Key precursor 3 has been prepared under mild conditions in presence of tetrabutylammonium bromide (TBAB) as a phase transfer catalyst. All the synthesized compounds (5a-h) were screened for their antibacterial activity and inhibition of α-amylase of insect pest, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionadeae). Biological activity evaluation study revealed that among all the compounds screened, compound 5g found to have promising inhibition of α-amylase of insect pest, Tribolium castaneum. All the synthesized compounds revealed insignificant antimicrobial activity against pathogenic bacteria even at 500 μg/mL.

Understanding the psychological mechanism of consumers‘ purchasing behaviour is important for both buyers and sellers in social commerce platform. This study will examine the nature and role of psychological contract (PC), which is an utmost important variable, in social commerce context. Psychological contract comprises a consumer‘s beliefs about the reciprocal obligations that exist between him/her and sellers or other social members. Specifically, we propose that consumers may make purchase decisions by two processes, in which two types of PC--transactional contract and relational contract are the key mediators. In addition, we further discuss the antecedents (platform website ethics, and reliability of social elements) and consequences (trust and satisfaction in platform) of PC, and their collective impact on purchase intentions. We plan to empirically test our model by collecting survey data from the users...

The hazardous solid agro-industrial wastes which include: wheat straw ash, rice husk ash, corn cob ash and sugarcane bagasse ash (SCBA), having pozzolanic properties, have a versatile use in concrete. The solid pozzolana enhances the various concrete properties by the reaction of silicates with calcium hydroxide in the presence of water, which in result generate a saturated zone of calcium silicate hydrate (CSH) gel. This C-S-H gel reduces the amount of calcium hydroxide C(OH)2 during the hydration process of cement. Very limited research works have been done on concrete by partially replacing cement with SCBA. This research work was focused on evaluating the properties of concrete by partially replacing cement with SCBA at 0, 5, 10, and 15 percentages. Compressive strength, Strength activity index, and water absorption of all mixes were examined. And it...

Here, we investigated whether tACS can reach and modulate the excitability of the visual cortex in a frequency-dependent manner. METHODS: We measured the cortical excitability of the visual cortex using single pulse transcranial magnetic stimulation (TMS) while delivering tACS to the occipital region at different frequencies (5, ...
