Webinar to Address Flood Recovery for Cropland

As waters recede from farmland that has been covered for several months by Missouri River flooding, Iowa State University (ISU) Extension and Outreach and the University of Nebraska-Lincoln (UNL) Extension are jointly planning a workshop for Monday, Sept. 12 to address cropland issues. The workshop will be conducted via webinar at several viewing sites in both states from 9:30 a.m. to noon. Extension agriculture staff will host the workshop sites and facilitate questions to the panel

Rules of thumb for deselecting, relocating, and retaining bound journals

Purpose – Like many other academic libraries, Joyner Library at East Carolina University has experienced pressure in recent years to convert stacks space to other uses. The rise of electronic collections coupled with the changing perception of libraries from book warehouses to service points forces librarians to rethink their collection management strategies, concomitantly reducing print collections. The purpose of this article is to recommend specific strategies that will assist librarians engaged in a large-scale deselection project. Design/methodology/approach – First, librarians, staff, and graduate assistants developed a workflow to examine print journals for which the library has online archival holdings in order to de-duplicate the collection. Librarians also determined which titles might be stored based on some online availability and length of print run. Third, librarians led a subject-based review to determine which titles should be retained in the general circulating collections. Findings – Examination proved that most online journals archives, including publisher packages, are adequate replacements for print serials volumes. Many other journal titles can safely be sent to storage rather than retained in the general circulating collections. Practical implications – Libraries must manage their print collections differently in light of space issues and the conversion of scholarship from print to electronic format. Originality/value – This article establishes clear principles to guide libraries' decisions on deselecting, storing, and retaining print serials volumes

Inventory: catalyst for collection development

Purpose : The intent of this article is to show the direct outcomes of an inventory project, which served as the catalyst for collection development improvements. Design/methodology/approach : An inventory project was undertaken with a major emphasis on the outcomes derived from the inventory. Findings : Several types of problems were discovered, such as missing items, incorrect information (call numbers, collection codes, item types, etc.), damaged materials, and weaknesses in the collection, which resulted in major improvements and changes in the development of the collection. Originality/value : The results of the inventory project improved the accessibility of the collection to patrons by correcting many inconsistencies involving the shelving of materials, online records, call numbers, collection codes, item types, and bar codes. The location of missing items as well as identified areas of strengths and weaknesses assisted with collection development activities. The results of the project also provided an opportunity to hire a consulting firm to further assess the collection, which led to additional funds for supporting the collection. The single major benefit of the inventory process was that it provided the catalyst for instigating major changes in the curriculum collection development of the Teaching Resources Center

Foreign occupation and the development of Filipino nationalism

Title from PDF of title page (University of Missouri--Columbia, viewed on April 1, 2011).The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Thesis advisor: Dr. Robert Smale.M.A. University of Missouri--Columbia 2010.The history of the Philippines is one defined by its regional, ethnic and geographical division. Since its settlement by the earliest Malay immigrants, the over 7,000 islands have hosted a multitude of cultures, languages, religions and societies. Despite this diversity, a strong nationalist movement emerged in the late 1800s, and developed into a unified Filipino identity by the end of World War II. This study seeks to understand how a region so historically divided could adopt a single national identity. Examination of the Philippines' three major occupations suggests that the crucial factor that enabled nationalism to take root was colonialism. Over the course of 400 years, Spain, the U.S. and Japan incorporated these isolated cultures under one rule. As a result, the disparate groups developed a common history out of a shared experience of colonial exploitation. Foreign powers imposed many foundational changes in the Philippines, both intentional and unintentional. In particular, colonization introduced new aspects of cross-regional unity (Catholicism, a lingua franca, etc.) while also strengthening existing historical commonalities, such as "Filipino values" and paternalism. As colonial offenses grew, Filipino resistance intensified, uniting Filipinos against a common enemy. Over the decades, these alliances of necessity became permanent parts of cultural identity, culminating in the popular anti-Japanese resistance armies of World War II, who organized extensive guerrilla armies independent of elite control.Includes bibliographical reference

Aviation Fueling: A Cleaner, Greener Approach

Projected growth of aviation depends on fueling where specific needs must be met. Safety is paramount, and along with political, social, environmental and legacy transport systems requirements, alternate aviation fueling becomes an opportunity of enormous proportions. Biofuels sourced from halophytes, algae, cyanobacteria, and weeds using wastelands, waste water, and seawater have the capacity to be drop-in fuel replacements for petroleum fuels. Biojet fuels from such sources solves the aviation CO2 emissions issue and do not compete with food or freshwater needs. They are not detrimental to the social or environmental fabric and use the existing fuels infrastructure. Cost and sustainable supply remains the major impediments to alternate fuels. Halophytes are the near-term solution to biomass/biofuels capacity at reasonable costs; they simply involve more farming, at usual farming costs. Biofuels represent a win-win approach, proffering as they do at least the ones we are studying massive capacity, climate neutral-to-some sequestration, and ultimately, reasonable costs

Feasibility of Bedded Hoop Barns for Market Beef Cattle in Iowa: Cattle Performance, Bedding Use, and Environment

The objective was to document a bedded hoop barn for feeding market beef cattle. A comparison between a bedded hoop barn (15.2 × 36.6 m) and an open-front feedlot building (11.0 × 61.0 m) was conducted in southwest Iowa. The hoop barn was oriented north-south on a ridge with no windbreak. In summer, temperature was relatively consistent between the structures and ambient conditions, although the north end of the hoop barn had a slightly elevated dew point temperature. A summer temperature-humidity index showed that the hoop barn had fewer hours in alert category than either open front or ambient conditions. In winter, a cold stress index showed that the open-front barn provided the most shelter for the cattle with 92% of the hours classified as no impact, compared with the hoop barn at 77% and ambient at 51%. Both ends of the hoop barn were open, except for piled big round bales for a windbreak during winter. Growth, feed-to-gain, and dry matter intake for the cattle were similar between housing systems. Quality and yield grades were similar. Mud scores may be less for cattle from the bedded hoop barn compared with the open-front feedlot where mud was possible. Labor usage was similar for the hoop barn and the open-front feedlot. Labor occurred throughout the feeding period for the hoop barn because manure cleaning occurred weekly. Bedded hoop barns offer a viable alternative for feeding beef cattle and may reduce feedlot runoff

Computational Analysis of Dynamic SPK(S8)-JP8 Fueled Combustor-Sector Performance

Civil and military flight tests using blends of synthetic and biomass fueling with jet fuel up to 50:50 are currently considered as "drop-in" fuels. They are fully compatible with aircraft performance, emissions and fueling systems, yet the design and operations of such fueling systems and combustors must be capable of running fuels from a range of feedstock sources. This paper provides Smart Combustor or Fuel Flexible Combustor designers with computational tools, preliminary performance, emissions and particulates combustor sector data. The baseline fuel is kerosene-JP-8+100 (military) or Jet A (civil). Results for synthetic paraffinic kerosene (SPK) fuel blends show little change with respect to baseline performance, yet do show lower emissions. The evolution of a validated combustor design procedure is fundamental to the development of dynamic fueling of combustor systems for gas turbine engines that comply with multiple feedstock sources satisfying both new and legacy systems
