description: Looked after children and young people are a vulnerable group of minors exposed to adverse childhood experiences (ACEs), who have greater health needs. This study explored the health characteristics of the population of Looked after children and young people residing in residential care in the Maltese Islands run by the newly established looked after children and young people healthcare service, which also coincided with the relaxing of Covid-19 restrictions. The quantitative data were gathered in the form of a prospective audit. The population of looked after children and young people (N=200) showed that 90 per cent (n=180) were victims of child maltreatment. Ninety-four per cent (n=188) had at least one physical health issue, 60 per cent (n=119) at least one mental health problem, and 59 per cent (n=20) of minors under six had at least one developmental issue identified. Thirty-seven per cent (n=63) of looked after children and young people in school were statemented, indicating significant learning difficulties. Forty-four per cent (n=72) were found to be overweight/obese. This study highlights the importance of specialised healthcare services for looked after children and young people that can detect health needs specific to this group and influence pathways and policies to help improve their health outcomes. Findings further emphasise the importance of therapeutic care settings, with trauma-informed staff, who can promote resilience in looked after children and young people.

description: It is possible that there are additional vector-like generations where the quarks have mass terms that do not originate from weak symmetry breaking, but the leptons only get mass through weak symmetry breaking. We discuss the impact that the new leptons have on Higgs boson decay branching ratios and on the range of allowed Higgs masses in such a model (with a single new vector-like generation). We find that if the fourth generation leptons are too heavy to be produced in Higgs decay, then the new leptons reduce the branching ratio for h -> gamma gamma to about 30% of its standard-model value. The dependence of this branching ratio on the new charged lepton masses is weak. Furthermore the expected Higgs production rate at the LHC is very near its standard-model value if the new quarks are much heavier than the weak scale. If the new quarks have masses near the cutoff for the theory then for cutoffs greater than 10^15 GeV, the new lepton masses cannot be much heavier than about 100 GeV and the Higgs mass must have a value around 175 GeV.

description: Steam Assisted Gravity Drainage (SAGD) process has been applied over wide area of the Province of Alberta, boosting the Canadian oil reserves to the position of third highest in the world. A key performance indicator of SAGD thermal efficiency is the steam-oil-ratio (SOR) that is the volume of water converted to steam and injected into the formation for each unit volume of produced oil. Even though several cost-saving advances have been made in this technology, SAGD remains expensive in terms of both the oil production cost and the environmental cost associated with greenhouse gases (GHG) emissions. Several kinds of additives have been proposed for improving the thermal efficiency of the process and decreasing the SOR while increasing the cumulative oil recovery. Solvent addition in SAGD is one alternative that improves the performance by decreasing the oil viscosity by dilution and thereby by decreasing the required amount of heat per produced oil barrel. In solvent enhanced SAGD, a part of steam volume is replaced by hydrocarbon solvent, in order to take advantage of not just heat but also of dilution for viscosity reduction. At the same time, solvent injection reduces heat losses by reducing the operating temperature. The combination of reservoir characteristics and operational constraints influence the choice of solvent as well as its concentration and timing. No systematic study of residual oil saturation (Sor) in solvent enhanced SAGD has been reported in the literature. This project tested four solvents (Pentane -C5H12, Hexane -C6H14, Cracked Naphtha and Natural Gas Condensate) at different concentrations using linear sand-packs that simulated SAGD gravity drainage to quantify their impact on the recovery performance during the injection process and on the residual oil saturation. The addition of all tested solvents to steam increased the rate of oil drainage and reduced the residual oil saturation. Amongst the single component solvents, 15 vol% hexane gave the fasted recovery and lowest residual oil saturation. However, the multicomponent solvents performed even better. Addition of 15 vol% cracked naphtha gave the lowest residual saturation and fastest oil recovery. The performance of gas condensate was also impressive. At 5 vol% concentration it was able to outperform 10 vol% cracked naphtha and 15 vol% hexane in terms of the rate of oil recovery and residual oil saturation.

description: This paper explores how “framing from afar,” in other words, the construction of categories by external agents—policy makers, regulators, local governments, consulting firms and other actors—influences the establishment and subsequent evolution of a new industry. We use the case of the Japanese microbrewery industry to demonstrate how initial external category-setters shape the evolution of the industry by influencing the type of producers that enter and what they produce. We show that external agents used the pre- existing term “jibiru” – meaning regional or local beer – to define the new industry in terms of regional economic growth. This broad category framing served to legitimate entry by producers from a diverse range of backgrounds, and invited extreme experimentation around local and regional ingredients; it also made it difficult for the industry to reach a shared consensus on the taste and characteristics of the products. Our findings contribute to the literature on industry emergence by demonstrating how early category framing by external actors – whose interests may diverge from those of consumers and producers – may impact the nature of entrants, their product development choices, as well as the long-run legitimacy of the industry itself.

description: We study the evolution of a two dimensional minisuperspace cosmological model in classical and quantum levels by the Noether symmetry approach. The phase space variables turn out to correspond to the scale factor of a Friedmann-Robertson-Walker (FRW) model and a scalar field with which the action of the model is augmented. It is shown that the minisuperspace of such a model is a two dimensional manifold with vanishing Ricci scalar. We present a coordinate transformation which cast the corresponding minisuper metric to a Minkowskian or Euclidean one according to the choices of an ordinary or phantom model for the scalar field. Then, the Noether symmetry of such a cosmological model is investigated by utilizing the behavior of the corresponding Lagrangian under the infinitesimal generators of the desired symmetry. We explicitly calculate the form of the scalar field potential functions for which such symmetries exist. For these potential functions, the exact classical and quantum solutions in the cases where the scalar field is an ordinary or a phantom one, are presented and compared.

description: Twentieth and 21st century Eastern Christianity in the United States has faced several challenges that reflect broader patterns in American history, Russian history, immigrant and global history. From the first arrival of Russian Orthodox clerics to Alaska in 1794, the Orthodox Church in North America had been fundamentally an immigrant community served by bishops and priests sent from Russia. In 1905, however, signaling a new appreciation of the permanent presence of Russophone Eastern Christians in America, Archbishop Tikhon (Beliavin, later the martyred Patriarch of Moscow) decided to establish a permanent seminary here. This move was prescient. The Russian Revolutions of 1917 inaugurated a crisis and a turning point for Russian-speaking Eastern Christians in America. On the one hand, Eastern Christians in America lost material support from Russia and were divided in their assessments on a number of issues: their further relation with the persecuted and compromised Orthodox Church in Russia, the language of religious services and publications, and the Julian Church calendar. Russian-speaking Eastern Rite Catholics were similarly divided on the policies of the Vatican. On the other hand, the numbers of Russian-speaking Eastern Christian refugees escalated. All this, combined with the hostility of the American government towards the communist Soviet Union, created a situation that grew even sharper and richer after World War II, with the arrival from Europe of so-called 'Second Wave' émigrés, including renowned Russophone scholars, clerics, and theologians. Each ‘wave’ of Russophone immigrants, including the so-called 'Third' (primarily Jewish) and Fourth, has brought a new assessment of religion in both public and private spheres, new attitudes toward language and culture, new opportunities to maintain contacts with Russia and Russian speakers in the former Soviet Union, and new opportunities to convert from one religion to another. The plurality of religious positions among Russian speakers in America has allowed for a diversity of educational institutions (including St. Vladimir's Seminary, Holy Trinity Seminary, and St. Tikhon's Orthodox Seminary), monasteries, and jurisdictions (including the Russian Orthodox Church Outside of Russia, the Orthodox Church in America, and the Moscow Patriarchate). The changed political and economic situation in Russia has created opportunities for 'reverse' emigration, with native-born Americans returning to the land of their Russophone ancestors. The story of Russian-speaking Eastern Christians in 20th and 21st Century America is thus no less than a microcosm of both modern American—and modern Russian—history.

description: This dissertation reports experiments and simulations of micro-/nanoscale electrical breakdown, connects them to the microscale breakdown theories, relates them to field emission and space-charge-limited conditions, and demonstrates the modification of the approach to microwave fields. It provides the first comprehensive experimental assessment of the transitions between electron emission and gas breakdown mechanisms at microscale and nanoscale and extension of semi-empirical laws for ionization process in DC and microwave. These findings will be valuable in developing theories to predict electron emission and gas breakdown mechanisms, which provides guidance for nanoscale device design.

description: The impact of four waves of Russophone refugees and immigrants has been transformative of American approaches, attitudes, and appreciation of European culture, theology, philosophy, and ecumenical relationships. The lives and works of these men and women have exerted a paradigm-changing influence on the artistic, spiritual, and academic life of America. The First Wave put down roots across the country and altered the way American society functioned in politics, labor relations, and religion. The Second Wave included influential iconographers such as Dmitry Alexandrov and Pimen Sofronov; culturologists like Helene Iswolsky and Andrei Urusov; historians Nicholas Arseniev and George Fedotov; philosophers Nicholas Lossky and Eugene Spektorsky; and ecumenists Georges Florovsky, John Meyendorff, Alexander Schmemann, and Leonid Kishkovsky. The Third and Fourth Waves brought vigor onto the American academic scene, revitalizing and broadening the horizon of the study of Eastern Europe and Russia and creating new relationships between Russia and the United States. Their fruit of their initiatives and accomplishments constitutes a signal aspect of twenty-first globalization. In the aggregate they strove to express their backgrounds, cultures, and views both intramurally to their own communities; and extramurally to the broader American public. They indigenized their presentations, making them accessible to this broader audience, profoundly changing America’s intellectual and creedal landscape. Finally, they fundamentally transformed theological conversations among Christians in America and internationally, in the academy, in interreligious convocations, and in local parish settings. The dispositive role of these figures in the deliberations and decisions of the National and World Councils of Churches and at the Second Vatican Council is incalculable. An analysis of their achievements and legacies will provide multiple challenges to our thinking and a richer appreciation of their lasting significance. It will also make possible a full integration of these decades of history into America’s scholarly calculus.

description: The influence of electromagnetic fields on the creation of scalar particles from vacuum in a flat Robertson-Walker space-time is studied. The Klein Gordon equation with varying electric field and constant magnetic one is solved. The Bogoliubov transformation method is applied to calculate the pair creation probability and the number density of created particles. It is shown that the electric field amplifies the creation of scalar particles while the magnetic field minimizes it.

description: “Language Teaching and Curricular Development for Russian Immigrants: Re-Adapting to Russian Culture in America?” The so-called third and fourth wave immigrants from Russia have forced many universities and colleges to adjust their teaching of Russian in order to accommodate students whose native language is Russian. We have always had the occasional student in our language classes who spoke Russian at home with parents or grandparents, but since the 1970s this number has increased dramatically. Most of these students, whom we call heritage speakers, have spoken Russian at home before they began to learn English, which we can call the dominant language of their environment, and Russian therefore remains a language that has not been completely acquired. There is considerable variation in the proficiencies of our heritage students but they nevertheless are better grounded in Russian than the average American student of Russian. This situation presents several challenges at the college level. Most heritage speakers of Russian want to exempt a two-year foreign language requirement and many of them are quite fluent in Russian, far more fluent than American students in a second-year Russian course. But very often speaking and oral comprehension skills are the only ones these heritage students have. The instructor has to decide whether or not to exempt a person like this from a language requirement. Some heritage speakers want to take Russian for an easy “A.” This often leads to resentment towards these students by American students. Thus the largest challenge is how to integrate heritage speakers into the classroom, especially in a small college or a university that does not have many heritage speakers, and create a separate curriculum for them.

description: Laporte et al. (2011) reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z=9.6-12, the probability density function for which permits no low or intermediate z solution. We here report new spectroscopic observations of this galaxy with VLT/XShooter, which show clear [OIII]5007AA, Ly-alpha, H-alpha, and H-beta emission and place the galaxy firmly at z=2.082. The oxygen lines contribute only ~25% to the H-band flux, and do not significantly affect the dropout selection of J1. After correcting the broadband fluxes for line emission, we identify two roughly equally plausible natures for A2667-J1: either it is young heavily reddened starburst, or a maximally old system with a very pronounced 4000AA break, upon which a minor secondary burst of star formation is superimposed. Fits show that to make a 3 sigma detection of this object in the B-band (V-band), imaging of depth AB=30.2 (29.5) would be required - despite the relatively bright NIR magnitude, we would need optical data of equivalent depth to the Hubble Ultra Deep Field to rule out the mid-z solution on purely photometric grounds. Assuming that this stellar population can be scaled to the NIR magnitudes of recent HST/WFC3 IR-selected galaxies, we conclude that infeasibly deep optical data AB~32 would be required for the same level of security. There is a population of galaxies at z~2 with continuum colours alone that mimic those of our z=7-12 candidates.

description: While strategic management scholars and institutional theorists regularly debate the merits of organizational differentiation and innovation vs conformity and embeddedness, few studies have sought to empirically investigate how these seemingly opposing forces impact each other. Drawing on both qualitative and quantitative data, we contribute to closing this research gap by exploring how post-entry embeddedness impacted innovation and survival among de-novo and de-alio entrants into the Japanese microbrewery industry. Our findings indicate that post-entry embeddedness has contrasting effects, reducing overly non-conformist strategies among de-novo entrants, but enhancing non-conformity among de-alio entrants. These results indicate how institutions can serve as enablers of innovation, rather than constraints, through their dissemination of standards, norms and industry practices.
Furthering our understanding of asexuality : an investigation into biological markers of asexuality, and the development of the Asexuality Identification Scale
Creators: name: Yule, Morag Allison
Publisher: name: University of British Columbia

description: Human asexuality is defined as an absence of sexual attraction to anyone. Approximately 1% of the population is thought to be asexual. However, there has been a paucity of research into correlates of asexuality as well as into how asexuality is best conceptualized. This is in part due to logistical difficulties in recruiting and identifying representative samples of asexuals. Because of the low prevalence rate of asexuality, and the relatively recent emergence of asexual communities, many individuals who lack sexual attraction may not self-identify as asexual. Previous studies have recruited asexual participants via online web-communities, and relied on self-identification as asexual, which may result in non-representative sampling. The purpose of this study was two-fold. Firstly, in response to continuing debate as to whether asexuality is better understood as a sexual orientation or as a sexual dysfunction, Study 1 aimed to investigate the claim that asexuality would best be conceptualized as a sexual orientation in a large internet sample. Biological markers such as finger length ratios, handedness, and older siblings have may be related to prenatal development, and have been linked to sexual orientation. Asexual men and women were more likely to be non-right-handed than their heterosexual counterparts, and there were significant differences between sexual orientation groups on the number of older brothers and older sisters, and this differed depending on handedness. We found no significant differences between sexual orientation groups on measurements of 2D:4D ratio. However, this is likely due to the relatively small sample size. This is the first study to test and provide empirical support for an underlying biological etiology to account for the lack of sexual attraction characteristic of asexuality. Study 2 presents the development of a brief, self-report measure of asexuality. Initial testing of questionnaire items identified by an expert panel was followed by a study aimed at further refining the questionnaire. Based on discriminant analysis as well as reliability and validity tests, a 10-item measure was identified, and was found to be able to distinguish between sexual and asexual individuals. This measure will be used to obtain more representative samples of asexuals in future research.

description: Ziel dieser Studie war es zu prüfen, ob die direkte Ulcussonographie im Diagnosespektrum nutzbringend sein kann und eine genauere Graduierung venöser und arterieller ätiologischer Faktoren ermöglicht. In eine prospektive klinische Studie wurden 69 Patienten (42 weiblich, 27 männlich, Altersmittelwert 75,01 Jahre) mit 78 Ulcera crurum ohne Problemkeimnachweis einbezogen. Die direkte Ulcussonographie ist bei entsprechender Vorbereitung gut praktikabel und für den Patienten wenig belastend. Eine aussagekräftige Refluxdiagnostik in den Ulcusvenen gelang in liegender Position nur unzureichend. Zahlreiche diagnostisch wertvolle morphologische und funktionelle Aspekte konnten darüber hinaus ermittelt werden wie Art und Ausmaß der Gewebe- und Fasziendestruktion, Differenzierbarkeit weicher und indurierter Ödeme durch den Kompressionstest, Erfassung von Abszedierungen im Ulcus und Verdachtsmomente für das Vorliegen einer Vaskulitis oder eines Ulcuskarzinoms. Die direkte Ulcussonographie ist zusätzlich zu der herkömmlichen Diagnostik geeignet, wichtige Informationen zur Ätiologie und zur Graduierung verschiedener Ursachen bei chronischen Unterschenkelgeschwüren beizutragen.
description: The aim of this study was to investigate whether direct ulcer ultrasonography can be a beneficial diagnostic tool, and whether it enables a more precise measurement of venous and arterial aetiological factors. A prospective clinical study enrolled 69 patients (42 female, 27 male, mean age 75.01 years) with 78 ulcers that showed no evidence of the presence of problematic bacteria. With appropriate preparation, direct-on-ulcer ultrasonography is practicable and puts very little strain on the patient. Reflux diagnostics on the ulcerous veins of the supine patients did not yield meaningful results. In addition, numerous diagnostically valuable morphological and functional aspects could be determined, such as the type and extent of tissue and fascia destruction, differentiability of soft and indurated edema through the compression test, detection of abscesses in the ulcer and potential presence of vasculitis or ulcer-carcinoma. Direct-on-ulcer ultrasonography, in addition to conventional diagnostics, is useful in providing important information on the aetiology and grading of various causes of chronic leg ulcers.

description: This presentation will be focused on the Russian faculty of the Defense Language Institute, the military ’s primary language school located in Monterey, California, and established in 1947. The number of Russian teachers over the years has ranged between 100 and 300 at its height during the Reagan years; they came from all three emigrations – post-revolutionary (1920s), post-war (1940s), and late Soviet (1970s-1980s). I will look especially closely at the period between the mid-1950s through the 1970s, which I observed at close range as someone who grew up in that Russian community. Besides describing its overall socio-political and ethnic origins and views, I will focus on some of DLIs most interesting teachers – in their own right or because of their backgrounds – and on the relationship between the three emigrations. Among the teachers were perhaps the best Second Wave poet Nikolai Morshen; major literary scholar Vladimir Markov cultural attaché to the Soviet Union Nikita Moravsky; Voice of America commentator and Russian aristocrat Constantine Grigorovich Barsky, for whom the DLI was merely a stepping stone, as well as former Soviet colonel and Vlasovite general, Sergei Markov, for whom the DLI was their last haven. My perspective on the subject is that of witness (as daughter of one of the teachers) and as someone who has long worked in the field of émigré studies.

Material und Methoden: 49 Meningeome wurden analysiert. Eine polygonale Zielregion wurde in Karten des scheinbaren Diffusionskoeffizienten (ADC) in den Grenzen der Läsion gesetzt. Der normalisierte ADC (NADC) berechnet sich als Quotient ADC Meningeom/ADC weiße Substanz. Der Tumorproliferationsindex wurde in Ki 67 Antigen gefärbten Proben bestimmt. Die Zellzahl wurde als Durchschnitt über 5 Hauptgesichtsfelder gemessen. Ergebnisse: Der mittlere ADC von Grad I Meningeomen ist höher als in Grad II/III (0.96 vs 0.8×10-3 mm2s-1, p=0.04). Grad II/III Tumore zeigen niedrigere NADC Werte als Grad I (1.05 vs 1.26, p<0.05). Die mittlere Zellzahl beträgt 1158.2±333.7, der mittlere Proliferationsindex 4.8±5.1%, Ki 67 ist negativ assoziiert mit ADC (r=-0.45, p=0.001) und NADC (r=-0.4, p=0.002). Zusammenfassung: Grad II/III Tumore zeigen niedrigere ADC/NADC Werte als Grad I (p<0,05). ADC/NADC korreliert negativ mit dem Tumorproliferationsindex.
description: Purpose: To analyze diffusion weighted imaging (DWI) findings of meningiomas and to compare them with tumor grade, subtypes, cell count, and proliferation index. Materials and Methods: 49 meningiomas were analyzed. A polygonal region of interest was drawn on apparent diffusion coefficient (ADC) maps around the margin of the lesion. Normalized ADC (NADC) was calculated as ratio ADC meningioma/ADC white matter. Tumor proliferation index was estimated on Ki 67 antigen stained specimens. Cell density was calculated as average cell count per five high power field. Results: Mean ADC value in grade I meningiomas was higher in comparison to grade II/III tumors (0.96 vs 0.8×10-3 mm2s-1, p=0.04). Grade II/III meningiomas showed lower NADC values in comparison to grade I tumors (1.05 vs 1.26, p<0.05). Mean cell count was 1158.2±333.7. Mean proliferation index was 4.8±5.1%. Ki 67 was negatively associated with ADC (r=-0.45, p=0.001) and NADC (r=-0.4, p=0.002). Conclusions: Grade II/III tumors had statistically significantly lower ADC/NADC values than grade I meningiomas. ADC and NADC values correlated negatively with tumor proliferation index.

There is extensive research on resettlement outcomes for newcomers (Frank, 2013; Guo, 2013; Painter, 2014; Schwartz et al., 2010), including those resettled as refugees (George, 2012; Huijts, et al, 2012; Teixiera & Dias, 2018), but not much is known about what happens to individuals' identity as they settle in the new countries. Given this, I explored identity change in the context of resettlement for this specific class of refugees, by asking the question: How do refugee single mothers from Africa make sense of how their identities have changed or remained the same in the context of settling in Canada? In conducting this study, I was guided by a qualitative research method, Interpretative Phenomenological Analysis (IPA; Smith, Larkin, and Flowers; 2009). Using purposive and snowball sampling, I recruited nine women living in two major urban centres in Alberta, who met criteria for participation. I conducted audio-taped, in-depth, semi-structured interviews with each, in either Kiswahili or English. I translated and transcribed the ones in Kiswahili to English and transcribed the ones in English verbatim. Following this, I analyzed the data according to IPA procedures (Smith et al, 2009). Through this process, I created five super-ordinate themes related to identities that remained the same; that had been lost; that were acquired in resettlement; that might change in the future; and that others might use to describe this population. The findings are explained and discussed in the context of relevant literature. Strengths and limitations of the study are considered as well as implications of the findings for research, policy, and the practice of counselling with this population.

description: Expressions involving the product of the permanent with the (n-1)th power of the determinant of a matrix of indeterminates, and of (0,1)-matrices, are shown to be related to two conjectures that extend the Alon-Tarsi Latin square conjecture to odd dimensions. An identity involving an alternating sum of permanents of (0,1)-matrices is obtained.

description: Die Entscheidung zum Therapieverzicht ist fester Bestandteil moderner Intensivmedizin und wird entweder als Begrenzung oder Abbruch intensivmedizinischer Maßnahmen durchgeführt. Zielstellung der vorliegenden Arbeit war die Untersuchung und Bewertung der Therapieentscheidungen am Lebensende auf der Intensivstation. Dazu wurden Daten von 152 Patienten, die zwischen 2008 und 2010 verstarben, retrospektiv ausgewertet. Hierbei zeigte sich, dass ein höheres Patientenalter, eine schwere akute Erkrankung sowie ein komplikationsreicher Krankheitsverlauf einen signifikanten Einfluss auf die Entscheidung zum Therapieverzicht hatten, während Art der Vorerkrankungen des Patienten sowie das vorliegen schriftlicher Vorausverfügungen nur eine untergeordnete Rolle spielten. Durch die Gesetzesänderung vom 1. September 2009 wurde zwar die Verbindlichkeit der Vorausverfügungen bestärkt, die klinische Interpretation und praktische Umsetzung bleibt davon jedoch im Regelfall unberührt.
description: Limitation of life-sustaining treatment is an integral part of modern intensive care medicine, either as withholding or withdrawing therapy. The aim of the present study was the investigation and evaluation of end-of-life practices in the intensive care unit. Data from 152 patients who died between 2008 and 2010 were retrospectively analyzed. It was shown that a higher patient age, a severe acute diagnosis as well as severe disease progression had a significant influence on end-of-life decisions, while chronic diagnoses and written advance directives only played a minor role. The amendment to the law of 1 September 2009 strengthened the binding nature of the patients’ advance directives, but the clinical interpretation and practical implementation remain unaffected.

description: The presentation will discuss identity challenges, social dynamics, political and religious views and behavior, and prospects of continuing as a distinctive socio-cultural group of the Russian-speaking American Jews who arrived to the US during the last 40 years. In search of their multi-faceted identity, Russian Jews have to cooperate with their American (and Jewish American) counterparts and hosts. Simultaneously, explicitly or implicitly, they attempt to maintain a separation line, a zone where they would feel socially, culturally, religiously, politically, linguistically, and even economically comfortable, relatively independent in their life-style and mindset from their American brethren. The presentation will be using data that was obtained and interpreted by a number of surveys sponsored by the American Jewish Committee (AJC) and other agencies and conducted by Research Institute for New Americans (RINA) during 1998-2012.

description: Ziel dieser Arbeit sind fundierte Abschätzungen über die Ausfallzeitpunkte von PID-anfälligen Solarmodulen in Abhängigkeit von unterschiedlichen Standorten und den dort vorherrschenden klimatischen Bedingungen. Zu diesem Zweck wurde ein iteratives Vorhersagemodell entwickelt, mit dessen Hilfe anhand von Wetterdaten der Ausfallzeitpunkt eines definierten Solarmodulaufbaus berechnet werden kann. Das Vorhersagemodell basiert auf den Ergebnissen der Untersuchung des PID-Effekts in Abhängigkeit von variierenden Umgebungsbedingungen im Labor. Ausgehend von den Ergebnissen wurde iterativ in drei Stufen ein PID-Vorhersagemodell entwickelt. Das Vorhersagemodell erlaubte es, die Ausfallzeit der Proben an verschiedenartigen geographischen Standorten miteinander zu vergleichen. Da die Untersuchungen in dieser Arbeit zum großen Teil auf Ein-Zellen-Minimodulen basieren, wurde abschließend die Übertragbarkeit der Ergebnisse auf handelsüblichen 60-Zellen-Module überprüft.
description: The aim of this work is to provide information about the failure times of PID-susceptible solar modules depending on different locations and the prevailing climatic conditions. For this purpose, an iterative predictive model was developed, which can calculate the failure time of a defined solar module array on the basis of weather data. The predictive model is based on the study of the PID effect as a function of varying ambient conditions in the laboratory. From these results, a PID prediction model was developed iteratively in three stages. The predictive model allows a comparison of the downtimes of the samples at various climatic locations. Since the investigations in this work are largely based on one-cell minimum modules, the transferability of the results to commercial 60-cell modules was finally verified.

description: We describe our ongoing program to measure velocity dependent charge transfer (CT) cross sections for selected ions on atomic hydrogen using the ion-atom merged-beams apparatus at Oak Ridge National Laboratory. Our focus is on those ions for which CT plays an important role in determining the ionization structure, line emission, and thermal structure of observed cosmic photoionized plasmas.

description: Die Roggen Elternlinien ("Stabilstroh" und Wildtyp) und die F2-Population wurden unter Verwendung anatomischer, ultrastruktureller, elementarer und biochemischer Merkmale phänotypisiert, um die genetische Grundlage für die Lagerresistenz in "Stabilstroh" zu ermitteln. Anschließend wurden die Linien mit SSR- und DArTseq-Markern genotypisiert. Die genetische Karte von 7 Chromosomen wurde basierend auf 1042 Markern konstruiert. Diese Karte wurde für die QTL-Kartierung der analysierten Merkmale verwendet, die es ermöglichte, 15 bestimmte Regionen zu finden, die mit Pflanzenhöhe, Länge des zweiten basalen Internodiums, Anzahl der Bestockungen, Trockengewicht der Halme, Anzahl von Stengel-Invaginationen, Dicke von assoziiert waren Halmwand und Sklerchymschicht, Anzahl der inneren Gefäßbündel, Durchmesser der epidermalen und sklerchymalen Zelle und Dicke der sklerchymalen und epidermalen Zellwand. Zusätzlich wurden 7 QTL für den Gehalt an Molybdän, Nickel, Kupfer, Schwefel und Zink bestimmt.
description: The parental lines (‘Stabilstroh’ and wildtype) and segregating F2 population, were phenotyped using anatomical, ultrastructural, elemental, and biochemical traits to detect QTL underlying these characters and to elucidate the genetic basis of the lodging resistance in ‘Stabilstroh’. Subsequently, parental lines and F2 population were genotyped with SSR and DArTseq markers. The genetic map of 7 chromosomes was constructed based on 1042 markers. The obtained linkage map was used for QTL mapping of the analysed traits, which allowed to find 15 determined regions associated with: plant height, length of the second basal internode, number of tillers, dry weight of culms, number of epidermal invaginations, thickness of culm wall and sclerenchymal layer, number of inner vascular bundles, diameter of the epidermal and sclerenchymal cell, and thickness of sclerenchymal and epidermal cell wall. Moreover, 7 QTL were determined for the content of molybdenum, nickel, copper, sulphur, and zinc.

description: We have performed the first energy-resolved measurement of the associative detachment (AD) reaction H- + H → H2 + e-: This reaction is the dominant formation pathway for H2 during the epoch of first star formation in the early universe. Despite being the most fundamental anion-neutral chemical reaction, experiment and theory have failed to converge in both magnitude and energy dependence. The uncertainty in this rate coefficient severely limits our under- standing of the formation of the first stars and protogalaxies.

description: Using magnetization measurements, we show that point defects in graphene - fluorine adatoms and irradiation defects (vacancies) - carry magnetic moments with spin 1/2. Both types of defects lead to notable paramagnetism but no magnetic ordering could be detected down to liquid helium temperatures. The induced paramagnetism dominates graphene's low-temperature magnetic properties despite the fact that maximum response we could achieve was limited to one moment per approximately 1000 carbon atoms. This limitation is explained by clustering of adatoms and, for the case of vacancies, by losing graphene's structural stability.

description: DEBRIS is a flux-limited survey of nearby stars (spectral types A-M) for evidence of debris disks with the Herschel Space Observatory. One goal of the survey is to determine disk incidence as a function of various stellar parameters. Understanding debris disk evolution depends on knowledge of the precise age of stars around which these debris disks are found. However, finding ages for field stars is notoriously difficult. Furthermore, in an unbiased sample like DEBRIS, one is working with stars across many spectral types. This requires a multi-method approach to age determination. In this paper, we outline several methods of age determination broken down by spectral type, including some strengths and limitations of each method. In total, we were able to calculate ages for 263 of 274 F, G, and K-type stars, and all 83 A-type stars in the DEBRIS sample.
