Kaijonharjun bulevardi:Linnanmaan tÀydennysrakentaminen
TiivistelmÀ. KandidaatintyönÀni suunnittelin yleissuunnitelman Oulun linnanmaalle ja piirsin sen pohjalta asemakaavan alueelle. Työ oli osa yhdyskuntasuunnittelun, asuntosuunnittelun ja rakennusopin yhteisprojektia. Yleissuunnitelman pohjalta suunniteltiin yhdelle tontille kerrostalo asuntosuunnittelun kurssilla ja siihen edelleen tarkemmat piirustukset rakennusopin kurssilla.
Pohjana työlle oli alakylÀntien bulevardisointi, jossa tavoitteena on liittÀÀ Linnanmaa tiiviimmin Oulun keskustaan. Yleissuunnitelmaa laatiessani minulla oli kolme pÀÀtavoitetta: ympÀröivien alueiden liittÀminen luontevasti bulevardiin ja sen joukkoliikenneyhteyksiin, alueen yleinen jÀsentÀminen ja kulun selkeyttÀminen sekÀ alueelle ominaisen metsÀisyyden sÀilyttÀminen.
Bulevardin varrelle sijoitin kaikkein tiiveimmÀn rakentamisen, estÀmÀÀn melun kantautumisen ympÀröiville asuinalueille. ItÀ-LÀnsiakselille suunnittelin kÀvelykatu ja puistokÀytÀvÀn, jota voidaan hyödyntÀÀ myös hulevesien kÀsittelyyn. Samalla se kokoaa liikenteen ympÀröiviltÀ alueilta bulevardille ja on tÀten luonteva paikka esimerkiksi kahvilatoiminnalle. Korkeammat maamerkkirakennukset sijoitin nÀkymÀakselien pÀÀtepisteisiin, jolloin ne auttavat alueella orientoitumiseen sekÀ viestivÀt suuren yliopistokampuksen lÀheisyydestÀ.
MetsÀisyyden pyrin sÀilyttÀmÀÀn suurkorttelin keskelle jÀÀvÀllÀ suurehkolla metsÀalueella, sekÀ syyninmaan pohjoispuolitse kulkevalla puustokÀytÀvÀllÀ. Virkakadun ympÀristön pysÀköintivoittoista aluetta jÀsentelin pienimittakaavaisella, Puu-LinnanmaatyyppisellÀ korttelirakenteella. LisÀksi Liikuntahallin ympÀristöön sijoitin lisÀÀ urheilutoimintoja. PysÀköinnin jÀrjestin keskitetysti muutamaan pysÀköintilaitokseen, minkÀ ansiosta asuinalueet oli mahdollista rauhoittaa liialliselta autoliikenteeltÀ. Pidin kuitenkin huolen, ettÀ kaikki tontit ovat myös esimerkiksi huolto, ja pelastusliikenteen sekÀ liikuntaesteisten saavutettavissa.
Asuntosuunnittelun vaiheessa jatkoin tavoitettani Puu-Linnanmaan ympÀristön pienimittakaavaisesta tÀydentÀmisestÀ. Kerrostalosuunnitelmani keskiössÀ olivat laadukkaat yhteistilat sekÀ niiden saavutettavuus. Onnistuin myös luomaan mielestÀni viihtyisiÀ korttelipihoja tontille. Rakennusopin vaiheessa pyrin suunnittelemaan toteutuspiirustukset niin, ettÀ puuarkkitehtuurin henki ja rakennuksen intiimi olemus eivÀt katoaisi.
Kaiken kaikkiaan onnistuin mielestÀni luomaan alueelle miellyttÀvÀÀ asuinympÀristöÀ ja viihtyisiÀ kaupunkitiloja sekÀ opiskelijoiden, ettÀ muidenkin tarpeisiin

Shell-like structures in our cosmic neighbourhood
Signatures of the processes in the early Universe are imprinted in the cosmic
web. Some of them may define shell-like structures characterised by typical
scales. We search for shell-like structures in the distribution of nearby rich
clusters of galaxies drawn from the SDSS DR8. We calculate the distance
distributions between rich clusters of galaxies, and groups and clusters of
various richness, look for the maxima in the distance distributions, and select
candidates of shell-like structures. We analyse the space distribution of
groups and clusters forming shell walls. We find six possible candidates of
shell-like structures, in which galaxy clusters have maxima in the distance
distribution to other galaxy groups and clusters at the distance of about 120
Mpc/h. The rich galaxy cluster A1795, the central cluster of the Bootes
supercluster, has the highest maximum in the distance distribution of other
groups and clusters around them at the distance of about 120 Mpc/h among our
rich cluster sample, and another maximum at the distance of about 240 Mpc/h.
The structures of galaxy systems causing the maxima at 120 Mpc/h form an almost
complete shell of galaxy groups, clusters and superclusters. The richest
systems in the nearby universe, the Sloan Great Wall, the Corona Borealis
supercluster and the Ursa Major supercluster are among them. The probability
that we obtain maxima like this from random distributions is lower than 0.001.
Our results confirm that shell-like structures can be found in the distribution
of nearby galaxies and their systems. The radii of the possible shells are
larger than expected for a BAO shell (approximately 109 Mpc/h versus
approximately 120 Mpc/h), and they are determined by very rich galaxy clusters
and superclusters with high density contrast while BAO shells are barely seen
in the galaxy distribution. We discuss possible consequences of these
differences.Comment: Comments: 9 pages, 10 figures, Astronomy and Astrophysics, in pres
Low-level liquid scintillation spectrometer for Ă-counting
A new liquid scintillation (LS) spectrometer has been developed. lt improves the signal to noise ratio of C-14 assays by an order of magnitude compared to conventional LS systems. As a result, precision for a modern sample is 0.2 % and the dating limit is 64 Ky BP for a 15 ml sample of benzene. Sophisticated MCA facilities allow the use of Multiparameter Multichannel Analysis for data validation and age evaluation. Despite the high sophistication, the spectrometer, (named QUANTULUS) is seif contained, microprocessor controlled and user friendly. lt can be used with full advantage in a normal laboratory environment
The Presence of Visual Neglect after Thrombolytic Treatment in Patients with Right Hemisphere Stroke
Visual neglect (VN) is a common consequence of right hemisphere (RH) stroke. The aims of this study were to explore the presence of VN after RH stroke in the patients with (T+) or without (Tâ) thrombolytic treatment, and to determine whether thrombolysis is a predictor of VN. The study group consisted of 77âRH infarct patients. VN was evaluated with six conventional subtests of the Behavioural Inattention Test (BIT). Stroke severity was assessed using the National Institute of Health Stroke Scale (NIHSS). In the neuropsychological examination, 22% of all RH stroke patients had VN. VN was present in 15% of the patients in the T+ group and in 28% of the patients in the Tâ group, but the difference was not statistically significant. Despite that, patients in the Tâ group had a higher risk of VN than patients in the T+ group. Our results suggest that thrombolysis independently predicted absence of VN

Positive effects of methylphenidate on hyperactivity are moderated by monoaminergic gene variants in children with autism spectrum disorders.
Methylphenidate (MPH) reduces hyperactive-impulsive symptoms common in children with autism spectrum disorders (ASDs), however, response and tolerability varies widely. We hypothesized monoaminergic gene variants may moderate MPH effects in ASD, as in typically developing children with attention-deficit/hyperactivity disorder. Genotype data were available for 64 children with ASD and hyperactivity who were exposed to MPH during a 1-week safety/tolerability lead-in phase and 58 who went on to be randomized to placebo and three doses of MPH during a 4-week blinded, crossover study. Outcome measures included the Clinical Global Impression-Improvement (CGI-I) scale and the Aberrant Behavior Checklist (ABC-hyperactivity index). A total of 14 subjects discontinued the study because of MPH side effects. Subjects were genotyped for variants in DRD1-DRD5, ADRA2A, SLC6A3, SLC6A4, MAOA and MAOB, and COMT. Forty-nine percent of the sample met positive responder criteria. In this modest but relatively homogeneous sample, significant differences by DRD1 (P=0.006), ADRA2A (P<0.02), COMT (P<0.04), DRD3 (P<0.05), DRD4 (P<0.05), SLC6A3 (P<0.05) and SLC6A4 (P<0.05) genotypes were found for responders versus non-responders. Variants in DRD2 (P<0.001) and DRD3 (P<0.04) were associated with tolerability in the 14 subjects who discontinued the trial. For this first MPH pharmacogenetic study in children with ASD, multiple monoaminergic gene variants may help explain individual differences in MPH's efficacy and tolerability
