Inform consent is a major objective in the relation patient–physician. Patient's information becomes doubt when it is insufficient. To answer to medical persons asking about patient's information, pretreatment clinical and paraclinical assessment will be discussed. Reflexion delay, surgical alternative therapy and pre-operatory examination will be exposed. Several critical situations, such as associated hysterectomy, patient's comorbidity (tobacco, obesity) or synthetic mesh reinforcement have to be well-known to inform patient about failures and outcomes. 相似文献

Polychlorinated biphenyl (PCB) concentrations, profiles, and possible sources were determined in the atmosphere of Guangzhou,
the largest city in south China. ∑PCB concentrations ranged from 160 to 2720 pg/m3, which is comparable with values found by similar studies in North America, Europe, and Asia. The highest PCB concentrations
were found in the old industrial district, suggesting it to be the principal emission source. The most important PCB homologue
group was tetra-PCB, followed by tri- and penta-PCB. The PCBs’ homologue composition differs from that found in Chinese transformer
oils: Chinese PCB products (no. 1 PCB and no. 2 PCB), Aroclor1242, and Aroclor1254. However, it is similar in composition
to that found in sediments and soils subjected to arbitrary disposal of used electronic appliances in this region. Our results
suggest that volatilization from PCB-contaminated soils in the old urban center may be the major source of PCBs in the atmosphere
of Guangzhou. Additional studies will be required to characterize the geochemical cycles of PCBs from the contaminated environmental
“hot spots” during the typical subtropical climate conditions in the study regions. 相似文献

This paper firstly presents an approach of parallel coordinates based parameter control panel (PCP). The PCP is used to control parameters of focal region-based volume rendering (FRVR) during data analysis. It uses a parallel coordinates style interface. Different rendering parameters represented with nodes on each axis, and renditions based on related parameters are connected using polylines to show dependencies between renditions and parameters. Based on the PCP, a concept of volume rendering guided search process is proposed. The search pipeline is divided into four phases. Different parameters of FRVR are recorded and modulated in the PCP during search phases. The concept shows that volume visualization could play the role of guiding a search process in the rendition space to help users to efficiently find local structures of interest. The usability of the proposed approach is evaluated to show its effectiveness. 相似文献

A matrix solid phase dispersion method was developed to detect eight pyrethroid insecticides in the aquatic invertebrate,
Chironomus dilutus. A mixture of silica gel, diatomaceous earth and primary/secondary amino solid absorbents were selected as the dispersion
matrix, while 7% ethyl ether in hexane was used as the elution solvent. Method detection limits for the target pyrethroids
ranged from 0.46 to 4.4 μg kg−1, and recoveries were 63.5%–124.0%, 43.7%–116.0% and 53.1%–93.1% at spiked levels of 5, 20 and 50 μg kg−1, respectively. The developed method was used to assess pyrethroid residues in laboratory-exposed and field-collected C. dilutus. 相似文献
