ARC (accumulation and replication of chloroplasts) genes control different aspects of the chloroplast division process in higher plants. In order to establish the hierarchy of the ARC genes in the chloroplast division process and to provide evidence for their specific roles, double mutants were constructed between arc11, arc6, arc5, arc3 and arc1 in all combinations and phenotypically analysed....

An acyclic coloring of a graph G is an assignment of colors to the vertices of G such that no two adjacent vertices receive the same color and every cycle in G has vertices of at least three different colors. An acyclic k-coloring of G is an acyclic coloring of G with at most k colors. It is NP-complete to decide whether a planar graph G with maximum degree four admits an acyclic 3-coloring [1]...

In this note we give examples of division rings which posses an anti-automorphism but no involution. The motivation for such examples comes from geometry. If D is a division ring and V a finite-dimensional right D-vector space of dimension ≥ 3, then the projective geometry P(V ) has a duality (resp. polarity) if and only if D has an anti-automorphism (resp. involution) [2, p. 97, p. 111]. Thus,...

the present article attempts to investigate the relationship between women's social capital and household tasks division in the family. first, a review of literature and the related theories have been provided. this article has studied a sample of 400 married women in jiroft for the household work division in their family according to the social capital theory. to collect the data, the quantita...

background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...

During development, all cells make the decision to live or die. Although the molecular mechanisms that execute the apoptotic program are well defined, less is known about how cells decide whether to live or die. In C. elegans, this decision is linked to how cells divide asymmetrically [1, 2]. Several classes of molecules are known to regulate asymmetric cell divisions in metazoans, yet these mo...

In this paper we consider the problem of chore division, which is closely related to a classical question, due to Steinhaus [7], of how to cut a cake fairly. We focus on constructive solutions, i.e., those obtained via a well-defined procedure or algorithm. Among the many notions of fairness is envy-freeness: an envy-free cake division is a set of cuts and an allocation of the pieces that gives...
