Simultaneous Wireless Information and Power Transfer Mechanism in Interference Alignment Relay Networks

This paper considers a simultaneous wireless information and power transfer (SWIPT) mechanism in an interference alignment (IA) relay system, in which source nodes send wireless information and energy simultaneously to relay nodes, and relay nodes forward the received signal to destination nodes powered by harvested energy. To manage interference and utilize interference as energy source, two-SWIPT receiver is designed, namely, power splitting (PS), and antennas switching (AS) has been considered for relay system. The performance of AS- and PS-based IA relay systems is considered, as is a new energy cooperation (ECop) scheme that is proposed to improve system performance. Numerical results are provided to evaluate the performance of all schemes and it is shown from the simulations that the performance of proposed ECop outperformed both AS and PS.
Larvicidal activity of leaf extract of Millingtonia hortensis (Family: Bignoniaceae) against Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti.

Mosquitoes are the principal vectors of malaria and other vector borne diseases and contribute to major disease burden in India. Disease transmission can be interrupted by controlling the vectors using various methods. However, the extensive and unbalanced use of chemical insecticides have created problems like enhancing resistance of mosquito population to synthetic insecticides, pollution of environment and adverse effects on the non-target flora and fauna inhabiting the same aquatic habitat. These steadily growing problems, demand an intensive search for new products that are environmentally safe, targetspecific and degradable.
Principal‐agent relationships on the stewardship‐agency axis

This article provides an overview of the literature on nonprofit principal-agent relationships. It depicts the nature of agency theory and stewardship theory, analyzes the origin of their struggle within the nonprofit structure, and marks directions for a conciliatory approach. We open with an introduction to agency theory and discuss the two main components of its mathematical branch. We thereby contrast it with stewardship theory and elaborate on the arguments that can affect the position of nonprofit principal-agent relationships on the stewardship-agency axis. Analysis of the existing literature points to a lack of consensus as to which theory should be applied. We argue that the division of nonprofit principalagent relationships into board-manager and manageremployee interactions may help to clarify the balance between agency theory and stewardship theory and may lead to the establishment of a strongly founded theory on nonprofit principal-agent relationships. We close with a discussion of how this article may prove valuable to nonprofit policymakers and other empirical researchers.
Educational game design: game elements for promoting engagement

Engagement in educational games, a recently popular academic topic, has been shown to increase learning performance, as well as a number of attitudinal factors, such as intrinsic interest and motivation. However, there is a lack of research on how games can be designed to promote engagement. This mixed methods case study aimed to discover effective game elements for promoting 17-18 year old high school students' engagement with an educational game. Using within-case and cross-case analyses and triangulated data, 10 elements emerged and were categorized into the constructs of story, gameplay, and atmosphere. Examples and connections to the literature for each element are reported. Findings implicate that educational game design for both learning and engagement is composed of educational-game specific elements, game design for solely engagement is similar for both educational and entertainment games, and a gap on educational game design technique instead of theory should be addressed to further benefit educational game development.
Temporal Profiles of Instant Utility During Anticipation, Event, and Recall

We propose the anticipation-event-recall AER model. Set in a continuous time frame, the AER model formally links the three components of total utility i.e., utility from anticipation, event utility, and utility from recall. The AER model predicts the temporal profiles of instant utility experienced before, during, and after a given event. Total utility is calculated as the integral of instant utility. The model builds on the psychological elements of conceptual consumption, adaptation, and time distance. By virtue of its rich formulation, the AER model produces a wide set of insights and testable predictions, including the U shape of instant utility during anticipation and the optimal duration of anticipation for a given event. Using both real and hypothetical events, we provide empirical evidence in support of the main implications of the AER model. Data, as supplemental material, are available at http://dx.doi. org/10.1287/mnsc.2015. 2362 . This paper was accepted by James Smith, decision analysis.
The impact of postpartum post-traumatic stress disorder symptoms on child development: a population-based, 2-year follow-up study

Background Against the background of very limited evidence, the present study aimed to prospectively examine the impact of maternal postpartum post-traumatic stress disorder (PTSD) symptoms on four important areas of child development, i.e. gross motor, fine motor, communication and social–emotional development. Method This study is part of the large, population-based Akershus Birth Cohort. Data from the hospital's birth record as well as questionnaire data from 8 weeks and 2 years postpartum were used (n = 1472). The domains of child development that were significantly correlated with PTSD symptoms were entered into regression analyses. Interaction analyses were run to test whether the influence of postpartum PTSD symptoms on child development was moderated by child sex or infant temperament. Results Postpartum PTSD symptoms had a prospective relationship with poor child social–emotional development 2 years later. This relationship remained significant even when adjusting for confounders such as maternal depression and anxiety or infant temperament. Both child sex and infant temperament moderated the association between maternal PTSD symptoms and child social–emotional development, i.e. with increasing maternal PTSD symptom load, boys and children with a difficult temperament were shown to have comparatively higher levels of social–emotional problems. Conclusions Examining four different domains of child development, we found a prospective impact of postpartum PTSD symptoms on children's social–emotional development at 2 years of age. Our findings suggest that both boys and children with an early difficult temperament may be particularly susceptible to the adverse impact of postpartum PTSD symptoms. Additional studies are needed to further investigate the mechanisms at work.
Quality of life in the intergroup exemestane study: a randomized trial of exemestane versus continued tamoxifen after 2 to 3 years of tamoxifen in postmenopausal women with primary breast cancer.

PURPOSE To compare and describe the quality of life (QOL) of women allocated to tamoxifen or exemestane within the Intergroup Exemestane Study (IES). PATIENTS AND METHODS Postmenopausal women with primary breast cancer who were disease free after 2 to 3 years were randomly assigned to switch from tamoxifen to exemestane or continue with tamoxifen until 5 years of treatment were completed. A subset of IES centers participated in a QOL substudy. The Functional Assessment of Cancer Therapy-Breast (FACT-B) and endocrine subscale (ES) were administered before random assignment and at predefined follow-up times. The primary end point was the FACT-B composite Trial Outcome Index (TOI). Secondary end points included total FACT-B+ES score, total ES score, and severity of individual endocrine symptoms. This analysis reports QOL up to 24 months. RESULTS Five hundred eighty-two patients from eight countries were enrolled onto the substudy. Completion and return of questionnaires was excellent, with 85% available for analysis. QOL was generally good and stable over 2 years, with no clinically meaningful differences found between groups in TOI or ES. Prevalence of severe endocrine symptoms at trial entry was high for vasomotor complaints and sexual problems, which persisted for both groups during the study. No significant differences between groups were seen for any endocrine symptoms apart from vaginal discharge, which was more pronounced with tamoxifen (P < .001). CONCLUSION The switch from tamoxifen to exemestane neither increased nor decreased endocrine symptoms present after 2 to 3 years of tamoxifen; the switch also did not initiate significant reports of new symptoms. Results indicate that the clinical benefits of exemestane over tamoxifen are achieved without significant detrimental effect on QOL.
Proposed Protocol for Reading Images of Humeral Head Fractures

Fractures of the proximal humerus can be treated effectively but require proper characterization. None of the existing classifications intended to facilitate characterization have been satisfactory. We studied proximal humerus fractures using radiographs alone and radiographs plus computed tomography scans to ascertain which imaging studies were most useful to characterize these fractures. We designed an assessment protocol consisting of 17 parameters divided in four groups: cephalodiaphyseal relationship (six parameters), cephalotuberosity relationship (six parameters), humeral head (two parameters), and fracture fragment description (three parameters). The computed tomography scans were assessed using 11 parameters (the same parameters used for assessing radiographs except for the six cephalodiaphyseal parameters). Four observers analyzed the parameters in 30 selected fractures with biplanar radiographic projections (30 patients) and computed tomography scans (22 patients) on two occasions. We found good interobserver reliability and intraobserver reliability with radiographs alone for the cephalodiaphyseal parameters. The best interobserver reliabilities with radiographs plus computed tomography scans were with the number of fragments, displacement of the lesser tuberosity, and extraarticular or articular fractures. Computed tomography allows better assessment of some parameters in characterizing proximal humeral fractures. The use of a structured protocol in reading images seems useful and allows better reliability than reported for other approaches. Level of Evidence: Diagnostic study, Level III (study of nonconsecutive patients without consistently applied reference “gold” standard).

Chitinolytic bacteria from alkaline hypersaline Mono Lake, California, USA

Chitinolytic activity was detected in sediment and water-column samples from Mono Lake, California, USA, using fluorogenic analogues. In order to learn more about chitin degradation in Mono Lake, we analyzed the phylogenetic composition of bacterial assemblages in chitin-enrich- ment cultures and associated with Artemia monica exuvia. We also isolated chitinolytic bacteria from aerobic and anaerobic water and sediment samples. We screened these isolates for their ability to hydrolyze chitin analogs, for the formation of clearing zones on chitin plates, and for growth with chitin as the sole carbon and energy source. We characterized the isolates phylogenetically by deter- mining partial sequences of their 16S rRNA genes. Three ribotypes, most closely related to Paracoc- cus sp. MBIC4036 (AB025192), Arhodomonas sp. EL-201 (AJ315984), and Psychroflexus tropicus (AF513434), were only found in Mono Lake exuvium and chitin-enrichment clone libraries. Four ribo- types, retrieved solely from chitin enrichments, were closely related to Proteobacteria. The majority (73%) of the isolates we obtained were Gram-positive bacteria, and 70% of the Gram-positive iso- lates were capable of hydrolyzing at least 1 model substrate.
Genotyping of Helicobacter pylori in paraffin-embedded gastric biopsy specimens: relation to histological parameters and effects on therapy

OBJECTIVES:Colonization with Helicobacter pylori can lead to GI disease. Bacterial genotypes and host factors, such as acid production, can influence the progress of disease. We investigated H. pylori genotypes and histological parameters in the same paraffin-embedded gastric biopsy specimens.METHODS:Paraffin-embedded antrum and corpus biopsy samples from 75 gastroesophageal reflux disease patients were histologically examined and tested for H. pylori vacA (s and m regions), cagA, and iceA genotypes. Patients were investigated at baseline (58 H. pylori positive and 17 H. pylori negative) and after treatment with omeprazole with or without additional antibiotic therapy.RESULTS:Genotyping at baseline was complete in 52 (90%) of the 58 H. pylori positive patients. Multiple genotypes were detected in eight (14%) of these. Genotypes were highly consistent between antrum and corpus biopsy specimens at baseline and in follow-up samples. Genotypes from paraffin sections matched those from corresponding cultured strains in 10 selected cases. In the antrum, the degree of inflammation was associated with vacA s1 and cagA+ genotypes, and the degree of neutrophil activity was associated with the cagA+ genotype. In the corpus, the degree of inflammation was significantly associated with vacA s1, cagA+, and iceA1 genotypes and the degree of atrophy was associated with vacA s1, m1, and cagA+ genotypes, whereas the degree of neutrophil activity was associated with vacA s1 and cagA+ genotypes. vacA s2 and cagA− strains appeared more resistant to antibiotic therapy, irrespective of resistance to clarithromycin.CONCLUSIONS:Our findings confirm the relevance of the H. pylori genotypes for the severity of gastric disease and the efficacy of antibiotic therapy.
Contact and photocontact sensitivity to sunscreens

Clinical case A 55-year-old man had grown Pleurotus ostreatus for 5 years. He had a previous history of chromate dermatitis from the age of 20 years, with recurrent clinical manifestations that had disappeared 10 years previously, when he left the construction industry because of an accident. From around 6 years, he had had allergic rhinitis, with a total IgE of 361 kUI/L and with prick tests and RASTs highly positive to Parietaria officina/is and negative to other inhalant allergens. For around 3 years, red scaly vesicular lesions had been appearing on the hands, with reported episodes of spread to the upper and lower limbs, face and trunk. Clinical manifestations appeared simultaneously with cycles of harvest of the mushrooms. In particular, episodes of spread were associated with collecting the mushrooms in an advanced stadge of maturation, when the air inside the building was saturated with spores, visible as a dust. Patch tests, with the GIRDCA standard and agriculture series confirmed the already-known positivity to potassium dichromate 0.5% pet. , and found a new one to dinocap 1% pet. , used by the patient in the past as a pesticide. The lamellae, stem and spores of the mushroom, tested as is, all gave a positive reaction (02 ++I D4+ + .). 30 controls, 10 of them carrying out the same cultivation, were negative. Negative open and prick tests with Pleu,. Jtu;. , excluded immediate-type allergy.
Is non-Helicobacter pylori, non-NSAID peptic ulcer a common cause of upper GI bleeding? A prospective study of 977 patients.

BACKGROUND Non-Helicobacter pylori, non-NSAID ulcer is relatively common in Western countries. Whether it is a significant problem in the Orient is unclear. The aim of this study was to investigate the incidence of non-H pylori, non-NSAID ulcers presenting with GI bleeding. METHODS A prospective study was done of 1675 consecutive patients presenting with upper GI bleeding over a period of 12 months. Upper endoscopy was performed with biopsy specimens taken from the antrum and body of the stomach for a biopsy urease test (BUT) and histology for detection of H pylori. Exposure to nonsteroidal anti-inflammatory drugs (NSAID) or aspirin within 4 weeks of hospitalization was carefully scrutinized. A 6-week course of treatment with an H2-receptor antagonist was prescribed for patients who did not use an NSAID and had a negative BUT result. Follow-up endoscopy was performed to confirm H pylori status with a BUT and histology. Positive histology at either initial or follow-up endoscopy was used as the standard for diagnosing H pylori infection. RESULTS Among 977 patients who were found to have ulcer bleeding, 434 (44%) had exposure to aspirin or an NSAID. Of the 543 non-NSAID users, 431 (79.4%) had a positive BUT and 112 (20.6%) were BUT negative on initial endoscopy. Eighty-nine of 112 patients who were NSAID negative, BUT negative returned for follow-up endoscopy. Forty-nine of 89 (55.1%) were found to have a positive BUT and positive histology at follow-up endoscopy. Only 40 of 977 (4.1%) patients admitted with ulcer bleeding were confirmed to have non-H pylori, non-NSAID ulcers. CONCLUSIONS Non-H pylori, non-NSAID bleeding ulcer is uncommon. A negative BUT is unreliable for exclusion of H pylori infection during the acute phase of ulcer bleeding.
Newcastle disease antibody levels in chickens after vaccination with oil emulsion adjuvant killed vaccine

Chicks vaccinated with live Hitchner B1 Newcastle disease vaccine at 17 days old and subsequently re-vaccinated with an oil emulsion killed Newcastle disease vaccine at either 38 or 52 days old showed high and persistent HAI antibody levels for at least eight months. Re-vaccination of these birds at 17 weeks old caused a further rise in antibody level to log212 which, even at 38 weeks, had dropped only to log210. Chicken primarily vaccinated with oil emulsion killed vaccine at six weeks old developed HAI antibody levels after four to five weeks of log29 which re-vaccination four weeks later increased to log211. Chicken given killed aluminium hydroxide adjuvant Newcastle disease vaccine were serologically HAI negative 13 weeks after vaccination while those given the oil emulsion vaccine still showed an antibody level of log28. Groups of birds inoculated with oil emulsion vaccine and then, at 20 weeks old, challenged with virulent Newcastle disease showed a 100 per cent survival rate. The particular merits of oil emulsion killed Newcastle disease vaccine for laying and breeding birds are discussed.

Behaviour Problems in Children with Intellectual Disabilities in a Resource‐Poor Setting in India – Part 1: Association with Age, Sex, Severity of Intellectual Disabilities and IQ

BACKGROUND Behaviour problems are most common in people with intellectual disabilities. Nature of behaviour problems can vary depending upon the age, sex and intellectual level (IQ). OBJECTIVES This study examined the distribution of behaviour problems across intellectual disability categories and their association with IQ age and sex in children with intellectual disabilities. METHODS This is a cross-sectional study design. A total of 104 participants (57 males and 47 females), aged 3-18 years, with intellectual disabilities were administered The Behavioural Assessment Scale for Indian Children with Mental Retardation (BASIC-MR). RESULTS It was found that violent and destructive, temper tantrum and self-injurious behaviours were differently distributed with reference to intellectual disability levels (P > 0.05) but cumulative scores per se problem behaviours did not vary with the level of intellectual disabilities. IQ showed a significant positive correlation with destructive and violent and misbehaves with other; and a significant negative correlation with temper tantrums and self-injurious behaviours. Age was significantly, positively associated with violent and destructive, odd, and hyperactive behaviours and inversely with self-injurious problem behaviours. There was no significant relationship between the sex of the child and problem behaviours. There was no significant interactive effect of sex and level of intellectual disabilities of the child on problem behaviours. CONCLUSION Behaviour problems, in general, are not equally distributed in all categories of intellectual disabilities. Relationship between behaviour problems and age, sex and IQ may not be uniform. But specific behaviours are more associated with specific age group and intellectual disability levels.
Clinical and laboratory profile of enteric fever in children in northern India

The diagnosis of enteric fever poses several problems due to the non-specific and wide array of clinical features. A five-year retrospective study enrolling 136 culture-proven cases of enteric fever was undertaken in order to estimate the clinical and laboratory characteristics, fever clearance time and outcome. The common symptoms and signs were: fever, vomiting, cough, anorexia, diarrhoea, abdominal pain, hepatomegaly, splenomegaly and coated tongue. Enteric fever should be considered in the differential diagnosis of febrile patients with abdominal symptoms.
Retrospective view of airborne dust levels in workplace of a chrysotile mine in Ural, Russia.

The Bazhenovskoye chrysotile asbestos deposit has been exploited for 115 years. All the technological operations in the quarry are accompanied by the formation of high-dispersion asbestos-containing aerosols. The dust concentrations at the miner's working places for the last 30 years (1970-2000) were at or below the Russian MACs(m.s.) level (4.0 mg/m3). The seasonal precipitation amount in the deposit area causes a rise in dust content in certain periods. The maximum density of asbestos respirable fibres exceeded 2.7 f/cm3. All the identified fibres belonged to chrysotile asbestos, and no amphibole asbestos, such as tremolite asbestos, has been identified. An excessive dust level remains, despite the dust content level decrease, at the work sites of oversized lump drillers and unloaders, and oncopathology heightened risk remains in these occupational groups, as a result.
Polishing Machine Based on High-Pressure Water Jet

— The design of high pressure water jet based polishing equipment and its fabrication conducted in this study is reported herein, together with some preliminary test results for assessing its applicability for HMA surface polishing. This study also provides preliminary findings concerning the test variables, such as the rotational speed, the water jet pressure, the abrasive agent used, and the impact angel that were experimentally investigated in this study. The preliminary findings based on four trial tests (two on large slab specimens and two on small size gyratory compacted specimens), however, indicate that both friction and texture values tend to increase with the polishing durations for two combinations of pressure and rotation speed of the rotary deck. It seems that the more polishing action the specimen is subjected to; the aggregate edges are created such that the surface texture values are increased with the accompanied increase in friction values. It may be of interest (but which is outside the scope of this study) to investigate if the similar trend exist for HMA prepared with aggregate source that is sand and gravel.
