Among nanotechnology-based thermal insulation materials thermodynamic performance of nano-ceramic coatings generates intensive discussions. Complete agreement has not been found yet about the mechanism of their insulating effect. In the Laboratory of Building Materials and Building Physics at Széchenyi István University (Győr, Hungary) heat transfer resistance experiments have been performed in order to describe thermodynamic processes inside nano-ceramic coatings. Previous studies finding after new measurements conducted in 2016-2017 also supported the former assumption that in case of nano-ceramic coatings convective heat transfer coefficient might be taken into account in a different way. Results also showed that thermal insulating effect of nano-ceramic coatings could be caused by a relatively high surface heat transfer resistance.

We studied the electrical transport properties of indium contacted graphene, few layer graphite (FLG) and bulk graphite samples under ambient conditions. Some of the contacted samples showed nonlinear transport characteristics. The initial electrical properties of the samples were changed reversibly by light illumination and irreversibly by argon ion irradiation. Ion irradiation modified the nonlinear I–V characteristics to quasi-linear ones in many cases. The resistance of a graphene sample showed positive temperature coefficient.

Packing density of aggregate influences greatly the properties of concrete. Maximization of packing density increases the flowing ability and segregation resistance of the fresh concrete and the compressive strength of the hardened concrete. The determination of maximum density is difficult experimentally; therefore several models have been developed for that purpose. However, these models do not take the size of the formwork into account. In this study, 20 different formwork shapes were examined with defined aggregate fractions. Results show that increasing the formwork size increases the packing density of aggregate, and the growth depends on the formwork size and compaction method.

Hagyományos kezelésre refrakter, fistulás Crohn-betegek kezelésében a chimer antitumornekrózis-faktor-alfa- (infliximab-) terápia igen hatékony, bár a betegek egy részében infliximabrezisztencia alakulhat ki. A szerzők egy infliximabrezisztens, 12 éves Crohn-beteg fiú esetét ismertetik, akinek luminális gyulladása mellett 3 aktív perianalis fistulája is volt. Teljesen humanizált antitumornekrózis-faktor-alfa- (adalimumab-) kezelést követően a 10. héten a fistulák bezáródtak, a korábbi magas aktivitási index normalizálódott. Validált életminőségi mutatók szintén szignifikánsan javultak. Az eset alapján infliximabrezisztens Crohn-beteg gyermeknél az adalimumabterápia sikerrel alkalmazható.

Abstract

Background and aims: This study investigated the role of self-regulation competencies in general and specifically in a food-related context for the control of body weight in a three-year weight loss program. Methods: The sample consisted of 30 male and female adolescents (age range: 11–18 years) who participated in a three-year therapy program for severe obesity (mean BMI at the beginning of the intervention was 33.6). Assessment of self-regulation competencies was conducted at three different stages (1st–3rd graduation/class year). Therefore, three independent groups of adolescents (N = 10) at these different stages were tested (initial-to final-stage of therapy). At the time of testing the BMI of these groups significantly differed from 38.8 to 28.7. Analyses of covariance were performed to determine whether the adolescents also differed in self-regulation skills like “resistance to temptation” and food-related Stroop interference along with ameliorating their energy-balance regulation. Results: In addition to the main effects of age and body mass index, adolescents further displayed significant improvements of executive functions with respect to resistance to temptation and inhibition. Conclusions: Interventions aimed at enhancing energy-balance regulation in adolescents may further benefit from efforts to facilitate executive functions such as self-regulation and food-related cognitive inhibition.
