Sensory evaluation is the evaluation of signals that a buman receives via its sensory organs. Nowadays sensory evaluation is widely used in quality inspection and quality control of products. and many other fields. Actually sensory evaluation always give. uncertain and inprecise results, therefore it derivates many problems. we reviews in detail these problem and give some cumputing methods to resolve them.

Silicone coatings have been used in this study. The method adopted was the liquid drop analysis on the coated fabrics. The contact angle between a liquid drop and the fabric surface was measured with two liquids continuously and recorded by a computer. The surface energy was calculated by means of Owens *** measurement was adopted. The contact angle of liquids on the fabric coated silicone decreased with time was found. A compound solution DX has been found, so that the contact angle of the liquids on the fabric washed with DX becomes constant, and the surface energy of the fabric can be reduced to below 15 mJ/m2.

This paper systematically proposes basic requirements on normalization of comprehensive evaluation system with complex uncertain information due to human participation. Four basic academic ideas are as follows: 1) It is necessary to normalize conditions of information acquisition. 2) The effectiveness of comprehensive evaluation depends on the correctness of information acquisition. 3) Any evaluation results can be transformed into linguistic satisfactory degrees. 4) Linguistic values can include a great deal of information. This paper mainly deals with how to select objects to be evaluated, evaluators (panelists) and the methods of information processing, how to construct criteria of evaluation, how to normalize terms of evaluation, the results of evaluation, and the procedure of evaluation.

Cell culture assays are extensively used in drug discovery and development programs, biomedical research, and in many others areas of science. Currently,2D monolayer cellular assays serve as the gold standard. However, while they provide seemingly indispensable information on drug activity, it is estimated that of the putative drug candidates selected

It is widely accepted that in a turbulent boundary layer （TBL） with adverse pressure gradient （APG） an outer peak usually appears in the profile of streamwise Reynolds stress. However, the effect of APG on this outer peak is not clearly understood. In this paper, the effect of APG is analysed using the numerical and experimental results in the literature. Because the effect of upstream flow is inherent in the TBL, we first analyse this effect in TBLs with zero pressure gradient on flat plates. Under the individual effect of upstream flow, an outer peak already appears in the profile of streamwise Reynolds stress when the TBL continues developing in the streamwise direction. The APG accelerates the appearance of the outer peak, instead of being a trigger.

Pandé is a Congolese fermented food produced from fruit pulps of raffia palm. The aim of this study was to explore the diversities in bacterial communities in the unfermented pulps (control) (PNFL) and fermented pulps obtained from fruits using boiling (PMF) and purchased at markets in Brazzaville (PFL) and using Illumina MiSeqsup>TMsup> sequencing of 16S rRNA gene. A total number of 157,054 sequences was obtained and grouped into 737 operational taxonomic units (OTUs). These were classified into 13 phyla, 26 classes, 48 orders, 96 families and 176 genera. At the phylum level, the most frequent bacterial communities were: for PFM, Proteobacteria (38.94%) and Firmicutes (19.37%);for PFL, Firmicutes (69.10%) and Proteobacteria (30.89%);for PNFL, Firmicutes (84.92%) and Proteobacteria (14.22%). were the most frequent in PFL, while Acidobacteria (40.02%), Proteobacteria (38.94%) and Firmicutes (19.37%) were preponderant in PFM. Firmicutes (84.92%) and Proteobacteria (14.22%) were the most common in unfermented pulps (PNFL). Lactobacillus (47.70%) and Gluconobacter genera (15.33%) were the most represented in the PFL sample. Acidipila (35.56%) and Rhizomicrobium (11.41%) were preponderant genera in the PFM sample. Weissella genus was the most frequent in the PNFL sample. Hierarchical cluster indicated that the samples could be grouped into two groups of different origins. PCA showed that main genera were higher in the fermented samples. The diversity was higher in the fermented pulps or Pandé than in the unfermented pulps. Pandé can be a potential source for the isolation of bacteria with biotechnological potential.
