Volume calculation of the cattle (Bos taurus L.) and the water buffalo (Bos bubalis L.) metapodia with stereologic method

In this study, stereological volume estimations using 26 cattle metapodia (26 metacarpal and 26 metatarsal bones) and 8 water buffalo metapodia (8 metacarpal and 8 metatarsal bones) were made. For this purpose metapodia were parallel sectioned at 1 cm intervals according to Cavalieri principle. Grids with 0.4 cm probe intervals were superimposed on top of these sections and the matching points were counted. All of the bone structures and medullar cavity volumes were calculated with the data obtained from a formulation (V = t × a(p) × ΣP) as a spreadsheet using Microsoft Excel® Windows XP. In addition, percent ratio of this volume to whole bone volume was calculated. The mean ratio of bone marrow space to whole bone structure volume equals 15% in all of the cattle and buffalos. The difference between whole bone volumes of cattle and water buffalo was significant (p < 0.05) while the difference in volume of medullary cavity (cavum medullare) was not significantly different between the two investigated species. The aim of current study is to present a new method that can be used for the volumes calculation of whole bones and medullary cavity in metapodial bones and their percentages.

Football and the risk-return relationship for a stock market: Borsa Istanbul

We hypothesize that results of football (soccer) teams affect the risk perception of people. People choose riskier investments after a win and less risky investments after a loss; this leads to higher (lower) returns in the stock market. These hypotheses are tested for the international matches of Turkey's three most popular teams (Beşiktaş, Fenerbahçe, and Galatasaray). The empirical findings suggests that the teams' wins led to higher asset returns and lower risk aversion on the following business day of the Borsa Istanbul and lower returns and higher risk aversion after a loss or a tie. © 2013 M.E.

Effects of daylight savings time changes on stock market volatility

The presence of daylight savings time effects on stock returns and on stock volatility was investigated using an EGARCH specification to model the conditional variance. The evidence gathered from the major United States stock markets for the period between 1967 and 2007 did not support the existence of the daylight savings time effect on stock returns or on volatility. Returns on the first business day following daylight savings time changes were not lower nor was the volatility higher, as would be expected if there were an effect. © Psychological Reports 2010

Ancient DNA SNP-panel data suggests stability in bluefin tuna genetic diversity despite centuries of fluctuating catches in the eastern Atlantic and Mediterranean

Atlantic bluefin tuna (Thunnus thynnus; BFT) abundance was depleted in the late 20th and early 21st century due to overfishing. Historical catch records further indicate that the abundance of BFT in the Mediterranean has been fluctuating since at least the 16th century. Here we build upon previous work on ancient DNA of BFT in the Mediterranean by comparing contemporary (2009–2012) specimens with archival (1911–1926) and archaeological (2nd century BCE–15th century CE) specimens that represent population states prior to these two major periods of exploitation, respectively. We successfully genotyped and analysed 259 contemporary and 123 historical (91 archival and 32 archaeological) specimens at 92 SNP loci that were selected for their ability to differentiate contemporary populations or their association with core biological functions. We found no evidence of genetic bottlenecks, inbreeding or population restructuring between temporal sample groups that might explain what has driven catch fluctuations since the 16th century. We also detected a putative adaptive response, involving the cytoskeletal protein synemin which may be related to muscle stress. However, these results require further investigation with more extensive genome-wide data to rule out demographic changes due to overfishing, and other natural and anthropogenic factors, in addition to elucidating the adaptive drivers related to these

Washing treatment impact on print quality of screen printed knitted fabrics

The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics on printed samples as well as structural changes of the textile substrate. The aim of this paper is to determine the influences of washing process and different mesh tread count used for printing on print quality. This will be obtained by using spectrophotometric analysis, and GLCM image processing method for print mottle estimation. The results of this research show that increasing number of washing processes leads to higher color differences reproduction color in comparison to printed materials before washing. It also shows that textile surface texture has a great influence on print mottle as well as that number of washing treatment series can generate variations of solid-tone print uniformity. Keywords: cotton, different thread count, GLCM, spectrophotometric analysis, series of washing process

Paradigmatic or Critical? Resilience as a New Turn in EU Governance for the Neighbourhood

Rising from the margins of EU aid documents, resilience became a centrepiece of the 2016 EU Global Security Strategy, especially in relation to the neighbourhood. While new resilience-thinking may signify another paradigmatic shift in EU modus operandi, the question that emerges is whether it is critical enough to render EU governance a new turn, to make it sustainable? This article argues that in order for resilience-framed governance to become more effective, the EU needs not just engage with ‘the local’ by way of externally enabling their communal capacity. More crucially, the EU needs to understand resilience for what it is – a self-governing project – to allow ‘the local’ an opportunity to grow their own critical infrastructures and collective agency, in their pursuit of ‘good life’. Is the EU ready for this new thinking, and not just rhetorically or even methodologically when creating new instruments and subjectivities? The bigger question is whether the EU is prepared to critically turn the corner of its neoliberal agenda to accommodate emergent collective rationalities of self-governance as a key to make its peace-building project more successful
