The many faces of somatosensory amplification: The relative contribution of body awareness, symptom labeling, and anxiety
Authors: Köteles Ferenc , Doering Bettina K
Published: June 2015

The questionnaire study aimed to evaluate the relative contribution of body awareness, subjective symptoms, and anxiety to the construct of somatosensory amplification in both healthy controls ( n = 475) and patients visiting their general practitioner ( n = 236). Regression analysis explained 52.0 percent of total variance of the somatosensory amplification scale scores. Body awareness was the most influential predictor ( β = 0.489, p < 0.001) when considering all predictors simultaneously. The results suggest that dispositional interoceptive focus, as indicated by body awareness, may be an important aspect of somatosensory amplification, over and above dispositional anxiety or subjective symptom report.
Social networking sites and participatory reluctance: A case study of Gaydar, user resistance and interface rejection
Authors: Cassidy Elija
Published: June 2015

This article conceptualises ‘participatory reluctance’ as a particular orientation to social media that problematises binarised notions of connection and disconnection in social networking sites. It qualitatively examines how the concept has functioned within gay men’s social networking service, Gaydar, among 18- to 28-year-old users of the site in Brisbane, Australia. Participatory reluctance is shown to be a central aspect of the culture of this space, fostered among the studied demographic by the convergence of the growing global push for marriage equality and increasing normalisation of the kinds of gay male identities commonly adopted among this group, with three key factors rooted primarily in Gaydar’s design: (1) young users’ perceptions of the site as a space for procuring casual sex, (2) their perceptions of the imagined user as embodying existing stereotypes of gay masculinity and (3) a lack of genuine alternatives in terms of niche digital spaces for gay men’s social networking.
Catch Me If You Can
Authors: Hlasny Vladimir , Kolaric Sascha
Published: June 2015

The central hypothesis of this study is that relationships develop systematically between referees and teams and affect referees’ decisions. Referees’ travel distance to respective stadiums and count of matches refereed for respective teams are used to measure long-term relationships. We find some evidence that the count of referee–team interactions affects disciplinary cautions in lower divisions of the English Football League. This is less evident in higher divisions where, however, distances between referees’ hometowns and stadiums appear to play a role. The influence of distance further increases with the extent of referees’ experience with the respective teams.
Application of clustering technique for definition of generic objects in a material database
Authors: Zhao Jianhua , Plagge Rudolf , Ramos Nuno MM , Simões M Lurdes , Grunewald John
Published: June 2015

In this article, generic objects are introduced into material databases of building simulation tools. A generic object has the common characteristics of one type of specific object and can represent specific ones in the simulation. The application of generic objects only requires some general design information; thus, it is convenient for the simulation users who do not have a detailed knowledge of building specification in the early design stage. First, the method to uncover the underlying cluster structure in the dataset is illustrated. Clustering of the objects depends on the adopted clustering variables and clustering procedure. Therefore, different clustering techniques are applied to agglomerate specific materials into different clusters, and the clustering solutions are compared for validation. Generic synthesis is then conducted to derive the generic material from each identified cluster. The approach on how to apply generic materials to fill in missing values of the incomplete material data is also described.
An exploration of the working life and role of the ward manager within an acute care hospital organisation
Authors: Pegram Anne M , Grainger Michelle , Jones Kathryn , While Alison E
Published: June 2015

The ward manager’s role is a complex one that involves meeting financial targets, responding to changes in organisational structures and ensuring the delivery of quality patient care. Whilst the ward manager’s role remains key to service delivery, there has been limited research on the current role from the perspective of ward managers. A survey of ward managers, exploring aspects of their working lives and potential enablers of the ward manager role, is described. The variety of activities within the role was a source of job satisfaction despite the challenge of ‘keeping on top of everything’. Potential role enablers included having protected time for the managerial aspects of the role. The study findings indicate the need to understand the role of the ward manager with particular reference to job satisfaction, and the underpinning support required to enable ward managers to execute the role effectively.
Outbreak column 17: Situational Awareness for healthcare outbreaks
Authors: Curran Evonne T
Published: June 2015

Outbreak column 17 introduces the utility of Situation Awareness (SA) for outbreak management. For any given time period, an individual or team’s SA involves a perception of what is going on, meaning derived from the perception and a prediction of what is likely to happen next. The individual or team’s SA informs, but is separate to, both the decisions and actions that follow. The accuracy and completeness of an individual or team’s SA will therefore impact on the effectiveness of decisions and actions taken. SA was developed by the aviation industry and is utilised in situations which, like outbreaks, have dynamic, i.e. continuously changing problem spaces, and wherein a loss of SA is likely to lead to both poor decision-making and actions with potentially fatal consequences. The potential benefits of using SA for outbreaks are discussed and include: (1) retrospectively to identify if poor decision-making was a result of a poor SA; (2) prospectively to identify where the system is weakest; and (3) as a teaching tool to improve the skills of individuals and teams in developing a shared understanding of the here and now.
Vasospasm Risk in Surgical ICU Patients With Grade I Subarachnoid Hemorrhage
Authors: Lominadze George , Lessen Samantha , Keene Adam
Published: June 2015

Aneurysmal subarachnoid hemorrhage (SAH) is associated with high mortality. The initial hemorrhage causes death in approximately 25% of patients, with most subsequent mortality being attributable to delayed cerebral ischemia (DCI). Delayed cerebral ischemia generally occurs on post-bleed days 4 through 20, with the incidence peaking at day 8. Because of the risks of DCI, patients with SAH are usually monitored in an intensive care unit (ICU) for 14 to 21 days. Unfortunately, prolonged ICU admissions are expensive and are associated with well-documented risks to patients. We hypothesized that a subset of patients who are at low risk of DCI should be safe to transfer out of the ICU early. All patients admitted to Montefiore Medical Center from 2008 to 2013 with grade I SAH who had their aneurysms successfully protected, had an uncomplicated postoperative course, and had no clinical or ultrasonographic evidence of DCI after day 8 were retrospectively studied. The primary outcome was clinical or ultrasonographic evidence of the development of DCI after day 8. Secondary outcomes included length of ICU and hospital stay and hospital mortality. Forty patients who met the above-mentioned criteria were identified. Of these, only 1 (2.5%) developed ultrasonographic evidence of DCI after day 8 but required no intervention. The mean length of stay in the ICU was until post-bleed day 13, and the mean hospital length of stay was until post-bleed day 14. The in-hospital mortality was 0 of 40. Thus, we identified a low-risk subset of patients with grade I SAH who may be candidates for early transfer out of the ICU.
The legislative consequences of internal conflict and inter-party divisions
Authors: Haber Matthias
Published: June 2015

Governments must respond quickly to pressing economic and societal problems. However, institutional rules, public opinion and unanticipated world events often delay the legislative process. Building on theories of legislative decision-making and intra-party politics, this paper shows that the speed at which bills pass is also driven by the governing party’s internal cohesiveness and its ideological distance to the opposition. Governing parties that are internally divided have greater difficulty in forming the legislative majorities necessary to pass laws quickly, especially if their preferences are further away from the opposition. I test these hypotheses using a novel collection of laws passed in the UK Parliament and conference speeches given by Labour and Conservative party members over a 10-year period. I use automated text classification techniques to determine the relative location of actors’ preferences and the level of intra-party disagreement. I then predict the duration of lawmaking based on the government’s recent internal level of conflict and its distance to the opposition. The results complement mounting evidence that parties’ internal policy divisions hold important implications for parties’ performance in government.
Unusually Located Stroke After Chemotherapy in Testicular Germ Cell Tumors

Authors: Петухов  , Petukhov D.
Published: June 2015

Theoretical basis for the Russian national logistics system (NLS) development strategy have been exposed in this paper. An area, methodological principles and approaches, use of which will provide the most adequate solution to this problem, have been defined. Ways for theoretical justification of this approach have been proposed, key definitions have been defined. It has been proved, that it is necessary to use a methodological basis for consideration of the logistics system as a complex system in development, where such development is determined by many factors, both external and internal origin, as well as by interdependence of such system’s structural elements and functions. It has been shown, that this approach cannot be implemented without a clear understanding of difficulties related to such systems managing, the more so this managing should be realized in accordance with a strict plan, which considers all details and private aspects.

Społeczne podstawy systemu partyjnego – zarys tematyki w perspektywie Polski
Authors: Kamiński Paweł
Published: June 2015

This paper presents the ongoing discussion about Polish party system formation and its foundations among society. It also reviews the the literature that has studied the origins of cleavage based party systems, originally presented by Lipset and Rokkan, as well as theoretical and empirical assessments. For a long period of time Polish party system was depicted as very unstable, lacking any sign of institutionalization and where voters had showed no strong ties to political parties. This paper presents an argument that since 2004 this situation has started to change. In the second part of the review it is suggested that the current state of the Polish party system gives us strong indications that the new cleavage may have come into being, namely, between liberal and solidarity values, which convincingly correlates with electorates of two biggest parties: Law and Justice (PiS) and Civic Platform (PO).
Limitations to assess the impact of rural development policy in the Puglia region: The case of measure 121 – Axes I
Authors: Pazienza Pasquale , Caruso Donatello , Vecchione Vincenzo
Published: June 2015

In this work, some specific aspects of the Rural Development Plan of the Puglia Region (in Southern Italy) for the period 2007-2013 are analyzed and the limitations characterizing the possibility of building an analysis framework aimed at understanding how it actually affects the regional agricultural system are highlighted. More specifically, by referring to a specific measure of the rural development program (Measure 121 of Axes I), the aim is to verify whether the investment activity implemented has actually generated some positive results which can induce us to say that the EU budget devoted to rural development is well spent. In order to achieve this purpose, the authors of the present work have worked at gathering all the information available at the Puglia Region Authority. Nevertheless, this is not helpful for the type of the analysis the authors would like to conduct. The observation of the gathered data, in fact, makes the authors observe the existence of severe limitations deriving from the way in which the Regional Authority manages the data collection. The main aim of this work is to present a framework of analysis which might be used for policy evaluation purposes and to discuss what should be further required for a useful completion of the dataset with the aim of making it the subject of empirical analyses.
Impacto de los usos del suelo y erosión en cuencas vertientes del sur del País Valenciano
Authors: Vera Rebollo José Fernando , Marco Molina Juan Antonio
Published: June 2015

Las nuevas condiciones socio-económicas y el nivel técnico han supuesto el abandono o la transformación de los aprovechamientos tradicionales en las cuencas vertientes y, en determinados espacios, la introducción de nuevos usos caracterizados por la creciente capitalización del suelo. Todo ello ha supuesto la aparición o acentuación de fenómenos erosivos, tales como cárcavas y arramblamientos (piping, gullies) que crean una inestabilización morfogenética de las cuencas y contribuyen a la desorganización de las escorrentías, con una clara repercusión negativa en los episodios de crecida. Se plantea la necesidad de una ordenación, cuya escala es el organismo de cuenca, y la puesta en marcha de medidas de protección y regulación de usos.
Ordenación y gestión de recursos hídricos en un ámbito subárido: el abastecimiento de los municipios integrados en la Mancomunidad de los Canales del Taibilla
Authors: Vera Rebollo José Fernando , Morales Gil Alfredo
Published: June 2015

El agua es, sin lugar a dudas, el motor impulsor del desarrollo socioeconómico de las tierras del sureste peninsular ibérico; pero su escasez ha impuesto tradicionalmente una utilización razonada del recurso, al tiempo que se aseguraba su uso fuera de los espacios próximos a los cauces naturales, para lo que se hacía necesaria la construcción de una gran red de distribución. Con la creación de la Mancomunidad de los Canales del Taibilla cristaliza la vieja aspiración de garantizar el abastecimiento de núcleos urbanos y entidades estatales. Es así como se sientan las bases que impulsarían el desarrollo industrial, a partir del decenio de los cincuenta y, desde los años sesenta, el despegue de la actividad turística en el litoral. Los resultados conseguidos merced a este sistema de abastecimiento son evidentes, pero el actual ritmo de desarrollo urbano y demográfico de las principales ciudades y la nueva etapa expansionista que vive la franja litoral han puesto de relieve las limitaciones del Organismo, condicionado por la disponibilidad de recursos, por lo que este trabajo trata de esclarecer su situación actual y perspectivas de futuro.

Some Comments on Compositional Analysis in Management and Production Engineering
Authors: Vives-Mestres Marina , Martín-Fernández Josep A.
Published: June 2015

This paper introduces the most basic concepts of the compositional analysis of data with a simple but real example form the Management and Production Engineering (MPE) field. Compositional Data (CoDa) are vectors of positive elements that represent parts of a whole and are widely found in MPE, i.e. production times, resource composition, percentage utilization of work stands, waste components. . . The need for an analysis based on ratios of components (or better log-ratios of components) is illustrated step by step, and findings are compared to the corresponding standard methods applied to raw compositions. The paper also exposes the principles of CoDa analysis and presents two basic descriptive tools suitable for CoDa: the clr-biplot and the CoDa dendrogram. The example is a time series, from 1994 to 2013, of motor vehicle production in 8 countries and regions.
Emission of Gravitational Waves from a Magnetohydrodynamic Dynamo in the Center of the Sun
Authors: Winterberg Friedwardt
Published: June 2015

By Birkhoff’s theorem a spherical symmetric convection pattern, as it is assumed to exist for main sequence stars as our sun, cannot lead to the emission of gravitational waves, but all stars that have a magnetic field generated by a magnetohydrodynamic dynamo must by a theorem of Cowling have a non-spherical symmetric convections pattern and for this reason have to emit gravitational waves. The intensity of the thusly emitted gravitational waves depends on the efficiency of this dynamo, expressed by the departure from a spherical convection pattern. The magnitude of the asymmetry is determined by a solution of Elsaesser’s dynamo equations which only recently has become possible with supercomputers. The waves are emitted through large mass motions in the center of the sun by a thermonuclear fusion reaction-driven magnetohydrodynamic dynamo, with thermomagnetic currents in the tachocline shielding the strong magnetic field in the solar core. Using the moon as a large Weber bar, the gravitational waves are focused into the lunar shadow by Poisson diffraction where their effect might become observable during a total solar eclipse.

Authors: Daniels Lynne Allison , Mallan Kimberley Margaret , Nicholson Jan Maree , Thorpe Karen , Nambiar Smita , Mauch Chelsea Emma , Magarey Anthea
Published: June 2015

OBJECTIVE:

Report long-term outcomes of the NOURISH randomized controlled trial (RCT), which evaluated a universal intervention commencing in infancy to provide anticipatory guidance to first-time mothers on “protective” complementary feeding practices that were hypothesized to reduce childhood obesity risk.

METHODS:

The NOURISH RCT enrolled 698 mothers (mean age 30.1 years, SD = 5.3) with healthy term infants (51% female). Mothers were randomly allocated to usual care or to attend two 6-session, 12-week group education modules. Outcomes were assessed 5 times: baseline (infants 4.3 months); 6 months after module 1 (infants 14 months); 6 months after module 2 (infants 2 years) and at 3.5 and 5 years of age. Maternal feeding practices were self-reported using validated questionnaires. BMI Z-score was calculated from measured child height and weight. Linear mixed models evaluated intervention (group) effect across time.

RESULTS:

Retention at age 5 years was 61%. Across ages 2 to 5 years, intervention mothers reported less frequent use of nonresponsive feeding practices on 6 of 9 scales. At 5 years, they also reported more appropriate responses to food refusal on 7 of 12 items (Ps ≤ .05). No statistically significant group effect was noted for anthropometric outcomes (BMI Z-score: P = .06) or the prevalence of overweight/obesity (control 13.3% vs intervention 11.4%, P = .66).

CONCLUSIONS:

Anticipatory guidance on complementary feeding resulted in first-time mothers reporting increased use of protective feeding practices. These intervention effects were sustained up to 5 years of age and were paralleled by a nonsignificant trend for lower child BMI Z-scores at all postintervention assessment points.
Liming with dolomite reduces the efficacy of the biocontrol fungus Trichoderma koningiopsis against cabbage clubroot
Authors: Botero Andrea , Gómez Iván , Benítez Édgar , García Celsa
Published: June 2015

Cabbage clubroot is a major constraint for the production of cruciferous species. This research aimed to explore the effect of Trichoderma koningiopsis (as the wettable powder formulated product Tricotec®) and dolomite on the disease and crop growth of cabbage. This study was carried out in a field with a prolonged history of clubroot incidence. The trial was set up in a randomized complete block design with five repetitions. The following treatments were applied: 0) absolute control; 1 and 2) liming with dolomite at 1.0 and 2.1 t ha-1; 3) Tricotec® at 200 g ha-1; 4) combination of treatments 1 and 3; 5) combination of treatments 3 and 4. The treatment with just Tricotec® applications gave the lowest disease incidence and severity and the heaviest plant dry weight. Joint applications of Tricotec® and dolomite at 2.1 t ha-1 reduced the crop growth variables and had the highest disease intensity. The Trichoderma concentration in the soil was increased by a factor of 10 in the plots that received just Tricotec®, but not in the limed plots. These results showed that T. koningiopsis, in a Tricotec® formulation, is a promising candidate for the control of cabbage clubroot and that its biological activity is affected by dolomite when applied jointly at 2.1 t ha-1.

Published: June 2015

OBJECTIVES: To analyze the dietary profile of participants who used two health promotion services located in socially vulnerable areas in a Brazilian metropolis. METHODS: A cross-sectional comparative study was conducted with participants (n = 370) aged ≥ 20 years who joined two services of the Academias da Cidade program in Belo Horizonte, Minas Gerais, Brazil. The study participants engaged in physical activity and nutritional education actions directed by the services from 2009 to 2010. The sociodemographic and economic conditions and health and nutrition profiles of each individual were assessed. RESULTS: Participants from a high social-risk who used the service did not demonstrate adequate intake of vegetables (54.6 versus 43.6%; p = 0.038), sweets (33.5 versus 23.2%; p = 0.030), soft drinks (28.5 versus 11.9%; p < 0.001), artificial juice (34.7 versus 22.6%; p = 0.011), and processed meat (48.8 versus 32.7; p = 0.002). However, in the other service, lower social vulnerability, a higher prevalence of abdominal adiposity (60.7 versus 43.0%; p = 0.004) and consumption of high-fat meat products (53.0 versus 36.5%; p = 0.002) was observed. CONCLUSION: Participants who used both services demonstrated inadequate food intake compatible with the development of chronic disease profiles. However, the participants in each service were distinct from each other. This suggests that promotion of healthy eating should to contemplate the territory and its interface with people health.
A pan-university open online course approach to EOL academic literacy for tertiary students
Authors: Carey Stephen
Published: June 2015

Canada and the academic world have changed dramatically since the Bilingualism and Biculturalism Reports and the implementation of French immersion programs in Canada a half century ago. From the original theme of bilingualism, equality and the balancing of French and English in Canada, globalization and immigration have produced a different model of bilingualism in a multilingual and multicultural Canada situated in a global English dominant academic network. This paper addresses the academic world dominance of English and the necessity of the majority of the world’s English speakers, who are not native speakers of English but speak English as an “other” language (EOL), as well as the minority of English speakers for whom English is their dominant language, to attain higher levels of academic literacy for the globalized world of academia. All of the approaches for EOL online immersion instruction proposed here can also be exploited to raise the French academic literacy of French immersion students and faculty for tertiary education.
Spinal intraosseous epidural arteriovenous fistula with perimedullary drainage obliterated with Onyx embolization: case report
Authors: Ou Chang-Hsien , Wang Hao-Kuang , Yang Tzu-Hsien , Liang Cheng-Loong , Wong Ho-Fai
Published: June 2015

The authors report an extremely rare case of spinal intraosseous epidural arteriovenous fistula (AVF) with perimedullary vein reflux causing symptoms of myelopathy. The intraosseous fistula tracts were completely obliterated with Onyx embolic agent, resulting in a total resolution of symptoms. The unique features of this case include the rare location of the fistula in the vertebral body and the association of the fistula with a compressive fracture. Imaging studies confirmed these hemodynamic findings and provided clarity and direct evidence regarding the association of epidural AVF formation with the vertebral compressive fracture. The authors also propose a possible disease evolution based on the previously adduced reflux-impending mechanism.

Assessment of Radiation Doses for Lungs due to Some Radionuclides Released from a Hypothetical Nuclear Power Reactor Accident
Authors: Khan Md Moniruzzaman , Quddus AHM Ruhul , Akramuzzaman Mir Md , Mollah Abdus Sattar
Published: June 2015

Different radionuclides are emitted from the reactor core after the nuclear accident. These radionuclides are entered into human body through different pathways, which damage the cells. The dose consequence to the sensitive organ like lungs of human body is considered in the present study to show the dose effect for various radionuclides from a hypothetical nuclear reactor accident. The calculations were made with the in-house developed computer program RaDARRA. Cardinal directions like E, ENE, ESE, N, NE, NNE, NNW, NW, S, SE, SSE, SSW, SW, W, WNW and WSW are considered to observe the dose effect along the directions. For the calculations, lungs dose arising from 8 radionuclides e.g., 89Sr, 91Y, 95Zr, 95Nb, 131I, 133I, 140Ba and 144Ce have been considered. Of all these radionuclides the maximum and minimum dose contribution mainly come from 144Ce (30%) and 95Nb (4.43%). It is marked that dose is maximum along North East (NE) direction for all the distances and for all types of the radioisotopes. Methodology used in the present study can also be utilized for any type of severe accident and any type of reactor power. DOI: http://dx.doi.org/10.3329/bjnm.v17i1.22489 Bangladesh J.

Published: June 2015

The purpose of this study was to investigate the additional benefit of single photon emission computed tomography/computed tomography (SPECT/CT) over whole-body planar bone scintigraphy (planar BS) and SPECT for the detection of bone metastases in breast cancer patients. Materials & methods: Of 112 consecutively examined patients with histologically confirmed breast carcinoma who underwent bone scintigraphy, 39 required further evaluation by SPECT/CT (n= 23) and SPECT alone (n = 16) because a definite diagnosis could not be established using whole body planar BS alone. The 23 SPECT/CT studies were retrospectively evaluated by two nuclear medicine physicians for planar BS and SPECT images, and one nuclear medicine physician and one radiologist for SPECT/CT on consensus. Each focus of abnormal tracer uptake was recorded for differentiating malignant from benign bone lesions. Clinical and imaging follow-up were used as a reference standard. Results: A total of 72 lesions were evaluated in 23 patients examined by three types of imaging modalities. In 57 of the 72 evaluated lesions, the results of planar BS, SPECT and SPECT/CT were concordant; 52 of the 57 lesions were interpreted as malignant and 5 lesions as benign by all modalities. In 15 of the 72 lesions, consensus reading of fused SPECT/CT images changed the image interpretation of 15 planar BS scans and 9 of the 15 SPECT scans: 7 lesions previously interpreted as benign (on both planar BS and SPECT) were re-classified as malignant and 8 lesions (8 by planar BS and 2/8 by SPECT) previously interpreted as malignant were reevaluated as benign. The highest diagnostic gain was in the thoracolumbar spine, thoracic cage & pelvis. The overall accuracy of SPECT/CT was significantly higher on a lesion-based analysis than planar BS and SPECT (100%vs 79%, p < 0.0001 and 100% vs 83%, p = 0.003). Compared to planar BS and SPECT, the results of SPECT/CT changed diagnosis or treatment in 5/23 patients (21.7%). 39 Conclusion: The hybrid imaging system with SPECT/CT is a feasible technique yielding coregistered dual-modality images. The addition of SPECT/CT improves the diagnostic accuracy for the correct interpretation of bony lesions in breast cancer patients undergoing bone scanning for metastases. SPECT/CT should be routinely used in the work up of postoperative breast carcinoma patients with simultaneous CT evaluation to identify metastatic lesions not detected on bone scintigraphy.

High dose I-131 therapy is administered to thyroid cancer patients after thyroidectomy. In the treatment process when a radiopharmaceutical is administered to patients, they become a mobile source of radiation. After the treatment, contamination may arise from large amount of activity, which is excreted during the period of hospitalization. To reduce the rate of exposure it is essential to monitor workplace. This study determines the rate of radiation exposure in the room where the patient stays during the period of hospitalization as well as the adjacent rooms and surrounding areas.

Published: June 2015

The study was carried out to know the gross morphological and morphometrical changes of major lymphoid organs of chemotherapy treated chickens during the period from July to September 2004 in the Department of Anatomy and Histology, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh. The 12-day-old 16 chickens (Vencobb broiler) were divided into four groups viz, group A, group B, and group C that were treated with cyclophosphamide @ 3 mg / kg body weight intramuscularly, vincristine @ 0.07 mg /kg body weight intramuscularly and the combination of the former two drugs using same dose and route for 3 consecutive days respectively and group D was kept as untreated control. After 7 days of last chemotherapy all birds were weighed and killed one by one through cervical subluxation. The body weights of the chemotherapy treated groups were decreased in comparison to control but more decreased in cyclophosphamide treated chickens. The major lymphoid organs (thymus, bursa of Fabricius, spleen and cecal tonsils) were exposed through ventral neck and abdominal dissection and grossly atrophy of the major lymphoid organs was observed in the chemotherapy treated chicken than the control chicken. After collection, the major lymphoid organs were weighed with the help of electric balance one by one. The weights of major lymphoid organs reduced in the chemotherapy treated chickens than the control chickens but the weight of lymphoid organs more reduced in the cyclophosphamide treated chickens. The result of the present study revealed that the size and weight of the major lymphoid organs of the chemotherapy treated chicken decreased in comparison to control chicken. These results indicated that the reduction of weight of major lymphoid organs was due to the action of drug in the lymphoid organs of chemotherapy treated chickens.
Personal Information Leaks with Automatic Login in Mobile Social Network Services

To log in to a mobile social network service (SNS) server, users must enter their ID and password to get through the authentication process. At that time, if the user sets up the automatic login option on the app, a sort of security token is created on the server based on the user’s ID and password. This security token is called a credential. Because such credentials are convenient for users, they are utilized by most mobile SNS apps. However, the current state of credential management for the majority of Android SNS apps is very weak. This paper demonstrates the possibility of a credential cloning attack. Such attacks occur when an attacker extracts the credential from the victim’s smart device and inserts it into their own smart device. Then, without knowing the victim’s ID and password, the attacker can access the victim’s account. This type of attack gives access to various pieces of personal information without authorization. Thus, in this paper, we analyze the vulnerabilities of the main Android-based SNS apps to credential cloning attacks, and examine the potential leakage of personal information that may result. We then introduce effective countermeasures to resolve these problems.
Comparison of Suspended Branch and Direct Infestation Techniques for Artificially Infesting Hemlock Seedlings with the Hemlock Woolly Adelgid for Resistance Screening
Authors: Powers Zaidee , Mayfield Albert , Frampton John , Jetton Robert
Published: June 2015

The hemlock woolly adelgid (Adelges tsugae Annand) is an invasive forest pest in eastern North America that has caused significant decline and mortality in populations of eastern hemlock (Tsuga canadensis (L.) Carr.) and Carolina hemlock (T. caroliniana Engelm.). The breeding of adelgid-resistant genotypes for reforestation activities is still in the early development phases, and most resistance screening programs have depended on labor-intensive direct artificial infestation techniques for introducing adelgids to target seedlings. We investigated the timing and effectiveness of a potentially less labor-intense suspended branch infestation technique compared to two levels of a direct infestation method. Results indicated that peak crawler emergence from adelgid infested hemlock branches occurred within a 10 to 14 day period and that crawler emergence was higher from non-hydrated compared to hydrated branches. Greater infestation pressure was achieved when using progrediens crawlers compared to sistens crawlers. In 2013, when the infestation attempts were most successful, the suspended branch technique induced the same or higher adelgid densities on target seedlings as the direct infestation techniques. Assuming an initial investment in infrastructure, the suspended branch approach could be a more time and cost effective method for inducing adelgid infestations for resistance screening of large numbers of candidate trees.

Risky outdoor play has been associated with promoting children’s health and development, but also with injury and death. Risky outdoor play has diminished over time, concurrent with increasing concerns regarding child safety and emphasis on injury prevention. We sought to conduct a systematic review to examine the relationship between risky outdoor play and health in children, in order to inform the debate regarding its benefits and harms. We identified and evaluated 21 relevant papers for quality using the GRADE framework. Included articles addressed the effect on health indicators and behaviours from three types of risky play, as well as risky play supportive environments. The systematic review revealed overall positive effects of risky outdoor play on a variety of health indicators and behaviours, most commonly physical activity, but also social health and behaviours, injuries, and aggression. The review indicated the need for additional “good quality” studies; however, we note that even in the face of the generally exclusionary systematic review process, our findings support the promotion of risky outdoor play for healthy child development. These positive results with the marked reduction in risky outdoor play opportunities in recent generations indicate the need to encourage action to support children’s risky outdoor play opportunities. Policy and practice precedents and recommendations for action are discussed.

Objective: We aimed to investigate whether free fatty acid (FFA) levels in hypertensive patients result from increased blood pressure or the accompanying condition of insulin resistance (IR). Furthermore, we aimed to study the role of IR in the onset and development of hypertension and then provide a basis for the prevention and treatment of hypertension and metabolic syndrome (MS). Design and Methods: The study included 68 essential hypertensive patients without IR, 87 normotensive subjects with IR, 82 essential hypertensive patients with IR and 74 normotensive subjects without IR. Analysis of covariance was used to compare FFA concentrations among the four groups to determine the association between FFA concentrations and hypertension and IR. Results: A significant difference in FFA concentrations among the four groups was found using a one-factor analysis of variance (p < 0.001). A significant difference was also found among the adjusted means of the four groups (essential hypertensive patients with IR vs. normotensive subjects without IR: 0.703 mg/L vs. 0.516 mg/L, p < 0.001; essential hypertensive patients with IR vs. normotensive subjects with IR: 0.703 mg/L vs. 0.525 mg/L, p < 0.001; essential hypertensive patients with IR vs. essential hypertensive patients without IR: 0.703 mg/L vs. 0.579 mg/L, p = 0.002; normotensive subjects with IR vs. normotensive subjects without IR: 0.525 mg/L vs. 0.516 mg/L, p = 0.007; essential hypertensive patients without IR vs. normotensive subjects without IR: 0.579 mg/L vs. 0.516 mg/L, p < 0.001). However, no significant interaction was detected between IR and hypertension regarding the FFA concentration. Conclusions: FFA is an independent factor for IR and hypertension among Uyghur adults in a rural area of Xinjiang.
Acetate Metabolism in Anaerobes from the Domain Archaea
Authors: Ferry James
Published: June 2015

Acetate and acetyl-CoA play fundamental roles in all of biology, including anaerobic prokaryotes from the domains Bacteria and Archaea, which compose an estimated quarter of all living protoplasm in Earth’s biosphere. Anaerobes from the domain Archaea contribute to the global carbon cycle by metabolizing acetate as a growth substrate or product. They are components of anaerobic microbial food chains converting complex organic matter to methane, and many fix CO2 into cell material via synthesis of acetyl-CoA. They are found in a diversity of ecological habitats ranging from the digestive tracts of insects to deep-sea hydrothermal vents, and synthesize a plethora of novel enzymes with biotechnological potential. Ecological investigations suggest that still more acetate-metabolizing species with novel properties await discovery.
Tension-Tension Fatigue Behavior of Unidirectional C/Sic Ceramic-Matrix Composite at Room Temperature and 800 °C in Air Atmosphere
Authors: Li Longbiao
Published: June 2015

The tension-tension fatigue behavior of unidirectional C/SiC ceramic-matrix composite at room temperature and 800 °C under air has been investigated. The fatigue hysteresis modulus and fatigue hysteresis loss energy corresponding to different number of applied cycles have been analyzed. The fatigue hysteresis loops models for different interface slip cases have been derived based on the fatigue damage mechanism of fiber slipping relative to matrix in the interface debonded region upon unloading and subsequent reloading. The fiber/matrix interface shear stress has been estimated for different numbers of applied cycles. By combining the interface shear stress degradation model and fibers strength degradation model with fibers failure model, the tension-tension fatigue life S-N curves of unidirectional C/SiC composite at room temperature and 800 °C under air have been predicted.
