Abstract: The dynamical behavior and the synchronization of epileptic seizure dynamics, with fractional-order derivatives, is studied in this paper. Knowing that the dynamical properties of ictal electroencephalogram signal recordings during experiments displays complex nonlinear behaviors, we analyze the system from chaos theory point of view. Based on stability analysis, the system presents three equilibrium points with two of them unstable. Moreover, the system reveals attractor points fr...
Abstract CT scan is one of the most valuable tools used in the centers of modern health care and are accompanied by radiation dose greater than that of the normal radiographic and must be therefore use carefully to protect patients from radiation. The aim of this study to compare between radiation dose and image quality and to compare between CT brain protocols and radiation dose . Random samples consist of 30 patients who underwent CT brain examination. The patients data registered(age, gend...
ABSTRACT HIV/AIDS is still of major public health concern. With no vaccine in sight, it is only necessary to take a look at the sexual behaviors and practices of people living with HIV/AIDS. This study was to determine the sexual behaviors of people living with HIV attending ART clinic at District Hospital, Agbani, Nkanu-west local government area, Enugu state. METHODOLOGY: This was a descriptive cross sectional study. A systematic random sampling method was used to select 321 participants. D...

ABSTRACT A cross-sectional study was done on the Topic: Assessment of knowledge of Danger Signs among pregnant women attending ANC in KIU-TH). Pregnancy is a normal process that results in a series of both physiological and psychological changes in expectant mothers. However, normal pregnancy may be accompanied by some problems and complications which is potentially life-threatening to the mother and the fetus. Fraser et al (2003). Danger sign(s) is a term used to refer to a group of symptom...
ABSTRACT A very good reason why calculation of dose distribution is important is that it is essential to plan and replicate the treatment prior to the actual delivery of the radiation dose to the tumour. In modern radiation therapy, computer software is used for performing treatment planning. Different algorithms are employed at every stage of treatment including dose calculation algorithms. The dose calculation used for the HDRplus TPS is the TG43 formalism and just like every other TPS, th...
CHAPTER ONE INTRODUCTION 1.1 Background Brachytherapy is a term used to describe the short distance treatment of cancer with radiation from small, encapsulated radionuclide sources. This type of treatment is given by placing sources directly into or near the volume to be treated. The dose is then delivered continuously, either over a short period of time (temporary implants) or over the lifetime of the source to a complete decay (permanent implants). Most common brachytherapy sources emit ...
ABSTRACT Radiation absorbed dose for patients undergoing myocardial perfusion has been calculated for technetium-99m Hexakis-2-methoxy-2-methylpropyl-isonitrile (99mTcSestamibi) at the Nuclear Medicine Department of Abdou Moumouni University. Thirty patients were scanned and image quantification was achieved using MedisoInterViewXP® software. An activity of370 MBq (10 mCi) of 99mTc-Sestamibi was administered for stress and 1110 MBq (30 mCi) for rest. A 256 x 1024 matrix size and a speed of ...

ABSTRACT The dose to the contralateral breast for tangential breast irradiation has been estimated using Gafchromic films EBT2. The data collected consisted of measurements taken with anthropomorphic female Rando phantom. The EBT2 films were scanned and read using ScanMaker 9800XL plus and ImageJ software. A calibration curve was constructed using fourth – order polynomial fit to the data and a calibration equation was obtained from the graph which was used to convert the grey values into ...
ABSTRACT The purpose of this study was to determine an appropriate locally fabricated wood sample that could be used to replace the wire mesh incorporated at the treatment area of EBRT couch top to circumvent dose discrepancies associated with the sagging effect of the wire mesh as a result of prolonged use. Linear attenuation coefficient and transmission factor were determined at three stipulated field sizes (5cm x 5cm, 10cm x 10cm,15cm x 15cm) and two treatment depths of 0.5cm and 5cm fo...
ABSTRACT Crystalloid solutions are used in clinical practice for resuscitation and correction of electrolyte imbalances. However, up to 25% of individuals may develop dysfunctions of haemostasis following fluid infusions, complicating resuscitation and outcome. Studies on the effects of crystalloids solutions on human blood coagulation have produced conflicting results: either suggesting procoagulant effects or impaired coagulation. The mechanisms for these discrepant results remain unclear....
ABSTRACT Mean glandular dose assessment of patients undergoing digital mammography examination has been done. A total of 297 patient data was used for the study. Basic Quality Control tests were done to ascertain the performance of the equipment used. The results of Quality Control tests indicated that the three Mammography units used for this study were functioning within the internationally acceptable performance criteria. Patients with a breast thickness of 30 mm within the two age groups...
ABSTRACT The use of telecobalt machine in radiotherapy is of concern in developing countries where there is a limited resource. As such, the study was to ascertain if telecobalt (cobalt60) machine could be feasible to generate and deliver treatment plans with optimal treatment indices comparable to those of a linear accelerator (Linac). Retrospective DICOM-Radiotherapy images of patients earmarked for treatment of breast, prostate and lung cancer obtained from the European Society for Radiot...
