In the first part of this text, we define performance-conference as an art form. The concept of performance-conference was examined by Tanya Bruguera. This concept implies that craft can constitute a political attitude. In the introduction, we show that traditional manual labor (through the symbolism of bread, harvest and sourdough) is used and appropriated by right-wing populist dis course in Slovakia. In the second part of this text, we weave a link between Husserlian phenomenology and Sara Ahmed’s queer phenomenology to propose a phenomenological analysis of sourdough. The sourdough is interpreted here as a queer bacterial community that reproduces itself. Finally, we arrive at Myra J. Hird’s concept of hyper-sex, which describes the reproduction of bacteria. The conclusion shows that the reproduction of bacteria (of sourdough) deconstructs the right-wing discourse of traditional heteronormative reproduction. We choose to describe sourdough as queer in order to protest against the compulsory castration of trans people and other forms of oppression of the queer community in Slovakia and the Czech Republic. In this sense, manual labor (the performance, the cook) here constitutes a foundation for political action — in reference to the craftivism movement (Betsy Greer, Kundy Crew).

Le texte propose une analyse de l'acte de manger chez Emmanuel Levinas. Plus spécifiquement, nous nous concentrons sur le manger et le travail. Le manger et le travail sont deux types d’appropriation possibles du monde par l’ipséité. Notre but est de décrire les deux types d’appropriation du monde chez Emmanuel Levinas et de les comparer. On en tirera des possibles conséquences pour une pensée écologique dans la conclusion parce que le manger éfface les frontières entre l'humain et le non-humain. Il s'agit d'un essai écologique de déconstruire le rapport entre l’humain et le monde, qui se montre dans l’acte de manger.

A Polemical Note on Heidegger’s Philosophy

The paper examines the book Buber’s Theopolitics and it analyzes the conflict between the hierarchy in nature and in human society. Buber qualifies our relations to the nature and to other non-living objects as darker than human relations. This creates an imbalance between the human You and the other type of You. This reflection allows us to think what the meaning of the principle of humanity in relation to the personhood is, but also in relation to different forms of communities (natural, or inorganic community). This question is important in the light of the “conflicts” and tensions created by environmental crisis we are facing today. The paper explains how to use the word conflict in this context and whether it is justified.

The aim of this paper is to examine Levinas’ and Derrida’s concept of metaphor. The paper compares their account on metaphor that shows well their position toward religion. Both authors agree that metaphor is connected to the realm of ‘beyond concept’ but Levinas identifies the metaphor, in Carnets de Captivité, with monotheistic divinity. Derrida does not. The conclusion is that Derrida cannot be considered negative theologian nor religious thinker.

The oil content and fatty acid composition were determined in the seed of 19 poppy genotypes (both landraces and modern cultivars) grown in three-year field trials. The total oil content ranged from 34.56-44.76%. The oil content in white-seeded genotypes (40.73-44.76%) exceeded the oil content in blue-seeded genotypes (34.56-40.34%) and ocher-seeded genotypes (38.36-42.69%). Linoleic acid (71.41-74.02%), oleic acid (12.35-15.51%) and palmitic acid (8.95-10.29%) were the most abundant fatty acids in the evaluated seeds of poppy genotypes. A significant negative correlation (-0.7574**) was found between linoleic and oleic fatty acids. The sum of polyunsaturated (PUFA), monounsaturated (MUFA) and saturated (SFA) fatty acids ranged from 72.43-74.91%, 12.90-16.14% and 10.99-12.46% of the total fatty acids, respectively. Both the total oil content and the content of individual fatty acids were mainly affected by the crop year (weather conditions); however, the effect of genotype and year × genotype interaction was also significant. Due to the favourable composition of fatty acids, the evaluated poppy genotypes can be a good source of nutritionally valuable oil.

Three-year field trials were conducted to compare the effect of three tillage systems: strip-tillage (ST), strip-tillage after mouldboard ploughing (STmp) and conventional tillage (CT) on growth and yield of winter oilseed rape at the experimental station in Červený Újezd, Czech Republic. Compared to CT, the growth of roots and aboveground biomass was slower (significantly thinner root necks, shorter roots and leaves) under ST at the beginning of vegetation (BBCH 14-18). Plants under ST still had significantly thinner root necks, and a lower number of leaves than plants from CT before winter (BBCH 21) but the differences were no longer statistically significant in spring (BBCH 30). Despite a slower start, the ST variant with an average yield of 5.47 t/ha significantly exceeded the CT variant with the yield being 5.06 t/ha. Conversely, plants grown under STmp had significantly longer leaves than those under CT in BBCH 14-18 and with the highest values of all parameters, tended to faster growth of biomass, although the other differences were not statistically significant. No differences were observed between STmp and CT in BBCH 21 and 30. The STmp variant achieved the highest yield 5.53 t/ha, and significantly exceeded the CT variant.

The volume reduction of the gray matter structures in patients with Alzheimer’s disease is often accompanied by an asymmetric increase in the number of white matter fibers located close to these structures. The present study aims to investigate the white matter structure changes in the motor basal ganglia in Alzheimer’s disease patients compared to healthy controls using diffusion tensor imaging. The amounts of tracts, tract length, tract volume, quantitative anisotropy, and general fractional anisotropy were measured in ten patients with Alzheimer’s disease and ten healthy controls. A significant decrease in the number of tracts and general fractional anisotropy was found in patients with Alzheimer’s disease compared to controls in the right caudate nucleus, while an increase was found in the left and the right putamen. Further, a significant decrease in the structural volume of the left and the right putamen was observed. An increase in the white matter diffusion tensor imaging parameters in patients with Alzheimer’s disease was observed only in the putamen bilaterally. The right caudate showed a decrease in both the diffusion tensor imaging parameters and the volume in Alzheimer’s disease patients. The right pallidum showed an increase in the diffusion tensor imaging parameters but a decrease in volume in Alzheimer’s disease patients.

This study is oriented to the effect of the incorporation of grape skins and grape seeds (0, 5, 10, and 15% to weight of flour) obtained from a red grape on the rheological properties of wheat dough, and on qualitative parameters and sensory properties of the prepared cookies.

The effects of wheat flour replacement at different levels (5, 7.5, 10, and 20%) by celery root and sugar beet pulp powder on rheological parameters and quality properties of enriched pasta were studied. Sensory evaluation was also investigated. Incorporation of fibre powders increased water absorption and prolonged dough stability and dough development time. Enriched pasta had higher moisture content than control pasta. Addition of fibre powders also modified the cooking quality of pasta (cooking loss and water absorption were increased and optimal cooking time was reduced). Moreover cooked pasta with the higher addition level of celery root powder was characterised by higher intensity of vegetable taste and had pleasant flavour and colour. Sensory evaluation showed that pasta with the addition of 7.5% celery root powder was the most acceptable for assessors.

Pasta is commonly consumed and low glycaemic cereal-based food with long shelf life, which is suitable food matrix for substitution with functional ingredients. Pumpkin powder can be considered as suitable component in pasta making. The effect of addition of pumpkin powder at different levels (5, 7.5, and 10%) on wheat dough rheology, cooking quality of pasta as well as on sensory properties was evaluated. Pumpkin powder included: 6.1% moisture, 8.2%, protein, 0.7% crude fat, 2.3% ash, 27.4% total dietary fiber which is included soluble (10.2%) and insoluble (17.2%) dietary fiber. Farinograph properties of pumpkin powder incorporated dough showed increase in water absorption and dough development time while dough stability and mixing tolerance indes were decreased. It was also observed that addition of pumpkin powder significantly altered cooking quality of pasta. Generally, pasta incorporated with pumpkin powder had shorter optimal cooking time. The shortest optimal time (5.9 min) was after addition of 10% of pumpkin powder compared with control pasta (7.0 min). From the results also concluded that addition of pumpkin powder significantly increased cooking loss. The highest cooking loss (6.6%) was after addition 10% pumpkin powder. Furthermore it could be stated that incorporation of pumpkin powder in pasta increased water absorption of pasta from 181.0% (control) to 211.2% (10% of pumpkin powder). From sensory evaluation resulted that pumpkin powder incorporated pasta were characterized by lower colour, flavor and grain taste. On the other hand vegetable taste and granular structure of pasta increased with higher addition level of pumpkin powder. Moreover, it was concluded that pasta with addition level 10% were the most acceptable for accesors.

The article focuses on the exploration of French philosopher Jacques Derrida's views on literature, emphasizing its relation to deconstruction and its implications for literary theory. Topics discussed include Derrida's critique of traditional conceptions of literariness, the intersection of literature with politics and performativity, and the examination of literary genres and the role of the author in Derrida's thought.

Crackers are a potential material for the addition of cereal germs as a functional ingredient because they are a popular bakery item. The suitability of cereal germs for crackers production was investigated in this study. The effect of cereal germs incorporation to wheat dough (at level 5, 10 and 15%) on the physical properties (specific volume, volume index, width, thickness and spread ratio) and sensory parameters (appearance, firmness, taste, odor and overall acceptability) of cracker were evaluated. It was shown that wheat and corn germ addition to crackers resulted in decreased specific volume from 1.65 cm3.g-1 (control sample) to 1.52 cm3.g-1 (10% corn germs addition) and volume index 3.20 cm (control sample) to 2.57 cm (15% wheat germ), whereas spread ratio increased from 4.71 (fine wheat flour) to 5.06 (15% corn germ). No significant differences were found between the values obtained for width and thickness for crackers supplemented with 5% wheat germ to control sample. Addition of corn germ and wheat germ at level 15% caused decrease volume index of crackers about 13 and 20%. On the other hand enriched crackers of wheat germ and corn germ at level 15% was increment spread ratio by 5 and 7%. Regarding to sensory properties the overall appearance was affected significantly by addition of wheat and corn germ. Higher addition of wheat and corn germ in the crackers adversely affected firmness, taste and odor of final products. In generally, sensory properties of crackers were markedly affected with addition of cereal germs. The most significant differences were observed in appearance of crackers, when the 15% of wheat or corn germs were added (15 and 30% decreasing of this attribute in compare to control sample, respectively). The results of sensory analysis also showed that the crackers incorporated with wheat germs up to 10% level resulted in products with good acceptability.

Surface mulch is an important factor of soil protection technology in the cultivation of potatoes. Presented herein are the results of three years (2009-2011) of field trials at two sites (Leškovice and Uhříněves), where two cultivars (Finka and Katka) were grown. Three mulching treatments (grass mulch after planting, grass mulch before germination and black polypropylene mulch textile) were used in the study. The weight of marketable tubers (tuber over 40 mm) and tuber size distribution were influenced significantly by mulching. The application of grass mulch on surface of the row ensured a 20.5-24.8% increase of weight of marketable tubers and higher occurrence of tubers over 56 mm (resp. tubers 56-60 mm and over 60 mm). There was no consistent effect of grass mulch on the aboveground biomass of weeds. Higher occurrences of larvae of Colorado potato beetle was found on the plots with black polypropylene textile in warmer site Uhříněves.
