A exploração de petróleo é uma das principais atividades industriais do País, devido à variedade dos subprodutos e empresas envolvidas no setor. Para que seja possível extrair das bacias sedimentares tal produto, é necessário investimento de grande porte e alta tecnologia. As plataformas e serviços de perfuração estão entre as principais atividades que representam custos significativos para a execução do serviço de exploração. Para viabilizar o investimento e comercialização do barril do petróleo, essas atividades devem ser aprimoradas de maneira a atrair investidores a explorar campos de petróleo de forma cada vez mais eficiente e produtiva, contribuindo, assim, com a geração de riqueza e desenvolvimento da sociedade. Dentro deste cenário, o objetivo deste artigo foi a aplicação de modelagem de dados em um conjunto de parâmetros operacionais para suporte à avaliação de eficiência do processo de perfuração de poços offshore. Por se tratar de um processo que envolve variáveis distintas de entrada e saída, torna-se pertinente analisar poços em áreas homogêneas e identificar os principais parâmetros que permitam contribuir para o melhor desempenho no ganho de taxa em metros perfurados. Neste sentido, no aspecto da abordagem metodológica, o cálculo da eficiência foi avaliado, tomando como base os parâmetros pré-estabelecidos pela engenharia de perfuração, adotando-se, para a modelagem, o modelo clássico, orientado à saída, utilizado pela análise de envoltória de dados. Os resultados obtidos, a partir das variáveis e do modelo aplicado, permitiram uma percepção preliminar da eficiência do sistema de perfuração.

Phase correlation functions: FFT vs. FHT
Authors: Schirripa Spagnolo Giuseppe , Cozzella Lorenzo , Leccese Fabio
Published: April 2019

The ability to process an image is a crucial skill in many measurement activities. In image processing or pattern recognition, Fast Fourier Transform (FFT) is widely used. In particular, the Phase Only Correlation (POC) method demonstrates high robustness and subpixel accuracy in pattern matching. However, there is a disadvantage in the required memory machine because of the calculation of 2D-FFT. In applications in which the use of memory is a critical element, Fast Hartley Transform (FHT) seems to be a good substitute. In this context, the use of Hartley’s transform can be of interest for apps implemented on portable systems e.g. smartphones. In this article, we present a comparison of the implementations of the phase correlation function using FFT and FHT. Particular attention is given to the analytical steps necessary to implement the POC by means of the Hartley transform.
Thermographic and electrical characterization of a photovoltaic panel under partial shading conditions: a case study
Authors: Bucci Giovanni , Ciancetta Fabrizio , Fiorucci Edoardo , Delle Femine Antonio
Published: April 2019

Shading is one of the most critical factors that produces a reduction in power in photovoltaic (PV) modules. The main causes of shading are related to cloud cover; local specificity; natural characteristics; building and other civil works; and the presence of the PV system itself. A reduction in overall radiation produces a consequent reduction in electric power. Another more problematic effect is associated with the partial shading of the PV modules. The shaded cell behaves as a load, dissipating energy and increasing its temperature. This effect can involve irreversible changes to the PV module, with a decrease in performance that can even cause the destruction of the shaded cell.

The main aim of this work is the development of a testing procedure for the performance evaluation of commercial PV modules in the presence of partial shading on one cell. Tests were carried out using thermographic and electric measurements and by varying the shading levels according to IEC standards. Shading up to total darkening is achieved by means of a number of filters that reduce the direct solar irradiance.

As a case study, a complete characterisation of a 180 Wp polycrystalline PV module was performed according to the proposed testing procedure, showing that high temperatures can be measured on the shaded PV module surface even if only 50 % of the surface of one cell of the PV module is darkened.

Amando Lázaro Ros, uno de los traductores principales de la compañía, realizó la traducción. La primera novela del canon holmesiano es A Study in Scarlet. La historia narra el asesinato de dos hombres a manos de Jefferson Hope, quien se venga así de la muerte de su futuro suegro y su prometida. Sin embargo, en esta traducción encontramos que el motivo del asesinato es el castigo en lugar de la venganza. La razón de este cambio se encuentra en la denegación de la publicación por parte del sistema de censura franquista.El objetivo de este artículo es doble.

Thomistic Logic in Renaissance Italy: Girolamo Savonarola, Paolo Barbò, Crisostomo Javelli
Authors: Gili Luca
Published: April 2019

This paper is devoted to the formation of a ‘Thomist logic’ in Renaissance Italy. After having expounded the principles that should inspire any logic ad mentem Divi Thomae, the article focuses on three textbooks of ‘Thomist logic’: Girolamo Savonarola’s Compendium Logicae, Paolo Barbò’s Expositio in Artem veterem, and Crisostomo Javelli’s Compendium Logicae. I show that these textbooks display common features, such as the presentation of logic according to the order of the books traditionally included in the Organon.Savonarola maintained that propositions can only be in the present tense and cannot generate insolubilia. Barbò’s contributions to philosophy of logic are conspicuous and include an original discussion of the subiectum of logic and of the doctrine expounded in the Categories. Under the possible influence of Renaissance humanism, Javelli’s textbook includes a history of logic and historical and philological analyses.
Die Rezeption der Waffensalbe und des sympathetischen Pulvers im Osmanischen Reich des 17. Jahrhunderts // The Reception of Weapon Salve and Powder of Sympathy in the Seventeenth-Century Ottoman Empire
Authors: BACHOUR Natalia
Published: April 2019

Im siebzehnten Jahrhundert erlebte das naturmagische Denken in der Medizin eine Blütezeit. In der medizinischen Praxis verbreiteten sich Rezepte, die durch Sympathie und Antipathie zwischen Makro- und Mikrokosmos begründet wurden, wie etwa die Waffensalbe und das Sympathetische Pulver. In der zweiten Hälfte des siebzehnten Jahrhunderts fand die Iatrochemie durch Übersetzungen aus dem Lateinischen ins Arabische den Weg in das Osmanische Reich, wie es bei der Basilica Chymicavon Oswaldus Crollius (gest.1609) der Fall war. Das Werk enthält eine Vorschrift für die Waffensalbe « Unguentum sympatheticum seu stellatum Paracelsi », die ins Arabische übersetzt wurde. Diese Studie analysiert Textstellen im Zusammenhang mit der Transmission der Waffensalbe und des Sympathetischen Pulvers im arabischen und osmanischen Schrifttum des siebzehnten und achtzehnten Jahrhunderts und rekonstruiert die Übertragungsmodalitäten magischer Konzepte, welche der Verwendung der Waffensalbe zugrunde lagen. Die Studie zeigt, dass die lateinischen Texte einem Transformationsprozess auf textueller Ebene, aber auch hinsichtlich der astrologisch-magischen Konzepte unterlagen. Außerdem zeigt der Beitrag, dass ein europäischer Arzt das Sympathetische Pulver im Istanbul des siebzehnten Jahrhunderts therapeutisch einsetzte.The seventeenth century saw the spread of natural magic in medicine. Several remedies based on concepts of sympathy and analogy between microcosm and macrocosm were introduced into therapy, such as weapon salve and powder of sympathy. In the second half of the seventeenth century, European iatrochemical knowledge was introduced into the Ottoman Empire through translations from Latin into Arabic, such as the translation of the Basilica Chymica by Oswaldus Crollius (d. 1609). The book contains a recipe for weapon salve with the title « Unguentum sympatheticum seu stellatum Paracelsi » that was translated into Arabic. This study addresses the transition of weapon salve and powder of sympathy to the Ottoman Empire by examining Arabic and Ottoman texts from the seventeenth and eighteenth centuries. It also addresses the modalities of translation and transfer of magical concepts underlying the usage of sympathetic remedies. This paper reveals that the Latin texts underwent a transformation process on a textual as well as on a conceptual level, especially regarding astrological and magical concepts. The study shows that a European physician was probably using powder of sympathy in Istanbul in the late seventeenth century.
Jacopo de’ Barbari’s 'View of Venice' (1500): Image Vehicles Past and Present
Authors: HUFFMAN Kristin Love
Published: April 2019

This essay focuses on an iconic and ground-breaking woodcut – Jacopo de’ Barbari (c. 1460/70–1516) and Anton Kolb’s View of Venice (1500) – and an interactive museum installation that I first developed for Duke University’s Nasher Museum of Art. The exhibition uses the View as a point of departure for the development of multi-media displays about Early Modern Venice and the transfer of knowledge. Adopting Aby Warburg’s illustrative terminology, the essay extends understandings of the woodcut, namely its function as an ‘image vehicle’ and its invention and realization as a product of cultural pathways. This concept, ‘pathways of culture’, also relates to the digital methods and visualized media used in the exhibition where their application advances a new methodology in art history, just as Aby Warburg did in the early twentieth century. And like Warburg who privileged visual imagery and traced its ideological transmission with his Mnemosyne Atlas (1924–1929), the curatorial team of the exhibition uses and systematizes original visualizations to drive the analyses of art, architectural and urban history in new and exciting ways.

Analytical study of optical coefficient transmission system "illuminator – slabosolenym environment – receiver»
Authors:   National Research Tomsk Polytechnic University, Panin Vladimir F.
Published: April 2019

For early diagnosis of fires, optical sensors built on the non-geometrical principle are widely used. When designing such sensors, it is necessary to take into account the peculiarities of light scattering in a smoky environment. The aim of the work was an analytical study of the optical transmission coefficient in the system "illuminator-low - smoke medium - receiver". The methods of theoretical system analysis were used in the work. Theoretical studies of the optical transmission coefficient of the "illuminator-low - smoke medium - receiver"system are carried out. It is established that it depends on the angle of rotation. A smoke meter of this type can be a reliable smoke detector only at such threshold levels that significantly exceed the possible fluctuations in the content of aerosol interference in controlled atmospheres, for example, dust. The theory considered by the authors provides a basis for finding the limits of the resolution of smoke sensors in atmospheres with different degrees of aerosol pollution. The theory is used by the authors to construct an optical scheme of a small-sized highly sensitive smoke meter.

Due to the total use of pendulum seismic devices, there is no necessary information about destructive seismic effects. Their use fails the official antiresonance strategy for seismic protection of buildings. Modern speed measuring equipment rather than traditional pendulum-type devices should be used for the official recording of destructive impulses. The results can cause positive changes in seismic protection of buildings and structures. The article describes the mechanism of mutual adaptation of shear waves and upper soil layers allowing the waves to move in these weakly compressed layers, unable to perceive the stretching and shear. The theory was proved experimentally. It was noted that pendulum seismic devices cannot display destructive seismic wave impulses.

Published: April 2019

The aim of the work is to introduce clusterization principles in the solution of problems of energy efficiency and ecological safety of the existent building fund. The material of the research is the process of modeling of energetically effective architecture-building clusters. In this sense it is topical and expedient to elaborate technologies and schemes, able to support making decisions as to the formation of energetically effective architecture-building clusters. The main attention is paid to the solution of infrastructure problems of energy saving of the architecture-building branch, connected with the absence of universal models, distinct algorithms of the formation of energy efficiency clusters and reliable instruments of their activity optimization. But realization of advantages of energy efficiency clusters is possible only at introducing effective mechanisms of the formation of a structure, able to provide a result, optimal by an energy efficiency criterion. The work offers a scheme of the formation process of such structure. The synthesis of models of energetically effective architecture-building clusters is based on principles of the systemic construction of geometric models and provides the imitative modeling of different development scenarios of synthesized clusters. At this stage of the research a function of making decisions as to the real cluster formation is left for experts. But an algorithm of the synthesis of models provides the formation of a knowledge base that will be in further a base of an “internal model” of the intellectual system of supporting decisions making, elaborated for modeling cluster structures. The scientific novelty of the work is in the elaboration of theoretical bases of the technology of coordinating the structure with object properties.

Published: April 2019

The main aim of the work is to elaborate algorithms and structure of data of the intellectual system of decisions making, able to provide functioning of the organizational-technical system of technical regulation in building under uncertainty conditions. The ability of intellectual systems to function under uncertainty conditions of different types is provided by using methods of indistinct mathematics and organization of a data structure, formed for revealing uncertainty automatically. The main attention in the article is paid to forming a data structure and algorithm for revealing uncertainty, caused by excessive information. The material of the research is information, contained in normative documents, according to which the technical regulation of the Ukrainian building branch is realized. It is especially urgent to reveal conflicts of parameters and rules, connected with reformation of the legislation in a part, related to the technical regulation of the branch. The automatic revelation of uncertainty that results in a discordance or conflict of parameters and rules, essentially facilitates elaboration of project documents and realization of expert evaluations at stages of building and exploitation of unique objects. But introduction of such intellectual systems allows to raise a speed and reliability of the work of other systems of the documents’ circulation under transformation conditions essentially. The scientific novelty of the work is in using models of indistinct mathematics at formalizing norms and rules of the technical regulation in building and elaborating methods of their processing by the intellectual system of making decisions. The results of the work are demonstrated on the example of determination of a technical regulation parameter at excessive information, manifested in the presence of more than one normative document with instructions for determination of one regulation parameter. The probation and adaptation of norms and rules are realized in the legislative regulation of the activity in the Ukrainian building branch under conditions of changes, directed on improving the city-planning activity according to world standards.

Published: April 2019

An increase in the volume of bulk cargo transportation through international transport corridors necessitates the commissioning of tank containers. Intermodalization of a tank container predetermines its load in various operating conditions depending on the type of vehicle on which it is carried: aviation, sea, air or rail. The analysis of the operating conditions of tank containers, as well as the regulatory documents governing their workload, led to the conclusion that the most dynamic loads acting on the supporting structures during transportation by rail. Namely, during the maneuvering collision of a wagon-platform, on which there are tank containers. In this case, it is stipulated that for a loaded tank container, the dynamic load is assumed to be 4g, and for an empty (for the purpose of checking the reinforcement) – 5g. It is important to note that when the tank container is underfilled with bulk cargo and taking into account movements of fittings relative to fittings, the maximum value of dynamic load can reach significantly larger values. Therefore, in order to ensure the strength of tank containers, an improvement of their structures has been proposed by introducing elastic-viscous bonds into the fittings.

To determine the dynamic loading of the tank container, taking into account the improvement measures, mathematical models have been compiled, taking into account the presence of elastic, viscous and elastic-viscous bonds between the fittings, stops and fittings. It is established that the elastic bond does not fully compensate for the dynamic loads acting on the tank container. The results of mathematical modeling of dynamic loading, taking into account the presence of viscous and elastic-viscous coupling in the fittings, made it possible to conclude that the maximum accelerations per tank container do not exceed the normalized values.

The determination of the dynamic loading of the tank container is also carried out by computer simulation using the finite element method. The calculation takes place in the software package CosmosWorks. The maximum values of accelerations are obtained, as well as their distribution fields relative to the supporting structure of the tank container.

The developed models are verified by the Fisher criterion. The research will contribute to the creation of tank containers with improved technical, operational, as well as environmental characteristics and an increase in the efficiency of the liquid cargo transportation process through international transport corridors.
NOTION, TENDENCIES, MILESTONES, PRINCIPLES OF CRIMINALISTICS
Authors: Csaba Fenyvesi
Published: April 2019

Criminalistics is, in essence, mainly a practical and – to a smaller extent – theoretical science of criminal investigation, in other words, it is a branch of criminal sciences that explores, creates, systemizes and applies – within normative legal frames – means and methods for the detection (prevention) and proving of crime. Apart from the supplementary role of the effective – indirect and direct – prevention of crime, its basic functions comprise detection, obtaining as much and as reliable evidence as possible, providing a basis for and ensuring the ultimate establishment of criminal responsibility by the court. In summary, criminalistics is the science of the effective and professional investigation of crime.
The study shows the criminalistics’ continental and common law notion, contacts with other criminal and non criminal disciplines and actual world tendencies and the most important six theoretical principles. The author writes about the historical milestones of the development of criminalistics as a fact science.
All of them would be useful for the specialist, explorer, data collector, the efficient law enforcer, who undertakes risks and dangers, faces continual challenges, the “great fighter” on the real and virtual battlefields that seem unremittingly infinite, where he/she has really only one weapon in his/her hands: criminalistics as an “international treasure”.

One of the main directions of improving the concept of treatment of diseases of the gastrointestinal tract and liver, which is accompanied by dysfunction of the hepatobiliary system and intestines, was the search and development of herbal remedies with hepatoprotective effect with a laxative effect and concomitant prebiotic activity. Aim of the research: to study the antimicrobial and prebiotic properties of the studied phytosubstance obtained from the fruits of Prunus domestica. Materials and methods. The study of the antimicrobial activity of the test sample of plum fruit extract with fibers was performed in vitro by the method of multiple serial dilutions. The reference strains of the following microorganisms were used as the microbiological model: S.aureus-ATCC-25923, E.сoli-ATCC-25922, P. aéruginosa-ATCC-27853, B. subtilis-ATCC-6633, C.albicans-ATCC-885653. The determination of the prebiotic properties of the studied sample was carried out by the method of cultivation of bacteria Bifidobacterium bifidum No. 1 and L. rhamnosus R0011 ND on nutrient media, which included the composition of plum fruit with fibers. Results. Studies on the antimicrobial activity of plum fruit extract with fibers showed that the studied phytosubstance does not reveal antagonistic properties both with respect to gram-positive and gram-negative bacteria, as well as in the case of Candida fungi. The results of studies on the study of the prebiotic properties of the studied extract confirmed the improvement of the main physiological parameters of the culture of bifidobacteria strain Bifidobacterium bifidum No. 1 and the strain lactobacillus L. rhamnosus R0011 ND when the fruit plums with fibers were added to the culture medium. Conclusions. The conducted studies allowed to establish the prebiotic properties of the studied extract of plum fruits with fibers, which proves the promise of its use in complex therapy schemes for gastrointestinal pathology.

Published: April 2019

It is known that among 40–70 % of patients pollinosis can run in conjunction with pollen-food allergy syndrome (PFS), while development of PFS is associated with the consumption of fresh fruits, vegetables, nuts and spices. Clinical course and severity of the disease depend on the sensitization profile, which can be represented by proteins-panallergens (PR-10, profilins, nsLTPs). However, there is little information about the sensitization profiles of patients with pollinosis caused by pollen of spring trees in Ukraine.

Aim. To study the profiles of sensitization of children with spring pollinosis.

Methods. We examined 61 children (aged 4-17 years) with spring seasonal allergic rhinitis/rhinoconjunctivitis (SAR). To establish the diagnosis, all children were given questionnaires, skin prick tests (SPTs) with commercial pollen extracts, and prick to prick tests with fresh fruits, vegetables and nuts. Component resolved diagnosis (CRD) were detected using an ImmunoCAP system. (Phadia, 100).

Results. It has been found that in 43 children (70.5 %) had polinosis in combination with PFS, the main clinical manifestation of which was an oral allergic syndrome in 43 children (100 %). Among the causal food allergens that caused the manifestations of PFS were more apples, peaches, carrots and hazelnuts (consumption of which led to 11.6 % of children before the development of anaphylaxis). All of the examined children (100 %) had a positive IgE response to rBet v 1 at significant concentrations. In 9.3 % of children, panallergens were found at once from several botanical groups. Such panallergens: rBet v 2, rBet v 4, rPhl p 7, rPhl p 12, rArt v 3 are generally not defined in the control group children.

Conclusions. Birch related PFS are common in Ukrainian pollen-allergic children with nuts and fruits predominantly implicated. Sensitization profile of children with Birch-pollen syndrome is complex and associated with sensitization to panalergens. Clinicians should be worried of PFS in patients with a high degree of sensitization to birch pollen and even young children if they have birch sensitization.

Published: April 2019

Aim: Based on the classical principles, to determine the optimal conditions for centrifugation, PRP harvesing (platelet-rich plasma). To conduct a quantitative assessment of the substrate obtained under different conditions of centrifugation.

Materials and methods. Based on the basic principles of obtaining platelet-rich plasma (PRP) by centrifuging in containers with an anticoagulant followed by phase separation to obtain the final substrate, the efficiency of the technique under the conditions of single and double centrifugation as well as under different conditions of acceleration and centrifugation was evaluated.

Blood for follow-up was collected from 20 healthy volunteers (11 men, 9 women) average 25.3±4.1 in syringes of LuerLock design with ACD-A anticoagulant solution, and centrifuged. Centrifugation was carried out under controlled conditions using a centrifuge with rotating bowls of the rotor. Centrifugation was performed at an acceleration of 100-400g in time intervals up to 20 minutes. Activation of the substrate was performed with calcium chloride solution.

Quantitative evaluation of platelets of whole blood and the final substrate of PRP was carried out with a semi-automatic analyzer.

Results. The obtained results demonstrate the maximum level of harvesting efficiency when performing double centrifugation in the 150g×15 min+250g×10 min mode. Subject to this centrifugation protocol, it is possible to obtain a substrate that complies with the standardized requirements for PRP.

The maximum level of an increase in the number of platelets in the substrate in comparison with whole blood is determined at the level of ×4.36 with concentration (volume reduction) x5 in comparison with the volume of whole blood.

Conclusions. This study demonstrated the advantage of double centrifuging modes over single modes.

According to the results of the study, it was possible to determine the conditions for an optimal double-centrifugation mode (acceleration and duration), which allows us to achieve the most efficient concentration of the substrate.

Aim: increasing the effectiveness of diagnosis and further orthodontic-surgical treatment of various clinical forms of hyperdontia (supernumerary teeth) and preventing recurrence with the use of cone-ray computer tomography data in orthodontic practice.

Materials and methods. The clinical case of patient (born in 2004) treatment is presented, with severe hyperdontia and retention of teeth that had little effect on the formation of the general configuration of occlusion. The patient's examination and treatment was carried out with the assistance of clinical, anthropometric and radiological data. The clinical method was to examine the patient and formulate a plan for further orthodontic therapy. The radiological method consisted of data analysis of cefalometry by Bjork, Steiner using a computer program and conducting a survey using a cone-ray computer tomography, followed by the use of these data in diagnosis and orthodontic treatment.

Results. Following the clinical and radiological methods of examination and subsequent orthodontic surgery, the corresponding end results were obtained:

1. The localization and topography of supernumerary teeth as the causes of relapse of pathology with the help of data obtained with the help of CBCT.

2. Radiographic picture reflected on the sagital and axial re-formats of tomograms for the diagnosis of supernumerary teeth, is more informative than diagnostics by standard diagnostic protocols.

3. After analysis of the study data, a more meaningful protocol of surgical intervention is prescribed.

4. Implementation of the results of modern diagnostics significantly influenced on the final result of orthodontic treatment.

Conclusions. Thus, in the process of corresponding work installed:

– the availability of computer tomography data is crucial for objective and qualitative diagnosis and treatment of hypertension.

– the general level of diagnostics during the intervention is significantly increased.
