Culturing microalgae using natural sunlight is an effective way to reduce the cost of microalgae-based biodiesel production. In order to evaluate the feasibility of culturing Chlorella zofingiensis outdoors for biodiesel production, effects of nitrogen limitation and initial cell concentration on growth and lipid accumulation of this alga were investigated(More)
Preliminary findings indicate that PprI is a regulatory protein that stimulates transcription and translation of recA and other DNA repair genes in response to DNA damage in the extremely radioresistant bacterium Deinococcus radiodurans. To define the repertoire of proteins regulated by PprI and investigate the in vivo regulatory mechanism of PprI in(More)
To evaluate the potential of the green agla Chlorella zofingiensis as a feedstock for biodiesel production, the effects of nitrogen and phosphate on lipid accumulation and growth of C. zofingiensis were studied. The maximum specific growth rate (μ(max)) reached 2.15 day⁻¹ when the concentration of NaNO₃ and K₂HPO₄·3H₂O was 1.0 g L⁻¹ and 0.01 g L⁻¹,(More)
BACKGROUND Anaerobic digestion has been widely applied to treat the waste activated sludge from biological wastewater treatment and produce methane for biofuel, which has been one of the most efficient solutions to both energy crisis and environmental pollution challenges. Anaerobic digestion sludge contains highly complex microbial communities, which play(More)
Massively Multiplayer Online Games (MMOGs) are increasing in both popularity and scale, and while classical Client/Server architectures convey some benefits , they suffer from significant technical and commercial drawbacks. This realisation has sparked intensive research interest in adapting MMOGs to Peer-to-Peer (P2P) architectures. This paper articulates(More)
Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility, affecting 5-10% of females of reproductive age. Currently, little is known about the changes in whole proteins between PCOS and normal ovaries. In the present study, a proteomic approach comprised two-dimensional gel electrophoresis (2DE) analysis and mass spectroscopy was(More)
There is great potential to use free nitrous acid (FNA/HNO2), the protonated form of nitrite, as an antimicrobial agent due to its bacteriostatic and bactericidal effects on a range of microorganisms. Here, we determine the effects of FNA on the opportunistic pathogen Pseudomonas aeruginosa PAO1, a well-studied denitrifier capable of nitrate/nitrite(More)
We present a cloud-based healthcare system that integrates a formal care system (DACAR) with an informal care system (Microsoft Health Vault). The system provides high levels of security and privacy within a cloud environment, enabling sharing of both health records and the access rights, along the patient pathway. We also define a case study that can help(More)
The use of digital technologies in providing health care services is collectively known as eHealth. Considerable progress has been made in the development of eHealth services, but concerns over service integration, large scale deployment, and security, integrity and confidentiality of sensitive medical data still need to be addressed. This paper presents a(More)
