Luria’s interpretation of brain organization for language and aphasia is analyzed. He published two major books and a myriad of papers devoted to this topic. Luria is one of the major founders of contemporary aphasiology, as from the fundamental point of view as from the clinical perspective. His significant influence has continued during the 21st century. Many of Luria’s ideas have been integrated into contemporary aphasiology. His aphasia classification, however, remains partially controversial.

Present Understanding

1. Introduction. Studies of radiation damage in ceramics are of interest not only from a fundamental point of view but also because it is important to understand the behavior of ceramics in various practical radiation enyironments- fission and fusion reactors, nuclear waste storage media, ion-implantation devices, outer space, etc. A great deal of work has been done on the spectroscopy of point defects and small defect clusters in ceramics, but relatively little has been performed on defect agglomeration using transmission electron microscopy (TEM) in the same kind of detail that has been so successful in metals. This article will assess our present understanding of radiation damage in ceramics with illustrations using results obtained from the authors' work.

Ian Mcewan

Framed by cognitive-poetic and possible worlds theories, this article explores two 21st century novels by the British postmodernist author Ian McEwan. Building upon Ryan’s (1991) seminal conceptualisation of the theory in relation to literature and using the novels as case studies, possible worlds theory is used to explain the unique and destabilising stylistic effects at play in the texts, which result in a ‘duplicitous point of view’ and consequent disorientation for the reader. With reference to the stylistically deviant texts of McEwan, it is argued that revisions to current theoretical frameworks are warranted. Most significantly, the concepts of suppositious text-possible worlds and (total) frame readjustment are introduced. Further to this, neuropsychiatric research is applied to the novels, highlighting the potential for interdisciplinary overlap in the study of narrative focalisation. It is concluded that the duplicity integral to both novels’ themes and texture is effected through artful use of hypothetical focalisation and suppositious text-possible worlds.

Zinc and its alloys seem to be promising candidates for biodegradable applications. Those materials are often modified by other elements or compounds in order to enhance their properties. The combination of zinc and apatites is challenging for several reasons. However, the advantages connected with the biological aspects suggest the need for further research into such materials. In this study, three zinc-based composites with 4 and 8 wt. % of nanohydroxyapatite or nanomonetite (Zn-4MO, Zn-4HA, Zn-8HA) were prepared by sintering and subsequent extrusion. Materials prepared in this way were characterized from the microstructural, mechanical and corrosion point of view. The obtained results showed a significant influence of particle character (amount and morphology) on the strength and ductility of the prepared materials. In case of Zn-4MO, the presence of monetite significantly increased the ductility compared with the other materials. In addition, the increment of the degradation rate caused by the presence of monetite was observed as well. All obtained results pointed out to significant advantages of monetite for the preparation of Zn-apatite composites compared with hydroxyapatite.

Abstract. Trafficability in forest terrain is controlled by ground-bearing capacity, which is crucial from the timber harvesting point of view. In winter, soil frost affects the most the bearing capacity, especially on peatland soils which have in general low bearing capacity. Ground frost similarly affects the bearing capacity of forest truck roads. A 20 cm thick layer of frozen soil or 40 cm thick layer of snow on the ground may already be sufficient for heavy forest harvesters. In this work, we studied the impacts of climate change on soil frost conditions and, consequently, on ground-bearing capacity from the timber harvesting point of view. The number of days with good wintertime bearing capacity was modelled by using a soil temperature model with a snow accumulation model and wide set of downscaled climate model data until the end of the 21st century. The model was calibrated for different forest and soil types. The results show that by the mid-21st century, the conditions with good bearing capacity will decrease in wintertime in Finland, most likely by about 1 month. The decrease in soil frost and wintertime bearing capacity will be more pronounced during the latter half of the century, when drained peatlands may virtually lack soil frost in most of winters in southern and western Finland. The projected decrease in the bearing capacity, accompanied with increasing demand for wood harvesting from drained peatlands, induces a clear need for the development of sustainable and resource-efficient logging practices for drained peatlands. This is also needed to avoid unnecessary harvesting damages, like rut formation on soils and damage to tree roots and stems.

This paper addresses the development of efficient numerical solvers for EHL problems from a rather fundamental point of view. A work-accuracy exchange criterion is derived, that can be interpreted as setting a limit to the price paid in terms of computing time for a solution of a given accuracy. The criterion can serve as a guideline when reviewing or selecting a numerical solver and a discretization. Earlier developed multilevel solvers for the EHL line and circular contact problem are tested against this criterion. This test shows that, to satisfy the criterion a second-order accurate solver is needed for the point contact problem whereas the solver developed earlier used a first-order discretization. This situation arises more often in numerical analysis, i.e., a higher order discretization is desired when a lower order solver already exists. It is explained how in such a case the multigrid methodology provides an easy and straightforward way to obtain the desired higher order of approximation. This higher order is obtained at almost negligible extra work and without loss of stability. The approach was tested out by raising an existing first order multilevel solver for the EHL line contact problem to second order. Subsequently, it was used to obtain a second-order solver for the EHL circular contact problem. Results for both the line and circular contact problem are presented.

In this paper, we discuss the concept of a metamagnetic quantum critical end-point, consequence of the depression to zero temperature of a critical end-point terminating a line of first order first transitions. This new type of quantum critical point (QCP) is interesting both from a fundamental point of view: a study of a symmetry conserving QCP, and because it opens the possibility of the use of symmetry breaking tuning parameters, notably the magnetic field. In addition, we discuss the experimental evidence for the existence of such a QCP in the bilayer ruthenate Sr3Ru2O7.

<p>The spatiotemporally resolved monitoring of membrane translocation, <i>e.g.,</i> of drugs or toxins, has been a long-standing goal. Herein, we introduce the fluorescent artificial receptor-based membrane assay (FARMA), a facile, label-free method. With FARMA, the permeation of more than hundred organic compounds (drugs, toxins, pesticides, neurotransmitters, peptides, etc.) through vesicular phospholipid bilayer membranes has been monitored in real time (µs-h time scale) and with high sensitivity (nM-µM concentration), affording permeability coefficients across an exceptionally large range from 10<sup>–9</sup>‑10<sup>–3</sup> cm s<sup>–1</sup>. From a fundamental point of view, FARMA constitutes a powerful tool to assess structure-permeability relationships and to test biophysical models for membrane passage. From an applied perspective, FARMA can be extended to high-throughput screening by adaption of the microplate reader format, to spatial monitoring of membrane permeation by microscopy imaging, and to the compartmentalized monitoring of enzymatic activity.<b></b></p>

Summary The aim of the article was the intraindividual evaluation of reaction time at the Women’s World Athletics Championships from 1999 to 2019.We generated the rating of sprinters from the age point of view with comparison of two periods with different false start rules. In the result section, we analysed the sprinters that took part at World Championships (WCH) at least 3 times and appeared in the final. We assessed the reaction speed from the ageing point of view, or more precisely with the changing conditions when judging the false start. The results confirm that the stricter start judging rules in sprint disciplines did not have a significant influence on the reaction speed. We also confirmed a research that the sprinters older than 30 years can achieve very low reaction time at the start.

The Relationship

 According to some thinkers, in the 21st century, the Japanese society is facing a crisis of values. The postmodern approach to the individual and society may be one of the causes of this problem. In this point of view, an inadequate grasp of the relationship between the individual and the society seems to play an important role. The problem of this relationship was elaborated by the early 20th century philosopher Watsuji Tetsurō who endeavoured to re-define the role of an individual in the society. This paper attempts to examine the contemporary problem of Japanese identity from the perspective of Watsuji’s conception of interpersonal relationships.
