Effect of Different Protein Source on the Growth Performance and Body Composition of Seabream (Sparus aurata L.)

ABSTRACT Six experimental diets containing isonitrogenous (383 g kg -1 ) and isocaloric (18.4 kJ g -1 ) energy were formulated from fish meal (1), shrimp meal (2), soybean meal (3), fish and soybean meal (4), shrimp and soybean meal (5) and fish & shrimp meal (6). Results showed that no significant differences in FBW, DWG and SGR, were observed of fish fed diet contained sole source of fish meal protein and groups of fish fed diets contained 40 % FM and 20%SBM and group of fish fed on 30% FM and 27% SM. Also, had a significantly (P≤0.05) higher than the rest of experimental groups. Also, economical efficiency showed that the reduction of feed costs was easily observed for the feed costs per Kg weight gain which decreased with increasing incorporation levels of SBM. Therefore, it could be concluded that the SBM 20% can replace fishmeal protein in diets for sea bream fingerlings under similar experimental conditions

Investigating the Factors that Enhance Tourists’ Intention to Revisit Touristic Cities. A Case Study on Luxor and Aswan in Egypt

This article examines the impact of some factors that enhance tourists’ revisit intention to touristic cities. It adopts the TPB to predict tourists’ intention to revisit these destinations. An online the questionnaire was utilized to collect data from tourists that have earlier visited two touristic cities in Egypt which are Luxor and Aswan. The responses of 373 visitors to Luxor and Aswan were analyzed and the proposed hypotheses were evaluated using the Structural Equation Modeling (PLS-SEM). The results show that the model has a strong explanatory power to understand travelers’ revisit intention. Besides the TPB infrastructure, the added variables were found to exert a significant influence on the revisit intention. Specifically, the results show that: (1) e-WOM positively influences tourists’ attitudes and perceived behavioral control and subjective norms (2) tourist’s satisfaction positively influences tourists’ revisit intention and e-WOM (3) perceived behavioral control positively influences tourists’ revisit intention. The paper offers to the academic literature by implementing a framework that explains tourists’ intention to revisit the touristic cities. Also, it provides practitioners who are interested in tourism marketing with some guidelines to follow to enhance the revisit intention of tourists.

Combating the High Prevalence of Obesity among Egyptian Households: A Pilot Study: Port-Said Households/ مكافحة السمنة في المجتمع المصري: دراسة تجريبية في بورسعيد

Obesity is a major public health issue in Egypt and its repercussions are not only limited to the health dimension but also extend to affecting the productive capacity of the citizens. This adversely affects the overall fundamentals of the Egyptian economy. Moreover, there is a current political interest in promoting the health and well-being of the citizens which is reflected in the recent 100 Million Seha massive campaign that measured the weight and height of millions of Egyptians.By applying the decision-making rule which has to do adhere to the equity, administrative, and political criteria, we recommend adjusting the Egyptian subsidy system and making use of the medical centers. Solving tackling obesity requires intensive efforts at the level of the state, the regional community, and even the international level. Utilizing the current resources of the Ministry of Supply and Internal Trade is considerably convenient for controlling and preventing obesity in Egypt. The proposed recommendation, which is adjusting the Egyptian subsidy system, primarily depends on the role of the Ministry of Supply and Internal Trade in securing healthy food items in the ministries’ different distribution channels, along with providing healthier variants in the list of subsidized goods

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

A New Virtual Synchronous Generator Design Based on the SMES System for Frequency Stability of Low-Inertia Power Grids

In light of the challenges of integrating more renewable energy sources (RESs) into the utility grid, the virtual synchronous generator (VSG) will become an indispensable configuration of modern power systems. RESs are gradually replacing the conventional synchronous generators that are responsible for supplying the utility grid with the inertia damping properties, thus renewable power grids are more vulnerable to disruption than traditional power grids. Therefore, the VSG is presented to mimic the behavior of a real synchronous generator in the power grid through the virtual rotor concept (i.e., which emulates the properties of inertia and damping) and virtual primary and secondary controls (i.e., which emulate the conventional frequency control loops). However, inadequate imitation of the inertia power owing to the low and short-term power of the energy storage systems (ESSs) may cause system instability and fail dramatically. To overcome this issue, this paper proposes a VSG based on superconducting magnetic energy storage (SMES) technology to emulate the needed inertia power in a short time and thus stabilizing the system frequency at different disturbances. The proposed VSG based on SMES is applied to improve the frequency stability of a real hybrid power grid, Egyptian Power System (EPS), with high renewables penetration levels, nonlinearities, and uncertainties. The performance superiority of the proposed VSG-based SMES is validated by comparing it with the traditional VSG approach based on battery ESSs. The simulation results demonstrated that the proposed VSG based on the SMES system could significantly promote ultra-low-inertia renewable power systems for several contingencies

Obesity and sexual dysfunction in women

Background; Both overweight and obesity have been identified as risk factors for sexual dysfunction in men, but the relationship between sexual function and amount of body fat in females is still obscure. There are few reported studies in women assessing the relationship between female sexual function index (FSFI) and body weight. Objectives; To determine the sexual function of overweight and obese women. Subjects and methods; The study- included overweight and obese women were randomly chosen. Result; There was statistically significant relation between obesity and arousal, lubrication, orgasm and total FSFI score. Conclusion; Body mass index and obesity may affect sexual function in women. This effect can be seen in all sexual function parameters (libido, arousal, lubrication, satisfaction and orgasm) decreased with rising BMI, although definitive conclusions need to be studied further. Given that obesity can affect sexual function in a variety of its dimensions, and obesity and overweight are related to physical health, healthcare providers try to preserve physical health and improve sexual satisfaction by proposing BMI reduction, which is considered one of the most important factors in mental health so provide the basis for women’s health

An investigation of enzymatic kinetic resolution of racemic clopidogrel

This paper presents a biocatalysis based approach for asymmetric hydrolysis of Clopidogrel, one of the most effective antiplatelet aggregators. Instead of the conventional "wet lab" screening method, we used an advanced chemical information retrieval tool, Scifinder®, to find suitable enzyme candidate(s) for the asymmetric hydrolysis. Scifinder® search for reactions similar to the target reaction retrieved three potential hits: horse liver esterase, chymotrypsin and Candida rugosa lipase. Among the three, horse liver esterase was experimentally found to hydrolyse the correct isomer (R) of the racemic clopidogrel. Investigation of the effect of different water miscible co-solvents showed DMSO to provide the highest enantiomeric excess (ee) value of 20% at 43% conversion of the racemic ester, while a dicyanamide based ionic liquid as a co-solvent showed 12% ee. This article demonstrates the potential of the chemical databases as a possible rapid, resource-efficient tool to find an appropriate selective biocatalyst
