Farmers can only be market oriented if his/her production plan follows market signals and produce commodities that is more marketable. In other to achieve this, this study provided empirical evidence on the Gender analyses of market orientation in South Eastern, Nigeria. A stratified sampling design was used to select 360 sample respondents in 2017. Market Orientation Index (MOI) and Heckit sel...

integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical co2 as a nonsolvent for the polymer solution. in present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. it is shown that the presence of silica nanoparticles not only di...

the influence of mo particle size on the catalytic activity and product selectivity of alkalized mos2 nanocatalysts has been investigated. nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. three different techniques, including xrd, tem, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

using surface analysis, simultaneous effects of temperature (260-380ºc) and ethanol concentration (0-1%) on dimethyl ether (dme) selectivity, yields of hydrocarbon and dme, and methanol conversion were investigated in methanol dehydration reaction over γ-al2o3 catalyst. methanol conversion and yield of hydrocarbon/dme were found to be significantly affected by temperature and the temperature-et...

the oxidative coupling of methane (ocm) performance over na-w-mn/sio2 at elevated pressures has been simulated by adaptive neuro fuzzy inference system (anfis) using reaction data gathered in an isothermal fixed bed microreactor. in the designed neuro fuzzy models, three important parameters such as methane to oxygen ratio, gas hourly space velocity (ghsv), and reaction temperature were conside...

I specify an econometric model to estimate the causal effects of environmental factors on individuals’ life-cycle health outcome, and outline a semiparametric control function approach to test and correct for the possible selectivity bias that may arise due to endogenous choice of residence by individuals. I show how to map Union Army Sample data to elements of this model in practice. JEL Class...

The influence of Mo particle size on the catalytic activity and product selectivity of alkalized MoS2 nanocatalysts has been investigated. Nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. Three different techniques, including XRD, TEM, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

Peer reviewing of papers is the mainstay of modern academic publishing but it has well known problems. In this paper, we take a statistical modelling view to show a particular problem in the use of selectivity measures to indicate the quality of a conference. One key problem with the process of conference reviewing is the failure to make a useful feedback loop between the referees of the papers...

Both environmental and genetic factors interact to produce the orientation maps found in the primary visual cortex of adult mammals. However, it is not clear how this interaction occurs during development, or whether both factors are crucial. Previous computational models have focused on either environmentally driven or genetically driven development alone. In contrast, we show that a two-stage...
