Opis:
The most common public health problems include, among others, overweight, obesity, and cardiovascular diseases. In addition, the number of people with thyroid disturbances is still growing. Thyroid abnormalities can lead to many metabolic dysfunctions, including secondary osteoporosis, alterations in body mass, lipid profile, and insulin resistance. Recently, the studies have been focused on the connections between thyroid gland function, obesity, metabolic syndrome and cardiovascular diseases, as well as bone turnover. Fatty tissue plays an important role in whole body homeostasis. Adipose tissue hormones, such as leptin, resistin and adiponectin are proteins having immunomodulatory lproperties, and their balance is needed to control immune response, as well as inflammation processes. The following article constitutes a review of literature concerning thyroid function with regard to adipocytokines and vitamin D, as well as the influence of this gland on the skeletal system. For this purpose, Medline Pub Med base and Google Scholar were used. All the citied studies in this review article underline how much should be done to achieve more efficient treatment of thyroid disorders, specifically, how to prevent its complications, for instance, osteoporosis, over-weight, obesity or cardiovascular diseases.

Opis:
The semi-isolating GaAs (100) samples irradiated with fluence 3 × $10^{15}$ ions/$cm^{2}$ of $In^{+}$ ions were characterized by using the methods: Rutherford backscattering spectroscopy, nuclear reaction analysis and ellipsometric spectroscopy. The values of the thicknesses layers enriched with oxygen and the implanted were determined by the methods of nuclear reaction analysis and Rutherford backscattering spectroscopy. Multilayer models were applied for determination of the optical constants (refraction and extinctions coefficients) of investigated samples. The thickness of native oxide covering the surface of implanted GaAs and refraction coefficients were increased after implantation with indium. The spectrum of extinction indexes as a function of light wavelength has two bands near the light wavelengths 400 nm and 480 nm. The observed effects can be interpreted as formation of local oxides of In and InAs precipitates or ternary alloys in enriched with oxygen layers at the surfaces of implanted GaAs.

Opis:
This article focuses on the development of architecture and technical solutions for implementation intelligent transport systems (ITS). The presented system will perform the following functions: monitoring the movement of an object collecting and displaying information about the state of the road, warning of the approaching object to obstacles, routing, as well as control of movement and speed of the output parameters of the recommendations of the movement, the development of intelligent decisions about the choice of optimal routes, intellectual analysis of data (IAD) of the style and movement of the driver (the influence of alcohol), IAD on the technical parameters of the vehicle. Thus, it is advisable for ITS to be divided into several subsystems, which are related but are responsible for one or more functional tasks. Consequently, the need for monitoring the movement subsystem, the database on the state of the object database on the location of an object, display subsystem, the subsystem of control of the road, the engine safety (prevention of obstacles), the subsystem control parameters of movement, routing subsystem.
Статья посвящена разработке архитектуры и технических решений для реализации интеллектуальных транспортних систем. Представляемая система будет выполнять следующее функции: мониторинг движения объекта, сбор и отображение информации о состоянии дороги, предупреждение о приближении объекта к препятствиям, маршрутизация, а так же контроль скорости движение и вывод рекомендаций о параметрах движения, разработка интеллектуальных решений о выборе оптимальных маршрутов, интеллектуальном анализе данных (ИАД) о стиле и движении водителя (влиянию алкоголя), ИАД о технических параметрах транспортного средства. Таким образом, целесообразно ITS разделить на несколько подсистем, которые будут взаимосвязаны, но отвечают за одну или несколько функциональных задач. Для реализации этих функций, необходима подсистема мониторинга движения, база данных о состоянии объекта, база данных о местоположении объекта, подсистема отображения информации, подсистема контроля дороги, подсистема безопасности движения (предупреждения о препятствиях), подсистема контроля параметров движения, подсистема маршрутизации.

Opis:
Two analytical methods, atomic force microscopy and quartz crystal microbalance, were applied to the study of the reaction kinetics occurring between concanavalin A and carboxypeptidase Y, presenting the specific lectin-carbohydrate recognition. The dissociation rate constants for concanavalin A-carboxypeptidase Y complex obtained using both atomic force microscopy and quartz crystal microbalance were of the same order of magnitude: k$\text{}_{diss}$=0.170± 0.060 s$\text{}^{-1}$ and k$\text{}_{diss}$=0.095±0.002 s$\text{}^{-1}$, respectively. In addition, each method alone aided in determining other parameters characterizing the studied interaction. Quartz crystal microbalance permitted us to estimate the association rate (k$\text{}_{ass}$=(5.6 ±0.1)×10$\text{}^{4}$ M$\text{}^{-1}$ s$\text{}^{-1}$) and the equilibrium (K$\text{}_{a}$=(0.59×0.01)×10$\text{}^{6}$ M$\text{}^{-1}$) constants for the binding process occurring between concanavalin A and mannose residues of carboxypeptidase Y under given experimental conditions. Atomic force microscopy in force spectroscopy mode enabled the determination of the energy barrier position of r=2.29±0.04 Å characterizing the dissociation of concanavalin A- carboxypeptidase Y molecular complex. The presented results show that both atomic force microscopy and quartz crystal microbalance can be used to determine quantitative parameters characterizing the specific molecular interaction. Both methods can be easily combined for complementary and/or alternative studies of a chosen molecular interaction. By preparing the samples in the same manner the direct comparison between the data obtained via atomic force microscopy and quartz crystal microbalance can be made.

Opis:
Many proteins in alive organisms have a domain structure providing them the possibility to reversible unfolding, which seems to play an essential role in those processes occurring in tissues which are controlled by mechanical cellular tension. In this work the atomic force microscopy was applied to investigate the mechanical properties of the single molecules of fibronectin, a protein participating in the important mechanical processes in extracellular matrix. The results showed that the conditions of mechanical stretching influence not only the force required to unfolding of a domain but also the increase in protein contour length induced by such unfolding event. Two mean values of the increase in length (called shortly the unfolding length) $L_1$ and $L_2$, were obtained and ascribed to unfolding of either the whole fibronectin domain of type III $(L_2)$ or its fragment $(L_1)$. Both unfolding lengths revealed similar dependence on the stretching conditions. This experimental observation of increase in unfolding length with increasing loading rate was successfully described with a combination of two theoretical models (Bell model and the worm-like-chain model), previously used separately in the analysis of protein unfolding. The general mechanical property of fibronectin domains was emphasized and proposed as a potential determinant of the cellular adhesion.

Opis:
It is shown in the present paper that gradually devitrified Co-based non-magnetostrictive metallic glass is an excellent model material to verify Louis Néel's theory of the Rayleigh rule. In the course of the calculations, Néel showed that the parameter p=bH$\text{}_{c}$a (where H$\text{}_{c}$ is the coercivity, a and b are the coefficients of a quadratic polynomial expressing the Rayleigh rule) is expected to range between 0.6 (hard magnets) and 1.6 (soft). However, the experimental values of this parameter, reported in the literature for a number of mono- and poly-crystalline magnets, are much greater than those expected from the theory presented by Néel (in some cases even by two orders of magnitude). The measurements, performed for a series of Co-based metallic glass samples annealed at gradually increasing temperature to produce nanocrystalline structures with differentiated density and size of the crystallites, have shown that the calculated values of the parameter p fall within the range expected from Néel theory.

Opis:
The present pot experiment studied the effect of different soil moisture contents (60 – 70% CWC (capillary water capacity) – control; 30 – 35% CWC – water stress) on buckwheat productivity, the gas exchange parameters and health of buckwheat nuts. It was found that water deficit affected adversely certain biometric features investigated (plant height, number of nuts per cluster) and caused a decrease in seed weight per plant. It was also shown that water stress reduced the values of the investigated gas exchange parameters (photosynthesis rate, transpiration rate, intercellular-space CO2 concentration, and stomatal conductance) relative to the control treatment. Different soil moisture contents did not have a clear effect on fungal colonization of seeds. The multiplex PCR assays did not enable the detection of the genes responsible for mycotoxin synthesis. Under water deficit conditions, an increase was found in the content of albumin and globulin fractions as well as of glutelin fractions.

Depth distribution of implanted species and microstructure of oxygen-containing Czochralski grown silicon (Cz-Si) implanted with light ions (such as $H^{+}$) are strongly influenced by hydrostatic pressure applied during the post-implantation treatment. Composition and structure of Si:H prepared by implantation of Cz-Si with $H_{2}^{+}$; fluence D = 1.7 × $10^{17} cm^{-2}$, energy E = 50 keV (projected range of $H_{2}^{+}$, $R_{p}(H)$ = 275 nm), processed at up to 923 K under Ar pressure up to 1.2 GPa for up to 10 h, were investigated by elastic recoil detection Rutherford backscattering methods and the depths distributions of implanted hydrogen and also carbon, oxygen and silicon in the near surface were determined for all samples. The defect structure of Si:H was also investigated by synchrotron diffraction topography at HASYLAB (Germany). High sensitivity to strain associated with small inclusions and dislocation loops was provided by monochromatic (λ = 0.1115 nm) beam topography. High resolution X-ray diffraction was also used.

Opis:
The magnetocaloric effect may be assessed indirectly by expressing it as the change in magnetic entropy in varying magnetic field, H, as the function of temperature, T. Magnetization, M=f(T,H), may be experimentally acquired from a series of isothermal measurements with variable field, or from a series of constant field measurements with variable temperature. The accuracy of magnetic entropy calculation depends on the number of series in these experiments. The aim of this work is to determine how little data is sufficient to obtain accurate results of magnetic entropy change calculations, on the basis of real, magnetocaloric materials. Pure gadolinium and a Ni-Mn-Cu-Ga Heusler alloy were studied. For both materials, the magnetic entropy change and relative cooling power were calculated from both experiments, with the decreasing number of experimental data. For both materials, the constant field experiment with only 6 field values provided only a 5% error of calculations, as compared to the experiment with 100 field values. The Arrott plots were also drawn for constant field mode with 6 field values, easily indicating the order of transition. Comparison of the calculation results suggests that the constant field mode magnetization measurement may be more accurate and faster than isothermal mode.

Opis:
We have studied the influence of ion implantation and post-implantation annealing regimes on the structural and optical properties of silicon matrix with ion-beam synthesized InAs nanocrystals. (100) Si wafers were implanted at 25 and 500°C, subsequently with high fluences of As and In ions. After implantation the samples were processed by furnace and rapid thermal annealing at 900, 950 and 1050°C. A part of the samples implanted at 25°C was additionally exposed to $H_2^{+}$ ions (100 keV, 1.2 × $10^{16} cm^{-2}$ in terms of atomic hydrogen). This procedure was performed to obtain an internal getter. In order to characterize the implanted samples transmission electron microscopy and low-temperature photoluminescence techniques were employed. It was demonstrated that by introducing getter, varying the ion implantation temperature, ion fluences and post-implantation annealing duration, and temperature it is possible to form InAs nanocrystals in the range of sizes of 2-80 nm and create various concentration and distribution of different types of secondary defects. The last ones cause in turn the appearance in photoluminescence spectra dislocation-related D1, D2 and D4 lines at 0.807, 0.870 and 0.997 eV, respectively.
