The case study presented in the paper is first field to find microplastic (MP) particles both grey water (GW) and post-treatment sewage (TS) samples, which can also be legally discharged into specially protected areas. Compiling a data set of 50 samples collected from GW TS 5 transport ships involved study, we show that mean number separated microparticles n = 72 per litre, 51 litre. Of 614 par...

it is well known that, contaminant transportation is a major problem in coastal zones and has to be faced when coastal structures are being planned. sea pollution not only causes environmental damage, but also impacts quality and population of sea resources. oil is the most important pollutant, pollutants emanating from industries, ships, drilling and exploration in the seabed, ship sewage, tox...

FcgammaR-mediated phagocytosis of IgG-coated particles is a complex process involving the activation of multiple signaling enzymes and is regulated by the inositol phosphatases PTEN (phosphatase and tensin homolog deleted on chromosome 10) and SHIP-1 (Src homology [SH2] domain-containing inositol phosphatase). In a recent study we have demonstrated that SHIP-2, an inositol phosphatase with high...

Wastewater consists of a complex mixture of substances. During wastewater treatment these harmful substances can be eliminated or degraded. However, persistent compounds released with the treated sewage effluents enter the environment and pose a risk to animal and human life. To determine the potential risks involved, screening tests are needed to monitor wastewater for potential toxic contamin...

This survey discusses recent developments in the context of spherical designs and minimal energy point configurations on spheres. The recent solution of the long standing problem of the existence of spherical t-designs on S with O(td) number of points by A. Bondarenko, D. Radchenko, and M. Viazovska attracted new interest to this subject. Secondly, D. P. Hardin and E. B. Saff proved that point ...

Microalgal blooms can result from anthropogenic nutrient loadings in coastal ecosystems. However, differentiating sources of nutrients remains a challenge. The response of phytoplankton and benthic microalgae (BMA) to nutrient loads was compared across tropical tidal creeks with and without secondary treated sewage. Primary productivity in the water column was limited by nitrogen availability i...

Sewage is a kind of ideal low-temperature heat sources. Sewage heat source pump system uses heat energy in sewage, and it is a method of utilizing sewage resources. In this article we analyze sewage’s characteristics and sewage source heat pump system; introduce its practical applications in sewage treatment plants in China, analyze its technical and economic characteristics, and discuss its ap...

The efficiency of constructed wetland to treat weak and medium primary sewage effluent was tested under three rates of sewage inflow and two types of growing plants (i.e., leaf cattail and common reed). The capability of the wetland to remove COD, BOD, TSS, TDS and F. coliform from the primary weak sewage increased with decreasing the rate of the sewage inflow from 12 L/hr. to 6L/hr., with litt...
