Zeolites containing Zn in their frameworks are promising materials for ion-exchange and catalysis because of their unique ion-exchange capabilities and characteristic Lewis acidity. However, expensive organic compounds often required in their synthesis can prevent their practical uses. Here, a facile organic-free synthesis route for new zincoaluminosilicate zeolites having MOR topology, in whic...

We present the re dot structures with GaA source molecular bea emission wavelength ~170nm was observed in place of GaAs. How barrier layer thickness in luminescence intens GaInNAs dots. Lasers active layer were fa continuous-wave lasing Lasing occurs via the threshold current dens output power of 16mW better than previously r dot system.

The present paper deals with the concept of antiresonance in multiple cracked beams and application for multi-crack identification. First, governing equations antiresonant frequency are conducted used both computing frequencies versus crack parameters measuring-loading colocation identifying cracks by measured frequencies. Then, a procedure is proposed identification cantilever beam based on so...

paddy de-awning using a de-awner increases the uniformity and flow rate of paddy grains through the orifices of hoppers, bucket elevators and chutes. in this study the effects of paddy variety, rotational blade speed and moisture content on performance of a prototype de-awner machine were investigated. the experiment was conducted in a factorial design with three factors, variety (hashemi and b...

BACKGROUND Olea africana leaves are used by Bapedi people to treat different ailments. The use of these leaves is not validated, therefore the aim of this study is to validate antimicrobial properties of this plant. METHODS The ground leaves were extracted using solvents of varying polarity (hexane, chloroform, dichloromethane (DCM), ethyl acetate, acetone, ethanol, methanol, butanol and wate...

BACKGROUND Controversy persists regarding the role of Notch signaling in myelopoiesis. We have used genetic approaches, employing two Notch zebrafish mutants deadly seven (DES) and beamter (BEA) with disrupted function of notch1a and deltaC, respectively, and Notch1a morphants to analyze the development of leukocyte populations in embryonic and mature fish. DESIGN AND METHODS Myelomonocytes w...

All the industry and I-O data come from the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce. Employment, value added and relative price indexes come from the Annual Industry Accounts, according to the December 2010 release; final uses price indexes come from the National Income and Product Accounts (NIPA) tables. The I-O data for years 1947, 1958, 1963, 1967, 1972, 1977, 19...

This work is focused on the application of Cu-containing zeolites as potential environmental sensors for monitoring carbon monoxide. A number commercial with different structural properties (NaX, NaY, MOR, FER, BEA and ZSM-5) were modified using CuSO4, Cu(NO3)2 Cu(OAc)2 solutions copper sources to prepare Cu+-containing zeolites, since Cu+ forms stable complexes CO at room temperature that can ...
