Mycoplasma spp. mastitis — approach to diagnosis
Authors: Manning Al
Published: July 2020

Mycoplasma spp. mastitis outbreaks are rare, but when they occur they tend to be characterised by recurrent mastitis that is non-responsive to treatment, and a high rate of subclinical infections. These symptoms are often seen in conjunction with chronic calf pneumonia, and polyarthritis. General screening of individual cows or bulk tanks for Mycoplasma spp. is likely to result in more false positives than true positives, whichever test is chosen. Instead of using screening tests, veterinary surgeons should use targeted investigations on farms that meet the criteria of a suspected Mycoplasma spp. outbreak. For investigating individual animals, the most accurate test is likely to be bacteriological culture using selective growth media. For investigating bulk tanks, Mycoplasma bov is antibody testing is most sensitive but should be complemented with polymerase chain reaction (PCR) or culture to detect other species. Diagnostic sensitivity is increased by repeating or using a combination of tests, however this will increase the risk of false positives.
Os Estados Unidos e a Inglaterra vistos pelo cinema soviético do stalinismo tardio
Authors: Franciscon Moisés Wagner
Published: July 2020

O sistema soviético sofreu uma série de reformas no pós-guerra que, se não deram origem ao esperado regime mais liberal, amenizou algumas de suas características (como a eliminação física) e acentuou outras (como a eficácia da censura). Externamente, a Primeira Guerra Fria exigia uma luta cultural travada em iguais condições com aquela criada pelos impérios rivais anglo-americanos. O cinema assumiria importantes funções de contrapropaganda interna e externa. Os vilões estrangeiros genéricos dos anos 1930 dão lugar a personagens claramente caracterizados ou anunciados como britânicos e estadunidenses. A sócio-história cinematográfica de Marc Ferro permite demonstrar que, apesar da existência residual da crítica marxista-leninista, impõe-se uma imagem invertida da própria propaganda antissoviética das duas democracias liberais. Assim, para o cinema soviético do período (1945-53), os bêbados, autoritários, improdutivos, caóticos economicamente, presas e agentes da censura são os anglo-americanos.

Analysis of Sinusoidal Pulse Width Modulation Parameter Settings in High Precission Closed Loop Full Bridge Bipolar Inverters for High Voltage High Frequency Generator
Authors: Syakur Abdul , Wibisono Arifin
Published: July 2020

The application of high voltage becomes more important and wider. High voltage is needed in the process of reducing air contaminants, waste treatment, sanitation, disinfecting microorganisms, testing for insulating high voltage equipment, and transmitting electrical energy. The problem of high voltage AC generation system is still in a large scale, static, not portable, and very expensive. This paper presents an analytical design of a high-voltage AC high-frequency based on power electronic. It is portable, less expensive, and eaasier to control the amplitudo and frequency. The application of the Full Bridge Bipolar Inverter topology with the Sinusoidal Pulse Width Modulation switching method provides variable sinusoidal AC voltage outputs (Vo) on its amplitude and frequency. The Tesla Coil Transformer amplifies the amplitude in accordance with the classification of the high voltage AC in the order of Kilo Volt. The Closed Loop control system in the Bipolar Inverter Full Bridge topology provides high accuracy results between the given setting values and the actual amplitude output and the expected high-frequency AC voltage. Analysis of the SPWM switching pattern parameter settings shows stability for several loading variations

Didaktische Effekte des Umgangs mit Tieren in ausgewählten Robinsonaden
Authors: Doms Misia Sophia
Published: July 2020

Der grundlegende Sammelband Robinsons Tiere (hrsg. von Roland Borgards, Marc Klesse und Alexander Kling) hat jüngst die Mensch-Tier-Interaktion in der Literaturgattung der Robinsonade näher beleuchtet. Der Fokus des Bandes liegt dabei auf der ethischen und politischen Dimension des speziesübergreifenden Umgangs miteinander. Welche didaktischen Effekte die Interaktion mit lebenden oder toten Tieren für die Protagonisten der untersuchten Robinsonaden hat, gerät dagegen kaum in den Blick. Dieser Frage widmet sich der vorliegende Aufsatz, der sich mit Daniel Defoes Prototyp und den Robinsonaden von Joachim Heinrich Campe, von Johann David und Johann Rudolf Wyss, von Marlen Haushofer sowie Yann Martel befasst.
Impact Assessment of Farm Tractor Engine Fuel Injector Damage on Engine Oil Properties
Authors: Gołębiowski Wojciech , Zając Grzegorz
Published: July 2020

It is justified that the problems related to changes in physico-chemical properties, concentration of trace elements in lubricat-ing oil and the impact of these changes and their dynamics on vehicle structural elements should be considered in detail. It is important that empirical data, theoretical relationships and test results should be taken into account. The paper presents re-search results of the selected physico-chemical parameters and the content of metals in samples of the used engine oil. The samples were collected both after the fuel system failure and during the operation of the farm tractor according to the date of changing engine oil assumed by the producer. An instrumental chemical analysis method HDXRF was used to determine chang-es of the content of trace elements Fe, Sn, Cu, Pb, P, Zn, Ca in engine oil. Additionally, changes in physico-chemical properties were determined with the use of FT-IR spectrometry. Courses of these changes were analysed on account of their impact on the utility properties of the engine oil.
Aufschlussreich, wenn gut gebaut: Die Zuverlässigkeit des unzuverlässigen Erzählens bei Perutz, Lernet-Holenia und Hesse
Authors: Waszak Tomasz
Published: July 2020

The paper investigates a specific period in the history of unreliable narration, or, more precisely, of its mimetic variation that is based on ontological misinformation. Using the example of three German-language literary texts of classical modernism, the functions and conditions of success of the literary device in question are analyzed. A comparison of the interpretation of reality offered by the texts allows for the construction of a cultural-historical tendency of development; however, the examined texts seem to position themselves chronologically in a retrograde manner to that tendency. Reasons for this paradox are explained in regards to the – particularly political – functionalization of the myth in classical modernism. The analysis of the requirements for a successful deception of the recipient is based on three narratological criteria. An examination of how these criteria are (or are not) met in the chosen texts reveals a need for more terminological refinement and additionally inspires a fundamental reinterpretation of one of the case examples.
On the Limits of Macroprudential Policy
Authors: Kolasa Marcin
Published: July 2020

This paper studies how macroprudential policy tools applied to the housing market can complement the interest rate-based monetary policy in achieving one additional stabilization objective, defined as keeping either economic activity or credit at some exogenous (and possibly time-varying) levels. We show analytically in a canonical New Keynesian model with housing and collateral constraints that using the loan-to-value (LTV) ratio, tax on credit or tax on property as additional policy instruments does not resolve the inflation-output volatility tradeoff. Perfect targeting of inflation and credit with monetary and macroprudential policy is possible only if the role of housing debt in the economy is sufficiently small. The identified limits to the considered policies are related to their predominantly intertemporal impact on decisions made by financially constrained agents, making them poor complements to monetary policy, which also operates at an intertemporal margin. These limits can be overcome if macroprudential policy is instead designed such that it sufficiently redistributes income between savers and borrowers.
Updating Awareness and Information Aggregation
Authors: Galanis Spyros , Kotronis Stelios
Published: July 2020

The ability of markets to aggregate information through prices is examined in a dynamic environment with unawareness. We find that if all traders are able to minimally update their awareness when they observe a price that is counterfactual to their private information, they will eventually reach an agreement, thus generalising the result of Geanakoplos and Polemarchakis (1982). Moreover, if the traded security is separable, then agreement is on the correct price and there is information aggregation, thus generalizing the result of Ostrovsky (2012) for non-strategic traders. We find that a trader increases her awareness if and only if she is able to become aware of something that other traders are already aware of and, under a mild condition, never becomes aware of anything more. In other words, agreement is more the result of understanding each other, rather than being unboundedly sophisticated.
Meereswind oder regionale Sonne?
Authors: Hutter Ralf
Published: July 2020

Im Streit um große Stromtrassen von Nord- nach Süddeutschland, der auch die Energiewende-Bewegung spaltet, geht es letztendlich um die Grundsatzfrage, wie das weitere Voranschreiten der Energiewende vonstattengehen soll: Soll der Fokus auf großen Windparks im Meer liegen oder auf möglichst regionaler Stromerzeugung? Dieser Artikel beschreibt, dass der Stromtrassenbau auf absehbare Zeit dem deutschen Modell des Strommarkts und dem europäischen Energiehandel geschuldet ist und dass die Kritik an den Trassen deshalb gerechtfertigt ist. Die Hauptargumente der Gegenseite, die die Trassen als nötig für die europäische Energiewende ansieht, werden ebenfalls erwähnt. Nach Hinweisen auf die Diskussion über regionale Strommärkte und die aktuelle Rückkehr der Solarenergie wird als weiterer Aspekt das Gerechtigkeitsproblem dargestellt, dass ländliche Regionen mit wenig Strombedarf unter dem immer größeren Stromhunger der Metropolen leiden, weil sie den Raum für Strominfrastruktur bereitstellen müssen.
Die Angst vor der Katastrophe macht noch keine bessere Zukunft
Authors: Maier Jürgen
Published: July 2020

Wie sehr taugen Katastrophenszenarien, um politisch wirksame Mehrheiten für eine andere Politik zu gewinnen? In Zeiten wachsender sozialer Polarisierung treiben große Teile der Bevölkerung andere Fragen um als Klimaschutz. Mit einem „Green New Deal“ Neoliberalismus und Klimakrise gleichzeitig anzugehen, ist daher ein zukunftsfähiger Weg. Damit können auseinanderdriftende Gesellschaften wieder zusammengebracht werden, sowohl politisch als auch ökonomisch. Die Kosten für den Klimaschutz dürfen nicht „gleichmäßig auf alle“ verteilt werden, sondern müssen zu einer Umverteilung von oben nach unten beitragen. Der Green Deal der EU-Kommission ist der falsche Weg, weil er Klimaschutz als renditebringendes Anlageobjekt für Investoren vorsieht, mit dem es eine „just transition“ für Anleger gibt, aber nicht für arbeitende Menschen.
Systematische Verankerung von Klimaschutz-Themen in lokalen Bildungslandschaften?
Authors: Ahlke Josef , Paust-Lassen Pia
Published: July 2020

In vielen zivilgesellschaftlichen Initiativen und Projekten werden Ideen und innovative praktische Maßnahmen zum Klimaschutz und zur nachhaltigen Entwicklung seit einigen Jahren umgesetzt. Spätestens seit der UN-Konferenz in Rio 1992 mit den Beschlüssen zur Agenda 21 (UNCED), der Weltkonferenz 2002 in Johannesburg (WSSD) und der UN-Konferenz 2012 in Rio wird der Aspekt der Bildung für nachhaltige Entwicklung (BNE) ausdrücklich hervorgehoben. BNE ist ebenso Bestandteil des Pariser Abkommens zum Klimaschutz (im Artikel 12). – Bildung für nachhaltige Entwicklung ist dringender denn je. Der Klimawandel als globale Herausforderung verlangt nach sofortiger Veränderung unserer Lebensstile und einer Transformation unseres Denkens und Handelns. Bildungssysteme müssen auf diese Herausforderungen reagieren und relevante Handlungsfelder und Inhalte definieren, die Selbstwirksamkeit der Lernenden durch pädagogische Methoden erreichen und in ihren Bildungsinstitutionen die Prinzipien der Nachhaltigkeit auch in die Management-Strukturen integrieren. Dennoch kann beobachtet werden, dass bislang eine systematische Verankerung von BNE und Klimaschutzbildung nur sporadisch zu finden sind. Für eine wirksame Bildung zur Umsetzung der Nachhaltigkeitsziele (SDG, Agenda 2030; Education for Sustainable Development/ESD) ist eine Weiterentwicklung der vielen guten Projektansätze zu transformativer Bildung notwendig. Dies ist nur über eine kontinuierliche Verankerung mit finanzieller Grundausstattung für die lokalen und kommunalen Bildungslandschaften erreichbar.
A simple quad-band printed diversity antenna with high isolation without extra structure
Authors: Imani Azadeh , Bayati Mohammad Sajjad
Published: July 2020

In this paper a Quad-band diversity antenna with a small size of 48 × 28 × 0.8 mm3 printed on FR4 substrate is presented that consists of two same pentagonal-shaped patch elements. Four arc-shaped slots in the radiating elements are introduced to obtain the quad-band operation with good return loss. The antenna is designed for covering 5.91 GHz in IEEE 802.11 b/g/n standards, 7.40 GHz in C-Band, 9.18 and 10.72 GHz in X-Band. To achieve the lowest coupling between two elements, three structures for embedding elements are investigated. The prototype is fabricated, and measured results are in good agreement with simulated results. The final antenna accomplishes a weak mutual coupling below −29.2 dB in the all operational bands. Radiation characteristics, radiation efficiency and diversity performance such as diversity gain and envelope correlation coefficient of the final structure, are presented.
Developing waist circumference, waist-to-height ratio percentile curves for Pakistani children and adolescents aged 2–18 years using Lambda-Mu-Sigma (LMS) method
Authors: Asif Muhammad , Aslam Muhammad , Altaf Saima , Mustafa Sajid
Published: July 2020

Objectives

Children from different countries and with different ethnic backgrounds have a distinct pattern of central fat deposition. Therefore, it is essential to develop population-specific percentiles of waist circumference (WC), waist-to-height ratio (WHtR) and waist-to-height ratio exponent (WHtR (exp)) for the evaluation of central obesity. The objective of this study was to develop age-and-gender-specific smoothed WC and WHtR percentile curves for the Pakistani children and adolescents aged 2–18 years.

Methods

A cross-sectional data-set from a multi-ethnic anthropometric survey was considered. A sample of 10,668 healthy subjects (boys = 51.92%; and girls = 48.08%), aged 2–18 years was studied. Height (cm) and WC (cm) of each subject was measured under standard procedure and WHtR & WHtR (exp) were calculated. Age-and-gender-specific smoothed curves were obtained using the lambda-mu-sigma (LMS) method and compared with percentile curves obtained from different countries.

Results

Except few early ages, the WC values increased with age in both sexes. Both boys and girls had approximately similar WC during 6–11 years of age and after age of 11, the boys had larger WC than the girls had. For WHtR, the centile curves showed a continuous decrease by 16 years of age and then increased gradually. WHtR of the girls in various ages were having similar or higher than those of the boys. In comparison of WC 50th and 90th percentiles with other countries, it was found that except few ages, the Pakistani children had larger WC than the other reference populations and the results of WHtR were also comparable to the other nations.

Conclusions

We present new reference data of WC, WHtR and WHtR (exp) using a representative sample of the Pakistani children aged 2–18 years. These reference values can be used provisionally for early detection of central obesity and its associated risks in the Pakistani children.
Saudi children with celiac disease: are they at risk of developing type-1 diabetes mellitus?
Authors: Saadah Omar I. , ALsaiari Ameera S. , Al-Mughales Jamil A.
Published: July 2020

Objectives

Patients with type-1 diabetes mellitus (T1DM) and celiac disease (CeD) share the same genetic susceptibility alleles. The diabetes-associated autoantibodies (DAA) may be detected in CeD patients. The aim of this study is to describe the prevalence of DAA in children with CeD.

Methods

This is a cross-sectional study of children with CeD. The CeD patients were divided into two groups; group 1 (n=23) included patients with isolated CeD and group 2 included patients with combined T1DM and CeD. The study was conducted at King Abdulaziz University Hospital (KAUH) in 2012–2014. DAA, including glutamic acid decarboxylase antibodies (GADA) and protein tyrosine phosphatase-2 antibodies (IA-2), were measured by enzyme-linked immunosorbent assay (ELISA) in both groups. Clinical, demographic, and laboratory data were collected from the patients’ medical charts.

Results

DAA were determined in 23 patients in group-1 and 18 patients in group-2. Group-1 comprised 43.5% males and 56.5% females; the mean age was 15 ± 3.7 years (with a range of 5–18 years). The prevalence of GADA and IA-2 was 69.6 and 4%, respectively. Group-2 comprised 55.6% males and 44.4% females; the mean age was 15.1 ± 2.8 years (with a range of 7–18 years). The prevalence of GADA and IA-2 was 66.7 and 22.2%, respectively. No significant differences were found between both groups in the prevalence of GADA (p=1.0) or IA-2 (p=0.15).

Conclusions

Saudi children with CeD have higher prevalence of GADA than reported in a number of other Western studies. Long-term follow-up data is required before recommending routine screening for DAA.
Die ‚patria potestas‘ in Boccaccios ‚Decameron‘
Authors: Doering Pia Claudia
Published: July 2020

The power of fathers over their children – especially over their daughters – is a central theme of Boccaccio’s ‘Decameron’. Novella V,7 situates the ‘patria potestas’ in a tension-filled position between honour and law, vigilante justice and public prosecution. The legitimation of cruelty and violence by invoking the ‘patria potestas’ is questioned through the confrontation with poetic justice.
„Indo-European in Basis and Origin“. Das altirische Recht zwischen insularem Archaismus und europäischer Verflechtung
Authors: Bubert Marcel
Published: July 2020

Research on Old Irish law was from the very beginning related to specific epistemological and political contexts in which Celtic and Indo-European Studies emerged as scientific disciplines at the end of the 19th century. The premise of historical linguistics that the Indo-European languages derived from a common ‘origin’ had far reaching implications for studies on medieval Celtic law tracts. Since linguists had discovered significant parallels between Old Irish and Sanskrit, the legal traditions of Ireland and India were believed to preserve archaic Indo-European continuities as well. Against this background, and in a particular political context, Irish scholars of the 20th century argued for the autonomy and isolation of Old Irish law which was supposed to be unaffected by the Latin and Christian literature of continental Europe. However, later researches departed radically from this national perspective and emphasized the impact of Canon law, hagiography and the Bible on Irish written culture. This article takes up a different perspective by focusing on the persistence of a legal imagery that was by no means essentially Indo-European but still provided conceptual tools for the interpretation and ‘translation’ of texts, as they occur in vernacular adaptations of Latin literature.
Marginalia in Medieval Western Scandinavian Law Manuscripts
Authors: Drechsler Stefan
Published: July 2020

In the present chapter, the design of select margins of late medieval Old Norse manuscripts containing the Icelandic ‘Jónsbók’, ‘Kristinréttr Árna biskups’ and Norwegian ‘Landslǫg’ law codes is addressed. In particular, it discusses the size and fillings of margins in these codices and the relation to their modes of use by original clients and later owners. Although it is well-known that Scandinavian law manuscripts contain a large number of notes written by both original and later users, the particular use of marginal spaces by original scribes and illuminators for glosses and other annotations and illuminations has scarcely been investigated to date. In my contribution, two distinctive features will be addressed: (1.) The different use of margins by Norwegian and Icelandic readers of the manuscripts, and (2.) the use of margins by illuminators surrounding the column(s) and incorporated initials.
Befriending Job: Theodicy Amid the Ashes
Authors: Scott Mark Stephen Murray
Published: July 2020

What role should theodicy play in the face of loss and acute suffering? Should it keep its distance and remain respectfully silent or should it step forward to illuminate the opaque reality of evil, especially untimely death? In my article, I explore the fraught relationship between the personal experience of loss and its theological interpretation through an analysis of three related bereavement autobiographies: C. S. Lewis’s A Grief Observed, Nicholas Wolterstorff’s Lament for a Son, and William Abraham’s Among the Ashes. Invoking Job’s “friends” as a theoretical framework, I analyze each author’s attempt to reconcile the lived experience of suffering with the theoretical task of theodicy: to explain suffering. I conclude with my own constructive proposal on the place of theodicy in the realm of human anguish.
Polylactide-based stent coatings: biodegradable polymeric coatings capable of maintaining sustained release of the thrombolytic enzyme streptokinase

The paper describes synthesis and testing of novel biodegradable polylactide-based polymer membranes with desired mechanical properties, which are capable of sustained and directed release of biomacromolecules with high molecular weight (in particular, streptokinase; m.w. 47 kDa). Streptokinase is a pharmaceutical agent, possessing a pronounced thrombolytic activity. The membranes synthesized had a percentage elongation of 2–11% and tensile strength of 25–85 MPa. They were biodegradable – yet being stored in aqueous media in the absence of biological objects, would be dissolved by no more than 10% in 6 months. The synthesized membranes were capable of controlled release of streptokinase into the intercellular space, with the enzyme retaining more than 90% of its initial activity. The rate of streptokinase release from the membranes varied from 0.01 to 0.04 mg/day per cm2 of membrane surface. The membrane samples tested in the work did not have any short-term toxic effects on the cells growing de novo on the membrane surface. The mitotic index of those cells was approximately 1.5%, and the number of non-viable cells on the surface of the polymer films did not exceed 3–4% of their total amount. The implantation of the synthesized polymers – as both individual films and coatings of nitinol stents – was not accompanied by any postoperative complications. The subsequent histological examination revealed no abnormalities. Two months after the implantation of polymer films, only traces of polylactide were found in the implant-surrounding tissues. The implantation of stents coated with streptokinase-containing polymers resulted in the formation of a mature and thick connective-tissue capsules. Thus, the polylactide membranes synthesized and tested in this work are biodegradable, possess the necessary mechanical properties and are capable of sustained and directed release of streptokinase macromolecules.
Faraday and Kerr Effects in Right and Left-Handed Films and Layered Materials
Authors: Lofy Josh , Gasparian Vladimir , Gevorkian Zhyrair , Jódar Esther
Published: July 2020

In the present work, we study the rotations of the polarization of light propagating in right and left-handed films and layered structures. Through the use of complex values representing the rotations we analyze the transmission (Faraday effect) and reflections (Kerr effect) of light. It is shown that the real and imaginary parts of the complex angle of Faraday and Kerr rotations are odd and even functions for the refractive index n, respectively. In the thin film case with left-handed materials there are large resonant enhancements of the reflected Kerr angle that could be obtained experimentally. In the magnetic clock approach, used in the tunneling time problem, two characteristic time components are related to the real and imaginary portions of the complex Faraday rotation angle . The complex angle at the different propagation regimes through a finite stack of alternating right and left-handed materials is analyzed in detail. We found that, in spite of the fact that Re(θ) in the forbidden gap is almost zero, the Im(θ) changes drastically in both value and sign.
Food chemoprevention and air pollution: the health comes with eating
Authors: Visalli Giuseppa , Facciolà Alessio , Laganà Pasqualina , Di Pietro Angela
Published: July 2020

Ambient air pollution is known to be an important causative agent of many non-communicable diseases, mainly due to fine particulate matter (PM2.5). According to Global Burden Disease study in 2015, the estimated premature deaths caused by PM2.5 were 4.2 million. Besides deaths, airborne pollution’s effect on human health also has dramatic economic and social costs, contributing greatly to disability-adjusted life-year (DALY). To reduce the health impact is necessary a double approach, which includes the improvement of air quality and food chemoprevention, aimed at enhancing the homeostatic abilities of exposed subjects. The scavenging, antioxidant, and anti-inflammatory properties of nutraceuticals effectively counteract the pathogenic mechanisms common in almost all non-communicable diseases associated with air pollutants. Moreover, several bioactive compounds of food modulate, by epigenetic mechanisms, the metabolism of xenobiotics, favouring conjugation reactions and promoting excretion. This narrative review summarize the numerous pieces of evidence collected in the last decades by observational and experimental studies which underline the chemopreventive role of flavonoids, contained in several fruits and consumer beverages (wine, tea, etc.), and isothiocyanate sulforaphane, contained in the cruciferous vegetables belonging to the genus Brassica. These bioactive compounds, enhancing the individual homeostatic abilities, reduce the harmful effects of airborne pollution.
How to End theOdyssey
Authors: Bakker Egbert J.
Published: July 2020

This contribution discusses the plot of the Odyssey as a field of opposing forces shaping the ending of the poem: (i) the generic tension between folktale and epic; (ii) the fundamental ambiguity of the poem’s climactic event, the killing of the Suitors (justice or revenge?); and (iii) the antagonism between Zeus and Poseidon. On this basis two competing scenarios for the ending of the poem are proposed: amnesia and departure, the former viewing the theme of revenge on the human plane, the latter on the divine.
Narratives ofamor,armaandarmenta in Ovid’sMetamorphoses
Authors: Paschalis Michael
Published: July 2020

Ovid frequently organizes individual “narratives” on the basis of semantic relations (including etymology) that link together basic concepts and themes. This web of semantic relations creates a second level of text or subtext that deepens our understanding of the composition of the poem and adds meaning(s) to each particular narrative. One such subtext concerns the semantics of erotic violence or of “love” (amor) and “arms” (arma), the study of which can enrich our understanding of Ovid’s narrative skills. The pair amor and arma is sometimes expanded to include armenta in the sense of “cattle,” “oxen,” or any animal less commonly or uniquely assigned to this species. The addition of armenta to the semantic cluster is due to the fact that they are often included in Ovid’s mythological narratives, either as real animals or as transformed human beings or as disguised divinities.

Published: July 2020

Using freshly synthesized Fe(OH)2 matrix and HAuCl4 as precursor, l-lysine as stabilizer and linker, Au nanoparticles coated onto γ-Fe2O3 substrate were in-situ synthesized at room temperature. The Au@Fe2O3 hybrid composites with small highly dispersed gold particles (∼3 nm) exhibited high catalytic activity towards 4-nitrophenol reduction and the oxidation of benzyl alcohol. The results indicated the rate constant for 4-nitrophenol reduction was 5.3 × 10−2 s−1, and displayed efficient catalytic performance in terms of turnover number (TOF) of 134.8 h−1 for the oxidation of benzyl alcohol at 90 ± 1 °C. Furthermore, the facial electrode potential-driven in situ synthesis method paved the way of other metal nanoparticles over Fe2O3.

Stebėdami žurnalistikos kaitą, kai miršta popierinis laikraštis sulig išeinančia karta, o žinios gali būti atnaujinamos kas akimirką elektroniniame leidinyje, ieškome atsakymo, kuo ji yra kitokia nei vakar. Juk žurnalistika turi būti ir toliau greitesnė, technologiškai spartesnė nei jos vartotojas – tai yra klasikinė naujienų pateikimo sąlyga. Ir naujienos reikšmė tebėra dvejopa: viena – tai žinia apie įvykį; kita – tai naujumas bet kurio žanro kūrinyje. Ir kai žinia pasiekiama ir pateikiama palyginti vis sparčiau, ar kiekvieno žanro žurnalistinis kūrinys gali būti lygiai taip pat sparčiai sukuriamas ir „patiekiamas“? Gali. Technologijos užtikrina spartumą. Būtent jos lemia įdomiausią kaitos ypatumą: išsiplečia žurnalistikos žanrų raiškos galimybės. Technologijos lėmė dienoraščio „atgimimą“: jis jau yra žurnalistikos žanrų sąraše, įgijo struktūrinių reikalavimų, būdingų informacijos kūriniui ir net tampa leidiniu. Straipsnyje, paaiškindami teismo bylą, susijusią su dienoraščio autoriaus teisėmis būti prilygintam žurnalistui, išnagrinėsime dienoraščio – žurnalistinio kūrinio vaidmenį (t.y. įvertindami dienoraštį kaip žurnalistikos žanrą).

Publicistika tarp liberalizmo ir tautiškumo
Authors: ŽALIENĖ Gustė Genovaitė
Published: July 2020

XIX amžiaus pabaiga sulig liberalizmo gūsiu naujoje lietuvių žurnalistikoje atskleidė sudėtingą socialinę problematiką, susijusią su laisvės siekiu lietuvių tautai, kitaip tariant – su tautinio tapatumo raiškos galimybėmis, tautų kultūromis, tradicijomis ir jų tarpusavio santykiais. Dabar ji taip pat atsiduria žiniasklaidos akiratyje, tačiau dėl kitų priežasčių: spaudos ir apskritai žodžio laisvė jau nagrinėjama kaip objektas be socialinės atsakomybės ribų, pilietiškumas interpretuojamas kaip dalykas, neturintis didelės praktinės vertės, nacionalistinė raiška apskritai vertinama kritiškai. O sąžiningas V. Kudirkos skaitymas tampa problema, kadangi temos, kurios buvo svarstomos ar aprašomos „Varpe“, dabar perkeliamos į visiškai kitokį XXI amžiaus politinį ir ekonominį kontekstą. Taigi ir paties įžymiojo varpininko publicistikos turinys transformuojamas į kitokią socialinės tikrovės erdvę. Tai net lemia kitokius, „šiuolaikiškus“ mūsų istorinės publicistikos vertinimus, kuriuos skleisti pradėjo būtent Vytautas Kavolis. Kyla klausimas, ar vertybių aspektu visuomenė yra visiškai pasikeitusi? Vilniaus universiteto žurnalistikos magistrantai siūlo tris interviu su filosofais, skirdami šią publikaciją V. Kudirkos 150-mečiui paminėti.

Authors: Martišius Mantas
Published: July 2020

Straipsnio objektas – praktinis psichologinio aspekto taikymas vykstant informaciniam karui. Straipsnyje aptariamos pagrindinės šiuolaikiškos informacinių operacijų sudedamosios dalys, informacinio karo pritaikymas nesant karinio konflikto. Pristatoma, kaip žiniasklaidos priemonėmis galima sukurti tariamą realybę, neigiamai konotuojančią aplinkos procesus. Informacinį karą prieš valstybę inicijuojančių šalių konstruojamas neigiamas vaizdas gali būti sistemingas ir sąmoningas, bet neatitinkantis tikrovės.Straipsnyje teoriniu aspektu aptariama, kaip naudojantis medijomis galima sukurti nepasitikėjimo aplinkiniais, savimi ir valstybe atmosferą ir taip palaužti piliečių norą ir gebėjimą pasipriešinti atvirai ar slaptai išorės agresijai. Prisidengiant demokratijos įtvirtinta žodžio laisve ir pliuralizmo idėja, lengvai skleidžiamos defetistinės nuotaikos, o tikrasis tokių veiksmų motyvas paprasčiausiai slepiamas.Esminiai žodžiai: defetizmas, informacinis karas, informacinės operacijos, medijos, realybės konstravimas.

Published: July 2020

El presente artículo tiene como objetivo principal analizar, desde la prensa de mayor tirada de Madrid, el curso de las elecciones autonómicas y municipales que se celebraron en España el 8 de mayo de 1983, a fin de examinar la argumentación y las posturas partidistas de cada uno de los diarios. La metodología se basa en el análisis de los editoriales y de los artículos de opinión que se publicaron en ABC, Diario 16 y El País desde el inicio de la campaña electoral hasta la valoración de los resultados en las urnas. Las principales conclusiones de este artículo señalan que, pese a sus diferencias ideológicas, todas las cabeceras coincidieron en que tras estas elecciones se ratificaba el bipartidismo y la demo-cracia en España, poniendo así fin al periodo transitorio acontecido tras la muerte de Franco.
Ópera italiana en San Petersburgo (siglo XVIII). Características de las óperas de Vicente Martín y Soler en el escenario teatral ruso
Authors: Kryazheva Irina
Published: July 2020

El artículo analiza las tendencias más importantes en el desarrollo de la música de la corte rusa del siglo XVIII. La época de las reformas de Pedro I creó las condiciones más favorables para que la música europea hiciera su entrada en la corte rusa y en la cultura urbana. Dominar los géneros y las formas de la música europea (italiana, francesa, alemana) y combinarlos con las tradiciones musicales nacionales es el principal vector de desarrollo de la cultura rusa del Setecientos. Durante el reinado de Catalina la Grande, estas tendencias se manifiestan en las obras del español Vicente Martín y Soler. Las características estilísticas de género de las llamadas «óperas rusas» del compositor, asociadas con la parodia de motivos y tramas de géneros épicos, se someten a un análisis más detallado, pues los rasgos estilísticos de la ópera seria también están sujetos a una reinterpretación cómica.

Significante versus inconsciente, contra-dicções: Ou, antes do signo, a o-posição; no início, a imagem
Authors: Moreira da Silva Manuel
Published: July 2020

Este trabalho discute a proposição lacaniana segundo a qual “o inconsciente é estruturado como uma linguagem” e sua fundamentação a partir da Antropologia de Lévi-Strauss. Em vista disso, discute o estatuto do significante (no quadro teórico do signo linguístico) como ser concreto e como representação vazia ou indeterminada, destituída de conteúdo ou significado e o da imagem fundante do mesmo, a qual se impõe como seu pressuposto essencial. Enfim, considera os limites e as contradições do significante para a tematização e a compreensão do inconsciente.

Authors: Costa Fábio Heleno Mourão da , Brasil Marília Carvalho
Published: July 2020

As reflexões deste artigo centram na análise do impacto dos royalties nas finanças e desenvolvimento do município de Coari-AM no período de 1991 a 2014. Para tanto, são apresentados os fundamentos econômicos (mainstrean e marxista) que geram a renda do setor petrolífero; o impacto na produção e arrecadação dessa compensação; a aplicação dos royalties em setores sociais e a relação destes gastos com o crescimento econômico e dinamismo da região. Tal empreitada se justifica pela possibilidade dos repasses de royalties reforçarem as receitas do município e, desta forma, verificar se este conseguiu encaminhar uma trajetória de oportunidades em prol do desenvolvimento local. Além da pesquisa bibliográfica, utilizaram-se os dados do Ipeadata, ANP, Tesouro Nacional, RAIS-MTE e IBGE, de forma a permitir analisar o desenvolvimento, o crescimento e as potencialidades locais.
