Lattice Boltzmann Method
Biofilm growth and evolution are very complex interactions among physicochemical and biological processes. Mathematical models are critical to modern biotechnology—both in research and in the engineering practice. Thus, many models of biofilms have been developed to include various biofilm reactor modules. However, considerable challenges exist in modelling microbial processes where mesoscopic dynamics of nutrient transport must be coupled with microscopic bacteria growth and their elementary biochemical reactions at reactive or enzymatic interfaces, in addition to the microbiological and/or ecological aspects of the “micro” organisms involved in biofilms. Lattice Boltzmann Method (LBM) treats flows in terms of fictive parcels of particles which reside on a mesh and conduct translation according to collision steps entailing overall fluid-like behavior. The goal of this review is to discuss and identify the opportunities of applying different LBM-based models to specific areas of biofilm research as well as unique challenges that LBM-based models must overcome.

Dinheirosaurus
Dinheirosaurus is a genus of diplodocid sauropod dinosaur that is known from fossils uncovered in modern-day Portugal. It may represent a species of Supersaurus. The only species is Dinheirosaurus lourinhanensis, first described by José Bonaparte and Octávio Mateus in 1999 for vertebrae and some other material from the Lourinhã Formation. Although the precise age of the formation is not known, it can be dated around the early Tithonian of the Late Jurassic. The known material includes two cervical vertebrae, nine dorsal vertebrae, a few ribs, a fragment of a pubis, and many gastroliths. Of the material, only the vertebrae are diagnostic, with the ribs and pubis being too fragmentary or general to distinguish Dinheirosaurus. This material was first described as in the genus Lourinhasaurus, but differences were noticed and in 1999 Bonaparte and Mateus redescribed the material under the new binomial Dinheirosaurus lourinhanensis. Another specimen, ML 418, thought to be Dinheirosaurus, is now known to be from another Portuguese diplodocid. This means that Dinheirosaurus lived alongside many theropods, sauropods, thyreophorans and ornithopods, as well as at least one other diplodocid. Dinheirosaurus is a diplodocid, a relative of Apatosaurus, Diplodocus, Barosaurus, Supersaurus, and Tornieria. Among those, the closest relative to Dinheirosaurus is Supersaurus.

Mechanism of Remediation of Contaminated Soil by Nanoparticles
The varied sources of soil pollution include the application of chemical fertilizers and pesticides, industrial discharge, and transformed products of these accumulated chemical residues. These processes may hamper the composition and soil ecosystem. Different types of methodologies ranging from physical, chemical, and biological approaches have been exploited to tackle this challenge. Nanomaterials (NMs) research has contributed to a new dimension for the remediation of polluted soils.

Phosphorus Recovery from Sewage Sludge Ash
Phosphorus is an essential and limited element that cannot be replaced by any other. Phosphorus deposits in the world are rapidly depleting, so methods of recovering phosphorus from alternative sources and using it as a fertilizer in agriculture are becoming increasingly popular. Struvite from sewage sludge ash contains phosphorus, and also a significant amount of nitrogen and magnesium. It is considered an effective slow-release fertilizer that can be successfully applied to agricultural, vegetable, and ornamental crops. The slower leaching of nutrients and high fertilizer quality, and high phosphorus content can make struvite an environmentally friendly fertilizer. However, its production is not yet sustainable. The cradle-to-cradle (C2C) concept has made it possible to highlight the so-called critical points in the production of such fertilizer. Limitations are environmental (concerns about heavy metals content in sewage sludge ash), legal (standard testing, product certification, quality control), economic (cost of energy, supply-chain), legal aspects (still not implemented as a mineral fertilizer under general EU regulations) and looses during P fertilizer production.

Soil Nanoremediation and Mushrooms
Soil pollution is a serious challenge facing the global community. This pollution is a direct and/or indirect harmful deterioration, which penetrates all aspects of our life, especially human health. Therefore, there is an urgent need to repair, remove, or decompose these pollutants according to various approaches. Concerning the relationship between soil nanoremediation and its mushrooms, this process can be called nano myco-remediation. The mechanism of this kind of remediation depends mainly on the enzymatic system of mushroom species and is involved in the bioremediation of organic environmental pollutants.

Appalachia (Mesozoic)
During most of the Late Cretaceous (100.5 to 66 million years ago) the eastern half of North America formed Appalachia (named for the Appalachian Mountains), an island land mass separated from Laramidia to the west by the Western Interior Seaway. This seaway had split North America into two massive landmasses due to a multitude of factors such as tectonism and sea-level fluctuations for nearly 40 million years. seaway eventually exapanded, divided across the Dakotas, and by the end of the Cretaceous, it retreated towards the Gulf of Mexico and the Hudson Bay. This left the island masses joined in the continent of North America as the Rocky Mountains rose. From the Cenomanian to the end of the Campanian ages of the Late Cretaceous, Appalachia was separated from the rest of North America. As the Western Interior Seaway retreated in the Maastrichtian, Laramidia and Appalachia eventually connected. Because of this, its fauna was isolated, and developed very differently from the tyrannosaur, ceratopsian, hadrosaurid, pachycephalosaur and ankylosaurid dominated fauna of the western part of North America, known as "Laramidia". Due to the fact that Appalachia was largely flat and had less erosion compared to Laramidia, no terrestrially formed deposits have survived, with most dinosaur remains originating from seaborne carcasses that were transported into marine environments. Some sediments have been removed by glacial erosion during the last ice age, but it is difficult to ascertain how much sediment has been removed, or whether these sediments would have been any more productive than those that remain. Thus relatively little is known about Appalachia in comparison to Laramidia, with exception of plant life, marine life and the insects trapped in amber from New Jersey. In addition, due to a lack of interest in Appalachia, many fossils that have been found in Appalachia lie unstudied and remain in the inaccurate genera to which they were assigned in the days of E. D. Cope and O. C. Marsh. Only a few fossils of the terrestrial creatures that were found in this region have given us a brief glimpse into what life was like here during the Cretaceous period. However, the area has seen a bit of a resurgence of interest due to several discoveries made in the past few years. As mentioned earlier, not much is known about Appalachia, but some fossil sites, such as the Woodbine Formation, Navesink Formation, Ellisdale Fossil Site, Mooreville Chalk Formation, Demopolis Chalk Formation, Black Creek Group and the Niobrara Formation, together with ongoing research in the area, have given us a better look into this forgotten world of paleontology.

Carterton, New Zealand
Carterton (Māori: Taratahi) is a small town in the Wellington Region of New Zealand and the seat of the Carterton District (a territorial authority or local government district). It lies in a farming area of the Wairarapa in New Zealand's North Island. It is located 14 km (8.7 mi) southwest of Masterton and 80 km (50 mi) northeast of Wellington. The town has a population of 5,850 (June 2021), out of a total district population of 10,050. Carterton was founded in 1857. Originally known as Three Mile Bush, it served as housing for workers building the road between Wellington and Masterton. It was later renamed after Charles Carter, who was in charge of the building of the Black Bridge over the Waiohine River south of the town. The town describes itself as New Zealand's daffodil capital, holding a Daffodil Festival each year on the second Sunday in September, with the main event taking place at Middle Run along Gladstone Road.
