A series of azomethine esters,3-hydroxy-4-{[（4-iodophenyl）imino]methyl}phenyl alkanoates possessing even number of carbon atoms at the terminal alkanoyloxy chain（C_（n-1）H_（2n-1）COO-,n = 4,6,8,10,12,14） was synthesized.n-Butanoyloxy was found non-mesogenic,whilst n-hexanoyloxy to n-tetradecanoyloxy exhibited enantiotropic smectic A phase with fan-shaped *** was found that the length of terminal alkanoyloxy chain influenced the mesomorphic properties.

Echinococcosis is a global and zoonotic helminthic disease caused by Echinococcus sp. A 24-year-old woman, coming from Bolivia two years before, was diagnosed as cystic echinococcosis (CE) by unstained wet mount and cytological findings through aspiration cytology from the liver, suggested as liver abscess by diagnostic images. The patient was classified as CE1, smaller than 5 cm, and was diagnosed as P1N0M0, stage I. The phylogenetic trees of Echinococcus spp., based on cox1 genes showed that the isolates on the patient belonged to E. ortleppi. The patient was conservatively treated with two courses of albendazole therapy. E. ortleppi has been reported to be in regions including Latin America, except with Japan. Although the patient came from Bolivia before two years, this is the first case report of E. ortleppi from liver echinococcosis in Japan.

The mid-infrared absorption spectra of geometrically frustrated hydroxyl cobalt halogenides Co2 （OH）3 CI and Co2 （OH）3Br are measured by FTIR spectrometers, and the stretching vibrational modes of hydroxyl groups are found to be 3549 cm-1 and 3524 cm-1 respectively. Through finding their true terminal O II group stretching vibration frequencies, we obtain 107cm-1 and 99cm-1 red shift caused by the corresponding O-H...Cl and 0 H...Br hydrogen bonds. Rarely reported trimeric hydrogen bonds （Co3≡O H）3….C1/Br are pointed out to demonstrate the relative weakness of this kind of hydrogen bond which may have a critical effect on the lattice symmetry and magnetic structures.

The discovery of the water channel aquaporin has greatly expanded our understanding of the regulation of the water permeability of biological membranes。The atomic structure of aquaporin-1 (AQP1) demonstrated how aquaporin is freely permeated by water but not protons and provided marked insight into several human disorders, 13 mammalian aquaporins have been identified, each with a distinct distribution, and these are selectively permeated by water or water plus glycerol。Aquaporins are suspected in numerous pathological conditions such as brain edema, diabetes mellitus。Knowledgeof structure, regulation and function of aquaporins may provide insight into the development of new therapeutics through appropriate drug design。

In this study, we apply the optical flow method to the time-series shadowgraph images of impinging jets using a high-speed video camera with high spatial and temporal resolution. This image analysis provides quantitative velocity vector fields in the object space without tracer particles. The analysis results clearly capture the details of the coherent vortex structure and its advection from the shear layer of the free jet. Although the results still leave challenges for the quantitative validation, the results show that this analysis method is effective for understanding the details of the physical phenomenon based on the quantitative values extracted from the shadowgraph images.

We fabricated YBa2Cu3O7–d bulk ceramics with a domestic microwave oven and investigated the effect of pressure at the press procedure. If the pressure was not high enough, the ratio of BaCuO2 phase became large, estimated from x-ray diffraction (XRD) measurements. We found that the pressure should be 700 kgf/cm2 at least in order to suppress the BaCuO2 phase.

Compressive force sensors or pressure sensors are indispensable to tactile sensors in humanoid robots. It is investigated that low-cost electro-conducting rubber sheets are applied to the force sensor, of which the biggest problem is its poor reproducibility. It was found that the aluminum deposition by a vacuum evaporation method shows excellent characteristics but suffers deterioration by a radiation heating effect. The aluminum electrode was deposited by a sputtering method, known to have an advantage of a low-temperature method, and the reproducibility of the output was improved.
