The Mississippi River Trail (MRT) is a world-class bicycle trail that will follow the Mississippi River all the way from its headwaters in Minnesota to the Gulf of Mexico. The trail is partially completed; much of it is still in the planning and development stages. When complete, the MRT will Link over 2,000 miles of recreational trails through 10 states, including 280 miles in Iowa. Designated as a National Millennium Trail, the MRT will preserve natural environments along the river, stimulate economic growth in river communities, and provide bicyclists access to a variety of landscapes, history, and culture. The Iowa Department of Transportation commissioned the Center for Transportation Research and Education at Iowa State University to develop a plan for a safe, economically beneficial, and scenic MRT route through Iowa. This report presents the MRT plan for Iowa. It is organized in the following chapters: Executive Summary; (1) Introduction - vision statement and objectives; (2) Iowa MRT Minimum Design Standards; (3) Iowa MRT Route Analysis; (4) Recommended Improvement Plan; (5) MRT Implementation; and (6) Estimated Benefits and Impacts of the Iowa MRT. Additional information is provided in the following appendices: (A) GIS Analysis for the MRT; (B) Iowa MRT Maps; (C) Public Input; (D) Public Comments; and (E) References.

Dry Run Creek Watershed was designated an impaired waterbody by DNR in 2002, following an assessment of the biota in the stream by DNR Biologist, Tom Wilton. Subsequent studies by IOWATER Snapshot effort in 2003, found e-coli bacteria concentrations and high nitrate readings in excess of the State of Iowa limits for recreational streams. The Dry Run Creek Watershed Improvement Project is comprised of five major components. Three components will feature demonstrations of structural best management practices (BMPs) to protect water quality in Dry Run Creek. The fourth is an educational workshop to "kick-off" the initiative and background the stakeholders of the watershed in new stormwater management strategies for water quality protection. The fifth is a monitoring program that will provide data on the effectiveness of the practices to be demonstrated. Measurable outcomes from these projects include monitoring to document the effectiveness of infiltration­ based BMPs to reduce pollutant loading in urban stormwater runoff and reducing the volume of stormwater discharged directly into Dry Run Creek via storm sewer flows. Understanding of and social acceptance of new stormwater strategies and practices will also be monitored by surveys of watershed stakeholders and compared to findings of a survey done before the start of the project.

An overall effort has been initiated to improve the quality of the Yellow River in Northeast Iowa by reducing the amount of sediment and bacteria entering the stream. Funding for this project will be utilized to improve stream quality to the level of fully supporting game fish such as brown, rainbow and brook trout, walleye, northern pike and smallmouth bass. The Yellow River has the potential to be one of the top trout streams, not only in Iowa, but in the entire Upper Midwest. This project will greatly enhance recreational activities such as fishing, canoeing and inner tubing and will greatly increase tourism dollars to the state. The project will specifically address two sources of impairment: stream bank erosion and coliform bacteria from both livestock and inadequate human septic systems.

Clear Lake, Iowa's third largest natural lake, is located in Cerro Gordo County in north-central Iowa. The lake is a premier natural resource and popular recreational destination in north central Iowa, providing more than $40 million dollars annually to the local economy. Despite the lake's already strong recreational use, water quality concerns have not allowed the lake to reach its full recreational potential. Clear Lake is listed on Iowa's 2004 303(d) Impaired Waters List due to excessive levels of phosphorus, bacteria, and turbidity. Urban storm water runoff from the 8,600 acre watershed is a significant contributor to Clear Lake's impairment. There are over 68 storm water outlet points in the Clear Lake watershed that allow untreated urban runoff to empty directly into Clear Lake. Local governments have been very active in installing storm water Best Management Practices (BMPs) at as many of the outlets that current funding allows. To date, 11 of the 68 sites (16%) have been protected. These improvements have been very effective in reducing contaminants in the storm water runoff, but the remaining outlets still need protection. The first phase of this grant request is for an investigation of 10 storm water outlet sites to determine the most cost effective BMP for each site. The second phase of the grant request is to implement the BMPs deemed most cost effective at 5 of the 10 sites investigated. The grant request addresses one of the main priorities of the Iowa Watershed Improvement Grant: storm water runoff.

Clear Lake, Iowa's third largest natural lake, is a premier natural resource and popular recreational destination in north central Iowa. Despite the lake's already strong recreational use, water quality concerns have not allowed the lake to reach its full potential. Clear Lake is listed on Iowa's Draft 2010 303(d) Impaired Waters List for algae, bacteria, and turbidity. Many restoration practices have been implemented to treat the algae and turbidity impairment, but few practices have been installed to treat bacteria. Reducing beach bacteria levels is a priority of the lake restoration partners. Federal, State, and local partners have invested more than $20 million in lake and watershed restoration efforts to improve water clarity and quality. These partners have a strong desire to ensure high bacteria levels at public swim beaches do not undermine the other water quality improvements. Recent bacteria source tracking completed by the State Hygienic Laboratory indicates that Canada Geese are a major contributor of bacteria loading to the Clear Lake swim beaches. Other potential sources include unpermitted septic systems in the watershed. The grant request proposes to reduce bacteria levels at Clear Lake's three public swim beaches by utilizing beach cleaner machines to remove goose waste, installing goose deterrents at the swim beaches, and continuing a septic system update grant program. These practices began to be implemented in 2011 and recent bacteria samples in 2012 are showing they can be effective if the effort is continued.

Twelve Mile Creek Lake is a 660 acre, Significant Publicly Owned Lake with a watershed of 14,820 acres for a ratio of 21:3. The watershed is predominately privately owned agricultural land that originates in Adair County and drains into the lake which serves as the primary source water for the City of Creston, Union County and the seven counties served by the Southern Iowa Rural Water Association. In recent years, frequent algae blooms and recurrent spikes in suspended solid concentrations have been inflating water treatment expenses for the Creston Municipal Utilities (CMU). Declining trends in water quality spurred CMU to enlist the Union Soil and Water Conservation District (SWCD) to assist in evaluating watershed conditions for potential upland improvements. Significant gully erosion issues that had been previously underestimated were discovered during this watershed assessment process. Newly acquired LiDAR elevation data readily revealed this concern which was previously obscured from view by the dense tree canopy. A Watershed Development and Planning Assistance Grant Application was approved and funded by the Iowa Department of Ag and Land Stewardship- Division of Soil Conservation. Throughout the planning process, project partners innovatively evaluated and prioritized a number of resource concerns throughout the watershed. The implementation plan presented will thwart these threats which left unaided will continue to diminish the overall health of the system, reduce the appeal of the lake to recreational users, and contribute to higher water treatment costs.

Waterloo Creek Watershed is a 30,610 acre area that straddles the Iowa and Minnesota border. The lower 43% of the watershed is in Iowa. Bee and Duck Creeks in Minnesota flow into Waterloo Creek in Iowa. Designated as a primary contact recreational stream as well as a high-quality, cold water stream in Iowa, Waterloo Creek is a popular destination for anglers and other nature enthusiasts. The stream was on the Iowa DNR’s “Impaired Waters List” in 2008 and 2010 for Escherichia coli (E. coli) bacteria. Samples collected in 2010 and 2011 showed higher levels of E. coli. at sites with cattle in close proximity to the stream and were generally greater after high rainfall events. Other factors affecting water quality are high turbidity levels and frequent flooding. There is a deficiency in upland land treatment and an abundance of conventional tillage which increases the amount of erosion and potential for surface runoff to carry sediment to the stream. A comprehensive watershed assessment and management plan have been completed for the watershed which identify the causes of and solutions to water quality impairments. The goals of this project are to 1) develop a formal working relationship between technical staff in Iowa and Minnesota, 2) identify specific locations for Best Management Practice (BMP) implementation, 3) reduce sediment loading to Waterloo Creek to improve aquatic habitat and decrease bacteria delivery, and 4) reduce flooding potential in the watershed. The following BMPs will be implemented to reach these goals: terraces, grade stabilization structures, pasture management, stream buffers, stream bank stabilization, and agricultural waste structures.

Exposure to solar ultraviolet (UV) light is the main causative factor for skin cancer. UV exposure depends on environmental and individual factors. Individual exposure data remain scarce and development of alternative assessment methods is greatly needed. We developed a model simulating human exposure to solar UV. The model predicts the dose and distribution of UV exposure received on the basis of ground irradiation and morphological data. Standard 3D computer graphics techniques were adapted to develop a rendering engine that estimates the solar exposure of a virtual manikin depicted as a triangle mesh surface. The amount of solar energy received by each triangle was calculated, taking into account reflected, direct and diffuse radiation, and shading from other body parts. Dosimetric measurements (n = 54) were conducted in field conditions using a foam manikin as surrogate for an exposed individual. Dosimetric results were compared to the model predictions. The model predicted exposure to solar UV adequately. The symmetric mean absolute percentage error was 13%. Half of the predictions were within 17% range of the measurements. This model provides a tool to assess outdoor occupational and recreational UV exposures, without necessitating time-consuming individual dosimetry, with numerous potential uses in skin cancer prevention and research.

Background: Interpersonal violence is a worldwide social reality which seems to increasingly affect even the safest of countries, such as Switzerland. In this country, road traffic accidents, as well as professional and recreational activities, are the main providers of trauma-related injuries. The incidence of penetrative trauma related to stab wounds seems to be regularly increasing in our ED. The question arises of whether our strategies in trauma management are adapted to deal efficiently with these injuries.Methods: To answer this question, the study analysed patients admitted for intentional penetrative injuries in a tertiary urban emergency department (ED) during a 23 month period. Demographics, conditions of the assault, injury type and treatments applied were analysed.Results: Eighty patients admitted due to an intentional penetrating trauma accounted for 0.2% of the surgical practice of our ED. The assault occurred equally in a public or a private context, mainly affecting young males during the night and the weekend. Sixty six patients (83%) were treated as out-patients. Only 10 patients needed surgery. None of them required damage control surgery. No patient died and the mean hospital stay was 5.5 days.Conclusions: The prevalence of stab wounds in Switzerland is low. These injuries rarely need complex, surgical procedures. Observational strategies should be considered according to the patient status.

Exposure to solar ultraviolet (UV) radiation is the main causative factor for skin cancer. UV exposure depends on environmental and individual factors, but individual exposure data remain scarce. UV irradiance is monitored via different techniques including ground measurements and satellite observations. However it is difficult to translate such observations into human UV exposure or dose because of confounding factors (shape of the exposed surface, shading, behavior, etc.) A collaboration between public health institutions, a meteorological office and an institute specialized in computing techniques developed a model predicting the dose and distribution of UV exposure on the basis of ground irradiation and morphological data. Standard 3D computer graphics techniques were adapted to develop this tool, which estimates solar exposure of a virtual manikin depicted as a triangle mesh surface. The amount of solar energy received by various body locations is computed for direct, diffuse and reflected radiation separately. The radiation components are deduced from corresponding measurements of UV irradiance, and the related UV dose received by each triangle of the virtual manikin is computed accounting for shading by other body parts and eventual protection measures. The model was verified with dosimetric measurements (n=54) in field conditions using a foam manikin as surrogate for an exposed individual. Dosimetric results were compared to the model predictions. The model predicted exposure to solar UV adequately. The symmetric mean absolute percentage error was 13%. Half of the predictions were within 17% range of the measurements. This model allows assessing outdoor occupational and recreational UV exposures, without necessitating time-consuming individual dosimetry, with numerous potential uses in skin cancer prevention and research. Using this tool, we investigated solar UV exposure patterns with respect to the relative contribution of the direct, diffuse and reflected radiation. We assessed exposure doses for various body parts and exposure scenarios of a standing individual (static and dynamic postures). As input, the model used erythemally-weighted ground irradiance data measured in 2009 at Payerne, Switzerland. A year-round daily exposure (8 am to 5 pm) without protection was assumed. For most anatomical sites, mean daily doses were high (typically 6.2-14.6 SED) and exceeded recommended exposure values. Direct exposure was important during specific periods (e.g. midday during summer), but contributed moderately to the annual dose, ranging from 15 to 24% for vertical and horizontal body parts, respectively. Diffuse irradiation explained about 80% of the cumulative annual exposure dose. Acute diffuse exposures were also obtained for cloudy summer days. The importance of diffuse UV radiation should not be underestimated when advocating preventive measures. Messages focused on avoiding acute direct exposures may be of limited efficiency to prevent skin cancers associated with chronic exposure (e.g., squamous cell carcinomas).

A variety of behavioral disorders occurring abruptly in patients with Parkinson's disease (PD) has been recently published and attracted considerable attention in the press. Taking the form of pathological gambling, compulsive shopping, addiction to Internet and to other recreational activities, hypersexuality or bulimia, impulse control disorders (ICD) related to PD are probably more frequent than previously appreciated and may have consequences as spectacular as disastrous for the involved patients. ICD are currently viewed as particular adverse reactions to antiparkinsonian medications, notably to dopamine agonists, and, accordingly, tend to improve or disappear when PD therapy is appropriately adjusted.

Introduction Our institution (University hospital) is encouraging physical activities for health through various popular sporting events in the city of Lausanne, the biggest of which is a road race of 2, 4, 10 and 20km. Objective To create an efficient and sustainable training program in preparation of the race for a group of motivated hospital employees without any prior experience with structured training and to identifying the benefits and limitations encountered.. Methods Subjects of various fitness levels were recruited by add and agreed to undergo lab and field testing before a 12-week 3 times/week running program, based on maximal aerobic speed (MAS-30/30 sec intervals), running technique exercises and endurance training. The interval session was the only one supervised. Their goal was the 10km (11 subjects) and the 20km (6 subjects). Results A group of 17 subjects (7 male and 10 female), mean age 36.6±7.3 years, VO2max 44.0±5.5 ml/kg/min, filed test interval MAS 15.1±2.4 km/h started the program. 2 were lost because of injury (while skiing). Adherence to interval sessions was excellent, although 3 weekly training sessions proved to be difficult for most of the subjects. Performance in the race was satisfying for all of them, 6/7 subjects having improved their running time from the previous year, the others participated for the first time and 7/8 completed the race satisfyingly, one DNF-ed because of sinusitis. Repeat MAS field test was available for 6 subjects, who improved by 5.9% (p<0.01). Subjectively, all of the participants were very satisfied with improvement, interaction with colleagues from various professions, and with self achievement and confidence. Conclusions Implementation of a structured training program for recreational or non-athletes can be very successful in creating a better self-confidence, a better working environment inside a hospital facility and obviously in improvement of physical fitness and athletic performance. Above all, it can only encourage health institutions to promote the health of their own employees through physical activity, which can allow people to connect through sports. As a result, subjects in this study tend to encourage other employees to be more active and are hungry for more advice and continued offers for physical activities benefiting both them and the institution through better efficiency at work and less absenteeism common to more active people.

[eng] The individual work of the student, in the European space for higher education, takes a particular relevance. At the same time, in this context, a complex challenge is presented to the professors, in the educational and formative work aimed at the students as well as in the organization of educational plans. Among the different activities that the system of ECTS comprises, we can highlight the preparation and accomplishment of examinations. This fact means to integrate into the learning process the individual and autonomous work that the students have to carry out to acquire the knowledge and to surpass the evaluation test. To achieve this objective, a database including multiple choice questions with three possible answers has been developed (similar to those composing part of the Pharmaceutical Technology test). This database has a design that facilitates its use by professors and students interested in this area and allows as the interactive evaluation of obligatory and optional subjects from the formal point of view, as a corporate recreational environment to make their employment more attractive for the students. The edition of the Web page of the Pharmaceutical Technology Teaching Innovation Group of the UB has been used to place this database within everybody"s reach. [spa] El trabajo individual del alumno adquiere, dentro del marco europeo de educación superior, una particular relevancia. Al mismo tiempo, en este contexto, a los profesores se nos presenta un reto complejo, tanto en nuestra labor docente y formativa del alumno, como en la organización de los planes docentes. De las distintas actividades que engloba el crédito europeo podemos destacar la preparación y realización de exámenes, hecho que supone integrar en el proceso de aprendizaje el trabajo individual y autónomo que realiza el estudiante para adquirir los conocimientos y superar las pruebas de evaluación. Para conseguir este objetivo se ha planteado la elaboración de una base de preguntas con tres respuestas posibles (del tipo de las que componen parte de los exámenes de Tecnología Farmacéutica), en forma de base de datos con un formato que facilite su utilización por parte de profesores y alumnos interesados en este ámbito y que permita tanto la evaluación interactiva de las asignaturas troncales y optativas desde el punto de vista formal, como su aplicación en un entorno lúdico corporativo para hacer más atrayente su empleo por los estudiantes. Se ha aprovechado la edición de la página Web del Grupo de Innovación Docente de Tecnología Farmacéutica de la UB para ponerlo al alcance de todos.

Mushroom picking has become a widespread autumn recreational activity in the Central Pyrenees and other regions of Spain. Predictive models that relate mushroom production or fungal species richness with forest stand and site characteristics are not available. This study used mushroom production data from 24 Scots pine plots over 3 years to develop a predictive model that could facilitate forest management decisions when comparing silvicultural options in terms of mushroom production. Mixed modelling was used to model the dependence of mushroom production on stand and site factors. The results showed that productions were greatest when stand basal area was approximately 20 m2 ha-1. Increasing elevation and northern aspect increased total mushroom production as well as the production of edible and marketed mushrooms. Increasing slope decreased productions. Marketed Lactarius spp., the most important group collected in the region, showed similar relationships. The annual variation in mushroom production correlated with autumn rainfall. Mushroom species richness was highest when the total production was highest.
