Determinants of Marketability for Organic Biomass Liquid Fertilizer from Human Waste in Da Nang City, Vietnam

Production of Silicon Carbide Liquid Fertilizer by Hydrothermal Carbonization Processes from Silicon Containing Agricultural Waste Biomass

Wastes from agriculture or sewage systems have several properties, such as huge volume, high humidity, and high organic composition. According to past studies, sugarcane extract, peanut shells and rice husks have high silicon content. Chemical conversion of biomass feedstock will enhance usage and provide value to agricultural waste. In this research, we applied hydrothermal carbonization to co...

Prevalence of Cervical Infection and Genotype Distribution of Human Papilloma Virus Among Females in Da Nang, Vietnam.

AIM The goal of the present study was to determine the prevalence and distribution of high-risk human papilloma virus (HPV) genotypes in women from two districts in and around Da Nang city, Vietnam. MATERIALS AND METHODS All participants were randomly selected, 200 from the Hai Chau district and 200 from the Son Tra district. The detection and genotyping of HPV were performed by real-time pol...

Increasing Tuberculosis Notification Rates Among Young Adults are Not Associated with Migration in Da Nang, Vietnam

Tuberculosis (TB) case notification rates in Vietnam have stabilized since 2000, but in 2007 were increasing among young adults. The emerging HIV epidemic only partly explains this increase. Other factors are probably involved. We aimed to assess whether rural-to-urban migration is such a factor. We conducted a case-control study at district TB units (DTUs) in Da Nang province, Vietnam, recruit...

Biotechnology for aerobic conversion of food waste into organic fertilizer.

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...
