The UniVec Database
UniVec is a database that can be used to quickly identify segments within nucleic acid sequences which may be of vector origin (vector contamination). Screening using UniVec is efficient because a large number of redundant subsequences have been eliminated to create a database that contains only one copy of every unique sequence segment from a large number of vectors.
In addition to vector sequences, UniVec also contains sequences for those adapters, linkers, and primers commonly used in the process of cloning cDNA or genomic DNA. This enables contamination with these oligonucleotide sequences to be found during the vector screen.
UniVec can be obtained from the NCBI FTP directory:
Eliminating the Redundancy from Vector Sequences
Many vectors have the same backbone or share common functional cassettes. Consequently, databases with the full sequence for each vector contain multiple copies of such elements. A single copy of each unique element is sufficient to allow that sequence to be recognized as vector contamination. The size of a database designed for screening can therefore be greatly reduced by eliminating the redundant copies of any sequence (see statistics for the current UniVec build).
The UniVec database is built by sequentially processing each input sequence. The input sequence is first compared to all the sequences already in the database. The location of any segment identical to database sequences is recorded. This information is used to extract only those segments of the input sequence that contain novel sequence. These novel elements are then added to the database. This cycle is repeated for each sequence that is to be represented in the finished database.
Benefits of a Non-Redundant Database for Screening
Elimination of redundant sequence segments reduces UniVec to less than 20% of the size of an equivalent database containing the full sequences for the same set of vectors. This has two major benefits for screening:
 - The computation time required to screen a query sequence is reduced significantly.
 - Analysis of the results is facilitated because redundant hits to multiple copies of the same sequence are largely eliminated.
Most vectors are circular, but their sequences are represented in linear form by opening the sequence at one particular location (the circular junction). Because programs such as BLAST are unable to extend a match across the end/beginning of the linear sequence, contamination with a segment of vector that spans the circular junction may be missed, or its full extent and strength may be underestimated. To circumvent this limitation, a copy of the first 49 bases of the sequence for a circular vector is appended to the end of the sequence before it is processed for addition to UniVec. This "pseudo-circularization" allows matches that span the circular junction to be identified correctly.
Vectors Represented in the UniVec Database
UniVec contains the unique segments, as well as a single copy of each of the shared segments, from all the vector, adapter, linker, and primer sequences that were used to build the database. The sequences used to build the current version of UniVec are listed in the current UniVec representation list.
Screening a query sequence against UniVec will result in the detection of significant contamination with any sequence from the current UniVec representation list. Contamination with vectors not on this list can also be detected if the vector is similar to one of the represented vectors, although in such cases the full extent of the contamination may not be reported.
UniVec will be periodically updated with additional vector sequences.
Send suggestions for additional sequences to include in UniVec to the NCBI Service Desk ( Please give a brief description of the vector or oligonucleotide, indicate where the sequence can be obtained, and provide references to a detailed description if available. Vectors and oligonucleotides that are commonly used for cloning and/or amplification will be given the highest priority for inclusion in future versions of UniVec.
Sources of the Sequences in UniVec
Most of the sequences in UniVec were derived from GenBank entries. In these cases, the parent sequence and annotation (when available) can be obtained from Entrez Nucleotide using the GenBank Accession number.version from the UniVec definition line.
The sequences for some commercial vectors, linkers, adapters, and primers that are not available in GenBank were obtained from company Web sites or product literature. UniVec entries derived from such non-GenBank sequences have a definition line containing an identifier of the form NGBxxxxx.x. The most up-to-date versions of these non-GenBank sequences, and in many cases annotations, can be obtained from the Web site of the company concerned.
Limitations of the UniVec Database
UniVec was built so that every unique sequence of 50 (or fewer) contiguous bases from the input sequences is represented in the database. Longer stretches of sequence are not necessarily represented as one contiguous piece in UniVec. This particular construction places certain limitations on the use of the database and on the interpretation of results from a search against the database.
Searches using UniVec will not indicate the identity of the vector having the strongest match to the query sequence. The full extent of the match to any individual vector will not be apparent because the sequence for most vectors in UniVec is not present as one contiguous piece. The most likely source(s) of vector contamination can be deduced from the cloning history of the sequenced DNA (more details are available in Interpretation of VecScreen Results). If it is necessary to identify the vector that has the best match to the query sequence, a BLAST search should be made using a database that contains a contiguous sequence for each vector, such as the artificial sequences subset of NCBI's nr/nt database.
UniVec should not be used for a search in which the criteria for a significant hit require an alignment of more than 50 bases.

Show your class
jQuery is great, no doubt. Using the famous JavaScript library copious adjustments of elements can be done with ease. Especially the manipulation of classes is a snap. While it requires multiple lines to toggle the class of an element with pure JavaScript, jQuery only needs a single one. But sometimes it might be a little bit over the top to utilize a whole library for just a single task. Beneath a bunch of other useful stuff HTML5 can also bear a helping hand here. A relatively new feature called classList API enables to add, remove and toggle classes with just a single line of code.
To add a class named error to an element whose ID is box:
To remove the same class:
To toogle a class called visible write:
Besides that the classList API also provides means to check if a certain class is present:
It checks if the element with the ID box has a class called red applied and returns true or false.
The support within modern browsers is pretty good, with Internet Explorer beeing the only family that can't deal with it so far. Luckily there is a polyfil that adds this functionality to unsupported browsers (unfortunately only starting from IE8).
First we have an element with the already familiar ID box:
This is a simple box
This element has some declarations applied:
_TAG_ {
 width: 200px;
 height: 200px;
 border: 1px solid;
 padding: 10px;
Additionaly there is another rule with the (non-semantic but very descriptive) classname red.
.red {
 background: red;
To add this class to the element a simple link with an onclick event-hadler is used:
Add color
A second link removes the red background:
Add color
If you want to summarize this functionality into one link use toggle:
Toggle color
Like you can see the classList API enables us to easily deal with classes – as long as an ID is present to address the element. If not it's still necessary to rely on jQuery or dig a little deeper into pure JavaScript. The excellent resource html5please.us brought my attention to this very useful API.


1,000-calorie lunch of 100 calories from the starter salad plus 900 pasta calories, or if they would eat 100 fewer calories of pasta, effectively canceling out the added calories from the salad.
In fact, the subjects consumed more than 200 fewer calories of pasta after the salad course. They consumed 100 calories from the salad and reduced pasta intake by 200 calories. In essence, one could say the salad had a net result of "negative" 100 calories. The Penn State study showed that preloading a meal with high-water, low-calorie-density vegetables can effectively reduce 100 calories from a meal.
The researchers repeated the experiment, adding a fatty dressing and extra shredded cheese, which quadrupled the salad's calorie density. Eating this higher fat salad as a first course did not result in a reduction in calorie consumption. Instead, the total calories consumed was over 1000. Studies on preloading show that eating about a cup of food with 100 calories before a meal decreases subsequent intake by about 100 calories. As such, to achieve a "negative calorie" effect, the first course would need to contain fewer than 100 calories per cup. Most fresh fruits and vegetables fall into this range, but a dinner roll, for example, does not. Figure 1 indicates the calorie density of some common foods.
When study subjects were given a large apple to eat before that same pasta meal, rather than consuming about 200 fewer calories, they consumed more than 300 fewer calories.(22) In effect, this means that the caloric "value" of an apple depends on when it is eaten. If consumed before a meal, it could essentially have a negative 200 calories due to the reduced intake in the main meal.
A similar result occurred when subjects were given vegetable soup as a first course: premeal soup consumption resulted in a dramatic decrease in calories consumed in the main meal. What's more, one study that tracked people's intake throughout the day found that overweight subjects randomized to prelunch vegetable soup not only consumed less at lunch, but intake at dinner 7 hours later was reduced by 100 calories as well.(23)
It has also been found that drinking 2 cups of plain water immediately before a meal resulted in a 20% reduction in food intake, resulting in more than 100 fewer calories consumed,(24) and overweight men and women randomized to 2 cups of water before each meal lost weight 44% faster than the control group.(25) So, "negative calorie" preloading—simply starting a meal with foods containing fewer than 100 calories per cup, such as many fruits, vegetables, soups, salads, or just a tall glass of water—may be able to accelerate the loss of body fat.
Foods That Enhance Weight Loss
How might that first-course salad boost weight loss even further? With the activation of an enzyme known as the "fat controller."(26) The discovery of 5′ AMP-activated protein kinase (AMPK) is considered one of the most important medical breakthroughs in the past few decades.(27) The enzyme can be activated through exercise,(28) fasting,(27) and nicotine,(29) and the pharmaceutical industry is investigating drugs than may activate the enzyme. Some persons with obesity may be "unwilling to perform even a minimum of physical activity," wrote a group of pharmacologists, "thus, indicating that drugs mimicking endurance exercise are highly desirable."(30) As such, according to a researcher, "it is crucial that oral compounds with high bioavailability are developed to safely induce chronic AMPK activation [for] long-term weight loss and maintenance . . ."(31) However, such a compound does not need to be developed. Vinegar is already readily available at any grocery store.
When the acetic acid in vinegar is absorbed and metabolized, a natural AMPK boost is achieved. In a randomized, double-blind, placebo-controlled trial on the effects of vinegar intake on the reduction of body fat in overweight men and women,(32) subjects were randomized to drink a daily beverage containing either 1 or 2 tablespoons of apple cider vinegar or a placebo developed to taste the same as the vinegar drinks but prepared with a different type of acid. Three months into the study, the placebo group gained body fat, whereas the 2 vinegar groups significantly lost body fat, as determined by computed tomography scan. Daily doses of only 1 or 2 tablespoons of vinegar (at a cost of pennies per day) led to significant weight loss without dietary change. For this reason, one might suggest 2 teaspoons of vinegar with each meal to accelerate weight loss, on salad or added to tea with lemon juice, for example.
The vinegar studies were not just randomized controlled trials, but placebo-controlled, as well. Some studies are not controlled at all. For instance, women asked to consume a ripe tomato before lunch every day for a month lost 2 lb, but without a control group, it is unknown what role, if any, the tomato played in the weight loss.(33) Simply being enrolled in a weight-loss study and knowing they will be weighed again in a month, for example, can motivate subjects to modify their diets.(34) Thus, although it is certainly possible that eating a tomato before a meal may contribute to weight loss, since it is 95% water and, as such, would effectively fill a fist-sized portion of the stomach with only about 15 calories,(35) a better study design is needed to assess its impact on weight loss.
More rigorous study designs include control groups. Subjects on a weight-loss diet randomized to 1 or 2 cups of low-sodium vegetable juice lost more weight than those given none,(36) for example, and when subjects in another study were randomized into 2 groups with 1 group given about 2 tablespoons of goji berries a day, those in the goji group lost 2.5 inches in waist circumference in 45 days, while the control group lost none.(37) Since the control group received no placebo, though, the placebo effect cannot be ruled out. However, some food items can be encapsulated, making double-blind, placebo-controlled trials easy to employ: spices.
For example, can garlic cause weight loss? Researchers gave subjects either garlic powder compressed into tablets or placebo pills and found that garlic resulted in a drop in both weight and waist circumference within 6 weeks.(38) The dosage used in the study was about 0.5 teaspoon of garlic powder a day, which would cost less than 4 cents. Even 2 cents' worth of garlic powder a day, 0.25 teaspoon, affected weight loss. About 100 overweight men and women were randomized to a quarter teaspoon of garlic powder a day or placebo, and those unknowingly taking the garlic lost about 6 lb of body fat over the next 15 weeks, significantly more than the placebo group (P = .02).(39)
Other common spices that have been found to facilitate weight loss include red pepper powder and ground ginger. Cayenne pepper can counteract the metabolic adaptation that results in a lower resting metabolic rate that accompanies weight loss(40) and also accelerate lipolysis,(41,42) and more than a dozen randomized controlled trials starting at only a quarter teaspoon of ground ginger daily showed significantly decreased body weight for just pennies a day.(43) Although ginger powder's efficacy has been demonstrated in placebo-controlled trials, these data remain relatively unknown, likely due to a lack of commercial potential.
For 3 cents a day, there is black cumin, which has shown much promise for weight loss and other health benefits."(44) A meta-analysis of randomized controlled trials shows weight-loss efficacy with a daily quarter teaspoon.(45) In addition to its weight-loss benefits, daily black cumin consumption has been shown in randomized controlled trials to significantly improve cholesterol and triglycerides,(46) blood pressure,(47) and blood sugar control.(48) A simple suggested use for the spice is to put black cumin seeds in a pepper grinder and flavor foods as one might with black pepper.
More than a thousand articles have been published in the medical literature on black cumin, with some reporting lowering cholesterol levels as much as a statin drug.(49) Why, then, are both the spice and its health benefits still relatively unknown? Why aren't students learning about black cumin in medical school? One reason may be insufficient profit motive. Black cumin is a common, natural spice that cannot be patented, and a useful dose can be bought for less than 3 cents a day.
Black cumin is distinct from regular cumin, the second most popular spice on earth,(50) which has also been found to be a weight-loss booster. Subjects randomized to a half teaspoon of cumin at both lunch and dinner over 3 months lost approximately 4 lb in weight and about an inch in waist circumference (P = .005).(51) The spice was found comparable to the obesity drug known as orlistat,(52) a drug that inhibits dietary fat digestion (and therefore absorption), which has the possible side effect of "anal leakage" if a low-fat diet is not consumed. The "anal leakage" drug sold as Alli,

Matters Needing Attention of Use Concrete Mixing Station
Brief Introduction：As the concrete mixing station management personnel, the daily management of the raw materials to control is very important.
Concrete mixing station is the main raw material of cement, cement varieties at home and abroad are: Portland cement, Portland cement, slag Portland cement, Portland cement Portland cement and fly ash Portland cement. So as a concrete mixing station, cement selection is very important. Under normal circumstances, according to the characteristics of cement, for large volume of concrete works should be used slag cement.
As the concrete mixing station management personnel, in the daily management of the raw materials to control is very important.
First, before entering the cement must do a good job with the inspection, there must be related to factory certification and laboratory reports.
Second, for a long time to keep the cement must be tested in advance, under normal circumstances the cement from the factory more than three months will be considered expired.
Third, in the production of finished products do not mix with different cement, for the same species of cement, the strength of different grades or different dates can not be mixed, as managers must bear in mind the above rules. At the same time sand, gravel and water and other raw materials is also very important, concrete mixing station in strict accordance with national standards to implement.
Managers must be the basic characteristics of concrete parameters in detail to understand the concrete mixing station of concrete strength to achieve the required level of requirements.

BTWSC in association with African Histories Revisted, focus their two 2013 NARM African British histories on commemorating the 50th anniversary of the Paul Stephenson-led Bristol Bus Boycott, and the 100th anniversary of the election of London's first African mayor John Archer.
Although the audio-visual presentations can be delivered separately for youths, adults and inter-generational audiences, the programme launches at Gayton library with a combined presentation. It consists of:
1. Paul Stephenson & The Bristol Bus Boycott
An audio-visual presentation led by history consultant Kwaku with primary source material highlighting the fact that there was a bus boycott in Britain in 1963. It's an accessible family-friendly presentation, which will also point out the connections with cricket, the first race relations law, Tony Benn, newly "independent" Caribbean states, and Martin Luther King's 'I Have A Dream Speech'.
2. John Archer & Black Politics
An audio-visual presentation led by history consultant Kwaku that goes beyond the fact that John Archer became London's first African mayor in 1913. It's an accessible family-friendly presentation, which will show that besides being a councillor, he was a Labour party activist whose successful collaboration with an Asian parliamentary candidate sowed the seeds of the party's Black Sections over half a century earlier. An attendee of the 1900 pan-African conference, he was talking about issues such as reparations, long before it took hold in the 1990s.

Pathways from land to stream: lessons from Pukemanga
In the Pukemanga catchment, nitrate is leaching from soil under agricultural land use, and is being transported by subsurface water flow to surface waters. Groundwater is the suspected dominant transport pathway. This study proposes to determine the proportion of groundwater discharge to streamflow by partitioning of daily and hourly streamflow on the basis of groundwater dynamics.

Numerical Simulation of the coupling efficiency for the light emitting from a commercially available ball-lens capped TO-can laser diode into a single-mode fiber (SMF) is reported. The alignment sensitivity of the coupling efficiency for this laser-to-lens-to-fiber optical configuration is investigated in detail. The result is useful for defining the design tolerances and assembly specifications of economic SMF pigtailed To-can laser diode packages. An optical simulation software package is used to compute the laser-to-lens-to-fiber coupling efficiency. By adjusting the nominal system parameters of the given optical configuration, the maximum coupling efficiency calculated from the best fitted simulation result being equal to 17.3% is obtained, which very well agrees with experimental result of ∼16%. However, it is a bit lower than that of previously reported. It is noticed that in the presence of the ball lens, the axial alignment sensitivity on the coupling efficiency is much relieved as compared to the butt-coupling configuration. However, the lateral alignment sensitivity is still very stringent. An experimental measurement is done on this optical system The alignment sensitivities of the coupling efficiency on both directions are obtained. The results are compared with that from the simulation. A very good fit of the data onto simulated curve can be obtained by adjusting some of the critical system parameters.

[Objective] This paper proposes a new model to process patent information based on machine learning classification algorithm, aiming to determine the level of invention. [Methods] First, we extracted the technology feature words from the patent texts. Then, we constructed the patent technology feature vector with an algorithm trained by Word2Vec. Third, we calculated patent text indicators and backward references to build the training set. Finally, we constructed the new model with machine learning classification algorithm. [Results] We retrieved patents in the field of speech recognition technology with the proposed model. We found that the proportion of advanced level to entry level patents was around 1:4, which was in line with the actual situation. [Limitations] The WordNet dictionary will limit the results of extraction. [Conclusions] The proposed model could effectively identify the advanced patents and recommend them to the business owners.

Abstract
Application of contraction theory provides a platform to analyze the exponential stability of nonlinear system. To effective compensate the time-varying parametric uncertainties exist in the longitudinal dynamics of the train, this paper proposes a contraction based saturated adaptive robust control for automatic train operation, which is subject to input limit of actuator. With consideration of actuator saturation, a recently developed robust modification is used to saturate the control input in each step, while the global stability is preserved. The resulting saturated adaptive robust control renders the transformed error enter the predefined region, furthermore, inside the predefined region, the contracting behaviour of closed-loop dynamics is regain and the tracking error exponentially converge to a residual set subsequently. The results of comparative experiments under different control strategies also verify the effectiveness of the proposed saturated adaptive robust control.

How do you subtract two timestamps?
The result of subtracting one timestamp (TS2) from another (TS1) is a timestamp duration that specifies the number of years, months, days, hours, minutes, seconds, and fractions of a second between the two timestamps. then %SECOND(RESULT) = %SECOND(TS1) – %SECOND(TS2).
Does SQLite support datediff?
SQLite does not have a DATE_DIFF function (handling dates is really tricking with SQLite). You can find some tricks about it on Stackoverflow.
How do I find the difference between two times in Oracle?
To calculate the difference between the timestamps in Oracle, simply subtract the start timestamp from the end timestamp (here: arrival – departure ). The resulting column will be in INTERVAL DAY TO SECOND .
How do I calculate hours between two dates in SQL?
To calculate the difference between the arrival and the departure in T-SQL, use the DATEDIFF(datepart, startdate, enddate) function. The datepart argument can be microsecond , second , minute , hour , day , week , month , quarter , or year .
How do you find the difference between two time?
To get the time difference in a single time unit (hours ,minutes or seconds), you can perform the following calculations. Total minutes between two times: To calculate the minutes between two times, multiply the time difference by 1440, which is the number of minutes in one day (24 hours * 60 minutes = 1440).
How do you subtract in SQLite?
The SQLite minus (-) operator is used to subtracting one expression or number from another expression or number. Here is the result. The SQLite multiply ( * ) operator is used to multiplying two or more expressions or numbers. Here is the result.
What is a correct time function in SQLite?
SQLite TIME() extracts the time part of a time or datetime expression as string format. The time() function returns the time as HH:MM:SS. Syntax: time(timestring, modifier, modifier.) Example-1: If you want to get the current time the following SQL can be used.
How do you find the difference in time between two columns?
You take one date away from another wich gives you the difference in number of days (including fractions). Multiply that value by the number of minutes in a day (24 hours * 60 minutes) to find out what it is in minutes.
How do I find the difference between two dates in SQL Developer?
Answer: Oracle supports date arithmetic and you can make expressions like "date1 – date2" using date subtraction to get the difference between the two dates.
How do you calculate total time in SQL?
Add hour-to-seconds, minutes-to-seconds and remaining seconds part into resultant @total integer variable. The second SELECT statement re-calculates the time parts (hour, minute, second) of the @total time in seconds. This sql calculation is simple. Take MOD to 60 of @total time for seconds.
How do I subtract two table values in SQL?
The Minus Operator in SQL is used with two SELECT statements. The MINUS operator is used to subtract the result set obtained by first SELECT query from the result set obtained by second SELECT query.

Lately, I have been loving a good fishtail braid. They are actually really easy to create and a beautiful way to wear your hair on a day you don't feel like drying it! Here are the steps to create one yourself:
1. Divide your hair into two large sections, parting straight down the middle. For a sharper look, you can use a comb to part your hair evenly.
2. Pull a thin strand of hair from the outside of the left section. Pull it over the top of the left section, and grasp it under the right section. Basically, the strand of hair has gone over the left section and finishes under the right section.
3. Repeat Step 2 on the other side. Pull a skinny strand of hair from the outside of the right section, pull it over the right section, then weave it under the left section.
4. Keep alternating sides, weaving over and under, until you reach the bottom of the braid.
5. Tie off the end with a hair bobble or elastic.


text: - We investigate the effects of weakly and strongly stratified turbulent convection on the mean effective Lorentz force, and especially on the mean effective magnetic pressure. Earlier studies with isotropically forced non-stratified and stratified turbulence have shown that the contribution of the turbulence to the mean magnetic pressure is negative for mean horizontal magnetic fields that are smaller than the equipartition strength, so that the effective mean magnetic pressure that takes into account the turbulence effects can be negative. Compared with earlier cases of forced turbulence with an isothermal equation of state, we find that the turbulence effect is similar to or even stronger in the present case of turbulent convection. This is argued to be due to the anisotropy of turbulence in the vertical direction. Another important difference compared with earlier studies is the presence of an evolution equation for the specific entropy. Mean-field modelling with entropy evolution indicates that the negative effective magnetic pressure can still lead to a large-scale instability which forms local flux concentrations, even though the specific entropy evolution tends to have a stabilizing effect when applied to a stably stratified (e.g. isothermal) layer. It is argued that this large-scale instability could be important for the formation of solar large-scale magnetic structures such as active regions.

Apus alexandri
Hartert, 1901
The Cape Verde Swift or Alexander's Swift (Apus alexandri) is a small bird of the swift family found only in the Cape Verde Islands. It has been recorded from all the islands except Santa Luzia although it probably breeds only on Santiago, Fogo, Brava, Santo Antão and São Nicolau. It is generally common with a stable population and is not considered to be threatened. It can be seen flying over all habitats and hunts in flight for insects, foraging in flocks over gullies and along cliffs and shorelines.
It is 13 cm long with a wingspan of 34 to 35 cm. The plumage is dark grey-brown with a large pale throat-patch. Compared to other swifts recorded from the islands it is smaller with shorter wings and a shallower fork to the tail. Its flight action is weaker and more fluttering. It has a high-pitched, screaming call with a buzzing quality.
The nest is built in a crevice in a cliff, in a cave or in the roof of a building. It is saucer-shaped and made of grass and feathers. The eggs are white and a clutch size of two has been reported.
The name Alexander's Swift commemorates Boyd Alexander, an English ornithologist who led two expeditions to the islands in 1897.

TUESDAY, Nov. 22 (HealthDay News) -- Some patients with inflammatory bowel disease may be at increased risk for skin cancer due to their use of immunosuppressant drugs to treat the intestinal disorder, according to the results of two new studies.
The studies, published in the November issue of the journal Gastroenterology, noted that immunosuppressants are commonly used to treat patients with inflammatory bowel disease, or IBD. Currently, there are no specific recommendations for skin cancer screening in IBD patients.
In one study, French researchers led by Dr. Laurent Peyrin-Biroulet, of University Hospital of Nancy, found that both past and present use of a widely used class of immunosuppressants called thiopurines significantly increased the risk of non-melanoma skin cancer in inflammatory bowel disease patients.
"The increased risk of skin cancer that we found in our study was observed in all patients, even before the age of 50 years. As expected, this risk increased with age. All patients with inflammatory bowel disease currently receiving or having previously received thiopurines should protect their skin from UV radiation and receive regular dermatologic screening, regardless of their age," Peyrin-Biroulet said in a news release from the American Gastroenterological Association.

Mineraloids
Interesting materials that fall short of meeting the definition of a "mineral"
Article by: , PhD, RPG
common opal
Common opal is a mineraloid. It is an amorphous silica with a chemical composition of SiO2.nH2O. It has a conchoidal fracture that is characteristic of an amorphous glass.
Opal
Precious Opal is a mineraloid. The play-of-color in opal is produced when light travels through a three-dimensional array of tiny silica spheres within the material. These tiny spheres serve as a diffraction grating that separates the light into its component colors. These spheres are very small and do not constitute an ordered atomic structure.
What Are Mineraloids?
A mineraloid is a naturally occurring, inorganic solid that does not exhibit crystallinity. It may have the outward appearance of a mineral, but it does not have the "ordered atomic structure" required to meet the definition of a mineral. Some mineraloids also lack the "definite chemical composition" required to be a mineral.
To be considered a mineral, a material must meet the following five requirements:
Minerals are "crystalline." In other words, they have an ordered atomic structure. In contrast, mineraloids are "amorphous." This means that their internal atomic structure is not ordered.
Without the ordered atomic structure, mineraloids never produce well-formed crystals. They also do not exhibit the property of cleavage because they lack internal planes of weakness.
ADVERTISEMENT
Obsidian
Obsidian is a mineraloid. It is a volcanic glass that cools so rapidly that atoms do not have time to arrange themselves into a crystalline solid. Instead, they form an amorphous, randomly bonded network.
Examples of Mineraloids
There are a number of familiar materials that can be classified as mineraloids. For example, opal is an amorphous hydrated silica with a chemical composition of SiO2.nH2O. The "n" in its formula indicates that the amount of water is variable. Therefore, opal is a mineraloid.
Obsidian and pumice are igneous rocks that solidified so rapidly from a melt that their atoms were unable to move into an ordered atomic structure. Instead, they rapidly formed a random network of atoms known as a "glass." Obsidian and pumice are amorphous, and their compositions can vary dramatically from one location to another and from one volcanic eruption to the next. Obsidian and pumice are also mineraloids.
Pele's Hair
Pele's Hair is the name used for hair-like strands of volcanic glass that sometimes form in areas where lava fountaining, lava cascades and vigorous lava activity occur. They are less than 1/2 millimeter in width, but can be up to two meters in length. They resemble golden-brown human hair in their size, shape and color. They are a mineraloid formed from basaltic lava. Creative Commons photograph by Cm3826.
Pumice
Pumice is an expanded volcanic glass. It forms during explosive eruptions of gas-charged magma. It is ejected from the volcano in a sudden blast and cools so quickly that bubbles of gas are trapped within the amorphous glass.
Tektite
Tektites are pieces of black glass formed by an impact somewhere between Australia and Southeast Asia about 800,000 years ago. The specimen in the above photo is a tektite from the Australasian strewnfield. Millions of tektites, ranging from sand-size grains to fist-size nodules, have been found in that area. Their surfaces are often marked with the same surface regmaglypts seen on iron meteorites.
Mineraloids from the Sky
Tektites and moldavites are varieties of natural glass that formed from the impact of an asteroid or comet. These objects struck the Earth at hypervelocity, and the force of their impact produced a tremendous amount of heat energy. The explosion that occurred upon impact flash-melted the target rock and produced a shower of molten material over thousands to millions of square miles. The molten material's temperature dropped quickly as it flew through the air - so quickly that the melts solidified without forming crystals.
ADVERTISEMENT
Libyan desert glass is a similar material thought to be caused by an impact in a sandy area. Fulgurite and the associated material known as lechatelierite are produced when lightning strikes the Earth in a sandy environment. These strikes instantly melt the sand, which then rapidly solidifies as amorphous silica. These materials are rapidly cooled glassy mineraloids.
Desert Glass
Libyan Desert Glass is a yellow glass found scattered over the desert near the border between Egypt and Libya. It is believed to have formed in the seconds after an asteroid impact about 29 million years ago. Large amounts of desert surface were flash-melted by the heat of the impact and scattered over the surrounding land.
Moldavite
Moldavite is another type of impact glass, which was formed about 15 million years ago when an asteroid struck the area that is now eastern Europe. The green glass is now found and valued by collectors. Transparent pieces with good clarity are sometimes cut as gems.
psilomelane
Psilomelane is a black hydrous manganese oxide that often contains barium and potassium. It is an amorphous material and an ore of manganese.

Mineraloid-forming Environments
Most mineraloids form at the low temperatures and low pressures found at Earth's surface and in shallow subsurface environments. Materials such as opal, psilomelane, chrysocolla, limonite, and a wide variety of supergene materials crystallize from gels or colloids in the shallow subsurface. Many of these materials will eventually transform into minerals with time, heat, or pressure. These low-temperature mineraloids often have a mammillary (smoothly rounded or hemispherical), botryoidal (grape-like clusters), pisolitic (pea-like clusters), or stalactitic (icicle-like) habit.
Mercury
Mercury is a liquid at room temperature, but when cooled to -38.8 degrees C, it crystallizes into a solid. Solid mercury meets all of the requirements of a mineral, and thus some people consider liquid mercury to be a mineraloid. Photo copyright iStockphoto / ados.
Limonite
Limonite is an amorphous mineraloid. It is a hydrated iron oxide.
Snowflake
Water is considered to be a mineraloid by many mineralogists. It crystallizes into water ice when cooled to 0 degrees C.
Can Liquids Be Mineraloids?
Water and mercury are often classified as mineraloids. They are the only two natural inorganic substances that have a definite chemical composition and are liquids at room temperature. They are also the only two liquids that crystallize into minerals within the range of temperatures and pressures encountered at Earth's surface. Water crystallizes into the mineral "water ice" when cooled to 0 degrees C. Mercury crystallizes into solid mercury at -38.8 degrees C. Due to the fact that they crystallize into minerals, some mineralogists include water and mercury in the mineraloids group.
radiolarite
Radiolarite is a sedimentary rock that forms from the accumulation of microscopic radiolarian tests and is thus of organic origin. This specimen is from the Windalia Radiolarite, a rock unit that formed on a marine shelf in an area that is now part of the Kennedy Ranges of Western Australia. When hard and tough it can be cut into cabochons, beads, tumbled stones, and other ornamental objects. It is sold as a gem material under the trade name "mookaite." Although it is a variety of chalcedony, some consider it a mineraloid because of its organic origin.
Mineral collection
The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties. Inexpensive mineral collections are available in the Geology.com Store. Image copyright iStockphoto / Anna Usova.
Organic Mineraloids?
If you read information about mineraloids written by a variety of authors, you will discover that some authors include organic materials, such as amber and jet, in their list of mineraloids. Some mineralogists agree with such classifications, but others feel this stretches the definition of a mineraloid too far.
Amber is a fossil plant resin found in sediments and sedimentary rocks in many parts of the world. It is hard, brittle, translucent to transparent, and is often cut as a gemstone. It has the appearance of a mineral, but lacks an ordered internal structure and lacks a definite chemical composition. Furthermore, it is organic. It fails three of the five tests for being a mineral. Should it be called a "mineraloid"?
Jet is a rare type of dark black coal. It has a smooth texture that accepts a bright polish, which is why it is often cut as a gemstone. It has the outward appearance of a mineral but lacks a crystalline structure and a definite chemical composition. It is also organic. Should it be called a "mineraloid"?
A number of very tiny organisms, such as diatoms and radiolarians, produce a thin shell of amorphous silica known as a "test." When these organisms die, their tests sink to the bottom. When the tests are the dominant material that accumulates, the sediment is known as "ooze." If buried and lithified, the ooze can transform into rocks such as diatomite and radiolarite. If they are composed of amorphous silica, should they be called mineraloids?

- addle (v.)
- 1712, from addle (n.) "urine, liquid filth," from Old English adela "mud, mire, liquid manure" (cognate with Old Swedish adel "urine," Middle Low German adel, Dutch aal "puddle").
Used in noun phrase addle egg (mid-13c.) "egg that does not hatch, rotten egg," literally "urine egg," a loan-translation of Latin ovum urinum, which is itself an erroneous loan-translation of Greek ourion oon "putrid egg," literally "wind egg," from ourios "of the wind" (confused by Roman writers with ourios "of urine," from ouron "urine"). Because of this usage, from c.1600 the noun in English was taken as an adjective meaning "putrid," and thence given a figurative extension to "empty, vain, idle," also "confused, muddled, unsound" (1706). The verb followed a like course. Related: Addled; addling.

Constable Street Community Allotment
Name of lead: Lausanne Tranter
Name of group/organisation: Constable Community Allotment / Friends of Constable Street Fields
Address: Constable Street, Hull, HU3 3DF
Open to the public? YES
What are the opening times? Always worth getting in contact first to check, as opening can be weather dependent, but in general: Fridays and Saturdays from 11:00am to roughly 4:00pm.
About Constable Street Allotment
This oasis of calm and quiet industry is based in the Boulevard area of Hull. The half-acre site is home to open veg plots, two large polytunnels, cob oven, iron-age inspired roundhouse and accessible composting toilet.
As well as an edible hedgerow, herb garden, small orchard, pond area and forest garden, there is an open meadow area that can be used for public events, teaching and workshops. They do not use chemicals or synthetic fertilisers and use permaculture principles to work in harmony with nature.
What was the inspiration at the very beginning?
Lausanne has been involved with Transition and Permaculture Hull for over a decade. Initially they took on a plot of unused land next to the Western Library on Boulevard. When the library was redeveloped, this land was taken over by Groundwork and now exists as the Western Library's garden.
The success of that first project led to the establishment of a small garden on Constable Street as part of the play area there, which then became a children's allotment. Unfortunately, this was prone to vandalism and theft, and the need for a more secure area to continue the work became apparent.
How has this changed over time?
A constituted group 'Friends of Constable Street Field' was formed, and an approach was made to Hull City Council to develop a derelict area next to the field that had been used to store building contractor's equipment. As it was already fenced, it provided the necessary security to be able to set up an allotment. The council were happy to oblige as the land had no further use, and gave them the keys to the gates. They have now been working on this site since October 2015, turning the disused half-acre site into a productive area growing fruit and vegetables. Approximately one year into the project, John Pickles joined Lausanne and provided much needed support and advice in developing the allotment into a multi-use space with a variety of different growing projects.
As a community allotment, it has been host to many events, including the annual Seed Swap and Hull Feastival. The meadow area is large enough to take small marquees, and has hosted music by Tenfoot Ukes and The Beats Bus during community open days. The focus has always been on growing and sharing advice and information, as well as providing veg
boxes (for a donation) and free food to those who need it. Engagement with the local community is at the heart of the principles of the allotment and they are always willing to teach people who have an interest in growing and food production.
Did lockdown have an impact?
They welcome volunteers, but like many other groups, could not open to the public during the lockdown period which means that much of the growing year for 2020 was lost. This has coupled with unusual weather conditions to produce vegetables at points where they should be going dormant over the winter period.
Despite this, they are now open to those who are interested, but need to observe COVID-safe protocols such as the rule of 6 in order to protect everyone's health.
Who do they engage with on a regular basis?
There are a small number of local residents who come to help out when they can, some of whom do it to benefit their physical and mental health through social prescribing.
Who would they like to engage with?
The desire now is to get more regular volunteers who can dedicate substantial time to help get the allotment back to how it was before lockdown occurred.
They would also like to see more children and young people attending, to spread the love of growing and eating different types of fruit and vegetable as well as feel they have a place they can come to that is a safe and welcoming space.
What are their aspirations for the future?
To secure continuation funding as the ultimate aim is for Constable Street Allotment to become a Permaculture Land Learning Site, and to be able to employ an assistant site manager who can work towards earning the Permaculture Design Certificate or Diploma. This would help establish the future of the allotment for future generations and be part of the sustainable food growing network within Hull.
They also want to further develop a veg box scheme that people can sign up to receive for a weekly/monthly donation. This would help cover basic running costs.

Let $\Omega:=\{(x,y,z)|x^2+y^2=1, 0\leq z \leq 2\}$, fix an $\alpha \in (-\frac{\pi}{2},\frac{\pi}{2})$ and given the transoformation $T(x,y,z):=(x,y+z\tan \alpha,z)$, find the volume of $T(\Omega)$.
Remark: By the coordinate transformation formula for multiple integrals one can compute the corresponding Jacobian to be $1$, thus the volume of $T(\Omega)$ is the same as the volume of $\Omega$, am I right?
Also, geometrically, the transformation only shifts the $xy$-cross section (at each $z$ level) to an extent (along the $y$ axis), thus the area of each cross section of the cylinder $\Omega$ remains unchanged after tranformation, so the volume of $T(\Omega)$ is equal to the one of $\Omega$.
Is my explaination correct?

Yes, the determinant of the (Jacobian) derivative tells the extent how the volume changes, and it is indeed $1$ in all points at this case ('tilting', or'shearing'), so the volume stays the same.
You can also convince yourself geometrically: by approximating the volume of the straight cylinder by small cubes (or rectangular solids), and then apply $T$, and a simple draw shows clearly that the tilted cube has the same volume as the orginal cube.

Tara Oceans Data Portal - Help
What Can I Use the TARA Data Portal (TOP) For?
TOP is designed to enable the community at large to lookup datasets containing data items related to experimental data collected during the TARA cruises. Dataset lookup can be performed by browsing according to various classifications or descriptions, but also using more advanced search forms. Whichever the means used to lookup datasets, the results will invariably be returned as tables listing matching datasets with their main properties. Each entry of these table is a link leading to a page detailing all that TOP knows about a dataset (who created it, who imported into TOP and when, what kind of data it contains, where the actual data file(s) can be found).
Can You Give Me Some Real Use Cases?
What is known about station TARA_054?
This can for example be determined by entering "TARA_054" in the quick search text field on the welcome page. The result table will contain a mix of datasets ranging from event log sheets to oceanographic context reports specific to station 54. And it will also contain more comprehensive datasets such as the sample registry and the event registry. Another means to achieve this is to go to the "Browse" page, select the "Sample Registry" tab and choose "TARA_054" in the "Stations" pull-down list (the Browsing section below gives some more detail about how to use this section).
What are the environmental parameters for samples collected at water temperatures between 18°C and 20°C?
Values for environmental parameters can be reached using the "Context/Environment Search" tab. In the form, the temperature values can be restricted using the sliders next to the "Tpot" field, and selecting the "Limited to" button left of the sliders before hitting the "Search" button. Results will be displayed in a table where each line matches a sample and each column corresponds to an environmental parameter.
What are the most recently uploaded datasets
Again, use the "Browse" tab. Select the "Date" tab immediately below. On the column headers of the dataset table, click on the "Last Update" header. The table will the be sorted according to the latest update date.
How to access datasets related to a given geographical area
This information is accessible using the "Advanced Search" tab. On the advanced search form, use the "Additionnal Criteria" drop-down menu to choose "Map". In the map panel that is the displayed, focus the map on the area of interest, then, use the icon next to "Map Mode" (located above the map) to switch to "Search Mode". It is then possible to draw a box on the map using the mouse. When hitting the "Search" button, teh result table will display datasets containing information about events and/or samples located in the box.

You can link together pairs of tools, so that changing the information displayed in one tool automatically updates the other. This can be done for virtually any tool in Common LispWorks, and provides a simple way for you to browse information and see how the state of the Lisp environment changes as you run your code. For instance, you can make between an Inspector and a Listener so that every time you evaluate a form in the Listener, its value is automatically inspected.
You can also link two copies of the same tool. This can be a very useful way of seeing two views of a tool at once. For instance, you could create a copy of the Class Browser by choosing Window > Clone, and then link them together. By keeping one browser in the subclasses view, and the other in the slots view, you can automatically see both the subclasses and the available slots for a given class.
Linked tools have a master-slave relationship. One tool (the slave) gets updated automatically, and the other tool (the master) controls the linking process. To link together any two tools:
To break a link, select -- No Link -- instead of a specific tool.
To view all the current links that have been established, choose Edit > Link from > Browse Links... Select any of the links listed and click on Remove Link(s) to remove them.

The cover-uncover test involves the patient fixating on an object, one eye is then covered and a refixation movement is looked for in the other - uncovered - eye. The other eye is then tested in the same way. If, during either manoeuvre, there is a movement of the unoccluded eye, then that eye must have been squinting before the fellow eye was uncovered, ie a manifest squint is present.

Jamie Bevan (CCW Warden of Crymlyn Bog and Pant-y-sias) wrote: 'Fen Raft Spider Dolomedes plantarius is currently showing well on the Tennant Canal, alongside Pant y Sais Fen. Known from only two other sites in the UK, it is one of Britain's rarest spiders. With a leg span of up to 7 cm, it is also one of our largest. It spends much of its time on a 'raft' of vegetation on the water surface, using its front legs to sense the vibrations of its aquatic invertebrate prey. It is even known to catch small fish such as sticklebacks! During the breeding season the female spider constructs a nursery web within the marginal vegetation, in which she deposits an egg sac. Hundreds of tiny spiderlings hatch out from the egg sac, which then develop inside the relative safety of the nursery web, before dispersing into the surrounding vegetation a week or so later. The female spider often guards the web while the spiderlings develop. This is generally the easiest time to spot this striking but elusive species. Look for the nursery webs in large sedge tussocks fringing the canal, and the attendant female is usually very close by.'
Ed. Note that there now is new boardwalk at Pant-y-sais that provides great access to the fen. This can be found by walking along the canal towpath from the Jersey Marine end, or off New Road (B4290) at SS/7128 9409. If you park in the old car park head sw along New Road for a couple of hundred metres.

Chronicle of Foreign Lands
The Zhifang waiji (Chronicle of foreign lands) is a concise geography of the world, the first of its kind written in Chinese. The Italian Jesuit missionary Matteo Ricci produced a map of the world in Chinese in 1584. The map, which followed Western principles of cartography then unknown in China, underwent several revisions between 1584 and 1602. Ricci's fellow priests Diego de Pantoja and Sabatino de Ursis were instructed by imperial order to compose a book explaining the map. Pantoja died in 1618 and the work eventually was completed...

Are Ouija Boards Dangerous? What to Know
Sally Painter
Ouija board
Are Ouija boards dangerous or is it all in your mind as some people argue? You can explore both sides of this discussion and decide for yourself if Ouija boards really are dangerous.
Are Ouija Boards Dangerous?
If you ask a psychologist, the answer is the Ouija board itself isn't dangerous, but the person with their fingers on the planchette might be. If you ask a medium, you will often get the same answer with a footnote: that it might not be the person that is dangerous, but a spirit.
Why Are Ouija Boards Dangerous?
There are many psychological reasons why a person might be dangerous as a result of using a Ouija board according to psychology professionals. The main one is the belief that the Ouija board is communicating with spirits. Psychologists believe a susceptible person may convince themselves that they are possessed by a demon.
Hands on a Ouija planchette
Psychological Dangers of Ouija Board
According to the mental health industry, the psychological dangers of Ouija boards rest with the mental health of the participants. Psychologists/Psychiatrists believe that psychic phenomena such as demonic possession, poltergeist activity, and hauntings by spirits are the result of various mental illnesses. This professional belief automatically displaces any supernatural or paranormal causes for the patient's condition.
How to Avoid Getting Caught Up in Superstitions
There are many creepy tales that circulate about the Ouija board, and it's easy to get caught up in the various superstitions about Ouija boards. The idea of communicating with spirits can feel spooky, and this creep factor can affect the most logical people when the planchette seems to move by itself by responding to questions. This can make you scared or even traumatized, so it's important that you stay grounded during a Ouija session. If you begin to feel afraid, then close the session and try again another time.
Ouija Board Gives Answer You Don't Like
You may ask questions you really don't want answered and start to regret it, especially if the information delivered by the Ouija board isn't true. For example, a participant may flippantly ask, "When am I going to die?" and the planchette slides to give a specific answer.
Avoid Asking Certain Questions
It's easy to avoid this type of response situation. Set guidelines prior to your Ouija board session about the type of questions prohibited. A personal guideline should be, if you aren't prepared to hear the answer to a specific question, then don't ask it.
Mediums Warn of Dangers of Ouija Board
Many mediums and Ouija board enthusiasts often warn of Ouija board dangers. They warn against playing with a Ouija board as though it were a game. They believe the board serves as a gateway to the other side where spirit dwells. Players are advised that it is very possible to invite disembodied entities to cross over and wreak havoc in their lives.
Scared woman
Safeguard Against Unwanted Spirits Lingering
The easiest way to prevent unwanted spirits from lingering long past the use of the Ouija board is to take proper steps to close the gateway at the end of your session. All you do is slide the planchette to "Good Bye" then turn it upside down with the feet pointing up. You should store the planchette upside down and wrapped in a cloth to prevent it from making contact with the board. For an added precaution, you can open and close each session by placing the room in protective white light and stating only those entities/spirits of the light can enter.
Dangers of Ouija Boards From Malevolent Spirits
Some mediums and psychics believe that only low frequency entities and spirits use Ouija boards as a form of communication. These beings don't vibrate at high enough frequencies to achieve communication any other way. This alone is a warning of the dangers of Ouija boards. These spirits or often demons are adept in deception.
spiritual portal
Why Low Level Spirits Are Dangerous
The low frequency beings using the Ouija board often pretend to be someone you once knew. The spirit may offer a few small truths to gain your trust. This information almost always takes a turn and becomes dark and misleading. By design, the communication can cause confusion, anguish, and even isolation.
How to Counter Ouija Board Misinformation
To mitigate any fearful information that comes through the Ouija board, take everything with a grain of salt. If you dislike the information you're receiving, end the session and try again another time. Never continue to communicate with an entity or spirit that makes you uncomfortable.
Malevolent Entities Waiting to Communicate
Many people believe malevolent entities are waiting to communicate with unsuspecting victims. One such being is called Zozo (also Zaza or Zuzu). Zozo is reported to be a negative entity that takes over sessions and seeks to wreak havoc in the life of any Ouija board user. While there is no proof Zozo is anything more than an urban legend or trick of the mind, many people have experienced the Zozo phenomenon.
How to Recognize Negative Entities
There are several telltale signs that you are communicating with a negative entity. Once you know what to look for, you can quickly end your Ouija board session. If you notice any of the following odd behaviors, immediately slide the planchette to "goodbye" and then turn it upside down. End your session and store the board appropriately.
 - Ouija board planchette slides to number 9 and counts backwards to 0.
 - Planchette slides between Z and a vowel repeatedly.
 - Planchette exhibits laughter by sliding back and forth between the letters H and A.
 - Planchette moves erratically.
 - Planchette cycles through the alphabet in either alphabetical or reverse alphabetical order.
You Become Emotionally Attached
If you are a frequent user, you can run the risk of becoming emotionally and psychologically attached to the Ouija board. This is especially dangerous if you rely on the Ouija board for advice and guidance in your life. This can lead to an obsessive behavior and even result in you shutting out friends and loved ones.
Upset man
How to Avoid Dangers of Ouija Board Attachment
You should constantly remind yourself that no game can dictate how you should live your life. You have free will and you live in the real world, not the world of a Ouija board. In spite of being consciously aware of these facts, you discover you're relying on the board in an unhealthy manner, seek professional guidance either through a mental health professional or a spiritual advisor, such as clergy.
Ouija Board Use Unleashes Psychokinetic Activity
There are anecdotal reports connected to Ouija board use about physical attacks and objects being thrown and smashed by unseen forces. In some cases, the activity continued even after the individual stopped using the Ouija board. This is known poltergeist activity.
How to Prevent Ouija Board Caused Poltergeist Activity
Poltergeist activity is caused by the phenomenon known as psychokinesis, which is frequently related to a living person although it can be generated by spirits. If you experience poltergeist activity during a Ouija board session, properly end the session and see if the activity stops. If it continues, you may need to help from a paranormal expert. In addition, you might need to talk with a therapist to resolve any residual emotional problems you have from the experience.
Demonic Possession Through Use of Ouija Board
The most frightening danger associated with the Ouija board is the possibility of demonic possession. This fear was heightened by the movie, The Exorcist, and the spirit Captain Howdy communicating through the Ouija board that led to the fictional demonic possession.
Possessed-looking woman
When to End Ouija Board Session
If any of the participants in the Ouija board session exhibits odd behavior, promptly end your session. You can perform a cleansing burn with sandalwood or other incense to clear out any negative energies. If it continues and you fear a demonic possession, infestation, or oppression, then you're dealing with a spiritual issue, not a paranormal one. You should seek help from clergy trained to deal with possession.
Ouija Board Dangers When You Believe It's a Game
Many people believe the Ouija board is just a game. This attitude makes them vulnerable to the dangers of Ouija boards. Communicating with spirits should never be taken lightly. You should be cautious when you use a Ouija board and make sure you are using spiritual protection techniques. Familiarize yourself with the signs of spiritual oppression. If, at any time, you feel the situation is out of control, any of the participants are uncomfortable, or you feel any sense of spiritual danger, end the session immediately using proper closing techniques.
Why Are Ouija Boards Dangerous?
A lack of respect for a divination tool, like a Ouija board, can make it dangerous to use. When you understand how to use a Ouija board and how to avoid possible dangers, it can be another tool for communicating with spirit.

To build a curriculum on positive deviance journalism for reporters and editors, and provide mentors to newsrooms helping them develop editorial strategies that look for positive trends in health data.
The Solutions Journalism Network seeks to broaden the role of journalism: it should not just uncover society's ills, but also report on responses to those problems. Founded by writers of the New York Times "Fixes" column, the Network works with newsrooms looking to include regular coverage of how communities, individuals and institutions are addressing challenges – and what society can learn from such efforts. Using this framework, the Solutions Journalism Network will collaborate with partner newsrooms and the Institute for Health Metrics and Evaluation to scan data sets for "positive deviance" in the health sector— examples of promising health results that could lead to important stories. For example, journalists in a city with large black/white disparities in preterm birth rates could identify cities that have reduced this gap, and report on how the gains were achieved. Expert coaching will help newsrooms find, vet, develop and write these stories.

Circling back to properties, when you set a value on an attribute or metadatum or author a relationship within a layer, you are effectively expressing an opinion on that value. This is named an opinion because value assignments can always be changed by others! This is a very important concept for composition.
A different way of looking at this would be that "setting a value" implies that that action is final and the value itself becomes immutable; whereas with opinions you merely mean
"Within this layer, I want the value for this to be
If the value already existed before, you are essentially "overriding" it

Aim : To verify the laws of combination (series) of resistance using a meter bridge (R=R1 + R2 )
Apparatus : a meter bridge, a leclanche cell (battery eliminator ), a galvanometer, a resistance box, a jockey, two resistance wire or two resistance coils, set square, connecting wires.
- The resistance (r) of a wire or coil is given by
Where R is the resistance from resistance box in the left gap and l is the length of the meter bridge wire from zero end upto balance point.
2. When two resistance r1 & r2 are connected in series, then their combined resistance
- Mark the two resistance coil as r1 and r2.
- To find the r1 and r2 proceed same way as in experiment 1.
(if r1 and r2 are not known )
- Connect the two coils r1 and r2 in series as shown circuit diagram in the right gap of meter bridge and find the resistance of this combination. Take at least three sets of observation.
- Record your observation.
Within limits of experimental error, experimental and theoretical values of R are same. Hence law of resistance in series is verified.
- The key should be inserted only while taking observation.
- Connections should be neat and tight.
Sources of error
- The key in resistance box may be loose.
- The galvanometer may not show opposite deflection.
|Resistance in R.B. (ohm)||Balance l (cm)||(100-l) (cm)||[(100-l)*R]/l||Mean r1 (cm)|
|Resistance in R.B. (ohm)||Balance l (cm)||(100-l) (cm)||[(100-l)*R]/l||Mean r2 (cm)|
|Resistance in R.B. (ohm)||Balance l (cm)||(100-l) (cm)||[(100-l)*R]/l||Mean rs (cm)|
R1 + R2 = 1.616+1.015 = 2.631 ohm
Rs = 2.615 ohm
Therefore, experimental error = [(2.615-2.631)/2.615]*100 = 0.6%
How does resistance change in series combination?
Ans. Resistance increase in series combination
Why does resistance increase in series combination?
Ans. Effective length of resistor increases. As R*l, resistance increases.
What is resistance?
Ans. it is the opposition offered by the material of two wire to flow of electric current.
What is the cause of resistance?
Ans. it is the opposition offered by the material of wire to flow of electric current.
What is the effect of temperature In the resistance of conductor?
Resistance of all conductor increases with increase in temperature.

What is a Mountain Leader?
The mountain leader is a graduate professional who leads a group (or alone) in the mountains. Unlike the mountain guide, the mountain leader evolves outside the techniques and tools specific to mountaineering. His field of intervention is the discovery of the mountain with different supports of progression. The mountain guide is a naturalist generalist and is primarily discovering the natural mountain environments, heritage and human.
Mountain leaders are organizers and hikers.
The professional activity covers three specific, identifiable but complementary functions: the guiding and management functions of the security of the practitioners; an educative and pedagogic action is also important and underlying in all of their activities (improvement of the physical and technical capacities of the practitioners); mediation for the discovery of the mountain environment in all its aspects (natural, heritage, human). Mediation and interpretation have for object the discovery, the understanding and the appropriation of the mountain environment.
To exercise this mediation action, the mountain guides have the choice between several supports: hiking, snowshoeing and, for some professionals, pack animals, mountain biking (additional qualification) or canyoning (AQA unique to this day issued in 1995).
Why touring in the Alps with a Mountain leader?
It's amazing! With a good knowing of his territory, he will be able to make you enjoy your time in an alp area in security. If you want to learn more about a specific topic, you will find a specialist for your tour.
