Authors: Cao Yuhong , Liu Meiyun , Cao Yuandan , Chen Chen , Zhang Dapeng
Published: July 2020

The construction land includes the urban land, rural residential areas and other construction land. The Wanjiang City Belt along the Yangtze River is an important demonstration area for undertaking industrial transfer in China. With the accumulation of factors relative to economic development, the construction land has increased sharply, and the regional ecological security pattern is facing new challenges. After collecting the image interpretation data of multi-period land use of the Wanjiang City Belt, the work studied the characteristics of construction land change pattern since 1995 and its driving mechanism based on the GIS platform, land use transfer matrix, expansion intensity index, hotspot analysis and mathematical statistics. The results showed that: (1) From 1995 to 2015, the urban land and other construction land in the Wanjiang City Belt have increased, but the rural residential areas decreased in 2010-2015. The three types of land had the largest changes in 2005-2010 and the change in the other construction land was particularly prominent. (2) The hotspots for construction land expansion are mainly in urban areas with rapid economic development such as Hefei, Wuhu, Ma’anshan and Tongling, where the land use changes most severely. (3) The driving factors for the change of construction land area include natural and social factors. Among social and economic factors, the GDP, industrial added value, secondary output value and urbanization rate are the main driving forces for changes. In the past 20 years, the construction of China’s Undertaking Industrial Transfer Demonstration Area has changed the land optimal allocation and intensive use mode in the region, providing the basis for resource development and utilization, economic development and industrial structure adjustment.
Consolidation and Deformation Characteristics of Soft Rock Foundation in Hydrological Wetland Environment
Authors: Liu Bin , Jiang Xiugen
Published: July 2020

The widespread distribution of soft rock and soft soil in hydrological wetland environment is a common geotechnical engineering problem encountered in coastal engineering construction. To solve this problem, a study method for consolidation and deformation characteristics of soft rock and soft soil foundation in hydrological wetland environment is proposed. Taking K9+280-K11+120 section along Fu-Nehe section of National Highway 111 as the research object, the consolidation and deformation characteristics and loading conditions of soft soil foundation under embankment filling load, treatment methods of soft rock foundation, stratum conditions, temperature changes and time effects are analyzed. The results show that although the wetland soft rock and soil layer is not thick, the settlement of soft rock and soil accounts for more than 80% of the total settlement. Negative temperature has a certain influence on the consolidation settlement of soft rock foundation, which is mainly manifested in the difference between the settlement process of the central separation zone and the roadbed soft soil foundation; the pore water pressure of soft rock foundation dissipates to varying degrees. According to the monitoring results of settlement and pore water pressure, bagged sand wells are more suitable for soft rock foundation engineering treatment in hydrological wetland. The research results can provide a reference for the study, calculation and design of consolidation and deformation of soft rock foundation in hydrological wetland.
Heterogeneous Catalytic Ozonation of Phenol over Iron-based Catalysts in a Trickle Bed Reactor
Authors: Briceño Mena Luis , Durán Herrera Esteban
Published: July 2020

The use of continuous reactors for heterogeneous catalytic ozonation is yet to be investigated in order to develop a viable technology for industrial applications. This paper presents hydrodynamic and degradation studies on the use of a co-current down flow trickle bed reactor for heterogeneous catalytic ozonation of phenol (as model pollutant) over Fe-Diatomite pellets and Fe-coated glass beads. It was found that the reactor can operate under trickle or pulsing flow regimes, promoting mass transfer augmentation. Residence time distribution data, fitted with n-CSTR and axial dispersion (ADM) models, showed low axial dispersion and high flow distribution. Just the Fe-diatomite pellets showed important phenol adsorption (16 %). Degradation experiments demonstrated that phenol conversion was substantial when using both catalysts, up to 19,7 % pollutant conversion with liquid-phase space times of just 6 s. Compared to direct ozonation, the use of the Fe-diatomite pellets and Fe-coated glass beads enhanced the reactor performance by 48 % and 23 %, respectively. It was confirmed that mass transfer is an important factor that restricts this reaction system performance; consequently, further improvement in mass transport rate is necessary for system optimization.

Authors: Ajadi R. A. , Sanni J. L. , Sobayo E. F. , Ijaopo O. K.
Published: July 2020

Changes in plasma concentrations of trace elements and oxidants/antioxidants were evaluated in twenty healthy Boerboels of both sexes and median age of 2 years. Antero-posterior and flexed lateral radiographs of the hip were obtained using digital x-ray machine and hip grading was done according to Fédération Cynologique Internationale (FCI) system. Blood was collected from the cephalic vein for determination of plasma concentrations of manganese (Mn), magnesium (Mg), copper (Cu), cobalt (Co), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GPX) and Vitamin E. Correlation between the parameters was done using Pearson’s correlation. Eleven (11/20) of the Boerboel dogs had hip dysplasia (HD), comprising five (5/9) males and six (6/11) females. Plasma Mn, Cu and Co were insignificantly higher in Boerboels with normal hips than those with HD. MDA concentration was significantly (p<0.05) lower in Boerboels with normal hips (0.75 ± 0.84 µmol/L) than in dogs with HD (1.77 ± 0.78 µmol/L), while SOD was significantly (p<0.05) higher in Boerboels with normal hips (0.65 ± 0.22 U/ml) than with HD (0.32 ± 0.16 U/ml). It was concluded that there were differences in plasma oxidants/antioxidants between Boerboel dogs with normal hips and those with hip dysplasia suggesting their role in the pathogenesis of canine hip dysplasia
Cohesion coefficient of structural concrete made with recycled concrete coarse aggregate
Authors: Sahoo Dipak Kumar , Mathew Praveen
Published: July 2020

The cohesion coefficient of structural concrete made with recycled concrete coarse aggregate (RCA) was evaluated independently for the first time, through push-off tests having no clamping force across the shear plane, and compared with the cohesion coefficient of structural concrete made with natural coarse aggregate (NCA). Both conventionally compacted and self-compacting concretes were made with RCA and NCA as coarse aggregates. To achieve the best structural quality, concretes made with RCA were proportioned based on the equivalent mortar volume (EMV) principle instead of percentage replacement of NCA with RCA commonly followed in most of the earlier studies. Twelve transversely unreinforced push-off specimens, three from each of the four varieties of concrete, were tested to failure. Cohesion coefficients determined from analytical and finite-element modelling of the push-off tests were found to be in close conformity with each other, and the experimentally found cohesion coefficients were reasonably close to, though not in exact conformity with, the theoretical values. Nevertheless, the experimental results clearly established that RCA concrete when proportioned by the EMV method is not inferior to NCA concrete in terms of cohesion contribution to shear strength.

Published: July 2020

Objetivo Describir cómo los estudiantes universitarios razonan funcional y causalmente sobre un ecosistema, usando el modelo estructura, comportamiento y función. Método: Se acoge un diseño transversal descriptivo, con un modelo mixto de triangulación concurrente; simultáneamente se recolectaron y analizaron datos cualitativos y cuantitativos para compararlos e integrarlos. A partir de muestreo intencional con estudiantes universitarios (n=60) se conformaron cuatro grupos: estudiantes de Biología y de Licenciatura en Ciencias Naturales y Educación ambiental. Los participantes se dividieron en cuatro grupos equitativos, de acuerdo a la carrera y a la condición de haber cursado o no durante el 2018 dos asignaturas obligatorias del currículo relacionadas con la ecología. Ellos respondieron una entrevista sobre ecosistemas y resolvieron una situación problema planteada en un bioterio afectado por actividades antropogénicas y residuos contaminantes. Resultados Se encontraron diferencias atribuibles al nivel de experticia entre los estudiantes de la carrera biología que cursaron ecología, quienes comprendieron el ecosistema desde la interdependencia dinámica de la estructura y las funciones, frente a otros grupos, que enfatizaron en los componentes estructurales con mayor saliencia perceptual. Conclusiones y discusiones Aunque la mayoría de los estudiantes comprenden las relaciones causales y funcionales del ecosistema, existen algunos sesgos en la construcción conceptual, los cuales pueden ser explicados desde el reconocimiento incorrecto de la causa y el establecimiento de relaciones causales.

Las mujeres bertsolaris, agentes en su incorporación a la escena pública
Authors: Lasarte Leonet Gema , Vizcarra Morales María Teresa , Perales Fernández de Gamboa Andrea , Fernández Rodríguez Vanesa
Published: July 2020

El bertsolarismo se asocia con lo masculino y con lo público. Más exactamente con la plaza, lugar hegemónico de la cultura vasca (González Abrisketa, 2013), donde se juega a la pelota, hablan los políticos e improvisan y cantan los bertsolaris. La improvisación oral fue durante siglos práctica natural de las mujeres y de los hombres vascos, pero con los cambios acaecidos en el siglo XIX, que primaron los lugares públicos –la plaza- en lugar de los interiores, las mujeres se retiraron hasta casi desaparecer. No del todo, porque tímidamente se abrieron camino en ese mundo de hombres. Este trabajo teoriza sobre las voces subalternas; sobre el empoderamiento de las mujeres bertsolaris, que pasaron de invisibles a notorias. También de agency, indispensable en el empoderamiento de las mujeres (Murguialday, 2013; León, 2013). Para averiguar la irrupción de las bertsolaris hasta la adquisición de la agencia en las últimas décadas, se pasaron 200 cuestionarios a dichas mujeres y se realizaron, asimismo, entrevistas con 36 de las personas encuestadas.

Published: July 2020

The peculiarities of financial audits conducted by the Accounting Chamber of Ukraine according to a methodology that meets the requirements of ISSAI are explored. The Financial Audit Manual with detailed instructions, audit procedures, and templates of audit documentation, elaborated by the Accounting Chamber and international partners in 2019, is considered.

The analysis of the experience of 31 European SAIs showed that most of SAIs do not publish audit manuals, in particular, only SAI of Albania, Georgia, Lithuania, Moldova, and Romania provided free access to financial audit manuals. The methodological recommendations for conducting the financial audit by the Accounting Chamber of Ukraine, adopted and published in 2015, cover all the issues that are outlined in such manuals of SAIs from those countries..Besides, the risks of providing open access to the Financial Audit Manual, elaborated by the Accounting Chamber of Ukraine were detected. They are the risks of fraud by officials of audited entities, not detecting a material risks by auditors, the use of intellectual property of the Accounting Chamber for commercial purposes by other entities and reputational risks due to breach of agreements with international partners involved in the development of the manual.

The Financial Audit Manual was tested on six financial audits conducted by the Accounting Chamber in 2019 and main results are analyzed in the paper. Significant deficiencies of internal control, fraud risks and risks associated with accounting, budgeting and financial reporting software, and the need of improvement in accounting policies, internal control and workflow in all audit entities were identified. Additionally,, the audit results are presented in a user-friendly format tailored to the needs of decision- makers, with an emphasis on issues that require rapid response. Based on the conducted analysis, the conclusions about the low quality of financial and budgetary reporting of public sector entities and the systematic nature of identified problems and risks were made. Thus, the importance of financial audits was emphasized and the proposals for further improvement of this type of audit of the Accounting Chamber were elaborated. In particular, updating of the legislation and internal documents, usage of modern information technologies and software for audits, translation of ISSAI, training for staff, changes in personnel policy, improvement of the quality control system.

Annexins and their role in the control of symbioses development in plants
Authors: Kustova Darya V. , Dolgikh Elena A.
Published: July 2020

Annexins belong to the superfamily of calcium-dependent phospholipid binding proteins. The participation of these proteins in the regulation of structural organization of membranes, vesicular transport and a variety of signal transduction pathways is important for many cellular processes. Despite the structural similarity with animal annexins, plant annexins are characterized by significant variability of the N-terminal region and modification of calcium-binding motifs in II and III repeats, while calcium-binding motifs in I and IV repetitions remain conservative. However, the physiological role of animal and plant annexins, as well as mechanisms of their influence on calcium metabolism, may be similar. This review focused on the latest data about the structure and functioning of plant annexins.

Background. Active ribosomal genes and DNA repair genes play an important role in restoring genome integrity. Therefore we were studied relationship of active ribosomal genes dose and DNA repair genes polymorphisms with high level of chromosomal disorders in miners.
Materials and methods. The DNA damage level was assessed using chromosomal aberrations (CA) at 288 coal miners and 676 men in the control group. The dose of active ribosomal gene (AcRG) has been analyzed using Ag-NORS staining regions of chromosomes and cytogenetic semi-quantitative evaluation method. Real-time PCR and allele-specific PCR techniques were used to analyze polymorphic variants of the XPG (rs17655), XPD (rs13181), XRCC2 (rs3218536), and XRCC3 (rs861539) genes.
Results. A statistically significant (p = 0.0001) increase of the СА level at miners was found in comparison with the control group. The association XPD 2251TG locus with increasing CA level is revealed of in recessive inheritance model (padj = 0.0001). The association XPG 3310GC locus with increasing СА level is revealed at the smoking workers (padj = 0.017). An average dose of AcRG was registered a statistically significant increase in the frequency of single fragments (p = 0.016) at the miners.
Conclusion. The obtained data on associations of chromosomal aberrations with different variants of DNA repair genes and the dose of active ribosomal genes are useful for the formation of high-risk groups.

Objetivou-se determinar os parâmetros fisiológicos de equinos atletas de vaquejada e avaliar o emprego da termografia infravermelha como ferramenta de auxílio ao diagnóstico precoce de lesões musculoesqueléticas decorrentes do treinamento físico desses animais. Foram utilizados 10 animais atletas da raça Quarto de Milha, machos e fêmeas, com idades entre 5 e 15 anos. Os animais foram divididos em dois grupos: animais da categoria puxada (G1) e animais da categoria esteira (G2). Foram determinados: frequência cardíaca (FC), frequência respiratória (FR), temperatura retal (TR), tempo de preenchimento capilar (TPC), movimentos intestinais e coloração das mucosas. Temperatura superficial (TS) foi obtida por meio da realização de projeções de cada animal com câmera termográfica FLIR® T10611. As variáveis foram mensuradas em três momentos: antes do treino (AT), imediatamente após o treino (PT) e duas horas após o treino (2h PT). As variáveis climáticas foram mensuradas com Data Loggers Hobo®. O índice de conforto térmico (IC) indicou que os animais se encontravam em conforto térmico durante os momentos avaliados. O esforço físico foi suficiente para causar alterações em alguns dos parâmetros avaliados: FC, FR, TR e TS. Na avaliação das termografias, observou-se um aumento da temperatura local na região de músculo semitendinoso em um dos animais avaliados. A utilização da câmera termográfica pode contribuir para a prevenção e para o diagnóstico precoce de lesões musculoesqueléticas de equinos de vaquejada.

Authors: Dalcero Kátia , Ferreira Denize Minatti
Published: July 2020

A ecoeficiência verifica a integração dos fatores econômicos e ambientais nas organizações, buscando a utilização adequada dos recursos para maximizar resultados econômicos. O objetivo do presente estudo é comparar o índice de ecoeficiência das empresas listadas na [B]3 (Brasil, Bolsa, Balcão) consideradas potencialmente poluidoras e utilizadoras dos recursos naturais, conforme o Anexo VIII da Lei Federal nº 10.165/2000, que trata sobre a Política Nacional do Meio Ambiente. Para determinar a relação dos indicadores econômicos e ambientais e para o cálculo do índice de ecoeficiência das empresas que compõem a amostra da pesquisa, utilizou-se a Análise Envoltória de Dados (DEA). Foi verificada, ainda, a relação entre as variáveis por meio do cálculo da correlação de Pearson. Os resultados apontaram que a maioria das empresas analisadas possuía, no período de 2012 a 2017, nível alto de ecoeficiência, exceto algumas dos setores de transporte e de papel e celulose, que apresentaram índices de ecoeficiência muito baixos. Também foi analisada a correlação das variáveis que compõem o modelo do cálculo de ecoeficiência, ficando demonstrado que todas as variáveis apresentaram significância para a explicação do modelo. Além disso, verificou-se que a variável “lucro bruto” apresenta correlação positiva com o índice de ecoeficiência, enquanto as demais variáveis (emissões de gases de efeito estufa (GEE), consumo energético, consumo hídrico e resíduos) apresentam relação negativa com esse índice.

Primary health care policy and vision for community pharmacy and pharmacists in Portugal
Authors: Ribeiro Nadine , Mota-Filipe Helder , Guerreiro Mara P. , Costa Filipa A.
Published: July 2020

The central role of the Portuguese National Health Service (P-NHS) guarantees virtually free universal coverage. Key policy papers, such as the National Health Plan and the National Plan for Patient Safety have implications for pharmacists, including an engagement in medicines reconciliation. These primary health care reform, while not explicitly contemplating a role for pharmacists, offer opportunities for the involvement of primary care pharmacists in medicines management. Primary care pharmacists, who as employees of the P-NHS work closely with an interdisciplinary team, have launched a pilot service to manage polypharmacy in people living with multimorbidities, involving potential referral to community pharmacy. Full integration of community pharmacy into primary health care is challenging due to their nature as private providers, which implies the need for the recognition that public and private health sectors are mutually complementary and may maximize universal health coverage. The scope of practice of community pharmacies has been shifting to service provision, currently supported by law and in some cases, including the needle and syringe exchange program and generic substitution, remunerated. Key changes envisaged for the future of pharmacists and their integration in primary care comprise the development and establishment of clinical pharmacy as a specialization area, peer clinician recognition and better integration in primary care teams, including full access to clinical records. These key changes would enable pharmacists to apply their competence in medicines optimization for improved patient outcomes.
Impacto da crise econômica de 2015-2016 sobre o coeficiente beta do mercado de capitais brasileiro
Authors: Nonato Vinícius , Tófoli Paula
Published: July 2020

Estudos empíricos têm encontrado evidências de que o risco de mercado, ou beta de mercado, tende a aumentar em períodos de crise. Dada a crise econômica brasileira de 2015-2016, o objetivo deste artigo é analisar se esta teve um impacto significativo sobre o risco de mercado das empresas brasileiras com ações negociadas na bolsa de valores brasileira (B3). Para isso, estimamos a trajetória do beta de uma carteira de ações negociadas na B3 para o período de fevereiro de 2010 a dezembro de 2018, considerando um modelo CAPM condicional em que a dinâmica de beta é dada por um processo estocástico combinado com um conjunto de variáveis condicionantes relacionadas ao ciclo econômico. Encontramos evidências de que o beta da carteira teve um aumento a partir de janeiro de 2015 e só retornou a patamares do período pré-crise a partir de março de 2018. Essas evidências estão de acordo com os resultados encontrados na literatura internacional e têm implicações importantes em termos de gerenciamento de risco.

Hace algunos años, el diagnóstico de la tuberculosis genital era difícil y muchas veces imposible para nosotros. Los hallazgos quirúrgicos —verdaderas sorpresas— se sucedían inexorablemente. Esta serie de fracasos diagnósticos nos llevó a pensar más en esta entidad, obligándonos a un mejor análisis de las pacientes, especialmente aquellas jóvenes, estériles, con dolor pélvico y trastornos del ciclo, que presentaban además cérvix sano, anexos palpables o masas anexiales sin antecedentes de infección séptica o gonocóccica.

Has Glycaemic Control in Diabetes Mellitus Improved Since the Introduction of Point-of-Care Glycated Haemoglobin A1c?
Authors: Constance Adams , Frederick Raal
Published: July 2020

Background: The mortality rate from diabetes-related complications in Sub-Saharan Africa surpassed that of HIV/AIDS, tuberculosis and malaria combined. Point-of-care (POC) glycated haemoglobin (HbA1c) has been in routine use at a tertiary hospital's diabetic clinic in Johannesburg, South Africa. This study set out to determine if having a readily available result on the day of consultation has led to improved glycaemic control.

Objective: The aim of this study was to determine if an immediately available POC HbA1c would result in more patients achieving target HbA1c compared to previously used laboratory HbA1c.

Methods: A retrospective audit of 195 attendees of the diabetic clinic at a public academic hospital who had been attending before the advent of the POC HbA1c test was recruited. The laboratory HbA1c taken on average 5 years before was compared to the current POC HbA1c to determine if there was any improvement in glycaemic control.

Results: The mean HbA1c before the POC test was 8.8% (SD 1.9) and the current POC HbA1c was 8.9% (SD 1.94). There was no statistically significant improvement in glycaemic control.

Conclusion: The POC test for HbA1c at a tertiary hospital's diabetic clinic did not result in improved glycaemic control. This study has shown that the introduction of new technology alone may not result in better diabetic care. Comprehensive diabetic care is multifactorial and relies on the intensive efforts of a multidisciplinary team including physician and diabetic nurse educator with active patient participation to ensure optimal glycaemic control.
Upskill/Backfill Model of Career Pathways Advancement: The Nebraska Vocational Rehabilitation Approach
Authors: Moore Dennis , Haines Kelly , Drudik Janet , Arter Zachary , Foley Susan
Published: July 2020

Current trends in vocational rehabilitation (VR) increasingly value career pathways and career advancement as important components for success. Simultaneously, employers and businesses have great needs for retaining and advancing incumbent workers in order to better meet their workforce demands. This article describes the Career Pathways Advancement Project (CPAP), the first state VR agency use of the upskill/backfill model for advancing former clients in specific career clusters in Nebraska VR by providing them access to additional training, certification, or specialized skills necessary to advance within that career sector. The model also provides access to entry-level jobs in the same businesses for current VR clients by “backfilling” the vacated positions left by the worker who is advancing. The upskill/backfill model appears to be an effective means for advancing former VR clients in their careers and providing substantial gains in income and employer-provided benefits. The model may require additional modifications in order to better serve new clients with backfill positions that were created by those who successfully advanced. Policy considerations for embedding this model in VR are addressed in light of evolving workplace dynamics and employer needs.

Published: July 2020

A configuração das janelas pode influenciar na luminosidade do ambiente e na comunicação visual de pacientes com o meio exterior. Para o bom aproveitamento dos benefícios da janela em ambientes hospitalares é importante verificar a contribuição da altura do peitoril. Esta pesquisa investiga a influência do peitoril no desempenho luminoso e na visão de céu em enfermarias hospitalares na cidade de Maceió, Alagoas. O objeto empírico compreende seis enfermarias femininas com mesmo desenho de janelas, mas com posição vertical e orientação distintas. Foi feita uma análise comparativa entre duas posições verticais da janela: alta e baixa, por meio de simulação computacional usando o software TropLux. Os resultados mostram que nos espaços analisados há ocorrência de desconforto devido ao excesso de luz natural, especialmente de luz direta do céu e do sol, causando ofuscamento. A falta de protetores solares nas aberturas faz com que haja grande quantidade de luz dentro do ambiente hospitalar, que é menos expressiva nas enfermarias que têm janelas voltadas para o vazio interno da edificação.
As folhas de videiras das Evas da Ilha de Marajó e a (des)construção de narrativas arqueológicas
Authors: Silva Emerson  Nobre da
Published: July 2020

A teoria queer tem possibilitado uma auto-reflexão à Arqueologia sobre a maneira como constrói a sua definição sobre o “outro” do passado a partir do espelhamento de valores e conceitos hegêmonicos. Diante disto, interpretações cisheteronormativas sobre as sociedades pretéritas têm sido questionadas, visando construir maneiras alternativas de representar o passado, sobretudo, no que diz respeito a gênero e sexualidade. Interpretações arqueológicas têm sugerido, desde a segunda metade do século XIX, que as tangas de cerâmica da fase marajoara eram usadas exclusivamente por mulheres e isto tem sido reproduzido até os dias de hoje. Este artigo revisita, a partir da crítica da Arqueologia Queer, a bibliografia referente às tangas cerâmicas com o intuito de compreender como esta ideia foi formatada, visando também confrontar os dados contextuais disponíveis.
