The design of all spatial scares in a manufactured environment is part of the architectural skills and knowtedge. Therefore, an architectural design should be drafted to reduce the vulnerability of humans and buildings against unexpected events, such as terrorist attacks and bombardments. Human casualties and equipment destruction inside the buitdings coutd be prevented by designing a suitabte architectural space. This study addresses the absence of a codified and detaited criterion to evatuate architecturat spaces and their design. Hence, art proposed indices for architectural spaces have been extracted using the ideas of experts in the field of architecture and exptosives. Questionnaires were presented to 25 experts to weigh the effective indices using the anatytic hierarchy process method. The human-oriented （ergonomic） characteristics of the buitding space is found to be the most important factor in facilitating crisis management, followed by the Location of criticat spaces.

Co纳米粒子催化无溶剂条件下一锅四组分法高效合成1,4-二氢吡啶衍生物(英文)

A straightforward and general method has been developed for the synthesis of C5-unsubstitiuted 1,4-dihydropyridines by a reaction using dimedone, acetophenone, aromatic aldehydes, and ammonium acetate in the presence of a catalytic amount of Co nanoparticles as a heterogeneous and eco-friendly catalyst with high catalytic activity at room temperature under solvent-free conditions. This catalyst is easily separated by magnetic devices and can be reused without any apparent loss of activity for the reaction. In addition, it is very interesting that when using Co nanoparticles as a catalyst, spatially-hindered aldehydes such as 2-methoxy-, 2-fluoro-, and 2-chloro-aldehydes are suitable for this reaction.

Enrichment of <i>Artemia</i>(Leach) nauplii with Canola Oil: Effect on <i>Heros severus</i>(Heckel) Larvae Performance and Environmental Stress

The effect of canola oil enriched Artemia (Leach) nauplii on growth, survival, resistance to environmental stresses of temperature and oxygen deficiency and fatty acid composition in severum fish, Heros severus (Heckel), larvae were investigated. The larvae (average weight 3 mg ± 0.83) were fed 4 times daily starting at the onset of exogenous feeding for 18 days. Triplicate groups of fish were offered one of two treatments: 1) newly hatched Artemia (Leach) nauplii (unenriched) and 2) canola oil enriched Artemia (Leach) nauplii. Then all groups of fish were switched to the commercial diet for an additional period of 18 days. Statistical analysis of growth after 18 days and at the end of the experiment (36 days), showed that the highest specific growth rates (9.65% ± 0.3), (17.44% ± 0.31) the average weight (17 mg ± 0.95), (65.2 mg ± 0.53) were observed in treatment 2 respectively, but there was no significant difference in survival rate between treatments. The best result of resistance to oxygen deficiency (5 min) was observed in larvae reared on treatment 2 with 75.67% ± 0.66 after 36 days. Result of temperature stress showed no significant difference between treatments. The larvae were also found to convert n-3 fatty acids to EPA and DHA.
