Assessment of patients skin dose undergoing coronary angiography and Percutaneous Transluminal Coronary Angioplasty (PTCA)

Background: Practice of interventional cardiology procedures such as Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) has largely increased in recent years and is now changing to a matter of routine in many hospitals. The purpose of this study was to measure skin and organ doses in patients undergoing CA and PTCA and to find a probable relation with cardiologist's work experience. Materials and Methods: A group of 57 patients who were admitted to Nour and Chamran hospitals, Isfahan, Iran, either for CA (n=37) or PTCA (n=20) was checked for skin, eyes and thyroid gland radiation dose. Skin dose measurement was carried out with thermoluminescent dosimeters (TLD-100) placed at three different positions on the patients' bodies. Also the thyroid and eye doses were measured using the same procedure. Results: Mean median, standard deviation and maximum doses for these results are presented. Maximum values found for skin in CA, PTCA, thyroid gland and eyes were 41.00, 73.90, 3.10 and 1.43 cGy, respectively. Average exposure time for CA and PTCA was 4.2±2.6 and 10.8±8.2 minutes, respectively. Radiation dose to the critical areas in each procedure in addition to its relation to the type of procedure was studied. Correlation between maximum skin dose and cardiologists' work experience was also investigated. Conclusion: 85% of the cases in CA and 78% of cases in PTCA received maximum skin dose of lower than 25cGy well below the threshold of 2 Gy suggestions for transient erythema. Iran. J. Radiat.

An agenda for neuroeducation: relating psychophysiological and behavioral data across time scales of learning

Research on learning has previously focused on changes in knowledge and behavior occurring over long periods of time, such as over a period of hours, weeks, months and years. However, there is no doubt that learning-contingent changes in knowledge and behavior are mediated by neural processes occurring at much shorter timeframes (e.g., milliseconds), including the time between a single observable behavioral event, that help determine whether learning occurs. In addition, current applied research in education requires experimentation and assessment in authentic contexts within which learning and performance take place in order to provide ecologically valid results with respect to contemporary contexts that involve social interaction. We argue that it is now time for the field of neuroeducation to relate psychophysiological and behavioral data across time scales. Globally, a better understanding of the underlying cognitive processes occurring during different components of learning. This should lead to novel learning environments, greater and more efficient interactivity between teacher and learner(s), better assessment tools leading to qualitatively and quantitatively better development of knowledge and skills in key domains such as teaching, business, health professions, engineering as well as other domains targeting human development and well-being. Along these lines, this paper presents a research program oriented towards the modeling of learning trajectories and performance at psychophysiological, cognitive and social levels. The projected research findings should allow for more significant understandings of the implication of cognitive neuroscience in education by linking results with more authentic learning and performance situations.
Experimental Investigations of the Spherical Taylor-Couette Flow Using Electrodiffusion Technique

Transition to turbulence of a viscous incompressible fluid flow between two concentric spheres with the inner one rotating and the outer stationary was investigated experimentally. The flow modes were studied using the flow visualization and electrochemical technique. Different flow states were obtained for the gap/radius ratio 0.107 in function of the Taylor number in the interval (22 - 1500) and aspect ratio (17 - 21). Observed states were classified into: Taylor Vortex Flow (TVF), Spiral Mode (SM), Spiral Mode  Wavy Mode (SM+WM), Spiral Wavy Mode (SWM), Wavy Mode (WM) and Chaos. The variations of the flow patterns were reflected by the wall velocity gradient, its fluctuation and spectral analysis. Fast Fourier transform applied on the time series of the wall velocity gradient allowed for the analysis and identification of the fundamental frequencies and their evolutions associated with each flow
Panel Data Models with Unobserved Multiple Time- Varying Effects to Estimate Risk Premium of Corporate Bonds

We use a panel cointegration model with multiple time- varying individual effects to control for the enigmatic missing factors in the credit spread puzzle. Our model specification enables as to capture the unobserved dynamics of the systematic risk premia in the bond market. In order to estimate the dimensionality of the hidden risk factors jointly with the model parameters, we rely on a modified version of the iterated least squares method proposed by Bai, Kao, and Ng (2009). Our result confirms the presence of four common risk components affecting the U.S. corporate bonds during the period between September 2006 and March 2008. However, one single risk factor is sufficient to describe the data for all time periods prior to mid July 2007 when the subprime crisis was detected in the financial market. The dimensionality of the unobserved risk components therefore seems to reflect the degree of difficulty to diversify the individual bond risks.
Architectural and Landscape Risk Factors Associated with Bird–glass Collisions in an Urban Environment

Abstract We studied building characteristics and landscape context to predict risk of migratory birds being killed by colliding with sheet glass on Manhattan Island, New York City, New York, USA. Trained volunteers monitored 73 discrete building facades daily from the Upper East Side to the southern tip of the Island during autumn 2006 and spring 2007 bird migratory periods using a consistent and scientifically valid search protocol. We recorded 475 bird strikes in autumn 2006 and 74 in spring 2007 of which 82 and 85%, respectively, were fatal. Most building and context variables exerted moderate influence on risk of death by colliding with glass. We recommend a suite of building characteristics that building designers can use to reduce risk of collisions by minimizing the proportion of glass to other building materials in new construction. We suggest that reduction of reflective panes may offer increased protection for birds. Several context variables can reduce risk of death at glass by reducing ground cover, including changes in height of vegetation, and eliminating shrubs and trees from areas in front of buildings. We estimated 1.3 bird fatalities per ha per year; this rate extrapolates to ∼34 million annual glass victims in urban areas of North America north of Mexico during the fall and spring migratory periods. Clear and reflective sheet glass poses a universal hazard for birds, specifically for passage migrants in New York City, but also representative and comparable to growing urban areas worldwide.
Ethnoecological Survey of Underutilized Plant Diversity of Hamirpur District, Himachal Pradesh, India: An Edibility Assessment

The present study was conducted to explore diversity and status of underutilized wild edible plants of Hamirpur district, Himachal Pradesh, India. Total 85 plant species of 66 genera belonging to 39 families under various life forms and origins were recorded; in which, 30 species as trees (25 native and 5 exotic), 11 shrubs (6 native and 5 exotic), 28 herbs (10 native and 18 exotic) and remaining 16 were creepers (12 native and 4 exotic). Edibility index (EI) showed 100% score of edibility by two species, while 80% was shown by 11 species, 40% by 3 species and remaining 69 species showed 10 to 30% only. Across family, maximum utilization efficiency (10 score) was found only in 2 families (Apiaceae and Violaceae), while 5 families (Chenopodiaceae, Commelinaceae, Liliaceae, Oxalidaceae and Portulaceae) have shown 8 and one family (Amaranthaceae) exhibited 5.8 score followed by 31 other families. In this study, it was observed that consumption mode of various plant parts were either fresh or cooked. In conclusion, present study may help in alleviating food scarcity, malnutrition and can be employed further as commercial crop plants for the welfare of human in developing countries.
Maturity stages of ovary of a minor carp, Labeo bata (Hamilton-Buchanon, 1822)

Histological studies of the ovary of a carp, Labeo bata demonstrate the annual events of its ovarian function. The month wise studies reveal that oogonial proliferation and recruitment of primary oocytes occur during resting (November-December) and preparatory phase (JanuaryFebruary). Ovarian growth is coincided with the enhancement of temperature and photoperiod from the month of March when oocytes are characterised with the inclusion of yolk vesicles and yolk granules. These oocytes are transformed to yolky mature follicles during maturation phase (April to May) and attain the maximum oocyte diameter during spawning phase (June to August) after germinal vesicle breakdown. Ovary undergoes regression with decline of water temperature during September-October. Hypertrophid granulosa cells take active part in resorption of yolky oocytes. The new oogonia appear only after complete resorption of yolky oocytes. This study shows that photo-thermal conditions are the major regulator of the ovarian function in L. bata.
Migrant Background and Higher Education Participation in Europe: The Effect of the Educational Systems

The main aim of this article is to shed light on the extent to which differences in higher education participation between people with and without a migrant background of low/higher social origin can be explained by two macro-level characteristics of national educational institutions: stratification of the secondary school system and provision of alternative access to higher education. General assumptions are that people with a migrant background of low social origin benefit in low-stratified secondary school systems and in systems that provide alternative access to institutions of higher education more than their native peers in the same social stratum, owing to primary and secondary effects of migrant background. Database is a pooled dataset of the five waves of the European Social Survey. Results of logistic multi-level analyses indicate that a low-stratified secondary school system improves the probability of people with a migrant background/low social origin attaining a higher education degree. On the other hand, a stratified secondary school system reduces their chances regarding this educational stage. The provision of alternative access to an institution of higher education improves their likelihood of becoming higher education graduates.
Technical efficiency and food security of African indigenous vegetable farmers in Kenya

Introduction Kenya is rich in African indigenous vegetables (AIVs) with an estimated 210 known species (Pasquini et al., 2009). These vegetables represent an important source of food for households in Sub-Saharan Africa and have been consumed for many years as supplement to diets (Faber et al., 2010). Furthermore, they are also recognized as an important source of income generation and livelihoods for the rural communities, especially for the women (Weinberger et al., 2011) and are considered to be potential as cash crops in the peri-urban areas. Production and sale of AIVs have been found to increase the likelihood of improving poverty levels in Kenya (Gotor and Irungu, 2010). A large number of AIVs are reported to be rich in micronutrients, antioxidants and have health protecting properties and uses (Yang and Keding, 2009).
Founding Family Ownership and Firm Performance in Consumer Goods Industry: Evidence from Indonesia

This research investigates the significant influence of family ownership on the firm performance in order to provide information to decision maker and other interested parties. The analysis includes comparison between family and non-family firm performance in Indonesia. The samples are taken from 31 consumer goods companies, listed in Indonesian Stock Exchange, ranging from 2005 to 2009. The result describes that non-family firms perform better than family firms and no significant influence between family ownership and firm’s profitability. On the other hand, family ownership has negative contribution to firm market valuation. The study suggests that family firms have less financial performance than that of non-family. Family member within the top position and have major control rights contribute negative influence to firm performance. The evidence raises concerns about possible profit manipulation and weak governance law in Indonesia, and as a result there is an expropriation of wealth to the majority and family related shareholders.
Effects of gender and diet on back fat and loin area ultrasound measurements during the growth and final stage of fattening in Iberian pigs

Abstract. Reared in extensive parcels, 50 castrated or spayed Iberian pigs were fattened with conventional or high-oleic-concentrate diets to evaluate the effect of diet and sex on the measurements of the loin area depth, back fat thickness and its layers during the last 6 months before slaughter at eight time points in two anatomical locations by serial scans. The scan was the factor that had the greatest influence, followed by sex and diet. Back fat thickness at 10th rib level was higher than at 14th rib level. The thickness of the outer, middle and inner layers progressively increased over the study period. Throughout the experimental period, the differences between two successive scans of the M. longissimus area did not differ significantly, obtaining the lowest value at the third scan and the highest at the fifth scan. The ultrasound back fat depth was affected by sex, being greater in females and in animals with a high-oleic diet. Positive significant correlations were observed for measurements assessed. The R2 values for the regression equations to estimate M. longissimus area were lower than the values found for the prediction of fat measurements, and they differed between sex and diet. The relative back fat growth was higher than M. longissimus area, not permitting the establishment of a similar growth pattern for fat and muscle. The sex and diet was taken into account in the predictive models. The subcutaneous adipose layers in Iberian pigs grow at different rates during the last 6 months before slaughter; with the ultrasound serial scan, it is possible to show these changes. The change in diet and the sex affect the adipose tissue development, being more noticeable in the middle layer of back fat at 10th rib level and the inner layer at 14th rib level. However, the sex and the use of an enriched oleic acid diet do not affect to loin development. As the middle layer of back fat shows more growth, this layer could be the best to be included in predictive models. The middle layer of back fat could also be good to be included in predictive models. Back fat thickness at the eighth scan can be predicted with moderate accuracy from corresponding measurements taken 30 days earlier and with less accuracy as the interval between measurements increases.
Tissue composition and allometric growth of tissues from commercial cuts and carcass of Texel lambs slaughtered with different weights

In this study, we evaluated the tissue composition, the ratios between different issues, and the allometric growth of tissues from the commercial cuts neck, shoulder, rib, and leg, and of the carcass of Texel lambs. Thirty uncastrated male lambs born from single calvings were used in this experiment. Lambs were weaned, confined individually, and distributed into five treatments with six replications. Each treatment consisted of a predefined slaughter weight (T23 – initial slaughter, T25, T30, T35, and T40). The proportion of bone decreased linearly in the shoulder, rib, and legs, but remained constant in the neck. The proportion of muscle decreased in the rib, whereas in the other cuts it remained constant. The percentage of fat increased as the slaughter weight of the lambs was increased, for all cuts. In all cuts and in the carcass, bone and muscle showed early growth (b 1). The proportion of bone decreased and fat increased linearly in the carcass, and the proportion of muscle was not influenced by the slaughter weight of the lambs. The muscle/fat ratio decreased in all cuts, and consequently in the half-carcass, as the slaughter weight was increased. The muscle/ bone ratio increased in the shoulder, rib, leg, and half-carcass, but there was no significant effect on the neck. The bone and muscle tissues showed early growth, whereas the fat had late growth in the different commercial cuts and carcass of Texel lambs. The tissue growth pattern of the shoulder may be representative of the allometric growth of the different carcass tissues. An increase in the slaughter weight of Texel lambs leads to a reduction of the muscle/fat ratio, due to the higher deposition of fat in the carcass of these animals.
The Determinants of Repeat Purchase Intention for Luxury Brands among Generation Y Consumers in Malaysia

Repeat purchasing has now become a critical factor for marketers, especially in the luxury goods market. Repeat purchasing not only saves costs (as opposed to attracting new customers), but increases sales as well. Both past and current researchers have been keen in investigating what drives consumers to repeat their purchase. The purpose of this academic research is to examine the relationship between Hedonic Value (HV), Satisfaction (S), Consumer Inertia (CI) and Product Attribute (PA) with the Repeat Purchase Intention (RPI) for luxury brands among Generation Y consumers in Malaysia. As such, eight luxury brands have been selected to investigate the consumer behaviour of consumers in Malaysia, in relation to the repeat purchase intention. This is a quantitative study that collected data from 134 respondents. Findings reveal that Hedonic Value and Satisfaction have positive and significant correlation with Repeat Purchase Intention, with Satisfaction being the strongest predictor of Repeat Purchase Intention. The findings can be used by marketers in Malaysia to aid them in creating marketing strategies to maintain their current customer base, as well as attract new customers to purchase their luxury brands within their target market. This study can also motivate current researchers to further investigate in the field of luxury brands, in an attempt to bridge the gap between luxury brands and Repeat Purchase Intention.
Fires in the dark. Wood and charcoal analysis of the Early Medieval funerary deposits in the cave of Riocueva (Cantabria, Spain)

Abstract: The results of the uncharred wood and charcoal analysis carried out on samples from the site are presented in this work. The assemblages comprised debris from combustion structures, remains related to the funerary burnings and torches, and also fragments of uncharred wood probably related to the funerary rite. The cave of Riocueva was used as a burial place at some point between the 7th and 8th centuries cal. AD. Archaeological work carried out between 2010 and 2014 has recovered the remains of at least eight young individuals and many associated objects: glass beads, rings, spindle hooks, knives and pot sherds, among others. As in other burial caves of similar chronologies from the Cantabrian region, rituals linked to the treatment of corpses have been detected. The destruction and burning of the skulls is the most stunning of them. Furthermore, burning grain beside the bodies, a custom forbidden by medieval penance books, has been tentatively suggested as a possible practice forming part of the rituals. Keywords: Funerary Archaeology, Burned bones, Archaeobotany, Fire, Ritual Resumen: Fuegos en la oscuridad. Analisis xilo-antracologico de los depositos sepulcrales altomedievales de Riocueva (Cantabria, Espana) Los resultados de los analisis xilo-antracologicos llevados a cabo en las muestras de este yacimiento se presentan en este trabajo. Las muestras incluyen restos relacionados con estructuras de combustion, residuos de las quemas funerarias y de las antorchas, asi como fragmentos de madera no quemada asociados probablemente al rito funerario. La cueva de Riocueva fue utilizada como lugar de enterramiento en algun momento durante el periodo comprendido entre los siglos VII y VIII cal. DC. El trabajo arqueologico llevado a cabo entre los anos 2010 y 2014 ha proporcionado los restos de al menos ocho individuos jovenes y muchos objetos asociados a los mismos: cuentas de vidrio, anillos, ganchos de huso, cuchillos y fragmentos ceramicos entre otros. Como sucede en otras cuevas sepulcrales de cronologias similares en Cantabria, se han detectado rituales relacionados con el tratamiento de los cuerpos. La destruccion y quema de los craneos es la mas impresionante de ellas. Ademas, la quema de grano al lado de los cuerpos, una costumbre prohibida en los libros de penitencia medievales, ha sido tambien sugerida como una posible practica.

A link between BIS/BAS, frontal asymmetry and empathy; predispositions towards arousal in affectively charged imagery.

Research into the relationship between Gray’s behavioural activation and inhibition systems (BIS/BAS) and frontal alpha asymmetry have led to conflicting results within the literature. While inter-individual variation in both asymmetry and BIS/BAS manifest as personality traits enveloping both motivation and emotion, a discrepancy exists with relating the BIS with left-favouring asymmetry. Other research has started to find relationships between BIS/BAS and empathy, more specifically how a predisposition to a BIS or BAS predicts empathic arousal towards negative or positive targets. The current experiment aimed to close the gap in the literature regarding BIS/BAS and trait asymmetry, as well as investigate the role empathy (using Basic Empathy Scale in Adults (BES-A)) and BIS/BAS play in arousal to positive a negative imagery, in an attempt to replicate recent finding. Arousal was measured under 4 domains; 2 physiological (EEG, GSR) and 2 self-report (arousal and valance). No significant relationship was found between BIS/BAS and asymmetry. Nor was BIS/BAS a predictor of arousal to affective imagery. High levels of emotional disconnect, a very recent construct implicated in empathy, was found to correlate with reduced perceived empathic arousal to negative imagery. Reduced right sided alpha activity was found to be strongly related with high cognitive and emotional empathy and low emotional disconnection in low BIS individuals. The results suggest that individuals with low trait BIS individuals may generally be more empathic as they experience less anxiety relating to high BIS goal conflict when approached with the choice to empathise.
