Cardiovascular disease leading to heart failure (HF) remains a leading cause of morbidity and mortality worldwide. Improved pharmacological and interventional coronary procedures have led to improved outcomes following acute myocardial infarction. This success has translated into an unforeseen increased incidence in HF. This review summarizes the signaling pathways implicated in the transition to HF following cardiac injury. In addition, we provide an update on cell death signaling and discuss recent advances in cardiac fibrosis as an independent event leading to HF. Finally, we discuss cell-based therapies and their possible use to avert the deteriorating nature of HF. © 2019 American Physiological Society. Compr Physiol 9:75-125, 2019.

Hybrid organic-inorganic perovskites (HOIPs) have been previously compounded with hydrophobic polymers in order to improve the resilience of HOIPs in humid environments. In this study HOIP particles were synthesized and dispersed into a polymer solution. The weight loading of the HOIP phase in the composite was increased until an abrupt change in the electrical conduction was observed indicating a percolation threshold was approached. Additionally, the CH3NH3PbI3/ polystyrene composite media was characterized to assess morphology and the effect it has on the observed electrical properties.

IEC 61400-3 (2009) and GL Offshore guideline (2012) are two commonly adopted guidelines for certification of offshore wind turbines worldwide. Comparison of load calculation during normal and idling situations between these two guidelines is performed in this paper. The NREL 5 MW wind turbine with monopile support structure is selected as the reference wind turbine system. Study of the impact on the loading conditions is conducted in this paper. Design load case (DLC) 1, 6, and 7 are considered in this work and the focus is on the Class I system with different turbulence characteristics (category A, B, and C). Both of extreme and fatigue loads are derived at critical components such as blade, shaft, tower, and foundation. The major impact is investigated and identified in this paper.

Screw rotors of a twin screw compressor often deform and interfere due to the cyclic gas pressure and working temperature, which lead to noise, vibration and abrasion of the screw rotors. Therefore, this paper proposed a simplified CAE (Computer Aided engineering) method instead of the past massive and complex CFD (Computational Fluid Dynamics) method to simulate and estimate reasonably the screw rotor load and deformation with considering the gas pressure and working temperature applied on its operating process. The analysis results could provide the possible maximum rotor deformation and cyclic load acting on the rotors for design consideration.

The effect of applied electric fields on the spreading flame over slanted Polyethylene (PE) insulated electrical wire was investigated experimentally by varying the AC frequency and voltage. The result showed that the spread rate of downwardly spreading flame decreased in increase of voltage and frequency, while that of upward flame spread rate exhibited complicated behavior with applied voltage and frequency. Downwardly spreading flame size became smaller in increase of applied voltage and frequency, while the flame leaned toward burnt side. When the flame spread upwardly, the flame size experienced large variation with applied voltage and frequency. Such flames leaned toward unburned side. Based on flame shape and the slanted direction of flame, the flame spread rate could be explained by thermal balance mechanism.

WPA Mk II Project started in 2011 in response to the ESA spare procurement philosophy for ISS life extension up to 2020 (and possibly beyond 2020). The project involves TASI as responsible for the design, development, manufacturing, integration and testing of this new water pump package for the ISS Columbus module. This pump package is responsible for the circulation of water inside Columbus pipelines to ensure proper thermal control not only for the Payloads (PL's), but also for the cabin where astronauts work and live, and consequently represents the core of the Thermal Control system in Columbus. WPA Mk II is characterized by several innovations in comparison with the current WPA Mk I installed in Columbus, like new functionalities (on board SW uploading capability), or new technologies (ultrasonic flow meter), up to a high level modular design (characterized by several ORUs, on Orbit Removable Units, conceived to optimize R&R operations and associated time and costs). A successful Critical Design Review has been achieved in July 2014, in Turin, with the support of the European Space Agency and Airbus. Now TASI is approaching MAIT phase: in the 2015 there will be the integration and testing of the various ORUs while the 2016 will be characterized by the integration and testing of the two pump packages WPA Mk II to demonstrate system compliance to the launchers and Columbus environmental and functional requirements. The present article provides an overview of the Project, the main features, the mission scenarios, and a general overview about the associated Qualification plan at Component, ORUs and Assy level.

Energy consumption of buildings worldwide has steadily increased over the past couple of decades. Furthermore, energy performance of buildings is one of the factors that contribute to energy waste and its perennial adverse impact on the environment. This paper presents a data mining approach for assessing the heating and cooling requirements of residential buildings. The proposed approach combines Artificial Neural Networks (ANNs) and cluster analysis to assess and predict the heating and cooling energy efficiency of residential buildings. The ANN-based model uses eight input variables (i.e., relative compactness, surface area, wall area, roof area, overall height, orientation, glazing area, and glazing area distribution) to predict both the heating and cooling loads of residential buildings. Buildings are then clustered based on the output variables using the K-means clustering method. The proposed approach is used to assess and evaluate 768 diverse residential buildings based on simulated literature data. The research results showed that the proposed approach can effectively predict the heating and cooling requirements of residential buildings based on the input variables considered with a very high level of accuracy.

This paper presents a workplace ergonomic study in a high-end server manufacturing environment to assess ergonomics risks and enhance the Lean transformation. Operators perform heavy and repetitive lifting and movement of products could place stress on their back and upper extremities. Forceful exertions to move a manual forklift in the workplace area could lead to fatigue and possible damage to muscles and other tissues. The objective of this study is to reduce ergonomics risks to an acceptable level and provide operators with the right tools and proper work environment. Digital human modeling based on the Jack software, is used for risk assessment. Results are analyzed to provide proper solutions. Ergonomic risks assessed include: force and posture risks, noise, vibration, temperature, and illumination. Lean process is implemented in the workplace to reduce the Lean wastes that include waiting time, transportation, and non-value-add processes. Ergonomic improvements are introduced to complement and support the Lean process implementation. Three main ergonomic risks are found to be high and could affect the operators: energy expenditure, posture, and back force. Several modifications are implemented to reduce these risks: the manual forklift is replaced with an automated forklift that is easy to move and requires less human effort, the workplace area is expanded to provide more work space, and the operators are provided with proper tools to perform the task without risk.
