First known terrestrial impact of a binary asteroid from a main belt breakup event.

2014-10-23
Approximately 470 million years ago one of the largest cosmic catastrophes occurred in our solar system since the accretion of the planets. A 200-km large asteroid was disrupted by a collision in the Main Asteroid Belt, which spawned fragments into Earth crossing orbits. This had tremendous consequences for the meteorite production and cratering rate during several millions of years following the event. The 7.5-km wide Lockne crater, central Sweden, is known to be a member of this family. We here provide evidence that Lockne and its nearby companion, the 0.7-km diameter, contemporaneous, Målingen crater, formed by the impact of a binary, presumably 'rubble pile' asteroid. This newly discovered crater doublet provides a unique reference for impacts by combined, and poorly consolidated projectiles, as well as for the development of binary asteroids.

In-field Calibration of a Fast Neutron Collar for the Measurement of Fresh PWR Fuel Assemblies
DOE Office of Scientific and Technical Information (OSTI.GOV)
Swinhoe, Martyn Thomas; De Baere, Paul
2015-04-17
A new neutron collar has been designed for the measurement of fresh LEU fuel assemblies. This collar uses “fast mode” measurement to reduce the effect of burnable poison rods on the assay and thus reduce the dependence on the operator’s declaration. The new collar design reduces effect of poison rods considerably. Instead of 12 pins of 5.2% Gd causing a 20.4% effect, as in the standard thermal mode collar, they only cause a 3.2% effect in the new collar. However it has higher efficiency so that reasonably precise measurements can be made in 25 minutes, rather than the 1 hourmore » of previous collars. The new collar is fully compatible with the use of the standard data collection and analysis code INCC. This report describes the calibration that was made with a mock-up assembly at Los Alamos National Laboratory and with actual assemblies at the AREVA Fuel fabrication Plant in Lingen, Germany.« less

Groundwater can play an important role in lake water and chemical budgets. The aim of this study was to map and quantify groundwater discharge to Lake Steißlingen, a small lake in south-west Germany, using Rn as a natural groundwater tracer. 222Rn, nutrients, temperature and oxygen concentration were measured in depth profiles and in sediment-near water samples during April and June 2016. The spatial distribution of Rn activities (max. 944 Bq m-3) showed that groundwater discharges into the middle of the lake and along the northeastern shore from springs in the hypolimnion (11-14 m depth). Based on a Rn mass-balance groundwater accounts for 70% of the total water input (GWflux = 11 l s-1) to the lake. There were significant positive correlations between methane and nitrite with Rn activity, suggesting the groundwater as a common source. Overall the inflow of groundwater causes a deterioration in lake water quality.

This article has been removed at the request of the Editor-in-chief and Author. Please see Elsevier Policy on Article Withdrawal ( http://www.elsevier.com/locate/withdrawalpolicy). Reason: This article has been retracted at the request of the Editor-in-Chief and Author as the author has plagiarized part of a paper that had already appeared in another journal, as written by the following authors: Roy, Weeks, Rouault, Nelson, Barlow, Van der Lingen. "Extreme oceanographic events recorded in the Southern Benguela during the 1999-2000 summer season", South African J. Sci., 2001, volume 97 (11-12), pp. 465-471. While the underlying scientific data of Dr Krishna's work may be original, the wording, sentence, and paragraph structure of the entire manuscript shows such strong similarity (in many cases wholesale replication of sentences and phrases) that we must conclude that there has been excessive use of previously published material without appropriate attribution and is consequently not an original contribution. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.

The increasing imprisonment rate of drug users is linked to a spread of infectious diseases in prisons (HIV and Hepatitis B and C). Several studies indicate a close correlation of imprisonment and transmission of infectious diseases. An analysis of international studies showed that worldwide in several cases transmissions of HIV-infection during imprisonment have been discovered. The cross-sectional examination presented here is describing the situation in the women's prison of Vechta (Lower-Saxony). Empirical data on the prevalence of infections with HIV, HBV, HCV and Lues of the years 1992 to 1994 were recorded. Moreover the scientific interest also included on the diagnosis of seroconversions. Discovered seroconversions were examinated on a possible transmission in custody. The spread of infectious diseases in prisons led to the demand for an alignment of internal drug aid services with external, tried and tested prophylaxis models. The availability of sterile syringes is included. The basic comparability of health care inside and outside prison (principle of equivalence) is not only demanded and recommended by the prison law [4] but also by international organisations [27]. As the first provencial government, the state of Lower Saxony in Germany has started to develop infection prophylaxis offers in two prisons (in the women's prison in Vechta since April 15th 1996 and in the men's prison of Lingen I, department Gross Hesepe since July 15th 1996) in 1996. These offers include the provision of sterile injection equipment to intravenous drug addicts (ivDA). Modalities of the practice and first experiences documented by the schientific evaluation are presented.

Shock wave therapy for chronic proximal plantar fasciitis.

Three hundred two patients with chronic heel pain caused by proximal plantar fasciitis were enrolled in a study to assess the treatment effects consequent to administration of electrohydraulicall-generated extracorporeal shock waves. Symptoms had been present from 6 months to 18 years. Each treated patient satisfied numerous inclusion and exclusion criteria before he or she was accepted into this study, which was approved by the Food and Drug Administration as a randomized, double-blind evaluation of the efficacy of shock wave therapy for this disorder. Overall, at the predetermined evaluation period 3 months after one treatment, 56% more of the treated patients had a successful result by all four of the evaluation criteria when compared with the patients treated with a placebo. This difference was significant and corroborated the fact that this difference in the results was specifically attributable to the shock wave treatment, rather than any natural improvement caused by the natural history of the condition. The current study showed that the directed application of electrohydraulic-generated shock waves to the insertion of the plantar fascia onto the calcaneus is a safe and effective nonsurgical method for treating chronic, recalcitrant heel pain syndrome that has been present for at least 6 months and has been refractory to other commonly used nonoperative therapies. This technology, when delivered using the OssaTron (High Medical Technology, Kreuz-lingen, Switzerland), has been approved by the Food and Drug Administration specifically for the treatment of chronic proximal plantar fasciitis. The results suggest that this therapeutic modality should be considered before any surgical options, and even may be preferable to cortisone injection, which has a recognized risk of rupture of the plantar fascia and recurrence of symptoms.
