The enzyme linked immunosorbent assay (ELISA) is a potential tool for the determination of dextran. In this study, dextran–BSA antigens were prepared by Reductive amination method, and were confirmed by SDS-PAGE and free amino detection. The effects of coupled reaction conditions such as different oxidation degree of dextran, the reaction time were investigated and the immunity of the resulting dextran-BSA neoglycoprotein antigens were evaluated through the interaction with standard dextran antibody. The immunogen was immunized with white rabbits to obtained polyclonal antibody respectively. A general and broad class-specific Elisa detection method was developed according to Elisa theory. The method was put to use for quantitative analysis of dextran in practical saccharose samples.

A new type of hierarchically porous ZSM-5-type zeolite, Hp-ZSM, with well defined macro-/meso-/ microporous structures was facilely synthesized via a simple steam-assisted conversion route in the presence of ethanol. This novel material exhibits a tri-modal porous structure: a macroporous network with macropore sizes of 50–200 nm; a well defined mesoporous structure of pore size around 2.5 nm in the macroporous framework and a typical microporous ZSM-5 structure in the mesoporous framework. A micro-emulsion mechanism was proposed for the formation of the macroporosity where ethanol is assumed to form ‘oil’ droplets in the water phase in the presence of surfactants.

Galleys were rowed by two methods, stand and dip, or Voga culling which allowed galleys to maneuver in tight quarters. The Vale Cento is a model rendered in PoserPro used to explore naval warfare. It is a 40 oared monoreme of about 86 tons, a crew of 45, and armed with a tension trebuchet and a Greek fire projection system. The latter uses gravity fed water fountain technology to mix and project a burning ball of fire.

The study entitled “Milkfish (Chanos chanos) Scalesas an Alternative Chick Booster” aimed to test the ability of Milkfish scalesin making Chick Booster. Specifically, it attains the following: (1) to distinguish the treatments obtained from the Milkfish scalesin making chick booster; (2) to determine which treatment is most preferred by the subjects; (3) to find out if there is a significant difference among the treatments and replications in terms of the weight of the chicks; (4) to find out if it is cost effective compared to the commercial one.
In making the chick booster, the Milkfish scales were collected. Afterwards, it was washed thoroughly in plenty of water, strained through a sieve during the rinsing, sun dried then roasted. The prepared scales were then grinded and mixed to obtain the product.
The study was laid out using Randomized Complete Block Design (RCBD) with four (4) treatments and three (3) replications to evaluate the feasibility of Milkfish scales as an alternative chick booster. Two-way Analysis of Variance (ANOVA) was used to determine the difference of each treatment and replications in terms of growth rate of the subjects. There were 24 randomly selected subjects which were tested with the product.
The result showed that the first treatment with 100 grams of pure fish scales is the most preferred among the experimental group in terms of weight of the chicks with a mean of 5.74. Thus, the use of Milkfish scales as an alternative Chick Booster is feasible.
