morphological characteristics of amiata donkey reared in tuscany

In this work were studied morphological characteristics and biometric parameters of the Amiata donkey. The Amiata donkey is a local endangered breed and derives from the homonym mountain in Tuscany. This donkey, which was used, over the past, like pack animal in farms and in mines, is now involved in milk production, onotherapy and trekking. The averages and the standard deviations of the biometric parameters and the frequency of the morphological characters of foals, adult females and stallions were calculated. The measures of the adult females were estimated by ANOVA considering three different classes of age: 3-4, 5-6, over6yearsold. 3-4, 5-6, over 6 years old.. The average sizes were: height at withers of 129.8±4.7and125.8±5.6cm,thoraxcircumferenceof145.6±7.8and145.0±7.8cm, 129.8±4.7 and125.8±5.6cm,thoraxcircumferenceof145.6±7.8and145.0±7.8cm, and 125.8±5.6cm,thoraxcircumferenceof145.6±7.8and145.0±7.8cm, 125.8±5.6 cm,thoraxcircumferenceof145.6±7.8and145.0±7.8cm, , thorax circumference of 145.6±7.8and145.0±7.8cm, 145.6±7.8and145.0±7.8cm, and 145.0±7.8cm, 145.0±7.8 cm,, front shank circumference of 18.3±0.8and16.9±1.5cm,forstallionsandadultfemalesrespectively.All 18.3±0.8 and16.9±1.5cm,forstallionsandadultfemalesrespectively.All and 16.9±1.5cm,forstallionsandadultfemalesrespectively.All 16.9±1.5 cm,forstallionsandadultfemalesrespectively.All , for stallions and adult females respectively. All the observed donkeys presented dark grey coat with the shoulder stripe. The zoometric indices of the adult females did not differ between the classes and showed that the somatic adult proportions had al- ready reached in 3-4 years old donkeys. This breed showed the features of the ancestors: the shoulder stripe of the Equus asinus africanus and the legs stripes of the Equus asinus somaliensis

Effect of temperature and relative humidity on algae biofouling on different fired brick surfaces

The purpose of this study was to evaluate the effect of environmental temperature and relative humidity on algae biofouling that often occurs on porous and rough fired brick surfaces. Brick samples were chosen since their common use on building façades. Accelerated growth tests were performed under different relative humidities and different temperatures. Results showed the effects of different temperature conditions in terms of algae growth delay and reduction of the covered area. All the relative humidity conditions tested substantially showed no growth from an engineering standpoint. The modified Avrami's law succeeded in modelling the biofouling under the different environmental condition
