Based on the silk fabric specifications database, the paper proposes two technological parameters of selvage tightness coefficient and selvage warp density coefficient, and realizes the quantitative relationship of corresponding parameters between selvage and fabric. By making use of thousands data of silk products in the silk fabric specifications database, corresponding programs are wrote to achieve the automated numeration of various selvage parameters .Then the paper discusses three typical silk fabrics which contains eleven subclasses and analyses the distribution of the two parameters, with the comparison of selvage parameters in sub-categories of the same categories. The conclusion can provide a theoretical basis for the silk fabric design and production.

The main shortages of traditional design for silk garment are: stylized design concept; simple and plane model; lack of diversified skin texture; and the color limit to the inherent quality of silk fabric, not fit for diversified and personalized aesthetic need of modern people. This paper breaks through traditional fabric design, and proposes optimization design methods of modern silk garment. The methods include matching different silk fabrics with different textures, or matching silk fabrics with other fabrics such as leather, fur, jean and knits.

With the development of science and technology, silk fabric becomes more and more colorful. On the one hand, hand-painted silk fabrics have unparalleled appearance reflecting the designer’s concept, on the other hand high fashion is one of high value-added products. High fashion design needs more unique fabric and the hand-painted silk fabric is just the right choice. In the West, designers attach more importance to developing silk fabric in high fashion design extensively and innovatively; while in China the high fashion design is still holding a backward position. Through studying the relationship of hand-painted silk fabric and high fashion in China, we can forecast the trend of hand-painted silk in high fashion design effectively, and at the same time promote the development of high fashion design.

This report describes an unusual and persistent dysphonia in two young women who had taken a therapeutic regimen of isotretinoin for intractable acne. We report perceptual and instrumental data for their dysphonia, and pose a theoretical basis for the relationship of dysphonia to this drug. We also provide recommendations for reducing the risk of acquiring a dysphonia during the course of treatment with isotretinoin.

Two lichens species (ParmotremapraesorediosumandHeterodermialeucomelos)were assessed for dye production using boiling water method (BWM) and ammonia fermentation method (AFM). The dyes were applied on silk fabric. Three types of mordant were used i.e. alum, iron and vinegar through meta-chrome (simultaneous) method of natural dyeing. The K/S values, colour coordinates values and colour differences (ΔE) of the dyed samples were measured. Dyeing fastness properties of the dyed silk fabrics were assessed for washing, rubbing and light. TheP.praesorediosumextracts yielded beige to dull brown shades using BWM and pinkish-purple using AFM, whereas theH.leucomelosextracts produced yellowish-brown shades for both BWM and AFM on the silk substrate. Modanting seemed to be effective in increasing the K/S values of all mordanted fabrics except in the case of silk fabric dyed withP.praesorediosumextracted from AFM. Fastness ratings to washing and rubbing were all very good (5-4) for bothP.praesorediosumandH.leucomelosdyed silk fabrics. The fabrics dyed withP.praesorediosumandH.leucomelosextracts produced strong and deep colours as their ΔE values were higher and increased obviously of all mordanted fabrics. It can be concluded thatP.praesorediosumandH.leucomelosextracted from BWM and AFM methods can be used as an alternative dye source.

AbstractThe process of resource utilization by Dendroctonus frontalis Zimmerman attacking loblolly pine, Pinus taeda L., was investigated. The quantitative relationship of attacking parent adult D. frontalis as a function of the normalized infested bole height is described by the model y = Ax(1−x)eBx. Greatest attack density occurs at the mid-bole of the tree and tapers toward the top and bottom. Gallery length (and hence eggs)/100 cm2 was independent of attack density. The relationship between gallery length (or eggs) per parent adult and parent adult density is described by the exponential decay curve y = AeBx, indicating that gallery length and egg population density are controlled by a density dependent compensatory feedback process operating instantaneously. Further support for the mechanism was obtained by analyzing the gallery length per parent adult at different locations on the infested bole. The relationship is described by the model y = [AeBx]/[x(1−x)] and indicates that gallery construction and egg population per attacking beetle increase in the upper and basal portion of the bole. The result is a uniform amount of food and space per individual of the developing population.

In previous work, we estimated a dynamic model of the Italian economy, showing that its weakness in the past two decades is mainly due to the slowdown in total factor productivity growth. In those models, two parameters play a key role: technological progress and the elasticity of substitution. Recent estimates of those parameters are affected, in our opinion, by a specification problem: technological parameters are inherently long-run but their estimates are based on short-run data. Looking deeply into the estimation procedure, we show that the misspecification issue present in the estimates gives rise to a spurious regression bias (high R2, low DW), because the standard approach does not incorporate frictions and rigidities. Our modeling strategy takes account of them. Although we cannot in general say that our framework gets rid of the serial correlation problem, the statistics for our model do show that residuals are not serially correlated.
