On the ability of statistical wind-wave models to capture the variability and long-term trends of the North Atlantic winter wave climate

A dynamical wind-wave climate simulation covering the North Atlantic Ocean and spanning the whole 21st century under the A1B scenario has been compared with a set of statistical projections using atmospheric variables or large scale climate indices as predictors. As a first step, the performance of all statistical models has been evaluated for the present-day climate; namely they have been compared with a dynamical wind-wave hindcast in terms of winter Significant Wave Height (SWH) trends and variance as well as with altimetry data. For the projections, it has been found that statistical models that use wind speed as independent variable predictor are able to capture a larger fraction of the winter SWH inter-annual variability (68% on average) and of the long term changes projected by the dynamical simulation. Conversely, regression models using climate indices, sea level pressure and/or pressure gradient as predictors, account for a smaller SWH variance (from 2.8% to 33%) and do not reproduce the dynamically projected long term trends over the North Atlantic. Investigating the wind-sea and swell components separately, we have found that the combination of two regression models, one for wind-sea waves and another one for the swell component, can improve significantly the wave field projections obtained from single regression models over the North Atlantic.

Transcriptome and gene expression profile of ovarian follicle tissue of the triatomine bug Rhodnius prolixus

Insect oocytes grow in close association with the ovarian follicular epithelium (OFE), which escorts the oocyte during oogenesis and is responsible for synthesis and secretion of the eggshell. We describe a transcriptome of OFE of the triatomine bug Rhodnius prolixus, a vector of Chagas disease, to increase our knowledge of the role of FE in egg development. Random clones were sequenced from a cDNA library of different stages of follicle development. The transcriptome showed high commitment to transcription, protein synthesis, and secretion. The most abundant cDNA was a secreted (S) small, proline-rich protein with maximal expression in the vitellogenic follicle, suggesting a role in oocyte maturation. We also found Rp45, a chorion protein already described, and a putative chitin-associated cuticle protein that was an eggshell component candidate. Six transcripts coding for proteins related to the unfolded-protein response (UPR) by were chosen and their expression analyzed. Surprisingly, transcripts related to UPR showed higher expression during early stages of development and downregulation during late stages, when transcripts coding for S proteins participating in chorion formation were highly expressed. Several transcripts with potential roles in oogenesis and embryo development are also discussed. We propose that intense protein synthesis at the FE results in reticulum stress (RS) and that lowering expression of a set of genes related to cell survival should lead to degeneration of follicular cells at oocyte maturation. This paradoxical suppression of UPR suggests that ovarian follicles may represent an interesting model for studying control of RS and cell survival in professional S cell types.

Problematiska ljudkvalitetsskillnader vid liveproduktioner i samma lokal : En studie av upplevd ljudkvalitet vid två DJ-akters framträdanden under Dreamhack Winter 2014

Syftet med denna undersökning är bidra med förklaringar till varför upplevda ljudkvalitetsskillnader kan uppstå mellan olika akters framträdanden vid event och festivaler trots att de använder samma utrustning och är i samma lokal och att förklaringarna ska utgöra en kunskapskälla för dem som eftersträvar en god ljudkvalité vid liveframträdanden. De metoder som har används är fallstudie, webbenkät, intervjuer och egen observation. Webbenkäten användes på Dreamhack Winter 2014 där en grupp undersökningsdeltagare svarade på frågor om två olika DJ-akter på scenen i D-hallen, Elmia. Fem personer deltog som intervjupersoner: scenansvarig från Dreamhack, tre ljudtekniker ifrån olika ställen i Sverige och en person som jobbar med ljudteknisk konsultation och ljudmätning. Samtliga intervjuer genomfördes via mail. Intervjuerna eftersträvade att ge kunskap om dessa personers funderingar kring ljudkvalitetsproblemet och scenansvarig svarade på frågor om scenen på Dreamhack. En observation av upplevd ljudkvalitet och ljudteknikernas arbetssätt genomfördes av mig själv på Dreamhack Winter 2014. Resultatet från såväl enkätundersökningen som den egna observationen visar att inga stora upplevda skillnader fanns mellan de två akterna på Dreamhack Winter 2014. De upplevda skillnader som observerades var negativa anmärkningar, så som mängden bas och ljudstyrka. Intervjuerna visade på flera gemensamma åsikter bland ljudteknikerna angående förklaringar till ljudkvalitetsskillnader vid event som Dreamhack Winter 2014 där de ansåg att en kunnig och erfaren ljudtekniker, duktiga musiker, väl genomförd soundcheck och bra och rätt användande av utrustningen på scen krävs för att uppnå en upplevd god ljudkvalitet live. De förklaringar som finns enligt mina analyser och bland ljudteknikerna till negativa ljudkvalitetsskillnader inom liveljud i samma lokal är att ljudteknikern och musikerna är olika duktiga. Utrustning, soundcheck och akustik påverkar också kvalitén. Undersökningens sammantagna resultat tyder på att de upplevda ljudkvalitetetsskillnader som fanns på Dreamhack Winter 2014 berodde på bristande kompetens och engagemang hos tjänstgörande ljudtekniker och upplevda skillnader i bas- ljudnivå i de två DJ-akternas mixar.

The Movement of the Gastrop Littorina Littorea in the Intertidal Zone during the Onset of Winter

The movement of the snail Littorina littoreaon the North Atlantic coast is poorly understood. Most research has concentrated on the vertical distribution of the snail, and suggests that it prefers the low intertidal zone where its food source is most plentiful. In the winter, this distribution is reinforced by a documented seaward migration of snails from the high intertidal zone in response to falling temperatures. From October 14, 2006 to January 22, 2007, I examined the individual movements and recovery of snails in response to the onset of winter. I proposed that falling water and air temperatures drive the majority of snail movement within the intertidal zone, and that water temperature had the greater effect. I also examined the possibility that, in addition to a seaward migration, winter weather patterns in the Gulf of Maine and their effect on the ocean may encourage the wintertime vertical distribution of snails. Finally, I examined the possibility that populations of snails in the comparatively inhospitable high intertidal zone may endure the winter if given access to proper resources.

Effect of dietary energy and stocking density on the performance and sensible heat loss of broilers reared under tropical winter conditions

The objective of the present study was to evaluate the effects of different dietary energy levels and stocking densities on the thermoregulating parameters, live performance, and carcass traits of broilers reared under tropical winter conditions at different times of the day. In total, 1,312 one-d-old male broilers were used. Birds were allotted to three different stocking densities (10, 14 or 18 birds/m²) and two dietary energy levels (2900 or 3200 kcal ME/kg). The following parameters were evaluated:radiant heat load (RHL), rectal temperature (RT), feed intake (FI), weight gain (WG), feed conversion ratio (FCR), livability (L), production of live weight per area (WA), and carcass yield. Stocking density did not affect sensible heat loss (SRL) or rectal temperature (RT); however, as expected, sensible heat loss (SRL) and RT were influenced by time of the day, with higher values in the morning and in the afternoon, respectively. There was no effect of treatment (p>0.05) on carcass or parts yield. Feed intake was reduced in 3%, whereas weight gain and feed conversion ratio improved in 8 and 10%, respectively, as dietary energy level increased. on the other hand, stocking density did not influence live performance or carcass traits. Based on the present results, it is concluded that sensible heat loss depends on dietary energy levels and particularly on time of the day. Therefore, environmental house management is suggested during tropical winters in order to reduce differences between broiler skin and environmental temperatures in the morning and in the afternoon.

Economic analysis of cucumber and lettuce intercropping under greenhouse in the winter-spring

A análise econômica complementa a avaliação da eficiência dos cultivos consorciados, considerando além da produção física das culturas, o preço dos produtos segundo sua classificação qualitativa e época do ano. Avaliou-se economicamente consórcios de alface crespa e pepino, em duas populações de plantas, no inverno-primavera, em casa de vegetação, em Jaboticabal, SP, Brasil. Foram calculados o custo operacional total (COT), a receita bruta (RB) e o lucro operacional (LO) das culturas do pepino e alface em monocultura e em consórcio. A mão-de-obra foi a componente com maior participação no COT das culturas em consórcio e monocultura. Maiores RB e LO foram observadas nos cultivos consorciados estabelecidos com o transplante da alface e do pepino no mesmo dia, independente da densidade populacional. Considerando-se o lucro operacional e o índice de uso eficiente da área, recomenda-se o cultivo consorciado com transplante da alface até 10 dias após o transplante (DAT) do pepino, com duas linhas, e ao 0 DAT do pepino cultivado com uma linha no canteiro
