A study has been made of the atmospheric-pressure Penning ionization (APPeI) of aliphatic hydrocarbons (pentane, hexane, heptane, and octane) with long-lived rare gas atoms (Rg*). The metastable rare gas atoms (He*, Ne*, Ar* and Kr*) were generated by the...

Isolation and characterization of a tetrachloroethylene dechlorinating bacterium, Clostridium bifermentans DPH-1.

A tetrachloroethylene (PCE)-degrading gram-positive, endospore forming, anaerobic bacterium, strain DPH-1, was isolated from a contaminated site. The organism was identified as Clostridium bifermentans by 16S rRNA gene sequence analysis and based on its physiological characteristics. Strain DPH-1 could dechlorinate...

Anaerobic degradation of cis-1,2-dichloroethylene and vinyl chloride by Clostridium sp. strain DC1 isolated from landfill leachate sediment.

The bacterial community structure of anaerobic enrichment cultures that are capable of degrading both cis-1,2-dichloroethylene (cis-DCE) and vinyl chloride (VC) and isolation of the organism responsible for the degradation were investigated. Denaturing gradient gel electrophoresis (DGGE) of a PCR-amplified...

Measuring the frequency of a Sr optical lattice clock using a 120 km coherent optical transfer.

Opt Lett. 2009 Mar 01;34(5):692-4. doi: 10.1364/ol.34.000692.

We demonstrate a precision frequency measurement using a phase-stabilized 120 km optical fiber link over a physical distance of 50 km. The transition frequency of the (87)Sr optical lattice clock at the University of Tokyo is measured to be...

Computed tomography-guided drainage for large pulmonary bullae.

Interactive cardiovascular and thoracic surgery

Takizawa H, Kondo K, Sakiyama S, Monden Y.
PMID: 17670238
Interact Cardiovasc Thorac Surg. 2004 Jun;3(2):283-5. doi: 10.1016/j.icvts.2003.12.007.

Patients with large pulmonary emphysematous bullae often present therapeutic problems because of their poor respiratory function. We performed computed tomography (CT)-guided drainage in two patients with large pulmonary bullae who were considered poor surgical candidates. This method could be...

Experimentally determined growth exponents during the late stage of spinodal demixing in binary liquid mixtures.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hobley J, Kajimoto S, Takamizawa A, Fukumura H.
PMID: 16486149
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Jan;73(1):011502. doi: 10.1103/PhysRevE.73.011502. Epub 2006 Jan 05.

Spinodal demixing was initiated in two systems, with critical and off-critical compositions, using nanosecond pulsed laser-induced temperature jumps (T-jumps) of various magnitude. In this way, deep quenches could be imposed on the systems. One system was the simple triethylamine...

Structural susceptibility of gas inclusion crystal to external gas pressure and temperature: force guide role of channel.

Dalton transactions (Cambridge, England : 2003)

Takamizawa S, Nakata E, Miyake R.

Dalton Trans. 2009 Mar 14;(10):1752-60. doi: 10.1039/b813178c. Epub 2009 Jan 12.

In order to investigate the methane-included condition in porous materials and its response to external stimuli, the methane adsorption state of a single-crystal adsorbent, [Cu(ii)(2)(bza)(4)(pyz)](n), was studied by single-crystal X-ray analysis and adsorption measurement as functions of temperature (90-298...

Atomic fountain clock with very high frequency stability employing a pulse-tube-cryocooled sapphire oscillator.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Takamizawa A, Yanagimachi S, Tanabe T, Hagimoto K, Hirano I, Watabe K, Ikegami T, Hartnett JG.

IEEE Trans Ultrason Ferroelectr Freq Control. 2014 Sep;61(9):1463-9. doi: 10.1109/TUFFC.2014.3060.

The frequency stability of an atomic fountain clock was significantly improved by employing an ultra-stable local oscillator and increasing the number of atoms detected after the Ramsey interrogation, resulting in a measured Allan deviation of 8.3 × 10(-14)τ(-1/2)). A...

Versatile Ferroelastic Deformability in an Organic Single Crystal by Twinning about a Molecular Zone Axis.

Ferroelasticity involves the generation of spontaneous strain in a solid by the application of mechanical stress. The phenomenon has been well-studied in metal alloys but relatively neglected in organic solid-state chemistry. Herein we present multiple discrete modes of mechanical...

It is well known that the prevalence of heterotopic pregnancies following assisted reproductive technology (ART) is much higher than among spontaneous pregnancies. Here, we illustrate a very rare case of bilateral simultaneous tubal pregnancies combined with intrauterine pregnancy (incomplete...
