Decay Reports Samples For Students

Abstract

This report is supposed to address the relationship between the characteristics of Coarse Woody Debris (CWD) and its associated invertebrate community. For the purposes of this report, students will be introduced to data collection methods as well as identification and enumeration of soil invertebrates related to coarse woody debris. Coarse woody debris can be said to be the dead woody particles found mainly above the soil surface. These dead woody materials are always in different stages of decomposition depending on when the dead material started decomposing.
For the purposes of this report, only dead wood above 8 cm ...

ABSTRACT

In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen.
The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency.
The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.

Introduction
Passing and receiving information from one being to another is based on how well a person can remember. Often people tend to forget things and are heard saying “oh, my memory failed me.” The big question here, however, is how exactly does the memory work. How does the person’s memory, manage to keep information passed on to it, for sometimes a long time whereas there are times when it just goes blank in second? It is important to know the message storing part if the brain. This is in the modern world, known as the working memory.

1. Abstract
The sodium iodide scintillator detector is a very important type of inorganic scintillators. The main function of this scintillator is to detect gamma rays by interaction of ionizing radiation and the materials of that scintillator. In this experiment, we learned the applications of this detector and how the process of detecting happens.
2. Introduction
This lab experiment is designed to make the student learn about scintillation detectors and how do they detect gamma and beta ray such as the effect of a sodium iodide NaI(Tl) scintillator. This type of detector the scintillation materials interact with ...

The worst nuclear incident on the land of the US happened on March 28, 1979, as it was the famous Three Mile Island accident, which was a nuclear meltdown in one of the two reactors of Three Mile Island in Dauphin County, Pennsylvania, US. The incident was also rated a five, in the group “Accidents with wider Consequences” on the International Nuclear Event Scale, which has seven as the maximum rate. The accident itself began with the halting of the secondary systems of non-nuclear group, which resulted with the failure of primary system`s relief valve, which was operated by a pilot. ...

Physics practical report: determining the range of a radiation and the energy content

Introduction
Most of the radiations emitted by sources usually emanate from radioactive isotopes. These isotopes may be naturally radioactive or the emission may be induced by an external source of energy. Natural isotopes are mainly elements whose atomic mass exceeds 208. For this reason, the atomic size is very large creating an aspect of imbalance in charge within the atom. The highly positively charged nucleus does not feel the same magnitude of negative charge effect from the electron cloud surrounding the nucleus. This makes the nucleus to disintegrate naturally to release some energy as it scales down the ...

This paper gives a report on the experiment performed on the deformation of bars under bending. During the experiment, the deflection of bars was observed when external pressure was exerted on them. The data obtained represented the quality of the bars which wee used in the experiment. Hence, it can be used in determining the quality of their work as recommended. The production of quality work can be of a great benefit to all the users of these bars. Meaning, such experiments should be conducted to gauge and determine their performance. Only the high performing bars should be used.

Ever since the 1920s and 1930s, the allure and absorption with the metropolitan life and the images related to it has resulted in an increased interest in the artistic rendition of urban images in various forms (Alifragkis and Penz 221). Whether in the moving image works of famous urban story tellers, such as Woody Allen, or still image works of admired photographers, such as Eugene Atgets and Man Ray, the interest in urban images is here to stay. The purpose of urban photography can be said to create visual appeal that summarizes the dynamics of modernity in an open ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

ABSTRACT
The RLC resonance in a circuit is a circuit in which the arrangements follow or consist of a resistor, inductor and capacitor. This lap report is not a confined order. It can take a different order, i.e. an inductor, a resistor and a capacitor thus LRC. This arrangement can be connected in series or parallel depending on the topic in question. In this circuit, RLC circuit resonance, form a harmonic oscillation for current in seen in the cathode ray tube, oscilloscope. This laboratory work or experiment tries to determine the behavior of an RLC resonance circuit in terms of the resonance frequency as displayed in ...

Introduction about the Radioisotopes

In this paper, a trainee is going to learn about the operation and handling of radioisotopes. Nuclear medicine is a branch of medicine using the radiation to analyze the function of the organs. This information is used by the physicians to have an accurate diagnosis. The radioisotopes are used to determine the affected organs in our body. The problems, like, thyroid, organs, bones, and many other organs can be easily imaged using this device. Over 10, 000 hospitals are currently using the radioisotopes in the medical field. The radioisotopes are the common isotopes used for diagnosis in technetium – 99. In the ...

The process of weathering deals with the breaking down of minerals, soils and rocks as well as synthetic materials as a result of contact with the atmosphere, biological entities and water. Weathering is slightly different from erosion, because it does not involve movement. Erosion involves the movement of water, wind, snow or other agents across minerals or rocks. Weathering simply takes place “in situ.” There are two significant types of weathering, chemical and physical. Each can involve a biological component, but the difference is that physical weathering has to do with soils and rocks breaking down as a result of directly contacting ...

This article provides astonishing findings about the role that bacteria plays in the health of periodontal disease. This article was written by Zhimin Feng and Aaron Weinberg, and it shows the interaction between the bacteria and human tooth. According to this article, bacteria and eukaryotic cells have a complex in interaction that involves a complex process. This process is meant to allow human beings live in harmony with bacteria that are within them. Periodontal diseases according to the article involve a series of infections on the periodontal tissues. This is a serious condition, and if not treated in early stages it can lead ...
