Brno - Klein Palace
This neo-Renaissance burgher palace was built in _PHONE_ on a design by Viennese architect Ludwig von Förster. It was built for the Klein family who traded in iron. This was also reflected onto the house, respectively into its facade, which was fitted with distinctive architectural elements of cast iron.
In 1946, the palace was confiscated and began to deteriorate, mainly due to insufficient maintenance and the confused and inadequate use of its premises for various purposes. The years _PHONE_ saw a costly reconstruction (to the tune of about 70 million CZK) and the house was brought back to life.

Food for Fort: On soya cream and Freedom Food
Can I use soya cream instead of double cream in a quiche? Plus what, exactly, is Freedom Food?
Can you really make a decent quiche without using double cream? Photograph: Colin Campbell for the Guardian
I made my first quiche the other night. Next time, can I substitute soya cream or something similar for the double cream in most recipes? I know it sounds awful, but I want to have my quiche and eat it, too.
It's not something I'd do myself, but having consulted several authorities on the subject, there's no reason you can't substitute soya cream for double cream (or a mixture of tofu and soya cream, to produce the fluffy effect you get from cream). It won't have the same taste or texture of a classic quiche but, yes, you can have your quiche and eat it.
What, exactly, is Freedom Food? It's an increasingly popular label, yet seems to be shy of being free-range.
Freedom Food is a scheme introduced by the RSPCA in 1994. The five basic criteria are: freedom from hunger and thirst; freedom from discomfort; freedom from pain, injury or disease; freedom to express normal behaviour; freedom from fear and distress. It is designed to ensure that animals reared for food are treated to specified welfare standards. Free-range and organic practices are not part of the criteria. For some animal rights organisations, those standards do not go far enough; others say they tacitly endorse meat consumption. There have been criticisms, too, that the scheme has cost implications for the foods labelled, and that there may be a gap between the rules and their enforcement. On the other hand, you could say that it shines like a beacon in a world fed through dubious farming practices.

text: A novel signaling scheme for iterative channel estimation and data decoding is proposed. In the proposed scheme, the occurrence probability of transmitted symbols is biased. A priori information about the bias is utilized for the initial channel estimation. The proposed scheme is based on parallel concatenation of two biased convolutional codes (BCCs), which are constructed as systematic recursive convolutional codes with state-dependent puncturing. The BCCs can be regarded as a joint coding scheme that determines the insertion positions of pilot symbols according to information bits. The proposed scheme is numerically shown to outperform conventional pilot-based schemes in the waterfall region, while it is inferior to the conventional schemes in the error-floor region.


When creating or editing a form, how can you copy multiple items/sections?
I am a developer for Cognito Forms.
First, if you are trying to capture the same information multiple times, you can use a Repeating Section, which is a section that the user filling out the form can repeat as necessary to enter the same information for a list of items, like players on a baseball team, employment history, medical conditions, etc.
Example of Repeating Sections
Second, while you can only copy one thing at a time, you can place a number of items (including both fields and other sections) into a section, and then copy and paste the entire section and all of the items contained in the section will be copied as well.

Job Demands-Resources Theory and Experience Sampling
24 June 2019
Begin time:
CITEC 1.204
JD-R theory is a theory about the causes of employee well-being and behaviors that can be used to predict a wide range of organizational outcomes.
Accordingly, employees are confronted with and proactively modify various job demands and resources, which consequently impact job strain and work engagement, and have an indirect effect on creativity, performance, etc.
In this presentation, I will discuss the basic propositions of JD-R theory, and discuss the available evidence.
The focus will particularly be on daily diary and experience sampling studies, to illustrate how mobile devices and technology can be used to study employees during work, while they are confronted with various external demands and resources.
Everyone is invited to join the talk.

or muffin Case
Step by step
Learn how to create a muffin/cupcake case with your Trotec laser machine. Made from our incredibly popular TroLase Thins material, these festive cases will add the perfect finishing touch to your Christmas sweets.
Step by step
Step 1: Design
You can use the template we have provided, or alternatively, you can create your own unique design. The parcels are defined as engraving areas by the black fill. Snow crystals and border lines must be defined as cutting lines (width: hairline; R: 255; G: 0 B: 0). To add a personal touch, simply insert text at the bottom of the graphic.
Step 2: Bend graphic
In order to bend the strip to a muffin case, you need to bend the graphics in Adobe Illustrator using the warping tool. If you are using Corel Draw you need to use the tool 'Envelope' (Menu: Effects > Envelope > Simple arc > Putty). Hold Ctrl and then drag the lines to the desired arc.
Step 3: Settings
Cutting: power: 300% - speed: 1.5% - frequency: 1000 Hzair assist: ON
Engraving: power: 70% - speed: 80% - frequency: 500 ppi - air assist: ON - Z-Offset: 1mm - high quality: ON
In the menu plate setup, select start position bottom. Remove the protection foil from the laminate and check the vacuum. Focus the laser and you are ready to go!
Step 4: Tips & Tricks
- Ensure that you consider the cutting sequence - In the product process the cutting lines are considered bottom up. Place the outline at the top position in Corel Draw Object Manager
- Cover unused parts of the table with paper in order to increase your vacuum.
- Select the engraving start position as 'bottom'. This prevents deposits from setting on engraved areas which could discolour the product.
- First clean with a damp cloth then dry, preferably whilst it is still in the machine.
- If colour residues are present it is important to check the parameters, focus and check the rest of the laminate on the table.

UFT/QTP virtual memory issues
Have you ever encountered virtual memory issues when running long QuickTest Professional or Unified Functional testing scripts? They tend to occur while running either long overnight tests, or tests that have a ton of iterations. (If you're a sadist, your scripts might do both.)
Here are three things that might be causing your virtual memory issue:
- Not defining all your functions in a global function library
- Your application is not releasing memory
- QTP/UFT is not releasing memory
Place all your functions in a global function library
A leading cause of virtual memory issues is when local variables and functions are used within Actions. When this approach is used, QuickTest does not release its memory until it closes.
For example, if you have an action that iterates 1,000 times and you've defined 10 local variables, after 1,000 iterations enough memory will have been allocated for 10,000 variables! Things get even crazier if you're using an action-based framework that involves multiple actions calling each other.
The medication to relieve some of these memory allocation symptoms is to move all your variables and functions into a QTP VBScript library. Creating a function library won't solve all your memory usage issues, but it will help drastically minimize your memory usage.
Under QTP's File>settings>Resources section, you can point to your function library using the add button to associate your function library with the test script.
Once your script has a reference to the function library, you'll be able to call all the functions by typing them directly into your script. By creating a library file, you make your functions accessible to all your UFT scripts. Not only will this alleviate virtual memory issues, but it also will help:
- Simplify code for easier readability and maintenance
- Allow you to override an existing object method
- Abstracts your code for use and reuse in scripts, business components and recovery scenarios
If you don't know how to create a function library, take a look at the following example.
Creating a Library File
To create a function library you can either select File>New>Function Library in QuickTest Professional, or create a new file in a text editor like Notepad. For example:
- Create a new file in Notepad.
- Enter the following:
Function testMsg(firstName, lastName) msg = "Hello " & lastName &"," & firstName msgbox msg End Function
- Save as myFunction.txt to your C drive.
- In UFT/QTP, select File>New test.
- In the new test, click on File>Settings>Resources click on the add (+) button.
- If you get a "Relative Path" dialog, click No.
- The myFunction.txt library should now show up under the Resources section. Click on the "Test Settings" apply button.
- In your test, under the expert view, begin typing in the function name testMsg. Notice how the parameters for the function are shown.
- Enter the name:
- Click Run.
Your application is not releasing memory
There's no real solution for this if you're testing an application that's a memory hog. But in general, you might be able to free up some memory by minimizing the application. If minimizing doesn't help you should try starting and stopping your application for each test, or create a script that stops and restarts your application after a few tests have run. This is an issue I've commonly encountered when testing against IE, and I've found that minimizing the browser tends to solve things much of the time.
QTP/UFT is not releasing memory
Let's be honest. QTP/UFT itself can be a huge memory drain on your tests. If you're running tests that take hours and have lots of iterations you're inevitable going to encounter some issues. My advice is to restart QTP/Unified Functional Testing during replay, which will help to free up any memory that QuickTest Pro is holding onto. To do this you can use QTP's Automation Object Model. HP's knowledge base has a pretty cool code example on how to use AOM, as well as environment variables to help determine when to restart QTP after number of iterations:
(Source: The rest of this post is taken directly from HP's KB Site) The following set of instructions is a proposal with a on to generic approach to handle scenarios where QTP needs to be restarted:
1. Create a.vbs file (using AOM statements) that can be called from within QuickTest Professional. The.vbs file should check:
If QuickTest Professional is running, modify a couple environment variables (these will control the iterations) and shut down QuickTest Professional.
If QuickTest Professional is not running, launch it. Set some run-time settings, and start the script execution.
Example contents of the.vbs file:
' Wait 2 seconds to allow QuickTest Professional to complete replay overhead. wscript.sleep 2000 'Create a QuickTest Professional AOM object Set qtApp = CreateObject("QuickTest.Application")'Check to see if QuickTest Professional is open (not necessarily running a script) if qtApp.GetStatus <> "Not launched" then set qtTest = qtApp.Test'Get access to the test'Get the current value of the "it_start" environment variable. This is the iteration start index. itstart = qtTest.Environment.Value("it_start")'Get the current value of the "it_stop" environment variable. This is the iteration stop index. itstop = qtTest.Environment.Value("it_stop")'Set the new values of the it_start and it_stop variables qtTest.Environment.Value("it_start") = CInt(itstop) + 1 drows = qtTest.DataTable.GetRowCount if drows > CInt(itstop) + 4 then stp = CInt(itstop) + 4 else stp = drows end if qtTest.Environment.Value("it_stop") = stp'Close QuickTest Professional qtApp.Quit end if'Wait 2 seconds to allow QuickTest Professional processes to end wscript.sleep 2000'Launch QuickTest Professional and make it visible qtApp.Launch qtApp.Visible = True'Open the test script. Update to have full path to your test script qtApp.Open'Get the current value of the "it_start" environment variable itstart = qtApp.Test.Environment.Value("it_start")'Get the current value of the "it_stop" environment variable itstop = qtApp.Test.Environment.Value("it_stop")'Set the Test Iterations for the script qtApp.Test.Settings.Run.IterationMode = "rngIterations" qtApp.Test.Settings.Run.StartIteration = itstart qtApp.Test.Settings.Run.EndIteration = itstop'Run the test qtApp.Test.Run'Release the QuickTest Professional object Set qtApp = Nothing
Note: Update the.vbs file to specify the full path to the test you wish to restart.
2. Open your test script, and go to Test -> Settings.
3. In the Environment tab, select "User-defined" in the Variable type field.
4. Enter two new variables, it_start and it_stop. (You can use other names, if you wish, but you will need to change the vbs file also.)
5. Set the it_start value to 1. Set the it_stop value to the number of iterations you want to complete before restarting QuickTest Professional (for example, 1000).
6. At the end of the script (or in the last action), add code that will call the.vbs file when appropriate.
If Environment("TestIteration") = 1000 Then'1000 iterations complete. Restart QuickTest Professional SystemUtil.Run "closeQTP.vbs" End If
In the above example code, the Test Iteration Environment variable is retrieved and checked to see if it has reached the limit set in step 5 (1000 iterations in the example). If the iteration limit has been reached, the.vbs file is launched. The start and stop iterations will be captured and stored and QuickTest Professional is restarted (if needed).
Make sure you update the.vbs file reflect the iteration limit you set in your script.
You should be able to start your script now and it will shut down and restart QuickTest Professional after x iterations.
Each time QuickTest Professional re-launches and starts to replay the script, a new test results folder will be created. Using AOM you can have some control over the test results folders, but you should not use the same folder for each launch of the script if you need to save the test results (QuickTest Professional will overwrite the previous results, not append to them).
Some QuickTest Professional test environments, such as Web, require the application to be started after QuickTest Professional. Keep this in mind and structure your test as needed to allow you to restart the application if required.
You should use the VBS file to launch the test script.

SHRM Assurance of Learning
Assurance of Learning Assessment for Graduating HR Students:
The Society for Human Resource Management's (SHRM) Assurance of Learning Assessment for graduating HR students is the new universal benchmark for students who are completing an HR degree and who have little to no work experience in HR. It benefits students by showing employers the student has acquired the minimum knowledge required to be a successful HR professional, and it gives recent graduates an important advantage over other entry-level candidates by showing the student has achieved the Certificate of Learning upon passing an exit exam. The assessment helps universities meet their accrediting body's assurance of learning requirements because it helps show the HR degree program teaches what it states it will teach. And, it helps employers know that the student has taken an additional step to ensure their degree, complemented by the Certificate of Learning achievement, adequately prepares them for their career in HR. As part of SHRM's broader academic initiative, the Assessment represents an important step along an HR professional's career development path. It complements both formal classroom knowledge acquired through a degree program and experiential learning gained through internships. To learn more, visit the Assurance of Learning page on the SHRM website.

Dyson Digital Motor
Michael Faraday invented the first electric motor in 1831 and its design has remained largely unchanged ever since. Lots of moving parts and a big, fragile fan make them unreliable. And they release carbon particles as their brushes wear down.
Dyson engineers spent seven years developing a new type of motor. Half the size and weight, the Dyson digital motor spins 88,000 times a minute - five times faster than a Formula One car engine. Fewer moving parts also means it lasts four-times longer than ordinary motors.
So far, it's being used in all our cordless machines as well as the Dyson Airblade™ hand dryer.

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.

A dispersal vector is an agent of biological dispersal that moves a dispersal unit, or organism, away from its birth population to another location or population in which the individual will reproduce. These dispersal units can range from pollen to seeds to fungi to entire organisms.There are two types of dispersal vector, those that are active and those that are passive. Active dispersal involves pollen, seeds and fungal spores that are capable of movement under their own energy. Passive dispersal involves those that rely on the kinetic energy of the environment to move. In plantts, some dispersal units have tissue that assists with dispersal and are called diaspores. Some types of dispersal are self-driven (autochory), such as using gravity (barochory), and does not rely on external agents. Other types of dispersal are due to external agents, which can be other organisms, such as animals (zoochory), or non-living vectors, such as the wind (anemochory) or water (hydrochory).

A react-spring driven masonry-like grid with enter/exit and shared element transitions.
How to use
import { Grid } from'mauerwerk'
 // Arbitrary data, should contain keys, possibly heights, etc.
 // Key accessor, instructs grid on how to fetch individual keys from the data set
 keys={d => d.key}
 // Can be a fixed value or an individual data accessor (for variable heights)
 // If you leave it undefined it will assume 100% container height
 heights={d => d.height}
 // Optional: number of columns (make it responsive yourself using react-measure/react-media)
 // Optional: space between elements
 // Optional: removes the possibility to scroll away from a maximized element
 // Optional: delay before minimizing an opened element
 // Optional: animates the grid in if true (default)
 {(data, open, toggle) => (
 {open && Opened/maximized content here}
 {open? 'Close' : 'Open'}
You feed mauerwerk any data-set (an array of objects most likely), give it accessors so it can access keys (which can be names, hashes, etc., the same keys you'd normally hand over to React), and either a fixed cell height or individual heights. You render out each individual cell via render-prop. You'll receive three arguments:
 1. data, the item from your data-set
 2. open, the cells state, depending on whether it is true or false you can display varying content or use further animation prototypes to transition from cell-state to maximized-state
 3. toggle, use this to maximize/minimize your cell
You probably don't want flip between open/closed content using static conditions. mauerwerk comes with two simple to use effects:
 - Fade will fade contents in according to the show property. It's a simgple wrapper around react-spring's Transition, you can feed it the same properties (config, from, enter, leave, update). By default it will just move opacity from 0 -> 1.
 - Slug lets elements "crawl" in. It's a wrapper around react-spring's Trail. By default it will move opacity from 0 -> 1 and translate y from 40px -> 0px.
These two would work outside the Grids context if you wanted to use them elsewhere.
import { Grid, Slug, Fade } from'mauerwerk'
 {(data, open, toggle) => (

 Some text

Artificial intelligence is growing widely and developing to a large extent. In Africa, universities are creating and empowering in the educational sector. Ai should be highly recommended and introduced in all universities in Africa, the government should focus more on working for the development of Ai because it can render good services to teachers via search and can help concentrate more on educating students.
The migration of pre-colonial Africans depends on seasons for the purpose of fertile soil, the cause of this made education not to be fully organised in pre-colonial Africa. They were dependant on learning their own tribe, values, socialization and responsibilities.
Image result for 6 Reason Why AI Should Be Introduced In University In Africa
Since 1960s there have been different artificial technologies in sub-Saharan African. Artificial intelligence is growing widely and developing to a large extent. In Africa, universities are creating and empowering in the educational sector.
The reasons AI should be introduced more in Africa universities follow.
1.Enhance research in education; there is a need to grow talent. Application of Ai can help students understand more about technology. Its aim is to create real-world intelligent system s where leading scientist and engineers are practised and knowledge is carried out.
This process can help understand more about technology. School of chemistry deployed new Ai research initiative for Africa ( wits university Johannesburg, south Africa) in association with cirrus. Google also opened its first lab in Ghana
2. Improve Student Learning Ability: people learn and understand in different ways, some likely learn fast. The introduction of artificial intelligence in schools can help instructions focus more on understanding the weakness and strength of a student. The Watson tutor (IBM) this technology is a platform that involves machine learning with the use of natural language. A mode of learning through artificial intelligence in the educational sector
3. Acquiring all round skills: Ai can help students acquire new skills. Application of artificial intelligence can not only help student focus on just one still it also enable students to live their full potential through social entrepreneurship and digital innovation. Some students have good potential. All services can render technological skills in Africa universities. This is one inspiring way to create a better world for Africa.
4. Make Teaching Fun: this can motivate the ability to learn fast and manage mental wellbeing. For example, with the use of Chatbot to perform task. Chatbot is an easy way of learning that interacts with students. Students are now offered a quick way it gets valuable information's. This has made learning fun and less stressful
5. Enhance Students Experience: Ai increases learning opportunity. The Stanford University report explains how Ai will help in the educational sector a few years from now by using data analytics to address issues facing universities, figuring out students who are at risk of failure or dropping out. It also stated that ai is promising to improve education in all level
6. Prepare Instructors For A Higher Educational Teaching : Ai tool that can assist instructors to teach students. Ai has introduced many interesting way of education all around the globe.
This is just its beginning of innovation. The aim is not to take over humans, but rather to assist and make the world a better place. Subjectively, I'd plead to the administrators around African to enhance the use of Ai in all universities in Africa
Lastly, students should learn more about algorithms and the use of Ai in decision making. Doing this will not only benefit a student but will also assist Africa to become a better place if Ai is fully deployed in the educational sector

Abstract: We study the contribution of multiple covers of an irreducible rational curve C in a Calabi-Yau threefold Y to the genus 0 Gromov-Witten invariants in the following cases. (1) If the curve C has one node and satisfies a certain genericity condition, we prove that the contribution of multiple covers of degree d is given by the sum of all 1/n^3 where n divides d. (2) For a smoothly embedded contractable curve C in Y we define schemes C_i for i=1,...,l where C_i is supported on C and has multiplicity i, the integer l (0l). In the latter case we also get a formula for arbitrary genus. These results show that the curve C contributes an integer amount to the so-called instanton numbers that are defined recursively in terms of the Gromov-Witten invariants and are conjectured to be integers.


Kary Bosma on Jubilee Fellows' Summer Internships
Kary Bosma coordinates Jubilee Fellows, a Calvin College summer internship for students considering pastoral ministry.
Kary Bosma coordinates Jubilee Fellows, a Calvin College summer internship for students considering pastoral ministry. Each summer Bosma and Jubilee Fellows co-directors Dale Cooper and Todd Cioffi divide visits among 12 interns.
Kary Bosma
Will you describe a typical visit?
We try to visit during weeks four or five of their ten-week internships, so we need to coordinate timing along with geography. A program representative visits an internship site for one or two days, enough time to discuss everything, including living with their host family and daily routines. We talk most about their internship. They make goals with their supervisor when the internship begins and complete a mid-point report to evaluate how well they are accomplishing their goals. We discuss how their work so far has impacted his or her sense of calling to ministry.
What challenges do Jubilee Fellows experience?
We talk about how the student is maintaining her relationship with God in the midst of serving him. We discuss what has surprised them about working in ministry. We also talk candidly about any difficulties, whether personal struggles or in work or with their supervisor or host family.
We meet with the student's mentor and any other church staff working closely with the student. It's an opportunity for them to speak honestly about the student's performance and express concerns. We express our gratitude for their mentoring our student.
How do these summer internships affect Jubilee Fellows?
Most come away with a new understanding of and appreciation for the daily work of church ministry. Students are often given opportunities to work in their interest areas, such as teaching, youth, and worship. They're challenged to participate in areas they aren't aware of or don't feel particularly gifted in, such as administration, children, and pastoral care. They often express surprise at all the behind-the-scenes work that happens daily or weekly. They find that, besides preaching on Sunday, a pastor may lead a funeral, make pastoral care visits, attend a worship planning meeting, fold bulletins, and manage church finances. A church educator planning for vacation Bible school must choose curriculum, plan activities and crafts, market the program to members and the community, recruit and coordinate volunteers, purchase snacks, and decorate the church basement.
Often students approach the summer hoping for affirmation about what career path to follow. Sometimes they expect to find the final answer to "Might God be calling me to a vocation in church ministry?" What often actually happens is they spend the summer learning more about themselves: how God has equipped them, which ministry areas best use their gifts, and how to improve in areas of weakness. Mentors reflect weekly with students on how their experiences are effecting or affecting their calling. Mentors affirm their gifts and challenge them when appropriate.
Why do churches continue or stop hosting Jubilee Fellows?
Congregations and mentors are often eager to welcome future Jubilee Fellows after their initial experience. They are usually pleased with the work done and student quality. It is a unique opportunity for churches to gain a highly motivated, thoughtful intern as part of a well-organized and established program...at no financial cost to the church. Several congregations host students year after year, because their staff and congregations are committed to mentoring future church leaders. Mentoring takes significant time and energy for the mentoring pastor, church staff, host family, and congregation. Not all churches are able to sustain an intern every year. Pastoral sabbaticals, retirements, or changing leadership may prevent churches from hosting another Jubilee Fellow.
Churches often want to host a Jubilee Fellow, but I don't have enough students to send out! As our network of internship churches expands—this year eight of our students are at new internship sites— we are blessed with the task of connecting each student with the church that best suits their vocational interests. I work with pastors at each potential site to determine the best fit. We prayerfully determine which churches will receive a Jubilee Fellow and which will have to wait.
As you look back on the years of Jubilee Fellows, how many have gone on to seminary or a church-related job?
Around 75 percent of former Jubilee Fellows have gone on to seminary or to serve in ministry-related fields, such as unordained church ministry, parachurch organizations, and missions.
The Jubilee Fellows program is part of Calvin College's Congregational and Ministry Studies (CMS) department. Read about CMS throughstudents ' eyes.

Tackling Cancer Pain – A toolkit for patients and families was Highly Commended at the British Medical Association (BMA) Patient information awards 2016.
The reviewer said 'This resource is of an exceptionally high standard; the amount of effort that went into producing and reviewing it is clear. It's very well-presented, and contains a large amount of helpful information in a clear and easy to read way. This really is an excellent resource.'
The purpose of Tackling Cancer Pain is to provide evidence-based information and practical advice for patients and families about self-management of advanced cancer pain. The resource comprises a booklet in the form of a compact loose-leaf A5 ring binder with a DVD attached to the inside front cover. Both were designed on the basis of an extensive literature review and user involvement and produced with the input of professional film-makers and designers. The booklet and DVD contain essentially the same information but in different formats and are structured so that they can be used independently by patients or family members. They can also form the basis for one-to-one or group education or coaching from a health professional. Clear guidance is given in each chapter about how to use the information presented. Step-by-step tuition is provided on non-pharmacological pain relief measures such as relaxation and visualisation, and on how to initiate and conduct conversations about pain with health professionals.

optional and defaults the default destination.
Tool collections contain zero or more s, which map to parameters set at job-creation, to allow for assignment of handlers and destinations based on the manner in which the job was created. Currently, only one parameter is defined - namely source.
The content of the tag is the component that created the job. Currently, only Galaxy's visualization component sets this job parameter, and its value is trackster.
trackster
Dynamic Destination Mapping
Galaxy has very sophisticated job configuration options that allow different tools to be submitted to queuing systems with various parameters and in most cases this is sufficient. However, sometimes it is necessary to have job execution parameters be determined at runtime based on factors such as the job inputs, user submitting the job, cluster status, etc… In these cases the dynamic job destination mechanism allows the deployer to describe how the job should be executed using python functions. There are various flavors of dynamic destinations to handle these scenarios.
The two most generic and useful dynamic destination types are python and dtd. The python type allows arbitrary Python functions to define destinations for jobs, while the DTD method (introduced in Galaxy 16.07) defines rules for routing in a YAML file.
Dynamic Destination Mapping (DTD method)
DTD is a special dynamic job destination type that builds up rules given a YAML-based DSL - see config/tool_destinations.yml.sample (on Github) for a syntax description, examples, and a description of how to validate and debug this file.
To define and use rules, copy this sample file to config/tool_destinations.yml and add your rules. Anything routed with a dynamic runner of type dtd will then use this file (such as the destination defined with the following XML block in job_conf.xml).

 dtd
Dynamic Destination Mapping (Python method)
The simplest way to get started with dynamic job destinations is to first create a dynamic job destination in job_conf.xml's section:

 python
 ncbi_blastn_wrapper
Note that any parameters defined on dynamic destinations are only available to the function. If your function dispatches to a static destination, parameters are not propagated automatically.
Next for any tool one wants to dynamically assign job destinations for, this blast dynamic destination must be specified in the job_conf.xml's section:

Finally, you will need to define a function that describes how ncbi_blastn_wrapper should be executed. To do this, one must create a python source file in lib/galaxy/jobs/rules, for instance destinations.py (though the name of this file is largely unimportant, one can distribute any number of functions across any number of files and they will be automatically detected by Galaxy).
So open lib/galaxy/jobs/rules/destinations.py and define a ncbi_blastn_wrapper function. A couple possible examples may be:
from galaxy.jobs import JobDestination
import os
def ncbi_blastn_wrapper(job):
 # Allocate extra time
 inp_data = dict( [ ( da.name, da.dataset ) for da in job.input_datasets ] )
 inp_data.update( [ ( da.name, da.dataset ) for da in job.input_library_datasets ] )
 query_file = inp_data[ "query" ].file_name
 query_size = os.path.getsize( query_file )
 if query_size > 1024 * 1024:
 walltime_str = "walltime=24:00:00/"
 walltime_str = "walltime=12:00:00/"
 return JobDestination(id="ncbi_blastn_wrapper", runner="pbs", params={"Resource_List": walltime_str})
from galaxy.jobs import JobDestination
import os
def ncbi_blastn_wrapper(app, user_email):
 # Assign admin users' jobs to special admin_project.
 admin_users = app.config.get( "admin_users", "" ).split( "," )
 params = {}
 if user_email in admin_users:
 params["nativeSpecification"] = "-P bigNodes"
 return JobDestination(id="ncbi_blastn_wrapper", runner="drmaa", params=params)
The first example above delegates to the PBS job runner and allocates extra walltime for larger input files (based on tool input parameter named query). The second example delegates to the DRMAA job runner and assigns users in the in the admin list to a special project (perhaps configured to have a higher priority or extended walltime).
The above examples demonstrate that the dynamic job destination framework will pass in the arguments to your function that are needed based on the argument names. The valid argument names at this time are:
Global Galaxy application object, has attributes such as config (the configuration parameters loaded from config/galaxy.yml) and job_config (Galaxy representation of the data loaded in from job_conf.xml).
E-mail of user submitting this job.
Galaxy model object for user submitting this job.
Galaxy model object for submitted job, see the above example for how input information can be derived from this.
An object meant a higher level utility for reasoning about jobs than job.
Tool object corresponding to this job.
ID of the tool corresponding to this job
Utility object with methods designed to allow job rules to interface cleanly with the rest of Galaxy and shield them from low-level details of models, metrics, etc….
A dictionary of parameters specified by the user using job_resource_params_conf.xml (if configured).
A randomly generated UUID for the workflow invocation generating this job - this can be useful for instance in routing all the jobs in the same workflow to one resource.
Also available though less likely useful are job_id.
The above examples demonstrated mapping one tool to one function. Multiple tools may be mapped to the same function, by specifying a function the the dynamic destination:

 blast_dest

In this case, you would need to define a function named blast_dest in your python rules file and it would be called for all three tools. In cases like this, it may make sense to take in tool_id or tool as argument to factor the actual tool being used into your decision.
As a natural extension to this, a dynamic job runner can be used as the default destination. The below examples demonstrate this and other features such as returning mapping failure messages to your users and defaulting back to existing static destinations defined in job_conf.xml.
Additional Dynamic Job Destination Examples
The following example assumes the existence of a job destination with ids short_pbs and long_pbs and that a default dynamic job runner has been defined as follows in job_conf.xml:

 default_runner
With these if place, the following default_runner rule function will route all tools with id containing mothur to the long_pbs destination defined jobs_conf.xml and all other tools to the short_pbs destination:
def default_runner(tool_id):
 if'mothur' in tool_id >= 0:
 return 'long_pbs'
 return'short_pbs'
As another example, assume that a few tools should be only accessible to developers and all other users should receive a message indicating they are not authorized to use this tool. This can be accomplished with the following job_conf.xml fragment

 dev_only

Coupled with placing the following function in a rules file.
from galaxy.jobs.mapper import JobMappingException
from galaxy.jobs import JobDestination
DEV_EMAILS = ["_EMAIL_"]
def dev_only(user_email):
 if user_email in DEV_EMAILS
 return JobDestination(id="dev_only", runner="drmaa")
 raise JobMappingException("This tool is under development and you are not authorized to it.")
There is an additional page on Access Control for those interested.
Additional Tricks
If one would like to tweak existing static job destinations in just one or two parameters, the following idiom can be used to fetch static JobDestination objects from Galaxy in these rule methods - dest = app.job_config.get_destination( id_or_tag ).
Limiting Job Resource Usage
The collection defines the number of concurrent jobs users can run, output size limits, and a Galaxy-specific limit on the maximum amount of time a job can run (rather than relying on a DRM's time-limiting feature). This replaces the former job_walltime, output_size_limit, registered_user_job_limit, anonymous_user_job_limit configuration parameters, as well as the (mostly broken) [galaxy:job_limits] section.
NB: The job_walltime and output_size limits are only implemented in the local and pbs job runner plugins. Implementation in other runners is likely to be fairly easy and would simply require a bit of testing - we would gladly accept a pull request implementing these features in the other provided runner plugins.
The collection has no attributes.

Return to Profitability Reduce CoGS and Increase Margins with Menu Engineering and AvT Analysis
Complete the form to view this on-demand webinar
Tracking actual vs. theoretical (AvT) food costs helps you identify and correct waste, errors, over-portioning and theft. Menu engineering helps maximize profitability by promoting your most profitable menu items and encouraging customers to buy what you want them to buy. Using these two key complementary approaches to optimize menus and simultaneously evaluate food cost, you can reduce food costs and sell more of your high margin items. During this on-demand webinar you will learn:
 - Menu engineering not only helps you understand the profit on individual menu items, but also analyzes how these individual pieces interact and affect profitability on the menu as a whole. This is a "top-down" approach that focuses on increasing revenue.
 - Actual versus Theoretical variances track the difference between what you spend on food and beverages vs. what you should have spent. This is a "bottom-up" approach that helps control costs.

In the field of engineering (mechanical), a key is an element of the machine that connects a rotating element to a nearby shaft. The key, therefore, prevents the relative rotation between these two parts and may allow torque transfer. For a key to work, the shaft and the rotating member of the machine must have a keyseat and a keyway, which are a slot and a pocket in which the key can fit into. The entire system is known as a keyed shaft or joint hinge. Keyed shafts allow relative axial movements between the parts involved.
The most common key components are pulleys, gears, clutches, and washers.
How are keyed shafts cut? Find below the process involved in keyed shaft cutting.
Keyseating (for big and special keyways)
This is done by cutting the keyway with a key-operated device which removes the material through a series of tooth-cutting movements. Some keys have only one cutting tool, while other machines (such as the Davis Keyseater) use a multi-cutter to make cutting speeds as fast as broaching.
Here's how it works, The Keyseater cutter moves slowly outward at every cut. This subtle movement makes it possible for every stroke to remove a little more material. This process is then repeated until there is a cut deep enough to satisfy the specifications required for its application.
The main advantage of Keyseating is in the fact that it offers maximum flexibility for largely specialized keyways. The custom tooth cutters are quite easy to get and can even be quickly adapted to the specific requirements even when you're on an onsite tool room. Depending on the type of machine, however, and the cutting tool, the Keyseating may need a longer cycle time than conventional broaching.
Shaping –for the blind keyways.
Shaping is a nice option for the cutting of blind keyed shafts. Blind in this context refers to the keyways which are not required to go the all the entire length of the way or part. Some of the keyed shaft cutting process, such as the EDM and the broaching is not designed for blind keyways handling.
Like it is with some keyseaters, this shaping uses only a single tooth as its cutting tool. But unlike others, shaping is not required to be guided down through the cuts on a fixed post. Consequent of this, the shaper cuts cannot reach the same height of accuracy as the keyseater cuts because of the unguided deflection. Therefore, this heightens the need for a proper tolerance inspection.
To cut blind keyways, usually, shapers require that users cut a "relief" at the end of the keyway that is soon to be cut. The relief makes it possible to break the fragments of the metal. You can form them by pre-drilling a hole or cutting an internal groove right inside the inner diameter
Milling (this is for shaft only keyways)
As for milling, like shaping, users are allowed to cut partial length, straight keyways or tapered. Milling is well known for the ability to cut external keyed shafts or keyways. But then, milling inside a diameter keyway on hubs is not common, the reason for this that the other side of the coupling always gets in the way. However, if it is needed, an internal hub keyway may be milled using a special 90degree singular milling head.
As with shaping, quality is a very important factor to take into account when milling keyed shafts, because of the lack of unguided cuts. Tolerances, like the corner radius quality, require special attention to ensure correct formation in line with the desired specification. Otherwise, problems may arise, for example, a key that does not match or an imbalance in the power transmission system.
Wire EDM (for small special runs)
Keyed shaft cutting with wire electric discharge machining (i.e EDM) is typically used for small quantities parts which require precision or some other specific cutting options. The tool and die manufacturers use EDM wire to remove materials through a process that may be called "shock" or "evaporation". With this process, a coiled copper wire is brought to cut the target using electric sparks, without however directly touching the component.
We hope that this guide has given you an insight into keyed shaft cutting. If you need a way to reduce cycle time or want to cut keyways or shafts, want to reduce manufacturing costs, then contact us via phone or email. We'd guide you on which option is best for you.

This report documents the methodology, findings and conclusions of the Starting to smoke research project. The aim of the project was to explore the reasons young Indigenous people in the Northern Territory start smoking as well as the protective factors which prevent smoking. Young people aged 13-20 years of age were recruited from urban and remote communities to participate in one-on-one and group interviews.
A particular focus of the project was on the social and cultural processes that influence smoking uptake in this group. Based on the project's findings, the report makes recommendations regarding future smoking prevention initiatives. The project was carried out in the Northern Territory across two sites: one in Darwin and one in a remote community in Arnhem Land.

This Policy Framework from the Ministry of Justice sets out the minimum mandatory requirements required to provide education and library services in adult prisons in England. It is primarily aimed at governors and their staff and describes the policy requirements and legal duties expected of them to be able to deliver education services in their prisons. There are separate policy frameworks for prisons in Wales, Immigration Removal Centres and youth custody estates.
Those expected to adhere to this framework includes governors, heads of groups, the women's estate, public sector prisons and over 18s young offender institutions and contracted prisons in England. This framework replaces document 'PSI 20/2000 Education Key Performance Indicator: Measuring basic skills attainment'.
The framework can help with the implementation of reforms that give governors more control over education delivered in their prisons. It also allows them to provide an effective strategy for their prison's education programme. The outcomes of using this resource are as follows:
- Prisons will be able to offer education that is aligned with the needs and interests of its prisoners, and relative to the employment markets that prisoners enter upon their release.
- Prisoners will be engaged in the learning process and able to achieve personal, employment and learning goals and sustain employment following their release.
- Prisoners will feel encouraged to build life skills and develop their own sense of wellbeing, social capital and employability, as well as reduce the risk of reoffending.
- Prisoners will have access to well-stocked libraries and use the materials within them to support their learning journey.
- Prisoners will have the opportunity to read for pleasure and improve their literacy skills.
The Prison Education & Library Services for adult prisons in England Policy Framework also contains links to other useful supporting documents and provides details about materials supplied on the HMPPS intranet.

High Performance Leadership of the Elephant
High Performance Leadership of the matriarch is all-important. High Performance Leadership means that the matriarch, the oldest and most experienced elephant, indicates direction, 'coaches' the herd towards a new goal, monitors the solidarity of the herd and leads strongly by example.
What are the characteristics of this High Performance Leadership behavior?
The matriarch always acts in the interest of the group, is in the lead to protect the herd, is result-oriented, decisive and establishes a clear framework. For instance, the matriarch indicates when and where the herd will stop to drink or sleep, and when they will continue walking. This is HPO (High Performance Organization) behavior that serves to protect the next generation.
In short: A successful High Performance leader builds relationships of trust by combining honest and coaching leadership with strong role-model behavior, fast decision-making (also regarding non-performers) and result orientation, all of which is based on a long-term vision.

 # Expected output is 11.
 output = tf.tpu.outside_compilation(computation_with_string_ops, 1)
Outside compilation should be called inside TPUReplicateContext. That is, tf.tpu.outside_compilation() should be called inside a function that is passed to tpu.split_compile_and_replicate() -- this is implied when outside compilation is invoked inside a function passed to TPUStrategy run(). If invoked outside of TPUReplicateContext, then this simply returns the result of computation, and therefore, would be a no-op. Note that outside compilation is different from tf.distribute.experimental.TPUStrategy.merge_call() as logic in outside compilation is replicated and executed separately for each replica. On the other hand, merge_call() requires a merge_fn to aggregate the inputs from different replicas and is executed only once.
For variables placed in TPU device, which includes variables created inside TPUStrategy scope, outside compilation logic must not include variable read/write. For variables placed on host, which is the case when variables created via TPUEstimator, variable read/write is only allowed if the variable is not accessed by any other ops in the TPU computation. Variable read/write from outside compilation cluster is not visible from TPU computation and vice versa. Therefore, if outside compilation logic contains such host variables read/write ops and if the variables are accessed by TPU computation as well, then this may lead to deadlock.
Internally, tf.tpu.outside_compilation() adds outside compilation attributes to all ops in computation. During later graph pass, these ops with outside compilation attribute is extracted out and replicated into a host-side graph. Inputs to this extract host-side graph is sent from TPU computation graph to host graph via a pair of XlaSendToHost and XlaRecvFromHost ops. Note that using tf.tpu.outside_compilation() may result in tensor transfer between TPU and CPU, leading to non-trivial performance impact.
computation A Python function that builds the computation to place on the host.
*args the positional arguments for the computation.
**kwargs the keyword arguments for the computation.
The Tensors returned by computation.


Allowing parallel iOS UI tests runs in CI
If you have your CI machine set up to run multiple jobs in parallel you might have encountered a problem. You cannot run multiple iOS UI tests in the same simulator at the same time. They will fail.
The problem
Imagine this scenario. You have one CI machine that allows two or more jobs to run in parallel. You have a UI tests job set up. Two of your developers push changes to their branches at (almost) the same time. The CI machine then tries to run two UI tests at the same time in the same simulator and at least one of them fails and has to be retried.
You can of course solve this problem by not allowing parallel jobs on the CI machine, but that slows down the CI process. There is a better way.
The solution
You can create a brand new iOS simulator instance for every job, run the UI tests in this new simulator instance and then delete it when you are done. This way no matter how many iOS UI tests jobs you run in parallel they will all use a separate iOS simulator instance and not affect each other.
Creating a new iOS simulator instance
The first step is to choose a unique simulator name for each job. You can generate some random guid for example. In Gitlab CI I just use the ID of the Gitlab CI job that is stored in the ${CI_PIPELINE_ID} environment variable
First you need to create the new iOS simulator instance at the start of the CI job
xcrun simctl create ${CI_PIPELINE_ID} 'xcrun simctl list runtimes | grep iOS | awk '{print $NF}''
This command creates a new iOS simulator instance with the given name using the iPhone 11 device and the latest simulator runtime. Using the latest simulator runtime makes sure that when you update Xcode on the CI machine you do not have to do any changes to you CI scripts.
Using the new iOS simulator instance
Now that you have a new iOS simulator instance created you can use it to run your iOS UI tests. You can simply pass the name to the xcodebuild command if you use it directly or use it instead of the device type when using Fastlane

Reading environment variables from iOS and macOS unit tests
In some environments like the CI/CD you might need to read environments variables from your iOS or macOS unit tests.
A typical example might be reading secrets or configuration that is CI/CD specific and you do not want to store it in source control.
In Swift you can read environment variables using the ProcessInfo.processInfo.environment dictionary, for example
let host = ProcessInfo.processInfo.environment["apiHost"]?? "default fallback host"
The problem is this code does not just work, there is one other step you need to do first.
You need to edit your Test scheme and add every environment variable you want to read to the Environment Variables section.
You can rename the variables but for simplicity and readability you should probably keep the same names.

Graying out images in Cocoa
I have been working on a macOS application recently where I encountered an interesting task to grey out flags for countries that are disabled.
I first tried overlaying a semi-transparent gray view (fun fact, you cannot directly set a background for a view in Cocoa, you need to use the layer) over the flag image but it did not look very good.
Luckily there is a way to convert a NSImage to grayscale directly in Cocoa.
You first need to create a bitmap representation your NSImage
let bitmap = NSBitmapImageRep(cgImage: cgImage)
convert it to grayscale
let grayscale = bitmap.converting(to:.genericGray, renderingIntent:.default)
and then construct an NSImage from the result.
let grayImage = NSImage(size: grayscale.size)
Putting it all together as an NSImage extension might look like this

Web scraping with Swift
In a few projects in the past I needed to do web scraping to get some data from websites that did not offer access via an API. I was using C# at the time and scraping web with Html Agility Pack was quite easy.
I now spend most of my time in macOS because of work projects so when I needed to do some web scraping again I did not want to install and set up Mono to do it again in C#. I decided to go with Swift, as I am now quite comfortable with the language after 4 years of using it daily.
The first thing I need to do was to found some library to parse HTML, some Swift equivalent to Html Agility Pack. I found SwiftSoup.
SwiftSoup allows you to access DOM in HTML documents and also HTML fragments. The usage is quite simple, you just need to know a thing or two about HTML.
Let's say you want to parse the Hacker News main page and scrap posts containing some specific keywords.
This is quite an artificial example but the idea is simple. You use the developer tools in your browser of choice to see the HTML of the parts of a website that you are interested in and try to get to them descending and filtering the DOM using SwiftSoup.
You first need to read the website and parse it
let content = try String(contentsOf: URL(string: "")!)
let doc: Document = try SwiftSoup.parse(content)
Looking at the HTML you can see it uses a table layout and all the posts are in a rows of a table with a class called itemlist.

Generating boilerplate Swift code with GYB
How many times how you copied and pasted some code in your current codebase because there was no good way to abstract it? Maybe because it was some repeating code required by a framework or mapping of some data transfer structures.
Writing such boilerplate code is an error-prone waste of time, especially when there is a much better way: generating that code.
There are a few tools to help you do that, one of the most flexible of them being GYB.
What is GYB?
GYB is a lightweight templating system that allows you to use Python to generate text files. Those text files can be Swift source code files or anything else you need.
GYB is used in the Swift standard library codebase so it works well for generating Swift source code and it is a proven technology that works.
You can download GYB to your project from the Swift repository on Github
chmod +x gyb
I put it directly to the project directory and include it in the source control for simpler build and CI/CD setup.
Creating GYB templates
GYB templates for generating Swift source file look like Swift source files with some Python snippets for code generation.
This is probably best shown on an actual example. Let's say you have a list of permissions that the app needs to support. Those permissions are then a part of a protocol and of a few structs.

Tyre Deflators
TRAILHEAD Automatic Tyre Deflators will automatically reduce the air pressure in a tyre to a predetermined level and stop, preventing any further loss of air from the tyre. They will function properly whether your vehicle is stationery or traveling at speeds of around 30km per hour or less.
Trailhead Automatic Tyre Deflators
The shut off pressure on your tyres may vary due to several factors, especially the flow rate of your valve stems.
1. Turn adjusting screw with a 5/32" allen wrench counter clockwise until it is even with the end of the body tube. This will set pressure at the lowest end of the adjustment range. Every complete turn clockwise will increase pressure approximately 1.5psi for the 5-20psi
range, and 3psi for the 15-40psi range.
2. Turn the adjustment screw clockwise the desired number of turns and follow "OPERATING INSTRUCTIONS".
3. If tyres have not deflated to the proper value, make minor adjustments to the adjustment screw, re-inflate and re-test. Some experimentation may be necessary to find the exact setpoint. This process goes quickly if a small spare tire (i.e. wheel barrel tyre, ATV tyre, etc.) is for use during the adjustment process. This process should take about 15 minutes as opposed to over an hour using a full size off road tyre.
NOTE: In order for deflators to reliably begin operation, tyres must be inflated to a pressure approximately twice the setpoint, e.g. If the deflators are set to shut off at 10 psi, tyres must be inflated to approximately 20 psi or greater.
1. Remove valve caps and replace with one tyre deflator on each tyre.
2. Wait until deflators are finished deflating and remove them from the valve stems.
3. Check pressure and make any adjustments to tyre pressure or deflators setpoint as necessary.
Consistency is more important than accuracy. Usually it is more important to have both tyres on a given axle deflated to the same pressure than to be exactly at the setpoint. Be sure to make every measurement the same way, every time. Consistency and repeatability are greatly improved when the valves on all four tires are from the same manufacturer and lot. This will minimize differences in the rate of flow from tire to tire that cause inconsistent readings.
1. Remove adjustment screw & spring while noting the number of turns the adjustment screw was inserted. Remove ball valve by blowing air into the knurled end of the deflator. Keep one hand over the open end to catch the ball and prevent loss. Make every effort to keep the components of each deflator together for reassembly later.
2. Thoroughly clean inside the deflator's bore with a Q-tip and rubbing alcohol, then compressed air. Clean all components with rubbing alcohol and compressed air.
3. Apply a fine coating of a high quality, heavy silicone or teflongrease or Vaseline, or a similar lubricant to each ball valve.
4. Insert the stem of the ball valve into one end of the spring and slide this assembly into the deflator, ball end first.
5. Install adjustment screw (the same number of turns before it was disassembled).


How to keep your fiddle-leaf fig alive and happy
There's no denying fiddle-leaf figs were the indoor "it plant" of 2017 and they're still a favourite today.
Known mainly for it's shady dark green leaves, veiny leaftlets and hefty price tag, this fashionable foliage has proved to be quite the challenge for some. To make sure you're giving your fiddle-leaf all the TLC it needs, Yates horticulturalist Angie Thomas shares tips on how to look after your very own.
Why choose a fiddle-leaf?
"Fiddle leaf figs (Ficus lyrata) are fantastic, large leafed figs that make a wonderfully bold statement when grown as in indoor plant."
How to nail the positioning
"They love a spot indoors that's well lit but protected from direct sunlight. It's a good idea to rotate the pot around, by half a turn, every fortnight so that each side of the plant receives some light. This will help reduce the chance of lop sided growth."
The fiddle-leaf fig is a plant that makes a big statement. (Leon&George)
What not to do
"Fiddle-leaf figs don't like drafts from windows or air conditioners. They're native to humid tropical rainforests, so they love a protected humid environment."
How often should you water a fiddle-leaf fig?
"Over watering your fiddle-leaf fig is courting disaster! Only re-water when the top few centimetres of potting mix feels dry. I highly recommend feeding your fiddle leaf fig during the warmer months of the year with a liquid fertilizer."
Uh-oh! So it's started to "sulk" - how to salvage your fiddle-leaf:
"Figs can be temperamental if they're moved. 'Weeping' figs are notorious for dropping their leaves when they're moved and fiddle-leaf figs can also sulk and lose some of their leaves if you move them.
"If your fiddle leaf fig is not liking its current spot and is not looking happy, then move it to a better location (such as with brighter light or away from a draft). Otherwise, try to avoid moving your fig or if you do have to move it, do it gradually and hope it doesn't notice!"

Gas Secretion and Absorption
One clear advantage of having a swimbladder is that little to no extra energy is necessary in order to remain stationary at a constant level of water. Only a slight control by use of the pectoral fins is required to balance out the propulsive force of water exiting the gills. Fish with no swimbladder on the other hand, such as mackerels, sharks, and rays must expend energy by constantly swimming in order to keep from sinking.
| Another advantage of swimbladders is
oxygen storage. Physoclists and physostomes alike may occasionally
use the oxygen present within their bladder as an emergency backup in times
of urgent need, although, this emergency store can only be of aid for a
few minutes (Jones 1957).
Finally, swimbladders in some fish are known to increase hearing abilities. With the presence of inner earswimbladder connections, these fish have exhibited greater sensitivity to sound, however it is not yet clear whether there is also an increase in frequency selectivity (Coombs & Popper 1982a)

Speech my aim in life can be a dicey one. Since the presenter may have a particular aim that the audience might find unrelatable or irrelevant to them according to their perspective. Ambition is often associated with a negative terminology of one being greedy and selfish. The speaker who is assigned to deliver my aim in life speech can focus on the direction ambition can give to an individual. Ambition surely is a very individualistic process of discovering one aim, especially for a student. In this article, of speech on aim in my life, we will explore different ways of delivering it. It can be a long speech on aim of life student or a short my aim in life speech.
Long and Short Speech on Aim of My Life
Long Speech on Aim of My Life
This type of long speech on aim in life can be helpful for students in grades 8-12 who can elaborate on the importance of aim and speak about their own ambitions as well.
Good morning everyone, respected principal, teachers, and my dear friends, I am Xyz (mention your name) here to talk about the aim of my life. Let me first ask all of you, my friends, what are your ambitions? Have you ever thought about what actually it is to have an aim in life is? Ambition is a very subjective term it means different to different people. The common ground for everyone when one thinks of aim is the desire to achieve something by doing something that they are passionate about and interested in.
It is a very common question that our peers and even elders ask what is your aim in life? Many people find it difficult to decide on one specific aim in particular some have multiple interests and want to excel in all, which is quite a task. I have always believed that instead of being a jack of all trades one needs to be a master of one.
I have always seen my elder brother having an aim throughout his school life. Sometimes it was to score well in exams, be the school captain and sometimes it was to get admission to his desired university. It was through him that I understood having ambition is so important, it is the source of inspiration and the driving force behind leading a fulfilling life.
Having an aim actually drives you to have a purpose in life and to continuously keep on working towards it. To discover your aim, one must explore different interests and keep on trying. One can have a short-term goal that can also be the aim to be fulfilled. And other kinds of ambitions can be professional or personal. People who are aimless have no driving force that inspires them to wake up every morning to get to work and fulfill their ambitions. And they often fall prey to the vicious cycle of lethargy, inactiveness, lack of motivation, or will to do better or get anywhere in life. And thus one must be ambitious.
I was also one among those who had many interests and tried to do everything, it was a challenge to sit still and actually think about something that I am truly passionate about and ambitious enough to achieve as well. I have always been philanthropic thanks to my grandfather who has always inculcated this value in me since I was a little girl/boy.
During one such visit with my grandfather where I was accompanying him to assist in his medical aid program to the underprivileged, I realized I want to do just this. I want to become a doctor just like my grandfather. It was a shocker for my family when I told them this, they reasoned saying since I was always into extracurricular activities and arts completely diving into such an academic route will require hard work and a lot of sacrifices.
Having an ambition doesn't make the mountain of hurdles and obstacles smaller it just makes the climb easier and gives strength to keep going. I am preparing and working hard in all the subjects that I need to for scoring well in the entrance exam. Only then I can attend a prestigious university.
Everything in life needs our effort, time, and patience no matter what field it is. Nothing is served on a silver platter, one might think it would be so much better to enjoy than to work hard. Well, decide what it is that you want to achieve, having an aim will make all the hard work worthwhile. I know some of my friends want to become, teachers, singers, actors, mathematicians, dancers, sportsmen. I wish you all the best to work and have patience even when it gets difficult.
Thank you.
Short Speech on Aim of My Life
This short speech on aim of life student will find it very easy to deliver and understand its meaning. Very helpful for students in grades 4-7.
Good morning everyone, I am ABC (mention your name) here to speak about the aim of my life. We all have dreams and multiple ones that we wish would come true. Ambition and aim on the other hand do not work like that, one cannot wish for it to come true. When dreams become realistic goals we can consider it as our aim in life to be achieved so we feel worthy and happy.
My aim in life is to become a teacher just like my mother, and all my teachers here have also played a part in me coming to realize my aim. My mother is the most important and inspiring person in my life. She is the best teacher, many of her students reach out to her even when they have something personal to share. A teacher is a teacher even beyond classrooms, I find so much beauty and depth in my mother's profession that it has inspired me to take upon this as my aim as well.
I also want to have a part and role in children's development and help them become responsible and accountable individuals. Teachers truly hold a reputation for being strict but when one has the responsibility of the next generation leaders of the country some level of strictness will push the students. The teacher understands when to be strict and when to be the student's friend. And they walk a tightrope in balancing all of this. I hope my inspiration will help me to work hard and achieve the aim of my life.
Thank you.
10 Line Speech on Aim of My Life
This easy 10 line speech is helpful for students in grades 1-3 for a better understanding of my aim in my life speech.
 1. Ambition is the willingness to achieve something in life depending on one's interest, it can be different for every individual.
 2. Having an aim makes one's life meaningful and filled with purpose.
 3. It inspires, motivates, and humbles an individual when they are trying to achieve something they have set their minds on.
 4. An aimless person is directed towards hard life with no purpose and no hope.
 5. Ambitions give us hope for a better future.
 6. For a better tomorrow, we need to put in the work today and be dedicated to it, and consider every challenge as an opportunity to get closer to achieving our ambitions.
 7. When you achieve your aim in life you feel honoured and empowered.
 8. People around you also respect a successful person who puts in the work to achieve and excel at anything they have set their mind to.
 9. My aim in life is to become a dancer, I have already enrolled myself in a course. Thanks to my mother who has always encouraged me to pursue my interests.
 10. I wish to become a renowned Kathak dancer and give stage performances on an international level and bring laurels to my country and make my parents proud of me.

Q: I need help identifying a bird I have at my feeder. It looks like a cardinal except for the head, which appears to be devoid of feathers! It has normal red body feathers and a head with no crest.
A: You have a male cardinal whose feathers have dropped off. This is the subject of lengthy discussion among birders but the consensus is that it can be caused by mites, heat or nutritional difficulties. The folks at Hilton Pond Center in South Carolina have observed several birds with this condition (which they call "lizard-head"), including one who was bald one year but fully recovered the next.

Major Section: ACL2 Documentation
Ordered binary decision diagrams (OBDDs, often simply called BDDs) are a technique, originally published by Randy Bryant, for the efficient simplification of Boolean expressions. In ACL2 we combine this technique with rewriting to handle arbitrary ACL2 terms that can represent not only Boolean values, but non-Boolean values as well. In particular, we provide a setting for deciding equality of bit vectors (lists of Boolean values).
Further information about BDDs in ACL2 can be found in the subtopics of this documentation section. In particular, see bdd-introduction for a good starting place that provides a number of examples.
See hints for a description of
:bdd hints. For quick
reference, here is an example; but only the

Bicycle stores -- Public relations, Neighborhoods -- Social aspects
The local bicycle shop (LBS) has long served its neighborhood as a retail establishment and service center, but little has been done to analyze its influence on the greater community. After examining the categories of people who cycle and frequent bike shops, a rough typology of the different kinds of bike shops often found in a city was synthesized. This paper examines the different roles or assets that a given shop can be in a neighborhood. From a third place or anchoring institution to advocate for and even component of cycling infrastructure, the LBS fulfills one or several of these responsibilities to its community. The definitions of these four community assets will provide insight into how the average bicycle shop might act as such. Specific shops in the city of Portland are then carefully examined through observation and staff interviews to determine the extent to which these roles are actually performed. This paper suggests that a community that wishes to establish or maintain itself as friendly towards cycling should recognize the LBS as a crucial part of that image by providing a unique place for all people to gather, socialize, and exchange knowledge.

The Portsmouth Gaseous Diffusion Plant is located in south central Ohio, approximately 32 kilometers (20 miles) north of Portsmouth, Ohio, and 112 kilometers (70 miles) south of Columbus, Ohio. The site is situated on a 1,483-hectare (3,708-acre) federal reservation
approximately 6.5 kilometers (4 miles) south of the Village of Piketon. Construction of the Portsmouth Gaseous Diffusion Plant began in late 1952 to expand the Federal Government's gaseous diffusion program already in place at Oak Ridge, Tennessee and Paducah, Kentucky. The facility was built to increase the production of enriched uranium at rates substantially above the other two facilities because highly-enriched uranium was required for use in nuclear submarine reactors, and low-enriched uranium was needed for commercial nuclear power plants. The first process cell went online in September 1954. A gas centrifuge uranium enrichment program was initiated in the early 1980s at Portsmouth. However, full operation was never implemented for the centrifuge process. Since 1991, the plant has produced only low-enriched uranium for use as fuel in commercial nuclear power plants.
