Occupation probabilities of single particle levels using the microscopic interacting boson model: Application to some nuclei of interest in neutrinol…
2016
We have developed a new method to calculate the occupancies of single particle levels in atomic nuclei. This method has been developed in the context of the microscopic interacting boson model, in which neutron and proton degrees of freedom are treated explicitly. The energies of the single particle levels constitute a very important input for the calculation of the occupancies in this method. In principle these energies can be considered as input parameters that can be fitted to reproduce the experimental occupancies. Instead of fitting, in this study we have extracted the single particle energies from experimental data on nuclei with a particle more or one particle less than a shell closu…
Raspberry Pi mikrodatora izmantošana automašīnu numuru atpazīšanai un plūsmas reģistrēšanai
2017
Lai automatizētu – noprogrammētu – kādu procesu, darbinātu to, izmantojot mākoņtehnoloģijas, parasti ir nepieciešams dators – kvadrātiskas formas lieta, ko varētu izmantot programmēšanai un ko nevar nopirkt par viena pārtikas veikala apmeklējuma čeka summu, ātri ielikt kabatā un aiznest uz mājām. Tāpēc problēmjautājums ir, kā uzprogrammēt un darbināt kādu risinājumu maksimāli lēti, izmantojot kādu mobilu, mazu iekārtu, piemēram, mikrodatoru? Maģistra darba mērķis un rezultāts ir uzprogrammēts un attālināti darbināms, lēts un mobils risinājums, kas izmanto kredītkartes lieluma mikrodatoru Raspberry Pi, kameras moduli un programmēšanas valodu Python, veic slēgtā teritorijā iebraucošu automašī…
Materials for depollution based on the model of manganese dioxygenase
2013
La utilización intensiva de pesticidas ha traído consigo la presencia de una gran cantidad de moléculas contaminantes en aguas y suelos. Los tratamientos para degradar estas moléculas son caros, por lo que es de gran interés la búsqueda de soluciones más baratas. En el caso de los catecoles, existen enzimas, las catecol-dioxigenasas, que abren el ciclo aromático por oxidación con dioxígeno. Las condiciones suaves y la gran disponibilidad de este oxidante podrían ofrecer una solución para esos problemas de polución. El objetivo de este trabajo de tesis es mimetizar un tipo particular de dioxigenasa, la dioxigenasa de manganeso. Dado que tanto la primera esfera de coordinación como la segunda…

A multifaceted field sampling approach for the management of extremely narrow endemic vascular plant species
2022
Extremely narrow endemic plant species (ENEs) are generally connected with micro- refugia characterized by particular environmental conditions. In-depth knowledge of the ecological requirements of ENEs is fundamental to plan appropriate conservation measures. Using cross-cutting technology, this paper gives a multifaceted approach to collect on-site data on the ecology of ENEs, defines the protocols for a correct sampling design and describes the type of equipment, the time and expenditure needed. Our sampling approach is based on two orthogonal transects, long enough to extrapolate the whole ecological gradient across the area of occupancy of the target species. Microclimatic data are reco…
Cyano-Phycocyanin: Mechanisms of Action on Human Skin and Future Perspectives in Medicine
2022
Cyano-phycocyanin is one of the active pigments of the blue-green algae and is usually isolated from the filamentous cyanobacteria Arthrospira platensis Gomont (Spirulina). Due to its multiple physiological functions and non-toxicity, cyano-phycocyanin may be a potential substance for the topical treatment of various skin diseases. Considering that the conventional medicine faces drug resistance, insufficient efficacy and side effects, the plant origin compounds can act as an alternative option. Thus, the aim of this paper was to review the wound healing, antimicrobial, antioxidative, anti-inflammatory, antimelanogenic and anticancer properties and mechanisms of cyano-phycocyanin topical ac…
Skin Immunomodulation during Regeneration: Emerging New Targets
2021
Adipose-Derived Stem Cells (ADSC) are present within the hypodermis and are also expected to play a pivotal role in wound healing, immunomodulation, and rejuvenation activities. They orchestrate, through their exosome, the mechanisms associated to cell differentiation, proliferation, and cell migration by upregulating genes implicated in different functions including skin barrier, immunomodulation, cell proliferation, and epidermal regeneration. ADSCs directly interact with their microenvironment and specifically the immune cells, including macrophages and T and B cells, resulting in differential inflammatory and anti-inflammatory mechanisms impacting, in return, ADSCs microenvironment and …
Hopes and Limits of Adipose-Derived Stem Cells (ADSCs) and Mesenchymal Stem Cells (MSCs) in Wound Healing
2020
Adipose tissue derived stem cells (ADSCs) are mesenchymal stem cells identified within subcutaneous tissue at the base of the hair follicle (dermal papilla cells), in the dermal sheets (dermal sheet cells), in interfollicular dermis, and in the hypodermis tissue. These cells are expected to play a major role in regulating skin regeneration and aging-associated morphologic disgraces and structural deficits. ADSCs are known to proliferate and differentiate into skin cells to repair damaged or dead cells, but also act by an autocrine and paracrine pathway to activate cell regeneration and the healing process. During wound healing, ADSCs have a great ability in migration to be recruited rapidly…
Microneedle-Based Delivery: An Overview of Current Applications and Trends
2020
Microneedle arrays (MNA) are considered as one of the most promising resources to achieve systemic effects by transdermal delivery of drugs. They are designed as a minimally invasive, painless system which can bypass the stratum corneum, overcoming the potential drawbacks of subcutaneous injections and other transdermal delivery systems such as chemical enhancers, nano and microparticles, or physical treatments. As a trendy field in pharmaceutical and biomedical research, its applications are constantly evolving, even though they are based on very well-established techniques. The number of molecules administered by MNA are also increasing, with insulin and vaccines administration being the …
