A large database of invasive forest pathogens (IFPs) was developed to investigate the patterns and determinants of invasion in Europe. Detailed taxonomic and biological information on the invasive species was combined with country-specific data on land use, climate, and the time since invasion to identify the determinants of invasiveness, and to differentiate the class of environments which sha...
Using the PIT method, multifilament wire with different packing strategies has been manufactured. In all, three types of wire have been investigated, a 19-filament configuration using ex-situ powder in an Fe-matrix and two 8-filament configurations in an Fe-matrix applying a copper core, one using in-situ and another using ex-situ powder. The effect on the annealing requirements during mechanic...
Prediction of in situ stresses, mud window and overpressure zone using well logs in South Pars field
This paper presents a novel hybrid in situ additive manufacturing (AM) method–laser shock forging (LSF), which combines laser peening (LSP) with melting deposition (LMD). Based on the classical bar-frame model and inherent strain theory, mechanisms of effects pretreatment posttreatment AM process have been elaborated for first time. Towards controlling tensile residual stress (TRS) as-built (AB...
For the design of steel-lined pressure tunnels and shafts in anisotropic rock, it is common practice to assume for the computation that the system stands in isotropic medium with the lowest stiffness measured in situ. In this paper, stresses and displacements in the steel liner of a particular steel-lined pressure tunnel are numerically assessed taking into account the anisotropic behavior of t...
This study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, Rubia tinctorum L. and alfalfa Medicago sativa. using in vitro and in situ measurements. The mean values for OM, CP, NDF, ADF and EE were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg DM for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg DM for alfalfa hay, respectiv...
Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...
