Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

We thoroughly study a novel but basic combinatorial matrix completion problem: Given binary incomplete matrix, fill in the missing entries so that every pair of rows resulting has Hamming distance within specified range. obtain an almost complete picture complexity landscape regarding constraints and maximum number any row. develop polynomial-time algorithms for diameter three based on Deza's t...

a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...

Though more diicult to program, distributed-memory parallel machines provide greater scalability than their shared-memory counterparts. Distributed Shared Memory (DSM) systems provide the abstraction of shared memory on a distributed machine. While DSMs provide an attractive programming model, they currently can not eeciently support all classes of scientiic applications. One such class are tho...

Abstract The article presents the results of laboratory-field tests a working body that creates an artificial pipe for irrigation cotton with row spacing 60 cm from under soil. As evaluation criteria, water flow distance and moisture dispersion were taken inside formed without spilling onto field surface. When using this body, it was found dense walls soil low energy consumption, observed long ...

Seven new species of the genus Spinitectus Fourment, 1883, recovered from several species of freshwater fishes from West and Central Africa, are described. The eighth species, Spinitectus allaeri Campana-Rouget, 1961 recorded by Moravec (1974) in Egypt, is assigned to Spinitectus moraveci n. sp. The new and known species have been divided into three groups according to the number of spines in t...
