This study aims to evaluate the risk of using untreated wastewater for vegetable contamination. Water samples and vegetables cress and scientific name ( Lepidium sativum ) were collected from farms using wastewater and well water for irrigation for three seasons (Autumn, Winter, and Spring). Results show that untreated wastewater is characterized by an alkaline side of neutrality and has a high content of the Biochemical Oxygen Demand BOD 5 value of 124 mg. l -1 . The Biochemical Oxygen Demand (BOD 5 ) values variations coincided with water temperature variations and no Dissolved Oxygen (DO) detection during the study periods. Cryptosporidium spp. and other intestinal parasites were observed in wastewater in nearly all studied seasons. Wastewater-contaminated vegetables irrigated by it. Well, water is characterized by the highest EC value of 1119 µS.cm -1 during Winter and the highest pH value of 8.1 during the Spring season. Generally, well water is contaminated with parasitic organisms. Cryptosporidium spp. was detected in well water but no detection was found in cress irrigated by it.

Electrostatic lenses are established using billed electrodes with cylinder bores which are exactly organized on a line of symmetry. In this paper, four designs of three-element cylindrical electrostatic lenses in the acceleration and deceleration mode with different geometrical shapes were created to prove how the operational characteristics of the lenses are affected by the electrode geometry according to potentials, the electron beam diameter in the image plane, kinetic energy, velocity, and acceleration before and after the electron beam passes through each of the four lenses. The best lens is chosen from the four lenses based on its optical performance. It has been found that the lens with the concave outer electrode surface has the best optical performance as an accelerating lens, and the lens with the concave inner electrode surface has the best optical performance as a decelerating lens. It was discovered that the geometry of the electrodes plays a major role in minimizing the beam electron diameter at the image plane and in accelerating and decelerating the electron beam. The calculations are carried out by using the SIMION8.0 and SL Tools Programs package.

With the simultaneous thermal spraying of glassy arsenic selenide (As 2 Se 3 ), a significant influence of the introduced Indium (In) and Selenium (Se) on the films' structural and photovoltaic properties was established. The glassy As 2 Se 3 and In or Se were deposited simultaneously at up to 60 nm/s on cooled substrates at different temperatures ranging from 70 to -50 °C, layers with a thickness of 0.5 to 1 m in a vacuum 10-3 Pa. Films produced on low-temperature substrates result in structural modifications that can be utilized for lithography and electrically active defects. The energy necessary for the As 2 Se 3 annealing technique, according to the results, is equal to 0.57 eV of high-temperature energy. When Se is supplied at a temperature of -50 °C, we saw that the photocurrent increases at low temperatures. The image is minimally affected by Se increases greater than 7%. The solubility time of the non-irradiated segment is 5 seconds, the rest layer dissolves in 12 seconds, and the thickness of the rest layer is above 75%.
通过同时热喷涂玻璃化硒化砷(As 2 Se 3)，确定了引入铟(In)和硒(Se)对薄膜结构和光伏性能的显著影响。在10-3 Pa的真空条件下，在70 ~ -50°C的不同温度下，以高达60 nm/s的速度同时沉积了As 2 Se 3和In或Se，层厚为0.5 ~ 1 m。在低温衬底上生产的薄膜导致结构修改，可用于光刻和电活性缺陷。结果表明，as2se3退火技术所需的能量为0.57 eV的高温能量。当Se在-50°C的温度下供电时，我们看到光电流在低温时增加。Se增加大于7%对图像影响最小。未辐照段溶解度时间为5秒，休息层溶解度为12秒，休息层厚度在75%以上。

The current study included the determination of the Heat Production Rate (HPR) resulting from the decay of radioactive elements ( 238 U, 232 Th, and 40 k) after determining their concentrations using the technique of collecting gamma ray’s spectrum by means of the sodium iodide detector NaI (TI). The importance of determining the heat production rate, because it has a profound effect on the surface of the earth’s crust, especially in the conditions of desertification that have swept the globe in the last two decades. To achieve the objective of the study, 30 samples of natural water were collected. These samples varied between rainwater, dams, groundwater and pure tap water to natural spring water. The results showed that the concentrations of uranium ( 238 U) ranged between 0.161-0.006 ppm and thorium ( 232 Th) concentrations between (0.462-0.110 ppm), in addition to the potassium ( 40 k) concentration between (0.23-0.023%). These values showed radioactivity levels below the safe and standard limits set by the UNSCEAR Committee. While the results showed for the heat production rate values ranged between (0.0223-0.0091), which indicates a low heat production rate that does not affect the temperature of the earth's crust within the limits of the sample sites that this study included. The results of the current study can be used to provide basic data for future epidemiological investigations and monitoring programs. In the areas under study

An important use of active inductor feedback is reported. It was evident that a frequency dependent impedance of an active inductor is similar to that of an ordinary spiral inductor which is a key advantage in integrated circuit design given the fact that Mosfet-based active inductor circuit occupies less volume on board a chip. In this work, a 42 dBΩ transimpedance (TIA) gain at 1 GHz is obtained with 33 𝑝𝐴 ⁄√ 𝐻𝑧 of input referred noise with a very low power consumption of 0.605 mW. The Common-Gate Common-Source input stage with an active inductor feedback is reported in this work for the first-time long side a second stage current mirror with additional local active inductor feedback. The extremely low level of power consumption is considered to be another key advantage for that matter despite the moderate levels of TIA gain, bandwidth and input-referred noise current spectral density with 1V DC supply voltage. The LTspice software was used for simulation.

Heavy-ion fusion reactions are important and essential to express the dynamical properties of colliding nuclei, and to address the tunneling effect in quantum mechanics. In the fusion process, the ion-ion potential plays an important role in approaching the measured cross section with the experimental value by influencing the tunneling probability of interacting nuclei. In this work, the fusion cross-sections of closed-shell heavy-ion fusion systems have been calculated and analyzed in the framework of coupled channel theory, using the code CCFULL, by fixing the potential depth value = 102.9 MeV and the fusion radius = 1.096 , while, the diffuseness parameter of Wood--Saxon potential is varied from 0.6 to 1.1 to fitting the fusion cross-section data at energies near and below the Coulomb barrier. It was observed that our approach is able to estimating the experimentally observed cross-sections of closed-shell colliding nuclei.
