Forage Yield and Soil Moisture Content in \u3cem\u3ePanicum Maximum\u3c/em\u3e cv. Tanzania Monoculture and in a Mixture with \u3cem\u3eLeucaena Leucocephala\u3c/em\u3e with Different Densities in Mexico

Cattle production is limited by forage availability during the dry season since water and soil fertility are the main factors limiting production. Leucaena leucocephala has good nutritive value (24-30% CP). It can stand drought and grazing and so its introduction into pastures is recommended as an alternative to forage production during the dry season. The aim of this study was to assess the effect of the introduction of L. leucocephala with different densities on biomass production of P. maximum and soil water content

High-dimensional decoy-state quantum key distribution over 0.3 km of multicore telecommunication optical fibers

Multiplexing is a strategy to augment the transmission capacity of a communication system. It consists of combining multiple signals over the same data channel and it has been very successful in classical communications. However, the use of enhanced channels has only reached limited practicality in quantum communications (QC) as it requires the complex manipulation of quantum systems of higher dimensions. Considerable effort is being made towards QC using high-dimensional quantum systems encoded into the transverse momentum of single photons but, so far, no approach has been proven to be fully compatible with the existing telecommunication infrastructure. Here, we overcome such a technological challenge and demonstrate a stable and secure high-dimensional decoy-state quantum key distribution session over a 0.3 km long multicore optical fiber. The high-dimensional quantum states are defined in terms of the multiple core modes available for the photon transmission over the fiber, and the decoy-state analysis demonstrates that our technique enables a positive secret key generation rate up to 25 km of fiber propagation. Finally, we show how our results build up towards a high-dimensional quantum network composed of free-space and fiber based linksComment: Please see the complementary work arXiv:1610.01812 (2016

Root Density in \u3cem\u3ePanicum maximum\u3c/em\u3e cv. Tanzania Monoculture and in a Mixture with \u3cem\u3eLeucaena leucocephala\u3c/em\u3e with Different Densities in Mexico

In Yucatan cattle production is limited by forage availability during the dry season. L. leucocephala has good nutritive value (24 - 30% CP) and can stand drought and grazing, therefore its use in mixture with grasses is recommended. However, in association both species could compete for light, water and nutrients. The aim of this study was to assess the effect of introduction of L. leucocephala with different densities on root density of P. maximum

Accidental ulcer infestation due Tenebrio molitor in an AIDS patient: canthariasis

Canthariasis is a disease of humans caused by the infestation of beetle larvae. It is the second important insectal disease after myiasis. Several species of beetles are reported to cause the disease in gastrointestinal tract, urogenital system, nasal sinuses, ears and faces of mammals. The mealworm beetle, Tenebrio molitor, a species of darkling beetle, is a widespread pest that usually feeds on stored grain. The human infestation by this worm is extremely rarely reported, we described a case of T. molitor infestation in a AIDS patient in Colombia

Covalent Cross-Linking of 2H-MoS2 Nanosheets

The combination of 2D materials opens a wide range of possibilities to create new-generation structures with multiple applications. Covalently cross-linked approaches are a ground-breaking strategy for the formation of homo or heterostructures made by design. However, the covalent assembly of transition metal dichalcogenides flakes is relatively underexplored. Here, a simple covalent cross-linking method to build 2H-MoS2–MoS2 homostructures is described, using commercially available bismaleimides. These assemblies are mainly connected vertically, basal plane to basal plane, creating specific molecular sized spaces between MoS2 sheets. Therefore, this straightforward approach gives access to the controlled connection of sulfide-based 2D materials

Necropulpectomía : tratamiento conservador en necrosis pulpar de un canino en un pastor alemán

En este trabajo se pone en práctica la endodoncia en la especie canina, aplicada a una lesión traumática dental a nivel de un canino en un perro de adiestramiento. La terapéutica se realiza en dos fases: provisional y definitiva; en ambos casos encaminadas hacia el tratamiento conservador de la pieza. Se describe la técnica utilizada para la necropulpectomía y posterior obturación con amalgama de plata de la cavidad pulpar.An endodoncy was practiced to trained dog that had had a traumatic injury affecting a canine tooth. The therapy was carried out in two phases: provisional and definitive. In both cases the purpose was to preserve the tooth. The applied technique for necropulpectomy and following filling of the pulp cavity whit silver amalgam is described
