reference evapotranspiration is an important parameter in irrigation systems' design that is evaluated through either direct (lysimeter) or calculated method (empirical equations). when there is a lack of lysimeters' data, penman monteith fao method could be employed as a standard method for evaluating the other empirical methods' results. in this research, 13 year evaporation pa...
اثرات حشره کشی و دورکنندگی عصاره گیاهان پنیر باد و علف مار بر tribolium confusum و sitophilus oryzae
در این تحقیق به منظور کاهش خسارت آفات و اثرات نامطلوب آفت کش ها در محصولات انباری اثرات حشره کشی و دور کنندگی عصاره متانولی و استونی میوه پنیر باد (withania coegulans) و علف مار(capparis spinosa) روی حشرات کامل شپشه آرد (tribolium confusum) و شپشه برنج (sitophilus oryzae) در دمای 1 ±27 درجه سانتی گراد و رطوبت نسبی 5±65 درصد و در تاریکی مورد بررسی قرار گرفت. آزمایش سمیت تماسی روی حشرات 1 تا 7 رو...
OBJECTIVE The Crimean-Congo haemorrhagic fever virus (CCHFV), which is transmitted by the ticks of Hyalomma spp. in general and H. marginatumin particular, can cause severe disease in humans, with mortality rates of 3-30%. Other than from the bites of infected ticks, CCHFV can also be transmitted through contact with patients with the acute phase of infection or contact with blood or tissues fr...
Habitat loss and climate change pose a double jeopardy for many threatened taxa, making the identification of optimal habitat for the future a conservation priority. Using a case study of the endangered Bornean orang-utan, we identify environmental refuges by integrating bioclimatic models with projected deforestation and oil-palm agriculture suitability from the 1950s to 2080s. We coupled a ma...
Four orangutans (1 juvenile, 2 subadults, and 1 adult) and ten 6-8-year-old children were tested in 4 liquid conservation tasks of increasing levels of difficulty. Task difficulty depended on the type of transformation (continuous vs. discontinuous quantities) and the relative contrast between the shapes of the containers. Results indicate that orangutans did not display conservation in the str...
the photocatalytic degradation of two anionic azo dyes acid red88 (ar 88) and acid orange 7 (ao7) was investigated in aqueous solution using a tio2-containing hydrogel and uv light. the ph-sensitive hydrogel poly (styrene-alt-maleic anhydride) (psma), was synthesized and crosslinked in the presence of melamine and tio2 nanoparticles which results in entrapment of tio 2 into the melamine-grafted...
