Height, weight, body mass index and learning achievement in Kumi district, East of Uganda

  The objective was to determine the relationship between nutritional status as measured by height-for-age, weight-for-age, body mass index for age (BMI for-age)and learning achievement. A descriptive cross-sectional design was used. The study was conducted in 34 elementary schools in the district of Kumi, east of Uganda. The subjects included a random selection of 1003 children (457 boys and 546 girls) of...

Drought - inducible genes and differentially expressed sequence tags associated with components of drought tolerance in durum wheat

  Drought stress is one of the most important environmental factors reducing cereal yields. The genetic and physiological bases of drought tolerance in durum wheat was investigated by QTL mapping and by mapping candidate genes derived from differentially expressed genes and previous investigations. A recombinant inbred population derived from a cross between two durum (Triticum turgidum L. var durum)...

Plasmid-borne antibiotics resistant markers of Serratia marcescens: an increased prevalence in HIV/AIDS patients

  This study  was  carried  out  to  evaluate  the  resistant  pattern  of  multi-drug resistant strains of Serratia marcescens associated with HIV/AIDS infected individuals in Nigeria. A total 1709 samples (1323 urine and 406 diarrhea stool) were collected from individuals living with HIV/AIDS over a three year period and screened for...

Effect of temperature on the attack of fluorapatite by a phosphoric acid solution

  The attack of fluorapatite (Fap) by phosphoric acid solution between 25 and 65°C was followed by microcalorimetry. The molar enthalpy decreases until a temperature close to 45°C, and then increases. This behaviour was attributed to a change of mechanism. Iteration of the results enables us to propose a two or one step mechanism, depending on the temperature range. Kinetic and thermochemical parameters...
