Abstract Two experiments were performed in 2011-2012 to investigate the response of three oilseed rape cultivars to drought stress, grown under two climate conditions in Iran (cold and hot climates). The experiments were conducted using a randomized complete-block design arranged in split-plot with three replicates. The irrigation treatments (FI: full irrigation; WIF: withholding irrigation at flowering stage, and WIS: withholding irrigation at the silique formation stage until physiological maturity) were allocated to main plots, whereas subplots consisted of the oilseed rape cultivars: early maturating (GKH2005), relatively late maturing (Opera) and late maturing (Okapi). Drought caused a… More >

Abstract Ulmus macrocarpa Hance can form monodominant woodlands in the semiarid Keerqin sandy lands, China. Methods of sampling at meter intervals from the bases of trees at the woodland edges and isolated trees, respectively, were employed along vertical sections in different directions. Using statistical methods based on the density function of the Weibull distribution, the patterns of seed dispersal and the spatial expansion response of U. macrocarpa, which is a typical anemochorous plant, were analyzed. Although as an effect of the wind direction varying owing to the monsoon, there were differences in the degree of dispersal of seeds… More >

Abstract Abiotic stresses like salt stress and soil compaction are responsible for increased ethylene production which may adversely affect crop growth. A field experiment was conducted to evaluate the response of seed inoculation with ACC-deaminase containing rhizobacteria (Pseudomonas fluorescens and Pseudomonas syringae) in the presence of recommended or half of a recommended rate of inorganic fertilizers at different growth stages of fodder maize in a compacted saline-sodic soil. At both fertilizer rates, seed inoculation with P. fluorescens and P. syringae significantly improved all growth parameters over the control treatment. After 30, 60 and 75 days of sowing, treatment with recommended… More >

Abstract Linseed oil was epoxidized using hydrogen peroxide (H2O2), acetic acid (AcOH) and ion exchange resin Amberlite IR-120 as a catalyst. Epoxidized oil was separately dissolved in isopropyl alcohol (IPA) or diethylene glycol butyl ether (DGBE) and phosphorylated with different amounts of phosphoric (H3PO4) acid (1%, 2%, 3% and 5%). The formation of phosphate polyesters was confirmed by Fourier-transform infrared (FTIR) and 31P nuclear magnetic resonance (NMR) spectra. Based on the synthesized polyols, polyurethane (PU) coatings were prepared. PU coating based on linseed oil diethylene glycol ester polyol was used as the reference. For the characterization More >

Abstract This article deals with the study of the viscoelastic and thermal properties of polyurethane (PU) rigid foams from biobased and recycled components. Rapeseed oil (RO) and recycled poly(ethylene terephthalate) (PET) were used to synthesize PU polyols. Addition of adipic acid (ADA) to polyol resulted in improved thermal and viscoelastic properties of foam materials. ADA content was varied from 1 to 6 wt%. Results of the dynamic mechanical spectra indicate an increase of the storage modulus E′ and the loss modulus E″ in the whole temperature range for specimens with higher loading of ADA. In addition, More >

Abstract In this study, different samples of alkyd resins based on Citrullus colocynthis seed oil (CCSO)—which has a high content of linoleic acid—were prepared as a renewable raw material. Short (I), medium (II), and long (III) alkyd resins were synthesized using oil, glycerol, and phthalic anhydride (PA) in different proportions. Prunus mahaleb seed oil (PMSO), which contains conjugated linolenic acid, was blended with CCSO in different proportions to examine the effect of PMSO on the film properties of alkyd resins (IV and V). All synthesized resins were characterized by FTIR and 1H NMR spectroscopic analysis. These More >

Abstract Elastomeric polyurethanes were prepared from a reference polyurethane system modified with biobased polyols synthesized using rapeseed or palm oils. The reference material was modified by replacement of the commercial polyol by 10% of biopolyols and also by addition of sisal fibers up to 5 wt%. The higher functionality of the biopolyols increased the crosslinking density of the networks and this was reflected by an increase in hardness and a decrease in water absorption. The effect of the sisal fibers mainly improved the mechanical and thermomechanical properties of the system with rapeseed oil because of good More >

Abstract The explosive growth of mobile data demand is becoming an increasing burden on current cellular network. To address this issue, we propose a solution of opportunistic data offloading for alleviating overloaded cellular traffic. The principle behind it is to select a few important users as seeds for data sharing. The three critical steps are detailed as follows. We first explore individual interests of users by the construction of user profiles, on which an interest graph is built by Gaussian graphical modeling. We then apply the extreme value theory to threshold the encounter duration of user More >

Abstract Steganography technology has been widely used in data transmission with secret information. However, the existing steganography has the disadvantages of low hidden information capacity, poor visual effect of cover images, and is hard to guarantee security. To solve these problems, steganography using reversible texture synthesis based on seeded region growing and LSB is proposed. Secret information is embedded in the process of synthesizing texture image from the existing natural texture. Firstly, we refine the visual effect. Abnormality of synthetic texture cannot be fully prevented if no approach of controlling visual effect is applied in the More >

Abstract Introduction: We tested different classification systems in order to separate intermediate-risk prostate cancers into prognostic groups. We then examined which groups were most suited for either prostate seed brachytherapy (PB) or external beam radiotherapy (EBRT).
Materials and methods: We selected patients with D'Amico intermediate-risk prostate cancer who were treated exclusively with either PB or EBRT. Patients were excluded if they had received androgen deprivation therapy in combination with EBRT or a follow up of < 30 months without recurrence. The Kaplan-Meier method was used to compare groups.
Results: Our sample consisted of 475 patients treated from July 2002-September… More >
