The purpose of this study was to assess the environmental radiological hazards associated with elevated levels of radon gas in drinking water. Using passive (CR-39 plastic detector) and active (RAD 7) detectors, the radon levels in the air and drinking water (tap water) of 124 homes in 31 distinct locations in Iraqi Kurdistan were determined. Almos...

This study was undertaken to investigate the influence of static magnetic field (SMF) on bone marrow cellular density (BMCD) variation proportionally to bone trabeculae. Female albino Wistar rats exposed with 2.4 ± 0.2 millitesla for 1–4 weeks duration continuously versus 1 h, 2 h, 6 h, and 8 h/day. Trephine biopsy of femurs bone was examined under...

Introduction: The influence of electric field on the nature of blood flow and cells is controversial. Erythrocytes sedimentation rate (ESR) examination is a recommended approach to diagnose a few health conditions such as polymyalgia rheumatic and temporal arteritis. Aim: In this study, we aimed to evaluate the effect of electric field on ESR of hu...

In this study, the influence of the static magnetic field (SMF) on blood platelets (PLTs) has investigated in-vivo experiments. Female albino rats exposed to the magnetic field for 1hr, 2hrs, 4hrs, 6hrs and 8hrs per day during 1-4 weeks. Platelet counts did not vary significantly for 1hr of exposure. The 2hrs/day exposure for 1 week and 6hrs/day ex...

This study aimed to investigate the in-vivo effect of a static magnetic field (SMF) on blood falling time and velocity in a capillary tube. We generated a magnetic field using Helmholtz coils. We exposed rats with 2.4±0.2mT for a duration of one-four weeks and 1-8hrs/day. Blood samples were withdrawn and passed through a capillary viscometer under...

In this study, we investigated the effect of the static magnetic field (SMF) on white blood cells (WBCs) for female albino rats using a fabricated exposure system of SMFs. Five main groups of animals exposed to 2.4±0.2 milli-Tesla (mT) for four weeks continuously. Five main groups (each group = 4 subgroups) have exposed to a different time of expos...

This study was undertaken to investigate the influence of a homogenous and uniform static magnetic field (SMF) on the main blood cell counts in vitro experiment. Fresh blood samples were collected from albino rats and exposed to SMF (2.4, 6, 25, 50, 75, and 100 mT) versus 15–60 min. Results showed a significant change of blood counts under the low...

Impacts of different materials (cartoon, PVC, wood, plastic, iron, glass, and Mild steel)) on the intensity of a uniform static magnetic fields (SMF) proved through designing a multi Helmholtz coil connected in series. The design provided a magnetic field ∼ 4 mT depended on applied currents and the distance between the coils, also it has provides a...

The present study was undertaken to investigate the influence of the static magnetic field (SMF) on the platelets and red blood cells counts (RBCs), haemoglobin (HGB), haematocrit (HCT), mean cell volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in female rats (in-vitro). The results were analys...

The surface morphology evolution and de-wetting properties were studied of polystyrene (PS), poly(methyl methacrylate)(PMMA) thin films, and thin PS/PMMA bilayer films above silicon substrates by using Optical microscopy approach. A PS film with 18.66 nm, PMMA with 82.5 nm and the bilayer of PS/PMMA with 85.33 nm (before annealing) have been deposi...

In this study, the simulated single layer Anti-Reflected Coating (ARC) on silicon solar cell that based on the refractive index limit of silicon dioxide (SiO2), zinc oxide (ZnO) and zinc sulphide (ZnS) are presented. Two simulations of (ZnO) and (ZnS) coating were simulated to compare with (SiO2) ARC on silicon solar cell surface. These simulations...

The nature of charge injection has been investigated across the gold (Au) / aluminium (Al) - regioregular poly(3-hexylthiophene), rrP3HT, interface as a function of channel length of the two electrodes. The sheet resistance (R_□(□)) of rrP3HT in contact with Au/Al electrodes and contact resistance (bottom contact and top contact) are also measured....

Nickel oxide thin films have been prepared from a nickel acetylacetonate (Ni(acac)) precursor for use in bulk heterojunction organic photovoltaic devices. The conversion of Ni(acac) to NiOx has been investigated. Oxygen plasma treatment of the NiO layer after annealing at 400 °C affords solar cell efficiencies of 5.2%. Photoelectron spectroscopy sh...
