Process Architectural Design - Essay Example The essay discusses that the fire and security monitoring system is meant to manage, and to monitor the fire security alarms in a building. In order to best understand how this system works, it is only prudent to define its design both in terms of the software and the hardware components that it is made up of; we have to know how the systems components relate to each other and functions of every component involved in the working of the whole system that is controlled from the central point of security monitoring. When designing the system, we assumed that the system acts in real time and does not respond on false alarms. A large building requires an automated alarm system to monitor and control all fire and security alarms within the building. The building is sub-divided into zones, and a given number of alarms are associated with each zone. Alert for a central manned control area is provided by the alarm. This centre may may respond personally or pass these on to the emergency servi ces. Automated alarm system helps recognizing the risk and allows quick response. Fire and security alarm systems are often active to ensure that whenever there is a fire, the presence of the fire is immediately established and reported through the interactions of the software and hardware components of the whole system. The software components of the system work to manage the various different hardware components, which are associated with the alarm, which is installed to notify the necessary authorities to go to the attention of the fire and put it off. In modern equipped facilities, and in modern buildings, fire alarm and security systems are always associated with the whole security systems of the buildings. These systems work in tandem with them most of the time (Robinson 2009). This interaction is necessary to ensure that catastrophes do not happen; or in any case, they do happen, they can be attended to in due time. When a fire starts in such a building, one of the hardware c omponents detects it through one way or another as will be discussed later on in this document. The component coordinates with another component in the system to notify or to activate something or an action of the surveillance system and even the security system. In a typical fire and security alarm system, components are installed in such a way that they are according to the specifications of the devices and make it easy to access them when the need arises (Robinson 2009). The hardware components that have to be in a fire alarm and security system include: 1. The control system – this is the central component of the entire fire alarm system. It is known as the fire alarm central. This component allows for the precise programming of the manner in which the other individual components behave, hence the behavior of the entire system can also be programmed. This makes sure that notification come in at the precise time and accurately as possible in case of an event. The fire alar m central has points of input; with which it receives signals from the devices that initiate notifications, as well as points of exit; that it uses to activate alarm systems. 2. The initiating and the alarm devices – the initiating devices can be automatic as smoke/fire detectors or can alternatively be manually actuated to notify the central. 3. The power supply and the cabling – it is critical to have a very reliable power supply for a fire and security system so that it remains on at all times. Power back up systems must be installed just in case the main power systems fail. The signal cables are the ones that make the connection and links between each and

Desorption Ionization Methods Essay

Desorption Ionization Methods Essay Pharmaceutical science Desorption ionization methods owning a powerful capability in pharmaceutical field in which the ionization sources provided by the respective mass spectrometers was able to minimize the damage causing any variations in molecular structures of the samples (Monagas, Quintanilla-Là ³pez, Gà ³mez-Cordovà ©s, Bartolomà ©, Lebrà ³n-Aguilar, 2010). The prevention can be done by using ideal matrix mixed with the analytes, owning properties of strong absorption, good mixing and having low vapor pressure. With these properties the mass spectrometer are able more accurate in determine the intact molecular m/z value of the analytes. MALDI-TOF MS Huge numbers of researchers was reported a species that associate with various benefits in health known as proanthocyanidins , a polyphenols compounds which having properties of cardiovascular and neurodegenerative diseases prevention (Aron Kennedy, 2008). Several authors were characterized proanthocynidins in both plants and non-plants foods by the application of MALDI-TOF MS in term different mode of detection and mass species. Two different mode of detection, reflectron mode and linear mode, have been well applied in proanthocynidins analysis. By using MALDI-TOF MS applying on proanthocynidins analysis owning a great advantages in minimize the difficulty in interpret the spectra in which it used single-charged molecular ions for detection that can eliminate those impurities peak that generate by other sources (Monagas, Quintanilla-Là ³pez, Gà ³mez-Cordovà ©s, Bartolomà ©, Lebrà ³n-Aguilar, 2010). The proanthocynidins are essential in food plants and non-food plants sample. This review was provides three example for both plants that are available in journal article. For the food plants, apple juice procyanidins was detected by MALDI-TOF MS in linear mode by both [M+Na]+ and [M+K]+ had been well studies by Shoji, et al. (2006). The authors were concluded that the apple juice procyanidins was exit as B-type procyanidins and the observed mass of the species reported as [M+K]+ are higher than [M+Na]+. Other foods plant, Grape seeds, was reported by Krueger, et al. (2000) as [M+Na]+ in both reflectron and linear mode. The type of proanthocyanidin was being detected are B-type procyanidins and galloylated (esterified form) in various range of degree of polymerization (DP). It was found that the linear mode can be detected up to DP 11 while reflectron mode only can detect up to DP 9. Besides, Krueger, et al. in 2003 was reported another foods plant, Sorghum (Sorghum bicolor (L.) Moen ch), as [M+Cs]+ in the reflectron mode was able to detect A- and B-type procyanidins and prodelphinidins. Due to the complexity of this food plant, the authors enable the detection up to DP9 containing up to 5 A-type linkages and confirming the abundance of the linkages in Sorghum (Krueger, Vestling, Reed, 2003). On the other hand, non-food plants proanthocynidins can also applied by MALDI-TOF MS. However, in the application of non-food plants, unlike application in food plants, Hedqvist, et al. (2000) was reported the Lotus corniculatus (var. Fargus) have presented B-type procyanidins and prodelphinidins by the application in both reflectron and linear mode were detected as [M+Na]+. By establishing reflectron mode, B-type procynanidins and prodelphinidins in acetylated form in bark of Pinus radiata were reported by Ku and Mun (2007). Besides, profisetinidins and prorobinetinidins in heartwood of Quebracho (Schinopsis balansae) were reported by Vivas, et al. (2004).

(2004) FAB-MS The application of FAB-MS in pharmaceuticals sector was baring an importance role in analyzing those nonvolatile compounds in yields abundant ions and detailed fragmentation data (Bartner, et al., 1997). Everninomicin-6 (EV-6) was reported as an oligosaccharide antibiotic by Bartner, et al. (1997). The authors were using previous studies, Everninomicin-D (EV-D), by comparing their fragmentation m/z value in order to well analyze the fragmentation. Besides, the paper also operated by using various types of matrices in order to illustrated more structurally informative fragment ions such as glycerol, thioglycerol, glycerol/thioglycerol, 3-nitro-benzyl alcohol (3NBA), and 3NBA+NaCl. In the studies, the FAB spectra were yields a very weak protonated and a relatively low-abundance sodiated molecular ions at m/z 1335 and 1357 respectively. The authors were emphasize that the matrix, NaCl doped 3NBA was producing the best result among the matrices that they were used. The spectra were able to shown a clearer enhancement of the sodiated molecular ion at m/z 1357 and the authors also able to determine several series of the molecular fragmentation. This make the spectra more essential in define the structurally informative ion constituent. However, negative-ion FAB-MS had been investigated by the authors for the structural analysis perform by using DMSO-3NBA matrix and produced abundant molecular ion at m/z 1333 and a series of cleavage of ions peak. Table 2: The relatively abundance molecular ions peak of the Everninomicin-6 (EV-6) in DMSO solvent Matrices Mass specie Observed mass Assignation 50:50 glycerol/thioglycerol (gly/thio) [M+H]+ 1335 1357 -very weak protonated molecules ion -low-abundance sodiated molecular ion 3NBA + NaCl [M+Na]+ 1357 -abundant sodiated molecular ion 3NBA [M-H] 1333 -abundant molecular fragment ion SIMS Applications of SIMS in pharmaceutical sector are used to detect the surface morphologies of the analyte. In order further improve the detection limit, Chen, et al. (2011) research was using C60 cluster ion sources. The studies were done by the event-by-event bombardment/detection mode and providing benefits which allowed the detector very narrow length (~10nm) molecules. Chen, et al. (2011) were reported that this mode was increased the sensitivity of the detection toward the closer distances between nanoparticle probe and amino acid sites of an antibody. It was reported that the gold nanoparticles (AuNPs) was modified in which the antiCD4 cooperate to the AuNPs and immobilized on the cell for analyze. It was reported that the negative ions that cleavage by the molecules in the range of m/z 30 to 120 were indicating the present of the antibodies on the cell. Besides, m/z 197 and m/z 223 corresponding to Au and AuCN respectively, were shown the importance of the peak which indicating the immobilization was successful. On the other hand, the ions source of C60 caused the impact on the lipid membrane region where the fragmentation palmitate (C16H31O2) and oletate (C18H33O2) at m/z 255 and 283 respectively had occurred.

Operation Bluestar Essay

The topic of â€Å"Operation Bluestar† is a very controversial issue because of where the Operation took place and all the events that occured. Operation Bluestar, was the code name given by the Indian government. It was an operation to evict Sant Jarnail Singh Bhindranwale and his followers from the Golden Temple. The Golden Temple is one of the most sacred places of worship for the Sikh community. It is also one of the oldest Sikh temples around. The Golden Temple is known has the Harmandir Sahib, and is located in the city of Amritsar. Many questions arise to why something like this would happen in the first place. Bhindranwale was a Sikh fundamentalist. He was a leader of the Damdami Taksaal. The Damdami Taksaal is a Sikh religious intuition and it was founded by the tenth Sikh Guru. Bhindranwale directed the campaign of terrorism in Punjab. He was associated with the movement of an independent Sikh state. The state would have been known has â€Å"Khalistan†, but there was very little support of it in Punjab by Sikhs. Bhindranwale had been a problem for a couple of years before Operation Bluestar. He and his followers had been murdering and intimidating moderate Sikhs and Hindus. They increased the pressure on Indira Gandhi to do something about it. By this point Bhindranwale and his close followers transformed the Akal Takht, his headquarters within the Golden Temple. He had changed it to an armory and a sanctuary for terrorists, and from here he conducted his campaign. This is when Operation Bluestar comes into play. Indra Gandhi has initiated the attack on May 31, 1984 on the Golden Temple. The Golden Temple is located in the city of Amritsar and it is a sacred place of worship for the Sikh religion. Gandhi waited six months before finally ordering the army to get Bhindranwale and his followers out. Many say that Ghandi waited six month in order to build a positive public opinion about it, because it would have sparked a lot more negativity than it already did. Five days before the army entered the Golden Temple, 48 people were killed. The only way now that Gandhi could get Bhindranwale out was to use force, so she sent in the army in to the Golden Temple. The army was not prepared, because there were a lot more extremists than expected, they were also armed far better than intelligence reported. The extremists had responded to the army’s first initial call for surrender with machine guns. The operation turned into a bloody 3-day siege. 576 people were killed, 83 of them being soldiers from official count, but unofficial counts suggest that estimate to be as high as 1,000. The Operation left many scars, approximately 1,000 army members were involved and a casualty rate of one-third of four officers. Bhindranwale was found dead in the basement of the Akal Takht, along with the leader of the Sikh Student Federation, and a sacked major general of Indian Army who had reportedly trained Sikh terrorists. Gandhi had also sent the Indian army into Punjab on June 2nd, 1984, to surround thirty-eight Sikh temples that had believed to been harboring Sikh militants under the command of Bhindranwale. Throughout the sate of Punjab, Akali leaders were placed under arrest. The generals in charge of Operation Bluestar consisted of 4 Sikhs and 2 of another cast. Their involvement did little to reduce the sense of humiliation and the anger among nearly all the Sikhs. The Golden Temple also suffered damage, the Temple is also known as the Harmandir Sahib. Both the terrorists and the army had destroyed it. The terrorists used it for gun placements and army had attacked it. The Akhal Takht suffered the most serious damage and the precious Golden Temple Library was set on fire. Almost all Sikhs were outraged by all the destruction that was caused to the Temple. The main question that everyone has is why did Bhindranwale choose to hide in the Golden Temple with his militants and weapons, when he could have went anywhere else. It is because he thought he would be safe their. He never thought that the Indian Government would attack him their because it is a sacred place of worship for all Sikhs. Also a government cannot allow armed militants to enter and attack a holy place. Bhindranwale thought of it in both ways, if they attack he would have an advantage as well. By having the government attacking a holy place many people would be outraged such as the Sikhs, the Sikhs and other people would then be against the Indian Government because of what they did. That is exactly what happened, the government attacked and that sparked the anger between all Sikhs, no matter what they thought of Bhindranwale and his battle for â€Å"independence† that he wanted. By hiding in the Golden Temple and having the army attack, it really helped Bhindranwa le get his message out to the people. The attacks made the news world wide, and he became famous and people started to know what he was fighting for. Another reason of him hiding there was that many civilians were in the Golden Temple and that made him believe that the Indian Government would not attack, because that would kill innocent people. But the Indian Government did just that. The government, while being successful in killing Bhindranwale, took the lives of many innocent men, women, and y children. Bhindranwale, while knowing that many civilians would be in the area that could be harassed and killed, he still chose to stay their. That might have been intentionally done, or he might not have known that. But it ended up being deadly for the civilians. Bhindranwale’s actions caused a lot of damage to the Golden Temple, by converting into a battlefield with a lot of bloodshed of innocent people. But this was all done because of his cause of creating Khalistan. Many may inquire why the Indian Government finally decided to attack the Golden Temple a holy place of worship, after a six-month period of not doing anything. Many people believe that the Indian Government did wrong by attacking the Golden Temple, but you have to analyze both sides before coming to a proper conclusion. The Government was wrong at attacking at a holy place but they had to because Bhindranwale would not surrender himself. The army had asked him to surrender, however Bhindranwale refused to and in turn he started firing back at the army. The Army had no choice, so they fired back and this is how the innocent victims were killed along wit the Golden Temple being destroyed by all the gunfire. The Indian Government were not the only ones to destroy it, although many may think that Bhindranwale had his own machine guns at the temple and he was also a big contributor to the destruction of it. Had he had surrendered then, the many people that were killed would not have been and the Golden Temple would not have been damaged in any way. The Sikhs would also have not been angered. One thin that makes the Indian Government seem really bad is the fact that they decided to attack the Golden Temple in the same week as the Sikh religious day known as the martyrdom of Guru Arjan Dev. Guru Arjan dev was the one who completed the Golden Temple. It was founded by the fourth Guru of the Sikhs, Guru Ramdas. The Indian Government knew that thousands of Sikhs would gather. This is one of the reasons of such a high casualties rate of Sikhs. A direct connection of it being the Indian army’s fault cannot be made because both Bhindranwale and Indian Government made mistakes. One side cannot be blamed for it all. The people affected by the whole Bluestar Operation were the many of the Sikhs and Hindus as well. Many Sikhs and Hindus died because of the Operation taking place. The Sikhs died directly because it and the Hindus died because the Sikhs were angered. The Indian Police targeted many Sikhs after the Bluestar Operation, if they seemed to have any ties with Bhindranwale or believed in what he was standing for they would be killed or harassed. Many Sikhs became martyrs and held off the Indian army for as long as they possibly could. A total of about 250 men had kept the army out of the Golden Temple. The army consisted of over 250,000 troops. The army had entered the Temple after six days of the Sikhs stopping them from entering. They started killing innocent Sikhs who came to visit the Temple to celebrate the religious day. When the army came to know that only 250 stopping any army of troops, they were angered and humiliated. The Sikhs in the temple were lined up and shot at point blank range. They ranged from the eldest of people to the adults and the children, no one was spared. What really hurt the Sikhs was that their sacred artifacts and library was burned. Also literature written by the Sikhs Gurus was also not found after the attacks. It has been said that the army had taken it, but they state that it had been destroyed during the attack. The city of Amritsar had been destroyed. Many visitors visiting from other countries around the world had been arrested or killed. Sikh shops were robed and houses had been burned. Hindus also had a role in the killing of the Sikhs. Groups of Hindus went to Sikh households and burned the Sikhs alive. They also raped the Sikh women and violated pregnant women. The Sikhs that were being targeted were young males ranging from 4 to 40 years of age. The Indian Government had feared that the younger Sikh males would rebel and that by killing them would diminish the young Sikh community and the Sikh population would not flourish. They hoped that maybe the Sikh community would disappear and no longer be a problem for them. The main reason why many of the Sikhs were going through this was because Hindus wanted to destroy Sikhism. When Sikhs in other places found out about the attack that occurred in Amritsar, they rebelled. The Sikhs killed many Hindus that were in high rank. The Indian Government then noticed this movement by the Sikhs and quickly acted on it. They began arresting Sikhs and killing them. Over 40,000 Sikhs were in jail with being charged. Before the Bluestar Operation Sikhs and Hindus were killing each other. When a Hindu would kill a Sikh, the police would do nothing about it, but when a Sikh killed a Hindu the Police would arrest and punish them. After all had happened to the Sikhs they still stuck together and rebelled to take over the Golden Temple that was theirs. They were successful in doing so.

Different minerals appear in any given rock depending upon the type of rock and the amount of heat and pressure the rock undergoes. Geologists look at the minerals in rocks to determine how much heat and pressure - and thus how much metamorphosis - the rock has undergone. Certain minerals, called index minerals, only appear in certain rocks at certain pressures, Thus, index minerals can tell geologists how much the rock has metamorphosed. Examples of Index Minerals The most widely used index minerals are,  in ascending order of pressure/temperature,  are biotite,  the zeolites,  chlorite,  prehnite, biotite,  hornblende,  garnet, glaucophane, staurolite,  sillimanite,  and glaucophane.   When these minerals are found in particular types of rocks, they can indicate the minimum amount of pressure and/or temperature the rock has experienced. For example, slate, when it undergoes metamorphosis, changes first to phyllite, then to schist, and finally to gneiss. When slate is seen to contain chlorite, it is understood to have undergone a low grade of metamorphosis. Mudrock, a sedimentary rock, contains quarts at all grades of metamorphosis. Other minerals, however, are added as the rock undergoes different zones of metamorphosis. The minerals are added in the following order: biotite, garnet, staurolite, kyanite, sillimanite. If a piece of mudrock contains garnet but no kyanite, it has probably undergone only a low grade of metamorphosis. If, however, it contains sillimanite, it has undergone extreme metamorphosis.
