Published: December 2018

This paper presents the modeling, simulation, and control of a small-scale electric powered quadrotor tail-sitter vertical take-off and landing unmanned aerial vehicle. In the modeling part, a full attitude wind tunnel test is performed on the full-scale unmanned aerial vehicle to capture its aerodynamics over the flight envelope. To accurately capture the degradation of motor thrust and torque at the presence of the forward speed, a wind tunnel test on the motor and propeller is also carried out. The extensive wind tunnel tests, when combined with the unmanned aerial vehicle kinematics model, dynamics model and other practical constraints such as motor saturation and delay, lead to a complete flight simulator that can accurately reveal the actual aircraft dynamics as verified by actual flight experiments. Based on the developed model, a unified attitude controller and a stable transition controller are designed and verified. Both simulation and experiments show that the developed attitude controller can stabilize the unmanned aerial vehicle attitude over the entire flight envelope and the transition controller can successfully transit the unmanned aerial vehicle from vertical flight to level flight with negligible altitude dropping, a common and fundamental challenge for tail-sitter vertical take-off and landing aircrafts. Finally, when supplied with the designed controller, the tail-sitter unmanned aerial vehicle can achieve a wide flight speed envelope ranging from stationary hovering to fast level flight. This feature dramatically distinguishes our aircraft from conventional fixed-wing airplanes.

Published: December 2018

Intersectoral collaboration amongst health and other sectors, as well as between government and non-governmental organisations, has been highlighted as a way to improve health equity. We used a mixed-methods approach to assess collaborative relationships between multiple government sectors and civil society and to suggest possible health promotion interventions and policy alternatives for the urban poor in deprived neighborhoods. A total of 18 participants involved in health promotion interventions and policy processes related to the inner-city area of Seoul were recruited using purposive sampling methods. Participants included stakeholders working for or engaging in governments (3), public health care institutions (5), social service providers (3), community-based organisations (CBOs) (4) and faith-based organisations (3). We conducted semi-structured, one-on-one interviews and then collected survey data. Quantitative data were analysed using social network analysis, and qualitative data were analysed through iterative and consensus processes. The social network analysis indicated that a CBO plays the most substantial role in sharing and controlling informational resources to promote health. A stakeholder analysis showed that the CBO neutrally and negatively viewed the possibility of collaboration with other stakeholders. Three themes related to challenges to intersectoral collaboration emerged: (1) lack of trust and communication, (2) need of a coalition with a committed leading actor for future collaboration and (3) organisational and political silos within and across public sectors. Increased understanding of the current status of and challenges to collaboration can inform the planning and implementation of complex intervening strategies and policies tailored to vulnerable people in deprived neighborhoods. Community-led collaborative actions empower people in marginalised communities to envision a healthier community.
How I treat MDS after hypomethylating agent failure
Authors: Santini Valeria
Published: December 2018

Hypomethylating agents (HMA) azacitidine and decitabine are standard of care for myelodysplastic syndrome (MDS). Response to these agents occurs in ∼50% of treated patients, and duration of response, although variable, is transient. Prediction of response to HMAs is possible with clinical and molecular parameters, but alternative approved treatments are not available, and in the case of HMA failure, there are no standard therapeutic opportunities. It is important to develop a reasoned choice of therapy after HMA failure. This choice should be based on evaluation of type of resistance (primary vs secondary, progression of disease [acute leukemia or higher risk MDS] vs absence of hematological improvement) as well as on molecular and cytogenetic characteristics reassessed at the moment of HMA failure. Rescue strategies may include stem-cell transplantation, which remains the only curative option, and chemotherapy, both of which are feasible in only a minority of cases, and experimental agents. Patients experiencing HMA failure should be recruited to clinical experimental trials as often as possible. Several novel agents with different mechanisms of action are currently being tested in this setting. Drugs targeting molecular alterations (IDH2 mutations, spliceosome gene mutations) or altered signaling pathways (BCL2 inhibitors) seem to be the most promising.

Malaria remains a major global threat to human health and economic development. Microvascular lesions caused by Plasmodium falciparum–infected human erythrocytes/red blood cells are hallmarks of severe pathogenesis contributing to high mortality, particularly in children from sub-Saharan Africa. In this study, we used a phage display complementary DNA library screening strategy to identify P falciparum glutamic acid–rich protein (PfGARP) as a secreted ligand that recognizes an ectodomain of human erythrocyte anion-exchanger, band 3/AE1, as a host receptor. Domain mapping of PfGARP revealed distinct nonoverlapping repeats encoding the immune response epitopes and core erythrocyte-binding activity. Synthetic peptides derived from the erythrocyte-binding repeats of PfGARP induced erythrocyte aggregation reminiscent of the rosetting phenomenon. Using peptides derived from the immunogenic repeats, a quantitative immunoassay was developed to detect a selective immune response against PfGARP in human plasma samples obtained from patients in rural Mali, suggesting the feasibility of PfGARP as a potential biomarker of disease progression. Collectively, our results suggest that PfGARP may play a functional role in enhancing the adhesive properties of human erythrocytes by engaging band 3 as a host receptor. We propose that immunological and pharmacological inhibition of PfGARP may unveil new therapeutic options for mitigating lesions in cerebral and pregnancy-associated malaria.
A robust methodology for time picking and error analysis of ultrasonic waveforms and rock densities in the laboratory
Authors: Durán Evert L. , Adam Ludmila , Wallis Irene C.
Published: December 2018

The relationships between elastic wave speeds and rock physical properties are commonly studied through laboratory experiments. However, the estimation of elastic wave arrival times and the associated errors are not reported consistently. Changes in experimental conditions such as pressures or fluid substitution vary the arrival time and shape of the recorded ultrasonic signals. Crosscorrelation techniques are a simple way of estimating time differences between waveforms for a range of experimental conditions. However, in the presence of elastic wave attenuation, which results in the change of waveform shape (frequency content), this technique can be unstable. We design a methodology based on dynamic time warping functions for consistently picking arrival times between different ultrasonic waveforms. This methodology is robust to small changes in ultrasonic waveform shape due to variation in the experimental conditions. Here, we estimate and correlate P- and S-wave time picks for variations in (1) fluid type or saturation and (2) confining or fluid pressures. We also develop a semiautomated error analysis that uses Monte Carlo simulations to propagate uncertainty in time picks into wave speed and elastic moduli errors. We test the methodology on a set of volcaniclastic and intrusive rocks from a geothermal field in New Zealand at atmospheric conditions and confining stresses. The Python code for this analysis is freely available to the community.

The monograph is devoted to the development of a mechanism of interaction between the public and private sectors of the economy, which is aimed at making managerial decisions on the implementation of socially significant infrastructure projects, ensuring the creation of social, transport, engineering, manufacturing and other infrastructure at the Federal level, the level of subjects of the Russian Federation and municipal.
The book focuses on socially significant infrastructure projects in the social sphere, which provide for the creation of new, reconstruction of already created and the return of previously lost social infrastructure.
In developing the proposed mechanism of interaction of economic agents in the activities of real estate companies and administrations of the administrative-territorial formations, identifies the problems in realization of socially important projects for the development of social infrastructure, provides a mechanism for the selection of eligible applicants for the implementation of investment and other development projects for the creation of real estate objects for various purposes inclusive of mandatory social infrastructure development, the requirements for the necessary set of development and other investment companies on the structure of their assets, which are involved in the implementation of socially important infrastructure projects for the creation of socially-oriented objects, are formed.
Simulation of such interaction is carried out in the form of coalition-free games. Based on the results of the model are analyzed for the presence of strong Nash equilibria on the basis of the relevant procedures. To form a game that will present a situation of strong Nash equilibria, developed methods of correction of the institutional environment and prove the theorem about the existence of such factors of adjustment of the institutional environment that determine the existence of strong Nash equilibria.
The book analyzes the legal aspects of the implementation of socially important infrastructure projects, as well as provides an overview of international practices of their implementation.

A közelre mutató névmással bevezetett anafora antecedense tipikus esetben a megelőző mondat nem topik eleme. Ennek a használatnak azonban (1) vannak szabályai, illetve tendenciái és (2) nem kizárólagos érvényű, mert a magyar szövegben a megelőző mondat topikja is lehet antecedense a mutató névmással alkotott anaforának. A tipikus használat összefügg az anafora szintaktikai fókusz szerepével, emellett részben szemantikai, részben pragmatikai-stratégiai szabályok és tendenciák irányítják, összhangban a névmás kettős: kontrasztáló és azonosító jelentésével. A névmás használata befolyásolja a szöveg diszkurzív kontinuitását: a nem topik szerepű antecedensre visszautaló anafora egyes esetekben a beszélő kommentárját vezeti be az adott témához, a topik szerepű antecedensre visszautaló anafora pedig a beszéd témájának új irányát jelzi.

Authors: Šikl Matěj , Havlůj František
Published: December 2018

Procedure of criticality calculations and uncertainty evaluations currently has several insufficiencies which could lead to potential non–conservativeness. Paper discuss and describes possibilities of elimination of these insufficiencies and thereby ensuring safely sub–critical results of calculations. Selection of experiments for validation based on similarity coefficients between systems acquired from TSUNAMI-IP is used for this purpose. TSUNAMI-IP operates with sensitivity of multiplication factor to cross sections of individual isotopes and reactions between compared systems. Moreover, TSUNAMI-IP determines uncertainty of calculations brought in using insufficiently similar experiments. Within research, effects of variable parameters used in calculations inputs are investigated. In conclusion optimized suggested approach for validations and uncertainty evaluation using TSUNAMI module from SCALE based on knowledge acquired within research is described.
Why Can´t We Regard Robots As People?
Authors: Schmiljun André
Published: December 2018

With the development of autonomous robots, one day probably capable of speaking, thinking and learning, self-reflecting, sharing emotions, in fact, with the raise of robots becoming artificial moral agents (AMAs) robot scientists like Abney, Veruggio and Petersen are already optimistic that sooner or later we need to call those robots “people” or rather “Artificial People” (AP). The paper rejects this forecast, due to its argument based on three metaphysical conflicting assumptions. Firstly, it is the idea that it is possible to precisely define persons and apply the definition to robots or use it to differentiate human beings from robots. Further, the argument of APs favors a position of non-reductive physicalism (second assumption) and materialism (third assumption), finally producing weird convictions about future robotics. Therefore, I will suggest to follow Christine Korsgaard’s defence of animals as ends in themselves with moral standing. I will show that her argument can be transmitted to robots, too, at least to robots which are capable of pursuing their own good (even if they are not rational). Korsgaard’s interpretation of Kant delivers an option that allows us to leave out complicated metaphysical notions like “person” or “subject” in the debate, without denying robots’ status as agents.
An Empirical Study on Chinese And American College Students’ Moral Value Recognition
Authors: Hailong Zhu
Published: December 2018

This study used a self-designed questionnaire to empirically evaluate Chinese and American undergraduate students’ recognition of moral values in six dimensions: honesty, civility & self-discipline, benevolence, unity & helping others, esteem, and filial piety. In total, 743 valid samples from 8 Chinese universities and 157 valid samples from 4 American universities were collected for an experimental comparison. Measurement results showed that the differences between Chinese and American college students were not significant in the dimensions of honesty, benevolence, esteem, and filial piety. These values, which originated in traditional Chinese culture, had the same priorities in both groups, confirming a certain degree of universality. However, significant intergroup differences existed in the civility and self-discipline dimension and the unity and helping others dimension. These results highlight the importance of enhancing Chinese college students’ moral consciousness, especially with esteem, and of enhancing American students’ consciousness of unity and helping others.
The Categorical Imperative in Defence of Animal Rights. Christine Korsgaard’s Ethical Extensionism
Authors: Adamska Małgorzata
Published: December 2018

In this paper, I present Christine Korsgaard’s style of building a conception of animal rights protection based on a concept of Kantian provenance, namely “end in itself”. Considering that an end in itself in Immanuel Kant’s philosophy includes only human beings, the American philosopher needed to modify (extend) the meaning of the abovementioned concept. This study aims at showing this change of the meaning in categories derived from Fregean semantics (sense and reference). Moreover, I will attempt to prove that by broadening the extension of “end in itself” Korsgaard uses a strategy called ethical extensionism and situates the revised (naturalized) categorical imperative ipso facto within environmental ethics.I start with elucidating Korsgaard’s views on the meaning of “end in itself” before she took interest in animal rights (set out mainly in Kant’s Formula of Humanity and The Sources of Normativity) and then I synthetically describe her animal rights philosophy with a special regard to the category of “natural good”. The second part of the article explains the methodology used in the paper, while the last part is intended to be an interpretation of Korsgaard’s thought.
Mixture and Transformation in Aristotle’s De generatione et corruptione
Authors: Zarifian Arman
Published: December 2018

In his works on natural sciences, primarily in the Physics, Aristotle focuses on different forms of metabolē and distinguishes movement in general from substantial change. The On generation and corruption deals with the latter. When reading this treatise, one should pay particular attention to the concept of mixture. Apart from being the subject of a specific chapter (I 10), the problem of mixture permeates the whole work. But what exactly is mixture? Is it a simple combination of small parts? Can a compound of water and wine be called mixture? If so, is this mixture and nothing more? In the course of the discussion, it is argued that the Aristotelian idea of mixis does not correspond to the concept that is usually associated with it. Rather, it is shown that mixis is fundamental for comprehending the physical world and constitutes not only the term per quem the first elements of all material bodies originate, but also plays a fundamental role in all natural sciences, particularly, in biology.
The Analytical Perspective of Aristotle’s Categorical and Modal Syllogisms
Authors: Wesoły Marian Andrzej
Published: December 2018

What is meant under the genuine title of Aristotle’s ta Analytika is rarely properly understood. Presumably, his analytics was inspired by the method of geometric analysis. For Aristotle, this was a regressive or heuristic procedure, departing from a proposed conclusion (or prob­lem) and asking which premises could be found in order to syllogize, demonstrate or explain it. The terms that form categorical and modal propositions play a fundamental role in analytics. Aristotle introduces letters in lieu of the triples of terms (major – middle – minor) constitut­ing the propositions and the three syllogistic figures that schematize them. His formulation of the three syllogistic figures refers to a syntacti­cal and predicative order and position of the triples of terms, arranged in some diagrammed schemata, which, regrettably, are missing from the extant text of the Prior Analytics. Considering planar and graphic arrangements, both vertical and horizontal orders as well as the posi­tion of the three terms involved, we propose a reconstruction, at least to some extent, of these probable lettered diagrams. In such reconstructed diagrams, we can appropriately capture the definition of syllogism as a predicative connexion of terms, and easier survey a synoptic account of all valid predicative relations and transpositions, and also reduce the imperfect syllogisms into the moods of the first figure. Aristotle’s syllogistic is an analytical calculation of terms, understood as predicates and subjects within the categorical propositions, and more precisely of three terms schematized in three figures in predicative links such that, by means of a middle, follows from necessity a conclusion of the extreme terms. The necessity of the consequence is not based on the implication or inference of the propositions, but on a predictive transi­tivity through the middle term within the syllogistic figures. Syllogism must draw its conclusion through the way its terms are predicated of one another. Aristotle in his Prior Analytics (I 3, 8–22) developed also a complex account of modal syllogisms within necessity and possibility of belonging (predicating). This account involves also such an analyti­cal reduction to the syllogistic figures. In this analytical perspective, we try to throw some light on his modal syllogisms, although this difficult and nowadays thoroughly discussed topic would require a much wider treatment.
Koinon and koinônia: A Particular Case of Participation in John Philoponus
Authors: Granata Daniele
Published: December 2018

The aim of this study is to discuss an original philosophical contribution made by Philoponus, who in In Cat. 18, 14–22 equates koinon in its most peculiar meaning with the concept of koinônia understood as a particu­lar case of Platonic methexis. First, the paper analyzes the passages where the Neoplatonic commentators of the Categories distinguish four distinct meanings of the Aristotelian concept of koinon. Subsequently, this article emphasizes the differences between Philoponus’ herme­neutical suggestions and those of the other commentators. Philopo­nus clarifies that while every koinon is methekton, Aristotle’s koinon is characterized by the fact that the participation is ex isou and kata meros. Thus, koinônia, according to Philoponus, is a particular case of methexis, where everyone participating in something participates in it equally and singly. The example cited by Philoponus to explain Aristotle’s koinon is that of men participating equally and singly in human nature. The study concludes with a discussion of the relationship among the concepts of koinon, koinônia and methexis.
Czas w demokratycznym systemie parlamentarnym. Przypadek Sejmu RP w latach 1989–2015
Authors: Kasianiuk Krzysztof
Published: December 2018

Niezależnie od perspektywy teoretycznej, aspekt czasu jest odnotowywany właściwie w każdym studium dotyczącym ewolucji systemów politycznych. Ma on szczególne znaczenie w analizach systemów przechodzących od autorytaryzmu do demokracji. Dotyczy to wielu systemów parlamentarnych, tj. opartych na mechanizmach periodycznych wyborów do ciał przedstawicielskich. Jednak stosunkowo mało uwagi poświęca się zagadnieniu czasu w polskiej literaturze politologicznej. Celem artykułu jest prezentacja wyników badań nad wykorzystaniem czasu w polskim Sejmie w latach 1989–2015, tj. w kadencjach X–VII. Czas był analizowany w sensie fizycznym i organizacyjnym. Na podstawie oficjalnych danych Sejmu RPzbadano dynamikę wykorzystania czasu m.in. poprzez analizę liczby dni obrad i długości posiedzeń. Wyniki badań wskazują, że cechą charakterystyczną badanego okresu jest zmienna dynamika wykorzystania czasu w Sejmie. Ważny wydaje się w tym przypadku zwłaszcza okres między IV i V kadencją.

Traveling through narrative time: How tense and temporal deixis guide the representation of time and viewpoint in news narratives
Authors: Sanders José , van Krieken Kobie
Published: December 2018

This study examines the linguistic construal and cognitive representation of time and viewpoint in the genre of news narratives. We present a model of mental spaces that involves a News Space in which the deictic center is construed of the news actors at the time the newsworthy events took place, and a Reality Space in which the deictic here-and-now center of journalist and reader is construed. This model explains how the dynamic representation of narrative news discourse, characterized by shifts in time and viewpoint, is steered by linguistic devices. An analysis of Dutch news narratives shows that temporal adverbs such as yesterdayand shifts from present tense to past tense may signal a moveforwardin narrative time, to a viewpoint in the future relative to the narrative now-point, rather thanbackward. These atypical time shifts can be accounted for by presupposing an Intermediate Space located at a point in time between the News Space and the Reality Space where the progression of narrative time comes to a halt and experiences are rather relived than reported. The salience of the Intermediate Space may be signaled by quotative conditionals reflecting the viewpoints of implicitly quoted sources. These results clarify how tense and temporal deixis steer the linguistic construal of time and viewpoint in news narratives, demonstrating that time and viewpoint are closely linked in the cognitive representation of these narratives.
Application of Adaptive Feedforward-Feedback Control on Multiple Effect Evaporator Process
Authors: Matheus Mota Sousa Felipe , Rodrigues Fonseca Rodolpho
Published: December 2018

Evaporation is one of the most standard procedures in many industrial processes. Although its importance, this operation is quite expensive and, to minimize costs, it is applied multiple effect evaporators. In terms of process control, this configuration is more susceptible to disturbances and also more complicated to control due to process non-linearity. In this paper, a two effects evaporator in a feedforward pattern of feeding was controlled by different adaptive strategies of regulatory control. It was developed feedback and feedforward-feedback control loops in which their PID and lead-lag control parameters were modified according to a gain scheduling strategy based on process variable value. It was shown that adaptive strategy used in feedback control led to a better performance against non-adaptive control, reducing ISE, IAE and ITAE criteria by 12.60%, 7.86% and 13.98% respectively, but also the settling time. However, the final control element was affected leading to 59.77% increase of control effort (ISU). On the other hand, feedforward-feedback allowed even more disturbance rejection than adaptive feedback. As example, IAE values were reduced by 29.96% and 48.17% for feedforward-feedback using non-adaptive and adaptive lead-lag control, respectively. Although their better performance, both feedforward-feedback loops increased control effort, reaching even 70 times of feedback ISU value.
Effect of Ultrasound on Heat Pump Drying Characteristics of Pea Seeds
Authors: Tao Zhichao , Yang Zhao , Yu Fei , Yang Zongyu
Published: December 2018

For the purpose to study the effect of ultrasound treatment on heat pump drying, the experiments were conducted on pea seeds at drying temperature of 30, 35 and 40 °C , ultrasound power of 0, 60 and 100 W and frequency of 0, 28 and 40 kHz. The influence of ultrasound and temperature on the drying process was studied by analyzing the drying characteristics of pea seeds. The results demonstrated that increasing the ultrasound power, frequency and drying temperature can improve the drying rate and the Midilli model can describe the drying kinetics of pea seeds well. The effective moisture diffusion coefficient increased with the increase of ultrasound power, frequency and drying temperature, while there was no obvious trend for the change of seed activation energy under different conditions. The seed viability was promoted with the raise of ultrasound power and fell when increasing drying temperature.

This amplifier was able to reach transmission distance ratio of 160:5 km for GPON:FSO. Moreover in this paper, was study different characterizations of EYDWA amplifier, which depend essentially on the opt-geometric parameters, such as concentrations of ions erbium, length of the waveguide amplifier and the effect of those parameters to optimize the gain G, quality factor Q, min of BER and eye diagram.
“Get the Tone Right”: Reading with the Realism of Object-Oriented Ontology
Authors: Wei-Hao Chin Gabriel Patrick
Published: December 2018

This paper investigates the consequences of taking seriously the metaphysics of Object-Oriented Ontology (OOO), as defined by Graham Harman, in the field of literature. Acutely focusing on just one possible mobilisation and application of the theory, the essay deploys OOO to read two major writers of the late 20th century, Don DeLillo and Murakami Haruki, in novel configurations made possible by applying an Object-Oriented method to the genre of Magic Realism. Using this method, the essay unearths an unarticulated avenue for studying the genre and these authors against established national, cultural, and canonical boundaries in literature, putting into conversation various literary traditions based on formal characteristics found in the texts through OOO’s metaphysics, and suggesting wholly untested paths for literary study in the wake of Object-Oriented philosophies.
Data as Word
Authors: Rosenberg Daniel
Published: December 2018

The history of what we today call “data” extends to the ancient world, yet our contemporary terminology of “data” is modern. This article examines the history and significance of the term “data.” It argues that a historiography of data that is self-conscious about the historicity of its own categories can illuminate the specific materiality of data, distinct from the things in the world it claims to represent. This essay is part of a special issue entitled Histories of Data and the Database edited by Soraya de Chadarevian and Theodore M. Porter.
Role of Carbohydrate and Dietary Fibery for Soccer Players
Authors: Yustika Gaung Perwira
Published: December 2018

Soccer is the most well known and a phenomenal sport in the world, with around 270 million players registered to this game (FIFA, 2015). Soccer has already attracted attention either sport scientist and government from many countries to promote the benefit of active physical activity and also maintained people’s health, including the minorities and poorest. (Hammami et al, 2016; Milanovic et al., 2015; Parnell et al., 2016). Furthermore, this sport can be used to support the health public program in order to prevent chronic diseases due to cause lack of physical activity (Krustrup et al., 2010).Quality food choices and adequate nutrition nutrient are important for supporting training program and enhancing the physical performance of professional athletes. Macronutrients provide the metabolic substrates necessary for producing the chemical energy required for skeletal muscle contraction and cardiovascular physiology, while the micronutrients help the metabolic reactions involved in energy production and gas transport in the circulation. Soccer is a sport requiring for both aerobic dominant and also anaerobic energy. It needs the players to exercise repetitively at high intensities using large muscle groups for periods of several seconds to several minutes for the full match (90 min) plus added time. Metabolically, athletes depend to a certain extent on their endogenous glycogen stores in the liver and skeletal muscles. Besides from genetic factor, talent and the effort of training, it has been acknowledged that no single factor plays a bigger role in maximaxing physical performance than dietary plan.This Review article was made to show the important role of carbohydrate and dietary fiber in the aspect of soccer game, resumed from scientific articles especially from Europe/USA where soccer was more advanced there. The writer hoped that this article written and published at Indonesia can be used to developed sport science and sport medicine for his beloved country.
Necrophagous flies assemblages: Spatio-temporal patterns in a Neotropical urban environment
Authors: Battan-Horenstein Moira , Gleiser Raquel Miranda
Published: December 2018

Species composition, richness, and relative abundance of the communities of Calliphoridae, Muscidae, and Fanniidae in Córdoba city, Argentina was assessed, and how these characteristics are affected by seasonal and anthropogenic conditions was studied. The study was carried out in thirteen sites with various levels of urbanization during 2014 and 2015, comparing two seasons: the warmer-wet summer and the cold-dry winter. Adult flies were collected in each site using two traps baited with hydrated bone meal. A total of 1683 flies were collected, belonging to twelve genera and 22 species. Several of the species collected are relevant to forensic sciences. The most frequent species were Hydrotaea aenescens (Muscidae) and Fannia fusconotata (Fanniidae). No differences in necrophagous fly richness or relative abundances between the central urban sites and the periphery suburban sites were observed; however, richness was significantly correlated with local (250 m buffer area) built-up density. Species composition differed between the urban and suburban sites. Seasonal differences were also detected: the relative abundances per species were more even in the summer. Dissimilarities in the assemblages were mainly due to differences in the relative abundances of some species, reflecting their adaptability to landscapes with different degree of urbanization. Regardless of season or urbanization density, species richness and effective number of species were higher in traps placed in the sun as opposed to shade. Taken together, these results suggest that in Córdoba city both landscape and local factors explain variations in the necrophagous fly community.
The identity of two of Azara’s “mystery” waterbirds
Authors: Smith Paul
Published: December 2018

The identity of two birds described from Paraguay by Félix de Azara as No. 378 “Ypacahá jaspeado encima” and No. 402 “Chorlito pies roxos” is elucidated for the first time. No. 378 refers to Ocellated Crake Micropygia schomburgkii and is the basis for the name Rallus maculosus of Vieillot, 1819. Rallus maculosus Vieillot, 1819, is a nomen oblitum, unavailable for application. No. 402 is referable to Ruddy Turnstone Arenaria interpres morinella and is the basis of the name Totanus nigellus Vieillot, 1816. Totanus nigellus Vieillot, 1816 is thus a junior synonym of Arenaria interpres morinella (Linnaeus, 1766) and available for application.

Abstract:

Introduction: Morphology and function of the mitral annulus (MA) shows alterations in different valvular (for instance in mitral regurgitation) and non-valvular disorders (for instance in certain cardiomyopathies, cardiac amyloidosis). Aim: The aim of the present study was to examine the relationship between MA morphologic and functional properties and three-dimensional speckle-tracking echocardiography- (3DSTE) derived left ventricular (LV) ejection fraction (EF) in subjects with normal versus borderline LV-EF. Method: The present study comprised 146 volunteers (mean age: 32.0 ± 11.4 years; 74 males) in whom complete two-dimensional Doppler echocardiography was performed with a negative result extended with 3DSTE. The population was further divided into two groups according to their 3DSTE-derived LV-EF (borderline 50–54% versus ≥55%). Results: In cases with borderline LV-EF, higher LV end-systolic LV volumes and lower LV longitudinal strain could be measured. All end-systolic and end-diastolic MA diameter, area and perimeter data proved to be higher in cases with borderline LV-EF. In these subjects, MA functional parameters proved to be lower as well. In contrast, LV-EF showed correlations neither with end-systolic and end-diastolic MA dimensions nor with MA functional parameters. Conclusions: 3DSTE-derived borderline LV-EF is associated with MA dilatation and functional impairment. Orv Hetil. 2018; 159(50): 2129–2135.

Abstract:

Introduction: Being entitled for no patient co-payment, the Hungarian reimbursement condition of analogue insulins as part of basal-bolus treatment in type 2 diabetes mellitus (T2DM) requires that two HbA1c levels should achieve <8.0% target value within 12 months (measured two months apart) after switching from treatment with human insulins. Achieving this target, the treatment should be considered effective from drug reimbursement perspective. Aim: The aims of the study were to investigate the effectiveness of insulin glargine + insulin glulisine basal-bolus regimen from the payer’s perspective and to investigate the ability to maintain the achieved glycaemic control in previously uncontrolled T2DM patients (HbA1c >9.0%). Method: This one-year, non-interventional study included patients with T2DM inadequately controlled (HbA1c >9.0%) on previous human basal-bolus treatment. The main outcomes were the proportion of patients who achieved the adequate glycaemic control (defined by the reimbursement rules) and the proportion of patients who achieved reimbursement rules defined HbA1c <8.0% target value by the 6 months after switch and could maintain this glycaemic control for upcoming further 6 months. As safety outcome, the hypoglycaemic events were recorded. Results: Out of the 557 patients enrolled, 287 had available data to be included in the efficacy analysis. Out of the 287 efficacy analysis patients, 169 (58.9%) achieved the reimbursement rules defined glycaemic control. At 6 months, 167 patients had HbA1c value <8.0% and 152 (91.0%) remained in this target range until the end of the 12-month observational period. Overall, 1221 non-severe and 6 severe hypoglycaemic events were reported. Conclusions: More than half of the patients with T2DM who were newly switched to insulin glargine + glulisine basal-bolus treatment could achieve the reimbursement rule criteria requiring for prescription of the analogue insulins with no co-payment beyond 1 year of treatment in Hungary. However, the results revealed that glycaemic control assessment with HbA1c measurements had not met the reimbursement requirements in a significant part of patients.

Cytokinin (CK) is an important phytohormone, which not only plays significant role in plant development but also involves in mediating plant stress tolerance. Previous studies showed that the drought tolerance can be improved by stress-inducible overexpression of adenine isopentenyl transferase (IPT), which is a critical enzyme in CKs biosynthesis. To study the role of soybean GmIPT10 in regulating plant tolerance, we successfully generated GmIPT10-overexpressing transgenic soybean plants and screened a line carrying homozygous, single copy of transgene. Analyzing several physiological traits of this line demonstrated that it possessed stress tolerance characteristics, including increased primary root and shoot lengths, better production of shoot biomass, higher number of trifoliate leaves, and higher survival rate than the non-transgenic plants under drought condition. The net house experiments also showed that the GmIPT10-overexpressing transgenic soybean had a greater relative water content compared to the control genotype under applied drought condition. Therefore, this report indicated that plant drought tolerance might be enhanced via regulating expression of GmIPT10.
Methods of Detecting Meat Species in Food of Animal Origin

An important factor in the detection of falsification is the control of the composition of the meat at each stage of manufacturing the product. The PCR method is based on the study of proteins and meat nucleic acids used in food for the detection of animal species. Another technique is the Elisa method that works on the principle of identification and measurement of the quantity of molecules in a sample. There are several types of Elisa to increase specificity due to differences in structure and sample characteristics. By comparing the two methods used to identify the processed meat product species, Real Time PCR had the highest prediction as results. However, the Elisa method is more time efficient and easier to use. Real Time PCR is effective in identifying processed meat products that require low detection. The Elisa Kit is useful because of the ease of use.
Hand health for all: Do undergraduate occupational therapy hand curricula respond to the call?
Authors: van Stormbroek Kirsty , Buchanan Helen
Published: December 2018

The call for higher education curricula to be responsive to the South African context is growing louder. Injuries to the hand are common in South Africa and intervention is often provided by novice occupational therapists who may work in complex practice contexts with limited supervision. Comprehensive hand health practice addresses both the biomedical and occupational dimensions of the human hand. Undergraduate education programmes should be responsive to this reality in preparing graduates adequately for hand practice. This article describes the content of hand curricula within occupational therapy undergraduate programmes in South Africa with the purpose of considering how they prepare graduates for the practice realities they may face during community service. A descriptive cross-sectional survey design was used with an online questionnaire aimed at determining the nature and extent of hand curricula presented in South African undergraduate occupational therapy programmes (n=8). Data were analysed using Stata 12. Time allocated to hand impairments varied considerably across universities. While assessment of biomedical performance components were taught by all universities, the occupational perspective was limited. The range and number of hand conditions and treatment modalities that were taught also varied. Findings are discussed against the contextual realities of practice in South Africa, primary health care policy, and national and international minimum standards for the education of occupational therapists. Core aspects of a hand curriculum are proposed as a means to enhance comprehensive hand health practice. Key words: Hand practice, occupational therapy education, hand health
