Calibration

compact spot for drug (Rf value of Cilnidipine and Chlorthalidone was 0.75 and 0.47 respectively). Densitometric analysis of Cilnidipine and Chlorthalidone were carried out in the absorbance mode at 230 nm. The linear regression analysis data for the calibration plots of Cilnidipine and Chlorthalidone showed good linear relationship with r2 = 0.991 for CILN and r2 =0.997 for CHLO , with respect to peak area in the concentration range 800-2400 and 1000-3000 ng per spot, respectively. The method…

The ruler that we used in this experiment had a range of 0-30 cm with a sensitivity of 0.05 cm. The ruler needs no calibration. Our other measuring device was the spring scale. The spring scale was used to measure the force of weight on each cylinder in newtons. The spring scale used in this experiment had a range of 0-2.5 newtons and a sensitivity of 0.025 newtons. To…

Testing the Validity of the Approach of Using Hydrogen and Helium Emission Spectra with the Rydberg Equation to Determine the Ionization Energy of Helium Michelle Plavnik Department of Chemistry, Emory University, Atlanta, GA, 30322, United States PAGE 2 ABSTRACT: The purpose of this lab is to determine how accurate the Rydberg equation is at modeling helium transitions and finding the ionization energy from those transitions. To accomplish this aim, the spectra of hydrogen and helium were…

Next the power lab and the force transducer was setup and then calibrated. Recording for 5 seconds, adding 50 grams to the hook, and recording for another 5 seconds did this. The N-value was calculated and entered into the program, concluding the calibration. Next the calf muscle was connected to the force transducer, by placing a hood through the achilles and the knee was clamped. Also an electric probe was put on the muscle. Then the super maximal stimulus was determined, setting the interval…

Two chromatographic methods were developed for the assay of the FDA approved lozenges containing dextromethorphan hydrobromide (DXT) and menthol (MNT). The first was a green HPTLC method which depends on using Merck HPTLC aluminum sheets of silica gel 60 F254 and methanol-ammonia (10:0.1, v/v) as mobile phase. This was followed by densitometric measurements of the spots which were retained at 0.28 ± 0.01 for DXT and 0.76 ± 0.02 for MNT scanned at 210 nm. The method was found linear over the…

the ten week period approximately 400 sound level sample points, 60 noise dosimetry samples and 20 air samples were collected. I developed and implemented a pump cycling/battery maintenance program. It was also necessary to coordinate equipment calibration and repair. I assisted with GHS safety data sheet (SDS) generation and Label Vendor Identification. I also developed and implemented the SDS Back-up Process. I served as the sites backup Fit Tester. During the majority of the ten week…

therefore make those jobs available to whoever needs them. Therefore, sweatshops tend to aid in supplying millions of jobs to individuals living in poor regions worldwide (Grey, 2010, para. 1). Accordingly, governments tend to also benefit from the calibration of third party companies operating within its borders since those companies are forced to pay for taxes and other governmental services. Additionally, the integration of sweatshops into a country’s economy also benefits individuals. Grey…

CHAPTER 1: INTRODUCTION Diabetes, also known as Diabetes Mellitus (DM) is a serious medical condition that occurs when the body becomes incapable of regulating blood sugar level. This results in several chronic complications to develop in the body, including the most prevalent Diabetic Neuropathies, along with vascular disease, slow healing and diminished response to infection over time (Brem, Sheehan & Boulton 2004). Due to severe damage of nerve cells throughout the body, diabetic patients…

“Classical conditioning describes a process where a stimulus becomes associated with, and is used to predict, the occurrence of an important event which subsequently leads to an increase in response behaviour” (Malim and Birch, 1998). This concept was first extensively studied and experimented in the early 20th century by a Russian physiologist called Ivan Pavlov. Pavlov worked on three different research problems during his long and rewarding life, but he was most interested in digestion…

Assessment forms an integral part of both education and real life, assessment of understanding, peer feedback, and self-assessment form a central part of social processes and therefore mediate the development of intellectual abilities, construction of knowledge, and formation of a students' identity (Shepard, 2000). Assessment of learning also provides a metacognitive awareness for the student and creates accountability for pedagogical strategies and curriculum policies. Metacognitive awareness…
