Total syntheses of 22-hydroxyacuminatine and luotonin A were achieved in direct fashion and high overall yields (16% in eight steps and 47% in five steps, respectively). A mild cascade methodology was successfully applied in both syntheses as a common strategy. The new approach presents the advantages of short routes, high overall yields, use of stable(More)
Reducing moisture in sewage sludge is one of the main goals of sewage sludge composting and biodrying. A mathematical model was used to simulate the performance of water removal under different aeration strategies. Additionally, the correlations between temperature, moisture content (MC), volatile solids (VS), oxygen content (OC), and ambient air(More)
A recyclable plastic bulking agent (RPBA) that can be screened and reused was developed to improve sludge composting and to reduce costs. Two RPBAs were developed: RPBA35 (35 mm in diameter) and RPBA50 (50mm in diameter). The objective was to study the influence of size and quantity of RPBA on temperature, oxygen content, water removal during sludge(More)
OBJECTIVE To study relationships between serum ferritin and bone metabolism in patients with hip fragility fractures. METHODS This cross-sectional study included 76 postmenopausal women with hip fracture from Feburary 2011 to June 2012. The mean age of the women was (73 ± 10) years (range, 55-93 years) and the mean duration of menstruation was (22 ±(More)
Femoral midshaft fracture is one of the most common clinical injuries and is often caused by high-energy traffic accidents. Intramedullary nailings, plates, and external fixators are all used as treatment alternatives for a variety of patients depending on fracture location, displacement, comminution, soft tissue condition, and local tradition. Locked(More)
OBJECTIVE To evaluate clinical outcome after anterior cruciate ligament (ACL) reconstruction with double-bundle or single-bundle by meta-analysis. METHODS Randomized controlled trials (RCTs) on differences of clinical outcomes of ACL reconstruction were retrieved in Ovid Medline, PubMed, Embase, Cochrane Library, CBM and VIP database. Relevant journals or(More)
A mild and efficient cascade methodology is reported to construct variously substituted indolizino[1,2-b]quinolin-9(11H)-ones. Efficiently triggered by bis(triphenyl)oxodiphosphonium trifluoromethanesulfonate under mild conditions, this cascade achieved significant enhancements in chemical yields. Utilizing this highly efficient domino reaction followed by(More)
OBJECTIVE To investigate the feasibility and safety of early dressing removal of clean wounds following thoracotomy. SUBJECTS AND METHODS A total of 230 patients (127 males, mean age 55.6 ± 16.7 years) were randomly divided into study and control groups. In the study group the cotton gauze dressing was removed 48 h after the surgery, whereas in the(More)
In this paper, the property right of counseling service assessment is innovatively proposed, which can promote the authority and impartiality of that assessment. Basing on the models of Expectation Gap Model, the Value of Knowledge Evaluation Model and Multi-factors of Correction Evaluation Model, this paper probes into the method of assessing counseling(More)
