25. Food safety challenges associated with traditional foods of Turkey
Abstract Consumer food safety concerns are continually increasing in Turkey, with consumer demand for safer foods becoming an important challenge for the industry. Most traditional foods in Turkey are produced under different requirements, and food safety risk management and risk assessment are conducted primarily by the government. Based on risk assessment

26. A Comparative Study of Cartesian and Delta 3D Printers on Producing PLA Parts
The additive manufacturing processes emerged at the end of the last century and became popular by low-cost 3D printers. The most used printers work on a cartesian configuration, but recently were launched delta machines. These 3D printers use a more complex control system due to their trajectories generation but may present some advantages over the cartesian

27. Study of the Young's Modulus in Microstructures through the Resonance Frequency Technique for Applications in Commercial CMOS Processes
The companies that manufacture devices with techniques inherited from microelectronics, called foundries, generally provide the electrical characteristics of the layers of their manufacturing processes, but they do not provide the mechanical parameters, which prevents the mechanical optimization of any design used in this manufacturing. Thus, the extraction

28. Embrittlement and Corrosion Decay of a Cast Duplex Stainless Steel
Duplex stainless steels (DSS) are Fe-Cr-Ni-Mo alloys, with low carbon content, which have a favorable combination of mechanical properties and corrosion resistance. These characteristics are mainly attributed to a dual phase and refined microstructure, typical of these alloys, consisting of similar amounts of ferrite and austenite. For this reason, DSS are w

29. Multistage Deep Drawing with Ironing of Al-killed AISI 1040 Graded Medium Carbon Steel: a Parametric Study
Analysis of multistage deep drawing with ironing was made while manufacturing of cups from 12 mm thick, 60 mm diameter circular blanks of Al-killed AISI 1040 graded medium carbon steel. Quality requirements of the steel in heat treated condition were examined in terms of tensile properties, formability characteristics, and formability limit diagram. Drawabil

30. Influence of Tungsten on Dry Sliding Wear Behaviour of Sintered/Hot Extruded P/M Alloy Steels (Fe-C-W-Ti)
In the present scenario, Powder Metallurgy (P/M) is an established manufacturing process used to make components of complex geometries with high strength and tolerances by using incredible materials which are difficult to melt or form by other processes. The mechanical properties and microstructures will determine the component characteristic dependent on th

31. Training small producers in Good Manufacturing Practices for the development of goat milk cheese
Abstract Training in Good Manufacturing Practices enhances quality during food processing. This paper evaluates GMP training aimed at improving the chemical, sensory and microbiological quality of goat milk cheese. We worked with 26 families that produce cheese as their main source of income. Semi-structured interviews and observation were conducted to selec

32. Evaluation of Microstructure and Mechanical Properties of Seamless Steel Pipes API 5L Type Obtained by Different Processes of Heat Treatments
This research presents the influence of manufacturing processes and heat treatments on the resulting microstructures and mechanical properties of an API 5L PSL2 seamless steel pipe. Three different conditions are considered - as rolled, normalized and quenched and tempered - to obtain the grades X42R, X42N and X70Q, respectively. Scanning electron microscopy

33. Development and Test of an Equipment to Measure Residual Strain Inside Pipes Using the Hole-Drilling Method
Abstract Residual stresses are present in materials or structural component in the absence of external loads or changes in temperatures. The most common causes of residual stresses being present are the manufacturing or assembling processes. All manufacturing processes, such as casting, welding, machining, moulding, heat treatment, etc, introduces residual s

34. Regional Cluster, Innovation and Export Performance: An Empirical Study
Abstract Regional clusters and innovations in product and processes are found in the literature as important determinants of firms' export performance. However, this relationship is still controversial and very highly constrained by industry, and by regions. Based on a more integrative perspective, the aim of the present article is to investigate the role of

35. 12 mm Thick Circular Blanks of Al-killed AISI 1020 Steel -Applied for Cylindrical Cup Manufacturing by Multistage Deep Drawing with Simultaneous Ironing
Abstract In this paper a new modified processing route has been proposed for producing long cylindrical cups from 12 mm thick circular blanks of AISI 1020 steel (Aluminium (Al) -killed). In this route, flat blanks were made to preformed shape by stamping operation, followed by multistage deep drawing processes(without blank-holder and with inter-stage stress

36. Flexural Behavior of Beams Reinforced with Steel Bars Exceeding the Nominal Yield Strength
Abstract If steel manufactures usually comply with the minimum code specifications, the nominal yield strength of rebar can however be significantly exceeded in many countries, depending on the steel manufacturing processes. Such an increase in yield strength can have negative effects on the flexural behavior of beams designed as tension controlled, and redu
