In the ILD concept, a TPC is foreseen as the main tracking device. The MediTPC prototype has been developed at DESY to study the properties of Gas Electron Multipliers (GEMs) and to perform resolution studies. Studies of the influence of oxygen contaminations on the electron signal are presented here. Further, resolution results with new pad planes with 1.27 × 7.0mm pad pitch and in high magnet...

The problem of robustifying of the sequential probability ratio test is considered for a discrete hypothetical model. Exact values for error probabilities and for conditional expected sample sizes are obtained. Asymptotic robustness analysis for these characteristics is performed under “contaminations”. A two-parametric family of modified sequential probability ratio tests is proposed and analy...

Based on previous researches and current research indoor contaminations in most of the time were more than outdoor contaminations. In according to, most of our times have been spent in indoor environments (85-90%), therefore, it is necessary to investigate indoor environments. Symptoms of sick building syndrome are Headache, dizziness, drowsiness. Unknown reasons of disease above mentioned and ...

BACKGROUND AND OBJECTIVES Glass ampoules have been widely used in packaging injection drugs. Glass has important characteristics that allow it to be widely used in fabrication of recipients for drugs and other sterile substances. However, contamination of solutions with glass microparticles on breaking open glass ampoules, the presence of metals, percutaneous injury, and biological contaminatio...

This note covers three topics in the study of identified hadrons and jet production, coming from recent analyses by the DELPHI experiment at LEP. A description of DELPHI can be found in [1]; its performance is discussed in [2]. The selection of qq̄ events at the Z peak (LEP 1) is easy: being the production of hadronic final states enhanced by three orders of magnitude over the continuum, simple ...

The present study describes approaches for the identification of individual beech trees using maternal tissues from their seeds or fruits. Four microsatellite markers were used for genetic analysis of seedlots from Fagus orientalis Lipsky, a highly out-crossing tree species. Seeds from 11 single-tree harvests belonging to one population, (7 seeds from each), as well as non-paranchymatic materna...

Thinning out MoS2 crystals to atomically thin layers results in the transition from an indirect to a direct bandgap material. This makes single layer MoS2 an exciting new material for electronic devices. In MoS2 devices it has been observed that the choice of materials, in particular for contact and gate, is crucial for their performance. This makes it very important to study the interaction be...

Abiotic stresses such as salinity and metal contaminations are the major environmental stresses that adversely affect crop productivity worldwide. Crop responses and tolerance to abiotic stress are complex processes for which "-omic" approaches such as metabolomics is giving us a newest view of biological systems. The aim of the current research was to assess metabolic changes in lettuce (Lactu...

The issue of non-Gaussianity is not only related to distinguishing the theories of the origin of primordial fluctuations, but also crucial for the determination of cosmological parameters in the framework of inflation paradigm. We present an advenced method for testing non-Gaussianity on the whole-sky CMB anisotropies. This method is based on the Kuiper’s statistic to probe the two-dimensional ...
