Throughout the history of technological progress, attempts have been made to build a machine that looks and behaves like humans. This paper presents a semi-anthropomimetic robot. The robot structure consists of a human-like upper body mounted on a mobile platform (mobile base, cart). The robot uses the three-wheeled mobile platform with two driving wheels and one passive (caster) wheel. The configuration and model of the upper body are represented as an anthropomimetic, compliant robot with antagonistically coupled drives. Robust control is evaluated in order to ensure stability of the robot position. The aim of this work is not the synthesis of control, but rather the examination of the limits of the adopted robot control strategy and the robot behaviour under disturbances (analysis of tip-over stability). The paper analyses both disturbances from the cart motion and external disturbances due to interaction with the environment (external impulse and long term external force). In order to analyse the balance of the robot and to avoid tipping over, different situations are tested and the appropriate dimensions of the cart are estimated (relying on the ZMP calculation). © 2013 Licensee InTech.

The anti-quorum sensing activities towards the bacterium Pseudomonas aeruginosa PA01 (pyocyanin production, biofilm formation and twitching and flagella motility) of two crude extracts (methanol and acetone) of the freshwater sponge Ochridaspongia rotunda (Arndt, 1937) were evaluated in vitro for the first time. Both extracts demonstrated P. aeruginosa pyocyanin inhibitory activity, reducing its production for 49.90% and 42.44%, respectively. In addition, they both showed higher anti-biofilm activity (48.29% and 53.99%, respectively) than ampicillin (30.84%). Finally, O. rotunda extracts effectively reduced twitching and flagella motility of P. aeruginosa. Taken all together, these results suggest that endemic sponge species from the oldest lake in Europe may offer novel bioactive natural products with promising medicinal potential towards P. aeruginosa infections. © 2014 Taylor & Francis.

Background: The aim of this study was to investigate the cardiovascular mortality in chronic hemodialysis patients (CHPs) and to discover the importance of carotid and femoral artery plaques as cardiovascular (CV) mortality predictor. Methods: In this study with 4 years of follow-up period, we studied a cohort of 101 CHPs. Mean age at entry was 58.1 ± 11.9 years, and mean duration of dialysis was 5.8 ± 5.3 years. We performed B-flow imaging of both carotid and femoral arteries to estimate and score the plaque thickness. Results: The mean carotid and femoral plaque scores (PSs) at entry were 5.02 ± 4.20 and 4.04 ± 3.30 (p = 0.0002). The carotid cutoff point and femoral cutoff point (by ROC curves) were 5.4 and 5.9. The regression coefficients (b) and Exp (b) hazard ratio coefficients of carotid and femoral PS in Cox regression survival analysis in CV outcomes were: b = 0.142, Exp (b) = 1.153, p = 0.0035 versus b = 0.457, Exp (b) = 1.578, p < 0.0001. Relative hazard ratio (HR) risk of exposed group according to CV events was HR 2.812 (CI 1.301–6.081) for carotid PS and HR 2926 (CI 1.424–6.013) for femoral PS. Conclusion: Carotid and femoral plaques are strong independent predictors of CV mortality in CHPs. The HR risk of femoral artery plaques is more predictable than HR risk of carotid artery plaques. © 2016 Springer Science+Business Media Dordrecht

The antimicrobial activity of five crude extracts (aqueous, methanol, ethyl acetate, acetone and methylene chloride) of the freshwater sponge Ochridaspongia rotunda (Arndt, 1937) was evaluated in vitro by using microdilution method against eight bacterial and eight fungal strains for the first time. The extracts were proven to be active in varying degrees against all the bacteria and fungi tested. O. rotunda methanol extract exhibited the highest antibacterial activity (minimum inhibitory concentration (MIC) 7.5-15.0 g/mL and minimum bactericidal concentration 15-30 g/mL), while its acetone extract exhibited the most promising antifungal activity (MIC 7.5-45.0 g/mL and minimum fungicidal concentration 15-60 g/mL). The extracts were more effective against the bacteria and fungi screened compared with the positive controls (streptomycin and ampicillin for bacteria and bifonazole and ketoconazole for fungi, respectively). According to the experimental data obtained, this deepwater sponge species may be considered as a gold mine of new antimicrobial substances with significant and broad-range activity. © 2014 Taylor & Francis.

In recent years, discovering and understanding users' search behaviour attract attention in the research community. Different approaches have been proposed for: 1) learning and modelling how users search; 2) predicting future users' search behaviour patterns, most of them based on statistical analysis and application of data mining techniques on a query log data. In this paper, we focus on the application of the class of generalised stochastic Petri nets (GSPN) on already discovered users' search behaviour patterns, where consecutive actions for query reformulation during the course of a single user session are considered as transitions. An understanding of the motives underlying user actions can help designers to better accommodate to what appears to be chaos: make available those capabilities that best support the range of known behaviour patterns.

This paper gives an analysis of automated guided vehicles navigation systems. Two types of guidance are analysed and simulated by using Lego Mindstorm NXT package - fixed-path guidance through line following as the oldest type and vision-based guidance as a low-cost guidance system that utilises mobile phone camera for tracking marks and detecting obstacles. On the basis of theoretical studies and experience, robot can be programmed in the programming language RobotC in order to demonstrate the functionality of real AGV vehicles.

The aim of this study was to examine the effects of osmotic pretreatment on some physical properties of quinces. Osmotic drying was performed in a saccharose and water solution. The temperatures of osmotic solution were 40 °C and 60 °C, and the initial concentrations were 50 °Bx and 65 °Bx. All four combinations were used in the experiment. High values of the total colour change E* were recorded following the treatment of quince samples with the osmotic solution of 65 °Bx. Lower values of the total colour change were recorded in the same samples after convective drying. Slighter changes in colour after convective drying were caused by a greater amount of solute retained on the surface of the fruit, forming barriers between the fruit tissue and the surrounding air. Mechanical properties of quinces during osmotic drying expressed by the force ratio f = (F0 - Fi)/F0 and modulus of elasticity showed dependence on the temperature of the osmotic solution. At 60 °C, the osmotic solution caused softening of the quince tissue. Thermal softening had a positive influence on the naturally hard quince tissue. The results of the study demonstrate positive effects of osmotic drying on physical properties and quality of dried quinces. © 2015 National Agricultural and Food Centre (Slovakia).

Assuring high quality of web services, especially regarding service reliability, performance and availability of e-commerce systems (unified under the term performability), has turned into an imperative of the contemporary way of doing business on the Internet. Recognizing the fact that customers' online shopping behavior is largely affecting the conduct of e-commerce systems, the paper promotes a customer-centric, holistic approach: customers are identified as the most essential "subsystem" with a number of important, but less well-understood behavioral factors. The proposed taxonomy of customers and the specification of operational profiles is a basis to building predictive models, usable for evaluating a range of performability measures. The hierarchical composition of sub-models utilizes the semantic power of deterministic and stochastic Petri nets, in conjunction with discrete-event simulation. A handful of variables are identified in order to turn performability measures into business-oriented performance metrics, as a cornerstone for conducting relevant server sizing activities. ©2014 Elsevier Ltd.

It is obvious that contemporary man is suffering. His sufferings often seem pointless and causeless. Modern science more and more comes to reveal and acknowledge that human sufferings have a psychosomatic basis. In some of the cases, these sufferings are noogenic neuroses. They do not originate from the psychological dimension but from the noological or spiritual one of human existence. The pointlessness of life is the basic cause for the noogenic neurosis and depression from which the humankind suffers. e. Hence, the many escapes from such experienced reality into various addictions. Possible way towards healing is to retrieve one's meaning of life, to strengthen his will to meaning. Religion has always been - and still remains - a powerful and appealing purpose that fulfills the life and being of the believers. This article demonstrates the systematization of the spiritual development of a person presented in a table of the harmony of the ascetic-hesychastic struggle, according which everyone can find his place on the ladder of spiritual development, become aware, and reconciliate the mode of personal struggle according to his spiritual development. The reconciliation of the primary function of the mind with its secondary function - the intellect, is of an essential importance. Contemporary religious psychology do not regard man merely as a biological or a psychological being. The subject matter of research is the human being as a whole, as a spiritual person that is characterized by autonomy, regarding the biological and psychological processes. The importance of understanding the spiritual level of human existence enables holistic approach and experiencing of the human personality as a whole. Furthermore, it offers new perspectives of psychotherapeutic action not only within the range of the classical psychotherapeutic modalities but also within the range of the applied Christian Psychotherapy.
