The purpose of this study is to evaluate the potential of bio-sourced material based on cereal straw for an efficient insulation. Decreasing significantly energy consumption of buildings requires not only the very best insulation material for heat loss reduction through the wall but also the reduction of air permeability which can affect automatically the comfort in the building. This is why, propose an insulation material with low thermal conductivity remains insufficient and the evaluation of the performance of the new insulation material in situ in real conditions is an essential step. The experimental building ( PROMETHE demonstrator) is set up with wood frame and multilayered walls composed with cinder blocks and insulation bio-composite based on cereal straw in order to simulate the thermal rehabilitation conditions according the External thermal insulation principle. Each façade is divided in four part with three different insulation bio-composites and naked part for comparison reasons. Hygrothermal sensors are used both inside and outside of the demonstrator, and heat-flux sensor is placed at the cinder blocks biocomposite interface. These in situ measurements are used to compare the efficiency of three bi-sourced materials and for the modeling the hygrothermal behavior of the multilayer wall by using the set of identified parameters in laboratory.

Set Up

The diversity and degradation capacity of hydrocarbon-degrading consortia from surface and deep waters of the Eastern Mediterranean Sea were studied in time-series experiments. Microcosms were set up in ONR7a medium at in situ temperatures of 25 °C and 14 °C for the Surface and Deep consortia, respectively, and crude oil as the sole source of carbon. The Deep consortium was additionally investigated at 25 °C to allow the direct comparison of the degradation rates to the Surface consortium. In total, ~50% of the alkanes and ~15% of the polycyclic aromatic hydrocarbons were degraded in all treatments by Day 24. Approximately ~95% of the total biodegradation by the Deep consortium took place within 6 days regardless of temperature, whereas comparable levels of degradation were reached on Day 12 by the Surface consortium. Both consortia were dominated by well-known hydrocarbon-degrading taxa. Temperature played a significant role in shaping the Deep consortia communities with Pseudomonas and Pseudoalteromonas dominating at 25 °C and Alcanivorax at 14 °C. Overall, the Deep consortium showed a higher efficiency for hydrocarbon degradation within the first week following contamination, which is critical in the case of oil spills, and thus merits further investigation for its exploitation in bioremediation technologies tailored to the Eastern Mediterranean Sea.

Set Up

A commercial crystallization robot has been modified for use in setting up sitting-drop vapor-diffusion crystallization experiments, and for setting up protein crystallization screensin situ. The primary aim of this effort is the automated screening of crystallization of integral membrane proteins in detergent-containing solutions. However, the results of this work are of general utility to robotic liquid-handling systems. Sources of error that can prevent the accurate dispensing and mixing of solutions have been identified, and include local environmental, machine-specific and solution conditions. Solutions to each of these problems have been developed and implemented.

Microarray Format

Concepts and results are described for the use of a single, but extremely flexible, probing tool to address a wide variety of genomic questions. This is achieved by transforming genomic questions into a software file that is used as the design scheme for potentially any genomic assay in a microarray format. Microarray fabrication takes place in three-dimensional microchannel reaction carriers by in situ synthesis based on spatial light modulation. This set-up allows for maximum flexibility in design and realization of genomic assays. Flexibility is achieved at the molecular, genomic and assay levels. We have applied this technology to expression profiling and genotyping experiments.
