Student engagement, truancy, and cynicism : a longitudinal study from primary school to upper secondary education
2021
Truancy in upper secondary education is a widespread problem, which contributes significantly to school dropout risk. However, the underlying mechanisms of truancy have remained unstudied. This longitudinal study of 1853 Finnish students examined how initial levels and changes in student engagement from primary (Grade 6) to lower secondary school (Grades 7 and 9) predicted truancy in upper secondary education, and whether cynicism (losing interest in school) mediated the relationship between engagement and truancy. Growth curve models showed that high engagement levels in primary school and increases in engagement over time predicted less truancy in upper secondary education. Cynicism media…
Incorporación de elementos traza en conchas de melanopsis durante el crecimiento : posibilidades de aplicación en paleoecología
1988
El objetivo del presente trabajo está encaminado al estudio de las variaciones de oligoelementos en la concha de un gasterópodo de agua dulce del género Melanopsis (U dufouri (FERUSSAC), con dos morfotipos) y si éstas tienen que ver, o no, con la fluctuación de una serie de parámetros ambientales. La importancia del trabajo radica en la posibilidad de la aplicación paleoecológica de sus resultados, ya que el género MelanopsÍs tiene un abundante registro fósil durante todo el Cenozoico. La incorporación de oligoelementos se efectúa a medida que la concha va creciendo por acreción; lo ideal sería que tal crecimiento fuera circadiano, ya que se podría seguir día a día, sobre la concha, la fluc…
Selaimen sormenjälkitunnistamisen torjunta käyttöjärjestelmäavusteisella virtualisoinnilla
2017
Selaimen sormenjälkitunnistaminen mahdollistaa käyttäjien seurannan käyttäjien yksityisyyttä luokkaavasti. Tutkielmassa selvitetään voidaanko käyttöjärjestelmäavusteisilla virtualisointiteknologioilla vastata selaimen sormenjälkitunnistamisen torjunnan asettamiin haasteisiin. Tutkielmassa havaittiin neljä eri haastetta selaimen sormenjälkitunnistamisen torjunnalle. Tutkielma keskittyy Linux-kernelin tukemiin käyttöjärjestelmäavusteisiin virtualisointiteknologiohin, jotka mahdollistavat ohjelmistokonttien toteuttamisen.

A black-box, general purpose quadratic self-consistent field code with and without Cholesky Decomposition of the two-electron integrals
2021
We present the implementation of a quadratically convergent self-consistent field (QCSCF) algorithm based on an adaptive trust-radius optimisation scheme for restricted open-shell Hartree���Fock (ROHF), restricted Hartree���Fock (RHF), and unrestricted Hartree���Fock (UHF) references. The algorithm can exploit Cholesky decomposition (CD) of the two-electron integrals to allow calculations on larger systems. The most important feature of the QCSCF code lies in its black-box nature ��� probably the most important quality desired by a generic user. As shown for pilot applications, it does not require one to tune the self-consistent field (SCF) parameters (damping, Pulay's DIIS, and other simil…
Review article: recommended reading list of early publications on atomic layer deposition - outcome of the "virtual Project on the History of ALD"
2017
Atomic layer deposition (ALD), a gas-phase thin film deposition technique based on repeated, self-terminating gas-solid reactions, has become the method of choice in semiconductor manufacturing and many other technological areas for depositing thin conformal inorganic material layers for various applications. ALD has been discovered and developed independently, at least twice, under different names: atomic layer epitaxy (ALE) and molecular layering. ALE, dating back to 1974 in Finland, has been commonly known as the origin of ALD, while work done since the 1960s in the Soviet Union under the name "molecular layering" (and sometimes other names) has remained much less known. The virtual proj…
Zagadnienia teologiczne sakramentu namaszczenia chorych
2016
Z bogatego zakresu problematyki teologicznej nowej liturgii obrzędów sakramentu namaszczenia chorych, zwłaszcza zawartej we wprowadzeniu teologiczno-pastoralnym, w czytaniach biblijnych i tekstach euchologijnych, autor szerzej omawia jedynie zagadnienia podstawowe. Należą do nich: wymiar chrystologiczny i paschalny sakramentu namaszczenia chorych; umacniająca rola Ducha Świętego w życiu chorego; wymiar eklezjalny tego sakramentu. W sposób skrótowy zasygnalizowano jeszcze takie zagadnienia teologiczno-pastoralne, jak: wymiar pokutny sakramentu namaszczenia; sens choroby w ujęciu teologicznym; potrzeba wprowadzenia nadzwyczajnego szafarza (np. diakona stałego); problem udzielania tego sakrame…
MutSa expression predicts a lower disease-free survival in malignant salivary gland tumors:an immunohistochemical study
2021
Appropriate DNA replication is vital to maintain cell integrity at the genomic level. Malfunction on DNA repair mechanisms can have implications related to tumor behavior. Our aim was to evaluate the expression of key complexes of the DNA mismatch-repair system MutS? (hMSH2-hMSH6) and MutS? (hMSH2-hMSH3) in a panel comprising the most common benign and malignant salivary gland tumors (SGT), and to determine their association with disease-free survival. Ten cases of normal salivary gland (NSG) and 92 of SGT (54 benign and 38 malignant) were retrieved. Immunohistochemistry was performed for hMSH2, hMSH3, hMSH6. Scanned slides were digitally analyzed based on the percentage of positive cells w…
Development of New Targeted Inulin Complex Nanoaggregates for siRNA Delivery in Antitumor Therapy.
2021
Here, a novel strategy of formulating efficient polymeric carriers based on the already described INU-IMI-DETA for gene material whose structural, functional, and biological properties can be modulated and improved was successfully investigated. In particular, two novel derivatives of INU-IMI-DETA graft copolymer were synthesized by chemical functionalisation with epidermal growth factor (EGF) or polyethylenglycol (PEG), named INU-IMI-DETA-EGF and INU-IMI-DETA-PEG, respectively, in order to improve the performance of already described “inulin complex nanoaggregates” (ICONs). The latter were thus prepared by appropriately mixing the two copolymers, by varying each component from 0 to 100 wt%…
Inulin Derivatives Obtained Via Enhanced Microwave Synthesis for Nucleic Acid Based Drug Delivery
2015
A new class of therapeutic agents with a high potential for the treatment of different socially relevant human diseases is represented by Nucleic Acid Based Drugs (NABD), including small interfering RNAs (siRNA), decoy oligodeoxynucleotides (decoy ODN) and antisense oligonucleotides (ASOs). Although NABD can be engineered to be specifically directed against virtually any target, their susceptibility to nuclease degradation and the difficulty of delivery into target tissues severely limit their use in clinical practice and require the development of an appropriate nanostructured delivery system. For delivery of NABD, Inulin (Inu), a natural, water soluble and biocompatible polysaccharide, wa…
"Postfit yields Y(4S)" of "Search for $B^{+}\to K^{+}\nu\bar{\nu}$ decays using an inclusive tagging method at Belle II"
2022
Yields in on-resonance data and as predicted by the simultaneous fit to the on- and off-resonance data, corresponding to an integrated luminosity of 63 and 9 fb$^{−1}$, respectively. The predicted yields are shown individually for charged and neutral B-meson decays and the five continuum background categories. The leftmost three bins belong to the first control region (CR1) with BDT$_{2} \in [0.93; 0.95]$ and the other nine bins correspond to the signal region (SR), three for each range of BDT$_{2} \in [0.95; 0.97; 0.99; 1.0]$. Each set of three bins is defined by $p_{T}(K^{+}) \in [0.5; 2.0; 2.4; 3.5] \rm{GeV}/c^{2}$.
