Are sulfurous soil amendments (S0, Fe(II)SO4, Fe(III)SO4) an effective tool in the restoration of heathland and acidic grassland after four decades of rock phosphate Fertilization?

This paper deals with the complex issue of reversing long-term improvements of fertility in soils derived from heathlands and acidic grasslands using sulfur-based amendments. The experiment was conducted on a former heathland and acid grassland in the U.K. that was heavily fertilized and limed with rock phosphate, chalk, and marl. The experimental work had three aims. First, to determine whether sulfurous soil amendments are able to lower pH to a level suitable for heathland and acidic grassland re-creation (approximately 3 pH units). Second, to determine what effect the soil amendments have on the available pool of some basic cations and some potentially toxic acidic cations that may affect the plant community. Third, to determine whether the addition of Fe to the soil system would sequester PO4− ions that might be liberated from rock phosphate by the experimental treatments. The application of S0 and Fe(II)SO4− to the soil was able to reduce pH. However, only the highest S0 treatment (2,000 kg/ha S) lowered pH sufficiently for heathland restoration purposes but effectively so. Where pH was lowered, basic cations were lost from the exchangeable pool and replaced by acidic cations. Where Fe was added to the soil, there was no evidence of PO4− sequestration from soil test data (Olsen P), but sequestration was apparent because of lower foliar P in the grass sward. The ability of the forb Rumex acetosella to apparently detoxify Al3+, prevalent in acidified soils, appeared to give it a competitive advantage over other less tolerant species. We would anticipate further changes in plant community structure through time, driven by Al3+ toxicity, leading to the competitive exclusion of less tolerant species. This, we suggest, is a key abiotic driver in the restoration of biotic (acidic plant) communities.

Downland, marsh, and weald: monastic foundation and rural intensification in Anglo-Saxon Kent

This paper takes a fresh look at the relationship between Christian conversion and economic change in Anglo-Saxon England, drawing upon new archaeological evidence from Kent. One of its primary aims is to exploit the archaeological record to provide a critical perspective on how these two processes may have related to one another, paying particular attention to previous assumptions concerning the role played by monastic institutions in the process of rural intensification in Anglo-Saxon England.

Passive Restoration in Biodiversity Hotspots: Consequences for an Atlantic Rainforest Lizard Taxocene

Long-term conservation in biodiversity hotspots depends on the recovery of communities in secondary forest fragments. In most cases, however, recovery strategies for these areas are based only on passive restoration. It is therefore necessary to determine the efficiency of such strategies. In this study, we assess the efficiency of passive restoration on a 567-ha 28-yr-old fragment of Atlantic Rainforest in Northeastern Brazil. We measured richness, composition, abundance and biomass of a lizard taxocene and also vegetation structure and availability of several microhabitat descriptors in 18 plots of this secondary forest. We then compared them with measures in 29 plots from two neighboring reference sites. Species richness, abundance, biomass and microhabitat descriptors availability inside the secondary fragment did not differ from reference sites. However, composition and vegetation structure showed small differences. Some forest specialist lizards, which should be a focus of conservation efforts in fragmented landscapes of the Atlantic Rainforest, were not found in the fragment and data indicate that this was not due to sampling or a lack of suitable habitat or microhabitat. In the presence of preserved source sites, passive restoration may be a cheap and effective way to recover lizard taxocenes of the Atlantic Rainforest. Some of the species may need to be re-introduced to accelerate the full recovery of original composition of lizard taxocenes in secondary Atlantic Rainforests.

Influence of Er:YAG laser on surface treatment of aged composite resin to repair restoration

The purpose of this study was to investigate the effect of Er:YAG laser on surface treatment to the bond strength of repaired composite resin after aged. Sixty specimens (n = 10) were made with composite resin (Z250, 3M) and thermocycled with 500 cycles, oscillating between 5 to 55A degrees C. The specimens were randomly separated in six groups which suffered the following superficial treatments: no treatment (GI, control), wearing with diamond bur (GII), sandblasted with aluminum oxide with 27.5 A mu m particles (GIII) for 10 s, 200 mJ Er:YAG laser (GIV), 300 mJ Er:YAG laser (GV), and 400 mJ Er:YAG laser (GVI), with the last 3 groups under a 10 Hz frequency for 10 s. Restoration repair was done using the same composite. The shear test was done into the Universal testing machine MTS-810. Analyzing the results through ANOVA and Tukey test, no significant differences were found (p-value is 0.5120). Average values analysis showed that superficial treatment with aluminum oxide presented the highest resistance to shear repair interface (8.91MPa) while 400 mJ Er:YAG laser presented the lowest (6.76 MPa). Fracture types analysis revealed that 90% suffered cohesive fractures to GIII. The Er:YAG laser used as superficial treatment of the aged composite resin before the repair showed similar results when used diamond bur and sandblasting with aluminum oxide particles.

Medhörning i studio

I denna uppsats undersöker jag hur musikerns prestation påverkas av medhörningen. Jag har inriktat mig på sångare och sånginspelning i studio. I undersökningen har jag använt mig av tre informanter som fick sjunga till fem olika mixar i medhörningen. Jag analyserade sedan deras intonering, rytmisering och sångstyrka. Resultaten av undersökningen blev att intoneringen till viss del påverkas av medhörningen, rytmiseringen och sångstyrkan påverkas i hög grad av medhörningen.

Sine ira et studio : En kvalitativ analys av institutionaliseringsprocessens konsekvenser inom den nypaganistiska rörelsen Church of All Worlds

Uppsatsen har för avsikt att undersöka hur den nypaganistiska, och i första hand nordamerikanska, rörelsen Church of All Worlds reagerar mot förändring och institutionalisering. För att förstå institutionaliseringsprocessens bakomliggande krafter och identifiera dess konsekvenser, är det övergripande syftet med uppsatsen att utifrån en fallstudie av Church of All Worlds undersöka hur organisationen under sina verksamhetsår förändrats i fråga om (1) förhållande till samhället, (2) ideologi, (3) organisatorisk struktur och (4) ledarskap. Utgångspunkten är att betrakta rörelsen som dels religiös och spirituell, dels organisatorisk och ekonomisk, varför uppsatsen lutar sin teoribildning mot både religions- och samhällsvetenskapen och mot organisationsteorin. Som samhälleliga samt organisatoriska faktorer till Church of All Worlds institutionalisering finner vi den postmoderna motreaktionen mot industrisamhällets missförhållanden samt kritiken mot existensen av den objektiva sanningen. Institutionaliseringens följder är emellertid att rörelsen slutligen upptas som en del av det sen-moderna samhällssystemet. Förändringen märks i första hand då rörelsen under 80-talet förvandlas till en ekonomiskt intresserad organisation med tjänstehierarkier och reglerat ansvar som påföljder. Den byråkratiska arbetsordningen urlakar inte bara rörelsens ideologi, utan tvingar också den nu demokratiskt tillsatte ledaren till radikala åtgärder för att återfå sin makt, något som når sin kulmen i en konflikt med ledarens sorti som yttersta konsekvens.

A Preliminary Habitat Suitability Analysis for the Restoration of South China Tigers in the Hupingshan Reserve, China

The South China tiger, Panthera tigris amoyensis, once roamed the greater part of southern China. However, expanding human populations and other anthropogenic effects have resulted in the extinction of the wild population. The Chinese government has expressed interest in a reintroduction program for this species of tigers. Recent studies suggest that the Hupingshan preserve is potentially a good candidate for a tiger reintroduction program. Hupingshan is located on the border of the Hunan and Hubei provinces in Southern China. This study was a preliminary habitat suitability analysis, for the restoration of South China tigers in the Hupingshan reserve, China. ArcGIS 9.0 was used to develop a model that combined roads, railroads, slope, land cover, park classification, and population density. The tiger habitat suitability analysis was performed by weighting and combining the various layers. Preliminary results suggest that the Hupingshan reserve is suitable habitat for the reintroduction of South China tigers.
