Nadzor nad delom policije v Republiki Italiji
Authors: Koren Fric Jona , Muženić Martin
Published: March 2021

Prispevek prikazuje sistemsko organizacijo državnih policij in mehanizme nadzora nad delom pripadnikov varnostnih sil v Republiki Italiji. Ugotovili smo, da v Italiji na državni ravni delujejo štiri policijske sile (vsaka deluje pod pristojnim resornim ministrstvom), katerih delovanje in nadzor je centraliziran. Neposredni nadzor nad njimi na vseh organizacijskih ravneh izvajajo prefekti, kvestorji, vladni komisarji, generalni poveljniki, pristojno ministrstvo, generalni direktor policije ter Urad javne varnosti in Oddelek javne varnosti v okviru Ministrstva za notranje zadeve. Delovanje policijskih sil v Italiji je zaradi decentraliziranega upravnega sistema precej razdrobljeno, poleg tega pa italijanska ureditev ne pozna organa, ki bi nesporno zagotavljal strokovni, neodvisni in nepristranski nadzor nad policijo. V primeru domnevnih kršitev vlogo tovrstnega organa prevzame sodna policija, ki deluje v okviru Ministrstva za pravosodje ter novoustanovljeni organ Urad za notranje zadeve v okviru Centralnega inšpekcijskega urada, v katerem tako kot tudi v sodni policiji delujejo pripadniki rednih policijskih sil.
Do Instabilities in National Macroeconomic Factors Contribute to Channeling Volatility Spillover from the Global to the Islamic Equity Market?

Published: March 2021

This study investigates the impact of macroeconomic instabilities on returns volatility spillover that is transmitted from the global to the Islamic equity market. The economic factors examined are the exchange rate, inflation rate, interest rate, and production growth. To achieve the purpose of the study, we utilize three analysis tools: a GARCH(p,q) model to derive values of volatility for all variables; an asymmetry dynamic conditional correlation (ADCC) model to produce a measure of volatility spillover as the dependent variable; and a panel data regression technique to assess the causality significance of macroeconomic factors to volatility spillover. This study is the first which expands such approaches. We observe monthly data of world and Islamic market indices, exchange rates, consumer price indices, interest rates, and industrial production indices. The data, which range from May 2002 to February 2019, are taken from the world market, and twenty-three economies, which consist of fourteen developed and nine emerging markets that have Islamic stock indices. In several sections, we provide important additional analysis for five stock markets in Central European economies, which are compared to the others. The finding suggests that the presence of volatility spillover on the Islamic markets that originates from the global market is affected by the internal instabilities of macroeconomic factors, except for industrial production instability for developed markets, including Central European markets. An implication of the study is that regulators should anticipate and prevent adverse consequences of volatility spillover by arranging their internal economic policy to control inflation rates, interest rates, and industrial production growth, as well as exchange rate flexibility. Moreover, market practitioners should include both global market volatility and macroeconomic instabilities in their prediction to create minimum risk.

Актуальность исследования заключается в получении первых изотопно-геохимических данных о природных водах и вмещающих горных породах проявления слаборадоновых вод «Инские источники». Цель: изучить особенности химического состава природных вод и водовмещающих пород и получить первые сведения по суммарной ά- и β-активности природных вод, активности 222Rn и изотопному составу δD, δ18O, δ13С, 234U, 238U, 226Ra и 228Ra. Методы. Отбор проб выполнялся в соответствии с общепринятыми методиками. Лабораторное изучение химического состава методами титриметрии, ионной хроматографии, масс-спектрометрии с индуктивно связанной плазмой проводилось в ПНИЛ гидрогеохимии ИШПР ТПУ. Анализ комплекса изотопных отношений δD, δ18O, δ13СDIC вод и растворенного неорганического углерода проводился в центре коллективного пользования Института геологии и минералогии им. В.С. Соболева СО РАН с помощью прибора Isotope Ratio Mass Spectrometer FinniganTM MAT 253. Данные по суммарной ά- и β-активности природных вод, а также активностях 234U, 238U, 226Ra и 228Ra получены с помощью гамма-спектрометрии и альфа-спектрометрии (после предварительной радиохимической пробоподготовки). Результаты: В 2019 г. в 35 км от г. Новосибирска, вдали от известных гранитных массивов, открыто проявление слаборадоновых вод «Инские источники», относящееся к водам зоны региональной трещиноватости. В настоящей работе приводятся первые результаты их геохимических исследований. Установлено, что воды источников умеренно пресные HCO3 Mg-Ca состава с величиной общей минерализации от 389 до 536 мг/дм3 с содержаниями кремния 4,14–8,61 мг/дм3. Они характеризуются рН от нейтральных до слабощелочных (7,1–8,4), окислительной геохимической обстановкой с Eh +205,3–+231,8 мВ и содержанием О2 раств. 6,24–12,26 мг/дм3. Установленная активность 222Rn варьирует в диапазоне 7–149 Бк/дм3; содержания: 238U от 2,83∙10–3 до 4,13∙10–3 мг/дм3 и 232Th от 2,39∙10–6 до 1,16∙10–5 мг/дм3. По изотопному составу воды имеют инфильтрационное происхождение. Диапазон значений δ18O в водах меняется от –17,1 до –16,7 ‰ со значениями δD от –128,4 до –126,2 ‰ и вариацией δ13C в интервале –13,1 – –10,3 ‰. Вмещающие породы представлены глинистыми сланцами темно-серого (до черного), иногда серого цвета, с небольшой примесью алевритового, песчано-алевритового материала. Изотопный состав кальцита вмещающих пород характеризуется близкими значениями: δ13C варьирует от –3,1 до –2,7‰, δ18O – от 17,2 до 18,4 ‰. Выветрелые глинистые сланцы характеризуются облегчением по δ13C (до –11,0 ‰) и по δ18O (до 13,9 ‰). Также эти образцы по результатам геохимических исследований характеризуется существенным снижением (в несколько раз) содержания всех элементов-примесей (кроме U), свидетельствующим об активном взаимодействии вод с вмещающими породами.

АКЦЕССОРНАЯ ЗОЛОТО-СЕРЕБРЯНАЯ МИНЕРАЛИЗАЦИЯ ИЗ ХРОМИТИТОВ ХАРЧЕРУЗСКОГО УЛЬТРАМАФИТОВОГО МАССИВА (ПОЛЯРНЫЙ УРАЛ)
Authors: Юричев Алексей Николаевич
Published: March 2021

Актуальность исследования обусловлена недостаточной всесторонней изученностью минералогических аспектов ультрамафитовых реститовых массивов, что не дает возможности их обобщения на минералогическом уровне и восстановления полной истории их формирования и преобразования, а также решения целого ряда спорных вопросов петрологии данных объектов. Минералогия акцессорной рудной минерализации из реститовых ультрамафитов является слабо изученным направлением. Цель: изучение акцессорной золото-серебряной минерализации в массивных (средне- и густовкрапленных) хромититах Харчерузского ультрамафитового массива Полярного Урала, реконструкция механизма ее формирования. Методы: изучение рудной минерализации в аншлифах с использованием поляризационного микроскопа AxioScope Carl Zeiss; диагностика химического состава рудной минерализации методом рентгеноспектрального микроанализа с применением электронного сканирующего микроскопа Tescan Mira 3 LMU с энергодисперсионным детектором UltimMax100 (Oxford Instruments). Результаты. Впервые в средне-густовкрапленных хромититах Харчерузского ультрамафитового массива Полярного Урала диагностирована акцессорная золото-серебряная минерализация, представленная трехкомпонентным твердым раствором Au–Cu–Ag, отвечающим по химическому составу медистому золоту (купроауриду), и сульфидом серебра – акантитом (Ag2S). Формирование выявленного акантита, очевидно, было связано с наложенными метаморфическими процессами преобразования исходных ультраосновных пород. Однако вопрос генетической природы Au–Cu–Ag трехкомпонентной природной триады не столь однозначен и требует дополнительного, более глубокого изучения. Не исключается, что выявленное в хромититах медистое золото может относиться к первично мантийному типу, в генезисе которого метаморфические коровые процессы, связанные с заимствованием металлов, находящихся в рассеянном виде в реститовых ультрамафитах или вмещающих породах рамы, не играли какой-либо существенной роли. В пользу этого также свидетельствует близкий состав выявленного купроаурида с медистым золотом из хромититов Войкаро-Сыньинского массива, входящего наряду с Харчерузским массивом в состав Хадатинского офиолитового пояса и, очевидно, имеющего с ним общий глубинный мантийный источник.

GELENEKSELDEN DİJİTALE DEĞİŞEN OYUN KAVRAMI VE ÇOCUKLARDA OLUŞAN DİJİTAL OYUN KÜLTÜRÜ
Authors: BİRİCİK Zeynep , ATİK Abdulkadir
Published: March 2021

Oyun kültürü, geçmişten günümüze bütün topluluklarda, çocuklardan yetişkinlere kadar çeşitli gereksinimlere doyum sağlamak üzere gerçekleştirilmiş bir olgudur. Zaman içerisinde yaşanan sosyal, kültürel, siyasal ve teknolojik gelişmelerle birlikte toplumsal yapı da dönüşmüştür. Özellikle teknolojik gelişmeler, dijital çağı egemen kılmış ve bireylerin dijital yaşamda varlıklarını sürdürmelerini zorunlu hâle getirmiştir. Dijital dönüşüm oyun oynama kültürünü de radikal bir biçimde değiştirmiştir. Geleneksel olarak oynanan çocuk oyunları yerini dijital oyunlara bırakmaya başlamıştır. Yeni dijital kültürün yerlileri olarak çocuklar karşımıza çıkmakta ve bu kültürel yapının en çok etkilenenleri de onlar olmaktadır. Bu bağlamda, değişen oyun kültürü içerisinde çocukların oynamış oldukları serbest oyunlar azalırken, dijital oyunları oynama sıklıklarının sürekli artış gösterdiği görülmektedir. Bu çalışmada Erzurum ilindeki ilköğretim öğrencilerinin dijital oyun oynama eğilimlerinin incelenmesi amaçlanmaktadır. Çalışma tarama modelinde yürütülmüş olup veri toplama aracı olarak demografik bilgileri, dijital oyun oynama eğilimlerini ölçen ve çocuklarda oluşan dijital oyun kültürünü ortaya koymak adına araştırmacı tarafından geliştirilen bir yarı yapılandırılmış mülakat formu kullanılmıştır. Çalışmanın örneklemini Erzurum ili merkezinde yaşayan ve ilköğretime devam eden erkek ve kız çocukları oluşturmaktadır. Sosyoekonomik seviyeleri göz önünde bulundurularak düşük, orta ve yüksek olmak üzere üç okuldan her biri 15 öğrenci olmak üzere toplamda 45 öğrenci ile görüşmeler gerçekleştirilmiştir. Görüşme öncesinde ilgili okullara gidilip, dijital oyun oynayan çocuklar tespit edilerek, kız ve erkek dağılımının eşit olmasına dikkat edilmiştir. Dijital oyun oynayan çocukların hangi dijital oyun oynadıkları, günlük ne kadar süre oynadıkları, çevrimiçi ya da çevrimdışı oyun oynama pratikleri, hangi dijital araçlarla oynadıkları ve çocuklarda dijital oyun kültürünün oluşup oluşmadığı araştırılmıştır. Dijital kültürün hakim olduğu bu çağda çocuklar geleneksel oyun kültüründen daha çok dijital oyun kültürü olarak tanımlanan yeni bir oyun kültürünün oyuncuları olmaktadır. Bu yeni oyun kültüründe çocukların somut oyuncaklarla ve yüz yüze oyun oynamak yerine ekran karşısında sanal ortamlarda oyun oynamaya hızlı ve devamlı bir geçiş yaptıkları görülmektedir.

Epidemiological crisis of 2020: financial situation of the population and social support
Authors: Grishina Elena
Published: March 2021

The paper analyzes the dynamics of the financial situation and social support coverage of various socio-demographic groups in Russia in 2020 during the coronavirus pandemic. The study was based on the data of three population surveys conducted in May, October, and December 2020. The spread of coronavirus had a negative impact on the welfare of the population: almost half of the respondents reported worsening of the financial situation of their families in 2020. Over half of the respondents indicated the need for cash assistance, and almost a quarter of the respondents—the need for food packages. More than a quarter of the respondents who tried to apply for social benefits in 2020 faced with some problems. In early December 2020, more than 40% of the respondents had already received the state social support in connection with COVID-19, mainly as cash payments. However, almost 60% of the respondents, including more than a half of the poor had not received any social assistance related to the pandemic. The respondents rather critically assessed the sufficiency of the state social support: almost 60% of the respondents believed that the state had not taken sufficient steps to support the population. The coronavirus epidemic has shown the importance of the social support efficiency improving through digitalization and better targeting.
Improving the situation of children in divorced families — the way to reduce poverty in Russia
Authors: Rzhanitsyna Lyudmila , Rybalchenko Sergey
Published: March 2021

The level of child poverty in Russia is almost twice the national poverty rate. According to UNICEF's definition, "children living in poverty are those who are deprived of the material, spiritual and emotional resources necessary for survival, development and prosperity, which deprives them of the opportunity to enjoy their rights, to reach their full potential and to participate as full and equal members of society". One of the reasons for child poverty in Russia is the evasion of parents living separately from children from paying child support. The total alimony debt in Russia reached 156 billion rubles in 2020 and continues to grow. According to Rosstat and the Accounts Chamber of the Russian Federation, one in five children under the age of 16, for whom there is arrears on alimony payments appointed by the court, does not receive money. That's almost 1.5 million children. The Family Code of the Russian Federation has established the right of every child to receive maintenance from parents, and children should not experience deprivation due to their parents' irresponsibility, otherwise society and public authorities should be obliged to take special care of children, who do not have sufficient means of subsistence. This algorithm of actions is also contained in paragraph 4 of Article 67.1 of the Constitution of the Russian Federation — the State takes over the responsibilities of parents in relation to children left without care. To achieve the national goal of reducing the level of poverty, fundamentally new approaches to the system of alimony recovery are required, including creation of a State Alimony Fund in Russia, as well as improving the value of the child's quality of life in the eyes of parents and society, strengthening the moral responsibility of parents for children.
Can we use dendrogeomorphology for the spatial and temporal analysis of less intensive mass movement processes?: A case study of three debris flows in NW and W Slovenia
Authors: Konjar Matevž , Levanič Tom , Nagel Thomas Andrew , Kobal Milan
Published: March 2021

Debris flows can transport large amounts of material and therefore present a significant threat to infrastructure and human life. In this research, we used tree-ring width analyses to quantify the response of trees to three debris flow events in NW Slovenia (Javoršček, Srpenica) and W Slovenia (Nikova) for which we know the time of origin. We attempted to date these and similar tree responses in the past and compared the patterns between different tree species. Altogether, we sampled 147 trees across a range of tree species (Fagus sylvatica, Pinus sylvestris, Fraxinus excelsior, Fraxinus ornus, Acer pseudoplatanus, Picea abies, Juglans regia, Acer campestre, Tilia cordata and Ostrya carpinifolia), including reference trees that were outside the debris flow fan. For 91 trees, we constructed tree-ring chronologies and used pointer-year analysis to identify years that had abnormal growth. For the remaining trees (mostly Ostrya carpinifolia, Tilia cordata and Acer pseudoplatanus), we either could not accurately distinguish tree rings or two samples from a single tree showed significantly different growth patterns. The growth patterns of Fagus sylvatica and Picea abies following debris flow events showed a weak response at the Javoršček site and no clear responses at the other two sites. Tree species responded similarly at the same locations. Due to the lack of a clear response pattern, we were not able to reconstruct past debris flows.
A VIOLÊNCIA DA PALAVRA: UMA ANÁLISE BAKHTINIANA DO ENUNCIADO “CALA A BOCA”
Authors: SILVA RICARDO DA , SANTOS WILTON PETRUS DOS , SILVA VANESSA MARIA COSTA BEZERRA
Published: March 2021

Este artigo objetivou analisar a radicalização e assunção dos sentidos materializados por discursos que traduzem o desejo de fazer calar, isto é, que reverberam a opressão. Considerando o sentido amplo do conceito de diálogo em Bakhtin, através de uma pesquisa exploratória, qualitativa e bibliográfica, correlacionamos enunciados produzidos em momentos distintos no Brasil pelo General Newton Cruz em 1983 e por Jair Bolsonaro em 2016 e 2020. Das conclusões possíveis, ressalta-se que a política opressora busca vetar a autonomia e a liberdade de expressão através da discursividade una e idêntica, reprimindo a palavra do outro; logo, manifesta-se um movimento de constituição da autoconsciência e da autoimagem que não escuta e desconsidera outros pontos de vista.

Published: March 2021

Uma notícia traz enunciados e imagens que se imbricam na contradição constitutiva de sujeitos e sentidos. A notícia de um evento lúdico realizado na fronteira que separa o México dos EUA possibilita entradas de leitura para pensar os processos migratórios, na relação entre as fronteiras simbólicas constituídas na e pela linguagem. Este artigo traz análises de recortes desta notícia, focalizando diferentes modos de formulação que movimentam sentidos numa atualização da memória a partir de determinadas posições discursivas. Da mesma forma que as gangorras sobem e descem, nesse movimento simbólico de continuidade e ruptura, os dizeres sobre os migrantes e os refugiados ressoam afetados por uma construção imaginária sobre aqueles que ocupam esses lugares.
Consumo de Álcool nos Estudantes do Ensino Superior de Coimbra e o Impacto das Festas Académicas
Authors: Coimbra Trigo André , Santiago Luiz Miguel
Published: March 2021

Introdução: Na literatura internacional, nacional e em estudos no ensino superior em Portugal os jovens apresentam consumos alcoólicos excessivos e binge drinking. Contudo, não se encontra estabelecida qualquer relação entre o consumo e as festas académicas. O objectivo deste estudo foi compreender a associação entre consumo de bebidas alcoólicas e festas académicas, estabelecendo uma relação entre estes momentos e um padrão específico de consumo, bem como perceber a ocorrência de padrões específicos de consumo de acordo com o sexo e os anos de frequência escolar.Material e Métodos: Foi elaborado um questionário, constituído pelo “Alcohol Use Disorders Identification Test – Consumption” (AUDIT-C) e apresentando a questão “Qual a bebida mais consumida?” num mês com festas académicas e num mês sem que se realizassem. O questionário dirigido a alunos da Universidade de Coimbra e do Instituto Politécnico de Coimbra, foi divulgado na página de Facebook® da Universidade de Coimbra.Resultados: Na amostra de estudantes do ensino superior de Coimbra, com idade igual ou superior a dezassete anos (n = 503), o AUDIT-C em mês com festas académicas é superior ao mês sem festas, verificando-se correlação positiva forte e significativa (ρ = 0,711; ρ < 0,001). Em mês sem festas académicas, 41,8% do sexo feminino e 24,0% do sexo masculino apresentam AUDIT-C positivo. Em mês com festas académicas 73,8% do sexo feminino e 56,3% do sexo masculino apresentam AUDIT-C positivo. O sexo feminino apresenta maior risco de consumo excessivo (ρ < 0,001) e bebe mais bebidas espirituosas / shots. Há diferença significativa entre sexos quanto à bebida mais consumida (ρ < 0,001).Discussão: O consumo de alcool é superior nos primeiros anos, embora as festas académicas pareçam ter um impacto proporcional independente do número de matrículas. Em mês com festas académicas, há maior frequência de binge drinking e de consumo superior ao máximo diário recomendado. O sexo masculino revela aumento do consumo de bebidas espirituosas / shots.Conclusão: As festas académicas fomentam as ocasiões de binge drinking pré-existentes, residindo o problema na forma como os jovens abordam o consumo de álcool.
A ESTRUTURA DIALÉTICA DA POLÍTICA EM HENRIQUE CLÁUDIO DE LIMA VAZ
Authors: Silva Manuel Moreira da
Published: March 2021

Este trabalho explicita a estrutura conceptual da Política em Henrique Cláudio de Lima Vaz. Essa estrutura não fora explicitada nela mesma pelo próprio Lima Vaz, que, não obstante, de modo preciso, estabelecera suas linhas gerais no escrito “Ética e Direito”, capítulo quarto dos Escritos de Filosofia II. Ética e Cultura, de 1988, mas escrito originalmente ainda em 1977, texto sobre o qual o trabalho se debruça, para efeito da explicitação da concepção vaziana da Política. O trabalho explicita inicialmente as linhas gerais do desenvolvimento dialético em Lima Vaz e sua concepção de que o método deve adaptar-se ao conteúdo. Em seguida, discute a ideia vaziana de sistema da filosofia e sua organização dialética; quando se passa então à tematização da estrutura silogística da Política, entendida como continuidade da Ética, no sentido de Aristóteles, e, portanto, como Ciência filosófica do Direito, no sentido de Hegel. Enfim, o trabalho busca mostrar a adequação de tal estrutura às estruturas da Ética e da Antropologia.
PADRE VAZ E A COMPREENSÃO DO SEU TEMPO

Este artigo pretende evidenciar a singular compreensão filosófica do Padre Vaz de alguns problemas de fronteira entre filosofia e teologia, sobre as relações entre cristianismo e sociedade e cristianismo e utopia, expressa em três Editoriais da revista Síntese nos anos 1980. A compreensão do Padre Vaz dessas questões que marcaram profundamente a discussão acadêmica, filosófica e teológica brasileira, daqueles anos, coincide substancialmente com a compreensão filosófica dessas mesmas questões no ambiente cultural europeu, expressa em dois artigos de Eric Weil, publicados entre 1953 e 1962.

Published: March 2021

A total of 744 samples of vegetable seeds and oil (soybean, sunflower, canola, olive, corn, and mustard) were collected for the presence of aflatoxin B1 (AFB1) and total aflatoxins (AFs). The results have shown that 92 (56.7%) samples of branded and 108 (57%) samples of non-branded edible seeds were observed to be contaminated with AFs. The maximum mean of AFB1 and total AFs in non-branded soybean seeds was 21.01 ± 4.70 and 36.37 ± 6.10 µg/kg, respectively. Furthermore, all samples of edible seeds have concentrations of AFB1 greater than the proposed limit of European Union (EU, 2 µg/kg) and 12 (7.40%) samples of branded seeds and 14 (7.40%) samples of non-branded seeds were found in the range ≥ 50 µg/kg. About 78 (43.3%) samples of branded edible oil and 103 (48.3%) sample of non-branded edible oil were observed to be positive with AFs, and the elevated average of AFB1 (14.29 ± 2.51 µg/kg) and total AFs (25.61 ± 7.50) µg/kg were found in non-branded soybean oil samples. Furthermore, 16 (8.88%) and 6 (3.33%) samples of branded vegetable oil have levels of total AFs in a range (21 - 50 µg/kg) and ≥ 50 µg/kg, respectively. The findings have indicated significant difference of AFs levels between branded and non-branded vegetable oil samples (t = 22.274 and p = 0.000) at α = 0.05 and significant difference of AFs levels in vegetable seeds and oil samples ( t = -17.75, p = 0.000) at α =0.05. The highest dietary intake was found in non-branded sunflower oil sample (0.90 µg/kg/day) in female individuals (16-22 age group), followed by the dietary intake of 0.69 µg/kg/day body weight in male individuals (16-22 age group).

Authors: Lu Chenxi , Wen Conghua , Bie Jing , Zhou Shijian
Published: March 2021

We report the experiences of the bike sharing system in Ningbo, China. To analyze the impact of the system, system log data are collected for the whole month of May 2014 (with more than 1.7 million usage records), supplemented by questionnaire data from 1,856 respondents. Our results show that public bike usage follows the same pattern as road traffic, with morning and evening peaks on week days. In terms of mode substitution, 16% of public bike trips would have been made by private cars. In average, each public bike is used 3.7 times per day, with each trip lasting around 23 minutes and covering around 3.5 kilometre. This translates into a reduction of car travel by more than 11 million kilometre per year, a significant contribution to the sustainability of urban transport in Ningbo.

The paper examines the specific case of massive intervention by governments and, especially, central banks in monetary and financial markets to deal with the pandemic by seeking to lessen its effects. Also, it is offered a critical analysis on simultaneous government policies involving taxes and an increase in public spending which are presented as the panacea and universal remedy for the evils that afflict the society, instead of promoting the transit to Wellbeing Economics. To conclude the review, there is a proposal of paradigm review, in the way to offer a sustainable model.

The objectives of the current research were to determine the levels of deoxynivalenol (DON) in four different cultivars of corn and subsequently to investigate the fate of DON during pro-cessing steps involved for the production of cornbread. The samples (n = 30) of each cultivar which were found positive were selected for the study. The average level of DON was ranged from LOD to 650 µg/kg. The amount of DON in cornflour samples were ranged from LOD to 630 µg/kg and insignificantly lower than the levels found in corn grain samples (p ≥ 0.05). Further-more, the levels of DON in corn dough samples were insignificantly higher than the levels in cornflour samples (p ≥ 0.05), with levels ranged from LOD to 645 µg/kg. However, the amount of DON in cornbread samples was significantly different from the levels found in corn grains sam-ples (p ≤ 0.05), with levels ranged from LOD to 611.5 µg/kg. The percentage reduction of DON in grains to cornbread samples was 22.4%, 35.6%, 44.5%, and 42.6% in type 1, type 2, type 3, and type 4 cultivars, respectively. The highest dietary exposure and hazard quotient (HQ) of DON was 0.13 and 0.17 µg/kg bw/d, in male and female individuals resulted from the consumption of cornbread samples, respectively.

Human populations and natural ecosystems are bound to be exposed to ionizing radiation1from the deposition of artificial radionuclides resulting from nuclear accidents, nuclear devices2or radiological dispersive devices ("dirty bombs"). On the other hand, NORM industries such as3phosphate production or uranium mining, contribute to the on site storage of residuals with enhanced4concentrations of natural radionuclides. Therefore, in the context of the European agreements5concerning nuclear energy, namely the EURATOM (European Atomic Energy Community) Treaty,6monitoring is an essential feature of the environmental radiological surveillance. In this work, we7obtain 3D maps from outdoor scenarios, and complete such maps with measured radiation levels8and with its radionuclide signature. In such scenarios, we face challenges such as unknown and9rough terrain, limited number of sampled locations and the need for different sensors and therefore10different tasks. We propose a radiological solution for scouting, monitoring and inspecting an area of11interest, using a fleet of drones and a controlling ground station. First, we scout an area with a LiDAR12onboard a drone to accurately 3D-map the area. Then, we monitor that area with a Geiger-Muller13sensor at a low-vertical distance from the ground to produce a radiological (heat)map that is overlaid14on the 3D map of the scenario. Next, we identify the hotspots of radiation, and inspect them in detail15using a drone by landing on them, to reveal its radionuclide signature using a CZT sensor. We present16the algorithms used to implement such tasks both at the ground station and on the drones. The three17mission phases were validated using actual experiments in three different outdoor scenarios. We18conclude that drones can not only perform the mission efficiently, but in general they are faster and19as reliable as personnel on the ground

Background. The characterization of new biomarkers of COVID-19 is extremely important. Few studies measured the soluble receptor for advanced glycation end product (sRAGE), angiotensin-converting enzyme 2 (ACE2), calcium and magnesium in COVID-19. Aims: To measure sRAGE, ACE2, interleukin (IL)-6, IL-10, CRP, calcium, magnesium, and albumin in COVID-19 patients in association with peripheral oxygen saturation (SpO2) and chest CT scan abnormalities (CCTA) including ground glass opacities. Methods. This study measured sRAGE, ACE2, IL-6, IL-10, CRP using ELISA techniques, and calcium, magnesium, and albumin using a spectrophotometric method in 60 COVID-19 patients and 30 healthy controls.Results. COVID-19 is characterized by significantly increased IL-6, CRP, IL-10, sRAGE, ACE2, and lowered levels of SpO2, albumin, magnesium and calcium. Neural networks showed that a combination of calcium, IL-6, CRP, and sRAGE yielded an accuracy of 100% in detecting COVID-19 patients with calcium being the most important predictor followed by IL-6, and CRP. COVID-19 patients with CCTAs showed lower SpO2 and albumin levels than those without CCTAs. SpO2 was significantly and inversely correlated with IL-6, IL-10, CRP, sRAGE, and ACE2, and positively with albumin, magnesium and calcium. Patients with positive IgG results showed a significant elevation in the serum level of IL-6, sRAGE, and ACE2 compared to the negatively IgG patient subgroup.Conclusion. The results show that immune-inflammatory and RAGE pathway biomarkers may be used as external validating criterion for the diagnosis COVID-19. Those pathways coupled with lowered SpO2, calcium and magnesium are drug targets that may help to reduce the consequences of COVID-19.
Electrochemical Biosensors in Food Safety: Challenges and Perspectives
Authors: Curulli Antonella
Published: March 2021

Safety and quality are key issues for the food industry. Consequently, there is a growing demand to preserve the food chain and products against substances toxic, harmful to human health such as contaminants, allergens, toxins, or pathogens. For this reason, it is mandatory to develop highly sensitive, reliable, rapid, and cost-effective sensing systems/devices such as electrochemical sensors/biosensors. Generally, conventional techniques are limited by long time of analyses, expensive and complex procedures, and they require skilled personnel. Therefore, the development of performant electrochemical biosensors can significantly support the screening of food chain and products. Here, we report some of the recent developments in this area and analyze the contributions produced by electrochemical biosensors in the food screening and the challenges to address.

Most smallscale farmers still use the traditional way of agricultural crop farming, and relay mostly use of chemical fertilizers (CF). Recently CF have become expensive and could in some way have a negative impact on soil quality after long term application. However, co-application of biogas slurry (BGS) with CF could help reduce farming costs while improving dry matter yields, grain yields, primary macronutrient uptake of (Nitrogen) N, (Phosphorus) P, (Potasium) K, (Calcium) Ca and (Magnesium) Mg and soil concentration of pH, (organic carbon) OC, N, P, K, Ca and Mg after crop harvest. The study was a field experiment conducted in 2016-2017 and 2017-2018 growing seasons. The field experiment was arranged in a randomized complete block design with four replicates. The treatments were based on percentages of recommended N rates of 120 kg N ha-1 for maize production. The BGS/CF treatments were (i) 0/0, (ii) 0/120, (iii) 24/96, (iv) 48/72, (v) 72/48, (vi) 96/24, (vii) 120/0 kg N ha-1. The spreading of the combination of BGS/CF treatments was performed by hand and incorporated into the top soil (0-10 cm) in each experimental plots. BGS/CF (48/72) treatment resulted into higher dry matter yield in 2016-2017, which was higher than all other treatment combinations, while in the 2017-2018 season, treatment of (0/120) resulted into higher dry matter than all other treatment combinations. The 48/72 and 0/120 treatments resulted into similar grain yield in 2016-2017 season which were higher than all other treatments. Treatments of 48/72, 72/48 and 120/0 had higher N, P, K, Ca and Mg uptake than 0/0, 0/120, 24/96 and 96/24 treatments in both seasons. Soil pH, total N, K, and Mg were high from the treatment of (120/0) than all other treatments in 2016-2017 while in the 2017-2018 season, treatment of (48/72) had higher OC, P and K after maize harvest. The findings of his study show that co-application of BGS/CF at 48/72 and 72/48 have maize yield benefits compared to the two resources, BGS/CF (120/0) and BGS/CF (0/120), applied separately in soil especially in the arid and semi-arid regions.

Published: March 2021

Evidence supports an association between low magnesium (Mg) intake and coronary heart disease and between Mg intake and endothelial function. The aim of this study was to assess the effect of one week of Mg supplementation on endothelial function, assessed by flow mediated dilatation (FMD). Nineteen healthy men and women completed this cross-over pilot study in which participants were randomised to take an over-the-counter magnesium supplement for one week or to follow their usual diet. Weight, FMD and blood pressure (BP) were taken on completion of each intervention and 24hour urine collections and blood samples were taken to assess compliance. Baseline serum Mg was within normal range for all participants. Urinary Mg and urinary magnesium-creatinine ratio (Mg/Cr) significantly increased between interventions, (p = 0.03, p = 0.005 respectively). No significant differences in FMD or BP were found between the interventions. A significant negative correlation was seen between age and FMD (r = -0.496, p = 0.031). When adjusted for age, saturated fat was negatively associated with FMD (p = 0.045). One week of Mg supplementation did not improve FMD in a healthy population.

Published: March 2021

Composite is a material that consisting of two or more materials, either micro or macro, where the properties of the material differ in shape and chemical composition from the original substance. In this study, fatigue testing of fiber metal composites was carried out to determine the rate of crack propagation so that the age of the fiber metal composite specimen was known. The independent variable in this research is the angular orientation of the carbon fiber and the surface roughness of the aluminum with the dependent variable response is the bridge crack rate. The manufacture of fiber metal laminates specimens uses the Vacuum Resin Infuse (VARI) method, which uses a vacuum pump as a means to flow the resin from the reservoir to the mold. This method is used to minimize the occurrence of air bubbles trapped on the specimen which causes porosity defects which will reduce the strength of the metal laminates specimen itself. Fatigue testing is performed using the stress amplitude method. That is, the value of the load when the tensile test is one third of the tensile strength. After the fatigue test was carried out, the results were obtained on specimens with an angular orientation of 0/90 ° fibers, the crack propagation rate slowed down with a cycle value of 90000 in specimens with a surface roughness value of 2.128 µm then decreased cycles on specimens with a value of 2.887 µm, namely 11000 cycles.
