RC Slabs Retrofitting Against Blast Loading by GFRP-PU and CFRP-PU

Plutonium isotopes 238 Pu , 239 + 240 Pu and 241 Pu in the Baltic Sea ecosystem

Wet and dry atmospheric fallout from nuclear weapon tests is one of the most important sources of plutonium in the Baltic Sea. The other sources: plutonium releases from spent fuel facilities in Sellafield (UK) and Cap de la Hague (France) are less important. Since 26 April 1986 it has been a new source of plutonium – Chernobyl plutonium, which should be taken under note in estimation of its ra...

Pu(V) and Pu(IV) sorption to montmorillonite.

Plutonium (Pu) adsorption to and desorption from mineral phases plays a key role in controlling the environmental mobility of Pu. Here we assess whether the adsorption behavior of Pu at concentrations used in typical laboratory studies (≥10(-10) [Pu] ≤ 10(-6) M) are representative of adsorption behavior at concentrations measured in natural subsurface waters (generally <10(-12) M). Pu(V) sorpti...

Strengthening of RC Slabs with Symmetric Openings Using GFRP Composite Beams

This paper describes the results of experimental testing of glass fiber reinforced plastic (GFRP) composite beam strengthened reinforced concrete (RC) slabs with two symmetrical openings. Specimens, one-half scale, have been designed and fabricated to reflect the most common RC bathroom slab used in school buildings. The specimen had dimensions of 2000 mm (width) × 150 mm (thickness) × 3000 mm ...

formed during the contact of sodium hypochlorite (NaOCl) with bovine pulp and dentin. For analysis of the products formed in the volatile phase, 11 mg of bovine pulp tissue were placed in contact with 0.5%, 2.5% and 5.25% NaOCl until complete tissue dissolution occurred. The solid phase microextraction (SPME) fiber was exposed inside the container through the cover membrane and immediately inje...

Non-Linear Finite Element Analysis of RC Slabs Strengthened with CFRP Laminates

The present study deals with the finite element modelling of control RC slabs and strengthened slabs with the help of ANSYS. ANSYS is software that is based on FE method in which modelling of RC structures is done. In this study, a control slab was modelled and the results were analysed and then strengthened slabs were modelled and analysed. The results of the control and strengthened slabs wer...
