In this work H-1 NMR self-diffusion experiments have been performed to determine the self-diffusion coefficients of n-octyl beta-D-glucoside and n-nonyl beta-D-glucoside in alpha-cyclodextrin and beta-cyclodextrin solutions at 25 degreesC. Two questions are addressed. The first concerns the general influence on nonionic surfactant transport properties when cyclodextrins are present in solution. Th
An accurate and variationally consistent 4-node quadrilateral element is introduced where high coarse mesh accuracy and low mesh distortion sensitivity are characteristic qualities, even when incompressibility is approached for plane strain. One-point quadrature integration procedure is adopted and a new improved stabilization technique is developed. Orthogonality conditions are utilized so that t
The growth of iron phthalocyanine (FePc) on InSb(001) c(8 x 2) at submonolayer coverage has been investigated with scanning tunneling microscopy (STM). FePc adsorbs flat centered on the In rows both at 70 K and at room temperature (RT). However, the shapes of the two-dimensional molecular islands are fundamentally different; while the RT growth results in chainlike structures along the [I 10] dire
In this paper we derive several important results towards a better understanding of propagation characteristics of resilient Boolean functions. We first introduce a new upper bound on nonlinearity of a given resilient function depending on the propagation criterion. We later show that a large class of resilient functions admit a linear structure; more generally, we exhibit some divisibility proper
The objective of this study was to investigate the feasibility of the Aerodynamic Particle Sizer (APS) and the Electrical Low-Pressure Impactor (ELPI) to study mass weighted particle size distributions. Unimodal and bimodal liquid test aerosols were produced to a small chamber. Simultaneous measurements were performed with an APS 3320, an APS 3321, an ELPI and a Dekati Low-Pressure Impactor (DLPI)
The ultrastructure of embryonic chick cartilage proteoglycan core protein was investigated by electron microscopy of specimens prepared by low angle shadowing. The molecular images demonstrated a morphological substructural arrangement of three globular and two linear regions within each core protein. The internal globular region (G2) was separated from two terminally located globular regions (G1
The extracellular matrix molecule tenascin-R (TN-R) and the proteoglycans of the lectican family show an overlapping distribution in the developing brain, have been implicated in similar cellular processes and form a complex network of interactions. Previously, we have demonstrated that TN-R induces microprocesses along neurites and enlarged growth cones of tectal cells by interacting with the cel
In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis,

onthly averages of ecosystem respiration (ER), gross primary production (GPP) and net ecosystem exchange (NEE) over Scandinavian forest sites were estimated using regression models driven by air temperature (AT), absorbed photosynthetically active radiation (APAR) and vegetation indices. The models were constructed and evaluated using satellite data from Terra/MODIS and measured data collected at
Objective: High levels of sex steroid hormones and prolactin have been suggested to enhance breast cancer development. Low levels of SHBG may indicate high levels of (bio-available) steroid hormones. The present study investigates whether high levels of sex steroid hormones and prolactin, and/or low levels of SHBG, are associated with high breast cancer risk. Methods: Blood samples were collected
In guinea-pig isolated airways, nonadrenergic, noncholinergic (NANC) neural responses converge towards a similar level of smooth muscle tone, via a contraction when the tone is low prior to stimulation, and via a relaxation when the tone is high prior to stimulation. We wanted to assess the effect of simultaneous parasympathetic activation on these converging NANC responses, with and without the a
The gamma decay of excited states in the N = Z odd-odd nucleus Rb-74 has been observed for the first time. The reaction Ca-40(Ca-40,alpha pn)Rb-74 at 128 MeV beam energy was used. The ground state rotational band can be interpreted as being formed from the T = 1 isobaric analog states of Kr-74 with pairing correlations based on T = 1, M(T) = 0 neutron-proton pairs. At higher rotational frequency,
The possibility of recording changes in electroencephalography potentials following perception of sound was reported several decades ago. The recent expanding research on auditory cortical event-retated potentials (AERPs) for assessing sound discrimination abilities in children and infants has indicated that several methodological issues need to be addressed before it can be implemented in clinica
