Results are comparable to experimentations. Based on results of both NPY and its model, N-(2-hydroxy-l-naphthyl-methylene)aniline, it was found that the N-(2-hydroxy-l-naphthyl-methylene) group is principally responsible for the special hydrogen bonding through conjugation effect.展开更多

A multidisciplinary team consisting of an occupational therapist, a physiotherapist, a medical doctor practising symbolic drama and a nurse with gardening experience provided NBR in an agricultural environment. Patients were offered 14 weeks of rehabilitation in a group of eight persons, three mornings per week. Seventeen patients participated in the study and 15 completed the study. A semi-structured interview was conducted at the beginning of the rehabilitation and at the end and a follow-up interview by telephone was done one year after completion of the rehabilitation. The interviews were recorded and transcribed. Assessment scales used included: Stress and Crisis Inventory (SCI-93), Coping Resources Inventory (CRI) and Visual Analogue Scale (VAS). Weekly notes from the staff members were reviewed and compared with the patient’s own experience. The interviews and the staff notes were analysed with semantic thematic analysis. Result showed that this kind of NBR with a multidisciplinary team promotes improved health and improved quality of life for patients with ED and may thus constitute a good alternative to treatment, provided the ED has not become chronic.展开更多

Changes in natural resource restrictions are challenging the future sustainable development of the regional economy. Here, we propose a new concept called Natural Resource Regulation on Regional Economic Development （NRR）. NRR is an application of government regulation to natural resources, aimed at regulating and controlling regional development. It is a set of constraints on the exploration, exploitation, utilization, operation and protection of natural resources carried out by government. This concept focuses on two aspects： the management of natural resources, and using natural resources as a tool to regulate and control the regional economy and social development. NRR mainly consists of four layers： regulation by law （RL）, regulation by plans （RP）, regulation by standards （RS） and concrete regulation by control indicators （RI）. In addition, social participation and supervision, monitoring and evaluation, rewards and punishments are also indispensable for the framework of NRR. According to the types of resources, practical regulation of land, water, energy and environment are stricter than that of marine, mineral and forest in China. The systems of RL, RP and RS in China are basically established and have achieved considerable results, while concrete RI is still fragmented.展开更多
