Tendenser och trender i tidskriften Vattens artiklar under 75 år

The Journal of Water Management and Research (Vatten) celebrates 2019 its 75th anniversary with a special issue, republishing one article per decade from 1940 to 2010. In the present article, we summarize the development of Swedish water research and management based upon the material published in the journal. We read all issues of the journal, noting important trends, percentage of female authors

Projectification of sustainable development: implications from a critical review

Purpose In this paper, the authors challenge traditional views of project management and sustainable development as purportedly complementing each other. Rather, the authors apply a projectification perspective from a multi-disciplinary approach to sustainable development. The purpose of this paper is to demonstrate how we can better understand the interface between projects and sustainable develo

The cyclic peptide labaditin does not alter the outer membrane integrity of Salmonella enterica serovar Typhimurium

Antimicrobial peptides are a promising class of new antibiotics with the ability to kill bacteria by disrupting their cell membrane, which is especially difficult for Gram-negative bacteria whose cell wall contains an outer layer of lipopolysaccharides (LPS). Here we show that the cyclic decapeptide Labaditin (Lo), with proven activity against the Gram-positive Staphylococcus aureus and Streptococ

Experimental evidence for the mode of action based on electrostatic and hydrophobic forces to explain interaction between chitosans and phospholipid Langmuir monolayers

The interaction between chitosans and Langmuir monolayers mimicking cell membranes has been explained with an empirical scheme based on electrostatic and hydrophobic forces, but so far this has been tested only for dimyristoyl phosphatidic acid (DMPA). In this paper, we show that the mode of action in such a scheme is also valid for dipalmitoyl phosphatidyl choline (DPPC) and dipalmitoyl phosphati

Study of the interaction between cardiolipin bilayers and methylene blue in polymer-based Layer-by-Layer and Langmuir films applied as membrane mimetic systems

An increase of the reports involving mimetic systems has been observed. Briefly, these systems use biological phospholipids to exploit specific interactions between membrane-models and drugs. Here, the Layer-by-Layer (LbL) and Langmuir techniques were used to investigate the interaction between cardiolipin (CLP - negative phospholipid) and a cationic-like drug methylene blue (MB). Supported by a c

Structural and electric-optical properties of zinc phthalocyanine evaporated thin films : Temperature and thickness effects

It is known that the molecular architecture plays a fundamental role in the electrical and optical properties of materials processed in the form of thin films. Here, zinc phthalocyanine (ZnPc) thin films were fabricated through the vacuum thermal evaporation technique (PVD, physical vapor deposition) up to 50 nm thickness with the objective of determining their molecular architecture and some elec

Beyond Ethnographic Representation

This chapter deals with ways in which digital technologies can be utilized to work with moving media in hybrid ways. It will resonate with practices of ethnographic film, but it will also attempt to move beyond traditional, representational notions of this practice, very much in line with the ideas of the “new world of ethnographic film and video” that Phillip Vannini outlines in the introduction

Ventilation with increased apparatus dead space vs positive end-expiratory pressure : Effects on gas exchange and circulation during anesthesia in a randomized clinical study

Atelectasis formation can be reduced by positive endexpiratory pressure (PEEP), but resulting increases in intrathoracic pressure could affect circulation. We have earlier demonstrated that increased tidal volumes with larger apparatus dead space improves oxygenation and sevoflurane uptake. In the present study, we hypothesize that isocapnic ventilation with increased tidal volumes increases oxyge

Klimatförändringars inverkan på broars säkerhet och prestanda : En översyn av potentiella effekter och anpassningsåtgärder

4 Sammanfattning Vår infrastruktur kommer att påverkas av klimatförändringar, både nu och i framtiden. För att kunna säkerställa infrastrukturens funktion och uppfylla de säkerhetskrav som finns kommer det därför att krävas investeringar i anpassningsåtgärder. Men åtgärder bör inte tas på utifrån bristfällig kunskap, det är därför väsentligt att i förväg kartlägga vilka typer av påverkan som kan f

Experimental and theoretical lifetimes in Yb III

Lifetimes of three levels belonging to the configuration 4f135d with J = 1 in Yb III have been measured for the first time using the time-resolved laser-induced fluorescence method. Experimental transition probabilities have been deduced for the transitions between the levels studied and the ground state. The comparison of the experimental lifetimes with theoretical data, deduced within the relati

Hippocampal vascularization patterns : A high-resolution 7 Tesla time-of-flight magnetic resonance angiography study

Considerable evidence suggests a close relationship between vascular and degenerative pathology in the human hippocampus. Due to the intrinsic fragility of its vascular network, the hippocampus appears less able to cope with hypoperfusion and anoxia than other cortical areas. Although hippocampal blood supply is generally provided by the collateral branches of the posterior cerebral artery (PCA) a

We have reviewed studies investigating the effect of physical activity on prevention of early age-related macular degeneration (AMD), progression to late AMD, and risk modulation of morbidity and mortality in patients with AMD. Regular physical activity may lower risk of developing early AMD and progression of early AMD to late AMD at a level comparable with smoking cessation or dietary supplement

In patients with neovascular age-related macular degeneration, physical activity may influence C-reactive protein levels

PURPOSE: Association of neovascular age-related macular degeneration (AMD) with C-reactive protein (CRP) was previously reported, indicating a relation to systemic low-grade inflammation. However, visual impairment limits physical activity, and physical activity modulates CRP levels. Here, we investigated the impact of physical activity on CRP levels in patients with neovascular AMD and control in

Age-related macular degeneration is associated with increased proportion of CD56(+) T cells in peripheral blood

PURPOSE: To examine the association between age-related changes in the T-cell compartment and prevalence of age-related macular degeneration (AMD).DESIGN: Case-control study.PARTICIPANTS: A total of 117 AMD cases and 106 controls were included prospectively.METHODS: Fresh-drawn peripheral blood samples were processed for flow cytometric analysis of T-cell populations. Plasma samples were analyzed
