Opis:
Sapindus saponins are potential biosurfactants that can widely be used to replace many chemical cleaning products. This study aimed to investigate the water extraction of saponins from the pericarps of Sapindus mukorossi and enhance the sensory properties of the extract by yeast fermentation. Extraction conditions including temperature, solid-to-liquid ratio, extraction time, and number of extraction times were studied. A yield of 21.4% was obtained by 2 h of extraction at 80 °C with a solid-to-liquid of 1/6 (w/v) and two times. Fermentation was used to purify the Sapindus extract, inoculum amount and fermentation time were optimized. The fermentation by S. cerevisiae (2%) within 4 days significantly improved the color and smell of aqueous extract, turbidity decreased by 75.6%, total sugar content decreased by nearly 50% and saponins content slightly decreased. These results could contribute to the development of industrial–scale production of Sapindus saponins.

Opis:
Ngoc Luong thermal mineral water at Vo Am ecotoursim, Ngoc Luong commnune, Yen Thuy district, Hoa Binh province, northern Vietnam. The thermal mineral water source is at karstic-fractured limstones of Dong Giao Formation aged Anisi. Methods used in this study conists of basic field survey of hydrogeology, resistivity, borehole drilling, pumping tests, and thermal mineral water sample analysis. The thermal mineral water is classified as radon-radium, low mineralised thermal mineral water. The water source is originally related to the deep Moc Chau-Tam Diep Fault directing northwest-southeastward. Its exploration reserve is estimated at 1,497 m3/d with good quality, sastifying all national criterals for the use of domestic supply, bathing, and medical treatment. This is one of ten rare thermal-mineral water sources in Vietnam, containing radon and radium. It is thefore necessary to have good management to ensure the thermal-mineral water to be effectively exploited, used, and protected.

Opis:
Oil and gas projects differ from regular investment projects in that they are frequently large-scale, categorised as vital national projects, highly technological, and associated with significant risks. Drilling rigs are a crucial component of the oil and gas sector and the majority of the systems and equipment aboard drilling rigs are operated automatically. Consequently, it is crucial to address the topic of an advanced control theory for off-shore systems. Network technology connected to control is progressively being used to replace outdated technologies, together with other contemporary technologies. In this study, we examine how to adapt a networked control jacking system to the effects of internal and external disturbances with a time delay, using a Fuzzy controller (FC)-based particle swarm optimisation. To demonstrate the benefit of the proposed approach, the developed Fuzzy Particle Swarm Optimisation (FPSO) controller is compared with the fuzzy controller. Finally, the results from simulations and experiments utilising Matlab software and embedded systems demonstrate the suitability of the proposed approach.

Opis:
Essential oil extraction technique from mandarin pixie peels by hydro-distillation is optimized by respon-se surface methodology (RSM). Mathematical techniques were used in experimental design to evaluate the impacts of factors that affect the extraction process and improve the yield of the extraction process. A central mixed design based on infl uencing variables such as water ratio (3–5 mL/g), temperature (110–130° C) and extraction time (90–150 min) was adopted with essential oil yield as the target func-tion. Correlation analysis of the mathematical regression model showed that the quadratic polynomial model can be used to optimize hydro-distillation of pixie mandarin oil. The results showed that under the optimum extraction conditions, the highest quantity of essential oils was achieved (7.28 mL/100 g materials). In terms of statistical analysis, the signifi cance levels (p-value <0.05) of the model showed that the experimental results had a good impact between factors. The coeffi cient of determination indicating the match between the experimental value and the predicted value of the model was high (R2>0.9). The chemical composition of the essential oil was analyzed by Gas Chromatography-Mass Spectrometry, revealing the dominance of limonene content (97.667%), which implies that the essential oil of pixie mandarin could be an alternative source of limonene.

Opis:
The inverse dynamics method is applied to the investigation of dynamical behavior of a parallel manipulator. The substructure technique is used for creating a differential-algebraic system of equations that describes motion of the Stewart-Gough platform. The system of equations is modified into a set of linear differential equations for the determination of the solution of the inverse dynamics problem. A computational algorithm is developed to solve the inverse dynamics of the manipulator. Several trajectories of the moving platform are simulated as a result of the inverse dynamics problem of the Stewart-Gough platform according to the substructure technique.
