Abstract The quality of crude palm oil (CPO) needs to be considered ensure the food safety further processed products. Several characteristics CPO such as water content, free fatty acids, Cl, and Fe are known precursors for formation toxic compounds 3-Mono Chloro-1,2-Propane-Diol (MCPD) in A study was conducted determine effect activated rice husk charcoal used an adsorbent improving CPO. activ...
by standard histological methods and stained with haematoxylin and eosin. Microscopically, there was distension and vacuolation of Purkinje cells in the cerebellum (Fig 1) and of neurons in the cerebral cortex, thalamus, mesencephalon and spinal cord. Cytoplasmic vacuolation was also present in the epithelium of the pancreatic acinus and renal tubules, follicular epithelium of the thyroid, in h...
Introduction: Natural materials are more efficient and attractive than synthetic materials. In this study, the sound absorption behavior by natural kenaf composite and Micro-Perforated Panel (MPP) at low and medium frequency region was investigated. Material and Methods: Initially, the results of kenaf fibers with a thickness of 10 mm were validated by the Finite Element Method (FEM) based on ...
1. A method has been outlined by which the enzymes of hemolytic streptococcus may be extracted with comparative ease. 2. The peptolytic enzyme is active between pH 4.4 and 8.7 with an optimum action at pH 7.2. It is destroyed in neutral phosphate solution at a temperature of 57 degrees C. continued for 10 minutes and at pH 5.0 deteriorates slowly at 37 degrees C. Concentration experiments with ...
Objectives: Ceramics have advantages such as optimal esthetics and biocompatibility. However, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of pH, which increase their risk of fracture. Since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Abstract Green extraction processes to obtain high value bioactive compounds from raw natural materials and wastes has gained attention the past few years. In present study, we investigated a Natural Deep Eutectic Solvent derived two products, namely choline chloride glucose as potential solvent for of tannin spent coffee ground(SCG). A was used coagulant with Poly aluminium chloride(PAC) flocc...
In this study, the photocatalytic and bleaching properties of pure and doped titanium dioxide nanoparticles with 1%, 3%, 5% and 10% Ce dopant were studied using Ce(NO3)3 precursor. The results showed that the highest methylene blue degradation of the sample with 5% cerium impurity was 97% in neutral medium (pH=7) after 75 minutes. The bleaching response to wastewater treatment with 5% cerium im...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
most popular sources for electromagnetic waves. however, there are many concerns regarding their biological effects on the body, especially the central nervous system. therefore, the aim of this study was to evaluate the effects of cell phone radiation on histology of the cerebellar granular cells in the neonatal rat. materials and methods: we selected some wistar rats. then, we randomly divide...
