While many philosophers of religion are familiar with the reconciliation of grace and freedom known as Molinism, fewer by far are familiar with that position initially developed by Molina’s erstwhile rival, Domingo Banez (i.e., Banezianism). My aim is to clarify a serious problem for the Banezian: how the Banezian can avoid the apparent conflict between a strong notion of freedom and apparently compatibilist conclusions. The most prominent attempt to defend Banezianism against compatibilism was (in)famously endorsed by Reginald Garrigou-Lagrange. Even if it were true that freedom does not require alternative possibilities, Banezians have a grounding problem.

Iron Storage Protein

The molecular structure of the iron-storage protein, ferritin, is becoming known in ever finer detail. The 24 apoferritin subunits (MW ca. 20,000) have a 2:1 axial ratio and are polymerized with 4:3:2 symmetry to form an outer shell surrounding a variable amount of microcrystalline iron, Recent x-ray diffraction results indicate that the projected outline of the native molecule has a quasi-hexagonal shape when viewed down the 3-fold axes of symmetry, and a quasi-square shape when looking down the 4-fold axes. To date, no electron microscope study has reported observing anything other than circular profiles, which would indicate that ferritin is strictly spherical. The apparent conflict between the "hollow sphere" of electron microscopy (E.M.) and the "truncated rhombic dodecahedron" of x-ray diffraction could reflect the poorer effective resolution of E.M. coming from radiation damage, staining, drying, etc. The present study investigates the detailed shape of individual ferritin molecules in order to search for the predicted aspherical profiles and to interpret the nature of this apparent contradiction.

Apparent Conflict

Why is education policy so contentious? Do conflicts over specific issues in schooling have anything in common? Are there general principles that can help us resolve these disputes? In this book the authors find the source of many debates over schooling in the multiple goals and internal contradictions of the national ideology we call the American dream. They also propose a framework for helping Americans get past acrimonious debates in order to help all children learn. The American Dream and the Public Schools examines issues that have excited and divided Americans for years, including desegregation, school funding, testing, vouchers, bilingual education, multicultural education, and ability grouping. These seem to be separate problems, but much of the contention over them comes down to the same thing--an apparent conflict, rooted in the American dream, between policies designed to promote each student's ability to pursue success and those designed to insure the good of all students or the nation as a whole. The authors show how policies to promote individual success too often benefit only those already privileged by race or class, and too often conflict, unnecessarily, with policies that are intended to benefit everyone. The book also examines issues such as creationism and Afrocentrism, where the disputes lie between those who attack the validity of the American dream and those who believe that such a challenge has no place in the public schools. At the end of the book, the authors examine the impact of our nation's rapid racial and ethnic transformation on the pursuit of all of these goals, and they propose ways to make public education work better to help all children succeed and become the citizens we need.

Abstract Background According to the Ministry of Health in Cyprus, since 2009, every year more than 3.000 new incidents with neoplasm are diagnosed. The National Health System (NHS) of Cyprus aims to offer adequate health services, comparing them with European Union standards. However, it is lacking a Positron Emission Tomography-Computed Tomography (PET/CT) unit. The present study aims to examine whether an investment by the Cyprus NHS of a PET/CT unit can be financially sustainable. Methods A financial analysis of the operating revenues and expenses of a departmental PET/CT with F18-FDG was performed taking into consideration all related parameters. A detailed estimation of the unit's operation expenses (PET/CT unit supply, overheads, salaries, etc.) and incomes was produced for a 15-year period. This initial scenario was not financially viable and therefore two alternatives are also examined. Results After performing a detailed analysis and projection for the evaluation of the feasibility study in the initial scenario, the overall outcome is estimated negative deriving to a €2,2 million losses in the cumulative results by 2035. The second scenario concluded that the required number of incidents to reach a neutral cash flow after a 15-year period should increase from 8.971 to 23.430. The third scenario reached the conclusion that a parallel investment to the purchase of the PET/CT unit by installing a cyclotron unit in the Cypriot NHS provides cumulative results positive of €1,7 million for the PET/CT, in the same period, that can finance the largest part of the €2,5 million required for the installation of the cyclotron unit. Conclusions Our findings show that an investment of a sole PET/CT unit is not a financially viable. Alternative possibilities such as usage of a PET/CT operated by the private sector or supporting patients to travel to another country are within the economic terms recommended. Key messages From a financial viewpoint, the scenario of investing in a PET/CT unit by the Cyprus NHS is not viable. Examining alternative options for patients in need of a PET/CT unit, where the initial investment cost for the state is not financially viable.

This article presents the problems of powering wireless sensor networks operating in the structures of the Internet of Things (IoT). This issue was discussed on the example of a universal end node in IoT technology containing RFID (Radio Frequency Identification) tags. The basic methods of signal transmission in these types of networks are discussed and their impact on the basic requirements such as range, transmission speed, low energy consumption, and the maximum number of devices that can simultaneously operate in the network. The issue of low power consumption of devices used in IoT solutions is one of the main research objects. The analysis of possible communication protocols has shown that there is a possibility of effective optimization in this area. The wide range of power sources available on the market, used in nodes of wireless sensor networks, was compared. The alternative possibilities of powering the network nodes from Energy Harvesting (EH) generators are presented.

Apparent Conflict

The controversy which exists at the present time between the figures 125 and 170 kcal./g.- atom for the latent heat of sublimation of carbon into monatomic vapour in the ground state originates largely from the neglect to take into consideration the energy required to raise the carbon atoms from the ground ( 3 P ) state to the lowest tetravalent ( 5 S ) electronic configuration corresponding to that in which it is normally found in chemical combination. Consideration of the energies of removal of a hydrogen atom from the methane and ethane molecules and of the energies of reorganization of the resulting radicals leads to the figure 190 ± about 10 kcal. for L 2 , the heat of sublimation into free atoms in the 5 S state. This in turn leads to a satisfactory and unambiguous assignment of values to bond energies (as distinct from dissociation energies) which can now be expressed with an uncertainty of not more than a few kcal. In the light of the valency distinction there remains no sound evidence to maintain the higher value put forward for L 1 and 125 kcal. is unquestionably of the right order. There are strong indications that an earlier estimate of 100 kcal. for the energy level of the 5 S state above the 3 P (ground) state is about 50 % in excess of the true value. The necessity for establishing this branch of thermochemistry on a sound theoretical and experimental footing has long been a very obvious need. The scheme here suggested reconciles points hitherto in apparent conflict, and brings virtually all established experimental knowledge into alignment.

This paper is a defense of traditional compatibilism. Traditional compatibilism is, roughly, the view that (a) free will is essential to moral responsibility, (b) free will requires alternative possibilities of action, or alternatives for short, and (c) moral responsibility is compatible with determinism. Traditional compatibilism is a version of the traditional theory of free will. According to the traditional theory, a person S performed an action a freely only if S could have done otherwise, that is, only if S had alternatives. The traditional theory is often contrasted with the source theory: S performed a freely only if S was the source of a (McKenna 2001; Pereboom 2003). One may adopt a combined view of free will that sanctions both the traditional and source theories (Kane 1996, 72-3; van Inwagen 1983). As I use the terms ‘source theorist’ and ‘traditional theorist,’ the former refers to folks who accept the source theory and reject the traditional theory; the latter refers to folks who accept the traditional theory whether or not they accept the source theory.
