A pressing challenge facing the aviation industry is to aggressively reduce greenhouse gas emissions in the face of increasing demand for aviation fuels. Climate goals such as carbon-neutral growth from 2020 onwards require continuous improvements in technology, operations, infrastructure, and most importantly, reductions in aviation fuel life cycle emissions. The Carbon Offsetting Scheme for International Aviation of the International Civil Aviation Organization provides a global market-based measure to group all possible emissions reduction measures into a joint program.

When species have multiple modes of reproduction, the prevalence of different modes can influence management decisions. We used genetic markers to determine the prevalent method of recruitment for invasive Russian knapweed ().

The workshop's objectives were to: (i) provide training in the methods, design, and conduct of clinical trials; (ii) ensure that clinical trials met federal and international ethical guidelines; (iii) evaluate the effectiveness of the workshop; and (iv) create networking opportunities for young investigators with mentoring senior faculty. Educational methods included: (i) didactic lectures, (ii) Small Group Discussion Sessions, (iii) Protocol Development Groups, and (iv) one-on-one mentoring.
View Article and Find Full Text PDFA classical biological control agent is an exotic host-specific natural enemy, which is intentionally introduced to obtain long-term control of an alien invasive species. Among the arthropods considered for this role, eriophyid mites are likely to possess the main attributes required: host specificity, efficacy, and long-lasting effects. However, so far, only a few species have been approved for release.

For each basin, six discrete liquid-unloading scenarios are considered, consisting of combinations of well types (conventional and unconventional) and liquid-unloading systems (nonplunger, manual plunger lift, and automatic plunger lift). Analysis reveals that methane emissions from liquids unloading are highly variable, with mean TNMEs ranging from 0.

One aspect which is still unclear is whether releases of multiple, genetically distinct populations of a biological control agent increase the likelihood of success, either by independent colonization of different environmental niches or by hybridization that may increase the agent's fitness and adaptive ability. Since hybridization is often invoked to explain the success of unintentionally introduced exotic species, hybridization among biocontrol agents may be similarly important in shaping the effectiveness of biological control programs.

Case Report: We describe a case of recurrent bacterial cystitis caused by Escherichia coli (E.
Introduction: Cannabis is the most common illegal substance used in the world. The psychoactive nature of cannabis is primarily due to delta-9-tetrahydrocannabinol (THC). Some research suggests that prolonged cannabinoid use increases its half-life and fat solubility in the body, slowing gastric emptying, leading towards feelings of nausea and vomiting.

A detailed gate-to-gate LCA model of EOR was developed and incorporated into a cradle-to-grave boundary with a functional unit of 1 MJ of combusted gasoline. The cradle-to-grave model includes two sources of CO2: natural domes and anthropogenic (fossil power equipped with carbon capture).

Method: 76 MS from four clerkship blocks participated. Blocks one and three (Treatment group) were provided case materials containing the patient's name and facial picture while blocks two and four (Control group) were provided similar materials without the patient's name or image.
Academic dentistry, as a career track, is not attracting sufficient numbers of new recruits to maintain a corps of skilled dental educators. The Faculty Development Program (FDP) at the University of Texas Health Science Center at San Antonio Dental School received federal funds to institute a 7-component program to enhance faculty recruitment and retention and provide training in skills associated with success in academics including:(1) a Teaching Excellence and Academic Skills (TExAS)Fellowship, (2) training in research methodology,evidence-based practice research, and information management, (3) an annual dental hygiene faculty development workshop for dental hygiene faculty, (4) a Teaching Honors Program and Academic Dental Careers Fellowship to cultivate students' interest in educational careers, (5) an Interprofessional Primary Care Rotation,(6) advanced education support toward a master's degree in public health, and (7) a key focus of the entire FDP, an annual Career Transition Workshop to facilitate movement from the practice arena to the educational arm of the profession.The Career Transition Workshop is a cap stone for the FDP; its goal is to build a bridge from practice to academic environment.

This study used generalizability theory to assess changes in score reliability when the number of questions per case varied in the National Board Dental Hygiene Examination (NBDHE). The experimental design maintained the same total number of case-based items, while varying the number of cases and items within cases to assess changes in score reliability.
View Article and Find Full Text PDFBeginning in 2012, candidate performance on the National Board Dental Examination (NBDE) has been reported as pass/fail, and only the failing candidates receive numerical scores for remediation purposes. The Joint Commission on National Dental Examinations recognizes that the numerical scores have been important information to dental schools for curriculum evaluation and that the pass/fail reports do not provide meaningful information to the schools. This article describes the process of evaluating and validating a new model for reporting standardized school-level performance data on the NBDE.

In this study, numerical course scores of second-year dental students in four successive classes in an oral and maxillofacial pathology course were compared. While the course content and teaching methods were essentially unchanged throughout the four years, two modest departures from the sole use of multiple-choice format questions were made in the assessment of student achievements. The modifications consisted of creating a more challenging examination procedure through the inclusion of un-cued short-answer format questions and the institution of correction-for-guessing scoring on multiple-choice examinations.
