Heavy oils induced water pollutions are difficult to be eliminated due to the oils located under water. Herein, wefabricated superhydrophobic cellulose film with nanoflower structures via a Facile method to eliminate heavy oil from water. Cellulose films were in-situ modified with Fe2O3 and stearic acid (STA) for superhydrophobic modification. Thecorresponding superhydrophobic cellulose/Fe2O3-STA film has water contact angle of 155.5 º and sliding angle of 5.5 º, andcan maintains its superhydrophobicity when it is immersed in water. The film exists excellent self-cleaning property, and thedusts on the film could be easily swept away by running water drops. The film was further applied to separate heavy oil/watermixture with separation efficiency of 99.37 %, and the separation efficiency was maintained after 20 separation cycles aswell. The film can also be utilized to absorb small heavy oil drops under water. Thus, we not only develop a simple way toproduce superhydrophobic cellulose based films, but also provide superhydrophobic materials to solve water pollutioncaused by heavy oil.

<P><B>Abstract</B></P> <P>Protecting building, critical infrastructure and military vehicles from Improvised Explosive Devices (IEDs) has become a critical task. This study aims to examine the performance of a new protective system utilizing auxetic honeycomb-cored sandwich panels for mitigation of shock loads from close-in and contact detonations of high explosives. Both field blast tests and drop weight tests were performed using the proposed sandwiches asa shield for concrete panels in combination with conventional steel protective plates. The combined shield was found to be effective in protecting reinforced concrete structures against severe impact and close-in blast loadings. The honeycomb core with re-entrant hexagonal cells shows evident auxetic characteristics which contribute substantially to outstanding force mitigation and blast-resistance performances of such sandwich panels. Numerical simulations showed good agreement with the experimental results. The proposed auxetic panels were found to perform better than conventional honeycomb panels of the same size, areal density and material. Both were found to boost the energy absorption of the monolithic steel plate by a factor of 2.5 by changing its deformation pattern under close-in blast loading. In addition, a combination of the steel plate and an auxetic sandwich panel has aerial specific energy absorption (<I>ASEA</I>) higher than either of them, showing great potential for the development of lightweight blast protection of civil, mining, military, nuclear infrastructure and vehicles.</P>

Growth and Union Acclimation Process of Sweet Pepper Grafted by a Tubing-Grafting Robotic System
Yung-Chiung Chang,Suming Chen,Yi-Chich Chiu,Lian-Hsiung Lin,Yu-Sen Chang 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.2
Sweet pepper ‘Andalus’ (Capsicum annuum L. ‘Andalus’) was grafted on chili pepper ‘P’ (Capsicum chinense ‘P’) by hand and by using a tubing-grafting robotic system. After grafting, the growth and condition of the seedlings grafted by machine were similar to that of the seedlings grafted by the traditional hand method. Although the cut interfaces on the mechanically grafted seedlings were more irregular, seedlings’ acclimation process was similar to that of those which had been grafted by hand. This indicates that the tubing-grafting robotic system can be applied generally to grafting operations, thus allowing improvements in production efficiency.
Temperature Effects on Shoot Growth and Flowering of Kumquat Trees
Yung-Chiung Chang,Iou-Zen Chen,Lian-Hsiung Lin,Yu-Sen Chang 한국원예학회 2014 원예과학기술지 Vol.32 No.1
This study investigated the effects of temperature on the shoot growth and flowering of potted kumquat [Fortunella margarita ( Lour.) Swingle] trees grown in subtropical conditions of I-Lan County in Taiwan. Temperature treatments included T 25-32, T 17-25, T 22, and T 18. The T 25-32 treatment trees were to the day/night temperatures of 25/18°C for 2 weeks, followed by 28 weeks at 32/25°C. T 17-25 was exposed for 4 weeks to 17/10°C followed by 26 weeks at 25/18°C. T 22 and T 18 were exposed at 22/18°C and 18/13°C, respectively, for the entire duration of the experiment. Control trees were placed in a plastic greenhouse under conditions similar to the natural environment. The kumquat trees exposed to high-temperature environment of 32/25°C showed more frequent and speedy sprouting of new buds, but induced the earlier termination of shoot elongation growth, resulting in decreased vegetative growth. The temperature treatments lower than 22°C suppressed the new shoot production but increased the shoot growth period, resulting in increased shoot length and diameter. Temperatures higher than 25/18°C readily induced flowering, with flowering being advanced under the higher temperature conditions such as 32/25°C. However, flowering was substantially inhibited under temperature conditions lower than 22/18°C, indicating the negative role of relatively lower temperatures on flowering of kumquat trees.

Yung-Chiung Chang,Yu-Sen Chang,Iou-Zen Chen,Lian-Hsiung Lin 한국원예학회 2020 원예과학기술지 Vol.38 No.2
This study investigated phenological changes, shoot growth, and flowering habits of potted kumquat[Fortunella margarita (Lour.) Swingle] grown in subtropical conditions of I-Lan County, Taiwan. The shoots of the second, third, and fourth flushes of kumquat sprouted in mid-May, early July, andearly September, corresponding to 70-80, 112-122, and 168-178 days after the buds sprouted fromthe first flush, respectively. As the flushing sequence progressed, the number of shoots, the rate offlowering, and the number of flowers decreased. There were four flowering peaks in 2010 and fivein 2011. The shoots of the secondary and tertiary flushes still bloomed in 2010, but they did notflower in 2011. In 2011, the second flowering period of the first flush shoot, which flowered inmid-July, fruit set, and fruit growth showed the best performance, and the whole fruit developmentduration took about 169 days.

The objective of this study was to determine the level of regulated deficit irrigation (RDI) for the potted ‘Nagami’ kumquat culture. Three treatments, control, RDI 1, and RDI 2, representing 75, 55, and 35% of available soil water content, respectively, were implemented for two weeks after the elongation of the newly-sprouted shoots (the first flush) was nearly terminated. Leaf water potential, leaf photosynthetic activity, shoot vegetative growth, flowering, and fruiting were monitored to evaluate the effects of the RDI treatments. After water withholding for two weeks (stage B), trees treated with RDI 2 decreased considerably in their leaf water potential, and exhibited the highest integrated leaf water potential index, which indicated that their leaves had suffered from the highest level of stress. The net CO2 assimilation rate (Pn) and available fluorescence (Fv)/maximum fluorescence (Fm) and Fv’/Fm’ ratios also decreased substantially in RDI 2-treated trees. However, the stressed trees exhibited compensatory growth, and all growth parameters returned to normal following re-watering. RDI 2 treatment increased flowering potential of the trees, showing the highest average flowering ratio of 50%, which differed substantially from that of the control and RDI 1. No significant differences were observed between the responses of RDI 1 and control, indicating that both treatments were not severe enough to induce a visible physiological effect in trees. By contrast, RDI 2 treatment efficiently changed the shoot growth phase and increased the number of flowers on the shoots, which may be exploited as an efficient approach for kumquat flowering control.
Research on bearing characteristics of socket-spigot template supporting system
Chang-Ming Hu,Yan Guo,Ming Lian 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.20 No.4
The socket-spigot template supporting system is widely used in engineering applications in China. As a newer type of support structure, there has been growing research interest in its bearing capacity. In this paper, four vertical bearing capacity tests were carried out on the basic mechanical unit frame of a socket-spigot template supporting system. The first goal was to explore the influence of the node semi-rigid degree and the longitudinal spacing of the upright tube on the vertical bearing capacity. The second objective was to analyze the displacement trend and the failure mode during the loading process. This paper presents numerical analysis of the vertical bearing capacity of the unit frames using the finite element software ANSYS. It revealed the relationship between the node semi-rigid degree and the vertical bearing capacity, that the two-linear reinforcement model of elastic-plastic material can be used to analyze the socket-spigot template supporting system, and, through node entity model analysis, that the load transfer direction greatly influences the node bearing area. Finally, this paper indicates the results of on-site application performance experiments, shows that the supporting system has adequate bearing capacity and stability, and comments on the common work performance of a socket and fastener scaffold.

Breast capillary hemangioma is a type of benign vascular tumor which is rarely seen. Little is known about its presentation on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Here, we describe a case of suspicious breast lesion detected by DCE-MRI and pathologically confirmed as capillary hemangioma. Our case indicates that a small mass with a superficial location, clear boundary, and homogeneous enhancement on DCE-MRI indicates the possible diagnosis of hemangioma, whereby even the lesion presents a washout type curve.
