Although eastern Asia (EAS) and eastern North America (ENA) have similar climates, plant species richness in EAS greatly exceeds that in ENA. The degree to which this diversity difference reflects the ages of the floras or their rates of evolutionary diversification has not been quantified. Measures of species diversity that do not incorporate the ages of lineages disregard the evolutionary dis...

The Bose (also Baise) Basin in Guangxi, southern China is well known for the presence of Paleolithic bifacially worked implements. The Bose Basin handaxes came to the attention of the international scientific community primarily for two reasons: 1) the age at 803 ka (thousands of years), places it at the Early to Middle Pleistocene transition; and 2) the presence of bifaces tests the validity o...

All reform countries in Central and Eastern Europe require a rapid and comprehensive restructuring of their public pension schemes for macroand microeconomic reasons. The paper argues that pension reform, economic restructuring, and the growth options for these countries are closely related, and that by pursuing a reform which is at least partially directed towards private and funded pensions, ...

A common theme in recent landscape studies is the comparison of riparian and watershed land use as predictors of stream health. The objective of this study was to compare the performance of reach-scale habitat and remotely assessed watershed-scale habitat as predictors of stream health over varying spatial extents. Stream health was measured with scores on a fish index of biotic integrity (IBI)...

The aim of this preliminary study was to estimate the proportions of seropositive horses on infected premises (IPs) in order to assess the attack risk of the disease. Logistic regression analyses were conducted to evaluate the differences in attack risks between enterprise sizes and predefined spatial clusters/regions. The average attack risk experienced during the outbreak was 96.88% (median 1...

The pathological findings in three cases of equine phycomycosis in Costa Rica are described. Two cutaneous (Pythium sp) and one nasal lesion (Conidiobolus) were observed.

This paper gives a brief description about some routing protocols like EEE LEACH, LEACH and Direct Transmission protocol (DTx) in Wireless Sensor Network (WSN) and a comparison study of these protocols based on some performance matrices. Addition to this an attempt is done to calculate their transmission time and throughput. To calculate these, MATLAB environment is used. Finally, on the basis ...

Variation in the body size of wild Culiseta morsitans collected from Massachusetts was examined. No significant size variation was detected at any time during the collection period, nor was there a significant size difference between parous and nulliparous mosquitoes. We conclude that size variation in this species does not affect survivorship, an important aspect of vectorial capacity.

Localitatea este comportamentul (auto-organizare structurala) a unei colectivităţi in jurul unei origini. Localitatea de grup este comportamentul unei colectivităţi determinat de anumite proprietăţi de grup, de exemplu simetriile unor figuri plane finite. Localitatea de grup este un alt punct de vedere asupra localităţii. Exprimând interconectarea ca model de colectivitate, demonstrăm că dihoto...

The emergence of the West Nile virus (WNV) in the northeastern United States has drawn emphasis to the need for expanded arbovirus surveillance in Connecticut. Although the state of Connecticut began a comprehensive mosquito-screening program in 1997, only since 1999 have there been efforts to determine the prevalence of arboviruses in bird populations in this state. Herein, we report on our re...
