Microbial enrichment culture responsible for the complete oxidative biodegradation of 3‑Amino-1,2,4-triazol-5-one (ATO), the reduced daughter product of the insensitive munitions compound 3‑Nitro-1,2,4-triazol-5-one (NTO)
No full text3-Nitro-1,2,4-triazol-5-one (NTO) is one of the main ingredients of many insensitive munitions, which are being used as replacements for conventional explosives. As its use becomes widespread, more research is needed to assess its environmental fate. Previous studies have shown that NTO is biologically reduced to 3-amino-1,2,4-triazol-5-one (ATO). However, the final degradation products of ATO are still unknown. We have studied the aerobic degradation of ATO by enrichment cultures derived from the soil. After multiple transfers, ATO degradation was monitored in closed bottles through measurements of inorganic carbon and nitrogen species. The results indicate that the members of the enrichment culture utilize ATO as the sole source of carbon and nitrogen. As ATO was mineralized to CO₂, N₂, and NH₄⁺, microbial growth was observed in the culture. Co-substrates addition did not increase the ATO degradation rate. Quantitative polymerase chain reaction analysis revealed that the organisms that enriched using ATO as carbon and nitrogen source were Terrimonas spp., Ramlibacter-related spp., Mesorhizobium spp., Hydrogenophaga spp., Ralstonia spp., Pseudomonas spp., Ectothiorhodospiraceae, and Sphingopyxis. This is the first study to report the complete mineralization of ATO by soil microorganisms, expanding our understanding of natural attenuation and bioremediation of the explosive NTO.Journal ArticleFinal article publishe
The usage of the conjunction “jog” in students' bachelor theses.
No full textTo date, few studies have been conducted on the use of the conjunction jog in the current Lithuanian language. It is observed that the cases described in the grammar deviate from the actual use of this conjunction. For this reason, the following aim was put forward during the research: to answer the question, in which cases in the students’ final papers the conjunction jog is used and how it differs from the tendencies described in the grammar. The research material was a corpus of bachelor’s degree’s students’ papers (collected by Vilma Zubaitienė, Gintarė Judžentytė-Šinkūnienė, Eglė Gudavičienė, Lina Plaušinaitytė and Skaistė Volungevičiūtė and used in monograph Studentų darbų fraziškumas). Due to the limited scope of research, it was chosen to examine the papers of 3 fields of science – biomedical, social, and technological sciences. Using the AntConc program, all instances of jog usage were selected from the corpus and classified according to the type of the sub-sentence (complement, relative, adverbial). The paper was divided into sections, first, according to the research field, then divided according to the type of sub-sentence, and specific use cases are discussed. The research revealed that the conjunction jog is most often used in the papers of social science students, and the least often in the papers of technology field students. The peculiarities of the use of sentences are similar in all fields of work – most often the conjunction jog is used to attach complement sentences, least often – adverbial sentences. Furthermore, in these papers conjunction jog has been used to attach adverbial sentences of method, quantity, reason, condition, purpose and place. According to the current rules, conjunction jog can not be used to attach sub-sentences of purpose, but such cases have been found in students’ papers. The grammar does not describe relative sentences with conjunction jog – still, such examples are also found in this paper. The author of this paper understands that the research is limitated, as the following aspects were not included in the research: if conjunction jog was used in the sentences as synonym for kad; if sentences, where conjunction jog was used, are found in papers of different author or the same ones; the change by year has not been studied, so it is impossible to draw a firm conclusion as to whether consumption is increasing; the data studied is from 2010 to 2016, so now results may have changed
Architecture validation of VFP control for the WiNC2R platform
No full textA Cognitive Radio processing requires intelligent transceiver which can be easily programmed and reconfigured dynamically to support multiple protocols. The Winlab Network Centric Cognitive Radio (WiNC2R) platform is based on the concept of Virtual Flow Pipelining Paradigm. WiNC2R can support per packet protocol adaption through the reconfiguration of function sequencing. Since WiNC2R platform can be programmed by adding additional functions in software, and flow sequencing reprogramming architecturally supported in hardware, it can easily support future protocols. The latest version of WiNC2R has advanced shared VFP control unit, cluster based SoC architecture with all the processing engines in an 802.11a like OFDM transmitter flow. It is very important to characterize the VFP overhead with the realistic protocol processing examples to understand the performance and cost penalties of added flexibility, and establish the base for the comparison with Software Defined Radio approach. The performance analysis of the VFP will give detailed insight about the various latencies involved in the VFP processing. VFP Architecture is validated to see that the current implementation does meet the requirements of the WiNC2R platform. This performance analysis will help in characterizing VFP overhead under varying throughput requirements. Architectural validation of VFP will characterize certain parameters of the system programming, like reschedule period, guard time, etc.M.S.Includes bibliographical referencesby Akshay Jo
Recepció az antik jogokban és a római jog = Reception in the Laws of the Antiquity and Roman Law
No full textA jogtudósok a korábbiakban nem fordítottak kellő figyelmet az összehasonlító jog előzményeire az ókori Mediterráneum térségében. A tanulmány szerzője áttekinti a római jog fogalmai alkalmazásának lehetőségét a klasszikus, görög-római antikvitás jogai elemzésében.
Az esszé vizsgálja a nemzetközi gazdasági és államközi kapcsolatok hatását a Földközi-tenger
térsége államainak jogára. A szerző hangsúlyozza továbbá a római jog ma is kimutatható
jelentőségét a magánjog kodifikálásának területén. | Legal scholars did not pay much attention to the antecedents of comparative law in the laws
of the ancient Mediterraneum. The author of the article examines the possibility of the application of concepts and notions of Roman law in the field of analysis of the laws of classical i.e., Graeco-Roman Antiquity. The study examines the influence of the international
economic and political relations on the laws of the ancient Mediterranean world. The author
emphasizes the contemporary significance of Roman law in the field of the codification of
private law
