Performance Of A Customized Cryo-Cooling System Designed For The Measurement Of The Lifetime Of Nuclear Excited States At Cryogenic Temperatures, Innocent J. Lugendo

Tanzania Journal of Science

Theoretical predictions that the lifetime of nuclear excited states can be varied if the nucleus is subjected to a condition that allows multiple coherent emission and re-absorption of gamma photons by the nucleus is of much interest to the nuclear physicists. Therefore, an experiment has been designed to study the possibility of lifetime variation. Based on the theory requirements, lifetime variations can be observed when the nucleus is cooled to cryogenic temperatures. Both the cryo-cooling system and the fast timing system have been developed. In the current work, the design, operation and performance of the developed cryo-cooling system is discussed. …

Anempirical Performance Comparison Of Meta-Heuristic Algorithms For School Bus Routing Problem, Sherehe Semba, Egbert Mujuni

Tanzania Journal of Science

School Bus Routing Problem is an NP-hard Combinatorial Optimization problem. Thus, mega-heuristic algorithms are widely used to solve instances of the School Bus Routing Problem with large data. In this work we present a model of the School Bus Routing Problem and empirical performances comparison between three meta-heuristic algorithms named Simulated Annealing (SA), Tabu Search (TS) and Ant-Colony Optimization (ACO) on the problem. We have analyzed their performances in terms of solution quality. The results show that all three algorithms have the ability to solve the School Bus Routing Problem.

Status Updates On Plastics Pollution In Aquatic Environment Of Tanzania: Data Availability, Current Challenges And Future Research Needs, Dativa J. Shilla

Tanzania Journal of Science

Plastics are the most useful materials invented by man, and have brought great convenience to our daily lives but not without problems. Inappropriate disposal of wasted plastics has caused serious environmental problems. Over the past decade, microplastic debris in both marine and freshwater systems have become an emerging issue. A literature review was conducted to summarize the current state of knowledge of plastic pollution in Tanzanian aquatic systems. Although, Tanzania has vast coastlines and world’s largest freshwater lakes, the extent of microplastics presence in the aquatic environment remains largely unreported. Data from volunteer beach cleanups in Dar es Salaam areas …

A Key Note On Performance Of Smoothing Parameterizations In Kernel Density Estimation, Israel U. Siloko, Osayomore Ikpotokin, Edith A. Siloko

Tanzania Journal of Science

The univariate kernel density estimator requires one smoothing parameter while the bivariate and other higher dimensional kernel density estimatorsdemand more than one smoothing parameter depending on the form of smoothing parameterizations used. The smoothing parameters of the higher dimensional kernels are presented in a matrix form called the smoothing matrix. The two forms of parameterizations frequently used in higher dimensional kernel estimators are diagonal or constrained parameterization and full or unconstrained parameterization. While thefull parameterization has no restrictions, the diagonal hassome form of restrictions.Thestudyinvestigates the performance of smoothing parameterizations of bivariate kernel estimator using asymptotic mean integrated squared error aserror …

Sixty-sixpercentage (66%) of the faecal samples were positive for gastrointestinal parasites while 7% had mixed infections, 27% were negative for the parasites. Higher proportions of the faecal samples were positive for gastrointestinal parasites in Arusha and Rukwa compared to Katavi (p< 0.0001). The prevalence of Ancylostomacaninum(49%) was higher compared to that of other parasites (p <0.0001). Prevalence of A. lumbricoideswas significantly higher compared to that of E. granulosusand S. stercoralis(p = 0.0046). There was a positive association between parasite positivity rates and collecting dog’s faecal samples near domestic animals (p < 0.00001). Parasite diversity was higher in stray dogs from Katavi and Arusha (p > 0.05). There was no association between …
