In this paper, I argue that animal domestication, speciesism, and other modern human-animal interactions in North America are possible because of and through the erasure of Indigenous bodies and the emptying of Indigenous lands for settler-colonial expansion. That is, we cannot address animal oppression or talk about animal liberation without naming and subsequently dismantling settler colonial...

Pilot plant study showed that there is a relationship between the HRT in aeration tank and the % removal of soluble COD in the final settler if DO is not a limiting function. It was found that the % removal of soluble COD in final settler increased from 13 at HRT in aeration tank of 12 hours to 45 at HRT of 4 hours. Mathematical model was also presented in order to predict the soluble COD utili...

An iterative numerical technique has been developed to simulate in detail the dynamics of a shallow-layer gravity settler. Currently acknowledged models apply only to specific equipments at steady-state and laboratory scale [Jeelani SAK, Hartland S. The continuous separation of liquid/liquid dispersions. Chem Eng Sci 1993;48(2):239–54]. To our knowledge, no study has ever addressed the dynamic ...

Understanding settler colonialism as an ongoing structure rather than a past historical event serves as the basis for an historically grounded and inclusive analysis of U.S. race and gender formation. The settler goal of seizing and establishing property rights over land and resources required the removal of indigenes, which was accomplished by various forms of direct and indirect violence, inc...

Conventional water treatment plant generates two types of process wastes, filter back wash water and sludge. Characteristic studies of these wastes reveals that it contains high solids content, metals and bacteriological concentration, which are generally more than permissible disposable standards. Direct disposal of these wastes in to natural stream pollutes the receiving streams, affects huma...

A new 1-D model for the secondary clarifier was recently presented. The decisive difference to traditional layer models is that every detail of the implementation is in accordance with existing PDE theory. Moreover this new model does not only focus on hindered settling but also allows accounting for compressive settling. In this contribution, the behaviour of this new settler model is compared...

In a recent comment, David Albouy claims that the data series we constructed for European settler mortality in Acemoglu, Johnson and Robinson (2001) suffers from “inconsistencies, questionable judgements, and errors.” He proposes two series, for “barracks” and “campaigns,” that he claims are better measures of settler mortality, and shows his recodings weaken or eliminate the first-stage relati...

SOCIOLOGISTS INFORMED BY CRITICAL, anticolonial praxis are called to reflexively consider social realties as they are, while actively participating in social transformation. I write from my position as a settler in Misâskwatôminihk (Saskatoon) on Treaty 6 territory and the homeland of the Métis and as an engaged sociologist. By settler, I do not simply mean “non-Indigenous”—like many non-Indige...

Solids removal across two settling devices, i.e., a swirl separator and a radial-flow settler, and across a microscreen drum filter was evaluated in a fully recirculating system containing a single 150 m ‘Cornell-type’ dual-drain tank during the production of food-size Arctic char and rainbow trout. The flow through the culture tank was 4500–4800 L/min. Approximately 92–93% of the system flow e...

drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. in this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. a video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...
