Språkbadselevers skriftliga kunskaper i svensk grammatik enligt utvecklingsnivåerna av processbarhetsteorin
2016
Tutkielman tarkoituksena oli tarkastella kuudesluokkalaisten kielikylpyoppilaiden ruotsin kieliopin taitoja Manfred Pienemannin prosessoitavuusteorian valossa. Tärkein tutkimuskysymys oli, mille teorian viidestä tasosta oppilaat sijoittuvat. Tutkimuksen materiaalina oli 12 19 oppilaan kirjoittamaa kirjoitelmaa, eli osa kirjoitelmista oli kirjoitettu ryhmässä. Tutkimus oli kvalitatiivinen ja menetelmänä käytettiin teorialähtöistä sisällönanalyysiä. Tulokset osoittivat, että oppilaat sijoittuivat prosessoitavuusteorian neljännelle ja viidennelle tasolle. Parityöskentelystä johtuen tuloksia voidaan tarkastella ennemmin ryhmä- kuin yksilötasolla. Pienestä aineistosta johtuen tuloksia ei myöskää…
Przepis art. 299 Kodeksu spółek handlowych jako funkcja prawa o niewypłacalności
2022
Przepis art. 299 Kodeksu spółek handlowych nawiązuje do treści art. 298 Kodeksu handlowego. Polski ustawodawca model spółki z ograniczoną odpowiedzialnością generalnie oparł na regulacji niemieckiej. Niemniej z uwagi na częste przypadki nadużywania formy spółki kapitałowej wprowadził szczególną odpowiedzialność członków zarządu. Regulacja art. 299 Kodeksu spółek handlowych przez lata była przedmiotem ożywionej debaty nauko-wej i wielu orzeczeń sądowych. W niniejszym opracowaniu stawiana jest teza, że wskazana regulacja jest funkcją prawa upadłościowego. Konsekwencją tej tezy jest wskazanie na zakres odpowiedzialności członka zarządu spółki z ograniczoną odpowiedzialnością, który podej-mie o…

This article refers to criminal liability for performing aesthetic medicine treatment in a form of plastic surgery without patient’s consent, substitute consent (including collective) or substitute consent of Family Court. Article presents the current state of law in this respect and the correlation between applicable regulations of various branches of law and lex generalis regulations that deal with this issue, i.e. aesthetic medicine treatment.The author evaluates and describes the legal issues related with aesthetic medicine, including the patient’s consent, extended disclosure obligation as well as the ground for statutory liability for committing a prohibited act that is described and …
Electronic shell structures in bare and protected metal nanoclusters
2016
This short review discusses the concept of the electronic shell structure in the context of metal nanoclusters. Electronic shell structure is a natural consequence of quantization of fermionic states in a quantum confinement, where the symmetry of the confining potential creates energetically close-lying sets of states that reflect the symmetry of the potential. It was introduced in cluster physics in early 1980s and initially influenced greatly by the related model of nuclear shell structure from 1950’s. Three application areas are discussed consisting of free gas phase clusters, clusters supported by insulating oxides or oxide thin films, and clusters that are synthesized by wet chemistry…
Influencing the self‐sorting behavior of [2.2]paracyclophane based ligands by introducing isostructural binding motifs
2020
Two isostructural ligands with either nitrile ( L nit ) or isonitrile ( L iso ) moieties directly connected to a [2.2]paracyclophane backbone with pseudo‐meta substitution pattern have been synthesized. The ligand itself ( L nit ) or its precursors ( L iso ) were resolved via HPLC on a chiral stationary phase and the absolute configuration of the isolated enantiomers was assigned by XRD analysis and/or by comparison of quantum‐chemical simulated and experimental ECD‐spectra. Surprisingly, the resulting metallosupramolecular aggregates formed in solution upon coordination of [(dppp)Pd(OTf) 2 ] differ in their composition: whereas L nit forms dinuclear complexes L iso exclusively forms trinuc…
[Ag67(SPhMe2)32(PPh3)8]3+: Synthesis, Total Structure, and Optical Properties of a Large Box-Shaped Silver Nanocluster
2016
Engineering the surface ligands of metal nanoparticles is critical in designing unique arrangements of metal atoms. Here, we report the synthesis and total structure determination of a large box-shaped Ag67 nanocluster (NC) protected by a mixed shell of thiolate (2,4-dimethylbenzenethiolate, SPhMe2) and phosphine (triphenylphosphine, PPh3) ligands. Single crystal X-ray diffraction (SCXRD) and electrospray ionization mass spectrometry (ESI-MS) revealed the cluster formula to be [Ag67(SPhMe2)32(PPh3)8]3+. The crystal structure shows an Ag23 metal core covered by a layer of Ag44S32P8 arranged in the shape of a box. The Ag23 core was formed through an unprecedented centered cuboctahedron, i.e.,…
Bulky Surface Ligands Promote Surface Reactivities of [Ag141X12(S-Adm)40]3+ (X=Cl, Br, I) Nanoclusters: Models for Multiple-Twinned Nanoparticles
2017
Surface ligands play important roles in controlling the size and shape of metal nanoparticles and their surface properties. In this work, we demonstrate that the use of bulky thiolate ligands, along with halides, as the surface capping agent promotes the formation of plasmonic multiple-twinned Ag nanoparticles with high surface reactivities. The title nanocluster [Ag141X12(S-Adm)40]3+ (where X = Cl, Br, I; S-Adm = 1-adamantanethiolate) has a multiple-shell structure with an Ag71 core protected by a shell of Ag70X12(S-Adm)40. The Ag71 core can be considered as 20 frequency-two Ag10 tetrahedra fused together with a dislocation that resembles multiple-twinning in nanoparticles. The nanocluster…
Hamstring Graft Preparation for ACL Reconstruction
2022
Anterior cruciate ligament (ACL) reconstruction represents one of the most common procedures in orthopedic surgery. It usually involves the harvest of both gracilis and semitendinosus tendons from the ipsilateral knee. Different methods of hamstring graft preparation have been proposed in recent years, to create an adequate graft diameter reducing morbidity linked to gracilis tendon harvesting procedure. More recently, the use of only 1 of the tendons (semitendinosus) in a tripled or quadrupled arrangement has been described, especially in an all-inside type of reconstruction. Having a thicker tendon with a quadrupled semitendinosus (ST), instead of double gracilis and ST enables to have a …
Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety
2019
σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…
