Response of Onion Plants to Organic Fertilizer and Foliar Spraying of Some Micronutrients Under Sandy Soil Conditions

Aiming to study the effect of organic fertilizer (compost at rates of 5.0 and 7.5 tons/fed.) and foliar application of micro-nutrients Fe, Zn or Mn at a dose of 2 cm/l for three times in 15 days interval as well as control treatment (no compost added and no micro-nutrients sprayed), on growth characters, bulb yield and its components as well as some physical properties of bulb of onion plants cv. Giza 20 grown under sandy soil conditions, two experiments were carried out at Agricultural Experiment Station of National Research Centre, in a split plot design with three replicates during two consecutive winter cropping seasons of 2011/2012 and 2012/2013. Application of Nile compost either at 5.0 and 7.5 tons/fed. caused an enhancement in all measured parameters as compared to control treatment. Onion plants treated with Nile compost at rate of 7.5 tons/fed. gave the highest values of plant length, number of leaves/plant, fresh and dry weight of whole plant and its different organs, bulb and neck dimensions, average weight of bulb, bulb TSS, total bulb yield, percentage of yield increase over control and exportable yield in comparison to control treatment in both season of study. Whereas, using Nile compost at rate of 5.0 tons/fed. attained the highest values of un-marketable and percentage of un-marketable bulb yield in the second season as well as percentage of exportable bulb yield in both seasons. Foliar application of micro-nutrients had a stimulating effect on all measured characters if compared with control treatment. Control treatment recorded the highest values of local marketable and percentage of local marketable bulb yield in both seasons as well as un-marketable and percentage of un-marketable bulb yield in the first season only. The highest values of the rest characters were fluctuated among sprayed micro-nutrients Fe, Zn or Mn without significant differences among them, significant differences were detected only between control treatment and micro-nutrients spraying in both seasons. Regarding, the interaction effect between Nile compost and foliar application of some micro-nutrients, had significant differences only on total bulb yield and un-marketable bulb yield in both seasons of study. Furthermore, on bulb and total plant fresh weight, exportable bulb yield, neck length and bulb diameter in the first season and on plant length, neck dry weight and local marketable bulb yield in the second season. It is evident that onion plants gave the best results in both seasons when Nile compost was used at a rate of 7.5 tons/fed. and foliar sprayed by Zn or Mn.
Concentric tube heat exchanger installed by twisted tapes using various wings with alternate axes

The effects of twisted tapes using various wings with alternate axes on heat transfer, flow friction and thermal performance characteristics in a concentric tube heat exchanger are experimentally investigated. The influence of wing shape including triangle, rectangle and trapezoid are also studied. The experiments are performed using twisted tape with the constant wing-chord ratio (d/W) of 0.31, constant wing-span ratio (b/W) of 0.23 and constant twist ratio (y/W) of 3.8, over a Reynolds number range of 5800–18,500. The alternate axes are made by arranging each plane of twisted tape to 60-degree difference about the adjacent plane. The tests using the plain tube and tube with typical twisted tape were also conducted for a comparison. The results show that both heat transfer rate and friction factor associated with all twisted tape are consistently higher than those without twisted tape. Under the similar operating conditions, Nusselt number, friction factor as well as thermal performance factor given by t.
Analyzing the Optimal Reactive Power Dispatch in the Presence of Series and Shunt Facts Controllers

The reactive power dispatch is one of the generalized optimal power flow (OPF) problems to dispatch reactive power optimally to maintain the voltage magnitude at the load buses. The OPF problem with total power loss as an objective is solved while satisfying system equality and in-equality constraints. It is necessary to solve the optimal power flow in the presence of series and shunt flexible AC transmission system controllers such as thyristor controlled series capacitor and static VAr compensators. The optimal location of these controllers is identified so as to maximize the system security. The optimal parameters of this controller and system are identified using the developed gravitational search algorithm. The effectiveness of the proposed methodology with TCSC and SVC is tested on standard IEEE-30 bus test system with supporting numerical and as well as graphical results.
Choosing between modern and heritage buildings for professional services

The role of building facades in the consumer choice process is not well understood but arguably influences consumers' first impressions of a business and the level of service provided by the professional working within. In two studies, photographs representing exteriors of two building types (purpose-built office and converted heritage house) were shown to participants who chose between them for hypothetical dental, legal, financial, and medical services and assessed them for expected comfort and quality of service. In Study 1, students preferred office buildings for all services. In Study 2, community residents also preferred office buildings for dental, financial, and medical services but not for legal services. In both studies, participants had more experience with office buildings compared to heritage houses for all four services and anticipated more comfort and service quality in offices, especially for dental, financial, and medical services compared legal services. However, more comfort was expected by those in Study 2 when considering legal services over the other three services in heritage houses. Although office buildings are commonly experienced and preferred as settings of professional practice, heritage houses can be legible as places to access comfortable, quality service.
Changes in synoptic weather patterns in the polar regions in the twentieth and twenty‐first centuries, part 1: Arctic

An analysis of late twentieth and twenty‐first century predictions of Arctic circulation patterns in a ten‐model ensemble of global climate system models, using the method of self‐organizing maps (SOMs), is presented. The model simulations were conducted in support of the fourth assessment report of the intergovernmental panel on climate change (IPCC). The analysis demonstrates the utility of SOMs for climate analysis, both as a tool to evaluate the accuracy of climate model predictions, and to provide a useful alternative view of future climate change.

Considerable Size Reduction of Dipole Antenna with a Compact and Broadband Balun

A compact and broadband balun is designed using a conventional right-handed transmission line (RHTL) and a left-handed transmission line (LHTL) with lumped elements only. The proposed balun maintains a phase difference of 180° ± 12° at the output ports for the frequency range of 1.27 GHz-2.69 GHz. Nevertheless, the circuit size is merely 9.5 mm × 12.7 mm. To verify the performance of the proposed balun, we attached it to a dipole-type antenna and observed that the return loss is greater than 10 dB for the frequency range between 1.86 GHz and 2.57 GHz. The radiation pattern and peak gain are similar to those of the dipole antenna with a conventional balun.
An artificial bee colony algorithm with local search for vehicle routing problem with backhauls and time windows

This paper presents an artificial bee colony algorithm to solve the vehicle routing problem with backhauls and time windows (VRPBTW). This problem is a combination of the vehicle routing problem with backhauls (VRPB) and the vehicle routing problem with time windows (VRPTW). In VRPBTW, a homogenous fleet of vehicles are utilized to deliver goods to customers in linehaul set and then to pick up goods from customers in backhaul set. Vehicle capacity, backhaul and time windows are the major constraints for this problem. The objective of VRPBTW is to minimize the sum of route distance that satisfy all constraints. An artificial bee colony (ABC) algorithm with local search procedures are proposed to solve the modified Solomon’s VRPTW benchmark problems. The results of computational experiments reveal that the performance of the proposed ABC algorithm is comparable to the other metaheuristics in terms of the quality of solution.
Imprints of Ocean Chaotic Intrinsic Variability on Bottom Pressure and Implications for Data and Model Analyses

Variations in ocean bottom pressure are important for understanding ocean circulation and climate. While most studies have focused on atmospherically driven variability, here we use eddy‐permitting large ensemble simulation output from the OceaniC Chaos–ImPacts, strUcture, predicTability (OCCIPUT) project to isolate chaotic intrinsic variability generated by nonlinear oceanic processes. Analyzing separately the mean seasonal cycle and remainder variability in intra‐annual (60–365 days) and subseasonal (2–60 days) bands, we find intrinsic variations larger than atmospherically driven ones over eddy‐active regions across all timescales, particularly in the intra‐annual range, where intrinsic variations dominate in almost 25% of the oceans. At scales larger than mesoscale, intrinsic variability is still considerable, supporting the process of energy inverse cascade toward lower frequency and larger scales. Results highlight the importance of intrinsic variability over a range of spatiotemporal scales and provide new insights on the interpretation of GRACE‐like observations and their de‐aliasing procedures.
THE UTILIZATION OF SYSTEM USABILITY SCALE IN LEARNING MANAGEMENT SYSTEMS: A CASE STUDY OF JEDDAH COMMUNITY COLLEGE

Learning Management Systems (LMS) have been widely adopted in many higher educational institutions to support teaching and learning activities. The study was conducted with the aim of investigating the usability of the learning management system (Blackboard) at Jeddah Community College (JCC) from the students' perception, using a System Usability Scale (SUS) survey. The study examined the association between SUS scores and different variables: age, prior experience with LMS, ICT skills, attitude towards the Internet and LMS usage frequency. All participants were students at JCC. The online survey was sent by email to students who were enrolled in Information Technology (IT) courses during the 2016 summer semester. 50 responses were received and used for data analysis. The findings indicate that the overall mean of SUS score is 69.3 (SD 11.31), indicating that the current LMS has some usability issues. It was also found that the students’ LMS usage frequency is positively correlated with their SUS score. The findings can be used to consider the effectiveness of LMSs.
Community survey on noise impacts induced by 2 MW wind turbines in China

In order to investigate the noise impacts of wind turbines with a high single-machine capacity (2 MW) on the residents living around, a face-to-face questionnaire survey was conducted. The moderating factors of noise annoyance, noise exposure–response relationships as well as noise impacts on sleep and self-reported health were investigated. Results showed that noise sensitivity, attitude towards wind turbines’ visual impact on the landscape, general opinion on wind turbines and noise intensity had statistically significant impacts on annoyance due to wind turbine noise. Compared with wind turbines with lower single-machine capacity in relevant studies, those with higher single-machine capacity in this study induced higher annoyance at the same Lden, which was relative to the visibility of wind turbines, background noise levels of wind farm area, etc. Noise sensitivity, noise annoyance and noise intensity, which had no significant correlation with self-reported health effects, were statistically significantly correlated with sleep disturbance on respondents.
The synoptic climate controls on hydrology in the upper reaches of the Peace River Basin. Part I: snow accumulation

For most cold region rivers, winter snowpack accumulation is the main contributor to spring run‐off events. This study investigated the synoptic controls on snowpack variability in the upper reaches of the Peace River Basin. An examination of snowpack accumulation at Grande Prairie, Alberta, revealed considerable inter‐annual variability for the period 1963–1996. Moreover, a decadal‐scale shift was evident with the magnitude of the snowpack being significantly reduced after 1976.

Temperature, physiological time, and zinc toxicity in the isopod Porcellio scaber

Temperature is an important controlling factor in the metabolism of ectotherms, and it may interact with the toxicity of heavy metals in a variety of ways. In this work, a study on the effect of different zinc concentrations (0.3, 13, 26, and 40 μmol/g dry litter) on growth (body weight) of the isopod Porcellio scaber was conducted using four temperature levels (12, 16, 20, and 24°C). The results demonstrated a significant effect for both zinc and temperature on the growth rate; the interaction between zinc and temperature was also significant. The Arrhenius function was used to describe the temperature–growth rate relationship, from which estimates for the activation energy were derived. A tendency for activation energy to decrease with increasing zinc concentration was observed. Isopods exposed to 13 μmol Zn/g had the highest activation energy and the highest growth rate. To analyze the effect of temperature on the internal body concentration of zinc, the exposure time was transformed into physiological time, calibrated at 15°C, for all experimental groups using the activation energies estimated earlier. The rate of zinc accumulation was derived from the relationship between internal body concentration and physiological exposure time. Differences between isopods cultured at different temperatures could be explained well by the effect of physiological exposure time. The interaction between temperature and zinc toxicity seems to be due not to increased accumulation of zinc at higher temperatures as such but to a physiological interaction with the energy metabolism.

Complete protection scheme for fault detection, classification and location estimation in HVDC transmission lines using support vector machines

This paper presents a complete protection scheme for detecting, classifying and locating the fault in HVDC transmission lines using support vector machines (SVM). SVM has been used for protective relaying application in HVAC transmission line, however very limited works have been reported for HVDC transmission line. In this work, a ±500 kV HVDC transmission system is developed in PSCAD/EMTDC and the measurement signals obtained are analyzed in MATLAB. The rectifier side AC RMS voltage, DC voltage and current on both the poles are continuously monitored, and given as input to the SVM binary classifier in order to detect the presence of fault in the line. Once a fault is detected, the SVM multi-class classification module predicts the type of fault and the SVM regression algorithm predicts the location of fault. The feature vector used in the classification and location modules is the standard deviation of the signals over half cycle before and after the occurrence of fault. The method proposed is simple as it requires single-end data and a direct standard deviation of one cycle data gives very accurate results. The detection and classification modules are 100% accurate whereas the fault location module has a mean error of 0.03%.
Three Generations of Telework: New ICTs and the (R)evolution from Home Office to Virtual Office

‘New ICTs’, such as smartphones and tablet computers, have revolutionised work and life in the 21st Century. Crucial to this development is the detachment of work from traditional office spaces. Today's office work is often supported by Internet connections, and thus can be done from anywhere at any time. Research on detachment of work from the employer's premises actually dates back to the previous century. In the 1970s and 1980s, Jack Nilles and Allan Toffler predicted that work of the future would be relocated into or nearby employees’ homes with the help of technology, called ‘Telework’. Analysing technological advancements—the enabling forces of change in this context—over four decades sheds new light on this term: they have fostered the evolution of Telework in distinct stages or ‘generations’. Today's various location-independent, technology-enabled new ways of working are all part of the same revolution in the inter-relationship between paid work and personal life.
Experimentally Validated Nonlinear Analysis of Bridge Plate Girders with Deformations

Abstract Comprehensive methodology of numerical nonlinear analysis of the consecutive phases in the structural behaviour of bridge plate girders with deformations is presented. The analysis concerns all stages of structure loading until failure and especially determination of the ultimate shear load capacity. Verification and validation of the numerical procedures proposed is based on comparison of the calculated results with effects of experimental laboratory shear capacity tests of plate girders carried out at the University of Ljubljana.
A comparative study on the state-of-the-art prediction tools for seakeeping

An accurate prediction of the seakeeping behavior of ships is important for both their design and operation. The following issues play a role: Wave induced (relative) motions and accelerations should be minimized for the well-being of the crew and passengers1 and in the extreme; to minimize capsize risk and to avoid slamming. Internal loads should be kept at acceptable levels to ensure structural integrity during a ship's lifetime. o The added resistance in waves increases fuel consumption and should be minimized. The Cooperative Research Ships (CRS) is a group of companies with a common interest in research in ship hydrodynamics. The research tasks carried out are aimed at fundamental research and at design and operation. Together they decide which research topics are investigated and carry out the research. CRS now has 23 members, which include shipyards,ship owners, classification societies, navies, consulting finns and research institutes/model basins. CRS has 'been working since 1969. Within CRS a vast amount of research knowledge is being accumulated. Moreover, the international cooperation in executing the work strongly broadens the knowledge of the members. The CRS recognizes the importanceof improving the accuracy of seakeeping tools and sought means to make a step forward. The CRS therefore organized a workshop in which a number of research groups were invited to carry out seakeeping predictions for a number of ships. For these ships model tests have been carried out in the past and results are made available to workshop participants. The ultimate goal of the 28'' Symposium on Naval Hydrodynamics Pasadena, California, 12-17 September 2010 A comparative study on state-of-the-art prediction tools for seakeeping Tim Bunnik', Ed van Daalen', Geert Kapsenberg', Yung Shin2, Rene Huijsmans3, Ganbo Deng4, Gerard Delhomrneau4, Masashi Kashiwagi5, Bob Beck6 ('MARIN, 2ABS, 3DUT, 4ECN, Osaka University5, University of Michigan6) workshop was to select a method as a basis for the next generation CRS seakeeping tool . This method should have enough accuracy, robustness and computational efficiency. The research groups were selected such that they covered a range of different methods: Approximate Forward Speed (AFS): Linear potential method linearising around the undisturbed flow, applying zero-speed Green Functions. Exact forward speed (EFS): Linear potential method linearising around the undisturbed flow applying forward-speed Green Functions. Double Body (DB): Linear potential method linearising around the doub1ebody flow. Non Linear Steady (NLS): Linear potential methods linearising around the non-linear steady wave field. Computational Fluid Dynamics (CFD) The test cases that were selected include a container ship and a ferry, for which experimental data was available. The comparison focused on motions, relative motions, added resistance and internal loads.
