect the water vapor signature coming from vaping pens, e-cigarettes, and other vaping paraphernalia. Most vaping devices popular among students consist of a flavored vaping liquid—sometimes called "vape juice"—that includes a hefty dose of addictive nicotine. Once installed, each Fly Sense device can learn the baseline patterns of water vapor in a given bathroom so that the system's thresholds for what counts as an anomaly can be adjusted accordingly.
The constant evolution of vaping has created a technological arms race of sorts, and has prompted Soter Technologies to continuously update its classification library for vaping signatures. For example, the very first version of Fly Sense could not detect the vaping signature from Juul vape pens, which have become especially popular among students.
Much has changed since that time. In August, the company announced version 2.5 of its Fly Sense device and hopes to roll out version 3.0 in spring 2019. Future versions of Fly Sense could potentially even perform more sophisticated chemical analyses that sniff out the difference between a vaping pen signature with nicotine versus tetrahydrocannabinol (THC), the active chemical compound found in cannabis.
Soter Technologies claims that the Fly Sense system generally achieves a vaping detection accuracy of between 70 and 80 percent, and that the system has helped schools achieve a 70 percent decrease, on average, in vaping incidents at locations where the system is installed. Each unit costs US $995, which includes one year of service. Then schools must pay $150 per unit per year to subscribe to the monitoring service.
But AI-boosted bathroom surveillance still needs plenty of human help. Whenever a suspected vaping incident triggers an investigation, schools can confirm whether or not the Fly Sense alert had correctly identified vaping or was a false positive. That feedback helps train the system to become progressively more accurate over time.
Schools that install Fly Sense in their bathrooms get access to Soter Technologies' automated cloud platform that tracks the data being collected by Fly Sense and manages the alert system. School administrators can even manage the system so that only specific teachers will receive alerts on their phones from certain Fly Sense devices.
The dual-purpose mission of Fly Sense means that it also has the capability to keep watch for bullying or fighting by detecting sound levels based on decibels. If the sounds in a bathroom or locker room exceed a certain sound threshold—something that can be adjusted by school administrators—that can trigger a similar mobile alert that could prompt a principal or teacher to go investigate. At the same time, the system's lack of natural-language recognition or identification of voices belonging to particular individuals is meant to avoid student privacy concerns.
"The original intent of the product was to take care of the bullying aspect," Peterson says. "That comes from my own personal history of being five-foot-one in high school and being bullied: I have a personal stake in helping rid the world of bullies."
Whatever the use, Fly Sense seems to appeal to schools seeking to tackle different but similarly troubling national trends. Between one-quarter and one-third of U.S. students report being bullied at school. It's an issue that likely affects millions of students each year. On the vaping side, the 2017 National Youth Tobacco Survey found that approximately 2.1 million students had used e-cigarettes.
The vaping trend in particular has attracted new customers for Fly Sense from the corporate world. Many major corporations prohibit vaping on company grounds and seem as interested as schools in an automated solution such as that being offered by Soter Technologies, Peterson says. But given the meteoric rise of vaping among students in recent years, schools remain a primary market for high-tech solutions as long as they fight to deter vaping behavior on school grounds.
"We probably will have about 20 inquiries a day from schools looking to buy the product," Peterson says.
