Jouvet, Guillaume, Jacques Rappaz, Ed Bueler et Heinz Blatter. « Existence and stability of steady-state solutions of the shallow-ice-sheet equation by an energy-minimization approach ». Journal of Glaciology 57, no 202 (2011) : 345–54. http://dx.doi.org/10.3189/002214311796405852.
Texte intégralRésumé :
AbstractThe existence of solutions of the non-sliding shallow-ice-sheet equation on a flat horizontal bed with a mass balance linearly depending on altitude is proven for fixed margins. Free-margin solutions for the same mass balance do not exist. Fixed-margin solutions show unbounded shear stress and nonzero mass flux at the margin. Steady-state solutions with realistic margins, vanishing ice flux and vanishing shear stress are found numerically for ice sheets with Weertman-type sliding.

Texte intégralRésumé :
Drill chatter degrades hole roundness, hole size, and tool life. This wastes time and money in tools, scrap, and hole rework. Chatter prediction in milling and turning has shown significant benefit to industry; however, researchers have been unable to accurately predict chatter in drilling applications. In the past, the drill, including the chisel edge, was modeled as either a fixed-fixed or fixed-pinned beam (Tekinalp, O., and Ulsoy, A. G., 1989, “Modeling and Finite Element Analysis of Drill Bit Vibrations,” ASME J. Eng. Indust. 111, pp. 148–154), but more recent research (Dilley, D. N., Bayly, P. V., and Schaut, A. J., 2005, “Effects of the Chisel Edge on the Chatter Frequency in Drilling,” J. Sound Vib., 281, pp. 423–428) has shown that a fixed-embedded model using springs improves frequency matching. The effects of the drill margins on dynamics have not been studied. The fixed-fixed or fixed-pinned model will be shown to be inappropriate for modeling the effects of margin engagement, while the spring-end boundary condition can better approximate the frequency increase observed experimentally as the drill margins engage deeper into the hole. In addition, the shifted frequency is well below the frequency found from an analytical fixed-fixed or fixed-pinned beam. Evidence that the margins cause the frequency shift is seen in three-dimensional waterfall plots that show this shift for pilot hole drilling (in which the margins are engaged), but not for tube drilling (in which margins are not engaged).

Texte intégralRésumé :
Resection margins in colorectal cancer carry clinical significance with regard to disease recurrence risk and selection for multimodal adjuvant therapy, especially with circumferential resection margins in rectal cancer. Colorectal cancer specimens are routinely fixed in formalin, which results in specimen and tumor-free margin shrinkage. However, the effects of shrinkage have not traditionally been taken into account when analyzing tumor-free margins. In this prospective study, 46 colorectal cancer specimens were measured in the fresh state and subsequently after formalin fixation for total specimen length, distal resection margin, and radial margin (circumferential resection margin for rectal cancer). The mean reduction after formalin fixation was 17.48 mm (14.7%) for distal resection margin and 1.20 mm (10.5%) for radial margin. For rectal cancer, circumferential resection margin reduction was 0.88 mm (11.8%); this was not affected by neoadjuvant chemoradiotherapy. Duration of formalin fixation did not significantly affect the extent of margin shrinkage. This is the first study to evaluate the effect of formalin fixation on radial resection margins, specifically as it relates to rectal cancer, and it demonstrates that shrinkage from formalin fixation should be a consideration in decision-making where the magnitude of tumor-free margins is small.

Texte intégralRésumé :
Objectives This study was performed to assess skin–muscle–fascia specimen shrinkage and donor site changes, and to compare three techniques of specimen preparation for their effect on specimen shrinkage postexcision and after formalin fixation in feline cadaveric specimens. Methods Fifteen fresh feline cadavers were used for this study. Gelatin spheres were implanted in paired thoracic subcutaneous pockets and subsequently excised with 30 mm lateral margins and a fascial plane as the deep margin. Skin and fascia were either left unsutured, sutured together using four simple interrupted quadrant sutures (‘four-quadrant-sutured’) or sutured together in a continuous pattern (‘circumferentially sutured’). Specimens were measured for tumor-free margins on the excised and fixed specimens. The donor site defect was assessed for enlargement after specimen excision. Statistical analyses were performed to assess the donor site enlargement, and the influence of preparation technique on margin size, with significance set at P <0.05. Results The closest skin margins on the excised and fixed specimens were significantly smaller than the planned 30 mm margins; however, no significant difference was found between postexcision and postfixation specimens. No significant differences were found between the three techniques ( P = 0.74) with regard to margins either after excision or fixation. The fascial and skin defects of the donor site were significantly larger than the planned excision. Conclusions and relevance Surgically obtained feline skin–muscle–fascia specimens will significantly decrease in size prior to formalin fixation, resulting in falsely decreased measurements from tumor to tissue margins. Affixing the skin to the fascia does not significantly influence this decrease in margin size in feline tissue specimens at this location.

Hertig, Paul. « The Multi-ethnic Journeys of Jesus in Matthew : Margin-Center Dynamics ». Missiology : An International Review 26, no 1 (janvier 1998) : 23–35. http://dx.doi.org/10.1177/009182969802600103.
Texte intégralRésumé :
Matthew paints geographical portraits of marginality through the continuous journeys of Jesus, the migrant God. Galilee of the Gentiles, a crossroads of cultures and empires, served as the appropriate mission base for Jesus' center-margin journeys. Matthew paints social portraits of marginality through Jesus' encounters with individuals such as the centurion, the Canaanite woman, and the Galilean women who follow Jesus to the cross and the tomb. This study redefines marginality as a continuous journey to and from margins and centers, thus departing from the traditional definition of static in-betweenness. The church today is neither a fixed center nor a margin, but discovers its identity through its journeys on the way to and from multiple margins and centers.

Texte intégralRésumé :
This paper studies the role of the exchange rate regime for trade of new products. It first provides VAR evidence that a rise in external productivity shifts trade away from new products and more so in fixed regimes. Then, it presents a model with firm dynamics in line with this evidence. We argue that exchange rate policy can affect firms’ entry decisions with consequences for the competitiveness of a country’s exports well beyond the short run. In our setup, fixed exchange rates can foster the competitiveness of firms that trade new products, while flexible rates favor firms that produce mature products.

Kell, M. R., C. Dunne, C. Canning et M. Morrow. « The effect of margin status on local recurrence following breast conservation and radiation therapy for DCIS ». Journal of Clinical Oncology 25, no 18_suppl (20 juin 2007) : 597. http://dx.doi.org/10.1200/jco.2007.25.18_suppl.597.
Texte intégralRésumé :
597 Background: There is no consensus on what constitutes an adequate surgical margin in patients receiving breast conserving surgery (BCS) and postoperative irradiation (RT) for ductal carcinoma in situ (DCIS). Inadequate margins may result in high local recurrence, and excessively large resections may lead to poor cosmetic outcome without oncological benefit. Methods: A comprehensive search for published trials which examined outcomes after adjuvant RT following BCS for DCIS was performed using medline and cross referencing available data. Reviews of each study were conducted, and data were extracted. Fixed and random effects methods were used to combine data. Primary outcomes were in breast tumour recurrence (IBTR) related to surgical margins. Results: Analysis of 3,606 patients from randomized trials confirms that patients with negative margins are significantly less likely to recur than those with positive margins after RT (RR 0.53, 95% CI= 0.42 to 0.66, p<0.01). Combined data from randomized and non randomized trials, of 5,500 patients, demonstrates that where the margin status is close or unknown there is significant risk of IBTR compared to a negative margin (RR=1.68, 95% CI= 1.22–2.33, p<0.01). When specific margin thresholds are examined a 2 mm margin is superior to less than 2 mm (OR=0.67, 95% CI 0.51 -0.89, p<0.01), however we saw no significant difference in the rate of IBTR between a 2 mm margin and >5 mm (OR=1.49, 95% CI 0.54 to 4.9, p>0.05). Conclusions: Surgical margins negative for DCIS should be obtained following BCS for DCIS. A margin threshold of 2mm appears be as good as a larger margin when BCS for DCIS is combined with RT. No significant financial relationships to disclose.

Texte intégralRésumé :
This paper presents a method to determine parameters of BTB (back-to-back) converters in terms of the enhancement of interface flow margins. Interface flow margin is by definition a measure of how much active power can be transferred from the external areas to the study area with the fixed load demand, and it is mainly constrained by system voltage stability. BTB converters are controllable equipments with the active power flow through them, and its DC link in fact can divide the AC systems at the location and hence can reduce the fault current level. This paper first calculates margin enhancement sensitivities at the nose point of F-V curves and formulates an optimization problem to update the BTB parameters to improve the margins. This procedure is repeated performed until the required margin enhancement is achieved.

Texte intégralRésumé :
A fixed (conventional) weed management strategy in corn was compared to three other strategies (two mixed and one flexible) in terms of weed control, grain yield, gross margin (gross income minus herbicide treatment costs), and herbicide use under furrow irrigation for four consecutive years. The fixed strategy prespecified preplanting, preemergence, postemergence, and layby herbicides. The flexible strategy herbicide treatments were specified by a computer bioeconomic model. Model decisions were based on weed seed in soil before planting, weed densities after corn emergence, herbicide costs, expected corn grain yield and selling price, and other parameters. The two mixed strategies were a combination of fixed and flexible strategies and designated either specified soil-applied herbicides (mixed/soil), or no soil-applied herbicide (mixed/no soil); postemergence treatments were determined by the model. Average corn grain yield was 10 280 kg ha–1and gross income was 920 $ ha–1and neither differed among strategies. Total weed density and gross margin were significantly higher for the mixed/no soil and flexible strategies compared to the mixed/soil and fixed strategies. Total weed density averaged 28 720, 28 100, 10 910, and 680 plants ha–1for the mixed/no soil, flexible, mixed/soil, and fixed strategies, respectively. Annual gross margins for the four strategies averaged 885, 875, 845, and 810 $ ha–1, respectively. Herbicide use over the 4-yr period for these four strategies averaged 3.8, 5.3, 20.5, and 26.9 kg ha–1, respectively, and each value differed from the other. Thus, weeds can be managed in corn, gross margins increased, and herbicide use decreased by employing a bioeconomic weed-corn model to make weed management decisions.

Texte intégralRésumé :
ABSTRACTThe wake vortex of lifting surfaces such as wind turbine blades or fixed-wing aircraft can heavily affect the blade aerodynamics of rotorcraft. Using blade element theory, the pilot control inputs required to mitigate such vortex effects are estimated and compared to the available control margin at the operating condition of interest. In contrast, when no pilot action is performed, the rotor blade flapping caused by the vortex is evaluated and compared to available margins. It is a safety concern when the remaining margins become zero. The influence of the vortex strength, its core radius and orientation to the rotor disk are evaluated and the effect of rotor blade characteristics (Lock number, natural frequency) is investigated.

Texte intégralRésumé :
Purpose The purpose of this paper is to examine the distribution of learning and training opportunities in the Finnish workforce. It will concentrate on the sectors of the workforce that lack these opportunities. Design/methodology/approach The Working Conditions Barometer (WCB) data from 2008, 2009 and 2010 are used (N = 3,326) in this investigation. The focus of the study is to examine those employees whose learning and training opportunities fail to match the positive visions of the current “super professional hype”. The problems associated with the workforce training margin are considered as a part of the so-called work process debate. Findings Findings suggest that age, gender, type of industry and socioeconomic status have an independent influence on an individual’s presence in the training margin: women, older employees, employees in manufacturing and the private service sector and manual workers have a greater risk than others do. The relative differences between the social classes are still prevalent: incapacity and marginalization are primarily working class problems. Practical implications The workers should collectively demand certain benefits more forcefully, even when working under fixed-term contracts. Employers should be pressured to organise development opportunities and training for the fixed-term employees, including the type of training that not only benefits an employee in that one company but also the employees’ working life in general. Employers should be persuaded to organise the type of training that improves the chances of a fixed-term or otherwise powerless employee to find a new, perhaps better and more secure job. Originality/value Because the percentage of response to the WCB is exceptionally high, 80 per cent on average, the information obtained from the random sample can be generalised to represent all of the working wage earners in Finland and in a European context as well.

Texte intégralRésumé :
e12590 Background: Approximately 30% of breast cancer patients undergoing breast-conserving surgery (BCS) require re-excision(s) to obtain clear margins, causing delays in adjuvant treatment, poor aesthetic results, and increased infection rates, costs, and patient anxiety. Frozen section pathology assessment (FSA) reduces re-excision rates from 27% to 6%, but FSA extends operative times and has a false negative rate of 17%. Photo-Acoustic Remote Sensing (PARS) is a new laser-based light microscope that permits non-contact cellular resolution imaging of unstained tissues. Methods: We used an ultraviolet reflection-mode PARS microscope to study i) formalin-fixed, paraffin embedded (FFPE) breast tissue blocks, ii) unstained thin sections of FFPE invasive ductal carcinoma and ductal carcinoma in situ, iii) formalin fixed bulk surgical specimens of benign and malignant human breast tissue, and iv) benign and malignant fresh rodent mammary tissue without fixation, processing, or staining. Fresh tissues were imaged after a range of warm ischemic times and across a range of cold ischemic times in neutral phosphate buffered saline at 4°C. For each condition, an ultraviolet laser was used to excite DNA and other cellular components in these samples, and signals were captured using a continuous-wave detection laser. The PARS signal was false-colored to closely replicate traditional hematoxylin and eosin staining. Results: In all fixed tissues, PARS virtual histology images were of diagnostic quality, permitted margin assessment, and analogous to transmission light microscopy of standard hematoxylin and eosin-stained FFPE slides, achieved without tissue sectioning or tissue staining. Furthermore, PARS microscopy also provided cellular level virtual histology images in fresh breast tissue with warm and cold ischemic times ranging from twenty minutes to two hours; these images have no available clinical comparators as non-contact cellular level imaging of unprocessed fresh tissue has not previously been reported. In aggregate, we demonstrate the feasibility of PARS to provide diagnostic and margin assessment images across a range of tissues including formalin fixed and freshly resected, unstained, unprocessed breast tissue. Conclusions: PARS is a new microscope technology addressing the practical needs of intraoperative margin assessment during BCS: i) no requirement for tissue staining, ii) rapid acquisition of hematoxylin and eosin-like images without the requirement for tissue freezing, embedding, or sectioning, iii) diagnostic quality cellular resolution, and iv) assessment of resected bulk tissue margins. In principle, this technology may also permit label-free non-contact intraoperative margin assessment of the surgical cavity. These data support the clinical development and evaluation of PARS microscopic intraoperative assessment of BCS margins.

Texte intégralRésumé :
PurposeThe purpose of this paper is to examine the determinants of bank margins in the Yemeni banking sector for Islamic and conventional banks. The first objective is to investigate whether there is a significant difference between the margins of conventional and Islamic banks. The second objective is to examine whether efficiency represents an influential factor in determining bank margins for Islamic and conventional banks controlling for other micro and macro variables.Design/methodology/approachUsing a data set of banks in Yemen for the post-liberalisation period from 1996 to 2011, the study utilises panel data with unbalanced observations for 16 banks, of which four are Islamic banks and the remainder conventional banks. Parametric and non-parametric techniques are complemented by dummy variable regression using random effects. Panel fixed effects regression was also undertaken as a robustness check.FindingsThe paper finds that the overall bank margin in Yemen has steadily decreased during the observation period with the exception of the year 2011. The parametric and non-parametric results show that the bank margins are significantly higher for conventional banks than for Islamic banks. The results provide evidence that bank margins are related to neither types of efficiency, but are affected by capitalisation, size, the opportunity cost of the reserve and liquidity, although the impact is shaped differently for Islamic and conventional banks.Practical implicationsThe paper provides a basis for regulators and bankers for assessing the viability of the banking sector and proposes policies to restructure the industry to enhance its performance.Originality/valueThis paper adds value to the literature for the Yemeni banking sector and extends the previous research on the determinants of bank margins by focusing on the impact of efficiency on bank margins. Also, it compares the Islamic banks with different types of conventional banks in Yemen in their margins trend.

Texte intégralRésumé :
We have interpreted 27,550 km of deep-penetrating, 2D-seismic reflection profiles across the South Atlantic conjugate margins of Uruguay/Southern Brazil and Namibia. These reflection profiles reveal in unprecedented detail the lateral and cross-sectional, asymmetrical distribution of voluminous, postrift volcanic material erupted during the Barremian-Aptian (129–125 Ma) period of early seafloor spreading in the southernmost South Atlantic. Using this seismic grid, we mapped the 10–200 km wide, continental margin-parallel limits of seaward-dipping reflector (SDR) complexes — that are coincident with interpretations from previous workers using seismic refraction data from the South American and West African conjugate margins. Subaerially emplaced and tabular SDRs have rotated downward 20° in the direction of the mid-Atlantic spreading ridge and are up to 22 km thick near the limit of continental crust. The SDR package is wedge shaped and thins abruptly basinward toward the limit of oceanic crust where it transitions to normal, 6–8 km thick oceanic crust. We have developed a model for the conjugate rifted margins that combine diverging tectonic plates and northwesterly plate motion relative to a fixed mantle position of the mantle plume. Our model explains an approximately 30% higher volume of SDRs/igneous crust on the trailing Namibian margin than on the leading Brazilian margin during the syn- and postrift phases. Our model for volcanic margin asymmetry in the South Atlantic does not require a simple shear mechanism to produce the asymmetrical volcanic material distribution observed from our data and from previously published seismic refraction studies. Determining the basinward extent of the extended continental basement is crucial for understanding basin evolution and for hydrocarbon exploration. Although these conjugate margins have evolved asymmetrically, their proximity during the early postrift stage suggests a near-equivalent, early basin evolution and similar hydrocarbon potential. Understanding the tectonic and magnetic processes that produce these observed asymmetries is critical for understanding volcanic passive margin evolution.

Texte intégralRésumé :
Marginal leakage is the intrusion into the space between all the restorative materials and cavity walls of fluids, bacteria, and ions. It can cause irritation of the pulp, change of color in the tooth and secondary caries, and may also result in restoration failure. The freshly placed prosthetic margins invariably leak. As time goes by there is a rise in marginal leakage associated with the manufacture of corrosion products and the expansion of other materials into the space between the tooth and the prosthesis. Dental researchers have been interested in the efficacy of the restorative materials to seal cavity margins against the entry of salivary constituents for some time. Some studies have shown that normal dentin would allow the penetration of dyes into human teeth's tubules. An analysis of later micro-leakage studies reveals that the structure of the dentin is permeable to the diffusion of fluids by natural and acquired defects. Because the enamel surface contains natural cracks and that allow the fluid to penetrate, the enamel can also have areas of hypo calcification, , chemical breakdown, abrasion, and carious lesions that increase penetration. However, enables the transportation of fluids by processes. Cutting dentin with dental pressure increases the exposed surface area and thus increases the amount of tubules available for fluid transfer into the pulp chamber. While ionic charge and chemical reactivity of diffusing fluids lead to marginal leakage, the physical and chemical character of restorative materials, and the operator's clinical skills are equally essential.

The purpose of this study is to find out working capital in an independent Islamic bank, the financial performance of an independent Islamic bank in Jambi by using a liquidity ratio analysis tool (current ratio, cash ratio) and profitability ratio (profit margin) and there is also a significant relationship between current ratio cash ratios and profit margins with working capital at the Islamic bank Mandiri jambi. The analytical tool used is multiple linear regression. Study the significant relationship between current ratio (X1), cash ratio (X2) profit margin (X3) as the independent variable and working capital as the dependent variable. The results of working capital analysis at the jambi independent Islamic bank have fixed assets and current assets with a total average current assets from 2016 to 2019 of Rp 88,919,015.5 and for average fixed assets from 2016 to 2019 of IDR 856,841.06. Analysis results Financial performance through liquidity ratios namely current ratio and cash ratio obtained an average current ratio from 2016 to 2019 of 115.67%, and obtained an average cash ratio from 2016 to 2019 of 1.55%. For profitability ratios namely profit margins can be obtained an average profit margin from 2016 to 2019 of 72.82% with very good criteria because it exceeds the maximum limit of the standard ratio. The test results on the relationship of the current ratio, cash ratio and profit margin with working capital obtained a person correlation current ratio of 1,000 means perfect correlation and there is a relationship between the current ratio with working capital. For cash ratio with a person correlation value of cash ratio of 1,000 means perfect correlation and there is a relationship between cash ratio and working capital. For the value of person correlation margin of 1,000 means that it means perfect correlation and there is a relationship between profit margin and working capital. It can be concluded that working capital influences the current ratio, cash ratio and profit margin.

Texte intégralRésumé :
ABSTRACT Objective Transoral laser microsurgery (TLM) for endoscopic excision of head and neck cancers of the upper aerodigestive tract has become an accepted treatment modality. As in any excision of head and neck tumors, the persistance of tumor at the surgical margins influences the outcome. One of the frequent criticisms of endoscopic resection is that the laser use makes interpretation of the surgical margins difficult due to the thermal effect. The goal of this study is to assess the reliability of frozen section after laser excision in locally advanced tumors. Methods The charts of patients with T2 and T3 tumors, who underwent TLM between January 2000 and 2008, using the CO2 laser AcuBlade system were reviewed. Frozen section margin results obtained during TLM were compared with margins after formalin fixation. Results Sixty-seven patients fulfilled the inclusion criteria. 20 had supraglottic tumors, 22 had oral cavity tumors, 13 had oropharyngeal tumors and 12 had hypopharyngeal tumors. Fifty-nine had no prior treatment, seven had prior radiation therapy and one had prior open surgery. The mean number of frozen margins per surgery was 4. Histological examination on the formalin-fixed tissue confirmed frozen section in 97% of the cases. In 3% of the frozen sections, the diagnosis of invasive carcinoma was missed. None of these patients had significant locoregional disease progression. Conclusion Frozen section analysis of margins is reliable during TLM when performed by an experienced team. It enables a one-stage approach reducing the need of a planned second procedure.

Texte intégralRésumé :
Metric learning based methods have attracted extensive interests in recommender systems. Current methods take the user-centric way in metric space to ensure the distance between user and negative item to be larger than that between the current user and positive item by a fixed margin. While they ignore the relations among positive item and negative item. As a result, these two items might be positioned closely, leading to incorrect results. Meanwhile, different users usually have different preferences, the fixed margin used in those methods can not be adaptive to various user biases, and thus decreases the performance as well. To address these two problems, a novel Symmetic Metric Learning with adaptive margin (SML) is proposed. In addition to the current user-centric metric, it symmetically introduces a positive item-centric metric which maintains closer distance from positive items to user, and push the negative items away from the positive items at the same time. Moreover, the dynamically adaptive margins are well trained to mitigate the impact of bias. Experimental results on three public recommendation datasets demonstrate that SML produces a competitive performance compared with several state-of-the-art methods.

Abstract Objectives This study aimed to survey dentists in Germany to identify their favored materials for the fabrication of tooth-supported single crowns (SCs) depending on the location of the abutment teeth and the preparation margin. Materials and methods The survey included questions regarding demographic characteristics of dentists/their dental practice and preferred restorative materials for the fabrication of SCs for abutment teeth 16, 11, 34, and 36 with either supra- or subgingival preparation margins. Results Between August 2019 and February 2020, 721 dentists participated in the survey; responses from 33 dentists were excluded from data analysis because the dentists did not work in Germany or provided less than one fixed dental prosthesis/month. Dentists favored ceramic materials independent of the location of the abutment tooth and preparation margin (56.6–92.2%). CAD/CAM resin composites or full metals were preferred by only a few participants. A significantly higher proportion of dentists recommended porcelain fused to metal for subgingival preparation margins than for supragingival margins (p < 0.001). Characteristics of dentists/dental practices influenced a single scenario (11 subgingival) that was dependent on the dentist’s time since graduation. When asked to specify the ceramic materials, numerous participants wrote a free response (5.7–7.8%) or did not answer (0.7–4.8%). Conclusions Dentists in Germany selected restorative materials for SCs depending on the clinical scenario. Since numerous dentists did not specify the ceramic materials, postgraduate information and education might help to extend expertise. Clinical relevance The results of this survey provide insight into the favored materials of dentists for the fabrication of tooth-supported SCs.

Introduction. The evaluation of the trimming surfaces (TS) of tissue blocks from frozen sections may serve as a supplementary examination tool for the intraoperative determination of resection margins of breast cancer specimens. This study aimed at the investigation of the feasibility and reliability of this technique, which has been described only very rarely in literature. Methods. Two observers assessed digital images from TS obtained from 57 resection margins. Findings were correlated with the diagnosis of the frozen section (FS) alone and the final diagnosis on formalin-fixed paraffin-embedded (FFPE) material. Results. The determination of the resection margin on TS was estimated as feasible for all cases. Interobserver congruence rate for TS was 96% (κ = 0.81), which was lower compared with FFPE (100%, κ = 1.0) but superior to FS (89%, κ = 0.67). Intraobserver congruence of the 2 reviewers was 96.5% and 93.0% between TS and FFPE, and 91.1% and 92.5% between FS and FFPE, respectively. The combination of both intraoperative consultation techniques showed similar congruence but a slight improvement for the sensitivity (0.75 to 0.875) for the diagnosis of tumor at the resection margin in FFPE for Reviewer 1 but was unchanged for Reviewer 2. Conclusion. The additional evaluation of TS can be a helpful additional tool for intraoperative margin assessment of breast cancer specimens, in particular, when processing artifacts of FS are encountered.

ABSTRACT It is common in business analyses to invoke different efficiencies generated by scale. Growth is associated with declining average costs/sales and rising profit margins. Factors cited include the relatively fixed nature of some costs, increased bargaining power, and network effects. We investigate how different cost lines evolve for a sample of U.S. firms after their IPO. To our surprise, costs/sales do not generally decline and margins do not increase, even during the early years when growth is highest. We observe similar results for other samples of domestic and overseas firms, both public and private. We explore possible explanations for our results and discuss implications, especially for cost allocation and financial projections. JEL Classifications: G30; M13; M21; M41.

Background: The treatment of cutaneous malignant melanoma of the face presents a challenge to ensure eradication of disease with maximum preservation of tissue. Mohs micrographic surgery provides a means for histologically controlled removal of malignant melanoma. Objective: This study evaluates the efficacy of Mohs micrographic surgery, at a single institution, for the treatment of facial melanoma and assesses the accuracy of margin control by frozen section techniques. Methods: Ninety-seven patients with biopsy-confirmed melanoma in situ or invasive melanoma of the face were treated by Mohs micrographic surgery over a 6-year period. In 25 patients, tissue margins defined as negative for melanoma at the time of frozen section were re-evaluated on permanent section histology of formalin-fixed, paraffin-embedded tissue. Results: Ninety-two of 97 patients had followup information available (8–72 months; mean 33 months). There were no cases of local recurrence. Eighty-nine of the 92 patients were alive and well with no evidence of disease. One patient died of metastatic melanoma. In situ or invasive melanoma was not identified on permanent sections of 117 tissue margins which had been interpreted as negative on frozen section. Conclusion: Mohs micrographic surgery appears to be an effective treatment for facial melanomas. Our study showed complete correlation between frozen section tissue margins and permanent section controls.

Texte intégralRésumé :
ABSTRACTMetal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the crown margins. This article describes a galvanic gold-plating technique, which is used to minimize corrosion and improve the esthetics of metal ceramic restorations fabricated with Cr-Co base metal alloys. This technique involves the deposition of a 6 μm to 8 μm 24 K gold layer directly onto the Cr-Co cast prosthesis framework. The technique improves metal surface properties, making them more biocompatible and usable, however, requires additional equipment and experienced laboratory technicians. Clinical studies should be performed to corroborate the long term success of this technique.

Texte intégralRésumé :
Background/Aim. In colon and rectal cancer surgery, resection is considered radical when circumferential, proximal and distal resection margins are without the presence of tumor cells. Concept of total mesorectal excision in rectal surgery involves complete removal of the tumor with mesorectal fascia which surrounds lymph nodes, lymphatics and blood vessels. The aim of this study was to determine whether laparoscopic approach provides all parameters of oncological radicality as open surgery of colorectal cancer. Methods. The study included 122 patients with carcinoma of colon and rectum, divided into two equal groups: patients operated on by laparoscopic and those operated on by open approach. In colon surgery we analyzed proximal and distal resection margins, and the number of removed lymph nodes, and in rectal surgery: proximal, distal and circumferential resection margins, and the number of removed lymph nodes. Results. Both groups were comparable in age, sex, American Society of Anesthesiologists (ASA) score, tumor localization, tumor size, and type of surgical operation performed. According to localization of the tumor, the most commonly performed operation was anterior resection of the rectum (60.7% vs. 59%). There was no case of the tumor involvement of the distal margin. Average proximal distance from the tumor on the fixed specimen was 100 vs. 120 mm with statistical significance (p < 0.001). Distal margins were not significantly different, 40 mm in both groups (p = 0.143). In two cases we had circumferential resection margin (CRM) of 1 mm (7.7%) in the laparoscopic group, and in three cases operated conventionally CRM was 1 mm (8.8%). The average number of removed lymph nodes was 15 vs. 16, respectively. Length of hospital stay for patients assigned to the laparoscopic surgery was significantly shorter than for patients operated on by the open approach. Concerning postoperative complications, no significant difference was found between groups. The overall postoperative morbidity was 18% vs. 21.3%, respectively. Conclusion. With laparoscopic approach it is possible to provide all parameters of oncological radicality similarly to the open surgery of colorectal cancer.

Texte intégralRésumé :
BACKGROUND: The replacement of missing teeth with fixed partial dentures is largely dependent upon the health and stability of the surrounding periodontal structures. FPDs are often prepared on vital teeth as abutments. Esthetic materials have become popular in fixed prosthodontics today.
AIM: The present study aimed to assess the long term effect and tissue responses of various types of fixed partial prosthesis placed on vital abutment teeth on the periodontal parameters both clinically and radiographically.
MATERIALS AND METHOD: Following ethical committee approval, the study group comprised of 87 abutment teeth in 41 systemically healthy patients (24 males and 17 females) aged between 18 – 45 years who had received 3 unit fixed prosthesis(IPS empress, PFM or zirconia), having equigingival margins using vital teeth as abutments. The following parameters were assessed at the time of bridge placement and 1 year follow up – CAL, Probing depth, Distance between CEJ/ cervical crown margin and alveolar crest of the abutment teeth(radiograph).
RESULTS: Statistical analysis carried out by SPSSV22 software revealed significant changes in clinical parameters with IPS empress and radiographic parameters with PFM and Zirconia from time of bridge placement till the 1 year follow up.(P<0.05).
CONCLUSION: There seemed to be favorable responses of the periodontal tissues to the various esthetic materials used on vital abutments of FPDs.

Texte intégralRésumé :
This paper aims to investigate the relationship between current ratio, earnings to price, net profit margin and stock returns in İstanbul Stock Exchange over the period 2008-2016 by employing panel data analysis. Due to the existence of heteroskedasticity, cross sectional dependence and autocorrelation in sample data, two-way fixed effects model is estimated by robust estimators. Both Parks-Kmenta and Beck-Katz methods are conducted to check whether the results are consistent or not. According to Park-Kmenta estimation model, the results show that earnings to price and net profit margin are significant to explain stock returns in İstanbul Stock Exchange while current ratio is found insignificant. Moreover, the test based on Beck-Katz model produces the similar results. Earnings to price and net profit margin are strong determinants of stock returns in Istanbul Stock Exchange. Stocks with higher E/P ratios and profit margins generate higher returns for the next period.

Texte intégralRésumé :
The purpose of this paper was to investigate, by means of marginal adaptation and fracture strength, three different types of single retainer posterior fixed partial dentures (FPDs) for the replacement of a missing premolar. Two-unit cantilever FPDs were fabricated from composite resin, feldspathic porcelain, and fiber-reinforced composite resin. After luting procedures and margin polishing, all specimens were subjected to a Scanning Electron Microscopic marginal evaluation both prior to and after thermomechanical loading with a custom made chewing simulator comprising both thermal and mechanical loads. The results indicated that the highest score of marginal adaptation, that is, the closest score to 100% of continuous margins, at thetooth-composite resininterface was attained by the feldspathic porcelain group (88.1% median), followed by the fiber-reinforced composite resin group (78.9% median). The worse results were observed in the composite resin group (58.05% median). Fracture strength was higher in feldspathic porcelain (196N median) when compared to resin composite (114.9 N median). All the fixed prostheses made of fiber-reinforced composite resin detached from the abutment teeth before fracturing, suggesting that the adhesive surface's retainer should be increased.

Texte intégralRésumé :
e18538 Background: The local recurrence rate of oral squamous cell carcinomas (OSCC) hardly decreases despite the best possible treatment. Partly, this is caused by the presence of (pre)malignant cells in the surrounding tissue, which can develop into a new malignancy in time. Histological recognition of these cells in resection margins appears to be difficult during routine practice. The aim of this study was to determine whether or not the presence of immune cells in OSCC resection margins may predict the development of a recurrence in these patients. Methods: Thirty-four patients with firstly diagnosed, radically resected primary OSCC with histopathological confirmed tumor-free margins (treated between 1993 and 2003) were included. Nine patients out of the 34 patient developed a locoregional recurrence within 5 years. Formalin-fixed paraffin-embedded tissue sections of 34 resection margins were subjected to immunohistochemistry for CD45, CD3, CD4, CD8, PD-L1 and PD-1 expression in immune cells, after which a quantitative analysis of the largerst distribution of CD45-, CD3-, CD4-, CD8-, PD-L1 and PD-1 positive lymphocytes on each resection margin has been photographed. The highly immunostained surface in relation to the total surface has been measured up to 100μm below the squamous epithelium. This analysis has been performed using QWin software (Leica). All data were analyzed using GraphPad Prism (version 7.05 for Windows, GraphPad Software, La Jolla California USA, www.graphpad.com). Results: Only CD3 and CD8 had a moderate correlation (Spearman = 0.68). A high expression of CD45 (≥7.7% ) and CD4 (≥5,4%) was strongly correlated with a worse disease-free survival (p = 0.0054 and p < 0.001, respectively), as was a low CD3 expression (≤5,9%) (p = 0.0211). PD-L1 and PD-1 expression analysis did not show a significant association with recurrence risk. Conclusions: A high amount of CD45-, and CD4- and a low amount of CD3-positive immune cells in OSCC resection margins may predict local recurrence.

Abstract. The South Atlantic rift basin evolved as branch of a large Jurassic-Cretaceous intraplate rift zone between the African and South American plates during the final breakup of western Gondwana. While the relative motions between South America and Africa for post-breakup times are well resolved, many issues pertaining to the fit reconstruction and particular the relation between kinematics and lithosphere dynamics during pre-breakup remain unclear in currently published plate models. We have compiled and assimilated data from these intraplated rifts and constructed a revised plate kinematic model for the pre-breakup evolution of the South Atlantic. Based on structural restoration of the conjugate South Atlantic margins and intracontinental rift basins in Africa and South America, we achieve a tight fit reconstruction which eliminates the need for previously inferred large intracontinental shear zones, in particular in Patagonian South America. By quantitatively accounting for crustal deformation in the Central and West African rift zone, we have been able to indirectly construct the kinematic history of the pre-breakup evolution of the conjugate West African-Brazilian margins. Our model suggests a causal link between changes in extension direction and velocity during continental extension and the generation of marginal structures such as the enigmatic Pre-salt sag basin and the São Paulo High. We model an initial E–W directed extension between South America and Africa (fixed in present-day position) at very low extensional velocities until Upper Hauterivian times (≈126 Ma) when rift activity along in the equatorial Atlantic domain started to increase significantly. During this initial ≈17 Myr-long stretching episode the Pre-salt basin width on the conjugate Brazilian and West African margins is generated. An intermediate stage between 126.57 Ma and Base Aptian is characterised by strain localisation, rapid lithospheric weakening in the equatorial Atlantic domain, resulting in both progressively increasing extensional velocities as well as a significant rotation of the extension direction to NE–SW. From Base Aptian onwards diachronous lithospheric breakup occurred along the central South Atlantic rift, first in the Sergipe-Alagoas/Rio Muni margin segment in the northernmost South Atlantic. Final breakup between South America and Africa occurred in the conjugate Santos–Benguela margin segment at around 113 Ma and in the Equatorial Atlantic domain between the Ghanaian Ridge and the Piauí-Ceará margin at 103 Ma. We conclude that such a multi-velocity, multi-directional rift history exerts primary control on the evolution of this conjugate passive margins systems and can explain the first order tectonic structures along the South Atlantic and possibly other passive margins.

The present state of the financial market in Ukraine determines a lack of funding for agricultural enterprises. The research aims to find internal sources of funding for the reproduction of fixed assets for agricultural enterprises. The calculation of the depreciation return index is a component of financial analysis of the efficient renovation investment use. It allows controlling its targeting and influence on enterprises in a financial aspect in order to provide a stable position of the enterprise`s investor.Implementation of economic and mathematical modeling using correlation and regression analysis verified a tight correlation between gross profit margins in agriculture and depreciation returns. For this purpose, general indexes were formed that is the primary value of fixed assets at the end of the year; the extent of their depreciation, depreciation and residual value of fixed assets at the end of the year, the average annual value of fixed assets, annual income, investment return and calculated gross profit and depreciation during 2001–2016 were determined. The results of the calculations showed that the funds saved through depreciation (renovation investments), and retained earnings are the financial resources for continuous renovation of fixed assets of agricultural enterprises. Also, attraction to internal reserves should have an impact on the increase of the agricultural enterprises’ profitability and should facilitate the increase of production volumes due to the implementation of innovations.

The research method used is a qualitative research method with a decriptive approach. Where data is the primary data obtained in the form of interviews with the parties concerned and secondary data in the form of data processing can be acconted for from a reliable source to conduct library research, interviews and internet. The result of this study found that setting the selling price on BRISyariah Murabahah Financing, BPRS Bumi Rinjani and UJKS El-Dinar that use the same basic price plus a profit margin. As for determining the profit margin that the bank sets its own and equally consider five factors determining the margin is the profit margin on everage Islamic Bank (Direct Competitor’s Market Rate/ DCMR), the interest rate the everage conventional banks (indirect Competitor’s Market Rate/ ICMR), the result of third-party funds (Competitive Expected Return for Investor/ ECRI), Overhead Cost, profit targets taking into account inflation and interest rate markets. In a benefit margin calculations using a flat (fixed).

ABSTRACT
This study aims to determine the effect of cash turnover, funding decisions, sales growth and company size on net profit margins at PT. Abcpower Group. This company is an electricity producer. The sample is 11 subsidiaries. Process data with EVIEWS 9.0 software. The Chow test is performed in testing panel data by selecting the fixed effect on the option panel›s cross section. The Haussman test is used to determine the most appropriate model to use is the fixed effect model. The results showed that cash turnover had an effect on the net profit margin. Funding decisions (DER) have no effect because existing funds are preferred to pay for operational costs. Sales growth has a significant positive effect on sales because the only way to increase current profit. The size of the company has no effect because many assets are not utilized optimally. The results of the study are expected to contribute to the company›s decision making. Future research can test other financial performance so that empirical evidence can be found regarding the relationship between the company›s financial components.

Texte intégralRésumé :
A quadruped (four-legged) robot locomotion has the potential ability for using in different applications such as walking over soft and rough terrains and to grantee the mobility and flexibility. In general, quadruped robots have three main periodic gaits: creeping gait, running gait and galloping gait. The main problem of the quadruped robot during walking is the needing to be statically stable for slow gaits such as creeping gait. The statically stable walking as a condition depends on the stability margins that calculated particularly for this gait. In this paper, the creeping gait sequence analysis of each leg step during the swing and fixed phases has been carried out. The calculation of the minimum stability margins depends upon the forward and inverse kinematic models for each 3-DOF leg and depends on vertical geometrical projection during walking. Simulation and results verify the stability insurance after calculation the minimum margins which indicate clearly the robot COG (Center of Gravity) inside the supporting polygon resulted from the leg-tips.
