#1
Ranajay Ghosh, Hamid Ebrahimi, Ashkan Vaziri
Biomimetic scales are known to substantially alter the mechanics response of the underlying substrate engendering complex nonlinearities that can manifest even in small deformations due to scales interaction. This interaction is typically modeled using a-priori homogenization with an enforced periodicity of engagement. Such a framework is fairly useful especially when dealing with the structural length scale which is at least one order of magnitude greater than the scales themselves since individual tracking of a large number of scales become insurmountable...

The results presented in this study were carried out as concomitant experiments during the start-up and operation of a biomethanation unit to evaluate the effect of process parameters on carbon conversion, product formation (methane and acetate) and community composition. For that, two different samples were withdrawn from a trickle-bed reactor with immobilized enrichment culture of hydrogenotrophic methanogens adapted from sewage sludge. One sample was taken from the recirculation liquid during start-up phase while the other was withdrawn directly from the carrier material in the reactor...

The NaHCO3/red-mud (RM) composite powders were successfully prepared by the solvent-anti-solvent method for methane explosion suppression. The RM was used as a carrier, and the NaHCO3 was used as a loaded inhibitor. The NaHCO3/RM composite powders showed a special core-shell structure and excellent endothermic performance. The suppression properties of NaHCO3/RM composite for 9.5% CH4 explosion were tested in a 20L spherical explosion vessel and a 5L Perspex duct. The results showed that the NaHCO3/RM composite powders displayed a much better suppression property than the pure RM or NaHCO3 powders...

Nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) are efficient soluble intracellular sensors that activate defense mechanisms against pathogens. In teleost fish, the involvement of NLRs in the immune response is not well understood. However, recent work has evidenced the expression of different NLRs in response to some pathogen associated molecular patterns (PAMPs). In the present work, the cDNA sequence encoding three new NOD-like receptors were identified in Oncorhynchus mykiss, namely OmNLRC3, OmNLRC5 and OmNLRX1...

Brucellosis is a serious zoonosis with a rapid increase in incidence across epidemic regions. Currently, there are numerous methods for diagnosing brucellosis. However, these studies often have a few defects, such as low sensitivity, poor specificity, time consuming, laborious, and even potential biological risk. To overcome these shortcomings, we have developed a rapid, sensitive and accurate diagnosis procedure for brucellosis based on the immune magnetic beads (IMB) probe and quantum dots (QDs) - staphylococcal protein A (SPA) probe...

Fumonisin B1 (FB1) is one kind of mycotoxins that has the neurotoxicity, carcinogenicity, hepatotoxicity and immunotoxicity produced by the fungus Fusarium verticillioides, which commonly infects corn and other crops and is harmful to animal and human health upon consumption of FB1-contaminated feed or food. However, the mechanism of immunotoxicity, especially the immunosuppression induced by FB1 is still unclear. The most pivotal cells in the induction of immune responses are dendritic cells (DCs). In this study, we used murine bone marrow-derived dendritic cells (BMDCs) as a model system to elucidate the effect of FB1 on the function of BMDCs through biological methods...

Glaciers accumulate organic pollutants delivered by snow. However, our understanding of the exact dynamics of organic pollutants in the snowpack relies primarily on laboratory experiments and mathematical models. To fill the gap related to the detailed field data, we have conducted observations of melting snow profiles in two locations and three different stages of melting on one High Arctic glacier, as well as in superimposed ice. We monitored the chemical concentrations of formaldehyde, phenols, short-chain carboxylic acids, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) and snow water equivalents to derive chemical loads...

Associative learning, traditionally measured with paired associate learning (PAL) tasks, has been found to predict reading ability in several languages. However, it remains unclear whether it also predicts word reading in Chinese, which is known for its ambiguous print-sound correspondences, and whether its effects are direct or indirect through the effects of other reading-related skills such as phonological awareness and rapid naming. Thus, the purpose of this study was to examine the direct and indirect effects of visual-verbal PAL on word reading in an unselected sample of Chinese children followed from the second to the third kindergarten year...

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease. Unknown triggers lead to a mainly T cell-mediated immune response targeting the liver, the main auto-antigen of which has not been identified yet. The diagnosis of AIH is based on the elevation of immunoglobulin G / hypergammaglobulinemia, detection of characteristic autoantibodies as well as a typical pattern on liver histology. Exclusion of other causes of hepatitis and response to immunosuppressive treatment support the diagnosis of AIH...
