Metamaterials, i.e. artificial materials with properties not found in nature (Caloz & Itoh,
2006; Marqués et al., 2008), have gained a lot of attention in the past decade. The
virtually unlimited freedom in tailoring their constitutive parameters created hopes for
the realization of unique devices, such as subwavelength lenses and invisibility cloaks,
which were essentially impossible to achieve with classical materials.
These criteria are
classified into its safety profile, performance within the GI tract and technological
aspects of its development. The criteria are further dependent on the specific purpose
of the strain and on the location for the expression of the specific property. With
regards to safety, the probiotic strain must be of human origin, isolated from the
gastrointestinal tract (GIT) of healthy individuals.
This Volume contains both the invited lectures and the contributions to the
Workshop on The Physics of Excited Nucleons (NSTAR 2001), which was
held at the Johannes Gutenberg-Universitat Mainz, March 7-10, 2001. The
origin of this workshop series goes back to the conference on Excited Baryons,
which was initiated and organized by our late friend Nimai Mukhopadhyay
and his colleagues at the Rensselaer Polytechnic Institute in 1988.

In this chapter, you will learn to: Know that photosynthesis is broken up into two parts: Light rxns and carbon fixation, know the names of the major components of the chloroplast and the functions and properties of these components, know how light energy is converted to chemical energy, understand how a photon can excite an electron to a high energy orbital, know what happens when the electron returns to ground state,...
The catalytic activity of phenylalanine hydroxylase (PAH,
phenylalanine 4-monooxygenase EC 220.127.116.11) is regulated
by three main mechanisms, i.e. substrate (L-phenylalanine,
L-Phe) activation, pterin cofactor inhibition and phos-phorylation of a single serine (Ser16) residue.To address the
molecular basis for the inhibition by the natural cofactor
(6R)-L-erythro-5,6,7,8-tetrahydrobiopterin, its effects on the
recombinant tetrameric human enzyme (wt-hPAH) was
studied using three different conformational probes, i.e.
The purified membrane-bound [NiFe]-hydrogenase from
Methanosarcina barkeriwas studied with electron para-magnetic resonance (EPR) focusing on the properties of the
iron–sulphur clusters. TheEPRspectra showed signals from
threedifferent [4Fe)4S] clusters.Twoof the clusters couldbe
reduced under 101 kPa of H2, whereas the third cluster was
only partially reduced.
The theoretical analysis of MTSM has been developed to model and simulate the signature of the sensor responses at harmonic frequencies. The signatures of the evaporation- induced deposition processes were investigated by studying the effect of the thickness and stiffness of the medium.
