Kinetic theory and thermalization of weakly interacting fermions

Weakly interacting quantum fluids allow for a natural kinetic theory description which takes into account the fermionic or bosonic nature of the interacting particles. In the simplest cases, one arrives at the Boltzmann-Nordheim equations for the reduced density matrix of the fluid. We discuss here two related topics: the kinetic theory of the fermionic Hubbard model, in which conservation of total spin results in an additional Vlasov type term in the Boltzmann equation, and the relation between kinetic theory and thermalization.Comment: 19 pages, submitted to proceedings of the conference "Macroscopic Limits of Quantum Systems", Munich, Germany, March 20-April 1, 2017 (eds.

Calcium Supplementation

Calcium supplementation is recommended for patients with osteopenia or osteoporosis to prevent further bone density loss. However, recent studies have shown associations between high calcium supplementation and increased cardiovascular disease and kidney stones. This study looks into current recommendations for calcium supplementations in light of these new findings.https://scholarworks.uvm.edu/fmclerk/1159/thumbnail.jp

On the use of non-canonical quantum statistics

We develop a method using a coarse graining of the energy fluctuations of an equilibrium quantum system which produces simple parameterizations for the behaviour of the system. As an application, we use these methods to gain more understanding on the standard Boltzmann-Gibbs statistics and on the recently developed Tsallis statistics. We conclude on a discussion of the role of entropy and the maximum entropy principle in thermodynamics.Comment: 29 pages, uses iopart.cls, major revisions of text for better readability, added a discussion about essentially microcanonical ensemble

Mesenteric Panniculitis Mimicking Acute Pancreatitis: A Case Report and Literature review

Mesenteric panniculitis is a rare disease characterized by an chronic non-specific inflammation of the adipose tissue of the mesentery of the small intestine and colon. The specific etiology of the disease is unknown. The condition is referred to as retractile mesenteritis when fibrosis predominates but generally sclerosing mesenteritis is the common pathological terminology used for the condition. CT scan is highly suggestive of the diagnosis which may be confirmed by surgical biopsies. Treatment is empiric and surgical resection is sometimes attempted for definitive therapy. We report a case of a 77 year old man presenting with CT features of mesenteric panniculitis currently in remission. The aim is to highlight this condition and possibly avoid the negative laparotomies done on suspected cases of pancreatitis in our region.Key words: Mesenteric Panniculitis, Mimicking, Acute Pancreatiti

Simulation of 3-D Conjugate Heat Transfer in a rectangular cooling channel

Over the course of the past decade, a number of investigations have been conducted to better understand the fluid flow and heat transfer in channel heat sinks. In this study full three-dimensional (3-D) conjugate heat transfer analysis is performed by computational fluid dynamics (CFD) codes for evaluating the thermal performance of rectangular cooling channel (heat sinks)
