A social archaeology of colonial war in Ethiopia

[EN] The archaeology of twentieth-century warfare, with its focus on Western armies and military issues, has often neglected indigenous experiences of war and social aspects, particularly the role of women in reproducing culture through material practices in situations of great distress. In this article, we propose a postcolonial examination of imperialistic war in Ethiopia. We study the cave of Zeret, the refuge of a large guerrilla group that was massacred by the Italian colonial army in 1939. Using the material evidence available, life underground is described, as well as the military events that led to the destruction of the place and the killing of most of its inhabitants. We argue that archaeology can be a way of revealing, with material facts, the brutality of fascism and colonialism. Finally, drawing upon Spivak and Derrida, we ask: What are the ethical problems of representing the voice of the subaltern? What is the role of materiality in evoking her presence?[ES] La arqueología de la guerra en el siglo XX, al centrarse en ejércitos occidentales y cuestiones militares, ha dejado de lado experiencias indígenas de la guerra y las cuestiones sociales, particularmente el papel de las mujeres en reproducir la cultura a través de prácticas materiales en situaciones de gran estrés.

Обоснование выбора электродвигателя и схемы его включения для системы точного поддержания скорости

Рассматривается применение в системах точного поддержания скорости различных синхронных электродвигателей. В результате сравнения рекомендовано применение в таких системах конденсаторного синхронного реактивного двигателя с трехфазными обмотками статора. Это позволяет упростить и удешевить систему точного электропривода и повысить ее надежность

New insights and changing paradigms in the regulation of vitamin A metabolism in development

This is the peer reviewed version of the following article: Shannon, S. R., Moise, A. R., & Trainor, P. A. (2017). New insights and changing paradigms in the regulation of vitamin A metabolism in development. Wiley Interdisciplinary Reviews. Developmental Biology, 6(3), 10.1002/wdev.264, which has been published in final form at http://doi.org/10.1002/wdev.264 This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Vitamin A and its active metabolite retinoic acid are essential for embryonic development and adult homeostasis. Surprisingly, excess or deficiency of vitamin A and retinoic acid can cause similar developmental defects. Therefore, strict feedback and other mechanisms exist to regulate the levels of retinoic acid within a narrow physiological range. The oxidation of vitamin A to retinal has recently been established as a critical nodal point in the synthesis of retinoic acid, and over the past decade, RDH10 and DHRS3 have emerged as the predominant enzymes that regulate this reversible reaction. Together they form a codependent complex that facilitates negative feedback maintenance of retinoic acid levels and thus guard against the effects of dysregulated vitamin A metabolism and retinoic acid synthesis. This review focuses on advances in our understanding of the roles of Rdh10 and Dhrs3 and their impact on development and disease
