In the title compound, C(21)H(18)BrNO, both heterocyclic rings, viz. the hydro-pyridine ring and the adjacent hydro-furan ring, adopt envelope conformations. These two heterocycles make a dihedral angle of 37.3 (1)°. The dihedral angle between the hydro-pyridine and benzene rings is 69.6 (1)°. In the crystal, adjacent mol-ecules are linked by pairs of inter-molecular C-H⋯O hydrogen bonds, formi...

The prediction of pressure and output power fluctuations amplitudes on Francis turbine prototype is a challenge for hydro-equipment industry since it is subjected to guarantees to ensure smooth and reliable operation of the hydro units. The European FP7 research project Hyperbole aims to setup a methodology to transpose the pressure fluctuations induced by the cavitation vortex rope from the re...

Ambelania occidentalis is routinely used in folk medicine for treating gastrointestinal disorders, even though there have been no safety trials. We evaluated the genotoxic potential of hydro-alcoholic extracts of this plant in mice; induced DNA damage was assessed in peripheral blood leukocytes and micronucleus induction was assessed in polychromatic erythrocytes from bone marrow. The extract w...

Variable speed generator systems (VSGs) are at work in the now 600 GW installed wind power plants (parks). Also, they used as vehicular and on ground stand-alone generators. VSGs imply full kVA rating PWM converters permanent magnet (PM) or electrically excited synchronous cage rotor inductance But, to reduce cost absence of PMs a reasonable initial (weight) efficiency, fractional converter dou...

Objective: Exposure to heavy metals such as lead (Pb) results in oxidative stress induction in the male reproductive system. Herbal medicine can be utilized as antioxidant agents against oxidative stress. Quercus brantii (QB) has shown antioxidant activity in previous studies. The aim of the present study was to evaluate effects of QB hydro-alcoholic extract against Pb-induced oxidative stress ...

This article presents snow hydrology updates made to iTree-Hydro, previously called the Urban Forest Effects—Hydrology model. iTree-Hydro Version 1 was a warm climate model developed by the USDA Forest Service to provide a process-based planning tool with robust water quantity and quality predictions given data limitations common to most urban areas. Cold climate hydrology routines presented in...

BACKGROUND Diuretics are widely used in patients with chronic kidney disease (CKD). While thiazide-like diuretics limit urinary calcium excretion, loop diuretics (LD) promote calcium wasting, which might facilitate the development of secondary hyperparathyroidism (HPT2). We sought to investigate, in CKD patients not on dialysis, the influence of either hydrochlorothiazide (Hydro) or furosemide ...

Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by moving or falling water. History proves that the cost of this electricity remains constant over the year. Because of the many advantages, most of the countries now have hydropower as the source of major electricity producer. The most important advantage of hydropower is that t is gree...
