Influence of Systematic Errors on the Electron Density and Temperature Measured with Thomson Scattering at W7-X
Suggesting a New European Language Policy
Conflict is the most intriguing aspect of contact linguistics. Throughout history ever
since the Tower of Bable was left unfinished, contacts between speakers of different languages
have unavoidably resulted in conflicts between speakers of those languages. Without
any doubt, the European Union (EU) – above all after the decision to enlarge the
community – has accepted the multidisciplinary symbolic function of language and culture
as a basis for European political unification. Accordingly, European Union policy
makers have had to analyze conflicts caused by monolingualism and multilingualism,
all aspects of contact linguistics. Can these conflicts be solved, minimized or neutralized
by strategies of language planning, language policies and language politics? Initial results
of European language policy strategies permit at least a cautious measure of optimism
and open broad perspectives for the future of a New Multilingualism which will
be discussed in our contribution

KONSEP AKSESBILITAS DAN VEGETASI PADA TAMAN BERMAIN ANAK DIFABEL DI SLB-C LAWANG
Person with disabilities has different needs than normal individuals. This difference causes limitations in movement and orientation. As a designer, of course in creating facilities can be used all levels of society, so the need for special treatment in design. Part of architectural context other than buildings is open space. Open space has another function, as a circulation path can also be developed in the form of park. Benefits for people with disabilities, parks can also be a means of learning, training independence and therapeutic areas. In the case study selected location in SLB-C Lawang (tuna grahita or mental retardation), this location has a large area for the development of garden design of motor development and mental children with disabilities or called educational park. The park is divided into two zones: active and passive. The active zone consists of a children's playroom and a sensory park that trains the senses of the five senses, while the passive zone as a park to be visually enjoyed. Therapeutic activities for mental retardation are not just for healing but to practice the senses' abilities of smell, taste, touch, and listener. Initially still an open space that has not been functioned specifically. The problem in this research is how the concept of accessibility and vegetation so that facilities can be used. The objective of the study was to develop a system in parks that can be enjoyed by people with disabilities and as a means of therapy. The result of this research is a concept of ease of achievement of garden for children with disfigured attention to detail of circulation design and variety of vegetation that support the concept of sensory garden so as therapy area

Immunoprecipitation methods impact the peptide repertoire in immunopeptidomics
IntroductionMass spectrometry-based immunopeptidomics is the only unbiased method to identify naturally presented HLA ligands, which is an indispensable prerequisite for characterizing novel tumor antigens for immunotherapeutic approaches. In recent years, improvements based on devices and methodology have been made to optimize sensitivity and throughput in immunopeptidomics. However, developments in ligand isolation, mass spectrometric analysis, and subsequent data processing can have a marked impact on the quality and quantity of immunopeptidomics data.MethodsIn this work, we compared the immunopeptidome composition in terms of peptide yields, spectra quality, hydrophobicity, retention time, and immunogenicity of two established immunoprecipitation methods (column-based and 96-well-based) using cell lines as well as primary solid and hematological tumor samples.ResultsAlthough, we identified comparable overall peptide yields, large proportions of method-exclusive peptides were detected with significantly higher hydrophobicity for the column-based method with potential implications for the identification of immunogenic tumor antigens. We showed that column preparation does not lose hydrophilic peptides in the hydrophilic washing step. In contrast, an additional 50% acetonitrile elution could partially regain lost hydrophobic peptides during 96-well preparation, suggesting a reduction of the bias towards the column-based method but not completely equalizing it.DiscussionTogether, this work showed how different immunoprecipitation methods and their adaptions can impact the peptide repertoire of immunopeptidomic analysis and therefore the identification of potential tumor-associated antigens
Quantification of systematic errors in the electron density and temperature measured with Thomson scattering at W7-X
The electron density and temperature profiles measured with Thomson
scattering at the stellarator Wendelstein 7-X show features which seem to be
unphysical, but so far could not be associated with any source of error
considered in the data processing. A detailed Bayesian analysis reveals that
errors in the spectral calibration cannot explain the features observed in the
profiles. Rather, it seems that small fluctuations in the laser position are
sufficient to affect the profile substantially. The impact of these
fluctuations depends on the laser position itself, which, in turn, provides a
method to find the optimum laser alignment in the future
Mega-dose vitamin C attenuated lung inflammation in mouse asthma model
Asthma is a Th2-dependent disease mediated by IgE and Th2 cytokines, and asthmatic patients suffer from oxidative stresses from abnormal airway inflammation. Vitamin C is a micro-nutrient functioning as an antioxidant. When administered at a mega-dose, vitamin C has been reported to shift immune responses toward Th1. Thus, we tried to determine whether vitamin C exerted beneficial effects in asthma animal model. Asthma was induced in mice by sensitizing and challenging with ovalbumin. At the time of challenge, 3~5 mg of vitamin C was administered and the effects were evaluated. Vitamin C did not modulate Th1/Th2 balance in asthma model. However, it decreased airway hyperreactivity to methacholine, decreased inflammatory cell numbers in brochoalveolar lavage fluid, and moderate reduction of perivascular and peribronchiolar inflammatory cell infiltration. These results suggest that vitamin C administered at the time of antigen challenge exerted anti-inflammatory effects. Further studies based on chronic asthma model are needed to evaluate a long-term effect of vitamin C in asthma. In conclusion, even though vitamin C did not show any Th1/Th2 shifting effects in this experiment, it still exerted moderate anti-inflammatory effects. Considering other beneficial effects and inexpensiveness of vitamin C, mega-dose usage of vitamin C could be a potential supplementary modality for the management of asthma
