Gender, Genre, and Succession: Reception of Statius’ Achilleid in Baroque Opera
Authors: Škraban Kajetan
Published: October 2018

The paper examines the reception of the Achilleid, an epic fragment by the Flavian poet Statius, in the Baroque opera. The Achilleid weaves unique connections among the issues of gender, succession, and genre, and as such merits an important place in studying the operatic reception of antiquity. The elements mentioned above (gender, succession, genre, as well as transvestism etc.) have been significant in establishing the opera as an art form; indeed, in the light of their historical influence some of the operatic works inspired by Statius may be perceived as major, well-nigh constitutive building blocks of the operatic art.

Σρέτσκο Κοσοβέλ: Κονς και άλλα ποιήματα
Authors: Unuk Lara
Published: October 2018

Konec leta 2017 je pri založbi Vakhikon v Atenah v zbirki Poezija vsega sveta izšel knjižni prevod izbora Kosovelovih pesmi, Kons in druge pesmi, izpod peresa dveh prevajalcev mlajše generacije, Lambriane Ikonomu in Mihalisa Papandonopulosa. Izdajo je s slovenske strani podprl Trubarjev sklad. Izbor, ki naj bi, kot je navedeno v knjigi, nastal na podlagi Zbranih del Srečka Kosovela iz leta 1977, je – sodeč po siceršnji specializaciji obeh prevajalcev – najverjetneje preveden iz angleščine, čeprav v knjigi tega podatka ni. Zbirka predstavlja prvo knjižno objavo Kosovelovih pesmi na grških tleh in torej grškim bralcem omogoča prvo srečanje s pesnikom, zato nas še posebej zanima, kakšno podobo Kosovela prinaša in katere aspekte njegove ustvarjalnosti postavlja v ospredje.
Kodno preklapljanje v Ciceronovih pismih Atiku
Authors: Počkaj Mateja
Published: October 2018

Članek osvetljuje pojav kodnega preklapljanja v latinščini, pri čemer se osredotoča na Ciceronova pisma Atiku. Zmotno je prepričanje, da je dvojezičnost moderen pojav, saj je že v antiki izpričana v številnih literarnih in neliterarnih dokumentih. Dokaz, da sta bili grščina in latinščina kot najbolj razširjena in izpričana jezika v tedaj poznanem svetu v nenehnem stiku, so številni pisni viri, ki odražajo položaj, pomen in prestižnost enega in drugega jezika v različnih slojih antičnih družb. Zanimiv primer izposojanja je kodno preklapljanje, katerega najbolj znani primer je Ciceronova literarna zapuščina (zlasti njegov korpus zasebnih pisem). Pri njem je grščina jezik intimnosti, znak intimnega odnosa s sogovorcem (najpogosteje je to Ciceronov prijatelj Atik), dokaz kulturne superiornosti in izobraženosti, hkrati pa način ohranjanja distance do izrečenih trditev. Članek z vidika modernega razumevanja dvojezičnosti in kodnega preklapljanja pojasnjuje omenjene pojave v izbranih Ciceronovih pismih.
Espacio, Forma y Estructura en la casa 50x50' de Mies van der Rohe
Authors: Díaz Segura Alfonso , Serra Soriano Bartolomé , Meri de la Maza Ricardo
Published: October 2018

During the American stage of Mies the beauty of the constructive precision and the essentiality of space is emphasized, which subordinates the program to formal purity. Form is not invented, nor is it the corollary of function or technology, but is the result of placing transcendent and timeless values on secondary issues. The architect must establish an order that assures the formality of the work, but in modernity the systematic classicist rules no longer run. So the goodness of the result is a consequence of the ability of the architect and the user to share visual codes. The effort of Mies in this stage will be to establish certain certainties, universal and clear, developed around the relation among space, structure and shape. The Fifty by Fifty feet house marks a turning point in these intentions and points the path of his latest works.

La musicalización diegética de la crisis en el cine negro holliwodiense de los años 40. La música clásica como signo del conflicto
Authors: García Martín Judith Helvia
Published: October 2018

El estado de crisis es inherente en el cine negro: social, política, moral… son representadas en un género que se alimentó del bagaje cultural aportado por directores cuya procedencia centroeuropea y ascendencia judía condicionaron los recursos narrativos y estéticos que se utilizarían para plasmar el drama y angustia propios del film noir. Uno de los elementos de representación de estas crisis fue la música, tanto incidental como diegética. Sin embargo, por el carácter eminentemente realista de este cine, prestaremos atención a la segunda y, concretamente a la que habitualmente se denomina música clásica. Tras el visionado de una muestra de 50 películas de la era dorada del cine negro holliwoodense, observamos que esta música se emplea como elemento de representación de crisis culturales, sociales y personales, y su uso funcional juega un papel en la pervivencia del canon musical interpretativo, así como de los valores asociados a su significado
Hacer, explicar, enseñar cine. Didáctica y epistemología de la creación fílmica
Authors: Lázaro López José Ángel
Published: October 2018

La relación entre teoría y práctica en los estudios académicos cinematográficos sufre un estado de segregación y distanciamiento que es causa y efecto de una profunda crisis de entendimiento entre académicos y cineastas. Sin embargo, esta crisis no puede afrontarse, en primer lugar, desde la asunción de esa dicotomía intelectual entre el ellos y el nosotros ―desde dondequiera que se sitúe la otredad en el enfoque―, ni tampoco desde la observación de ningún conflicto radical entre ambos mundos profesionales del cine, ya que ese conflicto, al menos de forma manifiesta, no existe. ¿Qué perspectivas didáctica y epistémica genera esta situación de cara a los estudios fílmicos y cinematográficos? ¿Cómo se puede enseñar cine en estas circunstancias? En el presente artículo se analiza esta controvertida situación y se acentúa la necesidad de romper esta dicotomía para resituar el foco de atención en las condiciones necesarias y existentes para explicar y poder trascender, desde una perspectiva epistémica y sustancialmente didáctica, esa aparente distancia entre dos caras de una misma moneda que llamamos cine.
El proyecto fílmico y la teoría general de la producción
Authors: Alonso García Luis
Published: October 2018

Todo “mundo” construye relatos y mitos en torno a su origen y designio. Pero las facultades de comunicación y las escuelas del cine deberían ir más allá de esas leyendas y arcanos al describir e interpretar el “hacer fílmico” y el “saber sobre ese hacer”, lejos de las alusiones a los “misterios de la creación” o las “rutinas de la fabricación”. Partiendo del ámbito de la Dirección de Proyectos y la Administración de Organizaciones, planteamos la centralidad del concepto y marco de la “producción” como vía de escape de la (aparentemente) irresoluble contradicción entre lo estético y lo económico, entre la estandarización de los procesos y la singularidad de los productos. Solo así el concepto de “proyecto” cobra el sentido que debería tener en las praxis fílmicas.
The Relationship Between Levels of Stress and Academic Performance Among University of Nairobi Students
Authors: Oketch-Oboth Josiah W.B , Okunya Luke Odiemo
Published: October 2018

The study investigated the relationship between stress and academic performance among government-sponsored undergraduate students from the University of Nairobi in Kenya. The mediating roles of the students’ age, gender, locus of control, level and course of study in the relationship between stress and academic performance were also examined. The sample consisted of 319 male and 265 female students selected using stratified random sampling techniques, from all the six colleges of the university. The study was carried using a cross-sectional survey design involving levels one to five of the academic programs. Data was collected using questionnaires that measured stress and locus of control. Academic performance was assessed from the students’ academic transcripts. Both descriptive and inferential statistics were used for data analyses. Two-way and three-way chi- square statistics were used to test the statistical significance of the hypothesis.. The analyses were done using the Statistical Package for Social Sciences (SPSS) computer program. Regression analysis was conducted to find out how the confounding variables contributed to the relationship between stress and academic performance. Results showed that most of the students (64.4%) reported that they experienced between moderate to high levels of stress while just over a third (35.6%) reported low stress levels. The relationship between stress and academic performance was statistically significant (χ2=9.49, N=584, df=4, p=0.048). The relationship between stress level and academic performance was significant within 19 to 22 years, 23 to 26 years, males, females, College of Humanities and Social Sciences, College of Agriculture and Veterinary Sciences, levels one and four of study, internal locus of control, and external locus of control. Regression analysis showed that the higher the stress level, the poorer is the academic performance. However, only course/college appears to have statistically significant effect on the relationship between stress and academic performance. The cofounding effect on the stress and academic performance is complex and needs further investigation. The findings indicate the need for relevant authorities to institute programs that will lower the experience and effects of stress among university students. Further research is recommended to investigate the areas where the results were not significant.

Authors: Liang Foo See , Pathak Shaakalya
Published: October 2018

The People’s Republic of China (China) is a key leading economy in the Asia Pacific region. This study examines the relationship between the financial health, as measured by the Altman Z-Score, and corporate performance, as measured by the Return on Equity (ROE), of listed manufacturing companies in this market. A linear regression has been conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a five-year period have also been analysed. The analysis covers the period from 2013 to 2017 (inclusive) and yields a statistically positive correlation between ROE and the Z-Score for the market. China registered moderate-to-strong mean and median Z-Scores. These findings further support the strong economic position of this market as an Asian giant.
FORMAS FARMACÊUTICAS SEMISSÓLIDAS A BASE DE PAPAÍNA – AVALIAÇÃO PRELIMINAR DA ESTABILIDADE, CONTAMINAÇÃO MICROBIOLÓGICA E ATIVIDADE ENZIMÁTICA
Authors: BORELLA Júlio Cézar , TEIXEIRA Juliana Coelho Lopes , PUGA Robison Leandro Aparecido , STEVANATO Marise C. Bastos
Published: October 2018

Géis (usando carbômero) e cremes (usando base autoemulsionante aniônica), contendo 2% (p/p), 6% (p/p) e 10% (p/p) de papaína, são utilizados para fins de cicatrização e desbridamento de ferimentos. Com estas formulações, armazenadas em dois ambientes (5-10 ºC e 30-35 ºC), durante 4 meses, foram realizadas análises (pH, análise organoléptica, espalhabilidade, análise microbiológica, teste de centrifugação e atividade enzimática) para avaliar estabilidade, contaminação por micro-organismos e ação proteolítica. Os resultados mostraram que, para ambas as formas farmacêuticas, em temperaturas mais elevadas, houve maior rapidez na perda da atividade enzimática. Géis com altas concentrações de papaína (10% p/p) são inviáveis, pois apresentaram espalhabilidade anormais. Os cremes com papaína, em todas as concentrações, apresentaram separação de fases pelo teste de centrifugação, mostrando instabilidade termodinâmica. Os cremes (6% p/p e 10% p/p) apresentaram decréscimo intenso e rápido (entre 24 horas a 1 semana após preparo) da atividade enzimática, inviabilizando seu uso por períodos prolongados. Resultados de pH e contaminação microbiológica não foram determinantes para reprovação das formulações.  Sendo assim, o gel a 2% (p/p) foi a única formulação que não apresentou problemas críticos de estabilidade e perda de atividade enzimática, se for mantido entre 5-10 ºC.

QUÍMICA NA PRÁTICA: DIVULGANDO A QUÍMICA NAS ESCOLAS
Authors: Mello Regina Maria Queiroz de , Micaroni Liliana , Cunha Mariana Marques da
Published: October 2018

Sabe-se que as atividades experimentais permitem uma melhor visualização na prática do que os alunos aprendem nas aulas teóricas, o que os possibilita uma maior compreensão dos conteúdos de química. No entanto, muitas escolas públicas não apresentam condições de ofertar atividades experimentais devido à carência de material, escassez de tempo ou dificuldade por parte dos professores para preparar as aulas. O projeto visa minimizar essa falta de atividades experimentais nas escolas de ensino públicas através do uso de experimentos demonstrativos de química. Tais experimentos são selecionados e confeccionados por estudantes voluntários de graduação da UFPR, de diferentes cursos (química, engenharia química e farmácia) sob orientação das professoras coordenadoras do projeto. Através do agendamento de visitas, são apresentados para estudantes e professores do ensino médio dessas escolas 5 kits de experimentos num sistema de rodízio. Os estudantes voluntários da UFPR explicam e instigam a curiosidade dos estudantes da escola sobre o tema de cada kit. Até o momento, foram atendidos 609 estudantes de 3 escolas públicas. O projeto contribuiu para divulgação da química entre os estudantes do ensino médio despertando um maior interesse por essa disciplina e contribuiu para o processo de formação acadêmica e cidadã dos estudantes de graduação envolvidos no projeto.
The Accuracy and Clinical Utility of Intraoperative Frozen Section Analysis in Open Biopsy of Bone
Authors: Wallace Matthew T. , Lin Patrick P. , Bird Justin E. , Moon Bryan S. , Satcher Robert L. , Lewis Valerae O.
Published: October 2018

Background:

Open biopsy of bone is the diagnostic benchmark for the diagnosis of skeletal lesions. Intraoperative pathology consultation with frozen section analysis is commonly performed to confirm adequacy of lesional tissue and guide intraoperative decision making. The purpose of this study was to determine the accuracy and clinical utility of intraoperative frozen section during open bone biopsy.

Methods:

A retrospective review of 485 open biopsies of osseous lesions from 474 patients between 1997 and 2014 was performed. Pathology reports, operative notes, and prebiopsy imaging were assessed to determine the accuracy rates of frozen section analysis compared with final pathology. Pearson chi-squared and Fisher exact tests were performed to compare the accuracy and clinical utility rates based on soft-tissue extension, previous biopsy, lesional consistency, disease, and location.

Results:

Overall diagnostic yield of open bone biopsy was 95.3%. Frozen section analysis was accurate in 54.2%, equivocal positive in 21.2%, equivocal negative in 21.0%, and incorrect in 3.5% of cases. Previous nondiagnostic biopsy and the type of disease were found to have statistically significant effects on the accuracy of frozen section analysis.

Conclusion:

Frozen section analysis was diagnostic in approximately one half of open biopsy cases. Additional information in equivocal positive results suggests that frozen section analysis is helpful for intraoperative decision making (clinical utility) in 75.4% of cases.

Authors: Wood Thomas J. , Leighton Jennifer , Backstein David J. , Marsh Jacquelyn D. , Howard James L. , McCalden Richard W. , MacDonald Steven J. , Lanting Brent A.
Published: October 2018

Background:

Extensor mechanism disruption after total knee arthroplasty is a serious complication leading to notable patient morbidity. The purpose of this study is to compare the outcomes of extensor mechanism allograft with synthetic graft reconstruction.

Methods:

We retrospectively identified all patients who underwent extensor mechanism reconstruction using either allograft or synthetic graft from two high-volume academic arthroplasty institutions between 2006 and 2017. We collected extensor lag, need for ambulatory aids, and patient-reported outcome measures, as well as the incidence of postoperative complications and revision surgeries. We evaluated cost differences, considering both material cost and the need for revision surgery.

Results:

We identified 27 cases. A significantly greater postoperative extensor lag was found in the allograft group (P = 0.05). Graft failure after synthetic reconstruction was zero, with an overall revision surgery rate of 15%. Graft failure was 21%, and the revision surgery rate was 43% after allograft reconstruction. The allograft cost was significantly higher compared with the synthetic graft cost (P = 0.001). The mean total cost was 4,733.08 CAD for the synthetic group and 24,050.40 CAD for the allograft group (P = 0.17).

Discussion:

Synthetic reconstruction for extensor mechanism disruption shows benefit in postoperative extensor lag, graft failure, revision surgery, and cost when compared with allograft.

Published: October 2018

We begin this paper by introducing the Linnik distributions in both the univariate and multivariate case. An overview of simulation methods and two estimation procedures for the multivariate Linnik distribution are presented. Experiments demonstrating the accuracy of the procedures are also included. Then a novel multivariate Linnik copula is derived. The primary focus of this part of work is on simulation and estimation procedures for this copula, applying existing algorithms for simulation and estimation procedures for the multivariate Linnik distribution derived in the prior section. Several theoretical properties of the copula in relation to different dependence metrics are derived.

A note on Lamarle formula in Minkowski $3$-space
Authors: Öztürk Ufuk , İlarslan Kazım , Koç Öztürk Esra Betül , Nesovic Emilija
Published: October 2018

The Lamarle formula is known as a simple relation between the Gaussian curvature and the distribution parameter of a non-developable ruled surface. In this paper, we obtain the Lamarle formula of a non-developable ruled surface with pseudo null base curve and null director vector field in Minkowski $3$-space. We also obtain the corresponding striction line and distribution parameter of such surface. We prove that there is no Lamarle formula when the director vector field is spacelike and its derivative is null, because the ruled surface in that case is a lightlike plane. Finally, we give some examples.
Usage of the homotopy analysis method for solving fractional Volterra-Fredholm integro-differential equation of the second kind
Authors: Hamoud Ahmen , Ghadle Kirtiwant
Published: October 2018

The reliability of the homotopy analysis method (HAM) and reduction in the size of the computational work give this method a wider applicability. In this paper, HAM has been successfully applied to find the approximate solutions of Caputo fractional Volterra-Fredholm integro-differential equations. Also, the behavior of the solution can be formally determined by analytical approximation. Moreover, the study proves the existence and uniqueness results and the convergence of the solution. This paper concludes with an example to demonstrate the validity and applicability of the proposed technique.
Radiology Findings and Non-Invasive Ventilation Response
Authors: Isiklar Aysun , Serin Sibel , Esquinas Antonio
Published: October 2018

Although NIV is a simple and useful method, considerable variation in its use across countries, regions and hospitals may be noted. The patient should be evaluated according to subjective response (respiratory distress, consciousness, problems related to mask and airflow), physiological responses (respiration rate, respiratory effort, air leakage) and patient-ventilator compliance (gas exchange, pulse oximetry, arterial blood gases). Normalization in respiration rate within 1 or 2 h after initiation of treatment is one of the most important markers for recovery. The goal is to maintain respiration rate between 20 and 30 breaths/ minute. Reduction in intercostal and supraclavicular retractions, paradoxical respiration and sympathetic activity indicate success of treatment. Arterial blood gases are measured within first 2 h in order to assess pH and CO2; and as needed thereafter. In general, NIV is assessed by arterial blood gases, hemodynamic parameters and several laboratory tests. There is limited number of studies in NIV. Here, we aimed to assess radiological implications of gas distribution within lung tissue during NIV therapy.
EVALUATION OF THE POSSIBILITY OF IMPROVING THE OPERATION OF A TRANSPORT COMPANY IN THE CONTEXT OF THE VEHICLE FLEET MANAGEMENT
Authors: ORŁOWSKI Krzysztof , ORŁOWSKI Łukasz
Published: October 2018

The organization of public transport greatly contributes to the proper traffic management policy of vehicles. They are an active element cooperating with the infrastructure. However, the organization of transport is not an easy task. The constantly changing demand on lines characterized by various length and intensity of use makes it difficult to decide on the choice of vehicle. Vehicles with various technical and functional parameters along with a specific frequency of running create an offer for users which is not always adapted to their needs. All the changes affecting the functioning of the rolling stock are reflected in the costs of the communication company. Analysis of the company's operations allows to identify some areas that can be optimized. The savings concern lower fuel consumption by adjusting the capacity and type of vehicle used.

SELECTED PROBLEMS OF STOCKTAKING IN THE ARMED FORCES THEORY AND PRACTICE
Authors: NAGRABSKI Dariusz
Published: October 2018

Celem artykułu jest przedstawienie ogólnych założeń związanych z inwentaryzacją w wojskowych jednostkach budżetowych. Tematyka poruszana w artykule wpisuje się w szeroko rozumiane działania doskonalenia obszarów związanych z procesem inwentaryzacji. Dokonano analizy obowiązujących aktów prawnych oraz procesu inwentaryzacji w Siłach zbrojnych RP. Podjęte badania wykazały, że proces inwentaryzacji w wojsku należy zmodyfikować, ponieważ obecne uwarunkowani tak prawne, jak również technologiczne związane z automatyzacją procesów inwentaryzacji odbiegają od zastosowań w innych przedsiębiorstwach, np. w supermarketach. Zastosowanie automatyzacji skraca czas realizacji inwentaryzacji, wyklucza pomyłki oraz pozwala na sprawniejsze rozliczenie inwentaryzacji. Autor w podsumowaniu wskazuje kierunki zmian, które z jego doświadczenia powinny usprawnić proces inwentaryzacji w Siłach Zbrojnych RP. Zakres tematyczny, który został poruszony w niniejszym artykule jest wskazaniem kierunku do dalszych, pogłębionych badań w tym obszarze.
THEORETICAL ASPECTS OF MILITARY LOGISTICS MANAGEMENT

Published: October 2018

Zarzadzanie logistyką w wojsku jest rozumiane jako proces, ciąg posobie następującychzdarzeń. Rozpoczyna się planowaniem i poprzez organizowanie i motywowanie dochodzi do etapu kontroli. Działania te mogą być realizowane poprzez wyalienowane piony funkcjonalne takie jak np. pion materiałowy. Powoduje to jednak pewne ograniczenia i stąd też w praktyce często stosuje się podejście procesowe. Jednak i ono nie jest pozbawione wad, co skutkuje stosowaniem w realnych warunkach połączenia tych dwóch sposobów podejścia. Zwykle przynosi to pozytywne wyniki. W procesie zarządzania logistyką wojskową należy przestrzegać określonych zasad, ich stosowanie w praktyce stanowi przesłankę uzyskania pozytywnych wyników co przekłada się na skuteczną realizację zadań związanych z zaspokojeniem potrzeb logistycznych jednostek i instytucji wojskowych.

Although cone snails are among the most studied group of gastropods, new species are still regularly described. Here, we focus on Afonsoconus Tucker & Tenorio, 2013, a lineage that includes only two species from the Indo-Pacific Ocean. The analysis of molecular (partial mitochondrial cox1 gene sequences) and morphological (shell and radular tooth) characters revealed that the samples collected by dredging in deep water during a recent expedition carried out in the Mozambique Channel are different from the samples collected in the Pacific Ocean. We thus introduce here a new species, Afonsoconus crosnieri sp. nov., from the SW Indian Ocean including records from the Mozambique Channel, the Comoros and Glorieuses Islands, Madagascar, South Africa and Reunion Island.

The incipient implementation of the Industry 4.0 paradigm has led to an increase in the machines sensoring level, in the processes optimization and, thus, in the product manufacturing with a higher added value.
In this article a new aspect is described where, through the machine monitoring, the utilization of innovative elements as fixture is enabled for high quality machining processes.
These innovative elements are characterized by the great flexibility offered by them as holding component and by their low costs. However, these elements lack the enough geometrical accuracy for applications where a high shape and surface quality product are needed.
First of all, in order to have a clear vision of the singularities of each fixture type present on the state of the art, a nomenclature and a classification has been proposed based on their geometry characteristics. Hence, based on this classification, an analysis of the different fixturing solutions provided by the market has been made, enhancing the advantages of this solution against the existing ones.
With the aim of demonstrating its suitability for certain machining applications, the behavior of these sort of flexible materials has been characterized. Besides, the sensors implementation has been analyzed in order to capacitate this solution for processes where tough tolerances on parts are demanded.
Therefore, this survey demonstrates that, through the massive information gathering, not only an optimization of the existing technologies is obtained, but it is possible to develop innovative solutions that provide improved capacities to the already existing ones in the Industry.

Keywords: Flexible fixtures, fixtures classification, elastomers characterization, laser technology, accurate machining, Industry 4.0.

Laser Metal Deposition (LMD) or laser cladding is a technology capable of coating, repairing and manufacturing components by injecting molten metal powder on a substrate. Some of the advantages of this technology are: wide range of materials available in powder, reduced thermal distortion, coatings and repaired parts of high quality. However, the biggest advantage can be its relative ease of implementation in a multiprocess machine tool and subsequent automatization.
The supply of hybrid machines in the world market that implements the LMD process is increasing (IBARMIA, DMG MORI, MAZAK, OKUMA, etc...), making the production more flexible in a single machine and introducing this process in more applications and industrial sectors.
However, hybridization also presents problems that are difficult to solve. Some of the most noteworthy are those associated with the use of powdered metallic material both from the point of view of the safety and hygiene of the operators and also of the waste management and integrity of the machine itself, being its most serious effects at lower efficiency of the process.
In this article, the study of the efficiency of different LMD nozzles is addressed for the coating of a hardened steel using for it the hybrid multiprocess machine IBARMIA ZVH45 /1600 Add + process, with the aim of finding the most efficient and, therefore (the one that generates less waste) and which, in turn, offers good productivity.

Additive Manufacturing (AM) is an on growing technology in the last decade. Aeronautical industry, among others, is getting involved in this new trend for manufacturing and repairing processes. More concrete inside AM techniques, Laser Metal Deposition (LMD) is a versatile process with the capability of any repairing task, though the use of this technology is considered a multidisciplinary process that requires knowledge of several aspects: 3D digitalization, CAD/CAM programming, and the laser cladding parameters and control. Considering these many challenges, this work states a global vision through all process stages in order to implement LMD repairing technology in several industries.
Additionally, trials were performed related to different process stages with significant results serving as initial reference for turbomachinery rotary components repairs. Finally, advantages and drawbacks of LMD process, as well as industrial pioneering companies at this sector.

Profili di responsabilità infermieristica in un caso di amputazione dell’avambraccio da errata pratica infusionale in neonato prematuro
Authors: Pais dei Mori Luigi
Published: October 2018

[Nursing responsibility profiles in a case of forearm amputation by wrong infusion practice in a premature newborn]This article refers to the case of a premature newborn twin (23 weeks of gestation + 6). Of the two brothers, only one survived, in a highly compromised state of health that led to a notable and dramatic series of clinical events: infectious complications, chronic renal failure, viscera herniation, intestinal perforation, and thrombocytopenia, treated with various infusions of platelet concentrates.During an infusion of platelet concentrate, an extravasation occurred with important tissue infarction. The lesion created, secondary to ischemic necrosis, evolves into dry necrosis, from the hand to the whole forearm, and leads to the amputation of the right forearm, despite the various attempts, pharmacological and surgical, experienced to avoid the extrema ratio.The purpose of this article is to analyze what happened considering scientific clinical evidence and the profile of responsibilities related to nursing practice.
Towards an in-depth characterization of Symbiodiniaceae in tropical giant clams via multiplex metabarcoding

Published: October 2018

High-throughput sequencing is revolutionizing our ability to comprehensively characterize free-living and symbiotic Symbiodiniaceae, a diverse dinoflagellate group that plays a critical role in coral reef ecosystems. Most studies however, focus on a single marker for metabarcoding Symbiodiniaceae, potentially missing important ecological traits that a combination of markers may capture. In this proof-of-concept study, we used a small set of symbiotic giant clam (Tridacna maxima) samples obtained from nine French Polynesian locations and developed a multiplex metabarcoding method that pools and simultaneously sequences multiple Symbiodiniaceae genes for in-depth biodiversity assessments. Our results showed that the technique effectively recovered very similar proportions of sequence reads and dominant Symbiodiniaceae clades among the three multiplexed genes investigated per sample, and captured varying levels of phylogenetic resolution enabling a more comprehensive assessment of the diversity present. Multiplex metabarcoding offers significant analytical cost savings while providing exceptional phylogenetic information and sequence coverage.

Objective

Identify metabolic changes produced by dimethyl fumarate (DMF) treatment and link them to immunological effects.

Methods

We enrolled 18 MS patients and obtained blood prior to DMF and 6 months postinitiation. We also enrolled 18 healthy controls for comparison. We performed global metabolomics on plasma and used weighted correlation network analysis (WGCNA) to identify modules of correlated metabolites. We identified modules that changed with treatment, followed by targeted metabolomics to corroborate changes identified in global analyses. We correlated changes in metabolite modules and individual metabolites with changes in immunological parameters.

Results

We identified alterations in lipid metabolism after DMF treatment – increases in two modules (phospholipids, lysophospholipids and plasmalogens) and reduction in one module (saturated and poly‐unsaturated fatty acids) eigen‐metabolite values (all P < 0.05). Change in the fatty acid module was greater in participants who developed lymphopenia and was strongly associated with both reduction in absolute lymphocyte counts (r = 0.65; P = 0.005) and change in CD8+ T cell subsets. We also noted significant correlation of change in lymphocyte counts with multiple fatty acid levels (measured by targeted or untargeted methods).

Interpretation

This study demonstrates that DMF treatment alters lipid metabolism and that changes in fatty acid levels are related to DMF‐induced immunological changes.
Integral concurrent learning: Adaptive control with parameter convergence using finite excitation
Authors: Parikh Anup , Kamalapurkar Rushikesh , Dixon Warren E.
Published: October 2018

Concurrent learning (CL) is a recently developed adaptive update scheme that can be used to guarantee parameter convergence without requiring persistent excitation. However, this technique requires knowledge of state derivatives, which are usually not directly sensed and therefore must be estimated. A novel integral CL method is developed in this paper that removes the need to estimate state derivatives while maintaining parameter convergence properties. Data recorded online is exploited in the adaptive update law, and numerical integration is used to circumvent the need for state derivatives. The novel adaptive update law results in negative definite parameter error terms in the Lyapunov analysis, provided an online‐verifiable finite excitation condition is satisfied. A Monte Carlo simulation illustrates improved robustness to noise compared to the traditional derivative formulation. The result is also extended to Euler‐Lagrange systems, and simulations on a two‐link planar robot demonstrate the improved performance compared to gradient‐based adaptation laws.
Hollow‐Structured Materials for Thermal Insulation
Authors: Hu Feng , Wu Siyu , Sun Yugang
Published: October 2018

Heating and cooling represent a significant portion of overall energy consumption of our society. Due to the diffusive nature of thermal energy, thermal insulation is critical for energy management to reduce energy waste and improve energy efficiency. Thermal insulation relies on the reduction of thermal conductivity of appropriate materials that are engineerable in compositions and structures. Hollow‐structured materials (HSMs) show a great promise in thermal insulation since the existence of high‐density gaseous voids breaks the continuity of heat‐transport pathways in the HSMs to lower their thermal conductivities efficiently. Herein, a timely overview of the recent progress in developing HSMs for thermal insulation is presented, with the focus on summarizing the strategies for creating gaseous voids in solid materials and thus synthesizing various HSMs. Systematic analysis of the documented results reveals the relationship of thermal conductivities of the HSMs and the size and density of voids, i.e., reducing the void size below ≈350 nm is more favorable to decrease the thermal conductivity of the HSMs because of the possible confinement effect originated from the nanometer‐sized voids. The challenges and promises of the HSMs faced in future research are also discussed.
