Refractive index and group velocity of electromagnetic modes in a relativistic Fermi gas at finite temperatures
Authors: Mazo-Vasquez J. D. , Hincapie-Zuluaga L. M. , Reyes-Gómez E.
Published: January 2020

A theoretical study of the optical properties of a relativistic Fermi gas at a finite temperature is performed. The results are obtained from Maxwell’s equations, assuming bianisotropic constitutive relations for the relativistic gas. The longitudinal and transverse spatial directions are defined according to the properties of the electric permittivity tensor. The electromagnetic modes and the refractive index of the relativistic gas are calculated along such directions. The longitudinal and transverse group velocities corresponding to the respective propagation modes are also obtained. No typical characteristics of metamaterials are observed, neither in the refractive index nor in the group velocities corresponding to the transverse modes. However, in the case of longitudinal modes, negative values of the group velocity are observed in a region of the reciprocal space where particle–antiparticle excitations can occur.

Published: January 2020

Precision spectroscopy of fundamental bands of molecules in the mid-infrared (MIR) region is of great interest in applications of trace detection and testing fundamental physics, where high-power and narrow-linewidth MIR lasers are needed. By using a frequency-stabilized near-infrared laser as a seed of the signal light of a continuous-wave optical parametric oscillator, we established a broadly tunable MIR light source that has an output power of several hundred milliwatts and a linewidth of a few tens of kilohertz. The MIR laser frequency drift was reduced to below 1 kHz by using an optical frequency comb to stabilize the frequency of the 1064 nm pumping laser. The performance of the light source was investigated and tested by measuring the saturated absorption spectroscopy of a few molecular transitions at 3.3 µm.
AGRONOMIC CHARACTERS OF DROUGHT-TOLERANT SOYBEANS AT THE REPRODUCTIVE STAGE
Authors: Adie M. Muchlish , Krisnawati Ayda
Published: January 2020

In Indonesia, soybeans are typically cultivated during the dry season, thus making it prone to drought stress in the reproductive stage. The objective of the research was to characterize the agronomic characters of several soybean genotypes which were tolerant to drought at the reproductive stage. A total of 19 soybean genotypes were evaluated for its agronomic characters and tolerance to drought stress in Probolinggo (East Java, Indonesia) during the dry season (June – September). The research was arranged in a randomized block design with four replicates. Soybean cultivars were sown at two separate experiments, normal/optimal (plants were irrigated during the growth period) and stress (plants were irrigated up to 40 days after planting) conditions. Drought stress during the reproductive stage did not affect the characters of plant height, the number of branches per plant, the number of nodes per plant, and the number of pods per plant. Meanwhile, the number of empty pod, seed weight per plant, and seed yield were significantly affected. There were two genotypes which were identified as the tolerant genotypes to drought stress at the reproductive stage, i.e. MDT15-6-11 and MDT15-W-3034. The agronomic characters of MDT15-6-11 were showed as having a low percentage of yield reduction, hence it was able to mantain its high yield. The MDT15-W-3034 was identified as drought-tolerant due to the slow wilting, high plant character, a slow vegetative phase, and high yields. The genotypes obtained from this study could be recommended to be released as new soybean drought-tolerant varieties due to its high yield and tolerant to drought stress. Those genotypes could also be used as gene donors for soybean improvement to drought stress at the reproductive stage.

From Goldilocks to Gump: entrepreneurial mechanisms for everyday entrepreneurs
Authors: Sarasvathy Saras D. , Forster William , Ramesh Anusha
Published: January 2020

In this essay we argue that the exclusive focus on research aimed at isolating the characteristics of entrepreneurs as opposed to others, while intellectually exciting and even practically valuable, may have blinded us to another wholly new and exciting possibility – namely, the design of mechanisms that allow all kinds of individuals to start new ventures and provide useful and valuable tools to enable them and their stakeholders to build enduring organizations.  The research stream on effectuation has identified a few of these mechanisms.  By showing where effectuation may be located within the history of behavioral and experimental economics, we were led to the outline of at least three more mechanisms that could open the door to an entirely new research agenda on entrepreneurial mechanisms design that parallels the effort in experimental economics on economic systems design.
Factors of vascular calcification in patients with type 2 diabetes mellitus on long-term dialysis
Authors: Archakova Tatyana , Nedosugova Ludmila V.
Published: December 2019

Purpose Defining vascular calcification markers in patients on long-term hemodialysis (LTH) with type 2 diabetes mellitus (type 2 diabetes) and without type 2 diabetes.
Materials and methods. The study was conducted in 82 patients with chronic kidney disease (CKD) (51 men, 31 women) on LTH, of which 25 patients (10 men, 15 women) had type 2 diabetes and 57 people (33 men, 24 women) had no diabetes. All patients underwent evaluation of calcium-phosphate metabolism, control of intact PTH (iPTH), inorganic phosphorus, and total calcium. All patients were tested for the level of fibroblast growth factor-23 (FGF-23) in blood serum using a multi-enzyme immunoassay kit, and the correlation between these parameters and the presence of vascular calcification was evaluated.
Results. A correlation was found between the severity of vascular calcification and the calcium-phosphate metabolism. In the group with type 2 diabetes, there is a correlation between the level of FGF-23, iPTH, inorganic phosphorus and vascular calcification. There is also a correlation between the time on LTH and the increase in the level of FGF-23 in patients with type 2 diabetes.
Conclusion. We obtained data that can indicate a more pronounced change in the vascular wall in patients with type 2 diabetes on LTH in comparison with patients without diabetes mellitus on LTH, which allows to associate high cardiovascular mortality in patients with type 2 diabetes on LTH with accelerated development of vascular calcification.
Special aspects of concentrated insulins: basic characteristics and research findings
Authors: Demidova Tatiana Y. , Balutina Olga V.
Published: December 2019

The appearance of concentrated insulins in clinical practice determines the need to analyze product priorities in appropriate groups of patients with diabetes. The aim of this article is to summarize the literature on concentrated insulins (i.e. insulin lispro 200 units/mL, insulin degludec 200 units/mL, insulin glargine 300 units/mL) from randomized controlled trials, derive guidance on appropriate and safe use of these agents and demonstrate experience in real clinical practice. Severe hypoglycemia in all studies was generally low (though higher with prandial plus concentrated basal analogue therapy), and statistical improvements in other hypoglycemia categories were observed for concentrated basal insulins versus insulin glargine 100 units/mL. In all analyzed data hypoglycemic effect of insulin glargine 300 units/mL was equitable to insulin glargine 100 units/mL. Other important findings demonstrate more constant and prolonged insulin action with low within-subject/ between-day variability for insulin glargine 300 units/mL versus insulin glargine 100 units/mL, therefore, more physiological treatment might prevent from diabetic microvascular complications. The results of randomized trials are comparable with our clinical practice experience and indicate efficacious and safe glucose-lowering properties without risk of severe hypoglycemia.

Authors: Lays Correa da Silva
Published: December 2019

O Informe produzido pela Comisión Chilena por la Verdad y Reconciliación, instaurada logo após a transição política chilena, denunciava os crimes cometidos pela Ditadura Militar entre 1973 e 1990. A repressão ditatorial atingiu partidos políticos de esquerda, sindicalistas, camponeses, estudantes, artistas e pessoas ligadas ao governo da Unidade Popular. Além disso, grupos que tradicionalmente sofreram a repressão do Estado chileno, como os mapuche foram alvo das violações de Direitos Humanos ocorridas no período. Neste artigo buscamos analisar como a questão mapuche foi tratada pelo Informe, trazendo à tona a atuação política desse grupo durante a transição chilena e debates acerca do tema da Justiça de Transição.

Data Management Plans A Review
Authors: Vitale Cynthia Hudson , Moulaison Sandy Heather
Published: December 2019

With increasing world-wide emphasis on providing access to research data, data management plans (DMPs) have emerged as the expected way for researchers to formalise and communicate their intentions to stakeholders, including to their funders. This review paper focuses on a thematic analysis and presentation of empirical research on DMPs, a literature that is surprisingly limited, likely due to the young age of the field. Research shows that, despite the benefits associated with data sharing, DMPs have potential that is not being realised to the fullest. Researchers in scholarly communication and information science primarily have evaluated DMPs using text analysis methodologies, often supplementing them with surveys or interviews. Future study, especially in areas of machine-actionable DMPs is promising; such research is needed to further explore how DMPs can best be utilised to support data sharing.
Theoretical analysis of particle size re-distribution due to Ostwald ripening in the fuel cell catalyst layer
Authors: Kregar Ambrož , Katrašnik Tomaž
Published: January 2020

The limited durability of hydrogen fuel cells is one of the main obstacles in their wider adoption as a clean alternative technology for small scale electricity production. The Ostwald ripening of catalyst material is recognized as one of the main unavoidable degradation processes deteriorating the fuel cell performance and shortening its lifetime. The paper systematically studies how the modeling approach towards the electrochemically driven Ostwald ripening in the fuel cell catalyst differs from the classical diffusion driven models and highlights how these differences affect the resulting evolution of particle size distribution. At moderately low electric potential, root-law growth of mean particle size is observed with linear relation between mean particle size and standard deviation of particle size distribution, similar to Lifshitz-Slyozov-Wagner theory, but with broader and less skewed distribution. In case of high electric potential, rapid particle growth regime is observed and qualitatively described by redeposition of platinum from a highly oversaturated solution, revealing the deficiencies of the existing platinum degradation models at describing the Ostwald ripening in the fuel cells at high electric potentials. Several improvements to the established models of platinum degradation in fuel cell catalysts are proposed, aimed at better description of the diffusion processes involved in particle growth due to Ostwald ripening.
Dizziness and localized pain are often concurrent in patients with balance or psychological disorders
Authors: Malmström Eva-Maj , Magnusson Måns , Holmberg Johan , Karlberg Mikael , Fransson Per-Anders
Published: December 2019

Background and aims

Symptoms of dizziness and pain are both common complaints and the two symptoms often seem to coincide. When symptoms appear concomitant for sustained periods of time the symptoms might maintain and even exacerbate each other, sometimes leading to psychological distress. In order to evaluate such comorbidity we studied patients referred to a vestibular unit and to a psychiatric outpatient clinic with respectively balance disorders and psychological issues.

Methods

Consecutive patients referred to a vestibular unit (n = 49) and a psychiatric outpatient clinic (n = 62) answered the Dizziness Handicap Inventory (DHI) questionnaire and a questionnaire detailing occurrence of dizziness and pain.

Results

The experience of dizziness and pain often coincided within individuals across both clinical populations, especially if the pain was located to the neck/shoulder or the back (p = 0.006). Patients who reported dizziness had significantly more often pain (p = 0.024); in the head (p = 0.002), neck/shoulders (p = 0.003) and feet (p = 0.043). Moreover, patients who reported dizziness stated significantly higher scoring on emotional (p < 0.001) and functional (p < 0.001) DHI sub-scales. Furthermore, patients who reported an accident in their history suffered significantly more often from dizziness (p = 0.039) and pain (p < 0.001); in the head (p < 0.001), neck/shoulders (p < 0.001) and arms (p = 0.045) and they scored higher on the emotional (p = 0.004) and functional (p = 0.002) DHI sub-scales.

Conclusions

The findings suggest comorbidity to exist between dizziness and neck/shoulder or back pain in patients seeking health care for balance disorders or psychological issues. Patients suffering from dizziness and pain, or with both symptoms, also reported higher emotional and functional strain. Thus, healthcare professionals should consider comorbidity when determining diagnosis and consequent measures.

Implications

Clinicians need to have a broader “receptive scope” in both history and clinical examinations, and ask for all symptoms. Although the patients in this study visited a vestibular unit respectively a psychological clinic, they commonly reported pain conditions when explicitly asked for this symptom. A multimodal approach is thus to favor, especially when the symptoms persist, for the best clinical management.

The local technical validation of new plasma tube with a mechanical separator
Authors: Ucar Kamil Taha , Aksoy Neval , Erhan Belgin , Bercik Inal Berrin
Published: December 2019

Background

Unsuitable samples are common problem for laboratories. The blood collection tubes need to be validated or verified prior to their being used in the routine laboratory for reducing this situation.

Objective

We aim to compare the technical qualifications of routinely used BD Vacutainer® Serum Separator Tubes™ II Advance Plus with BD Vacutainer® Barricor™ LH Plasma Tubes for local technical validation.

Materials and methods

Apparently healthy 150 voluntary subjects were enrolled in the study. Samples were collected in two separated tubes by a single phlebotomist. Twelve quality indicators were used to compare these two different types of tubes for local technical validation. Differences (%) between them were calculated with the formula proposed by EFLM. In case of any difference of less than 1% for each indicator, the evaluated tube was considered as non-inferior.

Results

Indicators, such as tubes with physical defects, that fail to create vacuum, not properly fitting into the blood collection device, under filling (10%), cracked tubes, tubes exterior surface contaminated with blood, hemolysed specimens, including fibrin strand/mass in the sample, red blood cell adhesion, poor/incomplete barrier formation were found non-inferior in Barricor™ tubes. White particulate matter (WPM) was observed in 24.6% of Barricor™. Therefore, the last indicator (tubes including gel/foreign material/WPM in sample after centrifugation) was found inferior for Barricor™.

Conclusion

Technical local validation studies should be encouraged in terms of quality management. It was thought that WPM would not cause any interference in a properly filled tube. In addition to, Barricor™ was also found to be technically acceptable when evaluated through using all other indicators.
Wie kann günstiger Wohnraum definiert werden und was sind sinnvolle Maßnahmen, um diesen zu erweitern?
Authors: Bacher Johann , Tamesberger Dennis
Published: January 2020

Der vorliegende Beitrag untersucht, wie günstiger Wohnraum definiert werden kann, wie hoch die Anzahl an günstigen Mietwohnungen in Österreich ist und welche Einflussfaktoren es gibt. Durchgeführt wird eine Sekundärdatenanalyse des Mikrozensus des Jahres 2017. Als günstig wurden dabei in Anlehnung an das Konzept des Kantons Luzern Wohnungen bezeichnet, deren Hauptmiete weniger als 70 % der Durchschnittsmiete in Österreich beträgt. In Bezug auf die ausgewählten Haushalte mit einem Nettoeinkommen knapp über der Einkommensgrenze der Wohnbeihilfe resultieren Mietkostenbelastungen von 21 % bis 25,7 %. Von einem sozial-politischen Standpunkt aus betrachtet stellt die 70 %-Schwelle eine sehr ambitionierte Zielsetzung dar. In Österreich erfüllen 398.000 Hauptmietwohnungen bzw. 24 % aller Hauptmietwohnungen dieses Kriterium. Allerdings wurden von diesen Wohnungen nur 70.400 in den letzten drei Jahren vermietet. Als wichtige Strategie erscheint daher nicht nur mehr Wohnungen zu bauen, sondern vor allem den Anteil an günstigen Hauptmietwohnungen bei Neubauten bzw. Neuvermietungen zu erhöhen.
No Effect of Red on Personality Trait Self-Ratings: Testing for Effects of Font Color
Authors: Wolf Daniel , Schütz Astrid
Published: December 2019

Unlike most other mammals, humans are trichromats and have the ability to perceive the color red. An explanation for the evolution of humans’ trichromatic color vision is that it offers humans the advantage to detect ripe fruit. Apart from this explanation, psychological theories have proposed that color, especially the color red, conveys information that affects psychological functioning, but results have been mixed. Whereas studies have extensively tested effects of red on performance measures, it is unclear whether this effect generalizes to self-ratings, one of the most frequently used methods in psychological research. In line with theory and empirical evidence, we argue that exposure to red can lead to distorted responses in self-ratings on the basis of the same underlying mechanism that affects results on performance measures. We varied the font color (hue values) of self-ratings in two online studies. In a first exploratory study, we found an effect of font color on personality trait self-ratings (N = 145). We attempted to rigorously replicate this finding in a larger sample (N = 1,007) but did not detect any effect. The findings underline the importance of rigorous research on effects of color on psychological functioning and call into question the proposition that red has ubiquitous effects.
Evaluation of simulated O3 production efficiency during the KORUS-AQ campaign: Implications for anthropogenic NOx emissions in Korea

We examine O3 production and its sensitivity to precursor gases and boundary layer mixing in Korea by using a 3-D global chemistry transport model and extensive observations during the KORea-US cooperative Air Quality field study in Korea, which occurred in May–June 2016. During the campaign, observed aromatic species onboard the NASA DC-8 aircraft, especially toluene, showed high mixing ratios of up to 10 ppbv, emphasizing the importance of aromatic chemistry in O3 production. To examine the role of VOCs and NOx in O3 chemistry, we first implement a detailed aromatic chemistry scheme in the model, which reduces the normalized mean bias of simulated O3 mixing ratios from –26% to –13%. Aromatic chemistry also increases the average net O3 production in Korea by 37%. Corrections of daytime PBL heights, which are overestimated in the model compared to lidar observations, increase the net O3 production rate by ~10%. In addition, increasing NOx emissions by 50% in the model shows best performance in reproducing O3 production characteristics, which implies that NOx emissions are underestimated in the current emissions inventory. Sensitivity tests show that a 30% decrease in anthropogenic NOx emissions in Korea increases the O3 production efficiency throughout the country, making rural regions ~2 times more efficient in producing O3 per NOx consumed. Simulated O3 levels overall decrease in the peninsula except for urban and other industrial areas, with the largest increase (~6 ppbv) in the Seoul Metropolitan Area (SMA). However, with simultaneous reductions in both NOx and VOCs emissions by 30%, O3 decreases in most of the country, including the SMA. This implies the importance of concurrent emission reductions for both NOx and VOCs in order to effectively reduce O3 levels in Korea.
La naturaleza epistemológica de las ecovilas: Revisión sistemática en las tesis defendidas en programas de postgrado en Brasil
Authors: Tres Guilherme Smaniotto , Souza Washington Jose de
Published: December 2019

Este estudio tiene como objetivo comprender mejor cómo el campo de estudio sobre el fenómeno social ecovila ha sido desarrollado en Brasil. Una revisión sistemática de las tesis de doctorado defendidas en Brasil sobre el tema fue realizada y la propuesta de Burrel y Morgan sobre los paradigmas del pensamiento sociológico sirvió como guía. Las tesis se encuadran predominantemente en el paradigma humanista radical, que es caracterizado por la manera de ver el mundo de modo subjetivo, acepta la idea que el individuo crea e interpreta el mundo en que vive, y asume conflictos y contradicciones estructurales como intrínsecos a la sociedad,. Los estudios evidencian una organización social compleja, que buscan discutir, además de la pauta ecológica, la solidaridad, calidad de vida, educación, espiritualidad y consumo responsable. El concepto nacional sobre ecovilas emerge, de esa forma, como la búsqueda de un ideal de libertad, de respeto y mutualismo entre los individuos, el colectivo y la naturaleza.

The research of financing the socio-economic development of the region at the expense of local budgets was conducted. Particularly, the conceptual foundations of socio-economic development budget financing have been further developed in terms of determining the directions of using resources that ensure the effectiveness of socio-economic development, systematic financial instruments of social development of the region, and supplemented in the allocation of grants and programs of the State Fund for Regional Development.On the basis of the analysis of budget expenditures, the analysis of financial support of socio-economic development of Ukraine and Ivano-Frankivsk region was carried out. In particular, the expenditures of the general and special fund of the Ivano-Frankivsk regional budget for financing the main directions of socio-economic development of the region were analyzed, the main trends were identified and problems were identified.Despite of important tasks that local governments face up when formulating and using development budgets, they are now mostly used to simplify individual budgetary procedures. In addition, the miserable sumes of local budget development revenues are directed, for the most part, to capital expenditures, to the repairs of social facilities, but not to investments in socio-economic development programs. Therefore, the development budget, as a mechanism for making budget investments, needs to be reformed and improved, due to the limitations on filling this fund with financial resources, the inefficient mechanism for its use and control over the level of efficiency.The state of socio-economic development of Ukraine can be concluded on the basis of statistical indicators characterizing trends in the social and economic spheres. Based on the data of the State Statistics Service, the importance of these indicators in 2015 – 2018 was highlighted. This helped to indicate a number of positive trends within the economic component of socio-economic development and the negative dynamics of some social indicators. It allowed justifying recommendations for improving the effectiveness of financing the socio-economic development of the region.

Анотація. У статті подано визначення внутрішніх комунікацій, які покликані дати можливість працівникові зрозуміти корпоративну культуру, цілі і цінності організації. В статті виділено основні ознаки ефективних внутрішніх комунікацій: інформативність; ясність; своєчасність; незалежність і неупередженість; лаконічність. Водночас, визначено якості працівників, які займаються формуванням внутрішніх комунікацій, а саме: відкритість, чесність, здатність до діалогу. У роботі розглянуто канали внутрішніх комунікацій: вертикальні, горизонтальні та внутрішні.

Особливу увагу приділено системі внутрішніх комунікацій, яка є комплексом інформаційних каналів, що дають можливість надавати дані ділового, інтелектуального і емоційного характеру всередині організації між співробітниками. Розглянуто основні інструменти внутрішніх комунікацій: інформаційні, комунікативні, аналітичні і організаційні. Виділено основні аспекти оцінки дієвості системи внутрішніх комунікацій, а саме кількість комунікаційних каналів; якість виконання робіт, які вимагають одночасної замученості різних підрозділів; кількість проміжних ланок при передачі інформації; своєчасність розповсюдження інформації; наявність балансу між вертикальними і горизонтальними комунікаціями всередині компанії, між документованими і формальними засобами; стан соціально-психологічного клімату в колективі; кількість неформальних комунікацій. Висвітлено питання аудиту внутрішніх комунікацій, ефективність якого і ставлення до якого персоналу всіх категорій багато в чому залежить від того, які дії зроблять менеджери за його підсумками, а також від ступеня прозорості і доступності результатів.Дане питання потребує подальшого вивчення з метою деталізації процесу побудови організаційних комунікацій.

Neste artigo, objetivamos verificar a forma como os personagens das obras de Arthur Conan Doyle, Sherlock Holmes e Dr. Watson, são (re)construídos e (re-) apresentados para a televisão contemporânea na série Sherlock. Realizando uma análise estilística do episódio piloto, observamos os mecanismos de apresentação dos personagens, evidenciando os recursos estéticos e narrativos utilizados pelos criadores da série para “atualizar” os personagens para o século XXI. Entendemos que a indústria televisiva possui características bastante específicas que influenciam em seu estilo, ainda que algumas características se aproximem da indústria cinematográfica, o estilo televisivo tem sua história e especificidades. Com isso, demonstramos como a série dispõe de recursos audiovisuais para modernizar o método investigativo-dedutivo que tornou o personagem mundialmente conhecido.

Authors: Mendonça Carla , Duarte Jéssica
Published: December 2019

Este artigo apresenta uma análise das eleições municipais de 2008, 2012 e 2016 em Porto Alegre, capital do estado do Rio Grande do Sul (RS), Brasil, a partir da construção de um quadro comparativo entre o comportamento dos eleitores e as estratégias de comunicação das coligações. São analisadas características históricas do eleitorado, resultados eleitorais e estratégias de comunicação eleitoral, e, finalmente, são comparados os dados dos candidatos vitoriosos nos três pleitos. Busca-se identificar os modelos mais bem-sucedidos de comunicação eleitoral nesses pleitos e se há padrão histórico de comunicação eleitoral que leve os candidatos ao poder ou se novas estratégias vêm sendo agregadas aos processos. Identificamos a repetição de temas, abordagens e uso de mídias nos dois primeiros pleitos, com inflexão na última eleição, a de 2016.
“Se ela é não-binária, por que se referem no feminino?”: um corpo estranho em disputa
Authors: Henn Ronaldo Cesar , Dias Marlon Santa Maria
Published: December 2019

O artigo analisa os sentidos sobre as concepções de gênero oriundos do caso envolvendo um crime contra uma pessoa não binária. O mapeamento é feito em 1512 comentários de leitores em duas publicações referentes ao caso no Facebook – uma do jornal O Globo e outra do programa televisivo Fantástico. Por meio da Análise de Construção de Sentidos em Redes Digitais, metodologia para o estudo de ciberacontecimentos, constatou- -se a emergência de sete constelações de sentido: alteridade e reconhecimento; deboche; caráter pedagógico; enfoque no crime e deslegitimação do gênero; desqualificação do jornalismo; desejo de morte; e normalização. Orientados pela cristalização de construções histórico-culturais sobre o gênero, os sentidos identificados potencializam os processos de desumanização de corpos dissidentes à norma cisgênera e heterossexual.

Este artigo tem por objetivo analisar como professores iniciantes, atuantes em duas universidades públicas do Estado do Rio Grande do Sul, vivenciaram o início da profissão, visando compreender os enfrentamentos e os silenciamentos produzidos no desempenho das atividades acadêmicas. A metodologia da pesquisa é qualitativa, sendo organizada por meio dos dados provenientes de entrevistas semiestruturadas realizadas com 14 professores iniciantes de duas universidades públicas: a Universidade Federal do Rio Grande (FURG) e a Universidade Federal de Santa Maria (UFSM). Para a interpretação dos dados, optamos pela Análise de Conteúdo de Minayo (2010). Como resultados, evidenciamos que os professores sentem-se inseguros no desenvolvimento das atividades de ensino, pressionados pelas demandas da produção científica e inaptos para atuarem na gestão universitária. Para lidar com os cenários desafiadores, os professores desenvolvem estratégias de resiliência, como o desenvolvimento da autoestima, o diálogo com colegas e a reflexão sobre a prática docente. Concluímos que as universidades precisam incluir processos e programas de formação pedagógica nos planos de desenvolvimento institucional, aliando iniciativas de auto e ecoformação; integrar as ações de recepção e de adaptação dos professores entre as pró-reitorias e as unidades acadêmicas, bem como criar espaços formativos para o desenvolvimento de competências profissionais vinculadas ao desenvolvimento das atividades de ensino, pesquisa, extensão e gestão.
On the classification of homoclinic attractors of three-dimensional flows

For three-dimensional dynamical systems with continuous time (flows), a classification of strange homoclinic attractors containing an unique saddle equilibrium state is constructed. The structure and properties of such attractors are determined by the triple of eigenvalues of the equilibrium state. The method of a saddle charts is used for the classification of homoclinic attractors. The essence of this method is in the construction of an extended bifurcation diagram for a wide class of three-dimensional flows (whose linearization matrix is written in the Frobenius form). Regions corresponding to different configurations of eigenvalues are marked in this extended bifurcation diagram. In the space of parameters defining the linear part of the considered class of three-dimensional flows bifurcation surfaces bounding 7 regions are constructed. One region corresponds to the stability of the equilibrium states while other 6 regions correspond to various homoclinic attractors of the following types: Shilnikov attractor, 2 types of spiral figure-eight attractors, Lorenz- like attractor, saddle Shilnikov attractor and attractor of Lyubimov-Zaks-Rovella. The paper also discusses questions related to the pseudohyperbolicity of homoclinic attractors of three-dimensional flows. It is proved that only homoclinic attractors of two types can be pseudohyperbolic: Lorenz-like attractors containing a saddle equilibrium with a two-dimensional stable manifold whose saddle value is positive and saddle Shilnikov attractors containing a saddle equilibrium state with a two-dimensional unstable manifold.

Phthorimaea operculella is a significant insect pest of cultivated potatoes in tropical and subtropical regions such as Iran. Since the potato is one of the most valuable sources of human food, non-chemical control of potato pests is essential. Application of medicinal plant extracts is a low-risk alternative method to synthetic chemical insecticides. Hence, the present study was conducted to investigate a potential strategy to improve the insecticidal activity of plant extracts for efficient management of P. operculella. The insecticidal efficacy of pure methanolic extract (PME) and Fe3O4@methanolic extract (FME) of Cuminum cyminum were evaluated against the potato tuber moth under laboratory conditions. The morphological characteristics of Fe3O4@Cumin were investigated by scanning electron microscope. Magnetic properties of the samples were determined using a vibration sample magnetometer. XRD was used to prove the crystalline structure of Fe3O4@Cumin. SEM, FTIR, XRD, and VSM analyses confirmed that the methanolic extract was loaded on Fe3O4. The toxicity of PME and Fe3O4@Cumin were evaluated on one-day-old eggs and penetration the first instar larvae of P. operculella into potato tubers and leaves. The LC50 values of Cumin extract and Fe3O4@ Cumin were 961.07 and 601.48 and 496.84 and 268.82 ppm for penetrating neonate larvae to tubers and leaves, and 874.90 and 595.16 ppm for eggs, respectively. Bioassays revealed that Fe3O4@Cumin was more toxic than non-formulated Cumin methanolic extract against eggs and neonate larvae of P. operculella. The formulated methanolic extract was significantly more repellent against the pest. Our results suggested that the prepared nanocomposite could be used as a new effective tool for P. operculella management strategies to protect potatoes.

Bacillus thuringiensis (B.t) is well known for its biocontrol potential against a variety of insects. Nematicidal potential of ten B.t isolates was tested against root-knot nematodes (Meloidogyne javanica (Treub) Chitwood) in vitro, under greenhouse as well as in field conditions. Eggs and second stage juveniles (J2) were exposed to 5 and 25% concentrations of bacterial cell-free aqueous extracts up to 96 h. B.t isolates showed lesser degrees of nematicidal activity at 5% concentration. However, some B.t isolates (B.t-14, B.t-16 and B.t-64) greatly reduced egg hatching and increased J2. All B.t isolates revealed suppressed egg hatching and increased mortality of J2 at 25% concentration. Soil applications with most of the B.t isolates under greenhouse and field conditions significantly improved height and fresh weights of root-knot nematode parasitized okra (Abelmoschus esculentus (L.) Moench). Some isolates, including B.t-64 reduced the number of galls and egg masses. B.t-64 reduced gall formation up to 70% under greenhouse conditions. However, 29% of decrease was observed in field conditions. Similarly, B.t-64 treated plants showed a 56% decreased in eggs/egg mass in a field experiment. Population of root-knot nematodes in the rhizosphere was decreased up to 61% in the field experiment as compared to control.
