Growth, yield attributes, yield and economics of winter popcorn (Zea mays everta Sturt.) as influenced by planting time fertility level and plant population under late sown condition

The field experiment was laid out in split plot design with three replications, assigning in 27 treatment combinations i.e. three sowing dates of Pop corn (Zea mays everta Sturt.)cv. V.L. Amber (15 Dec, 30 Dec and 15 Jan) arranged in main plots and three level of plant population (60000, 80000 and 100,000 plants ha-1) in sub plot. Three level of fertility (100:50:50, 150:65:65 and 200:85:85 kg of N: P2O5: K2O ha-1) apportioned in sub-sub plots at the Research farm, Institute of Agricultural Sciences, BHU, Varanasi (U.P.) during late winter (rabi) seasons of 2009-10 and 2010-11 to study the influenced of planting time, fertility level and plant population on yield attributes, grain yield and economics of winter popcorn (Zea mays everta Sturt.) under late sown condition. The popcorn sown on 15th December recorded highest plant height, leaf-area index, dry matter, popcorn growth rate, yield attributes and yield of pop corn were significantly (P<0.05) affected and recorded highest benefit cost ratio (3.78). While, the maintenance of 80,000 popcorn plants/ha proved optimum for pop corn as it significantly (P<0.05) recorded highest number of kernel cob-1,grain yield (32.61 q/ha) and shelling percentage against density of 60,000 plants, while remained at par in straw yield over 100,000 plants. Application of 200: 85: 85 kg N: P2O5: K2O/ha significantly (P<0.05) increased growth, yield attributes and grain yield over 100: 50: 50 and 150: 65: 65 kg N: P2O5: K2O/ha and fetched the highest B: C ratio (3.14)

Short-period modulations in aerosol optical depths over the central Himalayas: role of mesoscale processes

Multiyear measurements of spectral aerosol optical depths (AODs) were made at Manora Peak in the central Himalaya Range (29°22N, 79°27E, ~1950 m above mean sea level), using a 10-channel multiwavelength solar radiometer for 605 days during January 2002-December 2004. The AODs at 0.5μm were very low (≤0.1) in winter and increased steeply to reach high values (~0.5) in summer. It was observed that monthly mean AODs vary significantly (by more than a factor of 6) from January to June. Strong short-period fluctuations (within a daytime) were observed in the AODs. Further investigations of this aspect have revealed that boundary layer dynamics plays a key role in transporting aerosols from the polluted valley region to higher altitudes, causing large contrast in AODs between forenoon and afternoon. The seasonal variations in AODs, while examined in conjunction with synoptic-scale wind fields, have revealed that the transport of dust aerosols from arid regions to the valley regions adjacent to the observational site and their subsequent transport upward by boundary layer dynamics are responsible for the summer increases

Toxicity Study of Heavy Metals Pollutants in Waste Water Effluent Samples Collected From Taloja Industrial Estate of Mumbai, India,

Abstract The present research work deals with the assessment of pollution due to toxic heavy metals in the industrial waste water effluents collected from Taloja industrial belt of Mumbai. The study reveals that dyes, paints, pharmaceutical and textile industries are some of the major industries contributing to the heavy metal pollutants in the surrounding aquatic environment. It was observed that paint manufacturing industries are the major contributors of toxic Cr, Zn and Pb amounting to 35.2, 33.1, and 31.4 mg/L respectively. It was also observed that major contribution of Cu (33.3 mg/L) was from dyes manufacturing units, while maximum Fe concentration of 12.8 mg/L was found in effluent samples released from textile industries. The concentration of Cd and Ni was found maximum in effluent samples collected from pharmaceutical industries amounting to 35.8 and 33.6 mg/L respectively. The overall results point out high concentration of toxic heavy metals in the effluent samples collected from different industries. These industrial effluents will pollute the near by water bodies affecting the growth of vegetation and aquatic life. These toxic heavy metals when released in aquatic environment will enter the food chain through bio-magnification causing various health problems in humans. The results of the present investigation point out the need to implement common objectives, compatible policies and programmes for improvement in the industrial waste water treatment methods

Lattice sites of ion-implanted Li in diamond

Published in: Appl. Phys. Lett. 66 (1995) 2733-2735 citations recorded in [Science Citation Index] Abstract: Radioactive Li ions were implanted into natural IIa diamonds at temperatures between 100 K and 900 K. Emission channelling patterns of a-particles emitted in the nuclear decay of 8Li (t1/2 = 838 ms) were measured and, from a comparison with calculated emission channelling and blocking effects from Monte Carlo simulations, the lattice sites taken up by the Li ions were quantitatively determined. A fraction of 40(5)% of the implanted Li ions were found to be located on tetrahedral interstitial lattice sites, and 17(5)% on substitutional sites. The fractions of implanted Li on the two lattice sites showed no change with temperature, indicating that Li diffusion does not take place within the time window of our measurements.

Mitigation of Non Linear Induced Harmonics In Grid Using Droop Controlled PV Based DG Shunt APF

This paper exhibitions the network tied Solar Photovoltaic generator system providing to nonlinear loads based Shunt Active Power Filter for reactive power remuneration and symphonious moderation by hang control technique. Solar PV system is a promising wellspring of vitality with incredible enthusiasm for spotless and sustainable power sources. The rising number of power hardware based gear is bringing about quality issues of electric power supply. Both high power mechanical loads and residential loads cause numerous unsettling influences in the utility side, for example, music, awkwardness, lists, swells, glimmers and recurrence variety. Power quality issues may emerge in the system or might be made by the buyer itself. In this paper, the proposed controller using power references demonstrates some huge changes in principle and a basic control topology. The PV module is associated with the DC side of Shunt Active Filter through the DC-DC converter. Converter switch is controlled by Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) calculation and it dispenses with the disadvantage in the regular PV system. A copying utilizing MATLAB Simulink is displayed to approve the benefit of the proposed system

α\alpha-emission channeling investigations of the lattice location of Li in Ge

The $\alpha$-emission channeling and blocking technique is a direct method for lattice site determination of radioactive atoms in single crystals. Position-sensitive detection of emitted $\alpha$ -particles provides an efficient means of carrying out such experiments at very low doses (10$^{10}$-10$^{11}$ implanted probe atoms per spectrum). Comparison of the experimental data to Monte Carlo simulations of complete two-dimensional channeling patterns (e.g. ±2°C around , and axes, which also includes all relevant planar directions) allows for straight-forward identification and rather accurate quantitative determination of occupied lattice sites, while at the same time the energy spectrum of emitted a particles gives information on the probe atom depth distribution. We illustrate this for the case of ion implanted $^8$Li (t_=0.8 s) in Ge, where we identify mainly tetrahedral Li at room temperature, and bond-centered Li at slightly elevated temperature

Entanglement and Nonunitary Evolution

We consider a collapsing relativistic spherical shell for a free quantum field. Once the center of the wavefunction of the shell passes a certain radius R, the degrees of freedom inside R are traced over. We show that an observer outside this region will determine that the evolution of the system is nonunitary. We argue that this phenomenon is generic to entangled systems, and discuss a possible relation to black hole physics.Comment: 14 pages, 1 figure; Added a clarification regarding the relation with black hole physic
