Data-Driven Modeling in Drilling in Well Operations
Swab and surge pressure fluctuations are decisive during drilling for oil. The axial movement of the pipe in the wellbore causes pressure fluctuations in wellbore fluid; these pressure fluctuations can be either positive or negative, corresponding to the direction of the movement of the pipe. For example, if the drill string is lowering down in the borehole, the drop is positive (surge pressure), and if the drill string is pulling out of the hole, the drop is negative (swab pressure). The intensity of these pressure fluctuations depends on the speed of the lowering down (tripping in) or withdrawing the pipe out (tripping out). High tripping speed corresponds to higher pressure fluctuations and can lead to fracturing the well formation. Low tripping speed leads to a slow operation, causing non-productive time, thus increasing the overall well budget.

Exploring Lean HRM Practices in the Aerospace Industry
Lean management is an approach that allows companies to reduce costs and improve quality to achieve significant growth. As such, myriad organizations across many different sectors are deploying resources and effort to implement Lean management principles. However, the adoption of Lean within a company is not straightforward because it is not just a set of tools to be used, but rather a process that requires the active participation and commitment of all the members of the organization, with special emphasis on the employees, as they are the ones doing the actual implementation work. Lean places people at its core, acknowledging their contribution to the company’s growth and the fundamental role human resources management (HRM) practices play in the success and sustainability of Lean transformations. However, the relationship between HRM practices and Lean remains largely unexplored in the literature.

Innovation Management Systems
Standardized innovation management systems (SIMS) are homogeneous management systems which accelerate the conversion of an organization’s innovation strategy into effective actions. Thus, SIMSs ensure that innovation means not mere shiny novel inventions, but rather an organization’s ability to recognize and pursue new areas of opportunity while reacting to fluctuating conditions in its environment. In 2006, the Spanish Association for Standardization and Certification (AENOR) issued the Spanish UNE 166002: 2006, the first innovation management standard, as sets of principles intended to aid organizations in navigating the multifaceted process of innovation, schematizing their activities and improving management efficiency.

Ultrasound and HPP to Control Fruit Enzymatic Browning
Polyphenoloxidase (PPO) is an endogenous enzyme, which is naturally present in plant tissues, and it has also been referred to as polyphenol oxidase, catechol oxidase, tyrosinase, phenolase, catecholase, and o-diphenol oxidase. It is an oxidoreductase-copper-containing metalloprotein, which catalyses the degradation of phenolic fruit constituents to o-quinones in the presence of oxygen. The combination of ultrasound with temperature, and high pressure processing (HPP) with temperature to inactivate polyphenoloxidase enzyme in three fruits (pear, apple and strawberry) was investigated and compared with PPO inactivation exclusively by a thermal process.

Microprobe System for Coordinate Metrology
A coordinate measuring machine (CMM) is a measuring instrument that can measure three-dimensional (3D) shapes of an object, including a probing system to detect an object’s surface, a positioning stage system to move either the probing system or the object, length scales to determine the coordinate of detected points by the probing system, as well as software to control the entire measurement.  Micro-coordinate measuring machines (micro-CMMs) for measuring microcomponents require a probe system with a probe tip diameter of several tens to several hundreds of micrometers. Scale effects work for such a small probe tip, i.e., the probe tip tends to stick on the measurement surface via surface adhesion forces. These surface adhesion forces significantly deteriorate probing resolution or repeatability.
