Biological growth on mineral façades
… on newly built rendered façades in Sweden due to biological growth. The problem is believed to occur mostly on façades of render applied on thermal insulation, but apart from this it is difficult to find clear relationships indication which façades might be infected. The aim of this project is to …

Biological growth on rendered façades
Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with …

Biological Aerated Filters: Oxygen Transfer and Possible Biological Enhancement
A submerged-media biological aerated filter (BAF) has been studied to 1) evaluate oxygen transfer kinetics under conditions without biological growth and 2) determine the influence of biological growth on the rate of oxygen transfer. Collectively, the study evaluates the rates of supply and …

Aquaculture and pollution studies of an Australian fish: silver perch, Bidyanus bidyanus (Mitchell 1838) (Teraponidae)
… was undertaken primarily to investigate the biological growth of silver perch juveniles fed on artificial and sewage grown zooplankton, and quantifies solid and nutrient load from rearing of silver perch at different temperatures. The present study demonstrated that silver perch can grow …

Statistical Evaluation of the Factors causing Microbial Growth in Point-of-use Filters
… of POU filter could possibly lead to the growth of bacteria inside the filters, which could lead to health concerns. Therefore, the potential effects of POU filters on microbial growth was investigated. To explore the cause of filter effects on microbial growth, a sampling campaign was …

Understanding the microbiota in drinking water distribution networks – from municipal to indoor water supply systems
… pipelines and is prone to stagnation, therefore biological growth is expected. However, the magnitude of biological growth and the possible community composition change is not clear. Thus, we examined the impact of stagnation on the community composition in the tap water community. We treated …

Modelling techniques for biological systems
… appropriate to the modelling and simulation of biological reaction system behaviour. The model used as the basis for analysis of modelling and simulation techniques is a reduced version of the biological model proposed by the IAWPRC Task Group for mathematical modell ing in wastewater treatment …

A Technical Study of the Mural Paintings of the Interior Dome of the Capilla de la Virgen del Rosario, Iglesia San José, San Juan, Puerto Rico
… including abundant chloride salts, and biological growth contributing to failing paint layers and plasters. The Rosario Chapel murals are highly significant and warrant a comprehensive strategy for their conservation and interpretation through a collaborative process involving all …

Moisture Buffering in the Indoor Environment
… an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g., mold growth on walls and house dust mites in beds, and thereby also have an impact on the health of the inhabitants. Apart from the health aspects, moisture buffering is also …

Microalgae-derived HEFA jet fuel : environmental and economic impacts of scaled/integrated growth facilities and global production potential
… are constrained by geographically variable biological growth factors in addition to water/CO₂ transportation constraints, land availability and slope, and industrial CO₂ availability. Maximum jet and maximum distillate product slates were applied to total energy potential results to quantify …

Mechanisms Of Nanofilter Fouling And Treatment Alternatives For Surface Water Supplies
… adsorption, particle plugging, and attached biological growth. Fouling was addressed by addition of acid and antiscalent for control of precipitation, addition of monochloramine for control of biological growth, microfiltration (MF) or coagulation-sedimentation-filtration (CSF) for control of …

Paths Towards Shape Change: Elastic Instabilities and Spontaneous Deformations
… change — via spontaneous defor- mations — are biological growth or muscle contraction. They sculpt the shape of flowers or power the beating of a heart. Outside of the realm of biology, the swelling of gels and the anisotropic deformations in liquid crystal elastomers (LCEs) are two excellent …

Understanding the mechanics of growth: A large deformation theory for coupled swelling-growth and morphogenesis of soft biological systems
Understanding the growth of soft biological systems is crucial in a wide range of applications with extensive societal consequences, such as plastic and reconstructive surgery, curbing the growth of tumors and bacterial colonies, tissue engineering of functional vascular grafts, etc. Solid tumors …
