Martin Josefsson [1] has coined the term ‘bisect-diagonal quadrilateral’ for a quadrilateral with at least one diagonal bisected by other diagonal, and extensively explored some of its properties. This also been called ‘bisecting [2], ‘sloping-kite’ or ‘sliding-kite’ [3], ‘slant kite’ [4]. The purpose this paper is to explore more properties quadrilateral.

Off-diagonal parton distributions occur in several hard exclusive reactions. They extend the study of hadron structure beyond what can be learned from ordinary distributions and have a particularly rich spin structure. The hard scattering subprocesses in electroproduction of mesons and of real photons satisfy helicity selection rules, which provide powerful tools to test leading-twist dominance...

alzheimer’s disease (ad) is a uniquely human disorder. although the pathogenesis of ad is not fully understood, growing evidence indicates that the deposition of beta-amyloid (aβ) and the local reactions of various cell types to this protein play major roles in the development of the disease. in the present study transgenic mice expressing mutant amyloid precursor protein (app) has been used. t...

The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposi...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

In her dissertation, Angela Hicks showed that, to reduce the HMZ shuffle conjecture, it is sufficient to find a certain bijection between two sets of two-part parking functions which, roughly speaking, either swaps the two parts of the parking function or transfers a car from the second part to the first part and which satisfies certain nice properties. I will consider a special case where this...

Characterizations of zero-diagonal operators (i.e., operators that have a diagonal whose entries consist entirely of zeros) and the norm-closure of these operators are obtained. Also included are new characterizations of trace class operators, self-commutators of bounded operators, and others. 0. Introduction. In [3], it is shown that a hermitian compact operator is a self-commutator of a compa...

over a period of four years, we followed 200 male cases (female patients were excluded from this study because from early childhood, the majority of iranian girls have their ears pierced which tends to distort the ear lobe and renders the diagnosis of the crease difficult) of proved coronary artery disease (angina pectoris, coronary insufficiency, and myocardial infarction) in a private clinic ...
