Particulate organic matter (POM) is an important source of energy in aquatic systems, where decomposition rates have traditionally been studied using the litter-bag technique. However, this method has limitations for estimating in situ decomposition rates, especially for fine particles. In this study the litter-bag technique is combined with measurements of microbial enzyme activities to estima...

[1] New images from the Lunar Reconnaissance Orbiter Camera show the distribution and geological relations of the Sculptured Hills, a geological unit widespread in the highlands between the Serenitatis and Crisium basins. The Sculptured Hills shows knobby, undulating, radially textured, and plains-like morphologies and in many places is indistinguishable from the similarly knobby Alpes Formatio...

They naturally found in coastal, estuarine and marine environment world wide (Letchumanan et al., 2014; Raghunath, 2014). Vibrionaceae have primarily been investigated due to their pathogenic potential to humans and aquatic animals and can be transmitted to humans via infected water or through fecal transmission. Several species of Vibrio have been implicated with disease in fishes (Elhadi et a...

Instant Messaging (IM) is a service defined in RFC 2778 [6] that allows users to send and receive typically short, often textual messages in near real-time. The IETF has defined a generic URI used to identify an IM service for a particular resource: the ’im:’ URI scheme (defined in RFC 3861 [4]). RFC 3861 [4] also defines rules for discovering service running specific protocols, such as SIP (th...

84.6% of touching digit strings have only two digits touching, 12.3% have three digits touching, and 3.1% have more than three digits touching. We present a multiexperts approach to recognize touching digit pairs (TDP) and touching digit triples (TDT). We combine holistic and traditional segmentation methods. 25,686 TDP training samples and 2778 TDP testing samples collected from USPS mail are ...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
