Binocular visual function after staged implantation of extended-depth-of-focus intraocular lens targeting emmetropia and -0.5 diopter: A prospective comparison
The prospective comparative case series aimed to evaluate the binocular uncorrected visual acuities (BUCVAs) after staged implantations of extended-depth-of-focus intraocular lenses (EDOF IOLs) targeting emmetropia and -0.5 diopter (D). Diffractive EDOF IOLs with an add power of +1.75 D were implanted in the first eyes targeting emmetropia or -0.5 D according to the patients' preferences, then the targets for the second eyes were determined 1 week or longer after the implantation. IOL powers were determined with the SRK/T formula. Consequently, the subjects were divided into 3 groups: those with emmetropia targeted bilaterally (group EE, 22 patients), those with -0.5 D targeted bilaterally (group MM, 21 patients), and those with monovision of emmetropia and -0.5 D (group EM, 21 patients). Manifest refraction spherical equivalent (MRSE), BUCVA from 0.3 to 5 meters, spectacle use, and questionnaire regarding photic symptoms and patient satisfaction were assessed 3 months postoperatively. No significant differences were seen in the mean BUCVAs at any distance (P > 0.23), spectacle use (P = 0.13), or photic symptoms and patient satisfaction (P>0.65). When the EE and MM groups were assigned based on the MRSE, the EE group was better at 5 m (P = 0.005) while the MM group at 0.5 m (P = 0.031). The effect of different targeted refractions was not identified due to insufficient accuracy in the use of the SRK/T power calculation
Taloyhtiön pihasaneeraus : Esimerkkikohteena As Oy Kananlaulu
Työn taustana käytettiin lähiöiden suurimman aikakauden, 1960- ja 1970-lukujen kerrostalojen
ajankohtaista peruskorjaustarvetta. Peruskorjaustarve koskee niin kiinteistön piha-aluetta kuin kiinteistön
muitakin osia. Pihojen suurin korjaustarve perustuu kuluneiden kalusteiden, varusteiden,
kasvillisuuden ja muiden osien huonokuntoisuuteen. Lisäksi muuttuneet turvallisuusvaatimukset
sekä esteettömyyden haasteet tuovat lisätarvetta pihojen saneerauksille.
Työni tavoitteena oli lisätä viihtyisyyttä ja parantaa Asunto Oy Kananlaulun piha-aluetta sen saneerauksella.
Saneerauksessa huomioidaan metsälähiön tyypilliset pihasuunnittelun erityispiirteet.
Piha-alueen analyysin avulla arvioitiin sen nykytilaa paikan päällä kohteessa. Samalla tutustuttiin
myös suunnitelma- ja urakka-asiakirjoihin.
Työn pohjana tutkittiin kerrostalorakentamisen ja niiden piha-aluerakentamisen kehitystä Suomessa.
Tietopohjaksi haettiin tietoa myös kerrostalopihojen kunnostuksesta ja kunnostusprosessista.
Tuloksena oli kirjallinen selostus piharakentamisen vaiheista. Työni toimeksiantajana oli VRJ
Pohjois-Suomi Oy.
Työn tulokset ovat hyödynnettävissä kerrostalopihojen peruskorjaushankkeissa. Asunto Oy Kananlaulun
piha-analyysi ja pihasaneeraus voidaan liittää osaksi Kaukovainion kehittämistä. Työn tulokset
antavat myös minulle itselleni mahdollisuuden kehittää omaa osaamistani viherrakentamisen
työnjohdossa.As a background for the work was used the topical need of renovation in the block of flats in the
suburbs built in the 1960- and 1970´s. The renovation need applies both to the yard and the other
parts of the property. The biggest need of renovation is based on the poor condition of the worn
out equipment, vegetation and other parts of the yard. Furthermore the changed requirements of
safety and accessibility increase the renovation need.
The goal on my work was to add the comfort and attractiveness of the yard of Asunto Oy Kananlaulu.
During the renovation the typical characteristics of a wooden suburb were taken into account.
The present situation of the yard was estimated on site. At the same time I familiarized myself the
documents of planning and subcontracting.
For the background of the work the development of the building of the block of flats and their yards
was investigated. Also the renovation of yards and the process of renovation was studied. The
result of the work is a written report of the stages of the yard construction. The principal of the work
was VRJ Pohjois-Suomi Oy.
The results of the work can be utilized in high-rise yards’ renovation projects. The analyses and
renovation of the yard can be linked to the development of Kaukovainio area. The results of the
work gave me the possibility to develop my own skills on supervision of work at green construction
Multi-modality imaging for interventions in tricuspid valve disease
Several studies have demonstrated that severe tricuspid regurgitation (TR) has a significant negative impact on morbidity and mortality. Nowadays, several therapeutic options to treat TR are available and patients at high surgical risk can also be treated with transcatheter procedures. For the management of patients with TR, an accurate assessment of the tricuspid valve and its surrounding structures is therefore of crucial importance and has gained significant interest in the medical community. Different imaging modalities can provide detailed information on the tricuspid valve apparatus, right ventricle, right atrium, and coronary circulation which are fundamental to define the timing and anatomic suitability of surgical and percutaneous procedures. The present review illustrates the role of 2D and 3D echocardiography, cardiac magnetic resonance, and multidetector row computed tomography for the assessment of the tricuspid valve and right heart with a particular focus on the data needed for planning and guiding interventional procedures.Cardiolog
Large mass dileptons from the passage of jets through quark gluon plasma
We calculate the emission of large mass dileptons originating from the
annihilation of quark jets passing through quark gluon plasma. Considering
central collisions of heavy nuclei at SPS, RHIC and LHC energies, we find that
the yield due to the jet-plasma interaction gets progressively larger as the
collision energy increases. We find it to be negligible at SPS energies, of the
order of the Drell-Yan contribution and much larger than the normal thermal
yield at RHIC energies and up to a factor of ten larger than the Drell-Yan
contribution at LHC energies. An observation of this new dilepton source would
confirm the occurrence of jet-plasma interactions and of conditions suitable
for jet-quenching to take place.Comment: 9 pages, 11 figures; references added, improved calculation,
