Water service delivery to most residents of peri-urban areas of greater Maputo depends largely on alternative service providers. mostly in the form of small-scale independent providers (SSIPs). This paper discusses the present and long-term challenges facing SSIPs in supplying quality water of sufficient quantity in peri-Urban Maputo and possible human health risks associated with the consumption

One important issue in the study of individual differences in cognitive abilities has been the question whether abilities tend to become more differentiated with increasing age. The present study examines age-related differentiation in the structure of cognitive abilities among children 3 × 2013; 7 years of age, using data from the recently undertaken Swedish standardisation of the Wechsler Presch

In vitro, pancreatic triglyceride lipase requires colipase to restore activity in the presence of inhibitors, like bile acids. Presumably, colipase performs the same function in vivo, but little data supports that notion. Other studies suggest that colipase or its proform, procolipase, may have additional functions in appetite regulation or in fat digestion during the newborn period when pancreati

PURPOSE: To assess how patients perceive health-related quality of life (HRQOL) after endovascular and open abdominal aortic aneurysm (AAA) repair. METHODS: Forty-two consecutive patients (33 men; mean age 74 years, range 46-81) were assessed prospectively before and after elective endovascular (n = 21) and open (n = 21) AAA repair. Aneurysm morphology dictated the type of repair. The two patient

BACKGROUND: Halothane and isoflurane have been shown to induce disparate effects on different brain structures in animals. In humans, various methods for measuring cerebral blood flow (CBF) have produced results compatible with a redistribution of CBF toward deep brain structures during isoflurane anesthesia in humans. This study was undertaken to examine the effects of halothane and isoflurance o

High-resolution (K3p sigma and pi)->sigma absorption spectrum of KF in the photon energy range of 18.2-19.4 eV was measured at the new FINEST beamline branch on the I3 beamline on MAX III. The experimental spectrum is presented and interpreted using nonrelativistic ab initio molecular calculations corrected with perturbation theory treatment to account for spin-orbit interaction. Resonant Auger de

Simple light use efficiency (epsilon) models of net primary production (NPP) have recently been given great attention (NPP = epsilon x absorbed photosynthetically active radiation). The underlying relationships have, however, not been much studied on a time step less than a month. In this study daily NPP was estimated as the sum of net ecosystem exchange (NEE) and heterotrophic respiration (R-h) o

Four enrichment PCR protocols for detecting unlysed cells of pathogenic Yersinia enterocolitica were studied. First, the probability of detecting Y. enterocolitica cells of known concentrations by a multiplex PCR assay was determined, and it was found to follow a logistic regression model. From this model, the probability of detecting Y enterocolitica at a specific concentration could be estimated

BACKGROUND: Cancer of the pancreas is a common disease, but the large majority of patients have tumours that are irresectable at the time of diagnosis. Moreover, patients whose tumours are clearly beyond surgical cure are best treated non-operatively, if possible, by relief of biliary obstruction and percutaneous biopsy to confirm the diagnosis and then consideration of oncological treatment, nota

Twenty-four individuals, who were 16 years of age or younger when they sustained a fracture of the radial head or neck, were examined at a mean of 19 years (range 14-25 years) after injury. The 12 girls and 12 boys were a mean age of 11 years (range 5-16 years) when the fracture was sustained. Two were excluded due to late resection of the radial head following persisting pain. The fractures, whic

Serial MRI including diffusion and perfusion imaging was performed in a patient with hypertensive encephalopathy. At admission, the patient was disorientated and presented with seizures and cortical blindness. Perfusion imaging showed a marked reduction in blood volume and flow, with corresponding vasogenic oedema in the occipital, posterior temporal, and, to a lesser extent, frontal lobes. The cl

Analogues of the irreversible protease inhibitors TPCK and TLCK have been synthesized and tested as inhibitors of the bacterial cysteine protease IdeS excreted by Streptococcus pyogenes. Eight compounds were identified as inhibitors of IdeS in an in vitro assay. The most potent compounds contained an aldehyde function, thus acting as efficient reversible inhibitors, nitrile and azide derivatives s

This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual-Pair condition) where individual effort preceded pair collaboration showed better calibration compared w

Dawkins in his The Selfish Gene(1) quite aptly applies the term "selfish" to parasitic repetitive DNA sequences endemic to eukaryotic genomes, especially vertebrates. Doolittle and Sapienza (2) as well as Orgel and Crick (3) enlivened this notion of selfish DNA with the identification of such repetitive sequences as remnants of mobile elements such as transposons. In addition, Orgel and Crick (3)

Objectives: To describe subjective quality of life and health, self-perceived instrumental activities of daily living (I-ADL) ability and adaptation strategies, and to explore possible relationships between these variables in fibromyalgia patients. Design: Two instruments were used with fibromyalgia patients: the Fibrositis Impact Questionnaire and 'Living with fibromyalgia - adaptation to chronic

The halotolerance of a cold adapted alpha-amylase from the psychrophilic bacterium Pseudoalteromonas haloplanktis (AHA) was investigated. AHA exhibited hydrolytic activity over a broad range of NaCl concentrations (0.01-4.5 M). AHA showed 28% increased activity in 0.5-2.0 M NaCl compared to that in 0.01 M NaCl. In contrast, the corresponding mesophilic (Bacillus amyloliquefaciens) and thermostable

Two hundred one consecutive, primary, noninfected Charnley (Thackray, Leeds) hip arthroplasties, implanted from 1968 to 1985 due to adult-onset rheumatoid arthritis, were matched in pairs with respect to year of operation, age, and sex with 201 Charnley prostheses implanted due to osteoarthritis. The 10-year survival estimate for nonrevisions was 95% in the rheumatoid group and 89% in the osteoart

After a long period of focus on western and East Asian scripts there is now a general trend in the on-line handwriting recognition community to explore recognition of other scripts such as Arabic and various Indic scripts. One difficulty with the Arabic script is the number and position of diacritic marks associated to Arabic characters. This paper explores the application of a template matching s
