The extraction of the new components from electrogastrogram (EGG), using both adaptive filtering and electrocardiographic (ECG) derived respiration signal

Electrogastrographic examination (EGG) is a noninvasive method for an investigation of a stomach slow wave propagation. The typical range of frequency for EGG signal is from 0.015 to 0.15 Hz or (0.015–0.3 Hz) and the signal usually is captured with sampling frequency not exceeding 4 Hz. In this paper a new approach of method for recording the EGG signals with high sampling frequency (200 Hz) is proposed. High sampling frequency allows collection of signal, which includes not only EGG component but also signal from other organs of the digestive system such as the duodenum, colon as well as signal connected with respiratory movements and finally electrocardiographic signal (ECG). The presented method allows improve the quality of analysis of EGG signals by better suppress respiratory disturbance and extract new components from high sampling electrogastrographic signals (HSEGG) obtained from abdomen surface. The source of the required new signal components can be inner organs such as the duodenum and colon. One of the main problems that appear during analysis the EGG signals and extracting signal components from inner organs is how to suppress the respiratory components. In this work an adaptive filtering method that requires a reference signal is proposed.Electrogastrographic examination (EGG) is a noninvasive method for an investigation of a stomach slow wave propagation.

The influence of L-phenylalanine, methyl jasmonate and sucrose concentration on the accumulation of phenolic acids in Exacum affine Balf. f. ex Regel shoot culture

Phenolic acids are an important group of plant secondary metabolites with various, valuable therapeutic properties. Apart from plants growing in the open air, tissue cultures can be an alternative source of the secondary metabolites. The yield of their accumulation in in vitro cultures can be increased by different methods, including culture medium supplementation with precursors, elicitors and changing the standard amounts of the medium components. The purpose of this study was to investigate the influence of the precursor (L-phenylalanine), the elicitor (methyl jasmonate) and a higher sucrose concentration on the phenolic acids accumulation in the agitated shoot cultures of Exacum affine Balf. f. ex Regel (Gentianaceae). Qualitative and quantitative analyses of the phenolic acids in methanolic extracts from the biomass were conducted by applying the HPLC method. Fourteen phenolic acids and cinnamic acid were found in all samples. The total content of free phenolic acids increased from approximately 0.242% to 0.635% (2.6-fold) and the total content of the whole phenolic acids (free and bound) - from 0.712% to 1.160% (1.6-fold). The studies show that the best variant for the accumulation of most of the identified phenolic acids contained 6% of sucrose (double the standard amount), L-phenylalanine 1.6 gL-1 of medium and methyl jasmonate 100 μM. The analysis of the results in the experiment presented here showed that it is possible to increase the accumulation of the phenolic acids in Exacum affine shoot cultures - by adding the precursor (L-phenylalanine), the elicitor (methyl jasmonate) and by increasing the sucrose concentration

The Place and Space of a Donator in Late Medieval Devotional Art The Reciprocal Nature of the Living and the Dead

The first part of this study investigates the supplicants’ relations and interactions based on their position within an artwork. I analyze the importance of being visible and its connection with the act of devotion, as the space that the donor is occupying and sharing with the other depicted figures. I try to find the patterns and the rules governing the ways in which the commissioners are portrayed. To illustrate this aspect, I will use the concept of memoria and care for the here and the hereafter as well as its connection to the donor’s appearance. It is a three-way relation, a kind of pattern of influence where there is a supplicant, a regular churchgoer who is a spectator, and God himself. In the second part of my thesis, I to focus on the commissioners’ place in the society and the significance of being seen not only as a pious but also as a noble, rich and powerful person. The way in which donators attempted to present themselves, both for the here and the hereafter, apparently played a significant role in the medieval devotional art. The third part approaches the question of donators’ visibility for the sake of their salvation. The issue examined is how being a part of sacred narratives influence the time spent in Purgatory and all the actions the donators took in order to be seen. They wanted to be visible, remembered and prayed for. Furthermore, I will present the discussion related to the terminology of patronage in Medieval Art studies. The analysis conducted shows that being visible is strictly connected with the desire of salvation. Depiction, position, place and space of the figures is deeply related to care for the here and the hereafter and the necessity of being close to God hereafter is stronger than vanity in here.Kunsthistorie mastergradsoppgaveMAHF-KUNKUN35

Environmental Impacts on the Success of Bermuda\u27s Inhabitants

The island of Bermuda (32º 20’ N, 64º 45’ W), consists of carbonates interbedded with terra rossa paleosols, situated on top of an eroded shield volcano of mid-to-late Eocene-through-early Oligocene age. The impacts of this distinctive geology, in combination with the island’s isolated geographic setting, have shaped human occupation of Bermuda since it was first settled in 1612. Since the seventeenth century, Bermudian societies have optimized their activities to accommodate their distinctive geologic and geographic setting. Such accommodations include the collection of rainwater as a source of freshwater, the production of sloops out of local Bermudian cedar, the utilization of limestones as well as unique local woods as a building material in the construction of homes and other structures, and the construction and utilization of fishing wells. Other adaptations include a close proximity of buildings on the island so as to accommodate a high population density, the development of a maritime economy, and an emphasis on trade and tourism. The relationship between Bermudian society and its environmental and geographic setting is reflected by this suite of adjustments that have been made by Bermudians throughout the last five centuries which have made it possible for them to thrive on the island. This poster presents these distinctively Bermudian accommodations with reference to their geological and geographical setting, underlining the significant influence setting has played upon the establishment of a successful society

Mechanism of anchoring proteins on the cell envelope

Surface proteins, essential structural components of bacterial cell wall, are synthesized as precursors equipped with specific functional domains. The N-terminal signal module enables translocation across the plasma membrane via Sec or Tat pathways, while sorting motif, located in the C-terminus, is responsible for protein attachment to the cell wall peptidoglycan. Only exception are lipoproteins which lipoylated cysteinyl residue connected with bacterial membrane is in N-terminal part of protein. Most of surface proteins, as surface (S-) layer proteins, internalins or autolysins, are linked to the different structures of cell wall through non covalent forces. From the other hand, molecules with LPXTG motif, which attachment involves sortase activity, are linked to the peptidoglycan by covalent bond. Due to structural, chemical and physicochemical properties, surface proteins are attractive components of diverse industrial or medical systems. Knowledge about mechanism of anchoring proteins to the cell envelope will open new possibility of their applications

Filmowość prozy, prozaiczność filmu. O filmowej adaptacji powieści Jarosława Iwaszkiewicza Sława i chwała

Sława i chwała [Fame and Glory] by Jarosław Iwaszkiewicz has been named as the author’s masterpiece. The work contains autobiographical elements and constitutes a summary of the writer’s ethical experiences, a historiosophical and philosophical synthesis. Only a few reviews have been published concerning the TV series adaptation, directed by Kazimierz Kutz under the auspices of the Polish Television in 1997. The first part of the article (Sensuality recoded) examines the specificity of the imagery of Iwaszkiewicz and Kutz, i.e. the translation of the sensuality of this prose to the language of cinema. Points 2–4 (Antiheroism, “Fame and Glory” as a social panorama, Dilemmas of a 20th-century artist) focus on the reading of the sense of the novel and the way the director relays it on the screen. The final considerations (Infamy) examine the causes of the commercial failure of the adaptation and make an attempt to evaluate the series. It turns out that, despite a modest budget and limited airtime, Kutz has preserved much of the spirit of the original work – it is still the same story about the end of a certain worl
