An investigation of the 2D attractive Hubbard model

We present an investigation of the 2D attractive Hubbard model, considered as an effective model relevant to superconductivity in strongly interacting electron systems. We use both hybrid Monte-Carlo simulatio...

Deconfinement phase transition in QCD with heavy quarks

Using the pseudo-fermion method to simulate QCD with dynamical quarks we investigate the effects of heavy dynamical quarks of 2 flavours on the deconfinement phase transition in the quenched QCD. As the mass o...

Nuclear effects at large transverse momentum in a QCD parton model

Production of single mesons and opposite side pairs of mesons in hadron-nucleus and nucleusnucleus collisions are calculated in the framework of the QCD parton model, with the assumption that quarks and gluons...

Hormone content of mouse pancreatic islets subjected to different in vivo and in vitro functional demands

Mice treated for 4 days with tolbutamide displayed decreased serum glucose values with a concomitant decrease of their islet insulin content. Mouse islets cultured for 1 week at a low (3 mM) or a high (28 mM) ...

HPLC separation of natural oil triglycerides into fractions with the same carbon number and numbers of double bonds

A high performance liquid Chromatographie method was developed and tested on palm oil, low-erucic-acid rapeseed oil and cocoa butter. A 100-cm long column was used, packed with Nucleosil 5 C18 and using aceton...

Polarized Photoproduction of Large p_T Hadrons

Polarized photoproduction of large p_T hadrons is shown to yield new tests of QCD and a direct observation of the polarized gluon distribution function in the proton.

Correlation with large transverse momentum photons and the gluon structure function

The inclusive two-particle cross section for the production of largep _T photons and opposite side charged hadrons in proton-proton collisions is examined in detail in the frame...

Symmetric hadron pairs at large transverse momenta as a test of hard scattering models

The inclusive cross section of hadron pairs produced back-to-back with large transverse momenta is examined in the parton model. It is shown quantitatively that this cross section is determined directly by the...

Somatostatin content and release of isolated pancreatic islets from obese-hyperglycemic mice

The somatostatin content in pancreatic islets of obese-hyperglycemic mice was much lower than in the islets of normal mice. Also the release of somatostatin was decreased from the islets obtained from the obes...

Isolation and Preservation in Vitro of Human Pancreatic Islets Intended for Transplantation

Transplantation of pancreatic B-cells to diabetic patients would be an ideal way of restoring glycemie control and probably protecting against the development of vascular complications. While this goal has bee...

Effects of Insulin on the Glucagon Release, Glucose Utilization and ATP Content of the Pancreatic A Cells of the Guinea Pig

Previous studies have shown that insulin suppresses hyperglucagonemia in animals with experimental diabetes. This observation has raised the question whether the pancreatic A cell itself is insulin sensitive. ...

Induction of alloxan diabetes in obese-hyperglycemic mice (genotype obob)

Nachweis, dass fettsüchtige, hyperglykämische Mäuse nach Alloxan-Injektion einen erhöhten Blutzuckerspiegel und herabgesetzte Insulinkonzentrationen im Vergleich mit den unbehandelten Kontrolltieren zeigen. B-...

The proton leading-particle spectrum at accelerator energies

The proton spectrum in p-p inclusive reactions is described as being made up of two components: one of a quasi-diffractive type, and one analogous to the spectrum of a produced particle. With an exponential fo...
