Exploration is the risky part in the mining business stage. The final goal of exploration is to discover an economic deposit in the certain area; generally by using the three main stages of exploration which are to find, to prove and then to evaluate the presence of minerals deposit. All the three tasks are required the exploration database which is commonly consisting of spatial information of raster, vector and point data. The different type of data is required different data handling as well as data storage system. To reduce the risk, exploration should be done phase by phase. Commonly every single phase of exploration have different propose, method and data collected. Understanding of the exploration business processes, activities and what kind of the data collected and/or required for every stage is important to design and improve the database system itself. In addition, the growing of information technology and computers science, and the increase of data exploration itself; the exploration evaluation will rely more on digital data processing. Database management and quality assurance awareness is critical to build the solid and correct exploration information for further analysis and evaluation of every exploration stages. The database is the primary input to create decision for further exploration stages.

Nanocrystalline CaCu3Ti4-xVxO12 (x =0, 0.025, and 0.05) powders with particle sizes of 100-200nm were successfully synthesized using a poly(ethylene glycol) solution. All the ceramic samples exhibited the pure CaCu3Ti4OL12 phase. The grain size of CaCu3Ti4-xVxO12 ceramics increased slightly as V doping ion concentration increased;whereas, the dielectric permittivity of the ceramics decreased slightly. The nonlinear current-voltage properties of CaCu3Ti4OL12 ceramics were improved significantly by substitution of V ions. Impedance spectroscopy analysis and investigation of non-ohmic electrical properties revealed that the electrical resistance of the grain boundary and breakdown electric field strength were markedly increased by substitution of V ions;whereas, electrostatic potential barrier height at grain boundaries decreased slightly. © 2013 The Japan Society of Applied Physics.

The paper presents a method to determine a position of objects in three dimentional coordinates. The proposed method uses a vision-based localization using two low cost cameras. The formulation is derived by using a pin-hole camera principal to project a location of a point in a 2D image into 3D space. This method can be used for indoor unmanned aerial vehicles localization to provide position information for control and navigation purposes.

Procedia Earth and Planetary Science 2013年 6卷 212-218页

Mercury analysis from soil survey is one of the standard methods in geothermal exploration surveys conducted by Center for Survey and Geological Data or PSDG (formerly DIM). The objective of this paper is to analyze thresholds of four non volcanic geothermal systems in Sulawesi, i.e. Suwawa, Marana, Pincara and Mangolo. The value of Hg (ppb) is differ from one prospect to another. Its value ranges from tens ppb up to few thou sands ppb, depends on the geology and geothermal system; in high temperature volcanic geothermal system, or in non-volcanic geothermal system. Therefore determination of threshold that separate background and anomaly is important for better delineation of Hg anomaly area. Prior to threshold determination, a probability plot is used to examine the normality and the existence of sub population within the data. Sub population located at the end left of probability graph or sub population with the lowest range value is assumed containing the background and threshold information. The threshold is then calculated using mean plus one standard deviation of data within this sub population. Comparison of the calculated number with the published threshold value shows very significant difference in term of anomaly area coverage for further exploration target. This paper demonstrates Exploratory Data Analysis (EDA) techniques that can be applied as a tool to determine threshold value. The results suggest that this statistical methodis able to assist and support a better threshold value determination.

Subcutaneous Preadipocytes Are Ideal Candidate To Produce A Large Number Of Functional Platelets In a Culture System

Platelet transfusions are widely used for patients with severe thrombocytopenia. There are, however, practical problems in the current donor-dependent platelet transfusions, such as the limited supply and risk of serious immune reactions. Thus, the development of new strategies for generating platelets for transfusion is crucial. Platelets have been differentiated from hematopoietic stem cells, fetal liver cells, embryonic stem cells, induced pluripotent stem cells, NF-E2-transduced fibroblasts, and preadipocytes. Here, among these cells preadipocytes, especially in the subcutaneous adipose tissue, could be ideal candidate cells for manufacturing megakaryocytes (MKs) and platelets, because (1) they are relatively easy to obtain large quantities and have ability to proliferate in vitro, (2) their differentiation does not require gene transfer, as they possess genes in relation to megakaryopoiesis and thrombopoiesis, such as p45NF-E2 and c-mpl, and (3) they differentiate into MKs and platelets using an endogenous thrombopoietin. Thus, to clarify the usefulness of preadipocytes as a donor-independent source for platelet transfusion, we compared both number and function between platelets derived from mouse subcutaneous preadipocytes and those from bone marrow mononuclear cells (BMMNCs), the established cell source for manufacturing platelets. First, BMMNCs were not feasible for their expansion in vitro and therefore the cells were directly seeded in MK lineage induction media. In contrast, preadipocytes were to be passaged 6 times without any morphological changes, and then cultured in MK lineage induction media for their differentiation into platelets. Thus, as assessed by CD41-positive platelet-sized cells, 106.2±5.0 ×105 or 3.9±1.0 ×105 platelets were obtained from 106 preadipocytes or 106 BMMNCs, respectively (p<0.01). To next analyze platelet function, the binding of Alexa Fluor 488-labaled fibrinogen to CD41-positive platelet-sized cells, as assessed by mean fluor

Determination of earthquake hypocenter in Indonesia conducted by the Meteorological, Climatological, and Geophysical Agency (MCGA) has still used a 1-D seismic velocity model. In this research, we have applied a Fast Grid Search (FGM) method and a 3-D velocity model resulting from tomographic imaging to relocate earthquakes in the Sumatran region. The data were taken from the MCGA data catalog from 2009 to 2011 comprising of subduction zone and on land fault earthquakes with magnitude greater than 4 Mw. Our preliminary results show some significant changes in the depths of the relocated earthquakes which are in general deeper than the depths of hypocenters from the MCGA data catalog. The residual times resulting from the relocation process are smaller than those prior to the relocation. Encouraged by these results, we will continue to conduct hypocenter relocation for all events from the MCGA data catalog periodically in order to produce a new data catalog with good quality. We hope that the new data catalog will be useful for further studies.

Procedia - Social and Behavioral Sciences 2012年 36卷 112-122页

作者： Anindrya Nastiti Indrawan Prabaharyaka Dwina Roosmini Tresna Dermawan Kunaefi Study Program of Environmental Engineering Faculty of Civil and Environmental Engineering Institut Teknologi Bandung Jalan Ganeca 10 Bandung 40132 Indonesia

Marginalized urban migrants thrive in informal economy, where health and safety are often neglected. Findings on previous studies have listed several informal characteristics; occupational injuries and diseases in informal setting; and components of health expenditure. This paper attempts to assess health-associated cost in informal industry through questionnaire containing basic information of respondent and household members, economic and occupational assessment. Different types of jobs surveyed, target population, biases from occupational/non-occupational cost and household/individual expenditure, and validation method are challenges that must be addressed. This paper serves as policy-tool reference to improve the well-being of informal workers by improving nationwide workforce survey.
