Bioinspired citrate-carbonate-apatite (cAp) nanocrystals doped with divalent transition metal (M) ions, i.e., Mn2+, Co2+, and Ni2+, were prepared by batch thermal decomplexing of Ca2+/M/citrate/phosphate/carbonate solutions at 80 and 37 degrees C, with initial Ca2+/M molar ratios of 9:1 and 5:5, and at different crystallization times ranging from 1 to 96 h. A thorough chemical, crystallographic, a
With its unprecedented light-collecting area for night-sky observations, the Cherenkov Telescope Array (CTA) holds great potential for also optical stellar astronomy, in particular as a multi-element intensity interferometer for realizing imaging with sub-milliarcsecond angular resolution. Such an order-of-magnitude increase of the spatial resolution achieved in optical astronomy will reveal the s
The aim of the this study was to investigate the ozone dosage required to remove active pharmaceutical ingredients (APIs) from biologically treated wastewater of varying quality, originated from different raw wastewater and wastewater treatment processes. Secondary effluents from six Swedish wastewater treatment plants (WWTP) were spiked with 42 APIs (nominal concentration 1 mu g/L) and treated wi
This paper presents a 1MHz bandwidth, ΔƩ fractional-N PLL as the frequency synthesizer for LTE. A noise cancellation path composed of a novel hybrid ΔƩ DAC with 9 output bits is incorporated into the PLL in order to cancel the out-of-band phase noise caused by the quantization error. Further, a re-timing circuit is proposed to reduce the nonlinearity in the Charge Pump and provide pulse shaping si
The acoustic emission that is detectable in the forming of complex thin part plates contains information about the quality of the pressed plates. The information can be used as process control and to filter out advanced thin plates with defects such as cracks. The article describes the results obtained in a try-out pressing process in special developed punch-die pairs with different pressing
This thesis focuses on collaboration in interorganizational implementation processes carried out in temporary organizations. Due to the increased level of collaboration in logistics, interorganizational implementation projects are becoming increasingly important. Consequently, for companies to stay competitive from a logistical point of view, interorganizational relationships need to be addressed.
The kinetics and mechanism for the overall reaction (i) (X = Cl or Br) have been studied at 25.0 °C using stopped-flow spectrophotometry. 3[AuX4]–+ 7SCN–+ 4H2O → 3[Au(SCN)2]–+ HSO4–+ HCN + 12X–+ 6H+ (i), The reaction takes place in two kinetically well separated steps. The initial, rapid process can be identified as stepwise ligand substitutions (ii) (n= 0–3) which take place via direct ligand diThe kinetics and mechanism for the overall reaction (i) (X = Cl or Br) have been studied at 25.0 °C using stopped-flow spectrophotometry. 3[AuX4]–+ 7SCN–+ 4H2O → 3[Au(SCN)2]–+ HSO4–+ HCN + 12X–+ 6H+ (i) The reaction takes place in two kinetically well separated steps.

This tutorial presents an introduction to power scaling concepts for high-order harmonic generation (HHG) and attosecond pulse production. We present an overview of state-of-the-art HHG-based extreme ultraviolet (XUV) sources, followed by a brief introduction to basic principles underlying HHG and a detailed discussion of macroscopic effects and scaling principles. Particular emphasis is put on a
Little is presently known about the unique nanostructure of deep eutectic solvents (DES). The order of the liquid-solid phase transition is contended and whether DES-water mixtures are merely aqueous solutions, or have properties dominated by the eutectic pair, is unclear. Here, we unambiguously show the structure of choline chloride-malic acid (malicine) as a liquid, and also in solid and hydrate
This paper focuses on the performance and efficiency of an HCCI (Homogenous Charge Compression Ignition) engine system running on natural gas or landfill gas for stationary applications. Zero-dimensional modelling and simulation of the engine, turbo, inlet and exhaust manifolds and inlet air conditioner (intercooler/heater) are used to study the effect of compression ratio and exhaust turbine size
Popular Abstract in Swedish Potatis har varit, och är fortfarande ett viktigt baslivsmedel i svensk kosthållning. Det finns många sorter med olika egenskaper vilket bidrar till dess variationsrikedom. Potatisen är en rik källa till stärkelse, kostfibrer samt vitaminer och mineraler, t ex C-vitamin och järn. En invändning mot potatis ur nutritionell synvinkel är att stärkelsen lätt bryts ned av enzDespite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. This results in unfavourably high glycaemic and insulinaemic responses (glycaemic index, GI and insulinaemic index, II, respectively). Su
In this paper we address the test scheduling problem for system-on-chip. Different from previous approaches where it is assumed that all tests will be performed until completion, we consider the cases where the test process will be terminated as soon as a defect is detected. This is common practice in production test of chips. The proposed technique takes into account the probability of defect-det
We used long-term monitoring data to assess causes behind a recent shift front a clear to a turbid water state in Lake Takern, Sweden. The lake has a previous record of shifts between clear-water and turbid states. but the causes behind these shifts are not well known. During the recent shift, which occurred in 1995-1997, Submerged vegetation Subsequently declined after a 30-year period of clear-w
This article focuses on the ways in which women employed in Vietnam’s heavy industry, mitigate and cope with crises at the workplace and in social life. Drawing on ethnographic fieldwork, which I have conducted in the Industrial Zones of northern Vietnam in the international corporations called Xylan and Yate, I examine how women who are working on the floor manage crises entanglements as an unde
The prospects of domestic punishment might compel leaders responsible for the initiation of the war to continue fighting until they achieve favorable war outcomes (Croco 2011, 2015). As applied to war duration, this logic implies that ‘culpable’ leaders do not have incentives to end a war that will bring defeat. This paper argues that leaders can escape this dilemma by blaming and replacing their
Context: Alkyl glucosides and alkyl poly-glucosides are widely used as wetting agents, surfactants and emulsifiers in several industrial and cosmetic products. They are known as well-tolerated and are usually added to the primary surfactants in order to reduce the irritating potential of the main foaming agents.Objective: Recently, some authors suggested that allergic contact dermatitis to alkyl g
Many modern drugs contain chiral amine moieties and the need for more efficient processes to synthesize these amines in high optical purity and concentration are greatly demanded by the fine chemical and pharma industry. Amine transaminases (ATA) allow for the direct asymmetric synthesis of optically pure amines from ketone substrates. Although academia and industry have been researching ATAs exte
The turnover of albumin is increased in both peritoneal dialysis (PD) and hemodialysis (HD) due to increased external losses, normally leading to compensatory increases in the hepatic albumin synthesis. The normal rate of albumin synthesis is on the order of 12 g/day corresponding to an equally large albumin fractional catabolic rate of ~4% daily. Most albumin catabolism is assumed to occur in the
