A simple, sensitive and highly selective direct colorimetric method for the determination of Iron in biological samples is developed.Iron reacts with o-phenanthroline and reduced from Fe3+ to Fe2+ by the use of an excess of hydroxylamine HCl to form a orange red complex ion.It was measured at an absorption maximum of 510 nm.Beer's law was obeyed in the concentration range of 20-200 µg/mL.The method was applied successfully to a number of biological samples (female wistar rats' liver), plant samples (pearl millet seeds).The method is very simple and requires no solvent extraction or pre-concentration steps.
We report on a cost effective, portable urban air pollution monitoring device, Envirobat, based on commercially available gas sensors. In order to carry out air pollution monitoring over an extensively large area, the device integrates inexpensive solid state sensors, along with GSM Module which transmits measured data at multiple ground sites to a centralized server through GPRS. This device facilitates rapid dissemination of information on pollution levels at multiple ground sites simultaneously. The device has the capability to sense location, atmospheric pressure, temperature, humidity, CO 2 , CO, SO 2 , NO 2 , and O 3 . The device is validated through calibration and deployment for indoor and outdoor sensing applications.
Around the world, billions of people access the internet today. Intrusion detection technology is a new generation of security technology that monitor system to avoid malicious activities. The paper consists of the literature survey of Internal Intrusion Detection System (IIDS) and Intrusion Detection System (IDS) that uses various data mining and forensic techniques algorithms for the system to work in real time. Data mining methods are proposed for cyber analytics in support of intrusion detection.
The field experiment was conducted during summer season of 2015 and 2017 at Agronomy Research Farm of N. D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), to study the “Weed management studies in Japanese mint (Mentha arvensis L.)”. The experiment consisted of 14 treatment combination with propaquizafop - p - ethyl @ 40 g ha-1 as post-emergence (T1), propaquizafop - p - ethyl @ 60 g ha-1 as post-emergence (T2), propaquizafop - p - ethyl @ 80 g ha-1 as post-emergence (T3), propaquizafop - p - ethyl @ 100 g ha-1 as post-emergence (T4), clodinafop propargyl @ 40 g ha-1 as post-emergence (T5), clodinafop propargyl @ 60 g ha-1 as post-emergence (T6), clodinafop propargyl @ 80 g ha-1 as post-emergence (T7), Pendimethalin @ 1000 g ha-1 as pre-emergence (T8), oxyfluorfen @ 200 g ha-1 as pre-emergence (T9), imazethapyr + imazamox @ 80 g ha-1 as post-emergence (T10), imazethapyr + pendimethal in (RM) @1000 g ha-1 as pre-emergence (T11), imazethapyr @ 60 g ha-1 as post-emergence (T12), Weed free (Three hand weeding at 20, 45 and 65 DAP) (T13) and weedy check (T14). The treatments were replicated three times in a randomized block design. All weed management practices proved effectiveness for controlling the weeds in Japanese mint and recorded significantly lesser weed density, dry weight, weed index, nitrogen removal by weeds and higher weed control efficiency over weedy check. Pre emergence application of imazethapyr + pendimethalin at 1000 g ha-1 was found most effective for control of all major weeds and recorded minimum weed density (29.68 and 27.11), dry matter (29.07 and 27.08g.), weed index (8.82 and 8.68%), nitrogen removal (7.19 and 5.90 kg ha-1) and maximum WCE 92.76 and 93.88% during 2015 and 2017, respectively, which was significantly superior to rest of the treatments while at par with application of imazethapyr + and @ 80 g ha-1 as post emergence, pendimethalin @ 1000 g ha-1 as pre emergence and imazethapyr @ 60 g ha-1 as post-emergence for effective control of weeds.
The oriental fruit fly, Bactrocera dorsalis (Hendel) is a major pest of mango crop in India and the present studies conducted to estimate the number of generations in relation to changing temperature on mango fruits across eight different geographically isolated major mango growing locations of India. The prediction of insect pest generations and generation time was done for baseline (1961 to 1990),present (1969 to 2005), near future (2021 to 2050) and distant future (2071 to 2098) periods using A1B emission scenario data from the regional circulation model (RCM), Providing Regional Climates for Impacts Studies (PRECIS) model. The degree days models using minimum and maximum temperature were used to obtain cumulative degree days (DD) for each generation of B. dorsalis using a temperature threshold of 13°C. It was estimated that faster accumulation of degree days would make possible for occurrence of one or two additional generations with shortened mean life cycle (5 to 7 days less) in near and distant future climate change periods compared to baseline and present periods at majority of locations. Increased number of generations and reduction of generation time at majority of mango growing locations of India suggest that the incidence of B. dorsalis may likely to increase due to projectedincrease in temperatures during future climate change scenarios.
Mastitis is considered as one of the important production disease in dairy cows which incurs huge economic losses to dairy industry, despite considerable efforts has been dedicated to solve it for the last two decades. In the present study, the impact of dry cow therapy (DCT) on incidence of clinical mastitis, milk yield and composition in crossbred cows was studied. About 20 healthy crossbred cows were selected at dry-off and randomly allotted either to control or treatment group. Daily milk yield of cows was recorded up to 45 days post-partum and fortnightly separate quarter wise milk samples were collected for estimation of milk composition. While no quarter in the treatment group showed clinical mastitis, 33.33% of quarters in control group showed clinical mastitis within 45 days post-partum. Milk production increased by 9.71, 8.40 and 18.18% during first, second and third fortnight with overall value 11.84% during the entire 45 days post-calving period in DCT treated cows compared to control group. Also, the overall fat-corrected milk, solid-corrected milk and energy-corrected milk production following 45 days post-partum increased significantly (P<0.05) by 22.71, 23.70 and 22.80%, respectively in treated group than control group. However, overall mean milk components such as fat, protein, lactose, SNF and TS remained similar between treatment and control groups. Taken together, the above results indicated that DCT increased milk yield by reducing incidence of clinical mastitis during early lactation.
This study was conducted to evaluate the concentration of micro minerals (Zn, Fe, Mn, Co and Cu) of feeds and their distribution in fiber fractions (Neutral Detergent Fiber/NDF and Acid Detergent Fiber/ADF). Three species of common feeds namely ground nut cake (Arachis hypogaea), mustard cake (Brassica juncea), soybean meal (Glycine max), were collected. Micro minerals concentration in the feed samples and fiber fractions were analyzed using Inductively Coupled Argon Plasma Optical Emission Spectrophotometer (ICP-OES) Icap 6000 Series. The results showed that micro minerals concentration of feed and their distribution in fiber fraction varied among species. The concentration of all the minerals in feed was above the critical level. Distribution of micro minerals in NDF and ADF were also estimated. Iron (Fe), copper (Cu), zinc(Zn), in feeds were the highest elements associated in NDF and ADF, while the lowest was found in cobalt (Co) and manganese(Mn).

Abstract Acoustic parameters such as acoustic impedance, intermolecular free length, adiabatic compressibility, relative association, and Gibb’s free energy of polyethylene glycols of molecular weight 200 and 600 in methanol butylparaben solution were investigated using ultrasonic velocity and density measurements at temperatures T=293.15 and 298.15k and experimental pressure p=0.1MPa. The acoustic parameters adiabatic compressibility and intermolecular free length obey the same pattern as these measured parameters; however, the parameter acoustic impedance follows the opposite trend. In the current scheme under investigation, there are strong interactions between the solute and solvent molecules.
