The purpose of this work was the force–displacement response analysis of the masticatory process in a dried human skull by Double-Exposure Photorefractive Holographic Interferometry Technique (2E-PRHI). The load concentration and dissipation of the forces from dried human skull were analysed at applied loading stands as a Simulation of Isolated Contraction (SIC) of some mastication muscles. The 2EHI and Fringe Analysis Method were used to obtain the quantitative results of this force–displacement response. These results document quantitatively the real biomechanical response from dried human skull under applied loading and it can be used for complementary study by finite element model and others analysis type. 相似文献

Brazil is one of the leading exporters of ornamental fishes, mostly freshwater; however, monitoring of the trade is nearly non-existent in the country. This paper provides an initial assessment of a new venture, the marine aquarium fish trade at Ceará State, northeast Brazil, aiming to document the species traded, to provide preliminary estimates of numbers of specimens traded, and to identify priorities in data collection and monitoring. A total of 143 species and 199 304 fishes were traded. From the total, 109 species were native and represented 84% of the fishes traded. Thirty-four exotic species figured on the permits and amounted to nearly 16% of the exports; however, most of them consist of misidentified native species. Nearly 90% of the fish trade was directed to the international market. Official figures represent an underestimation of the total number of captured specimens. 相似文献

Background
Obesity is rapidly becoming a worldwide epidemic that affects children and adults. Some studies have shown a relationship between obesity and infertility, but until now it remains controversial. Thus, the aim of the present study was to investigate the effect of high-fat diet-induced obesity on male reproductive parameters. 相似文献5.
The main causes of numerical chromosomal anomalies, including trisomies, arise from an error in the chromosomal segregation during the meiotic process, named a non-disjunction. One of the most used techniques to analyze chromosomal anomalies nowadays is the polymerase chain reaction (PCR), which counts the number of peaks or alleles in a polymorphic microsatellite locus. It was shown in previous works that the number of peaks has a multinomial distribution whose probabilities depend on the non-disjunction fraction F. In this work, we propose a Bayesian approach for estimating the meiosis I non-disjunction fraction F. in the absence of the parental information. Since samples of trisomic patients are, in general, small, the Bayesian approach can be a good alternative for solving this problem. We consider the sampling/importance resampling technique and the Simpson rule to extract information from the posterior distribution of F. Bayes and maximum likelihood estimators are compared through a Monte Carlo simulation, focusing on the influence of different sample sizes and prior specifications in the estimates. We apply the proposed method to estimate F. for patients with trisomy of chromosome 21 providing a sensitivity analysis for the method. The results obtained show that Bayes estimators are better in almost all situations. 相似文献

Seahorses (Hippocampus spp.) are globally threatened by overexploitation and habitat destruction; they are also regarded as susceptible to heavy
exploitation due to some of their life-history traits. From an economic perspective, they are fishes with high monetary value
and marketability. Seahorses are now listed in Appendix II of CITES (Convention on International Trade in Endangered Species
of Wild Fauna and Flora), to ensure that the international trade is not detrimental to the survival of wild populations; the
effectiveness evaluation of these international controls needs comparable monitoring data, including evaluation of spatial
and temporal trends. This study assesses the seahorse trade in Brazil, aiming to detect trends in catch levels, volumes and
prices. Our main findings were: the dried trade was unregulated, without formal records, and primarily domestic, although
records of unreported exports existed; it was primarily sustained by incidental captures in trawl nets. The live seahorse
trade was mainly destined for exports, and regulated through national quotas. Between 2002 and 2009, mean prices for dried
seahorses ranged from US$1.06 ± 0.46 (level 1 traders) to US$1.06 ± 0.46 (level 1 traders) to US2.78 ± 0.68 (end-sellers) each, while mean prices for each live
seahorse traded on the domestic market (1997–2009) ranged from US$1.13 ± 0.02 (level 1 traders) to US$1.13 ± 0.02 (level 1 traders) to US10.08 ± 1.71 (retailers).
Mean declared export price (2006–2008) was 15.57 ± 10.87. Enhanced implementation of the CITES listing in Brazil will require
further research, and additional measures to address both direct and indirect fishing pressure on seahorse populations. 相似文献
