Published: September 2017

Gas turbine engine dynamic stability research is an important stage of development tests aimed at ensuring its reliability. Finishing work is complicated by the fact that the engine stability depends on the interaction of many functional units, including compressor, combustor, turbine, and also on the mode of its operation and the large number of external factors. Purpose of the article is to ensure the process of testing facilities more information about the running engine gas-dynamic processes. It can speed up the identification of deficiencies in the design, elimination procedures and to reduce the finishing and final stage testing time to establish more accurately the engine stability actual border. To improve the reliability of the determination of the initial stage of occurrence of stall processes running in the engine, a new approach to the selection of monitored parameters flexural vibrations of rotor blades and the pressure pulsations is proposed.

Authors: Klemsdal Lars , Ravn Johan E. , Amble Nina , Finne Håkon
Published: September 2017

The Scandinavian industrial democracy experiments (IDEs) contained elements of organization theories, based particularly on sociotechnical systems theory (STS). In this paper, we provide an introduction to some main points of these theories and their aftermath, as a context for the six papers of the special issue on the relevance of the organization theories of the IDE for contempo- rary organizational realities.The six papers are also summarized and positioned in relation to the theoretical insights from the IDE.
Applying Principles of Sociotechnical Systems onto Working Environment Research
Authors: Thomassen Ole Jacob , Heggen Kristin , Strand Roger
Published: September 2017

The sociotechnical system approach induced a consistent system thinking into the Scandinavian working life research. Workers’ social and psychological needs and technical/systemic conditions were seen as deeply interdependent. However, a distinct field of working environment research, dominated by individual and psychological perspectives, has developed. Indeed, working life itself has undergone substantial transformations. In the shift from first to second modernity (sensu Ulrich Beck), new phenomena (risks) have emerged that challenge workers’ health. This paper discusses the potential of the sociotechnical approach to inspire the specific field of working environment research. Sociotechnical ideas are concerned about the organizational aspects of the working environment and this can challenge the dominance of individual and psychology-centred research. However, it is also necessary to renew the sociotechniocal tradition from within. We suggest a general process of a reflexive modernization of sociotechnical ideas and a stronger connection to the ‘double-hermeneutic’ as an epistemological outset.
General Theory and Local Action: Experiences from the Quality of Working Life Movement
Authors: Gustavsen Bjørn
Published: September 2017

Quality of Working Life was a researcher-driven social movement culminating in the early 1980s. Its 1981 conference had some 2000 participants from research, management, unions, and government from about 30 countries. Their unifying idea was that the kind of workplace organization demonstrated in the Industrial Democracy Experiments had an emancipatory potential for democracy, productivity, and health in the workplace and beyond. A key question remained, however: how could this transformation take place on a large scale in society? There were different attempts within the movement at combining the general frameworks required to maintain societal significance and impact on the one hand, at the same time as creating relevant knowledge for the local context. After leaving the initial ambition of a universal theory, a turn toward purely local development work was again followed by a return to the general, not as the foundation of a general theory but as elements in a social movement.

In the paper, structural changing of resin-asphaltene molecules in cracking process of oil sand bitumen are investigated. Cracking process to natural bitumen carried out in an open-to-air reactor, which extracted from oil sand by organic solvent. Reaction temperature was 450 °С and process duration was 60 min. The reactor was heated at a rate of 10 °C/min up to the desired temperature. Di-tert-butyl peroxide was used as radical formation additive. When limiting oxygen, it can be used catalyst molecule supplies as the oxidizer. The thermal destruction processes of heavy hydrocarbons with the catalyst make it possible to increase the yield of low boiling liquid products with the formation of coke and gas as by-products. High temperature leads to increase the oil content, and decrease the total resinasphaltene components in bitumen. Monte Carlo method used for construction the molecular structure of resin-asphaltene components. The calculations data determined the most stable conformation of resins and asphaltenes molecules, that the stability of the molecules affect structural characteristics such as the number of structural blocks, their size and spatial arrangement of atoms with respect to each other. Microscopic images showed that the asphaltenes have around 40‒50 nm of particle size, which large monolithic switching, weakly focused on a major surface, provided with amorphous carbon.

The results of experiments on the synthesis of micro- and nano-diamonds by an oxy-acetylene torch on the surface of the pre-deposited copper thin films are presented in this article. The influence of thickness of a buffer copper film and the ratio of the concentrations of oxygen and acetylene on the structure of the deposited samples has been studied in the course of the conducted experiments. The studies by Raman scattering and scanning electron microscopy showed that the synthesis of micro- and nano-diamonds occurs under certain experimental conditions. From the results of the analysis of the obtained samples by the methods of Raman scattering and scanning electron microscopy, it was determined that the deposition time of the copper films and consequently its thickness mainly influence on the structure formation of diamond crystals. On copper films grown for 30 min, the Raman scattering method showed a shift of the diamond peak from the standard (1332 cm‒1) to the low-frequency band (1331.3 cm‒1), which may occur after the presence of stress in the crystals. The results of the investigation showed that with increasing of synthesis time take place smoothing of the facets of crystallites (scanning electron microscopy) and decrease in intensity of the diamond peaks (Raman scattering method).

Published: September 2017

Magnesium diboride can be synthesized under argon ambient, elevated or high pressures. High-pressure syntheses are promising methods for manufacturing of the bulk MgB2 superconductor material. We have been used high pressure of Ar gas in order to investigate its effect on properties of MgB2 superconductor such as critical temperature and current density. Bulk MgB2 superconductor was synthesized from elemental Mg–B powders in thermal explosion mode of self-propagating high-temperature synthesis (SHS) under argon pressure of 25 atm. XRD pattern of the as-synthesized product indicates an almost complete conversion of the reactants to the MgB2 single phase. Most of the diffractions peaks are related to the MgB2 polycrystalline bulk material. The impurity fraction is less than 24.3% in total sample and identified as MgO and MgB4 secondary phases. The positive effect of pressure of Ar gas during synthesis of MgB2 on critical current density JC has been confirmed. The critical current density of the sample was achieved in high pressure reactor was 3.8×106 A/cm2. A superconducting volume fraction of 16% under a magnetic field of 10 Oe was obtained at 5 K, indicating that the superconductivity was bulk in nature. The succeeded level of superconductor parameters of the high-pressure synthesized MgB2 and the possibility to produce a large bulk products make this technology very promising for practical applications.

Resumo: A judicialização das questões consumeristas atinge o Supremo Tribunal Federal por via dos juizados especiais há vários anos. Recentemente uma empresa do ramo de telefonia, a Oi, destacou-se pelo volume desproporcional de processos que levou ao tribunal. Ao analisar o perfil da litigância de direito do consumidor da Oi no Supremo, identificamos que a empresa envia o dobro de processos do segundo colocado no ranking de maiores litigantes, apesar de ter taxa de sucesso menor do que 0,07%. No contexto da necessidade de adequada proteção dos direitos do consumidor, esse comportamento pode ser caracterizado como bullying processual e demanda novas atitudes por parte dos órgãos reguladores e do próprio Supremo.Palavras-chave: Direito do consumidor. Judicialização. Supremo Tribunal Federal. Abstract: The consumer rights lawsuits have reached the Brazilian Supreme Court through small claims courts for years. Recently, one phone company, Oi, stood out for the disproportional number of appeals it took to the court. We found that Oi brought double the number of appeals of the second most frequent appellant in consumer rights at the Supreme Court, even though Oi’s success rate is lower than 0,07%. In the context of appropriate consumer rights protection, this behavior can be characterized as lawsuit bullying and calls for a new attitude by the regulating agencies and the Supreme Court itself.Keywords: Consumer rights.

Published: September 2017

The present paper describes the investigation of foot-and-mouth disease (FMD) outbreak in a private pig farm at Kotty in Kollam district of Kerala during October 2013. During the clinical phase, severe vesicular lesions on snout and skin around the coronary bands were observed in pigs. A total of 48 serum samples and 12 clinical samples (ruptured snout epithelia) were collected. All serum samples were subjected to indirect 3AB nonstructural protein (NSP) ELISA and liquid phase blocking (LPB) ELISA. In 3AB NSP ELISA, all serum samples were found positive for NSP antibodies indicating infection. In LPB ELISA, 42 of 48 (87.5%) pigs were found to have protective log10 antibody titre of ³1.8 against FMD virus serotypes O, A and Asia 1. All the clinical materials were found positive for serotype O in antigen detection ELISA as well as in multiplex reverse transcription-polymerase chain reaction (mRT-PCR). In VP1 region-based phylogenetic analysis, the serotype O isolates causing the outbreak were found to conglomerate within Ind2001 lineage. Pigs infected with FMD may pose rigorous threat to other susceptible domestic livestock as they exhale enormous quantity of virus. As a consequence, they should be included under prophylactic vaccination and surveillance programmes ongoing in the country.

Lumpy skin disease (LSD) is a pox disease of cattle characterised by fever, nodules on the skin, mucous membranes and internal organs, emaciation, enlarged lymph nodes, oedema of the skin, and sometimes death. A disease form was observed in cattle in the Southeast Anatolia in 2013 and 2014 and suspected for LSD suspected by clinical examination. In this study, LSD has been defined by molecular virologic and histopathologic tests. A necropsy was undertaken and tissue samples were taken. Also, blood and tissue samples with biopsy punches were taken from animals having symptoms. Tissue and blood samples were examined molecularly and histopathologically while tissue samples were examined histopathologically. Positive amplification was detected by Polymerase Chain Reaction and confirmed by sequencing in the extracted DNA’s derived from tissues. Tissue samples were compatible with LSD histopathologically. The first official notification of LSD in Sanliurfa province of the Southeast of Turkey is determined. As a result, LSD could be treated northern territories in suitable climate conditions.

Mogućnost lažiranja rezultata na testu PIE-JRS u situaciji profesionalne selekcije
Authors: Okanović Predrag , Okanović Dragana
Published: September 2017

Istraživanje je sprovedeno sa ciljem da se odgovori na dva pitanja: da li je moguće namerno lažiranje skorova na testu Profil indeks emocija u smislu boljeg predstavljanja, i da li kandidati za posao zaista koriste tu mogućnost u situaciji profesionalne selekcije? Ukupan uzorak (N=539) je činilo dve grupe ispitanika: (1) ispitanici koji su popunjavali test PIE-JRS na dva načina (prvo iskreno, a potom sa instrukcijom da se predstave na što bolji način) i (2) realni kandidati za posao u procesu profesionalne selekcije. Sprovedene su dve odvojene analize kako bi se dao odgovor na dva istraživačka pitanja. Na osnovu prve sprovedene analize zabeležena je delimična podložnost lažiranju ovog testa - tri skale su demonstrirale otpornost na lažiranje, dok pet skala nije. Prilikom instruisanog lažiranja, ispitanici se najviše trude da se predstave kao poslušni i nekonfliktni kandidati (podizanjem skora na skali Inkorporacije i snižavanjem Agresije i Odbacivanja). Ovakav obrazac u odgovaranju je naročito uočljiv kod žena i pripadnika humanističkih struka. Na osnovu druge etape možemo zaključiti da kandidati na procesu selekcije zaista koriste mogućnost lažiranja odgovora - kada se porede ispitanici iz fiktivne i realne profesionalne selekcije, na pet skala testa PIE-JRS nema razlika, a na preostale tri realni kandidati postižu poželjnije rezultate.

Cilj rada bio je provjeriti odnos perfekcionizma, samoefikasnosti i ispitne anksioznosti kod studenata, odnosno ispitati koje dimenzije perfekcionizma predviđaju ispitnu anksioznost, te posreduje li samoefikasnost u njihovom odnosu. U istraživanju je sudjelovalo 214 studenata, a korišteni su Frostova multidimenzionalna skala perfekcionizma, Skala opće samoefikasnosti i Upitnik ispitne anksioznosti. Rezultati su pokazali da je ispitna anksioznost pozitivno povezana s neadaptivnim dimenzijama perfekcionizma – neurotskim perfekcionizmom i roditeljskim pritiskom, te negativnosa samoefikasnošću, dok nije bilapovezana s adaptivnim dimenzijama perfekcionizma – osobnim standardima i organiziranošću. Nadalje, pokazalo se da neurotski perfekcionizam i roditeljski pritisak predviđaju ispitnu anksioznost. Konačno, rezultati sugeriraju da je odnos neurotskog perfekcionizma i osobnih standarda posredovan samoefikasnošću.

Lembrar e esquecer, mostrar e ocultar são verbos de uma dinâmica fotográfica e histórica que tende a encarar o tempo como descontínuo. Com base no pensamento benjaminiano acerca da relação entre imagem e história, é feita uma leitura do trabalho do artista francês Christian Boltanski, que se destaca por trazer à tona a idéia de “monumento” desligada de nomes de grande relevância social. As “pequenas memórias” de que o artista trata em suas imagens se dirigem a dos inúmeros anônimos que, como rastros frágeis, permanecem ocultos ante à força monumental do historicismo.

In this paper, we introduced a fiber to the home network access based on gigabit passive optical network (FTTH-GPON) in Jakarta Garden City Area. We proposed a design using google earth and optisystem. The proposed system used 2.4 Gbps bitrate for downstream and 1.2 Gbps bitrate for upstream. We looked for suitability of the proposed design with the ITU-T FTTH-GPON standard. We used the link power budget and the risetime budget method to design the access network. Based on calculation, we got the value of link power budget equal to 22 dB, the power margin equal to 3 dB and the risetime budget equal to 0.27 ns for downstream and 0.25 ns for upstream. To analyze the system performance, we used eye-diagram method to get jitter, distortion, signal to noise ratio (SNR), Q-factor, and BER. Based on the experimental result with power 5dBm and wavelenght 1490nm, we got the jitter 16.7 ps, the distortion 1.07µ a.u., the SNR 6.87, the Q-factor 21.249 and the BER 1.9 ×10-99. The result reveal that in all cases, the Jakarta Garden City FTTH-GPON design met with ITU-T standard

The success of a nanosatellite mission is depend on the reliability of the Electrical Power System (EPS) to ensure the subsystems on the nanosatellite working properly. Therefore, an effective power distribution control is required. This research will explain how to distribute electrical power effectively to the subsystems according to the condition of the nanosatellite (sunlight or eclipse). To illustrate this, a simulation and analysis of the EPS power management module design consisting the LT3757 boost converter and LT3652 battery charger were performed. From the simulation results, it will be seen that when the nanosatellite is exposed to the sun, the system will distribute the power to the load using the input power from the panel surya that has passed the boost converter component (12 Volt), while charging the battery until it’s fully charged (7,4 Volt). But during the eclipse phase the system will supply the load with the power generated by the battery (7,4 Volt)

Los hogares rurales diversifican sus ingresos como estrategia para minimizar los riesgos, reducir la variabilidad y asegurar un nivel mínimo de ingreso. Con información panel de la Encuesta Nacional a Hogares Rurales de México, el presente estudio examina, bajo una perspectiva de género, los factores que determinan la participación en el sector no agropecuario. Los resultados señalan que en las ocupaciones asalariadas no agropecuarias, los hombres participan con menores niveles de escolaridad y la condición de indígena limita la incorporación de ambos géneros. En actividades no agropecuarias por cuenta propia son esenciales la riqueza acumulada del hogar y los servicios financieros, de comunicación y transporte.
Venezuela's melting pot: 1500-1800
Authors: Livi Bacci Massimo
Published: September 2017

Not much is known about the demography of the native population of Venezuela in Colonial times. Until mid-17th century, some factual information may be gained from the narratives of the first conquistadores, missionaries and colonists, as well as of authors writing in later times of the Colony, but with access to original sources. After mid-17th century, some quantitative information of demographic relevance was collected by the Jesuit, Capuchin and Franciscan missionaries and, in the last decades of the 18th century, by the colonial administration and the religious authorities. The native population declined, from between 200,000 and 500,000 inhabitants at contact (guesstimates of modern authors) to perhaps 120,000 in 1800, according to Humboldt’s estimate. It is possible that the initial decline became steeper after the first smallpox pandemic of the 1580s and continued, at a slower pace, until the Independence. As in other regions of South America, marriage was early and almost universal, and the high ratio of births to deaths seems to indicate a high potential for growth, interrupted by frequent mortality crisis.A competing cause of the decline of the natives was the process of mestizaje that intensified with the increase of the population of European and African origin.
The Natural History of the Development of Trevor Disease of the Hip and Subsequent Arthroplasty
Authors: Shahcheraghi Gholam Hossain , Javid Mahzad
Published: September 2017

Case:

Trevor disease (dysplasia epiphysealis hemimelica [DEH]) is a rare, intra-articular anomaly of cartilaginous overgrowth of the epiphysis. The usual presentation is on 1 side of the body and on 1 side of the epiphysis. The natural history of this disease is not clear because the lesions often are treated during childhood. Additionally, hip involvement is relatively uncommon; to our knowledge, total hip arthroplasty in a patient with DEH has not been reported previously. Our patient presented with previously untreated DEH of the hip joint, which had developed into a very unusual shape. He was treated with a total hip arthroplasty and had satisfactory functioning 2.5 years postsurgery.

Conclusion:

Untreated DEH of the hip can lead to a very misshapen hip with a deformed femoral head and loss of the shape of the acetabulum, as well as stiffness due to an unusual shape and osteoarthritic changes. A total hip arthroplasty can give satisfactory functional results.

Case:

A patient with rheumatoid arthritis (RA) who was being treated with methotrexate (MTX) therapy presented with severe swelling of the left elbow. Magnetic resonance imaging showed a tumor-like lesion around the elbow joint. Fluorodeoxyglucose positron emission tomography indicated multiple lesions in the lung and the lymph nodes. An open biopsy of a cervical lymph node was performed, and MTX-related lymphoproliferative disorder (MTX-LPD) was diagnosed. After cessation of the MTX therapy, the elbow swelling regressed, and the patient was in remission of MTX-LPD.

Conclusion:

MTX-LPD should be considered in the differential diagnosis when a patient with RA develops severe joint swelling while on MTX therapy.

Young musicians often report problems with their upper limbs and spine due to their specific and asymmetric positions and actions while playing, which may contribute to overloading these structures. Diagnosing any disorders to the upper limbs or spine early may help to minimize the
risk of developing any serious instrument-related health problems in the future. The aim of this study was to assess the anteroposterior (AP) spinal curvatures in children learning to play the violin. Previous studies have shown anthropomorphic differences in young adult musicians, and our
study examined if these differences appeared early or late in the musician’s career. METHODS: Body posture of 101 children, aged 7–12 yrs (mean 11.09±1.48), was assessed. The study population consisted of 49 child violinists and a control group of 52 children who did not
play any musical instrument. There were 81.19% girls and 18.81% boys. Body posture was analyzed using the MORA 4G. RESULTS: The violinist group showed significant differences in the thoracolumbar region angle (p=0.004) compared to the non-musical children. The remaining parameters did not
reveal significant differences between groups. The parameter characterizing the location of kyphosis peak calculated from the spinous process of the C7 vertebra was significantly higher in the study population. CONCLUSIONS: Changes in body posture in children who play the violin appear early
in their training. Body postures when playing the violin lead to some changes in parameters characterizing AP spinal curvatures in the sagittal plane.

Musculoskeletal Problems in Performers
Authors: Fielding David
Published: September 2017

The interesting article on musculoskeletal problems in pianists by Moñino et al. in the June issue raises some of the “physician’s dilemmas” in their approach to performing arts medicine, in all areas of diagnosis, prevention, and performer education. The authors
have been able to transfer the disorders observed in their pianists from the largely unhelpful “PRMD” label to more “objective” categories by giving them an ICD-10 classification. This helps to group them more rationally, but the categories identified for the greater
number of problems remain, as might be expected, symptomatic (e.g., M54.2 cervicalgia) and not specific “disease” categories. Over half of the pianists’ problems fell within ICD-10 categories which are non-specific.
The Sickness of Stigmas
Authors: Ackermann Bronwen J
Published: September 2017

In modern medicine, approaches to healthcare no longer only encompass injury management, but increasingly focus on understanding the performance demands and health risk exposures faced by performing artists. Quantitative and qualitative scientific and health analyses by performing artists,
clinicians, educators, and researchers are increasingly helping us to develop effective, targeted, and relevant health promotion and performance optimisation strategies worldwide. While such research increasingly identifies improved methods of preventing and managing potential psychological,
audiological, or physical challenges faced by performing artists, we still need to work hard to address very important barriers to implementing appropriate health approaches. One of the challenges to better health management in performing arts populations relates to stigmatization.

ESCENAS DE UNA VIDA DE PROVINCIAS DE J. M. COETZEE: UNA MIRADA A LA NOVELA AUTOBIOGRÁFICA DESDE LA ANALÍTICA EXISTENCIAL DE MARTIN HEIDEGGER
Authors: Herrera Rodríguez Camilo
Published: September 2017

Este artículo tiene la intención de revisar la obra autobiográfica Escenas de una vida de provincias, escrita por J. M. Coetzee, a la luz de la teoría de la autobiografía y de la analítica existencial propuesta por Martin Heidegger, con el fin de determinar las relaciones existentes entre ambas en Ser y tiempo. El análisis del texto considerará aspectos teóricos: el ser, el mundo y la muerte, como elementos rastreables en “Infancia”, “Juventud” y “Verano”, títulos que componen la publicación Escenas de una vida de provincias; y los conceptos heideggerianos en Ser y tiempo.
