[en] Tests of penetration liquids normally used between 10 and 40⁰C have shown that the arrangement of operationaal conditions (penetration and revealing times) was not sufficient to maintain their sensitivity below 10⁰C, thereby confirming that this temperature is a limit below which such products cannot be employed. The results achieved with a penetrant and a tracer specially devised for low temperatures (SHERWIN B 305 + D100) are satisfactory between 0⁰C and 15⁰C

[en] Measurements of internal stress σ_i, anelastic strain ε_A and recovery rate γ were made in steady state creep of 2024 Al alloys over a wide range of stresses at temperatures between 260 deg C and 380 deg C, for the purpose of investigating the relations among the three parameters. Values of σ_i were obtained by the method of strain transient dip test, and those of ε_A and γ were determined from the results of sudden stress removal or reduction tests. As a main result, it is thought that the anelastic behavior and the recovery process are basically dependent on same deformation mechanisms. (Author)

[en] The diffusion-elastic technique (DE) was applied to measure the diffusivity D_H of hydrogen in the α-phase of the Pd/H system at 50deg C and to investigate the influence of boundary and initial conditions on derived value of D_H. The agreement between experimental curves and theoretical shapes and coincidence with available data indicate a good fit of the model to the chosen experimental regimes. High sensitivity of the DE-effect as compared to the Gorsky effect allows a close check of this fit significant for a correct interpretation of involved processes and results. (orig.)

[en] In the present paper preparation conditions for the formation of various types of uranyl gel, using the internal gelation route, are described. Various types of the gel can be prepared differing in their physico-mechanical properties. The research parameters were selected with respect to practical preparation conditions. The results of the paper represent an attempt to investigate systematically some of the basic chemistry problems of the gel process. (Auth.)

[en] In order to develop the commercial storage method of potatoes by irradiation combined with natural low temperature, two varieties of potatoes, Irish cobbler and Shimabara were stored at natural low temperature storage room (450x650x250cm; year round temperature change, 2-17 degC; 70-85% R.H.) on a batch scale followed by irradiation with optimum dose level. Irish cobbler and Shimabara were 100% sprouted after 3 months storage in control, whereas in 15Krad irradiated group, sprouting was completely inhibited at Irish cobbler for 9 months storage, and at Shimabara for 12 months. The extent of loss due to rot attack after 9 months storage was 6% in control, 6-8% in 10-15Krad irradiated group at Irish cobbler and weight loss was 16.5% in control, 5.1-5.6% in irradiated group, whereas rotting rate of Shimabara after 12 months storage was 100% in control, 15% in irradiated group and the weight loss of its was 12.6% in control, 7.3-7.4% in irradiated group. The moisture content in whole storage period of two varieties were 72-82% without remarkable changes. The total sugar and ascorbic acid contents were slightly decreased according to the dose increase and elapse of storage period, whereas reducing sugar content was increased. Irish cobbler was 90% markrtable after 9 months storage and 85% in Shimabara after 12 months storage. (Author)

[en] Two varieties of potatoes, Irish cobbler and Shimabara stored for seven and nine months respectively by irradiation combined with natural low temperature (year-round temperature change: 2-17degC) on a batch scale were investigated on the suitability for processing of potato chip. Nine months after storage, irradiated potatoes (Irish cobbler) tended to maintain somewhat better texture and sensory quality than untreated in potatoe chip processing. Peel rate, closely related to potato chip yield, of untreated potatoes were 20-25% higher than those of irradiated and Agtron color determination of potato chip from both irradiated were commercially acceptable. Preservation of potatoes by irradiation combined with natural low temperature was evaluated as an alternative method of the supply for raw materials of potato chip processing in the off-season in Korea.

[en] Published measurements of transport coefficients for Li⁺ ions in argon seem to be limited to the mobility and the longitudinal diffusion coefficient in the field-to-density ratio range at and below 200 Td^1-5. In this paper results are presented from measurements of the transverse diffusion coefficient to mobility ratio (Dsub(T)/μ) for Li⁺ ions in argon in the field-to-density ratio range 10 < E/n < 800 Td. The measurements were made with a drift tube mass spectrometer at a gas temperature of 295 +- 1 K using the modified Townsend method of Skullerud. The experimental curve is compared to a calculation by H.R. Skullerud in the same proceedings. (G.Q.)
