Abstract. Manila Bay is one of the most significant harbors in region, enabling commerce and trade between Philippines other countries. Its abundant natural resources have provided for generations its inhabitants driven socio-economic development centuries. Like water bodies adjacent to highly urbanized cities, increased organic nutrient loading from untreated domestic, industrial, agricultural...

Monitoring and estimating pigment concentrations in water bodies have a critical role early intervention or investigation of causes for prevention. Remote sensing data are the most effective alternative due to its advantages as effortless, requiring less labor, displaying large areas single frame. Analyzing Chlorophyll-a (Chl-a) constitute important research topics because all phytoplankton con...

This work presents the utilization of MODIS data for mapping chlorophyll spatial distribution along east coast of Malaysia. Four algorithms have involved in this study which were Aiken’ algorithm, Clark-3-Bands algorithm, Gordon algorithm and Normalized Difference Chlorophyll Index (NDCI) algorithm. In this study, the maximum amount of chlorophyll concentration value of 0.38 mg m occurred durin...

A Cayley (di)graph Cay(G,S) of a group G with respect to set S ⊆ is said be normal if the image under its right regular representation in automorphism Cay(G,S), and called CI-(di)graph for every T Cay(G,S)≅ Cay(G,T), there α∈ Aut(G) such that Sα = T. finite DCI-group or an NDCI-group all digraphs are CI-digraphs, respectively, CI-group NCI-group graphs CI-graphs, respectively. Motivated by conj...

A new technique to retrieve cloud optical depth for broken clouds above green vegetation using ground-based zenith radiance measurements is developed. By analogy with the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Cloud Index (NDCI) is defined as a ratio between the difference and the sum of two zenith radiances measured for two narrow spectral bands in the visible...

The urban expansion of Teresina has caused environmental impacts on the Poti River due to occurrence eutrophication and proliferation aquatic plants in dry season year. Considering characteristics related water-quality monitoring Northeast region Brazil, from remote sensing, this study aimed evaluate performance semi-empirical algorithms Sentinel-2 data detection mapping river Teresina, Piaui, ...

The aim of this study was to examine the long-term effects of neurological decompression illness (NDCI) on recreational divers. Thirty-seven divers who had been treated for neurological decompression illness at least 2 years previously, and a control group of 50 divers with no history of decompression illness, responded to a postal questionnaire. Divers in the accident group reported more sympt...

Alteration in length of the distal ulna may provide an attractive alternative to more destructive procedures commonly used for the treatment of mechanical and degenerative problems at the distal radioulnar joint. Ulnar recession has shown effectiveness in ulnolunate impingement, triangular fibrocartilage tears, and symptomatic ulnar plus variance. It has also been effective in chondromalacia of...
