New Glass Capillary Gas-Chromatographic Methods for Metabolites in Urine and Serum

1981

The analytical system suggested in this paper is a further development of pre-chromatographic methods and of column switching techniques described in previous papers1,2,3.In order to use modern gas-chromatographic techniques for the determination of metabolites in urine and serum quick and reliable pre-chromatographic methods for extraction, concentration and derivatization must be developed which give final (dosage) volumes of 5 to 10 μl with starting sample volumes of 0.1 ml of urine or 5 ml of serum as described by Dunges4.

Bidirectional Chemo-Switching of Spin State in a Microporous Framework

2009

The ins and outs of spin: Using the microporous coordination polymer {Fe(pz)[Pt(CN)(4)]} (1, pz=pyrazine), incorporating spin-crossover subunits, two-directional magnetic chemo-switching is achieved at room temperature. In situ magnetic measurements following guest vapor injection show that most guest molecules transform 1 from the low-spin (LS) state to the high-spin (HS) state, whereas CS(2) uniquely causes the reverse HS-to-LS transition.

Climate variability, innovation and firm performance: evidence from the European agricultural sector

2021

Abstract It is generally accepted that adaptation to climate variability requires a technological advancement strategy. However, the innovation process has received little explicit consideration in this framework. We employ a panel endogenous switching regression model to explore whether and to what extent climate variability affects firm performance through the ability to induce the development of adaptation innovations in key resource-based sectors in Europe during the period 2007–2017. Our findings confirm that the knowledge generation process at the heart of climate change adaptation technologies enhances firm performance, especially for firms in the aquaculture and fishing sub-sectors …

Vendor lock-in problem in cloud storage

2015

Pilvitallennuspalvelut tuovat datan tallentamiseen ennennäkemättömiä etuja ja niiden hyödyntäminen on, sekä yksittäisillä kuluttajilla, että yrityksillä, yleistymässä. Teknologiassa on kuitenkin vielä ongelmia ilman ratkaisua. Turvallisuus-, sekä yksityisyysseikat ovat tunnetuimpia, ja niitä on tutkittu laajalti. Vähemmälle huomiolle on jäänyt, kuinka vaikeaa on palveluntarjoajan vaihtaminen. Palveluntarjoajan vaihtaminen aiheuttaa aina kustannuksia asiakkaalle. Tilannetta, jossa vaihtokustannukset ovat niin suuret, että ne estävät palveluntarjoajan vaihtamisen, kuvataan termillä "vendor lock-in" (toimittajaloukku). Tämän kandidaatintutkielman tavoitteena on kirjallisuuskatsauksen perusteel…

“Oon tehny paljon ostoksia even tho I probably shouldn’t have” : Code-switching in a Finnish Fashion Weblog

2009

  Tämän proseminaaritutkimuksen tarkoituksena oli tutkia koodinvaihtoa suomenkielisessä muotiblogissa: millaisissa tilanteissa koodinvaihtoa ilmeni ja millä kielen eri osa-alueilla. Luemme säännöllisesti muotiblogeja ja osallistuimme syksyllä 2008 Sirpa Leppäsen englannin kielen syventävälle kurssille English as a Global Language, jossa teimme pienimuotoisen tutkielman samasta aiheesta. Mielestämme on tärkeää tutkia koodinvaihtoa blogitekstissä, joka ei täytä kaksikielisen blogin vaatimuksia, mutta joka sivuaa hyvin läheisesti kaksikielistä tekstiä. Blogien tutkimus on keskittynyt lähes pääasiallisesti kaksikielisiin blogeihin, joiden aihepiirit ovat hyvin erilaisia. Emme löytäneet aiempaa …

Does ns2 Really Simulate MPLS Networks?

2008

Multi Protocol Label Switching (MPLS) is being used in many corporate networks and public infrastructures and as a backbone technology of many Autonomous Systems. Because of its importance, what is needed is to find out simulators able to simulate MPLS networks whose results reflect the real environment as much as possible. In this article, we will show real measurements from the Railway Infrastructure Administrator (ADIF, the Spanish railway infrastructure manager) MPLS network and we will compare them with the results obtained by the freeware simulator ns2. We will check the level of reliability provided by the simulator and we will know under which parameters its results will be similar …

Three Stages of Consumers’ Multi-Stage Dichotomic Switching Process Pre-Switch, switch, and post-switch

2021

This research examines why and how consumers switch their mobile phones. We propose a framework that is grounded on decision-making and motivational theories and draws on the findings from a multinational qualitative survey on consumers’ mobile phone switching process. We show that consumers’ pre-switching decisions are affected by push and pull factors, their mobile phone selections are based on utilitarian or hedonic values, and their justifications for switching are based on cognition or affect. Furthermore, we identify two archetypical routes (i.e., cognitive and affective routes) and three conjoint routes that explain the dichotomic switching processes in pre-switch, switch, and post-s…
