The virtual private network (VPN) provides customers with predictable and secure network connections over a shared network infrastructure. The recently proposed hose model for VPNs has desirable properties in terms of greater flexibility and better multiplexing gain. However, the ‘classic’ fair bandwidth allocation scheme introduces the issue of low overall utilisation in this model; furthermor...

Ovarian cancer originates mainly from surface epithelial cells, which are potential targets of estrogen action. Using immunohistochemistry and RT-PCR analysis, aromatase (estrogen synthetase) can be detected in human ovarian surface epithelial tumors. In this study, we functionally characterized the aromatase expressed in a primary cell culture, normal human ovarian surface epithelial (HOSE) 17...

PURPOSE Epidemiological evidence implicates a heightened androgenic state in women with epithelial ovarian cancer. Androgen activity may be modulated by altered expression or activity of the androgen receptor (AR) or AR polymorphisms. Exon 1 of the AR gene contains a polymorphic (CAG)(n) sequence whose length is inversely correlated with transcriptional activity. EXPERIMENTAL DESIGN Different...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...

This paper reports an experimental study that determines the dissipative properties of a pressure fire hose, type «T», whose inner diameter is 77 mm, under static load conditions, taking into consideration structural elements hose in transverse direction. For this study, samples were separated from different sections hose. The involved both outer fabric reinforced frame and internal waterproofi...

A simple system for administration of continuous positive airway pressure breathing uses a corrugated hose in the modified Mapleson D system for anaesthesia. The only mechanical component of the system is a spring-loaded valve for positive end expiratory pressure.

BACKGROUND The highest incidence of listeriosis, due to consumption of ready-to-eat foods and fresh, shredded, minimally processed vegetables, occurs among pregnant women and the elderly. In order to reduce the prevalence of listeriosis among consumers, better protective measures are recommended. Chitosan films, with or without added essential oils, represent a modern, safe method of preserving...
