Abstract:

This paper presents a review of node failure recovery algorithms in wireless sensor actor networks (WSANs). Due to wide area of innovation in wireless technology, WSANs have been the interesting area of application for last two or three decades in various fields. In WSANs, sensor node will explore the environment and transmit the gathered information to actor nodes. Actor node gathers or aggregates that information and performs specific operations in response to various events. Actors have to work together so it is essential to retain a strongly connected network topology at all the time. Sinc

AbstractA novel amphoteric polyacrylamide (PDAA) was prepared by inverse emulsion polymerization. The influence of its cationic degree and molecular weight on retention property was discussed. Then, the chemical structure and micromorphology of the obtained PDAA were characterized by Fourier infrared spectrum (FTIR), NMR hydrogen spectrum (1H NMR), gel permeation chromatography (GPC), and scanning electron microscope (SEM).

Abstract:

One polysaccharide deacetylase gene was cloned from Bacillus thuringiensis and designated pdaA. Disruption of pdaA did not affect vegetative growth and sporulation but obviously affected spore germination. When L-alanine was added into the spore suspension, the spores of the pdaA disruption mutant showed a slow and partial reduction in absorbance at OD600 and became phase pale gray compared with phase dark of the wild-type strain. In contrast with the outgrowing of wild-type spores after germination, the pdaA mutant spores were blocked at the stage of spore germination. Transmission electron m

Background: Pharmacists play an important role in managing patients with prescription drug abuse and addiction (PDAA). The objective of this study was to explore Alberta pharmacists’ practices, views and confidence in the management of patients at risk of or living with PDAA in their practice setting.

ABSTRACT The predicted amino acid sequence of Bacillus subtilis yfjS (renamed pdaA) exhibits high similarity to those of several polysaccharide deacetylases. β-Galactosidase fusion experiments and results of Northern hybridization with sporulation sigma mutants indicated that the pdaA gene is transcribed by EσG RNA polymerase. pdaA-deficient spores were bright by phase-contrast microscopy, and the spores were induced to germination on the addition of l-alanine.

Measurement of deacetylase activity showed that PdaA could deacetylate peptidoglycan treated with N-acetylmuramoyl-l-alanine amidase CwlH but could not deacetylate peptidoglycan treated with or without dl-endopeptidase LytF (CwlE).

These indicators are analogues of the purpurate components of murexide and tetramethylmurexide, in which two acetate groups have been incorporated into each molecule to render it membrane impermeant. The apparent dissociation constant for Ca is 0.95 mM for PDAA and 0.78 mM for DMPDAA.

A peptidoglycan structural modification found uniquely in spores is the formation of muramic δ-lactam. Production of muramic δ-lactam in Bacillus subtilis requires removal of a peptide side chain from the N-acetylmuramic acid residue by a cwlD-encoded muramoyl-l-Alanine amidase.

Abstract:

The species-area relationship (SAR) is a well-established, globally recognized ecological pattern, and research on SAR has expanded to include the phylogenetic diversity-area relationship (PDAR). However, this research has generally been limited to terrestrial systems. Using data on freshwater macroinvertebrates, the log–log form of the SAR and PDAR power models were compared between the Lhasa River and the Niyang River on the Tibetan Plateau in China. The study reveals that there is a significant difference in the slopes of SAR and PDAR between the two rivers, with the Lhasa River having a co

Abstract:

Pancreatico-duodenal artery aneurysm (PDAA) associated with stenosis or occlusion of the celiac trunk is a rare condition. Furthermore, PDAAs associated with stenosis of the superior mesenteric artery (SMA) are even more uncommon, with only six cases reported in the literature. We report a case of a 61-year old male patient who presented with hematemesis, haematochezia and haemorrhagic shock. The upper gastrointestinal endoscopy revealed an ulcerous lesion at the third portion of the duodenum, without achieving the haemostasis. The emergency laparotomy (suture of the lesion and gastro-entero-a

Abstract:

The photocurrent for poly(4-(dimethylamino)benzyl acrylate) (PDAA) photorefractive composites with (4-(diphenylamino)phenyl)methanol (TPAOH) photoconductive plasticizers was measured to be two orders of magnitude higher than that obtained with (2,4,6-trimethylphenyl)diphenylamine (TAA) photoconductive plasticizers. In this study, to determine the reason for the large difference in the photocurrent measured for PDAA photorefractive composites containing two different photoconductive plasticizers of TPAOH and TAA, the highest occupied molecular orbital (HOMO) level identical to the ionization po

Two reviewers independently selected studies published in peer-reviewed journals and extracted crude prevalence estimates and study characteristics.

Abstract:

En este artículo se presenta un modelo estocástico para analizar y simular lluvias horarias. El modelo que genera la ocurrencia de lluvias es un modelo periódico discreto autoregresivo de orden 1, denominado PDAR y aquél que genera las intensidades es uno estacionario autoregresivo (AR) de orden 1. Éste último requiere que las lluvias se transformen a una variable normal. La estimación de parámetros del modelo PDAR se hizo por el método de momentos mientras que para la estimación del modelo AR se utilizaron dos métodos: en el Método 1, las medias y desviaciones típicas horarias de la variable

Abstract:

Cut fibers (striation spacing, 3.6-4.2 microns) were mounted in a double Vaseline-gap chamber and studied at 14-15 degrees C. One or both of the Ca indicators fura-2 and purpurate-3,3' diacetic acid (PDAA) were introduced into the optical recording site by diffusion from the end pools. Sarcoplasmic reticulum (SR) Ca release was elicited by action potential stimulation. With resting [fura-2] = 0 mM at the optical site, the [Ca] transient measured with PDAA was used to estimate SR Ca release (Baylor, S.M., W.K. Chandler, and M.W. Marshall. 1983.

The value of the company represents a picture of the state of the company whether it is in good or bad condition. The value of the company can affect the views of investors in making decisions to invest. One way that can be used to see the good or bad value of a company is to assess the quality of the company's financial statements. The quality of financial reports in this study is seen from several aspects of earnings management, namely the Loss Avoidance Ratio (LAR), Profit Decline Avoidance Ratio (PDAR), and the Quality Audit Opinion Ratio (QAOR).

Existing literature suggests that analyses of landing time intervals employ simple statistical models based on time-separation histograms, usually approximated by normal distributions. Although the literature focuses on important issues such as safety, capacity improvements, and separation rules, it does not take into account another important issue: the possible, unique behavior of airlines, pilots, and controllers. In this study such possible, unique behavior is taken into account and a statistical analysis on landing time intervals is performed to find the operational properties of Los Ange

Abstract:

We investigate the factors that make it difficult to generalize pushdown automata for one-dimensional strings to two-dimensional arrays. Then we resolve the problems and construct two-dimensional pushdown array automata (PDAA). The relationship between isometric context-free array languages and pushdown array automata is established. Several examples of array automata are presented, and a pushdown array automaton is tested on VAX8650/VMS using PASCAL.
