On arithmetic sums of Ahlfors-regular sets
2021
Let $A,B \subset \mathbb{R}$ be closed Ahlfors-regular sets with dimensions $\dim_{\mathrm{H}} A =: \alpha$ and $\dim_{\mathrm{H}} B =: \beta$. I prove that $$\dim_{\mathrm{H}} [A + \theta B] \geq \alpha + \beta \cdot \tfrac{1 - \alpha}{2 - \alpha}$$ for all $\theta \in \mathbb{R} \, \setminus \, E$, where $\dim_{\mathrm{H}} E = 0$.

Biomechanical comparison between sprint start, sled-pulling and selected squat type exercises
2012
The purpose of the present study was to compare kinetics, kinematics and muscle activity between sprint start, sled-pulling and selected squat type exercises and also to examine how different exercises and variables correlate with the performance time of the block start (10 m). Nine male athletes (4 sprinters, 3 decathlonists, 1 long jumper and 1 triple jumper; mean ± SD; age = 24.9 ± 3.9 yr; height = 180.4 ± 5.9 cm; weight = 80.3 ± 7.5 kg; 100 m record = 11.35 ± 0.29 s) performed measurements and different force-time, electromyographic (EMG) and kinematic variables were compared to sprint start. Most of the comparison was done to the block phase (the phase of force production towards start…
Uniportal bilateral video-assisted sequential thoracoscopic extended thymectomy
2017
Standard video-assisted thoracoscopic surgery has been reported as a minimally invasive approach alternative to sternotomy for management of myasthenia gravis (MG) associated with thymoma or thymic hyperplasia. Uniportal video-thoracoscopy is an evolution of standard multi-portal video-thoracoscopy for management of several thoracic diseases but its role for resecting mediastinal tumor remains under-evaluated. Herein, we describe our experience with bilateral uniportal thoracoscopic sequential extended thymectomy with case and video illustrations.
Assembly and Translocation of Papillomavirus Capsid Proteins
2002
ABSTRACT The major and minor capsid proteins of polyomavirus are preassembled in the cytoplasm and translocated to the nucleus only as a VP1-VP2/VP3 complex. In this study, we describe independent nuclear translocation of the L1 major protein and the L2 minor capsid protein of human papillomavirus type 33 by several approaches. First, we observed that expression and nuclear translocation of L2 in natural lesions precede expression of L1. Second, using a cell culture system for coexpression, we found that accumulation of L2 in nuclear domain 10 (ND10) subnuclear structures precedes L1 by several hours. In contrast, complexes of L2 and mutants of L1 forced to assemble in the cytoplasm are tra…
Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems
2007
The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …
The Effect of Electrolytic Solution Composition on the Structure, Corrosion, and Wear Resistance of PEO Coatings on AZ31 Magnesium Alloy
2020
Plasma electrolytic oxidation coatings were prepared in aluminate, phosphate, and silicate-based electrolytic solutions using a soft-sparking regime in a multi-frequency stepped process to compare the structure, corrosion, and wear characteristics of the obtained coatings on AZ31 magnesium alloy. The XRD results indicated that all coatings consist of MgO and MgF2, while specific products such as Mg2SiO4, MgSiO3, Mg2P2O7, and MgAl2O4 were also present in specimens based on the selected solution. Surface morphology of the obtained coatings was strongly affected by the electrolyte composition. Aluminate-containing coating showed volcano-like, nodular particles and craters distributed over the …
Pašvaldību skolu funkcionālo areālu optimizācijas iespējas Zemgales plānošanas reģionā
2015
Maģistra darbā „Pašvaldību skolu funkcionālo areālu optimizācijas iespējas Zemgales plānošanas reģionā” analizēti pašvaldību pārvaldībā esošo vispārizglītojošo pamatskolu un vidusskolu funkcionālie areāli Zemgales plānošanas reģiona teritorijā. Skolu funkcionālie areāli raksturo izglītības iestāžu tīklu un norāda gan uz esošajām problēmām, gan optimizācijas iespējām. Maģistra darba mērķis ir sagatavot rekomendācijas skolu funkcionālo areālu optimizācijas iespējām Zemgales plānošanas reģionā. Rezultāti norāda uz būtiskām funkcionālo areālu atšķirībām reģiona austrumos un rietumos, kas nosaka atšķirīgas optimizācijas iespējas. Atslēgas vārdi: izglītība, funkcionālais areāls, reorganizācija, s…
Ainavas aspekti Zemgales līdzenuma pašvaldību plānošanas dokumentos
2019
Darba mērķis ir izvērtēt ainavas aspektus Zemgales līdzenuma pašvaldību telpiskās attīstības plānošanas dokumentos. Izmantojot kvalitatīvo kontentanalīzi, lai izprastu kādos kontekstos ainava tiek aplūkota novadu pašvaldību dokumentos – ilgtspējīgās attīstības stratēģija, attīstības un teritoriju plānojumos. Apkopot kādas ainavas vērtības ir atspoguļotas Zemgales līdzenuma teritoriju pašvaldību novadu dokumentos. Kā arī cik kvalitatīvi ievērojot, noteiktos reģionālos un nacionālos ainavu mērķus, savstarpēji ir pašvaldību plānošanas dokumenti.
