The demand for efficient utilization of biomass induces a detailed analysis of the fundamental chemical structures of biomass, especially the complex structures of lignin polymers, which have long been recognized for their negative impact on biorefinery. Traditionally, it has been attempted to reveal the complicated and heterogeneous structure of lignin by a series of chemical analyses, such as...

MgB2 wires, tapes and bulk samples produced within the EU-funded HIPERMAG project have been studied by a combination of X-ray diffraction and electron microscopy. The reaction layers forming at the interface between the ceramic core and Fe or Ni sheaths can be studied with both methods. The complementary techniques enable to study both the microstructure and the formation kinetics of the interf...

Defects during Plasma Transfer Arc (PTA) beam fusion additive manufacturing (AM) processing of Ti-6Al-4V, including lack of fusion, porosity variations, and solidification cracking, have been monitored using near infrared (1.62 μm) imagery at 300 Hz, 300 μm spatial resolution and melt pool sizes of greater than 12μ. The temperature evolution exhibits a periodic temperature modulation of more th...

Xenopus model. It provides wild-type, transgenic and mutant frogs to research labs at cost and can now also supply oocytes, embryos and frozen sperm. All of the GA animals are quality controlled to ensure that their offspring have the expected phenotype. In addition to these animal resources EXRC is gathering insitu hybridisation probes, relevant antibodies and expression clones from labs; agai...

Technological improvements over the past decade have led to the widespread use of autonomous surface and underwater vehicles for data collection in marine environmental sensing and modeling in coastal environments. However, these vehicles and their sensors still have limitations, especially when tasked with observing highly dynamic or transient processes. We investigate the application of a sma...

Dealing with high-temperature properties and brittleness is always one of the hot topics in field ceramic materials. Extensive research has been carried out for it Si3N4-SiC composites are most promising composites. In this study, impact Si3N4 BN reinforcement on microstructure physio-mechanical SiC-based were explored. Two sets composites, including BN-Si3N4-SiC aided Al2O3, fabricated using n...

the proposition that natural areas need protection from the destructive actions of people iswidely accepted. this paper examines iran’s e-society attitudes and capital towards biodiversity conservationand evaluates economically iran’s national parks (nps). 2,121 respondents answered an online questionnaire conducted in summer 2012. the majority of respondents had visited one of iran’s nps. almo...

according to the non-physical aspects of conservation in the world today and intangible effects were considered serious. conservation process, but help to understand the purpose and effect of not reading, but perception is a matter of epistemological roots in philosophy and  in modern philosophy the process of understanding a monument-art conservation in connection with the audience is importan...
