Safety Working Procedures Lab Report

When i was 12years old i was going to sience we were doing are safety lab so we were going to all the stuff she show us the fire ectercure and it went off and hit the table then went in my eye i think i was sharked that it went off i jumped up and run back and forth i was freaking out then my teacher got me and ran me to the eye washer and i walk back and was trying to help clean the mess but my eye buren bad so i went to the clinic they wach my eye out and told me to take off my shirt and she gave me one she call my dad to let me talk to him my eye was all red. I think my teacher thought that the pin was till i the think when she thought it was was saved to pick it up and pick it up and it went off i know she feel so so bad.She was saying

Experiment #6 allows parents to see how much their child is interested in toys or objects. Counting how many seconds the infant stares at them can help reveal what is inside his mind. In this experiment, parents observe the length of time the infant pays attention to a given toy before he looks away from the object. The baby is introduced to certain toys several times until the baby loses interest, or habituates, to them. This simple experiment can tell parents how an infant’s brain works and how this may affect his learning skills in the future.

The purpose of these experiments was to familiarize one’s self with laboratory equipment as well as becoming competent with different types of units as well as different methods of measurements.

When we write, “drill a 3/8” diameter, 1” depth hole in the center of the dowel”, the reality is a lot different. First, we need to find 3/8” tap size that is specifically designed for wood. Then, we need to find the center point of the dowel and figure out how to drill a hole perfectly centered. The process took us 2 hours in lab to figure out the most efficient and effective way to do such simple task. Because of time constrain, we decided to finish the system later in the day.

Data were collected in September and November 2017 at the Elk Valley Preserve and Field Station in Banner Elk, NC. The preserve is located at 36°10'17.2"N 81°54'45.9"W, in Avery County in western North Carolina. The area is a mixed deciduous forest at an altitude of 1,127 m above sea level. Data were collected in early fall, during which temperatures average around 10-18 degrees Celsius. Summers in Banner Elk are typically mild, with temperatures averaging 21 degrees Celsius, and winters are cold and snowy, averaging near zero degrees Celsius. During the months of September and November there is an overall average precipitation of 12-25cm.

Studies show that unwashed or lightly rinsed vegetables can harbor pathogenic bacteria and have been implicated in numerous foodborne infections. The objective of this experiment was to obtain a quantitative viable plate count of enteric bacteria present in a sample of broccoli sprout water. To enumerate the number of bacterial colonies present in the sample, we performed serial dilutions of broccoli water spread onto MacConkey Agar plates. MacConkey Agar is a selective and differential media. It is used to select enteric bacteria and differentiate lactose-fermenters from non-lactose fermenters. Utilizing this process illustrated the potential amount of foodborne illness causing bacteria present on foods, specifically fresh broccoli

Introduction: The Scientific Method is a method utilized by scientists all around the world. There are many reasons for its universality such as its aid in objectively answering questions and coming to valid conclusions, its demanding organization which forces scientists to form hypotheses and carefully follow and document their methodology to the letter, and lastly it aids in the validity and repeatability of the results of experiments. In general the scientific method, aids scientists in answering the uncertainties that plague life objectively and in a way that can be repeated by other scientists globally so as to uphold or disprove results.

Lab safety is also enhanced by practicing proper disposal. Items in the lab can expose high risks of danger to people. Proper disposal minimizes the potential risks in the lab by keeping the items in secure places. Disposal bins are utilized in this exercise such as the biohazard bin, the regular trash bin, the sharps container, and recycling bin. Each bin is designed for specific items (Hill et al. 321). For instance needles, used scalpel blades, and glasses are disposed into the sharps container. Proper disposal ensures that objects and materials in the lab are disposed of in the right bin. Exposure to harmful used materials and objects is minimized by implementing proper disposal. As a result, lab safety is enhanced, and individuals are

Management will evaluate the significance of nonconforming work and notify clients in writing within three days of the investigative conclusion. Management will document to the client how the reported test results were affected. The laboratory Corrective Action Report will indicate the name of laboratory personnel who notified the client(s).

Initially, all participants were briefed on what the experiment entailed and the goals of the experiment. After the participants were briefed they were told to sit in an area distant from the other participants and to drink their designated coffee.

Nanoparticles adhesion to the bacterial surface leading altering the properties of membrane. The small size and the large surface area of nanoparticles give power to form strong connection with the surface of microorganism (Wong and Liu, 2010). Now, the mostly popular understanding is that SNPs with diameters less than 20 nm get attached to proteins with sulfur group of the membranes of bacterial cell resulting in increasing the permeability of the membrane, which lead to bacterial death (Morones et al.,2005).

about the experiment they were assigned to perform at home prior to class. This experiment required

1-Ladder consist of 13 double-stranded DNA ranging in size from 100 to 1500 size bp .

In our lab, we had several tasks to perform. The first task we needed to fulfill

MALDI-TOF mass spectroscopy (1, 3, 4) has been presented as a real outlook changing innovation in microbiology (2, 3, 4). Today it as of now is set up as the standard recognizable proof innovation for developed microorganisms in most clinical labs in Europe and in USA and Asian countries (3). MALDI-TOF MS has been extensively embraced by routine clinical microbiology research centres for bacterial species distinguishing proof (4). The major pros of MALDI-TOF of MALDI-TOF mass spectroscopy(1) compare to old traditional methods including less time consuming, reduced consumable expenses, and enhanced consumable expenses are mostly recognized and have effectively changed work process in numerous research facilities(3,4). In compare to atomic methods are considered as highest quality level for microbial distinguishing proof yet for the most part are costly, require significant manual communication and regularly are tedious(3,4), MALDI-TOF mass spectroscopy(1) is quick with a basic example arrangement strategy, however offers a comparable nature of data(3,4).
