Objective: This study was conducted to investigate basic information on genetic structure and characteristics of Limousin population in Hungary. Obtained results will be taken into consideration when adopting the new breeding strategy by the Association of Hungarian Limousin and Blonde d'Aquitaine Breeders (AHLBB). Methods: Genetic diversity and phylogenetic relationship of 3,443 Limousin cattle from 16 different herds were investigated by performing genotyping using 18 microsatellite markers. Amplified DNA was genotyped using an automated genetic analyzer. Results: Mean of effective alleles (ne) of the populations was 3.77. Population C had the lowest number of effective alleles (3.01) and the lowest inbreeding coefficient (FIS) value (–0.15). Principal component analysis of estimated genetic distance (FST) values (p<0.000) revealed two herds (C and E) distinct from the majority of other Limousin herds. The pairwise FST values of population C compared to the others (0.066 to 0.120) fell into the range of moderate genetic distance: 0.050 to 0.150, while population E displayed also moderate genetic distance (FST values in range 0.052 to 0.064) but only to six populations (G, H, J, L, N, and P). FST(C-E) was 0.148, all other pairs -excluding C and E herds- displayed low genetic distance (FST<0.049). Population D, F, I, J, K, L, N, O, and P carried private alleles, which alleles belonged to 1.1% of the individuals. Most probable number of clusters (K) were 2 and 7 determined by Structure and BAPS software. Conclusion: This study showed useful genetic diversity and phylogenetic relationship data that can be utilized for the development of a new breeding strategy by AHLBB. The results presented could also contribute to the proper selection of animals for further whole genome scan studies of Limousins.

Different methods of axial and tangential testing and various sample geometries were investigated, andnew test geometries were designed to determine the ultimate tensile strength of zirconium claddingtubes. The finite element method was used to model the tensile tests, and the results of the simulationswere evaluated. Axial and tangential tensile tests were performed on as-received and machined fuelcladding tube samples of both E110 and E110G Russian zirconium alloys at room temperature to comparetheir ultimate tensile strengths and the different sample preparation methods

Segmented mandrel tests of as-received and hydrogenated WWER fuel cladding tubes

Kiraly, Marton,Horvath, Marta,Nagy, Richard,Ver, Nora,Hozer, Zoltan Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.9

The mechanical interaction between the fuel pellet and the cladding tube of a nuclear fuel rod is a very important for safety studies as this phenomenon could lead to fuel failure and release of radioactivity. To investigate the ductility of cladding tubes used in WWER type nuclear power plants, several mandrel tests were performed in the Centre for Energy Research (EK). This modified mandrel test was used to model the mechanical interaction between the fuel pellet and the cladding using a segmented tool. The tests were conducted at room temperature and at 300 ℃ with inactive as-received and hydrogenated cladding ring samples. The results show a gradual decrease in ductility as the hydrogen content increases, the ductile-brittle transition was seen above 1500 ppm hydrogen absorbed.

Objectives This study evaluated the efficiency of WaveOne Primary files (Dentsply Sirona) for removing root canal fillings with 2 types of movement: reciprocating (RCP) and continuous counterclockwise rotation (CCR). Materials and Methods Twenty mandibular incisors were prepared with a RCP instrument (25.08) and filled using the Tagger hybrid obturation technique. The teeth were retreated with a WaveOne Primary file and randomly allocated to 2 experimental retreatment groups (n = 10) according to movement type: RCP and CCR. The root canals were emptied of filling material in the first 3 steps of insertion, until reaching the working length. The timing of retreatment and procedure errors were recorded for all samples. The specimens were scanned before and after the retreatment procedure with micro-computed tomography to calculate the percentage and volume (mm3) of the residual filling material. The results were statistically evaluated using paired and independent t-tests, with a significance level set at 5%. Results No significant difference was found in the timing of filling removal between the groups, with a mean of 322 seconds (RCP) and 327 seconds (CCR) (p < 0.05). There were 6 instrument fractures: 1 in a RCP motion file and 5 in continuous rotation files. The volumes of residual filling material were similar (9.94% for RCP and 15.94% for CCR; p > 0.05). Conclusions The WaveOne Primary files used in retreatment performed similarly in both RCP and CCR movements. Neither movement type completely removed the obturation material, but the RCP movement provided greater safety.

A Case Study of the Development of the Shanghai Pudong New Area

Andrew M. Marton,Wei Wu 한국국제상학회 2004 國際商學 Vol.19 No.2

The Pudong New Area (PNA), lying to the east of the Huangpu River in the Shanghai municipal region and covering an area of 556 ㎢, has seen a remarkable transformation since the Chinese government formally announced plans for large scale development here in 1990. In the ten years to 2002, the area experienced average annual GDP growth of above 19 percent reaching above US$ 15 billion in 2002 (pudong New Area Statistics Bureau (PNASB, 2003). Population has grown from 1.34 million to more than 2.47 million over the same period. The Pudong New Area is Shanghai's largest urban district with local financial revenue above US$ 1.1 billion in 2002 (PNASB, 2003). The strategy and design of the PNA and subsequent spatial economic outcomes are large-scale, comprehensive and have been rapidly implemented with a number of relatively distinctive local characteristics not seen elsewhere in China, including a dramatic new CBD skyline. Which brings us to the second characteristic referred to above. The authorities responsible for development in Pudong have sought explicitly to maximize the mutual benefits of links to the older parts of central Shanghai in Puxi and to the wider region, especially the lower Yangzi delta. This is most clearly reflected in the construction of new transportation infrastructure linking Pudong to Puxi. Utilizing an established urban core to support the development of new adjacent areas is not unique to Shanghai. This son of thing has happened elsewhere in China. Notable nearby examples include Suzhou and Kunshan in southern Jiangsu (Cartier, 1995; Manon, 2000). However, the scale of such developments elsewhere, and the implications for spatial economic change and urban transformation, pale in comparison to the depth and extent of changes in the Pudong New Area in relation to Shanghai. While the contours of the spatial economic landscape have been transformed, there have also been other less obvious, but no less significant changes in perceptions of Pudong in relation to the rest of Shanghai (Gamble, 2003). A common refrain among Shanghai residents before 1990 suggested that a single bed in Puxi was preferable to a new house in Pudong. While some locals may still scoff at the prospects of living across the Huangpu River, there is little doubt in the eyes of many Shanghai residents and other observers that Pudong represents the future of a modem, urbane, internationally competitive and cosmopolitan China.

Periphony-Lattice Mixed-Order Ambisonic Scheme for Spherical Microphone Arrays

IEEE 2018 IEEE/ACM transactions on audio, speech, and langua Vol.26 No.5

<P>Most methods for sound field reconstruction and spherical beamforming with spherical microphone arrays are mathematically based on the spherical harmonics expansion. In many cases, this expansion is truncated at a certain order as in higher order ambisonics (HOA). This truncation leads to performance that is independent of the incident direction of the sound waves. On the other hand, mixed-order ambisonic (MOA) schemes that select an appropriate subset of spherical harmonics can improve the performance for horizontal directions at the expense of other directions. This paper proposes an MOA scheme called Periphony-Lattice to improve sound field reconstruction performance for horizontally incident sound waves. The proposed scheme is compared with the previously introduced MOA and HOA schemes in terms of theoretical truncation error and performance in sound field reconstruction and spherical beamforming. Computer simulations and measurements are conducted with a spherical array of 52 microphones with a nonuniform layout. The results show that the proposed MOA scheme has better performance in sound field reconstruction and spherical beamforming for horizontal sound waves than the other schemes for a given number of microphones. This scheme can be applied to other spherical array layouts if the number of microphones is greater than that of the required spherical harmonics coefficients, and may improve the horizontal performance.</P>
