Published: January 2022

Sustainable development, as a conceptual phrase that encompasses the struggle of endangered humanity for salvation, appeared at the end of the 20th century, ie. at a time when the world is facing a multitude of existential threats posed by man's own negligence towards nature and himself. These threats include the caused natural deformations of the climate and the environment, on the one hand, and mutual destructive national interests of exploitative and existential character (war, terrorist, hegemonic, migrant, etc.), on the other hand. In this context, sustainable development is reduced to the possible development of society in all areas, which can last indefinitely, as well as be replaced by new development that has the same characteristics. That is why the United Nations (UN) and other major world organizations in recent years have agendas, resolutions, conventions and the like. began the struggle for the frontal world introduction of saving sustainable development. However, this largest and most complex world endeavor has just begun, and in order to be successful, it needs to be adequately systematized and organized - which needs to be resolved quickly. In such a current world reality, a very important role is played by political and professional factors that should achieve sustainable development at all levels. There is very little talk about that in the current scientific literature, so it is necessary to elaborate on the scientific-professional factor as more complex than the political one, which is what this scientific paper deals with. For its preparation, an appropriately prepared internal research project was used, in which all ideological factors (problem, subject, goals, hypotheses and research methods) were defined - with a brief overview of Serbia as an example of sustainable development. Accordingly, in this scientific paper, several important scientific information has been identified, especially related to the profile, role and organization of experts in sustainable development, as a scientific and professional factor in that.
Apparent joinder of criminal offenses in the criminal law of Serbia
Authors: Joksić Ivan
Published: January 2022

Apparent joinder of criminal offenses is a legal institute which deviates from the actual or real joinder. It deals with legal situations where one or more criminal acts constitute the substance of several criminal offenses but, for legal and technical reasons, only one criminal offense is considered to have been committed. Following the division of a joinder into ideal and real, where one or several acts of criminal offenses have been taken as a criterion, the apparent joinder is also divided into ideal and real. This practically means that the offender had committed one criminal offense with one criminal act (an apparent ideal joinder) or several acts (an apparent real joinder), regardless whether his/her act or acts constitute the substance of several criminal offenses. Considering the fact that a legal institution of apparent joinder includes an entire catalogue of various legal situations, our legislator stipulates several forms of the apparent ideal as well as the apparent real joinder. They contain modalities of actions constituting the substance of several various criminal offenses. In a criminal theory, the issue of the apparent ideal joinder has occupied the attention of a large number of authors. They have shown an interest in expanding the catalogue of legally defined forms of the apparent joinder of criminal offenses. As a consequence, we have a significantly higher number of forms of the apparent joinder in comparison with the legal framework being used to regulate this institution in our criminal legislature. Therefore, apart from a legal designation, it is necessary to indicate a theoretical designation of both the apparent ideal and apparent real joinders of criminal offenses.
Protection against domestic violence in the meaning of the family Law and the Law on social protection
Authors: Stamenković Goran
Published: January 2022

Domestic violence is a complex, multidisciplinary problem, although at first glance it seems like a very clear, definite, extremely obvious, and recognizable phenomenon. In addition to the concept, characteristics, manifestation, and causes of domestic violence, the paper presents the provisions of the Family Law and the Law on Social Protection, as well as the role and competencies of the Social Services Center regarding protection from domestic violence. The so-called "dark figure" in this area indicates that there is a significant number of unreported cases of domestic violence, and the "silence" of family members can lead to immeasurable consequences. That is why it is necessary to emphasize adequate education, good coordination of institutions, but also influencing the social awareness of people that denying the perceived problem of domestic violence leads nowhere.

Authors: Kostić Sara , Kovačević-Berleković Bojana
Published: January 2022

Socio-demographic characteristics are proven vital in terms of different elements associated with choosing a tourist destination. The tourism industry in the time of Covid-19 has experienced numerous challenges. This research aims to examine the listed elements in the context of the socio-demographic characteristics of respondents. The research results will answer the question if respondents who planned to spend summer holidays abroad in 2020, and that destination was replaced with a domestic destination, statistically significantly differ by some socio-demographic characteristics in comparison to those that planned to travel abroad and succeeded. The results show no differences in social-demographic characteristics and show that respondents who replaced tourist destinations abroad with a domestic ones are more eager to do that again in the future. Following obtained results of the research, the authors point to key conclusions and recommendations.
Napomene o odlikama grafije i ortografije Atonskog prepisa Dušanovog zakonika
Authors: Antić Aleksandra
Published: January 2022

The paper describes the spelling of the consonants j, lj, nj, ć and đ and the groups consisting of the aforementioned consonants and vowels in The Aton Transcription of Dušan's Code, written in the first half of the 15 ͭͪ century. The consonant j has traditionally been marked with the grapheme i. The use of ] and E for marking of the groups [ja] and [je] indicates that the traditions of Raška orthography have been followed. Graphemes e and j have often been used to mark group [je], which is a typical feature of the Resava orthography school. The group ju has mostly been marked with }; there are only few examples with the use of M and ou. The grapheme i has been used for writing the group [ji] while the group [jo] has been written with the graphemes w and O. The examples from the corpus point to three ways of writing the sounds lj and nj (volna, vol`ni, kralq; kon`mi, konq, kw³). The group lja was marked in two ways-with the graphemic groups l] and the group la. When it comes to the group [nja], we noticed that the combination with ] predominated [nja]: kon]. To mark the groups [lje] and [nje] the combinations lE and nE were used. There are few examples of the groups [ljo] and [njo], which point to the use of graphemic groups lo and nw. The graphemic combinations with } were used to indicate the groups [lju] and [nju]. Contrary to the group [lji], which was always marked with li, the group [nji] was marked in three ways: knigou, pomanJi, prqvnQ~. Two different ways of marking the consonant ć are seen in the examples of vlasteli;ikq, vlasteli;i®. The group [ća] has always been marked with k]. The combinations g], d], ga were used to indicate the group [đa]. The groups with E are dominant in marking the groups [će] and [đe]. The only registered example points to the use of kw to mark [ćo]. The groups [ću] and [đu] were almost always written with the help of the graphemic groups k} and g}. More than one solution for writing the group [ći] has been registered: kouki, koukQ, vekQi. The group [đi] is written as kragi. The comparison of The Aton Transcription with The Baranja Transcription indicates a great similarity of these two manuscripts in terms of marking j, lj, nj, ć, đ and the groups consisting of the aforementioned consonants and vowels.
Circumstances in the central areas of old Serbia in the late 18th and early 19th centuries
Authors: Nedeljković Slaviša , Đorđević Miloš , Popović Aleksa
Published: January 2022

Throughout the 18th century, anarchy raged through the Ottoman Empire, the consequences of which directly affected Christian subjects, who felt growing property and legal insecurity. The Turkish central government almost did not exist. Although Porta repeatedly tried to curb anarchy and separatist movements with a series of firmans and berets, little was achieved in that regard. In the years after the Great Migration, the settlement of Arbanasi tribes from the mountainous areas of northern Albania began. Supported by the Ottoman authorities, in the following decades, the Arbanassis turned the central area of Old Serbia into a scene of feudal and tribal anarchy and bloody reckoning with the Serbian Orthodox population. Burdened with numerous taxes and levies, as well as reading, which was often imposed by force by Muslim masters, the Serbian population was increasingly materially declining. The difficult situation was further aggravated by numerous Kachak gangs, bashibozluk and janissaries, who systematically plundered the serbian christian population. The unbearability of such a difficult position will give rise in the first years of the 19th century to the desire for liberation from the centuries-old Turkish rule, which will be manifested in the outbreak of the First Serbian Uprising in 1804 in the Belgrade pashaluq.
The role and importance of teachers in the distance learning system
Authors: Dobrić Tamara , Đurić Igor
Published: January 2022

Distance learning is a planned learning that does not require the physical presence of students and teachers in one place, which means that they are spatially distant from each other. In distance learning, which is organized for both students and adults, the teacher is an indispensable participant. Teachers are expected to follow the innovations and better themselves in accordance with current changes in order to educate students to live in the current moment. A teacher who teaches at a distance should not only have educational, communicative, digital, methodical, and organizational skills but also high digital competence. Teachers` digital competencies are necessary for using modern educational technologies and distance learning. The digital competence enables teachers to work with modern information and communication technologies in order to achieve their goals in the context of their work. It is of great importance that teachers have the ability to search for, gather, and critically analyse information, but also, skills to use multimedia information, the ability to access, search, and use the internet services needed for continuous professional development. The development of teachers` digital competencies today is necessary for the application of digital technologies in the educational process. The paper will discuss distance learning, educating teachers for distance learning as well as developing teachers` digital competencies. The aim of this work is to draw teachers` attention and enable them to realize specific characteristics of distance learning and to gain knowledge in the field of modern educational technologies, to keep improving permanently so as to apply the acquired knowledge in distance learning and therefore improve the educational process itself.
University students' centre for psychological counselling: empirical research and potential importance for the improvement of the quality of student life
Authors: Todorović Dušan , Ranđelović Dušan , Ilić Darinka
Published: January 2022

Counselling psychology addresses the emotional, social, work, school, and physical health concerns people may have at different stages in their lives, focusing on typical life stresses and more severe issues with which people may struggle as individuals and as a part of families, groups, and organizations. The increasing rate of psychological problems and their consequences indicate that student centres that provide psychological assistance have to exist. The pilot project "Psychological counselling centre for students" at the University of Niš is one of the largest and longest running projects of this type among the universities in Serbia. The basic research problem is an attempt to predict the frequency of occurrence of student-related problems regarding: learning and intellectual functioning, emotional relationships, communication, and social relations based on self - concept, quality of family communication and emotional intelligence. The sample consisted of 400 students from University of Niš. A self-concept scale (Bezinović, 1988) was used to measure the self-concepts of adolescents, while (primary) family satisfaction was measured using the Faces IV questionnaire (Olson & Gorrall, 2006). To estimate emotional intelligence, the Emotional Competence Questionnaire was used (Takšić et al., 2006). Almost all the models were obtained via the hierarchical regression analysis, and proved to be statistically significant, so that the percentage of the explained variance ranges from 7.9% when it comes to problems in the sphere of emotional relationships, to 24,8% in the sphere of communication and social relations. This means that the models best functioned precisely when it came to explaining the problem of communication and social functioning among students, even though the percentage of the explained variance of 10,9% in the case of the problem of studying and intellectual functioning is not negligible. The study of potential and significant factors which could have an impact, whether positive or negative, on the mental health of the student population is and should be an imperative for the scientific and professional community.

Published: January 2022

Venous thromboembolism (VTE) is a major complication in all patients with cancer. Compared with the general population, patients with multiple myeloma (MM) have a 9-fold increase in VTE risk, likely because of their malignancy, its treatments, and other additional patient-related factors. In MM, thromboembolism events tend to occur within 6 months of treatment initiation, regardless of treatment regimen; however, the use of immunomodulatory agents such as thalidomide or lenalidomide, especially in combination with dexamethasone or multiagent chemotherapy, is known to create a significant risk for VTE. Currently, official recommendations for VTE prophylaxis in MM outlined in various national guidelines or multidisciplinary society panels are based on expert opinion, because data from randomized controlled trials are scarce. Large studies which have mainly focused on the efficacy of thromboprophylaxis in patients with cancer at higher risk for VTE either had a very low representation of patients with MM, or excluded them all together, limiting our ability to draw evidence-based conclusions on how to effectively protect MM population from VTE. In this brief perspective, we highlight some of the greatest challenges that have hampered the field concerning the availability of high-quality clinical trial data for the formulation of best VTE prophylaxis strategies in patients with newly diagnosed MM, as well as the rationale for the latest updates in the NCCN Guidelines on this topic.

Published: January 2022

Incidentes envolvendo despejo de poluentes em meios hídricos vem se tornando cada vez mais frequentes, tornando importante o estudo de novos métodos a fim de desenvolver estratégias que permitam prever esses episódios e amenizar seus danos à natureza e à vida humana. O presente trabalho tem como objetivo fazer uma comparação entre modelos unidimensionais de difusão e advecção para a dispersão de poluentes usando como exemplo de aplicação o rio Paraibuna, com o propósito de discutir e explorar as características de cada modelo. Para isso, foram utilizados o método GILTT (Generalized Integral Laplace Transform Technique) e o método de Taylor para obter a solução do modelo difusivo e o método de Separação de Variáveis com Transformada de Laplace para a solução do modelo advectivo. São apresentadas simulações de dispersão de poluentes para cada metodologia e os resultados são discutidos e comparados com dados reais observados obtidos em literatura. Os resultados mostram que no modelo advectivo, a nuvem de poluente permanece compacta durante todo o processo, apresentando uma boa aproximação do momento no qual ocorre a concentração máxima em uma posição fixa; enquanto no modelo difusivo, para ambas as soluções, nota-se que a quantidade de poluente é maior em locais próximos a fonte, levando um tempo considerável para sua diluição. Foi possível concluir que cada modelo fornece informações satisfatórias que vão de encontro as expectativas teóricas para a dispersão de poluentes e que a metodologia utilizada foi prática e eficaz para os propósitos deste trabalho.

Authors: Andrade Lazaro Ramom dos Santos , Araújo Sérgio Murilo Santos de , França Kepler Borges , Pearson Howard William
Published: January 2022

A agricultura corresponde ao setor da economia com maior consumo de água, em sua grande maioria, potável. A utilização de águas cinzas, ou residuárias, vem ganhando cada vez mais importância no cenário mundial a medida que as fontes de águas naturais vem sofrendo ações antrópicas, possibilitando sua redução tanto na qualidade como quantidade. Nessa perspectiva, o emprego de tecnologias simples e de baixo custo para tratar os efluentes viabilizam o reuso dessas águas, minimizando os impactos sobre os recursos hídricos. Diante disso, este trabalho tem o objetivo de otimizar um sistema piloto de tratamento de efluentes, utilizando poliestireno como material filtrante. Este material foi escolhido por ter baixa massa específica, baixo custo e ocupar pouca área. O estudo foi desenvolvido no ano de 2019, entre os meses de março a dezembro, na Universidade Federal de Campina Grande, Campus I. Os procedimentos experimentais foram realizados no Laboratório de Referência em Dessalinização (LABDES) pertencente ao Departamento de Engenharia Química. Foi construído e testado um sistema de tratamento de águas residuárias, contendo esferas de poliestireno para remover a cor e a turbidez. Para se alcançar esse objetivo, foram testadas algumas variáveis de entrada como: vazão, diâmetro das esferas de poliestireno e configuração do reator, sendo esta em série ou paralelo. Diante disto, o estudo apresentou a configuração em série como mais significativa, assim como a vazão de 0,5 L/min, e a esfera com 2 mm para a melhor remoção de cor e turbidez dessas águas.
Analysis of functional relationships between the cell quantification variables in the microalgae Chlorella sorokiniana
Authors: Nunes Nathaskia Silva Pereira , Oliveira Igor Gabriel Silva , Ansilago Mônica , Carvalho Emerson Machado de
Published: January 2022

The applications of microalgae are being increasingly explored, as they have a high rate of cell duplication and accumulation of lipids, ranging from 20-50% of their dry weight, reaching up to 80% under appropriate conditions. Their cultivation in artificial conditions has also increased, which has made it important to explore different microalga quantification methods and evaluate its growth kinetics. For algal quantification, it appears that both quantification methods by direct counting in a Neubauer chamber (density) and indirect counting methods such as reading in spectrophotometry (optical density) and dry weight (biomass), are important to validate the results quantification. The objective of this study was to verify the existence of a functional relationship between the variables used to quantify the microalgae Chlorella sorokiniana. For this purpose, linear regression analysis was applied to the variables of cell density, optical density, and dry biomass that were obtained by cultivating the microalgae at different concentrations. Using the equations generated from the regression analysis in Chlorella sorokiniana, it was possible to obtain â€‹â€‹cell density values between 3 and 3.8 Ã— 106 mL-1 and dry biomass values between 0.1 and 4.3 mg.mL-1 from the optical density values acquired using spectrophotometry with extreme precision, and this method was found to be highly feasible.

Published: January 2022

O jambu (Spilanthes oleracea L.) pertence à família Asteraceae, nativa da Amazônia, de clima tropical.  Essa planta é uma hortaliça bastante cultivada e consumida na região Norte do Brasil, principalmente no Pará. Algumas de suas formas de utilização são nos restaurantes de comidas exóticas utilizando a inflorescência de jambu para compor seus pratos diferenciados na gas­tronomia. Entretanto o maior interesse nesta cultura é devido ao seu óleo essencial amplamente utilizado nas indústrias cosméticas e farmacêuticas. Nesta pesquisa, objetivou-se a obtenção e caracterização do óleo essencial de jambu cultivado de modo orgânico e convencional e seu possível efeito fungicida. O óleo essencial de folhas e inflorescências de duas cultivares (Jambuarana e Nazaré) foi obtido pela técnica de 'arraste a vapor d’água', usando um aparelho de Clevenger modificado e submetido, posteriormente, à análise por CG acoplada a um espectrômetro de massas CG-EM, a fim de analisar sua composição química. Além disso, foi testada a atividade antifúngica sobre Aspergillus niger. O óleo de Spilanthes oleracea mostra diferenças entre as cultivares e entre os órgãos estudados, em função de sua fenologia.  O maior potencial antifúngico observado foi obtido de inflorescências da cv. Nazaré orgânica. Esta espécie é promissora produtora de óleos essenciais de alto valor agregado.

Authors: Souza Jamille Silva Rodrigues de , Sarmento Priscila Sanjuan de Medeiros , Pontes Aldo Nascimento , Pontes Altem Nascimento
Published: January 2022

O Programa Municípios Verdes foi criado no estado do Pará no ano de 2011, inspirado na experiência bem-sucedida do município de Paragominas, que adotou procedimentos para a regularização ambiental em resposta à sua inclusão na lista do Ministério do Meio Ambiente. Paragominas foi o primeiro município da Amazônia a sair da lista do desmatamento, recebendo premiações como a de Chico Mendes no ano de 2010, em que são levados em consideração os critérios de participação social, impacto social, ambiental, dentre outros. O presente artigo teve como objetivo fazer um estudo sobre a implantação do Programa Municípios Verdes como política pública para mitigação de degradação ambiental no Município de Paragominas, Pará, na perspectiva dos moradores. Em termos metodológicos, a pesquisa foi quali-quantitativa, bibliográfica e com atividades de campo. A coleta de dados foi realizada por meio de um formulário nos meses de fevereiro e março de 2018, com 60 respondentes. Os resultados indicaram que os problemas de maior gravidade em Paragominas são: contaminação de solos e degradação ambiental, seguidos do uso excessivo de agrotóxicos e os lixões. Em nível intermediário, destacam-se a falta de saneamento básico e poluição da água, bem como, a falta de Educação Ambiental e de arborização. Os problemas de menor gravidade para a amostra são o desmatamento e escassez de água potável. Esses resultados indicam que a implantação do PMV foi importante para conter os problemas ambientais em Paragominas, mas novas ações precisam ser adotadas no sentido de mitigar os impactos ambientais que ainda persistem no município.
Understanding Proximity Mobile Payments Adoption in South Africa: A Perceived Risk Perspective
Authors:   Department of Marketing Management, University of Pretoria, Lynnwood Road, Hatfi eld, Pretoria, South Africa, Eksteen Charlene , Humbani Michael
Published: January 2022

Although existing literature claims that consumers are ready for proximity mobile payments, the reality is that adoption is still low in South Africa. Service providers’ attempts to translate this potential into profi t is hindered by consumers’ perception of risks associated with proximity mobile payments. The purpose of this study was to investigate the perceived risk dimensions as possible inhibitors of proximity mobile payment adoption, as well as to investigate the role of gender diff erences, drawing from the perceived risk and push-pull theories. Using a convenience sample, data was collected from South African smartphone users, from whom 284 valid online surveys were obtained. The standard regression analysis reveals that fi nancial-security and performance risk are predictors of proximity mobile payment adoption, and that product risk is not a signifi cant predictor, at least in the South African context. The fi ndings also reveal that both genders feel more or less the same about the infl uence of risk factors on the adoption of mobile proximity payments, except for performance risk. The results also show that females are more concerned about the performance of proximity mobile payments than males. The study provides tangible insights that service providers and marketers can use to guide application development and communication with consumers. A contribution is also made to the limited empirical research on the infl uence of proximity mobile payment risks on adoption during crisis times.

Published: January 2022

Las enrgías renovables (EERR) es la gran esperanza mundial para contener el cambio climático, pero se observa una gran dificultad en el proceso de transición. Por ello, la Unión Europea (UE) estableció que para 2030 el porcentaje de EERR debería cubrir un 32% del consumo total de energía. En ese contexcto España busca adecuarse para atender a los retos energéticos. Ese estudio analizó el marco regulatorio de las fuentes de EERR en España y sus implicaciones para el desarrollo de esas fuentes. El estudio trata de un análisis de revisión del marco regulatorio de las EERR en España y análisis descriptiva de datos secundarios sobre ese tipo de energía, entre los años de 1997 hasta el período actual. Como resultados se observó que las políticas europeas de EERR de la primera década del siglo XXI también han mostrado sus limitaciones. Se ha hecho evidente que el marco político y económico de su implantación es inestable y fluctuante. Más recientemente, con el nuevo Real Decreto 244/2019, que establece que toda energía consumida de origen renovable estará exenta de cargos y peajes, juega luz al crecimiento de las renovables y posibilidad real de cumplir los objetivos de la UE para 2030.

Compósitos madeira-cimento: um produto sustentável para o Futuro
Authors: Castro Vinicius Gomes de
Published: January 2022

Tijolo, concreto, aço, gesso, o que estes produtos tradicionais de construção possuem em comum? Todos continuam a emitir gás carbônico durante suas vidas úteis. A construção civil é hoje responsável por quase 40% do carbono na nossa atmosfera. Por isso é importante que os produtos que hoje usamos para construir sejam repensados. Compósitos madeira cimento é uma das alternativas promissoras neste sentido. Estes compósitos são formados pela mistura de partículas de madeira, que não só emitem baixo teor de gás carbônico em uso, mas também armazena o carbono durante seu processo de formação enquanto árvore, e cimento, material comum, aceito e de fácil acesso em todo o mundo. A combinação destes produtos geram um compósito com características positivas de ambas as partes, por exemplo, ao mesmo tempo que resistem ao ataque de fungos e cupins, por causa do cimento, são mais leves e elásticos, por causa da madeira. Porém ainda há desafios para a popularização deste material, sendo o principal deles a seletividade da espécie de madeira usada que pode interferir na pega do cimento. Assim, essa obra busca levantar o estado da arte dos estudos sobre esse material para servir de base e inspiração para o desenvolvimento de novas pesquisas e inovações tecnológicas.

Constructing core-shell structures can effectively reduce the surface quenching effect of luminescent materials, which becomes an effective method to enhance upconversion luminescence. In this work, a series of NaLnF4@NaLnF4 (Ln = Y3+, Yb3+, Ho3+) core-shell microcrystals is successfully synthesized based on epitaxial growth technology, thereby enhancing and regulating the upconversion emission of Ho3+ ions. The results of the XRD and SEM indicate that the NaLnF4@NaLnF4 core-shell microcrystal possesses a pure hexagonal-phase crystal structure with a rod-like shape. Meanwhile, it is found that the epitaxial growth direction of the micro-shell is not affected by the crystal characteristics in the core, but determined by the crystal characteristics of the shell. Under 980 nm near-infrared laser excitation, the upconversion luminescence properties of single microrods with different core-shell structures are investigated via a confocal microscope spectroscopy. It is found that in the NaLnF4 micro-crystal, the coated NaYF4 inert shell can also effectively reduce the quenching effect on the surface of the micro-crystal for enhancing upconversion emission. When the Yb3+ ions are introduced into NaYF4 or NaYbF4 active shell that is coated, the Yb3+ ions in the shell can effectively transfer excitation energy to Yb3+ in the core through energy migration, and then establish new energy transfer channels, thereby realizing the Ho3+ ion luminescence enhancement. For NaHoF4@NaYbF4 core-shell microrods, the Yb3+ in the shell can transfer more excitation energy to Ho3+ ions at the adjacent interface for enhancing the overall luminescence intensity, and its higher red-green ratio is mainly due to the cross-relaxation process occurring between the Ho3+ ions at high doping concentration of Ho3+ in the NaHoF4 core. Meanwhile, the luminescence process of the micron core-shell system is further confirmed based on the luminescence characteristics of different structures and the dynamic luminescence process. It can be seen that constructing different micron core-shell structures and introducing sensitizing ions, can not only effectively enhance the luminous intensity of the micron materials, but also adjust the output color. Therefore, this research is an important experimental reference for enhancing the luminous intensity of the micron system and the precise adjustment of luminescence, and can effectively expand the applications of micron crystals in the fields of displays, micron lasers and anti-counterfeiting.

1H MRI maps brain structure and function non-invasively through versatile contrasts that exploit inhomogeneity in tissue micro-environments. Inferring histopathological information from magnetic resonance imaging (MRI) findings, however, remains challenging due to absence of direct links between MRI signals and cellular structures. Here, we show that deep convolutional neural networks, developed using co-registered multi-contrast MRI and histological data of the mouse brain, can estimate histological staining intensity directly from MRI signals at each voxel. The results provide three-dimensional maps of axons and myelin with tissue contrasts that closely mimic target histology and enhanced sensitivity and specificity compared to conventional MRI markers. Furthermore, the relative contribution of each MRI contrast within the networks can be used to optimize multi-contrast MRI acquisition. We anticipate our method to be a starting point for translation of MRI results into easy-to-understand virtual histology for neurobiologists and provide resources for validating novel MRI techniques.

The outcome of an encounter withMycobacterium tuberculosis(Mtb) depends on the pathogen’s ability to adapt to the variable immune pressures exerted by the host. Understanding this interplay has proven difficult, largely because experimentally tractable animal models do not recapitulate the heterogeneity of tuberculosis disease. We leveraged the genetically diverse Collaborative Cross (CC) mouse panel in conjunction with a library ofMtbmutants to create a resource for associating bacterial genetic requirements with host genetics and immunity. We report that CC strains vary dramatically in their susceptibility to infection and produce qualitatively distinct immune states. Global analysis ofMtbtransposon mutant fitness (TnSeq) across the CC panel revealed that many virulence pathways are only required in specific host microenvironments, identifying a large fraction of the pathogen’s genome that has been maintained to ensure fitness in a diverse population. Both immunological and bacterial traits can be associated with genetic variants distributed across the mouse genome, making the CC a unique population for identifying specific host-pathogen genetic interactions that influence pathogenesis.

Background

The hazelnut (Corylus avellana) is still one of the most profitable nut crop species. In recent years, however, there has been growing interest in this species in the form of “fresh nuts” that are picked before falling out of the fruit cover. The aim of this study was to evaluate the effect of storage conditions for hazelnuts protected with biological preparations on selected morphological features of the fruits, their health status and the count of bacteria and fungi colonizing the fruits.

Results

The hazelnuts harvested from the trees protected with a preparation containing Pythium oligandrum and stored for 2 months under the controlled atmosphere conditions and in Xtend® bags (MAP) had the greatest weight and the highest percentage of the kernel. After 3 months of storage, the hazelnuts had reduced commercial value. Only a few hazelnuts displayed symptoms of infectious diseases caused by species of Botrytis and Monilia. The protection applied before the hazelnut harvesting contributed to a multiple increase in the bacterial and yeasts count on the husks and shells of the hazelnuts stored for 3 months. The bacterial count on the nuts stored under the controlled atmosphere (CA, 3%O2:3%CO2, a temperature of 0–1 °C, humidity of 85–95%) and under the controlled atmosphere conditions and in Xtend® bags (MAP) increased significantly. An analysis of the ITS region sequence revealed the presence of bacteria Arthrobacter luteolus and Pantoea agglomerans. A Koch test proved that both non-pathogenic bacteria and pathogenic fungi can cause the browning of the C. avellana leaf under conditions of high humidity. The application of a controlled atmosphere is recommended for a short-term storage of hazelnuts in the husk.

Conclusion

This research showed that 2 months’ storage of hazelnuts under controlled atmosphere conditions and Xtend® bags (MAP) prevented a reduction in the weight of hazelnuts in the husk, without the husk, and of the kernel and prevented the nut separation from the husk. In general, the application of biopreparations for the protection of the hazelnut had a positive effect on the kernel weight and size.

Background

Dental impressions are used to record anatomy of teeth and surrounding oral structures. Impression materials become contaminated with saliva and blood requiring disinfection, which may have negative impact on dimensional stability of materials.

Objective

Comparatively evaluate linear dimensional changes of synthesized Tetra-functional (dimethylsilyl) orthosilicate (TFDMOS) containing Polyvinylsiloxane (PVS) impressions following sodium hypochlorite disinfection.

Methods

Percentage dimensional changes of three commercial PVS (Elite HD Monophase, Extrude and Aquasil Ultra Monophase) and five experimental PVS impression materials were measured. Experimental material contained novel cross-linking agent (TFDMOS) and a non-ionic surfactant (Rhodasurf CET-2) that is Exp-A (without TFDMOS), Exp-B (with TFDMOS), Exp-C (TFDMOS+ 2% Rhodasurf CET-2), Exp-D (TFDMOS+ 2.5% Rhodasurf CET-2) Exp-E (TFDMOS+ 3% Rhodasurf CET-2). Samples were made using rectangular stainless-steel molds (40 × 10 × 3 mm3) and linear dimensional changes were measured using a calibrated travelling microscope at 10× magnification after immersion in distilled water (D.W) and 1% Sodium Hypochlorite solution at two different time intervals i.e., 30 min and 24 h.

Results

Samples immersed in 1% NaOCl showed significant (p < 0.05) dimensional changes after 30 min of immersion. Exp-E showed significantly greater dimensional changes than their control (Exp-A and Exp-B). In distilled water, there were no significant difference among the tested materials. Aquasil exhibited highest expansion (0.06%) in both solutions. At 24 h, among the commercial materials, Extrude had the greatest expansion followed by Aquasil and Elite in DW while Aquasil showed the greatest expansion followed by Extrude and Elite in NaOCl.

Conclusion

Experimental PVS had linear dimensional changes within the ISO 4823; 2015 recommended range. However, extended immersion can negatively affect the linear dimensions.
