Knowledge management is a field with a lot of potential that can benefit individuals as well as different types of organizations. Despite this fact, most organizations in Kenya have focused on knowledge storage, but have not adopted sharing of the stored knowledge. This study examined the adoption of mobile technology for knowledge management in Mahashakti Kenya Limited, Athi River. The study was guided by the following objectives: To assess the extent of adoption of mobile technology fo...
Abstract: The exchange rate is one of the macro-economic variables that have an impact on macroeconomic with its different sectors and the Exchange rate policy is one the most important policies that adopted by some countries to solve some of the economic problems. Therefore we must stand on timeline impact of the exchange rate in Sudan and build a predictive model for predicting exchange rates in Sudan. It requires finding suitable models to the nature of commercial time-series data. We mus...
Abstract This study was conducted in Khartoum state- Omdurman (Ombada hospital and Altohamy health center), during the period between August 2018 to April 2019. The study is case- control study, one hundred and fifty individual were enrolled in this study, (100 malaria patients and 50 individuals as controls). 5ml of blood sample was collected from each participant and investigated for malaria infection by both microscopic examination and immunochromatographic test (ICT), serum ferritin leve...
Abstract Breast cancer is the disease most common malignancy affects female population and the number of affected people is the second most common leading cause of cancer deaths among all cancer types in the developing countries. Nowadays, there is no sure way to prevent breast cancer, because its cause is not yet fully known. But there are things you can do that might lower risk such as early detection of breast cancer can play an important role in reducing the associated morbidity and m...
ABSTRACT Trust is a major factor in the internet business. This is not surprising as it is very convenient for cyber criminals to swindle unsuspecting customers. AUN SafeShop is an online store for the American University of Nigeria (AUN) Community. AUN SafeShop is a platform for AUN staff, students and faculty to buy and sell new or fairly used items among themselves. This platform is a lot safer for members of the AUN Community because it will be a near transparent system and it will be ve...
ABSTRACT In this project, we shall implement the hierarchical clustering algorithm and apply it to various data sets such as the weather data set, the student data set, and the patient data set. We shall then reduce these datasets using the following dimensionality reduction approaches: Random Projections (RP), Principal Component Analysis (PCA), Variance (Var), the New Random Approach (NRA), the Combined Approach (CA) and the Direct Approach (DA). The rand index and ARI will be implemented ...
Industries worldwide are facing a technological revolution where there is a need for technologies that can speed up business processes with more safety and transparency. The real estate industry is among many other industries that would benefit from such technologies due to the magnitude of financial transactions handled. The current management strategy employed by real estate owners depends on a number of intermediaries, including brokers, agents and banking service providers. This strategy ...
Abstract Rice husk (RH) was collected from a rice mill in central Sudan and was used as a dual source for silica and cellulose. Amorphous silica was extracted from rice husk ash (RHA) through chemical treatment with nitric acid (3M) and combustion. It was then used to extract amorphous silica through dissolution in aqueous alkali solutionvNaOH (1M) and subsequent gelation in acidic medium following the sol-gel process. Pure cellulose was obtained from RH after complete removal of lignin and h...
Abstract Complex Analysis And Conformal Mapping Play A Central Role In Mathematical Sciences And Theoretical Physics. The Traditional Applications Include Differential Equations, Harmonic Analysis, Potential Theory And Fluid Mechanics. Of Particular Interest To This Study Is The Complexfied Minkowski Space And Its Corresponding Spin Space Model Which Is Appropriate For The Description Of Quantum Field Theory. Moreover, For An Ambitious Scheme To Incorporate Gravitational Field In A Quantized...
Abstract Nowadays, noble metals nanoparticles are considered as the promising metals due their fascinating physical properties. Among the noble metals, silver nanoparticles ( Ag-NPs) exhibit a sharp and distinct absorption band in the visible region of electromagnetic spectrum associated with localized surface Plasmon resonance. Moreover, Ag NP has high resistance to oxidation and antibacterial activity which make it desirable for a wide range of applications particularly in biomedical scienc...
Abstract In this study scintillation counter is used for investigating and identifying the radioactive substances in the sample and determining their activities by means of gamma ray spectroscopy, sodium chloride as an example in order to determine its activity which reveals poor activity
Abstract This study aimed to detect extended specterum beta lactamase genes in Gram negative bacteria associated with Urinary Tract Infections in Khartoum State. Ninty one urine specimens were collected in this study. Samples were cultured on CLED agar and bacteria were identified by the conventional biochemical methods. Modified Kirby-Bauer method was usedfor sensitivity testing by using the following antibiotics: Gentamicin, Ciprofloxacin, Co-trimoxazole, Imipenem and Ceftazidime. A total ...
Abstract There are several obvious observable evolutionary evidence among all the population of known pulsars, but a consistent description of this evolutionary trend is generally lacking in the literature. In this study, we provide a consistent interpretation of this evolutionary effect, on the ground that the exchange of moment of inertia with time between superiud component and the solid crust component as the temperature of the neutron star drops is a signicant process of energy loss in ...
ABSTRACT We re-examined the phenomenon of rotational instability in radio pulsars on decadal timescales using a sample of 315 radio pulsars whose spin-rates [rotation period (P) and spin-down rate ( P) ] have been measured on, at least two different epochs. The first stage of our analysis involves a direct comparison of the measured values of P and P at two epochs that are ~ 10 - 20 years apart in order to estimate the fluctuation in the parameters. The results show that the fluctuation in t...
Abstract Polyethylene/silica Nano composite was synthesized in different concentrations (2%, 3%, 4%, 10%, 20%, 30%, 40%, and 50%) The samples were subjected to physical evaluation; the result showed that the amount of silica is changed the optical properties (the maximum absorbance was 284 nm) and the composite had moderate refractive index in infra red region but it is de- shielding in part of ultra violet region. Mechanical properties was enhanced .the highest load was 5.4kg to sample...
