Three new diarylheptanoids, (4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-4,6-dien-3-one, letestuianin A (1), (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-4,6-dien-3-one, letestuianin B (2), and 1,7-bis(4-hydroxyphenyl)heptan-3,5-dione, letestuianin C (3), as well as the known (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxyphenyl)hepta-4,6-dien-3-one (5) were isolated f
The energy transfer within a series of Zn-porphyrin appended dendrimers was studied by means of time-resolved fluorescence anisotropy. We show that the energy transfer process between the Zn-porphyrin units in the dendrimers is limited to a maximum of four porphyrin units. At 200 K, the energy transfer process takes place on a 100-ps time scale, and can be modeled by Forster theory. Our results at

Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters. The research is presented in the form of five sc
This study presents a simple and rapid solvent exchange procedure using a hollow fiber. Antioxidants (Irganox 1010, Irganox 1076 and Irgafos 168) and solvents such as tetrahydrofuran (THF), carbon tetrachloride and toluene were selected as model compounds and sample solvents, respectively. After injection of the sample solution into the hollow fiber and solvent evaporation, the precipitated analyt
Multiphase clock generators are conventionally implemented with a feedback loop. This paper presents a non-feedback approach to generate multiphase clocks. A simple architecture of direct phase interpolation is proposed, in which the edges of two phase-adjacent signals are used to control the discharge (or charge) of two capacitors respectively, producing time-overlapped slopes. A resistor chain c
The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision is required Before the measurements, the fibre samples were dried in an oven at
Rapporten beskriver en studie som syftat till att undersöka och beskriva tre typer av Probiks fuktindikatorer från Alfasensor AB. De olika typerna är Probiks CO, BI och HU. Studien är delvis utförd på laboratorium och delvis i fält på en byggarbetsplats. I rapporten har även erfarenheter från mätningar i befintliga byggnader sammanställts. I studien har en rad experimentella försök av indikatorern
Målet med projektet var att analysera problem med arbete i kyla i mjölkproduktionsanläggningar vad gäller förekomst, frekvens och skaderisk samt att föreslå åtgärder för förbättringar. Projektet bestod av två delar: Del 1. En fältstudie, som genomfördes dels i Uppsalatrakten, dels i Västerbottens län. Del 2. En enkätstudie, riktad till Lantbrukshälsans medlemmar i norra regionen. Fältstudierna omfThe aim of the project was to analyse problems with cold when working in dairyfarms with respect to prevalence, frequency and risk for injuries and to propose measures for improvements of thermal conditions. The project comprised two parts: a field study and a questionnaire survey. The field studies were performed at seven dairy-farms in the Uppsala region and six dairy-farms in the northern regio
For a random walk with negative mean and heavy-tailed increment distribution F, it is well known that under suitable subexponential assumptions, the distribution pi of the maximum has a tail pi(x, infinity) which is asymptotically proportional to integral(x)(infinity)F(y,infinity) dy. We supplement here this by a local result showing that pi(x, x + z] is asymptotically proportional to zF(x,infinit
Medeltidshandskrift 14, the so called Liber scole virginis, is the oldest existing song book of the Cathedral of Lund. It has been given much attention this year in connection with the 900th anniversary of the archdiocese of Denmark. The codicological analysis of this manuscript tells an interesting story about the development of the Marian cult in Lund.
Several converging lines of contemporary evidence suggest that weakness presents a more serious compromise to movement function in poststroke hemiplegia than spasticity. This review examines the clinical and functional phenomena of weakness in poststroke hemiplegia, currently available evidence identifying physiologic substrates contri-buting to weakness, and reports of early investigations involv
Entrepreneurship is considered a central force of economic development, as it generates growth and serves as a vehicle for innovation and change., Tourism is one of the economic sectors in which a great degree of involvement is needed by the entrepreneurial sector: diversification of tourism products and services is needed to cope with increased demand for new types of tourism needs. These include
BACKGROUND: Cytotoxic eosinophil granule proteins are considered important in the pathogenesis of inflammatory airway diseases, including asthma, rhinitis, and polyposis. However, little is known about the mechanisms involved in the deposition of these tissue-damaging granular products in vivo. OBJECTIVE: We sought to determine the occurrence of degranulating eosinophils, those with morphologic ev
Conclusions. The results confirm that tumour stage influences the risk of recurrence/second primary tumour (SPT). High-risk human papillomavirus (HPV)-infected patients have a significantly higher risk of recurrence/SPT compared with high-risk HPV-negative patients. High alcohol consumption was associated with a higher risk of recurrence/SPT. In this study, the competing risk of death in intercurr
OBJECTIVE: To evaluate newly developed equations predicting relative glomerular filtration rate(GFR) in adult Swedish Caucasians and to compare with the Modification of Diet in Renal Disease(MDRD) and Mayo Clinic equations using enzymatic and zero-calibrated plasma creatinine assays. MATERIAL AND METHODS: GFR was measured with iohexol clearance adjusted to 1.73 m(2). One population sample (n=436/L
