Lead Toxicity-Mediated Growth and Metabolic Alterations at Early Seedling Stages of Maize (Zea mays L.)
No full textTo investigate the toxic effects of lead (Pb) on key metabolic activities essential for proper germination and seedling growth of maize seeds, experiments were carried out with different levels of Pb (0 to 120 mg of Pb L−1 as PbCl2) applied through growth medium to two maize hybrids H-3310S and H-6724. The research findings indicated that growth and metabolic activities were adversely affected by increased Pb contamination in growth medium; however, a slow increase in these parameters was recorded with increasing time from 0 to 120 h. Protease activity decreased with an increase in the level of Pb contamination but increased with time; consequently, a reduction in seed proteins and an increase in total free amino acids were observed with time. Similarly, α-amylase activity decreased with an increase in Pb concentration in growth medium while it increased with increasing time from 0 to 120 h; consequently, reducing and non-reducing sugars increased with time but decreased with exposure to lead. The roots of both maize hybrids had higher Pb contents than those of the shoot, which decreased the uptake of nitrogen, phosphorus, and potassium. All these nutrients are essential for optimal plant growth; therefore, the reduction in growth and biomass of maize seedlings could be due to Pb toxicity that altered metabolic processes, as sugar and amino acids are necessary for the synthesis of metabolic compounds, rapid cell division, and proper functioning of enzymes in the growing embryo, but all were dramatically reduced due to suppression of protease and α-amylase by toxicity of Pb. In general, hybrid H-3310S performed better in Pb-contaminated growth medium than H-6724
Vehicle make and model recognition using bag of expressions
No full textThis article belongs to the Section Intelligent SensorsVehicle make and model recognition (VMMR) is a key task for automated vehicular surveillance (AVS) and various intelligent transport system (ITS) applications. In this paper, we propose and study the suitability of the bag of expressions (BoE) approach for VMMR-based applications. The method includes neighborhood information in addition to visual words. BoE improves the existing power of a bag of words (BOW) approach, including occlusion handling, scale invariance and view independence. The proposed approach extracts features using a combination of different keypoint detectors and a Histogram of Oriented Gradients (HOG) descriptor. An optimized dictionary of expressions is formed using visual words acquired through k-means clustering. The histogram of expressions is created by computing the occurrences of each expression in the image. For classification, multiclass linear support vector machines (SVM) are trained over the BoE-based features representation. The approach has been evaluated by applying cross-validation tests on the publicly available National Taiwan Ocean University-Make and Model Recognition (NTOU-MMR) dataset, and experimental results show that it outperforms recent approaches for VMMR. With multiclass linear SVM classification, promising average accuracy and processing speed are obtained using a combination of keypoint detectors with HOG-based BoE description, making it applicable to real-time VMMR systems.Muhammad Haroon Yousaf received funding from the Higher Education Commission, Pakistan

Does Knowledge Management Influence the Customer's Satisfaction and Intention to Quit? Mediating Role of Customer Relationship Management
No full textInternational audienceSatisfied customers are worthy assets for any organization. This study helps in understanding how important is to retain and enlarge these assets by minimizing the intention to quit and maximizing the satisfaction of customers. This research explores the importance of knowledge management and customer relationship management in order to retain advantageous and long-term bonds with customers in hotel industry. The purpose of this study is to examine the effect of knowledge management on customers' satisfaction and intention to quit by concentrating on the mediating role of customer relationship management. Data were collected by applying simple random sampling from employees and customers of hotels in Gujranwala. Results indicated that knowledge management has significant and positive relationships with customers' satisfaction. Moreover, knowledge management is negatively and significantly related to intention to quit. Additionally, customer relationship management also significantly mediates the relationship between knowledge management and customers' satisfaction & intention to quit
Structure of anisotropic fuzzy dark matter black holes
No full textBuilding on the Einasto dark matter (DM) density parameterizations, this study explores the possibility of constructing DM black holes (BHs) within the formalism of the Starobinsky gravity model. This approach extends the solutions characterizing the non-commutative mini BHs and introduces DM as the fundamental material constituting the BH. Assuming an anisotropic fluid configuration, we demonstrate the existence of different BH models subject to the values of the Einasto index and rescaled mass . To achieve this, we begin by considering a de Sitter-like equation of state (EOS) wherein . Interestingly, the resulting BH solution not only shares a similar horizon structure with a Reissner-Nordström BH but also replaces the central singularity with a regular de Sitter core through the mechanism of quadratic corrections. We further explore the possibility of using a nonlocal EOS instead of the previous one. This alternative approach allows us to construct a fuzzy DM stellar droplet. However, the radial pressure remains negative in this case. More precisely, we explore the possibility of these findings informing the existence of moderately massive DM-BHs within the galactic structures. Such objects could have played a role in the early stages of galactic formation. Furthermore, we delve into the intriguing possibility of these moderately massive DM-BHs acting as the central objects within galaxies
Exploiting the Reconfigurability of ρ-VEX Processor for Real-Time Robotic Applications
No full textAutonomous mobile robots generally have limited computational power on-board, and they have to perform their tasks in real-time in order to interact with their surroundings effectively. Therefore, there is a need to utilize the available computational capabilities efficiently. The ρ-VEX is a run-time reconfigurable VLIW processor. This unique processor allows separation of its issue lanes to form independently operating processing cores. Switching between these configurations during run-time allows optimizing the computing resources for the task(s) it is performing. In this project FreeRTOS is ported to the ρ-VEX processor and a control layer is developed. FreeRTOS manages the applications based on given real time parameters. The control layer decides the number of active cores (hardware contexts) and issue width of each core to best match the processing requirements of the applications. In this way, FreeRTOS and the control layer together can reconfigure the number of active cores at run-time. This is a very unique feature of this thesis project and can not be found in any other multicore implementation of FreeRTOS. The control layer along with FreeRTOS provides the user a facility to run applications under real-time constraints and with the best possible efficiency. In order to evaluate the performance, the overhead of the FreeRTOS is quantified and a performance comparison is made between several configurations of this system. Moreover, impact of reconfigurability of the ρ-VEX on the schedulability of real-time applications is measured and it is concluded that (indeed) reconfigurability of ρ-VEX improves the schedulability of the real-time applicationsElectrical Engineering, Mathematics and Computer ScienceComputer Engineerin
Examining Slavery\u27s Architectural Finishes: The Importance of Interdisciplinary Investigations of Humble Spaces
No full textThis thesis studies the evidence of architectural finishes in slave dwellings as a vehicle for understanding their lives, experiences and culture. Reviewing the finishes analyses of slave quarters in eight case studies, the author examines evidence of original finishes and observes how they can inform our understanding of slavery, including the possibility of a transfer of color traditions from Africa. The author also considers architectural and archaeological investigations performed on slave dwellings as a supplement to understanding these spaces and the use of African culture as a form of cultural resistance. The limited but important evidence underlines the need for additional research on the experience of slave life as drawn from material evidence
Political distinction in the British anti-capitalist movement
No full textThis article argues that Bourdieu's theory of practice provides a useful and dynamic framework which may be used to examine the reproduction of political practice. I use the Bourdieusian theoretical model to analyse and interpret data collected from 30 semi-structured interviews with British anti-capitalist activists from a range of anarchist and socialist political organizations and networks. The interviews reveal a clear case of political distinction between anarchists and socialists. The political history, political methods, and ideology of the activists become embodied and routinized over time. This explains why and how there is a durable ideological division which is consistently reproduced over and over again within sections of the British anti-capitalist movement. © The Author(s) 2011
