Immunohistochemical localization of adhesion molecules (CD62 and CD18) in the mammary gland of dairy cows
cattle L-selectin β2-integrin mastitis
2015/6/4
Localization of the L-selectin (CD62L) and β2-integrin (CD18) bearing cells in different tissues of the bovine mammary gland was examined. Five dairy cows of Holstein-Friesian breed in the middle of t...
Investigation Of The Orientation Dependence On Chiroptical Properties Of Single Molecules
chiral dipole emission fluorescence single molecule
2014/11/20
Optical activity is the defining property of chiral materials that is essential for characterization in biology, chemistry, and physics. While a substantial body of research has provided a strong theo...
Anti-S. aureus and anti-List. monocytogenes molecules produced by cheese-isolated lactic acid bacteria
enterocin A Enterococcus faecium lactic acid Lactobacillus plantarum Lactococcus lactis surface-bound bacteriocins
2014/3/28
Nine lactic acid bacteria from artisanal-made cheeses were investigated for their ability to inhibit Listeria monocytogenes and Staphylococcus aureus. Both extracellular and surface-bound bacteriocins...
Cavity-meidated collisionless sympathetic cooling of molecules with atoms
Cavity-meidated collisionless sympathetic molecules atoms Atomic Physics
2012/5/29
Cooling a range of molecules to ultracold temperatures (<1 mK) is a difficult but important challenge in molecular physics and chemistry. Collective cavity cooling of molecules is a promising method t...
Decoding Pure Rotational Molecular Spectra for Asymmetric Molecules
Pure Rotational Molecular Spectra Asymmetric Molecules Chemical Physics
2012/4/24
In this paper we demonstrate how asymmetric molecular rotational spectra may be introduced to students both "pictorially" and with simple formulae. It is shown that the interpretation of such spectra ...
Making the best of mixed-field orientation of polar molecules: A recipe for achieving adiabatic dynamics in an electrostatic field combined with laser pulses
mixed-field orientation of polar molecules recipe adiabatic dynamics electrostatic field laser pulses Chemical Physics
2012/4/24
We have experimentally and theoretically investigated the mixed-field orientation of rotational-state-selected OCS molecules and we achieve strong degrees of alignment and orientation. The applied mod...
Dipole-Quadrupole Theory of Surface Enhanced Infrared Absorption and Appearance of Forbidden Lines in the SEIRA Spectra of Symmetrical Molecules
Dipole-Quadrupole Theory Surface Enhanced Infrared Absorption and Appearance Forbidden Lines the SEIRA Spectra Symmetrical Molecules Optics
2012/4/20
The paper presents main aspects of the Dipole-Quadrupole theory of Surface Enhanced Infrared Absorption (SEIRA). It is pointed out the possibility of appearance of the lines, caused by totally symmetr...
Tracing the structure of asymmetric molecules from high-order harmonic generation
Tracing the structure asymmetric molecules high-order harmonic generation
2014/5/28
We investigate high-order harmonic generation (HHG) from asymmetric molecules exposed to intense laser fields. We show that the emissions of odd and even harmonics depend differently on the orientatio...

SEPIOLITE TYPES OF WATER MOLECULES DEHYDRATION PROCESS
2011/11/15
A detailed study has been made of the dehydration of sepiolite. This work, together with other studies of dehydration in vacuo and over phosphoric anhydride, rehydration of samples heated to various t...
Electron Affinities of the Early Lanthanide Monoxide Molecules
LaO CeO PrO NdO Electron affinity Photoelectron imaging Density func-tional calculation Ligand field theory
2012/4/5
The photoelectron imagings of LaO-, CeO-, PrO-, and NdO- at 1064 nm are reported. The well resolved photoelectron spectra allow the electron a±nities to be determined as 0.99(1) eV for LaO, 1.00(1) eV...

The structure-property characteristics of a series of newly synthesized intramolecular charge-transfer (ICT) compounds, single-branch monomer with triphenylmethane as electron donor and 2,1,3-benzothi...
Preparation, Characterization and Properties of Crosslinked Chitosan/Palygorskite Resin with Tannic Acid as Template Molecules
Chitosan (CS) Palygorskite Resin Tannic Acid Template
2011/11/14
The chitosan/palygorskite resins with tannic acid (TA) as template molecules (CPRT) were prepared by emulsion cross-linking technology. Palygorskite (PAL), a kind of natural one-dimensional clay, work...
The efficiency of cavity sideband cooling of trapped molecules is theoretically investigated for the case where the IR transition between two rovibrational states is used as a cycling transition. The ...
The first molecules detected at infrared wavelengths in the ejecta of a Type II supernova, namely SN1987A, consisted of CO and SiO. Since then, confirmation of the formation of these two species in se...
