The main goal of this study was to identify the performance parameters and blood profile found among female soccer players. The second aim was to examine if there were any systematic differences between players assigned to different playing positions. Thirty-six players (age: 23.7 ± 3.5 y; weight: 61.9 ± 5.7 kg; height: 165.7± 6.2 cm) underwent a set of laboratory tests (cardiopulmonary exercise test, skinfold measurements, Wingate test, sit-and-reach test, and blood biochemical tests). The following results were verified: maximal oxygen uptake (53±3.9 mL.kg-1.min-1), second ventilatory threshold (11.5 ± 0.8 km.h-1), body fat (14.1 ± 2.9%), Wingate anaerobic test (peak power: 9.5 ± 0.8 w.kg-1; mean power: 7.3 ± 0.4 w.kg-1 and fatigue index: 55.5 ± 4.9%),  flexibility test [sit-and-reach]  (18.1 ± 2.9 cm) and biochemical parameters of blood (Hb:13.9 ± 0.3 g.dL-1; iron: 85.2 ± 12.6 µ.dL-1; calcium: 9.2±0.5 mg.dL-1;  total cholesterol: 204.7 ± 34.7 mg.dL-1; HDL-c: 50.7± 3.6 mg.dL-1; LDL-c: 125.8± 23.3 mg.dL-1; triglycerides: 96.8±18.5 mg.dL-1). In conclusion, the current results indicate that present elite players' physiological characteristics are similar to those previously shown, despite the rapid changes of the female soccer game worldwide. However, data showed that different playing positions had different physiological and anthropometrics differences.  
本研究的主要目的是确定女性足球运动员的表现参数和血液特征。第二个目的是检查分配到不同位置的球员之间是否存在系统性差异。36人(年龄:23.7±3.5岁;重量:61.9±5.7 kg;身高:165.7±6.2 cm)进行了一系列实验室检查(心肺运动试验、皮褶测量、温盖特试验、坐举试验和血液生化试验)。验证了以下结果:最大摄氧量(53±3.9 ml .kg-1 min-1),第二次通气阈值(11.5±0.8 km.h-1),体脂(14.1±2.9%),Wingate无氧试验(峰值功率:9.5±0.8 w.kg-1;平均功率:7.3±0.4 w.k kg-1,疲劳指数:55.5±4.9%),柔韧性试验[坐伸](18.1±2.9 cm)和血液生化指标(Hb:13.9±0.3 g.dL-1;铁:85.2±12.6µ.dL-1;钙:9.2±0.5 mg.dL-1;总胆固醇:204.7±34.7 mg.dL-1;HDL-c: 50.7±3.6 mg.dL-1;LDL-c: 125.8±23.3 mg.dL-1;甘油三酯:96.8±18.5 mg.dL-1)。综上所述,目前的研究结果表明,尽管世界范围内的女子足球运动发生了迅速的变化,但目前优秀运动员的生理特征与之前的研究结果相似。然而,数据显示,不同的比赛位置有不同的生理和人体测量差异。

Business failures in the 1980s, in the United States, have prompted the undergraduate programs of Business Administration, Public Administration, Foreign Trade, Accounting and Auditing, Economics, Finance, Management and Leadership, Human Talent Management, Transportation Management, Business Management, Marketing, International Business and Tourism to strengthen the techniques and processes of education of the future professionals, based on the teaching of social responsibility and ethics.  Hence, the main purpose of this research is to analyze the presence of subjects related to Business Ethics and Corporate Social Responsibility (CSR) at Universities and Polytechnic Schools that are within the National Public and Private classification, and which receive allocations and revenues from the State in Ecuador.  For this purpose, null hypotheses (Ho) and alternative hypotheses (H1) have been proposed, obtaining significant statistical evidence in the analysis of 89 curricula of administrative science programs.  The analysis shows that the offer of the 47 studied subjects of social responsibility, and 75 of ethics does not depend on whether the university is public or private to receive allocations and revenues from the State, but it does depend on the type of program or degree that is being offered. These higher education subjects are important to help, the future professional, remember his or her correct behavior, commitment, and actions in the company, in society, and in the environment.
在美国,20世纪80年代的商业失败促使工商管理、公共管理、外贸、会计与审计、经济学、金融学、管理与领导、人力资源管理、交通管理、商业管理、市场营销、国际商务和旅游等本科专业在社会责任和道德教学的基础上加强对未来专业人员的教育技术和过程。因此,本研究的主要目的是分析厄瓜多尔公立和私立大学和理工学院中与商业道德和企业社会责任(CSR)相关的学科的存在,这些大学和理工学院从国家获得拨款和收入。为此,我们提出了零假设(Ho)和备选假设(H1),并在对89个行政科学专业课程的分析中获得了显著的统计证据。分析表明,提供47个社会责任研究科目和75个道德学科并不取决于大学是公立大学还是私立大学从国家获得拨款和收入,但它确实取决于所提供的课程或学位的类型。这些高等教育课程对于帮助未来的专业人士记住他或她在公司、社会和环境中的正确行为、承诺和行动是很重要的。

As the world is changing and developing with every passing day, the requirements of power are also increasing. There is a shift in utilizing the electrical energy as much as possible and for this reason, many countries have already made policies for completely ruling out the machines which don’t run on electricity. Apart from electricity, there are other forms of energy that can be used to convert that form into a more desirable form. For example, in a plant where the smoke comes out of the chimneys or in a car, the smoke carries a large amount of thermal energy with it. This energy is nothing but a waste and reduction in the efficiency of the systems. If somehow, this energy could be recovered, the efficiency can be increased. Thermoelectric generators serve for this purpose. Thermos electric generators get the heat and using the principle of heat conduction and p and n type materials, the heat can be directly converted into the electricity. There are many materials available in the market for p and n type but in our case, we chose silicon germanium which is also one of the most commonly used. First of all, a single module of thermoelectric generator will be made using p and n type material, as well as using conductive material and some ceramic substance. Then, the entire assembly will be made and this assembly will be exported to Ansys where custom materials will be added and applied on to the geometry. After performing analysis on full model, a comparative study will be presented in which the effect of material of conductive plate on to the voltage difference will be studied
随着世界日新月异的变化和发展,对电力的要求也越来越高。在尽可能多地利用电能方面有一个转变,因此,许多国家已经制定了完全排除不用电运行的机器的政策。除了电之外,还有其他形式的能量可以用来将这种形式转化为更理想的形式。例如,在工厂里,烟雾从烟囱里冒出来,或者在汽车里,烟雾携带着大量的热能。这些能源只不过是浪费和系统效率的降低。如果能以某种方式回收这些能量,就能提高效率。热电发电机就是用于这个目的的。热电发电机获得热量,利用热传导原理和p、n型材料,将热量直接转化为电能。市场上有很多p和n型材料,但在我们的案例中,我们选择了硅锗,这也是最常用的材料之一。首先,将使用p型和n型材料,以及使用导电材料和一些陶瓷物质来制作热电发电机的单个模块。然后,整个组装将被制作,这个组装将被导出到Ansys,在那里将添加定制材料并应用到几何形状上。在对全模型进行分析后,将进行对比研究,研究导电板材料对电压差的影响

Shea butter is the under-consumed vegetable fat and oil. Making shea butter a part of food components in confectionaries would increase its utilization. In this study, the cake was produced by incorporating shea butter as shortening. Shea butter to margarine ratio was 100: 0, 50:50, 40:60, 30:70, and 0:100%, and additional cake samples were produced using flashed shea butter. Standard methods determined the physical and proximate properties of the cake samples, while 25-member panelists did the sensory evaluation. Statistical significance was done at p<0.05. The height, weight, and volume of the cake samples ranged from 3.2 to 3.9 cm, 39 to 50 g, and 625 cm3 to 1026 cm3, respectively. The ranges of moisture, fat, protein, carbohydrate, crude fiber, and the ash content of cakes were 13.7-17.3, 24.3- 30.7, 4.4-8.6, 43-50, 0.10-1.10, and 2.9-3.9%, respectively. The energy value of cake samples in kcal ranged from 440 to 471. There was no significant difference (p>0.05) in the height and volume of the cakes produced from 100% shea butter and 100% margarine. The fat, crude fiber, and ash content increase with the increase in Shea butter substitution. There was no significant difference in the taste and appearance of cake samples from 100%, 70%, 60%, and 50% margarine. Cake samples produced with 60% margarine and 40% shea butter were the most liked by the consumers. Acceptable cakes can be produced by the inclusion of up to 50% shea butter as part of the shortening.
乳木果油是消耗不足的植物脂肪和油。使乳木果油成为糖果食品成分的一部分将提高其利用率。在这项研究中,蛋糕是用乳木果油作为起酥油制成的。乳木果油与人造黄油的比例分别为100:0、50:50、40:60、30:70和0:100%,并用闪光乳木果油制作了额外的蛋糕样品。标准方法确定了蛋糕样品的物理和近似性质,而由25名成员组成的小组进行了感官评估。100%乳木果油和100%人造黄油制作的蛋糕的高度和体积均有统计学意义(p0.05)。脂肪、粗纤维和灰分含量随着乳木果替代量的增加而增加。添加100%、70%、60%和50%人造黄油的蛋糕样品在味道和外观上没有显著差异。含有60%人造黄油和40%乳木果油的蛋糕样品最受消费者喜爱。在起酥油中加入多达50%的乳木果油,就可以制作出合格的蛋糕。

Chillies or red peppers are consumed globally as a spice, condiment, culinary and as folk medicine because of their pungent taste, spicy flavour and therapeutic values. Colour, pungency and capsaicinoids are the potential characteristic attributes for assessing the quality of the dried chilli and are accountable for market price, trade and standardisation of the oleoresins. The present study was designed to prepare crude oleoresins from nineteen varieties of chilli and to enrich carotenoids contents in oleoresin paprika and capsaicinoids extractives in oleoresin capsicum separately for the evaluation and standardisation of colour, pungency and total capsaicinoids content. Crude oleoresins from dried fruits of chilli were prepared using conventional solvent extraction method, which were further enriched for the carotenoid and capsaicinoids extractives by fractionation techniques, and yielded oleoresin paprika and oleoresin capsicum separately. Oleoresins and their derivatives were subjected to analytical estimation of colour values, pungency and capsaicinoids content. The colour content was quantified using a UV Vis Spectrophotometer, whereas pungency was determined using HPLC and quantified as Million Scoville Heat Units. Total capsaicinoids contents were also quantified. The highest extraction yield was found in the variety Teja (S-17) that is 8.82%, whereas enriched versions of oleoresin paprika and oleoresin capsicum were calculated higher in the varieties 273 and Teja (S-17) with the values 6.04 and 2.62%, respectively. The colour value of crude extract was the highest (3085.2 CU) in the variety 5531-IPM, whereas paprika was enriched high in the variety Lolly Chilli (3400.5 CU). The highest pungency (1.59 MSHU) was noted in the variety 5531-HPH. In the case of oleoresin capsicum, the pungency was highly enriched in the two varieties 4884 and Teja (S-17), with the MSHU values 6.11 and 5.5, respectively. Total capsaicinoids contents in the crude oleoresin were found maximum in the variety 5531-HPH (10.60%), whereas after purification (oleoresin capsicum), the maximum capsaicinoids contents were enriched in the varieties 4884 and Teja (S-17) with the values 40.73 and 36.67%, respectively. The outcome of our elaborated studies elucidates that Teja (S-17) 5531-HPH, 5531-IPM and 4884 varieties are better for extractive yield, pungency, and total capsaicinoids content, whereas 5531-IPM and Lolly Chilli varieties are better for colour extraction compared to all other varieties.
辣椒或红辣椒因其辛辣、辛辣的味道和治疗价值,在全球范围内被用作香料、调味品、烹饪和民间药物。颜色、辣度和辣椒素是评估干辣椒质量的潜在特征属性,并对油树脂的市场价格、贸易和标准化负责。本研究以19个品种的辣椒为原料制备粗油树脂,分别富集油树脂辣椒粉中的类胡萝卜素含量和油树脂辣椒粉中的辣椒素提取物,对其颜色、辣度和总辣椒素含量进行评价和标准化。以辣椒干果为原料,采用常规溶剂萃取法制备了粗油树脂,再通过分馏技术进一步富集类胡萝卜素和辣椒素提取物,分别得到了油树脂辣椒粉和油树脂辣椒粉。对油树脂及其衍生物进行了颜色值、辣度和辣椒素含量的分析评估。用紫外可见分光光度计定量颜色含量,用高效液相色谱测定辛辣度,并以百万史高维尔热单位定量。辣椒素总含量也进行了定量测定。Teja (S-17)的萃取率最高,为8.82%,而Teja (S-17)和Teja(273)的萃取率最高,分别为6.04和2.62%。品种5531-IPM粗提物颜色值最高(3085.2 CU),而品种Lolly chili粗提物颜色值最高(3400.5 CU)。品种5531-HPH的辣度最高,为1.59 MSHU。以油树脂辣椒为例,4884和Teja (S-17)两个品种的辣度都非常丰富,MSHU值分别为6.11和5.5。总辣椒素含量以5531-HPH品种最高(10.60%),纯化后辣椒素含量以4884和Teja (S-17)最高,分别为40.73和36.67%。结果表明,Teja (S-17) 5531-HPH、5531-IPM和4884品种在提取量、辣度和总辣椒素含量方面表现较好,而5531-IPM和Lolly辣椒品种在颜色提取方面表现较好。

The cellular level of Reactive Oxygen Species (ROS) is regulated by the interaction of complex antioxidant types of machinery in living systems. These natural antioxidants are well known to curtail the adverse effects of free radicals and withstand oxidative damage in biological entities. Antioxidants prevent the oxidation process that can damage cells in the body. They prevent the living system by scavenging the free radicals interactively and harmoniously and doing this get themselves oxidized instead of cells. When the ROS level rises, the damage becomes cumulative and results in incapacitating

Publishing scientific articles in the digital era 在数字时代发表科学论文
Pub Date : 2020-08-20 DOI: 10.20944/preprints201910.0057.v5
M. Pagliaro
In the digital era in which over 4 billion people regularly access the internet, the conventional process of publishing scientific articles in academic journals following peer review is undergoing profound changes. Following physics and mathematics scholars who started to publish their work on the freely accessible arXiv server in the early 1990s, researchers of all disciplines increasingly publish scientific articles in the form of freely accessible and fully citeable preprints before or in parallel to conventional submission to academic journals for peer review. The full transition to open science, I argue in this study, requires to expand the education of students and young researchers to include scholarly communication in the digital era.
在40多亿人经常上网的数字时代,在学术期刊上发表科学文章经过同行评议的传统流程正在发生深刻变化。20世纪90年代初,物理学和数学学者开始在免费访问的arXiv服务器上发表他们的研究成果,之后,所有学科的研究人员越来越多地以免费访问和完全可引用的预印本的形式发表科学文章,在传统的学术期刊上提交同行评审之前或并行。我在本研究中认为,要全面过渡到开放科学,需要扩大对学生和年轻研究人员的教育,将数字时代的学术交流纳入其中。

Self-construal priming reconsidered: Comparing effects of two commonly used primes in the UK and China 反思自我构念启动:两种常用启动效应在英国和中国的比较
Pub Date : 2020-07-02 DOI: 10.23954/osj.v5i3.2418
Shengyu Yang, V. Vignoles
Self-construal priming was devised to mimic the effects of chronic cross-cultural differences. Primes designed to activate independent/interdependent self-construals have been found to affect numerous culturally relevant outcomes. However, researchers have rarely checked precisely what these primes activated, nor tested their cross-cultural equivalence. We compared two common priming tasks, Similarities vs. Differences with Family and Friends (SDFF) and Sumerian Warrior Story (SWS), across seven dimensions of independence/interdependence among 118 British and 178 Chinese participants. The two tasks activated different combinations of self-construal dimensions. SWS showed a similar pattern of effects across cultures, whereas SDFF more strongly affected Chinese participants. Neither manipulation closely mimicked the pattern of pre-existing cross-cultural differences between samples. We propose researchers should develop more precisely targeted self-construal primes.
自我解释启动被设计用来模拟长期跨文化差异的影响。设计用于激活独立/相互依赖的自我构建的启动词已经被发现会影响许多与文化相关的结果。然而,研究人员很少精确地检查这些启动物激活了什么,也没有测试它们的跨文化对等性。我们比较了两种常见的启动任务,与家人和朋友的相似性与差异(SDFF)和苏美尔勇士故事(SWS),在独立/相互依赖的七个维度上对118名英国和178名中国参与者进行了比较。这两个任务激活了不同的自我构念维度组合。SWS在不同文化中表现出相似的影响模式,而SDFF对中国参与者的影响更强烈。这两种操作都没有很好地模仿样本之间存在的跨文化差异。我们建议研究人员应该开发更精确的目标自我解释启动。
