In this paper, the impact of magnetic force, rotation, and nonlinear heat radiation on the peristaltic flow of a hybrid bio -nanofluids through a symmetric channel are investigated. Under the assumption of a low Reynolds number and a long wavelength, the exact solution of the expression for stream function, velocity, heat transfer coefficient, induced magnetic field, magnetic force, and temperature are obtained by using the Adomian decomposition method. The findings show that the magnetic force contours improve when the magnitude of the Hartmann number M is high and decreases when rotation increases. Lastly, the effects of essential parameters that appear in the problem are analyzed through a graph. Plotting all figures is done using the MATHEMATICA software.

Fuzzy numbers are used in various fields such as fuzzy process methods, decision control theory, problems involving decision making, and systematic reasoning. Fuzzy systems, including fuzzy set theory. In this paper, pentagonal fuzzy variables (PFV) are used to formulate linear programming problems (LPP). Here, we will concentrate on an approach to addressing these issues that uses the simplex technique (SM). Linear programming problems (LPP) and linear programming problems (LPP) with pentagonal fuzzy numbers (PFN) are the two basic categories into which we divide these issues. The focus of this paper is to find the optimal solution (OS) for LPP with PFN on the objective function (OF) and right-hand side. New ranking function (RF) approaches for solving fuzzy linear programming problems (FLPP) with a pentagonal fuzzy number (PFN) have been proposed, based on new ranking functions (N RF). The simplex method (SM) is very easy to understand. Finally, numerical examples (NE) are used to demonstrate the suggested approach's computing process.

Hydromorphometric analysis as a method is considered one of the most reliable and used methods in solving hydrological problems. Where it is possible to know the volume of runoff and the rest of the elements that enter into the water balance. Geographical Information System and Remote Sensing is the technique that used the hydro-morphometric analysis of the Wadi Al-Mohammadi basin. Wadi Al-Mohammadi, located in the Western Desert, is one of the main valleys that flow into the Euphrates River. It is considered an important basin, because of its many characteristics, including its relatively large area and the amount of water drained through, which is used mainly in watering livestock and agriculture, in addition to industrial purposes such as the production of washed sand, gravel that scattered on both sides of the valley. The hydrological analysis included several steps, which gave the results of the flow accumulation with the highest value in the lower part of the basin. The results represented by form characteristics confirm that the shape of the basin is far from the round shape, which reflects the basin’s characteristics with the regular surface flow in time and relatively low drainages. Wadi Al-Mohammadi basin has reached the 5th order to flow into the Euphrates River. It has two types of drainage patterns, the dendritic pattern, and the parallel pattern. Wadi Al-Mohammadi basin is categorized as extremely low drainage density, very low drainage frequency, very coarse drainage texture, lower infiltration number, and low relief slope. Based on the results, the basin is characterized by an almost flat plateau surface, with a gradual slope homogeneous and good permeable soil conditions, and in other parts influenced by the structural phenomena under the surface, the high permeability of sediments over which streams pass, higher the infiltration and lower runoff.

Oxidative stress and inflammation are connected to the development of metabolic disorders, such as diabetes. Diabetic-related oxidative stress is caused by the overproduction of oxidative-free radicals, which have been implicated in the mechanism of inflammation and damage to tissues. Our study aimed to investigate the effects of ubiquinone treatment on serum indicators of oxidative stress (malondialdehyde (MDA)), inflammation (interleukin 6 (IL-6)), vascular homeostasis (nitric oxide (NO)), and myopathy (myoglobin (MB)) in addition to measuring blood components parameters in streptozotocin-induced diabetic rats. Rats were separated into three groups; negative control group (N), diabetic control group (D), and ubiquinone-treated diabetic group (T). After 21 days, the blood and serum samples were taken to evaluate fasting blood glucose (FBG), MDA, IL-6, NO, MB, and hematological parameters. In hyperglycemic rats, the levels of FBG and serum levels of IL-6, MDA, and MB significantly increased, while NO levels decreased. Hyperglycemic condition significantly lowered the count of WBC (P = 0.0098) but insignificantly decreased values of platelets and RBC. Ubiquinone treatment significantly reduced blood glucose, IL-6, MDA, and MB levels in diabetic rats and raised NO levels. The effects of ubiquinone on WBC (P = 0.648), RBC (P = 0.001), and (P = 0.398) were insignificant, and only minor variations in WBC and platelet levels were observed. Our data support that ubiquinone supplementation could reduce proinflammation, oxidative stress, and myopathy markers and elevate NO levels in diabetic rats. The current study indicates ubiquinone may positively impact diabetic complications; however, additional research is required to determine its therapeutic benefit when added to standard diabetes treatment.

Abstract In the present article, Nano crystalline SnS and SnS:3% Bi thin films were fabricated using thermal evaporation with 400±20 nm thickness at room temperature at a rate deposition rate of 0.5 ±0.01nm /sec then annealing for one hour at 573 K for photovoltaic application. The prepared samples were characterized in order to investigate the structural, electrical, morphological, and optical properties using diverse techniques. XRD and SEM were recorded to investigate the effect of doping and annealing on structural and morphological possessions, respectively. XRD showed an SnS phase with polycrystalline and appeared to form an orthorhombic structure, with the distinguish trend along the (111) grade, varying crystallite size from (19.45-25.95) nm after doping and annealing. SEM investigations of these films show extremely fine nanostructures and demonstrated excellent adhesion, after Bi-doping, the nanostructures remained identical with a little change. UV/Visible studies were made in the range of wavelength (300-1100) nm to calculate the optical constants for these films. These measurements revealed a high value of the absorption coefficient and decrease the optical energy gap values from (1.85 -1.6) eV after doping with 3% Bi. The characterization of these films it can be chosen in the application of solar cells. On the other hand, the optical properties of SnS films have been enhanced by Bi-doping.

The ligand was synthesized from the reaction of pyridoxal hydrochloride with 2-amino-4-nitrophenol in ethanol (as a solvent) at a mole ratio of 1:1 and thoroughly mixed and refluxed for 6-8 hrs . The reaction was monitored using TLC (Ethylactate/hexane 1:1). The structures of the ligand and the complexes were characterised using spectroscopic techniques such as (FT-IR, 1HNMR, 13CNMR, UV-Vis, and Mass spectroscopy). In addition, molar conductance, magnetic susceptibility, elemental analysis, and thermo gravimetric, melting points were also measured for complexes. The antibacterial activities of the obtained products were tested against G- bacteria (Klebsiella pneumoniae and pseudomonas), G+ bacteria (Staphylococcus aureus and Bacillus subtilis). In addition, antifungal action was tested against (Candida albicans). The results were good in both tests.

When theReynolds number is low and the wavelength is long, math formulas are used to describe the streamfunction, as well as the gradient of pressure, temperature, pressure rise and axial velocity perwavelength, which have been calculated analytically. The many parameters in the current modelare assigned a definite set of values. It has been noticed that both the pressure rise and the pressuregradient decrease with the rise of the rotation and couple stress, while they increase with anincrease in viscosity and Hartmann number. The explanation of parameters is shown graphicallyby a series of figures using "MATHEMATICA".
