        Biology of Menochilus sexmaculatus Fab. and Coccinella undecimpunctata L.(Coccinellidae: Coleoptera) on Alfalfa Aphid Therioaphis trifolii Monell

        J.M., Mari.,Nizamani, S.M.,Lohar, M.K.,Khuhro, R.D. Korean Society of Applied Entomology 2004 Journal of Asia-Pacific Entomology Vol.7 No.3

        Biology of Menochilus sexmaculatus Fab. and Coccinella undecimpunctata L. on alfalfa aphid Therioaphis trifolii Monell were investigated during winter season at Tando Jam, Sindh, Pakistan. The latent period of M. sexmaculatus was 31.7$\pm$0.3 and C. undecimpunctata 6.7$\pm$0.1 seconds. Duration of copulation in M. sexmaculatus and C. undecimpunctata were 81.8$\pm$5.4 and 64.5$\pm$6.1 minutes. The oviposition and post-oviposition period of M. sexmaculatus, were 27.4$\pm$4.1 and 4.5$\pm$0.3 days and C. undecimpunctata, were 19.9$\pm$5.2 and 3.8$\pm$0.4 days. Fecundity per female was observed 602$\pm$75.3 for M. sexmaculatus and 761$\pm$85.2 for C. undecimpunctata. The mean egg periods of M. sexmaculatus and C. undecimpunctata were 8.6$\pm$1.2 and 7.3$\pm$1.0 days. Larval duration for first, second, third and fourth instars of M. sexmaculatus were 7.3$\pm$0.6, 4.3$\pm$0.2, 3.8$\pm$0.3 and 6.7$\pm$1.1 days. The pupal period of M. sexmaculatus was 3.6$\pm$0.3 and C. undecimpunctata was 5.1$\pm$0.5 days. The adult period of M. sexmaculatus, (female and male) under this study was 34.9$\pm$4.8 and 29.7$\pm$1.2 days.

        Black Carbon Concentration during Spring Season at High Altitude Urban Center in Eastern Himalayan Region of India

        Khushboo Sharma,Rakesh Kumar Ranjan,Sargam Lohar,Jayant Sharma,Rajeev Rajak,Aparna Gupta,Amit Prakash,Alok Kumar Pandey 한국대기환경학회 2022 Asian Journal of Atmospheric Environment (AJAE) Vol.16 No.1

        This study analyzed the BC associated with PM1 and the contribution of biomass burning to the BC using a portable seven-channel Dual spot Aethalometer in and around Gangtok, the capital city of Sikkim, India, during April 2021. Additionally, CO2 and meteorological parameters (Temperature, Pressure, and Relative Humidity) was measured. The minimum concentration of BC was found in rural areas where the contribution of biomass burning to the BC is highest. The observed spatial variability of BC over Gangtok Municipal Corporation (GMC) area is minimal. Five days back-trajectory analysis was done using the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model to understand the regional influences of air masses at Gangtok. The air mass of the studied region is under influence of trans-regional transport from Indo-Gangetic Plains affecting the BC concentration over the studied region. The black carbon presence in the ambient air near the glacier heights in the Eastern Himalayan region may significantly cause localized warming, thereby enhancing glacier melts. The results have significant bearing for the policy-makers to take corrective steps in addressing the issue of rising BC concentration in high altitude regions. A further detailed study is needed to examine the effect of BC on radiative forcing and its large-scale effect on the East Asian summer monsoon using regional climate models.

        Baking impact of Fe composition on CdSe films for solar cell application

        Shinde, S.K.,Dubal, D.P.,Ghodake, G.S.,Lee, D.S.,Lohar, G.M.,Rath, M.C.,Fulari, V.J. North-Holland 2014 Materials letters Vol.132 No.-

        Cd<SUB>1-X</SUB>Fe<SUB>X</SUB>Se thin films were electrodeposited onto fluorine doped tin oxide coated conducting glass (FTO) and stainless steel (SS) substrates at various bath compositions with X=0.1 to 0.5 in an aqueous electrolytic bath containing CdSO<SUB>4</SUB>, FeSO<SUB>4</SUB> and SeO<SUB>2</SUB>. The effects of different compositions on physico-chemical properties of Cd1-XFeXSe thin films have been systematically investigated. The X-ray diffraction (XRD) analysis reveals the polycrystalline in nature of Cd<SUB>1-X</SUB>Fe<SUB>X</SUB>S thin films. Field emission scanning electron microscopy (FE-SEM) micrographs shows the variation in the nanostructure with varying compositions. The Cd<SUB>1-X</SUB>Fe<SUB>X</SUB>Se thin films exhibited the water contact angles in hydrophilic range. Optical absorption measurements are used to estimate the band gap value of Cd<SUB>1-X</SUB>Fe<SUB>X</SUB>Se thin films deposited at various bath compositions. The dramatic changes in surface morphology, as a consequence of different composition of Fe in CdSe matrix, significantly alter the conversion efficiency of Cd<SUB>1-X</SUB>Fe<SUB>X</SUB>Se films.

        Biology of Menochilus sexmaculatus Fab. and Coccinella undecimpunctata L. on alfalfa aphid Therioaphis trifolii Monell were investigated during winter season at Tando Jam, Sindh, Pakistan. The latent period of M. sexmaculatus was 31.7±0.3 and C. undecimpunctata 6.7±0.1 seconds. Duration of copulation in M. sexmaculatus and C. undecimpunctata were 81.8±5.4 and 64.5±6.1 minutes. The oviposition and post-oviposition period of M. sexmaculatus, were 27.4±4.1 and 4.5±0.3 days and C. undecimpunctata, were 19.9±5.2 and 3.8±0.4 days. Fecundity per female was observed 602±75.3 for M. sexmaculatus and 761±85.2 for C. undecimpunctata. The mean egg periods of M. sexmaculatus and C. undecimpunctata were 8.6±1.2 and 7.3±1.0 days.
