Autor skupił się na interakcyjnych technikach (zarówno formalnych, jak i nieformalnych) wykorzystywanych przez marszałków w celu skutecznego przeprowadzenia obrad sejmowych. Celem artykułu jest analiza środków, jakie może zastosować marszałek, aby emocje nie zakłóciły procesu decyzyjnego ciała ustawodawczego.This paper analyzes actions taken by the Marshals of the Polish Parliament to control the emotions that appear in the parliamentary hall during the meeting and debates.

Effects of post-mortem time before chilling and chilling temperatures on water-holding capacity and texture of turkey breast muscle
No full textTwo studies were conducted to determine 1) the effect of post-mortem time before chilling on hot boned prerigor breast muscle water-holding capacity (WHC), and 2) post-mortem temperature effect on sarcomere length and drip loss of uncooked breast, and shear force and WHC of turkey breast muscle that is hot-boned, marinated, and cooked. In Study 1, the turkey breast muscle was excised immediately after slaughter and chilled at 0 C. The effect of post-mortem time (15, 30, 45, 60, 90, and 120 min) before chilling on muscle pH, drip loss, and WHC (measured by homogenate cooking yield) was determined. In Study 2, hot boned prerigor breast slices were held at either 0 or 12 C and then at 3 h post-mortem stored at 2 C. Sarcomere length and drip loss of uncooked breast, and the shear force and WHC (measured by cooking yield) of cooked breast muscles with water, salt, and sodium tripolyphosphate were determined. Results indicated that pH on Day 1 post-mortem and cooking yield of water homogenates were not influenced by the post-mortem time before chilling. Drip losses increased as the post-mortem time before chilling was increased. Cooking yield of homogenate with water, salt, and sodium tripolyphosphate was decreased when breast muscle was chilled after 60 min post-mortem. Drip loss of breast was less at 0 C than at 12 C, but cooking yield and shear force were not affected by post-mortem chilling temperature. It was concluded that the post-mortem time before chilling has an influence on uncooked and cooked muscle WHC, but the differences found in uncooked muscle drip loss were not reflected in WHC or shear force of cooked muscle with water, salt, and sodium tripolyphosphate added.This article is published as Lesiak, M.

Nuclear magnetic resonance structure of d(GCATATGATAG)·d(CTATCATATGC): A consensus sequence for promoters recognized by s(K) RNA polymerase
No full textThe three-dimensional structure of d(GCATATGATAG)·d(CTATCATATGC), from the promoter region of a gene regulating sporulation in Bacillus subtilis mother cells, was determined utilizing two-dimensional nuclear Overhauser effect (2D NOE) and double-quantum-filtered COSY (2QF-COSY) spectra. To minimize the effect of methods used to obtain restraints and refine structure, several variables were studied. Interproton distance bounds were calculated very conservatively by running the complete relaxation matrix program MARDIGRAS hundreds of times using 2D NOE spectra for exchangeable and for nonexchangeable protons at different mixing times, assuming different overall correlation times and different starting structures. The 435 distance restraints were used with two different structural refinement methods: restrained molecular dynamics (rMD) and restrained Monte Carlo calculations (rMC). Refinement using different procedures and starting structures resulted in essentially the same structure (<0.8 Å rmsd), indicating that the structure is defined by experimental restraints and not the refinement method or variables used. R factors indicate the structures fit the experimental NOE data very well. Some helical parameters, notably large negative X displacement, are characteristic of A-DNA, but others are characteristic of B-DNA. As with TG·CA steps in other duplex DNA sequences studied in our laboratory, the two TG·CA steps have a positive roll, with T6-G7 exhibiting the largest, and consequently a bent helix axis. The converged structure represents a time-averaged structure. However, multiple conformations, especially in deoxyriboses, were evident from vicinal coupling constants obtained from quantitative simulations of 2QF-COSY cross-peaks and from persistent inconsistencies in experimental distances due to nonlinear conformational averaging
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

Film wojenny w perspektywie genologicznej
No full textWar film in genological perspective
This article aims to present basic problems, that are related to war film as a film genre. The author examines popular theories on the extent and distribution of the war film category. For this purpose he reaches to the works of Jeanine Basinger, Łukasz Plesnar and Steve Neale. The article points out the controversies caused by narrow definition of the discussed notion.
