Angioleiomyosarcoma – a very rare malignant tumour from the soft tissue

In the article we describe a case of a 12-year old boy with the tumour in the small pelvis. The only one abnormality in laboratory tests was a 3-numeral ESR and a big solid tumour probably extended from the urine bowel, found on radiological examination. On surgery the tumour was found to extend from the ascendent colon. On pathological examination, it was described as angioleiomyosarcoma with metastases in the lymph nodes. The boy was treated with IX courses consisting of ifosfamide, vepeside or ifosfamide, adriamycine and vincristine. At present, the child is in the first complete remission, 7 months after completion chemotherapy

Keratin and S100 calcium-binding proteins are major constituents of the bovine teat canal lining

The bovine teat canal provides the first-line of defence against pathogenic bacteria infecting the mammary gland, yet the protein composition and host-defence functionality of the teat canal lining (TCL) are not well characterised. In this study, TCL collected from six healthy lactating dairy cows was subjected to two-dimensional electrophoresis (2-DE) and mass spectrometry. The abundance and location of selected identified proteins were determined by western blotting and fluorescence immunohistochemistry. The variability of abundance among individual cows was also investigated. Two dominant clusters of proteins were detected in the TCL, comprising members of the keratin and S100 families of proteins. The S100 proteins were localised to the teat canal keratinocytes and were particularly predominant in the cornified outermost layer of the teat canal epithelium. Significant between-animal variation in the abundance of the S100 proteins in the TCL was demonstrated. Four of the six identified S100 proteins have been reported to have antimicrobial activity, suggesting that the TCL has additional functionality beyond being a physical barrier to invading microorganisms. These findings provide new insights into understanding host-defence of the teat canal and resistance of cows to mastitis

The EOG event recognition method in an EEG signal towards SSVEP BCI improvement

This paper presents a method of recognizing EOG artifacts in an EEG signal. Moreover, it shows the possibility of determining the direction of eye movement. The idea behind this method is to develop a hybrid brain-computer interface relying on SSVEP phenomena and EOG artifacts acquired from the EEG signal. Recognition of an EOG event and its direction can be used to improve the SSVEP detection accuracy, overall system responsiveness, and increase the information transfer rate (ITR). Eye movement direction is recognized using a decision tree and histogram-based features calculated from EEG signals recorded in Fp1-O1 and Fp2-O2 points. The accuracy of 75% was achieved for a group of 8 subjects, while the average precision of detecting movement direction in horizontal plane was 78%

A R C H I V E S of F O U N D R Y E N G I N E E R I N G The technology of recovery melting of steel for turbine castings in induction furnace

Abstract A technology of recovery melting of G17CrMo 5-5 and G17CrMoV 5-10 steel for turbine castings in induction furnace followed by ladlefurnace refining (EIF+LF) was evaluated. Studies included testing of molten steel metallurgical purity, mechanical tests and evaluation of benefits for both economy and ecology resulting from the introduction of new technology. It was concluded that using the EIF+LF technology for production of massive castings of large overall dimensions (26Mg) has brought numerous multi-level advantages

Industrial hemp grown in remediated land used for energy

Biomasa jest surowcem energetycznym, której spalanie, w przeciwieństwie do paliw kopalnych, nie powoduje zwiększania się bilansu emisji CO2 do atmosfery. Dwutlenek węgla emitowany podczas spalania biomasy jest absorbowany w fazie wzrostu rośliny. Z prowadzonych badań wynika, że 1 hektar (ha) upraw konopi wiąże około 2,5 tony CO2. Konopie charakteryzują się wysokim plonem biomasy wynoszącym nawet 15 t/ha.Biomass is an energy feedstock which, unlike fossil fuels, contributes no additional CO2 amounts to the atmosphere. Carbon dioxide emitted during combustion of biomass is absorbed during the plant growth. The research results show that 1 hectare (ha) of hemp assimilates approximately 2.5 t of CO2. Hemp is characterized by high biomass yield reaching even 15 t/ha

A test bench setup with programmable trajectory for IMU-based dataglove development

This paper presents a test bench created during development of an IMU-based dataglove. The system allows gathering synchronised hand phantom posture and trajectory, together with inertial sensor data for evaluation of posture recognition algorithms. The setup includes an inertial measurement system, with IMU modules designed to be mounted on human hand or a phantom, together with proper embedded firmware and PC software. The system uses a collaborative Universal Robots UR3 robot arm for generation of trajectories and as a source of ground truth data. The program used to control the robot together with a method of gathered data synchronisation are described. The test bench has been successfully used during development of a joint angles estimating algorithm
