A history of abuse
Authors: Weston Samantha
Published: February 2021

The story of the past 30 years has been the relentless hollowing-out of industrial Britain, the single biggest change to the British economy in the post-war era. During this period, whole communities have become destabilised by mass long-term unemployment resulting in discarded generations that have been excluded socially and economically from the benefits widely available to those in work (Hutton, 1996; Buchanan, 2000). It has been against this backdrop that the youth of the 80s and 90s turned to heroin in an attempt to block out the harsh social and economic realities of their lives (Buchanan and Wyke, 1987). Drawing on semi-structured interviews with twelve opiate-involved users (OIUs), this paper illuminates the harms experienced by those who began their drug taking during the 80s and 90s. Particularly, I argue that the negative consequences brought about by the broad umbrella of drug treatment policy that adopts a framework of risk-based strategies designed to regulate and control drug users has had a cumulative effect contributing to further experiences of stigma, unemployment, physical and mental ill health.

Authors: Mhmood Amenah , Zengin Ahmet
Published: February 2021

Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central management. Moreover, every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at uncertain times. There are several familiar routing protocols like AODV, DSR, and DSDV etc. which have been proposed for providing communication among all the nodes in the wireless network. This paper presents a performance comparison and study of reactive (AODV) and proactive (DSDV) protocols based on metrics such as throughput, packet delivery ratio, average end-to end delay, paket loss rate and consumed energy by using the NS-2 simulator. The simulation results showed that AODV performance is better than DSDV regarding packet delivery ratio and end to end delay, while DSDV performance is better than AODV regarding packet loss rate and consumed energy then the performance of AODV and DSDV protocls in throughput parameter is equal close. For small networks, DSDV works well and AODV is best suited for larger networks.

Published: February 2021

Weak-quality curriculum and instruction, educators’ negative views in developing creativity, and a lack of educator flexibility, independency, and well-certified professional development are known as some barriers to implement creative teaching. The present study investigates the convergent, construct and discriminant validity of creative teaching instrument. Moreover, the present study explores the issue of teachers’ creative teaching in Indonesian secondary schools by focusing on types of subject (science and social study). We followed a survey research design, using simple random sampling. A total of 150 students, which comprise 65 (43.3%) science teacher (physics, chemistry, mathematics, biology)) and 85 (56.7%) social science teacher (economics, geography, English, Indonesian language, sociology) in secondary school, have finished the questionnaire. The 30 (20%) are male teachers, 120 (80%) are female teachers. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and one-way multivariate analysis of variance (MANOVA) are carried out to analyze the data sample. EFA showed that the teachers’ data included a six-factor structure: instructional designs; curiosity; creative thinking; imaginative utilization; problem solving; and excursion. The outputs of secondary-order CFA indicated that the hypocritical model provided an suitable fit to data sample. Finally, results of the present study reveal a not significant difference in creative teaching among groups. However, significant differences of imagination sub constructs were observed between science and social science teachers.

Published: February 2021

Land suitability assessment is an essential step for the planning and development of land use. This study aims to determine suitable lands for organic farming using an integration of the Geographic Information System and the Decision-Making Trial and Evaluation Laboratory method. Geographic Information System is a flexible and practical framework to assess and map the different criteria, including climatic factors, internal soil characteristics, and topographic features. The Decision-Making Trial and Evaluation Laboratory method is employed to identify the weights of the proposed factors. We investigated the data of 126 soil profiles covering 23220 hectares of land, located in Tamdao district, Vinh Phuc province, in the north of Vietnam. The results revealed that the proportion of land currently highly suitable for organic farming is 25.93% (6020.22 hectares), while the amount of land that is marginally suitable is 6.38% (1481.82 hectares). The amount of land that is moderately suitable for organic farming is 67.69% (15718.08 hectares). Therefore, the proposed method can improve planning and decision-making regarding land that is suitable for cultivation. Future research may deal with a more significant number of selected criteria with different methods, such as Entropy, Analytic Hierarchy Process, and CRiteria Importance Through Intercriteria Correlation to increase this model's power. This study can offer decision-makers insight to understand cause-effect relationships and select suitable sites for other research fields.

Published: February 2021

The notion of the sub-exact sequence is the generalization of exact sequence in algebra, particularly on a module. A module over a ring R is a generalization of the notion of vector space over a field F. A Hilbert space refers to a special vector space over a field F when we have a complete inner product space. The space is complete if every Cauchy sequence converges. Now, we introduce the sub-exact sequence on a Hilbert space, which can be useful later in statistics. This paper is aimed at investigating the properties of the sub-exact sequence and their ratio to direct summand on a Hilbert space. As the result, we obtain two properties of isometric isomorphism sub-exact sequence on a Hilbert space.

Published: February 2021

This article describes a new idea called AMiBI. It is a mitigation platform based on the fact that flood still becomes an annual problem in Indonesia. According to the National Disaster Management Agency or Badan Nasional Penanggulangan Bencana (BNPB), 649 flood incidents occurred from 2011 until 2019 in Indonesia. Natural factors are certainly not the only main factors causing it. Environmental damage plays a more crucial role. One of the causes of this damage is the existence of settlements along the riverbanks. This factor exactly should be controlled by humans. Still, economic needs have become the main reason driving people to survive in big cities by establishing illegal settlements along riverbanks. Regarding these facts, AMiBi was also built under statistical analysis by modeling the flood incidents based on the number of settlements along riverbanks using the local linear nonparametric regression. Its result shows that the model has R2 value of 51.48% and a Mean Square Error (MSE) of 24.26. It also performs a linear relationship between those variables, which means that the existence of settlements along riverbanks significantly affects the number of flood incidents. Regarding those analyses as the basis of development, this digital platform performs several services for reducing loss potency caused and supporting the awareness to build a sustainable environment in riverbanks. Considering AMiBI as the only platform that uses statistical modeling as the basis of services and implementation, it has a significant role in supporting Indonesia as a smart country for mitigation.

Published: February 2021

Lightweight materials are widely used in industry for thermal insulation of various thermal units. The choice of lightweight material depends on the specific conditions of service. For the lining of high-temperature units operating in reducing environments, alumina lightweight products are used that contain a minimum amount of Fe2O3 impurities and free (unbound in compounds) SiO2.

In JSC “URIR named after A. S. Berezhnoy” a technology of alumina lightweight products of grades KLA-1.1 and KLA-1.3 by a semi-dry pressing method with an application temperature of up to 1550 °C has been developed. These products are made from a mixture of ground and no-milled γ-form alumina of grade 0 and α-form alumina of grade S with additives of pitch coke and chalk.

The work purpose was improvement of the alumina lightweight products technology and search for new alternative raw materials along with the currently used alumina grade S. The properties dependence of alumina lightweight products, obtained by the semi-dry pressing method, on the type of alumina α-form, was investigated.

As a result of the studies, it was found that, for the manufacture of alumina lightweight products of grades KLA-1.1 and KLA-1.3 by the semi-dry pressing method, alumina grades N and NR can be used as an alternative alumina-containing raw material along with alumina grade S. The phase composition of alumina lightweight products of grades KLA-1.1 and KLA-1.3, which are manufactured using alumina grades S, N and NR, was represented mainly by corundum and calcium hexaluminate. The alumina lightweight products, which were manufactured using alumina grades S, N and NR, were characterized by similar high properties and correspond the technical requirements for grades KLA-1.1 and KLA-1.3.

Published: February 2021

The paper considers the resource and energy saving reserves in the production of large-format stoneware slabs. The possibility of replacing high-quality feldspars with materials of technogenic origin, such as the extraction and processing waste of various feldspar-bearing rocks of domestic deposits has been investigated. The possibility of sintering process intensification has been investigated, as a condition for the use of high-speed firing modes in the stoneware production. As a result of the carried out studies, the kinetic features of ceramic masses sintering with alkaline syenites, granites and pegmatite enrichment wastes as fluxing component were determined. The formation conditions of densely sintered materials with a complex of high operational properties have been determined. The expediency of replacing Turkish feldspars with waste products of alkaline syenites has been established, while the level of physical, mechanical and operational properties of stoneware slabs meets the requirements of international standards. It is shown that, the use of complex flux, including feldspar-bearing rocks waste and dolomite, provides a significant decrease in the firing temperature of products (up to 1150 °C) while maintaining a high level of properties of stoneware slabs of class BІa. The obtained data indicate the possibility of optimizing the heat treatment parameters from the view point of energy saving with the further use of alternative fluxes in the large-format stoneware production. On the example of using the alkaline syenites wastes, the optimal ratios of the clay and fluxing components of ceramic masses have been established to obtain products with a complex of high performance characteristics when burning white clays of different chemical and mineral composition, which is a necessary condition for using a wide range of decorating techniques stoneware slabs. The structural-phase features of materials obtained under the conditions of high-speed firing are established: the formation of finely dispersed acicular mullite, which plays the role of a reinforcing component, as well as high structural homogeneity and maximum compaction, as evidenced by a few individual small pores presence. The combination of excellent technical qualities and large dimensions opens up new possibilities for the use of stoneware slabs as structural elements (countertops, ventilated facades, insulating panels for the installation of electrical systems, etc.).

Published: February 2021

A review of foreign and native publications on the use of man-made raw materials, which is formed during the extraction and processing of rocks, in the silicate materials production was presented. It was shown that, the disposal of large-scale industrial waste from mining and ore processing industrial complexes is promising for solving environmental problems and expanding the raw material base of silicate industries. An increase in the waste consumption degree will contribute to the integrated use of mineral raw materials, as well as a decrease in the volume of their accumulation and an improvement in the environmental situation. A literature review has shown the obvious potential of waste as an alternative raw material for partial or complete replacement of traditional raw materials in various silicate industries. On the example of artificial stone, stone casting, cement, concrete, ceramic bricks and tiles production, the technologies of silicate materials and products were considered, where waste disposal is technologically sound and economically feasible. It was shown that, mineral technogenic raw materials (wastes from mining, mechanical processing and enrichment of rocks) are used as a concrete, artificial stone and other composite binder’s filler, as non-plastic and fluxing components of ceramics bodies, and even as the main raw material in the production of stone casting. On specific examples, it was considered how a reasonable rocks waste use in the silicate materials production can improve the products properties. Requirements were formulated and criteria for the applicability of stone mining and stone processing waste in the silicate materials production were determined, consideration of which will reduce the hazards and risks associated with the possible presence of technologically harmful and potentially hazardous substances in waste. Knowledge of the using peculiarities wastes from the extraction and processing of the different rocks will allow to optimize technological processes when replacing natural raw materials with technogenic materials. Providing scientific and technical information on the advantages of using waste in the ceramic, glass-crystalline, binders and composite materials production will contribute to the development of resource-saving environmentally friendly technologies, natural resources rational use and increase of industrial enterprises responsibility to society and nature.

Published: February 2021

This paper examined the relationship between FDI, imports, exports, terms of trade and investment   in Pakistan for the period 1990-2015. Results show that an increase in all these factors will contribute significantly to FDI flows that may help the Pakistan’s economy.  FDI has negative and significant impact on GDP.  Exports have an insignificant effect that may imply that historically economy had led exports more than the exports led the economy.  More important fact is that world economic conditions play a crucial role in the macroeconomic performance. When these conditions are favorable, not only the economy but also the trade grow. Though global financial crisis did not seriously affect Pakistan’s economy, Pakistan faced multifaceted challenges on external and internal fronts notably fight against extremism, energy crisis and uncertain external inflows. There is a need to pay more attention to domestic situation than to look abroad for financial assistance since FDI is not an unmixed blessing.

Published: February 2021

Climate change remains one of the world’s greatest challenge in the 21st century. It causes inevitable changes that alter human activities. Adaptation to climate change creates and at the same time limits opportunities that support human existence. While United States of America, Europe, China, India and other countries are maximizing the opportunities climate change adaptation offers especially in areas of green technology, energy and agriculture, that of Africa who are more vulnerable to climate change are complacent and at most show less commitment. As the negative impacts of climate change increases and livelihoods erode, and as jobs continue to disappear leading to conflicts and upheavals in Africa, governments across the continent need policy options that will enable them to mitigate and adapt to climate change while at the same time address the problem of unemployment and create new patterns of livelihood. This paper, therefore, explores options that support these objectives. It offered policy suggestions in green energy and agriculture where Africa have a comparative advantage over other nations, and which also has the capacity of employing 90 per cent of the continent's workforce. It makes suggestions on how Lake Chad and other water sources affected by climate change in Africa can be revived to support agricultural activities and hydropower industry as well as create green jobs. It advocated for investment in biofuel, wind and solar energies to create green jobs. The paper submits that if green jobs are created and agricultural activities supported conflicts associated with unemployment and migration will be reduced drastically.

O Brasil é hoje um dos grandes produtores de alimentos orgânicos. O consumo desse tipo de alimento no país cresce à taxa anual de 25%, e o mercado de feiras específicas é espaço fundamental para esse avanço. Em Belo horizonte, MG, a partir do ano de 2002, foram instaladas oito feiras orgânicas, em três regiões do município. O trabalho teve como objetivo o levantamento do histórico, das características, do perfil dos agricultores feirantes e do perfil dos consumidores dessas feiras. Buscou-se, também, analisar os gargalos para a expansão da produção e comercialização dessas feiras. O estudo foi realizado por meio de observações in loco e de entrevistas com o uso de questionários semiestruturados. Realizaram-se 214 entrevistas com consumidores frequentadores das oito feiras, além de cinco entrevistas com agricultores feirantes e uma entrevista com o supervisor das feiras, funcionário da Prefeitura Municipal de Belo Horizonte. Verificou-se que os agricultores enfrentam dificuldades quanto à disponibilidade de mão de obra e à regularidade da produção, para o atendimento às expectativas de consumidores. A maioria dos consumidores era composta por mulheres com idade entre 30 e 54 anos, com nível de escolaridade elevado e renda mensal equivalente a um valor entre 9 e 12 vezes o salário mínimo brasileiro. As feiras foram consideradas como importantes canais de comercialização da produção orgânica, pois aproximava os agricultores e os consumidores, possibilitando o estabelecimento de relações de confiança entre esses atores.

O presente estudo teve por objetivo a construção de indicadores econômicos sobre a implantação do eucalipto no estado de Goiás. Para tanto, foram calculados e discutidos indicadores como valor presente líquido (VPL), relação benefício/custo (BC), análise de sensibilidade e aplicação do payback econômico do capital investido. A fim de observar o efeito da viabilidade do cultivo diante de situações inesperadas, também foram estimados os impactos para a cultura em quatro cenários que envolveram o projeto. Os resultados indicaram que, para a taxa de desconto de 6,5% a.a., o VPL foi de R$ 14.298,93 para 1 ha, mostrando que o investimento é viável. A relação BC foi maior que 1 (BC > 1), demonstrando que os benefícios da implantação superaram os custos, e o período de tempo que será cursado até o retorno do investimento inicial demonstrou que o retorno para 1 ha a 6 ha se dará no sétimo ano. Da mesma forma, verificou-se que, para todos os cenários estimados, houve viabilidade econômica para a implantação da cultura.

A cerveja é considerada uma das bebidas mais populares entre as que são consumidas mundialmente, perdendo somente para água e café. Ela é produzida por meio da fermentação do mosto cervejeiro proveniente do malte da cevada, e água potável por incremento da levedura e adição do lúpulo. Para fabricar uma boa cerveja, é necessária uma excelente técnica de criação – o sabor e o aroma da cerveja estão diretamente ligados às leveduras escolhidas. Atualmente, cepas de Saccharomyces cerevisiae são utilizadas nos processos de produção. Essas culturas selecionadas tendem a aperfeiçoar o processo e a intensificar a qualidade da matéria-prima. São imprescindíveis as análises da fabricação durante o processo. É importante a realização do teste de iodo de modo a verificar se todo o açúcar foi convertido. Após a maturação, é fundamental analisar o teor alcoólico, pois esse indica a porcentagem de álcool presente na amostra. As análises de densidade, pH, cor, turbidez e contagem de células também são essenciais, já que auxiliam na verificação da qualidade da cerveja. O presente artigo tem como objetivo realizar uma revisão de literatura com ênfase na fabricação da cerveja e nas principais análises necessárias para garantir a qualidade do produto durante o processo, bem como a qualidade final.

O objetivo deste trabalho foi comparar os aspectos agronômicos e produtivos do abacaxizeiro cultivado em sistema orgânico com o cultivado em sistema convencional. Os sistemas de produção de abacaxi requerem a adoção de práticas alternativas e mais sustentáveis, que promovam melhorias socioeconômicas e maior rentabilidade. Utilizou-se o delineamento experimental de blocos casualizados com quatro repetições e cinco tratamentos (T). Os tratamentos foram: T1 – aplicações de biofertilizante a cada 7 dias; T2 – aplicações de biofertilizante a cada 14 dias; T3 – aplicações de biofertilizante a cada 21 dias; T4 – aplicações de biofertilizante a cada 28 dias; e T5 – adubação química. Em cada aplicação, foram adicionados 100 mL de biofertilizante por planta. O comprimento e a massa do caule do abacaxi aumentaram de forma linear com a aplicação do biofertilizante. Porém, a quantidade de sólidos solúveis apresentou correlação negativa com as aplicações de biofertilizantes. De forma geral, os aspectos vegetativos e produtivos do abacaxizeiro produzido tanto em sistema orgânico quanto em convencional foram similares. Assim, pode-se recomendar o uso de biofertilizantes aeróbicos como alternativa para a produção orgânica do abacaxi Pérola.

A partir do momento em que o homem começou a utilizar superfícies com movimento relativo, ele empenhou-se na busca de métodos para reduzir o atrito e, consequentemente, o desgaste. Sempre em busca da maior redução do atrito, cientistas trabalham no desenvolvimento de novas tecnologias que sejam capazes de reduzir o desgaste e, ao mesmo tempo, permitam o desenvolvimento sustentável. Entre os elementos utilizados para a redução do atrito, podem-se destacar os lubrificantes, as graxas, o acabamento superficial, e o uso de revestimentos e aditivos. Entretanto, para que novos produtos, como biolubrificantes, biocombustíveis e aditivos, sejam aplicados no mercado, é necessário realizar ensaios experimentais, que avaliem as propriedades tribológicas nas aplicações desejadas. Como existem vários ensaios tribológicos disponíveis, o pesquisador deve selecionar aquele que mais se adapta às suas necessidades e escolher os parâmetros que se assemelhem à aplicação requerida. A depender da escolha, pode haver interpretações errôneas dos resultados. Dentro desse contexto, o presente trabalho buscou reunir os principais ensaios de tribologia utilizados, apresentando suas finalidades e os principais parâmetros avaliados, permitindo, assim, ao leitor, uma introdução aos conceitos de lubrificação e ao conhecimento dos ensaios de lubricidade.
A agrobiodiversidade e seu papel em relação à variabilidade e aos recursos genéticos em pimenta Capsicum chinense
Authors: Martha Anderson Luis Mesquita da
Published: February 2021

Nas últimas décadas, a biodiversidade vem passando por um processo de degradação sem precedentes na história humana, por causa de um modelo superado de exploração. A agrobiodiversidade faz parte da biodiversidade, mas tem uma visão contrária àquele modelo, ao buscar interagir com os inúmeros ecossistemas e formas de produção. As pimentas, conhecidas mundialmente entre as especiarias picantes, e importante componente da agrobiodiversidade do nosso país, vêm sendo substituídas por outras opções de cultivo. Visando à conservação da diversidade genética das pimentas no Sul do Brasil, a Embrapa Clima Temperado mantém, desde 2002, um Banco Ativo de Germoplasma (BAG) de pimentas do gênero Capsicum. O objetivo do trabalho foi descrever a variabilidade genética de frutos de pimenta da espécie Capsicum chinense, como forma de documentação para o Banco Ativo de Germoplasma (BAG) da Embrapa Clima Temperado. Para isso, 11 acessos de pimenta do BAG de Capsicum da Embrapa Clima Temperado foram caracterizados, utilizando-se descritores morfológicos recomendados pelo International Plant Genetic Resources Institute.
