The present study aimed to determine the effects of lucantin red and yellow and also astaxanthin on the growth, hematological and immunological parameters, and coloration of the tiger oscar (Astronotus ocellatus). To this end, 120 fingerlings of tiger oscar were equally and randomly divided into 12 aquariums. The fish were fed with experimental diets for 8 weeks. Treatments included diets conta...

BACKGROUND Cyperus esculentus tubers (tiger nut) are one of the ancient food sources known to humanity. It is traditionally used in the Middle East to stimulate sexual arousal in men. However, there has been no scientific evidence about its assumed aphrodisiac properties. This study aimed to investigate the influence of tiger nut on the copulatory behavior of sexually active male rats. METHOD...

This paper is a contribution to the ongoing discussion on treebank annotation schemes and their impact on PCFG parsing results. We provide a thorough comparison of two German treebanks: the TIGER treebank and the TüBa-D/Z. We use simple statistics on sentence length and vocabulary size, and more refined methods such as perplexity and its correlation with PCFG parsing results, as well as a Princ...

A 14-year-old male Siberian tiger (Panthera tigris altaica) was admitted with an ulcerating mass on the right thoracic wall. Radiographic and computed tomographic evaluation indicated 2 isolated cutaneous masses without any signs of metastasis. Histology of a Tru-Cut biopsy revealed an anaplastic sarcoma with giant cells. Both tumors were resected with appropriate normal tissue margins. The siz...

Despite being targeted as a conservation flagship species for several decades, the tiger (Panthera tigris) grows ever more imperiled. Debate exists as to where tiger conservation should focus: on protected nature reserves or larger landscapes. We developed a landscape scale, density-based model to assess whether reasonably effective management of current reserves is adequate to ensure the survi...

A thin unhealthy Burmese boy named Moung Tsan, aged 15 years, was attacked by a tiger in the jungle, when returning from an adjacent hill accompanied by his father, oil the evening of the'Jth July 1881. The tiger caught him on the face and dragged him several yards, when his father, who had a dah in his hand, struck the animal on the head, on which the tiger left his prey and jumped on the fath...

Naïve red (Lasiurus borealis Müller) and big brown (Eptesicus fuscus Beauvois) bats quickly learn to avoid noxious sound-producing tiger moths. After this experience with a model tiger moth, bats generalize the meaning of these prey-generated sounds to a second tiger moth species producing a different call. Here we describe the three-dimensional kinematic and bioacoustic details of this behavio...

This paper presents the annotation of the German TIGER Treebank. First, issues concerning the annotation, representation as well as querying of the treebank are discussed. Within this context, the annotation tool ANNOTATE, the export and XML formats of the TIGER Treebank and the TIGER search tool are briefly introduced. Secondly, the developments of the TIGER annotation scheme and their realiza...

New cross-country evidence for 1965 to 1995 is presented on the link that runs from population change to economic growth. The estimates indicate that demographic change is a powerful determinant of income growth, operating mainly via the effect of changes in age structure. The estimates also indicate that the benefits of demographic change can be greatly magnified by a favourable policy environ...
