Use phase fuel consumption is responsible for the majority of an automobile's life cycle energy consumption and greenhouse gas (GHG) emissions. Lightweighting is an important strategy to reduce use phase fuel consumption and potentially reduce vehicle life cycle impacts. A popular lightweighting technique is material substitution, in which conventional materials (e.g., iron, steel) are replaced with lighter ones (e.g., aluminum, magnesium). Material substitution, however, often results in higher material production impacts.

According to the reports on critical raw materials for the EU, a raw material is considered critical if it has a high economic importance to the EU combined with high supply risk. Supply risk is considered to arise from a combination of several factors, namely a high concentration of production in countries with poor governance, limited material substitutability, and poor end-of-life recycling rates. A number of industry activities, policy initiatives and research projects have recently been initiated in Europe with the aim to secure an adequate supply of raw materials.

Over the past decade, raw material price spikes have called attention to the supply security of a variety of critical materials, including rhenium, rare earth elements, and helium. While market forces play an important role in creating and resolving these situations, transitions in technology also create step-changes in demand that increase or decrease the criticality of different materials. With an appropriate understanding of how materials are used in various applications, it is possible to explore the critical materials implications associated with the introduction of new technologies.

As the technologies we use as a society have advanced, so have the materials used in these technologies. Some of these materials are exotic and highly specialized, making them particularly vulnerable to supply disruptions and supply disruptions particularly impactful. Such materials are designated as “critical” materials. Their level of criticality can be identified by accounting for a number of factors related to their supply risk and the extent to which a supply disruption would impact business operations or society at large.

Background: Older adults are at increased risk of malnutrition compared to their younger counterparts. Malnutrition screening should be conducted using a valid malnutrition screening tool. An aim of the Healthy Diet for a Healthy Life (HDHL) Joint Programming Initiative (JPI) ‘Malnutrition in the Elderly Knowledge Hub’ (MaNuEL) was to review the reported validity of existing malnutrition screening tools used in older adults.

While the sale of non-timber forest products (NTFPs) is nearly invisible in and marginal to official economic statistics, it is an important source of income for many rural populations in Amazonia. This paper discuss a NTFPs production and marketing chain (Mauritia flexuosa fruits) in Abaetetuba County, Northern Brazil. Research was carried out using the following methods: participant observation, application of semi-structured questionnaires, and by accompanying production during harvest months in 2015.

Background: Concurrent psychosocial problems may synergistically increase the risk of HIV infection (syndemics), representing a challenge for prevention. We aimed to evaluate the prevalence and associated factors of syndemics among men who have sex with men (MSM) and transgender women (TGW) enrolled in the Brazilian pre-exposure prophylaxis demonstration study (PrEP Brasil Study). Methods: Secondary cross-sectional analysis of the PrEP Brasil Study was performed.

Objectives: This paper review trends in emerging infections and the need for increased clinical and laboratory surveillance. Methods: Factors that contributed to the emergence of recent outbreaks have been reviewed. Known, major outbreaks over the past two decades were reviewed. Results: We identified at least four major drivers of emergent infections: (i) increasing density of the human population; (ii) stress from farmland expansion on the environment; (iii) globalization of the food market and manufacturing; (iv) environmental contamination.

Data collection methods and poverty measures have not caught up with the reality of an increasingly urbanised world; as a result, urban poverty may be underestimated. This has important implications for targeting interventions and allocating resources in the 2030 Agenda for Sustainable Development.
