Drought and heat stress have become the most prevailing problems for maize (Zea mays L.) crop production. Therefore, development of tolerance has an essential goal in a breeding programme. Hence, experiment was conducted at Punjab Agricultural University, Ludhiana, to identify tolerant DH lines during spring season, 2016 2017. A total 32 were evaluated under non-stress conditions. Five indices ...
The primordial abundance of He, YP , is one of the hottest themes in present-day astronomy, mostly due to its cosmological relevance. The disagreement between different determinations has been currently reduced to the 1-2% level, but these differences are still large enough to have deep implications for Big-Bang nucleosynthesis. It is therefore crucial to estimate precisely the uncertainties in...
x1 = t1(x1, . . . , xn, y1, . . . yp) .. (1) xn = tn(x1, . . . , xn, y1, . . . yp), where, typically, for each i ∈ [n], ti denotes a function ti : A → A, for some structure A. Sometimes, the structure A is equipped with a partial order, and the functions ti are order-preserving or continuous. In such a case, for a given p-tuple of elements y1, . . . , yp in A, one might ask for the least x1, . ...
We revisit the constraint on the primordial helium mass fraction Yp from observations of cosmic microwave background (CMB) alone. By minimizing χ of recent CMB experiments over 6 other cosmological parameters, we obtained rather weak constraints as 0.17 ≤ Yp ≤ 0.52 at 1σ C.L. for a particular data set. We also study the future constraint on cosmological parameters when we take account of the pr...
The IEEE Power Electronics Society (PELS) Students and Young Professionals (S&YP) Committee launched a new initiative in July 2023; the PELS S&YP Spotlight Program. goals of this spotlight program lie at core committee’s mission, which is to support engagement development students early career engineers PELS. By highlighting work accomplishments members, aims connect organizational committee wi...
Approximately two thirds of migratory songbirds in eastern North America negotiate the Gulf of Mexico (GOM), where inclement weather coupled with no refueling or resting opportunities can be lethal. However, decisions made when navigating such features and their consequences remain largely unknown due to technological limitations of tracking small animals over large areas. We used automated rad...
We studied the regulation of the yolk protein (YP) genes in the somatic cells of the gonads, using temperature sensitive mutations (tra-2ts) of transformer-2, a gene required for female sexual differentiation. XX;tra-2ts mutant animals were raised at the permissive temperature so that they developed as females and were then shifted to the restrictive male-determining temperature either 1-2 days...
Finishing precocity visual score selection was adopted to estimate the time from birth to reach slaughter age. This study estimated (co)variance components and genetic correlations for the finishing precocity score at weaning (WP) and yearling (YP) stages by using daily weight gain (BWG = from birth to weaning; WYG = from weaning to yearling) and speed of weight gain (BWR = from birth to weanin...
Humoral and cellular immune response of mice challenged with Yersinia pestis antigenic preparations.
OBJECTIVES The plague, which is an infectious disease caused by Yersinia pestis, still threatens many populations in several countries. The worldwide increase in human plague cases and the potential use of the bacteria as a biological weapon reinforce the need to study the immunity that is induced by potential vaccine candidates. To determine the immunogenicity of antigenic preparations based o...
