during spring and summer of 2010 and 2012, several surveys were conducted in different vineyards in kohgiluyeh & boyer-ahmad (southwestern iran) and kerman (southeastern iran) provinces, with the aim of isolating and identifying fungi associated with grapevine decline diseases. the samples collected comprised diseased grapevines showing yellowing, defoliation, reduced growth, wilting, intervein...

In any country, identifying high-intensity accident hotspots is essential in establishing effective techniques to minimize sites. Because of Jordan's continual population growth recent years, vehicle ownership has grown, leading an increase rates. According many researches, Jordan suffers from damages caused by traffic accidents. As a result, the current study focuses on finding black spots sel...

During year 2008–11, some infected leaves of eucalypt trees (Eucalyptus camaldulensis Dehnh.) having blight and spot symptoms were collected in Golestan province (N Iran). The necrotic spots were appeared on both surfaces of the leaves and were circular to irregular, single to confluent, medium brown to light brown with red brown margin (Fig. 1A & B). In some cases, young leaves have been sever...

Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...

In Flanders, approximately 1014 accident locations are currently considered as ‘dangerous’. These ‘dangerous’ accident sites or ‘black spots’ are selected by means of their historic accident data for the period 1997-1999. More specifically; a combination of weighting values, respectively 1 for each light injury, 3 for each serious injury and 5 for each deadly injury (1_3_5), is used to rank and...

this paper deals with the study of a leaf spot disease observed on aloe vera leaves in various nurseries and botanical gardens during the routine surveys of two consecutive years of 2010 and 2011. the symptoms appeared in the form of circular to oval, brown to black, sunken spots on abaxial surface of leaves. the disease was observed only in january to february during the survey. colonieson pda...

Because the magnitude of selection can vary between sexes and in space and time, sexually antagonistic selection is difficult to demonstrate. In a Swiss population of barn owls (Tyto alba), a heritable eumelanic colour trait (size of black spots on ventral feathers) was positively selected with respect to yearling survival only in females. It remains unclear whether the absence of negative sele...

This thesis is a contribution to the fields of distributed artificial intelligence, parallel logical programming and parallel processing of neuronal networks on a cluster of workstations. A logical application language is described which was designed specifically for quality assurance for agricultural products. The application language supports access to databases. The logical application langu...

Four parents (Mash 1, Mash 3, MM 33-40, and 45726) were used to study inheritance of four qualitative characters, i.e., pubescence, seed coat colour, presence of spots on the seed coat and pod colour. All the four traits revealed monogenic nature of inheritance segregating in Mandelian ratio (3:1). The hairiness pattern was observed dominant over non-hairiness; brown seed coat colour dominant o...
