OBJECTIVE To determine antiseptics evaluation by the filter paper disc method INTRODUCTION An antiseptic is a substance which inhibits the growth and development of microorganisms. Antiseptics are a diverse class of drugs which are applied to skin surfaces or mucous membranes for their anti-infective effects. This may be either bacteriocidal or bacteriostatic. Their uses include cleansing of skin and wound surfaces after injury‚ preparation of skin surfaces prior to injections or surgical procedures

Consultants covers a range of information in relation to braking systems. A disc brake has been collected and then examined for various analyses‚ including the history of the disc brake‚ material analysis‚ material alternatives that could have been used and material modification that took place on the component prior to assembly. The relevant OH&S issues associated with the manufacturing and material modification that took place on the disc brake is also highlighted. Other area’s this report covers includes

assist with lifting machinery. A herniated disc is characterized by leg pain greater than back pain that radiates below the knee that worsens with sitting (Casazza‚ 2012). In addition to this a herniated disc may be the underlying cause for the patient current sciatic nerve pain. As stated by Rothaus (2015)‚ the most common cause of sciatica is herniation of the disc in the lumbar region. Rothaus (2015)‚ also states that a positive SLR is also indicative of disc herniation.

investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly

1977). The average rate of catalase activity as seen in the chart above is 4.97 seconds while the orange is at zero seconds. During the experiment‚ none of the orange filtered discs rose in the given amount of time. From the data‚ one can see that the orange has no effect on catalase activity. Therefore the null hypothesis‚ the orange will not affect the catalase activity is accepted. Errors in the experiment could have come

RAM RAM is an acronym for Random Access Memory that is also known as volatile memory‚ because the data it holds is lost when the desktop PC or laptop/notebook computer using it is switched off. Briefly‚ RAM memory is used by the system to store data in the form of files for processing by a computer’s central processing unit (CPU)‚ also known as the processor. The amount of RAM memory used in modern desktop and laptop computers is expressed in megabytes (MB) and gigabytes(GB). A gigabyte (1GB)

this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper discs 5. Hole puncher 6. Pipette 7. Watch Glass 8. Stop Clock

McShane‚ Steen and Tasa (2015‚ p. 307) describe the directive style as a leadership style that is structured and specific. It involves specifying and providing psychological structure for the subordinates in terms of their job duties and also their performance goals. It also identifies how they are evaluated‚ rewarded and disciplined. Based on how the employees reacted to Donna’s decisions‚ the directive style‚ as described by McShane‚ Steen and Tasa (2015‚ p. 307) was not appropriate in this situation
