Symptoms And Symptoms Of Schizophrenia - 1733 Words

Schizophrenia One may have heard of schizophrenia, but they might not understand what it is. Schizophrenia is â€Å"one of the most serious [psychological disorders that] involves severely distorted beliefs, perceptions, and thought processes† (Hockenbury 564). People who suffer from schizophrenia do not have a good grip on reality. Unfortunately, â€Å"they become engulfed in an entirely different inner world, one that is often characterized by mental chaos, disorientation, and frustration† (Hockenbury 564). People who have schizophrenia can develop positive or negative symptoms. Positive symptoms are defined as: â€Å"extra feelings or behaviors that are usually not present†(cite). Examples of positive symptoms include: â€Å"believing that what other people are saying is not true (delusions), hearing, seeing, tasting, feeling, or smelling things that others do not experience (hallucinations), or disorganized speech and behavior.† (I moved this so that it flowed a little better instead of jumping between positive and negative). On the other hand, negative symptoms are defined as: â€Å"lack of behaviors or feelings that usually are present† (cite). Negative symptoms include â€Å"losing interest in everyday activities, feeling out of touch with other people, family, or friends, lack of feeling or emotion, having little emotion or inappropriate feelings in certain situations, and having less ability to experience pleasure† (What 1).

Genetic Engineering Escherichia Coli - 1789 Words

Genetic engineering is the deliberate modification of the characteristics of an organism by manipulating its deoxyribonucleic acid (DNA). Bacteria possess plasmids which can be used as vectors for bacterial transformation. The plasmids can be altered to include donor DNA thus altering the physiological or physical characteristics of the bacterium. Escherichia coli have been found to be the most effective bacterium in genetic transformation and heterologous expression of human genes or proteins. It was hypothesised that Escherichia coli HB101 K12 could be transformed with a pGLO plasmid to express the genes encoded for green fluorescent protein (GFP), the bla gene for ampicillin resistance and the araC gene a regulatory protein in facilitating transcription and therefore the transformation efficiency for this bacteria could be calculated. Bacillus megaterium, E.coli B strain, Erwinia carotovora, Pseudomonas fluorescens, Staphylococcus epidermidis and Streptococcus lactis will also be subjected to transformation with the pGLO plasmid to collect transformation efficiency data for comparison against Escherichia coli HB101 K12. Escherichia coli HB101 K12 were found to have been successfully transformed with a transformation efficiency falling within the transformation protocol of 8.0 x 102 and 7.0 x 103. The incidence of Escherichia coli HB101 K12 on the LB/amp and LB/amp/ara pGLO+ plates indicated that the bacterial colonies present showed resistance to the ampicillinShow MoreRelatedBearing Light On Gene Expression : Streamlining Light Controllable Escherichia Coli1041 Words   |  5 PagesBearing Light on Gene Expression: Streamlining Light Controllable Escherichia coli Two-Component Transduction Systems Antonio Torres November 16, 2014 Advanced Biochemistry and Molecular Biology CHEM 4360/5383 Abstract Optogenetics is a rapidly evolving technology that, using a combination of optical methods and genetics, is capable of producing high resolution information on specific events of interest within biological systems, whether they be freely moving organisms or not (Diesseroth, 2011)Read MoreLara Guvelioglu.

National Airspace System Free Essays

MGMT 203 Management for Aeronautical Science Manager’s Perspective Paper – The National Airspace System (NAS) March 16, 2013 Prepared for Dr. Daniel Nation Lecturer Prepared by Ong Wei Jian Lionel Introduction In this report, we will be looking at the National Airspace System (NAS). We will be taking an in depth look at the overview and the infrastructure of the NAS, discuss about the FAA Next Generation Air Transportation System (NextGen), and also examine the future needs of the National Airspace System. We will write a custom essay sample on National Airspace System or any similar topic only for you Order Now Overview of the NAS The National Airspace System is defined as a complex combination of systems, procedures, facilities, aircraft, and personnel which work together as one system to ensure safe and efficient air travel in the United States. The NAS consists of several components, and these include: †¢ NAS Operational Facilities (unstaffed) †¢ Air Route Traffic Control Centers (ARTCC) †¢ Air Traffic Control Towers (ATCT) †¢ Ground Radios and Radar Systems †¢ Airports †¢ Aircrafts (commercial, private, and military) Airline Personnel (operating, maintaining, and modernizing the system) †¢ Passengers (commercial and military) Infrastructure of the NAS The NAS helps to maintain a safe and efficient flight over the US airspace by allowing all control towers, control centers, radios, radars, and many airports to be interconnected to one another to form a NAS operational communications network. This NAS communications network helps pilots to communicate wi th air traffic controllers and airline operation centers to ensure a safe flight as they travel over the airspace. There are a three systems that make up the NAS, and these include the Digital Airport Surveillance Radar (DASR) System, the Voice Communication Switching System (VCSS), and the Department of Defense (DoD) Advanced Automation System, or DAAS for short. The DASR System is a traffic air control radar system that helps to detect aircraft position and weather conditions in the vicinity of civilian and military airfields. It consists of two main electronic subsystems: the primary surveillance radar and the secondary surveillance radar, which make use of electromagnetic waves reflected off aircraft to monitor their positions. The VCSS is the communications system used to manage the voice communications of any Air Traffic Control (ATC) facility. The VCSS must be able to support all analog and digital communications between the DoD, the ATC facilities, and the pilots. The DAAS is a system that is used to retrieve and process radar data, flight plans, and weather / airport environmental data to support DoD ATC services. The system transmits part or all of this processed data to a display or workstation (within geographical proximity) for air traffic controllers to access in order for them to control and monitor the activities in the airspace. FAA NextGen Air Transportation System The NextGen program is an initiative developed by the Federal Aviation Administration (FAA) to help improve the efficiency, convenience and dependability of the NAS. The NextGen modernization of the U. S. air traffic system seeks to increase the efficiency of the NAS through technological advancements; and as well as improved approaches and procedures. The NextGen program plans to make use of satellite navigation, which will allow pilots to know the precise locations of other airplanes around them and enhance the overall safety of air travel. Airports are now already benefitting from the NextGen program. These new capabilities include the national rollout of a network of Automatic Dependent Surveillance-Broadcast (ADS-B) ground transceivers. These transceivers will receive GPS position reports from aircraft equipped with ADS-B Out (an upgrade required by 2020 for aircraft flying in most controlled airspace); and by 2013, these transceivers will be installed to provide nationwide coverage. Air traffic data such as Traffic Information Service-Broadcast (TIS-B) and Flight Information Service-Broadcast (FIS-B) will be transmitted by the ADS-B transceivers. The FAA also tested a newly automated Collaborative Departure Queue Management (CDQM) system that aims to help airports improve departure management. The FAA is also putting in place tools that will enable airport operators, airlines, and other NAS users better access to shared surface surveillance data, which is vital for safe and efficient airport operations. The Future Needs of the NAS The current features of the NAS unfortunately, are not sufficient to guarantee efficient or uninterrupted operation in the future. The greater interconnectivity of systems brought about by the NextGen program means that the cyber risks to the NAS are also increased. The future cyber security needs of the NAS require a change in both the NAS infrastructure and safety culture in order to be effective against increased the potential cyber risks that will follow. Improved cyber security requires changes to the present NAS safety provisions. More safety reviews for continual monitoring is needed. Actions and responsibilities of each and every NAS staff now have to be carefully scrutinized and taken into consideration. Responsibilities of system administrators and network operators have to be expanded, from maintaining the performance of the system to detecting intrusive actions. Improved cyber security also requires changes to the current NAS infrastructure. Data provided by external partners and actions requested by external partners have to be made sure that they are not malicious in intent. The existing cyber security architecture also has to be modified and upgraded accordingly to counteract the changing cyber threats, all in a short timeframe; whilst not compromising on the operations of the NAS during these infrastructure changes and modifications.
