Diversity of Isomerization Patterns and Protolytic Forms in Aminocarbene PdII and PtII Complexes Formed upon Addition of N,N′-Diphenylguanidine to Me…
2017
Reaction of the palladium(II) and platinum(II) isocyanide complexes cis-[MCl2(CNR)2] [M = Pd, R = C6H3(2,6-Me2) (Xyl), 2-Cl-6-MeC6H3, cyclohexyl (Cy), t-Bu, C(Me)2CH2(Me)3 (1,1,3,3-tetramethylbuth-1-yl abbreviated as tmbu); M = Pt, R = Xyl, 2-Cl-6-MeC6H3, Cy, t-Bu, and tmbu] with N,N′-diphenylguanidine (DPG) leads to DPG-derived metal-bound deprotonated acyclic diaminocarbene (ADC) species. This reaction occurs via a two-step process, involving the initial coupling of the guanidine with one of the isocyanides and leading to deprotonated monocarbene monochelated species, while the next addition grants the deprotonated bis-carbene bis-chelated metal compounds. DPG behaves as nucleophile, depr…
Smart prototype selection for machine learning based on ignorance zones analysis
2018
The size of databases has been considerably growing over recent decades and Machine Learning algorithms are not ready to process such large volume of information. Being one of the most useful algorithms in Data Mining the Nearest neighbor classifier suffers from high storage requirements and slow response when working with large data sets. Prototype Selection methods help to alleviate this problem by choosing a subset of data with a smaller size. In this thesis, the overview of existing instance selection methods is provided together with the introduction of a new approach. The majority of current methods select a subset experimentally by checking whether certain point affects classificatio…
High-affinity and selective detection of pyrophosphate in water by a resorcinarene salt receptor
2017
N-Alkyl ammonium resorcinarenes selectively bind pyrophosphate in pure water with an exceptionally high binding constant of up to 1.60 × 107 M–1, three orders of magnitude higher than ATP.
Pārrobežu laulības šķiršanas lietu piekritība
2017
Bakalaura darbā “Pārrobežu laulības šķiršanas lietu piekritība” ir izpētīti aktuālie problēmjautājumi Eiropas Savienības ietvaros, kas saistīti ar pārrobežu laulības šķiršanas lietu piekritības noteikšanu un kurus regulē Briseles II bis regula. Kā dažus no aktuālākajiem problēmjautājumiem varētu minēt, pirmkārt, nevienprātību jēdziena “pastāvīgā dzīvesvieta” interpretācijā Briseles II bis regulas piemērotāju vidū, otrkārt, grūtības piekritības noteikšanā gadījumos, kad abiem laulātajiem ir dubultā pilsonība un, treškārt, “forum shopping” iespējamību. Izpētot pārrobežu laulību šķiršanas lietu problemātiku, autore piedāvā vadlīnijas laulāto pastāvīgās dzīvesvietas noteikšanai, kā arī secina, …

Spatial variation in the evolutionary potential and constraints of basal metabolic rate and body mass in a wild bird
2023
An organism's energy budget is strongly related to resource consumption, performance, and fitness. Hence, understanding the evolution of key energetic traits, such as basal metabolic rate (BMR), in natural populations is central for understanding life-history evolution and ecological processes. Here we used quantitative genetic analyses to study evolutionary potential of BMR in two insular populations of the house sparrow (Passer domesticus). We obtained measurements of BMR and body mass (Mb) from 911 house sparrows on the islands of Leka and Vega along the coast of Norway. These two populations were the source populations for translocations to create an additional third, admixed ‘common ga…
Evolutionary trade-offs in a small mammal : a quantitative genetics approach
2017
Limited resources force individuals to trade-off between life-history traits. A vast diversity of life-history strategies, which optimally combine life history traits, can be found. Knowledge of the genetic basis of this phenotypic variation is key to understanding evolutionary processes. I approached life-history evolution by estimating quantitative genetic parameters for a set of life-history traits in the bank vole (Myodes glareolus). The work is based on a laboratory-kept colony subjected to two-way selection for litter size (High- (H) and Low- (L) lines). Costs of the created reproductive strategies were observed in natural conditions. Selection increased the difference in litter size …
Genetics of condition and sexual selection
2007
FM Tarmo Ketolan ekologian ja ympäristönhoidon väitöskirjan ”Genetics of Condition and Sexual Selection” (Kunnon ja seksuaalivalinnan genetiikka) tarkastustilaisuus Jyväskylän yliopistossa. Vastaväittäjänä professori Juha Merilä (Helsingin yliopisto) ja kustoksena dosentti Janne Kotiaho.Linkki väitöksen pdf-versioon tiedotteen lopussa.FM Tarmo Ketola havaitsi väitöstutkimuksessaan, että geneettisesti huonolaatuiset sirkkayksilöt pystyvät käyttämään vähemmän energiaa aktiviteetteihin kuin hyvälaatuiset. Koska sisäsiitos lisäsi perusenergiankulutusta eli ruumiintoimintojen ylläpitoon kulutettua energiaa, se heikensi yksilöiden kuntoa.– Aiemmin on oletettu, että huonolaatuisilla yksilöillä on …
Rac1-Regulated Endothelial Radiation Response Stimulates Extravasation and Metastasis That Can Be Blocked by HMG-CoA Reductase Inhibitors
2011
Radiotherapy (RT) plays a key role in cancer treatment. Although the benefit of ionizing radiation (IR) is well established, some findings raise the possibility that irradiation of the primary tumor not only triggers a killing response but also increases the metastatic potential of surviving tumor cells. Here we addressed the question of whether irradiation of normal cells outside of the primary tumor augments metastasis by stimulating the extravasation of circulating tumor cells. We show that IR exposure of human endothelial cells (EC), tumor cells (TC) or both increases TC-EC adhesion in vitro. IR-stimulated TC-EC adhesion was blocked by the HMG-CoA reductase inhibitor lovastatin. Glycyrr…
Stan zachowania gatunków drzew rosnących na rekultywowanych powierzchniach wyrobisk śląskich zakładów przemysłu wapienniczego "Opolwap" S.A
2004
Województwo opolskie charakteryzuje się występowaniem dużych pokładów skał węglanowych. Służą one jako surowiec dla przemysłu cementowo-wapienniczego. Eksploatacja wapieni wiąże się z ogromnymi przekształceniami geomechanicznymi powierzchni ziemi. Jednym z podstawowych problemów wynikających z działalności przemysłu wapienniczego jest rekultywacja terenów przekształconych. W latach 2000-2001 prowadzone były badania dotyczące stanu zachowania upraw leśnych występujących na rekultywowanych powierzchniach Śląskich Zakładów Przemysłu Wapienniczego "Opolwap" S.A w Tarnowie Opolskim. Zakres prac obejmował wykonanie inwentaryzacji drzew oraz określenie ich kondycji zdrowotnej. Powierzchnie badawcz…
