manual planting of sugar-beet stecklings is a very laborious and time-consuming opera-tion. to overcome the problems, and decrease the cost of operation to a reasonable level, a semi-automatic steckling transplanter was designed. the suitability of the steckling trans-planter with regard to the agrotechnical requirements of sugar-beet stecklings was stud-ied and the main field performance param...

in this paper using strongly duplexes we introduce a new class of (semi)hypergroups. the associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. two computer programs written in matlab show that the two groups $z_{2n}$ and $z_{n}times z_{2}$ produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.

this study was conducted to determine the prevalence and effect of parasitic infection on erythrocyte indices in trade camels slaughtered in maiduguri, nigeria. two hundred adult one humped camels comprised of 87 (43.5 %) males and 113 (56.5 %) females were examined for helminths and hemoparasites at their slaughter time according to the standard procedures. an overall prevalence of 79 % for si...

In this note we prove an explicit formula for the lower semicontinuous envelope of some functionals defined on real polyhedral chains. More precisely, denoting by H : R → [0,∞) an even, subadditive, and lower semicontinuous function with H(0) = 0, and by ΦH the functional induced by H on polyhedral m-chains, namely
