Indoor air pollution and the contribution of biosensors

pollutants. In the next section, we will describe some conventional methodologies and biosensor techniques are used to determine the IAQ, including the use of genotoxicant bioreporters. Conventional and biosensor techniques for indoor pollutant detection In the previous section, we have identified a list of indoor pollutants that can negatively affect human health and requires monitoring. Various biological, physical and chemical sensors are continuously being developed for this purpose. Four key parameters are usually used to evaluate a sensor’s performance

Polymerization degree-dependent changes in the effects of in vitro chitosan treatments on photosynthetic pigment, protein, and dry matter contents of Ipomoea purpurea

photosynthetic performance in plants. Therefore, it can be said that both chitosan types can increase photosynthetic performance in I. purpurea , based on the findings of our study. This increase might be attributed to enhanced stomatal conductance, transpiration rate and/or cell size and number ( 23 ). In our experiments, the reduced amounts of photosynthetic pigments due to oligomeric chitosan application in increasing concentrations might be attributed to the effects of oxidative damage on the photosynthetic apparatus. This may be because chitosan has been reported to

Biocomposites based on collagen and keratin with properties for agriculture and industrie applications

vegetation, to cover the silicves and to prevent the dehiscence. In these reference works, only the collagen hydrolysates from fish skin has been tested also in rapeseed germination. The present papers refer to application of collagen-based products from bovine skin and wool keratin to stimulate germination of rape seeds and plants nutrition in the start of vegetation. Correlation of this information with other specific data (e.g. with soil characteristics) can lead to the initiation of high-performance rapeseed cultures, reducing the contribution of synthetic

Photosynthetic light reactions in Oryza sativa L. under Cd stress: Influence of iron, calcium, and zinc supplements

analysis considered significant at P ≤ 0.05, n=6. Discussion Chlorophyll fluorescence analysis revealed consequences of nutrient supplements on photosynthetic light reactions during Cd stress. Cadmium accumulation retarded photosynthesis in rice plants ( 19 ). In the present study, a supplement of Fe and Ca helped to restore biomass under Cd stress. This effect was the outcome of maintenance of photosynthetic performance and lowering of Cd accumulation in leaves respectively. But Zn supplement was not effective in the restoration of biomass under Cd stress

Optical properties of translucent zirconia: A review of the literature

favorable mechanical properties and esthetic performance at 0,5-1mm ( 67 ). Conventional zirconia has excellent strength, but its color is white and opaque as chalk; to individualize the color and translucency of a natural tooth, it is required important post-milling work, like stratification of feldspathic porcelain. The introducing of translucent zirconia blocks, which are directly milled into monolithic restorations has been one of the most challenging innovation of the last decade in dentistry. In addition, the translucent zirconia discs are provided in a high

Real time human micro-organisms biotyping based on Water-Assisted Laser Desorption/Ionization

and published ( 18 , 20 ). The identifications were performed directly on the tissue by doing a full scan first to verify the presence of the targeted masses. Then after switching to MS/MS mode, they were subjected to collision-induced dissociation (CID) in the transfer cell with respectively 20 and 35 V. The resulting spectra were annotated manually, and assignments were verified by interrogating the high accuracy mass measurements of the precursor ions using the LipidsMap database.
