    AbstractStrong growth in the demand for tea requires further increases in the productivity of plantations. Declining or stagnant yields are commonly observed in older plantations. Possible controlling factors for yield decline are reviewed including ageing of plants, chronic disease and sub‐optimal soil conditions such as excess soil acidity and low soil organic matter. Management options for addressing these factors are evaluated, including replanting. A systematic approach to decision‐making about replanting is presented. Practice for replanting is reviewed and it is concluded that evidence to support a general case for replanting is limited, unless based on the introduction of more productive clones and/or better plant spacing. © 2013 Society of Chemical Industry

    Este artigo examina a distribuição espacial e a dinâmica da produção agropecuária da região do MATOPIBA, Brasil, usando técnicas de natureza visual e quantitativa. Utilizou-se a análise de redes, para modelar a estrutura produtiva da região, para anos selecionados do período de 1990 a 2012, e o conceito matemático de distância para medir a intensidade das mudanças interanuais. Consideraram-se 65 produtos cuja produção está estabelecida em ao menos uma das 31 microrregiões componentes. Os resultados indicam a coexistência de distintos perfis produtivos na região que foram se diferenciando ao longo do período analisado, embora tenha persistido um núcleo relativamente estável de microrregiões que compartilham a produção de itens dos domínios da pecuária e dos produtos da pecuária. Esses resultados mostram, também, o uso da modelagem com redes como técnica analítica válida nos estudos regionais sobre agricultura. Made available in DSpace on 2019-11-18T18:08:53Z (GMT).

    Studies on physiological and biochemical processes in crops are highly relevant for breeders to produce hybrids with high yield. Two different maturity groups of maize hybrids were tested in this study. The research site was located at the Látókép Experimental Station of the University of Debrecen and the experiment lasted for 2 years. The examined nitrogen ranges were separated into two parts. Firstly, the effects of nitrogen fertilizer ranging from 120–300 kg ha−1 were examined, supplemented with a constant, high-level P2O5 and K2O. Secondly, the optimal ratio of N:P:K was measured. In order to monitor the health status of maize hybrids, stress indicators including the activity of ascorbate peroxidase (APX), and superoxide dismutase (SOD), the rate of lipid peroxidation (LP), and grain yield were measured. The samples were taken in five phenological stages. Variance analysis based on nitrogen fertilizer showed variation in sampling times and fertilizers on APX, LP, and SOD. Variance analysis based on NPK indicated variation in sampling times, years, and fertilizer levels on APX, LP, and SOD. Correlation analysis showed that yield correlated negatively with SOD during the use of NPK fertilizer, as the use of nitrogen fertilizer cannot make corrections to yield with SOD but phosphorus and potassium can correlate with yield, and SOD. Principal component analysis showed that NPK5 and N5 had maximum stability and effect on yield. The activity of APX had the highest value during silking, and LP was in the V14 leaf stage. The correlation and principal component analysis showed that silking and the V14 leaf stage are the most important stages for yield, thus, higher attention must be paid to these stages in the LP and the activation of APX to achieve maximum yield.

    Internet of Things (IoT) environments are widely employed in industrial applications including intelligent transportation systems, healthcare systems, and building energy management systems. For such environments of highly sensitive data, adapting scalable and flexible communication with efficient security is vital. Research investigated wireless Ad-hoc/mesh networking, while Attribute Based Encryption (ABE) schemes have been highly recommended for IoT. However, a combined implementation of both mesh networking and Key-Policy Attribute Based Encryption (KPABE) on resource-constrained devices has been rarely addressed. Hence, in this work, an integrated system that deploys a lightweight KPABE security built on wireless mesh networking is proposed. Implementation results show that the proposed system ensures flexibility and scalability of self-forming and cooperative mesh networking in addition to a fine-grained security access structure for IoT nodes. Moreover, the work introduces a case study of an enabled scenario at a school building for optimizing energy efficiency, in which the proposed integrated system architecture is deployed on IoT sensing and actuating devices. Therefore, the encryption attributes and access policy are well-defined, and can be adopted in relevant IoT applications. 2013 IEEE.

    The development of IoT-based innovative learning media to improve student competence is needed in the era of industrial revolution 4.0. This study aims to develop an electrical practicum e-module using the Arduino Uno experimental tool to get valid, practical, and effective criteria. The research method uses R&D with four D models. The development stage consists of the stages of defining, designing, developing, and limited dissemination. Data analysis used descriptive analysis with Aiken V. The results showed that the e-module get the criteria of high validity with index V = 0.87. 60% of the total number of students responded positively to the media, and 40% were very active when using the media, so the modules developed were considered practical. The effectiveness level of the module shows that 100% of the students get a higher learning outcome value than the learning completeness score, so it can be concluded that the e-module has met the effective criteria.

    Abstract This paper is the first comprehensive report about the renewable fuels produced from the pyrolytic conversion of anaerobic and aerobic Brazilian high-ash sewage sludges. The study was divided into three steps: (1) an in-deep evaluation of physicochemical characteristics of both sewage sludges; (2) thermogravimetric analysis under inert conditions for determining bench-scale pyrolysis conditions; (3) characterization of volatile pyrolytic products from fixed bed reactor using GC/MS analysis. The anaerobic and aerobic sewage sludges present substantial high heating values and high contents of ash and sulfur, which are adverse properties for solid fuels. Regarding the pyrolytic behavior, the sewage sludge samples presented a two-step thermal decomposition process. The bio-oil produced from pyrolysis indicates that the high-ash sewage sludges are a source of high value-added chemicals, such as aliphatic and monoaromatic hydrocarbons. In addition, the pyrolysis can promote the production of a hydrogen-rich syngas for thermal boilers or engines use. In this research, it was demonstrated that the pyrolysis process of Brazilian high-ash sewage sludge can be applied for the production of useful biofuels - as bio-oil and bio-syngas - also adding value to this waste, thus contributing to the establishment of renewable source of bioenergy.

    Acoustic seafloor classification with multibeam backscatter measurements is an attractive approach for mapping seafloor properties over a large area. However, artifacts in the multibeam backscatter measurements prevent accurate characterization of the seafloor. In particular, the backscatter level is extremely strong and highly variable in the near-nadir region due to the specular echo phenomenon. Consequently, striped artifacts emerge in the backscatter image, which can degrade the classification accuracy. This study focuses on the striped artifacts in multibeam backscatter images. To this end, a calibration algorithm based on equal mean-variance fitting is developed. By fitting the local shape of the angular response curve, the striped artifacts are compressed and moved according to the relations between the mean and variance in the near-nadir and off-nadir region. The algorithm utilized the measured data of near-nadir region and retained the basic shape of the response curve. The experimental results verify the high performance of the proposed method.

    Land surface temperature (LST) is a key parameter in the processes of energy and water exchange between land and atmosphere. However, the MODIS LST products are often obscured by clouds and other atmospheric disturbances, resulting in severe data loss. Traditional interpolation methods cannot be effectively applied when there is large area of missing data. Thus, in this study, an effective LST interpolation method is developed to address this issue and is used to interpolate MODIS/Terra LST data on the Qinghai–Tibet Plateau in 2005. This method assumes that some pixels with spatially valid LSTs may follow a change trend over time similar to the null pixels, and the focus thus becomes to locate those similar pixels to interpolate each null pixel. First, LST images with a small amount of missing data, chosen as the reference images, were interpolated using a traditional interpolation method. Then, for each null pixel, other pixels with similar temporal changes of LST were identified by a similarity function. Finally, a transfer function for each null pixel was established based on those pixels most similar to it in the interpolated image and the corresponding reference image. The results were found to be much superior to those interpolated by traditional methods, such as regression Kriging, ordinary Kriging, and IDW. A specially designed experiment on an area that had ample valid LSTs confirmed that the proposed method can produce more favorable results than the other methods, and performed especially well when there was a significant lack of data.

    mean age, 15.7 years). Functional ambulation was assessed using the 10-Meter Walk Test and gait analysis in the sagittal plane before and after a single 20-min HAL intervention session. Results: The walking speed and stride length significantly increased after HAL intervention compared to the pre-intervention values. Two-dimensional gait analysis showed improvement in equinus gait, increase in the flexion angle of the swing phase in the knee and hip joints, and improvement in gait symmetry. Immediate improvements in the walking ability and gait pattern were noted after HAL training in patients with spastic CP. Conclusions: The symmetry of the joint angle of the lower limb, including the trunk, accounts for the improvement in walking ability after HAL therapy. (HAL) has been effective in improving walking ability in patients with CP. However, previous studies have not examined in detail the changes in gait pattern after HAL training for patients with spastic CP, including gait symmetry. This study aimed to evaluate the immediate effect of HAL training on the walking ability and the changes in gait pattern and gait symmetry in patients with spastic CP. Materials and Methods: We recruited 19 patients with spastic CP (13 male and six female Background and objectives: Cerebral palsy (CP) is the most frequent childhood motor disability. Achieving ambulation or standing in children with CP has been a major goal of physical therapy. Recently, robot-assisted gait training using the Hybrid Assistive Limb®

    AbstractStrong growth in the demand for tea requires further increases in the productivity of plantations. Declining or stagnant yields are commonly observed in older plantations. Possible controlling factors for yield decline are reviewed including ageing of plants, chronic disease and sub‐optimal soil conditions such as excess soil acidity and low soil organic matter. Management options for addressing these factors are evaluated, including replanting. A systematic approach to decision‐making about replanting is presented. Practice for replanting is reviewed and it is concluded that evidence to support a general case for replanting is limited, unless based on the introduction of more productive clones and/or better plant spacing. © 2013 Society of Chemical Industry

    Este artigo examina a distribuição espacial e a dinâmica da produção agropecuária da região do MATOPIBA, Brasil, usando técnicas de natureza visual e quantitativa. Utilizou-se a análise de redes, para modelar a estrutura produtiva da região, para anos selecionados do período de 1990 a 2012, e o conceito matemático de distância para medir a intensidade das mudanças interanuais. Consideraram-se 65 produtos cuja produção está estabelecida em ao menos uma das 31 microrregiões componentes. Os resultados indicam a coexistência de distintos perfis produtivos na região que foram se diferenciando ao longo do período analisado, embora tenha persistido um núcleo relativamente estável de microrregiões que compartilham a produção de itens dos domínios da pecuária e dos produtos da pecuária. Esses resultados mostram, também, o uso da modelagem com redes como técnica analítica válida nos estudos regionais sobre agricultura. Made available in DSpace on 2019-11-18T18:08:53Z (GMT).

    Studies on physiological and biochemical processes in crops are highly relevant for breeders to produce hybrids with high yield. Two different maturity groups of maize hybrids were tested in this study. The research site was located at the Látókép Experimental Station of the University of Debrecen and the experiment lasted for 2 years. The examined nitrogen ranges were separated into two parts. Firstly, the effects of nitrogen fertilizer ranging from 120–300 kg ha−1 were examined, supplemented with a constant, high-level P2O5 and K2O. Secondly, the optimal ratio of N:P:K was measured. In order to monitor the health status of maize hybrids, stress indicators including the activity of ascorbate peroxidase (APX), and superoxide dismutase (SOD), the rate of lipid peroxidation (LP), and grain yield were measured. The samples were taken in five phenological stages. Variance analysis based on nitrogen fertilizer showed variation in sampling times and fertilizers on APX, LP, and SOD. Variance analysis based on NPK indicated variation in sampling times, years, and fertilizer levels on APX, LP, and SOD. Correlation analysis showed that yield correlated negatively with SOD during the use of NPK fertilizer, as the use of nitrogen fertilizer cannot make corrections to yield with SOD but phosphorus and potassium can correlate with yield, and SOD. Principal component analysis showed that NPK5 and N5 had maximum stability and effect on yield. The activity of APX had the highest value during silking, and LP was in the V14 leaf stage. The correlation and principal component analysis showed that silking and the V14 leaf stage are the most important stages for yield, thus, higher attention must be paid to these stages in the LP and the activation of APX to achieve maximum yield.

    Internet of Things (IoT) environments are widely employed in industrial applications including intelligent transportation systems, healthcare systems, and building energy management systems. For such environments of highly sensitive data, adapting scalable and flexible communication with efficient security is vital. Research investigated wireless Ad-hoc/mesh networking, while Attribute Based Encryption (ABE) schemes have been highly recommended for IoT. However, a combined implementation of both mesh networking and Key-Policy Attribute Based Encryption (KPABE) on resource-constrained devices has been rarely addressed. Hence, in this work, an integrated system that deploys a lightweight KPABE security built on wireless mesh networking is proposed. Implementation results show that the proposed system ensures flexibility and scalability of self-forming and cooperative mesh networking in addition to a fine-grained security access structure for IoT nodes. Moreover, the work introduces a case study of an enabled scenario at a school building for optimizing energy efficiency, in which the proposed integrated system architecture is deployed on IoT sensing and actuating devices. Therefore, the encryption attributes and access policy are well-defined, and can be adopted in relevant IoT applications. 2013 IEEE.

    The development of IoT-based innovative learning media to improve student competence is needed in the era of industrial revolution 4.0. This study aims to develop an electrical practicum e-module using the Arduino Uno experimental tool to get valid, practical, and effective criteria. The research method uses R&D with four D models. The development stage consists of the stages of defining, designing, developing, and limited dissemination. Data analysis used descriptive analysis with Aiken V. The results showed that the e-module get the criteria of high validity with index V = 0.87. 60% of the total number of students responded positively to the media, and 40% were very active when using the media, so the modules developed were considered practical. The effectiveness level of the module shows that 100% of the students get a higher learning outcome value than the learning completeness score, so it can be concluded that the e-module has met the effective criteria.
