agriculture is an important engine of growth and poverty reduction in much of africa, nigeria inclusive. but the sector is underperforming in part because women, who are often crucial resource in agriculture and rural economy, face constraints that reduce their productivity. an understanding of these constraints is a prerequisite to devising policies to improve agricultural production and produ...

this study assessed of youth involvement in agricultural production in sabon gari local government area. the data used for this study were collected using interview schedule administered to 112 respondents who were selected through multi-stage sampling procedure. descriptive statistics such as frequency, percentages and means were used to analyze the data. the result revealed that majority (95....

teleworking as an innovative way has many benefits in governmental, organizational and individual levels, but it faced with different variables in plan and implementation which is caused to low acceptance rate in organizations. by identifying and controlling these variables, managers and decision-makers can use teleworking programs in their organizations. the aim of this study is to investigate...

We present a bottom-up approach to the problem of fixing psychological requirements to concept possession. It is argued that four constraints are required: abstraction, directedness, multimodality and off-line processing. Taken together, these psychological requirements yield a view of concepts similar (on certain aspects) to “dual” philosophical pictures: both inferential role and referential ...

We constrain the properties of the progenitor system of the highly reddened Type Ia supernova (SN Ia) 2014J in Messier 82 (M82; d ≈ 3.5 Mpc). We determine the supernova (SN) location using Keck-II K-band adaptive optics images, and we find no evidence for flux from a progenitor system in pre-explosion near-ultraviolet through near-infrared Hubble Space Telescope (HST) images. Our upper limits e...

Metabolic fluxes are governed by physical and economic principles. Stationarity constrains them to a subspace in flux space and thermodynamics makes them lead from higher to lower chemical potentials. At the same time, fluxes in cells represent a compromise between metabolic performance and enzyme cost. To capture this, some flux prediction methods penalise larger fluxes by heuristic cost terms...

The yield of sugar beet has continuously increased in the past decades. The question arises, whether this progress will continue in the future. A key factor for increasing yield potential of the crop is breeding progress. It was related to a shift in assimilate partitioning in the plant toward more storage carbohydrates (sucrose), whereas structural carbohydrates (leaves, cell wall compounds) u...

A wide range of problems can be modelled as constraint satisfaction problems (CSPs), that is, a set of constraints that must be satisfied simultaneously. Constraints can either be represented extensionally, by explicitly listing allowed combinations of values, or implicitly, by special-purpose algorithms provided by a solver. Such implicitly represented constraints, known as global constraints,...
