Full textAbstract:
The paper deals with the influence of the pulse length on the decay of the sound field energy. Six pulse lengths— 2000, 2500, 3000, 3500, 4000 and 4500 ms—were selected for investigations. Investigations show that a 2500 ms pulse is too short to correctly assess the background noise time interval. Such pulse length is not suitable for experiments. 3000 ms is the right length, while 3500 ms may be too long, resulting in errors of measurement results. When the pulse length increases to 4000 ms, the decay starting from 2000 ms is different from the pulse length 2500 ms and 3000 ms. Background noise starts from 2300 ms for these pulses, while for a 4000 ms pulse it starts from 3200 to 3300 ms. The length of 4500 ms is completely not suitable for investigations because the background noise zone starts very early, ie at 1800 ms, while for a short 2500 ms pulse it starts much later, after 2300 ms. While investigating energy decay, it is important to determine the maximum decay. At 63 Hz the sound field decay is almost uniform till— 18 dB. Later the decay character is different. The decay of the longest (4500 ms) and the shortest (2500 ms) pulse after— 18 dB is very steep and reaches—30 dB. However, the decay is influenced by the background noise. Thus the shortest and the longest pulses are not suitable for the lowest frequencies. The greatest energy decay is characteristic of the 3000 ms pulse. After 1700 ms energy decreases to—30 dB. Thus at this frequency one may measure the echoing time while approximating decay from 0 to—20 dB. As the frequency increases, the results change. At 100 Hz the energy decays by— 35–37 dB at pulse lengths of 2500 ms and 4000 ms. The greatest decay of— 42 dB is produced by the longest pulse 4500 ms though this arouses certain doubts. Then the echoing time may be measured from 0 to— 30 dB. At 125 octave frequency the smallest maximum decay of— 40 dB is observed with the shortest pulse (2500 ms), while the largest one— 50 dB is produced by the longest pulse (4500 ms). Thus standard echoing time may be measured for this frequency. In the frequency range of 250–2000 Hz, the maximum energy decay is sufficient and amounts to— 50–60 dB. At 4000 Hz the final part of decay is strongly dependent on the pulse length although, as the decay is about— 55 dB in all cases, the standard echoing time may be measured correctly. Pulse length is important only for the calculation of the low-frequency echoing time. At 63–100 Hz the best maximum decay is seen with the pulse 3000 ms long, while at 125 Hz and over the best pulse lengths are from 3000 to 4000 ms. When the hall contains audience and tapestries are on the walls, the energy decay is almost uniform at the pulse lengths of 2000 to 2800 ms. In this case a better decay is obtained with the longest pulse of 2800 ms.

AbstractBackgroundThe amino acids glutamine plus glutamate, phenylalanine and tyrosine are implicated in neurotransmission. We aimed to evaluate these amino acid blood concentrations in full-term breastfed infants with different birth weight (BW) perinatally.MethodsBreastfed full-term infants (n = 6000, males 3000, females 3000) BW 2000–4000 g were divided into four equal groups. Both males and females Groups A, 2000–2500 g, B 2500–3000 g, C 3000–3500 g, D 3500–4000 g. Blood samples on Guthrie cards, were taken on the 3rd day of life and quantified via a liquid chromatography tandem mass spectrometry (LC-MS/MS) method.ResultsGlutamine plus glutamate mean values were found to be statistically significantly different between males vs. females in all the studied groups. The highest values were determined in both males and females in group D. Statistically significantly higher values of phenylalanine appeared in group D vs. other groups. Tyrosine mean values were calculated to be statistically significantly different in both sexes in group A compared to other groups.ConclusionsDifferences of glutamine plus glutamate, phenylalanine and tyrosine levels among full-term newborns with different BW are presented for the first time in the literature. Newborns with BW 3000–4000 g are benefited by having higher concentrations of the mentioned neurotransmission related amino acids. Neonatal screening reference values for these amino acids in relation to BW could be established, not only for preterm and low BW infants but also for full-term newborns with BW >3000 g.

Full textAbstract:
The influence of a wide range of CO2 levels on the growth, morphogenesis, and secondary metabolite production in vitro was evaluated. Shoots of thyme (Thymus vulgaris L.) and a spearmint–peppermint cross (Mentha spicata × Mentha piperita) were grown on MS medium with and without 3% sucrose under 350, 1500, 3000, 10,000, and 30,000 μL CO2/L for 8 weeks. Dichloromethane extracts from leafs were analyzed using GC-MS techniques. Prominent peaks were identified by comparison with known standards. Highest growth (i.e., fresh weight) and morphogenesis responses (i.e., leafs, shoots and roots) were obtained when shoots were grown under 10,000 μL CO2/L regardless of whether or not sucrose was included in the medium. Ultra-high CO2 concentrations (3000 μL CO2/L) stimulated secondary metabolite production regardless of whether or not the medium contained sucrose. However, the combination of certain ultra-high CO2 levels (e.g., 3000 to 10,000 μL CO2/L) and the presence of sucrose in the medium resulted in shoots producing the highest levels of secondary metabolites. These results suggest that in vitro photosynthesis, which is stimulated by ultrahigh CO2 levels, may enhance secondary metabolite production.

Full textAbstract:
An analytical method based on protein precipitation has been developed and validated for analysis of lumefantrine in human plasma. Artesunate was used as an internal standard for lumefantrine. Inertsil ODS column provided chromatographic separation of analytes followed by detection with mass spectrometry. The method involves simple isocratic chromatographic condition and mass spectrometric detection in the positive ionization mode using an API-3000 system. The total run time was 2.5 minutes. The proposed method has been validated with linear range of 200–20000 ng/mL for lumefantrine. The intrarun and interrun precision values are within 6.66% and 5.56%, respectively, for lumefantrine at the lower limit of quantification level. The overall recovery for lumefantrine and artesunate was 93.16% and 91.05%, respectively. This validated method was used successfully for analysis of plasma samples from a bioequivalence study.

Full textAbstract:
In conscious dogs methysergide (MS) caused constriction of the saphenous vein at about 3000 times lower doses than methylergometrine (MT) when infused locally, but it elicited only a short-lasting venoconstrictor response when injected systemically intravenously. MS and MT proved to be equally active venoconstrictor agents when administered orally. Analysis of canine plasma by high-performance liquid chromatography showed that after both oral and intravenous administration of MS large amounts of MT appeared in the plasma whereas only low and transient levels of MS could be detected. It is suggested that one of the first steps in metabolism of MS is demethylation at position 1 of the indole, leading to the formation of MT, which may be a main active principle of the therapeutic effectiveness of MS in the interval treatment of migraine headache.

Full textAbstract:
Einen Einblick in die Genealogie der Hausfrau gewährt ein Ratgeber aus der Spätaufklärung, der sich als erste deutsche Ökonomik ausschließlich an Frauen richtet: Die Hausmutter in allen ihren Geschäfften von Christian Friedrich Germershausen, einem brandenburgischen Landgeistlichen. Das um 1780 veröffentlichte Werk umfasst fünf Bände à ca. 900 Seiten praktischen Wissens über das Führen eines Gutsbetriebes. Es befindet sich auf der Schnittstelle zwischen traditioneller Hausväterliteratur und der Haushaltsliteratur des 19. Jahrhunderts.
Der Autor gehörte der Ökonomischen Aufklärung an, einer Bewegung, die sich für Agrarreformen einsetzte. Die historische Forschung hat bisher die Rolle von Frauen in der Ökonomischen Aufklärung vernachlässigt, Germershausens Hausmutter ist jedoch eine wichtige Figur in der Vermittlung dieses Wissens. Ebenso wichtig ist ihre Aufgabe, die soziale Hierarchie des Hauses herzustellen: Der eigene Stand wird mithilfe des Essens verortet. Bei Gastessen darf weder geprotzt werden, noch darf die Hausmutter zu geizig sein, während das Gesinde auf keinen Fall zu gutes Essen bekommen darf.
Die geforderte Sparsamkeit wird so zu einer Gratwanderung und setzt schließlich nicht mehr nur beim Gesinde, sondern auch bei der Hausmutter selbst an. Die bürgerliche Ehefrau hat in der Folge im Laufe des 19. Jahrhunderts als Laie und unbezahlt immer mehr Aufgaben übernommen. Diese Entwicklung fängt mit dem spätaufklärerischen idealisierten Mutterbild an, das sich auch im letzten Band der Hausmutter finden lässt. In den ersten vier Bänden adressiert Germershausen seine Leserin als kompetente Betriebsleiterin. Dieser Tonfall ändert sich im letzten Band, in dem es um Schwangerschaft, Mutterschaft und die Erziehung der Töchter geht. Der Autor vollzieht hier einen Strategiewechsel in der Propagierung seines Hausmutterideals: vom gesellschaftlichen Druckmittel der Fremdbestimmung zur Selbstdisziplinierung und Affektbeherrschung durch schlechtes Gewissen.In order to understand the concept of the housewife, I took a look at an advice book from the late Enlightenment, the first German household book that addressed exclusively women: Die Hausmutter in allen ihren Geschäfften (The Complete Guide to the activities of the Mistress of the Household) by Christian Friedrich Germershausen, a rural pastor. It was published around 1780, and consisted of five volumes à ca. 900 pages of practical knowledge about how to run a rural estate. It marks a unique position between traditional Hausväterliteratur and household literature from the 19th century. The author belonged to a movement that tried to introduce agricultural reforms. Historical research looking into this ‚Economic Enlightenment‘ has so far neglected the role of women in it. Germershausen, nevertheless, regards the Hausmutter as an important figure in the process of communicating and realizing this knowledge. Equally important is her task to establish the social order in the house: the status in feudal society is defined with the help of food. Having guests for dinner, she is supposed to find the right balance between decadence and parsimony. The servants mustn’t be served food the author regards as too good for them. Eventually, the requested thriftiness doesn’t only concern the servants, but also the Hausmutter herself. During the 19th century, the bourgeois housewife, layperson and unpaid, consequently takes over more and more tasks. This development started with motherhood being idealized in the late Enlightenment, apparent in the last volume of the Hausmutter. While Germershausen still addresses his reader as competent manager in the first four volumes, his tone changes in the last volume, as the subject turns to pregnancy, motherhood, and the upbringing of daughters. The author changes his strategy propagating his ideal of the Hausmutter: from societal pressure of heteronomy to self-discipline and control of affects by means of a guilty conscience.

Schwere psychische Erkrankungen wie Schizophrenie und affektive Störungen haben nicht nur einen erheblichen Einfluss auf das Leben der Patienten, sondern auch ihrer Bezugspersonen. Die Entdeckung der Lebensqualität und ihrer relevanten Faktoren für pflegende Angehörige von Patienten mit psychischen Erkrankungen hilft Gesundheitsfachkräften sowie dem System, besser mit pflegenden Angehörigen zusammenzuarbeiten. Außerdem hilft es den Pflegekräften, auf eine adaptive Weise mit Patienten umzugehen. Die Studie zielte darauf ab, die Belastung und Lebensqualität von Pflegekräften, ihre spezifischen Bedürfnisse und Bewältigungsstrategien zu identifizieren. Außerdem sollte ein neuer Fragebogen entwickelt werden, um die Lebensqualität der Pflegekräfte zu messen.
Diese Studie wendet einen Mixed-Method-Ansatz mit drei explorativen, quantitativen und ergänzenden Phasen an. Die qualitative explorative Phase der Studie wurde mittels halbstrukturierter Interviews mit 45 Betreuern von Patienten mit Schizophrenie und affektiven Störungen durchgeführt. Die Daten wurden durch qualitative Inhaltsanalyse untersucht. Die quantitative Phase diente der Entwicklung und Validierung eines neuen Instruments zur Messung der Lebensqualität von Pflegekräften sowie der Bereitstellung von Hauptfragen des Interviews für die zusätzliche Phase der Studie. Die Ergänzungsphase der Studie wurde in halbstrukturierten Interviews mit 18 Betreuern von Patienten mit Schizophrenie sowie affektiven Störungen durchgeführt. Die Daten wurden mittels Grounded-Theory-Analyse untersucht.
Die Ergebnisse der Studie ermittelten die Hauptbelastungen, denen die Pflegepersonen ausgesetzt waren. Darüber hinaus wurden durch die Entwicklung und Validierung eines neuen Fragebogens die wichtigsten Faktoren für die Lebensqualität aufgedeckt. Ergebnisse der Ergänzungsphase der Studie identifizierten das Kernkonzept der Pflegeerfahrung sowie deren Hauptkategorien. Außerdem werden verschiedene Arten von Bewältigungsstrategien vorgeschlagen, die die Pflegekräfte übernommen haben. Weiterhin zeigt diese Phase die Trajektorie von Pflegeerfahrung und Bewältigungsstrategien in verschiedenen Phasen der Erkrankung.
Die Studie bietet einige Vorschläge für das System, Fachkräfte im Gesundheitswesen sowie Pflegekräfte an, um die Lebensqualität der Pflegekräfte zu verbessern und die Absicht zu vermindern, Patienten einem institutionellen Pflegezentrum anzuvertrauen.Severe mental illnesses, such as schizophrenia and affective disorders, have a considerable impact on the lives of not only patients but also their caregivers. Discovering the quality of life and its contributing factors for family caregivers of patients with mental illnesses helps health-care professionals as well as the system to work better with family caregivers. Also, it helps the caregivers to cope with patients in an adaptive way. The study aimed to identify the burden and quality of life of caregivers, their specific needs and coping strategies. Also, it aimed to develop a new questionnaire to measure caregivers’ quality of life. This study applied a mixed-method approach with three exploratory, quantitative and supplementary phases. The qualitative exploratory phase of the study was conducted via semi-structured interviews with 45 caregivers of patients with schizophrenia and affective disorders. Data were analyzed through qualitative content analysis. The quantitative phase was designed to develop and validate a new instrument to measure caregivers’ quality of life as well as to provide main questions of the interview for the supplementary phase of the study. The supplementary phase of the study was conducted by semi-structured interviews with 18 caregivers of patients with schizophrenia and affective disorders. Data were analyzed by grounded theory analysis. Findings of the study identified main burdens that the caregivers endured; additionally, main factors which contributed to the quality of life were revealed by developing and validating a new questionnaire. Findings of the supplementary phase of the study identified the core concept of caregiving experience as well as its main categories. Also, it proposes different kinds of coping strategies that caregivers adopted. Furthermore, this phase shows the trajectory of caregiving experience and coping strategies in different phases of the illness. The study provides some suggestions for the system, health-care professionals as well as caregivers in order to increase caregivers’ quality of life and to lessen the intention to entrust patients to an institutional take care center.

Full textAbstract:
Weltweit migrieren Männer und Frauen, ihre Arbeitsmarktintegration ist jedoch grundsätzlich verschieden. Erklärungen hierfür sind bislang unzureichend. Daher entwickelt diese Dissertation ein Konzept zu Migration, Geschlecht und Erwerbstätigkeit, dessen Kernargument ist, dass sich Geschlechterunterschiede über die Immigration reproduzieren. Die Papiere der Dissertation testen drei Mechanismen, die diesen Prozess bedingen können. Im ersten Papier betrachtet diese Dissertation die folgende Frage: Wie wirken sich Dynamiken in den Migrationsentscheidungen von Paaren auf deren Erwerbstätigkeit aus? Das Papier diskutiert diese Frage im Licht der tied migration theory. Zur empirischen Analyse zieht das Papier Daten des Sozio-oekonomischen Panels (SOEP) heran. Es zeigt sich, dass Männer, die die treibende Kraft der Entscheidung waren, nach Migration beruflich erfolgreicher sind als Männer, deren Partnerin die Entscheidung traf. Das zweite Papier fragt: Wie entwickelt sich die Zeit, die Frauen und Männer auf Hausarbeit verwenden, über den Migrationsprozess? Hierfür bezieht sich das Papier theoretisch auf Neoklassische Theorie und Verhandlungstheorie sowie auf Ideen der Geschlechterkonstruktion und integriert migrationsspezifische Aspekte. Für die Analysen verwendet das Papier Daten des SOEP und Angaben zur Zeitverwendung. Die Resultate des Papiers zeigen, dass die Hausarbeit für Männer und Frauen nach Migration stark ansteigt, jedoch nur kurzfristig. Im dritten Papier betrachtet diese Dissertation die Sozialisierung von Migrantinnen. Das Papier fragt: Wie beeinflusst die Sozialisierung von Migrantinnen ihre Erwerbstätigkeit? Die theoretische Herleitung des Papiers beruht auf der Sozialisationstheorie, die Analysen beruhen auf Daten des SOEP. Das Papier schlussfolgert, dass die Sozialisierungsanstrengungen von Müttern gesellschaftliche Effekte abfedern können. Zusammenfassend verdeutlicht diese Dissertation die Bedeutung von geschlechtsspezifischer Integrationsforschung.Women and men are on the move, yet their employment experiences after migration differ. To date, evidence on underlying reasons is scarce. Hence, this dissertation develops a framework for understanding migration, gender, and employment. This framework argues that gender inequalities are reinforced across migration. In its empirical chapters, this dissertations tests three mechanisms hypothesized to drive this process. This dissertation’s first paper addresses the following question: How do dynamics in couples’ decision to migrate impact the employment of migrant women and men? Theoretically, this puzzle is discussed with regard to tied migration theory. Empirically, the paper analyzes data on couples’ migration decisions from the German Socio-Economic Panel (SOEP). The results show that migrant men who drove decisions are vocationally more successful after migration than men whose partners initiated migration. The second paper of this dissertation asks: How does migration impact the time spent on domestic work of immigrant women and men? Therefore, the paper draws on theoretical notions of Neoclassical Economic and Bargaining Theory, ideas of Gender Construction, and integrates migration-specific aspects. For its analyses, the paper uses SOEP data and couples’ time use. The results of this paper indicate that the time spent on domestic work increases drastically for migrant women and men after migration, yet only in the short-term. The third empirical paper of this dissertation looks at female migrants’ socialization. It asks: How does adolescent socialization impact the employment of immigrant women? The paper’s hypotheses are based on Socialization Theory, it bases its analyses on SOEP data. The paper concludes that mothers and their socialization efforts can buffer societal impacts. Overall, this dissertation emphasizes the significance of gendered integration research and the necessity to further explore the differential employment of migrant women and men.

Full textAbstract:
Diese Arbeit beleuchtet die wichtigen Komponenten des Habitus indischer Arbeitsplätze von Organisationen des privaten und öffentlichen Sektors in Delhi und zeigt auf, wie tief die in beiden Arbeitssektoren vorherrschenden geschlechtsspezifischen Ungleichheiten in ihren Habitus eingebettet sind. Der Zusammenhang zwischen Habitus und geschlechtsspezifischen Ungleichheiten wird durch im Rahmen dieses Projekts durchgeführte Forschungen und Feldstudien aufgezeigt, die zeigen, wie sich das Ausmaß, die Wahrnehmung, die Reaktion und der allgemeine Ansatz zur sexuellen Belästigung am Arbeitsplatz zwischen den Bereichen des öffentlichen und des privaten Sektors stark unterscheiden. Sexuelle Belästigung und unangemessenes Verhalten am Arbeitsplatz werden als Indikatoren für die Aufdeckung von Ungleichheiten zwischen den Geschlechtern im öffentlichen und privaten Sektor verwendet. Daher stellt diese These die Erforschung zweier zentraler Konzepte dar, d. H. Habitus- und Geschlechterungleichheiten, indem das Verständnis und die Herangehensweise an sexuelle Belästigung in beiden Sektoren untersucht werden und somit die Verbindung zwischen Habitus und Geschlechterungleichheit am indischen Arbeitsplatz begründet wird.This thesis highlights the important components of the habitus of Indian workplaces of private and public sector organisations in Delhi and establishes how gender inequalities prevalent in both work sectors are deeply embedded in their habitus. The connection between habitus and gender inequalities is demonstrated by research and field studies conducted within this project that exhibit how the scale, perception, reaction and overall approach to sexual harassment at the workplace differs extensively between fields of public and private sector. Sexual harassment and inappropriate behaviour at the workplace are used as signifiers for the exposition of gender inequality in public and private sectors. Therefore, this thesis constitutes the exploration of two central concepts i.e. habitus and gender inequalities by studying the understanding of and approach towards sexual harassment in the two sectors and thus, substantiate the linkage betwixt habitus and gender inequality at the Indian workplace.

Doctoral thesis, Örebro universitet, Institutionen för naturvetenskap och teknik, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:oru:diva-30070.
Full textAbstract:
Contaminated soils are a worldwide problem. Polycyclic aromatic hydrocarbons (PAHs) are common contaminants in soil at former industrial areas, especially at old gasworks sites, gas stations and former wood impregnation facilities. Risk assessments of PAHs in contaminated soils are usually based on chemical analysis of a small number of individual PAHs, which only constitute a small part of the complex cocktail of hundreds of PAHs and other related polycyclic aromatic compounds (PACs) in the soils. Generally, the mixture composition of PAH-contaminated soils is rarely known and the mechanisms of toxicity and interactions between the pollutants are far from fully understood. The main objective of this thesis was to characterize remediated PAHcontaminated soils by use of a chemical and bioanalytical approach. Bioassay specific relative potency (REP) values for 38 PAHs and related PACs were developed in the sensitive H4IIE-luc bioassay and used in massbalance analysis of remediated PAH contaminated soils, to assess the contribution of chemically quantified compounds to the overall aryl hydrocarbon receptor (AhR)-mediated activity observed in the H4IIE-luc bioassay. Mixtures studies showed additive AhR-mediated effects of PACs, including PAHs, oxy PAHs, methylated PAHs and azaarenes, in the bioassay, which supports the use of REP values in risk assessment. The results from the chemical and bioassay analysis showed that PAH-contaminated soils contained a large fraction of AhR activating compounds whose effect could not be explained by chemical analysis of the 16 priority PAHs. Further chemical identification and biological studies are necessary to determine whether these unknown substances pose a risk to human health or the environment. Results presented in this thesis are an important step in the development of AhR-based bioassay analysis and risk assessment of complex PAH-contaminated samples.Other funders: Sparbanksstiftelsen Nya and Ångpanneföreningen

Full textAbstract:
In den Jahren 1992-1995 kamen ca. 35 Tausend bosnische Kriegsflüchtlinge nach Berlin und wurden vorübergehend geduldet. Nach Kriegsende 1995 sollten sie schnellstmöglich wieder zurückkehren. Traumatisierte und Ältere ohne Angehörige im Heimatland wurden weiterhin geduldet bis Bosnien-Herzegowina wieder aufgebaut ist. Doch der Wiederaufbau verlief schleppend. Mit dem Friedensvertrag von Dayton begannen nicht Frieden und Wiederaufbau, sondern die Konsolidierung der ethnischen Grenzen in demokratischen Strukturen. Deshalb sahen viele Flüchtlinge keine Möglichkeit in ihre Heimatorte zurückzukehren und versuchten ihre Rückkehr hinauszuschieben. Möglich war dies mithilfe der Attestierung einer kriegsbedingten Posttraumatischen Belastungsstörung und ihre psychotherapeutische Behandlung, die den Inhabenden und ihren Familienmitgliedern eine Aufenthaltsverlängerung ermöglichte und ab dem Jahr 2000 den Erhalt eines dauerhaften Aufenthaltstitels. Die Verbindung einer psychischen Krankheit und ihrer Psychotherapie mit einem Aufenthaltsrecht ist neu in der Geschichte des deutschen Ausländerrechts und obwohl Berliner Psychiater, Psychiaterinnen, Psychologinnen und Psychologen maßgeblich an der Schaffung der „Traumatisiertenregelung“ beteiligt waren, wurden ihre Atteste von der Berliner Verwaltung in Frage gestellt. In der Dissertation werden die Standpunkte der Flüchtlinge, Behandelnden und der Verwaltung dargelegt und ihre Interaktionen beschrieben.Die Rolle des Krankheitskonzeptes der Posttraumatischen Belastungsstörung wird als "boundary object" (Star/Griesemer 1989) untersucht. Der Schwerpunkt liegt auf den Lebenswelten und Taktiken der Flüchtlinge, sich in Berlin zurechtzufinden und Anerkennung und Verständnis für ihre Situation zu finden. Ihre Bedürfnisse wurden in einen psychotherapeutischen Bedarf übersetzt und damit den Berliner Psychotherapeutinnen und -therapeuten ein neues Betätigungs- und Professionalisierungfeld geboten, was kritisch hinterfragt wird.From 1992 until 1995 about 35 thousand Bosnian war refugees fled to Berlin and were allowed to stay temporarily. After the end of the war in 1995 they were expected to leave as soon as possible. Traumatized persons and elderly without relatives in Bosnia had the possibility to prolong their visa until Bosnia is reconstructed. But the rebuilding process progressed only slowly. With the end of the war did not start the expected peace time and rebuilding but the consolidation of ethnic borders inside democratic structures. Therefore many refugees did not see a possibility to return to their property and tried to delay their return. This was possible with an medical statement certifying a war related posttraumatic stress disorder and their psychotherapeutic treatment. These medical statements ensured the extension of the visa for the concerned person and its family members. From 2000 onwards they could receive a permanent residence title. The connection of a mental illness and psychotherapy with residence entitlements is a novelty in the German aliens law. And despite the fact that psychiatrists and psychologists from Berlin were leading actors in the establishment of the „regularization of the traumatized“ their medical/psychological statements were impeached by the authorities. The dissertation describes the viewpoints of refugees, treating physicians and psychologists and the authorities and how they interact with each other. Additionally is the concept of posttraumatic stress disorder examined and discussed as „boundary object“ (Star/Griesemer 1989). An important aspect is the description of life worlds and tactics of the refugees to get along in Berlin, to gain respect and appreciation for their situation. Their needs were translated into a psychotherapeutic demand and this led to the invention of a new field of work and professionalization for psychotherapists in Berlin. This development is critically reflected.

Die folgende Dissertation, die im Mai 2016 verteidigt wurde, beschäftigt sich mit sprachlichen Manifestationen von Genderkonzeptualisierungen im aktuellen schriftlichen Sprachgebrauch in Kroatien. Die Bedeutung von Genderzuschreibungen für die Benennung von Menschen wird sowohl aus synchroner als auch aus diachroner Perspektive auf Sprache betrachtet und analysiert. Das Material dieser Studie besteht neben sprachlichen und präskriptiven Quellen aus Tageszeitungen und linguistischem Material aus der kroatischen feministisch-queeren Gemeinschaft auch aus den Ergebnissen einer umfassenden Perzeptionsstudie und Expert*inneninterviews.
Die Arbeit befasst sich mit drei zentralen Fragen:
1. Wie beeinflussen soziale Gendervorstellungen Fragen linguistischer Standardisierungsprozesse und wie werden diese Vorstellungen zudem in dominante Diskurse über Korrektheit im Sprachgebrauch eingeschrieben?
2. Welche Wirkung auf Genderkonzeptionen haben Sprachnormen im Bereich der personalen Appellation und welche kognitive Wirkung haben alternative Benennungsformen?
3. Welche Bedeutung haben Fragen des geschlechtergerechten Sprachgebrauchs bei politischen und aktivistischen Bemühungen von Genderexpert*innen in Kroatien und welche Strategien verwenden kroatische Genderexpert*innen, um eine diskriminierende Sprachnutzung zu vermeiden?This dissertation thesis, which was defended in May 2016, deals with linguistic manifestations of gender conceptualizations in current written language usage in Croatia. The importance of gender for the linguistic naming of people is considered and analyzed from both a synchronic and a diachronic perspective on language. In addition to linguistic and prescriptive sources, the material of this study consists of daily newspapers and material from the Croatian feminist-queer community as well as oft he results of a perception study and expert inteviews. The thesis deals with three central questions: 1. How do social gender conceptions influence questions of linguistic standardization processes and how are these conceptions inscribed in dominant discourses about correctness in language use? 2. What effect do linguistic norms have on gendered conceptions of people and what is the cognitive effect of alternative naming practices? 3. What meaning is allocated to questions of gender-fair language use in political and activist efforts of gender experts in Croatia and what strategies do Croatian gender experts use to avoid discriminatory language use?

Full textAbstract:
The first visible outcome of the fertility process is the birth of the first child. The first birth marks a woman's transition into motherhood. It plays a significant role in the future life of each individual woman and has a direct relationship with fertility. The age at which child bearing begins influences the number of children a woman bears throughout her reproductive period in the absence of any active fertility control. For countries in sub-Saharan Africa, where contraceptive use is relatively low, younger ages at first birth tend to boost the number of children a woman will have. However, even when family planning is widespread, the timing of first births can affect completed family size if contraception is used for spacing but not for limiting fertility. The birth of a child is an event of great social and individual significance and its importance is recognised in all human societies. It signifies the transition of a couple into a new social status, i.e. parenthood with its related expectations and responsibilities. It marks the sexual and social maturity of the mother and the visible consummation of sexual intercourse . The relationship between age at first birth and overall fertility in developing countries is generally an underdeveloped area as far as demographic research is concerned. Fertility analysts generally assume that child bearing only occurs within marriage. Then they treat age at first marriage to be a major proximate determinant of fertility. This assumption might have been true in most traditional societies, where births out of wedlock were not accepted and virginity was a prerequisite for marriage. This assumption, however, does not hold true in modern times, where a large number of children is born outside marriage. These facts have been the major motive of conducting the current research. This study examines the reproductive behaviour of Tanzanian women. The study found the average age at first sexual intercourse to be 16 years; age at first marriage to be 17 years, while average age at first child bearing was estimated to be 18 years. By age 15, almost 10 percent of juvenile women have given birth. This study furthermore found that 41 percent of all first live births resulted from premarital conceptions. Out-of-wedlock births account for 24 percent of all first births in Tanzania according to the 1996 TDHS. The education of a woman, place of residence, and religion play the greatest roles in influencing age at first birth in Tanzania. The striking results were place of residence as it was found that rural residents have a higher mean age at first birth than women living in Dar es Salaam. Dar es Salaam women has the lowest mean age at first birth. Moslems have lower age at first birth than Catholics. There is also a strong relationship between age at first birth and age at first intercourse also with infant and child mortality. The results indicate that the younger the age of the mother at the birth of the first child, the higher the chances that the child dies. The study of current levels and trends of fertility showed that, on the average, a Tanzanian woman bears 6 children. Between the 1960s and early 1980s, an average of 7 births per woman prevailed in Tanzania. The declining fertility in Tanzania was confirmed by the analysis of the decomposition of the change of the total fertility rate (TFR) between two TDHSs. It found that natural fertility control is being gradually replaced by contraceptive use although the percentage of women using contraception is still very low. The reduction in infant and child mortality, rising numbers of women attending schools, and a rise in age at first birth are among the factors responsible for the decline in fertility in Tanzania. Education on the other hand has played a major role in raising age at first birth. Education either delays first intercourse and subsequently birth as pregnant schoolgirls are prohibited to attend formal schools or it effects the acceptance of contraception to delay first conception. Specifically, this study establish that there is an inverse relationship between age at first birth and fertility. Marriage is a weak factor in explaining fertility in Tanzania. Women in polygamous unions had fewer number of children ever born than those in monogamous unions in Tanzania. Moslems have a lower fertility than Catholics. Women residing in urban areas have fewer children than those in the rural areas. Women's education is the strongest predictor of the use of contraceptives in Tanzania. Catholic women are less likely to use contraceptives than Moslems. Tanzanian women residing in rural areas are less likely to use contraception than their counterparts residing in urban areas. Although age at first birth did not show any significance, age at first intercourse, age at first marriage and current age are highly related to contraceptive use. Variation in age at first sexual intercourse; marriage; and birth, and the extent of practising contraception are found to depend mainly on religion, place of residence, and the age of a woman. It is important therefore to design separate programmes to raise age at first birth and to lower fertility according to the findings related to religion, place of residence, and target juvenile women separately.

This chapter discusses, in the context of the predictive-coding framework, evoked responses to various changes in the environment and describes how the responses are related to variations in stimulus probability and the subject’s expectations. The focus is on three well-known responses: (a) the mismatch negativity peaking at 100 to 250 ms and elicited to changes in stimulus attributes, even when the stimuli are not attended to, (b) the P300 response peaking about 300 ms after attended low-probability “oddball” stimuli, and (c) the N400 peaking about 400 ms after semantic or lexical violations of sentences presented either visually or auditorily. Continent negative variation and error-related negativity are introduced as well.

Full textAbstract:
Though the biomarker saga began with attempts to understand the ancient provenance of petroleum and with the concept of “fossil molecules” and search for early forms of life, the explorations of the past 50 years have led organic geochemists far afield of these first endeavors. As Geoff and Max Blumer recognized back in the 1960s, and as microbiologists began to realize in the early 1980s, the usefulness of the biomarker concept is not restricted to geologic time. Most organic geochemists have, at one time or another, applied their techniques and expertise to the resolution of environmental problems, or found a way to address some archaeological mystery. One of the Bristol group’s most vibrant research programs now has its chemists brushing shoulders not with geologists and oceanographers, but with archaeologists and anthropologists concerned with the evolution of human civilizations and societies. Much of the impetus for the application of biomarker concepts to archaeologists’ questions in the 1970s and 1980s came from petroleum geochemists, not least from Arie Nissenbaum, a geochemist at Israel’s Weizmann Institute of Science who developed a keen interest in the role that geological events and circumstance might have played in the history of civilizations in the Fertile Crescent region. Nissenbaum was fascinated by the bizarre geology and chemistry of the Dead Sea Basin area, where oil seeps and impressive raftlike chunks of asphalt floating on the surface of the lake had long tempted oil prospectors to no avail. Renewed interest in the area’s oil potential in the early 1980s attracted a wave of geochemical studies, and Israeli geochemists scrambled for laboratory resources and funding from abroad. Jürgen, still with Dietrich Welte’s group, did a detailed biomarker study at the behest of an Israeli colleague, and when Nissenbaum saw the results he suggested to Jürgen that they apply Jülich’s considerable GC-MS capability to solving an entirely different sort of mystery. Excavations of archaeological sites in the vicinity of the Dead Sea had turned up solid chunks of black, sticky material that was used as early as 3000 B.C., either in materials used for construction or as a glue to attach tool heads to wooden handles.

Full textAbstract:
Over the past 20 years, gas chromatography/mass spectroscopy (GC/MS) has been widely used to identify trace organic environmental contaminants and to study the mechanisms of the formation or transformation of organic compounds either by natural or man-made processes. In the area of water and wastewater disinfection, GC/MS has been highly successful in identifying numerous volatile organic chlorination by-products, some of which may pose undesirable health risks to humans and aquatic organisms at concentrations found in some waters. However, despite a considerable amount of research in this area much of the chemistry continues to be poorly understood. Analysis of trace organics by GC/MS relies on the assumption that the compounds to be analyzed are (1) volatile and (2) thermally stable to GC temperatures as high as 300 °C. Because nuclear magnetic resonance spectroscopy (NMR) is a mild and nondestructive method of analysis, it can reveal reactions that occur in water that cannot be observed by GC/MS. Until recently the reactions of amino acids with two or more equivalents of aqueous chlorine were believed to produce aldehydes and nitriles according to equation (1). LeCloirec and Martin have reported that the formation of nitriles in such situations may come in part from the reaction of monochloramine with aldehydes (equation (2)). Because reaction (2) may affect the distribution of products in reaction (1), it was important to determine the relationship between these two reactions. This chapter will review the applications of NMR we have used in studies of the products formed upon chlorination of amino acids.

The authors of the ToL have reunited in Title V of Part V rules of a quite distinct nature. Article 216 TFEU contains in its paragraph 1 a newly inserted provision to the effect that the EU may conclude international agreements (IAs). In paragraph 2, it contains the former Article 300(7) EC concerning the legal effect of such agreements on the Union itself and on its MS. From a systematic point of view, its rules would have better fitted in either Part I Title I TFEU (competences) or Part V Title I (general provisions on the EU’s external action).

Full textAbstract:
In this chapter, results of our recent investigations on the structural, microstructural and magnetic properties of Cu-based Heusler alloys and MFe2O4 (M = Mn, Fe, Co, Ni, Cu, Zn) nanostructures will be discussed. The chapter is divided into two parts, the first part describes growth and different characterizations of Heusler alloys while in the second part magnetic properties of nano-ferrites are discussed. The Cu50Mn25Al25-xGax (x = 0, 2, 4, 8 and 10 at %) alloys have been synthesized in the form of ribbons. The alloys with x ≤ 8 show the formation of Heusler single phase of the Cu2MnAl structure. Further increase of Ga content gives rise to the formation of γ-Cu9Al4 type phase together with Cu2MnAl Heusler phase. The alloys are ferromagnetically ordered and the saturation magnetization (Ms) decreases slightly with increasing Ga concentration. Annealing of the ribbons significantly changes the magnetic properties of Cu50Mn25Al25-xGax alloys. The splitting in the zero field cooled (ZFC) and field cooled (FC) magnetization curves at low temperature has been observed for alloys. Another important class of material is Nanoferrites. The structural and magnetization behaviour of spinel MFe2O4 nanoferrites are quite different from that of bulk ferrites. X-ray diffraction study revealed spinel structure of MFe2O4 nanoparticles. The observed ferromagnetic behaviour of MFe2O4 depends on the nanostructural shape as well as ferrite inversion degree. The magnetic interactions in Ce doped CoFe2O4 are antiferromagnetic that was confirmed by zero field/field cooling measurements at 100 Oe. Log R (Ω) response measurement of MgFe2O4 thin film was taken for 10–90% relative humidity (% RH) change at 300 K.

Full textAbstract:
ABSTRACT This study experimentally evaluated exhaust emissions from methanol-gasoline blend (G95) and pure gasoline (G100) fuels using Spark Ignition (SI) engine. We produced methanol from Carbon (IV) Oxide (CO2) and water for transport and other applications. The methanol production involved simultaneous electrolysis of water within the anodic half-cell and catalytic reduction of CO2 within cathodic half-cell of an electrochemical set-up. We separated the produced methanol from its solution by fractional distillation. G95 was a mixture of 5 percent of methanol and 95 percent of gasoline. The experimental engine was naturally aspirated, single cylinder, 4-stroke with port-fueled injector. We operated the engine under constant load of 3000 kg with varying engine speeds of 2200, 2600, 3000, 3400, 3800, and 4200 rpm. The experimental test results showed that CO and uHC emissions by G95 are lower than that of G100 at all engine speeds. However, CO2 and lambda (λ) emissions by G95 are higher than that of G100 specifically at full load operations. The results found in this study highlight that application of methanol in transportation industry has high potential to lessen vehicle's emissions and improve atmospheric environment.
