Durum wheat quality I: some physical and chemical characteristics of Syrian durum wheat genotypes
Ultra-Efficient Engine Technology (UEET) Program
The Ultra-Efficient Engine Technology (UEET) Program includes seven key projects that work with industry to develop and hand off revolutionary propulsion technologies that will enable future-generation vehicles over a wide range of flight speeds. A new program office, the Ultra-Efficient Engine Technology (UEET) Program Office, was formed at the NASA Glenn Research Center to manage an important National propulsion program for NASA. The Glenn-managed UEET Program, which began on October 1, 1999, includes participation from three other NASA centers (Ames, Goddard, and Langley), as well as five engine companies (GE Aircraft Engines, Pratt & Whitney, Honeywell, Allison/Rolls Royce, and Williams International) and two airplane manufacturers (the Boeing Company and Lockheed Martin Corporation). This 6-year, nearly $300 million program will address local air-quality concerns by developing technologies to significantly reduce nitrogen oxide (NOx) emissions. In addition, it will provide critical propulsion technologies to dramatically increase performance as measured in fuel burn reduction that will enable reductions of carbon dioxide (CO2) emissions. This is necessary to address the potential climate impact of long-term aviation growth
Improved Answer-Set Programming Encodings for Abstract Argumentation
The design of efficient solutions for abstract argumentation problems is a
crucial step towards advanced argumentation systems. One of the most prominent
approaches in the literature is to use Answer-Set Programming (ASP) for this
endeavor. In this paper, we present new encodings for three prominent
argumentation semantics using the concept of conditional literals in
disjunctions as provided by the ASP-system clingo. Our new encodings are not
only more succinct than previous versions, but also outperform them on standard
benchmarks.Comment: To appear in Theory and Practice of Logic Programming (TPLP),

Public Process and Ohio Supreme Court Rulemaking
While court created rules, in terms of their impact on society, are often as important as judicial decisions or legislative acts, they are relatively unknown to the general public. Further, there is often no public input prior to their adoption. Rather, court rules are often promulgated with no opportunity for general public discussion. Judge Jack B. Weinstein recently called attention to such a lack of public process in federal court rulemaking and expressed the hope that others will speak out so that the matter can be thoroughly debated. On the state level this factor is absent from most rulemaking promulgated by the Ohio Supreme Court, and this article will speak out on the need for injecting public process into the exercise of judicial rulemaking authority by that body

Who receives treatment for alcohol use disorders in the European Union? A cross-sectional representative study in primary and specialized health care
Background
Alcohol use disorders (AUDs) are highly prevalent in Europe, but only a minority of those affected receive treatment. It is therefore important to identify factors that predict treatment in order to reframe strategies aimed at improving treatment rates.
Methods
Representative cross-sectional study with patients aged 18\u201364 from primary health care (PC, six European countries, n = 8476, data collection 01/13\u201301/14) and from specialized health care (SC, eight European countries, n = 1762, data collection 01/13\u201303/14). For descriptive purposes, six groups were distinguished, based on type of DSM-IV AUD and treatment setting. Treatment status (yes/no) for any treatment (model 1), and for SC treatment (model 2) were main outcome measures in logistic regression models.
Results
AUDs were prevalent in PC (12-month prevalence: 11.8%, 95% confidence interval (CI): 11.2\u201312.5%), with 17.6% receiving current treatment (95%CI: 15.3\u201319.9%). There were clear differences between the six groups regarding key variables from all five predictor domains. Prediction of any treatment (model 1) or SC treatment (model 2) was successful with high overall accuracy (both models: 95%), sufficient sensitivity (model 1: 79%/model 2: 76%) and high specificity (both models: 98%). The most predictive single variables were daily drinking level, anxiety, severity of mental distress, and number of inpatient nights during the last 6 months.
Conclusions
Variables from four domains were highly predictive in identifying treatment for AUD, with SC treatment groups showing very high levels of social disintegration, drinking, comorbidity and functional losses. Earlier intervention and formal treatment for AUD in PC should be implemented to reduce these high levels of adverse outcomes
Phenolics, flavonoids and antioxidant capacities in Citrus species with different degree of tolerance to Huanglongbing
Huanglongbing (HLB) is a highly destructive disease to the citrus industry in Florida caused by the
bacterium, Candidatus Liberibacter asiaticus(CLas) and is transmitted by Diaphorina citri. It is hypothesized
that plants with high phenolic contents show higher tolerance to certain plant pathogens. In this
regard, different citrus varieties and plants of genera related to Citrus were analyzed for their total
phenolic and flavonoids contents, and their antioxidant capacities. In addition, the secondary metabolites
in the leaves of seven citrus species were analyzed using high performance liquid chromatographymass
spectrometry (HPLC-MS). Colorimetric assays showed that curry leaf contained the highest total
phenolic content and free radical scavenging activity (DPPH). Curry leaf also contained high concentrations
of an unusual class of carbazole alkaloids. Tolerant Citrus species contained high levels of phenolics
and flavonoids and showed high antioxidant capacities. Our results suggest that high phenolic and
flavonoid leaf contents correlate with increased citrus tolerance to CLas bacterium. The results also
suggest that the high level of carbazole alkaloids, known for their strong antimicrobial properties in
curry leaf, could make it immune to the CLas bacteria. Understanding the mechanisms underpinning
citrus tolerance to HLB will contribute to the development of commercially tolerant citrus cultivars.Acknowledgments
