We present a comprehensive study of pattern formation in single-field relaxational systems with field-dependent coefficients. A modulated mean-field theory leads to a form amenable to analysis via the geometric architecture developed in our earlier work for systems that exhibit phase transitions between global steady states [Phys. Rev. E 69, 011102 (2004)]. We demonstrate that the phase diagram...

the cotton leaf roller moth, haritalodes derogata (fabricius, 1775) (lepidoptera: crambidae) was collected on two kinds of flowering shrubs, hibiscus syriacus l. and hibiscus mutabilis l., in rasht, guilan province, during august 2013. this species represents a generic new record for the fauna of iran. a brief description of the species is provided to facilitate the identification.

calving records from april 1996 to december 2005 comprising 31863 calving events of 1173 dairy cows in a large commercial dairy herd were used to evaluate the effects of heat stress, using temperature-humidity index (thi) on milk yield and composition and reproductive performance of holstein dairy cows under humid climatic conditions of rasht in iran. thi values were grouped into six groups: 30...

background: methadone is considered a long-acting opioid agonist which is widely used in the treatment of drug addiction. it is believed that opioids can cause erectile dysfunction (ed) by inhibiting gonadotropin and testosterone release. this study is aimed at defining the possible effects of conservative treatment with methadone on erectile dysfunction in the addicts. methods: a total of 382 ...

leptospirosis is a zoonosis of worldwide distribution, caused by leptospira interrogans and is considered as an emerging global public health problem. transmission usually results from direct or indirect exposure to the urine or other body fluids of leptospiruric animals which may become a source of infection for human or other animals. having a humid climate with plenty of annual rainfall, gui...

In order to calibrate and validate the PILOTE model for rice in a humid climate, this study was carried in a randomized complete block design with three replications on a popular local variety, Hashemi, during 2001, 2002, 2005, 2006 and 2007 crop seasons. This research was done at the Rice Research Institute of Rasht, Iran. Evaluation of simulated and measured grain yield and dry matter values ...
