3D Bioprinting in Cardiac Tissue Engineering
Cardiovascular diseases are the leading cause of morbidity and mortality in the United States. Cardiac tissue engineering is a direction in regenerative medicine that aims to repair various heart defects with the long-term goal of artificially rebuilding a full-scale organ that matches its native structure and function. Three-dimensional (3D) bioprinting offers promising applications through its layer-by-layer biomaterial deposition using different techniques and bio-inks. Recent advancements in this field have improved 3D bioprinting accuracy and resolution and its latest applications span cardiac tissues, patches, organoids, and the full organ.

Efficiency of Mediterranean Container Ports
Container ports located in the wider Mediterranean area act as important maritime gateways connecting Europe, Asia and North Africa. They are considered as important and strategic nodes that facilitate intercontinental transport activities. Port performance is formed by a set of components, among which efficiency and effectiveness are two major interrelated ones.

CFD Analysis in LAA Thrombus Formation Risk
Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular and rapid electrical activity in the atria, leading to ineffective contraction and poor blood flow. More than 90% of the left atrial (LA) thrombi that cause thromboembolic events during atrial fibrillation (AF) develop in the left atrial appendage (LAA). Computational fluid dynamics (CFD) analysis can be used to better understand the risk of thrombus formation and subsequent embolic events.

Forward Osmosis Development
Forward osmosis (FO) has attracted special attention in water and wastewater treatment due to its role in addressing the challenges of water scarcity and contamination. The presence of emerging contaminants in water sources raises concerns regarding their environmental and public health impacts. Conventional wastewater treatment methods cannot effectively remove these contaminants; thus, innovative approaches are required. FO membranes offer a promising solution for wastewater treatment and removal of the contaminants in wastewater.

Feasibility of a 100% Global Renewable Energy System
Controversy exists as to whether renewable energy (RE) can provide for all the world’s energy needs. It is found that the energy that could be delivered by these two sources is much less than often assumed, for several reasons: The declining quality of inputs; the need for inclusion of uncounted environmental costs; the need for energy conversion and storage; and the removal of existing fossil fuel energy subsidies.

Use of Zinc Oxide in Asphalts
Zinc oxide (ZnO) is a wide-gap semiconducting material which is chemically stable at high temperatures and has been shown to be compatible with asphalt binders. Additionally, semiconducting nanoparticles such as ZnO could help to improve urban air quality. This has encouraged the use of this material as a binder and asphalt mix modifier.

Electromagnetic Fields Radiated by Electrostatic Discharges
Electrostatic discharge (ESD) is a physical phenomenon that may destroy electronic components due to its high discharge current that may reach a few amperes in just a few ns. However, another major aspect of ESD is the related high-frequency electromagnetic (E/M) fields radiated by the ESD event. The electronic equipment that is affected by the ESD phenomenon is additionally affected by the induced voltages caused by these E/M fields. This is the reason that the current version of the IEC 61000-4-2 on ESD has a special reference to these fields and the measurement setup.

Secure Sensor Prototype in a Blockchain Application
The security of Industrial Internet of Things (IIoT) systems is a challenge that needs to be addressed immediately, as the increasing use of new communication paradigms and the abundant use of sensors opens up new opportunities to compromise these types of systems. In this sense, technologies such as Trusted Execution Environments (TEEs) and Hardware Security Modules (HSMs) become crucial for adding new layers of security to IIoT systems, especially to edge nodes that incorporate sensors and perform continuous measurements.

Highway Safety Manual for Brazilian Multilane Highways
This research assesses the performance of Highway Safety Manual (HSM) predictive models when applied to Brazilian highways. The research evaluates five rural multilane highways and calculates calibration factors (Cx) of 2.62 for all types of crashes and 2.35 for Fatal or Injury (FI) crashes. The Goodness of Fit measures show that models for all types of crashes perform better than FI crashes.
