BACKGROUND For decades, copper sulphide has been renowned as the superior optical and semiconductor materials. Its potential applications can be ranged from solar cells, lithium-ion batteries, sensors, and catalyst systems. The synthesis methodologies of copper sulphide with different controlled morphology have been widely explored in the literature. Nevertheless, the understanding on the forma...

pollution sources into the water, the necessity of qualitative studies of water resources is one of the most important new challenges for mankind in almost every parts of the world. dissolved oxygen (do) and biochemical oxygen demand (bod) are among parameters of water quality indexes which are considered as water pollution indexes. in the present research, do and bod of dez river basin water (...

ABSTRACT We constrain the matter density Ωm and amplitude of fluctuations σ8 within ΛCDM cosmological model with shear peak statistics angular convergence power spectra using mass maps constructed from first three years data Dark Energy Survey (DES Y3). use tomographic statistics, including cross-peaks: counts calculated on created by taking a harmonic space product two redshift bins. Our analy...

In the biotechnological gas desulfurization process, dissolved sulfide is oxidized into predominantly elemental sulfur (S8) by oxidizing bacteria (SOB) under strict oxygen limited conditions. An online measurement of oxidation reduction potential (ORP) used to control O2 supply bioreactor maximize selectivity for S8 formation and minimize unwanted sulfate formation. While ORP in considered be a...

BACKGROUND Salbutamol exhibits partial agonist/antagonist activity at airway beta 2 receptors in vitro in that it attenuates the bronchorelaxant effect of the full agonist isoprenaline. The aim of the present study was to characterise the partial beta 2 agonist/antagonist activity of salbutamol in vivo during supine rest and exercise, in states of low and high adrenergic tone. METHODS Eight n...

Yield per unit area increased rapidly to a maximum as the number of stools increased, and either remained relatively constant or declined slightly with higher stool densities, depending upon the particular component of yield. The results imply that under favourable growing conditions, maximum yield per unit area can be achieved with relatively low stool populations. There is considerable potent...

The SHARP/NTT stellar proper motion data now cover an interval from 1992 to 2000 and allow us to determine orbital accelerations for some of the most central stars. We confirm the stellar acceleration measurements obtained by Ghez et al. (2000) with NIRC at the Keck telescope. Our analysis differs in 3 main points from that of Ghez et al.: 1) We combine the high precision but shorter time scale...
