We describe a rare case of vertebra (intraosseous) hemangioma with bilateral and symmetrical epidural extension causing cord compression in a 24-year-old woman. The epidural component was isointense to cord on both T1 and T2 sequences, and enhanced markedly and homogenously following gadolinium administration. The gradual in onset and progressive nature with the typical enhancing pattern lead t...

We describe a process calculus featuring high level constructs for component-oriented programming in a distributed setting. We propose an extension of the higher-order π-calculus intended to capture several important mechanisms related to component-based programming, such as dynamic update, reconfiguration and code migration. In this paper, we are primarily concerned with the possibility to bui...

Component-based software development is gaining recognition as the key technology for the construction of high-quality, evolvable, large software systems in timely and affordable manners. Component search and service matching have become two of the key issues involved in this process. However, current proposals addressing these issues are based on the simplistic assumptions that components pres...

This study examined the training needs of agricultural extension agents in Delta State, Nigeria. A sample of 102 respondents was drawn from extension agents in the States’ Agricultural Development Programme (ADP), Ministry of Agriculture and Natural Resources (MANR) and the FADAMA Programme. Data were collected in February 2017 by using a structured and validated questionnaire. Data generated w...

The paper presents a cheap technique for the approximation of the harmonic extension from the boundary into the interior of a domain with respect to a given diierential operator. The new extension operator is based on the hierarchical splitting of the given f.e. space together with smoothing sweeps and an exact discrete harmonic extension on the lowest level and will be used as a component in a...

Critical reflection is integral to the action learning cycle (Kolb 1984) which underpins much present day extension theory. How often, however, do extension programs conduct an impact analysis to formally evaluate achievements against desired outcomes and so gain insights into the effectiveness of different extension strategies used? In 2008, two Integrated Pest Management (IPM) project teams w...

relationship between public and private sector is becoming an increasingly important issue in management of agricultural extension services. the need for a strong linkage could be identified as the gap between desirable and current situation. in this research, the differences among current and desirable situation in six diverse dimensions was calculated. the current and desirable situation was ...

the purpose of this study was to investigate the role of extension services in enhancing effectiveness of out growers’ credit system in kisumu county, kenya. the study specifically sought to determine whether public and private extension services play a significant role in enhancing effectiveness of out-growers’ credit system among smallholder sugarcane farmers. a total of 110 small scale farme...

abstractthe purpose of this study was to assess organizational and personnel structure in iranian agriculture extension system (iaes). the research instrument was a structural questionnaire including close-ended questions which its validity and reliability was confirmed by using expert panel and cranach’s alpha test, respectively. the statistical population of this research included all public ...
