Biostratigraphic constraints for a Lutetian age of the Harrersdorf Unit (Rhenodanubian Zone): Implication for basement structure of the northern Vienna Basin (Austria)
Authors: Kranner Matthias , Harzhauser Mathias , Rögl Fred , Ćorić Stjepan , Strauss Philipp 
Published: November 2019

Abstract
The formations underlying the Neogene infill of the Vienna Basin are still poorly documented. Until now correlation of subsurface lithostratigraphic units with those of the Rhenodanubian nappe system and the Magura nappe system, outcropping at the basin margins, has been based on extrapolations. A recent drilling campaign in the Bernhardsthal oil field of the northern Vienna Basin in Austria reached the pre-Neogene basement and provided cuttings for biostratigraphic and paleoecological analyses. Based on these data, acquired by using detailed micro- and nanno-paleontological analyses, a Lutetian age (middle Eocene) and a bathyal depositional environment for the Flysch of the Harrersdorf Unit was documented. The lithological similarity of the drilling with the Steinberg Flysch Formation of the Greifenstein Nappe and its Lutetian age suggests, that the middle Eocene part of the Harrersdorf Unit represents a continuation of the Greifenstein Nappe of the Rhenodanubian Flysch, rather than a frontal part of the Rača Nappe of the Magura Flysch as previously thought.
Examples of vibratory crushers applications in crushing technological lines
Authors: Mazur Marcin 
Published: November 2019

Abstract
Very fine crushing of hard and very hard materials, to product of particle size less than 2-4 mm at feed particle size of 50-200 mm, requires a very large energy inputs. This is mainly because of the need for at least three or even four degrees of crushing, containing: jaw, cone or impact crushers. One of the methods of reducing the amount of energy expended on the crushing process is reducing the number of crushers in technological line. By replacing a large number of less effective crushers with fewer machines but characterized by higher crushing efficiency we can gain considerable savings in investment and operating costs. This is possible by using crushers capable of obtaining much greater degrees of fragmentation than the aforementioned, that is vibratory crushers. The paper includes the systematic of currently used vibratory crushers, their mechanical diagrams, descriptions of the construction and operation, and basic technical parameters as well as examples of crushing technological lines utilizing vibratory crushers.
Modern grinding balls sorting machines
Authors: Piekaj Paweł 
Published: November 2019

Abstract
Raw materials produced in large quantities are ground in ball, vibratory and stirred ball mills. In mills, the working parts are grinding balls. During grinding, grinding balls wear, change their diameter and lose their shape. The effect of this is the unfavourable change in the grinding balls parameters, which results in deterioration of the technological conditions of the milling process. Relevant parameters of the grinding balls set are restored during maintenance shutdowns. Grinding balls are sorted into appropriate size classes; grinding balls that are not suitable for further use are rejected, and then a set of grinding balls with appropriate parameters is used again. The time needed to prepare the required set depends mainly on the sorting time. To reduce this time, appropriate grinding balls sorting machines are used. The paper presents major problems associated with the grinding balls sorting process, a comparison of modern types of grinding balls sorting machines, a description of their construction and technological parameters.

Published: November 2019

Abstract
This article attempts to solve the problem of load compensation in mesh planetary gearing, with the innovative design idea, resulting from the increased plasticity of the planet wheels (satellite). The cognitive main objective of the experimental work was carried out to identify the comparative effect of the split narrow planet gears, on the load distribution on the length of the teeth of the planet gears of the central wheel of the planetary gear. Achieving this aim, in addition to in-depth analysis, requires experimental research on a specially-built test stand and simulation tests on a solid model of the transmission using the finite element method (FEA). This article presents the concept of a novel test stand, design methodology and research on the influence of the sectional satellite wheels on the load mesh of planetary gears in mining machines.
Determination of crushing energy during vibratory crushing
Authors: Mazur Marcin 
Published: November 2019

Abstract
The paper presents a new method of determining the energy consumption for vibratory crushing. Using the laboratory vibratory jaw crusher with kinematic actuation of the jaws, the study of determining power consumption while crushing limestone and diabase was conducted. During the study, electrical energy used on the crushing process was measured as a function of changing design and kinematic parameters of the vibratory crusher, i.e.: jaws stroke, the outlet gap size and frequency of jaws vibration. The article presents program of the research, the laboratory test stand of the vibratory jaw crusher KW 40/1 and the test results. Comparing the theoretical crushing energy requirements, determined by the Bond hypothesis, with the values measured during tests a large differences were observed. Using the Bond hypothesis the Vibratory Work Indexes were determined for the tested materials. Their values are higher than limestone and diabase Work Indexes available in the known literatures. The explanation may be greater amount of energy transferred to the material during vibratory crushing, which results in much higher efficiency of the crushing process.
Small-scale testing of coal dust explosion propagation and relation to active barrier suppression systems
Authors: Johnson Catherine , Rutter Barbara , Urban Christopher , Schott Joseph , Doucet David , Moore Chance , Perry Kyle 
Published: November 2019

Abstract
Coal dust explosions are a lethal threat to anyone working in an underground coal mine. Many coal mining countries including Australia and much of Europe already utilize passive barrier explosion suppressant systems but due to differences in ventilation patterns in the United States, simple passive systems such as the bagged barrier are not as cost effective. Active systems are triggered by properties of an explosion, such as pressure, heat, or light, and release or project a suppressant into the environment to suppress an explosion. To deploy an active system, the best sensor and suppressant release location and spacing must be determined; this must account for total system latency and explosive propagation speed. A 10:1 model of a longwall entry system has been developed to study the pressure wave propagation of coal dust explosions and consequent triggering of different suppressants. The scaled model, with its removable stoppings, allows multiple potential propagation pathways for an explosion to be repeatedly tested, different from typical straight shock tunnel tests. The layout also facilitates the placement of sensors and cameras to fully observe and document the tests. The pressure wave characteristics found at crosscuts and corners will aid in the development of active barrier trigger systems and spacing of suppressant release locations.

Performance evaluation of continuous miner based underground mine operation system: An OEE based approach
Authors: Banerjee Sumit 
Published: November 2019

Abstract
CM is a globally renowned machine, designed to work as a mass production technology for underground coal. Different major coal producers across the globe are using this technology for decades to produce underground coal efficiently. India is also one of the major players globally in the arena of coal production and adopted this cutting edge technology since last decade by implementing at. few of the selective underground coal mining projects. Performance of CM technology is influenced by the geo-mining condition, fleets of other ancillary units and reliability of subsystems while implementation of this system depends largely on the extent of reserve. These aspects generate a scope of large scale research and development in this field. Overall Equipment Effectiveness (OEE) is the parameter to benchmark the equipment performance globally. OEE is the product of equipment availability, performance and product quality. This mining machine based paper focuses on the Overall Equipment Effectiveness (OEE) of the complete CM based operation to identify the vulnerable systems, which helps to design proper preventive maintenance programme. The CM based system is divided into few subsystems, such as; electrical, cutter, gathering arrangement, traction, hydraulic, chassis, feeder breaker, shuttle car, CM conveyor and out-bye conveyor. The downtime data used for this analysis is collected from an underground coal mine situated in the central part of India, belongs to one leading coal producing company of the country. From analysis it was found that, electrical systems and conveyors are among most vulnerable systems and deserves more care during maintenance. On the basis of these results recommendations are made to redesign the Preventive Maintenance Programme, in order to avoid the lower availability as well as lower OEE.

Rodolfo Llinás, el neurocientífico colombiano que ejerce como director del Departamento de Fisiología y Neurociencia en la Universidad de Nueva York, insiste en que “a la gente hay que enseñarle a pensar”. Llinás defiende ante todo la preeminencia del pensamiento, la exalta y aboga por ella en sus múltiples entrevistas, como en la de El Tiempo el 22 de febrero del 2011 en la que habla acerca del vínculo entre la educación y la producción científica del país. Dice: “Hay que tener no solo conocimiento y equipos; también gente a la que se le deje inventar, a la que se le deje pensar […] Hay que en- señarle a la gente a pensar y a que invente sus propias soluciones”.

Ainda hoje no Brasil a maior fonte de produção de pesquisa é a universidade, sendo, portanto, fonte contínua de inovações. Entretanto ao levarmos em consideração a relação existente entre o mercado e as mudanças tecnológicas, observa-se que o processo de inovação, que permeia esta troca, não evolui apenas no sentido ciência-mercado, já que o oposto também acontece. Os avanços da ciência quanto às necessidades da sociedade alimentam o processo produtivo enquanto que estas últimas propiciam as inovações (Lemos, 2000).A interação universidade-empresa vem ganhando espaço em nossos tempos, ainda que haja diferenças nas funções de cada uma. Enquanto a missão fundamental da universidade é a formação de pessoal qualificado, o papel da empresa é gerar produção e riqueza. Nessa interação profícua todos saem ganhando: a universidade é estimulada a melhor contribuir para a formação de seus alunos enquanto que a empresa é instigada a valorizar o conhecimento (Cruz, 2000).Nesta perspectiva, estamos realizando o IV Seminário de Pesquisa e Desenvolvimento (P&D) e I Encontro e Iniciação Científica PIBIC/CNPq. A publicação dos trabalhos apresentados neste evento representa um marco na pesquisa que acontece nesta Instituição. Agradecemos ao CNPq e ao ISECENSA pelo apoio aos projetos de iniciação científica.

Using Newspapers as Learning Media to Teach Reading Skills
Authors: Rahmasari Brigitta Septarini 
Published: November 2019

For teachers the newspaper offers a special attraction. It has been called the living textbook and it lives up to that name. The newspaper can be used to enhance skills in reading. Critical thinking is the natural outgrowth of using a newspaper to learn. Unlike textbooks, which are several years outdated by the time they get into students' hands, the newspaper comes alive with information. The newspaper expands the curriculum with an unlimited amount of information to use as background for learning activities. These activities will help students improve their reading skills. These skills are how to find the main idea, how to increase vocabulary, how to find detail, how to make inference and how to find reference. They will employ many critical thinking skills as they are required to interact with the authentic material found in the newspaper.
