the energy that a radiation source emits as light (photons), electromagnetic waves, or particles is known as radiation. X-ray is one type of ionizing radiation that falls within the electromagnetic wave category of short wavelengths. Because of their short wavelength. X-ray is a type of ionizing radiation that is used in a constantly growing number of diagnostic procedures. X-ray diagnostic imaging has been employed in the medical field for more than a century(Hariyoto et al., 2020). Radiation has advantages for human health, but there is also a risk. the impacts of Radiation on Fertility it is an oligospermia, or a reduction in the number of sperm cells, which is already possible after radiation exposure of 0.15 mGy. It Leads to impedes the process of generating the resultant sperm cell through a deterministic effect. (Tuieng et al., 2021). Infertility affects 1 in 6 couples globally. Nearly 50% of infertility cases are caused by male causes. Although low sperm counts, abnormal sperm morphology, and impaired sperm motility are recognized causes, the underlying reasons remain unknown in 25% of instances.(Inhorn and Patrizio, 2014). Human infertility is reliant on the meiotic process, which leads to the development of germ cells. This procedure is extremely radiation-sensitive. the relationship between radiation exposure and infertility is thought to originate from DNA damage induced by free radicals originating from radiation ionization. DNA damage might cause some mutations or cause cell death (apoptosis). (Skrzypek et al., 2019) Even though X-rays are one of the most common diagnostic instruments used on patients, not much study has been done on the impacts of X-ray exposure on medical workers. One condition that is commonly observed in medical workers who are exposed to radiation regularly is infertility. For the diagnosis of many illnesses, radiodiagnosis tools like C-ARM, and CT-SCAN. X-rays are still the mainstay. Frequent usage of small amounts of X-ray radiation can have an accumulating effect that results in other abnormal epigenetic patterns and DNA damage. To reduce the radiation exposure of medical workers, further study is required to find the best X-ray doses, times, and saf
Aromaticity, antiaromaticity and chemical bonding in the ground (S0), first singlet excited (S1) and lowest triplet (T1) electronic states of disulfur dinitride, S2N2, were investigated by analysing the isotropic magnetic shielding, σiso(r), in the space surrounding the molecule for each electronic state. The σiso(r) values were calculated by state-optimized CASSCF/cc-pVTZ wave functions with 22 electrons in 16 orbitals constructed from gauge-including atomic orbitals (GIAOs). The S1 and T1 electronic states were confirmed as 11Au and 13B3u, respectively, through linear response CC3/aug-cc-pVTZ calculations of the vertical excitation energies for eight singlet (S1–S8) and eight triplet (T1–T8) electronic states. The aromaticities of S

The optimum operating parameters of initial Cr (VI) concentrations, adsorbent dose, pH and contact time were 50 mg/l, 0.7625 g, 3 and 100 min, respectively. At these conditions, th
The study deals with China's soft power and diplomacy in the Middle East, and it focuses specifically on the tools and foundations of China's soft diplomacy and how it achieves its goals in the region in addition to its challenges in the region. In this regard, the study also focuses on the Chinese Belt and Road Initiative and its soft foundations and how they serve China’s diplomacy and soft power in the region. The study ends with a set of conclusions, perhaps the most prominent of which is that diplomacy and soft power have become a fundamental pillar of China's foreign policy to achieve its foreign goals and to establish an international system compatible with China's principles. As for the Middle East, China has established a poli

A large evidence base suggests that diabetes is associated with an increased prevalence, extent and severity of gingivitis and periodontitis and loss of teeth. Many patients do not aware that they are diabetic.Objectives:The aim of the current study was to assess a fast, non-invasive, safe procedure to screen for diabetes and its severity in dental clinics and to assess the change in blood glucose level before and after tooth extraction during periodontalResults: there were no significant differences between the blood samples collected before tooth extraction from finger puncture method (FPB) and the gingival

In spite of the importance of the human capital in the knowledge organization, The accounting as an information systems, does not give a great deal of consideration to the human capital, and does not treat investment in it as an original factor, but it shows it on the base of salaries and payrolls that is appears in the financial statements as a revenue expenditure. As a result of that the financial statement are not a true expression of the actual status and then some of the decisions taken under the present circum

Objectives: To detect maternal serum levels of proinflammatory cytokine (Interleukine-6, Interleukin-8) with preterm delivery in pregnant women suffering from gingivitis.
Cases and methods: In this case-control study, a total of 85 pregnant women, were included in the study, of whom 55 had gingivitis: 25 preterm deliveries and 30 full-term deliveries. Thirty healthy pregnant women with healthy gingiva were in the control group. They were selected from Al-Ramadi Teaching Hospital for Gynecology and Pediatrics, from November 2022 to May

This military campaign was helped to formulate its speech by many institutions, research centers, and knowledge and intelligence circles in order to mobilize public opinion gain supporters and face the opponents by different means depending on a variety of styles to achieve its required effects.
After the US occupation of Iraq, US media fighters sought to influence the Iraqi public opinion and making them convinced them of the important presence of US military forces in Iraq which necessitated finding its justification through the use of persuasive techniques in its intensive propaganda campaigns.
