The subject of this paper is the tourist potential of the gastronomic heritage of ethnic minorities inhabiting Vojvodina (Northern Serbia). The task of the paper is to examine the state of ...authenticity and potential for placement in the tourism market. The goal of the research was to obtain data about the authenticity and representation of authentic and traditional dishes in homes and hospitality facilities and their positioning in tourism. The research was conducted from October 2020 to May 2021 among residents of the region belonging to minority groups (Hungarian, Slovak, Romanian, Croatian, Montenegrin, and Roma). The survey was conducted electronically through cultural, art, and educational institutions that maintain the culture and tradition of the studied ethnic groups. The number of respondents who participated in the research was 619. The obtained data were statistically processed using descriptive statistics, as well as by using t-tests and ANOVA (LSD post hoc), and the reliability of the psychometric scales was assessed by the use of Cronbach’s alpha coefficient. Research has shown that Vojvodina, with its ethnic structure and gastronomic heritage, has the potential to attract tourists motivated by authentic food. Tourism potential of gastronomic heritage are proportionate to the share of ethnic groups; hence, the representation and preservation of the Hungarian, Slovakian, and Croatian cuisines are predominant. The respondents have shown awareness of the activities that would contribute to a better positioning of gastronomic heritage in tourism through implementation in different tourism manifestations and extra marketing activities.
In this paper, we have solved an open problem related to the reverse order laws for
and
-generalized inverses in C*-algebras. It is interesting to note that this problem has only been solved for ...matrices while it still remains open for bounded linear operators. In this paper, we give corresponding results for the case of linear-bounded operators on separable Hilbert spaces.

In this paper, we present some necessary and sufficient conditions for the existence of the (b, c)-inverse and several representations for the (b, c)-inverse related to the group inverse. Since Mary ...inverse, core inverse, dual core inverse and Bott-Duffin (e, f)-inverse are all the special cases of the (b, c)-inverse, related results for these inverses are obtained.
In this paper, we present purely algebraic necessary and sufficient conditions for reverse order laws to hold for {1,2,3} and {1,2,4}-generalized inverses on the set of matrices.
Hemorrhage volume, level of consciousness and ventricular extension and expansion of the hematoma are prognostic factors for clinical outcome of intracerebral hemorrhage (ICH). Volumetric measurement ...of ICH has an important clinical and prognostic meaning. The aim of this study was to compare the methods which are being used to measure ICH volume: the ABC/2 method and semiautomated method with computer volumetric program. Our study represents a retrospective analisys of 54 patients (61.11% male and 38.89% female patients with mean age 67.20±10.30 years) who underwent computed tomography (CT) scan of endocranium. Volumetric measurements were performed by ABC/2 method and computer semiautomated method with volumetric program on Аdvantage Windows 3D Workstation 4.1. Mean value and standard deviation obtained by ABC/2 method were 41.98±35.47, while mean value and standard deviation obtained by computer semiautomated method with volumetric program were 52.12±45.61. There is a statistically significant difference between the values obtained by these two methods (p=0.03). The absolute difference was 10.14 cm3. The values acquired by computer method were by 19.46% higher than those acquired by formula. There is a statstically strong positive correlation between these two methods (r=0.852, p<0.05). Both methods are very useful in determining ICH volume. Our results show that values obtained by computer semiauthomatic method were by 19.46% higher than those obtained by the elliptic equation. Elliptic equation-ABC/2 method is better for measuring regular ICH shapes and fast orientation, while semiautomated computer method is more accurate and more selective.

In this paper we completely answer the following question: for given A∈B(H,K), C∈B(L,K) does there exist X∈B(H,L) such that A+CX is injective? As an application of the obtained results, for given ...operators A∈B(H), B∈B(K) and C∈B(K,H), separate necessary conditions and sufficient conditions on the triple (A,B,C) for the existence of an operator X such that the 2×2 operator matrix MX=ACXB is injective are presented.
