Long-term water chemical trends in two Swedish lakes after termination of liming

Lime treatment has been extensively used as a remedial measure against acidification of surface waters. In view of the decreasing acid deposition, the possible consequences of a termination of liming are discussed intensively in Sweden. This paper presents the results of the first study of long-term effects of termination of liming. The temporal trends in water chemistry were studied in two lakes after termination of liming, in a still-limed lake and in an unlimed reference lake. The lime treatment was intentionally stopped in order to evaluate the effects on water chemistry and biota. After the last liming, pH decreased steadily in both reacidifying lakes until annual mean values stabilised around 5.5-6.0 and 6.2-6.5 respectively. ANC and concentrations of non-marine Ca + Mg decreased after the termination of liming. The decreasing pH resulted in increasing trends of inorganic Al (Al_i), which during recent years exceeded the lowest known effect level for fish on several occasions. This indicates that the lime treatment may have been terminated to early from an ecological perspective and with respect to the critical load of acidifying substances during the study period. However, during the same time, non-marine sulphate decreased in all lakes in the study and pH and ANC increased in the unlimed reference lake.

Multimodal research in vision and language: A review of current and emerging trends

Deep Learning and its applications have cascaded impactful research and development with a diverse range of modalities present in the real-world data. More recently, this has enhanced research interests in the intersection of the Vision and Language arena with its numerous applications and fast-paced growth. In this paper, we present a detailed overview of the latest trends in research pertaining to visual and language modalities. We look at its applications in their task formulations and how to solve various problems related to semantic perception and content generation. We also address task-specific trends, along with their evaluation strategies and upcoming challenges. Moreover, we shed some light on multi-disciplinary patterns and insights that have emerged in the recent past, directing this field toward more modular and transparent intelligent systems. This survey identifies key trends gravitating recent literature in VisLang research and attempts to unearth directions that the field is heading toward.

Impacts of climate change on building performance in New Zealand

Climate change is expected to impact on many aspects of building performance, with much of the existing and future building stock likely to be affected. Potential impacts of climate change on buildings are identified, evaluated as to how serious they might be, and actions are considered to ensure that future building performance is not compromised. Climate change scenarios for New Zealand defined the scale of climate changes considered for building performance. For each climate variable, relevant aspects of building performance were examined to determine if there is likely to be a significant impact. Where significant impacts were indicated, they were studied in detail and quantified where possible. A risk-profiling tool was formulated to cover the risk/severity of the most significant climate change impacts, which include flooding, tropical cyclones and overheating. Adaptation strategies were developed for each climate change impact, with different responses appropriate for each impact. Mitigation of greenhouse emissions is also addressed. For those risks where delaying action has serious consequences, it may be appropriate to consider changes in building or zoning regulations to anticipate the future impacts of climate change. Some implications for future building performance, design, standards and regulation are discussed.

On peut s'attendre à ce que les changements aient des incidences sur de nombreux aspects des performances des bâtiments et que la majorité des bâtiments existants et futurs soit touchée. Cet article recense les conséquences potentielles des changements climatiques sur les bâtiments, les évalue quant à leur gravité et étudie les mesures à prendre pour que les performances des futurs bâtiments ne soient pas compromises. La Nouvelle-Zélande a étudié des scénarios de changements climatiques pour définir leur échelle en fonction des performances des bâtiments. Pour chaque variable climatique, on a examiné les aspects pertinents des performances des bâtiments afin de déterminer si elle est susceptible d'avoir un impact significatif. Lorsque c'est le cas, ces impacts ont été étudiés en détail et, dans la mesure du possible, quantifiés. On a conçu un outil de profil des risques pour couvrir les risques et la gravité des conséquences les plus importantes des changements climatiques, ce qui inclut les inondations, les cyclones tropicaux et les vagues de chaleur. Pour chaque conséquence des changements climatiques, on a formulé des stratégies d'adaptation, avec différentes réponses appropriées à chaque impact. On a également étudié l'atténuation des émissions de gaz à effet de serre. Quant aux risques pour lesquels tout retard dans les mesures à prendre aurait des conséquences sérieuses, il pourrait être judicieux d'envisager de modi? er la réglementation concernant les bâtiments ou le zonage afin d'anticiper les conséquences futures des changements climatiques. Cet article traite également de certaines implications pour les futures performances des bâtiments, conceptions, normes et réglementations.
