Operating system new and old one - Essay Example Indeed, the evolution of OS correlates with the growth in IT and computer needs. Examples of old operation system include Admiral Operating system for Honeywell 800/1800, Atlas I Supervisor that introduced system calls and virtual storage for the first computer. We also have the SCOPE operating systems developed in the 1960s that enabled batch processing and the MACE operating system for sharing time. The Michigan Terminal System (MTS) and MUSIC/SP are also examples of old OS developed for early computers like IBM. However, the complexity of new hardware and application programs led to the development of new OS. Indeed, the old OS lacked important features that are present in new OS such as the capacity to run third-party applications and multiple applications at once. Examples of new OS include Microsoft Windows, Android, IBM z/OS, Mac OS X, iOS, and Linux (Computer Hope 1). Most new OS adopt a touchscreen input design since it applies to portable devices. Notably, Microsoft Windows is the most dominant OS used in PCs, IBM, and smartphones (Computer Hope 1). The Apple Mac OS applies only in Apple computer operating system and on Macintosh computers while Android OS is applicable in all Android compatible phones (Computer Hope 1). Moreover, Linux is a new OS applicable in PC and IBM compatible computers while iOS operates with the Apple iPhone (Computer Hope 1). Notably, the choice of an OS depends on the hardware though all operating systems offer a graphical user interface that entails a des ktop and the capacity to manage files and folders. The early OS embraced diversity where technicians produced multiple OS to apply in a specific mainframe computer. However, the old OS had different command models, operating protocols, and operating tools. The development of new computers and hardware resulted to the introduction of new OS where the technicians adjusted, retested, and restructured the applications to accommodate the new OS. The new OS

The cylindrospermopsin alkaloids Literature review

The cylindrospermopsin alkaloids - Literature review Example CYN is a natural toxin which is usually produced by certain cyanobacteria species majorly Cylindrospermopsin raciborskii and Umezakia natans among others (Masten 2000). The presence of CYN in drinking or recreational water poses a serious environmental and health risk. CYN was initially isolated in 1992 following a suspected outbreak in Palm Island; Australia. Since its isolation and classification, various techniques have been used to isolate, detect, analyze and purify Cylindrospermopsin (Moore, Ohtani and Runnegar 1992). Some of the common techniques include; High Performance Liquid Chromatography coupled with Photodiode Array Detector (HPLC-PDA), Enzyme Linked Immuno-sorbent Assay (ELISA), NMR/Mass Spectrometry (MS), filtration and adsorption techniques among others Masten 2000). This paper shall describe how to grow CYN using bioreactor, analysis using ELISA and HPLC, purification of CYN and analysis using NMR/MS. Detection of Cylindrospermopsin in surface water is important sin ce it acts as the major source of drinking and recreational water for a large percentage of people throughout the world. The Cylindrospermopsins should be constantly removed from water to prevent contamination from toxins which are known to cause hepatotoxicity among other toxic effects (Fastner et al. 2003).Cylindrospermopsin is produced by various cyanobacteria species commonly known as blue-green-algae which are mostly found in fresh water. Some variants of Cylindrospermopsin raciborskii commonly found in U.S., Australia and Hungary, Umezakia natans isolated in Japan and Aphanizomenon ovalisporum found in Israel and Australia produce Cylindrospermopsin (Fastner et al. 2003). Human poisoning which occurs through ingestion of water or food contaminated with Cylindrospermopsin producing strains is the most common problem associated with the toxins. It has been suggested that toxicity by Cylindrospermopsins is majorly mediated through inhibition of protein synthesis which causes loss of liver functioning leading to death of cells. Use of a bioreactor in growing CYN Bioreactors can be used in the growth and isolation of CYN due to their ability to allow controlled growth of the organism under specific conditions. A bioreactor can be used to characterize CYN in terms of its relative biological and chemical components while allowing reproducible generation of the target compound. Bioreactors enable the proliferation of the CYN cells by controlling the environment under which the cells are cultured. Typically, a bioreactor for CYN should alloy control of certain environmental conditions that favor the growth of the organism. Using a bioreactor, conditions like oxygen concentration, temperature, stress and PH as well as sterility are maintained during the procedure (McMahon et al. 2008). The proliferation of CYN cells is also facilitated by the availability of essential nutrients alongside the removal of harmful toxins that can inhibit the growth of the cells. Biore actors enable different operations to be undertaken including fed-batch, batch and continuous cultivation (Choo et al. 2007). Continuous perfusion allows the growth of CYN cells under stable and controlled environmental situations. Isolation of CYN using charcoal filtration method Studies have demonstrated that CYN can be isolated successfully through adsorption techniques utilizing various sediments. Powdered Activated Charcoal (PAC) has been found effective in removing CYN from

One page reflection based on experience - Essay Example ompetition instilled in us an aspect of self-confidence in all we did thus winning every match besides developing additional skills due to practising harder. This is because we aimed at ensuring retaining our position as the leading team during all games we played. Sometimes we lost, but instead of being discouraged, losing to our competitors made us go back to the drawing board to examine and analyse our weak points. By understanding where we went wrong, it became much easier to find the way forward. Competition built teamwork, which uninterruptedly lead to the success of the team. Basketball involves passing of the ball from one player to another whereby without teamwork this will not be effective because there will be aspects of unselfishness. The healthy competition in basketball instilled a winning attitude in us besides discouraging us to be out of our comfort zones. Determination and perseverance enabled us to achieve the victory we badly needed. However, initially it was not that easy on my part to join an already strong team. I had to prove my worth but with persistence not only I made it but turned to be a reliable player. Extending this aggressiveness in life, competition has always encouraged me to set higher goals than that of my competitors. Through the early sport, I learnt to admire my competitors and strive harder to beat them. Not by copying them, but by being more creative and innovative to outdo them. We should therefore embrace competition for the good values it creates in

History Assignment Example | Topics and Well Written Essays - 250 words - 15

History - Assignment Example The book also records the appreciation and appraisals for her contemporaries and colleagues like Izumi Shikibu and Akazome Emon. The tale diary also unfolds a saga of rivalry between Murasaki Shikibu and her contemporary Sei Shonagon. Along with this, the book evolves out to be one of the most enlightening literary pieces as it captures the authoress’ profound vision on life. The rivalry between, Shikibu and Shonagon composes a formative part of the autobiography and is most instrumental in learning about the socio-economic condition of China during that period in general and women of the Chinese society in particular as the book involves a strong feministic approach being the mirror of a woman’s mind. Both Murasaki and Sei were appointed as the teachers to the Empress Akiko and Empress Sadako. They used to impart education to the Empresses how to lure, seduce, attract and achieve Emperor Ichijo. From this fact, it can be easily contended that the status of the women in the contemporary society was that of a subjugated status. Women were educated not for their own sake but for attracting men or their prospective grooms and this was prevalent in all the classes of the society. Shonagon, the greatest rival of Shikibu, is described in her diary as the woman who is very ambitious and her pursuit for ambition is described as quite desperate which indicates that over ambitious attitude in women were not encouraged in the society of that period. Women were required and expected to be extreme feminine, quite and demure. Expressing fort right opinion in the case of the women was not acceptable in the social context and milieu of Shikibu’s time. Under this situation, Shonagon was projected as a woman who devastated every opposition by the force of her sarcasm and that of her wit. On the other hand, Shikibu described herself as a quite lady who was not able to mix properly with the society and for this reason she explained that she was looked down upon

My Values, Beliefs, Clinical Gestalt with Individuals and Systems Essay Example for Free

My Values, Beliefs, Clinical Gestalt with Individuals and Systems Essay Becoming a successful clinician is like a work in progress, a clinician should never consider it completed. There is always room to learn, to grow, and develop while working in the Human Services field. The knowledge that a clinician learns comes not only from education but also from experiences and time working in the field. Overtime, a clinician can expect to look at his or her own beliefs, values, and experiences as well as family, cultural dynamics, and background. The main reason a person continues to learn and obtain knowledge, is because of the array of clients a clinician sees. In the textbook, I had to complete exercises that discussed our values and beliefs and how they will affect and interact with our professional lives. The values that are in my life affect and make me whom I am. Several values that bounce between my professional and personal life and some that do not. There are also some values that I need to improve on which will help me in both my professional and personal lives My most important values and beliefs are: -Be respectful -Be open-minded -Be trustworthy -Always do my best -Have a big heart -Work hard -Enjoy life However, the most important thing is to make my values and beliefs flexible so that I can view the clients and better assist them. This is not always an easy task to do, but because of my experiences and my education, I continue to make progress. A clinician takes the ability to adapt and be flexible with your own personal beliefs and values. My experiences in life have always revolved around helping things, whether it was people or animals. My parents use to tell me, and showed by old family videos that I was the biggest tomboy and helper around our family farm. From a very young age, I was often found helping my parents on the farm rather than playing with Barbie Dolls. I would do all types of work on the farm such as feed animal, clean the barn, and milk the cows. These items helped either animals or people. Being raised on a dairy farm, encouraged me to work hard. Once I started high school my hard work did not stop at the farm, I got my first job away from working on the dairy farm. I am still employed at the job and once again because of my hard work I have had several promotional experiences within the company. I have always been a hard worker at everything I do and have learned many of my values and beliefs. Another textbook exercise that I completed discussed how my own family and my culture background will affect my ability to respond and connect with clients. I have learned that how I view others and makes me comfortable when working with clients has to do with how and where I was raised. My cultural background can include my education, social behaviors, ideas, and viewpoints. For example, in one of the exercises I was asked how I would feel working with a client who was African American or a client who was gay. All these items are affected by how I was raised, and my cultural background. Society also influences the lives we live and how we view other individuals. Textbook exercises were also completed concerning this. I have learned that society we live in shape, who we are, just like cultural backgrounds, beliefs, and values. Society can be described as the world, and community we live in. One example of society affecting our beliefs is with same sex marriages. This is a very controversial topic of society. For a very long time, society said same sex marriages are not okay, and recently they are becoming accepted. Because society is saying that it is now acceptable, the people in the communities are affected by this and their viewpoints may be altered. While working with clients a clinician needs to keep their cultural backgrounds and society out of their mind. Clinicians will experience working with clients of all types. It is important to remember that each client seen is different even if diagnoses, traits, characteristics, or anything else is similar. No two cases are alike. Clinicians will work with individuals with physical, mental, psychological, emotional, and verbal, and many other types of individuals. My job as a clinician is important. I need to remember that everything that shapes whom I am is important but private and should not be â€Å"worn on my sleeve. † Everything I do in life affects how I am shaped and how I view others. My values, beliefs, experiences, and the society also affect me. Keeping an open mind, and be understanding toward my clients is an important role and I will continue to devolve this in my experiences.
