Feasibility of low energy radiative capture experiments at the LUNA underground accelerator facility

The LUNA (Laboratory Underground for Nuclear Astrophysics) facility has been designed to study nuclear reactions of astrophysical interest. It is located deep underground in the Gran Sasso National Laboratory, Italy. Two electrostatic accelerators, with 50 and 400 kV maximum voltage, in combination with solid and gas target setups allowed to measure the total cross sections of the radiative capture reactions $^2$H(p,$\gamma$)3He and $^{14}$N(p,$\gamma$)$^{15}$O within their relevant Gamow peaks. We report on the gamma background in the Gran Sasso laboratory measured by germanium and bismuth germanate detectors, with and without an incident proton beam. A method to localize the sources of beam induced background using the Doppler shift of emitted gamma rays is presented. The feasibility of radiative capture studies at energies of astrophysical interest is discussed for several experimental scenarios.Comment: Submitted to Eur. Phys. J.

Scaling Up

Moments of crisis require big, bold ideas. In this chapter we will zoom out of our close examination of the Northern Manhattan Community Voices Collaborative experience to propose ways to scale up the things that worked for us in order to make them applicable at a national level. With this chapter we honor the intent of the W. K. Kellogg Foundation in its support of learning laboratories across the nation. Our goal is to contribute to the collective dialogue on how to improve the health care system. Specifically, we propose that making a healthier nation and reducing health care costs will require more than simply moving toward universal health coverage — which is essential — or implementing technologies to digitalize medical records — which is useful. As epidemiologists would say, those things are necessary but not sufficient to overhaul our ailing health care system. Instead, we propose to reduce health care costs and improve health care access by implementing a national prevention program through collaboration based on a new health compact with society — one that delivers on the promise of justice for all and (paraphrasing our forefathers/mothers) the pursuit of health

New insights on final Epigravettian funerary behavior at Arene Candide cave (Western Liguria, Italy)

We gained new insights on Epigravettian funerary behavior at the Arene Candide cave through the osteological and spatial analysis of the burials and human bone accumulations found in the cave during past excavations. Archaeothanathological information on the human skeletal remains was recovered from diaries, field pictures and notes, and data from recent excavations was integrated. The secondary deposits have traditionally been interpreted as older burials that were disturbed to make space for new inhumations. Our results suggest that those disturbances were not casual: older burials were intentionally displaced to bury younger inhumations. Subsequently, some skeletal elements, especially crania, were arranged around the new burial; these were often placed within stone niches. Based on the composition of some clusters, which contain the bones of two individuals displaced together, it is possible that a double burial composed of two adults was originally present at the site. This would be a burial type that had not been recognized at Arene Candide until now. Strikingly, this potential double burial contained an individual showing pathological bowing of the limbs, a finding which is not infrequent in skeletons from Gravettian and Epigravettian multiple burials. In addition, the crania and other skeletal elements derived from this burial were intentionally placed around a new inhumation, whose skeleton possibly shows a milder form of the same disease (possibly hereditary rickets). This and other observations suggest that the five individuals belonging to the second phase of this “cemetery” (AMS dates spanning 12,030 – 11,180 cal BP) might have been buried over a relatively brief time span. Our study demonstrated similar behaviors in the first phase of mortuary use of the cave (12,820 – 12,420 cal BP), indicating a remarkable persistence in Final Epigravettian funerary models despite their archaeologically apparent rarity and intermittent nature

First measurement of the 14N(p,gamma)15O cross section down to 70 keV

In stars with temperatures above 20*10^6 K, hydrogen burning is dominated by the CNO cycle. Its rate is determined by the slowest process, the 14N(p,gamma)15O reaction. Deep underground in Italy's Gran Sasso laboratory, at the LUNA 400 kV accelerator, the cross section of this reaction has been measured at energies much lower than ever achieved before. Using a windowless gas target and a 4pi BGO summing detector, direct cross section data has been obtained down to 70 keV, reaching a value of 0.24 picobarn. The Gamow peak has been covered by experimental data for several scenarios of stable and explosive hydrogen burning. In addition, the strength of the 259 keV resonance has been remeasured. The thermonuclear reaction rate has been calculated for temperatures 90 - 300 *10^6 K, for the first time with negligible impact from extrapolations

U.S. State‐Supported Dental Schools: Financial Projections and Implications

This article examines the impact of financial trends in state‐supported dental schools on full‐time clinical faculty; the diversity of dental students and their career choices; investments in physical facilities; and the place of dentistry in research universities. The findings of our study are the following: the number of students per full‐time clinical faculty member increased; the three schools with the lowest revenue increases lost a third of their full‐time clinical faculty; more students are from wealthier families; most schools are not able to adequately invest in their physical plant; and more than half of schools have substantial NIH‐funded research programs. If current trends continue, the term “crisis” will describe the situation faced by most dental schools. Now is the time to build the political consensus needed to develop new and more effective strategies to educate the next generation of American dentists and to keep dental education primarily based in research universities. The future of the dental profession and the oral health of the American people depend on it.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153587/1/jddj002203372008722suppltb04487x.pd
