Prediction of concrete penetration using Forrestals formula
(2000)The various existing empirical formulas for predicting penetration into concrete targets are seen to give different results. Explaining the difference is difficult since most of the original empirical data behind the ... -
Preliminary assessment of the vertical release of liquefied chlorine inside a depression
(2009)Toxic industrial chemicals (TICs) are used in most places and can pose a threat due to accidents, terror, or sabotage. Many of the most common TICs are gasses at ambient atmosphere, such as chlorine, ammonia, and sulfur ... -
Preliminary numerical simulation of the dispersion of chlorine vapour in a mock urban environment for the Jack Rabbit II field trials
(2016-02-02)The release and dispersion of toxic industrial chemicals as a result of accidents, terrorism, or sabotage represent a possible hazard for life and health. Such chemicals are often transported and stored as condensed ... -
Preparation and characterisation of epoxy/alumina polymer nanocomposites
(2013)The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ... -
Preparation of biological contaminated samples for chemical analysis
(2009)FFI has established laboratory facilities in order to receive and analyze samples containing a mixture of chemical, biological and radiological (CBR) agents, so-called “mixed samples”. Detailed procedures are needed to ... -

(2004)This report gives an overview and a discussion of the development and utilisation of long-range precision guided munitions in recent military operations – starting with Desert Storm in 1991. The open literature has been ... -
Prestasjonsbasert logistikk (PBL) - muligheter og utfordringer
(2011-11-01)Prestasjonsbasert logistikk, eller Performance-Based Logistics (PBL), er et relativt nytt konsept for understøttelse av militære systemer. En grunntanke i PBL er endringen fra den tradisjonelle transaksjonsbaserte formen ... -
Pretreatment and prophylaxis against nerve agent poisoning: are undesirable behavioral side effects unavoidable?
(2016)The threat of chemical warfare agents like nerve agents requires life saving measures of medical pretreatment combined with treatment after exposure. Pretreatment (pyridostigmine) may cause some side effects in a small ... -
Prinsipper for en bærekraftig forsvarsøkonomi
(2015-10-08)I denne rapporten diskuteres prinsipper for en bærekraftig forsvarsøkonomi. Prinsippene er allmenne og kan vektes ulikt avhengig av hvilken forsvarsstruktur de anvendes på. I rapporten defineres bærekraftig forsvarsøkonomi ... -

(2019-05-08)Forsvarets oppgave nummer 1 er å «Sikre troverdig avskrekking med basis i NATOs kollektive forsvar». I denne rapporten diskuterer vi hva som kan ligge i «troverdig avskrekking» ved å bruke operasjonsanalyse som verktøy. ... -
Pro-inflammatory cytokines in cystic glioblastoma: A quantitative study with a comparison with bacterial brain abscesses. With an MRI investigation of displacement and destruction of the brain tissue surrounding a glioblastoma
(2022-07-29)Cystic glioblastomas are aggressive primary brain tumors that may both destroy and displace the surrounding brain tissue as they grow. The mechanisms underlying these tumors’ destructive effect could include exposure of ... -
Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment
(2021-11-13)The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ... -
