A five-year-old dog was referred with a five-month history of lethargy, decreased appetite, cough and intermittent forelimb lameness. Radiographs revealed an intra-thoracic lesion and a marked periosteal bone apposition of the second digit on the left forelimb. As it was palisading and circumferential, the latter appeared typical of hypertrophic osteopathy (HO). A grass awn in a sub-lobar ramif...

The sessile nature of plants demands the development of seed-dispersal mechanisms to establish new growing loci. Dispersal strategies of many species involve drying of the dispersal unit, which induces directed contraction and movement based on changing environmental humidity. The majority of researched hygroscopic dispersal mechanisms are based on a bilayered structure. Here, we investigate th...

Two-dimensional electrophoresis (2-D PAGE) led to identification in the polypeptide maps of boar seminal plasma of four conserved polypeptides with identical molecular weight of 24 kDA, and different ranges of isoelectric point (pI): (1) 7.4-7.7, (2) 8.1-8.4, (3) 8.5-8.8 and (4) 9.2-9.4. In the current study the molecular structures of these polypeptides were analysed, for the first time, by ma...

Let Z and IR (C) denote the ring of the integers and the field of real (complex) numbers, respectively. For a field F, we put i* = F\{0}. Fix A GC and B G C*, and let X(A, B) consist of all those second-order recurrent sequences {wn}neZ of complex numbers satisfying the recursion: n+i = „ ~ n-i (i.e., Bwn_Y = Awn wn+l) for n = 0, ± 1, ± 2,.... (1) For sequences in SE(A,B), the corresponding cha...

Small RNAs (sRNA) of 15-30 nucleotides regulate various processes in eukaryotes. Regulatory sRNAs are produced through the RNA interference (RNAi) pathway from double stranded RNA (dsRNA). Dicer or dicer-like enzyme processes the dsRNAs into 15-30 bp dsRNAs, which in turn bind to the RNA-induced silencing complex (RISC) to regulate gene expression. We previously cloned sRNAs from barley. In thi...

In this paper, we present two contributions for Arabic Word Sense Disambiguation. In the first one, we propose to use both two external resources AWN and WN based on Term to Term Machine Translation System (MTS). The second contribution relates to the disambiguation strategies, it consists of choosing the nearest concept for the ambiguous terms, based on more relationships with different concep...

Two crosses of bread wheat viz., K 1006 x LOK 1 and PBW 343 HUW 234 were investigated to explore the useful variability parameters, correlation along with inheritance study (skewness kurtosis) in segregating F2 F3 population for yield its component traits respectively. Narrow difference between phenotype genotype coefficient variation showed less influence environment on expression under invest...
