UDK 630*52(497.6) Prva inventura šuma na velikim površinama u BiH je provedena prije 40 godina, u periodu od 1964. do 1968. Druga državna inventura šuma je započela u 2006. godini, sa planom da se završi krajem 2009. godine. Šumskogospodarska oblast „Unska” na sjeverozapadu BiH je premjerena u 2006. godini, u prvoj fazi inventure šuma. Ovaj rad sadrži skraćeno pojašnjenje inventurnih koncepata i podatke o glavnim taksacionim elementima za oblast Unsku, po glavnim kategorijama šuma i šumskih zemljišta, površina, zaliha i zapreminski prirast iz dvije državne inveture šuma koji su poređeni i prezentirani u ovom radu. Razlike u prikazanim podacima su značajne. Možemo sa sigurnošću reći da su se desile velike promjene tokom 40- godišnjeg perioda, u ukupnoj površini šuma i u stukturi površina po glavnim kategorijama šuma. Površine šuma su se povećale za oko 35%, za više od 60 000 ha. Zaliha je takođe povećana sa 125,8 m3/ha na 248 m3/ha ili ukupno za više od 40 350 000 m3 sveukupne drvne mase. Površine šuma su procijenjene na tri različita i neovisna načina. U drugoj inventuri površine šuma su mjerene interpretacijom satelitskih snimaka i na osnovu terenskih snimanja kroz broj ploha. Treći način se odnosi na sumiranje podataka iz važećih šumskogospodarskih osnova ovog područja. Razlike između podataka o površinama utvrđenih na tri različita načina nisu statističi značajne. Možemo zaključiti da je ovo važno pitanje utvrđivanja površina šuma i šumskih zemljišta riješeno na kvalitetan način i kroz terenska snimanja u ovoj oblasti i, s obzirom na to, pretpostavljamo da će biti kvalitetno urađeno i za cijelu BiH.

The problem of motion planning and control of mobile robots has attracted the interest of researchers in view of its theoretical challenges because of their obvious relevance in applications. From a control viewpoint, the peculiar nature of nonholonomic kinematics and dynamic complexity of the mobile robot makes that feedback stabilization at a given posture cannot be achieved via smooth time-invariant control (Oriolo et al., 2002). This indicates that the problem is truly nonlinear; linear control is ineffective, and innovative design techniques are needed. In recent years, a lot of interest has been devoted to the stabilization and tracking of mobile robots. In the field of mobile robotics, it is an accepted practice to work with dynamical models to obtain stable motion control laws for trajectory following or goal reaching (Fierro & Lewis, 1997). In the case of control of a dynamic model of mobile robots authors usually used linear and angular velocities of the robot (Fierro & Lewis, 1997; Fukao et al., 2000) or torques (Rajagopalan & Barakat , 1997; Topalov et al., 1998) as an input control vector. The central problem in this paper is reduction of control torques during the reference position tracking. In the case of dynamic mobile robot model, the position control law ought to be nonlinear in order to ensure the stability of the error that is its convergence to zero (Oriollo et al., 2002). The most authors solved the problem of mobile robot stability using nonlinear backstepping algorithm (Tanner & Kyriakopoulos, 2003) with constant parameters (Fierro & Lewis, 1997), or with the known functions (Oriollo et al., 2002). In (Tanner & Kyriakopoulos, 2003) a combined kinematic/torque controller law is developed using backstepping algorithm and stability is guaranteed by Lyapunov theory. In (Oriollo et al., 2002) method for solving trajectory tracking as well as posture stabilization problems, based on the unifying framework of dynamic feedback linearization was presented. The objective of this chapter is to present advanced nonlinear control methods for solving trajectory tracking as well as convergence of stability conditions. For these purposes we developed a backstepping (Velagic et al., 2006) and fuzzy logic position controllers (Lacevic, et al., 2007). It is important to note that optimal parameters of both controllers are adjusted using genetic algorithms. The novelty of this evolutionary approach lies in automatic obtaining of suboptimal set of control parameters which differs from standard manual adjustment presented in (Hu & Yang, 2001; Oriolo et al., 2002). The considered motion control system of the mobile robot has two levels. The lower level subsystem deals with the

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.

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.

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.

CONFLICT OF INTEREST: NONE DECLARED Distance learning refers to use of technologies based on health care delivered on distance and covers areas such as electronic health, tele-health (e-health), telematics, telemedicine, tele-education, etc. For the need of e-health, telemedicine, tele-education and distance learning there are various technologies and communication systems from standard telephone lines to the system of transmission digitalized signals with modem, optical fiber, satellite links, wireless technologies, etc. Tele-education represents health education on distance, using Information Communication Technologies (ICT), as well as continuous education of a health system beneficiaries and use of electronic libraries, data bases or electronic data with data bases of knowledge. Distance learning (E-learning) as a part of tele-education has gained popularity in the past decade; however, its use is highly variable among medical schools and appears to be more common in basic medical science courses than in clinical education. Distance learning does not preclude traditional learning processes; frequently it is used in conjunction with in-person classroom or professional training procedures and practices. Tele-education has mostly been used in biomedical education as a blended learning method, which combines tele-education technology with traditional instructor-led training, where, for example, a lecture or demonstration is supplemented by an online tutorial. Distance learning is used for self-education, tests, services and for examinations in medicine i.e. in terms of self-education and individual examination services. The possibility of working in the exercise mode with image files and questions is an attractive way of self education. Automated tracking and reporting of learners’ activities lessen faculty administrative burden. Moreover, e-learning can be designed to include outcomes assessment to determine whether learning has occurred. This review article evaluates the current status and level of tele-education development in Bosnia and Herzegovina outlining its components, faculty development needs for implementation and the possibility of its integration as official learning standard in biomedical curricula in Bosnia and Herzegovina. Tele-education refers to the use of information and communication technologies (ICT) to enhance knowledge and performance. Tele-education in biomedical education is widely accepted in the medical education community where it is mostly integrated into biomedical curricula forming part of a blended learning strategy. There are many biomedical digital repositories of e-learning materials worldwide, some peer reviewed, where instructors or developers can submit materials for widespread use. First pilot project with the aim to introduce tele-education in biomedical curricula in Bosnia and Herzegovina was initiated by Department for Medical Informatics at Medical Faculty in Sarajevo in 2002 and has been developing since. Faculty member’s skills in creating tele-education differ from those needed for traditional teaching and faculty rewards must recognize this difference and reward the effort. Tele-education and use of computers will have an impact of future medical practice in a life long learning. Bologna process, which started last years in European countries, provide us to promote and introduce modern educational methods of education at biomedical faculties in Bosnia and Herzegovina. Cathedra of Medical informatics and Cathedra of Family medicine at Medical Faculty of University of Sarajevo started to use Web based education as common way of teaching of medical students. Satisfaction with this method of education within the students is good, but not yet suitable for most of medical disciplines at biomedical faculties in Bosnia and Herzegovina.
