Andalusian hauberk identifiers. A new example
2019
El trabajo está dedicado a una nueva pequeña chapa circular de metal con inscripción incisa en árabe. Aporta la lectura y traducción de su texto y sitúa el objeto en un grupo especial dentro de la metalística medieval islámica. Es el quinto ejemplo que se conoce. Eran piezas que iban sujetas a cotas de malla del ejército cordobés con la función de identificarlas para reintegrarlas al arsenal después de que fueran usadas. Es de la época del califato de Hišām II. The article deals with a new small metal disk with an Arabic inscription incised on it. The study gives the reading and translation of its text and places the object in the Islamic medieval metalwork group it belongs to. It is the fi…
La conversión del complejo militar-industrial en Rusia en el proceso de transición económica.
1995
Dentro del actual proceso de reformas, los cambio en la industria militar han pasado ha un primer plano. Este rasgo confiere a la actual ola de reformas unas particularidades singulares. Durante la etapa soviética este sector industrial gozó de una serie de privilegios que le permitieron disponer de una lógica de funcionamiento propia. Por este motivo, la aplicación de reformas al complejo militar-industrial (CMI)', como a cualquier otro sector de la economía rusa, se ha transformado en un rasgo def~dor de la reforma rusa. La industria militar rusa se está reestructurando plenamente. No sólo se está operando una descentralización en la gestión, sino que los fenómenos de pnvatización se exti…
La nueva doctrina militar y la transformación en la industria de defensa rusa.
1996
La Unión Soviética, hasta 1991, ha jugado un papel de potencia mundial. La industria de defensa ha contribuido a sustentar esta posición político-militar. La desintegración de la URSS ha alterado sustancialmente las condiciones políticas internacionales y Rusia ha pretendido establecerse en la heredera directa de la Unión Soviética. Sin embargo, que Rusia adquiera el rango de potencia mundial dependerá del tamaño y estructura de su industria de defensa. Existe, pues, una relación directa entre la evolución de la industria de defensa y el papel que desempeñará Rusia en el contexto internacional. A finales de 1993 se aprobó la nueva doctrina militar que debería expresar los intereses nacional…
Rational enantioselective design of chiral heterobimetallic single-chain magnets: synthesis, crystal structures and magnetic properties of oxamato-br…
2011
A new series of neutral oxamato-bridged M(II)Cu(II) chiral chains of general formula [MCuL(x)(S)(m)(H(2)O)(n)]·aS·bH(2)O [L(1)=(M)-1,1'-binaphthalene-2,2'-bis(oxamate) with M=Mn (1a) and Co (1b); L(2)=(P)-1,1'-binaphthalene-2,2'-bis(oxamate) with M=Mn (2a) and Co (2b)] and the analogous racemic chains of formula [MCuL(3)(S)(m)(H(2)O)(n)]·aS·bH(2)O [L(3)=1,1'-binaphthalene-2,2'-bis(oxamate) with M=Mn (3a) and Co (3b)] have been prepared by reaction of the corresponding dianionic oxamatocopper(II) complex [Cu(L(x))](2-) with Mn(2+) or Co(2+) cations in either dimethylformamide (DMF) or dimethyl sulfoxide (DMSO). Solid circular dichroism (CD) spectra of the bimetallic chain compounds were reco…
Pharmacological blockade of the fatty acid amide hydrolase (FAAH) alters neural proliferation, apoptosis and gliosis in the rat hippocampus, hypothal…
2015
Endocannabinoids participate in the control of neurogenesis, neural cell death and gliosis. The pharmacological effect of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which limits the endocannabinoid degradation, was investigated in the present study. Cell proliferation (phospho-H3(+) or BrdU(+) cells) of the main adult neurogenic zones as well as apoptosis (cleaved caspase-3(+)), astroglia (GFAP(+)), and microglia (Iba1(+) cells) were analyzed in the hippocampus, hypothalamus and striatum of rats intraperitoneally treated with URB597 (0.3 mg/kg/day) at one dose/4-days resting or 5 doses (1 dose/day). Repeated URB597 treatment increased the plasma levels of the N-acylethanolamine…
Investigating the influence of climate changes on rodent communities at a regional-scale (MIS 1-3, southwestern France).
2016
25 pages; International audience; Terrestrial ecosystems have continuously evolved throughout the Late Pleistocene and theHolocene, deeply affected by both progressive environmental and climatic modifications, aswell as by abrupt and large climatic changes such as the Heinrich or Dansgaard-Oeschgerevents. Yet, the impacts of these different events on terrestrial mammalian communities arepoorly known, as is the role played by potential refugia on geographical species distributions.This study examines community changes in rodents of southwestern France between50 and 10 ky BP by integrating 94 dated faunal assemblages coming from 37 archaeologicalsites. This work reveals that faunal distributi…
Neatņemamās daļas tiesīgie un to atstumšana no mantojuma
2016
Neatņemamā daļa, neatņemamās daļas tiesīgie un to atstumšana- šie tiesību institūti Latvijas Republikas Civillikumā regulēti ir diezgan sarežģīti. Svarīgi ir saprast šo institūtu nozīmi un vēsturisko attīstību. Šī iemesla dēļ tika apkopota pieejamā literatūra, tiesu prakse un ārvalstu tiesību normas par šo tematu.Darba mērķis ir identificēt problēmjautājumus saistībā ar šiem institūtiem, kā arī piedāvāt labojumus vai papildinājumus Latvijas Republikas Civillikumā, lai tas būtu vieglāk pieņemams Latvijas sabiedrībai, un cilvēkiem, kuri nav apmācīti juristi, nerastos nevajadzīgi pārpratumi un strīdi.Šo institūtu mērķis ir noteikt tiesības testatora tuvākajiem radiniekiem, kas ir neatņemamās d…
Septins 2, 7 and 9 and MAP4 colocalize along the axoneme in the primary cilium and control ciliary length
2013
International audience; Septins are a large, evolutionarily conserved family of GTPases that form hetero-oligomers and interact with the actin-based cytoskeleton and microtubules. They are involved in scaffolding functions, and form diffusion barriers in budding yeast, the sperm flagellum and the base of primary cilia of kidney epithelial cells. We investigated the role of septins in the primary cilium of retinal pigmented epithelial (RPE) cells, and found that SEPT2 forms a 1:1:1 complex with SEPT7 and SEPT9 and that the three members of this complex colocalize along the length of the axoneme. Similar to observations in kidney epithelial cells, depletion of cilium-localized septins by siRN…
Different roles for KIF17 and kinesin II in photoreceptor development and maintenance.
2009
Kinesin 2 family members are involved in transport along ciliary microtubules. In Caenorhabditis elegans channel cilia, kinesin II and OSM-3 cooperate along microtubule doublets of the axoneme middle segment, whereas OSM-3 alone works on microtubule singlets to elongate the distal segment. Among sensory cilia, vertebrate photoreceptors share a similar axonemal structure with C. elegans channel cilia, and deficiency in either kinesin II or KIF17, the homologue of OSM-3, results in disruption of photoreceptor organization. However, direct comparison of the two effects is confounded by the use of different species and knockdown strategies in prior studies. Here, we directly compare the effects…
S-Detect characterization of focal solid breast lesions: a prospective analysis of inter-reader agreement for US BI-RADS descriptors
2020
Background: To assess inter-reader agreement for US BI-RADS descriptors using S-Detect: a computer-guided decision-making software assisting in US morphologic analysis. Methods: 73 solid focal breast lesions (FBLs) (mean size: 15.9 mm) in 73 consecutive women (mean age: 51 years) detected at US were randomly and independently assessed according to the BI-RADS US lexicon, without and with S-Detect, by five independent reviewers. US-guided core-biopsy and 24-month follow-up were considered as standard of reference. Kappa statistics were calculated to assess inter-operator agreement, between the baseline and after S-Detect evaluation. Agreement was graded as poor (≤ 0.20), moderate (0.21–0.40)…
