although believing in the reappearance of imam mahdi is an islamic belief, it has an outstanding position in the shiite school. it can be said the main proof behind this position is that shiites have accepted his birth and life. regardless of the foundations and arguments of shiites, some sunni writers have sharply opposed this belief. ahmad b. taymiyya is one of these writers who has made cert...

petri disease is responsible for grapevine decline and occurs wherever grapevines (vitis vinifera) are cultivated. phaeoacremonium species are among the principal hyphomycetes associated with petri disease. during 2009, a field survey was conducted throughout different vineyards in the fars province of iran in order to determine the fungal pathogens associated with the vine decline observed in ...

since the beginning of the presence of the holy qur’an, criticism and rhetoric have received attention in the areas of culture and thought, too. in this respect we can name some literary and rhetorical works like maj?z al-qur’?n by abu ubaydah ma’mar ibn muthann?, ket?b al-fas?hah by abu h?tam sajest?ni, e’j?z al-qur’?n by j?hez basri, naqd al-nathr wa naqd al-she’r by abu al-faraj qud?mah ibn ...

Thioredoxins (Trxs) are small ubiquitous disulfide reductases that participate in dithiol-disulfide exchange reactions. In contrast to animals and prokaryotes that typically possess one or a few genes encoding Trxs, higher plants contain eight different Trx types: f, m, x, y, z, o, s, and h. Trx h with multiple forms is involved in different processes such as seed germination, cellular protecti...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

0. Introduction A number of mathematical techniques have been applied for solving nonlinear problems. Energy Balance [1–3], homotopy analysis [4], variational iteration [5], homotopy perturbation [6,7], the max–min approach [8,9], frequency amplitude formulation [10] and perturbation methods [11] are the most prominent approaches that those have been employed for solving a large number of nonli...
