Polyphenol oxidase (PPO) activity varied in differentiation from hyphae to rhizomorph and croute in A. mellea. In undifferentiated hyphae there was not any PPO activity, while croute showed the highest activity. Electrophoresis in the presence of SDS allows the detection of intensive enzyme forms of PPO, and can also convert slower migrating enzyme forms to faster ones. Some fluorescent co...

In complex distributed environments, it is important to achieve high degree of machine-to-machine interaction, not only on a functional, but on a semantic level. Therefore, we propose the NOMADS (Networks of Mobile Adaptive Dependable Systems) Republic, a vision of the future community open to all interested hardware and software entities, and based on adaptive and, if necessary, composable ser...

BACKGROUND Pastoral social-ecological systems (SESs) are adaptive and complex systems rooted in the extensive exploitation of forage plants for livestock-based livelihoods and culture. There are species and relations that are foundational to the existence of these SESs. Nucularia perrinii Batt. (Chenopodiaceae) is an endemic halophyte plant of central and western Sahara seldom cited in the scie...

Sudan has high maternal mortality. The rate among nomads groups of people who move from place to place as a way of obtaining food, finding pasture or make a living is very high and varies between different regions of the country. The objective of the study is to identify the factors affecting the utilization of maternal health care services by nomadic communities in Sudan, to make recommendatio...

The paper describes the goal and practice of the nomadic exhibition guide Hippie. Hippie takes into account the context of use of the nomadic system. An information system is said to be nomadic when the user has access to both his or her personal information space and to the public information space from all places independent from specific devices—for nomadic systems see (Kleinrock 1997). For ...

This volume evolved from a 1997 symposium held at the American Asso­ ciation for the Advancement of Science (AAAS) Meetings in Seattle, Washington. This symposium drew together the leading scholars of nomadic pastoralists from anthropology, demography, genetics and medicine. They focused upon the ecology and population biology of contemporary herding groups from Africa, Asia, Europe, and the Mi...

Internationally, the population is ageing and people are living well, longer. In Australia, extended travelling has gained popularity among older Grey Nomads due to time and opportunity post retirement. However, there is limited research available focusing on older Australians' health while travelling. This paper reports the qualitative phase of a larger mixed-method project that explores the e...

Organisms often exhibit behavioral or phenotypic diversity to improve population fitness in the face of environmental variability. When each behavior or phenotype is individually maladaptive, alternating between these losing strategies can counter-intuitively result in population persistence-an outcome similar to the Parrondo's paradox. Instead of the capital or history dependence that characte...
