As a center of textile industry in Indonesia, city Pekalongan faces environmental issue due to wastewater effluent from industry. The contains dye, mostly synthetic used for coloring the fabrics. One dyes commonly is sulphur blue producing dark color. simple methods reduce dye adsorption. Cuttlefish bone was as adsorbent. It abundantly available and cheap because it waste fishing effect acid al...

Irradiation leads to immunosuppression, hemopoiesis injury as well as sub-health of human being. The protective and therapeutic effects of cuttlefish ink on hemopoiesis in 60Co gamma radiated model mice were investigated. One hundred and twenty female ICR mice aged 6 weeks (20-24g) were randomly divided into five groups: the control group, the model group, and the low, medium, high dosage group...

Sound is a widely available and vital cue in aquatic environments, yet most bioacoustic research has focused on marine vertebrates, leaving sound detection in invertebrates poorly understood. Cephalopods are an ecologically key taxon that likely use sound and may be impacted by increasing anthropogenic ocean noise, but little is known regarding their behavioral responses or adaptations to sound...

Cephalopods are sensitive to the linear polarization characteristics of light. To examine if this polarization sensitivity plays a role in the predatory behavior of cuttlefish, we examined the preference of Sepia officinalis when presented with fish whose polarization reflection was greatly reduced versus fish whose polarization reflection was not affected. Cuttlefish preyed preferably on fish ...

Porous three-dimensional hydroxyapatite scaffolds were synthesised from aragonitic cuttlefish bones via a microwave based technique. Due to its close similarity to the mineral phase found in the natural human bone matrix, synthetically produced hydroxyapatite is considered a viable apatite substitute for natural bone in a number of biomedical applications. The X-ray diffract ion data confirms t...

Flounders and cuttlefish have an impressive ability to change colouration, for camouflage and, in the case of cuttlefish, for communication. We pursue the hypothesis that these diverse patterns are created by combining a small number of distinct pattern modules. Independent component analysis (ICA) is a powerful tool for identifying independent sources of variation in linear mixtures of signals...

OBJECTIVE The aim of the study was to compare the haematological and biochemical profiles of eight sighthound breeds. DESIGN Samples were taken from 192 individuals of the sighthound breeds (Whippet, Greyhound, Italian Greyhound, Sloughi, Saluki, Borzoi, Pharaoh Hound and Azawakh). Routine haematological and biochemical examinations were performed and the results were evaluated statistically....

When Pharaoh refused to supply straw, productivity plummeted in the Egyptian brick industry. But Pharaoh had other concerns. Anyway, the costs fell on Israelites, not Egyptians. Productivity improvement in the health sector is similarly constrained by competing objectives, and by the distribution of resulting gains and losses. Furthermore, health services have value only insofar as they improve...
