Frequency of C > T polymorphism in fourth chromosome and levels of crp in patients with atrial

Introduction. Atrial fibrillation is a heart rhythm disorder, characterized by rapid and uncoordinated atrial activation which is the most common arrhythmia in clinical practice. Atrial fibrillation is observed in 1.5 - 2% of the general population and its incidence increases with age reaching more than 8-15% by 80 years of age. Atrial fibrillation is traditionally considered as a non genetic disorder. The cause of atrial fibrillation in 10-20% of cases is unknown and it is diagnosed as idiopathic

Quantitative X-ray microanalysis of precipitates in zinc-aluminium-copper

peer reviewedThe aim of the present study is to adapt the Cliff-Lorimer method for quantitative analysis of thin foils and to obtain information about the composition of fine metastable precipitates in Zn-Al-Cu alloys. The coefficients K(al-zn) and K(al-cu) were determined for accelerating voltage of 200 kV, about which there has no been data ever mentioned. Some applications of the method are given

Microstructural study of Zn-Al alloy

It is well known that zinc-aluminium alloys posses very good mechanical properties. This is the reason why the investigation of their ageing characteristics is very important for the practice. Several solid state reactions between alpha, beta, epsilon and T phases have been established for such materials alloyed with copper, but there has been no detailed on the formation, development and transformation of metastable phases into stable ones. This is exactly the aim of our investigation

The place of the virtual dissection table Sectra in anatomy lessons of medical students

Anatomy is a key discipline not only in the field of medical education, but also in the professional development of a young medical doctor. It is the first discipline for every healthcare student when starting his/her training. In this process many students face psychological and pedagogical challenges - a lot of information, difficult knowl­edge reproduction and systematization, first dissection hall and working with corpses. This is an integral part of the classical anatomy training methods - dissection practice. The advances in technology have allowed the devel­opment of new and interactive methods, such as the medical table for virtual dissection Sectra. Different points of view can be demonstrated using some instruments in the 3D dissection of a real human body.Our aim was to evaluate the students` opinion on the new innovative interactive method provided by the virtual dissection table Sectra in dissection practice. During the second semester of practical training in cadaver dissec­tion cycle, we performed a pilot practical exercise using the medical table for virtual dissection Sectra. An anon­ymous questionnaire was given to 50 students to evaluate their impressions and opinions concerning the place of the dissection table in their anatomy education. The students point the classical method for dissections as the main and most effective one, although accompanied by some obstacles. On the other hand they think that the in­novative method is interesting and useful. Most of the students` point that combining the two methods would be the best way to help them understand the information.The classical dissection method has kept its relevance and importance. On the other hand the innovative methods are gaining more popularity and support because of the times we live in. The Sectra table gives us the unique op­portunity to provide basic knowledge of the body, adding more opportunities to the classical method. This com­bination gets the highest evaluation by students and instructors concerning effectiveness and success rate

Contamination in electron observations of the silicon detector on board Cluster/RAPID/IES instrument in Earth's radiation belts and ring current

Since more than 15 years, the Cluster mission passes through Earth’s radiation belts at least once every 2 days for several hours, measuring the electron intensity at energies from 30 to 400 keV. These data have previously been considered not usable due to contamination caused by penetrating energetic particles (protons at >100 keV and electrons at >400 keV). In this study, we assess the level of distortion of energetic electron spectra from the Research with Adaptive Particle Imaging Detector (RAPID)/Imaging Electron Spectrometer (IES) detector, determining the efficiency of its shielding. We base our assessment on the analysis of experimental data and a radiation transport code (Geant4). In simulations, we use the incident particle energy distribution of the AE9/AP9 radiation belt models. We identify the Roederer L values, L⋆, and energy channels that should be used with caution: at 3 ≤ L⋆ ≤ 4, all energy channels (40–400 keV) are contaminated by protons (≃230 to 630 keV and >600 MeV); at L⋆ ≃1 and 4–6, the energy channels at 95–400 keV are contaminated by high-energy electrons (>400 keV). Comparison of the data with electron and proton observations from RBSP/MagEIS indicates that the subtraction of proton fluxes at energies ≃ 230–630 keV from the IES electron data adequately removes the proton contamination. We demonstrate the usefulness of the corrected data for scientific applications
