In 1998, the current Institute of Catalysis was re-established through the merger of Zhejiang University and Hangzhou University et al. During the past forty years, researchers in Institute of Catalysis had always paid much attention to the combination of fundamental researches and industrial applications under the lead of Songshou Jin, Xiaoming Zheng, Weimin Lu, Hui Lou, and Yong Wang. The major research interest includes:(1) basic application research and exploitation of catalysts and catalytic process regarding conversion of biomass, methane, syngas and carbon dioxide;(2) development of catalysts and reaction apparatus for industrial hazardous gas, indoor gas, vehicle emissions and oil smoke from hotels and restaurants;(3) synthesis, characterization of functional materials and their applications in the green synthesis in fields of medicine, pesticide and fine chemical;(4) heterogeneous and homogeneous catalytic reaction kinetics and surface chemistry;(5) catalytic researches regarding military project.展开更多

In this paper, with the campus planning and design as an extension as well as the blending and symbiosis between urban historical culture and natural scenery as the focus of attention, the Chinese thinking pattern stressing prefect harmony and in-depth dialogue between culture and nature is expected to be applied to the construction of modern cities to build and improve the "Shanshui city" planning system so that the planning concept that Chinese thought, "unity of man and nature", is used to build modern cities is carried forward.展开更多

Solid waste is mainly from urban garbage and industrial waste. Sludge is from water treatment factories, paper mills, chemical factories, pharmaceutical factories, rivers and lakes. The waste and sludge are very harmful to water organisms, human health and drinking water, and directly affect the environment. Sludge and waste also occupy large areas of land. There are several methods to treat waste and sludge, such as burial, chemical treatment and incineration. Incineration is more effective than the展开更多

Although the known facts of the benefits of F & V on health, information on Saudi society following the advised recommendation whether by WHO or local are still unknown. Aim: This cross-sectional study aims to examine the perception of F & V intake among students at Umm Al-Qura University and to assess if they follow these recommendations of F & V locally and internationally. Method: Students from Umm Al-Qura University participated in this study (n = 98, age between 18 - 55). All data were collected using short online survey via Online survey—Survey Monkey in 2019. Result: 55% students were not aware of these recommendations whereas 45% were aware of WHO recommendation. The majority of students 53% have less than two portions a day of F & V. Only 14% have between two to four portions a day. 32% do not eat any portion of F & V daily. 59%, 14%, 5% of students believe that they should have five, seven, more than seven portions a day for being healthy respectively. Maintaining health, reducing the risk for chronic disease and providing essential vitamins and minerals to the body were all reasons why students believe that they should have F & V everyday by 71%. Busy lifestyle, F & V cost, lack of the awareness about the health benefits, dislike of the taste, some F & V spoiled easily were all factors affecting eating F & V daily. Conclusion: University students need educational and nutritional campaigns to spread the awareness about the health benefits of F & V. Most importantly the ministry of health should support those campaigns to increase students’ awareness and build a healthy society with a good habit.展开更多

Their spatial combinations reflect that the developments of Danxia landform have undergone stages of geomorphic cyclical erosion in the form of weathering, collapse, transportation, sedimentation and other processes, together with the "sculpture" of external forces mainly as tectonic uplift. The picturesque Danxia landform began its formation at that point. Danxia landform developed mainly in the strata of Fangyan Formation (K1f) caused by the alluvial fan-braided river phase of anterior fan in the late period of the Early Cretaceous. Regular patterns of weathering of stones and features of braided alluvial phase sediments may be verified by the analysis of three groups of experimental data. Danxia landform of Fangyan is a unique representative of the "adolescent" development type in the application of the World Natural Heritages status in China, by virtue of its outstanding universal aesthetic and scientific value.展开更多

We use f (R,T ) = R + 2μT , where R is the Ricci scalar, T is the trace of energy-momentum tensor and μ is a constant. Two cosmological models are constructed using the power law expansion and hybrid law cosmology in Bianchi type I universe, where the matter field is considered to be a perfect fluid. It is found that in both the cases the anisotropic behavior is in agreement with the observational results. The state finder diagnostic pair and energy conditions are also calculated and analyzed.展开更多
