Avaliação de cultivares de aveia quanto à sensibilidade ao excesso de cobre no solo.

O uso intensivo de sulfato de cobre para o tratamento de míldio nas videiras tem causado acúmulos desse metal nos solos da serra gaúcha, deixando-os com altos teores de Cu.VOLMIR SCANAGATTA, CNPUV, 113912 (Colaborador)

Avaliação da capacidade de adaptação de porta-enxertos de videira às condições de excesso de umidade do solo.

A videira se adapta ao cultivo em diversos tipos de solos, mas é sensível ao alagamento, causado pelo excesso de chuvas e influenciado pela textura do solo, condição que pode afetar o desenvolvimento das raízes e favorecer a ocorrência de doenças fúngicas.Nome completo:VOLMIR SCANAGATTA, CNPUV, 113912 Colaborador

Prevalence and Severity of Asthma, Rhinitis, and Atopic Eczema in 13- to 14-Year-Old Schoolchildren from Southern Brazil

The objective of this study was to investigate the prevalence and severity of asthma, rhinitis, and atopic eczema in schoolchildren from southern Brazil. A cross-sectional study was carried out with the International Study of Asthma and Allergies in Childhood phase III written questionnaire. The questionnaire was self-applied by 2,948 randomly selected schoolchildren aged 13 to 14 years. The lifetime prevalence rates of symptoms were as follows: wheezing, 40.8%; rhinitis, 40.7%; eczema, 13.6%; self-reported asthma, 14.6%; rhinitis, 31.4%; eczema, 13.4%. Rhinitis was reported by 55% of adolescents with current asthma (60% females vs 46.9% males). Girls 13 to 14 years of age had higher prevalence rates of asthma, rhinitis, and eczema than boys had. Atopic eczema was reported by 42.7% of girls and 31.4% of boys with asthma. The prevalence rates were statistically significant for symptoms of asthma, rhinitis, and atopic eczema in females. However, there were no statistically significant differences between the sexes in regard to reported asthma and bronchospasm induced by exercise

Functional responses and scope for growth of two non-indigenous bivalve species in the Sacca di Goro (northern Adriatic Sea, Italy).

A comparative study was carried out on the functional feeding behaviour of the infaunal Manila clam, Ruditapes philippinarum, and the epifaunal Asian date mussel, Musculista senhousia, inhabiting the Sacca di Goro lagoon, in response to changing temperature and variable quantity of food. The rates of clearance (CR), ingestion (IR), absorption (AR), respiration (RR), and energy budget (scope for growth, SFG) were measured and compared. The two non-indigenous species show a similar trend for all parameters measured in the two seasons considered (late winter and summer). SFG followed a clear seasonal trend, reaching higher values in the warmer period (July) for M. senhousia and in the cooler period (March) for R. philippinarum. Probably, this seasonal divergence was a consequence of the two species’ different reproductive cycle
