Coerced Confusion? Local Emergency Policy Implementation After September 11
Authors: Hildebrand Sean 
Published: May 2015

AbstractThis study examines what motivates local emergency management officials to implement federal emergency management and homeland security policies within their own departments since the September 11 attacks. Pre-existing research claims there is confusion among local governments about potential changes to the role local emergency management services play before, during, and after natural, accidental, or terror related incidents. Meanwhile, additional research claims the federal disaster management policies (The National Response Plan, National Incident Management System, and Incident Command System) lack flexibility in implementation expectations, and there is limited cohesion among the layers of government, actors, and interests involved. This study asserts that something must spur local actors to comply with federal policy demands in their daily operations given how the post-September 11 policies change the field. The study specifically examines the effects of coercion, defined as actions taken by the federal government to force state and local implementers to comply with federal policy demands. Available federal grant dollars for emergency management and homeland security practices could make a dramatic difference to local emergency management operations, forcing these actors to comply with federal policy demands, even if it is in a begrudging fashion that deviates from traditional Comprehensive Emergency Management (CEM) principles.
Public road infrastructure inventory in degraded

Published: May 2015

Abstract
Recent advancement of land-based mobile mapping
enables rapid and cost-effective collection of highquality
road related spatial information. Mobile Mapping
Systems (MMS) can provide spatial information with subdecimeter
accuracy in nominal operation environments.
However, performance in challenging environments such
as tunnels is not well characterized. The Norwegian Public
Roads Administration (NPRA) manages the country’s
public road network and its infrastructure, a large segment
of which is represented by road tunnels (there are about
1 000 road tunnels in Norway with a combined length of
800 km). In order to adopt mobile mapping technology
for streamlining road network and infrastructure management
and maintenance tasks, it is important to ensure that
the technology is mature enough to meet existing requirements
for object positioning accuracy in all types of environments,
and provide homogeneous accuracy over the
mapping perimeter.

This paper presents results of a testing campaign performed
within a project funded by the NPRA as a part
of SMarter road traffic with Intelligent Transport Systems
(ITS) (SMITS) program. The testing campaign objective
was performance evaluation of high end commercial
MMSs for inventory of public areas, focusing on Global
Navigation Satellite System (GNSS) signal degraded environments.
Hydrodynamic modeling of stratified estuary: case study of the Jadro River (Croatia)
Authors: Ljubenkov Igor 
Published: May 2015

Abstract
The Jadro River with total length of 4.3 km and average annual discharge of 7.9 m3 s-1 is a relatively small river on the east coast of the Adriatic Sea, close to Split. Field campaign measurements were made to estimate salt intrusion in the Jadro estuary in July 2012. This measurement confirmed the stratified character of the estuary where fresh water flows in a thin layer over denser sea water. Furthermore, a numerical model was set up for simulating unsteady stratified flow without mixing between the layers. The model is applied for the Jadro River and field measurements are used for calibration. In addition, the steady state of stratification within the estuary is analyzed by a box model which assumes mixing between layers. Results of the numerical and the box models were compared. The flushing time estimated with the box model is approximately 1.5 day for summer steady conditions. Numerical analysis however shows that the residence time is much larger owing to flow unsteadiness
Water table effects on measured and simulated fluxes in weighing lysimeters for differently-textured soils
Authors: Wegehenkel Martin , Gerke Horst H. 
Published: May 2015

Abstract
Weighing lysimeters can be used for studying the soil water balance and to analyse evapotranspiration (ET). However, not clear was the impact of the bottom boundary condition on lysimeter results and soil water movement. The objective was to analyse bottom boundary effects on the soil water balance. This analysis was carried out for lysimeters filled with fine- and coarse-textured soil monoliths by comparing simulated and measured data for lysimeters with a higher and a lower water table. The eight weighable lysimeters had a 1 m2 grass-covered surface and a depth of 1.5 m. The lysimeters contained four intact monoliths extracted from a sandy soil and four from a soil with a silty-clay texture. For two lysimeters of each soil, constant water tables were imposed at 135 cm and 210 cm depths. Evapotranspiration, change in soil water storage, and groundwater recharge were simulated for a 3-year period (1996 to 1998) using the Hydrus-1D software. Input data consisted of measured weather data and crop model-based simulated evaporation and transpiration. Snow cover and heat transport were simulated based on measured soil temperatures. Soil hydraulic parameter sets were estimated (i) from soil core data and (ii) based on texture data using ROSETTA pedotransfer approach. Simulated and measured outflow rates from the sandy soil matched for both parameter sets. For the sand lysimeters with the higher water table, only fast peak flow events observed on May 4, 1996 were not simulated adequately mainly because of differences between simulated and measured soil water storage caused by ET-induced soil water storage depletion. For the silty-clay soil, the simulations using the soil hydraulic parameters from retention data (i) were matching the lysimeter data except for the observed peak flows on May, 4, 1996, which here probably resulted from preferential flow. The higher water table at the lysimeter bottom resulted in higher drainage in comparison with the lysimeters with the lower water table. This increase was smaller for the finer-textured soil as compared to the coarser soil.
A head loss model for homogeneous slurry transport for medium sized particles
Authors: Miedema Sape A. 
Published: May 2015

Abstract
Slurry transport in horizontal and vertical pipelines is one of the major means of transport of sands and gravels in the dredging industry. There exist 4 main flow regimes, the fixed or stationary bed regime, the sliding bed regime, the heterogeneous flow regime and the homogeneous flow regime. Of course the transitions between the regimes are not very sharp, depending on parameters like the particle size distribution. The focus in this paper is on the homogeneous regime. Often the so called equivalent liquid model (ELM) is applied, however many researchers found hydraulic gradients smaller than predicted with the ELM, but larger that the hydraulic gradient of liquid. Talmon (2011, 2013) derived a fundamental equation (method) proving that the hydraulic gradient can be smaller than predicted by the ELM, based on the assumption of a particle free viscous sub-layer. He used a 2D velocity distribution without a concentration distribution.
In this paper 5 methods are described (and derived) to determine the hydraulic gradient in homogeneous flow, of which the last method is based on pipe flow with a concentration distribution. It appears that the use of von Driest (Schlichting, 1968) damping, if present, dominates the results, however applying a concentration distribution may neutralise this. The final equation contains both the damping and a concentration distribution giving the possibility to calibrate the constant in the equation with experimental data. The final equation is flexible and gives a good match with experimental results in vertical and horizontal pipelines for a value of ACv = 1.3. Data of horizontal experiments Dp = 0.05-0.30 m, d = 0.04 mm, vertical experiments Dp = 0.026 m, d = 0.125, 0.345, 0.560, and 0.750 mm.
Spatial interpolation of point velocities in stream cross-section
Authors: Hasníková Eliška , Pavlásek Jiří , Vach Marek 
Published: May 2015

Abstract
The most frequently used instrument for measuring velocity distribution in the cross-section of small rivers is the propeller-type current meter. Output of measuring using this instrument is point data of a tiny bulk. Spatial interpolation of measured data should produce a dense velocity profile, which is not available from the measuring itself. This paper describes the preparation of interpolation models.
Measuring campaign was realized to obtain operational data. It took place on real streams with different velocity distributions. Seven data sets were obtained from four cross-sections varying in the number of measuring points, 24-82. Following methods of interpolation of the data were used in the same context: methods of geometric interpolation arithmetic mean and inverse distance weighted, the method of fitting the trend to the data thin-plate spline and the geostatistical method of ordinary kriging. Calibration of interpolation models carried out in the computational program Scilab is presented. The models were tested with error criteria by cross-validation. Ordinary kriging was proposed to be the most suitable interpolation method, giving the lowest values of used error criteria among the rest of the interpolation methods.
Investigation of seasonal thermal flow in a real dam reservoir using 3-D numerical modeling
Authors: Üneş Fatih , Varçin Hakan 
Published: May 2015

Abstract
Investigations indicate that correct estimation of seasonal thermal stratification in a dam reservoir is very important for the dam reservoir water quality modeling and water management problems. The main aim of this study is to develop a hydrodynamics model of an actual dam reservoir in three dimensions for simulating a real dam reservoir flows for different seasons. The model is developed using nonlinear and unsteady continuity, momentum, energy and k-ε turbulence model equations. In order to include the Coriolis force effect on the flow in a dam reservoir, Coriolis force parameter is also added the model equations. Those equations are constructed using actual dimensions, shape, boundary and initial conditions of the dam and reservoir. Temperature profiles and flow visualizations are used to evaluate flow conditions in the reservoir. Reservoir flow’s process and parameters are determined all over the reservoir. The mathematical model developed is capable of simulating the flow and thermal characteristics of the reservoir system for seasonal heat exchanges. Model simulations results obtained are compared with field measurements obtained from gauging stations for flows in different seasons. The results show a good agreement with the field measurements.
Treated wastewater irrigation effects on soil hydraulic conductivity and aggregate stability of loamy soils in Israel
Authors: Schacht Karsten , Marschner Bernd 
Published: May 2015

Abstract
The use of treated wastewater (TWW) for agricultural irrigation becomes increasingly important in water stressed regions like the Middle East for substituting fresh water (FW) resources. Due to elevated salt concentrations and organic compounds in TWW this practice has potential adverse effects on soil quality, such as the reduction of hydraulic conductivity (HC) and soil aggregate stability (SAS). To assess the impact of TWW irrigation in comparison to FW irrigation on HC, in-situ infiltration measurements using mini disk infiltrometer were deployed in four different long-term experimental orchard test sites in Israel. Topsoil samples (0-10 cm) were collected for analyzing SAS and determination of selected soil chemical and physical characteristics.
The mean HC values decreased at all TWW sites by 42.9% up to 50.8% compared to FW sites. The SAS was 11.3% to 32.4% lower at all TWW sites. Soil electrical conductivity (EC) and exchangeable sodium percentage (ESP) were generally higher at TWW sites. These results indicate the use of TWW for irrigation is a viable, but potentially deleterious option, as it influences soil physical and chemical properties.
Linear Regression Diagnostics in Cluster Samples
Authors: Li Jianzhu , Valliant Richard 
Published: May 2015

Abstract
An extensive set of diagnostics for linear regression models has been developed to handle nonsurvey data. The models and the sampling plans used for finite populations often entail stratification, clustering, and survey weights, which renders many of the standard diagnostics inappropriate. In this article we adapt some influence diagnostics that have been formulated for ordinary or weighted least squares for use with stratified, clustered survey data. The statistics considered here include DFBETAS, DFFITS, and Cook's D. The differences in the performance of ordinary least squares and survey-weighted diagnostics are compared using complex survey data where the values of weights, response variables, and covariates vary substantially.

Authors: Young Derek S. , Mathew Thomas 
Published: May 2015

Abstract
The role of statistical tolerance intervals for developing ratio edit tolerances in a parametric setup is investigated. The performance of the methodology is assessed for the normal and Weibull distributions. The numerical results show that in terms of Type I and Type II errors, statistical tolerance intervals exhibit better performance compared to other ratio edit procedures available in the literature. The methodology is illustrated using 2010 and 2011 data from the Annual Survey of Manufacturers.
Application of reduced doses of chlorsulfuron in semi-dwarf and full-height cultivars of winter triticale
Authors: Kaczmarek Sylwia , Matysiak Kinga 
Published: May 2015

Abstract
The aim of the field experiments carried out in the years 2009-2011 was to assess the application of reduced doses of chlorsulfuron on yield and quality parameters of winter triticale semi-dwarf and full-height cultivars. The herbicide effect was evaluated in two cultivars, Grenado and Pizarro. The cultivars were of different plant heights. Chlorsulfuron was applied at the recommended dose (15 g a.i. ∙ ha-1), at areduced dose (10.5 g a.i. ∙ ha-1) and at areduced dose with an adjuvant. Treatments with the herbicide were conducted directly after the triticale had been sown. Visual assessment of weed infestation was carried out in spring, after the start of the vegetation of the cultivated plant. The study assessed triticale grain yield, grain number per ear, thousand grain weight, and selected qualitative parameters of grain (protein and starch content). The obtained data proved the usefulness of reduced doses of chlorsulfuron in weed control both separately and in a combination with the adjuvant. The average percent of the weed control was very high for both cultivars and for the assessed doses of herbicide. Both experimental factors (herbicide dose and triticale cultivar) influenced the level of the obtained grain yield of triticale, and the thousand kernel weight. While grain number per ear and protein and starch content depended only on the examined cultivar

Abstract
The insecticidal effects of Eucalyptus dundasii Maiden essential oil was studied on the adults of the lesser grain borer, Rhyzopertha dominica (F.), and the saw-toothed grain beetle, Oryzaephilus surinamensis (L.). Essential oil was obtained by the hydro-distillation method and essential oil composition was analysed by GC-MS. Chemical analysis indicated that 1,8-cineole (54.15%), p-cymene (12.41%), α-thujene (11.37%), and E-caryophyllene (6.7%) were major constituents. For R. dominica and O. surinamensis, the LC50 of E. dundasii essential oil was 41.69 and 57.92 μl · l-1 of air, respectively. Increasing the concentration of the essential oil and the exposure time, increased mortality. The durability of fumigant toxicity on O. surinamensis adults was higher than on R. dominica adults and was statistically different. Based on the mean of the repellent indexes and the standard deviation, E. dundasii essence was repellent for both insects at 70, 140, and 280 μl · l-1 of air concentrations. Statistical analysis showed that Relative Growth Rate (RGR) in O. surinamensis was higher than in R. dominica, and the Relative Consumption Rate (RCR), the Efficiency of Conversion of Ingested food (ECI), and the Feeding Deterrence Index (FDI) in O. surinamensis was lower than in R. dominica. The many diverse bio-effects of E. dundasii essential oil confirmed that it is a good candidate for management of R. dominica and O. surinamensis

Abstract
The health state of Ginkgo biloba L. and damage caused by microscopic fungi were evaluated over the 2010-2011 time period, in selected localities of Slovakia and Czechia. The trees were assessed and put into two categories of health. Trees in very good (category 1) or good vitality and health with no or only light damage (category 2). A total of seven species of microscopic fungi were identified from samples taken from branches, fruits, and leaves. The following fungal genera were detected: Epicoccum, Fusarium, Alternaria, Phomopsis, Cylindrosporium, Phyllosticta, and Cladosporium. This present study is the first report about microscopic fungi determined on G. biloba for Slovakia
Biodiversity of segetal weed community in continuous potato cultivated with metribuzin-based weed control
Authors: Pawlonka Zbigniew , Rymuza Katarzyna , Starczewski Krzysztof , Bombik Antoni 
Published: May 2015

Abstract
The objective of the work reported here was to determine the relationship between herbicide rate and the biodiversity of weed communities in potato cultivated in continuous cropping. A seven-year field experiment was conducted to examine the effect of 4 metribuzin rates and an uncontrol on weed infestation in successive years of continuous potato cultivation. The following indices were calculated: the Shannon-Wiener and Simpson’s indices of species diversity and the Simpson’s index of domination. A total of 33 species were recorded in the experimental plots. Echinochoa crus-galli was the dominant species. The most abundant segetal communities were observed in untreated plots. An application of the herbicide reduced the biodiversity of the agrophytocenosis. Cultivation in continuous cropping increased the species number of the weed community in potato. The herbicide and cultivation in continuous cropping did not significantly affect the biodiversity indices but their values, to a great extent, confirmed the trends revealed by the analysis of weed infestation
Incidence of Phytophthora infestans (Mont.) de Bary on potato and tomato in Maine, 2006–2010
Authors: Olanya Ocen Modesto , Larkin Robert Philip , Honeycutt Charles Wayne 
Published: May 2015

Abstract
Late blight, caused by Phytophthora infestans (Mont.) de Bary, is a devastating disease which is found worldwide. In Maine, United States (US), we recorded late blight on potato and tomato during the 2006-2009 cropping seasons. From 2006 to 2008, over 90% of the diseased samples were collected in potato fields from northern and central Aroostook County in Northern Maine, US. Then, in 2009, an unprecedented influx of inoculum on infected tomato transplants shipped to retail garden centers throughout the Northeast US significantly changed the late blight infection patterns. In 2009, 43% of diseased samples obtained were from tomato, and 57% from potato, and disease was found to occur all over the state. Moran’s index and spatial autocorrelation analysis of disease occurrence, geographical locations, host factors, and infection levels from previous years, were not statistically significant (p > 0.05). Therefore, random distributions of late blight incidences were recorded across locations and years. Nearest neighbor analysis revealed that mean spatial distances for late blight occurrence ranged from 1.51 to 71.4 km from 2006 to 2008, and 7.4 to 126.5 km in 2009. The frequency and locations of late blight outbreaks in 2009 were substantially greater than in 2006, 2007, and 2008, as affected by the influx of inoculum and movement of infected tomato seedlings as well as conducive environmental conditions. All were contributing factors for late blight occurrence in Maine. In 2010, few disease samples were collected, indicating that the influx of inoculum in 2009 did not persist to cause widespread disease in 2010. The reduction of inocula sources, fungicide protection of susceptible hosts, and the removal and destruction of infected tomato seedlings and potato cull piles or volunteer plants, can greatly reduce late blight occurrences and improve potato production. These actions should be considered as an integral part of late blight management programmes in regions where late blight commonly occurs
Analytical and Numerical Investigation on the Duffing Oscilator Subjected to a Polyharmonic Force Excitation
Authors: Stoyanov Svetlin 
Published: May 2015

Abstract
An analytical solution for a specific case of the forced Duffing oscillator is proposed. The excitation force contains two harmonics with significant difference frequencies. This case corresponds to a presence of a defect in the machinery and is in the art of the machinery vibration diagnostics. The results obtained show an amplitude modulation. Therefore, the presence of an amplitude modulation in the vibration signal may be used as an indicator for a malfunction. Analytical solution derived clarifies how the amplitude modulation occurs. Also, a numerical solution is realized and compared with the analytical one. For this, the Duffing equation is solved numerically and then, the spectrograms of vibrations are obtained through a Discrete-time Fourier Transform.
Deterministically – Probabilistic Approach for Determining the Steels Elasticity Modules
Authors: Popov Alexander , Klitcheva Galina 
Published: May 2015

Abstract
The known deterministic relationships to estimate the elastic characteristics of materials are not well accounted for significant variability of these parameters in solids. Therefore, it is given a probabilistic approach to determine the modules of elasticity, adopted to random values, which increases the accuracy of the obtained results. By an ultrasonic testing, a non-destructive evaluation of the investigated steels structure and properties has been made.
