The dependence of the energy losses or the stopping power for the energies and the related penetrating factor are arrive by using a theoretical approximation models. in this work we reach a compatible agreement between our results and the corresponding experimental results.
Background: Since declaring coronavirus disease 19 as a pandemic by the World Health Organization, a great concern was directed toward pregnant women and their fetuses. Despite the substantial impact of COVID-19 disease on pregnancy, there is a scarcity of national researches discussing this important issue.
Objectives: To study the relationship between peripheral blood abnormalities and COVID-19 in pregnant women.
Patients and methods: A case control study was conducted in the labour wards of Baghdad Teaching Hospital in the Medical complex / Baghdad /Iraq during the period from 1st of February till 31st of July, 2021. Fifty pregna
... Show MoreInformation systems and data exchange between government institutions are growing rapidly around the world, and with it, the threats to information within government departments are growing. In recent years, research into the development and construction of secure information systems in government institutions seems to be very effective. Based on information system principles, this study proposes a model for providing and evaluating security for all of the departments of government institutions. The requirements of any information system begin with the organization's surroundings and objectives. Most prior techniques did not take into account the organizational component on which the information system runs, despite the relevance of
... Show MoreBackground: Ventricular septal defect (VSD) is the most commonly recognized congenital heart defect. Isolated VSDs represent about 20-30% of all congenital cardiac malformations and have a prevalence of 1- 2 % per 1,000 live births.
Objective: This study is planned to review the outcome of surgical closure of VSD at Ibn Al-Nafees Teaching Hospital (Department Cardiac Surgery) Baghdad/Iraq.
Patients and methods: This study includes 50 cases of VSD both isolated and VSD associated with other congenital malformations admitted and underwent surgical repair of age range between 3 to 28 years and weight range between 9 to 80 kg. Different type of VSD, were found and repaired whether isolated or with other associated congenital anomalies
Iraq economy suffered, nor , still many difficulties and problems , including oil derivatives crisis that emerged in 2004 and was the most prominent features of the inability of local production to meet the needs of the increasing growth of consumption, the crisis has cast a shadow on the growth of national in general, and citizen living in particular. Therefore, the real test of crisis and challenge to the capacity of government agencies to manage the crisis and control and reduce its harmful effects, which disappear in a region or sector, even begin to appear in another, given the multiplicity and complexity of third-party solution for remedying the negative consequences of deliberate.
The interplay of species in a polluted environment is one of the most critical aspects of the ecosystem. This paper explores the dynamics of the two-species Lokta–Volterra competition model. According to the type I functional response, one species is affected by environmental pollution. Whilst the other degrades the toxin according to the type II functional response. All equilibrium points of the system are located, with their local and global stability being assessed. A numerical simulation examination is carried out to confirm the theoretical results. These results illustrate that competition and pollution can significantly change the coexistence and extinction of each species.
This study aimed to prepare a program (physical-nutritional) for women with polycystic ovary, as well as to identify the effect of this program on some body measurements and the incidence of polycystic ovarian syndrome in the research sample. A total of 12 women (aged 20-25 years) with Polycystic Ovary Syndrome (PCOS) participated in the randomized controlled trial design. They were divided equally into two groups (experimental and control group). The experimental group received the physical-nutritional program accompanying the treatment program, while the control group received only the instructions of the specialist doctor and the treatment program prepared by them. The two researchers applied their nutritional progr
... Show MoreAsphaltene is a component class that may precipitate from petroleum as a highly viscous and sticky material that is likely to cause deposition problems in a reservoir, in production well, transportation, and in process plants. It is more important to locate the asphaltene precipitation conditions (precipitation pressure and temperature) before the occurring problem of asphaltene deposition to prevent it and eliminate the burden of high treatment costs of this problem if it happens. There are different models which are used in this flow assurance problem (asphaltene precipitation and deposition problem) and these models depend on experimental testing of asphaltene properties. In this study, the used model was equation of
... Show MoreSilymarin (SM) is a plant extract obtained from Silybum marianum( milk thistle) . It is class II type drug according to Biopharmaceutics Classification System with low bioavailability due to its low solubility.
Micro/nanonization during crystallization, surface modification and crystal structure modification may improve the dissolution rate of poorly water-soluble drugs.
The aim of this study was to increase the water solubility and dissolution rate of SM by in-situ micronization using solvent change either by stirring or ultrasonic method. Stabilizers like Gelatin, PVP-K30, HPMC15, Pulullan were used to stabilize the prepared ultrafine crystals. Effect of type and concentration of hydrophilic polymer, solv
... Show MoreBackground: High serum molybdenum level may contribute to dialysis related bone disease in patients requiring long term hemodialysis in fact massive molybdenum accumulation causes joint deformity and arthritis
Objective: To asses the level of molybdenum in uremic patients requiring long term hemodialysis and impact of hemodialysis on the serum level of molybdenum before and after hemodialysis
Patients and methods: Eighty patients complain from chronic renal failure on long term hemodialysis aged (16 to 65) years, serum molybdenum was measured before and after hemodialysis
Result: The mean serum molybdenum level in 80 patients requiring long term hemodialysis was elevated before dialysis (0.29 + 0.17 nmol/mL) and even after dialy
Background: Hand osteoarthritis (HOA) is a common joint disorder leading to considerable pain and with substantial impact on hand function. Carotid intima-media thickness (CIMT) is a measurable index of the presence of atherosclerosis. Increased CIMT is associated with increased cardiovascular mortality and morbidity, so early diagnosis and management may improve quality of life.
Objective: To assess the relationship between carotid intima-media thickness (CIMT) and hand osteoarthritis (HOA), and to evaluate the predictors of this relationship.
Patients and Methods: One hundred Iraqi HOA patients and 100 healthy controls were included in this study. Full history was taken and complete clinical examination was done for all patients
