Biomass can be utilized to produce bio-oil, a promising alternative energy source for the limited crude oil. There are mainly two processes involved in the conversion of biomass to bio-oil: flash pyrolysis and hydrothermal liquefaction. The cost of bio-oil production from biomass is relatively high based on current technologies, and the main challenges are the low yield and poor bio-oil quality...

Bio-silica represents the main mineral component of the sponge skeletal elements (siliceous spicules), while bio-polyphosphate (bio-polyP), a multifunctional polymer existing in microorganisms and animals acts, among others, as reinforcement for pores in cell membranes. These natural inorganic bio-polymers, which can be readily prepared, either by recombinant enzymes (bio-silica and bio-polyP) ...

The current aim of our research work is to isolate bio-polymer from fresh rhizomes of Zingiber officinale & to evaluate its retardibility by formulating microdwarfs containing nimesulide as a model drug. The bio-material was isolated by a simplified method. Six different bio-micro dwarf formulations were prepared using isolated bio-material as a retardant. The formulated microcapsules were eval...

In the paper will be presented a safety and security system based on fingerprint technology. The results suggest a new scenario where the new cars can use a fingerprint sensor integrated in car handle to allow access and in the dashboard as starter button. Introduction One of the most relevant question in the security world is how identify and recognize people not only in some protected areas w...

in vitro expansion of mesenchymal stem cell (mscs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. on the other hand, some studies have indicated that bio (6-bromoindirubin-3-oxime) possesses mitogenic effects on cell culture. the objective of the present study was to examine the effect of bio on in vitro expansion and chondrogenic di...

Because in the dog, the gastric fundus contains the largest amount of glucagon immunoreactivity (IRG), the IRG of mucosal scrapes of 105 canine stomachs was extracted by acid-ethanol and then precipitated by ether-ethanol. The IRG recovered was measured by antisera 30K, specific for glucagon and K-4023, which cross-reacts with glucagon-like immunoreactivity. Extracts of mucosa of stomach fundus...

Electrochemical impedance spectroscopy (EIS) was used to study the behavior of a microbial fuel cell (MFC) during initial biofilm growth in an acetate-fed, two-chamber MFC system with ferricyanide in the cathode. EIS experiments were performed both on the full cell (between cathode and anode) as well as on individual electrodes. The Nyquist plots of the EIS data were fitted with an equivalent e...

This short text is the second in a series of articles from the recently established “Bio-Objects” research network supported by the European Commission’s Cooperation in Science and Technology (COST) program (1). Here we explore in more detail the ways in which we understand the boundaries of bio-objects determined through a “bio-objectification” process wherein life-forms or living entities are...

The cardiac microenvironment includes cardiomyocytes, fibroblasts and macrophages, which regulate remodeling after myocardial infarction (MI). Targeting this microenvironment is a novel therapeutic approach for MI. We found that the natural compound derivative, BIO ((2'Z,3'E)-6-Bromoindirubin-3'-oxime) modulated the cardiac microenvironment to exert a therapeutic effect on MI. Using a series of...
