Abstract This paper studies the impact of inflation on income taxes in Sweden, UK, and United States during world wars. As tax reforms were rising top marginal rates reducing exemption thresholds, extraordinary levels eroded real value exemptions, brackets, deductions. The micro-simulation actual alternative scenarios shows that made less progressive, particularly Sweden World War I UK II. Neve...
Background and Aims: Marginal adaptation is important for the long-term success of full-coverage restorations. Preparation design is one of the important factors influencing the marginal integrity. Therefore, the purpose of this study was to compare the effect of radial shoulder and chamfer finish line designs on the marginal adaptation of all-ceramic Cercon restorations.Materials and Methods: ...
Background and Aims: Marginal gap measurement in all ceramic restorations they are of fundamental important for the successful used. As some studies led to contradiction results, yhe aim of this study is to compare marginal gap restorations between 4 kinds of ceramic restorations Inceram, IPS-e.max Press, Zirconia (CAD/CAM) and PFM. Materials and Methods: In this In-vitro experimental research...
سابقه و هدف: یکی از مهم ترین شاخص های مقبولیت کلینیکی و دوام رستوریشن های ریختگی تطابق مارجینالی آنهاست. عدم وجود آن به اکسپوژر لایه سمان، حل شدن آن، تجمع پلاک باکتریال، عود پوسیدگی و التهاب بافت های لثه منجر می گردد. هدف از انجام این تحقیق ارزیابی تاثیر نوع خط خاتمه تراش بر میزان marginal discrepancy بود. مواد و روش ها: در این مطالعه تجربی آزمایشگاهی، سه عدد دای فلزی به روش شبیه سازی تهیه، یکی...
Introduction: Marginal fit is a key factor for long term clinical success through any dental restorations. Poor marginal adaptation causes cement dissolution. This can lead to dental caries, gingival irritation, periodontal diseases, and finally treatment failure. The aim of this study was measurement and comparison of marginal gap quantities in metal ceramic and all ceramic dental restorations...
We develop a theory linking “misallocation,” i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion MPK depends on (i) heterogeneity firm-level risk and (ii) the magnitude premia. Stock market-based measures imply that considerations explain about 25% among US firms rationalize large persistent component MPK, consistent with micro-level data. Time-varying prem...
objectives : marginal adaptation is important for long-term success of full-coverage restorations. the aim of this study was to determine the effect of porcelain firing cycle and different thicknesses of ips e.max core on marginal accuracy of all-ceramic restorations. materials and methods : a standard stainless steel die with 0.8 mm classic chamfer finish line and 10° taper was used in this in...
