Aim: Several studies have addressed the association between changes in the female sex hormones estrogen and progesterone levels and changes in parameters of periodontitis. In order to understand how these hormones affect periodontal health it is of major importance to obtain information on their physiological importance. We have previously shown that periodontal ligament cells (PDL cells) express
Advanced 1-D models for Secondary Settling Tanks (SSTs) explicitly account for several phenomena that influence the settling process (such as hindered settling and compression settling). For each of these phenomena a valid mathematical expression needs to be selected and its parameters calibrated to obtain a model that can be used for operation and control. This is, however, a challenging task as
An efficient method to form 3D superlattices of gold nanoparticles inside oil emulsion droplets is presented. We demonstrate that this method relies on Ostwald ripening, a well-known phenomenon occurring during the aging of emulsions. The key point is that the nanoparticle concentration inside the smaller droplets is increasing very slowly with time, thus inducing the crystallization of the nanopa
To search for an S = -1 di-baryonic state which decays toΛp, the 3He(K-,Λp)nmissing reaction was studied at 1.0 GeV/c. Unobserved neutrons were kinematically identified from the missing mass MX of the 3He (K-,Λp) X reaction in order to have a large acceptance for the Λpn final state. The observed Λpn events, distributed widely over the kinematically allowed region of the Dalitz plot, establish tha
Carbon fiber reinforced plastics, CFRP, are attractive materials not only because of their strength and stiffness but also because of their electrical conductivity and high thermal conductivity and diffusivity. One application where induction heating of CFRP is particularly interesting is tools for fast thermal cycling, beneficial inmany industrial processes, for example in composite manufacturingCarbon fiber reinforced plastics, CFRP, are attractive materials not only because of their strength and stiffness but also because of their electrical conductivity and high thermal conductivity and diffusivity.

Maritime operations are complex socio-technical activities, with many interacting agents. Such agents are acting based on different, sometimes conflicting, goals. The traditional approach for safety, based on decomposition and bimodality, might lead to ineffective analyses, ignoring the transient and hidden links among activities as they are performed in everyday work. In this sense, the Functiona
Popular AbstractStörre kriser och katastrofer som stormen Gudrun och dess konsekvenser är sannolikt att vänta i framtiden. Det råder dock ovisshet om vilka kriserna kommer att vara och under vilka förutsättningar. Nya och kompletterande vetenskapliga studier och metoder inom kris- och katastrofforskningen måste till för att öka samhällets kunskap om och förmåga att hantera kända och okända hotbildSevere crises and disasters such as the Hurricane Gudrun and their consequences will probably occur in the future. However, there are many uncertainties concerning disasters and their effects. New scientific approaches and methods for crisis and disaster research must be developed to increase the knowledge and ability of societies to manage known and unknown threats. Substantial research on the em
A common floor construction in a lightweight building system is using chipboard plates attached to wooden beams using screws and glue. One drawback with such a system is the propagation of vibrations stemming either from harmonic (washing machines, dishwashers, HiFi-systems) especially at low frequencies and/or transient (Human walking, dropped items, slamming doors) excitations. In order to accur
In this paper we develop an Enterprise Systems Implementation Methodology in Action framework. The framework is grounded in contemporary views on methodology in action (theoretical grounding) and enhanced by an empirical study (empirical grounding). The notion of Implementation Methodology in Action, as articulated in this paper, integrates two complementary views that conceptualise a methodology
Major databases on western clothing and their thermal properties are available, but information on non-western clothing is lacking. A recent ASHRAE project 1504 TRP, Extension of the Clothing Insulation Database for Standard 55 and ISO 7730 dealt with the issue. Simultaneously, a co-operation study at Indian workplaces allowed us to acquire some sets of the traditional clothes used at construction
Introduction: Sudden cardiac death (SCD) and early onset cardiomyopathy (CM) in the young will always lead to suspicion of an underlying genetic disorder. Incited by the rapid advances in genetic testing for disease we have revisited families, which previously tested “gene-negative” for familial predominantly pediatric CM, in hopes of finding a causative gene variant. Methods: 10 different familie
The behaviour and function of dynamic samples can be investigated using optical imaging approaches with high temporal resolution and multidimensional acquisition. Snapshot techniques have been developed in order to meet these demands, however they are often designed to study a specific parameter, such as spectral properties, limiting their applicability. Here we present and demonstrate a frequency
In its judgment in International Stem Cell Corporation v Comptroller General of Patents (ISCO) rendered on 18th December 2014, the CJEU qualified its’ earlier ruling in Brüstle v. Greenpeace (Brüstle) with regard to non-fertilised human ovums stimulated by parthenogenesis. The Court held that in order to constitute a ‘human embryo’ and thus to be unpatentable under the EU Biotechnology Directive,
Background: Legislation was passed in Sweden to stimulate the development of different housing solutions for persons suffering from severe mental illness. Among these solutions are small congregate residences built in the community to provide suitable housing and support for those not able or willing to live independently. Aims: The general aim of the present study was to compare the psychosocial
