2009 Iowa’s Rail System Background Prepared by the Office of Systems Planning December 2010

Iowa’s Rail Environment Iowa’s rail transportation system provides both freight and passenger service. Rail serves a variety of trips, including those within Iowa and those to other states as well as to foreign markets. While rail competes with other modes, it also cooperates with those modes to provide intermodal services to Iowans. In 2009 Iowa’s rail transportation system could be described as follows: Freight Iowa’s 130,000-mile freight transportation system includes an extensive railroad network, a well-developed highway system, two bordering navigable waterways, and a pipeline network as well as air cargo facilities. While rail accounts for only 3 percent of the freight network, it carries 43 percent of Iowa’s freight tonnage. A great variety of commodities ranging from fresh fish to textiles to optical products are moved by rail. However, most of the Iowa rail shipments consist of bulk commodities, including grain, grain products, coal, ethanol, and fertilizers. The railroad network performs an important role in moving bulk commodities produced and consumed in the state to local processors, livestock feeders, river terminals and ports for foreign export. The railroad’s ability to haul large volumes, long distances at low costs will continue to be a major factor in moving freight and improving the economy of Iowa. Key 2008 Facts • 3,945 miles of track • 18 railroads • 49.5 million tons shipped • 39.7 million tons received • 2 Amtrak routes • 6 Amtrak stations • 66,286 rail passenger rides Key Rail Trends • slightly fewer miles being operated; • railroads serving Iowa has remained the same; • more rail freight traffic; • more tons hauled per car; • higher average rail rates per ton-mile since 2002; • more car and tons hauled per locomotive; and • more ton miles per gallon of fuel consumed. Iowa’s rail system and service has been evolving over time relative to its size, financial conditions, and competition from other modes.

Best Practices for Low-Cost Safety Improvements on Iowa’s Local Roads, 2008

Many good maintenance practices are done routinely to ensure safe travel on low-volume local roads. In addition, there are many specific treatments that may go beyond the point of routine maintenance and in fact provide additional safety benefits with a relatively low price tag. The purpose of this publication is to try to assemble many of these treatments that are currently practiced in Iowa by local agencies into one, easy-to-reference handbook that not only provides some clarity to each treatment with photos and narrative, but also features references to agencies currently using that technique. Some strategies that are utilized by Iowa, other states, and are topics of research have also been included to allow the user more information about possible options. Even though some areas overlap, the strategies presented have been grouped together in the following areas: Signing and Delineation, Traffic "Calming," Pavement Marking and Rumble Strips/Stripes, Roadside and Clear Zone, Guardrail and Barriers, Lighting, Pavements and Shoulders, Intersections, Railroad Crossings, Bridges and Culverts, and Miscellaneous. The intention is to make this a “living” document, which will continue to be updated and expanded periodically as other existing practices are recognized or new practices come into being.

Ledivalaisimet rautatiealueiden valaistuksessa

Leditekniikan kehitys viime vuosina on mahdollistanut niiden käytön yleisvalaistuksessa. Tässä työssä tehdään katsaus leditekniikan nykytilaan ja tulevaisuuteen, sekä osoitetaan, että ledivalaisimien energiankulutuksessa ja huoltokustannuksissa tehdyillä säästöillä voidaan kattaa suuremmat hankintakustannukset ja päästä yhtä suuriin tai pienempiin elinkaarikustannuksiin verrattuna perinteisiin kaasupurkausvalaisimiin. Valaisimien määrät on laskettu Dialux-valaistuslaskentaohjelmalla siten että rautatieasemien avolaitureiden ja katettujen laitureiden valaistusvaatimukset täyttyvät. Tuloksia voi soveltaa muihin vastaaviin tiloihin kuten asematunneleihin tai kevyen liikenteen väylille.

Tony Biernacki Collection, 1967, 1979-1980, n.d.

Tony Biernacki's rowing career began in 1950 in Ottawa with his first Henley medal in 1952 in the coxless four. Sculling became his real means to success. Since 1955 he has posted record times and had numerous wins in the single. He represented Canada at the National Team between 1958 and 1967 and raced in the single at the British Empire Games and Pan Am Games (Chicago, silver medal) and pair at the Worlds in Yugoslavia in 1966. He won the Olympic trials in 1960 in Rome, but was unable to go. Upon his retirement from competition Tony was hired as the Team Manager for the following Pan Am Games. Tony was hired by Brock University in 1965 as a technician in the Chemistry Department. He became the head rowing coach that same year and began women’s rowing at the university level in Ontario with the first women’s crew in 1967. As Brock's second coach ever, he led the teams to championship form and kept the athletes racing through the summer regatta season. Tony remained at Brock from 1965 to 1980. He was one of the founders of The Canadian Masters Rowing Committee and he helped to initiate master's racing at the Canadian Henley. In 1985 he won the single, double and quad at the World Masters Regatta in Toronto. For a number of years he was also the world record holder for his age category on the C2 ergometer. His last heartfelt project was the construction of a wheelchair ramp at Resurrection Lutheran Church where he was an active member. Mr. Biernacki passed away on January 9, 1998 at the age of 66 after a valiant battle with cancer only a month after being awarded the Canadian Coaching Provincial Coaching Award. He is survived by his wife Janet, daughters Tracy, Tammy Pauls, and Tory Phannenhour, and son, Tony Jr. He is also survived by several grandchildren.

La Diplomacia del Jazz como una estrategia de política exterior de Estados Unidos durante la Guerra Fría

En aras de contener el comunismo y expandir la cultura norteamericana y los valores de democracia y libertad, Estados Unidos lanzó una estrategia de política exterior denominada la Diplomacia del Jazz, que consistía en promocionar internacionalmente el jazz mediante dos artificios: primero, la celebración de conciertos de los intérpretes más representativos de este género en diferentes partes del mundo; y segundo, la trasmisión de programas radiales sobre jazz en emisoras de difusión internacional y así poder mostrar la “superioridad” cultural de su país en detrimento de la otra superpotencia, la Unión Soviética. De este modo, la presente monografía tiene como fin estudiar de qué manera se instrumentalizó dicha estrategia como un medio para proyectar positivamente la imagen de los EEUU durante la Guerra Fría, concretamente entre 1954 y 1968, a partir de la teoría del realismo progresivo de Joseph Nye.

Relación entre los estilos de liderazgo y los niveles de resiliencia de los subordinados

El presente documento hace un análisis de la influencia que ejercen los diferentes tipos de liderazgo, carismático y transaccional, de un directivo de una organización sobre los subordinados de la misma, que a su vez afecta positiva o negativamente el nivel de resiliencia de los mismos. De la misma forma, se ha identificado la relación que existe entre el nivel de resiliencia de los subordinados de una organización y el cumplimiento de objetivos corporativos de la misma. Todo lo anterior se justifica en la economía globalizada de la que ahora hacemos parte que obliga a las empresas a generar nuevas estrategias de competitividad dentro de ambientes turbulentos y cambiantes donde, el desarrollar y motivar el recurso humano de la organización toma importancia para la ejecución exitosa de estrategias diferenciales.

Projeto, construção e análise de um prototipo vibracional em escala de bancada aplicável ao tratamento de água de produção de petróleo bruto, mediante inovadora operação híbrida de adsorção e auto-flotação

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

Modelagem e desenvolvimento de um banco de dados geográficos : aplicação à elaboração de mapas de sensibilidade ambiental ao derramamento de óleo na área costeira entre galinhos e São Bento do Norte-RN

The area between Galinhos and São Bento do Norte beaches, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings due to the Guamaré Petroliferous Pole nearby, the greater terrestrial oil producing in Brazil. Before all these characteristics had been organized MAMBMARE and MARPETRO projects with the main objective to execute the geo-environmental monitoring of coastal areas on the northern portion of RN. There is a bulky amount of database from the study area such as geologic and geophysical multitemporal data, hydrodynamic measurements, remote sensing multitemporal images, thematic maps, among others; it is of extreme importance to elaborate a Geographic Database (GD), one of the main components of a Geographic Information System (GIS), to store this amount of information, allowing the access to researchers and users. The first part of this work consisted to elaborate a GD to store the data of the area between Galinhos and São Bento do Norte cities. The main goal was to use the potentiality of the GIS as a tool to support decisions in the environmental monitoring of this region, a valuable target for oil exploration, salt companies and shrimp farms. The collected data was stored as a virtual library to assist men decisions from the results presented as digital thematic maps, tables and reports, useful as source of data in the preventive planning and as guidelines to the future research themes both on regional and local context. The second stage of this work consisted on elaborate the Oil-Spill Environmental Sensitivity Maps. These maps based on the Environmental Sensitivity Index Maps to Oil Spill developed by the Ministry of Environment are cartographic products that supply full information to the decision making, contingency planning and assessment in case of an oil spilling incident in any area. They represent the sensitivity of the areas related to oil spilling, through basic data such as geology, geomorphology, oceanographic, social-economic and biology. Some parameters, as hydrodynamic data, sampling data, coastal type, declivity of the beach face, types of resources in risk (biologic, economic, human or cultural) and the land use of the area are some of the essential information used on the environmental sensitivity maps elaboration. Thus using the available data were possible to develop sensitivity maps of the study area on different dates (June/2000 and December/2000) and to perceive that there was a difference on the sensitivity index generated. The area on December presented more sensible to the oil than the June one because hydrodynamic data (wave and tide energy) allowed a faster natural cleaning on June. The use of the GIS on sensitivity maps showed to be a powerful tool, since it was possible to manipulate geographic data with correctness and to elaborate more accurate maps with a higher level of detail to the study area. This presented an medium index (3 to 4) to the long shore and a high index (10) to the mangrove areas highly vulnerable to oil spill

Intraspecific variability in the basal metabolic rate: Testing the food habits hypothesis

Several competing hypotheses attempt to explain how environmental conditions affect mass-independent basal metabolic rate (BMR) in mammals. One of the most inclusive and yet debatable hypotheses is the one that associates BMR with food habits, including habitat productivity. These effects have been widely investigated at the interspecific level under the assumption that for any given species all traits are fixed. Consequently, the variation among individuals is largely ignored. Intraspecific analysis of physiological traits has the potential to compensate for many of the pitfalls associated with interspecific analyses and, thus, to be a useful approach for evaluating hypotheses regarding metabolic adaptation. In this study, we investigated the effects of food quality, availability, and predictability on the BMR of the leaf-eared mouse Phyllotis darwini. BMR was measured on freshly caught animals from the field, since they experience natural seasonal variations in environmental factors ( and, hence, variations in habitat productivity) and diet quality. BMR was significantly correlated with the proportion of dietary plants and seeds. In addition, BMR was significantly correlated with monthly habitat productivity. Path analysis indicated that, in our study, habitat productivity was responsible for the observed changes in BMR, while diet per se had no effect on this variable.

Effect of age on seed digestion in parrots (Amazona aestiva)

The objective of this study was to compare the capacity of adult (more than 3 yr old) and young (less than 1 yr old) true parrots to digest seeds that are normally included in their diet in captivity, particularly soybean, sunflower, and corn. All the seeds were offered for 5 d with an interval of 15 d between different diets. The seeds of soybean and corn were boiled for 15 min and soaked in water at ambient temperature for 12 h before being fed to the birds. There were no differences in the digestibilities of crude protein and fats (ether extract) among animals, but the digestibilities of dry matter and crude fiber by the adult animals were higher than those of the young ones. The digestibility of carbohydrate (nitrogen-free extract) by adult birds was higher only for sunflower seeds. It is concluded that the capacity of parrots to digest fiber may change according to the age of the animal. Since the digestion of fiber depends on the action of microorganisms, these results suggest that the colonization of the gastrointestinal tract is delayed or very slow in young parrots.

Reply to "Heart Position in Snakes"

In a previous paper comparing 155 species of snakes, we showed that the position of the heart relative to the head is statistically related to both habitat usage and phylogenetic position ("Phylogeny, ecology, and heart position in snakes," Physiological and Biochemical Zoology 83: 43-54). More specifically, we found that, on average, arboreal snakes in our study had hearts placed more posteriorly than terrestrial species (P<0.0001). In their response, Professors Lillywhite and Seymour express the concerns that readers " might be misled by this statement or conclude that gravity has no clear influence on heart position in snakes." We do not share these concerns, and we respond to all of the issues raised in their commentary. We look forward to new data on the positions of snake hearts and further analyses that seek to test adaptive hypotheses by rigorous phylogenetic approaches.
