Abstract
Background:
Sports and recreational tourism are forms of tourism that imply active involvement of tourists in various sports activities during their vacation, and it can be said that the ...main motive of such a vacation is a sport.
Objectives:
This research aimed to determine the relationship between sports and recreational activities and tourist satisfaction based on the questionnaire related to the behaviour and satisfaction of tourists during their stay in Montenegro.
Methods/Approach:
Regression analysis has been conducted in order to assess the interaction between sport-recreational activities and previous experience in Montenegro, and their effect on tourist revisit intention.
Results:
Empirical results demonstrate the influence of sports and recreational services on tourist satisfaction measured by tourists’ revisit intentions. Distinguishing between sports, and health, spa and wellness facilities and services, the findings indicate that health, spa, and wellness facilities and services have a higher impact on revisit intention than sports activities. In addition, the interaction effect between different sports and recreational activities and previous experience in Montenegro did not provide a more amplified effect on tourist satisfaction.
Conclusions:
Establishing closer links between workers who provide sports services and those providing other tourist services is one of the main challenges in the future of the development of sports tourism in Montenegro, as one of the most critical aspects that can provide tourist satisfaction. The data study can be used for more efficient and effective decision making and strategy development of sports and recreational activities in the tourism industry.
Abstract Background In a previous study we demonstrated that heart variability parameters (HRV) could be helpful clinically as well as a prognostic tool in infants with central coordination ...disturbance (CCD). In recent years, outcome predictions using artificial neural networks (ANN) have been developed in many areas of health care research, but there are no published studies considered ANN models for prediction of cerebral palsy (CP) development. Objective To compare the results of an ANN analysis with results of regression analysis, using the same data set and the same clinical and HRV parameters. Methods The study included 35 infants with CCD and 37 healthy age and sex-matched controls. Time-domain HRV indices were analyzed from 24 h electrocardiography recordings. Clinical parameters and selected time domain HRV parameters are used to predict CP by logistic regression, and then an ANN analysis was applied to the same data set. Input variables were age, gender, postural responses, heart rate parameters (minimum, maximum and average), and time domain parameters of HRV (SDNN, SDANN and RMSSD). For each of one the pairs of ANN and clinical predictors, the area under the receiver operating characteristic (ROC) curves with test accuracy parameters were calculated and compared. Results In the observed dataset, ANN model overall correctly classified all infants, compared with 86.11% correct classification for the logistic regression model, and compared with 67.65% and 77.14% for SDANN and SDNN respectively. Conclusions ANN model, based on clinical and HRV data can predict development of CP in patients with CCD with accuracy greater than 90%. Our results strongly indicate that a well-validated ANN may have a role in the clinical prediction of CP in infants with CCD.
Complex structure experimental analysis has always been a huge challenge for researchers. Conventional experimental methods (e.g., strain gauges) give only limited data sets regarding measurement on ...critical areas with high geometrical discontinuities. A 3D Digital Image Correlation method is an optical method that overcomes the limitations of conventional methods and enables full-field displacement and strain measurement of geometrically complex structures. System Aramis, based on Digital Image Correlation method, is used for experimental analysis and numerical model verification in this paper. Investigated complex structure is sphere/cylinder junction on globe valve housing subjected to axial loading. The highest experimentally measured von Mises strain values around 0.15% are recorded on cylinder/sphere intersection. Von Mises strain values on cylindrical and spherical part are several times smaller than on intersection itself. It is important to emphasize that, to the authors? best knowledge, this is the first paper showing experimental results of 3D full and strain field of geometrically complex structure (sphere/cylinder intersection) on the intersection itself on pressure equipment. It is proven that 3D Digital Image Correlation method is fast and versatile method for recording strain during loading of complex structures.
In this paper is presented that base station output power can be decreased by the power control in each channel. In this case very important is the distribution function of users' density in the ...cell. We present the examples of the cells without power control and the examples of the cells with power control, where the distribution of users' density in the cell is of various types. Some results are compared to the results of measurements, and some to the results obtained by simulation.
Brown rot or bacterial wilt caused by bacterium Ralstonia solanacearum is the main limiting factor in potato production. Quarantine measures are necessary to avoid spread of disease to disease-free ...areas. R. solanacearum has been shown to contaminate watercourses from which crop irrigation is then prohibited causing further potential losses in yield and quality. The bacteria also spread via surfaces that diseased seed potatoes come into contact with. This study showed bactericidal activity of chlorine dioxide (CIO2) on R. solanacearum for disinfection of water, surface and equipment. The results showed that CIO2 solution at concentration of 2 ppm at 30 minutes of exposure time had bactericidal effect for disinfection of water. For surface and equipment disinfection, concentration of 50 ppm showed total efficacy at 30 min and 5 sec exposure time, respectively. Results suggest that use of CIO2 as a disinfectant has a potential for control of brown rot pathogen in water, storage and equipment.
A novel, simple approach for analytical modelling of thermal flow sensors has been implemented. It is based on unification of results obtained using the already developed two-zone analytical model ...and theory of laminar fluid flow over uniformly heated plate. This model can be used in order to extract the main parameters for various geometrical configurations of thermal flow sensors. Presented analytical model was further verified by experimental results. Flow tests were performed using multipurpose MEMS flow sensors consisting of two thermopiles, with 30 p
+Si/Al thermocouples each, and a “U” shaped p
+Si heater. Thermally isolating membrane was formed of sputtered SiO
2 and residual n-Si layer. Experimental evaluation was performed under various flow conditions and applied heating power values. The results showed excellent agreement with theoretical predictions.
Onion (Allium cepa L.) is one of the most important vegetable crops in
Serbia, where it is grown on an approximate surface of 20,000 ha. During the
routine quality control analysis of onion seed in ...2014, fungal infection was
observed in an average of 28% of the seed. The objective of this paper was to
isolate, determine, and identify Fusarium sp. based on the pathogen?s
morphological and molecular characteristics. Onion seed samples were
collected from different localities in the region of Vojvodina. To obtain a
DNA se?quence-based identification, a total DNA of the 25 isolates was
extracted directly from the mycelium (~ 100 mg wet weight), with a DNeasy
Plant Mini Kit (Qiagen, Hilden, Germany). Following DNA extraction, the
translation elongation factor 1-alpha region was amplified by PCR with the
primer pair EF1 and EF2. An amplicon of 700 bp was amplified in 25 tested
isolates. Identification of one isolate was performed by sequencing the
translation elongation factor EF-1? gene, which was deposited in the NCBI
GenBank database under accession number KP658211 (Fusarium sp. FIESC3).
The reduction of commercial and mechanochemically processed CeO2 powders was studied. Nanostructured CeO2, with a crystallite size of 21 nm and the lattice distortion of 0.37%, was obtained during 60 ...min of milling in a high-energetic vibratory mill. XRD, SEM and BET method were used to characterise the milled powders. During thermal treatment at 1200 and 1400 C in an argon atmosphere nonstoichiometric CeO2-x oxides with a defect fluorite structure were formed. Compositions of CeO2-x oxides were determined according to the lattice parameter. The results showed that the release of oxygen, as well as the rate of reduction, was more effective in nanocrystalline than in the microcrystalline CeO2, producing CeO1.80 and CeO1.85 oxides at 1200 C, while at 1400 C CeO1.77 and CeO1.78, compositions were obtained.
During the routine quality control analysis on bean seeds in 2015, Fusarium fungal infection was observed on an average of 17% of the bean seed. The objective of this paper was isolation and ...identification of Fusarium sp. based on the pathogen's morphological and molecular characteristics. Morphological identification of Fusarium isolates was performed on PDA and CLA. DNA of 14 Fusarium sp. isolates was extracted directly from the mycelium (~ 100 mg wet weight), with a Dneasy Plant Mini Kit (Qiagen, Hilden, Germany). Following DNA extraction, the translation elongation factor 1-alpha region was amplified by PCR with the primer pair EF1 and EF2. An amplicon of 700 bp was amplified in all tested isolates. Identification of one isolate was performed by sequencing the translation elongation factor EF-1a gene. Completed morphological and molecular characteristics of isolates, as well as the results of sequencing confirmed that Fusarium proliferatum was the causal agent of bean seed rot.
