Prefix hijacking, in which an unauthorized network announces IP prefixes of other networks, is a major threat to the Internet routing security. Existing detection systems either generate many false positives, requiring frequent human intervention, or are designed to protect a small number of specific prefixes. Therefore they are not suitable to protect data traffic at networks other than the pr...

The utilization of pesticides often leaves residues which potentially pollute the environment. This journal issue has been encouraging some researchers to find an environmentally friendly insecticide by a cheaper wood preservative method. The International Standard for Phytosanitary Measures 15 (ISPM 15) [1] that is adopted in wood packaging protection in Europe is not suitable for tropical cou...

Korcula's Code of Statutory regulations (from 1214, 1265, 1271 and later) contained very interesting rules of sanitary conditions in Korcula of that time. To protect the spreading of plague is prohibited contact with persons from the contaminated areas; it prohibited also entry into contaminated regions and rivers. The persons from the plague-stricken places were not allowed to enter the city. ...

Heavy metals from mining, smelting operations and other industrial processing facilities pollute wastewaters worldwide. Extraction of metals from industrial effluents has been widely studied due to the economic advantages and the relative ease of technical implementation. Consequently, the search for new and improved methodologies for the recovery of gold has increased. In this particular resea...

Concurrent multithreaded architectures exploit both instructionlevel and thread-level parallelism in application programs. A single-threaded sequencing mechanism needs speculative execution beyond conditional branches in order to exploit more instruction-level parallelism. In addition, an aggressive multithreaded architecture should also use thread-level control speculation in order to exploit ...

Government-led pollution prevention programs tend to focus on large businesses due to their potential to pollute larger quantities, therefore leaving a gap in programs targeting small and home-based businesses. In light of this gap, we set out to determine if a voluntary, peer education approach led by female, Hispanic community health workers (promotoras) can influence small and home-based bus...

Textile dying processes often pollute wastewater with recalcitrant azo and anthraquinone dyes. Yet, there is little development of effective and affordable degradation systems for textile wastewater applicable in countries where water technologies remain poor. We determined biodegradation of actual textile wastewater in biofilters containing rice husks by spectrophotometry and liquid chromatogr...

Preliminary notes Nowadays, the consideration of environmental protection viewpoints is a social obligation in all fields of life. These expectations are even more increased during the manufacturing of machine industrial products, which is why the demand for the reduction of environmental load is becoming predominant in production. This is why the application of used coolants and lubricants (CL...

The divergence constraint of the incompressible Navier–Stokes equations is revisited in the mixed finite element framework. While many stable and convergent mixed elements have been developed throughout the past four decades, most classical methods relax the divergence constraint and only enforce the condition discretely. As a result, these methods introduce a pressure-dependent consistency err...

Introduction Airborne volcanic ash is a major aviation, health, and infrastructure hazard. When ingested into aircraft engines, volcanic ash can cause engine damage or failure. For example, in December 1989, a 747 jetliner carrying 231 passengers encountered an ash cloud during an eruption of the Mount Redoubt volcano, located southwest of Anchorage, AK. Within 60 seconds of encountering the he...
