Abstract. Taberima S, Prabawardani S, Sarwom R, Lyons G. 2020. Organic fertilizer applications improve the growth of vegetable crops and chemical properties in the tailings deposition area at Timika, Papua, Indonesia. Nusantara Bioscience 12: 134-142. This study aimed to observe growth responses of selected vegetable crops grown in the media of inactive tailings, the available nutrients (macro and microelements) in fresh tailings before and after planting, as well as the metal uptake by plant tissues. Research was conducted using Randomized Block Design with three treatments of organic matter (chicken manure, cow manure, and compost of Salvinia natans) to observe the response on growth and yield of kangkong, red spinach, tomato, and chili. Based on the geochemical data, the ratio of ANC/MPA ranged from 3.81 (0-20 cm) to 4.60 (20-40 cm). There was no acid potential, with ANC ratio > 1.5 x MPA, and this result was supported by soil pH, which was alkaline in both depths of tailings media, ranging from 7.94 (0-20 cm) to 7.90 (20-40 cm). There was no significant effect on the chemical properties in the first period before and after planting for three months of planting period, except for the application with organic fertilizers. The best organic fertilizers applied in fresh tailings were chicken manure, followed by the compost of S. natans and cow manure. These organic fertilizers produced good growth and yield components of kangkong, red spinach, tomato, and chili. Meanwhile, the lowest growth and yield response of these crops was shown by control (without compost or manure). The level of metal uptake by all vegetables was low, suggesting that these vegetables are safe to be consumed.

Abstract. Akbari M, Rafinejad J, Hanafi-Bojd AA, Aivazi AA, Biglarian A, Sheikhi S, Shavali Z, Akbarzadeh K. 2020. Human myiasis survey in Ilam Province, Southwest of Iran. Nusantara Bioscience 12: 143-147. Myiasis is the infestation of live human and vertebrate animals with dipterous larvae, which at least for a period. Ilam Province of Iran is one of the most important animal husbandry areas, especially nomadic, in Iran. The objective of this study was to identify the prevalence of myiasis in shepherds in Ilam Province. A cross-sectional study was conducted among the shepherds in Ilam Province, western Iran. Out of the 11 counties in Ilam Province, 6 were randomly chosen from three different climates for this study. A questionnaire was used by a trained interviewer to obtain the information from subjects. The disease has been seen in spring, summer, and autumn seasons. About 94.1% of people have been infested at least once. Pharyngeal myiasis had the highest prevalence with 58.3%. Itchy, painful throat, sneeze, cough, and headache were common symptoms. About 85.1% of people described the symptoms of the disease as severe and very severe. About 75.4% stated that the duration of the disease was more than 5 days. According to the results of the study, it was found that the prevalence of myiasis among shepherds in the Ilam Province is high and it is necessary to take appropriate measures to control the disease and increase health literacy.
Rising powers and the Gulf Monarchies during the COVID-19 Pandemic
Authors: Burton Guy
Published: October 2020

How are rising powers like Russia, India and China responding to the pandemic among the Gulf monarchies and what are the implications for rising power behaviour more generally? Through an examination of these powers’ established relations with the Gulf monarchies and the impact of the COVID-19 pandemic on the regional energy and labour markets and the search for a vaccine, the article highlights the opportunities and constraints faced by each. The variety of approaches taken by rising powers in a volatile environment (like today’s Middle East) challenges the assumption that they will adopt a singular strategy in relation to the international system, either as a supporter, spoiler or shirker in an international system. But this may change as the system becomes more settled.

Published: October 2020

In this paper, we propose a broadband omnidirectional near-perfect absorber that transforms light energy into heat. In contrast to previous research on structural metamaterials, this study focuses on light absorption in the epsilon-near-zero (ENZ) layers without any structural patterns. Chromium (Cr) thin films were applied as ENZ layers. Using the admittance method, we found the proper thicknesses of

Enhanced melting flow and vaporization model and its applications in pulsed laser polishing on mold steel
Authors: Lu Yao , Sun Zhiqiang , Yang Lijun , Wang Maolu , Wang Yang
Published: October 2020

A developed three-dimensional finite element model to describe surface profiles and root mean square (RMS) roughness by pulsed laser polishing based on the melting flow and vaporization removal mechanism is innovatively presented. In this paper, we indicate that the melting flow and vaporization removal are the primary mechanisms in the laser polishing process and successfully simulated the S316 mold steel pulsed laser polishing via the finite element method. Notably, vaporization removal, vaporization expansion, and plasma impact pressure, which is based on the Navier–Stokes equation, continuity equation, and Marangoni effects, are crucial factors, which are creatively taken into account in this model. Besides, due to the physical parameters changing with temperature, it is critical to considering the temperature-dependent density, specific heat capacity, thermal conductivity coefficient, dynamic viscosity, and tension coefficient to make the simulation results and model accurately. In addition, the tailored model can predict the theoretical polishing surface profiles and RMS roughness based on the melting flow and vaporization removal mechanism. Regarding the single pulse laser polishing, we investigated the surface profiles and RMS roughness on different single pulse energy and pulse width. In summary, it is expected that this study could provide a theoretical reference regarding the laser polishing metals and pave the way for laser manufacturing in various industrial applications.
Simplified system for relative phase control between two input beams for coherent polarization beam combination
Authors: Sakakibara Rei , Mio Norikatsu
Published: October 2020

We devised a simplified system for coherent polarization beam combination (CPBC), in which two beams with orthogonal polarizations are combined with a polarizing beam splitter (PBS). In a CPBC system, control of the relative phase between two beams is important to obtain an output beam with stable polarization. Herein, the beam leaked from PBS is used to control the relative phase, realizing a robust system. We experimentally demonstrate that the proposed system can be operated with high efficiency and without quality deterioration.

Quantification of plant morphology and leaf thickness with optical
coherence tomography
Authors: de Wit Jos , Tonn Sebastian , Van den Ackerveken Guido , Kalkman Jeroen
Published: October 2020

Optical coherence tomography (OCT) can be a valuable imaging tool for
in vivo and label-free digital plant phenotyping. However, for imaging
leaves, air-filled cavities limit the penetration depth and reduce the
image quality. Moreover, up to now quantification of leaf morphology
with OCT has been done in one-dimensional or two-dimensional images
only, and has often been limited to relative measurements. In this
paper, we demonstrate a significant increase in OCT imaging depth and
image quality by infiltrating the leaf air spaces with water. In the
obtained high-quality OCT images the top and bottom surface of the
leaf are digitally segmented. Moreover, high-quality en face images of
the leaf are obtained from numerically flattened leaves. Segmentation
in three-dimensional OCT images is used to quantify the spatially
resolved leaf thickness. Based on a segmented leaf image, the
refractive index of an infiltrated leaf is measured to be , deviating only 1.2% from that of
pure water. Using the refractive index and a correction for refraction
effects at the air-leaf interface, we quantitatively mapped the leaf
thickness. The results show that OCT is an efficient and promising
technique for quantitative phenotyping on leaf and tissue level.
Amplification of optical activity in a fiber loop resonator
Authors: Alexeyev C. N. , Barshak E. V. , Lapin B. P. , Vikulin D. V. , Yavorsky M. A.
Published: October 2020

In this paper, we have theoretically studied an effective amplification
of optical activity by a fiber loop resonator. We propose a scheme in
which an optically active element is placed in the loop segment of the
resonator. Assuming that the coupling in the resonator is
polarization-independent, we have shown that initially small
polarization plane rotation, which arises due to the optically active
element, can be significantly amplified by tuning the resonator’s
closed-path phase. We have also studied the influence of losses on the
amplification of optical activity. We have shown that the maximal
amplification takes place under the condition of critical coupling, at
which the attenuation parameter is equal to the resonator’s effective
reflection coefficient. We have also studied effective dichroism in
such a system and shown the relevance of a critical coupling regime to
that effect.
Relative retinal flow velocity detection using optical coherence tomography angiography imaging
Authors: Richter Dmitry , Fard Ali M. , Straub Jochen , Wei Wei , Zhang Qinqin , Wang Ruikang K.
Published: October 2020

Optical coherence tomography angiography (OCTA) imaging is a valuable tool for the visualization of retinal vasculature at an unprecedented level of details. However, due to relatively long time-interval between repeated scans in the conventional OCTA scanning protocol, the OCTA flow signal suffers from low dynamic range and loss of velocity-intensity correlation. The ability to distinguish fast and slow flow in the retina may provide a powerful tool for the assessment of early-stage retinal diseases such as vein occlusion. Here, we report a method to detect relative flow velocity in human retina using a 67.5 kHz spectral-domain OCTA device. By adapting the selection of A-scan time-intervals within a single OCTA acquisition and combining the resulting OCTA images, we expand the detectable velocity range. After a quantitative validation of this method performing microchannel flow experiments with varying flow velocities, we demonstrate this approach on human eyes using CIRRUS HD-OCT 5000 with AngioPlex (ZEISS, Dublin, CA) through a prototype scanning pattern.
Passive optical heterodyne spectroscopy measurement of the Doppler shift of Fe(I) lines induced by the rotational velocity of the Sun
Authors: Sappey Andrew D. , Masterson Pat , Sappey Ben A.
Published: October 2020

We have developed a sensitive, novel laser heterodyne radiometer using a fiber-coupled distributed feedback laser as the local oscillator to measure Fe(I) Fraunhofer lines Doppler-shifted by the rotational motion of the Sun. The radiometer repetitively measures the Doppler shift of an Fe(I) Fraunhofer line at a vacuum wavelength of 1559.252 nm induced by the Sun’s rotation on its eastern and western limbs. The measured shift is slightly smaller than expected as a result of the simple solar tracking system and collection optics used for demonstration. We show through calculation that a multichannel instrument of identical design in conjunction with a Keck-class telescope can be used to search for exoplanets in nearby star systems using the star-wobble radial velocity method with

Authors: Brizard Benoit , Leblanc Adrien , Petit Stéphane , Delagnes Jean-Christophe , Cormier Éric , Ibrahim Heide , Légaré François , Lassonde Philippe
Published: October 2020

The frequency-resolved optical switching (FROSt) method developed for ultrashort pulse characterization is implemented for single-shot measurements. In this basic demonstration, the delay axis of the spectrogram is spatially encoded by the pump beam having a small incident angle with the photoexcited material. We present the calibration procedure for spectrograms acquired in single-shot and the temporal characterization of 44 fs pulses with central wavelength at 800 nm both in scanning and single-shot FROSt configurations. The retrieved pulses are compared by means of the root-mean-square field error. Finally, the pulses are propagated through a known dispersive material to measure the added group-delay dispersion.
Bacteriological and molecular study of Salmonella species associated with central nervous system manifestation in chicken flocks
Authors: Badr Heba , Soliman Mohamed A. , Nasef Soad A.
Published: October 2020

Background and Aim: Salmonella species often cause systemic health problems in poultry flocks, sometimes including nervous systems manifestations. This impact of Salmonella has rarely been studied. This study aimed to define an alternative pathogenic pathway for Salmonella spp. invasion of brain tissue in chicken flocks. Brain infection produces neurological manifestations; Salmonella strains isolated from brain tissue showed the presences of two virulence genes. Confirmation of the pathway of isolates from intestinal mucosa through the blood–brain barrier was attained using experimental infections in specific pathogen-free (SPF)-day-old chicks through two routes of inoculation. Materials and Methods: Isolation of Salmonella spp. from five chicken flocks that showed signs of the central nervous system (CNS) effects were isolated. Isolates were characterized by serotyping, and antimicrobial assays. In addition, virulence profiles were described using detection of virulence plasmid spvC, and Salmonella plasmid sopB. A pathogenicity study of isolates in specific pathogen-free (SPF)-day-old chicks through oral and intracerebral administration performed, and experimental infection in SPF embryonated chicken eggs through intra-yolk and intra-allantoic administration was investigated. Supporting histopathology and immunohistopathology against Salmonella antigen in brain tissue were performed for flock and experimental infections. Results: Three serotypes of Salmonella were isolated from the brains of five flocks (two Salmonella Virchow, two Salmonella Kentucky, and one Salmonella Enteritidis isolates). Phage related gene sopB and plasmid-mediated operon spvC were identified in all isolated strains. The Salmonella strains were re-isolated and identified from the brain and internal organs of post-experimental infected chicks. Infected chicks showed nervous manifestations associated with Salmonella infection. The presence of positively stained Salmonella antigen in brain tissues indicates penetration of the blood–brain barrier by the Salmonella species. Conclusion: Our results indicate that some virulent systemic strains of Salmonella spp. can induce CNS manifestations in chicken hosts.

Introduction to Thinking the Problematic: Decentring as Method and Ethos
Authors: Leistert Oliver , Schrickel Isabell
Published: October 2020

The contribution sketches the most important lines of thought that have contributed to a positive conception of problems. By way of introducing the contributions to the volume, we contextualize the different strands of epistemological and ontological takes on what has been called »the problematic«. Most importantly we foreground a genealogy of thinking that rejects operational separations between the thinking subject and the object of thought and thus foreground a key epistemological trick of modernity in the construction of unbound objectivity. In the course of this preliminary reconstruction, we visit historical sites of institutional crisis and scientific reason during the second half of the 20th century that signify the shattered imaginaries of the problem-solution equation, which continues to haunt scientific mindsets up until today. The problematic, as a figure of habitation, is reconstructed along the lines of 20th century French thought, as much as along feminist critiques of unbound objectivity expressed with concepts such as situated knowledges. It turns out that the problematic is a key figure in the development of an epistemic ethos that can be constructed from a diversity of strands of thought, like pragmatism, speculative philosophy, or Deleuzian dramatisation.
On the Temptations of Comfort
Authors: Sezer Burak
Published: October 2020

This paper investigates the relationship between the concepts of comfort and sloth. While we intuitively assume a proportional correspondence between the two - more comfort results in more sloth and vice versa - I draw on the writings of American author Thomas Pynchon to elucidate why such a straightforward conclusion fails. In fact, Pynchon points to many possible modes of sloth in different cultural contexts, which I label »Writerly Sloth«, »Readerly Sloth«, »Watcherly Sloth«, and »Laugherly Sloth«, that all individually bring about a characteristic form of comfort and discomfort. Following Pynchon's concise overview of the historical ramifications of the philosophy of sloth since Thomas Aquinus, I attempt to connect the poetics of slothfulness with specific events of US-American literature and politics from within their respective zeitgeists, such as the refusal to work during the heyday of Wall Street capitalism or watching TV in California in the 1960s.
"A sort of strange beginning out of time"
Authors: Carandina Elisa
Published: October 2020

The chapter explores a new notion of comfort with respect to repetition and memory. This new approach is based on a definition of comfort as an involuntary cultural memory. In the first sections, this new perspective about comfort is fully developed regarding its repetition dynamic with respect to both personal and cultural memory. Focusing then on the literary implications of this definition, the dynamic of comfort defined as such is used in relation to narrative forms. More precisely, comfort as involuntary cultural memory is contextualized with reference to Leah Goldberg's Diary leading to an exploration of comfort and the narrativization of the self. The »sort of strange beginning out of time« that defines Goldberg's experience in the pages of her diary is also developed with reference to the poetic version of these days. Comfort, as involuntary cultural memory, describes then a personal and literary attempt to escape time, to bring back the possibility of a past and of a future that are both lost, to flee reality and time. However, reality and time keep coming back, and the only achieved flight is the one towards the self.

Inklusion, das Politische und die Gesellschaft
Authors: Geldner Jens
Published: October 2020

Ideologievorwurf, Ressourcen-Etikettierungs-Dilemma, exkludierende pädagogische Praxen - die Hoffnungen inklusiver Pädagogik scheinen weitgehend enttäuscht. Es gilt daher auszuloten, ob und wie ein bildungspolitisches Projekt der Inklusion noch einen Beitrag zur Demokratisierung des Bildungssystems leisten kann. Was kann es heißen, die Debatten um Inklusion zu (re-)politisieren? Was, sie gesellschaftstheoretisch zu fundieren? Mithilfe radikaler Demokratietheorien zeigt Jens Geldner, dass es sich hier wie dort von Essentialismen und diskursiven Schließungen dessen zu lösen gilt, was Inklusion sein soll. Was bleibt, ist ein Einsatz für die Anerkennung der Kontingenz und Umstrittenheit pädagogischer Ordnungen.

Marcel Duchamp und die Alten Meister
Authors: Bethlen Patricia
Published: October 2020

Marcel Duchamp ist nicht nur als radikaler Neuerer und im Bruch mit Traditionen stehend zu denken. Patricia Bethlens wissenschaftliche Auseinandersetzung mit seinem Œuvre geht erstmals einen neuen Interpretationsweg und analysiert sein Schaffen unter dem Blickwinkel der Vorbildnahme altmeisterlicher Kunst. Inspirationsmomente, Ideen-Modelle, Werkinhalte, Transformationen und wiederkehrende Themen der Kunst können unter dem neuen Fokus der Alten Kunst nachvollzogen werden und versprechen eine innovative Sicht auf das Hauptwerk »Großes Glas« und das Spätwerk »Étant donnés«. Nicht ohne Humor baut Duchamp auf den Werken vorangegangener Genies wie Albrecht Dürer oder Leonardo da Vinci auf, die er imaginär als seine selbst gewählte künstlerische »Verwandtschaft« begreift.
Fragile kollektive Identitäten
Authors: Wilk Martin
Published: October 2020

Warum radikalisieren sich politische Akteur*innen? Die Antworten darauf sind vielschichtig und werden nicht selten kontrovers diskutiert. Martin Wilk nutzt neuere Ansätze der Bewegungsforschung, um dieser Frage am Beispiel des US-amerikanischen »Student Nonviolent Coordinating Committee« (SNCC) nachzugehen, das sich im Laufe der 1960er Jahre von einer gewaltfreien zu einer gewaltbereiten Organisation wandelte. Er zeigt auf, dass insbesondere Ansätze, die sich mit der Konstruktion kollektiver Identitäten in sozialen Bewegungen beschäftigt haben, eine wertvolle Erweiterung unseres Verständnisses von Radikalisierungsprozessen bieten.
Gênero e meio ambiente em estudo de revisão da pesquisa social sobre desigualdade socio-ambiental no Brasil
Authors: Mortale Talita , Moreira Sueli , Neiman Zysman
Published: October 2020

O debate sobre gênero e meio ambiente é uma das premissas do Desenvolvimento Sustentável para alcançar a redução da desigualdade social. Portanto, o presente estudo se propõe a revisar a literatura em busca de estudos sobre gênero e meio ambiente, com impactos nos direitos sociais de mulheres. Os dados foram obtidos através de abordagem metodológica teórico-conceitual, com revisão da literatura dos últimos 10 anos focados em pesquisa social de natureza qualitativa. A análise e interpretação dos dados se deram a partir da busca de categorias expressivas dos artigos. Os resultados demonstraram que a historicidade marcada pelo patriarcado e sistema político econômico capitalista têm reforçado os padrões de desigualdade entre os gêneros. Natureza como fonte inesgotável de recursos, meio de vida e subsistência. Em conclusão, apesar da importância dos estudos qualitativos em registrar a diversidade no cotidiano feminino, são necessários estudos de intervenção para instrumentalizar a autonomia e emancipação de mulheres no campo, para assegurar o acesso ao meio ambiente sob a perspectiva do desenvolvimento sustentável.

Authors: Kumar Jitender , Singh Harpreet , Raj V. Bhasker , Nimal A. T. , Gupta Vinay , Singh Vinay Kumar
Published: October 2020

Nerve agents are often used at the military warfront, where diesel is a very common interferant. In the present work, a group of surface acoustic wave (SAW) sensors, called E-Nose with dissimilar sensing layers is developed for the recognition of the mixture of diesel and dimethyl methylphosphonate (DMMP) vapors. The exposure of DMMP and diesel vapors is kept at ppb and ppm levels respectively. Varied response patterns of DMMP and diesel vapors were obtained by SAW E-nose. Principal component analysis (PCA) has been used to extract features from the response curves of SAW sensors. Artificial Neural Network pattern recognition has been implemented to identify the precise detection of DMMP vapors in the binary mixture of DMMP and diesel. The effect of pre-processing (using PCA) the raw data before feeding it to artificial neural network is also studied.

Authors: Mahala V. K. , Sahani R. M. , Vaijapurkar S. G.
Published: October 2020

CaSO4:Eu phosphor is synthesised by acid distillation method with varying synthesis parameters for studying its Radiophotoluminescence (RPL) properties for gamma absorbed dose measurements. Five phosphor samples are prepared by varying quantity of solvent, distillation temperature and reaction time. XRD, SEM, particle size analysis and photoluminescence studies are carried out. The characterisation study shows polycrystalline luminescent particles of average size varying from 35 μm to 55 μm. Characteristic emission of Eu3+ is observed around 590, 615 and 620 nm at 242 nm excitation. Gamma dose response of maximum Eu3+ PL intensity sample is studied in the range 10 cGy to 1000 cGy using Co-60 source. Gamma radiation exposure induces conversion of Eu3+ to Eu2+ giving luminescence at 385 nm with 320 nm excitation. Repetitive measurements of gamma exposed samples are carried out and no significant fading is observed within one week of post-irradiation. The phosphor has the potential to be used for gamma dosimetry.

Authors: Dagogo-George Tamunopriye Ene , Mojeed Hammed Adeleye , Balogun Abdulateef Oluwagbemiga , Mabayoje Modinat Abolore , Salihu Shakirat Aderonke
Published: October 2020

Diabetic Retinopathy (DR) is a condition that emerges from prolonged diabetes, causing severe damages to the eyes. Early diagnosis of this disease is highly imperative as late diagnosis may be fatal. Existing studies employed machine learning approaches with Support Vector Machines (SVM) having the highest performance on most analyses and Decision Trees (DT) having the lowest. However, SVM has been known to suffer from parameter and kernel selection problems, which undermine its predictive capability. Hence, this study presents homogenous ensemble classification methods with DT as the base classifier to optimize predictive performance. Boosting and Bagging ensemble methods with feature selection were employed, and experiments were carried out using Python Scikit Learn libraries on DR datasets extracted from UCI Machine Learning repository. Experimental results showed that Bagged and Boosted DT were better than SVM. Specifically, Bagged DT performed best with accuracy 65.38 %, f-score 0.664, and AUC 0.731, followed by Boosted DT with accuracy 65.42 %, f-score 0.655, and AUC 0.724 when compared to SVM (accuracy 65.16 %, f-score 0.652, and AUC 0.721). These results indicate that DT's predictive performance can be optimized by employing the homogeneous ensemble methods to outperform SVM in predicting DR.

Authors: Zhao Zhingtang , Wu Qingtao
Published: October 2020

In intelligent computer-aided video abnormal behavior recognition, pedestrian behavior analysis technology can detect and handle abnormal behaviors in time, which has great practical value in ensuring social safety. We analyze a deep learning video behavior recognition network that has advantages in current research. The network first sparsely sampled the input video to obtain the video frame of each video segment, and then used a two-dimensional convolutional network to extract the characteristics of each video frame, then used a three-dimensional network to fuse them. The method realizes the recognition of long-term and short-term actions in the video at the same time. In order to overcome the shortcoming of the large amount of calculation in the 3D convolution part of the network, this paper proposes an improvement to this module in the network, and proposes a mobile 3D convolution network structure. Aiming at the problem of low utilization of long-term motion features in video sequences, this paper constructs a deep residual module by introducing long and short-term memory networks, residual connection design, etc., to fully and effectively utilize the long-term dynamic features in video sequences. Aiming at the problem of large differences in similar actions and small differences between classes in abnormal behavior videos, this paper proposes a 2CSoftmax function based on double center loss to optimize the network model, which is beneficial to maximize the distance between classes and minimize the distance between classes, so as to realize the classification and recognition of similar actions and improve the recognition accuracy.

Authors: Zhang Shi , Chen Feng
Published: October 2020

Clinical hematology and hematology are one of the main courses of the Department of Medical Laboratory Science. In experimental teaching, students are required to correctly identify a variety of cells in bone marrow under a microscope, which is one of the most difficult content for students to master. The traditional experimental teaching of cell morphology has brought different degrees of influence on the teaching effect. In order to make it easier, faster and effective for teachers to teach students about cell morphology in the limited teaching time, and to allow students to more intuitively recognize various cells and increase their interest in learning, it is necessary to reform the experimental teaching methods. Computer-aided animation technology is a three-dimensional composition technology that can display things in reality in three-dimensional images. Applying computer-assisted animation technology to the teaching of hematology in medical schools can display cell morphology more vividly. This will help deepen students' understanding of classroom knowledge. Therefore, this study selected clinical undergraduates who were internships in the Department of Hematology as the research objects. 235 students in the experimental group used the 3D animation technology teaching method in computer-assisted animation technology to teach students "Morphological Changes in the Process of Cellular Immune Regulation"; 257 students in the control group used traditional clinical teaching methods. Through questionnaire surveys and personal interviews, understanding the evaluation of students and teachers on this teaching mode, and comparing the teaching effect through theoretical examination and practical skill assessment.
Conversion and Visualization of Remote Sensing Image Data in CAD
Authors: Li Hongchao , Wu Fang
Published: October 2020

In this paper, a process visualization model for remote sensing image classification algorithms is constructed to analyze the current processing characteristics of process visualization in remote sensing application systems. The usability of the model is verified in a remote sensing application system with a remote sensing image classification algorithm based on support vector machines as an example. Given the characteristics of remote sensing applications that require high visualization process and a large amount of data processing, the basic process of an image classification algorithm for remote sensing applications is summarized by analyzing the basic process of existing image classification algorithms in remote sensing applications, taking into account the characteristics of process visualization. Based on the existing process of remote sensing image classification algorithm, a process visualization model is proposed. The model takes a goal-based process acts as the basic elements of the model, provides visualization functions and interfaces for human-computer interaction through a human-computer interaction selector, and uses a template knowledge base to save processing data and realize the description of customized processes. The model has little impact on the efficiency and accuracy of the support vector machine-based remote sensing image classification algorithm during the process of process visualization and customization. Finally, the application of the model to integrate business processing of earth observation can address the problem of process customization visualization for remote sensing applications to some extent.
„W ogóle jestem niechętny dźwiękom”. Muzyka w filmie Tatarak Andrzeja Wajdy
Authors: Al-Araj Anna
Published: October 2020

The aim of this article is to interpret the musical layer of Andrzej Wajda’s 2009 movie Tatarak (Sweet Rush), based on the novel by Jarosław Iwaszkiewicz. In the first part, the author attempts to depict the complex relationship between the literary and film works of these two artists and emphasizes three main motifs used by both of them: love and death, water and women’s themes. Next, Wajda’s attitude to music is analyzed. He treats sounds as an element of everyday life and, as is typical for our times, he is aware of the “dissolution” of musical works. In the next part, the author articulates the main problems of Sweet Rush, drawing attention to both Iwaszkiewicz’s novel and Wajda’s movie. The director’s adaptation, which is full of intermedia references, revolves around the theme of death and seems to underestimate the sexual aspect of Iwaszkiewicz’s work. Finally, Pawel Mykietyn’s soundtrack to Sweet Rush is interpreted. The composer used one of his earlier Shakespeare’s Sonnets (2000), which plays the role of a leitmotif, to illustrate the most enigmatic, inexplicable scenes from Wajda’s movie. Thanks to its discrete, sparing and “austere” nature, Mykietyn’s music made the artistic composition of Sweet Rush more balanced and revealed the suggestiveness of this work.
„Pan sądzi, że koniec bliski?”. Późny modernizm, duchy kina i Wesele Andrzeja Wajdy
Authors: Stelmach Miłosz
Published: October 2020

The aim of the article is to place Andrzej Wajda’s work from the early 1970s in the late-moderist trend developing in Polish film at that time. The best example of this is The Wedding (1972), which implements modernist strategies of subjectification, self-reflection and stylisation at the artistic and narrative level. The presence of ghosts in this film especially leads to a theoretical discussion on the spectral nature of the medium of film.
Wajda autotematyczny. Wszystko na sprzedaż i Tatarak Andrzeja Wajdy
Authors: Otto Wojciech
Published: October 2020

Mise-en-abîme discourse reveals itself most clearly in 2 films by Andrzej Wajda – Everything for sale and Sweet Rush. These are connected by collective reflexive contexts, as well as by a tendency to promote formal novelty. They can be analysed from the perspective of “a film in a film”, which is a story about making a film or “a film about a film”, which is a reflection on the cinematographic means of expression.
Pisanie jako ślad i jako dar. O Próbach pisma Witolda Wirpszy
Authors: Zawadzki Andrzej
Published: October 2020

The article attempts to interpret the Attempts at writing series of poems in Witold Wirpsza’s volume of poetry entitled Superstitions. This has been read as something of a poetic and philosophical treatise dealing with nature and also the ontology of writing. Two thematic motifs, namely trace and gift, which appear in this series regularly and in numerous variants, are interpreted in the context of contemporary post-metaphysical philosophy (Derrida, Blanchot, Lévinas, Ricoeur) and presented metaphorically as writing that blurs or eradicates presence: being, subject, meaning.
Dramatografia
Authors: Krajewska Anna
Published: October 2020

The article presents the concept of dramatography as being created by “writing drama”. The author treats drama as a fluid concept, historically variable, non-binary compared to theatre, establishing performative relations interwoven with other arts. Dramatography is a response to limitations resulting from the use of the concepts of adaptation, interpretation and intersemiotic translation in the former binary system in drama and theatre. Referring to Hans Ulrich Gumbrecht’s concept of “producing presence”, the author shows the role of manifesting oneself as a counterweight to meaning in the process through which dramatography emerges.
Andrzej Wajda – reżyser przestrzeni
Authors: Purchla Jacek
Published: October 2020

At the end of the 20th century in Kraków Andrzej Wajda began to implement his architectural vision. With the Manggha Museum of Japanese Art and Technology he created a counterpoint to the Wawel hill on the opposite bank of the Vistula. Another precedent was the intimate “Wyspiański 2000 Pavilion”, finally erected between 2005–2007 at plac Wszystkich Świętych. Through his architectural vision and creations he etched himself permanently in the identity of Kraków. Wajda proved that it is possible to understand the city as a creation, as a living work of art. His imagination and determination proved that this does not only need to be through the illusion of film.
