BAc.GROUND: Point-of-c.re ultrasound has gained widespread use in developing c.untries due to dec.eased c.st and improved telemedic.ne c.pabilities. Ultrasound training, spec.fi c.lly image ac.uisition skills, is oc.urring with more frequenc. in non-medic.l personnel with varying educ.tional levels in these underdeveloped areas. This study evaluates if students without a high sc.ool educ.tion c.n be trained to ac.uire useful FAST images, and to determine if an 8^(th) grade student c.n teac. peers these ***: The 8^(th) grade students at a small middle sc.ool were divided into two groups. One group rec.ived training by a c.rtified medic.l sonographer, while the other group rec.ived training by a peer 8^(th) grade student trainer who had previously rec.ived training by the sonographer. After training, eac. student was independently tested by sc.nning the four FAST loc.tions. A blinded ultrasound expert evaluated these images and deemed eac. image adequate or inadequate for c.inic.l ***: Eighty video image c.ips were obtained. The overall image adequac. rate was 74%. The splenorenal window had the highest rate at 95%, followed by retrovesic.l at 90%, hepatorenal at 75%, and subxiphoid c.rdiac.at 35%. The adequac. rate of the sonographer-trained group was 78%, while the adequac. rate of the student-trained group was 70%. The differenc. in image adequac. rate between the two groups was not signifi c.nt(P-value 0.459).c.Nc.USION: The majority of 8^(th) graders obtained c.inic.lly adequate FAST images after minimal training. Additionally, the student-trained group performed as well as the sonographer-trained group.

Global Agric.ltural Trade and Developing c.untries presents researc. findings based on a series of c.mmodity studies of signific.nt ec.nomic.importanc. to developing c.untries. First, the book sets the stage with bac.ground c.apters and investigations of c.oss-c.tting issues. Trade and domestic.polic. regimes affec.ing agric.ltural and food markets are desc.ibed, and the resulting patterns of produc.ion and trade are assessed. The book follows with an analysis of produc. standards and c.sts of c.mplianc. and their effec.s on agric.ltural and food trade. An investigation of the impac. of preferenc.s given to selec.ed c.untries and their effec.iveness is next. The evidenc. on the attempts to dec.uple agric.ltural support from agric.ltural output is then reviewed. The last bac.ground c.apter explores the robustness of the global gains of multilateral agric.ltural and food trade liberalization. Given this c.ntext, the book presents detailed c.mmodity studies for c.ffee, c.tton, dairy, fruits and vegetables, groundnuts, ric., seafood produc.s, sugar, and wheat. These markets feature distorted polic. regimes among industrial or middle-inc.me c.untries.; The studies analyze c.rrent polic. regimes in key produc.ng and c.nsuming c.untries doc.ment the magnitude of these distortions and estimates the distributional impac.s -winners and losers- of trade and domestic.polic. reforms. By bringing the key issues and findings together in one plac., Global Agric.ltural Trade and Developing c.untries aids polic. makers and researc.ers, both in their approac. to global negotiations and in evaluating their domestic.polic.es on agric.lture. This book also c.mplements the rec.ntly published Agric.lture and the WTO that foc.ses primarily on the agric.ltural issues within the c.ntext of the WTO negotiations.

Ac.urately quantifying rates of soil erosion requires c.pturing both the volumetric.nature of the visible,c.nvergent fluvial pathways(also known as rills)and the subtle nature of the less-visible,diffuse pathways(interrill areas).The aim of this study was to use Rare Earth Oxide(REO)trac.rs and Struc.ure-from-Motion(SfM)photogrammetry to eluc.date retrospec.ive information about soil erosion rates and sediment sourc.s during different soil erosion c.nditions,within a c.ntrolled laboratory *** experimental c.nditions c.eated erosion events c.nsistent with diffuse and c.nvergent erosion *** trac.rs allowed the sediment transport distanc.s of over 2 m to be desc.ibed,and helped resolved the relative c.ntribution of diffuse and c.nvergent soil erosion;interrill areas were also iden-tified as a signific.nt sediment sourc.s soil loss under c.nvergent erosion *** the potential for SfM photogrammetry to resolve sub-millimetre elevations c.anges was demonstrated,under some c.nditions non-erosional c.anges in surfac. elevation,suc. as c.mpac.ion,exc.eded volumes of soil loss via diffuse *** disc.epanc.es between SfM Photogrammetry c.lc.lations and REO tagged sediment export were benefic.al,identifying that during soil erosion events sediment in both aggregate and partic.e form is deposited within the c.nvergent features,even when the rill extended the full length of the soil *** c.mbination of SfM photogrammetry and REO trac.rs has provided a novel platform for building a spatial understanding of patterns of soil loss and sourc. apportionment between rill and interrill erosion.
