Published: October 2017

<p>Para el estudio se estableció como unidades de análisis las comunidades de Cajas Chico, Huamanmarca y Azapampa, considerando que tuvieron procesos urbanísticos comparables que permite comprender estos procesos. Se plantearon los siguientes objetivos: a) Explicar el proceso de urbanización de las comunidades campesinas de Cajas Chico, Huamanmarca y Azapampa. b) Explicar las características de la cultura constructiva de estas poblaciones en el marco del proceso de urbanización que las afecta. Utilizamos el método histórico-analítico y además del método dialéctico que nos permitió ver el proceso evolutivo del crecimiento urbano (construcción de viviendas) en su efecto de servicio y el impacto de la migración. A partir del impacto de la globalización en los medios de comunicación, la difusión y adaptación al contexto de esa información, se puede comprobar a través del estudio que influye en la arquitectura de las comunidades de Cajas Chico, Azapampa y Huamanmarca a través de: su influencia económica, estilos de vida y estética. Estas se materializan a través de la redes de información, conocimiento; transferencias financieras internacionales, medios de comunicación masiva como la televisión, revistas, periódicos, etc. Y que son adaptadas en el contexto receptor. Los pobladores de las comunidades de estudio manifiestan su diversidad constructiva en el material, ornamentación, espacios y funciones de los mismos. Así, a través de la arquitectura de sus construcciones podemos analizar desde el punto de vista de la antropología sus actividades en espacios físicamente delimitados y que expresan significados simbólicos. </p>

Разработаны различные типы наполнителей или усилителей для получения композитных материалов с желательными тепловыми, механическими и электрическими свойствами. Наполнители играют важную переоснащающую роль в повышении эффективности полимеров и эффективности производства. Получены образцы исходного эпоксидного полимера (ЭП) и композитов на основе ЭП и магнетита (Fe3O4), сформированных под действием внешнего магнитного поля и без него. Обнаружено, что формирование композита под действием внешнего магнитного поля приводит к образованию непрерывных каналов из ферромагнитных частиц Fe3O4 в сплошной матрице ЭП. Установлено, что несмотря на высокую собственную электропроводность Fe3O4, наличие вследствие высокого межконтактного сопротивления внутри каналов наполнителя. Теплопроводность в направлении ориентации частиц Fe3O4, существенно возрастает.

<p>Composition and distribution of foraminifers are affected by human activities and have close association with coral reef ecosystem. The aims of this research were to investigate the benthic foraminifers’ composition and distribution in sediment of coral reef ecosystem. Eleven stations of Karang Bongkok, Pramuka, and Onrust Island were observed in this study. The sediments were taken from surface substrate up to 2 cm under the substrate. Samples were washed on sieve with mesh size 0,063 mm, and then dried in oven with 50°C of temperature for two hours. After separating from the sediment, the foraminifers were laid on foraminiferal slide and indentified using binocular microscope. The highest composition of symbiont-bearing foraminiferal assemblages which associated with reef ecosystem was in East Pramuka (78.17%) and the lowest was in South Onrust (21,83%). The opportunistic type had the highest composition in South Onrust (38.67%) and the lowest was in South Karang Bongkok. In west Pramuka had the highest composition of heterotrophic type (57.17%) and the lowest was in North Onrust (11.33%). Onrust Island was dominated by opportunistic type, indicating high nutrient. The highest amount of foraminifers’ taxa was found in Karang Bongkok with good coral reef coverage, while the lowest in Onrust facing with Jakarta Bay.</p> <p>Keywords: composition, distribution, benthic foraminifers, coral reef.</p>

<p>Foraminifera is one of single-celled protozoa, living in the water environment especially marine waters. This organism can be used as bioindicator of environmental conditions of coral reefs through a simple index called FORAM Index. The purpose of this research are to obtain FORAM Index values​, to know any species of benthic foraminifera bioindicator of coral reefs environmental conditions that have been found and to find out whether there is a relationship between FORAM Index to the condition of coral reefs based on coral coverage percentage. The research used survey method on sediment sampling and measurement of environment parameters by P20 LIPI team in April 2011. Several important steps in this research such as sediment samples preparation, sample observation, and sample identification. The results showed that there were 80 species and 31 genera benthic foraminifera bioindicator of coral reefs environmental conditions were found in the Natuna Islands. The condition of coral reefs in the Natuna Islands based on FORAM Index (FI) values ​​ranged from 2.6 to 5.94, and overall there was a positive relationship between FORAM Index and the condition of coral reefs based on coral coverage percentage i.e., the increase of FI was followed by the increase of coral coverage percentage. However, in the terms of correlation there were several different results, there was a strong correlation and a weak correlation.</p> <p>Keywords: foraminifera, FORAM index, coral reef.</p>

Published: October 2017

<p>The purposes of this study were to determine the variability of temperature and its relation to regional processes in the Senunu Bay. The result showed clear vertical stratifications i.e., mixed layer thickness about 39-119 m with isotherm of 27°C, thermocline layer thickness about 83-204 m with isotherm of 14–26°C, and the deeper layer from the thermocline lower limit to the sea bottom with isotherm &lt;13°C. Temperature and the thickness of each layers varied with season in which during the Northwest Monsoon the temperature was warmer and the mixed layer was thicker than those during Southeast Monsoon. During Southeast Monsoon, the thermocline layer rose about 24 m. The 2001, 2006, and 2009 (weak La Nina years), the Indonesia Throughflow (ITF) carried warmer water, deepening thermocline depth and reducing upwelling strength. In 2003 and 2008 thickening of mixed layer occurred in transition season was believed associated with the arrival of Kelvin Wave from the west. In 2002 and 2004 (weak El Nino period,) ITF carries colder water shallowing thermocline depth and enhancing upwelling strength. In 2007 was believed to be related with positive IODM where the sea surface temperature were decreasing due to intensification of southeast wind which induced strong upwelling. The temperature spectral density of mixed layer and thermocline was influenced by annual, semi-annual, intra-annual and inter-annual period fluctuations. The cross-correlation between wind and temperature showed significant value in the annual period.</p><p> </p> <p><strong>Keywords:</strong> temperature, thermocline, variability, ENSO, IODM.</p>

Published: October 2017

<p>Research on the seasonal geostrophic surface current during 2002-2011 in Arafura-Timor waters was conducted using satellite altimetry data. Those data were absolute dynamic topography and absolute geostrophic velocity data taken from Archiving Validation and Interpretation of Satellite Oceanographic data (AVISO). The dynamics of geostrophic surface current varied in every monsoon due to the difference in absolute dynamic topography. During northwest (NW) season, the absolut dynamic topography in Arafura Sea was higher than in Timor Sea by an average difference of 0.1–0.2 m and the geostrophic surface current moved from Arafura Sea toward Timor Sea. During southeast (SE) season, the absolute dynamic topography in Arafura Sea lower than Timor Sea with an average difference of 0.03-0.04 m. In this season, upwelling occurs in Banda Sea and sea surface water in this region becomes lower and the current moved from Arafura Sea to Banda Sea. The absolut dynamic topography difference between Arafura Sea and Timor Sea in NW and SE monsoons was 0.05–0.06 m and so the geostrophic surface current moved from Arafura Sea toward Timor Sea. In Timor Sea, the current moved southwest towards the Indian Ocean. In NW and SE Monsoons the the velocity of surface geostrophic current in Timor Sea (0,3 m/sec) was higher compare in Arafura Sea (0.2 m/sec) due to the configuration of island surround the Timor Sea and its topography.</p><p> </p><p><strong>Keywords: </strong>Geostrophic surface current, altimetrysatellite, Arafura-Timor Sea</p><p> </p>
