Introduction Lead aprons are available in the healthcare facilities to provide protection from unnecessary exposure of X-radiation to the patients and workers during radiology procedures usually done for diagnostic purposes. Body is shielded by the protective garment called lead apron from the harmful radiation during the medical imaging. Lead apron is found to be effective […]
Polymerase Chain Reaction (PCR): Optimization Parameters
IGHODARO OGHOGHO UYIOSA Polymerase chain reaction (PCR): Evaluation of different optimization parameters for appropriate PCR process. Abstract PCR is a method used to produce relatively large amounts of a specific DNA sequence. The productivity of PCR method depends on different reaction conditions such as the concentration of the DNA template, concentration of magnesium ions, DNA […]
Petrogenesis of the Basalts From Lanjiafan Formation
Chapter 5: Petrogenesis of the basalts from Lanjiafan Formation and Evaluation of Tectonic setting Most trends on variation diagrams are the result of mixing. Below consider some of the more important mixing process. 5.1 Alteration It is observed from the field evidence as well as petrography that the studied basalts are experienced varying degrees of […]

Finding the Gravitational Constant: Cavendish Experiment
Matt Cramb The experiment explored the story of gravity, how it was discovered and derived from observations and experimentations, and attempted to recreate those initial tests. This was done to determine whether an increase in mass will increase the force of gravity, a statement which was supported by the experimental data, despite the numerous flaws […]
Detection of Phenylbutazone in Race Horses
Forensic Bio analysis Detection of Phenylbutazone in Race Horses Phenylbutazone (C19H20N2O2 see figure 1 below) is a non-steroidal anti-inflammatory drug. Bute as it is more commonly known, is widely used for the treatment of bone, joint and soft tissue inflammation in horses. It was used in the treatment of ankylosing spondylitis in humans, but after […]
Effect of Alcohol on Reaction Times: Experiment
The experiment tested whether alcohol had any effect on reaction time.Abstract Objective: The experiment tested whether alcohol had any effect on reaction time. Method: Subjects were required to identify the threshold at which a flickering light became constant (critical flicker fusion threshold) using a computerised flicker fusion system. Frequency increased at a rate of 4 […]
Knowing God Through Reason Or Faith Religion Essay
The desire for mankind to know God, implicates that all humans are designed to have a conscience in them that enables communication with their creator, as stated in (Genesis 1: 27). This essay will explain both arguments of knowing God by faith or reason, examples relating to both sides will be given in order to […]
Word frequency and generation effect in free recall
The area of cognitive psychology which is interested in generation effect is quite wide. Many experiments were done but also many theories made on them. To widely examinee the whole subject about generation effect in free recall, it has to be explained what generation effect means. Very meaningful experiment was done by Slamecka and Graf […]
