¿Un etnográfo entre los archivos? Propuestas para una especialización de conveniencia
Authors: Bosa Bastien
Published: October 2020

Este artículo pretende brindar una reflexión sobre la idea de “etnografía de/en los archivos”. En la primera parte, se desarrolla una crítica tanto de las separaciones disciplinares entre antropología e historia como de la interdisciplinariedad concebida como “alianza de disciplinas”. En la segunda, se formula una propuesta alternativa, basada, por un lado, en la defensa de una concepción unificada de las ciencias sociales, y por otro, en la voluntad de definir un “espacio de trabajo” especializado, alredor de la aplicación del programa metodológico de la etnografía en terrenos históricos. Más que hablar de las relaciones entre dos disciplinas, preferimos hacerlo sobre las relaciones entre dos niveles: 1) Un objeto (el pasado), que se presenta como específico a la historia, pero que realmente interesa al conjunto de los científicos sociales. 2) Una técnica (la etnografía), que a veces se presenta como específica a la antropología, pero que también interesa al conjunto de las ciencias sociales.
La patrimonialización como protección contra la mercantilización: paradojas de las sanciones culturales de lo igual y lo diferente
Authors: Montenegro Mauricio
Published: October 2020

Este texto afirma que el patrimonio es un tipo de producción cultural que, en sus esfuerzos por proteger otras producciones culturales, ha usado de manera sostenida lógicas y modelos de aislamiento, oposición y valoración propios de la esfera de los intercambios económicos. En el patrimonio opera una suerte de economía cultural y, por tanto, estudiarlo desde esta perspectiva puede ser útil para pensar su definición, sus límites y sus determinaciones. Por otra parte, este texto plantea que el mercado contemporáneo se ordena sobre un modelo cultural, que he decidido llamar “producción de singularidad cultural”, tendiendo una red de producción de valor que, de forma paradójica, encuentra su principio de valoración en la defensa de lo invaluable, en su protección. De allí que patrimonialización y mercantilización aparezcan fuertemente asociadas aquí.
“En la corriente viajan…”
Authors: Orrantia Juan
Published: October 2020

En Colombia las aguas de ríos como el Magdalena han sido escenario de la expresión del terror y el olvido. Sin embargo, en este ensayo quiero proponer una mirada alternativa del agua y su relación con la violencia. A partir del proceso de la fermentación como metáfora y realidad material, sugiero la posibilidad de imaginar una forma de memoria sensual que se genera por medio de la interacción con agua saturada con historias de terror. Para esto utilizo una serie de fragmentos etnográficos y fotografías de la vida diaria en el pueblo de Nueva Venecia en la Ciénaga Grande, donde el agua que fue impregnada por los residuos de una masacre se filtra en espacios, instantes y escenarios del diario vivir. Estos momentos plantean la posibilidad de leer esta relación con el agua y sus residuos como parte de una narrativa de memoria en vez de olvido.
Lights, Action, Naughty Bits: A Thematic Analysis of New Zealanders’ Attitudes to Naked Attraction
Authors:   Auckland University of Technology, Nairn Angelique , Matthews Matthews ,   Auckland University of Technology
Published: October 2020

The sexualisation of culture has generated much debate in western discourse around its effect on the normalisation of nudity and sexual activity. The reality television show Naked Attraction has increased the dialogue around this debate after its airing, originally in the UK, and then in international territories. The show has been applauded for profiling diverse people, whether that be concerning sexual orientation, body image, gender or ethnicity. However, it has also been accused of showcasing pornography. To explore where New Zealanders’ attitudes were positioned on the show, we thematically analysed online comments from two local media entities and found that New Zealanders were positive on its nudity and approach to sexual discourse.

Authors: ÇAKMAK Recep , ÇAKANEL Ahmet
Published: October 2020

Intelligent technologies have become pioneer force to provide flexible, dynamic and efficient energy generation and management. Thus, smart algorithms such as fuzzy logic, artificial neural network, machine learning, soft computing techniques are sole remedy against growing diverse and numerous distributed generations that make more complicated power system. Real time closed loop controlling requires energy price as a featured variable to procure supply demand equilibrium point for stable and reliable power system operation, where several dynamic models and estimation software are introduced in the literature. In this study, a fuzzy logic reasoning based price regulator (FLR-PR) is designed and simulated on MATLAB/Simulink environment using 2018 hourly data of a summer day taken from annual energy report of Turkey. Proposed model has been compared based on performance indexes to Proportional Integral Derivative (PID) price controller in the constituted simulation cases. FLR-PR tracks instant reference demand signal changes with minimum steady state error and fast transient response with respect to PID controller.
Existence of regular nut graphs and the fowler construction
Authors: Gauci Baptist , Pisanski Tomaz , Sciriha Irene
Published: October 2020

In this paper the problem of the existence of regular nut graphs is
addressed. A generalization of Fowler?s Construction which is a local
enlargement applied to a vertex in a graph is introduced to generate nut
graphs of higher order. Let N (?) denote the set of integers n such that
there exists a regular nut graph of degree ? and order n. It is proven that
N (3) = {12} ? {2k : k ? 9} and that N (4) = {8, 10, 12} ? {n : n ? 14}.
The problem of determining N (?) for ? > 4 remains completely open.

Effect of robot-assisted gait training on biomechanics of ankle joint in patients with post-stroke hemiparesis
Authors: Klochkov AS , Zimin AA , Khizhnikova AE , Suponeva NA , Piradov MA
Published: October 2020

The key factor promoting post-stroke gait disturbances is motor impairment of the ankle joint (AJ) which results in pathological synergies. Robotic devices used for gait training are equipped with hip and knee joint actuators. However, there is no consensus in the literature on their effect on AJ movements. The aim of this study was to investigate the effect of robot-assisted gait training on AJ movements in patients with post-stroke paresis. The study recruited 22 hemispheric stroke survivors. They motor function was assessed using clinical scales and motion capture analysis. All patients received 11 robot-assisted gait training session. After rehabilitation, the total score on the Fugl-Meyer Assessment scale increased from 146.5 to 152 points (p < 0.05); for the lower limb, the score increased from 18 to 20.5 points (p < 0.05). The muscle tone of ankle extensors decreased from 2.5 to 2.0 points on the modified Ashworth scale (p < 0.05). The duration of the stance phase increased from 28.0 to 33.5% relative to the total gait cycle (GC). The main difference in the GC structure before and after rehabilitation is the presence of 3 GC parts instead of 5, suggesting consolidation of patients’ goniograms at 1-61% of GC. Comparison of joint angles before and after rehabilitation revealed that only the interquartile ranges (IR) were different (р < 0.05). The authors conclude that robot-assisted training with knee and hip joint actuators indirectly affects the kinematic parameters of AJ by promoting a shift towards the average gait kinematics.

Authors:   , Page Victoria
Published: October 2020

This study is an exploration of the intersectionality of my two identities, lesbian and social worker, within the northern British Columbia (BC) mental health workspace. By taking a transformative stance and making use of queer methodology, I present my voice as both the researcher and the researched. My data sources are based on past recollections and a collection of personal poems, reflections, stories, journal entries, sketches, collages, and photographs. Through autoethnographic accounts, I examine experiences as my identities intersect and become the focus of workplace bullying and harassment within the setting of northern British Columbia (BC) mental health system. I also examine the personal and professional costs of using internal agency and provincially legislated protocols and policies in challenging workplace bullying and harassment behaviour, such as the little-known topic of disenfranchised grief.

The problem of analyzing and evaluating the structure of FPGA routing resources at early stages of the design flow presents great interest for researchers. Until now, an approach, consisting in passing the full design flow (logic synthesis, placement, routing) on a set of the test circuits with subsequent estimation of various parameters for each FPGA architecture being analyzed, had been dominant. Despite the high accuracy, this approach has a long runtime and requires lots of computing resources, as well as CAD tuned to the analyzed FPGA architecture. Modern FPGA contain more than a million logical gates, therefore, the application of such approach is inefficient. Today, more attention is paid to the development of various models, which allows to evaluate the structure of the routing resources at early stages without using the benchmark circuits. In this work an overview of the existing models and methods for analyzing the structure of FPGA routing resources has been presented. A comparison of the methods and models has been performed, the estimation of their efficiency and possibility of application for designing domestic FPGA has been made. It has been found that the most optimal approach for analyzing of arbitrary structures of the routing resources FPGA is the development and application of mixed methods. This will allow to obtain the accurate models as well as to significantly reduce the development and market entry time.

Published: October 2020

In development of energy converter for feeding the phase rotators and modulators in the system of active phased antenna lattice special requirements to sizes with the specified nominal and peak power of the converter have been presented. In the paper, the concept of manufacturing DC/DC energy converter with reduced weight and size parameters has been presented. It has been proposed to use the switching boards based on aluminitride ceramic with a thermal conductivity of 180–200 W / (m·K). To further reduce the energy losses due to overheating of the components, a digital control system for switching the power switches has been used. A significant reduction in height corresponds to the replacement of a coil transformer with a planar one. The following results can be achieved: an increase of specific power from 2.18 to 3.23 kW / dm3; an increase of peak specific power from 5.66 to 8.4 kW / dm3; a reduction of the height of the experimental sample from 32 to 13 mm; a decrease of volume from 0.115 to 0.0773; an increase of efficiency from 85 to 88.6%.

Reliable, accident-free operation of extra light aviation, drone aircraft, the parachute equipment for landing of people and loads, demands to increase an accuracy of determination of height for the purpose of their safe maneuvering, descent and landing. In the work the critical analysis of existing methods of the height measurement has been carried out for the purpose of defining the most accurate ones and the preference has been given to the barometric method. To decrease the measurement errors, the smart altimeter sensors (SAS) intellectual sensors have been developed, and on their basis the prototype of a barometric altimeter have been designed. In the course of computer modeling and prototyping it has been determined that in designing the altimeter it is necessary to use several SAS, and the accuracy of measurements is essentially affected by an arrangement of sensors on a flying object. The developed method of the height measurement using SAS includes the hardware-software compensation of the errors, caused by the atmospheric phenomena and aerodynamic parameters of the flying object design. The hardware – software for processing the measured data has been developed as well as the software for functioning of intelligent pressure sensor, automatic data processing and the information output to the altimeter display. The tests on the offered technique and hardware – software have been carried out in actual practice of operation. The developed altimeter has been installed on the equipment of a parachutist. In the test result it has been determined that the developed original method and the hardware – software permit to significantly decrease the errors of measurements, which do not exceed 1 meter while the airflow moving at speeds up to 8 meters per second 5 meters up to 70 meters per second
Geometric Modeling of Medical Filtered Back-Projection Images
Authors: Hasan-Zadeh Atefeh
Published: October 2020

This paper deals with the geometric concepts of medical imaging. The main result is proving this novel achievement that the time-frequency projections from some angles in the filtered back-projection image can be calculated by the surface area of the convex body and symplectic Holmes-Thompson volume. For this purpose, the necessary notions are introduced by the surface area of a convex body of the corresponding projective spaces, Radon and Fourier transform in integral geometry, Holmes-Thompson measure in Finsler-Minkowsi-symplectic geometry. This result leads to the other correspondence between basic notions of medical imaging such as the projections from some angles which are equally spaced, the image-frequency of these projections, the low image correctness, and the corresponding notions of Finsler geometry.

Authors: Samifanni Faramarz
Published: October 2020

This article presents a descriptive mixed study regarding the perceptions of university medical-related profession students towards role-playing and their confidence in communication. Students' perception towards role-playing was determined by an open-ended questionnaire while their most important consideration in language study was measured through a seven-point Likert scale. Thematic analysis was used for the qualitative data while descriptive statistics were used to analyze quantitative data. Out of the 144 students from all the classes, 117 medical-related profession students participated in the study. Results showed that role-playing helped the students gain confidence through frequent practice of the target language. Moreover, role-playing showed improvement in the medical-related students’ oral communication skills including their non-verbal communication skills. Furthermore, the students consider practicing the target language as the most important consideration in language study. The results indicate that this study can provide substantial data towards a new approach and a paradigm shift in English language education at the university level; from grammar focused instruction to communicative approach.

Authors: Tran Thi Thuy Linh
Published: October 2020

Using panel data along with the application of Pooled OLS, FEM, and REM estimates, this study conducts an investigation into the effects of a series of factors, namely state ownership, size, tangible assets, growth, return on assets (ROA), effective tax rate, and liquidity, on capital structure of 165 HCMC-based equitized state-owned enterprises (SOEs), categorized into three groups over the 2008–2012 period. As suggested by the findings, tangible assets, ROA, and liquidity are negatively related to leverage ratio and short-term debt ratio for the three groups of enterprises. In terms of firm size, there exists a positive correlation with leverage ratio and short-term debt ratio for Group 1 and 2 but a negative correlation with short-term debt ratio for the case of Group 3.

Authors: Nguyen Thanh Phong
Published: October 2020

Using panel data collected from financial statements of 28 commercial banks in Vietnam, this paper investigates their competitiveness through an analysis of such a few elements as bank size, technological level, human resources quality, and managerial level. For a more objective evaluation the paper employs the Panzar–Rosse (P–R) model along with the use of some common econometrical techniques like Pooled OLS, FEM, REM, GLS, and H-statistic. The results show that the overall competitiveness of these banks is higher, compared to the pre-crisis period of 2008–2009. The monopolistic competition among them are also found, together with certain improvements in bank competitiveness, observed through increased bank size, enhanced human resources quality, better technological advances, and higher levels of managerial skills in compliance with international standards.
Factors affecting green banking practices: Exploratory factor analysis on Vietnamese banks
Authors: Tran Thi Thanh Tu , Nguyen Thi Phuong Dung
Published: October 2020

This paper aims at studying the factors affecting green banking practices in Vietnam and the role of green banking in sustainable development of the Vietnamese economy. A large scale survey con-ducted with 32 banks and financial organizations in Vietnam to obtain 329 questionnaire forms in the period from May to July 2016 provides evidence for the research. By using EFA analysis and the regression model, we find that understanding the definitions of green banking, the current activities of green banking, the advantages in developing green banking, and the focused sectors have positive relationships with the willingness of Vietnamese banks to adopt green banking practices, whereas the barriers have negative relation-ships with the willingness to utilize green banking services among Vietnamese banks. From the research findings, we suggest some solutions to not only enhance the understanding of the importance of green banking in economic development but also improve the willingness to follow green banking practices among Vietnam’s banking institutions.
Determinants of Vietnam’s exports: An application of the gravity model
Authors: Huy Quynh Nguyen
Published: October 2020

The success of exports in Vietnam has become a driving force for economic growth since the reform in 1986. The paper uses data from 2010 to 2014 to estimate the gravity model for Vietnam’s exports with the random effect estimation. The empirical results show that the bilateral trade of Vietnam is positively associated with the country’s GDP and importing countries’ GDP. Furthermore, it has a negative relationship with distance from Vietnam to trading partners. These results are akin to those of the previous studies of the gravity model. Particularly, foreign direct investment, border effects and exchange rate play a significant role in promoting exports of Vietnam. Besides, the deepened integration into the region and world market also has significant impacts on expanding exports of Vietnam. Therefore, these factors have contributed to explaining the success in exports of Vietnam over the past few years.

A note on adaptivity in factorized approximate inverse preconditioning
Authors: Kopal Jiří , Rozložník Miroslav , Tůma Miroslav
Published: October 2020

The problem of solving large-scale systems of linear algebraic equations arises in a wide range of applications. In many cases the preconditioned iterative method is a method of choice. This paper deals with the approximate inverse preconditioning AINV/SAINV based on the incomplete generalized Gram–Schmidt process. This type of the approximate inverse preconditioning has been repeatedly used for matrix diagonalization in computation of electronic structures but approximating inverses is of an interest in parallel computations in general. Our approach uses adaptive dropping of the matrix entries with the control based on the computed intermediate quantities. Strategy has been introduced as a way to solve di cult application problems and it is motivated by recent theoretical results on the loss of orthogonality in the generalized Gram– Schmidt process. Nevertheless, there are more aspects of the approach that need to be better understood. The diagonal pivoting based on a rough estimation of condition numbers of leading principal submatrices can sometimes provide inefficient preconditioners. This short study proposes another type of pivoting, namely the pivoting that exploits incremental condition estimation based on monitoring both direct and inverse factors of the approximate factorization. Such pivoting remains rather cheap and it can provide in many cases more reliable preconditioner. Numerical examples from real-world problems, small enough to enable a full analysis, are used to illustrate the potential gains of the new approach.

The impact of ACE inhibitors on the risk of SARS-CoV-2 virus infection and the course of COVID-19 disease
Authors: Plech Tomasz
Published: October 2020

Invasion of SARS-CoV-2 virus into human cells is mediated by the interaction of viral particles with a specific protein – angiotensin-converting enzyme 2 (ACE-2). Due to the involvement of ACE-2 in blood pressure regulation, there have appeared reports of possible negative effects of taking some cardiological drugs during coronavirus pandemic. Some hypotheses suggest an increased risk of SARS-CoV-2 infection and more severe clinical course of COVID-19 in patients treated with angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers. In the face of contradictory information regarding this question, several societies of cardiology and hypertension have issued clinical recommendations for patients treated with the above-mentioned drugs. These recommendations conclude that there are no unambiguous data that would support the hypothesis about the negative effects of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers on patients infected with SARS-CoV-2 virus. Therefore, it is highly recommended not to discontinue treatment in patients in whom these drugs lead to improvement in their clinical condition.

Authors: Komkina T.A. , Nikonova M.A. , Dubinina M.G.
Published: October 2020

Subject. The article analyzes development trends in certain types of service robots, namely, hybrid UAVs, bionic prosthetic hands, robotic vacuum cleaners.
Objectives. We focus on identifying the main trends in the development of certain types of service robots, building dynamic models of their technical indicators and models of dependence of their price and weight on absolute characteristics and technical parameters.
Methods. The study employs methods of correlation and multiple regression analysis. The data of the IFR, the Remotely Piloted Aircraft System, and websites of robot manufacturers serve as the informational basis of the paper.
Results. The modeling unveils positive correlation between the integrated indicator of the technical level of hybrid UAVs of convertiplane type and the wingspan. The analysis of modern bionic prosthetic hands shows that the developers focus on optimizing the structure of the prosthetic, however, as the functions of the hand improve, the weight of bionic hand increases. The main factors influencing the price of robot vacuum cleaners are their power, weight, and operating hours.
Conclusions. The unit price of a complex indicator of the technical level of hybrid UAVs is lower than the corresponding indicator of fixed-wing UAVs, reflecting a greater efficiency of hybrid UAVs. The analysis of technical indicators of robotic prosthetics (using the case of bionic hands) shows that any improvement of functional characteristics leads to deterioration of weight. The analysis of technical and economic indicators of robotic vacuum cleaners reveals a positive correlation between the price and weight, operating hours and power.
Regional inequality by the Theil index
Authors: Moroshkina M.V.
Published: October 2020

Subject. Regions are different across Russia in terms of most social and economic indicators. There is the regional inequality of economic and social indicators. The Russian regions demonstrate a serious gap in terms of the productive sector development, since the industrial and productive potential is unevenly allocated across regions.
Objectives. The study mainly analyzes the dynamics of the regions’ economic development, which is measured by GRP per capita and industry. I also determine what caused regional disparities within 1990 through 2017. Thus, I examine the Russian regions and focus on the level of cross-regional differentiation of the reproductive potential.
Methods. Examining the cross-regional difference, I sufficiently apply techniques for evaluating the regional inequality. As part of the study, I use the Theil index to measure the difference within a group and of groups. The study will not only reveal and analyze the extent of cross-regional differentiation, but also observe how the inflation influence the dynamics of regional difference of the Russian regions.
Results. As part of the analysis of trends in the Theil index, the Russian regions were observed to have different GRP per capita and goods shipped. The findings signify a growth in the regional inequality.
Conclusions and Relevance. The Russian regions are showed to fall into a greater disparity when oil prices grow. This may be possible due to a reduction in the State financial aid to lagging regions. As the regional differences were found to tend to grow, I can admit the divergence of the Russian regions. The findings can be used to create strategic documents, local and regional development programs.

Design and Manufacture of 6 Axis Force and Moments Transducers for Seaplane Floaters Test in Towing Tank
Authors: Nurhadi Nurhadi , Nasir Mochammad , Permana Chandra , Suwarni Endah
Published: October 2020

To develop seaplanes as a means of inter-island transportation, it is necessary to have a simulation, testing, and analysis of force measurements that work so that the aircraft can be designed optimally in terms of function and safety.

To fulfill one type of test, the seaplane floater model is pulled in the Towing Tank to determine the hydrodynamic forces acting on the floater which include resistance (Fx), side force (Fy), lift force (Fz), and moments in all three axes. A method of measuring the force of 6 axis force and moment or 6 degrees of freedom (6 Degree of Freedom, 6 DOF) was built and designed by combining several single load cells so that these forces can be known optimally.

From the results of the 6 DOF transducer design, it is proven that it can be used well in measuring 6 forces and moments with force measurement errors ranging from 1.38%. The distance between the 6 DOF transducer capture point and the floater force capture point will affect the measured moment transformation.

Objective: To evaluate the relationship between metabolic syndrome (MS) and oral health. Methods: This is a bibliographic review with articles available in the PubMed, SciELO, Web of Science, Google Scholar and Portal Periódicos databases, published between 2010 and 2020. The keywords used were metabolic syndrome, oral health, obesity, diabetes, hypertension, periodontitis and caries. Results: MS and oral pathologies are some of the biggest health problems in the world today and tend to increase with the development of countries and with the aging of the population. The literature indicates a close relationship between MS and oral health, mainly associating diabetes mellitus (DM) and periodontitis, obesity and dental caries, cardiovascular disease, and periodontitis. Inflammatory factors and diet are important mediators of these relationships. Conclusion: MS and oral health are associated through the mechanisms of inflammation, the immune system, and the diet. MS can reciprocally aggravate dental caries and periodontitis, as well as oral treatment can assist in the treatment of MS, but there are still controversial results and this relationship should be further clarified.
Online formative assessment coupled with synchronous online learning: Insight from an Indian medical college
Authors: Mondal Himel , Mondal Shaikat
Published: October 2020

Objectives:

During the coronavirus disease-19 pandemic, majority of the institutions have started distance education. Assessments are also being conducted online. Our question was about the interest of students in assessing their classroom learning by an online quiz. The aim of this study was to observe students’ participation pattern in online anonymous formative assessment immediately after synchronous 1-h online class.

Material and Methods:

We designed online quizzes with five questions related to the preceding class. In the last quarter of the 1-h class, we shared the quiz with the students. A total of 20 such classes were conducted. We recorded anonymous data on attendance, participation, time of participation, and obtained marks. The data were expressed in mean, standard deviation (SD), and percentage. Chi-square test, t-test, and ANOVA were used according to the data.

Results:

Among 100 1st-year medical students, average attendance in online classes (62.1 ± 13.5) was lower than the face-to-face 1-h lecture class (80.35 ± 13.01, t-test P < 0.001). Average 55.48% (34.45 ± 7.13) of the attendee participated in the online formative assessment. Approximately, students took 4¼ min to answer the online quiz (minimum 45, median 204, maximum 988, mean 255.76, and SD 154.96 sec). The quiz score was high among the students with 46.73% of the quiz participants scoring full marks.

Conclusion:

Nearly half of the students attending online classes opted for an anonymous, optional, and online self-assessment quiz. The online quiz is a quick method of formative assessment requiring only few minutes. Further, research should be conducted to find ways to increase participation among the students.

Paraneoplastic pemphigus is an autoimmune blistering disease associated with an underlying malignancy. This is a case of a 13-year-old boy initially presenting with isolated oral erosions – managed as a case of pemphigus, who one and a half years later developed toxic epidermal necrolysis like rash, both refractory to treatment. Evaluation for an underlying malignancy revealed a retroperitoneal Castleman’s tumor, following the excision of which there was clinical remission of the oral and skin lesions.
Clara Schumann and Jenny Lind in 1850
Authors: Kim Ji Young
Published: October 2020

Clara Schumann’s 1850 tour of northern Germany with her husband officially ended with a successful concert in Altona where Jenny Lind made a surprise appearance. Immediately thereafter, one more concert featuring the pianist, singer, and Robert’s music was added at the last minute to take place in Hamburg. This too was a success. But a detail that made it especially memorable was Lind’s position behind the piano lid so that, as Clara recounted in her diary, many audience members could hardly catch a glimpse of her. This paper explores the rationales and implications of this singular and fleeting moment, and teases out aspects of the two star performers’ relationship both on and off the stage. In the process, the paper draws attention to hitherto neglected variables in the performance practice of Lieder and seeks to expand our lines of inquiry with regards to the 19th-century Lied as cultural practice.

Nowadays, aggregation-induced emission luminogens (AIEgens) with reactive oxygen species (ROS) generating ability have been used as photosensitizers for imaging guided photodynamic therapy (PDT). To achieve enhanced antitumor outcomes, combining AIEgens-based PDT with chemotherapy is an efficient strategy. However, the therapeutic efficiency is hampered by the limited cellular uptake efficiency and the appropriate light irradiation occasion. In this paper, a self-guiding polymeric micelle (TB@PMPT) composed of two AIE photosensitizers and a reduction-sensitive paclitaxel prodrug (PTX-SS-N3) was established for enhanced chemo-photodynamic therapy by a dual-stage light irradiation strategy. When the micelles were accumulated in tumor tissues, the first light irradiation (L1, 6 min) was utilized to facilitate cellular uptake by “photochemical internalization” (PCI). Then the intracellular glutathione (GSH) would induce the PTX release, micelles disassembly and the aggregation state change of AIEgens. The fluorescence signal change of two AIEgens-based ratiometric fluorescent probe could not only precisely guide the second light irradiation (L2, 18 min) for sufficient ROS production, but also monitor the non-fluorescent drug PTX release in turn. Both in vivo and in vitro studies demonstrated that the dual-stage light irradiation strategy employed for TB@PMPT micelles exhibited superior therapeutic effect than only 24-min continuous light irradiation.
The Dynamics of Foreign Language Values in Sweden: A Social History
Authors: Gheitasi Parvin , Lindgren Eva , Enever Janet
Published: October 2020

This paper gives an account of the history of foreign language values in Sweden from the seventeenth century to the present. The paper is informed by sociocultural standpoints on language and language learning according to which language is a dynamic tool that is appropriated by individuals to achieve particular purposes, and that dialogically creates and renews our social world(s).  Since the sixteenth century, three languages (German, French and English) have been taught in Sweden as foreign languages during particular eras. In this paper, we explore how language value can be understood as a system that evolves over time as a result of triggers such as power, trade and personal benefits. The impact of these variables on Swedish society’s efforts to invest in learning a particular language during specific eras is critically examined from the perspectives of nested systems.

Studies based on the use of an electronic microscope revealed ultrastructural changes in plant cells of lettuce and Basil in interaction with Ps.aeruginosa ATCC B3994, expressed in deformation and violation of the integrity of the cell wall, increasing the size of chloroplasts, sometimes full destruction accompanied by the increased number of plastoglobuli. Ps.fluorescens ATСC948 were localized in the cytoplasm and chloroplasts of cells without a cytotoxic action. Plant isolates were identified with gram staining, biochemical tests and PCR. Contamination of non-heattreated leaf vegetables with virulent strain Ps. aeruginosa is a potential threat to human health and life.

Published: October 2020

Background: Interstitial lung diseases (ILD) comprise a diverse group of heterogeneous entities. Epidemiology, clinical profile and prognosis of interstitial lung diseases widely vary globally. Little data are available on ILD in Sri Lanka. Objective and methodology: A single center descriptive study conducted at Teaching hospital-Kandy, Sri Lanka among diagnosed ILD patients from 2007-2018. Demographic, clinical and radiological data were collected retrospectively to analyse clinical profile, aetiology, classification and outcome of interstitial lung diseases. Results: 302 subjects were analyzed (mean age 59.5 years, female 61.3%). Idiopathic interstitial pneumonias (IIP) were the commonest (42.3%, N=128) followed by secondary ILD due to known aetiologies(40.7%, N=123), hypersensitivity pneumonitis (14.6%, N=44) and sarcoidosis (2%, N=6). Majority of IIPs were nonspecific interstitial pneumonia (NSIP)(46.8%, N=60), followed by idiopathic pulmonary fibrosis (IPF)(28.1%, N=36). Majority of secondary ILDs were due to connective tissue diseases (87%, N= 107). Shortness of breath and cough were the commonest presenting symptoms, found in 271 (90.3%) and 250 (83.3%) patients respectively. High resolutions computerized tomography (HRCT) was performed in all, but histology was available in 54 (17.8%). Lung functions tests (LFT) were normal in 71 (26.3%), but demonstrated restrictive pattern in 182 (67.4%). Mean percentage predicated forced vital capacity (FVC) was 66.91 ± 18.7% while mean percentage predicted forced expiratory volume at 01 second (FEV1) was 69.92 ± 20.0%. Therewas no significant change in LFT during follow up. Infective exacerbations needing hospitalization was the commonest complication seen in 86 (40.3%). Data on follow up radiological investigations were noted in 143 (47.5%), in which 59 (41.2%) demonstrated radiological improvement, while 34 (23.7%) had progressive changes and 50 (34.9%) had HRCT changes similar to previous images. 184 patients were found surviving, while 43 were dead.  Higher mean age, male gender, current or previous smoking, lower distance achieved at 6-minute walking test, or any history of hospitalizations due to infective exacerbations were noted to be associated significantly in patients with mortality. Conclusion: IIP and secondary ILDs were similar in prevalence in the cohort of diagnosed ILD patients from central Sri Lanka. Idiopathic NSIP outnumbered IPF in the sample.
