Guanyin can also freely change into many incarnations. Starting from the 2nd century A.D., Guanyin began to appear as a woman, becoming one of the most important images in Chinese Buddhism. This statue of Guanyin was excavated in 1955 from the ruins of Dadu (the capital of the Yuan Dynasty) at Dingfu Street, Xicheng District of today’s Beijing. It stands 67 cm high. Smiling slightly with her half-lidded eyes, Guanyinlooks dignified and refined, with a some-展开更多

L-arabinose is mainly produced by chemical or enzymatic hydrolysis of hemicellulose. The taste of L-arabinose is quite similar to that of sucrose, with approximately 50% of the sweetness. As a functional additive, L-arabinose can be used in medical and pharmaceutical applications for the treatment of diseases such as diabetes, chronic constipation, mineral absorption disorder and secondary bile acid formation disorder. However, L-arabinose has not been widely used in functional foods due to high price and lack of publicity and guidance. A comprehensive review of L-arabinose physicochemical properties, production, applications field, market statue and development direction is presented in this paper.展开更多

The idea of extending the CapitoLine Museums by incLuding this site came about in the framework of its general redevelopment.1 The new HaLL is the result of a Long and compLicated process （1988-7005） considering the exceptional importance of the site and the many changes brought to the museum programme during the said period （Figures 1 and 2）.In fact, the new HaLL was originaLLy supposed to display the marbLes of the TempLe of ApoLLo Sosianus, the foundation waLL of the TempLe of CapitoLine Jupiter, embedded within the structures of the PaLazzo CaffareLLi, opposite the Giardino Romano. However, in 1997, the plan for the CapitoLine Museum changed radicaLLy as the statue of Marcus AureLius, which had been restored foLLowing the bLast of a bomb attack in 1979, was determined to be the focus of the HALL. The project finaLLy consisted of a steeL and gLass structure on an eLLiptic plan andshaped around the foundations of the TempLe, with the statue at its center.展开更多
