Organic solid wastes were treated in various types of methanogenic bioelectrochemical reactors, equipped with an external electrochemical system to control electron flow and improve microbial activity. At a high organic loading rate, cathodic bioelectrochemical reactors demonstrated greater decomposition of artificial garbage slurry and higher methane production than both anodic bioelectrochemi...

Why not treat the mother-infant dyad, rather than infant alone, as achieving vitamin D sufficiency is equally important for the mothers. Compliance with daily oral vitamin D supplementation of infants is documented to be very poor even in the West [4,5]. Exposing infants to sunlight may be a more difficult proposition than medicinal supplements. While the natural way of augmenting the vitamin D...

Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

a selective and sensitive method for determination of cadmium and zinc is presented. the method is based on adsorptive accumulation of the complexes of cd (ii) and zn (ii) ions with 4-amiono-5-methyl-2,4-dihydro-3h-1,2,4-triazol-3-tion (mmtt) onto hanging mercury drop electrode (hmde), followed by reduction of the adsorbed species by voltammetric scan using differential pulse modulation. the li...

Online communities are popular sites for collective sensemaking. This study explores sensemaking in one such community following the closure of Olint Corp, a highly successful Jamaican investment club. After Olint’s disbanding, Jamaicans reconnected through online communities to make sense of their financial losses, to make sense of Olint – seen variously as an altruistic endeavour, a global cu...

Nitroalkenes are easily accessible in high variety by condensation of aldehydes with aliphatic nitroalkanes. They belong to the group of activated alkenes that can be hydrodimerized by cathodic reduction. There are many olefins with different electron withdrawing groups used for cathodic hydrodimerization, but not much is known about the behaviour of the nitro group. Synthetic applications of t...

In electrophoretograms of creatine kinase (CK; EC 2.7.3.2) in patients' blood, a band, presumably of mitochondrial origin, is occasionally observed on the cathodic side of the CK-MM fraction. We studied the implications of this phenomenon in rats exposed to hypoxic conditions. In the hypoxic cardiac muscle, the proportions of CK-MB and CK-MM were not significantly different from controls, but t...

The design of cathodic protection systems normally relies on a combination of experience, experimental data and heuristics. However, problems and failures of CP systems not only has an economic cost, it can also present a threat to life and the environment. This paper will describe the application of a software system designed to simulate the performance of cathodic protection systems and predi...

Using FEM during the design of cathodic protection system can optimize the cathodic protection system and forecast the distribution of potential in real marine environment. A single bar was modeled for which protection was provided by an anode located in different places. Through analysis of each unit and synthesis in the whole area, mathematical model of 3-D finite element was constructed. Pot...
