STUDIES ON NANOPARTICLE INDUCED NUTRIENT USE EFICIENCY OF FERTILIZER AND CROP PRODUCTIVITY

A field experiment was conducted at M/s.Rashtriya Chemicals and Fertilizers, Ltd., Mumbai, India, (RCF) experimental farm to evaluate the effect of ZnO Nanoparticles (ZnO NP) in combination with N: P: K (15: 15:15) complex fertilizer “Suphala” of RCF Ltd. on growth attributes of brinjal (Solanum melongena L) as well as nutrient use efficiency. The experiment was carried out in randomised block design with three replications. The first treatment (T-1), comprised of recommended dose of fertilizer (RDF), N: P: K (50:50:50), applied at the time of transplantation. The second treatment (T-2) was conducted with RDF in combination @ 2kg ZnSO4 (bulk)/ha. The third treatment (T-3) was added, N: P: K (12.5; 12.5; 12.5) in combination to ZnO NP @ 4500mg/ha. The forth treatment (T-C) was without any fertilizer. All treatments were given appropriate quantity of nitrogen per hectare as urea at the 30th day of transplantation. The combination N: P: K (12.5; 12.5; 12.5) and ZnO NP @ 4500mg/ha yielded 91% and 45.3% higher brinjal yield and biomass respectively than the treatment with only RDF. It was also observed that 38% and 21% higher yield and biomass respectively were recorded in the treatment where combination of RDF with ZnSO4 (bulk) over RDF was used alone. The results of field trials reveal that, there was synergistic effect of ZnO NP @ 4500mg per hectare with N: P: K complex fertilizer on growth attributes of brinjal as well as nutrient use efficiency

Survey on Biometric Image Sharing Using Cryptography and Diverse Image Media

Visual Secret Sharing Scheme is used to transmitting or delivering the secret images over the network. The VSS scheme has a major drawback that is it suffers from high transmission risk because the shares are like noise. As the shares are like noise that causes the attackers attention. In this paper we are using a natural-image based visual secret sharing (NVSS) scheme to reduce the transmission risk problem that occurs in VSS scheme. The NVSS scheme uses the natural images such as paintings, photographs etc as digital shares. As we are using the natural shares instead of noise like shares which reduces the transmission risk to certain limit. This scheme also uses the different media to transmit the shares

Conversion of Natural Resources through Waste reduction at the Processing Step by Briquetting Technique

India is gifted by nature by way of large quantities of high grade nonferrous mineral resources like barite containing more than 90% barium sulphate. The processing of barite to win chemicals from it requires its carbotherrnic reduction at high temperatures being carried out in rotary furnaces. The powdered charge containing barium sulfide is prone to get damaged due to reverse reaction caused by infiltered oxygen at the end of reduction state. This hampers the yield of water soluble barium sulfide.The paper discusses about the means of achieving favourbale kinetics and high recovery of water soluble barium sulphide in the carbothermic reduction of barite at high temperatures. The reaction rate of reduction step was enhanced many folds by using briquetting technique. Even with barite containing large amnount of harmful impurites, the yield of barium was improved considerably on pilot plant scale, thus achieving better utilisation of natural resoures such as barite and coke

Study of potential drug interactions between prescribed drugs in geriatric patients attending outpatient department in a government tertiary care hospital in Maharashtra

Background: A drug interaction is defined as a modification of the effect of a drug when it is administered with other drugs. Geriatric population is exposed to multiple drugs and consequently suffers many drug interactions (DIs). The objective of this study was to assess the potential drug interactions (PDI) in the geriatric population attending out-patient department (OPD) in a tertiary care hospital.Methods: A cross sectional observational study was carried out from July to September 2015. Patients of either gender, age 60 years or more, attending OPD in tertiary care hospital and prescribed two or more drugs, were included in the study. Prescriptions of medical officers were screened for PDIs with Medscape drug interaction software available on the website www.medscape.com.Results: In the present study, out of 600 prescriptions, 48.50% were identified having at least one drug interaction. Total 584 PDIs were found in 111 drug pairs. 29.62% PDIs were pharmacodynamic, 42.80% pharmacokinetic type and 10.78% PDIs were found affecting serum potassium level. Majority of PDIs (61.81%) were found significant followed by minor (36.98%) and severe (1.19%). Ranitidine and cyanocobalamin was the most common pair showing PDI (105) followed by aspirin and enalapril (44). Aspirin was found to be the most common single drug amongst pairs to cause PDI in the present study.Conclusions: In the present study, PDIs were studied in geriatric population. Knowledge of the prevalence and predictors of clinically important PDIs will help physicians and pharmacists identify patients at higher risk of adverse drug interactions requiring more cautious pharmacotherapy
