We study the non-negativity conjecture of the complete cd-index of a Bruhat interval as defined by Billera and Brenti. For each cd-monomial M we construct a set of paths, such that if a “flip condition” is satisfied, then the number of these paths is the coefficient of the monomial M in the complete cd-index. When the monomial contains at most one d, then the condition follows from Dyer’s proof...

An experiment was conducted at the Research farm of Regional Agricultural Research Station, BARI, Hathazari, Chittagong during Rabi season (December to April), 2009-2010 for estimation of genetic variability, genetic parameters and correlation coefficient among different yield components in a randomized block design with three replications. Thirty four groundnut genotypes were tested in the exp...

Sub-Saharan Africa has the least mechanized agriculture in world due to various reasons including low effective demand at farm level, policy attention, and ineffective mechanization strategies. However, situation changed since recently favor of while limited empirical evidence is available on how can be enhanced among smallholder farmers. In this study, we explore farmers' willingness invest se...

AIM To analyze clinical course of war-related injuries in children treated at the Split University Hospital during the wars in Croatia (1991-1995) and Bosnia and Herzegovina (1992-1995). METHODS Medical records of 94 treated children were analyzed. The severity of wounds was scored according to the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) evaluation systems. RESULTS Mo...

although the shelling and bombing against the residential areas have been prohibited in the international law, the iraqi regime used these tools frequently to advance its military and political strategy. these attacks were escalated after the kheibar operation. this article considers the definitions and concepts of the war of the cities and then studies the trend of this war during the iran-ira...

The quality of walnuts deteriorates owing to the poor shelling equipment. improvement is urgently required for walnut processing. In this study, systematic research was carried out on changes in mechanical properties, model shelling, and key parameters were determined as angles conic roller (X1), speeds (X2), clearance between static (X3), moisture content (X4). Box–Behnken design method used e...
