The use of cost effective solvents may be necessary to store wood pyrolysis bio-oil in order to stabilize and control its viscosity, but this part of the production system has not been explored. Conversely, any rise in viscosity during storage, that would occur without a solvent, will add variance to the production system and render it cost ineffective. The purpose of this study was to modify b...

BACKGROUND There have been many studies that utilize the bio-impedance measurement method to analyze the movements of the upper and lower limbs. A fixed electrical current flows into the limbs through four standard disposable electrodes in this method. The current flows in the muscles and blood vessels, which have relatively low resistivity levels in the human body. This method is used to measu...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

background: hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. on the other hand, mesenchymal stem cells (mscs) are regarded as potent cells with a property of cartilage regeneration. we aimed to optimize marrow-derived msc chondrogenic culture using a small bioactive molecule referred to as bio. methods: mscs from the ma...

The quest to 'forward-engineer' and fabricate biological machines remains a grand challenge. Towards this end, we have fabricated locomotive "bio-bots" from hydrogels and cardiomyocytes using a 3D printer. The multi-material bio-bot consisted of a 'biological bimorph' cantilever structure as the actuator to power the bio-bot, and a base structure to define the asymmetric shape for locomotion. T...

Bamboo is a board group of over 1250 species, belongs to grass family. It may have a potential as bio energy for production of biomass drive fuel. As the energy consumption rate increases by every year and about 80% of world’s energy depends on petroleum. Bio fuel may be an alternative source of energy up to the future. Previously ionic liquids have shown good solubility of lignocelluloses mass...

Recently, significant advances have occurred in the development of phosphors for bio hybrid light-emitting diodes (Bio-HLEDs), which have created brighter, metal-free, rare-earth phosphor-free, eco-friendly, and cost-competitive features for visible light emission. Here, we demonstrate an original approach using bioinspired phosphors in Bio-HLEDs based on natural deoxyribonucleic acid (DNA)-cur...

This paper proposes an efficient watermark generation method for audio copyright protection and digital right management. It proposes a method of generating pseudorandom sequences based on iris image templates. These biometric generated sequences (bio-keys) are found to be unique for distinct identification purposes. These bio-keys are used as the watermark for audio signals. The correlation of...
