Follow up study to assess the use and performance of household water filters in Zambia

Effective household water treatment has the potential to improve drinking water quality and prevent diarrhoeal disease if used correctly and consistently over time. We previously conducted a randomized, controlled trial of water filters among households in Zambia with children under two years of HIVpositive mothers. One year after completion of the trial, we conducted a follow up study to assess use and performance the household filters. Ninety percent of participating households met the criteria for current users, and 75% had stored water with lower levels of faecal contamination than source water. Although this study provides some encouraging evidence about the potential to maintain HWTS use and performance, further research is necessary to assess whether these results can be achieved over longer periods and with larger populations.
Development and Validation of the German Work-Related Curiosity Scale

Curiosity, a personality trait underlying behavioral tendencies related to knowledge acquisition, learning, and thinking, can be expected to be of high relevance in the world of work. There is, however, to date no work-related curiosity measure. The present article reports results regarding the development and validation of the new 10-item Work-Related Curiosity Scale. Based on two studies, the measure had a one-factor solution, acceptable internal consistency, and expected construct validity. In Study 2, incremental criterion-re- lated validities were found over and above five general curiosity scales (ΔR 2 between .12 and .15), which is in line with the frame-of- reference approach underlying the development of the scale. Interestingly, the lack of evidence for criterion-related validity in Study 1 indicates that these results do not generalize across positions.
User Experience with Security Elements in Internet and Mobile Banking

Abstract Background/Purpose: Maintaining a balance between security and a positive user experience in mobile and Internet banking is becoming increasingly difficult for the providers of banking services. The goal of our research is to analyse user opinions about the current situation: how users perceive security and how the authentication methods they are using affect user experience. Methodology: Data were collected using an online survey among the users of 15 banks operating in Slovenia, and statistical methods were applied to analyse them. Results of the users’ study were evaluated and commented by a limited number of interviewed banking security experts. Results: The results indicate that the use of mobile banking in Slovenia is relatively low, as only 30 percent of respondents use mobile banking along with Internet banking. Slovenian users perceive security to be the most important factor in mobile and online banking, closely followed by reliability. We also verified whether the users knew which authentication methods they were using: 69% of respondents selected the correct authentication method. The opinion of 88% of respondents was that authentication methods do not limit them when using mobile and Internet banking. Results of the study of user’s opinions did not surprise the experts, although experts’ views about the balance between security and usability diverged considerably. Conclusion: Our results indicate that, in Slovenia, users of the Internet and mobile banking services regard security to be the most important element in mobile or Internet banking and find user experience less important while they absolutely do want products that are easy to use.
A Review on Molecular Mechanisms of Reocclusion Following Thrombolytic Therapy in Ischemic Stroke Patients

Stroke is the second most common cause of death worldwide. Despite many advances in the field of vascular neurology, intravenous (IV) tissue plasminogen activator (tPA) remains the only approved treatment for acute ischemic stroke, even though complication risk such as hypofibrinolysis and reocclusion, are reported in as high as 25-34% of cases. The exact mechanisms of unsuccessful thrombolytic therapy are unclear. Some molecular events such as activation of intrinsic and extrinsic pathways C - reactive protein (CRP), thrombin-activatable fibrinolysis inhibitor (TAFI), plasminogen activator inhibitor-1 (PAI-1) are the main causes of failure. Moreover, release of thrombin after tPA therapy, tissue factor pathway inhibitor (TFPI) inhibition, and some of gene polymorphisms may play a crucial role in reocclusion. Due to the necessity for development of effective strategies to improve clinical efficacy of tPA therapy, we aimed to evaluate the possible mechanisms, which may be responsible for re-occlusive complications after tPA therapy.
Impact Factors Influencing the Nitrate Accumulation of Leafy Vegetables in Plant Factory

In recent years, cultivation of leafy vegetables such as lettuce and spinach using hydroponic systems in closed plant factories under light-emitting diodes (LEDs) lamps is becoming popular. Unfortunately, these vegetables may accumulate high level of nitrate which pose serious human health implications, upon being consumed by consumers. Finding solutions to lower the nitrate content through environmental control is important for vegetable quality control. Therefore, strategies are leaning towards to minimize the nitrate accumulation in leafy vegetables for agricultural product security. The aim of this review is to understand the factors leading to nitrate accumulation in a closed plant factory, to study the factors affecting nutrient ions management in hydroponic system, to review the cultural measures that may lead to minimize the nitrate content in leafy vegetables under controlled environment. Genetic, agronomic (e.g. supply, composition, timing, and form of nitrogen fertilizer), and environmental factors (e.g. temperature, light quality, intensity and photoperiod, carbon dioxide concentration) can significantly impact the nitrate level in leafy vegetables. To produce high quality vegetables especially in low nitrate content, regulatory methods during cultivation including light quality and other aspect of nutrient solution, can Improve the value-added product.
Image-Based Framework for Concrete Surface Crack Monitoring and Quantification

In the engineering community, nondestructive imaging has been widely used for damage identification by capturing anomalies on the surface or inside of structural elements. In this paper, we focus on one of the most common damage types observed in civil engineering, namely, concrete surface cracks. To identify this type of damage, we propose an image-based framework, whereby optical cameras provide the source images. The framework involves several advanced image processing methods, including: (i) the determination of damage occurrence using time-series images, (ii) the localization of damage at each image frame, and (iii) the geometric quantification of damage. Challenges that may arise when images are obtained in the laboratory or field environment are addressed. Two application examples are provided to demonstrate the use and effectiveness of the proposed approach.
Representation theorems for connected compact Hausdorff spaces

We present two theorems which can be used to represent compact connected Hausdorfi spaces in an algebraic context, using a Stone-like representation. The flrst theorem stems from the work of Wallman and shows that every distributive disjunctive normal lattice is the lattice of closed sets in a unique up to homeomorphism connected compact Hausdorfi space. The second theorem stems from the work of Jung and Sunderhauf. Introducing the notion of strong proximity involution lattices, it shows that every such lattice can be uniquely rep- resented as the lattice of pairs of compact and open sets of connected compact Hausdorfi space. As a consequence we easily obtain a some- what surprising theorem birepresenting distributive disjunctive normal lattices and strong proximity involution lattices.
BEHIND THE SUBJECTIVE VALUE OF TRAVEL TIME SAVINGS: THE PERCEPTION OF WORK, LEISURE AND TRAVEL.

In this paper the authors use a small population of travelers in Santiago, Chile to show that coupling microeconomically-founded activity models and travel choice models can yield a better understanding of individual travel behavior, especially through the analysis of the value of time. Many travel choice models have been used to calculate the full value of travel time savings, but its components have never been estimated quantitatively. The data reveal perceptions of work time, leisure, and travel time that hide behind formation of a willingness to pay to reduce travel, according to the authors. The paper also suggests future areas for research.
A comparative study of the perceptions of professional staff on their contribution to student outcomes

This study examined the perceptions of professional staff on their contribution to student outcomes. An online Delphi survey method was used to collect data from two expert panels: professional staff based in faculties and professional staff based in central university departments. The aim of this method is for the panels to reach consensus. The expert panels were asked to rank 10 propositions which support successful student outcomes. After three rounds the faculty-based panel had reached only a ‘very weak’ consensus, and the non-faculty-based panel only a ‘weak’ consensus. The highest-ranked proposition for both panels related to the ways in which institutions behave towards students: being welcoming and ensuring efficiency. Propositions relating to organisational culture were ranked relatively low indicating that professional staff may underestimate their contribution to these propositions.
Effects of enzyme levels in total mixed ration containing oil palm frond silage on intake, rumen fermentation, and growth performance of male goat

This experiment was conducted to study the effects of supplementing the total mixed ration (TMR) containing oil palm frond (OPF) silage with different levels of enzyme on feed intake and growth performance of goat. Twenty four post-weaning Boer  Thai Native crossbred male goats with initial body weight (BW) of 11-18 kg, were arranged to receive four dietary treatments in a randomized complete block design. The diet used in the study contained 60% oil palm frond silage and 40% concentrate. The enzyme mixture produced by Aspergillus spp. BCC 274, containing approximately 110 7 , 910 6 , 210 6 , 110 6 and 210 6 unit/kg dry weight for xylanase, -glucanase, cellulase, mannanase and amylase, respectively, was supplemented to the concentrate portion at 0, 2, 4 and 6 g/kgDM of the TMR. The results showed that the supplementation of enzyme to the TMR did not affect (P>0.05) dry matter intake (DMI). Goats receiving TMR supplemented with enzyme at 2 g/kgDM tended to have higher ADG and better feed per gain ratio as compared with other treatments. Coefficient of DM digestibility of TMR was not significantly affected by the enzyme supplementation. In addition, there were no significant differences (P>0.05) among treatments regarding, average NH 3 -N concentration, the amount of C 2 , C 3 and C 4 in the rumen fluid and BUN concentration. However, overall mean of ruminal NH 3 -N concentration was significantly lower in goat receiving TMR supplemented with enzyme at 2 g/kgDM than that of goat receiving TMR with no enzyme supplementation (P<0.05). Based on this experiment, the application of enzyme at 2 g/kgDM in TMR containing OPF silage could increase ruminal availability of slowly digestible carbohydrate and improve goat performance.
An Independent and External Validation of the ACC NCDR Bleeding Risk Score among a National Multi-Site Community Hospital Registry of Cardiac Interventions

Background : An accurate tool with good discrimination for bleeding would be useful to clinicians for improved management of all their patients. Bleeding risk models have been published but not externally validated in independent clinical dataset. We chose the NCDR PCI score to validate within a large, multi-site community datasets. The aim of the study was to determine the diagnostic utility of this bleeding risk score tool. Methods : This is a large-scale retrospective analysis utilizing American College of Cardiology data from a 37-hospital health system. The central repository of PCI procedures between 6-1-2009 and 6-30-2012 was utilized to validate the NCDR PCI bleeding risk score (BRS) among 4693 patients. The primary endpoint was major bleeding. Discriminant analysis calculating the receiver operating characteristic curve was performed. Results : There were 143 (3.0%) major bleeds. Mean bleeding risk score was 14.7 (range 3 – 42). Incidence of bleeding by risk category: low (0.5%), intermediate (1.7%), and high risk (7.6%). Patients given heparin had 113 (3.7%) major bleeds and those given bivalirudin had 30 (2.1%) major bleeds. Tool accuracy was poor to fair (AUC 0.78 heparin, 0.65 bivalirudin). Overall accuracy was 0.71 (CI: 0.66-0.76). Accuracy did not improve when confined to just the intermediate risk group (AUC 0.58; CI: 0.55-0.67). Conclusion : Bleeding risk tools have low predictive value. Adjustment for anticoagulation use resulted in poor discrimination because bivalirudin differentially biases outcomes toward no bleeding. The current state of bleeding risk tools provides little support for diagnostic utility in regards to major bleeding and therefore have limited clinical applicability.
Magnetization Dynamics in Arrays of Quantum Dots

The possibility of preparing materials based on quantum dots with fine-tuned magnetic properties has opened up the door for designing new and more efficient devices where the interplay of different microscopic phenomena balances out in useful ways. Nevertheless, our knowledge of the precise interaction of complex objects built from a great number of such nanometric magnetic components is still limited. The investigation of the spin or magnetization dynamics in such materials represents an important opportunity to better comprehend and predict some missing pieces for the advancement of a great deal of promising technologies.
Deep infrared imaging of close companions to austral A- and F-type stars

The search for substellar companions around stars with different masses along the main sequence is critical to understanding the different processes leading to the formation of low-mass stars, brown dwarfs, and planets. In particular, the existence of a large population of low-mass stars and brown dwarfs physically bound to early-type main-sequence stars could imply that the massive planets recently imaged at wide separations (10-100 AU) around A-type stars are disc-born objects in the low-mass tail of the binary distribution and are thus formed via gravitational instability rather than by core accretion. Our aim is to characterize the environment of early-type main-sequence stars by detecting substellar companions between 10 and 500 AU. The sample stars are also surveyed with radial velocimetry, providing a way to determine the impact of the imaged companions on planets at ≲10 AU. High-contrast and high angular resolution near-infrared images of a sample of 38 southern A- and F-type stars were obtained between 2005 and 2009 with the instruments NaCo on the Very Large Telescope and PUEO on the Canada-France-Hawaii Telescope. Direct and saturated imaging were used in the J to K s bands to probe the faint circumstellar environments with contrasts of ~5 × 10 -2 to 10 -4 at separations of 0". 2 and 1", respectively. Using coronagraphic imaging, we achieved contrasts between 10 -5 and 10- 6 at separations >5". Multi-epoch observations were performed to distinguish comoving companions from background contaminants. This survey is sensitive to companions of A and F stars in the brown dwarf to low-mass star mass regime. About 41 companion candidates were imaged around 23 stars. Follow-up observations for 83% of these stars allowed us to identify a large number of background contaminants. We report detection of 7 low-mass stars with masses between 0.1 and 0.8 Mo in 6 multiple systems: the discovery of an M2 companion around the A5V star HD 14943 and detection of HD 41742B around the F4V star HD 41742 in a quadruple system. We resolve the known companion of the F6.5V star HD 49095 as a short-period binary system composed of 2 M/L dwarfs. We also resolve the companions to the astrometric binaries i Crt (F6.5V) and 26 Oph (F3V), and identify an M3/M4 companion to the F4V star o Gru, associated with an X-ray source. The global multiplicity fraction measured in our sample of A and F stars is >16%. This has a probable impact on the radial velocity measurements performed on the sample stars.
The person-centred approach to an ageing society

Modern care is often based on investigations such as laboratory markers and imaging - for example, x-ray or ultrasound. The results contribute to a diagnosis and, if judged necessary, treatment is initiated. This diseased-oriented approach is the prevailing mode of management in modern medicine. In contrast, person-centered care (PCC) takes the point of departure from each person´s subjective experience of illness and its impact on daily life. A patient is considered as a person with emotions and feelings. PCC is considered present within clinical care according to a definition articulated by the Centre for Person Centred Care at the University of Gothenburg (GPCC) when three core components are present: elicitation of a detailed patient narrative; formulated partnership between caregiver and patient and documentation of the partnership in the patient record. Accordingly, when there is an illness requiring care and the person is attended using these components, PCC is being applied. In most situations today, PCC is not applied as the narrative is not fully elicited or the partnership and/or the documentation are not included. It is proposed that the challenge to Society arising from changing demographics can be addressed by implementing PCC and creating an alternative to existing healthcare. The importance and benefits of such an approach on a wider scale is not yet clear as research has been limited to date. Studies in selected patient populations (heart failure and hip fractures), however, have shown promising results. As the population ages, there will be a dramatic increase in healthcare consumption. Even with technological developments, there will be a need for tremendous resources to be dedicated to care. A new organization and attitude from healthcare policymakers and providers above and beyond the present model appears required in order to respond to this demand. As part of such change, person-centred care, with the interaction between healthcare providers and the person of the patient, can facilitate, compensate and develop more effective healthcare services for the future.
Alteration of blood glucose and hemoglobin levels in zebrafish exposed to sumithion

Sumithion is extensively used in the agricultural land to control brittle and larval rearing aquaculture ponds to control tiger bug. The present study was conducted to evaluate the effects of sumithion on blood glucose and hemoglobin levels in zebrafish, Danio rerio . At first acute toxicity (96 h LC50 value 7.89 mg/L) of sumithion was determined for sexually matured zebrafish. Then the fish were exposed to four concentrations (0, 0.5, 1.0 and 2.0 mg/L) of sumithion for a period of 7 days. The sexual dimorphic changes in blood glucose levels were observed in the present study. In male, the blood glucose levels were significantly (P<0.05) increased in all concentrations (0.5, 1.0 and 2.0 mg/L) of sumithion compared to control (0 mg/L), while in female the blood glucose levels were significantly (P<0.05) increased only in high concentration (2.0 mg/L). Interestingly, the blood glucose level was higher in females than the males of zebrafish. The recorded hemoglobin values were significantly decreased with the increasing concentration of sumithion in both male and female. The present investigation revealed the toxic potentiality of sumithion on the zebrafish. Progressive Agriculture 27 (2): 216-221, 2016
Distortionary Taxation for Efficient Redistribution

This article uses a simple model to review the economic theory of efficient redistributive taxation. The model economy is a Lucas-tree economy, in which income comes from a stock of productive capital. Agents, who own the capital stock, are heterogenous with respect to their preference for early versus late consumption. A competitive capital market, in equilibrium, supports a unique Pareto-efficient allocation of consumption among the agents, i.e., the First Welfare Theorem holds. The equilibrium allocation represents one efficient division of the total gains from trade that are available in the economy. All other efficient divisions of the gains from trade, represented by a continuum of other Pareto-efficient allocations, are inconsistent with competitive capital market equilibrium. If agents' preference types are public information, nondistortionary wealth transfers are sufficient to implement any Pareto optimum as a market equilibrium, i.e., the classic Second Welfare Theorem holds. If agents' preferences are private information, however, the classic Second Welfare Theorem fails. A class of distortionary tax systems is characterized under which a modified Second Welfare Theorem holds: Every constrained-Pareto-optimal allocation can be supported as an equilibrium subject to distortionary taxes.
MINIATURE FOLDED PRINTED QUADRIFILAR HELICAL ANTENNA WITH INTEGRATED COMPACT FEEDING NETWORK

A miniature folded printed quadrifllar helical antenna (FPQHA) using a novel compact feeding network is proposed. Folding and meandering techniques are used to obtain 66% of size reduction for the axial length of the printed quadrifllar helical antenna. A compact feeding network using an out-of-phase power divider based on double-sided parallel-strip lines and a Wilkinson power divider is designed. A fabricated prototype of the FPQHA employing the compact feeding network is presented. The measured positive gain bandwidth is from 380MHz to 425MHz with a re∞ection coe-cient less than i20dB and an axial ratio below 2dB. The measured maximum gain is 3.08dBic at 395MHz with a half-power beamwidth of 150 - . With good radiation performance and integrated feeding network, the proposed antenna can become a better candidate in satellite and mobile communications.
