Hormones are an integral part of milk and throughout lactation, the content of certain hormones is unstable. Hormones regulate the process of starting lactation of animals, the lactation process itself, and also the other functions of the body. Milk is of great importance for the growth of young animals and the formation of immunity. Milk is a special product in the diet and is an important food and raw material for the production of dairy products for people. It contains a large amount of protein, fat, carbohydrates, vitamins and trace elements in biologically available form. But at the same time, over the past few years, more and more evidence has emerged that hormones in dairy products can impact on human health. Thus, some estrogens and insulin-like growth factor IGF-1 are involved in the initiation and provocation of breast, prostate and endometrial tumors. That’s why, it is necessary to normalize and control the content of certain hormones in milk with highly sensitive methods.

In recent discussions of the origins and process of animal domestication (Reed, 1961, Zeuner, 1963), both authors rely on two kinds of evidence: on the one hand, the present distributions and characteristics of the different breeds of whatever animal is being discussed, together with its feral and wild relatives, and, on the other hand, the past record, given by literary and pictorial sources and the bones from archaeological and geological sites. Increased recognition of the limitations of the past record, whether in the accuracy of the information it appears to give (as in the case of pictorial sources), or in the certainty of the deductions we are at present capable of drawing from it (this applies especially to the osteological record), has led these authors to argue mainly from the present situation, using the past record to confirm or amplify the existing picture.Arguing from the present, many hypotheses about the origins and process of domestication are available. The only test we have, when attempting to choose between these, lies in the direct evidence of the past record. The past record, it is freely admitted, is very fragmentary: the information provided by the present situation is more exact, ranges over a much wider field, and is more open to test and control. Nevertheless, the past record, however imperfect it is, is the only direct evidence we have about the process of domestication.

The 'scholarly striptease', particularly as it is manifested in the United States, has attracted an increasing number of participants during the past decade. Unbeknownst to many, some academics have been getting their gear off in public; that is, publicly and provocatively showcasing their identities in order to promote their politics. While you might imagine that confessions about sexual orientation, ethnicity and pet hates could only serve to undermine academic authority, some American feminists -- and a small number of their male colleagues -- have nevertheless attempted to enhance their authority with such racy revelations. Nancy Miller's admission of a strained relationship with her father (Miller 143-147), or Jane Gallop's homage to the three 36-year-old men she had affairs with (Gallop 41), might make interesting reading for the academic voyeur (or the psychoanalyst), but what is their purpose beyond spectacle? The cynic might argue that self-promotion and intellectual celebrity or notoriety are the motivators -- and certainly he or she would have a point -- but within such performances of identity, and the metacriticism that clings to them, other reasons are cited. Apparently it is all to do with identity politics, that is, the use of your personal experience as the basis of your political stance. But while experience and the personal (remember "the personal is the political"?) have been important categories in feminist writing, the identity of the intellectual in academic discourse has traditionally been masked by a requisite objectivity. In a very real sense the foregrounding of academic identity by American feminists and those other brave souls who see fit to expose themselves, is a rejection of objectivity as the basis of intellectual authority. In the past, and also contemporaneously, intellectuals have gained and retained authority by subsuming their identity and their biases, and assuming an "objective" position. This new bid for authority, on the other hand, is based on a revelation of identity and biases. An example is Adrienne Rich's confession: "I have been for ten years a very public and visible lesbian. I have been identified as a lesbian in print both by myself and others" (Rich 199). This admission, which is not without risk, reveals possible biases and blindspots, but also allows Rich to speak with an authority which is grounded in experience of, and knowledge about lesbianism. Beyond the epistemological rejection of objectivity there appear to be other reasons for exposing one's "I", and its particular foibles, in scholarly writing. Some of these reasons may be considered a little more altruistic than others. For example, some intellectuals have used this practice, also known as "the personal mode", in a radical attempt to mark their culturally or critically marginal subjectivities. By straddling their vantage points within the marginalised subjectivity with which they identify, and their position in academia, these people can make visible the inequities they, and others like them, experience. Such performances are instances of both identity politics at work and the intellectual as activist. On the other hand, while this politically motivated use of "the personal mode" clearly has merit, cultural critics such as Elspeth Probyn have reminded us that in some cases the risks entailed by self-exposition are minimal (141), and that the discursive striptease is often little more than a vehicle for self-promotion. Certainly there is something of the tabloid in some of this writing, and even a tentative linking of the concepts of "academic" and "celebrity" -- Camille Paglia being the obvious example. While Paglia is among the few academics who are public celebrities, there are plenty of intellectuals who are famous within the academic community. It is often these people who can expose aspects of their identity without risking tenure, and it is often these same individuals who choose to confess what they had for breakfast, rather than their links with or concerns for something like a minority. For some, the advent of "the personal mode" particularly when it appears to contain a bid for academic or public fame signifies the denigration of academic discourse, its slow decline into journalistic gossip and ruin. For others, it is a truly political act allowing the participant to combine their roles as intellectual and activist. For me, it is a critical practice that fascinates and demands consideration in all its incarnations: as a bid for a new basis for academic authority, as a political act, and as a vehicle for self-promotion and fame.

Objective This study is to investigate the changes of trace elements (Cu, Fe, Zn, Se, Mg) in serum and skeletal muscle of rats after skeletal muscle injury induced by downhill running, and to find out the change regularity of trace elements in the body after exercise injury. To provide experimental basis for how to use trace elements supplements reasonably. Methods Fifty-four healthy male Sprague-Dawley rats aged 8 weeks were randomly divided into two groups: control group (C, N=6) and exercise group (E, N=48, include: 0 h group, 6 h group, 12 h group, 24 h group, 48 h group, 72 h group, 1- week group and 2- week group). The rats in exercise groups run down a 16°incline at 16m/min for 90 minutes. At the end of the exercise, the rats were killed at 0 h, 6 h, 12 h, 24 h, 48 h, 72 h, 1 week and 2 weeks, respectively. The serum was got from the inferior vena cava blood and diluted by 1% nitric acid. The muscle was got from the right side of the rat's sural which were digested by concentrated nitric acid and 30% hydrogen peroxide in 75℃water bath for 20mins. The content of trace elements in muscle and serum were measured by inductively coupled plasma atomic emission spectrometry (ICP-MS). All the data are analyzed and processed by SPSS22.0 statistical software. Results (1) The contents of trace elements in serum showed: Cu, Zn, Mg, Se decreased immediately after exercise, but the Cu still increased to reach a peak at 24h after decreasing, and after 2 weeks the content of Cu was slightly lower than pre-exercise level. However, the content of Zn did not elevate again, it continued declined to the lowest at 24h which was significantly lower than control group (P < 0.05). And after 2 weeks, Zn did not return to the pre-exercise level. The changes of Mg, Se in serum was not statistically significant. There is no difference between 0h and control groups in content of Fe, after that Fe decreased continually and appeared the least value at 24h, the differences between immediate group and control group were statistically significant (P < 0.05). Fe returned to the pre-exercise level after 2 weeks. (2) The contents of trace elements in muscle showed: Most of trace elements increased to the maximum level at 6 h, after that Mg, Fe, Cu decreased to the lowest value at 72 h which were significant lower than 0h group or 6h group (P < 0. 05). ALL the trace elements were lower than pre-exercise level. There was no statistical difference in the content of Se in muscle. Conclusions (1) The different changes of trace elements in skeletal muscle and serum after exercise injury may be due to the redistribution of trace elements caused by the body adaptability. (2) The most obviously changes of trace element in serum and muscle are Cu and Zn. Both of them did not return to the pre-exercise level after 2 weeks, it suggests that the supplement include Cu and Zn may play an important role in recovering after exercise-induced injury.

The figure and story of Faustus is part of the European cultural heritage, and as it usually, even inevitably happens with legends, it lives further in the adaptations of later periods and authors . It is mainly linked to Goethe’s name, his figure became well known and immortal in his works. Ever since Goethe, all authors – who respect themselves – in German literature must write a new Faustus, while in other nation’s literatures newer and newer paraphrases were born, which on their turn gave rise to further adaptations, and the scientific, aesthetic etc. literature also has gotten richer. However the canonized, more precisely, classicisized framework of interpretation is not transgressed by any of the newer writers and poets of the past centuries, moreover it is only the form of the legend that is rewritten – naturally with the aim of modernization. All of that as part of the literary heritage. As far as the problem of original sources is concerned: what can be regarded as a source and what is adaptation, which are the works that motivated writers, are just a matter of the preliminary work of the interpretation. On the other hand the problem that within the ancient, mythical tradition there is an original, ancient Faustus legend, does not raise any attention as that is “mere raw material”. The truth is ... that the beginning that has been preliminarily, yet directly definitory for centuries, is that original force that is given in the topic and thus it is difficult to bring it to the surface, preferably independently from the heritage that was built upon it. As far as the time dimension is concerned, we are searching in an undefineable, open past, moreover it is most probable that the legend itself is not entirely original, so to say, but it is the adaptation of a more ancient idea or topic. And by this its symbolism and hidden semantics lose their European characteristics.

Abstract In the past decade, physiological roles and molecular functions of GPRC5 family receptors, originally identified as retinoic acid-induced gene products, have been uncovered, even though their intrinsic agonists are still a mystery. They are differentially distributed in certain tissues and cells in the body suggesting that cell-type-specific regulations and functions are significant. Molecular biological approaches and knockout mouse studies reveal that GPRC5 family proteins have pivotal roles in cancer progression and control of metabolic homeostasis pathways. Remarkably, GPRC5B-mediated tyrosine-phosphorylation signalling cascades play a critical role in development of obesity and insulin resistance through dynamic sphingolipid metabolism.

<p>Dualists view the mind and the body as two fundamental different “things”, equally real and independent of each other. Cartesian thought, or substance dualism, maintains that the mind and body are two different substances, the non-physical and the physical, and a causal relationship is assumed to exist between them. Physicalism, on the other hand, is the idea that everything that exists is either physical or totally dependent of and determined by physical items. Hence, all mental states are fundamentally physical states. In the current study we investigated to what degree Swedish university students’ beliefs in mind-body dualism is explained by the importance they attach to personal values. A self-report inventory was used to measure their beliefs and values. Students who held stronger dualistic beliefs attach less importance to the power value (i.e., the effort to achieve social status, prestige, and control or dominance over people and resources). This finding shows that the strength in laypeople’s beliefs in dualism is partially explained by the importance they attach to personal values.</p>

Regulation as a legal form of social engineering has been subjected to much analysis in the last decade or so. The importance of the topic to contemporary law cannot be overstated: on the one hand, it has been the avowed aim of government to ‘deregulate’ industry; on the other hand, and paradoxically, both the concomitant policy of privatisation and the evolution towards a Single European Market have increased the need for regulation in appropriate areas. The efforts to explore the strengths and weaknesses of different regulatory forms have brought together scholars from a wide range of disciplines. Administrative lawyers have been concerned with how the power of decision-making is allocated between institutions and the general problems of accountability and control of discretion to which this gives rise. Socio-legal researchers have critically examined the practices of regulatory agencies as regards rule formulation and enforcement.

Статья посвящена новым, дополнительным критериям выделения посуды одного мастера. Экспериментально было доказано, что тулово сосуда - наиболее устойчивая его часть. А из его параметров наиболее устойчивым оказался максимальный диаметр. Используя два параметра тулова: его общую пропорциональность и максимальный диаметр, автор выделил из всей посуды Волосово-Даниловского могильника посуду, сделанную по одной и той же форме-модели. Сопоставление сосудов, сделанных по одной форме-модели, с одинаковыми исходным сырьем, составом формовочной массы сосудов и составом шамота в ней позволило выделить посуду одного мастера. Таким образом, предложен еще один критерий для выделения посуды одного мастера: близкие формы-модели, с помощью которых лепились сосуды. Разработанная автором методика выделения посуды гончаров-левшей, с одной стороны, подтвердила правильность методики анализа форм сосудов, а с другой - позволила выявить большее число разных гончаров, посуда которых сопровождала погребенных в могильнике индивидов. The paper is dedicated to new, additional criteria for singling out vessels made by one craftsman. It has been proven experimentally that the vessel body is the most stable element. Regarding its characteristics, the maximum diameter turned out to be the most stable. Using two characteristics of the body, i.e. its proportions and its maximum diameter, the author selected vessels made with the use of the same model shape among all vessels coming from the Volosovo-Danilovo burial ground. Comparison of the vessels made with the use of the same model shape, the same raw material, the same composition of clay paste and proportion of grog in it provided an opportunity to single out vessels made by one craftsman. Therefore, one more criterion for singling out vessels made by the same craftsman is proposed, i.e. a similar model shape used in making vessels. The methodology for identifying left-handed potters developed by the author, on the one hand, confirmed that the methodology of analyzing vessels shape was correct and, on the other hand, made it possible to identify a greater number of various potters whose vessels were placed into the graves as funerary offerings.

Modern core scanning technologies, such as hyperspectral CoreScan™ or X-ray fluorescence (XRF) Itrax, which allow data acquisition without the necessity of breaking the core for speciality analysis, are receiving increasing interest in coal and CSG industries in the past few years. Such technologies are able to characterise and evaluate mineral matter in greater detail than conventional sampling and analyses, producing mineral maps and mineral/elemental profiles throughout the core. Although mineralogical information is the main output from both techniques, CoreScan™ has the ability of producing organic profiles that allow the recognition of the different lithotypes in the coal based on the spectral reflectance as well as rank, which makes a potential technique for coal quality. On the other hand, XRF Itrax core scanner allies the chemical elemental profile, from major to trace elements, with an X-radiographic image, creating a dynamic duo between stony partings and coal, and within the coal between bright and dull lithotypes, through contrasting image properties. These emerging technologies will allow coal reservoirs to be analysed quickly and reliably without subsampling that could introduce bias from the user.

This paper elucidates two positions (the positivist and the critical) that inform the creative design of technological fashion. On the one side is the instrumentalist trend toward the minimized or disappearing interface. On the other, some theorists and artists suggest that increased invisibility presents social and ethical concerns (such as invasiveness and control) when networking and communication devices are involved. The positivist side has roots in modernist design. Positivist designers create responsive and controllable fabrics using shape-changing polymers, e-textiles, and nano-scale electronics to resolve clumsy and prohibitive problems of hardware vs. body. The critical side draws upon archetypal ideas about technology and the body that are familiar from literature and science fiction, and includes writers and media artists who emphasize the intractable or mechanic nature of technological clothing to enhance, rather than erase, the body. The paper concludes that both positions must be considered as the field of technological fashion moves forward.
