农业废弃物,如西米废弃物对土壤和水体的污染存在潜在威胁。为了减轻这一问题,本研究对3种不同处理的西米来源的废弃物的堆肥和西米来源的腐植酸的化学性质进行了研究。在大小为61.5×49×33.5cm的白色聚苯乙烯盒子里堆置60d,通过pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸等指标对其进行分析。所有处理都没有达到高温阶段。与处理T1、T3相比,处理T2(pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸)质量更好。T2的腐植酸产量也明显比其他两组高。T1和T3的堆肥特性相似。3种处理中的腐植酸化学特性在其他研究者报道的标准范围之内。与处理T1、T3相比,在60d里,T2处理更能有效地生产成熟、高质量的堆肥。

阿拉伯半岛和中国的文明对话源远流长,地理、经济、文化上的因素决定了两个地区为了全人类的共同利益而相互交流、融合的必然性,两地的交流往来自公元651年正式开始以来便从未间断.本文以阿拉伯文、中文文献以及实地调查资料为基础,对伊斯兰教兴起至20世纪初阿拉伯半岛和中国往来的历史进行回顾,并希望通过本文的研究证实中国一海湾关系在最近十年的有力恢复是双方关系的一种常态.

This article presented the automatic diagnosis of liver pathologies and its 3d volume rendering. The first and fundamental step in all these studies is the automatic liver segmentation, which is still an open problem. In this thesis, two automatic methods are described to segment the liver from abdominal CT image data. The first step is image enhancement. Secondly, texture analysis is using standard statistical measures, finally it is a rough mask to segment the liver.

AIM: To establish whether d-limonene can protect against induction of cyclobutane pyrimidine dimers(CPds) and sunburn in ultraviolet irradiation(UVR) irradiated mouse skin. MeTHOdS: The d-limonene was given in 4 daily oral 20 μL aliquots at different concentrations as follows: 100%, 10% or 1% in liponate and 100% liponate as control. One day after the final d-limonene treatment, the mice were anesthetized with i.p. sodium pentobarbital and placed in boxes to allow a rectangular(2 cm × 4 cm) region of dorsal skin to be irradiated with a single, ultraviolet radiation dose of 1.5 kJ /m2. Skin samples from UVR irradiated area were obtained at 5 min after UVR exposure for CPd detection, at 6 d after UVR exposure, skin samples were obtained for in situ analysis for N-myc downstream regulating gene 1(NdRG1)(a stress response gene), proliferating cell nuclear antigen(PCNA)(an S-phase marker) and filaggrin(a barrier integrity gene). Based on immunohistochemistry staining, the number of CPd, NdRG1 and PCNA positive cells, as well as unstained cells was counted in 3 different individually selected areas and percentage of positive cells was established. ReSULTS: CPd reduction occurred as follows: liponate only-none; 1% d-limonene-54.3% reduction of CPds; 10% d-limonene-73.4% reduction of CPds; 100% d-limonene-86.1% reduction of CPds, the latter equivalent to a UV dose of only 0.21 k J/m2. Sunburn was also dose-dependently reduced by d-limonene. The NdRG1 protein was strongly induced by UVR(70.0% ± 10.4% positive cells), but 1% d-limonene reduced the response to 64.6% ± 9.2%, 10% d-limonene reduced the response to 16.2% ± 3.4% and 100% d-limonene reduced the response to 6.3% ± 1.7%. Similarly, PCNA was 52.4% ± 9.9% positive in UVR exposed skin, and 1% d-limonene reduced it to 42.9% ± 8.1%, 10% d-limonene reduced it to 36.2% ± 6.7% and 100% d-limonene reduce it to 13.8% ± 3.4%. NdRG1 and PCNA were increased by d-limonene or UVR separately, but combined they produced less than eit

Bacterial endocarditis following atrial septal defect closure using Amplatzer device in a child is extremely rare. We report a 10-year-old girl who developed late bacterial endocarditis, 6 years after placement of an Amplatzer atrial septal occluder device. Successful explantation of the device and repair of the resultant septal defect was carried out using a homograft patch. The rare occurrence of this entity prompted us to highlight the importance of a closed long-term follow up, review the management and explore preventive strategies for similar patients who have multiple co-morbidities and a cardiac device. A high index of suspicion is warranted particularly in pediatric patients.

Purpose: To present techniques and results of surgical repositioning of subluxed and dislocated capsular tension rings (CTRs). design: Retrospective interventional case series. Participants: eleven patients with a previously implanted CTR in-the-bag for zonularweaknesswho presentedwith CTR-intraocular lens (IOL)-capsular bag decentration who underwent surgical repositioning. Methods: data from 11 patients who underwent surgical repositioning were evaluated retrospectively for underlying diagnosis, interval between initial surgery and decentration, surgical technique, clinical results, and complications. Main Outcome Measures: Capsular tension ring-IOL-capsular bag centration, final best-corrected visual acuity (BCVA), and surgical complications. Results: Of the 11 patients with CTR decentration, 3 had it early in the postoperative period, and 8 had it late. Mean (±standard deviation) durations from cataract extraction and CTR implantation to surgical repositioning were 6.1±7.9 months for those with decentration early and 49.6±15.3 months for late decentrations (overall range, 0.7-74.7). Of the 11 patients, 7 had pseudoexfoliation, and 4 of the 7 had associated glaucoma. Nine patients had subluxation of the CTR-IOL-capsular bag complex, which was managed by an anterior segment approach. A pars plana vitrectomy and levitation of the CTR was required in 2 patients due to complete dislocation of the CTR into the posterior vitreous. Surgical techniques for repositioning included single, double, or 3-point scleral suture loop fixation of the CTR through the capsular bag complex (8 eyes); use of the capsular tension segment (CTS) placed within the capsular bag for scleral suture fixation (2); or iris suture fixation of the IOL haptics (1)-. All patients achieved successful anatomical repositioning of the CTR-IOL-capsular bag complex. Mean preoperative BCVA improved from 20/100 to 20/40 postoperatively. After repositioning surgery, BCVA improved in 7 patients, was maintaine
