Ornamental Aquatic Plant Nutrition: A Study on Qualitative and Quantitative Differences in Morphological Traits of Waterwort, Elatine gratiloides a Cunn | Chapter 06 | Emerging Issues in Science and Technology Vol. 3


Aim: To evaluate the efficacy of different organic substrates on quantitative and qualitative morphological traits of freshwater ornamental aquatic plant, waterwort (Elatine gratiloides).
Place and Duration of Study: Ornamental Fish and Aquatic Plant Unit, Department of Aquaculture, College of Fisheries, Guru Angad Dev Veterinary and Animal Sciences University Ludhiana (Punjab), India, from 11th April 2016 to 10th September 2016.

Methodology: An experiment was designed as per the principles of completely randomized block design with five treatments viz., control (T0) - without any manure, only soil/sand mixture (2:1), while vermi compost (T1), poultry manure (T2), cattle manure (T3) and goat manure (T4) @ 2% in triplicate in the mud pots of 3.5 L capacities.

Results: From the performance of waterwort with respect to different organic manures, it was observed that, there was considerable increase in plant biomass, total plant length, number of leaf and runners containing high nitrogen content. Among all treatments, poultry manure (T2) illustrated superior results and showed significant difference among the treatments, except for the cattle manure (T3).

Conclusion: Due to the easy availability of cattle manure in local market at affordable price compared with poultry manure; it is recommended that application of cattle manure @ 2% with soil/sand mixture (2:1) helps to increase plant biomass along with other parameters including plant length, number of leaves, number of runners with high nutrient value in terms of nitrogen content for culture and propagation of ornamental aquatic plant waterwort.

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
