Isolates (49) of escherichia coli were isolated from 100 samples of mutton collected from dressed sheep carcasses by excision method. The isolates were typed into 12 different ‘O’ serogroups. The most frequent serovar isolated was O101, followed by O152, O76, O23, O139, O88, O110, O126, O8, O9, O15 and O133; two isolates were untypable while one was rough. All the isolates of escherichia coli w...

In this study, we explore factors that determine citizens’ tax compliance attitude in Kenya, Tanzania, Uganda and South Africa. The analysis is based on attitude and perception data from the new round of Afrobarometer surveys, which contain more tax-specific information than previous rounds. Using binary logit regression, we find some similarities, but also differences in factors that are corre...

To an integral lattice L in the euclidean space (R, (, )), one associates the set of characteristic vectors v ∈ R with (v, x) ≡ (x, x) mod 2Z for all x ∈ L. They form a coset modulo 2L, where L = {v ∈ R | (v, x) ∈ Z ∀x ∈ L} is the dual lattice of L. Recall that L is called integral, if L ⊂ L and unimodular, if L = L. For a unimodular lattice, the square length of a characteristic vector is cong...

Shiga-toxigenic Escherichia coli (STEC) strains cause serious gastrointestinal disease, which can lead to potentially life-threatening systemic complications such as hemolytic-uremic syndrome. Although the production of Shiga toxin has been considered to be the main virulence trait of STEC for many years, the capacity to colonize the host intestinal epithelium is a crucial step in pathogenesis....

This paper focuses on the macroeconomic management of large inflows of foreign aid. It investigates the extent to which African countries have coordinated fiscal and macroeconomic responses to aid surges. In practice, we construct a panel dataset to investigate the level of aid ‘absorption’ and ‘spending’. This paper departs from the recent empirical literature by utilising better measures for ...

A procedure is described for the selection of glucose uptake mutants based upon radiation suicide of Chinese hamster fibroblasts by 2-deoxy[3H]glucose. In one of these mutants, DS 7, the ability to transport either 2-deoxyglucose or 3-O-methylglucose was decreased to one-fifth to one-fourth. Besides this defect, DS7 produces 1/14th the lactic acid produced by the parent when grown on 5 mM gluco...

although the majority of the patients with traumatic brain injury presents with injuries involving the extremities, there was a clear paucity of adequate experimental polytrauma models. to close this gap, we conducted several studies to establish two different polytrauma mice models including both closed and open traumatic brain injury. male c57bl mices with a mean weight of 23g were anesthetiz...
