Colour Appearance

Scaling experiments presented at ECVP 1996 (Ovenston and Whittle, 1996 Perception25 Supplement, 16) demonstrated the importance of the background chromaticity in setting subjective equal-interval colour scales along the L(-M)-cone and S-cone axes of Macleod - Boynton isoluminant chromaticity space. In the current experiments we also investigate colour scaling but around circles centred on different background chromaticity points. This is done in a logarithmic version of the MacLeod - Boynton diagram, which is much closer to an equal-subjective-interval diagram than the linear version. However, colour circles set with even geometrical spacing in the log diagram do not appear to have even subjective spacing. Preliminary results show that setting hue to even subjective spacing is a convenient and powerful method for studying the role of constant-cone-excitations and opponent-colour axes in determining hue.

SummaryIn 1966, a National Survey on Fecundity and Fertility was organized in Belgium. Approximately 3000 married women under 41 years of age and living with their husbands were interviewed and asked about their reproductive histories. The present paper records the sociobiological aims and methods and some preliminary results of this survey. The aims were to:(1) study the influences of contraception on human needs and qualities, in this case mainly potential fecundity;(2) study the influence of attempts to increase the potential fecundity level in modern society on fecundity gene frequencies;(3) study the influences of the overall socio-cultural environment on fecundity and fertility variables with particular reference to differences in social status in Western society;(4) analyse the role of social assortment of fecundity and fertility variables on the biological structure, and possibly the composition, of modern populations.A relatively large, but far from complete body of data has been collected on a number of individual fecundity and fertility variables, on the medical processes employed to increase fecundity, on contraception, and on a number of conventional sociological and demographic variables.The principles underlying the present approach to the study of fecundity are explained, and a few preliminary results for one of the general fecundity classifications are shown.The information collected on contraception has been qualitatively analysed and a correction and evaluation method is described. Data on the use of the different contraceptive methods show that substantial sections of the Belgian population are limiting their family size in a way which is inefficient, from both sexual and familial standpoints.

Preliminary Results

Introduction: Chronic prostatitis displays a variety of symptoms (mainly local pain exhibiting variability in origin and intensity). The purpose of this article is to briefly present the preliminary results of our study examining the role of phytotherapeutic agents in the treatment of chronic prostatitis patients. Materials and methods: The study included in total fifty-six consecutive patients who visited the outpatient department. Subjects were randomized into two groups. Subjects in the first group (28 patients) received prulifloxacin 600 mg for 15 days, while subjects in the second group (28 patients) received prulifloxacin 600 mg for 15 days and Serenoa repens extract for 8 weeks. The response was tested using laboratory and clinical criteria. Results: We found statistically significant differences between the two groups regarding pain regression and no statistically significant regarding bacterial eradication. Moreover however while sexual dysfunction improvement was equally achieved in both groups, improvement of urinary symptoms was more evident in the 2nd group especially after the completion of the antibiotic treatment. Conclusions: Serenoa repens extract for 8 weeks seems to improve prostatitis related pain. Further randomized, placebo-controlled studies are needed to substantiate safer conclusions.

Insight Into

With the concept of Urban Agriculture (UA) growing in popularity, more cities and towns are exploring opportunities to enable the practice and transform neglected spaces into havens for produce. This chapter provides an insight into one such town, Todmorden and its Incredible Edible movement, located in the heart of England. This chapter adopts a qualitative approach to critically exploring the IET movement and to understand its impact on Todmorden. We engaged with key actors and the public in order to ascertain views towards the schemes, analysing the positives and negatives of the model. Findings revealed that the scheme has an overwhelmingly positive impact on the town, with social, environmental and economic benefits. Furthermore, it was made clear that IET is helping to create a more just food movement in Todmorden, particularly through its free for all philosophy. However, some negatives were also highlighted during the course of the research, predominately around maintenance issues and a lack of perceived inclusivity in parts. Overall, the scheme was highly valued and seen as a powerful method for growing the wider UA movement; recommendations centred on further replicating the model and helping local food to prosper in similar locations globally.

Dimensional Picture

Three-dimensional computerized imaging is a new modality of radiological imaging. This new technique transforms the two-dimensional slices of bi-plane CT into a three-dimensional picture by a computer’s monitor adjusted to the system. This system enables the physician to rotate the angle of viewing of the desired region to any desired angle. Moreover, this system can delete certain features of different densities from the picture, such as silicone implants, thus improving visualization. Our preliminary results using this technique are presented. The advantages, pitfalls, and suggested future applications of this new technique in hand surgery are discussed.
