Sink mark degrades the surface quality of the thick-walled injection molded components. An effective method for quantifying sink marks, and predicting the occurrence of such defects as a function of the injection molding process parameters, are of significant interest in improving the molding quality. The present study proposes a method for measuring the micro-shrinkage using a simple image-processing technique. Simulation and experimental trials are performed to investigate the effects of injection molding parameters on the quality of the polymer melt (as evaluated using quality indexes extracted from the pressure profiles within the chamber and the tie-bar elongation, respectively) and the quality of the final molded component. The sink mark is determined mainly by the holding pressure. The quality indexes revealed in this study are all highly correlated with micro-shrinkage. They provide a viable means of predicting the formation of sink marks and excessive micro-shrinkage in thick-walled injection molded components. © 2022, The Authors. All rights reserved.

Environmental awareness has recently emerged as one of the most crucial topics. As a result, various groups advocate for these technologies and research ways to promote their usage in various contexts. This study examines the factors influencing the intention and use of green technology among academics. This study integrates Price Value (PV) and Consideration of future consequence (CFC) to Theory Planned Behavior (TPB) as a theoretical basis. Two hundred five valid replies were gathered and processed through statistical analysis. The results of this study partly support the developed hypotheses. Four hypotheses developed from TPB have presented significant relationships. However, PV and CFC were not. The findings indicate that individuals in this study did not consider CFC or PV of green IT products as critical factors in their decision-making process. Findings also suggest that for implementation success, competent parties must consider the campaign to increase individual awareness and provide financial support regarding environmental policy.

Gibberellic acid (GA), a crucial plant growth hormone that has a beneficial role in agriculture, faces the significant challenge of instability, hindering its effective field application. To address this, a pH-responsive hydrogel system was designed to enhance GA's stability, retention, and sustained release, thereby optimizing seed germination and plant growth. The approach involves the synthesis of hydrogel beads using dopamine-functionalized nanoporous diatom (DE-PDA) microparticles combined with GA, which are then encapsulated within alginate and chitosan matrices using an ionotropic pre-gelation technique. The hydrogels demonstrated a nanoporous network, characterized by crosslinking, hydrogen bonding, and ionic interactions. The inclusion of nanoporous DE-PDA not only fortifies the stability of GA but also improves the release profile, achieving 86.3% cumulative release by the 15th day demonstrating a substantially higher swelling rate of 1,667±36.1%. In contrast, the hydrogel system lacks DE-PDA sustained GA release for a mere 5 h with a swelling rate of 629±43.3%. Theoretical insights suggest that GA release was governed by Fickian diffusion and the polymer relaxation mechanism. Benefiting from intensive polymer interactions and the excellent biodegradability of the hydrogels, the germination rate assay using tomato seeds highlights the superior biological activity of the hydrogel, showcasing its potential for practical application in agriculture. Importantly, studies reveal that GA-encapsulated hydrogels outperform free GA in enhancing key physiological growth parameters including shoot length, stem thickness, leaf number, and shoot weight in tomato seedlings and plants, making a significant advancement in sustainable agriculture. © 2024, The Authors.

The scope of the work is to investigate limitations in device scaling by identifying various parameters of short channel effects (SCEs) in current challenging geometries of the line tunnel field effect transistors (TFETs). Key factors of the considered device, such as the doping and the thickness (tn) of n-epitaxial region, and source-to-drain length (LSDeff) scaling cannot be tuned anymore to boost the device characteristics for the sub-8-nm technology node. The main results of this study indicates that the engineering acceptable performance are achieved at a low doping of 5 1018 cm-3, an optimal tn as low (about 0.5 nm), and a LSDeff greater than 12.5 nm. Hence, the line TFETs below sub-8-nm faces serious bottleneck of scaling and cannot be further scaled with the conventional scaling rule at all. © 2020 IEEE.

AbstractObjectivesKorean mint (Agastache rugosa; KM) is a medicinal plant of the Labiatae mint family that exerts a wide range of health benefits including anti-inflammatory and antioxidants. The beneficial health effects of KM have been associated with the presence of polyphenols. However, the bioavailability of KM is still poorly evaluated to understand how bioactive compounds are absorbed and reach systemic circulation. The objective of this study was to investigate how the dominant KM polyphenols are differently available in circulation in vitro and in vivo. MethodsIn a randomized, double-blind, crossover design, 10 healthy females consumed either placebo or KM extract. Blood samples have collected before and 15, 30, 60,120, 180, and 360 min for the analysis of serum polyphenol concentration by ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). Additionally, the bioaccessibility of KM polyphenols was assessed after in vitro digestion using Caco-2 monolayers grown in permeable filter supports. ResultsThe UPLC-MS/MS analysis showed the dominant components in the extract were rosmarinic acid (RA), acacetin (AC) and acacetin 7-glucoside (tilianin, TA). Following KM extract consumption, the absorption curve of RA, TA, and AC changed over 6 h. RA and TA were most abundant 2–3 h post-initial ingestion with a gradual decrease afterward. By contrast, the appearance of AC in serum was delayed to 2 h but continuously increased until 6 h post-ingestion. In vitro data with absorptive intestinal cells indicated that AC and TA gradually decreased in the apical side, and correspondent enrichments were found in the basal side. RA was not transported in quantifiable concentration. ConclusionsThese findings suggest that KM polyphenols are readily available in circulation, providing a potential direct role in health benefits.

Current Developments in Nutrition 2022年 6卷 1166-1166页

Objectives:This study aimed to examine the protective effects of Aronia melanocarna berry extract (ABE) supplementation against the acute aerobic exercise (AAE) – induced oxidative stress in healthy subjects. Methods:A 8-week, randomized, double-blind, parallel, placebo-controlled trial were conducted with 70 healthy middle-aged adults. We assessed a battery of AAE-induced oxidate stress biomarkers at pre-exercise, immediately post-exercise, and 30-min post-exercise. The AAE challenge model, as a treadmill exercise for 30 minutes at 60% VO2max, was applied to load oxidative stress at the end of the study. A linear mixed-effect model was used to test differences of safety and effectiveness between two groups and Pearson’s correlation coefficients assessed the statistical association. Results:The AAE-induced time course-dependent oxidative stress was well-observed in the placebo group regarding the glutathione peroxidase activity and glutathione availability for antioxidant defense; and erythrocyte malondialdehyde, interleukin-6, and lactate levels for oxidative damage. Meanwhile, the ABE supplementation improved the glutathione defense system by increasing glutathione availability and glutathione peroxidase activity during exercise and post-exercise recovery periods. In addition, the scatter plot and linear regression analysis revealed strong negative correlations of GSH availability with oxidized LDL and erythrocyte malonaldehyde levels. Conclusions:These finding suggest ABE supplementation might affect to improve antioxidant defense mechanism in healthy adults with low fruit and vegetable intake. Funding Sources:This research was supported by the BK21 FOUR (Fostering Outstanding Universities for Research) funded by the Ministry of Education (MOE, Korea) and the National Research Foundation of Korea (NRF), and the Bio & Medical Technology Development program of the National Research Foundation (NRF), funded by the Ministry of Science & ICT (2012M3A9C4048761).
