Racism is a scourge which has plagued societies for centuries. Its root cause can be found in the fear of others. Some authors have considered it as a mental disorder in its more severe forms. We approach it from a novel and highly actionable angle by comparing it to a transmissible disease, candidiasis, with which racism holds many essential similarities that we outline in details. We also suggest various ways to eradicate and mitigate racism through practical action plans.

Abstract This article sets out key contributions to the long-running debate about mental disorder from the ordinary language philosophy of the ‘Oxford School’. The distinction between definition and use of concepts underpinning ordinary language philosophy reframes the debate as a debate not just about mental disorder but about disorder in general, bodily as well as mental. The field work of ordinary language philosophy (focusing on the use of concepts as a guide to their meanings) shows that, attempts at elimination notwithstanding, there is an essential evaluative element in the meaning of disorder, bodily as well as mental. The concept of disorder in the debate thus reframed presents a double challenge for analysis: to explain why disorder has evaluative connotations used of mental conditions but descriptive connotations used of bodily conditions. Philosophical value theory, derived by applying ordinary language philosophy to the language of values, provides a rich resource of ideas for meeting this double challenge. It meets the double challenge at the level of theory by allowing both aspects of the double challenge of disorder to be derived from a logical property that disorder shares with all other value terms. It meets the double challenge at the level of practice by supporting the development of a new approach to working with values alongside evidence in healthcare called values-based practice. Ordinary language philosophy, notwithstanding these several contributions, is no panacea. It helps us to make a start, no more and no less, in understanding mental disorder.

The original style and contents of Nathaniel Lee’s production have often been interpreted as indicative of the author’s alleged mental illness. This contribution proposes a new approach to Lee’s works, suggesting that the tragedy Brutus (1680), which contains a sort of nosology of alterations in thought and behaviour, is a liminal text on the border between literature and medical treatise. Lee appropriates the scientific discourse of his time not only to question recent notions of mental disorder, but also to articulate a reflection on the condition of power in the political world.

AbstractUse of network models to identify causal structure typically blocks reduction across the sciences. Entanglement of mental processes with environmental and intentional relationships, as Borsboom et al. argue, makes reduction of psychology to neuroscience particularly implausible. However, in psychiatry, a mental disorder can involve no brain disorder at all, even when the former crucially depends on aspects of brain structure. Gambling addiction constitutes an example.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

Immunoelectron microscopy of neoplastic lymphoma cells is valuable for precise localization of surface antigens and identification of cell types. We have developed a new approach in which the immunohistochemical staining can be evaluated prior to embedding for EM and desired area subsequently selected for ultrathin sectioning.A freshly prepared lymphoma cell suspension is spun onto polylysine hydrobromide- coated glass slides by cytocentrifugation and immediately fixed without air drying in polylysine paraformaldehyde (PLP) fixative. After rinsing in PBS, slides are stained by a 3-step immunoperoxidase method. Cell monolayer is then fixed in buffered 3% glutaraldehyde prior to DAB reaction. After the DAB reaction step, wet monolayers can be examined under LM for presence of brown reaction product and selected monolayers then processed by routine methods for EM and embedded with the Chien Re-embedding Mold. After the polymerization, the epoxy blocks are easily separated from the glass slides by heatingon a 100°C hot plate for 20 seconds.

The corrosion of copper and copper alloys in a marine environment is of great concern because of their widespread use in heat exchangers and steam condensers in which natural seawater is the coolant. It has become increasingly evident that microorganisms play an important role in the corrosion of a number of metals and alloys under a variety of environments. For the past 15 years the use of SEM has proven to be useful in studying biofilms and spatial relationships between bacteria and localized corrosion of metals. Little information, however, has been obtained using TEM capitalizing on its higher spacial resolution and the transmission observation of interfaces. The research presented herein is the first step of this new approach in studying the corrosion with biological influence in pure copper.Commercially produced copper (Cu, 99%) foils of approximately 120 μm thick exposed to a copper-tolerant marine bacterium, Oceanospirillum, and an abiotic culture medium were subsampled (1 cm × 1 cm) for this study along with unexposed control samples.

With the introduction of field-emission sources and “immersion-type” objective lenses, the resolution obtainable with modern scanning electron microscopes is approaching that obtainable in STEM and TEM-but only with specific types of specimens. Bulk specimens still suffer from the restrictions imposed by internal scattering and the need to be conducting. Advances in coating techniques have largely overcome these problems but for a sizeable body of specimens, the restrictions imposed by coating are unacceptable.For such specimens, low voltage operation, with its low beam penetration and freedom from charging artifacts, is the method of choice.Unfortunately the technical dificulties in producing an electron beam sufficiently small and of sufficient intensity are considerably greater at low beam energies — so much so that a radical reevaluation of convential design concepts is needed.The probe diameter is usually given by
