25. Development of an experimental model of neutrophilic pulmonary response induction in mice
BACKGROUND: Several lung diseases are characterized by a predominantly neutrophilic inflammation. A better understanding of the mechanisms of action of some drugs on the airway inflammation of such diseases may bring advances to the treatment. OBJECTIVE: To develop a method to induce pulmonary neutrophilic response in mice, without active infection. METHODS:

26. Surface instability and dislocation nucleation in strained epitaxial layers
We have studied numerically the stability and defect nucleation in epitaxial layers on a substrate with lattice mismatch. Stress relaxation and energy barriers for misfit dislocation nucleation are estimated using modern methods for saddle point search based on a combination of activation with local repulsive potential and the Nudged Elastic Band method. Str

27. Modelos hibridos de colunas de destilação
Techniques like online process optimization and model predictive control require fast simulations of the process models used. However, in some cases the process models are very complex or have a high dimension. In these cases acceleration techniques that include order reduction and model simplification can be used to obtain fast enough simulations. Distillat

28. Proposta e implementação de um sistema de processamento paralelo para dinâmica molecular. / Proposal and implementation of a parallel processing system for molecular dynamics.
A method for parallelization of molecular dynamics simulations in distributed memory machines operating under the message-passing paradigm is proposed. Even though the analysis and implementation presented in this work were primarily restricted to the system model known as microcanonical emsemble of Lennard--Jones particles. the obtained system can easily be

29. The doctor-patient relationship and euthanasia
The author offers grounds for preferring a `fiduciary' model of the doctor-patient relationship to either an `authoritative' or a `contractual' model. Within this framework he suggests that certain acts of euthanasia could be accommodated not in any way as duties, but as supererogatory acts of kindness to the patient.

30. Cold fusion in metals
A simple model of a metal containing deuterons is considered. The example of palladium is treated in detail. It is shown that the effect of screening of Coulomb fields by conduction electrons is sufficient to allow deuteron pairs to fuse at rates of 10-30 sec-1, seven orders of magnitude smaller than those reported by Jones et al. [Jones, S. E., Palmer, E. P

31. Estimation of the Transport and Carboxylation Components of the Intracellular Limitation to Leaf Photosynthesis
A model is presented which enables gas exchange data to be used to partition the intracellular resistance to leaf photosynthesis into carboxylation and transport components. A basic assumption is that the over-all kinetics of the carboxylation reaction fit the Michaelis-Menten equation.

32. The multiscale coarse-graining method. IV. Transferring coarse-grained potentials between temperatures
This work develops a method for the construction of multiscale coarse-grained (MS-CG) force fields at different temperatures based on available atomistic data at a given reference temperature. The validity of this theory is demonstrated numerically by applying it to construct MS-CG models of the Lennard-Jones liquid and simple point charge water model system

33. P/NP, and the quantum field computer
The central problem in computer science is the conjecture that two complexity classes, P (polynomial time) and NP (nondeterministic polynomial time—roughly those decision problems for which a proposed solution can be checked in polynomial time), are distinct in the standard Turing model of computation: P ≠ NP. As a generality, we propose that each physic

34. Plasmalemma Redox Activity in the Diatom Thalassiosira1: A Possible Role for Nitrate Reductase
Plasmalemma redox activity in the diatom Thalassiosira is competitively inhibited by antiserum prepared against algal nitrate reductase (NR), and fluorescent labeling experiments reveal the binding of NR antiserum to the cell surface. Furthermore, the external electron acceptor Cu bathophenanthroline disulfonate causes immediate inhibition of intracellular p

35. Clustered repeat sequences in the genome of Epstein Barr virus.
The genome of Epstein-Barr virus is composed of unique DNA interspersed with repetitive sequences. This organization suggests that Epstein-Barr virus provides a useful model for studying the function(s) of repetitive sequences in eukaryotic chromosomes. The primary structure of two of the repeat sequences, the 3072 bp large internal repeat, or BamHI-W repeat

36. The observed global warming record: What does it tell us?
Global, near-surface temperature data sets and their derivations are discussed, and differences between the Jones and Intergovernmental Panel on Climate Change data sets are explained. Global-mean temperature changes are then interpreted in terms of anthropogenic forcing influences and natural variability. The inclusion of aerosol forcing improves the f
