Engraved in the Body : Ways of Reading Finnish People's Memories of Mental Hospitals
2021
Finnish psychiatric practice has been heavily based on institutionalization. Mental hospitalsMental hospital have thus been part of Finns' lives in many ways. Our multidisciplinary researchMultidisciplinary research group has investigated how experiences in these institutions are remembered today by analysing writings by patients, relatives, personnel and their children, collected in 2014--2015 with the Finnish Literature Society. The memoriesMemory cover phases of psychiatric care from the 1930s to the mid-2010s. This article presents multiple ways in which experiences that are often difficult verbalize can be interpreted, e.g. by drawing on perspectives from creative, artistic and cultura…
A generalized noise study of solid-state nanopores at low frequencies
2017
Nanopore technology has been extensively investigated for analysis of biomolecules, and a success story in this field concerns DNA sequencing using a nanopore chip featuring an array of hundreds of biological nanopores (BioNs). Solid-state nanopores (SSNs) have been explored to attain longer lifetime and higher integration density than what BioNs can offer, but SSNs are generally considered to generate higher noise whose origin remains to be confirmed. Here, we systematically study low-frequency (including thermal and flicker) noise characteristics of SSNs measuring 7 to 200 nm in diameter drilled through a 20-nm-thick SiNx membrane by focused ion milling. Both bulk and surface ionic curren…
Kieli(koulutus) ja nationalismi Singaporessa : ratkaisemattomia jännitteitä standardienglannin, äidinkielten ja singlishin välillä
2018
Edellyttääkö kansallistunteen syntyminen koko väestön kesken jaettua ja omaksi koettua kieltä? Singapore tarjoaa mielenkiintoisen esimerkin tapauksesta, jossa vastaus kysymykseen ei ole lainkaan yksiselitteinen. Nationalismin näkökulmasta Singaporen tilanteen tekee erityisen mielenkiintoiseksi se, että valtiojohto pyrkii rakentamaan kansakuntaa ilman kielipolitiikkaa, jossa olisi keskiössä, tai edes läsnä, koko väestölle yhteistä autenttisena pidettyä kieltä. Tämä artikkeli pohjaa pro gradu -tutkielmaani (Slioor 2018) varten tekemääni tutkimustyöhön. Se ei kuitenkaan ole tiivistelmä tutkielman löydöksistä, ja näkökulman valinta on hieman erilainen. Tarkoituksena on esitellä Singaporen tilan…

The life cicle of Plasmopara viticola
2000
Plasmopara viticola (Berk. & M. A. Curtis) Bed. & De Toni is an obligate biotrophic oomycetous organism which causes downy mildew of grape vine. An understanding of its life-cycle is essential in relation to the pathology and epidemiology, and for the development of better control of the disease. It overwinters as oospores within fallen leaves.
Net currents obtained from zero-average potentials in single amphoteric nanopores
2013
We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.
The Role of Parliament in Sustainable Development Goals: A Case Study of Southeast Asia in International Parliamentary Forums
2021
Parliament has its role in supporting Sustainable Development Goals (SDG). SDG number 16 on peace, justice, and strong institution states one indicator of a legislative institution (for “responsive, inclusive, participatory and representative”, that the Inter-Parliamentary Union (IPU) commits to achieve. However, parliament must support the government in achieving all SDG programs as stated in Agenda 2030. What is the role of parliament in this and how to achieve it? This paper aims to show that the role of parliament in SDG is beyond the traditional legislative role of legislating, budgeting and overseeing the government, but more on representing people, meaning channeling people’s voice a…
Melt Processed PCL/PEG Scaffold with Discrete Pore Size Gradient for Selective Cellular Infiltration
2016
In order to develop scaffold able to mimic the natural gradient properties of tissues, biphasic and triphasic approaches were adopted. In this work, polycaprolactone/polyethylene glycol (PCL/PEG) scaffolds were prepared by using a combination of melt mixing and selective leaching without harmful solvents. The method permitted to develop three-layer scaffolds with high control of porosity and pore size. The mechanical properties were evaluated under physiological condition in order to simulate the real conditions of work. Co-culture of osteoblastic and fibroblastic mice cells were carried out in order to study the differential cellular permeation through the different pore size layers.
Rotator cuff calcific tendinopathy: from diagnosis to treatment
2018
Rotator cuff calcific tendinopathy (RCCT) is a very common condition caused by the presence of calcific deposits in the rotator cuff (RC) or in the subacromial-subdeltoid (SASD) bursa when calcification spreads around the tendons. The pathogenetic mechanism of RCCT is still unclear. It seems to be related to cell-mediated disease in which metaplastic transformation of tenocytes into chondrocytes induces calcification inside the tendon of the RC. RCCT is a frequent finding in the RC that may cause significant shoulder pain and disability. It can be easily diagnosed with imaging studies as conventional radiography (CR) or ultrasound (US). Conservative management of RCCT usually involves rest,…
