The South American genus Praxelis Cass. (Asteraceae, Eupatorieae) includes 18 species and is the second-largest genus of subtribe Praxelinae. It is distributed from Colombia, Venezuela and the Guianas, to central Argentina, southern Brazil and north-western Uruguay. Over the past 40 years, one species, P. clematidea, has invaded several countries around the world. To understand Praxelis and its species, this study provides an updated taxonomy with the re-establishment of P. urticeafolim var. nanum as a synonym of P. ostenii, 16 lectotypifications, clarification of morphology and geographical distribution, brief descriptions, and the first key to all the species in the genus.
Relay interpreting
Authors: Pöchhacker Franz 
Published: July 2022

Abstract
The unique features of interpreting as a situated process and performance to enable communication in real time
make relay interpreting a particularly complex manifestation of indirect translation and a rich area of investigation. Even so,
the great potential of relay interpreting as an object of inquiry in Translation and Interpreting Studies has remained largely
untapped. This article seeks to map out the conceptual territory of relay interpreting as indirect translation with reference to
relevant factors and features. The analysis highlights the great diversity of scenarios that can be subsumed under the heading of
relay interpreting with reference to such key parameters as mode, modality, policy, linguality, multimodality, and technology.
The – regrettably modest – state of the art is reviewed with regard to types of research, topics, and methods; and some areas of
special interest, such as Deaf relay interpreting and speech-to-text interpreting relying on speech recognition technology, are
discussed for their potential to extend the scope of indirect translation to include intralingual and intermodal as well as
technology-based manifestations.
Translational phenomena in the news
Authors: Davier Lucile 
Published: July 2022

Abstract
Studies of news translation and indirect translation have challenged classical concepts of Translation Studies, but the two subfields have taken separate paths. This article applies Assis Rosa, Pięta, and Bueno Maia’s (2017b) classification of indirect translation to data collected via workplace studies conducted in two multilingual news agencies based in Switzerland and one monolingual broadcaster based in Canada. Illustrative examples are provided of the first six types of (in)direct translation in the classification. This typology allows for the inclusion of phenomena that may have been previously disregarded as translation, such as oral mediations and transfers from public-relations agencies to news agencies and other media outlets. However, news translation is a borderline case of translation that pushes Assis Rosa, Pięta, and Bueno Maia’s (2017b) classification to its limits because of the centrality of reported speech in news stories. Indirect translation seems to be able to bridge various subfields of Translation Studies.
Carrier density variation and linewidth enhancement factor in optically injection locked semiconductor lasers
Authors: Al-Hosiny Najm M 
Published: July 2022

Abstract
We theoretically investigate the behavior of carrier density variation in optically injected semiconductor lasers when varying the linewidth enhancement factor. The variation of carrier appears independent of the LEF in the positive detuning side, while decreased in the negative detuning side with any growth in the LEF. This variation is found to be enhanced when the injection level is boosted.

Both the conjecture in the static spherically symmetric case and the Penrose inequality for a dynamical spacetime with spherical symmetry are proved by imposing the null energy condition. We then generalize the conjecture to a general dynamical spacetime. Our results raise a new challenge for the famous unsettled question in general relativity: in what general case can the null energy condition replace other energy conditions to ensure the Penrose inequality?
A partial least squares regression model based on variational quantum algorithm
Authors: Hou Yan-Yan , Li Jian , Chen Xiu-Bo , Ye Chong-Qiang 
Published: July 2022

Abstract
Partial least squares regression (PLSR) is an essential multivariate correlation analysis method in machine learning field. In this paper, we propose a variational quantum algorithm for partial least regression (VQPLSR). By exploring the relationship between standard basis states and optimization, we design a cost function that can train regression parameters and weight vectors simultaneously. The VQPLS requires only one copy of variables as input, which reduces the complexity of quantum circuit implementation. Compared with PLSR, the VQPLSR achieves an exponential speed-up in the independent variable dimension n and dependent variable dimension w. Simulation results show that regression parameters and weight vectors can be constructed with the error ∼10−5 for 4 × 2 dimensional variable matrix. This algorithm inspires us to explore more quantum applications in machine learning.

Abstract
The toxicity of high-silica porous glasses in relation to Paramecium caudatum was investigated. The test results showed a generally acceptable toxicity range. The toxicity of porous glasses varies depending on the concentration and time of contact of the fine powder with water which may be is associated with the presence of sodium ions, fluoride and phosphate ions in an aqueous solutions.

Authors: Udvardi Bella , Géber Róbert , Kocserha István 
Published: July 2022

Abstract
The aim of the research is to produce geopolymer using secondary raw materials. In this research work concrete powder has been used as a raw material for the production of geopolymers, which belongs to the group of construction and demolition waste (CDW). Beside this various additives (silica fume, aerosil, calcium –stearate, metakaolin, and lime hydrate) have been used to improve mechanical strength. In the study the compressive strength of geopolymers of different compositions (7, 28 and 90 days) was tested, and the geopolymerization processes were identified by FT-IR apparatus. Based on the measurement results the combined mixture of metakaolin and aerosil succeeded in producing the highest compressive strength (=59,64 MPa) geopolymer paste.

Published: July 2022

Abstract
Powder hybrid materials based on 8-hydroxyquinolate lithium organic phosphor and - LaF3 inorganic fluoride matrix PbF2 have been synthesized. Hybrid materials were obtained by co-precipitation from aqueous-alcoholic solutions with ammonium fluoride under various conditions - different concentrations of precursor solutions, Pb/La ratio, and the siquensy of reagents’ mixing. All obtained hybrid materials showed effective broadband luminescence in the region of 390-500 nm. The photoluminescence intensity during reverse deposition was found to be higher than during direct deposition for different concentrations of reagents.
Model of transition zone evolution between coating and substrate under intense short thermal impulse
Authors: Knyazeva A G , Nazarenko N N 
Published: July 2022

Abstract
In the present work a model of the evolution of the composition of the transition zone between the material and the pre-applied coating under conditions of intense short-term thermal impulse is proposed. The pulse times are assumed to be comparable to the relaxation times of the heat and mass fluxes. This led to the need to account for finite rates of heat and mass propagation in the model, leading to hyperbolic transfer equations. The phenomena of thermodiffusion (Soret effect) and diffusive thermal conductivity (Dufour effect) and some possible chemical reactions leading to a change in the transition zone composition are also taken into account. This nonlinear model problem illustrates the necessity of the really coupled problem solution to reveal the feature of cross-effects in irreversible conditions. It was found that due to the wave heating and the wave nature of the movement of elements, chemical reactions can start during the action of a short pulse outside the heating zone expected only due to thermal conductivity.

Published: July 2022

Abstract
Plasma-polymer thin films were prepared under dusty plasma conditions. Due to their nanocomposite structure, the films showed unique mechanical properties including high elastic recovery resulting in a behaviour similar to superelasticity. The work is mainly focused on the characterization of the films by means of analytical scanning electron microscopy. We observed that variation of the deposition conditions caused substantial changes of surface topography of the deposited films. Consequently, the surface free energy varied in a wide range so it was possible to prepare films with either hydrophilic or hydrophobic properties.
The influence of different types of SCMs on microstructure and macroscopic properties of cementitious materials
Authors: Kopecskó Katalin , Mlinárik Lilla 
Published: July 2022

Abstract
In our study, the influence of different supplementary cementitious materials (SCMs) such as metakaolins, silica fume (microsilica) or filtered coal fly ash on the performance of concrete is discussed. The effects of different types and dosages of the SCMs have been investigated. Centrilit NC (MK1) and Metaver N (mk2) type metakaolins, Microsit® 20 (MS) type filtered coal fly ash or Centrilit Fume SX (SF) silica fume suspension was chosen as the replacement for the CEM I 42.5 N-SR0 sulphate resistant Portland cement. In addition to the two-component mixtures, we also examined the behaviour of the ternary blends, i.e. the combinations of SCMs. For the experiments, mortar prisms and cylindrical mortar specimens were prepared with water to binder ratio of 0.4. The paper presents the test results performed up to two years. The compressive strengths of the mixtures were examined. The most critical property of the cement-bound materials, the chloride migration coefficient of each mixture, was determined. The microstructure of the mixtures was determined by mercury intrusion porosimetry at the age of one year. Our results indicated (i) the best compressive strength was achieved for MK2 and for MK1 with combination of SF; (ii) the pore structure is much finer in the case of MK1 mixtures compared with those of MK2 or MS mixtures; (iii) the whole most frequent pore diameter interval falls into the range of medium capillaries only in case of MK1 (10 w%), for other mixtures the large capillaries are present in different extent. The SCMs greatly influence the extent of the enhancement in chloride migration coefficients with age: the less reduction was found for the mixtures of MK1, and the highest reduction was found for mixtures of MS. There is no direct function between the compressive strength, total porosity, specific surface of porosity or chloride migration coefficients.
Properties of red-mud-based geopolymers in the light of their chemical composition
Authors: Khalaf Ali Abdulhasan , Kopecskó Katalin 
Published: July 2022

AbstractUtilizing industrial waste materials such as red mud as alternatives to high emissions of CO2materials such as Portland cement will help to produce integrated sustainable construction materials. Statistical analysis has been performed on the major oxides of red mud to understand the relationship between chemical composition and properties (e.g., workability, setting time, compressive strength, etc.) of red mud-based geopolymer composite. Therefore, red mud can be a suitable binder by blending with other geopolymer source materials to achieve the desired fresh and mechanical properties. Moreover, a proposed equation has been derived on the basis of the outcomes from the literature to determine the required extra water that can compensate for the workability loss due to red mud addition.

Published: July 2022

Abstract
To assure safe traffic is a goal of the vehicle manufacturers. The car body elements are usually made from high plasticity metals whiches can deform in the case of an accident. By this deformation way, the car body absorbs the collision energy. Aluminium foam is a special material that can absorb impact energy. The authors wanted to find a rapid and simple test method to investigate the dynamic load effect for the aluminium foam. The Charpy impact test is a suitable and standardized impact test to determine the absorbed energy of the material during the fracture. In this research, the aluminium foam was tested by the Charpy impact test and compared the results with literature data to evaluate the used impact test.

Abstract
This article will present the ultrasonic welding technology of the stainless steel sheets, the joining with agreeing of the material science theory and metal-working rules-based executed experiments. Fusion welding is well understood and investigated in the case of steel. The ultrasonic welding in the case of metals causes different changes in the metals structure. The ultrasonic welding cause complex effect during the welding process. These effects are plastic deformation, heat, and ultrasound vibration. The goal of this research is to show the case of the experimented welded stainless steel (X5CrNi18-10) to determine the corrosion behaviour by non-destructive (visual test and microscopy) inspections. The stainless steel is sensible for all processes even that the cold working, heating and ultrasound effect. These effects can cause a decrease in the corrosion resistance of stainless steel.
Review article: Atmospheric Pressure, Water with Air, Porosity and Strength of Concrete (In memory of Professor László A Gömze)
Authors: Urakov Aleksandr L. 
Published: July 2022

Abstract
The review shows that the gas content in tablets and solutions of medicines can significantly change their physical and chemical properties, qualitative and quantitative characteristics of the mechanism of action of medicines when applied topically, and even allows you to turn “old” and known medicines into “new” medicines with completely new and previously unknown mechanisms of action. Therefore, artificial changes in the gas content in solid and liquid dosage forms were recommended as an original method of developing new drugs. It has been shown that this method is particularly promising for the development of new antiseptic, cosmetic and hygiene products. The fact is that the additional forced introduction of gas into a liquid or into solid through excessive pressure increases their volume, reduces their specific gravity and strength. Moreover, it allows you to “blow up” them by cold boiling. Conversely, the removal of gas from them due to vacuum reduces the volume, increases the specific gravity and strength. By analogy with the change in the physical and chemical properties of liquid and solid medicines, achieved by removing gases from them, it is proposed to reduce the porosity and volume of concrete and increase its specific weight and strength by degassing the water used for wetting cement in the concrete manufacturing process. Due to the fact that under normal conditions, the gas content in the water used for the manufacture of concrete directly depends on the atmospheric pressure, it is concluded that the production of concrete at different atmospheric pressure changes its quality. In particular, low atmospheric pressure can reduce the porosity and volume of concrete, as well as increase the specific gravity and strength of concrete. On the other hand, high air and/or gas pressure can increase the porosity and volume of concrete and reduce the concrete’s specific gravity and strength. Therefore, the amount of atmospheric pressure and/or air and/or gas pressure on concrete during its production should be included in the list of controlled indicators of concrete manufacturing technology.

Authors: Kareem Sarah , S.Al-Ansari Luay , Gömze László A. 
Published: July 2022

Abstract
To improve the mechanical properties of polymer, the mineral particles are added to produce composite material. For example, the mineral particles are added to polymer to improve the stiffness of polymer because of the higher stiffness of mineral particles. When the micron-sized particles are used in composite usually cause a reduction in impact resistance. On the other hand, adding the nano scale minerals leads to improve the impact and wear properties of the composite materials (nanocomposites). Several factors effect on the mechanical properties of nanocomposites like adhesion between the polymer and nanoparticles. If the interfacial deboning of particles from the matrix decreases, the tensile strength of the composite could be reduced.
In this article, the micromechanical models dealing with calculating modulus of elasticity of nanocomposite are reviewed and discussed using the comparison between the results of the micromechanical models with experimental data factors effect on the modulus of elasticity of nanocomposite are matrix and filler elastic modulus, volume fraction of filler, aspect ratio of filler, maximum volumetric packing and the thickness and elastic modulus of interphone surrounding the nanoparticles and these factors are studied in each mechanical models.
Effects of hydrogen peroxide on endothelial function in three-dimensional hydrogel vascular model and regulation mechanism of polar protein Par3

Published: July 2022

Abstract
Three-dimensional (3D) cell cultures better reflect the function of endothelial cells (ECs) than two-dimensional (2D) cultures. In recent years, studies have found that ECs cultured in a 3D luminal structure can mimic the biological characteristics and phenotypes of vascular ECs, thus making it more suitable for endothelial dysfunction research. In this study, we used a 3D model and 2D tissue culture polystyrene (TCP) to investigate the effects of cell polarity on hydrogen peroxide (H2O2)-induced endothelial dysfunction and its related mechanisms. We observed the cell morphology, oxidative stress, and barrier and endothelial function of human umbilical vein ECs (HUVECs) in 3D and 2D cultures. We then used Illumina to detect the differentially expressed genes (DEGs) in the 3D-cultured HUVEC with and without H2O2 stimulation, using clusterProfiler for Gene Ontology function enrichment analysis and Kyoto Encyclopaedia of Genes and Genomes pathway enrichment analysis of DEGs. Finally, we explored the role and mechanism of polar protein partitioning defective protein 3 (Par3) in the regulation of ECs. ECs were inoculated into the 3D hydrogel channel; after stimulation with H2O2, the morphology of HUVECs changed, the boundary was blurred, the expression of intercellular junction proteins decreased, and the barrier function of the EC layer was damaged. 3D culture increased the oxidative stress response of cells stimulated by H2O2 compared to 2D TCPs. The polarity-related protein Par3 and cell division control protein 42 were screened using bioinformatics analysis, and western blotting was used to verify the results. Par3 knockdown significantly suppressed claudin1 (CLDN1) and vascular endothelial cadherin. These results suggest that the polar protein Par3 can protect H2O2-induced vascular ECs from damage by regulating CLDN1 and VE-cadherin.
Rising temperature threatens China’s cropland

Published: July 2022

Abstract
The rising demand for calories and protein together with urbanization, pose significant challenges to China’s food security. The determination of policy actions requires accurate estimates of climatic impacts on both crop yields (intensive margin) and cropland area (extensive margin). However, the analysis of the latter has been limited, especially in developing countries. Here, we assess the impact of temperature on land use in China by matching high-resolution satellite data on land use with daily weather data from 1980 to 2010. We find that extremely hot weather (daily average temperature above 30 °C) has a long-lasting effect on reducing cropland in China. Combining climate projections from 39 downscaled climate models, we predict that climate change is likely to reduce China’s cropland area by 2.09%–25.51% under IPCC’s slowest and fastest-warming scenarios by the end of this century. In addition, we find that non-irrigated land is more susceptible to rising temperatures in the short term; however, irrigated land is subject to a similar impact in the long term. This result suggests that the adaptive effect of irrigation could be limited under persistent rising in temperature.
