Prevalence and genetic diversity of bartonella species isolated from wild rodents in Japan

Here, we describe for the first time the prevalence and genetic properties of Bartonella organisms in wild rodents in Japan. We captured 685 wild rodents throughout Japan (in 12 prefectures) and successfully isolated Bartonella organisms from 176 of the 685 rodents (isolation rate, 25.7%). Those Bartonella isolates were all obtained from the rodents captured in suburban areas (rate, 51.8%), but ...

Methane oxidation in water-spreading and compost biofilters

This study evaluated two biofilter designs to mitigate methane emissions from landfill vents. Water-spreading biofilters were designed to use the capillarity of coarse sand overlain by a finer sand to increase the active depth for methane oxidation. Compost biofilters consisted of 238-L barrels containing a 1: 1 mixture (by volume) of compost to expanded polystyrene pellets. Two replicates of ...

Mind bomb-1 is essential for intraembryonic hematopoiesis in the aortic endothelium and the subaortic patches

Intraembryonic hematopoiesis occurs at two different sites, the floor of the aorta and subaortic patches (SAPs) of the para-aortic splanchnopleura (P-Sp)/aorta-gonad-mesonephros (AGM) region. Notch1 and RBP-j are critical for the specification of hematopoietic stem cells (HSCs) in Notch signal-receiving cells. However, the mechanism by which Notch signaling is triggered from the Notch ...

Using Rn-222 to manage the air quality of air conditioned buildings in Hong Kong

This paper proposes a pragmatic methodology to manage the air quality of an air conditioned building as well as optimizing energy consumption during venting. Radon-222 (Rn-222) is used as a tracer to quantify the specific production rates and resultant losses of pollutants for which the information is important in indoor air quality management. A term, indoor pollutant inventory, is introduced ...

Characterizing scale- and location-dependent correlation of water retention parameters with soil physical properties using wavelet techniques

Understanding the correlation between soil hydraulic parameters and soil physical properties is a prerequisite for the prediction of soil hydraulic properties from soil physical properties. The objective of this study was to examine the scale- and location-dependent correlation between two water retention parameters ( and n) in the van Genuchten (1980) function and soil physical properties (sand ...

Limits of UV disinfection: UV/electrolysis hybrid technology as a promising alternative for direct reuse of biologically treated wastewater

Although UV irradiation represents an energy efficient disinfection method, bacterial regrowth in UV irradiated secondary effluents is a serious problem for their direct reuse (e.g., for domestic or irrigation purposes). The decrease of the lethal UV fluence caused by coverings (scaling and biofouling) on quartz sleeves of UV lamps and/or fluctuating specific water parameters (suspended solids, ...

Jökulhlaups and sediment transport in Watson River, Kangerlussuaq, West Greenland

For 3 years, during a 4-year observation period (2007–2010), jökulhlaups were observed from a lake at the northern margin of Russells Gletscher. At a gauging station located on a bedrock sill near the outlet of Watson River into Sdr Strømfjord, discharge and sediment transport was monitored during the jökulhlaups. The stage rose up to 5.3 m and a maximum discharge of ...

Digital Calibrator Accuracy Table for TEGAM 940 Series Thermocouple Calibrators

Have you ever tried to determine what the accuracy of a thermocouple calibrator is in degrees? Accuracy specifications are typically given as a percent of a reading ± a small Voltage; not in degrees. To help TEGAM users, we developed this table below to convert the 940 Series Thermocouple Calibrators' specifications into degrees. We used the maximum error for each 100°C increment of ...
