Productivity of Fissured Aquifers from Precambrian Basement of San Pedro (Southwestern of Côte d’Ivoire) | Chapter 01 | Current Perspectives to Environment and Climate Change Vol. 2

This study focuses on characterization of hard-rock aquifers in South Western Côte d’Ivoire where previous quantitative hydrogeological studies were not enough. San Pedro is localized in South-Western Côte d'Ivoire where the basement is dominated by folded and fissured crystalline rocks. Several years ago, many drinking water supply initiatives were performed in this study area considering its particular geographical location and hydrological trumps. This study aims to contribute to the best knowledge of hydrogeological potentialities of this basement pointing to reduce doubtful quality surface water using. The database incorporated satellite radar image and reports of boreholes. The methodological approach was based on remote sensing, fracture characterizing, pumping tests reports and multivariate statistical analysis. Treatment of satellite image highlighted 271 fractures ranged between 2.11 and 39.37 km. Rock mass permeability due to fractures fluctuated between 2.35E-07 and 8.13E-06 m.s-1. Spatial distribution of aquifers permeability due to fractures has highlighted three theoretical groundwater flow paths. Water yields delivered from aquifers of gneiss, granodiorite and migmatite are higher than those delivered from the aquifer of mica schist and granite. The productivity of hard-rock aquifers did not exclusively depend on fracturing density and thicknesses of weathered layers. It is also influenced by the positioning of boreholes on fractures nodes, aquifer’s transmissivity, slope and the structure of bedrocks. Predictive relationship about disponibility of groundwaters was established by following equation: yield (Q) = 0,739Transmissivity + 0,138slope. Presents results have provided a guideline in searching potential zones of high quantity and best quality drinking water. These results are encouraging because they contribute to creating a Spatial Hydrogeological Information System for groundwater exploitation and management in South Western Côte d’Ivoire.

A Prospective Study about Safety and Efficacy of Perioperative Lidocaine Infusion | Chapter 09 | New Horizons in Medicine and Medical Research Vol. 8

 Opioids cause clinically significant side effects such as respiratory depression, immunosuppression, muscle rigidity, negative inotropism, nausea, vomiting, hyperalgesia, urine retention, postoperative ileus, and drowsiness. Perioperative opioids are a major contributor to the United States' and other countries' opioid epidemics. Non-opioid analgesics, particularly lidocaine, are becoming more common for perioperative use as a result of this. A total of 185 adult patients were randomly assigned to one of two groups: control group I (105 patients) [fentanyl group] or group ii (80 patients) [opioid-free anaesthesia group]. Lidocaine 1.5 mg/kg bolus followed by 1.5 mg/kg/h infusion intraoperatively, and 1.5-2 mg/kg/h infusion for 2-8 hours postoperatively were given to patients in both groups at anaesthetic induction. Intraoperatively, both groups received analgesic adjuvants such as diclofenac 75 mg, paracetamol 1 gm, and mgso4 30-50 mg/kg. If the mean arterial pressure (map)

A Brief Study of Middleware Technologies: Programming Applications and Management Systems | Chapter 15 | Novel Research Aspects in Mathematical and Computer Science Vol. 1

  Many platforms, services, applications, hardware, and operating systems are connected through the middleware layer. Because the middleware layer abstracts much low-level complexity and makes applications and software systems portable, it allows disparate systems to interface and function together in harmony. Middleware technologies enable software engineers to swiftly construct software systems and applications, allowing developers to focus on more important tasks. This chapter examines several types of middleware systems and discusses middleware capabilities, middleware operation, middleware's function in cloud-based systems, and the best middleware platforms to use. Middleware systems are widely utilised and can be found in practically any software system or application. Middleware programmes provide as a link between many sorts of systems and protocols. They serve as a mechanism for various systems. To successfully exchange information, it runs on a variety of operating system

Patients’ Perspective of Acute Post-operative Pain Management: A Multicentre Survey of Tertiary Hospitals in Maharashtra, India | Chapter 08 | New Horizons in Medicine and Medical Research Vol. 8

 When postoperative pain is adequately controlled, patients' satisfaction and patient-related outcomes (PROs) increase. Understanding the patients' perspective is crucial since it supports in the formulation of improvement strategies. Because wrong attitudes and assumptions might block pain alleviation, patients' attitudes and beliefs are critical. As a result, a multicenter study of patients' attitudes, beliefs, experiences, and satisfaction levels with acute postoperative pain management was done in Maharashtra's tertiary hospitals. In addition, the responses were examined to evaluate if the Acute Pain Service (APS) resulted in improved patient outcomes and satisfaction. A 13-item questionnaire adapted from previous studies was used to capture patients' experiences with postoperative pain treatment. The responses of 179 patients are included in the study. The findings revealed that 91.6 percent of patients experienced postoperative pain, with 75.5 percent
