Root cortical senescence (RCS) in Triticeae reduces nutrient uptake, nutrient content, respiration, and radial hydraulic conductance of root tissue. We used the functional-structural model SimRoot to evaluate the functional implications of RCS in barley (Hordeum vulgare) under suboptimal nitrate, phosphorus, and potassium availability. The utility of RCS was evaluated using sensitivity analyses...

In order to overcome the brittleness of polylactide (PLA), reactive core-shell particles (RCS) with polybutadiene as core and methyl methacrylate-co-styrene-co-glycidyl methacrylate as shell were prepared to toughen PLA. Tert-dodecyl mercaptan (TDDM) was used as chain transfer agent to modify the grafting properties (such as grafting degree, shell thickness, internal and external grafting) of t...

The outboard corner reflectors are widely used as a countermeasure to radar tracking and detection. Therefore, it is essential determine the composite time-domain scattering characteristics of reflector ship against sea background jamming effectiveness array. In this paper, electromagnetic target, reflector, surface studied based on bouncing ray method (TDSBR). echo broadband cross section (RCS...

The Reticulum Cell Sarcoma (RCS)' is a spontaneous lymphatic tumor of the SJL/J (H-29) mouse, first observed by Murphy (1) in upwards of 90% of SJL/J mice of amean age of 13 .3 mo. RCS tumors are considered B cell lineage neoplasms that exhibit Ig H chain gene rearrangements, but no surface or cytoplasmic Ig (2). Additionally, RCS tumors express IAs MHC-encoded polypeptides (3) . RCS tumors req...

The effect of light- and dark-rearing on the amounts of rhodopsin and interstitial retinol-binding protein (IRBP) in RCS rats and their congenic controls (RCS-rdy+) was determined. Rhodopsin was measured spectroscopically and IRBP by dot-blot enzyme immunoassay utilizing rabbit antibovine IRBP IgG. After P15-20, dark-reared RCS and RCS-rdy+ rats always had more rhodopsin than their light-reared...

The Rcs phosphorelay system, a non-orthodox two-component regulatory system, integrates environmental signals, regulates gene expression, and alters the physiological behavior of members of the Enterobacteriaceae family of Gram-negative bacteria. Recent studies of Rcs system focused on protein interactions, functions, and the evolution of Rcs system components and its auxiliary regulatory prote...

tsimpli and dimitrakopoulou (2007) observed that uninterpretable features are unavailable in second language (l2) acquisition after the critical period. in this paper, we verify this claim by providing evidence from persian speaking learners of english as an l2 on the status of resumptive pronouns (rps) as uniterpretable features. unlike english which does not allow rps, persian shows various b...
