The Extreme Programming software development methodology relies heavily on the colocation of the team members. Outsourcing and teleworking is becoming more common nowadays, meaning that XP practitioners need to adapt their daily XP practices for a distributed setting. In most cases the distributed teams use (existing) tools that is a direct translation of a practice without thinking about inter...

In this paper, we analyzed the streamflow droughts based on the Percent of Normal Index (PNI) and clustering approaches in the Kurdistan Province, Iran, over the 1981-2010. The Kolmogorov-Smirnov (K-S) test was considered for streamflow time series and the results of K-S test indicated that streamflow time series did follow the normal distribution at the 0.05 significance level. Generally, the ...

System Metaphor is one of the key practices of Extreme Programming (XP). Unfortunately, the System Metaphor practice is poorly understood, and is the practice XP teams most commonly choose to ignore. In this paper, we provide a small collection of patterns that teams can use to develop metaphors for their systems, and for evaluating system metaphors. We hope these patterns will encourage Extrem...

BACKGROUND There is an increasing interest in the study of microorganisms that inhabit extreme environments for reasons that vary from gaining insight into the origin of life to the searching of new biotechnological applications. AIMS In this work, we studied the tolerance of fungi isolated from the Aguas Agrias Stream (AAS; Tharsis, Huelva, Spain), an acidic metal-rich environment, to a cult...

Extremophilic organisms are primarily prokaryotic (archaea and bacteria), with few eukaryotic examples. Extremophiles are defined by the environmental conditions in which they grow optimally. The organisms may be described as acidophilic (optimal growth between pH 1 and pH 5); alkaliphilic (optimal growth above pH 9); halophilic (optimal growth in environments with high concentrations of salt);...

Rhizosphere microorganisms are a heterogenous group of bacteria, including plant growth promoting bacteria, which can improve extent or quality of plant growth direct and indirect. Generally large array of bacteria, including species of Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus and Serratia have been reported to enhance p...

Muhammad Rizwan [email protected] Department of Computer Engineering University of Engineering and Technology Taxila, Pakistan Abstract: Atomic commit protocols are used where data integrity is more important than data availability. Two-Phase commit (2PC) is a standard commit protocol for commercial database management systems. To reduce certain drawbacks in 2PC protocol people h...
