Like many canal systems worldwide, water quality in South Bethany's canals is severely degraded. Poor circulation, sediment accumulation, low oxygen levels, excessive nutrients, and pollution have led to declining shellfish communities, pungent and harmful algae blooms, and fish kills. Based on a concept developed by Lloyd Hughes, a former councilman and retired engineer, the town of South Bethany commissioned the team of Oceaneering International Inc. and KCI Technologies Inc. to evaluate the feasibility and develop preliminary designs for a tidal pump using only tidal differential to power the system.
Engineers explored possible scenarios for alignment, configuration, materials and construction methods to further define the tidal pump concept and determine a potential cost and implementation schedule. Effective hydraulic analysis posed a crucial design challenge because of the low head differential and resulting low operating velocities. To deliver the required circulation through the system, each component had to be optimized for flow performance by reducing friction wherever possible.
The proposed tidal pump system would utilize almost two miles of underground piping, two ocean outfalls located 30 feet below sea level, and an innovative diffuser system configured to dissipate velocity during the exchange. Once constructed, residents could see improvements in water quality in as little as a month, as the tidal pump fully flushes the canals every 30 days.

Knowledge Management Challenges in Public Sectors
The emerging trend in economy offers great opportunities, but at the same time it creates some concerns and challenges for private and public sectors. To overcome the issues and take advantage of the opportunities, governments need to consider the innovations and invest on some initiatives and adapt new management methods in private sectors. Knowledge Management (KM) is a way that needs to be explored for taking the opportunities and their implicit benefits in future. Therefore, it is also necessary to address the key issues and opportunities in public sectors. The aim of this article is to advance the understanding of KM concepts at the organization and the enterprise levels in the public and private sectors in knowledge economy and to develop a framework identifying good practices of KM. People, processes, and technologies are main elements to be considered for the public-sector KM framework.

Vacuum Sealing Apples to Freeze
Perhaps one of the best ways to preserve apples for later use is the vacuum sealer, which is readily available on the internet or, perhaps, local appliance stores. There are several manufacturers that make these sealers, but the basic procedure is the same.
Basic Equipment Required
The basic equipment necessary for freezing apples is as follows:
1. Large stainless steel or enamel cooking pot to blanch the apples in.
2. Large bowl for the pre-treatment of the apples.
3. Apple corer and sharp paring knife.
4. Long handled slotted spoon to remove apples from blanching pot.
5. Cider vinegar or lemon juice to a ratio of 1 tablespoon to 1 quart of water for pre-treatment solution for apples. NOTE: Some fruits, such as berries, cranberries, grapes, strawberries and rhubarb, will not need this pre-treatment process in order tofreeze. The pre-treatment is basically used to prevent discoloration of light fleshed fruits such as apples, apricots, peaches and pears.
6. Vacuum sealer with bag rolls.
7. Any sugar or spices, such as cinnamon, that you would like to sprinkle on the fruit before freezing.
Method of Vacuum Sealing Apples
Step 1: Choosing Apples for Freezing
Always use the freshest, ripest, most blemish-free apples available when purchasing for home freezing projects. Inspect for blemishes and separate the damaged fruit from the good.
Step 2: Preparing for Blanching
Fill the large cooking pot about two-thirds to the top with water and bring to a slow, gentle boil. While the water is coming to a boil, prepare the apples.
Step 3: Preparing the Apples
Wash, core and slice the apples into wedges. (I do not peel the apples I use in apple pies.) If you prefer your apples peeled, then that will also need to be done in this step.
Peeling can be time consuming if you are processing a lot of apples. There are several methods to accomplish this task, some of which are specifically designed to peel apples, pears and other firm fleshed fruits.
The traditional equipment for this chore is a sharp paring knife or vegetable peeler. Apple corers are also helpful for slicing and coring apples quicker in preparation for pre-treatment.
One of the most efficient ways of peeling apples is by using a manual Apple Peeler and Corer, pictured below. In one easy step it allows you to peel, slice and core an apple in less than 15 seconds! These machines often lets you choose whether or not you want the apples just peeled, or peeled, cored and spirally sliced. With a little practice, you will be able to adjust the machine to your specific requirements and become a pro at peeling apples in record time.
Step 4: Pre-treating the Apples
Pre-treat the apples by soaking the slices in a solution of 1 tablespoon of apple cider vinegar or fresh squeezed lemon juice to 1 quart of water, (to make a larger amount of pre-treatment, double the above solution recipe), for a minute or two per layer of fruit. Pre-treat the fruit in batches, one layer at a time, until all of the fruit has been pre-treated.
Step 5: Blanching the Apples
Lift fruit out of the pre-treatment bowl with the slotted spoon and drop into the pot containing the boiling water for blanching.
Blanch the fruit for two minutes or so in single layers, and remove from the boiling water into the emptied large bowl that was used to pre-treat the fruit. If you are going to add spices or sugar before freezing, now is the time that you do that. Sprinkle the cinnamon, or other spices, and/or sugars, if desired, over the fruit and stir gently to coat.
Step 6: Vacuum Sealing the Apples
Make a bag big enough for the batch of fruit to be filled into. I like to package the fruit in quantities that would be required for a pie...usually 4 to 6 cups or so (check your fruit pie recipe for specific proportions for your favorite pies).
Place prepared fruit into the sealer bags and load into the front of the vacuum sealer, as pictured below.
Once the opened end has been inserted into the sealer, turn on the sealing machine. As the air is vacuumed out of the bag, re-adjust the bag by lifting it upward to the level of the sealer and guide as much of the air as possible from around the apple slices up toward the sealer.
Once the machine detects that as much air as possible has been removed from the bag, the sealing element engages to seal the bag. The machine will automatically switch off when the process is complete.
Press the button on the top of the machine to release the vacuum seal that has developed during the sealing process. This will release the seal plates and the bag will be easily removed.
If, when the bag is removed from the machine, air rushes back into the bag, then the seal was compromised. Cut off the bad seal, if possible, and reseal the bag.
If you are having trouble getting the bag to seal, then there is probably too much liquid being sucked into the sealer elements, not allowing the machine to connect properly. Drain some of the liquid out of the bag and try again.
Step 7: Freezing the Apple Bags
Place the apple bags into the freezer as flat as possible in a single layer until frozen. Once frozen, the bags can be stacked to minimize the space required to store the apples in the freezer.

About Write Filters in Windows Embedded
Updated: January 1, 2013
Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2
For operational reasons, it might be undesirable to write to storage media in Windows Embedded devices. By redirecting all write requests to either a separate disk partition or RAM, a write filter allows the run-time image to maintain the appearance of a writable run-time image without committing the changes to the storage media.
Starting with Feature Pack 2007 for Windows XP Embedded Service Pack 2, the following write filters are available:
File-Based Write Filter, which operates at the file level
Enhanced Write Filter, which operates at the sector level
Enhanced Write Filter and File-Based Write Filter redirect all writes targeted for protected volumes to a RAM or disk cache called an overlay. The overlay stores changes made to the operating system but is removed when the device is restarted, restoring the device to its original state.
Enhanced Write Filter works at the sector level on protected disks and allows you to commit changes so that they persist when the device is restarted. Enhanced Write Filter is useful for thin clients that do not need to store cached information or receive frequent updates. Changes made to a system protected by Enhanced Write Filter are stored in one or more layers that represent snapshots in time. Applying changes to an image applies all changes made to the operating system during a specific period of time.
File-Based Write Filter works at the file level instead of the sector level on protected disks. By default, File-Based Write Filter protects the whole disk, but selective write through exceptions can be granted to specific files and folders. Writes to folders which have been granted exceptions persist when the device restarts.
Windows Embedded also features a registry filter, which monitors all writes to the registry and stores changes in a separate layer that is discarded when the device restarts. For registry writes, the registry filter supports persisting specific registry changes by using registry monitors when the device restarts. This feature is independent from Enhanced Write Filter and File-Based Write Filter and can be used regardless of your specific configuration.

General Software Update Processes with Enhanced Write Filter or File-Based Write Filter
When you use Enhanced Write Filter or File-Based Write Filter protection on the drive for the Windows Embedded device, all uncommitted writes to the device are lost when the device restarts. This includes any software or software updates that have been installed. To persist changes when the device restarts, Enhanced Write Filter or File-Based Write Filter must be turned off prior to performing the change actions, or the changes must otherwise be explicitly committed to the drive using the commit command. This is required regardless of the method used to install software or software updates.
You can take the following steps to persist changes when the device is restarted.
To disable and then enable the write filter
Disable Enhanced Write Filter or File-Based Write Filter. Disabling the filter takes effect after the next device restart. All changes to the system made prior to the device restart are discarded before Enhanced Write Filter is disabled.
Note An alternative to this step is to use the -commitanddisable command for Enhanced Write Filter which will cause all pending write operations to be committed to the storage device before the filter is disabled. This is not recommended because it commits an unknown number of changes to the storage device.
After the device restarts, all new changes are written directly to the storage device. The drive remains unprotected until Enhanced Write Filter or File-Based Write Filter is re-enabled.
The required changes can now be made, such as installing or updating software, and changing system settings.
After the necessary changes to the system have been made, Enhanced Write Filter or File-Based Write Filter can be re-enabled. This causes Enhanced Write Filter or File-Based Write Filter to be enabled after the next device restart. All changes prior to the restart are saved on the storage device.
After restarting the device, the system returns to a protected state.
Note If this procedure fails at any point after disabling the write filter, the system is left in an unprotected state.
To use the commit command to write changes
Restart the device to clear any changes that were made to the protected volume.
Make the required changes to the system, such as installing or updating software, and changing system settings.
Issue the commit command to cause all changes made to the system to be committed to the storage device after next device restart.
After restarting the device, any changes to the system are committed and the system returns in a protected state.
If any items that have been installed require the device to be restarted, a second restart might be required. Any changes caused by this second restart are automatically committed to the storage device.
Although the second method does not completely disable the write filter, both methods write the entire contents of the overlay to disk, regardless of the source of the changes. The second method might also require an additional device restart and commit action to account for installations that have post-restart actions, such as file replacement or drivers or services being installed. With the first method, you can handle any additional restarts as part of your software installation before re-enabling the write filter.
The use of write filters on Windows Embedded imposes unique requirements on system administrators who are tasked with change management. One option for administrators is to use a script to automate the additional actions needed to complete a software or software updates installation. For a sample script that performs these write filter modifications, see Example Script for Configuring Write Filters Using Configuration Manager 2007 on Windows Embedded Devices.
For additional information, see Configuration Manager 2007 Information and Support.

When it comes to flowers, the red rose is one of the most iconic and meaningful of all. The vibrant color of the rose, paired with its sweet fragrance, has made it a favorite for centuries. But did you know that the red rose is more than just a pretty flower? It has been imbued with symbolism and spiritual significance throughout history. In this article, we'll explore the many meanings of the red rose, from its origins in mythology to its modern-day use in aromatherapy and skincare.
The History of the Red Rose as a Symbol of Love and Passion
The association between the red rose and love can be traced back to ancient Greece and Rome. In these cultures, the rose was seen as the symbol of Aphrodite, the goddess of love and beauty. The red color of the rose, which was associated with the god of love, Cupid, reinforced its romantic connotations. Over time, the red rose became the go-to flower for expressing love and passion, and it has remained so to this day.
During the Middle Ages, the red rose continued to be associated with love and passion, but it also took on religious significance. It was believed that the red rose was a symbol of the blood of Christ, and it was often used in Christian art and literature to represent the love of God. This dual symbolism of the red rose as both a romantic and religious symbol helped to solidify its place in history as a powerful and enduring symbol of love.
In modern times, the red rose remains one of the most popular flowers for expressing love and passion. It is often given as a gift on Valentine's Day, anniversaries, and other romantic occasions. However, the meaning of the red rose has evolved over time, and it can now also be used to express gratitude, appreciation, and admiration. Whether given as a romantic gesture or as a symbol of friendship, the red rose continues to be a beloved and timeless symbol of love and passion.
The Origins of the Red Rose in Mythology
According to Greek mythology, the red rose came into being when Aphrodite's tears mixed with the blood of her lover, Adonis. The resulting flower was said to symbolize both love and sacrifice. In Roman mythology, the red rose was linked to Bacchus, the god of wine. It was believed that the first red rose sprung from the ground where a drop of his spilled wine had landed.
However, the red rose also has significance in other cultures. In Hindu mythology, the goddess Lakshmi is often depicted holding a lotus flower and a red rose, symbolizing beauty and prosperity. In Chinese culture, the red rose is associated with good luck and is often given as a gift during the Chinese New Year.
Today, the red rose remains a popular symbol of love and passion, often given as a gift on Valentine's Day or used in wedding bouquets. It is also used in various industries, such as perfumery and cosmetics, due to its sweet fragrance and vibrant color.
How the Red Rose Became the National Flower of England
The red rose has been associated with England since the time of the Wars of the Roses, a series of conflicts between the House of Lancaster and the House of York for control of the English throne. The House of Lancaster, which represented the reigning monarch at the time, adopted the red rose as its emblem, while the House of York chose the white rose. This rivalry culminated in the Battle of Bosworth Field in 1485, when the red rose emerged victorious. From that point on, the red rose became the national flower of England.
Interestingly, the red rose was not officially recognized as the national flower of England until 1986. Prior to that, there was no official national flower for the country. However, the red rose had already become a symbol of England and was widely recognized as such. Today, the red rose is still a popular symbol of England and is often used in national celebrations and events.
The Different Varieties of Red Roses and Their Meanings
Not all red roses are created equal. There are many different varieties of red roses, each with its own unique meaning. For example, the deep burgundy color of the Black Baccara rose is said to represent unconquerable love, while the bright scarlet red of the Mr. Lincoln rose is associated with passion and strength.
Other popular varieties of red roses include the Cherry Brandy rose, which has a vibrant orange-red hue and symbolizes enthusiasm and desire, and the Firefighter rose, which is a deep red color and is often given as a tribute to firefighters and other first responders. Additionally, the Red Eden rose is a bright red color and represents true love and devotion, while the Red Intuition rose is a darker shade of red and is associated with deep feelings of love and respect.
The Significance of Giving a Red Rose to Someone Special
When you give a red rose to someone, you're not just expressing your love or admiration for them. You're also telling them that they are special and unique. The act of giving a red rose can be a way of expressing gratitude, saying thank you, or congratulating someone on a job well done. It's a timeless gesture that never goes out of style.
Moreover, the color red itself holds a significant meaning. It symbolizes passion, desire, and love. It's no wonder that red roses are often associated with romantic love and are a popular choice for Valentine's Day. However, red roses can also be given to family members, friends, or colleagues to show appreciation and affection. The beauty and fragrance of a red rose can brighten up anyone's day and make them feel special.
The Importance of Color in Flower Symbolism: Why is Red so Significant?
Color is an important part of flower symbolism, and the color red has its own special significance. Red is associated with passion, desire, and energy. It's a powerful, attention-grabbing color that commands respect and admiration. When you give someone a red rose, you're telling them that they ignite your passion and that you desire them deeply.
In addition to its association with passion and desire, red is also often used to symbolize love and romance. Red roses are a popular choice for Valentine's Day and anniversaries, as they convey a message of deep love and commitment. Red flowers can also be used to express gratitude and appreciation, as they are a bold and striking way to say "thank you."
However, it's important to note that the meaning of red flowers can vary depending on the culture and context in which they are given. In some cultures, red is associated with luck and good fortune, while in others it may be seen as a symbol of danger or warning. It's always a good idea to research the cultural significance of flower colors before giving them as a gift or using them in a symbolic way.
Understanding the Spiritual Significance of the Red Rose in Different Religions
The red rose has spiritual significance in many different religions. In Christianity, the red rose has been associated with the blood of Christ and is seen as a symbol of sacrifice. In Hinduism, the red rose is associated with the goddess Lakshmi and is used in worship and as an offering. In Islam, the red rose is said to represent the love between God and humanity and is often used in poetry and art.
Additionally, in Buddhism, the red rose is seen as a symbol of the Buddha's teachings and is often used in meditation practices. The rose's beauty and fragrance are believed to represent the beauty and fragrance of the Buddha's teachings, which bring peace and enlightenment to those who follow them. In ancient Greek mythology, the red rose was associated with the goddess Aphrodite, who was the goddess of love and beauty. The rose was said to have grown from her tears and the blood of her lover, Adonis. Today, the red rose is still a popular symbol of love and is often given as a gift on Valentine's Day or other romantic occasions.
How to Care for Your Red Rose Plants and Keep Them Blooming Beautifully
If you want to keep your red rose plants blooming beautifully, there are a few things you need to know. Red roses love sunlight, so make sure to plant them in an area that gets at least 6 hours of direct sunlight per day. They also need well-draining soil and regular watering. Pruning your red roses can help promote healthy growth and keep them looking their best.
Using Red Roses in Floral Arrangements: Tips for Designing Stunning Bouquets

By "compatible" I mean, if $R$ is my relation and $+$ my operation, then if $aRb$ and $cRd$, then $(a+c)R(b+d)$. For an congruence relation this is claimed, but also that $R$ must be an equivalence relation, but there are relations, like $<$ that fulfill the first statement, but are not equivalence relation's. Are there any terms for such relations and are they studied in mathematics?

You have chosen the right word, compatible is a standard technical term for the notion. – André Nicolas Feb 1 '13 at 19:33

...are they studied in mathematics?
Considering a functional relation $R$, the compatability says, in functional notation: $R(a+c)=R(a)+R(c)$. In other words, the function preserves that operation. Of course we study examples of such relations all the time whenever we are looking at homomorphisms!
If you're asking if relations in general are studied this way, then maybe so. While searhing I came across a paper by Saunders MacLane which looks like a relevant example:
He talks about regarding a homomorphism of things in a category with an operation $S\rightarrow B/L$ instead as a "many valued function" from $S$ into $B$ (that is, every pre-image is related to the multiple things in the coset of the image). It remains "compatible", but is no longer a true function.
share|cite|improve this answer
Another way to look at R preserves the operation is that it commutes with it. But is this the same setup as the OP's? $aRb \wedge cRd \to (a+c)R(b+d)$ versus $R(a+b)=R(a)+R(b)$? There are obvious distinctions such as the number of arguments, implication versus equality, and also in the first case there is a conjunction and $+$, while in the latter only $+$ operator. – alancalvitti Feb 2 '13 at 2:13

Java Question
Google-app-engine datastore multi-dimensional arrays
I have a class that runs as a cron job (every 5 minutes or so) and it produces a multidimensional array. I then want to access this array from another class.
Is it possible to just put() a whole md-array as a single object into the datastore? And then to get() that md-array in another class?
If so, is it similar to just putting other simple variables into the datastore?
Cheers for any help
Answer
No, you cannot directly store a multi-dimensional array as a property of a datastore entity. The closest type would be a ListProperty, but this will only store one dimension. (Python only, not for Java)
Depending on what the data in your md-array represents, you could:
 - Serialize the values into a byte array, which you store as a Blob (1 MB size limit)
 - Flatten the array and store each dimension as an individual property
 - Create an entity for the rows, and properties for the columns (if 2-dimensional)
For all supported datastore property types, see this section of the GAE documentation


WEARING A TORQUE OF STUNNING IRIDESCENT GOLD MAKES THIS BIRD AN ABSOLUTE MUST SEE – MEET THE GOLDEN-COLLARED MANAKIN!
Spread the love
An elaborate dancer he puts his gorgeous golden band to good use, a must-see when he is putting on the moves!
MEET THE GOLDEN-COLLARED MANAKIN
The Golden-collared manakin (Manacus vitellinus), is a species of bird in the Pipridae family. A rather compact, rotund little bird with a short tail, and rounded wings, they also have a big head with red-orange legs. The male of this species wears a stunning yellow collar right around his throat, fading to olive down his breast and belly. Above this collar, he is mostly black, with the center of his back also being black changing to a darker olive.
Overall, when compared to the male, the female is a dull olive-green above, becoming paler and more yellowish olive green below.
Related Reading:
Their wings are able to make a snapping and buzzing sound.
Golden-collared manakins are endemic to and found in Costa Rica, Panama, and Colombia.
These birds like to live in subtropical and or tropical moist lowland forests, though they have adapted to secondary growth wooded areas as well.
Golden-collared manakins like to dine low in the trees on fruit as well as taking some insects, both of which are taken from available trees and in flight.
Males of this species perform an elaborate dance in a cleared lek area on the forest floor. Once a female has chosen a mate, she builds a small shallow, open, cup-shaped nest made from fibrous vegetation and animal hair, near ground level. She then goes on to lay two eggs within colored to look like dead leaves and incubates them for 14 to 24 days.
Once they hatch the chicks are fed by their mom for 10 more days before leaving the nest. Young may follow their mom for around a month before becoming independent. Due to their wide range and relatively stable population these birds are listed as of Least Concern on the IUCN list.

Media release: First assessment of its kind shows environmental impact of the full range of aquatic foods to help guide more sustainable production and diets
Wednesday, Sept. 15, 2021 (Halifax, NS) – A landmark study has shown what kind of toll the production of a variety of aquatic or 'blue foods' has on the environment, while highlighting the significant unfulfilled potential for aquaculture to become more sustainable.
The research, titled the "Environmental performance of blue foods," was one of five initial scientific papers published today as part of the Blue Food Assessment (BFA).
The authors, from Dalhousie University and several other international institutes, produced the most standardized assessment of the environmental pressures stemming from 'blue food' production to date. It covers nearly three quarters of global production and draws on studies reporting data from more than 1,690 fish farms and 1,000 unique fishery records worldwide.
The paper finds that seaweeds and farmed bivalves, such as mussels and oysters, generate the fewest greenhouse gas and nutrient emissions, like phosphorous and nitrogen, and use the least land and water. Capture fisheries also result in few nutrient emissions and use limited land and water. Compared to farmed fish, however, the researchers found greenhouse gas emissions range from relatively low, for such species as sardines and cod, to relatively high for flatfish and lobsters.
"Our results highlight not only the large differences in environmental impacts between and within major sources of blue foods across these environmental stressors, but confirm the important role that many blue foods can play in reducing the impacts of human diets," says Peter Tyedmers, a co-author and professor in Dalhousie's School for Resource and Environmental Studies.
Commonly eaten farmed finfish, such as salmon and carp, outperform other farmed blue foods on several environmental indicators, while most blue foods outperform chicken, which generates similar environmental pressures as tilapia, one of the more impactful blue foods assessed.
This new set of standardized metrics can be used to benchmark the environmental impacts of blue foods to steer future production toward lower emissions and resource use -- a key part of the UN Sustainable Development Goals and ocean health.
"With demand for blue foods rising around the world, we need a better understanding of how the environmental pressures compare across this diverse group of foods so we can ensure we are eating not just nutritiously, but also sustainably," said Jessica A. Gephart, lead author and researcher at American University.
The paper also highlighted the potential of many subsectors, such as carp and milkfish, to improve their environmental performance through better farm management, efforts that reduce feed inputs and innovative technological interventions. Capture fisheries also have potential to reduce greenhouse gas emissions through improved management and optimizing gear types.
This research fills gaps in previous studies on the environmental stresses associated with food production, which often exclude blue foods. When blue foods are included, they are often lumped together, overlooking the vast range of species in the sector.
The study will ultimately allow businesses, certifiers, NGOs, consumers and other interested parties to make more informed decisions about how to support sustainable blue foods, while also highlighting the rich diversity and variety of the blue food market.

Abstract
This is a simple experiment that demonstrates the decomposition of sucrose by dissolving sucrose in hydrochloric acid. The products formed are optically active and their optical rotation can be determined by use of a polarimeter. This first order reaction follows a differential equation.
Introduction
The hydrolysis of sucrose can be considered a pseudo-first order reaction, in which the rate of change at any time is proportional to the concentration of sucrose. The rate of the reaction can be determined by the following equation,
(1)
Integration of equation (1),
, (2)
t, (3)
and therefore,
, (4)
where a is the initial concentration at time t, (a-x) equals the sucrose concentration, and k equals the fractional number of molecules decomposing per unit time.
The reaction rate constant k is calculated using the following equation:
, (5)
where (0) is the initial rotation of pure sucrose, (is the rotation at time (infinite time is the time when the reaction has gone to completion)and (t) is the rotation at some specific time t.
The k value is then used in the following equation to determine the concentration of sucrose at any given time,
, (6)
where c(t) is the calculated concentration for any given time t.
Equipment and Supplies
Hydrochloric acid (4 and 6 Molar), Sucrose, Sodium lamp, Polarimeter, Jacketed polarimeter tube, Volumetric flasks (100 mL), Graduated cylinders (25 mL), Constant temperature bath, Deionized H2O.
Procedure
The sodium lamp should be turned on at the beginning of the lab and positioned on the lab bench. The lamp takes 20-30 minutes to warm up, so this should be done first. Turn on the water bath and adjust the temperature appropriately, connecting a hose from the outlet of the constant temperature bath to one end of the jacketed polarimeter tube. Connect another hose to the other end of the tube so that the flow of the water can return to the constant temperature bath. A 100mL solution of 4 M HCl should be prepared. Place the flask in the constant temperature bath, securing it with a clamp and ring stand. A 100mL solution of 0.200 g/mL sucrose should be prepared. Place the flask in the constant temperature bath, securing it with a clamp and ring stand.
After the apparatus has had time to equilibrate, rinse the polarimeter tube first with deionized water, then with the sucrose solution. Fill the polarimeter tube with the sucrose solution and take an initial reading on the polarimeter. This will be taken as time = 0. Again, rinse the polarimeter tube with deionized water.
Remove the two flasks containing the 4M HCl and the sucrose solution from the constant temperature bath. Separately measure 25mL of each solution into two 50mL graduated cylinders. Mix the solutions in the graduated cylinders, at the same time starting the stopwatch. Mix the solution three or four times, then rinse the polarimeter tube with the mixture. Fill the polarimeter tube with the mixture, being sure to clear all bubbles from the tube. This can be done by slowly tilting the tube back and forth until all the bubbles float out.
Begin taking time readings after ten minutes for the 4 M solution, and continue taking readings every 10 minutes for 30 minutes. After 30 minutes begin taking 5 minute intervals readings as long as time permits. Begin taking readings for the 6M solution after 5 minutes and continue taking readings in 5 minute intervals as long as time permits. Leave the solution in the polarimeter at the end of lab and the final reading will be at time infinity, which should be approximately two days following the experiment.

Dapr actors overview
Overview of Dapr support for actors
The Dapr actors runtime provides support for virtual actors through following capabilities:
Actor method invocation
You can interact with Dapr to invoke the actor method by calling HTTP/gRPC endpoint
POST/GET/PUT/DELETE http://localhost:3500/v1.0/actors/<actorType>/<actorId>/method/<method>
You can provide any data for the actor method in the request body and the response for the request is in response body which is data from actor method call.
Refer api spec for more details.
Actor state management
Actors can save state reliably using state management capability.
You can interact with Dapr through HTTP/gRPC endpoints for state management.
To use actors, your state store must support multi-item transactions. This means your state store component must implement the TransactionalStore interface. The following state stores implement this interface:
 - Redis
 - MongoDB
 - PostgreSQL
 - SQL Server
 - Azure CosmosDB
Actor timers and reminders
Actors can schedule periodic work on themselves by registering either timers or reminders.
Actor timers
You can register a callback on actor to be executed based on a timer.
The Dapr actor runtime ensures that the callback methods respect the turn-based concurrency guarantees.This means that no other actor methods or timer/reminder callbacks will be in progress until this callback completes execution.
The next period of the timer starts after the callback completes execution. This implies that the timer is stopped while the callback is executing and is started when the callback finishes.
The Dapr actors runtime saves changes made to the actor's state when the callback finishes. If an error occurs in saving the state, that actor object is deactivated and a new instance will be activated.
All timers are stopped when the actor is deactivated as part of garbage collection. No timer callbacks are invoked after that. Also, the Dapr actors runtime does not retain any information about the timers that were running before deactivation. It is up to the actor to register any timers that it needs when it is reactivated in the future.
You can create a timer for an actor by calling the HTTP/gRPC request to Dapr.
POST/PUT http://localhost:3500/v1.0/actors/<actorType>/<actorId>/timers/<name>
The timer duetime and callback are specified in the request body. The due time represents when the timer will first fire after registration. The period represents how often the timer fires after that. A due time of 0 means to fire immediately. Negative due times and negative periods are invalid.
The following request body configures a timer with a dueTime of 9 seconds and a period of 3 seconds. This means it will first fire after 9 seconds, then every 3 seconds after that.
{
 "dueTime":"0h0m9s0ms",
 "period":"0h0m3s0ms"
}
The following request body configures a timer with a dueTime 0 seconds and a period of 3 seconds. This means it fires immediately after registration, then every 3 seconds after that.
{
 "dueTime":"0h0m0s0ms",
 "period":"0h0m3s0ms"
}
You can remove the actor timer by calling
DELETE http://localhost:3500/v1.0/actors/<actorType>/<actorId>/timers/<name>
Refer api spec for more details.
Actor reminders
Reminders are a mechanism to trigger persistent callbacks on an actor at specified times. Their functionality is similar to timers. But unlike timers, reminders are triggered under all circumstances until the actor explicitly unregisters them or the actor is explicitly deleted. Specifically, reminders are triggered across actor deactivations and failovers because the Dapr actors runtime persists the information about the actors' reminders using Dapr actor state provider.
You can create a persistent reminder for an actor by calling the Http/gRPC request to Dapr.
POST/PUT http://localhost:3500/v1.0/actors/<actorType>/<actorId>/reminders/<name>
The reminder duetime and callback can be specified in the request body. The due time represents when the reminder first fires after registration. The period represents how often the reminder will fire after that. A due time of 0 means to fire immediately. Negative due times and negative periods are invalid. To register a reminder that fires only once, set the period to an empty string.
The following request body configures a reminder with a dueTime 9 seconds and a period of 3 seconds. This means it will first fire after 9 seconds, then every 3 seconds after that.
{
 "dueTime":"0h0m9s0ms",
 "period":"0h0m3s0ms"
}
The following request body configures a reminder with a dueTime 0 seconds and a period of 3 seconds. This means it will fire immediately after registration, then every 3 seconds after that.
{
 "dueTime":"0h0m0s0ms",
 "period":"0h0m3s0ms"
}
The following request body configures a reminder with a dueTime 15 seconds and a period of empty string. This means it will first fire after 15 seconds, then never fire again.
{
 "dueTime":"0h0m15s0ms",
 "period":""
}
Retrieve actor reminder
You can retrieve the actor reminder by calling
GET http://localhost:3500/v1.0/actors/<actorType>/<actorId>/reminders/<name>
Remove the actor reminder
You can remove the actor reminder by calling
DELETE http://localhost:3500/v1.0/actors/<actorType>/<actorId>/reminders/<name>
Refer api spec for more details.

This activity can be used to discuss protective factors, resiliency, and self-esteem (finding beauty in the imperfections). By using a shell as a symbol of the body, nature can be used as a healing agent in therapy.
- (For religious teens and to use this activity for grief, pair with book: My Beautiful Broken Shell: Words of Hope to Refresh the Soul by Carol Hamblet Adams)
- Seashells (at least 3.5″, white, flat surfaces are best. Have multiple so client can choose)
- Primary paint colors (acrylic or water-color)
- Small paintbrushes
- Water (for cleaning brushes)
- Paint palette or paper plate
- Begin by asking, "How are our bodies like shells?"
Begin the dialogue with clients of how shells protect animals in nature the way our bodies protect ourselves.
"Shells are symbols of protection."
"Shells all used to have animals living in them."
"Some shells still have animals in them and they are in the sea."
"Other shells have washed up on the beach, like your shell," (point to shell in front of child). "Just like us, shells are all different and they've all been through different things."
"Even though some shells may have cracks or be worn down from the ocean, they are still strong and beautiful with stories to tell."
2. Next, have the client think of a happy memory, safe place, or relaxing scene.
This step is about how a child/teen can use the shell as a reminder of protection and embracing imperfections.
The shells can also be used as grounding items when a client is upset or needs comforting. You may choose to facilitate this step by first discussing and practicing mindfulness.
Instruct the client that they are free to paint any images or symbols that bring them peace and feelings of protection.
3. Discuss while painting.
While the client is painting, you can engage in a dialogue about what protection means to them and how they feel protected. Or for other clients, how even the imperfect shells can still be beautiful and have stories to tell.
"Since this shell represents safety and protection, you might consider keeping it in your safe space. Where are you planning on keeping your shell?"
"Who keeps you safe?" (Or for teens, "How do you keep yourself safe?")
"Which safe place are you choosing to paint?" etc.
Some kids may want to show their shell to their caregiver and explain what the shell means to him or her.
Example of using inspirational words and safe places on shells.
Have the Client think of a special place in his/her home to keep the shell as a daily reminder of protective factors, motivating words, and safe places.

Skinner presentation at GEOIDE 2009
The Geoweb Goes Wild: Developing A Participatory Geoweb Site As An Aid In Determining Rare Species Distribution, Randy Skinner, Yolanda Wiersma Erioderma pedicellatum (Ep), or boreal felt lichen, is critically endangered worldwide. Newfoundland currently has 95% of the known world population. The province of Newfoundland and Labrador has developed a five year management plan to assess the spatial distribution of Ep on the island. Surveys in the past have been largely opportunistic and focused on two hyperpopulated regions on the island. The provincial government has restricted use and development in regions where Ep has been found. To facilitate public awareness, as well as foster stewardship practices, our project will tap into the use of participatory Geoweb applications to gauge public awareness of the species in the province. Our project has a two‐fold focus. Web 2.0 widgets and applications will be used to develop a map-based interactive website so that users can pinpoint Ep sightings, add photos, or post forum info online. Web‐based aids will be provided to give the novice lichen hunter information and field tools to find and identify Ep. The ultimate goal is to determine the amount and degree of public input with Ep – a species that is still relatively unknown to the general public (i.e., uncharismatic), with a secondary objective of gathering more information on the spatial distribution of Ep. The second focus of our project will be to expand the Geoweb to allow for citizen‐derived observation about a suite of species, some of which will be more well‐known (charismatic) to the public. Public participation will be measured with each species via web statistics and user-generated input, noting the types of users, and the amount of participation and interest with each species. This project is part of a larger Phase IV Project (Team 41) on the Participatory Geoweb, which is being led by Dr. Renee Sieber of Mc Gill University.


text: Working memory neural networks, called Sustained Temporal Order REcurrent (STORE) models, encode the invariant temporal order of sequential events in short-term memory (STM). Inputs to the networks may be presented with widely differing growth rates, amplitudes, durations, and interstimulus intervals without altering the stored STM representation. The STORE temporal order code is designed to enable groupings of the stored events to be stably learned and remembered in real time, even as new events perturb the system. Such invariance and stability properties are needed in neural architectures which self-organize learned codes for variable-rate speech perception, sensorimotor planning, or three-dimensional (3-D) visual object recognition. Using such a working memory, a self-organizing architecture for invariant 3-D visual object recognition is described. The new model is based on the model of Seibert and Waxman (1990a), which builds a 3-D representation of an object from a temporally ordered sequence of its two-dimensional (2-D) aspect graphs. The new model, called an ARTSTORE model, consists of the following cascade of processing modules: Invariant Preprocessor → ART 2 → STORE Model → ART 2 → Outstar Network.


Home What is a Cloud Access Security Broker (CASB)?
What is a Cloud Access Security Broker (CASB)?
by Ahsan MuGhaL
What is a Cloud Access Security Broker (CASB)
What is a Cloud Access Security Broker (CASB)? Cybercriminals are leveraging technology to improve their malware and get past standard security policies deployed to cloud infrastructures. Therefore, businesses must integrate modern technology with their remote workplaces to improve network security and mitigate the risks of attacks.
What is a Cloud Access Security Broker (CASB)
One option is to deploy a Cloud Access Security Broker from an SSE Vendor to address risks in your cloud services. The goal is to enforce security policies through cloud-centric security capabilities that provide safe access to users. Since hybrid working is expanding, organizations must secure their remote and mobile employees while protecting the data and apps.
Understanding CASB
Cloud Access Security Broker is a cloud-based security policy enforcer that you can place between your cloud service and the consumers. You can use CASB to improve the enforceability of the security policies as your remote employees access cloud resources. Organizations prefer CASB as it can address security gaps in SaaS, PaaS, and IaaS environments.
Pillars of a CASB Solution
CASB is an integral part of enterprise security due to the following four pillars:
 1. Visibility
 Organizations require better visibility and control over their managed and unmanaged cloud services. Instead of an allow or block stance, CASB can allow users to access useful services while retaining governing access to activities and data within critical services.
 Even when CASB focuses on cloud security, it can help you control your cloud expenses. You can use it to discover all cloud services, generate a report regarding your cloud expenses, and detect redundancies in cloud functionalities.
 2. Compliance
 Organizations take compliance into consideration as they decide to move to the cloud. Regulatory agencies have designed compliance standards to ensure the safety and integrity of data. However, if an organization ignores these concerns, it can lead to costly data breaches.
 CASB ensures compliance with GDPR or any other regulatory agency as you use the cloud to facilitate your remote workforce. Therefore, it can assist in safeguarding your organization against data breaches while maintaining security policies defined by data regulators.
 3. Data security
 Organizations need to leverage sophisticated cloud DLP detection mechanisms like document fingerprinting and reduce the detection surface area to achieve accuracy. CASB solution shuttles suspected violations whenever it detects sensitive content in transit.
 You can use CASB to conduct deep threat observations to help your company identify and stop malware before it compromises your network security. Therefore, it acts as a gatekeeper to facilitate security.
 4. Threat protection
 Organizations must ensure that their employees are not introducing malware into the cloud resources. If your employee tries to upload an infected file across your external and internal network, CASB scans and remediates threats in real time. It can also detect and prevent unauthorized access to your cloud services, assisting in detecting compromised accounts.
What CASB Offers to Their Users
CASB contains unique security features that provide extensive control over your cloud applications. These features may include:
 - Cloud governance
 - Risk Assessment
 - Data Loss Prevention
 - Configuration auditing
 - Malware detection
 - Data encryption and key management
 - SSO and IAM integration
How a CASB Solution Works
Since a Cloud Access Security Blocker provides visibility and control over cloud infrastructures to meet security requirements through a three-step process:
 1. Discovery
 A CASB solution leverages auto-discovery to compile a list of third-party services and provides insights into who is utilizing them at a specified timestamp.
 2. Classification
 Once a CASB solution understands cloud usage, it determines the risks associated with each application by displaying the data and showing how the system shares it.
 3. Remediation
 After determining the relative risk of every application, the CASB uses the information to define security policies to secure the organization's data and restrict user access to meet security requirements.
How to deploy a CASB solution
CASB focuses on simplicity and ease of access; you can deploy it to your on-premises or cloud infrastructure. However, there are three CASB deployment models you can consider:
 1. API control
 Ideal for organizations that want comprehensive coverage to enhance visibility into threats and data stored on the cloud.
 2. Reverse proxy
 Ideal for organizations that want to allow access to devices that are located outside the network security perimeter.
 3. Forward proxy
 Ideal for organizations that want to boost their endpoint protection while managing a remote workforce.
CASB Use Cases
Here are three CASB use cases that can help you build to improve your network security
Governing usage
CASBs are known for their efficiency in detecting shadow IT behaviours and enhancing security across the organization. You can use CASB to govern how your employees use the organization's cloud resources through granular visibility and control. CASB also allows organizations to govern cloud usage by evaluating identities, services, activities, and applications.
You can also define policies according to service category or risk by defining enforcement actions like block, alert, encrypt, or quarantine. CASB makes it easier for your IT team to improve their internal monitoring and take action against users that do not follow security policies.
Securing data
CASB makes it easier to protect and prevent sensitive data loss across your organization's cloud services. You can use DLP policies to discover sensitive data on sanctioned or unsanctioned cloud services. You can use CASB to combat data loss through encryption, tokenization, or upload prevention.
Protecting yourself
You can use CASB to safeguard your organization's cloud against various threats like malware or ransomware. You can start setting up SSL-encrypted connections; you can use anomaly detection to detect unusual user behaviour on the cloud, while threat intelligence will help you detect compromised or at-risk accounts.
CASB also layers static and dynamic anti-malware detection algorithms combined with machine learning to detect and mitigate the risks of ransomware. Additionally, you can use the information generated by a CASB solution to improve your security infrastructure through numerous API integrations and workflows.
Conclusion
Organizations need stringent security policies to protect their data from malware and ransomware as they increase their remote working capabilities. The most effective approach is to deploy a CASB solution to improve the enforceability of your security policies on the cloud while monitoring the users to detect unusual behaviour.

Class 3 Calamity
Class 3 Calamity is a anime/manga concept
Edit this Page
The content below is entirely editable.
The Class 3 Calamity is a curse that haunts the 9th Grade students of Yomiyama North Middle School's Class 3.
Every year in Yomiyama North Middle School's 9th Grade Class 3, past records are mysteriously altered and an unidentifiable dead person joins class as an extra student. Changing rosters or class assignments fails to solve the issue and eventually, the dead student brings enough bad energy into the classroom resulting in a student and one of their family members dying every month.
No permanent cure has been found, however, one class was able to stop the calamity after it began by using currently unknown methods and acts involving a shrine. After years of death, the students and teachers of Class 3 found a preventive measure with a success rate nearing 50%. The students and teachers simply ignore one student and act as if they don't exist, which figuratively puts the class count back at a normal level, and prevents people from dying.
26 years before the start of the series, star student named Yomiyama Misaki tragically died in an accident. Unable to cope with or accept his death, his classmates, teachers, and students acted as if he was still an active member of the class. After graduation, they noticed that he still appeared in class photographs despite being dead.

The Tugu Peringatan Negara or more commonly referred to as Tugu Negara, is a complex located in Kuala Lumpur, adjacent to the Perdana Botanical Gardens.
The complex that houses the Tugu Negara also houses the Kuala Lumpur Cenotaph, which was originally erected by the British colonial administration.
The Cenotaph was originally located elsewhere but later transferred to the complex when works on the Tugu Negara complex began.
The Tugu Negara was designed by an Austrian, Felix de Weldon, who also designed the USMC (United States Marine Corp) War Memorial located in Virginia, USA. Works on the Tugu Negara began in 1963 and it was finally opened to the public in 1966.
The conceptualization of the Tugu Negara complex is to honour the approximate 11,000 dead from World War I (_PHONE_), World War II (_PHONE_) and The Malayan Emergency (_PHONE_).
The Tugu Negara was damaged in August 1975, when explosives were used by subversive elements to try to destroy the Tugu Negara. However, only two of the sculptures were damaged and restored soon afterwards.


Icelandic: tungl = moon [what is the etymology?]
Discussion in 'Nordic Languages' started by matakoweg, Nov 11, 2013.
 1. matakoweg Senior Member
 I just learned that moon is tungl in Icelandic while the mainland scandinavian languages have words related to moon: Danish måne.
 I was wondering where the Icelandic word come from.
 2. NoMoreMrIceGuy Senior Member
 Well, it's also máni. Google 'tungl' and 'wiktionary'. Tungl is from Proto-Germanic and has simply not survived in the other languages.
 3. Lugubert Senior Member
 You can find tungel in Swedish poetry or dialects, but it is almost extinct.

text: This paper develops an agent- and activity-based large-scale simulation model for Beijing, China (MATSim-Beijing) to explicitly simulate enroute travel, enroute refuelling and parking behaviours, as well as the associated vehicular energy consumption and emissions, based on MATSim (Multi-Agent Transport Simulation), which is a typical integrated activity-based model. In order to take into account heterogeneous parking and refuelling behaviours, the MATSim-Beijing model incorporates several Multinomial Logit (MNL) models to predict individual choices about the maximum acceptable times of walking from trip destination to parking lot, of diverting to a refuelling station and of queuing at a station, using the data collected in a paper-based questionnaire survey in Beijing. A Sensitivity Analysis (SA) -based calibration method was used to estimate the model parameters by searching for an optimal parameter combination with the objective of minimize the gap between simulated and observed traffic flow data, exhibiting a relatively good performance of decreasing the Mean Absolute Percentage Error (MAPE) by around 23%. Further, the calibrated model was used to investigate whether and how the population scaling and network simplification, which were two commonly used approaches to speeding up large-scale traffic simulations, might influence model accuracy and computing time. The results indicated that both approaches could to some extent influence model outputs, though they could significantly reduce computing time.

Ghosts in the Landscape: How Did the Village of Gainsthorpe Vanish?
There are many medieval villages in England that have disappeared throughout the years. However, one that remains more visible than most is the village of Gainsthorpe in Lincolnshire. When viewed from above, many elements of the village remain visible, such as the houses, barns and streets through earthworks in an unploughed field. Furthermore, Gainsthorpe was no small hamlet but a significant village, which can be traced from its earliest origins right through to its disappearance in the 17th century.

One of the earliest mentions of the village of Gainsthorpe is in the Domesday Book of 1086. This book was a great survey of England ordered by William the Conqueror after his conquest of the Anglo-Saxons. It sought to record how the land was occupied, by what sort of man and what stock was upon the land. The Domesday book shows how much dues and taxes should be due to the King each year. It is here where Gainsthorpe has its first mention, as the village known as "Gamelstorp".
It was originally owned in 1066 by a Saxon lord called Ulgar or Wulfgar. This name is associated with 21 other places in the Domesday book, though it should be noted that these may not all be the same person. By 1086, though, the possession of the land had been transferred to a Norman lord, Ivo Tallboys or Taillebois. This perhaps implies that during the taming of England by William, Ulgar/Wulfgar was killed.

What is important to note is that Ivo Taillebois was an important Norman nobleman in the reign of William the Conqueror, and his successor King William Rufus. He was in command of the Norman army at the siege of Ely in 1071, against English resistance. As a successful Norman lord, Ivo seems to have had his principal powerbase in Lincolnshire, whilst also gaining extensive lands throughout England. This may suggest that Gainsthrope was a reasonably thriving village as far back as 11th century England.
In 1208, Gameslestorp was again listed in a royal document detailing a list of legal land tenure agreements, the extent of which shows that the village had continued to grow. There was a minimum of 19 fields covering 108 acres described in the document, as well as a chapel, a windmill and a bridge.
Life in the Village
The manor building in the village was unlikely to have been very grand, despite it being where the wealthiest and most prosperous people of the village would have lived. It had a separate barn for livestock and was mostly constructed of timber in an A-frame construction. This would have been accompanied by a single longitudinal roof beam with walls made of woven branches/reeds combined with mud in the traditional method. Reeds would have been in plentiful supply thanks to the floodplains surrounding the village.
The village people themselves would likely have been of the lower class of citizen, principally laborers and farmers with few people who actually owned their own land. Essentially, they were "serfs" (indentured agricultural workers) who worked the land for the local lord.
Whilst the cause of decline of the village is unknown, the population of the village was potentially badly affected by the Black Death plague that ravaged England in the mid-14th century. The last mention we have of Gainsthorpe is in 1616 when the Duchy of Cornwall noted in a survey that "neither tofte, tenement or cottage" was left standing. In 1697, Abraham de la Pryme visited the site of Gainsthorpe in which he recorded the ruins of around 200 buildings. It is some of this that can still be seen today.
The Ruins Today
Much of the deserted village survives today as earthworks in grassed fields, through raised ridges and sunken hollows. From an aerial point of view, there are three/four roads visible as a hollow way through earthen banks on either side of a sunken track.
Nothing remains of the village but impressions on the landscape (Simon Tomson / CC BY-SA 2.0 )
There are the remains of about 25 buildings that can be seen laid out across 15 enclosures. Each enclosure is likely to have been occupied by a family or workers. There is a mixture of smaller buildings, which were houses, compared to the larger buildings which were likely barns. There are also faint traces of ridges in the North that suggest that the village also had open communal farms lying beyond the private enclosures.
Fascinatingly there are also quarry pits potentially dating from the 16th or 17th century that seem to respect the boundaries of these enclosures. This implies that the village may still have been occupied by at least a select few as late as these dates. There also exists an early 19th century farm, that perhaps suggests that the Gainsthorpe was never truly deserted.
So What Happened?
Whilst it will be impossible to make a definite cause on the disappearance of the village, there are some theories that can help explain why it experienced a decline. As previously mentioned, the Black Death of the 14th century may have been a significant issue for the town. The Black Death was a plague that swept across Europe and Asia in the 14th century. Arriving on boats, sailors and traded goods spread the disease far and wide causing the deaths of up to a third of the population, maybe as much as 25 million people across the world. Large parts of the population in England subsequently died. It is possible that this destabilized the village life in Gainsthorpe.
The Black Death devastated the population of Europe (Moynet / CC BY 4.0 )
Equally, as the archaeology shows, industry became much more popular throughout the 16th and 17th centuries and there was a shift from rural living to urban living. Gainsthorpe itself is situated near large cities that experienced rapid population growth in the age of industrialization, such as Leeds, Sheffield, Lincoln, and Scunthorpe. It may have just been that people moved away from the rural village in order to seek a living in the big bustling cities.
Lost to Time
The village itself can still be seen and reconstructed through the earthworks and ruins that remain. Whilst the village started with such a strong background and grew to a reasonable size, it unfortunately became victim, like many other medieval villages of England, to plague, pestilence and industrialization.

1994 Gmc Sonoma 2.2 Firing OrderYou could have noticed that your car or truck is firing order. This is due to the motors fire in a specific the order. Shape 4 demonstrates the firing order for your BMW S65, which abilities the 2012 M3 E90. Body 5 illustrates the firing series of each cylinder. Each and every cylinder fires following the after that 1 right after it provides reached 720/8=90°. Here's the actual way it is completed. Follow these steps to make sure your car performing efficiently. 1994 Gmc Sonoma 2.2 Firing Order.
1-2-3-4
It isn't always the situation, though in certain engines there is a firing order of 1-2-3-4 that may be employed. Different companies use various firing requests. In some instances firing purchases are absolutely unimportant. It's all depending on your generator manufacturer. There are, nonetheless, some versions to the rule. Discover more about these situations. Remember that firing orders placed have a showing! Below are a few of the most often happening circumstances.

Power cerebral vascular accidents, the longest of all the four strokes generates a range of tension. The thermal and mechanical tensions developed by an effective cerebrovascular event could affect an generator. It is crucial to ensure that these 2 kinds of stress don't take place throughout the exact cylinder. In multi-cylinder motors the firing buy is really important. Before the other and the engine won't function effectively, in the event that one engine fires first.
As an example the first tube must be fired before the second one, given that firing the next one right after the first could result in abnormal vibration as well as heat. The next cylinder would be to stick to the firstone, since it will be able to begin the energy cerebrovascular event subsequent 180 degrees of crankshaft change. 4. Your fourth one is able to go. Then a after that. Your order for which you fireplace is vital on the engine's sleek performance. The pattern of pistons will determine exactly how much energy every single piston makes.
1-8-4-3-6-5-7-2
There are a variety of firing buy options available for level-airplane cranks. The cylinders to complete opposite aspects of the main cylinder are fired within the same get these folks were changed. The firing order is popularized by Cosworth. The Cosworth 2.4-liter V8 engine was renowned for its capability to get to 22,000 rpm on Method 1. Formula 1 keep track of. The firing sequence Cosworth utilized was really a variance of 1-5-2-6-4-7-3. It had been used by Kaase and later on utilized to create Solution One. The firing sequence Cosworth used was revised from the late nineties to make up the higher torsional vibrations of their motor.
Whats The Firing Order For A 1994 GMC Sonoma
The first firing order is utilized on conventional American V8 motors, typically. The first V8 motors, for example the ones from Olds V8 and Buick Nailhead used this firing order. Cadillac and Ford used three firing orders placed in 1960s to the LS motors. While they're less preferred at present, the firing sequence was preferred on specific types. The firing pattern for the Chevy 350 is 1-8-4-3-6-7-2.
The firing get is vital to the engine's power productivity, generator audio, and vibrations. The firing order is vital for the design of the crankshaft as well as its functionality. The numbering of cylinders is generally elevated from top to rear of any engine nevertheless it isn't always the scenario. In V8 engines an order of firing will likely be based on crankshaft's place and the cylinders. As an illustration this is basically the scenario that variety 57, and 7 cylinders can be found at the back in the engine block.
1-3-4-2
There are 2 techniques the 1-3-4-2 Firing Buy might be used, such as to begin each and every tube with the series of strokes. The other option is regular 1-3-4-2. This is actually the get wherein the cylinders begin firing in a race engine. The 2nd way is the reverse. The contrary on this layout is definitely the lender-to banking institution combustion cycle which induces a large volume in motor shake. Although it's almost never used Godbold has read about 2 or 3 NASCAR squads who definitely have tried out this method.
Chevrolet S 10 Questions What Is The Firing Order For The 87 2 8 S10
When making an motor when building an engine, it is very important to contemplate the firing sequence for each tube. Within an V-design motor the cylinders A1-B1 are living about the outboard part. Cylinders R1 and L1 might be on the right and left banking companies and the remaining banking institution, respectively. Two-tube motors operate in a purchase order that is a lot like the V-shape motor and have the ability to be fired in the same series or in a pattern.
The firing get from the a number of-cylinder engine is 3-4-2. Although the six-cylinder generator has distinct firing orders placed. The No. 1 tube is fired each and every 120 degrees of crankshaft rotation The the cylinders no. 2 and 3 flame each 180 diplomas. If you are changing a 1-3-4-2 Fire Order, you'll likely end up removing the benefits that were inherent in the design.

This study investigated the presence of viable Mycobacterium avium ssp. paratuberculosis (MAP) in pasteurized milk produced by Italian industrial dairy plants to verify the prediction of a previously performed risk assessment. The study analyzed 160 one-liter bottles of pasteurized milk from 2 dairy plants located in 2 different regions. Traditional cultural protocols were applied to 500mL of pasteurized milk for each sample. The investigation focused also on the pasteurization parameters and data on the microbiological characteristics of raw milk (total bacterial count) and pasteurized milk (Enterobacteriaceae and Listeria monocytogenes). No sample was positive for MAP, the pasteurization parameters complied with European Union legislation, and the microbiological analysis of raw and pasteurized milk showed good microbiological quality. The results show that a 7-log (or >7) reduction could be a plausible value for commercial pasteurization. The combination of hygiene practices at farm level and commercial pasteurization yield very low or absent levels of MAP contamination in pasteurized milk, suggesting that pasteurized milk is not a significant source of human exposure to MAP in the dairies investigated.
Keywords: Mycobacterium avium ssp. paratuberculosis; pasteurized milk.

Youngsters at Ferring Primary in Sea Lane have been busy growing tropical fruit tree species, identical to those grown as part of a special project in Malawi, which grows a tree for every ton of aluminium drinks cans recycled in the UK.
The children held a group fruit-tasting session to discover the flavour of fruits grown in Malawi and then used the seeds to plant their own trees, including avocado and mango.
A year on, the children's trees are thriving and they have collected an excellent 40 kilos of clean aluminium foil so far which will be counted towards growing trees in Malawi.
Zo Walker, a teaching assistant, said: "The whole school community is contributing to our foil collection and the pupils have enjoyed watching the plants developing in the classroom.
"Money from the recycling of the foil is passed to the Guide Dogs for the Blind."

CheckInfo, for example:
TaskInfo task = [...];
HealthCheck healthCheck;
healthCheck.set_type(HealthCheck::HTTP);
healthCheck.mutable_http()->set_port(8080);
healthCheck.mutable_http()->set_scheme("http");
healthCheck.mutable_http()->set_path("/health");
task.mutable_health_check()->CopyFrom(healthCheck);
TCP Health Checks
TCP health checks are described by the HealthCheck.TCPCheckInfo protobuf, which has a single port field, which must specify an actual port the task is listening on, not a mapped one. The task is probed using Mesos' mesos-tcp-connect command, which tries to establish a TCP connection to <host>:port. Note that <host> is currently not configurable and is set automatically to 127.0.0.1 (see limitations), hence the health checked task must listen on the loopback interface along with any other routeable interface it might be listening on. Field port must specify an actual port the task is listening on, not a mapped one.
The health check is considered successful if the connection can be established.
If necessary, executors enter the task's network namespace prior to launching the mesos-tcp-connect command.
To specify a TCP health check, set type to HealthCheck::TCP and populate TCPCheckInfo, for example:
TaskInfo task = [...];
HealthCheck healthCheck;
healthCheck.set_type(HealthCheck::TCP);
healthCheck.mutable_tcp()->set_port(8080);
task.mutable_health_check()->CopyFrom(healthCheck);
Common options
The HealthCheck protobuf contains common options which regulate how a health check must be performed and interpreted by an executor:
 - delay_seconds is the amount of time to wait until starting health checking the task.
 - interval_seconds is the interval between health checks.
 - timeout_seconds is the amount of time to wait for the health check to complete. After this timeout, the health check is aborted and treated as a failure.
 - consecutive_failures is the number of consecutive failures until the task is killed by the executor.
 - grace_period_seconds is the amount of time after the task is launched during which health check failures are ignored. Once a health check succeeds for the first time, the grace period does not apply anymore. Note that it includes delay_seconds, i.e., setting grace_period_seconds < delay_seconds has no effect.
NOTE: Since each time a health check is performed a helper command is launched (see limitations), setting timeout_seconds to a small value, e.g., <5s, may lead to intermittent failures.
As an example, the code below specifies a task which is a Docker container with a simple HTTP server listening on port 8080 and an HTTP health check that should be performed every 5 seconds starting from the task launch and allows consecutive failures during the first 15 seconds and response time under 1 second.
TaskInfo task = createTask(...);
// Use Netcat to emulate an HTTP server.
const string command =
 "nc -lk -p 8080 -e echo -e \"HTTP/1.1 200 OK\r\nContent-Length: 0\r\n\"";
task.mutable_command()->set_value(command)
Image image;
image.set_type(Image::DOCKER);
image.mutable_docker()->set_name("alpine");
ContainerInfo* container = task.mutable_container();
container->set_type(ContainerInfo::MESOS);
container->mutable_mesos()->mutable_image()->CopyFrom(image);
// Set 'grace_period_seconds' here because it takes
// some time to launch Netcat to serve requests.
HealthCheck healthCheck;
healthCheck.set_type(HealthCheck::HTTP);
healthCheck.mutable_http()->set_port(8080);
healthCheck.set_delay_seconds(0);
healthCheck.set_interval_seconds(5);
healthCheck.set_timeout_seconds(1);
healthCheck.set_grace_period_seconds(15);
task.mutable_health_check()->CopyFrom(healthCheck);
Under the Hood
All built-in executors rely on the checker library, which lives in "src/checks". An executor creates an instance of the Checker or HealthChecker class per task and passes the check or health check definition together with extra parameters. In return, the library notifies the executor of changes in the task's check or health status. For health checks, the definition is converted to the check definition before performing the check, and the check result is interpreted according to the health check definition.
The library depends on curl for HTTP(S) checks and mesos-tcp-connect for TCP checks (the latter is a simple command bundled with Mesos).
One of the most non-trivial things the library takes care of is entering the appropriate task's namespaces (mnt, net) on Linux agents. To perform a command check, the checker must be in the same mount namespace as the checked process; this is achieved by either calling docker run for the check command in case of docker containerizer or by explicitly calling setns() for mnt namespace in case of mesos containerizer (see containerization in Mesos). To perform an HTTP(S) or TCP check, the most reliable solution is to share the same network namespace with the checked process; in case of docker containerizer setns() for net namespace is explicitly called, while mesos containerizer guarantees an executor and its tasks are in the same network namespace.
NOTE: Custom executors may or may not use this library. Please consult the respective framework's documentation.
Regardless of executor, all checks and health checks consume resources from the task's resource allocation. Hence it is a good idea to add some extra resources, e.g., 0.05 cpu and 32MB mem, to the task definition if a Mesos-native check and/or health check is specified.
Windows Implementation
On Windows, the implementation differs between the mesos containerizer and docker containerizer. The mesos containerizer does not provide network or mount namespace isolation, so curl, mesos-tcp-connect or the command health check simply run as regular processes on the host. In constrast, the docker containerizer provides network and mount isolation. For the command health check, the command enters the container's namespace through docker exec. For the network health checks, the docker executor launches a container with the mesos/windows-health-check image and enters the original container's network namespace through the --network=container:<ID> parameter in docker run.
Current Limitations and Caveats
 - Docker executor does not support generalized checks (see MESOS-7250).
 - HTTPS checks are not supported, though HTTPS health checks are (see MESOS-7356).
 - Due to the short-polling nature of a check, some task state transitions may be missed. For example, if the task transitions are Init [111]Join [418]Ready [200], the observed HTTP status codes in check statuses may be 111200.
 - Due to its short-polling nature, a check whose state oscillates repeatedly may lead to scalability issues due to a high volume of task status updates.
 - When a task becomes unhealthy, it is deemed to be killed after HealthCheck.consecutive_failures failures. This decision is taken locally by an executor, there is no way for a scheduler to intervene and react differently. A workaround is to set HealthCheck.consecutive_failures to some large value so that the scheduler can react. One possible solution is to introduce a "global" policy for handling unhealthy tasks (see MESOS-6171).
 - HTTP(S) and TCP health checks use 127.0.0.1 as target IP. As a result, if tasks want to support HTTP or TCP health checks, they should listen on the loopback interface in addition to whatever interface they require (see MESOS-6517).
 - HTTP(S) health checks rely on the curl command. A health check is considered failed if the required command is not available.
 - Windows HTTP(S) and TCP Docker health checks should ideally have the mesos/windows-health-check image pulled beforehand. Otherwise, Docker will attempt to pull the image during the health check, which will count towards the health check timeout.

When you are looking to "manage" deer, it is very helpful to collect information that clues you into understanding deer numbers in your area and their impact on their habitat. Trail cameras can help estimate numbers of deer, and browse impact studies can help determine the impact they are having on their food source. If deer are overeating their food source, even without knowing "how many" deer there are, you should know that more does need to be harvested for the sake of the health of the herd. The deer browse impact survey is a great tool that gets out into the woods and helps you evaluate the level of impact deer are having. Below we cover some of the basics, however, there are links to articles with more details at the end of this blog.
In an ideal situation, you would plan to run the survey on around 500 acres of forest after snowmelt, but before green-up. But… who has 500 acres of contiguous forest? Chances are if you live in Southern Michigan, you don't. If you live in Northern Michigan, you may, but chances are you don't own all of it. For the sake of conversation, we will use 500 acres to describe the process, but feel free to tweak the process for your situation. For example, on my 12 acres (long and skinny), I simply ran two transects along the long borders of my land.
If you have 500 acres, you would want to have 5 lines (transects) each 1,000 feet apart and 1 mile long. (If you were so lucky to have 1,000 acres, you would have two sets of 5 transects.) Along each mile-long transect, you want to stop every 100 feet (so that you have about 52 plots/line) and evaluate the browse impact within a 4 foot radius at each plot.
Suggested Equipment: Briar proof clothing, clipboard and pencil, data form (see below), compass (traditional, not your smartphone) and a walking stick with 4 feet marked on it
- Picking transect locations: Ideally, the transects should cover multiple cover types and be as straight as possible. Using an aerial map to plan your transects is recommended. You will want to avoid swamps, ponds, etc. Work with your neighbors if possible.
- Team up with crews of at least 2 people.
- Once you have your equipment and your team, you want to plan a day after the snow has melted, but before the leaves have popped out. At the beginning of one of your lines, make your first plot evaluation. Look at the plants within a 4 foot radius and determine the browse impact of the plants between 6 inches off the ground and 6 feet off the ground (the height deer eat at). Document how heavily the stems are browsed on your data form (link below). Once you have documented your observations, count about 30 paces, or 100 feet. Then evaluate the next plot.
- As you are going along your transect, keep your eyes open for pellet piles. Tally how many you see. Once you have collected all the data, there is an equation on the form that will allow you to estimate the deer density on the property based on the pellet numbers you have.

I'm using an iterator in ModelBuilder (1) to merge files, using a feedback loop (2). The output file is named "Output_%n%.txt", (3), so each file is unique.
Now, I'm merging a fair number of files, so I'm trying to speed the process up. Since I don't care about the interim files, I can write them out to in_memory. But I would like to save the final file, viz: "Output_167.txt" to C:\myfile rather than in_memory.

This question came from our discussion, support, and feature requests site for cartographers, geographers and GIS professionals.
 - How about you write them all to in_memory as you are then the next step is to write out the final dataset, you know what %n% is so it should be fairly easy to export out. I am surprised that the in_memory workspace allows that naming convention. – Hornbydd Oct 24 '14 at 7:51
 - @horbbydd. That does work, but I'm trying to generalize the tool in such a way that I can apply it to multiple tables of unknown length. I could use a count function or table properties to get the number of rows, and then export when x=%n%, but doing so would require using a nested model, so it didn't redo the count multiple times. – Mox Oct 27 '14 at 19:59

@Hornbydd Months later, I finally understand your reply. I could not think how to get n, realized that for this specific purpose, I'm using a FOR loop, with a model parameter. It will take some text slicing, but I can extract the n from %n%. For cases where I am not, such as iterating over rows in a data-set, I can use max(ID) to get the iteration count.
