Streszczenie:

Carpet textures contain periodic information that varies across constructions and is degraded by mechanical wear. We apply image covariance, a digital implementation of mathematical morphology, to binary carpet images for the purpose of measuring aspects of texture periodicity. Our test materials consist of four kinds of double ply wool carpets of differing textures divided into control, light, and heavy wear samples. Video images were digitized by a True Vision Vista frame grabber. Gray-level images were histogram equalized and converted to binary. Covariance data allow one to measure period frequency, amplitude, and overall mean. Results for our carpet samples show changes in amplitude and mean with wear, and are consistent with findings for a previous paper using grey level co-occurrence analysis. Covariance analysis requires relatively minimal computation for processing and preprocessing, but results may be affected by loss of gray level gradient information. If textural features of interest are preserved, this method is an efficient and easily implemented alternative to co-occurrence analysis. Attention is also given to the covariance analysis of computer generated carpet-like textures. We attempt to duplicate the covariance behavior of our carpet series by altering the placement of the component texture objects and simulate carpet wear by degrading regular textures with noise. We offer some thoughts on modeling carpet texture appearance loss with the aid of simulated texture images.

Since their discovery, carbon nanotubes received a great deal of attention because of unique physical and chemical properties. However, in order to become of interest in the field of super resistant fibers for nanocomposite materials or in the production of textile material, very long carbon nanotubes are needed. Massive samples of well packed, vertically aligned and very long selfstanding multi wall carbon nanotubes (MWNT) were synthesized on uncoated silicon by a very efficient thermal CVD process, which involved the co-evaporation of camphor and ferrocene in a nitrogen atmosphere. We obtained structures with diameter between 20 and 80 nm with an average growth rate of about 400 nm/s, organized in thick carpets of entangled nanotubes. By the weight of the deposited carpet of MWNTs (density circa 0.8 g/cm3) the conversion of about 30% of the total hydrocarbon feedstock was calculated. Morphology and physical properties were characterized by electron microscopy techniques, Micro- Raman spectroscopy and thermogravimetric analysis. The analyses performed showed the absence of secondary carbonaceous products, whereas only 6% in weight of ferromagnetic iron clusters are present. BET analysis was used to calculate the porosity and the specific surface area density of the as grown samples, which resulted approximately 70 m2/g. Hydrophobicity of the CNT carpet was also investigated.

Abstract The scientific objective of this work is to reuse the polymer materials generated from carpet waste. The nylon obtained from the discarded carpet was used as reinforcement material into the epoxy matrix phase. A modified approach of Vacuum-assisted resin transfer molding (VARTM) was used to infuse the mixture of epoxy and hardener into the nylon carpet polymer composites. This investigates the water absorption behavior of carpet waste composite. It will justify the application of proposed composites for lightweight structural applications in a moisture environment. The nylon fiber-based-epoxy composite was dipped in water as per ASTM standard for a different duration, namely, 24, 48, 72, 144 hours. The findings demonstrate that it can effectively withstand in moisture environment, and a maximum 4.5% weight of samples increased among all the samples for a different duration. Also, the developed composite showed a lower water diffusion co-efficient than the nail head structure and linden wood. Also, the carpet waste composite samples were investigated for thermal degradation and chemical behavior using X-Ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, respectively. The finding shows that the proposed composite could be used for lightweight components such as dashboard panels, sound absorbers, panel sheets, wall tiles, etc.

Carpet shell clam populations on the Tunisian coastline are susceptible to several microbial pathogen challenges. In this study we report the results of five years' surveillance, conducted from January 2004 till June 2009, for detection of Perkinsosis and brown ring disease (BRD). The survey covered three sites of natural populations of Ruditapes decussatus in a Tunisian lagoon, the North Lake of Tunis. Perkinsosis was detected preferentially in winter periods from the external and marine site, BRD was detected more frequently in the summer periods in a more proximal collection site (in the lake) and was positively correlated with concentrations of heterotrophic Vibrio sp. Our results suggest that several factors other than temperature and salinity might explain spatial distribution variability and natural intensities for these infections in carpet shell clam populations.

Streszczenie:

Supported metal nanoparticles form the basis of heterogeneous catalysts. Above a certain nanoparticle size, it is generally assumed that adsorbates bond in an identical fashion as on a semiinfinite crystal. This assumption has allowed the database on metal single crystals accumulated over the past 40 years to be used to model heterogeneous catalysts. Using a surface science approach to CO adsorption on supported Pd nanoparticles, we show that this assumption may be flawed. Near-edge X-ray absorption fine structure measurements, isolated to one nanoparticle, show that CO bonds upright on the nanoparticle top facets as expected from single-crystal data. However, the CO lateral registry differs from the single crystal. Our calculations indicate that this is caused by the strain on the nanoparticle, induced by carpet growth across the substrate step edges. This strain also weakens the CO–metal bond, which will reduce the energy barrier for catalytic reactions, including CO oxidation.

In this paper, a straightforward yet effective design methodology to design wideband antenna with band notched characteristics has been proposed. Sierpinski carpet fractal geometry has been used to realize the antenna structure. Co-planar waveguide feed is used with a novel structure to achieve larger impedance bandwidth and band notching characteristics. Proposed antenna is designed using High Frequency Structure Simulator (HFSS) on a low cost FR4 substrate (ɛr=4.4) which resonates at three frequencies 1.51 GHz (1.19-2.06GHz), 6.53 GHz and 8.99 GHz (4.44-9.54 GHz) while a band is notched at 10.46 GHz (9.32-11.92 GHz). The proposed antenna has an electrical dimension of 0.36 λm× 0.24 λm, here λm is the wavelength with respect to lowest resonating frequency of the antenna. The resonating and radiation characteristics of the antenna are verified experimentally. Further, investigations are made to achieve easy integration of the antenna to the monolithic microwave integrated circuits. For that the antenna has been designed on micro-machined high index Silicon substrate which improve matching and gain of the antenna. The results of the micro-machined Sierpinski carpet fractal antenna are highly convincing over the conventional FR4 based antenna.

Umberto Eco’s ideas and philosophy have proven to be a profound inspiration to the research team dedicated to the recently completed qualitative interdisciplinary research project ‘RHYME: rhythm & rhyme; co-creation through tangible interaction’, in which both of the present authors participated. The idea of RHYME is that ordinary objects in the home environment – a pillow, carpet or toy, for example – if they should become both musical and interactive, might afford meaningful, joyful and even health-promoting moments of co-creation in the everyday lives of families with a child with disabilities. This article develops the central RHYME notion of co-creation further by introducing it to music therapy. From our experiences with interactive and musical media from RHYME, and inspired by Eco and his notions of ‘open works’ and ‘fields of possibilities’, we have developed an understanding of music therapy as a configuration of possible events or interactive structural forces. Music, then, becomes one of many possible media in music therapy. Through a reflective synthesis which also includes the discussion of empirical RHYME data, we will address the following research question: Can Eco’s notions contribute something new to our understanding of co-creation in music therapy, and, if so, what and how?

An indoor environment survey (temperature, relative humidity, illuminance, noise, infrasound, CO, CO2, formaldehyde, respirable dust weight, particle counts, mite allergen in carpet or chair dust, individual and total volatile organic compounds, individual and total microbiological volatile organic compounds) was conducted in 4 office buildings. A detailed self-report occupant comfort, ergonomic conditions and SBS questionnaire survey was administered to all employees, and 1,508 returns were received (72% return rate). There were few associations between specific SBS symptoms and specific environment measures were found, but total SBS symptoms were not correlated with most of the indoor environment measures. There was a significant difference in SBS reports between areas above and below 650 ppm CO2. SBS symptoms were correlated with perceived indoor environment conditions, cacosmia, overwork, migraine, allergies, and musculoskeletal complaints. SBS symptoms were not associated with negative affect, worry, or general anxiety and stress.

The subject of the article are certain idiomatic expressions constructed with the adjective perski (‘Persian’) in Polish: perskie oko (‘Persian eye’), perski dywan (‘Persian carpet’), perski proszek (‘Persian powder’) etc. Moreover, the author attempts to answer the question: What do we have that is really Persian in Polish? Are these phrases really related to Persia or Persians, or are they just a word game (homophones)? So far the origin of the most popular one, i.e. perskie oko (‘Persian eye’) has not been established even though a lively discussion on this subject was held on the pages of the Język Polski 90 years ago. It was started by Stanisław Szober who in his book Życie wyrazów, explained the origin of the phrase perskie oko for the first time, indicating that it is a semantic borrowing from French, and its basis is l’œil perçant ‘piercing eye’. In response, Józef Birkenmajer claimed this popular phrase comes from Krakow, relating it – quite incredibly – to a Persian man on the label of the popular Zacherlin insecticide powder called perski proszek (‘Persian powder’). It turns out that the source of this expression was a French anecdote by Alphonse Karr from the late nineteenth century based precisely on the word game.

La raza ovina Criolla es la fundadora del patrimonio ovino argentino y está distribuida en casi todas las provincias. Son pocos los trabajos destinados a estudiar la calidad lanera de este germoplasma. El objetivo fue caracterizar la lana de ovejas Criollas Argentinas, utilizando las principales medidas que determinan su calidad y su valor comercial. El muestreo se realizó sobre majadas ubicadas en cuatro provincias: Salta (SA) (n= 44); Santiago del Estero (SE) (n= 60); Corrientes (CO) (n= 40) y Buenos Aires (BA) (n= 59). Se tomaron muestras de lana de cada oveja y se determinaron las siguientes variables: diámetro medio de fibra (DMF); desvío estándar del diámetro medio de fibra (DE_DMF); curvatura de ondulación (CU); factor de confort (FC) y largo de mecha (LM). El análisis estadístico incluyó análisis de varianzas (ANOVA), análisis de componentes principales (ACP) y de conglomerados (ACO). Las ovejas SA se destacaron del resto de las regiones por su menor DMF= 26,1±2,5 µm y DE_DMF= 6,2±1,5 µm, su mayor CU= 78,5±13,5 º/mm y su mayor FC= 78,8±12,7 %, mientras que las de BA presentaron un LM= 123,0±36,6 mm, ampliamente superior a las otras regiones y CO presentó mayor DMF= 35,9±4,1 µm. El ACP identificó 2 componentes que explicaron el 90 % de la variabilidad. La primera diferencia SA de BA y muestra superposición entre SE y CO. La segunda diferencia BA del resto de las regiones. Del ACO surge que los ovinos de SE y CO forman un solo grupo definiéndose tres regiones: SA, BA y SE-CO. Ninguno de los tres grupos respondió a la categoría carpet-wool o Criola correspondiente a la clasificación lanera oficial, por eso se considera necesario construir un mapa lanero Criollo de la República Argentina.

Purpose This paper aims to reflect on recent closed-loop supply chain (CLSC) practices using a natural resource-based view (NRBV) and dynamic capabilities (DC) perspective. Design/methodology/approach Two empirical case studies of CLSC exemplars are used to discuss the theoretical relevance of these views. Findings The paper shows how strategic resources help companies in two sectors achieve successful CLSC designs. Strategic supply chain collaboration is an important success factor but also presents a number of challenges. The NRBV is used to explain the importance of new resources in technology, knowledge and relationships and stresses the role of DCs to constantly address changes in the business environment to renew these strategic resources. Research limitations/implications This research elaborates on NRBV theory related to CLSCs and reinforces the inclusion of DCs. It specifies the application of NRBV in the context of textiles and carpet manufacture and highlights the inherent conflicts in seeking value while moving towards sustainable development. Practical implications Investments in technical and operational resources are required to create CLSCs. Pure closed-loop applications are impractical, requiring relationships with multiple external partners to obtain supply and demand for recycled products. Social implications CLSCs may provide opportunities for social enterprises or third sector organizations collaborating with manufacturers. Originality/value This paper provides insights into the constituent resources needed for successful CLSCs. It also helps move CLSC research from a tactical logistics problem to a problem of strategic resources and relational capabilities: what we term “dynamic supply chain execution”. This paper develops a framework for transitioning towards CLSCs, underlining the importance of co-development and forging new relationships through commitment to supply chain redesign, co-evolution with customers and suppliers and control of supply chain activities.

AbstractThe boreal forest consists of drier sunlit and moister-shaded habitats with varying moss abundance. Mosses control vascular plant–soil interactions, yet they all can also be altered by grazers. We determined how 2 decades of reindeer (Rangifer tarandus) exclusion affect feather moss (Pleurozium schreberi) depth, and the accompanying soil N dynamics (total and dissolvable inorganic N, δ15N), plant foliar N, and stable isotopes (δ15N, δ13C) in two contrasting habitats of an oligotrophic Scots pine forest. The study species were pine seedling (Pinus sylvestris L.), bilberry (Vaccinium myrtillus L.), lingonberry (V. vitis-idaea L.), and feather moss. Moss carpet was deeper in shaded than sunlit habitats and increased with grazer exclusion. Humus N content increased in the shade as did humus δ15N, which also increased due to exclusion in the sunlit habitats. Exclusion increased inorganic N concentration in the mineral soil. These soil responses were correlated with moss depth. Foliar chemistry varied due to habitat depending on species identity. Pine seedlings showed higher foliar N content and lower foliar δ15N in the shaded than in the sunlit habitats, while bilberry had both higher foliar N and δ15N in the shade. Thus, foliar δ15N values of co-existing species diverged in the shade indicating enhanced N partitioning. We conclude that despite strong grazing-induced shifts in mosses and subtler shifts in soil N, the N dynamics of vascular vegetation remain unchanged. These indicate that plant–soil interactions are resistant to shifts in grazing intensity, a pattern that appears to be common across boreal oligotrophic forests.

Streszczenie:

The inhuman acts of mass-killing and oppression are as old as the history of civilization. Many have been condemned while numerous still fail to make it to headlines. The very discrimination between what is condemned and what gets brushed under the carpet delineates an oppressive tendency based on factors such as race, ethnicity, caste and religion. The present paper aims to explore and interpret two episodes from the Mahabharata that deal with oppression and/or genocide. First is the popular episode of Sarpasatra where Janmejaya, son of Parikshit, embarks on the sarpamedha yajna to kill all the snakes in order to avenge the death of his father. The second is a lesser-known episode in the Astika Parva of the Mahabharta where Garuda, instructed by her mother Vinata, selectively eats thousands of nishada to quell his hunger. At the heart of both the episodes are discrimination, dehumanization and an act of othering. Janmejaya sees the nagas as a threat and feels their annihilation is justified. When Vinata is telling his son Garuda about the dwelling place of the nishada, her conscience is convinced, her morality justifies the mass-murder of a race that was considered inferior in the social structure. Her warning to his son regarding how to avoid any sin by eating not eating a brahmin confirms that the prevalent morality sanctioned/endorsed this oppression favoring the oppressor against the oppressed. The Mahabharata as a grand-narrative not only subtly points out the inherent oppressive nature of the patriarchal morality, but also comes up with counter-narratives. There is a twist in the tale. A brahmin married to a nishada comes to the rescue of his wife pointing out the existence of alternate moralities as well as the intermingling of races. Similarly, the sarpamedhha yagna is intervened by Astika and the race of snakes is spared. While the emergence of a rescuer marks a major turning point and an effort in bringing home the lesson of inclusiveness and harmonious co-existence, it does not undo the damages already caused in the process.

This article examines the possibilities of visual culture to open new perspectives on interspecies relations by analyzing self-portraits from visual artist Elina Brotherus’s photography series Carpe Fucking Diem (2011–2015). Brotherus has suggested that this series talks “about a failure to have a family with kids and give normality the finger”. The self-portraits can be seen to address this “failure” to have a normative nuclear family, while simultaneously questioning the desirability of the norm itself through Brotherus’s relationship with her pet dog, dachshund Marcello. The article explores the more-than-human notions of kinship and family in Carpe Fucking Diem, drawing on Donna Haraway’s concept of companion species, as well as discussions on new materialism and posthumanism. The concept of companion species deconstructs human exceptionalism and the boundaries between human and animal, and indicates that the physical and affective co-becomings between humans and the non-human significant others co-evolve with each other in complex and asymmetrical ways. In affective and embodied readings of three self-portraits and one video work from the Carpe Fucking Diem series, I examine how Elina Brotherus’s self-portraits call into question the normative notions of family as human-centered and heteronormative.

Streszczenie:

O carbeto cementado WC-Co também denominado de metal duro é um material de grande importância tecnológica produzido por metalurgia do pó através de sinterização por fase líquida, partindo-se da mistura dos pós de carbeto de tungstênio (WC) e de cobalto (Co) em moinho convencional. Entretanto, para obtenção de metal duro com maior capacidade (produtividade, vida útil, etc.), uma nova rota alternativa de metalurgia do pó denominada de altas pressões e altas temperaturas vem sendo utilizada para produção destes materiais com resultados promissores. O presente trabalho tem como objetivo principal a análise de fases de WC-10Co dopado com terras-raras (La2O3, CeO2e Y2O3) preparadas sob condições de alta pressão. Esta liga de metal duro é um exemplo de material compósito largamente utilizado como ferramenta de corte e operações de usinagem em geral. Foram preparadas diversas misturas de WC-10Co contendo até 2 % em peso de terra-rara (La2O3, CeO2e Y2O3) da fase cobalto. Os pós previamente misturados foram compactados numa matriz cilíndrica (Φ = 7 mm) a uma pressão de 800 MPa e sinterizados a 1400 ºC durante 40 s sob alta pressão de 5,5 GPa. Os compósitos produzidos foram caracterizados por difração de raios X para identificação de fases cristalinas presentes. Além disso, foi feita análise comparativa entre o carbeto isento de terra-rara (amostras de referência) e carbetos dopados com elementos de terra-rara (La2O3, CeO2, e Y2O3). Para as condições estudadas os resultados mostraram que durante o processo de sinterização ocorreu à formação, mesmo que em pequenas quantidades, das fases Co3W3C2 e γ (carbeto tipo ε) nas peças de metal duro estudadas.

Cette article examinera l'évolution récente du cahier de metteur en scène ou Regiebuch. Le cahier de mise en scène est l'instrument préféré du metteur en scène, ou « l'auteur » théâtral qui s'est développé le long du dramaturge depuis le début du XXe siècle. Traditionnelement le cahier se situe littéralement entre le texte dramatique et la mise en scène. C'est le carnet de croquis du réalisateur qui enregistre ses idées, ses intentions, ses rêves autour d'une production. En même temps, c'est aussi un journal du processus de répétition. Dans les développements du siècle dernier, souvent regroupés comme l'évolution vers un « théâtre des metteur en scènes » (plutôt qu'un théâtre de dramaturges), l'importance du Regiebuch a augmenté de façon spectaculaire. Dans l'histoire de la scène moderne, le texte devient moins important ou même disparaît au profit de l'imaginaire visuel et auditif du réalisateur. Avec l'émergence de nouveaux médias, tels que les enregistrements numériques et les applications informatiques pour l'édition audio et vidéo, la médialité du Regiebuch évolue également. De son statut initial de carnet de croquis et de journal, il se transforme en une sorte de « storyboard ». L'hypothèse de cet article est que la structure narrative, ou plutôt le récit visuel sur scène, est co-dirigé et déterminé par les techniques de composition visuelle utilisées pendant le processus de répétition. Afin d'élaborer et de tester cette théorie, les carnets de Jan Fabre et Romeo Castellucci seront discutés.

Abstract Chimeric antigen receptor (CAR) T cells have shown clinical efficacy in refractory B cell malignancies. Despite these exciting clinical results, our fundamental understanding of CAR-T cell biology is limited, possibly limiting the broader application of CAR-T cells to additional haemopoetic and solid cancers. To date, the mechanism of CAR-T immunological synapse formation with tumor cells and kinetics of subsequent serial killing by CAR-T cells has not been explored. Here, we investigated the kinetics of CAR-T cell activation and cytotoxicity, including immune synapse formation, and kinetics of tumor cell killing, closely comparing to activation and cytotoxicity via the T cell receptor (TCR). To address this, we developed a mouse model in which the CD8+ T cells (termed CAR.OT-I cells) co-expressed two antigen receptors, the clonogenic OT-I TCR, and a second generation CAR comprising a scFV to human HER2, CD28 and CD3ζ signaling domains. Effector CAR.OT-I cells were activated via their antigen receptors using either SIINFEKL-pulsed or HER-2 expressing tumor cells, the interactions between the effector CAR.OT-I cells and tumor cells were then assessed by time lapse live microscopy. CAR.OT-I cell activation via the endogenous TCR or the CAR did not affect tumor killing kinetics, except the time taken from CAR.OT-I activation to detachment (from the dying tumor cell) was significantly slower when the endogenous TCR was engaged. Subsequently, we showed for the first time, that CAR.OT-I cells have serial killing capacity, which is important to consider when therapeutic numbers of CAR-T cells are likely to be outnumbered by tumor targets. Individual CAR.OT-I cells killed multiple tumor cells, whether activated via the endogenous TCR or the CAR. We further explored whether these findings have implications for killing of tumor cells using low effector:target cell ratio in short versus long-term killing assays, chromium release and xCELLigence killing assays respectively. We observed, no matter which antigen receptor was activated, the effector CAR.OT-I cells were equivalent killers of tumor cells in short term assays (4-8 hours). However, over a period of 50 hours, CAR.OT-I cells activated via the CAR killed tumor cells at a lower rate than when activated via the TCR. This was due to CAR.OT-I CAR expression down-regulation from 20-50 hours. This study highlights that fundamental differences occur in the way CAR-T cells kill tumor cells, depending on how the effector CAR-T cell is activated. Furthermore, the study provides important insights for CAR-T cell activation in vivo with implications for single- or dual-receptor-focused CAR-T cell therapy and improved clinical benefit.

This paper highlights the authorship, co-authorship, and peer review experience of Ukrainian early career scientists to see their attitudes to scholarly communication. A questionnaire was distributed through Facebook groups and university networks all over Ukraine. Results from 630 respondents demonstrated contradictory tendencies of Ukrainian early scientists’ publication activity. Most respondents try to gain recognition, adhere to high standards, and improve their writing skills. Meanwhile, there is a problem of low motivation, violations of academic integrity, detachment from the international scientific community, etc. 5.6% of respondents admitted that they wrote articles where they substituted the results without conducting experiments, deliberately distorted the results of research, and forged experimental data. Above a half of the respondents (52.9%) have experience of reviewing and consider it to improve their authorship skills, engage in scientific dialogue, cope with new methods and theories, etc. But 95.0% of reviewers had problems, for example obviously poor-quality articles for review (47.5%), a request for a review when the article does not match the reviewer’s qualifications (32.5%), no access to data to check dubious results (15.0%), lack of instructions for reviewers (10.0%), ignoring significant remarks by authors (7.5%). The survey showed a significant predominance of co-authored articles. Among the main motives for publishing co-authored articles, respondents highlighted the following: saving time, intellectual development, co-payment of publications, access to expensive equipment, the chance of being quoted, and cooperation.

AbstractSynthesis, structure and reactions of technetium and rhenium complexes bearing metal-carbon multiple bonds are reported. Addition of LiPh to Cp*M (CO)3 (1a : M = Tc; 1b: M = Re) (Cp* = η5-C5Me5) in Et2O yields the acyl complexes Li[Cp*(CO)2MC(O)Ph]·Et2O (2a: M = Tc; 2 b: M = Re). These are converted with Et3OBF4 into the carbene complexes Cp*(CO)2M = C(OEt)Ph (3a, 3b). Reaction of 3a and 3 b with BCl3 affords the carbyne complexes [Cp*(CO)2M ≡ CPh]BCl4 (4a, 4b) in high yield. The acyl complex 2b can be directly converted into the carbyne complex [Cp*(CO)2Re ≡ CPh]Br (5b), when it is treated with oxalyl bromide. Nucleophiles add at the carbynecarbon atoms of 4a and 4b, as demonstrated by the reaction with NaOCy (Cy = cyclohexyl) to afford the carbene complexes Cp*(CO)2M = C(OCy)Ph (6a, 6b). Similarly, reaction of P(OMe)3 with [Cp*(CO)2Re ≡ CPh]Cl (5b'), the latter being generated in situ from 2b and oxalyl chloride, gives the ylide complex {Cp*(CO)2Re = C[P(OMe)3]Ph}Cl (7b'). In comparison, addition of P(OMe)3 to [Cp*(CO)2Tc ≡ CPh]Cl (5a'), generated in situ from 2a and oxalyl chloride, induces a carbvne-carbonvl coupling reaction resulting in the formation of the ketenyl complex . Thermolysis of the compounds 2a, 2b, 4a, 4b and 7b' has been studied in vacuo and the products of decomposition identified by IR spectroscopy. The solid-state structure of the carbene complexes 3 a and 3 b was determined by single crystal X-ray diffraction studies. Both compounds crystallize in the monoclinic space group P21/n with very similar unit cell data. Striking feature of the isostructural carbene complexes is the nearly perpendicular orientation of the carbene ligand relative to the Cp* ring.

The effect of modified atmosphere packaging (MAP 1 – 80% O<sub>2</sub> + 20% CO<sub>2</sub> and MAP 2 – 90% CO<sub>2</sub> + 10% N<sub>2</sub>) on selected chemical and sensory parameters of common carp steaks stored at 3 ± 0.5°C, and determination of the shelf life of the products was studied in this research. Samples were analysed on day 1, 3, 5, 7, 9, 11, 13, 15, and 17. An increase in TVB-N values in carp steaks followed the order: MAP 2 < control < MAP 1. From day 9 of storage FFA concentrations were higher (P < 0.01) in MAP 2 samples compared to control and MAP 1 samples. The presence of oxygen (MAP 1 and control) resulted in an increase in TBA values in comparison with samples packaged in the absence of oxygen. According to sensory evaluation, it was concluded that carp steaks packaged in modified atmosphere with 80% O<sub>2</sub> + 20% CO<sub>2</sub> remained acceptable up to 15 days of storage, whereas samples packaged under 90% CO<sub>2</sub> + 10% N<sub>2</sub> as well as samples kept on flaked ice remained unchanged until the end of the experiment.

Streszczenie:

With the recent research on the importance of the Estates, whose function often went far beyond questions of taxation, the Imperial Circles and the simultaneous deconstruction of European state formation as an absolutist top-down process the view of the “co-organizing intermediate levels” changed. This is how Johannes Burkhardt described these regional images in 2006 in “Gebhardt. Handbuch der Deutschen Geschichte.” The new view of the Old Empire has been well received by research in regional history, especially since differentiations on small-scale rule and organization in Bavaria, Baden-Württemberg, Hesse, Thuringia, Saxony and other federal states have traditionally been and still are part of the core business of this discipline. “Flickenteppiche” as colourfully woven objects of diversity are certainly still products in demand in the textile industry and consumer society, but they are just as unsuitable as an explanatory model for the coherence of the Empire and its Imperial Circles as they are for analyzing power and rule in the early modern period. In their figurative meaning of the word, patchwork carpets ignore communicative processes for decision-making just as much as they register cross-border action and design as a quantité négligeable.

Crop male sterility has great value in theoretical research and breeding application. HTS-1, whose stamens transformed into pistils or pistil-like structures, is an important male sterility material selecting from Chinese Spring three-pistil (CSTP) wheat. However the molecular mechanism of pistillody development in HTS-1 remains a mystery. RNA-seq data of 11 wheat tissues were obtained from the National Center for Biotechnology Information (NCBI), including the stamens of CSTP and the pistils and pistillodic stamen of HTS-1. The Salmon program was utilized to quantify the gene expression levels of the 11 wheat tissues; and gene quantification results were normalized by transcripts per million (TPM). In total, 58,576 genes were used to construct block-wise network by co-expression networks analysis (WGCNA) R package. We obtained all of modules significantly associated with the 11 wheat tissues. AgriGO V2.0 was used to do Gene Ontology (GO) enrichment analysis; and genes and transcription factors (TFs) in these significant modules about wheat pistillody development were identified from GO enrichment results. Basic local alignment search tool (BLAST) was used to align HTS-1 proteins with the published pistillody-related proteins and TFs. Genes about wheat pistillody development were analyzed and validated by qRT-PCR. The MEturquoise, MEsaddlebrown, MEplum, MEcoral1, MElightsteelblue1, and MEdarkslateblue modules were significantly corelated to pistillodic stamen (correlation p < 0.05). Moreover, 206 genes related to carpel development (GO:0048440) or gynoecium development (GO:0048467) were identified only in the MEturquoise module by Gene Ontology (GO) analysis, and 42 of 206 genes were hub genes in MEturquoise module. qRT-PCR results showed that 38 of the 42 hub genes had highly expressed in pistils and pistillodic stamens than in stamens. A total of 15 pistillody development-related proteins were validated by BLAST. Transcription factors (TFs) were also analyzed in the MEturquoise module, and 618 TFs were identified. In total, 56 TFs from 11 families were considered to regulate the development of pistillodic stamen. The co-expression network showed that six of HB and three of BES1 genes were identified in 42 hub genes. This indicated that TFs played important roles in wheat pistillody development. In addition, there were 11 of ethylene-related genes connected with TFs or hub genes, suggesting the important roles of ethylene-related genes in pistillody development. These results provide important insights into the molecular interactions underlying pistillody development.

Streszczenie:

O método convencional de sinterização do carbeto de silício (SiC) apresenta custos consideravelmente inviáveis, uma vez que demanda a aplicação de elevadas temperaturas e uso de atmosfera inerte. Portanto, uma abordagem alternativa de sinterização foi estudada, utilizando fornos com temperaturas abaixo de 1700°C e atmosfera oxidante. Com isso, foram fabricados 3 tipos de amostras com as seguintes composições: SiC puro, SiC com Alumina e SiC com Ítria, todos produzidos com ligante base de álcool polivinílico líquido (PVA). Os corpos de prova foram submetidos a uma pré-carga de 0,5 toneladas para o tempo de um minuto e, posteriormente, aplicou-se 4,0 toneladas pelo mesmo período. Cinco corpos de prova foram fabricados para cada tipo de composição. Duas estratégias de processamentos foram usadas para comparação. O processo A consistiu na retirada do ligante com pré-sinterização até 1100°C seguida da sinterização até 1900°C sob atmosfera inerte. O processo B também envolveu a retirada do ligante com pré-sinterização até 1100°C seguida da sinterização até 1400°C sob atmosfera oxidante. As análises das composições foram conduzidas através dos testes de Microscopia Eletrônica de Varredura (MEV), Difração de raios X (DRX) e Análise Termogravimétrica (TGA). O difratograma revelou que as fases cristalinas de Al2O3 e Y2O3 não apresentaram impurezas. No entanto, o SiC manifestou divergências em relação à pureza informada pelo fabricante. O TGA do SiC puro mostrou um ganho de massa pouco expressivo à 900°C, devido à oxidação em algumas amostras, e perda de massa devido à reação do SiC com o SiO2 resultando na formação do produto gasoso CO. Para os resultados de TGA do SiC puro, SiC+Al2O3 e SiC+Y2O3, observou-se um leve aumento de massa nas duas últimas composições e um aumento mais significativo no primeiro ao atingir a temperatura de 1500°C, o que pode ser atribuído à oxidação do SiC.
