Ein neuer fall von veraenderungen an einer heuschrecke (Orthoptera, acrididae) durch einen parasiten.

Número abril-diciembreIm Jahr 1940 beschrieb ich einige Fälle von morphologischen Veränderungen an Orthopteren, die von parasitischen Würmern befallen waren (6.Congr. int. Ent. I, p. 341-347, t. II). Dabei kommt es zu einer Verlängerung des Abdomens und zu Abweichungen an den Elytren. Die parasitierten (männer) werden dadurch zum Teil den (frauen) ähnlich.Peer reviewe

Glass shell manufacturing in space

Residual gases always found in glass shells are CO2, O2 and N2. In those cases where high water vapor pressure is maintained in the furnace, water is also found in the shells. Other evidence for the existence of water in shells is the presence of water-induced surface weathering of the interior shell surface. Water and CO2 are the predominant volatiles generated by the pyrolysis of both inorganic and hydrolyzed metal-organic gels. The pyrolysates of unhydrolyzed metal-organic gels also contain, in addition to water and CO2, significant levels of organic volatiles, such as ethanol and some hydrocarbons; on complete oxidation, these produce CO2 and water as well. Water is most likely the initial blowing agent, it is produced copiously during the initial stages of heating. In the later stages, CO2 becomes the dominant gas as H2O is lost at increasing rates. Water in the shell arises mainly from gel dehydration, CO2 by sodium bicarbonate/carbonate decomposition and carbon oxidation, and O2 and N2 by permeation of the ambient furnace air through the molten shell wall

When The Hunt Is Over: Culture and Conservation in Kazakh Eagle Falconry

The last large scale practice of falconry that uses Golden Eagles takes place in Bayan- Ulgii, Mongolia. Recent media exposure allowed for the development of a tourism industry in the region that culminates in two annual festivals celebrating the cultural heritage. Modern eagle falconry practices have been shown to deviate from traditional hunting and training methods. While Golden Eagles are listed with a regional conservation status of Least Concern by the Mongolian Red List, these new practices place the health of Golden Eagle populations in the region at risk, especially as tourism continues to grow. Furthermore, a changing environmental climate and Mongolia’s susceptibility to climate change and desertification put not only the eagles, but also their prey base at risk. This research examined perspective of local environmental officials, tourism representatives, and local eagle hunters with respect to the status of Golden Eagles, their prey base, the health of the general ecosystem, and how tourism and modern eagle falconry practices have diverged from historical norms and the impact of such changes. Findings in literature were reviewed against the responses of Uglii officials as well as hunters from the countryside. The results show conflicting perceptions of the stability of eagle populations in the area and slight decreases in the prey base of golden eagles. In addition, data revealed that eagle hunters perceive the land of the countryside to be generally lessening in health. Falconers and officials cited growing numbers of livestock as the reason for decreasing pasturelands. Analysis of falconry methods also showed that eagle hunters are turning to trapping as the main source of attaining the raptors, and there is a growing base of people that only hold eagles for business and tourism purposes. More research should be conducted into the absolute status of the prey base to confirm local observations. The market for eagles should be examined more thoroughly, and more quantitate data should be collected in regard to land type change and other major threats to Golden Eagle populations

Teaching Tip: developing an intercollegiate Twitter forum to aid student exam study and the development of digital professionalism

#VetFinals has been developed as a novel online Twitter teaching event designed to support intercollegiate veterinary teaching using social media. Previous studies in other fields have suggested that Twitter use within universities may have benefits for undergraduate education. This “teaching tip” paper describes a project using Twitter to host online exam study sessions. The project has been a highly successful collaborative effort between the Royal Veterinary College and Nottingham Veterinary School in the UK. Over 4 years, the #VetFinals project has developed into a long-term, self-sustaining enterprise. This initiative provides a semi-structured means for student exam preparation with direct real-time input from a faculty member. It also creates a network of peers both horizontally across institutions and vertically throughout year groups. Based on similar initiatives in other disciplines, an anticipated outcome of this project was to contribute to student online professionalism. This could help address the veterinary community's recently highlighted problems with professional conduct and appropriate use of social media. Analysis of the success of this endeavor will be available in a future publication

efficiency and safety of human reproductive cell tissue vitrification

Vitrification is a cryopreservation technique increasingly applied in clinical practice for cells and tissue. This review article focuses mainly on the efficiency of vitrification of human reproductive cells and tissue, by analysing the clinical results reported in the literature. The second aspect discussed is safety of vitrification procedure. Different procedures and different types of carriers can be used, and in some cases vitrification requires a direct contact between cell/tissue/carrier and liquid nitrogen; this causes concern regarding the safety of this cryopreservation technique. Although the risk of contamination during cryopreservation remains negligible, this article explains how to overcome the hypothetical risk of contamination when using different types of vitrification carriers, in order to satisfy all existing directives
