World Economies Article Example | Topics and Well Written Essays - 250 words

World Economies - Article Example evident increases in purchasing power, global economies have been noted to potentially increase their products to America and other developed nations, which in turn, could further buoyed too much optimism of economic growth. The danger, according to the information, was that other economies could become too complacent and forget the fact that there are still other important economic aspects that need to be addressed. The perception of growth in world economies could apparently drive complacency to a point where more important economic reforms could be forgotten or stalled. One agrees with this assertion given that based on reported experiences on world economies, good news would usually put economic legislators into a momentary status quo since positive growth rates apparently indicate that economic measures have been effective in achieving economic targets. However, it could be deduced that the interconnected nature of world economies should put each economy into assuming a proactive stance at looking beyond current positive patterns and anticipating what these potentials could impact on future economic conditions. In fact, globally, the problem on jobs continue to exist and remain to be a persistent problem that needs to be addressed; despite positive patterns in various economic indicators.

Cyclic Scheduling Essay Example | Topics and Well Written Essays - 5000 words

Cyclic Scheduling - Essay Example ic scheduling in flexible manufacturing systems is something that has to be well understood by all those involved with production management and researchers have tried to develop a variety of heuristics and algorithms for solving cyclic scheduling problems in flexible manufacturing systems. Cyclic scheduling problems are often complex and require computational optimization techniques for their solution and automated systems with scheduling engines help production managers to find optimal scheduling solutions in real-time. This research paper presents a brief discussion about cyclic scheduling in flexible manufacturing. I hereby certify that, except where cited in the text, this work is the result of the research carried out by the author of this study. The main content of the study which has been presented contains work that has not previously been reported anywhere. Scheduling refers to the concept of allocating available resources over time to effectively plan for the execution of production orders in a manufacturing facility with its available processing machines and manufacturing systems (Lankford, Chapter 9.8). Depending on the demand for that which is being manufactured, a master production schedule will be made available and scheduling meets the requirements for production that are stated in the master production schedule. Thus, if automobiles or cellular phones are being manufactured in a facility, then the daily, monthly or weekly production output for the previously mentioned outputs will be mentioned in the master production schedule, as determined by the market or supplier commitments. However, the employed manpower, processing machine or production line capacity and material for production must be adequate for the required levels of production and this means that scheduling is about optimally assigning available resources to meet pr oduction targets. Thus, scheduling is more complex than the mere execution of jobs for production and depending on the

Neuroscience, Psychotherapy and Neuropsychotherapy

Neuroscience, Psychotherapy and Neuropsychotherapy Toni Killin Therapeutic strategies have been built from hundreds of years of experience. These strategies have over time proven their effectiveness for particular problems (Cozolino, 2010) (Grawe, 2007). The field of Neuroscience looks at brain structures and functions; it is a large field encompassing neurobiology, neurochemistry and areas of psychology. Neuropsychotherapy blends the fields of neuroscience and psychotherapy together. The emphasis being placed on the neuroscientific foundations of psychotherapy. Present rudimentary neuroscientific research findings offer psychotherapy scientific support, putting forward a new and fresh perspective for therapists. Neuropsychotherapy tries to remove the invisible barrier between mind and brain (Cozolino, 2010) (Grawe, 2007). Both the mind and brain are equally important, focusing on either one at the cost of the other would be to act as if one is irrelevant (Cozolino, 2010). My contact with clients and professionals such as therapists, psychiatris ts and psychologists led to my interest in Gestalt Therapy. Although my training in Gestalt Therapy is a passion, the journey has been a difficult learning experience. The experiential nature of Gestalt therapy has proven difficult for me to internally intellectualize. It has been this difficulty that led me to readings on neuroscience, as a way to understand, more fully, the mechanisms behind psychotherapy in general, in particular experiential modalities. These modalities reflecting good successes in areas that other modalities were appearing to be only mildly successful (Cozolino, 2010)(Grawe, 2007). I see this as an opportunity to have a deeper and different perspective on the therapeutic process and the therapeutic relationship. Consequently, this literature review will be divided into three sections. The first will give a rudimentary overview of what neuroscience is and the emergent findings within this field of psychotherapeutic interest. I will then relate neuroscientific findings broadly to the field of psychotherapy. Subsequently, I will relate some of these findings to some of the methodologies of Gestalt Therapy bringing findings from neuroscience together in the therapeutic relationship with a view to seeing Gestalt Therapy and psychotherapy in general from new and helpful vantage points. Given that neuroscience is a diverse field encompassing many professions, it is important to make the distinction that this paper will look at neuroscientific findings only in the context of psychotherapy and neuropsychotherapy. There are standardised professional differences not covered as part of this paper between clinical neuropsychologists, clinical neuropsychotherapists and psychotherapists that have good knowledge of areas of neuroscience that are of interest to the modality that they practice. Neuroscience is a complex area of study to define; it holds its place within all the sciences that deal with the nervous system such as Neurobiology, Neurochemistry, Neuropharmacology and Neuroanatomy. Neuroscience also draws on the knowledge found within many of the traditional disciplines such as Biology, which looks at the living matter in all its forms and phenomena. Biochemistry, the chemistry of living matter. Physiology a branch of biology that deals with functions and activities of living organisms. Pharmacology that delves into the preparation, uses and effects of drugs and Experimental Psychology which uses experimental methods to study mental and emotional activity in animals and humans (What is Neuroscience, 2012) (dictionary.com),(Stonehill College, Congregation of the Holy Cross, 2014). Neuropsychotherapy (NPT) is a term used to condense and combine neuroscientific knowledge in a variety of applications and treatments (Neuropsychotherapy.org, 2014). Neuropsychotherapists come from a wide range of medical and therapeutic backgrounds. A neuropsychotherapist is aware of the body-psyche interaction and uses their training and knowledge to carry out therapeutic assessments and treatments. Recent discoveries show that our experiences change the shape of our brain. Individual areas grow or change by adding miniscule amounts of the brain neural circuitry and eliminating old ones(Aherne, 2012). Knowledge such as this will help the evolution of more effective therapies, healthier connections will further recovery. This type of thinking challenges the metaphors of the past, visually perceiving brains as machines. Analogies made for computers with references to fixed circuitry and hardwiring (Doidge, 2011). Moving beyond the 20th century where the brain was modelled as a static perspective, we now see the brain as infinite in complexity. Essential regionalised connections are well distributed and integrated throughout the brain. Functions that were thought to be only in localised areas, now are known to participate with other parts of the brain(Fialkoff Jones, 2010) . New research includes exploring the interaction between neurochemical transmitters and brain cells, looking at previously unknown functions of neurons and glials, the most common cells in the brain(Fialkoff Jones, 2010) . There are four principles that become apparent to our understanding of the brain centers. The brain is complex, connected, adaptable (plastic) and evolved. The brain is adaptive, constantly rewriting itself. This ability to grow and change is referred to as plasticity. The brain not only creates new connections and develops greater physical space based on need, it also has the ability to erase old and unused connections (Doidge, 2011). The notion of a brain that can re-design its own form and function through thought and activity is profound. This is amongst the foremost important alterations of the brain since our understanding of basic anatomy and the functioning of its most elementary component, the neuron(Doidge, 2011). Like all revolutions, this has profound effects. The neuroplastic revolution has many implications, all areas that trade with human nature, such as our understanding of relationships, addictions, culture, learning and psychotherapies all change our brain. The humanities, social and physical sciences will all have to come to terms with the fact of the self changing brain. From person to person the brains architecture is unique and changes the course of individuals lives (Doidge, 2011). One of neurosciences most extraordinary discovery is that thinking, learning and acting can turn our genes on or off, thus sharpening our brain anatomy and our behaviour (Doidge, 2011). Brain plasticity is a very general term, applied to all ways that the brain is flexible and can process information in different ways (Buczynski,). A simplified example of steps in neural plasticity would begin with an inability in neurological functioning, this would lead to the founding of a secondary route. With use this secondary route finds shorter pathways and gets quicker and better at using these secondary neural pathways. With prolonged use and exposure t hese pathways continue to strengthen (Doidge, 2011). In the brain, there is an optimal point of plasticity at moderate ranges of arousal. Neural growth hormones and many of the processes that stimulate plasticity turn off at low levels of arousal, turn on at moderate levels, and turn off again at high levels (Buczynski,). This is important information when looking at encouraging new neural pathways. Creating an experience in therapy that results in neuroplasticity are to some degree a marker of successful therapy(Buczynski,). Another prominent discovery in neuroscience that is still getting attention is that of mirror neurons.Mirror neurons are â€Å"smart cells†(reference) laying down inner depictions within our brain and possibly our bodies. Mirror neurons permit us to comprehend the actions, intentions and feelings of others. These neurons, held in many parts of our brains, fire not only when we perform an action, such as holding hands, but also when when see others perfor m actions. Mirror neurons are not limited only to action, they are also stimulated when we experience an emotion and when we visually perceive others experiencing an emotion, such as pleasure, sorrow or distress(Lacoboni, 2008). Within the neuroscientific community mirror neuron research in humans has been polemic, no one piece of evidence being categorically accepted as proof that mirror neurons exist within humans. This however does not detract from the plethora of evidence supporting mirror neurons in humans (Keysers Gazzola, 2010) given technological reasons have thwarted the finding of individual mirror neurons (Vivona, 2009) supporting evidence has come from the electroencephalogram (EEG) recordings, behavioural experiments and transcranial magnetic stimulation (TMS) studies (Keysers Gazzola, 2010). In short research has shown that mirror neurons exist somewhere in the human brain and are not restricted to premotor and inferior parietal cortex. Research has also shown that c ertain neurons appear to have ‘anti-mirror properties. When these neurons work in combination with mirror neurons they could help the brain perform internal simulations of other peoples actions, simultaneously selectively blocking explicit motor output and remove ambiguities from who performed the action (Gallese, 2008) (Keysers Gazzola, 2010). Implications in psychotherapy Neuroplasticity does not always espouse uplifting news; our brains may be more resourceful, but are also more susceptible to outside impacts . Neuroplasticity can produce more flexibility, but also more rigid behaviours, this is called the â€Å"plastic paradox†(Doidge, 2011, p. 6), some of our most tenacious habits and disorders are products of plasticity. Once a particular plastic change occurs and becomes well established, it can prevent other changes from from occurring. Considering both the positive and negative properties of plasticity help us understand the extent of human possibilities (Doidge, 2011). In text reference Bibliography: Neuropsychotherapy.org.

The Psychology Behind the Serial Killer Essay -- Psychological Essays

The Psychology Behind the Serial Killer Creeping around the shadowy house, the predator found its prey waking to strange sounds. The victim lay facedown, with a sweating forehead pressed fearfully into the pillow, silently praying the noises would just go away. Suddenly the victim found himself straddled and pinned to the bed. He was unable to scream for help due to the pressure of the handle of a pick-axe against his throat, preventing any breath from escaping, much less any sound. The victim struggled beneath the weight of the assailant. The scant light from the sodium-arc street light outside cast a peculiar silhouette on the walls of the darkened room, projecting an image that looked oddly like that of a cowboy saddled upon a bucking bull at a rodeo. Struggling to dismount the attacker, the victim felt the piercing blows of the sharp point of the pickaxe, succumbing to death only after receiving eleven stab wounds to the chest and throat. The thrill of the kill was stimulating enough that, when interviewed later, the murderer reported â€Å"popping a nut,† that is, becoming so sexually aroused by the event, to the point of having an orgasm (Pearson, 1998). Does this sound like the heinous acts of Jeffrey Dahmer, Jack The Ripper, or Ted Bundy? How about the petite, pretty, fawnlike, Texas teen named Karla Faye Tucker? A woman? A killer? A sexual predator? Never before had such a thing been heard of, until Miss Tucker. Typically, when one thinks of serial killers, such images as Son of Sam, John Wayne Gacy, or the Boston Strangler, come to mind. Though these men do indeed fit the description, there are many myths and misconceptions surrounding the definition of serial killer, first and foremost that serial ... ...1998).

Micro And Nano Electromechanical Systems Engineering Essay

IntroductionIt is the procedure by which electricity drives all highly little mechanical devices. It consists of both electrical and mechanical constituents. Components are in the scope of 1 to 100 microns in size and due to its big surface to volume ratio electrostatics and wetting forces dominate. MEMS are fabricated utilizing semiconducting material device fiction engineerings chiefly used to fabricate smaller devices. MEMS is categorized as actuators and detectors. Detectors are non invasive whereas actuators are invasive and modify the environment. MEMS produce big figure of devices, which have indistinguishable belongingss, by batch processing. In aerospace field dependability is more of import compared to batch processing, as the ballistic capsule has to work for longer clip without failure. Miniaturization of electronics is brought about by decreased cost and mass production. These factors along with decreased size, weight, cost, detectors and actuators are used in miniaturis ation of electronics. Micro technology engineering will profit aerospace systems due to decreased size, mass and power demands. Batch fiction of MEMS brought about the revolution of incorporate devices [ 1 ] [ 3 ] [ 5 ] . MEMS integrate the non-electronic detectors with signal conditioning and digital logic electronics on a individual bit. Hence the constituents can be altered based on their on the job status. Actuators are chiefly used to command flux. In aerospace applications MEMS are inserted into micro propulsion systems, strain detectors, inertial gesture detectors, magnetic field detectors, force per unit area detectors, flow rate detectors and so on [ 1 ] .Few Instruments USED FOR AEROSPACE APPLICATIONSMicromachined air-breathing propulsors and actuatorsMEMS engineering has been used in the industry of solid-state propulsion, called the man-made jet. It is based on the construct of pumping the fluid in oscillating gesture. Actuator has a little hole in a pit. Volume of this pit can be modulated in an oscillating manner. To drive this volume of the pit any mechanical device can be used such that it operates at its resonating frequence. The construction is operated at its resonating frequence so that the drive amplitudes, which are achieved, are moderate. Sucking and blowing the fluid instead through a little hole is how the actuator operates. It should be take attention that the pump shot has a directed jet whereas the suction shot will pull fluid from all waies. Finally we see that the unstable drawn from the sides has low impulse and the fluid expelled upwards has higher impulse [ 2 ] [ 4 ] . The disadvantage of this device is that it is non really efficient as a device on the whole as the entire impulse imparted to the jet is really little. Man-made jets, which are fabricated by MEMS, have the undermentioned advantages i ) uniformity if the device is high and the losingss due to mechanical inefficiencies are reduced due to high Q public presentation of MEMS two ) push of the system can be increased by building arrays of actuators [ 2 ] [ 4 ] .NMP ST5 THERMAL LOUVERSThis looks at the flight proof of advanced micro sat engineerings that have non yet been flown to infinite so that the hazard associated with the hereafter NASA missions can be reduced. MEMS shutters have been developed for smart thermic control [ 2 ] .JWST MICROSHUTTER ARRAYJames Webb Space Telescope has developed a MEMS based microshutter array. This was developed near the spectrometer instrument. It is composed of for faculties with dimensions of 175 by 384 pels. This device is advantageous as these microsh utter are extremely selectively configurable in order to do usage of the NASA ‘s sensor. It is made out of Si nitride membrane [ 2 ] [ 4 ] .INCHWORM MICROACTUATORSThis is developed for extremist preciseness placement of the mirror sections in the ballistic capsule. This was chiefly developed utilizing the MEMS/NEMS engineering [ 2 ] .NMP ST6 INERTIAL STELLAR CAMERAIt combines MEMS inertial detectors with active pel detectors in order to do it a multifunctional bundle. This s used to take high-resolution exposures in infinite. It has embedded MEMS gyroscope [ 2 ] .MICROTHRUSTERSThese enable micropropulsive tactics for formation winging and besides the pointing of nano, pico and micro orbiters exactly. Without MEMS engineering being used for propulsion these devices can non fulfill the limited system mass and power restraints. MEMS engineering is used it provides the advantage of high denseness, low power and volume, big push degrees, quotable push vectors and integrating is sim ple. For MEMS we make usage of a Si substrate for fabricating [ 2 ] .Fabrication OF MEMS TECHNOLOGYMEMS fiction is a portion of the fiction engineerings. Traditional machining procedure uses big sum of diverse stuffs, 3-dimensional devices can be fabricate in order to bring forth precise devices. When we use MEMS fiction the stuffs used are more limited but little dimension devices can be manufactured. The fiction methods can be grouped into three chief classs. They are: Lithography, Galvanoformung, Abformung ( LIGA ) Bulk micromachining Sacrificial surface micromachining The last two procedures are silicon based. Bulk micromachining utilizations wet or dry etching procedures besides in order to bring forth isotropic and anisotropic stuffs. They produce MEMS structures that can be used for inertial detectors, force per unit area detectors and noses [ 3 ] [ 5 ] . LIGA – It helps to do complex constructions of metals, which are electroplatable, and holding high aspect ratios and thickness of several hundred micrometers. This procedure makes usage of ten beam lithography, thick resist beds and metals in order to organize complex constructions. The procedure starts by lodging a thin bed of sacrificial bed used for dividing the LIGA country from the country of the substrate after fiction. This has good adhesion and merely a think stuff will be sputter deposited. Titanium and Ni are the common stuff used for this procedure. X ray synchrotron is done following in order to bring forth walls over the thick resist to for a mask. Then we do electroplating of the base stuff after which shining is done. The sacrificial bed is removed in order to bring forth the LIGA portion. Magnetic propulsion is possible with this [ 3 ] [ 5 ] . BULK MICROMACHINING – The different countries that have to considered during etching is: Dissembling Selectivity of etch due to crystallographic orientation Etch halt and stop point sensing Endpoint sensing is used in order to command the deepness of the etch and besides to minimise the harm to the movies lying beneath. Plasma etching is best suited for this procedure [ 3 ] [ 5 ] . SACRIFIAL SURFACE MICROMACHINING – This method is holding its roots on deposition, modeling and etching of stuffs on a substrate. They will hold alternate beds of sacrificial and substrate stuff. Sacrificial bed is removed towards the terminal of the procedure, which consequences in a mechanical construction. An anneal is required in order to cut down the degrees of emphasis. The MEMS micromachines are much larger and thicker compared to the microelectronic devices [ 3 ] [ 5 ] . MEMS bundles for aerospace applications – these bundles are used in order to minimise the size, cost, mass and complexness of the system. It helps to supply interface between the overall system and the constituents. These bundles must run into demands such as thermic cycling, humidness, high temperature operation, radiation and daze to call a few [ 3 ] [ 5 ] . MECHANICAL SUPPORT – This is extremely mechanical in nature hence it has to be protected from high acceleration, mechanical daze, radiation and other physical amendss associated with it. This depends strictly on the applications like when a ballistic capsule lands on the planet ‘s surface it will see greater mechanical daze than any other ballistic capsule. Coefficient of thermic enlargement ( CTE ) of the MEMS bundle should be equal to or greater than CTE of Si on order for it to be dependable. The thermic parametric quantities can ensue in delamination or decease checking if there is any job with the Si or emphasis. After CTE job is take attention of the following thing to be considered is physical harm [ 3 ] [ 5 ] . Protection FROM ENVIRONMENT- MEMS packaging has to be protected from physical harm and besides when it is packaged during fiction and before it is sealed. Main attention has to be taken because of its reaction with wet as it causes the stuffs to swell, emphasis and delaminate. Hence, these bundles need to be hermetic with the sidewalls, base and palpebra in order for high dependability. They should be constructed from stuffs that can move as good barriers to liquid and gases and besides they should non pin down gases. Some MEMS french friess require vacuity conditions in order for it to run decently [ 3 ] [ 5 ] .

They can hold big internal volume but still dependable. Package will hold integrated sidewalls and base with palpebras. Materials are mainly metals like CuW, which have good thermic conduction, and higher CTE compared to silicon. Trapped gases should be removed invariably as it reduces failures related to corrosion. Au-Sn solder is used when stuffs have to be bonded. Welding can besides be used alternatively of solder. The metallization procedure allows for wetting the conducting pin wholly to the ceramic. Incomplete wetting consequences in failure during proving [ 6 ] [ 7 ] . CERAMIC PACKAGES – These have low mass, cost and can be produced in majority. These can be made hermetic and can execute different map. When we incorporate multiple beds of ceramics and interconnect lines, electrical public presentation of the bundle will run into the design demands. On each movie a metal bed is deposited utilizing thick movie processing and holes for interconnects are drilled. After these beds are fabricated the portion is fired at high temperature and MEMS and other constituents is attached to it. Many factors should be take attention of in this bundle that is the sum of holes, shriveling beds, treating temperature and ceramic belongingss. Frequently used metals are W and Mo. Normally used music directors are Ag, AgPd, Au and AuPt [ 6 ] [ 7 ] . THIN-FILM MULTILAYER PACKAGES – Two engineerings are used. First uses polyamide sheets, which are laminated together. Second, polymeric amide is used in this instance besides but each bed is spun onto and baked on carried to organize beds. In this method we use etching. The polymeric amides have lower permittivity so it has low line electrical capacity, which consequences in faster circuits [ 6 ] [ 7 ] . Plastic PACKAGES – These have lower fabrication cost. These are non extremely dependable and are non anchoritic in nature. These bundles are susceptible to checking in humid environment. Hence these bundles have non gained much importance [ 6 ] .EXAMPLE APPLICATIONS OF MEMS FOR SPACEMEMS devices used for infinite applications have reduced weight, cost, size and power ingestion. Common detectors and actuators used are accelerometers, gyroscopes, gaussmeters and spectrometers.VARIABLE EMITTANCE COATING INSTRUMENT FOR SPACE TECHNOLOGY 5The tegument on the orbiter where we need to maintain the MEMS based thermic control is called variable emittance surfacing instrument. This consist of 2 parts I ) MEMS shutter array radiator ( MSA ) and electronic control unit ( ECA ) . MSA located on bottom deck of ballistic capsule whereas ECA located within the ballistic capsule. Consists of arrays in the order of 150mm long and 6 millimeters broad shutters and are driven by electrostatic combs . Device exposed to the radiator and substrate should be thermally and electrically coupled to the radiator so that heat is allowed to reassign and electric charging is prevented. A polymer called CPI, which is both transmissive and electrically conductive, is used to extinguish the jeopardies due to environment. A 4mm movie midst is sandwiched and bonded. CPI movie is suspended above shutters and Acts of the Apostless as a barrier between MEMS and environment. Coating of InSnO2 is applied to for electrical conduction [ 7 ] .FLAT PLASMA SPECTROMETER FOR THE USAFA FALCONSAT-3MEMS fiction helped in doing usage of level plasma spectrometer ( FIaPS ) , which provides finer declarations and angular distributions. FIaPS was placed on the orbiter which will so mensurate the ion spectra derived function in energy. This instrument includes a PCB, power supply, detector caput array and human body. Sensor caput is fabricated and assembled, it consists of an array of indistinguishable spectrome ter faculties and an anode home base for sensing. This consists of three beds of Si and two beds of Be Cu. Five beds are stacked instead. CuBe home bases were used for preciseness to accomplish array of channels. Each Si had 5 dies. Wafer was diced such that each of the five dies are bonded separately to the CuBe home bases. The remainder of the points were assembled and packaged into ballistic capsule interface lodging unit utilizing many prison guards. Bonded constituents of detector caput used iridite plated aluminum rods for maintain the MCP [ 7 ] .MICROMIRROR ARRAYS FOR THE JAMES WEBB SPACE TELESCOPE ( JWST )JWST is equipped with mutiobject spectrometer, MEMS mirror arrays which acts as a slit mask for the spectrometer and selectively direct visible radiation from different parts in the infinite to the spectrometer. CMOS driver bit was designed. Large french friess are bonded onto Si substrate to extinguish emphasiss due to mismatched coefficients between the bit and substrate. CMOS assembly was put inside the bundle utilizing peripheral force per unit area contacts [ 7 ] .MICROJET JET ENGINESThis is a micromachined actuator used for propulsion and energy transitions. This device is being developed presently consists of a compressor, burning chamber and turbine. It uses H as its fuel. High aspect ratio of this device is obtained utilizing reactive ion etching ( RIE ) which is an advanced method of MEMS engineering [ 7 ] .Detectors and Actuators in Aerospace ApplicationsDetectors are used in assortment of aerospace applications like set downing cogwheel, ice protection. Measuring of fuel and pilotage. Modern airplanes have automated cockpits and a batch for information about the aircrafts tallness, velocity, temperature and cabin force per unit area is given by the array of detectors in it. These vehicles besides have automatic pilotage due to inertial counsel systems and conditions updates are given continuously. These detectors are utile in meteoric face ts to cognize more about the conditions [ 7 ] . The usage of MEMS in aerospace systems is extremely application particular and reduced the size, power ingestion and weight at the constituent degree. The cost and advantage and electronic integrating capacities of MEMS will assist in leting distributed measuring and propulsion. This helps in cut downing size, wet content and it becomes more vulnerable and dependable [ 7 ] .DecisionHere we have seen a big figure of packaging applications that ‘s have been used by MEMS devices in infinite applications. In the semiconducting material industry, these bundles are the lone devices that can protect devices from radiation and this holds for packaging of MEMS device. These actuators and detectors need to be exposed to the environment to execute their original maps ; besides due to the individualism of MEMS devices, there is no general bundle solution, every device requires its ain bundle attack of MEMS. The bundle needs to protect the device from all the environmental conditions. Humid and wet content has to be taken attention of decently for MEMS bundles to be dependable. There been many chances to turn out how utile these bundles are in the flight and infinite applications. In order to larn more about MEMS applications many more flight chances should be made [ 6 ] .

Cultural Diversity in the Media Essay

The term drugs refer to anything, which is not prepared by organisms and is generally considered that drugs are not part of food we eat. Although drugs also refer to Medical ailments (pills, syrups, capsules etc) but here we are discussing recreational drugs which are: LSD, Shrooms, Alcohol, Caffeine, Catnip, Salvia, Cocaine, Crack, DXM, Ecstasy, Ephedrine, Heroin, Inhalants, GHB, Tobacco, Cannabis, Methamphetamine, Milk (artificially prepared), Peyote, Nutmeg, Oxycontin, Ketamine, Whiteboard Markers and so on. Drugs have its uses and abuses. But mostly, its uses are almost negligible when one starts introspection of the conditions of society caused by the abuses of Drugs. Societies are damaging because of evils of the alarming increase in the intake of drugs all over the world, which is followed by the increase in crime and decrease in national income. It has been surveyed that people portray abnormal, illegal and ruthless behaviors after intake of drugs. Alcohols being widely available in societies of west provide easy hand in the provision of drugs. In America alone, every third child is said to be tainted by the drugs. All teens see some type of drug use or abuse in school or in the media. â€Å"The nineteenth-century explosion of drug use had gotten out of hand. Wiliam Halsted invented nerve-block anesthesia with cocaine (1885) but developed such a craving for the drug that his friends had to put him aboard a schooner for several months so he could kick the habit. He did, but became addicted to morphine from the ship’s supplies. It was long a closely guarded secret at Johns Hopkins University that one of the institution’s founders was a junkie. Halsted’s student, James Leonard Corning, invented spinal anesthesia with cocaine. Every family has a vicious drunkard dad or uncle on the loose; mournful mamas swigged patent medicines by the gallon; kids raised on heroin cough syrup graduated to coca-filled soft drinks. † Increasing display of drugs as element of â€Å"Being cool†, â€Å"Easy money†, â€Å"Failure in love†, â€Å"Family problems†, â€Å"Peer Pressures† and â€Å"Complexes†, in movies is grasping the attraction of teens and young adults. â€Å"An estimated 66. 5 million Americans 12 years or older reported current use of a tobacco product in 2001. This number represents 29. 5 percent of the population. Youth cigarette use in 2001 was slightly below the rate for 2000, continuing a downward trend since 1999. † Rates of youth cigarette use were 14. 9 percent in 1999, 13. 4 percent in 2000, and 13. 0 percent in 2001. The annual number of new daily smokers age 12 to 17 decreased from 1. 1 million in 1997 to 747,000 in 2000. This translates into a reduction from 3,000 to 2,000 in the number of new youth smokers per day. † Some of the most important movies to display drugs as an inspiration for live life, business and culture are given with their detail account of criticism and background. 1. The Blow The Blow was released in 2001 was based on a true story. The story of George Jung, the man who established the American cocaine market in the 1970’s. It was directed by Ted Demme. The screenplay is by Nick Cassavetes and David McKenna. It is story of young man of middle class family struggling for a better place in society, which unfortunately do not turn out be very fruitful for the fate of the family. George then moved to California, where he starts his own business in which he finds both success and imprisonment. In prison, he meets a cellmate who introduces him into a partnership to the lucrative new market in cocaine. When George Jung released from jail he quickly becomes instrumental in establishing the exploding US market for cocaine in which he claimed that he handled about 85% of the supply in the 1970’s. Although it was a movie that could be presented as a masterpiece for the awareness of the society, the movie missed its attempt. The death of the hero was tragic but his appearance in the movie appealed the young generation to a great extent. â€Å"Blow outlines the lifestyle of a mega-rich smuggler — the border crossings, the ruthless negotiations, the sudden betrayals, the wild characters, the run-ins with the justice system, the inherent problems in dealing with massive amounts of cash, the temptations — and, ultimately, the tragedy of blowing all of your dreams for greed. † 2. Trainspotting This Academy Award nominated movies was produced in 1996. Denny boyle directed it. This movie was based on a novel â€Å"Trainspotting† by Irvine Welsh. The screenplay was adapted from Welsh’s novel by John Hodge. This movie begins with the narration by Renton, who is a rent boy, he tell others that they should choose to live traditional family life. After his narration he tells that his train of thoughts ends with â€Å"who needs reason when you’ve got heroin? † all of his friend were addicted to drugs. The movie rotates all about dirty drugs business and its dealings. The movies most critical part is when Renton leaves drug addiction he feels no purpose of life. He then also deals in selling the heroin. Later Renton realizes that his friends are no his friends at all and leave them for a better life. â€Å"Its release sparked controversy in some countries, including the United Kingdom, Australia and the United States, as to whether it promoted drug use or not. U. S. Senator, Bob Dole, decried its moral depravity and glorification of drug use during the 1996 U. S. presidential campaign, although he admitted that he had not actually seen the film. † 3. The basket ball diaries This movie was produced in 1995 and was directed by Scott Kalvert. It was written by Brian Goluboff. The movie is an autobiographical account of poet and rock musician Jim Carroll. The running time of movie was 105 minutes. As a member of an outwardly invincible high school basketball squad, Jim’s life centers around the basketball court and the court becomes an allegory for the world in his mind. It was biggest dream of Jim to become Star of basketball. He was Catholic high school student but later become drug addict due to bad company. Jim and his friends roam the streets of New York City as trivial thieves and revolts. Soon school expelled the Jim for he took drugs before game. Later Jim faces more trouble when his family throws him. This movie is a critical for most of its scene describing, â€Å"A youth (a mere school boy of age 13) is enjoying the drugs† and hence portrayed that it is not very offensive of a young boy or girl to take drugs in that age specially. â€Å"This movie contained incredibly dark and vulgar guided imagery which could quite possibly lead the impressionable into moral and value modification, poor coping skills, and dangerous decision-making. † 4. Fear and Loathing in Las Vegas The movie Fear and Loating in Las Vegas was released on May 22, 1998. It was directed by Terry Gilliam. This film was based on Hunter S. Thompson’s 1971 novel Fear and Loathing In Las Vegas: A Savage Journey to the Heart of the American Dream. Journalist Raoul Duke and attorney Dr. Gonzo travel from Los Angeles, California to Las Vegas, Nevada in 1971 to cover a motorcycle race for a sports magazine and enjoy a haphazardly planned vacation. Fueled by the massive amount of drugs they purchased with an advance from a magazine to cover a sporting event in Vegas; they set out in the Red Shark. Wreak havoc upon the citizens of Las Vegas. Encountering police, reporters, gamblers, racers, and hitchhikers; they search for some indefinable thing know only as the â€Å"American Dream† and find fear, loathing and hilarious adventures into the dementia of the modern American West. The movie is filled with violence and drugs series. It effected the audience to en extent that even an incident got attached to it. During shooting Gilliam was approached by a group of young men, one of which complimented him on the film in general, but said that his favorite scene was the andrenichrome scene. He said that he had used the drug and that Gilliam had captured the effects perfectly. Gilliam didn’t have the heart to tell the kid that it was made up, and went along with his story. 5. Dazed and confused Dazed and confused is a 1993 American film written and directed by Richard Linklater. The movie tells the stories of the last day of school in May 1976 in a Texas suburb. As the movie begins, the last day of school at a high school is beginning. The last day at Robert E. Lee High School proceeds with regular classes but the soon-to-be-senior class (Class of 1977) is more interested in getting ready for the annual hazing of the incoming freshman class, which will take place after school. The hazing is depicted as a ritualized event that has the support of the town, in the movie. Randall Pink Floyd was a football player who moves with simplistic grace among groups of greasers, nerds, stoners, and athletes alike. The coaches introduced a new policy for the upcoming 1976-77 school year in which athletes have to sign a written pledge that they will not use alcohol or illegal drugs. Pink refuses to sign the pledge sheet. The coach berates Randall Floyd for hanging out with â€Å"that other crowd† (referring to his stoner friends) and Floyd takes offense to it. â€Å"The movie conspicuously shows the much more relaxed attitudes toward both teenage alcohol consumption and driving with open beer containers at the time; Kramer can easily buy beer as the lawful Texas drinking age at the time was 18 and even that was lightly enforced. † References 1. http://www. thc-ministry. net/history-of-drugs. html 2. http://www. getsomeblow. com/index2. html 3. http://parentingteens. about. com/cs/drugsofabuse/a/druguse10_2. htm 4. http://en. wikipedia. org/wiki/Trainspotting_(film) 5.
