Fractionation of CIMV wheat straw lignin as an approach for promoting it interaction with isocyanates and characteristic of products obtained [PDF]

open access: yes, 2012
The reactivity of CIMV lignin fractions with MDI has been investigated in extra dry dioxane (DOX) in argon atmosphere at 25 degrees of Celsius, using FTIR spectroscopy (absorbance band at 2273 cm^-1) for monitoring the NCO group disappearance during ...

Static magnetic order in metallic K$_{0.49}$CoO$_{2}$ [PDF]

open access: yes, 2005
By means of muon spin spectroscopy, we have found that K$_{0.49}$CoO$_2$ crystals undergo successive magnetic transitions from a high-T paramagnetic state to a magnetic ordered state below 60 K and then to a second ordered state below 16 K, even though ...

Cold interactions and chemical reactions of linear polyatomic anions with alkali-metal and alkaline-earth-metal atoms

open access: yes, 2017
We consider collisional studies of linear polyatomic ions immersed in ultracold atomic gases and investigate the intermolecular interactions and chemical reactions of several molecular anions ($\mathrm{OH}^-$, $\mathrm{CN}^-$, $\mathrm{NCO}^-$, $\mathrm ...

Indels, structural variation, and recombination drive genomic diversity inPlasmodium falciparum [PDF]

open access: yes, 2016
The malaria parasite Plasmodium falciparum has a great capacity for evolutionary adaptation to evade host immunity and develop drug resistance. Current understanding of parasite evolution is impeded by the fact that a large fraction of the genome is ...

Laser Cutting of Titanium Alloy Plates: A Review of Processing, Microstructure, and Mechanical Properties

open access: yesMetals
The growing use of titanium alloys has led to the gradual replacement of traditional processing methods by laser cutting technology, making it the preferred method for processing titanium alloy plates due to its high efficiency, precision, and ...

The CO-H2 conversion factor of diffuse ISM: Bright 12CO emission also traces diffuse gas

open access: yes, 2011
We show that the XCO factor, which converts the CO luminosity into the column density of molecular hydrogen has similar values for dense, fully molecular gas and for diffuse, partially molecular gas.

Intermediate mass black holes in AGN disks II. Model predictions & observational constraints [PDF]

open access: yes, 2014
If intermediate mass black holes (IMBHs) grow efficiently in gas disks around supermassive black holes, their host active galactic nucleus (AGN) disks should exhibit myriad observational signatures.

Effect of NCO content on working principle and structural behavior of laminated polyurethane seismic bearings

open access: yesCase Studies in Construction Materials
With the increasing constraints on urban development spaces and the rapid rise in traffic flow, there is a growing demand for urban overpasses and elevated bridges that utilize less land while exhibiting superior performance.

Milk production and survival of spring-calving carryover cows in New Zealand dairy herds : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Animal Science at Massey University, Manawatu, New Zealand [PDF]

open access: yes, 2017
Non-pregnant cows are generally culled from dairy herds and replaced with two-year-old heifers. Alternatively, non-pregnant cows can be dried-off at the end of lactation, retained for one year (carried over), before being mated and returned to a milking ...

Electron Doping of Cuprates via Interfaces with Manganites [PDF]

open access: yes, 2007
The electron doping of undoped high-$T_c$ cuprates via the transfer of charge from manganites (or other oxides) using heterostructure geometries is here theoretically discussed.
