Abstract:

The main purpose of conduction the photosynthesis experiment was to carry out paper chromatography in order to determine the pigments involved in photosynthesis. Secondly, the absorption spectrum for chlorophyll was determined in order to determine the wavelengths useful in photosynthesis. Third, the experiment aimed at examining chloroplasts utilizing the Hill reaction. Lastly, the relationship between light, photosynthesis, and chloroplasts was to be investigated. This would help in providing insight into the electron transport and carbon fixation phases of photosynthesis. Paper chromatography was used to separate pigments in plants. Xanthophyll was found to travel the fastest. The absorption spectrum of Continue reading...

Constant head permeability test for sand

Objective of this experiment is to determine coefficient of permeability of sand by Constant head permeability test.

Description of Soil Samples:

The soil, used in the lab experiment, was coarse sand. The sand was dry, light whitish pink in color and there was no smell.

Description of Test Methodology:

Constant head permeameter, a graduated cylinder (250 cc or 500 cc), Balance- sensitive up to 0.1 g, Thermometer - sensitive up to 0.1 degree C, Rubber tubing and Stop watch were used in this experiment. At first weight of the plastic specimen tube, the porous stones, the spring, and the two rubber stoppers (W1) were taken. Then the Continue reading...

Phase I: Introduction Dementia is an illness that continually affects many families. Due to the need for intensive care, especially for patients with advanced state dementia, many families opt for nursing homes. Nursing homes can offer the much need care and attention to the needs of the patient. Nursing homes also offer skilled end-of-life care for the patients, hence the choice of the option for many families. As a nurse, I have a profession interest in the care of patients with advanced stage dementia. My interest is fueled by the need to ensure that people with advance stage dementia Continue reading...

A Process Analysis Essay
The pedal bicycle has been around for many, many years, ever since Da Vinci imagined the wonderful instrument for transportation and recreation. Even though it is a rather simple instrument when compared to other modes of transportation, there are still a few things that are necessary to understand in order to have a bicycle function properly. The most important, perhaps, is the ability to change a flat tire when the need arises.
Changing a flat tire is not a difficult task, but it is very important not only for regular maintenance, but also for on Continue reading...

Introduction

Atoms are those constituents of all the matters which are the smallest. Atoms are the main part of the element and the different elements have different atoms. Atoms also contain the sub-atomic particles. Among these sub-atomic particles, the three particles hold the significant importance and therefore are studied more. These sub-atomic particles includes proton, neutron and electron. The elements that are different possess different atoms in terms of difference in the number of these sub-atomic particles. Consequently, the number of subatomic particles in an atom is the basis for the characterization of the atoms elements containing the atoms. Most Continue reading...

Abstract

Three tests were made on the kerosene sample: (a) determining hydrogen content by Nuclear Magnetic Resonance [NMR], (b) determination of viscosity by U-tube viscometer, and (c) flash point determination by Pensky-Marten closed-cup tester. Results suggest that the kerosene sample has 13.73% hydrogen content, 7.706 mm2/s kinematic viscosity at -20°C (extrapolated using Sutherland Viscosity Law), and 52-53°C flash point. These parameters characterized the kerosene sample as aviation fuel in terms of heating value, degree of saturation, pressure drop in fuel lines, pumping characteristics and safe handling. All parameters passed the standards derived from aviation literature. These parameters could Continue reading...

Breathing is one of the main processes that sustain life. The termination of it, even for a short time, leads to the rapid demise of the body from oxygen deficiency - hypoxia. 'Cricoid pressure is a vital skill that should be performed during resuscitation with bag and mask and emergency tracheal intubation' (Hein, Owen, 2005). The virtuos skills, which are required to ensure the airway, are the integral part of the skills of every anesthesiologist. The anatomy of the upper respiratory tract, equipment and procedures of the airway management, as well as the complications of laryngoscopy, intubation and extubation Continue reading...

Diffusion, osmosis, and functional significance of biological membranes

Abstract
Diffusion is the process in which substances move from an area of higher concentration to an area of lower concentration. If a semipermeable membrane is involved in this movement then this process is known as Osmosis. Semipermeable membrane is any biological membrane in the body that is selectively permeable. These membranes protect the cell from external environment. These are also involved in the movement of molecules in and out of the cell. This movement of molecules result in the differences in concentration until an equilibrium is established. In this research, we have done experiments on Elodea cells to Continue reading...

PEME2010

Summary
The experiment is meant to study the carbon dioxide absorption process in a packed tower mechanism column. The pressure performance of a packed column was determined experimentally. The calculations shoed that the pressure difference between the top and bottom part of the column is directly proportional to air flow rate; as the water flow rate increases, the pressure difference increases as well. However, at high water and air flow rates, the column flooding appears. The rate of carbon dioxide absorption was calculated. It was determined, that absorption increased carbon dioxide concentration by 80%.

Introduction

A motorcycle suspension system helps in dual manner – support the vehicle brake and maintain the balance. This directly translates in to the bike’s safety and provides suitable comfort and balance to the rider. The function of the suspension system is to absorb the shocks while handling, breaking or while simply riding on the road. The vibrations caused while running the vehicle are ‘dampened’. Thus, the name ‘vibrations damper’ for the shock absorbers. The rear suspension, also called “rising-rate” is popularly used in motorcycle design and manufacturing. Here the wheel is suspended by Continue reading...
