Alignment of main fluxes of energy in a target plane is found in families of cosmic ray particles detected in deep lead X-ray emulsion chambers. The fraction of aligned events becomes unexpectedly large for superfamilies with the total energy of gamma-quanta exceeding 10 TeV. This can be considered as an evidence of existence of coplanar scattering of secondary particles in interactions of prim...

In this perspectives article, we reflect upon the existence of chirality in atmospheric aerosol particles. We then show that organic particles collected at a field site in the central Amazon Basin under pristine background conditions during the wet and dry seasons consist of chiral secondary organic material. We show how the chiral response from the aerosol particles can be imaged directly with...

 Primary cosmic rays consist of various protons and atomic nuclei capable of penetrating the atmosphere  Bombarding with atmospheric nuclei yields secondary particles which continuously collide, resulting in the proliferation of more nucleons  These particles consist mainly of protons, neutrons and pions belonging to three distinct groups  Bruno Rossi, in 1929, performed an experiment using...

utilizing polymeric materials for damping mechanical waves is of great importance in various fields of applications such as military camouflage, prevention of structural vibrational energy transfer, and noise attenuation. this ability originates from segmental dynamics of chain-like polymer molecules. damping properties of styrene-butadiene rubbercontaining 10 wt% of monosize polystyrene partic...

It is of urgent need to identify the exact physico-chemical characteristics which allow maximum uptake and accumulation in secondary target organs of nanoparticulate drug delivery systems after oral ingestion. We administered radiolabelled gold nanoparticles in different sizes (1.4-200 nm) with negative surface charge and 2.8 nm nanoparticles with opposite surface charges by intra-oesophageal i...

The effect of chemical composition and the hot rolling operations on the microstructure and mechanical properties of in situ aluminum matrix composite with Mg2Si phase as the reinforcement was studied. It was revealed that the modification by phosphorous results in the rounder (more spherical) primary and secondary (eutectic) magnesium silicide intermetallics. During hot rolling, the primary pa...

a r t i c l e i n f o a b s t r a c t A computer program called Neutron_CR-39.F90 for neutron simulation through a PADC detector and its detection was described and developed. In this work the neutron Am–Be source was considered for simulation. It was shown that the most intensive secondary particles, created in neutron interactions with the detector, are protons. The programming steps are outl...
