Oats

The past season had a most unfavorable influence upon the oat crop of the state. The scarcity of suitable seed oats is very forcibly brought to the attention when we consider that there is not enough of the 1907 crop of standard weight (32 lbs. per bu.) to sow the fields that will go into oats this spring. The oats are extremely light, being from 30 to 50 per cent hull, and average from 16 to 25 pounds per bushel. There are comparatively few exceptions where they weigh more than the maximum given

Bright Source Subtraction Requirements For Redshifted 21 cm Measurements

The \hi 21 cm transition line is expected to be an important probe into the cosmic dark ages and epoch of reionization. Foreground source removal is one of the principal challenges for the detection of this signal. This paper investigates the extragalactic point source contamination and how accurately bright sources ($\gtrsim 1$ ~Jy) must be removed in order to detect 21 cm emission with upcoming radio telescopes such as the Murchison Widefield Array (MWA). We consider the residual contamination in 21 cm maps and power spectra due to position errors in the sky-model for bright sources, as well as frequency independent calibration errors. We find that a source position accuracy of 0.1 arcsec will suffice for detection of the \hi power spectrum. For calibration errors, 0.05 % accuracy in antenna gain amplitude is required in order to detect the cosmic signal. Both sources of subtraction error produce residuals that are localized to small angular scales, \kperp \gtrsim 0.05 Mpc$^{-1}$, in the two-dimensional power spectrum.Comment: 12 pages, 19 Figures, submitted to Ap

The critical elements of effective academic-practice partnerships: a framework derived from the Department of Veterans Affairs Nursing Academy.

BackgroundThe nursing profession is exploring how academic-practice partnerships should be structured to maximize the potential benefits for each partner. As part of an evaluation of the U.S. Department of Veterans Affairs Nursing Academy (VANA) program, we sought to identify indicators of successful partnerships during the crucial first year.MethodsWe conducted a qualitative analysis of 142 individual interviews and 23 focus groups with stakeholders from 15 partnerships across the nation. Interview respondents typically included the nursing school Dean, the VA chief nurse, both VANA Program Directors (VA-based and nursing school-based), and select VANA faculty members. The focus groups included a total of 222 VANA students and the nursing unit managers and staff from units where VANA students were placed. An ethnographic approach was utilized to identify emergent themes from these data that underscored indicators of and influences on Launch Year achievement.ResultsWe emphasize five key themes: the criticality of inter-organizational collaboration; challenges arising from blending different cultures; challenges associated with recruiting nurses to take on faculty roles; the importance of structuring the partnership to promote evidence-based practice and simulation-based learning in the clinical setting; and recognizing that stable relationships must be based on long-term commitments rather than short-term changes in the demand for nursing care.ConclusionsDeveloping an academic-clinical partnership requires identifying how organizations with different leadership and management structures, different responsibilities, goals and priorities, different cultures, and different financial models and accountability systems can bridge these differences to develop joint programs integrating activities across the organizations. The experience of the VANA sites in implementing academic-clinical partnerships provides a broad set of experiences from which to learn about how such partnerships can be effectively implemented, the barriers and challenges that will be encountered, and strategies and factors to overcome challenges and build an effective, sustainable partnership. This framework provides actionable guidelines for structuring and implementing effective academic-practice partnerships that support undergraduate nursing education

A randomized trial of brief intervention strategies in patients with alcohol-related facial trauma as a result of interpersonal violence

Facial trauma is associated with male gender, low socioeconomic status, alcohol misuse, and violence. Brief intervention (BI) for alcohol is effective at reducing consumption in patients presenting with facial trauma. Singlesession control of violence for angry impulsive drinkers(SS-COVAID) is a new intervention that attempts to address alcohol-related violence. This study assessed the effect of SS-COVAID and BI on drinking and aggression in facial trauma patients. Male facial trauma patients who sustained their injuries as a result of interpersonal violence while drinking and who had Alcohol Use Disorders Identification Test (AUDIT) scores of ≥8 were randomized to either BI or SS-COVAID. Patients were followed up at six and 12 months, and drinking and aggression outcomes were analyzed. One hundred ninety-nine patients entered the trial, and 187 were included in the analysis. Of these, 165 (89%) considered themselves to be victims, 92 (51%) had sustained a previous alcohol-related injury, and 28 (15%) had previous convictions for violence. Both interventions resulted in a significant decrease in negative drinking outcomes over 12 months of follow-up (p<0.001). Neither intervention had a significant effect on aggression scores, nor was there a significant difference between interventions in terms of either outcome. Both SS-COVAID and BI had a significant effect on drinking variables in this patient cohort. No effect on aggressionwas seen despite the fact that SS-COVAID specifically addresses the relationship between alcohol and violence. One reason for this may be that the facial trauma patients in this study considered themselves to be victims rather than aggressors. Another possibility is that, while BI may successfully address lifestyle factors such as hazardous or harmful drinking, it may not be effective in modifying personality traits such as aggression

Structural characterization of Si(m)Ge(n) strained layer superlattices

SimGen strained layer superlattice (SLS) structures were grown by molecular beam epitaxy on GexSi1-x buffer layers on Si substrates to determine the effects of buffer layer composition, SLS thickness ratio, and superlattice periodicity, on the overall quality of these structures. X-ray diffraction methods were used to determine how closely actual periodicities and compositions met targeted values, and to evaluate the quality of these samples. In most instances the as-grown structures matched the targeted values to within 10%, though in some instances deviations of 20-25% in either the period or composition were observed. The quality of the SLS structures was greatly dependent on the composition of the buffer layer on which it was grown. SimGen SLS structures grown on Si- and Ge-rich buffer layers were of much higher quality than SimGem SLSs grown on Ge0.50Si0.50 layers, but the x-ray rocking curves of the SimGen samples indicated that they were far from perfect and contained moderate levels of defects. These results were confirmed by cross sectional transmission electron microscopy, which showed that the SimGem structures contained significant numbers of dislocations and that the layers were nonuniform in thickness and wavy in appearance. SimGen structures, however, displayed fewer defects but some dislocations and nonparallelism of layers were still observed

Proton NMR studies of the electronic structure of ZrH/sub x/

The proton spin lattice relaxation times and Knight shifts were measured in f.c.c. (delta-phase) and f.c.t. (epsilon-phase) ZrH/sub x/ for 1.5 or = to x or = to 2.0. Both parameters indicate that N(E/sub F/) is very dependent upon hydrogen content with a maximum occurring at ZrH1 83. This behavior is ascribed to modifications in N(E/sub F/) through a fcc/fct distortion in ZrH/sub x/ associated with a Jahn-Teller effect
