Abstract
The potential of traceability by nutrients and mineral elements in highland barley (Hordeum vulgare L.) from five cities in Tibet were investigated. The results showed that there were significant differences in nutrients and mineral elements in highland barley from different regions (P < 0.05). The original classification accuracy of linear discriminant analysis (LDA) was 78.3%, and the discrimination accuracy of training set samples based on partial least-squares discriminant analysis (PLS-DA) model was over 65%. The results of correlation analysis show that five elements (Fe, Zn, K, Mn and P) in highland barley are related to the concentration of elements in soil, while three elements (Ca, Cu and Mg) in highland barley have no obvious correlation with soil, because the special natural environment in Tibet affecting the growth of highland barley. This indicates that the origin traceability of highland barley can be achieved by measuring its nutrients and mineral elements.

Abstract
Background:
The elemental composition of maize grains depends on the soil, land and
environment characteristics where the crop grows. These effects are important to evaluate the availability
of nutrients with complex dynamics, such as the concentration of macro and micronutrients in
soils, which can vary according to different topographies. There is available scarce information about
the influence of topographic characteristics (upland and lowland) where culture is developed with the
mineral composition of crop products, in the present case, maize seeds. On the other hand, the study
of the topographic effect on crops using multivariate analysis tools has not been reported.
Objective:
This paper assesses the effect of topographic conditions on plants, analyzing the mineral
profiles in maize seeds obtained in two land conditions: uplands and lowlands.
Materials and Methods:
The mineral profile was studied by microwave plasma atomic emission spectrometry.
Samples were collected from lowlands and uplands of cultivable lands of the north-east of
La Pampa province, Argentina.
Results:
Differentiation of maize seeds collected from both topographical areas was achieved by
principal components analysis (PCA), cluster analysis (CA) and linear discriminant analysis (LDA).
PCA model based on mineral profile allowed to differentiate seeds from upland and lowlands by the
influence of Cr and Mg variables. A significant accumulation of Cr and Mg in seeds from lowlands
was observed. Cluster analysis confirmed such grouping but also, linear discriminant analysis
achieved a correct classification of both the crops, showing the effect of topography on elemental
profile.
Conclusions:
Multi-elemental analysis combined with chemometric tools proved useful to assess the
effect of topographic characteristics on crops.

Abstract
Starch grafted with four different methacrylates was compression molded to form thermoplastic films with good strength and water stability. Starch is an inexpensive and biodegradable polymer but is nonthermoplastic and needs to be chemically modified to make starch suitable for various applications. In this research, starch was grafted with four methacrylates (methyl, ethyl, butyl, and hexyl), and the effect of the length of the alkyl ester group on grafting parameters, thermoplasticity, and properties of thermoplastic films developed have been studied. Influence of grafting conditions on % grafting efficiency, % homopolymers, and % monomer conversion were studied, and the grafted starch was characterized using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and nuclear magnetic resonance ((1)H NMR). At similar grafting ratios, butyl methacrylate (BMA) provided better strength and elongation to the starch films than the other three methacrylates. Grafting of methacrylates appears to be an economical approach to develop thermoplastic products from starch.
