This study presents an approach for obtaining realization sets of parameters for nitrogen removal in a pilot-scale waste stabilization pond (WSP) system. The proposed approach was designed for optimal parameterization, local sensitivity analysis, and global uncertainty analysis of a dynamic simulation model for the WSP by using the R software package Flexible Modeling Environment (R-FME) with t...
Wolbachia are a group of intracellular inherited bacteria that infect a wide range of arthropods. They are associated with a number of different reproductive phenotypes in their hosts, such as cytoplasmic incompatibility, parthenogenesis and feminization. While it is known that the bacterial strains responsible for these different host phenotypes form a single clade within the alpha-Proteobacte...
Many states have passed legislation that regulates agricultural P applications based on soil P levels and crop P uptake in an attempt to protect surface waters from nonpoint P inputs. Phytase enzyme and high available phosphorus (HAP) corn supplements to poultry feed are considered potential remedies to this problem because they can reduce total P concentrations in manure. However, less is know...
Understanding the connections among genotype, phenotype, and fitness through evolutionary time is a central goal of evolutionary genetics. Wrinkly spreader (WS) genotypes evolve repeatedly in model Pseudomonas populations and show substantial morphological and fitness differences. Previous work identified genes contributing to the evolutionary success of WS, in particular the di-guanylate cycla...
The aim of this study was to determine the degradation resistance of three new formulations-silorane-, Ormocer- and dimer-acid-based materials-and compare them to the traditional dimethacrylate-based materials. One silorane- (Filtek P90, P90), one Ormocer- (Ceram-X, CX), one dimer-acid- (N'Durance, ND) and two dimethacrylate-based (Filtek P60, P60; Tetric Ceram, TC) materials were investigated....
In the developing nervous system, axons are guided to their targets by the growth cone. Lamellipodial and filopodial protrusions from the growth cone underlie motility and guidance. Many molecules that control lamellipodia and filopodia formation, actin organization, and axon guidance have been identified, but it remains unclear how these molecules act together to control these events. Experime...
Passive wastewater treatment systems are commonly applied in northern Canadian communities. Pathogen removal in these systems, which relies on natural purification, can be greatly affected by Arctic environmental conditions. In 2012, new Wastewater Systems Effluent Regulations (WSER) were implemented in Canada, but not in the far North due to the number of northern communities with limited wast...
سه گونه پسیل زبان گنجشک، Psyllopsis repens Loginova 1963، Psyllopsis securicola Loginova 1963 و Psyllopsis machinosus Loginova 1963 که در آسیای مرکزی و اروپا گسترش دارند، از آفات مهم زبان گنجشک در مناطق شهری ایران محسوب میشوند. حشرات بالغ و پوره ها، و همچنین میزبان و زیست شناسی آنها بسیار شبیه به هم است. به عبارتی دیگر، شناسایی ریخت شناختی آنها، به ویژه ماده...
The Water and Sanitation Program is a multi-donor partnership administered by the World Bank to support poor people in obtaining affordable, safe, and sustainable access to water and sanitation services. thanks go to them for their constant interest in this topic and their intellectual generosity. Global Scaling Up Handwashing is a Water and Sanitation Program (WSP) project focused on learning ...
