Model Pendampingan Melalui Kelompok Perpuluhan Dalam Meningkatkan Kemampuan Pengelolaan Diabetus Melitus di Rumah Pada Penyandang Diabetes Mellitus Type II
Authors: Ekwantini Rosa Delima
Published: March 2018

According to the Center for Data and Information PERSI (2003,) the prevalence of diabetes mellitus type II increased. WHOestimates that the global prevalence of type II diabetes will increase from 171 million in 2000 to 366 million in 2030, andIndonesia ranked fourth after the United States, China and India. Riskesdas (2013) showed that the prevalence of DM inYogyakarta in 2013 was 2.6% and the diagnosis based on the diagnosis and symptoms of 3.0%. Results of a preliminarystudy conducted by researchers obtained data on the number raised DM 2014 in Puskesmas I Gamping Sleman many as270 people. DM disease if left untreated can lead to complications or fatal complications such as coronary heart disease,kidney failure, blindness, infections due to ulcer until amputated the affected part ulcers and can lead to death. Dasawismaperpuluhan group is a group whose members consist of people or families with the same health problems who live nearby.This group is one way for fostering community participation in the health sector so that the public be aware of the healthproblems experienced thus participate in solving the problem. The purpose of this study to determine the effect throughperpuluhan group mentoring model to DM management improvement at home in persons with diabetes mellitus type II. Typeof this research is quasi experimental design with pretest-posttest design with control group. The number of samples in thisstudy were 64 respondents that were divided into 32 groups of respondents with assistance through the perpuluhan group(treatment group) and 32 respondents with assistance through Elderly Posyandu (the comparison group). Sampling usedconsecutive sampling. Data were analyzed using Mc Nemar test and Chi square. Respondents who received assistancethrough the perpuluhan group capable of managing diabetes at home as much as 25 respondents (39.06%), while thosegetting assistance through Elderly Posyandu were 14 respondents (21.89%). Respondents who received assistancethrough perpuluhan groups that are unable to manage diabetes at home as much as 7 respondents (10.94%), while thosegetting assistance through Posyandu Elderly many as 18 respondents (28.11%) p = 0.005 <0.05. It can be concluded thatmentoring activities through a perpuluhan group is more effective than assistance through Posyandu Elderly in improving theability of the management of DM at home in the DM type II patient.

Religious Doctrines Versus Economics in the Antiquity and the Middle Ages
Authors: Wójcicki Włodzimierz
Published: March 2018

Summary Subject and purpose of work: The work presents the participation of religious ideas in shaping ethical attitudes in business. Its purpose is to indicate the need to consolidate ethical principles in economics with the use of various possibilities of social persuasion. Materials and methods: The research was based on literature studies, including religious, philosophical and historical literature. In particular, the method of induction was employed - from rules to conclusions. Attention was paid to the considerations of the method itself. Results: The development of research on the method required the recognition of the role of reason - autonomous with respect to faith. Findings of St. Thomas Aquinas (distinction between act and possibility, forms and matter, recognition of the causal linkage between events, negation of the dual truth about the same event) and W. Ockham (entities are not to be multiplied without necessity) are still valid today. Conclusions: Religious ideas support economic activity by propagating ethical norms of behaviour. This, in turn, evokes the view of J.M. Keynes about the important role of ideas as such. The significance of the Bible goes far beyond religious aspects.
Ecological Activity as Part of the Corporate Social Responsibility Concept Area (Based on the Example of Agricultural Enterprises in Rural Areas)
Authors: Ratajczak Marcin , Wołoszyn Jan
Published: March 2018

Subject and purpose of work: The purpose of this article is to show the results of the analysis of the involvement of micro-, small and medium-sized agribusiness enterprises operating in rural areas with reference to the issues of social responsibility in protection of natural environment. Materials and methods: Research on entrepreneurs’ views on CSR activities was conducted at the turn of 2016 and 2017 and included 212 micro (0-9 persons), small (10-49 employees) and medium (50-249 employees) agribusiness enterprises conducting business activity in the rural areas of the Wielkopolska province. Results: The conducted research has confirmed the common view that micro enterprises show little interest in implementing basic standards of social responsibility in the “environment” area. The situation is slightly better for small and medium enterprises. Conclusions: Pro-environmental activities, especially in the agribusiness sector, should be promoted, highlighting the range of benefits that can be achieved through these activities, such as improving relationships with the local community, increasing employees’ motivation, and increasing customers’ loyalty.
El normalismo rural mexicano y la "conjura comunista" de los años sesenta. La experiencia estudiantil de Cañada Honda, Aguascalientes
Authors: Ortiz Briano Sergio , Camacho Sandoval Salvador
Published: March 2018

La historia del normalismo rural mexicano suele asociarse a una historia de lucha y protesta en contra del gobierno; pero el movimiento estudiantil no ha sido homogéneo. Una de las mayores escisiones que ha tenido el normalismo rural mexicano ocurrió en 1959, no obstante, cinco años después, en la Escuela Normal Rural "Justo Sierra Méndez", de Cañada Honda, Aguascalientes, estudiantes normalistas se reunieron en el Congreso de la Unidad del Normalismo Rural para fortalecer su presencia polí­tica y social en todo el paí­s y lograr que se les atendieran sus demandas particulares. El propósito de este artí­culo es analizar la dinámica que se generó entre estudiantes normalistas y autoridades durante los primeros años de la década de los sesenta, identificando, por un lado, las estrategias usadas por el estudiantado que buscaba hacerse visible y que sus demandas fueran atendidas y, por otro lado, las medidas que tomaron las autoridades gubernamentales para atemperar el protagonismo estudiantil. Esta confrontación era parte de las movilizaciones obreras y magisteriales en contra de un gobierno que usaba la fuerza y el discurso anticomunista para anular toda expresión de inconformidad y oposición ciudadana.

O experimento foi conduzido em casa de vegetação na área experimental do IF Goiano Câmpus Ceres. O delineamento foi inteiramente casualizado em esquema fatorial 2x4 com duas fontes de N (ureia normal e protegida), quatro doses N (0, 80, 160, 240 mg dm-3) e oito repetições. Cada unidade experimental foi constituída por tubetes com capacidade para 0,3 dm3 de solo e duas plantas. Foram realizadas duas aplicações de cobertura sendo a primeiro no dia seguinte ao desbaste e a segunda dez dias após a primeira. As fontes de nitrogênio aumentaram a altura das plantas, com resposta linear. Para o número de folhas a maior quantidade foram obtidas com dose de 177,77 e de 350 mg dm-3, para ureia protegida e normal, respectivamente. A massa fresca de raiz a dose que possibilitou maior quantidade foi de 150 mg dm-3 para ureia protegida e de 350 mg dm-3 para ureia normal. A massa fresca da parte aérea as doses de 200 e 350 mg dm-3 para ureia protegida e normal, respectivamente, proporcionaram maior massa. A massa seca das folhas apresentaram maiores valores na dosagem de 176,5 mg dm-3 de ureia protegida e de 192,3 mg dm-3 de ureia normal. O número de folhas, massa fresca de raízes e parte aérea e massa seca das folhas apresentaram respostas quadráticas. A adubação nitrogenada promove incrementos nas características agronômicas de rúcula.

Objetivou-se com este estudo avaliar o efeito da hidrólise alcalina sobre o comportamento da temperatura e as reduções dos sólidos e da fração fibrosa no processo de compostagem da cama obtida durante a terminação de ovinos. O experimento foi conduzido em delineamento inteiramente casualizado com três tratamentos e cinco repetições (leiras) e com os seguintes tratamentos experimentais: 1 - apenas cama da criação de ovinos; 2 -  cama da criação de ovinos acrescida de 0,8% dos sólidos totais (ST) de cal hidratada; tratamento 3: cama da criação de ovinos acrescida de 1,6% dos ST de cal hidratada. A eficiência do processo de compostagem foi avaliada pelas reduções de ST, sólidos voláteis (SV), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA) e hemicelulose, além da temperatura. Foram observadas diferenças (P<0,05) entre os tratamentos para as características mensuradas durante o processo de compostagem, com exceção da temperatura e o FDA que não diferiram entre os tratamentos testados. Foram observadas reduções (P<0,05) de 28,10 e 35,32% de ST e 34,32 e 42,48 % de SV para as doses 0 e 1,6% de cal hidratada, respectivamente. As maiores reduções (P<0,05) observadas foram de hemicelulose, sendo encontrados valores de 29,07 e 44,14% para as doses de 0 e 1,6% de cal hidratada, respectivamente. Concluiu-se que a hidrólise alcalina com 1,6% de cal hidratada foi eficiente no tratamento da cama de ovinos, permitindo um aumento significativo nas reduções de sólidos totais, sólidos voláteis e fibra durante o processo de compostagem.
Desafios para utilização eficiente da fitase na nutrição de peixes
Authors: Costenaro-Ferreira Cristiano , Della Flora Marco Aurélio Lopes
Published: March 2018

O ácido fítico (IP6) é o principal estoque de fósforo nas plantas e representa entre 50 e 80% do fósforo total presente nos ingredientes vegetais. Por ser indigestível pelos animais não ruminantes e permanecer carregado negativamente no pH fisiológico, liga-se a uma grande variedade de nutrientes, principalmente cátions, os quais são eliminados via fezes. Este fato torna necessária a suplementação de fósforo disponível o que aumenta os custos e problemas ambientais. Em vista disso, a fitase tem sido utilizada como forma de degradar a molécula de IP6 e aumentar o aproveitamento do fósforo indisponível. Esta enzima é usada com sucesso na alimentação de aves e suínos, porém controversa para peixes. Como toda enzima, a fitase possui uma faixa de temperatura e pH ótimos para atuar e desnatura quando submetida a extremos. Assim, o processamento da ração (extrusão) e as diversas condições anatômicas e fisiológicas das espécies de peixe desafiam sua integridade e atuação. Em vista disso, entender os principais aspectos envolvidos nos resultados obtidos com o uso da fitase na alimentação de peixes, conduz ao seu uso correto considerando as condições para sua atividade e os desafios impostos tanto pelo processamento quanto pela espécie de peixe.

O girassol (Helianthus annuus L.) é uma espécie vegetal que apresenta inúmeras aplicações na atualidade, sendo considerada uma das plantas que apresenta um potencial máximo de sua produção. Objetivou-se com este trabalho avaliar aspectos fotossintéticos de cultivares de girassol, submetidas a diferentes regimes hídricos. O trabalho foi realizado em casa de vegetação, nas instalações pertencentes ao Departamento de Engenharia Agrícola da UFCG, conduzido em delineamento inteiramente casualizado em esquema fatorial 3 x 4 (três cultivares e quatro níveis de irrigação) com quatro repetições. Foram utilizados vasos com capacidade para 100 L, tendo-se o conteúdo de água do solo  monitorado diariamente por meio de uma sonda de capacitância, modelo DIVINER 2000®, segmentada nos tratamentos com 100% da capacidade de campo (CC). Foram avaliadas as características: fluorescência da clorofila a, teores de clorofila a, b e total, e índice relativo SPAD. Houve diferença estatística entre as cultivares para o índice relativo de clorofila e o teor de carotenoides, e entre os regimes hídricos para os teores de clorofila b e clorofila total. Houve correlação entre o índice de clorofila (SPAD) e o teor de clorofila total. Os regimes hídricos não alteraram a fluorescência e o teor da clorofila a, entretanto, alteraram os teores de clorofila b e total em plantas de girassol.

O aumento da vida de prateleira é fundamental para ampliar a comercialização dos frutos de tangerina e assim alçar mercados mais distantes. Nessa linha, o presente trabalho teve por objetivo avaliar o melhor tempo de exposição à radiação ultravioleta UV-C na longevidade pós-colheita desse fruto. Avaliou-se os tempos de exposição por cinco, dez, quinze e vinte minutos além de frutos que não foram expostos configurando a testemunha, os frutos foram armazenados sob refrigeração a temperatura de 15°C e avaliados por 25 dias. A cada cinco dias avaliou-se a perda de massa fresca, firmeza, sólidos solúveis, acidez titulável, pH, ácido ascórbico, relação SS/AT e taxa respiratória. Com exceção do pH, os demais resultados mostraram variação estatística em todas as características avaliadas. Os tempos de exposição por quinze e vinte minutos apresentaram resultados semelhantes em todos os tempos de armazenamento e revelaram melhores médias quanto à qualidade pós-colheita dos frutos. Independente do tempo de exposição, à radiação UV-C mostrou-se como uma técnica promissora para a conservação das tangerinas ampliando sua vida útil mesmo quando mantidas sob refrigeração.

O emprego da enxertia pode induzir maior vigor nas plantas, maior produtividade e resistência a patógenos de solo. No entanto, para aplicação de seus benefícios é necessário o estabelecimento do estádio ideal para sua realização e da combinação porta-enxerto e enxerto mais adequada, ou seja, conhecer a relação de compatibilidade e incompatibilidade entre os mesmos. Diante do exposto o objetivo deste trabalho a utilização de diferentes genótipos de cucurbitáceas como porta-enxertos para o meloeiro rendilhado ‘Fantasy’ e seus efeitos sobre a produção do meloeiro. Para tanto, empregou-se o delineamento em blocos casualizados com 33 tratamentos, constituídos pelos diferentes genótipos de cucurbitáceas utilizados como porta-enxertos, auto-enxertia e testemunha sem enxertia e quatro repetições para estudo de compatibilidade. Empregou-se a técnica de enxertia por fenda-cheia e as plantas foram cultivadas em casa de vegetação, avaliou-se características como, porcentagem de sobrevivência das plantas, diâmetro do caule, abaixo, na região e acima da região de enxertia, além de variáveis qualitativas, como, teor de sólidos solúveis, e rendilhamento e quantitativas, como massa média dos frutos e espessura de polpa. O porta-enxerto pepino ‘Caipira’ proporcionou os maiores valores de produtividade.

Published: March 2018

A rúcula é uma das hortaliças que vem ganhando grande importância econômica e, estudos com nitrogênio para aumento da rentabilidade é necessário. O objetivo deste trabalho foi verificar a influência de doses de nitrogênio aplicados via fertirrigação na cultura da rúcula em Latossolo Vermelho distroférrico. O trabalho foi realizado na Universidade Federal da Grande Dourados, em Dourados, MS, cujo solo é descrito como Latossolo Vermelho distroférrico. Utilizou-se o delineamento experimental em blocos casualizado com quatro blocos. Os tratamentos foram compostos por seis doses de nitrogênio aplicadas na água de irrigação (zero, 40, 80, 120, 160 e 200 kg de N ha-1). A semeadura foi realizada no dia 20 de novembro de 2013 e, a emergência ocorreu 3 dias após a semeadura. A colheita foi realizada aos 25 dias após a emergência, sendo que os parâmetros avaliados foram o comprimento da parte aérea, número de folhas, diâmetro do caule, massa seca da parte aérea e produtividade. Foi realizado a análise de variância e, quando os parâmetros foram significativos, procedeu-se a análise de regressão. Conclui-se que os parâmetros da rúcula, comprimento da parte aérea, diâmetro do caule, massa seca e produtividade são influenciados pelas doses de nitrogênio em cobertura aplicadas via fertirrigação. Em função das doses de nitrogênio a produtividade ajustou ao modelo de regressão linear crescente até a dose máxima de nitrogênio de 200 kg ha-1.

O objetivo do presente trabalho foi avaliar a produção de forragem de três espécies de gramíneas forrageiras tropicais submetidas a diferentes níveis de sombreamento. O experimento foi realizado em casa de vegetação no setor de Fitotecnia da Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Aquidauana (UEMS/UUA), sendo o solo da área classificado como Argissolo Vermelho Amarelo distrófico. Os tratamentos foram compostos pela combinação de três espécies de gramíneas (B. brizantha cv. Marandu, B. decumbens cv. Basilisck e Panicum maximum cv. Tanzânia), submetidas a quatro níveis de sombreamentos (0, 30, 50 e 75%), sendo dispostos em um delineamento experimental inteiramente casualizado, em esquema fatorial 3 x 4, com oito repetições. Após a colheita, as plantas foram separadas em parte aérea e raízes, para determinação da produção de massa verde fresca da parte aérea (SFM), massa seca da parte aérea (SDM) e massa seca da das raízes (RDM). Após a análise de variância, o fator qualitativo foi submetido à comparação de médias pelo teste Tukey e o quantitativo à análise de regressão polinomial, sendo as interações desdobradas adequadamente. Verificou-se que B. decumbens, por sua produção de forragem linearmente crescente e menor decréscimo de formação de raízes, é a espécie mais recomendada para condições de sombreamento em relação aos capins Marandu e Tanzânia.
Biografias silenciadas: um percurso semiótico do herói em Lima Barreto e Theodoro Sampaio
Authors: Batalha Cassia Vanessa , Scherer Daniela Raffo , Salermo Renan Luis
Published: March 2018

Na tentativa de trazer à tona uma discussão acerca da contribuição dos negros na construção da identidade nacional brasileira, este trabalho analisa o percurso semiótico de duas personalidades: Lima Barreto e Theodoro Sampaio. O primeiro destacou-se na área da literatura e o segundo, na geografia. A trajetória do homem negro no Brasil foi marcada pela luta de forças, traduzida no desequilíbrio entre os sujeitos, marcada pelo discurso da intolerância e pela reprodução de preconceitos – presentes na educação escolar e cujo combate tem sido realizado por meio de políticas educacionais e legislação própria. A semiótica greimasiana serve de arcabouço teórico por meio do qual discutimos o percurso narrativo do herói negro, com vistas a desvelar sua luta e tornar visível sua identidade histórica e cultural em meio a uma história construída pelo pensamento europeizado.

A dialética de valor de uso e de troca e direcionamentos da ação humana percipiente e propositiva em Mario Ferreira dos Santos
Authors: Veras Murilo Carlos Muniz
Published: March 2018

A percepção dos conhecimentos e a unicidade intrínseca da vontade e da ação humana sempre intrigaram filósofos e cientistas. Mario Santos propõe que a percepção e a expressão da realidade social e econômica na existência concreta dos entes dependem da compreensão de antinomias conceituais, lógico-esquemáticas e ôntico-ontológicas que se complementam dialeticamente. Na economia, o tema “valor”, a antinomia entre valores de uso e de troca, bem como posteriores desdobramentos em diversos outros campos categóricos permitem delinear um direcionador intencional das ações humanas em diferentes cenários da atividade humana, como na propensão a consumir e em configurações de estrutura do mercado de trocas. Propomos ainda que a dialética seja desenvolvida para subsidiar as motivações valorativas de agentes econômicos conscientes.
Lez Play! An Aesthetic Discourse Analysis of Allyson Mitchell’s Ladies Sasquatch
Authors: Lithgow Michael
Published: March 2018

Discourse analysis often overlooks the role of aesthetic experience in the formation of relations of power through meaning. This paper presents an aesthetic discourse analysis of Canadian artist Allyson Mitchell’s Ladies Sasquatch, a celebrated sculpture-installation of six gigantic naked Sasquatches. I argue that by integrating expectations rooted in fine art sensibilities, playfulness and nostalgia into the physical instantiation of an untamed, separatist collective of queer mythological beasts, Ladies Sasquatch tactically uses aesthetic experience—through feelings of uncertainty, anticipation and belonging—to reclaim public space for radical, political lesbian experience. Aesthetic discourse analysis of Ladies Sasquatch demonstrates how aesthetic experience can influence and shape discourse outcomes in the context of resistance to dominant forms of understanding, in this case by challenging the legitimacies of patriarchal norms while destabilizing the ways radical lesbian experience is delegitimized in mainstream cultural contexts.
Miracle Miles, Gender Verification and the Golden Age of Track and Field: Looking Beyond Equity in Elite Athletics in Canada and Abroad
Authors: Hillsburg Heather
Published: March 2018

In 1954, Roger Bannister became the first man to run a mile in under four minutes. Scholars have since identified Bannister’s run as the most significant event in the golden age of track and field. This article explores the various ways we commemorate this era, and maps the intersections between these celebrations, gender verification, inequities in elite track and field, the presence of mythic barriers (that is, time barriers that athletes strive to surpass, and when they do, this becomes important to the history of that sport) in athletics, and the inscription of geopolitical concerns onto the bodies of female athletes. While these phenomenon may seem relatively unrelated, placing gender verification and mythic barriers in conversation with our ideation of track and field’s golden age reveals the racist and sexist scripts that continue to inform elite athletics. This article is guided by two central arguments. First, imagined athletic barriers are male-centred, which erases the accomplishments of female runners, a situation that is reinforced by inequities such as unequal prize money and promotion for female runners. Second, liberal feminist interventions such as demands for equal prize money, promotion, and mythic barriers that women can also attempt to surpass will not lead to equity for female athletes. Rather, equity is only possible if the termination of all forms of gender verification accompanies these strategies. Otherwise, the athletics oval will never become a safe space for women to challenge the imagined limits of their ability.
Staking Claims and Cultivating Local Publics: The Billboards of the Canadian Museum for Human Rights
Authors: Rogers Jaqueline McLeod , Whalen Tracy
Published: March 2018

This article examines a sign campaign posted by the Canadian Museum for Human Rights (2012–2014) in Winnipeg, Manitoba, and the Museum’s strategies for cultivating local publics at a time when its imposing exterior was under construction but its interior was not yet open to public view. Our study reveals that the Museum was more interested in constructing a façade of community goodwill than in responding to or engaging with particular publics and local concerns. Although our analysis concentrates on local details and contexts, it can inform other projects that examine the role of linguistic artifacts and discursive activities in place-forming and -making. We draw on rhetorical, visual, linguistic and critical museum studies to analyze this not-to-be-repeated formative time in a museum’s history, a discursive moment that is both ephemeral and enduring.

: The Atlantic origins of US food safety regulation
Authors: Booker Matthew
Published: March 2018

Food-borne illness remains a major public health problem, with millions sickened annually even in Europe, the United States and other wealthy regions. In the United States, public health authorities contend with limited budgets, criticism from both the political right and left and challenges from both old and new pathogens. Despite their remarkable success in improving the safety of food since the nineteenth century, food regulators struggle with public scepticism and to keep food safe. This paper traces the origins of US food safety regulations to late nineteenth-century exchanges with European governments and consumers and uses the transatlantic oyster trade to illustrate a profound - but still contested - shift in responsibility for food safety between consumers, producers and governmental agencies.
Digesting modernity, healing with nature: The birth of a 'natural' food movement in Meiji Japan, 1905-1910
Authors: Hong Sookyeong
Published: March 2018

This article traces the emergence of a 'natural' food movement in Japan in the first decade of the twentieth century. At the centre of the movement was the Imperial Food Education Society (Shokuikukai, later changed to the Shokuyō Association) led by a former military physician, Ishizuka Sagen. Drawing on nineteenth-century physiological chemistry, Sino-Japanese medicine and the yōjō (nurturing life) tradition from the Tokugawa period, Ishizuka put forth a new dietary program based on the mineral balance between potassium and sodium. By situating these claims on 'right eating through the natural and traditional diet' in the context of the post-Hibiya riot social milieu, this article seeks to probe into the modern cultural nationalism that underpinned this natural food campaign.
Eating tradition: Typical products, distinction and the myth of memory
Authors: Magagnoli Stefano
Published: March 2018

Typical food products today are much more than goods purchased just for taste; often they are bought to indulge symbolic or social behaviours. The concept of 'typicality' appeared well before designations of origin, in pre-industrial times, and was embodied in the goods that had a reputation in the European markets. Over time, these products have come to define deep-rooted relationships with the terroir in which they are made, becoming in this way an important part of the cultural heritage.

This paper uses the concept of 'typical' in a general sense to define a wide range of products that, in other scientific approaches as well as in the lexicon of other European experiences, are sometimes classified as heritage or traditional products. As foodstuffs, they can be described in various ways: local, regional, place-based, GI, authentic and farm products. In this article the concept of 'typical' is used as shorthand for a category that has been widely studied in the past. Like many other fashion goods, the purchase is often the result of decision making by consumers that reflects symbolic ideas rather than rational processes. These choices are numerous and varied, but given the irrational nature of consumer behaviour, they tend to be largely based on symbolic and abstract factors.

With Avatar products - which copy in some ways the 'original' ones - rather than the reality of a typical product, the consumer is offered an illusion in terms of communication and symbol. Such products are often reinvented and, at the same time, they can take on the signs and symbolic values of a so-called authentic typical product. This article presents theoretical reflections and empirical case studies showing that consuming typical products is often an expression of cultural consumption, rooted in a 'myth of memory'.
Melatonin Effects on EEG Activity During Sleep Onset in Mild-to-Moderate Alzheimer’s Disease: A Pilot Study
Authors: Cruz-Aguilar Manuel Alejandro , Ramírez-Salado Ignacio , Guevara Miguel Angel , Hernández-González Marisela , Benitez-King Gloria
Published: March 2018

There is evidence demonstrating that 5-mg of fast-release melatonin significantly reduces nocturnal sleep onset in patients with mild-to-moderate Alzheimer’s disease (AD). However, the physiological mechanism that could promote sleep installation by melatonin in patients with AD is still poorly understood. The present pilot study was designed to analyze the effects of melatonin on cortical activity during the sleep onset period (SOP) in eight mild-to-moderate AD patients treated with 5-mg of fast-release melatonin. Electroencephalographic recordings were obtained from C3-A1, C4-A2, F7-T3, F8-T4, F3-F4, and O1-O2. The relative power (RP), interhemispheric, intrahemispheric, and fronto-posterior correlations of six electroencephalographic bands were calculated and compared between two conditions: placebo and melatonin. Results show that at F7-T3, F3-F4, and C3-A1, melatonin induced an increase of the RP of the delta band. Likewise, in F7-T3, melatonin induced a decrease of the RP in the alpha1 band. Similarly, results show a lower interhemispheric correlation between the F7-T3 and F8-T4 derivations in the alpha1 band compared to the placebo condition. We conclude that the short sleep onset related to melatonin intake in AD patients was associated with a lower RP of the alpha1, a higher RP of the delta band (mainly in the left hemisphere) and a decreased interhemispheric EEG coupling in the alpha1 band. The possible role of the GABAergic neurotransmission as well as of the cascade of neurochemical events that melatonin triggers on sleep onset are discussed.
Listening to the Landscape for an Ecosophic Aesthetic
Authors: Barbanti Roberto
Published: March 2018

Listening to the landscape means hearing the world differently, this article contends. Since its theorization in the pictorial figuration of the fifteenth and sixteenth centuries, landscape has been conceived as a spatial extent delimited by the gaze of a spectator. In the late 1960s a more complex and sensitive approach to landscape, including reflection on its sound and acoustic aspects, began to emerge. Despite this new focus, a certain oculo-centrism still persists. The ecosophical approach — which complicates and goes beyond the antitheses of subject/object, ethics/aesthetics, nature culture — that is put forward here promotes a new aesthetic dimension focused on listening. Based on the notions of presence, holism and non-separation, this approach makes it possible to combine the individual and the collective imagination with social relations and natural processes.
Saro-Wiwa's Language of Dissent: Translating between African Englishes
Authors: Kendall Judy
Published: March 2018

This article calls attention to the essential translational aspect of linguistic experimentation in literary uses of African Englishes in colonial and postcolonial West African literature. It focuses mainly on the literature of the most linguistically diverse country in Africa – Nigeria. Drawing on the theoretical work of Itamar Even-Zohar, Lawrence Venuti, and Pierre Bourdieu, it demonstrates how the different Englishes used in this literature act in a translational way, relating and responding to cultural, political, and social contexts. Specific attention is paid to Amos Tutuola's use of interlanguage and diglossia; Chinua Achebe's manipulation of acts of code-switching and mixing; and how Ken Saro-Wiwa's development of a unique language of dissent in his novel Sozaboy: A Novel in Rotten English is built upon these earlier experimentations with translations between Englishes.
Systems-Level Feedbacks of NRF2 Controlling Autophagy upon Oxidative Stress Response

Although the primary role of autophagy-dependent cellular self-eating is cytoprotective upon various stress events (such as starvation, oxidative stress, and high temperatures), sustained autophagy might lead to cell death. A transcription factor called NRF2 (nuclear factor erythroid-related factor 2) seems to be essential in maintaining cellular homeostasis in the presence of either reactive oxygen or nitrogen species generated by internal metabolism or external exposure. Accumulating experimental evidence reveals that oxidative stress also influences the balance of the 5′ AMP-activated protein kinase (AMPK)/rapamycin (mammalian kinase target of rapamycin or mTOR) signaling pathway, thereby inducing autophagy. Based on computational modeling here we propose that the regulatory triangle of AMPK, NRF2 and mTOR guaranties a precise oxidative stress response mechanism comprising of autophagy. We suggest that under conditions of oxidative stress, AMPK is crucial for autophagy induction via mTOR down-regulation, while NRF2 fine-tunes the process of autophagy according to the level of oxidative stress. We claim that the cellular oxidative stress response mechanism achieves an incoherently amplified negative feedback loop involving NRF2, mTOR and AMPK. The mTOR-NRF2 double negative feedback generates bistability, supporting the proper separation of two alternative steady states, called autophagy-dependent survival (at low stress) and cell death (at high stress). In addition, an AMPK-mTOR-NRF2 negative feedback loop suggests an oscillatory characteristic of autophagy upon prolonged intermediate levels of oxidative stress, resulting in new rounds of autophagy stimulation until the stress events cannot be dissolved. Our results indicate that AMPK-, NRF2- and mTOR-controlled autophagy induction provides a dynamic adaptation to altering environmental conditions, assuming their new frontier in biomedicine.

In mechanical sensory systems, encapsulation is one of the crucial issues to take care of when it comes to protection of the systems from external damage. Recently, a new type of a mechanical strain sensor inspired by spider’s slit organ has been reported, which has incredibly high sensitivity, flexibility, wearability, and multifunctional sensing abilities. In spite of many of these advantages, the sensor is still vulnerable in harsh environments of liquids and/or high temperature, because it has heat-vulnerable polyethylene terephthalate (PET) substrate without any encapsulation layer. Here, we present a mechanical crack-based strain sensor with heat, water and saline solution resistance by alternating the substrate from polyester film to polyimide film and encapsulating the sensor with polyimide. We have demonstrated the ability of the encapsulated crack-based sensor against heat, water, saline solution damage through experiments. Our sensor exhibited reproducibility and durability with high sensitivity to strain (gauge factor above 10,000 at strain of two percent). These results show a new potential of the crack-based sensory system to be used as a wearable voice/motion/pulse sensing device and a high-temperature strain sensor.

Published: March 2018

The arising of domestic robots in smart infrastructure has raised demands for intuitive and natural interaction between humans and robots. To address this problem, a wearable wrist-worn camera (WwwCam) is proposed in this paper. With the capability of recognizing human hand gestures in real-time, it enables services such as controlling mopping robots, mobile manipulators, or appliances in smart-home scenarios. The recognition is based on finger segmentation and template matching. Distance transformation algorithm is adopted and adapted to robustly segment fingers from the hand. Based on fingers’ angles relative to the wrist, a finger angle prediction algorithm and a template matching metric are proposed. All possible gesture types of the captured image are first predicted, and then evaluated and compared to the template image to achieve the classification. Unlike other template matching methods relying highly on large training set, this scheme possesses high flexibility since it requires only one image as the template, and can classify gestures formed by different combinations of fingers. In the experiment, it successfully recognized ten finger gestures from number zero to nine defined by American Sign Language with an accuracy up to 99.38%. Its performance was further demonstrated by manipulating a robot arm using the implemented algorithms and WwwCam to transport and pile up wooden building blocks.

Published: March 2018

Shot peening is an attractive technique for fatigue enhanced performance of metallic components, because it increases fatigue crack initiation life prevention and retards early crack growth. Engineering design based on fatigue crack propagation predictions applying the principles of fracture mechanics is commonly used in aluminum structures for aerospace engineering. The main purpose of present work was to analyze the effect of shot peening on the fatigue crack propagation of the 7475 aluminum alloy, under both constant amplitude loading and periodical overload blocks. The tests were performed on 4 and 8 mm thickness specimens with stress ratios of 0.05 and 0.4. The analysis of the shot-peened surface showed a small increase of the micro-hardness values due to the plastic deformations imposed by shot peening. The surface peening beneficial effect on fatigue crack growth is very limited; its main effect is more noticeable near the threshold. The specimen’s thickness only has marginal influence on the crack propagation, in opposite to the stress ratio. Periodic overload blocks of 300 cycles promotes a reduction of the fatigue crack growth rate for both intervals of 7500 and 15,000 cycles.
Enhancing the Accuracy of Advanced High Temperature Mechanical Testing through Thermography
Authors: Jones Jonathan
Published: March 2018

This paper describes the advantages and enhanced accuracy thermography provides to high temperature mechanical testing. This technique is not only used to monitor, but also to control test specimen temperatures where the infra-red technique enables accurate non-invasive control of rapid thermal cycling for non-metallic materials. Isothermal and dynamic waveforms are employed over a 200–800 °C temperature range to pre-oxidised and coated specimens to assess the capability of the technique. This application shows thermography to be accurate to within ±2 °C of thermocouples, a standardised measurement technique. This work demonstrates the superior visibility of test temperatures previously unobtainable by conventional thermocouples or even more modern pyrometers that thermography can deliver. As a result, the speed and accuracy of thermal profiling, thermal gradient measurements and cold/hot spot identification using the technique has increased significantly to the point where temperature can now be controlled by averaging over a specified area. The increased visibility of specimen temperatures has revealed additional unknown effects such as thermocouple shadowing, preferential crack tip heating within an induction coil, and, fundamental response time of individual measurement techniques which are investigated further.
Nanometric Plasmonic Rulers Based on Orthogonal Plasmonic Gap Modes in Metal Nanoblocks

Published: March 2018

We theoretically propose a three-dimensional (3D) plasmonic ruler based on orthogonal plasmonic gap modes which have different wavelengths. The ruler consists of three silver nanoblocks with two ten-nanometer air gaps. First, in a two-block structure, the lateral displacement of one block can be determined by the absorption spectrum, in which two orthogonal modes are observed with different wavelengths. Secondly, in a three-block structure, due to the distinctive wavelength dependencies on the x- or y-directional movement of the two orthogonal modes and the strong dependencies on the air gap size, the 3D positioning of one nanoblock relative to a reference nanoblock can be measured with a 2.5 nm resolution using the spectral positions of the absorption spectrum.

Tetrahydropyran (THP) represents an O-containing hetero-cyclic compound that can be used as a promising solvent or monomer for polymer synthesis. In this work, Cu–ZnO/Al2O3 catalysts have been prepared by a facile precipitation–extrusion method and used for the synthesis of THP through gaseous-phase hydrogenolysis of tetrahydrofurfuryl alcohol (THFA). The effect of the molar ratio of Cu/Zn/Al, reaction temperature, and hydrogen pressure was investigated. An 89.4% selectivity of THP was achieved at 270 °C and 1.0 MPa H2. Meanwhile, the optimum molar ratio of Cu/Zn/Al was determined to be 4:1:10. The Cu–ZnO/Al2O3 catalyst exhibited high catalytic activity and stability for 205 h on-stream. A possible reaction mechanism involving several consecutive reactions was proposed: THFA was firstly rearranged to 2-hydroxytetrahydropyran (2-HTHP), followed by the dehydration of 2-HTHP to 3,4-2H-dihydropyran (DHP) over acid sites; finally, the DHP was hydrogenated to THP. The synergy of acid sites and metal sites of Cu–ZnO/Al2O3 played an important role during the production of THP.
