THE Sudan is one of the largest African countries with an area of about 2.5 million km2 and 18.5 million people. It is a predominantly agricultural country with a large development potential, especially in agriCUlture and livestock production. Its estimated agricultural land is more than 800 million ha although at present only about 7 million ha are under cultivation. Of the latter, only 1.6 mi...

This research was conducted to investigate in situ degradation characteristics of maize, sorghum and sorghum-Sudan grass hybrids. whole plant of maize (TTM-815, DK-711), sorghum (SS-506, FS-5) and sorghum × Sudan grass hybrids (P-988, Grazer N2) were grown under semi-arid conditions and harvested at different maturity stages (mid-flowering (MF), milk-line (ML) and hard-dough (HD)) and ensiled. ...

We have developed a simple, convenient and inexpensive voltammetric method for determining trace Sudan I contamination in chili powder, based on the catalyzed electrochemical reduction of Sudan I at the carbon nanotube modified electrode. Under optimized conditions, the method exhibited acceptable analytical performance in terms of linearity (over the concentration range 6.0×10-7 to 7.5×10-5 M,...

In general, STIs are epidemics and present an enormous health and economic cosequences. An estimated half a billion new cases of STIs occur each year globally, with women being more susceptible and bearing the greatest burden of these infections. Sudan geographically is bounded by nine countries most of them have a high prevalence of HIV seropositive. Currently, the HIV seropositive prevalence ...

Iodine Deficiency Disorders (IDD) Control Programme in Sudan adopted salt iodization as the long-term strategy in 1994. In 2000, it was found that less than 1% of households were using adequately-iodized salt. The objectives of this study were to: (i) study the coverage and variation of different geographical regions of Sudan regarding access to and use of iodized salt, (ii) explore the possibl...

This paper describes a novel electrochemical method for the determination of Sudan I in food samples based on the electrochemical catalytic activity of graphene modified glassy carbon electrode (GMGCE) and the enhancement effect of an anionic surfactant: sodium dodecyl sulphonate (SDS). Using pH 6.0 phosphate buffer solution (PBS) as supporting electrolyte and in the presence of 1.5 × 10(-4)mol...

Sudan I is a carcinogenic compound containing an azo group that has been illegally utilized as an adulterant in food products to impart a bright red color to foods. In this paper, we develop a facile lab-on-a-chip device for instant, ultra-sensitive detection of Sudan I from real food samples using plasmonics-enhanced diatomaceous thin film, which can simultaneously perform on-chip separation u...

Background In Sudan, where studies on HIV dynamics are few, model projections provide an additional source of information for policy-makers to identify data collection priorities and develop prevention programs. In this study, we aimed to estimate the distribution of new HIV infections by mode of exposure and to identify populations...

Human immunodeficiency virus (HIV) was the fourth leading cause of death worldwide, 33 million people were estimated to be affected for life, approximately two third of them are African [1]. Sudan is bordered by countries with high rates of HIV infection, and the first AIDS case was reported in 1986 [2]. A behavioral and epidemiological survey (BES) was conducted by Sudan National AIDS Program ...
