A measurement of the beauty production cross section in ep collisions at a centre-of-mass energy of 319 GeV is presented. The data were collected with the H1 detector at the HERA collider in the years 1999-2000. Events are selected by requiring the presence of jets and muons in the final state. Both the long lifetime and the large mass of b-flavoured hadrons are exploited to identify events contai

Wheat bran (WB), produced worldwide in large quantities as a by-product of the wheat milling industry, constitutes a significant underutilized source of sugars. This paper describes various methods of hydrolyzing the abundant polysaccharides in bran to yield a sugar feedstock suitable for fermentation into bioethanol. Firstly, the starch in the bran was released using amylolytic enzymes. The fibro

A humus soil with a pH of 4.9 was fumigated with chloroform for 5 h, after which only 1% of the initial bacterial activity remained. Half of the fumigated soil was limed to a pH of 7.5. Both the unlimed soil (UL) and the experimentally limed soil (EL) were inoculated with unfumigated (UL) soil or a field-limed (FL) soil with a pH of 6.1. The pH tolerance and activity of each developing bacterial c

The issue of this article is how disability and gender intersect when physically disabled children and youth choose to take long-term part in sports. The data has been derived from participant observations on a sport camp for youth with disabilities, and open-ended interviews with five physically disabled youngster, between 10 and 15 years old, and two table tennis coaches, 19 and 31 years old. Th

The remnants of the walls of three different iron furnaces excavated at Fyllinge 20:436, Snöstorps parish in Halland were studied in order to compare the technology behind their construction. Were they a wholly local enterprise or might itinerant iron production craftsmen be responsible for their construction? The results may be interpreted as a local development of the knowledge of furnace buildi

The impact of antineoplastic drugs on the intestinal microflora was studied in 9 patients with acute leukaemia during chemotherapy and in 5 patients also during chemotherapy-induced neutropenia. Quantitative and qualitative microbiological analyses of faecal samples obtained before and during chemotherapy showed significantly increased counts of Bacteroides spp. in 3/9 patients and, during neutrop

The syntheses of various amino- and hydroxy-substituted dehydrophenylalanine derivatives using the Heck-Jeffery protocol under non-solvent conditions in a ball mill are presented. The influences of electron-withdrawing groups and of the location of the heteroatom substituent relative to the halide are discussed. Suitably substituted ortho-amino dehydrophenylalanine derivatives undergo a cyclizatio

Popular Abstract in Swedish Begreppet systemförvaltning började användas i början på 1970-talet. Ämnet har betydelse ur flera perspektiv. Systemförvaltningskostnaderna är som regel betydligt större än systemutvecklingskostnaderna, vilket kan veri¬fieras med flera undersökningar gjorda i olika länder och under en tidsperiod omfattande ett par decennier. Det vetenskapliga intresset för systemförvaltThe term Software Maintenance was coined in the early 1970s. The subject has significance from several points of view. The costs associated with software maintenance are as a rule considerably higher than what the system cost to develop, which is borne out by many studies conducted in different countries over a period of twenty years. Scientific interest in software maintenance, on the other hand,

We report on the observation of excited states in the niobium isotope with masses 84, 85 and 86. These nuclei lie in the shape transition region known to occur in nuclei with 35 less-than-or-equal-to Z less-than-or-equal-to 40 and N = 45. Unambiguous identification was achieved by detecting gamma-rays in coincidence with mass-separated recoils produced in heavy-ion fusion reactions. Rotational ban

Objective: To conduct systematic long-term follow-up (LTFU) of patients in the Prevention of Relapses and Disability by Interferon beta-1a Subcutaneously in Multiple Sclerosis ( PRISMS) study to provide up to 8 years of safety, clinical and MRI outcomes on subcutaneous (SC) interferon (IFN) beta-1a in relapsing-remitting multiple sclerosis (RRMS). Methods: The original cohort of 560 patients was r

We have used transient photoinduced absorption on femtosecond to nanosecond time scales as well as delayed fluorescence up to microseconds to study the photogeneration and recombination of charges in thin films of the alternating polyfluorene copolymer poly[2,7-(9,9-dioctylfluorene)-alt-5,5-(4('),7(')-di-2-thienyl-2('),1(') ,3(')-benzothiadiazole)]. We interpret the results using a coupled rate eq

The purpose of this study was to observe how public health nurses perform blood pressure measurement. Structured observations were made of 21 randomly selected public health nurses while they performed three blood pressure measurements. The public health nurses used an overall correct method for blood pressure measurement. Five nurses out of 21 used the Tri-cuff but the soft cuff was most frequent

Contractile responses to phenylephrine and high-K+ were investigated in vitro in microvascular preparations from the rat medial plantar artery, a branch from the saphenous artery, obtained after short-term denervation in vivo. Two groups of animals were studied: (1) animals undergoing surgical resection of the saphenous nerve, and (2) animals undergoing surgical resection of both the sciatic and s
