Pulmonary Changes

Electron microscopy and energy dispersive x-ray microanalysis (EDXA) are found to be very useful tools for identification of etiologic agents in pneumoconiosis or interstitial pulmonary disorders. Pulmonary interstitial fibrosis and granulomatosis are frequently associated with occupational and environmental pollution. Numerous reports of pneumoconiosis in various occupations such as coal and gold miners are presented in the literature. However, there is no known documented case of pulmonary changes in workers in the sandpaper industry. This study reports a rare case of pulmonary granulomatosis containing deposits from abrasives of sandpaper diagnosed by using EDXA.

Vapor Absorption

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.

Map Integration

This study aim to determine the effect of Problem Based Learning (PBL) models in mind map integration to creativity of problem solving in the environmental pollution concept of graders X. The method used is a Quasi-experimental design form Nonequivalent Control Group Design (pretest- posttest). The study population is all the students of graders X academic year 2017/2018 as many as 9 classes with the number of 360 students. The sample used was 80 students from two classes as an experimental class and a control class. Sampling was done by Cluster Random Sampling technique. Instruments used include test descriptions, questionnaires and teacher observation sheets. The results of the analysis of the test descriptions creativity in problem solving obtained results of hypothesis testing (t test) i.e. 20.5 t count > t table of 2.66 means that Ho refused and Hi accepted, it means PBL learning models in Mind Map integration effect on creativity in problems solving. This is indicated by an increase in the average score on each indicator of creativity in problem solving in which students are able to grow various ideas, enrich ideas, add or detail the details of an idea and determine the truth to solve the problems. From the analysis of questionnaire data showed an interest in learning to use the PBL modela in Mind map integration, students agreed that if the model of PBL in Mind map integration may be easier to learn about the concept of Environmental Pollution. In addition, students also agreed that if the PBL models in Mind map integration effect on creativity in problems solving. The results showed that there was a significant influence between learning using PBL models in Mind map integration those not using the learning models to creativity in problems solving in the concept of environmental pollution of graders X.
