A one-year field trial was established with the vine variety Ryzlink vlašský (Riesling italico) to evaluate the effect of spring soil applications and 5x repeated foliar application of magnesium fertilisers on yields and quality of grapes. On light soil of the experimental locality Žabčice (ca 25 km south of Brno) visual symptoms of Mg deficiency on vine leaves had been monitored in the past. The experiment involved 4 treatments: 1) unfertilised control; 2) spring soil application of Kieserite – 20 kg Mg.ha−1; 3) 5x foliar application of a 5% solution of Epso Combitop – Mg, S, Mn, Zn; 11.8 kg Mg.ha−1; 4) 5x foliar applications of a 5% solution of Epso Top – Mg, S; 14.8 kg Mg.ha−1.No significant differences among the treatments were detected in the contents of K (1.40–1.67%) and Ca (1.63–1.91%) in leaves sampled after the applications. After foliar applications the contents of Mg and S significantly increased in treatments 3–4 to 0.42–0.49% and 0.34–0.40 %, respectively compared to treatments 1–2 (0.29–0.30% and 0.22%, respectively). The content of Zn (173–380 mg.kg−1) and Mn (90–551 mg.kg−1) increased significantly in treatment 3 compared to the other treatments. The chlorophyll index did not differ among the treatments. Grape yields (t.ha−1) in treatments 1–4 were the following: 7.04–8.16–7.51–7.26 t.ha−1, respectively. Only the soil-applied treatment 2 differed significantly from the other treatments. The content of sugar (16.5–17.9 °NM), titratable acids (12.78–13.25 g.l−1) and the pH of must (3.02–3.11) did not differ among the treatments.

Abstract This paper is an attempt to investigate the current problems the students graduating in English at the ISLT1 are likely to encounter when setting out to render English into Arabic. My teaching experience with them was beneficial, albeit quite short (one year-long only, 2000-2001). The material gathered, on the other hand, was wide-ranging and, better still, so provocative that I readily agreed to venture onto dangerous ground.2 Studies in the past have often failed to delve deep into possible meanings and extend beyond traditional boundaries so as to assess the scope of words and explore the meaning potentials. Recent advances in the literature argue that translators should be sensitive to the losses and gains of cultural elements and assess the “weight” of these elements in the source text in order to bring about the same/similar effects. It is true that loss of meaning is inevitable and the transference to the translator’s language can only be approximate (Newmark 1988, 7). The current trend in translation theory is to explore situations to make it possible to transcend linguistic as well as cultural barriers. Translators will continue to reproduce only restricted facets of meaning so long as they do not vanquish ordinary processes of thought and approach the words in the SL text as units of discourse. I make no pretence at being able to offer definitive solutions. This account aims at identifying the potentially problematic areas in translating English into Arabic. The sense of new in this experience embodies a larger vision, apparently a different quality of recognition since the focal interest is laid on the interpretive weight of words as constituent parts of the act of communication.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

The quality of grapes is determined above all by the contents of the primary and secondary metabolites. The primary metabolites involve sugars and organic acids, and just these compounds are dealt with in this study. Its objective was to analyse and critically evaluate the primary metabolites in new interspecific varieties and, based on a comparison with European varieties of grapevine (Vitis vinifera L.), to find out the similarities and also possible differences between them. The study evaluates and compares 4 conventional varieties of Vitis vinifera with 11 new interspecific cultivars. The contents and compositions of the individual sugars and acids were estimated by means of the HPLC method. Most of these varieties belong to the group with either medium or low content of malic acid, i.e. with a medium to high β ratio. This corroborates the similarity of interspecific varieties to those of V. vinifera. The cluster analysis identified the existence of two interesting groups of varieties: the first one involved the varieties Riesling, Nativa, Marlen, and Kofranka while the other group consisted of varieties Blaufränkisch, Blauer Portugieser, and Laurot. This observation also indicates similarity between Vitis vinifera L. varieties and interspecific cultivars and demonstrates that the contents of the primary metabolites (i.e. sugars and organic acids) are also comparable.

This review discusses the main statistical indicators for lung cancer (LC) in the Moscow region over the past 20 years from 1998 to 2018. Methods. The analysis of basic statistics was carried out on the basis of official statistics of the Moscow region in the period from 1998 to 2018. Results. A decrease in the incidence was revealed. The five-year survival rate increased. The morphological diagnostics of LC improved. The detection of the disease in the early stages improved. In addition, mortality has decreased, both overall, and one-year. Conclusion. The reduction of morbidity and mortality, as well as the improvement of early detection of patients with LC in the Moscow Region was facilitated by the introduction of tobacco control measures, the implementation of programs to fight cancer, improving the quality of diagnostics and improving the equipment of clinics and hospitals, as well as the use of new modern treatment methods, such targeted and immunotherapy.

AbstractSouth Africa is indeed a country of many contrasts, of extreme wealth and extreme poverty. All South Africans were deeply affected by apartheid and this had a huge effect on how communities (including both offenders and victims) on all levels took shape: where they lived, the quality of their housing and neighbourhoods, the resources they had or did not have at their disposal, what schools their children attended, what opportunities they had for economic gain and how they were emotionally affected by the policies of apartheid. This article specifically intends to argue that communities should deal in a positive and urgent way with the divide caused by the past so that victims and offenders do not stay victims and offenders but are assisted to move on in their life journey towards healing and wholeness. The author believes that the key for reaching this goal is justice, especially restorative justice. With this qualification in mind the article wants to argue that the Christian church in particular can play a central role in implementing restorative justice in local communities. This will ultimately help to break the destructive cycle of being a victim today and an offender tomorrow, or the other way round.

During the past decade the view of Parkinson’s disease (PD) as a motor disorder has changed significantly and currently it is recognized as a multisystem process with diverse non-motor signs (NMS). In addition to been extremely common, these NMS play a major role in undermining functionality and quality of life. On the other hand, NMS are under recognized by physicians and neglected by patients. Here, we review the most common NMS in PD, including cognitive, psychiatric, sleep, metabolic, and sensory disturbances, discuss the current knowledge from biological, epidemiological, clinical, and prognostic standpoints, highlighting the need for early recognition and management.

Abstract Many philosophers have argued that psychological time is a fundamental, inherent quality of consciousness that provides continuity and sequence to mental events—enabling memory. And, since memory is consciousness, psychological time enables the individual intentionality of consciousness. Levinas (1961), on the other hand, argues that an individual’s past, in the most original sense, is the past of other. The irreducible alterity of one’s past sets the stage for the other who co-determines the meaning of the past. This paper is about the exploration cultural memory within the context of a Caucasian doctoral student entering into an African-American community during an internship, who finds that cultural memories are remarkably more complicated than the propositional description of historic events. The paper further explores how cultural memory is not a record of “what happened” but a sociolinguistic creative meaning making process. Histories can be contested. Memory, on the other hand, never adheres to the strict true or false dichotomy. Memory is like searching for the Divine, it cannot be found, only revealed in mysterious and small details. Memory, is the intruding of the infinite, creating as an effect the idea of a finite (August, 2011), they are not “representations” of the past nor are they a kind of mnemonic system of subjectivism to mediate all of consciousness.

The post-Stalinist interest shown by the Soviet Union in the non-aligned nations of Southern Asia has been accompanied by a corresponding increase in the quantity and quality of material dealing with this area appearing in leading Soviet scholarly journals. Though there has been the usual spate of propagandistic articles lauding the growing evidences of expanding cultural, economic, and political relations between the Soviet Union on the one hand, and India, Afghanistan, Burma, and Indonesia on the other, it would be a mistake to dismiss all such Soviet endeavors as unworthy of serious attention. Much of the material reflects a diligent effort by Soviet orientalists to analyze the past and the present of the nations of Southern Asia with a view toward making up for the previous period of flagrant neglect.
