Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant. Both have been widely adopted as a measure of pollution effect. Any oxidizable material present in an aerobic natural waterway or in an industrial wastewater will be oxidized both by biochemical (bacterial) or chemical processes.
In environmental chemistry, the chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution, which in SI units is milligrams per liter ( mg / L ).
DWOP – drilling well on paper (a theoretical exercise conducted involving the service-provider managers) DWQL – dual-water quicklook log; DWSS – dig-well seismic surface log; DXC – DXC pressure pilot report
Hybrid CoE is described as a 'do tank' that conducts training courses and exercises, hosts workshops for policymakers and practitioners, and produces white papers on hybrid threats, such as vulnerabilities in an electrical grid or possible exploitation of vaguely written legislation.

Additional dedicated COI boundary security components such as a router, VPN, firewall, and IDS can be provided depending upon the requirement needs of a COI. COIs can be designed and deployed by employing the security mechanisms that are listed in the Table. Typically each individual COI may have unique characteristics and requirements.
Cyclooctadiene iridium chloride dimer is an organoiridium compound with the formula [Ir(μ 2-Cl)(COD)] 2, where COD is the diene 1,5-cyclooctadiene (C 8 H 12). It is an orange-red solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis. [1]
Dichloro(1,5-cyclooctadiene)platinum(II) (Pt(cod)Cl 2) is an organometallic compound of platinum. This colourless solid is an entry point to other platinum compounds through the displacement of the cod and/or chloride ligands .
Lim and Ong (2019) defined a community of innovation (CoI) as a group of people with a sense of camaraderie, belonging and a collective identity who are jointly facilitating innovation. [1] CoIs are groups made up of motivated individuals working together towards a common goal because they are convinced of their common cause. [3]
