Opis:: Fluorescence in situ hybridization (FISH) is a very useful method for assessing chromosome rearrangements. When neither banding pattern nor clinical symptoms are sufficient to determine the origin of additional chromosomal fragment, FISH with multiple chromosome-specific libraries (chromosome painting), allows to solve this diagnostic problem rapidly. Three chromosomal additions, 7q+, 13p+ and 22q+, found in routine cytogenetic studies performed in children with phenotypic abnormalities were analysed using FISH. This technique documented the origin of the extra material to be derived from chromosome 16[der(7)t(7; 16)(q36.3;p 13.11)], 18[der(13)t(13; 18)(p12;q 12.2)] and 22[dup(22)(q11.2q13.1)], respectively. In two cases the abnormality arose de novo, while in the third case the product of translocation t(13;18) was maternal by origin. It was present in 30% of mother's lymphocytes, and in 70% of them a balanced Robertsonian translocation t(13q;15q) was found. In the presented cases the chromosome analysis with both traditional banding and chromosome painting techniques, allowed to establish final clinical diagnosis.

Opis:: Until recently marker chromosomes have presented a difficult diagnostic problem for cytogeneticists as well as for clinicians. Introduction of FISH to cytogenetic analysis has enabled identification of their origin giving possibility to outline specific phenotypic effects of defined marker chromosomes. Nine marker chromosomes were analysed with FISH using centromeric probes, chromosome- specific libraries and unique DNA sequences probes for PWS/AS critical region. The origin from acrocentric chromosomes was established in 6 cases. One marker was a product of maternal 11;22 translocation and two others were pericentromeric regions of chromosome 2 and 4. Among 6 markers, derived from acrocentric chromosomes, 2 consisted of pericentromeric part of chromosome 15, one was identified as mar (21) and in 3 other cases the origin could not be differentiated between chromosomes 13 and 21 or 14 and 22. Clinical consequences of marker chromosomes including the risk for chromosomal nondisjunction and trisomy 21 as well as the risk for uniparental disomy (UPD) are discussed.

Opis:: This study was designed to determine the degree and type of bacterial contamination in boar semen (79 ejaculates from Large White and Landrace boars) and its consequences for sperm quality during storage (27 extended semen samples, 16°C for five days) under practical conditions of artificial insemination (AI). The results revealed the presence of aerobic bacteria in 99% of the ejaculates (from 80 to 370 ×106 colony-forming units/mL). Most of the ejaculates contained two or three bacterial contaminants, while the Staphylococcus, Streptococcus, and Pseudomonas bacterial genera were most frequently isolated. Also detected were Enterobacter spp., Bacillus spp., Proteus spp., Escherichia coli, P. fluorescens, and P. aeruginosa. In general, the growth of certain bacterial types isolated prior to semen processing (Enterobacter spp., E. coli, P. fluorescens, and P. aeruginosa) was not discovered on different days of storage, but fluctuations (with a tendency towards increases) were found in the frequencies of Bacillus spp., Pseudomonas spp., and Staphylococcus spp. isolates up to the end of storage. Semen preserved for five days exhibited decreases in sperm motility and increases in the average number of total aerobic bacteria; this was associated with sperm agglutination, plasma membrane disruption, and acrosome damage. We inferred that, due to the different degrees and types of bacterial contaminants in the boar ejaculates, the inhibitory activity of some antimicrobial agents used in swine extenders (such as gentamicin sulfate) may be limited. Because such agents can contribute to the overgrowth of certain aerobic bacteria and a reduction in the quality of stored semen, procedures with high standards of hygiene and microbiological control should be used when processing boar semen.

Opis:: Nowadays, transportation becomes a significant source, apart from factories and power plants, of air pollution. Therefore, due to legal restrictions on the emission of noxious gases, other power sources for vehicles are necessary. Some of these power sources allow replacement of the internal combustion engine completely, whereas the other ones only support the engine operation. Hence, a hybrid powertrain – alternative to the drivetrain equipped with an internal combustion engine only – is increasingly being used. The hybrid powertrain was mostly applied in cars and buses but recently it has been also used in railway vehicles such as locomotives and multiple units. The paper presents a shortened and brief overview of construction solutions of selected hybrid locomotives. A list of the applied hybrid drive systems as well as the basic data and properties are provided. The most important variants of vehicles are compared. The presented material allows identification of the development trends in the considered area. The hybrid locomotive usually uses an onboard rechargeable energy storage system, placed between the power source and the traction transmission system connected to the wheelsets. Modification of a classic diesel-electric locomotives is a relatively simple procedure since they have all the components of a series hybrid transmission except the storage battery. Therefore, the existing and operated diesel-electric locomotives can be modified to increase their efficiency and reduce operating costs and emissions.

Opis:: The aim of this study was to determine circannual changes in the serum concentrations of thyroxine, calcitonin and parathormone in mature and immature red deer females. Blood samples from 8 hinds were collected monthly for 26 months. Secretions of thyroxine and calcitonin showed circannual rhythms with significantly higher levels in the immature hinds compared to the mature animals (p<0.05). For thyroxine, the concentration was higher in the winter/spring period than in summer/autumn (p<0.05), while for calcitonin the concentration profile was the opposite (p<0.05). The concentration of parathormone was significantly higher in summer/autumn that in the other months of the experiment (p<0.01). These results may indicate that the hormones investigated may be involved in the regulation of seasonal reproductive activity and in processes contributing to entering puberty in red deer females.

Opis:: Research on heat flow in granite sample and sample of aluminium foam with the use of a thermal imaging camera is presented in the paper. Temperature distribution on the surface of the sample as a function of time was obtained on the basis of data from the thermal imaging camera. Thermovision is one of the most universal technology, which is applied for detection of infrared radiation. This technique allows observing and record infrared radiation emitted by objects located in the surrounding environment. This technology allows obtaining, in a short time, temperature distribution on the surface of the sample. The thermograms (pictures showing on the surface of the object) are types of photos showing temperature distribution on the tested object surface which is achieved on the base of a specified range of electromagnetic radiation. Accurate measurement of the temperature distribution on the heated granite sample surface was obtained using a thermal imaging camera FLIR SC 6000. Thermal imaging camera was connected to the computer equipped with control software FLIR ResearchIR Max. Heat source was applied in the experiment as a cast iron hotplate with high efficiency heating, gradual control and 1500W power. Obtained results showed regular temperature distribution over the surface of researched sample.

Opis:: This paper presents an analysis of issues related to the fixed-point implementation of a speech signal applied to biometric purposes. For preparing the system for automatic speaker identification and for experimental tests we have used the Matlab computing environment and the development software for Texas Instruments digital signal processors, namely the Code Composer Studio (CCS). The tested speech signals have been processed with the TMS320C5515 processor. The paper examines limitations associated with operation of the realized embedded system, demonstrates advantages and disadvantages of the technique of automatic software conversion from Matlab to the CCS and shows the impact of the fixed-point representation on the speech identification effectiveness.

Opis:: The railway wagon with a low flat rotatable loading floor was analysed in the paper. Such a structure can be used for transporting various types of vehicles such as tractors, trucks, trailers, semitrailers, cargo containers. The railway wagon allows quick and fast loading and unloading without any platform infrastructure or terminals. Only a hardened flat surface is required. Each railway wagon can be loaded-unloaded individually (no cranes needed). This construction has a wide range of application and is easy to operate. The model of a railway wagon consisted of standard carriages, undercarriages, and a rotatable loading floor was developed. The model was built of rigid solids. Between individual elements of the model, the appropriate joints and contact connections were created. The model was analysed using MSC Adams code, which allows performance of the 3D kinematic - dynamic analyses of the entire model. The analyses were carried out with use of the model of the loaded semitrailer. Passage of the railway wagon with a trailer on horizontal rails, which are the smallest standard arc with a radius 250m, was simulated at different speed. Reactions occurring in couplings of the rotatable loading floor, which are the main element of connection between the rotatable loading floor and motionless undercarriages part of the frame of the wagon, were tested. The maximum velocity at which the railway wagon can move was analysed as well. There was also examined the speed at which the wheels separate from the rails, what results in derailment of the whole wagon.
