In Vitro Anti Microbial Activity of Roylea elegans, Chrozophora tinctoria, and Daphniphyllum himalaense
Herbal combination plays a major role in enhancing the activity due to its synergetic effects. Many well-known plants possess their antibacterial activity individually, and a combination of these may lead to the better efficacy of results. Plants belonging to the family Euphorbiaceae and Laminaceae possess an excellent antibacterial effect against various bacteria. However, secondary metabolites like; terpenes, alkaloids, and phenolic compounds are well for their free radical scavenging activity, which may inhibit the growth of microorganisms. Thus, the combination of these herbal plants is evaluated for antibacterial activity using hydrogel forms solution
Ordered mesoporous carbon as adsorbent for the removal of a tripenylmethane dye from its aqueous solutions
Funding: This research was funded by Maulana Azad National Institute of Technology via a Senior Research Fellowship and by the Engineering and Physical Research Council (EPSRC) of the UK, grant numbers EP/T019298/1, EP/L017008/1 and EP/R023751/1). The APC was funded by the University of St Andrews.A nanostructured material, ordered mesoporous carbon (OMC), was synthesised in metal- and halide-free form and its use for the sequestration of crystal violet, a hazardous triphenylmethane dye, is reported for the first time. The OMC material is characterised using scanning transmission electron microscopy with energy-dispersive spectroscopy for chemical analysis, by Fourier-transform infrared spectroscopy, and by nitrogen gas physisorption. The ideal conditions for the uptake of crystal violet dye were determined in batch experiments covering the standard parameters: pH, concentration, contact time, and adsorbent dosage. Experimental data are validated by applying Langmuir, Freundlich, DubininâRadushkevich, and Temkin isotherms. The thermodynamic parameters, ÎH°, ÎG°, and ÎS°, are calculated and it has been found that the adsorption process is spontaneous and endothermic with increasing disorder. An in-depth analysis of the kinetics of the adsorption process, order of the reaction and corresponding values of the rate constants was performed. The adsorption of crystal violet over OMC has been found to follow pseudo-second-order kinetics through a film diffusion process at all temperatures studied. Continuous flow column operations were performed using fixed bed adsorption. Parameters including percentage saturation of the OMC bed are evaluated. The exhausted column was regenerated through a desorption process and column efficiency was determined.Peer reviewe
Post Event Investigation of Multi-stream Video Data Utilizing Hadoop Cluster
Rapid advancement in technology and in-expensive camera has raised the necessity of monitoring systems for surveillance applications. As a result data acquired from numerous cameras deployed for surveillance is tremendous. When an event is triggered then, manually investigating such a massive data is a complex task. Thus it is essential to explore an approach that, can store massive multi-stream video data as well as, process them to find useful information. To address the challenge of storing and processing multi-stream video data, we have used Hadoop, which has grown into a leading computing model for data intensive applications. In this paper we propose a novel technique for performing post event investigation on stored surveillance video data. Our algorithm stores video data in HDFS in such a way that it efficiently identifies the location of data from HDFS based on the time of occurrence of event and perform further processing. To prove efficiency of our proposed work, we have performed event detection in the video based on the time period provided by the user. In order to estimate the performance of our approach, we evaluated the storage and processing of video data by varying (i) pixel resolution of video frame (ii) size of video data (iii) number of reducers (workers) executing the task (iv) the number of nodes in the cluster. The proposed framework efficiently achieve speed up of 5.9 for large files of 1024X1024 pixel resolution video frames thus makes it appropriate for the feasible practical deployment in any applications
Vonoprazan: a promising advancement in proton pump inhibitor therapy
Vonoprazan, a potent potassium-competitive acid blocker (P-CAB), has emerged as a potential therapeutic option for acid-related disorders, particularly gastroesophageal reflux disease (GERD) and peptic ulcer disease (PUD). This comprehensive review aims to provide an overview of the efficacy, safety profile, and clinical implications of vonoprazan based on current literature. Efficacy studies have demonstrated vonoprazan's superiority over proton pump inhibitors (PPIs) in achieving effective acid suppression, rapid symptom relief, and promoting mucosal healing in patients with GERD and PUD. Moreover, its long-lasting acid suppression properties offer protection against Helicobacter pylori (H. pylori) infection, presenting it as a potential alternative to traditional triple H. pylori eradication regimens. Safety evaluations reveal a favourable tolerability profile with minimal adverse effects and a lower risk of drug interactions compared to PPIs. However, concerns regarding long-term safety, such as hypomagnesemia and the potential for rebound acid hypersecretion, necessitate further investigation. Additionally, the role of vonoprazan in special populations, such as the elderly and those with renal impairment, warrants exploration. Overall, vonoprazan represents a promising advancement in acid suppression therapy, offering efficacy, safety, and potential advantages over traditional agents

The dye adsorption over Hen Feather was comprehensively studied over ranges of contact time, pH, concentration, and adsorbent dosage, and the optimum values were evaluated. In order to understand the behaviour of the adsorption system, various isotherm models were evaluated at temperatures of 30, 40 and 50 °C. The data obtained from contact time studies were used to test pseudo-first and pseudo-second order kinetic models and it was found that the adsorption follows pseudo-second-order kinetics. Using the Langmuir constant, b, thermodynamic parameters including ÎG°, ÎH° and ÎS° were calculated and it was ascertained that the process is endothermic (positive ÎH°), involves an increase in disorder (positive ÎS°) and is spontaneous (negative ÎG°). The values of the separation factor (r) also confirmed a favourable adsorption process at all three temperatures studied. Overall, it is affirmed that the adsorbent, Hen Feather, acts as highly potent scavenger to remove the dye Aniline Blue from its aqueous solutions.Peer reviewe
SWEET FUTURE OF STEVIA: A MAGICAL SWEETENER
ĂÂ The plant Stevia rebaudiana is mainly found in tropical and subtropical regions from western North America to South America. This genus is having near about 240 species of shrubs and herbs in the sunflower family (Asteraceae). It exhibits various properties such as antibacterial, antifungal, anti-inflammatory, antimicrobial, antiviral, antiyeast, cardiotonic, diuretic, hypoglycemic, hypotensive tonic, and vasodilator effect. It is an important source of a number of antioxidants, for example, benzoic acid, caffeic acid, chlorogenic acid, ferulic acid, rozmaric acid, protocatechuic acid, salicylic acid, and their derivatives and flavonoids including campherol derivatives, catechin, and its derivatives, epicatechin, luteolin, and its derivatives, rutin, and its derivatives. Day by day, there is remarkable increase in demand of high potency sweeteners. The increasing number of diabetic patients and health conscious individuals would push forward the need for alternatives to sugar. The extract from leaves of Stevia is 200 times sweeter than sugar (glucose, fructose, sucrose, maltose, and lactose). Stevia is a potential alternative source for replacing artificial sweeteners such as saccharin, aspartame, and asulfam
Batch and bulk adsorptive removal of anionic dye using metal/halide-free ordered mesoporous carbon as adsorbent
The authors are grateful to the Ministry of Human Resource Development of the Government of India for financial support through the SPARC Project- SPARC/2018â2019/P307/SL. One of the authors (Asna Mariyam) is also grateful to MANIT, Bhopal for providing fellowship assistance. We thank the University of St Andrews for a PhD scholarship for FS. We acknowledge EPSRC Strategic Resources Grant (EP/R023751/1).The present report is an outcome of investigations to assess the adsorptive potential of a synthesized metal- and halide-free variant of ordered mesoporous carbon (OMC) towards an anionic azo dye, Methyl Orange. The results of preliminary studies, carried out in batch mode, helped in setting up the process variables to achieve optimum adsorption conditions. The experimental data were then fitted to Langmuir, Freundlich, Temkin, and Dubinin-Radushkevitch isotherm models. The equilibrium data fitted well to the Langmuir model at 303 K and the monolayer adsorption capacity was 0.33 mmol gâ1. The adsorption kinetics were explored by fitting the data to pseudo-first-order and pseudo-second-order kinetic models. The latter described the kinetics well, as indicated by higher regression coefficients. To elucidate the mechanism of mass transfer, various well-known mathematical models were employed. The adsorption of the dye was found to involve particle diffusion. Thermodynamic studies revealed that the adsorptive uptake of Methyl Orange by the OMC was spontaneous (ÎG0 = â23.71 kJ molâ1) and exergonic (ÎH0 = â123.15 kJ molâ1). Finally, the bulk removal of the anionic dye was investigated through column operations followed by column regeneration (desorption) studies. Column saturation of up to 96.55% could be realized. Values for dye recovery reached up to 93.26%. The column efficiency was then evaluated by carrying out three consecutive adsorption/desorption cycles. The results obtained indicated that the adsorbent has a good ability to eliminate Methyl Orange from wastewater, both in batch and column operations.PostprintPeer reviewe
Adsorptive removal of hazardous anionic dye ââCongo redâ from wastewater using waste materials and recovery by desorption
The present investigation assesses the applicability of waste materialsâbottom ash and deoiled soyaâfor the removal of the colorant Congo red from wastewaters. The adsorption characteristics and dye removal efficiency of adsorbents have been determined by investigating factors such as effect of pH, effect of concentration of the dye, amount of adsorbents, contact time, and temperature. Langmuir, Freundlich, Tempkin, and DubininâRadushkevich isotherm models have been used to evaluate the ongoing adsorption. With the help of adsorption isotherm data different thermodynamic parameters such as free energy; enthalpy, and entropy have been calculated. The estimated free energy has been obtained as 21.52 kJ mol1 for bottom ash and 16.88 kJ mol1 for deoiled soya. On the basis of pseudo-first-order and pseudo-second-order kinetic equations different kinetic parameters have been obtained. Column operations depicted good adsorptive tendencies for Congo red with 96.95% and 97.14% saturation of dye on bottom ash and deoiled soya, respectively. Regeneration of the saturated columns has been made by eluting NaOH solution and more than 90% dye has been recovered in both cases
Adsorption behaviour of Chrysoidine R dye on a metal/halide-free variant of ordered mesoporous carbon
Funding: Authors are grateful to the Ministry of Human Resource Development of the Government of India for financial support through the SPARC initiative (project: SPARC/2018-2019/P307/SL). One of the authors (Asna Mariyam) is thankful to MANIT, Bhopal for providing fellowship support.The paper reports the removal of Chrysoidine R, a toxic mono-azo dye from its aqueous solution by employing metal- and halide-free variant of ordered mesoporous carbon as adsorbent in batch experiments. The influence of various parameters such as hydronium ion concentration, adsorbent dosage, initial dye concentration, exposure time on dye uptake was studied. The process could be described by Langmuir, Freundlich and Dubinin-Radushkevitch isotherm models. Evaluation of thermodynamic variables proved that the adsorption was spontaneous, feasible and endothermic. The kinetics involved in the process was worked out using pseudo-first-order and pseudo-second-order kinetic models. The latter was found appropriate for the analysis of the experimental data. The mechanism governing the overall adsorption was elucidated with the aid of various mathematical models. The adsorption was found to proceed via film diffusion with chemisorption being the rate-determining step. The complete removal of dye with fast removal rate makes the material propitious in the field of water treatment.Peer reviewe
