The “Glossary of Terms Used in Geophysical Exploration” published in Geophysics in February 1968 met with some justified criticism because of the emphasis on seismic exploration for oil. The Addendum published in April 1969 attempted to restore balance as far as mineral exploration was concerned. But one major area of geophysics had still been slighted: that of well logging. This present addendum is intended to complete our coverage of geophysical exploration terms.

Nearly all of the well logging devices currently used in the petroleum industry have found some limited application in metallic mineral exploration and mining. However, due to differing problems, the emphasis in the mineral industries has been on those devices regarded as “exotic” or “specialty” by the petroleum industry. These include devices to measure or determine induced polarization, magnetic susceptibility, and, hopefully, nuclear activation and the use of spectral analysis. Problems which the mining industry believes are solvable with well logging methods include bulk assay and recognition of minerals adjacent to and retired from a borehole, delineation of joint and fracture systems, leaching problems which involve porosity, permeability and groundwater movement, bank stability in open pit mines, roof and pillar loading in shaft mines, grindability, and penetration rates in drilling. Devices currently offered by the well logging industry which may be useful for these problems include those capable of measuring electrical properties, natural and induced nuclear radiation, seismic velocities of both compressional and shear modes, temperature, mechanical features of a borehole such as diameter and rugosity, and borehole photography either direct or by television.

O processo de exploração minerária no município de Boquira/BA iniciou-se nos anos 50, quando Chumbo (Pb) e Zinco (Zn) foram lavrados intensamente por 33 (trinta e três) anos, resultando na exaustão das reservas e no consequente abandono da mina que ocorreu devido ao excesso de oferta internacional destes metais aliado aos altos custos operacionais e ao esgotamento das reservas viáveis. Durante o período exploratório da mina a inobservância da legislação voltada à proteção ambiental e respectivas ações de fiscalização gerou impactos ambientais significativos no município. Este artigo teve como objetivo avaliar o processo de exploração mineral no município de Boquira, apresentando aspectos relacionados à exploração de Pb/Zn no município e ao passivo ambiental deixado com o abandono da mineração. Para isso, foram realizadas pesquisa bibliográfica e documental além de pesquisas de campo com o auxílio de ferramentas do Sistema de Informações Geográficas (SIG) e entrevistas junto à população e o poder público local. A atividade mineral no município causou uma série de danos e conflitos ambientais, sendo palco de um dos maiores passivos ambientais do Brasil.Lead Paths in Bahia: History and Prospects for Mineral Exploration in the Municipality of Boquira / BA A B S T R A C TThe mining process in the city of Boquira/BA started in the 1950s, when Lead (Pb) and Zin (Zn) were intensively planted for 33 years, resulting in the exhaustion of reserves and the consequent abandonment of which occurred due to the international oversupply of these metals coupled with high operating costs and the depletion of viable reserves. During the exploratory period of the mine, the non-compliance with environmental protection legislation and respective inspection actions generated significant environmental impacts in the city. The objective of this article was to evaluate the mineral exploration process in the city of Boquira, presenting aspects related to the Pb/Zn exploration in the city and the environmental liabilities left by the abandonment of mining. For this, bibliographical and documentary research were carried out in addition to field researches with the support of tools of the Geographic Information System (GIS) and interviews with the local public ruling. The mineral activity in the city caused a series of damages and environmental conflicts, stage of one of the biggest environmental liabilities of Brazil.Keywords: History of mineral activity; Mineral potential; Environmental impacts of mining.

The production of rubber modified thermoplastics can exceed rates of 30,000 pounds per hour. If a production plant needs to equilibrate or has an upset, that means operating costs and lost revenue. Results of transmission electron microscopy (TEM) can be used for process adjustments to minimize product loss. Conventional TEM, however, is not a rapid turnaround technique. The TEM process was examined, and it was determined that 50% of the time it took to complete a polymer sample was related to film processing, even when using automated equipment. By replacing the conventional film portion of the process with a commercially available system to digitally acquire the TEM image, a production plant can have the same TEM image in the control room within 1.5 hours of sampling.A Hitachi H-600 TEM Operated at 100 kV with a tungsten filament was retrofitted with a SEMICAPS™ image collection and processing workstation and a KODAK MEGAPLUS™ charged coupled device (CCD) camera (Fig. 1). Media Cybernetics Image-Pro Plus software was included, and connections to a Phaser II SDX printer and the network were made. Network printers and other PC and Mac software (e.g. NIH Image) were available. By using digital acquisition and processing, the time it takes to produce a hard copy of a digital image is greatly reduced compared to the time it takes to process film.

Transparency And Accountability

Investigation in various regions in Indonesia found indications of the alleged fraud that result from unccountable use and management of BOS funds. Among the findings, including payments that do not fit the technical guidelines, no accountability report, and the use of funds with unaccountable receipt. In the Regulation of the Minister of Education and Culture of the Republic of No. 161/2014, stated that: BOS is a government program that is basically forfunding the nonpersonnel operating costs of the primary education as the implementer of compulsory education program. The purpose of this study were (1) to analyze the accounting cycle and financial accountability for the use of BOS funds in the 2015, (2) to analyze the compliance of the accounting cycle and financial accountability of the BOS funds, (3) to analyze the transparency and accountability of BOS fund’s reports. The observed elementary school is SDIT X in Depok, West Java. Result shows that they do not fully compliance to the appropriate regulatory technical guidelines. On the other hand, the transparency and accountability issues show that: (1) BOS Management Team, Teachers Council and School’s Committee’s involvement in the BOS fund management, and (2) evaluation and comparison of the final report of prior periods, so that transparency and accountability of the use and management of BOS funds can be improved.

Electricity Costs

In the animal feed industry, steam is used in pellet making machines. In this process, steam from the boiler is distributed to the pellet mill through the pipe. The purpose of this study is to observe the waste of electricity costs of operating a boiler by calculating heat loss in a distribution pipe. The method of assessing heat loss is done by calculating losses caused by heat loss in the boiler distribution. Then make a calculation application model based on the data obtained. From the data analyzed, the amount of heat lost in the non-insulating distribution pipe is 0.766 kJ/s with a loss of Rp 5.628,600 operating costs per month compared to heat loss in an isolated pipe condition of 0.047 kJ/s with losses which cost slightly more than Rp 368 190 / month. This heat loss calculation process is made on an android application by entering the calculation formula on the program and the data that has been obtained.
