according to the unccd definition, “desertification” is land degradation in arid, semi-aridand dry sub-humid areas resulting from various factors, including climatic variations andhuman activities. it has been recognized as a major economic, social, and environmentalproblem in many countries of the world. the medalus methodology is a practical approachto assess the present status of desertifica...

Abstract A powder mixture of UO 2 and TiO was mechanochemically treated in a planetary ball mill under Ar atmosphere for 1 h using tungsten carbide vial balls as the milling medium. Such mechanochemical (MC) treatment reduced crystallinity . The heated at 700–1,300°C 6 analyzed by X-ray diffraction analysis, scanning electron microscopy-energy-dispersive spectroscopy, absorption fine structure ...

in order to study the effect of sowing date and plant density on some quantitative traits and yield of sugar beet genotypes a field experiment was carried out at sugar beet seed production research station of karaj in 2006. treatments arranged in a split, split plot experiment based on completely randomized block design with four replications. the main factors were two sowing dates as 14 april ...

Abstract. Using the diffusion couple technique, of CO2 in a leucititic melt from Colli Albani Volcanic District Italy was investigated at temperatures between 1200 and 1350 ∘C an internally heated pressure vessel 300 MPa. To examine effect dissolved H2O melt, experiments were performed for nominally dry (0.18 ± 0.03 wt % H2O) hydrous containing 3.36 0.28 H2O. Diffusion run 40 to 120 min termina...

Cobalt-free, single crystal layered-oxide positive electrode materials like Li 1+x [Ni 0.6 Mn 0.4 ] 1−x O 2 (NM64) have received recent interest because of their low cost, high-voltage stability, and good cycle life. In this work, NM64 is successfully produced with a simple all-dry synthesis process that requires no water, intermediate chemicals, produces little waste. The synthesized has ≤ 4% ...

PURPOSE To assess inflammatory involvement of cornea in dry eye by means of confocal microscopy, evaluating the presence and distribution of Langherans cells (LCs). METHODS 98 eyes of 49 subjects were enrolled: 18 subjects affected by Sjögren Syndrome Dry Eye (SSDE), 17 with Non-Sjögren Syndrome Dry Eye (NSSDE), 14 healthy volunteeers. Dry eye symptoms, tear film, ocular surface damage and co...
