Fire Resistance of Concrete with Fly Ash Content – Experimental Analysis
The paper presents results from three large scale experiments on seven reinforced concrete panels obtained during an extensive experimental program. This was aimed at possible application of cement reduced (fly ash replaced) concrete in the production of precast segmental linings for tunnels created by a tunnel boring machine (TBM). In particular, this paper is focused on the comparison of fire...
متن کاملFight fire with fire
Since our hunter–gatherer ancestors began to develop agriculture more than 10,000 years ago, farmers have been battling with Nature to protect their cultivated plants against pests and diseases. Organisms from all kingdoms of life—from mammals and insects to bacteria, fungi and viruses—are attracted by the easy pickings that large fields of plants represent, and farmers have sought to contain t...
متن کاملInvadolysin opens many doors
Making a raft with oligomers pithelial cells differentially segregate proteins to their apical and basolateral surfaces. For some apical localization events, association of glycosylphosphatidylinositol (GPI)anchored proteins with detergent-resistant rafts is necessary but not sufficient. Now, on page 699, Paladino et al. show that the key for proper protein sorting may be the formation of high ...
متن کاملFire resistance of FRP reinforced glulam beams
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
متن کاملDoS: Fighting Fire with Fire
We consider DoS attacks on servers in which attackers’ requests are indistinguishable from legitimate requests. Most current defenses against this class of attack rely on legitimate users in aggregate having more of some resource (CPU cycles, memory cycles, human attention, etc.) than attackers. A server so defended asks prospective clients to prove their legitimacy by spending some of this res...
