Sediment-dynamics modeling is a useful tool for estimating a dam's lifespan and its cost-benefit analysis. Collecting real data for sediment-dynamics analysis from conventional field survey methods is both tedious and expensive. Therefore, for most rivers, the historical record of data is either missing or not very detailed. Available data and existing tools have much potential and may be used for

A multicriteria framework is developed for the selection of optimal flood mitigation and river training measures in a selected reach of Zaremroud River in Northern Iran. A river model, Hydrologic Engineering Center River Analysis System, combined with geographic information system analysis is used to simulate water levels for steady, gradually varied flow and mapping inundated flood extents. The m

Med hjälp av ett automatiserat mätsystem för partikelhalter i vatten har vattenkvaliteten vid Borensbergs vattenverk i Motala kommun undersökts under ett års tid med avseende på mikroskopiska partiklar i dricksvatten och råvatten. Antalet mikroskopiska partiklar registrerades som absoluta värden i realtid. I denna artikel diskuteras hur larmgränser skall definieras i praktiken för partikelhalter oDuring a one year long research project at Borensberg Waterworks, Motala, Sweden, water quality with respect to microscopic particle counts both in raw water and drinking water have been monitored by an online water quality monitoring system. Microscopic particle counts were documented with absolute values in real-time. In this paper, a discussion is introduced on how to analyze large data sets fr

Background: Manganese (Mn) is an essential element but at excessive levels, it is neurotoxic. Even a moderate increase in Mn has been suggested to interfere with neurodevelopment in children. Genetics influencing Mn concentrations and toxicity is unclear. Objective: We assessed, in a cross-sectional study, whether common single-nucleotide polymorphisms in the Mn transporters SLC39A8 (influx) and S

Elevated concentrations of inorganic arsenic, one of the most potent environmental toxicants and carcinogens, have been detected in well water around Lake Poopó, Bolivia. This study aimed to assess human exposure to arsenic in villages around Lake Poopó, and also to elucidate whether the metabolism and detoxification of arsenic in this population is as efficient as previously indicated in other An

Cyanobacteria in fresh water can cause serious threats to drinking water supplies. Managing cyanobacterial blooms particularly at small drinking water treatment plants is challenging. Because large amount of cyanobacteria may cause clogging in the treatment process and various cyanotoxins are hard to remove, while they may cause severe health problems. There is lack of instructions of what cyanoba

Denna studie syftar till att preliminärt utvärdera förändringar i risken för cyanobakteriella blomningar i en eutrof sjö, Vombsjön, som ligger i södra Sverige och testa hur näringsämnen (fosfor och kväve) påverkar algväxten. Ytvatten som sjöar har stor betydelse för dricksvattenförsörjningen, till exempel hälften av dricksvattnet i Sverige är från ytvatten. Enligt riskmatrisen har Vombsjön en storThis study aims to preliminarily evaluate changes in the risk of cyanobacterial blooms in a eutrophic lake, Lake Vombsjön, in the southern Sweden and test the role of nutrients (phosphorus and nitrogen) in algae formation. Surface water such as lakes service great importance for drinking water supply, such as half of the drinking water in Sweden is from surface water. According to risk matrix, Lak

On average, five to six typhoons hit the Vietnamese coastline every year, often causing great destruction and many deaths as they move in over land. When a typhoon passes it brings high water levels, large waves, strong winds, and heavy rainfall. The high water levels, in combination with large waves, may induce overtopping and erosion of dikes and sand dunes. This can lead to flooding and saltwat

The Swedish coast is dominated by rock shorelines (Bird, 1985; Bird and Schwartz 1985). Sand beaches are primarily found in the southern part (Lindh et al., 1970; Rydell et al., 2004), mainly in the county of Scania (Figure 3.1) but also to some extent in Halland, located on the Swedish west coast just above Scania. In Scania, sand constitutes the major source of material along about 200 km of sho

Public Diplomacy has assumed great significance in foreign policy and strategic communication for Rising Powers like India and China. These Rising nation-states, with expanding economies and global ambitions, are taking to purposeful communication with global audiences for building positive image and enhancing goodwill. In such efforts, the use of social media has become extensive and widespread.

Matagorda Peninsula and Sargent Beach, Texas, USA, have experienced some of the highest rates of erosion along the Texas coast. In order to increase protection from tropical events and slow beach habitat erosion, several structural alternatives were studied. These alternatives were modeled with GenCade, a newly developed 1D shoreline change and sand transport model. GenCade was calibrated and vali

A new numerical model of regional sediment transport and barrier elongation, supplied by sediment coming from longshore sediment transport (LST), was developed. The spit growth and barrier elongation model was based on the model proposed by Kraus (1999). The LST rate used as input for the spit growth and barrier elongation model was simulated by the one-line model of shoreline change (Hanson, 1987

In 2005, US Marines killed 24 unarmed Iraqi civilians in the town of Haditha, including several children. How should we assess the perpetrators of this and other war crimes? Is it unfair to blame the Marines because they were subject to situational pressures such as combat stress (and had lost one of their own in combat)? Or should they be held responsible for their actions, since they intentional

The militarized response to the rhino poaching crisis in southern Africa exposes poachers to “fatal couplings of power and difference” (Gilmore 2002). While the racialized dimensions of this phenomenon are currently the subject of robust debate, this paper focuses on how race, gender, and sexuality are co-constructed in the anti-poaching discourse. Bringing the work of geographer Ruth Wilson Gilmo

In this chapter it is argued that Mary Wollstonecraft’s political is best characterized as ‘feminist republicanism’. Wollstonecraft’s feminism challenges republicanism from within. The republican movement used the language of rights and liberty in arguments for popular sovereignty and against despotic and aristocratic privilege. Wollstonecraft articulated her feminism within and against this movem

It is my contention here that Quentin Skinner’s conception of neo-roman liberty as it is articulated in Liberty Before Liberalism serves to establish two normative premises for human rights philosophy. Those premises are, first, that human rights should offer the strongest protection for those persons who are most vulnerable and liable to social and political discrimination and marginalisation. Se
