It is known that morphological and anatomical analysis is an important method for identifying medicinal plant materials (MPR). To date, not all types of pharmacopoeial plants have an optimal description of microscopic diagnostic signs. This article presents the study of the morpho-anatomical structure of the vegetative and generative organs of the medicinal, alkaloid and essential oil plant Haplophyllum perforatum, growing in the conditions of Uzbekistan, and identifies characteristic diagnostic signs, and also determines the localization of biologically active substances. The revealed features are species-specific diagnostic signs and can be used as additional diagnostic signs for the identification of species and plant materials

The aim of this study was to determine the appropriate dosage of NPK fertilizer (16-16-8) for the growth of Dunaliella sp. Two separate experiments were conducted in a controlled temperature (24 ± 2.0 °C) room. Microalgae were inoculated in 8 L jars at 25‰, and initial cell density was inoculated at 1 × 106 cells/mL. In the first experiment, NPK (N:P ratio of 1:1) was added to microalgae culture medium, with N concentrations of 8, 16, and 24 mg/L. The results showed that the highest cell density was obtained with 4.7 × 106 cells/mL on day 11 with the 16 mg/L treatment. In the second study, microalgae were cultured with different ratios of N:P—from 1:1 to 15:1—in which the final N concentration in the culture medium was 16 mg/L. The results showed that the cell density was highest at 5.72 × 106 cells/mL in the N:P treatment ratio of 9:1 on day 9, and the dry weight of biomass reached 0.15 g/L on day 7. Overall, the results of this study indicated that NPK can be used to culture Dunaliella sp., but it is necessary to adjust the N:P ratio to 9:1 in order to obtain the highest growth of the cell population

This study aims to observe the reproductive biology of Coilia rebentischii distributed from downstream of the Hau River (one of the branches of the Mekong River) to the estuary of Dinh an and Tran De, in order to supplement the existing scientific data and to serve as a basis for research on artificial reproduction. The study was conducted from July 2019 to June 2020 by collecting fish samples in three sites from downstream of the Hau River and the estuary of Dinh an and Tran De. Results showed that the gonadosomatic index (GSI) of C. rebentischii ranged from 1.10% to 6.92%, which was greater than the fluctuation in the hepatosomatic index (HSI) (from 0.21% to 1.20%); the conditional factor (CF) of the fish also displayed less fluctuation, with the CF reaching its highest value in November. Fecundity of fish ranged from 218–943 eggs/g (mean=495 eggs/g), with a total length of 10.4 cm and total weight of 16.01 g. The maturity size of female C. rebentischii was 11.05 cm, while that of males was 13.69 cm. Result was recorded that breeding season of C. rebentischii starts from January to December, in which the highest breeding is from June to November

The scarcity of resources, instability of staff, high turnover of skills (15%), retention of health professionals are all factors that affect the performance of the public service in hospitals in the Laâyoune region. In this context, this study has reflected on the influence of public service motivation on work performance. To examine this relationship, the study identified the determinants of the Motivation for public service (MPS) as well as its correlation with human resources (HR) performance in the public sector in Laâyoune regional hospital. Objective: This study aims to measure public service motivation in Regional Hospital Center of Laayoun (CHRL). Methods: Based on a mixed correlational descriptive study, using a questionnaire, two measuring instruments, and interviews. The data collected by the quantitative tools were analyzed by SPSS17.0 software. For exploratory factor analyzes and EQS6 .1 for confirmatory factor analyses. Results: They reveal that there is no correlation between MPS and performance. However, there is a significant correlation between the MPS and a performance dimension (organizational confidence) among physicians of r = .46 (p <.05). Also, there was a significant correlation between MPS and the performance (job satisfaction) dimension of r = .26 (p <0.05) among nurses. As for the administrators, the results show that there is a significant correlation between the MSP and the performance component (the organizational climate) of r = .57 (p <.05). Conclusion: the correlation between public service motivation and work performance among healthcare professionals in hospitals is a reality in Laayoune. Determining the correlation between public service motivation and work performance at the national level is recommendable for improving the effectiveness of health professionals

The study was conducted to assess the application of Chlorella sp. and baker’s yeast Saccharomyces cerevisiae in feed rations and the frequency of water change in improving the population growth of the freshwater rotifer Brachionus calyciflorus. Rotifers were inoculated at 200 rotifers/mL in 10 L jars containing 8 L of disinfected freshwater. The results show that while the highest density of rotifers (655 rotifers/mL) was obtained in the combination of 75% algae + 25% of bread yeast, it was not significantly higher (p > 0.05) than the culture where rotifers were offered solely algae. The growth of the rotifer population was also improved by the frequency of water change per day, and the density reached 855 rotifers/mL, which was not significantly higher than that of water change every 2 days, but significantly higher than the culture where water change was not applied. These results confirmed that rotifers B. calyciflorus reached the highest density when fed 75% algae + 25% yeast with water change applied daily
