Concentration. Pleurotus eryngii was cultivated on four different sterilized agro wastes as wheat, rice, sugarcane and wood. Wheat substrate gave the maximum yield of P. eryngii fruiting bodies (63.4 and 11.3 gm) for 100 gram of substrate for first flush and second flush respectively. Also, cultivation of tested mushroom on wheat substrate produced high quantity of polysaccharides (0.703 mg/ml) which was colormetrically evaluated by Phenol-Sulfuric acid method. The structure of endo-polysaccharides was studied by Fourier Transform-Infrared spectroscopy (FT-IR) was indicated the presence of O-H, C-H, C-O-C, CH2 and C-O bonds that indicated the appearance of C1-C5 by 1 H & 13 C NMR. Polysaccharides analysis with HPLC indicated that it is consisting of glucose, galactose, glucournic acid, ribose, rhamnose and mannose. Polysaccharides were obtained from Pleurotus eryngii approved high antioxidant activity by Di phenyl Pichryl hydrocarbon (DPPH) radical scavenging activity which increased by increasing the concentration of polysaccharides. The obtained polysaccharides had IC50 at 0.32 mg/ml.

Laplace Adomian decomposition method, Caputo The present work offers a new model of (n+1)-dimensional fractional Burgers’ equation ((n+1)D-FBE) and presents a comparative numerical study of three efficient semi analytical techniques for solving the ((n+1)D-FBEs). These techniques include the Laplace Adomian decomposition method (LADM), the Laplace variational iteration method (LVIM) and the reduced differential transform method (RDTM). The suggested approaches consider the use of the suitable initial conditions and find the solutions without any discretization or limiting traditions. Furthermore, their solutions are in the form of quickly convergent series with easily calculable terms. Numerical studies of four numerical applications are provided to certify the effectiveness and reliability of the suggested approaches, also to compare their computational effectiveness with each other and with other supplementary methods in the available literature. In addition to explore the properties of the solutions when changing the fractional derivative parameter. Numerical results demonstrate the effectiveness and accuracy of the suggested methods.

are situated in the northwestern portion of the Abu-Gharadig sedimentary The is ENE-WSW-oriented, and ranges in age between the Late Jurassic and Early Cretaceous. The presence of sandstone streaks in the Abu Roash “C” Member of the Abu-Roash Formation, which has a relatively high resistivity signature in the electric logs in most wells within these fields, is the primary reason for investigating its petrophysical parameters in order to describe the main characteristics of these sands and to assess their ability for hydrocarbon accumulation as well as production. The aim of this study was completed based on information from well log data from nine boreholes. The petrophysical evaluation of the BED3-8 well reveals approximately 87.4% oil saturation within the reservoir rock, whereas the hydrocarbon saturation of the other wells in BED-15 is estimated to vary between 56.1 and 78.8%.

Wadi Zaghra granitoid intrusion comprises quartz diorite, granodiorite, tonalite, monzogranites, syenogranite, and alkali feldspar granites. Geochemically, Zaghra granitoid rocks are peraluminous magma and exhibit a transitional calc-alkaline to alkaline magma type affinity of I type, as well as island arc setting belonging to the volcanic arc regime. Microprobe data of amphiboles are calcic-type and have the composition of actinolite, actinolite hornblende, magnesio-hornblende, and edenite. Biotites are Mg-rich and meroxene types. Plagioclase has a composition of albite and oligoclase fields with minor andesine. According to mineral chemistry, Wadi Zaghra granitoid rocks crystallized at an average pressure of about 1.4 Kb and a temperature range of 650-700 °C.

Cellulases are enzymes that catalyze the bioconversion of cellulose molecule into monosaccharides (simple sugers) such as beta glucose or shorter polysaccharides and oligosaccharides. Most fungal cellulase enzymes degrade the cellulose molecule and several other polysaccharides into monosaccharides. In this study, twenty fungal species were isolated from several locations in Al-Gharbia governorate, Egypt. The soil samples are collected from various plant rhizospheres (rice, wheat, bean, sugar beet, and pea). These fungi were identified and referred to seven different genera " Trichoderma, Aspergillus, Rhizopus, Cephalosporium, Fusarium, Penicillium, Mucor". All identified fungal species were tested for cellulolytic activity in the solid medium. Out of twenty fungal species, seventeen species showed cellulolytic activity and the highest activity was recorded in Trichoderma viride (Rs-4) (67.2 U/ml) and Aspergillus sydowii (Rs-2) (52.1 U/ml). The selected cellulolytic fungal enzymes were carboxymethyl cellulase (CMCase), β-glucosidase (βGase) and filter paper cellulase (FPase) in the liquid medium. All tested fungi showed significant activity

Biodegradability, Biocompatibility, Direct polycondensation, poly L-Lactic acid, Average molecular weight. Significant scientific and engineering efforts have been made in the discovery, development, and application of polymers as a result of social and economic progress. One of the most promising biopolymers is polylactic acid (PLLA), which may be manufactured from nontoxic renewable feedstock. Due to its qualities including biocompatibility, biodegradability, mechanical strength, and processability, PLA has become a crucial polymeric material for biomedical applications. By fermenting sugars sourced from renewable resources like corn and sugarcane, lactic acid (LA) can be produced. Thus, PLLA is a non-toxic, eco-friendly polymer with properties that allow for usage in the human body.

Araba, Gilf and Abu Ballas formations contain clay and iron sediments are detected by the processing techniques to the remote sensing data of Landsat-8 OLI/TIRS. The false color composite, band ratio and principal component analysis techniques are adopted as the image analysis algorithms. The stratigraphic detailed studies are performed, and an improvement geologic map is produced. The Araba Formation is represented by about 20 m thick, the thickness of the Gilf Formation ranging from 10 to 35 m where Abu Ballas Formation has 25 m thickness in the study area. Three clay-beds are recorded in Gilf Formation. Thesis clay beds are a character of the so-called ball-clay shale, currently of economic use in ceramics industry. More than 108 samples from clay and iron sediments are collected and spectrophotometry study was performed. A high content of clay minerals and iron oxides are reported in the spectral curves which helped to map the clay and iron minerals in a satisfactory scale in the study area.
