Purpose: The purpose of this lab was to compare the effect of using soap (antibacterial and non-antibacterial) and no soap on the growth of Escherichia coli (E.Coli). Hypothesis: If anti-bacterial and non-antibacterial soaps are added to a standard agar media before the E.Coli was introduced and incubated, then the portion of the plate containing the antibacterial soap will have the least amount of bacterial growth because the antibacterial soap contains a higher percentage of bacteria-killing…

These 3 set of people forms an equal partnership to drive the project in a collaborative manner. XP implement a simple but effective environment enabling all concern members to achieve solution and maximize productivity. The main idea is that the team rallies around the problem or case for the solution. Such development practice qualifies XP to be an agile method of software development. Citing Don well (1999, 2000, 2001, 2004, 2009) Extreme Programming improves a software project in five…

Pulmonary Embolism Did you know that just from sitting too long or just any type of prolonged immobility could sometimes be fatal? Life threatening 1/3 of people with undiagnosed and untreated Pulmonary Embolism don’t survive, can lead to Pulmonary Hypertension (PHTN), PHTN is a type of blood pressure that affects the arteries in your lungs and the right side of your heart. When lower extremities are horizontal for long lengths of time, the flow of the venous blood slows and blood can pool in…

particles move deeper into the respiratory system, inhaled particles that transverse these barriers continually are filtered down to a size of 1-5 micrometers. The nasal cavity begins the filtration process. It contains physical barriers that can filter particles down to 15 mircons. The first is vibrissae, which are hair cells that can ensnare over 95% of particles 15 micrometers or greater. Tactile stimulation of these hair cells can induce sneezing to forcefully expel foreign material. In…

Fitzgerald (2006) and Demere et al. (2008) provide evidence that the initial mysticete radiation did not coincide with the appearance of traits associated with bulk filter-feeding. Other studies suggest that previous timeframe estimates are incorrect, and that either the establishment of the Antarctic Circumpolar Current (Pfuhl and Cave 2005) or the radiation of the Mysticeti (Geisler et al. 2011) occurred much later…

Aims: The objectives of this experiment are to carry out the process of synthesising aspirin and reinforce both the skills of recrystallisation and melting point determination. In this experiment, we are supposed to measure the amount of aspirin collected to calculate the percentage yield of aspirin. Apart from that, we are also required to find the melting point of aspirin. Introduction: 1.1: aspirin Aspirin, also known as acetylsalicylic acid, is an aromatic compound containing both a…

These filters are programmed in our mind as a result of our cultural and educational upbringing as well as our significant life experiences. Our personal filters (like beliefs and values) determine our how our mind perceives all our experiences. These perceptions influence our mental and emotional state - leading to related behaviours…

The oldest recorded source of water was from a well. A well is a hole in the ground from which a fluid is withdrawn. Water wells can be dug, driven, bored, or drilled. These wells are constructed with a type of tool or machine, some go down farther than others, but they all serve one purpose. To bring water to people’s homes (World Book Encyclopedia). Water wells are the most common types of wells today. The water in these wells come from rain that soaks in the ground. The underground water in…

A filter in this context represents a barrier that is really hard for life to overcome. They come in various degrees of scary. One: There are Great Filters and we've passed them. Maybe it is way harder for complex life to develop then we think. The process, allowing life to begin, hasn't yet been completely figured out, and the…

schools. She argues that by restricting a student’s access to the internet there are more repercussions then there are benefits. She also points out that these filters are basically ineffective and have no real impact on the students. She then makes the case that students should be allowed free access to the internet without such strong filters because it is too problematic. K,Baron. (2014, June 26). What’s the impact of overzealous internet filtering in schools? Retrieved April 1, 2016, from,…
