One of the central questions in theoretical particle physics, since already several decades, has been that of "masses and mixings of the quarks. With the entry of neutrino oscillations into the field, the issue of lepton masses has added a new dimension to the problem. In the literature one finds many models of quark and lepton mass matrices. However, the mass and mixing problems remain unsolved.
In order to identify the importance of different areas for nitrogen retention in the Lagoon of Venice, Italy, undisturbed sediment cores of different origin were collected in late April 1998. The cores were transferred to the laboratory and incubated for denitrification activity using the method of 'nitrogen isotope pairing'. The sampled sediments were collected in a freshwater stream (Stn A)I an
Social differences in the role of habits in health-related behaviour are explored within both sociology and economics, where we define habits as non-reflective, repetitive behaviour. The corresponding theoretical perspectives are the habitus theory, the theory of individualization, and habits as rational decision rules. Sixteen thematically structured interviews are analysed using qualitative meth
This paper presents a new constraint-driven method for fast identification of computational patterns that is a part of DURASE system (Generic Environment for Design and Utilization of Reconfigurable Application-Specific Processors Extensions). The patterns identified by our system form a base for application specific instruction selection and processor extension generation. Our method ide
In post-World War II agricultural research, a new perspective on "peasant society" developed. This approach is still vigorous today and implies that peasant society defined by subsistence production, the safety-first principle, and a stable village system with moral obligations-leads to conservative behavior toward change. It also assumes that only external forces can tear down the system and forc
Stimulation around the superior cerebellar peduncle or within the deep cerebellar nuclei is known to inhibit the inferior olive with a very long latency. It has been suggested that this inhibition is mediated by the GABA-ergic nucleo-olivary pathway, but alternative explanations such as activation of an indirect excitatory pathway or a pathway via the red nucleus are possible. A long-latency inhib
We reviewed the literature on urothelial carcinoma in the prostatic urethra and prostate. We concluded that the incidence of urothelial carcinoma in the prostatic urethra and prostate is probably underestimated. This fact warrants thorough follow-up of patients with high-risk bladder cancers and also whole-mount examination of the prostate after cystectomy to recognize the true incidence and exten
Popular Abstract in Swedish Det finns ett starkt samband mellan kronisk inflammation och cancer. Ett av de mer etablerade sambanden är den mellan kronisk inflammation i tarmen och den i Sverige tredje vanligaste cancersjukdomen, nämligen tjocktarmscancer. Risken för tjocktarmscancer korrelerar med inflammationsutbredning, varaktighet och svårighetsgrad. Den inflammatoriska processen regleras av reCysteinyl leukotrienes (LTC4, LTD4 and LTE4) are potent pro-inflammatory lipids derived from arachidonic acid and mediate their effect through CysLT1R and CysLT2R. There is a strong correlation between long-standing inflammatory bowel disease where these pro-inflammatory mediators are abundant and colorectal cancer. We have shown that LTD4 via its receptor CysLT1 induces expression of proteins ass
Physicians caring for the critically ill are now expected to acquire competence in echocardiography. It has become an indispensable diagnostic and monitoring tool in acute care settings where it is generally accepted to have therapeutic impact. There are a number of indications for a critical care echocardiographic study, and the most important queries include those pertaining left and right ventr
We compared eelgrass Zostera marina communities in 3 regions in Sweden believed to be affected by eutrophication and overfishing, to determine whether bottom-up or top-down processes control the biomass of epiphytic macroalgae and grazers. Nitrogen and carbon isotope signatures were analyzed to explore the food webs and to identify the grazing species feeding on filamentous algae and/or eelgrass.
Although diabetes is one of the most serious global health problems, there is no real cure yet for it. The conventional insulin treatment programs aimed at life quality improvement do not take into account the psychological aspects of the disease. Because diabetes has important psychological components, it seems reasonable to consider hypnosis as an adjunct therapy for diabetes. This paper examine
This article develops two arguments. First, at a national level in Bulgaria, the human trafficking framework is inoperable for identifying abuses worthy of consideration. By comparing the Bulgarian criminal law definition of human trafficking with the international law definition, I argue that the national criminal law definition is overly inclusive. This state of the Bulgarian criminal law makes
Many children with adverse reactions to beta-lactams are labelled as allergic without performing an allergy study to confirm it. In this retrospective study of 10 years, we have detected only 3.3% positive cases. Although International Guidelines recommend a second allergy work-up in patients with a negative study, we found from our results a low profitability of retesting.
In recent times, the imminent lack of public IPv4 addresses has attracted the attention of both research community and industry. The cellular industry has decided to combat this problem by using IPv6 for all new terminals. However, the success of 3G network deployment will depend on the services offered to end users. Currently, almost all services reside in the public IPv4 address space, making th
Objective. The aim of this study was to determine the prevalence of moderate ischemic mitral regurgitation (IMR) in the contemporary CABG population. We also aimed to correlate the effective regurgitant orifice area (ERO) of any regurgitant mitral valve in patients with coronary artery disease with the semiquantitative integrated scale of IMR. Design. From March 15 through June 15, 2006, 510 conse
