and if you Do have the subscription object, update your server database with the latest subscription object. The ready property of the service worker defines whether a service worker is ready to control the page or not.
It returns a promise which resolves to a serviceworker registration object. When the service worker becomes active, the get subscription function returns the subscription object or undefined. If it doesn't exist, we need to perform this check every time. The user accesses our app because it is possible for subscription objects to change during their lifetime. This is the process of subscribing to the push service register, the service worker from the main page main jeaious.
This request goes to the user agent. The user agent returns the service worker registration, object, use the service worker at registration, object to access the push manager API and from that requests are subscribed to the push service. This request is passed on to the push service. The push service returns. The subscription object, which includes the endpoint URL and the public key, save the subscription object data to your server and send push messages from your server to the endpoint URL encrypted with the public key.
Like I said now before sending notifications, we must subscribe to a push service. We call push manager subscribe on the service worker registration object to subscribe and the resulting push subscription object includes all the information. The application needs to send a push me such an endpoint and encryption key needed for sending data each subscription is unique to a service worker. The end point for the subscription is a unique capability.
Url knowledge of the endpoint is all that is necessary to send a message to your application. The endpoint URL therefore needs to be kept secret or other applications might be able to send push messages to your application. Here's an example of the subscription object. This is the object returned from the push service. When we call reg push manage, add subscribe. The subscription object has two parts.
The first part is an endpoint URL. The address on the push service to send messages to this includes an ID that enables the push service to send a message to the correct client and service worker. The second part of the subscription object is the keys property. The p25 6d H key is an elliptic curve, diffie-hellman ECD H public key for message. Encryption. The earth key is an authentication secret that your application server uses in authentication of its messages.
These keys are used by your application, server to encrypt and authenticate messages for the push subscription and, let's see how the process of sending a message is done. The server generates a message encrypted with the public key and then sends it to the endpoint URL in the subscription object. The URL contains the address of the push service along with subscription ID, which allows the push service to identify the client to receive the message.
The message is received in the push service which routed to the right, client and the process of sending a push message from the server works. Like this. A back-end service on your server sends a push message to the push service using the endpoint URL from the subscription object. The message must be encrypted with the public key from the subscription object. The push service uses subscription IDs encoded in the endpoint URL, to send the message to the right user agent.
The push event is picked up by the service worker. The service worker gets the data from the message and displays a notification in this example. We're using Google's web push library for nodejs to send a push message from a node.Js server. The TTL value in the options specifies the time in seconds that the push service should keep trying to deliver the message now. This is important to set correctly some messages.
Have a short life some may be valid for several hours or more. We then pass in the subscription object. Payload and options object to send notification. You need a way to ensure secure communication between the user and your server and between your server and the push service and between the push service and the user. In other words, the user needs to be sure that messages are from the domain. They claim to be from and have not been tampered with by the push service you need to make sure the user is who they claim to be valid, was created to solve this problem.
This vapid identification information can be used by the push service to attribute requests that are made by the same application server to a single entity. This can be used to reduce the secrecy for push subscription URLs by being able to restrict subscriptions to a specific application server. An application server is further able to include additional information. The operator of a push service can use to contact the operator of the application server in order to use vapid, we need to generate a public/private key pair and subscribe to the push service using the public key.
The public key must be first converted from URL base64 to a you in 8 array. This is then passed into the application. Server key parameter in the subscribed method. The web push library, provides a method generate vapid keys, which generates the keys. This should be used once in the command line when push generate vapid, keys, Jason and the keys stored somewhere safe. We can use the web push library to send a message with the required vapid details.
We add a vapid details, object in the options parameter. That includes the parameter required for the request signing now. Let's look at messages from the receiving end in the web. App on the client handling push, events happens in the surface worker, the service worker will be woken up to handle incoming push messages and a push event is fired. This allows your app to react to push messages, for example, by displaying a notification using service worker registration, show notification to display a push notification.
You listen for the push event in the service worker. You get the push message. Data from the push event object in this example, we simply convert the message: data to text The Wrap, show notification in a wait until to extend the lifetime of the push event. Until the show notification promise resolves, the push event will not be reported as successfully completed until the notification has displayed.
You can practice working with the notification and the push API by following the lab that accompanies this article, one small gotcha, don't use private or incognito mode for this lab for security reasons, push notifications are not supported in private or incognito mode. You

Web Payments (Chrome Dev Summit 2016)
But if you think registration forms are difficult, we should talk about. Checkout forms a lot more form fields, a lot more questions, but I think that you're going to see a consistent theme emerging through, like our talks here today, which is this one of let the browser help you. There are certain advantages that we have as a browser, especially when it comes to reducing friction and making life easier for users, especially things around repetitive data steps, things that the users can store inside of the browser's, but we're trying to do our expose api's and give You tools to reduce, friction and make things easier for your users.
We saw it in Koreans, while management and we'll see a very similar theme with what we're doing in payments, but first a little user activity just before we go off for lunch, which are some questions. Okay, great so first question just curious: how many people here actually enjoy the process of buying something on the web using their mobile device? Okay, good yeah and some people, but by large? No and whether we should come talk.
I'd love to hear like what is that you'd like about buying things on the mobile web and what it is that you don't as much a second question, and I would be really impressed here how many people can remember all the details of their credit card. I'r talking full 60 digit number really CVC on expiration. Okay, it's more than I expected. I got to be honest, like okay, we're still like under 15 %, but okay cuz I've even payments out for like 18 months, and I think I have yet to remember a credit card number, that's great and then okay final question: how many people enjoy the process Of handing over all their sensitive credit card information to a random third party server I'll get one.
It's almost like. I'r asking these questions to lead up to a particular point, and – and there was a points and the reality is that most users finds payment difficult. They find it insecure and scary and frightening and they find the process of doing it on the mobile web, particularly bad, and so we had this number. We talked about it at i/o as well, and it hasn't really changed, which is that on average, we tend to see about 66 percent fewer conversions on mobile than on desktop and again we think there's an answer to that, which is all around again high.
Friction the difficulty and issues around trustworthiness and security, and so we'll talk about sort of how we're addressing those today and how we're trying to bring fast, simple and secure payments to the web platform. But this is a little I'm a p.M. It's a little bit too PME for me actually, and so I have a much better mission for us inside of the chrome team, which is we're trying to save the world from annoying check out forms.
So I'm trying to save the world from virtual keyboards and having to memorize and all of those terrible things. I actually started this joke of the better payments Bureau a couple of months ago, and now it's become like a thing so anyway, but actually Chrome has been fighting the good fight against annoying check out forms for many years. Actually, we start with autofill back in the day, you guys are probably familiar with autofill.

Types of Rail
The Passenger Rail Study between Tucson and Phoenix is looking to connect the two largest metropolitan areas in Arizona and provide intercity/commuter rail transit. Rail in Arizona is growing. The light rail system in Maricopa County started operating in 2008 and the Modern Street Car in Tucson is set to open in 2014. Arizona continues to study and develop future rail in Arizona.
What is the difference between different types of rail?
Passenger rail can shape a community. The studies below help answer a few questions: How can we better design various transportation modes to function together, creating a fully integrated and more intelligent system of transportation? Is it important that we find alternative fuel courses and reduce energy consumption for transportation?
Additionally, how can passenger rail shape communities, enhance economic vitality and improve the quality of life? What kind of systems are operating in the Western United States? Part of this study includes the development of station area planning guidelines that would be made available to surrounding communities.

The system characteristics show the pressure loss in the system as a function of the flow
The system characteristics show the pressure lost in the system as a function of the flow. The starting point of the characteristics depends on the type of system.
a. In a closed system (circulation of liquid) it will always start at 0.0 (0 flow; 0 head).
b. In an open system (transport of liquid) the starting point depends on the Hgeo (geometric lift).
For all system characteristics apply that there is a connection between Q (flow) and H (head). If Q is reduced to 1⁄2, H will be reduced to 1⁄4.

It can be observed that radius (r) of the cylindrical part and the hemispherical part is the same (i.e., 7 cm).
Height of hemispherical part = Radius = 7 cm
Height of cylindrical part (h) = 13 −7 = 6 cm
Inner surface area of the vessel = CSA of cylindrical part + CSA of hemispherical part
= 2 πrh + 2π r2
Inner surface area of vessel
= 2 x 22/7 x 7 x 6 +2 x 22/7 x 7
= 44(6+7)
= 44 x 13
= 572 cm2

Flow rates through Sturgeon Lake and backwater channels of the Mississippi River in the vicinity of the Prairie Island Nuclear power Generating Plant are determined as a function of total river flow and of wind direction and wind velocity, particularly for low flow conditions. The analysis is made in order to determine; (a) how much of the Sturgeon Lake flow is drawn into the cooling water intake of the plant, and (b) by how much plant effluent cooling water or blow down water is diluted by sturgeon Lake effluent before entering the Mississippi River. A channel network analysis including effects of wind stress on the water surface in addition to bed shear stress and local (minor) energy losses was made to provide the required information. Forty-three channel and channel segments were used to describe the entire system. The Sturgeon Lake/North Lake system was studied before the complete analysis was made. In the absence of wind, flow through Sturgeon Lake amounted to about 22 percent of total river flow. At low plant withdrawal rates and at zero wind, the flow through the backwater channel in front of the plant outlet (channel 42) was about 10 percent of total river flow. Winds from 5 to 30 mph had a very noticeable effect on flows through Sturgeon Lake, particularly when total river flows were less than 10,000 cfs. The analysis was made without consideration of stratification effects near the plant intake and outlet.

I am looking for methods that take into account rotation as well as translation for continuous collision detection.
My broad phase algorithm uses swept maximal bounding spheres returning a start time when the objects will be within their maximum radius.
I have two ideas how to handle the next phase of collision detection:
1 ignore rotation:
A simplified collision I am considering is to ignore rotation from the beginning of the narrow phase and use a GJK representation to raycast the relative motion of the objects to the origin. This should give an intersection time by a raycast against a convex hull. This method will result in colliding objects to stop rotating for a portion of the time step, and can miss collision due to rotation over the timestep.
2 bisection search:
Doing a bisection search of instantaneous GJK tests at increasingly smaller intervals, presumably down to a fixed size. If a collision is detected then only earlier points in the bisection need be considered (reducing the search space), but to rule out collision completely the full space needs to be searched. This seems fairly expensive and can still miss collisions where the periodicity of motion is between the test points.
I have found some indication that dual numbers or dual quaternions + screw theory may have some application but it seems like an advanced topic and so far the only game-related application I have found is in mesh deformation, not collision detection. Screw theory seems promising, but I'm not sure it applies to situations where the axis of rotation is not the same as the axis of translation, or if that is just a sub-set of certain screw motions.
Some possible resources:

Inside-Out, Outside-In
There are two common perspectives on the process of architectural design, whether it be for buildings or for software. The first is that a designer starts with nothing—a blank slate, whiteboard, or drawing board—and builds-up an architecture from familiar components until it satisfies the needs of the intended system. The second is that a designer starts with the system needs as a whole, without constraints, and then incrementally identifies and applies constraints to elements of the system in order to differentiate the design space and allow the forces that influence system behavior to flow naturally, in harmony with the system. Where the first emphasizes creativity and unbounded vision, the second emphasizes restraint and understanding of the system context. – "RESTful" Roy Fielding
It might not be a correct interpretation, but BD00 associates Mr. Fielding's two alternatives with "inside-out" and "outside-in" design.
The figure below illustrates the process of inside-out design. The designer iteratively composes a structure and "hopes" it will integrate smoothly downstream into the context for which it is intended. During the inside-out design process, the parts are king and the system context is secondary.
Parts First
The figure below depicts an outside-in design process. The designer iteratively composes a structure within the bounded constraints of the context (the "whole") for which it is intended. During the outside-in design process, system context is king and the parts are secondary.
Context First
Because system contexts can vary widely from system to system and they're usually vaguely defined, messy, and underspecified, designers often opt for the faster inside-out approach. BD00 uses the outside-in design process. What process do you use?

What does the world look like through the eyes of a mantis shrimp? It's not a question most of us would think to ask, but a new study has given us the answer: It looks like nothing humans (or any other animals) have ever seen.
It turns out that these exotic sea critters—affectionately known to the researchers in the study as "shrimp from Mars"—can see a kind of light that, as far as we know, is not apparent to any other animal on the planet. Not only that, but certain parts of the shrimps' bodies can reflect the same kind of light, creating a signal only other mantis shrimp can see. Thanks to this phenomenon, the creatures have their own visual code—a completely private way to communicate with one another as they scuttle across the ocean floor.
A research team well versed in the ways of mantis shrimp was tipped off by a set of unusual structures within the animals' eyes. These structures use the same principles as man-made detectors built to sense circularly polarized light—a specialized kind of light used to reduce the glare off computer monitors and take clearer photographs. When the researchers poked tiny electrodes into the shrimps' eyes and directed circularly polarized light onto them, they found that the same cells responded in different ways, at times recognizing the properties of circularly polarized light.
As for what one mantis shrimp looks like to another, Tom Cronin, a biologist at the University of Maryland Baltimore County and one of the study's authors, says that "it's impossible to know."

Google spots DDR4 weakness that could expose your PC to a system takeover
Google spots DDR4 weakness that could expose your PC to a system takeover, A new DRAM hacking technique might expose your DDR4 RAM to assaults and eventual system takeovers. Fortunately, Google is stepping up with the wise notion of making the findings public in the hopes of hastening a repair.
The software is a new variant of a known vulnerability called Rowhammer. The vanilla version of the software would compromise the data rattling around your RAM's memory cells by granting hackers ability to access one adjacent row, and modify the content of other memory addresses, by sending multiple access requests.
It's existed for a while and, according to Neowin, it came about thanks to an "electrical coupling phenomenon in silicon chips which bypasses software- and hardware-based protection."
Previously, DRAM makers could safeguard against Rowhammer attacks by installing circuitry that detected and blocked the nefarious behavior in DDR3 chips. They assumed it was all over. However, with the introduction of DDR4, it has been shown that the curse of Rowhammer is still a menace, operating via TRRespass and other techniques.

Where it all began
MAF began with some World War II pilots who had a vision to help those in need. The idea was to use planes positively to spread the peace of God – rather than negatively to spread the conflict of man. After the war, Murray Kendon, Stuart King and Jack Hemmings worked with the Mildmay Movement to raise the funds required to realise their vision.
In 1948, the first survey flight of Africa was completed and Sudan identified as a country with need of an aircraft to help further the gospel. In 1950, the first MAF base started in Akobo, Sudan. At the same time, similarly minded Christian pilots started missionary organisations in the US and Australia, eventually also becoming known as MAF. Able to provide medevacs to missionaries in remote areas and help reach the isolated communities, the visions of those early pioneers became a reality. Within 15 years, there were operational bases opened in Sudan, Mexico, Papua New Guinea, Indonesia, Ecuador, Kenya and Ethiopia.
What started off as the dream of a few Christian air force pilots is now a global movement with around 123 aircraft serving in over 25 countries worldwide. Tens of thousands of remote communities now have access to healthcare, education, community development, disaster relief and the Good News of Jesus Christ.
A lot has happened over the 70 years since MAF was formed, but through the change, through all the developments in technology and aviation practices, the heart of MAF has stayed the same: to see isolated people changed by the love of Christ through serving together to bring help, hope and healing through aviation.

How to Prep Vegetables with a Food Processor
While we definitely think that home cooks should develop their knife skills, we can all use a little assist in the ingredient prep stage of a recipe, especially when we have to chop, dice, slice, and/or shred our way through a laundry list of components.
The detailed lineup of ingredients in many vegetable-centric main dishes can make these recipes seem intimidating, and often different vegetables need to be prepared in different ways. Luckily, a good food processor permits you to put down your knives (and your mandoline and your grater)—the food processor will act as your prep cook. You'll get more uniform results while saving time, energy, and your sanity.
Here are a few tricks we've discovered for making vegetable (and other ingredient) prep easier in the food processor:
1. The Slicing Disk Is Your Best Friend
Some food processors have adjustable blades so you can change the thickness of the slices. You can also purchase smaller or larger slicing disks for most models. The way you feed ingredients into the processor affects the slices, so pay attention to the orientation of the ingredient in the feed tube. Slicing works best with firm ingredients, so we prefer tightly packed greens, like the heart of romaine (see below). You can also roll greens like kale to create a tightly packed bundle for slicing.
Slicing Romaine with food processor
2. Choose the Right Feed Tube
Many food processors come with a small and large feed tube. Choosing the appropriate size for your ingredients will help you pack them tightly; you'll get cleaner, more consistent results if they don't have room to move around. Whole potatoes, onions, and big pieces like wedges of cabbage benefit from the larger tube, while smaller amounts of narrower carrots, zucchini, and celery work best in the smaller one.
3. When In Doubt, Underprocess
Our best advice for chopping in the processor is to err on the side of underprocessing—you can always give the ingredients another pulse to chop them more finely, but you can't go back. For this precise reason, we tend to use the pulse function instead of the processing function when chopping, grinding, or mincing ingredients in the food processor. Pulsing food offers more control than processing it; the food is chopped more evenly because the ingredients are redistributed—akin to stirring—with every pulse. This allows you more control over the final texture, as with something like Cauliflower Rice.
Processing cauliflower in the food processor
4. Trim the Ingredients and Use Steady Pressure
Depending on the size of your ingredient, you may need to do some trimming before placing it in the feed tube. Use steady pressure when pushing food through the tube into the blades. If you're slicing several different ingredients that will ultimately be combined, you can even put them all into the feed tube together.
5. Shredding Disk Easy Cleaning
The shredding disk can shred all kinds of ingredients into small, even pieces. You can power through pounds of potatoes and other firm ingredients (like carrots) in just seconds. To make cleanup easier, spray the feed tube, disk, and workbowl with a light coating of vegetable oil spray before you begin to keep the ingredients from gumming up the shredding disk.

An ideal solution or ideal mixture is a solution in which the enthalpy of solution is zero ΔHsolution = 0; the closer to zero the enthalpy of solution, the more "ideal" the behavior of the solution becomes. An ideal mixture is one in which the activity coefficients are equal to one. The concept of an ideal solution is fundamental to chemical thermodynamics and its applications, such as the use of colligative properties. Since the enthalpy of mixing (solution) is zero, the change in Gibbs free energy on mixing is determined solely by the entropy of mixing.

Have you ever been compelled to leave your country for another due to your home country's hostile living conditions? If you have gone through that experience, then that is what Moroccans are going through in their homeland. They are leaving their country for other nations because of the harsh conditions in Morocco. Leaving your homeland due to poor residential situation is an experience you should never long to meet in your life. It encompasses challenges that pose risks to your life through exposure to fatal dwelling conditions and deficiency of basic needs. Leaving your nation may emanate for several reasons, and this explanation seeks to identify why Moroccans are fleeing Morocco.
There are varied reasons that compel Moroccans to move out of their land and settle in other parts of the world. These migrants target finding better residential areas that can help these Moroccans evade the harsh lives in Morocco. The poverty level is one of the major reasons that make Moroccans flee their motherland. It is because the living conditions in Morocco cannot allow them to continue residing in those areas. They are unable to meet their basic needs as they languish in hunger caused by increased poverty levels. Because of the strife caused by poverty, these citizens resort to other areas to have better lives and meet their needs.
Natural calamities explain why Moroccans are fleeing their land. On many occasions, these citizens confront calamities that impede their lifestyles in their homeland. For instance, many areas in Morocco are common to floods making life in those areas unbearable. These floods displace the citizens causing them to miss shelters. The floods have the effect of destroying property, making them lose their valuables, a condition that continues to worsen their lives. Famine is another calamity that affects the Moroccans making them move out of their realm.
Cultural influence is a vital factor that explains the increased instances of the Moroccans running away from their realm. This aspect is common among the young Moroccans who find it difficult to maintain their cultural practice. They have succumbed to cultural influences that compel them to move out of their realm to find a better avenue for expressing their desires for a new culture. The American way of life is the primary culture that poses risks to the Moroccan culture, making young people run away from their land. In this new culture, the desire to put on suits by those young people keeps them moving out of their roots to enjoy other charming practices of the western culture.
Unpleasant political policies in Morocco define the reasons why Moroccans are fleeing their nation. This aspect significantly affects the young populations as they feel that the political parties have neglected their presence. For instance, those political parties do not give space for the youths so that they can also take an active part in the activities within the parties. State parties do not offer leadership positions or the youths' chances to contest for the executive posts with state parties' support.
Incompetent government is a factor that makes Moroccans run away from their nation. It is because their government has ignored to support them and meet their needs. For instance, they cannot get a quality education that can help them improve their skills in different professions. The government has failed to offer employment chances for the young people, making them opt for different countries to get jobs. Those citizens are also suffering since their government has been unable to offer them social amenities like healthcare services to allow them to live healthy lives and get treatments for their sickness.
Indeed, Moroccans are leaving their countries for other nations, as their home country's life is unbearable. The need to find greener pastures is their primary goal: to quench their thirst for healthy living. Primarily Moroccans are moving out of their nation due to the increased poverty levels that can allow them to continue living there. The country's economy has gone down, and the government is not ready to consider alternatives to support its citizens. Natural calamities drive people out of their country in Morocco, as the living conditions are unbearable. Political parties have failed to give a space for the youth to express their skills in leadership positions. They have faced rejection as the older people have occupied all the leadership posts.

In this figure above showing white dresses one can see the different styles, with added accessories and patterns. Using the color 5 element theory these dresses can be described as:
- Metal & Wood Pattern
- Red Belt – Fire
One can begin to be aware of the elements in the colors and shapes they are wearing and learning what accessories to use and when by becoming familiar with the qualities of the 5 elements and their cycles of harmony and disharmony.
One can also learn their primary nurturing element and begin to explore applying these principles to their wardrobe to dress for harmony and success. Using Chinese Cosmology find your Kua Number. This will give you your element and corresponding color palette. If at first you are not drawn to your elements color range explore what elements support your primary nurturing element. For example in the 5 element theory wood supports fire. If the fire range is too strong a range for you, consider the wood palette as wood supports fire!
Learning your element, one can then begin to explore the 5 element cycle of harmony or disharmony to accessorize their outfit to express the experience they are wearing. An example is in the first figure in frame one of the white dress that is in a metal color, water shape and accessorized with a red belt which reflects fire. In 5 element theory metal creates water so the style and color are in harmony yet the contrasting belt is fire which is considered to melt metal. The belt is a nice contrast for too much metal and water!

SERS substrates for sensing in pathology and physiology
Item statusRestricted Access
Embargo end date25/06/2021
Fleming, Holly Anne
Monitoring physiological parameters such as pH at the site of a disease are important in determining the health status in patients. Current approaches are based on the analysis of arterial blood to measure systemic blood pH along with other parameters such as PO2 and PCO2, to allow assessment of gaseous exchange and ventilation efficiency. There has been a drive to develop improved sensors capable of continuous and dynamic monitoring of these aspects. Optical sensing devices have gained popularity as they can be designed to incorporate inexpensive optical fibres and miniaturised and mass-produced detectors and LED-based light sources. In addition to monitoring pH in a clinical situation, the development of physiological sensing tools for use at a cellular level has been critical in being able to non-invasively assess cellular response to a host of insults be it drug treatment or other cellular modulation strategies. The move towards three-dimensional (3D) cell culture has become increasingly attractive as a mimic of the 3D architecture and gradients found in vivo. The development of spatially selective sensors capable of measuring these physiological features could provide a tool in understanding cell-drug responses. In this thesis, multiple approaches were developed to enable SERS pH sensing based on both an optical fibre as well macroscopically entrapped SERS sensors applied as a means of observing extracellular pH within a 3D cell culture system. This included the use of pH responsive reporter molecules on nanoparticles (Chapter 2), their entrapment within macro-scale supports such as polymer beads and (Chapter 3), and paper (Chapter 4).

Vegan and Cruelty-Free Korean Cosmetic Brands
Consumers are leaning towards vegan beauty brands and there are two good reasons why. The obvious reason being that vegan skincare source its ingredients from nature and are cleaner and safer for the skin. Others prefer vegan and cruelty-free products because they care about animal rights and refuse to support animal-testing.
There are brands that are vegan but not cruelty-free, and vice-versa.
- Cruelty-free simply means that the product and its ingredients have not been tested on an animal.
- Vegan means that there are no animal-derived ingredients in the product.
- Together would mean you cannot have ingredients such as honey, collagen, and snail mucin.
Being vegan is a commitment not all of us of can easily make, and the same goes for all beauty brands in the industry. It can be costly changing manufacturers and sourcing not as easily accessible ingredients. America is leading in the numbers of companies converting to vegan and cruelty-free. In South Korea, there are many vegan skincare products but only a handful of brands that can say ALL their products are vegan AND cruelty-free. Here are some of those brands:
1. Dear, Klairs
Dear, Klairs: claims to be the first vegan cosmetic brand that has been approved by the Korea Agency of Vegan Certification and Services. All products are developed without animal testing and are not exported to countries with animal-testing requirements. They've also made strides to support sustainability by partnering with eco-friendly and zero-waste businesses. Among their simple and minimal products is the Freshly Juiced Vitamin Drop. It is a Vitamin C serum that evens skin tone and brightens dull complexion. Over 2 million bottles have sold making it a global best-seller.
Purito: takes pride in safe and clean products that help your skin health in the long run. Animal testing is avoided, and a portion of profits are donated to Best Friend Animal Society. All products are free from synthetic fragrances and dyes, phenoxyethanol, and triethanolamine. The brand image and concept is green and eco-conscious, with nature at its core. Late last year, Purito was wrapped in a controversy because of the false SPF level. From my experience using the Centella Green Unscented Sunscreen, it was lightweight and did not feel sticky and uncomfortable to wear. Last month, they made a comeback with a new formula of their sunscreen that's been highly anticipated!
Beplain- is a Korean skincare brand that offers clean beauty made with natural and effective ingredients for all skin types. Keeping the ingredient list simple, products are free from paraben, phthalate, SLS, SLES, mineral oil, artificial fragrance, and colorants. Caring for your skin with harsh products is possibly worse than not having a skincare routine at all. Beplain's Greenful Ph-Balanced Cleansing Foam has received a Hwahae award in 2020 and recognition from Allure in 2019. Cleansing products that have low pH helps protect the skin barrier while clearing breakouts and unclogging pores.
It's 2021 and inevitably more consumers are more conscious of the ingredients in their products. Vegan beauty, similar to vegan diets, is increasingly becoming favorable in the beauty industry. I personally use products from all three brands but have not completely made the switch to a 100% vegan skincare routine. Are you a fan of vegan and cruelty-free cosmetic products?

The increasing complexity of power systems has warranted the development of geographically distributed real-time simulations (GD-RTS). However, the wide scale adoption of GD-RTS remains a challenge owing to the (i) limitations of state-ofthe- A rt interfaces in reproducing faster dynamics and transients, (ii) lack of an approach to ensure a successful implementation within geographically separated research infrastructures (RIs) and (iii) lack of established evidence of its appropriateness for smart grid applications. To address the limitations in reproduction of faster dynamics and transients, this study presents a synchronous reference frame interface for GD-RTS. By means of a comprehensive performance characterisation, the superior performance of the proposed interface in terms of accuracy (reduced error on average by 60% and faster settling times) and computational complexity has been established. This study further derives the transfer function models for GD-RTS with interface characteristics for analytical stability analysis that ensure stable implementations avoiding the risks associated with multiple RI implementations. Finally, to establish confidence in the proposed interface and to investigate GD-RTS applicability for real-world applications, a GD-RTS implementation between two RIs at the University of Strathclyde is realised to demonstrate inertial support within transmission network model of the Great Britain power system.

North Queensland librarian Helen Pedley says street names and the people they were named after give great insight into a town's history and development.
The Tully-based librarian has written two books using street names as the springboard for the history.
"The history of the town is laid out in the landscape," said Ms Pedley.
"That's people's addresses, that's where they live and it's a part of the history of the community," she said.
Ms Pedley's most recent book Streets by the Sea: A Cardwell Chronicle was released earlier this month with 3 Brigade's Colonel John Simeoni the guest speaker at the launch.
Ms Pedley says with the military connections of the town's namesake Edward Cardwell and many of Cardwell's streets named after former defence personnel, it was important to have a military presence at the event.
"[Edward Cardwell] had a lot to do with army reforms but also the more recent streets of Cardwell were named on the advice of the RSL to the council," she said.
During the creation of the book Ms Pedley endeavoured to use original accounts from letters or newspaper articles to distinguish it from other histories of the town.
"Premier Herbert his original letters are very interesting, he comments on Governor Bowen and his wife and those sort of comments are first-hand evidence of what the people were like who have streets named after them.
"A sort of Facebook only 1864 style," she said.

How to Safely Solder Joints onto Piezo Transducers
Share This
Share This
When working with piezos, soldering is a skill that must be mastered. So what is soldering? Soldering is the the process of fusing different types of metals together by melting solder using a hot iron. This process creates a permanent connection between the different components.
In this post, I'll give you an overview of how to safely solder onto piezos with silver electrodes and the more difficult nickel electrodes. I'll take you through the process for both silver and nickel step-by-step, and if you'd like to follow along visually, you can watch my video where I demonstrate how to solder a good joint onto both silver electrodes and nickel electrodes.
How to Solder onto Piezo Transducers Video Tutorial
This post is based on a series we do called Tip Tuesday where we explore piezo applications and tips to help you better use and understand piezoelectric materials. Check out our video tutorials page for more. And if you have an idea for a tip, please don't hesitate to leave a comment or contact us directly.
video of soldering onto piezo transducers
What Materials You Need to Solder onto Piezo Transducers
The first thing you need to do to make a good solder joint to a piezo transducer is pick a piezo. I'm choosing between two: one is the easy kind that has a silver electrode. The other is the more difficult kind that that has a nickel electrode and is typical of the type sold by The nickel electrode is only 1000 angstroms thick (an angstrom being 10 to the minus 10 meters) and this has given some people trouble.
The next thing you'll need is some paraphernalia that's very useful for making good joints. Aside from the piezo, the next most important thing is to have some flux. Flux is available in many different places. If you're going to do a lot of this, we have two kits available that have flux, some solder, and a few sample pieces of piezo so you don't have to practice on any good parts you bought.
 - Silver Kit
 - Nickel Kit
piezo kit with solder fluxOur KIT-005 Solder & Flux Kit for Silver Electrode
Other materials you'll need:
 - Small plastic cup - A small plastic thimble cup is needed to put a few drops of flux in. Remember that you only need a small amount.
 - Toothpicks - You only need to apply a very small amount of flux by direct contact. Toothpicks are the perfect size to help you do this.
 - Water - You'll need some water to wash off the flux of the solder joint immediately after you make it.
 - Solder - Of course, you're going to need some solder. You should use small diameter solder (tiny solder, don't use the big fat stuff!). We also recommend that you use the RoHS (stands for Reduction of Hazardous Substances, normally spoken ROHS-HAS) compliance solder that has no lead. There's nothing wrong with any of the joints and it works just as well as the old tin lead solder does. If your prototype ends up working, then it's going to go into production and you're going to have to figure out how to use the stuff anyway so just get it and use it. Better sooner than later, engineers!
 - Flat working surface - It would also be good to have a nice flat working surface, like a small, handy stainless steel plate and a small piece of blue tape for holding things together.
 - Soldering iron - If you watched the video that's at the top of this post, you'll have noticed that I had a very nice digital soldering iron with a kind of probe on it, which is about a 10 watt probe. That's really all you need to make a good joint. Using a big, think solder iron will ruin the joint. It's also unnecessary to have a digital soldering iron, but it helps to know what the temperature is if you're trying to follow directions. In any case, even if you don't have a digital one you will need to be able to control the temperature of the iron somehow or other, so take that into consideration.
 - Wire - Now, you can't just solder any old kind of wire to a piezo. If it's too thick, it will be stiff. When you pick it up afterwards or stress it in any way, the wire has a lot of leverage on that tiny joint you've made and it will break the joint, you'll lose your contact and you'll have to do it all over again.
 The wire I used in the video is about a 32 gauge wire and that's about right for most piezo projects. In special cases, you might need something thicker, but this is a very good option and it's very flexible.
 - Wire stripper - You will also need a tool that can do some stripping. It is possible to do this with a razor blade, but it's a lot more tedious. With the wire stripped, you'll just take off a tiny amount of the insulation. The reason for that is when you have a nice, long piece of bare wire that's multi-stranded, the melted solder wicks back up into the twisted wire where it solidifies and makes a stiff rod and you have a leverage problem all over again.
wire stripper and stripped wire
To give you an idea about what my setup looks like, I've included the image below:
how to solder joints onto a piezo transducer set up
Safety Considerations for Soldering
It is good practice to do your soldering in a ventilated area. In still air, the various volatiles that are created during soldering rise straight up into your breathing zone. The volatiles contain evaporated flux which is slightly acidic, cooked resin components, and even lead and tin if you don't use ROHS "no lead" solder. Some laboratories will have a portable solder fume hood available which will divert the updraft away from the work zone. That's the Cadillac solution.
Another common safety practice is to place a small, low velocity fan (such as those found in computer cabinets) on the bench with a horizontal flow directed across the area where the joint is to be made. That's the Volkswagen solution.
A nice write up by Lawrence Berkeley Laboratory on soldering safety, which is much more general, can be found here.
How to Make a Solder Joint
Silver Electrodes
Now that you've acquired all of your materials, it's time to make a solder joint. I recommend starting the silver electrode as that's the easy one. It's clean, white and is generally easier to solder. In fact, you don't really need any any flux. Usually you can treat this a lot like you would a circuit board.
One technique that works fairly well is taking the soldering iron, getting a little tiny bead about the size of the joint that you want to make on the tip, and you tend the spot where it's going to be. Then you take the wire that you've pre-stripped to a very short amount and you pre-tend the wire. Then you touch the wire to the little blob on the piezo, and that's it. It makes a good joint. It's a lot like a circuit board where you're depending on the flux that's in the solder.
good joint on silver electrodeExample of a good joint on a silver electrode
Nickel Electrodes
If you're working with a nickel electrode, it has to be treated entirely differently. If you were to do the same procedure as a silver electrode, it would simply not stick.
The nickel piezo I use in the video is only 1000 angstroms thick and is very lightweight, so it definitely needs to be held in place with tape so it doesn't slide. Even a slight breath will cause it to move.
To begin, take one of your toothpicks and wet the tip. Then, put a small dot of flux right where you want the joint to be. Now, take your wire and strip a little bit off the tip, taking care not to leave very much wire exposed. Next, dip the wire into the flux. Now you've got the flux dot where you want it to go, you've got flux in the strands of the wire, and you have a soldering iron. Put a bead on the soldering iron that is about the same size as you want the joint. Then, lay the wire right on top of the piezo where you want it to be. Take that solder blob, the wet solder blob, and push it down on the both of them. When you hear a little hissing sound, it's done, don't leave it on any longer than that. Then, take a look at your work and then immediately put it in the water.
Now, if you're in the lab, you don't use a cup of water. You can use a cup if it's on the bench, but if you're near a sink you could put a vessel in it and put your multiple pieces in there and let water dribble into it for about 15 minutes to clean them.
The purpose of the water is to stop the action of the flux. It is a mild organic acid, its water soluble and it's very safe, but it's not safe for electrodes. If you leave it on the electrode, they'll eat it away. So, always, always, wash your joints as soon as possible.

The structure of the blue-black iodine complex of amylose (the linear, helical component of starch), prepared either from iodine and iodide in aqueous solution or from crystalline amylose and iodine vapor, has been studied by resonance Raman and iodine-129 Mossbauer spectroscopy. In both cases it is concluded that the identity of the major chromophore is essentially the same: the pentaiodide (I5-) anion. For the material prepared from iodine vapor, the iodide required for I5- formation is produced by hydrolysis or alcoholysis of iodine. The other product of this reaction, a hypoiodite, has been assigned in the iodine Mossbauer spectrum.

History of aviation in Bangladesh
The history of aviation in pre-1947 India began with kites, the traditional heavier-than-air man-made object that is flown by one or more people while stayin' on the ground, you know yourself like. The first recorded manned flight was arranged by the feckin' Dhaka Nawab Family in 1882, which resulted in the bleedin' death of the feckin' flyer.
Kite flyin' was one of the many different forms of entertainment of the feckin' elite people of Dhaka, since the Mughal period. Whisht now and eist liom. It became a festive tradition durin' the oul' period of Nayeb-e-Nazim Nawajesh Mohammad Khan in the feckin' 1740s. Kite flyin' is still a feckin' popular pastime in Bangladesh, especially right after the bleedin' monsoon. In the oul' older parts of Dhaka it is one of the oul' most popular activities. Kite paintin' was a specialised art form in the feckin' 18th century in Bangladesh. Some kites of Bengal has been known to keep flyin' for three months. I hope yiz are all ears now. They were big kites tied to anchors with stout ropes.
Kite flyin' festival had long been a major festival. Whisht now and listen to this wan. The Chaitra Sankranti festival (known as Shakrain or Hakrain in Old Dhaka) is celebrated every year in the last day of the oul' Bengali calendar (30th Choitro, mid April). It is a bleedin' major event for competitive kite flyin' and boat racin'. Combatin' fighter kite flyers tryin' to shlash each other's carefully sharpened kite-strin' is an oul' major part of the feckin' competition. In West Bengal the oul' major kite flyin' festival happens on the oul' day of Makar Sankranti or end of winter (mid January), and Vasant Panchami (late February).
First manned flight
Jeanette "Jenny" Rummary (performin' as "Jeanette Van Tassell" along with Park Van Tassel), was a young balloonist from the bleedin' United Kingdom, was hired as a part of the feckin' Van Tassell Troupe by the oul' then incumbent Nawab Khwaja Ahsanullah to make a balloon ascension and parachute descent. G'wan now. She had made several previous parachute descents across India since October 1891. Bejaysus. At 6.20 pm on 16 March 1892, she launched from the feckin' bank of the feckin' Buriganga River opposite from the oul' Ahsan Manzil. G'wan now. Ascendin' in the bleedin' balloon, she jumped via parachute as planned to make her descent but was caught in a Casusrina tree in Ramna Park, fair play. Durin' her rescue, she unfortunately fell to the oul' ground and died two days later from her injuries. She was interred in the Christian Cemetery at Narinda, Dhaka.
World War II
Modern aviation in modern Bangladesh area began when the bleedin' British Government of India built a Royal Indian military airstrip in Tejgaon durin' World War II to fly warplanes towards the battle fields of Kohima and war theatres in Burma. Other airstrips were built in Comilla, Feni, Chittagong, Cox's Bazar, Chakaria, Sylhet, Jessore, Rajshahi and Lalmonirhat.
In August 1943, a bleedin' South Asia Command was formed under Admiral Mountbatten, includin' the feckin' RAF Third Tactical Air Force (Third TAF), which launched the oul' second Burma Campaign against the bleedin' Empire of Japan in the oul' December that year. Here's another quare one. The Royal Indian Airforce (RIAF), Indian part of the bleedin' Royal Air Force played a holy crucial role by providin' tactical reconnaissance and extensive close support to the oul' army when a British Corps started advancin' down the Arakan coast in January 1944.
In November 1943, 6 Squadron and later 8 Squadron were moved to Cox's Bazaar. By the feckin' end of February 1944, No 6 Squadron pilots had completed over 1,000 operational sorties, averagin' 6 sorties an oul' day per pilot, a bleedin' record for the oul' entire the Third TAF. Arra' would ye listen to this shite? Towards the oul' end of March 1944, 4 Squadron joined the operations when it was moved first to Feni airfield, and then to Comilla in June to replace 6 Squadron. In March 1944, the bleedin' squadron moved to Feni for operations against the oul' Japanese, to be sure. The role of the squadron was to provide close Air support to the bleedin' XIV Army. it was from Feni that the bleedin' squadron carried out its first operational sorties by providin' fighter escort to Dakota, engaged in supply droppin' missions in the northern Burma. From August 1944 to January 1945, No. Chrisht Almighty. 4 Squadron was based at Cox's Bazar and carried out CAS, interdiction and tactical recce operations.
In May 1944, 9 Squadron was moved to Comilla after a brief spell of tactical reconnaissance duties supportin' the feckin' battles of Imphal and Kohima. Durin' August 1944, the feckin' two squadrons carried out intensive bombin' of Japanese positions in the Sangu River valley, specially for three consecutive days in Labawa to support an offensive by 81 Division to expel the Japanese from the bleedin' area. Whisht now and eist liom. By the end of December 1944, 10 Squadron had also been moved into the oul' operational area at Ramu. With the feckin' fall of Rangoon on 3 May 1945, the oul' operations in Burma were reduced to moppin' up of small pockets of resistance. Arra' would ye listen to this shite? By the end of June most of the feckin' Royal Air forces squadrons were withdrawn, leavin' only 8 Squadron to assist in the bleedin' moppin' up.
The Shahjalal International Airport originated in 1941, durin' the bleedin' second world war, as the bleedin' British government built a landin' strip at Kurmitola, several kilometres north of Tejgaon, as an extra landin' strip for the oul' Tejgaon Airport. At that time Tejgaon was a holy military airport, to operate warplanes towards the war fields of Kohima (Assam) and Burmese war theatres. Shah Amanat International Airport was a feckin' combat airfield as well as a holy supply point and photographic reconnaissance base by the feckin' United States Army Air Forces Tenth Air Force durin' the feckin' Burma Campaign _PHONE_. Known American units assigned to Chittagong were: 80th Fighter Group, flew P-38 Lightnin' fighters over Burma between March 1944 and February 1945; 8th Reconnaissance Group, between October and December 1944 (various detachments); and 4th Combat Cargo Group, flew C-46 Commando transports between January and June 1945. Osmani International Airport in Sylhet was built durin' British rule as Sylhet Civil Airport, partly to check Japanese aggression from Burma. Jaykers! Biman Bangladesh Airlines earns most of its revenue from this airport.
When the oul' war was over, the oul' colonial government decided to build the bleedin' Tejgaon Airport along with a landin' strip at Kurmitola to meet the needs of a bleedin' Royal Indian Air Force (RIAF) station in Dhaka. In 1946, the bleedin' Mirza Ahmad Ispahani and his partners formed an airline – Orient Airways – which soon started usin' the feckin' airport as a civil airport. Shiftin' its base from Kolkata to Karachi when Pakistan was born, Orient Airways started DC-3 flights from Karachi to Dhaka on 7 June 1954, formin' a holy critical connection between the oul' capitals of geographically separated East and West Pakistan. Bejaysus. On 11 March 1955, Orient Airways merged with the government's proposed airline, becomin' Pakistan International Airlines Corporation, later rechristened as Pakistan International Airlines (PIA).
The Eastern Pakistan Flyin' Club was established in 1948, to be sure. By 1960, British Overseas Airways Corporation and Pan American Airways had started operatin' flights out of Dhaka, PIA had started operatin' Boein' 707 and Vickers VC10 jet services, and new airports had been established out of former Royal Air Force stations at Jessore, Chittagong, Thakurgaon, Ishwardi, and Comilla. Durin' the 1962 Sino-Indian War, services to East Pakistan (now Bangladesh) were provin' to be difficult, therefore PIA placed their Sikorsky S-61 helicopters on these routes until 1966 when conditions improved. In the bleedin' 1971 war, PIA aided the bleedin' Pakistan Army by transportin' soldiers to East Pakistan in the feckin' Indo-Pakistani War of 1971 and lost a holy couple of its aircraft to Indian Air Force fighters.

In formal logic, the following are all equivalent:
 if A then B
 if not B then not A
 not B or not A
 A or not B
There may be others. At any rate, "if not B then not A" is one of the
standard transformations. However, I'm a little bit worried about using the
"if not B, then not A" transform as a general device for understanding "if
A then B" sentences that contain negations. In order to make that work
properly, I agree with Grice that you have to bring in a number of
propositions that are implied but not stated, and that some of these things
may be implied by the context in which the statement is made. The result is
that you need many more propositions, not just A and B, if you want to use
formal means to understand conditionals. If Grice is correct - and he is at
least brilliant, whether or not he's correct, and in spite of his
impenetrable writing style - then bringing in all of these propositions
would give you a framework in which formal logic could be used effectively
to understand such statements.
My formal logic is *extremely* rusty, but let me try to use some examples
to illustrate what I mean:
Statement: If he does not come on time then we will wait for him.
A = he does not come on time
B = we will wait for him
If not B then not A = if we will not wait for him then he will come on time.
I'm skeptical that the propositional value of the original statement and
the transformation are the same in this case. Grice says that the reason
for this is that there must be some reason the person is telling us this,
which implies a number of propositions that are implied, but not stated,
1. There is a likelihood that he will not arrive on time
2. We need a plan for dealing with the contingency that he arrives late
(perhaps we were all planning to go somewhere together, and he wanted us to
give him a ride)
3. His tardiness is beyond our control, or if it is within our control,
there is some reason that we prefer not to negotiate with him in order to
get him to come on time, or perhaps there has been negotiation and it was
agreed that we would wait if he comes late
If we do not take these into account, then our formal analysis of the
statement will not be adequate. (If our formal analysis *is* adequate, then
we took it into account (grin!)) In this particular case, I think the
proper analysis requires an understanding that the statement is really
intended to be limited to a plan for handling the contingency that he is
late, and is not intended to be applied if he arrives on time. The "if not
B then not A" transformation took the statement out of context and
broadened its scope. Within the right scope, incidentally, the
transformation might make sense - e.g. perhaps we are formulating a policy
of leaving on time even if some people are not yet there, and we expect
that the result of this policy will be that people arrive on time.
You say that the "if not B then not A" is a good general tool for
understanding conditionals with negatives in both the protasis and the
apodosis. Consider this statement, which is similar to the first, but has
negatives in both the protasis and the apodosis:
Statement: If he does not come on time then we will not leave before he
A: he does not come on time
B: we will not leave before he arrives
if not B then not A = if we leave before he arrives he will come on time
Again, the result of the transformation is a little surprising, and seems
to have a different propositional value than the original statement.
I think that Grice is pretty important for understanding conditionals in
human language. He's also very hard going. I'm not sure who else is
important to read (perhaps Wittgenstein? but I'm not sure which works), but
perhaps some of the linguists on the list will know. At any rate, I think
that there's a fair amount of literature on the treatment of human language
conditionals, written largely by philosophers and linguists, and I know
that I haven't read much of it except for Grice and a little Wittgenstein.

This is too brief for me to agree or disagree with. I'll give you my
off-the-cuff responses to each of these verses, and perhaps you can tell me
how *you* analyze them.
EI MH occurs twice in Matt 11:27 - nobody knows the son EI MH the father,
and nobody knows the father EI MH the son, and those to whom the son
chooses to reveal him. At least some translations (the first few I looked
at) translate this with "except" or "but". Why do you think this changes
the meaning?
In Matt 13:57, Jesus says that a prophet is not without honor EI MH in a
home game. Now I assume your point is that this statement, taken as literal
truth, is false if a prophet is also dishonored outside of his home town.
Your solution is probably to interpret EI MH as something other than
"except". My solution (off the top of my head) is to bring in the larger
context in which the statement was made, and probably to treat this as a
hyperbolic statement - and I do think that Jesus uses hyperbole on other
occasions as well. Of course, hyperbole and other figures of speech are
pretty rough on formal logical analysis, but I'm sure that someone
somewhere has written on this in a useful way.
In John 3:13, the statement is that nobody has ascended into heaven EI MH
him who descended from heaven, the Son of Man. I assume your point is that
there are a couple of people in the Old Testament who ascended into heaven.
In this case, I think you need to look at the scope of the statement -
Jesus is saying that there is only one person who can tell Nicodemus about
heavenly things, the one person who has been to heaven and has descended
from heaven. Now if you want to be strictly literal, yes, there are a
couple of prophets sitting in heaven who have ascended into heaven, but
they aren't on earth anymore, and are not available to explain things to
Nicodemus. If you want to be that literal, Jesus has not yet ascended into
heaven at that point either. (I think there are a lot of uses of "everyone"
and "nobody" in the NT that only make sense with the right scoping.)

Background: Recreational drug toxicity is a common reason for presentation to the Emergency Department. Knowledge of recreational drug names is important to allow targeted assessment of patients presenting with recreational drug toxicity. Aims: To assess final year medical student knowledge of proper and street names for recreational drugs. Design: Questionnaire survey of final year medical students attending a revision lecture. Methods: There were two questionnaires used in this study. The first contained either proper names of recreational drugs or names sounding similar to recreational drugs or licensed pharmaceutical products; students were asked to identify which of these were recreational drugs. The second contained street names of recreational drugs and the students were asked to identify which recreational drug the street name referred to. Results: One hundred and thirty-five students completed the questionnaire 1. The mean total score (±SD) of correct answers was 7.15±2.26 (range 2–13) out of a maximum of 15. One hundred and fifteen students completed questionnaire 2. The mean total score (±SD) of correctly identified street names was 11.0±2.6 (range 0–17) out of a maximum of 24. No individual student was able to correctly identify all the street names for the recreational drugs listed in the survey. Conclusions: We have shown that final year medical students have variable knowledge of both the proper and street names of recreational drugs. There is a need for improved education of medical students in the names of recreational drugs and the sources of information available to assist them in identifying what drugs an individual has taken.

Charlotte Edalji (née Stoneham)
Her English family was at the heart of British imperialism in India
Charlotte Edalji (née Stoneham) (_PHONE_) was the daughter of the Vicar of Ketley in Shropshire and lived almost the whole of her life in vicarages. She had a fascinating ancestry, claiming that one of her family fought in the Crusades and that another distant relative was related to Katherine Howard, wife of Henry VIII. From the 17th century, members of the Thompson, Swan and Stoneham branches of the family were involved in British exploitation and conquest of India. Some stayed in Bombay itself for a period. She campaigned passionately to have her son declared innocent of the attack on a pony for which he was convicted in 1903. She wrote, among others, to the King and the Queen, and appeared on a platform alongside George Bernard Shaw.


Which breeds of dogs are the most stubborn?
Most dogs are stubborn for the same reasons as humans. Some of them are simply born stubborn and masterful, some are born leaders and have corresponding temper, and some simply do not know how to behave. However with patience and with proper training, even the most stubborn dog can become indispensable friend and protector.
Which breeds of dogs are the most stubborn?
Stubborn rocks
Some breeds are harder to train than others. Some of these breeds can grow aggressive if not trained properly. Among the small breeds are dachshunds, chihuahua, pug and dwarf pincher – considered one of the most stubborn. All kinds Terriers, from Parson to Bull Terriers, have a well-known stubborn character. Among larger breeds, relatively rebellious working and protective breeds such as boarders Collie, Rottweiler, Doberman, Newfoundland and Golden Retriever.
Perhaps this is not stubbornness
Your dog may not be stubborn, sometimes she may just feel that she has no good reason to do what you mean ask for. Ask yourself what is the benefit for the dog to commit any action, and give her something that she can appreciate. For example, all terriers were bred for hunting, not for entertainment. So if you want to play with him just give him a reason to return the ball to you.
Some dogs were bred to perform certain tasks. without human intervention and therefore need little praise from the owner. For example, hunting or herding dogs could not to do their job if they expected attention from people. In this the group, in addition to terriers, also gets the majority of huskies and spaniels. Always consider for what purpose your breed.
There are other reasons.
Some dogs, such as shepherds, are especially sensitive to the emotions of his master. Your mood can greatly affect your pet's behavior and make learning difficult. More he upsets you, the more he upsets himself. Besides, often dominant behavior in some dogs can be caused external factors, such as annoying behavior of others. Or a dog as it grows older can just sometimes marry framework "as children do.

Let's consider curve $C\subset \mathbb P^n$ of degree $d$ and genus $g$. We want to calculate dimension of deformation space of $C$, i.e. $h^0(C,L)$ where $L$ is the normal bundle.
We can decompose $L$ as $L_1\subset L_2\dots \subset L$, such as $dim L_{i+1}/L_i =1 \ $ and apply Riemann-Roch to each $L_{i+1}/L_i$.
I heard that this gives us $(n-1)(d-g+1)+2g-2 + 2d\ $ (as expected to be dimension of deformation space of $C$ or the number of points need to fix to count curves degree $d$ and genus $g$ passing through them).
But I can't calculate it! Could you help me with this or give me a reference?

Let's start by stating Riemmann-Roch for vector bundles: If $C$ is a smooth projective curve of genus $g$, and $E$ is a vector bundle of rank $r$ and degree $\delta$, then $h^0(C,E) - h^1(C,E) = \delta - r(g-1)$. If $E$ has a filtration such as you describe, you can prove this by using Riemann-Roch on each quotient line bundle, and then adding up the contributions in the long exact sequence of cohomology.
Now, we want to consider the case where $E$ is the normal bundle $N$ to $C \subset \mathbb{P}^n$. The rank of $E$ is $n-1$. We have the short exact sequence $0 \to T_C \to T_{\mathbb{P}^n}|_C \to N \to 0$. The tangent bundle to $C$ has degree $-(2g-2)$. The tangent bundle to $\mathbb{P}^n$ has first chern class $(n+1)$ times the hyperplane class; the hyperclane class restricts to $d$ times the fundamental class of $C$. So the degree of $N$ is $d(n+1) + (2g-2)$ and Riemann-Roch gives $$d(n+1)+(2g-2)-(n-1)(g-1)$$ which matches your formula.

In English, before clocks were commonplace, the word "clockwise" was obviously not in common use. Instead, the closest alternative to "clockwise" was the now-archaic word "deasil", and its antonym was "widdershins" (or, perhaps, people just used "right" and "left"; see also: What did we say before "clockwise"? on English.SE).
The Japanese word for "clockwise" - 時計回り - also involves clocks. What was the Japanese word for 時計回り before 時計 became commonplace? I see that 右回り is given as a synonym/definition for 時計回り in some dictionaries; is this what was most commonly used in olden times?
The content below is an exact copy of a deleted answer by user l'electeur.
Noun: [右]{みぎ}ま
Verb: 右へま
は ＞ わ back then.
Even today, 「右まり」（は changed to わ over time） is a far more intuitive word than 「[時計回]{とけいまわ}り」 for native speakers. The only time I myself used 「時計回り」 and 「[反]{はん}時計回り = "CCW"」 often in my life was when I was working for a machine manufacturer. Even then, I was using 「右まわり」 and 「[左]{ひだり}まわり」 outside of work.
According to this source _URL_ the term 時計回り was also used with sundials, and though the length and time of sunlight varied with seasons, the direction didn't, so 「時計回り」was always in use.
This link _URL_ presents the other versions 「右回りと左回り」.Clockwise is 右回り.
 - OP is asking about the word for 時計回り before any kind of 時計 was introduced to Japan. – a user Jan 18 '15 at 3:07
 - _USER_ Well, to be fair, I hadn't considered sundials, which I imagine would have been in Japan since before historic times. If sundials were called something like 時計 even before the introduction of mechanical clocks, then it would make sense that 時計回り would have been used for a long time. It looks like sundials are called 日時計 today, but I don't know whether they were called that in the past or if the name is sort of a "back-formation" from 時計 as in "mechanical clock". – senshin Jan 18 '15 at 8:15

What is the Probability of Profit (POP)?
It is the chance of making at least $0.01 on a trade
The Probability of Profit, or more commonly referred to as POP, is the theoretical probability of your equity/etf position(s) making at least $0.01 on a trade. POP uses a set of variables such as position type, whether you are long or short, time, and volatility (for the distribution curve).
What is the Equity Probability of Profit (ePoP)?
It is the chance that your portfolio's equity/ETF positions make at least $0.01.
The Equity Probability of Profit (ePoP) is the theoretical probability of profit of your portfolio's equity/ETF positions (stock & options) making at least $0.01. ePoP does not apply to futures or futures options positions.
Where can I view POP or ePoP?
Profit Probability displays two different ways–a per position level or portfolio level
POP displays during order entry in the trade details area. Additionally, after you open the position, you may view PoP in the Positions tab by adding the POP column.
You can view your Equity PoP, or ePoP, by adding the column to your Account Header Details on the desktop platform. Additionally, ePoP displays to the left of the Account drop-down menu at the top of the web-browser platform.
How do you calculate POP & ePoP?
The POP algorithm has two different modes behind the calculation
Currently, PoP graph view is only available on the web-browser platform. We plan on extending this feature to the desktop platform with future updates. That said, both calculation methods use the portfolio's beta-weighted symbol. By default, the platform beta-weights to SPY. To learn how to change your portfolio's beta-weighted symbol, please click here.
Single Underlying (POP)
When viewing the POP of a single underlying, POP bases it on a simple P/L graph of the underlying. The example below illustrates a single iron condor. Furthermore, a distribution curve based on the portfolio's beta weight is applied (default is SPY). That means if you have a position with a 7-days-to-expiration (DTE) option and a 21 DTE option, then the POP calculation will use the 21 DTE distribution curve (or the volatility index) of the portfolio's beta-weighted symbol. As a result, the total area under the distribution curve when profit goes to 0 equals 1 (shaded yellow) The beta-weighted area in the distribution curve where the position generates a profit (shaded green) is subtracted from 1, thus producing the POP.
Multiple Underlyings (ePoP)
When viewing portfolio ePoP of a portfolio, a single P/L graph of the portfolio generates based on the portfolio's beta-weighted symbol (default is SPY). Similar to the way a single underlying P/L graph generates, the total area under the distribution curve (or volatility index) when profit goes to 0 equals 1 (shaded yellow). The beta-weighted area in the distribution curve where the portfolio generates a profit (shaded green) is subtracted from 1, thus producing the ePoP.

Sector-specific Case Studies and Examples
As part of our materials to strengthen Managing for Development Results (MfDR), we have developed Case Studies and worked examples of a Stakeholder Analysis, Problem Tree, Objectives/Vision Tree, Risk Analysis, and good practice Log Frame for five different sectors: Forestry, Agriculture/Trade, Climate Change; Micro, Small and Medium Enterprises, and Education. These can be used in training or advisory services – or new ones can be developed for bespoke capacity strengthening assignments.
Quality Assurance (QA) checklists
CIDT has developed a modality of QA checklists that have proven helpful in guiding the review and assessment of the various elements of results frameworks. We use them to gauge the strengths and weaknesses of 'real' results frameworks, in order identify their strengths and possible areas for improvement. As a trainer or expert providing technical assistance, these checklists provide an objective way to assess a product from a technical perspective and to communicate the findings and suggestions. We have also assisted our clients (of advisory services) or participants (of workshops/trainings) to use these checklists. They have been a great asset to Peer Review exercises, enabling individuals to provide constructive feedback.
We also have a checklist for the review the quality of Monitoring and Evaluation (M&E) plans, which can be used to assess and score the M&E component of project proposals, to facilitate peer review during M&E workshops/trainings, or to conduct a self-assessment of a 'real' M&E plan.

The Gold Mystery Snail is one of about 120 species belonging to the Ampullariidae family. The Ampullariidae family name is also sometimes referred to as Pilidae.The most visible characteristic of snails belonging to the Pomacea genus is the siphon. When needed, this siphon will extend out to the water surface allowing the snail to breathe while submerged.
Question - How long do mystery snails hold their breath? 51510 - in Snails forum - This may sound dumb, but I'm wondering how long my mystery snail can hold its breath. My husband and I are the quintesential overbearing...
The Black Mystery Snail will tolerate quite a broad pH range and will do well as long as the pH is kept between 6.5 and 8.0. The KH should be in the 12-18 range and the water temperature from 68 to 85° F. As mentioned above, the Black Mystery Snail needs to breath oxygen from the air and will drown if prevented from this. You should therefore ...
They can breathe air like land creatures. In some cases, mystery snails may escape their tank and stay outside. They will have no problem being out of the water. 5. How often do mystery snails lay eggs? Mystery snails can lay eggs, on average, every few weeks. AFter that, there is usually a 2 to 3 week period for the snail starts to lay eggs ...
Blue Mystery Snails' shells are a gorgeous and calming light blue color. ... They will climb up to the water line in to breathe air, so it's a good idea to make sure the water line in your aquarium isn't too high. When a Mystery Snail reaches the top of a wall or structure, it will often let go of the wall and glide rapidly downward until it ...
They extend this tube up above the water line and then move back and forth to take the air in. If you search on the Internet for mystery snails, many results will state that these are the same species as Apple snails. Our Mystery snails are NOT Apple snails, though they do resemble them in shape and general appearance.
If you're about to put a snail into a fish bowl, ensure that there's a lid on the bowl! Otherwise you'll find your snail(s) how it crawls and explores the room. Plenty of things can be used as covers. Bear in mind that water changes are necessary! Mystery snails can breathe atmospheric air, but you should use an air pump too.
Those lung-breathing snails make, by far, the largest part of known gastropod species. The advantage of breathing with lungs is obvious: Those snails can breathe oxygen from dry air and do not have to rely on water. To be able to do this, fresh water snails breathing with lungs have to regularly go to the surface.
Yes they do breathe air from water they is how they stay alive they can live for a month under water you also may see a pond snail upside down with their bottoms out of the water they are breathing!

To create a collapsible set in jQuery Mobile, follow these steps:
 1. Start by creating a basic HTML structure for the collapsible set. It should include a main container with one or more collapsible sections inside it. Each section should have a header and content.
 1
 2
 3
 4
 5
 6
 7
 8
 9
10

Section 1

Content of section 1 goes here

Section 2

Content of section 2 goes here

 1. Add the jQuery Mobile library to your project. You can do this by downloading it from the jQuery Mobile website or by using a CDN.
 2. Initialize the collapsible set using the .collapsible() method provided by jQuery Mobile. This will add the necessary styles and behavior to your HTML.
1
2
3
$(document).ready(function(){
 $('[data-role="collapsible-set"]').collapsible();
});
 1. Optionally, you can add additional configuration options to the .collapsible() method to customize the behavior of your collapsible set. For example, you can set the default state of each section to open or closed using the collapsed option.
1
2
3
4
5
$(document).ready(function(){
 $('[data-role="collapsible-set"]').collapsible({
 collapsed: true // all sections start closed
 });
});
That's it! Your collapsible set should now be fully functional. When a user clicks on a section header, the content of that section will expand and collapse.
