Trace radioactive impurities in final construction materials for EXO-200
Leonard, D.S.,Auty, D.J.,Didberidze, T.,Gornea, R.,Grinberg, P.,MacLellan, R.,Methven, B.,Piepke, A.,Vuilleumier, J.-L.,Albert, J.B.,Anton, G.,Badhrees, I.,Barbeau, P.S.,Bayerlein, R.,Beck, D.,Belov, Elsevier 2017 Nuclear instruments & methods in physics research. Vol.871 No.-
<P><B>Abstract</B></P> <P>We report results from a systematic measurement campaign conducted to identify low radioactivity materials for the construction of the EXO-200 double beta decay experiment. Partial results from this campaign have already been reported in a 2008 paper by the EXO collaboration. Here we release the remaining data, collected since 2007, to the public. The data reported were obtained using a variety of analytic techniques. The measurement sensitivities are among the best in the field. Construction of the EXO-200 detector has been concluded, and Phase-I data was taken from 2011 to 2014. The detector’s extremely low background implicitly verifies the measurements and the analysis assumptions made during construction and reported in this paper.</P>

The incidence of acute pancreatitis (AP) has increased in the pediatric population over the past few decades and it stands to follow that the complications of severe AP, including symptomatic pancreatic fluid collections (PFCs) will increase as well. In adults, the therapeutic options for this situation have undergone a dramatic evolution from mainly surgical approaches to less invasive endoscopic approaches, mainly endoscopic ultrasound-guided transmural drainage (EUS-TD) followed be direct endoscopic necrosectomy if needed. This has proven safe and effective in adults; however, this approach has not been well studied or reported in pediatric populations. Here we demonstrate that EUS-TD seems to offer a safe, efficacious and minimally invasive approach to the management of large PFCs in pediatric patients by reviewing two representative cases at our institution.

Two incomplete manuscripts, one only slightly and the other much more so, of Karṇakagomin's (fl. 9th-10th) Pramāṇavārttikavṛttiṭīkā (hereafter PVVṬ) were discovered in Sa skya monastery, Central Tibet, in the early 1930s. The PVVṬ is a study of the Pramāṇavārttikasvavṛtti (hereafter PVSV), Dharmakīrti's (early 7th c.) auto-commentary on the first chapter of his Pramāṇavārttika (hereafter PV), the one that deals with inference. No Tibetan translation of this work is known ever to have been prepared. In the late thirteenth century, an indication of a work by someone whose name is given as either Ka lu ka or Ka lu ka mi tra surfaces in the relevant Tibetan literature. This man is said to have been the author of an exegesis of the PVSV. The name Ka lu ka resurfaces in several fifteenth century Tibetan literary sources as having been the author of a substantial commentary on the PVSV. To my knowledge, Btsun pa Ston gzhon's study of Dharmakīrti's PV of most probably 1297 is so far the only Tibetan work in which a certain Ka lu ka go mi is cited. The citation occurs in his comments on PV, IV: 191c-192, the contents of which Dharmakīrti prefigured in PVSV ad PV, I: 1, and in PV, IV: 37-39. Remarkably, the relevant passage in Karṇakagomin's PVVṬ ad PVSV ad PV, I: 1 is identical with the wording in Arcaṭa's (8th cen.) Hetubinduṭīkā (hereafter HBṬ) ad Dharmakīrti's Hetubindu (hereafter HB) 2.2-4. However, it is quite at odds with the quotation Btsun pa Ston gzhon attributed to Ka lu ka go mi! Hence, I therefore strongly suspect that Ka lu ka go mi and Karṇakagomin are not the same person. The question that now remains is who was this Ka lu ka or Ka lu ka go mi/mi tra?
"Oceanus Resartus"; or, Is Chinese Maritime History Coming of Age?

Perhaps the most salient feature of the transformation of China’s economic policy is its tack into the oceanic sphere. This is a break with the country’s traditional past as an inlandlooking, continental power: the landscape is now complemented by the seascape. This article suggests that China’s new relationship with the sea asks for a master plan for reclaiming a neglected maritime past—the invention of a national maritime tradition, a newly tailored past to explain China’s former relationship with the sea.

The present study investigated the mechanism of physical water treatment through particle count analysis of the water sample with and without physical water treatment (PWT) technology. The PWT methods utilized catalytic devices and low-voltage-high-frequency device wherein water continuously recirculated through them. Concentrated hard water at 2,300-2,700 μS/㎝ electrical conductivity was utilized in the study at two different flow rates (i.e., 500 l/h, and 800 l/h). After 66 hours of operation for each test, the results showed that the total number of particles in the PWT-treated cases increased from 165-539% as compared with the no-treatment cases depending on the flow rate used. The present results provided by particle counting support the bulk precipitation hypothesis as the mechanism of PWT and electro-flocculation mechanism with the use of catalytic materials and LVHF technique.
