No living organism can live on earth without water. Today, 70 percent of water is used for agriculture, 20 percent for industrial work and 10 percent for human consumption worldwide. Fish, crocodile, crab, shrimp etc. were found as aquatic organisms during the Sangam period. They describe the nature of the environment in the manner of food chain, spread, space protection, food collection and storage, and coexistence with the law of nature. In 500, news of aquatic organisms and their spreading into a food chain, compliance with the natural law, food conservation, human use methods and environmental contacts have been explored. This article shows that aquatic organisms lived without any pollution and without loss of life during the Sangam period.

Previously, we showed for the first time that alkaliphilic fungi, in contrast to alkalitolerant fungi, accumulated trehalose under extremely alkaline conditions, and we have proposed its key role in alkaliphilia. We propose that high levels of trehalose in the mycelium of alkaliphiles may promote adaptation not only to alkaline conditions, but also to other stressors. Therefore, we studied changes in the composition of osmolytes, and storage and membrane lipids under the action of cold (CS), heat (HS) and osmotic (OS) shocks in the obligate alkaliphilic micromycete Sodiomyces tronii. During adaptation to CS, an increase in the degree of unsaturation of phospholipids was observed while the composition of osmolytes, membrane and storage lipids remained the same. Under HS conditions, a twofold increase in the level of trehalose and an increase in the proportion of phosphatidylethanolamines were observed against the background of a decrease in the proportion of phosphatidic acids. OS was accompanied by a decrease in the amount of membrane lipids, while their ratio remained unchanged, and an increase in the level of polyols (arabitol and mannitol) in the fungal mycelium, which suggests their role for adaptation to OS. Thus, the observed consistency of the composition of membrane lipids suggests that trehalose can participate in adaptation not only to extremely alkaline conditions, but also to other stressors – HS, CS and OS. Taken together, the data obtained indicate the adaptability of the fungus to the action of various stressors, which can point to polyextremotolerance.

The achievement of climate neutrality in the European Union by 2050 will not be possible solely through a reduction in fossil fuels and the development of energy generation from renewable sources. Large-scale implementation of various technologies is necessary, including bioenergy with carbon capture and storage (BECCS), carbon capture and storage (CCS), and carbon capture and utilisation (CCU), as well as industrial electrification, the use of hydrogen, the expansion of electromobility, low-emission agricultural practices, and afforestation. This research is devoted to an analysis of BECCS as a negative emissions technology (NET) and the assessment of its implementation impact upon the possibility of achieving climate neutrality in the EU. The modelling approach utilises tools developed within the LIFE Climate CAKE PL project and includes the MEESA energy model and the d-PLACE CGE economic model. This article identifies the scope of the required investment in generation capacity and the amount of electricity production from BECCS necessary to meet the greenhouse gas (GHG) emission reduction targets in the EU, examining the technology’s impact on the overall system costs and marginal abatement costs (MACs). The modelling results confirm the key role of BECCS technology in achieving EU climate goals by 2050.

<p>This research explores how Pacific and contemporary cultures cohesively blend through 3D printing to create a new identity for Pacific people. The project seeks to further the development of concerning issues surrounding Identity and diabetes within Pacific communities. Foreign preconceptions about the Pacific are been challenged here to create a new identity about the Pacific from a Pacific perspective. The extraction of these Pacific motifs will be explored through a Design realm, 3D printing, which contribute to the development of a contemporary Pacific.  The project seeks to explore the effects of type 1 diabetes on adolescents. In particular, with the managing and storage of their diabetic equipment’s while outside of home care. Pressures of adolescent years is added when diabetes is present, which can cause physiological disadvantages. Bike riding will be the scenario of choice, where storage kits for bikes are 3D printed. Pacific patterning is encouraged to help with the 3D printing process, the familiarity of Pacific patterning is to inspire my Pacific people in becoming active with diabetes. Participants will be used in this research to gain feedback and further the design, giving them a sense of autonomy through unique storage kits, portraying their identity.  Inspiration is drawn from my heritage, which is explored through my contemporary environment (Design), to portray my identity as a Pacific designer. This is evident throughout my experimentation whereas the incorporation of Pacific patterning and themes influence the final design.</p>
