Darba tēma: „Sociālo prasmju veidošana 18 – 21 gadīgiem jauniešiem ar vidēji smagiem un smagiem garīgās attīstības traucējumiem ārpusstundu darbā”. Darba autors: Envija Brūdere Darba zinātniskais vadītājs: Dr. paed. Rasma Vīgante Atslēgas vārdi: jaunieši ar vidēji smagiem un smagiem garīgās attīstības traucējumiem, socializācija, sociālās prasmes, ārpusstundu darbs. Pētījuma hipotēze: sociālās prasmes jauniešiem ar vidēji smagiem un smagiem garīgās attīstības traucējumiem veidosies sekmīgāk, ja: •tiks ievērotas šo jauniešu individuālās attīstības īpatnības, intereses un līdzšinējā sociālā pieredze; •tiks sniegts pedagoģiskais atbalsts un organizētas daudzveidīgas aktivitātes ārpusstundu dar…

Spēka-izturības rādītāju dinamika ielu vingrošanā ārpusstundu nodarbībās

2015

Darba teorētiskā daļa balstīta uz pedagoģijas, psiholoģijas, sporta literatūras analīzi. Darbā tiek izmantoti pedagogu, psihologu un sporta speciālistu ieteikumi par sporta treniņu, fiziskās sagatavotības un spēka-izturības biomotorās spējas attīstīšanu. Darba praktiskajā daļā veikts pedagoģiskais pētījums, izstrādāts treniņu nodarbību tematiskais plāns diviem mēnešiem, veikts datu salīdzinājums pētījuma sākumā un noslēgumā, kas ļauj secināt, ka skolotājam-trenerim, strādājot pēc plāna, kur tiek ievērota noteikta vingrinājumu secība un nedēļas nodarbībās augstas intensitātes slodzes mijās ar vidējas un zemas intensitātes slodzēm, skolēniem ievērojami uzlabojas spēka-izturības rādītāji.

Epidemiology, aetiology and treatment of skin and soft tissue infections: final report of a prospective multicentre national registry

2022

Skin and soft tissue infections (SSTIs) represent a heterogenous group of pathological conditions involving the skin or the underlying subcutaneous tissues, fascia and muscle, characterised by a considerable variety of clinical presentations, severity and possible aetiological pathogens. Although previous analyses on restricted types of SSTIs and population have already been published, we conducted a large nationwide surveillance program on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients and their managem…

The Crosstalk Between Signaling Pathways and Cancer Metabolism in Colorectal Cancer.

2021

Colorectal cancer (CRC) is one of the most frequently diagnosed cancers worldwide. Metabolic reprogramming represents an important cancer hallmark in CRC. Reprogramming core metabolic pathways in cancer cells, such as glycolysis, glutaminolysis, oxidative phosphorylation, and lipid metabolism, is essential to increase energy production and biosynthesis of precursors required to support tumor initiation and progression. Accumulating evidence demonstrates that activation of oncogenes and loss of tumor suppressor genes regulate metabolic reprogramming through the downstream signaling pathways. Protein kinases, such as AKT and c-MYC, are the integral components that facilitate the crosstalk bet…

Confined crystallization of a HKUST-1 metal–organic framework within mesostructured silica with enhanced structural resistance towards water

2017

A HKUST-1 metal–organic framework was crystallized in the NH2-modified mesostructured silica FDU-12 in order to improve its structural stability upon water exposure. In-depth structural characterization studies of the designed composite confirmed successful formation of the MOF phase within the ordered spherical mesopores of the silica matrix. In spite of the confinement within the cavities, MOF exhibits full accessibility for the adsorbed gas molecules. In contrast to the bulk HKUST-1, which undergoes slow phase transition in a humid environment, the structural integrity of the HKUST-1 in the humid-protective matrix remains unchanged even after immersion and stirring in water at elevated t…

High-Spin → Low-Spin Relaxation in [Fe(bpp)2](CF3SO3)2 H2O after LIESST and Thermal Spin-State Trapping—Dynamics of Spin Transition Versus Dynamics o…

1996

The iron(II) complex [Fe(bpp)2]-(CF3SO3)2 H2O (bpp = 2,6-bis(pyrazolyl-3-yl)pyridine) shows a thermal spin transition associated with a hysteresis of approximately 140 K width. The transition temperatures T1/2 (where the fraction of HS species γHS = 0.5) are 147 K and ≈285 K in the cooling and heating directions, respectively. The compound shows the LIESST and reverse-LIESST effects at low temperatures. The relaxation of the metastable HS states generated by LIESST was observed quantitatively at temperatures between 77.5 and 85 K by Mossbauer spectroscopy. Metastable HS states can also be generated by rapid cooling of the sample. The relaxation of the metastable HS states formed by thermal …

Cooperative phenomena and light-induced bistability in iron(II) spin-crossover compounds

1999

In iron(II) spin-crossover compounds, the transition from the 1A1 low-spin state at low temperatures to the 5T2 high-spin state at elevated temperatures is accompanied by a large increase in metal-ligand bond lengths. The resulting elastic interactions may be pictured as an internal pressure which is proportional to the concentration of the low-spin species. Because pressure stabilises the low-spin state relative to the high-spin state this results in a positive feedback. Thermal transition curves in neat iron(II) spin-crossover compounds are thus invariable much steeper than in diluted mixed crystals, and the high-spin→low-spin relaxation following the light-induced population of the high-…

Effect of quantized conductivity on the anomalous photon emission radiated from atomic-size point contacts

2019

We observe anomalous visible to near-infrared electromagnetic radiation emitted from electrically driven atomic-size point contacts. We show that the number of photons released strongly depends on the quantized conductance steps of the contact. Counter-intuitively, the light intensity features an exponential decay dependence with the injected electrical power. We propose an analytical model for the light emission considering an out-of-equilibrium electron distribution. We treat photon emission as bremsstrahlung process resulting from hot electrons colliding with the metal boundary and a find qualitative accord with the experimental data.
