Soil pollution is a threat to food security and ecological human health. Cd one of the most common pollutants in agricultural soil and, due its toxicity, hazardous. Amaranth documented hyperaccumulator other pollutants, it commonly grown Asia South America. A considerable amount amaranth suboptimal conditions, including nutrient-poor acidic soils. The objective this experimental study was exami...

We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orient...

We present some numerical results obtained from a simple individual-based model that describes clustering of organisms caused by competition. Our aim is to show that, even when a deterministic description developed for continuum models predicts no pattern formation, an individual-based model displays well-defined patterns, as a consequence of fluctuation effects caused by the discrete nature of...

The aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a Holstein dairy farm in Iran. A retrospective epidemiological survey from April 2005 to March 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. Data of each case including calendar-date of mastitis onset, days in milk ...

The reliability of accelerometry for measuring sedentary behavior in preschoolers has not been determined, thus we determined how many days of accelerometry monitoring are necessary to reliably estimate daily time spent in sedentary behavior in preschoolers. In total, 191 and 150 preschoolers (three to five years) wore ActiGraph accelerometers (15-s epoch) during the in-school (≥4 days) and the...

We studied the persistence of porcine reproductive and respiratory syndrome virus (PRRSV) in individual experimentally infected pigs, during a period of up to 150 days postinfection (dpi). The results of this study suggest that the persistence of PRRSV involves continuous viral replication but that it is not a true steady-state persistent infection. The virus eventually clears the body and seem...

For the purposes of this investigation, specimens of urine from 150 children, aged 2 months 4o 5 years, healthy and diseased (other than recognized diabetes), were examined for reducing substances both by Fehling's and Benedict's methods. Three specimens, taken on three successive days, were thus examined, and when a reducing substance was detected, the nature of the sugar was determined by the...

Several types of WLS bres, candidates to be used in the TILECAL/ATLAS detector, were irradiated in a 60 Co source. Bicron, Kuraray and Pol.Hi.Tech bres were exposed to a total dose of 150 Krad. The degradation of light output was measured just after irradiation and followed during several days. The results are presented.
