ABSTRACT: This study was carried out to evaluate the effect of pretreatments prior different drying methods and temperatures on compositional quality of the dried mushroom. Oyster mushroom (Pleurotus ostreatus) was cultivated on rice substrate and collected samples were pretreated (steeped or blanched) by different solutions (0.1% sodium metabisulfite and 0.1 and 0.5% citric acid) and dried using oven at 50°C and 60°C, sun-drying at 30-35°C and microwave drying at 2.45 GHz until reached to…

2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

The study of inheritance at the at one of the smallest levels is referred to as molecular genetics and is utilized for many purposes, which include genes, genotyping, sequencing, cloning, etc. (Kelly, 2016). This allows for the ability to conduct DNA analysis revealing varying compositions and properties. For the following experiment the genomic DNA from Drosophila melanogaster, was utilized to be cloned and sequenced for either actin or 18s rRNA. In order to clone and sequence the specific…

The purpose of this experiment was to see if different fragrances affected a soap’s antibacterial properties. In this experiment, non-scented Alconox soap was used as the control. The experimental groups consisted of Joy lemon dishwashing soap, Dawn Escapes New Zealand Springs dishwashing soap, and the soap from the campus bathroom dispenser. The subject’s hands were washed with each of these soaps for approximately 30 seconds with each soap. The subject’s right hand was swabbed for each sample.…

Increase ventilation, particularly after bringing new sources of formaldehyde into your home. Use exterior-grade pressed-wood products (they’re lower-emitting because they contain phenol resins, not urea resins). Look for formaldehyde-free furniture and wood products. Other sources of indoor air pollutions are combustion products. Diverse indoor combustion sources contribute to the quality of indoor air environment. Indoor combustion…

During the Holocaust the Jews were tortured and kill. But were the benefits of science justified for the Jewish. Nazi doctors conducted almost as many as 30 different types of experiments on prisoners that were in the concentration camps. You will find out how the Holocaust start as well. They did these experiments to see what the German military could handle in war. You will also find that it wasn’t worth hurting and murdering people in the end. The Nazis started to target the jewish because…

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease in which there is a loss of motor neurons in the brain and spinal cord, this disease is incurable therefore leading to paralysis and death. The particular two studies discussed will be based on how biomarkers (a tool used by scientist to determine the biological pathways and the progress of the disease) can help find a cure for ALS by creating an effective drug and most importantly early detection. Mice were used as a transgenic…

disaccharides and polysaccharides barring exceptions should give a positive test for it (Harpercollege.edu 2015) . These give a positive test because hydrochloric acid dehydrates the carbohydrate to give an aldehyde . This aldehyde then condenses with phenol molecules in the Molisch reagent to give a coloured product which is most times purple or red. Based on literature all tested…

non-toxic ingredients, organic and non-GMO ingredients. 2) When you were coming up with your formula for Ladybug Jane, what surprised you as you did your research? I was surprised at how many lip balm products contain petroleum, beeswax, alcohol, phenol, and menthol,…
