This article tackles some important issues relating to the analysis of a particular case of complex ancient graphic images, called “lettrines”, “drop caps” or “ornamental letters”. Our contribution focuses on proposing generic solutions for lettrine recognition and classification. Firstly, we propose a bottom-up segmentation method, based on auto-correlation features, ensuring the separation of...

Increasing environmental pollution in urban areas has been endangering the survival of carbonate stones in monuments and statuary for many decades. Numerous conservation treatments have been applied for the protection and consolidation of these works of art. Most of them, however, either release dangerous gases during curing or show very little efficacy. Bacterially induced carbonate mineraliza...

In recent years, the keeping of ornamental freshwater animals and plants in garden ponds has been growing in popularity. Water hyacinth (Eichhornia crassipes) is one of the preferred macrophytes seasonally imported mainly from South-eastern Asia throughout the world. This constitutes a secondary introduction inasmuch as the species is native to South America. Although many assemblages of aquati...

We examined the distribution of iridoviruses in 10 freshwater ornamental fish species hatched in Korea and imported from other Asian countries using both 1-step and 2-step polymerase chain reation (PCR). None of the 10 fish species analyzed were free of iridovirus as shown by 2-step PCR positive results, and 3 species yielded 1-step PCR positive results with associated mortality. Cloned PCR amp...

the periwinkle with the scientific name of catharanthus roseus is one of the most important ornamental plants of the apocynaceae family. in order to evaluate the effect of different waters on the amount of the nutrient elements in soil and aerial parts of catharanthus roseus, a factorial experiment based on completely randomized design was conducted in 3 replications. experimental treatments we...

thrips specimens were collected in the year 2014 on different ornamental plants from mahallat (markazi province), iran. in this study, 11 species in six genera and three different families of thysanoptera were collected and identified. the scientific names of thrips species are as follow: melanthrips knechteli, m. pallidior, frankliniella intonsa, f. occidentalis, microcephalothrips abdominalis...

The genus Dickeya contains bacteria causing soft rot of economically important crops and ornamental plants. Here, we report the draft genome sequences of two Dickeya sp. isolates from rotted leaves of Phalaenopsis orchids.

impatiens necrotic spot virus (insv) infects ornamental plants worldwide. it has been reported from almost every ornamental screenhouse in tehran province. insv symptoms include necrotic leaf spot, chlorosis and stunting. heavy losses have been reported from insv in plants such as zinnia elegans, ficus benjamina, viola spp., saintpaulia ioantha, althea spp., cheiranthus cheiri, pelargoniumxhort...

Bacteriophage vB_Eco_swan01 was isolated from an ornamental pool using Escherichia coli MG1655 as the host. Bacteriophage vB_Eco_swan01 has limited similarity with other known phages at the nucleotide level and likely represents a new bacteriophage species within the Tunavirinae.
