The basal body and its associated rootlet are the organelles responsible for anchoring the flagellum or cilium in the cytoplasm. Structurally, the common denominators of the basal apparatus are the basal body, a basal foot from which microtubules or microfilaments emanate, and a striated rootlet. A study of the basal apparatus from cells of the epidermis of a sponge larva was initiated to provide a comparison with similar data on adult sponges.Sexually mature colonies of Aplysillasp were collected from Keehi Lagoon Marina, Honolulu, Hawaii. Larvae were fixed in 2.5% glutaraldehyde and 0.14 M NaCl in 0.2 M Millonig’s phosphate buffer (pH 7.4). Specimens were postfixed in 1% OsO4 in 1.25% sodium bicarbonate (pH 7.2) and embedded in epoxy resin. The larva ofAplysilla sp was previously described (as Dendrilla cactus) based on live observations and SEM by Woollacott and Hadfield.

Tofu is main food in Indonesia and its waste generally pollutes the waters. This study aims to change the waste into energy by utilizing the electric charge in the pores of tofu waste to produce hydrogen in water. The tofu pore is negatively charged and the surface surrounding the pore has a positive charge. The positive and negative electric charges stretch water molecules that have a partial charge. With the addition of a 12V electrical energy during electrolysis, water breaks down into hydrogen. The test was conducted on pre-treated tofu waste suspension using oxalic acid. The hydrogen concentration was measured by a MQ-8 hydrogen sensor. The result shows that the addition of turmeric together with sodium bicarbonate to tofu waste in water, hydrogen production increased more than four times. This is due to the fact that magnetic field generated by delocalized electron in aromatic ring in turmeric energizes all electrons in the pores of tofu waste, in the sodium bicarbonate, and in water that boosts hydrogen production. At the same time the stronger partial charge in natrium bicarbonate shields the hydrogen proton from strong attraction of tofu pores. These two combined effect are very powerful for larger hydrogen production in water by tofu waste.

ABSTRACT The time course of the renal excretion of calcium, magnesium, sodium, and potassium during sodium depletion and the rapid correction of the extracellular volume deficit was studied in normal subjects and in patients with Addison's disease (AD). The decrease in body weight was similar in the two groups, but the haematocrit value increased more in the patients with AD. Sodium depletion suppressed sodium excretion much more efficiently in normal controls than in the AD patients. Calcium excretion was roughly equally depressed in two groups. During sodium loading there was an immediate increase in renal sodium excretion in the patients with AD, whereas the sodium-retaining state generally continued for about one day in the normal controls. Urinary potassium decreased gradually during the first day of sodium loading in the normal controls but not in the AD patients. In the normal subjects calcium excretion remained low during the first day and increased on the second day of sodium loading. In the AD patients there was a gradual increase in urinary calcium during the first day of sodium loading, which did not, however, parallel the changes in urinary sodium content in individual urine samples. Urinary magnesium did not change significantly. It is concluded that the effect of adrenal steroids on renal calcium excretion is of minor importance. They may, however, to some extent induce calcium retention.
