The expansion of selective logging in tropical forests may be an important source of global carbon emissions. However, the effects of logging practices on the carbon cycle have never been quantified over long periods of time. We followed the fate of more than 60 000 tropical trees over 23 years to assess changes in aboveground carbon stocks in 48 1.56-ha plots in French Guiana that represent a ...

Up till now, there is no production logging data interpretation module in CIFLog, which is the 3rd generation well-logging software platform in China. So the situation has a strong impact on its promotion and utilization. In this paper, firstly, the authors introduce the characteristics of the existing and mature logging interpretation software, and design the data interpretation module functio...

This paper presents a new algorithm for supporting fault tolerant objects in distributed object oriented systems. The fault tolerance provided by the algorithm is fully user transparent. The algorithm uses checkpointing and message logging scheme. However the novelty of this scheme is in identifying the checkpointing instances such that the checkpointing time will not aaect the regular response...

1. INTRODUCTION Current databases need logging and recovery to maintain the correctness properties of transactions and consistency of the database under failures. Also, logging and recovery have tremendous performance implications. While there has been a lot of work that deals with logging and recovery algorithms for traditional disk resident databases ([1, 2, 3, 4, 5]) and Main Memory Database...

Logging of input and output variables is very useful in computational steering. In this paper we describe how we added logging functionality to a computational steering environment developed at CWI. We show how a 2D interface can be augmented with logging by using the third dimension for the display of the logged variables. The user specifies which graphical representations of variables must be...

PROBLEM It is well documented that logging is one of the most dangerous occupations and industries in which to work, and trees fellers are at greatest risk of injury. The objective of this study was to determine whether West Virginia (WV) logging companies experienced a reduction in injuries after beginning to use feller-bunchers (tree cutting machines, which replace some of the work done with ...

The Indian Punjab has been heralded for its technical achievements but increasingly criticized for leveraging its success on the environment. Irrigation has been one of the main pillars of the Punjab's Green Revolution. The availability of water has pushed rice and wheat productivity to new heights. Cheap water policies have enabled farmers to exploit groundwater. Water tables are shrinking in ...

Introduction Hydrogeologic investigations are often hampered by insufficient information about the site-specific hydrostratigraphic features that control ground water flow and solute transport. Field and modeling studies in a wide variety of geologic settings have shown the importance of a detailed description of aquifer heterogeneity for applications ranging from prediction of contaminant tran...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...
