Abstract:

We have produced three dimensional reconstructions of several regions of the Z band and the nearby I band in rat soleus muscle in rigor. The reconstructions were calculated using weighted back-projection techniques on electron micrograph tilt series taken about two orthogonal axes. Examination of cross-sections of the reconstructed Z bands reveal that the lattice is in the basket-weave form. We have previously shown that this form of the Z band lattice predominates in the muscle in rigor. The reconstructions reveal a dense net of cross-connecting Z-filaments in the Z band, which interconnect the axial filaments in a projected four-fold array.The Z band lattice spacing was measured as 27 +− 4 nm, consistent with values seen in electron micrographs of cross sections of this muscle. The Z spacing and the form of the lattice show little distortion from that observed in cross sections, despite a beam induced change in section thickness from ∼80 to 45 nm. This suggests that, as in previous Z band reconstructions in unstimulated muscle, section shrinkage in the Z band does not occur by means of a uniform collapse throughout the section.

Abstract:

The total photoelectric cross-sections in the elements gadolinium, dysprosium, erbium, lutetium, tantalum, tungsten, gold, and lead have been obtained by using the normal transmission experiments, and the results are reported. Using these total photoelectric cross sections, we have found the K-shell photoelectric cross sections, the K-jump ratios, and the total-to-K-shell photoelectric cross-section ratios at the K edges for the above elements. These values are compared with the available theoretical and experimental values. The results are in good agreement with the Storm and Israel results and the Scofield theoretical values, within the limits of experimental uncertainties. Furthermore, the variation of the total-to-K-shell photoelectric cross-section ratio with energy and atomic number is discussed.

Abstract:

Generation Z is gaining popularity as the name used to refer to those born beginning in the mid to late 1990s. This is the generation that follows the Millennials, and they are just starting to arrive on college campuses. Much attention has been paid to Millennials and their impact on society, and because of this Generation Z members are often lumped together with this older cohort. But Generation Z students are unique, and universities and colleges must prepare to meet the challenges of instructing this new generation. Engineering educators in particular are being challenged to adapt to the speed of technological change. Faculty must consider how to adjust to this new environment, including the changing needs and expectations of Generation Z students. This paper explores these topics. The first section will explore the concept of a generation and describe some of the attributes associated with Generation Z. The second section will review the development of engineering education in the United States and some of the major reforms that have occurred in the past 100 years. The last section will discuss potential changes in the classroom to try and address some of the characteristics of Generation Z students.

Abstract:

AbstractThe article presents comparative analyzes aimed at determining the optimal cross-section used in cold-formed steel purlins. The geometrical characteristics, bending resistance and self-weight of channel, zeta and hat cross-sections were compared. The calculations were made using Dlubal SHAPE-THIN software for the bending by the main axis y-y and z-z. The characteristics for the gross and effective cross-section were determined. Based on the first stage analyzes, a significant decrease in cross-sectional bending resistant was observed as a result of a local buckling. The solution to this problem may be the use of intermediate stiffeners. In the second stage, analysis of the impact of the intermediate stiffeners’ locations on the characteristics of hat sections were conducted. Additional intermediate stiffeners on the webs, on the upper chord, and on the webs and upper chord (together) were considered. A significant effect on the bending resistant with a small increase in the element’s self-weight has been demonstrated. In the third stage, the characteristics of a channel, zeta and hat profile with intermediate longitudinal stiffener in the middle of the web were compared. The performed analyzes demonstrated that the hat cross-section shows a significant advantage in bending by the main axis z-z. This advantage can be used in case of lack of protection against lateral torsional buckling and a larger degree of roof slope.

Abstract:

AbstractA simple parameterization is presented for the elastic electron scattering cross sections from single atoms into the annular dark-field (ADF) detector of a scanning transmission electron microscope (STEM). The dependence on atomic number, Z, and inner reciprocal radius of the annular detector, q0, of the cross section σ(Z,q0) is expressed by the empirical relationwhere A(q0) is the cross section for hydrogen (Z = 1), and the detector is assumed to have a large outer reciprocal radius. Using electron elastic scattering factors determined from relativistic Hartree-Fock simulations of the atomic electron charge density, values of the exponent n(Z,q0) are tabulated as a function of Z and q0, for STEM probe sizes of 1.0 and 2.0 Å.Comparison with recently published experimental data for single-atom scattering [Krivanek et al. (2010). Nature464, 571–574] suggests that experimentally measured exponent values are systematically lower than the values predicted for elastic scattering from low-Z atoms. It is proposed that this discrepancy arises from the inelastic scattering contribution to the ADF signal. A simple expression is proposed that corrects the exponent n(Z,q0) for inelastic scattering into the annular detector.

Abstract:

AbstractPrevious studies of vetch species belonging to sections Hypechusa, Narbonensis and Peregrinae have revealed controversies and open questions that deserve revisiting with the use of contemporary approaches. The paper extends the previous work of Leht and Jaaska (2002) by describing variation of 16 isozymes and 86 morphological characters among 17 Vicia species belonging to sections Hypechusa, Narbonensis and Peregrinae of the type subgenus in comparison with V. bithynica of section Pseudolathyrus. Three more isozymes and 12 new morphological characters are included to improve the resolution of phylogenetic relationships. The maximum parsimony trees based on isozymes and morphology revealed essentially the same four clusters of species that correspond to series Hypechusa and Hyrcanicae of section Hypechusa, to sections Narbonensis and Peregrinae of current taxonomy, except that the isozyme tree placed V. lutea of series Hypechusa into a separate clade. Isozyme variation in V. mollis, V. noeana, V. sericocarpa and V. ciliatula of section Hypechusa is described for the first time. Twenty-three species-specific isozymes that may be used for species identification by analysis of seeds are described. Two new isozymes that distinguish V. serratifolia from V. narbonensis are described that further support their specific status. Series Hypechusa and Hyrcanicae of section Hypechusa, sections Narbonensis and Peregrinae of traditional taxonomy are monophyletic groups that deserve sectional status within the genus Vicia. The phylogenetic position and sectional placement of V. lutea warrants further study with independent sets of DNA characters.

The results include the measurement of the single W and Z boson cross section at LHC, the differential cross section measurements, the measurement of W boson mass, the measurement of W and Z charge asymmetry. These measurements provide precision tests on the electroweak theory, high order predictions and the information can be used to constraint parton distribution functions.

Abstract:

Making use of the numerical analysis method, the ductility of reinforced concrete column with Z-shaped cross-section was analyzed. Considering stirrup confinements’ influence upon concrete deformation, with using self-made programs, some elements imposing influence on column section ductility were analyzed, such as axial compressive ratio、loading angle、material strength and setting mode of reinforcing bars. The results indicates that the loading angle has great influence on section especially under smaller compressive ratio, while the strength changes of the concrete and reinforced bars has a little influence. Thus, without changing amount of steel, encrypted hooping will effectively improve the ductility of column section.

Abstract:

The A-dependence of z-scaling in inclusive hadron production in pA collisions at high transverse momenta is studied. The concept of z-scaling based on the fundamental principles of Nature such as self-similarity, locality, scale relativity and fractality reflecting the general features of particle interactions is applied for the description of processes of hadron production in pA collisions. The scaling function ψ is expressed via the invariant cross-section Ed3σ/dq3 and the average multiplicity density dN/dη of particles produced at pseudorapidity η=0 in the corresponding nucleon–nucleon interaction. The independence of the function ψ(z) on the center-of-mass energy [Formula: see text] for particle production near 90° in the NN c.m. system for different nuclei from D up to Pb is shown. The scale transformation z→az, ψ→a-1ψ is used to determine the A-dependence of the transformation parameter a. Based on the properties of z-scaling the dependence of the cross-sections for the π±, K±, and [Formula: see text] hadrons produced in pA collisions on transverse momentum q⊥ in the central region (η=0) at RHIC energies is predicted.

Summary In this article, we formalize some basic facts of Z-module. In the first section, we discuss the rank of submodule of Z-module and its properties. Especially, we formally prove that the rank of any Z-module is equal to or more than that of its submodules, and vice versa, and that there exists a submodule with any given rank that satisfies the above condition. In the next section, we mention basic facts of linear transformations between two Z-modules. In this section, we define homomorphism between two Z-modules and deal with kernel and image of homomorphism. In the last section, we formally prove some basic facts about linearly independent subsets and linear combinations. These formalizations are based on [9](p.191-242), [23](p.117-172) and [2](p.17-35).

The result indicated that the ANSYS simulation value was closely with the experimental value and the formula predicted value, and the formula predicted value security, has the high reliability.

Abstract:

We have completed 3-d reconstructions of several regions of the Z-band in relaxed rat soleus muscle using the method of weighted back projection on a tilt series from two different longitudinal sections. Various displays of the reconstructions were interpreted after corrections for section shrinkage and comparisons to three dimensional models. Examination of cross-sections of the reconstructed Z-bands reveal that the lattice is in the small square form. We have previously shown that this form of the Z-band lattice is predominate in relaxed skeletal muscle. The reconstructions reveal that cross-connecting Z-filaments are arranged in opposing pairs along the axial filament. Successive pairs of filaments are rotated by ninety degrees about the axial filament, thus generating the four-fold appearance seen in the projected small square lattice.

Abstract:

In gas turbine blade design, a variety of channel shapes and orientations are used in the cooling circuit. Most of the rotating channel heat transfer research to date has considered channels of square or round cross-sections. This research characterizes the effect of rotation on fully developed turbulent convective heat transfer in ducts of narrow cross-section (height-to-width aspect ratio of 1:10). Experiments were conducted using ducts of narrow cross-section, oriented such that the long sides of the duct cross-section are perpendicular to the direction of blade tangential velocity (parallel to the r-z plane). In the experiment, a high-molecular-weight gas (Refrigerant-134A) at ambient pressure and temperature conditions was used to simulate coolant-to-wall density ratios that match engine conditions. Thin foil heaters were used to produce a uniform heat flux at the long sides of the duct; the narrow sides were unheated. Duct Reynolds numbers were varied up to 31,000; rotation numbers were varied up to 0.11. The test results show the effect of rotation and aspect ratio on duct leading and trailing side heat transfer. The results provide insight into the effect of rotation (Coriolis) in the absence of buoyancy effects. Comparisons with previously reported results are presented to show the effect of cross-section shape on rotating channel heat transfer.

Abstract:

The paper discusses Wittgenstein’s approaches to ethics within two contrastive contexts, e.g., pragmatism and cooperative-discursive normative practice. The first section revisits the fiasco of his early “negative” ethics. The second section subsequently shows how Wittgenstein’s mature concept of blind rule-following displaces normativity but simultaneously becomes the key predictor for discourse ethics (or, rather, a specific kind of it). The final section discusses the pros and cons of finitism in the light of contemporary philosophy of mind. As a conclusion, the author provides evidence for her hypothesis that there is no normative (embodied) mind without a manifest normative competence, which includes moral judgment and discursive competence.

Abstract:

Introduction to the Thematic SectionThe images of the borders of civilizations is the main topic of the thematic section of this issue of Colloquia Humanistica. In the call for papers it was emphasised, that this issue is particularly important, because the notion of civilization is strictly related to the issue of borders since it would became meaningless without the opposition to another civilization, or the lack of it. The juxtaposition between the notion of civilization and its different antinomies seems easier to display when seen from its centre, however the shape of its border is not always clear, even if it has a foundation in clear geographical or political divisions. Thus, this border can be represented as a linear frontier between a civilized state and barbaric lands, or as a borderland which encompasses some kind of fluent transition. The civilization border can be also represented in a macro scale, shaping geographic divisions of the continents (as it was in the case of the Balkans), but its depiction can also concern the micro scale, for example the difference between an urban and a natural landscape. The notion is even broader, because it is not only treated in the context of space but also social behaviours and their evolution (which is bound with notion of the progress since the Enlightenment). The question establishing the difference between the civilized and the uncivilized is still shaping the identity of modern societies, and thus it is worth attention. Wprowadzenie do sekcji tematycznejTematem przewodnim szóstego numeru rocznika Colloquia Humanistica są obrazy granic cywilizacji. Temat ten wydaje się niezwykle istotny, ponieważ pojęcie cywilizacji ściśle wiąże się z kategorią granicy, skoro traci ono znaczenie, gdy nie zachodzi opozycja wobec innej cywilizacji. Zestawienie pojęcia cywilizacji i jego różnych antynomii najłatwiej przejawia się, jak się wydaje, z perspektywy centrum, jednakże kształt jej granic nie zawsze rysuje się wyraźnie, nawet gdy wywodzi się ona z jasnych podziałów geograficznych czy politycznych. Granicę może zatem reprezentować linia między cywilizowanym państwem a krajami barbarzyńskimi lub też pogranicze, stanowiące coś w rodzaju płynnego przejścia. Granicę cywilizacji można też przedstawić w makroskali poprzez podziały geograficzne na kontynencie (jak ma to miejsce w przypadku Bałkanów), lecz jej obraz dotyka również mikroskali, na przykład różnicy między krajobrazem miejskim a naturalnym. Pojęcie to ma wręcz szerszy charakter, ponieważ porusza kontekst nie tylko przestrzenny, lecz również kwestię zachowań społecznych i ich ewolucję (od czasu oświecenia związaną z pojęciem postępu). Kwestia ustanowienia granicy między cywilizowanym a niecywilizowanym wciąż wpływa na kształt tożsamości współczesnych społeczeństw i dlatego warto podjąć się jej zbadania.

Abstract:

Inclusive jet production in [Formula: see text] and pp collisions at high energies in the framework of the concept of z-scaling is studied. The available experimental data on the cross-section of jet production obtained by the UA1, UA2, CDF and D0 Collaborations are used for analysis. The scaling function ψ(z) is expressed via inclusive cross-section Ed3σ/dq3 and jet multiplicity density ρ(s,η). The properties of z-scaling, the energy and angular independence of ψ(z) and the power behavior, ψ(z)~z-α, of jet and dijet production were found. Based on the properties of z-scaling, the dependence of the cross-section of jets produced in [Formula: see text] and pp collisions on transverse momentum q⊥ over the central range is predicted. The obtained results can be of interest for future experiments planned at RHIC, LHC, HERA and Tevatron to search for new phenomena in hadron–hadron, hadron–nucleus and nucleus–nucleus collisions.

Abstract:

The effective bearing length of trapezoidal sheeting on cold formed sections at inner supports is 10 mm according to EN 1999-1-4 (aluminium) and EN 1993-1-3 (steel). In the original design provisions the effective bearing length on Z-sections was the actual width of the loaded flange. In order to find out the appropriate effective bearing length, FEM calculations were made on simply supported beams with C-, Z-and Sigma-cross-section. Contact elements between the trough of the trapezoidal sheeting and the loaded flange of the beam made it possible to evaluate the contact area. This area and the stresses in the trapezoidal sheeting show that the effective bearing length is very small for C-sections. For Z-sections and for Sigma sections with large folds in the web the contact area is the flange width, unless the flange width versus profile height is large and the plate thickness is small.

Abstract:

Recent CMS results on diffraction are presented. These include the measurements of the soft diffractive cross sections, of the forward rapidity gap cross section, of the diffractive dijet cross section, the measurement of a large rapidity gap in W and Z boson events and the measurement of the pseudorapidity distribution of charged particles in a single diffractive enhanced sample. This last measurement is the first common result of the CMS and TOTEM collaborations. Some prospects of common CMS-TOTEM data taking are also discussed.

Abstract:

We discuss and contrast search limits for and properties of new Z′ gauge bosons which can be probed at high energy e+e− colliders within the context of several E6 superstring-inspired models. In particular, we discuss the probability of distinguishing these various models from one another and determining the Z′ coupling parameters uniquely. Using the deviations from the standard model predictions for asymmetries and cross sections for various final state fermions, we set discovery limits for new Z′ bosons at [Formula: see text] and 1 TeV e+e− colliders. We find quite generally that cross section deviations provide the strongest limits on the existence of new Z′ bosons below threshold even when 100% beam polarization is available. The possibility of using Z′ pair production as a sensitive probe of the e+e−Z′ coupling is also examined.

Abstract:

We investigate the feasibility of distinguishing among different models of electroweak symmetry breaking by studying the process γγ → Z L Z L at photon colliders. For models with a low mass Higgs-like scalar resonance, the s-channel contribution provides a distinct resonance structure and large cross-sections. However, the absence of a resonance structure in the cross-section for the above process does not discriminate in principle between the existence of either a heavy Higgs boson or a vector resonance of a nonlinearly realized symmetry.

Abstract:

The purpose of this work is to show the hidden effect of the first transport cross-section in the study of the beam electrons transport impinging in solid targets by using the Monte Carlo method. For this, our study is based on our model of differential elastic cross-section given [A. Bentabet, Z. Chaoui, A. Aydin and A. Azbouche, Vacuum85 (2010) 156] by leaving only one free parameter adjusted, on one hand, to the elastic total cross-section and to transport cross-section, on the other hand. We think that this work is useful for those who develop semi-empirical or analytical models of elastic cross-sections. The present work deals with the total elastic cross-section, the first transport cross-section, the diffusion polar angle and the backscattering coefficient, from low energy electrons, normally incident, impinging on Al , Si , Ag and Au solid targets, where the results are compared to those of the literature and discussed.

Abstract:

A number of superstring theories predict the existence of an extra new Z′-boson and leptoquarks which may possess massess about 1–10 TeV. We investigate in detail possible manifestations of these particles in polarized e+e− beams on future colliders LEP II and CLIC. We calculate cross-sections and various asymmetries of the processes e+e−→µ+µ−, [Formula: see text], ūu taking into account contributions of the Z′-boson and leptoquarks. It is shown that the measurement of the total cross-section σ(e+e−→µ+µ−) is the most sensitive parameter for the existence of Z′-bosons, and the forward-backward asymmetry AFB is that for the existence of leptoquarks.

Abstract:

Experimental results on measurement of dd-reaction cross sections in the energy range of 0.1–1.5 keV using the Z-pinch technique are presented. The experiment was fulfilled at the high current generator of the High-Current Electronics Institute, city of Tomsk, Russia. The dd-fusion neutrons were registered by time-of-flight scintillator detectors and BF3 detectors of thermal neutrons. The estimates were obtained at 90% of the confidence level for the upper limits of the neutron-producing dd-reaction cross sections for average deuteron collision energies of 0.11, 0.34, 0.37, and 1.46 keV. These results substantiate feasibility to get a cross section magnitude for dd-reaction in the range of the collision energy of 0.8–3 keV using similar technology at the pulse current level of 2–3 MA.

Abstract:

Settlement phases of the Białogard stronghold, excavated in the years 1970-1972, have been dated by pottery typology so far. These dates, in particular those from the earliest phases, have been recently questioned. Twelve wooden samples from well preserved wooden constructions from the sixth phase of the stronghold fortification were taken in 1991 from a section of the former trench. The following dates of truncation were obtained: 878-892 and 902/903 AD. Pottery chronology of the sixth phase gave 25 years older dates. There are still no precise dates from the earliest phases of occupation.
