Inter-molecular interactions between water and ethanol
Authors: Ma Sijia
Published: March 2023

The structure and properties of alcohol-water mixtures are of great significance in the study of mass transfer theory and industrial applications. When dissolving in water, alcohols form hydrogen bonds with water, further complicating the properties of the binary mixture. The properties of the mixture they form are quite different from those of the corresponding pure substance. However, although ethanol-aqueous solutions have been widely used, the physical and chemical properties of ethanol-aqueous solutions have not been thoroughly explained. In this paper, various physical changes of ethanol and water after dissolution were observed by experiments, and the possible causes of these changes were analyzed from the perspective of molecular dynamics. It is of positive significance to further understand the molecular interaction between ethanol and water in mixtures and the properties of ethanol aqueous solution.

Published: March 2023

Abstract: Background: Quality of life should be a very important issue for doctors, especially in chronic diseases. Currently, the most important matters in the therapeutic process are not only bringing about the relief of certain symptoms of the disease itself, but also improving the patients functioning with respect to such areas as social, physical and self-perception through the disease. The study researched the quality of life in relation to demographic and clinic factors in patients with different psychiatric disorders. Materials and Methods: The Medical Outcomes Study Short Form-36 (SF-36), Hospital Anxiety and Depression Scale (HADS), socio-demographic data questionnaire were delivered to a group of 186 subjects (110 females, 76 males) during outpatient visits or hospitalizations in the Psychiatry Ward of the Hager Multispecialty District Hospital in Tarnowskie Gry. There were 5 groups of patients, who had been diagnosed with different psychiatricdiseases: schizophrenia (22 females and 28 males in mean age 33,410,06), recurrent major depressive disorder (28 females and 18 men, age was 40,6110,64), bipolar disorders (8 woman and 12 men, average age was 41,0910,45), anxiety disorders (26 women and 18 men the age was 33,5810,21) and eating disorders (women only mean age was 26,4342.50). Results: Schizophrenic patients showed significantly better results in health-related quality of life in most domains of SF-36 score and summary scales The Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS) than patients with other psychiatric disorders. The lowest results in SF-36 scale were obtained by recurrent major depressive disorder and eating disorders patients. Importantly, symptoms of depression and anxiety influenced the quality of life in all examined groups. Age, marital status as well as duration of illness were negatively associated with the MCS. The BMI was negatively associated with PCS in schizophrenic patients. In anxiety patients, MCS was negatively influenced by BMI.Conclusions: Active treatment for depressive and anxiety symptoms is recommended to improve quality of life in patients with different psychiatric disorders. Schizophrenic andanxiety patients must not forget that high body weight may be a risk factor of the low quality of life.
Risk assessment in railway traffic planning - assumptions for the method
Authors: Gołębiowski Piotr
Published: March 2023

Every activity, including within the railway system, is subject to risk, i.e., the possibility of uncertain phenomena that may affect it (both positively and negatively). One of the operational subsystems of the Union Railway System is railway traffic. It consists of four processes - the second is traffic planning. This process is also subject to risk. As it directly relates to traffic safety, conducting research and analyzing the risks involved makes sense. This article aims to develop the assumptions for a risk assessment method in railway traffic planning. This method, once created, will be used to carry out a risk assessment of the indicated process from two points of view: the railway undertaking and the infrastructure manager. As a result of the considerations, it was assumed that risk identification would be performed using the risk description principle from the M_o_R methodology. The risk estimation will be adapted to use a probabilistic risk assessment model. This assessment will be performed using the Monte Carlo simulation method, which is strongly recommended for use by the Office of Railway Transport (the national railway safety body).

Authors: SRINIVAS GURRAM , PREETAM V CHINNI , SWATHI B
Published: March 2023

In the present study, effect of different non-antibiotic feed additives either alone or in combination on the performance and cost economics of broiler chickens was investigated. Day-old commercial male broiler chicks (270) were randomly divided into nine treatment groups with six replicates of five birds in each. The dietary groups consisted of control diet, antibiotic (Virginiamycin @ 500 g/ton), probiotic (Protexin @ 500 g/ton), acidifier (Biotronic SE @ 3 kg/ton), prebiotic (Mos @ 500 g/ton) and its combinations with different inclusion rates. The results indicated that mean average body weight gain and feed conversion ratio of broilers were significantly influenced by addition of probiotic, prebiotic and acidifier either alone or in combination during prestarter, starter and finisher phases without showing any significant effect on average feed intake. Supplementation of dietary feed additives (except probiotic + acidifier) fed group yielded higher returns over feed cost compared to control and antibiotic fed groups. The highest return per bird was recorded with acidifier followed by probiotic + Mos groups.

Published: March 2023

Worldwide, potato is consumed in different forms from cooked to fry, and accordingly the standard cultivars and its production are met. In recent times, the demand for smaller or baby potatoes (Solanum tuberosum L.) with a target size of 20-40 mm in diameter is increasing to meet the culinary market. The production method of baby potato is markedly different from ware potatoes, as are harvested prematurely that led to greater yield reduction per unit area. Hence, a holistic approach is imperative to minimise the yield loss as no single dependent factor operates independently. Therefore, the commercially leading potato cultivars (K. Khyati, K. Himsona, K. Pukhraj and K. Pushkar) were evaluated in AICRP (Potato) under contrasting growing environments for two years to understand the interaction effect of location, cultivars and harvesting time together on yield components. The results revealed a highly significant difference for all three main effects for the entire tuber size production indicated an existence of heterogenity among growing environments and cultivars. The interaction effects location*cultivar and cultivar *harvesting time exhibited a highly significant difference for small (<20 mm), medium (20-40 mm) and large size tuber yield (>40 mm), total yield and tuber dry matter content indicated their strong influence on these traits. The growing location Chinndwara registered substantially greater efficiency by accounting 145, 115, 61 and 97% for small, medium, large size tubers and total tuber yield, respectively. The delay in harvesting time (>75DAP) reduced the per cent of small and medium size tubers and their yield. Although, cv. K. Himsona had the greatest per cent of small and medium size tubers suitable for baby potatoes, the yield of this group was found greatest in cv. K. Khyati and at par with K. Pukhraj across locations, hence can be recommended for baby potato production under tropical conditions.

Theorizing the Developmental Rwandan Path and Its Relationship with China
Authors: He Meicheng
Published: March 2023

When the industrialized countries stepped into modernization, similar ideas were voiced in the South. Drawn to the emerging Asian economies and modernized ‘South’ precedents, Rwanda began to explore a fitted way of rehabilitating and recovering from the continuing crisis under its decolonization circumstance. During this volte-face period, China, as a rising power, engaged in Rwandan practices on economic development and transition. This paper poses the related hypotheses about Chinese transformative models’ transferability and the two countries moving towards within the globalization dialogue. Methodologically, this paper reveals the causal links between Rwanda's pattern of modernization and China’s involvement through the perspective of developmental modernization theory and the semi-qualitative method of studies. Based on the statistical analyses and theoretical research, the intrinsic distinction between these two economies is noted. Furthermore, the thesis also elaborates on the importance of a better-balanced development of North, South, and East, which could have beneficial consequences as a whole.

Zhang Jiarui’s three films: When Ruoma Was Seventeen (2003), Huoyao Bride in Shangrila (2005) and Red River (2009), are often referred as the ‘Yunnan Trilogy’. Because they are based on the Yunnan minority and all three films were directed by Zhang Jiarui and written by Meng Jiazong. All these three films were produced in the first decade of the 21st century. To a certain extent they have a more stable pattern of change in terms of the director’s personal artistic experience. Reflects the value turn in the creator’s creative philosophy, I consider the three films as a system, examining their changes over from the perspectives of ethnicity and commerciality. This individual phenomenon of the creators may serve as a symptom of the changes in minority films in the new century of China.

It is based on the effort to collect field data; follow the development and refinement through the systematic data analysis, and the final result can test existing theories or develop a new theory. Therefore, it constructs hypotheses and theories by the continuous collection and analysis of data. It is established for the first time in 1967 by two American sociologists Barney Galland Glaser and Anselm Leonard Strauss. Since the starting, it has taken on different iterations, and evolved a number of variants, such as classic grounded theory, Straussian grounded theory, constructivist grounded theory, and feminist grounded theory. New grounded theory researchers face difficulties to understand how to operate and apply families of grounded theory concepts and methods properly. This study has planned to provide an overview of families of grounded theory with the proper explanation for them. In this study an attempt has been taken to provide an up-to-date research framework of a grounded theory and its variants.
Gamma Irradiation as a Possible Phytosanitary Treatment against the Greater Wax Moth, Galleria mellonella, Mature Larvae
Authors: Mansour M. , Ismaeil I.
Published: March 2023

Larvae of greater wax moth, Galleria mellonella L., can be a devastating pest of honeybee combs in storage. Current control measures may not be adequate or with some drawbacks. Treatment with ionizing radiation could be a possible alternative. Determining the dose, however, requires a detailed study on the radiosensitivity of this stage.

In this study, the sensitivity of the greater wax moth mature larvae to ionizing radiation was examined. Larvae were exposed to gamma radiation dosages (50 to 400 Gy) and effects on rate of development, pupation and pupal eclosion (adult emergence) were investigated. In addition, large scale confirmatory tests were conducted to validate treatment efficacy at statistical confidence levels needed for phytosanitary (quarantine and disinfestations) security. Results showed that radiation sensitivity of G. mellonella mature larvae increased, as expected, with increasing radiation dose. The magnitude of the effect, however, depends on the criterion used for measuring effectiveness. Both pupation and pupal eclosion were significantly affected at 50 Gy dose and no emergence was recorded at 300 Gy. Results of large scale confirmatory trials (>30,000 mature larvae) supported the results of the small scale studies. According to probit analysis of dose mortality data for pupation and pupal eclosion, the LD99 for preventing development of mature larvae to pupae and adults is 576 and 318 Gy, respectively. In addition, the developmental rate of mature larvae to adults was negatively affected. This suggests that a dose of 250 Gy may be adequate for disinfesting honeybee products infested with greater wax moth larvae.

Biodegradation of Plastic Waste
Authors:   Institute of Chemistry, College of Arts and Sciences, University of the Philippines Los Baños, del Rosario Ernesto ,   National Academy of Science and Technology Philippines
Published: March 2023

Plastic waste has greatly contributed to water and land pollution worldwide and marine plastic waste has caused havoc on numerous biological species. Most plastics are fossil-based and cannot be fully degraded by microorganisms. Bio-based plastics derived from biomass, such as starch or cellulose, can be generally degraded into CO2 and microbial biomass. Recent scientific studies have shown that several pro-degradant additives did not perform, as claimed by plastic processors, under standard biodegradation conditions. Life cycle assessment studies in the United States and Canada confirm that the standard polyethylene grocery bag has significantly lower environmental impacts than a 30% recycled content paper bag. Major factors that differentiate cradle-to-grave impacts of plastics and alternative packaging materials include: (a) less weight of plastic material required to perform same packaging function, (b) lower water consumption per kg of plastics compared to alternatives, (d) no methane releases for land-filled plastics and (e) higher energy credits for plastics disposed via waste-to-energy combustion. A Dutch study showed that substitution of fossil-based plastics by bio-based polymers generally leads to lower non-renewable energy use and reduced greenhouse gas emission. Research at the University of the Philippines (UP) deals with the utilization of agricultural by-products, such as chitin and cellulose, to make bioplastic film for packaging. Nanoclay was also incorporated to produce a nano-composite polymer. Plastic degrading microorganisms have been isolated by UP researchers from local sources including plant root nodules, alkaline spring and soil samples. The following policies regarding plastic products are being recommended under Philippine conditions: (a) government incentives for processors/manufacturers of biodegradable plastic products, (b) restricted importation and sale of non-biodegradable, esp. single-use, plastic products, and (c) funding and logistical support for R & D on commercial additives for plastic biodegradation, local production of bioplastics and isolation of plastic-degrading microorganisms.
Documenting Outdoor Simulated Scenes with Photogrammetry

In both traditional and forensic archaeology, the thorough documentation of context is essential to a proper excavation or recovery, as the processing of archaeological sites and forensic scenes is an inherently destructive process. Over the past few decades, close-range photogrammetry (CRP) has become increasingly utilized by archaeologists to digitally record their excavations. However, CRP has not been employed regularly during outdoor forensic archaeological scene recoveries, and therefore protocols are not well defined for this context. One important consideration when employing CRP is the impact of natural lighting conditions. Light is an important variable when recording scenes using CRP because the quality of light can affect the visual quality of the model and imagery. In particular, shadows from the photographer’s body, trees, and other structures are unavoidable when collecting images around the perimeter of scenes, a requirement of photogrammetry data collection. Therefore, the purpose of the present study was to determine whether implementing light correction tools would improve the three-dimensional model imagery. Two mock forensic scenes with different lighting conditions were photographed four times each in order to test the application of light correction tools, including a large tarp and artificial lights, for mitigating harsh lighting conditions. The results demonstrate that a tarp is a viable light correction tool that can improve the visual quality of the final models by eliminating lighting inconsistencies in both open and wooded environments. Based on these results, improved guidelines for the application of CRP to outdoor forensic archaeological scenes are presented.

The present research aimed to investigate the state of knowledge regarding the social representations of teachers about students with Autism Spectrum Disorder (ASD), based on stricto sensu productions published in Brazil between 2005 and 2021. The methodological procedure used in this literature review was a systematic survey of dissertations and theses regarding the social representations of professors about students with ASD in the Brazilian Digital Library of Theses and Dissertations (BDTD), acronym in Brazilian Portuguese) and Catalog of Dissertation and Theses of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) databases. After applying the inclusion and exclusion criteria, six works were selected, of which five dissertations and one thesis, to compose the analysis. As a result, we identified that most professors are stucked in social representations marked by prejudice and stereotypes. Therefore, it is necessary a broad and continuous clarification of the potential of these students in order to attitudinal changes may occur. We conclude that it is extremely important to carry out further research and studies that approach the theme of social representations and ASD in the academic environment, based on the scarce literature on the subject.
GOVERNANDO OS CORPOS E EMPRESARIANDO A VIDA
Authors: Manfré Ademir Henrique
Published: March 2023

This paper submitted to the Colloquium Humanarum Journal deals with the Project of Life, self-management and the culture of entrepreneurship. Our general objective is to analyze how the Project of Life – as a transversal curricular component – is associated with the culture of entrepreneurship. According to this culture, the Project of Life promises to develop the individuals in multiple dimensions, motivating them to solve problems and make decisions to achieve goals and accomplish professional fulfillment. When associated to the Project of Life, such culture imposes business devices – like competitiveness, performance and productivity – to the educational scope, submitting the training processes to a new governmentality. From that, we raise the following question: What have we made of ourselves under the control forms of life? We believe that the academic debate on the Project of Life is grounded in principles from the neoliberal market, prioritizing the formation of economically productive individuals, whose are, however, politically submissive and docile. Thus, we intend to discuss the role played by entrepreneurial pedagogical rationality in directing the forms of self-government. To develop our criticism, we adopt an analytical standpoint from Foucault's thoughts, which emerges as a theoretical framework capable of presenting the limits of neoliberal devices that place Education in the guidelines of productivity and effectiveness.
As maratonas e as paisagens na Pandemia do coronavírus:
Authors: Couto Tatiana , Freitas Ricardo
Published: March 2023

Nesse artigo analisamos como as empresas de corrida desenvolveram suas atividades durante a pandemia em 2020. Com a maioria dos eventos cancelados no mundo inteiro para evitar aglomerações sociais, algumas maratonas internacionais ocorreram no período pandêmico usando aplicativos ou DVDs . Com o Coronavírus, a Maratona do Rio realiza a competição, explorando o branding de cidade nas medalhas do evento. Nesta pesquisa, são estudados os imaginários de pandemia, cartões postais, mercadorias visuais e paisagens virtuais. Entende-se que esse novo modelo estimula o consumo da cidade, mesmo em um momento de crise mundial. O quadro teórico está apoiado em autores das ciências da comunicação e das ciências sociais como Kavaratzis, Canevacci, Vainer, Augé, Perrota, Tiburtino e Kunsch.
As gambiarras na pandemia:
Authors: Gonçalves Italo Vinicius , Paes Fabio Amaral de Oliveira
Published: March 2023

Gambiarras como táticas subversivas, saberes corporificados, agenciamentos distribuídos e afetos ordinários. Nossa intenção é refletir sobre as gambiarras em período pandêmico, produzidas como uma estratégia de cuidado preventivo à Covid-19. Ao pensá-las por meio do conceito de “texto verbovisual” (ABRIL, 2007), mobilizamos as gambiarras enquanto objetos que promovem redes textuais, tecnologias que são vistas e, ao mesmo tempo, nos olham de volta. Num primeiro momento, discutiremos como tais objetos podem ser vistos enquanto tecnologias que desafiam os operadores lógicos da colonialidade, da modernidade e do capitalismo. Em seguida, usando estudos de caso, pensaremos nas gambiarras em suas relações à própria conformação da pandemia da Covid-19, especialmente em contexto brasileiro.
As estratégias de comunicação da Uber:
Authors: Bertoni Anaís
Published: March 2023

O artigo trata sobre as estratégias de comunicação da Uber: a midiatização da inovação e a conjuntura de risco/Covid-19. Examinamos a circulação de sentidos das estratégias de comunicação da Uber a partir de duas matrizes interacionais: a primeira, apresentando as estratégias de comunicação utilizadas por essa organização durante a implantação de sua plataforma de mobilidade no Brasil; a segunda, permeada pelos discursos da pandemia. A pesquisa se desenvolve a partir de um estudo de caso midiatizado, indicando que a Uber acopla estratégias de ambas as matrizes interacionais, que se interpenetram e geram uma terceira matriz interacional, que oferta inovação e segurança por meio de gramáticas, contratos e operações que circulam via circuitos interacionais.
Articulações conceituais entre reputação, marca, imagem e identidade na construção de sentidos
Authors: Barroca Sandra
Published: March 2023

O presente estudo busca trabalhar os conceitos de marca, identidade, imagem e reputação, estabelecendo uma articulação entre a Teoria de Comunicação, tomando como preceito basilar os contratos de leitura (Verón, 1985), com a comunicação organizacional, na perspectiva de compreender o entrelaçamento entre o que a organização projeta em seus públicos, o que eles realmente percebem e como se constroem os sentidos a partir dos processos de interação.
O contemporâneo na Periferia Viva:
Authors: Souza Ives Teixeira
Published: March 2023

Este artigo apresenta hipótese sobre o que seria o contemporâneo em Belo Horizonte durante a pandemia de Covid-19. Para isso, propõe-se uma análise sobre comunicação estratégica a partir da Periferia Viva, uma rede de articulação formada por uma centena de coletivos que teve como objetivo minimizar as consequências sociais da pandemia. A análise faz emergir tensionamentos sobre a política temporal de Belo Horizonte, de modo a possibilitar a conclusão que a Periferia Viva atuou a partir de uma comunicação estratégica com e pelo cotidiano de moradores de territórios periféricos da cidade, de modo a incluí-los em um mesmo contemporâneo, o que contribuiu para compor uma das permanências de Belo Horizonte: sua modernidade.
