Influence of Sulfurization Time on SbS Synthesis Using a New Graphite Box Design.

In recent years, antimony sulfide (SbS) has been investigated as a photovoltaic absorber material due to its suitable absorber coefficient, direct band gap, extinction coefficient, earth-abundant, and environmentally friendly constituents. Therefore, this work proposes SbS film preparation by an effective two-step process using a new graphite box design and sulfur distribution, which has a high repeatability level and can be scalable. First, an Sb thin film was deposited using the RF-Sputtering technique, and after that, the samples were annealed with elemental sulfur into a graphite box, varying the sulfurization time from 20 to 50 min.

[Precision of ELISA-IgE and ELISA-IgG determination in the postoperative follow-up of patients with hepatic echinococcosis].

Introduction: Follow-up of patients undergoing surgery for hepatic echinococcosis (HE) is essential to ensure the absence of infection. The aim of this study was to determine the behavior over time of specific IgG and IgE to Echinococcus granulosus determined by the ELISA technique (ELISA-IgG and ELISA-IgE) in patients undergoing surgery for HE.

Material And Method: We performed a concurrent cohort study of patients who underwent surgery for HE between 1994 and 2003 in the Regional Hospital of Temuco, Chile.

[Study of collagen and elastic fibers of connective tissue in patients with and without primary inguinal hernia].

Background: There are few studies looking for collagen matrix defects in patients with inguinal bernia.

Aim: To study the skin connective tissue in patients with and without inguinal bernia.

Patients And Methods: Skin from the surgical wound was obtained from 23 patients with and 23 patients without inguinal bernia.
