The question to choose a grain supplement emergency path is uncertain. By using uncertain methods, integration of experts can be done. Base on the uncertain theory, we build the model of choosing a path with minimum risk in the process of grain emergency transportation and the algorithm. Firstly, estimate every path in the net to get the unascertained numbers of experts. Then, the unascertained number of experts with the uncertain operate rule is computed. Thirdly, the expectation and reliability of its unascertained number can be gotten. At last, get the minimum risk path by operate the expectation and the experiential value. This model has certain rationality and validity by data test.

Entropy Weight Method

Emergency events are full of large number of uncertain information. The existence of these uncertain information leads to less research on emergency logistics involving transshipment scenarios. In this paper, a new emergency transport model is proposed, which simulates the scenario of emergency transport from the logistics center to each disaster site and between each disaster site. The single-valued neutrosophic set (SVNS) is applied to transform the emergency transshipment problem into a multiattribute decision-making problem in ambiguous and uncertain environments. Technology for order preference by similarity to ideal solution (TOPSIS) is extended to the single-valued neutrosophic environment to rank and optimize the alternative transshipment routes. Firstly, the attribute weight is determined by using the entropy weight method; secondly, the scoring function of the single-valued neutrosophic fuzzy number is defined; thirdly, the TOPSIS method is used to rank the decision-making; finally, the feasibility and rationality of the proposed method are verified by an emergency operation example.

Opioid Detoxification

Materials and Methods. Published articles on the opioid abuse and methods of opioid detoxification were identified by searching medical databases, using corresponding literature and were also searched manually for applicable papers. The search was limited to articles published from 1985 through 2014. Results. Opioid dependence determine pathophysiologic changes in the dopaminergic pathways of the organism, as well as the alterations in the stress-responsive hypothalamic-pituitary-adrenal axis. The usage of opioid antagonists in the early stages of withdrawal, can lead the effectiveness of opioid detoxification to 100%. Rapid opioid detoxification do not remove all the symptoms of abstinence. Negative aspects, concerning the procedure, while using prevention, can be reduced to the minimum risk. Rapid opioid detoxification, comparing it with Ultrarapid opioid detoxification procedure, diverges as less financial resources and a lower risk containing technique. Conclusions. Use of antagonists may reduce the duration of withdrawal, thus reducing the overall severity of withdrawal and increasing the chances of successful completion. This technique facilitates commencement of naltrexone treatment. Dosing regimens used in clinical trials vary. Subsequent results do not correlate with the methods of detoxification.

Iodinated Contrast

Iodine containing contrast media are used much frequently now-a-days for computed tomography examinations in children. The group of non-ionic monomers occupies a special place among modern contrast agents. Low osmolarity and viscosity, electrical neutrality and the highest iodine content of these contrast materials provide the best diagnostic efficacy with minimum risk of adverse reactions. However, characteristic anatomic and physiological aspects of a growing child’s body require additional attention and care during diagnostic procedures with use of such contrast agents. This article presents concise literature review of recent years highlighting practical aspects of nonionic lowosmolar iodinated contrast material use for computed tomography assisted diagnostic examinations in child population.

Organic Carbon Concentration

Thorium-234 (234Th) is a powerful tracer of particle dynamics and the biological pump in the surface ocean; however, variability in carbon:thorium ratios of sinking particles adds substantial uncertainty to estimates of organic carbon export. We coupled a mechanistic thorium sorption and desorption model to a one-dimensional particle sinking model that uses realistic particle settling velocity spectra. The model generates estimates of 238U-234Th disequilibrium, particulate organic carbon concentration, and the C:234Th ratio of sinking particles, which are then compared to in situ measurements from quasi-Lagrangian studies conducted on six cruises in the California Current Ecosystem. Broad patterns observed in in situ measurements, including decreasing C:234Th ratios with depth and a strong correlation between sinking C:234Th and the ratio of vertically-integrated particulate organic carbon (POC) to vertically-integrated total water column 234Th, were accurately recovered by models assuming either a power law distribution of sinking speeds or a double log normal distribution of sinking speeds. Simulations suggested that the observed decrease in C:234Th with depth may be driven by preferential remineralization of carbon by particle-attached microbes. However, an alternate model structure featuring complete consumption and/or disaggregation of particles by mesozooplankton (e.g. no preferential remineralization of carbon) was also able to simulate decreasing C:234Th with depth (although the decrease was weaker), driven by 234Th adsorption onto slowly sinking particles. Model results also suggest that during bloom decays C:234Th ratios of sinking particles should be higher than expected (based on contemporaneous water column POC), because high settling velocities minimize carbon remineralization during sinking.
