Spatiotemporal correlations in start-up flows of attractive colloids are explored by numerical simulations as a function of their volume fraction and shear rate. The suspension is first allowed to flocculate during a time tw, then the stress necessary to induce its flow is computed. We find that, at low volume fractions, the stress is a universal function of the strain. On the contrary, at high...

beekeeping as a technology package disseminated to target farmers in nigeria seems to suffer setbacks ranging from negative perception of farmers about the technology to technical contents of the package. this study therefore analyzes the technology attributes that influence non adoption of apiary technology packages in cross river state, nigeria. purposive and multistage random sampling techni...

the study assessed the post-harvest management information needs of yam farmers in kogi state. interview schedules were used to collect data from 189 yam farmers who were randomly selected from the four agricultural zones of the state (zone a, b, c and d) by using multistage random sampling techniques. the data collected were subjected to descriptive statistics and binary logit regression. resu...

the goal followed in this study was to investigate the barriers that hinder the application of mobile phone technology being communication in agricultural education, from the view points of agricultural extension educators of ardabil province. survey research method was used throughout the study. the line and staff experts comprised the statistic population of the study. a sample consisting of ...

1129 of the β-hairpin with the base of the A1 domain is unexpected and may account for the ability of VWD type 2B mutations to increase the binding affinity. The A1 domain contains a compact α/β fold delimited by a single disulfide loop. In the free A1 domain, the sequence extending on the amino-terminal side of the disul-fide bond lies against the α/β surface (8), and this amino-terminal exten...

BACKGROUND Ethiopia has been deploying specially trained new cadres of community based health workers in urban areas of the country known as urban health extension professionals since 2009. At present, relatively little work has focused on understanding to what extent this new program is accepted and used by the community. METHODS Both qualitative and quantitative surveys were performed from ...

In this study, adhesive wear extension in axisymmetric fretting contacts is simulated by applying the Contact Oxygenation Concept (COC) which illustrates influence of loadings on oxygen transport within interface. Di-oxygen flow modeled using an Advection-Dispersion-Reaction (ADR) approach was formerly proposed assuming third body as a porous medium crossed atmospheric gases. It shown that ADR ...

A rectangular dual of a graph G is contact representation by axis-aligned rectangles such that (i) no four share point and (ii) the union all rectangle. The partial extension problem for duals asks whether given can be extended to dual, is, there exists where some vertices are represented prescribed rectangles. simultaneous two (or more) graphs subgraph admit coincide on shared subgraph. Combin...

Spatial regions are a fundamental abstraction of geographic phenomena. While simple regions—disk-like and simply connected—prevail, in partitions complex configurations with holes and/or separations occur often as well. Swiss cantons are one highlighting example of these, bringing in addition variations of holes and separations with point contacts. This paper develops a formalism to construct t...
