Gastroesophageal Reflux and Body Movement in Infants: Investigations with Combined Impedance-pH and Synchronized Video Recording

The aim of this paper was to investigate the temporal association of gastroesophageal reflux (GER) and body movement in infants. GER were registered by combined impedance-pH, documentation of body movement was done by video. Videorecording time (Vt) was divided into “resting time” and “movement time” and analyzed for occurrence of GER. Association was defined as movement 1 minute before/after the beginning of a GER. Statistical evaluation was by Fisher's exact test. In 15 infants, 341 GER were documented during Vt (86 hours). 336 GER (99%) were associated with movement, only 5 episodes (1%) occured during resting time. Movement was significantly associated with the occurrence of GER (P < .0001). There is a strong temporal association between GER and body movement in infants. However, a clear distinction between cause and effect could not be made with the chosen study design. Combined impedance-pH has proven to be the ideal technique for this approach

Фторидная технология получения титановых порошков

Обоснована необходимость разработки новой технологии переработки титансодержащих концентратов. Выполнено исследование процесса фторирования рутилового концентрата элементным фтором. Описаны процессы, протекающие при электролитическом получении титановых порошков во фторидных расплавах TiF4. Для отмывки от примесей катодного осадка предложено две технологии – в смеси неорганических кислот и безводным HF; показаны преимущества отмывки HF; содержание примесей в порошке титана, полученном отмывкой в безводном HF несколько ниже, чем при "кислотной" отмывке. При промышленном осуществлении процесса HF рециркулирует в схеме, обеспечивая экологическую безопасность и низкую себестоимость Ti.The brief review of industrial technologies of processing the titanium containing concentrates has been carried out. The research of the fluorination process of rutile concentrates with element fluorine was carried out. The processes occurring during the electrolysis of titanic powders from fluoride fusions, from TiF4, are described. In order to wash off impurities of cathode deposit, two techniques were proposed - in a mixture of inorganic acids and anhydrous HF; advantages of washing off with HF are shown; the impurity content in the titanium powder obtained by washing off in anhydrous HF is slightly lower than at "acid" washing off. In the industrial process implementation HF recycles tin a circuit that ensures environmental safety of production and low production cost of obtained Ti

The problem(atics) of post-colonisation: the subject in settler post-colonial discourse

This thesis concerns aspects of settler post-colonial discourse, examined through fictional and non-fictional prose writing from Australia, Canada and New Zealand. Major works discussed have been published between the 1970s and 1990s. These include fiction by Kate Grenville, Elizabeth Jolley, and Sally Morgan, from Australia; Alice Munro, Audrey Thomas, Aritha Van Herk and Rudy Wiebe, from Canada; and Stevan Eldred-Grigg, Patricia Grace, Keri Hulme, Witi Ihimaera and Ian Wedde, from New Zealand. Section One of the thesis begins with an Introduction which contextualises the following discussion in relation to background issues of definition of the term 'post-colonialism', and then describes the scope, method and selection of texts in the thesis. The argument is briefly stated and expanded upon in discussion of the theoretical perspectives. Chapter One suggests a reading of Empire as (M)Other in relation to Britain's settler colonies, and the status of the latter, within the terms of the familial metaphor, as extensions of Empire. The ambivalence of that status – as extension and as autonomous being -- is explored in consideration of affective relations between colonies and Empire. Also considered are the consequences of this 'familial'-colonial background for the attainment of 'autonomous' Nationhood, imaged as 'self-hood' according to a masculine model of the self. Analysis of discourses of (national) identity reveals 'subjective sovereignty' to be a discursive illusion, disturbed by two sources of 'disunity': 'neo-imperialism' is suggested as an 'external' threat to sovereignty, while post colonialism constitutes the difference within', akin to the functioning of the unconscious in relation to the subject. The chapter concludes with an analysis of subjective processes in three fictional texts. Section Two introduces a focus on how subjectivity is articulated through post-colonial discourses. Chapter Two explores the post-colonial textual mediation of relationships to the land, including the representation of land and landscape in writing, and the resultant facilitation of settler appropriation of the land -- of belonging. It concludes with a reading of post-colonial fictional critiques of colonisation and textuality as the basis of an authentic relationship to the land. Chapter Three considers discourses from indigenous and 'other' subject-positions which, rather than subsuming the land under their own identity, seek to gain and express their identity in relation to the land, attempts at elision of the alienating intervention of textuality. It concludes with discussion of texts which problematise the authority of textuality. Chapters Four and Five more fully examine the subject-positions of 'self' and 'other' in the context of the settler post-colonial ambivalence of authority and authenticity. Chapter Four considers strategies of privileging and appropriating the discursive place of the 'post-colonised' in order to authenticate the authority of the 'post-colonisers'. Chapter Five addresses the 'authorising' of the 'other' into a 'self', or a subject in discourse, and entry into the discursive market as the ambivalent attempt both to accede to subjectivity and to articulate it with the integrity of authenticity. The problems with this invoke the subjective problematic of hybridity which is introduced at the end of Chapter Five. The third section develops the preceding exploration of discourses into a consideration of subjective and discursive problematics, informed by an understanding of post-colonialism as a condition of instability resulting from the re-introduction of what the dominant (National) discourse constitutively excludes. In its phallocentric subjective moment, the exclusion is shown to be that of the maternal body and thus any possibility of a feminine sex; in its imperially-informed cultural moment, it is difference and heterogeneity which are submitted to and subsumed under the colonising gaze: they are disavowed, and the disavowed objects repressed to the 'national' unconscious. Chapter Six posits an analogy between the productions of sexual and colonial difference. Similarly in that chapter the return to, and reconsideration of, motifs and analyses in the thesis enact the thematic-analytic focus on the return of the body and its contaminations of unity, purity and linearity. In Chapter Seven, the theory of the abjection of the subject is employed to suggest a reading of the non-autonomy and non-integrity of settler post-colonial subjectivities and cultures: the settler post-colonial subject is abjected by the internal difference of its own heterogeneity -- the body-difference for which the metaphor of the land (as mother) is used -- and by the perceived radical cultural otherness or externality of post-modernism. However, it is argued that these others are constitutive of the post-colonial self, and that cultural and political agency must therefore relinquish its privileging of purity and sameness, principles which themselves re-play the dynamics of imperialism. Chapter Seven concludes with an argument against the imperialism of identity and against the identity of a text. Chapter Eight concludes the third Section, and the thesis as a whole, with the exploration of a textual-cultural 'case-study' in the discourses and problematics which have constituted the preceding discussions
