The practice of "land grabbing", or the large-scale hoarding of fertile lands in developing countries by rich countries, transnational corporations and individuals, in order to grow food beyond their borders, is today reaching historically unparalleled figures. Although the dominant discourse vindicates this process as an opportunity for the countries that are recipients of these practices, numerous voices warn about the role played by this phenomenon in the (re-) emergence and development of global and local problems. The objective of this work is to demystify the theoretical, political and historical proposal endorsed and promoted by international organizations such as the International Monetary Fund and the World Bank in the light of conflicts over the use and ownership of land. Together, food security, impacts on small and medium-sized local farmers and migration are generating the current model of international land grabbing.
La práctica del "acaparamiento de tierras", o el acaparamiento a gran escala de tierras fértiles en países en desarrollo por parte de países ricos, corporaciones transnacionales e individuos, con el fin de cultivar alimentos más allá de sus fronteras, está alcanzando hoy cifras históricamente incomparables. Aunque el discurso dominante reivindica este proceso como una oportunidad para los países que son receptores de estas prácticas, numerosas voces advierten sobre el papel desempeñado por este fenómeno en la (re) aparición y desarrollo de problemas globales y locales. El objetivo de este trabajo es desmitificar la propuesta teórica, política e histórica respaldada y promovida por organizaciones internacionales como el Fondo Monetario Internacional y el Banco Mundial a la luz de los conflictos sobre el uso y la propiedad de la tierra. Juntos, la seguridad alimentaria, los impactos en los pequeños y medianos agricultores locales y la migración están generando el modelo actual de acaparamiento internacional de tierras.

Abstract Brunei is a small tropical country -located in Southeast Asia- for which there are no previous bibliometric studies. Here we analyze papers published by Brunei scientists from 1973 to 2016 in the Science Citation Index Expanded and compare results with other tropical countries. We identified 1 547 publications and 11 document types. The most productive categories were ecology, multidisciplinary geosciences, inorganic and nuclear chemistry, and environmental sciences. Singapore Medical Journal published most of these papers, and the three most productive institutions were Universiti Brunei Darussalam, RIPAS Hospital, and Universiti Teknologi Brunei. UK and Malaysia were the most frequent collaborating countries. M.A. Ali from the Universiti Brunei Darussalam was the most prolific author and a Brunei independent article written by C.K. Morley from the Universiti Brunei Darussalam in 2002 had the highest number of citations of the whole period and the highest number in 2016. The tropical countries of Central America and Asia have a few similarities but also important differences, and both are highly heterogeneous in scientific organization and productivity. Rev. Biol. Trop. 66(3): 1090-1100. Epub 2018 September 01.

While radioactive isotope analysis has proved to be a useful method in disciplines such as archaeology and forensic anthropology, more recently, radiocarbon dating has allowed for a more nuanced biological profile of human skeletal remains. Radiocarbon dating has been made possible by the above ground nuclear bomb test conducted in 1963, which raised the level of atmospheric radiocarbon concentration to almost twice the natural level. Because the annually measured tropospheric ¹⁴C concentrations are integrated into the bomb peak curve, the time of birth and death of an individual can be estimated by comparing the radiocarbon content of a skeletal sample to the bomb-curve value. In July 2017, about 1,000 skeletal remains were excavated at the construction site of Sokcho. For medico-legal purposes, we conducted anthropological and odontological examinations of all the human remains. We then conducted the radiocarbon analysis on seven femora (head and body portions), five mandibular teeth, and soil from the site through a request to the Korea Institute of Geoscience and Mineral Resources. The results demonstrated that the estimated year of birth or death was prior to the 1950s. Due to the diverse distribution of results, we deduced that the human remains were from the local mass grave. This study supports and suggests the use of radiocarbon dating more frequently in the analysis of human skeletal remains.

In this paper, the hydrogeology of Ardabil plain has been investigated. The hydrogeologic properties of the study area were investigated based on geophysical, geological, water level and pumping test data, Also 65 wells were sampled and analyzed for hydrochemical investigation. Physical and chemical characteristics of groundwater such as temperature, EC, pH, TDS, Na[+], K[+], Mg[2+]+, C[2+]+ HCO[-3]-, SO[4][-2], Cl[-] and CO[3][2-] were determined. Hydrochemical studies indicated that geological units have the greatest effect on the groundwater quality in this plain. According to the results obtained, the Ardabil plain has two aquifers, which one of them is located on top of the other. The upper aquifer is multi-layer with varying thickness [20 to 40 m] across the plain and is extracted for different kind of water supply. The number of penetrating wells to the lower aquifer is very low and may not be extracted because of its poor water quality. General direction of groundwater flow is from other directions to the north-west of the plain. The estimated hydraulic parameters of transmissivity and specific yield varies spatially from 50 to 2200 [nr/day] and 0/021 to 0.14, respectively

Pesquisa sobre confiabilidade de notícias a respeito do 'aquecimento global', em veículos do grupo de comunicação UOL, Folha.com e Folha de S. Paulo, revelou certa polaridade de posições entre a concordância plena de que as causas sejam exclusivamente antrópicas (posição predominante) e sua completa negação. A amostra compreende 676 notícias, entre mais de três mil relacionadas ao tema, entre outubro de 2007 e outubro de 2008. Avaliou-se a hipótese de ser o noticiário dos três meios de comunicação dominado pelas posições do Painel Intergovernamental de Mudança Climática. Em termos absolutos, o Painel é a fonte mais referenciada, pois apenas sete notícias constituem exceções ao 'consenso'. Tais opiniões contrárias perfazem 1,03% da amostra.
Research into the reliability of news reports on 'global warming' published by the UOL media group, Folha.com and Folha de S. Paulo reveals a tendency for positions to be polarized between complete agreement with the assertion that the causes are entirely anthropogenic (the dominant position) and complete denial. The sample comprised 676 news items from more than 3,000 published on the topic between October 2007 and October 2008. The study tested the hypothesis that the news output of the three media outlets is dominated by the positions of the Intergovernmental Panel on Climate Change. In absolute terms, the panel is the most frequently cited source, since just seven news items comprised exceptions to the 'consensus.' These contrary opinions made up 1.03% of the sample.

Discute a formação dos conceitos de natureza, espaço e morfologia na obra de Alexander von Humboldt e seus impactos na formação da geografia física moderna. Influenciado pelas reflexões de Kant em Crítica do juízo e pelos trabalhos de Goethe e Schelling, Humboldt desenvolveu nova interpretação e representação para a natureza na superfície da Terra, em que o conceito de espacialidade é fundamental para a explicação dos fenômenos da natureza. A geografia física moderna estrutura-se a partir de complexo cruzamento de influências estéticas e instrumentais desenvolvidas por Humboldt, nas quais o princípio da conexão é importante para a invenção artística e científica do conceito de paisagem geográfica.
The article discusses how Alexander von Humboldt developed the concepts of nature, space, and morphology in his works and impacted the shaping of modern physical geography. Influenced by Kant's ideas in Critique of judgment and also by the writings of Goethe and Schelling, Humboldt devised a new interpretation and representation of nature on Earth's surface, wherein the concept of space is essential to explaining natural phenomena. Modern physical geography is grounded in a complex interweaving of aesthetic and instrumental influences fashioned by Humboldt, with the principle of connection playing an important role in the artistic and scientific development of the notion of a geographic landscape.

Ultraviolet [UV] radiation affects human organs such as skin, eyes and immune system, as well as animals and plants. The main natural source of UV radiation is the Sun. To study the effects of solar UV radiation there is a need to quantify variations of solar energy received on the earth surface at different intervals. To measure UV radiation a broadband fiber optic UV spectrometer was used. With the spectrometer, the energy received at earth surface was measured from wavelength 100 to 400 nm [the UV spectrum]. Measurement duration was from January first to the end of December 2003, and from sunrise to sunset. The received UVC at the ground level was too low to be measured. The measured UVA was between 11 to 21 times higher than UVB energy during the measurement period. The minimum UV received on the ground level was in January and it was 14.5x10[5] J/m[2] while the maximum was in July and it was 80.14x10[5] J/m[2]. Total UV radiation received on the ground level was during the year of measurement period 579 x10[5] J/m[2]. The measurement showed that UVC intensity on the earth surface was negligible. As the wavelength increased the receiving UV energy at the ground level also increased. From the results, it has become clear that the main health consequences of solar UV were related to UVA band. As the intensity of the UVR during summer is too high, a method of UV health risk reduction should be devised

El objetivo de este trabajo fue la cuantificación tempo-espacial de cambios en la posición de la línea de costa, en el sector de la laguna de Unare, Estado Anzoategui. Se realizaron mediciones fotogramétricas, usando la cobertura aerofotográfica de distintos años del Instituto Geográfico de Venezuela "Simón Bolívar", correspondientes a las exposiciones 2293A de la misión de enero del año 1961. a escala 1:50.000 y las fotografías 037, 111, 040 y 042 de la misión 0401161, a escala 1:10.000, del año 1980. Debido a la dificultad para localizar con precisión en el área a medir (cordón litoral de la laguna de Unare) los mismos puntos en misiones tan diferentes, se utilizó un método geométrico. Los resultados indican que existe un retroceso de la línea de costa de 150 metros aproximadamente, entre 1961 y 1980, lo cual puede considerarse como un efecto combinado de factores y elementos naturales y antrópicos de carácter regional y/o local, introduciendo serias modificaciones en el balance sedimentario. Esto genera erosión de las playas, con evidente retroceso de la línea costera y afectación de la infraestructura existente por socavación de sus bases, trayendo pérdidas económicas a los habitantes y organismos que operan en el área. Se recomienda promover investigaciones detalladas de estos problemas, con la finalidad de conocer a fondo la situación y establecer normas y medidas de ocupación y manejo del espacio, tendientes a mitigar y prevenir el impacto de la erosión costera sobre la región y sus habitantes.
