The protective effect of cyclodextrin on the color quality and stability of Cabernet Sauvignon red wine

The impact of cyclodextrins(CDs)on wine quality and stability remains largely unknown.This study systematically assessed the protective effect of the post-fermentation addition of CDs on color stability of red wine from the viewpoints of color characteristics,copigmentation and phenolic profiles.The grey relational analysis(GRA)and principal component analysis(PCA)methods were employed to dissect the key effective determinants related to color quality.The addition of CDs induced a significant hyperchromic effect of 8.19-25.40%,a significant bathochromic effect and an enhancement of the color intensity.Furthermore,the evolution of anthocyanin forms and the content of monomeric anthocyanins revealed that β-CD is a superior favorable cofactor during wine aging,but for long-term aging,2-HP-β-CD and 2-HP-γ-CD are more beneficial in promoting the formation of polymerized anthocyanins and color stability.This work provides an important reference for the use of CDs to enhance the color quality and stability of red wines.

Experimental Study of the Interaction between Building Clusters and Flash Floods

In recent years, flash flood disasters have occurred frequently in southwest China due to the increased frequency of extreme climate events. To solve this problem, great efforts have been made in studying the process of flash flood. However, little attention was paid on bearing body of hazard, the clusters of buildings. Thus the real disaster mechanism of flash flood remains unclear.Accordingly, based on the experiments of artificial flash floods in a conceptual solid model, this paper focuses on the flood-impacted inundation characteristics of the building clusters at different locations of the gully model, in order to obtain a better understanding of the disaster process and the interaction between the flash floods and building clusters. The results showed that, in a typical smallscale flash flood gully with hot and dry climate, 1)clusters of buildings on an alluvial fan could reduce about 35% of the flooding area by blocking the diffusion of the flood to the depression areas, and could also promote the deposition in lower reaches of the river channel by blocking the overbank flow from going back into the channel, making the width-depth ratio of the channel larger. 2) The flash flood rates of disaster and hazard on the alluvial fan are generally higher than that of the inner gully. For the inner gully,buildings located on the beaches along the lower river and the transitional areas of the straight channel and channel bends can easily be affected because of their lower elevations. For the alluvial fan, buildings nearby the meanders suffer the greatest impacts because of bank collapsing and flooding. 3) The safe vertical distance from a building to the river channel is 13 m for the buildings in the inner gully under extreme floods. Below this threshold, the smaller the vertical distance is, the greater the risk exposure is. For the buildings on the alluvial fan, especially for the buildings near the concave bank of the top rush point,the horizontal distance is more important, and the safe value is 80 m under extreme floods.

Effects of a Building’s Density on Flow in Urban Areas

The effects of a building＇s density on urban flows are investigated using a CFD model with the RNG k - ε turbulence closure scheme. Twenty-seven cases with different building＇s density parameters （e.g., building and street-canyon aspect ratios） are numerically simulated. As the building＇s density parameters vary, different flow regimes appear. When the street canyon is relatively narrow and high, two counterrotating vortices in the vertical direction are generated. The wind speed along streets is mainly affected by the building＇s length. However, it is very difficult to find or generalize the characteristics of the street-canyon flows in terms of a single building＇s density parameter. This is because the complicated flow patterns appear due to the variation of the vortex structure and vortex number. Volume-averaged vorticity magnitude is a very good indicator to reflect the flow characteristics despite the strong dependency of flows on the variation of the building＇s density parameters. Multi-linear regression shows that the volume-averaged vorticity magnitude is a strong function of the building＇s length and the street-canyon width. The increase in the building＇s length decreases the vorticity of the street-canyon flow, while, the increase in the street- canyon width increases the vorticity.

A novel approach for assessing color harmony of historical buildings via street view image

While new buildings continue to emerge in the process of urbanization,historical buildings,as valuable legacies carrying national historical memory,play an important role in the urban landscape.Previous studies have shown that color harmony is a crucial factor in coordinating urban landscapes.However,the evaluation of color harmony in historic areas and buildings lacks effective quantitative standards,often overlooking factors such as complementary color harmony and the compatibility of analogous colors.This study aims to build a new method to evaluate the color harmony of historical buildings through street view technology,semantic segmentation algorithms,quantification of color harmony methods based on image property detection and classification,questionnaire verification,and takes Shanghai’s historical buildings as an example to explore.Our study categorizes six types of color harmony indexes for Shanghai street-facing historic buildings into three levels,with the top tier serving as a benchmark for excellence and the lowest tier highlighting areas in need of urban environmental improvement.This study uniquely considers color compatibility within hue ranges and expanded relationship types like complementary harmony.This approach,applicable to cities globally,offers practical tools for urban planners and conservators in managing and preserving historic areas and buildings.

Student capacity building of dengue prevention and control: A study of an Islamic school, Southern Thailand

Dengue has been a critical problem for an Islamic School, Nakhon Si Thammarat province, Southern Thailand. Objectives: 1) to build student capacity;and 2) to evaluate the results of student capacity building. Method: Participatory Action Research: PAR was applied in three phases: 1) the school-based preparation phase;2) the process of building student capacity phase, and 3) evaluation of the results of the student capacity building. Independent T-Test statistical method was used to analyze student capacity both before and after the intervention. Larval Indices were determined through ratio analysis. Results: Prior to the intervention, there was no clear strategy for combating dengue. In this study, three groups were formed to build student capacity: a leader group, a non-leader group, and a support group. The leader group (48 student leaders), critical to the study, was set as a dengue club named “Eliminate Ades Aegypti, the culprit of dengue” which focused on eight sets of activities: “Dengue or Death”, “Seniors educating juniors”, “Reward for good answers”, “Dengue monitoring team”, “Youth to expel mosquetoes”, “Mosquito or busy”, “Garbage elimination of Pondok”, and “Essential doctors”. The level of student capacity for the prevention and control of dengue of a sampling of 308 student representatives of the Pondok (Islamic school) showed an increase after intervention ( (SD);56.78 (17.06);65.33(15.36) and different statistic significant (P < 0.001). The Larval indices ratio levels had decreased from the original levels (BI = 244, HI = 45, and CI = 26) after intervention (BI = 137, HI = 39, and CI = 19). Dengue morbidity and mortality rates were not found during the study. Discussion: Although there had been an increase in student capacity, a decrease in the larval indices ratio, and the absence of a dengue epidemiology index, the high risk of a dengue epidemic might still be found in the school because the ratio of larval indices were higher than the standard index. Then, the committed participation of students, school, and communities around the school vicinity is needed in building student capacity of dengue prevention and control.

INFLUENCE OF UNCERTAINTY OF ROCK PROPERTIES ON SEISMIC RESPONSES OF REACTOR BUILDINGS

The influence of the dispersion and uncertainty of the dynamic shear wave velocity and Poisson＇s ratio of soil in a hard rock site was investigated on the seismic response of reactor building structure. The analysis is performed by considering the soil-structure interaction effects and based on the model of the reactor building in a typical pressurized water reactor nuclear power plant （NPP）. The numerical results show that for the typical floor selected, while the relative increment ratio of the dynamic shear wave velocity varies from -30% to 30% compared to the basis of 1 930 m/s, the relative variation of the horizontal response spectra peak value lies in the scope of ±10% for the internal structure, and the relative variation of the frequency corresponding to the spectra peak is 0.0% in most cases. The relative variation of the vertical response spectra peak value lies in the scope of - 10% to 22%, and the relative variation of the frequency corresponding to the Spectra peak lies in the scope of - 22% to 4%. The analysis indicates that the dynamic shear wave velocity and the Poisson＇s ratio of the rock would affect the seismic response of structure and the soil-structure interaction effects should be considered in seismic analysis and design of NPP even for a hard rock site.
