Water resources management through rainwater harvesting in arid area

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

Co-evolution under globalization : boundary lessons from Kinmen Island

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

Design of new training sequence and estimation scheme for frequency dependent I/Q imbalance in MB-OFDM based UWB systems

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

Staling and Starch Retrogradation in Speciality Bread

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

On the Verifiability of the Activated Sludge System Dynamics

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

Damping of Generator Oscillations using Phasor Measurement Units and Breaking Resistors

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

Norms and narratives in international law

How might we understand the norms and normativity of international law? This is a conversation between international law and theology on the meaning of norms and normativity in international law - as seen from inside the discipline of international law.

Phonology of a southern Swedish idiolect

In this egocentric article I describe briefly the segmental phonology of my own southern Swedish idiolect. I grew up in Getinge in central Halland, about 20 km north of Halmstad, speaking a regional variant of southern Standard Swedish. Although my dialect has certainly changed somewhat after I moved to Lund in 1964 at the age of 20, I believe that I still retain the basic pronunciation of vowels
