BACKGROUND The morbidity of papillary thyroid microcarcinomas is increasing worldwide. Surgery is the main treatment for papillary thyroid microcarcinomas, and the choice of surgical method partly depends on the T stage of the tumor. However, according to the American Joint Commission on Cancer staging system (7th edition), the T stage of papillary thyroid microcarcinomas with different tumor e...

this research was based on primary data collected through well designed and pre-tested questionnaire, to determine awareness of farmers on extension methods used by adp in kano state of nigeria. multistage sampling technique was used, in which three local governments were randomly selected. secondly, three wards one each from the selected local governments (danbatta, gaya and madobi) were rando...

present study was conducted in the three provinces of pakistan with the objectives to study the curricula relevancy with the participatory extension, supervision and administration and its practical applicability at the field level. for this extension agents of the selected provinces were selected purposively. mail questionnaire were used as instruments for data collection form 227 respondents ...

this study examined the accuracy between extension professionals and farmers regarding their perceptions of privatization and commercialization of agricultural extension services. the study was carried out in delta state, nigeria and it had a sample size of 224 respondents comprising of 134 extension professionals of the delta state agricultural programme (dtadp) and 90 farmers that were random...

In [ECHLPT] and [S] it is shown that if the fundamental group of a Seifert fibred 3manifold is not virtually nilpotent then it has an automatic structure. In the unpublished 1992 preprint [G2] Gersten constructs a biautomatic structure on the fundamental group of any circle bundle over a hyperbolic surface. He asks if the same can be done for the above Seifert fibered 3-manifold. We show the ex...

Over the past two decades many countries have undertaken to decentralize government functions and transfer authority and responsibilities from central to intermediate and local governments, and often to communities and the private sector. Decentralization is potentially important to agricultural knowledge and information systems, but decentralization is not an end in itself, and successful dece...

We present an explicit construction for the central extension of the group Map(X, G) where X is a compact manifold and G is a Lie group. If X is a complex curve we obtain a simple construction of the extension by the Picard variety Pic(X). The construction is easily adapted to the extension of Aut(E), the gauge group of automorphisms of a nontrivial vector bundle E.

Central grid extension is the predominant policy taken by governments in developing countries towards increasing access to electricity. While the levels of consumption afforded by access to the central grid have the potential to greatly enhance human development, actual consumption is subject to the reliability of the central grid. Further, due to the institutional complexities of extending the...
