General Äadās warfare and the departure of the 13th JNA Corps from Croatia
Za poznavanje zbivanja u Domovinskom ratu na podruÄjima zapadne Hrvatske
nezaobilazna je prosudba zapovijedanja i postupaka komandanta 13. rijeÄkog
korpusa JNA general-potpukovnika Marijana Äada. General je sve do potpisivanja sporazuma s predstavnicima hrvatske vlasti u studenom 1991. dosljedno
izvrÅ”avao povjerene mu zadatke od strane nadreÄenih mu zapovjedniÅ”tava JNA.
ZapovijedajuÄi postrojbama na podruÄju Like i Gorskog kotara upravljao je borbenim djelovanjima postrojbi JNA i pobunjenih Srba, u okviru napadne operacije
na Republiku Hrvatsku u jesen 1991. godine. IzvlaÄenjem postrojbi 13. korpusa
s rijeÄkog podruÄja general Äad je ispunio svoj ratni zadatak te povrh svega oÄuvao svoja graÄanska prava u Republici Hrvatskoj. U javnom mnijenju je za mnoge ostao spasitelj grada Rijeke od ratnih razaranja. RazmatrajuÄi slijed dogaÄaja
i pojedine manje poznate Äinjenice, u tekstu se nastojalo dati cjelovitu sliku i utemeljenu ocjenu njegove uloge, i odgovornosti u ratnim sukobima do potpisivanja
sporazuma o odlasku 13. korpusa iz Hrvatske.In order to be familiar with events in the Homeland War on the territory of western Croatia it is obligatory to assess the command and actions of the commandant of the 13th Rijeka Corps of the Yugoslav Peopleās Army (JNA), the Lieutenant
General Marijan Äad. Up until the signature of the agreement with the representatives of the Croatian Government in November 1991 the General consistently
carried out tasks entrusted to him by the JNA commands that were his superior.
Commanding the troops in the territory of Lika and Gorski kotar he directed the
armed combat of the JNA and the rebelled Serbs troops within the attack operation at the Republic of Croatia in the autumn of 1991. By getting the troops of
the 13th Corps out of the area of Rijeka General Äad fulfilled his war mission and
most of all he kept his civil rights in the Republic of Croatia. He remained for the
many in the public opinion the saviour of the city of Rijeka from the destruction
of war. By considering the sequence of events and some lesser known facts the paper endeavours to give the complete picture and the based assessment of his role
and responsibility in war conflicts until the signature of the agreement regarding
the 13th Corps departing from Croatia
Partial rip scenarioāa cosmology with a growing cosmologicalĀ term
AbstractA cosmology with the growing cosmological term is considered. If there is no exchange of energy between vacuum and matter components, the requirement of general covariance implies the time dependence of the gravitational constant G. Irrespectively of the exact functional form of the cosmological term growth, the universe ends in a de Sitter regime with a constant asymptoticĀ Ī, but vanishing G. Although there is no divergence of the scale factor in finite time, such as in the āBig Ripā scenario, gravitationally bound systems eventually become unbound. In the case of systems bound by non-gravitational forces, there is no unbounding effect, as the asymptotic Ī is insufficiently large to disturb these systems
Dark energy transition between quintessence and phantom regimes - an equation of state analysis
The dark energy transition between quintessence () and phantom ()
regimes (the crossing of the cosmological constant boundary) is studied using
the dark energy equation of state. Models characterized by this type of
transition are explicitly constructed and their equation of state is found to
be {\em implicitly} defined. The behavior of the more general models with the
implicitly defined equation of state, obtained by the generalization of the
explicitly constructed models, is studied to gain insight into the necessary
conditions for the occurrence of the transition, as well as to investigate the
mechanism behind the transition. It is found that the parameters of the
generalized models need to satisfy special conditions for the transition to
happen and that the mechanism behind the transition is the cancellation of the
contribution of the cosmological constant boundary. The aspects of the behavior
of the generalized models which are not related to the transition are briefly
discussed and the role of the implicitly defined dark energy equation of state
in the description of the dark energy evolution is emphasized.Comment: v1: 9 pages, 6 figures. v2: references added. v3: minor changes.

Geometric origin of scaling in large traffic networks
Large scale traffic networks are an indispensable part of contemporary human
mobility and international trade. Networks of airport travel or cargo ships
movements are invaluable for the understanding of human mobility
patterns\cite{Guimera2005}, epidemic spreading\cite{Colizza2006}, global
trade\cite{Imo2006} and spread of invasive species\cite{Ruiz2000}. Universal
features of such networks are necessary ingredients of their description and
can point to important mechanisms of their formation. Different
studies\cite{Barthelemy2010} point to the universal character of some of the
exponents measured in such networks. Here we show that exponents which relate
i) the strength of nodes to their degree and ii) weights of links to degrees of
nodes that they connect have a geometric origin. We present a simple robust
model which exhibits the observed power laws and relates exponents to the
dimensionality of 2D space in which traffic networks are embedded. The model is
studied both analytically and in simulations and the conditions which result
with previously reported exponents are clearly explained. We show that the
relation between weight strength and degree is , the relation
between distance strength and degree is and the relation
between weight of link and degrees of linked nodes is
on the plane 2D surface. We further analyse the
influence of spherical geometry, relevant for the whole planet, on exact values
of these exponents. Our model predicts that these exponents should be found in
future studies of port networks and impose constraints on more refined models
of port networks.Comment: 17 pages, 5 figures, 1 tabl
Statefinders, higher-order energy conditions and sudden future singularities
We link observational parameters such as the deceleration parameter, the
jerk, the kerk (snap) and higher-order derivatives of the scale factor, called
statefinders, to the conditions which allow to develop sudden future
singularities of pressure with finite energy density. In this context, and
within the framework of Friedmann cosmology, we also propose higher-order
energy conditions which relate time derivatives of the energy density and
pressure which may be useful in general relativity.Comment: LATEX, 11 pages, no figures, version to appear in Phys. Lett.
Nutritivna potpora onkoloŔkih bolesnika
The incidence of malnutrition in cancer patients treated in the intensive care unit (ICU) is significantly higher than in other patient groups.
Hypermetabolism and increased energy requirements resulting from surgery further aggravate nutritional status in malnourished patients and increase the incidence of adverse events including infections, sepsis, wound dehiscence, tissue edema, decubitus and death. The estimation of nutritional status and nutritional needs, compensation for all energy requirements, including vitamin and mineral supplementation using parenteral, enteral or combination of both feeding techniques should become everyday practice in the ICU. Monitoring the success of treatment through laboratory test results and clinical status as well as early recognition of adverse effects of nutritional support minimize the frequency of complications resulting from nutritional therapy.Pojavnost pothranjenosti u bolesnika oboljelih od malignih bolesti koji se lijeÄe u jedinicama intenzivnog lijeÄenja (JIL) je znatno veÄa nego u drugim skupinama bolesnika.
Hipermetabolizam i poveÄane energetske potrebe koji su posljedica operacijskog zahvata dodatno pogorÅ”avaju nutritivni status u pothranjenih bolesnika i poveÄavaju uÄestalost neželjenih posljedica u vidu infekcija, sepse, dehiscijencije rana, edema tkiva, dekubitusa kao i smrtnost. Procjena nutritivnog statusa i nutritivnih potreba, nadoknada svih energetskih potreba, uz suplementaciju vitamina i minerala primjenom parenteralne, enteralne ili kombinacijom obaju tehnika prehrane nužno treba postati svakodnevna praksa u JIL-u. PraÄenje uspjeÅ”nosti lijeÄenja kontrolom laboratorijskih nalaza i kliniÄkog statusa kao i rano prepoznavanje neželjenih uÄinaka nutritivne potpore minimaliziraju uÄestalost komplikacija koje su posljedica nutritivnog lijeÄenja
Multimodalni pristup lijeÄenju poslijeoperacijske muÄnine i povraÄanja (PONV)
The paper shows a new, multimodal approach to the prevention of postoperative nausea and vomiting (PONV), which are among the most common complications in surgically treated patients. The approach combines the following procedures: risk assessment of postoperative nausea and vomiting, minimization of adverse effects of anesthesia and surgery, prophylaxis using drugs with anti-emetic effect, and optimization of therapy in case the complication develops. Besides reducing the incidence rate of PONV, such approach also reduces both the number of PONV-related serious complications and treatment costs.Ovim radom prikazan je novi, multimodalni pristup prevenciji i lijeÄenju postoperacijske muÄnine i povraÄanja (PONV, od engl. postoperative nausea and vomiting) jedne od najÄeÅ”Äih komplikacija koja se pojavljuje u operiranih bolesnika. Objedinjuje sljedeÄe postupke procjenu rizika za razvoj PONV-a, minimaliziranje nepovoljnih uÄinaka anestezije i operacijskog zahvata, preventivnu primjenu kombinacije lijekova sa antiemetskim uÄinkom kao i optimalizaciju terapije ako se komplikacija razvije. Ovom metodom, pored snižavanja uÄestalosti PONV- a, smanjujemo i broj ozbiljnih komplikacija ove pojave kao i troÅ”kove lijeÄenja
