Gaza has several water problems; limited fresh water supply, inefficient water use by the agricultural sector, high water demand, groundwater contamination, seawater intrusion and shortage of electricity. Water and electricity is the first priority for Gaza that will add significant positive values to the Palestinians living in blocked Gaza and easy operation and maintenance of their ongoing and e
We present a widely scalable, high temperature post-growth annealing method for converting ultra-thin films of TiO2 grown by atomic layer deposition to topographically microstructured titanium silicide (TiSi). The photoemission electron microscopy results reveal that the transformation from TiO2 to TiSi at 950 °C proceeds via island formation. Inside the islands, TiO2 reduction and Si diffusion pl
Hierarchical polymer structures such as pNIPAM microgels have been extensively studied for their ability to undergo structural and physical transformations that can be controlled by external stimuli such as temperature, pH or solvent composition. However, a direct three-dimensional visualization of individual particles in-situ has so far been hindered by insufficient resolution, with optical micro
This article examines smallholders’ perceptions of climate variability in two districts in Northern Ethiopia, and the diversification options pursued within and outside agriculture. Meteorological records corroborate smallholders’ belief that temperatures are increasing but do not support assertions that rainfall is decreasing. Farm-level adaptation mainly involves soil and water conservation meas
This project offers an initial evaluation of using the online learning platform Prezi as a tool for increasing student learning within a MA unit in human geography. It does this by comparing the use of Prezi to four other learning activities conducted during the course. The aim of the project is to see whether the use of this technology became an end in itself, thereby distracting students and det
Denna avhandling studerar den moraliska konfliktlinje som genomsyrade den frihetstida politiken åren kring 1740 och som strukturerade politiken enligt en särskilt moralpolitisk logik. Logiken hade sin grund i dels samhällsordningens absoluta och normativt oföränderliga karaktär, dels ett antal djupa förmoderna erfarenheter av och förväntningar på människan som oförmögen att hantera sin fördärvade This thesis examines the moral conflict permeating the politics of Sweden’s Age of Liberty around 1740 – a conflict that also structured the politics of the time in relation to a particular political logic based on moral. This logic was based on the absolute and normatively immutable nature of the social order, but also on a number of deep pre-modern experiences and expectations of man as unable t
Summary The egress strategy in high-rise buildings has traditionally been based on the sole use of stairs for evacuation. However, it is becoming more common to include evacuation elevators in the egress strategy in high-rise buildings. Traditionally, evacuation elevators have not been allowed as an evacuation route, and people have been instructed to not use elevators in case of fire. This means
Recent studies suggest that increases in extent and duration of winter soil frost increases dissolved organic carbon (DOC) concentrations in boreal riparian soils and connected aquatic systems during the subsequent spring and summer. However, little is known about the impact of frost on DOC character and its degradability. We applied three experimental treatments to riparian soils in northern Swed
Although training and development is recognized as an important means to nurture corporate entrepreneurs in organizations, extant research has focused primarily on efforts to develop entrepreneurial leaders and nurture business creation in a school or university setting. We report on the findings of an inductive case study of corporate entrepreneurship training in a large multinational corporation
Tumors are complex entities, composed of different functional populations of malignant and stromal cells. There is an emerging importance to understand previously unmapped communication routes between different cell and non-cell compartments of the tumor microenvironment. Targeted drugs have been used for years in an attempt to block essential pathways for tumor growth. Specifically, drugs targeti
This comparative case study of three Asian cities (Penghu in Taiwan, Seoul in South Korea and Tianjin in China) elucidates the effects of different national approaches to eco-city development and the antecedents of the building of an eco-city. To better understand the Asian context, the three Asian cities of interest were compared with two European cities - Freiburg (Germany) and Samsö (Denmark).
Wildfire has become a major disturbance agent in Mediterranean area, with Galicia in the north-west of Spain having the most frequent fires. In order to combat soil erosion, different post-fire stabilization treatments can be applied, like adding different mulch materials. In a laboratory experiment we evaluated the effect of adding plant residues, commonly used in post-fire rehabilitation (wheat
Introduction: Giant-cell tumor of bone (GCTB) is a locally aggressive histologically benign neoplasm with a less common malignant counterpart. Longitudinal data sources on GCTB are sparse, limited to single institution case series or surgical outcomes studies. The Swedish Cancer Registry is one of the few national population-based databases recording GCTB, representing a unique source to study GCT
Current European regulations on producer responsibility provide limited incentives for ecodesign practices among manufacturers. Additional incentives for 'design for resource efficiency' and 'design for recycling' could be provided through mandatory design standards set under the Ecodesign Directive. While European manufacturers have become increasingly positive towards eco-design standards for en
Previous reports have connected non-symbiotic and truncated hemoglobins (Hbs) to metabolism of nitric oxide (NO), an important signalling molecule involved in wood formation. We have studied the capability of poplar (Populus tremula × tremuloides) Hbs PttHb1 and PttTrHb proteins alone or with a flavin-protein reductase to relieve NO cytotoxicity in living cells. Complementation tests in a Hb-defic
Purpose: Children who have a parent with incurable cancer are in a vulnerable situation and the Swedish law tries to protect them. This article aims to explore the interactions between nurses and children of patients with incurable cancer from the nurses' perspective. Method: Semi-structured interviews with nine nurses in palliative oncology in Southern Sweden. Latent content analysis was carried
Italian novelist Italo Calvino ([1972] 1974: 102–103) described Leonia as a city where ‘every morning the people wake between fresh sheets, wash with just-unwrapped cakes of soap, wear brand-new clothing, take from the latest model refrigerator still unopened tins, listening to the last-minute jingles from the most up-to-date radio’. This opulent newness is dependent upon garbage trucks collecting
This paper adds to the relatively few European studies on the pedestrian friendliness of urban areas, and on transport walking. Using the Human Environment Interaction (HEI) model (Küller, 1991), the study explores the associations between perceived neighbourhood spatialphysical and social environment qualities and walking to neighbourhood destinations, and examines whether these associations are
This article introduces the notion of sustainability objects as a label for objects that come with a claim of promoting a more sustainable mode of living. The purpose is to show that organizations that develop such objects construct a performative definition of sustainability. A case study of the development of a facility for the pre-treatment of food-waste-based biogas and biofertilizers serves a
The increasing importance being placed on waste prevention in European waste governance raises the question of how waste prevention is defined in practice. This paper presents a qualitative analysis of a sample of fifty-one Swedish waste prevention initiatives with the purpose of identifying which kind of actions are imagined, promoted, and set into motion under the label of waste prevention. The
