Third-Order Sandwich Results for Analytic Univalent Functions Involving a New Hadamard Product Operator
...Show More Authors

The objective of this paper is to examine the outcomes of third-order differential subordination and superordination for analytic functions within the region , specifically focusing on the utilization of the novel Hadamard operator . The results are derived by analyzing relevant categories of allowable functions. New findings have been found about differential subordination and superordination, along with the discovery of several sandwich theorems. Furthermore, other specific instances are also seen. The qualities and outcomes of differential subordination exhibit symmetry with the properties of differential superordination, leading to the formulation of the sandwich theorems.

Design, Synthesis, and Antimicrobial Activity Evaluation of New Developed Compounds via Introducing of 3, 4-Dimethyl Maleimidyl Sulfonamide Moiety
...Show More Authors

The present study focuses on creating and engineering novel compounds based on five established medications: Sulfamethoxazole, Ampicillin, Cefotaxime, Sulfamethazine, and Trimethoprim. The research involves incorporating a biologically active component, specifically the 3,4-dimethyl maleimidyl sulfonamide group, into these drug molecules to produce the target compounds. Many steps were performed on this target; the first one involved a reaction between 3,4-dimethyl maleic anhydride and aniline to produce compound (1) N-phenyl-3,4-dimethyl maleimide which reacts with chlorosulfonic acid in the second step producing compound (2) 4-[N-(3՝,4՝-dimethyl maleimidyl)phenyl sulfonyl chloride. The third step involved compound (2) reaction with t

Bias Reduction of Maximum Likelihood Estimation In Generalized Ramos-Louzada Distribution
...Show More Authors

The generalized Ramos-Louzada distribution (GRL) is a potential option for modeling the survival data which considers flexibility while modeling data with decreasing, increasing, reversed-J shaped, and J-shaped hazard rate functions. It should however be noted that the most widely used technique of parameter estimation of GLR is the maximum likelihood technique (MLE). While the MLE is quite efficient in large samples, they are known to be highly biased for small samples. We are therefore forced to come up with essentially nonbiased estimators for GRL parameters. Particularly, we investigate two procedures of bias correction: bootstrap and analytical methods in order to minimize MLE bias up to the second-degree. Two real-world data applic

Cholesterol and Glucose Lowering Effect by Some Edible Mushrooms
...Show More Authors

Ten species of edible mushrooms (higher fungi) were tested for their ability to reduce cholesterol and glucose in mice blood. The powders of dried fruit bodies of these mushrooms were mixed with standard mice diet at 5 and 10% (on dry wt.). This diet was also supplemented with 2% of pure cholesterol and glucose. Though the significant reduction of blood cholesterol and glucose in mice fed on all tested mushrooms (at both concentrations) was recorded, maximum reduction of blood cholesterol in mice fed on 10% of Pleurotas ostreanus (Gray types, Lentous edodes, Pleurotus ostreatus (White type), Ganoderma lucidum and Pleurotus sajor caju was 52.55, 50, 485, 46.6 and 18.1% in males, and 50,42, 48.72, 46.4, 41.4 and 38.1% in females, respectiv

Prediction of Deleterious Non-Synonymous Single Nucleotide Polymorphisms (Nssnps) of Human TLR7 Gene
...Show More Authors

      Toll-like receptors (TLRs) play a key role in innate immune response activation against viruses. TLR7, one of the TLRs family, is potentially important in controlling viral infection and the production of vaccines against the virus. The wide spectrum of discrepancy in response to antiviral drugs among different populations which is emerged by some pandemics like COVID-19 might be due to their different TLR7 single nucleotide polymorphisms (SNPs). The present study aimed to investigate the consequences of 401 non-synonymous missense SNPs (nsSNPs) within TLR7 on its protein structure, stability, and function by using specific bioinformatics tools. Seven bioinformatics tools were used to investigate 401

In this paper, a mathematical model consisting of the two harmful
phytoplankton interacting with a herbivorous zooplankton is proposed and studied.
The existence of all possible equilibrium points is carried out. The dynamical
behaviors of the model system around biologically feasible equilibrium points are
studied. Suitable Lyapunov functions are used to construct the basins of attractions
of those points. Conditions for which the proposed model persists are established.
The occurrence of local bifurcation and a Hopf bifurcation are investigated. Finally,
to confirm our obtained analytical results and specify the vital parameters, numerical
simulations are used for a hypothetical set of parameter values.

When it comes to changing one's profession after a several years of professional experience in a given field, It must be admitted that the person who adopts this approach is very persevering in the quest for self-realization. Thus, the search for improvement of the working environment and its conditions are often behind this type of choice. To try to understand this phenomenon of professional mobility, we conducted a study that concerning 1st cycle secondary school teachers who became guidance counselors and we focus on two parameters concerning this population: the causes that led them make this choice, and their socio-cultural characteristics (entry profiles).

Establishment of Causal Attribution as A Regulatory Strategy for Teaching and Learning
...Show More Authors

The theme of causal attribution has generated a great deal of work and focuses on the factors to which people attribute their behavior. However, its use to explain the results of the evaluation and the support for the regulation of teaching and learning acts has rarely been raised. Indeed, in the evaluation act, which is a privileged moment for reframing the learning process, teachers attribute the results obtained to the student himself, without worrying about the factors to which the student attribute itself these failures. This can distort the regulatory process and increase failure factors. The teacher's attributions of failure often relate to the results of the evaluations and are often explained by factors external to him: such as

Gel-biopolymers were prepared by different weights of two polymers (PVA, and PEG) dissolved with distilled water. Thick films of these polymers were prepared by using the casting method, with different thicknesses (t= 0.48, 0.34mm for PVA and t=0.58 mm for PEG). The objective of this research is to determine the viability of the organic polymer films of PEG and PVA on decomposition and the time required for their degradation  in the soil. The purpose is to use these polymers in industry without leaving plastic residues along with the possibility of their application as fertilizers for soil. The results showed that PEG film was degraded during the first week, while PVA film was changed in weight from 0.3 to 0.23 g and thickness from
