Before we proceed to examine more about Duty of Care, it will be helpful to consider the way in which this concept is used by the courts. Duty of care can be broken down into two questions:Â rst one which is general and determined as a matter of law and policy; followed by one which […]
Introduction This laboratory exercise is dedicated to studying forced convection, a crucial aspect of heat transfer. Understanding the importance and impact of forced convection on heat transfer problems is a crucial learning objective in the field. One of the key aspects of forced convection is the convection heat transfer coefficient (denoted as h), which is […]
Abstract Caffeine, (C8 H10 N4 O2) a white, crystalline alkaloid known as a nervous system stimulant found commonly in tea leaves and coffee, can be extracted using the method of sublimation with the use of Methylene Chloride (CH2Cl2) and Sodium Hydroxide; both can repeatedly rinse the green (unroasted) coffee beans from the caffeine. Keywords: Caffeine, […]
Introduction Agriculture which accounts for one fifth of GDP, provides sustenance to two-thirds of our population. Besides, it provides crucial backward and forward linkages to the rest of the economy. Successive five-year plan have laid stress on self-sufficiency and self-reliance in food grains production and concerted efforts in this direction have resulted in substantial increase […]
LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt, x. The salt is crystalline, deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt […]
This paper reports on the relative capability of the EOS M250 Extended platform to fully melt an 18Ni (â300â grade) maraging tool steel from sub-20 ”m powder. The work describes the investigation of scanning routines necessary to achieve satisfactory metallurgical integrity and shape manufacturing capabilities of the process. Solidification was observed to take place by […]
The chloride shift is basically an exchange of chloride ions through the capillaries of the system circuit. In the blood plasma, there is large amount of carbonic acid and when there is an increase in carbonic acid than the balance of hydrogen ions and carbonate ions dissociate to maintain a balance of homeostasis in the […]
Objective: In this lab we will analyze alum by two techniques in order to verify its identity. The melting point and the mole ratio of hydrated water to anhydrous aluminum potassium sulfate will be determined. Lab Procedure: Use a mortar and pestle to crush alum. Pack the alum in capillary tube, and then fasten it […]
The salt solution should be of greater density than that of pure water. Dilution of an Aqueous Solution: . Observe and note the colour and intensity of the drink (solution). I used Cherry Limeade drink for my experiment. The color of the liquid is a medium cherry red. The intensity of the color on a […]
Obtain a reference of temperatures effect on gas using Charlesâ law when heating a capillary tube in water on a heated hot plate.Then, cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed […]
Tobacco has a long history and has had a significant impact since first introduced to Western society in the 16th century. There is evidence that Native Americans were using tobacco long before the 16th century. They smoked through a pipe for special religious and medical purposes but the worldwide spread of tobacco was initiated as […]
Abstract Water is important to live, and the World possesses the fixed amount of water, which is found to occur naturally in various forms, such as oceans, lakes, rivers, streams, underground waters, ice caps, glaciers and rain. This water plays an important part in maintaining the balance of the worldâs weather, especially through the presence […]
Our objective is to purify dark and muddy water, transforming it into a clear and odorless liquid. To achieve this, we employ a filtering technique that eliminates particles from the water, enabling the fluid to flow through while retaining solid matter. The filter consists of pebbles, sand, and charcoal. This particular project was previously undertaken […]
Ready-Mix Spray plastering is a fast and high-quality building method supplied as “dry pre-mixed” for spray application by Plaster Machines. This technique has been widely used in Europe, UK, and the Far East for many years due to its economic benefits and quick application speed. The main differences between Traditional On-site Plaster, Ready-Mix Plaster, and […]
Biology Assignment Transpiration rates between Exotic vs.. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting […]
In this first lab we attempted to discover which of the materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose, sucrose if the only one which did not both bring condensation when heated and dissolve in […]
Recycling cigarette butts is a great way to turn these polluting chemicals into something useful. There are many hazardous chemicals in our environment; most of them can be located inside our own homes. Almost every household would consist of cleaning liquids like liquid detergents, mildew removers, insecticides and many other harmful chemicals; that is the […]
The aim of this experiment is to accurately prepare a potassium dichloride solution with various concentrations. We initially hypothesized that a higher concentration solution would result in a greater spectrophotometer reading. The results strongly support this hypothesis, despite a slight error in the spectrophotometer reading. The higher concentration solution yielded a reading of 1.066, while […]
Abstract Chili (Capsicum frustrates) is often consumed as a culinary spice due to its fiery and piquant flavor. Subsequently, it was revealed that chili possesses insecticidal qualities that are effective against mosquitoes. Zamias, which is known for its culinary use, also possesses properties such as being astringent, stomach, refrigerant, and antibiotics. Introduction and Background Chili’s […]
It Is an example of a flavoring which acts to create color. This research is being done to find out the potency of the extract of the leaves from the plant Camellia genesis as an ink. Nowadays, ink is a pigment in a liquid or paste form used as coolants and dyes. Also, they are […]
This chapter examines the materials and procedures utilized to collect essential information and data for the study. The bacterial isolates (Staphylococcus erasures, Escherichia coli, and Streptococcus) used in the experiment were obtained from the Institute of Biological Science, University of the Philippines Los Banos, Laguna. The bacterial isolates were subcultured on slants of Nutrient Agar […]
