A Clear Solution for Dirty Water
Serum levels of alpha1-antitrypsin (alAT) were measured by radial immunodiffusion and phenotypes were determined by electrofocusing in acrylamide gel in 39 patients with hepatocellular carcinoma (HCC) positive for serum hepatitis B surface antigen (HBsAg), 41 patients with HCC negative for serum HBsAg, and 160 ageand sex-matched hospital controls. There was no difference between the control ser...
متن کاملWater: a clear and present danger.
Clean drinking water. It is something that the public has pretty much taken for granted for the past hundred years. The public has little idea and, perhaps understandably, little interest, in the many people and agencies struggling daily to ensure that drinking water remains uncontaminated. But our environment is changing, new pathogens are emerging, drinking water systems are aging, and govern...
متن کاملQUIC & DIRTY: A Quadratic Approximation Approach for Dirty Statistical Models
In this paper, we develop a family of algorithms for optimizing “superpositionstructured” or “dirty” statistical estimators for high-dimensional problems involving the minimization of the sum of a smooth loss function with a hybrid regularization. Most of the current approaches are first-order methods, including proximal gradient or Alternating Direction Method of Multipliers (ADMM). We propose...
متن کاملControlled Crystallization of LTA Zeolitic Nanoparticles from a Clear Solution Using Organic Template
LTA Zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, </e...
متن کاملEnvironmental education as a solution tool for the prevention of water pollution
Water is the origin of life. 3/4 of the Earth's surface is covered by water and all living things must have water to survive. Life without water can not be considered. Despite this, of all living things only humans exploit, waste and pollute this vital natural resource. Raising awareness of the people on this issue is of great importance. At this point, environmental education is a key concept....
