The main aim of this work is to introduce the analytical approximate solutions of the water wave problem for a fluid layer of finite depth in the presence of gravity. To achieve this aim, we begun with the derivation of the Korteweg-de Vries equations for solitons by using the method of multiple scale expansion. The proposed problem describes the behavior of the system for free surface between air and water in a nonlinear approach. To solve this problem, we use the well-known analytical method, namely, variational iteration method (VIM). The proposed method is based on the use of Lagrange multipliers for identification of optimal value of a parameter in a functional. The proposed method provides a sequence of functions which may converge to the exact solution of the proposed problem. Finally, we observe that the elevation of the water waves is in form of traveling solitary waves.

This study aims to investigate the effect of sodium replacement on the quality characteristics of past?rma. For this purpose, past?rma production with four different salt mixtures(Ⅰ. 100% Na Cl; Ⅱ. 50% Na Cl + 50% KCl; Ⅲ. 40% NaCl + 40% KCl + 20% CaCl2; Ⅳ. 30% NaCl + 40% KCl + 20% CaCl2+ 10% MgCl2) were carried out using traditional method. The use of different salt mixtures for past?rma had no statistically significant effect on the microbial counts and residual nitrite of the final product. The a* and b* values were affected by this treatment. The salt mixture containing CaCl2or CaCl2+ MgCl2significantly decreased the p H values and sensory scores. The eighteen volatile compounds were affected by the salt mixtures. Na~+, K~+, Ca2+, and Mg2+had a certain increase depending on their ratio in the salt mixtures. The highest Cathepsin activity in all past?rma samples was observed in Cathepsin B + L. The salt mixture with NaCl + KCl + CaCl2+ Mg Cl2increased acid lipase activity. However, this mixture had no significant effect on neutral lipase activity.

Background:After promising initial results from the administration of a third(booster)dose of the BNT162b2 messenger RNA vaccine(Pfizer-BioNTech)to persons 60 years of age or older,the booster campaign in Israel was gradually expanded to persons in younger age groups who had received a second dose at least 5 months ***:We extracted data for the period from July 30 to October 10,2021,from the Israel Ministry of Health database regarding 4,696,865 persons 16 years of age or older who had received two doses of BNT162b2 at least 5 months *** the primary analysis,we compared the rates of confirmed coronavirus disease 2019(Covid-19),severe illness,and death among those who had received a booster dose at least 12 days earlier(booster group)with the rates among those who had not received a booster(nonbooster group).In a secondary analysis,we compared the rates in the booster group with the rates among those who had received a booster 3 to 7 days earlier(early postbooster group).We used Poisson regression models to estimate rate ratios after adjusting for possible confounding factors.

In this study, we examine male blue gourami (Trichogaster trichopterus) nest-building behavior that is affected by other males and interactions under experimental conditions. Males found in the area control the territory and sexual behavior, and are influenced by the behavior of other males. The results of this study show that the sexual behavior (nest-building) of male blue gourami is affected both by the behavior and pheromones of other males. We suggest that males must defend their territories in order to prevent these two factors from interfering in nest-building.

The study aimed at examining by quantitative research design to what extent management style affects organizational climate of schools A, B, and C of Arab sector in Israel, while comparing a test group of school A to a control group of schools B＋C. The research question was： What is the impact of a principal＇s management style on creation of a positive school organizational climate？ Quantitative data collection was conducted by means of validated questionnaires from relevant scientific literature. The findings indicate that a principal has a central role in a teacher＇s perception of professional autonomy. The sense of professional autonomy of a teacher is reinforced the more a teacher senses that the principal is an educational figure or a leader whom he can consult with regarding personal and professional problems. Differences were found among teachers in perception of school characteristics as providing various levels of autonomy.

In this study, it has been investigated that the incorporation of poly(ethylene glycol) and 4-styrenesulfonic acid sodium salt into acrylamide hydrogel during free radical solution polymerization synthesis for novel highly swollen adsorbents and for the effective removal of some potential pollutants from aqueous solutions such as cationic dyes. Poly(ethylene glycol)diacrylate was used as a multifunctional crosslinker. The main purpose of this study was to combine both monomers and a polymer in a new polymeric system. Dye sorption properties of the polymeric hydrogels were investigated by using cationic dye such as Janus Green B. Swelling and sorption studies were carried out at 25°C. For structural characterization, FT-IR analysis and SEM studies were applied. To determine the sorption behaviors of Janus Green B, some sorption parameters such as dye removal capacity, adsorption percentage, and partition coefficient of the polymeric hydrogels were investigated.
