In this paper, the notion of direct sum of branches in hks is introduced and some related properties are investigated. Applying this notion to lower hyper $BCK$-semi lattice, a necessary condition for a hi to be prime is given. Some properties of hkc are studied. It is proved that if $H$ is a hkc and $[a)$ is finite for any $ain H$, then $mid Aut(H)mid=1$.

background: to evaluate the intermediate-term outcomes of radius shortening as a treatment for kienbock’s disease. materials and methods: in a historical cohort, 16 skeletally mature patients (9 men and 7 women) with kienbock disease, who were treated with radial shortening osteotomy between 2002 and 2012, were reviewed in our study. the mean age of our patients was 30 (range 18-43) years old. ...

Objective(s): Long-term, irregular endurance exercise may result in disturbance to the angiogenesis of heart muscles and blood supply. The aim of the present study is to evaluate the effects of mid- and long-term endurance exercise on the process of angiogenesis.Materials and Methods: Eighteen male Wister rats of 220±10 g, were randomly assigned to three groups of 6 rats including: Control, Mid...

conclusions the mechanism of mid-variant of dobutamine-induced stress cardiomyopathy remains unclear. we think that multiple mechanisms are involved and this risk should be considered in patients with comorbid psychiatric conditions and with use of centrally acting stimulants. case presentation we report a 48-year-old female with intermittent chest pain. her physical exam, cardiac enzymes and t...

Sustainability of rice production under limited water conditions is threatened by increasing irrigation water scarcity. Therefore, physiological and morphological responses of rice to varying water stress management strategies should be determined. The physiological and morphological responses of a semi dwarf rice (Hashemi cultivar) to water stress intensities (mild and severe, i.e., short-dura...

This study investigated the effect of Narrow Reading (NR) on learning mid-frequency words. Vocabulary Size Test (VST) designed by Nation and Beglar (2007) was administered as the first pre-test to 196 students, from among whom 91 students whose vocabulary size ranged between 2100- 3500-word families, , became the target of this study and were randomly c...
