sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. this paper initiates and presents a new type of central core honeycomb formed by hydroforming process. the study is augmented by ...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

the core sediment samples were analysed for grain size, carbonates (caco3), organic carbon (oc) to obtain a preliminary view of its environmental conditions near point calimere along the southeast coast of vedaranyam, india.the high concentration of sand in the core is attributed to the tidal influence at the akkarapallivasal river mouth. the sea water which enters the river suspends the floccu...

In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...

qualitative analysis of petroleum reservoir rocks is still one of the most important topics of core laboratories and directly affects hydrocarbon-in-place, fluid flow, and prediction of field performance. magnetic resonance imaging (mri) as a non-invasive, millimeter resolution technique which only images fluids in porous media fits this purpose perfectly. magnetic resonance is a radio frequenc...
