Computational Analysis of a Colored Maillard Reaction Product from the Conceptual Density Functional Theory Viewpoint | Chapter 06 | Theory and Applications of Chemistry Vol. 1

This computational study assessed ten density functionals that include CAM-B3LYP, LC-ωPBE, M11,M11L, MN12L, MN12SX, N12, N12SX,ωB97X, andωB97XD related to the Def2TZVP basis set together with the SMD solvation model. These are assessed in calculating the molecular properties and structure of the pyrrolopyrrole-2-carbaldehyde molecule (PPA) in water. The calculated HOMO and LUMO of PPA are presented through graphical sketches overlapped to its chemical structure. The chemical reactivity descriptors for the systems are calculated via the Conceptual Density Functional Theory. The choice of active sites applicable to nucleophilic, electrophilic as well as radical attacks is made by linking them with Fukui functions indices, electrophilic and nucleophilic Parr functions, and the condensed dual descriptor ∆f(r).

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

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)

Scientific values of ECA Ligation | Chapter 06 | New Horizons in Medicine and Medical Research Vol. 8

  Previously, carotid artery ligation was done as an emergency procedure to stop severe haemorrhages in the head and neck. Despite this, it was abandoned because to high patient mortality and morbidity. However, ECA ligation, a more selective branch of the carotid artery, has been popular for the same goal in recent decades due to the lack of or modest postsurgical problems compared to Transarterial embolization (TAE). However, a good surge seal pack, especially in the maxilla, is occasionally required to regulate both collateral circulation and backflow of blood from the internal carotid arteries distal to the carotid arteries (ICA). ECA ligation, on the other hand, might be a superior alternative for controlling life-threatening uncontrolled bleeding in this area.
