Abstract:
The ‘selling arrangement’ is a judicial device which removes national law from thescrutiny of European Community law relating to the free movement of goods. National provisions affecting the marketing of products may fall for consideration as ‘selling arrangements’ where the treatment of the domestic and imported goods has been even handed. Measures relating to the substance of the goods remain subject to Community law rules on the free movement of goods. The prime example of the selling arrangement is the advertisement, but in the years since creation, other areas of national activity with respect to the free movement of goods have been enveloped inthe selling arrangement. Certain measures which have related to the conduct of business may also fall for similar treatment as selling arrangements. A recent development would appear tomean that the concept of the selling arrangement may apply where the obligation imposed by the national measure has beenidentified as being general, as opposed to specific in nature. Were this to be so, the selling arrangement would have the potential to break free of the traditional boundaries established for itunder Criminal Proceedings against Bernard Keck and Daniel Mithouard.1

Abstract:
Paul Wittgenstein's one-handedness has typically been framed as a physical limitation at odds with an able-bodied ideology driving musical performance. Contemporary reviews, for instance, frame the pianist's disability as a tragedy heroically transcended during the course of virtuosic performance; others suggest that Wittgenstein successfully "passed" as two-handed. A study of Wittgenstein's numerous one-hand arrangements reveals similar narratives: the pianist often attempted to imitate the sound of two-handed piano music, and many of his own keyboard exercises train his one hand to assume the load of two. The "deficiency" model can be seen most dramatically in three attempts to arrange Witt-genstein's commissions for left-hand piano into a more "normal" performance medium: Sergei Prokofiev's expressed (but abandoned) interest in arranging his left-hand piano concerto for piano two-hands, Alfred Cortot's completed draft of a two-hand arrangement of Ravel's Concerto pour la main gauche, and, most significantly, Friedrich Wührer's highly successful two-hand arrangements of Franz Schmidt's left-hand pieces for Wittgenstein, which explicitly adopt a program of "strengthening" and "filling in" the supposed weaknesses of a disabled performance medium. Yet, despite the stigma it may have accrued, one-handed pianism is but a more prominent, more public example of the "bodily limits" all performers must confront; similar discourse surrounds the deficiencies of small hands or stiff fingers, for example. For the performer's body must negotiate its corporeal finitude with the complex demands of the musical score. As seen here in the career of Wittgenstein, an aesthetics of disabled performance presents this dialectic in heightened microcosm.

Abstract:
A numerical investigation of incompressible flow about transversely oscillating cylinder pairs is performed. Both tandem and side-by-side arrangements undergoing both flow-induced and forced transverse oscillations are considered. A second-order projection scheme is used to solve the 2-D incompressible Navier Stokes equations and a staggered approach is used to couple flow and structural response. Automatic mesh deformation and adaptation are used to handle arbitrary motion of the bodies. Comparisons with experimental results indicate that the present numerical method can capture complex interference and flow–structure interaction phenomena. Specifically, results are presented that demonstrate wake galloping effects, in which a cylinder in the wake of another experiences large flow-induced vibration over a wide range of flow velocities, and the presence of an experimentally observed secondary peak in the flow-induced vibration of rigidly connected cylinders in a tandem arrangement. An explanation of this secondary peak is provided by employing appropriate visualization of the unsteady flow. Results for forced oscillation of a pair of cylinders in a side-by-side arrangement are also presented that show the effect of phase angle on the wake structure behind the cylinder pair.

Abstract:
This study examined the stimulus-response stereotypes of American (United States citizens) and Japanese (Japanese citizens) subjects on the issue of control-display arrangements. Three questions were investigated. First, do Japanese and Americans operators adhere to the same compatibility principles, e.g., clockwise-for-increase, for certain configurations? Second, do the operators show similar or different responses to certain configurations? Third, are there arrangements in which both populations show strong or weak stimulus-response stereotypes? A paper and pencil test that contained 24 different control-display configurations was administered to 58 American subjects and 58 Japanese subjects, all of whom were right-handed. Out of the 24 configurations, only one elicited similar and statistically significant response stereotypes from American and Japanese subjects. The arrangement that did so emphasized that three compatibility principles (clockwise-for-increase, nearness of control-cursor relation, and scale-side) be in agreement with each other. The results provide initial, albeit speculative, guidelines for the design of control-display systems in NASA's international space station. Since multicultural crews will inhabit the space station for long duration missions, control-display designs which elicit common, consistent, and extremely strong control-movement stereotypes from different cultural populations is a necessity.

Abstract:
Abstract The diffracted intensity of an x-ray or neutron diffraction experiment is expressed as an integral over an atomic position distribution function. A generalized Debye scattering formula results. Since this distribution function is expanded into a series of spherical harmonics, an inverse Hankel transform of the intensity allows the calculation of the expansion coefficients which describe the atomic arrangement completely. The connections between the generalized Debye scattering formula and the original Debye formula as well as the Laue scattering formula are derived.

Abstract:
Weak governance is a major threat to sustainable development, especially in rural contexts and within ecosystems of great social and economic value. To understand and compare its arrangement in the grasslands and wetlands of the Colombian Llanos and the Paraguayan Pantanal, we build upon the Institutional and Development Framework (IAD) as we explore the role of political, economic, and social institutions and combine components of the theory of common-pool resources (CPR) and new institutional economics (NIE). This hybrid conceptualization provides a synthesis of how top-down hierarchical and market-based systems of community-based and natural resource management negatively affect sustainable development in both study areas. Our findings suggest three underlying mechanisms causing a situation of weak governance: centralized (economic and political) power, the role of central and local governments, and social exclusion. Understanding these multidimensional contextual mechanisms improves the understanding that institutional structures supporting arrangements that handle grasslands and wetlands in a sustainable way are needed to protect the ecosystem’s social and economic values, especially in rural and marginalized contexts.

Abstract:
AbstractThe Dutch West India Company (WIC), founded in 1621, was, in the words of the States General, “disbanded and destroyed” in September 1674 due to bankruptcy. In its stead, a second West India Company was founded, with a charter largely taken over from the first. This article explores how the dissolution of the first company and the conflicting interests of stockholders, bondholders, and company directors were managed. As it turns out, the old company was not actually liquidated; instead, its assets were simply handed over to the successor company, while an intricate financial construction was devised to take care of the debt burden and to capitalize the new company. The reasons for this unusual arrangement must be sought in the company's great political, and particularly geopolitical, importance. Since the Dutch state was unwilling and unable to handle colonial governance and defence itself, it needed a placeholder in the form of a chartered company. However, the bankruptcy of the WIC, coming at the time it did, had major consequences for the shape of the Dutch Atlantic of the eighteenth century.

Abstract:
When reservations are made to for instance a train, it is an on-line problem to accept or reject, i.e., decide if a person can be fitted in given all earlier reservations. However, determining a seating arrangement, implying that it is safe to accept, is an off-line problem with the earlier reservations and the current one as input. We develop algorithms with optimal running time to handle problems of this nature.

Abstract:
Considering the influence of different-shaped pans on space utilization and heat distribution, two models are established to investigate a balanced solution. In order to handle the problem of heat distribution on the outer edge, the first model establishes differential equations of heat convection in unstable state and gets definite conditions. Then we discretize the area of pans and get numerical solution by finite difference method. Having analyzed the numerical solution, our model finally concludes that the temperature field of a regular polygon can be regarded as a series of circles centering at its circumcenter and the temperature increases with the increment of the radius. As for the second model, we first calculate the maximum value of pans N in the oven by the arrangements of aligned and staggered modes. Then we normalize N by min-max method. Next, based on the rule of temperature field in the first model, the uniformity of heat distribution can be measured by the area ratio of a regular polygon to its circumcircle. After that, we use the linear weighted method to transfer the problem of multi-objective optimization into a single-objective one and draw the conclusions below: In aligned arrangement, we select round pans when p<0.3, rectangular pans when and pans in regular octagons when . In staggered arrangement, we select round pans when the value of p is small and pans in regular hexagons when the value of p is large. Eventually, through sensitivity analysis , our model proves to be stable and applicable.

Abstract:
In this paper, we demonstrate a method of designing all-dielectric metamaterial frequency selective surface (FSS) with ceramic resonators in spatial arrangement. Compared with the traditional way, spatial arrangement provides a flexible way to handle the permutation and combination of different ceramic resonators. With this method, the resonance response can be adjusted easily to achieve pass/stop band effects. As an example, a stop band spatial arrangement all-dielectric metamaterial FSS is designed. Its working band is in 11.65–12.23[Formula: see text]GHz. By adjusting permittivity and geometrical parameters of ceramic resonators, we can easily modulate the resonances, band pass or band stop characteristic, as well as the working band.

Abstract:
Abstract The discovery of an account held by Handel at the Bank of England in 1721 offers new documentary information about his financial transactions and evidence for his residence before the move to Brook Street. Careful consideration of the circumstances surrounding this account leads to a reinterpretation of Handel’s short-lived accounts with the Royal African Company in 1720 and sheds light on Handel’s South Sea Annuities account (1723–32). An analysis of the South Sea Annuities account clarifies its origin and explains its pattern of credits and withdrawals, suggests the exact salary Handel received from the Royal Academy of Music as ‘Master of the Orchester’, and indicates that the financial arrangements for Handel’s salary that had been in place from the inception of the Academy were continued at the beginning of the ‘Second Academy’.

Abstract:
: Newly synthesized two kinds of achiral phenylacetylenes having a free-base- or a zinc-porphyrin (1 and Zn1, respectively) were polymerized by using a chiral rhodium catalyst system, Rh+(nbd)[(η6-C6H5)B–(C6H5)3] catalyst and (R)-(+)- or (S)-(–)-1-phenylethylamine ((R)- or (S)-PEA, respectively) cocatalyst. Poly(1) and poly(Zn1) in THF showed a Cotton signal at the absorption region of the porphyrin and the main chain in the circular dichroism (CD) spectra. This result suggests that poly(1) and poly(Zn1) exist in a conformation with an excess of one-handed helix sense and the porphyrin moiety arranged in chiral helical fashion. The one-handed helical structure of poly(1) could be sustained in a mixture of THF/HMPA (10/2, v/v) due to stabilizing by stacking effect of porphyrin moieties along the main chain. This is the first example about helix-sense-selective polymerization by using Rh+(nbd)[(η6-C6H5)B–(C6H5)3] catalyst. Additionally, poly(Zn1) showed about 10 times larger CD intensity in comparison with poly(1). This result suggests the regularity of arrangement of the porphyrin in poly(Zn1) is higher compared with poly(1). Spatial arrangement of porphyrins was achieved by utilizing a one-handed helical poly(phenylacetylenes) as a template.

Abstract:
A periodically inhomogeneous medium is constructed by stacking up unit cells made of (identical) structurally chiral slabs. Each structurally chiral slab is comprised of a certain number of identical biaxially anisotropic plates, the consecutive optic axes describing either a right- or a left-handed spiral. The characteristic matrix of the unit cell is obtained and used with the Floquet-Lyapunov theorem to obtain the electromagnetic fields in the periodic medium. When the unit cell thickness is very small compared to the principal wavelengths in the biaxial plates, the periodically inhomogeneous biaxial medium is shown to be equivalent to a homogeneous biaxial medium, the two optic axes of the equivalent medium being dependent on the handedness of the periodic medium.

Abstract:
Background: As research on quadruped robots grows, so does the variety of designs available. These designs are often inspired by nature and finalized around various technical, instrumentation-based constraints. However, no systematic methodology of kinematic parameter selection to reach performance specifications is reported so far. Kinematic design optimization with objective functions derived from performance metrics in dynamic tasks is an underexplored, yet promising area. Methods: This article proposes to use genetic algorithms to handle the designing process. Given the dynamic tasks of jumping and trotting, body and leg link dimensions are optimized. The performance of a design in genetic algorithm search iterations is evaluated via full-dynamics simulations of the task. Results: The article presents comparisons of design results optimized for jumping and trotting separately. Significant dimensional dissimilarities and associated performance differences are observed in this comparison. A combined performance measure for jumping and trotting tasks is studied too. It is discussed how significantly various structural lengths affect dynamic performances in these tasks. Results are compared to a relatively more conventional quadruped design too. Conclusions: The task-specific nature of this optimization process improves the performances dramatically. This is a significant advantage of the systematic kinematic parameter optimization over straight mimicking of nature in quadruped designs. The performance improvements obtained by the genetic algorithm optimization with dynamic performance indices indicate that the proposed approach can find application area in the design process of a variety of robots with dynamic tasks.

Using the finite element method to simulate the rotation construction phase of the bridge by the way of normal erection calculation, the effect of several different factors to the tower’s instability is analyzed in detail. On the basis, we obtained the effective measure to ensure the tower stable. Meanwhile, survey the tower’s stress and deformation to supervise the tower during the rotation construction. Finally control tower top displacement and its foot stress to guarantee the rotation construction of the CFST arch bridge quality and safety.

Abstract:
A procedure has been developed for isolating gold-fish skeletal muscle thick filaments that preserves the near-helical arrangement of the myosin cross-bridges under relaxing conditions. These filaments have been examined by electron microscopy and computer image analysis. Electron micrographs of the negatively stained filaments showed a clear periodicity associated with the crossbridges, with an axial repeat every 42.9 nm. Computed Fourier transforms of the negatively stained filaments showed a series of layer lines confirming this periodicity, and were similar to the X-ray diffraction patterns of fish muscle obtained by J. Hartford and J. Squire. Analysis of the computed transform data and filtered images of the isolated fish filaments demonstrated that the myosin crossbridges lie along three strands. Platinum shadowing demonstrated that the strands have a right-handed orientation, and computed transforms and filtered images of the shadowed filaments suggest that the crossbridges are perturbed both axially and azimuthally from an ideal helical arrangement.

Abstract:
Different types of classifiers for acoustic partial discharge (PD) pattern classification have been widely discussed in the literature. The classifier performance mainly depends on the measurement conditions (location and type of the PD, acoustic sensor position and frequency response) as well as extracted features. Recent research posits that features extracted by singular value decomposition (SVD) can exhibit the natural characteristics and energy contained in the signal. Though the technique by itself is not novel, in this paper, SVD is employed for PD classification in a revised way starting from data arrangement in Hankel form, to embedding the hypergraph-based features and finally to extracting the required set of optimal features. The algorithm is tested for various measurement conditions that include the influences of various PD locations and oil temperatures. The robustness of the algorithm is also tested using noisy PD signals. Experimental results show the proposed feature extraction method supremacy.

Abstract:
Violations of international humanitarian law (IHL) are a global concern. The enforcement of IHL has traditionally focused on the State level. As States have shown an unwillingness or inability to address violations, attention has moved to the international level primarily through universal approaches such as the International Criminal Court. However, experience has demonstrated that universal approaches also have their limitations. This article argues that regional arrangements offer the possibility of strengthening the enforcement of IHL. As regional arrangements occupy a distinct space between particular local conditions and the universalising tendencies of the global system, they are well placed to handle the various concerns and considerations surrounding the enforcement of IHL.

Abstract:
There are two types of destination interdependence; one arises because of people's preferences towards destination activities, and the other because of the locational arrangement of space. Destination interdependence affects spatial behaviour. In a previous paper it was shown that the conventional gravity model can handle neither aspect of destination interdependence. In this paper it is shown that the competing-destinations model, as a reformulated gravity prototype, is at best able to describe only locational structure effects.

Abstract:
16 right-handed men and 19 women were asked to feel various sized wooden cubes with the dominant hand for 2 sec. (without visual feedback) and then to select this cube from a random visual arrangement of cubes (tactile-visual matching) after a brief delay. The accuracy for men and women for this task did not differ significantly; however, the accuracy was significantly correlated ( rho = 0.61) with a history of complex partial epileptic-like signs for the women but not for the men. The results support the hypothesis that elevated scores for complex partial epileptic-like signs in right-handed women enhance their capacity to associate different perceptual domains of the same stimuli because there is elevated activity within the (multimodal) hippo-campal-amygdaloid system (sensory-limbic hyperconnectionism) and the correlative enhanced intercalation between the right and left temporoparietal lobes.

Abstract:
AbstractPolycystic echinococcosis, caused by the larval stage (metacestode) of the small-sized tapeworm, Echinococcus vogeli, is an emerging parasitic zoonosis of great public health concern in the humid tropical rainforests of South and Central America. Because morphological and morphometric characteristics of the metacestode are not well known, hydatid cysts from the liver and the mesentery were examined from patients following surgical procedures. Whole mounts of protoscoleces with rostellar hooks were examined under light and confocal laser scanning microscopy. Measurements were made of both large and small hooks, including the total area, total length, total width, blade area, blade length, blade width, handle area, handle length and handle width. The results confirmed the 1:1 arrangement of hooks in the rostellar pad and indicated, for the first time, that the morphometry of large and small rostellar hooks varies depending upon the site of infection. Light and confocal microscopy images displayed clusters of calcareous corpuscles in the protoscoleces. In conclusion, morphological features of large and small rostellar hooks of E. vogeli are adapted to a varied environment within the vertebrate host and such morphological changes in calcareous corpuscles occur at different stages in the maturation of metacestodes.

Abstract:
Anthracene-based semiconductors are a class of molecules that have attracted interest due to their air stability, planarity, potential for strong intermolecular interactions, and favorable frontier molecular orbital energy levels. In this study seven novel 9,10-anthracene-based molecules were synthesized and their optical, electrochemical, and thermal properties were characterized, along with their single crystal arrangement. We found that functionalization of the 9,10-positions with different phenyl derivatives resulted in negligible variation in the optical properties with minor (±0.10 eV) changes in electrochemical behavior, while the choice of phenyl derivative greatly affected the thermal stability (Td > 258 °C). Preliminary organic thin film transistors (OTFTs) were fabricated and characterized using the 9,10-anthracene-based molecules as the semiconductor layer. These findings suggest that functionalization of the 9,10-position of anthracene leads to an effective handle for tuning of the thermal stability, while having little to no effect on the optical properties and the solid-state arrangement

Full text
Abstract:
A finite-volume method is presented for calculating incompressible 3-D flows with curved irregular boundaries. The method employs structured nonorthogonal grids, cell-centered variable arrangement, and Cartesian velocity components. A special interpolation procedure for evaluating the mass fluxes at the cell-faces is used to avoid the nonphysical oscillation of flow variables usually encountered with the cell-centered arrangement. The SIMPLE algorithm is used to handle the pressure-velocity coupling. A recently proposed low diffusive and bounded scheme is introduced to approximate the convection terms in the transport equations. The computer code and the relevant data structure are so organized that most of the code except the implicit linear solver used is fully vectorizable so as to exploit the potential of modern vector computers. The capabilities of the numerical procedure are demonstrated by application to a few internal and external three-dimensional laminar flows. In all cases the CPU-time on a grid with typically 28,000 grid nodes was below half a minute.

Abstract:
Existing commercial technologies do not adequately meet the requirements for tracking in fully enclosed Virtual Reality displays. We present a novel six degree of freedom tracking system, the Hedgehog; which overcomes several limitations inherent in existing sensors and tracking technology. The system reliably estimates the pose of the user's head with high resolution and low spatial distortion. Light emitted from an arrangement of lasers projects onto the display walls. An arrangement of cameras images the walls and the two-dimensional centroids of the projections are tracked to estimate the pose of the device. The system is able to handle ambiguous laser projection configurations, static and dynamic occlusions of the lasers, and incorporates an auto-calibration mechanism due to the use of the SCAAT (single constraint at a time) algorithm. A prototype system was evaluated relative to a state-of-the-art motion tracker and showed comparable positional accuracy (1–2 mm RMS) and significantly better absolute angular accuracy (0.1° RMS).

Abstract:
Pseudoazurin from the denitrifying bacteriumAlcaligenes faecalis(AfPAz) is a blue copper protein and functions as an electron donor to copper-containing nitrite reductase (CuNIR). Conventionally,AfPAz has been crystallized using highly concentrated ammonium sulfate as a precipitant. Here, a needle-like crystal ofAfPAz grown in a solution containing a macromolecular precipitant, polyethylene glycol 8000 (PEG 8000), is reported. The crystal belonged to space groupP61, with unit-cell parametersa=b= 68.7,c= 94.2 Å. The structure has been determined and refined at 2.6 Å resolution. The asymmetric unit contained twoAfPAz molecules contacting each other on negatively charged surfaces. The molecular packing of the crystal showed a right-handed double-helical arrangement ofAfPAz molecules and hence of blue copper sites. This structure provides insight into the excluded-volume effect of PEG and the manner of assembly ofAfPAz.

Abstract:
Abstract Research into representation learning models of lexical semantics usually utilizes some form of intrinsic evaluation to ensure that the learned representations reflect human semantic judgments. Lexical semantic similarity estimation is a widely used evaluation method, but efforts have typically focused on pairwise judgments of words in isolation, or are limited to specific contexts and lexical stimuli. There are limitations with these approaches that either do not provide any context for judgments, and thereby ignore ambiguity, or provide very specific sentential contexts that cannot then be used to generate a larger lexical resource. Furthermore, similarity between more than two items is not considered. We provide a full description and analysis of our recently proposed methodology for large-scale data set construction that produces a semantic classification of a large sample of verbs in the first phase, as well as multi-way similarity judgments made within the resultant semantic classes in the second phase. The methodology uses a spatial multi-arrangement approach proposed in the field of cognitive neuroscience for capturing multi-way similarity judgments of visual stimuli. We have adapted this method to handle polysemous linguistic stimuli and much larger samples than previous work. We specifically target verbs, but the method can equally be applied to other parts of speech. We perform cluster analysis on the data from the first phase and demonstrate how this might be useful in the construction of a comprehensive verb resource. We also analyze the semantic information captured by the second phase and discuss the potential of the spatially induced similarity judgments to better reflect human notions of word similarity. We demonstrate how the resultant data set can be used for fine-grained analyses and evaluation of representation learning models on the intrinsic tasks of semantic clustering and semantic similarity. In particular, we find that stronger static word embedding methods still outperform lexical representations emerging from more recent pre-training methods, both on word-level similarity and clustering. Moreover, thanks to the data set’s vast coverage, we are able to compare the benefits of specializing vector representations for a particular type of external knowledge by evaluating FrameNet- and VerbNet-retrofitted models on specific semantic domains such as “Heat” or “Motion.”

Full text
Abstract:
In nature and in the test tube, nucleic acids occur in many different forms. Apart from single-stranded, coiled molecules, DNA and RNA prefer to form helical arrangements, in which the bases are stacked to shield their hydrophobic surfaces and expose their polar edges. Focusing on double helices, we describe the crucial role played by symmetry in shaping DNA and RNA structure. The base pairs in nucleic-acid double helices display rotational pseudo-symmetry. In the Watson–Crick base pairs found in naturally occurring DNA and RNA duplexes, the symmetry axis lies in the base-pair plane, giving rise to two different helical grooves. In contrast, anti-Watson–Crick base pairs have a dyad axis perpendicular to the base-pair plane and identical grooves. In combination with the base-pair symmetry, the syn/anti conformation of paired nucleotides determines the parallel or antiparallel strand orientation of double helices. DNA and RNA duplexes in nature are exclusively antiparallel. Watson–Crick base-paired DNA or RNA helices display either right-handed or left-handed helical (pseudo-) symmetry. Genomic DNA is usually in the right-handed B-form, and RNA double helices adopt the right-handed A-conformation. Finally, there is a higher level of helical symmetry in superhelical DNA in which B-form double strands are intertwined in a right- or left-handed sense.

Abstract:
The extractive industries and local communities in the Russian Arctic make socio-economic agreements to support social and environmental initiatives in the territories of their operations. The extractive industries address social responsibilities through grant projects and social investments. In the framework of social investments, major industrial corporations are supposed to distribute benefits obtained from resource exploitation to stakeholders who are affected by industrial operations. This article presents different forms of benefit-sharing arrangements and how they work in practice in the context of contracting for natural resources (oil, gas, metals and minerals) in Russia. The analysis outlines specific types of contracts and how they are implemented. While benefit-sharing arrangements can provide some benefits for local and regional stakeholders, it is controversial whether these arrangements can improve the situation as far as even-handed sharing of society’s environmental risks, benefits, and impacts is concerned. The article discusses how voluntary social partnership agreements in line with corporate citizenship and stakeholder management can alleviate problems between local people and industries in the Russian Arctic.

Abstract:
Plant photosynthetic (thylakoid) membranes are organized into complex networks that are differentiated into 2 distinct morphological and functional domains called grana and stroma lamellae. How the 2 domains join to form a continuous lamellar system has been the subject of numerous studies since the mid-1950s. Using different electron tomography techniques, we found that the grana and stroma lamellae are connected by an array of pitch-balanced right- and left-handed helical membrane surfaces of different radii and pitch. Consistent with theoretical predictions, this arrangement is shown to minimize the surface and bending energies of the membranes. Related configurations were proposed to be present in the rough endoplasmic reticulum and in dense nuclear matter phases theorized to exist in neutron star crusts, where the right- and left-handed helical elements differ only in their handedness. Pitch-balanced helical elements of alternating handedness may thus constitute a fundamental geometry for the efficient packing of connected layers or sheets.

Service at the “Kelurahan” is a very important part in determining the success of development, especially in public service. The problem faced is the lack of skill level of the “Kelurahan” apparatus with the more dynamic demands of the community and the archive management system is still conventional and manual that is writing the identity of the archive into the book agenda, expedition, control card, and borrowed archive card, so it takes a more practical electronic system, effective and efficient so required to develop themselves in order to improve public services. Conventional administration and archive management must be transformed into cloud-based computing (digital), for which archiving managers should always be responsive and follow these developments and wherever possible in order to utilize for archival activities, with greater access expected archives are evidence at once able to talk about historical facts and events and be able to give meaning and benefit to human life, so archives that were only visible and readable at archival centers can now be accessed online, and even their services have led to automated service systems. Using Microsoft Access which its main function is to handle the process of data manipulation and manufacture of a system, this system is built so that the bias runs on Cloud which means Cloud itself is a paradigm in which information is permanently stored on servers on the internet and stored. The purpose of this program is the implementation of administrative management that has been based cloud computing (digital) and is expected to be a solution in managing the archive so that if it has been designed and programmed, it can be stored in the computer and benefi- cial to the “Kelurahan” apparatus and add in the field of management archives in the form of improving the quality of service to the community, can facilitate and scientific publications.

Our case evidence finds that in addition to cost savings, access to reliable labor is an important motivation for participating in a sharing arrangement.

Abstract:
ABSTRACT The sheath of the filamentous, gliding cyanobacteriumPhormidium uncinatum was studied by using light and electron microscopy. In thin sections and freeze fractures the sheath was found to be composed of helically arranged carbohydrate fibrils, 4 to 7 nm in diameter, which showed a substantial degree of crystallinity. As in all other examined motile cyanobacteria, the arrangement of the sheath fibrils correlates with the motion of the filaments during gliding motility; i.e., the fibrils formed a right-handed helix in clockwise-rotating species and a left-handed helix in counterclockwise-rotating species and were radially arranged in nonrotating cyanobacteria. Since sheaths could only be found in old immotile cultures, the arrangement seems to depend on the process of formation and attachment of sheath fibrils to the cell surface rather than on shear forces created by the locomotion of the filaments. As the sheath in P. uncinatum directly contacts the cell surface via the previously identified surface fibril forming glycoprotein oscillin (E. Hoiczyk and W. Baumeister, Mol. Microbiol. 26:699–708, 1997), it seems reasonable that similar surface glycoproteins act as platforms for the assembly and attachment of the sheaths in cyanobacteria. InP. uncinatum the sheath makes up approximately 21% of the total dry weight of old cultures and consists only of neutral sugars. Staining reactions and X-ray diffraction analysis suggested that the fibrillar component is a homoglucan that is very similar but not identical to cellulose which is cross-linked by the other detected monosaccharides. Both the chemical composition and the rigid highly ordered structure clearly distinguish the sheaths from the slime secreted by the filaments during gliding motility.

Full text
Abstract:
Stylonychia mytilus is a dorsoventrally flattened ciliate with compound ciliary structures arranged in a specific manner on the cell surface. In mirror-image (MI) doublets of this ciliate, two nearly complete sets of ciliary structures are arrayed side-by-side, one in a normal or ‘right-handed’ (RH) arrangement, the other in a reversed or ‘left-handed’ (LH) arrangement. MI-doublets exist in two forms, one with the RH component on the right, the LH component on the left, and feeding structures near the center (‘buccal-adjoining MI-doublet’); the other with the RH component on the left, the LH component on the right, and feeding structures on the lateral edges (‘buccal-opposing MI-doublet’). We describe an operation that can generate either type of MI-doublet. This operation interchanges large anterior and posterior regions of the cell, transposing the original posterior region anteriorly (P—A) and the original anterior region posteriorly (A—P), while retaining the original anteroposterior polarity of each region. Two sets of new ciliary structures then are formed in mirror-image arrangement, with the set in the P—A region oriented normally and the set in the A—P region undergoing a reversal of polarity along its anteroposterior axis. This sometimes creates end-to-end MI forms, but more commonly produces side-by-side MI-doublets through a folding together of the P—A and A—P regions. This folding occurs because one lateral edge of the cell had been removed during the operation; if the left edge was removed, the complex folds to the left and forms a buccal-adjoining MI-doublet, whereas if the right edge was removed, the complex folds to the right and forms a buccal-opposing MI-doublet. Both types can reorganize and later divide true-to-type, although the ‘buccal-opposing’ type is by far the more stable of the two. The generation of mirror-image forms is dependent on the prior abnormal juxtaposition of regions from opposite ends of the cell, and involves a coordinated respecification of large-scale organization. We interpret this response to be a consequence of intercalation of missing intervening positional values in the zone of posterior-anterior abutment.
