Abstract The experiment was carried out on mango cv. Dusehri to investigate the effect of N, P and K fertilizers on vegetative, reproductive growth, yield and fruit quality. Eight different fertilizer combinations such as T1 (control), T2 (N), T3 (P), T4 (K), T5 (NP), T6 (NK), T7 (PK) and T8 (NPK) were used. Individual or combine fertilizer application of N (1000 g), P (750 g) and K (750 g) were applied during growing season in February and August. All the treatments significantly influenced on vegetative growth, flowering, fruiting, yield and other physiochemical attributes of mango as compared to control. Least effect was observed with individual fertilizer application while combine fertilizer treatments enhanced most of the investigated parameters. Especially, qualitative traits showed non-significant differences between treated and untreated mango trees. However, among the different treatments T8 (NPK) showed significance for fruiting aspects such as maximum size of growth flushes (177.51 mm), total number of panicles/tree (845), total number of flowers/panicle (974), sex ratio (69.18%), fruit retention (13.85%), total number of fruits/tree (379), yield (82 kg/tree), fruit weight (197.5 g), pulp weight (135.5 g) and physiochemical parameters namely TSS (24.53), Vit. C (57.63 mg/100 mL) and total sugar (20.84%). In general, combine application of NPK (T8) were the most effective in enhancing fruiting aspects, yield, physiochemical characteristics as well as improved fruit quality of mango trees.

Published: March 2021

ABSTRACT The understanding of factors determining species geographic distribution is a fundamental aim of ecology. We investigated the environmental niche for three Myrtaceae species in the Brazilian Subtropical Atlantic Forest (BSAF), part of a global conservation hotspot. Based on a literature review, we selected one representative Myrtaceae species in three important forest types in this region: Evergreen Rain Forest (coastal plains and associated mountains ranges); Araucaria Forest, and Seasonal Deciduous Forest (continental upland areas). Geographical coordinates of their distribution were obtained from the BIEN database. As explanatory variables, we considered altitude, climate, cloud cover, and soil classes. We summarized the environmental space occupied by each pair of species using Principal Components Analysis, determined niche overlaps, and applied statistical tests to verify niche equivalences and similarities. The selected species in Evergreen Rain Forest, Araucaria Forest, and Seasonal Deciduous Forest were Myrcia splendens (Sw.) DC., Myrcia guianensis (Aubl.) DC., and Campomanesia xanthocarpa O.Berg., respectively. C. xanthocarpa showed a more restricted geographic distribution than the two Myrcia species that occur from central America to southern Brazil. Species’ geographic distribution were fundamentally determined by temperature and rainfall regimes. Only C. xanthocarpa and M. guianensis, from uplands forest formations, showed environmental niche equivalence. In conclusion, we found that both species of Myrcia showed high climatic niche amplitudes occurring throughout the climatic gradient, while C. xanthocarpa was more subtropical, distributed mostly in the south and southeast of Brazil.

ABSTRACT The understanding of the relationship between the properties of wood and charcoal makes it possible to improve the production of charcoal. Therefore, the random forest algorithm was used in this study to analyze the influence of eucalyptus wood properties on the quality of charcoal as well as the accuracy of the predicted values concerning the results estimated by support vector regression and multiple linear regression. Six properties of wood and six properties of charcoal obtained from the hybrid Eucalyptus grandis x Eucalyptus urophylla and from twelve clones of Corymbia torelliana x Corymbia critriodora at the age of seven were measured. In the analysis, the measure of mean decrease in node impurity (residual sum of squares) calculated with the random forest and the copula correlation was used to evaluate the relationship between properties of wood and charcoal. The random forest was compared to the support vector regression and multiple linear regression through the coefficient of determination, linear correlation between observed and predicted values, mean absolute error and root mean squared error. The accuracy of the random forest was greater than that obtained with the support vector regression and multiple linear regression, mainly in terms of the coefficient of determination and the linear correlation between observed and predicted values. The yield and quality of the charcoal produced from clones were mainly influenced by the holocellulose content, heartwood/sapwood ratio, and basic wood density. The apparent relative density of charcoal was the variable in which the random forest algorithm reached the best level of explanation of the variability as a function of the properties of wood, while the minor error was observed for the fixed carbon content.

Authors: Novaes Marcel
Published: March 2021

Neste artigo apresento uma introdução ao problema do caos quântico, ou seja, da caracterização e do tratamento de sistemas quânticos cujo análogo clássico tem dinâmica caótica. Duas das principais abordagens a esse problema são discutidas: uma delas é estatística, fazendo uso de matrizes aleatórias, enquanto a outra é baseada na aproximação semiclássica. Resultados obtidos por meio dessas abordagens são mencionados para sistemas fechados (funções de correlação espectral), para transporte (momentos como condutância e ruído de disparo) e para ressonâncias (lei de Weyl fractal e funções de onda fractais).

A física estatística da turbulência
Authors: Moriconi L. , Pereira R.M.
Published: March 2021

Realizamos um sobrevoo abrangente sobre a teoria estatística da turbulência, com a preocupação de embasá-la em noções importantes e consolidadas da dinâmica de fluidos, antes de nos aprofundarmos em discussões de modelos mais específicos, sujeitos a debates contemporâneos. A complexidade da turbulência traduz-se, na chamada abordagem estrutural, como o desafio de compreender, a partir da dinâmica de tubos de vorticidade, o transporte de energia das grandes para as pequenas escalas do escoamento, no limite singular de viscosidade nula. Propriedades estatísticas da cascata de energia, como o fenômeno da intermitência, são modeladas por meio de narrativas aparentemente diversas, associadas a processos estocásticos multiplicativos e, alternativamente, à formulação multifractal do espectro de singularidades do campo de velocidade turbulento. A síntese, fundamentação de primeiros princípios e integração dessas duas visões de modelagem à abordagem estrutural forma o corpo essencial das dificuldades teóricas atuais da turbulência.

Published: March 2021

O córtex cerebral apresenta padrões específicos de atividade espontânea produzidos endogenamente. Esses estados são caracterizados com relação ao grau de sincronia da atividade coletiva dos neurônios e ao nível de irregularidade dos disparos de potenciais de ação dos neurônios individuais. Um problema colocado à neurociência teórica é como modelar a emergência de estados espontâneos síncronos e assíncronos a partir de uma mesma rede de neurônios de disparos. Neste artigo, três modelos que oferecem solução para esse problema são revistos. Os modelos utilizam neurônios de disparo da classe conhecida como integra-e-dispara e consideram diferentes estruturas de rede e dinâmicas sinápticas. Mecanismos adotados pelos modelos, como balanço entre excitação e inibição e adaptação dependente dos disparos, são discutidos e contextualizados. Em paralelo, este artigo apresenta alguns conceitos utilizados na modelagem de neurônios e sinapses, oferecendo uma rápida introdução à neurociência teórica.
O problema Fermi-Pasta-Ulam-Tsingou: Equiparticão de energia vista através de simulações computacionais
Authors: Lucero Davi de Mello , Pinheiro Moreira Pedro Augusto Franco
Published: March 2021

Equipartição e conservação de energia são conceitos difíceis de serem ilustrados em sala de aula. Com essa finalidade, implementamos dois experimentos computacionais do problema Fermi-Pasta-Ulam-Tsigou. Nos experimentos, há uma situação na qual acontece a equipartição de energia e outro em que ela não se realiza. A segunda situação levou ao conhecido paradoxo de Fermi-Pasta-Ulam-Tsigou com grandes implicações para o desenvolvimento da Física. Os experimentos são realizados através de uma implementação numérica “feita em casa” e outra através de uma ferramenta computacional disponível na internet e bastante utilizada pela comunidade científica. As implementações são acompanhadas de uma análise matemática, utilizando-se modos normais.
Neoliberalização dos Serviços Públicos: o papel do BNDES no Saneamento Básico pós-2000
Authors: Werner Deborah , Hirt Carla
Published: March 2021

Resumo O artigo analisa o papel do Banco Nacional de Desenvolvimento Econômico e Social (BNDES) na provisão de saneamento básico no Brasil, de modo a compreendê-lo no âmbito do processo de neoliberalização em curso no país desde a década de 1990. A partir da compreensão das rodadas regulatórias no setor de saneamento básico no Brasil, analisou-se a atuação do banco nas operações de crédito ao setor entre 2002-2018, assim como seu papel na estruturação de projetos de concessão e privatização, pós-2016. Analisar os contratos de financiamento do BNDES e sua atuação na modelagem de projetos de privatização, concessão e parcerias público-privadas observando os novos arranjos regulatórios e institucionais, permite compreender a relação do Banco com os entes federados na prestação de serviços públicos de saneamento e os novos espaços de Estado que emergem do processo de neoliberalização. O processo de desestatização do setor de saneamento básico em curso no Brasil se expressa na atuação do banco, seja pelo perfil das empresas tomadoras de empréstimo - empresas privadas e de economia mista com capital aberto -, seja ao se configurar enquanto think tank e estruturador de modelos de privatizações e concessões do setor de saneamento básico no Brasil.

Published: March 2021

O presente artigo analisa os perfis raciais e de gênero representados em duas décadas de cinema brasileiro. O objetivo é contribuir com os debates das ciências sociais sobre desigualdades e com a crítica feminista interseccional, a partir da apreensão de como minorias políticas e grupos dominantes são inseridos nas narrativas formuladas pela indústria audiovisual nacional. Para tal, em primeiro lugar, construímos uma base de dados com os filmes de maior público entre os anos de 1995 e 2015, de acordo com informações disponíveis no Observatório Brasileiro do Cinema e do Audiovisual (OCA-ANCINE). Em seguida, observamos os longas-metragens e classificamos diversas características de 6.450 personagens que obtiveram alguma relevância no enredo das tramas, considerados dois critérios: nomeação ou participação em diálogos. Os resultados permitem indicar padrões discriminatórios de inclusão nas narrativas, que afetam principalmente a população preta e parda.
Word Image as a Cultural Sign in Language, art and Intellectual Journalism (on «Ontology of the Poetic Word Art and Ostrannenye» by M.L. Novikova)
Authors: Valentinova Olga
Published: March 2021

With the development of information technology, the influence of mass-media on the active processes in the language and society is steadily increasing. In this context, the problem of forming high professional culture of journalistic community, which involves working knowledge of information culture, linguistic culture and creative potential of the native language, is essential. Unlike an artist who does not invent images, but thinks in them, a journalist uses language imagery rationally, but not only a means of persuasion aimed mainly at manipulation. Intelligent journalism uses the image as an economical tool of expressing a complex idea, especially when logical thinking is ineffective. The monograph «Ontology of the Poetic Word Art and Ostrannenye» by M.L. Novikova explores imagery as a universal creative principle that enables one to see essential things, previously unnoticed, while conceptualizing the reality. This principle of creation, which features one mechanism, but different functions, works in the language, in the Arts - in oral lore, plastic and synthetic arts, and in intellectual journalism. The book will be of great interest for journalists. It allows readers to see the mechanism of forming the imagery and evaluate and master the creative word as both a tool for constructing new meanings that de-automatize perception, and a conductor of public attitudes, the latter being a special form of peoples interaction, a conceptual space that reflects the world view of a person and society in a particular period of time.

Authors: Abbad Eman Al , Alakhras Fadi
Published: March 2021

Sorption of Acid Red 1 (AR1) from aqueous solutions utilizing low-cost sorbent material; (chitosan-iso-vanillin) is studied under batch conditions. The remaining concentrations of the azo dye are measured at λmax = 546 nm by UV spectrophotometric method. Langmuir data reveal that the maximum removal capacity was 555.556 mg/g at pH 3. Freundlich isotherm represents the best fitting model on the removal of AR1 using chemically modified chitosan verifying the sorption takes place on heterogeneous surfaces with multilayer adsorption. Kinetic studies of the sorption process revealed that intraparticle diffusion is not only the rate-determining step but also a chemical reaction takes place as well. The results indicate that high sorption rapidness with almost 90% achieved within 90 min. Thermodynamic investigations suggest that the process favours an exothermic nature. The polymer utilized in the present study is being considered as a feasible sorbent material for the removal of AR1 from waste effluent.
Managing the Interference for Down-Link in LTE Using Fractional Frequency Reuse
Authors: Ibrahim Ahmed , Al-Awamry A.Al-Awamry , Mohra Ashraf Shawky
Published: March 2021

Long Term Evolution has developed a new radio technology called femtocell or Femto Base station, which is well-suited to improve cellular network capacity and mobile coverage to indoor user's areas. Providing additional capacity and coverage expansion through FBSs could lead to large interference in a cellular radio communication network. In this paper, we proposed an efficient resource allocation scheme based on Fraction Frequency Reuse (FFR) for interference mitigation, where the entire spectrum is shared among network entities. FFR mechanism aims to reduce co-tier and cross-tier downlink interferences by allocating non-overlapping sets of bands to the user equipment at different geographic locations. The main purpose of this work is to compare two main types of FFR schemes, respectively, Strict FFR and Soft Frequency Reuse with the proposed scheme. The three types of FFR schemes were explained and evaluated with Monte-Carlo simulation based on some performance metrics, namely, sum-rate, spectral efficiency, and outage probability. Simulation results showed that the impacts of the proposed scheme are significantly high in comparison with two other methods. The proposed scheme proved to enhance spectral efficiency, reduced the outage probability, and increased the sum rate for all the users.

Authors: Cáseda Teresa Jesús Fernando
Published: March 2021

Este estudio, tras describir las diferentes atribuciones que se han hecho sobre la autoría del Libro de Buen Amor, se decanta por Juan Ruiz de Cisneros por una serie de razones de carácter biográfico y literario. Aporta, a este respecto, diversos documentos que se hallan en los archivos históricos y apunta el origen de algunos episodios de la obra vinculados con su vida (D Melón y Dª Endrina, Dª Garoza, Urraca, D. Simio, etc.). Analiza la composición de “Cruz cruzada, panadera” y descubre la identidad de los aludidos (Fernán García Duque Estrada y Dª María de Noriega), dos personas que fueron vecinas, en tierras de Palencia, de Juan Ruiz de Cisneros. Este poema fue elaborado siguiendo la iconografía presente en el escudo de los Noriega. Y solo alguien como Juan Ruiz de Cisneros pudo elaborarlo, convirtiéndose su autoría del poema, por tanto, en una prueba más sobre su escritura de la obra.

Published: March 2021

Pencabulan adalah semua perbuatan yang berkenaan dengan kehidupan di bidang seksual yang melanggar kesusilaan (kesopanan). Kitab Undang-Undang Hukum Pidana menggolongkan tindak pidana pencabulan kedalam tindak pidana kesusilaan. Tindak pidana pencabulan saat ini banyak terjadi dan sangat memperhatinkan. Anak yang melakukan tindak pidana sudah selayaknya jika diberikan sanksi yang disesuaikan dengan peraturan yang berlaku.Tujuan penelitian yang dilakukan penulis ini untuk mengetahui bagaimana penerapan sanksi pidana terhadap anak sebagai pelaku tindak pidana pencabulan. Jenis penelitian yang digunakan dalam penulisan ini menggunakan jenis penelitian normatif, yaitu menggunakan bahan kepustakaan, baik itu bahan primer, sekunder maupun tersier. Hasil penelitian menjelaskan bahwa upaya diversi tidak dapat dilakukan terhadap anak sebagai pelaku tindak pidana pencabulan. Sesuai dengan aturan dalam Pasal 7 ayat (2) Undang-undang Nomor 11 Tahun 2012 Tentang  Sistem Peradilan Pidana Anak, syarat agar dapat dilakukan diversi hanya terhadap tindak pidana dengan ancaman pidana penjara dibawah tujuh tahun dan tindak pidana tersebut bukanlah pengulangan tindak pidana. Hal tersebut jelas tidak dapat diterapkan dalam tindak pidana pencabulan, karena tindak pidana pencabulan diancam dengan pidana penjara paling lama lima belas tahun

Relevance. Pumpkin is one of the most important source of carotenoids for humans: β- and α-carotene, lutein and zeaxanthin playing a fundamental role in providing twilight and color vision accordingly.

Results. Investigation of pumpkin carotenoid composition, Konfetka variety, revealed for the first time that this cultivar is the only one containing exclusively lutein in pulp with lutein and zeaxanthin in peel and lutein, zeaxanthin and β-carotene in placenta. Lutein concentration in pulp reached 11 mg/100 g, peel – 41.3/100 g, placenta – 51.2 mg/100 g. Zeaxanthin was absent in pulp and reached 28.3 mg/100 g in peel, and 10 mg/100 g in placenta. β-Carotene was detected only in placenta where its concentration was as much as 94.7 mg/100 g. The results indicate great prospects of ‘Konfetka’ components utilization (pulp, peel, placenta) in food industry, production of baby food and biologically active food additives, containing lutein and zeaxanthin.

Relevance. Jerusalem artichoke is a culture that has recently received a lot of attention. It is used to prepare highly effective medicines, fruit and vegetable drinks and purees, and is also used in cooking. The issue of preserving Jerusalem artichoke tubers as a raw material source, a promising direction in the technology of functional products. The purpose of the research is to determine the influence of temperature storage regimes on the preservation of consumer qualities of Jerusalem artichoke tubers.

Materials and methods. The object of research is Jerusalem artichoke tubers (Helianthus tuberosus L.). Plants were grown in the Perm region of the Perm kray. Tubers before being stored were sorted, washed, dried and placed in polymer bags. The test samples were stored at three temperature regime: -22…-18°C, 0…4 and 18…22°C for 3 months. Samples were taken every 30 days. The quality was assessed by organoleptic parameters, dry matter content, total sugar, inulin and vitamin C. Construction of models for predicting the quality indicators of Jerusalem artichoke was carried out on the basis of structural relationships with storage conditions, which were established using two approaches: correlation and information-logical.

Results. Organoleptic parameters of tubers of the studied samples met the requirements of GOST 32790-2014. The mass fraction of total sugar and vitamin C at 18…22°C decreased relative to the initial content by 10.8 and 57.8%. Storage of tubers is accompanied by a decrease in inulin, and after three months, its mass fraction was lower than the original by 61.9 %. Using correlation analysis, linear structural relationships between quality indicators and storage conditions were established, according to which the content of carbohydrates and vitamin C primarily depends on the temperature regime (r=-0.8-0.4), and secondly – on the storage conditions term (r =-0,3-0,3). The use of the information-logical method allowed us to confirm the established correlation relations. The obtained adequate models for predicting the level of quality characteristics of tubers, depending on the storage period and temperature regime, allow you if necessary to quickly change the storage conditions. The analysis made it possible to identify the optimal term and temperature regime of storage of tubers.

Treating Cognitive Symptoms of Generalized Anxiety Disorder Using EMDR Therapy With Bilateral Alternating Tactile Stimulation
Authors: Rodriguez de Behrends Marisa
Published: March 2021

This article reports preliminary evidence for the effectiveness of eye movement desensitization and reprocessing psychotherapy (EMDR) therapy, applying bilateral alternating tactile stimulation in treating cognitive symptoms in patients with generalized anxiety disorder (GAD). A single-case experimental design was used in seven clinical cases. The Penn State Worry Questionnaire, Intolerance of Uncertainty, Cognitive Avoidance Questionnaire, and Negative Problem Orientation Questionnaire were administered at five points during pretreatment (which established the baseline phase serving as each participant's control), at three points during the treatment phase, at the end of it, and at the 3- and 6-month follow-ups. Each participant received 16 treatment sessions. Visual, statistical, and clinical significance analyses were conducted. The cognitive symptoms treated were: excessive worry, intolerance of uncertainty, cognitive avoidance, and negative orientation to problems. All four cognitive symptoms subsided, with large effect sizes in all cases, between pre- and posttreatment, which can be observed in the visual and statistical analysis of each case. Pre- and post-cognitions are specified in each case. According to the clinical significance analysis, all participants evidenced a change towards an improvement. Finally, evidence is given in favor of the usefulness of EMDR therapy for the treatment of cognitive symptoms in participants diagnosed with GAD. However, these results must be considered cautiously when generalizing data.
Factors Associated With Self-Care Among Patients Receiving Hemodialysis: A Cross-Sectional Observational Study
Authors: Lee Juhyun , Noh Dabok
Published: March 2021

Background and Purpose

The global increase in prevalence of individuals with
end-stage renal disease is a rising concern. Self-care is an essential and important component of chronic disease management. Poor self-care in patients receiving hemodialysis is associated with an increased risk of mortality and hospitalization. This study aimed to identify predictive factors for self-care in patients receiving hemodialysis based on a middle-range theory of self-care for chronic illness.

Methods

Adult patients with end-stage renal disease receiving hemodialysis were recruited at an artificial kidney unit in a general hospital. Data from 131 patients were analyzed. Self-report questionnaires assessed hemodialysis-related knowledge, health motivation, self-efficacy, social support, access to care, and self-care.

Results

Participants who had a family caregiver showed significantly higher selfcare scores than those who did not, and self-care scores were higher in patients who reported hypertension as a causal disease of end-stage renal disease than in those who did not. Self-care was significantly correlated with knowledge, health motivation, self-efficacy, social support, and access to care. The study’s regression model showed that self-efficacy, health motivation, and knowledge were predictive variables influencing self-care, and the explanatory power of this model was 55.9%.

Implications for Practice

The results support the middle-range theory of self-care for chronic illness. Strategies and education to improve self-efficacy, health motivation, and knowledge must be incorporated when designing self-care programs. Nursing interventions that patients can participate in with their family members might facilitate improving self-care.

Authors: García-Moyano Loreto , Altisent Rogelio , Delgado-Marroquín María Teresa , Pellicer-García Begoña , Arrazola-Alberdi Oihana , Antón-Solanas Isabel
Published: March 2021

Background and Purpose

Professional commitment is frequently used as a humanistic care indicator. Thus, it is important to design and validate a tool which is able to measure professional commitment of nurses in Spain. In this study we aimed to analyze the psychometric properties of the Nijmegen Professionalism Scale for Spanish (NPS-S) nursing in order to verify its validity and reliability.

Methods

We undertook the pilot testing and psychometric validation of the NPS-S. A total sample of 249 nursing professionals from a variety of areas of expertise took part in this study. The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) Statement was used for reporting this research.

Results

The NPS-S achieved a high degree of content validity, construct validity, internal consistency, temporal stability, and usability; this version is, thus, equivalent to the Nijmegen Professionalis Scale in its original version.

Implications for Practice

Based on the results obtained from the validation of this tool, it is possible to affirm that the NPS-S is an effective instrument for measuring professional commitment in this population. The NPS-S will evaluate and thus contribute to the promotion of professional commitment in Spanish nursing. Additionally, it will serve to establish correlations between professional commitment and other variables including quality of care and patient satisfaction. Future studies should analyze the evaluation capacity of this tool.

Background

The literature on women who use injection drugs (WUIDs) is antiquated and diluted by data from men. Due to the higher rates of morbidity and mortality among WUID, we undertook a qualitative study to better understand their drug use practices.

Methods

We adopted a Deleuze–Guattarian lens and engaged in semi-structured interviews with 35 women in Ottawa, Canada. Data from 31 of these women were analyzed using applied thematic analysis.

Results

We divided these themes into (a) how WUID obtain resources to acquire drug,and (b) the steps involved in preparing, using, and discarding drugs. From our Deleuzo–Guattarian perspective, these findings highlighted that participants stratified their worlds according to rules of cleanliness to create hierarchies of appropriateness and acceptability.

Conclusions

These findings, overall, highlight the importance of understanding the constructed world of WUIDs, particularly regarding the ways in which nurses interact with these women to provide care.
The Size and Growth Potential of the Digital Economy in ODA-eligible Countries
Authors: Herbert George , Loudon Lucas
Published: March 2021

This rapid review synthesises evidence on the current size of the digital market, the countries promoting development of digital business and their approach through Trade Policies or Incentive Frameworks, and the current and potential size of the market with the UK / China / US / other significant countries. It draws on a variety of sources, including reports by international organisations (such as the World Bank and OECD), grey literature produced by think tanks and the private sector, and peer reviewed academic papers. A high proportion of estimates of the size of the digital economy come from research conducted by or for corporations and industry bodies, such as Google and the GSMA (which represents the telecommunications industry). Their research may be influenced by their business interests, the methodologies and data sources they utilise are often opaque, and the information required to critically assess findings is sometimes missing. Given this, the estimates presented in this review are best seen as ballpark figures rather than precise measurements. A limitation of this rapid evidence review stems from the lack of consistent methodologies for estimating the size of the digital economy. The OECD is attempting to develop a standard approach to measuring the digital economy across the national accounts of the G20, but this has not yet been finalised. This makes comparing the results of different studies very challenging. The problem is particularly stark in low income countries, where there are frequently huge gaps in the relevant data.

Contemporary societies exist in the conditions of globalization, which profoundly‎ transforms them in different dimensions. Technological progress enabled‎ the significant changes in the identity dimension. This has, inter alia,‎ resulted in new opportunities for preserving identification with the country of‎ origin, increased interest in the diaspora concept in the politological and sociological‎ thought and caused new approaches and activities by the states in‎ improving relations with their diasporic communities. The former republics‎ of the SFRY, which have been making progress in building legal and institutional‎ capacities for cooperation with diasporas, are no exception. Generally,‎ all of these countries have very numerous and diverse diasporas, which have‎ usually been emerging in a long period of time. This paper analyzes the policies‎ of the states, created by the break-up of the SFRY, towards their diasporas.‎ The policies of these states are specific and they differ from one another,‎ both in defining diaspora and in legal and institutional solutions that should‎ improve diaspora’s link with the country of origin. However, the Republic of‎ Slovenia, the Republic of Croatia, Bosnia and Herzegovina, the Republic of‎ Serbia, Montenegro and the Republic of North Macedonia, have some common‎ elements as well.‎
Moderately Hypofractionated Intensity Modulated Radiotherapy (IMRT) With a Simultaneous Integrated Boost (SIB) for Locally Advanced Head and Cancer – Do Modern Techniques Held Their Promise?

Abstract: Background: Intensity modulated radiotherapy (IMRT) is still a standard of care for radiotherapy in locally advanced head and neck cancer (LA-HNSCC). Simultaneous integrated boost (SIB) and moderate hypofractionation offer an opportunity for individual dose painting and a reduction in overall treatment time. We present retrospective data on toxicity and locore-gional control of a patient cohort with LA-HNSCC treated with an IMRT-SIB concept in compar-ison to normofractionated 3D-conformal radiotherapy (3D-RT) after a long-term follow-up. Methods: Between 2012 and 2014, n=67 patients with HNSCC (stages III/IV without distant me-tastases) were treated with IMRT-SIB either definitively (single/total doses: 2.2/66 Gy, 2.08/62.4 Gy, 1.8/54 Gy in 30 fractions) or in the postoperative setting (2.08/62.4 Gy, 1.92/57.6 Gy, 1.8/54 Gy). These patients' clinical courses were matched (for sex, primary, and treatment concept) as part of a matched-pair analysis with patients treated before mid-2012 with normofractionated 3D-CRT (definitive: 2/50 Gy followed by a sequential boost up to 70 Gy; postoperative: 2/60-64 Gy). Chemotherapy/ immunotherapy was given concomitantly in both groups in the definitive situation (postoperative dependent on risk factors). The primary endpoints were acute and late toxicity; the secondary endpoint was locoregional control (LRC). Results: Sixty-seven patients treated with IMRT-SIB (n = 20 definitive, n = 47 adjuvant) were matched with 67 patients treated with 3D-RT. There were minor imbalances between the groups concerning nonmatching variables such as extracapsular extension (ECE) and chemotherapy in IMRT-SIB. Significantly less toxicity was found in favor of IMRT-SIB concerning dysphagia, ra-diation dermatitis, xerostomia, fibrosis, and lymphedema. After a median follow-up of 63 months, the median LRC was not reached (IMRT-SIB) vs. 69.5 months (3D-RT) (p=0.63). Conclusions: This moderately hypofractionated IMRT-SIB concept was shown to be feasible with less toxicity than conventional 3D-RT in this long-term follow-up observation.
Public Health and Disability—The Importance of Keeping up the Good Work
Authors: Alriksson-Schmidt Ann I. , Hägglund Gunnar
Published: March 2021

Secondary and tertiary prevention strategies targeting people with disabilities to improve their health and wellbeing is important. In Sweden, >95% of all children with cerebral palsy (CP) participate in a follow-up program, where one of the goals is the prevention of hip dislocations. We reviewed the incidence of hip dislocations from 2010 to 2019 and the number of children who underwent different types of hip surgeries. The number of hip dislocations was reduced from 8.8% before introduction of the program to 0.3-0.4% up to 2015, followed by a gradual increase to 0.8% in 2019. The proportion of children who underwent adductor-psoas lengthening as their primary preventive surgery decreased from 50% in 2017 to 37% in 2019 with a corresponding increase of children undergoing femoral osteotomy, indicating more children underwent surgery at a later stage. Reasons for the increased number of children with hip dislocation may be that more children have moved to Sweden in recent years without corresponding compensation in health care resources and increased waiting times for surgery due to, among other things, a shortage of nurses. The results highlight the importance of constantly monitoring follow-up programs.
Facial Emotion Recognition from an Unmanned Flying Social Robot for Home Care of Dependent People

Published: March 2021

This work is part of an ongoing research project to develop an unmanned flying social robot to monitor dependants at home in order to detect the person’s state and bring the necessary assistance. In this sense, this paper focuses on the description of a virtual reality (VR) simulation platform for the monitoring process of an avatar in a virtual home by a rotatory-wing autonomous unmanned aerial vehicle (UAV). This platform is based on a distributed architecture composed of three modules communicated through the Message Queue Telemetry Transport (MQTT) protocol: the UAV Simulator implemented in MATLAB/Simulink, the VR Visualiser developed in Unity, and the new emotion recognition (ER) System developed in Python. Using a face detection algorithm and a convolutional neural network (CNN), the ER System is able to detect the person’s face in the image captured by the UAV’s on-board camera and classify the emotion among seven possible ones (surprise, fear, happiness, sadness, disgust, anger or neutral expression). The experimental results demonstrate the correct integration of this new computer vision module within the VR platform, as well as the good performance of the designed CNN, with around 85% in the F1-score, a mean of the precision and recall of the model. The developed emotion detection system can be used in the future implementation of the assistance UAV that monitors dependent people in a real environment, since the methodology used is valid for images of real people.
