Measurement of the mechanical behavior of hydrated gels is challenging due to a relatively small elastic modulus and dominant time-dependence compared with traditional engineering materials. Here polyacrylamide gel materials are examined using different te ...
Groundwater is essential for human activities and is sometimes referred to as a non-renewable resource in the same way as oil and gas. During the past century, precious groundwater reserves worldwide have been threatened by anthropogenic release of chemica ...
PCBs are persistent organic pollutants which have entered the environment through both use and disposal. The environmental dissemination of PCBs is complex and nearly global in scale, although their production was banned in the 80’s. Nowadays, specific bac ...
Protein-polymer conjugates are widely used in biotechnology and medicine, and non-toxic polymers for bioconjugation would be advantageous for these applications. Herein, we reported the toxicity of polymers synthesized by two commonly employed controlled r ...
The genetic diversity of cyanobacterial communities was studied at various depths in Lake Kinneret (Israel). Denaturing gradient gel electrophoresis (DGGE) of specific 16S rRNA gene PCR products showed significant differences in the cyanobacterial communit ...
We present a versatile scheme to rationally modulate the hydrolysis rate of ester bonds in hydrophilic polymer networks via adjacent charged amino acids. As soluble model systems, two cysteine-bearing oligopeptides containing either positively charged argi ...
The variability of the T-RFLP analysis applied to complex microbial communities was assessed statistically. Recent technological improvements were implemented in the successive steps of the procedure, resulting in a standardized procedure which provided a ...
We investigate the fragmentation of an elastic visco-plastic ring in the one-dimensional framework. The governing equations include the effects of large deformation, geometric softening, hydrostatic pressure and material's viscoplasticity. Linear perturbat ...
DNA uptake by polyethylenimine (PEI)-mediated transfection was investigated in Chinese hamster ovary (CHO DG44) cells. Rapid DNA uptake was observed with the maximum occurring during the first 45-60 min after addition of PEI-DNA complexes to cells. With lo ...
• Goal The goal of the project was to produce biomolecular fingerprints in order to describe the structure of microbial community which develops during aerobic sludge granulation, initiated in sequencing batch wastewater treatment processes. Four SBR were ...
