The Orphic Hymns consist of a prooemium and 87 hymns addressed to several deities in a late Orphic initiation of sorts. They were composed probably in Asia Minor during the second or third century CE. The bulk of these hymns are made up of divine epithets often linked together in chains of considerable length. The lexicon attempts to give a comprehensive account of the roughly 850 epithets, bringing together the most relevant information scattered in the scholarly literature and adding others from various sources (literary, epigraphic, lexicographic, scholia etc.) in order to provide an overview of their usage and the main details of their models.
The goal of the project was to establish knock down of mRNA in human mesenchymal stem cells. Since these cells are difficult to transfect, a viral approach is needed to achieve sufficient expression of e. g. shRNA in a high percentage of cells to allow for an efficient silencing of corresponding mRNAs. For this purpose for every gene product of interest, a number of shRNA clones have to be tested to detect an individual shRNA with sufficient efficacy. Lentiviral systems for shRNA approaches have recently become available. The principal advantage of the lentiviral system is that it allows gene silencing in nondividing cells and therefore expands the usefulness of the RNAi-based gene silencing system. Lentivirus-delivered shRNAs are capable of specific, highly stable and functional silencing of gene expression in a variety of cell types. Since the viral transfection of MSCs is a time consuming process that involves transfection of 293 FT cells plus transduction of target cells, for this thesis the following approach was chosen: genes of interest were checked for expression in 293FT cells by RT-PCR. These gene products can be silenced in 293FT cells simply by transfection of shRNA clones and efficacy was subsequently tested by RT-PCR. Beyond this thesis then the project can proceed with effective clones to transduce primary MSCs with individual shRNA clones identified as effective silencing tool in this thesis.
TERRAINS OF CONSCIOUSNESS emerges from an Indian-German-Swiss research collaboration. The book makes a case for a phenomenology of globalization that pays attention to locally situated socioeconomic terrains, everyday practices, and cultures of knowledge. This is exemplified in relation to three topics:
- the tension between ‘terrain’ and ‘territory’ in Defoe’s ‘Robinson Crusoe’ as a pioneering work of the globalist mentality (chapter 1)
- the relationship between established conceptions of feminism and the concrete struggles of women in India since the 19th century (chapter 2)
- the exploration of urban space and urban life in writings on India’s capital – from Ahmed Ali to Arundhati Roy (chapter 3).
This volume brings together several authors from different areas of psychology and the neighbouring social sciences. Each one contributes their own perspective on the growing interest topic of subjective well-being. The aim of the volume is to present these divergent perspectives and to foster communication between the different areas. Split into three parts, this volume initially discusses the general perspectives of subjective well-being and addresses fundamental questions, secondly it discusses the dynamics of subjective well-being and more specific research issues to give a better understanding of the general phenomenon, and thirdly the book emphasizes the social context in which people experience and report their happiness and satisfaction. The book will be of great interest to social and clinical psychologists, students of psychology and sociology and health professionals.
Studies in Modern English
(2022)
The book "Studies in Modern English" interprets English-language communication in the humanitarian paradigm of knowledge within the linguistic and psycho-sociocultural study of speech activity prioritizing cognitive and communicative paradigms. Digital discourse as the formation of new semiotic phenomena has crowned the rapid scientific and technological progress. Researchers' scientific achievements represented in the book are systemic and valid in terms of evidence-based narratives, which reflect the transformational horizon of information theory, communication theory, and theory of linguodidactics in modern English verbal, creative and digital environments. The book represents an integrated approach to the study of modern English as an open synergetic system, which requires a description of the relationship between verbal and nonverbal notions in digital space. The book integrates such innovative perspectives as the interaction of natural English and programming languages, cyber aggression as a communicative pattern in English-language digital discourse, ethics, and democratization of modern English language, relevant developments in the field of English language as a Foreign Language, and other related issues. A complex focus of the book in the realm of modern English-language communication concerns verbal and nonverbal notions analyzed in the context of socio-cultural and digital communicative spaces.
This textbook provides an introduction to common methods of performance modeling and analysis of communication systems. These methods form the basis of traffic engineering, teletraffic theory, and analytical system dimensioning. The fundamentals of probability theory, stochastic processes, Markov processes, and embedded Markov chains are presented. Basic queueing models are described with applications in communication networks. Advanced methods are presented that have been frequently used in recent practice, especially discrete-time analysis algorithms, or which go beyond classical performance measures such as Quality of Experience or energy efficiency. Recent examples of modern communication networks include Software Defined Networking and the Internet of Things. Throughout the book, illustrative examples are used to provide practical experience in performance modeling and analysis.
Target group: The book is aimed at students and scientists in computer science and technical computer science, operations research, electrical engineering and economics.
The aim of the book is to ground the logical origins of consciousness in what I have previously called the ‘minimal self’. The idea is that elementary forms of consciousness are logically dependent not, as is commonly assumed, on ownership of an anatomical brain or nervous system, but on the intrinsic reflexivity that defines minimal selfhood. The book seeks to trace the logical pathway by which minimal selfhood gives rise to the possible appearance of consciousness. It is argued that in specific circumstances it thus makes sense to ascribe elementary consciousness to certain predatory single-celled organisms such as amoebae and dinoflagellates as well as to some of the simpler animals. Such an argument involves establishing exactly what those specific circumstances are and determining how elementary consciousness differs in nature and scope from its more complex manifestations.
Surveys by the Universities of Wuerzburg and Berlin, starting in the 1970´s have revealed the existence of palaeolakes in remote areas in Niger. Initial research has shown that the sediments found are suitable for reconstructing its late quaternary palaeoenvironment. Although a high number of investigations focused on the succession of climatological conditions in the Central Sahara, some uncertainties still exist as the results show discontinuities and mostly are of low temporal and spatial
resolution.
Two expeditions in 2005 and 2006 headed to the northeastern parts of Niger to investigate the known remains of palaeolakes and search some new and undetected ones. Samples were taken at several study sites in order to receive a complete picture of the Late Quaternary environmental settings and to produce high-resolution proxies for palaeoclimate modelling.
The most valuable and best-investigated study site is the sebkha of Seggedim, where a core of 15 meters length could be extracted which revealed a composition of high-resolution sections. Stratigraphical, structural and geochemical investigations as well as the analysis of thin sections allow the characterization of different environmental conditions from Early to Mid Holocene. Driven by climate and hydrogeological influence, the water body developed from a water pond of several metres depth within a stable, grass and shrub vegetated landscape, to an alternating freshwater lake in a more dynamic environmental setting. Radiocarbon dates set the beginning of the stage at about 10.6 ka cal BP, with an exceptionally stable regime to 6.6 ka cal BP (at 12.6 metres’ depth), when a major change in the sedimentation regime of the basin is recorded in the core. Increased erosion, likely due to decreased vegetation cover within the basin, led to the siltation/filling of the lake within a few hundred years and the subsequent development of a sebkha/salt pan due to massive evaporation. Due to the lack of dateable material in the upper core section, the termination of the lake stage and the onset of the subsequent sebkha stage cannot be determined precisely but can be narrowed to a period around 6 ka BP.
The results obtained from the core are compared with those from terrestrial and lacustrine sediments from outside the depression, situated a few hundred kilometres further to the north. These supplementary study sites are required to validate the information obtained from the coring. Within the plateau landscape of Djado, Mangueni and Tchigai, two depressions and a valley containing lacustrine deposits, were investigated for palaeoenvironmental reconstruction. Depending on modifying local factors, these sediment archives were of shorter existence than IX the lake, but reveal additional information about the landscape dynamics from Early to Mid Holocene.
A damming situation within a small tributary at Enneri Achelouma led to lacustrine sedimentation conditions at Early Holocene in the upper reaches of the valley. The remnants of the lacustrine accumulations show distinct changes in the environmental conditions within the small catchment, as the archive immediately responded to local climate-induced changes of precipitation. Radiocarbon dating of the deposited sediments revealed ages from 8780 ± 260 cal a BP to 9480 ± 80 cal a BP.
The sites of Yoo Ango and Fabérgé show a completely different sedimentation milieu as they consist of basins within the foothills of the Tchigai. The study sites show increased catchment sizes, probably extending towards the Tchigai massif and are most likely influenced by groundwater charge. The widespread occurrence of wind shaped relicts and the limited amount of lacustrine remnants indicate a generally high aeolian activity in both areas. Only in wind sheltered spots, parts of the lacustrine sequences were preserved, that show ages spanning from Early to Mid Holocene (9440 ± 140 cal a BP – 6810 ±140 cal a BP) and give additional evidence of fires from pre-LGM periods. Although intensively weathered, all profiles indicate distinct changes in the sedimentation conditions by alternating geochemical values and the mineralogical composition.
The information obtained from the records investigated in this work confirms the heterogeneity of reconstructed environmental succession in the Central Sahara. The Mid Holocene rapid (within decades) and uniform development from more humid to extremely arid environmental conditions cannot be confirmed for the Central Sahara. In addition, a division of Early and Mid Holocene wet periods cannot be confirmed, either. Actually, the evidences obtained from the palaeoenvironmental reconstructions revealed major variations in the timing and extend of lacustrine and aeolian periods. Evidently, a transitional time has existed between 7 to 5 ka BP where alternating influences prevailed. This is indicated by the varying sedimentation conditions in the Seggedim depression as well as the evidence of soil properties on a fossil dune, with a time of deposition dated to 6200 ± 400 cal a BP and the removal of lacustrine Sediments at the Seeterrassental at Mid Holocene. In respect to provide a complete picture of landscape succession and to avoid misinterpretation, the investigation of several dissimilar spots within a designated study area is prerequisite for further investigations.

The cluster of texts assembled here were imagined, crafted, and brought together as a collaborative writing project that emerged from the seminar titled "Words Matter Worlds: Activist Scholarship and Literary Praxis," which convened over the course of the 2021/22 winter semester as an offering of the American Studies department of the Julius-Maximilians-Universität Würzburg. Like the seminar that nurtured the considerations that evolve here, these contributions engage with how scholarly writing practices in general, and literary and cultural studies in particular, can remake the world.
For a large fraction of the proteins expressed in the human brain only the primary
structure is known from the genome project. Proteins conserved in evolution can
be studied in genetic models such as Drosophila. In this doctoral thesis monoclonal
antibodies (mAbs) from the Wuerzburg Hybridoma library are produced and
characterized with the aim to identify the target antigen. The mAb ab52 was found
to be an IgM which recognized a cytosolic protein of Mr ~110 kDa on Western
blots. The antigen was resolved by two-dimensional gel electrophoresis (2DE) as a
single distinct spot. Mass spectrometric analysis of this spot revealed EPS-15
(epidermal growth factor receptor pathway substrate clone 15) to be a strong
candidate. Another mAb from the library, aa2, was already found to recognize
EPS-15, and comparison of the signal of both mAbs on Western blots of 1D and
2D electrophoretic separations revealed similar patterns, hence indicating that both
antigens could represent the same protein. Finally absence of the wild-type signal
in homozygous Eps15 mutants in a Western blot with ab52 confirmed the ab52
antigen to be EPS-15. Thus both the mAbs aa2 and ab52 recognize the Drosophila
homologue of EPS-15. The mAb aa2, being an IgG, is more suitable for
applications like immunoprecipitation (IP). It has already been submitted to the
Developmental Studies Hybridoma Bank (DSHB) to be easily available for the
entire research community.
The mAb na21 was also found to be an IgM. It recognizes a membrane associated
antigen of Mr ~10 kDa on Western blots. Due to the membrane associated nature
of the protein, it was not possible to resolve it by 2DE and due to the IgM nature of
the mAb it was not possible to enrich the antigen by IP. Preliminary attempts to
biochemically purify the endogenously expressed protein from the tissue, gave
99
promising results but could not be completed due to lack of time. Thus
biochemical purification of the protein seems possible in order to facilitate its
identification by mass spectrometry. Several other mAbs were studied for their
staining pattern on cryosections and whole mounts of Drosophila brains. However,
many of these mAbs stained very few structures in the brain, which indicated that
only a very limited amount of protein would be available as starting material.
Because these antibodies did not produce signals on Western blots, which made it
impossible to enrich the antigens by electrophoretic methods, we did not attempt
their purification. However, the specific localization of these proteins makes them
highly interesting and calls for their further characterization, as they may play a
highly specialized role in the development and/or function of the neural circuits
they are present in. The purification and identification of such low expression
proteins would need novel methods of enrichment of the stained structures.
Can cultural studies attend to the problems of our globalized world? Or is this project of “engaged scholarship” too deeply rooted in the parochial terrain of the national?
This collection of essays – the first volume in the new JMU Cultural Studies publication series – attends to this vital yet difficult question. Based on joint seminars bringing together emerging scholars from Germany and India, the contributions confront “classic texts” from US-American, British, and Indian cultural studies with the specific concerns and contemporary perspectives of the authors.
The collection thus tests the potentials of the tradition to speak to the transnational as well as the national environments of the very present. Emphasis is placed on Marxist and feminist legacies, which are then projected into the domains of contemporary disability, food, and film studies.
The need for mental health support within the Parkinson’s disease (PD) community has never been greater, yet many practitioners lack the knowledge or experience to address the unique challenges associated with PD. This book serves as a practical guide for mental health professionals to assist individuals with PD and caregivers through the use of cognitive-behavioral therapy techniques, with the goal of enhancing their well-being and quality of life. The book includes a review of information about PD and mental health, and four structured group programs designed to address issues that are common in people with PD and caregivers:
• Coping with stress and illness
• Communicating about PD
• Emotional expression in PD
• Interventions for caregivers
The programs presented in this book can be utilized as they are, personalized for individual use, or adapted for research protocols. Additionally, the information can serve as a valuable resource for people with PD and their family members, who can learn about PD and be introduced to evidence-based strategies that can be used conjointly with professionals to improve their experience of living with PD.
The analysis of real data by means of statistical methods with the aid of a software package common in industry and administration usually is not an integral part of mathematics studies, but it will certainly be part of a future professional work. The present book links up elements from time series analysis with a selection of statistical procedures used in general practice including the statistical software package SAS. Consequently this book addresses students of statistics as well as students of other branches such as economics, demography and engineering, where lectures on statistics belong to their academic training. But it is also intended for the practician who, beyond the use of statistical tools, is interested in their mathematical background. Numerous problems illustrate the applicability of the presented statistical procedures, where SAS gives the solutions. The programs used are explicitly listed and explained. No previous experience is expected neither in SAS nor in a special computer system so that a short training period is guaranteed. This book is meant for a two semester course (lecture, seminar or practical training) where the first three chapters can be dealt within the first semester. They provide the principal components of the analysis of a time series in the time domain. Chapters 4, 5 and 6 deal with its analysis in the frequency domain and can be worked through in the second term. In order to understand the mathematical background some terms are useful such as convergence in distribution, stochastic convergence, maximum likelihood estimator as well as a basic knowledge of the test theory, so that work on the book can start after an introductory lecture on stochastics. Each chapter includes exercises. An exhaustive treatment is recommended. Chapter 7 (case study) deals with a practical case and demonstrates the presented methods. It is possible to use this chapter independent in a seminar or practical training course, if the concepts of time series analysis are already well understood. This book is consecutively subdivided in a statistical part and an SAS-specific part. For better clearness the SAS-specific parts are highlighted.
