Oxford Avenue Sewer Extension Project in the City of Portsmouth [PDF]

open access: yes, 2005
Financial support provided by the New Hampshire Estuaries Project (NHEP) to the City of Portsmouth helped with the cost of installing a new sewer line at Oxford Avenue that replaced the on-site subsurface disposal systems (septic systems) for fourteen ...

The development of low-emission public urban transport in Poland [PDF]

open access: yes, 2018
The aim of the paper is to identify the main factors and mechanisms behind the development of low-emission public transport vehicles in Polish cities. This innovation is primarily connected with growing environmental requirements for transport, with the ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Impact of Nitrogen Deposition on Carbon and Nitrogen Cycling in Peatlands Under Land‐Use Change

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Increasing nitrogen (N) deposition significantly alters carbon and N dynamics in peatlands by affecting microbial processes, enhancing greenhouse gas emissions and nutrient leaching into adjacent waters. However, how peatland conversion for agriculture and forestry influences the fate of added N under elevated atmospheric deposition remains ...

An investigation into differential lateral dispersion of fossil forest tree pollen [PDF]

open access: yes, 1974
Pollen rain phenomena with particular reference to forest pollen are discussed with evidence from FAEGRI.K and IVERSON.J, TAUBER.H, TURNER.J, and DAVIS .M. B. The existence of fossil tree pollen rain in raised bogs is postulated. The problem of local bog

A simple index for assessing cumulative human impacts on mountain lakes

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Defining Quality of Life: The Perspective of People Living with Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Little is known about how people with Parkinson's conceptualize “quality of life.” Objective To describe the meaning of “quality of life” from the perspective of people with Parkinson's. Methods Participants (N = 42) were asked “What does the term ‘quality of life’ mean to you?” Definitions were analyzed using inductive qualitative ...

The ability of contrasting ericaceous ecosystems to buffer nitrogen leaching [PDF]

open access: yesMires and Peat, 2013
Much attention has been given to the carbon balance of peatland and heathland ecosystems and their role as global carbon stores. They are also important as buffers for atmospheric nitrogen (N) pollution, locking N into the soil and vegetation through ...

Pinguicula brendae (Lentibulariaceae) sp. nov., a carnivorous plant from a tropical montane cloud forest in Hidalgo, Mexico

open access: yesNordic Journal of Botany, EarlyView.
A new species of Lentibulariaceae, Pinguicula brendae Rodríguez‐Ramírez, H.Shimai & A.R. Andrés‐Hernández, is described based on its unique morphological characteristics. This species is restricted to limestone rock walls in the San Bartolo Tutotepec municipality, central‐eastern Hidalgo, Mexico, where it inhabits a single locality on vertical, north ...

From geometric design to numerical analysis: A direct approach using the Finite Cell Method on Constructive Solid Geometry

open access: yes, 2017
During the last ten years, increasing efforts were made to improve and simplify the process from Computer Aided Design (CAD) modeling to a numerical simulation. It has been shown that the transition from one model to another, i.e.
