This study comprehensively investigated the distribution, source identification, and potential ecological risk of heavy metals (As, Ni, Pb, Cd, Cr, Cu, Zn) in surface sediments Mongla port area Bangladesh. The sediment samples were collected from ten sampling points during wet dry season analyzed by atomic absorption spectrophotometer. average concentration metal was higher (11.36 to 118.55 mg/...

sea surface topography (sst) by definition is the separation between the geoid and the mean sea level (msl). the separation between the geoid and msl is caused by various non-gravitational physical effects. if determination of the geoid as the zero point of the height systems from the tide gauge observation be the goal, it is necessary that the affect of the physical effect be precisely compute...

Abst rac t We develop a new governance perspective on port–hinterland linkages and related port impacts. Many stakeholders in a port’s hinterland now demand tangible economic benefits from port activities, as a precondition for supporting port expansion and infrastructural investments. We use a governance lens to assess this farsighted contracting challenge. We find that most contemporary econo...

Cement is a key construction material in civil and geotechnical engineering. However, its application for stabilization of marine sediments needs further investigation. This paper tests the effects varied amounts Portland cement added to soil samples on leaching tributyltin (TBT) from contaminated evaluates pH level. Identifying best combinations / slag Kiln Dust (CKD) effective treatment centr...

INTRODUCTION Single-port thoracoscopic surgery has widened the current minimally invasive surgical techniques toward more less invasive procedures in terms of reducing the number of incisions. However, the current status of oncologic outcome with this technique is not well known for lung cancer surgery. The purpose of this study is to evaluate the oncologic outcomes in early stage lung cancer f...
