Some thermodynamic and explosive properties of the recently reported 1-azido-2-nitro-2-azapropane (ANAP) have been determined in a combined computational ab initio (MP2/aug-cc-pVDZ) and EXPLO5 (Becker–Kistiakowsky–Wilson's equation of state, BKW EOS) study. The enthalpy of formation of ANAP in the liquid phase was calculated to be ΔfH°, ANAP(l)=+297.1 kJ mol−1. The heat of detonation (Qv), the detonation pressure (P), and the detonation velocity of ANAP were calculated to be Qv=−6088 kJ kg−1, P=23.8 GPa, D=8033 m s−1. A mixture of ANAP and tetranitromethane (TNM) was investigated in an attempt to tailor the impact sensitivity of ANAP, but results obtained indicate that the mixture is almost as sensitive as pure ANAP. On the other hand, ANAP and TNM were found to be chemically compatible (1H, 13C, 14N NMR; DSC) and a 1 : 1 mixture (by weight) of both components was calculated to have superior explosive properties than either of the individual components: Qv=−6848 kJ kg−1, P=27.0 GPa, D=8284 m s−1.

UDK 630*33:620.91(497.6) Šume i šumska zemljišta sa učešćem od preko 50 % u ukupnoj površini BiH predstavljaju veliki izvor obnovljivih vidova energije, posebno drvne biomase. Ekološke, sociološke i ekonomske pogodnosti upotrebe ovog energenta snažan su argument u prilog istraživanju mogućnosti njegovog većeg korištenja. U ovom radu izvršena je procjena energetskog potencijala drvne biomase u BiH kao neophodne polazne osnove za buduće naučno-istraživačke aktivnosti na ovom polju. Rezultati rada pokazuju da BiH, srazmjerno svojoj površini, ima prilično veliki energetski potencijal u drvnoj biomasi u iznosu od 2,9 mil. t/god. Mogućnost njenog efikasnijeg korištenja ovisi prije svega od zainteresovanosti i spremnosti nadležnih institucija da na odgovarajući način educiraju potencijalne potrošače o svim pogodnostima i prednostima koje njena upotreba pruža, ali i da ih na adekvatan način finansijski stimuliše.

SUMMARY: We reconsider the basic properties of the classical minihalo model of Rees and Milgrom in light of the new work, both observational (on "dark galaxies" and masses of baryonic haloes) and theoretical (on the cosmological mass function and the history of star formation). In particular, we show that more detailed models of ionized gas in haloes of dark matter following isothermal and NavarroFrenk-White density proflle can efiectively reproduce particular aspects of the observed column density distribution function in a heterogeneous sample of low- and intermediate-redshift Lyfi forest absorption lines.
