The proliferation of disease-vector mosquitoes has been attributed to the effects of land-use change. We investigated the relationship between land use, macroinvertebrate communities, and water chemistry in water-filled containers in native forest, pasture land, and urban land at two locations (Waikanae and Paraparaumu) in the Kapiti region, New Zealand. Larvae of the endemic Culex pervigilans ...

This study's objective is to determine the factors that affect output of pig production in Manokwari Regency. survey included 30 local producers total. Direct observation and questionnaires were used gather data. The data can be analyzed using multiple regression. results showed influencing Regency breeder's age, land litter size. With an average breeder age 45.30 years with ownership 8.21 m2 s...

Climate change and land-use change are projected to be the two greatest drivers of biodiversity loss over the coming century. Land-use change has resulted in extensive habitat loss for many species. Likewise, climate change has affected many species resulting in range shifts, changes in phenology, and altered interactions. We used a spatially explicit, individual-based model to explore the effe...

Fuzzy classification techniques have been developed recently to estimate the class composition of image pixels, but their output provides no indication of how these classes are distributed spatially within the instantaneous field of view represented by the pixel. As such, while the accuracy of land cover target identification has been improved using fuzzy classification, it remains for robust t...

SCHMIDT,ROBERT M., MAMORU KUMADA, AND KIICHI SAGAWA. Cardiac output and total peripheral resistance in carotid sinus reflex. Am. J. Physiol. 221(Z) : 480-487. 197 1 .-The sensitivity of the carotid sinus baroreceptor reflex to step change in sinus pressure was studied in anesthetized dogs, with emphasis on the relative contributions of cardiac output (CO) and total peripheral resistance (TPR) i...

The total amount of CO2 released at Ischia Island has been estimated from soil gas flux measurements and from chemical composition of the gases released by fumaroles or dissolved in groundwaters. The preliminary results indicate an overall CO2 output of about 15 kg s –1 from the entire island (46 km2). The main contribution to the total output from diffuse soil degassing is about 14.8 kg s–1, f...

ESPITE extensive studies on spontaneously hypertensive rats, there have been no studies on the cardiac output except a preliminary work by Albrecht et al,4) which reported a decreasing tendency of cardiac output with age. These authors employed the Stewart-Hamilton principle for the measurement of cardiac output. An attempt was made in this study to measure cardiac output in SHR by applying an ...

Commercially available high-resolution satellite imagery from sensors such as IKONOS and QuickBird are important data sources for a variety of urban area applications including infrastructure feature extraction and land cover mapping. Land cover maps from medium and high-resolution imagery are typically generated through supervised spectral classification of multispectral imagery. Supervised cl...
