In this Voices from the Field post, we archive the presentations from day 1 of the NCII 10-year celebration of the implementation of intensive intervention. On this day, panelists shared stories focused on creating the systems to support implementation of intensive intervention.
These three videos highlight key resources available to support families of students with the most intensive needs at home and as they transition to and from in-school services during the COVID-19 pandemic. The videos speak directly to parents and recommend that parents share the videos (and the mentioned resources) with the team of educators and other professionals working with their child. An easy-to-share handout is included for each of the videos. These handouts identify and link the spotlighted resources that educators and parents can turn to in planning for and supporting children's virtual learning or return to in-school learning.
This three-part Voices from the Field video series profiles how Education Service Center (ESC) 15 in Texas approached implementing the DBI process in San Saba Independent School District (ISD). In these videos, Dedra Carter and Valerie Moos from ESC 15 and Jenna McSherry from San Saba ISD, discuss their experiences and recommendations for other districts implementing DBI.
Staff from the Exceptional Children department in Charlotte-Mecklenburg Schools convened a group of their teachers in Spring 2020 to share their perspectives and ideas. This advisory group includes approximately 20 teachers of exceptional children across Charlotte-Mecklenburg Schools. In this Voices from the Field video, the National Center on Intensive Intervention spoke with four teachers in the advisory group about their work during COVID-19 restrictions.
This series includes video examples and tip sheets to help educators and families in using the NCII reading and mathematics sample lessons to support students with intensive needs. These lessons provide short instructional routines to encourage multiple practice opportunities using explicit instruction principles. The videos and tip sheets describe how educators can use the sample lessons to support instruction in a virtual setting, how educators can share these lessons with parents, and how parents can also implement the lessons to provide additional practice opportunities.

I use the Parallel::ForkManager module for fetching some pages. Below is the relevant code snippet:
use Parallel::ForkManager;
open FILE,">myfile" or die "cann't open file$!";
$pm = new Parallel::ForkManager(5);
foreach $data (@all_data) {
my $pid = $pm->start and next;
#doing the fetching here and get the result on parsed_string
print FILE $parsed_string;
$pm->finish; # Terminates the child process
}
Could someone expain why the results are OK and don't overlap one with the other even there is more than one process writing to the same File ?
网友答案:
Give it something to race. Printing a single line doesn't create a resource contention. Does the output from this program do more of what you expect?
use Parallel::ForkManager;
open FILE, '>', 'myfile' or die "cann't open file$!";
select FILE; $|++;
my $pm = Parallel::ForkManager->new(5);
foreach $data ( 0 .. 100 ) {
 my $pid = $pm->start and next;
 #doing the fetching here and get the result on parsed_string
 print FILE "1. ";

How to Find Underground Water Pipes
Hunker may earn compensation through affiliate links in this story.
If you're planning on digging up your yard for any reason, you're going to want to know where your water pipes are. Performing any kind of construction without this knowledge runs the risk of damaging the pipes, which can flood your yard or your entire home and end up costing a lot of money. You can find underground water pipes in your front or back yard in a very specific way.
Step 1
Purchase a pipe locator device that is capable of finding both metal and plastic pipes. Depending on exactly where you're looking for your underground water pipes, as well as the area in which you live, they could potentially be made of either type of material. For the most accurate reading possible, you need a locator device capable of finding plastic and metal.
Step 2
Set up your pipe locator as directed. How you do this will depend on what type of locator you own. For example, certain pipe locators make a noise (typically with headphones) when a pipe is found. Others display an indication that you're standing above a pipe on a built-in screen.
Step 3
Walk through your yard, aiming the sensor on the pipe locator at the ground as you walk. Your pipe locator will indicate (either visually or audibly) when you're standing above an underground water pipe. You can then mark the position of the pipe according to your own preferences.

Calculate the surface dimensions of Sedimentation Tank
A treatment plant upgrade calls for design of sedimentation basins to handle a flow rate of 8 MGD. The basins are for a Type I suspension with an overflow rate (q0) of 650 gpd/ft2 a length to width ratio of 4:1, a weir overflow rate (qw) of 20,000 gpd/ft, The minimum settling zone depth is 10 ft and 1.5 ft is allowed for freeboard.
(a) If 3 tanks are chosen, what are the surface dimensions of each tank?
(b) What is the required weir length for each tank?
(c) What is the detention time
(a) As = settling zone surface area, ft2 Q = flow rate = 8,000,000 gal/d
q0 = overflow rate =650 gpd/ft2
Surface area of settling tank As = Q/q0 = 8*106 / 650= 12307 ft2
As = L w and Given L = 4 w
Since 3 tanks are used, As per tank = 12307 / 3 = 4102 ft2 = LW= (4W)W = 4W2
W=32f t L = 4W = 128 ft Thus, L = 128 ft and W = 32 ft
(b) Overflow weir length Lw = (Q/tan K)/qw
Lw = overflow weir length (ft)
qw = weir overflow rate (gpd//ft)
Q/tank = flow rate per tank (gpd) = 8MGD/3 = 2.67 MGD
Lw = (Q/tan K)/qw = 2.67 * 106 gpd/ 20000 gpd/ft = 133.4 ft
(c) detention time = V/Q = [128*32*10 ft3] /2.67MGD
= 40960 ft3 / [2.67*106 gal/day* ft3 /7.48gal]
= 0.11475 days = 2.75 hours

The Road to Brass Tactics – Part 3
Over the winter and spring of 2016, we had established two of the core interactions of Brass Tactics: Player Table Movement and Commanding Combat Units. However, while our second-to-second tactical play was pretty well defined, there was the whole aspect of long-term strategy and economic development that needed further definition. As usual we started with a very loose set of objectives and speculated as to how we might fulfill them, and then had some fun as we reached our target experience.
We knew that we wanted more hands-on activities, and pushed for more tactile interactions. However, from early tech demos and our personal experiences with VR we realized that it was important to have physical analogies that made sense. There couldn't be "movement for movement's sake". Pulling a lever to directly manipulate a machine that translated that motion into a result (for example to stamp some metal) is fine. Pulling a lever to accomplish the same thing as pushing a button was not good: it immediately felt fake and tedious.
We cast a pretty wide net during this period, and learned what interactions fit the RTS game model and what did not.
Towers are a core element of the game, the buildings placed on the map to claim territory, as well as being a source for various military units. The player needed easy access to towers during play, and interacting with towers needed to feel natural when built with the Touch controllers.
Resocketable Towers
Our first speculation on tower construction was to have a "toy chest" of towers, a growing group of tactile objects that the player could pick up and place into sockets, and then remove them and socket them elsewhere on the map. "Resocketable" towers in this sense would have had a profound impact on how the game would play as an RTS, but the idea of picking up and placing tactile elements directly on the battlefield fed into our overall fantasy for VR.
There are a number of reasons we didn't keep the feature, but one of the most prominent was how it clashed with movement. The player used the same input buttons to slide the table as they did to pick up a tower, which immediately caused frustration when you grab a tower instead of moving the table. This sort of context-sensitive input works fine when the player has to make a deliberate action or the game's pace is not too high, but table movement is key to success in Brass Tactics… We couldn't sacrifice that.
We could have moved tower pickup to another button (such as the trigger, as we did with upgrades), but then it would have clashed with unit direction instead, simply moving this issue to another button.
Floating Towers
One oddball quirk of moving towers around the map during play is that once you pick one up, you are forced to hold it in one hand while moving with the other. This felt awkward. As an experiment we allowed players to place them in the air in front of them, "floating" as though in zero gravity. The player could just place them out in front of them wherever it was convenient. We even gave them a bit of a visual bob because a rock-solid frozen object in the air feels like a bug and causes players to unintentionally tune them out. The end result worked but was strange, and violated the "physical" world with real gravity that we'd created.
Tower Shelves
We still knew we enjoyed the physical placement of towers, so we still needed a way for players to purchase them. Since we didn't want to rely on menus, a "vending machine" where the player spent some currency to acquire an object required a physical space to live.
The first thing we used for a while were "shelves" that hovered at the player's elbows on the left and right. This gave the player a surface that followed them around the map, where we could put a variety of controls. However, they were well outside the player's normal view, and were problematic if the player walked around the VR space. We considered variants of this such as a "belt" the player could grab from either side and pull into view, but that would result in the player having to look down rather severely. (An apt rule coined by one of our designers was "If the player gets a double chin, you're making them look down too far".)
Regardless of the shape they took, these shelves just felt weak and temporary.
Towers Behind the Castle
We still needed a place to purchase towers, and the castle was a natural option we had to try. The tower "vending machines" were placed back at the player's home base, which we knew would be inconvenient but we wanted to see if it fit with the pacing of a strategy game. In the end this was quite unpleasant, as the player would not only have to move back to their castle to make a purchase, but they had to hold the tower in one hand and move to the build location with the other. It was not comfortable for a majority of players, and required returning to the castle far too often. It amplified player requests for the ability to teleport back to the castle with a button press, which we were trying to avoid for the sake of space and presence.
Finalizing the Palette
We had seen a number of wrist-mounted menus in other games, so we wanted to explore that avenue next. We wanted to make sure that the player interacted with physical objects as always, so it had to unfold somehow, but we wanted to avoid using a button to open it. We opted for rotating the hand palm-up as the signal for the palette to unfold, which was a clear gesture that was different than a typical resting position for the player's hand… When we tried palm-down variants (where the palette would unfold from a wristwatch), there were far too many false positives where the palette opened, due to how the player held their hand naturally.
The palette could have been any shape, so we started with round ones, and experimented with "tiered" versions that helped the player see all the towers mounted… In the end a flat and simple shape worked fine, and we adjusted the palette's angle on the hand for maximum readability. Staggered rows and careful spacing helped the player see each tower label and price. This was definitely the right choice.
Building Upgrades
After tower purchasing, we had to design how our tech tree would manifest… and we knew that the interaction and function would be strongly tied together. In many RTS games, a tech tree is accessed via menus or distributed across the map. Our main goal was to avoid any solution that required parsing a lot of text to use… reading has yet to be a pleasant activity in VR.
Placing upgrade buildings was our primary focus because it was tangible in the way towers were. We quickly decided that these upgrades would be built around the player's castle. This did require returning to the home base (which was inconvenient for tower placement) but since it happened less often, it was less of a hassle. A side effect was that upgrades automatically made your castle seem more elaborate, and when your purchase triggered a castle upgrade, you were generally there to see the (elaborate mechanical) castle upgrade process. Finally, an opposing player could be in awe of your progress by sliding over to your castle and checking it out.
The upgrades were purchased using resources and then socketed into the castle. We had a limited number of sockets, which was further attached to the castle upgrade level. This worked best in VR because the player could clearly see how many sockets they could fill, as well as what happened to the castle when those sockets were filled. By creating a physical analogy we cut down on the menu fiddling and reading in the game significantly.
One side note on the disadvantages managing a lot of information with limited UI is that hardcore players still want to hone their skills with some sort of guide (such as a tree view of the upgrade progressions) and deeper dive that they can refer to during play. Not only did Brass Tactics not provide that extra-deep information in-game (although it was made available on our website), the nature of VR meant referencing outside information during play is nearly impossible… A player cannot (easily) have a web page up on another screen, or glance at a poster-sized printout on their wall… they see the game and only the game.
Our last decision was where the upgrade building "shop" would be positioned… We could have made a second palette to hold them, but we opted to put these buildings behind the castle, outside the normal playspace. We briefly considered a model where the player had to pull a drawer open and pull one of the buildings out, so that the upgrades wouldn't accidentally be picked up… We believed this two-handed operation would not be too tedious for players since it is done eight times a match at the most. However, in the end it was discarded. Two-handed actions felt burdensome unless they created immersion, added control, and reinforced the action. We opted for a "drawer" behind the castle that automatically opened.
Additional Interactions
We had our basic verbs functioning, but we still wanted to explore additional physical interactions, to really explore the "toy box" inspiration of Brass Tactics. Blessedly, Oculus was supportive in giving us time to implement a whole slew of experiments from which we learned a great deal (and hopefully helped future games!).
Table Movement Minigame
When we were fine-tuning the map drag functionality, we created a simple minigame that forced players to move around quickly and precisely. The player simply moved to various random spots around

Home » Do Guinea Fowl Lay Eggs?
Do Guinea Fowl Lay Eggs?
Guinea fowl, also called guineas, are game birds that are becoming popular among backyard poultry owners.
They are indigenous to Africa and one of the oldest gallinaceous birds. Guineas are largely disease-free, hardy, and vigorous birds.
Do guinea fowl lay eggs?
Guinea hens lay eggs but not during the winter months. Laying for the year commences in the spring and continues through the summer and fall. Guinea fowls usually stop laying eggs when the days start getting shorter.
Guinea Fowl on Grass
Except when broody, a guinea hen can lay an egg daily during her laying season. This can yield 6-7 eggs a week per hen.
Do Guinea Hens Lay Eggs?
Guinea hens lay eggs once they mature. The hens lay their first eggs in the first spring of adulthood.
Every day for the first 3 years, a guinea fowl will continue to lay eggs.
Guineas are not particular about where to lay their eggs. Once they find a suitable spot, they make their nests start laying.
Guinea hen nets are usually hard to find. Guineas prefer to nest in long grass, woods, or any place that gives them protection from predators.
When guinea hens are laying their eggs during the day, the male usually acts as a lookout keeping an eye out for predators.
Guineas can sometimes become communal layers. They will lay their eggs in one nest until the number of eggs is sufficient.
Sometimes, this number can be as many as 50. The hens also practice communal brooding, as they take turns sitting on the eggs.
How Many Eggs Do Guinea Hens Lay?
When guinea fowl mate in the wild, they do so in pairs. Domesticated guineas may also adopt this breeding style if there is an equal number of males to females.
These pairs typically wander off as the breeding season arrives to search for good nesting sites.
Guineas are known to be seasonal egg layers. They can lay eggs daily between April and October, with the frequency depending on their location. You can get an egg on most days during their laying season.
Three Guinea Fowl eggs
The number of eggs laid by a guinea hen is usually around 90-130 eggs per season.
On average, one can expect 100 eggs per season. For some prolific layers, like the Black Star and Rhode Island Red, you can expect around 300 eggs a year.
When compared to chickens, guinea hens lay eggs for a shorter period. Also, around 3-5 years of age, their egg production begins to slow down.
How Big Are Guinea Fowl Eggs Compared to Chicken and Duck Eggs?
Guinea fowl eggs are smaller than the eggs of a chicken or a duck.
On average, 2 guinea fowl eggs together add up to the size of a single duck egg or a large chicken egg.
Guinea fowl eggs are usually creamy with light brown spots. The small end of the eggs is more pointed than the egg of a chicken or a duck.
The yolk to white ratio of a guinea fowl egg is higher than that of a chicken egg. The eggshell is harder to crack open than that of a chicken egg.
At What Age Do Guinea Hens Start to Lay Eggs?
Guinea hens start laying eggs around 20-32 weeks of age. They usually lay their first eggs during the spring after they are hatched.
Guinea hens start laying eggs when daylight hours increase and the temperature starts getting warm
They are seasonal layers, and they only lay from spring through fall. In the offseason or the fall of the year they hatched, some young hens may lay a few random eggs.
Guinea Fowl eggs
Do Guinea Hens Make Good Mothers?
Unlike chicken hens, guinea hens do not make good mothers.
While this might sound harsh, here are some reasons why they don't make the best parents to their young.
 - Before all the eggs hatch, some guinea hens tire and are not broody. Some moms move their keets to a new nest without waiting for their remaining eggs to hatch.
 - Some moms stay until the hatch is complete and then get tired of motherhood. They will abandon their keets, who are left alone to die.
 - Some guinea hens end up taking the keets across a damp field where they get wet, freeze, or die.
 - When a guinea hen makes her nest inside a safe henhouse, the eggs will remain unharmed, keeping the keets dry and safe from predators. However, it may allow the rest of the flock to put the keets through a brutal pecking ritual, which they may not survive.
 - When in a coop with other adult birds, keets are exposed to contaminated bedding, worms, and coccidia.
 - In some cases, keets can end up drowning in water without the adults trying to save them.
 - You can discover a guinea hen nest with 50 eggs or more without a broody mom. Predators like snakes, raccoons, or skunks will find the nest and destroy it, eating all its contents and breaking the rest.
 - A mom can accidentally step on her keet, crushing it in the process.
 - Keets often go unwatched or without nurturing, and if they wander from the nest they are left to die.
Some guinea hens still make good moms. They do this by protecting their nest of eggs and keets the best way they can.
Guinea Fowls with Baby
Some guinea hens will try to protect the nest when there is a predator attack. They will hiss and dart at a predator that is bigger and stronger than them.
In some cases, a guinea hen may even die from a predator attack if she is broody outdoors.
How Long Do Guinea Fowl Eggs Need to Incubate?
The guinea fowl egg incubation period usually lasts between 26 to 28 days, which happens to be similar to that of turkeys.
Since guinea hens do not always make good mothers, you can get a chicken to brood around 25 guinea keets in your backyard.
Final Thoughts
Guinea fowl lay eggs, but they are not usually kept for their egg production.
They give around 100 eggs per year, which is significantly below what chickens produce.
If you are rearing guinea fowls for other reasons, having them lay eggs is a plus.
Guinea fowl only lay in warm seasons, so you should only expect eggs from them from spring through summer.

Winter Maintenance Checklist:
– Inspect batteries for signs of damage or leakage
– Ensure proper battery ventilation
– Monitor electrolyte levels (if applicable)
– Address any issues promptly to avoid further damage
Recommended Storage Practices for Golf Cart Batteries During Winter Months
Proper storage practices during the winter months are essential to maintain the longevity and performance of golf cart batteries. Following recommended guidelines can help preserve the batteries' health and ensure they are ready for use when warmer weather returns.
Firstly, it is advisable to fully charge the batteries before storing them. This helps prevent self-discharge and ensures that they retain a higher capacity throughout the storage period. It is important to note that lead-acid batteries self-discharge at a faster rate in colder temperatures.
Next, disconnecting the battery cables or utilizing a battery disconnect switch can help prevent unnecessary drain while in storage. This reduces the risk of self-discharge and extends the overall lifespan of the batteries.
Additionally, storing golf cart batteries in a cool but not freezing environment is crucial. Extreme cold temperatures can harm the batteries, while excessively warm environments can accelerate self-discharge. Ideally, a temperature-controlled area with consistent moderate temperatures is ideal for long-term storage.
Lastly, periodically checking on stored batteries and maintaining their charge level through brief charging sessions can help mitigate potential degradation or sulfation issues that may occur during extended periods of inactivity.
Recommended Storage Practices:
– Fully charge batteries before storage
– Disconnect battery cables or use a disconnect switch
– Store in a cool, temperature-controlled environment
– Periodically check stored batteries
– Maintain charge level through brief charging sessions
In conclusion, cold weather can indeed have an impact on golf cart batteries. The low temperatures can cause the battery's capacity to decrease, leading to a shorter lifespan and reduced performance. Additionally, extreme cold can cause the battery's chemical reactions to slow down, resulting in a slower discharge rate and decreased power output.
To mitigate these effects, it is important to take proper care of your golf cart batteries during colder months. This includes storing them in a climate-controlled environment when not in use and keeping them fully charged. Regular maintenance such as checking the water levels and cleaning the terminals also helps ensure optimal performance. By following these precautions, golf cart owners can minimize the negative impact of cold weather on their batteries and enjoy uninterrupted rounds on the green.
Frequently Asked Questions about Does Cold Weather Affect Golf Cart Batteries?
Do golf cart batteries drain faster in cold weather?
Locate a Indoor Storage Space The ideal location for storing golf cart batteries is in a cool and dry area. It should not be excessively cold or exposed to the elements, but rather cool. Cool temperatures will help reduce the rate at which the battery discharges.
What to do with golf cart batteries in the winter?
To ensure better battery life for your golf cart, it is recommended to keep the batteries on a raised surface like a wood pallet or shelf instead of placing them directly on the ground. Additionally, it is important to store them in a cool and dry area. This will help maintain their charge more effectively.
Can golf cart batteries freeze in the weather?
While it is possible for golf cart batteries to freeze, it is not a common occurrence. When fully charged, the freezing point of a golf cart battery is approximately -80° Fahrenheit (-62°C). As long as you keep your cart connected to the battery charger, there is no need to be concerned about the batteries freezing.
Does cold temperature hurt batteries?
Condensation can occur within batteries in cold temperatures, resulting in corrosion and potentially causing the battery to short circuit. It is important to ensure that your battery is fully charged, as a fully charged battery is less likely to freeze compared to a low-powered one.
Does cold weather affect lithium golf cart batteries?
This also applies to lithium batteries. If the internal temperature of your batteries falls below 32 degrees, the lithium cells cannot take in the same amount of charging current as they could when it was warmer. It is advised not to charge your lithium batteries when the battery temperature is below freezing.
What is the best way to maintain golf cart batteries?
To extend the lifespan of golf cart batteries, it is recommended to avoid fully discharging or exceeding 80% discharge. Regularly testing the batteries using tools like a hydrometer or voltage tester can help monitor their charge level and identify any performance issues. This advice was given on February 8, 2023.

Through a close look at the history of the modernist hooked rug, this book raises important questions about the broader history of American modernism in the first half of the twentieth century. Although hooked rugs are not generally associated with the avant-garde, this study demonstrates that they were a significant part of the artistic production of many artists engaged in modernist experimentation. Cynthia Fowler discusses the efforts of Ralph Pearson and of Zoltan and Rosa Hecht to establish modernist hooked rug industries in the 1920s, uncovering a previously undocumented history. The book includes a consideration of the rural workers used to create the modernist narrative of the hooked rug, as cottage industries were established throughout the rural Northeast and South to serve the ever increasing demand for hooked rugs by urban consumers. Fowler closely examines institutional enterprises that highlighted and engaged the modernist hooked rugs, such as key exhibitions at the Museum of Modern Art and the Metropolitan Museum of Art in the 1930s and '40s. This study reveals the fluidity of boundaries among art, craft and design, and the profound efforts of a devoted group of modernists to introduce the general public to the value of modern art.

Experimental design where materials dominate:
AuchKatzStudio is a French design studio established in 2017 and composed of the visual artist Elsa Belbacha-Lardy and the space and product designer Thomas Thibout.
Based on their individual principles, they aim to combine art and design in a form inspired by minerals. In a world subject to globalization, their empirical work fights against large scale serial design. They work to sublimate the roughness and instability of their materials so as to achieve an experimental design where materials dominate and allude to both solid and fragile matter. Their designer approach is that of a sculptor as they cut their block of polystyrene as one might cut a stone. They let themselves be guided by the spontaneity of their gestures, and the design they have in mind is not the
final product, but rather its starting point. Their work process is based on the colours of material and its capacity to capture the movement of light and the passing of time.
Green Dresser - AuchKatzStudio
Green Dresser is inspired by the mineral and organic world. Its forms and its colors speculate on other worlds where art and design cohabit. Always fascinated by attraction and repulsion and in a sensitive relationship to the mineral and natural world, the Green Dresser mixed sensuality and spontaneity.The aesthetic can be described as an improvisational, process-based approach that runs counter to industrial mass production. This unique piece is made by hand and it aims to strengthen our emotional connection with our domestic environment.

According to an Associated Press story:
The church outside the northern coastal city of Piura was built in 1534 but its mud walls deteriorated over time as Spanish conquistadors abandoned the area, said archaeologist Cesar Astuhuaman of Piura University.
Historical documents discovered in an archive in Sevilla, Spain, helped Peruvian and Spanish academics discover the ruins, whose rectangular stone perimeter remains intact along with an altar, he said in a phone interview Friday.
The church was part of the first settlement established in Peru, which would become the seat of Spanish colonial power, by adventurers led by Francisco Pizarro.

official institutions that govern language change. I'm mainly looking for
information about the French Academy, but if there are other sources, those

Message 2: Alternating Unaccusative Verbs and the Reflexive
Date: 03-Apr-2005
From: Konrad Szczesniak <>
Subject: Alternating Unaccusative Verbs and the Reflexive
Dear Linguists,
I am working on the much-discussed causative analysis of unaccusative verbs
and I'm looking for examples of the following phenomenon in as many
languages as possible:
It is a widely recognized regularity that alternating unaccusative verbs in
some languages (especially Romance and Slavic languages) require a
reflexive clitic in the intransitive/inchoative pattern. For example, in
Polish one says
Dziecko zamroziło mleko (The child froze the milk)
Mleko zamroziło SIE (The milk froze REFLEXIVE-SIE)
This fact is addressed and explained very well by most current approaches
to unaccusativity and the causative alternation. But what these approaches
don't capture very well is that in Polish (and probably in many other
languages), a sizable portion of such unaccusative verbs has non-reflexive
inchoative equivalents:
Mleko zamroziło SIE / Mleko zamarzło
Milk froze REFLEXIVE-SIE / Milk froze (non-reflexive [NR])
Now, the non-reflexive version does not participate in the causative
*Dziecko zamarzło mleko (The child froze[NR] the milk)
Can you send me similar examples of non-reflexive non-alternating
unaccusative verbs in other languages - verbs which are only used in the
inchoative/intransitive structure? I would greatly appreciate examples both
from Slavic and Romance languages as well as ones from non-European
languages, which I will later post as a summary. Thank you.
Best regards,

Aquarium of the Pacific - Online Learning Center - Species Print Sheet
Conservation Status: Safe for Now
There are six sub-species of Pitohuis. The level of toxicity varies by sub-species, geographic location, and diet. Some individuals from some populations do not have toxin. The most colorful, the Hooded Pitohui, P. dichrous, and Variable Pitohui, P. kirhocephalus, are the most toxic.
At the Aquarium
Information about this bird, which is not on exhibit at the Aquarium, is supplied for reference.
Native to New Guinea.
Hooded Pituhois live in the tropical rainforests and jungles of New Guinea from the lower forests to sea level.
Hooded Pitohui, members of the family Corvidae (crows, ravens, jays, etc.), are beautiful passerines, i.e., songbirds. Their wing, head, and tail feathers are black and their back and belly feathers orange. They have black legs ending in sharp claws and a black beak that is strong and sharp. Male and female birds have the same coloration. When threatened, these birds erect their head feathers to form a crest.
Adult birds average 23 cm (9 in) in length and weigh about 65 g (2.3 oz).
These birds are omnivorous, feeding on a variety of berries and insects such as ants. Scientists are currently studying whether the toxin also comes from a small beetle that the birds eat, (Choresine spp,). These New Guinea beetles are distant relatives of a family of beetles 15,289 km (9,500 mi) away in Central and South America, from which poison dart frogs get some of their toxicity.
Since New Guinea does not have marked seasonal changes, nesting time varies according to location and weather patterns. Only one nest of Hooded Pitohuis has been observed. The nest was cup-shaped and composed of tendrils of climbing plants that had been intertwined on a triangular base of branches. At this nest the birds were observed engaging in cooperative breeding in which at least four adults fed the nestlings. Cooperative breeding has been observed in other Corvids.
Nestlings apparently grow their adult plumage quickly. When threatened, they rise up and crest just as adults do. Although the coloration of their feathers mimics that of adults, their plumage contains only a small amount of toxin, far less than that of the toxic adults. Lacking toxin, the young birds may rely on their striking coloration for protection. It is believed that toxin may be transferred to the nestlings and the nest from the belly and back feathers of the adults. Snakes that prey on eggs and nestlings have been observed eating eggs laid by Hooded Pituhois and then rapidly regurgitating them.
Hooded Pitohuis are often found flocking with other birds, including Raggiana Birds of Paradise (Paradissae raggiana spp). This species, like the pitohuis, does not taste very good. Scientists believe that this association is a type of cooperative relationship in which protection is gained by flocking with the highly unpalatable pitohuis.
These birds advertise their bad taste by emitting a strong, unique odor that may be a warning smell, and with bright colors. Striking color patterns and smells meant to warn off predators are called aposematic.
The diet of Pituhois is the source of the toxin, homoBTX, that settles in the dander, skin, and feathers of the birds, concentrating in the breast, belly, and leg feathers. Contact with these birds produces a very unpleasant tingling and long-lasting numbing effect, sneezing, and burning, watering eyes. Research studies have shown that the toxin appears to be a protection against parasites such as lice, and also against predators, including humans. Another New Guinea bird, the Blue-capped Ifrita, (Ifrita kowaldi), also carries the toxin in its skin and feathers. It is found in a mountainous area above 1,500 m (4,930 ft).
Common in New Guinea, Hooded Pitohuis are not listed as a species of concern.
Some New Guinea tribes people believe that a Hooded Pitohui can be eaten if it is held in the hands and mourned as if it were a dead child. However, a 'mourner' must be certain to mourn long enough to make the bird palatable!
Some New Guinea native tribes call the Hooded Pitohui the 'Wobob', which refers to an itchy, uncomfortable skin disease that comes from contact with the bird, and also as "rubbish birds" because of their unique odor and the disagreeable sensations that result from touching them. Pitohui cannot be eaten without a great deal of preparation to rid the skin and flesh of the highly unpalatable and dangerous toxin.
Local traditional New Guineans led scientists to the tiny choresine beetles that Hooded Pituhoi eat. They identified the beetles with the word 'nanisani', the name they use to describe the tingling and numbing sensation of the lips and face that result from contacting both beetles and bird feathers.


real analysis – Does the modulo on a high-dimensional network generally maintain the direction?
We know that for sufficiently large dimensions $ n $ there is a trellis $ L_n $ in $ mathbb {R} ^ n $ whose base region of the Voronoi partition encompasses almost a negligible proportion of a $ (1- varepsilon) $-ball, and is also almost contained in a $ (1+ varepsilon) $-ball, almost a negligible proportion.[1] How does this base region behave like a ball in another way?
We can define "round" and "mod" operations on the space up to a network $ L $ and his score of Voronoi as: $ R_L (v) = arg min _ { ell in L} | v- ell | $ and $ mod_L (v) = v-R_L (v). $
We can also define a "mod ball" as $ mod ^ ast_n (v) = (v / | v |) cdot [|v| – operatorname{round}(|v|/2)]$, which reduces $ v $ in lengths of 2 until it is in the ball.
Fixing radius $ R> $ 0, for a fairly high dimension $ n $, can there be a trellis $ L $ in this dimension with $ | mod_ ast (v) – operatorname {mod} _L (v) | < varepsilon $ for the majority $ v in B (0, R) $ ?
In other words, on a hexagonal grid, compare the modulation reduction of a vector going just above the top of the base hex (for this vector $ mod_L $ is far from $ mod_ ast $) to the one just past the middle of one of the sides of the base hex (for this vector they are close). What behavior dominates in high dimension?
I imagine that no, because I suspect that there are not enough regions of Voronoi adjacent to the base region for a mod reduction on network of a vector just slightly outside of the base region to approximately correspond to the reduction in length 2 of this vector.

Abstract
Fault diagnosis plays a crucial role in ensuring the safe and stable operation of complex industrial systems. Among various existing methods, graph convolutional network (GCN)-based methods can handle graph-structured data commonly found in industrial systems, due to their capability to capture complex relationships within datasets through association graphs. However, conventional GCN models exclusively consider positive association relationship between data, but do not account for the negative one, resulting in embedding vectors that exhibit clustering tendencies and the over-smoothing issue. To address these challenges, a positive–negative GCN-based fault diagnosis method is proposed in this paper. In the method, the conventional association graph is treated as a positive graph, and a corresponding negative one is constructed to capture negative relationships within the dataset. Furthermore, a graph-level data aggregation strategy is introduced to aggregate the information from both association graphs, and incorporate them into the forward propagation process. Fault diagnosis is achieved using a iteratively trained GCN model. Experimental results on two cases demonstrate that the proposed method outperforms existing fault diagnosis methods in terms of diagnostic performance.

The Department of Water and Sanitation has urged all communities along the Vaal Dam and Orange River to consider evacuating and move to high lying areas as water levels rise.
This as 12 flood gates were opened at the Vaal Dam, and outflow at the Bloemhof Dam has been increased to 3000 cubic metres per second.
"All residents of settlements (and in towns) along the banks of the Lower Vaal and Lower Orange Rivers should consider evacuating or moving to higher places that are at least above the 1 in 20- year flood line (a level at which people would likely be safer to be reached by water emanating from the releases).
"These communities should refer to municipal development plans, Local Authorities and Disaster Management Agencies for locations of these flood lines. The water release increases are necessitated by the continuous and intense rainfall that is causing rivers to overflow and dams to spill," said the department in a statement.
The department appealed to all communities along the Vaal and Orange Rivers, especially those along the banks of lower Vaal and Lower Orange Rivers to remain vigilant of possible flooding and to consider evacuating and moving to high lying areas as water levels rise.
The department also urged farmers to remove livestock, movable properties and equipment out and away from the riverbanks. It further urged the general community to avoid any activity that may put their lives in harm.
"The Vaal and Orange River System is experiencing rapid rising water levels due to the heavy rains and the department continues to assess and implement measures to mitigate effects of these floods on its infrastructure and guarantee full capacity on its storage reservoirs after the rainfall season."
To acquire reliable information about prevailing flooding status, the department said it has put in place flood monitoring and forecasting systems that provides real-time data on rainfall, river and dam levels.
"These data are analysed continuously to enable the department to determine the appropriate releases from each dam".
Since rainfall and floods are a natural phenomenon and therefore control of the events may be limited, the department advises against putting essential services and human settlements within parts of the floodplains where there is likelihood of frequent flooding that is within a 1 in 100-year flood line.

Thala Barivat is a historical site located in Thala Barivat district, about 4 kilometers north of Stung Treng provincial town. To reach the site, travelers must cross the Skong and Mekong rivers. There they will find Preah Kor temple, a brick structure constructed in the late 7th and early 8th centuries during the reign of King Jayavarman I. In front of the temple is a large statue of Preah Kor (sacred bull).
Near Preah Kor statue, there is a 10-meter-square yard where every year the Kuoy hill tribe engages in Veay Khel (armor plate traditional fighting). The four-day games, which are part of a Kuoy festival, are held tow or three weeks before Khmer New Year.
There are many small, ancient temples near Thala Barivat, but most of them, such as Prambuon Lveng temple, Srei temple and Angkor Khmao temple have been heavily damaged over time.

During WWI and WWI, war bonds were sold by the U.S. Treasury Department to help fund the war efforts. To promote the bonds and encourage their purchase by citizens, the government produced posters that would promote patriotism and stir pro-American feelings. Below are some of the official posters printed by the U.S. Government Printing Office; notice that each has a strong religious theme. For example, in the WWII posters, the enemy is attacking the Bible — the book that represented the heart and core of America and her beliefs and values. Notice that in the poster with President Franklin D. Roosevelt, a family is gathered around a cross. Others contain Bible themes and even point to the birth of Christ. Among the WWI posters is a mother and child offering a prayer, and an image of religious leader and hero Joan of Arc. Such messages, conveyed by the official mechanisms of the federal government, were never seen to be unconstitutional nor were they even questioned by citizens. To the contrary, Christian and Biblical principles were seen as indivisible from America.

Kids with autism more isolated
Thursday, August 09, 2012
Adolescents with autism are far less likely than their peers with other disabilities to hang out with friends after school or attend group activities.
A Washington University researcher recently found that half of teenage students with autism spectrum disorders were significantly more likely than teens with learning disabilities, mental retardation and speech and language impairments to not be invited out to social activities.
Analyzing data-including surveys of parents and school officials-on 11,000 special education students, Paul Shattuck, an autism expert and assistant professor at Washington University in St. Louis, found that kids with autism are more isolated than their peers and tend to interact in one-on-one situations.
"Not surprisingly, conversational impairment and low social
communication skills were associated with a lower likelihood of
social participation," Shattuck says in the study.
It suggests group activities and programs, such as clubs and sports, as one area of intervention.
But perhaps less obvious is the potential of social networking
in promoting such relationships.
Shattuck recommends that future research study ways to take advantage of electronic media to help those with autism spectrum disorders improve their interactions and connections with others in social situations.

Hydraulic Calculation for Pigging System for Fluid Transfer
FPEC has developed a PC program to calculate the pressure required for pigging system, pipe cleaning by use of a pig, oil transfer, washing with water etc., The fluid transfer pattern as shown in the figure below can deal with. For example, liquid/liquid is corresponding to oil transfer by different kind of oil, gas/liquid to oil drain out by N2 gas, etc.
Furthermore, it can be used when controlling the pressure of receiver. Please contact us if you need to calculate the pressure for pigging system.
Applicable Flow Patterns
Our program can applicable for all of the below flow patterns.
Liquid discharge from pig receiver
When discharge fluid from the pig receiver, it may discharge to the atmosphere or store in a tank. Also, when discharging, two cases may be considered. First one is that pressure of the receiver is adjusted by its outlet valve in order to control the discharge volume, and the second is direct discharge to the atmosphere without controlling the pressure. The pressure required for the pig system differs depending on the discharge method. Our program supports any release method.

Author Judith Barton of Streeter presented an amusing and informative program to members of the Mason Bluebonnet Study Club at the Richard Eckert Center on February 21. A timeline of how her children's book entitled "Too Many Chickens" became a reality was outlined in sometimes fun details, other times serious ones. It all began with her husband's love of raising birds. He ordered 25 chickens and built a house for them. Mrs. Barton said that most of the chickens turned out to be roosters, even the "bonus chicken".
Facinated by this growing story, Mrs. Barton who was a retired art teacher took pictures of the developing saga. The pictures painted a story in her mind.
As the chickens grew, the house became smaller. She said that she could hear them bumping around in there at night....too many chickens.
For a child's birthday present, Barton put together a story using the pictures with appropriate prose to describe each part of the life of the chickens.
Having taken a class on putting together homemade books, she put this first book together and put it in a drawer where it resided until her son took an interest and persuaded her to enhance it and self publish. With added prose and watercolor art depicting her original pictures, the book was published and is available at Benjie's Books and Gifts.
Hints were given on how to put together homemade books and where to find materials needed were given as a part of her program. She showed different types of covers that can be created out of ordinary things one can find around the house. She encouraged members to make their own books as gifts.
Attending Mrs. Barton's presentation were Edna Earle Benton, Maudi Bergmann, Mary Hemphill, Carol Jordan, Tanya Lamoreaux, Sabin Nelson, and hostess Betty Meyer.
The next meeting of the Mason Bluebonnet Study Club will be a study of Texas Heritage in Music. The group will meet in the Methodist Church parking lot on March 21 at 10:45 a.m. and carpool to Brady. Lunch will be at the Patio Cafe, then a guided tour of the Heart of Texas Country Music Museum will follow.

COVID-19 Florida Tracker
The COVID-19 Florida Tracker at Florida Atlantic University is presented to the community as a resource for monitoring key metrics related to the COVID-19 situation in Florida and select South Florida counties. This tracker includes publicly available data provided by the state of Florida. The tracker creators have arranged the figures in a format to give consumers the clearest picture of the coronavirus pandemic in the Sunshine State.
There are three key metrics for monitoring: testing, hospitalizations, and deaths.
Within testing, the key metric is the "positivity percentage," which is the number of positive cases as a percentage of the number of tests. This is a measure of how fast the virus is spreading within the community. It is important to note that the number of cases is largely a function of the number of tests rather than a measure of how fast the virus is spreading.
Within hospitalizations, the key metric is the ratio of occupied beds to total beds, which indicates the percent of occupancy. Also important is the ratio of COVID-19 beds to occupied beds, which measures the mix of COVID and non-COVID patients in hospitals.
With deaths, the key metric is the case fatality rate (CFR), which is calculated as the number of deaths divided by the number of confirmed cases. This is broken down by a number of age groups to highlight the fact that COVID-19 is most dangerous for the elderly.
Because deaths are reported to the state of Florida with a lag of one day to more than one month, it is important to be aware that this number will be updated as deaths are reported for the state. This primarily affects the number of daily deaths for the two most recent weeks.
Below is just one of the many charts produced for this tracking project. Please use the following button to review all of the charts and underlying data.
Disclaimer: The purpose of the FAU COB Tracker is to provide a deeper set of information to facilitate more informed economic policy formation and economic decision making in the presence of COVID-19. The Tracker does not provide healthcare advice or healthcare policy implications. Individuals seeking healthcare advice should consult their physicians.

Hilbert C*-module
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Hilbert C*-modules are mathematical objects which generalise the notion of a Hilbert space (which itself is a generalisation of Euclidean space), in that they endow a linear space with an "inner product" which takes values in a C*-algebra. Hilbert C*-modules were first introduced in the work of Irving Kaplansky in 1953, which developed the theory for commutative, unital algebras (though Kaplansky observed that the assumption of a unit element was not "vital").[1] In the 1970s the theory was extended to non-commutative C*-algebras independently by William Lindall Paschke[2] and Marc Rieffel, the latter in a paper which used Hilbert C*-modules to construct a theory of induced representations of C*-algebras.[3] Hilbert C*-modules are crucial to Kasparov's formulation of KK-theory,[4] and provide the right framework to extend the notion of Morita equivalence to C*-algebras.[5] They can be viewed as the generalization of vector bundles to noncommutative C*-algebras and as such play an important role in noncommutative geometry, notably in C*-algebraic quantum group theory,[6][7] and groupoid C*-algebras.
Inner-product A-modules[edit]
Let A be a C*-algebra (not assumed to be commutative or unital), its involution denoted by *. An inner-product A-module (or pre-Hilbert A-module) is a complex linear space E which is equipped with a compatible right A-module structure, together with a map
 \langle \cdot, \cdot \rangle : E \times E \rightarrow A
which satisfies the following properties:
 - For all x, y, z in E, and α, β in C:
 \langle x, \alpha y + \beta z \rangle = \alpha \langle x, y \rangle + \beta \langle x, z \rangle
(i.e. the inner product is linear in its second argument).
 - For all x, y in E, and a in A:
 \langle x, ya \rangle = \langle x, y \rangle a
 - For all x, y in E:
 \langle x, y \rangle = \langle y, x \rangle^*,
from which it follows that the inner product is conjugate linear in its first argument (i.e. it is a sesquilinear form).
 - For all x in E:
 \langle x, x \rangle \geq 0
 \langle x, x \rangle = 0 \iff x = 0.
(An element of a C*-algebra A is said to be positive if it is self-adjoint with non-negative spectrum.)[8][9]
Hilbert A-modules[edit]
An analogue to the Cauchy-Schwarz inequality holds for an inner-product A-module E:[10]
\langle x, y \rangle \langle y, x \rangle \leq \Vert \langle x, x \rangle \Vert \langle y, y \rangle
for x, y in E.
On the pre-Hilbert module E, define a norm by
\Vert x \Vert = \Vert \langle x, x \rangle \Vert^\frac{1}{2}.
The norm-completion of E, still denoted by E, is said to be a Hilbert A-module or a Hilbert C*-module over the C*-algebra A. The Cauchy-Schwarz inequality implies the inner product is jointly continuous in norm and can therefore be extended to the completion.
The action of A on E is continuous: for all x in E
a_{\lambda} \rightarrow a \Rightarrow xa_{\lambda} \rightarrow xa.
Similarly, if {eλ} is an approximate unit for A (a net of self-adjoint elements of A for which aeλ and eλa tend to a for each a in A), then for x in E
 xe_\lambda \rightarrow x
whence it follows that EA is dense in E, and x1 = x when A is unital.
 \langle E, E \rangle = \operatorname{span} \{ \langle x, y \rangle | x, y \in E \},
then the closure of is a two-sided ideal in A. Two-sided ideals are C*-subalgebras and therefore possess approximate units. One can verify that E is dense in E. In the case when is dense in A, E is said to be full. This does not generally hold.
Hilbert spaces[edit]
A complex Hilbert space H is a Hilbert C-module under its inner product, the complex numbers being a C*-algebra with an involution given by complex conjugation.
Vector bundles[edit]
If X is a locally compact Hausdorff space and E a vector bundle over X with a Riemannian metric g, then the space of continuous sections of E is a Hilbert C(X)-module. The inner product is given by
 \langle f,h\rangle (x):=g(f(x),h(x)).
The converse holds as well: Every countably generated Hilbert C*-module over a commutative C*-algebra A = C(X) is isomorphic to the space of sections vanishing at infinity of a continuous field of Hilbert spaces over X.
Any C*-algebra A is a Hilbert A-module under the inner product = a*b. By the C*-identity, the Hilbert module norm coincides with C*-norm on A.
The (algebraic) direct sum of n copies of A
 A^n = \oplus_1^n A
can be made into a Hilbert A-module by defining
\langle (a_i), (b_i) \rangle = \sum a_i^* b_i.
One may also consider the following elements in the countable direct product of A
\mathcal{H}_A = \{ (a_i) | \sum a_i^{*}a_i\text{ converges in }A \}.
Given an inner product analogous to that on An, the resulting Hilbert A-module is called the standard Hilbert module.

Western Bee Fly
Some pollinators get a better press than others but all are important in the overall puzzle that is Britain's natural world.
Today the Beebomb Bee-log takes a closer look at one of the less heralded pollinators. Where you can see them, how they are coping in our changing world and details on the fascinating, ingenious and unexpected behaviour of the Western Bee Fly.
Common Name: Western Bee Fly or Bomber Fly
Latin Name: Bombyliidae
Information: I know I say this about all the pollinators but this really is a fascinating little beast. Named as a bee fly for it's superficial resemblance to a bumblebee, it is actually a fly with one set of wings. The Western Bee Fly is often commonly called the Bomber fly. A funky nickname given to it for some very interesting behaviour it displays. Look out for the Bee fly in the early part of the summer as it can be seen in flight from March onward. It sets out early as it is looking for solitary bee nests that are being prepared and once it finds one suitable, it hovers over or just inside the entrance (often preferring hillside nests) and 'bombs' it's eggs into the bee nest before it is sealed. The larvae then hatches and becomes carnivorous, feasting on the bee larvae.
They feed on nectar and their furry bodies are efficient at collecting pollen, making them, parasitical behaviour notwithstanding, an important element to a bio-diverse environment.
Description: Making a buzzing noise in flight and with it's often yellowish marking, the Bee Fly can be mistaken at first glance for a Bumblebee. All four sub species found in the UK have a long tongue (proboscis) and most have dark front edge to their wings. See more detail and images of the different UK Bee flies here
Concern Level: Moderate
Distribution: Mainly found in the south and west


Class
UICloudSharingController
A view controller that presents standard screens for adding and removing people from a CloudKit share record.
Declaration
class UICloudSharingController : UIViewController
Overview
CloudKit Sharing provides real-time collaboration between one or more people using your app. A user takes certain steps to make collaboration possible, from inviting people to participate in the collaboration to setting restrictions on what participants can do. To provide these steps to a user, you must make changes to your app. With UICloudSharingController, the changes require minimum effort.
The UICloudSharingController view controller class provides screens, presented within your app, for managing the people, permissions, and access rights associated with a CKShare record. The controller, along with a few lines of your own code, facilitates the setup and management of online sharing between users, making it possible for a user to:
 - Invite people to view or collaborate on a shared record
 - Set the access rights determining who can access the shared record (only people invited or anyone with the share link)
 - Set general or individual permissions (read-only or read/write)
 - Remove access from one or more participants
 - Stop participating (if the user is a participant)
 - Stop sharing with all participants (if the user is the owner of the shared record)
The controller provides these different actions to the user based on the user's role. If the user is the individual sharing the record (where the record is an instance of CKRecord representing the data to share), then the user is called the owner. A user who has access to the shared record and is not the owner is known as a participant. There is no need for you to specify the user's role. The controller determines the role automatically.
Inviting Participants to a New Share
The user who owns the data, represented as a CKRecord, can invite others to view or collaborate on changes to the data. To invite participants, the owner sends the share link to the other people. To provide this capability in your app, create an instance of UICloudSharingController using the init(preparationHandler:) initializer method. You use this initializer method only when the owner is not already sharing the record.
After creating the controller, you present it. The controller displays the Invitation screen. Using this screen, the owner can add participants and set restrictions on the shared record. Once done, the owner sends the share link to the participants.
However, before the owner can send the share link, CloudKit must generate the link. This link generation happens when saving a new CKShare record, but when do you save it? You save the share record in the preparationHandler:.
After the owner's selections are complete, the controller invokes the preparation handler provided in the initializer call. In the handler, you create a new CKShare instance, initializing it with the CKRecord instance that represents the data to share. (This record is called the "root record.") Next, you save the share and root records using CKModifyRecordsOperation. Finally, you return the shared record to the controller or return an error if the save failed. See Listing 1 for an example of this in action.
Listing 1
Presenting the Cloud sharing controller after a bar button tap.
func presentCloudSharingController(_ sender: Any) { guard
 let barButtonItem = sender as? UIBarButtonItem,
 let rootRecord = self.recordToShare else {
 return
 }

 let cloudSharingController = UICloudSharingController { [weak self] (controller, completion: @escaping (CKShare?, CKContainer?, Error?) -> Void) in
 guard let 'self' = self else {
 return
 }
 self.share(rootRecord: rootRecord, completion: completion)
 }

 if let popover = cloudSharingController.popoverPresentationController {
 popover.barButtonItem = barButtonItem
 }
 self.present(cloudSharingController, animated: true) {}
}

func share(rootRecord: CKRecord, completion: @escaping (CKShare?, CKContainer?, Error?) -> Void) {
 let shareRecord = CKShare(rootRecord: rootRecord)
 let recordsToSave = [rootRecord, shareRecord];
 let container = CKContainer.default()
 let privateDatabase = container.privateCloudDatabase
 let operation = CKModifyRecordsOperation(recordsToSave: recordsToSave, recordIDsToDelete: [])
 operation.perRecordCompletionBlock = { (record, error) in
 if let error = error {
 print("CloudKit error: \(error.localizedDescription)")
 }
 }

 operation.modifyRecordsCompletionBlock = { (savedRecords, deletedRecordIDs, error) in
 if let error = error {
 completion(nil, nil, error)
 } else {
 completion(shareRecord, container, nil)
 }
 }

 privateDatabase.add(operation)
}
Adding and Removing Participants from an Existing Share
To allow the owner of an existing share to manage the participants, create the UICloudSharingController instance using the init(share:container:) initializer method.
After you create the controller, present it to show the People screen. From this screen, the owner can:
 - Add and remove participants
 - Change the share's access options from private to public, or public to private
 - Change the share's permissions from read-only to read/write, or vice versa
 - Stop sharing with all participants
Viewing Participants and Leaving a Share
To allow a participant to view the list of participants and remove themselves from a share, create the UICloudSharingController instance using the init(share:container:) initializer method.
After you create the controller, present it to show the People screen. From this screen, the participant can:
 - View the list of participants
 - Copy the share link to send to others (if the owner has made the share publicly available)
 - Leave the share
Presenting the Controller
UICloudSharingController is designed for use in a popover. Therefore, you should always set the popoverPresentationController source information before presenting the Cloud sharing controller. Doing this ensures that the UICloudSharingController instance is displayed properly across all device types.
Listing 2 shows an example of setting the popoverPresentationController before presenting a Cloud sharing controller.
Listing 2
Example of setting the popoverPresentationController before presenting the Cloud sharing controller.
func presentCloudSharingController(_ sender: Any) { guard
 let barButtonItem = sender as? UIBarButtonItem,
 let rootRecord = self.recordToShare else {
 return
 }

 let cloudSharingController = UICloudSharingController { (controller, completion: @escaping (CKShare?, CKContainer?, Error?) -> Void) in
 // Save the share and root records.
 // Call completion(share, container, error) handler.
 }

 if let popover = cloudSharingController.popoverPresentationController {
 popover.barButtonItem = barButtonItem
 }
 self.present(cloudSharingController, animated: true) {}
}
Configuring the Controller
By default, the UICloudSharingController user interface displays a generic thumbnail image and title to the user. You can, however, change these to app-specific representations of the shared record. You accomplish this by setting the controller's delegate property to an object that conforms to the UICloudSharingControllerDelegate protocol, making sure to implement the itemThumbnailData(for:) and itemTitle(for:) delegate methods.
You can also show or hide the permission and access options presented to the user by setting the availablePermissions property on the UICloudSharingController instance.

Cost of Capital : Meaning, Significance, Factors affecting Cost of Capital, Types of Cost of Capital, Measurement of Cost of Capital : FINANCIAL MANAGEMENT
Cost of capital ( k ) is the minimum rate of return that a firm must earn in order to satisfy the expectations of it's investors. In other words, It is the minimum rate of return required on the investment projects to keep the market value per share unchanged.
Significance or Importance of Cost of Capital
This Article Includes
- False Imprisonment : Law Of Tort Notes ( CASES INCLUDED )
- Types of Cost of Capital
- For more Useful notes and important updates, Like our FACEBOOK PAGE and keep yourself updated with UPrepareLaw.
1. If the firms actual rate of return exceeds it's cost of capital and if the return is earned without risk, the objective of shareholder's wealth maximization is achieved. If the actual rate of return is higher, then the excess funds can be used in two ways :
- It can be distributed as dividend to shareholders.
- It can be reinvested for future returns.
2. When Cost of Capital ( k ) is used as the discount rate in capital budgeting decisions, it helps to accept only those proposals where the rate of return is more than the cost of capital.
3. Cost of Capital ( k ) helps to decide the capital structure of the firm. The firm will select only those sources which have the minimum cost. So, the overall ( k ) will be minimum.
Factors Affecting Cost Of Capital
1. Risk free rate of interest ( I ) : It refers to the interest rate which is earned on the risk free or default free security. For Example : Reserve Bank of India.
2. Business Risk ( b ) : It refers to the potential of an organization to earn the returns which will satisfy it's investors.
3. Financial Risk ( f ) : When the debt is present in capital structure, earnings after paying the interests should be enough to satisfy the investors. This risk is known as Financial Risk.
4. Other Considerations / Factors ( o ) : Factors like liquidity, Timing of returns, Shareholder's preference, etc. also affects the cost of capital.
k = I + b + f + o
where, k = Cost of Capital.
I = Risk free rate of return.
b = Business Risks.
f = Financial Risks.
o = Other Factors.
Types of Cost of Capital
1. Specific and Overall Cost of Capital
At a particular point of time, the firm might have raised funds from various sources, i.e., short term as well as long term. But, cost of capital is the combined cost of all the funds used by a firm.
Overall cost of capital is the combined cost of all the funds being used by a firm from any source. It includes the funds following sources :
- Debt : Cost of Debt
- Equity share capital : cost of equity
- Preference share capital : Cost of Preference
- Retained Earnings : Cost of retained earnings
Funds come from a pool of sources. Specific cost of capital is the cost of a particular sources of funds while overall cost of capital is the combined cost ,i.e., cost of all sources of funds.
2. Implicit and Explicit Cost of Capital
Implicit Cost of Capital is the cost of retained earnings expressed in terms of opportunity cost which is associated with returns foregone on retained funds .
In other words, Implicit cost of retained earnings is the return which could have been earned by the investor, had the profit been distributed to them.
Explicit Cost of capital of a particular source may be defined in terms of interest or dividend that the firm have to pay to the supplier of the funds.


Interaction between mantle-derived magma and lower arc crust: quantitative reactive melt flow modelling using STyx
Published on 2018-04-10T15:25:57Z (GMT) by
The magmatic processes occurring in the lowermost arc crust play a major role in the evolution of mantle-wedge-derived melt. Geological evidence indicates that mantle-derived magmas and <i>in-situ</i> products of lower crust partial melting are reacting in a pervasive melt system and are eventually extracted towards higher levels of the crust. Resolving the relative contribution of mantle-derived magma and partial melting products of pre-existing crust is essential to: (1) quantify crustal growth rate; (2) better understand the compositional range of arc magmatic series; and (3) constrain the chemical differentiation of the lower crust. In this study, we present STyx, a new modelling tool, coupling melt and heat flow with petrology to explore the dynamics of storage, transfer and hybridization of melts in complex liquid/rock systems. We perform three models representing a magmatic event affecting an amphibolitic lower arc crust in order to quantify the relative contribution between partial melting of the pre-existing crust and fractional crystallization from mantle-derived hydrous-magma. Our models demonstrate that most of the differentiated arc crust is juvenile, deriving from the differentiation of mantle melts, and that pre-existing crust does not significantly contribute to the total thickness of magmatic products.

Brandon Juhasz: American Bigfoot is Monkey Suit
Ohio photographer, Brandon Juhasz, is a combination of Dr. Frankenstein, Picasso in his cubist period, and photographic outlier. He received his BFA from Bowling Green State University where he was trained in photography and painting and his work seeks to "dissect and understand the entrenched power of images and photography in our culture and the changing nature of the photographic image". I'm showing some selections from his project, American Bigfoot is Monkey Suit.
Brandon's work has been included in many juried and curated exhibitions both locally and nationally including the Hagedorn Gallery in Atlanta for the Atlanta Celebrates Photography festival and MOCA Cleveland.
My work is an exploration of the power and saturation of our image based culture. I explore the concept of photography in contemporary society and its fluid and ubiquitous nature. Photography is now an integral part of living. No longer a curiosity or hobby, photography is as common as driving a car. How does this affect us? How does it affect our ideals and worldview, our self-awareness or our memory? By using images found on the Internet to make new worlds I employ narrative image making to explore failure, desire and life in a post memory, post private hyper documented world.

Backseat Scavenger Hunt
summaryIf you prepare a backseat scavenger hunt for a long car ride, your children may be too busy looking out the window to notice how long you've been on the road.
- The RIF Guide to Encouraging Young Readers
- Alphabet Learning, Games, Vocabulary Building
MATERIALS: Paper and pencil
Before you head out, make up a long list of various things your children are likely to see from the car (or bus or train) window. For example: a license plate beginning with the letter C, an old tire, a tow truck, an overpass, a city that is named after a woman, a McDonalds restaurant, a silo, and so on. Give the children the long list to work on together or divide up the list so that each child is looking for different items. Or let them make up lists for each other. For children who can't yet read, make a picture list by cutting out magazine pictures of signs and other common roadside attractions, like cows and pay telephones. Glue the cutouts on a piece of paper. The children cross items of their lists or circle the pictured objects as they find them. If they wish, they can call out when they see something so the other players can corroborate. Let the winner of the backseat scavenger hunt be the first one out of the car when you stop to stretch your legs, or the one who gets to ride in the front seat for a while.

From its crew members to its crockery, enthusiasts have raked over every aspect of the Titanic's tragic tale. But what about the dogs on board?
There were 12 canines on the doomed ocean liner, three of which survived. Those include a baby Pomeranian, Lady, whose owner, Margaret Hays of New York City, wrapped her in a blanket and carried her into a lifeboat.
The other two dogs to survive were also small, pedigreed pooches who travelled in their owners' cabins. (All the dogs on board belonged to first-class passengers.) Sun Yat-sen, a Pekingese belonging to Henry and Myra Harper (of the Harper & Row publishing dynasty) lived to yip another day, as did a Pomeranian belonging to Elizabeth Rothschild of New York.
The nine dogs confined in the onboard kennel — where they were walked and cared for by crewmembers — all died. Two belonged to American coal magnate William Carter, who reassured his worried children that their pets were safe as they clambered into the lifeboats. His daughter Lucy was later compensated $100 by Lloyds of London for her King Charles spaniel, while his son Billy received $200 for his Airedale.
The other dogs that perished included two Airedales owned by John Jacob Astor IV and his wife, a fox terrier named Dog, and a Great Dane who was the object of a failed rescue attempt by his owner, Ann Elizabeth Isham. She climbed out of a lifeboat after being informed that her dog was too big to join her and returned to the ship's kennel. A few days after the sinking, her body was found by a recovery ship, clutching her beloved canine.
The Titanic's four-footed passengers are included in a new exhibition about Philadelphia families aboard the Titanic at the Widener University Art Gallery in Chester, Pennsylvania.

Lawrence Cemeteries: Haskell Children's Cemetery
Haskell Indian Nations University opened in 1884 as a boarding school for Native Americans. Due to poor conditions, many of those in attendance died and were buried at the southeast end of campus.
There is a marker just outside the cemetery that reads: "The Haskell Cemetery has approximately 100 students buried here. The child's name, tribal affiliation, date of birth and death are engraved on their headstones. Some causes of death were listed as consumption (Tuberculosis), pneumonia, accidental death, typhoid-malaria, heart and kidney problems. The earliest burial was 1885 and the last burial was 1943. Please, be respectful of the offerings left on the headstones."
Legend has it that the cemetery at Haskell is haunted, that you can hear the children buried there cry after dark.
As for me, I went during the day.


text: AbstractDue to the increasing deployment of sensors in water distribution networks (WDNs) for continuous monitoring, hydrodynamic data are readily available for engineers to improve the daily operations of WDNs. In collaboration with Public Utility Board (PUB), Singapore's National Water Agency, an alternative model calibration approach using continuously monitored data is proposed to facilitate PUB's smart water grid (SWG). The generic approach was developed as an integrated solution methodology for practical engineers to conduct a series of systematic analyses daily, namely, (1) estimating the system's daily nonrevenue water (NRW) volume and NRW time series; (2) adjusting the available pumps' operational curves and control statuses, followed by calibrating the system's net demand pattern to fulfill the flow balance accounting for the actual consumption; (3) identifying and rectifying possible offsets in the monitored pressure head values for each sensor station; (4) performing model calibration with anomaly localization analysis when the system's total NRW volume exceeds its assumed background NRW volume; and (5) calibrating other physical properties to fulfill the system's energy balance, especially for the peak demand hours. The effectiveness of our proposed approach was then tested and verified using a real-world WDN having total pipe length of >650 km with available monitoring data. Key findings from the case study analysis include (1) anomaly events localized including, but not limited to, five out of six reported leaks for the selected week to within 400 m with lead time of 1–2 days; (2) the system's initial flow imbalance addressed by estimating the daily NRW volume and localizing the possible anomaly events; and (3) pipe roughness values calibrated to further improve the energy balance in the system, especially during the peak demand hours, by attaining an average mean absolute percentage error (MAPE) score of 2.5%.
