Effect of vermicompost on protein content of Soybean-Glycine max

The term weed is used generally to unprofitable, troublesome or noxious growth and unwante plants in human controlled settings especially farms, fields and water bodies. Mechanical removal and weedicidal spray are common methods to eradicate weeds, but both these methods are not feasible. The disposal and decomposition of weed biomass is also a big problem. The present study deals with the use of weed biomass for the vermicomposting. Vermicompost of three common weeds of this area Parthenium hysterophorous, Lantana camara and Eichhornia cresipes was prepared as proposed by the Rajkhowa, et . al.(2005). The prepared vermicompost of all the three weeds was used as biofertilizer in soybean crop separately. The protein content was assessed at the regular interval of 15 days till 75 days, in all the vermicompost treatments. The study revealed that in all the three vermicompost treated soil protein content increased considerably over control. This clearly indicates that weed biomass can be utilized for vermicomposting, and the prepared vermicompost is beneficial for growing of crops.
What Levels of Guidance Promote Engaged Exploration with Interactive Simulations

We became teachers because we want everyone to be able to see through science the elegance in nature as we do. Our instincts and training may lead us to “tell” students about science and math as we understand it. Unfortunately research has shown that simply telling is not always the most effective way to share our understanding. Simulations are a valuable instructional resource and can provide a wealth of data about student engagement and learning. Approximately 250 interviews have been conducted with simulations developed by the Physics Education Technology (PhET) Project. We’ve conducted interviews using several different levels of guidance and found that the nature of guidance influences the amount of student engagement. Minimal but nonzero guidance with many of these simulations promotes optimum engaged exploration and learning.

A Practical Guide to Feature-Driven Development

From the Publisher: Feature-Driven Development (FDD), created by Peter Coad (Chief Architect), Jeff De Luca (Project Manager), and Stephen Palmer (Development Manager), combines the key advantages of agile methodologies with model-driven techniques that scale to the largest teams and projects. This book demonstrates FDD at work in real-world projects and provides project leaders with all the information they need to successfully apply it in their own organizations. Stephen R. Palmer and John M. Felsing show how applying FDD can help solve problems that both traditional and modern software-development processes fail to address. They help you identify the projects that are best suited for FDD, and then walk you step by step through the entire FDD development process.
Rapid prototyping of green composites

Rapid prototyping employs digital fabrication techniques to quickly manufacture parts. However, the available materials are not yet suitable for making strong, large or durable objects. Composites are materials which are very strong and lightweight, combining the tensile strength of a fibre and the compressive strength of a resin matrix. Unfortunately, tooling for composite parts is currently expensive, slow to make, and therefore out of reach for many small-scale projects. Furthermore, popular composites are toxic to the environment and the people who work with them. Green-, ecoor biocomposites employ natural fibres in conjunction with biodegradable, renewably sourced or less toxic (in use and in manufacturing) matrices. Benefits of using natural fibre composites are that besides being light, strong and less toxic, they are also cheaper, of lower density, easier to work with and more environmentally friendly than carbon– or glass-fibre composites. The latest techniques and efforts on green composites however remain firmly in the lab– the resources evaluated are not readily accessible for manufacturing in the field. Local specialised projects now can use digital fabrication tools to realise structures previously considered prohibitively expensive to manufacture without an economy of scale. But because of the cost, difficulty and potential health hazards of composites, they have not yet been explored as a material for small scale local manufacturing. Digitally fabricated tooling introduces composite manufacturing as a rapid prototyping method. Green composites enable worker-safe manufacturing with environmentally friendly materials. Together, digitally fabricated tooling and green composite workflows allow faster, cheaper, stronger and less toxic large-scale prototyping in the field. I present an evaluation of green(er) composite materials which can be sourced and made in the field using low-cost digitally fabricated tooling. This includes case studies in medical devices, vehicles and housing. Thesis supervisor: Dr. Neil Gershenfeld Professor of Media Arts and Sciences Program in Media Arts and Sciences
PET is only moderately informative regarding theranostic Ttarget HIF-1α expression in solid tumors: A meta-analysis

BACKGROUND: Hypoxia-inducible factor (HIF)-1α plays a key role in hypoxic adaptation of tumor cells. HIF-1α is overexpressed in solid tumor, directs the glucose metabolism pathway from oxidative to anaerobic pathway thereby reducing the oxygen consumption, decreases free radical level and thence prevents cancer cell death. 2-deoxy-2 [18F] fluoro-D-glucose (FDG) is taken up in solid tumors primarily regulated through glucose transporter 1 (GLUT-1) and hexokinase 2 which in turn are regulated by HIF-1α. Positron Emission Tomography (PET) with FDG allows semiquantitative delineation of GLUT-1 and Hexokinase 2 activity in tumor cells by standardized uptake value (SUV). There are inconsistent data about relationships between FDG-PET and HIF-1a. The purpose of the present analysis was to provide evidence regarding associations between FDG uptake measured as standardized uptake value (SUV) and HIF-1α expression in solid tumors. METHODS: MEDLINE library, SCOPUS and EMBASE data bases were screened for relationships between SUVmax and HIF-1a up to August 2019. Overall, 21 studies with 1154 patients were identified. The following data were extracted from the literature: authors, year of publication, number of patients, and correlation coefficients. RESULTS: Correlation coefficients between SUV and HIF-1α ranged from -0.51 to 0.71. The pooled correlation coefficient was 0.27, (95% CI = [0.14; 0.41]). Furthermore, correlation coefficients for specific tumor entities were calculated. For this sub-analysis, data for primary tumors with more than two reports were included. The calculated correlation coefficients in the analyzed subgroups were as follows: head and neck squamous cell carcinoma: ρ = 0.25 (95% CI = [0.07; 0.42]); non-small lung cell cancer: ρ = 0.27 (95% CI = [-0.14; 0.67]); uterine cervical cancer: ρ = -0.09 (95% CI = [- 0.89; 0.71]); thymic tumors: ρ = 0.39 (95% CI = [0.04; 0.58]) CONCLUSION: Published literature suggests wide heterogeneity and weak correlation between intensity of FDG uptake measured as SUVmax and expression of HIF-1a both in solid tumors in general and also in specific tumor subgroups. Because HIF-1α is a very important theranostic target, prospective state of the art studies are needed to elucidate the true potential of FDG PET in assessment of HIF-1α activity in solid tumors
Exploring Factors Influencing Resilience Among Flood Victims in Malaysia

In December 2014, Malaysia was shocked by the massive floods that affect physical destruction and also leaving flood victims with psychological problems. Based on previous research, resiliency is an element that can protect the flood victims from experiencing severe psychological issues. Therefore, the objective of this study was to explore the factors influencing resiliency among flood victims in Kelantan, Malaysia. To carry out this study, a qualitative approach using case study as a research design was employed. A total of 28 flood victims were selected for in-depth interview sessions. Respondents were selected by using purposive sampling. The data were collected and analysed using thematic analysis. The findings reported that there were four factors that influenced respondents’ resiliency, which emerged as themes namely self-efficiency, coping strategies, characteristics of community spirit and social support. The finding would provide information for relevant intervention programme which will lead to improve the physical and psychological well-being of flood victims in Malaysia.
Spectrum–Conservation Techniques for Fixed Microwave Systems

Since the spectrum is a limited natural resource, the spectrum management community has a major interest in identifying spectrum conservation techniques that will provide more efficient spectrum utilization. Advances in new technology for fixed microwave systems in antennas, modulation schemes and signal processing techniques offer increased efficiency in spectrum utilization. This report analyzes the spectrum conserving properties of the various new technologies for fixed microwave systems applying the concepts in CCIR Report 662–2, and was defined as the spectrum conservation factor (SCF). The report concludes that the SCF technique is an effective indicator of the spectrum conserving properties of technologies which can be used to develop new spectrum standards.
Analyse et mise en oeuvre d"un moteur électromagnétique microfabriqué

Until now, the preferred solution for MEMS (Micro Electro Mechanical Systems) actuation is the electrostatic one. The main reason is that this kind of actuators can be easily manufactured following the microfabrication rules, as their geometry perfectly fits to the characteristics of this technology. On the other hand, electromagnetic systems are rarely developed at small scale. Two explanations can be given. First, ferromagnetic materials are not available in standard cleanroom processes and secondly, adapting the typical three-dimensional geometry of electromagnetic drives to a planar technology is quite difficult. This thesis addresses the design of a new electromagnetic MEMS micromotor. The aim is to develop a new motor, which is able to satisfy the specifications of the watchmaker industry. The state of the art and the scaling laws show that a permanent magnet is compulsory to obtain small scale high performances motors. This is one of the reasons why, according to the project specifications, a permanent magnet synchronous motor (BLDC) seems to be the best solution. The designed motor is hybrid because it combines a microfabricated stator and a common magnet obtained with standard macroscopic fabrication processes. Its geometry is characterized by the overlapping of the rotor over the stator and it is well suited to the microsystems manufacturing principle which is based on the design of stacked layers. In order to design the motor, an analytical electromagnetic model has been developed. The accuracy of this mathematical model has been validated by means of finite elements simulations before using it to find the optimal design. Optimization results are very interesting and they demonstrate the suitability of such electromagnetic micromotor for the watch industry. At least, the same performances as the Lavet motor, which actually drives the clock hands, are predicted. Prototypes manufacturing is indispensible for theoretical analysis validation. Moreover, for the current project, this part has a higher importance because the feasibility of the stator microfabrication must also be demonstrated. These components are made following a process flow that has been especially developed for this application by combining several methods available in cleanrooms. It allows carrying out coils with two copper layers. Even if it seems to be complicated and with many steps, a great effort has been made to obtain the simplest and most reliable process flow. Prototypes have been assembled using standard watchmakers bearings. The goals are to validate the theoretical results and to highlight the critical fabrication steps as well as secondary phenomena, which were not considered during the design phase. Once again, the motors characterization demonstrates the great potential of electromagnetic MEMS.
Willingness-to-Pay for Public Eco-tourism Services in Malaysia

The main focus of this study is to determine the attributes of willingness-to-pay (WTP) of the general public towards the entrance fee for using services in the Public Ecotourism Organization. Contingent Valuation Method is used to estimate the value of non-market good by adopting WTP approach. WTP is the maximum amount consumers are prepared to pay for a good or service and to enjoy recreational facilities. It measures whether an individual is willing to forego their income in order to obtain more goods and better services, and WTP is typically used for non-market goods. This study adopted questionnaires survey to examine the perception on the willingness to pay by visitors for the fees charged by the authorities for the services they provided. 100 local and international respondents among visitors involved in the study. The findings showed that National Park can give a new experience to visitors with beautiful natural landscape. However, the respondents perceived that road linkages of National Park are not proper and fee charged for boat services a bit too high. While, National Zoo is visited mostly to spend time and holiday with family due to attractive wildlife shows available daily. The authority however, needs to improve on hygienic aspect and perhaps to lower down the entrance fees. The attractiveness and shortcoming of the National Park and National Zoo are identified in order to suggest for improvements of services to public. As the economic growth, people will demand for better services and facilities or else willingness to pay will be affected. Thus, it is important for the government organizations to upgrade their services and facilities over time to fulfill the needs of the people.

Comparison of Dual-Phase and Static Changeable Message Signs to Convey Airline Information on Interstate Freeways

The authors used a fully interactive PC-based STISIM driving simulator to compare dual-phase Changeable Message Signs (CMSs) and static CMSs. The participants were 120 licensed drivers from three age groups: 18-24, 32-47, and 55-65 years of age. They drove eleven miles on a simulated six-lane highway towards an airport, knowing which airline to look for. Airline information was provided on two separate CMSs located 500 ft (152.4 m) apart on the highway in one condition, or on a single dual-phase CMS in the other condition. The participants took the correct exit on 89.6% of the drives (215 of 240). There were no statistically significant differences between the number of participants who failed to take the correct exit in the dual-phase and the static CMS conditions. On the approach to the CMSs displaying airline information, there were significant differences in average speed between the three age groups—younger drivers drove faster than middle age and older drivers. However, average speeds were not different in the dual-phase and static CMS conditions. Some individuals reduced speed on approaching the CMSs—suggesting similar reductions could occur in real world driving in free flow conditions. There were no differences in the number or magnitude of the speed reductions for the dual-phase and static CMS conditions. In this experiment, displaying airline information on a single dual-phase CMS was as effective in influencing driving behavior as displaying the same airline information on two static CMSs.
Economic Uncertainty and Remittances Flow: Heterogeneity Matters

The recent Global Financial Crisis has threatened global economic and financial stability and as a consequence, reinforced our interest in examining the impact of economic uncertainty. Given the growing importance of remittances to the growth and development of economies, this paper examines how economic uncertainty shocks impact inward remittances of a panel of 53 developing and least developed countries over the period 1996-2018. Using a two-step system GMM approach, we find that economic uncertainty shocks induced a positive and statistically significant remittance response to developing and least-developed economies. The result is consistent with the predominant altruistic behavior of migrants from developing economies, and further, suggests the importance of migrants’ remittances in moderating the potential adverse effects of uncertainty.
Haptic Interface for UAV Teleoperation

In the teleoperation of an uninhabited aerial vehicle (UAV), the human operator is physically separated from the vehicle and lacks various multiple-sensory information such as sound, motions, and vibrations of the airframe. The operator is usually only provided with visual information, e.g., from camera images with limited resolution and field of view. All this leads to lower situation awareness, which in turn leads to reduced safety in teleoperation and high operator workload. The goal of this thesis is to increase the safety of UAV teleoperation and reduce operator workload. The approach taken is to apply haptic feedback, i.e., provide information regarding the UAV motion relative to the environmental constraints through the sense of forces on the control device. The research approach consists of the development of an artificial force field that maps environmental constraints to virtual forces that can be used for haptic feedback to the operator. Different implementations of haptic feedback is investigated. The virtual forces can be presented as external forces on the haptic control device (force feedback), as an increase in the spring constant of the control device (stiffness feedback), or a combination of both techniques (force-stiffness feedback). Additionally, effects of signal transmission time delays due to, for example, a satellite communication is investigated and a method, the so-called wave variable transformation, is provided to reduce the negative effects of time delays. Finally, a model of the neuromuscular system of the human arm is used in offline simulations for tuning of the haptic feedback. From the findings in this thesis, it can be concluded that, generally, the use of haptic feedback significantly increases the level of safety, at the cost, however, of higher operator physical control effort. When operators are more aware of the safety-benefit with haptic feedback, then they are willing to accept this higher physical load and the overall subjective workload will not increase. When time delays are present, haptic feedback can maintain the high level of safety using wave variables. Force-stiffness feedback has the potential to further increase the level of safety without higher operator workload levels, and it can therefore be considered to be the main candidate to further improve haptic feedback in UAV teleoperation. Finally, in an early stage of haptic feedback design it is not necessary to use a model of the neuromuscular system. However, for tuning and further optimization a neuromuscular model is an important tool.
Application of ISO 9000 Standards to Education and Training.

Although ISO 9000 certification is still a marginal phenomenon in the education and training world, the numbers of certified institutions and departments are increasing particularly amongst continuing and vocational education and training providers. But many practitioners in the education and training world wonder whether this development is the best way to improve quality within education and training institutions. For many the real added value of such a certification process remains doubtful, not to mention costly.
