Slutreplik. Per-Åke Sahlberg skriver engagerat om att det finns mer än jordbruk som påverkar vattenkvalitet. Han har helt rätt. Eftersom vatten ständigt är i rörelse och helt gränsöverskridande kommer alla aktiviteter som sker att påverka vattenkvaliteten – såväl antropogena som naturliga. Men prioriteringar av var insatserna måste ske görs sällan. Att påstå att avloppshanteringen är det största p

Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface of arbitrary material, ie the radome, is analyzed. The transformation is based on a full vector surface integral representation that relate

Water harvesting and artificial recharge has been a traditional solution to water scarcity problems in the arid and semiarid Middle East for thousands of years. These techniques are increasingly being encouraged and at present there has been a renewed interest to find improved methods for water harvesting in many arid countries. The objective of the present study was to evaluate the performance an

A growing mass of research contributes to our understanding of how cultural and environmental systems coevolve, whereby environmental systems reflect the characteristics of social/cultural systems and vice versa. Biodiversity and cultural diversity are intrinsically related in the processes of coevolution that generate change in the patchwork quilt of cultural and natural landscapes. These process

This paper analyzes the I/Q imbalance effect of direct-conversion receiver in wide-band wireless communication system and sets up frequency-selective I/Q imbalance model for ultra-wide band system. We design a new training sequence based on extra phase rotation and propose an estimation algorithm using diversity message introduced by I/Q imbalance during the demodulation process. Theoretical analy

Popular Abstract in Swedish Bröd har varit ett av våra viktigaste baslivsmedel sedan antiken (700 f.Kr. – 400 e.Kr.) och kommer med all sannolikhet också fortsätta att vara en viktig del av vår föda även i framtiden. Det i Sverige rekommenderade dagliga intaget (RDI) av kostfiber är 25-35g. Utav dessa kostfibrer bör hälften komma från bröd (33%) och andra spannmålsprodukter (17%), vilket motsvararBread products are one of the most common and important foods in our daily diet, and have been since ancient times. Although it has a long history and comes in many variations, the staling phenomenon of bread is still not fully known. Staling is a complex phenomenon that includes all the physical and sensorial changes occurring in bread during storage. To gain a better understanding of staling, di

Wastewater treatment processes are inherently dynamic because of variations in the influent flow rate, concentration, and composition. The adaptive behaviour of the microorganisms further emphasizes this fact. Mathematical models and computer simulations are essential to describe, predict, and control the complicated interactions of the processes. Any attempt to model all details of the various re

n this paper a disturbance in the western part of the Swedish power system, 1997, January 1, is studied. Two large nuclear units tripped due to a short circuit in a substation. The purpose of this paper is to study the damping features of power oscillations by using synchronised measured frequency deviations between generators and the mean system frequency. The measurements are based on GPS (Globa
