Hybird, Solar and Biomass Energy System for Heating Greenhouse Sweet Coloured Pepper | Chapter 07 | Advances in Applied Science and Technology Vol. 1

The  main  drawback  of  greenhouse  heating systems  based on  solar  energy  is  the  unavailability  at nighttime and the variation of its value from hour to hour and month to another during daylight-time. However, use the combination of two-source of renewable energy (solar energy and biomass heat energy) successfully provides appropriate amount of heat energy for heating greenhouse at nighttime. The commercial greenhouses have the highest demand of heat energy for heating the indoor air as compared with other agricultural industry sectors. The investigation presented in this article is aimed at  evaluating  the  technical  and  design  feasibility  of  using  biomass  heat  energy  to  assist  the  solar energy  heating  system  at  the  eastern  area  of  coastal  delta,  Egypt  (Latitude and  longitude  are 31.045°N  and  31.37°E,  respectively,  and  altitude  6.0  m  above  the  sea  level).  The  hybrid  heating system (solar and biomass heating systems) is mainly consists of two different heating systems, a complete solar heating system (6 collectors, storage tank and heat exchanger) and biomass burner (water and air coils, and air heat exchanger). The obtained results reveal that, over 180 days heating season (from November 2015 to March 2016) the solar heating system collected 12712 kWh (45.763 GJ) of which 12316 kWh (44.338 GJ) of solar heat energy was stored in the storage tank. It provided 30.32% of the total heat energy required for heating the greenhouse. The biomass heating system provided  19795  kWh  (71.262  GJ)  of  heat  energy  which provided  58.55%  of  the  total  heat  energy required  for  heating  the  greenhouse  (225.389  kWh).  Ultimately,  the  heat  energy  provided  by  the hybrid  heating  system  (88.87%)  has  been  used  successfully  to  heat  up  the  indoor  air  of  the commercial  greenhouse  sweet  coloured  pepper.  It  also  provided  high  water  use  efficiency  of 29.860 kg/m3. High water use efficiency (29.860 kg/m3) and high annual irrigation water productivity (447.9 LE/m3) were achieved during this study.

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
