What inner ear diseases cause benign paroxysmal positional vertigo?

Benign paroxysmal positional vertigo (BPPV) originating from the posterior semicircular canal (pSCC) is a common vestibular disorder that is easy to diagnose and usually easy to treat. The majority of patients with BPPV have no known inner ear disease; they have "primary" or "idiopathic" BPPV. However, a minority does have objective evidence of an inner ear disease on the same side as the BPPV and

Kafékultur, kommunikation och gränser

Popular Abstract in Swedish Kaféet är en mötesplats. Alla möten vilar på gränser - på gränser mellan de som möts, som umgänget frambringar. ”Kafékultur, kommunikation och gränser” är en studie av det sociala livet på kaféer, som utvecklar den socialpsykologiska innebörden av gränsen. Den kan ses som ett bidrag till förståelsen av vår tids informella och elementära sociala liv – intressant inte minThe café is a social meeting place. An as yet un-moulded aspect of social life is boundaries – how meetings rest on boundaries between participants that their intercourse brings forth. The aim of this dissertation is to study the café as a sociological and social–psychological phenomenon and at the same time contribute to forming the social–psychological aspect of boundaries. The study also contri

The lowest-lying doublet electronic states of CoC - A theoretical study

Multiconfigurational SCF and second-order perturbation theory have been employed to study seven low-lying electronic states of the CoC molecule (X-2 Sigma(+), A(2)Delta, B(2)Phi, C(2)Phi, D(2)Pi, E(2)Pi, and F(2)Sigma(+)). Three doublet electronic states have been described for the first time: B 2 (D C(2)Phi (R-0 = 1.617 angstrom, To = 10455 cm(-1). and a), = 1159 cm(-1)), and D(2)Pi (R-0 = 1.632

The influence of confining wall profile on quantum interference effects in etched Ga0.25In0.75As/InP billiards

We present measurements of the potential profile of etched GaInAs/InP billiards and show that their energy gradients are an order of magnitude steeper than those of surface-gated GaAs/AlGaAs billiards. Previously observed in GaAs/AlGaAs billiards, fractal conductance fluctuations are predicted to be critically sensitive to the billiard profile. Here we show that, despite the increase in energy gra

Investigation of the effect of different glassy carbon materials on the performance of Prussian blue based sensors for hydrogen peroxide

Three different kinds of glassy carbon (GC-R, GC-K, GC-G) were equally pretreated, further modified with electrochemically deposited Prussian Blue and used as sensors for hydrogen peroxide at an applied potential of -50 mV (vs. Ag|AgCl). Their performance was evaluated with respect to the following parameters: the coverage and electrochemistry of the electrodeposited Prussian Blue, the sensitivity

Effects of halothane on mucociliary activity in vivo

The effect of halothane on mucociliary activity in the rabbit maxillary sinus in vivo was recorded photoelectrically. Administration of halothane (1%, 2% or 4%) into the maxillary sinus induced a temporary acceleration of mucociliary activity. The peak increase (39.1% +/- 9.1%, p < 0.05, n = 5) was seen after the 4% concentration. Long-term exposure (60 minutes) of the maxillary sinus to halothane

Ta plats eller få plats? : Studier av marginaliserade människors förändrade vardagsliv

Syftet är att studera och analysera processer vars mål är att förändra vardagen för två marginaliserade grupper, så att de i större utsträckning blir delaktiga i samhället. De två undersökta grupperna är manliga unga narkomaner och äldre utvecklingsstörda. Avhandlingen består av tre geografiska perspektiv: 1) det tidsgeografiska synsättet, 2) känslan för platsen och 3) socialgeografiska teorier omThe aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. The thesis is permeated by three geographic perspectives: 1) the time-geographic approach, 2) sense of place and 3) social-geographic th

Tracing the Galactic Thick Disk to Solar Metallicities

We show that the Galactic thick disk reaches at least solar metallicities and that it experienced strong chemical enrichment during a period of ~3 Gyr, ending around 8-9 Gyr ago. This finding puts further constraints on the relation and interface between the thin and thick disks and their formation processes. Our results are based on a detailed elemental abundance analysis of 261 kinematically sel

Beyond Newtonian thinking – towards a non-linear archaeology : applying chaos theory to archaeology

In this article the authors suggest that chaos theory can provide us witha new perspective on archaeology. Newtonian thinking is predominantin archaeology, as well as in the humanities in general. This results inthe hegemony of analytic methods and a linear way of thinking on causeand effect. However, chaos theory has shown that behind many phen-omena that may seem random lies order. Since these c

Effects on the ciliated epithelium of protein D-producing and -nonproducing nontypeable Haemophilus influenzae in nasopharyngeal tissue cultures

A pair of isogenic, nontypeable Haemophilus influenzae strains, one expressing protein D and the other protein D-negative, was compared in their ability to cause damage in a human nasopharyngeal tissue culture model. Damage was assessed by measuring the ciliary beat frequency (CBF) of tissue specimens at 12 h intervals. Cultures inoculated with H. influenzae manifested a decrease in CBF beginning
