An oral drug delivery system using proteinoid microspheres is discussed with respect to itsunique dependence on pH. It has been found that certain drugs such as insulin and heparin canbe encapsulated in proteinoid spheres at stomach pH's (1--3). These spheres also dissemble atintestinal pH's (6--7) releasing the drug for absorption. Using this technique low molecularweight heparin and human growth hormone have been orally delivered successfully to severalanimal species. Future work has been proposed to study the interaction and binding of thespecific drugs with synthesized oligopeptides.

亚甲基二苯胺(mDA)被广泛用作生产聚氨酯和聚异氰脲酸酯的中间体.然而,当前mDA的生产工艺在控制(4,4’/(2,4’+2,2’))异构体比例方面还存在局限.其中,4,4’-mDA被认为是最有价值的异构体.尽管2,4'-mDA在市场上也有一定的需求,但如果能将其有效地转化为4,4'-mDA,将能显著提升其附加值.本文在使用苯胺的条件下,利用β分子筛等催化剂,通过双分子机制,可以选择性地将2,4'-mDA异构化为4,4'-mDA.尽管实验显示,多种酸性沸石具有较高的异构化活性,但mCm-68(具有mSE拓扑结构)的催化性能尤为出色,它不仅展现出高异构化活性,而且具有很好的选择性.mCm-68主要催化2,4'-mDA异构化为4,4'-mDA,而2,2'-mDA和低聚物的形成则可以忽略不计.本文还深入探讨了该择形作用的原因,并详细研究了酸位置在mSE分子筛孔道限制中的关键作用.

Recovery and grade prediction of pilot plant flotation column concentrate by a hybrid neural genetic algorithm

引用

International Journal of mining Science and Technology 2013年第1期23卷 69-77页

作者： F. Nakhaei m.R. mosavi A. sam Department of mining Engineering Shahid Bahonar Kerman University Kerman Iran Department of Electrical Engineering Iran University of Science and Technology Tehran Iran

Today flotation column has become an acceptable means of froth flotation for a fairly broad range of applications, in particular the cleaning of sulfides. Even after having been used for several years in mineral processing plants, the full potential of the flotation column process is still not fully exploited. There is no prediction of process performance for the complete use of available control capabilities. The on-line estimation of grade usually requires a significant amount of work in maintenance and calibration of on-stream analyzers, in order to maintain good accuracy and high availability. These difficulties and the high cost of investment and maintenance of these devices have encouraged the approach of prediction of metal grade and recovery. In this paper, a new approach has been proposed for metallurgical performance prediction in flotation columns using Artificial Neural Network (ANN). Despite of the wide range of applications and flexibility of NNs, there is still no general framework or procedure through which the appropriate network for a specific task can be designed. Design and structural optimization of NNs is still strongly dependent upon the designer's experience. To mitigate this problem, a new method for the auto-design of NNs was used, based on Genetic Algorithm (GA). The new proposed method was evaluated by a case study in pilot plant flotation column at Sarcheshmeh copper plant. The chemical reagents dosage, froth height, air, wash water flow rates, gas holdup, Cu grade in the rougher feed, flotation column feed, column tail and final concentrate streams were used to the simulation by GANN. In this work, multi-layer NNs with Back Propagation (BP) algorithm with 8-17-10-2 and 8- 13-6-2 arrangements have been applied to predict the Cu and mo grades and recoveries, respectively. The correlation coefficient (R) values for the testing sets for Cu and mo grades were 0.93, 0.94 and for their recoveries were 0.93, 0.92, respectively. The results disc

This study explains the multi-decadal shoreline changes along the coast of Kanyakumari from 1980 *** shorelines are extracted from the Landsat images to estimate the shoreline dynamics and future predictions using Digital Shoreline Analysis System(DSAS).By the estimation of End Point Rate(EPR)and Linear Regression Rate(LRR),it is quantified that the maximum erosion is 5.01 m/yr(EPR)and 6.13 m/yr(LRR)consistently with the maximum accretion of 3.77 m/yr(EPR)and 3.11 m/yr(LRR)along the entire coastal stretch of 77 *** future shoreline predicted using the Kalman filter forecasted that Inayam,Periyakattuthurai and Kodimunai are highly prone to erosion with a shift of 170 m,157 m and 145 m by 2030 and 194 m,182 m and 165 m by 2040 towards the ***,the western coast is highly prone to erosion and it is predicted that certain villages are prone to loss of economy and *** outcome of this study may guide the coastal researchers to understand the evolution and decisionmakers to evolve with alternative sustainable management plans in the future.

Characterization of energy and performance of swine fed a novel corn-soybean extruded product

Journal of Animal Science and Biotechnology 2015年第3期6卷 322-329页

作者： Katherine m Koch Robert C Thaler sam K Baidoo Crystal L Levesque Rebecca C Bott South Dakota State University University of minnesota Southern Research and Outreach Center

Background： A novel extruded product was characterized with a metabolism and lactation trial to establish the product＇s energy content, and its effects on lactating sow performance. The product was composed of a 60：40 corn-soybean blend, which was then extruded. This product containing the co-extruded 60：40 corn-soybean blend was commercially developed and is used extensively in swine diets in southwest minnesota. GE of dietary treatments were determined by isoperibol bomb calorimetry. Twelve barrows （59.9 ± 1.4 kg）, were used to determine the digestible and metabolizable energy of the extruded product. DE of treatments was determined by subtracting fecal energy from GE provided to barrows by each respective treatment. mE was determined by subtracting urinary energy from calculated digestible energy. Sixty-three sows were used for the lactation trial. Three dietary treatments were utilized： CONTROL （an industry standard diet）; PRODUCT （contained the product, vitamins and minerals）; OIL （matched the lysine：mE ratio of PRODUCT by addition of soy oil）. Sow weight, backfat thickness at the right and left last ribs, body condition score, number of piglets, and litter weights were recorded on the date of farrowing （d 0）, （d 9）, and at weaning. Blood and milk samples were obtained at weaning, and blood was analyzed for plasma urea nitrogen （PUN）, milk was analyzed for total protein and fat content. Results： On a dry-matter basis, the test diet provided 3,908 kcal/kg DE and 3,833 kcal/kg mE, which was significantly greater than the basal diet, which provided 3,633 kcal/kg DE and 3,567 kcal/kg mE （P 〈 0.0001）. These data were used to establish the DE and mE of the product, which were 3,882 kcal/kg and 3,798 kcal/kg, respectively, on an as-fed basis. No effect of diet was observed for changes in sow backfat （RBF P = 0.24; LBF P = 0.07） or body condition score （P = 0.12） during lactation. milk total protein （P = 0.69）, fat （P = 0.66）, PUN, average piglet gain （P = 0.55） and pi
