Abstract:A precise, robust and accurate method was developed for estimation of Fluocinolone Acetonide, Miconazole Nitrate, Chlorocresol, Methyl paraben and Prolyl Paraben, from cream dosage form. The gradient was optimized on BDS Hypersil C18, 250 x 4.6 nm 5μm column, operated at 45°C and mobile phase A and B were selected as monobasic phosphate buffer pH 7.2 and Acetonitrile, pumped at 1.5 ml/min. flow rate. All the solutions were injected at 20 μl injection volume and monitored at 238 nm. The Methylparaben, Propylparaben, Chlorocresol, Fluocinolone acetonide and Miconazole were eluted at about 4, 9, 9.8, 11and 25 minutes respectively. The recoveries were found between 98.0 to 102.0 % for each analytes. The method was found linear from 50 to 150 % of sample concentration and linear regression curves, (r2) were more than 0.999 for all the analytes. The developed method was remains unchanged after deliberate variation in method parameters hence proved the method robustness. The developed method is time saving, cost effective hence can be used in pharmaceutical industries for simultaneous estimation of these compounds from cream and other dosage forms

Abstract:novel bio – adsorbent Lagenaria siceraria, chemically activated was prepared for the removal of chromium ions from aqueous solutions. Structure, morphology and pore size distributions were studied using SEM, EDAX and BET. The adsorption kinetics (Intra – particle diffusion, pseudo 1st order and 2nd order) and isotherms (Langmuir and Freundlich models) were used to analyse the adsorption capacities of chromium ions on the adsorbent surfaces at optimum pH, dose and contact time of 3, 4 g/L and 120 min respectively. The studied experimental data confirms that pseudo 2nd order kinetics fits best with a correlation coefficient (R2) of 0.99 but agrees well with both the Langmuir and Freundlich isotherms with correlation coefficients (R2) of 0.96 and 0.94 respectively. The maximum adsorption capacity attained was 6.325 mg/g with a maximum percentage removal of 86%.

Abstract:Eichhornia crassipes, Water Hyacinths is among the world’s most noxious invasive weeds. Climatic and water conditions are the main determinant factors for the growth and expansion of water hyacinth. The weed has substantial negative impacts on the Powai lake (Mumbai India) hydrology, socioeconomics, and aquatic ecosystem causing it to shrink. The lessons for management of Powai Lake water hyacinth are employing preventive and integrated management approaches. Reducing pollutant loads and nutrient enrichment through integrated watershed management is suggested to reduce the Powai Lake eutrophication. The hyacinth has come to cover over half the 688-hectare, and along with the highly polluted silt settled on the lakebed is fast killing organisms. Awareness about the water pollution caused by the immersion of Ganesh idols made out of Plaster of Paris, in natural water bodies such as lakes, rivers and the sea is growing and both municipalities and communities are changing their mindset towards biodegradable idols. There are extensive records and examples of clay, bamboo and straw being used in ancient Indian idols made out of naturally occurring clay (shaadu in Marathi) which dissolve within hours of immersion in water, whereas pop idols may take anywhere between several months to fully dissolve. In addition, when chemical paints are used to decorate the idols, these paints contain heavy metals such as mercury and lead, which seep into the water as the idol dissolves. AIM This paper will review the- Issues, sustainable development of Lake Agro waste focusing on Environment, Economy. -Use of recycling Water Hyacinths into Eco friendly Ganesha idols, Bio bricks and sustainable products/ fabric giving this agro waste economic value instead of being burnt in landfills emitting dangerous gases, after being transported usurping fuel and manpower. - Collection and recycling of the water hyacinths to prevent shrinking of the Powai Lake. - Saving the rich Biodiversity of Powai Lake and its fauna and flora. - Pollution/ climate change mitigation by stakeholders - Role of Community in the circular economy of water hyacinths (agro/ aquatic waste) Conclusion Every few years the government spends crores of rupees on cleaning the water body of water hyacinths only to leave it wasted at overloaded landfills. The Water Hyacinths at the Powai lake can be treated as aquatic Waste and be of economic value via eco-friendly bi-products, providing jobs in a post COVID-19 scenario and involving climate change mitigation outlining sustainable development of our water bodies.

Abstract:Artificial Intelligence (AI) can play an important role in boosting agriculture thus helping agricultural-based economies grow. Agriculture can take advantage of emerging technologies such as AI-based Automated Smart Systems to increase irrigation, crop monitoring, farming, automatic spraying and improve pesticide use and weed control. Many mobile applications can be created that use the power of AI to assist farmers by providing a variety of services ranging from better commercial opportunities in managing and growing field yields.

Abstract:Abstract---Food security has, tremendously, been imperiled globally by climate change and variability. Sundry efforts put by different organizations to address food insecurity has not, sufficiently, attenuated the problem. This is exacerbated by the rapidly growing population against the dwindling production resources. The problem is even worse in Arid and Semi-Arid Lands (ASALs) whose environmental conditions, for crop growth, are quite fragile. Dry beans (Phaseolus vulgaris L.) are a crucial food crop, commonly grown in these areas since they provide cheap source of proteins for poor households. However, beans production, in these fragile agro-ecologies, is impeded by sporadic rainfall, erratic rainfall, meagre soil nutrients, low moisture levels, nutrients fixation among other factors. A field-based study was undertaken at South Eastern Kenya University (SEKU), Kenya, and Kenya Agricultural and Livestock Research Organization (KALRO), Kenya, to determine the efficacy of foliar fertilizer nutrition on commonly grown bean varieties in semi-arid area of South Eastern Kenya. In the first season, the study was undertaken in Teaching and Research Farm of SEKU, while the second season was done in KALRO substation at Ithookwe. In both seasons, treatments were arranged in a Randomized Complete Block Design (CRBD) and were replicated three times. The efficacy of three concentrations of foliar nutrients, (0/L or control), (2.5mls/L) and (5mls/L), on grain yield of three bean varieties was evaluated. Data was collected on Leaf Area Index (LAI), number of pods, and grain yield. The results in both seasons exhibited that, Wairimu and Wairimu dwarf had the highest LAI of 0.08 and 0.09 respectively and were not significantly different from each other in both seasons; it was followed by Piriton (0.06) and KAT B9 (0.05) but were, also, not statistically different from each other. In terms of number of pods per plant, in season 1 and 2 respectively, Wairimu had the highest number (21.77, 26.83) followed by Wairimu dwarf (19.44, 27.66), Piriton 25.33) and KAT B9 13.32, 16.00) in that order. The grain yield, in both seasons (kg/ha), showed that Wairimu had the highest yield of (440.08, 439.60), followed by Wairimu dwarf (385.69, 388.71), Piriton (386.09, 382.13), and KAT B9 (381.45, 379.58) in that order In view of the above findings, the study recommends use of foliar nutrients/ fertilizers at the rate of 5.0 mls/L, as oppose to the conventional use of 2.5mls/L, in increasing the yields of the four aforementioned varieties, commonly grown in ASALs.
