Vertebral pain in helicopter pilots

Pathological forms of spinal pain engendered by piloting helicopters were clinically studied. Lumbalgia and pathology of the dorsal and cervical spine are discussed along with their clinical and radiological signs and origins

Síndrome uña-rótula

Presentamos el estudio de 3 casos afectos de un síndrome "uña-rótula", con historia familiar positiva en uno de ellos. Este síndrome es un transtorno hereditario de transmisión autosómica dominante, caracterizado por displasia ungueal y de articulacione s y formación de una s excrecencia s óseas características a nive l del ilíaco (cuernos ilíacos). El síndrome completo se define por los cambios esqueléticos asociados a una nefropatía. Describimos las anomalías clínico-radiográficas de tres paciente s y realizamos una revisión de la literatura sobre esta displasia poco frecuente.The author s showed thre e patients affected by "nail patella" syndrome with positive familiar history in one case. The "nail patella" syndrome is an autosomal dominant condition, characterized by nail and joint dysplasia and extra bone formation at the os ilium. The complet e syndrome is characterized by a serie s of skeletal disorders and specific nephropathy. This article reports the clinical and roentgenographi c findings of three patients and the results of the study of their families. A review of the literature is done

Use of a managed solitary bee to pollinate almonds: Population sustainability and increased fruit set

Osmia spp. are excellent orchard pollinators but evidence that their populations can be sustained in orchard environments and their use results in increased fruit production is scarce. We released an Osmia cornuta population in an almond orchard and measured its population dynamics, as well as visitation rates and fruit set at increasing distances from the nesting stations. Honeybees were 10 times more abundant than O. cornuta. However, the best models relating fruit set and bee visitation included only O. cornuta visitation, which explained 41% and 40% of the initial and final fruit set. Distance from the nesting stations explained 27.7% and 22.1% of the variability in initial and final fruit set. Of the 198 females released, 99 (54.4%) established and produced an average of 9.15 cells. Female population growth was 1.28. By comparing our results with those of previous O. cornuta studies we identify two important populational bottlenecks (female establishment and male-biased progeny sex ratios). Our study demonstrates that even a small population of a highly effective pollinator may have a significant impact on fruit set. Our results are encouraging for the use of Osmia managed populations and for the implementation of measures to promote wild pollinators in agricultural environments

Seasonal variation of inter-limb jumping asymmetries in youth team-sport athletes

The main objective of the present study was to provide seasonal variation data for inter-limb asymmetry in youth elite team-sport athletes. Fifty-nine players performed the single leg countermovement jump (SLCMJ) and the one leg hop for distance (OLHT) tests during pre-season, mid-season and end-season. A repeated-measures analysis of variance was conducted to determine magnitude differences in asymmetry scores between time points. Kappa coefficients (κ) were calculated to determine the levels of agreement for the direction of asymmetry. When comparing inter-limb asymmetry magnitudes across the season, the SLCMJ test showed significantly higher asymmetries at mid-season in comparison with pre-season and end-season (p<0.01, d=-1.03 for pre to mid; p<0.01, d=1.12 for pre to end). However, OLHT inter-limb asymmetry magnitude remained consistent throughout the season (ES range=-0.02 to -0.06). For the direction of asymmetry, levels of agreement ranged from poor to slight in the SLCMJ (k-0.10 to 0.18) and in the OLHT (k-0.21 to 0.18). No significant differences were found between mean asymmetry values at any time point or for either test when comparing males and females. In conclusion, jump height asymmetry during the SLCMJ was the only metric to show significant magnitude changes across the season

Estratigrafia d’es Dolç (Colònia de Sant Jordi, Mallorca)

Les tasques de recerca espeleològica mitjançant tècniques d’espeleobusseig a la cova des Dolç (Colònia de Sant Jordi, Mallorca) han permès observar la seqüència estratigràfica de transició Plio-quaternària en el sector sud-oriental de la conca de Campos. Es tracta d’una seqüència regressiva que evoluciona des de fàcies bioturbades de plataforma soma, a fàcies d’aigües salobroses i finalment de deposició eòlica que constitueix la major part de la sèrie. La composició calcarenítica majoritàriament d’origen eòlic en la qual es desenvolupa la cova li dóna un tret diferencial genètic respecte de la major part de cavitats litorals del migjorn i llevant de Mallorca desenvolupades sobre els materials calcaris escullosos del Miocè superior

Luis Mariano Vidal (1842-1922) rudist taxa revisited

The revision of the 323 register numbers of rudist bivalves in the Vidal Collection, kept at the Museu de Geologia de Barcelona (MCNB), allowed the identification and re-figuration of thirty-three holotype or syntype specimens corresponding to twenty species established by Vidal. Among them, thirteen are considered as valid species, four resulted to be synonymous with other senior species, and three (one not figured) do not display enough characters to be properly identified. The four syntypes of Hippurites castroi, currently attributed to genus Hippuritella, have not been localised, nor the other two specimens subsequently figured by the author. Similarly, three of the four syntypes of Hippurites maestrei, type species of Hippuritella, have not been localised. Contrarily, the specimens described as Sphaerulites posae but not figured, were localised. On the other hand, twelve specimens, syntypes or figured as new species by other authors (Matheron and Douvillé), have also been identified and are re-figured; most of them are part of the specimens that were sectioned for study and then returned to Vidal. In addition, other seventeen specimens figured by Douvillé have been identified and are documented; most of them also being part of a sectioned specimen
