Hybrid model for derivation of synthetic unit hydrograph

Splitting the Nash single linear reservoir into two serially connected reservoirs of unequal storage coefficients (one hybrid unit) for a physically realistic response, a hybrid model is introduced for derivation of a synthetic unit hydrograph. Empirical relations are given for estimation of the two storage coefficients from known peak flow (qp) and time to peak (tp). The hybrid model with two ser

Unifying foundations - to be seen in the phenomenon of language

Scientific knowledge develops in an increasingly fragmentary way. A multitude of scientific disciplines branch out. Curiosity for this development leads into quests for a unifying understanding. To a certain extent, foundational studies provide such unification. There is a tendency, however, also of a fragmentary growth of foundational studies, like in a multitude of disciplinary foundations. We s

PCB and DDT in laminated sediments from offshore and archipelago areas of the NW Baltic Sea

Temporal trend studies of PCBs and DDTs in two annually laminated sediment cores from the offshore NW Baltic proper and the Stockholm archipelago demonstrate that studies of laminated sediments are useful tools for detecting time trends of HOCs. The concentration trends of PCBs and DDTs, on a dry weight basis, from the two cores show quite large similarities to trends reported in pelagic biota fro

The Origins of the Synagogue : A Socio-Historical Study

In the first century CE, synagogues existed not only in the land of Israel but in all parts of the Roman Empire where Jews lived. Although incorporating a number of activities, the most characteristic features of this institution were the public reading and teaching of torah, making the synagogue an unparalleled institution in the ancient world. But how, when, where, and why did this unique instit

On the Analysis and Fault-Diagnosis Tools for Small-Scale Heat and Power Plants

Popular Abstract in Swedish Avregleringen av elmarknaden uppmuntrar kraftbolag och oberoende kraftproducenter till att driva sina kraftverksanläggningar på ett marknadsorienterat sätt. För att behålla de ekonomiska marginalerna på plussidan så har de mest populära åtgärderna varit att förbättra elverkningsgraden genom ändringar i hårdvaran samt höja totalverkningsgraden genom till exempel samproduThe deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. combined heat and power (CHP) generation. The bett

Demokrati bortom nationalstaten?

Popular Abstract in Swedish Denna avhandling har två huvudsakliga syften. Det första syftet är att bidra med en fördjupad kunskap kring demokratins begränsningar och möjligheter i en tid av tilltagande globalisering och gränsöverskridande politisk verksamhet. Även om detta syfte i hög grad aktualiserar frågan om den nationella demokratins fortsatta verkansmöjligheter, är fokus ställd på möjligheteThis book has two overarching objectives. Firstly, in an age of increasing globalization and cross-border political activities it seeks to contribute to the debate on the limits and possibilities of democracy in the present and in the future. Even though this objective brings to the fore the issue of democracy in a national context, the main ambition is to examine democratic values and institution

Strategic alliances and trust processes - a study of strategic collaborations between high-technology companies.

Popular Abstract in Swedish Strategiska allianser utgör en tillväxtstrategi som har blivit ett allt vanligare inslag i näringslivet. Även forskningsbidragen kring strategiska allianser har vuxit i omfattning. Dessa forskningsbidrag har i stor utsträckning utgått från ett ekonomiskt/rationellt perspektiv samt fokuserat på de inledande faserna i samarbetet, med inriktning på motiv och val av samarbeThe purpose of this thesis is to develop an increased understanding of strategic alliance processes. A specific aim has been to explore the trust processes involved, and to better understand the dynamics of the strategic alliance processes. The study includes socio-cultural elements and captures both the manager´s and the employee´s perspectives in everyday life. The theoretical discussions were b

Quality of life, morbidity, and mortality after surgical intensive care: a follow-up study of patients treated for abdominal sepsis in the surgical intensive care unit.

OBJECTIVE: To evaluate the long-term outcome of patients treated in the surgical intensive care unit (SICU) for abdominal sepsis. DESIGN: Retrospective study. SETTING: University hospital, Sweden. SUBJECTS: 210 consecutive patients treated for abdominal sepsis in the SICU at Lund University Hospital during the period January 1983 to December 1995. MAIN OUTCOME MEASURES: Background information, mor

Limited spread of penicillin-nonsusceptible pneumococci, Skane County, Sweden

In response to increasing frequencies of penicillin-non-susceptible pneumococci (PNSP), for which the MIC of penicillin was greater than or equal to0.12 mg/L, in Sk (a) over circle ne County, southern Sweden, national recommendations were initiated in 1995 to limit the spread of pneumococci with high MICs (greater than or equal to0.5 mg/L) of penicillin (PRP), especially among children of preschoo

Surface characteristics of group A streptococci with and without M-protein

Twenty M protein-positive and eight M protein-negative strains of group A streptococci were investigated with respect to surface hydrophobicity and amount of lipoteichoic acid (LTA). Surface hydrophobicity as determined in polymer two-phase systems varied substantially between individual strains and there was no correlation to the presence of antiphagocytic M protein. The amount of LTA on the surf

Väst om öst : Kinaforskning och kinasyn under 1800- och 1900-talen

The point of departure of the thesis is the ongoing debate on Orientalism initiated by Edward Said, discussed here in the context of the Western image of China. In the view of Western observers, China has frequently played the role of the Other . Compared to the negative sense that Said and others have given to Orientalism in recent years, as a mode of dominating an arbitrarily defined "Orient", C

Anaerobic glycerol production by Saccharomyces cerevisiae strains under hyperosmotic stress

Glycerol formation is vital for reoxidation of nicotinamide adenine dinucleotide (reduced form; NADH) under anaerobic conditions and for the hyperosmotic stress response in the yeast Saccharomyces cerevisiae. However, relatively few studies have been made on hyperosmotic stress under anaerobic conditions. To study the combined effect of salt stress and anaerobic conditions, industrial and laborato

Predictive factors in pancreatic ductal adenocarcinoma: Role of the inflammatory response.

Objective. Pancreatic ductal adenocarcinoma is a highly lethal disease and most patients are not eligible for curable resection. Estimation of prognosis is essential in order to provide the best individual treatment for patients with pancreatic adenocarcinoma. Prediction of survival by current methods is limited, therefore the objective of this study was to determine possible prognostic factors id

Hydrocarboxylation of olefins using an amphiphilic palladium catalyst, activity and recycling properties NMR identification of some reaction intermediates

The high solubility in acidic solutions of N-bis(N',N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine (N3P) make it a suitable candidate for study and comparison to the more commonly studied trisulfonated triphenylphosphine (TPPTS) ligand in the palladium catalysed aqueous hydrocarboxylation reaction. The catalyst employing N3P shows an inverted regioselectivity compared to the TPPTS

Time-course of the pancreatic changes following long-term stimulation or inhibition of the CCK-A receptor

Cholecystokinin (CCK) reportedly induces both hyperplastic and hypertrophic changes in the pancreas. Blockade of the CCK receptor results in decreased pancreatic secretion and atrophy. The aim of this study was to evaluate the time-course of the effects of stimulation and inhibition of the CCK-A receptor in the rat exocrine pancreas. Male rats had infusion of sulfated CCK-8, the CCK-A receptor ant
