Aromatic organoarsenicals roxarsone (ROX) and p-arsanilic acid (ASA) are typical emerging contaminants, and usually as an additive to poultry feed in order to control coccidial intestinal parasites and improve feed efficiency. ^[1] ROX and ASA tend to be discharged by poultry instead of remaining in animal body. ^[2] Aromatic organoarsenicals can be degraded by …

Magnetic nano-particles CuFe₂O₄ were successful manufactured from industrial sludge by combination of acid leaching, chemical exchange, and ferrite process. For the first time these recycled nano-particles were used as adsorbent to investigate the kinetics and thermodynamics for adsorption of Cd in aqueous solutions. These experimental results showed that Cd²⁺ …

Pain often accompanies cancer and has a major impact on the survival and quality of life for cancer patients. It is estimated that 75%-90% of patients with metastatic or advanced stage cancer experience significant cancer-induced pain. Although various complementary therapies, including radiotherapy, chemotherapy and treatment with bisphosphonates and analgesics, have been used to treat bone …

The grid-connected AC module is an alternative solution in photovoltaic (PV) generation systems. It combines a PV panel and a micro-inverter connected to grid. The use of a high step-up converter is essential for the grid-connected microinverter because the input voltage is about 15 V to 40 V for a single PV panel. The proposed converter employs a Zeta converter and a coupled inductor, without …
