An Integrative Approach to Value‐Added Planning: From Community Needs to Local Authority Revenue

The concept of value‐added planning (as part of the Valuing Attractive Landscapes in the Urban Economy, INTERREG IVB North West Europe Project) is introduced in this paper to facilitate integrative planning, focusing on the benefits that use and non‐use green spaces can provide to an urban area. The aim is to stress the need to plan for, and protect, green spaces in urban areas by determining the economic values connected to the green spaces and relate that values to community benefit and local authority revenue. The paper identifies tools that can be used to determine the economic value of green spaces based on the environmental, social, and economic benefits. The first section (value) refers to the social value of green spaces as determined from the public perspective and introduces the workbench method as a tool to assist with participatory planning and capturing of the social benefits of green spaces. The second section (added) refers to the environmental benefits of green spaces and, by means of the Green Credit Tool, introduces ways to ensure the protection of the green resources in an area. The final section (planning) refers to the economic benefit of green space, bringing use values and non‐use values of green spaces together. The paper concludes with an integrative framework for value‐added planning, incorporating all the tools presented in the paper, capturing the social, environmental, and economic benefits of green spaces and relating it to community benefit and local authority revenue.     

Comparative pathology of endometrial carcinoma

A review is given of the comparative pathology of endometrial carcinomas regarding the incidence, the morphology, and the relation with endometrial hyperplasia. Compared to man, endometrial carcinomas in animals are fairly rare, except in rabbits, in cattle, and in a stock of Han: Wistar rats. In rabbits the endometrial carcinomas are mostly primary multiple and present in both horns. Histologically they are almost always adenocarcinomas. The histological structure can vary considerably with regard to the degree of differentiation. In cattle the endometrial carcinomas are mostly singular. Histologically they are mostly adenocarcinomas, often accompanied by formation of much dense fibrous tissue. In rats the endometrial carcinomas are mostly primary multiple adenocarcinomas. In man as well as in the rabbit and in the rat, relationships have been described between endometrial hyperplasia and endometrial carcinoma. It is striking that in the dog, a species in which endometrial hyperplasia very often occurs, endometrial carcinomas should be rare. The endometrial carcinoma in the rabbit as an animal model for human endometrial carcinoma is discussed extensively. In both species there are signs indicating relationships between endometrial carcinomas and sex hormones, especially oestrogens. The incidence in rabbits is very high. Endometrial carcinomas in rabbits can be transplanted subcutaneously in the same rabbit. They can also be cultured in vitro. Moreover the rabbit is a suitable species to study the progesterone/progesterone-receptor complex by determining the synthesis of the progesterone-induced protein uteroglobin which may be important in studying endometrial carcinomas. Uteroglobin is a good marker for a functional 'Progesterone-PR-DNA-mRNAug-Uteroglobin- System' (or PUG-System).(ABSTRACT TRUNCATED AT 250 WORDS)     

3-methylthiopropionaldehyde as precursor of dimethyl trisulfide in aged beers

Hop S-methylcysteine sulfoxide has previously been postulated as the precursor of dimethyl trisulfide (DMTS) in beers. The present data point to 3-methylthiopropionaldehyde, the Strecker aldehyde issued from methionine, as another potential precursor in aged beers. Spiking either fresh beer or wort before boiling leads in all cases to higher levels of DMTS after storage. Moreover, special malts with a high level of 3-methylthiopropionaldehyde also favor polysulfide synthesis. A higher pH should increase this onion-like off-flavor, whereas a low pH is unfortunately known to enhance the cardboard flavor of aged beers. 3-methylthiopropanol, issued from yeast reducing activity, can be considered as an additional DMTS source during aging.     

Factors of human chronic pain: an analysis of personality and pain reaction variables

Factor analysis of pain and personality test data obtained from 119 patients with chronic pain syndromes yields seven factors: four composed of personality measures, two involving different psychophysical pain measures, and one sex-related factor. The chief factors, comprising more than 50 percent of the total variance, are "interpersonal alienation and manipulativeness," "clinical pain intensity", and "pain endurance."     

Transplacental transmission of Bluetongue virus serotype 8 in ewes in early and mid gestation

The ability of Bluetongue virus serotype 8 (BTV-8) originating from the 2006 European outbreak to cross the ovine placenta during early and mid gestation was investigated in two separate experiments. In the first experiment, 16 ewes were infected with BTV-8 at 70-75 days gestation. The foetuses were collected at 18-19 days after infection (dpi). BTV-8 could be isolated from at least two organs of 19 out of 40 lambs and from 11 out of 16 infected ewes. In the second experiment, 20 BTV-8 infected ewes in early gestation (day 40-45) were euthanized at 10 days (10 ewes) or 30 days (10 ewes) after infection. The presence of BTV could be demonstrated in two foetuses from two ewes at 10 dpi and in 4 foetuses from four ewes at 30 dpi. The main pathological findings in the foetuses in mid gestation were meningo-encephalitis and vacuolation of the cerebrum. In the foetuses early at gestation, haemorrhages in various foetal tissues and necrosis and haemorrhages in the placentomes were found. These experiments demonstrate for the first time the presence of infectious BTV in lamb foetuses at different stages of gestation, combined with a difference in transmission rate depending on the gestation stage. The high transmission rate found at mid term gestation (69%) makes our model very suitable for further research into the mechanisms of transplacental transmission and for research into the reduction of this route of transmission through vaccination.     

Differences between spring wheat cultivars in tolerance to <Emphasis Type="Italic">Fusarium</Emphasis> seedling blight under organic field conditions

Use of Fusarium-infected seed for cereal crops results in a reduced plant density due to seedling blight. This is especially a problem in organic agriculture, for which currently no practical seed disinfection methods are available. In the present paper we investigated whether spring wheat cultivars differ in tolerance to seedling blight in vivo, whether the possible differences could be linked to cultivar differences in initial growth rates, and whether differences in weed infestation were related to differences in emergence. Seed six spring wheat cultivars (Melon, Lavett, SW Kungsjett, Epos, Pasteur, Thasos), containing three Fusarium infection levels were obtained and sown in two field experiments in 2006 and 2007 and in an outdoor pot experiment in 2007. Results indicated that the six spring wheat cultivars differed in their tolerance to seedling blight, and consequently in the percentage of emergence of their seeds. The relative levels of tolerance to seedling blight of the six cultivars were robust in the three experiments performed. No clear relationship between initial growth rates and tolerance was found. In our experiments, no early and homogenous weed pressure was present, but in the 2007 field experiment a relationship between initial seedling emergence and weed infestation after anthesis was determined. Based on the presented results we suggest that additional to resistance to Fusarium head blight (FHB), differences in tolerance to seedling blight should also be considered during selection of wheat cultivars for organic agriculture.     

Stimulation of gonadal and germ cell development in larval and juvenile carp (Cyprinus carpio L.) by homologous pituitary extract

The data presented show that in larval carp, gonadal size has increased distinctly after treatment with homologous pituitary extract (PE). Moreover, the precocious onset of primordial germ cell proliferation and of sex differentiation into male and female gonads was induced. Body weight of treated and control specimens did not differ significantly from each other throughout the experiment. Treatment of juvenile carp with homologous PE led also to an increase in gonadal size without concomitant increase in body weight. Induction of precocious spermatogenesis was observed too. GTH-levels in control and PE-treated carp were monitored by means of a homologous radioimmunoassay, showing that in PE-treated carp the GTH-level was distinctly elevated. The possible role of pituitary hormones in larval and juvenile gonadal development is discussed.     

ROUGH SHEATH2: a Myb protein that represses knox homeobox genes in maize lateral organ primordia

The regulation of members of the knotted1-like homeobox (knox) gene family is required for the normal initiation and development of lateral organs. The maize rough sheath2 (rs2) gene, which encodes a Myb-domain protein, is expressed in lateral organ primordia and their initials. Mutations in the rs2 gene permit ectopic expression of knox genes in leaf and floral primordia, causing a variety of developmental defects. Ectopic KNOX protein accumulation in rs2 mutants occurs in a subset of the normal rs2-expressing cells. This variegated accumulation of KNOX proteins in rs2 mutants suggests that rs2 represses knox expression through epigenetic means.
