The recently derived Dutch Environmental Quality Standards (EQS) for water, soil, and sediment for approximately 170 substances have been evaluated. Three methods have been used to derive the Dutch EQS. Independent of how the EQS were derived, they are given equal weight in Dutch environmental policy. Scientifically, the three methods may deserve different weights. For example, for soil and sed...

ht + (uh+ u+ uxy)x = 0 (1.2) which were first obtained by Boiti et al [1] as a compatibility condition for a “weak” Lax pair. A Kac-Moody-Virasoro type Lie algebra for eqs. (1.1) and (1.2) were given by Paquin and Winternitz [2]. Moreover, Sen-yue Lou [3] showed that eqs. (1.1) and (1.2) do not pass the Painlevé test, both in the ARS algorithm and in the WTC approach. Equations (1.1) and (1.2) ...

We investigate the Seiberg-Witten monopole eqs. on noncommutative R4 at the large noncommutative parameter limit, in terms of the equivariant cohomology. The BPS and fixed point equations are reduced to ADHM eqs. with 0 dim. reduction of the Dirac eq. It is known that the solutions of the ADHM eqs. are isolated ones, and are classified by the Young diagram. We show the Dirac eq. is trivial, and...

Micropollutants (MPs) from municipal wastewater are frequently detected in surface waters and occur in ecotoxicologically relevant concentrations. Therefore a broadly accepted method for the assessment of MPs is needed. Here we propose a procedure for the assessment of MPs from municipal wastewater. The method suggested comprises (1) an approach for the identification of potentially polluted si...

Since 2007 about 200 to 300 fish per year--generally roach (Rutilus rutilus) also a few bleak (Alburnus alburnus) and eels (Anguilla anguilla)--have been collected from a number of English river sites and stored at -80°C to build up a Fish Tissue Archive as a resource for the monitoring of pollutants. Some of the fish from the Fish Tissue Archive from the years 2007-2011 were analyzed for subst...

In the period between December 2018 and July 2019, a series of earthquakes (EQs), including 16 Ms 5.7 Xingwen mainshock 17 June 2019 6.0 Changning mainshock, struck shale gas exploration field in southern margin Sichuan Basin. The EQs both occurred on concealed faults, which led to hundreds casualties, affected total over 160 thousand people Sichuan. aftershock sequences following were clustere...

The increasing use of parallel systems has led to the development of a number of multiprogrammed processor allocation policies. This paper analyzes the following four policies that have previously been shown to have high performance under speciic workloads: adaptive static partitioning (ASP), dynamic rst-come-rst-serve (FCFS), preemptive smallest available parallelism rst (PSAPF), and spatial e...

In this study, we report atmospheric electric field (AEF) anomalies observed around the time of earthquakes (EQs) in Japan. Using a newly developed AEF observation network with three spatially separated stations Japan (Chofu, Kakioka, and Iwaki), conducted study for two EQs that occurred within few 100 km from EQ epicenter under relatively good local weather conditions as shown by all-sky camer...
