We investigated the effects of thiamine on sake production. Thiamine had similar effects on small-scale brewing tests at rice polishing ratios from 70% to 40%.We carried out the tests at various stages of thiamine addition. It was clear that the effects were increased by thiamine addition in early phases. We were able to produce low alcohol sake with high fragrance. It was apparent that diacetyl was not generated in thiamine-added brewing tests.In the thiamine-added tests to yeast cultivation, the results were similar in the case of moromi mash.As with the brewing of sake yeast, the thiamine had similar effects on sake production with the use of wine yeast.

Background:Metabolic syndrome (MetS) is associated with an increased risk of ischaemic stroke, including silent brain infarction. No study has examined its association with the lacunar subtype. The present cross sectional study examined the relationship between MetS, its components and silent lacunar infarction (SLI) in middle aged subjects.Methods:We studied 2076 subjects aged 40–59 years with no history of stroke or clinical symptoms, who visited a health care facility for a routine health checkup and underwent brain MRI. MetS was defined according to the National Cholesterol Education Programme Adult Treatment Panel III report. A multiple logistic regression model was used to examine the associations between MetS and SLI while adjusting for age, gender, a past history of ischaemic heart disease and current smoking.Results:MetS was strongly associated with the presence of SLI (adjusted OR 6.52; 95% CI 4.30 to 9.90). Regarding MetS components, elevated blood pressure, impaired fasting glucose, hypertriglyceridaemia and large waist circumference were significantly associated with SLI, independent of an interrelationship between the components, while low high density lipoprotein cholesterol was not significantly associated.Conclusions:MetS was significantly associated with the prevalence of SLI in middle aged persons. Independent risk factors for SLI not only included elevated blood pressure and impaired fasting glucose, which are well known risk factors, but also hypertriglyceridaemia and large waist circumference.

The electric field changes in ELF to VLF were observed with a ball antenna in fair weather at Kochi (latitude 33.3°N, longitude 133.4°E) during 2003–2004. Some 376 Q bursts were obtained, seven examples of which are analyzed in the present study. The continuous frequency spectra of the Q bursts and the background noises from 1.0 Hz to 11 kHz are compared, and it was found that the Q bursts prevail over the background in the frequency range from 1 to 300 Hz. The surplus is 20 dB (in amplitude) near the fundamental mode frequency. The “W”‐type changes found in the initial portion of the Q burst waveforms are interpreted as the combined electromagnetic waveform of direct and antipodal waves from the causative lightning strokes. From the time intervals between the two waves, the source‐receiver distances are estimated as far as 19 Mm. The pulses to excite the Schumann resonances in the Q bursts are clearly identified.

Abstract High‐performance top‐gate ZnO thin‐film transistors (TFTs) for AM‐LCDs have been developed. Sputtered ZnO was used as an active channel and silicon nitride (SiNx) deposited by plasma enhanced chemical vapor deposition (P‐CVD) was used as a gate insulator. Field effect mobility and threshold voltage of the ZnO‐TFT are 50.3 cm 2 /V⋅sec and 1.1 V, respectively. We first demonstrated a 1.46″ diagonal AM‐LCD driven by ZnO‐TFTs.

An investigation of the growth mechanisms, electronical and structural properties, and field emissions of carbon films obtained by chemical vapour deposition showed that field emissions from films composed of spatially oriented carbon nanotubes and plate-like graphite nanocrystals exhibit non-metallic behaviour. The experimental evidence of work function local reduction for carbon film materials is reported here. A model of the emission site is proposed and the mechanism of field emission from nanostructured carbon materials is described. In agreement with the model proposed here, the electron emission in different carbon materials results from sp3-like defects in an sp2 network of their graphite-like component.

Lindbladione (1), 7-methoxylindbladione (2), and 6, 7-dimethoxylindbladione (3) have been isolated from a myxomycete Lindbladia tubulina and their structures were elucidated by spectral data.

We study systems with parity invariant contact interactions in one dimension. The model analyzed is the simplest nontrivial one --- a quantum wire with a point defect --- and yet is shown to exhibit exotic phenomena, such as strong vs weak coupling duality and spiral anholonomy in the spectral flow. The structure underlying these phenomena is SU(2), which arises as accidental symmetry for a particular class of interactions.

We first give the solution for the local approximation of a four parameter family of generalized one-dimensional point interactions within the framework of non-relativistic model with three neighboring $\delta$ functions. We also discuss the problem within relativistic (Dirac) framework and give the solution for a three parameter family. It gives a physical interpretation for so-called $\epsilon$ potential. It will be also shown that the scattering properties at high energy substantially differ between non-relativistic and relativistic cases.
