Lean construction principles have been successfully adopted in a variety of industries to increase project management quality. This paper addresses maintenance planning in Sweden and analyses its effectiveness in the framework of lean construction principles. To investigate the status and improvement potential of maintenance contractors’ performance, the study focuses on the detailed planning proc
We present a statistical framework to identify regional signals in station-based CO2 time series with minimal local influence. A curve-fitting function is first applied to the detrended time series to derive a harmonic describing the annual CO2 cycle. We then combine a polynomial fit to the data with a short-term residual filter to estimate the smoothed cycle and define a seasonally adjusted noise
The synthesis of high-value fuels and plastics starting from small hydrocarbon molecules plays a central role in the current transition towards renewable energy. However, the detailed mechanisms driving the growth of hydrocarbon chains remain to a large extent unknown. Here we investigated the formation of hydrocarbon chains resulting from acetylene polymerization on a Ni(111) model catalyst surfa
The influence of the Sc cation substituent on the structural and luminescence properties of GAGG:Ce crystals was studied. Unit cell parameters and space groups were obtained using XRD analysis. The chemical compositions of the crystals were determined using SEM-EDX and TEM-EDX techniques. Structures were refined by the Rietveld method and the distribution of Al/Ga/Sc cations between octahedral and
The parameters relevant for prediction of service lifetime with respect to chloride ingress are associated with large uncertainties. Full-scale measurements are in demand for conditions which are as homogeneous as possible. The present paper first summarizes statistical distributions which are obtained based on measurements from the Gimsøystraumen bridge in Norway. These probability distributions
Biological rhythms of nearly all animals on earth are synchronized with natural light and are aligned to day-and-night transitions. Here, we test the hypothesis that the lunar cycle affects the nocturnal flight activity of European Nightjars (Caprimulgus europaeus). We describe daily activity patterns of individuals from three different countries across a wide geographic area, during two discrete
Aquaporins are protein channels embedded in the lipid bilayer in cells from all organisms on earth that are crucial for water homeostasis. In fish, aquaporins are believed to be important for osmoregulation; however, the molecular mechanism behind this is poorly understood. Here, we present the first structural and functional characterization of a fish aquaporin; cpAQP1aa from the fresh water fish
he history and legacy of green planning of the welfare era have largely been overlooked within research, or critiqued due to its limited urban qualities and poor design. This omission has left its role in the development of the Welfare society largely unexplored. Therefore, this special issue revisits the green geographies of welfare planning, to reveal its importance as a matter of welfare and as
The new metastable high-pressure high-temperature synthesized hexagonal Laves phase compound YbZn2 was investigated. The unit cell parameters, low-temperature Sommerfeld coefficient and Debye temperature were determined. X-ray absorption studies and calculations based on dynamical mean-field theory (DMFT) showed the intermediate valence behavior of YbZn2 with mean Yb valence about 2.55. The values
Mutations in mitochondrial D-loop region of DNA (mtDNA) may serve as a potential sensor for cellular DNA damage and marker for cancer development. We investigated the restriction fragment length polymorphism (RFLP) pattern of the D-loop region in the blood samples of breast cancer patients among Mizoram population. Significant differences were observed among breast cancer and healthy blood samples
Contemporary social and cultural conditions in Brazil, together with technological developments and social media have enabled more young people of the favela to participate in different spheres of public life. These social and cultural changes have brought diversified new images of what it means to be an embodied subject. In this article, I explore the ways in which the body holds a seemingly para
A gendered reading of the liberal peacebuilding and transitional justice project in Bosnia–Herzegovina raises critical questions concerning the quality of the peace one hopes to achieve in transitional societies. By focusing on three-gendered justice gaps—the accountability, acknowledgement, and reparations gaps—this article examines structural constraints for women to engage in shaping and implem
