Opis:
The effects of three levels of nutrient concentration solution (1,6; 2,4 and 3,2 E.C.) on the yield and fruit quality of sweet pepper were investigated. It was found that the highest yields on second E.C. level were obtained, while the lowest on the third one. Fruit yield with blossom and rot enhanced with increasing of the nutrient solution concentration. Water consumption by the plant during vegetative period was nearly the same at all three E.C. levels and amounted about 204 dm³ per plant. The fruits contained more vit. C on the third E.C. level. The content of nutrients in leaves usually enhanced with increasing of the nutrient solution concentration level.
Zbadano wpływ stałego podawania w okresie wegetacji trzech poziomów koncentracji pożywki (1,6; 2,4 i 3,2 E.C.) na plon i jakość owoców papryki uprawianej na wełnie mineralnej. Najwyższy plon ogólny i handlowy owoców otrzymano na drugim poziomie koncentracji pożywki, najniższy na trzecim. Plon owoców z suchą zgnilizną był najwyższy na trzecim poziomie koncentracji pożywki. Natomiast zużycie wody przez rośliny było podobne, niezależnie od zastosowanej koncentracji pożywki i wynosiło ok. 204 dm³/rośl. Zawartość składników mineralnych w liściach papryki zwykle rosła wraz ze zwiększaniem się koncentracji pożywki.

Opis:
The sonar based on cylindrical transducer compared with linear transducer has few advantages. Particularly its omni-directional central symmetry enables simplification of the echo signal Direction of Arrival (DOA) estimation. When the number of transducer staves is the power of two the efficient Fast Fourier Transformation can be used to calculate spatial convolution. The article presents theoretical and technological principles of the real time digital data processing of the wideband echo signals received by cylindrical hydroacoustic transducer. Described procedures enable high resolution underwater target location and precise data display. The implementation of effective broadband pulse compression technique with high range resolution will be presented. The results of signal processing modeling and examples of application will be also discussed.

Opis:
A packet buffer limited to a fixed number of packets (regardless of their lengths) is considered. The buffer is described as a finite FIFO queuing system fed by a Markovian Arrival Process (MAP) with service times forming a Semi-Markov (SM) process (MAP/SM/1/b in Kendall’s notation). Such assumptions allow us to obtain new analytical results for the queuing characteristics of the buffer. In the paper, the following are considered: the time to fill the buffer, the local loss intensity, the loss ratio, and the total number of losses in a given time interval. Predictions of the proposed model are much closer to the trace-driven simulation results compared with the prediction of the MAP/G/1/b model.

Opis:
The hydroacoustic system based on DOA estimation utilizes passive antenna composed of many hydrophones. The samples of the arriving acoustic signal must be gathered synchronously from each hydrophone. This enables to take advantage of parametric processing signals methods. These methods make possible determination of the amplitude and the phase relationship among particular hydrophones. The newest complex systems made up of many sub modules uses network solutions. In the case of Ethernet network some standards (e.g. Precision Time Protocol) are defined to enable synchronization of the data (samples) gathered from many hydrophones by the clock synchronization. When the antenna consists of few hydrophones then the special concentrator connected point-to-point to hydrophones can be utilized. This article discusses the issue related to PTP as well as concentrator based on FPGA technology, which uses simple UDP protocol. In the case of concentrator the synchronous method of the I/Q detection which not requires synchronous samples acquisition is also presented.

Opis:
Despite the increasing availability of measured laser scanning data and their widespread use, there is still the problem of rapid and correct numerical interpretation of results. This is due to the large number of observations that carry similar information. Therefore, it is necessary to extract from the results only the essential features of the modelled objects. Usually, it is based on a process using filtration, followed by simplification and generalization of redundant contents of datasets. This process must ensure the collection of new data without loss of information contained therein, the description accuracy of the key features of a measured object, as well as the uniqueness and comparability of results. In this paper, the authors extend the already extensive range of algorithms for the automatic or semiautomatic modelling of cylindrical objects, which have been measured using the laser scanning technology, with the one employing a concave hull or - in general - the alpha-shape (α-shape). The applicability of the proposed method was analysed using simulated data - generated analytically with the introduced and established systematic error with normal distribution - and using real results of the measurement of cylindrical-shaped objects. For real data, the obtained results were compared with the reference data. This made it possible to determine the validity of the proposed new method.

Opis:
Physical activity is a natural need of a human organism in every stage of the onthogenesis. It is especially indispensable for the proper physical and mental development in childhood, in youth as well as in adult life. Usually it the person’s interests and capabilities that determine the form of their physical activity. Among the most popular disciplines nowadays are: table tennis, skiing, gym exercises, gymnastics, roller–skating, football, swimming, jogging as well as water sports such as rowing. There are many benefits that come from any form of physical activity. The purpose of this research was to determine factors that affect young people’s decision to take up rowing. The research has been carried out on three social groups: active rowers – athletes (20 women and 19 men) at the age of 15–21, all members of Poznań rowing clubs; students of primary and secondary schools in Poznań (72 girls and 68 boys) at the 13–14; as well as adult inhabitants of Poznań (51 women and 52 men) at the age 30–45. The research was carried out with the help of a diagnostic poll (author’s questionnaire) comprising 17 questions regarding knowledge about the discipline, the discipline’s popularity as well as the influence of media on the decision as to the form of physical activity. Over the last few years the number of rowers has decreased significantly in spite of considerable international success of Polish rowers. The reasons for youth not taking up any physical activity may lie in incorrectly prepared range of activities that rowing clubs have to offer as well as in insufficient means taken to inform society about this sport. It seems that new methods of reaching potential future athletes should be used, e.g. by means of the Internet and social media.

Opis:
The study raises the issues concerning the automatic system designed for the monitoring of movement of controlled points, located on the roof covering of the Forest Opera in Sopot. It presents the calculation algorithm proposed by authors. It takes into account the specific design and location of the test object. High forest stand makes it difficult to use distant reference points. Hence the reference points used to study the stability of the measuring position are located on the ground elements of the sixmeter-deep concrete foundations, from which the steel arches are derived to support the roof covering (membrane) of the Forest Opera. The tacheometer used in the measurements is located in the glass body placed on a special platform attached to the steel arcs. Measurements of horizontal directions, vertical angles and distances can be additionally subject to errors caused by the laser beam penetration through the glass. Dynamic changes of weather conditions, including the temperature and pressure also have a significant impact on the value of measurement errors, and thus the accuracy of the final determinations represented by the relevant covariance matrices. The estimated coordinates of the reference points, controlled points and tacheometer along with the corresponding covariance matrices obtained from the calculations in the various epochs are used to determine the significance of acquired movements. In case of the stability of reference points, the algorithm assumes the ability to study changes in the position of tacheometer in time, on the basis of measurements performed on these points.

Opis:
Over the last few years the interest for the so-called healthy lifestyle motivated by the fitness ideology has increased significantly. However, there is still little research concerning this question, especially with regard exercises in water. The purpose of this research was the comparison of the reason of women’s participation in different forms of physical activity such as aerobics and aqua aerobics classes, and whether the reasons for taking up this activity were related to health problems, place of residence or perhaps totally random. The research included 140 women who took part in 60-minutes long aerobics and aqua aerobics classes. The research was carried out by means of a statistical poll using a questionnaire. Among the main factors influencing the women’s decision to take up some kind of physical activity are: better life quality, lower stress level, better well-being, beneficial influence sports have on their health as well as improvement in physical appearance. It has been found out that regardless of the place of exercise, the motivation for taking up aerobics are similar for all women included in the research. The choice of place is motivated by their health capabilities and the environment they live in.

Opis:
Information on the prevalence of subclinical endometritis and its mechanism in repeat breeding cows is very limited. The aims of this study were: a) to evaluate the incidence of this disorder with cytobrush cytology b) to analyze mRNA expression of tumor necrosis factor α (TNFα) and inducible nitric oxide synthase (iNOS) in endometrial biopsy samples collected from repeat breeding cows with and without subclinical endometritis. Two experiments were carried out. In experiment 1, 112 (12.4%) repeat breeding cows (inseminated at least 3 times and not pregnant) were selected out of 902 cows from 8 dairy herds. Cytobrush cytology was performed on these cows, using the threshold of 10% PMNs in uterine smears. The results showed that 45 out of the 112 cows (40.2%) were diagnosed as having subclinical endometritis. In experiment 2, uterine biopsy samples were taken from repeat breeding cows with subclinical endometritis (n = 10) and without this disorder (n = 10). Using reverse transcription-PCR, the mRNA expression of TNFα and iNOS was determined. A statistically significant increase in expression of both substances was measured in the group of cows with subclinical endometritis (p < 0.05). These results provide evidence for a high prevalence of subclinical endometritis in repeat breeding cows as well as the involvement of TNFα and iNOS pathways in the regulation of this pathological condition.

Opis:
The paper proposes a No-Reference (NR) quality assessment measurement originally developed for H.264, used for High Efficiency Video Coding (HEVC). In particular, authors present an investigation of NR metrics to objectively estimate the perceptual quality of a set of processed video sequences. The authors take into account typical distortions introduced by the block-based coding approaches like HEVC codec. The underlying processing used for the quality assessment considers the blockiness caused by the boundaries of each coded block and the blurring as a lack of spatial details. The correlation between the NR quality metrics and the well-known and most widely used objective metric, the Video Quality Model (VQM), is performed to validate the quality prediction accuracy based on the provided scores. The Pearson correlation coefficients obtained stand for promising results for different types of videos.

Opis:
The rapid development of scanning technology, especially mobile scanning, gives the possibility to collect spatial data coming from maritime measurement platforms and autonomous manned or unmanned vehicles. Presented solution is derived from the mobile scanning. However we should keep in mind that the specificity of laser scanning at sea and processing collected data should be in the form acceptable in Geographical Information Systems, especially typical for the maritime needs. At the same time we should be aware that data coming from maritime mobile scanning constitutes a new approach to the describing of maritime environment and brings a new perspective that is completely different than air and terrestrial scanning. Therefore, the authors, would like to present results of an experiment aimed at testing the possibilities of using mobile scanning at sea. Experiment was conducted in the harbour and the associated environment of neighbouring southern coast of the Baltic Sea.

Opis:
The aim of this research was to determine the effect of thermal conversion temperature and plant material addition to sewage sludge on the PAHs content and the activity of selected γ-radionuclides in biochars, and to conduct an ecotoxicological assessment. The pyrolysis of the mixtures of sewage sludge and plant materials at 300°C and such temperature caused an increase in the contents of 2- and 3-ring hydrocarbons. During the pyrolysis of organic materials at 600°C, the amount of the following compounds was reduced in biochars: benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3c,d]pyrene, dibenzo[a,h]anthracene, and benzo[g,h,i]perylene. Among γ-radioisotopes of the elements, natural radiogenic isotopes were dominant. 137Cs was the only artificial radioactive isotope. The pyrolysis of the mixtures of municipal sewage sludge and plant materials revealed that isotope  40K had the highest radioactive activity. In the case of other analysed nuclides, activities of  212Pb,  214Pb,  214Bi, and  137Cs were determined after the sample pyrolysis. The extracts from the mixtures of sewage sludge and plant materials were non-toxic to Vibrio fischeri.
