Four lichen species new to Spain

2003

Se presentan cuatro nuevas citas de líquenes de España, concretamente Aspicilia ruceniuro, Lecanora stenotropa, Vezdaea leprosa y Xanthoparmelia plitii. Las especies probablemente no son raras pero habían sido obviadas, bien por ser inconspicuas bien por ser similares morfológicamente a otras especies. Four species of Lichens are reported as new to Spain, namely Aspicilia moenium, Lecanora stenotropa, Vezdaea leprosa aud Xanthoparmelia plitii. The species are probably not rare, but overlooked, since they are either inconspicuous or morphologically similar to other species. Eva.Barreno@uv.es

New Records of Sceliotrachelinae (Hymenoptera: Platygastridae) in Iran

2020

The hymenopteran family Platygastridae is a large group of parasitic wasps. A survey was carried out on the subfamily Sceliotrachelinae (Hym.: Platygastridae) in East Azerbaijan and Fars provinces of Iran. The genus Fidobia Ashmead and three species, Allotropa conventus Maneval, Fidiobia hofferi Kozlov and Isolia mongolica (Kozlov) are newly recorded from Iran. Illustrations of the morphological characteristics and their geographical distribution are presented.

Un problema di critica testuale nel 'Versus Sancte Marie' limosino (BnF lat. 1139, c. 49r-50r)

2017

I quattro componimenti interamente o parzialmente in volgare occitanico (limosino settentrionale) contenuti all’interno della parte più antica (sec. XI ex.) del cosiddetto ‘tropario’ di San Marziale di Limoges (Parigi, BnF, lat. 1139) sono stati studiati soprattutto per la loro rilevanza linguistica e culturale. Questo contributo si focalizza sul testo, relativamente poco studiato, del 'Versus Sancte Marie' (incipit "O Maria, Deu maire"), nel quale persiste un errore finora non notato e sanabile ricorrendo al principio ecdotico di «contesto remoto» (Au. Roncaglia).

Search for Gamma-Ray Emission from the Sun during Solar Minimum with the ARGO-YBJ Experiment

2019

The hadronic interaction of cosmic rays with solar atmosphere can produce high energy gamma-rays. The gamma-ray luminosity is correlated both with the flux of primary cosmic rays and the intensity of the solar magnetic field. The gamma-rays below 200 GeV have been observed by Fermi without any evident energy cutoff. The bright gamma-ray flux above 100 GeV has been detected only during solar minimum. The only available data in the TeV range come from the HAWC observations, however, outside the solar minimum. The ARGO-YBJ data set has been used to search for sub-TeV/TeV gamma-rays from the Sun during the solar minimum from 2008 to 2010, the same time period covered by the Fermi data. A suitab…

Synthetic Haptens and Monoclonal Antibodies to the Cyanotoxin Anatoxin‐a

2019

Early warning systems for monitoring toxic events may benefit from the availability of monoclonal antibodies enabling the sensitive and specific detection of anatoxin-a, a cyanotoxin involved in numerous cases of animal poisoning resulting from toxic algal blooms in freshwaters. Through the synthesis of three functionalized derivatives of anatoxin-a, we have succeeded in generating the first-ever reported immunoreagents (bioconjugates and antibodies) suitable for the development of immunoanalytical approaches aimed at rapid and onsite detection of this harmful cyanotoxin.

Synthesis and pharmacology of 6-substituted benztropines: discovery of novel dopamine uptake inhibitors possessing low binding affinity to the dopami…

2005

A series of 6alpha- and 6beta-substituted benztropines were synthesized. A marked enantioselectivity was observed for the 6beta-methoxylated benztropines, the (1R)-isomers being more potent than the corresponding (1S) compounds. The racemic 6alpha-methoxy-3-(4',4' '-difluorodiphenylmethoxy)tropane (5 g) was the most potent compound. It has been found that modifications at the 6-position of benztropine might reduce the DAT binding affinity, maintaining otherwise a significant dopamine uptake inhibitory activity. A reinvestigation of the absolute configuration of 6beta-methoxytropinone proved the 6R configuration for the (+)-enantiomer.

Synthesis and monoamine uptake inhibition of conformationally constrained 2β-carbomethoxy-3β-phenyl tropanes

2009

A series of 2beta-carbomethoxy-3beta-phenyl tropanes with conformationally constrained nitrogen substituents were synthesized as potential selective dopamine transporter ligands. These novel compounds were examined for their monoamine uptake inhibition potency at the human dopamine transporter (hDAT), the human serotonin transporter (hSERT) and the human noradrenalin transporter (hNET), stably expressed in human embryonic kidney cells (HEK). A SAR-study was conducted to determine the contribution of extended, 4-fluorinated, conformationally constrained C4 chains at the tropane nitrogen to human monoamine transporter affinity and selectivity.

The experimental facility for the Search for Hidden Particles at the CERN SPS

2019

The Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS accelerator with its 400 $\mathrm{\small GeV/c}$ proton beam offers a unique opportunity to explore the Hidden Sector. The proposed experiment is an intensity frontier experiment which is capable of searching for hidden particles through both visible decays and through scattering signatures from recoil of electrons or nuclei. The high-intensity experimental facility developed by the SHiP collaboration is based on a number of key features and developments which provide the possibility of probing a large part of the parameter space for a wide range of models with light long-lived superweakly interacting particles…
