    The primary goal of this digital educational platform is to deliver high-quality educational possibilities to people looking for a degree or similar graded programs, tuition classes, and postgraduate programs provided by universities internationally and nationally. Furthermore, by advertising on our web platform, educational institutions will be able to improve the popularity of their courses and services.  There will also be the opportunity to donate financial contributions to campaigns or organizations that will help persons in need of educational assistance. In addition, our development team proposed an idea about a component called volunteer support, which allows users to join up as volunteers for specific organizational initiatives that promote educational campaigns. There will also be several account types for system administrators, users searching for services, and organizations promoting educational programs and volunteer opportunities. The account's capabilities differ depending on the type of user account. The primary objectives of this thesis are to provide the concept of a system that simplifies the process of locating and advertising educational needs, opportunities, and services while providing a way to help people in need of a helping hand

    Chickpea Baseline and Early Adoption Surveys in South Asia Insights from TL-II (Phase-I) Project: Synthesis Report 2013

    Chickpea is one of the most important pulse crops in India. Its area reached a peak at the beginning of the green revolution in the country, but rapid strides in wheat productivity have encouraged farmers in north-western India to substitute wheat for chickpea, causing a fall in its area and production. Nevertheless, the crop soon found a new home in the central and southern states of the country. It was a big challenge for the chickpea scientists in India’s national program and at the International Crops Research Institute for the Semi-arid Tropics (ICRISAT) to breed short duration but high yielding varieties and develop a package of practices suitable to the warmer growing conditions. Very soon, the crop recovered area as well as production on the back of rising productivity. For ICRISAT, the generous support received from the Bill & Melinda Gates Foundation (BMGF) was an excellent opportunity to work with its research and development partners in India to accelerate the productivity growth by following the strategy of Farmer Preferred Varietal Selection (FPVS). This approach shortens the time needed to popularize the new varieties by exposing them to farmers and by backing up the varieties preferred by the farmers through intensive seed production efforts. This report documents the rapid strides made in taking the new varieties to the farmers by the FPVS process, and producing and supplying the seeds of varieties preferred by them during 2007-10

    Using a data sample of 980 fb1^{-1} collected with the Belle detector operating at the KEKB asymmetric-energy e+^{+}e^{-} collider, we present evidence for the Ω(2012)^{-} in the resonant substructure of Ωc_{c}0^{0} → π+^{+} (K\overline{K} Ξ)^{-} ((K\overline{K} Ξ)^{-} = K^{-}Ξ0^{0} + K0^{0}Ξ^{-} ecays. The significance of the decays. The significance of the Ω(2012)^{-} signal is 4.2σ after considering the systematic uncertainties. The ratio of the branching fraction of Ωc_{c}0^{0} → π+^{+} Ω(2012)^{-} π+^{+} (K\overline{K} Ξ)^{-} relative to that of Ωc_{c}0^{0} → π+^{+} Ω^{-} is calculated to be 0.220±0.059(stat.)±0.035(syst.). The individual ratios of the branching fractions of the two isospin modes are also determined and found to be B (Ωc_{c}0^{0} → π+^{+} Ω(2012)^{-}) x B(Ω(2012)^{-}K\overline{K} Ξ0^{0}) / B(Ωc_{c}0^{0} → π+^{+} K^{-}Ξ0^{0} = (9.6±3.2(stat.) ±1.8(syst.))% and B (Ωc_{c}0^{0} → π+^{+} Ω(2012)^{-}) x B(Ω(2012)^{-}K\overline{K}0^{0} Ξ^{-}) / B(Ωc_{c}0^{0} → π+^{+} K\overline{K}0^{0}Ξ^{-}) =(5.5±2.8(stat.) ±0.7(syst.))

    Based on a data sample of 983 fb1^{-1} collected with the Belle detector at the KEKB asymmetric-energy e+ee^+e^- collider, we present the study of the heavy-flavor-conserving decay Ξc0Λc+π\Xi_{c}^{0}\to \Lambda_{c}^{+}\pi^{-} with Λc+\Lambda_{c}^{+} reconstructed via its pKπ+pK^{-} \pi^{+} decay mode. The branching fraction ratio B(Ξc0Λc+π)/B(Ξc0Ξπ+)\mathcal{B}(\Xi_{c}^{0}\to \Lambda_{c}^{+}\pi^{-})/\mathcal{B}(\Xi_{c}^{0}\to \Xi^{-}\pi^{+}) is measured to be 0.38±0.04±0.040.38 \pm 0.04 \pm 0.04. Combing with the world average value of B(Ξc0Ξπ+)\mathcal{B}(\Xi_{c}^{0}\to \Xi^{-}\pi^{+}), the branching fraction B(Ξc0Λc+π)\mathcal{B}(\Xi_{c}^{0}\to \Lambda_{c}^{+}\pi^{-}) is deduced to be (0.54±0.05±0.05±0.12)%(0.54 \pm 0.05 \pm 0.05 \pm 0.12)\%. Here, the uncertainties above are statistical, systematic, and from B(Ξc0Ξπ+)\mathcal{B}(\Xi_c^{0} \to \Xi^{-}\pi^{+}), respectively.Comment: 5 pages, 4 figure

    We report branching fraction measurements of four decay modes of the Λc+\Lambda_{c}^{+} baryon, each of which includes an η\eta meson and a Λ\Lambda baryon in the final state, and all of which are measured relative to the Λc+pKpi+\Lambda_{c}^{+} \rightarrow p K^{-} pi^{+} decay mode. The results are based on a 980 fb1980~\mathrm{fb^{-1}} data sample collected by the Belle detector at the KEKB asymmetric-energy e+ee^{+}e^{-} collider. Two decays, ηΣ0π+\eta \Sigma^{0} \pi^{+} and Λ(1670)π+\Lambda(1670) \pi^{+}, are observed for the first time, while the measurements of the other decay modes, Λc+ηΛπ+\Lambda_{c}^{+} \rightarrow \eta\Lambda\pi^{+} and ηΣ(1385)+\eta\Sigma(1385)^{+}, are more precise than those made previously. We obtain B(Λc+ηΛπ+)/B(Λc+pKπ+)\mathcal{B}(\Lambda_{c}^{+} \rightarrow \eta \Lambda \pi^{+})/\mathcal{B}(\Lambda_{c}^{+} \rightarrow p K^{-} \pi^{+}) = 0.293±0.003±0.0140.293 \pm 0.003 \pm 0.014, B(Λc+ηΣ0π+)/B(Λc+pKπ+)\mathcal{B}(\Lambda_{c}^{+} \rightarrow \eta \Sigma^{0} \pi^{+})/\mathcal{B}(\Lambda_{c}^{+} \rightarrow p K^{-} \pi^{+}) = 0.120±0.006±0.0060.120 \pm 0.006 \pm 0.006, B(Λc+Λ(1670)π+)×B(Λ(1670)ηΛ)/B(Λc+pKπ+)\mathcal{B}(\Lambda_{c}^{+} \rightarrow \Lambda(1670) \pi^{+}) \times \mathcal{B}(\Lambda(1670) \rightarrow \eta \Lambda)/\mathcal{B}(\Lambda_{c}^{+} \rightarrow p K^{-} \pi^{+}) = (5.54±0.29±0.73)×102(5.54 \pm 0.29 \pm 0.73 ) \times 10^{-2}, and B(Λc+ηΣ(1385)+)/B(Λc+pKπ+)\mathcal{B}(\Lambda_{c}^{+} \rightarrow \eta \Sigma(1385)^{+})/\mathcal{B}(\Lambda_{c}^{+} \rightarrow p K^{-} \pi^{+}) = 0.192±0.006±0.0160.192 \pm 0.006 \pm 0.016.
