Enhancing naked oat (Avena nuda L.) productivity with minimal indirect nitrogen loss and maximum nitrogen use efficiency through integrated use of different nitrogen sources

Oat (Avena nuda L.) is a nutritious grain crop, rich in dietary fibers and phytochemicals. Application of efficient nitrogen (N) sources and dose is very important to obtain higher crop productivity and to achieve environmental sustainability. The exploitation of natural beneficial microbes and organic nitrogen in combination with chemical nitrogen would be effective to boost...

Supuestos básicos del enfoque de competencias en educación superior: La educación veterinaria como marco de análisis

The main objective of this article is to extend the knowledge of several basic assumptions, related to the competency-based approach in higher education, regarding their consistency or, otherwise, inconsistency, under different rationales for its use and application. The research was developed on the basis of three analytical elements: a) the conceptual framework provided by a...

Two-quartet kit* G-quadruplex is formed via double-stranded pre-folded structure

In the promoter of c-KIT proto-oncogene, whose deregulation has been implicated in many cancers, three G-rich regions (kit1, kit* and kit2) are able to fold into G-quadruplexes. While kit1 and kit2 have been studied in depth, little information is available on kit* folding behavior despite its key role in regulation of c-KIT transcription. Notably, kit* contains consensus sites...

Implicaciones de Ctenopharyngodon idella en la comunidad de peces del río Lacanjá, Chiapas

The fish community in the Lacanja river was sampled to assess the relative abundance of grass carp Ctenopharyngodon idella. Five different sites were carried out between March and May 1997. A total of 1450 speciments were collected representing 37 species and 15 families; Cichlidae was the dominant family with 15 species. Similarity analysis suggested two different fish...

Disentangling link formation and dissolution in spatial networks: An Application of a Two-Mode STERGM to a Project-Based R&D Network in the German Biotechnology Industry

The analysis of spatial networks’ evolution has predominantly concentrated on the formation process of links. However, the evolution of networks is similarly shaped by the dissolution of links, which has thus far received considerably less attention. The paper presents separable temporal exponential random graph models (STERGMs) as a promising method in this context, which allows...

Enough is Enough: Congressional Solutions to Curb Gun Violence in America's K-12 Schools

Almost two decades after the massacre at Columbine High School, shootings at our nation’s K-12 schools have become the new normal. More than 350 incidents of gunfire on school campuses have occurred in just the past five years. These have occurred with two federal laws on the books aimed to keep guns away from school campuses. This Article analyzes the Constitution’s Article I...

18 U.S.C. § 3553(a)’s Undervalued Sentencing Command: Providing a Federal Criminal Defendant with Rehabilitation, Training, and Treatment in “the Most Effective Manner”

The vast majority of federal criminal defendants are sentenced to prison, and non-incarceration sentences have become vanishingly small. During the sentencing process, federal district court judges are required to consider what sentence will provide the defendant with necessary rehabilitation and treatment in the most effective manner pursuant to 18 U.S.C. § 3553(a)(2)(d). Courts...

Hippocampus whitei Bleeker, 1855, a senior synonym of the southern Queensland seahorse H. procerus Kuiter, 2001: molecular and morphological evidence (Teleostei, Syngnathidae)

The taxonomic status of the seahorse Hippocampus procerus Kuiter, 2001, type locality Hervey Bay, QLD, Australia, was re-examined based on its strong morphological similarity and geographical proximity to its congener H. whitei Bleeker, 1855, a species recorded in ten estuaries of New South Wales, Australia. Kuiter (2001) distinguished H. procerus from H. whitei by a taller...

Megabahita Linnavuori & Delong (Homoptera, Cicadellidae, Deltocephalinae): descrição de três espécies novas

The genus Megabahita Linnavuori & DeLong, 1978 is redefined based on the type species, M. irrorata (Osborn, 1923). A checklist is added and three new species are described: M. mineira sp.n., M. danunciae sp.n. and M. spatulata sp.n., all from Brazil.

A closed-loop, music-based brain-computer interface for emotion mediation

Emotions play a critical role in rational and intelligent behavior; a better fundamental knowledge of them is indispensable for understanding higher order brain function. We propose a non-invasive brain-computer interface (BCI) system to feedback a person’s affective state such that a closed-loop interaction between the participant’s brain responses and the musical stimuli is...

Influência da origem do cloreto de potássio utilizado em extrações de amostras de solos, nos resultados de alumínio trocável

Variable values of aluminum extracted with lN solutions of the reagent were observed. It was shown that the problem was related to some buffering of the solutions, probably due to presence of potassium carbonate, which precipitated aluminum. Acidifying and boiling of the solutions of potassium chloride minimized this problem.

The competencies of the shift leader in the intensive care unit setting, in a private hospital group in South Africa

Newly qualified intensive care nurses are forced into positions of authority and responsibility as shift leaders at an early stage and are not given a chance to consolidate their new knowledge with practice. They have to be responsible and accountable not only for their own actions, but also for those of their staff. The purpose of this study was to explore and describe the...

Less invasive pilonidal sinus surgical procedures

Pilonidal disease can be treated by less invasive methods such as simple mechanical cleansing of the sinus and cavity of hairs and granulation tissue eventually supplemented by filling the space with an antiseptic or sclerosing agent like phenol (forbidden in Germany due to its toxicity) or space-holding fibrin glue. Minimal excision or debridement of the sinus and/or cavity...

Trópicos, microbios y vectores

The article analyzes how Argentinean and Brazilian researchers designed their tropical disease research programs in the late 19th and early 20th centuries. Even though Brazilian and Argentinean hygiene were direct descendants of Pasteurian programs and principles, Brazil addressed its public health problems through a new research agenda that embraced bacteriology, parasitology...

Seasonal and interpopulational phenotypic variation in morphology and sexual signals of Podarcis liolepis lizards

Widespread species often show extensive phenotypic variation due to the contrasting abiotic and biotic factors that shape selective pressures in different environments. In this context, the gradual and predictable patterns of variation in climatic and environmental conditions found in mountain areas offer a great opportunity to explore intraspecific phenotypic variation. For...

Evaluation of a rapid immunodiagnostic test kit for detection of African lyssaviruses from brain material

A rapid immunodiagnostic test kit was evaluated against a selection of isolates of lyssavirus genotypes occurring in Africa. The test was carried out in parallel comparison with the fluorescent antibody test (FAT) and isolates representing previously established phylogenetic groups from each genotype were included. The specificity of the rapid immunodiagnostic test compared...
