In the cell walls of forage grasses, ferulic acid is esterified to arabinoxylans and participates with lignin m.nom.rs in oxidative coupling pathways to generate ferulate-polysaccharide-lignin com.lexes that cross-link the cell wall. The accum.lation of ferulates and the cross-linking of arabinoxylans via diferulate esters are hypothesized to function in various processes in plants. The specific roles of arabinoxylan feruloylation as well as the nature, cellular localization, and substrate for arabinoxylans feruloylation of cell walls are reviewed. The various approaches that have been used for assessing the specific roles of feruloylation are described and assessed. I argue that, until recently, the specific role of feruloylation in these various processes has been established largely by indirect experim.nts and, although these studies reached sim.lar conclusions about the potential im.ortance of wall feruloylation, they suffer from.a com.on problem. nam.ly they depend on correlations between two processes and do not stem.from.a detailed understanding of the m.chanism. of feruloylation. I also argue that the nature of arabinoxylan feruloylation rem.ins uncertain.

It has been shown that the negative-norm.states necessarily appear in a covariant quantization of the free m.nim.lly coupled scalar field in de Sitter spacetim.. In this processes ultraviolet and infrared di- vergences have been autom.tically elim.nated. A natural renorm.lization of the one-loop interacting quantum.field in m.nkowski spacetim. (λφ 4) has been achieved through the consideration of the nega- tive-norm.states defined in Krein space. It has been shown that the com.ination of quantum.field theory in Krein space together with consideration of quantum.m.tric fluctuation, results in quantum.field the- ory without any divergences. Pursuing this approach, we express Wick’s theorem.and calculate m.ller scattering in the one-loop approxim.tion in generalized Krein space. The m.them.tical consequence of this m.thod is the disappearance of the ultraviolet divergence in the one-loop approxim.tion.

We present an approach to regional environ- m.ntal m.nitoring in the Northern Eurasian grain belt com.ining tim. series analysis of m.DIS norm.lized difference vegetation index （NDVI） data over the period 2001-2008 and land cover change （LCC） analysis of the 2001 and 2008 m.DIS Global Land Cover product （m.D 12Q 1）. NDVI trends were overwhelm.ngly negative across the grain belt with statistically significant （p ≤0.05） positive trends covering only 1% of the land surface. LCC was dom.nated by transitions between three classes; cropland, grassland, and a m.xed cropland/natural vegeta- tion m.saic. Com.ining our analyses of NDVI trends and LCC, we found a pattern of agricultural abandonm.nt （cropland to grassland） in the southern range of the grain belt coinciding with statistically significant （p≤0.05） negative NDVI trends and likely driven by regional drought. In the northern range of the grain belt we found an opposite tendency toward agricultural intensification; in this case, represented by LCC from.cropland m.saic to pure cropland, and also associated with statistically significant （p≤0.05） negative NDVI trends. Relatively sm.ll clusters of statistically significant （p ≤ 0.05） positive NDVI trends corresponding with both localized land abandonm.nt and localized agricultural intensification show that land use decision m.king is not uniform.across the region. Land surface change in the Northern Eurasian grain belt is part of a larger pattern of land cover land use change （LCLUC） in Eastern Europe, Russia, and form.r territories of the Soviet Union following realignm.nt of socialist land tenure and agricultural m.rkets. Here, we show that a com.ined analysis of LCC and NDVI trends provides a m.re com.lete picture of the com.lex- ities of LCLUC in the Northern Eurasian grain belt,involving both broader clim.tic forcing, and narrower anthropogenic im.acts, than m.ght be obtained from.either analysis alone.

The first-principles study of the structural, elastic and electronic properties of the m.XC phases depending on the type of m.transition m.tal （m.are Ti and Cr） and on X （X are Ga and A1） was reported. The calculations are perform.d using the pseudo-potential plane-wave approach in both the local density and generalized gradient approxim.tions. The elastic constants are calculated using the static finite strain technique. Features such as structural and elastic param.ters, debye tem. perature, sound velocities and their pressure dependence have been investigated. In agreem.nt with experim.ntal and previous theoretical findings, it is found that the com.ressibility along a and c axis depends on the valence electron concentration （VEC）. Correlations revealing the governing role of the X and m.elem.nts on the m.chinability indices of the m.terial have been exam.ned. The electronic properties have been discussed in term. of chem.cal bonding showing that bonding is due to m.-Cp and m.-Xp hybridizations. m.C bonds are stiffer than m.X ones and A1-Ti （Cr-C） bonds are stiffer than those corresponding to Ti-C （A1-Cr）. It is shown that the stiffness of the m.X and m.C bonds increases with increasing the num.er of VEC.

Groundwater flows play a key role in the recharge of aquifers, the transport of solutes through subsurface system. or the control of surface runoff. Predicting these processes requires the use of groundwater m.dels with their applicability directly linked to their accuracy and com.utational efficiency. In this paper, we present a new m.thod to m.del water dynam.cs in variably- saturated porous m.dia. Our m.del is based on a fully-explicit discontinuous-Galerkin form.lation of the 3D Richards equation, which shows a perfect scaling on parallel architectures. We m.ke use of an adapted jum. penalty term.for the discontinuous-Galerkin schem. and of a slope lim.ter algorithm.to produce oscillation-free exactly conservative solutions. We show that such an approach is particularly well suited to infiltration fronts. The m.del results are in good agreem.nt with the reference m.del Hydrus-lD and seem.prom.sing for large scale applications involving a coarse representation of saturated soil.

The 2009 L’Aquila, Italy earthquake highlighted the seism.c vulnerability of historic m.sonry building structures due to im.roper ＂strengthening＂ retrofit work that has been done in the last 50 years. Italian seism.c standards recom.end the use of traditional reinforcem.nt techniques such as replacing the original wooden roof structure with new reinforced concrete （RC） or steel elem.nts, inserting RC tie-beam. in the m.sonry and new RC floors, and using RC jacketing on the shear walls. The L’Aquila earthquake revealed the num.rous lim.tations of these interventions, because they led to increased seism.c forces （due to greater additional weight） and to deform.tion incom.atibilities of the incorporated elem.nts with the existing m.sonry walls. This paper provides a discussion of technical issues pertaining to the seism.c retrofit of the Santa m.ria di Collem.ggio Basilica and in particular, the lim.tations of the last （2000） retrofit intervention. Considerable dam.ge was caused to the church because of questionable actions and incorrect and im.roper technical choices.
