Monte Carlo Modeling Of Fast Neutron Moderating System Suitable For Use In Boron Neutron Capture Therapy

Abstract There is no one treatment for cancer and the search for ways to combat cancer have led to many different treatments, including surgery, chemotherapy, and radiation therapy. However, these treatments are not always effective, and in such cases new treatments must be developed. Boron neutron capture therapy (BNCT) is a treatment that has been proposed to combat brain tumor and Neck tumors, two tumors that are resistant to traditional cancer therapies. Boron neutron capture therapy (BN...

Evaluation Of Radiation Protection In The X-Ray Departments In The Blue Nile State Hospitals

Abstract The aim of this study was to evaluate the radiation protection in the x –ray departments of the Blue Nile State. Four x –ray departments were selected in four hospitals. The study was conducted during the period from March to July 2017. The radiation doses were measurement in the x -ray rooms, dark rooms, doors and offices adjacent to the x-ray rooms using a survey meter. The final results showed that the doses received by the workers and public in these hospitals were within th...

Using Industrial Radiography In Pipeline

Abstract This research desiccation with the issue of radiography in petroleum pipelines. This is to make sure that welding is quality and that there are no defects inside the metal. That ensures the passage of raw safety. Also used radiation test to detect any defect inside the metal. also used some method to inspect like penetrant testing or magnetic participle testing.

Some Aspects Of The Higgs Boson In The Standard Model

Abstract In this thesis was studied some aspect of the Higgs boson in the Standard Model of Particle Physics. Also was calculated the Higgs boson as function of its mass as well as the branching ratios from to . Furthermore was calculated the Higgs decay rates into and gauge bosons and fermions in the Standard Model of Particle Physics. We find that in order for the Higgs to decay to any particle in this model, the mass of the Higgs should be . Also we found that, the total Higgs decay rate ...

Through the study of some scientific papers in this area, and aiming to summarize findings, and to facilitate the search for the interested researchers according to their needs, moreover, to highlight weather more research is needed to be conducted in this field or wh...

Renewable Energy Advantages And Disadvantages

Energy plays a major role in economic activity and is considered an important indicator of the growth and development and the progress of nations and prosperity, where we find that the countries most energy-consuming is the advanced and developing countries, and where the industry is booming in the biggest developing nations, in general, energy resources, renewable resources such as solar, wind, water and other untapped after broadly, and other non- renewable, such as coal, natural gas, oil a...

Effect Of Laser Pasteurization On Production Of Yoghurt

ABSTRACT This research was undertaken to compare yogurt produced from unpasteurized milk, laser pasteurized milk and heat pasteurized milk. Milk samples were obtained from SUST farms-Shambat -North Khartoum - Sudan. ND: YAG laser used to pasteurize the first sample, the second sample pasteurized by heat and the third one was left as obtained to be control sample. Yogurt is produced by bacterial fermentation of milk. The results showed that the use of laser in pasteurization is not differ fro...

Unification Of Newton And Relativistic Energy Conservation And Gravitational Equations

Abstract In this work it was shown that the energy conservation in Newtonian and generalized special relativity are equivalent. It also shown that when the energy is conserved the definition of force in terms of momentum Leads to its definition in terms of potential in both Newton and generalized special relativistic mechanics. Centrifugal force plays an important role in physic. It can explain motion of planets beside most macroscopic circular motion. The equation of motion in a circular or...

Electrochemical Performance of Laser Modified Zinc Electrode

Abstract In this research CO2 laser has been utilized to produce textured surface in zinc foil to use in electrochemical cells as cathode, modified surface was obtained by making two parallel lines in 1mm,using CO2 laser with (ʎΞ10600nm) and power of 90 watts and 10mm/s speed. The experimental evidence of the effect of surface texturing on the performance of electrochemical cell was demonstrated and investigated. The results show considerable increase in cell voltage with the textured cath...

Study Of Radioactivity For Waste Water Of Khartoum Refinery

Abstract The hazardous waste water from industrial sector is now coming one of major threats to environment, the need to study the radioactivity from such kind of waste is of crucial importance, this study is carried out to path the way in studying the radioactivity of waste water in Sudan. Since the industrial waste water is a threat to environment, the impacts should be accessed through study of radio activity of such materials. To study the radio-activity of Khartoum Refinery waste water,...

Investigation of the Effects of Diode Laser (532 nm) on Human Whole Blood by UV-Vis Spectroscopy and CBC in-vitro Study

Abstract Lasers are widely used in the modern medicine as important parts of different types of equipment. Laser beams of different powers, wavelengths and optical properties are used in surgery, cosmetology, therapy, diagnostics and number of other medical areas. The present study aims to evaluate the effects of diode laser with wavelength 532 nm on blood optical absorbance property and complete blood count (CBC). The irradiated and non irradiated whole blood, plasma and blood cells samples ...

A Selective Window For Indoor Thermal Comfort In Building

ABSTRACT Buildings in Sudan experience significant amount of heat gain through windows and this affects the thermal comfort of buildings' occupants. There are many commercially available smart windows that control the reflection and transmission of visible light and infrared radiation, but they suffer from the high cost, low transmission of the visible light and some of them require external power for operation. The proposed glazing is relatively simple and it does not need any external sour...

Mg Doped On Zno To Investigate The Effect Of Mg Ions On Optical Properties And Bandgap Of Zno Nano-Particle

Abstract In this study, the optical (absorption coefficient and transparency) properties and the energy band of Zinc Oxide nano particles doped with magnesium ion were investigated within different weight percent namely (0.00 , 0.05 and 15% of weiht) was synthesized , the ZnOnano particles was prepared using sol–gel method.

Study Of Physical And Chemical Characteristics For Hibiscus Sabdariffa L Using Different Techniques

Abstract Two types of hibiscussabdariffa L were prepared (red and white) in the form of powder respectively and the samples were exposed to the XRF meter to identify elements and their concentrations of the samples. Also the samples were exposed to X-ray to study the crystal structure. It was found that the material was amorphous. Also some of the samples were dissolved in cold and hot water in the form of a solution and were characterized by UV-VIS spectrometer to study the absorbance ...
