In ret: 1 the analyticity of the pressure in the dipole gas was proved by a somewhat indirect method, i.e., by methods not based on a direct C" bound on the nth order coefficient of the Mayer expansion. On the other hand, recently success has been met in finding direct C" bounds on the nth-order coefficient of the Mayer series for the twodimensional Yukawa gas in the region fie(0, 6~z) [here fl...

Cryotherapy, a technique extensively used in retinal surgery during the past few years, is claimed to be a safer procedure than diathermy and photocoagulation (Kirkconnell and Rubin, I965; Curtin, Fujino, and Norton, I966; Lincoff and McLean, I966; McDonald and Tasman, I967), but occasional complications have been described (Burch and Morse, I968; Shea, I968). The present report records the occ...

frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...

Formation of nano/ultrafine grain structure in AISI 304L austenitic stainless steel through the martensite reversion treatment was studied. The solution annealed specimens were cold rolled up to 95 % thickness reduction at -15°C. The cold-rolled specimens were subjected to reversion annealing treatment at the temperature range of 700-1000 °C for 10–150 min. Microstructural evolutions were analy...

One of the most effective ways to propagate Lilium is by using tissue culture techniques, preferably through bulblet production. In addition to the surviving percentage of Lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing Lilium micropropagation. Different concentratio...

Poa genus has a high value for grazing and forage conservation concerning thelivestock. In order to study the impacts of cold temperature and Growing Degree Days(GDD) on seedling morphological trait and phonological development of two speciesinvolving Poa pratensis and Poa trivialis, this research was conducted in laboratory andgreenhouse and outdoor of Research Institute of Forest and Rangelan...
