Following the discovery of hypersensitivity pneumonitis caused by the inhalation of mollusc shell dust in two workers from a nacre-button factory, the health status of 26 workers employed in sawing mollusc shells was investigated. The evaluation included the administration of two questionnaires and radiological, functional and immunological assessments of all workers at the outset and 1 year la...

second line replace ‘2,000 mollusc species’ with ‘4,500 mollusc species’. Identifying important sites for conservation of freshwater biodiversity: extending the species-based approach

This article describes an interactive proof development shell, Mollusc Richards 93], which can be used to construct and edit proofs in sequent-based logics. Conceptually, Mollusc may be thought of as a logic-independent successor to Oyster Bundy et al 90]. However, where Oyster was tied to a variant of Martin-LL of type theory, Mollusc can be used with any sequent-based logic for which a suitab...

C ages were measured on replicate samples of burnt grain and five mollusc species collected from a single, sealed layer at an archaeological site (Hornish Point) on the west coast of South Uist, Scotland. The aim was to examine the impact of using different mollusc species on ΔR determinations that are calculated using the paired terrestrial/marine sample approach. The mollusc species examined ...

this study assesses the effect of major trace metals levels in wastewater discharges and sedimentfrom twenty four permanent and five semi-permanent wastewater drain outlets into the kuwait coast. theeffect of trace metals levels released from untreated wastewater discharges to euchelus asper, gastropod was also determined. results showed high trace metal levels in e. asper tissues, followed by ...

The objectives of the survey were to analyse the structure of the mollusc communities in the mining subsidence reservoirs that were created as a result of land subsidence over exploited hard coal seams and to determine the most predictive environmental factors that influence the distribution of mollusc species. The reservoirs are located in urbanised and industrialised areas along the Trans-Reg...

We demonstrate that nature has produced a close-packed helical twisted filamentous material in the biomineralization of mollusc. In liquid crystals, twist-bend nematics have been predicted and observed. present analyse evidence biomineral microstructure mollusc shells may be formed from such liquid-crystal precursor.

The roles of terrestrial molluscs in many important ecosystem processes are largely unknown, particularly in tropical forests. It has been suggested from studies in temperate forests that snails/slugs contribute to litter decomposition directly (by their own metabolism) and/ or indirectly (by habitat modification enhancing micro-arthropod or microbial activity). Forty-two mesocosms were establi...
