Synthesis of starch nanoparticles and their applications for bioactive compound encapsulation

In recent years, starch nanoparticles (SNPs) have attracted growing attention due to their unique properties as a sustainable alternative to common nanomaterials since they are natural, renewable and biodegradable. SNPs can be obtained by the breakdown of starch granules through different techniques which include both physical and chemical methods. The final properties of the SNPs are strongly inf

Achieving organizational social sustainability through electronic performance appraisal systems : The moderating influence of transformational leadership

Organizational sustainability is the reality which is considered essential for the success of all kind of organizations. Researchers and academicians struggle to conceptualize this phenomenon while practitioners endeavor to achieve it on the ground. Much has been done in resource-affluent countries of the world, whereas in the least developed countries, social sustainability is now becoming a new

Determinants and consequences of heavy episodic drinking among female sex workers in Ethiopia : A respondent-driven sampling study

Background Female sex workers (FSW), due to their working conditions, have an increased likelihood of heavy episodic drinking (HED), which is associated with risky sexual behavior. Nevertheless the specific contribution of HED to risky sexual behavior among FSWs in Ethiopia is not well documented for prevention activities. Objective The purpose of this study was to explore the determinants and con

Clemizole and La3+ salts ameliorate angiotensin II-induced glomerular hyperpermeability in vivo

Angiotensin II (Ang II) induces marked, dynamic increases in the permeability of the glomerular filtration barrier (GFB) in rats. After binding to its receptor, Ang II elicits Ca2+ influx into cells, mediated by TRPC5 and TRPC6 (transient receptor potential canonical type 5 and 6). Clemizole and La3+ salts have been shown to block TRPC channels in vitro, and we therefore tested their potential eff

Investigating lignin-derived monomers and oligomers in low-molecular-weight fractions separated from depolymerized black liquor retentate by membrane filtration

Base-catalyzed depolymerization of black liquor retentate (BLR) from the kraft pulping process, followed by ultrafiltration, has been suggested as a means of obtaining low-molecular-weight (LMW) compounds. The chemical complexity of BLR, which consists of a mixture of softwood and hardwood lignin that has undergone several kinds of treatment, leads to a complex mixture of LMW compounds, making the

Blue-Green Playscapes : Exploring Children’s Places in Stormwater Spaces in Augustenborg, Malmö

The urbanisation of cities increases the demands on, and complexity of, urban land use. Urban densification is challenging urban green space. Cities have responded to this challenge by adopting a multiple-use strategy where different functions share space. Shrinking open space has to contain solutions for everyday functions such as bicycle parking, waste sorting, blue-green stormwater systems, and

TB and HIV Epidemiology and Collaborative Service : Evidence from Ethiopia, 2011-2015

Background: Integrating and scaling up tuberculosis (TB) and HIV services are essential strategies to achieve the combined goals ending both TB and HIV, especially in TB and HIV high burden countries. This study aimed to examine the prevalence of TB and HIV co-infection and the implementation of collaborative services in Ethiopia.Methods: We used a national sentinel surveillance TB/HIV co-infectio

Hovering flight in hummingbird hawkmoths : Kinematics, wake dynamics and aerodynamic power

Hovering insects are divided into two categories: ‘normal’ hoverers that move the wing symmetrically in a horizontal stroke plane, and those with an inclined stroke plane. Normal hoverers have been suggested to support their weight during both downstroke and upstroke, shedding vortex rings each half-stroke. Insects with an inclined stroke plane should, according to theory, produce flight forces on

Estimating the service life of timber structures concerning risk and influence of fungal decay—A review of existing theory and modelling approaches

Wood is a renewable resource and a promising construction material for the growing bio-based economy. Efficiently utilising wood in the built environment requires a comprehensive understanding of the dynamics regarding its usability. Durability is an essential property to consider, as various types of exposure create conditions for the deterioration of wood through biotic and abiotic agents. Biode

A droplet acoustofluidic platform for time-controlled microbead-based reactions

Droplet microfluidics is a powerful method used to characterize chemical reactions at high throughput. Often detection is performed via in-line optical readout, which puts high demands on the detection system or makes detection of low concentration substrates challenging. Here, we have developed a droplet acoustofluidic chip for time-controlled reactions that can be combined with off-line optical

The Brittle-Ductile Transition in Porous Limestone : Failure Mode, Constitutive Modeling of Inelastic Deformation and Strain Localization

Understanding of the mechanics of the brittle-ductile transition (BDT) in porous limestone is significantly more challenging than for sandstone because of the lack of consistent acoustic emission activity in limestone, meaning that one must rely on alternative techniques. In this paper, we investigate systematically the failure modes in Indiana limestone using X-ray microComputed Tomography imagin

Microvesicles in plasma reflect coronary flow reserve in patients with cardiovascular disease

High levels of microvesicles (MVs), a type of extracellular vesicles, are detected in several pathological conditions. We investigated the connection between coronary flow reserve (CFR), a prognostic clinical parameter that reflects blood flow in the heart, with levels of MVs and their cargo, from plasma of patients with cardiovascular disease. The PROFLOW study consists of 220 patients with prior

Multiple integrated metabolic strategies allow foraminiferan protists to thrive in anoxic marine sediments

Oceanic deoxygenation is increasingly affecting marine ecosystems; many taxa will be severely challenged, yet certain nominally aerobic foraminifera (rhizarian protists) thrive in oxygen-depleted to anoxic, sometimes sulfidic, sediments uninhabitable to most eukaryotes. Gene expression analyses of foraminifera common to severely hypoxic or anoxic sediments identified metabolic strategies used by t

When gold turns to sand : A review of the challenges for fossil fuel rich states posed by climate policy

Petrostates face an unprecedented crisis as oil and gas revenues, on which their economies and states are built upon, are set to diminish rapidly the coming 20 years. The decline in revenues is an effect of the adopted climate policies in the major oil consuming countries that, together with a strong development of renewable energy, reduces the future demand for oil and gas.

Occupational Injuries to Senior Farmers in Sweden

The prevailing demographic change in the western world means that theworkforce is becoming older. Farmers in particular often work beyond the normalretirement age, in a challenging physical environment. For example, the agriculturalsector has the most hazardous work environment in Sweden. Therefore, it is interestingto examine the following questions: Are senior farmers more frequently involvedin

Patch Testing with a New Composition of the Mercapto Mix - A Multicenter Study from the International Contact Dermatitis Research Group

Background Mercaptobenzothiazole compounds are associated with allergic contact dermatitis caused by rubber products. Several screening substances have been used for patch testing. Objective To compare the frequency of positive test reactions to a mercapto mix containing a higher concentration of 2-mercaptobenzothiazole with reactions to the combination of 2-mercaptobenzothiazole 2.0% and mercapto

Åtgärder för att minska risken för arbetsskador bland äldre lantbrukare

På grund av den förändrade demografin blir det allt fler äldre inom arbetskraften i västvälden. Detta inte minst inom lantbruket där antalet äldre som arbetar kvar till en hög ålder är betydande. De generella fysiologiska förändringarna med ökande ålder, som exempelvis sämre syn, hörsel och reaktionsförmåga, är riskfaktorer för att drabbas av arbetsskador. Lantbruket är samtidigt en av Sveriges fa
