Sapropeļa izmantošana personīgās higiēnas līdzekļos: sapropeļa cieto ziepju īpašības un izmantošanas dzīves cikla novērtējums

2015

Bakalaura darba “Sapropeļa izmantošana personīgas higiēnas līdzekļos: sapropeļa cieto ziepju īpašības un izmantošanas dzīves cikla novērtējums” ietvaros tika noteikti triju tirgū pieejamo un četru paštaisīto ezeru nogulumu cieto ziepju kvalitātes rādītāji un īpašības, paštaisītām ziepēm tika modelēts izmantošanas dzīves cikls. Paštaisītās sapropeļa ziepes tika pagatavotas, izmantojot sapropeli kā pildījumu. Darba teorētiskajā daļā tika veikta zinātniskās literatūras analīze par cieto ziepju pagatavošanas metodēm, piedevu īpašībām un to sastāvu, produkta izmantošanas dzīves ciklu, kā arī par sapropeļa izmantošanu kosmetoloģijā un balneoloģijā. Bakalaura darba ietvaros pēc autores izstrādātās…

Suppression ofBotrytis cinereacausing the grey mould disease of grape-vine by an aggressive mycoparasite,Pythium radiosum

1999

Pythium radiosum Paul has been found to be an aggressive mycoparasite of Botrytis cinerea which causes grey mould disease on the grape-vine. The mycoparasitic fungus enters the host mycelium, coagulates its protoplasm, empties its contents and finally comes out producing numerous ramifications and sexual structures. When the infected mycelium of B. cinerea is applied to the leaves of the grape-vine, the characteristic grey mould symptoms fail to appear. Since P. radiosum causes no harm to the grape-vine, it can be used as a biological control agent against B. cinerea. A brief account of the mycoparasite and its antagonism towards B. cinerea is discussed here.

An assessment method for the quantification of Daktulosphaira vitifoliae (Fitch) (Hem., Phylloxeridae) populations in the field

2003

:  Grape phylloxera is a plant parasite that has started to become a pest again in European viticulture in spite of the use of grafted rootstocks. Since the middle of the 1980s, there have been various reports of vine damage caused by phylloxera. It was shown that in some cases there is no direct correlation between the occurrence of phylloxera and vine damage. In this context, phytopathogenic microorganisms, especially fungi, are mentioned in literature. To investigate the possible interactions it is necessary to be able to assess phylloxera populations in the field, e.g. to correlate phylloxera abundance with the vigour of the vines. Because of the non-homogenous distribution of the grape…

The Efficacy of Antigen Processing Is Critical for Protection against Cytomegalovirus Disease in the Presence of Viral Immune Evasion Proteins▿

2009

ABSTRACT Cytomegaloviruses (CMVs) code for immunoevasins, glycoproteins that are specifically dedicated to interfere with the presentation of antigenic peptides to CD8 T cells. Nonetheless, the biological outcome is not an immune evasion of the virus, since CD8 T cells can control CMV infection even when immunoevasins are expressed. Here, we compare the processing of a protective and a nonprotective epitope derived from the same viral protein, the antiapoptotic protein M45 in the murine model. The data provide evidence to conclude that protection against CMVs critically depends on antigenic peptides generated in an amount sufficient to exhaust the inhibitory capacity of immunoevasins.

Activity investigation of pinostrobin towards herpes simplex virus-1 as determined by atomic force microscopy

2009

In the present study, the antiviral activity of pinostrobin towards herpes simplex virus-1 (HSV-1) was investigated by MTT assay and atomic force microscopy. Pinostrobin can inhibit HSV-1 replication with 50% effective concentration (EC(50)) of 22.71 ± 1.72 μg/ml. MTT assay showed HSV-1 was significantly inhibited when pretreated with pinostrobin, with the inhibition of 85.69 ± 2.59%. Significant changes in morphology and size of HSV-1 were observed by atomic force microscopy (AFM) in response to pinostrobin treatment. AFM topography and phase images showed that with increasing time, the envelope was shedded and damaged, finally leading to virus inactivation. With increasing concentration, …

EDGE: explorer of diffuse emission and gamma-ray burst explosions

2009

How structures on various scales formed and evolved from the early Universe up to present time is a fundamental question of astrophysical cosmology. EDGE will trace the cosmic history of the baryons from the early generations of massive star by Gamma-Ray Burst (GRB) explosions, through the period of cluster formation, down to very low redshifts, when between a third and one half of the baryons are expected to reside in cosmic filaments undergoing gravitational collapse by dark matter (Warm Hot Intragalactic Medium: WHIM). In addition EDGE, with its unprecedented observational capabilities, will provide key results on several other topics. The science is feasible with a medium class mission …

Anne d’Autriche en ses images : légitimation du pouvoir féminin et culture visuelle de la majesté dans la France du XVIIe siècle

2018

Anne of Austria offers an important part, yet neglected, in the the development of royal iconography in seventeenth century France. Devoided from management of power under the reign of her husband Louis XIII, she is however the subject of many representations. The number of her images increases when she accedes to the responsibilities of the government at the death of the king, in 1643, becoming regent in the name of her minor son, Louis XIV. Beyond its majority in 1651, she maintains herself at a prominent place, until the death of Mazarin in 1661. During these two decades, a deep political crisis in France culminates in the so-called Fronde. In this context, the image of Anne of Austria b…

Tests of atomic charge-exchange cells for collinear laser spectroscopy

2012

Abstract The performance characteristics of two charge-exchange cells (CECs) with horizontal and vertical cell configurations were determined by neutralizing a 10-keV rubidium ion beam in a potassium vapor. The neutralization efficiency and the fluorescence line shape of the 5s 2 S 1 / 2 ↔ 5 p 2P3/2 (D2) transition in neutral 85Rb were investigated as a function of the reservoir temperature used to control the potassium vapor density. The CECs exhibited similar neutralization performance and at neutralization efficiencies greater than 25–50% an asymmetric line shape of the rubidium D2 fluorescent signal was observed. The asymmetry was attributed to inelastic channels in the charge-exchange …

Genesis of fumarolic emissions as inferred by isotope mass balances: CO 2 and water at Vulcano Island, Italy

2002

We have developed a quantitative model of CO2 and H2O isotopic mixing between magmatic and hydrothermal gases for the fumarolic emissions of the La Fossa crater (Vulcano Island, Italy). On the basis of isotope balance equations, the model takes into account the isotope equilibrium between H2O and CO2 and extends the recent model of chemical and energy two-end-member mixing by Nuccio et al. (1999). As a result, the H2O and CO2 content and the δD, δ18O, and δ13C isotope compositions for both magmatic and hydrothermal end-members have been assessed. Low contributions of meteoric steam, added at a shallow depth, have been also recognized and quantified in the fumaroles throughout the period fro…
