Adsorption of Methylene Blue Dye from Industrial Effluents Using Coal Fly Ash

Industrial Wastewater contains several type of dye, causing serious environmental hazard. The discharge of highly colored effluents into natural water bodies not only is aesthetically displeasing, but also impedes light penetration, thus upsetting biological processes within stream and thus required treatment before discharge into a water body. In the present study, fly ash generated from coal based thermal powers station has been converted into a low-cost adsorbent for the removal of Methylene Blue from effluents of textile industry. Batch studies have been carried out to study the effect of pH, adsorbent doses, adsorbate concentration, temperature and contact time. The results of batch studies reveal that the adsorption of Methylene Blue is strongly pH dependent and maximum Methylene Blue removal is observed at equilibrium pH of 7.0. Optimum adsorbent dose and contact time are found to be 10 g/l and 360 minutes respectively. Kinetic studies have been performed to have an idea of the mechanistic aspects and to obtain the thermodynamic parameters of the process. The results also show that adsorption decreases with increase in temperature thereby showing the process exothermic in nature. Adsorption data have also been correlated with both Langmuir and Freundlich isotherm models

Study of Vagendriya with its Related Structures - A Review

According to Ayurveda classic texts Indriyas are the apparatus to attain knowledge for Atma. Acharya Charaka described Indriya as basic instrument in differentiating the living and non-living matters. Whereas in contemporary science Indriyas are dealt only with structure i.e. sense organ where the actual transduction process takes place. Indriyas are composed of five elements still specific Mahabhuta dominates precise Indriya. This is the reason behind reception of specific sensation by its respective Indriya. Many sensory and motor functions are performed by Indriyas. Indriyas of human body plays a very vital role in carrying out day to day activites of human body. Modern science also accepts the same concept in the form of sensation and perception that allows the human to detect and understand the various stimuli and collect information from internal or external environment of an organism and send them to CNS. All Indriyas work will be meaningless if Vayu will not work hand to hand with these Indriyas. Vagendriya a motor organ which act as a passive partner on receiving command from its higher centre located in Shira, which is ultimately a site for location of control center of all motor as well as sense organs and thus it is said to be ‘Uttamaang.’ Ayurvedic approach towards speech production is reflected as Vak Pravrutti. Speech is multiphase unique phenomenon and is believed to be outcome of combined effort of Acoustic signals, Articulatory signals and Muscle coordination along with Nervous assistance viz. Wernicke’s area and Broca’s area

Not AvailableThe investigaqtion was carried out at CSWCRTI, Research Farm, Selakui, Dehra Dun to see the productivity of groundstorey crops with different tree species. The cropping sequence (jowar-toria) was tested with three plantations i.e. Eucalyptus hybrid, Bombax ceiba and mixe plantations (natural) of Cassia fistula, Bombax ceiba, Acacia catechu, Lannea coromandalica and Dalbergia sissoo. It was observed that about 14.89, 12.79 and 12.14 t/ha green fodder yieldof jowar can be obtained with Bombax ceiba, Eucalyptus hybrid and mixed plantation respectively. Thr ttend was same with toria and seed yield recorded were 3.68, 2.78 and 2.38 q ha under Bombax ceiba, Eucalyptus hybrid and mixed plantations, respectively. The yield of both the crops increases with increasing distance from the tree trunk, however the direction did not influence the yield of groundstorey cros.Not Availabl

Assessing Customers' Attitude towards Online Apparel Shopping: A Three-Way Interaction Model

This paper aims to explore the attitude-intention-purchase behavior mechanism for the online purchase of apparel. Using the theory of planned behavior (TPB) as an underpinning theory, the moderating effects of electronic word of mouth (EWOM), perceived risk, and perceived behavioral control in the relationships have been examined. Data were collected from 432 online apparel consumers using a survey questionnaire. First, the instrument's psychometric properties were checked, and then data was analyzed using Hayes's PROCESS macros. The results indicate that online purchase intention mediates the relationship between consumers' attitudes toward online shopping and actual purchase behavior. In addition, the results found strong support for the three-way interactions between attitude, perceived risk, and EWOM on purchase intention, and (ii) attitude, EWOM, and perceived behavioral control on actual purchase behavior mediated through purchase intention. The three-way interactions involving the double-moderation of EWOM make significant contributions to the growing literature on online buying. \textcopyright 2023 Elsevier Inc

An 8 MeV Electron Beam Modified In:ZnO Thin Films for CO Gas Sensing towards Low Concentration

In the present investigation, electron beam-influenced modifications on the CO gas sensing properties of indium doped ZnO (IZO) thin films were reported. Dose rates of 5, 10, and 15 kGy were irradiated to the IZO nano films while maintaining the In doping concentration to be 15 wt%. The wurtzite structure of IZO films is observed from XRD studies post electron beam irradiation, confirming structural stability, even in the intense radiation environment. The surface morphological studies by SEM confirms the granular structure with distinct and sharp grain boundaries for 5 kGy and 10 kGy irradiated films whereas the IZO film irradiated at 15 kGy shows the deterioration of defined grains. The presence of defects viz oxygen vacancies, interstitials are recorded from room temperature photoluminescence (RTPL) studies. The CO gas sensing estimations were executed at an optimized operating temperature of 300 °C for 1 ppm, 2 ppm, 3 ppm, 4 ppm, and 5 ppm. The 10 kGy treated IZO film displayed an enhanced sensor response of 2.61 towards low concentrations of 1 ppm and 4.35 towards 5 ppm. The enhancement in sensor response after irradiation is assigned to the growth in oxygen vacancies and well-defined grain boundaries since the former and latter act as vital adsorption locations for the CO gas

Antibiotics potentiating potential of catharanthine against superbug <i>Pseudomonas aeruginosa</i>

<p>Multidrug resistance (MDR) put an alarming situation like preantibiotic era which compels us to invigorate the basic science of anti-infective chemotherapy. Hence, the drug resistant genes/proteins were explored as promising drug targets. Keeping this thing in mind, proteome of <i>Pseudomonas aeruginosa</i> PA01 was explored, which resulted in the identification of tripartite protein complexes (MexA, MexB, and OprM) as promising drug target for the screening of natural and synthetic inhibitors. The purpose of present investigation was to explore the drug resistance reversal potential mechanism of catharanthine isolated from the leaves of <i>Catharanthus roseous</i>. Hence, the test compound catharanthine was <i>in silico</i> screened using docking studies against the above receptors, which showed significant binding affinity with these receptors. In order to validate the <i>in silico</i> findings, <i>in vitro</i> evaluation of the test compound was also carried out. In combination, catharanthine reduced the minimum inhibitory concentration MIC of tetracycline (TET) and streptomycin up to 16 and 8 folds, respectively. Further, in time kill assay, catharanthine in combination with TET reduced the cell viability in concentration dependent manner and was also able to reduce the mutation prevention concentration of TET. It was also deduced that drug resistance reversal potential of catharanthine was due to inhibition of the efflux pumps.</p
