Opis:
We studied the shell and penis morphology, and cytochrome oxidase subunit I (COI) gene sequences, in minute, valvatiform hydrobiid gastropods from Slovensky Kras, Slovakia. The morphology confirmed the assignment of the studied snails to the genus Hauffenia, while in the molecular tree they were placed within the Hydrobiidae, and not close to Hauffenia. The results indicate that the Slovak valvatiform hydrobiids are two taxa which presumably represent two genera: Hauffenia Pollonera, 1898 and Lobaumia Haase, 1993. More molecular data on the Austrian and Hungarian taxa are needed.

Opis:
The overall objective of the IDEAS project is to develop advanced packaging for power supply components and new generation memory systems applicable to Electric and ICE propelled vehicles, with paying attention to considering also the aspects that have not been addressed yet in the running ENIAC and ARTEMIS Automotive projects. A major challenge related to electronic devices in the automotive applications is the reliability of power supply systems which must be capable to assure the functionality of subsystems in all operating conditions, inclusive of ageing. The control systems, which rely on multicore microcontrollers and complex software architectures, require increasingly stringent constraints from the memory devices which need to be designed for very high bandwidth, speed and reliability. In the following thesis, a few aspects of the IDEAS project will be presented: a review of important factors that affect the reliability and life-cycle endurance of NAND flash memories, multispeed gear application in electric drives and its influence on the energy efficiency. The problem of electromagnetic compatibility of electronic devices will also be dealt with in the paper

Opis:
Current engine technology for on-road vehicles allows us to meet the existing and planned future standards for emission. Because combustion engines, especially self-igniting are being used for very different purposes like: road transport, rail-way transport, shipping, industry, military and agriculture, these engines work in different and often difficult conditions. A very significant group of vehicles used for the most difficult of the a forementioned areas ofuse are "Off-Road" vehicles. For those vehicles we also use rigorous regulations to govern dangerous chemical emissions such as Tier, Bin and Californian LEV. In those types of vehicles the fuel powered systems very often use mechanically controlled diesel injection pump. These pumps are characterized by high tolerance to the quality and type ofpetrol as well as reliability, which is very important especially in "off-road" vehicles. At work a conception was described of system of powering the engine diesel which will let for reaching of future emission exhaust quality standards. In the paper only initial outline of the idea of the injection 's system for „off-road" vehicles, is introduced. This system needs follow-on in the field both interactions with the EGR valve, with the injection 's system as well as in the matter of interaction with ECU of the injection 's system.

Opis:
The results of the investigation of magnetic susceptibility, magnetization and specific heat of $Cu_3(tmen)_3(tma)_2(H_2O)_2$ · $6.5H_2O$ (tmen = N,N,N',N'-tetramethylethane-1,2 diamine; $H_3$ tma = 1,3,5-benzenetricarboxylic acid) are reported. The spatial arrangement of magnetic Cu(II) ions and network of covalent bonds suggest that the studied material might be a representative of S = 1/2 sawtooth chain with moderate exchange coupling J/$k_{B}$. The investigation of the temperature dependence of susceptibility and magnetic field dependence of magnetization yielding J/$k_{B}$ ≈ - 0.63 K is consistent with the structural features. In addition, specific heat data reveal short-range correlations in milikelvin temperature range and indicate long-range ordering below 150 mK.

Opis:
Magnetic susceptibility and X-band electron spin resonance study of a two-dimensional Heisenberg antiferromagnetic system $CuBr_2$(bipy), where bipy = $C_{10}H_8N_2$ is 4,4'-bipyridyl, has been performed in the temperature range from 300 K down to 2 K. A rhombic anisotropy of the g-factor was obtained from X-band EPR measurements with $g_{x}$ = 2.037, $g_{y}$ = 2.100 and $g_{z}$ = 2.219. The temperature dependence of the magnetic susceptibility with a round maximum observed at 28 K suggests antiferromagnetic type of short-range order. No signature of the magnetic long-range order in studied compound was observed. The comparison of the magnetic susceptibility data with a two-dimensional rectangular Heisenberg model yields the values of intralayer exchange couplings J/$k_{B}$ = - 47 K and J'/$k_{B}$ = - 9.4 K.

Opis:
"Elaioplasts" observed in Vanilla planifolia, Funkia Sieboldiana and Althaea rosea exhibit all the features characteristic of lipotubuloids earlier described in Ornithogalum umbellatum. They are cytoplasmic domains containing aggregates of lipid bodies connected with microtubules. The immunogold technique confirmed the presence of tubulin in this domain. These structures do not have their own membranes but they are surrounded by a tonoplast at the side of a vacuole since they invaginate into it. In cytoplasm of this domain among lipid bodies there are numerous ribosomes, ER cisternae and vesicles as well as few mitochondria, Golgi structures and microbodies while at older developmental stages there are also autolytic vacuoles. The fact that they are so similar to O. umbellatum lipotubuloids suggest that "elaioplasts" of V. planifolia, F. Sieboldiana and A. rosea can also be named lipotubuloids.

Opis:
Recent concepts of discrete curvatures are very important for Medical and Computer Aided Geometric Design applications. A first reason is the opportunity to handle a discretisation of a continuous object, with a free choice of the discretisation. A second and most important reason is the possibility to define second-order estimators for discrete objects in order to estimate local shapes and manipulate discrete objects. There is an increasing need to handle polyhedral objects and clouds of points for which only a discrete approach makes sense. These sets of points, once structured (in general meshed with simplexes for surfaces or volumes), can be analysed using these second-order estimators. After a general presentation of the problem, a first approach based on angular defect, is studied. Then, a local approximation approach (mostly by quadrics) is presented. Different possible applications of these techniques are suggested, including the analysis of 2D or 3D images, decimation, segmentation... We finally emphasise different artefacts encountered in the discrete case.

Opis:
In this study the scaffolds for nasal cartilages replacement were designed using a software called Rhino 3D v5.0. The software parameters considered for the design of scaffolds were chosen and the scaffolds were fabricated using Fused Deposition Modeling (FDM), a rapid prototyping technology, using poly(L-lactic acid) (PLLA) filament. The topographical properties of the scaffolds were calculated through 3D model simulation. The morphology of obtained scaffold was observed by Scanning Electron Microscopy (SEM). The biological properties, i.e. bioactivity of the scaffolds, were assessed in Simulated Body Fluid. On the basis of natural cartilages images the external shape of the scaffold was designed using the 3D modeling software. The FDM is a useful method in fabrication of 3D bioactive implants for cartilage tissue engineering. Thanks to the use of 3D modeling software, it is possible to prepare and manufacture artificial cartilage in a controlled manner. Artificial scaffold made of PLLA polymeric matrix may mimic natural one by shape, topography, geometry, pore size, and their distribution. In addition, it is possible to guarantee appropriately selected biological properties such as biocompatibility and high bioactivity of scaffolds, which was proved using scanning electron microscopy (SEM) analysis. The surface observation of the 3D printed scaffolds showed in vitro formation of apatite after immersion in the SBF. What is more, it is possible to match the scaffold not only to the large cavity but also individually to each patient.

Opis:
5-Hydroxymethylfurfural (HMF) was determined with HPLC method in forty one food samples, including gluten-free, breakfast cereals and bakery products. The highest concentration of HMF was found in wheat bread with cranberries (210 mg kg-1) and in breakfast cereals – honey wheat loops (85.099 mg kg-1). In contrast, wholegrain oatmeal and gluten-free sponge cakes had the lowest HMF level of all tested samples, below the detection limit and 0.485 mg kg-1, respectively. In most cases, lack of gluten coincided with the lowest HMF content readings (average 8.488 mg kg-1). The impact of the type of sugar, especially glucose, on the HMF concentration in food is apparent. Sweetened breakfast cereals, with the average content of HMF at 25.55 mg kg-1, took lead over dietary products (8.488 mg kg-1) and bakery products (18.395 mg kg-1), with the exception for wheat bread with cranberries. These cereals contained glucose or glucose-fructose syrup.
