Luffa reinforced polylactic acid (PLA) bio-composites were prepared and examined. The luffa surface was treated using three chemicals, i.e., sodium hydroxide, 3-aminopropyltriethoxysilane, and acetic anhydride, which enhanced luffa compatibility with PLA. Mechanical testing was done on the chemically modified luffa reinforced PLA bio-composites, i.e., tensile, flexural, hardness, and thermal. Infrared spectral functional group and morphological analyses were performed on each sample. The results showed increases in tensile and flexural strength of 7.1% and 6.9% for sodium hydroxide, 5.7% and 1.4% for silane, and 4.3% and 0.4% for acetylation, respectively, especially to the surface-treated samples at 15 wt.% fiber volume, and a decrease in water uptake (%). Fourier transform infrared spectroscopy confirmed that the chemical surface treatments were successful with the removal of lignin and hemicellulose structures, which cause the surface structure of the modified fiber to be rough. Smooth surfaces were observed through SEM images. Thermal stability was enhanced due to improved interfacial bonding between luffa and PLA, eliminating other constituents and impurities. Moreover, the morphological analysis showed improved bonding compatibility between the luffa and PLA matrix.
Making ultra-thin high density fiberboard using old corrugated container with kraft lignin
Authors: Luo Peng , Yang Chuanmin , Wang Tao
Published: May 2022

Ultra-thin high-density fiberboards (HDFs), a newly developed variety of fiberboards, broaden and extend the applications of medium thick medium- and high-density fiberboards and are capable of replacing cardboards for most applications. Old corrugated container (OCC) is an important packaging solid waste. The mechanical strength of OCC deteriorates after repeated recycling processes. Application of OCC fibers for value-added ultra-thin HDFs can be of much interest. Because the OCC fibers have more surface area than the wood particles, the resin coverage per surface area of the OCC is much lower than wood particles during panel board formation. Therefore, the performance of the OCC fiber-based board is poor and the resin adhesive consumption is high. To overcome these problems, a novel method of using OCC to make ultra-thin HDFs was developed and investigated. In this work, the OCC was shredded and pulped before making the ultra-thin HDFs. To protect consumers from exposure to harmful formaldehyde, kraft lignin was used as a binder. The target density and thickness of the ultra-thin HDFs were 1.0 kg/m3 and 2 mm respectively. The resulting ultra-thin HDFs were evaluated for their physical and mechanical properties. Comparisons with the Chinese Standards

Se investigó la variabilidad interanual de la temperatura del agua superficial del lago (LSWT, por sus siglas en inglés) usando imágenes MODIS para el invierno del 2001-2014 en el lago Titicaca 15°45'00''S - 69°25'00''O. Utilizamos el producto MOD11A2 de temperatura de la superficie terrestre (LST), que renombraremos como LSWT. Los datos LST de detección remota se obtuvieron del sensor MODIS a bordo del satélite Terra como un compuesto de 8 días, con una resolución espacial de 1 km. Durante el invierno austral (junio, julio, y agosto), el producto MOD06L2 cloud fraction mostró el cielo despejado sobre el lago Titicaca en invierno. Se analizó la distribución de LSWT por medio de imágenes, series de tiempo y el coeficiente de variación (Cv). Se consideraron dos regiones del Titicaca, Lago Mayor (LM) y Lago Menor (Lm). Se descubrió que el coeficiente de variación de LSWT para la cuenca principal (LM) durante el periodo de estudio no mostró cambios significativos (Cv < 9%). El valor promedio de la temperatura superficial de la cuenca principal (LM) encontrado en esta investigación es aproximadamente 13.224 °C y del lago menor (Lm) es igual a 12.695 °C. Finalmente usando el análisis de componentes principales se observa una tendencia positiva desde el 2004 hasta el 2010, año del máximo del PC1 para el Lago Mayor y Lago Menor.
Hamiltonian formalism of the Bianchi's models
Authors: Valenzuela Mississippi
Published: May 2022

Lately the Cosmic Background Radiation (CMB) data have resulted in anomalies or deviations with respect to the standard model of cosmology, which has led several cosmologists to consider alternative models to the standard model (homogeneous and isotropic), such as the Bianchi models, which are homogeneous but anisotropic. Based on these motivations to consider alternative models, we propose to study, in the present work, the algebraic classification of the Bianchi models and each of the Bianchi space-times, applying the ADM formalism of general relativity in its Hamiltonian version and the groups G3 . The dynamic equations are shown with the help of the Hamiltonian density H and the Poisson parentheses, in other words, the equations of motion are presented for each of the Bianchi space-times. Some theoretical consequences of these equations are discussed when we take the limit Ω → -∞ and the fixed parameters β + and β - , consequently, we find that the dependent part of the gravitational potential from the Hamiltonian Density tends to zero and from the equations of motion we find the constant of motion, pΩ = pβ+ = pβ- = constant .

Structure formation at high rates of heating during welding of steels
Authors:   Ukrenergymachines JSC, Kharkiv, Ukraine, Artyomova S. V.
Published: May 2022

This paper deals with structure formation in weld joints of quenching steels 15Cr5Мo and 12Cr1МoV as made by “short cycle” argon-shielded welding as well as with the possibility of control of transformation and quality for weld joints by the thermodynamic cycle of welding. It is demonstrated that where the developed technology is applied, the weld metal is sound, defect-free, of martensitic-ferritic structure. In the weld-affected zone of steels at high heating rates and with short time of metal exposure to temperatures exceeding critical transformation temperatures in heating, non-uniform austenite of low homogeneity is formed, in which the carbide phase containing alloy elements undergoes partial dissolution. As a result, the austenite breakdown in cooling (in spite of high rates) takes place in the bainitic range as well as in the martensitic range. In the weld-affected zone of steel 12Cr1МoV, the bainitic structure predominates while the weld-affected zone of steel 15Cr5Мo shows the bainitic-martensitic structure mainly. During weld joint inspection by shock loading testing, the metal having the above structure experiences bending or ductile fracture. The process parameters were determined, with which structures of high brittle fracture resistance are formed. The technology developed was implemented in tube studding for manufacture and repairs of cooling panels; it is recommended for common use in industrial applications. Keywords: welding, quenching, thermodynamic cycle, argon, bainite, quality, application.

Published: May 2022

Varicella-zoster virus is an exclusively human pathogen of an acute exanthematous illness usually linked with childhood. Although the disease is commonly considered benign, varicella-zoster virus bears the potential of causing a wide range of different complications, including central nervous system manifestations. In this paper, an assessment of long-term sequelae and the quality of life in a cohort of patients with neurological complications who survived an acute episode is discussed. We enrolled a total of 71 patients aged two months to 16 years with the diagnosis of varicella complicated by central nervous system disease into the study. Data were collected after their discharge from the hospital by mail and by telephone call interviews using standardised questionnaires. The time from the discharge to the filling of the survey varied between the patients, with a median time of 5.4 years. The collected data were analysed, and the results were compared with the literature. The diagnosis of ischaemic stroke and encephalitis was linked to the most unfavourable outcome, as opposed to acute cerebellar ataxia associated with the most favourable prognosis. Neuropsychological performance should be further monitored to prevent a decrease of independence in everyday performance.

Uterine tumors are a challenge encountered by every gynecologist in clinical
practice. In the era of increasing incidence of endometrial cancer in the general
population of women at reproductive age, compared to other genital malignancies, we
should not forget about other tumors originating from the mucous and muscular layer of
the uterus. Clear ultrasonographic differentiation of uterine tumors into benign
(myomas) and malignant (sarcomas) lesions may sometimes prove impossible. Myomas, the
most common uterine tumors, are characterized by discrete vascularization on color
Doppler and high blood flow velocity as well as the lack of early diastolic notch on
Doppler ultrasound. Sarcomas, on the other hand, show characteristic rich
vascularization. Rapid tumor growth should also be noted when making the diagnosis.
There are multiple known causes of uterine tumors. So far, no clear Doppler flow markers
have been identified to characterize benign and malignant lesions.

The aim of this article is to provide a short review of the literature concerning
the basic principles, usefulness and limitations of ultrasound-guided biopsy of
musculoskeletal soft tissue tumors, with particular focus on core needle biopsies.
Musculoskeletal soft-tissue tumors represent a rare and complex group of heterogeneous
lesions. Prompt diagnosis of these uncommon lesions can improve the outcome and increase
the patient survival rate. A biopsy examination of soft-tissue tumors with imaging
modalities is necessary in all cases of aggressive or undetermined lesions. Although
fine needle aspiration can be helpful for the biopsy of certain tumor types, core needle
biopsy is a standard procedure in most tertiary sarcoma centers. It has a high
diagnostic accuracy, low complication rate and lower price in comparison to open biopsy,
and can replace it in the majority of cases of soft-tissue tumor assessment. However,
the examining physician has to be familiar with the technique, and the strengths and
potential difficulties in performing ultrasound-guided biopsy, as well as possible
solutions to obstacles. Several recently developed ultrasound techniques can be helpful
and improve the outcome of imaging-guided biopsies of musculoskeletal lesions.
Quality and functional features of gelatine extracted from chicken skin in comparison with commercial gelatines from porcine, bovine and piscine
Authors: Karim B.F. , Cansu Ü. , Boran G.
Published: May 2022

Poultry processing industry produces large quantities of by products (skin, bone, and feather) that contain significant amounts of protein. The source of gelatine is of great concern for some societies including Muslims, Hindus, and Jews as gelatine is mostly obtained from porcine sources. In the present study, gelatine was obtained from chicken skin and some quality and functional features were evaluated in comparison with commercial gelatines from porcine, bovine, and piscine sources. Chicken skin gelatine formed stable foams by a foaming stability of 83.3% as well as high emulsion activity of 72.8 m2 g−1 compared to commercial gelatines. On the other hand, gel strength and viscosity of chicken skin gelatine were 307 g and 2.5 cP, respectively, and significantly lower than that of commercial gelatines due to high content of impurities. The results concluded that chicken skin may be used in gelatine manufacturing upon efficient removal of fat, which was the most abundant component in the dry matter of chicken skin.
CONQUISTANDO CORAÇÕES E MENTES: AS COMPETÊNCIAS SOCIOEMOCIONAIS COMO REFLEXO DA RACIONALIDADE NEOLIBERAL EM COLEÇÕES DIDÁTICAS DE PROJETO DE VIDA
Authors: Silva Francisco Vieira da
Published: May 2022

O objetivo deste texto consiste em analisar coleções didáticas de Projeto de Vida, com vistas a estudar como as competências socioemocionais são abordadas em tais materiais didáticos e de que forma refletem os anseios da racionalidade neoliberal. Para ancorar teoricamente o estudo, busca-se respaldo, sobretudo em Foucault (2008), em Dardot e Laval (2016), em Lemos e Macedo (2019), em Ciervo (2019), em Smolka et al (2015), dentre outros. Acerca da metodologia, convém frisar que se trata de um estudo descritivo-interpretativo de cunho documental, seguindo uma abordagem eminentemente qualitativa. O corpus é formado por fragmentos extraídos de três coleções didáticas de Projeto de Vida, aprovadas pelo Programa Nacional do Livro e do Material Didático (PNLD), edição de 2021. Por meio da análise, pode-se ponderar que há uma relação direta entre as competências socioemocionais e a racionalidade neoliberal, porque os jovens são orientados a regular suas emoções, com vistas a aperfeiçoar o capital humano e, como corolário, construir o projeto de vida com base naquilo que é desejável no cerne de uma racionalidade matizada pela concorrência, individualidade, resiliência e autonomia.
Comprehensive Study of Lung Cancer Proton Therapy with Injection of GNPs
Authors: R Khoramdel , SN Hsseinimotlagh , Z Parang
Published: May 2022

The use of Radiation Therapy (RT) in lung cancer has shown some exciting and sometimes disappointing advances in recent years. Protons compared with photons interact differently with human tissues, and can be used to improve patient care suffering lung cancer. A new strategy is the simultaneous injection of Nanoparticles (NPs) with proton radiation to the tumor which has been given over a decade to improve conventional RT. In this work, Proton Beam Therapy (PBT) with Gold Nanoparticles (GNPs) is used as part of a combination program for the treatment of advanced localized lung cancers. The purpose of this paper is developing the complex GEANT4 (G4) model on the human lung and predict the distribution of absorbed dose in lung tumors during proton therapy without and with high-Z injection of GNPs. Thus, the distribution of the absorbed dose in lung tumor for four modes of Bethe-Bloch’s relativistic quantum theory, G4 simulation model, hartree-fock-roothaan wave functions and the bortfeld theoretical model without and with the injection of GNPs in predicted phantom of the lung are compared.

The sum of lognormal variables has been a topic of interest in several fields of research such as engineering, biology and finance, among others. For example, in the field of telecommunications, the aggregate interference of radio frequency signals is modeled as a sum of lognormal variables. To date, there is no closed expression for the probability distribution function (PDF) of this sum. Several authors have proposed approximations for this PDF, with which they calculate the mean and variance. However, each method has limitations in its range of parameters for mean, variance and number of random variables to be added. In other cases, long approximations as power series are used, which makes the analytical treatment impractical and reduces the computational performance of numerical operations.  This paper shows an alternative method for calculating the mean and variance of the sum of lognormal random variables from a computational performance approach. Our method has been evaluated extensively by Monte Carlo simulations. As a result, this method is computationally efficient and yields a low approximation error computation for a wide range of mean values, variances and number of random variables.

Background. Oncoplastic breast resections with perforator flaps are relatively common now; however, many studies demonstrate contradictory results, especially in terms of long-term outcomes.

Objective: to assess short-term and long-term outcomes of oncoplastic breast resection with defect repair using perforator flaps.

Materials and methods. This study included 62 breast cancer patients who underwent oncoplastic breast resection with defect repair using local perforator flaps, including lateral intercostal artery perforator (LICAP) flaps (40.3 %), lateral thoracic artery perforator (LTAP) (19.4 %), anterior intercostal artery perforator (AICAP) (27.4 %), and medial intercostal artery perforator (MICAP) (12.9 %) flaps. The assessment of oncological, functional, and aesthetic outcomes was performed in patients who were followed-up for at least a year (n = 57). Mean follow-up time was 26.5 months (range: 14–38 months).

Results. The following complications were registered among the patients studied: seroma in the area of excised primary tumor (8.1 %), insufficient blood supply of the flap that caused focal lipofibrosis/liponecrosis (3.2 %), positive resection margin (3.2 %), low position of the submammary fold (11.3 %), locoregional recurrence (0 %), generalized process (3.5 %). All women evaluated their functional and aesthetic result as good or excellent. According to BCCT.core 3.0, 91.3 % of patients achieved good and excellent results.

The aim of this study is to reveal the attitude levels of prospective teachers, who are the teachers of the future, about sustainable environmental education. This study is a quantitative research based on survey design. 471 prospective teachers studying in different departments of the Education Faculty of a university in Black Sea region participated in the study. The data were collected from prospective teachers studying at the departments of Science Teaching, Mathematics Teaching, Preschool Teaching, Primary School Teaching and Social Sciences Teaching. All of the prospective teachers were reached through an online form and 471 participants were reached as a result of the participation of volunteering students. “Sustainable Environmental Education Attitude Scale” was used in the study. SPSS 22.0 package program was used in the analysis of data. As a result of data analysis, it was found that prospective teachers who were studying at the department of Science Teaching, those who were members of non-governmental organizations related with the environment, and those who followed printed or online publications and female prospective teachers had higher attitudes towards environmental education. According to the results obtained, it may be an effective solution to provide education to prospective teachers about sustainable environment and to add more courses in the curriculum on these topics.

Araştırma, büyükannelerin çocuk-torun büyütme deneyimlerinin ve büyükanneler ile anne-babaların çocuk büyütme yaklaşımlarının karşılaştırıldığı fenomenolojik desenli nitel bir çalışmadır. Araştırmaya yaşları 50 ila 60 arasında değişen 14 büyükanne katılmıştır. Çocuğunu kendi büyütmüş olma, her iki ebeveyni çalıştığı için torununu büyütüyor olma araştırmaya katılım için belirlenmiş kriterlerdir. Katılımcıların büyüttükleri torunların yaşları bir ile altı arasında değişmektedir. Veriler, yarı yapılandırılmış görüşme formu aracılığıyla toplanmıştır. Araştırmanın verileri içerik analizi yöntemi ile incelenmiştir. Araştırmanın bulgularına göre büyükannelerin torun büyütme ve çocuk büyütme deneyimleri kıyaslandığında; ilgi/özen gösterme, sevgi gösterme, zaman ayırma, öncelik verme, ceza verme, sabırlı/hoşgörülü olma, sorumluluk, araştırma yapma, değer öğretimi ve özür dileme açısından farklılaştığı görülmektedir. Ortaklıklar açısından ise sırasıyla bakım yöntemleri, değer öğretimi, sevgi gösterme, kural uygulama, ilgi/özen gösterme, oyunlar oynamada benzerlik gösterdiği tespit edilmiştir. Büyükanne ve anne-babanın çocuğa yaklaşımları kıyaslandığında; disiplin yöntemleri, bakım yöntemleri ve değer öğretimi açısından benzerlik gösterdiği görülmektedir. Farklılıklar açısından ise sırasıyla sınır koyma, ceza verme bakım yöntemleri, ilgi gösterme, anne-babanın ortak tutum sergilemesi, ödüllendirme ve sabır gösterme yönünden farklılaştığı saptanmıştır. Bulgular doğrultusunda büyükanneler ile anne babaların çocuk yetiştirirken benzer tutumlarda bulunduğu ancak büyükannelerin kendi çocuklarını yetiştirirken uygun bulmadıkları yöntemleri torunlarını büyütürken tekrar etmemeye çalıştıkları görülmektedir. Araştırmada, büyükanneler ile ebeveynler arasındaki kuşak farklılığının çatışma alanı olabileceğine dair bulguya rastlanmamıştır.

Although collective trolling poses a growing threat to both individuals and virtual community owners, the information systems (IS) literature lacks a rich theorization of this phenomenon. To address the research gaps, we introduce the concept of we-intention to capture the collective nature of collective trolling in virtual communities. We also integrate the social identity model of deindividuation effects (SIDE) and situational action theory to invoke the sociotechnical perspective in theorizing collective trolling in virtual communities. The objective of this study is to use the sociotechnical perspective to understand the we-intention to participate in collective trolling in virtual communities. We test our proposed model using data gathered from 377 Reddit users. Our moderated mediation analysis elaborates how technical elements (i.e., anonymity of self and anonymity of others) influence the we-intention to participate in collective trolling via individual-based social elements (i.e., perceived online disinhibition and social identity), with an environment-based social element (i.e., the absence of capable guardianship) as a boundary condition. We contribute to research by explaining collective trolling in virtual communities from the group-referent intentional action perspective and sociotechnical perspective. We also offer practical insights into ways to combat collective trolling in virtual communities.

Freelancers in online labor markets often display many skills in their profiles to increase their chances of being hired. However, such behavior may lead to the skills they display straddling multiple categories, that is, “skill spanning.” In this paper, we extend the concept of category spanning into online labor markets in the form of skill spanning and empirically examine (1) how freelancers’ skill spanning affects employers’ hiring decisions for two different types of jobs (low- and high-skill jobs, respectively), and (2) how freelancers’ skill matching moderates the effects of skill spanning on employers’ hiring decisions. Based on a unique dataset of 12,428 high-skill jobs and 19,875 low-skill jobs on a leading online labor platform, we find that freelancers’ skill spanning has different impacts on employers’ hiring decisions for these two job types. Specifically, for high-skill jobs, freelancers’ skill spanning reduces their likelihood of winning contracts; however, for low-skill jobs, freelancers’ skill spanning and their probabilities of winning contracts demonstrate an inverse U-shape relationship. Furthermore, freelancers’ skill matching can moderate the negative effects of skill spanning for high-skill jobs but not for low-skill jobs. Our findings provide guidelines for different stakeholders in online labor markets, including freelancers and platform owners.

The transition to renewable energy requires organizations and governments to formulate and enact new energy policies. This emerging energy era is characterized by higher levels of supply and demand intermittency, which requires information systems to manage the electricity grid. We propose key policy elements for managing intermittency based on information systems to implement digital mirror actions for managing the production, consumption, and transfer of electricity and market mechanisms for maintaining grid equilibrium. This article discusses these and their energy policy implications.

Under modern conditions of development of historical science, the study and analysis of document systems in different historical periods require comprehensive attention. It will help to understand more about the nature of the issue of retrospective functioning of record-keeping relations. Today there is a lack of new research on the historical and regional features of this process. Moreover, the accession of Galicia to the Kingdom of Poland, the creation of the Russian Voivodeship, and hence the introduction of large-scale Polish administrative management, legal system, production, education, culture have not been fully disclosed. Certain differences in the organizational principles of institutional documentation in the Ukrainian lands have not been revealed. The article defines the socio-political status of the population of Galicia, which was determined by belonging to a certain state, namely: nobility, clergy, burghers, peasants, which was reflected in the formation of relevant representative bodies of government at all levels with appropriate regulatory framework, that defined general way of working with documents and managing administrative institutions. At the same time, the article states the fact that despite the accession of Galicia to the Kingdom of Poland forced the indigenous Ukrainian population to get used to the system of government forcibly imposed by the invaders, it did not lose its ethnic identity. It was reflected in the formation of documentary and office-based territorial vocabulary with the preservation of words inherited from the times not only of Galicia-Volyn, but also from ancient Russia. The convening of regular congresses of the nobility and the adoption of relevant documents-decisions not only contributed to the formation of the foundation of aristocratic democracy in the Crown of the Kingdom of Poland, but also accelerated the consolidation of various ethnic and religious groups.
