Areal rates of CO2 production were 28.8 and 39.3 mg C m-2 d-1 (two experiments, October 2018). Sub-surface (1.1 cm) rates were strongly related to light levels, reaching a maximum of 0.68 mg C l-1 d-1 in September. Complete photo-oxidation ceased below 29.6 mW cm-2 d-1 UV radiation, providing a daily baseline for observable production of CO2. Absorbance indices changed by 9 to 14% d-1 at high light levels, except for R254/365 (4.4% d-1). Fluorophore emission ranges were stable between 2014 and 2018, indicating that emissions can be compared across time and space. This study contributes to better estimates and understanding of photo-oxidation in tropical, black-water rivers, which will be useful for carbon modelling.In the Saint-Marcel cave (France), wood barrels and thousands of bottles containing red wine were stored for vinification. After storage began, a fungal and bacterial outbreak occurred, and the area was invaded by numerous types of mold colonizing the cave ceilings and all objects related to human activities (the stairwell and oenological materials). In this study, using the metabarcoding approach, we have studied the microbial outbreak and have linked the identified microorganisms to oenological activity. Both 16S and ITS primers were used to sequence the samples collected from the cave. The results showed that the dominant microorganisms proliferating in the cave were related to wine vinification. For instance, Zasmidium cellare, a strain known for living in dark and ethanol-rich environments, was the dominant fungus on the cave stairwell. Furthermore, Guehomyces pullulans, a cold-adapted yeast used for juice clarification, was recorded as the major species on the blackened limestone ceilings. These findings reveal a complex community structure in the studied cave based on the assembly of bacteria and fungi. Finally, our results demonstrate that oenological activities could seriously affect cave preservation, changing the natural microbial communities populating cave environments.Electronic waste (E-Waste) is a progressively increasing problem for all developing nations. Developing nations like Pakistan, India and China are well renowned for the business of e-waste recycling. With the current rudimentary techniques of recycling used in Pakistan, e-waste presents different risks to the environment and the society with nominal financial gain. The study looks to answer how the e-waste makes its way to Pakistan, what are the risks of the industry and how they affect the population of Pakistan. For this purpose, a method called Modified-Safety Improve Risk Assessment (Modified-SIRA) was used. Modified-SIRA has identified six risks which are a severe hazard to a developing nation such as Pakistan. Each individual risk has been quantified by assigning it with an individually calculated Total Risk Priority Number (TRPN). Furthermore, the risks have been prioritized by the use of Fuzzy-VIseKriterijumska Optimizacija I Kompromisno Resenje (FVIKOR) to assess their impact on the sustainability of the e-waste recycling industry. This study provides evidence that among various risks air pollution from the e-waste recycling process is a severe hazard to the population of a developing country like Pakistan. It further helps to highlight the fact that the population of a developing country tend to ignore e-waste emanating from their expanded use of electronics. Additionally, the present use of rudimentary and non-standardized techniques of material extraction does not possess the capability of sustainably financing the industry. The study further concludes as to which practices and methods can be applied to reduce the impacts and improve the overall sustainability of the industry.Background Research on visuospatial functioning has revealed cognitive challenges for children with autism spectrum disorder (ASD), nonverbal learning disability (NLD) and attention deficit hyperactivity disorder (ADHD).
