Process Selection Considerations
Selection of an activated-sludge process for BOD removal and nitrification is a function of many considerations including specific site constraints, compatibility with the existing process, compatibility with existing equipment, present and future treatment needs, level of capability of the operating staff, capital costs, and operating cost.

We cover the meaning of cancer targeting, and how to target cancer. Nowadays, there are many not only drugs but also treatments for cancer treatment, but they have some problems.
1. Chemical-based Anticancer drugs
These chemical-based drugs are systemic drug. Therefore, normal cells are also regarded as cancer cells and become treated. Normal cells are attacked by chemical-drug, a
treatment currently receive it in the developing world.
Less than half of infected persons are eligible fortreatment based on current guidelines(only eligible at advanced stages of diseases)
Treatment must be administered for lifetime and does not cure infection
Treatment regimens are complex, toxic, and expensive.
For every new person started on treatment in 2006, approximately 6 new infe

One example can be found in the area of water use and purification, where GE scientists are investigating new membrane materials and innovative advanced separation technologies. These allow for further treatment
for solving the problem of biofuel production, and it can be used not only for biodiesel production but also for bioethanol production. Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-tr

According to a 'threat paper' on Kuwait produced in secret by the UK Atomic Energy Authority and subsequently leaked, 50 tonnes of DU inhaled could cause up to half a million additional cancer deaths over several decades, a calculat
