We describe recent advances in the empirical analysis of insurance markets. This new research proposes ways to estimate individual demand for insurance and the relationship between prices and insurer costs in the presence of adverse and advantageous selection. We discuss how these models permit the measurement of welfare distortions arising from asymmetric information and the welfare consequenc...

Affinity-chromatographic purification of the folate-binding protein from whey of cow's milk results in the removal of a heat-resistant cofactor that is important in high-affinity folate binding (Biochim, Biophys. Acta 579: 479, 1979). Thus a shift from negative to positive cooperativity occurred in the presence of cofactor (Biochim, Biophys. Acta 579: 479, 1979). We demonstrate the presence of ...

Many believe that “big data” will transform business, government and other aspects of the economy. In this article we discuss how new data may impact economic policy and economic research. Large-scale administrative datasets and proprietary private sector data can greatly improve the way we measure, track and describe economic activity. They also can enable novel research designs that allow res...

سایندگی از جمله ویژگی های مهم در پروژه های حفاری در آبرفت ها می باشد. این پدیده سبب سایش و خوردگی ابزار حفار و قطعات ماشین های حفاری و افزایش هزینه ها و کاهش قابل توجه در راندمان فرآیند حفاری می گردد. لذا در پروژه های حفاری که پتانسیل سایندگی در دستگاههای حفاری وجود دارد، بررسی و مطالعات اولیه جهت تعیین میزان سایندگی، نقش بارزی را در تخمین هزینه ها و اتخاذ روشهای مناسب برای جلوگیری از سایش خواه...

Introduction: Stenotrophomonas maltophilia is an opportunistic gram-negative rod emerging as a cause of various multidrug-resistant infections. Case Report: We report a case of implantable cardioverter-defibrillator (ICD) pocket infection caused by S. maltophilia in an 85-year-old male. The patient recovered after ICD removal and antimicrobial therapy with ceftazidime. Conclusion: As ICD implan...

The amounts of 540 nm light and 660 nm light that when mixed result in a yellow (neither reddish nor greenish) percept remain in constant ratio, regardless of the total retinal illumance level of the mixture. A similar result holds if the mixture is superimposed upon a very dim 660 nm adapting field, except that a larger proportion of 540 nm light is required than in the dark (contrary to an ef...
