A convenient protocol has been developed to fabricate well-defined nanorods of a photochromic molecule N-(3,5-di-tert-butylsalicylidene)-4-aminopyridine (DBSAP) by a laser ablation method. Reversible and fatigue-resistant optical switching and SHG activity were demonstrated. Interestingly, it was observed that DBSAP nanorods exhibit intermediate photochromic properties compared to solution and ...

A recent study using Heckman-type selection models to adjust for non-response in the Zambia 2007 Demographic and Health Survey (DHS) found a large correction in HIV prevalence for males. We aim to validate this finding, replicate the adjustment approach in other DHSs, apply the adjustment approach in an external empirical context, and assess the robustness of the technique to different adjustme...

A greenhouse experiment was conducted in 2013 in Research Lab of Karaj Islamic Azad University to determine the yield and activity of chemical markers as the response to different concentrations of Cadmium (Cd) (0, 5, 10 and 20 mg of Cd/kg of soil) in wheat cultivars (Karaj 1 and Karaj 2). Treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. The respon...

Reaction of the hydrogenheptaphosphide dianion, [HP(7)](2-), with one equivalent of bis(2,6-diisopropylphenyl)carbodiimide yielded the exo-functionalized cluster [P(7)C(NDipp)(NHDipp)](2-) (Dipp = 2,6-diisopropylphenyl). This species was characterized by single crystal X-ray diffraction, multielement NMR spectroscopy and electrospray mass-spectrometry. DFT calculations on the dianion were also ...

خشکسالی یکی از مخاطرات اصلی مرتبط با هواشناسی است. این مخاطره طبیعی بر تمام جوانب زندگی بشر مؤثر است. این پدیده از عوامل متعددی همچون بارندگی، دما، تبخیر-تعرق، مقدار آب موجود درخاک و غیره تأثیر می-پذیرد. خشکسالی در هر وضعیت اقلیمی ممکن است رخ دهد. پیش¬بینی خشکسالی نقش مهمی در کاهش خسارات ناشی از آن در بخش¬های مختلف بر عهده دارد. برای این که بتوان خشکسالی را از نظر کمی تعریف کرد، روش¬های متعددی ...
