The experiment indicates that the satisfactory fermentation results(ethanol concentration is 16.12%,survival reducing sugar is 0.22%,survival total sugar is 1.26%,starch reality ethanol productivity is 52.29%,and starch utilization ratio is 92.08%) can be achieved when the ratio of corn powder and water is 1∶1.21 and the fermentation time is 50.5h.

The optimal sorption conditions for discarded brewers yeast were as follows: pH 4.0,Cu2+ concentration 100 mg·L-1,yeast recruitment 1.0 g·L-1,sorption temperature 25 ℃,sorption time 2.5 hours.

The results suggested that the optimal technical conditions were as follows : 80 % aqueous ethanol solution as extracting reagent, proportion of materials and extracting reagent was 1∶5, temperature at 80 ℃, 1.5 h extraction time, and the yield was 2.2 %.

The total biogenic amine content was increased from 268.7±0.32 mg·kg-1 to 347.7±24.31 mg·kg-1 during the fermentation time from 12 to 18 h, but it remained almost the same from 18 to 24 h.

The proof is based on a variant of Moser's method using time-dependent vector fields.

We present two-sided singular value estimates for a class of convolution-product operators related to time-frequency localization.

The Balian-Low theorem (BLT) is a key result in time-frequency analysis, originally stated by Balian and, independently, by Low, as: If a Gabor system $\{e^{2\pi imbt} \, g(t-na)\}_{m,n \in \mbox{\bf Z}}$

Gabor Time-Frequency Lattices and the Wexler-Raz Identity

Gabor time-frequency lattices are sets of functions of the form $g_{m \alpha , n \beta} (t) =e^{-2 \pi i \alpha m t}g(t-n \beta)$ generated from a given function $g(t)$ by discrete translations in time and frequency.

This paper discusses the statements of Mr. Peirce of America and of Mr. Leaf and Mr. Glaskin of England and of Prof. Daredobech of U.S.S.R., concerning the forms of loops, their lengths and the coefficients of density ratio of plain knitted fabric. An experiment undertaken reveals that the lengths of loops derived from their formulae are not far from the actual values, therefore they are of certain practical use. Upon experiment, it is found, however, that the coefficients of density ratio of plain knitted fabric...

This paper discusses the statements of Mr. Peirce of America and of Mr. Leaf and Mr. Glaskin of England and of Prof. Daredobech of U.S.S.R., concerning the forms of loops, their lengths and the coefficients of density ratio of plain knitted fabric. An experiment undertaken reveals that the lengths of loops derived from their formulae are not far from the actual values, therefore they are of certain practical use. Upon experiment, it is found, however, that the coefficients of density ratio of plain knitted fabric do not correspond with what have been stated by Mr. Leaf and Mr. Glaskin, because the values of coefficients derived from their formulas sometimes become imaginary; and at the same time they do not appear to be the value of 0.8 as work out by Prof. Daredobech. Therefore the theoretical coefficients derived by these workers differ from what are obtained from our experiment. The actual coefficients of density ratio of plain knitted fabric still have to be derived.

This paper aims at a discussion on problems of labor organization of weavers in accordance with an article written by Soviet author E. A. Sterin issued on "Textile Industries of U.S.S.R." No. 1, 1956. Certain data acquired through a detailed time-study before and after the rearrangement of labor organization are included with analytical comments. The main part of this paper deals with the following problems: 1. Analysis and evaluation of data acquired from the time-study regarding the utilization of working hours and the factors affecting the workers' efficiency; 2. Theoretical survey on the changes in production rates of looms in the light of a comparison with actual production situation; 3. Discussions on improving quality of products, effective management in work lots, harmonious operations during a shift, better utilizing of working hours, etc.; 4. Suggestions.

In the degumming of the ramie the chemical process, usually employed in this country is to boil the material in the alkaline solution. While the experiments in this paper prove that the time required for boiling the material in the alkaline solution may be reduced by the following procedures: After softening and wetting, the material is treated in the chlorine for 5-8 minutes, and then boiled in the alkaline solution for about 3 hours.

In the degumming of the ramie the chemical process, usually employed in this country is to boil the material in the alkaline solution. While the experiments in this paper prove that the time required for boiling the material in the alkaline solution may be reduced by the following procedures: After softening and wetting, the material is treated in the chlorine for 5-8 minutes, and then boiled in the alkaline solution for about 3 hours. The same favourable results are obtained by introducing the bleaching solution instead of chlorine for the experiments in mills. As for the physical properties of the fiber, the result of the experiment shows that the fiber strength is 57,98 gr. for the materials treated by chlorine, and that 52,76 gr. for thosenot treated by chlorine. Hence it is proved that there is no effect on the fiber strength for those materials under the process suggested in this paper.
