Calibration Of Hdm-4 For Use In Pavement Management Systems (Pms), Nurdin Mushule

Tanzania Journal of Engineering and Technology (TJET)

One of major problems of road management in developing countries is the lack of decision making tools for preparing road maintenance programmes. This results in poor resource allocation and poor utilisation of existing assets. Pavement management systems (PMS) have been developed around the world in order to assist with the pavement management process in a co-ordinated and systematic manner. Some developed countries have derived pavement performance models that are suited to local conditions by setting up long term pavement performance studies. Conversely, most developing countries do not have the resources required to set up similar large-scale field experiments. However, validation …

The Influence Of Branches In The Performance Of Power-Line Communication Systems That Use Mc-Coma With Reed Solomon Coding, Emmanuel Felix

Tanzania Journal of Engineering and Technology (TJET)

Power-line network is proposed as an infrastructure for Information and Communications Technologies (ICTs)
services provision. However, there are a number of factors that contribute greatly to power-line communication performance degradation. These include number of branches that can be added or removed from the power- line network, lengths of the branch lines, loading etc. It has been pointed out that the number of branches is one of the factors that affects power-line performance to a certain extent. In this paper the influence of number of branches on the performance of Broadband Power-line communication (BPLC) that uses MC- CDMA modulation scheme with …

Sustainability Of Business Development Services: Gaps Analysis Of The Kenyan Market, Hellen Otieno, Donath Olomi, Ruth Kiraka

Business Management Review

A key challenge in entrepreneurship and private sector development is the provision of sustainable Business Development Services (BDS), particularly for micro and small enterprises. This study investigates how sustainability of BDS can be achieved, and how some providers manage to develop sustainable BDS and not others, using Grounded Theory. The findings suggest that there are at least nine specific demand-and-supply-side gaps in the BDS market which providers need to identify and fill if they are to become sustainable. The gaps relate to awareness, value, trust, quality, capacity, unwillingness to pay, appreciation, inability to pay and perception. How providers identify and …

A Phylogenetic Study Of The Old World Asclepiadinae (Apocynaceae) Based On Chloroplast And Nuclear Dna Sequence Data, David Chuba

Dissertations and Theses

Relationships within the African Asclepias generic complex (Asclepiadinae, Apocynaceae) have for a long time been only a matter of intuitive speculation and generic delimitations have been diverse and rather contentious. Generic delimitation in this group has been based on morphological characters that are usually not exclusive to any particular clade or genus. The difficulty of identifying taxonomically useful morphological characters for inferring generic delimitations has led to differences in the emphasized characters by different taxonomists. This study is aimed at understanding phylogenetic relationships of species within the African Asclepias complex based upon the nuclear PgiC and three chloroplast DNA regions, …

A Study Of The East African Slave Trade In Bagamoyo, Jake Salyers

Independent Study Project (ISP) Collection

The purpose of my study was to learn about the east African Slave trade and its relationship to the town of Bagamoyo. Bagamoyo was an important trading town on the coast of Tanzania during the peak of the Arab run slave and ivory trade. Slavery was only abolished in Tanganyika in 1922, so there are still many monuments and memories remaining in the town concerning the slave trade. I had two main methods of collecting information about the town, interviewing the descendants of slaves and slave owners and researching the history of Bagamoyo. I was able to get three different …

Deep Ecology And End-Of-Life Care, Paul Carrick

Philosophy Faculty Publications

Physicians and nurses caring for terminally ill patients are expected to center their moral concerns almost exclusively on the needs and welfare of the dying patient and the patients family. But what about the relationship of traditional medical ethics to the emerging new theories of environmental ethics, like deep ecology? As we glide into the twenty-first century, can anyone seriously doubt that the mounting global concerns of environmental ethics will eventually influence the ethics of medicine too?

For example, suppose physicians were to integrate the core values of an ecocentric environmental ethic like deep ecology into contemporary North American norms …

Serotonin Immunoreactive Cells And Nerve Fibers In The Mucosa Of The Rat Stomach, A P Gesase

Tanzania Journal of Science

The current study has showed the morphological features of serotonin (5-hydroxytryptamine) immunoreactivity in the pyloric mucosa of the rat stomach. The immunoreactive elements included the endocrine cells, mast cells and mucosal nerve fibers in the lamina propria. The immunopositive endocrine cells were oval in shape and located mostly in the basal part of the gastric glands. The cell contained a central non-staining area and the peripheral staining zone. The mast cells stained homogenously and appeared to be oval-round in shape. They were located in the upper, middle and basal parts of the mucosa. Serotonin immunoreactive nerve fibers with varicosities were …
