Psychrophiles: A source of cold-adapted enzymes for energy efficient biotechnological industrial processes
2021
Biocatalysts are the backbone of bioprocessing industries that are going through a phase of transition with reference to the requirement of extraordinary enzymes for various biochemical processes. This transition is well reported and documented by various researchers through elucidation of different features and applications of mesophilic and thermophilic enzymes. However, there is little information available about psychrophilic enzymes and their involvement in industrial processes. Therefore, understanding the features and functions of psychrophilic enzymes could suggest some of their novel applications in various industries such as food, agriculture, chemicals, pharmaceuticals, and waste…
Challenges to the development of energy performance measurement : a systems thinking approach
2016
Growing global energy consumption and its consequent hindrance to sus-tainable development poses one of the greatest challenges of today. Impro-vement of the end-use energy efficiency is commonly regarded as one of the most basic and significant countermeasures for curbing the rising energy needs. However, it seems that the progress of end-use energy management is currently hindered due to the complexities involved in the measurement and management of energy efficiency. In essence, the lack of appropriate energy performance metrics constitute a gap between the current organizational needs and scientific literature. Furthermore, the current scientific debate has questioned whether ener-gy ef…
Uusiutuvan energian käyttö rakennusten lämmitysjärjestelmissä ja energiatehokkuuden huomioiminen yhdyskuntasuunnittelussa
2013
Ilmastonmuutoksen ja energiakustannusten nousun vuoksi kiinnostus energiatehokkuuteen ja tietoisuus energian säästämisestä sekä kasvihuonekaasupäästöjen vähentämistarpeesta ovat kasvaneet viime vuosina. Kaavoituksen ja maankäytön toteutuksesta johtuvat ympäristövaikutukset ja kasvihuonekaasupäästöt ovat merkittäviä, joten yhdyskuntasuunnittelun oikeanlaisella säätelyllä voi olla huomattavia vaikutuksia päästöjen kehityksen ohjaamisessa ympäristömyönteisempään suuntaan. Myös rakennusmateriaalit sekä lämmitysjärjestelmien valinta vaikuttavat kokonais-energiatehokkuuteen ja päästöihin. Kuopion kaupunki pyrkii tiivistämään yhdyskuntarakennetta ja lisäämään täydennysrakentamista kaavoituksen kei…
Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna
2017
Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…
