text: This paper assumes that an arrival order lot may contain some defective items, and the number of defective items is a random variable. We derive a modified mixture inventory model with backorders and lost sales, in which the order quantity, the reorder point and the lead time are decision variables. In our studies, we first assume that the lead time demand follows a normal distribution, and then relax the assumption about the form of the distribution function of the lead time demand and apply the minimax distribution-free procedure to solve the problem. We develop an algorithm procedure to obtain the optimal ordering strategy. Furthermore, the effects of parameters are also included.

What are Difference between Covariance and Correlation
Distinguish, differentiate, compare and explain what is the Difference between Covariance and Correlation. Comparison and Differences.
Difference between Covariance and Correlation
Correlation is the standardized form of covariance.
Covariances are difficult to compare. For example: if we calculate the covariances of salary ($) and age (years), we'll get different covariances which can't be compared because of having unequal scales. To combat such situation, we calculate correlation to get a value between -1 and 1, irrespective of their respective scale.

Why Now? - If the Occoquan Dam has been there for 50 years, why are you just now installing a siren system?
Great question! We have installed the sirens for two reasons. First, because of changing regulatory requirements, our regulatory agency - the Federal Energy Regulatory Commission - has suggested that we install a sound-related system to inform people downstream of the dam in the extremely unlikely event of a dam structural failure. The second reason is that when we worked with the communities closest to the dam, namely the Town of Occoquan, it was the Town's feeling that a siren system would be the most effective and desired form of communication to alert people to the extremely unlikely event of a dam failure.
How strong is the dam?
Very strong. The structural integrity of the Occoquan Dam is very sound. In fact, through rigorous maintenance and improvements, it is even stronger today than when it was constructed. The dam is approximately 72 feet tall and 70 feet wide at its widest point. It is anchored to the bedrock below the bottom of the dam and to the sides of the reservoir. It contains more than 100,000 cubic yards of reinforced concrete. That is equivalent to:

Reject Incoming Calls with a Phone Number Block List
The easiest way to reject incoming phone calls from specific phone numbers is to create a "virtual block list". The block list can then be used to filter incoming calls; automatically hanging up on any blocked numbers, and forward other callers as normal. This guide walks you through the process of setting up a virtual block list with sample code for Twilio Functions.
Block list sample code
Here's our phone number block list sample code:
exports.handler = function(context, event, callback) {
 // List all blocked phone numbers in quotes and E.164 formatting, separated by a comma
 let numberBlock = event.block || [ "_PHONE_", "_PHONE_" ];
 let twiml = new Twilio.twiml.VoiceResponse();
 let blocked = true;
 if (numberBlock.length > 0) {
if (numberBlock.indexOf(event.From) === -1) {
blocked = false;
} if (blocked) {
else { // if the caller's number is not blocked, redirect to your existing webhook twiml.redirect(""); }
callback(null, twiml);
When your Twilio phone number responds to incoming calls with this Functions script, the code looks at the phone number detected in our incoming call request, and compares it to the list of blocked numbers in Line 3. If the incoming call is from a blocked phone number, the call is rejected. If the incoming call is not from a blocked phone number, the script redirects to another URL for TwiML.
Here's what you'll need to modify:
Line 3: Update [ "_PHONE_", "_PHONE_" ] with the phone numbers you want to block calls from (in E.164 formatting).
Create a block list Function
 1. Access the Manage Functions page in Console.
 3. Select the Blank template, and then click Create
 4. Edit the Function's Properties fields:
 5. Edit the Function's Configuration fields:
 - CODE: Copy and paste your modified code (see the Block list sample code section above).
 6. Once your Function's fields are correct, click Save
Set your phone number to use your block list function
 1. Access the Active Numbers page in Console.
 2. Click the desired phone number to modify.
 3. Update your phone number's routing:
 - ACCEPT INCOMING: Voice Calls
 - A CALL COMES IN: Function
 - DROP-DOWN MENU: Select your block list function.
 4. Click Save when finished.

Whale watching
The tropical climate of Costa Rica and its warm waters are ideal for these marine mammals that enjoy specific areas along the coast.
The best place to observe whales in Costa Rica is on the Pacific Coast, where humpback whales migrate between July and November and then again between December and March.
The Osa Peninsula is visited by humpback whales that migrate from both the northern and southern hemispheres, meaning that whale populations are concentrated more here than in any other part of the country. Additionally, this large group of whales remains close to the peninsula for a long time, giving Costa Rica one of the longest whale watching seasons in the world.

Fables of the Amazon: Fun Lessons in Ecology
Natural history and ecology are fascinating and complex subjects. Fables of the Amazon make them a whole lot more fun.
Each of these 11 short stories is drawn from actual field observations made by the authors, and as such is scientifically accurate, often presenting little-known insight on the ecology and behaviour of its wildlife characters.
This comic is self-published, and was created in the early 2000s when my friend, mentor and field biologist colleague, Dr. Louise H. Emmons, suggested we collaborate on a completely different venture: a comic book of ecology. Drawing upon decades of field experience and her unique knowledge, Louise wrote most of the stories, and I did the artwork.

From Ohio History Central
Mineral specimens are not so nearly widespread in Ohio as are fossil specimens, but many areas of the state produce interesting minerals. Many of the best specimens of mineral crystals from Ohio have come from limestone and dolomite quarries in northwestern Ohio. Unfortunately for the collector, most of these quarries are now closed to collectors because of safety and legal considerations. Always OBTAIN PERMISSION before collecting on private property. The book, Minerals of Ohio, available from the Division of Geological Survey of the Ohio Department of Natural Resources, is an excellent guide to identification, occurrence, and collecting information on minerals in Ohio.

Charcoal and Pig Iron Production in Brazil: An Example of Our Efforts to Address Human Rights Abuses in Our Supply Chain
Ford's efforts to address human rights abuses in the production of charcoal and pig iron in Brazil illustrate our proactive approach to addressing human rights issues deep in our raw materials supply chain. In 2006, Ford discovered that charcoal produced in Brazil with the use of slave labor had found its way into our supply chain. Pig iron is a key ingredient in steel production, and in Brazil, charcoal is often used as fuel in the production of pig iron (see the Pig Iron Producers graphic below). The charcoal is made from wood harvested in remote areas of Brazil where instances of forced labor have been found to occur. At the time this issue was brought to our attention in 2006, pig iron was purchased directly by Ford and used at our Cleveland Casting Plant.
When we learned of the situation, we immediately stopped sourcing from the site that was identified in the investigation, but we continued dialogue with the supplier and helped them to develop management systems until such time as the supplier could ensure it was not supporting forced labor in the supply chain for pig iron. We then identified all potential points of entry for pig iron in the Ford value chain and engaged with all relevant suppliers, seeking assurances from them that forced labor was not employed anywhere in their value chain. This included an intensive mapping of five to six tiers of suppliers (including importers, exporters and trading companies). We also requested additional detail regarding our Tier 1 suppliers' systems for safeguarding human rights throughout their operations, including procurement.
The Cleveland Casting Plant was closed in 2010, and Ford no longer directly purchases pig iron. Regardless, we have continued, through integrated supplier development programs, to convey our prohibition of forced labor and validate, where possible, supplier compliance. Validation continues to be challenging given the number of supply chain actors between Ford and the charcoal camps in Brazil. For this reason, in 2011 we renewed our inquiry into the potential points of entry for Brazilian pig iron to our supply chain and are evaluating specific supplier progress on management systems to ensure responsible procurement of this material. We also are working with the U.S. State Department, the International Labour Organization and the governing committee of the Brazilian National Pact to Eradicate Forced Labor to seek multilateral solutions that will help to validate information and improve transparency. Ultimately, we hope to enable responsible purchasing decisions throughout the supply chain.

Wisconsin soldiers who served in the Black Hawk War (1832)
Wisconsin Muster Rolls from the Black Hawk War, 1832
During the Black Hawk War against the Sauk and Fox Indians, residents of Wisconsin were assembled into local militia, regular U.S. Army troops were deployed from St. Louis, and fighting units of Menominee and Potawatomi warriors were organized under white leadership. The lists linked below show the names of all soldiers in the 18 companies of "Iowa" militia [i.e., Iowa Co, Michigan Territory; present-day southwestern Wisconsin], plus the Menominee and Potawatomie units and one militia company raised at Green Bay. Not included here are soldiers from the militia of other states or in the regular U.S. Army; the Illinois State Archives lists soldiers from that state.
The rosters of 18 companies of Iowa Co. volunteers are listed first, followed by three Menominee and two Potawatomi companies, and finally by the single company of Green Bay militia. Altogether they total about 600 names on 67 pages.
The original muster rolls from which these typed versions were made are in the records of the General Accounting Office (Record Group 217) at the National Archives in Washington, D.C., misfiled under "Iowa." These lists were created as soldiers mustered out at the end of the conflict; occasional footnotes contain supplemental information from a parallel set of payroll records for each unit. The originals have not been microfilmed, and are published here for the first time. These transcriptions were made by Wisconsin Historical Society genealogical librarian James L. Hansen in 1980. They may be browsed in the left-hand frame of the viewer, and individual names may be searched in the box directly above it.

Join the Christ and creation conversation
The annual Uniting Mission and Education (UME) Faith and Ecology e-seminar hopes again to inspire enriching conversations, as theologians from across Australia come together to address 'Christ and Creation' on November 20. Last year this event attracted more than 100 participants to its inaugural e-seminar.
Uniting Earth is hosting the event, with the main hub in NSW located at Pitt St Uniting Church, 264 Pitt St, Sydney.
Speakers will look to answer the following questions: How can we tell the story of Christ in a way, which is good news for the whole of the Creation that God desires to be reconciled and renewed? What does the reconciliation and renewal of Creation even mean?
In collaboration with Uniting Church colleges, speakers representing each state will be able to engage with participants in person and online.
Uniting Earth's Rev. Dr Jason John is co-coordinating the e-seminar. He says the online aspect means people living in rural areas also can be part of the e-seminar that will include Q&A sessions, as well as workshops.
"Environmental scientists are challenging us to tell the good news in a Creation story," says Rev. Dr John as he explains the purpose of the ecology conversation in November. Key aspects of this conversation will be how human activity is threatening the environment, and how we view God in our world. "The idea that God is in control is even further challenged. We have seized control [of the environment], with far more power than we have wisdom."
The e-seminar will try to answer how the good news fits into this narrative. "[It's about asking] what is the connection between the Christ we follow, and the Creation over which God has, according to our Basis of Union, reasserted claim," says Rev. Dr John.
With in-depth discussions and a diverse range of speakers, participants will come away better prepared, and inspired, to answer questions about Christ and Creation.
The e-seminar runs from 11:30am to 5:30pm (AEST), 20 November. You can be involved in the live conversation at Pitt St Uniting Church (gold coin donation) or online, via another local hub, or from home.

A methodology for topside design and integration in preliminary warship design
This thesis investigates warship topside design and integration and proposes a methodology that provides, during the preliminary design stages, an enhanced topside design capability above that currently available. The feasibility of such a system is demonstrated through a number of individual investigations and ship design studies for both conventional and unconventional naval vessels. A recommended implementation of the methodology, integrating it with the recently produced layout system, is proposed as the way forward. Topside design is a complex task resulting from the requirement to locate all the necessary equipment on the weatherdeck and superstructure of a warship whilst minimising interactions. The current tools and design methodologies fail to cohesively address design issues at the concept stage. This is often due to the specialist nature of the analyses, which require detailed definitions only available later in the design process as well as expert knowledge in the application of the techniques. The proposed methodology provides guidance as different design solutions are developed and evaluated, allowing earlier identification of potential problems. It operates in an 'open' manner providing the naval architect with the flexibility to investigate and analyse the design as it evolves without dictating design decisions or requiring expert application knowledge. The major issues that need to be considered during preliminary warship design are discussed. Current design methods and the shortfalls associated with each of them are considered. A methodology is outlined detailing the principles that are applicable and the important components and characteristics of any solution identified. The major aspects in topside integration are investigated and design tools proposed and evaluated. A framework for the integration of these tools is developed which is suitable for implementation using current computer technology. The suitability of this framework to incorporate other less complex but important topside design issues is evaluated and appropriate techniques identified.

Novel fluorescent diazaoxatriangulenium (DAOTA) pH indicators for lifetime-based self-referenced pH sensing are reported. The DAOTA dyes were decorated with phenolic-receptor groups inducing fluorescence quenching via a photoinduced-electron-transfer mechanism. Electron-withdrawing chlorine substituents ensure response in the most relevant pH range (apparent pKa values of ∼5 and 7.5 for the p,p-dichlorophenol- and p-chlorophenol-substituted dyes, respectively). The dyes feature long fluorescence lifetimes (17-20 ns), high quantum yields (∼60%), and high photostabilities. Planar optodes are prepared upon immobilization of the dyes into polyurethane hydrogel D4. Apart from the response in the fluorescence intensity, the optodes show pH-dependent lifetime behavior, which makes them suitable for studying 2D pH distributions with the help of fluorescence-lifetime-imaging techniques. The lifetime response is particularly pronounced for the sensors with high dye concentrations (0.5-1 wt % with respect to the polymer) and is attributed to the efficient homo-FRET mechanism.

It is no secret that our kids' productivity in school significantly affects their future, which is why we need to provide them with quality school furniture to help them focus and learn. Studies have shown that when kids are furnished with comfortable, functional, and stylish school furniture, they tend to be more productive in the classroom. This blog post will discuss the importance of quality school furniture and how it can help improve your child's productivity! We will also provide tips on selecting quality school furniture for your home or classroom. So, be sure to read on whether you are a parent or a teacher!
How Does Quality School Furniture Affect Learning And Productivity Of Kids?
Quality School Furniture Contributes To the Comfort of Our Kids
One of the main reasons why quality school furniture is essential is because it contributes to the comfort of our kids. When kids are comfortable, they tend to be more focused and attentive in class. This is why selecting school furniture that is ergonomic and comfortable for your child is essential.
Make sure to choose chairs and desks that are the right size for your child and that offer proper support. You may also want to consider investing in adjustable furniture so that it can grow with your child. There are many school furniture suppliers that offer quality and comfortable furniture for kids, so be sure to shop around until you find the perfect pieces for your child's needs!
Also, if you are a teacher, be sure to create a comfortable and inviting learning environment in your classroom by selecting quality furniture that is both functional and stylish.
Quality School Furniture Improves The Quality of Their Work
Another reason why quality school furniture is essential is that it can improve the quality of your child's work. When kids are provided with quality furniture, they have everything they need to complete their work correctly. This indicates that they are less likely to make mistakes, and their work will be of a higher quality overall.
When kids are given the proper tools to complete their work, they tend to take more pride in their work and feel more confident in their abilities. As a result, their schoolwork will improve, and they will be more probably to succeed in the classroom.

Quality School Furniture Helps Them Stay Organized
One of the most crucial things for kids to learn is how to stay organized. This is an essential skill that will benefit them throughout their lives. When kids have quality school furniture, they have a place for everything and can easily keep track of their belongings. This helps to reduce clutter in the classroom and makes it easier for kids to find what they need when they need it.
Additionally, when kids are organized, they tend to be more productive and efficient in the classroom. For instance, if everything has a place, they will know where to find it without wasting time searching for things. As an effect, they will be able to concentrate more on their schoolwork and less on trying to find their supplies. Or, if their desks are cluttered, they may be unable to focus on their work. Thus, it is essential to provide quality school furniture to help kids stay organized and focused in the classroom.
Quality School Furniture Encourages Kids To Be More Active
Another reason why quality school furniture is essential is that it encourages kids to be more active. When kids have furniture designed for movement, they are more likely to get up and move around. This is important because it helps them stay focused and engaged in the lesson. Additionally, being active can help improve a child's overall health and well-being.

Improve Sleep Pattern
Quality school furniture can also help improve sleep patterns in kids. When kids have comfortable furniture, they are more likely to fall asleep quickly and stay asleep throughout the night. This is important because it helps them to get the rest they need to be successful in school.
Additionally, when kids sleep better, they tend to have more energy and focus during the day. As a result, they are more likely to be productive in the classroom.
They Become More Responsible
When kids have quality school furniture, they also tend to become more responsible, and this is because they have a valuable investment in their furniture and want to take care of it.
Additionally, when kids are responsible for taking care of their furniture, they learn how to be more organized and take care of their belongings properly. As a result, they are less likely to lose things or damage their furniture.

They Become More Confident
When children have good classroom furnishings, they grow more confident. This is because sitting on comfy, elegant furniture makes individuals feel good about themselves. Furthermore, giving children the responsibility of caring for their furnishings teaches them to be more autonomous and self-sufficient.
For example, children who are used to having their desks cleaned for them may not know how to care for their furniture on their own properly. However, when children are taught to take care of their furniture, they learn to be more independent and self-reliant. As a result, their self-esteem and confidence grow, which can also benefit them in other areas of their lives.
Quality School Furniture Makes Learning Fun!
Finally, quality school furniture is essential because it can make learning fun! When kids are given stimulating and engaging furniture, they are more likely to enjoy the learning process. Additionally, when furniture is fun, kids are likelier to want to use it and will be less likely to get bored. Thus, providing quality school furniture can help make learning fun and enjoyable for your child!
Quality school furniture is essential for a variety of reasons. It can improve the comfort of our kids and the quality of their work, help them stay organized, encourage them to be more active, and make learning fun! So, consider investing in quality school furniture for your child's classroom, and it will be worth it in the long run!

text: Purpose: Arterial spin labeling (ASL) techniques have been implemented across a diverse range of clinical and experimental applications. This review aims to evaluate the current feasibility of ASL in clinical neuroradiology based on recent improvements to ASL sequences and highlight areas for potential clinical applications. Methods and Materials: In December 2014, a literature search was conducted on PubMed Central, EMBASE, and Scopus using the search terms: ?arterial spin labeling, neuroradiology,? for studies published between 2009 and 2014 (inclusive). Of 483 studies matching the inclusion criteria, the number of studies using continuous, pseudocontinuous, pulsed, and velocity-selective ASL sequences was 42, 209, 226, and 3, respectively. Studies were classified based on several common clinical applications according to the type of ASL sequence used. Studies using pulsed ASL and pseudo-continuous ASL were grouped based on common sequences. Results: The number of clinical studies was 264. Numerous studies applied ASL to stroke management (43 studies), drug testing (21 studies), neurodegenerative diseases (40 studies), and psychiatric disorders (26 studies). Conclusions: This review discusses several factors hindering the implementation of clinical ASL and ASL-related radiofrequency safety issues encountered in clinical practice. However, a limited number of search terms were used. Further development of robust sequences with multislice imaging capabilities and reduced radiofrequency energy deposition will hopefully improve the clinical acceptance of ASL.

31 Appropriate Sympathy Gift Ideas
What is an Appropriate Sympathy Gift?
When a loved one experiences a tragedy or loss, we often wish we could do something to ease their pain. Unfortunately, choosing appropriate sympathy gifts to help them through the grieving process can be challenging, especially because each person deals with grief and sadness in their own way. The most important thing to remember is that anything you do to show love and sympathy will be appreciated.
You're currently reading ➔ [31 Appropriate Sympathy Gift Ideas]
See below for other posts in our sympathy gift guide:
Sympathy Gift Etiquette
Your main goal when choosing appropriate sympathy gifts is to show love and support. However, your message may be better received when you follow the rules of sympathy gift etiquette:
 - Whether or not there is an official service to attend, it is still encouraged to send a gift or card to express your sympathy.
 - The best time to send gifts is during the first two weeks, but if more time has passed, a simple note or card is still acceptable.
 - Charitable donations are often appreciated, particularly if the family has ties or sentimental feelings toward a specific charity. As a general rule, look for the phrase "in lieu of flowers" on any announcements or in the obituaries and follow the instructions given. Sympathy etiquette suggests that you still write a note or card expressing condolences and letting them know you made a donation.

Frequently Asked Sympathy Gift Questions:
How do you sympathize with someone who has lost a loved one?
In addition to cards and gifts, the best way to show your sympathy is by providing service. What can you do to take away some stress during this time? Maybe you can provide a meal, mow the lawn, shovel snow, help with cleaning, or take care of kids.
Is it appropriate to give money in a sympathy card?
Yes, in fact, it is often one of the best ways you can support a loved one. The deceased may have been the one bringing in the majority of the household income, or the survivor may be faced with high funeral costs. Put the money in a card with a kind message and simply mention there is a gift inside so the recipient doesn't wait too long to open it.
Is it appropriate to send flowers to a funeral?
There are circumstances where flowers would not be an appropriate gift. In some cultures and religions, sending flowers to show sympathy during mourning may not be part of their tradition. For example, traditionally Jewish people do not have a culture of sending flowers to the funeral. The same applies to Hindus. If you know the family has no such concerns, then flowers are a great gift for a funeral.
Are group sympathy gifts appropriate?
Sending sympathy gifts as a group works well when the person or family you are supporting is affiliated with your group and is not a particular close friend. For example, multiple coworkers can pitch in for a group gift and each sign the same card.
One of the most helpful ways to provide comfort during difficult times is by making sure your loved ones are well fed. During the grieving process, it is not uncommon for people to let their nutrition slide or to skip meals altogether. Send your loved ones a delicious meal from Spoonful of Comfort, which includes delivery of soup, cookies, and rolls, as well as a personalized note card and a ladle for serving. Check out our Sympathy Soup Gift Baskets today, and get more inspiration for appropriate sympathy gifts on the Spoonful of Comfort blog.

The Dangerous Instagram Trend That's Harming Your Pets
In a worrying trend across social media, pet owners everywhere are dressing up their animals in anti-COVID face masks, a seemingly cute and innocent photo opportunity that could have potentially fatal consequences.
can my dog wear a mask?
Reasons for taking snaps of masked moggies or pooches vary in intention, with some influencers aiming to send out an adorable but persuasive post aimed at anti-maskers, while others are merely on a quest for likes or genuinely fearful their pet might contract the virus.
But whatever people's reasoning, the reaction from veterinarians and animal experts have all been the same and many are now warning pet owners of the severe stress and anxiety face coverings can cause pets.
Why Putting Masks On Pets Is Dangerous
Despite there being rare and isolated cases of dogs and cats contracting coronavirus, there is currently almost no evidence suggesting they can pass the disease on to humans and so masking up a pup is still certainly not a necessary action.
However, in this age of mistrust, many pet owners are ignoring the lack of evidence and still covering up their pets to be on the safe side.
The vast majority though are merely donning their dalmatians in masks for likes and attention on their social media accounts, with many even using it as a photo opportunity to appeal to face covering and COVID sceptics.
poodles in face masks for pandemic
But even if it looks really cute, it certainly isn't clever and according to Melbourne Veterinarian Dr Melissa Meehan, forcing a dog in particular to wear a face mask could kill them in a worst-case scenario.
Speaking to Yahoo News, Dr Meehan said: "As a vet, I am constantly treating dogs and cats that suffer from stress and anxiety, which impacts on their health and mental wellbeing and also causes behavioural issues,
"Putting a mask on a dog or cat can absolutely cause distress."
Forcing an animal to wear such a covering over their face is, therefore, going to be very agitating for them and could cause them health issues if worn for long periods of time.
She also made it clear that masks can impair an animal's breathing, "which can increase their stress levels and could even be fatal."
shihtzu in mask
This is especially true of certain breeds of dogs such as brachycephalic types who already typically suffer from breathing difficulties.
Adding a mask into the equation is only going to make the basic requirement to breathe even more of a struggle, putting their life at risk.
Unfortunately, this is not exactly a new trend either.
In the early days of the COVID-19 outbreak in Wuhan and various areas of China, plenty of people were photographed or filmed placing face masks on their beloved pets.
In their defence, the virus was still a very unknown quantity then and they were probably rightfully worried about the safety of their animals.
do pets need a mask for covid
However, even though there is still much to be discovered, evidence that animals can spread the disease remains non-existent.
This means the current bombarding of mammals in masks on Instagram is cruel and harmful to pets and doesn't actually do them or you any good.
So while we humans definitely should be campaigning to each other to all wear masks, are moggies and pooches shouldn't have any part in the advertising.
We'd much rather see you in a mask than Rover!
Why Pets Don't Need To Wear Face Masks
All over the globe, guidelines from various governments and scientists have promoted the wearing of masks to help prevent the spread of coronavirus, with some declaring it mandatory in closed public spaces.
For example, in the UK this week, face coverings were made compulsory in shops, supermarkets and on public transport, a rule many people have instantly adhered to.
why pets dont need masks for coronavirus
In a woeful case of timing though, a pet cat also became the first case of its kind to test positive for coronavirus in the UK, sending many people into panic mode.
So even if people are merely uploading masked photos of pets for fun or because it's 'cute', you may well be convincing other nervous and worried pet owners that popping a face covering on your pet is the done thing!
why cats shouldnt wear masks covid
But although several cats and dogs have now tested positive for coronavirus around the world, it remains a rare occurrence.
It's also important to note that each animal to contract the virus so far has displayed very low traces of it in their system and have also been unable to spread it to another human.
The World Organisation for Animal Health has stated that currently, there is no evidence to suggest that animals infected by humans are playing a role in the spread of COVID-19,
Human outbreaks are driven by person-to-person contact and to date, there is no evidence that companion animals have spread the disease.
This means that the handful of pets who have been unlucky enough to catch the disease have done so from their owners, and not the other way round!
So if you're truly worried about your pet catching coronavirus, it's YOU who needs to wear a mask rather than them, as well as limit contact with them if you suspect you have symptoms.
Why would you ever want to hide away that adorable face anyway!?

A compass needle undergoes forced oscillations under the influence of a uniform magnetic field and a rotating magnetic field with angular velocity (black arrow). The compass needle has a moment of inertia, a friction constant, and a magnetic moment ℳ. This is a simple example of a system that shows chaotic motion. In a real experiment it is impossible to repeat a particular motion from initial conditions and because the system is chaotic.

How to determine if two cones with vertices at origin, intersect?
Asked by Doctor61
on 6 Feb 2013
Accepted Answer by Sven
Suppose I have two different sets of data points in 3d, that each are in a different tilted plane (different theta,phi,r of normal). I manage to find the enclosing circle for each of these sets of points (center and radius). Now imagine a solid angle (cone) with the vertex at origin and base at the enclosing circle. So I have two cones that have different heights, and their middle axis is at a different theta and phi. Now how can I figure out if these cones have any overlap (intersection) or not? And also if they are not overlapping how close are they, this is rather complicated to define and I still haven't figured out a suitable proximity measure. But maybe you guys out there have some ideas?

EDIT: discard this comment; I wrote it before realizing that your cones have both their tip at the origin.
You will probably find a lib. that does it, but if you had to do it "by hand".. you could start by computing the distance between the axes of both cones. This is done by computing the scalar product between a vector made of two arbitrary points from the two axes respectively and a unit vector orthogonal to the two axes. You get the latter by normalizing the cross product between two arbitrary directional vectors defining the two axes.
It would not be too complicated then to find radii of both solid angles at closest locations between the two axes. However, what you call "overlapping" is vague. If the two cones have an intersect, its geometry will be quite complicated.
No products are associated with this question.

Hi again Doc,
First thing you can do is check the dot product between the normal vectors of both cones' planes. If the dot product is less than zero, the cones cannot intersect. If the dot product is one, then the cones must intersect.
An easier way to think about "nice" 3D shapes (like cones) is to ask if it can project to 2D. In this case, happily the problem can be reduced to 2D.
You've got two "plane normal vectors" that intersect at the origin. This means they are co-planar. If you find this plane (which is straight forward with a couple of cross products), then project the outline of the cones onto this plane, you've reduced the problem down to a question of "does triangle A intersect triangle B".
Or, more simply:
 - Get the "apex angle" of each cone/triangle from its normal vector
 - Get the angle subtended between the normals of each plane
 - If the sum of the apex angles is greater than this subtended angle, your cones/triangles intersect.
So, let's say you know a few things:
1. The unit vectors of each plane's normal vector:
zVec1 = rand(1,3); zVec1 = zVec1/norm(zVec1)
zVec2 = rand(1,3); zVec2 = zVec2/norm(zVec2)
2. The "height" of each triangle (ie, the distance from your cone plane to the global origin:
ht1 = 10
ht2 = 7
3. The "width" of each triangle (ie, the radius of each cone):
wdth1 = 2
wdth2 = 3
Now you've got all you need to calculate the apex angle of each cone (ie, between the cone wall and the normal vector):
ang1 = atand(wdth1/ht1)
ang2 = atand(wdth2/ht2)
And the angle between the two plane normal vectors:
twoVecDotProd = dot(zVec1,zVec2)
angBetweenNormVecs = acosd(twoVecDotProd)
Now you've got your result:
conesIntersect = twoVecDotProd>0 && ang1+ang2 >= angBetweenNormVecs
Does that work for you?
on 7 Feb 2013
Hi Sven, thanks again for your valuable help.
This method is a very smart solution to my problem. But I have tried it on some random samples and it seems it does not perform correctly. BTW I have two questions about it: first, when you say "width of each triangle (ie, the radius of each cone)", do you basically mean the diameter of the circles I have as the base of the cones? Cause later you divide it by 2, in order to find the apex angle.
Also, I am a bit confused why you chose the inequality so that there is an intersection when ang1+ang2 is larger than angBetweenNormVecs, I would have assumed the opposite. Needless to say, I tried the opposite too and in some random runs it yields a wrong answer.
on 7 Feb 2013
Oh, sorry, yes, I meant "diameter". I've updated the solution above to use the word "radius" and to not divide this by two.
on 7 Feb 2013
Think of it this way, when angBetweenNormVecs is very small, the cones are pointing in the same direction and are more likely to intersect. When the ang1 or ang2 of the cones gets larger, that means that the cones are covering more space, and are similarly more likely to intersect. The greater-than sign is pointing the right way, and I'm quite confident that the above algorithm works correctly.
Anyway, it will always be better to show a specific example (with code to set up your zVecs/hts/wdths) rather than say that random samples don't work...
Thanks, Sven.

Clues and hints about the 19th Century lifestyle of Governor James Stirling and his cohorts have been literally dug up beneath the green grass of an old farm in Albany.
Archaeology students from the University of Western Australia have been on an extensive dig under the grounds of Old Farm, Strawberry Hill in Albany - the first ever farm in the colony of WA - established in 1827.
Student Corey Walsh said the search for clues is proving to be more involved than a simple dig.
"No it's not just a dig we're actually looking for evidence of the wall that used to make up governor Stirling's residence while he stayed here.
'We're also just he to get an understanding of how the Spencer family and the Bird family existed and lived here on site.

Leading question
Leading question,
Definition of Leading question:
 1. A question that prompts or encourages the desired answer.
 2. Legal: In witness examination, leading questions are those that try to stack the deck of evidence one way or the other by putting words in the witness mouth. Such questions are usually not allowed in the direct examination of the witness, but are generally permissible in cross examination or where the subject matter has already been put in evidence by the other side.
 3. Market research: Query that uses emotionally loaded (prodding) words, and usually elicits a predictable Yes or No answer from a respondent in a survey. Statistical results based on leading questions are prone to give an unrealistic picture of the consumer opinions or trends.
How to use Leading question in a sentence?
 1. When the attorney attempted to solicit a specific answer from his client via the substance of his question, the opposing counsel objected that the attorney had posed a leading question.
 2. You need to try and figure out where someone is trying to take you any time they ask you a leading question.
 3. After a few leading questions about his earlier life, he talked almost nonstop.
 4. The leading question was a form of bait that the witness ate hook line and sinker as the prosecutions plan worked well.

The reason for using a hood is to block light rays from elements outside of the actual frame (stray light) to enter into the lens and degrade the image quality (lowering contrast). Effectively, it "shades" the lens from these rays. Since a sensor is rectangular, valid light rays that fall on the corners arrive from angles larger than light rays that fall on the middle of the sensor's edge. This is why many hoods have the "petal" form. Otherwise you will suffer from either vignetting at the frame corners, or lower effectiveness in blocking invalid rays.
With increasing focal length, the petal shape becomes less required and there is a transition to circular shape. Another reason for circular hoods is rotating front elements of the lens, where the hood is mounted. When focusing, the element (and hood) rotates so if you use petal hood it will lose its alignment with the sensor.

Home Heritage Useful Scots words Useful Scots word: peelie-wally
Useful Scots word: peelie-wally
by Betty Kirkpatrick
Picture: paukrus

Many of us who have a Celtic genetic inheritance have very fair skins. Usually this creates no problems and a fair skin can be a decided beauty asset. Pale skin looks fine against a background of its native heath, but transfer it to a sun-baked foreign beach and things change dramatically. Pale skin can stand out like an unfortunate sore thumb when surrounded by a sea of bronzed bodies. The Scots word peelie-wally springs to mind.
Peelie-wally, also spelt peelie-wallie and with wally pronounced to rhyme with sally, can mean pale, but in this sense it is far from being a compliment. You might describe a flawless porcelain complexion as pale, but you are very unlikely to describe it as peelie-wally. Rather, peelie-wally means pallid or washed-out looking, like the odd pale body among a multitude of sun-tanned ones.
Peelie-wally is often used to refer to the kind of paleness that accompanies ill health. If a child is looking peelie-wally it is often a sign of impending sickness of some kind. In fact, peelie-wally can mean ill-looking or sickly or, by extension, thin or feeble.
Things as well as people can be described as peelie-wally when something colourless or insipid is being referred to. For example, you might refer to the beige décor of someone's house as peelie-wally if you are the sort of person who prefers strong colours. Or you might criticize the pastel colours of someone's dress as being too peelie-wally. If you like a strong cup of tea you might describe a weaker form of the beverage as peelie-wally.
An activity or performance of some kind can also be referred to as peelie-wally when it lacks vigour or vitality. Not surprisingly, this use usually occurs in connection with Scotland's obsession with football. Apparently there are many instances of peelie-wally performances on the pitch.
The expression peelie-wally started life out simply as peelie. This is likely to have a connection with the Scots word palie meaning sickly, listless, delicate or stunted in growth and palie is, in turn, likely to be connected with English pale.
However, it has been suggested that the origin of the peelie of peelie-wally may be imitative of a kind of whining, feeble noise made by people who are ill. As for the wally, it may just have been added for effect and may have been influenced by the Scots word paewae meaning pallid, sickly or insipid. The suggestion that there is a connection with the whiteness of wallie, meaning china or porcelain, seems less likely.
But back to our sun-baked beach. There is good news for the peelie-wally. Now that over-exposure to the sun is known to cause major skin problems, official health advice is to cover up in the sun. There is now no need to reveal yourself in all your peelie-wally glory on the beach. In any case, the peelie-wally skin does not bronze. It just goes an unattractive shade of red.

 A've heard tell that in India "peelah wallah" (no shair aboot the spellin) means "pale man" an wis yaised tae descrive a body that wis no weel an the expression wis brocht hame bi Scottish sodgers as "peelie-wally".
 - Ostrakon
 You may be on to something…the expression is Pilau Wallah, used by Indians for a white or yellow coloured man.
 I suppose it would all come down to the first recorded usage of the expression Peely-Wally and whether it preceded the addition of the Indian subcontinent to the British Empire

 Thank you Betty Kirkpatrick for a consistently informative and witty column on Scots words. As one educated in Scottish schools that frowned on the use of the "mither tongue" as coarse, I am delighted to savour the flavour of Scots as it is still spoken. The column on "peely-wally" filled me with the glow of approval. Theresa McCardle

Boards and Institutional Diversity: Missed Opportunities, Points of Leverage
Since the financial crisis of 2008, board agendas have been dominated by financial and enrollment concerns. Yet boards can also play a key role in addressing issues of diversity, equity and inclusion on campus.
Given the many points of leverage they can apply, boards are uniquely positioned to advance change in ways other institutional stakeholders cannot. This paper explores how boards and institutional leaders can forge a tighter link between governance and campus diversity, one that leads to positive progress on a difficult and nuanced set of issues.
The authors based their report on personal observations and a detailed examination of the literature on board governance and campus diversity.

Olympic National Park Asked to Buy Out Mining Claims
 Olympic National Park continues to remain in the news over land-management issues. Earlier this fall the park made headlines when an Indian tribe closed access to a national park trail and a beach within the park in protest over stalled negotiations to find land that could accommodate the tribe's village, which is in a tsunami zone.
 Now three brothers who own rights to deposits of gold, platinum, oil and natural gas beneath the park's Shi Shi Beach are threatening to sell those rights to mining interests unless the National Park Service agrees to buy them for $30 million. An agent for the family told the Seattle Post-Intelligencer that the mineral deposits and oil and gas are worth a combined $2 billion.
 Park officials, whose total budget for 2004 amounted to just $10 million, say they are trying to determine the value of the claims that the brothers' grandfather bought in 1928.

Appliance and Equipment Performance with Hydrogen-Enriched Natural Gases

Executive Summary
Mixing of hydrogen into natural gas, as a means of mitigating environmental concerns associated with the use of fossil fuels, poses a question of performance of appliances designed for use with natural gas, when fuelled by blends of hydrogen and natural gas. This study examines the performance of space and water heating appliances fuelled by methane as a natural gas proxy, and methane/hydrogen blends containing up to 15% hydrogen. The appliances were tested for input rate, ignition and burner operating characteristics, combustion products properties, and gas leakage, using three gas mixtures (pure methane, 5% hydrogen/methane blend, and 15% hydrogen/methane blend mixtures) per applicable CSA/ANSI Z21 series Standards. Effects of gas composition on furnaces were also tested for temperature rise and heating tube temperatures. Condensing appliances were additionally assessed for dew point temperatures and acidity. Overall, appliances showed no major operable issues and consistent trends of decreased heat output and CO2 emissions with increase of hydrogen content in methane/hydrogen blends. Consequently, to meet the same heat demand, the appliances would need to operate for longer periods which would result in additional carbon dioxide emissions. However, the overall CO2 emissions for the same heat output are still expected to be lower with the use of blends compared to natural gas. Carbon monoxide and nitrogen oxide measurements were in the acceptable ranges regardless of the type of fuel used. No consistent trends were observed for other measured properties, indicating that hydrogen mixtures up to 15% do not significantly affect these parameters. Future testing of gas blends containing 5% and 15% of hydrogen as examined herein, as well as higher hydrogen amounts, ought to incorporate natural gases to determine more representative results.

Tanya shares the Mirror stamping technique with us today, combined with Chameleon pens.
By Tanya Batrak
Tanya explains her inspiration for this technique" I like that Chameleon pens can draw on different surfaces, and vellum is one of them. This ability will help you if you want to try a mirror stamping technique."
Materials Used: Chameleon Color Tones Deluxe Set; Warm Sunset (YO3); Olive Green (OL3); Deep Violet (VO4); floral stamp; watercolor paper; American Crafts ribbon.
- Stamp image several times on a scrap piece of paper to make a border. If you are happy with the result, now you can proceed on a card.
- Make 4 ¼ x 7"card from card stock.
- Draw a horizontal line with the pencil to divide the front side of a card in two.
- Stamp image several times over the pencil line to make a border.
- Color each image with the brush tip using Warm Sunset, Olive Green and Deep Violet infusing each color before coloring for 3 seconds.
- Cut a piece of vellum (3x7").
- Stamp the same image several times on a piece of vellum.
- Flip the vellum and you will see that the images now look down.
- Color each image on a vellum with the brush tip using Warm Sunset and Olive Green infusing each color before coloring for 3 seconds.
- Die cut the flower petals or cut them with scissors. Color each petal with the brush tip using Deep Violet infusing the color before coloring for 5 seconds. Add strokes with the same color with the bullet tip. Adhere all petals together. Color the center of a flower with Warm Sunset and adhere it on the flower.
- Adhere vellum, ribbon, flower and two petals on a card base.
This is such a great way to reverse the image of a stamp to get a mirrored effect, we will be bringing you more techniques soon from the team so do pop back soon!

I need to show specifically using transfinite induction that given two well-ordered sets $\left(A,<_{1}\right)$ and $\left(B,<_{2}\right)$ there is only one isomorphism between them. To do this I want to show by induction that there is only one way to define the mapping and that is: $$\forall\, x\in A: \varphi\left(x\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Showing the base of the induction is no problem and the induction hypothesis would be that $$\forall\, y<_{1}x\,:\,\varphi\left(y\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}y\right\} \right)\right)$$ My problem is that I can't seem to manage to use the hypothesis in order to prove the step. I've found a couple of ways to show this definition of the mapping is indeed necessary but none of those used the induction hypothesis. My plan was to mark $$c_{0}=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Using the fact $\varphi$ is surjective take $y\in A$ such that $\varphi\left(y\right)=c_{0}$ and show that it can't be that $y<_{1}x$ or $x<_{1}y$ and thus necessarily $y=x$. If someone could give me a way to show either one of these are false using the induction hypothesis it would solve my problem.
Thanks a lot!

What you want to show is that if $f\colon A\to B$ is an isomorphism of the given well-orders then $f=\varphi$.
Suppose that for $x\in A$ we have that $f\upharpoonright\{a\in A\mid a<_1 x\}=\varphi\upharpoonright\{a\in A\mid a<_1 x\}$. If $f(x)=\varphi(x)$ then we may continue the induction; otherwise $\varphi(x)


TIFF Compression and Fill Order
The TIFF compression options allow you to select the specific compression methods to use on different types of outputted TIFF image files.
TIFF Compression
The Advanced Monochrome option (sometimes also known as fill order) allows you to select the order in which bits are stored within a byte when writing image data to the file. This option is used generally with fax format TIFF files.
Fill MSB to LSB - When storing in most significant bit to least significant bit (MSB to LSB) fill order, bits are stored starting at the high-order bit of each byte, with successive bits stored at the next-highest bit until the byte is filled.
Fill LSB to MSB - when storing in LSB to MSB fill order, bits are stored in reverse, starting at the low-order bit of each byte. LSB to MSB fill order is recommended only when dealing with black and white images, and with the CCITT Group 3 1D compression method.

Parameter Sweep
Parameter Sweep is an advanced technique in electronic design used to evaluate and optimize circuit performance at varying values of component parameters.
30. June 2023
3 minutes reading
Definition
Parameter Sweep is an advanced technique in electronic design used to evaluate and analyze the circuit's response at varying values of one or more component parameters. By performing this type of sweep, one can systematically change the parameter settings and observe the effect on circuit performance to identify optimal operating conditions and achieve desired results.
Purpose of running a Parameter Sweep
Parameter Sweep plays a crucial role in electronic design and analysis. By running it, the following objectives can be achieved:
 1. Circuit design optimization
 Parameter Sweep enables the evaluation of circuit performance at different settings of component parameters. This allows for the identification of optimal values and adjustments to the design to achieve desired functionality, stability, and efficiency.
 2. Troubleshooting and diagnostics
 Parameter Sweep helps identify potential issues and errors in a circuit. By varying the component parameters, one can observe how the circuit response changes and identify the causes of errors or undesired behavior.
 3. Design process optimization
 Performing a Parameter Sweep can expedite the design process by identifying optimal parameter settings early in the development phase. This minimizes the need for iterative loops and saves time and resources.
Parameter Sweep
Implementation
To perform a Parameter Sweep, you select one or more component parameters to be evaluated and define a set of values for these parameters to vary between. Subsequently, simulations or physical measurements are performed on the circuit for each combination of parameter values to obtain a comprehensive set of results that can be analyzed and compared.
 1. Design your circuit: Begin by building your electronic circuit using a schematic design tool. Add the necessary components such as resistors, capacitors, inductors, active components, etc. Also, define the parameters you wish to vary in the parameter sweep.
 2. Identify parameters: Choose the circuit parameters you want to vary, such as resistor values, capacitor capacitances, voltage levels, frequencies, etc. These parameters can be specific values you want to test or a range of values within an interval.
 3. Configure the parameter sweep: Set up the sweep in your simulation tool. Specify the values or interval you want to vary the parameters within and define the number of steps or interval size between the values.
 4. Define results: Identify the output parameters you want to observe as a response to the parameter sweep. This may include voltages, currents, power, or other circuit characteristics relevant to your analysis.
 5. Perform the simulation: Initiate the sweep simulation. The simulator will now perform multiple simulations with different values of the selected parameters and record the results for each combination.
 6. Analyze results: After the simulation is completed, you can analyze the results. This typically involves studying graphs showing how the output parameters vary with the changed parameter values. You can identify patterns, draw conclusions, and gain a deeper understanding of how the circuit responds to different parameter values.
A parameter sweep enables you to explore various aspects of your circuit, optimize its performance, and understand how different parameters affect its behavior.
Advantages
Parameter Sweep brings several benefits to electronic design and analysis:
 - Optimal performance
 By performing a Parameter Sweep, one can identify the optimal settings of component parameters that result in maximum performance for a given circuit. This enables design optimization and ensures efficient circuit operation under different operating conditions.
 - Error identification
 By varying the component parameters in a Parameter Sweep, changes in circuit response can be observed, allowing for the identification of potential errors or problematic areas. This enables error correction and improves the circuit's reliability and quality.
 - Time savings
 Parameter Sweep can help reduce time consumption in the design process by identifying optimal parameter values early in the development phase. By reducing the need for experimental iterations and trial-and-error methods, the sweep accelerates the design process and increases productivity.
 - Optimized design process
 Performing a Parameter Sweep can lead to a deeper understanding of circuit behavior under varying parameter values. This can result in more sophisticated and well-balanced design solutions that meet specific requirements and preferences.
Parameter Sweep is a powerful technique in electronic design that enables optimization of circuit performance, error identification, and time savings in the design process. By systematically varying the component parameters, optimal settings can be achieved, ensuring maximum performance and reliability for electronic circuits. It is an invaluable tool for electronic engineers seeking to deliver quality designs in less time.

text: AbstractGrass-lined spillways are flow conveyance structures with environmental benefits. The stability of such spillways has been typically assessed considering soil erosion, but the design of grass-lined spillways based on hydraulic considerations has rarely been conducted. While subcritical flows in channels with grass have been studied extensively, studies of velocities and flow resistance in supercritical flows in spillways are limited. Herein, this experimental study investigated the application of a multilayer velocity model for supercritical self-aerated flows on a spillway with submerged artificial grass. Velocities were measured with a pitot tube and dual-tip air–water flow conductivity probe, providing the most systematic assessment of velocities and flow resistance in supercritical vegetated flows to date. The velocity distributions were well described with a multilayer velocity model previously developed for subcritical flow conditions, and a constant interfacial velocity supplemented the observed supercritical aerated free-surface layer. Based on this velocity model, explicit expressions for the mean flow velocity and the friction factor were developed for grass-lined spillways, which were also applicable for subcritical flow conditions with comparable vegetation cover. The flow resistance model provides a theoretically developed design option for grass-lined spillways that is solely based on vegetation properties and hydraulic boundary conditions.

Brazil scientists find signs of underground river
SAO PAULO (AP)? Brazilian scientists say they have found signs of a huge underground river flowing far beneath the Amazon River.
Valiya Hamza of Brazil's National Observatory says there are indications of a 3,700-mile (6,000-kilometer) long subterranean river located several thousand feet below the surface.
Hamza says the finding came from studying temperature variations at 241 inactive oil wells drilled in the 1970s and 1980s by Brazil's state-run oil company.
Hamza says the thermal information allowed his team of researchers to identify the movement of water 13,100 feet (4,000 meters) under the Amazon River.

Theory of timber connections with slender dowel type fasteners
- Svensson, Staffan, Munch-Andersen, Jørgen
- Wood material science and engineering 2018 v.13 no.1 pp. 7-15
- equations, fasteners, materials science, models, prediction, wood
- A theory on the lateral load-carrying capacity of timber connections with slender fasteners is presented. The base of the theory is the coupled mechanical phenomena acting in the connection, while the wood and the slender fastener deform and yield prior to failure. The objective is to derive a sufficient description of actions and responses which have determining influence on the load-carrying capacity of timber connections with slender fasteners. Model assumptions are discussed and made, but simplifications are left out. Even so, simple mathematical equations describing the lateral capacity are derived from mechanical equilibrium of the deformed fastener. The herein proposed theory is verified against tests. The tests were designed to vary the influence of isolated mechanical phenomenon as much as possible. The theory shows a very high accuracy and precision when predicting the load-carrying capacity of the tested connections.
