Abstract
The present-day Mars has no magnetic field which suggests that the heat carried out of its liquid core is largely driven by conduction. To constrain the heat flux from Martian core, we measured the temperature (T) dependent electrical resistivity of solid and liquid Fe devoid of contamination in large volume press at various fixed pressure (P) up to 22.5 GPa, corresponding to the P at the top of the Martian core. We also measured its P-dependent resistivity up to 22.5 GPa at room T. At a P range between 18 and 20 GPa, we observed a drop in the electrical resistivity of ~35 μΩcm which is attributed to a loss in long range order magnetic structure. This loss gives rise to an overall decrease in the electron scattering processes induced by magnon. The transition from long- to short-range order magnetic structure occurs in association with the completion of crystallographic transformation from α-bcc (ferromagnetic) to ε-hcp (paramagnetic). The decrease in the electrical resistivity at the same P range corresponds to an increase in thermal conductivity of ~30 Wm−1 K−1. The resistivity and thermal conductivity of liquid Fe at the Martian core mantle boundary (CMB) on the cores side are estimated to be ~68 ± 3 μΩcm and ~82 ± 3 Wm−1 K−1, respectively. The heat conducted along its core adiabat is found to be ~45 mW−1 m−2. With a core radius of ~1700 km, we obtain a value of 0.3 TW for its total surface heat flux. In comparison with the resistivity of Fe at the Earth's core conditions reported by a recent study, our result indicates that pure liquid Fe is electrically more conductive in the Martian core than in the Earth's core. Our results will complement the HP3 subsurface heat flux measurements in the on-going NASA InSight Mission.

why are coming-of-age ceremonies so important?
Coming of Age ceremonies are an opportunity for both the child and parent(s) to create a memorable, educational, rite of passage. As the child is transforming into a young adult, this ritual involves releasing of some parts of their childhood; old roles, perspectives and behaviors that no longer serve their highest good, and in return they gain young adult responsibilities and privileges.

QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO for Linux. It can hold any number of arpeggiator, sequencer, or LFO modules running in parallel.
Arpeggiator modules produce sequences depending on the notes sent to their input port, which is typically connected to a keyboard or another sequencer.
Step sequencer modules allow you to create simple linear, monophonic and globally transposable sequences similar to the first analog sequencers.
MIDI LFO modules independently produce MIDI controller data of adjustable waveform, time resolution, amplitude and duration.
A Global Storage Tool can store different setups and switch between them at a given time. It allows you to dynamically combine patterns and LFO wave forms.
For each module, an input note filter is available, and the output port and channel can be set independently. QMidiArp can be synchronized to an incoming MIDI realtime clock or as a JACK transport client. Most of the relevant control elements are accessible via MIDI controller through a MIDI-learn infrastructure. QMidiArp also has a log tool displaying the history of incoming MIDI events in colors depending on their type. It has support for JACK MIDI and ALSA MIDI backends. QMidiArp runs on Linux and uses the Qt toolkit. The modules are also available as LV2 MIDI plugins.

PostgreSQL
PostgreSQL is a object-orientated database. The main feature of a object-orientated database is that tables can inherit from other tables, which means they automatically get all the data columns of the table they inherit from (similar to object inheritance in object-orientated programming languages).
Inheritance is defined when creating tables with the INHERITS clause with the CREATE TABLE statement:
CREATE TABLE people (
 name text,
 age int
);
CREATE TABLE student (
 student_id text,
) INHERITS (people);
If a table already exists, you can inheritance via the INHERIT variant of the ALTER TABLE statement.
Working With PostgreSQL In Python
One of the most popular PostgreSQL libraries for Python is psycopg2. To install it on Ubuntu you will also need the libpg-dev package on your system:
sudo apt install libpq-dev
pip install psycopg2

Clarkdale AZ (July 9, 2019) – The Northern Arizona Audubon Society is pleased to announce that it has partnered with the Greenwood Fund and Yavapai College to provide a non-credit course on the natural history of the Verde Valley. The Greenwood Fund was started in memory of Dena Greenwood, a well-known and beloved member of the local community.
A longtime resident of the Verde Valley who passed away in 2018, Dena Greenwood, was a naturalist, ornithologist, educator and guide who devoted much of her life to inspiring others to cherish the remarkably diverse habitats that we have in northern Arizona. Among her many achievement were working with the City of Sedona on the creation of the Sedona Wetlands Preserve which has become a premier bird sanctuary and birding destination. The continuation of Dena's lifelong dedication to sharing nature with others was the inspiration for this effort.
In recognition of these contributions, her family and friends created the Greenwood Fund to honor her memory and to continue her educational dreams.
Members of the Northern Arizona Audubon Society have created a course titled An Introduction to Natural History Field Studies and Yavapai College enthusiastically agreed to incorporate it into the curriculum at their Clarkdale Campus starting this September 5.
This four-session course will introduce students to the diverse habitats of the Greater Verde Valley region with special emphasis on understanding why these habitats exist where they do and the characteristic species found in each. Participants will visit the Bubbling Ponds and Sedona Wetlands sanctuaries and other natural areas, learn about the region's plants and animals, and get a hands-on introduction to the art of birding and other aspects of natural history field studies. The class will focus on identification of local species and stress the interdependence of species within each habitat discussed. Opportunities to participate in natural history studies through a variety of citizen science projects will also be discussed.
Those interested in signing up for the course can do so on the Yavapai College website. Please go to: _URL_
All participants completing the course will receive a $50 tuition subsidy from the Greenwood Fund. For further information, please contact Brent Bitz at _EMAIL_

Georgia Doctor Practices After Sexual Assault
WSB-TV reported recently on a North Georgia doctor who committed sexual assault against his patients. He touched one of his female patient's genitals unnecessarily during exams without wearing gloves, and made inappropriate comments about how they felt, according The Independent Mail. The patient caught the conversation on tape. After several of his other patients with similar complaints came forward, he was prosecuted for sexual assault. Even after the tape was admitted as evidence, the jury in his first trial could not come to a verdict. Faced with a retrial, the doctor plead guilty to a reduced charge of simple battery and served a light sentence. Georgia's medical board placed restrictions on his license that require him to have a chaperone present when treating female patients and to wear gloves. But he is still practicing medicine in Toccoa.
Sexual Assault as Medical Malpractice
Dr. MacDonald has been convicted of a crime and censured by his professional body. There might also have been a civil lawsuit. Would Dr. McDonald's actions have qualified as medical malpractice? Medical malpractice lawsuits usually argue that the doctor failed to diagnose or treat a patient competently, leading to medical problems. In other words, the standards of behavior in a medical malpractice case are determined by the standards of the medical profession. Of course, the medical profession would normally expect its members to respect the privacy and dignity of their patients wherever possible, but enforcing this standard doesn't require a medical malpractice lawsuit. Typical medical malpractice cases involve failing to identify a medical condition correctly, failing to prescribe the appropriate medicine or treatment, or waiting too long to prescribe the correct treatment.
Civil Lawsuits for Sexual Assault
Victims of sexual assault by medical professionals can file a lawsuit for the civil law equivalent of assault and battery. Similar to the criminal version, civil assault requires that the doctor intentionally touch another person without that person's consent. If a doctor fails to get his patients' consent to touch them, he could be liable in a civil suit for battery. Section 16-6-5.1 of the Georgia Code specifically provides that, in sexual assault prosecutions against doctors who abuse their patients, consent is not a defense. Victims of assault can seek punitive damages (damages meant to punish the wrongdoer ), as well as damages for physical injuries and emotional distress.

Anti-academy protest outside school
Teachers, who have gone on strike in protest against plans to turn their school into an academy, were joined by parents as they demonstrated outside the school today.
Up to 40 parents attended the protest at Downhills Primary in Haringey.
Sarah Williams, 40, who has two sons at the school, said:
"There is absolutely no evidence that a change in structure improves children's educational outcomes.
"When the process first started I thought it was about improving the school, but as we've got further along I've realised it's all about [Education Secretary] Micheal Gove's ideologies that the only way to improve is to introduce profit.
"If you look at the figures, this school was already improving, and there's absolutely no reason why the school can't continue to improve if left the way it is."

Foram Test Construction
As we mentioned on the previous web page What is a Foram? forams are single-celled organisms with a protective test (shell). What is the test made from and how does the foram make it? There are two basic kinds of tests, soft tests made from an organic material called tectin (a complex carbohydrate plus protein material) and hard tests made from minerals. Hard, mineralized tests are much more common.
The evolution of a hard outer shell likely provided forams with additional protection against predators, physical damage, chemical changes, and as a means to control buoyancy. Mineralized foram tests are sorted into four major classes based on the method the foram used to construct them.
 1. Agglutinated
 2. Microgranular
 3. Porcellaneous
 4. Hyaline
1. Agglutinated - This test style was the first to evolve (more than 500 million years ago) and consists of tiny cemented grains gathered from the sea floor. Particles are glued to a tectin base with an organic, calcite or iron-bearing cement. Remember the organic tests we first talked about? This is simply an organic test with particles glued on top. At times these particles appear to have been gathered at random and at other times the grains are similar in size, composition or shape.

2. Microgranular - Test walls are composed of tiny, closely-packed grains of calcium carbonate, but with no obvious cement. For many years this group was lumped into the agglutinated class because it was thought that these tests were built from scavenged grains. In fact, some species do have some agglutinated grains thereby adding to the confusion. However, scientists are now convinced this group of forams actually secrets the tiny grains.

3. Porcellaneous - This test is composed of microscopic calcite needles formed inside the foram and then moved to the outside of the cell. Tests are generally white in color, but may be pink or colorless with an appearance similar to porcelain, hence the name "porcellaneous". Test walls are generally built of three layers - a central layer sandwiched between two outer layers. Calcite needles in the middle layer are arranged in a poorly-organized mesh-like network, while needles in the outer layers are arranged parallel to one another, providing the outside of the test with a smooth surface.

4. Hyaline - To build this type of test, the foram secrets one or more layers of calcium carbonate over soft tectin material that serves as a template for the final shape. Rhizopodia, thin organic filaments connected to the foram, assist with hyaline test construction by delivering liquid calcium carbonate to different patches of the exposed tectin surface. The patches of calcium carbonate eventually merge and harden into a solid shell. Hyaline tests are often translucent to light, and commonly have a glassy or milky iridescent appearance.

Novel and flexible ultrasound simulation with smartphones and tablets in fetal echocardiography
Arch Gynecol Obstet. 2021 Jun 4;1-11. doi: 10.1007/s00404-021-06102-x. Online ahead of print.
Abstract
Purpose: Evaluation of a novel ultrasound-simulation-app for training fetal echocardiography as a possible useful addition for students, residents and specialist doctors. Furthermore, comparison to a conventional learning-method with special attention on orientation and recognition of physiological structures.
Methods: Prospective two-arm study with the participation of 226 clinical students. 108 students were given an extract from a textbook on fetal echocardiography (PDF-group, n = 108) for 30 min to study. 118 students were able to use the new ultrasound-simulator-app (Simulator-group, n = 118) to learn for 30 min. The knowledge of the students was examined both before and after the learning-period by having them identify sonographic structures in videos using single-choice selection.
Results: There were no significant differences between the two groups regarding age (p = 0.87), gender (p = 0.28), and the number of previously performed ultrasound-examinations (p = 0.45). In the Simulator-group, there was a significantly higher learning effect regarding the proportion of students with an increase of correct answers in the video test examination (p = 0.005). At the end of learning, the students in the Simulator-group needed significantly less time to display the structures in the app's simulation (median initially 10.9 s vs. 6.8 s at the end; p < 0.001).
Conclusions: The novel ultrasound-simulation-app seems to be a useful addition and improvement to ultrasound training. Previous difficulties such as simultaneously having patients, ultrasound-machines, and professors at disposal can thus be avoided. This means that another important step towards remote learning can be taken, which has been proven increasingly essential lately, due to the COVID-19 pandemic.

Bichon Frise Diet & Meal Plan Advice
By Hungry Bark | June 21, 2021
Playful and peppy are two of the distinctive traits of a Bichon Frise. Overly friendly, Bichon Frise is known for being energetic to meet new friends and doesn't have much aggression in them.
The combination of friendly demeanor, size, and confidence make the Bichon an ideal dog for small spaces and city environments. They are highly trainable, and their engaging personalities make them one of the more popular of the smaller breeds.
Daily cleaning rituals and monthly grooming are essential to a Bichon's overall health and proper diet and exercise.
To ensure that you're providing the best opportunity for a quality of life for your Bichon, provide only the best food you can at mealtime. Know that not every meal plan is the same, so keep reading if you're curious about what to provide your Bichon for its excellent health.
The Importance Of Getting Enough Exercise
Another benefit to daily exercise is that it allows for your Bichon to socialize and explore its environment. Dogs instinctually will sniff and explore their environment to discover sources of food and potential threats.
Dogs rely heavily on the sense of smell, and a daily walk or another outdoor activity allows them to engage with other animals, stimulate their mind, and aid in digestion as well.
Depending upon where you live, we have a few suggestions about the types of activities you can plan for your Bichon.
The key to any activity is that you are playing and bonding with your Bichon Frise.
Daily activities are something that both you and your dog can look forward to and create opportunities to teach and reinforce proper social behaviors.
Walks: Daily walks are a must to engage your Bichon's curiosity and get some exercise in the process. Walks also serve as a great way to reinforce the bonds and work together on good behaviors.
Hikes: Depending on where you live, take your Bichon on a short hike if you have the opportunity. Keep in mind the terrain and weather as they may negatively impact your Bichon, but you expose your dog to new smells and surroundings by getting out of your immediate neighborhood.
Dog Park: Dog parks are great for socialization skills and get some quality exercise. As Bichon are hyper-loyal, a dog park only scratches one part of their exercise needs.
What plays a significant role for Bichon's is bonding with their owner, so if you go to a dog park, expect to be engaged in their fun.
Swimming: Swimming is a great low-impact activity for older Bichons that may experience joint issues. It is a full-body workout that has significant cardiovascular benefits as well.
The Type Of Nutrition Your Bichon Needs
Even though they are friendly and peppy, your Bichon does have its personality, likes, and dislikes.
When deciding on the type of meal plan that is ideal for your dog, you must consider its age, weight, activity levels.
One more thing to consider is if there are foodborne issues that may cause allergies and intolerances.
Keep in mind that not all dog foods are manufactured with the same attention to optimal nutrition, and some subpar foods may impact your Bichon's optimal health.
Also, at different stages of your Bichon's life, they will have different nutritional needs.
Before we discuss the type of nutrition ideal for your Bichon, let's discuss some other crucial factors in making your meal plan decision.
Save time shopping,
get it delivered.
Your Bichon's Age And Weight
Striking the right balance of nutritional and caloric needs can be a little overwhelming at first. We suggest you factor in your dog's age first and foremost, then consider its weight and overall activity level.
Meal plans that focus on the suitable types of calories and nutrition and serving size will maintain the ideal weight for your Bichon.
How Active Is Your Dog
As you evaluate different foods, your next consideration is your Bichon's overall level of fitness and activity levels.
Some dogs are prone to overeating or being heavier than others, and knowing your dog's ideal weight, as well as its activity levels, are primary factors in choosing your meal plan.
Active dogs need much more protein than sedentary ones. A good meal plan should prioritize a single protein source such as turkey in the labeling as the primary ingredient before any carbohydrates or fats.
Does Your Bichon Have Allergies Or Food Intolerance
Food allergies and intolerances can appear randomly. That's why it's important to know what type of food your dog is eating.
Dogs who develop a food-borne allergy become more susceptible to additional allergies over time. This process happens because the immune system becomes over-stimulated and aggressively attacks other potential allergens located within the body.
Symptoms of food-borne allergies usually include digestive issues and/or excessive itching. Excessive itching can spiral quickly as it increases skin irritation caused by bacteria getting under the skin triggering the body's itch response.
Food intolerance occurs when your dog can digest a type of food. It may be due to an allergy or a toxic food source and can't be digested.
The best way to avoid potential food-borne allergies is to choose clearly labeled, high-quality dog food.
Why Your Bichon's Food Ingredients Are Important
The type of food you feed your Bichon is crucial to its overall health.
Avoiding foods that have a lot of fillers, additives, and preservatives is ideal. It is also essential to look for ingredient lists that show high protein levels, carbohydrates, and fats in that order.
Proteins are the primary energy source for your dog. They build muscle and help the heart perform its function effectively. Proteins also offer quick bursts of energy.
Carbohydrates break down into sugars in the body and provide a delayed energy source for your Bichon. One of the functions of sugar in the blood is that it serves as the primary energy source for mental function.
Fats provide long-term energy stored in reserves. Too much fat in the diet can lead to many health concerns, but every diet needs some fat levels for delayed energy, and fats aid in minerals and vitamins being absorbed by the body.
How To Read The Ingredients Label
When you read the food label of dog food, there are a few things you need to understand.
Dog food is listed by weight, making the first ingredient the heaviest and most prominent in the list. That means that a protein source should be the first ingredient listed followed by a specific type of carbohydrate such as "brown rice," to be followed with a source of fat before anything else such as vitamins and minerals are listed.
Reading a food label can also be misleading.
The FDA requires manufacturers to list the types of protein in a way that details the percentage included.
They have four different classifications, and understanding what each term means will inform you of the quality of food you're providing.
These terms you want to look for are "the 95% rule, "the 25% rule," "the 'with' rule," and finally, "the flavor rule."
The 95% Rule
Any ingredient listed, such as "chicken," must include 95% of that protein source in the ingredients.
The 25% Rule
Food descriptions such as "turkey dinner or salmon entree" mean that food manufacturers only need to include 25-94% of the total protein in the ingredients list by FDA standards.
The "With" Rule
"With" is another misleading term if you don't know. For example, "dog food with chicken" sounds healthy, but it means the product must have only 3% of chicken in the ingredient list by FDA standards.
The "Flavor" Rule
"Flavor" is another tricky way that subpar manufacturers make their foods seem more nutritious than they may be.
The "flavor" rule basically states that this term is used to describe the food. It needs just enough of the protein source to be traceable. In other words, the protein doesn't even need to have to be included; it just must have enough that could reasonably find it.
Looking for the correct type of meal plan can be tricky, so we've created the Hungry Bark Custom Meal Planner as a great place to start!
In as little as 2 minutes, the meal planner will customize your Bichons meal plan taking into account characteristics such as breed, age, weight, and activity level to provide a custom meal plan for a quality, healthy life.

Saving The Balili River: Does It Have A Chance?
Arthur Tibaldo, in his column for Baguio Sun Star recently penned a piece about saving and reviving the Balili River. It's a commendable cause and one that deserves the support of the citizens of Baguio City and La Trinidad. The river is basically dead and it has been for a very long time.
The river currently serves just two purposes. These are:
1) a source of water for vegetable and flower farms near its banks -Since the river runs below most of the farms it waters, farmers often use pumps to propel the water to higher elevations. If you live near the banks of the river, it is not uncommon to hear the gurgling sound of water pumps.
2) a dumping place for human refuse and wastes - It's a negative purpose, obviously. And it's the main culprit for the deterioration of the river.
Old news
Efforts to get the river to its original state (or at least near it) is a very old story that dates back to the 1980s. People have been trying to revive the river for the longest time. And nothing worked. This brings us to the question "Will the current efforts to save the river be successful where its predecessors miserably failed?"
Not trying to be too pessimistic but the more you look into how the Balili River got polluted, the more there's reason to believe that reviving it is a lost cause. It's close to impossible. The biggest reason is the fact that the river is surrounded by human settlements. The wastes from hundreds of sewers and canals all lead to the Balili River.
Just go to either Kilometer 3 or 4 or 5 and look at the banks of the river. You'll see huge pipes and canal outlets spewing wastes that originated from the homes of the people living there. And you can't blame them for they have no choice on where to direct their sewers.
In conclusion, all efforts to save and revive the Balili River should be supported but it's also worth noting the fact that the river can never be restored to its original state. The quality of the water that flows through it can be improved and the amount of wastes dumped into it can be lessened. And this will require regular clean-up drives. This is the only solution that's available for now. If we are talking about turning the river into one that can support fish, it's impossible. Let us also take into account the fact that populations near the river are growing. That means more sewers. And you know where these sewers will eventually lead to.

Many who can no longer work due to a physical or mental impairment may be eligible for disability benefits through the Social Security Administration (SSA) or an ERISA-governed employment benefit plan.
As you might imagine, those who review SSD and ERISA disability claims need proof that a claimant cannot work before approving them. It can be challenging to obtain approval, especially if you have a neurological condition. Sometimes, undergoing a neuropsychological evaluation can provide such proof.
Can an evaluation prove a neurological disorder?
Many neurological problems pose few physical signs, making it even harder to prove such conditions. A neuropsychological evaluation does not necessarily prove you have such a disorder. However, it may uncover invisible indicators of conditions like these:
- Traumatic brain injury
- Stroke-related impairments
- Brain tumors
- Dementia disorders like Alzheimer's
- Spinal cord and brain infections
These evaluations can also help medical professionals identify seizure disorders and their causes.
What does an evaluation entail?
A trained technician or psychometrist will first talk with you and ask questions about your cognitive abilities. With your permission, the technician may also speak with family members on the same topics.
After the discussion, you will complete several tests to measure your brain health. For example, you may have to solve puzzles and perform memory exercises.
The psychometrist then analyzes the evaluation results and makes an initial determination about your condition. After the exam, you will likely need an official medical diagnosis to support your disability claim.
You should know that even when these tests indicate a possible neurological disorder, it does not necessarily mean your disability claim will be approved. There are many reasons your claim may be denied, from missed deadlines to administrative errors. However, legal guidance and knowledge of the claims filing process may significantly improve your chances of success.

A Europe Made of Money
The Emergence of the European Monetary System
A Europe Made of Money is a new history of the making of the European Monetary System (EMS), based on extensive archive research. Emmanuel Mourlon-Druol highlights two long-term processes in the monetary and economic negotiations in the decade leading up to the founding of the EMS in 1979. The first is a transnational learning process involving a powerful, networked European monetary elite that shaped a habit of cooperation among technocrats. The second stresses the importance of the European Council, which held regular meetings between heads of government beginning in 1974, giving EEC legitimacy to monetary initiatives that had previously involved semisecret and bilateral negotiations. The interaction of these two features changed the EMS from a fairly trivial piece of administrative business to a tremendously important political agreement.
The inception of the EMS was greeted as one of the landmark achievements of regional cooperation, a major leap forward in the creation of a unified Europe. Yet Mourlon-Druol's account stresses that the EMS is much more than a success story of financial cooperation. The technical suggestions made by its architects reveal how state elites conceptualized the larger project of integration. And their monetary policy became a marker for the conception of European identity. The unveiling of the EMS, Mourlon-Druol concludes, represented the convergence of material interests and symbolic, identity-based concerns.

Our encoding for encrypted filenames is now open source
Why do Boxcryptor's encrypted filenames consist of Chinese characters? This is a question we often hear about our folder and filename encryption and today we want to give you a detailed explanation.
Filename Character Limit
The underlying problem in choosing the appropriate font is the character limit. Core elements of Microsoft Windows can only handle file paths with a length of maximum 256 characters. This limitation is relevant, for example, when using Windows Explorer. Since files with longer paths would therefore not be accessible, many cloud providers—Dropbox, for example—don't synchronize files with a path length of more than 260 characters.
However, encrypted filenames require even more bytes than plaintext filenames. Thus, we had to find a way to reduce the character count of encrypted filenames, so Boxcryptor would not constantly trigger sync issues.
The solution to this problem is to use Unicode characters instead of ASCII characters. While an ASCII character can only transport 1 byte of information, a Unicode character transports 4 bytes. Thus, for every 4 ASCII characters there is 1 single Unicode character.
Comparable to already existing methods for encoding like Base64, we have developed the binary-to-text method Base4K, which uses 4000 different Unicode characters. While Base64 requires more characters than bytes, Base4K requires fewer characters than bytes. Base4K is more than 50 percent more effective than Base64 in terms of character length.
So why do we use Asian characters for Boxcryptor? The answer is quite simple: We need 4000 different characters and there are just not enough ASCII characters in the Latin alphabet. Also, the required elements additionally had to meet several technical specifications:
- Consecutive points in the Unicode system
- Universal representability (this is not the case, for example, with some symbols such as control characters)
- Unambiguous distinguishability
The large size of the Asian character set proved to be perfectly suitable here. Base4k therefore maps bytes (0x00-0xff) to Unicode points in the ranges 0x4000-0x40ff and 0x6000-0x6fff. Thus, the selection was based solely on technical requirements.
The Asian character set contains many times more symbols than the Latin alphabet. Therefore, it is perfectly suited for our encoding of folder and file names. However, real Asian (e.g., Chinese) file names would look completely different, since the encoded symbols follow neither syntax nor language logic.
By the way: If you use Boxcryptor to encrypt files and folders with real Asian names, you should have no problem in most cases. "Normal" Chinese file names, for example, do not correspond to the structure of encrypted Boxcryptor file names, for example. Accordingly, they are not recognized as such. In the unlikely event that Boxcryptor misinterprets a file as encrypted, you can simply enable the "show also non-decryptable files" setting. This will also display misinterpreted, "real" file names normally.
Now Also Open Source
By the way, although we will not publish the source code of Boxcryptor in its entirety, we have also added a sample implementation of the Boxcryptor encryption algorithm on Github.


Geosmin-Petrichor
What is Petrichor? That's Geosmin You Smell
Geosmin is a chemical you've never heard of but your nose recognizes it whenever it rains. It is the chemical that produces that unmistakable aroma of freshly turned soil or rain mixing with dry earth. The smell is so distinctive it even has a name, petrichor, which loosely translates as earth odor. This chemical impacts our lives in many interesting ways.
Where Does Geosmin Come From?
Geosmin is produced from the breakdown of organic matter by a variety of microbes such as cyanobacteria, actinomycetes & streptomycetes that are found in soil. It finds its way into various fruits, vegetables & even fish. In some cases it enhances the flavor of the food, in others it can be a nuisance. (1)
Does Geosmin Affect Our Food?
Geosmin is largely responsible for the earthy taste of beets which are used in borscht (beet soup) and produces sucrose, the same sugar as sugarcane & a red pigment used a natural dye in ice cream, drinks & various dairy products. Geosmin can also be found in spinach, lettuce & mushrooms. (2)
What About Geosmin and Water?
Geosmin finds its way into multiple water sources such as irrigation ponds, drinking water reservoirs & runoff catch basins. Its distinctive odor is undesirable so municipal authorities treat your water before it finds its way into your home & out your taps. The chemical is not toxic at naturally occurring levels. In fact some wines are enhanced by it while others are not. (3)
Geosmin and Evolution
Our noses are exceptionally sensitive to geosmin such that we can detect it in low parts per trillion (ppt) concentrations. For dogs this ability applies to a vast range of chemicals but for humans, this is very unusual. It has been suggested that sensitivity for this smell has been strongly selected for throughout our evolutionary history. It enabled us to find water even in arid environments. Of course, in this regard we are not unique. Camels are thought to be able to find oases many kilometres distant even before we can. (1).
Geosmin The Molecular Mobile
If you've ever taken organic chemistry, there is a certain familiarity to geosmin. It is basically 2 cyclohexane rings with 2 methyl & 1 hydroxyl group attached. As a mobile, it looks a bit like a space station you might see in old science fiction TV episodes & movies. You can build your own by entering geosmin in our 3D Molecular Model Builder.

When designing integrated microfluidic systems of the type shown in Figure 18.1, some important objectives are to:
1. Increase the throughput.
2. Improve the homogeneity of the mixture.
3. Obtain higher separation efficiency.
4. Perform detection faster.
However, it may not be possible to attain all these objectives, and there
can be a trade-off leading to an optimized design. In this section, using the techniques discussed in Chapter 17, "easy-to-use" circuit and device models are presented, which can be used to explore the design space and select an optimal design for integrated microfluidic systems to perform various functions. The model development is illustrated using the example shown in Figure 18.1. The models are, however, general enough that they can be applied or extended to other microfluidic systems. The development of a compact/circuit model for fluid flow due to a combined pressure and electrical potential gradient is first discussed. The compact model is described in two parts, namely, the electrical model and the fluidic model.
18.1.1 Electrical Model
For microfluidic devices that rely on the electrokinetic force as the driving force, the electric field must be computed first. In the case of electroosmotic flow (see Chapter 7 for details; here we restate only the essential equations to derive the circuit models), the potential field due to an applied potential can be computed by solving the Laplace equation:
У2ф = 0, (18.1)
where ф is the electrical potential. Since equation (18.1) predicts a linear potential drop for simple straight channels, the potential variation can be represented by linear electrical resistances. In order to develop a complete circuit that takes into account the charge stored in the electrical double

I recently wrote the following sentence:
Please roll it back.
But if I were to describe the action on its own I would say:
This rollback was due to objections by the original author.
If I want to use "rollback" as a verb I have to split it up with an "it". My best guess is that "rollback" seems to be a compound noun birthed from a verb+adverb but we never got a verb compound form. Thus, the following is still incorrect:
Please rollback it.
Is there a term to describe the specific pair of "roll" and "back"? Describing this specific action will always need both words and the action itself now has an appropriate noun. But where did the combined verb form go?

This is the way that English works. Nouns combine; verbs stay separate. Your car can have a breakdown, but you don't say "my car breakdowned", you say "my car broke down". Similarly, you can't say "I breakupped" with my girlfriend, or "I am loginning" to my computer, even though you and your girlfriend have a breakup, and you have a login for your computer. – Peter Shor Feb 28 '14 at 23:26

Roll back is a standard phrasal verb. Roll is the verb part, and back is the particle.
Rollback (stress on first syllable) is an event nominalization from roll back (stress on second).
As a phrasal verb, roll back participates in the usual alternation with direct objects:
 - Roll the carpet/budget back. (Vb + Noun DO + Particle -- OK)
 - Roll back the carpet/budget. (Vb + Particle + Noun DO -- OK)
 - Roll it back. (Vb + Pronoun DO + Particle -- OK)
 - *Roll back it. (Vb + Particle + Pronoun DO -- NOT OK)
So there are two reasons why *rollback it is incorrect:
 1. rollback is a noun derived from roll back, and not a verb itself, so it can't take a direct object.
 2. roll back is a phrasal verb and must place pronoun direct objects between verb and particle.

It could work if you were turning something into a rollback, but that doesn't compute. If you are calling rake db:rollback, you're rolling the most recent migration back. rollback is a command to something. Like "hey, your changes broke the db, everyone roll back!!" In this case, it is yet another tech term, in this case, telling someone to roll back means run rake db:rollback. If someone had mis typed rake db:redo, but instead you wanted them to rollback, you could point to redo and say "rollback it", referring to turn redo into rollback. – Funkodebat Mar 1 '14 at 2:09
_USER_ I didn't understand a word you said. Are you a computer programmer? – Mari-Lou A Mar 1 '14 at 6:12
He means that it has a very specific (and extreme) meaning and context in information management. rollback is the name of a command (and therefore, a program that the command calls). This is on a command-line interface where all the commands are imperative verbs, and there is a convention that pronounced names can be used as verbs in speech. In this case, they are reified and don't follow the syntax of phrasal verbs, so that "rollback it" has a context and a meaning, and is not ungrammatical. This is how language changes; new environments, new adaptations. – John Lawler Mar 1 '14 at 16:12
I'm a RoR programmer myself. rollback is indeed the name of a command. But it does not immediately qualify it as a new verb with its own new rules separate from the verb "to roll back". Even if a term is added to the dictionary, it doesn't change grammar rules just because its meaning is specialised. There are furry mice in my house, computer mice on my desk, chocolate mice in my bag, and the Mice Galaxies in space. Likewise, it is bad grammar to say "We rollbacked the database last night." Instead, say "We rolled back the database." or "We rolled the database back." – Seth Jeffery Jun 29 at 9:33
According to the Google dictionary (though not as yet AHD or Collins), the word rollback is also a compound verb (sense (1) here ):
verb: rollback; 3rd person present: rollbacks; past tense: rollbacked; past participle: rollbacked; gerund or present participle: rollbacking; verb: roll-back; 3rd person present: roll-backs; past tense: roll-backed; past participle: roll-backed; gerund or present participle: roll-backing
 1. restore (a database) to a previously defined state.
It is such a recent development from roll + back that 'rollback it' sounds unnatural. 'Rollback X' (X a noun group other than a pronoun) sounds like 'roll back X' which isn't so outlandish. Almost certainly, 'rollback it' will become more common, especially with padding: 'rollback it to the last-but-one state'.
Compound verbs from the fusion of verb + adverb are usually head-second:
downsize; upgrade; outsource; input; overpay
– so the addition of an object, including it, doesn't sound too bad.
It appears that 'voiceover / voice-over' has been analogously verbed.

Ah, interesting. So the answer to my question is most likely, "It is too soon. Wait a little longer." Your other examples of compound verbs are really useful. +1. – MrHen Feb 28 '14 at 23:54
_USER_ Derivations like these are very slow to catch on because so many people object to them. A few like loginned / loginning have been making progress, but they're widely disparaged. They may never be accepted. – snailboat Mar 1 '14 at 3:51
'Stopover' has made it into Collins (though not AHD) as a verb. But this is intransitive and doesn't give rise to a weird-sounding pairing with 'it'. With 'rollback it', there is the strong influence of the correct-sounding (and of course correct) (apologies to the 'of course' 'patronising'-labeller – who has been known to add it himself; I think this would sound more pedantic without it) 'roll it back' (whether transitive multi-word verb or verb + DO + adverb). Here, 'roll back it' is ungrammatical, so 'rollback it' also sounds unnatural. – Edwin Ashworth Mar 1 '14 at 9:29
"Rollback" is the name of the operation done when you "Roll [a file] Back" to an earlier version. (Usually this is as a part of a change management system).
It isn't a verb. It is a noun made from a verb already. There's no sense in verbifying the noun obtained from nounifying a verb. What would happen when you described that? You could repeat forever.
You either "perform a Rollback Operation or you Roll the file back and call the action Rollback.

Revert might be a suitable alternative to rollback in your example.
Please revert it.

Using the AWS SCT user interface - AWS Schema Conversion Tool
Using the AWS SCT user interface
The following sections help you work with the AWS SCT user interface. For information on installing AWS SCT, see Installing, verifying, and updating the AWS SCT.
The AWS SCT project window
The illustration following is what you see in the AWS SCT when you create a schema migration project, and then convert a schema.
 1. In the left panel, the schema from your source database is presented in a tree view. Your database schema is "lazy loaded." In other words, when you select an item from the tree view, AWS SCT gets and displays the current schema from your source database.
 2. In the top middle panel, action items appear for schema elements from the source database engine that couldn't be converted automatically to the target database engine.
 3. In the right panel, the schema from your target DB instance is presented in a tree view. Your database schema is "lazy loaded." That is, at the point when you select an item from the tree view, AWS SCT gets and displays the current schema from your target database.
 The AWS SCT Project Window
 1. In the lower left panel, when you choose a schema element, properties describing the source schema element and the SQL command to create that element in the source database are displayed.
 2. In the lower right panel, when you choose a schema element, properties describing the target schema element and the SQL command to create that element in the target database are displayed. You can edit this SQL command and save the updated command with your project.
Storing AWS Service Profiles in the AWS SCT
You can store your AWS credentials in the AWS Schema Conversion Tool. AWS SCT uses your credentials when you use features that integrate with AWS services. For example, AWS SCT integrates with Amazon S3, AWS Lambda, Amazon Relational Database Service, and AWS Database Migration Service.
AWS SCT asks you for your AWS credentials when you access a feature that requires them. You can store your credentials in the global application settings. When AWS SCT asks for your credentials, you can select the stored credentials.
You can store different sets of AWS credentials in the global application settings. For example, you can store one set of credentials that you use in test scenarios, and a different set of credentials that you use in production scenarios. You can also store different credentials for different AWS Regions.
Storing AWS credentials
Use the following procedure to store AWS credentials globally.
To store AWS credentials
 1. Start the AWS Schema Conversion Tool.
 2. Open the Settings Menu, and then choose Global Settings. The Global Settings dialog box appears.
 Choose AWS Service Profiles, as shown following.

 The Global Settings dialog box with the AWS Service Profiles tab selected
 3. Choose Add new AWS Service Profile.
 4. Enter your AWS information as follows.
 AWS SCT option
 Action
 Schema/Database Name
 Choose the schema and database name that you want to filter on. For schema name, you can enter "%" to select all schemas.
 1. For Profile name, type a name for your profile.
 2. For AWS Access Key, type your AWS access key.
 3. For AWS Secret Key, type your AWS secret key.
 4. For Region, choose the region for your profile.
 5. For S3 Bucket, choose the Amazon S3 bucket for your profile. You need to specify a bucket only if you are using a feature that connects to S3.
 6. Choose Use FIPS endpoint for S3 if you need to comply with the security requirements for the Federal Information Processing Standard (FIPS). FIPS endpoints are available in the following AWS Regions:
 - US East (N. Virginia) Region
 - US East (Ohio) Region
 - US West (N. California) Region
 - US West (Oregon) Region
 5. Choose Test Connection to verify that your credentials are correct and active.
 The Test Connection dialog box appears. You can see the status for each of the services connected to your profile. Pass indicates that the profile can successfully access the service.

 The Global Settings dialog box with the AWS Service Profiles tab selected
 6. After you have configured your profile, choose Save to save your profile or Cancel to cancel your changes.
 7. Choose OK to close the Global Settings dialog box.
Setting the default profile for a project
You can set the default profile for an AWS SCT project. Doing this associates the AWS credentials stored in the profile with the project. With your project open, use the following procedure to set the default profile.
To set the default profile for a project
 1. Start the AWS Schema Conversion Tool.
 2. Open the Settings Menu, and then choose Project Settings. The Current project settings dialog box appears.
 3. Choose the Project Environment tab.
 4. For AWS Service Profile, choose the profile that you want to associate with the project.
 5. Choose OK to close the Current project settings dialog box. You can also choose Cancel to cancel your changes.
Storing database passwords
You can store a database password or SSL certificate in the AWS SCT cache. To store a password, choose Store Password when you create a connection.
The password is encrypted using the randomly generated token in the seed.dat file. The password is then stored with the user name in the cache file. If you lose the seed.dat file or it becomes corrupted, the database password might be unencrypted incorrectly. In this case, the connection fails.
Using the Union All view for projects with partitioned tables
If a source table is partitioned, AWS SCT creates n target tables, where n is the number of partitions on the source table. AWS SCT creates a UNION ALL view on top of the target tables to represent the source table. If you use an AWS SCT data extractor to migrate your data, the source table partitions will be extracted and loaded in parallel by separate subtasks.
To use Union All view for a project
 1. Start AWS SCT. Choose a data warehouse (OLAP) project.
 2. Choose Settings, and then choose Project settings. The Current project settings dialog box appears.
 3. Choose Use Union all view.
 4. Choose OK to save the settings and close the Current project settings dialog box.
Using AWS SCT tree filters
To migrate data from a source to a target, AWS SCT loads all metadata from source and target databases into a tree structure. This structure appears in AWS SCT as the tree view in the main project window.
Some databases can have a large number of objects in the tree structure. You can use tree filters in AWS SCT to search for objects in the source and target tree structures. When you use a tree filter, you don't change the objects that are converted when you convert your database. The filter only changes what you see in the tree.
Tree filters work with objects that AWS SCT has preloaded. In other words, AWS SCT doesn't load objects from the database during searches. This approach means that the tree structure generally contains fewer objects than are present in the database.
For tree filters, keep the following in mind:
 - The filter default is ANY, which means that the filter uses a name search to find objects.
 - When you select one or more object types, you see only those types of objects in the tree.
 - You can use the filter mask to show different types of symbols, including Unicode, spaces, and special characters. The "%" character is the wildcard for any symbol.
 - After you apply a filter, the count shows only the number of filtered objects.
To create a tree filter
 1. Open an existing AWS SCT project.
 2. Connect to the database you want to apply the tree filter to.
 3. Choose the filter icon.
 Note
 The undo filter icon is grayed out because no filter is currently applied.

 The filter icon for the schema tree
 4. Enter the following information in the Tree Filter dialog box. Options in the dialog box are different for each database engine.

 The filter icon for the schema tree
 AWS SCT option
 Action
 Schema/Database Name
 Choose the schema and database name you want to filter on. For schema name, you can enter "%" to choose all schemas.
 Object Name
 Choose the object name if you want to search by object name.
 Tree States
 Choose the table state. The options include the following:
 - Any – Show all tables.
 - Converted – Show only converted tables.
 - Not Converted – Show only tables that have not been converted.
 - Has Actions – Show tables with pending actions.
 Object types list
 Choose objects from the list of object types that you can filter on. Expand the tree nodes to load more objects to the object types list.
 5. Choose Apply. After you choose Apply, the undo filter icon (next to the filter icon) is enabled. Use this icon if you want to remove the filters you applied.
 6. Choose Close to close the dialog box.
When you filter the schema that appears in the tree, you don't change the objects that are converted when you convert your schema. The filter only changes what you see in the tree.
Importing a file list for the tree filter
You can import a file that contains names or values that you want the tree filter to use. In this file, the following convention is used:
 - Object is the type of object that you

In the last posting, we saw how Weibull analysis helped us to determine that SACM lead-free solder (SAC105 with about 0.1% manganese) has comparable (actually better) thermal cycle performance versus SAC305 solder. Software like Minitab will give us even more detailed information about the performance of the solder joints in stress testing as we see in Figure 1, above.
In addition to the Weibull plot, we also have the Probability Density Function (PDF), the Survival Function and the Hazard Function. The PDF tells us when it is most likely that a test board will fail in a test population, as shown by the inserted red line. We see that it is a little less than 2,000 cycles. The Survival Function shows the percent of surviving test boards. We observe that the expected life (the 50% point) is quite close to the maximum of the PDF. The Hazard Function tells us the rate at which the test boards are dropping out. It increases with time, but there are few boars left so the PDF drops down at the end of the test, even though the fall out rate is the highest.
It is interesting (and perhaps appropriate as Halloween approaches) to consider if human mortality follows a Weibull distribution. I used some data for the Centers for Disease Control that are a little over ten years old, for males in the US. So, the mean life expectancy is a little low at 72 years. (I was a little lazy, the old data were a little easier to work with than new data, some conversions are needed to make it work.) The data appear above in Figure 2.
As you can see, just like a solder joint, your life expectancy can be modeled quite well by the Weibull distribution.

A notable impediment has been the lack of critical biographies of significant thinkers in this tradition. The importance of personal and social context for reconstructing intellectual histories is widely understood. In the classical Indian intellectual tradition, however, authors systematically exclude such context, making intellectual biography something of a rarity — very rare in English and sparse even in the regional languages.
This book contains translations from the original Kannada of the biographies of Garalapuri Shastri, Shrikanta Shastri, and Kunigala Ramashastri of nineteenth-century Mysore, all representing the highest echelons of traditional panditya at this critical period of transition. Their fields are literature, grammar, and logic, respectively. The biographies focus on the personal lives of these scholars and their many contexts.
These biographies are almost contemporaneous accounts, reflecting first-hand knowledge. The translations are accompanied by copious footnotes as well as appendices drawn from the relevant primary sources.

How do I decide how many classes to take?
If you are an incoming frosh, we recommend signing up for 12-15 units of coursework in your first quarter. Keep in mind that adjusting to Stanford is at least the equivalent of a 3-unit course, so give yourself some room to breathe! After your first quarter, you can try taking on more if you like. In order to graduate in 4 years, you'll need to take an average of 15 units per quarter.
Important Deadlines
You will need to sign up for at least 12 units by the end of the first day of classes in order to be considered a full-time student. (See Also: What is a Unit?)
The official deadline to add and drop classes (Final Study List deadline) is the end of week three. However, while you can drop classes all the way through the third week, you should attend any classes you might take starting the first week of classes. Professors are often very reluctant to allow students to add a class that they have not been attending, and you may have missed work that cannot be made up.
After the third week of classes, your schedule for the quarter is set (the Final Study List deadline is 5pm on Friday of Week 3).
Things to consider as you choose the best combination
Number of classes
How many classes should you take? It depends. It depends on the classes, it depends on the workload, it depends on your other commitments, it depends on who you are and how you learn. This decision is best finalized after classes start--the ideal approach is to attend more classes than you expect to take, and by the end of Week 1, decide which of those classes make the best combination for you that quarter.
Typically, expect classes of 3-5 units to be main academic classes that can fulfill requirements and count toward a major, while classes of 1-2 units are usually lecture series or athletic classes, with fewer assignments outside class. Students will combine these in an infinite variety of ways.
12-15 units is ideal for your first quarter. The maximum number of academic units a first-quarter frosh may enroll in is 20. Students past their first quarter may request an exception to take 21 or 22 units in certain cases. See your Academic Advising Director or AARC advisor for details.
Cognitive shifting between types of studying/work often shows a better result than focusing in on one kind of learning. And it leads to less burn out. Most students do best with a balanced workload demanding a mix of exams and essays, of reading and problem sets, of STEM and humanities topics.
Four main academic classes may be nicely balanced among math, Spanish, chemistry, and history, but if you have two essays and two midterms all due in the same week, you might want to tweak something. It's useful to actually write down all the major deadlines on the Quarter-at-a-Glance planner, and then evaluate the commitments you are making.

The concept of environmental protection and low carbon has penetrated into every corner of the world. The use of recyclable and renewable energy has become a necessary design direction for every energy designer in the future. Recently, Ken Moffat, an energy designer in the United Kingdom, has developed an energy recovery system. It can provide pedestrians with electricity, so that the lights in the tiles shine, it is amazing.
This design concept makes full use of the power of the human footsteps and relies on this principle to convert the power of the footsteps into electrical energy. According to the designer, â€œWe have incorporated this very great concept into the lighting project of bricks and tiled the streets into the bustling streets. This will save the whole world a lot of electricity.â€ The project is currently on the Kickstarter website. Capital, and has already obtained a lot of fundraising. The project team Pavegen said, "If this fundraising is successful, we can apply this great invention to the world and change our world, so that every corner of the world is full of light."
Analysts said that if the "Pavegen Floor Tile" can be successfully listed, it will become a key research project for renewable energy. The future may be applied to a broader field to facilitate the grand plan of sustainable development.

Mathematics and Tensegrity
Group and representation theory make it possible to form a complete catalogue of "strut-cable" constructions with prescribed symmetries
Figure 9. Super stable tensegritiesClick to Enlarge Image
Tensegrity, a coined word describing a structure that retains its integrity under tension, is a concept developed by the American sculptor, Kenneth Snelson. The wonder and beauty of Snelson's sculptures surely lie in their three-dimensional nature. But these assemblies also pose interesting and difficult questions for mathematicians. Mathematically, what is a tensgrity? Why is it stable? Can tensegrities be classified or listed? The authors' recent work has aimed to find a proper three-dimensional generalization for tensegrities. Using the mathematical tools of group theory and representation theory, coupled with the powerful graphic and computational capabilities of computers, they have drawn up a complete catalogue of tensegrities with certain prescribed types of stability and symmetry, including some that have never been seen before.

Rawalpindi راولپݨڈى, commonly known as Pindi پݨڈى,, is a city and capital of Rawalpindi Division located in the Punjab province of Pakistan. Rawalpindi is the fourth-largest city proper in Pakistan, while the larger Islamabad-Rawalpindi metropolitan area is also the country's fourth-largest metropolitan area. Rawalpindi is adjacent to Pakistan's capital of Islamabad, and the two are jointly known as the "twin cities" on account of strong social and economic links between the cities.
The 16th century Rawat Fort offered military protection to Rawalpindi.
During the Mughal era, Rawalpindi remained under the rule of the Ghakhar clan, who in turn pledged allegiance to the Mughal Empire. The city was developed as an important outpost in order to guard the frontiers of the Mughal realm.Gakhars fortified a nearby caravanserai, in the 16th century, transforming it into the Rawat Fort in order to defend the Pothohar plateau from Sher Shah Suri's forces. Construction of the Attock Fort in 1581 after Akbar led a campaign against his brother Mirza Muhammad Hakim, further securing Rawalpindi's environs. In December 1585, the Emperor Akbar arrived in Rawalpindi, and remained in and around Rawalpindi for 13 years as he extended the frontiers of the empire, in an era described as a "glorious period" in his career as Emperor.
Sikh Misl
Sikh Empire
Sikh ruler Maharaja Ranjit Singh allowed the son of Sardar Milkha Singh to continue as Governor of Rawalpindi, after Ranjit Singh seized the district in 1810. Sikh rule over Rawalpindi was consolidated by defeat of the Afghans at Haidaran in July 1813 The Sikh rulers allied themselves with some of the local Gakhar tribes, and jointly defeated Syed Ahmad Barelvi at Akora Khattak in 1827, and again in 1831 in Balakot. Jews first arrived in Rawalpindi's Babu Mohallah neighbourhood from Mashhad, Persia in 1839, in order to flee from anti-Jewish laws instituted by the Qajar dynasty. In 1841, Diwan Kishan Kaur was appointed Sardar of Rawalpindi.
Rawalpindi's Fatima Jinnah Women University is housed in a Victorian mansion.
Following Rawalpindi's capture by the British East India company, 53rd Regiment of the company army took quarters in the newly captured city. The decision to man a permanent military cantonment in the city was made in 1851 by the Marquess of Dalhousie. The city saw its first telegraph office in the early 1850s. The city's Garrison Church was built shortly after in 1854, and is the site where Robert Milman, Bishop of Calcutta, was buried following his death in Rawalpindi in 1876. The city was home to 15,913 people in the 1855 census. During the 1857 Sepoy Mutiny, the area's Gakhars and Janjua tribes remained loyal to the British.
Rawalpindi and its environs, 1923.
Numerous civil and military buildings were built during the British era, and the Municipality of Rawalpindi was constituted in 1867,while the city's population as per the 1868 census was 19,228, with another 9,358 people residing in the city's cantonment. The city was also connected to railways that offered connection to India and the northwest frontier in Peshawar in the 1880s. The Commissariat Steam Flour Mills were the first such mills in Punjab, and supplied most of the needs of British cantonments throughout Punjab. Rawalpindi's cantonment served as a feeder to other cantonments throughout the region.
Rawalpindi's cantonment became a major center of military power of the Raj after an arsenal was established in 1883. Britain's army elevated the city from a small town, to the third largest city in Punjab by 1921. In 1868, 9,358 people lived in the city's cantonment – by 1891, the number rose to 37,870. In 1891, the city's population excluding the Cantonment was 34,153. The city was considered to be a favourite first posting for newly arrived soldiers from England, owing to the city's agreeable climate, and nearby hill station at nearby Murree. In 1901, Rawalpindi was made the winter headquarters of the Northern Command and of the Rawalpindi military division. Riots broke out against British rule in 1905, following a famine in Punjab that peasants were led to believe was a deliberate act.
During World War 1, Rawalpindi District "stood first" among districts in recruiting for the British war effort, with greater financial assistance from the British government channeled into the area in return. By 1921, Rawalpindi's cantonment had overshadowed the city – Rawalpindi was one of seven cities of Punjab in which over half the population lived in the cantonment district. Communal riots erupted between Rawalpindi's Sikh and Muslim communities in 1926 after Sikhs refused to silence music from a procession that was passing in front of a mosque.
On 5 March 1947, members of Rawalpindi's Hindu and Sikh communities took out a procession against the formation of a Muslim ministry within the Government of Punjab. Policemen fired upon protestors, while Hindus and Sikhs fought against weaker Muslim counter-protestors. The area's first Partition riots erupted the next day on 6 March 1947, when the city's Muslims, angered by the actions of Hindus and Sikhs and encouraged by the Pir of Golra Sharif, raided nearby villages after they were unable to do so in the city on account of Rawalpindi's heavily armed Sikhs.
At the dawn of Pakistan's independence in 1947 following the success of the Pakistan Movement, Rawalpindi was a 43.79% Muslim, while Rawalpindi District as a whole was 80% Muslim. The region, on account of its large Muslim majority, was thus awarded to Pakistan. Rawalpindi's Hindu and Sikh population, who had made up 33.72% and 17.32% of the city, migrated en masse to the newly independent Dominion of India after communal riots in western Punjab, while Muslim refugees from India settled in the city following anti-Muslim pogroms in eastern Punjab and northern India.
In the years following independence, Rawalpindi saw an influx of Muslim refugees, Pashtun and Kashmiri settlers. Having been the largest British Cantonment in the region at the dawn of Pakistan's independence, Rawalpindi was chosen as headquarters for the Pakistani Army, despite the fact that Karachi had been selected as the first capital.
In 1951, the Rawalpindi conspiracy took place in which leftist army officers conspired to depose the first elected Prime Minister of Pakistan, Liaquat Ali Khan. Rawalpindi later became the site of the Liaquat Ali Khan's assassination, in what is now known as Liaquat Bagh Park. In 1958, Field Marshal Ayub Khan launched his coup d'etat from Rawalpindi. In 1959, the city became the interim capital of the country under Ayub Khan, who had sought the creation of a new planned capital of Islamabad in the vicinity of Rawalpindi. As a result, Rawalpindi saw most major central government offices and institutions relocate to nearby territory, and its population rapidly expand.
Construction of Pakistan's new capital city of Islamabad in 1961 led to greater investment in Rawalpindi. Rawalpindi remained the headquarters of the Pakistani Army after the capital shifted to Islamabad in 1969, while the Pakistan Air Force continues to maintain an airbase in the Chaklala district of Rawalpindi. The military dictatorship of General Zia ul Haq hanged Pakistan's deposed Prime Minister, Zulfikar Ali Bhutto, in Rawalpindi in 1979.

book was created at that time, the "Angora Rabbit Book of France". In it, a French Angora rabbit type appeared, with a special fibre quality due to the breed (selection effect) and the harvest process (plucking and later defleecing). By 1988, there were about 250 000 angora rabbits, more than 2000 breeders and a production of fibre of 200 tonnes, exported as a raw material. In 1997, there were only 13 000 rabbits left, 100-120 breeders and a production of 12 tonnes for manufactured clothes.
Herd book "Angora Rabbit Book of France"
Created in 1956, the Herd Book is run by a breeders' organisation, the "Syndicat National Angora Qualité". The improvement of rabbit is done by mass selection. The breeders send a birth registration form for each litter and the animals are individually identified at weaning (provisional number). The animals are graded prior to their fourth harvest by a qualified judge and receive a final official number (ear tag). The breakdown of the total of 100 marks in the grading scheme is as follows: · 20 for body conformation (according to the official standard for body development, ears, head and legs) · 40 for fibre quantity · 40 for fleece quality, of which 15 marks are for homogeneity (bristly fleece rate), 15 marks are for tautness (intensity of bristly character) and 10 marks are for structure. On farm, data are registered on card for each animal, on which the harvest dates, weight of the harvested fibre (by categories) and fibre length are recorded.
Within the French breed, the harvested fibre is sorted and distinguished as 5 classes, according to quality: · Class 1: clean, unfelted, long and bristly fibre, from the back, the sides and the rump of the rabbit. · Class 2: clean, unfelted, long and wooly fibre, from the breast and the belly of the animal. · Class 3: clean, unfelted, short (<6 cm) fibre, from the legs of the rabbit. · Class 4: clean and felted fibre, from the neck and the tail of the animal. · Class 5: dirty fibre, from the underbelly of the rabbit.
Fleece characteristics measurements:
The Angora fleece is heterogeneous. Over the body, there are 5 different grades, whose quality criteria are based on the bristly or woolly aspect, length, the degree of felting and the cleanliness. Inside the lock, there are three fibre types, in which quality criteria are linked with the fibre dimensions and the fleece composition.
The fleece measurements made on the farm are the total fleece weight of each different grades and the length of each fibre type (bristle, downs). In the laboratory, the measurements are from the fleece samples, and they concern the diameter of each fibre type (bristle, awns, downs) by the OFDA method, and the content of each fibre type (bristle rate), using the INRA Cross Section method.
Breeding programme for Angora wool production
The breeding programme was orientated towards the effect of non-genetic factors on the quantitative and qualitative traits. The effects of the sex, birth season, body weight, harvest rank, harvest season, time interval between two harvests, breeder and the year on the total fibre production were quantified. The homogeneity and the structure of the fibre were taken into consideration. The results of this programme were as follows:
Genetic improvement of the French Angora Rabbit
One proposal is to have a collective programme, with a recording system for data collection and data transfer. It would allow both technical and genetic improvement, through selection on the farm and a collective genetic improvement programme. The latter could be done by creating genetic links between farms. The proposal would be to tattoo all the rabbits just after the first harvest and to score all the rabbits before the fourth harvest. On the whole population, the date of harvest, the total fibre weight and reproduction data would be collected. On the top selected population, it would be useful to collect data concerning the homogeneity, tautness and structure of the fleece (as an objective measurement of quality). Finally, connections between farms could be improved by setting up a performance testing farm and developing artificial insemination.

A GENETIC DATABASE FOR PERFORMANCE PARAMETER RECORDING IN DANISH ANGORA GOATS
Annette Holmenlund, Marie E. Kielsgaard and Joern Pedersen
Danish Agricultural Advisory Centre, Udkaersvej 15, Skejby, 8200 Aarhus-N, Denmark
The Danish goat registration system is a database storing data on pedigree, reproduction, growth rates, mohair yields, mohair quality and health. The database is based on an unambiguous identification system for individuals and on the farmers' own recordings of breeding and production data. The data stored in the database is used as documentation of pedigree, to estimate breeding indices and to produce management information for farmers. The Goat Registration System has been developed since 1991 and today 188 Angora herds are in the system, including 19 Swedish herds. The Nordic Angora goat population consists of many small herds. This is one of the reasons why we have developed a genetic indexation system over the past years, enabling us to compare animals from different herds and to find the best bucks and does in the Nordic countries. This will ensure the best possible basis for breeding progress and thus a profitable mohair production. How can we then incorporate more information about mohair quality into the goat registration system? This is one of the main questions to be dealt with in the next two years. We have defined two pre-conditions. Firstly, we would rather accept many quality figures and thus a higher degree of unreliability on the figures than vice-versa and, secondly, the method should be cheap, simple and user-friendly, in order to get full breeder support.
Since 1991, the Danish Angora goat breeders have reported their pedigree, breeding and production data to a computer-based goat registration programme, which stores all pedigree data on live animals and embryos imported since 1987. The purpose of goat registration programme is to develop a profitable mohair production, both through breeding and production, through the development of breeding values and management lists to the farmers.
One hundred and eighty-eight Angora herds, together with nineteen Swedish herds, are using the goat registration programme. In 1997, one hundred and thirty-three herds sent data about the births of 1400 kids from 1000 does. The breeding is characterised by many small herds with an average of 7.5 kidding per herd (1997).
The Angora goat population consists mainly of animals of the Australasian type imported from New Zealand. They are at present being upgraded using Angora of the Texas and South African types, imported in 1992 and 1993 from Australia and New-Zealand, respectively. The aim is to maintain the quality of the breeding work; it is achieved through the participation of the majority of the goat registration programme herds, which permits the data collection to continue.
The goat registration programme is being currently developed and the latest initiatives are the development of linear classification, breeding values (Pedersen, 1994) and "Herd Prints".
The goat registration system is based on an unambiguous nine-digit eartag number, which follows the animal from birth to death. It also includes the goat owners' own records of matings (inclusive of the buck's ID), kiddings (kidding ease, mortality, birth weight and ID of the kid), the kid's live weights at 2 and 4 months, all fleece weights, disease records, purchase, sale and deaths. Furthermore classification results and mohair test results are recorded.
All records are always linked to the unambiguous eartag number of the animal and to the date of the event, e.g. date of kidding and date of shearing.
From the goat registration system, the herd owner obtains:
The purpose of Herd Prints is that the lists can be adapted to the day-to-day needs of the individual farmer and they can replace some paper work.
Mohair yield and quality
Mohair production consists of two parameters, yield (quantity) and quality. The Angora herds report the fleece weights of every shearing which takes place twice a year - the first one being at the age of 5-7 months. A total of 8700 fleece weights is recorded in the database.
The quality of the mohair is measured objectively through a mohair test and subjectively through a classification scheme. The mohair test is analysed at the National Research Centre, Foulum and includes fibre diameter, standard deviation of the fibre diameter, percentage kemp, medullation and per-cent roundness. A total of 375 mohair samples has been analysed since it started.
The linear classification results are divided into a figure for body and legs, and a figure evaluating the mohair quality (fibre fineness, kemp and medullation, lustre, lanolin, style, character and cover). One hundred and fifty-seven animals were classified in 21 herds in 1995, when linear classification was introduced. In 1996, one hundred and seventy-five and, in 1997, ninety-four animals were linear classified.
As both mohair yield and fibre fineness are important economic production parameters, it is important that as many data as possible are collected on these two parameters. It would be a major progress if more

Protests in some instances are regarded as healthy especially when people have grievances that have not been handled for long. But peace must prevail for the protests to be regarded as worth. However, this is contrary to what most individuals think. The reason being that there is a feeling of been heard when chaos is involved. But is crucial that individuals understand that one's safety is crucial when it comes to making the protests. Hence, the necessity to view here for information that can help them learn more about ways of maintaining safety in a protest. Here, one is in a position to read more of ways to maintain safety during a protest.
The place in which the protest is to be conducted is the first factor to be discussed. Understanding this helps one avoid getting into trouble. Therefore, one can consider protesting on public forums such as the streets, sidewalks and even in the parks. Similarly, one can choose to conduct the protest in front of the buildings that belong to the government as long there is no blockage of activities in the buildings. It is advisable that an individual is keen to not protest in front of private buildings as the owners might file a claim against you.
The next way in which one can provide safety during a protest is by ensuring that the police involvement is put into consideration. This is crucial as police officers must appear to where individuals are protesting. Having peaceful protesting is the only way in which an individual can ensure that the police officers do not enforce the law to the protestors.
The next way in which individual can ensure that they are in a position to make good decisions. The informed among decision process helps an individual choose a protesting group that has good reasons to protest. It is crucial that one understands the plan that the protestor has. One should have the ability to choose a protest that individuals are speaking the same language. Informed decision-making process helps one avoid falling into bad situations.
In conclusion, one should ensure that they look into keeping the social distance. This is an essential aspect to ensure that they are safe from contracting airborne diseases that may be hazardous to their health. Most especially this time of the covid 19 pandemic, it is crucial that one wears a mask during the protest.

Big City Mountaineers transforms the lives of under-served youth through wilderness mentoring expeditions that instill critical life skills. We partner with community-based youth organizations and caring adult volunteers who act as mentors in the field to help young people realize their potential. Our curriculum improves self-esteem, responsibility, decision-making abilities and communication skills in close to 1,000 youth annually. BCM has a proven track record of improving young peoples' lives with:
- Increased likeliness to stay in school
- Reduction in violence
- Reduction in drug use
In addition to adult mentors who donate a week of their lives to improve the future of the youth we serve, we also rely on the support of our Summit for Someone climbers. Without the dozens of courageous volunteers who sign up for Summit For Someone each year, BCM would cease to exist. Our SFS climbers take on two formidable commitments: mentally and physically preparing to climb one of North America's most challenging peaks, and raising thousands of dollars. All to help improve the lives of kids they might never meet.
The team at Big City Mountaineers would like to thank all our colleagues in this endeavor: our volunteers, climbers and donors. Together we will continue impacting lives and delivering transformative wilderness mentoring experiences. Big City Mountaineers operates under special use permits from the USDA Forest Service and National Park Service, Big City Mountaineers is an equal opportunity service provider and employer.
The core Big City Mountaineers program is a week-long wilderness mentoring expedition where youth are given the opportunity to experience the beauty and challenges of the wilderness alongside supportive adult mentors. What had begun as a simple backpacking trip with at-risk teen 25 years ago has now evolved into a documented and well-tested progression of experiences coupled with opportunities for reflection and learning.
BCM Weeklong Expeditions:
- Provide wilderness mentoring opportunities to under-resourced youth ages 13 to 18.
- Cultivate relationships between youth and caring adult mentors.
- Offer a unique 1-to-1 ratio of adults to youth.
