To the Editor: Predictable rhythmic fluctuations, especially circadian, have been observed in a wide variety of physiologicai and psychological functions. Abno~a~ities of circadian patterns have been documented in people with depression, including a tendency for maximal severity of depression in the morning; however, patients with anxiety or mixed depression/anxiety report a tendency for sympto...

We present JHKS near-infrared CCD photometric study for the Galactic open clusters NGC 1641 and NGC 2394. These clusters have never been studied before, and we provide, for the first time, the cluster parameters; reddening, distance, metallicity and age. NGC 1641 is an old open cluster with age 1.6 ± 0.2 Gyr, metallicity [Fe/H]= 0.0 ± 0.2 dex, distance modulus (m−M) 0 = 10.4 ± 0.3 mag (d= 1.2± ...

Tetrastichus planipennisi (Hymenoptera: Eulophidae) is a gregarious larval endoparasitoid from China that is being released in the United States as a biocontrol agent of the emerald ash borer (Agrilus planipennis Fairmaire), an exotic beetle responsible for widespread ash mortality. The developmental time of immature stages, adult longevity, reproductive age, oviposition rate, and realized fecu...

The sensory ecology of predator detection by prey has been little studied for any arthropod prey predator system, in contrast to the sensory ecology of prey finding by predators. The aim of this study was to quantify the foraging signals produced by the parasitoid Sympiesis sericeicornis (Hymenoptera: Eulophidae) and the sensory ecology of enemy detection and the avoidance behaviour of the leaf...

Information technology has had a significant impact on business operations and allowed the emergence of new business models. These IT-enabled processes and businesses however depend on secure information systems which need to be managed. The management of information systems security (ISS) is a highly dynamic and complex task due to constant change in the information technology domain. In this ...

It is imperative for organizations to use Information Security Management System (ISMS) to effectively manage their information assets. ISMS starts with a set of policies that dictate the usage of computer resources. It starts with the “21 essential security controls” of ISO 27001, which give the basic standard requirements of information security management. Our research is concerned with the ...

The Myxozoa Grassé, 1970 infecting fish is an important pathogenic group having a worldwide distribution. Among these parasites the monotypic genus Meglitschia Kovaleva, 1988 has been reported infecting the gallbladder (Gb) of a marine fish from the New Zealand fauna [1,2] and a freshwater fish from Brazil, collected in a tributary of Amazon River [3]. The teleostean host (Eugerres brasilianus)...

The dispersal characteristics of a biological control agent can have direct implications on the ability of that agent to control populations of a target host. Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a parasitic wasp native to eastern Asia that has been introduced into the United States as part of a classical biological control program against the emerald ash borer Agrilus pl...
