Pearl River Church was built in 1833 as a school near the Natchez Trace in Madison County and school and church shared the facility. It has been used as a Methodist church throughout its history, although it is no longer used except for special occasions. The building was remodeled in 1889 to its present form. It is noted for its role in the history of the Lambuth family particulary. From this church in 1854 Rev. and Mrs. James William Lambuth went as missionaries to China where their descendants continued to labor long afterward. On a return trip to Mississippi and a stay of two years, daughter Nettie died and is buried in the adjacent cemetery. In honor of the Lambuths, each third Thursday of October there is a memorial service known now as Lambuth Day: The service has been essentially continuous since its beginning 1900. A monument in front of the church memorializing the Lambuths was installed at that time.

The envelope theorem is used to solve maximization problems in the fields of microeconomics and finance. It is a fundamental result in the calculus of variations and is therefore often used in large deviations research.
We verify that the envelope theorem holds for the log-likelihood function when the underlying data are generated from a normal distribution. The evidence that the theorem is true is that the top and bottom pictures in the Demonstration are identical.
We explain the envelope theorem by way of a concrete example.
The log-likelihood maximization problem is to find parameters such that
Fix and define a new function such that
Now we view. Then the envelope theorem says that
The functions and are plotted in the top and bottom parts of the Demonstration output, respectively.
Roughly speaking, then, the envelope theorem says that fixing, maximizing over, and then taking the derivative with respect to is the same as taking the derivative with respect to, then fixing, and then substituting for the fixed the particular that maximizes.

Manage Multiple Social Accounts-01
By nature, social media managers are multitaskers. They're constantly juggling the need to engage with customers, publish new content, analyze success, monitor conversions, report to stakeholders and–if time allows–sleep. Not only do most social media managers have to complete these activities, but many of them do all of that work for multiple social profiles and networks.
What drives this need for multiple social media profiles and networks? Surely companies aren't creating superfluous accounts to generate more work for their communications teams.
This article is going to dive into which circumstances companies would need multiple social media accounts, give some examples of specific business types that benefit from a larger presence and most importantly, look into how you can effectively manage multiple social media accounts.
Why Do You Need Multiple Social Accounts?
Creating multiple social media accounts gives you much more control over the type of content that corresponds to various products, locations or departments of your company. We'll get into examples of specific organizations that frequently use multiple social media profiles, but here are a few reasons why a company may go that route.
 - Multiple products – if you have several different popular products that get asked their own questions or that need to create their own content.
 - Multiple locations – if you have multiple locations that all offer different promotions or have different hours that need to be shared.
 - Different goals – different portions of your business may have their own unique goals when it comes to social, and may require a different strategy.
 - Different social voices – each product or portion of your business may have a different "social voice." For instance, one brand voice may err on the serious side, while another could have the chance to be more humorous and lighthearted.
 - Different teams – each team within an organization–like customer service, human resources, or research & development–may want their own social presence to better control the flow of conversations and content.
Those are just a handful of the many reasons why companies may want to create multiple profiles on each social network. To paint a better picture of this, it's helpful to look at specific examples of who needs multiple accounts.

Who Needs to Manage Multiple Social Accounts?
The idea of creating multiple social media pages may seem trivial–you're essentially just creating more work for yourself–so who would do it? There are a lot of reasons why a company may want to split their online personalities into multiple social media pages.
1. SMBs
The most common reason a smallor medium-sized business creates multiple social media pages is to separate unique portions of their business. A company may give their blog a separate handle so they can distribute their content more frequently to those that want to read it. SMBs may also give their customer support team a separate handle so their main page isn't bogged down with customer service issues.
2. Corporations
Corporations could use multiple pages for the same reasons as SMBs, but there are a few more use-cases unique to this group. Some corporations, for instance, could use the social media profiles of a C-level employee to share company-wide news and updates.
Corporations could also create new profiles for some of their different departments–like human resources, R&D or finance–who can handle the messages better suited for their team.
3. Franchises
A lot of major corporations with several locations will create unique social profiles for the various branches of their business. McDonalds, for instance, has several location-based Twitter pages, including accounts for different countries, states and cities.
This gives the franchises the freedom to post about exclusive deals, operating hours or contests that the entire organization may not participate in. That frees up the corporate pages to continue creating content that advocates for the success of the individual franchises.
4. Agencies
The whole idea of agencies is that they can manage the work for multiple companies all at once–freeing those companies to work on the other functions of their business. So, it should come as no surprise that most agencies need to manage multiple social media profiles simultaneously. Some of the larger agencies can even be responsible for handling hundreds of different social pages at once.
5. Universities
This is one of the most popular use-cases for needing multiple social media profiles. Universities have so many different sub-organizations with different needs and voices that could require unique social media pages.
Here are a few more instances of different social media accounts universities could own:
 - Student clubs and organizations
 - Student services, such as housing and dining
 - Student newspapers
 - College programs
 - Libraries and buildings
 - Residence halls
 - Alumni groups
 - Emergency notifications
 - Athletics
 - Even accounts for the mascot!
Another example would be Harvard, which has more than 100 different social media profiles built out for the various organizations at their university.
How to Manage Multiple Social Media Accounts
At a high level, the key to managing multiple social media accounts simultaneously is to utilize a single stream social media management platform. The functionality to handle multiple pages all at once just isn't available on most networks, especially when you're talking about combining multiple social media sites such as Instagram, Facebook, Twitter and LinkedIn. At Sprout Social, we've created our own social media software for handling these exact needs.
We feel like we have a good idea about what makes social media managers tick. Our platform was built to make managing multiple social profiles easier, especially when there are several accounts tied to a single business.
If you're interested in diving into the platform to test it for yourself, check out our completely free trial–no need to download any software or enter credit card information.
Engaging on Multiple Social Media Accounts
The most important thing you can do on social media is engage with your current and prospective customers in order to build lasting, profitable relationships. However, that can be difficult when you're managing several social network accounts across different platforms. Without any sort of tool, you'd find yourself constantly logging in and out of your various pages to find and field important messages.
That's a lot of time spent entering email addresses and passwords, which can be annoying when doing it just once. Additionally, you run the risk of accidentally promoting one social profile while logged into the other–or even worse–post personal social messages on corporate feeds.
You need a way to centralize the messages sent to all of your social profiles and that something could be Sprout Social's Smart Inbox.
You can easily work your way through every message sent to all of your profiles by yourself, or with a team, and mark them as complete as you go. This will help ensure you never miss an important social interaction.
Publishing to Multiple Social Media Accounts
Most of the different pages you manage require unique content, because what's relevant for one audience may not be relevant for another. Without a social media tool, it could take all of your time finding, creating and sharing content across multiple different accounts.
However, with Sprout Social you can queue, schedule and publish all of your content to multiple social media networks simultaneously from within the platform. This will save you countless hours you could have used to engage with customers to grow relationships.
Analyzing Multiple Social Media Accounts
With social media marketing, it's important to look at what has worked in the past so you can utilize that success moving forward. Analyzing the data you have at hand is key in creating more successful campaigns moving forward. Unfortunately, collecting and analyzing data for multiple pages is cumbersome.
Sprout's social media analytics suite makes it easy to view your data on a profile level so that you can see what specifically works for your individual social pages. Not only that, but you can combine that data with our group and roll-up reports to see what is working across all of your profiles and campaigns.

Collaborating on Multiple Social Media Accounts
The key to managing multiple social media profiles is teamwork. Even if you can't convince your company that you need more social media managers, try recruiting some internal teams to help out when queries come in relating to their department.
Sprout's collaboration was made for multiuser teams to work within all at once. Manage the Smart Inbox as a team, create internal notes, task specific messages to the proper departments, run reports to see how everyone is performing, and take out all of the stress of double-responding with collision detection features.
Get Managing
There are plenty of reasons why a company may need manage multiple social media accounts, and without the right management platform, things can get hairy. So try and figure out which parts of your organization would thrive with their own social media presence and get them established online. Once these members have their own space to work, they can work freely in your social media management platform!

在75%RH、30 ℃条件下通过相互选择性实验、单独饲养和混合饲养实验研究赤拟谷盗和玉米象在小麦中的相互关系。研究结果表明：在相同生态环境中，赤拟谷盗和玉米象间的相互选择行为不明显。在小麦中单独饲养情况下，赤拟谷盗种群中成虫数量随处理时间延长先减少后增加，且增长缓慢，在处理56 d后最大成虫数量增加为起始虫数的11.5倍；而玉米象种群中成虫数量随处理时间延长而显著增加，在处理56 d后最大种群中成虫数量增加为起始虫量的53.9倍。与单独饲养相比，在小麦中混合饲养时，赤拟谷盗和玉米象的繁殖速率和种群中成虫数量都显著增加，在处理56 d后最大种群中成虫数量分别增加为起始虫量的20.3倍和93.4倍。因此，赤拟谷盗和玉米象均为小麦储藏过程中重要害虫，玉米象的危害对赤拟谷盗种群增长有促进作用。
The relationship between T. castaneum and S. zeamais was studied through reciprocal selectivity experiment, single rearing and mixture rearing at 30 ℃, 75% RH. The results showed that the mutual selection behavior between the two species was not obvious in the same ecological environment. The number of T. castaneum adults in the population decreased first, then increased slowly with increasing treatment time, the maximum number of adults in the population reaching 11.5 times of the initial number after 56 d rearing alone in wheat. while the number of S. zeamais adults in the population increased obviously with increasing treatment time, and reaching 53.9 times of the initial number after 56 d rearing alone in wheat. Compared with rearing alone, the number of adults in the population of both T. castaneum and S. zeamais significantly increased under mixture rearing in wheat, the maximum adults in the population reaching 20.3 and 93.4 times of the initial number respectively after 56 d. Therefore, both T. castaneum and S. zeamais are important pest insects during wheat storage, and the S. zeamais infestation can promote the growth of T. castaneum population.

Programming and Tech Tips
Use Hazel to Unzip Lots of Zip Files
Q: I have a lot of zip files deeply buried within hundreds of folders. Is there a way to unzip all of them easily?
A: Hazel can do this pretty easily with just two rules on the parent folder of all the subfolders.
First, create a rule called "Process Zip" with these settings:
Hazel Process Zip
If all of the following conditions are met:
Do the following:
The reason to tag the file is to prevent Hazel from getting stuck in an infinite loop if the zip file is damaged or otherwise can't be unarchived. I like to put the zip file in a subfolder of the same name to keep all the expanded files together.
Second, create a rule called "Subfolders" with these settings:
Hazel Subfolders
If all of the following conditions are met:
Do the following:
This will make Hazel look through every subfolder, finding every single zip file.
It is important to note that the Unarchive command in Hazel automatically moves the zip file to the trash once it has been expanded. You can change the Unarchive command to Open with default application to keep the zip, but this will open a new finder window for every zip, which is very annoying when you have a lot of zip files.
Question or Comment?


This is intended to provide information for people who throw Not An Answer (NAA) flags and who might be surprised to see the canned decline reason "flags should not be used to indicate technical inaccuracies, or an altogether wrong answer", (or some other decline reason) as the response to the flag.
When should answers be flagged as Not An Answer and when should something else be done?
We see quite a lot of Not An Answer flags that shouldn't really have been thrown. The NAA flag should be thrown when the community lacks the tools to fix an issue e.g.
 - The answer is asking for additional information or making a comment on the question - we can convert to a comment.
 - Someone is saying I have this problem too/Did this ever get resolved/Thanks etc.
 - Someone is asking a new question.
You could flag these as not an answer but you could do better
 - The answer is a comment on another answer (please use other and let us know where it should go, use the share link).
 - The answer is additional information that should be an edit to the question. We can convert to edit so using other and letting us know is good, you could edit the information into the question yourself and then flag other and request deletion.
NAA flags shouldn't be thrown when the community has the tools to fix the issue e.g.
 - The answer provided is wrong.
 - The answer provided doesn't answer the question.
 - The answer is phrased as a question e.g. Did you try X or Y? Which is really a hint to the OP to do something.
You have the tools to deal with these: Downvote, leave a comment or both. If you have enough rep and you feel it necessary, you can cast a delete vote.
Additional Information: _URL_ Can we have an unambiguous, official ruling on what the "not an answer" flag is for?
 - 8
 The second bullet point in the part saying that NAAs shouldn't be thrown when the answer doesn't answer the question contradicts the FAQ:s text, where it says that answers may be removed if they are "not even a partial answer to the actual question". It'd be nice if the FAQ and the moderators could be in agreement... – Jenny D Mar 27 '13 at 11:04
 - _USER_: I believe we are, it only says may not will. – user9517 Mar 27 '13 at 14:31

 Well, yes, but you seem to be saying "should not", which IMHO is a ways off from "may". At the very least it's a bit confusing for a relative newbie. – Jenny D Mar 27 '13 at 14:36

 Nice post - we're working to educate and promote the proper use of not-an-answer flags. meta.apple.stackexchange.com/q/1629/5472 I'm a big proponent for keeping all the wrong answers online, searchable, but properly down-voted and explained as to how and why the post is incorrect. Just as many learn from a correct answer - knowing what the answer is not is equally beneficial to learning. – bmike Mar 27 '13 at 17:48
 - 6
 Great. So don't use NAA if the answer doesn't answer the question (?!) – vonbrand Mar 29 '13 at 0:31
 - 6
 It seems to me the confusion is the difference between "is a wrong answer" (which shouldn't be NAA) and "is not even a wrong answer", which is what I think should be NAA. – Jenny D Mar 31 '13 at 12:08
 - _USER_ I find that when a comment is an answer, many users tend to steal the answer in that comment and post it as their own answer. – AStopher Nov 10 '14 at 9:18
 - _USER_ That's entirely acceptable – user9517 Nov 10 '14 at 9:25
 - 1
 What is recommended when the "answer" does not even try to address the question? I am asking because I flagged NAA an answer telling how to list KBs, because the question was about to uninstall KBs. My flag was "declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer". – Law29 Jan 20 '16 at 18:44
 - 2
 _USER_ A downvote. – HopelessN00b Apr 27 '16 at 21:38
 - _USER_ That's just a wrong answer - downvote it. – user9517 Apr 27 '16 at 21:55
 - 1
 OK, so "Not an answer" should not be used to flag posts which are not answers to the question. That's illogical, but no matter. – Law29 Apr 28 '16 at 5:12

text: Electrocardiography (ECG) is a kind of electrical activities of the heart measured along the skin, and is also an important tool to diagnosis heart decease. In clinical, the conventional ECG electrode is generally used for measuring ECG signal. However, it requires skin preparation and conductive gels to reduce the impedance of the skin-Velectrode interface. These preparation procedures easily cause the inconvenience and discomfort for the user. Moreover, it also easily encounters the problem of conductive gels drying for long-term ECG measurement. In this study, a capacitive coupling electrode was proposed to measure ECG without contacting the patient body of the user directly. By using the proposed capacitive coupling electrode, ECG can be measured without any preparation and conductive gels. Finally, the electrical characteristic was validated, and ECG measurement was also tested in this study.


PhpStorm 2018.1 Help
Sass and SCSS in Compass Projects
PhpStorm supports development in projects structured in compliance with the Compass framework. This framework uses Sass and SCSS extensions of CSS.
Preparing for Compass development
The Compass framework is installed through the Ruby Gem manager, therefore you need to install Ruby first.
 1. Download and install Ruby.
 2. Specify a path variable for the folder where the Ruby executable file and the gem.bat file are stored. This lets you launch Ruby and Gem Manager from any folder and ensures that Ruby is successfully launched during compilation.
 3. Install and enable the Sass Support plugin. The plugin is not bundled with PhpStorm, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
 4. Install Compass.
 1. The installation is performed in the command line mode. To start the built-in Terminal, hover your mouse pointer over show tool window bars in the lower left corner of the IDE, then choose Terminal from the menu (see Working with Embedded Local Terminal for details).
 2. Type the following command at the command prompt:
 gem install compass
 The tool is installed to the folder where Ruby executable file and the gem.bat file are stored.
Setting up a Compass project
You can have a project set up according to the Compass requirements in two ways: create a new Compass project or create an empty project and introduce a Compass-specific structure in it. In either case, a project is set up through command line commands. Of course, you can set up a Compass project externally and then open it in PhpStorm.
During project set-up, a conf.rb configuration file is generated. You will need to specify the location of this file when integrating Compass with PhpStorm.
 - To set up the Compass-specific structure in an existing project:
 1. Open the desired project in PhpStorm.
 2. Open the built-in Terminal by hovering your mouse pointer over show tool window bars in the lower left corner of PhpStorm and choosing Terminal from the menu.
 3. At the command prompt, type:
 compass init
 - To create a Compass project from scratch:
 1. Open the desired project in PhpStorm.
 2. Open the built-in Terminal by hovering your mouse pointer over show tool window bars in the lower left corner of PhpStorm and choosing Terminal from the menu.
 3. Switch to the folder that will be the parent for the new project folder. Type the following command:
 cd <parent folder name>
 4. At the command prompt, type:
 compass create <the name of the project to be created>
Integrating Compass with PhpStorm
To develop a Compass-specific project in PhpStorm, you need to specify the Compass executable file compass and the project configuration file config.rb. You can do it either through the Compass Support page of the Settings dialog box or on the fly using an intention action that opens the Compass Support dialog box.
 1. Open the Compass page or dialog box by doing one of the following:
 - Open the Settings / Preferences Dialog by pressing Ctrl+Alt+S or by choosing File | Settings for Windows and Linux or PhpStorm | Preferences for macOS, and click Compass under Languages & Frameworks.
 1. In a .sass or .scss file, type the following import statement:
 @import 'compass'
 2. Click the red bulb icon or press Alt+Enter. Then choose Configure Compass from the suggestion list.
 The Compass Support dialog box opens.
 2. To activate Compass support, select the Enable Compass support checkbox.
 3. In the Compass executable file text box, specify the location of the compass executable file under the Ruby installation. Type the path manually, for example, C:\Ruby200-x64\bin\compass, or choose it from the drop-down list, or click Browse browseButton and choose the location of the compass file in the dialog box that opens.
 4. In the Config path field, specify the location of the project Compass configuration file config.rb. Type the path manually, for example, C:\my_projects\\compass_project\config.rb, or choose it from the drop-down list, or click Browse browseButton and choose the location of the compass file int he dialog box that opens.
 The Compass configuration file config.rb is generated during project set-up through compass create or compass init commands.
Creating a Compass Sass or a Compass SCSS compiler
Sass and SCSS are not processed by browsers that work with CSS code. Therefore to be executed, Sass or SCSS code has to be translated into CSS. This operation is referred to as compilation and the tools that perform it are called compilers.
PhpStorm integrates with a compiler that translates Sass and SCSS code from a Compass project without changing the Compass-specific project structure. To use the compiler in PhpStorm, you need to configure it as a File Watcher. For each supported compiler, PhpStorm provides a predefined File Watcher template. To run a compiler in your project, create a project-specific File Watcher based on the relevant template.
PhpStorm provides a common procedure and user interface for creating File Watchers of all types. The only difference is in the predefined templates you choose in each case.
 1. To start creating a File Watcher, open the Settings/Preferences dialog box by choosing File | Settings for Windows and Linux or PhpStorm | Preferences for macOS on the main menu, and then click File Watchers under the Tools node. The File Watchers page that opens, shows the list of File Watchers that are already configured in the project.
 2. Click the Add button new.png or press Alt+Insert and choose the compass sass or compass scss predefined template from the pop-up list.
 3. In the Program text box, specify the path to the executable file:
 - compass.bat for Windows
 - compass for Unix and macOS
 Type the path manually or click Browse browseButton.png and choose the file location in the dialog box that opens.
 4. In the Arguments text box, type one of the following depending on the operating system used:
 - For macOS:
 - compile $ProjectFileDir$ to process an entire directory
 - compile $ProjectFileDir$ $FilePath$ to process a single file
 - For Windows:
 - compile $UnixSeparators($ProjectFileDir$)$ to process an entire directory
 - compile $UnixSeparators($FilePath$)$ to process a single file
 - For Linux (Ubuntu):
 - compile $ProjectFileDir$ to process an entire directory
 - compile $ProjectFileDir$ $FilePath$ to process a single file
 5. Proceed as described on page Using File Watchers.
Running a Compass Sass or Compass SCSS compiler
When you open a Sass or SCSS file, PhpStorm checks whether an applicable file watcher is available in the current project. If such file watcher is configured but disabled, PhpStorm displays a pop-up window that informs you about the configured file watcher and suggests to enable it.
If an applicable file watcher is configured and enabled in the current project, PhpStorm starts it automatically upon the event specified in the New Watcher dialog.
 - If the Auto-save edited files to trigger the watcher checkbox is selected, the File Watcher is invoked as soon as any changes are made to the source code.
 - If the Auto-save edited files to trigger the watcher checkbox is cleared, the File Watcher is started upon save (File | Save All, Ctrl+S) or when you move focus from PhpStorm (upon frame deactivation).
PhpStorm creates a separate file with the generated output. The file has the name of the source Sass or SCSS file and the extension css. The location of the generated files is defined in the Output paths to refresh text box of the New Watcher dialog. However, in the Project Tree, they are shown under the source file which is now displayed as a node.

Beyond the aetiology debate: the "great LSD scandal" at Newhaven Private Hospital & the social foundations of mental health legislation in Victoria, Australia

This research presents a case for the extension of existing analyses of Australian psychiatric scandals beyond the conclusion that such events are an inherent feature of the profession by virtue of its failure to resolve the aetiology debate. A mid-century impasse in the aetiology debate – the continuous shifting over time of professional commitment between organic and environmental aetiologies of mental illness – has been identified as the catalyst for the emergence of the therapeutic paradigm of eclecticism that fostered the deep sleep therapy and 'Therapeutic Community' programs that were central to Australia's two infamous psychiatric scandals at Chelmsford and Townsville, respectively. While these two affairs were enduring the scrutiny of commissions of inquiry, the recommendations of which translated to the legislative reform of mental health services in the states of New South Wales and Queensland, a third such scandal was unfolding at Newhaven Private Hospital in Victoria involving the "injudicious use" of therapeutic LSD. By the late 1980s and early 90s, a number of former "patients" of Newhaven emerged claiming that they had never suffered any mental illness and that the LSD they had received had not been administered for therapeutic purposes but rather as a recruitment tool for a fringe religious sect known as The Family that had commandeered the hospital and the loyalty of a number of its staff. What constituted the scandal at Newhaven, however, was the fact that these activities continued unchallenged despite the implementation of statutory regulations – the Poisons (Hallucinogenic Drugs) Regulations 1967 – designed specifically to protect against the abuse of therapeutic hallucinogens. Having avoided any formal inquiry of its own, the Newhaven case represented not only a compelling narrative history opportunity, but also a test of the robustness of the prevailing argument that such scandals emerge as a consequence of the profession's failure to achieve consensus on the aetiology of mental illness against the implication that inadequate legislation facilitated the abuse. Using the case of Newhaven as a working example, this research analyses the historical mental health legislation of Victoria and parliamentary debates to construct a legislative history of the aetiology debate and confirm its role in the emergence of psychiatric scandal, arguing that the Poisons (Hallucinogenic Drugs) Regulations 1967, and indeed mental health policy more broadly, were in fact products of the debate. Furthermore, it demonstrates how, far from being insulated within the profession of psychiatry, the debate itself was informed by wider prevailing social, cultural, political and economic trends. The abuse of therapeutic LSD unfolded under permissive regulations which reflected the permissive nature of broader mental health policy embodied in the Mental Hygiene Acts and their signature initiative of deinstitutionalisation. This permissiveness was a symptom of the underlying atmosphere of eclecticism that characterised mid-century psychiatry in Victoria as it sought to accommodate simultaneously the biological and social bases for the eugenic and community-based measures, respectively, that developed in response to the co-emergent social forces of the 'mental hygiene' and 'anti-psychiatry' movements.

Imagine a future where buildings are smart enough to "talk" — at least to tell you when you are wasting precious natural resources and need to adjust temperature, water consumption, power or lighting. The Tulane University School of Architecture has teamed up with IBM to launch a pilot program to do just that, by uniting computer technology with green building practices.
Richardson Memorial Hall, the home of the School of Architecture, will be the first Tulane building to go online in the pilot program, officially called "Smart Building Solutions." Technology is being installed in the building now, with an eye toward a future renovation project.
"Richardson Memorial will undergo a major renovation starting in a few years," says architecture dean Kenneth Schwartz. "The challenge for us is to take a structure that's over 100 years old and make it smarter, more efficient and effective in the way it operates."
According to Schwartz, Tulane's opportunity to participate in the program came about thanks to Randall Dalia, an IBM executive who is an alumnus of the architecture school and the A. B. Freeman School of Business.
Two Tulane departments are involved in the project — technology services will oversee the computer programming and databases, while facilities services will manage the building. "We're operating under the mantra, 'If you can't measure it, you can't manage it,"' says Charlie McMahon, Tulane's chief technology officer. "We'll be able to collect data about usage and incorporate what we learn into the renovation project so we can have a more energy efficient building when we are done."
McMahon says that Richardson Memorial will serve as a "living laboratory" for the architecture faculty and students to see firsthand the impact of building energy management techniques into a historic structure. Says McMahon, "They'll learn about what works and doesn't work in energy management in an older building like Richardson."

bucket online refpage
Using the bucket object
The bucket object implements a bucket brigade device (in the electronics world, this is sometimes referred to as a discrete time-analogue delay line). As the examples below suggest, it's useful for single-sample delay lines, calculating averages, computing velocity and acceleration, and permutating lists by rotating them.
bucket Tutorials
In the Max tutorial on abstractions, you can find a classic example of why the bucket object is so useful - this Max tutorial demonstrates its use as a single sample delay for number values useful for constructing drawing commands.
bucket Tips and Workarounds
Velocity and Acceleration
Lots of people use the bucket object for shifting data in series, it's computationally useful for calculating first and second derivatives for streams of data. The terms "first and second derivative" are math-speak for keeping track of:
 - the rate that things are changing (that's what velocity (the first derivative) is - the rate of change in a value over time.
 - the rate of the rate that things are changing - that's what acceleration (the second derivative) is.
Here's a patch that does that:
-- Pasted Max Patch, click to expand. --
Running Averages
I also tend to use the object quite a bit in situations where I desire a running average over some finite set of events (if you want a running average for an stream or unspecified set of values, you'd use the mean object). Here's an example that calculates the average of the last 8 floating point input values:
-- Pasted Max Patch, click to expand. --
A Bucket for Symbols
The bucket object is a little unusual in that you don't need to worry about using arguments to the object in order to have it work with floating point values. In fact, bucket is so useful that people often ask whether or not there's a Max object that is similar but will work with symbols or lists. While there isn't a specific object, here's a Max patch that does exactly that (and it also helpfully outputs stuff in standard right-to-left order, too):
-- Pasted Max Patch, click to expand. --
Arbitrary List Rotation
One way to think of the bucket object is a as an object that adds new input values and rotates the list by one position. While you can rotate a list forward or backward using the r2l and l2r messages to the bucket object, performing arbitrary list rotations can be done using the zl object and specifying the rot option:
-- Pasted Max Patch, click to expand. --
Third-Party Max externals similar to the bucket object

The zl object (in its zl rot form). Useful for performing rotations of lists where the list offset is an odd number greater than 1.

Dead Children's Playground – Huntsville, Alabama - Atlas Obscura
Dead Children's Playground
Cemeteries can be boring for kids. The weight and import of death has not truly sunk in yet, so the cool headstones and elaborate grave markers must just seem like awesome rocks to play on, but no one will let them. They are going to live forever, so why is everyone so sad?
Well in a park space adjoining Alabama's Maple Hill Cemetery, the largest and oldest in the state, there is a small playground where they can have a place to release that energy. Of course this cemetery playground sees more ghost hunters and teenagers than bored children.
It seems like simple math that a sparse playground built on the grounds of a century-old cemetery would come to have a reputation more sinister than silly, but the planners put it in anyway.The small array of simple playground equipment includes swings, and a modern jungle gym. It is set in a low spot of the graveyard and surrounded by rocks and trees on three sides, making it all the more claustrophobic.
As the historic cemetery began running out of room in 2007, officials from the city of Huntsville decided to raze the play area to make room for more burials. Yet the locals were so outraged at the loss of their playground that a new playground was built, bringing the site back from the dead, so to speak.
Today the playground is known to locals as Dead Children's Playground and the mundane site has accumulated a deep catalogue of supernatural associations. As the believers would tell it, the swings can often be found to sway by themselves, spheres of cold ghost light can be seen floating around, and even the spectres of little kids have been spotted having a little midnight fun.
Dead Children's Playground, where kids can have the time of their afterlife.
Know Before You Go
The playground is located at the end of Newport Drive which is just off of McClung Ave SE. You can use Google Maps to map you there by typing in Dead Children's Playground. To access the park from inside the cemetery, you can park near section 40 and walk up the hill. You'll see a pavilion and the park is just the left of that.

BOEING'S SOLAR POWERED CLIMATE RESEARCH DRONE
Aurora Flight Science, a subsidiary of Boeing, specializes in unmanned Arial vehicles, is going to launch a solar powered autonomous aircraft, named Odysseus. The aircraft is designed to persistent flight at height-altitudes and will be used to perform climate and atmospheric research. it's first takeoff is scheduled in spring 2019.
According to Aurora, This aircraft operates like a cross between a drone and a satellite. It's intended to fly above weather and other aircraft and can cover a massive geographic area. It can fly continuously for months, because it's a solar powered aircraft.
It can gather data and can quickly communicate the information, It'll used to gather information related to environment, weather and storm monitoring. Aurora says it can be used for communication, connectivity and intelligence missions as well. It can also be reprogrammed mid-flight as tasks evolve.


Holmes' "Reasonable Man"
The concept of reasonableness that figures at the center of Holmes' notion of negligence is objective in nature, that is, conduct is measured against a community-wide standard of reasonableness rather that turn on the subjective mental state of the defendant. Recall that your text defines the reasonable man as "the man in the Clapham omnibus," or "the man who takes the magazines at home, and in the evening pushes the lawn mower in his shirt sleeves." Franklin & Rabin p. 51. Thus, a naive person who innocently lights firecrackers in a crowd not knowing that they might cause harm to others, will most likely be answerable in tort to those she injures because the community would deem that conduct unreasonable, even though we might also say that the conduct was reasonable in light of what she subjectively knew. In this case, she should have known of the danger her conduct posed to others.
But how realistic is an objective standard of reasonableness? Would all the members of a community agree about where to place the bounds of reasonable conduct? Might different populations feel differently? Is there any risk that the view ultimately determined to be reasonable is one which marginalizes the values of members of the society who typically experience marginalization?
If these concerns have any value, how should they affect the ways in which judges and/or juries determine the question of reasonableness in negligence cases? Should the care due from a defendant vary with the sex, race, ethnicity, religion etc. of the potential accident victim? Should the level of care due to a plaintiff vary with his or her sex, race, ethnicity, religion etc.?
After all, women are notoriously bad drivers and throwers, while men are much less nurturing than women (that was a joke, in case any of you are taking me seriously!).
The cases below are designed to illustrate more serious concerns about Holmes' Reasonable Man. As you read them, please consider both how you feel about a reasonable person standard being tailored to the particular circumstances raised in the cases, as well as the implications these concerns raise for negligence law more generally.

Hide All Examples
A Datomic entity provides a lazy, associative view of all the information that can be reached from a Datomic entity id.
The Entity interface provides associative access to
 - all the attribute/value pairs associated with an entity id E
 - all other entities reachable as values V from E
 - all other entities that can reach E through their values V
Nagivation to other entities is recursive, so with thoroughly connected data such a social network graph it may be possible to navigate an entire dataset starting with a single entity.
The Entity interface is completely generic, and can navigate any and all Datomic data.
The examples below refer to the following example datoms concerning entity 42, a.k.a. Jane Doe.
The Database.entity method will return an Entity, given an entity id or lookup ref:
jane = db.entity(42)
Given an entity, you can then navigate to any of that entity's attributes:
// returns "Jane"
firstName = jane.get(":person/firstName")
The special attribute :db/id provides access to the entity's own id:
// returns 42
id = jane.get(":db/id")
If an attribute points to another entity through a cardinality-one attribute, get will return another Entity instance:
address = jane.get(":person/address")
If an attributes points to another entity through a cardinality-many attribute, get will return a Set of entity instances. The following example returns all the entities that Jane likes:
// empty, given the example data
peopleJaneLikes = jane.get(":person/likes")
If you precede an attribute's local name with an underscore (_), get will navigate backwards, returning the Set of entities that point to the current entity. The following example returns all the entities who like Jane:
// returns set containing John
peopleWhoLikeJane = jane.get(":person/_likes")
Entities do not "exist" in any particular place; they are merely an associative view of all the datoms about some E at a point in time. If there are no facts currently available about an entity, Database.entity will return an empty entity, having only a :db/id.
Laziness and Caching
Entity attributes are accessed lazily as you request them. Once you access a particular attribute, the attribute will be cached for the lifetime of that entity instance.
The Entity.keySet method will return the keys available for an entity, without caching their values.
The Entity.touch method is a convenience that will access and cache all the attributes of an entity. In addition, touch will also access and cache the attributes of any other entities reachable through an attribute whose schema definition includes :isComponent true.
As an example, consider a database of orders, line items, and products. A line item is a component of an order. A product is related to an order, but is not a component of the order. In such a database, touching an order will access the order's attributes, and recursively access all the order's line items. Touching an order will not access the line items' products.
The touch method is a convenience, suitable for interactive exploration, or for when you know that you will need all of an entity's information. When this is not the case, it can be more efficient to be explicit, and ask for precisely what you need.
Note that none of the entity APIs mandate any communication with a server. Entities are lazy values, backed by a lazy database value in an application process. In particular, entities are not subject to the N+1 select problem, which is an artifact of client/server query architectures.
Entities and Time
Entities know the point in time on which they are based. Given an entity, you can access the database on which the entity is based
db = entity.db()
From the database you can then find the database's basisT, the transactions that contributed to the entity, etc.
Entities represent only a point in time, not the database across time. Notice that the "across time" aspect of the database vanishes when making entities.
The point-in-time nature of entities means that entities can be derived from any point-in-time view of a database, i.e. the return values of Connection.db, Database.asOf, Database.since, and Database.with.
Entities cannot be derived from with any time-spanning view of a database, i.e. the return value of Database.history.
Usage Considerations
Entities are always consistent.
Entities are lazy, immutable values. They are thread safe and do not require coordination with any other concurrent uses of the same information.
Entities are based on a point in time of the database. Navigation from an entity will always and only reach other entities with that same time basis, allowing extended calculations to be performed without coordination.
Entities are not a mapping layer between databases and application code. Entities are a direct, mechanical translation from database information to associative application access.
Entities are not suitable for existence tests, which should typically be performed via lookup of a unique identity.

The following example sorts the rows in the Continents table by the LowPoint column:
libname sql 'SAS-library';
proc sql;
title 'Continents, Sorted by Low Point';
select Name, LowPoint
from sql.continents
order by LowPoint;
Because three continents have a missing value in the LowPoint column, those continents
appear first in the output. Note that because the query does not specify a secondary sort,
rows that have the same value in the LowPoint column, such as the first three rows of
output, are not displayed in any particular order. In general, if you do not explicitly
specify a sort order, then PROC SQL output is not guaranteed to be in any particular
order.
Output 2.21 Sorting Columns That Contain Missing Values
Retrieving Rows That Satisfy a Condition
The WHERE clause enables you to retrieve only rows from a table that satisfy a
condition. WHERE clauses can contain any of the columns in a table, including columns
that are not selected.
Using a Simple WHERE Clause
The following example uses a WHERE clause to find all countries that are in the
continent of Europe and their populations:
libname sql 'SAS-library';
proc sql outobs=12;

French movie 'Cuties' fails as a social commentary, Netflix needs to take it down
The movie 'Cuties' (French: Mignonnes) is a 2020 French comedy-drama that showcases young girls, aged 11, engaging in acts and dance forms that hypersexualises them.
While the context of the movie tries to take a coming of age stance that shows a young girl grappling with personal challenges versus a changing digital culture and reclaiming her childhood at the end of the movie, it fails in its treatment of this context.
From the first few minutes of the movie it builds a world where young girls are shown to be engaging in sexual conversations and actions. These are not showcased as curious explorations that children at different ages may have but as actions that are serving the needs of the world around them.
Fifty eight minutes into the movie the lead child actress is shown twerking for two men who manage a facility the girls had entered without making the requisite payments, one of the men is shown to be checking the girl out and enjoying her actions.
The movie also makes us think about the number of child artists who have had to audition for these roles and the acts they have had to perform towards this selection.
While the intent behind the making of the movie may have been positive, the treatment of the movie making process, the final scenes that the audience views, as well as the basic content of the movie itself places children in an unsafe sexualised environment and subjects the artists of the movie to possible consumption of the movie in an unsafe manner.
The filmmakers and Netflix have stated that the intent of the movie was to throw light on and criticize the hypersexualisation of young children, especially young girls. However, the lens through which the movie is made is often predatory and does not adequately relay this critique to the audience.
There are multiple petitions on that are urging Netflix to take the movie off its platform. We are urging to combine the power of these petitions to get Netflix to take action and remove the movie from its platform. You can add your voice to this movement by signing one of the petitions.

text:
primary property of cognitive workload. It refers to a measurement's ability to detect different degrees of workload imposed by the task or system. The degree of sensitivity required is directly associated with the question to be answered by the workload technique. Two basic questions asked with regards to workload are: (1) is an overload occurring which demonstrates a degradation in operator performance, and (2) is there a potential for such an overload to exist.
Diagnosticity refers to the ability to discriminate differences in specific resource expenditures, as related to the multiple resources model. For example, a secondary tracking task may demonstrate there is an overload for motor output when an operator is performing a typing task.
Global sensitivity refers to a measurement's capability to detect changes in workload without clearly defining why the change is occurring in workload. A globally sensitive measure cannot discriminate differences in specific resource expenditures.
Intrusiveness is a measurement's ability to interfere with the primary task. An intrusive task may not affect performance (an operator who is not overloaded may compensate) but it may affect the workload measure (an operator may have felt more workload, heart rate may have increased, etc.). In an operational environment, this property is extremely important to control, otherwise, operator performance may decrease and operator workload may increase due to the chosen workload measurement technique and not to changes in the task.
Implementation requirements include any equipment, instruments, and software that are necessary to present the task. It also includes data collection procedures and any operator training that is necessary for proper use of the measurement.
Operator acceptance is important to ensure that a measurement will reflect accurate data. If an operator does not accept the measurement, the measurement could be ignored (e.g., the operator ignores the secondary task or randomly rates the task with a subjective measurement), the operator could perform at a substandard level, or operator workload could increase due to the measurement not due to the task.
Transferability is the ability of a measurement to be utilized in a variety of applications. Transferability is based on the specific measurement and task or system to be measured. For example, a tracking task (i.e. one where a specific user action is monitored) may be transferable, but only to a system that will be measured with a secondary task, which focuses on visual, spatial, and manual skills.
For the service representative embodiment of the present invention, the cognitive workload (mental workload) method 18 is chosen because of its ability to obtain a variety of information. However, any categorization method used would still be within the spirit and scope of the present invention. Cognitive workload has been described in several publications. Two examples are O'Donnell, R. D., and Eggemeier, F. T. (1986). Workload assessment methodology, and K. R. Boff, L. Kaufman, and J. Thomas (Eds.), Handbook of perception and human performance: Volume II. Cognitive processes and performance (pp. 42/1-42/49). New York: Wiley.
Different types of cognitive workload techniques are shown in
For subjective measures, users are required to judge and report the level of workload experienced during the performance of a specific task or system. These measures are usually based on rating scales. Theoretically, the operator can accurately report an increase in effort or capacity expenditure associated with subjective feelings. Some of the more researched subjective assessment techniques include the Modified Cooper-Harper, Subjective Workload Assessment Technique (SWAT), NASA-Task. Load Index (NASA-TLX), and Subjective Workload Dominance (SWORD).
A reason for using subjective measures is that they typically are highly sensitive to detecting overloads. They tend to be globally sensitive and are not intrusive since they are performed after the task is completed. In addition, the implementation requirements are low (e.g., a pencil and paper, possibly some training on the measurement) and operator acceptance is usually high. However, subjective measures are not always diagnostic, especially in facilitating the redesign of a task or system. The few subjective techniques that have some diagnostic abilities are very generalized. Some subjective techniques also have problems with operator acceptance.
Physiological measures examine the physiological response to the task requirements. Typically, users who experience cognitive workload, display changes in a variety of physiological functions. Some of the physiological measurements of workload include heart rate, heart rate variability, sinus arrhythmia, EEGs, ERPs, and eye blink.
Physiological measures tend to be extremely sensitive, some are highly diagnostic, while others are globally sensitive. However, physiological measures are intrusive, have a high degree of implementation requirements (e.g., for an EEG, an EEG machine, an oscilloscope, and electrodes are needed), and are expected to have low operator acceptance in operational environments.
Performance-based measures are broken down into primary task measures and secondary task measures. Primary task measures evaluate aspects of the operator's ability to perform the intended task. Typically, all measures of cognitive workload should include the primary task performed by the operator. Primary tasks are only sensitive to overloads in workload, they are not typically sensitive to the potential for an overload to exist. Some primary tasks are globally sensitive. Since they are the primary task, they are not intrusive and have high operator acceptance. However, primary tasks are not diagnostic, and are generally not transferable. Their implementation requirements vary.
Secondary task measures are categorized as either a subsidiary task paradigm or a loading task paradigm. In the subsidiary task paradigm, secondary task measurements evaluate how much of one or more resources are being consumed by the primary task. Users put emphasis on primary task performance. Secondary tasks are added to the primary task to impose an additional load on the operator. Analyzing performance decrements on secondary tasks determines how much resources are consumed. Properly choosing secondary tasks determines which resources are consumed.
In the loading task paradigm, secondary task measurements determine when and how much the primary task deteriorates. Users put emphasis on secondary task performance while the degree of difficulty of the primary task is manipulated. Two or more primary tasks may also be compared for task deterioration with this paradigm.
Secondary tasks are extremely diagnostic and may be sensitive to potential overloads. However, if a secondary task is chosen which is not employing the same resources that the primary task is, employing the secondary task will not be sensitive to changes in workload and may not display expected overloads. It is usually recommended that a battery of secondary tasks be used and this can be time consuming. Secondary tasks are, by nature, intrusive, tend to have high implementation requirements (e.g., for a tracking task, a joystick, screen, and computer are needed), and are expected to have low operator acceptance in operational environments.
For the service representative embodiment, a subjective measure is chosen. As shown in
The NASA-TLX evolved from the NASA Bipolar scale. Similar to SWAT, the Bipolar scale was developed with the consideration that workload is multidimensional, thus, a measurement of workload should also be multidimensional. Developed after SWAT, the Bipolar was designed with nine scales because the Bipolar authors did not believe the scales in SWAT were sufficient. The Bipolar also recognizes that from task to task, the scales may vary in importance, and allows users to acknowledge these differences. In addition, this technique was developed to contain diagnostic scales, which could be rated based on subjective importance.
The NASA-TLX inherited properties from the Bipolar scale with the exception that the NASA-TLX has six scales to allow for an easier implementation. The scales represent task characteristics (mental demand, physical demand, and temporal demand), behavioral characteristics (performance and effort), and operator's individual characteristics (frustration). These scales and their corresponding definitions are shown in
TLX also added the ability to consider individual differences through the weighting of the workload scales. TLX involves a two-part procedure consisting of both ratings and weightings. After the operator completes the task, numerical ratings are obtained for each of the six scales. The operator is given both the rating scale definition sheet and a rating sheet. On the rating sheet, there are twenty intervals with endpoint anchors for each of the six scales. Users mark the desired location for each scale. A score from 5 to 100 is obtained on each scale by multiplying the rated value by five. Depending on the situation, rating sheets, verbal responses, or a computerized version are considered practical.
In the second part of TLX, users weigh the six scales. Paired comparison procedures are implemented for 15 comparisons, accounting for comparisons between all of the scales. Users choose the scale which most significantly created the level of workload experienced in performing a specific task. For each task and operator, each scale is tallied for the number of times it was chosen in the paired comparisons. Scales can have a tallied value between zero and five. Each new task requires users to rate and weigh the scales upon its completion.
The ratings of each scale are arranged in a raw ratings column. Adjusted ratings are calculated by multiplying the raw ratings by the corresponding tallied scale scores. The adjusted ratings for all six different scales are then summed. The total sum is divided by 15 (for the number of paired comparisons) to obtain the weighted workload score (ranging from 0 to 100) for the operator in that task condition. Analysis of the data can then be performed.
Due to the multidimensional properties of workload, some level of diagnosticity may be distinguished by using TLX. Generalized conclusions may be made based on operator strategies and on weightings and judgments of the six dimensions of mental demand, physical demand, temporal demand, performance, effort, and frustration.
TLX is not considered intrusive because it is performed after the task is completed. Implementation requirements are typically low; the definition sheet, rating sheet, and paired comparisons are needed for every operator and task. Some time may be required for users to practice with and familiarize themselves with the scales. Operator acceptance is

As a vegetarian or vegan, it is difficult to find food at Italian restaurants often. If you are lusting for vegetarian food in Chilliwack, head over to Pallioti's Italian Restaurants in Chilliwack, Maple Ridge, and Abbotsford. Visit our website to check out our lunch and dinner menus at Pallioti's.
Why is it tough to find vegetarian Italian food?
If you traveled to Italy or tried to cook Italian food, you would generally have a harder time finding vegetarian-friendly ingredients. Some of the most signature dishes incorporate meat as an essential ingredient. For example, a classic carbonara is not carbonara without the pancetta.
Also, most Italians would scoff at the idea of using 'vegetarian' ingredients for such a classic dish! Another traditional dish, like lasagna, also relies on meat as the main ingredient.
Fortunately, it does not mean you can't find any vegetarian food at all. For example, a lot of appetizers like bruschetta can use vegetarian ingredients, while still being authentic. You can also find pasta arrabbiata, which only uses vegetables.
Classic vegetarian dishes to order at Italian restaurants
As we mentioned, authentic Italian cuisine is not entirely hostile to vegetarians. There are a few native Italian dishes that are also vegetarian. The most famous vegetarian dish is probably Pasta Arrabiata, whose main ingredients are garlic, tomato, and some chili. Another notable Italian American dish is Pasta Prima Vera, which uses loads of vegetables like broccoli and bell peppers.
Spaghetti Aglio is another classic vegetarian dish hailing straight from Italy. It merely uses garlic, olive oil, and some chili for seasoning. Spaghetti al Pomodoro is also a vegetarian-friendly dish from Italy. It uses sun-ripe tomatoes, garlic, and basil.
Vegetarian food for lunch
At our restaurant, you will find several vegetarian dishes like Pasta Prima Vera and bruschetta. We also have vegetarian-friendly Margherita pizzettas. For delicious and fresh vegetarian food in Chilliwack, visit our restaurant in Chilliwack.
In our lunch menu in Chilliwack, we have the vegetarian-friendly breaded mozzarella and bruschetta crostini for an appetizer. Then comes the pasta primavera and curried vegetables pasta for the main course. In addition, you could also order a fresh rocket salad, tossed salad, or a Caesar salad on the side.
Vegetarian food we offer for dinner
Again in our dinner menu, we have the breaded mozzarella and bruschetta crostini as appetizers. You could also order a minestrone that is full of vegetables. For vegetarian-friendly salads, all of our salads are vegetarian. This includes Caesar, Italian, Roman, Tuscan, tossed, and rocket salads. You will find fresh ingredients like tomatoes, feta, olives, arugula, basil, and cucumbers.
Our vegetarian main dishes include the Four Cheese Tortellini, the Portobello Ravioli, Fettucine Al Prima Vera, and Curried Vegetable Tortellini. You can also order the Margherita pizzetta, which is vegetarian. We only use the freshest ingredients for these dishes, with fresh tomato sauce, basil, and fragrant garlic.

How many calories do you burn skateboarding?
A lot has been said and discussed about shedding excess weight. Routine workout, is however, considered the best and most ideal way to keep your body fit. Swimming, riding a bicycle, and weight lifting can help you lose calories not only fast but in an effective way.
Skateboarding, on the other hand, is a good workout activity many did not know canhelp to improve your agility, flexibility, and balance.Away from that, the main focus here is to know the number of calories you can losewhen skateboarding: – An in-depth study to understand all you need to know aboutburning calories.
Understanding calories.
Calorie (usually denoted cal) is a unit of energy. Different foods provide different levels of calories. Macronutrients are what provide energy from food.
How many calories can one burn in an hour?
You can burn around 396 – 406 calories after an hour of skateboarding. However, it all depends on a few factors; Age, weight, and the intensity of workout play a significant role in the number of calories you can burn.
Transition skateboarding can help you burn over 769kcal an hour. But, you need to understand that over-exercising can not only cause fatigue, but it can lead to injuries and decreased performance.
When skateboarding, you are no different from a person who is working out in the gym or playing football. As a skateboarding enthusiast, you work out every single part of the body. From the toes muscles to the muscles around your arms, you would not notice quickly.
Relationship between calorie, fat, and skateboarding.
Each gram of fat is equal to 9 calories. When you have ingested more calories than what the body needs, it is converted and stored as fat. Excess fat, on the other hand, is not good. Studies show that the consumption of fatty acids in the body without exercise can expose you to risks like cardiovascular disease.
So how does skateboarding help?
To lose the excess fat, you need to go for skateboarding regularly. Depending on your weight and age, the fatty acids in your body will reduce immensely.
Below is an explanation of how to calculate the number of calories you can lose when doing exercise.
Different activities can be measured by their "MET Values." These values determine the average and overall amount of energy required.
When you multiply the MET (Metabolic equivalents) value by your weight in kilograms, you will know the number of calories burnt.
Example: If you sit quietly for an hour, a 60kg person will burn 60 calories (kcal). If he does an activity that has a MET value of 2, he will burn 120 calories.
To know the different MET values of various activities, you should visit the compendium of physical activity (A physical activity website) to understand the codes and values of different activities.
The calories burnt skateboarding calculator is one platform that calculates the number of calories burnt
Importance of skateboarding.
Skateboarding can not only make you lose the much-needed calories. You gain muscle and mental strength.
