Solidification Definition and Examples

Solidification, also known as freezing, is a phase change of matter that results in the production of a solid. Generally, this occurs when the temperature of a liquid is lowered below its freezing point. Although the freezing point and melting point of most materials are the same temperature, this is not the case for all substances, so freezing point and melting point are not necessarily interchangeable terms. For example, agar (a chemical used in food and the laboratory)  melts at 85 C (185 F) yet solidifies from 31 C to 40 C (89.6 F to 104 F). Solidification is nearly always an exothermic process, meaning heat is released when a liquid changes into a solid. The only known exception to this rule is the solidification of low-temperature helium. Energy (heat) must be added to helium-3 and helium-4 for freezing to take place. Solidification and Supercooling Under certain conditions, a liquid may be cooled below its freezing point, yet not transition into a solid. This is known as supercooling  and it happens because most liquids crystallize to freeze. Supercooling may be readily observed by carefully freezing water. The phenomenon can occur when there is a lack of good nucleation sites from which solidification can proceed. Nucleation is when molecules from organized clusters. Once nucleation occurs, crystallization progresses until solidification happens. Solidification Examples Several examples of solidification may be found in everyday life, including: Freezing of water to form ice in an ice cube trayFormation of snowCongealing of bacon grease as it coolsSolidification of melted candle waxLava hardening into solid rock

Project Integration Management Simulation Analysis

Project Integration Management Simulation Analysis In the current business environment, the demand for project managers is ever growing. In short, project management is a provisional project constrained by time, cost and scope (A guide to the project management body of knowledge, 2013). Between the immense organization, optimization, and communication assets skilled project management brings to a project, it is easy to see why project management is a booming field of study. Furthermore, project management can be both financially and personally rewarding when long term milestones and goals come to fruition. However, obtaining the knowledge required to successfully orchestrate and manage projects is a challenge within itself. Individuals with the drive and desire to become project managers have a number of options regarding the means of properly equipping oneself for real world project management situations. In addition to seeking an academic degree in project management, and before becoming a certified Project Management Professional (PMP) with the Project Management Institute (PMI), learners are encouraged to participate in Project Integration Management Simulations through the PMI Registered Education Provider (REP) and world-class education simulation company, Double Masters (Double Masters, 2016).

The Effects of Colonization in Africa Free Essays

While Africans were deprived of basic human rights in some regions and lost many of their cultural aspects, these characteristics were overridden by industrialization, more job opportunities, and improved political structure during the European colonization of Africa from late 19th to mid-20th century. In document 5, it states â€Å"when the whites came to our country, we had the land and they had the Bible; now we have the Bible and they have the land,† an African proverb regarding the Europeans. Through missionaries, Africans gained the trade network and interracial relations, and Europeans expanded their territories as a result. We will write a custom essay sample on The Effects of Colonization in Africa or any similar topic only for you Order Now The cheap labor force and raw materials were sent back to the mainland to be finished. The surplus goods from Europe were then sold in higher prices to Africans who could afford it (doc. 2). However, the natives were not always guaranteed equality (doc. 8), thus creating tension. Furthermore, there was friction among different tribes within a colony, due to the fact they were in the same location (doc. 11). Yet, it had a positive impact on economics as well. In some parts of Africa, one woman stated that the people were fortunate to be treated well compared to other parts. They were rewarded goods for their work, and the word â€Å"slavery† was abolished (doc. 6). The railroad was constructed for transporting the materials. Also, different tribes developed irrigation systems, and learned the use of the domestic animals, manure, and mechanical work (doc. 3). Additionally, people were taught different skills such as mining and blacksmithing. Some argued that this is forced, but it is rationalized that the natives are savages, therefore it was for their own good (doc. 1). In addition to economics, Europe brought political stability. From the Europeans’ perspective, the new government implemented by Europeans guaranteed the protection of people and their possessions (doc. 9). The tug-of-war (doc. 4) between the nations shows how it affected a colony’s political system. Thanks to the railroad, the government can oversee their colonies efficiently (doc. 7) while using militarism when needed (doc. 10), protecting their own colonies. Documents that would be helpful are from the ruling class for better understanding of its influence on the social hierarchy. How to cite The Effects of Colonization in Africa, Papers

Institutional Pharmacy Setting Essay Example For Students

Institutional Pharmacy Setting Essay Institutional Pharmacy Setting 1 Institutional Pharmacy Setting Axia College of University of Phoenix Leonalda Cruz Institutional Pharmacy Setting 2 An institutional pharmacy provides an array of services for residents of nursing homes, hospitals, hospice care, and other long term facilities. In this particular setting, the pharmacist will take responsibility for the medication that the patients’ need and ensures that patients’ medications are appropriate, effective, safe, and they are used correctly. A pharmacy technician may work with less supervision in this setting, so it is important that the technician also be familiar with dosing, compounding, IV administration, and other drug relation procedures. The institutional pharmacy provides delivery service and prescription drugs that are individually packaged. Pharmacists constantly check patients’ drug interaction to avoid duplication of the treatment and reactions. The institutional pharmacy is a principal defense against medical errors and allows the pharmacists and staff to provide patient the quality care that they deserve. The pharmacist counsels patients, provide drug regimens, and oversee medication distribution. Institutional pharmacists and technicians use controlled dispensing systems to make sure that patients have the right drugs at the right time and in the proper dosage and form. Intense services and comprehensive scope are other services provided by the institutional pharmacy. o  Ã‚   For what tasks might an institutional-pharmacy technician be responsible? o  Ã‚   How are medication orders processed in an institutional pharmacy setting? o  Ã‚   How do institutional and noninstitutional pharmacy settings differ? o  Ã‚   What patient issues might arise when working in an institutional pharmacy setting? o  Ã‚   Which issues may be unique to institutional pharmacy settings?
