In this study, three different age groups of male broodstocks (4, 5 and 6 years respectively) were used to fertilize eggs obtained from nine females. The results showed that 6 year old males had maximum body weight (1766 g), total length (56.3 cm) and sperm volume (31.83 ml). Results did not show significant difference in spermatocrit and spermatozoa concentration among age groups (p>0.05). Our...

Multiple mating allows females to obtain material (more sperm and nutrient) and/or genetic benefits. The genetic benefit models require sperm from different males to fertilize eggs competitively or the offspring be fathered by multiple males. To maximize genetic benefits from multiple mating, females have evolved strategies to prefer novel versus previous mates in their subsequent matings. Howe...

The classification of soils originated from three main sources: from early empirical soil surveys, from folk soil classifications and from scientific theory of pedology. The first soil classifications reflected their origin in different extent, and still remain certain features of their initial sources. The actual situation in soil classification is discouraging, mainly due to the diversity of ...

Abstract Fertilization was doing to measure the success of sperm cryopreservation because it more informative. Sperm expected get that successfully fertilize egg well. The aim this study determine fertilization ability giant grouper (Epinephelus lanceolatus, Bloch 1790) 48 hours post-cryopreservation in fertilizing tiger eggs fuscoguttatus, Forskal 1775). carried out artificially using with 6% ...

جمعیت رو به افزایش انسانی برای امرار معاش، اثرات زیادی بر منابع طبیعی می گذارد. از این تغییرات می توان، تغییر کاربری و پوشش زمین را نام برد که نهایتاً منجر به کاهش سطح نواحی زیر پوشش گیاهان طبیعی می شود. دشت سیرجان با داشتن رژیم حرارتی ورژیم رطوبتی به ترتیب ترمیک و اریدیک نیز از اعمال این گونه تغییرات مصون نمانده است و مساحت زیادی از زمین های با پوشش گیاهی طبیعی(مراتع) به باغات پسته تبدیل شده ان...

نفت استخراج شده در اکثر میادین نفتی حاوی مقادیری آب به شکل امولسیون می باشد که انواعی از نمک ها به صورت نامحلول، در قطرات آب پراکنده شده در نفت وجود دارند. این امولسیون ها، به دلیل حمل آب اضافی و بالاتر بودن ویسکوزیته، باعث افزایش هزینه های حمل و نقل و پمپ کردن می شوند. همچنین نمک های حل شده در قطرات آب باعث افزایش مشکلات خوردگی تجهیزات و غیر فعال شدن کاتالیست ها می گردد. بنابراین شکستن امولسی...

In a finite system driven out of equilibrium by constant external force the thermodynamic uncertainty relation (TUR) bounds variance conjugate current variable cost maintaining non-equilibrium stationary state. Here we highlight new facet TUR showing that it also time-scale on which can exhibit anomalous kinetics. particular, demonstrate subdiffusion in single file confined to ring as well drag...

Recycling nutrients in municipal sewage sludge (MSS) to soil would support sustainable development. In this study, a comprehensive recycling using specific plants able grow the fresh MSS and an indirect application technique was developed. Fresh placed permeable containers next Handroanthus chrysanthus provide fertilization. Sludge treatment ( Alocasia macrorrhiza Pennisetum hybridum ) were gro...
