Acetonitriledicarbonyl (η5pentamethylcyclopentadienyl) iron (II) tetrafluoridoborate
(International Union of Crystallography, 2011)In the structure of the title compound, [Fe{5C5(CH3)5} (NCCH3)(CO)2]BF4, the arrangement of ligands around the Fe atom is in a pseudooctahedral threelegged pianostoolfashion in which the pentamethylcyclopentadienyl ... 
Adaptive nonparametric variance estimation for a ratio estimator
(Jomo Kenyatta University of Agriculture and Technology (JKUAT), 1997) 
Assessment of Zinc Intake, Status and Influencing Factors in Kenya
(2015)Zinc (Zn) is vital for many biological functions and plays a crucial role in more than 300 enzymes in the human body (Brown & Wuehler 2002). The risk ... 
Bayesian Estimation of Survivor Function for Censored Data Using Lognormal Mixture Distributions
(IOSR Journal of Mathematics, 2017)We use Bayesian methods to fit a lognormal mixture model with two components to right censored survival data to estimate the survivor function. This is done using a simulationbased Bayesian framework employing a prior ... 
Bias Correction Technique for Estimating Quantiles of Finite Populations under Simple Random Sampling without Replacement
(Open Journal of Statistics, 202110)In this paper, the problem of nonparametric estimation of finite population quantile function using multiplicative bias correction technique is considered. A robust estimator of the finite population quantile function based ... 
Bias Reduction Technique for Estimating Finite Population Distribution Function under Simple Random Sampling without Replacement.
(International Journal of Statistics and Applications, 2018)The problem of nonparametric estimation of finite population distribution function using multiplicative bias correction technique is considered in this paper. A robust estimator of the finite population distribution function ... 
Biochemical Characterization of Allene Oxide Synthases from the Liverwort Marchantia Polymorpha and Green Microalgae Klebsormidium Flaccidum Provides Insight into the Evolutionary Divergence of the Plant CYP74 Family
(Springer Berlin Heidelberg, 2015)Allene oxide synthase (AOS) and hydroperoxide lyase (HPL) mediate the formation of precursors of jasmonates and carbonsix volatiles, respectively. AOS and HPL utilize fatty acid hydroperoxides and belong to the plant ... 
Characterization of Composite Material from the Copolymerized Polyphenolic Matrix with treated Cassava Peels Starch
(Elsevier, 2020)Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has not ... 
Chloride Diffusivity in Blended Cement Made from Selected Industrial and Agrowastes
(Hindawi, 2020)This paper reports study findings on the diffusivity of chloride ions in potential blended cement. The cement, abbreviated as PCDC, was made from blending ordinary Portland cement (OPC) with dried calcium carbide residue ... 
Chloride Ingress in Chemically Activated Calcined ClayBased Cement
(Elsevier, 2018)Chlorideladen environments pose serious durability concerns in cement based materials. This paper presents the findings of chloride ingress in chemically activated calcined ClayOrdinary Portland Cement blended mortars. ... 
CLASSICAL CONSTRUCTION OF ANGLES IN GENERAL
(International Journal of Mathematical Archive, 2016)The construction of angles in general is a classical problem in mathematics. The early mathematicians failed to redress the problem under the stated restrictions because they did not have a bearing to approach the problem ... 
CLASSIFICATION RATES: NONPARAMETRIC VERSES PARAMETRIC MODELS USING BINARY DATA
(Journal of Agriculture, Science and Technology, 2014)Estimations of the conditional mean and the marginal effects for particular small changes in the covariates have been of interest in financial, economics and even educational sectors. The standard approach has been to ... 
Comparison of some Panel Data Regression Model Estimators using Simulated Data
(JKUAT, 2016)This paper presents estimation of panel data regression models with individual effects. We discuss estimation techniques for both fixed and random effects panel data regression models. We derive twostage least squares and ... 
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... 
Control of the polarization direction of isolated attosecond pulses using inhomogeneous twocolor fields
(Nature Publishing Group, 2019)We theoretically demonstrate the control of the polarization direction of isolated attosecond pulses (IAPs) with inhomogeneous twocolor fields synthesized by an 800nm fundamental pulse and a 2000 nm control pulse having ... 
The Cube Duplication Solution (A Compassstraightedge (Ruler) Construction)
(International Journal of Mathematics Trends and Technology, 2017)This paper objectively presents a provable construction of generating a length of magnitude;, as the geometrical solution for the ancient classical problem of doubling the volume of a cube. Cube duplication is believed to ... 
Defectinduced room temperature ferromagnetic properties of the Aldoped and undoped ZnO rodlike nanostructure
(Elsevier, 2017)In this work, electron paramagnetic resonance (EPR) experiment on undoped ZnO and Al doped ZnO (AZO) nanoparticles prepared by facile sol–gel method were investigated. The effects of the Al concentration on room temperature ... 
Deriving Penalized Splines For Estimation Of Time Varying Effects In Survival Data
(International Journal of Scientific & Technology Research, 2014)The major interests of survival analysis are either to compare the failure time distribution function or to assess the effects of covariate on survival via appropriate hazards regression models. Cox’s proportional hazards ...
