Revista do Colégio Brasileiro de Cirurgi?es , 2013,
Abstract: Spontaneous esophageal rupture carries high morbidity and mortality. The main prognostic factor is early diagnosis, before 12 hours, and appropriate treatment. This is a case report of a 41-years-old man with late esophageal rupture diagnosis treated successfully with transmediatinal esophagectomy and esophageal-gastric tube cervical anastomosis.

Abstract: background:choledocholithiasis treatment is still a controversial topic, being done either with endoscopic retrograde cholangiopancreatography before laparoscopic cholecystectomy or by the use of laparoscopic cholecystectomy and exploration of common bile duct. according to literature, there is an unsuccessful rate of 6% when utilizing pre-operative endoscopic retrograde cholangiopancreatography. aim: to report a case of a patient who underwent intraoperative cpre as a solution to choledocholithiasis treated unsuccessfully by cpre. case report:- we present a case report of a 45-year-old patient, female, who was admitted to an emergency room with abdominal pain in the epigastrius and right hypochondrium. ultrasonography showed choledocholithiasis, and the patient was indicated to a pre-operative endoscopic retrograde cholangiopancreatography, by which the catheterization of papilla was unsuccessful. the patient was then, submitted to a laparoscopic cholecystectomy and exploration of the common bile ducts by preoperative and intraoperative endoscopic retrograde cholangiopancreatography with the catheterization of papilla being guided by a guiding thread which was introduced through the cystic duct. a duodenoscopy with the capture of the guiding thread was performed, allowing the passage of papillotome, giving sequence to the preoperative endoscopic retrograde cholangiopancreatography, by which gallstones were removed. the patient had a satisfying recovery being discharged on the second post-operative day. conclusion: in this case, the choledocholithiasis management by intraoperative endoscopic retrograde cholangiopancreatography with laparoscopic cholecystectomy was considered both safe and effective.
HTS Theological Studies/Teologiese Studies , 2012,
Abstract: The article aims to investigate the Calvin’s Genevan Service Order. It focuses on the question how the Psalter Calvin shaped the worship of the Reformed Church in Geneva. The article follows the critical edition of the Genevan prayer in Calvini Opera Selecta and in the German Studienausgabe as the two main published editions of the Genevan order with its related texts. The article shows that Calvin adhered to the general line of the Swiss and Upper German Reformations. It explores the understanding of worship reflected in the Genevan Service Order and the specific significance of its musical aspect. The article illustrates why Calvin gave the psalms the place he did in Genevan Reformed worship.
“If Luther will accept us with our confession …”: The Eucharistic controversy in Calvin’s correspondence up to 1546
Alasdair Heron
HTS Theological Studies/Teologiese Studies , 2009, DOI: 10.4102/hts.v62i3.390
Abstract: The article explores Calvin's attitude to the Eucharistic controversy between Wittenberg and Zurich in the years up till Luther's death in 1546. The main source is Calvin’s letters from that period, which cast a differentiated light on his aims, hopes and disappointments on the question as well as on his relations to other leading Reformers. Account is also taken of several recent publications, which suggest revision of some long-standing views in Calvin scholarship.
Asymmetrically Doped Polyacetylene
Heron Caldas
Physics , 2008, DOI: 10.1016/j.nuclphysb.2008.09.002
Abstract: Doped one-dimensional (1D) conjugated polymers, such as polyacetylene, have a conductivity of some metals, like copper. We show that when this polymer is asymmetrically doped, unexpected properties are revealed, when compared to the behavior of the symmetrically standard doped systems (SDS). Depending on the level of imbalance between the chemical potentials of the two involved fermionic species, the polymer can be converted into a 1D partially or fully spin polarized organic conductor.
Cold asymmetrical fermion superfluids
Heron Caldas
Physics , 2003, DOI: 10.1103/PhysRevA.69.063602
Abstract: In this work we investigate the general properties and the ground state of an asymmetrical dilute gas of cold fermionic atoms, formed by two particle species having different densities. We have show in a recent paper, that a mixed phase composed of normal and superfluid components is the energetically favored ground state of such a cold fermionic system. Here we extend the analysis and verify that in fact, the mixed phase is the preferred ground state of an asymmetrical superfluid in various situatiations. We predict that the mixed phase can serve as a way of detecting superfluidity and estimating the magnitude of the gap parameter in asymmetrical fermionic systems.
On the Chemical Potentials in Cold Heterogeneous Mixed Phases
Heron Caldas
Physics , 2004,
Abstract: We study the relations among the chemical potentials of paired and unpaired particles in a cold asymmetrical fermionic mixed phase in thermodynamical equilibrium. We show how the chemical potentials are expressed in terms of the parameters of the mixed phase energy. We propose a way of estimating the value of the BCS gap in optical atomic traps experiments.
Phase Transition in Imbalanced Fermion Superfluids
Heron Caldas
Physics , 2006,
Abstract: In this chapter the recent theoretical work on phase transition in imbalanced fermion superfluids is reviewed. The imbalanced systems are those in which the two fermionic species candidate to form pairing have different Fermi surfaces or densities. We consider systems subjected to weak interactions. In this scenario two distinct phase transitions are predicted to occur. A thermodynamical phase transition, induced by the temperature (T), and a quantum phase transition as a function of the increasing chemical potentials asymmetry, that takes place at zero temperature. We also briefly discuss some recent experimental work at non-zero T with imbalanced Fermi gases in cold atomic traps.
Temperature effects on the magnetization of quasi-one-dimensional Peierls distorted materials
Heron Caldas
Statistics , 2010, DOI: 10.1088/1742-5468/2010/03/P03027
Abstract: It is shown that temperature acts to disrupt the magnetization of Peierls distorted quasi-one-dimensional materials (Q1DM). The mean-field finite temperature phase diagram for the field theory model employed is obtained by considering both homogeneous and inhomogeneous condensates. The tricritical points of the second order transition lines of the gap parameter and magnetization are explicitly calculated. It is also shown that in the absence of an external static magnetic field the magnetization is always zero, at any temperature. As expected, temperature does not induce any magnetization effect on Peierls distorted Q1DM.
An Effective Field Theory Model for One-Dimensional ${\rm CH}$ Chains: Effects at Finite Chemical Potential, Temperature and External Zeeman Magnetic Field
Heron Caldas
Statistics , 2011, DOI: 10.1088/1742-5468/2011/10/P10005
Abstract: In this work we use an effective field theory model to investigate doped $\rm (CH)_x$ chains under the influence of an external constant Zeeman magnetic field $B_0$, at zero and finite temperature, in the mean-field approximation and beyond. We consider both homogeneous and inhomogeneous $\Delta(x)$ condensates and briefly discuss the possibility of using these materials as partially polarized 1D organic conductors.
