Letter health consultation : foundry slag used for road rock, Washington County, Iowa (2008)

A resident within one of the counties in your region has expressed some concern regarding potential adverse health effects from dust and material that may be found within foundry slag that has been used as a replacement for road rock. This consultation includes a comparison of nuisance issues from dust generated from a road constructed of foundry slag and dust generated from a road constructed from typical road rock. This consultation also includes a discussion of the potential health effects of exposure of heavy metals from incidental ingestion of foundry slag.

1011-006 Competine Creek Watershed Final Report

The Competine Creek watershed is a 24,956 acre sub-watershed of Cedar Creek. The creek traverses portions of three counties, slicing through rich and highly productive Southern lowa Drift Plain soils. The watershed is suffering from excessive sediment delivery and frequent flash floods that have been exacerbated by recent high rainfall events. Assessment data reveals soil erosion estimated to be 38,435 tons/year and sediment delivery to the creek at 15,847 tons/year. The Competine Creek Partnership Project is seeking WIRB funds to merge with IDALS-DSC funds and local funds, all targeted for structural Best Management Practices (BMPs) within the 2,760 acres of High Priority Areas (HPAs) identified by the assessment process. The BMPs will include grade stabilization structures, water and sediment basins, tile-outlet terraces, CRP, and urban storm water conservation practices. In addition, Iowa State University Extension-Iowa Learning Farm is investing in the project by facilitating a crop sampling program utilizing fall stalk nitrate, phosphorous index, and soil conditioning index testing. These tests will be used by producers as measures of performance to refine nutrient and soil loss management and to determine effective alternatives to reduce sediment and nutrient delivery to Competine Creek.

06014-007 Lower Coldwater-Palmer Creek Watershed Final Report

Lower Coldwater and Palmer Creeks in Butler and Floyd counties are subwatersheds of the Cedar River, which provides drinking water to Cedar Rapids, IA. The increasing concentration of nitrate+nitrate in the river is of concern to the Cedar Rapids water utility, and IDNR snapshot monitoring shows Coldwater and Palmer to be significant potential sources (above the 90th percentile for subwatersheds monitored). Both creeks are also on the Iowa Section 303(d) list of impaired waters (aquatic life). Citizens of these predominantly agricultural watersheds organized the Coldwater-Palmer Watershed Improvement Association to deal proactively with nonpoint source pollutants from crop and livestock operations through a performance-based environmental management program. The locally-adapted program implemented by the Coldwater-Palmer watershed council rewards participants for environmental accomplishments - soil quality improvement and nutrient source reduction as measured by accepted, scientifically-based tests and models. Most of the locally­appropriate BMPs used to improve performance are undertaken voluntarily at participants' initiative. WIRB funds will be combined with funding from the Iowa Com Growers Association and significant in-kind support from the Cedar River Watershed Monitoring Coalition, Iowa State University Extension and other partners. The project will result in sustainable reduction in nutrient loading achieved with voluntary participation of a majority of watershed farm operators.

1231-014 Twelve Mile Lake Watershed Final Report

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.

2015 Calendar Year Annual Report of the Watershed Improvement Review Board

The Watershed Improvement Fund and the Iowa Watershed Improvement Review Board (WIRB) were created in 2005. This statute is now codified in Iowa Code Chapter 466A. The fifteen-member Board conducted seven meetings throughout the year in-person or via teleconference. Meetings were held January 23, February 27, April 17, June 18, July 24, September 25 and December 17. Attachment 1 lists the board members and their organization affiliation. The Board completed one Request For Applications (RFA) for the Watershed Improvement Fund. The RFA was announced November 6, 2014 and closed December 29, 2014. December 29, 2014 Closing Date Request For Applications: The Board received 16 applications in response to this RFA. These applications requested $2.8 million in Watershed Improvement Funds and leveraged an additional $9.1 million for a total of $11.9 million of watershed project activity proposed. After reviewing and ranking the applications individually from this RFA, the Board met and selected eight applications for funding. The eight applications were approved for $1,249,861 of Watershed Improvement Funds. Data on the eight selected projects in this RFA include the following: • These projects included portions of 12 counties. • The $1.2 million requested of Watershed Improvement Funds leveraged an additional $4.2 million for a total of $5.4 million in watershed improvements. • Approved projects ranged in funding from $41,980 to $250,000. Attachment 2 lists the approved projects’ name, applicant name, project length, county or counties where located, and funding amount for the RFA. Attachment 3 is a map showing the status of all projects funded since inception of the program. At the end of 2015 there are 111 completed projects and 39 active projects. In cooperation with the Treasurer of State, the WIRB submitted the 2015 year-end report for the Rebuild Iowa Infrastructure Fund to the Legislative Services Agency and the Department of Management. Attachment 4 contains the 2015 annual progress reports submitted from active projects or projects finished in 2015.

Iowa's Child Death Review Report to the Governor and General Assembly Annual Report 2008-2009

The goal of the Iowa Child Death Review Team is to identify those risks or factors in childhood (ages 17 and under) that result in fatal outcomes through a retrospective review of child death cases. A multidisciplinary team approach to reviewing child death cases is conducted. Recommendations made by the Team are based on data, which then are used to identify trends that require systemic solutions. In reviewing the number of child deaths in years 2008 and 2009, one can quickly discern that child death rates declined from 2008 to 2009, decreasing from 386 to 311 deaths. The incidence of child death was higher in those counties with greater populations within our state.

Do fire and seed additions alter strong seed timing and priority effects on prairie establishment?, 2011

Many prairie restoration projects are hampered by a lack of knowledge on how to restore the high diversity found in prairies, while at the same time preventing the establishment of a large weedy component. Methods are needed to increase diversity and abundance of native species while minimizing exotic species invasions in both 1) newly planted restorations and 2) established restorations. We established an experiment in Story and Monona counties in 2005 to determine the effects of different native cover crop species and timing of seeding on the establishment of new prairie restorations. We found that adding a 30-species prairie mix in early spring led to diverse native communities, but adding the mix in the late summer or the following year after cover crops established led to low diversity communities dominated by exotics. The identity of cover crops affected communities less than timing of seed additions. A second seed addition added to ash after a spring fire in the seventh year (Monona County site) increased recruitment from the prairie mix slightly, but the increase was not enough to cause convergence in the treatments. Surprisingly, the second seed addition increased diversity only in communities that were already the most diverse (i.e., in plots seeded with the prairie mix in early spring before cover crops established). These results imply that 1) cover crops are not effective for establishing prairie and 2) over seeding into established plots may not be an easy and efficient way to increase native recruitment and lower weedy species abundances. Therefore, focusing on establishing high levels of recruitment and diversity and excluding weedy species during the critical time early in establishment should be a priority for new projects.

Motor Grader Operator Maintenance of Granular Surfaced Roads : Tips from Iowa Operators, 1991

This booklet is a compilation of notes taken during motor grader operators workshops held at some 20 different locations throughout Iowa during the last two years. It is also the advice of 16 experienced motor grader operators and maintenance foremen (from 14 different counties around Iowa), who serve as instructors and assistant instructors at the "MoGo" workshops. The instructors have all said that they learn as much from the operators who attend the workshops as they impart. Motor grader operators from throughout Iowa have shown us new, innovative and better ways of maintaining gravel roads. This booklet is an attempt to pass on some of these "tips" that we have gathered from Iowa operators. It will need to be revised, corrected, and added to based on the advice we get from you, the operators who do the work here in Iowa.

2012 Iowa Small Hospital Improvement Program (SHIP) Briefing and Survey Report, January 22, 2013

In August of 2012 the Iowa State Office of Rural Health (SORH) conducted a survey to determine the value of the Small Rural Hospital Improvement Program (SHIP) in Iowa. This survey was distributed to the 84 participating hospitals however, because some hospitals network their SHIP funds we only asked the contract administrators of the contracts to complete the survey. 58 of the 78 SHIP contract administrators completed the survey (74%). Background: SHIP brings in roughly $750,000.00 annually to Iowa to assist small Iowa hospitals. Average distribution of approximately $7,500 per hospital. Seventy three of ninety nine Iowa counties are represented.

Laboratory diagnosis of brucellosis in a rural endemic area in northeastern Spain

Sera obtained from 62 patients from four mountain counties in Catalonia (Northeastern Spain), in whom brucellosis had been diagnosed on the basis of clinical evidence and/or personal history, were analyzed using the rose Bengal test, standard serum agglutination test (SAT), Coombs" test, ELISA, and complement fixation. The diagnosis was further confirmed through blood cultures. Clinical evidence, epidemiology, and the results from serologic tests were used to assign patients to one of two groups: group 1 (n = 38) patients had primary infections, whereas group 2 (n = 24) patients had been previously exposed to the microorganism, i.e. re-infection of group 2 individuals occurred after long periods of time during which no active infection by Brucella had been detected. Receivingoperating charts (ROC) were used to determine the diagnostic value of the different tests and to establish discriminant values. Blood culture was a valuable diagnostic tool in group 1 (0.92 sensitivity) but was inappropriate in group 2 (0.08). The combination of positive rose Bengal test and agglutination ≥1/160 was valid for diagnosis in group 1. In group 2, agglutination < 1/160 (including negative agglutination) did not rule out brucellosis. The combination of positive rose Bengal test and Coombs" test ≥1/320 was the best diagnostic criterion (0.8 specificity; 1 sensitivity). ELISA (for IgG, IgM, or both) did not improve diagnostic accuracy

Cambios y permanencias en las dinámicas sociodemográficas de los Pirineos españoles. El papel de los movimientos migratorios

En este trabajo pretendemos ofrecer una visión de conjunto de la demografía de los municipios y comarcas que conforman el espacio que convencionalmente definimos como los Pirineos. Un territorio que, con mayor o menor intensidad según las coyunturas, ha vislumbrado cómo sus efectivos poblacionales han ido disminuyendo dramáticamente a lo largo de todo el siglo XX. Sin embargo, en la última década y en estos primeros años de la nueva centuria, se están detectando cambios en sus negativas dinámicas demográficas, que reflejan a su vez modificaciones de las funciones socioeconómicas que una parte de los municipios pirenaicos desempeñan en la sociedad española. Los motores que vehiculan estas nuevas tendencias son, principalmente, la combinación de las funciones turística y residencial que ahora van a desarrollar una parte de estos municipios.

El Cort a Catalunya

El cort és una magistratura judicial local documentada des del tombant del segle XI al XII amb un caire representatiu comtal pròpia dels indrets repoblats tant sota domini del titular de Barcelona com de l’urgellenc, la qual es veurà afectada per la feudalització, pel desenvolupament urbà i per l’aplicació de fórmules romanistes, alhora que aviat serà espill de les relacions entre el poder municipal i la corona fins haver d’integrar-se, a partir del pas del segle XIII al XIV, en les institucions jurisdiccionals batliars i vicarials. Malgrat la seva arrelada presència, la historiografia sols n’ha apuntat determinats trets destacats gràcies a notoris treballs aïllats fruit, bàsicament, de l’esforç de Klüpfel i Lalinde, cosa que no ha impedit les evidents i excesssives dificultats actuals en la comprensió de la institució i el seu desenvolupament. Potser, doncs, és bo de contribuir a l’homenatge al Dr. Manuel Riu amb l’atenció posada en el cort, malgrat que la limitació d’espai disponible obliga a reduir l’aportació a l’esbós dels eixos articuladors de la figura i la seva evolució.

"Et hoc facimus propter necessitatem famis...". Possibilitats de les fonts documentals catalanes per a l'estudi de les crisis alimentàries dels segles X-XIII

European studies of famines before the thirteenth century have been based principally on chronicles and especially on information from monastic annals. These sources, which are especially numerous during the so-called Carolingian Cultural Renaissance, offer abundant evidence of a phenomenon scarcely mentioned in other types of sources, including archival sources: the frequency and gravity of crises of food supply in some regions of continental Europe during the central middle ages, an epoch which, being situated between the terrible famines of the carolingian period and the great panademics of the fourteenth century, has been considered a period “without famines.” The object of this article is to shed light on the limitations of medieval catalan chronicle sources for the reconstruction of food-supply crises which affected the catalan counties in the tenth through the thirteenth centuries and illustrate, in contrast, the multiple opportunities offered by sources from the lordly archives. A significant part of these archival sources are connected in a direct and indirect manner to the difficulties of the rural and urban populations during famines and therefore, in a broad sense, can be considered a consequence of these crises.

De la guerra de l'Empordà (1128) a la mortaldat de 1131: gènesi, extensió i extinció d'una fam. Per a una història de les crisis alimentàries a la Catalunya medieval

In the history of food shortages and subsistence crises which affected the Catalan counties during the eleventh and twelfth centuries, the famine of 1129-1131 deserves special mention. Originating in the war of 1128 involving the Empordà and neighboring counties, this famine affected the city of Barcelona and other points of Catalonia (Winter, 1131) and created conditions for the spread of a deadly epidemic (July 1130 -January 1132).
