The 1930’s American Dust Bowl was an environmental catastrophe, associated with massive erosion across parts of the Great Plains. Analyzing new data collected to identify low-, medium-, and high-erosion counties, the Dust Bowl is estimated to have substantially reduced agricultural land values and revenues. During the Great Depression and through at least the 1950’s, there was limited reallocat...

With the Doha Round of the WTO stalled indefinitely, bilateral free trade agreements (FTAs) have proliferated. While countries in Asia were relative latecomers to preferential liberalization, they have been catching-up rapidly. Indeed, the proliferation of FTAs has been greatest in Asia over the past decade. As of January 2013, there are 109 FTAs involving an Asian country already in effect, 13...

Density functional techniques including gradient corrections are used to investigate the relative energies of the ring, bowl (corannulene-like), and cage ( fullerene-like) isomers of Cl,,. In agreement with previous studies, the local density approximation yields the cage to be the most stable isomer with the bowl and ring forms being significantly higher in energy. However, the inclusion of gr...

Dry (mechanochemical) synthesis of Y(BH4)3. For mechanochemical synthesis the vibrating mill (Testchem) and chromium steel bowl and disc were used. Substrates, YCl3 and LiBH4 were mixed in ca 1:3 molar ratio (with a 5 % excess of MBH4) and milled for ca. 60 minutes in Ar atmosphere. Milling periods of 3–5 minutes were altered with 2–5 minutes rests to avoid thermal decomposition of the products...

Gaining adequate visual exposure and mechanical access to tumors arising in the conchal bowl area can be difficult. Having a surgical assistant flatten the natural concavity of the bowl with pressure from behind may be of some help. Furthermore, the use of an angled beaver blade may improve the maneuverability of the scalpel in this tight space. However, even with these adjunctive measures, sur...

An analytic solution to the mild slope wave equation is derived for long waves propagating over a circular, bowl-shaped pit located in an otherwise constant depth region. The analytic solution is shown to reduce to a previously derived analytic solution for the case of a bowl-shaped enclosed basin and to agree well with a numerical solution of the hyperbolic mild-slope equations. The effects of...

Anteverted conchal bowl is a congenital deformity; in which the convex. This condition affects external appearance and also hearing via obstructing opening of acoustic meatus. In neonatal stages it can be corrected non-surgically, where as childhood or an adult, needs surgical correction. Here we present case patient was surgically treated ENT Unit - GH Ampara, Sri Lanka along with methods util...

Coreference is a core nlp problem. However, newswire data, the primary source of existing coreference data, lack the richness necessary to truly solve coreference. We present a new domain with denser references—quiz bowl questions—that is challenging and enjoyable to humans, and we use the quiz bowl community to develop a new coreference dataset, together with an annotation framework that can t...

The mol-ecule of O-acetyl-swietenolide, C(29)H(36)O(9), isolated from the seeds of Swietenia macrophylla, features four six-membered rings connected together in the shape of a bowl; one of the inner rings adopts a twisted chair conformation owing to the C=C double bond. The furyl substitutent is connected to an outer ring, and it points away from the bowl cavity. The hy-droxy group is connected...
