Renegotiating the screenplay: Drawing as a method for narrative development in a short film
Authors: Ings Welby
Published: July 2021

This article considers a non-written form of screenplay. In so doing, it illustrates a trajectory of thinking where drawing methods were employed in the development of a cinematic narrative. These visual approaches replaced creative processing normally associated with writing. In discussing the author’s short film Sparrow, the exposition examines three processes. The first method, gestational drawing, was employed as a ‘story finding’ device. The second, immersive drawing, was used to refine thematic intensity in the work. Finally, directorial drawing was employed as a catalyst for discussion when collaborating with actors and production crew. In discussing these drawing methods, the article proposes the concept of ‘screenplay’ as a verb and an active space where a developer of cinematic narratives might work beyond the parameters of writing, to ideate, refine and artistically compose image-led, cinematic narratives.

Discursos del trabajo en excombatientes de las FARC. Barreras sociolaborales en la reintegración
Authors: Hernández Zapata Edwin Alexander , Morales Herrera Milton Danilo , Vivares Porras Diana Vanessa
Published: July 2021

A partir del análisis del discurso se identifican los significados y barreras sociolaborales percibidas por excombatientes de las FARC frente al escenario de postconflicto, que deben ser comprendidas para establecer marcos de actuación en el proceso de construcción de paz. El repertorio interpretativo estar-tachado se muestra como marca ontológica en el excombatiente que le priva para acceder a distintos escenarios sociales y que entorpece la configuración identitaria, fomentando sentimientos de anulación de su utilidad civil.
La lógica internacional de la vía chilena al socialismo, cincuenta años después
Authors: Del Alcàzar Garrido Joan
Published: July 2021

La victoria electoral de la Unidad Popular (UP) chilena en 1970, en un continente hipertensionado desde 1959, propició el intento de abrir una nueva vía al socialismo sin lucha armada, pero acabó con un golpe militar en 1973. Este artículo se propone revisar las diversas lecturas de lo ocurrido bajo la presidencia de S. Allende y explicar cómo el proceso chileno revalorizó internacionalmente el concepto de democracia, dándole un contenido que llega hasta hoy.

¿Nacer en el campo – morir en la ciudad? Exclusión y expulsión de los jóvenes de áreas rurales de América Latina
Authors: Ruiz Peyré Fernando
Published: July 2021

En el presente artículo se presentan distintas fuentes de vulnerabilidad social de los jóvenes rurales en Latinoamérica. Su inserción tanto laboral como social y su paso a la “vida de adulto” se ve limitada por diferentes barreras (económicas, culturales, sociales). A su vez, las influencias de la globalización (tecnologías de la información y comunicación) llegan a todos los rincones del planeta y abre nuevas expectativas entre los jóvenes, las cuales parecen ser sólo alcanzables en las ciudades. De esta forma se pueden definir factores de "expulsión", que llevan a los jóvenes a tener que dejar su lugar de origen, y factores de "atracción", que les hacen codiciar una vida diferente – a veces sólo una ilusión – en las ciudades. Se presentan algunos aspectos de las dificultades de acceso a la tierra y de la renovación generacional en Latinoamérica. Finalmente se dan algunas recomendaciones aplicables a las políticas públicas a emprender.
Integración y reconocimiento en el contexto de sociedades heterogéneas
Authors: Riegel Christine
Published: July 2021

En la presente contribución se abordará el problemático concepto de integración – desde sus aristas políticas y empíricas- ponderando fundamentalmente las reflexiones teóricas y los resultados empíricos obtenidos en un estudio vinculado a la orientación y formas acción y comportamiento de las mujeres jóvenes inmigrantes en Alemania. Y en este sentido se intentará responder la pregunta si el concepto de integración resulta adecuado para el análisis científico y crítico de la subjetividad y la sociabilidad particularmente de la situación de los jóvenes (con y sin trasfondo cultural migratorio) en una sociedad caracterizada por la heterogeneidad. Del mismo modo se cuestiona si a través de la focalización de la integración no se reproducen las relaciones de desigualdad y las representaciones sobre la inclusión y la exclusión. Como alternativa se plantea, la autora plantea el concepto de “disposición de posibilidades y competencias de acción” (Handlungsfähigkeit) entendiéndolo como la disposición personal de posibilidades para actuar y replantear sus propias condiciones de vida.
Desafíos de la educación y respuesta formativa en los procesos de des-integración social a través del trabajo en el ámbito de la inmigración en Italia
Authors: Muriano Alessandra
Published: July 2021

El flujo migratorio registrado en Europa, en Italia posee propiedades particulares derivadas fundamentalmente por la posición geográfica de la frontera terrestre (en particular las regiones del noroeste) y su amplia frontera marítima del sur. Los extranjeros (regulares y/o clandestinos) una vez llegados a Italia intentan insertarse en el mercado laboral y normalmente consiguen un empleo en el ámbito de la agricultura, la construcción y la industria. En este artículo se analizarán los factores que favorecen y/o frenan la inclusión de los grupos extranjeros en la sociedad italiana a partir de la participación en el mercado laboral, tomando como ejemplo la situación laboral de la región Puglia -para el sector de la agricultura- y la Toscana –para el sector de la industria-. En esta reflexión se definen las particularidades de las actividades empresariales étnicas, que están caracterizadas por el aumento de la producción y los beneficios ecómicos en correspondencia con el empeoramiento de las condiciones de empleo y el nivel de vida de los grupos extranjeros trabajadores.

Modelos de elección: programas y experiencias de libertad de elección en Estados Unidos
Authors: Villamor Manero Patricia
Published: July 2021

Este artículo muestra, a través de experiencias educativas reales, la gran variedad de posibilidades que existen para llevar a la práctica un concepto tan amplio y ambiguo como la libertad de elección en educación. Otro de los intereses de estas páginas es presentar una clasificación de los modelos de programas de elección a partir de una pequeña representación de experiencias de cada tipo llevadas a cabo en Estados Unidos, el país que más ha impulsado los distintos sistemas de elección. El objetivo es ofrecer un instrumento útil para cualquiera que desee profundizar más en estos análisis, además de clarificar el campo terminológico que tanto dificulta la comprensión de esta temática. Esta sistematización puede ayudar a clarificar los heterogéneos modelos de elección y asociarlos con diferentes propósitos de los sistemas educativos.
Alterations in acid-base balance, blood gases, and hematobiochemical profiles of whole-blood and thoracic fluid in goats with contagious caprine pleuropneumonia
Authors: Tharwat Mohamed
Published: July 2021

Background and Aim: Contagious caprine pleuropneumonia (CCPP) is a highly contagious and fatal disease affecting goats and some wild ruminants. It is a cause of major economic losses in the goat industry in Africa, Asia, and the Middle East. This study aimed to investigate the acid-base balance, blood gases, and hematobiochemical profiles of whole-blood and fluid collected from the thoracic cavity in goats with CCPP. Materials and Methods: Fifty-five goats suffering from weight loss, anorexia, dyspnea, polypnea, cough, and nasal discharges due to CCPP were studied. Twenty-five healthy goats were used as controls. Diseased animals were enrolled in this study based on a positive serological latex agglutination test (LAT) that confirmed the detection of Mycoplasma capricolum subsp. capripneumoniae. The control goats were enrolled based on a negative result of the LAT. Results: Compared with a mean value of 7.38±0.04 in controls, the pH in the diseased group was 7.41±0.05. The blood pressure of carbon dioxide (PCO2), pressure of oxygen (PO2), base excess (BE), bicarbonate (HCO3), total carbon dioxide (TCO2), and saturation of oxygen (SO2) were lower in goats with CCPP than in controls. However, the anion gap (AnGap) was higher in the diseased goats than in the healthy ones. Compared with the levels in blood samples, the thoracic fluid PCO2, PO2, BE, and SO2 were higher while pH, HCO3, TCO2, and AnGap were lower. Compared with the findings in healthy goats, hematological alterations included significant increases in white blood cells and neutrophils, and a significant decrease in the red blood cell count. In the thoracic fluid, neutrophilic leukocytosis was a remarkable finding. The serum concentrations of globulin, blood urea nitrogen, and glucose, and the activities of aspartate aminotransferase (AST) and γ-glutamyl transpeptidase (GGT) increased significantly compared with those in controls. In contrast, serum concentrations of albumin, calcium, and magnesium, and the activity of alkaline phosphatase (ALP) decreased significantly compared with those of healthy animals. The activities of ALP, AST, GGT, and creatine kinase and the concentration of phosphorus were higher in thoracic fluid than the serum values in the diseased group. Conclusion: When compared with the healthy controls, goats with CCPP have metabolic acidosis. Compared with the levels in healthy goats, the blood PCO2, PO2, BE, HCO3, TCO2, and SO2 are low in goats with CCPP; however, the AnGap is higher in diseased goats.

Carmen da Silva em Claudia: um suspiro feminista na imprensa feminina do século XX
Authors: Souza Camila Pilla de Azevedo e , Casali Caroline
Published: July 2021

As revistas femininas tematizaram o cotidiano da mulher durante o século XX e conduziram suas leitoras em tendências de consumo e comportamento. Este artigo analisa as colunas publicadas pela escritora e feminista Carmen da Silva, entre 1960 e 1980, na Revista Claudia, observando especialmente a tematização da maternidade nestes textos. Para isso, optou-se pela Análise de Conteúdo de cinco colunas sobre maternidade publicadas na Revista Claudia e disponíveis na obra “O melhor de Carmen da Silva” (CIVITA, 1994). Conclui-se que os textos de Carmen da Silva, em dissonância com as matérias conservadoras da Revista Claudia, denunciavam o mito da maternidade e demais padrões de feminilidade impostos pela sociedade e, por isso, foram vanguarda do feminismo brasileiro na imprensa feminina do século XX.
Estudo do risco de contaminação de aquíferos de sub-bacias baianas
Authors: Rios Israel Henrique Ribeiro , Rabelo Jorge Luiz
Published: July 2021

As águas subterrâneas tem sua grande importância principalmente em áreas do Nordeste do Brasil, de clima semiárido. Com relação à qualidade, a contaminação de recursos hídricos subterrâneos, apesar de mais lenta, é de mais difícil remediação. Fontes de poluição como lixões, vazamentos de combustível, cemitérios, lançamentos difusos de fertilizantes e agrotóxicos, podem estar penetrando no solo e aumentando as concentrações de poluentes nos aquíferos. Dependendo das características do solo e do aquífero, como a profundidade, os eventuais contaminantes podem adentrar com maior ou menor facilidade. Esse trabalho visou medir a vulnerabilidade dos aquíferos da região de doze sub-bacias baianas, avaliar a carga contaminante pontual e difusa que pode estar sendo imposta sobre essas águas, e, com isso, observar o risco de contaminação dessas águas na área em questão. Foram coletados dados hidrogeológicos de poços ao longo da área em sistema de informação do Brasil, e informações de possíveis fontes de contaminação em diário oficial e site de órgão estadual. Foram utilizados os métodos GOD e POSH para avaliar vulnerabilidade e carga contaminante na área em questão, respectivamente. Foram observados a maior área de vulnerabilidade na área da sub-bacia do Rio Corumbataí, a predominância de postos de combustíveis no cadastro de fontes pontuais. Foram mapeadas as regiões de prioridade de proteção na área total avaliada dividindo-se em área de proteção alta, média e baixa.
Tofacitinib-Associated Cerebral Venous Sinus Thrombosis
Authors: Hakma Zakaria , Gofman Natalie , Brown Danielle , Fitzgerald Ethan
Published: July 2021

Tofacitinib is a Janus kinase inhibitor indicated to treat adult patients with moderately to severely active ulcerative colitis (UC). Although thrombosis is a known adverse event of tofacitinib, there are no reports specific to cerebral venous sinus thrombosis (CVST). We present a report of a patient presenting with a CVST several months after starting tofacitinib. Initially, this 60-year-old man with poorly controlled UC who previously had a nonthrombotic hemorrhage was found to have venous sinus thromboses of the right transverse and sigmoid sinuses. Hematological workup did not reveal any underlying hypercoagulable conditions, aside from UC. This is the first report of a patient with CVST likely resulting from the Janus kinase inhibitor tofacitinib. This case report should prompt compilation of all thrombotic events in patients receiving tofacitinib.

Приводятся результаты экспериментальных исследований высокотемпературной ползучести и длительной прочности в условиях одноосного и сложного напряженно-деформированного состояния: одноосное растяжение, кручение и их совместное действие.
Испытания проведены на лабораторных трубчатых образцах из материала ВТ6 при температуре 600 $^\circ$C в состоянии поставки и в условиях воздействия агрессивной среды путем предварительного наводораживания лабораторных образцов с различной концентрацией водорода по массе $\mathrm{C}_{m}$ равной 0.15 % и 0.3 %.
Представлена экспериментальная информация для построения материальных параметров и скалярных функций модели термоползучести с изотропно-кинематическим упрочнением, полученная из базовых экспериментов по определению: начального радиуса поверхности ползучести нулевого уровня (нулевая скорость ползучести); веера кривых ползучести при разных уровнях задаваемых напряжений с получением характеристик третьего участка на диаграмме ползучести, предшествующего разрушению образца при фиксированной температуре на заданном временном интервале; кривых ползучести при кручении до момента потери устойчивости в рабочей части образца.
По результатам испытаний на одноосное нагружение выбрано два уровня интенсивности напряжений, при различном сочетании которых проведены эксперименты в условиях сложного нагружения.
Приводятся результаты экспериментальных исследований высокотемпературной ползучести и длительной прочности при нескольких различных программах изотермического нагружения в условиях сложного напряженно-деформированного состояния для образцов из сплава ВТ6 в состоянии поставки в условиях воздействия агрессивной среды. Полученная экспериментальная информация позволяет определить необходимые материальные параметры и провести верификацию используемой математической модели термоползучести.
The use of 3D printing in centenary doors of the “Espaço Comum Luiz Estrela”: contemporary interventions in integrated goods
Authors: Martins Ribeiro Ciro Jr , Conselho Maurício Nattalia Bom , Duarte Penna Tatiana , Taveira de Souza Vanessa
Published: July 2021

This paper presents forms of contemporary interventions in integrated goods based on 3D printing pieces to replace missing parts. In this specific case, they were used on wooden doors, belonging to the “Espaço Comum Luiz Estrela”, an eclectic building from the beginning of the 20th century in Belo Horizonte, Minas Gerais, Brazil. Abandoned by the State, the building has been occupied by a collective of artists who propose the creation of a self-managed cultural space. The original front facade doors, which were quite damaged were chosen to start the restoration, because they represent the resignification of this space: a common space, open to all. Through the doors’ interventions, new technologies were used to supply the lack of specialized wood labor. Consequently, a contemporary aesthetic has been generated in a century-old element, in addition to saving materials and time during its restoration process.
A survey of acrylic sheet in Portuguese art collections
Authors: Babo Sara , Lia Ferreira Joana
Published: July 2021

Acrylic sheet, also known by the commercial names Plexiglas or Perspex, consists of poly(methyl methacrylate) (PMMA). Attractive to artists since its development in the 1930s, it became especially popular during the 1960s. In Portugal, knowledge about its use by artists and its condition is scarce. In this work, the main Portuguese art collections were surveyed with the goal of gaining an overview of the use of acrylic sheet in the Portuguese art context and its current condition. The paper describes the methodology used and the results obtained regarding 137 artworks by 69 different artists registered as containing acrylic. Results show that this material is being used by Portuguese artists at least since the 1960s. It has been used in several artistic forms, from painting and sculpture to photography, installation, objects/reliefs, and artist books. Most of the artworks were in good or fair condition. The main problems observed were dust and dirt deposits, abrasion, and scratches.
Research Study in Two Unpublished Artworks of the Important Greek Artist, Theofilos Hadjimichael (1870-1934)
Authors: Mouzakiotou Stella , Laskaris Nikolaos , Ganetsos Theodore
Published: July 2021

The purpose of this research is to highlight, study and publish two very important signed works of the Greek folk painter - hagiographer of modern Greek art, Theofilos Hatzimichael (1870-1934), which belong to a private collection. These are the works: 1. "New type of rural Mytilene with its coexistence that weaves in rocket", wood painting, time: 1931. 2. "The young Hercules Panais Koutalianos in England", wood painting, time: 1932. The dominant element in Theofilos' work is Greekness and the illustration of the Greek folk tradition and history. He spent most of his life in Pelion, while in 1927 he returned to Mytilene. In Mytilene, despite the mockery and teasing of the people, he continues to paint, making several murals in villages, for a fee, usually for a plate of food and a little wine. Many of the works of this period have been lost, either due to physical damage or destruction by their owners. In Mytilene, he was met by the renowned art critic and publisher Stratis Eleftheriadis (Tériade), who lived in Paris. Eleftheriadis owes much to the recognition of the value of Theophilos' work and its international promotion, which, however, took place after his death. Through the present study of the aforementioned works, we will highlight unknown aspects of the last phase of Theophilos' artistic creation, a period particularly important for the thorough and kaleidoscopic knowledge of his work, since it is the period that is visible through his color palette and His stylistic choices are the optimism and security conveyed to him by the acquaintance and support he receives from Eleftheriadis. Finally, the present work for the study of Theophilos' two unpublished works will be scientifically strengthened by utilizing the achievements of technology. Specifically, in the context of current study, the portable non-destructive techniques of the Non-Destructive Techniques Laboratory of the University of West Attica will be used. In particular, the techniques will be used: 1) portable Raman spectroscopy, for the authenticity test of the paintings 2) portable XRF spectroscopy, for the qualitative analysis of the data concerning the colour palette of the creator, compared to other identified paintings by NTUA.

Published: July 2021

Human societies have always a golden sign to show the noticeable spectacles of coexistence with their environments, precisely the impact of plants in every phases of their life. Several qualitative as well as quantitative approaches are taken into account to emphasize the effective integration of plants into a medical system. Therefore this experiment was designed to standardize and evaluate the health of active plant-extract and their dynamic use in healthcare system to open a new era in drug designing. In order to maintain this knowledge, plant extract of ginger and garlic from native and hybrid source were chosen (July 2018 to July 2019 from different zone of Bangladesh) in this experiment and sensitivity pattern of these extracts against two enteric disease causing organisms Bacillus cereus and Vibrio cholerae were conducted to investigate the role of these natural sources as medicinal plants. To compare the authenticity and efficacy of the plant extracts, selected strains were also challenged with conventional antibiotics. Finally, the results portrayed that the ethanoic and methanoic extract of both native garlic and ginger extracts showed more prominent sensitivity towards the gram negative organisms as compared to the foreign plants of same genera.
Quarantine, Contact Tracing, and Testing: Implications of an Augmented SEIR Model
Authors: Hornstein Andreas
Published: July 2021

I incorporate quarantine, contact tracing, and random testing in the basic SEIR model of infectious disease diffusion. A version of the model that is calibrated to known characteristics of the spread of COVID-19 is used to estimate the transmission rate of COVID-19 in the United States in 2020. The transmission rate is then decomposed into a part that reflects observable changes in employment and social contacts, and a residual component that reflects disease properties and all other factors that affect the spread of the disease. I then construct counterfactuals for an alternative employment path that avoids the sharp employment decline in the second quarter of 2020, but also results in higher cumulative deaths due to a higher contact rate. For the simulations a modest permanent increase of quarantine effectiveness counteracts the increase in deaths, and the introduction of contact tracing and random testing further reduces deaths, although at a diminishing rate. Using a conservative assumption on the statistical value of life, the value of improved health outcomes from the alternative policies far outweighs the economic gains in terms of increased output and the potential fiscal costs of these policies.

Published: July 2021

Remote sensing (RS) water depth inversion is an important technology and the method of water depth measurement. Taking the waters around the islands outside the Pearl River Estuary as an example, five optical RS depth inversion algorithms were introduced. Then, five water depth inversion models were trained through the HJ-1B satellite RS image and the measured water depth data. The results show that the mean absolute error (MAE) of the deep learning model was the smallest (2.350 m), and that the distribution of predicted water depth points was closest to the actual value. Deep learning has been widely used in RS image classification and recognition and shows its advantages. Therefore, the deep learning model was applied to extract the depth of the shallow water. Meanwhile, the obtained inversion effect map is closest to the actual contour map. The water depth inversion performance of back propagation neural network model is better than that of the radial basis function (RBF) neural network model. Besides, the inversion accuracy of the RBF neural network may be affected due to the small amount of data and the improper number of hidden neurons. The results show broad application prospects of machine learning algorithms in RS water depth inversion. Also, this study provided data support for model optimization, training, and parameter setting.
Can pulse wave velocity (PWV) alone express arterial stiffness? A neglected tool for vascular function assessment
Authors: De Luca Mariarosaria , Iacono Olimpia , Valente Valeria , Giardino Federica , Crisci Giulia , Lettieri Maddalena , Marra Alberto , Giallauria Francesco , Oliviero Ugo
Published: July 2021

Arterial stiffness, defined as the rigidity of the arterial wall, is the consequence of vascular aging and is associated with the full spectrum of cardiovascular diseases. Carotid-femoral pulse wave velocity (cf-PWV) is the gold standard method for arterial stiffness evaluation: it measures the velocity of the arterial pulse along the thoracic and abdominal aorta alongside arterial distensibility. Its value rises as stiffness progresses. Cf-PWV is helpful to assess residual cardiovascular risk (CVR) in hypertension (HT). In fact, an increase in pulsatility and arterial stiffness predicts CVR in patients affected by arterial HT, independently of other risk factors. Arterial stiffness can predict cardiovascular events in several other clinical conditions such as heart failure, diabetes, and pulmonary HT. However, cf-PWV has not been yet included in routine clinical practice so far. A possible reason might be its methodological and theoretical limitations (inaccuracy in the traveled distance, intra and interindividual variability, lack of well-defined references values, and age- and blood pressure-independent cutoff). To exceed these limits a strict adherence to guidelines, use of analytical approaches, and possibility of integrating the results with other stiffness examinations are essential approaches.
The Role of Internal Irreversibilities in the Performance and Stability of Power Plant Models Working at Maximum ϵ-Ecological Function
Authors: Valencia-Ortega Gabriel , Levario-Medina Sergio , Barranco-Jiménez Marco Antonio
Published: July 2021

The proposal of models that account for the irreversibilities within the core engine has been the topic of interest to quantify the useful energy available during its conversion. In this work, we analyze the energetic optimization and stability (local and global) of three power plants, nuclear, combined-cycle, and simple-cycle ones, by means of the Curzon–Ahlborn heat engine model which considers a linear heat transfer law. The internal irreversibilities of the working fluid measured through the r-parameter are associated with the so-called “uncompensated Clausius heat.” In addition, the generalization of the ecological function is used to find operating conditions in three different zones, which allows to carry out a numerical analysis focused on the stability of power plants in each operation zone. We noted that not all power plants reveal stability in all the operation zones when irreversibilities are considered through the r-parameter on real-world power plants. However, an improved stability is shown in the zone limited by the maximum power output and maximum efficiency regimes.
Reflecting on the quantitative turn in linguistics
Authors: Kortmann Bernd
Published: July 2021

Linguistics, English linguistics in particular, has witnessed a remarkable quantitative turn since the 1990s and the early 2000s. It was a turn both in scale and in quality, a turn concerning the degree (including the degree of sophistication) to which quantitative empirical studies, statistical techniques, and statistical modelling have come to be used and determine linguistic research. Which role have corpus linguistics and probabilistic linguistics, including usage-based approaches, played in this development? Has this turn been to the detriment of qualitative methods, or even of linguistic theorizing in general? Has linguistics reached the point of a “quantitative crisis”, or is it still a discipline characterized by a healthy equilibrium, if not mutual reinforcement, of quantitative and qualitative approaches? What are, or should be, major repercussions of the strong quantitative turn for the publication system of (English) linguistics? These are the major overarching questions underlying the reflections offered in this opinion paper.

Hyperbolic materials offer much wider freedom in designing optical properties of nanostructures than ones with isotropic and elliptical dispersion, both metallic or dielectric. Here, we present a detailed theoretical and numerical study on the unique optical properties of spherical nanoantennas composed of such materials. Hyperbolic nanospheres exhibit a rich modal structure that, depending on the polarization and direction of incident light, can exhibit either a full plasmonic-like response with multiple electric resonances, a single, dominant electric dipole or one with mixed magnetic and electric modes with an atypical reversed modal order. We derive conditions for observing these resonances in the dipolar approximation and offer insight into how the modal response evolves with the size, material composition, and illumination. Specifically, the origin of the magnetic dipole mode lies in the hyperbolic dispersion and its existence is determined by two diagonal permittivity components of different sign. Our analysis shows that the origin of this unusual behavior stems from complex coupling between electric and magnetic multipoles, which leads to very strong scattering or absorbing modes. These observations assert that hyperbolic nanoantennas offer a promising route towards novel light–matter interaction regimes.

Leucaena leucocephala (Lam) de Wit is a fast-growing tree species often used as lead (shade) tree that can be cultivated in Malaysia. This species has potential as an alternative resource for the Malaysian furniture and panel board industries in the coming years because of a shortage of the current frequently used raw material (rubberwood). A study on growth performance and potential as particleboard resource material was done. In terms of growth performance, the preliminary study indicated that Leucaena trees grew at a rate of 44% from the first month to the forth month and 43% from 6 to 12 months. As for particleboard manufacturing, Leucaena: Rubberwood admixture bound with urea formaldehyde (8%, 10%, and 12% resin content) to a density of 700 kg/m3, showed promise of usability when all boards pass the Type P2 board requirement of EN312:2010. In general, L. leucocephala wood is a potential raw material for the manufacture of wood composites.

Several physical and mechanical properties can characterize tissue papers. In particular, low grammage but high values of bulk, flexibility, liquid absorption capacity, and softness are common properties for tissue papers. These properties must be adapted to meet the requirements of the final consumer, which can vary greatly in different countries. This work resulted from a study regarding the impact of two different stacking sequences of 5-ply toilet paper with configurations 1 and 2 (deco:micro embossing of 3:2 and 2:3 plies, respectively), which had the same base tissue papers in each mother reel, on their mechanical behavior and absorption capacity. The stacking sequence of the plies influenced the properties of the finished toilet paper. For configurations 1 and 2, after the embossing process, bulk increases of 46% and 40%, respectively, and water absorption capacity increases of 2% and 17%, respectively, were registered. In this case, the bulk increase was not the key property that influenced the water absorption capacity. Regarding mechanical properties, both configurations showed a higher negative impact caused by the deco embossing. For commercial purposes and to adhere to the final consumers’ preferences for toilet paper, configuration 1 was more suitable for mechanical strength, and configuration 2 was more suitable for absorption capacity.
Application of enzymes for the reduction of PFI revolutions in the secondary pulping process and characteristics of thermomechanical pulp

Published: July 2021

Three enzymes, mannanase, xylanase, and cellulase, were applied for hydrolysis of thermomechanical pulp (TMP) primary discharge prior to PFI refining, aiming to study the effect of enzymatic hydrolysis on the required number of PFI revolutions. The quantity of reducing sugar was used as an indicator for enzyme hydrolysis efficiency. Then, under the optimized enzyme loading, treated and un-treated pulp were refined with different PFI revolutions. Subsequent fiber characteristics, such as fiber length and fines content were examined. Under the optimized enzyme loadings and a given 20000 PFI revolutions, in comparison with the control pulp, mannanase and xylanase pre-treatment could save PFI refining revolutions by 20% and 25%, respectively. There was no significant energy savings for the cellulase-treated pulp. During the hydrolysis, the enzyme broke down TMP fibers into shorter pieces and yielded more fines than the control pulp. Among the three enzymes, cellulase showed the highest efficiency in fiber breakdown, mannanase in the middle, xylanase the lowest. Longer hydrolysis time (more than one hour) had no evident effect on the pulp freeness reduction and reducing sugar production. Among the three enzymes, under the optimized enzyme loading, cellulase was the most efficient for enhancing production of reducing sugars.
Unidentified Names in the “First” Notebook of F. M. Dostoevsky (1864–1865)
Authors: Zavarkina Marina
Published: July 2021

The notebooks of F. M. Dostoevsky contain personal names and titles of works, many of which were left without comment or were reproduced incorrectly from the manuscript. The article examines the names of real persons from the “first” notebook of Dostoevsky in 1864–1865 (presently at The Russian State Archive of Literature and Arts. F. 212.1.3), the attribution of which was problematic for preceding researchers. In addition to academic publications, such as the Complete Works in 30 volumes or the series of Literary Heritage (vol. 83), the same issues arise in some modern electronic publications. Sometimes there is a confusion of names in the comments, for example, Panteleev / Panteleeva / the Panteleev brothers; similar confusion is observed with the Filippov brothers. Some names suggest a different reading: Blagosvetlov instead of Blagoeva, Voronov instead of Voronin. Dostoevsky often indicated the names of works instead of the names and surnames of the authors. This applies primarily to the entries in the Epoch magazine. Many of these works have never been published anywhere, thus, establishing the identity of the authors is difficult for the researcher. Within the framework of this study, individual entries from the “first” notebook of Dostoevsky were read with regard to the typical features of the writer's handwriting, and new explicatory comments to them were proposed, the failed authors of the Epoch magazine were identified (B. A. Pavlovich, V. A. Sleptsov, V. M. Sikevich, N. A. Neklyudov). The interpretation and attribution of personal names from Dostoevsky's notebook of 1864–1865 presented in the article are of a debatable nature and require further elaboration.

Romani catching up in East-Central Europe: Alternative strategies
Authors: Katalin Forray R.
Published: July 2021

According to our initial assumption, there would be two characteristic strategies for Romani catching up. One strategy is to lift the Romanies out of poverty and bring their living conditions closer to the average living conditions of the majority society. According to the other strategy, Romanies create a national minority in the majority society. It should be supported so that the members of the community could preserve their national characteristics and exercise their minority rights. By reviewing the literature (e.g., Armillei 2014; Boscoboinik & Giordano 2008; Ladányi & Szelényi 2016) we searched in which country which strategies are being followed by current governments. The result is that these strategies coexist within a country and are increasingly intermingled according to existing governments. The reason for this phenomenon is the recent changes in Romani societies and the emergence of new middle classes. There are both economic and cultural conditions for emerging these middle classes. A successful Romani strategy has to contain therefore, both economic and cultural actions. The governments of the region must contribute not only to the catching-up of the Romanies but also to the formation of their Romani middle classes.
