In this study, we compared the GR51PP (hydrophobic/polysulfone) membrane with a series of hydrophilic (regenerated cellulose) membranes with the aim of increasing the retention of products and decreasing membrane fouling. The raw material used was a sodium-based spent sulfite liquor from the sulfite pulping process of spruce and pine. The results show that the hydrophilic membranes were superior t

The Learning with Errors problem (LWE) is one of the main candidates for post-quantum cryptography. At Asiacrypt 2017, coded-BKW with sieving, an algorithm combining the Blum-Kalai-Wasserman algorithm (BKW) with lattice sieving techniques, was proposed. In this paper, we improve that algorithm by using different reduction factors in different steps of the sieving part of the algorithm. In the Rege

Removing obstacles to e-commerce in the Single Market and ensuring effectivetaxation in the context of the digital economy has been high on the political agendaboth in the European Union and beyond. Recently the VAT rules on cross-border ecommerce have gone through a thorough modernisation with a package of newprovisions in the EU VAT legislation coming into effect as of 2019 and 2021.

Body temperature control is essential for survival. In mammals, thermoregulation is mediated by the preoptic area of anterior hypothalamus (POA), with ∼30% of its neurons sensitive to brain temperature change. It is still unknown whether and how these temperature-sensitive neurons are involved in thermoregulation, because for eight decades they have only been identified via electrophysiological re

An improved solution of the non-linear and ill-posed inverse problem of electro-cardiography is presented. The hearts activity is modeled by three di®erent equivalent cardiac sources: 1 moving dipole, 2 and 5 fixed location rotating dipoles. For this purpose a three dimensional volume conductor model of the human body is constructed based on a classical anatomic atlas. This is excited by each one

The introduction of high efficiency and multifunctional equipment for road survey increase not only the quality but also the possibility of integration of different source of data to increase the value of the information. The present research work, starting from a common data source, the Automatic Road Analyzer (ARAN) of the University of Catania, shown as data surveyed with ARAN can be used to de

Background. Rheumatoid arthritis (RA) is characterized by an uncontrolled spread of destructive joint inflammation resembling malignancy. Epidemiological studies have established strong correlation between inflammation and predisposition for cancer. Here we assess the predictive role of the circulating proto-oncogene survivin for clinical and radiological outcome of early RA. Patients and methods.

When addressing infants, adults use a speech register known as infant-directed speech (IDS). Compared to adult-directed speech (ADS), IDS has a number of distinctive acoustic and linguistic features. Vowel hyperarticulation, the expansion of the acoustic space between the corner vowels /i,u,a/, is one feature specifically proposed to facilitate language acquisition processes. Interestingly, the pr

Soot particles undergo considerable changes in composition, morphology, as well as in internal structure during formation from the incipient particles to more mature aggregates, and still there is a lack of understanding of these mechanisms. In this study, soot produced by a mini-CAST soot generator was probed using Raman spectroscopy with focus on soot with large variation in size and fraction of

The optical band gap has been used considerably in evaluating carbon network structures in terms of sp 2 /sp 3 sites and size of aromatic clusters. However, optical band gap determination of soot particles from optical measurements is complex due to the effects of other species including organic compounds, and the contribution of absorption from organics to the total soot absorption in the UV/visi

Objectives. Despite accumulating research on yoga and its positive impact on both physiological and psychological health, it is still unclear how yoga improves health. Two central components of yoga: yogic breathing and mindfulness, may be important mechanisms by which individuals learn to cope with their daily stressors, and thereby reduce their risk of developing stress-related illness.

In this paper we address the problem of resource allocation for alarm traffic in industrial Internet of Things networks using massive MIMO. We formulate the general problem of how to allocate pilot signals to alarm traffic such that delivery is guaranteed, while also minimising the number of pilots reserved for alarms, thus maximising the channel resources available for other traffic, such as indu

In this paper we present new optimization formulations for maximizing the network lifetime in wireless mesh networks performing data aggregation and dissemination for machine-to- machine communication in the Internet of Things. We focus on heterogeneous networks in which multiple applications co-exist and nodes may take on different roles for different applications.

Debate article on how to view the Kalmar Union as a state, and on how to view political-territorial entities in late medieval Europe in general.

In this study, the impact of two different “methods” for teaching ethics as part of the religious education in the Swedish upper secondary school have been compared by means of a non-randomized controlled trial in two parts, involving 15 teachers and 524 students. The question was which “method” had the greatest capacity to generate long-term ethical awareness in the students. The intervention con

Diabetes mellitus is common in Western countries. Secondary complications in various organs occur after type 1 as well as type 2 diabetes. Complications, such as nephropathy, retinopathy and neuropathy, are well known. Specific efforts to treat complications in the lower leg - »the diabetic foot» - have been emphasized. Various complications to diabetes occur also in the upper extremity and hand -
