2014 Tunneling spectroscopy at high bias has proved to be useful as a tool for studying electronic excitations in junctions although one major difficulty encountered is the huge background in the second derivative of the tunneling characteristics I(V). This background however depends on which second derivative is used. We compare the sensitivity of the functions d2V/dI2, d2I/dV2 and 1/03C3.d03C...
An in vitro preparation of rabbit cornea was used to compare anatomical specialization and electrophysiological responses of A delta and C fiber sensory afferents which terminate as free nerve endings. Living nerve endings were visualized using epifluorescence microscopy and the vital dye 4-di2-ASP, and response properties were determined using microstimulation and recording of fiber discharge ...
Di(2-ethylhexyl) phthalate (DEHP), as a widespread environmental pollutant and an endocrine disruptor, can disturb the homeostasis of thyroid hormones (THs). In order to elucidate roles of the MAPK and PI3K/Akt pathways and hepatic enzymes in thyroid-disrupting effects of DEHP, Sprague-Dawley rats were dosed with DEHP by gavage for 30 consecutive days; Nthy-ori 3-1 cells were treated with DEHP ...
The rough relational database model was developed for the management of uncertainty in relational databases. A particular type of knowledge discovery, attribute oriented induction of rules from generalized data is described in this paper. Rough Relational Databases In rough sets (Pawlak 1984) an approximation space is defined on some universe U by defining some equivalence relation that partiti...
BACKGROUND AND OBJECTIVES One to two per cent of patients in need of red cell transfusion carry irregular antibodies to red blood cell (RBC) antigens and have to be supplied with specially selected blood units. To be able to respond to those requests, blood centres have to screen a significant number of donors for a variety of antigens serologically, which is a costly and through the shortage o...
A recently reported solution for stationary stability of a thermosolutal system with Soret diffusion is re-derived and examined using a symbolic computational package. Symbolic computational languages are well suited for such an analysis and facilitate a pragmatic approach that is adaptable to similar problems. Linearization of the equations, normal mode analysis, and extraction of the final so...
Those who use SAS Proc Lifetest know that it performs the two best known non-parametric tests to compare survival distributions – the Log Rank Test and the Wilcoxon-Gehan Test. In fact, however, these two tests are actually two members of a large class of linear rank tests. These tests are all equally valid, but will have different power. The specific linear rank test having greatest power wil...
Abstract Environmental adaptation of deciduous fruit trees largely depends on their ability to synchronize growth and development with seasonal climate change. Winter dormancy flower buds is a key process prevent frost damage ensure reproductive success. Temperature crucial environmental stimulus influencing the timing flowering, only occurring after fulfillment certain temperature requirements...
به منظور بررسی تاثیرکم آبیاری بر ویژگی های کمّی و کیفی سه رقم ماش، آزمایشی بصورت کرت های خرد شده در قالب طرح بلوک های کامل تصادفی با چهار تکرار در مزرعه تحقیقاتی پژوهشکده کشاورزی دانشگاه زابل واقع در شهرستان زهک اجرا شد. تیمارهای آزمایش شامل چهار سطح آبیاری di1) آبیاری بر اساس 45 درصد تخلیه رطوبت قابل استفاده خاک در کل دوره رشد( شاهد) di2) آبیاری بر اساس 70 درصد تخلیه رطوبت قابل استفاده خاک در ک...
کمبود آب شیرین، پیشروی آب شور دریاها و متعاقب آن شور شدن خاک زراعی از تهدیدهای اساسی برای بقاء تمدن بشری و اکوسیستم طبیعی به شمار می رود. به منظور بررسی اثرات شوری و مقایسه روش های کم-آبیاری (di) و آبیاری ناقص ریشه (prd)، بر خصوصیات فیزیکی ریشه گیاه لوبیا چشم بلبلی از طریق اعمال استرس شوری، تحقیقی در گلخانه پژوهشی دانشگاه علوم کشاورزی و منابع طبیعی ساری در قالب طرح کاملا تصادفی با 3 تکرار و تحت...
