با توجه به اثر عوامل تصادفی مانند خرابی ماشین‌ها بر قدرت رقابتی سازمان‌های تولیدی، اهمیت برنامه‌ریزی تولید دوچندان شده است. لذا سیستم‌های تولیدی مستعد شکست برای مقابله این عدم قطعیت، پدید آمده‌اند. جهت حفظ سهم در بازار رقابت و افزایش بهره‌وری، صنعتی اسـتراتژی نگهداری تعمیرات به‌منظور کاهش نرخ قابلیت اطمینان روی آورده‌اند. ظرفیت تولید، فراهم­آوردن انعطاف‌پذیری بیشتر از رضایت‌مندی مشتری نظر کمیّت،...

The underlying dependence structure between two random variables can be described in manifold ways. This includes the examination of certain properties such as lower tail decreasingness (LTD), stochastic increasingness (SI) or total positivity order 2, latter usually considered for a copula (TP2) (if existent) its density (d-TP2). In present paper we investigate 2 copula's Markov kernel (MK-TP2...

TP2 was purified from rat testes employing a gentle method involving differential salt extraction of the sonication-resistant spermatid nuclei. The nucleic acid binding properties of TP2 were studied by fluorescence quenching, thermal denaturation, circular dichroism techniques and compared with those of TPl (Singh, J., and Rao, M. R. S. (1987) J. Biol. Chem. 262, 734740). The tyrosine fluoresc...

TP2 was purified from rat testes employing a gentle method involving differential salt extraction of the sonication-resistant spermatid nuclei. The nucleic acid binding properties of TP2 were studied by fluorescence quenching, thermal denaturation, circular dichroism techniques and compared with those of TP1 (Singh, J., and Rao, M. R. S. (1987) J. Biol. Chem. 262, 734-740). The tyrosine fluores...

Teopod 2 (Tp2) is a semidominant mutation of maize that prolongs the expression of juvenile vegetative traits, increases the total number of leaves produced by the shoot, and transforms reproductive structures into vegetative ones. Here, we show that Tp2 prolongs the duration of vegetative growth without prolonging the overall duration of shoot growth. Mutant shoots produce leaves at the same r...

Transition protein 2 (TP2), which is expressed during stages 12-15 of mammalian spermiogenesis, has been shown to undergo phosphorylation immediately after its synthesis. We reported earlier that TP2 is phosphorylated in vitro at threonine 101 and serine 109 by the salt extract of sonication-resistant (elongating and elongated) spermatid nuclei and the protein kinase phosphorylating TP2 was ide...

BACKGROUND We investigated the change of prognosis in resected gastric cancer (RGC) patients and the role of radical surgery and adjuvant chemotherapy. METHODS We retrospectively analyze the outcome of 426 consecutive patients from 1975 to 2002, divided into 2 time-periods (TP) cohort: Before 1990 (TP1, n = 207) and 1990 or after (TP2; n= 219). Partial gastrectomy and D1-lymphadenectomy was p...

Teopod1 and Teopod2 are dominant, unlinked mutations in maize that cause dramatic morphological abnormalities, including inappropriate expression of juvenile traits in adult vegetative phytomers and the transformation of reproductive structures into vegetative ones. These phenotypes are consistent with the constitutive expression of a juvenile phase of development throughout shoot growth. To in...

Eight patients with chronic open-angle glaucoma who had an intraocular pressure greater than 24 mm Hg at some time during the day while taking timolol 0.5% twice daily were given the fixed ratio combination of timolol 0.5% with pilocarpine 2% (TP2) twice daily. By comparing full 24-hour diurnal curves on timolol with those on TP2 it was possible to show that all patients except one (at a single...
