In this work the physical, chemical and microbial properties of four locally composted green waste composts (GWCs) namely Almukhasib, Growers, Plantex, and Super along with four imported GWC (Florabella, Mikskaar, Potgrond, and Shamrock) were studied to evaluate the quality of these composts with the acceptable standards. All composts showed normal physical properties, except the bad smell from sulfur reducing bacteria in Almukhasib, light brown color Plantex and one viable weed seed in Shamrock compost. The germination indexes of the composts comparable to the standard (90%) were 100% for Mikskaar, followed by Shamrock (92%), Florabella (97), Potgrond (95%), Plantex (98%), Growers (77%), and 5% for both Super and Almukhasib. The physical and chemical properties vary considerably as follows: pH 3 - 10.5, 5.1 - 6.5 (standard 5 - 8), electrical conductivity (EC) 0.4 - 10.2 mS·cm-1, 0.8 - 1.8 mS·cm-1(standard 0.0 - 4.0 mS·cm-1), moisture content (MC%) 29% - 43.7%, 64% - 74% (standard 35% - 60%) and water holding capacity (WHC%) 92% - 200% and 400% - 800% for the locally produced and imported composts, respectively. Wide ranges in the chemical properties were expressed as ammonia concentration 512.4 - 1640.1 mg·kg-1, 459.4 - 656.5 mg·kg-1(standard -1), organic matter 17% - 67.6%, and 53.3% - 66.2% (standard 35%) for the locally composted and imported composts, respectively. The concentrations of the heavy metals (Zn, Ni, Pb, Hg, As, Cd, and Cr) were lower than the recommended levels. The average of the bacterial colony forming unit per gram of locally produced and imported composts ranged between 260 - 1740 CFU/g and 330 - 2870 CFU/g, whereas the fungal CFU were 10 - 2800 CFU/g and 27 - 1800 CFU/g, respectively. The most probable number (MPN) for coliform bacteria was 43 - 1100 CFU/g for locally produced composts, and 23 - 480 CFU/g for the imported composts. Therefore, these composts can not be used directly without effective treatment as substrate for plant growth, so

The dielectric constant and dielectric loss of Te10Ge10Se80-xSbx (x=3, 6, 12 at. pct) chalcogenide alloys were measured in the temperature range (300 to 453 K) and the frequency range (100 Hz to 100 kHz). The real dielectric constant ∈′and imaginary dielectric constant ∈' show a decrease with increasing frequency and an increase with increasing temperature. All samples display dielectric dispersion. Both ∈′ and ∈' show a Debye relaxation type. The enthalpy activation energy ΔH and activation energy WH were calculated. Cole-Cole diagram consists of an arc of semicircle shifted from the origin and its center below the real axis at high frequency

＜正＞Chronic stress elicits remarkable alterations to the structure and function of several areas of the central nervous system. It is well established that chronic stress acts as a predisposing and precipitating factor in the onset of certain forms of depression in humans. Among the variety of procedures leading to human depressive-like symptoms in animals, stress procedures take place among the well-validated models. Adenosine is an endogenous neuromodulator, which is prevalent throughout the body and interferes with neurotransmission in the peripheral and central nervous system. Adenosine is not only important in controlling cell proliferation, and as a stress signal of inflammation,but also in the function

The structure and optical properties of Cu0.1Tl2Se3 alloy was studied. X-ray analysis showed that the polycrystalline powder consists of a mixture of two phases Cu3jTlSe2 (monoclinic) and TISe (tetragonal). Chalcopyrite phase CuTISe2 can be obtained by annealing the powder at 250'C for 1 h. Thin film with a monoclinic phase of Cu3TlSe2 was obtained for the thick film (0.7 um). The optical parameters a, n, k, e' and e' and the energy gap were calculated. The thermoelectric power measurements showed that S has a positive polarity over the whole range of temperature.
