The development of satellite-derived datasets has greatly facilitated large-scale ecological studies, as in situ observations are spatially sparse and expensive undertakings. We tested the efficacy of using satellite sea surface temperature (SST) collected by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and local water temperature collected from NOAA buoys and onshore stations t...

Logging is a particular storage semantic involving speciic storage mechanisms, e.g. nding the log end or sequencing through a log. This paper presents the main logging techniques issues through a study of four existing logging systems implemented as independent storage systems: Clio, Camelot DLF, Ki t L o g and Sprite LFS. It aims to provide a clear view of problems and actual solutions.

Permeability is arguably the most important property in evaluating fluid flow in the reservoir. It is also one of the most difficult parameters to measure in field. One of the main techniques for determining permeability is the application of Nuclear Magnetic Resonance (NMR) logging across the borehole. However, available correlations in literature for estimating permeability from NMR data do n...

Logging contract systems are in need of change—they are leading to environmentally destructive exploitation and poor returns to landowners. The reaction has been to ban logging, thus giving subsidies to domestic timber processing industries. Export taxes are an inefficient and inequitable means of timber revenue distribution. The logging contract needs to be changed to allow landowners and gove...

Nuclear logging is one of most important logging services provided by many oil service companies. The main parameters of interest are formation porosity, bulk density, and natural radiation. Other services are also provided from using complex nuclear logging tools, such as formation lithology/mineralogy, etc. Some parameters can be measured by using neutron logging tools and some can only be me...

Logging activities within the forestry sector commonly take several seasons for each region. Throughout each season, the workers directly involved within the logging activities are hosted at an accommodation close to the current logging location. However, the next cities or villages are usually far away. A common solution to this problem is the construction of logging camps that contain the com...

In the recovery of failed processes in a distributed program, causal logging schemes offer several benefits. These benefits include no rollback of unfailedprocesses and simple approaches to output commit. Unfortunately, previous approaches to the recovery of multiple simultaneous failures require that the distributed execution be blocked or that recovering processes coordinate. The latter requi...

Over 20% of the world's tropical forests have been selectively logged, and large expanses are allocated for future timber extraction. Reduced-impact logging (RIL) is being promoted as best practice forestry that increases sustainability and lowers CO2 emissions from logging, by reducing collateral damage associated with timber extraction. RIL is also expected to minimize the impacts of selectiv...

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 ...
