The results of a round robin test on isothermal (heat conduction) calorimetry are presented. A total of 18 participants using three types of instruments conducted 3-day measurements of the hydration of one rapidly hardening Portland cement and one slag-containing cement. The results confirm that isothermal calorimetry is a suitable method for the determination of heat of hydration. As a part of th
The release of dissolved silicon (DSi) from A and B horizons was investigated with leaching tests on unsaturated columns. As forest A horizons have larger biogenic Si (BSi) pools than arable lands, we compared the Si release from a forest and a cropland from the same geographical region developed on a Luvisol in Belgium and a Cambisol in Sweden. The A horizons released a quickly dissolving Si frac
A numerical model was developed of beach morphological evolution in the vicinity of coastal structures. The model includes five sub-models for random wave transformation, surface roller development, nearshore wave-induced currents, sediment transport, and morphological evolution. The model was validated using high-quality data sets obtained during experiments with a T-head groin and a detached bre
The use of commercial proteases, bromelain and Protex 30L for oil extraction/recovery of polyunsaturated fatty acids (PUFA) from Nile perch and salmon heads was evaluated. Four phases were obtained after hydrolysis, oily phase, emulsion, aqueous phase and sludge. An increase in water content during the hydrolysis resulted in a decrease in oil yield. Maximum oil yield was obtained when hydrolysis w
In this paper, we report experimentally and theoretically a surface photocatalysis reaction of 4-aminothiophenol (PATP) to p,p'-dimercaptoazobenzene (DMAB) on Au, Ag, and Cu colloids. Surface enhanced Raman scattering (SEAS) spectra of PATP on Au and Cu colloids are significantly different from the normal Raman spectrum of PATP powder. Quantum chemical calculations reveal that PATP on Au and Cu co
On the basis of a T = 1 icosahedral capsid model, the capsomer-polyion co-assembly process has been investigated by molecular dynamics simulations using capsomers with different net charge and charge distribution as well as linear, branched, and hyper-branched polyions. The assembly process was characterized in terms of the time-dependent cluster size probabilities, averaged cluster size, encapsul
The effect of applied potential pulses on DNA functionalization (thiolated single stranded DNA) and hybridization processes has been monitored in-situ on gold surfaces using electrochemical quartz crystal microbalance with dissipation (EQCM-D). The applied potentials were chosen with respect to the potential of zero charge (E-pzc) of the gold surfaces: a positive potential to attract the negativel
A bi-enzymatic cascade consisting of a Baeyer-Villiger monooxygenase and an alcohol dehydrogenase (ADH) was designed in a convergent fashion to utilise two molar equivalents of cyclohexanone (CHO) and one equivalent of 1,6-hexanediol as a 'double-smart cosubstrate' to produce epsilon-caprolactone (ECL) with water as sole by-product. The convergent enzymatic cascade reaction reported herein, is per
Palaeomagnetic and geochronological studies on mafic rocks in the Lake Ladoga region in South Russian Karelia provide a new, reliably dated Mesoproterozoic key paleopole for the East European Craton (Baltica). U-Pb dating on baddeleyite gives a crystallisation age of 1452 +/- 12 Ma for one of the studied dolerite dykes. A mean palaeomagnetic pole for the Mesoproterozoic dolerite dykes. Valaam sill
It is generally maintained that learning should be a part of the daily routines of many organizations; this is often referred to as lesson learned processes. The purpose of organizational learning is to foster improvements that seek to both reduce incidents and accidents and reduce their consequences when they nevertheless happen. Safety work is widespread among many organizations, e.g. aviation,
In many organizations it is considered of vital importance to translate its vision and strategy into objectives, to determine the best means of achieving these and to review the results – with participation from all members, from management to shop floor. The objective of this study was to make a first test of a method that could be applied for verbalizing and communicating a common vision and ide
Popular Abstract in Swedish Ateroskleros, ofta kallad åderförkalkning, är en sjukdom som påverkar stora och medelstora artärer såsom aorta, kranskärl, karotis och perifera artärer. Åderförkalkning i kranskärlen orsakar 70 % av dödsfallen hos dessa patienter och räknas som den främsta dödsorsaken i västvärlden. Cerebrovaskulär sjukdom orsakar 20 % av dödsfallen och är den tredje vanligaste dödsorsaAtherosclerosis is the leading cause of death and disability in the western world. Its clinical complications include acute myocardial infarction, sudden death and stroke. Thirty to 40 % of all ischemic strokes are caused by a carotid stenosis. The acute clinical event is triggered by an occluding thrombosis and even more frequently by embolization. Besides the degree of stenosis, the structure of
In tunnels or long corridors, the combustion products of the fire are confined to spread in one or two directions, forming a ceiling-jet flow. For safety assessment and emergency treatment, it is important to investigate and understand the behavior of the ceiling-jet flow. In this paper, a simple model has been presented, in terms of Richardson number and non-dimensional ceiling-jet thickness, to
A Baeyer-Villiger monooxygenase has been identified in the genome sequence of Dietzia sp. D5. Sequence similarity search revealed that the enzyme belongs to a group of BVMOs that are closely related to ethionamide monooxygenase from Mycobacterium tuberculosis (EthA). The BVMO was expressed in E. coli BL21-CodonPlus(DE3)-RP and the best expression was achieved when the E. coli cells were cultivated
In gastronomic tourism, Slow Food has gained considerable attention. Cittáslow, a network of towns, are working with qualitative local urban development, based on similar principles as Slow Food. This article studies how destination development and destination marketing is conducted in a cittáslow context. A study was conducted in three cittáslow towns in Northern Italy. All three towns worked amb
The genes encoding human manganese superoxide dismutase (MnSOD) and Vitreoscilla hemoglobin (VHb) were fused inframe to generate a bifunctional enzyme that possessed MnSOD and peroxidase-like activities. At neutral pH, the coupling of the SOD and peroxidase reactions revealed that the bifunctional enzyme exhibited a 2.5 times shorter transient period and a 1.67 times higher reaction rate at steady
Electrocardiograms are routinely obtained in clinical follow-up of patients with asymptomatic aortic stenosis (AS). The association with aortic valve, left ventricular (LV) response to long-term pressure load, and clinical covariates is unclear and the clinical value is thus uncertain. Data from clinical examination, electrocardiogram, and echocardiogram in 1,563 patients in the Simvastatin and Ez
PURPOSE. Alzheimer disease (AD) and age-related ocular diseases are characterized by inflammation and accumulation of insoluble proteins. We aimed to investigate the detectability and clinical relevance of a panel of AD-related markers, such as Alzheimer peptides and chemokines, in the aqueous humor (AH) samples taken from patients with cataract only, or cataract and 1 other ocular disease.
