UL Botanical Garden Branch – Rhododendron Breeding and Experimental Nursery “Babite”

Established in 1980, July 1, the nursery covers 11.8 ha of pine forest near Riga, the village of Spilve, Babīte municipality. The founder of the nursery is Rihards Kondratovičs (1932–2017) academic, Dr. habil. biol. professor, breeder of rhododendrons, the head of the nursery until 2017. He studied the genus of rhododendrons for 60 years. This is the only specialised rhododendron nursery in Baltic states.

Measurement of Ds+ production and nuclear modification factor in Pb-Pb collisions at √sNN = 2.76 TeV

2016

The production of prompt D+ s mesons was measured for the first time in collisions of heavy nuclei with the ALICE detector at the LHC. The analysis was performed on a data sample of Pb-Pb collisions at a centre-of-mass energy per nucleon pair, √ sNN, of 2.76 TeV in two different centrality classes, namely 0–10% and 20–50%. D+ s mesons and their antiparticles were reconstructed at mid-rapidity from their hadronic decay channel D+ s → φπ+, with φ → K−K+, in the transverse momentum intervals 4 < pT < 12 GeV/c and 6 < pT < 12 GeV/c for the 0–10% and 20–50% centrality classes, respectively. The nuclear modification factor RAA was computed by comparing the pT-differential production yields in Pb-…

Functional reconstruction after subtotal glossectomy in the surgical treatment of an uncommon and aggressive neoplasm in this location: primary malig…

2014

Primary malignant melanoma of the oral cavity is a rare neoplasm, especially on the tongue. We report a case of mucosal melanoma at the base of the tongue, an extremely rare location (only about 30 cases have been reported in literature). The extension study doesn´t revealed distant metastatic lesions. The patient was treated by subtotal glossectomy and bilateral functional neck dissection. Tongue is one of the most difficult structures to reconstruct, because of their central role in phonation, swallowing and airway protection. The defect was reconstructed with anterolateral thigh free flap. Surgical treatment was supplemented with adjuvant immunotherapy. The post-operative period was unev…

Entropy of balance--some recent results.

2010

Abstract Background Entropy when applied to biological signals is expected to reflect the state of the biological system. However the physiological interpretation of the entropy is not always straightforward. When should high entropy be interpreted as a healthy sign, and when as marker of deteriorating health? We address this question for the particular case of human standing balance and the Center of Pressure data. Methods We have measured and analyzed balance data of 136 participants (young, n = 45; elderly, n = 91) comprising in all 1085 trials, and calculated the Sample Entropy (SampEn) for medio-lateral (M/L) and anterior-posterior (A/P) Center of Pressure (COP) together with the Hurst…

Master Degree in Migration Studies: Governance, Policies, and Cultures

MIGRANTS project intends to reinforce the institution capacity of Tunisia Higher Education System. Given its geo-political situation, Tunisia can play, in the specific context of Migrations, an important role for itself and for the surrounding countries, including, of course, the EU member states. In a coherent sense with Global Compact MIGRANTS project promotes a broad multi-stakeholder partnership to address higher education in Migration Studies in Tunisia in all its dimensions by including migrants, diasporas, local communities, civil society, academia, the private sector, parliamentarians, trade unions, national human rights institutions, the media and other relevant stakeholders in mig…

Coleoptera collection

A Coleoptera collection contains more than 20,000 specimens. Most of them are Curculionoidea, but also many others different families, from Europe, New Caledonia and Thailand. The Collection is partly digitalized as a part of BioMap project https://baza.biomap.pl/en/db. Most specimens are preserved as dry samples in vials or in alcohol.

Monte-Carlo Simulation of 3-Dimensional Glassy Polymer Melts: Reptation Versus Single Monomer Dynamics

1995

A polymer melt is simulated at finite temperature by the Monte-Carlo method. We use a coarse-grained model for the polymer system, the bond-fluctuation model. Static properties of the melt can be obtained by generating configurations not with single-monomer- dynamics which moves individual monomers locally, but reptation-dynamics which allows collec- tive motion of the chains. This algorithm can produce equilibrated configurations much faster. It is demonstrated that static properties do not differ from those obtained by single-monomer- dynamics. Values of the radius of gyration, the mean square bond length and similar quantities for different temperatures and densities are presented.

Sustainable chemistry as the key to innovation in resource-efficient science in the Anthropocene

The establishment of sustainable innovations and contributions to a circular economy represent the most important challenges for a future innovation-driven industrial society. Moreover, avoiding fossil carbon feedstock currently represents the most urgent issue within the Anthropocene. Here, sustainable chemical solutions open up a whole range of attractive options for challenges in raw material supply, energy conversion, chemical processes, and in materials science. The primary goal of this research initiative is the use of renewable raw materials, non-critical elements and the efficient use of renewable energies for the activation as well as conversion. To achieve this goal, the Faculties…

An Integrative Genomic and Proteomic Analysis of PIK3CA, PTEN, and AKT Mutations in Breast Cancer

2008

Abstract Phosphatidylinositol 3-kinase (PI3K)/AKT pathway aberrations are common in cancer. By applying mass spectroscopy–based sequencing and reverse-phase protein arrays to 547 human breast cancers and 41 cell lines, we determined the subtype specificity and signaling effects of PIK3CA, AKT, and PTEN mutations and the effects of PIK3CA mutations on responsiveness to PI3K inhibition in vitro and on outcome after adjuvant tamoxifen. PIK3CA mutations were more common in hormone receptor–positive (34.5%) and HER2-positive (22.7%) than in basal-like tumors (8.3%). AKT1 (1.4%) and PTEN (2.3%) mutations were restricted to hormone receptor–positive cancers. Unlike AKT1 mutations that were absent …
