Enhancement of immunohistochemical staining
1982
The present paper describes two simple procedures which enhance immunohistochemical staining. One is to cover the sections with a plastic film to keep the serum uniformly distributed and minimize its evaporation. Secondly, rocking of the slides has been introduced, causing the serum to flow back and forth under the plastic film. Using this system, it has been possible to test for the effect of mixing on an immunohistochemical reaction (the demonstration of calcitonin in thyroid C cells). It has been found that mixing definitely enhances the reaction during the first 8 h. No effect of serum volume was observed.
Ecotourism in Bolivia : an ethnographical study of ecotourism impacts in Madidi National Park
2016
Master thesis development management - University of Agder 2016 The concepts of ecotourism are widely defined but it is often used as a marketing instrument in order to promote tourism businesses related to nature. Ecotourism experience a fast growth in world tourism industry and many developing countries are trying to use ecotourism as a tool to achieve sustainable development. Ecotourism provides many beneficiaries to local environments, economies and socio-cultural lives. However, ecotourism may as well have harmful effects on those involved. Still, ecotourism conserves and protects local areas and its people. Madidi National Park in Bolivia has been estimated to be one of the world’s mo…
Advances in Perovskite Optoelectronics: Bridging the Gap Between Laboratory and Fabrication
2020
In 2019, hybrid halide perovskites celebrated their 10th anniversary as a "wonder material" for optoelectronic applications. Although the parent perovskite structures were elucidated in the late 19th century, the seminal work by Miyasaka et al. exploiting organic‐inorganic hybrid halide perovskites sensitizers for visible‐light conversion in solar cells marked the revisit of these materials and has proven to be a game‐changer in this field. Extensive investigations were undertaken to develop new materials (all inorganic and organic‐inorganic hybrids, in the form of films or alternate morphologies) and deposition techniques, explore interfaces and in‐depth characterization, while engineering…
Mobiiliopetuksen käyttömahdollisuuksia : oppilaiden omien mobiililaitteiden käyttö peruskoulun alakoulun opetuksessa
2015
Muutaman viime vuoden aikana mobiililaitteiden käyttö kouluissa on yleistynyt. Tämä on osittain aiheuttanut ristiriitaista keskustelua laitteiden käytöstä opetuksessa. Osa opettajista on ottanut mobiililaitteet opetuskäyttöön innokkaasti. Mobiiliopetuksen mahdollisuuksia ei kuitenkaan ole vielä kovin paljon tutkittu. Tällä tutkimuksella oli tarkoitus selvittää, mitä mahdollisuuksia oppilaiden omat mobiililaitteet tarjoavat opetukseen. Aineiston analyysissa pyrittiin etsimään tietoa siitä, miten ongelma-perustaisen opetuksen menetelmä ja pelillisyys vaikuttavat opetus- ja oppimisprosessissa, kun opiskelumenetelmänä käytetään mobiilioppimista ja oppilaiden omia mobiililaitteita. Tutkimus teht…
Reed canary grass transportation costs – Reducing costs and increasing feasible transportation distances
2009
Abstract Reed canary grass is used in several heat and power plants in Finland and it is estimated that about 70–80 plants could utilise reed canary grass as a co-firing fuel. Long-distance transport of reed canary grass forms a significant share of the production and delivery costs. Reed canary grass can be transported in bales or as loose matter. The density of the matter and shape of the bales influence the load-size and the cost. At present it is impossible to obtain the full load-bearing capacity of a lorry even with bales, and with light bulk matter the obtainable load is less than one-third of the load-bearing capacity of a lorry. By using Orkel local-baler it has been possible to ob…
Utilization of pedicled buccal fat pads for coverage of the lateral relaxing wound: A review of literature and a case series of 15 patients
2018
Background The buccal fat pad (BFP) is an encapsulated mass originated from a specific fat tissue in various volume throughout the life of each person and BFP has been used in various surgeries as a source of useful graft material due to its easy accessibility and rich vascularization. Case Report This report describes fifteen patients who were treated with buccal fat pads (BFP) as a pedicled graft for lateral relaxing wound closure in primary cleft palate surgery. A review of relevant literature is also presented. Results All patients had a mean follow-up of 3.7 weeks with a minimum follow-up time of three weeks and a maximum follow-up of four weeks. All patients who had an uneventful imme…
Almond shell reuse: a viable non-conventional aggregate for sustainable building materials
2022
Bio-based or green architecture is a new way of designing and building in line with the European Green Deal and in light of the Circular Economy principles. The main green approach directs the whole construction life cycle to be eco-sustainable and environmentally friendly from the beginning to the end of the building process. Beyond the use of eco sustainable and highly performing structural materials, new technologies able of reduce the environmental impact of buildings must be used. This paper is aimed at reviewing the possible reuse of bio- wastes of agricultural origin whose massive production generates a number of issues for their treatment and disposal. In particular, this study will…

Challenges in Energy Systems for the Smart-Cities of the Future
2012
In the last years the European Union has actively promoted the renewable energies and the Combined Heat and Power (CHP) also for residential and tertiary buildings. The exploitation of renewable sources and cogeneration seems hampered by the regulatory wall that prohibit for residential, tertiary and commercial buildings the constitution of users clusters. In fact, the unification up to a threshold value of some tens of kVA, at least, can facilitate the installation of renewable energy power plants as solar PV modules or CHP systems (cogeneration) or CCHP systems (tri-generation), overcoming technical and economical barriers and combining several load profiles. The actual distribution syste…
Designing a sustainable regeneration in the outskirt of Agrigento
2016
This paper describes a case of building recovery and sustainable re-use in Sicily, that is the recovery of Villaseta. It is a very degraded neighborhood in the outskirts of Agrigento. The main goal of the redevelopment project is therefore the rebuilding and the environmental regeneration of the neighborhood, using sustainable technologies and tools, with the construction of vegetable gardens and urban gardens, the production of renewable energy and the sustainable recovery of existing buildings. The eco-friendliness of the restoration project is therefore given by the use of garden roofs and vertical gardens. Villaseta will be a real "green lung" able to give greater environmental awarenes…
