Abstract This paper examines the problem of computing a canonical smallest covering region for an arbitrary discrete probability distribution. optimisation is similar to classical 0–1 knapsack problem, but it involves over set that may be countably infinite, raising computational challenge makes non-trivial. To solve we present theorems giving useful conditions optimising and develop iterative ...

Despite significant progress, the general functional and evolutionary significance of the untranslated regions (UTRs) of eukaryotic transcripts remain mysterious. Particularly mysterious is the common occurrence of spliceosomal introns in transcript UTRs because UTR splicing is not necessary for restoration of transcript coding sequence. In general, it is not known to what extent such splicing ...

Solid waste management has been known to play an important role in public health and the environmental status of developing countries. Waste assessment can help researchers and governors in management programs and devising alternative plans in order to improve public health and economical savings. In the present study, statistical estimations regarding waste generation and type of solid wastes ...

Interest in arid ecosystems as a source of food supply for rapidly increasing population of the world, on the one hand, and the problems pertaining to the climatic characteristics, water shortages and soil sensitivity for the inhabitants in such areas, on the other have prompted efforts at both national and international levels to develop a better understanding of these problems as well as to f...

the loss of a child is a tragedy - families suffer and human potential is wasted. 6.3 million children under the age of five died in 2013, nearly 17 000 every day. most deaths among children aged one to five years are due to diseases that can be prevented, but that can also be easily treated at home or in health facilities. leading causes of death in under-five children are preterm birth compli...
