In this paper, the EPICS2017 photoatomic database was used to evaluate photon mass attenuation coefficients and buildup factors of soils collected at different depths in Philippine islands. The extraction interpolation library accomplished recommended linear-linear scales obtain incoherent total cross section coefficient. were evaluated using G-P fitting method ANSI/ANS-6.4.3. An agreement achieved between XCOM, MCNP5, for calculated coefficient values. reported several penetration within...
The mass attenuation coefficient (MAC), effective atomic number (Zeff), and electron density (Neff) values of soils in mangrove forests across the Philippine islands were investigated. In addition, ENDF/B-VI.8 cross-section data library was used for interpolating Zeff Neff values. Photon energies considered this study ranged from 59.5–1332 keV. MAC obtained using MCNP5 PHITS Monte Carlo (MC) simulations found to be good agreement with XCOM literature. Results Phy-X/ZeXTRa program. Each...
Abstract Mass attenuation coefficients, effective atomic numbers, electron densities and energy absorption exposure buildup factors for the non-essential conditionally amino acids including alanine, arginine, asparagine, aspartic acid, cysteine, glutamic glutamine, glycine, proline, serine, tyrosine have been acquired using latest evaluated photoatomic library of EPICS2017. The was used by constructing an interpolation script that calculates all photon parameters. Comparisons were made...
A putative nucleopolyhedrovirus (NPV) from a field-collected local Spodoptera picta population was isolated for the first time. Its pathogenesis described in S. larvae and tentatively assigned name or SppiNPV. With objective of utilizing this SppiNPV as biological control agent, its cross-infectivity to litura – very important agricultural pest country evaluated. Third instar were infected with approximately 100 occlusion bodies (OBs) using artificial diet- incorporation. infection clearly...
The mechanical and radiation shielding properties for the PbO–MoO3–Li2O–B2O3 glass system were theoretically investigated in this paper. (coded as glasses) was fabricated using melt quenching mechanism. optical packing density (OPD) increases from 75.563 to 84.366, oxygen molar volume (OMV) decreases 13.234 11.853 cm3/mol when increasing PbO concentration. values of elastic moduli decreased 47.06 39.67 GPa Young, 33.51 32.41 bulk, 19.82 16.29 shear 59.94 54.14 longitudinal is increased....
Aedes aegypti strain obtained from field collections in Old Balara, Quezon City, Philippines was colonized at the Department of Science and Technology–Philippine Nuclear Research Institute (DOST-PNRI) laboratory. The number eggs their weight followed a significant linear relationship for Ae. colony. Storing hatching solution composed nutrient broth (NB) brewer’s yeast (BY) longer least 16 h hatched mosquito fastest within 4h. Among different ages tested, 2-wk-old had highest hatch rate....
