Investigations of Bulk Dynamic Threshold-Voltage MOSFET with 65 GHz “ Normal-Mode ” Ft and 220 GHz “ OverDrive Mode ” Ft for RF Applications

The RF properties of bulk dynamic threshold-voltage MOSFET (B-DTMOS) with a deep n-well isolation was investigated both under the normal DTMOS mode and two newly-proposed DTMOS operation modes: moderate (0.6V < Vgs=Vbs <0.85V) and over-drive ( Vgs=Vbs > 0.85V) modes. While Ft can be improved to 65GHz at 12.5mA with 1.5V Vds bias under normal-mode DTMOS operation, a high Ft of 220GHz with good linearity and stability is achieved under over-drive mode of operation.
Robustness Analysis of Eigenstructure Assignment Controllers on Rigid-Flexible Satellites

Flexible spacecraft with attached solar panels may exhibit undesired vibrations and structural deformations. These types of vehicles show an intrinsic coupling of the elements of the structure. The attitude maneuvers performed by flexible spacecraft may cause non-desired deflections of attached flexible elements. Any attitude and orbit control system generally solves these problems using filters that are designed to attenuate the relative deflections of flexible appendages. In this paper, we propose a method for designing attitude static controllers using an eigenstructure assignment (EA) method. A set of requirements were specified from our understanding of the system modes in an open loop. Exhaustive theoretical and numerical simulations were performed on special cases to verify the controller design procedure. In the design of the controller, we considered all of the aspects that relate to the eigenstructure assignment. The primary objective of this paper is to demonstrate the feasibility of obtaining a high degree of decoupling for some selected modes via the application of an EA method. Finally a robustness analysis is perform to the system together with the designed controller by means of a mu-analysis
Orbit Refinement with the STARE Telescope

The proposed Space-Based Telescopes for Actionable Refinement of Ephemeris (STARE) mission, which will consist of a constellation of nano-satellites in low Earth orbit (LEO), intends to refine orbits of satellites and space debris to less than 100 meters uncertainty in order to help satellite operators prevent collisions in space. To prove this is possible, a prototype STARE payload was used to refine the orbit of NORAD 27006 using a series of six ground-based images captured over a 60 hour period. The refined orbit, based on the first four observations made within the initial 24 hours allowed for prediction of the satellite’s trajectory to within less than 50 meters over the following 36 hours, as verified by the final two observations taken within that period. This paper describes the tools and methodology used to capture the images of NORAD 27006 and refine its orbit—the same ones that will be used during the STARE mission. The details of verifying the accuracy of the orbit over the next 36 hours are then presented, lending credence to the capability of STARE to accomplish its mission objectives.
A comparis on between a traditio nal and a geometri ca l supervis ed classifi er to produce land cover maps from SPOT5 images

The new high-resolution images from the satellites as IKONOS, SPOT5, Quickbird2 give us the opportunity to map ground features, which were not detectable in the past, by using medium resolution remote sensed data (LANDSAT). More accurate and reliable maps of land cover can then be produced. However, classiication procedure with these images is more complex than with the medium resolution remote sensing data for two main reasons: irstly, because of their exiguous number of spectral bands, secondly, owing to high spatial resolution, the assumption of pixel independence does not generally hold. It is then necessary to use new spectral classiiers taking into account also proximal information. In this view, it is necessary to combine both “spectral” and “spatial” features to optimise land use classiication. Standard supervised classiication techniques, so-called “per-pixel” classiiers, use only spectral information of remote sensing image, whereas neglecting the relationships between neighbouring pixels. The objective of this work is the comparison between a conventional supervised classiier, as “Maximum Likelihood” algorithm, and a spatial classiier based on a searching algorithm of a given geometrical pattern. The data in this study were a remote sensing image taken by SPOT5 satellite in July 2007 and used to discriminate the water melon cover class. Applying the object recognition tecnique the overall accuracy increased of about 12%.
REFLECTION CHARACTERISTICS OF 1-D EBG GROUND PLANE AND ITS APPLICATION TO A PLANAR DIPOLE ANTENNA

A one-dimensional electromagnetic bandgap (1-D EBG) ground plane was designed and characterized. The 1-D EBG ground plane, composed of metal patches, metal lines, and a ground plane, has in-phase re∞ection characteristics when the polarization of the incident electromagnetic waves is parallel to the direction of the EBG unit- cell array. The proposed 1-D EBG ground plane was applied to the design of low-proflle directive dipole antennas. The radiators of the designed antennas could be placed very close to the 1-D EBG ground plane without noticeable performance degradation of the antennas. In particular, the dipole antenna designed with the 1-D EBG ground plane and directors has higher directivity and a better F-B (front- to-back) ratio as compared to a conventional dipole antenna backed with a normal ground plane.
Final Report Mechanisms of mutation in Escherichia coli : analysis , engineering and applications

Spontaneous mutations arising in prokaryotes are the basis of several problematic phenomena, e.g. antibiotic resistance of pathogens, reduced production yield of industrial producer strains, or sequencing errors due to alteration of cloned sequences. We have previously narrowed the mutational repertoire of Escherichia coli by removal of all mobile DNA elements (insertion sequences, prophages, recombination hot spots) in a large scale genome-reduction effort (Pósfai et al., 2006). In this work, we demonstrate that the lack of transposable elements aids in the cloning and expression of a heterologous protein, which is otherwise rapidly inactivated by insertion sequences (ISes) disrupting its gene with a high frequency (Umenhoffer et al., 2010). To prevent recontamination of the IS-free bacterial genome by transposable elements during generalized phage transduction, we have removed the resident IS1 element from the genome of phage P1vir, commonly used for strain engineering (Fehér et al., 2011a). We further decreased the mutation-generating potential of E. coli by removal of the genes of three error-prone DNA polymerases, thereby significantly reducing the rate of point mutations. In addition, we have developed a method to measure the selective advantage conferred by a single IS element residing in the bacterial genome, compared to an IS-free host. This system uses competition experiments of fluorescently labeled IS-containing and IS-free cells, and was developed to systematically map the environments that activate IS element transposition. We used this technique to “replay evolution”, and demonstrate that the historic invasion and expansion of IS-elements in enterobacterial genomes was most probably fueled by the selfish (replicative) nature of the elements, and not by the selective advantage they conferred to their hosts (Fehér et al., 2011b).
TOWARDS A GEOGRAPHY OF TOURISM

Pearce, Douglas G. , "Towards a Geography of Tourism," Annals of Tourism Research, July/September 1979, VI(3):245-272. This paper traces the development of geographical interest in tourism during the past half century and examines the range and scope of the geography of tourism. The available literature is reviewed and suggestions are made regarding possible research avenues and theoretical developments. Six major areas of interest are identified: spatial aspects of supply, spatial aspects of demand, the geography of resorts, patterns of movements and flows, the impact of tourism, and models of tourist space. Through an emphasis on spatial interaction an attempt is made to provide some cohesion and synthesis for this body of knowledge which constitutes the basis of the geography of tourism. Keywords: geography, spacial processes, demand, supply, flows, resorts, impact, models.
The Implementation of Nursing Process and Associated Factors among NursesWorking in Debremarkos and Finoteselam Hospitals, Northwest Ethiopia, 2013

Background: The aim of this study was to describe the level of implementation of nursing process and associated factors among nurses working in DebreMarkos Referral Hospital and Finote Selam District Hospital, northwest Ethiopia, 2013. Materials and methods: A total of 124 nurses with one year and above working experience in the respective hospitals gave complete response out of 139 total nurses. Self-administered questionnaire from standardized and pre-tested tool were adopted to collect data. The data was entered using Epidata version3.1 and analyzed using SPSS software. In addition to descriptive statistics both bivariate and multivariate logistic regression model fitted to identify possible factors associated with nursing process implementation. Then those variables with P-value of <0.05 at 95% confidence interval (CI) was declared as statistically significant. Results: Among 124 total respondents 72 (58.2%) were female nurses, the ages of the respondents were between 20 and 62 years with median age of 29 years. They implemented nursing process at various degree of consistency 46 (37.1%) practice it very much, 62 (50%) practiced somewhat and the rest 16 (12.9%) not at all and not really practiced. Low knowledge negatively associate with nursing process implementation, Adjusted odds Ratio (AOR) 0.16, at 95% CI=0.07-0.39) and Presence of patients with uncomplicated case facilitate nursing process implementation (AOR=5.67, at 95% CI=2.52-12.73). Conclusion: The level of nursing process implementation is low among nurses. Factors associated with implementation of nursing process among nurses working in hospitals were; presence of patients with complicated case and low level of knowledge about nursing process. Nurses’ patient care knowledge in general and
THE INFLUENCE OF PREY AVAILABILITY AND HABITA T ON ACTIVITY PATTERNS AND ABUNDANCE O F ,ARGIOPE KEYSERLINGI (ARANEAE : ARANEIDAE )

I examined habitat relationships and prey abundance to determine which (if either) of thes e factors was more important in determining the local density patterns of the Saint Andrew's Cross spider, Argiope keyserlingi Karsch. Focusing on the relationship between a predator and its prey distribution presupposes that prey capture rate is crucial to the biology of the predator . I also studied the influence of prey capture on survival , reproduction and behavior of A. keyserlingi as a test of this assumption. Reproduction of females was influence d by food availability under laboratory conditions. Survival was higher among individual females provided wit h supplemental food in a field experiment . Adult female A. keyserlingi moved less frequently when they were provided with supplemental food. Featuresof vegetation were correlated with patternsof spatial distribution of this spider. There was a highly significant correlation between spider density on the study plots and the densit y of the understory shrubs that were favored as web sites. On a broad scale, seasonal phenology of activity in A. keyserlingi was positively correlated with potential prey abundance . At the scale of individual study plots, ther e is evidence that prey distribution was unpredictable in both time and space and that neither the activity pattern s nor local density of Argiope keyserlingi tracked these fluctuations.
The Reynolds number effects and numerical modelling of microburst-like wind and the wind drag acting on staggered arrays

The present study investigates the Reynolds numbers effects of the microburst-like wind, the numerical scheme necessary for modelling the flow as well as the wind drag force acting on staggered arrays of blocks near the surface using Computational Fluids Dynamics techniques. To the authors’ knowledge, these aspects of the microburst-like wind characteristics have never been studied before elsewhere. Steady-state Reynolds Averaged Navier-Stokes (RANS) technique is employed in the present study. The results of the Reynolds number effect is consistent with published experimental study. The Total Diminishing Variation (TDV) scheme for the convection term yield the best results for modeling impinging jet which is used to emulate microburst-like near-surface wind. The drag force is affected by the plan and frontal area index of the staggered array and pressure drag contributed the most to the total drag acting on the staggered arrays.
Implementing spatially explicit wind-driven seed and pollen dispersal in the individual-based larch simulation model: LAVESI-WIND 1.0

Abstract. It is of major interest to estimate the feedback of arctic ecosystems to the global warming we expect in upcoming decades. The speed of this response is driven by the potential of species to migrate, tracking their climate optimum. For this, sessile plants have to produce and disperse seeds to newly available habitats, and pollination of ovules is needed for the seeds to be viable. These two processes are also the vectors that pass genetic information through a population. A restricted exchange among subpopulations might lead to a maladapted population due to diversity losses. Hence, a realistic implementation of these dispersal processes into a simulation model would allow an assessment of the importance of diversity for the migration of plant species in various environments worldwide. To date, dynamic global vegetation models have been optimized for a global application and overestimate the migration of biome shifts in currently warming temperatures. We hypothesize that this is caused by neglecting important fine-scale processes, which are necessary to estimate realistic vegetation trajectories. Recently, we built and parameterized a simulation model LAVESI for larches that dominate the latitudinal treelines in the northernmost areas of Siberia. In this study, we updated the vegetation model by including seed and pollen dispersal driven by wind speed and direction. The seed dispersal is modelled as a ballistic flight, and for the pollination of ovules of seeds produced, we implemented a wind-determined and distance-dependent probability distribution function using a von Mises distribution to select the pollen donor. A local sensitivity analysis of both processes supported the robustness of the model's results to the parameterization, although it highlighted the importance of recruitment and seed dispersal traits for migration rates. This individual-based and spatially explicit implementation of both dispersal processes makes it easily feasible to inherit plant traits and genetic information to assess the impact of migration processes on the genetics. Finally, we suggest how the final model can be applied to substantially help in unveiling the important drivers of migration dynamics and, with this, guide the improvement of recent global vegetation models.
A Note on Income Heterogeneity, Dietary Choice and Medical Services: Implications for Health Outcomes

We present a theoretical framework where agents take into account the fact that their dietary choice affects their health status and hence their life expectancy. The literature that explains the relationship between income heterogeneity, health status and life expectancy has focused on the medical service channel whereby the wealthier spend more on medical services. In this note we propose an alternative mechanism -- the dietary choice channel. This channel takes into account how the quality of food directly impacts an individual's health and life expectancy. service channel whereby the wealthier spend more on medical services. In this note we propose an alternative mechanism – the dietary choice channel. This channel takes into account how the quality of food directly impacts an individual's health and life expectancy.
Detection of KHV in Freshwater Mussels and Crustaceans from Ponds with KHV History in Common Carp (Cyprinus carpio)

Characterization of asymptomatic KHV carriers may help understand virus transmission and storage. Such information allows farmers to minimize KHV on farms where this virus is present, also in common carp (Cyprinus carpio) monocultures. As asymptomatic KHV carriers, freshwater mollusks from the Unionidae family (swan mussels, Anodonta cygnea) and crustaceans from the Gammaridae family (scud, Gammarus pulex) were studied because of their unique method of feeding by accumulating bacterial and viral particles. The KHV genome was detected by nested PCR and confirmed by PCR recognizing the KHV glycoprotein gene in ORF 56 (KHV-U). Both PCR and nested PCR, which recognize the KHV thymidine kinase gene, always produced negative results in the swan mussels and scud samples.
The Continuing Education of Faculty as Teachers at a Mid-Sized Ontario University.

The findings outlined in this paper are the result of focus groups conducted with faculty at a mid-sized Ontario university. These nine faculty, all of whom have received awards of excellence from their university for their teaching, shared their insights about how they developed as teachers over time. More specific topics explored were as follows: how they first learned about teaching; how they continue to learn about teaching; resources that might have helped early in their teaching careers at the university; and advice they have about teaching for new university teachers, mid-career teachers, and teachers approaching retirement. While many of the observations offered here are specific to Ontario and some of the literature review is North American in focus, the paper offers valuable insights into how faculty learn to be teachers which may be helpful to universities around the world.

An investigation into the impact of total quality management application in the construction industry (a case of training)

Training helps individuals and organizations to improve for quality, competitiveness, productivity, incoming changes and set out future ideas. The paper aimed at investigating the impact of total quality management to the construction industry in Nigeria with a view to ascertaining if the application of total quality management has led to significant success to project delivery and assess the impact of training on project workers in achieving quality products in the construction industry in Nigeria. Relevant literatures were reviewed through primary and secondary sources of information. Well-structured questionnaire forms were sent out to stakeholders in the construction industry in the study areas. Responses from respondents were analyzed using simple percentages and hypothesis statements analyzed with multiple regression and correlation analyses. It was discovered that the application of total quality management to the construction industry has led to significant project delivery and that adequate training of project staff is a critical factor for successful total quality management application to construction projects. The paper recommends that workers be trained regularly. The choice of training method adopted must be given utmost consideration. The method selected will depend on the needs of the organization, employees and technological changes.
Toxicological Risk Assessment of Emerging Nanomaterials: Cytotoxicity, Cellular Uptake, Effects on Biogenesis and Cell Organelle Activity, Acute Toxicity and Biodistribution of Oxide Nanoparticles

The lack of toxicological data on nanomaterials makes it difficult to assess the risk related to their exposure, and as a result further investigation is required. This chapter presents the synthesis of controlled oxide nanoparticles followed by the evaluation of their safety profile or toxicity (iron, titanium and zinc oxides). The controlled surface chemistry, dis persion in several media, morphology and surface charge of these nanoparticles are pre - sented (transmission electron microscopy, dynamic light scattering, zeta potential, X-ray photoelectron spectroscopy). Classical cytotoxic and cellular uptake studies on different cancer cell lines from liver, prostate, heart, brain and spinal cord are discussed. The inci dence of nanoparticles on biogenesis and activity of cell organelles is also highlighted, as well as their biodistribution in animal models. The acute toxicity on zebrafish embryo model is also presented. Finally, the stress is put on the influence and the necessity of controlling the protein corona, a layer of plasma proteins physically adsorbed at the sur face of such nanoparticles as a result of their presence in the bloodstream (or relevant biological fluids). composition, size, surface functionalisation
Diogene: a Semantic Web-Based Automatic Brokering System

The aim of the European funded project Diogene (which is going to be closed the 31 of October 2004) [Diogene] has been the construction of an automatic “brokering environment” for e-learning in a Semantic Web scenario. The Diogene platform is able to act as an intermediary between the learners and different “content providers”, specialized training organisations which provide learning material suitably indexed by means of common Semantic Web standards and following a knowledge representation paradigm developed during the project [Capuano 2002, Capuano 2003]. This proposed knowledge representation framework on one hand allows teachers (or “learning designers”) to easily represent pedagogic information and on the other hand the system to efficiently reason about such information in order to assembly and personalize the learning material while answering the student’s training requests.
