hydro-forming is a fabrication process that uses a fluid medium to form a piece by using high internal pressure. in tube hydro-forming, a tubular blank is placed between two dies, sealed and pressurized water injected, deforming the tube walls in the cavity form of the dies. exist several typical hydro-forming processes such as t- shapes, cross-shapes and y- shapes. successful hydro-forming dep...

Over the last decade or so, a number of jurisdictions throughout the developed and developing world have embarked upon major competitively oriented restructurings of their electricity industries. Ontario has recently joined this list. Historically, Ontario Hydro has been the largest state-owned enterprise in Canada, having been created by the government of Ontario in 1906 initially to construct...

BACKGROUND Malaria is a major public health problem in the world which is responsible for death of millions particularly in sub-Saharan Africa. Today, the control of malaria has become gradually more complex due to the spread of drug-resistant parasites. Medicinal plants are the unquestionable source of effective antimalarials. The present study aimed to evaluate antiplasmodial activity and acu...

abstract introduction the main function of the fibrinolytic system is to dissolve fibrin clots in circulation. this system is composed of inactive precursor plasminogen which can be converted into plasmin by the proteolytic enzymes like tissue-type plasminogen activator (tpa). fibrinolytic properties can be found in a variety of medicine plants and they could effectively prevent cardiovascular ...

the physiological process of germination depends on several environmental factors such as temperature, water potential, light, nutrients and smoke. water and temperature are determinant factors for seed germination. both factors can, separately or jointly, affect the germination percentage and germination rate. the effect of temperature on germination and water potential on germination canoften...

In the title compound [Ca(C(12)H(25)O(4)S)(2)](n), the unique Ca(II) ion lies on an inversion center and is coordinated in a slightly distorted octa-hedral environment by six O atoms from dodecyl sulfate anions. The crystal structure is based on hydro-carbon (dodecyl sulfate) layers which sandwich the Ca(II) ions. Within the layers, the hydro-carbon zigzag chains are parallel to one another and...

In the title compound, tetra-hydro-seselin, C14H16O3, a pyran-ocoumarin [systematic name: 8,8-dimethyl-3,4,9,10-tetra-hydro-2H,8H-pyrano[2,3-f]chromen-2-one] obtained from the hydrogenation of seselin in the presence of Pd/C in MeOH at room temperature, the dihedral angle between the central benzene ring and the best planes of the outer fused ring systems are 6.20 (7) and 10.02 (8)°. In the cry...

In the title compound, C29H37NO3 {systematic name: (E)-1-(4-meth-oxy-phen-yl)ethanone O-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthrene-1-carbon-yl]oxime}, a new derivative of de-hydro-abietic acid, the two cyclo-hexane rings exhibit a trans-ring junction and are in chair and half-chair conformations. The C=N double bond exhibits an E conformation.

In the title compound, C15H18N2O3S, the hydro-pyrimidine ring adopts a sofa conformation with the methine C atom as the flap. The benzene ring is almost perpendicular to the mean plane of the hydro-pyrimidine ring, making a dihedral angle of 85.51 (8)°, and the meth-oxy O atom lies over the centre of the pyrimidine ring. In the crystal, weak N-H⋯S inter-actions form a zigzag chain running along...
