Veselīga dzīvesveida pārvaldības lietotne

2022

Kvalifikācijas darbā ir izstrādāta veselīga dzīvesveida pārvaldības sistēma tīmeklī, tā kā viņa ir veidota ar React palīdzību, ir iespējams lietot konkrēto lietotni pārlūkprogrammā. Līdz šim skatoties uz lielāko daļu sporta lietotņu ir saskatāma viena kopēja īpašība tā ir vienkāršības un vienotības trūkums. Ir ļoti daudz visvisādu programmu, kuras veic funkcijas līdzīgas kā darbā izstrādātā lietotne, bet lielākā daļa no tām veic tikai vienu funkciju, proti, dod iespēju veidot treniņu kompleksus, vai skaitīt uzkrātās kalorijas, kas padara procesu grūtāku, jo ir jālēkā no lietotnes uz lietotni, ir programmas, kuras piedāvā abus variantus, bet tie ir slēgti aiz samaksas sliekšņa. Konkrētā darb…

Darba rezultāts ir funkcionālajām prasībām atbilstoša, intuitīva sistēma, kuru izmanto vairākās mācību ies…

Influence of Viscosity on Mass Transfer Performance of Unbaffled Stirred Vessels

2013

Unbaffled stirred tanks are seldom employed in the process industry as they are considered poorer mixers than baffled vessels. However they may be expected to provide significant advantages in a wide range of applications (e.g. crystallization, food and pharmaceutical processes, etc) where the presence of baffles is often undesirable. Moreover, in plants or animal cell cultivation bioreactors, where cell damage is often caused by bursting bubbles at the air –medium interface (Barret et al., 2010), they can provide sufficient mass transfer through the free surface vortex, so bubble formation and subsequent bursting inside the reactor can be conveniently avoided (Scargiali et al., 2012). In t…

Multimetallic Oxynitrides Nanoparticles for a New Generation of Photocatalysts

2019

A versatile synthetic strategy for the preparation of multimetallic oxynitrides has been designed and here exemplarily discussed considering the preparation of nanoscaled zinc-gallium oxynitrides and zinc-gallium-indium oxynitrides, two important photocatalysts of new generation, which proved to be active in key energy related processes from pollutant decomposition to overall water splitting. The synthesis presented here allows the preparation of small nanoparticles (less than 20 nm in average diameter), well-defined in size and shape, yet highly crystalline and with the highest surface area reported so far (up to 80 m2  g-1 ). X-ray diffraction studies show that the final material is not a…

Could PD-1/PDL1 immune checkpoints be linked to HLA signature?

2019

The outstanding clinical expansion of monoclonal antibodies (mAbs) to programmed cell death receptor-1 (PD-1) (nivolumab and pembrolizumab) and PD-1 ligand-1 (PDL-1) (atezolizumab, avelumab and durvalumab) has received an increasing level of interest regarding immunotherapy and multidrug combinations, for the treatment of a number of common human malignancies. Some patients treated with these agents receive remarkable benefits in term of quality of life, progression-free (PFS) and overall survival (OS). However, a significant percentage of these patients experience immune-related adverse events (irAEs), while others present with an ultra-rapid disease progression, defined as hyperprogressio…

Predator-Induced Plasticity on Warning Signal and Larval Life-History Traits of the Aposematic Wood Tiger Moth, Arctia plantaginis

2021

Correction Frontiers in Ecology and Evolution Volume 9 Article Number 737651 DOI 10.3389/fevo.2021.737651 Published JUL 29 2021 Predator-induced plasticity in life-history and antipredator traits during the larval period has been extensively studied in organisms with complex life-histories. However, it is unclear whether different levels of predation could induce warning signals in aposematic organisms. Here, we investigated whether predator-simulated handling affects warning coloration and life-history traits in the aposematic wood tiger moth larva, Arctia plantaginis. As juveniles, a larger orange patch on an otherwise black body signifies a more efficient warning signal against predators…

Vegetation Patterns in the Hyperbolic Klausmeier Model with Secondary Seed Dispersal

2023

This work focuses on the dynamics of vegetation stripes in sloped semi-arid environments in the presence of secondary seed dispersal and inertial effects. To this aim, a hyperbolic generalization of the Klausmeier model that encloses the advective downhill transport of plant biomass is taken into account. Analytical investigations were performed to deduce the wave and Turing instability loci at which oscillatory and stationary vegetation patterns arise, respectively. Additional information on the possibility of predicting a null-migrating behavior was extracted with suitable approximations of the dispersion relation. Numerical simulations were also carried out to corroborate theoretical pre…

Human Papillomavirus Type 16 E7 Peptide-Directed CD8+ T Cells from Patients with Cervical Cancer Are Cross-Reactive with the Coronavirus NS2 Protein

2003

ABSTRACTHuman papillomavirus type 16 (HPV16) E6 and E7 oncoproteins are required for cellular transformation and represent candidate targets for HPV-specific and major histocompatibility complex class I-restricted CD8+-T-cell responses in patients with cervical cancer. Recent evidence suggests that cross-reactivity represents the inherent nature of the T-cell repertoire. We identified HLA-A2 binding HPV16 E7 variant peptides from human, bacterial, or viral origin which are able to drive CD8+-T-cell responses directed against wild-type HPV16 E7 amino acid 11 to 19/20 (E711-19/20) epitope YMLDLQPET(T) in vitro. CD8+T cells reacting to the HLA-A2-presented peptide from HPV16 E711-19(20)recogni…

A single tube PCR assay for detecting viruses and their recombinants that cause tomato yellow leaf curl disease in Mediterranean basin

2007

Tomato yellow leaf curl disease (TYLCD) is well known in Mediterranean countries, where it has been causing severe losses in tomato crops for decades. Until recently, two viruses (with several isolates) in the genus Begomovirus, family Geminiviridae, have been associated with the epidemics: Tomato yellow leaf curl virus (TYLCV) and Tomato yellow leaf curl Sardinia virus (TYLCSV). However, recombinants between these, such as Tomato yellow leaf curl Malaga virus (TYLCMalV), are spreading, and new methods for detecting all viruses present in the region are needed. By considering all DNA sequences available of viruses causing TYLCD in the Mediterranean basin, a PCR/RFLP protocol was developed t…
