Biodesulfurization of Sour Crude Oil: An Advanced Study | Chapter 11 | Current Strategies in Biotechnology and Bioresource Technology Vol. 1

Crude oil is one of the most important types of fossil fuel in the world. It is an economically important commodity that is massively used in different fields of industrial activities. The poor quality of crude oil is related to high sulfur content, which translates to lower profit margins and negatively impacts air quality standards. Polyaromatic sulfur heterocycles (PASHs) that exist in crude oil require an efficient reduction method to achieve a significant desulfurization level. Recently, biodesulfurization (BDS) is gaining greater attention attributed to its environmentally benign bioprocess; the possible benefits of BDS include lower capital and processing costs. Studies have reported that BDS is urgently needed for the desulfurization of recalcitrant organic sulfur than relative to a traditional approach, hydrodesulfurization (HDS). The establishment of commercial-scale bio-refining technology relies upon achieving major advancement in BDS, which concerning less expensive and sufficient production of highly active and stable biocatalysts. These bacteria can be adapted to intense conditions encountered in petroleum refineries. In this paper, a review on BDS processes for removing recalcitrant thoiphenic components from sour crude oil is conducted, covering the aim of most studies concerning desulfurizing bacteria, which enables deep desulfurization of organosulfur compounds by 4S pathway, maintaining the caloric value of the fuel.

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
