What are trans fatty acids (TFA)? Fatty acids found in foods can be saturated (SFA, no double bonds), monounsaturated (MUFA, 1 double bond) or polyunsaturated (PUFA , 2 or more double bonds). The double bonds provide rigidity to the molecule and result in specific molecular configurations. Naturally occurring fatty acids in foods usually have the cis configuration, i.e. the hydrogen atoms with ...

Several nonexistence results on generalized bent functions f : Zn 2 → Zm presented by using some knowledge on cyclotomic number fields and their imaginary quadratic subfields.

Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...

BACKGROUND This study sought to determine safe ranges of oblique angle, skin entry point and needle length by reviewing computed tomography (CT) scans and to evaluate the usefulness of a bent tip needle during celiac plexus block (CPB). METHODS CT scans of 60 CPB patients were reviewed. Image of the uppermost margin of L2 vertebral body was used to measure the minimal and maximal oblique angl...

Structural instabilities of Cd2Nb2O7 have been explored by all-electron ab initio calculations in the framework of density-functional theory. The calculated phonon-dispersion curve of the cubic high-temperature phase displays several modes with imaginary frequencies. A distortion according to a T1u mode at the point leads to the energetically most favorable configuration. The resulting structur...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

Extending a computation which appeared recently in [1], we compute the transmission and reflection coefficients for massless uncharged scalars and gravitational waves scattered by d ≥ 4 Schwarzschild or d = 4 Reissner-Nordstrøm black holes, in the limit of large imaginary frequencies. The transmission coefficient has an interpretation as the “greybody factor” which determines the spectrum of Ha...

Cyclopentadienylmolybdenum(II) tricarbonyl dimer exists in two different equilibrium conformations: trans and gauche. Ultrafast photoexcitation in the ultraviolet cleaves the Mo-Mo bond, permitting observation of the subsequent geminate rebinding reaction (t(rebinding) = 31.6 ps) by monitoring infrared bleach recoveries at frequencies corresponding to the CO stretches of the trans and gauche is...
