Plum (Prunus domestica) is a seasonal nutraceutical fruit rich in many functional food nutrients such as vitamin C, antioxidants, total phenolic content, and minerals. Recently, researchers have focused on improvised technologies for the retention of bioactive compounds during the processing of perishable fruits; plum is one of these fruits. This study looked at how the percentage of moisture content and percentage of acidity were affected by conventional drying and osmotic dehydration. Total phenolic content (mg GA/100 g of plum), total anthocyanin content (mg/100 g), and vitamin C (mg/100 g) Conventional drying of fruit was carried out at 80.0 ℃ for 5 h. At various temperatures (45.0 ℃, 50.0 ℃, and 55.0 ℃) and hypertonic solution concentrations (65.0 B, 70.0 B, and 75.0 B), the whole fruit was osmotically dehydrated. It was observed that the osmotically treated fruit retains more nutrients than conventionally dried fruit. The total phenolic content of fruit significantly increased with the increase in process temperature. However, vitamin C and total anthocyanin content of the fruit decreased significantly with process temperature, and hypertonic solution concentration was observed. Hence, it was concluded that osmodehydration could be employed for nutrient retention in plum fruit over conventional drying. This process needs to be further refined, improvised, and optimised for plum processing.
Metamaterial perfect absorber is very important in the study of refractive index sensor. The time domain finite difference method is used to simulate the surface plasmon structure. The double nanorod periodic structure is designed, and the parameters of the top layer structure are optimized according to the impedance matching principle, and the absorption rate of the structure to the light wave reaches 99.6% when the wavelength is about 12 mm. The absorption spectroscopy of the structure is studied with the change of the refractive index of the spatial medium around the structure, and the sensitivity of the double nanorod structure is 4,008 nm/RIU, which can be used to measure the refractive index of the gas.
This study explores the experiences and perceptions of Chinese postgraduate students in the UK regarding online learning, focusing on the Community of Inquiry (CoI) framework. Semi-structured interviews were used to collect qualitative data, which were analyzed thematically. The findings reveal positive perceptions of online learning, challenges related to technology and infrastructure, the significance of social interaction and collaboration, and the limited impact of teaching quality on student satisfaction. The study emphasizes the importance of the CoI framework in designing effective online learning environments. Limitations include a small sample size and potential bias. Future research should involve larger and more diverse samples, investigate different teaching strategies, and enhance student agency and self-regulated learning in online education. Overall, this study contributes to understanding the applicability of the CoI framework and its potential for improving online learning experiences.
Over the last two decades, governance for global health has garnered more attention from policymakers, decision-makers, and scholars from several disciplines. The health sector has also become more dynamic and complicated as a result of several factors that have influenced organizational development. The issue of sustainability is clearly raised with specific emphasis and urgency in the context of the global healthcare system. Some countries have been altering their healthcare systems to improve healthcare performance. University hospitals as the main providers of high-quality healthcare services in China, have an irreplaceable role in promoting the construction of healthy China. This study strategic triangle as an analytical framework to identify the key factors that influence university hospital in China and better comprehend how public value is conceptualized and implemented in practice. The study was conducted by qualitative method, five university hospitals designated as “Grade A tertiary hospitals” and semi-structed interviews were carried out with 33 participants, including experts, university hospital leadership level, and basic level. The study revealed that there are eight (8) major factors influencing the development of university hospitals in China. University hospital administrators must be prepared to assess and respond to factors that enhance or hinder implementation continuously and methodically. These insights can be used to improve early preparedness, but additional study in this area is required to better understand the driving factors, action models, and techniques for achieving sustainable development in university hospitals.
