Silage Quality of Sorghum Harvested at Different Times and Its Combination with Mixed Legumes or Concentrate Evaluated in Vitro [PDF]

open access: yes, 2016
The experiment was designed to evaluate the silage quality of sorghum forage varieties of Citayam and BMR 3.6 strain at different harvesting times and the effectiveness of a legumes addition as a concentrate substitute in sorghum forage silage-based ...

Wage Dispersion in a Partially Unionized Labor Force [PDF]

open access: yes
Taking as our point of departure a model proposed by David Card (2001), we suggest new methods for analyzing wage dispersion in a partially unionized labor market.

Desempenho de biomassas na adsorção de hidrocarbonetos leves em efluentes aquosos Performance of biomasses in the adsorption of simple hydrocarbons in aqueous effluents

open access: yesQuímica Nova, 2007
Removal of hydrocarbons from aqueous effluents using biosorbents was investigated. The effluent was simulated by a dispersion of gasoline (simple hydrocarbons) in water.

Optimisation of future long baseline neutrino experiments [PDF]

open access: yesarXiv, 2008
The aim of this talk is to review near and far future long baseline neutrino experiments as superbeams, beta-Beams and neutrino factories, comparing their sensitivities to the unknown parameters in the neutrino oscillation sector. We focus on the extraction of the neutrino mass hierarchy, exploring alternatives to the commonly used neutrino ...

Planejamento fatorial e superfície de resposta: otimização de um método voltamétrico para a determinação de ag(i) empregando um eletrodo de pasta de nanotubos de carbono

open access: yesQuímica Nova, 2011
A factorial design applied in a voltammetric stripping method for the measurement of Ag(I) in natural water is described. The procedure is based on the effective pre-concentration of silver ions on electrode surface.

Invariance of generalized wordlength patterns

open access: yes, 2008
The generalized wordlength pattern (GWLP) introduced by Xu and Wu (2001) for an arbitrary fractional factorial design allows one to extend the use of the minimum aberration criterion to such designs. Ai and Zhang (2004) defined the $J$-characteristics of

Generation of Factorial Designs

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1976
Summary This paper describes a method for generating asymmetrical factorial designs given specified relationships between the levels of treatment and plot factors. Comparisons are made with a generalized cyclic method (John and Dean, 1975) for single replicate designs.

Development and characterization of microemulsion containing antihypertensive agent using factorial design

open access: yesJournal of Pharmacy and Bioallied Sciences, 2012
Microemulsion which act as a carrier for drug having poor water solubility, were formulated by the use of excipients having safety of administration and solubility of drug component. The phase study was carried out using isopropyl myristate, cremophor-el,
