Production of Seedlings of Fast - Growth Tree of Paulownia elongata S. Y. Hu | Chapter 16 | New Perspectives in Agriculture and Crop Science Vol. 1

The major method of propagation of varieties and hybrids of Paulownia elongata is vegetative (asexual) method. Paulownia elongata can be propagated by macropropagation techniques (root cuttings, green cuttings and by micropropagation technique, tissue culture or in vitro. Today the tissue culture method is the most modern biotechnological method. In Bosnia and Herzegovina and regions of former Yugoslawia, more and more Paulownia elongata seedlings are being produced and new plantations of Paulownia elongata areestablished. This paper deals with the methods of propagation and problems in raising Paulownia elongata planting materials. The work aims to produce seedlings of fast-growth Paulownia elongata, Shan Tong hybrid and the possibility of propagation through different methods. Propagation by green cuttings, root cuttings and in vitro propagation was tested. After 15 days, the percentage of rooting for the green cuttings was 100%, and there were no dead plants, the average number of roots was 13.86 pcs per plant and roots were of different lengths. The length of the cuttings had an impact on the growth of plants because the smallest cuttings was of 1.5 cm (4 pcs from 30 plants or 1.33%), whereas cuttings of 5 cm (26 out of 30 plants or 86.6%), showed the best rooting. For in vitro propagation, meristems of mother plants were used for establishing of tissue culture. The plants showed a survival rate of 80-90% . Production of Paulownia elongata seedlings by different methods of vegetative propagation provides a variety of options to producers, depending on what kind of equipment they have. In vitro production is the most expensive but also the fastest method because a large number of seedlings can be produced in a short time. It is recommended that in vitro propagation should be used to build mother plant stock and that in the coming 2-3 years the green cuttings from super-elite planting material are going to be used.

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)

A Case Report on Delayed Diagnosis of Glioblastoma | Chapter 07 | New Horizons in Medicine and Medical Research Vol. 8

  The clinical and radiological indications of a concomitant tumour may be hidden by the rupture of a cerebral aneurysm. The goal of this study is to raise awareness about the dangers of delayed diagnosis by recounting the case of a patient who had a subarachnoid haemorrhage that hid the presence of a glioblastoma for several months. Only a few similar cases have been recorded in the literature: The therapy of two recent severe neurosurgical illnesses is discussed in this article.
