Heterogeneous Definition (Science)

Heterogeneous Definition (Science) The word heterogeneous is an adjective that means composed of different constituents or dissimilar components. In chemistry, the word is most often applied to a heterogeneous mixture. This is one which has a non-uniform composition. A mixture of sand and water is heterogeneous. Concrete is heterogeneous. In contrast, a homogeneous mixture has a uniform composition. An example is a mixture of sugar dissolved in water. Whether a mixture is heterogeneous or homogeneous is largely dependent on the scale or sample size. For example, if you look at a container of sand, it may appear to have evenly distributed particles (be homogeneous). If you viewed the sand under a microscope, you might find unevenly distributed clumps of different materials (heterogeneous). In materials science, specimens may consist entirely of the same metal, element, or alloy, yet display heterogeneous phases or crystal structure. For example, a piece of iron, while homogeneous in composition, might have regions of martensite and others of ferrite. A sample of the element phosphorus might contain both white and red phosphorus. In the broader sense, any group of dissimilar objects may be described as being heterogeneous. A group of people might be heterogeneous with respect to age, weight, height, etc.

Integration of Focused Assessments and Review of Systems using QCPR at Research Paper

Integration of Focused Assessments and Review of Systems using QCPR at Trauma Hosiptal - Research Paper Example However, some of the organizations such Trauma hospitals have managed to improve their accuracy in recording patients’ records, delivery of accurate results from their diagnosis and backing-up their patients’ records that are used in any future reference on these patients in case any information regarding the patient is required. Therefore, it is advisable for all medical institutions to develop QCPR system within their organizations in order to enhanced patients’ recording process during medication that requires emergencies. II. Aims of the Study Over the years, medical institutions have faced pressure from their respective government and clients on the need towards the better provision of health care facilities and medications. This requires the organizations to adopt measures that would allow them to introduce a computerized system within their working premises for better service provision. Moreover, the introduction of computerized system would help in the re duction of costs and time consumption that has been experienced before (Mahoney 56). Therefore, the aim of this research paper is to identify various importance of the system using QCPR at Trauma Hospitals in enhancing the medication process especially in recording of patients while dealing with cases that requires emergency attentions. III. ... lped during the analysis of data as they were used to compare some of the information gathered during the research period, for accurate information to be produced. One of the documents that were found helpful while conducting this research is the journal article by Mahoney (92) bearing the title Transforming Health Information Management Through Technology. Through this document, it was easy to note how the implementation of computerized system within healthcare centers needs to be achieved, various importance of systems using QCPR within hospitals and some of the cautions that need to be taken care of in the implementation and use of the QCPR system (Mahoney 59). IV. Methodologies Need for the production of accurate information regarding the research study required that appropriate data collection methods were to be used (Mahoney 60). Therefore, after considering various data collection methods, interviews, use of questionnaires, observations and document analysis were used. Through observation, time taken for hospitals that uses QCPR were taken and compared to the one that have not yet developed computerized system within their organizations. Through the use of interviews, various patients and doctors were interviewed to gather information on the QCPR system as compared to the manual system and some of the challenges faced in the use of QCPR. While in dealing with document analysis, different documents used during the research period were analysis based on the information contain in them in order for synthesized information to be derived.

Juvenile Rights - Essay Example orance is no excuse for a crime, ‎hence no matter what your age is or you were too young for a crime, even a juvenile can be ‎arrested and jailed for crimes. However there are many rules concerning this and many ‎authoritative cases suggesting how people under the age of ten are by no means allowed to be ‎jailed but in fact they can get other services such as community service as a punish. ‎ When arrested, a juvenile becomes either a status offender or has the responsibility for ‎some sort of wrongful conduct. Statuses offenses are when a juvenile commits some crime that ‎would not have been a crime if committed by an adult, such as curfew violation and runaway. ‎Alternatively, wrongful conduct can include offenses that violate penal laws other than some sort ‎of traffic violation. However, if you are under the age of 18 and somehow get in trouble with the ‎law, your case will be heard in the juvenile justice system.‎ Going back on the topic of discussion, we need to discuss what the rights of a juvenile ‎are. A minor commits a crime, but the law is still there and there are rights available for the minor. ‎Firstly there are rights available at the time of arrest.

Terrorism - Essay Example Since its inception, the nuclear bomb has been one of the major threats hanging over the humanity. With the rapid escalation of terrorist movements, the threat of nuclear attacks is becoming even more probable. Despite the growing availability of nuclear materials, the risks of actual nuclear attacks are still minor, simply because nuclear terrorism is extremely difficult to accomplish (Ferguson & Potter, n.d.). The easiest are those acts which result in the least damaging consequences (Ferguson & Potter, n.d.). The problem with nuclear terrorism is not in the availability and accessibility of nuclear materials: in today’s globalized world, getting nuclear materials for a radioactive bomb is not difficult. The main problem is in that creating such a device requires sophisticated technical skills (Ferguson & Potter, n.d.). Building and launching an improvised nuclear device is much more difficult than creating and using a radiological dispersal device (Ferguson & Potter, n.d.). These difficulties, however, do not mean that the probability of nuclear terrorism is zero. As of today, nuclear bombs are the high end of plausibility of what terrorist groups could accomplish (Farber, 2010). The growing insecurity of nuclear materials makes the risks of nuclear attacks even higher. The lack of a comprehensive nuclear terrorism strategy in the U.S. further complicates the situation (Ferguson & Potter, n.d.). Yet, a small group of people who have never dealt with nuclear weapons could easily make a crude nuclear explosive device, with minimum attention drawn to their acts (Harvard Kennedy School, 2012). All these conditions make it easier for terrorist groups to realize their intentions and motives. There are strong indicators that a number of terrorist groups are interested in acquiring and using nuclear power in their acts against civilians. In 1998, Osama bin Laden said that acquiring and using weapons of mass destruction would provide reliable defense of Muslim s against the rest of the world (Harvard Kennedy School, 2012). As of today, at least three terrorist organizations could be planning a nuclear attack: Al-Qaeda, Aum Shinrikyo, and North Caucasus-based separatists (Harvard Kennedy School, 2012). These are the organizations that have demonstrated strong interest in the development of nuclear-based terrorist strategies. The exact number of terrorist groups looking for a nuclear weapon is currently unknown, but Aum Shinrikyo and Al Qaeda have already tried to purchase nuclear materials in the black market (Harvard Kennedy School, 2012). For the past ten years, Al-Qaeda has persistently tried to acquire nuclear materials and continues to pursue the goal of getting a nuclear capability (Harvard Kennedy School, 2012). There are no known cases of acquiring nuclear materials by terrorist groups. Also, it is not clear whether any terrorist groups have access to governments that can obtain these materials for them (Harvard Kennedy School, 201 2). Yet, there are several ways in which nuclear materials needed for the bomb could be acquired: (a) from a global stockpile of nuclear weapons; (2) from international nuclear facilities containing separated plutonium; (3) from states that are claimed to possess nuclear weapons, such as Russia and North Korea; and (4) from training and research reactors (Harvard Kennedy

Assignment Example Most members of the staff understand the linkage that exists between receiving knowledge in their different institutions and learning or working with collogues. However, areas where staffs’ attentions are seriously required are the same areas where students do not place much emphasis, since they work collectively to contribute to the general success of the institutions. However, most students have taken learning as an add-on to their educational career and in most cases do not work collectively as they busy competing against each other for their academic success. It is proven that the learning process can not be a success without certain factors being considered by professionals. In a professional learning community, society members must be in attendance. Both students and staff must gather and come at an amicable solution on the curriculum, instructional strategies, data, goals and the type of learning required to make the process a success. The professionals also are require d are required to direct their attention to the needs of the students involved so as to provide a common purposes for all the students in the school. Professional learning communities also require effective leadership to oversee the whole process. Capable hands of professionals are tasked with major roles of defining purposes for both staff and students in different schools and organizations. This promotes success as the students and staffs are provided with the needed support which is essential to the learning process and success of students. School heads are also tasked with the responsibility of identifying and setting a space for the professional learning community or faculty involved in the process. This allows members of the staff to gain insight from fellow staff members as there is sharing of teaching practices and artifacts needed in student learning. According to Gamble (2008), a professional learning community transforms professional development of both the teachers and a dministrators into goals. It provides a system which enables both parties to fully benefit from it as it advocates for theories and practices which are accordance with the learning and work environment. The community is data driven as both the teaching and administrating professionals are self motivated by the need to meet the different educational and work requirement for the students or employees. It also greatly depends on both parties accepting their responsibilities in accordance with the work structure existing within a society. Professional learning community incorporates the attitude of professional development amongst educators in schools. It provides both parties concerned with a goal that they work to attain. In addition, professional learning community offers teachers with all the relevant resources they need to become successfully in their teaching process to the students. They are motivated to become better and efficient at their work and this result positively as grad es and performance of the students in school and after school improves significantly. Teachers are provided with an opportunity of what to access for the students’ ideas, how to access and ways to conveying it to the students. Professional learning community also provides teachers with the trustworthiness needed in the current data-driven curriculum as they have their objectives and goals organized before presenting it to the
