State Legislation Monitoring Report FY2004, February 2005

The Division of Criminal and Juvenile Justice Planning issued its first state legislation monitoring report in February 2002, covering the first six months’ impact of Senate File 543 (which enacted a number of sentencing changes) on the justice system; monitoring of the correctional impact of this bill was at the request of several members of the legislature. Since then, the Criminal and Juvenile Justice Planning Advisory Council has requested that CJJP monitor the correctional impact of enacted legislation of particular interest. This report covers monitoring results or future plans to monitor the following: 1. Changes in “crack” cocaine and “powder” cocaine penalties under Chapter 124.401 (effective FY2004; see p.3). 2. Commitments to prison involving manufacture, distribution, or possession of methamphetamine under Chapter 124.401 (see p.5). 3. Prosecution of offenders for child endangerment under Chapter 726.6(g) for permitting the presence of a child or minor at a location where a controlled substance manufacturing or a product possession violation occurs (see p.7). 4. Provision of an enhanced penalty for manufacturing of controlled substances under Chapter 124.401C when children are present and the offender is not charged under section 726.6(g) (see p. 7). 5. Creating a new offense when a retailer sells more than two packages of any product containing pseudoephedrine (chapter 126.23A) and providing for an enhanced penalty under Chapter 714.7C when a theft involves more than two packages of similar products (see p.8). 6. Establishment of parole eligibility at 70% of time served for persons sentenced under the “85% law” provisions of Iowa Code Section 902.12. (effective FY2005; see p. 9).

Universal Design for Better Living The Essential Bathroom, May 2004

An easy-living home requires a full-sized bathroom on the main level. Family members will appreciate the extra space and guests of all ages and abilities will feel more welcome. At a minimum, you’ll need a five foot circle of open floor space for maneuvering a wheelchair between bathroom fixtures. A small powder room won’t work for guests who use walkers or wheelchairs. A shower stall—with no curb to step over—is more convenient than a tub for most guests. Make sure the doorway opening for the bathroom is at least 32 inches wide (preferably 36 inches). Universal design features, such as these, make homes better for everyone.

Biofuel Co-Product Uses for Pavement Geo-Materials Stabilization, TR-582, 2010

The production and use of biofuels has increased in the present context of sustainable development. Biofuel production from plant biomass produces not only biofuel or ethanol but also co-products containing lignin, modified lignin, and lignin derivatives. This research investigated the utilization of lignin-containing biofuel co-products (BCPs) in pavement soil stabilization as a new application area. Laboratory tests were conducted to evaluate the performance and the moisture susceptibility of two types of BCP-treated soil samples compared to the performance of untreated and traditional stabilizer-treated (fly ash) soil samples. The two types of BCPs investigated were (1) a liquid type with higher lignin content (co-product A) and (b) a powder type with lower lignin content (co-product B). Various additive combinations (co-product A and fly ash, co-products A and B, etc.) were also evaluated as alternatives to stand-alone co-products. Test results indicate that BCPs are effective in stabilizing the Iowa Class 10 soil classified as CL or A-6(8) and have excellent resistance to moisture degradation. Strengths and moisture resistance in comparison to traditional additives (fly ash) could be obtained through the use of combined additives (co-product A + fly ash; co-product A + co-product B). Utilizing BCPs as a soil stabilizer appears to be one of the many viable answers to the profitability of the bio-based products and the bioenergy business. Future research is needed to evaluate the freeze-thaw durability and for resilient modulus characterization of BCP-modified layers for a variety of pavement subgrade and base soil types. In addition, the long-term performance of these BCPs should be evaluated under actual field conditions and traffic loadings. Innovative uses of BCP in pavement-related applications could not only provide additional revenue streams to improve the economics of biorefineries, but could also serve to establish green road infrastructures.
