description: The "Polygons Intersect Polygons" spatial relationship criterion is a powerful tool for analyzing how different polygon features overlap within a specific area. For example, it can help identify where zoning areas (such as residential, commercial, or industrial zones) intersect with specific land use designations.

 

Similarly, it can show where protected areas, overlap with land designated for other uses, such as agriculture or development.

 

In cadastral mapping, this criterion allows users to see where property boundaries might intersect with municipal or administrative boundaries.

 

In our practical case, when planning large infrastructure projects like utility networks, this tool helps visualize how planned routes intersect with existing property boundaries, aiding in optimization and minimizing disruption.
Working together: a case study of two primary teachers in a peer-centred curriculum implementation program
Creators: name: MacDonnell, Carol Raye
Publisher: name: University of British Columbia
Year: 2009

description: This qualitative case study of two primary teachers during their first year of using a new provincial art curriculum was concerned with the effect of a special relationship between the two teachers on their implementation efforts. The relationship was part of an implementation strategy devised by arts consultants in the school board office; one teacher in every school was designated a “Catalyst Teacher” with a loosely defined role of acting as an on-site “cheerleader” (or catalyst) for the implementation activities of colleagues. This use of a non-specialist member of a staff is related to peer-centred improvement and change efforts discussed in recent literature under such terms as “peer coaching,” “cooperative professional development,” and “collaborative consultation.” It has been shown that a collegial approach to change efforts tends to contribute to the successful implementation of change. Through a series of semistructured interviews with the two teachers individually and together, and supplemented by observations of their art teaching and by interviews and informal conversations with Ministry of Education personnel, the local art consultant, and the school principal, a picture was produced of the meanings constructed by the two teachers about the new curriculum, their roles as teachers and colleagues, the place of art in their total programs, and the effect of the Catalyst Teacher Program on their own implementation efforts. At the end of the interview series, the teachers considered their own progress with the help of Hall and associates’ Levels of Use scale (1975). Looking through the lens of a symbolic interactionist approach to studying this working relationship, I was able to focus on the interdependence of all the elements in the cyclical process of data gathering, sorting, coding, reflecting, and analyzing. The qualitative causal network described by Corbett and Rossman (1989) provided a framework within which the case data could be analyzed and compared to Corbett and Rossman’s findings. The progress of the participants in this study showed the positive effect of the implementation strategy in use in their board. These two teachers’ special qualities of collegiality contributed to their early success, suggesting that conditions of teacher empowerment and collegiality need to precede other specific change efforts. Conditions of distancing between grade-level units within the school, that may have contributed to differences in implementation progress, point to a need to reconsider the wide scale of most implementation efforts.

description: The structure inversion asymmetry at surfaces and interfaces give rise to the Rashba spin-orbit interaction (SOI), that breaks the spin degeneracy of surface or interface states. Hence, when an electric current runs through a surface or interface, this Rashba effect generates an effective magnetic field acting on the electron spin. This provides an additional tool to manipulate the spin state in materials such as Si and Ge that, in their bulk form, possess inversion symmetry (or lack structural inersion asymmetry). The existence of Rashba states could be demonstrated by photoemission spectroscopy at the interface between different metals and Ge(111) and by spin-charge conversion experiments at the Fe/Ge(111) interface even though made of two light elements. In this work, we identify the fingerprint of the Rashba states at the Fe/Ge(111) interface by magnetotransport measurements in the form of a large unidirectional magnetoresistance of up to 0.1 \%. From its temperature dependence, we find that the Rashba energy splitting is larger than in pure Ge(111) subsurface states.

description: The chemical compositions of 26 metal-poor stars that exhibit strong CH and/or C2 molecular bands are determined based on high-resolution spectroscopy. We define carbon-enhanced stars taking account of the carbon abundance ratio ([C/Fe]) and the evolutionary status. Twenty two stars in our sample satisfy our modified definition for Carbon-Enhanced Metal-Poor (CEMP) stars. In addition, we measure Na abundances for nine other carbon-enhanced stars for which abundances of other elements have been previously reported. Combining our new sample with the results of previous work, we investigate the abundance and evolutionary status of a total of 64 CEMP stars. In this paper, we separate the carbon-enhanced objects into Ba-rich and Ba-normal objects, and discuss on (1) the metallicity distributions, (2) the correlation between Ba and C (and C+N) abundances, (3) C abundance distributions, (3) the distributions of evolutionary status, and (5) Na abundances. The implications of these results on the origins of carbon in CEMP stars are discussed.

description: We introduce in this paper a new dataset of annotated pages from books of hours, a type of handwritten prayer books owned and used by rich lay people in the late middle ages. The dataset was created for conducting historical research on the evolution of the religious mindset in Europe at this period since the book of hours represent one of the major sources of information thanks both to their rich illustrations and the different types of religious sources they contain. We first describe how the corpus was collected and manually annotated then present the evaluation of a state-of-the-art system for text line detection and for zone detection and typing. The corpus is freely available for research.

description: By combining the 0.12 square degree F814W Hubble Space Telescope (HST) and Spitzer MIPS 24 micron imaging in the First Look Survey (FLS), we investigate the properties of interacting and merging Mid-Infrared bright and faint sources at 0.2< z <1.3. We find a marginally significant increase in the pair fraction for MIPS 24 micron detected, optically selected close pairs, pair fraction=0.25+/-0.10 at z~1, in contrast to 0.11+/-0.08 at z~0.4, while galaxies below our 24 micron MIPS detection limit show a pair fraction consistent with zero at all redshifts. Additionally, 24 micron detected galaxies with fluxes >0.1mJy are on average five times more likely to be in a close galaxy pair between 0.2< z <1.3 than galaxies below this flux limit. Using the 24 micron flux to derive the total Far-IR luminosity we find that paired galaxies (early stage mergers) are responsible for 27% +/-9% of the IR luminosity density resulting from star formation at z~1 while morphologically classified (late stage) mergers make up 34%+/-11%. This implies that 61%+/-14% of the infrared luminosity density and in turn ~40% of the star formation rate density at z~1 can be attributed to galaxies at some stage of a major merger or interaction. We argue that, close pairs/mergers in a LIRG/ULIRG phase become increasingly important contributers to the IR luminosity and star formation rate density of the Universe at z>0.7.

description: Spin-orbital entanglement in quantum spin-orbital systems is quantified by a reduced von Neumann entropy, and is calculated for the ground state of a coupled spin-orbital chain with $SU(2)\times SU(2)$ symmetry. By analyzing the discontinuity and local extreme of the reduced entropy as functions of the model parameters, we deduce a rich phase diagram to describe the quantum phase transitions in the model. Our approach provides an efficient and powerful method to identify phase boundaries in a system with complex correlation between multiply degrees of freedom.

description: We compute the one loop corrected effective Lagrangian for the neutralino-neutralino-neutral Higgs interactions $χ^{0}_{\ell} χ^{0}_kH^{0}_m$. The analysis completes the previous analyses where similar corrections were computed for the $\bar{f} f H^{0}_m$ couplings, where $f$ stands for Standard Model quarks and leptons and for the chargino-chargino-neutral Higgs couplings $χ^{+}_l χ^{-}_kH^{0}_m$ within the minimal supersymmetric standard model MSSM. The effective one loop Lagrangian is then applied to the computation of the neutral Higgs decays. The sizes of the supersymmetric loop corrections of the neutral Higgs decay widths into $χ^{0}_{\ell} χ^{0}_k$ (${\ell}=1,2,3,4$; $k=1,2,3,4$) are investigated and the supersymmetric loop correction is found to be in the range of $\sim 10%$ in significant regions of the parameter space. By including the loop corrections of the other decay channels $\bar{b} b$, $\bar{t} t$, $\barτ τ$, $\bar{c} c$, and $χ^{-}_i χ^{+}_j$ ($i=1,2$; $j=1,2$), the corrections to branching ratios for $H^{0}_m\to χ^{0}_{\ell} χ^{0}_k$ can reach as high as 50%. The effects of CP phases on the branching ratio are also investigated. A discussion of the implications of the analysis for colliders is given.

description: A puppy's immature immune system makes it susceptible to infection when it is first born. Thankfully, moms create colostrum, a unique type of milk, in the initial days following birth. All of the mother's antibodies are abundant in colostrum. The puppies will be absorbing their mother's immunity as they consume this milk. The mother's antibodies disappear by the time the puppy is 16 to 20 weeks old, so it must continue to develop its own immune system. Through vaccinations, your puppy can develop immunity against common illnesses that could damage them. Pets have increased risk of diseases as they are susceptible to various organisms in the environment directly or indirectly. Vaccinating your pet is much economical than treating them post-infection. The common diseases against which the pets are vaccinated include – Rabies, Infectious Canine Hepatitis, Canine Distemper, Parvovirus and Leptospirosis.

description: In this paper, we consider consensus problems over a network of nodes, where the network is divided into a number of clusters. We are interested in the case where the communication topology within each cluster is dense as compared to the sparse communication across the clusters. Moreover, each cluster has one leader which can communicate with other leaders in different clusters. The goal of the nodes is to agree at some common value under the presence of communication delays across the clusters. Our main contribution is to propose a novel distributed two-time-scale consensus algorithm, which pertains to the separation in network topology of clustered networks. In particular, one scale is to model the dynamic of the agents in each cluster, which is much faster (due to the dense communication) than the scale describing the slowly aggregated evolution between the clusters (due to the sparse communication). We prove the convergence of the proposed method in the presence of uniform, but possibly arbitrarily large, communication delays between the leaders. In addition, we provided an explicit formula for the convergence rate of such algorithm, which characterizes the impact of delays and the network topology. Our results shows that after a transient time characterized by the topology of each cluster, the convergence of the two-time-scale consensus method only depends on the connectivity of the leaders. Finally, we validate our theoretical results by a number of numerical simulations on different clustered networks.

description: We present a stochastic procedure to investigate the correlation spectra of quantum dot superluminescent diodes. The classical electric field of a diode is formed by a polychromatic superposition of many independent stochastic oscillators. Assuming fields with individual carrier frequencies, Lorentzian linewidths and amplitudes we can form any relevant experimental spectrum using a least square fit. This is illustrated for Gaussian and Lorentzian spectra, Voigt profiles and box shapes. Eventually, the procedure is applied to an experimental spectrum of a quantum dot superluminescent diode which determines the first- and second-order temporal correlation functions of the emission. We find good agreement with the experimental data and a quantized treatment. Thus, a stochastic field represents broadband light emitted by quantum dot superluminescent diodes.

description: We present constraints on the dark energy equation-of-state parameter, w=P/(rho c^2), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE supernova survey. We derive a set of constraints on the nature of the dark energy assuming a flat Universe. By including constraints on (Omega_M, w) from baryon acoustic oscillations, we obtain a value for a static equation-of-state parameter w=-1.05^{+0.13}_{-0.12} (stat; 1 sigma) +- 0.11 (sys) and Omega_M=0.274^{+0.033}_{-0.020} (stat; 1 sigma) with a best-fit chi^2/DoF of 0.96. These results are consistent with those reported by the SuperNova Legacy Survey in a similar program measuring supernova distances and redshifts. We evaluate sources of systematic error that afflict supernova observations and present Monte Carlo simulations that explore these effects. Currently, the largest systematic currently with the potential to affect our measurements is the treatment of extinction due to dust in the supernova host galaxies. Combining our set of ESSENCE SNe Ia with the SuperNova Legacy Survey SNe Ia, we obtain a joint constraint of w=-1.07^{+0.09}_{-0.09} (stat; 1 sigma) +- 0.12 (sys), Omega_M=0.267^{+0.028}_{-0.018} (stat; 1 sigma) with a best-fit chi^2/DoF of 0.91. The current SN Ia data are fully consistent with a cosmological constant.

description: The ordering property of the classical pyrochlore Heisenberg antiferromagnet with the ferromagnetic next-nearest-neighbor interaction is investigated by means of a Monte Carlo simulation. The model is found to exhibit a first-order transition at a finite temperature into a peculiar ordered state. While the spin structure factor, i.e., the thermal average of the squared Fourier amplitude of the spin, exhibits a finite long-range order characterized by the commensurate spin order of the period four, the thermal average of the spin itself almost vanishes. It means that, although the amplitude of the spin Fourier component is long-range ordered, the associated phase degree of freedom remains to be fluctuating.

description: United States goat producers face many challenges with regards to marketing. Although the demand for goat products is increasing, the market is fractured. There is a general lack of infrastructure and many producers do not sell their animals or products for fair or profitable prices. Production costs are too high, and there is a need to improve production efficiency. Imports pose a challenge to US goat producers, as domestic production cannot compete with the availability and lower cost of imports. Government regulations hinder market development because non-commercial slaughter is an important aspect of goat marketing, and regulations keep many dairy goat producers from developing a commercial enterprise. In order for the US goat industry to expand and meet the growing demand for products, producers need to combine efficient production practices with profitable marketing strategies.

Emerging teacher identity: a study in learning to teach through the experiences of a secondary social studies methods course
Creators: name: Gibson, Susan Elaine
Publisher: name: University of British Columbia
Year: 2009

description: This qualitative study focused specifically on a secondary social studies methods course in the Faculty of Education at the University of British Columbia. The intent was to generate descriptions of the methods course experience, and to explore student teachers conceptualizations as they made sense out of learning to teach social studies. Eight student teachers in one section of SSED 312: Curriculum and instruction in social studies - Secondary agreed to be a part of this study. These eight were interviewed four times over the duration of the five month study. The first interview, prior to the beginning of the methods course, examined their initial conceptualizations of the nature of social studies and social studies pedagogy. The second interview, after a month of the course, and the third, following a two week practicum at the mid-point of the course, investigated their conceptualizing in response to specific experiences of the methods course and the practicum. The fourth interview, upon completion of the course, investigated any change in how the participants conceptualized social studies and the salient influences on that change. Data were also collected through my regular observation in the methods class. Generally, there was some form of change in the conceptualizations of all eight participants, some to a greater extent than others. These changes included being able to identify self as a social studies teacher; understanding the social studies teacher's moral responsibility, particularly when dealing with value-laden and controversial issues; clarifying the nature of social studies; and learning about social studies pedagogy. Central to the change process were both reflection on, and articulation of, their initial conceptualizations, as the participants experienced the course. The most salient influences on change were both internal and external to the course. Internally, the instructor's provocative teaching style, the nature of the course content, and the emphasis on peer interaction were most influential. Other influences included the short practicum, other course work encountered in the preparatory program, and, being a part of this study.

description: We have carried out a first-principles theoretical study of the magnetically induced polarization in orthorhombic TbMnO3, a prototypical material in which a cycloidal spin structure generates an electric polarization via the spin-orbit interaction. We compute both the electronic and the lattice-mediated contributions to the polarization and find that the latter is strongly dominant. We analyze the spin-orbit induced forces and lattice displacements from both atomic and mode-decomposition viewpoints, and show that a simple model based on nearest Mn--Mn neighbor Dzyaloshinskii-Moriya interactions is not able to account fully for the results. The direction and magnitude of our computed polarization are in good agreement with experiment.

description: Nuclei instance segmentation plays an important role in the analysis of Hematoxylin and Eosin (H&E)-stained images. While supervised deep learning (DL)-based approaches represent the state-of-the-art in automatic nuclei instance segmentation, annotated datasets are required to train these models. There are two main types of tissue processing protocols, namely formalin-fixed paraffin-embedded samples (FFPE) and frozen tissue samples (FS). Although FFPE-derived H&E stained tissue sections are the most widely used samples, H&E staining on frozen sections derived from FS samples is a relevant method in intra-operative surgical sessions as it can be performed fast. Due to differences in the protocols of these two types of samples, the derived images and in particular the nuclei appearance may be different in the acquired whole slide images. Analysis of FS-derived H&E stained images can be more challenging as rapid preparation, staining, and scanning of FS sections may lead to deterioration in image quality. In this paper, we introduce CryoNuSeg, the first fully annotated FS-derived cryosectioned and H&E-stained nuclei instance segmentation dataset. The dataset contains images from 10 human organs that were not exploited in other publicly available datasets, and is provided with three manual mark-ups to allow measuring intra-observer and inter-observer variability. Moreover, we investigate the effects of tissue fixation/embedding protocol (i.e., FS or FFPE) on the automatic nuclei instance segmentation performance of one of the state-of-the-art DL approaches. We also create a baseline segmentation benchmark for the dataset that can be used in future research. A step-by-step guide to generate the dataset as well as the full dataset and other detailed information are made available to fellow researchers at https://github.com/masih4/CryoNuSeg.

description: We explore the mechanism of transverse momentum broadening of fast quarks propagating in nuclei, using Drell-Yan (DY) transverse momentum distributions measured in the experiment E866 at FermiLab with beams of 800 GeV protons. Our theoretical analysis is based on the color dipole approach in the target rest frame, which has provided a successful phenomenological description of a variety of hadronic reactions. The present application is relevant to the regime of short coherence length (SCL), where the spatial extent of the fluctuations of the projectile responsible for the Drell-Yan reaction is short compared to the internucleon spacing. In this limit, momentum broadening comes from initial state interactions and is described as color filtering, i.e. absorption of large-size dipoles leading to diminished transverse separation and hence enhanced transverse momentum. The predictions we present are in good agreement with the E866 data. The interactions leading to the acquisition of transverse momentum arise from the color-dipole cross section determined previously from deep-inelastic scattering on proton targets. Aside from the determination of the color-dipole cross section, no other phenomenological input is needed to explain the experimental results. The mean-square momentum broadening of dileptons determined in a recent separate analysis of the data is likewise well described by our theory. These results confirm that the origin of momentum broadening in DY is the color dipole cross section mediating soft initial state interactions between the parton of the projectile that initiates the reaction and the nucleons of the nucleus, as provided by the color dipole description. Predictions for broadening observables at RHIC are presented.

description: Although the number of camera-based sensors mounted on vehicles has recently increased dramatically, robust and accurate object velocity detection is difficult. Additionally, it is still common to use radar as a fusion system. We have developed a method to accurately detect the velocity of object using a camera, based on a large-scale dataset collected over 20 years by the automotive manufacturer, SUBARU. The proposed method consists of three methods: an High Dynamic Range (HDR) detection method that fuses multiple stereo disparity images, a fusion method that combines the results of monocular and stereo recognitions, and a new velocity calculation method. The evaluation was carried out using measurement devices and a test course that can quantitatively reproduce severe environment by mounting the developed stereo camera on an actual vehicle.

description: The X-ray spectra of luminous Seyfert 1 galaxies often appear to be reflection dominated. In a number of Narrow Line Seyfert 1 (NLS1) galaxies and galactic black holes in the very high state, the variability of the continuum and of the iron line are decoupled, the reflected component being often much less variable than the continuum. These properties have been interpreted as effects of gravitational light bending. In this framework, we present detailed Monte-Carlo simulations of the reflection continuum in the Kerr metric. These calculations confirm that the spectra and variability behaviour of these sources can be reproduced by the light bending model. As an alternative to the light bending model, we show that similar observational properties are expected from radiation pressure dominated discs subject to violent clumping instabilities and, as a result, have a highly inhomogeneous two-phase structure. In this model, most of the observed spectral and variability features originate from the complex geometrical structure of the inner regions of near-Eddington accretion flows and are therefore a signature of accretion physics rather than general relativity.

description: This study attempts to examine the potential differences that exist between male and female students, and between science career choosers and non-science career choosers in terms of factors that were thought to influence their academic and career decision making. Four types of factors are considered: 1) Mathematics and science background; 2) Attitudes toward school science activity; 3) Perceptions of various influences on career choice; 4) Perceptions of their own personality. A survey was carried out in British Columbia between February and June, 1994. The subjects were 316 Grade 12 students randomly drawn from 16 districts (20 schools), and they are considered to be representative of the British Columbia school population. Data for the study were collected by using a previously developed questionnaire (Woolnough, 1991) which was modified by the researcher. The questionnaire was administed in each school by the school counselor. The data were then analyzed by using SPSS Mainframe. The major findings of the study were: 1) Fewer female students selected physical-science related careers in comparison with male students; 2) Science career choosers selected more mathematics and science courses than students selecting a non-science career; the mathematics and science GPA of non-science career choosers was significantly lower than that of science career choosers; 3) Science career choosers thought that "family", "school success", "out-of-school science", and "personality" were more encouraging for them to enter science and engineering careers than did non-science choosers; 4)Male students thought that "family", "school success", and "personality" were more encouraging for them to enter science and engineering careers than did female students. The findings suggest that the important factors that affect students' choice of a career in science and engineering can be: family; school success; school science; out-of-school science; and personality. Suggestions are made for further practice and research to address the issues and concerns raised by the study.

description: We show that the Lyman-alpha optical depth statistics in the proximity regions of quasar spectra depend on the mass of the dark matter halos hosting the quasars. This is owing to both the overdensity around the quasars and the associated infall of gas toward them. For a fiducial quasar host halo mass of (3.0+/-1.6) h^-1 x 10^12 Msun, as inferred by Croom et al. from clustering in the 2dF QSO Redshift Survey, we show that estimates of the ionizing background (Gamma^bkg) from proximity effect measurements could be biased high by a factor of ~2.5 at z=3 owing to neglecting these effects alone. The clustering of galaxies and other active galactic nuclei around the proximity effect quasars enhances the local background, but is not expected to skew measurements by more than a few percent. Assuming the measurements of Gamma^bkg based on the mean flux decrement in the Ly-alpha forest to be free of bias, we demonstrate how the proximity effect analysis can be inverted to measure the mass of the dark matter halos hosting quasars. In ideal conditions, such a measurement could be made with a precision comparable to the best clustering constraints to date from a modest sample of only about 100 spectra. We discuss observational difficulties, including continuum flux estimation, quasar systematic redshift determination, and quasar variability, which make accurate proximity effect measurements challenging in practice. These are also likely to contribute to the discrepancies between existing proximity effect and flux decrement measurements of Gamma^bkg.

description: Στην παρούσα έρευνα συγκρίνονται δύο λαβίδες σύσφιξης ως προς τη κατασκευή ασφαλούς κόμπου στο δακτυλιοειδές ορθοπαιδικό σύρμα. Συγκεκριμένα συγκρίθηκε η κλασική λαβίδα σύσφιξης της ΑΟ/ASIF με μια αυτόματη λαβίδα σύσφιξης.Συνολικά μελετήθηκαν 80 δείγματα δακτυλιοειδών ραμμάτων χωρισμένα σε τέσσερις ομάδες των 20. Στις δύο ομάδες χρησιμοποιήθηκε η κλασική λαβίδα για την κατασκευή του κόμπου και στις άλλες η αυτόματη. Για κάθε λαβίδα, στην καθεμία από τις ομάδες της, χρησιμοποιήθηκε διαφορετική ταχύτητα εφελκυσμού για τη σύγκριση της αντοχής του κόμπου των δειγμάτων. Από την παρούσα εργασία προέκυψαν τα παρακάτω συμπεράσματα: • Η υπό εξέταση αυτόματη λαβίδα σύσφιξης δεν παρουσιάζει διαφορά με την κλασική λαβίδα σύσφιξης του ορθοπαιδικού σύρματος ως προς την αντοχή του κόμπου στον εφελκυσμό, ανεξάρτητα από την ταχύτητα έλξης. • Η αντοχή του κόμπου που κατασκευάστηκε με την υπό εξέταση λαβίδα σύσφιξης δεν διαφέρει σε σχέση με την ταχύτητα έλξης. • Η αντοχή του κόμπου που κατασκευάστηκε με τη κλασική λαβίδα δεν διαφέρει σε σχέση με την ταχύτητα έλξης. • Ο χρόνος που απαιτείται για την κατασκευή του κόμπου με την κλασική λαβίδα είναι μικρότερος από το χρόνο κατασκευής του με την υπό εξέταση λαβίδα σύσφιξης. • Η ορθή σύσφιξη του ορθοπαιδικού σύρματος με την υπό μελέτη αυτόματη λαβίδα εξαρτάται λιγότερο από την εμπειρία του χειρούργου σε σχέση με την κλασική λαβίδα σύσφιξης.
description: In this study two tightening clamps were compared with the aim to construct a safe knot of cerclage wire. Specifically, the classic clamp (AO/ΑSIF) and an automatic wire twister were compared. Eighty specimens of cerclage wires were compared totally. The specimens were divided in four groups of twenty specimens. In the first two groups the classic clamp was used to construct the knot and for the others, the automatic wire twister was used. For every clamp, in every group that it was used a different tension speed was applied to compare the strength of the knot in every specimen. From the present study the following conclusions were extracted: • The automatic wire twister does not show any difference in comparison with the classic clamp as far as the strength of the knot under tension, independent of the tension speed. • The knot strength that was constructed with the automatic wire twister does not differ as far as the tension speed is concerned. • The knot strength that was constructed with the classic clamp does not differ as far as the tension speed is concerned. • The time needed for the construction of the knot with the classic clamp is smaller than the the time needed for the construction of the knot with the automatic wire twister. • The correct tightening of the orthopedic wire with the under testing automatic clamp is less dependent on the experience of the surgeon in comparison with the classic clamp
