We consider the fuzzification of the notion of fuzzy multiply positive implicative hyper BCK-ideals of BCK-algebras and then some related results are obtained. Using the concept of level subsets, we give a characterization of a fuzzy multiply positive implicative hyper BCK-ideal. We state a relation between a fuzzy hyper BCK-ideal and a fuzzymultiply positive implicative hyper BCK-ideal. Moreov...

One of the annual issues that has to be addressed in English football is producing a fixture schedule for the holiday periods that reduces the travel distance for the fans and players. This problem can be seen as a minimisation problem which must abide to the constraints set by the Football Association. In this study, the performance of selection hyper-heuristics is investigated as a solution m...

background: hyper ige syndrome (hies) is a rare primary immune deficiency, described as job`s syndrome characterized by increased serum levels of ige, eczema, recurrent cutaneous and pulmonary infections. in this paper, we presented a case of hyper ige syndrome.case presentation: a 16-year-old iranian boy presented with a one year history of skin lesions in knees and elbows was diagnosed of pso...

the influence of hypo- and hyper-thyroidism on spermatogenesis was studied in 60-day-old adult malewistar rats. to confirm hypo- and hyper-thyroidism, the concentration of plasma thyroid hormones wereassayed by radioimmunoassay. the hypothyroid state, induced by administration of 25 mg/kg/daymethimazole for 5 successive days, resulted in significant decrease in the number of sertoli cells, sper...

Cardiac microvascular rarefaction appears to be involved in hyperthyroidism-induced left ventricular hypertrophy and dysfunction. We investigated the effects of losartan, an AT1 receptor antagonist; diltiazem, a calcium channel blocker; and propranolol, a β-adrenergic receptor antagonist, on cardiac function and structural microcirculatory cardiac alterations in an experimental model of l-thyro...

he coexistence of thyroid and parathyroid diseases is not rare. In the review of the recent literature, 25% of the patients with primary hyperparathyroidism (PHPT) had significant associated thyroid diseases including carcinoma in an Australian series.1 Regal et al,2 reported a high prevalence of unsuspected varieties of thyroid disease occurring mainly in postmenopausal women in patients with ...

The Hyper-Flute is a standard Boehm flute (the model used is a Powell 2100, made in Boston) extended via electronic sensors that link it to a computer, enabling control of digital sound processing parameters while performing. The instrument’s electronic extensions are described in some detail, and performance applications are briefly discussed.

in this paper, the goursat problem of a third order equation on cases of explicit solvability isinvestigated, with the help of the riemann function. some results and one theorem are given concerning theexistence and uniqueness for the solution of the suggested problem.
