Heterosis for post harvest and nutritional quality traits in tomato (Solanum lycopersicum L.)

A study was conducted in tomato using an 6 x 6 diallel crossing design excluding reciprocals to quantify the magnitude of heterosis and to identify the best heterotic combinations for post harvest and nutritional quality attributes viz. pericarp thickness (mm), fruit firmness (g/0.503 cm2), shelf life (days), total soluble solids (oBrix), lycopene content (mg/100g) and ascorbic acid (mg/100g) which are considered essential in present day hybrid varieties of tomato from consumer point of view. All the 22 entries (6 parents, 15 F1 hybrids and 1 standard check) were field evaluated using randomized complete block design with three replications during Kharif 2015-16. Highly significant heterosis (5% level of significance) of positive nature was found for pericarp thickness (22.90%, 32.20% and 5.62%), fruit firmness (17.32%, 56.72% and 9.21%), shelf life (17.54%, 24.87% and 9.57%), total soluble solids (24.44%, 51.44% and 34.20%), lycopene content (28.75%, 35.05% and 25.63%) and ascorbic acid (19.07%,30.00% and 17.85%) over the better, mid and standard check, respectively. Three promising crosses viz., Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were identified as high yielding F1 combinations having superiority to post harvest and nutritional quality traits in tomato and can be promoted for release and commercial cultivation

Assessment of Biomass Potential in Engine Emission Reduction

77-80The twin crisis of environmental degradation and fossil fuel depletion has confronted the world with the upcoming threat to seek the solution for some alternate fuel. The present condition of environment forces the search of some suitable alternate fuel. The present degradation of environment is also mainly influenced by the diesel vehicles. The emissions released by these diesel vehicles not only degrade the environment but also increase the number of health diseases. The present research on bio-fuels will lead to develop a sustainable solution to this problem and also create a harmonic relationship between the economy and ecosystem. The present research will provide the optimized blending ratio compression ratio and other operating parameters to be selected while approaching to sustainable output. The present study will depict the behavior of different bio-fuels poured in VCR engine at different compression ratio at different operating parameters. The outcomes of this research paper reveals the discussion on the potential assessment of different biofuels in the reduction of engine emissions

Experimental and numerical investigation on soft soil tunnels under impact loading condition

Background: Tunnels extend the use of underground space for special applications such as transportation, mine development and civil defense. These structures could become susceptible to severe dynamic loads such as traffic loads, pile driving, impact and blast loads. Methodology: In this context, the experiment and simulations were conducted on semi-cylindrical tunnels of dimensions 1.2 m length × ∅ 0.5 m center-to-center and 0.05 m lining thickness under impact loading. The drop height was kept at 3.0 m and the burial depths of the soil cushion were varied as 0, 0.05, 0.10 and 0.15 m to study the effect of the cushion layer under repeated impact load. The experimental results were obtained in terms of damage to the tunnel and displacements in the tunnel under repeated impacts. Results: It was observed that the impact resistance of tunnels increased significantly when the natural burial depth increased from 0.05 to 0.10 m. It was concluded that the tunnel with 0.15 m burial depth was able to resist up to nine impacts as compared to the tunnel without cushion which offered resistance against two impact only. The numerical investigations were performed for each tunnel under repeated impacts using ABAQUS/Explicit. The numerical results were found to be in good agreement with the experimental results in terms of strain in rebar and mid displacement. The parametric study was performed for the influence of mass and velocity of the impactor in terms of crack pattern, impact force, displacement and energy absorption capacity in the tunnel. On increasing the mass of the impactor from 150 (4.41 kJ) to 400 kg (11.77 kJ), the energy absorption capacity was found to increase from 7.8% to 48.7%; however, on increasing the height of drop from 5 (5.1 kJ) to 20 m (20.40 kJ), the energy absorption capacity of the tunnel was increased from 8.1 to 48.6%. Conclusions: It was concluded that under the low-velocity impact, energy absorption in the tunnel is more sensitive to the mass of the impactor as compared to drop height. It was observed that Yang Qixin's algorithm was the best predicting algorithm among others when comparing peak impact force with the numerical result.</p

A first principles investigation of cubic BaRuO3_3: A Hund's metal

A first-principles investigation of cubic-BaRuO$_3$, by combining density functional theory with dynamical mean-field theory and a hybridization expansion continuous time quantum Monte-Carlo solver, has been carried out. Non-magnetic calculations with appropriately chosen on-site Coulomb repulsion, $U$ and Hund's exchange, $J$, for single-particle dynamics and static susceptibility show that cubic-BaRuO$_3$ is in a spin-frozen state at temperatures above the ferromagnetic transition point. A strong red shift with increasing $J$ of the peak in the real frequency dynamical susceptibility indicates a dramatic suppression of the Fermi liquid coherence scale as compared to the bare parameters in cubic-BaRuO$_3$. The self-energy also shows clear deviation from Fermi liquid behaviour that manifests in the single-particle spectrum. Such a clean separation of energy scales in this system provides scope for an incoherent spin-frozen (SF) phase, that extends over a wide temperature range, to manifest in non-Fermi liquid behaviour and to be the precursor for the magnetically ordered ground state.Comment: 10 pages, 12 figures, 1 tabl

Estimation of NOx Emissions from Delhi Using Car MAX-DOAS Observations and Comparison with OMI Satellite Data

We present the first Multi-Axis-(MAX-) DOAS observations in India performed during April 2010 and January 2011 in Delhi and nearby regions. The MAX-DOAS instrument was mounted on a car roof, which allowed us to perform measurements along individual driving routes. From car MAX-DOAS observations along closed circles around Delhi, together with information on wind speed and direction, the NOx emissions from the greater Delhi area were determined: our estimate of 4.4 x 10(25) molecules s(-1) is found to be slightly lower than the corresponding emission estimates using the EDGAR emission inventory and substantially smaller compared to a recent study by Gurjar et al. (2004). We also determined NOx emissions from Delhi using OMI satellite observations on the same days. These emissions are slightly smaller than those from the car MAX-DOAS measurements. Finally the car MAX-DOAS observations were also used for the validation of simultaneous OMI satellite measurements of the tropospheric NO2 VCD and found a good agreement of the spatial patterns. Concerning the absolute values, OMI data are, on average, higher than the car MAX-DOAS observations close to strong emission sources, and vice versa over less polluted regions. Our results indicate that OMI NO2 VCDs are biased low over strongly polluted regions, probably caused by inadequate a-priori profiles used in the OMI satellite retrieval

An Investigation on the Morphological and Mineralogical Characteristics of Posidonius Floor Fractured Lunar Impact Crater Using Lunar Remote Sensing Data

Lunar floor‐fractured craters (FFCs) are a distinguished type of crater found on the surface of the Moon with radial, concentric, and/or polygonal fractures. In the present study, we selected the Posidonius FCC to explore the mineralogy, morphology and tectonic characteristics using remote sensing datasets. The Posidonius crater is vested with a wide moat of lava separating the crater rim inner wall terraces from the fractured central floor. Lunar Reconnaissance Orbiter’s (LRO) images and Digital Elevation Model (DEM) data were used to map the tectonics and morphology of the present study. The Moon Mineralogy Mapper (M3) data of Chandrayaan‐1 were used to inves-tigate the mineralogy of the region through specified techniques such as integrated band depth, band composite and spectral characterization. The detailed mineralogical analysis indicates the nor-itic‐rich materials in one massif among four central peak rings and confirm intrusion (mafic pluton). Spectral analysis from the fresh crater of the Posidonius moat mare unit indicates clinopyroxene pigeonite in nature. Integrated studies of the mineralogy, morphology and tectonics revealed that the study region belongs to the Class‐III category of FFCs. The lithospheric loading by adjacent volcanic load (Serenitatis basin) generates a stress state and distribution of the fracture system

Role of Automation in Energy Management and Distribution

951-954This paper discusses about how automation plays its role in achieving sustainable energy management in broadly two aspects, industries and homes. Industrial or factory automation has its own benefits, and techniques have been evolved to cut down the power usage to significant levels of the conventional ways using Variable Frequency Drives (VFD). Home automation is equally important, controlling electrical appliances through microcontrollers and saving electricity automatically detecting their usage needs. It also discusses about the requisites for energy management and the economic aspect of using energy management systems
