In terms of generating fuels, either solid or liquid. To mitigate human climate change, biofuels can replace fossil fuels. Emissions of greenhouse gases. Yet, evidence that biofuels are generated in a sustainable manner should be the foundation for any policy decisions about them. To this goal, life cycle assessment (LCA) offers details on the environmental effects linked to the manufacturing of biofuels. Here, we examine developments in biomass conversion to biofuels and their effects on the environment. through life cycle analysis. Gasification, combustion, pyrolysis, enzymatic hydrolysis pathways, and fermentation are examples of processes. Gasification, combustion, and pyrolysis are examples of low temperature thermochemical processes, which occur below 300 °C, and high temperature processes, which occur above 300 °C. In contrast to gasification, which operates at temperatures between 800 and 1300 °C, pyrolysis operates at a relatively lower temperature of up to 500 °C. We concentrate on the following topics: 1) the benefits and drawbacks of the thermochemical and biochemical conversion routes of biomass into various fuels, as well as the possibility of integrating these routes for better process efficiency; 2) methodological approaches and key findings from&nbsp; studies on biomass to biofuel conversion pathways published from ; and 3) social, economic, and environmental trends and knowledge gaps in biomass conversion into biofuels using thermochemical and biochemical methods.

Despite its contribution to lessening the demand for medical services, it carries a number of health concerns for individuals who use it. Research on this subject revealed that students in the health sciences continued to self-medicate and advocate for it in public. Accordingly, the aim of this study was to estimate the prevalence of self-medication and investigate factors associated with it. A cross-sectional, questionnaire-based study was carried out to identify self-medication among undergraduate students at the College of Medical Technology, Derna, Libya. The data were collected and analyzed for counts and percentages. The study revealed that 64.72% of students reported self-medication practices in the preceding year. Moreover, self-medication practice was found more frequently in female students as compared to male students. Headache was the most frequently reported illness; commonly used drugs were antipyretics and analgesics; and the reason quoted was the disease's ease of prevention and cure. This study shows that self-medication is widely practiced among college students.

When welding austenitic stainless steel, the weld seam is exposed to heat and air, which causes oxidation.&nbsp; Purging is an important step to obtain high quality and prevent oxidation and thus avoiding discoloration and welding under bead discontinuities. The right purging gas is essential for getting the best results. The purpose of this study is to determine how different purging gases, such as pure nitrogen, pure argon, and a mixture of 26% N2, 4% Co2, and 70% He, affect the mechanical properties of 304 L austenitic stainless steel welds, including their tensile strength, yield strength, and hardness.

By crisp, we mean that the answer is either yes or no, not more or less. In traditional dual logic, for example, a statement can either be true or false but not both. In set theory, an element either belongs to a set or it doesn't. In optimization, a solution is either possible or it isn't. Precision means that the parameters of a model exactly represent either how we see the phenomenon being modeled or how the real system being modeled works.

The Reghaya sub-basin is located in the High Atlas of Marrakech; it covers an area of 306 km2 and is considered one of the most important sub-basins of the Oued Tensift. Although the watershed is receiving rainfall and snowfall at high altitudes, the study basin is experiencing very frequent hydrological disturbances. In this sense, we have chosen to study the flows recorded by the Tahanaout hydrometric station, located downstream of the watershed, to extract the hydrological cycles (low and high water) using the determination of the monthly flow coefficient. The hydrometric study of the Oued Reghaya watershed, shows that the flows recorded by the station of Tahanaout have a significant temporal variation. Generally, low water periods are marked in the summer and autumn months, whereas high water periods are marked in the winter and spring months. This work shows that the hydrological regime of the Oued Reghaya watershed is rainy, which makes it vulnerable to events</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-05-06T00:00:00+00:00 Copyright (c) 2023 Comparison Between Ultrasound Imaging and Mammogram Based on the Influence of Filter Materials on the Quality of Digital X Mammography 2023-05-08T02:02:51+00:00 Fathya Shabek <p>Diagnosis of cancer with the regular mammogram may be unreliable in nevertheless many cases since this mammogram may be unable to detect early tumors in many mammary glands. Digital mammogram is a modern technique that attempts to increase the accuracy of tumor detection. It can also be added to the magnetic resonance imaging. The digital mammogram can depict tumors in the mammary glands, which involve injection of intravenous dye while the patient is photographed with a series of mammography images that shows the flow of dye over time. It is based on the principle that fast-growing tumor’s need to increase the supply of blood to support their growth. The formula accumulates in such regions, so the digital mammogram provides therefore, a method of imaging based on the distribution of dye in the breast tissue, but it is still a two-dimensional technique. Although breast magnetic resonance imaging (MRI) may be used as an additional method to digital mammography in patients with high density mammary glands or non- homogenous tissue with ultrasound waves or both, and preoperative screening for women with breast cancer, it looks like the routine use of breast magnetic resonance imaging is unnecessary.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-05-08T00:00:00+00:00 Copyright (c) 2023 A Review of the Possibility Integrating the Solar System into the Libyan Railway Transportation 2023-05-12T13:58:43+00:00 Ibrahim Imbayah Abdussalam Ali Ahmed Abdulgader Alsharif Mohamed Mohamed Khaleel Ahmed Alarga <p>This study of the possibility of integrating clean energy into the Libyan railway transport system using the integration of photovoltaic cells provides the potential for electric power, whether in the development of transit trade or the production of renewable electric energy near the points of electricity consumption. In Libya, for example, by integrating photovoltaic cells at stations, up to 100% of the electricity demand at railway stations can be covered, and the surplus will support the public electricity grid. Political support (for buildings in integrated photovoltaic plants) BSIPV will contribute to the development of transit trade in Libya. This study suggests the exploitation of solar systems in the railway transport system and the distribution of renewable energy sources along the railway lines in Libya, which is a link between Africa and Europe. And I will propose innovative ideas that achieve integration between railway transportation and solar energy.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-05-12T00:00:00+00:00 Copyright (c) 2023 Evaluation of the Muscles Pain Post General Anesthesia for Patients Who Inductions Succemethenium 2023-05-23T03:12:17+00:00 Khalid Salih Omar Almismary Najah Ahmeda Ibrahim Husayn <p>The aim is to Evaluation the Muscle Pain post general anesthesia for patients who induction succemethenium, Material, and Methods: The design of the study is descriptive, using a convenience sample of twenty diabetic patients (20) who were going to Operation Theater.&nbsp; Patients included in this study have the following criteria: 1. Be alert and be able to communicate verbally. 2. They are induction suxamethonium, Result: surgery, (27.8%) of patients went to the O.T. for cesarean section and cholecystectomy, respectively. Hysterectomy and laparotomy had the same percentage (11.1%). Just three patients went to the O.T. for an appendectomy. In relation to the duration of surgery, exactly one-half of the studied sample took two hours to finish the surgery, while just two patients consumed one hour, on the other hand, more than one-tenth of eighteen patients needed three hours to finish the surgery. Two-thirds (61.1%) of patients were administered ketamine as induction, and a majority (1889.9%) of patients were administered thiopental. While the majority (88.9%) of all the studied patients were administered the protocol.&nbsp; All patients were administered N2O and muscle relaxants as maintenance; one-half (50.0%) of patients were given ISO. of temperature; 72% of patients had a normal temperature at the first hour of surgery, and at the end of the second hour, the temperature was falling between 34 and 36 c. In the third hour, the percentage is still as in the second hour, Conclusion is that sincere efforts are required to find the efficacy of a technique that could significantly reduce the undesirable side effects of succinylcholine in order to curtail the valuable hospital costs being spent on the health of the patients in our poor country.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-05-23T00:00:00+00:00 Copyright (c) 2023 Optimization of PID Parameters Based on Genetic Algorithm Optimization for Ball and Beam System 2023-05-23T07:21:07+00:00 Ahseen Naser Aldeeb Abdulgani Albagul Abdussalam Ali Ahmed Rajab Algheetah <p>This paper applies Genetics Algorithms (GA) for tuning PID controller of ball and beam system. PID controller is used to control the output position of the system. A process model of the ball and beam system is defined based on its mathematical model. Using this model, an offline PID parameters optimization based on GA is done. The chromosome in GA represents PID parameters namely proportional gain (Kp), integral gain (Ki), and derivative gain (Kd). The objective functions are settling time and overshoot. The experimental results show that the step response of this GA-based PID controller has superior performance than it using PSO and trial and error.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-05-23T00:00:00+00:00 Copyright (c) 2023 A Field Study to Evaluate the Efficacy of Changing the Type of Anthelmintic on Nematodes in Sheep in the Western Area of Libya 2023-05-27T13:56:37+00:00 Asem Ramadan Amar Mohamed Abdulwahid Mohammed Almahdi Sirtiyah <p>The present experimental work was carried out at the Research Laboratory belonging to the Faculty of Veterinary Medicine and Agriculture, University of Zawia, on Mars in 2023.
