Esophageal pressure (P(Es)) can be used to approximate pleural pressure (P(pl)) and might be clinically useful, particularly in the obese e.g., to guide mechanical ventilator settings in critical illness. However, mediastinal artifact (the difference between true P(pl) and P(Es)) may limit acceptance of the measurement, and reproducibility of P(Es) measurements remains unknown. Therefore, we ai...

The Transmission Control Protocol (TCP) is used for reliable delivery of data over unreliable networks. Practically, most TCP mechanisms have been carefully designed for wired networks. Neglecting the characteristics of wireless environments can lead to TCP implementations with poor performance. In order to use TCP in mobile networks, improvements have been proposed in this paper to enhance TCP...

This paper presents a new implementation of a hybrid ciphering system of images in Fourier domain based on two chaotic maps. The first map is the Bakermap,which is used to scramble the image pixels in three modes of operation (CBC, CFB and OFB). The second map is the logistic map,whose secret key depends on the plain text. In the key generation step of the logistic map, the chaotic stream is ge...

BACKGROUND Esophageal stricture (ES) and gastric outlet obstruction (GOO) can occurred in patients injured by the ingestion of corrosive agents. These complications may occur concurrently but has not been reported in the literature. The aims of this study are to assess the effects and complications of endoscopic-guided balloon dilations (EBD) in patients with corrosive-induced upper gastrointes...

an experiment was conducted to evaluate the extracted (es) and mechanical (ms) soybean meals two levels 25% and 35% in broiler chicken feeding. three hundred and fifty two one-day-old unsexed lohman chickens were placed in four treatments by 4 replicates and 22 chickens in each in a 2×2 factorial arrangement. feed intake was increased significantly in starter period by es in comparison with ms....

Purpose: Electrotherapy is a common intervention for the rehabilitation of Bell’s palsy. Low-level laser therapy (LLLT) and electrical stimulation (ES) are two therapeutic interventions for Bell’s palsy that have been proven to be superior to conventional treatments. To date, no clinical trial has compared the effectiveness of these two interventions. This pilot study aims to compare the effect...

In the wound healing research, the exact mechanism of action of different modalities of electrical stimulation (ES) remains controversial and unresolved. In this study we discuss a particular ES, with a different type of waveform, corresponding to the principle of stochastic resonance. Between July 2008 and May 2010, 32 patients were enrolled and ES was applied to wounds using the bioelectrical...
