Opis:
Analysis of the shape and location of abrasive grain tips as well as their changes during the grinding process, is the basis for forecasting the machining process results. This paper presents a methodology of using the watershed segmentation in identifying abrasive grains on the abrasive tool active surface. Some abrasive grain tips were selected to minimize the errors of detecting many tips on a single abrasive grain. The abrasive grains, singled out as a result of the watershed segmentation, were then analyzed to determine their geometric parameters. Moreover, the statistical parameters describing their locations on the abrasive tool active surface and the parameters characterizing intergranular spaces were determined.

Opis:
The completely new strategy of pseudophysiological transcomplementary (transcytoplasmic) activation (PP-TCA) of nuclear-transferred oocytes, which had been derived from pWAPhGH-GFPBsd transfected foetal fibroblast cells, was recently applied to the somatic cell cloning of pigs. It resulted in the considerable enhancing not only the cleavage activity of cultured cloned embryos, but also their morula and blastocyst formation rates as compared to the use of standard simultaneous fusion and electrical activation of reconstituted oocytes (77% vs. 57%, 63% vs. 46% and 40% vs. 27%, respectively). Altogether, the use of cytosolic components descended from heterologous (rabbit) zygotes as the agents for stimulation of porcine clonal cytoplasmic hybrids (cybrids) turned out to be reliable and feasible strategy for the generation of transgenic blastocysts by somatic cell nuclear transfer (SCNT). Furthermore, to our knowledge, no previous study has reported the preimplantation developmental outcome of transgenic nuclear-transferred pig embryos following the PP-TCA that was developed and optimised in our laboratory.

Opis:
The use of artificial neural networks for modelling and inference about surface parameters is a more and more often undertaken research topic. Based on the analysis of the ranges of suitability of surface topography parameters, a variety of different parameters can be observed to identify surfaces with different features and different conditions of use. The issues of surface topography analysis and determination of surface condition after abrasive machining are of fundamental importance. Currently, when assessing the surface intended for interaction with the other surface, it is possible to use many surface evaluation parameters. Assigning the machined surface to the appropriate assessment group, especially in automated quality control systems, requires a preliminary surface classification. In this article Hamming's network was used for the surface classification along with modification of Hamming distance.

Opis:
Grinding is one of the basic precise machining methods. Evaluation of the abrasive tool surface is the basic criterion of forecasting the tools' durability and the process results. The applied method of laser scanning made determination of the surface coordinates and subsequently of its geometric features with micrometric accuracy possible. Using the information on the abrasive tool surface geometric structure, a methodology of evaluation of the level of changes of the tool during the machining process was developed. The developed method allowed for evaluation of the level of abrasive tools' wear, and subsequently formed foundations for assessment of the influence of the machining parameters on the durability of abrasive tools, evaluation of the influence of the parameters of the process of shaping the abrasive tools' active surfaces on their geometric characteristic and evaluation of the level of correlation between the monitored process parameters and the degree of the abrasive tools' wear.

To investigate the classification ability, variance and geometric mean of the ordered differences of the parameter value. The study compares behaviour of both indices for different distributions of ordered differences of the parameter value. Moreover, the relationship between bot indices and influence of the number of minor differences of the parameter value on the value of variance and geometric mean.

Opis:
Analysis of the geometric features and determination of the condition of the surfaces machined during an abrasive process is of crucial importance for evaluation of their wear properties. Numerous parameters can be used for assessing topography of technical surfaces. Many of them contain information that is general or poorly correlated with the wear features. The group of parameters used for such purpose should include those that do not cause information redundancy and provide distinct information. Evaluation of the surface geometric structure after precision machining is a difficult process due to the limited scope of unevenness heights that fit within the range of a few micrometers to a few nanometers. In this paper the synthetic indexes of the evaluation of extra smooth surfaces were created, taking into consideration numerous elementary parameters. The value of the synthetic index was determined as the geometric average of the partial indexes which, when compared to the arithmetic average, is more dependent on the data believed to be disadvantageous.

Opis:
A section of research concerning the development of a model to enable predicting the hardness profiles in the nitrided layer, based on an artificial neural network, was presented in this paper. In the developed model a unidirectional two-layer neural network was applied. The designed network possesses good capacities to generalize the knowledge included in the experiential data. Matching the model with the training data made it possible to determine, with a good approximation, the hardness profiles, which make up a set of verifying data.
W pracy zamieszczono wyniki fragmentu badań dotyczących opracowania inteligentnych narzędzi wspomagających procesy obróbek powierzchniowych. Badania obejmowały opracowanie modelu statystycznego, opartego na sztucznej sieci neuronowej, umożliwiającego prognozowanie profili twardości w warstwie azotowanej. W opracowanym modelu zastosowano jednokierunkową dwuwarstwową sieć neuronową. Zaprojektowana sieć neuronowa posiada dobre zdolności uogólniania wiedzy zawartej w danych eksperymentalnych. Zaobserwowano ścisłą korespondencję między przewidywanymi profilami mikrotwardości na podstawie modelu oraz danymi eksperymentalnymi.

Opis:
Extinct aurochs (Bos primigenius), accepted as the ancestor of domestic cattle, was one of the largest wild animals inhabiting Europe, Asia and North Africa. The gradual process of aurochs extinction finished in Poland in 1627, were the last recorded aurochs, a female, died. Some aspects of cattle domestication history and the distribution of aurochs genetic material among modern cattle breeds still remain unclear. Analyses of ancient DNA (aDNA) from bone sample deliver new genetic information about extinct wild aurochs as well as modern cattle phylogeny. DNA was extracted from a fragment of aurochs fossil bone found in the Pisz Forest, Poland. The sample was radiocarbon-dated to about 1500 yBP. The aDNA was used for Whole Genome Amplification in order to form a DNA bank. Auroch mitochondrial DNA sequences were amplified using sets of 41 primers overlapping the whole mtDNA, cloned and sequenced. The sequence of the whole mitochondrial genome was reconstructed and deposed in GenBank [GenBank:JQ437479]. Based on the phylogenetic analyses of the Bovine mitochondrial genomes, a phylogenetic tree was created. As expected, the tree clearly shows that the mtDNA sequence of the analyzed PWA (Polish Wild Aurochs) individual belongs to haplogroup P. In the course of the comparative mtDNA analysis we identified 30 nucleotide marker positions for haplogroup P and nine unique PWA differences compared to the two remaining haplotype P representatives. Our analysis provides the next step to the reconstruction of the demographic history of this extinct but still exciting species.
