The Climate Crisis talk for Cheshire WI meetings
As Climate Change Ambassadors of the Cheshire Federation of WIs we are offering short illustrated talks on how all of us can help to slow down global warming, and also adapt to it.
We provide a choice of modular topics which form a cohesive presentation event. Timings can be adjusted to suit the individual WI or Group. This event will answer some of the questions that WI members have about the changing climate. It will provide WI members with actions they can take on a local, personal level to help mitigate climate change by reducing their carbon footprint and to prepare for coping with extremes of climate.
There are two core modules that form the framework of every presentation which together take around 20 minutes. These are:-
- An introduction on What is Climate Change. An overview of the science behind climate change and the effects of a warmer climate.
- The WI Pledge. We offer members the opportunity to pledge to make a simple change in their lifestyle choices. Our presentations and pledge cards will provide ideas on how they can mitigate their carbon footprint, everything from a meat free day a week to switching to green electricity. We will also ask the members to suggest other actions they think would reduce carbon emissions to mitigate climate change. We then ask them to select one positive action and pledge to do it by filling in the pledge card.
We also ask the members to write their pledge on a post-it note that we can take away so we can monitor how many pledges we are getting across the Federation and which ones are the most popular. We do not collect anybody's name.
In addition we offer a choice of five climate change modules for WIs to choose from and also a short quiz. These ten minute talks can be added to the core presentation to provide a longer talk. We look at specific areas of daily life and help members to learn how climate change will affect these areas. We will suggest actions they can take to mitigate their carbon footprints and to adapt to the effects of climate change.
- Gardening in a changing climate. A presentation covering some of the ways members can reduce their gardening carbon footprint and adapt their gardens to cope better with a more extreme climate. Including steps they can take to support and encourage the wildlife in their garden that is now so adversely affected by many environmental challenges.
- Trees. These natural carbon sinks could save us if we plant enough of them. Find out how they help, why we need them and how to get them planted.
- Steps towards an eco home . A look at choices members can make in their own homes that will reduce their carbon footprint by simple changes in energy consumption.
- Travelling with Climate Change in mind. From riding your bike to choosing a holiday there are many ways the changing climate could make a difference to why and how you travel. We will recommend choices that help the planet by reducing our dependency on fossil fuels.
- Food and climate change. How we produce food, how we prepare it and what we eat are a massive part of the carbon footprint of humanity. Learn simple changes that make a big difference
- The Footprint Quiz. A simple quiz on ten aspects of everyday life such as eating a steak, washing a load of clothes and driving ten miles. The audience will be asked to select one of three possible values of carbon emission for each activity. This can be done as audience participation or as a printed handout for teams.
A free presentation for Cheshire WI meetings
There is no charge for the presentation, but we would appreciate a contribution to travel costs.

Procedural Storytelling in Game Design
Procedural storytelling has become an increasingly important and popular aspect of video game design in recent years.
This type of story-driven gameplay relies on algorithms and code to generate narrative elements such as characters, environments, and plot events in response to the player's actions.
By harnessing the unique creative potential of computer-based media, procedural storytelling allows designers to create deeply immersive experiences that seem almost alive.
What's more, this approach often induces a specific kind of delightful 'aha!' moment for players as they begin to grasp how their own impulsive, seemingly chaotic actions are actually shaping the unfolding story of the game.
Whether it's exploring a beautifully realized fantasy world or unraveling the mysteries of an intricate sci-fi mystery, procedural storytelling has something exciting to offer every kind of gamer out there. So proceed with delight – the possibilities are endless!
Game design storytelling
Game design is an incredibly complex art form, requiring the coordinated efforts of a diverse team of professionals.
In order to create a truly immersive and captivating experience, every member of the development team must contribute their own unique skills and talents.
From the game designers who plan the overall structure of the story to the coders who implement the mechanics that bring it to life, each member of the team plays an essential role in making the player's journey a memorable one.
By understanding the contributions of each individual member of the development team, we can begin to appreciate the true complexity of video game storytelling.
Video game storytelling narrative techniques
Video games are a medium like no other, with the ability to offer not just engaging interactive gameplay but also an immersive and engaging story. Video games can use a wide variety of different techniques beyond those common in other media, such as sound design, lighting, and camera movement, to create unique storytelling experiences.
For example, certain sounds or cues may trigger particular responses from the player, adding an extra level of unpredictability to a game's narrative. Similarly, a dynamic and vibrant lighting scheme can help to create a sense of urgency or tension thanks to dramatic changes in color and brightness.
At their best, video games offer truly unique and engaging storytelling experiences that cannot be found elsewhere. Whether it is through familiarity with the genre or the no-limit nature of the video game medium itself, video games have endless potential for creating gripping narratives that suck players in and keep them wanting more.
So if you're looking for something new and exciting to experience on your next gaming adventure, then strap yourself in and let the journey begin – with video games and their many powerful storytelling tools at your fingertips, there's no telling where the story will take you next!
Video game storytelling narrative designer
The quality of the narrative has become one of the most crucial features ahead of graphics quality and even gameplay of today's most successful video games.
The challenge is clear: to create multidimensional video games with interactive and immersive storylines, where color design choices and subtle interactions are just as important to the storyline as dialogue or setting.
And rising to meet the challenge, at the new frontier of immersive storytelling, is an entirely new breed of a storyteller: the narrative designer. Narrative designers are responsible for creating the story and characters for a video game, as well as working with the game designers to ensure that the gameplay elements support and enhance the story.
They must be able to think creatively to come up with original ideas, but also have the technical skills to bring those ideas to life in a video game format. In addition, they need to be able to work within the constraints of the medium, such as creating branching storylines that give players choices without compromising the overall plot.
Rising to meet the challenge of creating immersive, compelling stories for video games is a new breed of a storyteller: the narrative designer. With their creative vision and technical skills, narrative designers are shaping the future of video game storytelling.

Abstract
Possible differences in the diet or metabolism of sympatric finback and humpback whales in the Gulf of St. Lawrence were investigated through analysis of their blubber fatty acids. Free-ranging finback (Balaenoptera physalus, n=19) and humpback (Megaptera novaeangliae, n=10) whales were sampled through biopsy during summer 1991. The two species differed in the chemical composition and stable carbon isotope distribution of fatty acids extracted from their outermost blubber layer. Finback blubber was slightly but significantly richer in its relative proportions of 12:0, 13:0, i14:0, 17:0, 18:1 n9, 18:1 n7, and 20:0 (probability of difference ≥99%), 18:2 n6, 18:0, and 19:0 (probability ≥95%), and 16:1 n5 and 16:0 (≥90%). The stable isotope ratio of finback total fatty acids averaged-25.5±0.4%. Humpbacks contained relatively more i16:0, 18:1 n5, 20:5 n3, and 22:6 n3 (probability ≥99%), 16:1 n7, i18:0, 20:4 n6, and 22:5 n3 (≥95%), and 20:4 n3 (>90%). Their fatty acid δ 13 averaged -25.8±0.5% (different from finbacks with a probability of 95%). There was no significant difference between the two species in the relative proportions of 14:1, 14:0, i15:0, a15:0, 15:0, i17:0, a17:0, 17:1, 20:1 n9, 20:1 n7, 22:1 n11, or 22:1 n9, which together made up one-third of total fatty acids. We used principal component and cluster analyses to integrate and visualize the differences in the chemometric data sets. The chemical and isotopic differences found in the present study are consistent with a slightly lower trophic position for humpbacks compared to finbacks in the Gulf of St. Lawrence, reflecting a difference in long-term, average diet.

Jean Ritchie, folk singer and UK graduate, being presented the school's first Founders Day award by President Donovan.
According to the April 4, 1944 Board of Trustees Minutes President Donovan recommend that the University celebrate the day of its founding. "Some time ago I requested Professor E. L. Gillis, who is probably as familiar with the history of the University as any man connected with it, to study various dates that might be considered as an appropriate date on which to celebrate a Founders Day Program. After considerable research, Professor Gillis has suggested that February 22 would be a very appropriate time for such a celebration. It was on February 22, 1865, that the General Assembly of Kentucky approved a bill establishing an Agricultural and Mechanical College in connection with Kentucky University (now Transylvania). Therefore, February 22, 1865 is the date on which the University of Kentucky actually came into existence as a state institution."

How does Pure hot yoga work?
By the tourniquet effect: stretching, balancing (using gravity), and creating pressure all at the same time. The blood supply in arteries and veins is being cut off, creating pressure. When released, a lock gate effect is created, causing blood to rush through veins and arteries, flushing them out. Also, pressure is applied to the heart by its relative position to the rest of the body.

The purpose of this paper is to argue for clarity of methodology in social science simulation. Simulation is now at a stage in the social sciences where it is important to be clear why simulation should be used and what it is intended to achieve. The paper goes on to discuss a particularly important source of opposition to simulation in the social sciences which arises from perceived threats to the orthodox hard-core. This is illustrated by way of a couple of case studies. The paper then goes on to discuss defences to standard criticisms of simulation and the various positive reasons for using simulation in preference to other methods of theorising in particular situations.

One of the most frequent questions we are asked is if our honey is infused or flavored with other ingredients to give it its distinct flavor. The answer is ABSOLUTELY NOT. Eulogia honey is a raw and natural honey, neither artificially flavored nor infused with other ingredients.
The way it works is like this: Our beehives are placed in specific locations with miles of nothing but abundant blossoming flowers. Since most of our honey is monofloral, our beekeepers carefully place beehives in an area where the bees have access to only one type of flower. The bees then travel freely about three miles on average from their hive and suck the surrounding flower nectar as their food and energy source. The nectar they consume remains in their stomachs as they make their way back to the hive. While in the bee's stomach, this nectar mixes with bee proteins and enzymes, naturally producing honey which is then regurgitated into the beeswax comb. Eulogia honey is carefully collected directly from the hive and packaged without being exposed to high heat, pasteurization or processing in order to preserve its natural abundance of vitamins and minerals.
Flavor and color variations in honey depend on the flora which the bees feed on as well as local climate. This is why, for example, Eulogia Sage Blossom honey will not have the same taste, color or viscosity as a sage honey produced in California. It is a known fact that honey absorbs moisture directly from the air and therefore the amount of water in a honey is dependent on relative humidity in the air. Our honey has a thicker consistency than most honey due to Greece's dry climate and minimal amount of humidity.

Land Use / Land Cover Change
| The following are some of the USGCRP's major accomplishments
related to Land
Use / Land Cover Change during Fiscal Year 2002:
National Land Cover Database:
A 1992 National Land Cover Database (NLCD) was completed, validated to determine accuracy, and released via a seamless Internet map server. The development of the NLCD was supported by four USGCRP agencies. The NLCD was produced using 1992 Landsat Thematic Mapper satellite data; it included the categorization of 21 general land cover types, spanned the 48 contiguous states, and had 30- meter spatial resolution. The dataset was designed to support a wide range of environmental assessments, including analysis of the rates of land cover change, impacts of land cover change on water quality, and the evaluation of ecosystem form and function. Its national and regional applications include watershed management, environmental inventories, transportation modeling, fire risk assessment, and land management. Access to the data is through the USGS Land Cover Characterization Program.
Land Use/Land Cover Change in U.S. Ecological Regions:
An analysis of land-use and land-cover change in nine eastern U.S. ecological regions has been completed. In the first phase of a study to document land-use and land-cover change for five periods from 1973 to 2000 (1973, 1980, 1986, 1992, and 2000) for 84 U.S. ecological regions, Landsat satellite data were interpreted to determine the contemporary rates of change. During the nearly 30-year period, land use/land cover changed over approximately 20 percent of the area of in the Mid-Atlantic Coastal Plain and Southeastern Plain, due to the rapid, cyclic harvesting and replanting of forests. The adjacent Piedmont region also showed substantial change in forest cover. Urbanization was the dominant conversion in the northern Piedmont and Atlantic Coast Pine Barrens. The two Appalachian regions studied (Blue Ridge and North Central Appalachia) experienced comparatively low levels of change, with the primary transformations being urban development and forest conversion, respectively. The early results of this national study provided evidence of the distinctive regional character and variation in the rates and characteristics of land-use and land-cover change. (See Figure 7.1.)
Land Use/Land Cover Change and Changes in Soil Carbon and Nitrogen:
Recent satellite and ground based studies in the southern United States indicate that woody encroachment into grasslands can significantly alter biogeochemical cycling in arid to semi-arid ecosystems. Specifically, shifts from grasslands to shrublands and forestland in northern Texas have increased substantially during the past 70 years, contributing to increases in plant and soil carbon and nitrogen stocks in the region. These changes have occurred primarily as the result of abandonment of agricultural and pasture lands as well as changing fire and grazing practices. Together, these changes have implications for future land management.
Fire Disturbance and Forest Carbon Storage:
Increasing atmospheric CO2, climatic variation, and fire disturbance all play roles in the historical carbon cycle dynamics of Alaska. Analyses of the distribution of the ages of tree stands in Alaska indicate that fire has likely become less frequent since 1950, compared to the first half of the 20th Century. Quantitative results from application of the Terrestrial Ecosystem Model (TEM) indicate that the key factor responsible for the substantial carbon storage in Alaska during the 1980s was regrowth under a less frequent fire regime. In the context of the overall U.S. carbon budget, the analyses with TEM indicate that Alaska is likely to be an important region of carbon storage. The applications of mechanistic models, such as TEM, represent complementary tools to atmospheric analysis, with the potential to provide information on the quantity of changes in carbon storage at finer spatial scales, and also to provide information on factors responsible for changes in carbon storage. This information may be useful in evaluating policy options related to the U.S. carbon budget.
Forest Cover Increase and Carbon Sequestration:
Forest cover increases averaging 7 percent per decade between about 1970 and 1990 have been found in analyses of the U.S. Upper Midwest. Data from 136 representative study sites were collected using satellite data, aerial photography, and field data, combined with regional Geographic Information System-based models. The results indicate increased carbon sequestration, because forest cover is primarily replacing pastures and croplands. Forest regrowth and planting in the temperate forests of the Northern hemisphere due to land-use change may account for some of the "missing sink" in carbon budgets. The observed increase in the Upper Midwest resulted primarily from the abandonment of marginal agricultural lands as the farm economy in the region has declined. A significant decade-scale lag effect was observed between abandonment and regrowth. A countervailing trend is extensive dispersed rural development in the region, driven by demand for recreation and retirement destinations as well as for seasonal homes. This work highlights, and also raises questions about, the dependence of land-use change and consequent carbon sequestration on agriculture policies, infrastructure investments, and regional and local planning efforts. (See Figure 7.2)
7.2. Forest cover increase and abandonment of marginal
agricultural lands in the Upper Midwest
Land Use/Land Cover Change and Native Species Viability:
Analyses of Landsat imagery, along with aerial photographs, indicate that conifer forests expanded by more than 7 percent in the Greater Yellowstone Ecosystem during 1975-95.The major land-cover changes were a 347 percent increase in urban area and a 400 percent increase in rural residences. A key finding is that hot spots for native species overlap with intensive land use in the same small portion of the landscape. A critical consequence is that development on private lands threatens the viability of some native species in Yellowstone National Park and other nature reserves. Another key finding is that human population and economic growth are associated with changes in ecosystem attributes; rapid change has important implications for carbon storage and biodiversity. Information from this study can be used to better manage the urban-park interface to ensure conservation of natural resources while encouraging regional economic activity.

Rails ActiveRecord PostgreSQL Foreign Keys and Data Integrity

Ruby on Rails data integrity represented by wood Photo by Simon Stankowski on Unsplash
Most Ruby developers work with Rails and Active Record for PostgreSQL database interactions. It provides a ton of magic and is simple to start with. Data integrity problems start creeping up once the code base and database structure gets older. In this tutorial, I will describe a couple of techniques for ensuring data integrity and validation in Ruby on Rails web apps. We'll cover adding foreign keys, database level validations and more.
Your Rails app data integrity can get out of sync for various reasons. Active Record approach to database modeling encourages a developer to keep most of the logic in the app layer Ruby code. Let's list some example actions that could corrupt your data state:
 - update object attribute using update_column method
 - delete a parent object of an association with delete
 - persist an object with save(validate: false)
 - change model validations without updating the current data
 - concurrent data updates bypassing uniqueness validations
Rails is not making it easy. Data in an invalid state might bite you very hard eg. when running a migration that would raise an exception in case of a validation error.
How to "Brute-force" detect validation errors
I want to share a dirty hack I've recently come up with. It might seem obvious and resorting to it look like a signal of a very poor codebase quality but bear with me.
It's a Sidekiq worker class:
class ModelDataIntegrityCheckerJob
 include Sidekiq::Worker
 sidekiq_options retry: false
 def perform(klass_name)
 klass = klass_name.constantize
 invalid_objects = []
 klass.find_each do |object|
 unless object.valid?
 invalid_objects << [object.id, object.errors.full_messages]
 end
 end
 if invalid_objects.present?
 raise "Invalid state for #{klass} objects: #{invalid_objects}"
 end
 invalid_objects
 end
end
You can use it like that:
 ModelDataIntegrityCheckerJob.perform_async(User.name)
 ModelDataIntegrityCheckerJob.perform_async(Course.name)
It will raise a runtime error with IDs of invalid objects from a given class. In turn you can fix them or corresponding validations manually. If your dataset is big, you might want to run those jobs at night or scope the range of objects validated.
It would seem like the brute force approach is not a perfect solution to validating data integrity. But can you with 100% certainty tell that every single one of your ActiveRecord objects is currently valid?
I sometimes run those brute force checks before doing more complex database migrations to ensure that some sneaky invalid objects won't blow up during the process. I like to think of them as a periodical data validation health checks.
Let's list a couple of more elegant techniques you can use to keep your app's data in a more integrated and valid state.
NOT NULL constraints
"Non-binary logic" is a frequent guest in Ruby on Rails apps. I've seen many nasty bugs caused by a simple fact that:
false != nil
Sometimes the business logic itself was dependent on the fact nil in a database meant something else than false… (╯°□°）╯︵ ┻━┻
Adding a boolean field without a NOT NULL constraint is a ticking bomb. Make sure to update all the boolean fields in your database using the following migration:
 change_column_default :users, :boolean_attribute, false
 change_column_null :users, :boolean_attribute, false
Database foreign key constraints
Database level constraints are not a first-class citizen in Rails apps. You can create a database relation without adding a corresponding foreign key, and Active Record will work correctly. Building a database schema without enforcing it using built-in PostgreSQL mechanisms can lead to various issues down the road. It is usually a good idea to add a foreign key constraint when creating has_many/belongs_to relation.
I always prefer to explicitly add foreign key, column, and indexes, instead of using add_reference helper method. There's enough magic in Active Record already.
Adding posts relation to User model can be done using the following migration:
add_column :posts, user_id: :integer, null: false
add_index :posts, :user_id
add_foreign_key :posts, :users, column: :user_id
With this database structure, it will be impossible to leave orphaned post records in the database. Trying to remove a user, who still has some posts will result in an ActiveRecord::InvalidForeignKey error.
To "delete cascade" or "dependent destroy" ?
We can ensure removing the children records when the parent is destroyed using Active Record callback (with dependent: :destroy has_many method option) or directly in the database. Adding on_delete: :cascade to add_foreign_key method will remove children using database level triggers. It will be much better in terms of performance but would not execute ActiveRecord callbacks for removed posts.
Despite all the hate those callbacks get they are still useful in certain cases. One example could be a well-known Carrierwave gem. It uses callbacks to remove associated files when an object is destroyed. Removing objects using on_delete: :cascade approach would result in orphaned files stuck forever without any reference on S3 or wherever you keep them.
My approach would be to use foreign keys for ensuring integrity, but stick with dependent: :destroy for removing objects. Skipping callbacks could lead to surprising behavior if you are riding on Active Record for PostgreSQL interactions.
Summary
This post just scratches the surface of the complex topic of data integrity and validation in Ruby on Rails web apps. Active Record is a powerful tool that makes creating complex database schemas just too easy, without forcing developers to think about how it works under the hood. Moving at least some of the rules to database level is a good starting point to keeping your Rails apps healthy in the long run.

Of course, the nitrogen generator mentioned here is PSA type, that is, molecular sieve nitrogen generator.
1、 The main output of PSA type nitrogen generator is suitable for 1-3000 Nm3 / h. If the output is larger, the cryogenic air separation is recommended to be more economical, and the purity can be from 95% to 99.999%.
2、 PSA type nitrogen generator is mainly used in the industry, which is the reason why it is widely used in China. Including, food packaging, if some puffed food, dried fruit, etc., nitrogen can significantly extend the shelf life of food. Petrochemical industry, which is also a wide range of applications, a large number of chemical products in the production process with nitrogen purge or nitrogen protection, to ensure the safety of the overall process. Another electronic welding SMT industry, this industry for nitrogen protection is to protect the good conductivity, brightness, performance of the welding circuit board. The main nitrogen can improve oil production, and the use of nitrogen has been generally considered to be able to increase oil production in domestic and international oilfields.
3、 The domestic demand for nitrogen is among the top in the world. Now the domestic economic growth is more obvious than before 2000, so the domestic infrastructure and industrial capacity are booming, which also makes our industrial level and production capacity increase, and the demand for nitrogen and nitrogen equipment is greatly increased. This has also brought benefits to our industry.
4、 How to select the nitrogen production enterprises with good quality. A long time and a long period of time are of course a conventional standard of measurement, but also depends on the concept of business operators, whether they want to make quick money or are willing to do a business? At present, China's enterprises have a short life span, few high-quality enterprises and low brand recruitment. There are many external factors and many internal factors. We hope to be a long-term enterprise supporting national construction. From the early stage of its establishment, we strive to be an enterprise with high-quality products and timely after-sales service. At the same time, we are concerned about national construction and public welfare. We should not only realize economic value but also social value, and let employees participate in it. We have a sense of belonging and honor. I am willing to have this career to continue to struggle.


7 Ways to Deal With Arrogant People
7 Ways to Deal With Arrogant People
Image by 愚木混株 Cdd20 from Pixabay
Arrogant people do think that they are and will always be right. They get stuck to false assumptions and ignore hearing what other people say. They will use superior language, bully people, and become bigoted of people, or just act total rudely.
They consider themselves excellent. How you react to them becomes necessary when peace of mind is considered.
Your reply to an arrogant person is also a representation of your uprightness as a person who holds up himself.
Sometimes it becomes difficult to be sound these people because they can begin to pick away your self-confidence.
We run out of words and forget how to react to the situation.
How to save yourself from the verbal attacks of an arrogant person?
If you cross paths with these people who are self-stuck, do follow these suggestions.
So, How to deal with arrogant people? We have added different strategies to the tricky points.
Here are 7 Ways to deal with arrogant people
1. Have high self-confidence:
One of the best ways to face an arrogant person is by displaying your high confidence. Always enter into conflicts with arrogant people only when you are strong and have a depth of knowledge about a matter.
Only then you'll know where are they going wrong. It is important to point them out. It will help you get less victimized by them. You will notice how their behavior changes when that can't relate to you. Instead, they would start saying bad things that are unjustifiable. But have faith in yourself. Confusing them in their own words is your bigger trick.
2. Remember they are insecure:
Try finding sympathy in yourself if you can. Arrogant people bullies and harasses people to take control of them. It's just a reflection of their fear of being controlled. They would never admit their wrongs and stuck to pretenses. Thus they would never take account of your advice or suggestions, no matter how hard you make him try to believe. As being self-centered and the inability of open-minded, their life experiences are less. It becomes too hard to sympathize with someone of this quality.
Do not put them down. Just let them enjoy the fruits of their insecurities because they are never able to see their shortcomings.
3. Don't let it get to you:
Once you allow them to rule or control you, they won't leave a dot to not put you down. They have a very low mentality of finding happiness in other's troubles. Much like a narcissistic nature. This is much easier said than done. Just imagine, what if the person isn't trying to be rude towards you and just try hard to figure out the bigger view. There could be other reasons for a person's conduct. Try spotting them out and blur out these scornful criticisms.
Just laugh it out. Do not stress over it.
4. Be empathetic, but don't try to fix the person:
One's demand for superiority is profoundly grounded and ranges from lower appreciation to a deep craving for approval to a lack of compassion for those who seem less successful. Only the domineering person can deal with such a problem and with a continued push. On the other side, it brings peace to your heart and possibly to the circumstances if you have compassion for the grief of others.
5. Be mindful:
Whatever we decide to do, we should do them carefully and with much love as practicable. They make others lose their temper and become the worst version of themselves. You need to be very careful while handling these people. They are rotten from inside and would spread that rot within us too. We should be careful while dealing with them. Try to perform the sport of your life rather than trying to fit into someone else's. Be faithful to yourself always.
6. Try changing the topic of the conversation:
If nothing works wonders, try to change the topic of conversation. Arrogant people love to dominate over one particular topic, and if the decision to change the topic has been taken, they will bounce back. They will become defenseless. If you try switching to something that is neutral or something you know more about, they will try to find a way to jump back to the previous topic. They play dominating roles in our society. When people like us ask them anything out of the syllabus, they wouldn't answer them or might speak badly about you. After all, this is what they know.
You should try to be calm in such situations.
7. Avoid interaction at all possible means:
If you are in close proximity with such a person, your days can be tough. Do whatever it takes, to lessen the effect of this soul. Do not get close to them or park cars near their cars, I mean never!
When you meet them just smile and exchange glances. You might say "good morning", "good day" just in case, or occasional "hmm".
Do not let them know that you're avoiding them and don't want to interfere in any of their matters.
Find more ways to walk out and ignore these people. To maintain your own understanding, it's best to keep a proper distance between you.
Just dodge them by any means!

What's vibration detector (shock sensor) how it works?
The sensor for vibration detection is a vibration detector (or shock sensor), the detector must have a mechanical displacement to generate the alarm signal; vibration detection equipment is not only best suitable for file cabinets, vaults, strongrooms, safes and Automated Teller Machines (ATM), confidential protection special objects, but also suitable for other systems in combination, to prevent intruders break in from wall. How to use the vibration detector in correct application is very important. It is often used to provide protection in a special object where protected area that with staff's activities.
There are two major detection methods for vibration detector; the one is mechanical detection, it works as a ON/OFF switch using the mechanical movement of metal contact, the other is acoustic sound detection. Compare to acoustic sound detection, adopts mechanical detection vibration detector only detect the true physic vibration with low false alarm. The vibration detector that is based on acoustic sound detection (with microphone), it may trigger false alarm by high noise from car, thunder in summer.
1. There are different types of vibration detectors according to the application or protection objects.
a. Building Vibration Intrusion Detector
The detector can detect the mechanical vibration (shock) from the wall, and send alarm signal to alarm system.
b. Geosound vibration intrusion Detector
The detector can detect the vibration caused by pedestrains or vehicles on the ground.
c. Safe Vibration Intrusion Detector
The detector detects the vibation cased by the hit or abnormal open of the safes.
2. Typically most of vibration detectors with NC (Normal Close) output for alarm connection. The connection for vibration detector to alarm system is simple, you may need to connect the EOL resistor in series between detectors and zones (alarm system).
3. Tips on installation the vibration detector
- Vibration detectors is used for detection of intrusion for vaults, strongrooms and Automated Teller Machines (ATM's).
- When install the vibration detector on the wall of room, then the installation height should be 2-2.4 meter from ground, The device need to install in dry environment.
- When place the vibration detector underground, the depth should be 10cm.
- Installation should avoid the places where there is vibration souces ( motors, transformer, fan, air-conditioner).
- Do not install the device where with RF interference.

A simplified guide to your housing and eviction rights
What is the purpose of this leaflet?Many women are evicted from their homes by their husbands, partners, family members or the owners of their homes. Often, women are evicted with their children and do not have anywhere else to live. They then turn to shelters for temporary assistance or live in undesirable and unhealthy living conditions.
Sometimes these women have contributed to the home financially or in other ways such as by cleaning and maintaining the home or by taking care of the children. The husband or partner is then able to go to work and earn money to pay the bond over the property or the rent.
Some women reside on land in farm, agricultural or rural areas and are evicted from their homes with their children by the owners of the land
Women do not always know what their legal rights are to housing or their rights in terms of evictions and are evicted from their homes unfairly and illegally.
There are also circumstances where women who are in abusive marriages or relationships share a home with a husband, partner, exhusband, expartner or family member who abuses them. They are not aware that they can obtain a protection order that prohibits the abuser from entering the home or a part of the home.

Return to Classical Laissez-faire Science
Although RSI offers a variety of free educational programs, it is our Undergraduate Fellows Program that best exemplifies the quintessential RSI vision. The RSI Undergraduate Fellows Program evolved from the personal experiences of its founders – laissez-faire science. We challenge our fellows to do something extraordinary and then give the freedom and resources (to the extent possible) to proceed. Fellows are given the freedom and independence to develop their own vision and personal scientific style– with guidance close at hand when needed or asked for. We wholly embrace Physics Nobel Laureate Andre Giem's philosophy.
"Curiosity-driven research. Something random, simple, maybe a bit weird—even ridiculous. Without it, there are no discoveries." – Andre Geim, Nobel Prize in Physics 2010
Giem is the only Nobel Prize winner (for discovery of the wonder material graphene) who also won an Ig Noble Prize (for levitating living frogs with magnets). Giem is not afraid of ridicule or willing to temper his creativity. With great risks, great rewards are possible!
"Frankly, I value both my Ig Nobel prize and Nobel prize at the same level and for me Ig Nobel prize was the manifestation that I can take jokes, a little bit of self-deprecation always helps."
The RSI undergraduate fellows program is designed to specifically allow undergraduates the opportunity to pursue an independent, or group project. The program begins with the immersion/incubation period, when fellows learn wet lab techniques, judicious use of the scientific literature, and survey the breadth of the scientific landscape. Ideas incubate and begin to take shape. Armed with their newly acquired scientific knowledge, fellows embark on a question or problem that inspires themthe formulation period. The process is as much a pedagogical experience about scientific research, as it is about self-discovery. Because our fellow's scientific naiveté persists, the incubation period often extends out to near the end of the program, when everything coalesces. Although the minimum fellowship period is 6 months, those who have benefited the most from the program continued for well over 18 months. Traditionally, to become semi-independent in science requires years in graduate school and then post-doctoral work. In comparison, our fellows achieve this in an accelerated time frame.
The development of a refined scientific acumen, beyond a mere dalliance with the scientific method, requires constant sharpening and enough time, independence, and buffering from the culture of conformity to develop the scientific skill set to ask insightful questions, pose and then validate key hypotheses. Fundamental discoveries do not result from the contemporary, highly popular, and derivative "plug and play" research style, but rather from true exploration of uncharted waters. What you sow is what you reap. Although programs such as iGEM may pay lip service to accomplishing these lofty goals, sufficient time, resources and inherent system design remain limiting. Even our own program suffers from insufficient time for our fellows to reach maturity. Thus, we propose a true back to the future Bio 2.0 science pedagogical approach, where science is conducted as it was in the classical era, but using the power of modern technology and communication tools.
"The learning experience at RSI is incredible. I felt like I truly understood what it meant to do research, and design experiments, and what a great lab environment can be."
–Hugo DeckerWeill Medical College of Cornell University, Memorial Sloan-Kettering Cancer Center and Rockefeller University MD/PhD Program
"I have a passion for research because I get to sit on the edge of scientific discovery. The edge may be precarious at times, but by collaborating with colleagues, being creative, and not giving up, incredible things can ultimately be accomplished."
-Jack Tung – Medical College of Georgia MD/PhD Program

In the fishbowl version of a pickup joint, the mere sight of a well-endowed male swordtail causes genes to switch off in the female's brain. The result: She throws caution to the wind to win the hunky mate.
Female swordtails are attracted to large males adorned with body ornaments, such as long tails and striking coloration.
In a series of fish-tank experiments, researchers showed that when a swell swordtail catch is around, certain of the female genes linked with sexual behaviors were in a sense modified. The gene changes occurred in just 30 minutes, quick enough so the preferred male could bait the female with body ornaments and size before reeling her in.
The phenomenon, detailed in the Dec. 4 online version of the journal Proceedings of the Royal Society of London B, suggests a suite of genes that under normal circumstances keep female swordtails from mating can be switched off when preferred males are nearby.
"When females were most excited—when attractive males were around—we observed the greatest down regulation [turning off] of genes," said Molly Cummings of the University of Texas at Austin. "It's possible that this could lead to a release of inhibition, a transition to being receptive to mating."
Cummings and UT colleague Hans Hofmann placed individual female swordtails into the centers of tanks for 30 minutes, with each tank separated into three connected zones. The females were accompanied by one of the following: a pair with one attractive male and one unattractive male; unattractive males; other females; or no fish.
Meanwhile, the researchers extracted so-called messenger RNA (mRNA) from the females to determine which genes were being "turned on" and "turned off."
A gene is a set of biological instructions, so turning off a gene prevents instructions from being carried out. Switched on, the gene's DNA turns into mRNA, which ultimately gives rise to the mighty protein. And it's proteins that carry out the processes and activities of living things.
In the presence of both an attractive male and unattractive one, females would slowly swim away from the attractive males and then quickly turn around to face their mates. This gliding behavior typically precedes copulation in swordtails.
Genetic analyses showed that 77 genes out of the 3,000 analyzed were involved in females' mate-choice behaviors. Ten percent, or about 300 genes, could change their activity depending on mating conditions.
While some genes were turned on when females found a male attractive, a larger number of genes were turned off, they say. The same genes that turned off when females were with attractive males turned on when they were with other females or the puny males, and vice versa.
The off or "down-regulated" genes could play a role in inhibiting sexual behaviors, the authors speculate. So when the genes shut down or decrease their activity, they release the chastity belt, allowing females to pursue and mate with the dazzling dudes.
"In the presence of the attractive male, [these genes] are inactivated and as a consequence this inhibition goes away," Hofmann told LiveScience.
He added, "The genome is very dynamic and changes in genome expression occur all the time as we get exposed to new environmental situations, in this case social situations, continuously."

ClayMetrics is new, but it is based on several well-established disciplines. Collection and analysis of clay shooting process and results can yield huge benefits by focusing practice time where it will be most useful. Deriving improved measures and analysis of performance are two more links in the success chain. That's the physical side.
It is generally recognized that top athletes perform at their peak when "in the Zone". First difficulty is recognizing when you are in the zone and when you are not. Second step is learning techniques to get in the Zone on demand and return to it as needed.
ClayMetrics is the scientific study of clay target shooting both physical and mental.

My T'ai Chi teacher, Master Xu, has a way of describing athletes who become really good at basic skills, but never get beyond using physical force to be successful at their sport or activity. "Top of their class in grade school," he would say, with laughter in his eyes. Basic skills are key to efficiency, relaxation, and form. The key is to integrate these skills into every movement and to trust that each movement does its part.

In running terms, "grade school" can be thought of as the time spent improving your running technique. Once you're running more efficiently and comfortably, you can begin to build distance—the "middle school" phase. With good running technique under your belt and a solid conditioning base, you are fully prepared to graduate to "college," or a half marathon or full marathon distance.
More: Chi Running and the Art of the Long Run
Every year, the number of runners choosing "college" continues to climb. Endurance running is a challenging way to reach physical and mental goals, and it can be a life-changing and joyful experience. Unfortunately, just as an unprepared student struggles when he or she moves up to the next level too quickly, so does a runner who takes on too much with an unprepared body and mind. Injury, disappointment, and an unfinished race are just a few consequences of inadequate training.
If you're a beginner runner considering a half or full marathon, a seasoned distance runner, or a performance athlete looking to improve your race times, Chi Running offers an effective way to train for longer distances. Traditional training strategies are to run, run, and run some more. These philosophies are only about increasing mileage so you can finish your race. Simply completing the distance is a great goal, but the Chi Running philosophy believes you can do a lot more than just cross the finish line. You can set a new PR, spend little to no time recovering... and do it all with a smile.

This is why "grade school," or the preparation phases of your training, is even more important than running endless miles. As you train for your next distance event, follow these seven manageable phases laid out in Chi Marathon: The Breakthrough Natural Running Program for a Pain-free Half Marathon and Marathon, Chi Running's course curriculum for mindful, productive training:
Visioning and Planning
Take time to plan your goals for training and the race itself. Ask yourself why you want to take on the half or full marathon distance. Real purpose helps motivate us and makes training and racing more fulfilling.
Learn the Chi Running technique and practice specific Form Focuses on every run. You'll begin to sense Chi (energy) in your body and learn that tension (and pain) is where chi is not flowing, where injury might occur, and how to relax and make the right adjustments.

Why Are Words More Memorable Than Numbers?
Assuming that they are, I'm sure for some people it's actually the other way around.
Is it because numbers describe a relationship between entities rather than the entities themselves?
it's because like there's not much material difference between 1178 and 1179, they're too specific aren't they.

A simple points system may soon help guide treatment of elderly heart failure patients. Researchers at Washington University School of Medicine in St. Louis found that by counting how many of seven easy-to-obtain health factors a patient has, physicians can estimate the patient's risk of dying.
The points system may steer doctors toward considering more aggressive treatments such as implantable defibrillators and pacemakers for those at low risk of death. However, elderly patients with a high risk may want to avoid stressful and unnecessary medical intervention and may benefit most from palliative or hospice care.
"It has typically been very difficult to predict how long a person hospitalized with heart failure may survive," says senior author Michael W. Rich, M.D., associate professor of medicine and a geriatric cardiologist at Barnes-Jewish Hospital. "That has made it hard for the treating physician to know how aggressive to be with therapy."
Heart failure afflicts about 5 million people in the United States, hospitalizing more than a million patients each year. The incidence of heart failure increases with age, and with people 65 and older becoming the fastest growing segment of the population, the personal and financial burden of heart failure will likely increase.
In their study, which followed 282 elderly heart failure patients for up to 14 years, the researchers identified seven factors that most affect patient survival:
The study, published in the September 25th issue of the Archives of Internal Medicine, showed that patients with four or more of the risk factors had a low probability of surviving longer than six months. But if patients had none or just one of the factors, they had a good chance of living five years or more. Patients with two to three factors were likely to live at least a year. The patients in the study received a variety of treatments as determined by their physicians.
"The system is easy to use, and the variables don't require any specialized testing -- they are part of routine medical histories or basic lab tests," Rich says. "If the system can be validated by further studies, it can play a role in helping physicians tailor care to individual patients. If a person has a limited life expectancy, it may not be in his or her best interest to recommend invasive, uncomfortable or risky procedures. On the other hand, an elderly person with only one risk factor could potentially be considered a good candidate for an aggressive treatment such as a defibrillator."
Other factors that might have been expected to affect survival, such as the amount of blood the heart can eject during pumping or a patient's body mass index, didn't seem to influence survival times. Rich emphasizes that each of the factors identified has been linked in previous studies to poor prognosis in heart failure patients.
"We didn't find any new risk factors, which means there's good data to support that these factors truly are predictive," Rich says. "We've pinpointed the seven that are the most predictive and shown that the number of risk factors can give a reasonable estimate of the probability of living for six, 12 or 60 months."
The researchers next aim to better identify the heart failure patients not likely to survive six months so that they can be referred for hospice care.
"Hospice is very nurturing for both patients and family members," Rich says. "There is considerable evidence that patients derive significant benefit from it. If we can predict mortality within six months, we can more easily establish eligibility for hospice care."

Taken from
The book describes a train journey from Cairo to Kafr et Zayat station at Tantah. This illustration appears to depict a woman clad in black and wearing a shawl, citing in amidst the ruins of some ancient city, weeping, presumably for her lost husband. It is not clear whether she is in a graveyard or by a some ancient tomb. The engraving is signed by the engraver or artist, Leopold Carl Müller.
An endless breadth of green fields spreads on every side, interspersed withvillage that look from afar like tumuli, or ant-hills, shaded by palms, and not unfrequently clustering round the rubbish heaps and ruins of some destroyed city. Camels and asses, with their drivers, pass in long files along the dykes that stand up high above the plain; black buffaloes go down to the water to drink, and birds, large and small, far more numerous than in Europe, people the air. Here buffaloes are grazing, there half-naked men and women, in long blue garments, are labouring in a cotton-field." (p. 620)

Data Management Platforms (DMPs) are software systems that collect, store, and analyze data from various sources to help healthcare marketers make data-driven decisions. These platforms are designed to help healthcare marketers better understand their target audiences and make more informed decisions about how to reach them.
DMPs collect data from a variety of sources, including website analytics, social media, and offline data sources such as point-of-sale systems. The data is then organized and analyzed, providing healthcare marketers with a comprehensive view of their target audience.
One of the key benefits of DMPs is their ability to segment audiences based on specific characteristics, such as demographics or behavior. This allows healthcare marketers to create targeted campaigns that are more likely to resonate with specific groups of people.
DMPs can be used to segment audiences in a number of ways. For example, healthcare marketers can segment audiences based on demographics such as age, gender, and location. They can also segment audiences based on behaviors such as website browsing history or social media activity.
Once an audience has been segmented, healthcare marketers can use this information to create targeted campaigns that are more likely to resonate with that specific group of people. For example, if a healthcare marketer knows that a particular group of people is more likely to be interested in a certain type of healthcare product, they can create a targeted campaign that specifically targets that group.
DMPs can also be used to personalize the customer experience. By collecting and analyzing data about a customer's behavior and preferences, healthcare marketers can create customized experiences that are more likely to resonate with that individual.
For example, if a healthcare marketer knows that a particular customer is interested in a certain type of healthcare product, they can use that information to recommend similar products or send customized email campaigns. This can help increase customer engagement and ultimately drive sales.
Data Management Platforms (DMPs) are powerful tools that can help healthcare marketers make data-driven decisions. By collecting and analyzing data from a variety of sources, DMPs provide healthcare marketers with a comprehensive view of their target audience. This information can then be used to segment audiences, create targeted campaigns, and personalize the customer experience. With DMPs, healthcare marketers can make more informed decisions about how to reach their target audience, ultimately driving sales and increasing customer engagement.
A DMP (Data Management Platform) is a software tool used to collect and analyze large volumes of data from multiple sources. It helps businesses manage customer data, create targeted marketing campaigns, and improve customer experiences.
A DMP can store first-party, second-party, and third-party data. This includes data from websites, social media, email campaigns, mobile apps, and other online platforms. The data is then processed, analyzed, and stored in the DMP for further use.
Using a DMP for marketing can help businesses improve customer targeting and personalization, optimize marketing campaigns, increase customer engagement and loyalty, and enhance overall customer experience.
A DMP and a CRM system serve different purposes. A DMP is used to manage large volumes of data from multiple sources, while a CRM system is used to manage customer interactions and relationships. A DMP is used to create targeted marketing campaigns based on customer data, while a CRM system is used to manage customer interactions and customer service.
Some popular DMPs in the market include Adobe Audience Manager, Oracle BlueKai, Salesforce DMP, Lotame, and Krux.
Yes, a DMP can be integrated with other marketing tools such as ad servers, demand-side platforms (DSPs), and supply-side platforms (SSPs). This allows businesses to create more targeted and effective marketing campaigns.

The overall aim of the IC3 Programme is to improve Punjab Police's operational efficiency by deploying new hardware using up-to-date technology that will enable the Police to adopt more efficient working practices and new operating concepts. The role of the Police will not fundamentally change by the introduction of the IC3; the efficiencies relate to how that role is carried out from both process and performance perspectives. In progressing towards greater efficiencies, one of the IC3 aims is to bring together various elements of Punjab Police operation to work as a more unified team.
The IC3 operations will integrate the Command, Control, and Communication functions through 5 Services areas:
- Emergency Call Centre (ECC) – ECC will be handling all incoming and outgoing public trunk calls in wake of emergency.
- Dispatching Centre (DC) – DC will dispatch, monitor and support operational resources efficiently and timely manner.

- Video Wall Management System (and video wall) to display video streams on the video wall
- Automatic Number Plate Recognition (ANPR) Control System to control all ANPR equipment and archiving/retrieving recognized license plates
- CCTV Control – CCTV Control will operate as a receiving and recording point for CCTV images that are available to the CCTV matrix for IC3 Centre. Images can be displayed and, where appropriate, passed into the SOMS and CMC at that Centre for viewing at work-stations and/or for display on the video-wall.
- Crisis Management Centre (CMC) – CMC will plan and manage all the pre-planned and spontaneous major events through a defined escalation process to contain and manage a situation or an event through a clearly defined command structure. It will contain integrated tools that merge information in an environment that provides leadership quick and accurate data to evaluate situations.
These services will generate a level of required support that in some cases will be new work but in others will call upon existing support organizations and processes. In particular these existing organizations will include database management, human resources, finance and facilities management. When completed, the new build IC3 Centre will become integral part of the technology infrastructure, allowing seamless access between the IC3 Centre and the wider Punjab Police (PP) and other agencies.

Cable stayed and suspension bridge. How to Design a Bridge 2022-10-13
Cable stayed and suspension bridge
Cable stayed and suspension bridges are two types of bridge designs that are commonly used to span long distances and allow for the passage of vehicles, pedestrians, and other forms of transportation. Both types of bridges utilize cables to provide support and stability, but they differ in the way that these cables are arranged and used.
A cable stayed bridge is a type of bridge that utilizes a series of cables that are anchored to a single tower or a series of towers. These cables are then connected to the roadway of the bridge, providing support and stability. The towers of a cable stayed bridge are typically much taller than those of a suspension bridge and are often designed with a distinctive and aesthetic appearance. Cable stayed bridges are commonly used to span medium to long distances, typically between 500 and 2,000 feet.
A suspension bridge, on the other hand, utilizes a series of cables that are anchored at both ends of the bridge and suspended above the roadway. The roadway of a suspension bridge is supported by a series of vertical cables, known as hangers, which are connected to the main cables of the bridge. Suspension bridges are capable of spanning much longer distances than cable stayed bridges, typically between 2,000 and 7,000 feet.
Both cable stayed and suspension bridges are known for their elegant and graceful design, as well as their ability to span long distances. However, there are some key differences between the two types of bridges. Cable stayed bridges are generally more efficient and cost-effective to construct than suspension bridges, as they require fewer materials and fewer cables. Suspension bridges, on the other hand, are able to span much longer distances and are often preferred for their ability to withstand strong winds and earthquakes.
In conclusion, cable stayed and suspension bridges are two types of bridge designs that are used to span long distances and provide a passage for vehicles, pedestrians, and other forms of transportation. While both types of bridges utilize cables for support and stability, they differ in the way that these cables are arranged and used. Cable stayed bridges are more efficient and cost-effective to construct, while suspension bridges are able to span much longer distances and are more resistant to strong winds and earthquakes.
Each suspender cable is engineered and cut to precise lengths, and are looped over the cable bands. There are multiple design options from which to choose with a cable-stayed bridge.

John Wesley distinguished between essential doctrines on which agreement or consensus is critical and opinions about theology or church practices on which disagreement must be allowed. Though today few people join churches based on doctrinal commitments, once a person has joined a church it becomes important to know the historic teachings of that church's tradition.
In Methodist Doctrine: The Essentials, Ted Campbell outlines historical doctrinal consensus in American Episcopal Methodist Churches in a comparative and ecumenical dialogue with the doctrinal inheritance of other major families of Christian tradition. In this way, the book shows both what Methodist churches historically teach in common with ecumenical Christianity and what is distinctive about the Methodist tradition in its various contemporary forms. Documents examined include The Twenty-Five Articles of Religion, The General Rules, Wesley's Standard Sermons and Explanatory Notes upon the New Testament, The Methodist Social Creed, and the Apostles' Creed.
