background: since organophosphorus pesticides are widely used for industry and insect control in agricultural crops, their fate in the environment is very important. pesticide contamination of surface water has been recog­nized as a major contaminant in world because of their potential toxicity towards human and animals. the objec­tive of this research was to investigate the influence of variou...

In [L1] the author introduced the canonical basis for the plus part of a quantized enveloping algebra of type A,D or E. (The same method applies for nonsimplylaced types, see [L3, 12.1].) Another approach to the canonical basis was later found in [Ka]. In [L1] we have also found that the set parametrizing the canonical basis has a natural piecewise linear structure that is, a collection of bije...

A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...

The Indonesian government has allocated the 3.3-3.4 GHz band, which is adjacent to the extended Cband 3.4-3.7 GHz, for Broadband Wireless Access (BWA) services. The country has been using the extended C-band for Fixed Satellite Service (FSS). This research shows the interference potential between the two systems if an adjacent band is allocated for them. Using a clutter loss of 10 dB and site s...

Due to the light excitation, the valence band electron of the copper (I) sulfide quantum dot transfer to the conduction band and act as a scavenger of the terminal proton of the alkyne in the presence of organic azide with the formation of 1,4-disubstituted 1,2,3-triazoles, where the copper(I) species of Cu2S act as a catalyst for the reaction. The above cycloaddition reaction between alkyne an...

In this paper, we propose a novel reception/transmission scheme for half-duplex base stations (BSs). In particular, we propose a half-duplex BS that employes in-band uplink-receptions from user 1 and downlink-transmissions to user 2, which occur in different time slots. Furthermore, we propose optimal adaptive scheduling of the in-band uplink-receptions and downlink-transmissions of the BS such...
