Abstract Pollinators are threatened worldwide and strategies measures to support their conservation proliferating. Among them, the approach “Farming with Alternative Pollinators” (FAP) aims pollinators by seeding strips of pollinator-attracting cultivated plants surrounding crops, simultaneously providing income farmer. In this study we assessed whether supports pollinator diversity in agro-eco...
pregnancy in the rudimentary horn of uterus is rare. uterine rupture is a rare obstetrical catastrophe that occurs before 20 weeks’ gestation in 70% of unicornate uterus cases. a 24-year-old primigravida woman was referred to our hospital due to failed induction-in-17th-weeks-of-her-pregnancy. fetal-death was confirmed on abdominal ultrasound. examination under-anaesthesia revealed -pregnancy-i...
Sexual dimorphism is one of the most widespread and recognizable patterns of phenotypic variation in the biotic world. Sexual dimorphism in floral display is striking in the dioecious plant Silene latifolia, with males making many, small flowers compared to females. We investigated this dimorphism via artificial selection on two populations to determine whether genetic variation exists within p...
Flower image retrieval is a very important step for computer-aided plant species recognition. In this paper, we propose an efficient segmentation method based on color clustering and domain knowledge to extract flower regions from flower images. For flower retrieval, we use the color histogram of a flower region to characterize the color features of flower and two shape-based features sets, Cen...
The plainfin midshipman fish, Porichthys notatus, is a nocturnal marine teleost that uses social acoustic signals for communication during the breeding season. Nesting type I males produce multiharmonic advertisement calls by contracting their swim bladder sonic muscles to attract females for courtship and spawning while subsequently attracting cuckholding type II males. Here, we report intra- ...
Background: Diagnosis and management of pre-rupture stage of the pregnant horn are difficult and usually missed on a routine ultrasound scan. Furthermore, most cases are detected after rupture of pregnant horn. Case: We presented a 28-year-oldG2 L1 woman with diagnosis of RHP at 14 weeks of gestation. She was initially diagnosed with a normal intrauterine pregnancy, whereas a pregnancy in a rig...
The effect of anthropic alterations such as drain discharge on a fish community was studied in the Ribeirão Claro River, municipality of Rio Claro, State of São Paulo, southeastern Brazil. Samples were made monthly in three different points along the river (headwaters, mid course, and confluence) between December, 2003 and March, 2004, which is the reproductive period for the majority of the sp...
We introduce a Horn description logic called Horn-DL, which is strictly and essentially richer than Horn-Reg , Horn-SHIQ and Horn-SROIQ, while still has PTime data complexity. In comparison with Horn-SROIQ, Horn-DL additionally allows the universal role and assertions of the form irreflexive(s), ¬s(a, b), a 6 . = b. More importantly, in contrast to all the well-known Horn fragments EL, DL-Lite,...
Horn-to-Horn belief revision asks for the revision of a Horn knowledge base such that the revised knowledge base is also Horn. Horn knowledge bases are important whenever one is concerned with efficiency—of computing inferences, of knowledge acquisition, etc. Horn-to-Horn belief revision could be of interest, in particular, as a component of any efficient system requiring large commonsense know...
Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by...
