An experimental investigation was conducted on the laminar flow frictional characteristics of suspensions with microencapsulated phase change material (MEPCM) in water flowing through rectangular copper minichannels. The MEPCM was provided at an average particle size of 4.97 μm, and was mixed with distilled water to form suspen- sions with various mass concentrations ranging from 0 to 20%. The experiment was per- formed to explore the effect of MEPCM mass concentration on friction factor and pressure drop in the minichannels. The Reynolds number ranged from 200 to 2000 to provide laminar and transitional flows. It was found that the experimental data for the suspensions with 0 and 5% concentration agree well with the existing theoretical data for an incom- pressible, fully developed, laminar Newtonian flow. For the suspensions with mass con- centrations higher than 10%, there is an obvious increase in friction factor and pressure drop in comparison with laminar Newtonian flow.

Hepatocytes were isolated from suckling porcine using modified seglen’s collagenase perfusion technique, and were encapsulated with alginate-polylysine-alginate (APA) microcapsules. Fulminant hepatic failure(FHF) was induced in male SD rats by galactosamine. Hemoperfusion performed 24hErs after galactosamine injection. In vitro culture, both encapsulated hepatocytes and free hepatocytes express the ability to synthesis Albumin, Urea .for 7 days, Encapsulated hepatocytesperfusied with Williams’ E medium was shown to provide albumin, urea synthesis functions in 24hrs. The survival time after treatment of microencapsulated hepatocytes hemoperfusion group was longer than othergroups, and Serum ALT, TBIL levels decreased.

Background: Iron deficiency anemia (IDA) in children and infants is a common nutritional problem all over the world. Infants and young children have a high risk for developing iron deficiency (ID) because they have high demand for iron during the period of rapid growth. This is aggravated by the insufficiency of iron in their diet. Iron supplementation programs using pediatric tablets or drops have not been successful in the control of anemia amongst infants and children in some countries. “Sprinkles” is an innovative multi-micronutrient home fortification strategy to control iron deficiency and anemia to be more useful. Objective: The objective was to estimate the prevalence ID and IDA in infants and children in Ibb City, Yemen Republic;evaluate the use of a new form of iron and determine the hematologic response to different doses and forms of iron in Sprinkles and iron drops. Design: Using a prospective, randomized, controlled design, we studied 337 randomly children aged 24 - 48 months and infants aged 6 - 24 months in Ibb City (hemoglobin: 70 - 99 g/L). One group received a daily sachet of microencapsulated ferrous fumarate (80 mg elemental Fe) in powder form plus ascorbic acid to be sprinkled onto any complementary food eaten (sprinkles group);a control group received ferrous sulfate drops 3 times/d for 2 months (total dose: 40 mg elemental Fe). Hemoglobin and serum ferritin concentrations were measured at baseline and at the end of treatment. Results: Successful treatment of anemia (hemoglobin > 100 g/L) occurred in 58% of the sprinkles group and in 56% of the drops group, with minimal side effects in both groups. Geometric mean ferritin concentrations increased significantly in each group from baseline to the end of treatment (P Conclusion: Use of ferrous sulfate drops or a single daily dose of microencapsulated ferrous fumarate sprinkles plus ascorbicacid resulted in a similar rate of successful treatment of anemia without side effects. To our knowledge, th

Microcapsules containing disperse dyes were prepared by means of in-situ polymerization. Polyester fabrics were multiple-transfer printed and color-mix printed using those microencapsulated dyes under different process conditions. By color measurement instrument, it can be seen that the times of multiple-transfer printing are up to ten while under appropriate conditions, especially when the transfer printing time is 50 seconds and the transfer printing temperature is 180°C. On the other hand, the K/S value of each transfer printing can keep almost constant. Meanwhile, the visual effect of color- mix printing with microencapsulated disperse dyes is special in the varicolored exhibiting if compared with conventional disperse dyes.

The heat transfer of latent functionally thermal fluid in three kinds of tubes with coaxially inserted cylindrical bars is numerically researched using equivalent spe- cific heat model, and the flow fields are analyzed with field synergy field. It is found that in the tubes with coaxially inserted cylindrical bars, the heat transfer effects of functionally thermal fluid become more and more pronounced with the Ste de- creasing. This is similar to be case of functionally thermal fluid flowing in smooth straight tubes. Compared with the results receiving from smooth straight tubes, the heat transfer of functional thermal fluid in tubes with coaxially inserted cylindrical bars has been significantly enhanced. And this effect becomes more apparent as the diameter of coaxially inserted cylindrical bars increases meanwhile, however, energy consuming of the tubes shows the same trend.

Iron deficiency anemia is the most frequent nutritional deficiency disorder. Conventionally administered oral iron is associated with gastrointestinal intolerance that affects the outcomes and compliance. Liposomal iron is associated with increased absorption without causing significant adverse effects. In this review, we have discussed the technology of liposomal iron preparation, mechanisms of its absorption and clinical evidence on its utility in iron deficiency states in pregnant and non-pregnant women. Based on the available evidence, we compared liposomal iron to conventional oral iron. Encapsulation of micronized iron in liposomes is associated with lesser exposure to gastric contents, lesser interaction with food contents, no exposure to different digestive juices, targeted delivery of iron and allows lower doses to be administered in lieu of direct absorption without need for protein carriers. The available evidence suggests that liposomal iron significantly increases hemoglobin, ferritin levels in pregnant women as well as in women with iron deficiency.

The microcapsules containing the artificial diet for tropical fishes were prepared with the spray gelling method in order to prevent water environmental pollution. The carboxymethyl cellulose sodium aqueous solution, in which α-tocopherol droplets containing the powdery artificial diet were dispersed, was dropped or sprayed into the chitosan aqueous solution. Microcapsules were prepared by forming polyionic complex shell made from chitosan and carboxymethyl cellulose sodium. In the experiment, the concentration of carboxymethyl cellulose sodium (CMCNa) was mainly changed to investigate the effect on the diameters of microcapsules, the content and the microencapsulation efficiency. The microcapsules couldn’t be prepared with the concentration of carboxymethyl cellulose sodium less than 3.0 wt%. The microcapsules were the core-shell type. The diameters of microcapsules were increased with the concentration of CMCNa and the microencapsulation efficiency of ca. 100% could be obtained by the preparation method presented in this study. The microcapsules were found to be eaten well by tropical fishes and to prevent water environmental pollution.
