In the previous post, I mentioned the 6 services essential to wrap up the Tribal Wars 2 manager: data collection, alert, farm, ops and build-recruit services. Before that to happen however, we need to figure out a way to talk to the game i.e. the authentication service.
Core service overview #
Core services
The source code for this service is hosted at _URL_
The authentication service is sandwiched between the 6 services and the game server. Its purpose is to manage authentication and the message flows to and from the game. At its core, the service has 6 components: socket client, authenticator, log builder and 3 MQ (message queue) components. Each of these components are developed as singletons to:
 - Limit the number of queues and exchanges created on RabbitMQ for MQ components.
 - Limit access points to disk (logs) and game server in case an object is called twice during initialization.
The following sections describes each component in more detail with links to the source code. Please note that the source can change in the future and you should always have a look for the code in the master branch.
Socket Client #
SocketClient (src) is a singleton class, responsible for managing a connection to the game server and handles messages in-and-out of the game to the Authenticator component. To use this class, request for an instance by calling SocketClient.shared.
This class has 2 message handling features: fire-and-forget messaging to the game with fire(message: ISocketMessage), and asynchronous request/reply messaging with request(message: ISocketMessage, reply: (replyMsg: ISocketMessage) => void) and reply(message: ISocketMessage).
To ensure that messages are matched to the request, the game employs an id field. For example, when a request is sent with
{
 "type": "Authentication/login",
 "id": 2,
 //... other data
}
The game would respond with either of the following:
// Valid credentials
{
 "type": "Login/success",
 "id": 2,
 //... other data
}
// Invalid credentials
{
 "type": "System/error" // or something else, I can't remember
 "id": 2,
 //... other data
}
Either way, there's a match of id of 2 in the response field. Internally, SocketClient uses a private _msgId field and an array _replyQueue to keep track of requested IDs to match for responses when they come in.
SocketClient extends node's EventEmitter class. A list of events can be found in SocketClientEvent enum.
Authenticator #
Authenticator is a singleton class, responsible for managing the client sessions and connections to both the game via SocketClient and RabbitMQ via the 3 MQ components. To use this class, request for an instance with Authenticator.shared.
Tribal Wars 2 login message requires a username field of name in the message but does not specify how the password is passed in. This is done either with a pass field with raw password text or token, a generated hash which I have no idea how they get it. In this application, I opted with using pass.
The authenticator starts and ensures the player is authenticated with the game using SocketClient before starting MQ components to ensure that the queued messages will not be processed before the game is connected.
The sequence of data to be sent and received for authenticating a player is shown in the Kibana logs for game-messages.log in the Results section.
MQ components #
The auth-svc has 3 MQ classes as singleton-classes. Each of these are responsible for a different category of messaging to-and-from the game.
Messages sent to and from the game can be divided into 3 categories: request for information (villages on the map, player data), notification from the game (incomings, building/recruit task is completed) and changing a configuration (enable notifications). Due to this nature, the authentication service includes 3 MQ components as mentioned. This is similar to how the game's socket service works behind the scene.
MQProducer and MQConsumer are topic exchanges. When receiving a message through MQProducer.send(message: ISocketMessage) (not a static method), the topic key is created by replacing / with . and send to from.game.exchange to be distributed to interested services. The socket message is sent as a whole. MQConsumer is a queue listening to the to.game.exchange. It listens to everything # and forwards the messages to Authenticator for processing. Currently, the Authenticator class does not attempt to verify the messages.
MQRpcServer implements the RPC pattern. It listens to game.rpc_server queue and sends messages to Authenticator by emitting an event. Aside from the game message, MQRpcServer also passes along the MQ message to be stored in Authenticator to async callback can be achieved.
Log Builder #
The service includes 2 log files stored at /var/log/ in a Node container: game-messages.log and services/auth-svc.log. These are created and written to by the LogBuilder built with WinstonJS. Type and direction of data flows are separated by colours in the diagram above.
FileBeat is configured to monitor /var/log/game-messages.log and /var/log/services/*.log for log files. New log files from other services will be placed in /var/log/services/. This is accomplished by sharing a volume between multiple services.
Secrets #
Throughout the development cycle, I have been using environment variables to load in the player's username, password and world ID. For deployment, these will be replaced with Docker secrets in Docker Swarm.
Changes to technology choices #
From developing this service, I am going to change the deployment technology to Docker Swarm and proxy tool to Traefik.
Kubernetes has a lot of baggage. You don't just use Kubernetes, you use all the tools that makes it better like Helm and Istio. There's a whole new set of commands and languages you gotta master. Docker Swarm's learning curve is less steep. Once you knew Docker CLI, getting the hang of Swarm is easier. Orchestration is a big topic, but the tools shouldn't make it harder.
Next up is Traefik. After using it to configure this blog thanks to Ghost, I don't think that it's the right fit for microservices. For new services and end-points, NGINX needs you to edit and confgure a conf file. These files need to be curated and version-controlled. Traefik's way of configuration by enabling a flag in the docker-compose file is a god-send. The Traefik guys have got to do more marketing to compete.
Putting in the Elastic Stack #
This section is more of a rant. If you want to have a look at the code that makes up the stack for this project, head over to _URL_
In this project, I wanted to setup Elasticsearch, Kibana and Beats on Docker containers. Elastic Co has a reference Elastic stack Docker repository.
The repository sets the default password, create keystores to store passwords and install dashboards, index patterns for beats and apm. That's great and all but the free Elastic stack doesn't have authentication built-in. No security ticks in the Free tier. The LICENSE (Apache 2.0) is no help either. Is this a trial? Yes it is. That was a lot of clicks to find out what's the T&Cs huh.
I don't want my centralised logging service to stop working after 30 days, plus I have mixed feelings about the security feature for this project. Every services are going to be run on the player's machine. Adding security and secrets increase the complexity for development, so at worst when the players want to have some authentication, they could have the services sit behind a proxy like NGINX or Apache and put in authentication. The repository was definitely helpful however, I find their setup-beat.sh helpful in configuring and setting up Elasticsearch and Filebeat.
Spinning up Elasticsearch, Kibana and Filebeat on their own containers was simple enough. For this first step, I chose not to use Logstash and instead use Elasticsearch's ingest nodes to talk to Filebeat. I ran into a wall when trying to configure Elasticsearch's pipelines however.
Firstly, Compose's depends_on and links controls the start-up order of services, not checking and polling the dependencies' health before starting the service of interest. In my case, I wanted to run a shell script to POST custom pipelines into Elasticsearch once it's healthy. In my case, I went with creating a separate container with a script that keeps waiting until Elasticsearch is ready, similar to how setup-beat.sh works.
Secondly, Elastic's documentation is not noob-friendly. Run the Filebeat setup section in Filebeat on Docker documentation includes the setup command which is not explained. Further down the page where the volume-mounted configuration code

Chicken feathers, as unlikely as it seems, have turned out to be a wonderfully useful material. Among other things, researchers have found they make for great circuit boards and cheap, efficient storage tanks for hydrogen. Now it turns out they could also be used to create biodegradable, petroleum-free plastics.
Researchers at the University of Nebraska-Lincoln say that the protein keratin in chicken feathers, which is strong and durable, as well as the fact that so many of them end up as unused waste, is what makes them such an appealing material. When making the plastic, the scientists heat-treated the feathers to clean them and then pulverized them into a fine powder. They then added chemicals that made the keratin molecules join together into long chains and create a polymer.
The resulting plastic was stronger than other bioplastics made of soy beans or starch and it stood up to water. The material is a thermoplastic which means that heat can be used to mold it into various products and can be melted and remolded many times. It could be used for plastic plates and cups or even furniture and when those things are no longer usable, the plastic is biodegradable.

AMMAN – Conservationists on Sunday called on the public to report to the authorities any individuals emptying materials into the Gulf of Aqaba, following the discovery of dead fish in the Red Sea.
On September 5, Royal Marine Conservation Society of Jordan (JREDS) teams recorded several dead fish floating in the Gulf of Aqaba, JREDS Executive Director Fadi Sharaiha said yesterday, noting that samples were sent to labs to identify the cause of death.
"Lab tests indicated that the fish were poisoned by a chemical substance," Sharaiha told The Jordan Times over the phone yesterday.
He noted that the society informed the Aqaba Special Economic Zone Authority (ASEZA) for further investigation as a precautionary measure, noting that the incident was the second registered case since the beginning of the year.
Sharaiha speculated that the poisoning was either due to a person illegally dumping chemical substances into the sea or a fisherman's botched attempt to sedate the fish.
"We urge people to contact authorities about any individual dumping substances into the seaة preserving marine life is a joint responsibility," Sharaiha highlighted.
Meanwhile, ASEZA Environment Commissioner Salim Moghrabi confirmed the incident, but stressed that the number of dead fish was "very limited" and refuted speculation that fishermen sedated the fish.
"Fishermen in the Gulf of Aqaba are law-abiding and they use legal and traditional ways to catch fish. ASEZA carries out strict and systematic monitoring of the beaches as well as meat and fish sold at markets," Moghrabi told The Jordan Times over the phone yesterday.
He noted that authorities have not received any health-related complaints regarding fish unfit for human consumption.
The environment commissioner said he suspected that the death of the "limited number of fish" was caused by people who illegally use chemical substances to sedate tropical fish living in the coral reefs to catch and sell them as pets on the black market.
Reputed for having one of the world's most unique coral reef systems, Aqaba's Red Sea waters are a prime attraction for both tourists and divers.
Some of the underwater treasures include around 127 species of hard coral and 300 kinds of soft coral, and thousands of plants and animals that have coexisted in the gulf for hundreds of years.

For zeotropic mixtures, the temperature varies during phase change, which is opposed to the isothermal phase change of pure fluids. The use of such mixtures as working fluids in organic Rankine cycle power plants enables a minimization of the mean temperature difference of the heat exchangers, which is beneficial for cycle performance. On the other hand, larger heat transfer surface areas are typically required for evaporation and condensation when zeotropic mixtures are used as working fluids. In order to assess the feasibility of using zeotropic mixtures, it is, therefore, important to consider the additional costs of the heat exchangers. In this study, we aim at evaluating the economic feasibility of zeotropic mixtures compared to pure fluids. We carry out a multi-objective optimization of the net power output and the component costs for organic Rankine cycle power plants using low-temperature heat at 90 ◦C to produce electrical power at around 500 kW. The primary outcomes of the study are Pareto fronts, illustrating the power/cost relations for R32, R134a and R32/R134a (0.65/0.35mole). The results indicate that R32/R134a is the best of these fluids, with 3.4 % higher net power than R32 at the same total cost of 1200 k$.

I'm new to Hadoop and was curious about the commandline messages from my pig script.
Total records written : 7676
Total bytes written : 341396
Spillable Memory Manager spill count : 103
Total bags proactively spilled: 39
Total records proactively spilled: 32389322
The end result is indicated to be a "Success!". I am still not sure. What do these numbers above mean?

The first two shows the total records/bytes written to HDFS by your MR job.
It can happen, that during a MR job not all records fit into the memory. Spill counters indicate how many records have been written to the local disks of your datanodes to avoid running out of memory.
Pig uses two methods to control the memory usage and do a spill if necessary:
1. Spillable Memory Manager:
This is like a central place where the spillable bags are registered. In case of low memory this manager goes through the list of the registered bags and performs a GC.
2. Proactive (self) spilling:
Bags can also spill themselves if their memory limit is reached (see pig.cachedbag.memusage)
Back to the statistics you have:
 - Total bags proactively spilled: # of bags that have been spilled
 - Total records proactively spilled: # of records in those bags
It's always good to check the spill stats of your job since lot of spilling may indicate huge performance hit that need to be avoided.

Birth of Fatmawati Soekarno
Edwin Solahuddin Kamis, 5 Februari 2009, 00:02 WIB
VIVAnews – 86 years ago today, on 5 February 1923, Fatmawati Soekarno, the third wife of the first president of Indonesia, Soekarno, was born.
Fatmawati was born in Bengkulu into a religious family. Her father, Hassan Din, was one of the most prominent figures of Muhammadiyah in the province.
In March 1938, Soekarno, who was already famous as the leader of the nationalist movement at the time, was exiled by the Dutch to Bengkulu. The house where Soekarno was held was not far away from Fatmawati's house. Since the Dutch government allowed him to interact with the local people, Soekarno soon became acquainted with the local leaders, including Hassan Din, Fatmawati's father.
Soekarno married Fatmawati on 1 June 1943. The couple had five children including Megawati, their first daughter, who later became the fifth president of Indonesia.
Fatmawati is famous in Indonesian history as the person who knit the Indonesian flag used during the proclamation of independence in 1945. She was known to her family and friends as a kind, cheerful and modest person. She was not ashamed of washing her family's clothes in Kali Code (a river in Yogyakarta) when she and her family took refuge in Yogyakarta in 1949.
Fatmawati Soekarno died on 14 May 1980 in Kuala Lumpur and was buried at Karet Bivak Cemetary in Jakarta. To commemorate her struggle, a hospital in South Jakarta was named after her. Later, a street and an airport in Bengkulu were also named after her. In 2000, the Indonesian government made Fatmawati a national hero.

Why you Should not Suppress your Emotions
A submissive woman who does not respond assertively to her abusive partner, a man who drinks in order to escape bad moods for a moment, a person who tries to keep himself busy in order to forget his problems, are examples of people who suppress their emotions.
Many people suppress their emotions thinking that by doing so they have managed to get rid of problems but this practice usually lead to a bigger problem. Suppressed emotions usually manifests in one way or another. For example a man who has an abusive boss can turn out to be abusive towards his children. In this case this man directs his suppressed anger toward his children because he can't direct it towards his boss.
In my article "how to stop a narcissist from ruining your self-esteem" I said that, not responding assertively to an abusive narcissist is one of the things that can ruin your self-esteem.
Suppressed Emotions can bring bad Moods
One of the causes of bad moods and depression is repressed emotions. Your brain usually gives you negative emotions so that you solve a particular problem or achieve a certain goal. When your mind realises you are in the right direction towards solving that problem, it will send you positive emotions. On the other hand when your inner mind thinks that you are stuck and doing nothing to solve your problems, it will send you bad moods, sadness and depression.
Now, when you suppress the bad emotions that your inner mind is sending you so that you deal with a particular problem, it will realise that you are defying it, therefore, it will keep sending you even more intense bad moods.
Suppressed Emotions can Cause bad Dreams
I strongly agree with Alfred Adler's interpretations of dreams. One of his theories states that dreams are nothing but a reflection of what's happening in your life. Your inner mind (subconscious mind) usually uses dreams to remind you of a particular issue or to help you solve a certain problem. For example if at work you were assigned a role that you are not prepared for, you can dream of being at school, where you are being given an exam that you are not prepared for. This is because dreams usually come in symbols.
Bad dreams and nightmares are not different. Your mind can give you nightmares because there is important problem that you are trying to escape instead of dealing with it, maybe because you are afraid to face it.
Yes, the monster that was chasing you in your dreams might be a symbol of your abusive boss or any other issue that you are afraid of facing.
Suppressing Emotions and Attracting Difficult People
If you usually suppress your emotions when you are being mistreated then you can attract narcissists and abusive people.
Narcissists and abusive people usually target a victim that they can abuse without facing serious consequences. Therefore it you are too submissive you can attract them.
How to stop Suppressing your Emotions
You have to deal with the real issue that makes you suppress your emotions. In my previous article "understanding codependency" I said that fear of rejection can make a codependent person suppress his negative emotions. In this case unless he deals with his fear of rejection, build self-esteem and end codependency, he may always find it difficult to not repress his emotions.
Whether you have developed a bad habit of escaping from problems instead of dealing with them, whether it's fear that makes you suppress your emotions or whether you learned that from your childhood, it's very important to understand the root cause of that behaviour first. (See: how to stop being overly sensitive)


CUDNN Batchnorm Backward result is not correct? Found big difference than CPU result.
We observed that the Batch Normal Backward calculation between CPU and CUDNN has big difference.
Can CUDNN expert share some information about the difference between CUDNN and CPU for Batch Normal Backward calculation?
 - The related call to CUDNN is "wrap::cudnnBatchNormalizationBackward()" (tensorflow-1.8.0/tensorflow/stream_executor/cuda/cuda_dnn.cc:Line-3138)
We are using following resources:
 - cuda-9.0.176.3
 - cudnn-9.0-linux-x64-v7 (libcudnn.so.7.0.5)
 - Nvidia TITAN V (V100), with nvidia-driver-x86_64-390.77.run (on Ubuntu-16.04)
 - tensorflow-gpu-1.8.0
Please check below for the detailed background:
When evaluating batch normal BACKWORD float16 calculation with CUDNN(Volta Tensor Core) and CPU:
We firstly dump a data set from a real model run (with CUDNN) then feed into following four standalone tensorflow scripts and got four outputs:
 1. CUDNN-with-input-float16, output-float16
 2. CUDNN-with-input-float32, output-float32-then-convert-to-float16
 3. CPU-with-input-float16, output-float16
 4. CPU-with-input-float32, output-float32-then-convert-to-float16
We expect that the four float16 outputs are very close and no big difference, but the real finding is:
 - the output 1 and 2 has no difference with the real reference data, (which proves the data is correct)
 - there's no difference between output 1 and 2
 - there's no difference between output 3 and 4
 - difference between 3(or 4) and 1(or 2) is unexpectedly big (average relative diff is about 67%)
Our concerns are:
 1. why the difference is such big between 3(or 4) and 1(or 2)?
 2. does the difference has any side effect to the convergence for models using CPU-float32 calculation?
Could any CUDNN expert share any info about the difference between CUDNN and CPU calculation for Batch Normal backward?

There is of course the standard construction of the reals by considering the set of sequences that are Cauchy with respect to the standard metric and taking the quotient by sequences that converge to 0, but in many other cases of the completion of a ring or group, we can complete by taking an inverse limit of factor rings/groups corresponding to some predetermined ideals/subgroups. For example, the $\mathfrak{p}$-adic integers are constructed using precisely this type of inverse limit construction, where the ideals are the powers of $\mathfrak{p}$, where $\mathfrak{p}$ is the ideal $(p)$ for $p$ a prime.
Is there any way to construct the reals using a similar inverse limit construction?
It seems like this might be related to the so-called "infinite prime", but I don't know if there is really a way to complete with respect to an "infinite prime", which doesn't seem like it is strictly a prime integer or ideal, so that doesn't really seem to help..
(If anyone can think of better tags, please go ahead and change the ones I've used. I wasn't really sure how to classify this).

It appears to me that it is not the arithmetic but the ordering that plays the game here. The question seems to still make sense if we ignore the arithmetic structure of rational number and only look at it as a countable dense linear ordering without end points. My first reaction is no, but I don't have a good argument for it. – abcdxyz Mar 30 '10 at 10:04
The infinite prime is certainly a mathematical object in the context of Arakelov geometry, although I don't know if that's relevant here. – Qiaochu Yuan Mar 30 '10 at 10:07
Rather, it's not strictly a prime. – Harry Gindi Mar 30 '10 at 10:10
I think the things are the other way round. Since both usual primes and the Euclidean metrics define absolute values, and you can do many similar constructions with them (e. g. completion) it is sometimes more convenient to think of these objects together. So, given a global field K with a maximal order O, one often consider the set of places of K (equivalence classes of absolute values) as a better behaved replacement of Spec(O). In this sense the absolute value itself is a "generalized prime" tautologically, but this surely does not answer your question. – Andrea Ferretti Mar 30 '10 at 10:15
In the category of archimedean ordered fields, $\mathbb{Q}$ is initial and $\mathbb{R}$ is terminal. I think this mirrors what happens at finite primes pretty well (a little too well, in fact). – François G. Dorais Mar 30 '10 at 11:44

Although your question is not at all vague, there are a few completely different ways to interpret what a good answer would be. Knowing a bit about your personal preferences, I suspect the following is not at all what you wanted, but it is still of interest to the community.
The fact that $\mathbb{Q}_p$, for example, can be seen as an inverse limit boils down to the fact that the series representations $$\sum_{n \in \mathbb{Z}} a_n p^{-n}$$ give a homeomorphism between $\mathbb{Q}_p$ and the subspace of $\{0,1,\dots,p-1\}^{\mathbb{Z}}$ of eventually zero sequences (on the positive side). At first glance, it would seem that the same works for $\mathbb{R}$ since every element of $[0,\infty)$ has a very similar binary expansion $$\sum_{n \in \mathbb{Z}} a_n 2^n$$ where $(a_n)_{n \in \mathbb{Z}}$ is again in the space of all eventually zero sequences in $\{0,1\}^{\mathbb{Z}}$. Unfortunately this is not a bijection. In fact, there is no way to select such a sequence $(a_n)_{n\in\mathbb{Z}}$ continuously — binary rationals are always points of discontinuity no matter how the selection is made.
There is a funny way to remedy this which is commonly used in Computable Analysis and Reverse Mathematics. The idea is to represent real numbers again with series of the form $$\sum_{n \in \mathbb{Z}} a_n 2^n$$ but where $(a_n)_{n \in \mathbb{Z}}$ is now an eventually zero sequence from the extended set $\{-1,0,1\}^{\mathbb{Z}}$. The obvious cost is that no number has a unique representation in this form, but the side benefit is that the binary rationals are no longer'special' in this way. In the end, this representation is extremely well behaved compared to ordinary binary expansions. This can be seen from the fact that any invariant continuous function between representations (see note) gives rise to a continuous function $\mathbb{R}\to\mathbb{R}$, and every continuous function $\mathbb{R}\to\mathbb{R}$ admits such a lifting.
The conclusion to draw from this is that, up to some very nice blurring, $\mathbb{R}$ is indeed an inverse limit just like $\mathbb{Q}_p$.
Note: The topology on eventually zero sequences is not exactly the product topology, it is given by the metric $$d(\vec{x},\vec{y}) = \inf\{2^n : \forall m \geq n\,({x_m = y_m})\}.$$ The invariance of a function $f$ between eventually zero sequences from $\{-1,0,1\}^{\mathbb{Z}}$ means that if $\vec{x}$ and $\vec{y}$ represent the same real number then so do $f(\vec{x})$ and $f(\vec{y})$.

You can express the condition that $a_n$ is eventually zero as follows: $$\sum_{-\infty

Good Old-Fashioned Fish
(yes, Lembeh has some of these)
The comet fish's round marking makes it look like a moray eel if it slots itself into appropriate cracks. Is that cool or what?
This batfish is making a stop at one of the cleaning stations - the blue line you see near the fish's mouth is actually a cleaner wrasse.
Our serious books didn't say why filefish are called filefish, so I went to Wikipedia, which says that the name is because of its sandpapery skin and compressed body. It 'is said' that dried filefish skin was once used to finish wooden boats.
Yellow-Barred Jawfish
Freckled Goatfish
Two very similar tobies - I couldn't decide which one was fingerprint or papuan.
Tobies are small pufferfish. As the name implies, pufferfish can expand their bodies when provoked. And if they're eaten, the poison in their tissue can be toxic.

From telescopes to the Erie Canal, to planes, trains and automobiles, technological innovations have long been incorporated into wallpaper designs. With cast iron reaching new aesthetic and structural heights in architecture beginning in the 1850s, it made sense to capture its more decorative aspect in a wallpaper design. This paper highlights views of New York City architectural landmarks including Trinity Church, Federal Hall, Exchange Place, Grace Church, and Castle Garden, with each view enclosed within a decorative cast iron framework. Flowering vines are entwined around the support columns. A narrow border fragment is still attached at the top edge with the border colors matching those found in the sidewall paper. The format of this design is quite typical for the period but the normal framing elements of scrolling foliage and wood moldings have here been replaced with decorative cast iron. While the maker of this paper is unknown it is appropriate that the cast iron design incorporates New York City landmarks as there were numerous cast iron foundries in New York City. The SoHo (South of Houston) district of New York City contains possibly the largest collection of cast iron architecture in the world.
With origins dating back to ancient China, cast iron was not a new material at this time but there was a boom in its use for architecture. Refinements in its production allowed the material to be used as a structural element in large building projects beginning in the late eighteenth century, while its cheapness and availability in the 1850s led to its increased use in architecture. Support columns made of cast iron were more slender than those of masonry supporting a similar weight, which created more usable interior space, and also allowed for larger, more decorative windows when used on the exterior.

How to Sedate a Dog for Grooming?: Keep a Dog Calm while Grooming
How to Sedate a Dog for Grooming
Grooming dogs is a task when you do it at home. Many dogs become anxious and do not stay still while you are grooming them. As the dogs don't stay calm, it also becomes a bit of a task for the owner to groom their little pet. There are several ways to make sure that your dog stays calm during the entire grooming session. The process of giving sedatives that calm your dog down is called Sedation.
Sedatives : Drugs available in the market for sedating your dog
When the dogs are sedated, it calms them down. A dog is in a tranquil state due to sedatives, and this can help during grooming session or whenever you are visiting the vet. Many dogs become restless and start moving during stressful conditions, and hence it becomes imperative to sedate them. Generally, drugs are given to the dogs that are known as sedatives which helps them to stay relaxed and calm.
How to Sedate a Dog for Grooming?
There are many options of sedative drugs available in the market that can be given to the dogs before the grooming sessions. However, it should be seen to it that the sedatives are provided as per the vet's prescription and advice. It is harmful to give your dogs sedatives if you do not have complete knowledge about it. It is also essential to know the quantity of the drug that should be provided for the desired result. All the guidelines should be followed when you are administering such sedatives to your dog.
The sedatives with a prescription should be given in the dosage as per the vet's guideline. The options for sedative drugs for dogs include options like diazepam, acepromazine, etc. Many dog owners have also found the little dosage of Benadryl too helpful for sedating their dogs. The sedatives can be given along with the food to your pet in the small dosages. The food with the sedatives can be given with special treat if your dog is not willing to eat it.
What are the other ways to sedate your dog?
There are other alternative ways to sedate your dogs without giving them the sedatives. As many people do not like to provide their dogs with tranquilizers following tricks also work to calm your furry friend down:
 - Most commonly practiced way to sedate your dog is to take your dog on a walk. Dogs when taken for a walk or any physical activity will get tired. You can also play games such as frisbee with your pet. Playing with them is a great way to make sure that they are not anxious while grooming them with the help of grooming scissors kit. So keeping your dog physically active before taking them to the vet or for a grooming session will help them in being calm during that time.
 - Another way to keep your dog relaxed is to give them their favorite toy or treat when you are grooming them. This will help in distracting your dog attention from grooming to playing with the toy or treat.
 - Dogs crave the most for their owner's touch. Continuously patting them also helps them to calm down. It also helps to calm down their anxiety and restlessness. This way your dog will stay close, and you will be easily able to make them stay stable while grooming them.
 - The last but the most effective method is to try the aromatherapy. There are many natural oils available that help in calming and soothing the animals as well as the dogs down. Such oils are good for the skin as well. One such oil that has soothing effects is Lavender oil. Some drops of lavender oil should be taken on your fingertips and massage it on the back of their head. Rubbing such soothing oils helps the dogs to relax and stay calm. You can also light an aroma candle while grooming your dogs to keep the atmosphere restful.
These all are the ways that are tried and tested to sedate the dogs. If you are giving sedatives make sure it is under vets supervision, also all the other alternative methods are easy to follow.

When were wax cylinders used?
The Edison Phonograph Company was formed on October 8, 1887, to market Edison's machine. He introduced the Improved Phonograph by May of 1888, shortly followed by the Perfected Phonograph. The first wax cylinders Edison used were white and made of ceresin, beeswax, and stearic wax.
What were records originally made of?
Why is vinyl used for records?
Why is it that vinyl records are generally black? PVC (polyvinyl chloride), the material that vinyl records are made of, is clear in its natural form, allowing records to be manufactured in just about any color imaginable.
Does vinyl actually sound better?
Vinyl is far more high-quality. No audio data is lost when pressing a record. It sounds just as great as the producer or band intended. There's another, far superior reason why vinyl is better than lossy digital formats.
Is my record a 33 or 45?
12″ records that are albums (>20 minutes per side) are 33, 12″ records that are singles may be 33 if they are from the US or 45 if they are from Europe. 10″ records are usually 33, but there may be 45 as well.
How long does a gramophone needle last?
Most manufacturers recommend changing your stylus at around 1000 hours of record playing time. So if you're using your turntable for an hour or so per day on average, ideally you should be changing the stylus every couple of years.
How do gramophones work?
Like other record players, gramophones read the sound with a small needle which fits into the groove in the record. That needle is attached to a diaphragm, which in turn is attached to a horn. … These vibrations are transmitted to the diaphragm, which itself vibrates, creating sound.
Are 78s worth anything?
"The early blues material from the '20s and '30s is the hottest material of all," Mr. Tefteller said in a phone interview. He said that on average a rare jazz 78 might sell for $1,500 to $5,000, whereas sales for a comparable blues record would start at $5,000.
What was the first song ever recorded on the phonograph?
Au Clair de la Lune.On April 9, 1860, Scott recorded a snippet of the French folk song "Au Clair de la Lune."
Who invented wax cylinders?
Thomas EdisonPhonograph cylinder/InventorsEdison had introduced wax cylinders that played for nominally 4 minutes (instead of the usual 2) in 1909 under the Amberol brand. They were made from a harder (and more easily breakable) form of wax to withstand the smaller stylus used to play them.
What is the best record player to buy?

Why is tinfoil a poor medium for recorded sound?
The recordings could be played only a few times before the indentations made by the sound on the tinfoil were so flattened down as to be unplayable. … It was changes in the physical medium itself that would ultimately exert the most long-lasting effects on the evolution of American sound recording history.
How does a vinyl record work?
Vinyl record players are electromagnetic devices that change sound vibrations into electrical signals. When a record spins, it creates sound vibrations that get converted into electrical signals. … Electric amps vibrate and feed the resulting sound into speakers, which amplify it and make it louder.

Kealakaha Stream Bridge Replacement
|Client Name:||State of Hawaii, Department of Transportation, Hawaii District|
|Disciplines Applied:||Construction Management|
RMTC provided full construction management services for this FHWA-funded project. All records and documentation were prepared in accordance with FHWA requirements.
Kealakaha Stream gulch is over 600 feet wide and 170 feet deep. The replacement bridge is located makai of existing bridge, and measures 720 feet from abutment to abutment. The existing structure has been declared a Category I Historic Bridge by the State of Hawaii, DLNR Historic Preservation Division. Therefore, no alterations to bridge are permitted and the new bridge must be in addition to the existing structure which has been found to be deficient in width, curvature, sight distance and structural capacity in addition to non-conformance to current federal highway standards.
Kealakaha Stream gulch is over 600 feet wide and 170 feet deep.
The main structural components of the bridge are two box girder piers, one on each side of the gulch. Each pier is supported by eight 5-foot diameter reinforced concrete shafts, each 115 feet in length. These shafts were drilled in the side slope of the gulch such that the tip of each shaft was above the 100 year flood elevations of the stream. The bridge superstructure is supported by Friction Pendulum Seismic Isolation bearings. These bearings are placed at both abutments and at the box girder pier columns to protect the bridge superstructure from earthquake damage. These bearings are designed using the response characteristics of a pendulum. Each bearing consists of an articulated slider plate and a plate with a concave surface. The slider plate is attached to the superstructure and the concave plate is attached to the bridge foundations. During an earthquake, the slider plate slides along the concave surface to dampen the forces of the earthquake.

PRUH launches opt-out HIV testing in Emergency Department
21 April 2022 - The new initiative aims to reduce late diagnoses and improve patient outcomes
Today (Thursday 21 April), the Princess Royal University Hospital (PRUH) launched opt-out HIV testing in its Emergency Department to help reduce the incidence of late HIV diagnosis, encourage those who test positive to receive treatment, and reduce onward transmission of the virus.
Patients attending the Emergency Department who require a blood test as part of their diagnostic care will automatically be tested for HIV unless they specify otherwise.
Those who test positive will be referred to the dedicated HIV team for support and treatment.
Dr Claire Gray, Consultant in Emergency Medicine at the PRUH, said, "The introduction of opt-out HIV testing in the PRUH's Emergency Department is a positive step forward in reducing HIV transmission.
"With the antiretroviral medicines now available, which work by stopping the virus replicating in the body, HIV is a treatable condition and not the death sentence it once was.
"One of the most common reasons people develop complications is because they don't know they have the virus, which this initiative aims to address. Additionally, medical evidence shows that people on effective HIV treatment can't pass on the virus to others."
King's College Hospital in Camberwell, which is part of the same hospital Trust as the PRUH, launched a similar HIV testing initiative in 2016, following funding from the Elton John AIDS Foundation. In the six years since the launch at King's, more than 120 patients who did not know they had the virus have been identified as being HIV positive. These patients have been offered support and treatment from the hospital's HIV service.

12 Types of Children in Ancient India
In Ancient India, 12 types of children were considered to be legal heir of his father. All of them need not be biological children of their legal father.
Manu Smriti and other dharma sastras describe 12 different ways a child can become legal heir of someone.
12 Types of Children in Manu Smriti
When a husband dies childless or is husband is either incapable of fatherhood, wife can opt for a method called 'Niyoga'.
She can request for appointment of a person for helping her bear a child. The man who was appointed must be or would most likely be a revered person. There were various clauses associated with this process, as follows:
1. The woman would agree to this only for the sake of rightfully having a child and not for pleasure.
2. The child, thus born would be considered the child of the husband-wife and not that of the appointed man.
3. The appointed man would not seek any paternal relationship or attachment to this child in the future.
4. To avoid misuse, a man was allowed a maximum of three times in his lifetime to be appointed in such a way.
5. The act will be seen as that of Dharma and while doing so, the man and the wife will have only Dharma in their mind and not passion nor lust. The man will do it as a help to the woman in the name of God, whereas the woman will accept it only to bear the child for herself and her husband.
In niyoga, the bodies were to be covered with ghee (so that lust may not take root in the minds of the participants but the actual act may take place for conception).
In Mahabharata, queen Satyavati compels her first son and sage Vyasa to perform niyoga with the widows of her third son Vichitravirya. The widows Ambika and Ambalika and one of their maids bear Dhritarashtra, Pandu and Vidura respectively.
Manu Smriti describes the child born by niyoga as a kshetraja child of the husband-wife.
12 Types of Children (Legal Heir) in Ancient India
 - Aurasa : Biological son through wife in a normal marriage, where son carries father's Y-Chromosome.
 - Putrikaputra : When there is no son, girl is treated as son and her son becomes legal heir (ex : Babruvahana, born to Arjuna and Chitrangada, but became legal heir of his maternal-grandfather.)
 - Kshetraja : Wife's womb but husband is not biological father. (ex: Kunti, Madri giving birth to pandavas). This can happen even after husband's death and still the children born will be treated as deceased father's heir
 - Dattaka : Adopted through legal method or vedic ritual.
 - Kritima : A child is nourished and brough up as a son, but no adoption rituals performed. Child grows up and assumes you as parent.
 - Gudhaja : Wife's secret son, without husband's knowledge. This child also is heir of father. Only difference with Kshetraja is, husband's approval or knowledge.
 - Apaviddha : Rejected child of some parent, but grew up with others. This child can claim property of person who nourished him, but cannot do pind-daan or death rituals to ancestors of that family (example : Karna did not or could not do pind-daan to ancestors of the adhirtha-radha)
 - Kanina : Son born to a lady before her marriage. But he becomes legal heir of his mother's future husband. (ex : Karna would have inherited the throne of Hastinapur after the death of Pandu being his eldest son as per this law, but birth of Karna was kept secret by Kunti and she revealed the truth only after the death of Karna. )
 - Sahodha : A son is brought along with the marriage. If a woman was pregnant at the time of her marriage, the son born to her after her marriage was deemed to be the son of the man who married her, even though the biological father was a different man.
 - Krita : He is a purchased son.
 - Paunarbhava : The son of a virgin widow. She after her marriage became a 'Punarbhu' ( married second time). Such marriages happened when husband dies during or immediately after marriage and wife is still a virgin. She can re-marry a person of her choice, but a son born from that marriage belongs to the family of 1st deceased husband. She can claim rights only from 2nd kid and so on..
 - Swayamdatta :Self Offered son' – When an orphaned boy went to some person and offered himself to be his son and the latter accepted his offer, the boy in such a case was called Swayamdatta.
Out of above 12, only 3 : Aurasa, Putrikaputra, Paunarbhava were entitled for full property of father and also his family's property (inherited from ancestors).
2 more : Kanina and Sahodha were also given rights to ancestral property, only if their biological father married their mother at a later stage.
Other 7 : Kshetraja, Dattaka, Kritima, Gudhaja, Apaviddha, Krita, Swayamdatta were entitled to claim only what was earned by their (social) father or his part of ancestral property, but not the entire family property. However, they can carry the surname, gotra etc.

How to turn a smartphone into a wireless speaker for your computer
#1
Nowadays, smartphones in general and Android devices in particular, manufacturers developed features and turn it into something that sometimes you do not even think about. For example, in this post, with just a smartphone in your hand, you can turn it into a wireless speaker, connect it remotely with your computer to listen to music or watch movies. This is especially useful when suddenly one day you open up your computer and discover that computer speakers are not working. To make it easy to do, you need an application that bridge the phone and computer called AudioRelay through an internet connection.
Guide to turn your smartphone into a wireless speaker for your PC
To connect your smartphone to a wireless speaker, follow these steps:
Step 1: Get over, go to Google Play store and type in the AudioReplay keyword in the search bar to download the app to your phone. Or, click link below to download the app faster.
Dowload: AudioRelay: Stream audio from PC (Unreleased).
Note that AudioReplay is compatible with Android 5.0 and above and has a relatively small capacity of 7MB only.

So an Internet connection is needed for this? I don't know about you guys, but I don't like giving a website that kind of permission.
I prefer using Soundwire app, it does the the thing by connecting Android phone with PC through WiFi.

Hey, that's actually a nice thing to do. Especially for guys like me, who use the computer more often than their smartphones. It's that I have a speaker for my computer, otherwise I would totally do it. I'll just keep this thread close, in case the speaker dies on me, and I need a new one (or a now cheap and easy replacement).

Mapping documents into an interlingual representation can help bridge the language barrier of a cross-lingual corpus. Previous approaches use aligned documents as training data to learn an interlingual representation, making them sensitive to the domain of the training data. In this paper, we learn an interlingual representation in an unsupervised manner using only a bilingual dictionary. We first use the bilingual dictionary to find candidate document alignments and then use them to find an interlingual representation. Since the candidate alignments are noisy, we develop a robust learning algorithm to learn the interlingual representation. We show that bilingual dictionaries generalize to different domains better: our approach gives better performance than either a word by word translation method or Canonical Correlation Analysis (CCA) trained on a different domain.

Calcium silicate against clay brick masonry: an experimental comparison of the in-plane behaviour during light damage
Research output: Contribution to journalArticleScientificpeer-review
25 Downloads (Pure)
Abstract
The north of the Netherlands is prone to frequent, light earthquakes linked to economical losses and societal unrest due to the induced seismicity in the region. These light earthquakes produce correspondingly low values of in-plane drift on the typical masonry structures of the region, many of which are built with cavity walls composed of an inner, load-bearing calcium-silicate masonry leaf, and an outer, exposed fired-clay masonry veneer. To assess the resulting damage from the lighter earthquakes, it is thus necessary to understand the difference in behaviour of the inner and the outer masonry leaves when exposed to the same drift values. Experimental tests of replicated, full-scale calcium-silicate brick walls and spandrels are detailed herein and compared to previously tested clay masonry samples. A purposely developed, scalar damage parameter is used to assess the width, number and length of the cracks to objectively quantify damage. High resolution digital image correlation is used to accurately monitor the initiation and propagation of cracks. The experiments reveal that calcium-silicate samples exhibit slightly greater damage than clay samples when subjected to the same in-plane drift. From the tests, drift values for light damage or 'damage state one' are set between 0.15 and 0.65‰ for the type of wall tested. Moreover, in these tests, cracks in calcium-silicate samples were significantly more likely to split brick units, whereas cracks in the type of clay samples employed, always followed the masonry joints. This fundamental difference in the light-damage behaviour between the two materials is of importance when considering the perception of damage, the strategies and cost of the repairs, and the strategies for strengthening of masonry structures with cavity walls resembling the type of masonry tested herein.

A A measure of PC gaming performance that includes frame drops.
Average Fps don't tell the whole story. High average Fps can be accompanied by stuttering which results in a poor overall gaming experience. Effective Fps (EFps) measure gaming experience using both average Fps and frame drops. Frame drops are quantified using the following four statistics:
0.1% and 1% Lows (Avg|Max)
To calculate the 0.1% low all the frames in a sample are sorted from slowest to fastest. For a 60 second sample, the frames in the first 0.1%: 60s * 0.1% = 60s/1000 = 0.06s are used to determine the 0.1% low. The average and maximum Fps of those (slowest) frames are the Avg|Max 0.1% lows. A similar calculation is used for the Avg and Max 1% lows. (download example calc spreadsheet )
EFps vs Fps
For most games EFps are similar to average Fps (e.g. GTAV). Where frame delivery is very consistent EFps are higher than average Fps (e.g. Overwatch). Where frames are relatively inconsistent EFps are lower than average Fps (e.g. CSGO). EFps incorporate and improve upon average Fps as a measure of real world playability.
Bottlenecks
PC components are similar to links in a chain: weak components bottleneck the whole system. For example: an AMD Ryzen 3700X bottlenecks an Nvidia 2070 Super. The 3700X costs 40% more money for 11% less performance. The lost performance is similar to downgrading from a 2070S to a 2060S. Publishing EFps data puts UserBenchmark in conflict with the marketing from billion dollar corporations, but it also helps our users to build faster PCs by dodging marketing traps. Users can verify EFps figures with Afterburner

Abstract: This paper describes the application of a multi-perspective object-oriented abstraction in the design of a technical system to address the issues of bounded rationality and to simulate human cognitive coupling. Three major assumptions have been taken in the development of the framework: object representation, classification of objects based on their properties, and bounded rationality. Four rules pertaining to the multi-perspective design method are derived to establish the framework by adopting the function modelling approach. The framework supports the cognitive coupling and uncoupling of multiple perspectives to help designers understand system interactions without suffering cognitive overload. The framework provides guidance for the development of computer tools to support human designers.
Keywords: object-oriented abstraction; multi-perspective abstraction; bounded rationality; design method; function modelling; cognitive coupling; technical system design; object representation; object classification.

Rare glimpse of elusive rail
By Martin Fowlie, Mon, 02/03/2015 – 15:34
An ornithological search-team have caught a glimpse of one of the world's most threatened waterbirds, the Critically Endangered Zapata Rail Cyanolimnas cerverai. The sighting is the first documented in more than four decades and offers hope to conservationists working to ensure its survival.
First described in the early twentieth century, the only nest that has ever been found was by ornithologist James Bond -a name appropriated by Ian Fleming (himself a birder) for 007– and little has since been discovered about its behaviour and breeding ecology. Hopes were fading that viable populations of the Cuban waterbird remained.
The fleeting encounter, now made public, occurred in November 2014. After a series of coordinated surveys of south-west Cuba's Zapata Swamp, ornithologists (including Andy Mitchell and staff from the Cuban Museum of Natural History) struck gold only after deciding to cut thin strips (rides) into the sawgrass to momentarily expose the secretive birds as they moved through the wetland.
"In the first instance, the head protruded from the sawgrass at the side of the ride," recounted Andy Mitchell. "After a few seconds the bird emerged slowly into the open, stopped for a few seconds before moving off into the sawgrass on the other side of the ride."
Now rediscovered, conservation efforts for Zapata Rail will target the wetland in which it was spotted, an Important Bird and Biodiversity Area covering 530,695 ha of wetland in southern Matanzas province. A new project management plan will be developed to assess the species' current population size, distribution and status.
The sighting is the latest victory in BirdLife's Preventing Extinctions Programme, which aims to halt extinctions through rigorous science and practical conservation delivered by a range of partners on the ground.
This music video is called John Zorn – The Zapata Rail.


We're accustomed to touch screens, which are a part of nearly all mobile devices. Touch screens have been in use for a long time. By the mid-1980s, they were fairly standard on digital control systems (DCS), such as those used for refineries and coal power-generating stations.
Small applications have few inputs to change, so the need for a touch screen and its added complications is much less. Thus, thumb switches are widely used because of their simplicity and ruggedness.
What if your thumb switch controls appear not to work? Fortunately, these are easy to troubleshoot.
The first step in this process is to identify whether you have an octal (base 8), binary coded decimal (also called BCD, and it's base 10), or hexadecimal (base 16) system. If you have thumb switches and don't understand these numbering systems, you need to do a little homework.
Your next step is to determine the position of the switch contact for each switch (e.g., up is open). You don't need to test what every combination of switch positions will render, nor do you have enough time to do so. In our next issue, we'll look at how to efficiently test a thumbwheel unit.

This post isn't about "tiled UVs" ("UDIM"), it's about multiple UV sets (layouts).
Polygon mesh models can have multiple UV sets. this becomes useful when the UV layout that is optimal for a certain texture isn't efficient for different texture (in the same material).
For example, we might have a model of furniture, or clothing, in which the UV layout that is best for the fabric weave pattern, isn't the best for dirt and wear & tear, or stickers.
In such cases we can define different UV sets for the model, each suitable for a different texture.
In this example, having a separate UV Set for the logo texture allows placing it without affecting the checker texture that is displayed an all the surfaces:
To create multiple UV sets:
- In the UV editor view, from the UV Sets menu, select UV Set Editor to open the UV Set Editor:
- In the UV Set Editor, press the New button to create a new UV Set and double click it in the list to rename it:
- Close the UV Sets Editor.
The UV Editor view now displays the new UV Set that is empty, and UV creation and editing operations will now affect the new UV Set.
- To switch to edit a different UV Set, select it from the list at the bottom of the UV Sets menu:
To link a texture to a specific UV Set:
- Make sure the texture is connected to the material set for the model.
- Select the model.
- Open Windows > Relationship Editors > UV Linking > Texture-Centric:
- Select the wanted texture from the material texture list on the left and select the wanted UV Set from the models UV Sets list on the right:

By default, the view-ports Camera view in Blender displays the view from the camera that is set as the scene's Active Camera.
If you split the view and in the new view select a different camera and set it as the Active Camera, the view in other view-ports set to camera view will update to display the new Active camera.
In short, by default, it seems you can't assign different camera views to different view-ports..
But you can…
You just have to unlock the wanted view-port from the scene's Active Camera by de-activating this button:
When the Use the scene's Active Camera and layers in this view button is de-activated, your allowed to set an Active Camera for the specific view-port without changing the scene's Active Camera setting, therefore not affecting other view-ports displaying the camera view.
Use the Select Pattern tool to select multiple objects with name similarities.
- In the 3D View in Object mode choose Select > Select Pattern…
- In the Select Pattern dialog, type a part of a name with an Asterisk to define wild cards.
For example *car* will select all objects who's names contain the string 'car',
And car* will select all objects who's names begin with the string 'car'.
To remove all the selected objects from all Groups:
Press Shift + Ctrl + Alt + G
1) Select multiple objects
2) Alt + Click wanted parameter and change it
1) Select multiple objects
2) Set the wanted parameter
3) right click parameter and choose 'Copy To Selected'
* Do the same for grouped parameters like vectors using 'Copy All To Selected'

WindTracker and WindLogger comparison / difference
LeWL WindLogger Vs WindTracker
Logic Energy's WindLogger (LeWL) and WindTracker are compact, self-contained and robust loggers both designed for wind data collection and recording. They are used for small scale wind turbine site assessment up to around 15 metres hub height. The devices are broadly similar in function, but differ in terms of:
- Wind data calculation and manipulation
- Wind data recording and presentation
The WindLogger can be configured for different recording intervals and anemometers, and gives a complete timestamped data set for use in analysis software. The WindLogger comes with simple report and analysis software and spreadsheet, but other analysis software can also be used.
The main features are:
- Recording intervals of 1 minute or 10 minutes.
- Records data for 2 anemometers (speed) and 1 wind vane (direction).
- Time-stamped data for each interval includes average, maximum, and standard deviation of wind speed; average wind direction; and internal temperature.
- Data stored on SD memory card in standard CSV data file, suitable for import into spreadsheet or wind analysis software.
- Logger comes with SD card, and contains setup software, user guide and analysis tools.
- Logger can be configured from PC using a setup utility or serial port terminal.
The WindTracker is a simple but effective wind data logger that requires very little setup and allows you to generate a wind data report with minimum effort.
The main features are:
- Measures speed and direction for 1 anemometer and 1 wind vane.
- Continuously samples speed/direction. Updates internal statistics each hour.
- Writes current data to SD memory card on demand (insert the card to get new data). Each wind report contains a summary of the site wind profile for the entire monitoring period.
- Wind data summary is stored in a compact file that can be uploaded to the wind report generator on the Logic Energy website to create a graphical wind report.
- Wind report data includes:
- Average wind speed.
- Wind Speed Frequency Distribution – shows how often the wind speed wind reaches specific values (12 speed bands/bins from 2 to 13+ m/s).
- Average wind direction for each wind speed band (based on 16 direction bins).
- WindTracker comes with SD memory card and contains instructions. SD card is just used to configure the device and collect wind data, and should not be permanently left in the device.

Shadow-free light guaranteed. Unlike traditional multi-bulb surgical lights, HyLite 6 series produces light with perfect shadow reduction. It achieves this using only one bulb attached to a parabolic reflector composed of thousands of facets which function like miniature mirrors. Every facet receives light and projects it onto the operating field. Light rays projected from every facet make up a light column that is uniformly projected on every corner of the operating field, thus ensuring a shadowless field, even if a surgeon is standing directly under the light.
 - HyLite generates minimized disturbance in two ways: firstly, it features a smooth outline that hides the encircling grips; secondly, it consumes so little power that the warming effect on the outer surface is extremely low
 - HyLite employs a state-of-the-art reflector to produce a perfect light column that presents a depth of illumination up to 1,200mm (L1+L2, as defined by IEC 60601-2-41)
 - HyLite has two identical bulbs, one in operation and the other standing by. If the bulb in use fails, HyLite will switch to the backup bulb in 0.2 seconds and and move it into the working position. A surgeon will not perceive any difference in either illumination or light field center


Effective antifreeze method of solar water heater in winter

Effective antifreeze method of solar water heater in winter
In winter, for customers who use water heaters, the most fear is that the temperature is too low to cause the water heater to freeze. How to effectively avoid freezing and how to solve the icing problem?
1. First of all, when the winter enters, we must first check the pipes of the solar water heaters. Pay attention to whether the screws at the pipe joints are loose, whether the pipes are cracked, disconnected, or leaked. If there are any, we must pay attention. service.
2. Take good insulation measures
1. For solar energy pipelines, it is best to wrap them with foam, cotton and linen fabrics, plastics, etc., which can play a role in heat preservation.
2. General solar water heaters have electric heating cables. When the temperature is lower than zero, remember to turn on the electric heating cables to protect the solar water heaters from freezing.
3. Dripping antifreeze
As long as the water keeps flowing, there is little chance of being frozen. Before going to bed at night, you can slightly turn on the hot water faucet to let the water drop and ensure the water flows in the pipe. Remember to put a bucket to catch the water, and it can be used the next day. Don't waste water.
4. Emptying and antifreeze
Because the previous method may cause a waste of water resources, I will recommend another method for you. When the temperature is particularly low or solar energy is not used for a long time, the original water in the solar water heater should be caught with a bucket and drained. In this way, there is no water in the water pipe, and naturally it will not freeze.
5. Pay attention to choosing the time of Sheung Shui
The use of solar water heaters in winter needs to determine the time to add water according to weather conditions. If the outdoor temperature is above zero, consider adding water that night; if the outdoor temperature is below zero, it is best to add water the next morning to prevent the water outlet from being frozen.
6. The method of thawing
If the solar water heater is frozen, how can it be defrosted quickly and safely?
1. There is electric heating on the water heater, just turn on the electric heating directly.
2. For hot water pipes that have been frozen, you can use warm water to thaw them. Do not use hot water or directly hit the pipes! Doing so may cause the pipeline to burst directly.
The above are some tips for anti-freezing water heaters, I hope it will be helpful to you who have this problem.

Science on the farm is fun, and our rocks and soils workshops allows children to touch and squish soil, and work out what it is composed of. Children will find out why soil is so important to farmers, learn about different types of soils, and take part in experiments.
In the Barleylands kitchen, children can create an edible soil horizon using sweets, and biscuits to take back to school. Alternatively, the children can create healthy pizzas in the kitchen, learning about foodstuffs grown in our polytunnel. After all, without soil, we would have no food!

Arts & Culture: The Timken Museum of Art, which is located in beautiful downtown San Diego, Calif., is the permanent home of the acclaimed Putman Foundation Collection. The collection consists of paintings of European, American, and Russian artists acquired by Amy and Anne R. Putman. The Putnam sisters are heiresses of the Timken Company, which is the world's largest manufacturer of tapered roller bearings and mechanical seamless steel tubing. The firm was among the first to produce roller bearings for railroad cars.
A majority of the sisters' collection consists of artwork dating back to the 15th century. George Inness, Thomas Birch, and Benjamin West are some of the painters of the American Collection. Franz Hals, Gabriel Metsu, and Nicolaes Maes represent work of the Dutch/Flemish Collection. Collections of French and Italian artists include paintings of Claude Lorrain and Bartolomeo Veneto, respectively.
Some of the displayed artwork dates back to the 15th century. The Return of the Prodigal Son, Portrait of a Lady in a Green Dress, Still Life, Portrait of a Lady, and A View of Haarlem and Bleaching Fields serve as excellent representative samples of the masters' works permanently exhibited at the Timken.
Paintings from the elaborate Putnam Foundation Collection were loaned to museums worldwide until 1965, when the Timken Museum of Art opened its doors. Numerous paintings of the collection were on loan to esteemed museums, such as the Metropolitan Museum of Art in New York City, the National Gallery in Washington, DC, and the Fogg Art Museum of Harvard University.
The Timken Museum of Art is located close to the San Diego Museum of Art in San Diego's scenic Balboa Park.

The Australian Standard Drink
What is a standard drink?
A standard drink is a unit of measurement. In the same way one metre measures a particular distance travelled, one standard drink measures a particular amount of alcohol consumed.
What is the standard drink used for?
Instead of counting glasses or containers, drinkers count standard drinks as a way of keeping track of how much alcohol they consume. Counting standard drinks is a much more reliable measure of how much alcohol is consumed compared to counting glasses, bottles, or cans. Counting glasses, bottles, or cans of alcohol can be misleading because they can contain varying amounts of alcohol.
The consumption limits in the Australian Alcohol Guidelines are based on the standard drink concept.
How many standard drinks in....?
The number of standard drinks in alcohol beverages is always shown on the label of the container.
Examples of how many standard drinks are in typical containers, always check the label or ask bar staff
Standard drinks guide
No label?
Bar and restaurant staff can help in identifying how many standard drinks are in glasses, jugs, and other containers that are not labelled. Restaurants and bars do not all have the same size glasses, so the number of standard drinks can vary from one licensed venue to the next.
How are standard drinks calculated?
The formula for calculating standard drinks is:
Volume of Container in Litres multiplied by the percentage of alcohol volume multiplied by 0.789, equals the number of standard drinks
0.789 is the specific gravity of ethyl alcohol
For example one stubbie of 375ml of full strength beer 5% alcohol by volume:
0.375 multiplied by 5 multiplied by 0.789 equals 1.5 standard drinks
0.375 X 5 X 0.789 = 1.5 standard drinks
How to count Standard Drinks?
Counting standard drinks is simply a matter of adding numbers.
For example if a person has one nip of spirits and two average restaurant glasses of wine, they would have consumed 4 standard drinks, that is 1 + 1.5 + 1.5
An average serve of wine is usually 150ml. Depending on the venue, glass size can vary from 120 to 180ml.
Some people put a bottle cap or a coaster in their pockets to represent every drink they have. This is not as accurate as counting standard drinks but it is better than not counting.
When counting standard drinks, people should be aware of bar staff or others topping up glasses or where the amount of alcohol is not known such as in mixed drinks, cocktails or punch.
Why count?
The main reason people count their drinks, using standard drinks, is to ensure that the low risk levels set out in the Australian Alcohol Guidelines are not exceeded. The low risk levels define the number of standard drinks that can be drunk before the threat to a person's health and social well-being moves up into the risky or high risk category.
