The main aim of this paper is the hydrochemical evaluation of groundwater and Its impact on the quality of groundwater resources in order to check its suitability for drinking and irrigation In Alut area located in northwestern Iran. Geologically, metamorphism rocks are present in most parts of the Alut area for example Gneiss, Green schist, sericite schist, slate and metaryholite. In order to evaluation of groundwater quality and hydrochemical assesment, samples were taken from 50 wells and springs in the study area and the amount of heavy metals as well as its various parameters were measured. In the studied area, the groundwater facies belong to the calcic bicarbonate type and generally hard water due to the total hardness. In terms of EC and sodium adsorption ratio (SAR), Na% and residual sodium carbonate (RSC), the groundwater is totally suitable for irrigation. Moreover, dissolved heavy elements concentrations in the groundwater of the Alut area have the safe limits which recommended by the WHO. Based on the ionic ratios, Gibbs diagram, saturation index and multivariate analysis indicate that silicate sources had a relatively large impact on water chemistry in the Alut area. These calculations also showed that the groundwater source in the Alut area generally originated from weathering and interactions between silicate water and rock. Based on these studies, ground waters in Alut area are suitable for drinking, irrigation and agriculture and are chemically of a calcium bicarbonate type, and hard. Statistical studies show similar results between factor analysis and cluster analysis.

The main aim of this study was to determine the effect of sodium bicarbonate and beta-alanine supplementation on anaerobic capacity and blood lactate levels of female futsal players. Method: 40 volunteer female futsal players of the Tehran League were selected based on the variables of entering the research and sampling and randomly selected four of the 40 volunteers and randomly divided into four control groups (n=10), sodium bicarbonate (n=10), beta-alanine (n=10) and sodium bicarbonate and beta-alanine (n=10) were divided. The anthropometric characteristics of their height, weight and body mass index were measured before the test. Then the Wingate test was performed to measure power and their blood lactate level was also measured using a lactometer. After each test session, the bicarbonate group received 0.3 grams of sodium bicarbonate supplement per kilogram of body weight, the beta-alanine group received 0.3 grams of beta-alanine supplement per kilogram of body weight, and the combined group also received per kilogram The combination of beta-alanine and sodium bicarbonate was used for 0.3 grams of body weight, and the control group used 0.3 grams of placebo (starch) per kilogram of body weight, and after 90 minutes, the relevant tests were performed again. Also, the subjects' diet was controlled during the test. Finally, descriptive statistics, Shapiro-Wilk test, one-way analysis of variance test and Tukey's post hoc test were used for statistical analysis of the data using spss/21 software at a significance level of p≤0.05. The results showed that the supplement of sodium bicarbonate and beta-alanine has a significant effect on the average power and blood lactate level of female futsal players. According to the results of the research, it is suggested that coaches and players use sodium bicarbonate and beta-alanine supplements to increase strength and reduce the negative effects of lactic acid.

استفاده از تفاله پرس شده آرگانیا اسپینوسا برای تغذیه دامهای اهلی به دلیل وجود ساپونینها محدود شده است، که طعم آن را برای دامها بسیار تلخ و بد مزه میسازد. پژوهش حاضر با هدف ارزیابی یک روش سمزدایی کاهش دهنده سطوح ساپونین تفاله پرس شده و چگونگی تأثیر آن بر محتوای مواد مغذی انجام شد. روششناسی پاسخ سطحی استفاده شده در این پژوهش شامل کوبیدن تفاله پرس شده آرگان و در معرض خیساندن و جوشاندن آن در 3 واسطه: آب مقطر، محلول سدیم بیکربنات در غلظتهای متفاوت (02/0، 01/1 و 2 درصد)، و محلول اسید سیتریک در غلظتهای متفاوت (10/0، 05/1 و 2 درصد) بود؛ نسبتهای مربوطه از تفاله پرس شده آرگان برای خیساندن و جوشاندن در نسبتهای 1:5، 5/12: 1 و 1:20 (w/v، g/mL) فیکس شدند؛ زمانهای انتخاب شده نسبتهای مربوطه 1، 24 و 48 ساعت بودند؛ دماهای جوشاندن انتخاب شده به ترتیب 40، 80 و 120 درجه سلسیوس بودند؛ و زمانهای جوشاندن به ترتیب، 10، 25 و 40 دقیقه بودند. آزمایشات نشان دادند که خیساندن در واسطههای اسیدی و بازی به طور مؤثرتری ساپونین را با میانگینهای 93 و 86 درصد به ترتیب، نسبت به خیساندن در آب مقطر را کاهش میدهد (30 درصد)، اگرچه ما کاهشهای متوسط معنیداری در میان محلولهای جوشاندن مشاهده کردیم. محتوای تغذیهای تفاله پرس شده آرگان تیمار شده با تیمارهای متفاوت نسبت به غیر تیمار شدهها کمتر کاهش پیدا کرد، پروتئین خام تفاله پرس شده آرگان غیر سمزدایی شده در مقایسه با سمزدایی شده که دامنهای بین 40 تا 47 درصد داشت 48 درصد بود. بنابراین، کاهش سطوح ساپونین، تفاله پرس شده آرگان را برای دامها اشتها آورتر خواهد ساخت و ممکن است سوء تغذیه پروتئینی، یک مشکل بزرگ تغذیه حیوانی در مراکش را کاهش دهد.
