Rails GetText Syntax Overview
In this article, we will give you a quick overview of how to translate your Rails application with the GetText syntax. There is only a few (short-named) methods to remember, we will make you love underscores!
TL;DR
Singular _("text")
Plural n_("singular text", "plural text", number)
Singular with context p_("context", "text")
Plural with context np_("context", "singular text", "plural text", number)
Simple Texts
_ is the base method you will use everywhere.
In a controller :
class PostsController < ActionController::Base
 def create
 ...
 flash[:notice] = _('Post successfuly saved')
 redirect_to posts_path
 end
end
In a view :

<%= _('Create a New Post') %>

<%= f.label :title, _('Title') %>
In a model validation :
class Post < ActiveRecord::Base
 validates :title, :presence => {
 :message => lambda { _('Title is mandatory.') }
 }
end
Note that the call was wrapped into a lambda because otherwhise it would have been statically evaluated.
Interpolations
Interpolations can be easily performed using the standard % operator. Find some examples below.
_('Hi %{name}, do you like violence?') % { name: "Steve" }
_('%{city1} is bigger than %{city2}') % { city1: "NYC", city2: "BXL" }
Plural Forms
If the translatable string is depending on the number of items, use _n. It takes three arguments : the singular form, the plural form, and the cardinality.
For example :
n_("There is a mouse in our house.", "There are some mice in our house.", @mice.size)
And you can of course combine with interpolations :
n_("There is a mouse.", "There are %{num} mice.", @mice.size) % { num: @mice.size }
Translation Contexts
Sometimes you would need to scope a given translation to a given part of you application. For instance in order to be able to translate a given string differently depending on the context.
There are two dedicated methods for that : p_ (singular with context) and np_ (plural with context). They take the same arguments as _ and n_ (respectively) with an extra string argument defining the context added before.
Here is an example :
p_("Menu", "Open file")
p_("Menu", "Close file")
With plurals and interpolations :
np_("Menu", "Open a file", "Open %{n} files", 4) % { n: 4 }
If you are wondering why it is p for defining a context, that is because it stands for prefix.
Other Syntaxes
Some other special usages of GetText can also be used but won't be detailed here because they are very specific (and not so useful) : s_, ns_, N_ and Nn_.

Skill Builder: Annotated OutlineAn outline is the scaffold upon which you build your paper. You probably already use a mental outline when you plan a paper, perhaps without even being aware of it. Writing the outline can give you a visualization of your plan. An outline provides both focus and direction for the paper, shows where relevant points and arguments need to be made and also identifies areas where more supportive evidence is needed.What is an annotated outline?Because you are writing a research paper, your paper is built around the research findings that you located in your search.When you prepare an annotated outline, you will note the research that supports each section of the paper. This will help you see any areas that need further research to support them.The following example may help support the transition of your paper from a collection of research notes to a fully developed paper.Suppose the research topic you chose was the relation of childhood bullying to self-esteem. The title of your paper is: Self-esteem in childhood bullying.When researching the paper, you found conflicting research results. Some research showed that children with low self-esteem tended to bully others, while other research showed that children with extremely high self-esteem were bullies. Looking closer, you began to see that this research could be divided into studies investigating different variables, such as gender, age, and ethnic background. Now, you want to turn this into a research report.An annotated outline might look like this (all citations are fictional):Topic: The relation of childhood bullying to self-esteem: Too much or too little?Overview of childhood bullyingDefinitions of bullying (Simpson, 2010; O'Connor, 2008)Types of bullying (Yang, 2009; Sinisi, 2011)Self-esteem in childhoodDefinitions of self-esteem (Whitefield, 2009)Impact of self-esteem on behavior in childhood (Liebermann, 2010)Research on the relation of self-esteem to bullying in childhoodGender, self-esteem, and childhood bullyingSelf-esteem and same-gender bullyingSelf-esteem in boys bullying boys (Pryzborski, 2012)Self-esteem in girls bullying girlsSelf-esteem in opposite-gender or non-gender specific bullying in childhood (no research found)Age, self-esteem in childhood bullyingSelf-esteem and bullying from 6-9 (Brennan, 2011)Self-esteem and bullying from 9-12 (Mendez, 2010; Lee, 2011)Family structure, self-esteem, and childhoodSelf-esteem and bullying in children in single-parent families (Shams, 2012)Self-esteem and bulling in children in dual-parent families (Mugaddam, 2011)Ethnicity, self-esteem and childhood bullyingInter-ethnic bullying and self-esteem (Jacinto, 2009; Akbarzadeh, 2010)Intra-ethnic bullying and self-esteem (Lawrence, 2011)ConclusionsSummary and suggestions for future studiesReferencesPreparing an annotated outline in this way will give you a way to organize and clarify your plans. Additionally, it gives your instructor a chance to provide feedback on the proposed structure of the paper before you begin to write. You can also see which subtopics you need to research further before proceeding with the final draft.AssignmentThis week, you will develop an annotated outline that will help support the transition of your paper from a collection of research notes to a full-blown paper. Preparing an annotated outline in this way will give you a way to organize and clarify your plans and allow your instructor a chance to give you feedback on the proposed structure of the paper before you begin to write it. You can also see which subtopics you need to research further before proceeding with the final draft.One way of talking about outlines is to describe an outline as a pre-writing outline, or as a reverse outline. The prewriting outline is prepared before the paper is written, so you can see the plan you want to follow. Some people, however, must write their ideas out before they take shape; if that is your preferred approach, you can use a reverse outline method. Write out a draft, then go back and try to outline it. If you cannot find the structure in your paper, then you probably need to do some serious revisions. Think of a pre-writing outline as scaffolding, and a reverse outline as an X-ray of your paper.When you prepare an annotated outline, you will note the research that supports each section of the paper. This will help you see any areas that need further research to support them.Here are some great resources, located under your weekly resources, for Reverse Outlining:Purdue Online Writing Lab: Reverse OutliningUNC, The Writing Center: Reverse OutlineSupport your work with at least 10 peer-reviewed research articles published in the past five years.Length: 2-3 pages, plus reference list in proper APA formatYour outline should demonstrate thoughtful consideration of the ideas and concepts that are presented in the course and provide new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards. Be sure to adhere to Northcentral University's Academic Integrity Policy.Upload your document and click the Submit to Dropbox button.

The 2020 Production Assistant Jobs Report
We surveyed different production assistant jobs to better understand the current state of the industry for career seekers.
So if you've been looking for how to get a film production assistant job and profit from the movie industry, this article is for you.
In this report you'll learn:
 - How much production assistants earn.
 - Duties and responsibilities of a production assistant.
 - Basic skills, education, and certification required to become a production assistant.
 - Why people decide to become production assistants.
 - Lots more.
So without further ado, let's get right in.
Who is a Production Assistant (PA)?
A production assistant is a member of a film crew usually attached to individual actors or filmmakers to carry out odd jobs and support tasks in the process of production.
Production assistant jobs are basically entry-level jobs within the film production industry. It is the first step to a long career in Hollywood and movie production in general.
PAs do the jobs that no one else wants to do in a movie production set!
Here's a shortlist of some odd jobs a production assistant could be assigned to do:
 - Organizing food or catering
 - Making copies of movie scripts
 - Managing paperwork (contracts, scripts, timesheets, etc.)
 - Controlling crowds and fans
 - Answering important phone calls
 - Moving equipment around
 - Transporting casts and crews between locations
 - Many more…
Why Do People Decide to Become Production Assistants?
film production assistant job
From our recent survey, we were able to discover the following as major reasons why people decide to become production assistants:
1. The Love of Media
Most people aim at getting a production assistant job just because they are passionate about a particular medium (movie, TV or radio).
Randolph Bookman once stated in his article titled: Being a Production Assistant that:
It was a love of the film industry that drew him closer to his job as a film production assistant.
Randy is now a producer/production manager known for his works on Forced Alliance (2007), Poseidon (2006) and Terminator 3 (2003).
2. Connecting with Talents
Becoming a production assistant creates an opportunity to connect with top celebrities in the film production industry.
And it doesn't have to be all about connecting with celebrities!
Production assistants also have the chance to work with leading film producers and directors.
3. Learning the Craft
This is one of the major reasons why people decide to take-up production assistant jobs.
The willingness to view the job as a hand-on education is a huge advantage for every production assistant.
4. Union Benefits
Randy also pointed out that the job of a production assistant is part of a union with strong benefits attached, and protection against termination without cause.
Also, a production assistant may earn some residual income especially on movies or shows that earn a significant income.
Working as a production assistant is a great way to get to know all the various departments on a movie set and figure out what a person wants to do. It's also an excellent way to finally getting hired in those departments.
No matter what you think, there's little glory attached for being a production assistant.
But, is it really that easy to get a production assistant job?
Basic Skills and Requirements to Become a Production Assistant
The good news about production assistant jobs is that they are all entry-level positions and require the least number of years of experience.
Education, Certification, and Training
Production assistant jobs don't necessarily require a particular educational background or qualification.
But in order to be a bit ahead of your other job applicants, you may require an associate's or bachelor's degree with classes like theater, television and film production, communications, or an artistic field such as graphic design or costume would be helpful.
But basically, the minimal level of education you may require is a high school diploma or GED.
While working as a production assistant, you can work to prepare yourself for a better position. You can take up other side-gigs like working for your college radio station, local television stations or signup for internship programs.
You can also learn more about the movie industry business by participating in production assistant boot camps.
All these will help to expand your knowledge of filmmaking and learn how to handle different positions in the industry.
Required Skills
Although your level of education isn't a major criterion when applying for a production assistant job, recruiters still lookout for certain skills to qualify an applicant.
These skills include:
1. A good listener
Normally speaking, no employer likes to have to repeat themselves. So, for you to become a production assistant you must be a really good listener at all times, listening to the directions you are given.
2. Responsibility
Production assistants are really easy to replace.
So for you to retain your production assistant job, you must be really hardworking and try as much as possible not to be late and lazy at work.
3. Social skills
Surprisingly, this is one of the most important parts of a production assistant's job description.
Anyone working in the entertainment or film industry will at some point of his career comes to deal with some eccentric personalities. And for production assistant jobs, you need to be extra kind, polite and hospitable.
You also need to have confidence in yourself not to back down just because a director tries to bully you.
Your social skills will also be helpful in getting new jobs and moving your career up the ladder.
The movie industry is more about who you know to help you move forward. So, you will need to really put yourself out there, attend networking events, join as many Facebook groups as possible just to create a reliable network for your future gigs.
4. Always willing to learn
Production assistants are there to help and not become an obstacle to the completion of a film production process. Do as much as you can to learn more about every job on the set without getting in the way.
You are there as a production assistant both to help and to learn. Be open-minded to whatever you're asked to do on the set.
5. Patience
You must understand that it takes time to grow. And once you're the best at what you do, someone will definitely notice you.
N.B: A driver's license and clean driving record may be required of you because production assistant jobs often require you to make deliveries and run errands.

text: Since surfactants reduce the interfacial tension of immiscible liquids by forming micelles through hy-drophobic and hydrophilic groups in their structure, they are frequently used in different fields of analytical chemistry. The use of surfactants in analytical techniques continues to increase from past to present. They are used in chromatography to improve separation efficiency and reduce the amount of organic solvent. In electrochemical techniques, they have important functions such as increasing the selectivity and sensitivity of the sensor in the supporting electrolyte or as an electrode modifying agent. The use of surfactants in these techniques, as well as in capillary electrophoresis and sample preparation, draws attention. This review summarizes the recent applications of surfactants in these analytical techniques, along with their primary usage in chromatography, capillary electrophoresis, and electro-chemical analysis. Moreover, this review also describes the structural properties of surfactants and the advantages of their use in these analytical techniques. (c) 2021 Elsevier B.V. All rights reserved.

Ugu vegetable, botanically known as Telfaria occidentalis is an indigenous vegetable crop in Africa; it is also called fluted pumpkin. Ugu plant is cultivated for its leaves; it is a major part of African delicacies. The commercial cultivation of Ugu is so lucrative as Ugu vegetable is a short term cash flow crop that requires little or no capital to cultivate.
Prior to the establishment of ugu farm, I do encourage intending farmers to seek adequate knowledge to avoid any unfortunate experiences. Aside from authoring the ebook on ugu farming, I found it crucial to share these practical guides and insights to enable successful cultivation. In this article, you would learn the production practices for fluted pumpkin, cost analysis of ugu farming, how to make ugu farm bed, fertilizer requirements and best fertilizer for Ugu, marketing strategies, and storage of Ugu in raw and dried form.
How To Establish Ugu Farm
Every farm establishment has preplanting and postplanting operations; the establishement of ugu farm is also made up of preplanting and postplanting operations that must be carried out adequately to ensure a profitable operation. There are basically 7 steps in establishing a successful commercial ugu farm, namely;
- Site selection.
- Land preparation.
- Pre-planting operation.
- Planting operation.
- Seed germination.
- Post planting operations.
#1. Site selection: Type Of Soil Ugu Grow Better On
Crops have different preferences for the type and nature of soil they grow on; the type of soil to grow ugu for good performance is a well-drained loamy soil that is rich in organic matter with a neutral pH. A waterlogged soil does not support the growth of ugu.
#2. Land preparation for ugu farming
Prior to planting ugu vegetable, the land has to be prepared using various land preparation methods. For commercial cultivation, I would recommend a conventional land preparation method where the land is ploughed twice and later harrowed to aid better rooting medium and allows the free flow of growth parameters such as air, water, nutrients and dissolved gases. Organic manure can be added into the soil during the second ploughing to facilitate the mineralization of the manure prior to sowing of the ugu seeds. Land preparation for ugu farming makes the making of beds very easy to achieve.
#3. Making of beds for Ugu planting
One of the purposes of land preparation in ugu farming is to ease the operation of the planting medium, the ugu vegetable beds. Crops are planted in different planting medium, some are planted on flat, ridges and beds. As for ugu, it is best planted on beds. In this guide, you would learn how to make ugu farm bed to facilitate good growth.
Ugu are best planted on raised beds of either 5 by 5 meters or 1wide by 10 meters long. The soil is raised to prevent the washing away by erosion and also provide a better feeding area of the emerging seeds. The bed must be spaced enough to allow the carrying out of various agronomic practices on the ugu farm such as weeding, watering, fertilizer application and harvesting. The inter-spacing between the ugu beds must be as wide as 0.5 meters.
#4. Seed treatment for Ugu seeds
It is not proper to plant fresh ugu seeds immediately after extraction from the pods. The ugu seeds have to go through series of treatment to make them assume germination as soon as they are planted. Firstly, after extracting the seeds from the pods, the seeds are air-dried. Do not sundry ugu seeds. Airdry the seed to reduce its moisture content before planting.
After air-dyring for about 24 hours, scarification must be done for the seeds to germinate rapidly. Usually ugu seeds germinate in about 10-15days but scarified ugu seeds germinate in less than 10 days. Scarification of the ugu seeds means bruising of the seed coat; this can be done with sands. Simply place a handful of seeds in your hand with sand in between and rub gently to bruise the seed coats. After extracting the seeds, the seed can be treated with insecticide-fungicide mixture such as Apron plus or Seedrex to prevent the seeds from insects and fungi attack.
#5. How to plant Ugu seeds
Planting ugu seeds is a technical operation as one must be careful to ensure the right side is inserted into the soil. When the seeds are successfully dried up, a pointed edge is noticed at the top of the seeds. This pointed edge is the portion that must be inserted into the soil at a depth of 3-5cm. Any mistake in the mode of planting could adversely affect the emergence of the seedlings. The pointed edge should be identified and ensure it points downward during planting. The seeds can be planted using different planting methods, namely:
- Dibbling method: In this method, the soil is just scooped and the seeds are inserted into the soil. The soil is not pulverized or tilled.
- Planting on beds: In this method, nursery beds are constructed, the land is tilled and pulverized . Raised beds are constructed across the slope of the land to reduce the risk of erosion.
Well-treated Ugu seeds would germinate at about 10 days to 12 days after planting.
#6. Spacing for planting ugu
The spacing for Ugu is not the same as other vegetable crops. The best spacing for ugu is 1 meter by 1 meter if planted directly into the soil. However, if the seeds are planted on beds, the spacing between the beds should be 0.5meter and the spacing between the ugu seeds on the beds should be 1m by 0.75m
Agronomic Practices Carried Out On Ugu Farm
After the planting and emergence of the seedlings, there are certain post-planting operations that must be done to salvage the seedlings to harvesting period, they include;
#1. Watering of Ugu vegetable
The seedlings have to be watered daily for the first two weeks of emergence to enable them to grow well.
#2. Weeding of ugu farm
Weeds have to be managed to guide against the competition on water, nutrients etc. with the seedlings. Weeding should be done every two weeks.
#3. Fertilizer application on Ugu
A nitrogenous fertilizer such as urea is the best fertilizer for ugu; because ugu is a leafy plant and such fertilizer enhances the growth of the vegetative parts or leaves of the plant. However, NPK 15:15:15 could be applied.
#4. Staking of Ugu plant:
Staking is not encouraged in commercial ugu farm as it distorts the growth habit and could reduce the potential yield on the farm.
#5. Control of pest in ugu farm
Pests such as leaf defoliators and some pathogenic infections are often noticed. This can be controlled biologically by boiling neem leaves (Dongoyaro) and spraying the extracts in the leaves for a period of two weeks.
#6. Harvesting of ugu
Ugu can be harvested after about 30 days of planting. The more the harvest the better the yield of the leaves in terms of size. Ugu can be harvested repeatedly for about eight months at an interval of 15 days. You need to know how to harvest ugu so that you do not trample on the fruits (pods) as they emerge. The safest way of harvesting Ugu is to pick up a long vine and inspect for the fruits (pods); the spot of the emerging seed should be the spot to stop the harvest.
#7. Storage of Ugu
Ugu vegetable is a perishable vegetable that can be stored fresh for a little period. After harvesting, Ugu can be stored in a cool room preferably a shelf or rack. Water must be sprinkled on the vegetable intermittently on the shelf. Placing ugu on bare floor can lead to rotting and rapid spoilage of the vegetable. Alternatively, ugu can be dried at room temperature to for longer storage. All you need to do is to clean the vegetable and air-dry till it becomes crispy. This does not reduce its nutritional value in any way.
Ugu farming is a very lucrative agribusiness that is capable of giving immediate returns on investment within a short period. I would recommend you purchase this Ugu farming PDF for better guide towards your cultivation. It goes for just #2000. Place your order

Use Messages in Test Sequences
Messages carry data between Test Sequence blocks and other blocks such as Stateflow® charts. Messages can be used to model asynchronous events. A message is queued until you evaluate it, which removes it from the queue. You can use messages and message data inside a test sequence. The message remains valid until you forward it, or the time step ends. For more information, see Messages in the Stateflow® documentation.
Receive Messages and Access Message Data
If your Test Sequence block has a message input, you can use queued messages in test sequence actions or transitions. Use the receive command before accessing message data or forwarding a message.
To create a message input, hover over Input in the Symbols sidebar, click the add message icon, and enter the message name.
receive(M) determines whether a message is present in the input queue M, and removes the message from the queue. receive(M) returns true if a message is in the queue, and false if not. Once the message is received, you can access the message data using the dot notation, M.data, or forward the message. The message is valid until it is forwarded or the current time step ends.
The order of message removal depends on the queue type. Set the queue type using the message properties dialog box. In the Symbols sidebar, click the edit icon next to the message input, and select the Queue type. For more information see Queuing Behavior of Stateflow Messages.
To send a message, create a message output and use the send command. To create a message output, hover over Output in the Symbols sidebar, click the add message icon, and enter the message name.
You can assign data to the message using the dot notation M.data, where M is the message output of the Test Sequence block. send(M) sends the message.
You can forward a message from an input message queue to an output port. To forward a message:
- Receive the message from the input queue using receive.
- Forward the message using the command forward(M,M_out) where M is the message input queue and M_out is the message output.
Compare Test Sequences Using Data and Messages
This example demonstrates message inputs and outputs, sending, and receiving a message. The model compares two pairs of test sequences. Each pair is comprised of a sending and receiving test sequence block. The first pair sends and receives data, and the second sends and receives a message.
Set the following path and model name variables.
filePath = fullfile(matlabroot,'examples','simulinktest'); model ='sltest_testsequence_data_vs_message';
Open the model.
Test Sequences Using Data
The DataSender block assigns a value to a data output M.
The DataReceiver block waits 3 seconds, then transitions to step S2. Step S2 transitions to step S3 using a condition comparing M to the expected value, and does the same for S3 to S4.
Test Sequences Using Messages
The MessageSender block assigns a value to the message data of a message output M_out, then sends the message to the MessageReceiver block.
The MessageReceiver block waits 3 seconds, then transitions to step S2. Step S2's transition evaluates the queue M with receive(M), removing the message from the queue. receive(M) returns true since the message is present. M.data == 3.5 compares the message data to the expected value. The statement is true, and the sequence transitions to step S3.
When step S3's transition condition evaluates, no messages are present in the queue. Therefore, S3 does not transition to S4.
Run the test and observe the output comparing the different behaviors of the test sequence pairs.

Return num cryptographically strong pseudo-random bytes. Raises an SSLError if the PRNG has not been seeded with enough data or if the operation is not supported by the current RAND method. RAND_status() can be used to check the status of the PRNG and RAND_add() can be used to seed the PRNG.
For almost all applications os.urandom() is preferable.
Read the Wikipedia article, Cryptographically secure pseudorandom number generator (CSPRNG), to get the requirements of a cryptographically generator.
New in version 3.3.
ssl.RAND_pseudo_bytes(num)
Return (bytes, is_cryptographic): bytes are num pseudo-random bytes, is_cryptographic is True if the bytes generated are cryptographically strong. Raises an SSLError if the operation is not supported by the current RAND method.
Generated pseudo-random byte sequences will be unique if they are of sufficient length, but are not necessarily unpredictable. They can be used for non-cryptographic purposes and for certain purposes in cryptographic protocols, but usually not for key generation etc.
For almost all applications os.urandom() is preferable.
New in version 3.3.
Read again; see what it says? right, it says: For almost all applications os.urandom() is preferable. Because only a complete amateur would use other third-party APIs in Python for randomness.
I think I'm officially giving up on this one. Four months ago I warned the Ruby Core team that a bug in the OpenSSL PRNG can cause security problems for Ruby proper. This has happened of course. Still the team thinks it's a better approach to use a userland RNG instead of the one provided (and well maintained) in the respective kernels and accessible via system calls.
I'm a long-time Ruby developer, but I think I will never use Ruby again for any security-critical code parts. This reminds me of API discussions we had for PHP4 years back and just makes me sad. Expect weaponized exploits to full-disclosure lists in the future, your bug-tracker is obviously useless.
So long. And thanks for all the fishy crypto.
#25 [ruby-core:75339] Updated by Scott Arciszewski 25 days ago
Let's look at some OpenSSL RNG failures outside the Ruby microcosm:
If you're still dead set on using OpenSSL for a RNG, just know that when people say things like _URL_ about PHP being insecure, it applies tenfold to Ruby because of everyone's stubborn refusal to fix their RNG.
To wit (here's a CSPRNG done right): _URL_
#26 [ruby-core:75340] Updated by Eric Wong 25 days ago
Has anybody here brought up the issue to the OpenSSL team to get
OpenSSL fixed?
Fixing OpenSSL would benefit far more people than just working
around the problem in Ruby.
I'm definitely no expert on RNGs, but when I encounter bugs in
other software; I try to get it fixed at the source rather than
working problems at a higher level.

And on that bug, the speed issue was mentioned, too, like at _URL_
So I see several ways forward for this:
1) Get OpenSSL to fix it. It would definitely benefit more people than just Ruby users.
2) Convince Ruby committers that urandom can be used without speed problems on all relevant platforms and for all relevant application.
#29 [ruby-core:75343] Updated by Delan Azabani 25 days ago
For anyone reading this thread after me:
 - SecureRandom.gen_random calls OpenSSL::Random.random_bytes before falling back on Random.raw_seed [1]
 - Random.raw_seed calls fill_random_bytes [2]
 - fill_random_bytes calls fill_random_bytes_syscall before falling back on fill_random_bytes_urandom [3]
 - fill_random_bytes_syscall is compiled to wrap CryptGenRandom if available, falling back on getrandom(2) [4]
 - fill_random_bytes_urandom reads from /dev/urandom if it considers the device reasonable [5]
It's good to see that fill_random_bytes already prefers getrandom(2) over /dev/urandom, as getrandom(2) blocks only if it has been called so early in the boot process that there isn't enough initial entropy [6], and it isn't susceptible to file descriptor exhaustion attacks [7].
Changing the order of SecureRandom.gen_random should be enough to fix this bug, but I would also suggest adding arc4random(3) [8] or getentropy(2) [9] to the collection of methods tried by fill_random_bytes_syscall, which will mitigate file descriptor exhaustion attacks for OpenBSD users.

Nothing needs to be done on OpenBSD, since SecureRandom.random_bytes uses OpenSSL::Random.random_bytes, which calls RAND_bytes(3). OpenBSD uses LibreSSL, which on OpenBSD has RAND_bytes(3) call arc4random_buf(3) which calls getentropy(2). OpenBSD's libssl already mitigates file descriptor exhaustion attacks.

I think switching OpenSSL to getrandom() is possible if the performance is acceptable.
The man page for getrandom(),

OpenBSD's getentropy() has limitation on buffer size: 256 bytes.

Some gems use SecureRandom.random_bytes(more-than-256).

Cell axial pressurization fans play a vital role in creating a well-ventilated environment. They are commonly used in various industries, including manufacturing, agriculture, and construction. This article will cover everything you need to know about cell axial pressurization fans, including how they work, their benefits, and the different types available.
What are cell axial pressurization fans?
Cell axial pressurization fans are high-volume, low-pressure fans designed to create positive pressure within a building or enclosed space. They are used to improve ventilation and control the air quality of the area. The fans work by drawing in fresh air from outside and pushing out stale air. The positive pressure created by the fans can also prevent contaminants, such as dust, smoke, or fumes, from entering the space.
How do cell axial pressurization fans work?
Cell axial pressurization fans work by creating positive pressure within the building or enclosed space. The fans are typically installed in the exterior walls of the building, and they are connected to ducts that draw in fresh air from outside. The fans then push this fresh air into the building, creating positive pressure that helps to keep the indoor air clean and free from contaminants.
The fans can also be equipped with filters to remove particles and other contaminants from the incoming air. This ensures that the air that is circulated within the building is of high quality.
Benefits of using cell axial pressurization fans
There are several benefits to using cell axial pressurization fans in your building or enclosed space. One of the primary benefits is improved ventilation. By creating positive pressure within the building, the fans can help to circulate fresh air and remove stale air. This can help to prevent the buildup of pollutants and allergens, which can cause health problems.
Another benefit of using pressurization fans is that they can help to control the temperature of the building. By circulating fresh air, the fans can help to regulate the temperature and prevent hot or cold spots from developing.
Finally, pressurization fans can also help to reduce energy costs. By circulating fresh air, the fans can help to reduce the load on air conditioning systems and other climate control systems, leading to lower energy consumption and costs.
Types of cell axial pressurization fans
There are several types of cell axial pressurization fans available, each designed for different applications. Some of the most common types include:
Wall-mounted fans: These fans are mounted on the exterior walls of the building and are typically used to create positive pressure in smaller spaces.
Duct-mounted fans: These fans are mounted in the ductwork and are used to create positive pressure in larger spaces.
Roof-mounted fans: These fans are mounted on the roof of the building and are used to create positive pressure in larger spaces.
When selecting a pressurization fan, it is important to consider the size of the space, the amount of ventilation required, and the types of contaminants that may be present.
In conclusion, pressurization fans play a crucial role in creating a well-ventilated environment. By creating positive pressure within the building, the fans can help to circulate fresh air and remove contaminants, leading to improved air quality and a healthier environment. With different types available, it is important to select the right fan for your space and specific needs. By choosing the right fan, you can enjoy improved ventilation, temperature control, and energy savings
Whether you are managing an industrial facility, a farm, or a commercial building, cell axial pressurization fans are an important investment that can provide long-term benefits.
When installing pressurization fans, it is important to ensure that they are properly sized and installed for optimal performance. Professional installation is highly recommended, as a poorly installed or undersized fan can result in inefficient ventilation, increased energy costs, and even health and safety hazards.
In addition to proper installation, regular maintenance of the fans is important to ensure they continue to operate at peak performance. This may include replacing filters, cleaning the fans and ductwork, and inspecting the fan components for signs of wear or damage.
In summary, pressurization fans are a valuable tool for improving ventilation and maintaining indoor air quality in a wide range of applications. By understanding how they work, their benefits, and the different types available, you can make an informed decision when selecting and installing a fan in your building or enclosed space. With proper installation and maintenance, a pressurization fan can provide efficient and effective ventilation for many years to come.

La Palma giant lizard (Gallotia auaritae)
|Size||Snout-vent length: up to 44 cm (2)|
The La Palma giant lizard is classified as Critically Endangered (CR) on the IUCN Red List (1).
The La Palma giant lizard (Gallotia auaritae) belongs to the genus Gallotia, a distinctive group of lizards which occurs only on the Canary Islands (3). Although thought to be extinct, a possible sighting of this species in 2007 suggests that a remnant population of the La Palma giant lizard might still exist (1).
From the structure of its skeleton, the La Palma giant lizard is known to be a large, robust lizard with well developed, muscular legs (2). Male giant lizards are generally larger than females, with larger, sturdier heads (4). Although recent sighting of this species may be unconfirmed (5), it is described as being dark-brown in colour (2).
The La Palma giant lizard is endemic to the island of La Palma, in the Canary Islands. Its historic range is believed to extend from sea level, up to elevations of 800 metres (1).
While there is little information on the habitat preference of the La Palma giant lizard, it is believed to have previously inhabited the littoral zone throughout La Palma (1). It is thought to be absent from areas of pine and laurel (2).
An extremely rare and possibly extinct species, there is very little information on the biology of the La Palma giant lizard. The structure of its teeth suggests that this species is mainly herbivorous, and therefore feeds primarily on plant matter (2) (4). As with other members of the genus Gallotia, the La Palma giant lizard is thought to be a slow-growing reptile (2).
The La Palma giant lizard is believed to be an egg laying species (1).
The decline in the La Palma giant lizard population is believed to be mainly due to the arrival of humans to the Canary Islands (1) (2). As well as using this species as a source of food, humans also introduced other predators of the La Palma giant lizard, including cats and dogs (1) (2).
Loss of habitat due to land being converted for agriculture and competition with domestic stock have further threatened the survival of the La Palma giant lizard (1) (2).
The La Palma giant lizard is believed to be potentially extinct, with a sighting of this species in 2007 remaining unconfirmed (5) (6). If this species does still survive, the remaining population is likely to be extremely small, totalling less than 50 mature individuals. It is not known if this species occurs in any protected areas (1).
All giant lizards in the Canary Islands were believed to be extinct until the rediscovery of a number of species in the 20th Century (4). Urgent research is needed to establish whether a population of the La Palma giant lizard still exists, in which case recommended conservation measures include the establishing of strictly protected areas and preventing any future collection of this species for non-conservation purposes (1).

- Engineers can provide the government with advice on the research, information and funding needs.
- Engineers are central to the planning, design, construction and maintenance of infrastructure networks.
- Formal linkages between engineers, scientists and other key stakeholders would promote the sharing of up-to-date information.
The Government is seeking closer collaboration with the island's engineers as it seeks to develop sound implementation strategies for climate change adaptation and mitigation.
Minister of Water, Land, Environment and Climate Change, Hon. Robert Pickersgill,said engineers have a key role to play in assisting the country to adapt to climate change and the Government would welcome the technical expertise that they provide in this area.
"Engineers can provide the government with advice on the research, information and funding needs that (it) requires to safeguard our infrastructure and communities that are vulnerable to the effects of climate change," the Minister said.
He was addressing the opening of the Jamaica Institution of Engineer (JIE) three-day conference at the Knutsford Court hotel in Kingston on September 24.
The Minister noted that engineers are central to the planning, design, construction and maintenance of infrastructure networks which support economic activity and protect human health and welfare, and with climate change, major changes to the layout and use of these networks will therefore be required.
"This will ensure sufficient resilience to cope with foreseeable climate change impacts including an evaluation of the physical vulnerability of civil infrastructure such as road networks, water and sewerage systems and the energy grid," he said.
The Minister further noted that the creation of formal linkages between engineers, scientists and other key stakeholders which would promote the sharing of up-to-date information on best adaptive practices and regional climate datasets, could also provide input to government for setting research, legislative and expenditure priorities to support its climate change efforts.
"Regular and meaningful consultation between the engineering profession and the government on climate change policy is also required and I firmly believe that opportunities must be provided for professional engineers to acquire and upgrade their skills regarding new techniques and practices required to adapt to climate change," he said.
Minister Pickersgill further challenged engineers to seize the opportunities climate change presents to develop new, innovative infrastructure systems and services.
"Adaptation to climate change provides opportunities in the new green economy. New opportunities in engineering design and manufacturing will come from the development of low carbon renewable energy technologies including hydro, wind and solar; as will the building of resilience into existing infrastructure and designing new systems that are robust and efficient," he said.
Themed: 'Engineers Embracing Change', the event was held as part of activities to mark Engineers' Week which is being observed from September 22 to 29. Topics being discussed during the conference include the national building code; energy utilisation technology; climate change adaptation; construction and innovative design; manufacturing and industrial engineering; and risk management and disaster reduction.


that needs-based loco-regional health workforce planning can be achieved successfully through participatory processes with stakeholders. Stronger health systems and workforce training solutions were delivered by facilitating linkages and planning processes based on community need involving healthcare professionals across all disciplines and sectors. By focusing upon extending competencies and skills sets, local health professionals form a stable and sustainable local workforce. Concrete examples of initiatives generated from this process include developing a chronic disease inter-professional teaching clinic in a rural town and renal dialysis being delivered locally to an Aboriginal community. The growing trend of policy makers decentralising health funding, planning and accountability and rising health system costs increase the future utility of this approach. This type of planning can also assist the new PHNs to commission health services

 Creating a stable and sustainable health workforce in regional, rural and remote Australia has long been a challenge to health workforce planners, policy makers and researchers alike. Traditional health workforce planning is often reactive and assumes continuation of current patterns of healthcare utilisation. This demonstration project in Far North Queensland exemplifies how participatory regional health workforce planning processes can accurately model current and projected local workforce requirements. The recent establishment of Primary Health Networks (PHNs) with the intent to commission health services tailored to individual healthcare needs underlines the relevance of such an approach. This study used action research methodology informed by World Health Organization (WHO) systems thinking. Four cyclical stages of health workforce planning were followed: needs assessment; health service model redesign; skills-set assessment and workforce redesign; and development of a workforce and training plan. This study demonstrated that needs-based loco-regional health workforce planning can be achieved successfully through participatory processes with stakeholders. Stronger health systems and workforce training solutions were delivered by facilitating linkages and planning processes based on community need involving healthcare professionals across all disciplines and sectors. By focusing upon extending competencies and skills sets, local health professionals form a stable and sustainable local workforce. Concrete examples of initiatives generated from this process include developing a chronic disease inter-professional teaching clinic in a rural town and renal dialysis being delivered locally to an Aboriginal community.

 Prescribed fire is one of the most widely-used management tools for reducing fuel loads in managed forests. However the long-term effects of repeated prescribed fires on soil carbon (C) and nitrogen (N) pools are poorly understood. This study aimed to investigate how different fire frequency regimes influence C and N pools in the surface soils (0-10 cm). A prescribed fire field experiment in a wet sclerophyll forest established in 1972 in southeast Queensland was used in this study. The fire frequency regimes included long unburnt (NB), burnt every 2 years (2yrB) and burnt every 4 years (4yrB), with four replications. Compared with the NB treatment, the 2yrB treatment lowered soil total C by 44%, total N by 54%, HCl hydrolysable C and N by 48% and 59%, KMnO4 oxidizable C by 81%, microbial biomass C and N by 42% and 33%, cumulative CO2-C by 28%, NaOCl-non-oxidizable C and N by 41% and 51%, and charcoal-C by 17%, respectively. The 4yrB and NB treatments showed no significant differences for these soil C and N pools. All soil labile, biologically active and recalcitrant and total C and N pools were correlated positively with each other and with soil moisture content, but negatively correlated with soil pH. The C:N ratios of different C and N pools were greater in the burned treatments than in the NB treatments. This study has highlighted that the prescribed burning at four year interval is a more sustainable management practice for this subtropical forest ecosystem.

 The focus of this report is on North American wet deposition temporal patterns from 1979 to 1988 and spatial patterns for 1988. It is the third in a series of reports that investigate the patterns of annual precipitation-weighted average concentration and annual deposition for nine ion species: hydrogen, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. Mosaic maps, based on surface estimation using kriging, display concentration and deposition spatial patterns of pH, hydrogen, sulfate, nitrate, ammonium, and calcium ion species for 1988 annual, winter, and summer periods. Temporal pattern analyses use a subset of 35 sites over a 10-year (1979--1988) period and an expanded subset of 137 sites, with greater spatial coverage, over a 7-year (1982--1988) period. The 10-year period represents the longest period with wet deposition monitoring data available that has a sufficient number of sites with data of known quality to allow a descriptive summary of annual temporal patterns. Sen's median trend estimate and Kendall's seasonal tau (KST) test are calculated for each ion species concentration and deposition at each site in both subsets.

Retrieving Event Log Properties
Microsoft® Windows® 2000 Scripting Guide
Knowing the properties of your event logs can be useful in planning management activities such as backing up and clearing the logs. For example, knowing both the maximum allowable size and the current size of an event log tells you how much space is available in the log. In turn, this helps you decide whether the log needs to be backed up and cleared.
In addition, tracking the number of records in each log is a simple metric that can often trigger alarms regarding potential problems. For example, suppose routine checks of the number of records in an event log show that a specific computer typically records 100 events a day. Today, however, this routine check shows that the computer has recorded 500 events. This might indicate a serious problem that warrants further investigation.
The WMI class Win32_NTEventLogFile can be used to retrieve the properties of any event log on a computer. Some of the most important event log properties you can retrieve by using WMI are shown in Table 12.1.
Table 12.1 Event Log Properties Available Through WMI
Property
Description
FileSize
Current size of the event log, in bytes.
LogFileName
"Friendly" name for the event log (for example, System).
To return the actual path and file name of the event log (for example, C:\Windows\System32\Config\Sysevent.evt), use the Name property instead.
MaxfileSize
Maximum allowable size (in bytes) for the event log.
Although event logs can be sized as large as 4 gigabytes, in practice they should be limited to no more than 300 megabytes. Event logs larger than that can be difficult to analyze because of the number of events contained within the log and because event logs are not optimized for data retrieval.
Name
Full path and file name for the event log.
NumberOfRecords
Number of records in the event log.
OverwriteOutdated
Number of days after which a record can be overwritten should an event log reach its maximum size. Values are:
0 - Any record can be overwritten if necessary. If necessary, all existing events in the event log can be overwritten to make room for new events.
1-365 - Events older than the specified number of days can be overwritten as needed. If the event log does not contain any records older than the value specified, no new events will be recorded until the log has been cleared.
_PHONE_ - No records can be overwritten. If the log reaches its maximum size, no new events will be recorded until the log has been cleared.
OverwritePolicy
Current overwrite policy for the event log. Values are the following:
WhenNeeded - Any record can be overwritten to make room for new records.
OutDated - Records older than a specified number of days can be overwritten to make room for new records.
Never - Old records are never overwritten.

Scripting Steps
There are several ways to retrieve the properties of event logs. For example, you might want to:
 - Retrieve the properties of multiple event logs.
 - Retrieve the properties of a single event log.
 - Retrieve the properties of the Security event log.
Retrieving the properties of multiple event logs
Listing 12.1 contains a script that retrieves the properties of multiple event logs on a single computer. To carry out this task, the script must perform the following steps:
 1. Create a variable to specify the computer name.
 2. Use a GetObject call to connect to the WMI namespace root\cimv2, and set the impersonation level to "impersonate."
 3. Use the ExecQuery method to query the Win32_NTEventLogFile class.
 This returns a collection consisting of all the event logs on the computer, except the Security event log. The additional step required to return information from the Security event log is discussed later in this chapter.
 4. For each event log in the collection, echo the event log properties LogFileName, MaxFileSize, and OverWriteOutdated.
 If you configure an event log so that it never overwrites events, you actually set the OverWriteOutdated property to _PHONE_. If the value _PHONE_ is returned, the script displays the string "Overwrite Outdated Records: Never." If the value 0 is returned, this means the log has been configured to overwrite records as needed. To make this clear, the script displays the message "Overwrite Outdated Records: As Needed."

 Else
 Wscript.Echo "Overwrite Outdated Records After: " & _
 objLogfile.OverWriteOutdated & " days" & VbCrLf
 End If
Next
Retrieving a property of a single event log
Listing 12.2 contains a script that retrieves the number of records in the System event log. To carry out this task, the script must perform the following steps:
 1. Create a variable to specify the computer name.
 2. Use a GetObject call to connect to the WMI namespace root\cimv2, and set the impersonation level to "impersonate."
 3. Use the ExecQuery method to query the Win32_NTEventLogFile class.
 To limit the data returned to the System event log, include a Where clause specifying the LogFileName "System". This returns a collection of event logs with a single item: the System event log.
 4. For the only event log in the collection, echo the value of the NumberOfRecords property.

Set colLogFiles = objWMIService.ExecQuery _
 ("SELECT * FROM Win32_NTEventLogFile WHERE LogFileName='System'")
For Each objLogFile in colLogFiles
 Wscript.Echo objLogFile.NumberOfRecords
Next
Retrieving the properties of the Security event log
Scripts that retrieve information about the event logs on a computer do not retrieve information about the Security event log unless those scripts include the Security privilege. The ability to manipulate the Security event log is provided by the Manage auditing and security logs user right, which must be explicitly assigned. To manipulate the Security event log, you must include this privilege as part of the GetObject moniker, even if you are an administrator and have been assigned this right by default.
Note that the Security privilege does not grant you the ability to manage auditing and security logs. You must already possess this right (typically assigned through Group Policy), or the script will fail. To access information from or about the Security event log, you must possess the Manage auditing and security logs user right, and the script must include the Security privilege.
The results of querying event logs without including the Security privilege are shown inTable 12.2.
Table 12.2 Querying Event Logs Without Including the Security Privilege
If You Attempt to Access -
You Will Retrieve -
All the event logs on a computer

No special user rights are required to access any of the other event logs on a computer.
Listing 12.3 contains a script that retrieves the number of records in and the maximum file size of the Security event log. To carry out this task, the script must perform the following steps:
 1. Create a variable to specify the computer name.
 2. Use a GetObject call to connect to the WMI namespace root\cimv2, and set the impersonation level to "impersonate."

What is an OID?
Introduction to OIDs
An object identifier (OID) is an extensively used identification mechanism jointly developed by ITU-T and ISO/IEC for naming any type of object, concept or "thing" with a globally unambiguous name which requires a persistent name (long life-time). It is not intended to be used for transient naming. OIDs, once allocated, should not be re-used for a different object/thing.
It is based on a hierarchical name structure based on the "OID tree". This naming structure uses a sequence of names, of which the first name identifies a top-level "node" in the OID tree, and the next provides further identification of arcs leading to sub-nodes beneath the top-level, and so on to any depth.
A critical feature of this identification mechanism is that it makes OIDs available to a great many organizations and specifications for their own use (including countries, ITU-T Recommendations, ISO and IEC International Standards, specifications from national, regional or international organizations, etc.).

How are OIDs allocated and what is a registration authority?
OID registration standards
At each node, including the root, there is a requirement for some organization or standard to be responsible for allocating arcs to sub-nodes and recording that allocation (together with the organization the subordinate node has been allocated to), not necessarily publicly. This activity is called a Registration Authority (RA).
In the OID tree, RAs are generally responsible only for allocation of sub-arcs to other RAs that then control their own sub-nodes. In general, the RA for a sub-node operates independently in allocating further sub-arcs to other organizations, but can be constrained by rules imposed by its superior, should the superior so wish.
The registration tree is indeed managed in a completely decentralized way (a node gives full power to its children).
The registration tree is defined and managed following the ITU-T X.660 & X.670 Recommendation series (or the ISO/IEC 9834 series of International Standards).

What is an OID repository?
Features offered by this OID repository
Initially, it was left for each Registration Authority (RA)in the hierarchy to maintain its own record of allocation beneath that RA, and to keep those allocations private if it so chose. There was never any policing of this. An RA in the hierarchy was its own master and operated autonomously.
In the early 1990s Orange developed software for their internal use which was generic enough to provide a publicly available repository of OID allocations.
Information on OIDs is often buried inside the databases (perhaps sometimes paper) maintained by an immense number of RAs. The information can be hard to access and is sometimes private. Today this OID repository is regarded as the easiest way to access a large amount of the publicly available information on OIDs: Many OIDs are recorded but it does not contain all existing OIDs.
This OID repository is not an official Registration Authority, so any OID described on this web site has to be officially allocated by the RA of its parent OID. The accuracy and completeness of this OID repository rely on crowdsourcing, i.e., each user is welcome to contribute data.

Knowledge Base
KB10327 - Explanation of In-Memory and On-Disk vector layers.
To manipulate an object, you first must access it from a layer. With the TatukGIS DK, a vector layer can be either in-memory or on-disk.
 - In-Memory layer
 This means that the whole layer (all shapes) is kept in the RAM. In this situation, every shape has its own private address which is persistent during the session.
 - On-Disk layer
 This means that the whole layer (all shapes) is kept on the disk. In this situation, the shapes are active only for a while. The shape is active only within the scope of a single procedure. The benefit of storing layers on-disk in this manor is quite simple. Every read from disk operation will read into the memory only a single shape. Thanks to this, the DK can efficiently handle very, very large files. (This is a key advantage of the DK over other GIS toolkit products.)
With some vector layer file types (DXF, MIF, TIGER), the DK always loads the layers into memory because random access to the shapes on disk in these formats is not possible. But several other vector layer formats (SHP, DGN TAB, SQL) allow random access to the shapes which always reside on disk. With these file types, selected shapes from the layer exist in-memory only if marked using the MakeEditable method (explained more below).
What does this mean to the DK developer? It means that, unless you are 100% sure that a layer is in-memory, never make any assumptions about the shape pointer, parameters, etc.
For example, do not expect code such as the following to work properly:
 shp.Params.Area.Color := clRed
This command can work for a while – until the next shape is fetched from a disk file to in-memory status. When this happens, changes to the prior shape are lost from memory.
To address this issue, the DK provides the MakeEditable method to maintain hybrid layers. A hybrid layer is a layer which is part disk based, but in which selected shapes are kept in-memory. This provides a perfect solution for editing because only the edited shapes are kept in memory and are joined with the disk based file upon save.
To move your shape into the memory, just call
 myshp := shp.MakeEditable
It is very important to use a newly assigned myshp variable for any subsequent calls. Calling
 shp.MakeEditable
informs the software that the shape is in-memory, but still keeps the old pointer referenced to the disk based file.
Calling MakeEditable is safe. It can be called as many times as wanted without side effects. We recommend that you use it before any "editing" function. For Example:
 shp := layer.GetShape(12) ;
 If Assigned( shp ) then begin
 shp := shp.MakeEditable ; // be sure that it is editable object
 shp.Params.Area.Color := clRed
 end
An object may be reverted to disk-based status by simply calling layer.Revert( shp.Uid ). This will delete a shape from the in-memory list. But keep in mind that, if used on an in-memory based layer or for a newly created object, the whole shape can be lost.
Comments:
 - Every object created by layer.CreateShape is in-memory.
 - To check if an object is in-memory, call the shp.IsEditable function. But do not do this unless it is really important because the result is obtained by searching the in-memory list, which can slow down the computation.

|Numerical analyses and experiment investigations of an annular micro gas turbine power system using fuels with low heating values
Department of Mechanical Engineering
|numerical analyses;experiment investigations;annular micro gas turbine;low heating values
|This study investigates the effects of using fuels with low heating values on the performance of an annular micro gas turbine (MGT) experimentally and numerically. The MGT used in this study is MW-54, whose original fuel is liquid (Jet A1). Its fuel supply system is re-designed to use biogas fuel with low heating value (LHV). The purpose is to reduce the size of a biogas distributed power supply system and to enhance its popularization. This study assesses the practicability of using fuels with LHVs by using various mixing ratios of methane (CH(4)) and carbon dioxide (CO(2)). Prior to experiments, the corresponding simulations, aided by the commercial code CFD-ACE+, were carried out to investigate the cooling effect in a perforated combustion chamber and combustion behavior in an annular MGT when LHV gas was used. The main purposes are to confirm that there are no hot spots occurring in the liners and the exhaust temperatures of combustor are lower than 700 degrees C when MGT is operated under different conditions. In experiments, fuel pressure and mass flow rate, turbine rotational speed, generator power output, and temperature distribution were measured to analyze MGT performance. Experimental results indicate that the presented MGT system operates successfully under each tested condition when the minimum heating value of the simulated fuel is approximately 50% of pure methane. The power output is around 170 W at 85000 r/min as 90% CH(4) with 10% CO(2) is used and 70 W at 60000 r/min as 70% CH(4) with 30% CO(2) is used. When a critical limit of 60% CH(4) is used, the power output is extremely low. Furthermore, the best theoretical Brayton cycle efficiency for such MGT is calculated as 23% according to the experimental data while LHV fuel is used. Finally, the numerical results and experiment results reveal that MGT performance can be improved further and the possible solutions for performance improvement are suggested for the future studies.

Hey guys, I'm trying to write custom built in solidworks tutorials, and one function the current ones use is a function called FlashIt, where you click a button in the tutorial screen and it flashes up on the solidworks screen to show you where it is. However, this function needs the variable input "ButtonID", which seems to be just a random typed in number from what I can see.
Is there some list somewhere of what button has what button ID? Or is there some way to find out?

Gulf Oil Spill 2010: Light Crude Oil and Your Health
What is light crude oil?
Light crude oil is a mix of thousands of different chemicals, but it is mostly hydrogen and carbon. It comes out of the ground as liquid petroleum.
How does light crude oil spread?
When oil is spilled in the ocean, it spreads in the water, mostly on the surface. The oil slick formed may stay together, or it may break up in rough seas. Waves, currents, and wind spread the oil over large areas. A small part of the oil may dissolve in the water. The oil also can spread in the water, join with the water to form a thick substance that is like hair mousse, sink, or form into sticky tar balls.
What are the health threats of light crude oil?
For most people brief contact with a small amount of oil will do no harm. Some people are more sensitive to chemicals, including those found in crude oil. These people may develop a rash or skin irritation or have other allergic reactions.
Skin contact with crude oil that lasts a long time can cause skin reddening, swelling, and burning. The skin effects can get worse if the skin is exposed to the sun. Skin contact can also make you more likely to develop a rash or skin infection.
Light crude oil may also be irritating if it contacts your eyes.
Swallowing small amounts (less than a coffee cup) of oil will cause upset stomach, vomiting, and diarrhea, but is unlikely to have long-lasting health effects.
How can I avoid the health threats of light crude oil?
Avoid skin contact with oil. If you are involved in clean-up efforts, wear gloves, eye protection, and clothing that cover your arms and legs.
If you get oil on your skin, wash with soap and water, baby oil, petroleum jelly, or a cleaning paste for hands such as those sold at auto parts stores. Do not use solvents, gasoline, kerosene, diesel fuel, or similar products to clean oil off skin.
If you get oil in your eyes, flush them with water for 15 minutes.
If you swallow oil, do not try to vomit it, as this may get oil into your lungs.
If you inhale oil vapors, or smoke from burning oil, move to an area where the air is more clear. If you have inhaled a lot of vapor or smoke and feel short of breath, have chest pain or tightness, or dizziness, seek medical attention.

Control system of pure uv water purifier what characteristics? Small make up today from three aspects to give you a brief introduction to the main characteristics of pure water equipment, to deepen your understanding of pure water equipment control system. If you have other problems of pure water equipment is convenient, welcome consulting staff. 1, the main control loop water net equipment imports of high-pressure pump with low voltage protection switch, export is equipped with high voltage protection switch. High pressure pump and water tank low level interlock. When the high pressure pump imported low voltage switch action, the system will automatically sends a signal to stop the high pressure pump continues to run, protect the high pressure pump in the water under the condition of steady work. When the error due to other reasons, the high-pressure pump outlet pressure exceeds a certain value, high pressure pump discharge pressure protection can cut off the high pressure pump power supply function, protection system is not running under ultra-high pressure environment. Step 2, the main control object and control sequence of pure uv water purifier control mode is a state transition model based on time sequence, state transition is not bouncing, PC monitor screen system to start and stop of two buttons, triggers the start button, the state began to transform, the vast majority of transformation are regularly occur, only under the running condition, transformation can be triggered by press the stop button. 3, pure water equipment application state of motion output sequence formed after it will be very helpful to determine the output of the device action, it can make the programming more facilitation., for example, to determine the output of the inlet valve can read the inlet valve control step sequence table columns, shows that inlet valve is in three periods is open, the rest of the state is closed, and after two periods is continuous.
