Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

The air transport industry is seeking to manage risks in air travels. Its main objective is to detect abnormal behaviors in various flight conditions. The current methods have some limitations and are based on studying the risks and measuring the effective parameters. These parameters do not remove the dependency of a flight process on the time and human decisions. In this paper, we used an HMM...

On 5 May 1902, Spanish engineer Leonardo Torres Quevedo applied for a Patent in France for “Improvements in dirigible aerostats”, complemented, with a “Note on the calculus of a dirigible balloon with interior suspension and keel” presented together to Madrid and Paris’ Academies of Science. He had conceived a complex inner structure, all along the envelope of the aerostat: a longitudinal frame...

one of the most important measures, in order to increase animal products and reduce imports, is the industrialization of animal husbandry units, specially the dairy cattle. the condition of milk production would be improved by this industrialization, which is in the direction of increasing the efficiency of milk production units. the purpose of this study is calculate , the efficiency of the tr...

Vertical flight performance of Lighter-than-Air free hot-air balloons is derived and discussed. Novel mathematical model using lumped-parameters has been used to balloon dynamics steady-state in particular. Thermal was not treated as the super-heat under control aeronauts/pilots. Buoyancy or gross lift, net effective specific excess lift were for a general single envelope can be applied hot-air...

birds, sometimes numbering in millions, can cause serious damage to grain fields. in order to find a method to accordance with environmental issues and effective in controlling these birds, in this research, the effect of sound was studied for keep birds away. the broadcast unit was developed with the following design criteria: 1) three sound levels of hawk, gas gun and sparrow distress, with f...
