    Watershed programme is an important intervention in dryland areas to improve livestock productivity through increased feed and fodder supply. The present study has focused on the impact of watershed interventions on crop-livestock linkages with particular emphasis on how the interventions have affected the quantity of stovers/straws as livestock feeding materials in bridging the demand-supply gap. The study has been carried out in three typical Shivalik foothill watersheds (two treated and one untreated) in the Panchkula district of Haryana state. The impact of watershed development programme has been estimated by adopting both with and without approach and before and after approach. The untreated watershed has derived 65 per cent of its total income from animal husbandry. On the contrary, this sector has contributed 42 per cent and 20 per cent in two treated watersheds. The availability of supplemental irrigation enabled the villagers to step up cropping intensity. The number of goats has reduced considerably in both treated watersheds and the number of stall-fed buffaloes has increased. Adult cattle units per household and per hectatre of cultivated area have been found to be highest in the untreated watershed. Green and dry fodder availability, both from cultivated lands and forest area, has increased as a result of implementation of watershed programme. Although the gap between requirement and availability has narrowed down in both the treated watersheds, significant gains could be realized in Sambhalwa watershed due to sufficient water availability to all the households. Bunga watershed has also shown effectiveness of watershed development programme in reducing demand –supply gap of fodder. This gap, however, widened after reaching the saturation point of watershed programme, i.e. after 22 years of its implementation.Fodder, Demand-supply gap, Watershed management, Livestock production, Shivaliks, Agricultural and Food Policy, Q01, Q15, Q25, Q28,

    Expression of CDR1, a multidrug resistance gene of Candida albicans: transcriptional activation by heat shock, drugs and human steroid hormones

    We have examined the expression of CDR1 (Candida drug resistance gene) in different stress conditions. There was a significant but transient enhancement of CDR1 expression associated with elevated temperatures. Most noteworthy transcriptional activation was observed with miconazole and vinblastine. Interestingly, ÎČ-estradiol and progesterone were also able to enhance CDR1 expression. Elevated levels of CDR1 and CDR2 (a homologue of CDR1) mRNA were found in some azole-resistant clinical isolates of C. albicans. CaMDR1 (benomyl-resistant) expression, however, did not differ among all the resistant isolates. Our results confirm the existence of multiple mechanisms of azole resistance in C. albicans

    Short-period variable stars in young open cluster Stock 8

    Get PDF
    We present time-series photometry in the field of Stock 8 and identified 130 short-period variable stars. Twenty-eight main-sequence and 23 pre-main-sequence variables are found to be part of cluster Stock 8. The main-sequence variables are classified as slow pulsators of the B-type, ÎČ Cep, and ÎŽ Scuti stars. Fourteen main-sequence stars could be new class variables as discussed by Mowlavi et al. and Lata et al. The age and mass of pre-main-sequence variables are found to be lesssim5 Myr and in the mass range of 0.5–2.8 M ⊙, respectively. These pre-main-sequence stars could be T-Tauri variables. We have found 5 and 2 of 23 pre-main-sequence variables as classical T-Tauri stars and Herbig Ae/Be stars, respectively, whereas 16 pre-main-sequence stars are classified as weak-line T-Tauri stars

    Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

    Get PDF
    A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe
