(Table 1). The solution pH was measured using digital pH meter (Hanna instrument model HI 8519, Italy). Fourier transform infrared (FT-IR) spectra were measured on Nicolet is 10 FTIR spectrometer in the range of (4000 to 400 cm-1). Scanning electron microscope (SEM, Quanta 250 FEG, FEI Company, USA) at an accelerating voltage of 30 kV was used for evaluation of surface morphology and particle size determination. The specific surface area of the HAPNRs was measured by the BET-method (adsorption…

sample in order to examine whether there is semen contaminated by using the acid phosphatase enzyme method. (Mcewen & Regoeczi 2015). In order for a forensic expert to confirm the results, they would need to analyse the bodily fluids sample under a microscope. Phenolphthalein is used to test blood, it is a colourless substance which shows whether blood is present, and luminal is another test used by forensics as it is able to detect even the smallest drops of blood. The phadebas amylase test is…

learn how to operate the lab equipment. As mentioned above, a few of the machines might include a spectrophotometer, the machines that preform the polarized light microscopy, the Raman spectroscopy, the infrared spectroscopy, and the scanning electron microscope. They…

lining material. The three different surface materials were treated with Poly ethyl methacrylate monomer, Minute-Stain glaze, or mono-poly glaze. These different samples were compared after 30 days. Samples were analyzed with the use of scanning electron microscope. Initially the surface of all samples was intact. Fewer irregularities were seen in monopoly and Minute-Stain glaze treated samples. After 30 days, untreated liner and treated with monomer showed severe wear with exposure of…

Sample is slowly and carefully placed on the mixture to avoid air bubbles. Sample is clamped for 24 hours to allow it to stick. Sample is removed and is now grinded down to 30 m to become translucent and therefore become visible under microscope. 5.2.2 Preparation of a dyed sample Sample is cleaned and cut into a square of size 2X2 cm. Dye is prepared using 95 mg epoxy Resin, 0.3 mg blue Dye, 12.5 ml thickener, 12.5 ml thinner Epoxy and hardener mixture is prepared (used to glue samples…

1 Introduction Leaf spring is a suspension system for vehicles that were used in the old days. Originally, they were called carriage or laminated springs. This system was successful and genuine, used primarily on almost all vehicles until the 1970s and still on trucks and vans that carry heavy loads. The spring leaf consists of an arched, slender piece of steel that is arranged in the same material in smaller sizes and combined together to form a reinforced arc-like element. It is then attached…

1. Wright PS. in 1984 stated that there is sufficient evidence available for use of soft liner but because of its inadequate physical properties the use of soft liner is limited. The objectives of the study were: 1. Clinical success of the available soft liner material and their retrospective study. 2. The collection and measurement of data relating to a group of wearing soft-lined mandibular dentures for edentulous patients. 3. A three year longitudinal study of the clinical success of both…

patterns, and color schemes. We feel comforted by associations that remain constant. Familiarity makes for a comfortable existence. Anything mankind can’t visualize puts itself in a category of fear and discomfort. One could even argue that the electron microscope exists solely to aestheticize what ails mankind-- influenza, cancer, and the common cold now all have mugshots. CAT scans give an aesthetic to medicine and biology that’s been lacking since the inception of these fields. However,…

He took samples from frog skin and ran it through an electron scanning microscope. The results brought in information on a fungal infection from a fungus group called Chytrid. The weird thing about this discovery is that this fungus has never been seen before and they can only be found deep underground or in treetops…

Alzheimer’s Disease is a mental deterioration that usually affects the elderly but the signs and symptoms can come up in middle age. It can cause dementia and can hinder the person’s abilities of performing normal daily tasks of driving, self-care, and basic day to day duties. Many do not think that Alzheimer’s will affect them but the statistics are high. Alzheimer’s does not only effect the individual it has impacts on the family members and society. With research we take a deeper look on how…
