Preliminary Evaluation of Growth and Phenological Features of Exotic Apple Varieties under High Density Plantation System | Chapter 03 | Advances in Applied Science and Technology Vol. 5

The  apple (Malus domestica Borkh.) is believed to  have  originated  in  the  Caucasus  mountains  of south-western Asia.  The cultivated apples belong to the species Malus pumila or Malus sylvestris. Apple is undoubtedly the most important temperate fruit. It is the most important temperate fruit in the world and India stands 5th in the production of apple. In India, apple cultivation is extremely profitable and has become  the  major  industry  of  Jammu and  Kashmir and Himachal  Pradesh. The present commercial cultivars of apple are far improved from the wild apples from which they developed over many centuries. And to commercialize improved varieties of apple in India, the varieties need to be evaluated for their growth characteristics. Keeping this view, the study was taken to evaluate four new exotic  varieties  of  apple  viz., Super Chief  Sandidge, Gala  Red  Lum, Fuji Zhen Aztec  and Golden Clone B grafted on rootstock M9T337 for their various growth and phenological characteristics. The study  showed  statistically  significant  differences  among varieties  in  their various  characters.  Tree morphological characteristics revealed variety Super Chief Sandidge to be the most dwarf variety with least tree height (1.31m) and incremental growth in tree height (23.64cm) while the variety Fuji Zhen Aztec reported to be most vigorous with an average tree height of (1.96m), and highest increase in tree height in a  season  (31.04 cm).  Various phenological stages were observed earliest in variety Gala Red Lum and last in Golden Clone B. All the varieties appeared to be promising under Kashmir condition and can be recommended for further research, mass multiplication and ultimate adoption by orchardists of valley. On the basis of their vegetative behavior, Super Chief Sandidge appeared to be highly dwarf variety in terms of tree morphology and other as moderate. It was concluded that the different  exotic  cultivars  studied  had  different  flowering  phenological  features  which  will  permit  to establish  proper  varietal  combinations  for  pollination  to  improve  profitability  of  high  density  apple orchards. Further, it can be suggested that in variety Super Chief Sandidge further close plantings at the rate of 3906 trees/ha can be recommended to utilize the inter tree space more efficiently and the productivity further high.

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

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili
