Advancements in non-starch polysaccharides research for frozen foods and microencapsulation of probiotics

Martin LO,

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 4,   Pages 413-426 doi: 10.1007/s11705-009-0254-x

Abstract: Conventionally used in the food industry as stabilizing, thickening, gelling, and suspending or dispersing agents, non-starch polysaccharides such as xanthan gum are known to improve the texture of certain frozen products. Another polysaccharide that has received significant attention in recent years is chitosan, a natural biopolymer derived from chitin. In the wake of growing interest in finding ideal encapsulating agents for probiotics, non-starch polysaccharides have been investigated. Scattered research can be found on the effect of each individual polysaccharide, but there remains a void in the literature in terms of closely comparing the characteristics of non-starch polysaccharides for these applications, especially when more than one biopolymer is employed. A good understanding of the tools capable of elucidating the underlying mechanisms involved is essential in ushering further development of their applications. Therefore, it is this review’s intention to focus on the selection criteria of non-starch polysaccharides based on their rheological properties, resistance to harsh conditions, and ability to improve sensory quality. A variety of critical tools is also carefully examined with respect to the attainable information crucial to frozen food and microencapsulation applications.

Decomposition of perfluorooctanoic acid by microwave-activated persulfate: Effects of temperature, pH, and chloride ions

Yuchi LEE, Shanglien LO, Jeff KUO, Chinghong HSIEH

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 1,   Pages 17-25 doi: 10.1007/s11783-011-0371-x

Abstract: Microwave-hydrothermal treatment of persistent and bioaccumulative perfluorooctanoic acid (PFOA) in water with persulfate ( ) has been found effective. However, applications of this process to effectively remediate PFOA pollution require a better understanding on free-radical scavenging reactions that also take place. The objectives of this study were to investigate the effects of pH (pH= 2.5, 6.6, 8.8, and 10.5), chloride concentrations (0.01–0.15 mol·L ), and temperature (60°C, 90°C, and 130°C) on persulfate oxidation of PFOA under microwave irradiation. Maximum PFOA degradation occurred at pH 2.5, while little or no degradation at pH 10.5. Lowering system pH resulted in an increase in PFOA degradation rate. Both high pH and chloride concentrations would result in more scavenging of sulfate free radicals and slow down PFOA degradation. When chloride concentrations were less than 0.04 mol·L at 90°C and 0.06 mol·L at 60°C, presence of chloride ions had insignificant impacts on PFOA degradation. However, beyond these concentration levels, PFOA degradation rates reduced significantly with an increase in chloride concentrations, especially under the higher temperature.

Quantifying and mapping spatial variability of Shanghai household carbon footprints

Shangguang YANG,Chunlan WANG,Kevin LO,Mark WANG,Lin LIU

Frontiers in Energy 2015, Volume 9, Issue 1,   Pages 115-124 doi: 10.1007/s11708-015-0348-8

Abstract: Understanding the spatial variability of household carbon emissions is necessary for formulating sustainable and low-carbon energy policy. However, data on household carbon emissions is limited in China, the world’s largest greenhouse gases emitter. This study quantifies and maps household carbon emissions in Shanghai using a city-wide household survey. The findings reveal substantial spatial variability in household carbon emissions, especially in transport-related emissions. Low emission clusters are founded in Hongkou, Xuhui, Luwan, Jinshan, and Fengxian. High emission clusters are located in Jiading and Pudong. Overall, the spatial pattern of household carbon emissions in Shanghai is donut-shaped: lowest in the urban core, increasing in the surrounding suburban areas, and declining again in the urban fringe and rural regions. The household emissions are correlated with a number of housing and socioeconomic factors, including car ownership, type of dwelling, size of dwelling, age of dwelling, and income. The findings underscore the importance of a localized approach to low-carbon policy-making and implementation.

Ambient air pollution and lung disease in China: health effects, study design approaches and future research

Mandel,Christine Wendt,Charles Lo,Guangbiao Zhou,Marshall Hertz,Gurumurthy Ramachandran

Frontiers of Medicine 2015, Volume 9, Issue 3,   Pages 392-400 doi: 10.1007/s11684-015-0397-8

Abstract:

Ambient air pollution in China has worsened following dramatic increases in industrialization, automobile use and energy consumption. Particularly bothersome is the increase in the PM2.5 fraction of pollutants. This fraction has been associated with increasing rates of cardio-respiratory disease in China and elsewhere. Ambient pollutant levels have been described in many of China’s cities and are comparable to previous levels in southern California. Lung cancer mortality in China has increased since the 1970s and has been higher in men and in urban areas, the exact explanation for which has not been determined. The estimation of individual risk for Chinese citizens living in areas of air pollution will require further research. Occupational cohort and case-control designs each have unique attributes that could make them helpful to use in this setting. Other important future research considerations include detailed exposure assessment and the possible use of biomarkers as a means to better understand and manage the threat posed by air pollution in China.

Smart Society and Artificial Intelligence: Big Data Scheduling and the Global Standard Method Applied to Smart Maintenance Article

Ruben Foresti, Stefano Rossi, Matteo Magnani, Corrado Guarino Lo Bianco, Nicola Delmonte

Engineering 2020, Volume 6, Issue 7,   Pages 835-846 doi: 10.1016/j.eng.2019.11.014

Abstract:

The implementation of artificial intelligence (AI) in a smart society, in which the analysis of human habits is mandatory, requires automated data scheduling and analysis using smart applications, a smart infrastructure, smart systems, and a smart network. In this context, which is characterized by a large gap between training and operative processes, a dedicated method is required to manage and extract the massive amount of data and the related information mining. The method presented in this work aims to reduce this gap with near-zero-failure advanced diagnostics (AD) for smart management, which is exploitable in any context of Society 5.0, thus reducing the risk factors at all management levels and ensuring quality and sustainability. We have also developed innovative applications for a humancentered management system to support scheduling in the maintenance of operative processes, for reducing training costs, for improving production yield, and for creating a human–machine cyberspace for smart infrastructure design. The results obtained in 12 international companies demonstrate a possible global standardization of operative processes, leading to the design of a near-zero-failure intelligent system that is able to learn and upgrade itself. Our new method provides guidance for selecting the new generation of intelligent manufacturing and smart systems in order to optimize human–machine interactions, with the related smart maintenance and education.

Role of Intrahepatic Regional Immunity in Post-Transplant Cancer Recurrence Review

Jiang Liu,Chung Mau Lo,Kwan Man

Engineering 2022, Volume 10, Issue 3,   Pages 57-64 doi: 10.1016/j.eng.2021.11.012

Abstract:

Hepatic malignancy is a major indication for liver transplantation; however, post-transplant cancer recurrence is an emerging clinical challenge affecting long-term outcomes. Pre-transplant tumor biology, staging, and post-transplant immunosuppression regimens have been elucidated as risk factors for recurrent liver cancer. However, increasing evidence indicates that hepatic ischemia and reperfusion (IR) injury to allografts are crucial to providing a favorable immunologic microenvironment for cancer cell invasiveness and metastasis after liver transplantation. The association of severe graft injury in marginal grafts, such as small-for-size or fatty grafts, with lower recurrence-free survival rates in living donor liver transplantations, substantiates the correlation between hepatic IR injury and cancer recurrence. IR have been demonstrated to trigger intrahepatic immunological microenvironment remodeling, including pro-inflammatory responses exacerbating graft injury and anti-inflammatory responses promoting tissue repair. However, the role of regional immunity in post-transplant cancer recurrence is not comprehensively understood. This review describes the up-to-date evidence of the intrahepatic humoral microenvironment and regional regulatory immunological microenvironment induced by IR injury, as well as their roles in cancer recurrence after liver transplantation. A comprehensive understanding of regional immunity will provide novel precise diagnostic, therapeutic, and prognostic strategies for post-transplant cancer recurrence.

Fatigue Strength Evaluation of Resin-Injected Bolted Connections Using Statistical Analysis

aacute;sio, Grzegorz Stanisław Lesiuk, Carlos Alberto da Silva Rebelo, Rui Artur Bartólo

Engineering 2017, Volume 3, Issue 6,   Pages 795-805 doi: 10.1016/j.eng.2017.12.001

Abstract:

Different strategies can be used to perform reparations and reinforcements of ancient bolted and riveted metallic bridges. As the riveting process is not currently a common practice, it requires proper equipment and skilled workers. Another solution is the use of welding. However, the weldability of old steels is poor. Bolts are very attractive alternative solutions, and are most commonly used to repair old metallic bridges. Fitted bolts are expensive solutions; the alternative is the use of resin-injected bolts. The behavior of bolted joints with preloaded resin-injected bolts has been studied using quasi-static and creep tests; however, few studies on the slip and fatigue behavior of these joints can be found in the literature. This paper presents an overview of a few experimental programs that were carried out by several authors aiming at evaluating the fatigue behavior of single and double shear resin-injected bolted connections. A comparison between the experimental data of joints with preloaded standard bolts and preloaded resininjected bolts shows a fatigue strength reduction in the latter. Since Eurocode 3 (EC3) suggests the same fatigue strength curve for joints made of resin-injected bolts and standard bolts, this may raise some concerns. Furthermore, research on the feasibility of using both bonded and bolted connections is shown. This last study was performed with high-strength low-alloy structural steel plates and an acrylic structural adhesive for metal bonding. For both case studies, a statistical analysis is performed on fatigue experimental data using linearized boundaries and the Castillo and Fernández-Canteli model. Fatigue design curves are proposed and compared with the design suggestions of several European and North American standards.
