This graduate work approaches the study of Statistical Process Control - SPC, in a stage production of an industrial frame, aiming to use the tool of statistical process control (SPC) to assess the process capability. Where the process needs improvement as well not meet the specifications. Assessing the needs that the company needs to improve quality management, and the difficulties they present during the implementation of the CEP. The present study is to use the method of case study. The results are presented through study of the level of defects using Pareto diagrams and control chart by - (p) fraction defective, and checking the capacity and stability of the process using control charts and histograms XbarraR. The process demonstrated the need for improvements in process and quality management. At the end of the work are presented suggestions for improving the quality system of the company

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n =30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

The aim of this study was to evaluate the effects of the use of a high-power gallium-aluminum-arsenide diode laser (GaAlAs; 808 nm, 1 W, 20 s, 20 Hz, 10 J) alone or as adjunctive therapy to scaling and root planing in the treatment of induced periodontitis in rats. Periodontitis was induced by placing a ligature around the mandibular first molar of 60 rats. After 7 days, the ligature was removed and the animals were divided into four groups as follows: C (control), no periodontal treatment; SRP, scaling and root planing (SRP); DL, diode laser (DL) irradiation treatment; and SRP/DL, both SRP and DL irradiation treatment. Five animals from each group were euthanized at 7, 15, and 30 days posttreatment. The effectiveness of the treatments was evaluated in the furcation area using histopathological analysis, histometric analysis of alveolar bone loss (ABL), and immunohistochemical detection of tartrate-resistant acid phosphatase (TRAP), runt-related transcription factor 2 (RUNX2), and osteocalcin (OCN). DL, alone or in combination with adjunctive therapy to SRP in the treatment of experimental periodontitis, resulted in a decreased local inflammatory response. At 7-days posttreatment, the DL and SRP/DL groups had fewer TRAP-positive cells and more RUNX2-positive cells. There was greater OCN immunolabeling in the DL group than in the C and SRP groups at 15 days. There was less ABL in the DL and SRP/DL groups at 15 and 30 days. In conclusion, DL was effective in the treatment of ligature-induced periodontitis in rats, both when used alone and when used as adjunctive therapy to SRP.
