Twitter & Navigation - Coursework Example The following is the formula used to translate the coordinates: Decimal Degrees = Degrees + minutes/60 + seconds/3600 After configuring the degrees of the points the group must plot these positions on the paper map. The lack of identifying local landmarks or road signs in any case would cause issues with accuracy on pinpointing location. In order to avoid lack of accuracy a group should use some form of tracking device. For this project the iPhone is issued as a viable tracking device to be used secondary to the laptop. In reference to the project, a group encountered a problem when uploading data. The group had covered the laptop tracking device and could not retrieve a track record. The issued was solved by enabling the tracking system on the iPhone. The understanding that can be developed in this case is that the use of the paper map without assistance from electronics could be crippling. Utilizing a GPS as the main source for navigation and finding places has different outcome po ssibilities. Naturally coordinates have to be enabled on the system. This can be done by entering the same decimal degrees as map groups. The GPS will calculate and pinpoint these locations automatically. The tracking system within the GPS will develop a path for the group. However, the issue here can be based solely on the accuracy of the device. Should the pseudorandom code and the local copy of the coordinates be flawed by heavy error there will be destinations that do not match up. In the case of groups there should be a second record to show how accurate the findings are. In this case the use of a local map is implemented to show the right destination of the course. What can be picked up using the GPS method is that the accuracy of the device is hardly incapable of being disrupted. For that reason, individuals should not depend on one GPS result or test. A more accurate reading could be done if more than three devices are used. In general the use of a GPS system in combination with a map could be a suitable match. Though the project requires the use of paper maps and devices separately, they were typically used together to confirm information. The laptops were tracking as GPS devices would and the local area maps were a considerable replica of those paper maps. Twitter Twitter has an entire system is based on an Open System Environment. Currently, the users are implementing a Geo-tagging API to allow themselves to create TwitterVision, #UKSnow, and Trendsmaps in connection with Google Maps. With Geo-tagging one basically uses an iPhone (with viable signal) to deliver a corresponding coordinate to the system that transfers the iPhone signal into a location tag. Focusing more on the use of open systems can qualify the Twitter system to implement forums for educational environments and a larger scale of customer to business purchases as used in Second Life. The only major improvement that could be linked to the mapping system at present could be a location t o location open video attachment blog in real time to create a video conferencing concept. There is a current possibility of geo-tagging a video to a map using a camcorder that is GPS enabled. The basic concept is to utilize the available system the same as one would to geotag a photo (Catt 1). Should the concept of open software be generated to act as a system such as CISCO Webex there would be a live feed to connect universal Geo-taggers. This way individuals that use Geo-tagging for mapping could also enable real time video messaging

Wk 4 lab - Essay Example Justice for Davis and fair trial for Lewis and Karel.The splashing of whisky into Davis eyes was willful and intentional. But would the court treat alcohol as a weapon other than firearm? (California penal code section 245).Would it produce great bodily harm. If the answer is yes, then this is a felony charge with a sentence of up to 4 years and a fine of up to $10000, and not the $100000 compensation demanded by Davis.A compensation would preempt prosecution if they settle out of court. The use of violence on Davis by Karel leading to arm dislocation is a simple battery and can be charged as a misdemeanor or a felony. (California penal code section 242-243).There was body contact which led to injury, although no weapon was used. We can also contend that Lewis was a first offender with no record of violent temperament. We would also need to establish whether Lewis and Karel were intoxicated during commission of that offence, such that, we can argue on temporary insanity occasioned by intoxication. Even if these offences were committed in Malcolm parker’s premises, he is not the assailant and when push comes to shove, the assailants should be arraigned, charged, and sued for compensation and

Weathering in Empty Quarter in Saudi Arabia Essay

Weathering in Empty Quarter in Saudi Arabia - Essay Example Chemical weathering usually takes place in wet and moist climates, because of rain and interaction of chemicals in their soluble states. On the other hand physical weathering is common in deserts and arid regions, and main source of weathering in these areas is abrasion. Abrasion is defined as the process by which rocks or particles are reduced to smaller size and shape. Some basic types of physical weathering include thermal stress, frost weathering, salt crystal growth, pressure release, and ocean waves. The process of weathering is associated with erosion, which is simply defined as transfer of free particles from one place to another. Deserts exhibit both the phenomena, at one point there is abrasion, and the other point the weathered sand or rocks are carried away with wind, and then they are deposited. The process of deposition in sand results in the formation of sand dunes. There are four different types of sand dunes. They are Barchan, Star Dunes, Domal Dunes, Longitudinal Du nes, and Sand Sheets. The variation in dunes is due to their shape, size, location, and the direction of

Human Sexuality Paper Essay Example for Free

Human Sexuality Paper Essay When I was assigned this paper, I wanted to choose a paraphilia that I misunderstood the most. People who have sexual sadism disorder have frequent fantasies about sexual arousal results from inflicting psychological or physical suffering on a sexual partner, even humiliation and pain. This isn’t just a common act of rough sex. In the worst cases sexual sadism involves rape, torture, and even murder, the death of the victim produces sexual excitement. People who take their sexual addiction to these levels need psychiatric help or to be jailed. The arousal for these people is the terror in which they see in their victims. However, not all cases of sadism are so serious. Some are also people who do not torture so bad. This is known as sadomasochism. With this disorder, people are incredibly aroused by being tied up by their partner. Many normal couples use spanking, tying up, and a bit of force for fore play. This is not to be mistaken with sadism.. This is actually very common and kind of a fad now. There are sex stores that sell the type of products for this type of foreplay such as collars, whips, and all types of toys. There are a number of psychological theories about sadism. Most are based off of cases studies. Freud had two different views on the sadism. First he thought that aggressiveness with sexuality was urges. But he also thought that early in life children may have witnessed a sexual act or sex of their parents when they were just children. There were also psychologists that though that children developed sadism when their caretakers bring sexual pleasure and deny it when initiating toilet training or prevent asturbation. Psychologist sometimes believe that a person develops a psychological imprint during some earlier sexual experience at times.. Others believe that it is a slow process that relates back to when the individual becomes aroused and they then remember and reinforce it later in life during sex. A lot of men when asked are able to remember incidents in childhood or early adolescent that triggered them to become aroused. Treatment Someone with sexual sadism may never become known to the public, treatment or law enforcement. If people can limit their sexual sadism to istinct levels in a relationship, it is very controllable and not harmful if the partner is willing, which often can happen. For the ones who are brought to the attention of police officials the sadism has usually made itself into dangerous activity that have harmed others Conclusion In my thoughts, I feel that many and most people have sexual impulses that they are ashamed of. Most of which are not harmful, however, I do believe that individuals that are harmful to others need other resources and help with their condition to prevent the damage that is possible. Some hold in urges for so long that they are just simply uncontrollable in the heat of the moment. I feel any individual with these feelings need to seek counseling and try to pin point reasons and ways of subsiding their urges right off the bat. If the person affected is a serious danger to society then society needs to take serious measures to assure everyone’s safety. People who choose not to seek treatment could be just your average next door neighbor who looks and acts completely normal. And then suddenly one day they snap and become a danger to who ever is around them. This is concerning for everyone in society.

Tablet Direct Compression Methods

Tablet Direct Compression Methods Tablets are solid dosage forms usually prepared with the aid of suitable pharmaceutical excipients. The excipients can include binders, glidants (flow aids) and lubricants to ensure efficient tableting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive. They may vary in size, shape, weight, hardness, thickness, disintegration, and dissolution characteristics and in other aspects, depending on their intended use and method of manufacture. Most tablets are used in the oral administration of drugs. Many of this are prepared with colorants and coatings of various types. Other tablets, such as those administered sublingually, buccally, or vaginally, are prepared to have features most applicable to their particular route of administration. Tablets are prepared primarily by compression, with a limited number prepared by molding. Compressed tablets are manufactured with tablet machine s capable of exerting great pressure in compacting. Their shape and dimensions are determined by use of various shaped punches and dies. (Allen, Ansel and Popovich (2004)). In the tablet-pressing process, it is important that all ingredients be fairly dry, powdered or granular, somewhat uniform in particle size, and freely flowing. Mixed particle sized powders can segregate during manufacturing operations, which can result in tablets with poor drug or active pharmaceutical ingredient (API) content uniformity. Content uniformity ensures that the same API dose is delivered with each tablet. In early formulation studies, as a promising compound is characterized for biologic activity, it is also evaluated with regard to chemical and physical properties that have a bearing on its ultimate and successful formulation into a stable and effective pharmaceutical product. This is the area of responsibility of pharmaceutical scientists and formulation pharmacists trained in pharmaceutics. When sufficient information is gleaned on the compounds physical and chemical properties, initial formulation of the dosage form are redeveloped for use in human clinical trials. During the course of the clinical trials, the proposed product is developed further, from initial formulation to final formulation and from pilot plant (or small-scale production) to scale-up, in preparation for large-scale manufacturing. The dose of the drug may be described as an amount that is enough but not too much; the idea is to achieve the drugs optimum therapeutic effect with safety but at the lowest possible dose. The effective dose of a drug may be different for different patients. In a normal distribution sample, a drugs dose will provide what might be called an average effect in most individuals. However, in a portion of the population the drug will produce little effect, and in another portion the drug will produce an effect greater than average. The amount of drug that will produce the desired effect in most adult patients is considered the drugs usual adult dose and the likely starting dose for a patient. From this initial dose the physician may, if necessary, increase or decrease subsequent doses to meet the particular requirements of the patient. Certain drugs may produce more than one effect, depending on the dose. Drug doses vary greatly between drug substances; some drugs have small doses, other drugs have relatively large doses. The dose of the drug is based on its biochemical and pharmacologic activity, its physical and chemical properties, the dosage form used, the route of administration, and various patient factors. The dose of a drug for a particular patient may be determined in part on the basis of the patients age, weight, body surface area, general physical health, liver and kidney function (for drug metabolism and elimination), and the severity of the illness being treated. General dosing information for drug substances is provided in the monographs in the British National Formulary (BNF) as well as in the package inserts that accompany manufacturers pharmaceutical products. Again, these sources provide the prescriber and pharmacists with guidelines of usual dosage and usual dosage range. Optimally, appropriate drug dosage should resulting blood serum drug concentrations that are ab ove the MEC and below the MTC for the period of time that drug effects are desired. For certain drugs, a larger than usual initial dose may be required to achieve the desired blood drug level. (Stoklosa and Ansel, 1996) Active ingredients can be separated into two categories: low-dose and high-dose drugs. It should be technically possible to manufacture almost all drugs of low doses (less than 50 mg) by the direct compression process with a proper choice of excipients and tablet equipment. The term direct compression is defined as the process by which tablets are compressed directly from powder mixture of API and suitable excipients. No pretreatment of the powder blend by wet or dry granulation procedure is required. The problems encountered in direct compression of low-dose drugs centre around uniform distribution of the drug (blending) and possible unblending during the compression stage. Steps of Direct Compression Source: http://inferenceforqbd.com/Solutions/Pharmaceutical%20R+D.aspx Some granular chemicals, like potassium chloride, possess free-flowing and cohesive properties that enable them to be compressed directly in a tablet machine without need of granulation. For chemicals lacking this quality, special pharmaceutical excipients may be used to impart the necessary qualities for production of tablets by direct compression. These excipients include fillers, such as spray-dried lactose, microcrystals of alpha-monohydrate lactose, sucrose-invert sugar-corn starch mixtures, microcrystalline cellulose, crystalline maltose, and dicalcium phosphate; disintegrating agents, such as direct compression starch, sodium carboxymethyl starch, cross-linked carboxymethylcellulose fibers, and cross-linked polyvinylpyrrolidone; lubricants, such as magnesium stearate and talc; and glidants, such as fumed silicon dioxide. The capping, splitting, or laminating of tablets is sometimes related to air entrapment during direct compression. When air is trapped, the resulting tablets expand when the pressure of tableting is released, resulting in splits or layers in the tablets. Forced or induced feeders can reduce air entrapment, making the fill powder more dense and amenable to compaction. Capping also may be caused by punches that are not immaculately clean and perfectly smooth or by a granulation with too much fines, or fine powder. Fine powder, which results when a dried granulation is sized, is generally 10 to 20% of the weight of the granulation. Some fine powder is desired to fill the die cavity properly. However, an excess can lead to tablet softness and capping. Tablets that have aged or been stored improperly also may exhibit splitting or other physical deformations. In low dose formulation, advances in pharmaceutical research have resulted in the development of high potency active ingredients, which can be difficult to formulate into capsules or tablets. The use of Starch 1500HYPERLINK http://www.colorcon.com/products/core-excipients/immediate-release/starch-1500 ®HYPERLINK http://www.colorcon.com/products/core-excipients/immediate-release/starch-1500 partially pregelatinized maize starch as an active-premix in low dose formulations can provide consistent drug uniformity, which allows manufacturing by a direct compression process. Since many low dose medications are manufactured by a wet granulation method to assure each tablet contains the proper amount of active, switching to a direct compression process can result in substantial savings in total process time and cost. Comparison of wet granulation and direct compression methods Source: http://www.atacamalabs.com/technology_specialty Spray-dried lactose is the earliest and is still one of the most widely-used direct compression fillers. It is one of the few such excipients available from more than a single supplier. In spite of many early problems, this material revolutionized tableting technology. Coarse and regular grade sieved crystalline fractions of a-lactose monohydrate have very good flow properties but lack compressibility. However spray drying produces an agglomerated product that is more fluid and compressible than regular lactose. In the production of spray-dried lactose, lactose is first placed in an aqueous solution which is treated to remove impurities. Partial crystallization is then allowed to occur before spray-drying the slurry. As a result the final product contains a mixture of large a-monohydrate crystals and spherical aggregates of smaller crystals held together by glass or amorphous material. The fluidity of spray-dried lactose results from the large particle size and intermixing of spheric al aggregates. The compressibility is due to the nature of the aggregates and the percentage of amorphous material present and the resulting plastic flow, which occurs under compaction pressure. The problem of compressibility of spray-dried lactose is still real and troublesome. The compressibility of spray-dried lactose is borderline, and furthermore, it has relatively poor dilution potential. Spray-dried lactose is an effective direct compression filler when it makes up the major portion of the tablet (more than 80%), but it is not effective in diluting high-dose drugs whose crystalline nature is, in and of itself, not compressible. Furthermore, spray-dried lactose does not lend itself to reworking because it loses compressibility upon initial compaction. (Lieberman, Lachman and Schwartz). For the binders, there are many excipients that can be used. these include hydroxypropylcellulose (HPC), methylcellulose (MC), povidone (PVP), hydroxypropylmethylcellulose (HPMC), and starches and their derivatives, such as pregelatinized and granulated starches. These polymers differ in their physico-chemical, mechanical and morphological characteristics. For direct compression, studies suggest highly compactable, plastic, fine particle size binders facilitate compression of drugs at relatively low filler-to-drug ratios, therefore representing ideal properties for tablet binders (Drug Dev Ind Pharm. 1999;25:1129-35) (Drug Dev Ind Pharm. 2001;27:181-924). Tablet manufacturing by direct compression has increased steadily over the years. It offers advantages over the other manufacturing processes for tablets, such as wet granulation and provides high efficiency (Zhang et al., 2003). As direct compression is more economic, reducing the cycle time and straight forward in terms of good manufacturing practice requirements. Amongst the techniques used to prepare tablets, direct compression is the most advanced technology. It involves only blending and compression. Thus offering advantage particularly in terms of speedy production. Because it requires fewer unit operations, less machinery, reduced number of personnel and considerably less processing time along with increased product stability. Drugs characterized by high-dose, high bulk volume, poor compactibility, and poor fluidity (flow properties) do not lend themselves to direct compression. A typical sample would be paracetamol, an analgesic. The API of which is not easily compressed, then it require usually restricted to about 30% of direct compression formula hence tablet will costly and difficult to swallow. While it is possible to densify some drugs or formulations by preprocessing, there is some question as to whether the final tableting process could then be called direct compression. Paracetamol is high dose at 500 mg, is highly elastic and requires tastemasking. The taste-masking system to use is important for the active ingredient. If a finished dosage form has great taste, the consumer may prefer your tablet to another tablet solely based upon taste. If the product has an unpleasant taste, the consumer may discount speed of delivery and prefer better tasting slower tablets. The taste-masked API needs to survive the tabletting operation. It is inherently a poor compressible drug and high dose formulation can show capping and lamination. This can be attributed to the elastic recovery and brittle nature of the drug. Good tablet hardness (17kP), friability (30%) and elimination of capping and lamination were achieved with 7% HPC EXF binder level in the IR granulation and employing a pre-compression force of 3kN in addition to a main compression force of 25kN.(www.aqualon.com). Magnesium stearate dihydrate (MgSt-D) is a more effective lubricant for a high dose product containing 90+% COMPAPà ¢Ã¢â‚¬Å¾Ã‚ ¢ L at a high tableting speed. CONCLUSION As shown, there is a big difference in the formulation of low dose and high dose tablet. For the low dose tablet, an example is digoxin which is a cardiotonic, it is manufactured under direct compression since the powder mixture of the active pharmaceutical ingredient (API) is compressed directly with its excipients. Low dose means having a small amount of API, since there is a small amount of it, direct compression is the best possible way because when compounding a tablet, it is unavoidable that there will have some residue or some particles that can be left in the containers or when triturating. For the high dose tablet, an example is paracetamol, direct compression cant be use since high dose API are not easily compressed.

It is the national sport of most European and Latin-American countries, and of many other nations. Millions of people in more than 140 countries play soccer. The World Cup is held every four years. Soccer is one of the most famous international sports. Soccer is known world wide and is played in the Olympics. In a soccer game there are two teams of 11 players who try to score a point by kicking a ball into the opponents net. Soccer is played on a rectangular field with a net on each short side of the field. All players must hit the ball with their feet or body and only the goalie is allowed to touch the ball with his/her hands. There are many things you can do to condition yourself to play. Soccer the way we play it came from England in the 1800’s. Soccer was not that popular until the mid-1900’s. Today soccer is very popular and it is one of the nations fastest-growing sports. There are many exercises and drills you can do to improve how you play soccer. There is also many physical conditioning that players can do. Soccer can help you stay fit and healthy. Many people can play soccer and benefit from it. Soccer is very fun and a great recreational sport. History of the Activity Games similar to soccer were played in China as early as 400 BC. In about 200 AD the Romans played a game in which two teams tried to score by advancing a ball across a line on the field. The Romans passed the ball to one another but they never kicked it. London children in about 1100 played a form of soccer in the streets. During the 1800’s the people of England played a game similar to soccer. Many rules changed and each person interpreted the rules differently. In 1848 a group of school representatives met at Trinity College in Cambridge and drew up the first of soccer rules. In 1863 English soccer clubs founded the Football Association. By the late 1800’s soccer began to spread to the rest of the world. The Canadian Soccer Association was established in 1912 while the United States Soccer Federation was set up in 1913.
