regional vegetation plays an important role in modeling ecosystem changes and conservation. meteorological drought indices which are directly obtained from such meteorological data as precipitation can't be useful in drought monitoring if those data are absence. therefore, remote sensing techniques may provide an efficient technique for drought monitoring. in this study, the values of norm...

Drought is a natural occurrence that has far-reaching and important consequences for the global economy, environment, industry, communities. In recent years, drought-like conditions have emerged in Nagaland as result of insufficient rains climate change, notably farmers, who faced worm-infested crops dried-up fields waterways. Therefore, quantitative examination drought condition vital early de...

The acquisition of new genetic traits by horizontal gene transfer and their incorporation into preexisting regulatory networks have been essential events in the evolution of bacterial pathogens. An example of successful assimilation of virulence traits is Salmonella enterica, which acquired, at distinct evolutionary times, Salmonella pathogenicity island 1 (SPI-1), required for efficient invasi...

INTRODUCTION Ischemia/reperfusion (IR) injury, often associated with liver surgery, is an unresolved problem in the clinical practice. Spironolactone is an antagonist of aldosterone that has shown benefits over IR injury in several tissues, but its effects in hepatic IR are unknown. OBJECTIVE To evaluate the effect of spironolactone on IR-induced damage in liver. MATERIALS AND METHODS Total...

BACKGROUND AND PURPOSE In 1991 we developed the Stroke Prognosis Instrument (SPI-I) to stratify patients with transient ischemic attack or ischemic stroke by prognosis for stroke or death in 2 years. In this article we validate and improve SPI-I (creating SPI-II). METHODS To validate SPI-I, we applied it to 4 test cohorts and calculated pooled outcome rates. To create SPI-II, we incorporated ...

Software process improvement (SPI) is a current topic in software engineering community. Most organisations, in order to maintain their competitive edge, plan or are in progress to apply SPI with the desired results of predictability in the software development considering time, cost, and quality. SPI effort can take many forms, e.g. it can be based on a road map like Software CMM, SPICE, ISO90...

In this paper we present survey data characterizing the implementation of SPI in 85 UK companies. We aim to provide SPI managers with more understanding of the critical success factors of implementing SPI. We present an analysis of the critical implementation factors identified in published case studies. We use a questionnaire to measure the use of these factors in ‘typical’ software companies....

Abstract The use of artificial neural networks as a tool to forecast droughts in Sri Lanka is presented. Predictions were made using the Standardized Precipitation Index (SPI) as the drought monitoring index. Monthly rainfall recorded at 13 climatological stations covering both the wet and dry zones over a long time period have been used as the input to train and test the neural networks. The a...

Resumo Este trabalho teve como objetivo avaliar a variabilidade espaço-temporal do índice Padronizado de Precipitação (SPI), forma identificar períodos escassez/excesso hídrica (o) na Sub-Bacia Choró no Estado Ceará. Para tanto, trabalhou-se com uma série histórica dados pluviométricos para o período 1974 2018 e SPI nas escalas 3, 6, 12 24 meses. Uma acentuada interanual foi observada, apontand...

In this paper we present findings from our empirical study of software process improvement (SPI) implementation. We aim to provide SPI practitioners with insight into designing appropriate SPI implementation initiatives in order to achieve better results. Thirty-four interviews were conducted with Australian practitioners. Three SPI implementation issues were investigated: reasons for embarking...
