Regarding the fattening of younger cattle that the Ministry of Agriculture Forestry and Fisheries (MAFF) recommends in Japan, this study looked at vitamin A control in feed and blood and its effect on performance of production and carcass composition of Wagyu steers. Five sets from 10 Wagyu artificial identical twins were divided to into 2 groups, a restricted group (Test) and a supplied group (Control). The body weight at the finishing time of the Test was significantly lower than that of the Control (p<0.05). The daily gain from 13 to 21 months old, as the animals in the Test were fed the concentrated feed without Vitamin A, was significantly different (p<0.05) between the Test and the Control. The total daily gains for the Test and the Control for the fattening period were 0.82 kg/day and 0.93 kg/day, respectively, which showed a significant difference (p<0.01). Regarding the rib thickness, the Test was thinner than the Control. The Beef Marbling Scores of the Test and Control were 3.60 and 2.80, respectively. The muscle weight of the Test was significantly smaller than that of the Control (p<0.01). However, regarding the ratio to the carcass, the Test was significantly higher than the Control (p<0.05). For the fat weight, the Test was smaller by about 15 kg than the Control (p<0.01). Furthermore, for the fat ratio to the carcass, the Test was significantly lower than the Control (p<0.05). The bone weights of the two groups were approximately the same. Regarding the ratio of bone to carcass, the Test was higher than the Control (p<0.01). For the younger fattening method, the low level vitamin A in the serum had the effect that the muscle ratio to the carcass weight was greater and the fat was less, but the carcass and muscle weight were less.

Age at death estimation has always been a crucial yet challenging part of identification process in forensic field. The use of human skeletons have long been explored using the principle of macro and micro-architecture change in correlation with increasing age. The clavicle is recommended as the best candidate for accurate age estimation because of its accessibility, time to maturation and minimal effect from weight. Our study applies pre-trained convolutional neural network in order to achieve the most accurate and cost effective age estimation model using clavicular bone. The total of 988 clavicles of Thai population with known age and sex were radiographed using Kodak 9000 Extra-oral Imaging System. The radiographs then went through preprocessing protocol which include region of interest selection and quality assessment. Additional samples were generated using generative adversarial network. The total clavicular images used in this study were 3,999 which were then separated into training and test set, and the test set were subsequently categorized into 7 age groups. GoogLeNet was modified at two layers and fine tuned the parameters. The highest validation accuracy was 89.02% but the test set achieved only 30% accuracy. Our results show that the use of medial clavicular radiographs has a potential in the field of age at death estimation, thus, further study is recommended.

The effects of intramuscular fat on the sensory characteristics of M. longissimus dorsi in Japanese Black steers were investigated by a trained analytical panel (average 13.4 panelists). Five sets (10 head) of artificial identical twins were divided into 2 groups, high level of intramuscular fat group (HG) which utilized the fattening method of increasing intramuscular fat and low level of intramuscular fat group (LG) which did not use the above method. Regarding M. longissmus dorsi which was produced for use in the sensory evaluation, crude fat contents of HG and LG was 25.8% and 23.2% respectively (p<0.05). Warner-Bratzler shear force, water holding capacity, cooking loss and fatty acid composition of HG and LG were similar between the two groups. M. Longissimus dorsi taken from HG and LG were tested for their sensory characteristics by a trained panel. HG was given higher points for juiciness than LG (p<0.05). There were no significant differences for tenderness and flavor between the two groups. Overall acceptability which synthesized each of the sensory characteristics of HG and LG were 5.04 and 4.69 points respectively (p = 0.05). These results suggested that juiciness increased with the increase of intramuscular fat, and this raised the overall acceptability of M. longissimus dorsi.

Angiogenesis in Bone Regeneration: Tailored Calcium Release in Hybrid Fibrous Scaffolds

<P>In bone regeneration, silicon-based calcium phosphate glasses (Bioglasses) have been widely used since the 1970s. However, they dissolve very slowly because of their high amount of Si (SiO<SUB>2</SUB> > 45%). Recently, our group has found that calcium ions released by the degradation of glasses in which the job of silicon is done by just 5% of TiO<SUB>2</SUB> are effective angiogenic promoters, because of their stimulation of a cell-membrane calcium sensing receptor (CaSR). Based on this, other focused tests on angiogenesis have found that Bioglasses also have the potential to be angiogenic promoters even with high contents of silicon (80%); however, their slow degradation is still a problem, as the levels of silicon cannot be decreased any lower than 45%. In this work, we propose a new generation of hybrid organically modified glasses, ormoglasses, that enable the levels of silicon to be reduced, therefore speeding up the degradation process. Using electrospinning as a faithful way to mimic the extracellular matrix (ECM), we successfully produced hybrid fibrous mats with three different contents of Si (40, 52, and 70%), and thus three different calcium ion release rates, using an ormoglass–polycaprolactone blend approach. These mats offered a good platform to evaluate different calcium release rates as osteogenic promoters in an in vivo subcutaneous environment. Complementary data were collected to complement Ca<SUP>2+</SUP> release analysis, such as stiffness evaluation by AFM, ζ-potential, morphology evaluation by FESEM, proliferation and differentiation analysis, as well as in vivo subcutaneous implantations. Material and biological characterization suggested that compositions of organic/inorganic hybrid materials with a Si content equivalent to 40%, which were also those that released more calcium, were osteogenic. They also showed a greater ability to form blood vessels. These results suggest that Si-based ormoglasses can be considered an efficient tool for calcium release modulation, which could play a key role in the angiogenic promoting process.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-10/am500885v/production/images/medium/am-2014-00885v_0010.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am500885v'>ACS Electronic Supporting Info</A></P>

<P>A lithium–iodine (Li–I<SUB>2</SUB>) cell using the triiodide/iodide (I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP>) redox couple in an aqueous cathode has superior gravimetric and volumetric energy densities (∼ 330 W h kg<SUP>–1</SUP> and ∼650 W h L<SUP>–1</SUP>, respectively, from saturated I<SUB>2</SUB> in an aqueous cathode) to the reported aqueous Li-ion batteries and aqueous cathode-type batteries, which provides an opportunity to construct cost-effective and high-performance energy storage. To apply this I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP> aqueous cathode for a portable and compact 3.5 V battery, unlike for grid-scale storage as general target of redox flow batteries, we use a three-dimensional and millimeter thick carbon nanotube current collector for the I<SUB>3</SUB><SUP>–</SUP>/I<SUP>–</SUP> redox reaction, which can shorten the diffusion length of the redox couple and provide rapid electron transport. These endeavors allow the Li–I<SUB>2</SUB> battery to enlarge its specific capacity, cycling retention, and maintain a stable potential, thereby demonstrating a promising candidate for an environmentally benign and reusable portable battery.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2014/nalefd.2014.14.issue-2/nl404784d/production/images/medium/nl-2013-04784d_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl404784d'>ACS Electronic Supporting Info</A></P>

E-waste management and resources recovery in France

Vadoudi, Kiyan,Kim, Junbeum,Laratte, Bertrand,Lee, Seung-Jin,Troussier, Nadè,ge SAGE Publications 2015 Waste management & research Vol.33 No.10

<P>There are various issues of concern regarding electronic waste management, such as the toxicity of hazardous materials and the collection, recycling and recovery of useful resources. To understand the fate of electronic waste after collection and recycling, a products and materials flow analysis should be performed. This is a critical need, as material resources are becoming increasingly scarce and recycling may be able to provide secondary sources for new materials in the future. In this study, we investigate electronic waste systems, specifically the resource recovery or recycling aspects, as well as mapping electronic waste flows based on collection data in France. Approximately 1,588,453 t of new electrical and electronic equipment were sold in the French market in 2010. Of this amount, 430,000 t of electronic waste were collected, with the remaining 1,128,444 t remaining in stock. Furthermore, the total recycled amounts were 354,106 t and 11,396 t, respectively. The main electronic waste materials were ferrous metals (37%), plastic (22%), aluminium (12%), copper (11%) and glass (7%). This study will contribute to developing sustainable electronic waste and resource recycling systems in France.</P>

<P>The development of active water oxidation catalysts is critical to achieve high efficiency in overall water splitting. Recently, sub 10 nm-sized monodispersed partially oxidized manganese oxide nanoparticles were shown to exhibit not only superior catalytic performance for oxygen evolution, but also unique electrokinetics, as compared to their bulk counterparts. In the present work, the water oxidizing mechanism of partially oxidized MnO nanoparticles was investigated using integrated in situ spectroscopic and electrokinetic analyses. We successfully demonstrated that, in contrast to previously reported manganese (Mn)-based catalysts, Mn(III) species are stably generated on the, surface of MnO nanoparticles via a proton-coupled electron transfer pathway. Furthermore, we confirmed as to MnO nanoparticles that the one-electron oxidation step from Mn(II) to Mn(III) is no longer the rate-determining step for water oxidation and that Mn(W)=O species are generated as reaction intermediates during catalysis.</P>
