Authors: Chua Terence Buan Kiong , Wong Johan Xin Wei , Khng Kiat Hui , Chia Michael Yong Hwa
Published: July 2023

There are limited data on how the lifestyle behaviours of school-aged children in Singapore fare against the Singapore Integrated 24-hr Activity Guidelines. One hundred and thirty-eight children ages 9 to 13 years self-reported their recreational screen time, moderate-to-vigorous physical activity (MVPA), night-time sleep duration, and health-related Quality of Life (HRQoL) in a survey package. Their lifestyle behaviours were then benchmarked against the Singapore Integrated 24-hr Activity Guidelines recommendations, specifically, (i) at least 1 hr/day of MVPA, (ii) no more than 2 hr/day of recreational screen time, and 7-9 hr/day of sleep. Association between the number of guideline recommendations met and HRQoL z-scores were explored. Of the 138 children, 6.5% met all three guideline recommendations while 29.0% did not meet any guideline recommendations. MVPA guideline recommendation was least adhered to followed by recreational screen time and sleep. The number of guideline recommendations met was significantly associated with children’s HRQoL, with an increase of 0.289 in HRQoL z-score (5.9%) for every additional guideline met. The 24-hr activity behaviours of Singapore children was sub-optimal in which the proportion of children who did not meet any guideline recommendations is higher than those who met all guideline recommendations. Nonetheless, larger cohort studies are needed to establish its prevalence. Greater dissemination of the guidelines and ameliorative programs targeted at different groups of children should be made to help support children in adopting healthy lifestyle habits.

Authors: Sarceda-Gorgoso Mª del Carmen , Penado López Rocío
Published: July 2023

En las últimas décadas, el sistema educativo español ha experimentado continuos cambios legislativos y reformas, siendo probablemente las enseñanzas de Formación Profesional las que se han visto más modificadas. Nadie duda a día de hoy de su importancia a nivel de desarrollo social y económico, pero la realidad muestra que su presencia en la investigación educativa sigue siendo escasa, especialmente si el foco de atención es su profesorado. Así las cosas, en este trabajo, bajo una metodología cualitativa concretada en una historia de vida, la voz de Jaime (profesor jubilado de FP) narra sus vivencias y experiencias durante 50 años. Sus reflexiones, contextualizadas y analizadas a la luz de la literatura especializada permiten avanzar desde el conocimiento hacia la comprensión.

Authors: Monarca Héctor , Fernández-González Noelia
Published: July 2023

O artigo apresenta uma discussão acerca das possibilidades de ressignificação do termo "qualidade" no marco das políticas educacionais que organizam a escola pública. Partindo da teoria do discurso pós-estruturalista e pós-marxista, sugere pensar a "qualidade" como termo de significado vazio e flutuante e, portanto, sujeito a disputas políticas voltadas a fixar o sentido da escola. Este trabalho foi originalmente publicado em espanhol (Fernández-González e Monarca, 2018).
Detoxification and separation of lignocellulosic biomass prior to fermentation for bioethanol production by removal of lignin and hemicelluloses
Authors: Sun Run-Cang
Published: July 2023

Lignocellulosic materials such as agricultural residues have been recognized as potential sustainable sources of mixed sugars for fermentation to bioethanol. To obtain a high overall ethanol yield and achieve an economically feasible production process, the removal of lignin and hemicelluloses improves the accessibility of cellulosic material to hydrolytic enzymes and avoids the degradation products that are inhibitory to the yeast used in the subsequent fermentation. Technological advances, e.g., environmentally friendly removal of lignin and hemicelluloses from lignocellulosic biomass prior to fermentation of the librated glucose from cellulose into bioethanol, has the potential to provide for sustainable and cost effective production of biofuel.
Swine manure solids separation and thermochemical conversion to heavy oil
Authors: Xiu Shuangning , Zhang Yuanhui , Shahbazi Abolghasem
Published: July 2023

Separation of solids from liquid swine manure and subsequent thermochemical conversion (TCC) of the solids fraction into oil is one way of reducing the waste strength and odor emission. Such processing also provides a potential means of producing renewable energy from animal wastes. Gravity settling and mechanical separation techniques, by means of a centrifuge and belt press, were used to remove the solids from liquid swine manure. The solid fractions from the above separation processes were used as the feedstock for the TCC process for oil production. Experiments were conducted in a batch reactor with a steady temperature 305 oC, and the corresponding pressure was 10.34 Mpa. Gravity settling was demonstrated to be capable of increasing the total solids content of manure from 1% to 9%. Both of the mechanical separation systems were able to produce solids with dry matter around 18% for manure, with 1% to 2% initial total solids. A significant amount of volatile solid (75.7%) was also obtained from the liquid fraction using the belt press process. The oil yields of shallow pit manure solids and deep pit manure solids with belt press separation were 28.72% and 29.8% of the total volatile solids, respectively. There was no visible oil product obtained from the deep pit manure solids with centrifuge separation. It is believed that it is the volatile solid content and the other components in the manure chemical composition which mainly determine the oil production.

Authors: Singh Gursharan , Ahuja Naveen , Sharma Prince , Capalash Neena
Published: July 2023

Gamma-proteobacterium JB, an alkali-tolerant soil isolate, produced laccase (8X103 nkat/L) in M162 medium. The optimization of process conditions (pH, incubation time, agitation, and CuSO4 concentration) for laccase production during submerged fermentation was carried out using response surface methodology (RSM) based on a central composite design (CCD). Maximum laccase production achieved was 7.4 X 104 nkat/L at pH 8.0, 210 rpm, 100 µM of CuSO4 after 60 h of incubation. This design of experiment methodology increased laccase production by 9.3 fold over the control. Experimental findings were in close agreement with the model predictions.
Detailed mass balances of the autohydrolysis of Eucalyptus globulus at 170 oC
Authors: Leschinsky Moritz , Sixta Herbert , Patt Rudolf
Published: July 2023

Autohydrolysis of Eucalyptus globulus was conducted at three different intensity levels typical for prehydrolysis kraft pulping as utilized for manufacturing dissolving pulp grades. The objective was to establish for the autohydrolysis process a detailed mass balance comprising the chemical composition of all three phases: the autohydrolysate, the released gas, and the solid residue. Carbohydrate determination involved both acid methanolysis combined with gas chromatography (GC) and sulfuric acid total hydrolysis with high performance anion exchange chromatography (HPAEC) coupled with pulsed amperometric detection (PAD); this allowed reliable quantification of neutral as well as acidic sugar units in cellulosic and non-cellulosic polysaccharides. Uronic acids present in the Eucalyptus globulus wood were progressively degraded through decarboxylation, leading to substantial carbon dioxide formation. The degree of acetylation of xylan remaining in the wood residue was clearly reduced, while the amount of bound acetyl groups in dissolved xylo-oligosaccharides (XOS) stayed relatively constant as a function of autohydrolysis intensity. The bulk of the lignin that was dissolved during autohydrolysis could be attributed to the acid-soluble lignin content of the wood. Only small amounts of Klason lignin were dissolved.
Enhancement in in vitro digestibility of wheat straw obtained from different geographical regions during solid state fermentation by white rot fungi
Authors: Arora Daljit S. , Sharma Rakesh K.
Published: July 2023

The study was carried out to find out the differences in the chemical composition of wheat straw obtained from three different regions of India, to compare their susceptibility to fungal degradation, and subsequently to evaluate the correlation between lignin loss and improvement in in vitro digestibility. Four Phlebia species were used to degrade different wheat straw samples during 30 days of incubation. In wheat straw obtained from central zone of India, most of the fungi were more selective in ligninolysis, with a moderate loss in total organic matter. The best found fungus, P. brevispora,enhanced the in vitro digestibility from 172 to 287 g/kg in north western, 165 to 275 g/kg in north eastern, and 145 to 259 g/kg in central zone with a respective loss of 163, 129, and 105 g/kg in total organic matter. Other three fungi P. fascicularia, P. floridensis, and P. radiata were also able to enhance the in vitro digestibility of all the wheat straw samples up to a significant extent. The study demonstrated that selective ligninolytic behaviour of fungi is influenced by the overall composition of wheat straw as governed by geographic location.

Authors: Bodîrlău Ruxanda , Teacă Carmen Alice , Spiridon Iuliana
Published: July 2023

Chemical modification of hardwood sawdust from ash-tree species was carried out with a solution of maleic anhydride in acetone. Wood polymers, lignin, and cellulose were isolated from the wood sawdust and modified by the same method. Samples were characterized by Fourier transform infrared spectroscopy (FTIR), providing evidence that maleic anhydride esterifies the free hydroxyl groups of the wood polymer components. Composites comprising chemically modified wood sawdust and wood polymers (cellulose, lignin)-as variable weight percentages-, and poly (vinyl chloride) were obtained and further characterized by using FTIR spectroscopy and scanning electron microscopy (SEM). The thermal behavior of composites was investigated by using the thermogravimetric analysis (TGA). In all cases, thermal properties were affected by fillers addition.

Authors: Garay Rose Marie , MacDonald Francisco , Acevedo María Luisa , Calderón Beatriz , Araya Jaime E.
Published: July 2023

The incorporation of crop residues was studied in particleboard panels (agrifibers, AG) in mixture with wood from Pinus radiata D. Don. Four crop residue stubble types were used, wheat, corn, rice plants, and rice husk. Their densities were compared. A wide array of mixtures varying from 9:1 = wood:AG to 1:9 = AG:wood were used to make the boards, from which the fundamental physical and mechanical properties were determined, to select one with the best properties and use potential. All AG were suited for board panels, although wheat and corn stubble gave better results, and their low fibre content was easily incorporated in low proportions without major modifications of processes and products.

Authors: Wu Yan , Zhou Ding-Guo , Wang Si-Qun , Zhang Yang
Published: July 2023

Rice straw (Oryza sativa L.) pulp was treated by high intensity ultrasonication to make fibrils. The rice straw fibril (RSF) material was used as reinforcement in an RSF/polypropylene (PP) composite. The influences of RSF and coupling agent (MAPP) contents on tensile properties of the composite were tested. The results showed that when RSF loading was 5%, the tensile strength rose to a maximum value of 31.7 MPa. With increasing fibril loading the tensile modulus increased first, then decreased. However, the elongation at break decreased with increasing fibril loading. There was no significant influence of MAPP content on tensile strength and elongation at break of PP and RSF/PP composite. When MAPP content was 4%, the tensile modulus of PP and RSF/PP composite all showed maximum values.

Published: July 2023

Wettability of the fire retardant treated (FRT) laminated veneer lumber (LVL) manufactured from wood veneers dried at different temperatures was investigated. Commercially manufactured veneer of beech wood (Fagus orientalis L.) was treated with borax-boric acid (BX/BA, 1:1 by weight), monoammonium phosphate (MAP), and diammonium phosphate (DAP) using a full-cell pressure process. The veneers were then dried at different temperatures (120, 140, 160, and 180°C), and experimental LVLs were made from these veneer sheets. The wettability of LVL was characterized by contact angle analysis. The lowest contact angle was obtained from LVL made from BX/BA-treated veneers, while the highest value was found for the control LVL. The CA values of these samples at each re-drying level were lower than LVLs made from untreated veneers. Re-drying of the treated veneers decreased the CA values of the LVL, while it was found higher for the LVL made from untreated veneer.
Enhancement of optical properties of bagasse pulp by in-situ filler precipitation
Authors: Kumar Pradeep , Gautam Sanjeev K. , Kumar Vivek , Singh Surendra P.
Published: July 2023

In-situ precipitation of calcium carbonate in bagasse fibers resulted in a very significant increase in specific scattering coefficient and consequently large improvements in opacity and brightness of the handsheets made from such pulp. At the same level of filler loading, the scattering coefficient of in-situ precipitated pulp was much greater than for directly loaded pulp. In-situ precipitation of calcium carbonate caused a drop in strength properties of bagasse pulp, but such loss could be recovered to a large extent by blending with other pulps. The effect of in-situ precipitation of calcium carbonate on pulp fibers was quite different for bagasse pulp from hardwood pulp. In-situ precipitation of calcium carbonate on hardwood fibers showed neither much improvement in optical properties nor much reduction in strength properties.

Authors: Kurt Şeref , Uysal Burhanettin , Özcan Cemal , Yildirim Mehmet Nuri
Published: July 2023

Composite materials and wooden dowels are being used increasingly in the construction of furniture frames and inner decoration. Yet there is little information available concerning the withdrawal strength of various fasteners, and, in particular, dowels in composite materials edged solid wood edge bandings. The aim of this study was to determine the withdrawal strengths of 6, 8, 10 mm diameter dowels produced from beech with respect to edge of a medium-density fiberboard (MDF) or particleboard (PB) edged with 5, 10 and 15 mm thickness of solid wood edge banding of uludag fir, bonded with different adhesives. According to TS 4539 standard, the effects of edge banding thickness, dimension of dowels, type of composite materials and type of adhesives used for edge banding on the withdrawal strength were determined. The highest (6.37 N/mm²) withdrawal strength was obtained in beech dowels with 8 mm diameter for MDF with 5 mm thickness of solid wood edge banding of uludag fir bonded with D-VTKA adhesive. According to results, if the hole wall and the surface of dowel are smooth then the adhesives give better mechanical adhesion with dowels and composite materials.

Published: July 2023

The intensive development of biotechnology in the last decade is largely determined by the growing requirement needs of both medicine and various industries for products of microbial synthesis, including glycosidases, in particular α-L-rhamnosidases. Their wide use to solve current biological-medical and chemical-technological problems stimulates researchers to search for compounds capable of influencing their catalytic activity. Therefore, the purpose of this work was to isolate and purify α-L-rhamnosidase from a new producer of Penicillium restrictum and to investigate multi-ligand germanium-3d-metal complexes with citric acid, phenanthroline, and bipyridine as effectors of its activity. Methods. The object of the study was α-L-rhamnosidase of P. restrictum. Its purification was carried out by gel filtration and ion exchange chromatography on TSK-gels and Sepharose 6B. The activity of α-L-rhamnosidase was determined using the Davis method with naringin as a substrate. As modifiers of enzyme activity, purposefully synthesized multiligand germanium-3d-metal complexes with citric acid, phenanthroline, and bipyridine ([Ni(bipy)3][Ge(HCit)2]·3H2O (1); [Ni(phen)3][Ge(HCit)2]·2H2O (2); [{Cu(bipy)2}2Ge(m-Cit)2]·12Н2О (3); [{Cu(phen)2}2Ge(m-Cit)2]·13H2O (4); [Zn(bipy)3][Ge(HCit)2]·2H2O (5); [Zn(phen)3][Ge(HCit)2]·3H2O (6)), were used. Results. From the supernatant of culture fluid of P. restrictum, α-L-rhamnosidase was isolated and purified 23.1 times with a yield of 0.09%. The specific activity of the enzyme was 27.8 units/mL. The enzyme was homogeneous according to gel filtration on Sepharose 6B and had a molecular mass of 50 kDa. It was established that the considered coordination compounds are able to regulate the catalytic activity of α-L-rhamnosidase of P. restrictum. All of them manifest themselves either as activators or as inert substances, no inhibition was observed. In addition, the dependence of the degree of enzyme activation by the compounds on their concentration is traced and corresponds to the following series: at a concentration of 0.01% — 1 > 6 ≈ 5 > 3 >2 ≈ 4 and at a concentration of 0.1% — 1 > 4 > 2 > 5 ≈ 6. 3. The catalytic activity is also significantly affected by the time of exposure to the compounds: at a concentration of 0.01% for 1h, the activity of the enzyme at the control level was observed for all compounds, whereas at a concentration of 0.1% for 24 h, the activity increased sharply in the presence of compounds 1 (300%), 6 (153%), and 2 (134%). The action of the others was at the control level. Conclusions. The obtained data on new complex metal compounds with an activating effect on microbial α-L-rhamnosidases. It has been established that compounds whose structural organization ensures the synergism of the action of all components are the most promising enzyme effectors in a series of coordination compounds of biologically active metals and ligands.
Professionalization, State-building and the Language Question in Forestry: The Case of the 19th Century Kingdom of Hungary
Authors: Balogh Róbert , Homor Péter
Published: July 2023

Due to its role in transforming landscapes, and because of its knowledge production that took place in a transnational space, forestry is a salient aspect of environmental history globally. Yet, the way forestry management practices evolved in the eastern part of Austria‑Hungary has a meagre presence in the literature of environmental history or in the study of empires. This paper begins with outlining routes of circulation of knowledge of forestry within the Habsburg Empire. It emphasises the role of the Academy (later College) of Forestry and Mining at Banská Štiavnica (Selmecbánya in Hungarian) but does not ignore the role of other actors outside that education institution. Then, the paper turns to how the history of professionalization of forestry and the nascent legal notions related to land contributed to the changes of the landscape in the Kingdom of Hungary in the last decades of the 19th century. The third section discusses the importance of the effort by the community of Hungarian foresters to create a Hungarian professional language.
Air Pollution in Slovenia in Socialist Yugoslavia
Authors: Sedlaček Janja , Rendla Marta
Published: July 2023

After World War II Slovenia was characterized by severe air pollution. Although it experienced rapid industrial-, and economic growth until the mid-1970s, with a focus on heavy industry especially in the first decade of the postwar era, air pollution was distributed unevenly, and pollution levels varied greatly from place to place. This paper argues that Slovenia‘s geographical characteristics and location played an important role in the large difference of air pollution levels. Other important factors that influenced air pollution were a growing societal awareness of environmental issues and government response to tackle emerging environmental problems. The main purpose of the paper is therefore to analyze influencing factors of air pollution and its harmful impact on humans and the environment in Slovenia and also within a broader Yugoslav-, and international context.
Le storie sulla morte di Ippolito Nievo: tra fatti, cospirazione e finzione
Authors: Pavlíková Alešová Táňa
Published: July 2023

The article aims to describe the stories about Ippolito Nievo’s death, as depicted in various genres of texts from the 1960s to the present. These texts exhibit a combination of essayistic and narrative elements, incorporating both factual information and the authors’ imaginative interpretations. The popularity of the topic is closely tied to the prevalence of conspiracy theories, which have gained significant traction in recent decades. Furthermore, it should probably be placed within the Risorgimento revisionism current that radicalized in the seventies of the last century and represents a broader trend of revising official historical accounts. Among the texts identified, four were selected for an in-depth analysis both from the point of view of the content and from the point of view of the authors’ approach and their formal choices. These texts do not lend themselves to a simple classification of the literary genre, falling somewhere along the continuum between a narrative essay and a novel.
Adolph Lewisohn (English edition)
Authors: Albrecht Henning
Published: July 2023

"New Yorks most valuable citizen" – this honorary title was given to Adolph Lewisohn. When he was born in Hamburg in 1849 as the son of Orthodox Jews and successful merchants, a career as a merchant was put in his cradle. In search of personal freedom he persuaded his strict father in 1867 to let him go to New York. The fact that Lewisohn, as an industrialist in the USA, will generate millions of euros in only twenty years time would have seemed like a fairy tale to the young migrant. With dedication, foresight and flexibility he builds a copper empire. For four decades he then supports countless charitable projects with millions of euros. The Hamburgische Wissenschaftliche Stiftung (Hamburg Scientific Society) also owes him one of the biggest donations it received when it was founded. This is the first biography of this exceptionally successful businessman, art collector and international philanthropist.

Introducción. La lechería especializada de trópico alto colombiano presenta elevados costos de producción, emisiones de metano y contaminación por nitrógeno en el suelo y agua; empleo de plaguicidas en las praderas, así como una producción de leche que aún no alcanza altos estándares de calidad. Lo anterior, requiere un cambio estructural en el modelo de producción con un enfoque de sustentabilidad. Además de otros aspectos, la ganadería sostenible requiere mayor complementariedad y diversidad de especies forrajeras, arbustivas y arbóreas adaptadas a las en condiciones de trópico de altura. Objetivo. Recopilar información a través de acción participativa y de innovación rural por los productores y avances de investigación de las especies Axonopus catarinensis y Smallanthus sonchifolius, forrajeras herbáceas con posible potencial productivo y ambiental (en etapa preliminar), para su integración en sistemas silvopastoriles del trópico alto colombiano. Desarrollo. A. catarinensis y S. sonchifolius son especies que podrían ser utilizadas en la alimentación básica y suplementación energética respectivamente, de vacas lecheras en el trópico alto colombiano. Aunque no existe información científica para estas condiciones, la referencia de algunos productores menciona que estas especies tal vez pueden mejorar la producción y la calidad de la leche con efectos en la economía familiar. Además, pueden contribuir a la generación de productos lácteos con atributos funcionales benéficos, que impacten en la salud humana. Conclusión. A. catarinensis y S. sonchifolius son especies que pueden tener un potencial forrajero y nutricional para incluirse en los sistemas silvopastoriles de producción lechera en el trópico alto colombiano.
Hallazgo, excursión y museo: derivas de la casa natal de William Henry Hudson en la revista El hornero
Authors: Maranguello Carolina
Published: July 2023

En el marco de la recepción argentina de la obra del escritor y naturalista William Henry Hudson, retomada desde sectores estética e ideológicamente divergentes, se indaga en el presente artículo la temprana recuperación de su figura en la revista ornitológica El hornero (1917). Como se verá, uno de los modos de su reinserción como naturalista «nacional» y escritor universal se produce a partir del descubrimiento y restauración patrimonial de su topografía afectiva, en particular de la mítica casa natal en la estancia Los veinticinco ombúes. Las tareas de gestión y difusión operadas por El hornero no se producen sobre el espacio natal como territorio cristalizado, sino sobre las derivas temporales que experimenta: la casa natal es, en primer lugar, ruina que pudo ser identificada gracias a la formidable «memoria topográfica» de Hudson y a los esfuerzos de su principal difusor, Fernando Pozzo; luego, destino de excursiones científicas y, finalmente, proyecto de casa-museo. Cada una de estas formas por las que se declina, a la vez, el hogar y la biografía de Hudson aglutina los intereses científicos, literarios y patrimoniales de la revista, y ofrece formas diversas de colaboración, intercambio y disputa entre figuras políticas y científicas nacionales y extranjeras.
Fascinación y reescritura de la Nota Roja en Temporada de Huracanes (2017) de Fernanda Melchor
Authors: Vázquez Soriano Michelle
Published: July 2023

Fernanda Melchor (México, 1982) ganó fama internacional con la publicación de su novela Temporada de huracanes (2017), relato de ficción que se inspira de la nota roja, nombre que recibe la narrativa del crimen en la prensa mexicana. Periodista de formación, Melchor ha reivindicado desde sus inicios la imposibilidad del objetivismo periodístico. Sin embargo, reconoce que el tratamiento ficcional de su novela le fue impuesto por el contexto de extrema violencia que se vive en Veracruz, su estado natal. El objetivo de este trabajo es analizar los mecanismos que la autora retoma tanto de la novela negra alternativa latinoamericana (tesis desarrollada por el escritor Diego Trelles Paz, 2017), así como del nuevo periodismo para ofrecernos un relato posible allí donde el narcotráfico y la corrupción han creado zonas inaccesibles. Por último, se reflexiona sobre la fascinación que ejerce la nota roja en su escritura: una fascinación que funciona unas veces como crítica social ante la impunidad, otras como espejo de nuestros más oscuros impulsos.

DETERMINATION AND COMPARISON METHODS OF BODY POSITIONS ON STREAM VIDEO
Authors: Bilous N. V. , Ahekian I. A. , Kaluhin V. V.
Published: July 2023

Context. One of the tasks of computer vision is the task of determining the human body in the image. There are many methods to solve this problem, some are based on specific equipment (motion capture, kinect) and provide the highest accuracy, some give less accuracy but do not require additional equipment and use less computing power. But usually, such equipment has a high cost, so to ensure the low cost of developments designed to determine the body in the image, you should develop algorithms based on computer vision technology. These algorithms can then be applied to various fields to analyze and compare body positions for a variety of purposes.

Objective. The aim of the work is to study the effectiveness of existing libraries to determine the human body position in the image, as well as methods for comparing the obtained poses in terms of speed and accuracy of determination.

Methods. A set of libraries and pose comparison algorithms were analyzed for the purpose of developing a system for determining the correctness of exercise by the user in real time. OpenPose, PoseNet and BlazePose libraries were analyzed for their suitability in recognizing and tracking body parts and movements in real-time video streams. The advantages and disadvantages of each library were evaluated based on their performance, accuracy, and computational efficiency. Additionally, different pose comparison algorithms were analyzed. The effectiveness of each algorithm was evaluated based on their ability to accurately determine and compare body positions.

As a result, the combination of BlazePose and weighted distance method can achieve the best performance in pose recognition, with high accuracy and robustness across a range of challenging scenarios. The weighted distance method can be further enhanced with techniques such as L2 normalization and pose alignment to improve its accuracy and generalization. Overall, the combination of the BlazePose library and weighted distance methods offers a powerful and effective solution for pose recognition, with high F1 index.

Results. Existing models for determining poses have shown similar results in the quality of determination with a run-up of about 2%. When developing a cross-platform software product, the BlazePose library, which has an API for working directly in the browser and on mobile platforms, has a significant advantage in speed and accuracy. Also, as the library uses extended 33 keypoint topology it becomes applicable to a wider list of tasks. In the study of comparison methods, the greatest influence on the results was exerted by the quality of pose determination.

Conclusions. Among the methods of comparison, the method of weighted distances showed the best results. The speed of position determination is inversely proportional to the quality of determination and significantly exceeds the recommended value – 40ms.
Emotional Experience and Consequences of Growing Up in a Family with Alcoholism in Adult Children of Alcoholics
Authors: Simonič Barbara , Osewska Elżbieta
Published: July 2023

Adult children of alcoholics are adults who spent a part of, or their whole childhood in a dysfunctional family, where the biggest problem was alcohol addiction in one or both parents. In families with parental alcoholism, there is usually a lot of dysfunction in interpersonal relationships and in the upbringing of the children, which does not provide a healthy and optimal developmental environment for the child. There is often physical and psychological violence, and other forms of abuse and neglect that children perceive as traumatic. All this leaves the child with severe consequences, which they also struggle with in adulthood. Unresolved and traumatic childhood content often remains repressed and unprocessed and helps shape one’s functioning in adulthood, which is frequently emotionally and socially immature. Adult children of alcoholics often have problems in experiencing and regulating their emotions, as they had to carry many emotional burdens in a dysfunctional family, while they had no real opportunity for the healthy development of emotional regulation. The article will present research on the emotional experience of children with their alcoholic parents and how they recognize related consequences in their adult lives. Using the content analysis method, we analyzed 71 anonymous forum posts on the counselling forum on the topic “Adult children of alcoholics.” The directed approach to content analysis was used to validate forum posts by people who described their childhood experiences with an alcoholic parent. We identified parts of the content that fell into two predetermined categories: emotional experience in childhood with an alcoholic parent and the experience of its consequences in adulthood. The results showed that the adult children of alcoholics mostly experienced severe feelings of fear, shame, sadness and disgust with their alcoholic parents in their childhood, and that these feelings have remained unprocessed. In adulthood, they struggle with negative consequences in the personal sphere (e.g. poor self-esteem, inferiority, anxiety, depression), in interpersonal relationships (e.g. problems in partnerships, mistrust, social phobia, parental stress, complicated relationships with parents) and in everyday functioning (e.g. coping with one’s own addiction, dysfunctional behavioural patterns), but they also recognize that because of this experience they have managed to lay the foundations of their lives differently and better. The results confirm that children are hidden victims of parental alcoholism and justify the need for psychosocial and therapeutic support even in their adulthood.

Published: July 2023

Abstract Introduction The COVID-19 pandemic led to adaptations in educational settings, such as replacing in-person with online classes. Hence, teachers increased their screen time, posing a greater risk to their mental health, quality of life, and body posture. Objective To assess and correlate the quality of life and body posture of higher education faculty during the COVID-19 pandemic. Methods This exploratory research initially contacted participants via digital invitations during the pandemic. Volunteers answered an online questionnaire with data on eligibility criteria and were later assessed regarding their quality of life (SF-36) and postural biomechanics (SAPO software). The variables in question were correlated regarding sex and age ranges with Spearman's correlation, setting the significance level at 5%. Results The sample had 21 professors of both sexes, aged 26 to 62 years (mean age of 38.47 years; SD = 8.53). The females’ mean age was 40.27 years (SD = 8.47) and that of males was 33.83 years (SD = 7.38). Males had a greater correlation between cervical spine issues and mental and physical domains, while females had body posture changes and a moderate correlation mainly with physical quality-of-life domains. Conclusion There was a correlation between body posture and quality of life in higher education faculty during the COVID-19 pandemic.

Abstract Objective: to evaluate the completeness and timeliness of notifications of cases of spotted fever (SF) held on the Notifiable Health Conditions Information System (SINAN) in São Paulo State, Brazil, from 2007 to 2017. Methods: this was a descriptive and ecological study of confirmed human cases of SF regarding completeness and timeliness of ten fields of the notification form (good if ≥ 90% for most variables); time series analysis was performed using the Prais-Winsten technique. Results: we analyzed 736 records; among essential fields, only “Discharge date” showed poor completeness (68.5%). Timeliness was good for the “Investigation” and “Closure” fields; other time lapses were not adequate. Conclusion: in São Paulo state, data completeness was good for most variables, whereas timeliness was not adequate (except for “Closure” and “Investigation”), pointing to the need for health education and communication actions about SF.
Analysis of Transgenic Cotton Plants Containing Universal Stress Protein (GaUSP-1, GaUSP-2) and Zinc Finger Transcriptional Factor (GaZnF) Genes under Drought Stress

Water is the most limiting factor for plant growth and crop productivity. Drought stress adversely affects crop yield throughout the world. Up to 50% of crop yield in Pakistan is severely affected by the shortage of water. Cotton is an important cash crop for Pakistan known as "white gold." It accounts for 8.2% of the value added in agriculture and about 3.2% of GDP. Besides, being the world's fourth-largest cotton producer, our yield per acre ranks 13th in the world. If we look at the Pakistan scenario, water deficiency is one of the major yield-limiting factors. Limitations related to conventional breeding and the advancements in plant genomics and biotechnology applications have opened new horizons to plant improvements. Therefore, in the current study, we carry out a comparative analysis to evaluate the morphological, physiological biochemical and molecular parameters in transgenic plants containing GaUSP-1, GaUSP-2 and GaZinc Finger genes under different drought stress conditions. Data showed that transgenic plants showed more tolerance as compared to non-transgenic plants. Transgenic and non-transgenic assist us in our better understanding of the drought-responsive mechanism and its effect on different plant growth traits, so, in this way, we would be able to explore drought tolerance mechanism and this will open the doors for the identification of drought-related genes.

Published: July 2023

In this research, computational fluid dynamics simulations are employed to investigate the behavior of the flow and electrochemistry of planer-type solid oxide fuel cells (SOFCs). The flow distributions in the cathode and anode of an original SOFC are simulated, and the results well agree with the experiments. To reduce non-flow areas in the cathode and anode and hence increase the operating life of the cell, a number of improved flow channel layouts are proposed and simulated. The most effective layout shows a significant reduction of non-flow areas improving flow and temperature distributions throughout the cell. However, as compared to the original SOFC, the electrical power density of the most effective channel SOFC is 12.5% lower. Further investigations are required to improve the flow and temperature distributions and increase the output power.
IMPACT OF HALL CURRENTS AND ION SLIP ON MIXED CONVECTIVE CASSON WILLIAMSON NANOFLUID FLOW WITH VISCOUS DISSIPATION THROUGH POROUS MEDIUM
Authors: Gomathi N. , De Poulomi
Published: July 2023

This article emphasizes Hall currents and ion slip impact on Casson Williamson nanofluid. Inclusion
of viscous dissipation over a mixed convective porous medium is considered. Similarity transformation
is used to convert governing equations to ordinary differential equations. Fifth order Runge-Kutta-
Fehlberg scheme via shooting technique is utilized to solve highly non-linear PDEs. Physical mechanisms
of various parameters are portrayed graphically and well explained. Major outcome reveals the
velocity profile of Casson Williamson fluid parameters. Strong effects of yield stress with viscous force
reduce the velocity flow. Consequently, the temperature and concentration profile of mixed convection,
hall, and ion slip parameters are discussed. To validate the present study, comparisons are done with
existing literature.

Estudio de reporte de casos en donde se analiza el síndrome de persistencia de los conductos de Müller en caninos machos de raza schnauzer, caracterizando la sintomatología asociada a la presencia de piometra en casos de pseudohermafroditismo. Esto hace parte de un proceso de diferenciación sexual que se inicia en el útero y continua en el desarrollo hasta alcanzar la madurez, y se divide en tres fases: sexo cromosómico, gonadal y fenotípico; una alteración en el desarrollo sexual es el síndrome de persistencia de los conductos de Müller que está presente en casos de aparente hermafroditismo masculino, el cual es hereditario, autosómico, recesivo en individuos xy, en el cual se observa la presencia de útero y otras estructuras del tracto reproductivo femenino en un animal macho, derivado de una interferencia en la respuesta a la hormona antimülleriana a nivel del receptor, que ha sido reportada en perros de la raza schnauzer miniatura. Desde esta perspectiva, en este artículo se reportan tres casos clínicos observados en una veterinaria de Bucaramanga, la sintomatología reportada indica episodios de decaimiento, fiebre, diarrea, dolor a la palpación abdominal y tenesmo, con alteraciones en la química sanguínea, en el examen clínico se observó piometra, con descarga purulenta, ginecomastía y criptorquismo, aspecto recurrente en casos de pseudohermafroditismo canino.
Contested Memories of the Past: The Politics of History Textbooks in Taiwan
Authors: Duan Lei
Published: July 2023

A Japanese colony from 1895 to 1945, and then a retreat for the defeated Nationalist government beginning in 1949, Taiwan has been struggling to find its identity. Remnants of this identity crisis can be seen in political realm, with its extreme polarization on various social, political, and historical issues. This article explores the ongoing textbook controversy in Taiwan, situating it in evolving domestic and international contexts. It suggests that Taiwan society’s representation of its colonial and Cold War past is highly contested, which was influenced by democratization. It attempts to provide an overview of the course of the textbook controversy in Taiwan from a historical perspective, and to show the reactions from educators, students, and the general public. Through an analysis of the different ways that Taiwan’s history was interpreted and represented in its history textbooks, this article shows how these factors help construct Taiwan’s contested identity.
