The Impact of Green Roofs on the Parameters of the Environment in Urban Areas—Review

2019

This study presents the results of a review of publications conducted by researchers in a variety of climates on the implementation of ‘green roofs’ and their impact on the urban environment. Features of green roofs in urban areas have been characterized by a particular emphasis on: Filtration of air pollutants and oxygen production, reduction of rainwater volume discharged from roof surfaces, reduction of so-called ‘urban heat islands’, as well as improvements to roof surface insulation (including noise reduction properties). The review of the publications confirmed the necessity to conduct research to determine the coefficients of the impact of green roofs on the environment in the city c…

Truncated recombinant light harvesting complex II proteins are substrates for a protein kinase associated with photosystem II core complexes

1998

AbstractPrevious studies directed towards understanding phosphorylation of the chlorophyll a/b binding proteins comprising light harvesting complex II (LHC II) have concentrated on a single phosphorylation site located close to the N-terminus of the mature proteins. Here we show that a series of recombinant pea Lhcb1 proteins, each missing an N-terminal segment including this site, are nevertheless phosphorylated by a protein kinase associated with a photosystem II core complex preparation. An Lhcb1 protein missing the first 58 amino acid residues is not, however, phosphorylated. The results demonstrate that the LHC II proteins are phosphorylated at one or more sites, the implications of wh…

Model research on the influence of green roofs on environmental parameters in urban agglomerations

2018

The intensive development of urban agglomerations in Poland and other European countries has rendered the growth of biologically active areas more important with respect the quality of the urban environment. Taking the rapidly rising prices of plots in city centers into consideration, it is worth noting the vast surfaces of building roofs that can be used as biologically active areas. The term green roof is to be understood as an open, overgrown surface on a multilayer roof of a building. Green roofs can only be made on a planar surface with an inclination of 2% to 30%. In accordance with the type of usage, construction factors and maintenance requirements, green roofs are typically defined…

A Systematic Review of Cost-effectiveness Evidence of Endoscopic Saphenous Vein Harvesting: Is it Efficient?

2011

Objective: Greater saphenous vein harvest for coronary and lower extremity bypass requires the longest incision of any surgical procedure. Endoscopic vein harvest allows better results in some clinical variables compared to open harvesting techniques. The objec- tive of this study is to present the results of a systematic review of the scientific evidence about the efficiency of endoscopic saphenous vein harvest. Methods: We performed a systematic review in the bibliographical databases Pubmed, National Health Service Economic Evaluation Database, and NHS Health Technology Assess- ment Database. The search strategy was "endoscopic AND harvesting", in the period January 1970eDecember 2009. R…

Correlation of preoperative imaging characteristics with donor outcomes and operative difficulty in laparoscopic donor nephrectomy

2019

This study aimed to understand the relationship of preoperative measurements and risk factors on operative time and outcomes of laparoscopic donor nephrectomy. Two hundred forty-two kidney donors between 2010 and 2017 were identified. Patients' demographic, anthropomorphic, and operative characteristics were abstracted from the electronic medical record. Glomerular filtration rates (GFR) were documented before surgery, within 24 hours, 6, 12, and 24 months after surgery. Standard radiological measures and kidney volumes, and subcutaneous and perinephric fat thicknesses were assessed by three radiologists. Data were analyzed using standard statistical measures. There was significant correlat…

Outcome measurements following palatal soft tissue graft harvesting: A review

2021

Background Free gingival graft (FGG) and connective tissue graft (CTG) are two of the most commonly techniques performed in periodontal and peri-implant plastic surgery. Although several outcome measurements have been proposed for evaluation of palatal wound healing and patient morbidity, a comprehensive review about these variables is lacking. The objective of this review is to present comprehensive information about outcome measurements related to postoperative palatal wound healing and postoperative patient-reported morbidity after FGG or CTG procedures. Material and methods An electronic search of English language dental literature in the Medline database via PubMed access was conducted…

Nanotechnologies and Radiation Processes : Online meeting (Riga, 3–4 February 2022)

2022

The Institute of Chemical Physics of the University of Latvia held an online conference session “Nanotechnologies and Radiation Processes” on the 3rd and the 4th of February of 2022. The session was organised within the framework of the 80th International Scientific Conference of the University of Latvia. The Book of Abstracts of the session focuses on such topics as energy harvesting, storage processes, development of functional materials, radiation processes in solids, growth, and fundamental studies of topological insulator nanostructures.

Turvetuotannon sosiaalisen toimiluvan menetys Saarijärven reitillä

2018

Following the 1970s oil crisis the search for alternative energy sources intensified in Finland. As a result, peat harvesting from peat bogs was launched programmatically. This included peat bogs around the Saarijärvi waterway in central Finland, consisting today about 50 peat harvesting sites. As in a number of cases, these peat harvesting operations are opposed by the local residents, who insist that peat harvesting is spoiling the waters, and thus damaging recreational activities like fishing, swimming, and the enjoyment of nature. The aim of our study was to investigate the situation in greater detail by eliciting local residents’ experiences. In the fall of 2015 a questionnaire was sen…

IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security

2018

Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…
