Particle induced nuclear reaction calculations of Boron target nuclei
(EDP SCIENCES., 2017)Boron is usable element in many areas such as health, industry and energy. Especially, Boron neutron capture therapy (BNCT) is one of the medical applications. Boron target is irradiated with low energy thermal neutrons ... -
Photoredox cross-coupling: Ir/NidDual catalysis for the synthesis of Benzylic Ethers
(AMER CHEMICAL SOC., 2015)Single-electron transmetalation has emerged as an enabling paradigm for the cross-coupling of C-sp(3) hybridized organotrifluoroborates. Cross-coupling of alpha-alkoxymethyl-trifluoroborates with aryl and heteroaryl bromides ... -
Pollen analyses and antimicrobial properties of the natural honey from the east mediterranean part of anatolia
(ZOOLOGICAL SOC PAKISTAN, 2019)The pollen analysis of eight floral honey samples from Kahramanmaras region were analyzed and seven samples were the unifloral and the one was the multifloral origin. The microscopical analyses indicated that 61 taxa (41 ... -
Polynomial affine translation surfaces in euclidean 3-Space
(SOC PARANAENSE MATEMATICA, 2019)In this paper we study the polynomial affine translation surfaces in E-3 with constant curvature. We derive some non-existence results for such surfaces. Several examples are also given by figures. -
Problems in detection and measurement in nuclear medicine
(EDP SCIENCES., 2015)Nuclear Medicine studies are performed with a variety of types of radiation measurement instruments, depending on the kind of radiation source that is being measured and the type of information sought. For example, some ... -

Semi-Empirical Formula with New Coefficients of the (alpha,n) Reaction Cross-Section
(POLISH ACAD SCIENCES INST PHYSICS, 2015)A new modified semi-empirical formula including non-elastic scattering and Coulomb effects for the (alpha,n) reaction cross-section was obtained. The available experimental data were used to get the (alpha,n) reaction ... -
Semigroup presentation for congruences on groups
(KOREAN MATHEMATICAL SOC, 2013)We consider a congruence rho on a group G as a subsemigroup of the direct product G x G. It is well known that a relation rho on G is a congruence if and only if there exists a normal subgroup N of G such that rho = {(s, ... -
Set similarity modulates object tracking in dynamic environments
(SPRINGER, 2018)Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers' abilities to track a ball target passed between 20 colored circle ... -
Short- and long-term forms of neural adaptation: An ERP investigation of dynamic motion aftereffects
(ELSEVIER MASSON,, 2020)Adaptation is essential to interact with a dynamic and changing environment, and can be observed on different timescales. Previous studies on a motion paradigm called dynamic motion aftereffect (dMAE) showed that neural ... -
