1. What factors should be considered to provide maximal protection when people are exercising in the cold? To avoid excessive heat loss, our bodies use peripheral vasoconstriction, nonshivering thermogenesis, and shivering, which is usually not enough. Peripheral vasoconstriction We must also rely on behavioral responses like huddling behavior and putting on more clothing to help insulate our deep body tissues from the environment. During aerobic exercise, clothing insulation and exercise…

The Pierogi is a traditional Polish dinner dish consisting of crispy dumplings filled with a savory filling of potato, cheese, and other garnishes. The traditional recipe calls for simple ingredients and no fuss. Though actual preparation time and the cooking processes can be length, the pierogi itself is unassuming. In recent years, however, many people (Polish and non-Polish) have attempted to reconfigure the typical recipe to make it more exciting and even more delicious. Due to the…

Experiment 5: Separating Ferrocene and Acetylferrocene by Adsorption Column Chromatography AIM The primary goal of this experiment is to separate ferrocene and acetylferrocene using adsorption column chromatography. Additionally, a dry pack method with a micro scale column will be implemented, and the percent recovery for each compound will be computed. TABLE OF PHYSICAL PROPERTIES AND HAZARDS WITH STRUCTURES Ferrocene: - Physical Property: Solid Molecular Weight: 186.04 g/mole Boiling…

1. Introduction Urban greenery is usually being refer as parks or green space but others also claimed that it include rooftop, household garden and streetscape. In this millennium, the cities all over the world are increasingly urbanized. An in burst of immigrants from rural areas to cities is causing the cities to become congested and polluted. The rapidly expanding population and overcrowded slum have hasten the urban development where old buildings are demolished and deforestation is carried…

Oligosaccharide structures are strongly associated with their potential biological activities. Despite the biological activities of oligosaccharides have known for years, the lack of structural details limits the study of their potential applications. A rapid and effective method for identifying oligosaccharides is desirable yet the complete structural characterization of novel oligosaccharides remains challenging. The high polarity nature and highly branching, isomeric structures makes…

Introduction The engineering case studies presented in the fictional video provides profoundly different sets of ethical issues that are presented at various manufacturing companies that want to put up hurriedly manufacturing chemical plants. Engineering profession, just like in many other professions is confronted with many ethical responsibilities. The study is exceptionally important to the practicing engineers since it presents viewers with ethical guidelines that should be followed when…

In my perspective, the Poverty/Hunger issue is in a much better state than it was before but it hasn’t been resolved completely. This issue has two very different points of view, one that some of us have long worried about massive levels of future starvation, while others have forgotten that some people around the world don’t have food available to them and think it already has been resolved or diminished to the point where is no longer a big issue. Since the percent of people starving has…

Critical Reflection of microteaching Lesson Preparation A Comprehension of content The main purpose of this topic is to link it to the water cycle. The students would need to know that the water cycle is dependent on the condensation as well as evaporation of water. Also, due to the anticipation of certain misconceptions, the lesson was conducted in a way, such that, any misconceptions would be surfaced either during questioning or during the experiment. As a result, the teacher would need to…

very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and products of a synthesis. The components were purified and dried by evaporation and vacuum filtration. The separated compounds were then classified by determination of their melting points and 1H NMR. Results and Discussion In this…

The integumentary system is comprised of the skin’s two layers, the dermis and epidermis, as well as hair, nails, glands, and nerves. Underlying the skin is the subcutaneous layer, or hypodermis, this layer is not a part of the integumentary system but is vital to its function. Made up of a layer of loose connective tissue the hypodermis serves to connect the skin to underlying muscle and bone (142). The hypodermis also assists the overlying skin by supplying it with blood vessels and nerves…
