Efecto de la cocción óhmica seguida de un método de cocción infrarrojo sobre la oxidación de lípidos y la formación de hidrocarburos aromáticos policíclicos (HAP) de músculo de vaca
In this study, the effects of ohmic cooking alone and a consecutive application of ohmic and infrared cooking on lipid oxidation and polycyclic aromatic hydrocarbon (PAH) formation in beef was investigated. In consecutive cooking, samples were first cooked ohmically at 40, 55 and 70 Volt for 7 minutes, then infrared cooking was applied to each side of ohmically cooked beef samples at 3 different temperatures (325, 375 and 425 °F) for 3 minutes. The thiobarbituric acid reactive substance (TBARS) levels of the samples were found between 0.31 and 1.74 mg MDA/kg. Increasing the voltage level in ohmic cooking caused a significant (P < 0.05) increase in the TBARS value. In the consecutive application of ohmic and infrared cooking, infrared cooking temperature caused a significant (P < 0.05) increase in the TBARS value at the same voltage levels. In this study, working with 40 and 55 Volts for ohmic cooking alone and 40 V-325 °F, 40V-375 °F settings for ohmic-infrared cooking gave a generally acceptable threshold level for TBARS value (1 mg/kg). About 12 polycyclic aromatic hydrocarbons (PAHs) were detected in the cooked beef by ultra-performance liquid chromatography fluorescence detector (UPLC-FD). Benzo(a)pyrene (BaP), which is the most common PAH, was detected at between 1.2514 and 1.4392 μg/kg and 4 PAH (sum of Benzo(a)pyrene, Chrysene, Benz(a)anthracene, Benz(b)fluoranthene) levels were detected at between 1.2514- 3.7844 μg/kg. The results of PAHs were reasonably below the European Commission regulation limits, which are very important and indicate that the cooking processes applied in this study are safe.En este estudio se investigaron los efectos de la cocción óhmica sola y la aplicación consecutiva de cocción óhmica e infrarroja sobre la oxidación de lípidos y la formación de hidrocarburos aromáticos policíclicos (HAP) en carne de res.

Los niveles de las sustancias reactivas al ácido tiobarbitúrico (TBARS) de las muestras se encontraron entre 0,31 y 1,74 mg de MDA/kg. Aumentar el nivel de voltaje en la cocción óhmica ocasiona un aumento significativo (
Towards Federalizing U.S. International Commercial Arbitration Law
Leaves of Juglans regia L. collected from two different locations [Adana (A) and Ankara (BA from Turkey were subjected to hydrodistillation in a Clevenger type apparatus to yield the essential oils (EOs). GC/MS and GC-FID analyses revealed that the A EO was rich in thymol (23.1%), while caryophyllene oxide (33.8%) was found as the main constituent of B EO. Both contained beta-eudesmol (1.4% - 9.5%), (E)-geranyl acetone (3.7% - 5.8%) and the eudesmane type constituent juglaterpene A (3.1% - 11.0%). Using a HP Innowax preparative capillary column connected to a preparative fraction collector, an unknown constituent, juglaterpene A (1, 11-hydroxy-2,4-cycloeudesmane), was isolated in a rapid one-step manner with > 94.0% purity. Structure determination was accomplished from 1D- and 2D-NMR spectroscopic data. Oil B demonstrated significant larvicidal activity against 1st instar Aedes aegypti L
Marking method for dung beetles (Coleoptera: Scarabaeinae) and its implementation in Colombian Andes
We describe a new inexpensive and simple method for marking large dung beetles (>10 mm), which consists in tattooing a consecutive number on their elytra or pronotum with a Mototool. The recapture rate (18.5% of 1886 marked individuals) throughout five months shows high durability of the mark without affecting the integrity of the individual
De Novo Transcriptome Assembly and Comparative Analysis Elucidate Complicated Mechanism Regulating Astragalus chrysochlorus Response to Selenium Stimuli
Astragalus species are medicinal plants that are used in the world for years. Some Astragalus species are known for selenium accumulation and tolerance and one of them is Astragalus chrysochlorus, a secondary selenium accumulator. In this study, we employed Illumina deep sequencing technology for the first time to de novo assemble A. chrysochlorus transcriptome and identify the differentially expressed genes after selenate treatment. Totally, 59,656 unigenes were annotated with different databases and 53,960 unigenes were detected in NR database. Transcriptome in A. chrysochlorus is closer to Glycine max than other plant species with 43,1 percentage of similarity. Annotated unigenes were also used for gene ontology enrichment and pathway enrichment analysis. The most significant genes and pathways were ABC transporters, plant pathogen interaction, biosynthesis of secondary metabolites and carbohydrate metabolism. Our results will help to enlighten the selenium accumulation and tolerance mechanisms, respectively in plants
Optimizing decomposition of software architecture for local recovery
Cataloged from PDF version of article.The increasing size and complexity of software systems has led to an amplified number of potential failures and as such makes it harder to ensure software reliability. Since it is usually hard to prevent all the failures, fault tolerance techniques have become more important. An essential element of fault tolerance is the recovery from failures. Local recovery is an effective approach whereby only the erroneous parts of the system are recovered while the other parts remain available. For achieving local recovery, the architecture needs to be decomposed into separate units that can be recovered in isolation. Usually, there are many different alternative ways to decompose the system into recoverable units. It appears that each of these decomposition alternatives performs differently with respect to availability and performance metrics. We propose a systematic approach dedicated to optimizing the decomposition of software architecture for local recovery. The approach provides systematic guidelines to depict the design space of the possible decomposition alternatives, to reduce the design space with respect to domain and stakeholder constraints and to balance the feasible alternatives with respect to availability and performance. The approach is supported by an integrated set of tools and illustrated for the open-source MPlayer software

Re A (A Child) and the United Kingdom Code of Practice for the Diagnosis and Confirmation of Death: Should a Secular Construct of Death Override Religious Values in a Pluralistic Society?
The determination of death by neurological criteria remains controversial scientifically, culturally, and legally, worldwide. In the United Kingdom, although the determination of death by neurological criteria is not legally codified, the Code of Practice of the Academy of Medical Royal Colleges is customarily used for neurological (brainstem) death determination and treatment withdrawal. Unlike some states in the US, however, there are no provisions under the law requiring accommodation of and respect for residents’ religious rights and commitments when secular conceptions of death based on medical codes and practices conflict with a traditional concept well-grounded in religious and cultural values and practices. In this article, we analyse the medical, ethical, and legal issues that were generated by the recent judgement of the High Court of England and Wales in Re: A (A Child) [2015] EWHC 443 (Fam). Mechanical ventilation was withdrawn in this case despite parental religious objection to a determination of death based on the code of practice. We outline contemporary evidence that has refuted the reliability of tests of brainstem function to ascertain the two conjunctive clinical criteria for the determination of death that are stipulated in the code of practice: irreversible loss of capacity for consciousness and somatic integration of bodily biological functions
Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding
Sorghum is emerging as a model crop for functional genetics and genomics of tropical grasses with abundant uses, including food, feed, and fuel, among others. It is currently the fifth most significant primary cereal crop. Crops are subjected to various biotic and abiotic stresses, which negatively impact on agricultural production. Developing high-yielding, disease-resistant, and climate-resilient cultivars can be achieved through marker-assisted breeding. Such selection has considerably reduced the time to market new crop varieties adapted to challenging conditions. In the recent years, extensive knowledge was gained about genetic markers. We are providing an overview of current advances in sorghum breeding initiatives, with a special focus on early breeders who may not be familiar with DNA markers. Advancements in molecular plant breeding,
genetics, genomics selection, and genome editing have contributed to a thorough understanding of DNA markers, provided various proofs of the genetic variety accessible in crop plants, and have substantially enhanced plant
breeding technologies. Marker-assisted selection has accelerated and precised the plant breeding process, empowering plant breeders all around the world
