This is a work for solo violin improvisation, four radios, four radio transmitters, and a four track fixed-media sound collage made from field recordings and eurorack synthesizers. This performance was at the one-night festival Sonotopia, put on by those of us who took the Sound Art as Critical Practice course at Stockholm University for the Arts in January of 2019. The film was made by Girilal Ba
Fixed Media, Mixer DIffusion, Violin and Voice created for irregular 47.2 channel system. 2018. PLEASE NOTE this is a Headphone version of the piece. It will not play properly in speakers. A reduced, multi-track version of the tape part is available from the composer on request.
Deuterium quartet (Bruno Andersen - vevlira, Lisa Gerholm - Nyckelharpa, Fredric Bergström - vevlira, Katt Hernandez - F# violin) playing a composition/improvisation structure in Mimerlaven, at the Norberg festival. Tis work was made collaboratively.
Deuterium (Lisa Gerholm - Nyckelharpa, Bruno Andersen - vevlira and Katt Hernandez - F# violin) performing a composition/improvisation in the Dome of Visions when it was at KTH in Stockholm. This work was made collaboratively.
Deuterium (Bruno Andersen - vevlira and Katt Hernandez - F# violin) performing a composition/improvisation at a former industrial building that was about to be rebuilt as condominiums at Virkesvägen 3 in Stockholm. This work was made collaboratively.
This is a collaborative composition/improvisation made for organist Karin Johansson. Since Johansson combined her work with me with a project she was doing about choral preludes, both recordings feature segues between Ghost Prelude and some of the choral preludes she was working on. This is a collaborative work.
Ghost Installation: Tomteboda is one of several "Ghost Installation" compositions in the project. Using small, consumer grade speakers and looping sound collage files, these sound installation compositions are placed in multichannel arrays into the sites they address. Ghost Installation: Tomteboda was carried out at the site of a former community garden, outside the Tomteboda post terminal buildin
Ghost Installation: is one of several "Ghost Installation" compositions in the project. Using small, consumer grade speakers and looping sound collage files, these sound installation compositions are placed in multichannel arrays into the sites they address. This installation was created for the one day Sonotopia festival, put on by students in the Sound Art as Critical Practice course at Stockhol
Ghost Installation: Internationella biblioteket is one of several "Ghost Installation" compositions in the project. Using small, consumer grade speakers and looping sound collage files, these sound installation compositions are placed in multichannel arrays into the sites they address. This piece was installed beside the former site of the Stockholm International Library. The library was closed in
New antimicrobial agents are needed to address the ever-growing risk of bacterial resistance, particularly for methicillin- and vancomycin-resistant Staphylococcus aureus (S. aureus). Here, we report a class of bile acid oligomers as facial amphiphilic antimicrobials, which are noncovalently fabricated by cholic acid (CA) and deoxycholic acid (DCA) with polyamines (e.g., diamines, diethylenetriami
Can wealth shocks have intergenerational health consequences? We use the partial compensation slaveholders received after the 1834 slave emancipation in the British Cape Colony to measure the intergenerational effects of a wealth loss on longevity. We find that a greater loss of slave wealth shortened the lifespans of the generation of slaveholders that experienced the shock albeit these effects are
This article explores how and why some online protests manage to gain digital resource abundance, that is, mobilising large numbers of people and attracting wide interest and support in a short space of time. The study focuses on the case of the Swedish Petrol Uprising 2.0 which after a few months managed to mobilise 630,000 members on Facebook. The article expands established theories on online m
Background and Aims: Compulsive sexual behavior (CSB) is characterized by a persistent pattern of failure to control sexual impulses, resulting in repetitive sexual behavior over a prolonged period that causes marked discomfort in personal, family, social, school, work or in other functional areas. The evolution of the worldwide incidence of this disorder warrants further studies focused on examin
Food and Agriculture Organization (FAO) dual crop coefficient (FAO-2Kc) is one of the widely used formulation to estimate soil evaporation (E) due to its operationality and simplicity. The FAO-2Kc method could explicitly distinguish the contribution of E and plant transpiration, separately. However, systematic and random uncertainty in E observations still exist. In this vein, this paper attempts
Accurate estimation of evapotranspiration (ET) is of crucial importance in water science and hydrological process understanding especially in semi-arid/arid areas since ET represents more than 85% of the total water budget. FAO-56 is one of the widely used formulations to estimate the actual crop evapotranspiration (ETc act) due to its operational nature and since it represents a reasonable compro
This study aims to investigate the effects of an optimized sowing calendar for wheat over a surface irrigation scheme in the semi-arid region of Haouz (Morocco) on irrigation water requirements, crop growth and development and on yield. For that, a scenario-based simulation approach based on the covariance matrix adaptation–evolution strategy (CMA-ES) was proposed to optimize both the spatiotempor
Monitoring agricultural crops is of paramount importance for preserving water resources and increasing water efficiency over semi-arid areas. This can be achieved by modelling the water resources all along the growing season through the coupled water–surface energy balance. Surface albedo is a key land surface variable to constrain the surface radiation budget and hence the coupled water–surface e
Accurate seasonal forecasting of cereal yields is an important decision support tool for countries, such as Morocco, that are not self-sufficient in order to predict, as early as possible, importation needs. This study aims to develop an early forecasting model of cereal yields (soft wheat, barley and durum wheat) at the scale of the agricultural province considering the 15 most productive over 20
In semiarid areas, the climate is characterized by strong spatiotemporal variability while the meteorological ground network is often very sparse. In this context, the spatial distribution of meteorological variables is thus a real issue for watershed hydrology, agronomy and the study of surface–atmosphere retroaction in these regions. The aim of this study is twofold: (1) to evaluate and to adapt
Crop evapotranspiration (ET) is a fundamental component of the hydrological cycle, especially in arid/semi-arid regions. The FAO-56 offers an operational method for deriving ET from the reduction (dual crop coefficient Kc) of the atmospheric evaporative demand (ET0). The dual coefficient approach (FAO-2Kc) is intended to improve the daily estimation of ET by separating the contribution of bare soi
