In this study, low quality waste cooking oil with high total acid value, has been used for biodiesel production. The main factors affecting the reaction has been analysed using Response Surface Methodology (RSM). A quadratic model representing the interrelationships between reaction variables and free fatty acids (FFA) conversion has been developed. Analysis of variance (ANOVA) has been used for c

Employing a large number of antennas at the base station, massive MIMO significantly improves spectral efficiency and transmit power efficiency. On the other hand, massive MIMO also introduces unprecedented implementation challenges, especially in terms of processing and storage of large-size channel state information (CSI) matrices. Since on-chip memory is generally very expensive and has limited

This work explores the catalytic activity of decavanadate (V10)-based catalysts in the selective oxidation of ethylbenzene (EB), a model compound of lignin-derived molecules, under mild conditions. The goal is to assess the catalytic efficiency, product selectivity, and the influence of counter-ions on activity through systematic testing of parameters such as temperature and catalyst loading. Addi

This study examines the production of morphosyntax in Swedish-speaking children diagnosed with Developmental Language Disorder (DLD). Data from a Sentence Repetition Task was used to investigate if there is an implicational order according to Processability Theory (PT) in grammatical structures produced by school-age children with DLD. PT is a cognitive theory of language development that assumes

The 14th Waffen-SS Division Galizien was set up in 1943 by Ukrainian volunteers, largely sympathetic to the more conservative Melnyk wing of the Organization of Ukrainian Nationalists (OUN(m)). Its members took a personal oath of allegiance to Adolf Hitler and served in a number of capacities on the eastern front. In addition to combat at the front, the unit partook in the crushing of the Slovak N

Cerebrospinal fluid (CSF) α-synuclein (α-syn) seed amplification assays (SAAs) can detect Lewy body pathology (LBP) with high accuracy but are invasive and costly. To address these challenges, this study evaluated a two-step workflow combining prescreening via smell-function testing with confirmatory CSF α-syn SAA testing only in individuals with reduced smell, for predicting postmortem LBP status

Digital innovation offers promising avenues for accessible, engaging, and user-friendly training solutions, crucial for promoting safety among manufacturing workers. However, optimizing these solutions demands a profound understanding of workers’ needs and preferences in interacting with these digital systems. The ongoing “DigiSafeMan” project aims to develop a prototype of a digital training tool

Objective: To gain deeper understanding of how teenage males view abortion, adolescent fatherhood, sexual behavior, and use of contraception. Method: We conducted six focus-group interviews with 17-year-old boys (n = 40). The interviews were tape-recorded, transcribed verbatim, and analyzed using manifest content analysis. Results: Adolescent fatherhood was considered to be a catastrophe and abort

Brevmall Vice-Chancel lor Regulation regarding first aid training for employees at Lund University According to the “Work environment policy for Lund University including tar- gets and action plans for the period 2003-2005” adopted on 9 January 2003, one of the targets was that “a plan for first aid training shall be produced”. The Divi- sion of Buildings was made responsible for producing a regul

Brevmall Vice-Chancel lor Regulation regarding children’s visits to sites of work or stud- ies The Swedish Work Environment Act (AML) regulates conditions at workplaces and educational premises. In general, it states that ”Work shall be planned and arranged in such a way that it can be carried out in healthy and safe surround- ings” and ”The employer shall take all the precautions necessary to pre

Coarctation of the aorta is a congenital heart anomalyinvolving constriction of an aortic segment, associated with wall thickening of media and the formationof overlapping infolding of neointimal tissue. For thefirst time it was described by Morgagni in 1760. Thispathology represents 5% -7% of all congenital heartdiseases, with an incidence of approximately 3 casesto 10 000 neonates1. The typical

Osteonecrosis (ON) is a common complication of glucocorticoid-based Hodgkin lymphoma (HL) treatment, but the natural evolution and prognosis of ON lesions remain poorly understood. We describe the radiological evolution of ON lesions identified in a Nordic population-based cohort of paediatric HL patients. Magnetic resonance images of suspected ON lesions were centrally reviewed to confirm ON diag

We present a new methodology involving the simultaneous refinement of both x-ray absorption and x-ray diffraction spectra (x-ray absorption/diffraction structural refinement, XADSR) to study the hydration and ion pair structure of CaCl2 and RbBr salts in concentrated aqueous solutions. The XADSR method combines the x-ray absorption fine structure (XAFS) spectral analysis of both the cation and ani

The stereoselective reduction of ketones catalysed by alcohol dehydrogenase from Thermoanaerobium brockii was studied in different reaction media, hexane at controlled water activities, hexane with 2.5% water (biphasic) and pure water. The reactions were studied in the temperature range from -1 to 50°C. Increasing the water activity from 0.53 to 0.97 increased the reaction rate 16-fold. The rate w

Background: Differential diagnosis of rhabdomyosarcoma (RMS) is challenging. Sineoculis homeobox homolog 1 (SIX1) is an oncogene involved in skeletal muscle differentiation. We compared protein expression patterns of SIX1 in RMS and its most common differential diagnoses. Methods: SIX1 immunohistochemistry in 36 RMS and in 33 tumors from seven differential diagnostic subtypes were evaluated. The f

Cesium lead iodide (CsPbI3) perovskite nanocrystals (NCs) suffer from a known transformation at room temperature from their red-emitting (black) to non-emitting (yellow) phase, induced by the tilting of PbI6 octahedra. While the reported attempts to stabilize CsPbI3 NCs mainly involve Pb2+-site doping as well as compositional and/or NC surface engineering, the black phase stability in relation onl
