Intensive agricultural practices can dramatically change the landscape, thereby increasing the concentrations and rates at which nutrients are delivered to aquatic ecosystems. In the United States, concerns about accelerating rates of lake eutrophication related to increases in nutrient loading require a method of quantifying ecological changes that have occurred since European settlement. Because
We have examined the timing of calling behavior in the female Egyptian cotton leafworm, Spodoptera littoralis and its modification by exposure to sex pheromone. The calling rhythm of the female moth was found to be circadian, persistent for at least 4days once it has been entrained, and could be phase shifted by altering the light:dark regime. We also found that female exposure to pheromone affect
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy encountered in diabetes. The short-term improvement after carpal tunnel release has previously been demonstrated not to differ between patients with and without diabetes, despite a marked impairment in health-related quality of life (HRQL) among the former. In this study, we compare HRQL 5 years after carpal tunnel release betwe
Purpose - The article has two major purposes. The first purpose is to examine the roles and practices of communication professionals in relation to internal aspects of crisis communication. The second purpose is to suggest new roles and practices for communication professionals that will enable a strategic approach to internal crisis communication. This article is based on empirical material from
Background: Plasmodium falciparum EBA175 and PfRh2 belong to two main families involved in parasite invasion, and both are potential vaccine candidates. Current knowledge is limited regarding which target antigens and subclasses of antibodies are actually important for protection, and how naturally acquired immunity is achieved. Methods: Repeated blood samples were collected from individuals in Ni
The classical Kalman-Yakubovich-Popov lemma gives conditions for solvability of a certain inequality in terms of a symmetric matrix. The lemma has numerous applications in systems theory and control. Recently, it has been shown that for positive systems, important versions of the lemma can equivalently be stated in terms of a diagonal matrix rather than a general symmetric one. This paper generali
Popular Abstract in Swedish Hur kan svenska myndigheter förbereda sig för att hantera nästa kris när det gäller tillgängligheten av deras mest kritiska informationssystem? Det är den centrala frågan i denna avhandling. Svenska myndigheter och kommuner har en central roll i det svenska krishanteringssystemet. Givetvis är svenska kommunala och statliga verksamheter väldigt beroende av IT-system. SjAs our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. This is especially true for systems that are critical in a crisis situation and whose dependability is an important factor in an organisation's capability to resolve a crisis. Because crisis situations are typically rare events, both the dependability and the criticality of IT sys
Habitat area is an important predictor of spatial variation in animal densities. However, the area often correlates with the quantity of resources within habitats, complicating our understanding of the factors shaping animal distributions. We addressed this problem by investigating densities of insect herbivores in habitat patches with a constant area but varying numbers of plants. Using a mathema
In this study, we validated comfort and limit temperatures of four sleeping bags with different levels of insulation defined according to EN 13537. Six male subjects and four female subjects underwent totally 20 two-hour exposures in four sleeping bags at four intended testing temperatures: 11.2, 3.8, 2.1 and -9.0 degrees C. The subjective perceptions and physiological responses of these subjects
In the study reported here we examined the short-term effects (1-3 years) of slash retention (SR) and the long-term effects (13-15 years) of wood-ash application (A) on fine roots and mycorrhizae in a 40-year-old Norway spruce forest in southwest Sweden. Soil cores were used to obtain estimates of the biomass (g m(-2)) of roots in three diameter classes (< 0.5, 0.5-1 and 1-2 mm), root length densi
Removal of disease-driving inflammatory leucocytes is central to resolution of inflammation. The current pharmacological dogma teaches leucocyte elimination through apoptosis followed by phagocytosis. However, actual resolving roles of apoptotic-phagocytic processes have been difficult to demonstrate in the major diseases that are characterized by mucosal tissue inflammation. Many current in vivo
Two centrosymmetric dinuclear nickel(II) complexes, [Ni-2(dmpn)(2)(hap)(2)(mu(1,1)-N-3)(2)] and [Ni-2(dmpn)(2)(hap)(2)(mu(1,1)-N-3)(2)], (dmpn=N,N-dimethyl-1,3-diaminopropane and Hhap = 2-hydroxyacetophenone, Hhan = 1-hydroxy-2-acetonaphthone) have been synthesized and characterized. Single crystal X-ray diffraction analyses confirm the structures of one of the tridentate Schiff bases used and bot
In this paper, we describe the synthesis of water-compatible Molecularly Imprinted Polymer (MIP) microspheres by nanoparticle-stabilized emulsion (Pickering emulsion) polymerization. During the polymerization, the amount of the porogen used not only affected the stability of the Pickering emulsion but also the specific molecular recognition of the obtained MIP microspheres. Under optimized conditi
A novel algorithm for the detection of fixations and smooth pursuit movements in high-speed eye-tracking data is proposed, which uses a three-stage procedure to divide the intersaccadic intervals intoa sequence of fixation and smooth pursuit events. The first stage performs a preliminary segmentationwhile the latter two stages evaluate the characteristics of each such segment and reorganize the pr
