ABSTRACT: The dose and dose-rate is the basic physical factors determining the effects of ionizing radiation on biological systems. It ispredicted that an employers exposed to low dose mayspendfor several months in a radiation field without becoming alarmed. The study aimed to discuss the evaluation of low dose ionizing radiation (IR) effect on some blood components and liver enzymes in radiological staff. Peripheral blood cells count and liver enzyme (SGOT and SGPT) were determined for 11 workers (divided into 2 groups) pre- and post-irradiation. An attempt to explain the blood changes resulting from both irradiation and time is given. There was a strong liner correlation between............

ABSTRACT: In this paper, we proposed the smallest particles of the composition of the earth, the role of hydrogen atoms, according to the gravitational wave theorem, the variable field theorem and mathematical modeling analysis. The roles and relations of protons and neutrons are elucidated. Any material is a combination of hydrogen atoms, and finally three kinds of material basis which form the earth were prompted. New principle of inter atomic periodic law was proposed............

ABSTRACT: It is important to measure the bulk-etching rate for any solid state nuclear track detectors, because they have an application in different fields of sciences. The effect of gamma rays emitted from 60Co source with different doses on LR-115 detector was studied. The bulk etching rate of the detectors was measured before and after irradiation using gamma source. From the results the values of the bulk etching rate of LR-115 without gamma rays have been 3.10 μmh−1 and that under gamma irradiation with different doses were ranged from 4.60 to 8.77 μmh−1. This means that the values of the bulk etch rate increase with increasing gamma doses.

Keywords: LR-115detector, Bulk etching, Gamma, Dose.

ABSTRACT: A simple acoustic measurement method has been applied to demonstrate Poisson distribution of bubbles sparkling at a water surface. The quality of sparkling water has been determined by quantifying the characteristic time of decay of number of air bubbles sparkling at the surface of water served to consumers. The average sound frequency of the bubbles at sparkling has been found dependent on the chemical composition of the water (carbon dioxide and minerals concentration). The acoustic measurement method proved to be fast and reliable for determining the quality of appearance of served sparkling water.

ABSTRACT: The nonlinear optical single crystal of bisthiourea zinc acetate (BTZA) was grown successfully by slow evaporation technique using water as solvent at room temperature. The lattice parameters of the grown crystal were determined by X-ray diffraction studies. The quality of the grown crystal was examined by scanning electron microscopy (SEM).The optical transparency was determined by UV-visible and photoluminescence spectroscopy studies. The thermal behavior of the grown crystal was investigated by DTA and TGA analysis. The presence of functional group was studied using FTIR spectra. The second harmonic generation (SHG) of BTZA was confirmed the nonlinear property of the crystal by Kurtz powder technique.

ABSTRACT: The aim of this study was to estimate the Entrance Skin Dose (ESD), the eye lens dose and the thyroid gland dose for adult patients undergoing diagnostic X-ray examinations of the skull and the cervical spine in some hospitals in Sudan. A total of 120 patients were evaluated. The ESD was calculated using the relationship between the X-ray tube output and the exposure parameters. The eye lens dose and the thyroid gland dose were calculated from the ESD using Xdose software (Version 2). The results showed that the mean ESD was 0.636 mGy, 0.589 mGy and 0.694 mGy for the antero-posterior (AP) cervical spine, lateral cervical spine and lateral skull respectively...........

ABSTRACT: In this paper, we use the gravitational wave theory to elucidate the propagation pattern of light between the electrons of the gravitational waves. The light has the entanglement between the periodic and the optical blocks with the same properties. The degree of entanglement between the light blocks is expressed by relative energy. Each photoperiod contains four sub-process morphologies, each sub-process morphology, forming a separate, electron-group and entangled form of relative energy set.

Keywords: light; gravitational wave; wavelength.

ABSTRACT: A method for recording good images on high resolutionphotographic plate and their retrieval was described.This method depend on the modulating optical signal by a crossed diffraction grating. Two symmetrical first and second orders werefiltered to modulate the real amplitude object.These ordersrepresent the optical modulated signalson the photographic plateby a given frequency of crossed diffraction grating and another frequency from itself crossed diffraction grating respectively. Different irradiance distributions for a different modulated signals were appeared. Improved images were obtained from a given modulating signal. The irradiance distributions and visibilitywere calculated theoretically and experimentally

ABSTRACT: Recycling of waste plastics is of great interest in solid waste management and characterization of waste plastic. The change of stress-strain behaviour of waste plastic depends on environment factors and the number of days exposed to heating at day time and cooling at night. Stress-strain behaviour of commercial grade polypropylene at the end of each thermal fatigue cycles was studied. Heating-cooling cycle was set to 8 hours for heating at a specified temperature (80°C, 100°C, 120°C 140°C and 160°C) and air cooling over night at ambient temperature........

ABSTRACT: Bulk samples of the system Ge100-xSbx, where x = 5, 50 and 95 at. % were prepared by the melt quenching technique. The disorder-order transition has been investigated for the alloys annealed at 323, 348, 373 and 393 K for different times.X-ray and thermoelectric power were recorded for the annealed samples and the results revealed crystalline Ge, Sb and Ge-Sb phases. It was found that the values of the thermoelectric power decreased as a result of raising the annealing temperature while increasing the Sb content leads to a an increase in the thermoelectric power.

Keywords: Thermoelectric power, structure, amorphous alloys and x-ray.

ABSTRACT: With the appearance of knowledge mankind began to research about the existence of atom and where magical force ruled the minds of the people and all universes. If I ask one question, how much break of piece of matter in half and then break it in half again, how many breaks will be - we have to make before we can break it no further ? Somebody thought it ended at same point , a smallest possible bit of matter and that is called basic matter particles atoms. Fundamentally the mystery of creation have been hidden in the high energy collision and the most powerful constructed engine is human structure, that which demonstrated powerful of telepathy. Power of far seeing etc. Scientist are going to break again break a piece of matter and philosophers are going to research to the cause of matter.................

ABSTRACT: The optical properties of quasiperiodic SFMs of ZnS/MgF2 are theoretically investigated, many transmission peaks have been observed for normal incidence of light and if the symmetry is disrupted, these peaks have clearly shrunk. So, it is demonstrated that the mirror symmetry plays an important role in obtaining the perfect transmission features in SFMs.

ABSTRACT: There are numerous unanswered scientific doubts/phenomena in Nature which still perplex scientific researchers currently. To solve these puzzles, unveiling the ultimate structure of matters, which make up the Nature world, is essential. Here four hypotheses, namely the fundamental matter component (basic particle) and its property, construction process of the basic particles into other particles/matters, repulsion of particles of the same type, and direct relationship between matter and energy, are proposed. These simple hypotheses can well explain some natural phenomena, such as the existence of huge atom energy and various particles/matters of different properties, and conversion balance between matters and energy.............
