Objectives: The aim of this research was to optimize the parameters for the vacuum impregnation of aloe vera into dried yacon (Smallanthus sonchifolius Poepp. & Endl.) flakes. Methodology: A surface response methodology was use to evaluate the product optimization. Matrix engineering, using a vacuum impregnation technique, was employed to incorporate components with physiological activity into the pores present in the yacon flakes. An orange pulp yacon was used as the starting material and Aloe Gold Seal-Natural 200X (AGS) was used for the impregnate solution. A solution of 15 g/100 ml Natural aloe 200X Gold Seal-yacon was used to impregnate yacon samples measuring 40 mm in diameter and 5 mm thick. The results show an average impregnation of 0.0721 m3 of solution/ m3 fresh fruit and an effective porosity of 18.97%; the amount of aloe vera incorporated in the food matrix was between 22.5 and 54.6 mg/100g sample. Optimized parameters were identified as 451.777 mbar and 22.0711 minutes. Results: From the results, it is concluded that yacon is an excellent raw material for vacuum impregnation of  aloe vera.

Abstract Background Many traditional Chinese medicine compositions can moisturize the skin and utilize in cosmetics. Using a combination of Chinese Medicine Materials and guided by Traditional Chinese Medicine principles, this study selected Echinacea purpurea to protect the skin barrier, Dendrobium nobile to clear heat and promote fluid production, Sophora flavescens to clear heat for diminished inflammation, and Aloe vera combined Lycium barbarum to nourish yin, to together form a "poly TCM moisturizing formulation". Methods These poly plant extracts were investigated and optimized for the stability, safety and moisturizing ability. The combination moisturizing effect was determined by measuring the expression of FLG mRNA, CLDN-1 mRNA and AQP3 protein. Toxicological analysis included a red blood cell hemolysis test and a 3T3 phototoxicity test . Results It has been observed that by using polysaccharide yield as the evaluation criterion showed optimal extraction at a material-to-liquid ratio of 1:100, an extraction temperature of 100 °C, and an extraction time of 3 h. Moisturizing effect experiments showed that the expression of FLG mRNA, CLDN-1 mRNA and AQP3 protein was significantly increased. Toxicological tests showed that the composition was safe and caused no irritating effects. Conclusion Based on these results, this poly TCM moisturizing formulation is safe within moisturizing effects and can be used as a moisturizing raw material in cosmetics.

Initial Process

The application of vacuum osmotic impregnation at constant temperature (25 °C) to obtain high moisture minimally processed papaya was evaluated. The fruit effective porosity was determined employing vacuum impregnation in isotonic sucrose solutions, obtaining values of around 3.4%. The fruit was submitted to vacuum osmotic dehydration (VOD) processes (60 mbar) in 60 °Brix sucrose syrups to depress a w from 0.99 to 0.98 (or less), always having a greater effectiveness than in the case of osmotic dehydration (OD) processes at atmospheric pressure. The use of a VOD initial process for different times, followed by the application of OD (called pulsed vacuum osmotic dehydration, PVOD, processes) had a greater effectiveness in depressing the aw than when only OD was applied in pro cesses up to 240 min. The pH reduction due to the addition of citric acid (2.5, 5.0 and 7.5%) to the sucrose syrup was more effective when applying VOD or PVOD processes. Minimally processed papaya ( aw 0.98, pH 3.5) could be obtained by applying VOD for only 10 min if the sucrose syrup had a citric acid concentration of 7.5%, or PVOD processes (VOD < 15 min and then OD < 45 min), em ploying concentrations of 2.5 and 5.0% of acid in the syrup.

This paper presents a study investigating the effect of differing textile substrates on the performance of multilayer, aqueous fabric supercapacitors. Three widely available textiles, cotton, polyester-cotton and silk were chosen, and all underwent the same activated carbon deposition process to form electrodes. An automated spray coating was implemented to precisely control the loading of the carbon, and to enable a uniform coating. A vacuum impregnation technique was utilized to increase the wettability of the electrodes and improve the absorption of the aqueous electrolyte. The multilayer supercapacitors showed excellent electrochemical and mechanical stability, with the choice of textile substrate found to have a profound effect on the performance. The silk-based supercapacitor was found to have a gravimetric capacitance of 20.2 F.g−1 (56.6 mF.cm−2) at a carbon loading ratio of 15.7 %wt. The polyester-cotton supercapacitor, however, was found to have a superior areal capacitance of 118 mF.cm−2 at a carbon loading ratio of 14.1 %wt. This work will be used to select future substrates and carbon loading levels for real-world e-textiles.

Several local mining sites of sand and gravel have been operating for decades in the Rapti River. River gravels are consumed in Hetauda, Narayanghad and areas in India near the border between Nepal and India. Until now little known about consumers concerning about quality of gravel. The present study was carried out to evaluate quality of river gravel to know its suitability for aggregate (raw material for concrete and road). The samples of river gravel were analysed for petrographic, physical, mechanical and chemical properties. Samples were categorised as quartzite group, carbonate group and granite group according to British Standard Institution (BSI). Among these, samples of quartzite group were found dominant. Image analysis of gravel showed that clasts were well graded. The majority of the samples had rounded, high sphericity and oblate triaxial clasts. The surface texture of clasts was rough to smooth. In terms of shape, workability of gravel was satisfactory. Gravel samples possessed low water absorption value (0.69 to 1.12%) and low effective porosity. Dry density of samples ranged from 2460 to 2680 kg/m3. Aggregate impact values of samples (14.2 to 16.1%) showed good soundness. Los Angeles abrasion test also showed consistent hardness of each of the samples as uniformity factor did not exceed 0.2. Magnesium sulphate values ranged between 4.46% and 7.29% suggesting good resistance against chemical weathering and frosting. Comparing with the existing Nepal Standard, British Standard and American Standard of Testing Material, the studied samples were suitable for concrete and road aggregates.   doi: 10.3126/bdg.v10i0.1425      Bulletin of the Department of Geology, Tribhuvan University, Kathmandu, Nepal, Vol. 10, 2007, pp. 99-106
