The sulfur dioxide (SO2) cap and trade program established in the 1990 Clean Air Act Amendments is celebrated for reducing abatement costs ($0.7 to $2.1 billion per year) by allowing emissions allowances to be traded. Unfortunately, places with high marginal costs also tend to have high marginal damages. Ton-for-ton trading reduces emissions in low damage areas (rural) while increasing emission...

Objectives. The aim was to evaluate survival and success rates, soft tissue health, and radiographic marginal bone loss (MBL) of zirconia implants placed in the esthetic and posterior areas of the jaws and in association with multiple or single implant restorations after at least 6 months of definitive restoration. Material and Methods. 35 one-piece zirconium implants were utilized for single o...

Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics probably involved in gastric cancer incidence through activation of procarcinogens. North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds, including agricultural pesticides, are massively used. In this report, we quantitatively...

The marginal likelihood plays an important role in many areas of Bayesian statistics such as parameter estimation, model comparison, and model averaging. In most applications, however, the marginal likelihood is not analytically tractable and must be approximated using numerical methods. Here we provide a tutorial on bridge sampling (Bennett, 1976; Meng & Wong, 1996), a reliable and relatively ...

The marginal nucleus is a congregation of large cells in the lateral portion of the spinal cord and is found in a number of vertebrates including man and is prominent in reptiles. Recent studies suggest that these cells are mechanoreceptors that respond to stretching of the spinal cord, and are unique in that they are located within the central nervous system. Studies on the marginal nucleus in...

Nomadism is found mostly in marginal areas which support only relatively sparse populations, particularly in the arid and semi-arid regions of Africa and Asia. It is a traditional form of society that allows the mobility and flexibility necessary for relatively even use of vegetation over large areas of low quality rangeland. It also facilitates more social interaction than would be possible am...

purpose: the aim of this study was to evaluate the effect of two gingival finishing lines (90° shoulder and deep chamfer) on the marginal fitness of two types of full anatomic all-ceramic crowns; zirconia crowns (zikonzhan) and glass ceramic crowns (ips e-max cad) milled with cad/cam system. materials and methods: two dentoform teeth of left maxillary first molar were prepared with chamfer fini...

Todd Proebsting’s 1998 pronouncement that compiler optimisation research only results in marginal performance improvements was accompanied by the gloomy suggestion that perhaps researchers should spend their time in areas more likely to yield large performance gains, such as research into programmer productivity. This paper revisits Proebsting’s claims, and finds them to be optimistic.
