Low faunal diversity on Maltese sandy beaches : fact or artefact?
Full text linkEight sandy beaches on Malta and two on Gozo were sampled for macrofauna to test the hypothesis that Maltese beaches have
an intrinsically low diversity. Stations distributed in the supralittoral (dry zone), mediolittoral (wet zone) and upper infralittoral
(submerged zone to 1m water depth) were sampled by sieving core samples and standardised searching during daytime, and pitfall
trapping and standardised sweeping of the water column using a hand-net at night, as appropriate. Physical parameters of the
sediment were measured and human occupancy of the beaches was estimated.
From the supralittoral and mediolittoral, 39 species represented by 1584 individuals were collected by the combined techniques of
pitfall trapping, sieving and standard searching. For Ramla beach, which had the highest diversity, 267 individuals representing 25
infaunal species were collected by sieving from a combined volume of 1.175m3 of sand, and 149 individuals representing 28
epifaunal species were collected by standardised searching from a combined area of 700m2 of sand during two winter and two
summer sampling sessions between 1992 and 1993. For nine other beaches sampled during the summer of 2000, only six
macrofaunal species were collected from core samples, with overall population densities ranging from 4.13 to 45.45 individualsm 2.
Only 92 individuals belonging to 12 species were collected by hand-net from the uppermost infralittoral of five beaches sampled
using this method during the summer of 2000. Taxa of gastropods, bivalves, decapods, mysids and staphylinid beetles generally
abundant on Mediterranean sandy beaches, were entirely absent from the beaches sampled.
Few correlations that could explain the impoverishment of Maltese sandy beaches were found between physical parameters and
faunal abundances, and other factors such as inadequate sampling effort, human disturbance and marine pollution were also
excluded; however, seasonally biased sampling may partly explain the results obtained. One factor that may explain why certain
species are missing could be lack of recruitment, due to Malta’s geographical isolation from the European and African mainlands.

Non-discursive knowledge and the construction of identity. Potters, potting and performance at the bronze age tell of Százhalombatta, Hungary
Full text linkThis article explores the relationship between the making of things and the making of people at the Bronze Age tell at Százhalombatta, Hungary. Focusing on potters and potting, we explore how the performance of non-discursive knowledge was critical to the construction of social categories. Potters literally came into being as potters through repeated bodily enactment of potting skills. Potters also gained their identity in the social sphere through the connection between their potting performance and their audience. We trace degrees of skill in the ceramic record to reveal the material articulation of non-discursive knowledge and consider the ramifications of the differential acquisition of non-discursive knowledge for the expression of different kinds of potter's identities. The creation of potters as a social category was essential to the ongoing creation of specific forms of material culture. We examine the implications of altered potters' performances and the role of non-discursive knowledge in the construction of social models of the Bronze Ag
Prehabilitation. An interdisciplinary patient-centric conceptual framework
No full textObjectives: to review the recent literature around patient-centric prehabilitation in oncology patients and propose a conceptual framework to inform development of interdisciplinary prehabilitation services leading to focused, individualized prehabilitation interventions.Data sources: a review of recent peer-reviewed literature, national guidance, and government strategy on prehabilitation in oncology patients.Conclusion: patient- centric prehabilitation is key to improving patient's experiences of cancer throughout the cancer journey while improving population health and reducing financial costs. Successful personalized prehabilitation interventions are comprised of an interplay between individual interdisciplinary roles, as illustrated in the conceptual framework. The role of the nurse underpins this whole process in patient screening, assessment, implementation of the intervention, and patient reassessment, ensuring care is dynamic and tailored to patient need.Implications for nursing practice: the review has discussed the key role that nurses play in the process but warrants more research in the area. The conceptual framework provides a basis to develop interdisciplinary prehabilitation services underpinned by the nurse's role. The review advocates the use of educational interventions to equip all health professionals with prehabilitation knowledge to enable interdisciplinary prehabilitation services to be developed.</p

A Sailor's Farewell
A sweet young maid was strolling on the sandy shore one day,
She was freaming of a sailor boy in blue,
The message that he gave to her before he sailed away,
Come take these words, sweetheart, I love but you.
This letter will explian to you a thing I dare not tell,
He murmured e'er he joined his gallant crew,
And if it finds an answer in your heart, dear little Nell,
Just wait for me beside the ocean blue.
Refrain:
When the sun slowly sinks to its rest,
Then her gaze wanders off to the west,
For she's dreaming each day, of a lad far away,
Whose love she ne'er forgets,
And she sighs as she waits patiently,
For she wonders where he can be,
There's a sob and a tear for each long weary year,
As she waits by the deep blue sea.Funding for digitization provided by the Arkansas Humanities Council and the Happy Hollow Foundation
Measurement and Computation of Movement of Bromide Ions and Carbofuran in Ridged HUmic-Sandy Soil
No full textWater flow and pesticide transport in the soil of fields with ridges and furrows may be more complex than in the soil of more level fields. Prior to crop emergence, the tracer bromide ion and the insecticide carbofuran were sprayed on the humic-sandy soil of a potato field with ridges and furrows. Rainfall was supplemented by sprinkler irrigation. The distribution of the substances in the soil profile of the ridges and furrows was measured on three dates in the potato growing season. Separate ridge and furrow systems were simulated by using the pesticide emission assessment at regional and local scales (PEARL) model for pesticide behavior in soil–plant systems. The substances travelled deeper in the furrow soil than in the ridge soil, because of runoff from the ridges to the furrows. At 19 days after application, the peak of the bromide distribution was measured to be in the 0.1–0.2 m layer of the ridges, while it was in the 0.3–0.5 m layer of the furrows. After 65 days, the peak of the carbofuran distribution in the ridge soil was still in the 0.1 m top layer, while the pesticide was rather evenly distributed in the top 0.6 m of the furrow soil. The wide ranges in concentration measured with depth showed that preferential water flow and substance transport occurred in the sandy soil. Part of the bromide ion distribution was measured to move faster in soil than the computed wave. The runoff of water and pesticide from the ridges to the furrows, and the thinner root zone in the furrows, are expected to increase the risk of leaching to groundwater in ridged fields, in comparison with more level fields
Structural analysis and parametric study ballasted track in sandy regions
No full textThe sand intrusion in railway tracks in sandy regions can significantly change the mechanical behaviour of tracks and thus threaten the safety of train operation. This paper presents substantial field tests on both sandy and clean railway tracks to study the effect of sand intrusion on the longitudinal resistance of ballast bed and the vibration behaviour of track structures. After that, a 3D multi-scale the discrete element model is developed to study the micro-contact between ballast particles and the vibration behaviour of sandy tracks during train passing in detail. Also, the effect of train speeds and axle loads on the mechanical behaviour of sandy tracks is discussed. The results show that the sand intrusion increases the vibration acceleration amplitude of rail and sleeper by 11.3% and 50.3%, while ballast bed decreases by 44.9%. Besides, the sand intrusion significantly changes the energy distribution in the track, wherein the frequencies of the highest energy of rail and sleeper are increased while that of the ballast bed is decreased. The parametric study shows the high train speed can cause the increase in overall acceleration of the ballast bed and high axle load can cause an increase in the micro-contact forces between ballast particles, diffusion angle of the contact force chain, displacements of ballast particles, acceleration of ballast particles, and sleeper displacements.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Mechanics and Physics of Structure
Crushed rock and clay amelioration of a nutrient decifient, sandy soil of Maputaland
No full textBibliography: leaves 57-62.Various studies have suggested the possibility that food derived through subsistence agriculture in the Mseleni region of Maputaland contributes to malnutrition within the local community, particularfy within the high proportion of the population which suffers from a severe, disabling form of osteoarthritis. This study was conducted to determine if the application of local crushed rock or black clay to these nutrient deficient, sandy soils would increase available nutrient concentrations and improve the growth of plants in the ameliorated soil
