abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
abstract a field experiment was conducted at plant pest and disease research institute in karaj,iran in 2005-2006 to determine the effect of low herbicide dose of clodinafop-propargyl on percentage of wild oat control, yield and economic return of wheat. the experiment included 2 wheat varieties (rooshan and niknejad (less and more competitiveness cultivar, respectively, 4 wild oat densities (0...
In order to study chemical weed control in cycloxydim tolerant maize (CTM) using cycloxydim herbicide, an experiment was carried out in a randomized complete block design with three replications during 2014. Treatments included conventional corn herbicides application (Nicosulforun, Foramsulfuron, Eradican and 2, 4-D + MCPA) in their recommended doses and combined treatment of cycloxydim + (dic...
The present study was carried out at Regional Research Station, CCS Haryana Agricultural University, Karnal, during winter (rabi) seasons of 2019–20 and 2020–21. In this experiment, ZT-wheat (Triticum aestivum L.) sown with happy seeder under surface residue load 6 t/ha (chopped). Fourteen weed control treatments including pre-emergence herbicide (pendimethalin 1500 g/ha), sequential applicatio...
Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...
BACKGROUND & OBJECTIVES Insect growth regulators (IGRs) offer alternatives to conventional chemical larvicides that pose problem of resistance and environmental safety. However, only a limited number of IGRs have been approved for use in mosquito control. In the present study, two new formulations of the IGR diflubenzuron, 2 per cent granular (GR) and 2 per cent tablet (DT) were tested for its ...
Field pea (Pisum sativum L) crop was conducted at the Agricultural Research Farm of B. H. U. Varanasi, during rabi season 2010-11. The experiment in randomized block design (RBD) with 10 weed control treatments viz., pendimethalin 1.0 kg ha-1 (PE), (PE) + imazethapyr 75 g (PoE), quizalofop- ethyl 60 50 chlorimuron- 4 (PPI), 1kg (PoE) and free (HW 30 DAS) were compared weedy check two irrigation...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
