In a competitive business environment, the textile industrialists intend to propose diversified products according to consumers
preference. For this purpose, the integration of sensory attributes in the process parameters choice seems to be a useful
alternative. This paper provides fuzzy and neural models for the prediction of sensory properties from production parameters
of knitted fabrics. The prediction accuracy of these models was evaluated using both the root mean square error (RMSE) and
mean relative percent error (MRPE). The results revealed the models ability to predict tactile sensory attributes based on
the production parameters. The comparison of the prediction performances showed that the neural models are slightly powerful
than the fuzzy models. 相似文献

Sinarundinaria alpina is a species of mountain bamboo which is a source of various conflicts between the managers of the Kahuzi-Biega National Park (KBNP) and surrounding communities. This mountainous species is threatened by these communities to meet their need for various uses. Six permanent plots of 3 hectares were set between 2000–3000 metres above sea level and floristic inventories were made. In addition, information related to anthropogenic threats related to bamboo exploitation was recorded. All data were analysed using quantitative statistical parameters. Results suggest the existence of 196 species in these six permanent plots of the group Bamboo. The position of this Sinarundinaria alpina vegetation in the dynamic rainforest recovery dynamics is confirmed by the presence of trees and tree-nurseries of these trees. Fifty-three species, 27% of the plants observed, including Sinarundinaria alpina seedlings, contribute to the daily feeding of great apes, mainly Grauer’s Gorilla (Gorilla beringei graueri). This forest appears to be one of their critical habitats. The decrease in the area covered by bamboos is due primarily to anthropogenic activities but also some natural hazards (expansion of Sericostachys scandens, natural fading of Bamboo and attacks by beetles). Following these findings, conservation strategies were proposed. Several strengths were noted, including multiplication of bamboo nurseries and distribution of seedlings to local communities. This can be seen as a strong development of this sector in the future. This study is a preliminary assessment for further investigation. 相似文献

Electrodiffusion diagnostics are widely used for measurement of local wall shear stresses in liquid flows. At present, this
method requires special electrolytes, so the applications are limited to laboratory conditions. Another problem concerns the
dependence of the limiting diffusion current on the electrode surface state and on the bulk concentration of the electroactive
species. In this paper, it is shown that the delay time between generation of the electroactive species and their detection
on the downstream electrode, is directly related to the local wall shear stress value. Thus, the measurements of the delay-time
open a new way for the study of near-wall hydrodynamics. This new method has been confirmed experimentally using an electrolyte
containing the conventional hexacyanoferrate(III/II) redox couple, as well as with the chlorine (chloric(I))/chloride couple
in an electrolyte similar to seawater. 相似文献

A spatial hydroeconomic model was developed to analyze the competition between small private (SPIS) and large public (LPIS) irrigation systems for water control in tropical watersheds and applied to several water allocation policies in Kou watershed in Burkina Faso. Capital (cash and motorpumps) is the main constraining factor for SPIS expansion, and capital inflow accelerates SPIS development and reduces water flows for downstream LPIS users. As SPIS is more cost-effective and less water thirsty, LPIS needs to shift to less water-demanding and high-value crops or adopt more water-saving practices. Otherwise, only a sharp rice yield increase in LPIS can justify a reserved water quota for downstream users. 相似文献

Induced stresses in textiles play a major role in their mechanical properties, either during fabrication or use. The aim of this work is to present the development of a dedicated sensor, which could be directly inserted in a fabric. The study is focused on seat-cover fabrics. The developed sensor is based on polyvinylidene fluoride films, which can easily be integrated in multilayer textiles used for seat upholstery. The metrology method used is the study of phase variations of the sensor under different loads. Results have shown that these variations are linear, and differ with “complex” fabric type. A correlation study between Kawabata compression parameters and phase variations didn't show any relationship between slope values and compression properties when the surface fabrics of “complex” are compared, but a classification in “families” is possible when different foams are considered. Future studies using this technique should demonstrate if these “smart” textiles could find applications in automotive field. 相似文献

In this article, we have studied the possibility of using carbon-based screen-printed probes for electrochemical flow and mass flux measurements. Such probes have, up to now, been mainly used as biosensors to study in vivo reactions. Our study shows that screen-printed sensors allow the measurement of mass flux and mean wallp shear stress with good accuracy and high reproducibility. The existence of a micro-porous layer covering the surface of screen-printed electrodes has been revealed by means of the impedance measurements and has been confirmed by Scanning Electron Microscopy. This layer influences the statistical characteristics of the turbulent limiting diffusion current and should be taken into account as an additional transfer function between the current and the velocity fluctuations. The use of screen-printed sensors opens new possibilities in the field of electrochemical flow diagnostics. The advantage of this new manufacturing technology lies in the possibility of serial mass production at very competitive prices (disposable sensors) combined with the possibility of the manufacture of segmented electrodes or matrix of electrodes. These new possibilities can be used for various industrial applications as well as for scientific studies on near-wall turbulent mass transfer. Furthermore, it is possible to envisage the development of a hybrid sensor (electrodiffusional/biochemical) allowing the study of in situ biochemical reactions in a flow. 相似文献

During the week of October 15-24, 1995 a team of 65 medical, anaesthesiology, surgical, nursing and paramedical personnel travelled to Guatemala City, Guatemala to perform cardiac surgery on children with complex congenital and acquired valvular heart disease. During this mission 42 patients had their lesions surgically repaired. Cardiopulmonary bypass was required in 36 cases. There were no anaesthetic or surgical deaths. All six patients who did not require cardiopulmonary bypass were extubated in the operating room. Of the patients who required cardiopulmonary bypass, 23 were extubated in the operating room (64%). There was no intraoperative anaesthetic morbidity nor postoperative respiratory complications. No patients was reintubated after planned extubation. Cardiac surgery in paediatric age patients can safely be performed in developing countries if close attention is paid to proper patient selection and one maintains the standards of care practised in developed countries. 相似文献

BACKGROUND: Today, few known plant species provide both an essential oil (EO) and a vegetable oil (VO). Seed and husk of two Aframomum species were investigated and compared in terms of EO, fatty acids, tocopherols, and tocotrienols. RESULTS: EO yield reaches 15.3 g kg−1 in the seeds and 3.2 g kg−1 in the husks, while VO yield is 180.0 g kg−1 in the seeds and 25.0 g kg−1 in the husks. β‐Pinene, 1,8‐cineol, α‐selinene, terpine‐4‐ol, linalool, myrtenal and β‐caryophyllene are the major compounds of seed and husk EO. Fatty acid analysis of two Aframomum species shows that oleic, linoleic, and palmitic acids were the major compounds of VO. Total sterol contents reached 4.3 g kg−1 in seed VO and 8.5 g kg−1 in husk VO. An appreciable amount of tocopherols (0.52 g kg−1) was found in seed VO. CONCLUSION: The seed and husk oil of A. stipulatum and A. giganteum fruits are rich sources of many bioactive constituents such as fatty acids, sterols, tocopherols and tocotrienols. These tropical wild fruits can be considered as new Aroma Tincto Oleo Crops (ATOC) resources that contain both EOs and VOs. Copyright © 2012 Society of Chemical Industry 相似文献
