The Rose-ringed Parakeet Psittacula krameri (Scopoli, 1769) has become invasive in several countries, including South Africa, mainly through the pet trade releases and escapees. We conducted an online questionnaire survey targeting residents Durban, eThekwini Municipality, KwaZulu-Natal, Africa. aimed to determine distribution, habitat diet of Parakeet. also determined if public perceived parak...

This paper describes an exemplar-based model of people’s classification and typicality judgements in both single and combined categories. This model, called the diagnostic evidence model, explains the observed family resemblance structure of single categories; the productive nature of category combination; the observed overextension of typicality judgments in some combined categories; and the s...

A Source of Variation in Avian Growth Studies: undigested food.--In studies of avian biology, standardized growth curves are often obtained by weighing young at regular intervals. What is measured, in fact, is the bird plus the unassimilated food in the gut, some of which will be eventually assimilated but some of which will be excreted. Food in the gut is a source of variation in weight studie...

Objective(s): To investigate the diagnostic accuracy of positron emission mammography (PEM) and positron emission tomography/computed tomography (PET/CT) for small breast tumors of less than 20 mm in size.Methods: The study was conducted on a total of 100 subjects (i.e., 50 patients with pathologically proven breast cancer and 50 normal cases of medical screening). The total number of tumors wa...

Insectivorous birds are particularly vulnerable to nematodes with heteroxenous life cycles. Although there many studies on bird filarioids, they mainly focus economically important or pet species, and as a result, the species diversity of these parasites is insufficiently studied. Research genus Diplotriaena their hosts neglected, although globally occurring dangerous low specificity final host...

Until recently PET scanning has been available only at major universities or teaching hospitals possessing the necessary resources and expertise to operate a research PET facility. Most dedicated PET centers cost several millions of dollars, and include a cyclotron, a radiochemistry laboratory to synthesize PET radiopharmaceuticals, a multicrystal dedicated PET camera, advanced computer f...

Background: To retrospectively describe imaging characteristics of liver metastases on fused FDG-PET/ MRI data sets and to compare the diagnostic accuracy of MRI and fused FDG-PET/MRI data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. Materials and Methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by FDG-PET...

Fruit loss to birds is a long-standing and costly problem for many producers. We conducted a survey of Honeycrisp apple, blueberry, cherry, and wine grape growers in California, Michigan, New York, Oregon, and Washington to estimate costs of bird damage and benefits of bird damage management. We also assessed grower perceptions of impacts on profits and effectiveness of bird management techniqu...
