Jun YIN, Baojun JIANG, Xiaoyan WU, Liang LIANG, Xue LIU
Journal of Water Resource and Protection (JWARP) , 2009, DOI: 10.4236/jwarp.2009.14034
Abstract: In order to study the effect of saw powder on leachate production, degradation of rubbish, COD and NH3-N concentration of leachate, three cylinder reactors for anaerobic landfill disposal were built to simulate the op-eration of landfill. In this experiment, leachate quantity, settling height of rubbish layer, COD and NH3-N concentration were monitored. The results come from experiment data analyses indicate that saw powder has strong effect on reducing leachate quantity and accelerating degradation of rubbish. In 60 days, saw powder mixed in rubbish layer can reduce 1200-1300mL leachate every liter rubbish, moreover, rubbish layer with saw powder mixed in settled more leachate than rubbish layer with no saw powder mixed in for 5cm. The ex-perimental results indicate that saw powder can reduce COD concentration of leachate and adsorb NH3-N, too.

Foods , 2013, DOI: 10.3390/foods2020198
Abstract: The objectives of this study were to develop soy milk with improved food quality and to enhance the functional attributes by incorporating short-time germination into the processing. Changes in trypsin inhibitor activity (TIA), phytic acid content and total phenolic content (TPC) in soy milk produced from soybeans germinated within 72 h were investigated to determine the optimum germination condition. Results from the present research showed significant ( p < 0.05) improvement of TPC in cooked germinated soybean milk, while both the TIA and phytic acid content were decreased significantly ( p < 0.05). In the subsequent evaluation on the quality attributes under the optimum germination condition, soy milk made from 28 h-germinated soybeans presented enhanced nutritional value and comparable physicochemical properties to conventional soy milk. The current approach provides a feasible and convenient way for soy-based product innovation in both household and industrial settings.

Mathematics , 2013,
Abstract: A subgroup $H$ of a group $G$ is called weakly s-supplemented in $G$ if there is a subgroup $T$ such that $G=HT$ and $H\cap T\le H_{sG}$, where $H_{sG}$ is the subgroup of $H$ generated by all those subgroups of $H$ which are s-permutable in $G$. The influence of primary weakly s-supplemented subgroups on the structure of finite groups is investigated. An open question promoted by Skiba is studied and some known results are generalized.

Physiological Regulation of Valve-Opening Degree Enables Mussels Mytilus edulis to Overcome Starvation Periods by Reducing the Oxygen Uptake  [PDF]
Baojun Tang, Hans Ulrik Riisg?rd
Open Journal of Marine Science (OJMS) , 2016, DOI: 10.4236/ojms.2016.63029
Abstract: During periods of starvation, the blue mussel Mytilus edulis reduces its valve gape and thus the filtration rate whereby the oxygen uptake becomes reduced. Considering the frequency with which M. edulis in the field experience shorter or longer periods with low phytoplankton concentrations it is of great importance to understand the bioenergetic implications the valve opening-closing mechanism. Here, we tested the hypothesis that M. edulis during starvation regulates the opening degree of its valves in such a way that the oxygen concentration in the mantle cavity is reduced in order to minimize the respiration and at the same time prevent anaerobic metabolism which is energetically expensive. This was experimentally done by measuring the oxygen-concentration changes in the mantle cavity of both starved and fed mussels using a fibre-optic oxygen meter with a small sensor inserted into the mantle cavity through a hole drilled in the valve. It was observed that when there were no algal cells in the ambient water, the mussels gradually closed their valves resulting in a decline of the filtration rate along with a simultaneous decrease in the oxygen concentration in the mantle cavity and subsequently a remarkable decrease in the respiration rate. Typically, a starved M. edulisclosed its valves for a certain period of time followed by a short period when it re-opened and this resulted in an alternating fall and rise of the oxygen concentration in the mantle cavity. Therefore, the low oxygen consumption rate of M. edulis in phytoplankton depleted water can be interpreted as an efficient physiologically regulated mechanism that allows the mussel to save energy during a starvation period.
Chaotic system for the detection of periodic signals under the background of strong noise
Yue Li,Baojun Yang
Chinese Science Bulletin , 2003, DOI: 10.1007/BF03183261
Abstract: We propose a method to study the chaotic system for the detection of periodic signals in the presence of strong background noise. The numerical experiments indicate that the chaotic system constructed from the modified Duffing-Holmes equation is sensitive to the weak periodic signal mixed with noise, and it has certain immunity to noise. The signal to noise ratio for the system can reach to about-91 dB.

Multi-destination release of nanoparticles using an optical nanofiber assisted by a barrier
Hongbao Xin,Baojun Li
AIP Advances , 2012, DOI: 10.1063/1.3694933
Abstract: This work provides optical delivery and controllable multi-destination release of nanoparticles (NPs) using a defect-decorated optical nanofiber (NF) assisted by a barrier. The delivery and release was accurately controlled using different evanescent optical fields at different regions of the NF by changing the injected optical power. The NPs (polystyrene, 713 nm diameter) were delivered along the NF (690 nm diameter) toward the decorated defect when a laser beam at a wavelength of 980 nm was injected into the NF. At an injected optical power of 25 mW, the NPs were delivered at an average velocity of 2.9 μm/s and 90% of them were released around the barrier, which is set beside the defect. When the power was increased to 40 mW, the average delivery velocity reached 4.2 μm/s and 92% of the NPs were released at the side of the defect opposite to the barrier. By further increasing the power to 80 mW, the average delivery velocity further increased to 8.2 μm/s. Consequently, 90% of the NPs moved across the defect and were delivered to the next destination at an average velocity of 5.2 μm/s. The experimental results were then explained theoretically using numerical simulations.

Diffusion Profiles of Health Beneficial Components from Goji Berry (Lyceum barbarum) Marinated in Alcohol and Their Antioxidant Capacities as Affected by Alcohol Concentration and Steeping Time
Yang Song,Baojun Xu
Foods , 2013, DOI: 10.3390/foods2010032
Abstract: The fruit (goji berry) of Lycium barbarum, a traditional Chinese medicine, has been widely used in health diets due to its potential role in the prevention of chronic diseases. One of the most popular applications of goji berry is to make goji wine in China by steeping goji berry in grain liquor. However, how the steeping process affects antioxidant capacities and phytochemicals of goji berry is not yet fully understood. Therefore, to provide scientific data for the utilization of goji berry in the nutraceutical industry, the diffusion rate of betaine, β-carotene, phenolic compounds in goji berry and their antioxidant capacities affected by alcohol concentration and steeping time were determined by UV-Visible spectrophotometer. The results showed that low alcohol concentration (15% or 25%) would promote the diffusion of betaine and increase antioxidant activity, while high concentration (55% or 65%) would generally increase the diffusion of flavonoids and reduce antioxidant activity. The steeping time had no significant effect on the diffusion of phenolic compounds and antioxidant activities. However, all goji berry wine steeped for 14 days with different alcohol concentrations exhibited the highest betaine concentration. Current findings provide useful information for the nutraceutical industries to choose proper steeping time and alcohol concentration to yield desired health promotion components from goji.
