green onion is one of the most consumed vegetables in Colombia. However, its production is negatively affected by the nematode Ditylenchus. to determine the species of the nematode, as well as to propose management strategies for its control, in the present study the morphological, morphometric, and molecular characterization of the phytonematode was carried out and was used to evaluate the effect of immersion of the propagation material in water hot, application of a commercial strain of Purpureocillium lilacinum and the application of an agrochemical with insecticidal-nematicidal action to control the phytosanitary problem under field conditions. the morphological and morphometric characteristics of the nematode were similar to those reported for the type and reference populations of D. dipsaci. Based on sequences of the D2-D3 segment and Internal transcribed spacer-Its of the rRNA, the presence of D. dipsaci in green onion crops in Colombia was confirmed. the application of P. lilacinum statistically showed an efficient control of D. dipsaci, at the same time that presented the highest yield, in relation to the other evaluated treatments (P ≤ 0.05).

An unusual F_(3)basal stacking fault resulting from twin-dislocation interaction in magnesium is observed in molecular dynamics *** F_(3)fault is produced in the twin lattice from the interaction between a migrating(1012)twin boundary and a partial dislocation of either a prismaticedge,or a prismaticmixed dislocation in the *** condition is that the partial dislocation needs to have a negative sign and lie on a plane intersecting a compression site of the twin *** F_(3)fault can also be generated when a positive basalmixed dislocation in the twin lattice,with slip plane intersecting a compression site of the twin boundary,interacts with a basal-prismatic twinning *** F_(3)fault comprises two I_(1) faults that have the same character but are separated by two basal *** has one end connected to the twin boundary,and the other end bounded by a lattice defect with a Burgers vector identical to that of a 30°shockley partial *** formation frequency of the F_(3)fault is higher at a lower shear stress(below∼400 MPa)and/or a lower temperature(100 K and 200 K).the F_(3)fault can decompose into a glissile 30°shockley and a t_(2) fault at a temperature above∼400 *** relationships between the F_(3)fault and other types of basal stacking faults such as I_(2),t_(2) or paired I_(1) faults that are separated by multiple basal layers are discussed.

the effect of annual additions of composted sewage sludge (Cs) and thermally dried sewage sludge (ts) at 80 t ha-1 on soil chemical properties was investigated for three years in a field experiment under semiarid conditions. Humic acids (HAs) isolated by conventional procedures from Cs, ts, and unamended (sO) and sludge amended soils were analysed for elemental (C, H, N, s and O) and acidic functional groups (carboxylic and phenolic) and by ultraviolet-visible, Fourier transform infrared and fluorescence spectroscopies. With respect to Cs, ts had similar pH and total P and K contents, larger dry matter, total organic C, total N and C/N ratio and smaller ash content and electrical conductivity. Amendment with both Cs and ts induced a number of modifications in soil properties, including an increase of pH, electrical conductivity, total organic C, total N, and available P. the Cs-HA had greater O, total acidity, carboxyl, and phenolic OH group contents and smaller C and H contents than ts-HA. the Cs-HA and ts-HA had larger N and s contents, smaller C, O and acidic functional group contents, and lower aromatic polycondensation and humification degrees than sO-HA. Amended soil-HAs showed C, H, N and s contents larger than sO-HA, suggesting that sludge HAs were partially incorporated into soil HAs. these effects were more evident with increasing number of sludge applications.

the reactions γd→π-pp and γd→npπ+π-have been studied in an energy range from 0.8 to 1.1 geV at the tagged photon facility of Laboratory of Nuclear science,tohoku University. Charged pions and protons in the final state were measured by using the Neutral Kaon spectrometer (NKs2). the analysis of the γd→π-pp was mainly used to check the acceptance of the NKs2 and to calibrate the tagged photon energy. the photoproduction of the Δ++Δ-was identified in the γd→npπ+π-reaction. since the data analyses are still in progress,we issue an interim report and preliminary results.

the K?z?l?rmak River is turkey?s longest(1,355 km) river and it is important since it constitutes the drinking and irrigation water source of the Central Anatolia Region. In the current study, the spatial distribution, effect on irrigation water quality, environmental pollution status, ecotoxicological and health risks as well as possible sources of 12 potential toxic elements?(PtEs)(manganese(Mn),aluminum(Al), arsenic(As), chromium(Cr), zinc(Zn), iron(Fe), nickel(Ni), cadmium(Cd), cobalt(Co),copper(Cu), mercury(Hg), and lead(Pb)) concentrations from surface water samples in the K?z?l?rmak River were analyzed by using geographical information systems(gIs) software, ecotoxicological indices,and multivariate statistical analysis. As a result of the current study, it was determined that the As concentration is above the World Health Organization(WHO) limit values, and, in terms of the 12 PtEs,there is slight heavy metal contamination in the river according to the Heavy Metal Pollution Index(HPI)and Heavy Metal Evaluation Index(HEI) values and there is a low level of pollution. the Hazard Quotient for ingestion(HQingestion) and Hazard Index(HI) values indicate that non-carcinogenic effects may *** to river water is likely to result in a low level of carcinogenic risk(CR) in adults, mainly due to the As concentration. the water at sampling station s3(131.79) cannot be used for drinking and is not suitable for consumption. According to the sodium percentage(Na%), sodium Absorption Ratio(sAR),and Magnesium Hazard(MH) index results, river water is suitable for agricultural use.
