Understanding The Implementation Of Direct Health Facility Financing And Its Effect On Health System Performance In Tanzania: A Non-Controlled Before And After Mixed Method Study Protocol

Abstract Background: Globally, good health system performance has resulted from continuous reform, including adaptation of Decentralisation by Devolution policies, for example, the Direct Health Facility Financing (DHFF). Generally, the role of decentralisation in the health sector is to improve efficiency, to foster innovations and to improve quality, patient experience and accountability. However, such improvements have not been well realised in most low- and middle-income countries, with ...

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...

Development And Validation Of An Assay For Bisoprolol Fumarate And Hydrochlorothiazide Multicomponent Drug

Abstract A simple, precise, accurate and economical Reverse phase HPLC with a detection UV, method was developed and validated for the simultaneous determination of Bisoprolol fumarate and Hydrochlorothiazide in pharmaceutical formulations. Better separation was achieved using Cyanide column (250mm × 4.6mm, 5μm), maintained at 30 ͦC. The mobile phase was composed of buffer: methanol in the ratio of 82:18 (v/v), (the buffer was 1% solution of tetra butyl ammonium hydroxide, adjusted to pH ...

A Model For Prediction Of Financial Distress In Sudanese Banking System Using A Newly Built Data Set.

Abstract Bank failures threaten the economic system as a whole. Therefore, predicting bank financial failures is crucial to prevent and/or lessen its negative effects on the economic system. Financial crises, affecting both emerging markets and advanced countries over the centuries, have severe economic consequences, but they can be hard to prevent and predict. This is originally a classification problem to categorize banks as healthy or non-healthy ones in order to design the required measu...

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.

The results presented as mean ± SD were the mean of ESAK was (mean ±0.31 SD) an...

An Automatic Question Answering System For The Arabic Quran

Abstract This thesis investigates Question answering system in general and then applying it in a specific domain: Arabic language and Holy Quran. A corpus of questions and answers from Albagarah and Alfatihah chapters was built, using three types of files: excel worksheet, texts and database table. This corpus was collected from many resources and validated by Islamic scholars from Gabrah college. The thesis contains six chapters: Chapter one defines the problem statement, objectives and mot...

Performance of Low-Cost Agar from Gracilaria salicornia on Tissue Culture of Pleurotus HK-37

Abstract Currently, the demand of Pleurotus HK-37 (oyster mushroom) in Tanzania is growing rapidly due to the increasing of awareness on its nutrition, health, and economic benefits. Despite the increasing demand, the availability of strains of Pleurotus HK-37 species is still a challenge due to high cost of tissue culture technology. ,e high cost of importing agar seems to be among the factors for this failure. ,is study aimed at investigating the performance of low-cost agar from local Grac...

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 ...

The Challenges Facing Adoption Of Mobile Banking In Tanzania: A Case Of Nmb Chake-Chake Pemba

ABSTRACT The aim of the study was to investigate the challenges which face the adoption of Mobile Banking services (MBs) that cause customers of NMB Bank not interested to use this service as expected. The result of this study will assist NMB Bank in managing and improving the services which mobile banking provide and optimize the usage of service to customers and the society at large. The study identifies the factors which could lead to improve the usability of services to customers. Quanti...

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...

Do marine phytoplankton follow Bergmann’s rule sensu lato?

ABSTRACT Global warming has revitalized interest in the relationship between body size and temperature, proposed by Bergmann’s rule 150 years ago, one of the oldest manifestations of a ‘biogeography of traits’. We review biogeographic evidence, results from clonal cultures and recent micro- and mesocosm experiments with naturally mixed phytoplankton communities regarding the response of phytoplankton body size to temperature, either as a single factor or in combination with other facto...

GC-MS Analysis Of Capsicum Annum Fixed Oil And Assessment Of Antimicrobial Activity

Abstract In this study, the fixed oil of Capsicum annum was extracted from seeds with n-hexane at room temperature. The oil was analyzed by gas chromatography-mass spectrometry (GC-MS) GC-MS analysis of the studied oil revealed the presence of 27 components. The major constituents were: octadecadienoic acid methyl ester (56.57%), hexadecanoic acid methyl ester (17.60%).Minor constituents were octadecenoic acid methyl ester (5.62%), methyl stearate (5.50%), and stigmasterol (2.37%). The oil w...

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...
