Soil respiration (SR) Wis one of the largest contributors of terrestrial CO_2 to the *** as well as physicochemical parameters influence SR and thus, different land use practices impact the emissions of soil CO_2. In this study, we measured SR, bi-monthly, over a one-year period in a terrace tea plantation, a forest tea plantation and a secondary forest, in a subtropical mountain area in Xishuangbanna, China. Along with the measurement of SR rates, soil characteristics for each of the land use systems were investigated. Soil respiration rates in the different land use systems did not differ significantly during the dry season, ranging from2.7±0.2 μmol m^(-2) s^(-1) to 2.8±0.2 μmol m^(-2) s^(-1). During the wet season, however, SR rates were significantly larger in the terrace tea plantation(5.4±0.5 μmol m^(-2)s^(-1)) and secondary forest(4.9±0.4 μmol m^(-2)s^(-1)) than in the forest tea plantation(3.7±0.2 μmol m^(-2) s^(-1)).This resulted in significantly larger annual soil CO_2 emissions from the terrace tea and secondary forest,than from the forest tea plantation. It is likely that these differences in the SR rates are due to the 0.5times lower soil organic carbon concentrations in thetop mineral soil in the forest tea plantation, compared to the terrace tea plantation and secondary ***, we suggest that the lower sensitivity to temperature variation in the forest tea soil is a result of the lower soil organic carbon concentrations. The higher SR rates in the terrace tea plantation were partly due to weeding events, which caused CO_2 emission peaks that contributed almost 10% to the annual CO_2 flux. Our findings suggest that moving away from heavily managed tea plantations towards low-input forest tea can reduce the soil CO_2 emissions from these systems. However, our study is a casestudy and further investigations and upscaling are necessary to show if these findings hold true at a landscape level.

This paper presents dynamic modeling of 1000 W EC6C Proton Exchange membrane fuel cell (PEmFC) manufactured by Edibon. Experiments were carried out to investigate the performance of the system and a dynamic electrical model was implemented in matlab/Simulink. The simulation model was able to predict efficiency, power and fuel cell potential. The model was also tested with load variations to find out the real time responses. The results were validated by experimental findings. The comparison showed that the model was effective and could be used in optimization of the fuel cell system operated at low temperatures under 80 degrees.

Objective: Equine-assisted activities and therapies(EAATs) have been a growing adjunctive integrative health modality, as they allow participants to practice mindfulness, emotional regulation, and self-mastery or self-esteem building skills. Preliminary evidence suggests that these programs may be helpful in reducing posttraumatic stress disorder(PTSD), anxiety, and depressive symptoms. The current study examines the acceptability of integrating an EAAT program as part of a two-week, intensive clinical program for veterans with PTSD and/or traumatic brain injury(TBI).methods: A family member or support person could accompany veterans and participate in the *** hundred and six participants(veteran n = 62, family n = 44) left the urban environment in an intensive outpatient program(IOP) to attend a two-day, weekend EAAT in rural New Hampshire. Satisfaction surveys were conducted on the last day of the program and examined using thematic ***: The following themes were reported in the surveys: ability of horses to catalyze emotional rehabilitation, effectiveness of immersion in equine-assisted activities, program’s ability to foster interpersonal relationships and necessity of education about PTSD for staff. Participants also reported enjoying the program as highlighted by qualitative feedback, a mean score of 9.76(standard deviation[SD] = 0.61) as reported by veterans and a mean score of 9.91(SD = 0.29) as reported by family members on a 10-point visual analog scale with higher scores indicating a greater overall ***: These data offer preliminary evidence that an adjunct EAAT program is acceptable for veterans with PTSD and/or TBI participating in an IOP.

State of the Art Priciples in Shoulder Rehabilitation

引用

中国康复医学杂志 2003年第7期18卷 393-397页

作者： edward R.Laskowski m.D. mayo Clinic Sports medicine Center Associate ProfessorMayo Medical SchoolCo-Director

The primary goal of shoulder rehabilitation is to restore optimal pain-free shoulder function. In general terms, shoulder rehabilitation involves control of pain and inflammation,early non-traumatic motion, muscle reactivation, strengthening of shoulder group muscles, and restoration of normal shoulder function within the kinetic-kinematic chain. Finally, sports and activity-specific rehabilitative exercise are essential to maximize function and return the patient to their prior sport or activity without deficit. This discussion will review recent research findings that have expanded our knowledge and understanding of shoulder function and which will serve as guidelines for a state-of-the-art shoulder rehabilitation program.
