In this paper, we aim to compare the investigations of Blood found on Shroud Turin and Saint Januarius. Analysis first relic reveals presence whole blood with bile pigments. fact, fibrils covered in serum albumin were also extracted from burial linen. For latter relic, situation remains uncertain, as Roman Catholic Church does not allow sampling. This is puzzling, given that Jesus, which present Shroud, has already been investigated. Why should it be possible investigate Januarius? Only...
A new approach to the production and detection of bound neutron clusters is presented. The technique based on breakup beams very neutron-rich nuclei subsequent recoiling proton in a liquid scintillator. method has been tested 11Li, 14Be 15B by C target. Some 6 events were observed that exhibit characteristics multineutron cluster liberated 14Be, most probably channel 10Be+4n. various backgrounds may mimic such signal are discussed detail.
The two-neutron halo nucleus ${}^{14}\mathrm{Be}$ has been investigated in a kinematically complete measurement of the fragments ( ${}^{12}\mathrm{Be}$ and neutrons) produced dissociation at 35 MeV/nucleon on C Pb targets. Two-neutron removal cross sections, neutron angular distributions, invariant mass spectra were measured, contributions from electromagnetic (EMD) deduced. Comparison with three-body model calculations suggests that wave function contains large...
Three-body correlations in the dissociation of two-neutron halo nuclei are explored using a technique based on intensity interferometry and Dalitz plots. This provides for combined treatment both n-n core-n interactions exit channel. As an example, breakup 14Be into 12Be+n+n by Pb C targets has been analysed separation extracted. A finite delay between emission neutrons reaction target was observed is attributed to 13Be resonances populated sequential breakup.
The dynamical effects of the entrance channel on formation evaporation residues are studied by analyzing $^{40}\mathrm{Ar}+^{176}\mathrm{Hf}$, $^{86}\mathrm{Kr}+^{130,136}\mathrm{Xe}$, $^{124}\mathrm{Sn}+^{92}\mathrm{Zr}$, and $^{48}\mathrm{Ca}+^{174}\mathrm{Yb}$ reactions leading to $^{216}\mathrm{Th}{}^{*}$ $^{222}\mathrm{Th}{}^{*}$ compound nuclei. We find that difference between residue cross sections for same nucleus is caused different angular momentum distributions partial fusion...
Background: Isolated left ventricular non‐compaction is the result of incomplete myocardial morphogenesis, leading to persistence embryonic myocardium. The condition recognized by an excessively prominent trabecular meshwork and deep intertrabecular recesses ventricle. Whether these are a favorable substrate for arrhythmias unclear. Some reports have found that fatal may occur in approximately half patients. In this report we investigated about association. Methods Results: total evaluated...
Noncompaction of left ventricular myocardium is a rare congenital cardiomyopathy resulting from an incomplete myocardial morphogenesis that leads to the persistence embryonic myocardium. This condition characterized by thin compacted epicardial and extremely thickened endocardial layer with prominent trabeculations deep intertrabecular recesses. It not clear, in noncompaction myocardium, whether recesses could be responsible for thrombi formation thromboembolic complications.The prevalence...
The experimental data on the capture and evaporation residue cross-sections obtained in 48 Ca + 208 Pb reaction were analyzed framework of dynamical model based dinuclear system concept advanced statistical method to clarify mechanism. excitation function reactions was decomposed into contributions fusion–fission, quasifission fast-fission processes. Total residues ones after neutron emission only calculated compared with available data.
The influence of the orientation angles target nucleus symmetry axis, relative to beam direction, on production evaporation residues is investigated for 48 Ca+ 154 Sm reaction as a function energy. At low energies ( E c.m. <137 MeV), yield observed only collisions with small (α T <45°). large (about =140–180 all α can contribute residue cross section σ ER in 10–100 mb range. >180 MeV, ranges approximately 0.1–10 because fission barrier compound decreases increasing excitation energy and...
The study of the bremsstrahlung photon emission accompanying fragments produced in spontaneous fission heavy nuclei by a fully quantum approach is presented for first time. This kind problem requires knowledge wave functions fissioning system leading to wide distribution couples that are products fission. With aim obtaining these functions, interaction potential between emitted fragment and residual nucleus calculated standard approach. A new procedure was performed allows an increase...
The excitation functions of capture, complete fusion, and evaporation residue formation in the $^{16}$O+$^{184}$W $^{19}$F+$^{181}$Ta reactions leading to same $^{200}$Pb compound nucleus has been studied theoretically explain experimental data showing more intense yield former reaction comparison with that latter reaction. observed difference is explained by large capture cross section increase quasifission contribution fission-like fragments at energies. probability larger but nuclei...

The radiative hypothesis has been revisited showing other characteristics, produced by the protons used as dyes in total disagree with ones of Body Image that appears on Shroud Turin. Our investigations highlight for to reach 3.7 cm air, distance measures range discoloration effects, must be emitted an energy about 1.5 MeV using Wilson and Brobeck’s empirical formula 1.35 Bethe’s. This last provides a result closer reality. Bethe shows penetration depth is greater than calculated...
