The Transfer of Railway Technologies and Afro-Asian Labor Processes within the British Empire
Authors: Kerr Ian J. 
Published: October 2018

Abstract
The transfer of railway technology within the British Empire, and particularly to India provides the focus for this paper that explores—conceptually, historiographically and substantively—what was transferred and how that transfer took place. Drawing upon the large-scale technical system literature and labor history the paper highlights various kinds and levels of transfer agents working through, albeit in an often-contested fashion, Afro-Asian labor processes as central components within the transfer process when railway construction was involved. Railway construction is then counterpoised to railway operation where the transfer process exhibited greater British dictation and adherence to British practice.
Colonial Railways and Conflict Resolution Between Portugal and the United Kingdom in Africa (c. 1880–early 1900s)
Authors: Pereira Hugo Silveira 
Published: October 2018

Abstract
In the 1870s, Portugal transferred the public works program it was undertaking on the mainland – in which railways played a decisive role – to its African colonies of Angola and Mozambique. In this strategy, the United Kingdom was an obvious partner, given the historical connection between both nations and the geographical proximity between the colonies each country had in Africa. However, British and Portuguese imperial agendas could easily clash, as both London and Lisbon coveted the same areas of Africa. Hence, the initial and apparent cooperation rapidly evolved to a situation of conflict. In this paper, I aim to analyse three instances of dispute between Portugal and Britain about colonial railways in Angola and Mozambique. I will use the methodological tools of conflict resolution analysis in a historical perspective and the concept of track-two diplomacy within the framework of technodiplomacy.
The Transport Revolution on Land and Sea: Farming, Fishing, and Railways in Great Britain, 1840-1914
Authors: Schwartz Robert M. 
Published: October 2018

Abstract
The introduction and expansion of rapid rail transportation in Great Britain helped transform sea fishing and make fresh fish a new commodity of mass consumption. In agriculture the rail network greatly facilitated the shift from mixed cereal farming to dairy farming. To demonstrate the timing and extent of these changes in food production this article blends history and geography to create a spatial history of the subject. Using the computational tools of GIS and text mining, spatial history charts the expanding geography and size of the fresh fish industry and documents the growing concern among fishermen of over-fishing. In agricultural, huge flows of cheap wheat from the United states caused a crisis in British wheat farming, forcing many farmers to convert arable land to pasture for use in dairy farming. Given the growing demand for fresh milk in cities and increased availability of rapid rail transport in rural areas, dairy farming replaced wheat farming in outlying counties such as Wiltshire, the example examined here.

Spreading of Cracks Due to Thermal Fatigue in Metal Molds
Authors: Ružbarský Juraj , Biały Witold 
Published: October 2018

Abstract
The article deals with the formation and spread of cracks from thermal fatigue in metallic forms. For a detailed examination of the problem, it is necessary to describe the thermal side of the process and the mechanism of mechanical stressing of the material. For the heating of the material is valid where the thermal diffusivity of the material is exercised by the decision method. The stress of the material by heating from the die casting metal depends mainly on the physical properties of the material when the calculated stress does not exceed the yield point. Also, with the help of dislocations write the life to the origin of the cracks in the cycles eventually the share of this lifetime on the total lifetime in dependence on the mechanical and physical properties of the material. During operation tests the occurrence of the cracks on the mold surface was initiated by the inclusion or concentration of stress in the knurling effect of fine grooves after grinding. Other cracks occurred in the undersurface layer and their direction was statistically accidental.

Analysis of Corners Milling of Aluminum Alloy Elements
Authors: Anasiewicz Kamil , Włodarczyk Maciej 
Published: October 2018

Abstract
The article presents comparative research on the effects of milling of concave corners of elements made of aluminum alloy 7075. The work focuses on the study of the impact of changes in technological parameters and types of machining on the obtained geometrical state of the machined samples. Correct milling of the corners requires selection of the appropriate feed rate and the proper engagement angle of the milling cutter. At the corners, tool engagement angle increases, which significantly hinders the execution of stable machining and adversely affects the geometric and qualitative characteristics of the surface in the corners. Study with application of various strategies and technological parameters of milling corners with variable opening angles were carried out. The main parameters of surface roughness of the machined elements were examined. When analyzing the results obtained, conclusions were formulated indicating the relationship between the change of selected technological parameters, with the assumed type of treatment, and the obtained quality parameters of the samples made.

Design and Modeling of an Experimental Hydraulic Device
Authors: Tkáč Zdenko , Halenár Marek , Kosiba Ján 
Published: October 2018

Abstract
The design of the experimental laboratory device is based on the construction of the hydraulic circuits of mobile devices. It is possible to ensure the repeatability of the flow characteristic measurements at the laboratory. This means that in the operating test it is possible to verify the flow characteristics of the hydraulic pump and these results are not affected by the change in the physical properties of the applied liquid. By comparing of the flow characteristics directly on the work equipment (mini-excavator, etc.), the disadvantage is the need for dismantling the hydraulic pump and its mounting on the laboratory device. In some working device removal is not possible, where dismantling is structurally difficult or is time consuming, which increases the cost of their operation.The proposed experimental laboratory device serves to verify the flow characteristics of the hydraulic pump and is also designed to be universal, to test external gear hydraulic pump and hydraulic pump with inclined plate.

Published: October 2018

Abstract
Aerosol products are present in different industries including cosmetic, technical, household and many more. These products are subject to number of controls both at the pre-production, in-process and post-production stages. Controls at the pre-production stage relate to checking the conformity of individual components that make up the aerosol packaging, as well as raw materials that are used to create the formula. The checks carried out during the production process are mainly focused on the verification of parameters at particular stages of production. Whereas, post-production checks are related to the evaluation of the finished product. Due to the highest share of metal packaging in the aerosol products market, such products are the subject of this article.

Published: October 2018

Abstract
In engineering industry the production of components begins with separation of the base material and this technological operation can be time consuming, especially in large-scale production. Such production can be made more efficient by means of laser technology focusing on material cutting. Efficiency of cutting is determined not only by shortening of working time or energy saving, but also by the required cutting quality. In the paper we compare the impact of cutting speed changing and laser beam performance on the cutting edge quality. Based on requirements of dimensional accuracy and preset roughness of the cutting edge, we evaluated the cutting quality of laser in samples of different materials. Measured values of sample dimensions and roughness are compared in conclusions of the paper, where we estimate whether the samples meet specified requirements of dimensional accuracy and roughness of the cutting edge in order to make the production process more efficient.
Analysis of the Impact of Unscheduled Downtimes on their Availability in Machine Operations
Authors: Brodny Jarosław 
Published: October 2018

Abstract
Unscheduled downtimes in machine operation are one of the main reasons behind their low availability. Such downtimes are caused by miscellaneous factors and remain difficult to identify in a number of cases. This particularly refers to enterprises that conduct their activities in changing external conditions, such as hard coal mines, where exploitation is carried out in extremely complicated, changeable and dangerous conditions. The process of coal production makes use of various machines that must be adapted to these conditions. The specificity of the working environment makes it necessary for these machines to exhibit high reliability, readiness and efficiency. These features, in turn, make the cost of the machines very high. It is therefore reasonable to make the best use of their capabilities, which translates into the effectiveness of the entire production process. The article concentrates on determining the availability of these machines. It has been assumed that availability is one of the fundamental parameters that define the effective utilisation of machines. The tests were conducted for a longwall shearer as well as an armoured face conveyor and a main haulage conveyor in one of the hard coal mines in Poland. Industrial automation systems were used to determine unscheduled downtimes in the operation of these machines, as well as their time structure and causes. The results obtained indicate that the number of unscheduled downtimes represents a serious problem in mining exploitation.
A Comparative Analysis of the Impact of CNC Miller Programming on Machining Effects
Authors: Kuczmaszewski Józef , Pieśko Paweł , Zawada-Michałowska Magdalena 
Published: October 2018

Abstract
This paper presents a comparison of the impact of the programming methods of a CNC miller on the machining effects. As a part of the study, the test samples were made of the EN AW-2024 aluminium alloy. The CNC machining programs compared were developed with two programming methods: by inputting the CNC machining program directly from the CNC miller's control panel (machine level programming) and in a CAM software environment (CAM programming). The machining effect indicators adopted included: machining time, surface quality, and dimensional deviation of specific geometrical features. A measurement of the machining times revealed than the CAM programming reduced the machining time up to 20% from the machining time of the machine level programming. A conclusion stands valid that CNC machining programs developed in the CAM software environment are more efficient than CNC programming directly with the CNC miller control panel, most likely due to the machining path optimisation in CAM. In addition, given the experimental test results, it was found that smaller machined errors were also obtained for CAM programming. To conclude, the comparative analysis revealed that CAM programming provided better machining results than the machine level programming.

Authors: Szurgacz Dawid , Gondek Horst 
Published: October 2018

Abstract
The article presents the methodology and results of tests of a prototype controller designed for the electrohydraulic control system of a powered roof support. This controller is the basic part of the developed, innovative control system. The tests were carried out on a custom-designed testing station, equipped with one section of a roof support. The aim of the research was to check the functionality and speed of the controller's response while working with the actual support section. The tested controller and the control system has a modular structure, which greatly facilitates its operation and use. Measurements of control functions were carried out on the controller connected to the electrohydraulic control block. The research mainly focused on determining the period starting from the moment of providing the signal to the moment of switching on the basic functions performed by the support section. The obtained results confirm the assumptions made. The controller's operation is very stable, and its response times are very short. It can therefore be assumed that the tested controller is correctly designed and constructed. This creates great possibilities for its practical application in the built-in system for controlling the roof support. This may be particularly important in the case of high-efficiency longwall complexes, for which wireless control of the support is planned to be used. The presented research methodology and obtained results should therefore be an important source of information in the field of testing controllers for powered roof supports.

Abstract
One of the most important aspects related to the proper functioning of prosperous enterprises in the wood industry is to ensure safe and hygienic working conditions. The fulfillment of this condition is obligatory for all workplaces regardless of the field of activity. Due to the specificity of the industry based on wood processing, this industry is inseparably connected with the problem of pollination at workplaces. The chips that are formed during processing make it difficult to work, remain in and around workplaces, creating additional risks and impairing the quality of the manufactured products. It is therefore necessary to apply solutions to eliminate the dust hazard. One of such solutions, belonging to collective protection measures against pollination, are dedusting installations. One of the tools to improve working conditions is mandatory risk assessment. Thanks to its reliable implementation, it is possible to identify hazards occurring at workplaces and take measures to improve working conditions. Proper management of occupational risk is one of the key elements to ensure protection against risks at an appropriate level. The article analyzes the impact of the dedusting installation on the reduction of selected health hazards for employees in the selected carpentry shop.
