A new formula with reduced ethanol content (55%) in combination with 10% propan-1-ol, 5.9% propan-1.2-diol, 5.7% butan-1.3-diol and 0.7% phosphoric acid exhibited a broad spectrum of virucidal activity. In quantitative suspension tests, with and without protein load, this formulation reduced the infectivity titre of seven enveloped (influenza A and B, herpes simplex 1 and 2, bovine corona, respiratory syncytial, vaccinia, hepatitis B, bovine viral diarrhoea) and four non-enveloped (hepatitis A, polio, rota, feline calici) viruses >10(3)-fold within 30s. In comparative testing, only 95% ethanol showed similar levels of activity. In fingerpad tests, the formulation produced a log10 reduction factor of the titre of poliovirus type 1 (Sabin) of 3.04 in 30s compared with 1.32 by 60% propan-2-ol. Testing against feline calicivirus produced a log10 reduction factor of 2.38 by the test formulation; in contrast, the log10 reduction factors with 70% ethanol and 70% propan-1-ol were 0.68 and 0.70, respectively.

This study investigated elementary school students' environmental knowledge and attitudes, the effects of sociodemographic variables on environmental knowledge and attitudes, and how self-reported environmentally friendly behaviour is related to environmental knowledge, behavioural intentions, environmental affects, and the students' locus of control. Data were gathered by administration of the Children's Environmental Attitudes and Knowledge Scale and Locus of Control scale to 1140 students from 18 randomly selected elementary schools located in urban areas of Ankara, the capital of Turkey. Descriptive results indicated low levels of knowledge, but favourable attitudes toward the environment. The three-way ANOVA provided a significant main effect on students' environmental knowledge of education level of fathers. The sex difference regarding students' attitudes toward the environment was statistically significant in favour of girls. In addition, multiple regression analysis results showed that behavioural intentions, environmental affects, and locus of control, could be accounted as significant predictors of self-reported environmentally friendly behaviour. On the other hand, the present study showed that elementary school students' behaviours toward the environment were independent from their knowledge of environmental issues.

Abstract. In this study, we aimed to determine the slaughter-carcass characteristics, meat quality, and fatty acid composition in lambs raised under intensive and extensive conditions. The animal material consisted of 30 Norduz male lambs, with an average age of 171 days. The lambs were divided into two groups: concentrate-fed lambs (CO) and pasture-fed lambs (PS). The results showed that the CO lambs had heavier carcasses (p< 0.001), a higher dressing percentage (p< 0.001), and higher intramuscular fat (p< 0.01) than the PS lambs. It was determined that the longissimus thoracis muscle of the CO lambs had a lower ultimate pH and higher L * and water-holding capacity than the PS lambs. In this study, intramuscular fat (longissimus thoracis, semimembranosus, triceps brachii), subcutaneous and tail fat samples were used to evaluate the effect of feeding system on fatty acid composition. The polyunsaturated fatty acid to saturated fatty acid ratio (PUFA / SFA) of intramuscular fat was found to be significantly higher in the CO group than in the PS lambs, while similar subcutaneous and tail fat results were found in both groups. Moreover, the PS lambs had a lower n6 / n3 ratio and higher percentage of omega-3 than the CO lambs in all tissues studied (p< 0.05). Overall, the CO lambs have heavier and fattier carcasses with better meat quality traits than the PS lambs. However, the effects of feeding system have varying results based on the fatty acid composition of different types of fat deposits.

The bovine enterovirus type 1 (BEV-1) infection has a wide range of host spectrum including humans. In this study, seroprevalence of BEV-1 was investigated in eight mammalian species. Blood serum samples were collected from 244 humans, 1520 cattle, 272 horse, 126 dog, 281 sheep, 477 goat, 18 camel (Camelus dromedarius) and 82 gazelle (Gazella subgutturosa subgutturosa) in different regions of Turkey. Microneutralization tests showed that gazelle and camel did not have any seropositivities, but seropositivities were detected in humans (30.3%), cattle (64.8%), horse (12.8%), dog (3.2%), sheep (32.8%) and goat (27.6%).
