Desalination has become one of the main alternatives to compensate for water shortages. Although seawater desalination is expensive and has many environmental risks, it is still an important option to compensate for water shortages in Egypt. The discharge of liquid waste (especially heavy metals) from the station into the sea has a negative impact on the water, so the spatial distribution of heavy metals (lead, cadmium, and copper) shows high concentrations near the outlets of both AlQusayr and the port of Al-Qusayr. Hamata desalination plants in the southern Red Sea. As for higher quantities of heavy metals - higher than the standard values - such as (Cu, Pb, Cd), they are classified as seawater pollutants, whether they show evidence of toxicity or not. The study demonstrated that seaweed has bio-absorption properties and can effectively absorb heavy metals from the surrounding water, and thus it can serve as a bio-indicator in tools for monitoring the degree of pollution, as well as evaluating water desalination activities

The optimal design of heliostat field in solar power generation device is studied Heliostat field generates high temperature by focusing the sunlight reflected from the mirror surface, thus pushing the turbine to generate electricity. In order to improve the efficiency of power generation, this paper optimizes the parameters of heliostat field, establishes a singleobjective optimization model, and uses mixed strategy whale optimization algorithm to solve it. Through geometric optical analysis and ray tracing model, the optical efficiency of heliostat field and the annual average output thermal power per mirror area are calculated. Finally, through the discussion and analysis of the model, the optimization design method is evaluated.

Fish are a commonly available type of vertebrate that rely on both congenital and acquired immunity to protect against pathogens. Congenital immunity acts as their first line of defense, while acquired immunity is crucial in defending against specific pathogenic infections. Toll-like receptor (TLR) genes play a significant role in their innate immunity and are essential to their immune system. To better understand the evolutionary status of TLRs in fish and their adaptive immune defense characteristics, researchers analyzed ten fish species' TLR7 and TLR13 gene sequences using the NCBI and Ensembl databases

Covid-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which hit the world in December 2019 is one of the worst medical emergencies people have ever encountered. Human angiotensin I converting enzyme 2 (ACE2) is the entry path of this virus to the host that regulates the renin-angiotensin-aldosterone system (RAAS). Hypothesis: Susceptibility to SARS-CoV-2 infection may be affected by ACE rs4646994 and ACE2 rs2285666 polymorphisms.

Introduction: Tanzania aims for 95% of persons living with HIV (PLHIV) to know their serostatus by 2023. Methods: An uncontrolled before-after study design was conducted between March 2018 (pre-intervention phase) and July 2018 (post-intervention phase). A total of 183 participants (males=89; females=94) were recruited for this study. Data were collected at baseline and at the one-month and three-month follow-ups using a pre-and post-test semi-structured questionnaire. Descriptive data are presented using measures of central tendency and their respective measures of dispersion. No comparative statistical analysis was performed.

In doped calcium fluoride transparent conducting powder were prepared by solid-state reaction method. Structural properties of the samples were investigated as a function of various In-doping levels (x=0.00-0.01-0.02-0.03). The results of x-ray diffraction have shown that the samples are polycrystalline structure in cubic phase and show presence (111), (220), (311), (400) planes in pure CaF2 sample and the preferred orientation is (220) for pure CaF2 and we have peaks correspond (101), (112), (200), (202) for In for all samples and the preferred orientation is (112) for In for all samples. The average of crystallite size is within the range [2.976-0.845nm] for all samples. The relative intensities, distance between crystalline planes (d), crystallite size (D) and lattice parameters (a) were determined. Measuring the infrared spectrum of pure Calcium fluoride, it is found that there are six vibratory frequencies, namely: (3444.52 - 1517.59 - 1138.40 - 876.40 - 639.93 - 436.29) cm- 1 and six vibratory frequencies for indium doped calcium fluoride at 3wt%. (3441.94 - 1516.77 - 1138.44 - 876.55 - 642.09 -436.44) cm- 1 The study showed that the absorbance values, the absorption coefficient, the refractive index and the optical length were in the indium doped sample by 3wt% greater than that of the pure Calcium fluoride compound and are respectively: α=14.163 cm-1 n=1.767.

Increasing the nickel content in the layered LiNixCoyMnzO2 (x + y + z = 1), the most promising cathode materials for lithium ion batteries (LIBs), has been a dominant strategy to increase their energy density. In this study, we report the control on the primary particle morphology of precursors with different nickel contents, e.g. Ni0.5Co0.2Mn0.3(OH)2 Ni0.6Co0.2Mn0.2(OH)2 and Ni0.8Co0.1Mn0.1(OH)2 by adjusting the preparation process. The scanning electron microscopy (SEM) images demonstrate that by decreasing the pH value and increasing the ammonia concentration, the order of precursors with different nickel contents increases, resulting in gradually directional and orderly stack or interlaced arrangement in the primary particles. With the increase of nickel content, the precursor changes from nano-sheet stacking like plug-in stereoscopic spheres to nano-needle interweaving like wool balls, all of which tend to grow in the direction of [001].

Penicillin and streptomycin are the most commonly used to prevent bacterial infection or contamination in cell culture. However, the role of Penicillin-streptomycin on inducing mouse embryonic stem cells(mESCs) to differentiate into cardiomyocytes is unclear. To illustrate the mechanism of penicillin-streptomycin on inducing mESCs differentiation into cardiomyocytes, we firstly investigated mESCs differentiation into cardiomyocytes by the traditional method. The time- space expressions of cardiac-specific genes were detected by real-time PCR and western blotting at 8 different time-points over a period of 36 days. Furthermore, action potentials were measured by patch clamp for mESC-derived cardiomyocytes. Embryonic bodies through hanging drop method, were incubated with penicillin-streptomycin (P/S) at different concentrations (1×PBS, 1×, 2×, 5×), and then, the number of cardiomyocytes and expression levels of myocardial marker proteins were detected by flow cytometry, cellular immunofluorescence, and western blotting, respectively. We found that the SSEA-1 of mESC presented green fluorescence, and H.E. staining showed karyoplasmic ratio >>1. Besides, TNNI3, TNNT2, ACTN2 and MYL-2v were clearly visible by cellular immunofluorescence. Furthermore, the ACTN2 positive cells rate of 2× and 5× groups were remarkably higher than that in Cntl (1×PBS) group and 1× group (10 Units/mL penicillin; 10 μg/mL streptomycin), as well as the expressions of GATA4, MYL-2v, TNNI3, ACTN2
