Comparison of multiple post-emergence Callisto applications for spreading dogbane (\u3cem\u3eApocynum androsaemifolium\u3c/em\u3e L.) control in wild blueberry fields
Spreading dogbane (Apocynum androsaemifolium L.) is a major weed pest in wild blueberry (Vaccinium angustifolium Ait.) fields and is difficult to control. In a 2016 trial conducted in a prune year wild blueberry field, spreading dogbane was sprayed post-emergence with mesotrione (Callisto) at 146 mL/ha or 219 mL/ha product per application to 1 x 4 m split plots, with one half also receiving pre-emergence hexazinone (Velpar). Dogbane emergence and growth were monitored, and plots were sprayed when dogbane reached the 3-5 leaf stage and again after regrowth for a total of three Callisto applications for each rate. Although both Callisto-Velpar combinations (93% control in July) and Callisto 219 mL/ha alone (98% control in July) almost eliminated dogbane, and no new seedlings were observed at the fourth evaluation in July, dogbane was not completely controlled by any treatment. Some of the dogbane stems which appeared dead at the third evaluation in June showed regrowth of lateral leaves in July. T-tests comparing Velpar vs no Velpar indicated that the addition of Velpar slightly increased dogbane control and injury, but the effects were not significant at α=0.05. The commercial landowner’s adjacent treatment of a split Callisto application followed by a mid-summer glyphosate wiper application exhibited better long-term control of dogbane, and warrants further investigation

Fiber-Matrix Interface Studies on Electron Beam Cured Composites
The recently completed Department of Energy (DOE) and industry sponsored Cooperative Research and Development Agreement (CRADA) entitled, ''Electron Beam Curing of Polymer Matrix Composites,'' determined that the interlaminar shear strength properties of the best electron beam cured IM7/epoxy composites were 19-28% lower than autoclave cured IM7/epoxy composites (i.e. IM7/977-2 and IM7/977-3). Low interlaminar shear strength is widely acknowledged as the key barrier to the successful acceptance and implementation of electron beam cured composites in the aircraft/aerospace industry. The objective of this work was to improve the interlaminar shear strength properties of electron beam cured composites by formulating and evaluating several different fiber sizings or coating materials. The researchers have recently achieved some promising results by having discovered that the application of epoxy-based, electron beam compatible sizings or coatings onto surface-treated, unsized IM7 carbon fibers improved the composite interlaminar shear strength properties by as much as 55% versus composites fabricated from surface-treated, unsized IM7 fibers. In addition, by applying these same epoxy-based sizings or coatings onto surface-treated, unsized IM7 fibers it was possible to achieve an 11% increase in the composite interlaminar shear strength compared to composites made from surface-treated, GP-sized IM7 fibers. Work is continuing in this area of research to further improve these properties

The acute-to-chronic workload ratio:An inaccurate scaling index for an unnecessary normalisation process?
BACKGROUND: Problematic use of alcohol and other drugs (AOD) is highly prevalent among people living with the human immunodeficiency virus (PLWH), and untreated AOD use disorders have particularly detrimental effects on human immunodeficiency virus (HIV) outcomes. The Healthcare Effectiveness Data and Information Set (HEDIS) measures of treatment initiation and engagement are important benchmarks for access to AOD use disorder treatment. To inform improved patient care, we compared HEDIS measures of AOD use disorder treatment initiation and engagement and health care utilization among PLWH and patients without an HIV diagnosis.
METHODS: Patients with a new AOD use disorder diagnosis documented between October 1, 2014, and August 15, 2015, were identified using electronic health records (EHR) and insurance claims data from 7 health care systems in the United States. Demographic characteristics, clinical diagnoses, and health care utilization data were also obtained. AOD use disorder treatment initiation and engagement rates were calculated using HEDIS measure criteria. Factors associated with treatment initiation and engagement were examined using multivariable logistic regression models.
RESULTS: There were 469 PLWH (93% male) and 86,096 patients without an HIV diagnosis (60% male) in the study cohort. AOD use disorder treatment initiation was similar in PLWH and patients without an HIV diagnosis (10% vs. 11%, respectively). Among those who initiated treatment, few engaged in treatment in both groups (9% PLWH vs. 12% patients without an HIV diagnosis). In multivariable analysis, HIV status was not significantly associated with either AOD use disorder treatment initiation or engagement.
CONCLUSIONS: AOD use disorder treatment initiation and engagement rates were low in both PLWH and patients without an HIV diagnosis. Future studies need to focus on developing strategies to efficiently integrate AOD use disorder treatment with medical care for HIV
