Modification of polypropylene fibres by preirradiation technique

This work is dealing with grafting of poly-propylene fibres /POP/ prepared by the pre-irradiation technique. A hydrophility change in irradited and modified samples was studied. Irradiation was performed in a chamber type RCH-gamma-30 radiation equipment, containing⁶⁰Co. In the radiation modified samples of POP fibres prepared by the preirradiation technique the humidity adsorption increased from 0.1% to 0.56% after the radiation dose of 24.5 kGy has been used. The sorption properties of the samples were studied on McBeen balances with regard to temperature and water-vapour pressure.     

Improved synthesis of arachno-6,9-C2B8H14 and its halogenation under electrophilic conditions

A convenient synthesis of arachno-6,9-C₂B₈H₁₄, based on the reduction of nido-5,6-C₂B₈H₁₂ with sodium tetrahydroborate, is reported. Electrophilic halogenation of the former carborane produced a series of 1-X-6,9-C₂B₈H₁₃ (X = Cl, Br and I) derivatives whose constitution was established on the basis of their ¹H and ¹¹B NMR spectra.

Multiplicity distribution in antiproton-proton interactions

In a compilation of $\text{p}\text{p}$ interactions we present evidence for KNO scaling in the primary momentum region up to 7 GeV/c. The average multiplicity in $\text{p}\text{p}$ interactions and annihilations has a logarithmic increase with energy. The reduced statistical momenta of multiplicity distribution $\text{c}{}_{\mathrm{q}}\text{=}\text{〈n}{}^{\mathrm{q}}\text{〉}\text{〈n〉}{}^{\mathrm{q}}$ are energy independent and for all final states have practically the same values as in proton-proton interactions. In annihilations the c_q to appear to be different from those in pp interactions and the KNO scaling function is also different.
