Abstract:
Introduction: The conditioning procedures for glass-based ceramic restorations before adhesive cementation are generally recognized. In the case of polycrystalline ceramics, which include zirconium oxide, there is still no standardized protocol. The aim of this work was to present conditioning methods of the cementation surface of zirconium oxide fixed dentures. The new generation high translucency zirconia has been also considered. Material and method: The following keywords for the PUBMED and EMBASE databases were used: zirconium oxide, zirconium oxide with increased translucency, bond stren

In large spaces, the comfort control of radiant air conditioning systems still has deficiencies. Mainly reliant on traditional parameter control methods, the interaction effects of diverse operating conditions are not taken into account, and the control results are still in need of optimization. To improve indoor air conditioning comfort control and address gaps in existing research, the response surface analysis method combined with numerical simulation is applied to determine the optimal air supply conditions for large-space radiant air conditioning.

This research examines the performance of green roof architectural designs in enhancing energy efficiency in buildings within tropical and subtropical climates. Green roofs, which integrate vegetation and planting media, can improve energy efficiency by reducing the heat absorbed by buildings, thereby increasing indoor thermal comfort and lowering the need for air conditioning. The study employs a comparative method to analyse the performance of green roofs in improving energy efficiency across both climates.

Abstract:
After dental implants are manufactured there can be a loss of biological activity that may be reactivated by exposure to ultraviolet (UV) radiation, that is, photofunctionalization. The titanium surface is energy conditioned by UV radiation. This imparts a slight positive surface energy and hydrophilicity to the titanium dental implant surface. This conditioning renews biological activity lost after a shelf life of as little as 2 weeks. The UV radiation has chemical and biological effects on the osseous-implant interface. Photofunctionization for as little as 15 minutes accelerates healing and

Abstract:
The urban heat island, where the urban area air temperature is higher than the nearby rural or semi-rural air temperature reference site, is now hopefully well known. The urban heat island intensity is the actual urban air temperature minus the rural air temperature. However, the “air conditioned urban heat island intensity” is measured by the air temperature sensor in an air conditioning condenser unit minus the rural air temperature. This is often different to the standard urban heat island intensity. Designers need to appreciate this difference, as it determines how the air conditioning sys

Abstract Cool coatings can play an important role in reducing global energy consumption and increasing interior comfort. They do this by minimizing solar absorption on a surface whilst maximizing thermal emission. Used in this way, a cool coating is able to reduce the flow of heat from the exterior coated surface into the building, resulting in lower internal temperatures. The reduction in the internal temperature can reduce the need for electricity used to power air conditioning units used for cooling.

Abstract:
The Cerrado is a natural biome occupying 25 per cent of Brazil’s surface. Compared to the Amazon, it is relatively unknown to international audiences, yet it is currently the world’s largest agricultural frontier. Intensive soybean and beef production are driving deforestation, water depletion, habitat loss, and land grabbing. Emphasising the scale of land-based inequality and conflicts, this briefing exposes the Cerrado as a territory of martyrdom, contrasting the ‘miracle’ portrayed by the dominant agri-food regime. Resistance struggles within the region are outlined and recommendations look

Abstract:
Laser and electron-beam powder bed fusion (PBF) additive manufacturing (AM) technology has transitioned from prototypes and tooling to production components in demanding fields such as medicine and aerospace. Some of these components have geometries that can only be made using AM. Initial applications either take advantage of the relatively high surface roughness of metal PBF parts, or they are in fatigue, corrosion, or flow environments where surface roughness does not impose performance penalties. To move to the next levels of performance, the surfaces of laser and electron-beam PBF componen

Abstract:
The world is facing a rapid increase of air conditioning of buildings. It is the motivation of Annex 80 to develop, assess and communicate solutions of resilient cooling and overheating protection. Resilient Cooling is used to denote low energy and low carbon cooling solutions that strengthen the ability of individuals and our community to withstand, and prevent, thermal and other impacts of changes in global and local climates. Within Annex 80, there is a manifold need to use key performance indicators (KPI, i.e. performance metrics). This study employs a structured approach to evaluate Key P

Abstract:
This research focuses on developing two analytical methods for forensic investigations using electrochemical detection and surface-enhanced Raman spectroscopy. For electrochemical analysis, screen-printed carbon electrodes are used to detect metals and nitrate/nitrite compounds commonly found in gunshot residue. Gold electrodeposition and copper modification enhance sensitivity and catalytic activity, respectively. Additionally, a screen-printed gold electrode modified with gold nanoparticles enables surface-enhanced Raman spectroscopy, requiring only a single drop of sample solution. Testing

Abstract:
There is a need for renewable antimicrobial surface treatments that are semi- permanent, can eradicate both biofilms and planktonic pathogens over long periods of time and that do not select for resistant strains. This proposal describes a dopamine binding technology that is inexpensive, bio-friendly, non-toxic, and uses straight-forward commercially available products. The antimicrobial agents are peptidoglycanhydrolase enzymes that are non-toxic and highly refractory to resistance development. The goal of this project is to create a treatment that will be applicable to a wide variety of surf

Abstract:
R-22 (also known as HCFC-22) is one of the most widely used refrigerants in U.S. Army air-conditioning and refrigeration (AC&R) systems since the phase-out of R-12 refrigerant in 1995. The need to phase out R-22 is attributed to its global warming potential and high ozone-depleting capability. The U.S. Army has tens of thousands of aging AC&R systems that will remain dependent on R-22, or one of the recently developed substitutes for R-22, until they reach the end of their operational life. This project conducted a survey to understand the current R-22 usage and types of R-22 AC&R

Abstract:
The share of Latin American and Caribbean households led by women is rapidly increasing, at the same time as these households are overrepresented among those living in housing deficit. In this study, we looked at whether there is a gender gap in access to housing loans, one of the main tools available to housing. In addition, we explored which are the characteristics of FHHs and to which extent they can have an impact on their access to adequate housing. This study shows how FHHs face greater housing deficits. Our findings indicate that gender gaps in other areas, most importantly in labor mar

Full text
Abstract:
Oxidation catalysts are often utilized to reduce carbon monoxide, formaldehyde, and volatile organic compounds in order to meet emissions regulations for large bore natural gas engines. These catalysts degrade over time and need to be replaced or regenerated to maintain emissions compliance. This work evaluates the effectiveness of catalyst regeneration, or catalyst washing. The evaluation is performed by utilizing field and laboratory slip streams combined with catalyst module performance (reduction efficiency) measurements and catalyst material surface analysis to quantify catalyst poisons.
