BACKGROUND: The aim of this study was to characterise the mycoflora and the presence of fumonisin in sorghum grains, correlating the results with the environment and abiotic factors. RESULTS: Fifty samples (five collections of ten samples each) of sorghum were analysed. All samples were found to be contaminated with fungi, with higher frequencies of Cladosporium spp. (61.8%) and Helminthosporium spp. (33.4%). Fusarium verticillioides was isolated from 15.1% of the samples, with 38% of them being contaminated with fumonisin B(1) (FB(1)) at levels ranging from 50 to 368.78 ng g(-1). Regarding abiotic factors, temperature, water activity and rainfall showed a positive correlation with the frequency of F. verticillioides and FB(1) production. There was a significant positive correlation between relative air humidity and FB(1) production. The results obtained from sexual crosses between standard F mating tester strains and the isolated strains confirmed that the strains isolated were F. verticillioides. CONCLUSION: It can be concluded that the decrease in F. verticillioides and fumonisin contamination occurred owing to atypical climatic factors during the period of sorghum cultivation, when there was any occurrence of rain and the level of water activity of grains did not reach 0.58.

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 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.

The objective of this research was to determine the effect of two sowing times on phytomass production of two varieties of Slylosanthes guianensis (var. pauciflora and var. vulgaris). Two experimental periods were studied (1: January - May/1998 and 2: November/1998 - March/1999) using a completely randomized factorial design 2 x 2 x 14 (two periods, two varieties and fourteen ages of evaluation), with four replications. The results showed a difference between the periods concerning the growth and development of Stylosanthes, and that period 2 was the most favourable to this forage plant. There was, also, different adaptability between the two varieties concerning the sowing times. The var. pauciflora was more adapted in period 1, and the var. vulgaris, in period 2. The data showed the possibility of selecting Stylosanthes cultivars adapted to different seasonal conditions.

Avaliou-se a produtividade de grupos de alface e da rúcula, em consórcio, em relação aos seus cultivos solteiros, na UNESP Jaboticabal, em condições de campo, em duas épocas de cultivo, maio a agosto e setembro a novembro de 2001, sob delineamento de blocos casualizados, com quatro repetições. Os tratamentos constaram de combinações dos fatores grupos de alface (crespa, cv. Vera; lisa, cv. Elisa e americana, cv. Tainá), sistemas de cultivo (consórcio e cultivo solteiro) e épocas de semeadura da rúcula para o estabelecimento do consórcio [0; 7 e 14 dias após o transplante (DAT) da alface]. As maiores matérias fresca e seca de alface foram obtidas na primavera, com destaque para a alface americana. As alfaces não foram afetadas pelo sistema de cultivo. A maior matéria fresca de rúcula, no outono-inverno, foi obtida em consórcio, a 0 DAT, com as alfaces crespa e lisa e, aos 7 DAT com americana, enquanto na primavera, quando foi consorciada aos 7 DAT com alface crespa e a 0 DAT com alfaces do grupo lisa e americana. A rúcula teve sua matéria seca reduzida nos consórcios estabelecidos tardiamente, aos 14 DAT. Os cultivos consorciados apresentaram-se superiores aos cultivos solteiros entre 5 e 93%, segundo o índice de uso eficiente da terra. Os maiores índices de uso eficiente da terra foram obtidos com os consórcios de rúcula e alface crespa a 0 DAT (1,93), no outono-inverno e pelas mesmas hortaliças aos 7 DAT (1,84), na primavera.

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.
