Despite the progress in the understanding how COVID-19 infection may impact immunocompromised patients, the data on inborn errors of immunity (IEI) remain limited and ambiguous. Therefore, we examined the risk of severe infection course and hospital admission in a large cohort of patients with IEI. In this multicenter nationwide retrospective survey-based trial, the demographic, clinical, and laboratory data were collected by investigating physicians from 8 national referral centers for the diagnosis ...

Methylammonium lead bromide is a very perspective hybrid semiconductor material, suitable for high-sensitive, filter-free photodetection of electromagnetic radiation. Herein, we studied the effect of electrode spacing on the output performance and stability of planar-type photodetectors based on high-quality MAPbBr3 single crystals. Such crystals, as large as 4.5×4.5×1.2 mm3 were synthesized via the inverse temperature crystallization method and were further used for the fabrication of planar Au/ ...

• Energy generated by renewable sources must be stored during times of excess generation. • Vast arrays of means to store energy are available. • The most efficient energy storage is through hydroelectric and compressed air which is not available on small scale. • Arguably the best means of small scale energy storage is electrochemical. • Electrochemical storage using redox flow cells is one of the promising energy storage methods. As the deployment of solar and wind electrical energy increases, the intermittency ...

Thermal insulation materials based on natural fibres are some of the promising materials that are currently emerging on the construction market. These materials are important especially in terms of sustainable development, since they utilise renewable raw material resources or secondary materials and their production does not consume too much energy. However, a problem with these materials is the rather different behaviour during heat and moisture transport compared with conventional insulation, ...

The aim of this paper is to define direct operations and an operation of a power for relational structures and to prove their properties.In particular, a power satisfies the expected rules with the exception of (G")^ ^ G'^**.We derive sufficient con ditions for the vahdity of that law.1. Let / 7^ 0 be a set, let n-, be a positive integer for any i e I.A family (n^; i e /) will be called a type.The types {n^\ iel), {m^je j) are similar iff there exists a bijection cp: I ~-> J such that m^(i) = rii for all / e /.2.

An ordered set is a pair (G, <) where G is a set and < is an order on G, i.e. an irreflexive and transitive binary relation on G.We write briefly G instead of (G, <) if the order < is given.If < is an order on G, then the dual relation <* = > is an order on G.An element x e G is called the least element of (G, <) iïï x < y for any y e G ~ {x}; the greatest element is defined dually.If (G, <) is an ordered set and H Я G, then < n Я^ is an order on Я; this order is denoted by <|д or, briefly, also <, and the subset H = (Я, <) is called an ordered ...

The need for the development of new, advanced building materials increases every year, especially due to the necessary diminution of energy performance for building structures and for building production itself (including the production of building materials). Along with the energy performance problems in construction, the issue of CO2 emission associated with building and the production of building materials is also important. In the field of advanced thermal insulation materials, vacuum insulation ...

This study deals with the possibility of the utilization of composite materials with aggregate based on foamed glass bonded with cement. The idea of this study is to effectively use the advantages of the foam glass-based aggregate with a very low bulk density below 160 kg/m3 and a thermal conductivity of 0.069 W/(m.K). Foam glass-based aggregate is mainly made from waste glass that can no longer be recycled and used for the production of pure glass products. The purpose of the research is to produce ...

In [5] we have constructed, for any cardinal m, an m-universal cyclically ordered set.The m-universality is meant there in the following sense: For any cyclically ordered set G with cardinality ^ m there exists a subset G' of the universal set con structed such that G is a strong homomorphic image of G'.Here we present a con struction of a set with an asymmetric and cyclic ternary relation such that any cyclically ordered set of cardinality % m is isomorphic with its suitable subset.

Phase change materials (PCMs) are materials with the ability of absorption of latent heat based on a phase change. PCMs are able to store and release a large amount of energy at certain temperatures melting or freezing. The aim of the research is to verify whether this phenomenon (material) can be used within an external thermal insulation composite system (ETICS). This is particularly the usage of PCMs in the base coat. The research is focused on two main areas. The first area concerns the water condensation ...

Vacuum insulation panels (VIP) are thermal insulation materials with very low thermal conductivity. VIPs are commonly used in a broad spectrum of technical fields; however, they only see a small-scale application in civil engineering. The reason is mainly their high price and difficulty of installation. VIPs are very vulnerable to mechanical damage, which typically causes the loss of their thermal insulation properties. This paper deals with the possibility of effective incorporation of these insulation ...

The interface between two polarized liquids has applications in electroanalytical chemistry as a practical transducer arrangement. With same importance, such interface is studied with great interest by theoretical chemist and physicists to garner information about the fine structure of such interface. In our work we touch both of these aspects. In order to correlate the x-ray experimental work we determined Gibbs energies of transport for one supporting electrolyte and present a systematic method ...

In recent years, many researchers have addressed the issue of interior climate and how it affects human health. Investigations performed at schools and office buildings have found that CO 2 concentrations often exceed the limit value of 1500 ppm given in Decree No. 20/2012 Coll., on technical requirements for buildings. In addition, interior space often exhibits very low relative humidity. This results in poor conditions that are detrimental to human health and not conducive to studying and work. ...

This study is devoted to the possibility of using advanced insulation materials, such as Vacuum Insulation Panels (VIP), in the insulation and reconstruction of buildings, in connection with the green elements that are installed on the facade in the case of the use of external thermal insulation composite systems (ETICS). The use of VIP as part of the insulation system will result in a significant reduction in the required thickness of the insulation layer. In turn, the reduced overall thickness of ...
