perceived need for treatment among pregnant and nonpregnant women arrestees.previous research has noted a high rate of drug use by women arrestees. not only are women arrestees more likely to be found drug positive by urinalysis than are men arrestees, but in recent years, in part because of drug use, women have constituted the fastest growing population segment involved with the criminal justice system. one small but important subgroup of women arrestees are those who are pregnant and, thus, who particularly need intervention. this article utilizes drug use forecasting ...20078788694

mitigation of pah and nitro-pah emissions from nonroad diesel engines.more stringent emission requirements for nonroad diesel engines introduced with u.s. tier 4 final and euro stage iv and v regulations have spurred the development of exhaust aftertreatment technologies. in this study, several aftertreatment configurations consisting of diesel oxidation catalysts (doc), diesel particulate filters (dpf), cu zeolite-, and vanadium-based selective catalytic reduction (scr) catalysts, and ammonia oxidation (amox) catalysts are evaluated using both nonroad transient ( ...201525668360
eu effect: exporting emission standards for vehicles through the global market economy.emission data from edgar (emissions database for global atmospheric research), rather than economic data, are used to estimate the effect of policies and of the global exports of policy-regulated goods, such as vehicles, on global emissions. the results clearly show that the adoption of emission standards for the road transport sector in the two main global markets (europe and north america) has led to the global proliferation of emission-regulated vehicles through exports, regardless the domest ...201627681872
pacific salmon extinctions: quantifying lost and remaining diversity.widespread population extirpations and the consequent loss of ecological, genetic, and life-history diversity can lead to extinction of evolutionarily significant units (esus) and species. we attempted to systematically enumerate extinct pacific salmon populations and characterize lost ecological, life history, and genetic diversity types among six species of pacific salmon (chinook [oncorhynchus tshawytscha], sockeye [o. nerka], coho [o. kisutch], chum [o. keta], and pink salmon [o. gorbuscha] ...200717650251
