The body chemical composition in aquatic organisms is related to nutrition, habitat, age and sex. On the other hand, knowing the amount of chemical compositions helps to select the appropriate species for human nutrition and food industry. In this study, the change in chemical composition of common carp in different weights was investigated. For this purpose, 25 two-year-old carp were studied during the second year of rearing from different weight groups from 500 g to 1600 g. Protein, fat, ash and dry matter content of fish meat were measured. The results showed that the mean protein content of carp was 10.209 ± 2.106 %, fat was 9.429 ± 0.937%, ash 1.407 ± 198 % and dry matter 21.13 ± 1.62%, respectively. In addition, the results of this study indicate that there is no significant difference between chemical compositions of carp in different weights (P> 0.05). The results of the present study show that there is no relationship between chemical compositions (protein, fat, ash, dry matter) and the weight of common carp and the weight of fish has no effect on the chemical compositions. Therefore, there is no difference in common carp meat chemical compositions in different weights.

Aims: Women aged 40-52 years who use contraception are highly motivated to prevent pregnancy. In this age group, women are beginning to transition into menopause, which is the phase marked by the cessation of menstruation and the end of reproductive function. Menopausal women no longer need contraception to prevent pregnancy. This study aimed to assess the impact of educational interventions on contraceptive discontinuation among menopausal women.
Instrument & Methods: This research utilized a quantitative approach with a pre-experimental research design employing a one-group pre-post-test design and purposive sampling of 112 women. Data collection involved questionnaire completion and testing using the Wilcoxon Signed Rank Test with a significance level set at p<0.05.
Findings: The pre- and post-test analysis revealed significant changes in knowledge (p<0.001) and contraceptive discontinuation among respondents. The results of the pre- and post-test analyses revealed a substantial improvement in respondents’ characteristics concerning knowledge about menopause. There was a significant rise in the average score from the pre-test to the post-test across all aspects examined, including understanding, signs and symptoms, and the impact of menopause. Utilizing the Wilcoxon Signed Rank test, the disparity in pre-test and post-test scores on the sub-variables of understanding, signs and symptoms, and management of menopause was statistically significant (p<0.05).
Conclusion: Implementing health education models for menopausal women is effective in enhancing knowledge and promoting independent decision-making regarding contraception cessation upon the detection of menopause.

Aims: This study aims to analyze the effect of implementing health education technology in improving nutritional literacy and preventing anemia in pregnant women, as well as identifying the most effective technological approaches to support maternal and fetal health.
Instrument & Methods: A cross-sectional quantitative study was conducted at Balerejo Health Center, Madiun Regency, involving 132 pregnant women as samples. Data were collected through questionnaires (Likert scale), in-depth interviews, and medical records. Statistical analysis used Smart-PLS to test the reliability of the instrument (Cronbach's Alpha >0.6) and the relationship between variables (PLS regression). Four technological interventions were evaluated: mobile applications, e-learning, social media, and telemedicine.
Findings: All technologies have a significant effect on improving nutritional literacy and preventing anemia. Telemedicine has the largest effect (T-statistic = 2.861; p-value = 0.004) due to direct interaction with health workers. The R² value is close to 1.000 indicating that the technology variable explains most of the variation in the results. Although 84.1% of respondents are of ideal age (20–35 years) and 59.1% have adequate income, 40.9% of pregnant women still experience anemia, emphasizing the importance of nutritional education.
Conclusion: Implementation of health education technology, especially telemedicine, is effective in increasing nutritional literacy and reducing the risk of anemia in pregnant women. Recommendations include strengthening digital infrastructure in remote areas, digital literacy training, and monitoring evidence-based content. These findings support the development of sustainable technology-based maternal health policies.

The satellites on the ground during construction and transportation, in launching stage and operation in space are under various types of dynamic loads, including high and low frequency vibrational loads, acoustics, shock, impact, etc., each of which can be an important source in the creation of stress on the satellite. The satellite components should be designed in such a way that can continue to operate while facing these situations. Electronic boards, in particular their solder joints, are critical components of satellites. Therefore, investigation of damage in design process of boards have great importance. Loading pattern on the satellite during its operation is usually random which considered as quasi-static load. Improvement of the design of the satellite against the weaknesses shown while facing different loads is essential, and given the fact that it is time consuming and costly to carry out laboratory tests, the use of analytical methods for checking the strength and lifetime of the structure can be very useful. In this research, random vibrations environment is equivalent to pseudo-static loads, and using the multilayer plate theory, the stresses in solder joints and failure of joints under this loading will be investigated. Also, the effect of parameters such as electronic board width and the boundary condition of the printed circuit board on the solder joints' stress will be considered in analytical solution.

 Malt beverage is one of the most popular drinks in the world. Recently, consumption of non-alcoholic beverages has expanded significantly in many countries. The permitted level of alcohol in malt beverage is less than 0.5% by Iranian National Standards. In this study, a method was developed to determine ethanol content in malt beverages by FTIR, equipped with Horizontal Attenuated Total Reflectance (H-ATR). Here, the Limit Of Detection (LOD) and Limit Of Quantification (LOQ) were 0.07% and 0.23%, respectively. The correlation coefficient of calibration curve was higher than 0.999. Fifty commercial malt beverages from six brands (five Iranian and one imported brand) and three types of flavored malt beverage (classic, equatorial, and lemon) were assessed. The average detected ethanol amount in samples was 0.19%, varying between 0.00-1.47percent. The results showed that the amount of ethanol in lemon malt drinks was more than the maximum permitted limit; that could be attributed to the usage of ethylene glycol for extraction of lemon flavor.

Feelings of spiritual hollowness and fading away spirituality are characteristics of the present century. Also, the emergence of false spiritual schools has led to the collapse of spiritual life. Since the innate needs of man can be met only with true spirituality and obedience to the commands and prohibitions of the God almighty.  And by obeying those commands and prohibitions, spirituality takes root in human beings and the thirst of human nature will be quenched by the refreshing spirituality hence, taking care of spiritual life is one of the essential anthropological necessities of human beings. The purpose of this research is to analyze Imam Mohammad Ghazali's views on "spiritual life" and the study of the components of this life from his perspective. To achieve this goal, there is need to examine and explain the verses of Holy Qur'an and refer to the interpretations on the one hand and explaining Ghazali's approach in the books Al-Ehya Ulom al-din and Kimiya-e- Saadat. This is done by a descriptive method and the analysis Al-Ghazali's views in the form of documents. The result of research is aimed at: promoting the knowledge of God and institutionalizing duties of worship and creating motivation for the growth of genuine religious spirituality. Among the feasible successes is the allegiance to the prophetic tradition, repentance and return to glorious God, cultivating virtues and repelling vices and fighting vile desires.
