1. Cadaveric study of anatomical measurement of isthmus parameters of lumbar spine to guide cortical bone screw placement
SUMMARY OBJECTIVE: To reduce surgical exposure and improve accuracy, this study evaluated the anatomical distance parameter D (including D1, D2, and D3) of the lumbar isthmus for cortical bone screw insertion. METHODS: A total of 25 structurally complete lumbar dry specimens were used for lumbar anatomy measurements. The six cadaver specimens were divided

2. A 2.4 GHz Coplanar Solar Cell Patch Antenna with a Semi-Analytical Evaluation of Temperature Effects
Abstract Solar cells integrated with antennas have aroused scientific interest as an attractive energy source alternative in low power devices for IoT and Wireless Sensor Network applications. Since the space for all components in the systems is scarce, different integration ideas have been proposed in this field. However, further analysis of the performance

3. PhotoMetrix UVC: A New Smartphone-Based Device for Digital Image Colorimetric Analysis Using PLS Regression
A novel free PhotoMetrix UVC is proposed for both the operation of a universal serial bus video camera (UVC) and multivariate image analysis, allowing a full solution for point-of-use analysis. A UVC was placed in an open-source 3D-printed chamber illuminated by a white light-emitting diode (LED) with controlled intensity of light. The digital images capture

4. Abdominal drain amylase on the first day after pancreatectomy: a predictive factor for pancreatic fistula
SUMMARY OBJECTIVE: To analyze abdominal drain on the first postoperative day and evaluate its predictive nature for the diagnosis of Pancreatic Fistula exclusion, seeking to establish a cutoff point from which lower values demonstrate safety in excluding the possibility of this complication. METHODS: From August 2017 to June 2020, data from 48 patients und

5. Flexible ureterorenoscopy and laser lithotripsy with regional anesthesia vs general anesthesia: A prospective randomized study
ABSTRACT Purpose To compare the effect of general anesthesia (GA) and regional anesthesia (RA) on f-URS outcomes and surgeon comfort. Material and Methods The study was conducted between June 2017 to January 2018 and data collection was applied in a prospective, randomized fashion. 120 patients participated in the study and were divided into RA group (n=

6. Anesthesia upstream of the alcoholic lesion point alleviates the pain of alcohol neurolysis for intercostal neuralgia: a prospective randomized clinical trial
OBJECTIVES: Alcohol for intercostal neuralgia may induce severe injection pain. Although nerve block provided partial pain relief, alcohol might be diluted, and the curative effect decreased when the local anesthetic and alcohol were given at the same point. Therefore, we observed the modified method for intercostal neuralgia, a Two-point method, in which t

9. INTEGRATING REAL TIME OPTIMIZATION AND MODEL PREDICTIVE CONTROL OF A CRUDE DISTILLATION UNIT
Abstract This work reports the integration of Real Time Optimization and Model Predictive Control in the multi-layer control structure of an existing Crude Distillation Unit (CDU) of an oil refinery. The MPC considers output control zones and targets for the inputs or outputs. Both the infinite horizon and the finite output horizon controllers were tested. T

11. ESQUARAÍNAS CIS E TRANS SUBSTITUÍDAS: APLICAÇÃO EXPERIMENTAL DA TEORIA DE GRUPO EM ESPECTROSCOPIA VIBRACIONAL
This work shows a practical application of the group theory to a relatively simple molecular system, as well its impact in the results obtained through vibrational spectroscopic techniques. Squaraines substituted by dicyanemethylene groups have been extensively studied, and after minor approaches in the sense to facilitate the point group determination, they
