The first WHO essential drugs list, published in 1977, was described as a peaceful revolution in international public health. The list helped to establish the principle that some medicines were more useful than others and that essential medicines were often inaccessible to many populations. Since then, the essential medicines list (EML) has increased in size; defining an essential medicine has ...

This paper presents a demonstration of an interactive 3D video on demand catalogue based on an innovative extension proposal to the X3D standard for 3D style sheets representation (X3DSS). This extension provides Web3D designers with a declarative way to build groundbreaking 3D graphical user interfaces (3DGUI) for Web3D. Thanks to new nodes allowing accessing a well-structured set of contents,...

Convergent extension of the mesoderm is the major driving force of vertebrate gastrulation. During this process, mesodermal cells move toward the future dorsal side of the embryo, then radically change behavior as they initiate extension of the body axis. How cells make this transition in behavior is unknown. We have identified the scaffolding protein and tumor suppressor Gravin as a key regula...

this study examines iranian agricultural researchers’ attitudes regarding collaboration with extension workers and the variables associated with the researchers’ attitudes. data were obtained using a questionnaire developed by agricultural research centers of charmahal and bakhtiari, isfahan, safiabad and khuzestan in 1998. the findings re-vealed that the researchers’ attitudes towards collabor...

Calcium is essential for many biological processes involved in cellular motility. However, the pathway by which calcium influences motility, in processes such as muscle contraction and neuronal growth, is often indirect and complex. We establish a simple and direct mechanochemical link that shows how calcium quantitatively regulates the dynamics of a primitive motile system, the actin-based acr...

The precise coordination of body parts is essential for survival and behavior of higher organisms. While progress has been made towards the identification of central mechanisms coordinating limb movement, only limited knowledge exists regarding the generation and execution of sequential motor action patterns at the level of individual motoneurons. Here we use Drosophila proboscis extension as a...

The study determined the willingness and capacity of poultry farmers to pay for extension services in Nasarawa State, Nigeria. At this research used a sample size of 120 poultry farmers. Simple descriptive statistics, Kuppuswamy scale and Logit regression model were used data analysis. The results showed that majority of the poultry farmers (87.5%) indicated their willingness to pay for extensi...

introduction: intra-thoracic goiter refers to the extension of enlarged thyroid tissue into the thoracic inlet. this condition can produce symptoms of compression on adjacent organs and can sometimes be accompanied by malignant transformation. therefore surgical treatment is almost always necessary. in order to remove the pathology with the fewest post-operative complications, selection of the ...

The purpose of the study was to examine compliance of extension personnel in Imo state agricultural extension service delivery system of Nigeria. A purposive and multi-stage random sampling was used to select 105 extension personnel from the three agricultural zones of the state. Data generated were analyzed using descriptive statistics such as frequencies and percentages, as well as mean score...
