Improving inorganic composition and ash fusion behavior of spruce bark by leaching with water, acetic acid, and steam pre-treatment condensate

The present study evaluates the effect of water and acetic acid washing on the chemical composition of spruce bark in-depth. Also, washing with steam explosion condensate (SEC) was investigated which is a novel attempt. The leaching kinetics of troubling elements (TE) was studied to understand the leaching behavior of TEs and for upscaling the process. Furthermore, to study the ash transformation

Toward Process-Resilient Lignin-Derived Activated Carbons for Hydrogen Storage Applications

Activated carbons are promising sorbents that have been heavily investigated for the physisorptive storage of hydrogen. The industrial process for production of activated carbons is finely tuned and requires a reliable and uniform feedstock. While the natural biopolymer lignin, a byproduct of several industries, has received increasing interest as a potentially sustainable and inexpensive activate

Cationic surfactants as a non-covalent linker for oxidised cellulose nanofibrils and starch-based hydrogels

Rheological properties of hydrogels composed of TEMPO-oxidised cellulose nanofibrils (OCNF)-starch in the presence of cationic surfactants were investigated. The cationic surfactants dodecyltrimethylammonium bromide (DTAB) and cetyltrimethylammonium bromide (CTAB) were used to trigger gelation of OCNF at around 5 mM surfactant. As OCNF and DTAB/CTAB are oppositely charged, an electrostatic attract

Påverkar intag av natriumbikarbonat eller alkalisk kost aerob respektive anaerob prestationsförmåga för friska individer? – en systematisk litteraturstudie

Bakgrund: För att skelettmuskulaturen ska kunna kontraheras krävs energirika fosfatbindningar som heter adenosintrifosfat (ATP). För att tillgodose muskulaturens behov av energi finns 3 olika system, där det största, som producerar majoriteten av all ATP under vila och längre ansträngningar (>1 minut) är det aeroba systemet. I avsaknad av syre eller när de aeroba processerna inte hinner ta vara p

TOI-1670 b and c : An Inner Sub-Neptune with an Outer Warm Jupiter Unlikely to Have Originated from High-eccentricity Migration

We report the discovery of two transiting planets around the bright (V = 9.9 mag) main-sequence F7 star TOI-1670 by the Transiting Exoplanet Survey Satellite. TOI-1670 b is a sub-Neptune ( Rb=2.06-0.15+0.19 R) on a 10.9 day orbit, and TOI-1670 c is a warm Jupiter ( Rc=0.987-0.025+0.025 R Jup) on a 40.7 day orbit. Using radial velocity observations gathered with the Tull Coudé Spectrograph on the H

Sociala kretsars påverkan på matsvinnsbeteende

How we manage resources, in this case food, based on our culture is the core interest of human ecology. According to systems analysist Donella Meadows, cultural factors, i.e. our mindset, are the most difficult intervention points to access for system change - but also the most effective. This essay examines through a survey and a smaller experiment how prescribed norms and attitudes of social cir

Processes associated with ionic current rectification at a 2D-titanate nanosheet deposit on a microhole poly(ethylene terephthalate) substrate

Films of titanate nanosheets (approx. 1.8-nm layer thickness and 200-nm size) having a lamellar structure can form electrolyte-filled semi-permeable channels containing tetrabutylammonium cations. By evaporation of a colloidal solution, persistent deposits are readily formed with approx. 10-μm thickness on a 6-μm-thick poly(ethylene-terephthalate) (PET) substrate with a 20-μm diameter microhole.

Occupational therapy interventions for adolescents and young adults with depression and anxiety disorders

Bakgrund: Psykisk ohälsa bland ungdomar och unga vuxna har ökat och kommer sannolikt att fortsätta öka på sikt. Depression och ångestsyndrom är bland de vanligaste orsakerna till psykisk ohälsa världen över. Arbetsterapeuter besitter en avgörande kompetens inom aktivitet och hälsa. Denna kompetens kan vara behjälplig för ungdomar och unga vuxna med depression och ångestsyndrom. Syfte: Att kartläggBackground: Mental illness among youth and young adults has increased and will likely continue to increase in the long term. Depression and anxiety disorders are among the most common causes of mental illness worldwide. Occupational therapists possess competence in activity and health. This competence can be helpful for adolescents and young adults with depression and anxiety disorders. Aim: To ov

Targeting of bone morphogenetic protein complexes to heparin/heparan sulfate glycosaminoglycans in bioactive conformation

Bone morphogenetic proteins (BMP) are powerful regulators of cellular processes such as proliferation, differentiation, and apoptosis. However, the specific molecular requirements controlling the bioavailability of BMPs in the extracellular matrix (ECM) are not yet fully understood. Our previous work showed that BMPs are targeted to the ECM as growth factor-prodomain (GF-PD) complexes (CPLXs) via

Formation of ordered mesoporous thin films through templating

Pores in the size range 2.0-20 nm are considered mesopores. Using the sol-gel process and a catalog of surfactant molecules, thin films with ordered mesopores can be produced. Films formed by evaporation-induced self-assembly, growth from solution, and other methods such as vapor phase deposition and pulsed laser deposition are examined. The various patterns derived from these approaches are discu

Obekväma arbetstider och dess påverkan på industriarbetares välmående

Syftet med denna uppsats är att undersöka hur medarbetare upplever att deras obekväma arbetstider påverkar deras välmående i utifrån tre invarianta teman; återhämtning, work-life balance samt lärande. Uppsatsen präglas av ett medarbetarperspektiv på ett stort industriföretag där fyra medarbetare har intervjuats. Två medarbetare arbetar konstant natt och två stycken arbetar tvåskift, det vill säga

The role of phoenixin in the proliferation and migration of ectopic epithelial cells in vitro

AimEndometriosis is one of the most common gynecologic diseases in women of reproductive age. The pathophysiology of endometriosis is still not fully understood. Phoenixin (PNX-14) is a newly discovered neuropeptide that regulates the hypothalamo–pituitary–gonadal (HPG) axis and reproductive functions. Recently, we reported that PNX-14, its precursor protein and receptor were expressed in human en

Water-Mills in Northwest Semitic, Rabbinica and Archaeology : Levantine and Babylonian Evidence

This article aims at assembling the available facts concerning the exploitation of water-power in ancient and Early Mediaeval Palestine (and partly Jewish Babylonia)—those to be found in written (that is, Rabbinic) sources as well as those deriving from archaeological finds. Both groups of materials are scant, and the conclusions remain tentative. But it can be stated almost with certainty that wa

Migration direction in a songbird explained by two loci

Migratory routes and remote wintering quarters in birds are often species and even population specific. It has been known for decades that songbirds mainly migrate solitarily, and that the migration direction is genetically controlled. Yet, the underlying genetic mechanisms remain unknown. To investigate the genetic basis of migration direction, we track genotyped willow warblers Phylloscopus troc

Icke-angreppsklausuler i patentlicenser - Intresseavvägningen mellan patent- och konkurrensrätt

Patentlicensavtal utgör ett effektivt verktyg för exploatering av patentskyddad innovation. Avtalen anses därför i allmänhet vara konkurrensfrämjande. Emellertid kan patentlicenser innehålla avtalsklausuler som kan vara problematiska ur ett konkurrensperspektiv. Icke-angreppsklausuler, som hindrar licenstagaren från att utmana den immateriella giltigheten i det licensierade patentet, utgör en sådaPatent licensing is considered an effective tool for the exploitation of technology protected by the IPR. Thus, in general, licensing is pro-competitive. However, there are cases when licensing agreements contain clauses that can be problematic in relation to EU competition law. The no-challenge clause, which obligates the licensee not to contest the validity of the intellectual property of the li
