Opportunistic Routing (OR) is an effective and enhanced routing scheme for wireless multihop environment. OR is an approach that selects a certain number of best forwarders (candidates) at each hop by taking the advantage of the broadcast nature of the wireless medium to reach the destination. When a set of candidates receive the packet, they coordinate with each other to figure out which one h...

The Content Delivery Networks (CDNs) federation, also named Content Distribution Internetwork (CDI) has been proposed by the CDI IETF Working Group, but currently there are not running examples. In this position paper we analyses the issues concerning this new research area and propose a possible architecture for a CDI.

MANAGEMENT of labor after previous cesarean delivery continues to be a controversial area of obstetric practice. Neither repeat cesarean delivery nor a trial of labor are without risk. Currently, cesarean delivery is the most commonly performed operation, and repeat cesarean delivery is the most common indication. Although the prevalence of vaginal birth after cesarean delivery (VBAC) increased...

background : endometrial cancer is the most common type of malignancy in female reproductive system and is the fourth common cancer after breast, lungs and colorectal cancers. our aim is to report epidemiology and frequency types of endometrial cancer and clinical staging and grading of this disease. methods : in this description and cross-sectional study, 75 patients with diagnosed endometrial...

A new method for the intramolecular glycosylation of alcohols is described. Utilizing carbohydrate-derived silanes, the catalytic dehydrogenative silylation of alcohols is followed by intramolecular glycosylation. Appropriate combinations of silane position and protecting groups allow highly selective access to bmanno, a-gluco, or b-gluco stereochemical relationships as well as 2-azido-2-deoxy-...

BACKGROUND Our aim was to estimate the prevalence of stress urinary incontinence 4 years after the first delivery and analyze its risk factors. METHODS A retrospective cohort survey was conducted in a French university hospital. The 669 primiparous women who delivered in our department in 1996 a singleton in a vertex position between 37 and 41 weeks of amenorrhea were included. A mailed quest...

BACKGROUND The objective was to quantify hydrostatic effects on continuous subcutaneous insulin infusion (CSII) pumps during basal and bolus insulin delivery. METHODS We tested CSII pumps from Medtronic Diabetes (MiniMed 512 and 515), Smiths Medical (Deltec Cozmo 1700), and Insulet (OmniPod) using insulin aspart (Novolog, Novo Nordisk). Pumps were filled and primed per manufacturer's instruct...

BACKGROUND Intranasal olfactory drug delivery provides a non-invasive method that bypasses the Blood-Brain-Barrier and directly delivers medication to the brain and spinal cord. However, a device designed specifically for olfactory delivery has not yet been found. METHODS In this study, a new delivery method was proposed that utilized electrophoretic forces to guide drug particles to the olfa...

The most important challenge at the forefront of the national agenda is the need for health care reform. Major concerns of the current system are cost and access to care. This article discusses numerous congressional proposals and strategies for addressing these concerns. ET nurses are in a unique position to influence health care delivery. The Wound Ostomy and Continence Nurses Society has imp...

A new method for the intramolecular glycosylation of alcohols is described. Utilizing carbohydrate-derived silanes, the catalytic dehydrogenative silylation of alcohols is followed by intramolecular glycosylation. Appropriate combinations of silane position and protecting groups allow highly selective access to β-manno, α-gluco, or β-gluco stereochemical relationships as well as 2-azido-2-deoxy...
