Pseudoartrosis congénita bilateral de la clavícula: a propósito de un caso familiar

Presentamos una paciente de nueve meses con pseudoartrosis congénita bilateral de ambas clavículas, cuya madre presenta el mismo cuadro. Dicho cuadro es una entidad rara, pobremente documentada en la ortopedia pediátrica. La etiología y patogenia aún permanece oscura. La apariencia clínico-radiológica consiste en la ausencia desde el nacimiento de un defecto de unión a nivel del tercio medio clavicular característico. El diagnóstico diferencial debe hacerse con las fracturas perinatales, pseudoartrosis postraumáticas y disostosis cleido-craneales.The case of a female patient of nine months of are and her mother, 41-year-old showing a Congenital Bilateral Pseudoarthrosis of the clavicle are presented. This is a rare entity that has been poorly documented in paediatrics orthopedics literature. The etiology and pathogenesis still remain unclear. The clinical and radiological appearance are characteristic. Differential diagnosis lies between postpartum fractures, postraumatic pseudoarthrosis, and cleidocraneal dysostosis

Biodiversity accounting and reporting: A systematic literature review and bibliometric analysis

Towards the improvement of environmental sustainability and the conservation of biodiversity, organisations are increasingly aware of the importance of reporting their impacts on biodiversity and the conservation plans undertaken. Biodiversity accounting and reporting are relevant for developing organisational practices oriented towards environmental sustainability, promoting cleaner management policies with less impact on the environment. Biodiversity accounting research has attracted scholars in business management and accounting, and as a result, the literature in the field has grown in recent years. This study analyses the intellectual structure of the biodiversity accounting and management discipline through a systematic literature review, along with bibliometric techniques based on a co-word analysis of the main keywords included in 63 publications. The results reveal five thematic clusters: one motor cluster (sustainability), two transversal clusters (biodiversity reporting, corporate biodiversity management) and two isolated clusters (environmental protection, emancipatory accounting). In addition, the content of the selected papers is analysed and promising research paths are found, such as the need for more robust quantitative analyses or the development of new forms of emancipatory accounting. The study discusses the main insights from the analysis, proposes future research directions and provides practical implications for biodiversity protection and environmental sustainability. © The Author

La intervención escolar en los trastornos del espectro autista

[Resumen] La integración social y escolar de los niños con trastorno del espectro autista es un hecho consumado desde los últimos años. Sin embargo, su práctica debe considerar una serie de adaptaciones y ajustes. Las limita- ciones que manifiestan estos niños son muy variadas y heterogéneas, lo que en la práctica escolar debe traducirse por una actuación educativa que de respuesta a sus necesidades y habilidades. El objetivo del presente artícu- lo es revisar algunas cuestiones centrales para la intervención psicoeducativa de los niños con trastorno de espectro autista, las modalidades de escolarización y las adapta- ciones tanto curriculares como sociales. Se proponen algunas mejoras para la puesta en marcha efectiva de las diferentes medidas educativas a adoptar.[Abstract] The social and school integration of chil- dren with autistic spectrum disorders is a fait accompli in recent years. However, its practi- ce must consider a series of adaptations and adjustments. These children show a variety of heterogeneous limitations, what in the school practice must be translated into an educative performance that responds to their needs and abilities. The goal of this article is to revise some vital questions for the psychoeducative intervention in children with autistic spectrum disorders, for the different schooling systems and for the curricular or social adaptations. Improvements are proposed in order to carry out an effective launch of the different educa- tive measures that must be taken

Alfalfa but not milk in lamb's diet improves meat fatty acid profile and a-tocopherol content

To establish animal feeding recommendations, it is required to quantify whether the effects of combining dietary alfalfa and milk on meat composition of light lambs are overlapped or independent. This experiment aimed to evaluate the separate effects of dietary alfalfa and milk access on the light lamb carcass quality (10–11 kg), meat colour, chemical composition, fatty acid profile and a-tocopherol content. Thirty-two lambs were assigned to one of four treatments in a 2 × 2 factorial design. The factors were the inclusion of dietary forage (grazed alfalfa vs. concentrate-fed indoors) and lactation length (weaning at a target live-weight of 13 kg vs. suckling until slaughter at 22–24 kg). Dietary alfalfa but not milk supply improved conjugated linoleic acid isomers (CLA), omega-3 fatty acids and a-tocopherol contents in lamb meat without affecting meat colour attributes. Milk supply affected more the fatty acid profile (more saturated) than the a-tocopherol content of meat. Thus, dietary alfalfa improved CLA, omega-3 fatty acids and a-tocopherol content in light lamb without affecting the meat colour, whereas lengthening the lactation period did not provide benefits in terms of meat colour or healthy nutrient composition

Universal class of type-IIB flux vacua with analytic mass spectrum

We report on a new class of flux vacua generically present in Calabi-Yau compactifications of type-IIB string theory. At these vacua, the mass spectrum of the complete axiodilaton/complex structure sector is given, to leading order in a' and g(s), by a simple analytic formula independent of the choice of Calabi-Yau. We provide a method to find these vacua and construct an ensemble of 17,054 solutions for the Calabi-Yau hypersurface WP[1,1,1,6,9]4, where the masses of the axiodilaton and the 272 complex structure fields can be explicitly computed.This work is supported by the Spanish Ministry MCIU/AEI/FEDER Grant No. PGC2018-094626-B-C21, the Basque Government Grant No. IT-979-16, and the Basque Foundation for Science (IKERBASQUE).

Towards a Complete Mass Spectrum of Type-IIB Flux Vacua at Large Complex Structure

The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible. A common strategy to solve this problem is to consider Calabi-Yau manifolds with discrete symmetries, which effectively reduce the number of moduli and make the computation of the truncated Effective Field Theory possible. In this approach, however, the couplings (e.g., the masses) of the truncated fields are left undetermined. In the present paper we discuss the tree-level mass spectrum of type-IIB flux compactifications at Large Complex Structure, focusing on models with a reduced one-dimensional complex structure sector. We compute the tree-level spectrum for the dilaton and complex structure moduli, including the truncated fields, which can be expressed entirely in terms of the known couplings of the reduced theory. We show that the masses of this set of fields are naturally heavy at vacua consistent with the KKLT construction, and we discuss other phenomenologically interesting scenarios where the spectrum involves fields much lighter than the gravitino. We also derive the probability distribution for the masses on the ensemble of flux vacua, and show that it exhibits universal features independent of the details of the compactification. We check our results on a large sample of flux vacua constructed in an orientifold of the Calabi-Yau WP[1,1,1,1,4]4. Finally, we also discuss the conditions under which the spectrum derived here could arise in more general compactifications

Growth, water relations and ion accumulation in Phlomis purpurea plants under water deficit and salinity

The effect of different levels of water deficit and salinity on physiological and morphological alterations in Phlomis purpurea plants was studied to evaluate their adaptability to such conditions. P. purpurea plants growing under greenhouse conditions were subjected to four irrigation treatments between November and May 2008: control (C, 1 dS m-1), moderate water deficit (MWD, 1dS m-1, 60% of the control), severe water deficit (SWD, 1 dS m-1, 40% of the control) and saline (S, 4 dS m-1). Aerial dry weight decreased with salinity, response that was more marked in the water deficit treatments, especially SWD. Stem diameter and leaf number were similarly reduced in both water deficit treatments, while leaf area also decreased in saline treated plants. Throughout the experiment, plant height was similar in both control and saline treated plants and was inhibited 10 weeks after application of the deficit irrigation onwards. Only at the end of the experiment were there significant differences in plant height between all treatments. Plants irrigated with saline water had higher Na+ concentrations in their leaves than in their roots and shoots, while Cl- concentrations were similar in leaves and roots, suggesting some resistance to the movement of the latter ions from root to shoots. The accumulation of salt in the leaves was associated with osmotic adjustment, which maintained midday leaf turgor in saline treated plants. However, no osmotic adjustment was observed in plants submitted to water stress. The results indicate that the effect of osmotic stress due to water deficit was more severe than the toxic effect of salt.This work was supported by the projects: CICYT (AGL 2008-05258-C02-1-2), CDTI (IDI-20070868) and Convenio de la Consejería de Agricultura y Agua de la Región de Murcia-UPCT-CEBAS, 2008.Peer Reviewe

Enhancing the hydrogen transfer catalytic activity of hybrid carbon nanotube-based NHC–iridium catalysts by increasing the oxidation degree of the nanosupport

CVD-grown multiwalled carbon nanotubes were purified by applying four different treatments with increasing oxidation severity. The growing severity of the treatment results in progressive oxygen functionalization of the surface along with introduction of an increasing quantity of defects on the carbon nanotube walls. Iridium–N-heterocyclic carbene complexes were covalently anchored to those oxidized surfaces through their surface carboxylic acids via acetyl linkers. The carbon nanotube-based iridium–NHC hybrid materials developed are active in the hydrogen-transfer reduction of cyclohexanone to cyclohexanol with 2-propanol/KOH as hydrogen source but with rather different activity. The catalytic activity of the hybrid catalysts is strongly influenced by the type and amount of oxygenated functionalization resulting from the treatment applied to the support, being the most active and the most oxidized material

Characterisation of agricultural residues used as a source of fibres for fibre-cement production

Nowadays, certain components of non-wood annual plants such as corn stalk and industrial hemp core are considered waste materials or used in low value applications; both by-products have a very low cost. On the other hand, given the large quantities of these materials generated worldwide and their renewable character, it is reasonable to explore new routes for their exploitation. The aim of this paper is to study the potential of both corn stalk (Zea Mays L.) and industrial hemp core (Cannabis Sativa L.) fibres as a renewable source of cellulose fibres in the production of fibre-cement. For each source of fibres, a number of chemical cooking treatments were studied. The morphological properties of the fibres were determined using a scanning electron microscope and a fibre and pulp morphological analyser. Pulp refining was carried out in a PFI mill to improve the characteristics of the fibres. In the case of corn fibres, different degrees of refining were applied. The fibre flocculation process was investigated using several polyacrylamides. The process was studied by monitoring the chord size distribution in real time by means of a focused beam reflectance measurement probe. The results indicated both pulps can be used for the production of fibre-cement, having the two types of pulp morphological similarities with the pine fibres currently used. Through the flocculation process it was concluded the floc size depends on the length of the fibres
