the heterogeneous photo-fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. the photocatalyst has been prepared by coprecipitation method. the rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. it has been observed thatphotocatalytic degradation follows pseudo first order kinetics. the effect of various param...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

The theory of bargaining as formulated by Nash (1950, 1953) has developed along two routes. One is axiomatic (e.g., Nash 1950; Kalai and Smorodinsky 1975; Roemer 1988). Here, the negotiation process underlying the bargaining is only implicit. The idea is to try to characterize the negotiated outcome (the solution) through a set of axioms without formally modeling the process. The advantages of ...

Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...

Repeat photography, the process of locating camera position an old photo and taking a new from this position, is utilized to protect our natural heritage, by measuring landscape changes between image, conserve recover architectural archaeological observing images taken before, during, after conservation efforts or destructive events. Most importantly, repeat photography—in short, rephotography—...

Protein tyrosine kinase inhibitors are currently an important drug class in the treatment of leukemia. They represent targeted cancer therapy and have become the treatment of choice in chronic myeloid leukemia. Tyrosine kinases are enzymes expressed in multiple tissues and are involved in several signaling pathways influencing cellular growth. Below we describe a patient who developed an unusua...

Automation of non-destructive testing (NDT) of engineering components and structures represents one of the strategic objectives of many industries. It enables increases in accuracy, precision and speed of inspection while reducing production time and associated labour costs in contrast to manual inspection. The use of robots can provide additional flexibility and autonomy to automated NDT. Auto...

INTRODUCTION Authors report their clinical experience in managing a 46-year-old male patient with long lasting nose breathing difficulties caused by nasal obstruction due to a large bilateral tumor masses in both nasal cavities. CASE OUTLINE Physical examination, laboratory and biochemistry analyses, as well as computed tomography showed an inhomogeneous soft-tissue tumor mass completely fill...
