Household Cleaners - Lab Report Example Rub the hand with the cleaning agent for 18 seconds according to step 2. 6. Wash off the cleaning agent with 400ml of distilled water respectively. 7. Dried off with a kitchen cleaning paper. 8. Swab subject's left palm. The area of swabbing should be around 5x5 cm (square in shape). 9. Repeat with subject's right palm using a new swab. 10. Follow the steps as in the graphic (Merck, 2007) and measure the relative light unit by using the luminometer. 11. Record the reading on the luminometer. Result The purpose of the experiment is to determine the most effective agent to clean off germs on hand. Results collected will be tabulated as in table 1. Average and standard deviation are determined. Table 1: Tabulation of result. Cleaning Agent Subject Handwash shampoo Detergent Dish Cleaning Liquid Lemon juice 1 Left Right 2 Left Right 3 Left Right 4 Left Right 5 Left Right 6 Left Right 7 Left Right 8 Left Right 9 Left Right 10 Left Right Average Standard Deviation Then, the average RLU value of this will be plotted on graph as followed (figure 1). The higher relative light units reflect a higher bacteria count on the hands. The almost linear relationship between the relative light units and the total number of counts were proven by Merck (2007). Figure 1: Relative Light Units on hands after washing hands with different cleaning agents. The lemon juice might be the least effective cleaning agents among all cleaning agents. That is because it does not contain any antibacterial properties. But for handwashing shampoo, detergent and dish cleaning liquid, they contain -hydroxy-2',4,4'-trichlorodiphenyl ether (commercially known as triclosan), a common...This compound inhibits fatty acid synthesis in bacteria, thus preventing the reproduction of the bacteria. Fatty acids are needed in the synthesis of bacteria cell membranes. In conclusions, the result is estimated to refute with the hypothesis. Lemon juice is the least effective cleaning agent during handwash. The most effective would be detergent. This is due to the concentration of the active antibacterial compound in the cleaning agent. Lemon juice does not contain any antibacterial compound. It just bring down the pH of the surface and suppress growth of bacteria but do not kill them. Meantime, the RLU values would give a reliable result on the effectiveness of the cleaning agent. Other than using a luminometer, another way would be to determine the number of bacterial growth by microbiological plating method. This methodology however would take more than one day time to obtain the result. The advantage over a luminometer is that it can identify the type of microorganisms found on the hand after washing. This can be done by biochemically testing the colonies grown on the agar plates. Anyhow, the design of this experiment does not reflect the effectiveness of all types of similar products. It only gives a general idea.

Analyse the Motivational Problems in MagNet Corporation Research Paper

Analyse the Motivational Problems in MagNet Corporation - Research Paper Example   MagNet Corporation is a new start-up organization and has strength of 35 employees Existing in the market for two years, the company is heavily dependent on Information Technology (IT) tools MagNet mainly operates in the software market and provides educational software to colleges and universities based on Oracle database engine With excellent performance, early entry in the distance education market and two years of successful marketing, the company has been able to penetrate 5% of the market and increase their employee strength from 5 to 35 within such a short span However, with increasing demand in the clientele, the company is also facing problems to the main efficiency in its regular administrative processes where personnel are observed to lack motivation and are also observed as inefficient in change adaptation Business situation After evaluation and analysis of the company’s General Administration Department, i.e. Department C, it has been found that despite its wo rkforce constitutes potential employees, they lack on few motivational grounds and have to face a higher level of stress in order to accomplish the target to boost up the sales from 5% to 10%. Job role segregation has also been viewed as a major problem where the sales representatives rely heavily on the technical department, which makes them a slow learner and increases the burden on the technology department. Many of the sales force has also demanded training as mandatory for their development. In precise, the business situation observed in Department C of MagNet exhibits the need for better coordination amid the staff at the departmental level, motivation needs to boost their change adaptation behavior and understanding of the organizational success requirements. The stressors in this situation can be identified as the growing pressure from the clientele, absence of a specific HR policy framework and limited job commitment deciphered by the employees. Technical situations The ope rational processes in MagNet have been heavily dependent on modern technical instruments, which have in turn also affected the efficiency of the administrative department. Even the communication between the employees and managers happens via e-mail, with lack of interaction that further limits the scope of the supervisors to motivate their subordinates continually and efficiently. The personnel in Department C have also been heavily dependent on the technical support team to respond to the customer’s questions, especially those regarding new products as the employees in this department lack in efficiency to learn about new products and services within a short span of time. Solutions From a critical understanding of the situation, it can be observed that employees in Department C indeed require rigorous training focused on developing their learning, change adaptability and technical skills enhancement. Correspondingly, the company applied Maslow’s needs hierarchy theory and McClelland’s theory of motivation that has efficiently pointed-out the individual motivational needs of the staff members. Based on their performance appraisal as well, the company addressed three employees to be trained and has given formal written warnings to some of the employees so as to motivate them to perform better.  Ã‚
