Denna rapport behandlar fuktskador i ett hus uppfört 1973 med platta på mark och flytande golv. Mätningar har genomförts i huset under två år. Syftet var att erhålla mätdata under en lång tidsperiod i en byggnad med klara fukt- och luktproblem. I rapporten diskuteras lämpliga åtgärder för att komma till rätta med problemen.
In this study, we show that distinct compartmentalization patterns of the IL-1 molecules (IL-1alpha and IL-1beta), in the milieu of tumor cells that produce them, differentially affect the malignant process. Active forms of IL-1, namely precursor IL-1alpha (pIL-1alpha), mature IL-1beta (mIL-1beta), and mIL-1beta fused to a signal sequence (ssIL-1beta), were transfected into an established fibrosar
Context: T-3 action in neurons is essential for brain development. Recent evidence indicates that monocarboxylate transporter 8 (MCT8) is important for neuronal T-3 uptake. Hemizygous mutations have been identified in the X-linked MCT8 gene in boys with severe psychomotor retardation and elevated serum T-3 levels. Objective: The objective of this study was to determine the functional consequences
Fast line relaying algorithms are motivated by the need to keep the fault clearing time as short as possible. Fast fault clearing reduces the risk for transient instability, thermal stress on equipment and risk for personnel injuries. There exists, at least, three different themes in transmission line protection: impedance algorithms differential equation algorithms (DEA); and travelling wave algo
Problem med mikrobiell påväxt på fasader har ökat kraftigt på senare tid. Redan något år efter putsningen av en fasad har kraftig påväxt kunnat konstateras. En pilotstudie har genomförts av LTH i samverkan med JM AB och NCC Teknik, med stöd av SBUF och den visar att mögelpåväxten har samband med t ex fasadens utformning, ytans struktur, väggens värmeisolering och framför allt dess värmekapacitet.
Cubomedusae, or box jellyfish, have the most elaborate visual system of all cnidarians. They have 24 eyes of four morphological types, distributed on four sensory structures called rhopalia. Box jellyfish also display complex, probably visually guided behaviors such as obstacle avoidance and fast directional swimming. Here we describe the strikingly complex and partially bilaterally symmetrical ne
We analyzed the reactivity of three different commercially available rat monoclonal antibodies raised against mouse laminin-a1 beta 1 gamma 1 (laminin-11), AL-1, AL-2, and AL-4. Using ELISA assays, Western blot analysis and inummostainings we present refined epitope maps for these three laminin monoclonals. AL-1 reacted, as predicted with laminin alpha 1 chain. AL-4 has also been marketed as an al
Endoglucanases (EGI) (endo-1,4-β-d-glucan-4-glucanohydrolase, EC 3.2.1.4, Cel7B) of Trichoderma reesei are industrially important enzymes. Thus, there is a great need for development of a primary recovery method suitable for large-scale utilization. In this study we present a concept applicable for large-scale purification of an EGI fusion protein by one-step extraction in a poly(ethylene glycol)
We analyze the impact of the matching network on compact multiple-input multiple-output systems. Existing studies have found that the matching network has a significant influence on the performance of multiple antenna systems when the antennas are in close proximity. However, none has examined the wide-band case. In this paper, we investigate the wide-band performance of four different matching ne
My thesis is an attempt to give a minimalist account of word formation in Swedish. (See Chomsky (1993) and (1994).) In the main part of my thesis I demonstrate how the proposed system accounts for the central aspects of Swedish word formation. Simple words, compounds, and derivations alike are described as formed by Generalized Transformations, primarily by Merge, but also by Move. From a lexicon
A series of proteins and one membrane-bound peptide have been partitioned in aqueous two-phase systems consisting of micelle-forming block copolymers from the family of Pluronic block copolymers as one polymer component and dextran T500 as the other component. The Pluronic molecule is a triblock copolymer of the type PEO-PPO-PEO, where PEO and PPO are poly(ethylene oxide) and poly(propylene oxide)
Previously the screening of tropical plants demonstrated a high peroxidase activity in sweet potato (Ipomoea batatas) tubers. The major peroxidase pool is localized in peel. Using peel of sweet potato as a source, the sweet potato peroxidase (SPP) has been isolated and purified to homogeneity. The enzyme purification included homogenization, extraction of colored compounds and consecutive chromato
Molecular engineering of ligand-binding proteins is commonly used for identification of variants that display novel specificities. Using this approach to introduce novel specificities into CBMs (carbohydrate-binding modules) has not been extensively explored. Here, we report the engineering of a CBM, CBM42 from the Rhodothermits marinus xylanase Xyn10A, and the identification of the X-2 variant. A
The clinical course in urinary bladder cancer is difficult or impossible to predict based on conventional disease parameters. It is a reasonable hypothesis that the genetic aberrations acquired by the tumor cells, being instrumental in bringing about the disease in the first place, may also hold the key to more reliable prognostication. However, though 200 transitional cell carcinomas (TCC), the m
Rhizotrons provide valuable information about plant root production, but measurements are usually made in units of root length per unit surface area of observation window surface. These measurement units are not easily comparable to above-ground plant growth. To address this deficiency, several techniques have been developed to convert rhizotron measurement units into root mass production per unit
The complement protein C4 exists as two isotypes, C4A and C4B, encoded by genes in the major histocompatibility complex (MHC) class III region. The serum concentrations of C4A4 were lower than those of C4B2 in serum from 19 individuals homozygous for type I C2 deficiency (p < 0.0002). These individuals all had the S042 complotype and most of them were homozygous for the haplotype HLA-B18,S042,DR2.
Background: Foetal inflammation is associated with an increased risk of brain damage in preterm infants whereas IGF-I is essential for cerebral development and exhibits anti-apoptotic properties. Aim: To assess levels of IGF-I and IGF binding proteins at very preterm birth and to evaluate their relationship with foetal pro-inflammation and cerebral damage. Methods: Levels of IGF-I, IGF binding pro
This article emphasizes the continuities rather than the discontinuities between war and peace, suggesting that warfare as well as the making of peace can be seen as parts of a continuous bargaining process. It presents an analytical framework for past-war bargaining proceeding from four challenges which affect the balance between cooperation and conflict: (1) the timing of war endings; (2) leader
In sunshine, the Vikings navigated on the open sea using sundials. According to a widespread hypothesis, when the Sun was occluded by fog or clouds the Vikings might have navigated by skylight polarization detected with an enigmatic birefringent crystal (sunstone). There are two atmospheric optical prerequisites for this alleged polarimetric Viking navigation under foggy/cloudy skies: (1) the degr
