Trial schematics are ubiquitous within psychology journals articles and have the potential to inform how we think about time in space from a non-linguistic point of view. Graphical representations of trial schematics were used to compare the spatial representations of time used by the scientific community with the dominant spatial stereotypes for temporal events reported by the scientific community. From 294 observations, approximately 81% of trial schematics contained left-to-right and / or top-to-bottom representations of first-to-last events, consistent with the dominant Western spatial expressions of time. An initially counter-intuitive left-to-right but bottom-to-top spatial stereotype used in approximately 18% of schematics is discussed with respect to its potential perceptual origins. The complications that arise from the use of multiple spatial axes in the representation of time are highlighted and given the tendency for trial schematics to be informationally poor, alternative routes for the supply of thorough experimental detail are suggested.

In this research work, the antioxidant and metabolomic profiling of seven selected medicinally important herbs including Rauvolfia serpentina, Terminalia arjuna, Coriandrum sativum, Elettaria cardamom, Piper nigrum, Allium sativum, and Crataegus oxyacantha was performed. The in vivo cardioprotective potential of these medicinal plants was evaluated against surgically induced oxidative stress through left anterior descending coronary artery ligation (LADCA) in dogs. The antioxidant profiling of these plants was done through DPPH and DNA protection assay. The C. oxyacantha and T. arjuna showed maximum antioxidant potential, while the E. cardamom showed poor antioxidative strength even at its high concentration. Different concentrations of extracts of the said plants exhibited the protection of plasmid DNA against H2O2 damage as compared to the plasmid DNA merely treated with H2O2. The metabolomic profiling through LC-MS analysis of these antioxidants revealed the presence of active secondary metabolites responsible for their antioxidant potential. During in vivo analysis, blood samples of all treatment groups were drawn at different time intervals to analyze the cardiac and hemodynamic parameters. The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs.

Deemed as poorly represented in nature, aurones have been often overlooked by researchers compared to other members of the flavonoid superfamily. However, over the past two decades, they have been reassessed by the scientific community, who are increasingly appreciating their ability to modulate several biological pathways. This review summarizes the recent literature on this class of compounds, which has been analyzed from both a chemical and a functional point of view. Original articles, reviews and editorials featured in Pubmed and Scifinder over the last twenty years have been taken into account to provide the readers with a view of the chemical strategies to obtain them, their functional properties, and their potential of technological use. The resulting comprehensive picture aims at raising the awareness of these natural derivatives as effective drug candidates, fostering the development of novel synthetic analogues.

The translation of religious texts has always been a perilous undertaking, especially when it concerns a sacred text. Indeed, seeing translation as an act of communication requires a knowledge of the communicative parameters that constitute it. The translator-speaker, who plays the role of intermediary, must create an interaction at the level of meaning and its semantic components. From this emerges the role of the addressee as the main protagonist and the only interpretative force of the message. Thus, the process of negotiation manages the translating activity, since the transfer of a message is not only reduced to a process of reformulation of the source text in another language, but, largely exceeds this compartmentalization. We will first discuss the challenges and stakes of the translation of religious texts, which we have chosen to illustrate with examples that make this aspect clear. Then, we will insist on the question of the translation as a semantic negotiation, considering that there is a confrontation between transmitter and receiver from the point of view of knowledge, historical and linguistic references. Indeed, this facet of the pyramid where the cultural dimension of translation and interpretation is played out remains unknown and implicit. It is quite easy to reveal what is related to the cultural, social and historical reality of a particular receiver. But that is not enough to communicate, it is also necessary to question the cultural references of this one, the representations conveyed by the language. Indeed, we have chosen to present examples of the Holy Qur'an translated by translators of different religions, and given that some translations have deviated from the noble mission of translation, in this case, the faithful transmission of the meaning, without any objectivity whatsoever, especially when it is a sacred text whose inimitability is not to be proven or tested. Thus, the difficulty in our choice stems, on the one hand, from the sacred character of the chosen writing, and on the other hand, from the nature of research in this field which is condemned to remain always relative. Since several elements control the translation of the sacred text, namely, the language, the tradition and the personal factors of the translator. Finally, the field of religious translation requires a great deal of precision and neutrality, and a constant rethinking of the fact that the slightest subjective or cultural interpretation could call into question our research work. Thus, when it comes to cultural transfer, the translator's task is to take into consideration the knowledge that already exists in the target culture about the source culture. Indeed, it is necessary to know how to relate the knowledge concerning the target culture to the knowledge via the source culture. The translator is the first receiver who receives and interprets the message; he will therefore try to understand the source culture with his own knowledge and value judgments. The translator is indeed a mediator because he assumes two roles, that of receiver and reader of the source message, however, the translator having a task of reader which must be different from that of the normal reader, since he must undoubtedly appropriate the competence of mediator in communication which crosses with the function of transmitter of the translated message. Moreover, this same message undergoes a second transfer; the target reader receives it and interprets it in turn according to his own ideological and cultural schemes. Thus, the process of the translated text is not limited to a single phase, but, it enchains back and forth during which the text acquires the imprint of the translator who makes the transfer. Without forgetting to negotiate the meaning by respecting all the circumstances of the original text. So, to what extent can this semantic negotiation communicate the said and the unsaid of the text? .

The castle Colonna of Arnara: from the restoration of the monument to the enhancement of the ancient village and its territoryThe castle of Arnara, is located in Ciociaria in southern Lazio, in what was once the feud of the Conti of Ceccano. For the territory it is the most important monumental complex of medieval architecture. In fact, despite its small size, it is one of the few examples of fortified architecture still original in its essential lines. This castle represents an exceptional case of sedimentation and stratification, which even today, from its reading, allows us to reconstruct both its historical events and those related to the urban development of the adjacent historic village. Moreover it can be considered of priority importance also from the urbanistic point of view because it represents the first historical nucleus of Arnara. Unfortunately, today, the castle is in a bad state of conservation. With the passing of time its conditions have become more and more aggravated also because of the complex events linked to the various passages of property, of private and public nature, which have strongly influenced the management of the monument. The study of the castle of Arnara is part of the national and international debate that considers participation a key factor for the sustainable enhancement of the cultural heritage, because it promotes greater awareness of its social and economic value. The objective of the research work is to develop, taking the castle as a case study, a new approach that sees cultural heritage (tangible and intangible) as an irreplaceable heritage of knowledge and as a precious resource for economic growth, employment and social cohesion; therefore a cultural heritage seen as a driving force. In the specific case of Colonna Castle, attention has been focused on the importance of being able to activate virtuous circles around this very important place of culture, enhancing its role as a centre of knowledge and incubator of creativity and social innovation.

In our research work we aimed at carrying out an economical assessment of an investment and development of substantial volume. The examined project was completed at a pig-farm during which a new farrowing place and pig rearing building were built, as well as the renovation of the existing pig-farm. All of them were financed partly from the firm’s own source, partly from a non-repayable aid granted by the state, and finally from a credit granted by a commercial bank. The term of the credit is 10 years and the return of the investment expected by the investors is 8%, so we carried out our calculations according to these data. We examined the three possible ways of financing the investment from the economical point of view, as a result we proposed three hypotheses. Our hypotheses are: Hypothesis 1 (Case „A”): The investment will be financially recovered within the examined period of 10 years if it is financed from the firm’s own source, the state grant and the bank credit. Hypothesis 2 (Case „B”): The investment can be economically completed within the given period of time if the project meets the costs from the firm’s own source and the credit. Hypothesis 3 (Case „C”): The investment will be economically accomplished within the examined 10 years provided the firm finances the project from their own source and the state grant. In our calculations we used the net present value (NPV), the internal rate of return (IRR), the payback time (PB), the discounted payback time (DPB) and the profitability index (PI) as economy indicators. We carried out our calculations regarding 10 years to be able to compare the results since the term of the granted credit is 10 years, too.

Many of the studies about mineral deposits are bringing great information to the scientific community, providing, for example, general characteristics of these deposits, possible source areas and its used in some cases as prospective tools to help in geological mapping. In this way, this study aimed to characterize the alluvial secondary deposits of columbite-tantalite that were found near vicinal 12, about 50km north/northeast of Rorainópolis city, between the BR-174 and BR-210 roads, in the state of Roraima (Brazil), bases on 4 samples that were brought by a resident of the region. To fulfill these objectives, some chemical and mineralogical methods were performed, like: magnetic separation, X-ray diffraction, X-ray fluorescence and petrographic description. The deposits of the region end up being characterized by having a large amount of Fe and Ti (mostly), containing in some places also a large concentration of Niobium and Tantalum. Not all samples have columbite-tantalite, showing that their concentration in some areas of the deposit is quite low. There are samples with less than 1% Nb and Ta and also samples with more than 20% Nb and 6% Ta concentration. These minerals were poorly transported, being identified by the degree of roundness and granulometry of the samples. A weathering cap on some minerals could also be verified. This research work turned out to be relevant, as it provides new data that add to the knowledge of the mineral potential, which has not been fully explored yet.

В статье излагается содержание двух базовых концепций неклассической философии и методологии науки: конвенционалистской и консенсуалистской теории природы научного знания и научной истины. Каждая из них является альтернативой двум основным парадигмам классической философии и методологии науки: эмпиризму (позитивизму) и рационализму. С точки зрения конвенционализма научное знание не есть ни описание чистого опыта, ни его обобщение. Но оно не является также и результатом некой априорной интуиции и чистого разума. Согласно конвенционализму научное знание - это система доказательной информации, исходные принципы которой имеют характер условных, конвенциональных истин. Отсюда следует, что любая истина в науке не категорична, а условна и имеет форму «если, то». Консенсуалистская концепция природы научного знания возникла в философии науки второй половины XX в. Она была, с одной стороны, обобщением конвенционализма, а с другой - его отрицанием. Если в конвенционализме основным субъектом научного познания является отдельный ученый, то в консенсуалистской эпистемологии таким субъектом является социальный субъект - научное сообщество. Научное познание имеет принципиально коллективный характер как в плане его получения в силу разделения научного труда, так и в плане его легитимации и оценки. Последние операции всегда являются результатом консенсуса научного сообщества. The article examines the content of two basic conceptions of non-classical philosophy and methodology of science: the conventionalist and consensual theory of the nature of scientific knowledge. Each of them is an alternative to the two main paradigms of classical philosophy and the methodology of science: empiricism (positivism) and rationalism. From the point of view of conventionalism, scientific knowledge is neither a description of pure experience nor a generalization of it. But it is also not the result of some a priori intuition and pure reason. According to conventionalism, scientific knowledge is a system of evidence-based information, the initial principles of which have the character of conditional, conventional truths. It follows that any truth in science is not categorical, but conditional and has the form «if, then». The consensual concept of the nature of scientific knowledge emerged in the philosophy of science of the second half of the twentieth century. It was, on the one hand, a generalization of conventionalism; on the other, a negation of it. If in conventionalism the main subject of scientific knowledge is an individual scientist, then in consensual epistemology such a subject is a social subject - the scientific community. Scientific knowledge has a fundamentally collective character, both in terms of its acquisition by virtue of the division of scientific work, and in terms of its legitimization and evaluation. The latest operations are always the result of a consensus of the scientific community.

The present paper documents and discusses research work associated with a newly designed passenger door structure demonstrator. The composite structure was manufactured from carbon-fiber-reinforced thermoplastic resin. A composite frame with a variable cross-section was designed, optimized, and fabricated using thermoforming technology. Both numerical simulations and experiments supported structural verification according to the damage tolerance philosophy; i.e., impact damage is presented. The Tsai-Wu and maximal stress criteria were used for damage analysis of the composite parts. Topological optimization of the metal hinges from the point of view of weight reduction was used. All expected parameters and proposed requirements of the mechanical properties were proved and completed. The door panel showed an expected numerically evaluated residual strength (ultimate structure load) as well as meeting airworthiness requirements. No impact damage propagation in the composite parts was observed during mechanical tests, even though visible impact damage was introduced into the structure. No significant difference between the numerical simulations and the experimentally measured total deformation was observed. Repeated deformation measurements during fatigue showed a nonlinear structure behavior. This can be attributed to the relaxation of thermoplastics.

The article is devoted to the analysis of the concert for piano and symphony orchestra by the modern Azerbaijani composer R. Agababayev. The article is very relevant from the point of view of identifying ways to implement classical traditions in a modern piano concerto of the 21st century. It must be said that in this issue we have found many such stylistic features that testify to the strong reliance of Azerbaijani composers on classical traditions. This article is devoted to the study of identifying the stylistic features of R. Agababayev’s piano concerto in the context of the historical development of this genre. Research methodology. The choice of the methodological basis for this study is due to the above goals and tasks that we set ourselves in the framework of this work. Based on the subject matter of the article, the methodological basis of this scientific work is a complex analysis, which implies the interaction of several research methods at different levels. The basis for the analytical analysis of the piano concerto was a theoretical approach, in which such aspects of the work as the problem of form formation, stylistic features of individual elements of the musical language are subject to research. The scientific novelty of the research lies in the fact that for the first time as special research work is the study and detailed analysis of R. Agababayev’s piano concerto. Conclusions. The main conclusion of our scientific research was to determine the stylistic features of the Azerbaijani piano concert created in the 21st century. Based on the data obtained during the analysis, we were able to determine the main trends and ways of development of this genre at the present stage of the development of Azerbaijani academic music. One of the important, if not decisive, aspect in achieving this kind of goal is to identify issues of preserving and transforming traditions, as well as innovative tendencies in the composer’s solution of a particular work. Single-movement piano concertos have become widespread in academic music since the beginning of the era of romanticism. And in the Azerbaijani one-part piano concerts, connections with romantic traditions are deeply felt. Moreover, in each specific work, these traditions are reflected especially. Since the concert by R. Agababayev demonstrates an interesting and original one-part interpretation, combined with an inner poly-part one, this is a typically romantic tendency associated with the composers’ desire to compress the cycle.
