Abstract:
The aim of this research was to gain the profile of blood gasses of green turtle (Chelonia mydas) hatch. Blood gas of the green turtle was analysed after exposuring them at 28 °C and 50% of humidity for 24 hours in a pvc tube and at 34 °C under sunlight exposured with 47% of humidity for 30 minutes. The result showed the different values of blood gas contents. This result showed indication of metabolism activities and poikilothermic adaptation of green turtle hatch. This information can be used to support for turtle hatchery in Indonesia.Keywords:

The AC conductivity of aluminium sulphate (Al2(SO4)3.16H2O) is found to be strongly humidity dependent. This property has been used to develop a humidity sensor. The AC conductance of the specially designed humidity sensor varies ~103-fold when the relative humidity changes from 22 to 88%. It is observed that the AC conductance of aluminium sulphate varies exponentially with relative humidity between 35 and 70% relative humidity levels. A transducer using aluminium sulphate may be designed for developing a humidity sensor effective between the 35 and 70% relative humidity levels. The effect of frequency on conductance is insignificant in the higher-frequency region.

It is well known that ranching
of the hatchery produced seed of
commercially important finfish and
shellfish in their natural habitat or
other suitable areas would enhance
their population. Ranching
of salmon, prawns and ababnes
is practised in U.S.A., Europe
and Japan.

This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared steelhead in relation to how they were released and the cost of placing a hatchery salmon as a potential spawner.

Millions of hatchery-reared striped bass Morone saxatilis have been stocked into the Hudson River since 1983 and into the Chesapeake Bay since 1985; these annual programs continue indefinitely. Despite the magnitude of these plantings, little attention has been paid to whether or not these hatchery-reared fish display the migratory behavior or morphological characteristics of their wild counterparts. Most of these fish were marked with coded wire tags. To examine selected biocharacteristics of hatchery-reared striped bass in the wild, we used coded wire tag detectors to identify hatchery-reared fish among striped bass captured during autumn in 1991 and 1992 in haul seines near Montauk, New York. More than 1,500 striped bass were scanned for coded wire tags each year; hatchery-reared fish composed about 3.5% of the striped bass catch in 1991 and 2.5% 1 year later. Although only about twice as many marked striped bass were stocked in Chesapeake Bay as in the Hudson River, the recapture ratio of Chesapeake Bay to Hudson River fish was 62: 1 in 1991 and 37:2 in 1992; these differences probably resulted from differences in relative survival or migratory behavior. Hatchery-reared striped bass from Chesapeake Bay showed significant (P < 0.05) differences from wild fish in 14 of 18 morphometric dimensions and in the proportion of fish with asymmetric pectoral fin ray counts, but not in the magnitude of asymmetrical fin ray counts or in condition. Hatchery-reared striped bass also displayed a pronounced increase in the incidence of broken stripedness, which may be related to the artificial environments in which they had been raised. We believe that the continued use of hatchery-reared striped bass requires additional monitoring to determine whether or not they are inferior to wild fish in such key characteristics as migratory behavior or homing fidelity.

The effect of an abrupt change in the relative humidity on the viability of airborne Mycoplasma pneumoniae has been examined. When the microbial aerosols were permitted to equilibrate in air held at either low or high humidities and were then subjected to a sudden shift to a mid-range humidity, a significant loss (>90%) of the colony-forming units per liter of aerosol occurred within 8 min. In contrast, a change in the relative humidity of more than 18% in either direction from a lethal mid-range humidity noticeably decreased the rate of biological decay. Double humidity shifts (i.e., from dry to a mid-range level and then to a high humidity range) were very detrimental, with very few survivors after 8 min. These results indicate that the biological stability of airborne M. pneumoniae may be easily modified by a sudden change in the relative humidity, such as occurs in natural atmospheres. This increased sensitivity brought about by producing changes in relative humidity through the lethal humidity range may provide a method whereby the control of these organisms in naturally contaminated indoor air environments may be eventually achieved.

Humidity is a very important factor in representing the severity of electrostatic discharge (ESD). Low humidity indicates high risk of ESD problems; high humidity indicates low risk of ESD problems. Both relative humidity and absolute humidity can represent the level of humidity: which one is more important? The reported measurement result shows that relative humidity is more important in the discharge phase. The qualitative analysis is given.
