The drying kinetics of kale (Brassica oleracea) in a convective hot air dryer
(Elsevier, 2005-12-31)
The effect of air temperature and sample thickness on the drying kinetics of kale was investigated using a convective air dryer at a fixed airflow rate of 1 m/s and drying air temperatures of 30, 40, 50 and 60 °C. The ...
Research trends in modeling, optimization and control of the drying operation
(2007)
Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ...
Physical changes during coffee roasting in Rotary Conduction‐Type Heating Units
(Blackwell Publishing Ltd, 2003-08-23)
Coffee beans were roasted in a rotary conduction-type-heating unit under constant heating surface or product temperatures ranging from 200 to 240C or 170 to 210C, respectively. the roasting duration was varied from 0 to ...
Analysis of genetic diversity in Eucalyptus grandis (Hill ex Maiden) seed sources using inter simple sequence repeats (ISSR) molecular markers
(Academic Journals, 2008-07-04)
Eucalyptus grandis is an economically important tree species that is native to the Australian continent and its northern neighbours, where it is grown primarily for its hard wood timber and pulp for paper industries. It ...
Uncovering the tracks of a recent and rapid invasion: the case of the fruit fly pest Bactrocera invadens in Africa.
(Blackwell Publishing Ltd, 2009-09-10)
Phytophagous insects of the genus Bactrocera are among the most economically
important invasive fruit fly pests. In 2003, an unknown Bactrocera species was found
in Kenya. First identified as an ‘aberrant form’ of the ...
Expression of metallothionein and tubulin in heavy metal-tolerant Anopheles gambiae sensu stricto (Diptera:Culicidae).
(Elsevier, 2010)
Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats.
In this study we explored the possibility of using Anopheles gambiae sensu stricto as bioreporters for environmental heavy metal ...
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2007-12)
Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies (Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number of factors have been implicated in the transformation ...
Urinary soluble egg antigen levels in Schistosoma haematobium infection in relation to sex and age of Kenyan schoolchildren following praziquantel treatment
(2009-08)
Schistosoma haematobium soluble egg antigen (SEA) secreted in urine can be assayed to determine egg tissue load and hence morbidity in infected individuals. A cohort of 158 infected children aged 4-18 years was followed-up ...
Survey of sweet potato viruses in Western Kenya and detection of cucumber mosaic virus.
(2010)
Sweet potato is an important food crop worldwide, but several pests and diseases limit its
production. In eastern Africa, virus-induced diseases rank second to weevils in causing yield reduction. Symptomatic sweet potato ...
