Domeenit ovat valkuaisaineiden eli proteiinien itsenäisiä yksiköitä, joilla on tietty rakenne ja toiminta. Domeenit säätelevät soluissa monia proteiinien välisiä vuorovaikutuksia, jotka ovat tärkeitä solunsisäisessä viestinvälityksessä. Toiminnallisen viestivälityskoneistonsa avulla solu pystyy erilaistumaan, kasvamaa…

Abstract This paper is related to 16Mo3, a low-alloy steel typical in the manufacture of large welded steel casings of heavy-duty gas turbine engines. The usual practice in manufacturing is to stress relieve these housings after fabrication welding. If, however, weld imperfections are detected by non-destructive testi…
In this paper we study certain strong differential subordinations and superordinations obtained by using some new integral operators introduced in (Oros and Oros in Differential subordinations obtained with some new integral operator (to appear)). MSC: 30C80, 30C45, 30C20, 34A40.
n-Type nanocrystalline FeSi2/intrinsic Si/p-type Si heterojunctions were prepared by FTDCS. In order to estimate their diode parameters such as ideality factor, barrier height and series resistance, their current-voltage characteristics were measured in the temperature range from 300 to 77 K and analyzed on the basis…
A well adherent copper deposit on the Mg alloy (AZ31) can be obtained with a pretreatment with galvanostatic etching then followed by copper electrodeposition in an alkaline copper-sulfate plating bath. Experimental results show that the effect of galvanostatic etching on copper electrodeposition depends strongly on p…
Abstract The title compounds are hydrothermally synthesized from aqueous mixtures of NH4VO3 and CdCl2.
Box-Wrench is a tool widely used in industry and especially suitable for screwing the bolt and the nut in the place where the space is very narrow and dent. In this paper, a process of hot extrusion box-wrench was presented. The structure of hot extrusion die and its working process were discussed. The feasibility of…
Aluminium doped zinc oxide (AZO) thin films were prepared by magnetron-sputtering. The optical and structural properties of the films were investigated by optical transmission spectra and X-ray diffraction (XRD) measurements, respectively. The results indicate that the AZO films have hexagonal wurtzite structure with…
Hydroxyapatite (HA) has been widely utilized in the biomedical applications due to its chemical and structural features that are similar to the natural bones. The addition of organic components enhances the flexibility of the HA-based composites which result in increasing its molding ability into any desirable shapes.…
With shape memory function of new smart material, the magnetic control properties of magnetic shape memory alloy could be used to fabricate intelligent actuators for vibration control of structures. In order to study its magnetic properties, this text selected Ni53Mn25Ga22 as the material for the research and developm…
Different behaviors of catechol, 3-methylcatechol, 3-methoxycatechol, 3,4-dihydroxybenz-aldehyde and 3,4-dihydroxybenzoic acid were studied in the presence of 2,3-diaminonaphthalene in the phosphate buffer/acetonitrile solution at room temperature.
The precipitation characterization of SUS 310S weld metal was investigated by TG/DSC and metallography technique. SMAW was selected for this study and then cut with water jet avoiding thermal effect. Austenitic is the main microstructure of weld metal because of high Creqv./Nieqv. Precipitation launched higher both %m…
This paper describes how glass transition temperature (Tg) and capacitance (Cp) of a nanomodified composite polymer changes as compared to that of its base polymer. Because of its versatile applications, polycarbonate materials (grade PC1100 and PC1220 respectively), which are commercially available, were chosen as th…
Highly ordered TiO 2 nanotube arrays on Ti substrates were prepared by an electrochemical anodization process in a mixture of glycerol and water containing 0.5 wt% NH 4 F and then thermally annealed from 400°C to 600°C. The sample structures were characterized by scanning electron microscopy and X-ray diffraction meas…
Abstract The new compounds K8Cu2.77Sn43.23, Rb8Cu2.8Sn43.2, Cs8Cu2.69Sn43.31, K8Zn3.78Sn42.22, Rb8Zn3.52Sn42.48, and Cs8Zn3.44Sn42.56 are prepared in quantitative yield by arc melting of the elements with Sn acting as self‐flux, followed by heating at 600 °C for 15 h.
Distribution transformer constitutes a significant asset for any distribution power system. Short circuit currents or forces can cause mechanical faults in transformer winding. In order to discover the hidden trouble of the transformer, in this paper, on-line monitoring system based on FRA method is developed, and sig…
Shock-induced phase transition under intensive impact loading can strongly change the dynamic behavior of materials and wave propagation features. Dynamic constitutive modeling is one of the key problems in this area. We established a 3D dynamic incremental constitutive equation of phase transition with N transforming…
