Boosting Ethanol Productivity of Zymomonas mobilis 8b in Enzymatic Hydrolysate of Dilute Acid and Ammonia Pretreated Corn Stover Through Medium Optim…
2019
The presence of toxic degradation products in lignocellulosic hydrolysate typically reduced fermentation rates and xylose consumption rate, resulting in a decreased ethanol productivity. In the present study, Zymomonas mobilis 8b was investigated for high cell density fermentation with cell recycling to improve the ethanol productivity in lignocellulosic hydrolysate. The fermentation performances of Z. mobilis 8b at various conditions were first studied in yeast extract-tryptone medium. It was found that nutrient level was essential for glucose and xylose co-fermentation by Z. mobilis 8b and high cell density fermentation with cell recycling worked well in yeast extract-tryptone medium for …
Diet estimation and comparison of fatty acid-based diet modelling methods
2019
Trophic interactions have been a popular research subject among ecologists for decades because understanding the structure of food webs is essential in understanding consumer-resource interactions and complex ecosystems. Consumer diet estimation with biological tracer-based mixing models is an important and recently rapidly developing tool for deciphering aquatic food webs. Bayesian frameworks have been introduced to estimate diets accurately with stable isotope proportions. The low quantity of different stable isotope tracers, however, limits greatly the diet estimation accuracy of complex consumer diets. Therefore, fatty acids have been used as biological tracers to multiply the quantity …
Strange vegetation: Emotional undercurrents of Tove Jansson’s Moominvalley in November
2018
This article investigates the emotional undercurrents of Tove Jansson’s Moominvalley in November. I argue that one of the main characters of Jansson’s book is the autumn forest that surrounds the abandoned Moomin house. The decomposing forest is not just an emblem of the inner lives of the guests that gather in the house but is an active character itself: an ambiguous life form that creeps in the house and must be expelled from its living core. I further demonstrate that the emotion of disgust has a crucial role in Jansson’s narrative, and that an adequate analysis of the intentional content of disgust allows us to see what is at issue in the relations between the characters. In my reading,…
'Foreign Readers and the Imperishable Troll' : travelling to locations with connections to Tove Jansson and her works
2022
The following piece is based on the lectio praecursoria presented at the defense of the doctoral dissertation ‘Ideal Absence and Situated Readers: Experiencing Space Through Connection to Tove Jansson and her Works’ which was publicly discussed on November 3, 2021, at the University of Jyväskylä. The full version of the dissertation can be found at: http://urn.fi/URN:ISBN:978-951-39-8861-6. peerReviewed
NIS-direktiivin kahdet kasvot : riskit ja riskienhallinta
2017
Euroopan unionin verkko- ja tietoturvadirektiivi, eli NIS-direktiivi, annettiin heinäkuussa 2016 ja sitä on sovellettava jäsenvaltioissa viimeistään 10. toukokuuta 2018. Direktiivin tavoitteena on parantaa jäsenmaiden tietoturvaa ja sitä kautta sisämarkkinoiden toimintaedellytyksiä. Se koskettaa suoraan digitaalisia toimijoita ja erikseen määriteltyjä keskeisiä toimijoita, mutta sen vaikutusten voidaan olettaa ulottuvan myös näiden ryhmien ulkopuolelle muun muassa palveluntarjoajiin. Vaikka direktiivi annettiin samoihin aikoihin ja sen soveltaminen aloitetaan myös samoihin aikoihin Euroopan unionin tietosuoja-asetuksen (GDPR) kanssa, on se jäänyt huomattavasti pienemmälle huomiolle kuin tie…

Blackfly Larvae (Simulium spp.) Can Intensify Methylmercury Biomagnification in Boreal Food Webs
2020
AbstractGlobal pollution of mercury (Hg) threatens ecosystem and human health. We measured total Hg (THg) and monomethylmercury (MMHg) concentrations in filter-feeding blackfly (Simulium spp.) larvae in the inflows and the outflows of six boreal lakes with no Hg point source pollution. THg in the larvae ranged from 0.03 to 0.31 mg kg−1 dw and MMHg between 0.02 and 0.25 mg kg−1 dw. The proportion of MMHg in the larvae was 74 ± 0.16% and ranged from 43 to 98% of THg, the highest proportions being comparable to those typically found in aquatic predatory insects and fish. We compared the larvae MMHg concentrations to river water quality, catchment land-use, and to size-adjusted lake pike THg da…
SDN controllers security issues
2017
Software-Defined Networking (SDN) is essentially varying the way we design and manage networks, which makes a communication network programmable. In SDN, a logically centralized controller has straight control over the packet-handling functions of the network switches, using a standard, open API (Application Programming Interface) such as OpenFlow. OpenFlow is a broadly used protocol for software-defined networks (SDNs) that presents a new model in which the control plane is inattentive from the forwarding plane for the network devices. In SDN approach centralized entities called "controllers" perform like network operating systems run dissimilar applications that accomplish and control the…
