The purpose of the current study was to identify the biomechanical features of elite female baseball pitching. Kinematics and kinetics of eleven elite female baseball pitchers were reported and compared with eleven elite male pitchers. Results suggested that females share many similarities with males in pitching kinematics, with a few significant differences. Specifically, at the instant of str...

This paper examines the structures of information transfer to the agricultural (production) and agro-alimentary (transformation and commercialization of the products) sector within Spain. A historical perspective is provided to better illustrate the reality and complexity of Spain with regard to the systems of agrarian extension, agricultural research, resources provided by Spain’s central admi...

ABSTRACTThis study examined information flow on minisett technology among yam farmers in Delta State, Nigeria. A sample size of 180 respondents was involved in the study. Data were obtained from respondents of the study through the use of a validated interview schedule. Percentage, frequency count and mean scores were used to summarize data, while line diagrams were used to develop maps of info...

Tunneling nanotubes are important membrane channels for cell-to-cell communication. In this study, we investigated the effect of the microenvironment on nanotubular structures by preparing a three-dimensional silk fibroin micropillar structure. In previous reports, tunneling nanotubes were described as stretched membrane channels between interconnected cells at their nearest distance. They hove...

We prove the existence of contact submanifolds realizing the Poincaré dual of the top Chern class of a complex vector bundle over a closed contact manifold. This result is analogue in the contact category to Donaldson’s construction of symplectic submanifolds. The main tool in the construction is to show the existence of sequences of sections which are asymptotically holomorphic in an appropiat...

BACKGROUND Basal cell carcinoma (BCC) is the most common malignancy with increasing incidence worldwide. The tumor invades surrounding tissues in an irregular pattern via subclinical and microscopic finger-like growths known as subclinical extension. Subclinical extension may be responsible for incomplete resection of the tumor. This study investigates the subclinical extension of BCC. METHOD...

Because the constant extension ensemble of single chain molecule is not always equivalent with constant force ensemble, a model of double-stranded conformations, as in RNA molecules and βsheets in proteins, with fixed extension constraint is built in this paper. Based on polymer-graph theory and the self-avoiding walks, sequence dependence and excluded-volume interactions are explicitly taken i...

BACKGROUND Pedicle-screw-based posterior dynamic stabilization devices are designed to alleviate the rate of accelerated degeneration of the vertebral level adjacent to the level of spinal fusion. A new pedicle-screw-based posterior dynamic stabilization device- the Awesome Dynamic Rod System was designed with curve cuts on the rods to provide flexibility. The current study was conducted to eva...

The process of collection development, collection generating and obtaining information is of basic debates in libraries and information centers which a lot of articles have been written about the methods of collection development of information as well as the application of information technology, accordingly, to this day. This article, as opposed to other articles, which are about the prevaili...
