landslides are natural disasters that annually inflict great damages to public and private properties which may associate with loss of life. in recent decades, research on developing methods for predicting the time of landslide has been one of the significant attempts made by scientists. since in some type of material, landslides are preceded by undetectable movements that cannot be recorded an...

an important problem in performance evaluations of irrigation systems is the difficulty of the determining share of structural and operational elements and determining improvement solutions. in most studies, the combined impact of structural and operational elements on the performance of irrigation systems is assessed. some researchers try to separate the effects of structural and operational e...

Long-term measurements of ecological effects of warming are often not statistically significant because of annual variability or signal noise. These are reduced in indicators that filter or reduce the noise around the signal and allow effects of climate warming to emerge. In this way, certain indicators act as medium pass filters integrating the signal over years-to-decades. In the Alaskan Arct...

We define and analyze here three attributes associated with each scientific article: ‘topic’, ‘method’ and ‘impact’. Nearly every article referenced in the PubMed database has a list of keywords reflecting its content: chosen from more than 20,000 MeSH terms and more than 150,000 chemical names [2]. We use MeSH terms and chemical names as indicators of an article’s topic and method, respectivel...

We have established two classification rules that statistically accurate allow to separate carcinogenically active chemical compounds from inactive chemical compounds. The electronic and information properties of molecules are used as molecular descriptors. The threshold values of descriptors that characterize and determine the presence or absence of carcinogenic properties of chemical compound...

Data-mining of Reaxys and network analysis of the combined literature and in-house reactions set were used to generate multiple possible reaction routes to convert a bio-waste feedstock, limonene, into a pharmaceutical API, paracetamol. The network analysis of data provides a rich knowledge-base for generation of the initial reaction screening and development programme. Based on the literature ...

The environment has emerged as an important determinant of the performance of the modern chemical industry. Process engineering in the 21 century needs to evolve to include environmental issues as part of the design objectives, rather than as constraints on operations. A frequently cited objection to the use of quantitative indicators of environmental performance in product and process design i...

Few experiments in the coastal plain region of the southeastern United States have reported the effect of long-term tillage and tillage intensity on chemical soil quality indicators. The purpose of this study was to determine the 17-year influence of four tillage systems on chemical soil quality indicators in a Benndale fine sandy loam (coarse-loamy, siliceous, semiactive, thermic, Typic Paleud...

the bahía blanca estuary, located at the atlantic coast of argentina, includes a governmental nature reserve to protect biodiversity, lands and water; however, as the process of industrialization and urbanization is stepping rapidly at the neighbouring area, the potential increase in contaminant loads is a serious concern. after several contaminants surveys at the estuary, no single study has b...
