An Unsolicited Plan for a Mullins Creek Greenway
I wrote an earlier piece on how UA needed to take a page out of UALR's book and create a Mullins Creek Greenway, similar to UALR's Coleman Creek Greenway, but I didn't include many specifics. So here is my plan for Mullins Creek in greater detail:
Overall Objectives:
1. Provide the campus community a scenic and safe trail that connects housing areas, athletic facilities, classrooms, and shopping areas.
2. Improve the habitat and water quality of Mullins Creek.
3. Provide a viable alternative to driving around campus that is healthier, more scenic, and just as fast.
Stage 1: The Cheap Stuff
1. Establish a "no-mow" zone around the creek. This would actually be more of a mow twice a year zone that would immediately help decrease erosion along the creek, improve water quality and provide habitat for wildlife.
2. To avoid looking like an overgrown drainage ditch, attractive native grasses, shrubs and trees could be planted along the banks for little extra cost. Inland sea oats, soft rush, blackgum, red bud, sycamore, and dogwoods are just a few examples of attractive plants that would improve aesthetics, water quality, and habitat. Streambank and wetland plants can typically be purchases for ~$1 a plug. Tree prices vary depending on size, but can be as cheap as $30 for a 6' tall tree. Smaller sapplings go for 10 cents when bought in bulk. If done as part of an official mitigation plan, this project might even pay for itself.
Stage 2: The Not Cheap, but Not Really That Expensive Stuff
1. Increase the width of existing trails/sidewalks to at least 12 feet.
2. Move existing sidewalks that are within 10 feet of the creek (red on the map) farther away. Placing a path too close to the creek can, and has, led to bank erosion, flooded trails, and expensive repairs.
3. Pave new sections of trail to connect existing sections each other and dorms, apartments, athletic facilities, classrooms, and shopping areas.
Stage 3: The Expensive Stuff.
1. Remove the parking lot at MLK and Razorback Rd. Replace it with a 3-4 story parking deck located away from the creek that has 1/3 the footprint (shown in red and green below).
2. Convert the old parking area nearest the creek to a Trail of Tears Park with educational signage.
3. Build a pedestrian bridge over MLK. This street is really busy and waiting to cross it can be a pain.
4. Perform a coordinated, natural channel design, stream restoration of the creek where it is above ground on campus. This will save money on maintenance in the long-run and improve water quality and habitat on campus and downstream.
Here is a map of the proposed trail. The majority of this is already in place. Existing sections would just need to be improved and short connections would need to be made.
Rock Island Bridge Opens at Clinton Library
The River Trail just got one step closer to being complete. You can now bike over the Rock Island Bridge at the Clinton Library instead of having to carry your bike up/down steps on the junction bridge or vie with traffic on other downtown bridges.
Next (and last?) step, do something about the crappy section between downtown and Riverdale. You can't really call it a trail if you all you have is bike lanes on busy streets.

UA needs to Copy UALR - Mullins Creek vs. Coleman Creek
Mullins Creek on the University of Arkansas campus in Fayetteville has a lot in common with Coleman Creek which flows through UALR's campus in Little Rock. Both creeks:
1. Flow through campus and were historically treated more as obstacles than amenities.
2. Had buildings built OVER them.
3. Were crossed by the Trail of Tears. (and at what is now the southern end of each campus even!)
4. Face problems associated with rapid urban development of their watersheds. (trash, erosion)
5. Are impacted by Razorback football game tailgating. (War Memorial Park in Little Rock, Razorback Gardens in Fayetteville.)
With all they have in common, their recent history couldn't be more different.
1. Formed the Coleman Creek Greenway Committee with experts in landscape architecture, environmental engineering, ecology, GIS, habitat restoration, trails, etc.
2. Came up with plans to improve the creek's habitat and water quality.
3. Developed plans for a wide, paved, bike and pedestrian trail that will eventually run along both sides of the creek and connect the campus to surrounding neighborhoods and city parks.
4. Tore down multiple buildings and ripped up acres of parking to build Trail of Tears Park, which has educational signage and native plant landscaping along the first section of the trail to be completed.
5. Is working to decrease vehicular traffic through campus and boost bike and pedestrian traffic.
1. Threw some boulders in the creek, which actually sped erosion, and called it a day.
(I don't know if this is completely fair, since I haven't been in Fayetteville for very long. I've read that plans for a restoration are being drawn up but haven't seen any evidence of plans or intent to implement them. UA did remove buildings where Razorback Gardens and the baseball field are, but I think this was done more for sports than the creek.)
UA needs to form a Mullins Creek Greenway Committee with the full backing of the Chancellor. The goals of this committee need to be to:
1. Boost student access to, and appreciation of, Mullins Creek.
2. Improve water quality in Mullins Creek.
3. Improve habitat and the aesthetics of the creek.
4. Find ways to better link the creek and campus to the surrounding community.
Here are some basic ways some of these goals could be accomplished:
1. Conduct a natural stream channel restoration of the sections of the creek that are still above ground. As part of this, plant the banks with native grasses, shrubs, and trees and limit mowing of a 25' buffer along the creek to once or twice a year.
2. Expand and improve the sidewalks along and near the trail. Take the trail to the southern end of campus and connect it to the Tsa La Gi Trail and Hill Place Apartments.
3. Create a Trail of Tears Park at the southern edge of campus that educates people on the history of the Trail of Tears. Make sure this park is connected to the main trail along the creek.
4. In the long run, seek to remove impervious surfaces on campus. Install green roofs, rain gardens, and bioswales. Store rainwater in cisterns and use that for irrigation on campus.

Lake Wedington Loop #1
Today, my friend Jess and I decided to take advantage of the great weather and go on a bike ride (see map below). Neither of us are avid cyclists, but we like to pretend we are in great shape and can do pretty much anything (yes this attitude has gotten us into some trouble in the past).
After packing swimsuits and a frisbee (neither of which ended up being used), we struck out for Lake Wedington without really doing much research. It turns out the lake is 17 miles west of town and that you if you take the seemingly logical choice of Wedington Dr. to get there, you have some pretty nasty hills in the way. We added an unnecessary hill, by initially deciding to take MLK west and then quickly deciding that road was too nasty and deciding to head north to Wedington Dr.
Wedington Dr. is a large road with little shade for most of the way. In the more developed areas, it does have a sidewalk and in places a nice wide bike path. After about 8 miles, the large relatively flat road begins to curve up and down some hills. A couple of the downhill sections were so great (long and steep) that we decided to find a different way home.
We arrived at the lake around 5:00 having taken a little over 1.5 hrs to get out there. At this point we admitted to ourselves that we were already pretty pooped and probably didn't have the time or energy to swim or throw a frisbee given that sunset is around 7:00 these days. So after exploring the cabins, lodge, swimming area, and campground we headed back towards Fayetteville.
This time, we took a very different route and it ended up being a lot better and also worse in places. The southern section of the loop shown on the map is much flatter, and for most of the way it is more scenic and less busy. All that comes to a nasty, screeching halt when you reach Main St./MLK Blvd. There is a bike lane for a bit in Farmington, and then ironically, around the time you see the "Fayetteville: Bike Friendly City" sign, there is no bike lane and no decent sidewalk. Needless to say, the last five miles on MLK were not fun. If you live in the northern part of Fayetteville, you might change the route a bit and take Double Springs Rd. or Broyles St. north back to Wedington Dr. for the final leg back


of the Navigation example app on GitHub.
You can set a LanguageCode to localize the notification text and a UnitSystem to decide on metric or imperial length units. Make sure to call this before a route is set, as otherwise default settings (en-US, metric) will be used:
private func setupVoiceGuidance() {
 let ttsLanguageCode = getLanguageCodeForDevice(supportedVoiceSkins: VisualNavigator.availableLanguagesForManeuverNotifications())
 visualNavigator.maneuverNotificationOptions = ManeuverNotificationOptions(language: ttsLanguageCode,
 unitSystem: UnitSystem.metric)
 // Set language to our TextToSpeech engine.
 let locale = LanguageCodeConverter.getLocale(languageCode: ttsLanguageCode)
 if voiceAssistant.setLanguage(locale: locale) {
 print("TextToSpeech engine uses this language: \(locale)")
 } else {
 print("TextToSpeech engine does not support this language: \(locale)")
 }
}
For this example, we take the device's preferred language settings. One possible way to get these is shown below:
private func getLanguageCodeForDevice(supportedVoiceSkins: [heresdk.LanguageCode]) -> LanguageCode {
 // 1. Determine if preferred device language is supported by our TextToSpeech engine.
 let identifierForCurrenDevice = Locale.preferredLanguages.first!
 var localeForCurrenDevice = Locale(identifier: identifierForCurrenDevice)
 if !voiceAssistant.isLanguageAvailable(identifier: identifierForCurrenDevice) {
 print("TextToSpeech engine does not support: \(identifierForCurrenDevice), falling back to en-US.")
 localeForCurrenDevice = Locale(identifier: "en-US")
 }
 // 2. Determine supported voice skins from HERE SDK.
 var languageCodeForCurrenDevice = LanguageCodeConverter.getLanguageCode(locale: localeForCurrenDevice)
 if !supportedVoiceSkins.contains(languageCodeForCurrenDevice) {
 print("No voice skins available for \(languageCodeForCurrenDevice), falling back to enUs.")
 languageCodeForCurrenDevice = LanguageCode.enUs
 }
 return languageCodeForCurrenDevice
}
Note that the HERE SDK supports 37 languages. You can query the languages from the VisualNavigator with VisualNavigator.availableLanguagesForManeuverNotifications(). All languages within the HERE SDK are specified as LanguageCode enum. To convert this to a Locale instance, you can use a LanguageCodeConverter. This is an open source utility class you find as part of the Navigation example app on GitHub.
Each of the supported languages to generate maneuver notifications is stored as a voice skin inside the HERE SDK framework. Unzip the framework and look for the folder voice_assets. You can manually remove assets you are not interested in to decrease the size of the HERE SDK package.
However, in order to feed the maneuver notification into a TTS engine, you also need to ensure that your preferred language is supported by the TTS engine. Usually each device comes with some preinstalled languages, but not all languages may be present initially.

Stop Navigation
While turn-by-turn navigation automatically starts when a route is set and the LocationPrivider is started, stopping navigation depends on the possible scenario:
Either, you want to stop navigation and switch to tracking mode (see below) to receive map-matched locations while still following a path - or you want to stop navigation without going back to tracking mode. For the first case, you only need to set the current route to nil. This will only stop propagating all turn-by-turn navigation related events, but keep the ones alive to receive map-matched location updates and, for example, speed warning information. Note that propagation of turn-by-turn navigation events is automatically stopped when reaching the desired destination. Once you set a route again, all turn-by-turn navigation related events will be propagated again.
If you want to stop navigation without going back to tracking mode - for example, to get only un-map-matched location updates directly from a location provider - it is good practice to stop getting all events from the VisualNavigator. For this you should set all delegates individually to nil.
You can reuse your location provider implementation to consume location updates in your app. With HERE positioning you can set multiple LocationUpdateDelegate instances.
Tracking
While you can use the VisualNavigator class to start and stop turn-by-turn navigation, it is also possible to switch to a tracking mode that does not require a route to follow. This mode is also often referred to as the driver's assistance mode. It is available for car and truck transport modes.
To enable tracking, all you need is to call:
visualNavigator.route = nil
locationProvider.enableDevicePositioning()
Here we enable getting real GPS locations, but you could also play back locations from any route using the LocationSimulator (as shown above).
Of course, it is possible to initialize the VisualNavigator without setting a route instance - if you are only interested in tracking mode you don't need to set the route explicitly to nil. Note that in tracking mode you only get events for the NavigableLocationDelegate. All other delegates will simply not deliver events when a route is not set. This enables you to keep your delegates alive and to switch between free tracking and turn-by-turn-navigation on the fly.
Tracking can be useful, when drivers already know the directions to take, but would like to get additional information such as the current street name or any speed limits along the trip.

TR121 Nursery visits for Fiji kava farmers
Three farmer groups in Fiji were selected for study tours of established nurseries around Viti Levu. This report highlights the observations of and lessons learned by the groups that received training and advice on the basics of establishing and managing a nursery, soil sterilisation and grafting. The report also includes accounts of the progress made by the groups in establishing nurseries in their villages.
The idea behind the establishment of the nurseries was that farmers should not only focus on kava as a source of income but that they should also include fruit trees and vegetables that can be included in the family diets and also supplement family income. This report concludes that the concept of establishing and managing nurseries should be expanded to the other 11 provinces in Fiji to create a green revolution in agriculture.

Makaryev Fair (Russian: Макарьевская ярмарка) was a fair in Russia held annually every July near Makaryev Monastery on the left bank of the Volga River from the mid-16th century to 1816. Following a massive fire in 1816, it was moved to Nizhny Novgorod, but for some decades thereafter it still was commonly referred to as Makariev Fair. It attracted many foreign merchants from India, Iran, and Central Asia.
This fair was a commerce centre to sell up to half the total production of export goods in Russia. The fair ceased in 1929. A society named Nizhegorodskaya yarmarka (Russian: Нижегородская ярмарка, Nizhny Novgorod fair) was created in 1991 with its headquarters in the former main fair building. However, today it is not actually a fair, but an exhibition center.

The Cherenkov effect is a well-known phenomenon and its properties are widely used in many fields of physics. However, some features of the polarization characteristics of Cherenkov radiation that appears when charged particles pass near azimuthally asymmetric, finite dielectric targets are still poorly studied. This problem is solved in this work. The polarization characteristics of Cherenkov radiation in the case of a rectangular dielectric screen are analyzed using the Stokes approach. Owing to the azimuthal asymmetry of the target, radiation acquires an elliptic polarization whose rotation direction and inclination angle depend both on the direction of radiation propagation and on the dielectric properties of a substance. The results demonstrate that the Cherenkov effect can be used to create sources of elliptically polarized radiation with the controlled direction of polarization rotation.

The objective of this study was to design and develop a prototype twin vacuum disk metering unit so that seeding can be achieved at higher forward speeds while reducing the peripheral speed of the vacuum disk for improved seed spacing uniformity performance and increased field work capacity. In order to meet this objective, a new precision seeding unit with twin vacuum disks, each being a mirrored view of the other and geometrically the same, was designed in animated drafting software and then it was manufactured and used for the laboratory experiments. Three crop seeds were used to determine the performance of the new metering unit in the lab on a sticky belt test stand. Two alternative measures were used to quantify the seed spacing accuracy, and polynomial functions using the principles of response surface methodology were developed to calculate the optimum level of the variables. The tests performed in the laboratory at 2, 3, and 4 ms-1 forward speeds resulted in improved seed spacing accuracy values, while the quality of feed index measure went down once the forward speed increased from 2 to 4 ms-1. The quality of feed index with the new metering unit was obtained to be 100% at 2 ms-1, while it was almost 98% for all crop seeds at 3 ms-1. The forward speed of 4 ms-1 resulted in quality of feed index values of 92%, 96%, and 96% for cotton, sunflower, and corn seeds, respectively.

text: Although the measured amount of roof deformation associated with a given rollover crash test is often the residual or post test deformation, rollover crash test researchers are aware that roof deformation occurs dynamically throughout the rollover event with varying magnitude. The challenge to quantifying dynamic roof deformation has been the lack of a reliable method to measure and record the dynamic roof deformation during the rollover test. Researchers have explored various methods to measure dynamic roof deformation including the use of film analysis of external targets, accelerometers, string potentiometers, and 3D photogrammetry.This paper discusses a series of simulated curb trip rollover tests conducted to study and compare different methodologies to measure and record dynamic roof deformation. The tests involved midsize crossover utility vehicles instrumented with accelerometers on the roof rails at the A and B pillars and string potentiometer arrays at roof locations above the front driver and passenger seating locations. High speed digital motion cameras were rigidly mounted inside the vehicles to monitor the movement of the interior roof targets as the roof deformed during the rollover event. This paper discusses and compares the dynamic roof deformation data as measured by the roof string potentiometers and 3D photogrammetry as compared to post-test residual deformation measurements.

Can u believe that your credit card is capable of diagnosing HIV at a cost of just $1? It's true, a portable blood test can be performed and the presence of HIV can be instantly indicated by mChip device designed by the scientists of the University of Columbia in New York. mChip is the device on the size of a credit card specially designed for this purpose. Various tests conducted among various majorities of people revels that the test has a perfect 95 % accuracy on an average. The cost is cheaper hence a large set of diagnostic tests is possible and is accessible even for common people. It makes a large difference in the mentality of people who hesitate to go to clinics or hospitals for testing their blood. A pin-prick of blood is taken and optics is used to read the fluid.
The blood passes through ten detection zones for analysis and returns a positive or negative outcome for HIV or syphilis. The time duration taken is about 15 minutes. A simple color-code similar to pregnancy test is used to display the result. mChip extremely cheap and efficient and serves as a major breakthrough in fighting against HIV throughout the world.

How to Get Mold Smell Out of Dresser Drawers
Mel Frank
Dressers are a perfect way to store clothing, keeping it safely out of sight yet on hand and quickly accessible. The problem is that these drawers are dark, typically sealed off when closed, and can quickly develop moisture that leads to the development of a musty, moldy odor. To remove the odor, simply treat the drawers with a quick odor removal solution.
Get rid of mold smell with ease.
 1. Place a small dish of baking soda in each drawer. The baking soda is a natural odor absorbant that will also draw any moisture out of the drawers. Let the baking soda sit overnight.
 2. Fill a spray bottle with white vinegar. The vinegar is a deodorizing agent and will also kill any mold or mildew growth that is causing the odor.
 3. Spray the vinegar solution into all of the drawers.
 4. Keep the drawers open, and allow the drawers to air out overnight.
 5. Repeat if needed if all odor has not dissipated.

Introduction: OBD2 Ultra Slim Extender Mod
This project was born for a simple reason: use a obd2 bluetooth adapter without removing the OBD\fuse cover of my Hyundai Ioniq (in my case). As showed in the picture, with this extender you can keep the ELM237 and the extender inside the fuse box, so when the cover is closed everything is out of view. And now, without further ado, let's start!
Step 1: What Do You Need
MATERIALS:
-OBD extender, I got from Amazon 7,50€ _URL_
- compatible OBD2 bluetooth adapter like ELM237 2,59€ from Aliexpress _URL_
- at least 5 flat pins
- super glue (OPTIONAL epoxy glue)
TOOLS
- weldering iron + tin
- 3D Printer + ABS filament.
- multimeter.
- tweezers and cutter.
Step 2: Procedure
1- Download and print the ultrathin connector from my thingiverse page _URL_
I suggest to print it using ABS filament, in the car the temperature may reach 70°C and PLA could melt.
2- Cut the extender near the male OBD2 connector and remove the sheath, you need to keep the wires of pins 4, 5, 6, 14, 16 and remove the others. Use a multimeter to find the right wires.
If you have the same extender as I do check the photo for colour and position.
NOTE: pin 4 and 5 are shorted (they are both GND).
3- Bend the flat pins 90° and weld the wires.
4- To keep the pins in position connect them into the other side of cable (the female connector) and use a little bit of epoxy glue; alternatively you can close the connector using super glue but in this second way the pins will be not very stable, so pay more attention when attaching the connector in the car.
Step 3: Power ON-OFF OBD2
Seems that in my car (hyundai Ioniq) the obd port is always powered, so it can drain the battery of your car if left for a long period. You can buy the extender with an on-off button like this one _URL_

One of the most important tools a family lawyer can use in a divorce case is a lifestyle analysis: the process of tabulating and analyzing the income and expenses of the parties in order to confirm or refute a spouse's income claims, among other uses. This updated edition of Lifestyle Analysis in Divorce Cases: Investigating Spending and Finding Hidden Income and Assets discusses these subjects in logical, easy-to-understand manner, bringing clarity to a topic that could be confusing for attorneys and judges who often lack an accounting or finance background.
A financial expert or forensic accountant can play an integral part in a divorce case involving complex financial matters. One of the most important tools they can use is a lifestyle analysis, a component being employed in an increasing number of divorces.
Lifestyle Analysis in Divorce Cases walks through the critical documents used in the lifestyle analysis, as well as the process used to complete a thorough and accurate analysis. The book discusses in detail the information that can be gleaned from tax returns, financial statements, bank statements, and other financial documents. The lifestyle analysis is then used to determine the standard of living for all parties, which will influence important support calculations and may affect property division. Additionally, a lifestyle analysis can uncover hidden sources of income and be used to evaluate the finances of each party in a prenuptial agreement.
Author Tracy Coenen, CPA, CFF, discusses these subjects in a manner that is logical and easy to understand, bringing clarity to a topic that could be confusing for attorneys, judges, and juries who often lack an accounting or finance background. The book begins with the critical factors to use in analyzing a couple's standard of living, followed by a discussion of the various types of income and why they should be either included or excluded from calculations in a family law case.
To help an attorney determine whether a lifestyle analysis is necessary for a particular case, the author discusses the numerous red flags that may indicate hidden income or assets or other financial irregularities, including sources for obtaining information, the documents needed for a lifestyle analysis and a strategy for gathering and managing these documents, and discovery from the perspective of the financial expert. Additional chapters focus on key elements included in a lifestyle analysis, including:
- Analyzing historical spending
- Locating hidden assets
- Business lifestyle analysis
- Reporting and testifying
Appendices include a financial discovery checklist, sample Form 1040 and related schedules, and a direct examination checklist.

User Objects
On this page
 - Overview
 - Schema
 - Summary
MongoDB Realm represents each application user internally with a User Object that includes a unique ID and additional metadata that describes the user. You can access user objects in the following ways:
User objects have the following form:
{
"id": "<Unique User ID>",
"type": "<User Type>",
"data": {
"<Metadata Field>": <Value>,
...
},
"custom_data": {
"<Custom Data Field>": <Value>,
...
},
"identities": [
{
"id": <Unique Identity ID>,
"provider_type": "<Authentication Provider>",
"data": {
"<Metadata Field>": <Value>,
...
}
}
]
}
Field
Type
Description
id
string
A string representation of the ObjectId that uniquely identifies the user.
type
string
The type of the user. The following types are possible:
Type
Description
"normal"
The user is an application user logged in through an authentication provider other than the API Key provider.
"server"
The user is a server process logged in with any type of Realm API Key.
"system"
The user is the system user that bypasses all rules.
data
document
A document that contains metadata that describes the user. This field combines the data for all identities associated with the user, so the exact field names and values depend on which authentication providers the user has authenticated with.
Note
System Functions Have No User Data
In system functions, the user.data object is empty. Use context.runningAsSystem() to test if the function is running as a system user.
custom_data
document
A document from your application's custom user data collection that specifies the user's ID. You can use the custom user data collection to store arbitrary data about your application's users. If you set the name field, Realm populates the username metadata field with the return value of name. Realm automatically fetches a new copy of the data whenever a user refreshes their access token, such as when they log in. The underlying data is a regular MongoDB document, so you can use standard CRUD operations through the MongoDB Atlas service to define and modify the user's custom data.
Note
Avoid Storing Large Custom User Data
Custom user data is limited to 16MB, the maximum size of a MongoDB document. To avoid hitting this limit, consider storing small and relatively static user data in each custom user data document, such as the user's preferred language or the URL of their avatar image. For data that is large, unbounded, or frequently updated, consider only storing a reference to the data in the custom user document or storing the data with a reference to the user's ID rather than in the custom user document.
identities
array
A list of authentication provider identities associated with the user. When a user first logs in with a specific provider, Realm associates the user with an identity object that contains a unique identifier and additional metadata about the user from the provider. For subsequent logins, Realm refreshes the existing identity data but does not create a new identity. Identity objects have the following form:
{
"id": "<Unique ID>",
"provider_type": "<Provider Name>",
"data": {
"<Metadata Field>": <Value>,
...
}
}
Field Name
Description
id
A provider-generated string that uniquely identifies this identity
provider_type
The type of authentication provider associated with this identity.
data
Additional metadata from the authentication provider that describes the user. The exact field names and values will vary depending on which authentication providers the user has logged in with. For a provider-specific breakdown of user identity data, see User Metadata.
Note
In general, MongoDB Realm creates a user object for a given user the first time that they authenticate. If you create a test Email/Password user through the Realm UI, Realm creates that user's user object immediately.
 - The user object contains relevant information about the user that you can use in your app logic.
 - The exact information contained in the user object depends on the authentication providers used.

Essay # 1. Meaning of a Departmental Store:
A departmental store is a large scale retail business institution having a number of departments, each specialising in one kind of merchandise and expected to show profit for the department while remaining as a component of the entire business unit. It is, in a technical sense, a horizontally integrated retail business house with all departments under one roof.
In it, each department is a speciality shop such as textile department, drugs department, books and stationery department, video cassette department, etc. A consumer can hope to get all that he needs in a big departmental store.
That is why, it is remarked that a big departmental, store is a place where different sections or departments deal in articles ranging from 'pin to plane'. Such departmental stores are usually located in the central places of big cities.
Essay # 2. Features of Departmental Stores:
The main features characteristics of a departmental store are:
1. It is mostly organised as a joint stock company. Its organisational head is the board of directors with a managing director or a general manager entrusted with the implementation and execution of the policies and programmes formulated by the board. The General Manager coordinates the activities of various departments as their overall chief.
2. It is generally divided into several major sections to facilitate smooth working of the stores.
The major sections in it are shown below in a chart:
3. As regards the day-to-day working, the departments enjoy independence and freedom but all are owned, managed and controlled centrally.
4. It concentrates in one place opportunities for the satisfaction of innumerable wants of the consumers.
5. Having been located in the central place or shopping centers of a city, a departmental store can attract people from all parts of the city and others who came to the city from outside.
Essay # 3. Essential Conditions for Success in Departmental Stores:
(1) The organisational structure of a departmental stores must be sound enough to facilitate coordination among the departments.
(2) The departmental managers must be given due freedom with respect to their day-to-day activities.
(3) The policies and programmes for the management and control must be uniform for all departments.
(4) The shopping for the consumers, particularly housewives, should be easy through a provision of a whole range of goods belonging to different lines in the same building.
(5) Certain services outside the scope of ordinary business such as car parking, cafeteria, telephone, recreational facilities, etc. should be provided to attract the customers.
Lastly, attractive show-windows, display of products, skilled salesmen, low operating costs, etc. are also the essential factors for the success of a departmental store.
Essay # 4. Organisation Structure of a Departmental Store:
Essay # 5. Advantages of Departmental Stores:
As a form of large-scale retail business institution, the departmental store possesses the following advantages:
1. Economy in Purchases:
As regards the purchasing function, a departmental store plays the role of a wholesaler. It buys goods in bulk direct from the manufacturers, enjoys discounts and rebates and credit facilities, and thereby incurs lower freight charges. This centralised buying lowers down the unit cost prices of the goods. Employment of expert buyers for the departments is possible with a view to achieving economy.
2. Effective Advertising:
Being large in size and having diversity in different lines of products and services, a departmental store can afford to advertise on a bigger scale through press and other media of publicity. It can also decorate its departments with attractive show-windows for display of goods with a view to attracting customers.
3. Increase in Sales Turnover:
Having been located in central positions and in popular shopping centers, people from all parts of the city and others who came to the city from outside patronise the departmental store. Moreover, the consumers can buy their requirements of varied kinds under one roof. These factors lead to increase in the sales turnover.
4. Non-Business Services:
A modern departmental store does not confine itself merely to the business activities concerning the products being dealt in through the departments. Various non-business services like car-parking, cafeteria, telephone and telex, and recreational facilities provide additional advantages and benefits which are of definite attraction to the customers.
Essay # 6. Disadvantages of Departmental Stores:
Inspite of the above-stated advantages, a departmental store suffers from the following limitations or disadvantages:
1. Locational Unsuitability:
Due to expansion in the urban conglomeration, the limits of a city have widened. The centralised location of a departmental store becomes unsuitable to the vast majority of consumers who live at rather long distances from the central parts of the city.
According to J. Stephenson, a departmental store can obtain the shopping trade by being centrally located but the trade in articles of everyday use, which are frequently wanted at short notices, goes to their smaller rivals who are located near the houses of their customers.
2. High Operating Costs:
High rental for the premises because of central location in a city, excessive and exotic non-business services (e.g. cafeteria, telephone, etc.) provided, high salaries and wages to the officials and staff, -higher costs of decoration and maintenance, etc. increase the burden of selling expenses.
These have great impact on the fixation of product selling prices on account of these cost factors, and a departmental store finds it difficult to sell the products at reasonable prices. Thus the customers are mostly restricted to the well-to-do sections of the society.
3. Lack of Personal Element:
Like small retail shops, a departmental store cannot attend to the customers' needs and fancies as the customers are lost in the multitude that gathers in the store. The customers who are interested in personal attention by the salesmen do not prefer a departmental store and rather make their purchases from smaller retail stores.

Mosenergo PJSC TPPs use the most environmentally friendly type of fuel
The main fuel used by Mosenergo PJSC is natural gas, the most environmentally friendly type of fuel, due to the fact that its combustion leads to much less harmful substances than other types. The share of gas in the fuel balance came to 99.38%. Mosenergo's power plants as back-up fuels used both coal (0.34%) and mazut (0.27%). Diesel fuel share totaled 0.01% in 2020.
Emissions of pollutants are significantly below the maximum allowable level
Power generating boilers at the power plants are fitted with an automated environmental monitoring system, which allows the concentration of gas pollutants to be monitored in real time and, if necessary, enables plant performance activities to be modified in order to reduce emissions. As a result of subsequent work carried out on the boilers, boiler emissions did not exceed any permitted pollutant emission standards.
The Central Laboratory for Environmental Protection (CLEP) at the Mosenergo Department for Ecology takes measurements at the power plant boilers to determine the flue gas concentrations of nitric oxide, nitrogen dioxide and carbon dioxide and to monitor the temperature of flue gases. The condition of the atmospheric air in residential areas near the TPP are also monitored throughout the year.
Mosenergo operates the mobile eco-monitoring
| ||Mosenergo operates the mobile eco-monitoring based on a Ford car.|
The car is equipped with the necessary equipment for on-site analysis of sewage, emissions into the environment or other polluting sources in the area of Mosenergo TPP responsibility in Moscow and the Moscow Region.

The Healing Properties of Agate Arrowheads: A Holistic Perspective
What are Agate Stones ?
Agate is a unique form of gemstone created via a process that is not fully understood at this time. There are many theories on how it was created. Agate can be found across the planet. It is not a rock in the literal meaning of the term. It is classified as a mineraloid, which is a rock-like structure formed when minerals interact and are subjected to the same environmental stresses as rocks.
Agate is mostly created in igneous rock. They can also occur in metamorphic or sedimentary rock, but such agates are extremely rare. The process begins with the dissolving of silica in water. This water then interacts with a rock, producing agate.
Geodes and agate rock have similar origins. A hollow, pocket, or chamber is found within a rock. These holes are formed by a variety of processes, including gas chambers developing in lava when it solidifies to form igneous rock. These pockets contain water and carbon dioxide, which ultimately leave the chambers. Only the holes remained.
Other causes include pockets formed between sedimentary layers and animal interactions with the rock. The majority of natural pockets are generated via the first way. As a result, basalt rock is a common site for agate formation.
Agate Arrowheads: The Perfect Blend of Aesthetics and Power
Agate arrowheads are not only beautifully made but they are very important historically and spiritually. In the past, arrowheads were used for hunting and fighting though people use them today for their significance and medicinal properties holistically.
Agate arrowheads are specially crafted to bring out the visual and metaphysical properties of a piece of agate, and this same principle applies to the ones found at Alakik Universal Exports. In creating each arrowhead, a balance is struck between perfection in aesthetics as well as in the inherent life force of nature that they embody, suggesting the artist's mastery.
Uses of Agate Arrowhead

Agate arrowheads are great tools for spiritual and emotional healing. Very often they are used in meditation and energy healing to assist in aligning the body, mind, and spirit. Here is how they can be used.
Meditation aid: Holding an agate arrowhead during meditation will assist you in anchoring your energies making you feel more balanced and calm. The stone has a calming influence that clears up the mind thus increasing concentration.
Chakra Balancing: Different kinds of agate match various chakras. Take blue lace agate, for example; it is linked to the throat chakra, inducing lucidity in communication; while moss agate correlates with heart chakra where it helps reconcile emotions by bringing healing."
Protection and Grounding: People say agate arrowheads form a wall against malign energies. Often these objects find their way into buildings or pockets so that one feels safe and secured.
 - Physical Healing
Agate is believed to hold many physical healing properties in relation to holistic health. Some of the things people say about agate are:
Improves Circulation: For enhancing blood flow, it has been speculated that agate could be used in some cases as an alternative medicine meant for toning down heart rate and making sure one has good organ function.
Assists in Digestion: It could possibly help relax the stomach and intestines thereby possibly reducing gastritis amongst other issues concerning digestion.
Strengthen the Immune System: Agate's energy is said to stimulate the immune system, allowing the body to fight off sickness and sustain general health.
Decorative and Collectible Value
Beyond their healing properties, agate arrowheads are highly valued for their beauty. They make stunning decorative pieces, adding a touch of natural elegance to any space. Collectors often seek out these unique pieces for their rarity and craftsmanship.
Benefits of Agate Arrowheads
Emotional Balance and Stability
One major benefit of agate arrowheads is that they help in maintaining emotional balance, adjusting mood swings, lowering anxiety, and in the enhancement of inner tranquility.

We show that the binding energy of the shallow impurity (at the center of the quantum well) ground state is strongly reduced by the presence of a metallic mirror at a few effective Bohr radii from the quantum well. For a given depth of the quantum well, we find that the absolute value of the image potential energy without the metallic mirror is equal to that with a fixed metallic mirror while a certain width of the quantum well is met. Hence, it is proposed that the binding energy of the shallow impurity ground state in the quantum well with and without the metallic mirror can be separately measured by the variation of the width of quantum well. The contribution of the image potential energy to the binding energy of the shallow impurity ground state may then be deduced.

Theoretical analysis of hot electron injection from metallic nanotubes into a semiconductor interface
Metallic nanostructures under optical illumination can generate a non-equilibrium high-energy electron gas (also known as hot electrons) capable of being injected into neighbouring media over a potential barrier at particle boundaries. The nature of this process is highly nanoparticle shape and size dependent. Here, we have derived an analytical expression for the frequency dependent rate of injection of these energetic electrons from a metallic nanotube into a semiconductor layer in contact with its inner boundary. In our derivation, we have considered the quantum mechanical motion of the electron gas confined by the particle boundaries in determining the electron energy spectrum and wave functions. We present a comprehensive theoretical analysis of how different geometric parameters such as the outer to inner radius ratio, length and thickness of a nanotube and illumination frequency affect the hot electron injection and internal quantum efficiency of the nanotube. We reveal that longer nanotubes with thin shells and high inner to outer radius ratios show better performance at visible and infrared frequencies. Our derivations and results provide the much needed theoretical insight for optimization of thin nanotubes for different hot electron based applications.

What is Python pyperclip?
Python pyperclip is a Python Library that can manipulate the clipboard by enabling us to use the copy and paste functions.
Installation
Windows users do not have to download any dependencies, however Linux users need to first install the xclip or xsel library from the command prompt first.
Linux
sudo apt-get install xclip
pip install pyperclip
Windows
pip install pyperclip
Example Usage
pyperclip.copy() is used to copy text into the clipboard.
pyperclip.paste() will return the contents of the clipboard.
The below code will first copy the string "Hello World" to the clipboard. Once the pyperclip.paste() function is called, the same string will be printed out.
import pyperclip
pyperclip.copy('Hello world')
print(pyperclip.paste())
Keep in mind that this library functions like a regular clipboard. If you consecutively copy two values into the clipboard, the first will be over-written. A clipboard can only have one value at a time.
import pyperclip
pyperclip.copy("Hello World")
pyperclip.copy("Goodbye World")
x = pyperclip.paste()
print(x)

Our goal is to understand the structure of subgroups of graphs of groups. This will enable us to prove things like: F \ast_{z} F is LERF.
Exercise 22. A group is coherent if every fg subgroup is fp. Prove that \pi_1 of a finite graph of groups with coherent vertex groups and cyclic edge group is coherent.
Recall, that if H \subseteq \pi_1 \mathcal{G}=G is fg then H has an induced graph of groups structure. \mathcal{H} =H \backslash T_H \subseteq H \backslash T where T is the Bass-Serre tree of \mathcal{G}.
Topologically, H defines a covering space X^H \rightarrow X_g, which inherits a graph of spaces structure with underlying graph H\backslash T.
\Gamma' =H \backslash T_H \subseteq H \backslash T is a finite connected subgraph and the image of \Gamma' in X^H is a connected subcomplex X' such that \pi_1 X' = \pi_1 X^H =H. X' has the structure of a graph of space with underlying graph \Gamma'
There is an explicit algebraic description of H\backslash T, which follows immediately from Lemmas 16,17,18.
Lemma 23. (a) The vertices of H\backslash T are in bijection with \coprod_{v \in V(\Gamma)} H \backslash G/G_v=\coprod_{v \in V(\Gamma)}\{HgG_v\mid g \in G\}.
The vertex HgG_v is labelled by: H \cap gG_vg^{-1}, well-defined up to conjugation in H.
(b) The edges of H\backslash T are in bijection with \coprod_{e \in E(\Gamma)} H \backslash G/G_e. The vertex HgG_e is labelled with H \cap g G_e g ^{-1}.
(c) The edges of H\backslash T adjoining the vertex corresponding to HgG_v are in bijection with \coprod_{e~\mathrm{adjoining}~v} (g^{-1} H g \cap G_v ) \backslash G_v/G_e.
Now we will try to understand this topologically. In particular, we will understand the edge maps of a covering space of a graph of spaces.
Let f:X \rightarrow Y be a continuous map and Y' \rightarrow Y a covering map. If f':X \rightarrow Y' makes the diagram commutes, then f' is a lift of f.
Lemma 24. Fix basepoint x \in X, y=f(x) \in Y, and y' \in Y' mapping to y. There is a lift f':X \rightarrow Y' with f'(x)=y' if and only if f_{\ast} \pi_1(X,x) \subseteq \pi_1(Y',y'). Furthermore, if this lift exists it is unique.
It may be impossible to lift at y'. But it is possible if we pass to a covering space. Eg., if \tilde{X} \rightarrow X is the universal cover. Intuitively, an elevation is a minimal lift.
Definition: Let X,Y,Y', x,y,y' be as above. A based connected covering space (X',x') \rightarrow (X,x) together with a based map f':(X',x')\to (Y',y') such that
commutes is an elevation (of f at y') if whenever the diagram
commutes and X' \rightarrow \bar{X} is a covering map of degree larger than 1 then the composition (\bar{X},\bar{x}) \rightarrow (X,x) \rightarrow (Y,y) does not lift to Y' at y'.
The unbased covering map X' \rightarrow X or equivalently the conjugacy class of the subgroup \pi_1(X') \subseteq \pi_1(X) is called the degree of the elevation f'.
Let \Gamma be a finitely generated group. It has a surjection F_s \rightarrow \Gamma for S finite. Elements of the kernel are called relations and the elements of S are called genereators. Suppose the kernel is generated as a normal subgroup by a subgroup K \subseteq F_S. Then we write \Gamma \cong \langle S|R \rangle to mean \Gamma \cong F_S/ \langle \langle R \rangle \rangle. If R is finite, the \Gamma is said to be finitely presentable.
Example: \mathbb{Z} \cong \langle b,c|bcb^{-1}c^{-1},b^2c^{-3} \rangle.
Let's develop a topological point of view.
Let X^{(1)} be the standard rose for F_S. Each relation r \in R corresponds to a (homotopy class of a) map f_r:S^1 \rightarrow X^{(1)}. We construct a 2-complex X gluing on a 2-cell using the map f_r for each relation r \in R.
Lemma 6: \pi_1(X) \cong \Gamma
Proof: This is a simple application of the Seifert-van Kampen Theorem.
We call X a presentation complex for \Gamma, and we deduce that every finitely generated group is \pi_1 of a 2-complex.
Exercise 8: Every finitely presented group is \pi_1 of a closed 4-manifold.
Therefore, \Gamma acts freely and properly discontinuously on some 2-complex \tilde{X}, the universal cover of X.
Definition: Let S be a finite generating set for \Gamma as above. Then Cay_S(\Gamma)=\tilde{X}^{(1)} is the Cayley graph of \Gamma with respect to S.
To see that this only depends on S, let's give the more standard definition. The vertices of Cay_S(\Gamma) are just the elements of \Gamma. For each generator g \in S, two vertices \gamma,\delta are joined by an edge iff \gamma g=\delta
The group \Gamma acts by left translation.
 1. \mathbb{Z}\cong \langle 1\rangle.
 2. \mathbb{Z} \cong \langle 2,3 \rangle.
 3. The tree for F_S.
Definition: The Cayley graph Cay_S(\Gamma) induces a natural length metric on \Gamma, denoted d_S and called the word metric. Note that d_S(1,\gamma)=l_S(\gamma), the word length of \gamma.
The action of \Gamma on Cay_S(\gamma) is by isometries.
Given a metric space (X,d), a geodesic is just an isometric embedding of a compact interval into X.
A metric space is geodesic if any pair of point is joined by a geodesic. Note that Cay_S(\Gamma) is a geodesic metric space.
Definition: Let \lambda,\epsilon \geq 0. A (\lambda,\epsilon)-quasi isometric embedding is a map of metric space f:X \rightarrow Y such that \lambda^{-1}d_X(x_1,x_2)-\epsilon \leq d_Y(f(x_1),f(x_2)) \leq \lambda d_X(x_1,x_2)+\epsilon.
If for some C, we also have that for every y \in Y, there is x \in X such that d_Y(f(x),y) \leq C, then f is a quasi-isometry.
Exercise 9: Quasi-isometry is an equivalent relation (use the Axiom of Choice).
Exercise 10: Let S and S' be two finite generating sets for \Gamma. Then id:(\Gamma,d_S) \rightarrow (\Gamma,d_{S'}) is a (\lambda,0) quasi-isometry.
Example: (\mathbb{Z}^2,l^1) \hookrightarrow (\mathbb{R}^2,l^2) is a quasi-isometry.

Instead of using Target Disk Mode, there is another way to quickly transfer files between two MacBook Pro machines using Thunderbolt 3. Thunderbolt networking provides a peer-to-peer connection at 10 GbE speeds for super fast local transfers. In the following brief step-by-step tutorial, we'll show you how.
Step 1: Connect both Thunderbolt 3-enabled Macs together with a Thunderbolt 3 cable.
Step 2: Open System Preferences → Network on the Mac you wish to connect to, and you should see a Thunderbolt Bridge with a Self-Assigned IP. If you don't see the Thunderbolt Bridge, simply click the + button to add one, and note the IP address.
Step 3: Ensure that the Thunderbolt Bridge is enabled on the second Mac that you're connecting from.
Step 4: On the Mac that you're connecting to, open System Preferences → Sharing, and enable File Sharing.
Step 5: On the Mac that you're connecting from, open Finder → Go → Connect to Server.

Step 6: In the Server Address box, type the IP that you noted in Step 2, and click Connect.
Step 7: On the dialogue box that appears, enter your login credentials for the machine that you wish to connect to and click Connect.
Step 8: Select the volumes that you wish to mount and click OK.
Step 9: Once connected, the volumes that you selected will show up as shared drives. You can now utilize Thunderbolt 3 to transfer files between both machines much faster than using something like AirDrop.
Step 10: Once finished, eject the drive and disconnect the Thunderbolt cable.
If you'd prefer not to fool with network settings, you can use Target Disk Mode along with a Thunderbolt 3 cable to transfer files quickly between two MacBook Pros. I personally prefer to use the Thunderbolt Bridge method, because it allows me to keep both machines booted into macOS while performing the file transfer.


Referring to the documents and examples of tzip-16, how would one implement the contract metadata on a Fa1.2 contract on SmartPy? In order to provide balance updates and offchain events.
TZip16 uses a two stage approach:
For the specific case of the FA1.2, we will probably simply add the metadata field.
 - Metadata are now supported in SmartPy. – FFF Dec 3 '20 at 23:12
There is no way, to implement tzip-16 on an already originated smart contract unless the contract was originally designed for this purpose, because:
 1. Tzip-16 requires (big_map %metadata string bytes) field in the contract storage.
 2. You can't change the storage structure of an already originated contract.

Starting up your hot tub after a fresh water fill
Before starting up your filled Beachcomber Hot Tub, ensure that the knife valves within your Energy Management System are in the open position to allow water to flow. Also ensure that the bottom Drain and Fill Valve is closed. Open the topside Air Control valves. Turn on your breaker to the hot tub, and turn the FlexJets on at the Topside Controls. You may need to turn the pumps off and on several times to purge the air from the lines. Once your hot tub is running and circulating, it will begin to heat to 100F as a pre-set factory temperature.
To start your hot tub water for the first time, it's convenient to start in the evening. This allows the Conditioning Products the time they need to do their job overnight. Here are the simple steps to follow:
Take a sample of the water, and test pH with your provided kit to ensure it is from 7.2 to 7.8. Adjust with pH Plus or pH Minus. You may need to add Resist to raise Total Alkalinity to prevent pH bounce.
In the evening:
To ensure that no metals or minerals can stain or scale, to prevent rust or corrosion, and to prevent calcium buildup, add one full bottle of Eliminate 1 to the circulating hot tub, and wait 15 minutes.
Add 2 oz. (60 mL) per 250 gallons (1000 liters) of Eliminate 2.
Add 3 1/3 oz. (100 mL) per 250 gallons (1000 liters) of Purezyme 3 to eliminate scum line, prevent odors and cloudy water, and enhance water sparkle.
In the morning:
At this point, you will be ready to shock the water. Refer to the sanitizer program that you are using for your hot tub, shock the water by distributing your sanitizer directly into the circulating, heated water, and wait 15 minutes.
Add 1 oz. (30 mL) per 250 gallons (1000 liters) of Pure Blue to agglomerate particles so that the Microfilter can catch them, to help water sparkle.
For further information on how to achieve that crystal clear water that makes a Beachcomber such a pleasure to use, see our Water Treatment page.


text: In this paper a digital invisible image watermarking technique is proposed based on the numerical simulation of optical Double Random Phase Encoding (DRPE). This technique utilizes the capability of the DRPE to spread the energy of the input information in both the space and the spatial frequency domains using two diffusers. The watermark is in the form of a digital barcode image which is numerically encrypted using a simulation of the optical DRPE process. This produces a random complex image, which is then processed to form a real valued random image with a low number of quantization levels. This signal is added to the host image. Extraction of the barcode, involves applying an inverse DRPE process to the watermarked image followed by a low pass filter. The results presented indicate the feasibility and robustness of the proposed method and it is demonstrated that even when using very few quantization levels, i.e. 2-levels, the watermark can still be extracted with very small errors.

The Cello Biennale and Splendor Amsterdam gave a young cellist carte blanche for one evening in Splendor: Kalle de Bie won the Start in Splendor Prize during the National Cello Competition 2016. Ainsi la Nuit was the result. Featuring Kalle de Bie (cello), Cordelia Paw and Tim Brackman (violin), Martin Moriarty (viola), Nadav Katan and Seán Morgan-Rooney (piano), and visuals by Tessel de Vries.
During this evening, the audience was taken on a musical and visual journey through the suggestive, surrealist world of one of the most innovative composers of France: Henri Dutilleux. In his music, which is poetic and filled with atmosphere, Dutilleux was inspired by Marcel Proust and Charles Baudelaire, through whom he became interested in memories, the subconscious, and dreams.
The music of Dutilleux has never been seen or heard in this way. To have a more intense experience of the mysterious atmosphere, there was a projection on the ceiling of surreal, dark films by different artists during the concert. These illusionary images, edited by Tessel de Vries, will carry the audience through the story of the music, from nostalgia to nightmares.

The UKK 2 km Walk-Test
The UKK walk test (UKK are the initials for Urho Kaleka Kekkonen, founder of the UKK Institute in Tampere/Finland) makes it possible under certain assumptions to determine the approximately max. cardio respiratory efficiency (VO2 max) and therefore the physical condition of the subject. The UKK-walk test is perfectly suitable as a fitness check for fitness clubs or for athletes at schools for example. On the basis of this result a Fitness-Index is calculated with the help of a complex formula taking age, height, weight, test duration and Heart-Rate into consideration, which tells us whether the physical condition of the subject is above or below average. The value of 100 as the average serves as the base. If somebody's index-value is 90 then his physical condition is slightly below average. An index-value of 110 on the other hand would be above average.
The test explains itself by its name. In order to perform the test after having done some warming up and some stretching walk for 2 km as fast as possible (Do Not run!). It is important to keep the walking speed as high as is needed for the subject to achieve 80% of their max. Heart-Rate ( 220 – age). The test duration and heart-rate are measured immediately after finishing the 2 km distance.
As soon as the 2 km distance has been absolved the speed gets reduced to half the speed at the end of the test (2000 m). The Running-Machine operates as described under point "Manual-Mode" (the UP/DOWN-keys are in operation again) with one exception:
The display INDEX instead of indicating the wattage and energy consumption, indicates the test result (calculation following). The LED INDEX is flashing (top right hand side).
The test-result is the index-value which is calculated as follows (according to sex):
INDEX VALUE = 420 + A x 0,2
– (T x 0.19338 + HR x 0.56 + [W : (H2) x 2.6])
INDEX VALUE = 304 + A x 0.4
– (T x 0.1417 + HR x 0.32 + [W : (H2) x 1.1])
A = Age in years
T = Time = neede for 2 km in seconds
HR = HeartRate = average heart rate during the test in bpm
W = Weight in kg
H = Height in cm
Male, Age: 50 years
Weight: 105 kg / Height: 188 cm
Duration of test: 17:34 = 1054 seconds
Heart rate at m: 500 = 158, 1000 = 156,
1500 = 160 and 2000 = 155
Average (158 + 156 + 160 + 155) : 4 = 157 bpm
420 + 50 x 0.2 – (1054 x 0.19338 + 157 x 0.56
+ (105 : (1,882) x 2.6)) = 420
+ 10 - (203.8 + 87.9 + 29.7 x 2.6) = 430
– 368,9 = 61
An index-value of less than 70 is a result quite below average (average=100). Conclusion: Our subject is in need of some indurance training.
Basically the test is suitable for all physically healthy persons between the age of 20 and 65. The results will be less accurate with people with overweight. Athletes usually do not reach the required heart-rate when performing the test. The results will also be less accurate with elderly people.
First it has to be mentioned that the UKK-Test has not been designed for individual tests but for a larger amount of subjects. i.e. testing of a crowd of people at the same time by sending them off in 1/2 minute intervals on the 2 km-distance track. Therefore originally the UKK-Test has not been designed as a typical test for the running machine.
Advantages of performing the ukk walk-test on the running-machine: Being able to measure the precise time and distance of the test (it is exactly 2 km) and Heart-Rate control during the test. Direct test documentation via the printer interface.

Registering Strategies
Intended for plugin developers as a way to make it easy to use
strategies there is the possibility to register a strategy without loading it.
 Authentication.register(:my_strategy, "/absolute/path/to/strategy.rb")
This then allows developers to use
Providing feedback to users (Error Messages)
There's at least 4 ways to provide feedback to users for failed logins.
 - Overwrite Merb::Authentication#error_message The return of this method is
 the default message that is passed to the Unauthenticated exception. Overwrite
 this to provide a very basic catch all message.
 - Provide a default message when you declare your before filter.
 before :ensure_authenticated, :with => [Openid, :message => "Could not log you in with open ID"]
 - OR
 before :ensure_authentication, :with => {:message => "Sorry Buddy… You Lose"}
 When you pass a message, it will replace the Merb::Authentication#error_message default for this
 - Use an after filter for your login action. This can be used to set your messaging system. For example:
 after :set_login_message, :only => [:create]
private def set_login_message if session.authenticated? flash[:message] = "Welcome" else flash[:error] = "Bad.. You Fail" end end
 - Use the authentications error messaging inside your strategies to set error messages there.
 You can add to these errors just like adding to DataMappers validation errors.
session.authentication.errors.add("Label", "You Fail")
Add as many as you like, ask session.authentication.errors.on(:label) to get specific errors etc Really… They're just like the DataMapper validation errors. The bonus of using this system is that you can add messages inside your Strategies, and then in your views you can do this:
<%= error_messages_for sessions.authentication %>
Additional checks / actions to perform after the user is found
Sometimes you may need to perform additional operations on the user object
after you have found a valid user in the strategy. There is a hook method
Merb::Authentication.after_authentication which is designed for this.
Here's an example of checking that a user object is active after it's been
Merb::Authentication.after_authentication do |user, request, params|? user : nil end
Pass the user model on if everything is still ok. Return nil if you decide in the
after_authentication hook that the user should in fact not be allowed to be authenticated.
By default this plugin doesn't actually
authenticate anything ;) It's up to you to get your model going, and add an
authentication strategy.
To logout use
session.abandon! and to force a login at any time use
raise Unauthenticated, "You Aren't Cool Enough"

Specify ciphers allowed for protocol version 2
Use this group policy to specify the ciphers allowed for SSH protocol version 2. If you enable this policy, you can add or delete ciphers to increase the speed of SSO.
Multiple ciphers must be separated by commas. If you want to add a cipher to the list, use the '+' character at the beginning of the name. If you enter the name only, you will replace the existing ciphers with the new cipher.
The order of the cipher list will determine the order that sshd uses the ciphers. For example, if you want to increase the speed of SSO, you can place the cipher, aes128-ctr, at the beginning of the list.
When this policy is disabled, the default cipher list, which is the most secure grouping, is used, but may cause delays in SSO.
To enable this group policy, you must be running Centrify OpenSSH 5.3.0 or later.
This group policy modifies the Ciphers setting in the following file: /etc/centrifydc/ssh/sshd_config

This page is about the Automatic Activation Device for parachutes. For the tree family, see Cupressaceae. For the Mediterranean island, see Cyprus. For the law doctrine, see Cy-près doctrine.
CYPRES 2 Student panel
CYPRES is an acronym for Cybernetic Parachute Release System. It refers to a specific make and model of an automatic activation device (AAD), a device that automatically activate a parachute (typically as a reserve system for a skydiver) under certain circumstances. A CYPRES is designed to activate the reserve parachute at a preset altitude if the rate of descent is over a certain threshold. The manufacturer of the CYPRES is Airtec.
The CYPRES works by using a cutter to cut the reserve container closing loop. A spring-loaded pilot chute then leaves the container and breaks through the skydiver's slipstream to begin reserve deployment.[1]
The CYPRES comes in four different models: Expert, Student, Tandem and Speed. The basic operation of the units is the same; only the activation parameters are different, having been optimized for different types of skydiving.

Following entry into force of patent law amendments, the Serbian IPO introduced an Executive Order regulating the patent application filing procedure in more detail.
The Order, which entered into force on November 9, 2019, elaborates on certain amendments to provide for their implementation. The most significant changes brought by the Order are the following:
When filing a patent or petty patent application in electronic form, the attachments submitted along with the application will be considered as original documents due to the use of a qualified electronic signature. Most significantly, this means that it is no longer required to submit an original Power of Attorney in paper form after applying electronically. An original Power of Attorney is still required for applications filed in paper form, therefore the procedure for traditional applications remains unchanged.
The Serbian IPO will keep a Patent Register and a Petty Patent Register in electronic form only. Patent and petty patent registers in paper form no longer exist, while the registers of patent and petty patent applications have been abolished altogether.

To craft the sculptural mirrors Mastrangelo used sand sourced from various locations around the world.
The form is created from sand mixed with epoxy resin to create three-dimensional geometric forms that is meant to emulate the appearance of volcanic formations. Mastrangelo hand dyed the gritty terrains, to give them a unique black colour, which were then attached to mirrors that have reflective gold-tinted faces.
"Though the material is not literally magma from a volcano, Mastrangelo has used his signature materials and methods to masterfully emulate the unique way that magcalcifies into igneous rock formations," the studio told Dezeen.
Magma forms part of a series of work that the designer has created to draw attention to the climate change crisis by mimicking natural forms.
As with the other works – which include a rug collection influenced by the patterns of breaking ice sheets and mirrors and tables modelled on snow melting on mountain peaks – its form and materiality are intended to provoke a message warning of the effects climate change has on the beauty of nature.
"The forms and textures suggest a landscape that has surpassed healthy temperatures and decayed to an existence of extreme heat," said the studio. "It is through Magma that Mastrangelo hopes viewers will consider their stake in climate change."
"For me, the Magma series references the global tension and worry in regards to our impending climate crisis," Mastrangelo added. "I feel that there is so much pressure rising to the surface and it's bound to erupt; I hope not in the form of disaster but in the form of energetic action."
Each frame was individually commissioned and unique-in-form. For Magma Edition 01 the designer sculpted black sand to cover most of the reflective surface apart from a small triangular shaped opening, it is on display at 1stDibs Gallery in New York City.
An arch frames the mirror of Magma Edition 02, which can be viewed at Mastrangelo's studio in Brooklyn.

Difference Between Trade or Non-Trade Cement
What is Cement?
Cement is a binding material called binding agent. We know cement is a main ingredient of building materials.
Cement is a commonly used binding material in the construction. The cement is obtained by burning a mixture of calcarious (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in 1924. He patented it as Portland cement.
Cement Marketing are two types
 1. Trade Cement marketing
 2. Non-Trade Cement Marketing
What is Trade Cement?
Trade cement is sold by the manufacture to the dealers and distributors, who in turn sell to the consumers.
 - Cement dealer, buy directly from cement company and sell also do retail sale from his shop.The dealer is incentive's to sell the product.
 - Trade cement are costly than non trade cement. All taxes to be paid at the time of delivery while in non trade cement taxes can paid in any month of financial year.
 - Selling Price involves share of dealers, retailers etc.

Trade Cement BAG
What is Non-trade Cement?
Cement sold to direct customer like a construction company for self consumption (their project use), not to be resold to a third party falls under NonTrade Category.
non-trade cement
on Non-Trade cement bag written (Not for retail sale)Its Mean this type of cement bags is coming direct from plant.
 - Non-trade cement is that which sell by the manufacturer directly to the consumer (Builder, Contractor or and Institution involve in any project, NGO or Government). The dealer bypass.
 - Non-trade cements do not have heavy overheads and are cheaper as compared to trade cements. Consumers such as realtors, contractors, etc., purchase in bulk from the manufacturer.
 - In non trade the company can directly dispatch material from its factory to the destination of buyer without any doubt of middle men meddling with the product.

Machine Vision Implementation in Rapid PCB Prototyping
Image processing, the heart of machine vision, has proven itself to be an essential part of the industries today. Its application has opened new doorways, making more concepts in manufacturing processes viable. This paper presents an application of machine vision in designing a module with the ability to extract drills and route coordinates from an un-mounted or mounted printed circuit board (PCB). The algorithm comprises pre-capturing processes, image segmentation and filtering, edge and contour detection, coordinate extraction, and G-code creation. OpenCV libraries and Qt IDE are the main tools used. Throughout some testing and experiments, it is concluded that the algorithm is able to deliver acceptable results. The drilling and routing coordinate extraction algorithm can extract in average 90% and 82% of the whole drills and routes available on the scanned PCB in a total processing time of less than 3 seconds. This is achievable through proper lighting condition, good PCB surface condition and good webcam quality.

Definitions for absorption, electric
The Standard Electrical Dictionary
A property of the static charge. When a Leyden jar is being charged it dilates a little and the capacity increases, so that it can take a little more charge for a given potential difference existing between its two coatings. This phenomenon occurs with other static condensers, varying in degree with the dielectric. With shellac, paraffin, sulphur and resin, for instance, the absorption is very slight; with gutta-percha, stearine, and glass, the absorption is relatively great. The term is due to Faraday. Iceland spar seems almost or quite destitute of electric absorption.

Objectives Accurate and stable extrinsic parameter calibrations are the basis of fusing perception and positioning of cameras and light detection and ranging (LiDAR). To address the problems of the Dhall calibration method in constraint accuracy, stability, and convergence, this paper proposed a LiDAR and camera calibration method with joint point-line-plane constraints.
Methods First, line-line and plane-plane constraints were added, and the Kabsch method was used to obtain a closed-form solution, which reduced the influence of noise in the single corner constraint and improved the accuracy and stability of the calibration results. Then, multi-frame point clouds were superimposed to fit lines, and the fitting corners were averaged, which further reduced the influence of the point cloud noise, thus improving the convergence speed and stability of the calibration method.
Results Experimental results show that the proposed method can converge within 20 frames, and the reprojection error of the corner points was less than 2 cm.
Conclusions The proposed method has faster convergence speed and higher accuracy than the original method.


Today's name is Mongo
The name "Mongo" conjures up memories of Blazing Saddles for many of us of a certain age (and thoughts of a hospital for magical maladies for others). However, it is, in fact, a completely period name. It is a variant form of Mungo, the given name of the Scottish saint who is the patron of salmon and of the city of Glasgow. As Mongo, it appears in Scots records as a given name dated to 1490 and c. 1592. [1] In the spelling Mongow, it also appears in Scots records dated to 1579.[1]
Additionally, in one of those odd coincidences that often happens with language, "Mongo" is also a Mongol descriptive nickname meaning "silver."

text: La3+-doped BaSnO3 microtubes (La3+–BaSnO3) have been synthesized by electrospinning method, and the influence of La3+ content on the sensing properties of BaSnO3 for detection of formaldehyde vapor has been investigated. The as-prepared materials have been characterized using XRD, SEM, DSC, XPS, and UV-Vis. The La3+–BaSnO3 sample doped with 4 wt% La exhibited a response as high as 220 to formaldehyde vapor (1000 ppm concentration) along with a very low detection limit of 0.1 ppm at 270 °C, whereas at 140 °C, it exhibited a response of 80 and detection limit of 1 ppm. In addition, the sensor showed excellent selectivity of 57 to formaldehyde at 140 °C when compared with other vapors. Further, the sensor also showed good repeatability and stability over a long period of time suggesting its strong potential as a commercial formaldehyde sensor.

Helichrysum water (hydrolat)
French National Ecological Agriculture biologiques Certificate
Helichrysum water (hydrolat) is obtained by distillation of helichrysum plants. It contains a small amount of helichrysum essential oil and other substances very useful for skin.
Helichrysum has long been considered to be youthful plant. Hydrolat has a subtle flavor and can be used in all types of skin. Helichrysum hydrolat is suitable for all skin types. This water has astringent properties, for this reason, it is suitable for skin with dilated capillaries, helps to reduce swellings, bruising. Helichrysum water helps to regenerate the skin, promotes the formation of new cells, soothes irritated skin.
Helichrysum water is used before applying the cream or oil; it absorbs better into the skin and the greasy feeling disappears. Hydrolat can be used as a tonic to remove the traces of make-up and to freshen the skin.
