The purpose of this study was to determine computer and Internet use in agricultural extension by Extension Workers (EWs). This study used a descriptive-correlational design.Population for the study consisted of all extension workers (N= 320) in Isfahan Province, Iran. A stratified sampling technique and census was used to select EWs (n = 200). Overall, findings indicate that EWs have access to...

The study investigated the effect of Community-Based Paid Extension (CPE) on vulnerability reduction of smallholder dairy farmers. Randomly sampled 255 farmers were interviewed together with 15 key informants’ interview. Both statistical analysis and thematic approach were employed to achieve triangulation. In about 68 % of cases, CPE reduced vulnerability to a degree experienced as ‘moderate’,...

the resonant frequency and sensitivity of an atomic force microscope (afm) cantilever with assembled cantilever probe (acp) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. the proposed acp comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the afm capable of topography at sidew...

this study compared farmers’ rating of extension effectiveness in technology dissemination to the level of adoption. in conducting the study, 180 farmers participating in extension programme in cross-river state were randomly selected through multi-stage random sampling technique. the data collected through a structured questionnaire were analyzed using the t-test of significance of difference ...

a subgroup h of a group g is called inert if‎, ‎for each $gin g$‎, ‎the index of $hcap h^g$ in $h$ is finite‎. ‎we give a classification ‎of soluble-by-finite groups $g$ in which subnormal subgroups are inert in the cases where $g$ has no nontrivial torsion normal subgroups or $g$‎ ‎is finitely generated‎.

Climate change represents the major challenge to Sudan agricultural production, economics and food security. Changes in temperature, rainfalls, water availability, increased outbreak of pest and diseases, land degradation, soil erosion, shrinking of grazing and cultivate areas, ongoing desertification and the other aspects of climate change have direct significant impact on agricultural product...

The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures of the rock mass and also from the extension of the newly formed cracks within the intact ...

A cross-sectional study was undertaken to examine the aquaculture extension service in Kenya.  Primary data collected using a semi-structured questionnaire administered 292 randomly selected fish farmers and 56 officers different counties Kenya. Descriptive statistics mainly mean frequencies were computed determine key characteristics of officers. Inferential done Chi-Square test goodness ...

Reluctance towards implementation of precision agriculture (PA) seems to be based on lackof consideration to education, extension, and research sectors. The objective of this study isto identify educational, extensional, and research requirements in application of the PAsystem. The research population included all the experts in Qazvin province who are familiarwith PA concepts and PA’s equipmen...

This paper puts forward a real-time angular tracking (motion capture) system for a low cost upper limb exosuit based on sensor fusion; which is integrated by an elastic sleeve-mitten, two inertial measurement units (IMU), two flex sensors and a wireless communication system. The device can accurately detect the angular position of the shoulder (flexion-extension, abduction-adduction and interna...
