El siglo XX ha traído un desarrollo sin precedentes en la historia de la humanidad con avances impresionantes en todas las disciplinas de la ciencia y de la técnica. Sin embargo dichos avances no han sido algo gratuito, sino que han tenido un precio que no sería descabellado considerar que, bajo determinados prismas, ha sido excesivo. Durante los últimos 100 años, la población humana en la Tierra se ha multiplicado por un factor de 4 (pasando de 1.600 millones de personas en 1.900 a los más de 6.000 millones de la actualidad). Sin embargo el consumo de agua se ha multiplicado por 9 en el mismo periodo y el consumo de energía por 16, y ello con una degradación asociada del medio ambiente y los recursos naturales, en general, muy significativa. Palabras clave.-Energía solar, Desalación solar. ABSTRACTThe XX century has brought an unprecedented development in the history of humanity with impressive advances in all disciplines of science and technology. But these progresses have not been something free, but have had a price that would not be unreasonable to consider that, under certain prisms, has been excessive. During the past 100 years, the human population on earth has increased by a factor of 4 (from 1600 million in 1900 to over 6,000 million today). However water consumption has increased by 9 in the same period and power consumption by 16, and therefore associated with a degradation of the environment and natural resources in general, very significant.

Implicações da noção de consciência histórica nas ciências humanas e sociais: um modo de projeção para o futuro e de posição em relação ao passado Resumo: O presente texto, de caráter bibliográfico, discute o problema da consciência histórica com o objetivo de pensar o sentido dessa expressão na atualidade e as variações que esse conceito adquiriu ao longo da história das Ciências Humanas e Sociais, com ênfase no século XX. A hipótese é que a discussão a respeito da consciência histórica passou a se ocupar, na modernidade, com uma múltipla relatividade de pontos de vista, o que é destacado por Gadamer em sua análise sobre os preceitos implicados na definição do que significa “ter senso histórico”. É defendida a tese, portanto, de que a noção de consciência histórica não se limita ao conhecimento das experiências vivenciadas no passado, mas se apresenta como condição de possibilidade de projetar o futuro e se posicionar em relação ao passado, especialmente no que diz respeito às ciências humanas e sociais. A defesa desta ideia central é realizada por meio de dois gestos reflexivos, com apresentação, primeiramente, do marco teórico da consciência histórica e, posteriormente, de suas implicações na constituição das Ciências Humanas e Sociais. Palavras-chave: Ciências humanas e sociais. Senso histórico. Passado. Futuro. Implications of the notion of historical consciousness in human and social sciences: a mode of projection for the future and position in relation to the past Abstract: This bibliographic text discusses the problem of historical consciousness with the purpose of thinking about the meaning of this expression in the present time and the variations that this concept has acquired throughout the history of the Humanities and Social Sciences, with emphasis on the twentieth century. The hypothesis is that the discussion about historical consciousness has come to concern itself, in modernity, with a multiple relativity of points of view, which is highlighted by Gadamer in his analysis of the precepts involved in defining what “having a historical sense” means. Therefore, the thesis that the notion of historical consciousness is not limited to the knowledge of past experiences is defended, but is presented as a condition of possibility of projecting the future and positioning itself in relation to the past, especially with regard to humanities and social sciences. The defense of this central idea is made through two reflexive gestures, presenting, first, the theoretical framework of historical consciousness and, later, its implications in the constitution of the Human and Social Sciences. Keywords: Human and social sciences. Historical sense. Past. Future.

People have been visiting and living in the Victorian Grampians, also known as Gariwerd, for thousands of generations. They have both witnessed and caused vast environmental transformations in and around the ranges. Gariwerd: An Environmental History of the Grampians explores the geological and ecological significance of the mountains and combines research from across disciplines to tell the story of how humans and the environment have interacted, and how the ways people have thought about the environments of the ranges have changed through time. In this new account, historian Benjamin Wilkie examines how Djab wurrung and Jardwadjali people and their ancestors lived in and around the mountains, how they managed the land and natural resources, and what kinds of archaeological evidence they have left behind over the past 20 000 years. He explores the history of European colonisation in the area from the middle of the 19th century and considers the effects of this on both the first people of Gariwerd and the environments of the ranges and their surrounding plains in western Victoria. The book covers the rise of science, industry and tourism in the mountains, and traces the eventual declaration of the Grampians National Park in 1984. Finally, it examines more recent debates about the past, present and future of the park, including over its significant Indigenous history and heritage.

O artigo objetiva problematizar modelos hegemônicos de feminilidade a partir da história de vida de duas mulheres que experienciaram o sertão às margens do rio São Francisco (MG), habitando o município homônimo ao rio. Busca ainda entender como elas representam a si mesmas e a outras mulheres; como foram construídas as relações de gênero e os sentidos que constituem o feminino no sertão norte-mineiro na primeira metade do século XX. Partimos da compreensão de que as relações de gênero não são estáticas e permanentes e que as representações acerca do feminino são históricas, ou seja, não é possível generalizar um modelo de feminilidade para todos os estratos sociais e para todos os contextos geo-históricos. Palavras-chave: Gênero. Mulheres. Sertão. MARIA, MARIA: life histories of women in the backwoods of the São Francisco (MG) Abstract: The article aims to problematize hegemonic models of femininity from the life history of two women who experienced the backwoods on the banks of the São Francisco river (MG), inhabiting the homonymous municipality to the river. Also, it seeks to understand how they represent themselves and other women; how the gender relations were built and the meanings that constitute the feminine in the north of Minas Gerais backwoods, in the first half of the twentieth century. We start from the understanding that gender relations are not static and permanent and that the representations about the feminine are historical, that is, it is not possible to generalize a model of femininity for all social strata and for all geohistorical contexts. Keywords: Gender. Women. Backwoods.

Abstract There is no question that the American public has an unabashed appetite for history. This is demonstrated in numerous ways from bestsellers by popular historians to tourism at historic sites and museums to the popularity of films and other media depicting versions of the past. Although historians might think that the discourse presented in most of these forums is simplistic and stilted, little doubt exists that it is passionate. This discussion explores a few of the issues affecting the public's deep fascination with the past, especially in the context of the history of science and technology, and the presentation of these issues in the Smithsonian Institution. These thoughts are tentative and speculative, but, I hope, stimulating and worthy of further consideration.

O siqueirismo se tornou um derivativo de uma palavra que era comum desde a criação do Estado nos meios políticos. Com a configuração de um grupo político praticamente hegemônico no Tocantins, os políticos, sejam deputados, prefeitos, vereadores e senadores ligados ao grupo de Siqueira Campos eram chamados de siqueiristas. Desta forma objetivamos fazer uma análise do siqueirismo comparativamente a outras formas de dominação, na perspectiva weberiana, no Brasil contemporâneo. O interesse é pontuar, em um recorte deliberado de algumas formas de poder que possam servir à percepção do que é o siqueirismo no Tocantins e compará-lo com outros personagens da política brasileira na segunda metade do século XX.   PALAVRAS-CHAVE: Tocantins; siqueirismo; dominação; política.     ABSTRACT Siqueirism has become a derivative of a word that was common in political circles since the creation of Tocantins state. With the configuration of a practically homogeneous political group in Tocantins, the politicians that were affiliated to Siqueira Campos were called “siqueiristas”, whether they were congressmen, mayors, councilman or senators. Thus, we aim to make an analysis of siqueirismo with respect to other forms of domination in contemporary Brazil using a Weberian perspective. Our interest is to point which forms of power can be used to built a perception of what is siqueirism and compare it to other political characters from Brazilian history of the mid-late 20th century.   KEYWORDS: Tocantins; siqueirism; domination; politics.     RESUMEN El siqueirismo se convirtió en un derivado de una palabra que era común desde la creación del Estado en los círculos políticos.

De esta manera se pretende analizar la siqueirismo en comparación con otras formas de dominación, en la perspectiva de Weber, en el Brasil contemporáneo. El interés es anotar en un corte deliberado de algunas formas de poder que puede servir a la percepción de lo que se siqueirismo en Tocantins y compararlo con otros personajes de la política brasileña en la segunda mitad del siglo XX.     PALABRAS CLAVE: Tocantins; Siqueirismo; Dominación; Política.

Luego de la Independencia, la construcción iconográfica devino en indispensable por la necesidad de educar en la historia patria desde un punto de vista vernáculo. Sin embargo fueron extranjeros los primeros que se abocaron a la investigación y compendio de la historia patria desde sus orígenes.Aquellos textos, sin imágenes aún, se utilizaron en la incipiente educación peruana del siglo XIX. A principios del siglo XX aparecieron en el Perú los primeros textos escolares ilustrados, los uales incorporaron imágenes tomadas de publicaciones foráneas, algunas de ellas con una visióneuropeizante de lo acontecido en estas tierras. Otras publicaciones menos idealizadas contribuyeron,  con sus dibujos y grabados, a la historia visual del país, y cuando fueron incorporados a los libros paraeducación básica coadyuvaron a crear el imaginario colectivo. El presente artículo muestra algunas fuentes iconográficas que sirvieron para instruir a la población escolar de principios del siglo XX, varias tomadas como válido referente en diversas situaciones de la historia del Perú, preguntándose cómo pueden haber influido en la conciencia nacional.

But foreigners were the first to set about theresearch and compilation of national history from its origins.

Other publications less idealized helped with his drawings and print to the visual history of the country, and when they were incorporated into the books for basic education, helped create a collective imagination. This article shows some iconographic sources that served to educate the school population in the early twentieth century, several taken as a valid reference in various situations in the history of Peru, wondering how it may have influenced national consciousness.

Effective Remedy

A long history of oil and gas development in Texas has made the state the number one energy producer in the United States, and the bulk of that energy is produced from fuels acquired by drilling into the vast natural resources that sit below the state. As a side effect of this long history, it is common for the surface and mineral estates in Texas to be severed, and many severances happened several generations ago. This history has spread mineral interests between dozens of owners in some cases, many who are unknown and cannot be found. Absentee ownership has diluted the value of these fractionalized interests and has made use by their non-absentee counterparts more difficult. Existing laws that have been used in the past to clear absentee owners from title have not been effective in the context of a severed mineral estate, as those laws evolved primarily to address surface interests, or to accomplish other purposes with only incidental effect on land titles. This Comment discusses the inadequacy of the current methods used in Texas to remove absentee owners from mineral titles and illustrates the need for a more effective remedy. It then offers a dormant mineral act that suits the unique cultural and economic needs of Texas and addresses the growing fractionalization of Texas’s mineral estates.

Iran is home to some of the world’s earliest civilizations. The Ashkanian dynasty (550–330 BCE) unified Iran as a superpower empire. It was the largest empire yet seen and the first world empire where the Great Cyrus ruled from the Balkans to North Africa and Central Asia. Subsequently, Iran was invaded by the Macedonians, Arabs, Turks and the Mongolians over the course of its history. During those times, Iran lost much of its territory until a reduced Iran was formed in the nineteenth century CE. Despite the invasions, Iran did not lose its heritage from its previous civilizations, but rather incorporated aspects of the new civilizations into its cultural fabric. Iran has always played an effective role in the natural sciences, medicine, mathematics, astronomy, philosophy and also in mineralogy and gemology. At times, Iran was at the forefront of science and technology, including mineralogy and gemology, which went through stages of development. The first and second stages occurred before and after the introduction of Islam, respectively. More than 30 books were written about minerals and gems during the ancient and Islamic Iranian periods. Those books can be classified into three main groups where the first group included accounts of precious stones, minerals, gems and metals. The second group of books focused on natural history, chemistry and precious stones. The third group of books discussed medicine, pharma-chemistry and medical properties of minerals. The most famous texts were written by early Iranian scientists such as Avicenna, Biruni, Jabir Ibn Hayan, Kandi and Razi. Iran’s role at the forefront of science and technology (including mineralogy and gemology) declined after the collapse of the Safavid dynasty (1501–1736 CE). But recently, during the past 50 years, Iran has made considerable advances in science and technology through education, training and research. This will open a new age of development for Iran in the twenty-first century in science and technology as well as in mineralogy and gemology
