Adiabatic TOCSY for C,C and H,H J-transfer.

Adiabatic pulses have been widely used for broadband decoupling and spin inversion at high magnetic fields. In this paper we propose adiabatic pulses and supercycles that can be used at high magnetic fields like 800 or 900 MHz to obtain broadband TOCSY sequences with C,C or H,H J-transfer. The new mixing sequences are equal or even superior to the well known DIPSI-2,3 experiments with respect t...

Should the fact that a criminal off ender lives in a society that fails to give him what he ‘deserves’ in terms of economic or political or social rights aff ect the determination of what he ‘deserves’ from that society in terms of punishment? More generally, to what extent is the fairness of a given system of retributive justice dependent on the fairness of the system of distributive or socioe...

Effect of temperature on the development of C - S - H during early hydration of C 3 S

It is known that accelerating or retarding hydration of OPC by temperature has consequences on the final properties of concrete, the lower the temperature the higher the final compressive strength. It seems that this effect is related to the properties of the hydration layer formed at early age. Early hydration of C3S has then been studied at temperature ranging from 5 to 45°C in isothermal con...

Creep of a C-S-H gel: a micromechanical approach.

Both clays and calcium silicate hydrates(the main hydration products of Portland cements) exhibit a microstructure made up of lamellar particles. The microscopic mechanism responsible for the macroscopic creep of such materials is often described as the relative sliding of the sheets. This paper proposes a micromechanical approach to estimate the macroscopic creep behavior rising from this micr...
