This study investigated the impact of working conditions in a cement factory on the health of 64 employees. Biochemical parameters (IgE, GPT, creatinine, CBC) were compared between workers and a control group of 10 individuals not exposed to factory emissions. A significant correlation between years of employment and elevated GPT levels was revealed by the findings, suggesting potential liver stress from prolonged exposure. Smoking was associated with higher creatinine levels, IgE levels, WBC counts, platelet counts, and neutrophil counts, indicating an increased risk of kidney impairment, allergic response, and inflammation. Age-related variations were also observed, with younger workers showing higher lymphocyte counts and older workers exhibiting higher creatinine levels,

Background: Obesity is still a main health problem in many countries. Obesity-related behaviors, such as low physical activity and unhealthy eating habits, tend to causes many problems, which highlights the need for early prevention from it. Objective: To explore the Interplay between obesity and healthy diet and exercise programs. As well to evaluate effect of 1 months of follow healthy life style on the status of GH and some biochemical parameters in obese subjects. Materials and methods: In this study, 40 individuals (20 obese and 20 non-obese male) from AL-Ramadi city during the period from April to May. Their age was 25-27 years old. Serum was taken to measure GH, and certain biochemical parameters and hormone, before and after applicate healthy diet and exercise program. Results: Serum the level of Insulin, FBG, HOMA-IR, TC, TG, LDL, BMI, weight and Fat showed significantly decrease, while there was significantly increase in GH, Vit D, HDL and protein, muscles after month from applicate the healthy diet and exercise program. Conclusion: In obesity, GH productions are reduced which are reversible with losing of weight, This is what was achieved through our results, therefore, growth hormone deficiency is considered a result of obesity and not a cause of it.

This study focuses on evaluating the validity of surface water and well water for the purpose of using it in the preparation of drilling fluid with bentonite clays of fatha formation taken from four sites for three Iraqi governorates are (Salah al-Din, Kirkuk and Ninevah), the selected sites from which water was Collected from (Upper Zab water, Lower Zab water, Tigris River water and well water), to conduct chemical and physical tests of water samples and indicate their suitability in using them as drilling fluid, and this analysis included properties Physical and chemical, which is the (pH) Total dissolved solid (TDS) and electrical conductivity (EC) and the Concentrations of Cations (Ca+, Na+, K+ and Mg+), and Anions (Cl-, HCO3-, SO4- and CO3-), and the results showed the suitability of water as a drilling fluid and rheological properties were tested (Rheological) for samples (density, viscosity, pH, Filtration and calcium ions). As well as adding some activated chemicals such as (XC-polymer, CMC L.V, Caustic Soda) to the drilling fluid and gave appropriate results according to the American Petroleum Institute (API).

An increasing interest in the use of solar energy to generate electricity for several applications has stimulated a need for studying optimal settings of photovoltaic panels. The photovoltaic panel performance is highly affected by its direction and its tilt angle. This research calculates the optimal tilt angles of photovoltaic panels for 60 locations in 60 countries around the world. These angles are calculated from vertical using Solar Irradiance Calculator. The optimal tilt angle for the studied locations ranges from (15°) to (57°) and (45°) to (87°) in winter and summer, respectively. It is shown that the angles that are obtained from equations are very close to those calculated from the calculator. This study is very useful to find the optimal tilt angle at any location by knowing only its latitude. The results can be extended to any location in the world. This research is intended to be used as a guidance for using photovoltaic panels

At This research used an electrochemical method to convert bulk silicon wafers into porous silicon (PS). The wafers, chosen with a (100) orientation and (8-3) Ω.cm resistivity, the time of etching was 25 min and the current density of etching 25 mA/cm². It was carried out nanoscale surface morphology on the PS substrates by modify the hydrofluoric acid (HF) to ethanol ratio (1:3, 1:6, and 1:9). In the compositional aspect it was used (AFM) to show that higher hydrofluoric: ethanol concentricity augment the porosity and particles density of wafer surface. subsequently, the etching depth given changeful directions with changing HF concentration, and the nanodimensions were clearly showed within the porous silicon layers were they produced. The anatomy of Photo luminescence (PL) specified that the energy gap E.G. was widened with increasing the porosity of wafers and the density of particles, as seem by a shifting to the blue in the PL spectrum.

In the current study, a new modular type ρ:(0,∞)×X→[0,∞) which is called t-modular is defined. Some properties are given and proven, the vector space X_ρ={ x∈X∶lim┬█(γ→0@α→∞)⁡〖ρ_α (γx)〗=0 } is defined, namely t-modular space with a norm function on X_ρ being stated

Many academics have recently concentrated on applying integral transforms to solve challenging problems in economics, biology, engineering, and medicine. In this paper, the Kharrat-Toma transform is used to issues related to population growth and decay problem. These are important topics in the fields of finance, physics, chemistry, biology, and society. Many applications show the value and efficacy the Kharrat-Toma transform is used to analyze concerns with population growth and decrease. The findings demonstrate the usefulness of the Kharrat-Toma transform in resolving problems associated with population growth and deterioration. In population growth and decay problems there is a differential equation model in mathematics that can be analyzed by the Kharat-Toma transform. We have shown its analysis and applications in this article.
