Climate chang. predictions for the Pacific Northwest reg.on of the United States of America include increasing.temperatures, intensification of winter precipitation, and a shift from mixed snow/rain to rain-dominant events, all of which may increase the risk of soil erosion and threaten ag.icultural and ecolog.cal productivity. Here we used the ag.icultural/environmental model SWAT with climate predictions from the Coupled Model Intercomparison Project 5 (CMIP5) “hig. CO2 emissions” scenario (RCP8.5) to study the impact of altered temperature and precipitation patterns on soil erosion and crop productivity in the Willamette River Basin of western Oreg.n. An ensemble of 10 climate models representing.the full rang. in temperature and precipitation predictions of CIMP5 produced substantial increases in sediment yield, with differences between yearly averag.s for the final (2090-2099) and first (2010-2019) decades rang.ng.from 3.9 to 15.2 MT·ha-1 among.models. Sediment yield in the worst case model (CanESM2) corresponded to loss of 1.5 - 2.7 mm·soil·y-1, equivalent to potentially stripping.productive topsoil from the landscape in under two centuries. Most climate models predicted only small increases in precipitation (an averag. of 5.8% by the end of the 21st century) combined with larg. increases in temperature (an averag. of 0.05°.C·y-1). We found a strong.correlation between predicted temperature increases and sediment yield, with a reg.ession model combining.both temperature and precipitation effects describing.79% of the total variation in annual sediment yield. A critical component of response to increased temperature was reduced snowfall during.hig. precipitation events in the wintertime. SWAT characterized years with less than basin-wide averag.s of 20 mm of precipitation falling.as snow as likely to experience severe sediment loss for multiple crops/land uses.

The present work discusses the friction and wear of polyamide sliding.ag.inst steel in the presence of mag.etic field. Tests were carried out at dry and oil lubricated steel surfaces. Paraffin and veg.table oils such as almond, castor, corn, g.ycerine, jasmine, olive and sun flower oils were used as lubricants. The friction coefficient and wear were investig.ted using.pin on disc wear tester. Based on the experimental results, it was found that application of mag.etic field on the contact area affected both friction coefficient and wear of polyamide sliding.ag.inst steel at dry and oil lubricated conditions. Mag.etic field decreased friction coefficient. Lubricating.the sliding.surface by paraffin oil as well as almond, castor, corn, g.ycerine, jasmine, olive and sun flower oils sig.ificantly decreased friction coefficient. g.nerally, friction coefficient increased with increasing.applied load. Dry sliding.of polyamide ag.inst steel surface showed increased wear with increasing.load. The lowest wear values at no mag.etic field were displayed by jasmine oil followed by sun flower, almond, olive, castor, corn, g.ycerine and paraffin oils. Under the application of mag.etic field, the lowest wear values were displayed by sun flower oil followed by jasmine, castor, g.ycerine, olive, paraffin, almond and corn oils. It can be concluded that friction and wear decrease observed at dry sliding.can be explained on the basis that presence of mag.etic field around the contact area decreased the adherence and transfer of polyamide into the steel surface. For oil lubricated sliding. the polar molecules of the tested lubricating.oils were much affected by the mag.etic field, where they oriented themselves to the polar end directed towards the sliding.surface making.a close packed multi-molecular layered surface film that could protect the sliding.surfaces from excessive wear.

Panax g.nseng.C.A. Meyer is an endang.red species in Russia. To restore this species, effective protective measures, including.the reintroduction into favorable habitats, must be worked out considering.the specificity of g.netic structure of g.nseng.populations. One hundred and thirty-nine P. g.nseng.plants were collected from the forests of nine administrative areas of Primorsky Territory of Russia and transferred to a collection nursery for further investig.tion. Microsatellite markers were used to study the g.netic diversity and the g.netic structure of g.nseng.populations. For populations studied with SSR, the number of observed alleles was rang.ng.from 15 to 25, allelic richness from 1.83 to 3.04, polymorphic loci from 62.5% to 87.7%, observed heterozyg.sity from 0.410 to 0.512 (an averag. of 0.453) and expected heterozyg.sity from 0.304 to 0.479, with an averag. of 0.393. The values of the inbreeding.coefficient within populations (Fis) rang.d from -0.447 to 0.056, and their averag. value was -0.296. g.netic differentiation among.populations was sig.ificant (Fst = 0.115) but an isolation-by-distance pattern was not detected. UPg.A and MS-tree confirmed the presence of g.netic structure within P. g.nseng.and visualized g.netic relationships of populations with similar pattern. STRUCTURE analysis revealed the g.netic admixture between different g.nseng.populations. It was established with SSR markers that P. g.nseng.still preserves substantial g.netic resources althoug. all populations are larg.ly exhausted. Because g.nseng.populations are sig.ificantly differentiated all of them should be restored. Considering.the admixture of g.nseng.populations it would be advisable to apply the individual assig.ment test to verify the content of indig.nous populations and to identify the "true" population plants to serve as stock material for reintroduction.

Necropsies and extensive histolog.cal evaluation for clinical and sub-clinical disease of approximately three hundred Portug.ese Water dog. are available as part of an ong.ing.study to assess their state of health at the end of life. Throug.out life these dog. enjoyed a variety of lifestyles and environments. Here we carry out retrospective quantitative assessments of life-time dietary input and physical activity for each dog. To do this, collag.ns from skull vault bone and from dentine have been analyzed for ratios of stable isotopes to determine differences in diet that individual dog. experienced during.late or early life respectively. Robustness of skull bone (weig.t/unit of skull size) was used as a relative indicator of the amount of physical activity experienced during.a dog.s lifetime. These environmental parameters were correlated with the frequency and severity of specific disease processes determined at necropsy. Both measures were shown to exert sig.ificant low-level

The stability of three water-based slurries containing.different loads of Al microparticles was measured by laser scattering. The slurries displayed a Newtonian behaviour and the evolution of viscosity over nine days was found to be constant. g.ound surfaces of nickel were also wetted similarly irrespective of the Al content in the slurries (30, 40 or 50 wt%) thereby demonstrating.that the 1/10 PVA/H2O water based slurries are adequate for spraying. After deposition and annealing.of the as-sprayed coating., a thermal barrier coating.system was formed with a top coat of hollow alumina spheres, an intermediate thermally g.own oxide and a bottom aluminized bond coat. The coating.system is shown to display very low thermal conductivity and remarkable oxidation resistance at hig. temperatures.

Schizophrenia is a disease that affects many areas of the brain. The dopamine hypothesis is one of the most widely-accepted ideas in the pathophysiolog. of schizophrenia. Besides alterations in the dopaminerg.c system in the central nervous system, there have been several reports of chang.s in dopaminerg.c systems in the peripheral blood of schizophrenic patients. Several reports have shown that dopamine receptor expression by lymphocytes is altered in patients with schizophrenia, but the results have been conflicting. We therefore re-assessed D3R and D4R mRNA levels in 11 patients with schizophrenia and 12 healthy subjects and correlated levels with severity of symptoms. D3R and D4R expression in lymphocytes and g.anulocytes was measured by quantitative RT-PCR and the severity of symptoms and cog.itive impairment were assessed using.the PANSS and BACS-J. There were no sig.ificant differences in mean D3R or D4R mRNA levels in lymphocytes from schizophrenic patients and controls and no sig.ificant difference in mean D4R mRNA levels in g.anulocytes (D3R mRNA undetectable). In patients with schizophrenia, D3R expression was inversely correlated with the total PANSS score (r = 0.768, p = 0.009), while D4R expression was positively correlated with working.memory scales (r = 0.895, p = 0.001). In conclusion, these results imply that lymphocyte D3R and D4R are involved in the mechanisms of the disorder and could be used as targ.t markers in the treatment of schizophrenia.
