Bis(phosphinidene)-capped triiron carbonyl clusters, including electron rich derivatives formed by substitution with chelating diphosphines, have been prepared and examined as proton reduction catalysts. Treatment of the known cluster [Fe3(CO)9(µ3-PPh)2] (1) with various diphosphines in refluxing THF (for 5, refluxing toluene) afforded the new clusters [Fe3(CO)7(µ3-PPh)2(κ2-dppb)] (2), [Fe3(CO)7(µ

Roads are subjected to traffic loads and varying climate conditions that eventually lead to different types of damage. Moisture in asphalt is one of the major causes of premature failure in asphalt pavements. In addition, moisture in the unbound layers and temperature in the asphalt concrete (AC) layers affect the structural response of pavements under loading, such as the tensile strain at the boRoads are subjected to traffic loads and varying climate conditions that eventually lead to different types of damage.

OBJECTIVE--The aim was to study the association between personal factors and physical and psychosocial work environment factors and disorders of the neck or upper limbs among women in the fish processing industry. METHODS--A cross sectional study was performed on 206 women in the fish processing industry and 208 control women. Several physical and psychosocial work environment factors were evaluat

Background: IgE-mediated allergy is associated with immunoglobulin heavy constant G chain (Fcγ) (GM) genes (IGHG) on chromosome 14q32.3. Investigation of the alternative GM allotypes of γ3, γ1 and γ2 chains has disclosed new structural and functional IgG subclasses and B-cell variants, with possible effects on childhood asthma. Objective: To investigate different IGHG (GM) gene complexes in a

We studied the prevalence of musculoskeletal pain and its impact on performance in orchestra musicians and in a reference group of actors, who share the mental stress in a performance situation, but without having the physical work load from an instrument. Swedish musicians (n = 103) from symphony and chamber orchestras and actors (n = 106) participated in a cross-sectional questionnaire study. Mu

Introduction: Women and underrepresented groups in medicine hold few academic leadership positions in the field of hematology/oncology. In this study, we assessed gender and race/ethnicity representation in editorial board positions in hematology/oncology journals. Materials and Methods: Editorial leadership board members from 60 major journals in hematology and oncology were reviewed; 54 journals

En stor del inom utvecklingen av nya produkter är test och validering. Denna process kräver användning av dyra och stora testsystem. På grund av dessa faktorer är det viktigt att maximera användningen av dessa testsystem. Till följd av detta har ett övervakningssystem utvecklats av test- och validerings-avdelningen på BorgWarner i Landskrona som kan läsa driftstatus (Till exempel på och av) av visA large part of developing products is the testing and validation of the new products. This process requires expensive test systems and a great deal of time and space. Because of these factors it is very important to maximize the usage of the test systems. Therefore, a monitoring system has been developed by the test and validation department at BorgWarner Landskrona that can read the operational

Radiolabelled monoclonal IgM rheumatoid factors, four from patients with type II essential cryoglobulinaemia and one originating from a patient with rheumatoid arthritis, were tested for binding to group A, B, C and G streptococci and Escherichia coli. Two of the preparations exhibited different binding patterns for the streptococci, whereas the remaining three were not reactive. The binding of on

Indigenous rituals escorted Evo Morales throughout his first years as president of Bolivia. The art and the ritual practices of the yatiri, the Aymara healer and ritual specialist, are going through interesting transformations entering new political spaces of power. But which role does this therapeutic knowledge and ritual practice actually play in the present political process and how should this

Popular Abstract in Swedish Elektriska pulser (PEF) är en nyligen introducerad icke-termisk livsmedelsprocess, som har en karakteristisk påverkan på cellmembranet. PEF-behandling innebär att livsmedlet utsätts för korta och upprepade pulser emellan en anod och en katod. Det huvudsakliga resultatet av denna process är en skada på cellmembranet, som leder till bildandet av antingen tillfälliga ellerA pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. The main result of this process is the disruption of the cell membrane leading to the formation of either temporary or permanent pores

Combinatorial screening methodology has been employed to select new affinity specific ligands to bilogical and artificial receptors. The screening methodology, in particular screening of combinatorial phage display peptide libraries against target molecules differing in function and shape, is focused upon. A linear combinatorial phage display hexapeptide library has been used to select novel pept

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Antikroppar, även kallade immunoglobuliner, är proteiner som utgör en viktig del i vårt försvar mot infektioner genom att de kan binda och neutralisera ämnen som uppfattas som främmande, t ex bakterier, virus eller produkter som produceras av dessa organismer. Antikropparna består av en antigen-bindande variabel del som binder till deMany bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. Protein G found on group C and G streptococci has affinity for constant regions of IgG heavy chains, whereas protein L found on Peptostreptococcus ma

The aim of this thesis is to assess whether the Second Amendment to the United States (U.S.) Constitution prevents the U.S. from adopting an Australian style of gun control. In the aftermath of the Port Arthur massacre in 1996, Australia completely reformed its gun control legislation by enacting strict and uniform gun control laws under the National Firearms Agreement (NFA). While Australia’s gun

Popular Abstract in Swedish Tillgången till rent vatten är avgörande för människans överlevnad, tillgång till vatten kan förbättra den allmänna hälsan och därmed också vår fortsatta existens på jorden. Naturkatastrofer eller mänsklig påverkan genom t.ex. industrin kan dock resultera i att vattenkällor, tidvis eller permanent, blir förorenade med miljögifter som hindrar människans konsumtion av renThe lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. Inorganic pollutants or toxic metal ions such as arsenic and cadmium are of special concern since these are persistent and accumulate
