Industry 4.0 and Lean Six Sigma Integration
In recent years, Industry 4.0 (I4.0) has been a recurrent theme in the literature on Lean Six Sigma (LSS), given the synergies that can arise from their combination. However, several factors can affect the integration of I4.0 and LSS in practice. This article presents a systematic literature review of the barriers to integration and the critical success factors (i.e., enablers) involved in this process.

Smart Manufacturing Systems
Smart Manufacturing is considered as a new paradigm that make work smarter and more connected, bringing speed and flexibility through the introduction of digital innovation. Today, digital innovation is closely linked to the “sustainability” of companies. Digital innovation and sustainability are two inseparable principles which are based on the concept of circular economy. Digital innovation enables circular economy model promoting the use of solutions like digital platforms, smart devices, artificial intelligence that help to optimize resources. Thus, the purpose of the research is to present a systematic literature review on what enabling technologies can promote new circular business models.

Waste Heat Recovery Technologies Revisited with New Solutions
Waste heat recovery (WHR) has been a challenge for industries, as it can lead to energy savings, higher energy efficiency, and sustainability. WHR technologies are usually classified based on the output provided, namely heat recovery (HR) or heat-to-power (H2P) conversion.

Machine Learning for RC monitoring
The reciprocating compressor (RC) is a key piece of equipment in petroleum and chemical industries. If the RC does not operate in the rated efficiency, it will lead to great economic loss to the company. Sometimes RCs are used to compress inflammable and explosive gases working under high pressures and temperatures, such as hydrogen, ethylene, and natural gas, which would threat human life once the machine malfunctions. Furthermore, due to the intricate structure of the compressor, a large amount of wearing parts, and the complicated interactional relationship between moving parts of the compressor, it is essential to monitor the compressor operating condition and detect failures of RCs accurately and in a timely manner. Operating condition detection and fault diagnosis are very important for reliable operation of reciprocating compressors. Machine learning is one of the most powerful tools in this field.

Competitive Swimwear
Competitive swimwear refers to the swimsuit, clothing, equipment, and accessories used in the aquatic sports of swimming, diving, synchronized swimming, triathlon, and water polo. Some swimsuits are designed specifically for swimming competitions where they may be constructed of a special low resistance fabric that reduces skin drag. For some kinds of swimming and diving, special bodysuits called "diveskins" are worn. These suits are made from spandex and provide little thermal protection, but they do protect the skin from stings and abrasion. Most competitive swimmers also wear special swimsuits including partial bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage. Unlike regular swimsuits, which are designed mainly for the aesthetic appearances, swimsuits designed to be worn during competitions are manufactured to assist the athlete in swim competitions. They reduce friction and drag in the water, increasing the efficiency of the swimmer's forward motion. The tight fits allow for easy movement and are said to reduce muscle vibration, thus reducing drag. This also reduces the possibility that a high forwards dive will remove a divers swimwear. Starting around 2000, in an effort to improve the effectiveness of the swimsuits, engineers have taken to designing them to replicate the skin of sea-based animals, sharks in particular. In July 2009, FINA voted to ban non-textile (non-woven) swimsuits in competitive events from 2010. The new policy was implemented to combat the issues associated with performance enhancing swimsuits, hindering the ability to accurately measure the performance of swimmers. Subsequently, the new ruling states that men's swimsuits may maximally cover the area from the navel to the knee, and women's counterparts from the shoulder to the knee. Some swimmers use a specialized training suit called drag suits to artificially increase drag during practice. Drag suits are swimwear with an outer layer of looser fabric – often mesh or nylon – to increase resistance against the water and build up the swimmer's endurance. They come in a variety of styles, but most resemble a looser fitting square-cut or swim brief.

Respirator Cartridge
A respirator cartridge or canister is a container that cleans pollution from air. People working in polluted atmospheres use respirators for health preservation. If the air in the workplace is polluted with noxious gases, but contains sufficient oxygen (>19.5% in US; >18% in RF) they often use air-purifying respirators (APR). These respirators provide users breathable air by removing pollution from ambient air using canisters or cartridges. There are cartridges of different types, and they must be chosen correctly and replaced in a timely manner.

Guard Rail
Guard rail, guardrails — or railings around properties and more generally outside of North America in some uses overlaps the industrial term "guide rail". They are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support.

Industry 5.0
Industry 5.0 presents itself as a strategy that puts the human factor at the centre of production, where the well-being of the worker is prioritized, as well as more sustainable and resilient production systems. For human centricity, it is necessary to empower human beings and, respectively, industrial operators, to improve their individual skills and competences in collaboration or cooperation with digital technologies.

Innovation Capacity in Developing Countries
Innovation is an intrinsic capacity of humankind, enabling the adaptation to changes and managing probable solutions to problems regarding its welfare or its surroundings. It constitutes a key driver of sustainable growth. Moreover, innovation capacity is among the dynamic capacities leading to achieving a competitive and sustainable advantage. Hence, by adopting innovative and R&D practices, a country might enhance its growth and competitiveness, particularly for a developing country. In addition, it encompasses diverse perspectives, e.g., organizational capacity, public capacity, regional capacity, national capacity, among others. Therefore, many public and private organizations have focused their efforts on identifying and quantifying the variables that determine the innovation capacity of a country. Various mechanisms have been proposed to assess this capacity, such as the national innovation capacity, Global Innovation Index (GII), Global Competitive Index (GCI) , or European Innovation Scoreboard (EIS). These mechanisms aim at providing an objective measurement of the performance of a country regarding innovation capacity or innovation as a means to competitiveness. Each one of these presents a particular set of determinants, methods, and interpretations to assess innovation.

NEV Battery GU and Recycling
Recycling and gradient utilization (GU) of new energy vehicle (NEV) power batteries plays a significant role in promoting the sustainable development of the economy. GU is an effective means to extend the life cycle of NEV batteries and recognize their value fully. GU refers to the retesting, screening, repairing, pairing, and reuse of power batteries that have been retired from NEV (their performance is reduced to less than 80% of initial performance) under relatively mild conditions. Batteries after GU can be disassembled, and they can be recycled (typically when the remaining capacity is less than 30%) to recover cobalt, lithium, and other precious metals to achieve the “win-win” of resource recovery and environmental protection.
