Coming of age: steroid hormones of wild immature baboons, Papio cynocephalus.
(2005)Large gaps exist in our knowledge about common patterns and variability in the endocrinology of immature nonhuman primates, and even normal hormonal profiles during that life stage are lacking for wild populations. In the ... -
Persistence of maternal effects in baboons: Mother's dominance rank at son's conception predicts stress hormone levels in subadult males
(Academic Press, 2008-07-01)Dominance status and reproductive experience are maternal characteristics that affect offspring traits in diverse taxa, including some cercopithecine primates. Maternal effects of this sort are widespread and are sources ... -
Life history context of reproductive aging in a wild primate model
(Blackwell Publishing Inc, 2010-08-01)The pace of reproductive aging has been of considerable interest, especially in regard to the long postreproductive period in modern women. Here we use data for both sexes from a 37‐year longitudinal study of a wild baboon ... -
Balance of investment between parental care and mating effort in male baboons
(2011)Non-monogamous males that provide care to their offspring face a potential conflict in investment between paternal care and mating effort. This conflict arises either because of resource or temporal constraints. I ... -
Testosterone positively associated with both male mating effort and paternal behavior in savanna baboons (Papio cynocephalus)
(Academic Press, 2013-03-31)Testosterone (T) is often positively associated with male sexual behavior and negatively associated with paternal care. These associations have primarily been demonstrated in species where investment in paternal care begins ... -
Puberty and dispersal in a wild primate population
(Academic Press, 2013-07-01)This article is part of a Special Issue “Puberty and Adolescence”. The onset of reproduction is preceded by a host of organismal adjustments and transformations, involving morphological, physiological, and behavioral ... -
Demography of a population with a long history of poaching and the utility of the individual identification technique as a tool for monitoring intermittently studied elephant populations
(2016-09-01)In many elephant populations in Africa, adverse effects of poaching including altered age and sex structure and long calving intervals continue to negatively impact the rate of recovery. The study reported here characterized ... -
Hormonal correlates of natal dispersal and rank attainment in wild male baboons
(Academic Press, 2017-08-01)In many mammals, maturational milestones such as dispersal and the attainment of adult dominance rank mark stages in the onset of reproductive activity and depend on a coordinated set of hormonal and socio-behavioral ... -
A numerical thermal growth model for prediction of microalgae production in photobioreactors
(AIP Publishing, 2016-03)A thermal growth model for microalgae that are not heavier than water with the consideration of heat transfer and growth-temperature dependence in photobioreactor (PBR) is developed. The microalgae growth performance is ... -
HYDRODYNAMIC ANALYSIS OF A FIXED INCLINE SLIDER BEARING
(2016-05-23)In the present day technological scenario, machines rotating at high speeds and carrying heavy rotor loads are used. As a result, fixed incline slider bearings are used. They are designed for high axial loads. When a bearing ... -
On the Solution of n-Dimensional Regular Cauchy Problem of Euler-Poisson-Darboux Equation (EPD)
(2017)A general exact solution to the n-dimensional regular Cauchy prob- lem of Euler-Poisson-Darboux (EPD) equation has been studied. Firstly, the general exact solution for the one dimensional regular Cauchy prob- lem of ... -
An investigation of MHD Flows of Nanofluid over an oscillating surface with Joule Heating
(International Scientific Press, 2017)The present study aims at investigating unsteady hydromagnetic flow of viscous incompressible, conducting nanofluid over an infinite oscillating surface with Joule heating. The governing equations involved are transformed ... -
Similarity Transformation Analysis of Heat and Mass Transfer Effects on Steady Buoyancy Induced MHD Free Convection Flow Past an Inclined Surface
(2017)The present work is devoted to the problem of a steady two di- mensional hydromagnetic convective ow of a viscous, incompressible electrically conducting uid past an inclined semi-in nite plate in the presence of ... -
Numerical Computation of Steady Buoyancy Driven MHD Heat and Mass Transfer Past An Inclined Infinite Flat Plate with Sinusoidal Surface Boundary Conditions
(2007)In this paper we study the e ects of magnetohydrodynamics (MHD) uid ow on a two dimensional boundary layer ow of a steady free convection heat and mass transfer on an inclined plate in which the angle of inclination ... -
Numerical Solution of Non-Linear Boundary Value Problems of Ordinary Differential Equations Using the Shooting Technique
(2017)Ordinary Di erential Equations (ODEs) of the Initial Value Problem (IVP) or Boundary Value Problem (BVP) type can model phenomena in wide range of elds including science, engineering, economics, social science, biology, ... -
The effect of cultivation techniques on tea quality

Flavanol Composition and Caffeine Content of Green Leaf as Quality Potential Indicators of Kenyan Black Teas
(1997)The Ñavanol composition and ca†eine content of green tea leaf, black tea quality parameters of theaÑavins, thearubigins, liquor brightness and total colour varied more among clones than with time of the year. In green ... -
Response of some black tea quality parameters to nitrogen fertiliser rates and plucking frequencies
(John Wiley & Sons, Ltd, 1994-12-01)The effects of the rate of application of nitrogenous fertiliser and frequency of plucking (harvesting) on various black tea quality parameters and yields were compared on done 6/8. High rates of nitrogen application and ...
