STUDY REGARDING QUALITY FOOD PRODUCTS ON THE ZLATNA MARKETPLACE (ALBA COUNTY)

The present work approaches a few problems related to the quality parameters of the food products starting from the present demands of the market economy. We have included in our study a large range of products that are permanently present market place, in a industrialized area. Some of them are vegetable products like: corn, potatoes, cabbage, carrot, spinach, together with other products. The study results highlight the degree of heavy metals contamination of these goods.vegetable products, heavy metals contaminations

Distributed Control Systems for a Wastewater Treatment Plant: Architectures and Advanced Control Solutions

This chapter is focused on the development and implementation of a distributed and hierarchized control system for the wastewater treatment plant (WTP) Calafat, Romania. The primary control loops for both treatment lines (water and activated sludge) are developed and analyzed. Also, the distributed control system (DCS) architecture of the wastewater treatment plant is presented, and the advantages of the proposed control structure are highlighted. In order to increase the performance of the overall control system, some advanced control solutions are investigated. More precisely, multivariable adaptive and robust control algorithms are proposed for the activated sludge bioprocess. Several realistic simulation experiments are performed, and the obtained results are analyzed

Intestinal Obstruction Secondary to Postoperative Peritoneal Adhesions: the Tolerability of the Conservative Treatment

Introduction: The present study aims to determine the mean duration of the conservative management that can be tolerated by the patients with intestinal obstruction secondary to the postoperative peritoneal adhesions, in order to postpone the surgical intervention. Material and method: The data of the patients with intestinal obstruction secondary to postoperative peritoneal adhesions were retrospectively collected and analysed. The number of readmissions, the type of the therapeutic management, the duration of the conservative treatment, the number of surgical reinterventions and the intraoperative aspect represented the studied variables. Results: 543 patients with intestinal obstruction secondary to postoperative peritoneal adhesions, admitted in the Surgical Department of “Sfântul Pantelimon” Emergency Hospital from Bucharest, Romania, between January 2014 and July 2018, were enrolled in the study. 233 patients underwent conservative treatment, 310 patients being surgically treated. The mean interval necessary for the monitoring of the patients non- operatively treated was 7 days, within a range of 2 to 14 days. For the surgically treated cases, the mean monitoring interval was 5 days, within a range of 1 to 14 days. Among the patients that underwent surgical treatment, there were 276 cases of adhesiolysis, 31 cases of intestinal resection with anastomosis and 3 cases of intestinal resection with terminal ileo- or colostomy. Conclusion: Under strict monitoring, a signifi cant number of cases of intestinal obstruction secondary to postoperative peritoneal adhesions can, successfully, be treated using conservative management, within 7-10 days

Postoperative Peritoneal Adhesion Syndrome - a Challenging Issue in Laparoscopic Surgery

Introduction: The presence of the peritoneal adhesions during surgery represents an element that can negatively influence the intra- and postoperative evolution of the patients. This article aims to evaluate the impact of the peritoneal adhesions on the postoperative recovery of the patients. Material and method: The data of 1407 patients undergoing laparoscopic cholecystectomy between January 2014 and October 2018 were retrospectively analyzed. Patients were organized into two groups: the case group, consisting of patients for whom peritoneal adhesions were identifi ed during the surgical intervention, and the control group, with patients that had no postoperative peritoneal adhesions. The degree of association between the presence of the peritoneal adhesions and the operative time, the risk of laparoscopic conversion to laparotomy and the risk of intra- or postoperative complications was analyzed. Results: For 537 patients (38.16%) included in the study postoperative peritoneal adhesions were identifi ed at the time of the laparoscopic cholecystectomy. A direct association was observed between the presence of postoperative peritoneal adhesions and the risk of conversion, a longer operative time or period of hospitalization and the risk of postoperative ileus. Conclusions: Postoperative peritoneal adhesions represent an independent risk factor for the increasing morbidity and mortality rates in patients undergoing laparoscopic cholecystectomy

USE OF IT TOOLS IN NONCONVENTIONAL TECHNOLOGY APPLICATIONS

For the first time, computers could be an important part of measuring systems more than 20 years ago thanks to serial communications like RS-232 and GPIB. By connecting measuring equipment directly to the computer, potential increases in productivity and reductions in error rates could be realised, processing that was unique to the manual transfer of data that was eventually fed into the computer for further analysis Some manufacturers are thinking of ways to use voltage deviation from average discharge as a signal to automatically adjust the feed rate to the amount of metal being processed or to retract the tool if a short circuit occurs, thus eliminating the need for human intervention. The knowledge-based organization stands to gain significantly by incorporating computerization for nonconventional technologies, making this a matter of strategic importance.  Knowledge management could greatly benefit from the automation of routine, time-consuming tasks made possible by combining IT and information systems.
