The test basis is provided for the development of high performance concrete of metakaolin through studying the performance of metakaolin in high performance concrete, which is to meet the demand of high performance concrete in modern industry.The experiment shows that the incorporation of metakaolin has a great influence on the strength of concrete
A study was conducted to standardize packaging technology for export of jasmine flowers.Experiments were laid out in FCRD in three replications, with 12 chemical treatments, and packing with unit packing boxes and thermocol boxes under gel-ice cold condition.Effects of various chemical treatments and their Teaching Posters interaction with packagin
Densified wood technology improves the wood properties such as strength, surface hardness, dimensional stability, and durability.However, the utilization of laminated veneer as densified wood which is used as an armor material, and its ability to absorb ballistic energy has not been researched.The strengthening of the Teak Platinum veneer, which wa
Many optimization problems have become increasingly complex, which promotes researches on the improvement of different optimization algorithms.The monarch butterfly optimization (MBO) algorithm has proven to be an effective tool to solve various kinds of optimization problems.However, in the basic MBO algorithm, the search strategy easily falls int
The asilid genus Laphyctis Loew, 1858 is revised.The genus is restricted to the Grill Pans Afrotropical Region where it has been confused with the more widely distributed Laphystia Loew, 1847, which currently has no Afrotropical representatives.Three previously described species are recognised: Laphyctis gigantella (Loew, 1852), type of the genus,
