This work presents a short and very efficient method to produce high performance textured Ca_3Co_4O_9 thermoelectric materials through initial powders modification. Microstructure has shown good grain orientation, and low porosity while slightly lower grain sizes were obtained in samples prepared from attrition milled powders. All samples show the high density of around 96% of the theoretical *** similar characteristics are reflected in, approximately,the same electrical resistivity and Seebeck coefficient values for both types of samples. However, in spite of similar power factor(PF) at low temperatures, it is slightly higher at high temperature for the attrition milled samples. On the other hand, the processing time reduction(from 38 to 2 h) when using attrition milled precursors, leads to lower mechanical properties in these samples. All these data clearly point out to the similar characteristics of both kinds of samples, with a drastic processing time decrease when using attrition milled precursors, which is of the main economic importance when considering their industrial production.

Purpose: This study aims to compare adolescents' cardiometabolic risk score through an integrative classification of physical activity(PA),which involves the combination of moderate-to-vigorous physical activity(MVPA) and sedentary behavior(SB).Methods: A cross-sectional study derived from the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study database(2006-2008) was conducted in adolescents(n = 548; boys, 47.3%; 14.7 ± 1.2 years) from 10 European cities. MVPA and SB were objectively measured using accelerometry. Adolescents were divided into 4 categories according to MVPA(meeting or not meeting the international recommendations) and the median of SB time(above or below sex-and age-specific median) as follows: High-SB & Inactive, Low-SB & Inactive,High-SB & Active, and Low-SB & Active. A clustered cardiometabolic risk score was computed using the homeostatic model assessment, systolic blood pressure, triglycerides, total cholesterol/high-density lipoprotein cholesterol, sum 4 skinfolds, and cardiorespiratory fitness(CRF).Analyses of covariance were performed to discern differences on cardiometabolic risk scores among PA categories and each health ***: The cardiometabolic risk score was lower in adolescents meeting the MVPA recommendation and with less time spent in SB in comparison to the high-SB & Inactive group(p < 0.05). However, no difference in cardiometabolic risk score was established between High-SB or Low-SB groups in inactive adolescents. It is important to note that CRF was the only variable that showed a significant modification(higher)when children were compared from the category of physically inactive with "active" but not from high-to ***: Being physically active is the most significant and protective outcome in adolescents to reduce cardiometabolic risk. Lower SB does not exhibit a significant and extra beneficial difference.

El Soplao outcrop, an Early Cretaceous amber deposit recently discovered in northern Spain （Cantabria）, has been shown to be the largest site of amber with arthropod inclusions that has been found in Spain so far. Relevant data provided herein for biogeochemistry of the amber, palynology, taphonomy and arthropod bioinclusions complement those previously published. This set of data suggests at least two botanical sources for the amber of El Soplao deposit. The first （type A amber） strongly supports a source related to Cheirolepidiaceae, and the second （type B amber） shows non-specific conifer biomarkers. Comparison of molecular composition of type A amber with Frenelopsis leaves （Cheirolepidiaceae） strongly suggests a biochemical affinity and a common botanical origin. A preliminary palynological study indicates a regional high taxonomical diversity, mainly of pteridophyte spores and gymnosperm pollen grains. According to the preliminary palynological data, the region was inhabited by conifer forests adapted to a dry season under a subtropical climate. The abundant charcoalified wood associated with the amber in the same beds is evidence of paleofires that most likely promoted both the resin production and an intensive erosion of the litter, and subsequent great accumulation of amber plus plant cuticles. In addition, for the first time in the fossil record, charcoalified plant fibers as bioinclnsions in amber are reported. Other relevant taphonomic data are the exceptional presence of serpulids and bryozoans on the surfaces of some amber pieces indicating both a long exposure on marine or brackish-water and a mixed assemblage of amber. Lastly, new findings of insect bioiuclusions, some of them uncommon in the fossil record or showing remarkable adaptations, are reported. In conclusion, a documented scenario for the origin of the El Soplao amber outcrop is provided.

人工受精(AI)的结果是降低已经进行过高度选择雄性繁殖力评价的奶牛种群数量。1990-2007年采集502头荷斯坦公牛的42348个精液数据进行贝叶斯框架分析,对过去十几年在人工受精中心常规收集的精液进行精液特征进化和遗传参数的评估。主要考虑的特性是精子数量(VOL)、浓度(CONC)、每次射精的精子数量(NESPZ)、总体精子活力(MM)、个体精子活力(IM)以及解冻后活力(PTM)。研究环境因素随时间的变化时,根据环境和技术条件的改变,年龄的变化、射精顺序、提前收集的时间点(TPC)以及收集和冻结期间的时间点(TCF)对其进行每季度和每周的收集,公牛近交系数(Fi)、永久环境和添加剂遗传因素也被考虑在内,运用贝叶斯因子对此降低模型的使用进行评价。在该模型中对所有的系统效应进行测试并除了Fi影响精子活性和TCF影响PTM之外,得出有力的数据证明模型的正确性。观察中发现除PTM外,环境影响没有系统时间的趋势,这表明环境改变的趋势参与精子冻融的改善。遗传力评价除IM外均处于中度(0.16-0.22),其中存在一个低值(0.07)。精子之间活力的相互作用以及精子活力与CONC之间的相互作用存在较大的遗传相关性(0.38-0.87),VOL与CONC显示出负相关性(-0.13)。如果要求使用这些特征作为判断公牛育种精子活力的指标,需要增大遗传性能有效的选择。
