The education of embedded system for students is popular in many institutes or universities recently. In this paper, the Advanced RISC Machine 9 (ARM9) based software called android developer suite (ADS) is combined with DMA 2440 educational kit to let students practice theoretical and experimental knowledge of embedded systems. The ADS will be illustrated at first then an example of camera app...

Android, originally meaning “robot”, is a mobile operating system using a modified version of the Linux kernel. It was initially developed by Android Inc., a firm later purchased by Google,[?]and lately by the Open Handset Alliance[?]. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries.[8] It empolys the software stack arc...

One of the ways to increase production for aquaculture is through cultivation monosexuals by ensuring genital reversal from which energy reproduction diverted towards growth. Masculinization has been identified as one most prominent techniques, where sex development was directed female male. This approach only altered phenotype and not genotype. The red claw crayfish (Cherax quadricarinatus) a ...

We report the development and validation of a novel in vivo biomarker test for waterborne androgens. During breeding, male sticklebacks (Gasterosteus aculeatus) manufacture a glue protein, spiggin, in their kidneys that they use to build their nests. Spiggin production is under the control of androgens. Until now, however, it has only been possible to quantify its production by measurement of t...

A simple and sensitive direct radioimmunoassay for tonin (EC.3.4.99.-) has been developed. This assay incorporates a modified and convenient poly(ethylene glycol) technique for separation of free from bound tonin. A rabbit antiserum in a final dilution of 1:160,000 was used and the purified tonin was labelled with 125I by using a lactoperoxidase method. It detects 20 pg of immunoreactive tonin ...

In many species of aquaculture importance, all-female and sterile populations possess superior productivity due to faster growth and a relatively homogenous size of individuals. However, the production of all-female and sterile fish in a large scale for aquaculture is a challenge in practice, because treatments necessary for gynogenesis induction usually cause massive embryonic and larval morta...

The biologic characteristics and susceptibility to steroid ther apy were determined for multiple mammary tumors induced in Sprague-Dawley rats by single intragastric doses of DM HA.3 Tumors were produced in 70-78% of 1016 rats within 120 days of administration of 15, 20, or 30 mg of DMBA. Mortality was 20% in rats given the highest dose. Only 52-63% of the rats had tumors usable for experimenta...

We have previously shown that exposure to exogenous androgens causes female sticklebacks (Gasterosteus aculeatus) to produce the glue protein, spiggin, in their kidneys. This protein can be quantified by an enzyme-linked immunosorbent assay developed and validated at the Centre for Environment, Fisheries and Aquaculture Science. Here we report the development of an in vivo test for the detectio...
