In this study, the results from simulations of two sets of a 1/2 scale ISO room (ISO 9705) experiments are presented. In the experiments, heptane in a tray was burned in the middle of the room. Five models with various levels of complexity and geometric detail are used. The comparisons between simulations and experiments show that the fourth model provides the most accurate results with deviation

Mangrove forests are highly productive and vital ecosystems within the tropical and subtropical latitudes. They are considered biodiversity hot spots and hosts ha vast variety of species, both terrestrial and marine, and they are also found to be one of the most productive carbon pools in the world. Mangroves additionally provide coastal communities with timber but also important shelter from tsun

The question of Palestine remains one of the most salient dilemmas for policymakers and scholars interested in Middle Eastern and international affairs due to its protracted nature, the many structural limitations it is subject to, and the human and material costs it continues to generate. This thesis explores the current opportunities for regional cooperation in the MENA region around the Palesti

25 september 2025 09:30 till 18:00 | Seminarium The symposium brings together a range of artistic practices and perspectives in order to interrogate how live performance engages with the here and now. What happens in moments when the now exceeds a possible response, the urgency is greater than the means, when words lose meaning and are unable to perform? What is performance transformed to then? Du

Cities are the pinnacle of human change to the environment, creating unique types of ecosystems which present many challenges to local organisms: habitat fragmentation, introduced species, and various pollutants. Being crucibles of anthropogenic effects, urban ecosystems offer opportunities to understand how humans impact nature. Moreover, since a majority of the world’s population resides in citiCities are the pinnacle of human change to the environment, creating unique types of ecosystems which present many challenges to local organisms: habitat fragmentation, introduced species, and various pollutants.

Popular Abstract in English Colors have always been part of human life and culture. Today natural pigments have been substituted by synthetic dyes that usually end up threatening nature itself by polluting the environment. To what extent can we use chemistry and biology to minimize the environmental impact of the textile industry? During the dyeing process a certain amount of dye, 2 to 50 percent,Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. New technologies have been developed in the last decades and in particular Advanced Oxidation Processes (AOPs)

Background/aims Anterior segment ischaemia (ASI) is a rare but serious complication of strabismus surgery, which may be caused by damage to the anterior ciliary arteries that run along the rectus muscles. To avoid ASI, clinical praxis is to operate on a maximum of two rectus muscles at a time. The aim of this study was to perform a detailed study of the contribution of the four ocular rectus muscl

27 oktober 2025 10:00 till 12:00 | Seminarium The world is crossing the 1.5°C global warming limit, perhaps exceeding 2°C soon after. What is to be done when these boundaries, set by the Paris Agreement, have been passed? In the overshoot era, schemes proliferate for muscular adaptation or for new technologies to turn the heat down at a later date by re­moving carbon dioxide from the air or blocki

Groundwater hydraulics and aquifer processes are largely investigated using techniques that involve some kind of borehole test pumping. Such techniques are well established in the engineering and scientific community but are resource demanding. Time series analysis offer a collection of alternative methods that can be used to evaluate groundwater processes like recharge by using natural groundwate

"Principal Components Regression" (PCREG), also sometimes called "biased regression methods" is used to model data with highly correlated explanatory variables. This well-known method has been discussed by multiple previous authors (Marquardt 1970, Hoerl and Kennard 1970, Lott 1973, Hawkins 1973, Webster, Grace and Mason 1974, Hoerl, Kennard and Baldwin 1975, Marquardt and Snee
