In this study, a zinc selenide crystal (7 1 cm, 45 ) with a refractive index of 2.4 at 1000 cm −1, a density of 5.27 gcm −3, and a transmission range of 20,000–650 cm −1, was used. All spectra obtained represented an average of 100 scans, over the wavelength range of 4000–600 cm −1, and required 3–4 min for acquisition. 2014/10/1This study is one of the first to use a high throughput sequencing technique to compare the bacterial and fungal microbiome recovered from collocated bioaerosol samplers that included: a BioSampler (BIO) (SKC Inc., Eighty Four, PA), a button sampler (BS

Vanrolleghem But, what is grit? •No existing standard definition of grit •General definition used: Grit is traditionally defined as inorganic particles larger than 0.21 mm (65

Graphene oxide (GO) films with two-dimensional structure were successfully prepared via the modified Hummer method. It is proven that redox method is a promising way to synthesize GO films on a large scale. Comprehensive characterizations of the properties of GO films were conducted. TEM and DFM analyses showed that GO sheets prepared in this study had single and double lamellar layer

BACKGROUND: True arterial blood samples are essential in making clinical decisions for respiratory patients. Previous studies using only the Portex Pro-Vent arterial sampler have shown a significant difference between arterial and venous filling times. The goal of this study was to determine whether there is a statistically significant difference between sampler filling times measured at a

Operating Principle The Ogawa Passive Sampler contains two gas collection pads in its dual-inlet configuration. The pads are 14.5 mm in diameter, and are specially coated to react chemically with a selected gas or gases. Analysis of the collection pads takes

sampler described in this study (Fig. 4A) showed high cyanobacterial abundance close to the water surface of the canal at 09:00 while the C-PC profiles at 12:00, 16:00 and 24:00 showed a downward vertical movement pattern of cyanobacteria. Such vertical

Aerosol Research Since concentrated aerosols are sometimes found in the workplace and have been shown to result in a number of diseases, NIOSH has devoted a significant portion of their research to the study of aerosols. This work initially focused on pressing

Accurate characterization of particulate matter (PM) exposure in young children is difficult, because personal samplers are often too heavy, bulky or impractical to be used. The Pretoddler Inhalable Particulate Environmental Robotic (PIPER) sampler was developed

In our work to study and promote students' emerging covariational reasoning abilities, we have found that the ability to move flexibly between mental actions 3, 4 and 5 is not trivial for students. We have also observed that many precalculus level students only employ Mental Action 1 and Mental Action 2 when asked to construct the graph of a dynamic function situation.

2020/7/20Abstract The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were (1) the preliminary postcruise evaluation of the tools and measurement systems that were used during ODP Leg 204 to study hydrate deposits on Hydrate Ridge, offshore Oregon from July through September 2002; and (2) the preliminary study of the hydrate-bearing core samples

Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions. This type of investigation is called a site
