Coral Tissue Thickness as a Bioindicator of Mine-Related Turbidity Stress on Coral Reefs at Lihir Island,Papua New Guinea
Coral Tissue Thickness Bioindicator Mine-Related Turbidity Stress Coral Reefs Lihir Island Papua New Guinea
2015/7/15
Work described here assessed the feasibility of using variations in tissue thickness in massive Porites corals as a bioindicator for mine-related sediment stress. We examined parameters influencing co...
Little is known of New Guinea’s deep benthic communities. In
fall 2010, the Muséum national d’Histoire naturelle, Institut de Recherche pour le
Développement, and University of Papua New ...
Lithospheric-scale structures in New Guinea and their control on the location of gold and copper deposits
Lithospheric-scale structures New Guinea location of gold copper deposits
2015/1/6
The locations of major gold and copper deposits on the island of New Guinea are considered by many to be controlled by a series of transfer faults that strike N–S to NE–SW, perpendicular to the long a...
Preliminary Geophysical Investigation to Delineate the Groundwater Conductive Zones in the Coastal Region of Akwa Ibom State, Southern Nigeria, around the Gulf of Guinea
Freshwater Saltwater Ferruginized and Saline Sands VES
2013/3/11
This paper presents the first work of its kind within the confines of the study area. It unravels the distribution of the layers of conductive sand and their depths of interaction between freshwater f...
Effects of Ca2+ and HCO3- on Capacitation, Hyperactivation and Protein Tyrosine Phosphorylation in Guinea Pig Spermatozoa
Capacitation Hyperactivation Tyrosine Phosphorylation Sperm
2016/4/29
In our previous report, we demonstrated that the tyrosine phosphorylation of sperm proteins (TPSP) of guinea pig was associated with capacitation and hyperactivation (CAHA), and Ca2+ and HCO3- were re...
The Seasonal Upwelling in the Gulf of Guinea Due to Remote Forcing
Seasonal Upwelling Remote Forcing Gulf of Guinea
2009/2/23
A linear model on an equatorial β plane is integrated over a 120-day period in a basin that approximates the tropical Atlantic Ocean. An increase in the westward wind stress of 0.025 N m−2 in th...
Propagation of a 14.7-Day Wave along the Northern Coast of the Guinea Gulf
14.7-Day Wave the Guinea Gulf Northern Coast
2009/2/11
Long time series of sea level and sea surface temperatures measured at different coastal stations along the northern coast of the Gulf of Guinea are analyzed statistically. The results indicate that p...
Identification of the Fortnightly Wave Observed Along the Northern Coast of the Gulf of Guinea
Fortnightly Wave Gulf of Guinea
2009/2/6
Numerical calculations of coastally trapped wave modes along the northern coast of the Gulf of Guinea using representative bottom topography and continuous stratification on a β-plane were carried out...
Seasonal Variations of the Subsurface Thermal Structure in the Gulf of Guinea
Seasonal Variations Gulf of Guinea Subsurface Thermal Structure
2009/2/6
The subsurface thermal structure in the Gulf of Guinea is analyzed using the historical hydrographic data file. Of particular interest is the rapid vertical displacement of the thermal structure from ...
Capacitation-associated Changes in Protein-tyrosine-phosphorylation, Hyperactivation and Acrosome Reaction in Guinea Pig Sperm
Acrosome Reaction Capacitation Hyperactivation Tyrosine Phosphorylation Semen
2016/4/27
The aim of this study was to evaluate the effects of Ca2+, HCO3- and BSA on the in vitro capacitation-associated protein tyrosine phosphorylation, hyperactivation and acrosome reaction in guinea pig s...
The Papua New Guinea tsunami of 17 July 1998: anatomy of a catastrophic event
The Papua New Guinea tsunami 17 July 1998 a catastrophic event
2009/12/30
The Papua New Guinea (PNG) tsunami of July 1998 was a seminal event because it demonstrated that relatively small and relatively deepwater Submarine Mass Failures (SMFs) can cause devastating local ts...
Synthetic aperture radar (SAR)-based mapping of volcanic flows:Manam Island,Papua New Guinea
Synthetic aperture radar SAR-based mapping volcanic flows Manam Island
2009/12/17
We present new radar-based techniques for efficient identification of surface changes generated by lava and pyroclastic flows, and apply these to the 1996 eruption of Manam Volcano, Papua New Guinea. ...
Effect of classic preconditioning and diazoxide on endothelial function and O 2 and NO generation in the post-ischemic guinea-pig heart
Endothelial dysfunction Nitric oxide Ischemic preconditioning Oxygen free radicals Ischemia Reperfusion
2014/3/31
A hypothesis was tested that a reaction product between superoxide (O2
) and nitric oxide (NO) mediates post-ischemic
coronary endothelial dysfunction that ischemic preconditioning (IPC) protects...
