Transparent exopolymer particles (TEP) are planktonic, organic microgels which play significant roles in cycling of carbon and trace elements, aggregation of particles, feeding and accommodating microbes as well as development of biofilms. However, few studies are available on the mechanism of TEP formation in various water environments. Here we investigate the formation of TEP with alginate bl...

Secondary tracheoesophageal puncture (TEP) placement in patients with severe limitations in neck extension is challenging. Visualization of the hypopharynx with traditional rigid endoscopy may not be possible. We report using the C-MAC (Karl Storz, Tuttlingen, Germany) video laryngoscope to successfully place a secondary TEP in patient with severe radiation fibrosis at a tertiary referral cente...

The high abundance of transparent exopolymer particles (TEP) in marine and freshwater greatly affects particle dynamics. TEP act as glue for colliding particles and form the matrix in aggregates, thereby altering aggregation dynamics. We studied the sinking behavior of freshly produced, particle-free TEP and of aggregates composed of TEP and latex spheres in a laboratory using water collected f...

Synthesis and structural characterization of 1,4,2-oxazaphosphepines is described. The 1,4,2-oxazaphosphepines were obtained from reaction of chiral 1,3-benzoxazines with dichlorophenylphosphine or triethyl phosphite. The configuration of some of these compounds was stablished by X-ray analysis.

INTRODUCTION Endoscopic surgical repair of inguinal hernia is currently conducted using 2 techniques: the totally extraperitoneal (TEP) and the transabdominal (TAPP) hernia repair. The TEP procedure is technically advantageous, because of the use of no mesh fixation and the elimination of the peritoneal flap, leading to less postoperative pain and faster recovery. The drawback is that TEP is no...

Pollution of the marine environment is an emerging threat. Nowadays, engineered nanoparticles (<100 nm) such as zinc, copper and silver are widely used antimicrobial agents, therefore often present in daily-life products. Consequently, demand production expected to increase. Here, we specifically focus on (AgNP). Once released into environment, AgNPs pose obvious ecotoxicological risk, p...

Positive or negative plant growth effects due to soluble organic biochar compounds are not well understood. Increasing quantities (0 g, 0.5 2.5 and 5 g) of four different biochars were extracted with 0.1 M HCl, which separated marked as W, X, Y, Z. Corn rice seeds treated extract solution. The straw Y Z solutions positively affected corn germination, while the cotton solution negatively it. Whe...

Coccolithophores, among which Emiliania huxleyi is the most abundant and widespread species, are considered the most productive calcifying organism on earth. The export of organic carbon and calcification are the main drivers of the biological CO2 pump and are expected to change with oceanic acidification. Coccolithophores are further known to produce transparent exopolymer particles (TEP) that...

Measurements of thermoelectric transport coefficients yield important information regarding fundamental properties of a system in addition to the information supplied from the electronic transport measurements. In this thesis we report gate dependent and temperature dependent conductance (G) and thermoelectric power (TEP) measurements made in three different basic nanomaterials: single-walled n...
