Nitrate removal microbiology in woodchip bioreactors : a case-study with full-scale bioreactors treating aquaculture effluents

2020

Woodchip bioreactors are viable low-cost nitrate (NO3−) removal applications for treating agricultural and aquaculture discharges. The active microbial biofilms growing on woodchips are conducting nitrogen (N) removal, reducing NO3− while oxidizing the carbon (C) from woodchips. However, bioreactor age, and changes in the operating conditions or in the microbial community might affect the NO3− removal as well as potentially promote nitrous oxide (N2O) production through either incomplete denitrification or dissimilatory NO3− reduction to ammonium (DNRA). Here, we combined stable isotope approach, amplicon sequencing, and captured metagenomics for studying the potential NO3− removal rates, a…

Removal of hexavalent chromium from wastewaters by bone charcoal

1999

The adsorption of hexavalent chromium onto bone charcoal was studied as a function of time, amount of charcoal, pH, concentration of chromium and sample volume. The cross interference with other elements was also investigated. Tests were carried out with solutions of chromium(VI) at concentrations between 5 and 25 mg · L–1. Chromium removal efficiencies higher than 90% were achieved at pH = 1 using 2 g of bone charcoal and a stirring time in the order of 30 min. Acid and alkaline pretreatments of bone charcoal did not improve the sorption capacity of bone charcoal against Cr(VI). The presence of other ions had practically no influence on the chromium removal. The presence of a matrix of tan…

Magnetofection of acoustically active „magnetic microspheres“ (Magnetobubbles) — Induction of angiogenesis via non-viral transfection of VEGF

2009

Adenoviral transduction of the VEGF gene in an oversized skin flap increases flap survival and perfusion. In this study we investigated the potential of magnetofection of magnetic lipospheres containing VEGF165-cDNA on survival and perfusion of ischemic skin flaps and evaluated the method with respect to the significance of applied magnetic field and ultrasound.

Kasvatus filosofiaan : tutkielma Matthew Lipmanin pedagogisesta ajattelusta

2012

Tutkielma käsittelee lapsille suunnatun filosofian pioneerin Matthew Lipmanin pedagogista ajattelua. Tavoitteena on etsiä vastausta siihen, miksi Lipmanin mukaan filosofiaa tulisi opettaa lapsille kouluissa jo varhaisesta ikävaiheesta lähtien. Lisäksi tarkastelen lasten filosofointia kohtaan suunnattua kritiikkiä sekä Lipmanin ajatteluun mahdollisesti liittyviä teoreettisia ongelmia. Lähestymistapa on ongelmakeskeinen. Tutkielman alussa tarkastellaan koulutuksen standardiparadigmaa, jota Lipman pitää ongelmallisena. Kyseisessä paradigmassa kasvatus ymmärretään passiivisena tiedon siirtämisenä tietäviltä tietämättömille. Mallin tilalle Lipman ehdottaa itsenäiseen ajatteluun ja tiedon aktiivi…

Delayed, diffuse acute peritonitis secondary to misplacement of a cystogastrostomic "pigtail" drain in an outpatient after discharge.

2017

Background and aim of the work: Pancreatic pseudocyst endoscopic drainage by pancreatogastrostomy “pigtail” drain placement is spreading worldwide, with high success-rate and low morbidity, and is increasingly performed as outpatient procedure. The paper reports an unusual very early complication of this procedure and discusses the peculiar aspects of this event in an outpatient setting. Methods: The first case of a 56-year-old outpatient developing a postoperative diffused acute peritonitis by gastric juice spilling caused by the misplacement of the distal end of two transgastric drains not reaching the pseudocyst is reported. As the case was programmed as outpatient and acute peritonitis …

Pain neuroscience education and physical exercise for patients with chronic spinal pain in primary healthcare: a randomised trial protocol.

2019

AbstractBackgroundChronic musculoskeletal pain affects more than 20% of the population, and the prevalence is increasing, causing suffering, loss of quality of life, disability, and an enormous expenditure on healthcare resources. The most common location for chronic pain is the spine. Many of the treatments used are mainly passive (pharmacological and invasive) and poor outcomes. The treatments currently applied in the public health system do not comply with the recommendations of the main clinical practice guidelines, which suggest the use of educational measures and physical exercise as the first-line treatment. A protocol based on active coping strategies is described, which will be eva…

Noninvasive Ventilation in Critically Ill Patients

2015

Since its first application in the late 1980s, noninvasive ventilation (NIV) has been the first-line intervention for certain forms of acute respiratory failure. NIV may be delivered through the patient's mouth, nose, or both using noninvasive intermittent positive pressure ventilation or continuous positive airway pressure. When applied appropriately, NIV may reduce morbidity and mortality and may avert iatrogenic complications and infections associated with invasive mechanical ventilation. This article provides physicians and respiratory therapists with a comprehensive, practical guideline for using NIV in critical care. © 2015 Elsevier Inc.

Audiovisual processing of Chinese characters elicits suppression and congruency effects in MEG

2019

Learning to associate written letters/characters with speech sounds is crucial for reading acquisition. Most previous studies have focused on audiovisual integration in alphabetic languages. Less is known about logographic languages such as Chinese characters, which map onto mostly syllable-based morphemes in the spoken language. Here we investigated how long-term exposure to native language affects the underlying neural mechanisms of audiovisual integration in a logographic language using magnetoencephalography (MEG). MEG sensor and source data from 12 adult native Chinese speakers and a control group of 13 adult Finnish speakers were analyzed for audiovisual suppression (bimodal responses…
