Abstract This article explores the ways in which Latin American decolonial theory is drawn on to make sense of colonial legacies contemporary Africa. For theory, colonialism characterized by enforced assimilation enacted through epistemic violence. self-consciously rejects thinking about as historically specific favor more abstract concept coloniality. When travels Africa, its emphasis obscures...

AODV is a reactive MANET routing protocol that is vulnerable to a dramatic collapse of throughput when malicious intruders flood the network with bogus route requests. We introduce a simple mechanism to resist such attacks that can be incorporated into any reactive routing protocol. It does not require expensive cryptography or authentication mechanisms, but relies on locally applied timers and...

In this piece I explore how Bhambra and Holmwood’s Colonialism Modern Social Theory implies three different questions that can be asked concerning the connections between colonialism social theory. With reference to their discussion of Durkheim, suggest answers they offer these possible return us what Kurasawa termed ‘constitutive paradox’ Durkheim’s relation colonialism, namely a mix political...

Utilization of pozzolanic materials (fly ash, slag, zeolite, metakaolin, microsilica and more) in the manufacturing of cement and concrete has increased considerably over the last decades. Another option is to use concrete containing sulfate resisting cement. This could help minimize the harmful impacts on concrete exposed to an aggressive environment. The issue of the deteriorative impact of t...

Executive functions (EFs) make possible mentally playing with ideas; taking the time to think before acting; meeting novel, unanticipated challenges; resisting temptations; and staying focused. Core EFs are inhibition [response inhibition (self-control--resisting temptations and resisting acting impulsively) and interference control (selective attention and cognitive inhibition)], working memor...

The race towards new heights and architecture has not been without challenges. Tall structures have continued to climb higher and higher facing strange loading effects and very high loading values due to dominating lateral loads. The design criteria for tall buildings are strength, serviceability, stability and human comfort. But the factors govern the design of tall and slender buildings all t...

the present article seek to investigate the function of elliptical steel damper function in steel frames seismic resisting. the elliptical damper is a kind of earthquake energy dissipater in structure which acts based on the steel yielding feature. thus, this damper in frame lateral displacement mechanism is expected to have a satisfying hysteretic behavior in terms of energy absorption is on a...
