Mapping activities for the implementation of basic and executive projects for electric power transmission lines systematically involves topographic surveys. This study presents the results of a comparative study on the influence of the density of aerial survey points, LiDAR (Light Detection and Ranging), for the calculation of digital terrain models (DTMs) in typical areas of the northeastern region of Brazil, in the context of modeling ground for planning electricity transmission lines. The study area is the region covered by the 230 kV Ibicoara/Brumado transmission line, located in the state of Bahia/Brazil.. In part of this region, elevations of the mountains of the Western Edge of Chapada Diamantina predominate. Therefore, points with varying densities were used to interpolate DTMs in different environments. Point cloud classification (Airborne LiDAR) was performed using the TerraScan program using semi-automatic classification methods, followed by manual refinements. To evaluate the terrain models obtained with different point densities, four areas were selected under transmission line: Area 1 (24.4/m2), Area 2 (46.0/m2), Area 3 (33.7/m2) e Area 4 (29.7/m2). The Airborne LiDAR survey was performed with an Optech ALTM Pegasus HD500 sensor, calibrated to obtain a density of 15 points/m2. The results showed that, depending on the nature of the vegetation cover, less dense laser surveys do not offer enough quality to generate DTMs. However, in some cases, when the vegetation is denser and the terrain is not flat, the quality of the DTM decreases as the density of the points decreases. The study shows that the survey density must be suitable for the region to be analyzed. An important guideline would be to repeat this study in other areas with different coverage and relief variations, in order to create specifications to serve as a basis for planning LiDAR surveys on other transmission lines.

Geological modeling is the primary task of any exploratory geological investigation, and it is performed even during the mine development. In the study area, the Serra dos Quintos Formation hosts banded iron formations represented by assorted itabirites. The database used in this work was exploited from a geological databank which was structured to gather data and information depicted from an exhaustive exploratory drilling program. A survey was performed throughout the entire databank to collect the available thickness data values (measured in meters) from drill core logs that intersected the itabirite. Since structural heterogeneities can occur within these rocks, this study aims to identify such features. Geostatistical estimation and simulation methods were employed to map folded itabiritic beds based on thickness data accurately. Kriging estimators are often used for practical reasons; however, sometimes, the estimates can be smoothed and do not represent the entire original data range. Simulation algorithms can yield several stochastic images, but local accuracy cannot always be guaranteed. Simulated annealing was performed by adjusting the global statistics and preserving the local accuracy. We demonstrated that the banded iron formations’ thicker areas might correspond to the antiform fold as the dominant tectonic feature in the study area. Finally, we show that the simulated thickness map discloses the thicker mineralized spots. Meanwhile, the thinner ones may unveil intrinsic structural heterogeneities mainly observed at the limbs of the Bonito fold, where intensive deformation within the itabiritic layer was higher than expected. Concerning the mining issues, information obtained from the simulated thickness map could provide ancillary data to improve mining planning in the study area.
地质建模是任何勘探地质调查的首要任务，甚至在矿山开发期间也会进行地质建模。在研究区域内，Serra dos Quintos组含有以各种铁英岩为代表的带状铁地层。本工作中使用的数据库是从地质数据库中开发的，该数据库的结构旨在收集详尽的勘探钻井计划中描述的数据和信息。对整个数据库进行了调查，以收集与铁英岩相交的岩芯日志中的可用厚度数据值（以米为单位）。由于这些岩石中可能存在结构不均匀性，本研究旨在确定这些特征。采用地统计学估计和模拟方法，根据厚度数据准确绘制了折叠铁英岩床。克里格估计量的使用往往是出于实际原因；然而，有时，估计可以被平滑，并且不代表整个原始数据范围。仿真算法可以产生多个随机图像，但不能总是保证局部精度。通过调整全局统计并保持局部精度来执行模拟退火。我们证明，带状铁构造的较厚区域可能对应于作为研究区域主要构造特征的消弧褶皱。最后，我们表明模拟厚度图揭示了较厚的矿化点。同时，较薄的褶皱可能揭示了主要在Bonito褶皱的边缘观察到的内在结构不均匀性，在Bonito折叠处，铁英岩层内的强烈变形高于预期。关于采矿问题，从模拟厚度图中获得的信息可以提供辅助数据，以改进研究区域的采矿规划。

Studies assessing the presence of endocrine disrupting compounds in marine environments have increased in the last decades. In Brazil, the combination of poor sanitation conditions and low investment in sewage treatment plants leads to significant contamination of receiving waters. The risks of these micropollutants in the aquatic biota include biochemical and histopathological alterations of the liver, gonads, and kidneys, as well as, reproductive process and development modifications, and behavioral changes, among others. The aim of this study was to evaluate the quality of the surface and deep waters of Guanabara Bay, southeastern Brazil, regarding the presence of estrogenic substances. Acute toxicity assays were also conducted employing Vibrio fischeri. The estrogenic activity of the water samples was determined by Yeast Estrogen Screen assay and the quantification of the Bisphenol A, estriol, 17β-estradiol, and 17α-ethinylestradiol by high-performance liquid chromatography, using fluorescence and diode array detectors. Estrogenic activity ranged from 9 to 77 ng L-1 of estradiol equivalents. The highest micropollutants concentrations were detected for bisphenol A (298.5 and 465.5 ng L-1), followed by 17α-ethinylestradiol (248 and 256.9 ng L-1), estriol (70.7 and 179.6 ng L-1), and 17β-estradiol (167 and 174.8 ng L-1) for surface and deep waters, respectively. The findings indicate significant risks for the Guanabara Bay ecosystem. No acute toxicity effects were observed in the V. fisheri assay. These data reflect the current environmental degradation situation of the bay’s waters and highlight the need for the systematic monitoring of this important estuary.
过去几十年来，评估海洋环境中存在的内分泌干扰化合物的研究有所增加。在巴西，恶劣的卫生条件和污水处理厂的低投资导致接收水受到严重污染。这些微污染物对水生生物群的危害包括肝脏、性腺和肾脏的生化和组织病理学改变，以及生殖过程和发育改变以及行为改变等。本研究的目的是评估巴西东南部瓜纳巴拉湾表层和深层水域中雌激素物质的质量。采用费氏弧菌进行急性毒性试验。采用酵母雌激素筛选法测定水样的雌激素活性，采用荧光和二极管阵列检测器，高效液相色谱法定量测定双酚A、雌三醇、17β-雌二醇和17α-炔雌醇。雌激素活性范围从9至77 ng L-1的雌二醇当量。微量污染物浓度最高的是双酚A(298.5和465.5 ng L-1)，其次是17α-炔雌醇(248和256.9 ng L-1)、雌三醇(70.7和179.6 ng L-1)和17β-雌二醇(167和174.8 ng L-1)。研究结果表明，瓜纳巴拉湾生态系统面临重大风险。在鱼弧菌试验中未观察到急性毒性作用。这些数据反映了海湾水域目前的环境退化情况，并突出了对这一重要河口进行系统监测的必要性。

The implementation of organic farming programs in Indonesia involves various actors and various interests in it. The relationship between actors and their interests has positioned organic agriculture at the intersection between modern agricultural camouflage and the antithesis of modern agriculture (postmodern agriculture). How did this happen? so this research is very important to provide a complete picture in describing the involvement of actors and power relations as one of the key factors that will determine theformulation of policies for developing organic agriculture in the future. This research used a qualitative method with a case study approach. Data collection techniques were carried out by in-depth interviews, observations, and document studies. The research data were analyzed concerning the Miles and Huberman (2002) framework, which consisted of stages of data reduction, analysis formulation, and concluding. The results showed that there were four typologies of actors, namely, type A actors oriented to spiritual values; actor type B oriented to moral values; type C actor is oriented to rational values and type D actor is oriented to political/powervalues. The struggle between actors is dominated by driving actors (advanced farmers or champions, state apparatus, capitalists) who have stronger knowledge power. The rhetoric and images narrated by the driving actors then become tools for domination to seize the rights of other actors with the interests and powers attached to each actor. The implementation of organic agriculture which is full of power interests puts organic farming programs in Indonesia trapped in a market trap and a poor meaning reduction of moral values, human values, spiritual values, and ecological values.
