A new method for accurate platelet thrombi volume measurement using a confocal microscope
Authors: De Zanet Denise , Battiston Monica , Lombardi Elisabetta , Specogna Ruben , Trevisan Francesco , De Marco Luigi , Affanni Antonio , Mazzucato Mario
Published: April 2019

The accuracy of quantitative measurements represents an essential pre-requisite to the characterization and definition of the complex dynamic phenomena occurring in the field of cell biology. In research projects that involve the induction of blood coagulation under flow in microfluidic artificial channels, thrombus volume is an important quantity for estimation as a significant index related to the individual thrombotic risk profile. Concerning its importance in the early diagnosis of cardiovascular diseases, the estimated thrombus volume should reflect and represent reality. In 3D confocal microscopy, systematic errors can arise from distortions of the axial distance, whose accurate calibration remains a challenge. As a result, the 3D reconstructions show a noticeable axial elongation, and the volume measurements are thus overestimated. In this paper, a 400-600 % volume overestimation is demonstrated, and a new easy to use and automatic calibration procedure is outlined for this specific microfluidic and optical context. The adaptive algorithm proposed leads to the automatic compensation of the elongation error and to the accurate thrombus volume measurement. The method has been calibrated using fluorescent beads of known volume, validated with groups of several distinct platelets and finally applied on platelet thrombi.
Setup for the dynamic calibration of bridge amplifiers from DC up to 10 kHz
Authors: Klaus Leonard , Beug M. Florian , Bruns Thomas
Published: April 2019

Measurements of mechanical quantities are often carried out with transducers with a bridge output. The output signals are conditioned using bridge amplifiers. If dynamically changing quantities are going to be measured traceably, the bridge amplifier must be calibrated dynamically.
This paper describes a dynamic bridge amplifier calibration setup based on the new PTB dynamic bridge standard. The calibration is carried out by the synchronous sampling of the bridge amplifier output voltage and a reference signal provided by the calibrated dynamic bridge standard. The dynamic bridge standard enables calibrations in a frequency range from DC (static calibration) up to 10 kHz. An overview of the different measurement uncertainty contributions is given, and the first measurement results show good agreement with a previously established measurement setup.
A new method for the calibration of strain cylinders using laser interferometry
Authors: Cui Junning , Kumme Rolf , Kahmann Holger
Published: April 2019

This research investigates the possibility of calibrating strain cylinders using laser interferometry, thus providing a new type of transducer that can provide both force and deformation indications. This new method for the calibration of strain cylinders is based on the application of a dual channel laser interferometer in a force standard machine. Using the proposed new method, the relationship between force, deformation, and strain can be calibrated in parallel when calibration forces are applied according to the procedure outlined in ISO 376. Experimental results show that the deformation of a strain cylinder has a definite and stable relationship with the force applied and can be calibrated and directly traced to the wavelength of the laser. Therefore, a new standard that can be used for both alignment verification and indication verification of compression testing machines and other uniaxial testing machines is proven. The research also illustrates the possibility of providing a new deformation-type force transducer using a non-gauged steel cylinder together with a multi-channel laser interferometer.

Notas para una traducción crítica de Lolita
Authors: Moreno Hernandez Carlos
Published: April 2019

El artículo trata de justificar la necesidad de una traducción crítica de Lolita, la novela de Nabokov cuya primera versión (1959), prohibida en Argentina, no llegó a España hasta 1975, donde se publicó expurgada hasta 1986, y luego siguió publicándose expurgada, con variantes, hasta 2002. Desde entonces, una nueva versión completa, parafraseada sobre la anterior, está en el mercado, sin que, al parecer, los derechos editoriales permitan recuperar la versión primera ni hacer otra distinta.La traducción crítica de Lolita que proponemos no sólo debe cotejar con el original las cuatro versiones al castellano indicadas, sino también con la primera traducción al francés de 1959, revisada por el autor, la segunda de 2001, la catalana de 1987, la italiana de 1993 -cotejada con la versión al ruso que hizo el autor en 1967-, y la traducción alemana en equipo de 1959 revisada y anotada en 1989 y 2017, esta última con indicaciones en nota de las variantes de la edición al ruso. Además, deberá incorporar el Postscriptum de la traducción al ruso y algunos de los comentarios en notas al texto original.
Estudio contrastivo del anisomorfismo cultural (Francia y España) de la terminología penal
Authors: Valdenebro Sánchez Jorge
Published: April 2019

Resumen: Los ordenamientos jurídicos, a pesar de que puedan pertenecer al mismo tronco común, como es el caso de Francia y España, son propios de cada país y, por ende, distintos al resto de ordenamientos de otros países. Esto da lugar en traducción a un anisomorfismo cultural. El traductor debe ser consciente de ello para no caer en errores de traducción que van a imposibilitar la comprensión del lector de la lengua meta. Conviene saber que, en traducción jurídica, no se traduce una realidad cultural por otra, sino que se tiene que manifestar en la lengua meta la realidad cultural de la lengua origen. Esto se presenta como un reto para el traductor, quien deberá contar con unos amplios conocimientos culturales de ambos países y una capacidad de documentación adecuada. Por eso, el presente estudio tiene como objetivo poner de relieve la importancia de los conocimientos culturales en traducción y, más concretamente, en traducción jurídica a través del análisis de una serie de términos que provienen de la rama jurídico-penal. En dicho análisis, encontraremos la explicación del concepto de la lengua origen, el contexto, la propuesta (o propuestas de traducción), la técnica de traducción que hemos empleado, así como comentarios en los que explicamos sus problemas de traducción y su anisomorfismo cultural.Palabras clave: anisomorfismo cultural, realidades culturales, técnicas de traducción, traducción jurídica, terminología penal. Abstract: The legal systems, even if they may belong to the same branche of law, as is the case in France and Spain, are specific in each country and, therefore, different from the rest of the legal systems of other countries. This results in translation to a cultural anisomorphism. The translator must be aware of this in order not to fall into translation errors that will make it impossible for the reader to understand the text in the target language. It is important to know that, in legal translation, one cultural reality is not translated by another, but that the cultural reality of the source language must be expressed in the target language. This is presented as a challenge for the translator, who must have extensive cultural knowledge of both countries and an adequate documentation capacity. Therefore, this study aims to highlight the importance of cultural knowledge in translation and, more specifically, in legal translation through the analysis of a series of terms that come from the legal-criminal branch. In this analysis, we will find the explanation of the concept of the source language, the context, the proposal (or translation proposals), the translation technique we have used, as well as comments in which we explain their translation problems and their cultural anisomorphism.Keywords: cultural anisomorphism, cultural realities, translation techniques, legal translation, criminal terminology.

The 'Pseudopythagorica' and their Philosophical Background. A discussion of Angela Ulacco, 'Pseudopythagorica Dorica'
Authors: CHIARADONNA Riccardo
Published: April 2019

This is a review article of Angela Ulacco’s recent Italian translation, with introduction and commentary, of four pseudo-Pythagorean treatises. Part 1 focuses on the philosophical background of the Pseudopythagorica and, more precisely, on the connection between these treatises and first century BC philosophy. Part 2 focuses on Pseudo-Archytas’s On opposites and discusses some parallels between this work and the early Peripatetic commentators (in particular Boethus of Sidon). Parts 3 and 4 focus on Pseudo-Archytas’s On principles. This treatise contains echoes of Aristotle’s theology and the same situation can be found in a famous fragment of Eudorus of Alexandria. It is argued that Plutarch’s references to Aristotle’s metaphysics and epoptics (see in particular Plutarch, Alex., 7) can shed some light on these issues.

Postoperative Analgesia for Pediatric Craniotomy Patients: A Randomized Controlled Trial
Authors: Xing Fei , An LiXin , Xue FuShan , Zhao ChunMei , Bai YaFan
Published: April 2019

Background: Pain is often observed in pediatric patients after craniotomy procedures, which could lead to some serious postoperative complications. However, the optimal formula for postoperative analgesia for pediatric neurosurgery has not been well established. This study aimed to explore the optimal options and formulas for postoperative analgesia in pediatric neurosurgery.

Methods: Three hundred and twenty patients aged 1 to 12-years old who underwent craniotomy were randomly assigned to receive 4 different regimens of patient-controlled analgesia. The formulas used were as follows: Control group included normal saline 100 ml, with a background infusion of 2 ml/h, bolus 0.5 ml; Fentanyl group was used with a background infusion of 0.1-0.2 μg/k·h, bolus 0.1-0.2 μg/kg; Morphine group was used with a background infusion of 10-20 μg/kg·h, bolus 10-20 μg/kg; while Tramadol group was used with a background infusion of 100-400 μg/kg·h, bolus 100-200 μg/kg. Postoperative pain scores and analgesia-related complication were recorded respectively. Comparative analysis was performed between the four groups.

Results: In comparison of all groups with each other, lower pain scores were shown at 1 hour and 8 hour after surgery in Morphine group versus Tramadol, Fentanyl and Control groups (P<0.05). Both Tramadol and Fentanyl groups showed lower pain scores in comparison to Control group (P<0.05). Nausea and vomiting were observed more in Tramadol group in comparison to all other groups during the 48 hours of PCIA usage after operation (P=0.020). Much more rescue medicines including ibuprofen and morphine were used in Control group (CI=0.000-0.019). Changes in consciousness and respiratory depression were not observed in study groups. Moderate-to-severe pain was observed in a total of 56 (17.5%) of the study population. Multiple regression analysis for identifying risk factors for moderate-to-severe pain revealed that, younger children (OR=1.161, 1.027-1.312, P=0.017), occipital craniotomy (OR=0.374, 0.155-0.905, P=0.029), and morphine treatment (OR=0.077, 0.021-0.281, P<0.001) are the relevant factors.

Conclusions: Compared with other analgesic projects, PCIA or NCIA analgesia with morphine appears to be the safest and most effective postoperative analgesia program for pediatric patients who underwent neurosurgical operations.

Effectiveness of Yi-Zhi-An-Shen Granules on cognition and sleep quality in older adults with amnestic mild cognitive impairment: protocol for a randomized, double-blind, placebo-controlled trial
Authors: Yue Shengnan , He Ting , Li Baiyang , Qu Yanqin , Peng Hongmei , Chen Jinxin , Lei Ming , Chen Chongli , Wu Wenbin
Published: April 2019

Background

Amnestic mild cognitive impairment (aMCI) is a syndrome characterized by significant forgetfulness that does not meet the criteria of dementia. Individuals with aMCI are at a bigger risk of progressing to dementia. Current studies suggest good sleep quality is linked with preserved cognition in the elderly, and sleep complaints are common among the elderly with amnesia. Therefore, improving their sleep may be helpful for maintaining and improving their cognitive capacity. According to the theory of traditional Chinese medicine, Yi-Zhi-An-Shen is an herbal compound which may ameliorate forgetfulness and sleep disorders. As growing evidence indicates that gut microbiome is associated with major mental symptoms, a hypothesis was proposed that Yi-Zhi-An-Shen Granules (YZASG) might work by alternating microbial abundance and diversity. In this study, the investigators intend to assess the efficacy of YZASG on global cognition in the elderly suffering from aMCI, and evaluate its safety as well as its potential mechanisms via sleep quality, fecal microbial 16SrDNA and metagenomics analyses, and serum markers.

Methods/design

This is a randomized, double-blind, placebo-controlled clinical trial. A total of 80 patients (aged 60~85 years) will be recruited and allocated randomly to a treatment group and a placebo group in a 1:1 ratio, then will be administered YZASG or isodose placebo three times a day. The intervention course is 16 weeks, with an 18-month follow-up. The primary outcome is Alzheimer Disease Assessment Scale-Cognitive subscale (ADAS-cog11). Secondary outcome measures are mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA), Pittsburgh Sleep Quality Index (PSQI), serum concentrations of immunological factors and inflammatory cytokines, fecal microbiota. Fecal microbiota will only be collected at the baseline and endpoint of the intervention.

Discussion

The results of this trial will be conducive to assessing the safety and effectiveness on cognition of YZASG in intervening aMCI among the elderly and determining if it takes effect via the improvement of sleep quality, regulation of gut microbita, concentration of certain serum markers.

Published: April 2019

Background: To provide and compare normal vascular parameters for cynomolgus macaques and healthy humans, compare the advantages and disadvantages of fundus fluorescence angiography (FFA) and optical coherence tomography angiography (OCT-A) in angiography, and establish an eye parameter database for cynomolgus macaques and healthy humans. Methods: 5 normal cynomolgus macaques with a mean age of 4.60±0.55 years were studied for data collection. A Heidelberg Spectralis® HRA+OCT was used to obtain parameters for FFA. The macula of 28 healthy humans (14 males and 14 females), with a mean age of 25.11±6.21 years and the optic discs of 9 healthy humans (4 males and 5 females) with a mean age of 28.56±6.78 years were measured. The vessel density (VD) was measured using an RTVue XR with AngioVue. The scan sizes of the macula and optic discs were 3×3 mm and 4.5×4.5 mm, respectively. Results: FFA of cynomolgus macaques revealed stages similar to those observed in humans. OCT-A was used to image the superficial and deep capillary plexuses and radial peripapillary capillary network. The highest entire en-face mean VD in the macular area was 68.19±0.75% in the choroid capillary layer. In both layers of the optic disc, the VD in the nasal quadrant was lower than the VD in the inferior temporal quadrant. Similarities and significant differences in VD between healthy humans and cynomolgus macaques were obtained using OCT-A. Conclusions: This study provides normal vascular parameters for cynomolgus macaques using FFA and OCT-A to help establish an optical parameter database for cynomolgus macaques and compare VD between healthy humans and cynomolgus macaques to promote choroid-retinopathy research.

The main task of the towed underwater vehicle (TUV) is the motion of technological equipment. Therefore, it is important to ensure the specified dynamic properties of the unit and automate the control of its motion. In the paper the typical forms of the unit are analyzed, the features of their control at small depths are set.

TUV control is carried out in conditions of uncertainty. Therefore, the design of an automatic control system (ACS) for its motion is proposed to be carried out using the appropriate synthesis method – the method of minimizing local functionals.

The control law contains integral components and, under the constraints of control actions, generates the problem of integral saturation. To eliminate the integral saturation in the work, the condition integration method is improved. On its basis, the control law and the structure of the controller of high dynamic accuracy of a second-order nonlinear object are synthesized. It is the basis for the synthesis of ACS controlled degrees of freedom of the underwater vehicle in conditions of uncertainty.

Usually TUVs contain two degrees of mobility. Translational motions of the unit are generated by changing its angular orientation. The paper synthesizes TUV controllers of pitch and roll based on the control law of the second order. Each control signal of the unit can affect both the roll and the pitch of the unit, which leads to decrease in the quality of control in general. To coordinate the work of controllers, a method is proposed, which is based on adjusting the initial conditions of the controller with greater error. On its basis, the automatic control system of the rotational motion of the unit is synthesized. It provides high dynamic precision control of two-dimensional rotational motion of the unit in uncertainty and is the basis for the ACS synthesis of its translational motion in space.

Self-propelled underwater systems belong to the effective means of marine robotics. The advantages of their use include the ability to perform underwater work in real time with high quality and without risk to the life of a human operator. At present, the design of such complexes is not formalized and is carried out separately for each of the components – a remotely operated vehicle, a tether-cable and cable winch, a cargo device and a control and energy device. As a result, the time spent on design increases and its quality decreases. The system approach to the design of remotely operated complexes ensures that the features of the interaction of the components of the complex are taken into account when performing its main operating modes. In this paper, the system interaction between the components of the complex is proposed to take into account in the form of decomposition of “underwater tasks (mission) – underwater technology of its implementation – underwater work on the selected technology – task for the executive mechanism of the complex” operations. With this approach, an information base is formed for the formation of a list of mechanisms of the complex, the technical appearance of its components is being formed, which is important for the early design stages. Operative, creative and engineering phases of the design of the complex are proposed. For each phase, a set of works has been formulated that cover all the components of the complex and use the author's existence equations for these components as a tool for system analysis of technical solutions.

The perspective of the scientific task of the creative phase to create accurate information models of the functioning of the components of the complex and models to support the adoption of design decisions based on a systematic approach is shown.

The obtained results form the theoretical basis for finding effective technical solutions in the early stages of designing remotely operated complexes and for automating the design with the assistance of modern applied computer research and design packages.
NOMADISM AS A WAY OF BEING OF THE IMMIGRANTS AND INTERNALLY DISPLACED PERSONS
Authors: Kolinko Marina
Published: April 2019

The article presents the innovatory understanding of the nomadic strategy of human being in the transitional condition. The aim of the article is to determine the role of the nomadic being way in the social group of internal migrants. It is substantiated, that aims and actions of a nomad are directed on creating new ways of realization and conceptualization of variants of nomadic being. It is explained, that a nomad doesn’t go by the way, offered by traditional types of activity, but searches innovatory ways of realization, doesn’t stop on deciphering of traditionally existing being senses, but produces them him/herself. A subject, living in a space of “boundaries” is deprived of the settled comfort, he/she searches for a possibility of balance and harmony, social recognition and improvement of own life conditions in the movement and change. The culture of choice, formed by the logic of the modern market, gives a nomad resources for regulating the own freedom degree. Nomadic instruments correspond to the migrants’ way of life. Digital nomadism creates stimuli for the active life and adaptation to new conditions of different groups of migrants.

Published: April 2019

At present, there are many housing estates being built in the world, whose urban and design assumptions must inscribe into a sustainable development trend and take into account the energy efficiency conditions of multi-family buildings in the overall economic and environmental perspective. At Seestadt Aspern, a new district of Vienna, one of the largest urban development projects in Europe, called Aspern Viennas Urban Lake, is being developed. A part of the Aspern Smart City Research (ASCR) research programme are projects involving innovative energy technologies and their achievements are tested under real-life conditions. The data is analysed by the ASCR and the aim is to optimise the energy consumption of the building, thereby reducing energy costs. The aim of this paper is to convey the energy concept of the newly emerging housing estates with sustainable construction characteristics as a signpost for the application of guidelines and standards in possible Polish solutions. Improved overall efficiency of future energy systems may prove to be significant if the use of renewable energy sources increases. The author’s research methodology was based on the analysis of literature data, the local vision of the housing estate, her own conclusions obtained within the framework of an information excursion with the participation of a guide from the ASCR research centre.

Authors: GROMYSZ Krzysztof , SŁOTA Damian
Published: April 2019

In this paper we present the application of the homotopy analysis method for determining the free vibrations of the simply supported beam. The linear and nonlinear cases are considered.

The homotopy analysis gives the possibility to search for the solution of a wide range of problems described by means of the operator equations. The numerical examples are presented to confirm the exactness and fast convergence of the introduced method. The presented computational examples confirm the precision and the fast convergence of investigated method. In the linear case we knew the exact solutions, so we could compare with them the solutions obtained with the aid of homotopy analysis method. Differences between the obtained solutions were slight. However, the advantage of the examined method is that we receive here the approximate solution in the form of continuous function which can be used then in a further analysis or to perform various simulations.

W artykule przedstawiono homotopijną metodę analizy równań opisujących drgania swobodne układu o jednym stopniu swobody opisane równaniami liniowymi oraz nieliniowymi.

Homotopijna metoda analizy daje możliwość poszukiwania rozwiązania szerokiego zakresu problemów opisanych za pomocą równań operatorowych. W artykule przedstawiono przykłady liczbowe w celu potwierdzenia dokładności i szybkiej zbieżności metody. W przypadku liniowym znane było dokładne rozwiązanie, dzięki czemu można było porównać je z rozwiązaniami uzyskanymi za pomocą analizy homotopijnej. Różnice między otrzymanymi roztworami były niewielkie. Zaletą badanej metody jest jednak to, że otrzymano przybliżone rozwiązania w postaci ciągłych funkcji, które można wykorzystać w dalszych analizach, w tym do interpretacji wyników badań doświadczalnych.

Authors: KORIS Kálmán , BÓDI István
Published: April 2019

The assembly of conventional shear reinforcement in concrete beams is usually a time and labour-intensive process which may reduce the effectiveness of the mass production of prefabricated elements. In addition to the application of stirrups, the shear strength of reinforced concrete beams can also be increased by using fibre reinforcement. The objective of our research was to find out, whether the use of appropriate fibre reinforcement could partially or fully replace the conventional shear reinforcement in prefabricated beams. Shear strength of several steel fibre reinforced, prestressed concrete beams with sparse stirrup spacing was tested. Analytical and numerical analysis of these beams were also carried out to investigate the effect of fibre dosage on their shear capacity, and the amount of steel fibre reinforcement that could replace conventional shear reinforcement was determined for the examined beams.

Wykonanie tradycyjnego zbrojenia poprzecznego belek żelbetowych jest zazwyczaj pracochłonnym procesem, który może obniżyć efektywność masowej produkcji elementów prefabrykowanych. Nośność na ścinanie belek żelbetowych może być zwiększona przez zastosowanie zbrojenia rozproszonego włóknami, jako uzupełniającego w stosunku do zbrojenia strzemionami. Celem przedstawionych badań było zbadanie, czy, przez użycie właściwego zbrojenia rozproszonego włóknami, można częściowo bądź w pełni zastąpić tradycyjne zbrojenie na ścinanie w belkach prefabrykowanych. W pracy zbadano nośność na ścinanie kilku prefabrykowanych belek żelbetowych zbrojonych włóknami stalowymi i przy rozrzedzonym rozstawie strzemion. Wykonano również obliczenia analityczne i analizy numeryczne belek porównawczych w celu określenia wpływu ilości dodatku włókien na nośność na ścinanie oraz w celu określenia ilości zbrojenia w postaci włókien stalowych, które umożliwia zastąpienie tradycyjnego zbrojenia na ścinanie dla zbadanych belek.

Authors: MLHEM Maiasa
Published: April 2019

According to the increasing demand of suitable soils under different types of foundation in the geotechnical engineering projects, many researchers try to find the best type of additives that improve the mechanical properties of soils. In addition, the small-strain stiffness is an important parameter for various geotechnical design applications. Therefore, I aim from this research to study the availability of Free–Free Resonant frequency method (FFR) in measuring the Young’s modulus and Poisson ratio for epoxy treated sand (ETS). Moreover, detecting the effect of the additives on the strength of treated sand by applying compression test on both types of treated specimens: cement treated sand (CTS) and (ETS), and then comparing between the results.

Next, the results have been analyzed and then Young modulus and Poisson ratio have been calculated. There was reversal relations between the both parameters according to the additives percentages, where E increased, Poisson ratio decreased. Then, the compression tests were applied on cylindrical specimens, the more additive percentages was the higher maximum load. The treated sand with epoxy percentage from 2% up to 5% was stronger than the treated sand with 50% cement.

Streszczenie

Zgodnie z rosnącym zapotrzebowaniem na przygotowanie odpowiednich gruntów pod różne typy fundamentów w projektach geotechnicznych, wielu badaczy próbuje znaleźć najlepszy rodzaj dodatków, które poprawiają właściwości mechaniczne gruntów. Ponadto zmienność sztywności w zakresie małych odkształceń jest ważnym aspektem dla różnych zastosowań w projektowaniu geotechnicznym. Stąd, celem wykonanych badań jest ocena przydatności metody FFR (Free-Free Resonant frequency) do pomiaru modułu Younga i współczynnika Poissona dla piasku poddanego obróbce epoksydowej (ETS). Dodatkowym celem badań jest ocena wpływu dodatków na wytrzymałość poddanego obróbce piasku w próbie ściskania na obu rodzajach poddanych obróbce próbek: piasku stabilizowanego cementem (CTS) i (ETS), a następnie porównanie wyników.

Po przeprowadzaniu analizy wyników badań, wyznaczono moduł Younga i współczynnik Poissona. Między obydwoma parametrami występowały relacje odwrotne w zależności od procentów dodatków, tzn. przy wzroście modułu E, współczynnik Poissona zmniejszał się. Następnie poddano ściskaniu próbki cylindryczne; przy większej zawartości dodatków, uzyskiwano większe nośności. Modyfikowany piasek z zawartością epoksydu od 2% do 5% okazał się być mocniejszy od piasku z dodatkiem 50% cementu.
