In tropical regions, intense solar radiation on seawall can lead to a high surface temperature, which far exceeds common marine species’ tolerable limits. This is a primary reason for low biodiversity on Singapore’s seawalls and therefore must be considered in eco-engineering practices. The intertidal zone of a seawall is periodically submerged and cooled by the tidal motion, and therefore can support a local ecosystem. The objective of this research is to establish a predictive model for surface temperature of seawall’s intertidal zone and use this model to study how local biodiversity is affected by the occurrence of high temperature.

A series of stellar models were evolved, all with a total mass of 0.65 M⊙, an initial carbon-oxygen core of mass 0.60 M⊙, an intermediate helium mantle and an outer hydrogen-rich envelope with mass varying from case to case. Although the most hydrogen-rich cases resulted in red giants, cases with ≲ 0.01 M⊙ in the hydrogen envelope evolved at high surface temperature. The early stages of development of these models are similar to observed central stars of planetary nebulae. The later stages (when the nebula should be very thin optically) still have a high luminosity; the relevance to ‘ultraviolet stars’ will be discussed.

DKI Jakarta area with high CO2 emission and 84,95 % of  built-up areas (year of 2009) cause urban heat island (UHI).  To overcome UHI problems, its characteristics must be known.  Trend analysis of surface temperature areas was conducted by comparison of surface temperature  spatial distribution of 2006 with 2010.  UHI analysis based on geograpical coordinates were also conducted.  High surface temperature of > 34 ºC was on inner city and decreasing to sub urban area.  High surface temperature were especially on high density bulit-up areas. Priority of  solving UHI problems are conducted on high surface temperature areas.

AbstractAn induced-collapse model [hereafter IC model; He et al. (1990)] can overcome the problems of the single star model of SN1987A. According to the IC model, there is a possibility that the SN1987A remnant will be a binary system with two neutron stars, one of them (SK-69 202) will have a strong magnetic field and a high surface temperature which favors detection as an X-ray or γ-ray pulsar. If the surface temperature of the neutron star cools down to T = 107 K, a radio binary pulsar is expected. There is also the possibility that an X-ray or γ-ray pulsar will be observed first, and only later will a radio pulsar will be detected.A newly formed neutron star is thought to have a short (millisecond) period. In this case, the core emission beam is then very large (Qiao 1992) and is thus very likely to swing in the direction of the Earth.
