Institutional perspectives in transition : research groups’ profiles and embeddedness in organisational and national context

2019

Research into differentiation and profiling of knowledge producing institutions through the lenses of institutional logics and field embeddedness have proliferated in recent years. By discussing this process in the context of research groups, as those basic units in which knowledge production epistemically and practically takes place, this article offers a contribution to the theoretical discussion on organisational differentiation. Based on a small-N comparative case study of research groups operating in different national and organisational contexts on a single, highly competitive and interdisciplinary applied sciences field, nanosciences, the article proposes research group profiles as h…

Negatīvā spiediena terapijas ietekme uz organisma homeostāzi

2016

Literatūras norāda uz to, ka negatīvā spiediena brūču terapija sekmē ātrāku audu defekta dzīšanu. Šīs terapijas iespējamais blakusefekts var būt organisma proteīnu zudums. Vidējais kopējā proteīna līmenis eksudātā ir 57 g/L, bet albumīna līmenis ir 21 g/L. Terapija specifisks proteīna zudums var tikt aprēķināts reizinot seruma albumīnu ar 0.3. Literatūras datiem atbilstošu olbaltumvielu uzņemšanu, kas sastāda 1.5g/kg/dienā ir attiecīgi jāreizina ar 1.3, rezultātā iegūstot 2.0 g/kg/dienā. Oriģinālās savākšanas sistēmas tika pielietotas veiksmīgi, un laboratoriskie protokoli attiecībā pret eksudātiem tika paplašināti. Šis pētījums ir ieguldījums sarežģītā zinātnē par brūču dzīšanu, prasībām p…

DigiTala research project : automatic speech recognition in assessing L2 speaking

2020

In this article, we discuss the premise of assessing oral language skills with the help of automatic speech recognition. We present the main goals and working methods in DigiTala project (2019–2023) – a research project between University of Helsinki, Aalto University and University of Jyväskylä that aims at developing a digital tool for assessing and practicing oral language skills. Ultimately, this digital tool would enable implementing tasks measuring oral skills into the language tests of the Matriculation Examination. nonPeerReviewed

Extraction Methods of Essential Oils From Herbs and Spices

2017

International audience; This chapter describes both conventional and non‐conventional extraction methods of essential oils (EOs) from herbs and spices. Although hydrodistillation, steam distillation and solvent extraction are the most applied methods, several non‐conventional technologies have been evaluated, especially in respect to EO recovery, and a great potential has been attributed to these non‐conventional methods. For instance, ultrasound, microwave, supercritical fluid, pulsed electric fields, ohmic‐heating and microwave (MW) extraction techniques applied alone or combined with other techniques are potent tools to obtain EOs in a 'green' way from natural resources such as aromatic …

Enforcing trust for execution-protection in modern environments

2016

The business world is exhibiting a growing dependency on computer systems, their operations and the databases they contain. Unfortunately, it also suffers from an ever growing recurrence of malicious software attacks. Malicious attack vectors are diverse and the computer-security industry is producing an abundance of behavioral-pattern detections to combat the phenomenon. Modern processors contain hardware virtualization capabilities that support implementation of hypervisors for the purpose of managing multiple Virtual-Machines (VMs) on a single computer platform. The facilities provided by hardware virtualization grant the hypervisor control of the hardware platform at an effective privil…

The state-of-the-art of collaborative technologies for initial vocational education : a systematic literature review

2018


 
 
 Future workplaces require collaboration skills in which members of different work communities use technologies to solve complex problems. Vocational education and training (VET) programs need to meet the challenge to prepare students to be part of a competent workforce. Particularly initial vocational education is under pressure to develop learners’ collaboration skills and abilities. To date, however, no attempt has been made to perform a comprehensive review of the use of computer-supported collaborative learning (CSCL) technologies across different vocational education settings to account for contextual factors of VET. In this systematic review, 26 published studies …

Surrogacy relationships: a critical interpretative review

2020

Abstract Based on a critical interpretative review of existing qualitative research investigating accounts of ‘lived experience’ of surrogates and intended parents from a relational perspective, this article proposes a typology of surrogacy arrangements. The review is based on the analysis of 39 articles, which belong to a range of different disciplines (mostly sociology, social psychology, anthropology, ethnology, and gender studies). The number of interviews in each study range from as few as seven to over one hundred. Countries covered include Australia, Canada, Greece, India, Iran, Israel, Italy, Mexico, Norway, Russia, Sweden, UK, Ukraine, and the USA. Most studies focus only on surrog…

Relay Catalysis: Enantioselective Synthesis of Cyclic Benzo-Fused Homoallylic Alcohols by Chiral BrOnsted Acid-Catalyzed Allylboration/Ring Closing M…

2013

Six- and seven-membered benzo-fused cyclic homoallylic alcohols can be readily synthesized by a tandem chiral BrOnsted acid-catalyzed allyl (crotyl)boration/ring closing metathesis sequence performed under orthogonal relay catalysis conditions. Excellent enantio- and diastereoselectivities are obtained in most of the cases. In addition, the parent crotylboration/RCM process is also described. The required substrates, ortho-vinylbenzaldehydes, are readily available in one step from commercially available starting materials. Both catalysts and reactants are also available from commercial suppliers. The reaction shows broad functional group compatibility and is also suitable for heteroaromatic…

Defects in III-N LEDs: experimental identification and impact on electro-optical characteristics

2022

III-N light-emitting-diodes (LEDs) are subject of intense investigations, thanks to their high efficiency and great reliability. The quality of the semiconductor material has a significant impact on the electro-optical performance of LEDs: for this reason, a detailed characterization of defect properties and the modeling of the impact of defects on device performance are of fundamental importance. This presentation addresses this issue, by discussing a set of recent case studies on the topic; specifically, we focus on the experimental characterization of defects, and on the modeling of their impact on the electro-optical characteristics of the devices.
