Intermittent streamflow is a common occurrence in permeable catchments, especially where there are pumped abstractions to water supply. Many rainfall-runoff models are not formulated so as to represent ephemeral streamflow behaviour or to allow for the possibility of negative recharge arising from groundwater pumping. A groundwater model component is formulated here for use in extending existin...

In this paper, we explore the challenge of Password Fatigue, which is essentially the difficulty involved with having too many passwords to remember and manage. The systemic failure to recognize the problem in the context of people's time and attention results in numerous security exposures due to bad habits and inappropriate shortcuts. To address this issue, we examine the concept of ephemeral...

The ecological principle of competitive exclusion states that species competing for identical resources cannot coexist, but this principle is paradoxical because ecologically similar competitors are regularly observed. Coexistence is possible under some conditions if a fluctuating environment changes the competitive dominance of species. This change in competitive dominance implies the existenc...

Limited information is currently available on how sediment transport affects rill flow resistance and the influence of hydraulic variables, as stream power, capacity for flows. In this paper, measurements variables (flow depth, channel slope, mean velocity, Reynolds number, Froude Darcy–Weisbach friction factor) carried out by Ban et al. (Measurement ephemeral gully velocities their model expre...

The Index Calculus Method (ICM) is the most effective method to solve the Discrete Logarithm Problem (DLP). Many public key cryptosystems are based on the intractability of DLP. The DLP defined over a prime field Zp of random prime (p) is considered in the present study. The paper presents a variant of ICM on integer field when the factors of the group are known and small. This is achieved thro...

Abstract This study investigated the influence of dissolved organic matter (DOM) additions on phosphate sorption kinetics iron-rich sediments (39–50% hematite and goethite) from an ephemeral stream in arid Pilbara region sub-tropical northwest Australia. While is known to be strongly influenced by sediment mineralogy as well interactions with DOM, mechanisms significance DOM P-release high capa...

The ability for Tangible User Interfaces to enable the intuitive control of existing systems and adapt to individual users’ usage scenarios remains an area of development. Previous research in customizable tangible interfaces has focused primarily on the offline creation by the original system developer, instead of offering extensibility to the end user. This paper presents our system to suppor...

The fauna communities of ephemeral pools in southern Chile are characterized by heterogeneity of crustacean taxa; nevertheless, no detailed studies exist of their community structure. The aim of the present study was to analyze the crustacean community structure in two groups of ephemeral pools (Puaucho and Nigue pools) in the coastal zone of the Araucanía region. A correlation matrix was made ...

Bovine ephemeral fever (or 3-day sickness) is an acute febrile illness of cattle and water buffaloes. Caused by an arthropod-borne rhabdovirus, bovine ephemeral fever virus (BEFV), the disease occurs seasonally over a vast expanse of the globe encompassing much of Africa, the Middle East, Asia and Australia. Although mortality rates are typically low, infection prevalence and morbidity rates du...

bovine ephemeral fever (bef) flared up in a dairy farm with 2097 animals. the disease started in september, 2006, with daily means of environmental temperature (et) and relative humidity (rh) of 23.8 ºc and 37%, respectively, and ended after 48 days with et and rh of 16.2 ºc and 68%, respectively. in this outbreak, the age of affected animals was above 10 months and the morbidity rate was 13.07...
