Abstract:
AbstractSeventeen examples are given of Cataclysmic Variable (CV) stars possessing both Dwarf Nova Oscillations (DNOs) and Quasi-Periodic Oscillations (QPOs). These form an extension of the X-Ray Two-QPO correlation to frequencies three orders of magnitude lower. We draw attention to the existence of a second type of DNO in CVs, which is probably caused by magnetically channelled accretion onto the white dwarf.

Abstract:
Most macroeconomic studies predict a decline in final energy demand and the use of natural gas in the heating sector in Europe. In the course of building retrofitting, gas-based heating systems are predominantly replaced by electricity-based solutions. This influences the business models of electricity and especially gas distribution network operators (DNOs), where grid charges tend to rise. The resulting feedback effect could accelerate the decrease of demand and finally lead to the defection of the gas grid—an effect that has been neglected in energy system analysis so far. We present a multi-agent simulation with a rule-based gas and electricity DNO model and a building retrofit optimization model to analyze these interdependencies during the transformation path, focusing on the role of different technical, economic, and regulatory triggers. Our case studies for a real grid area of a German city shows that an interplay of the gas and electricity DNO’s strategy, as well as the building-, heating system-, grid-, and trigger-configuration, determine the decision on the extension, continuation, or defection of the gas grid infrastructure. Finally, strategies for how to reduce the risk of a gas grid defection, which are relevant for DNOs, policy makers, and creators of macro-economic models, are discussed.

Abstract:
Two experiments were conducted to examine eating preference of beef cattle for diets with or without the investigative enteric methane inhibitor 3-nitrooxypropanol (3-NOP). Nine beef steers were housed in individual stalls, each equipped with two feed bunks. The first experiment (Exp. 1) was conducted with a high forage diet and each animal received a diet without 3-NOP (CON) in one bunk and a diet with 3-NOP (dNOP) in the other bunk. The second study (Exp. 2) was conducted with the same animals about 6 months after Exp. 1 where a high grain diet without (CON) or with 3-NOP (dNOP) was offered. In Exp. 1, animals initially preferred CON compared with dNOP. Feed consumption from 0 to 3, 3 to 6, and 6 to 12 h after feeding was lower for dNOP compared with CON. However, dry matter intake (DMI) and feed consumption of dNOP gradually increased during Exp. 1 such that there was no preference between CON and dNOP on day 7. In Exp. 2, there was no preference for or against dNOP. Average DMI was greater for dNOP vs. CON, but interactions between diet and day for DMI and feed consumption rates indicated that daily preference between CON and dNOP was variable. In conclusion, beef steers initially detected a difference between CON and dNOP and selected in favor of CON rather than dNOP when they had not previously been exposed to 3-NOP. However, the animals rapidly acclimatized to a diet with 3-NOP (Exp. 1) and showed no eating preference between CON and dNOP within 7 days. This lack of preference was maintained throughout Exp. 2 when the same animals were fed a high grain diet.

Abstract:
The purpose of the investigation was to study the influence of nitrophenol pesticide (DNOC) on nitrogen metabolism measured by growth reduction in the presence of low doses of DNOC. It was established that DNOC (5; 10 mcg/ml) increased the uptake of nitrates from the culture medium which was connected with an increase of the total content of low molecular weight nitrogen compounds and the amine fraction. In the presence of DNOC the quality and quantity of free amino acids was changed On the other hand low concentrations of DNOC decreased the amount of high molecular weight compounds of nitrogen in the mycelium.

Abstract:
Dissolved Natural Organic Matter (DNOM) is a heterogeneous mixture of partly degraded, oxidised and resynthesised organic compounds of terrestrial or aquatic origin. In the boreal biome, it plays a central role in element cycling and practically all biogeochemical processes governing the physico-chemistry of surface waters. Because it plays a central role in multiple aquatic processes, especially microbial respiration, an improved understanding of the biodegradability of the DNOM in surface water is needed. Here the current study, we used a relatively cheap and non-laborious analytical method to determine the biodegradability of DNOM, based on the rate and the time lapse at which it is decomposed. This was achieved by monitoring the rate of oxygen consumption during incubation with addition of nutrients. A synoptic method study, using a set of lake water samples from southeast Norway, showed that the maximum respiration rate (RR) and the normalised RR (respiration rate per unit of carbon) of the DNOM in the lakes varied significantly. This RR is conceived as a proxy for the biodegradability of the DNOM. The sUVa of the DNOM and the C:N ratio were the main predictors of the RR. This implies that the biodegradability of DNOM in these predominantly oligotrophic and dystrophic lake waters was mainly governed by their molecular size and aromaticity, in addition to its C:N ratio in the same manner as found for soil organic matter. The normalised RR (independently of the overall concentration of DOC) was predicted by the molecular weight and by the origin of the organic matter. The duration of the first phase of rapid biodegradation of the DNOM (BdgT) was found to be higher in lakes with a mixture of autochthonous and allochthonous DNOM, in addition to the amount of biodegradable DNOM.

Abstract:
Signaling by nitric oxide (NO) and guanosine 3′,5′-cyclic monophosphate (cGMP) modulates fluid transport in Drosophila melanogaster. Expression of an inducible transgene encoding Drosophila NO synthase ( dNOS) increases both NOS activity in Malpighian (renal) tubules and DNOS protein in both type I (principal) and type II (stellate) cells. However, cGMP content is increased only in principal cells. DNOS overexpression results in elevated basal rates of fluid transport in the presence of the phosphodiesterase (PDE) inhibitor, Zaprinast. Direct assay of tubule cGMP-hydrolyzing phosphodiesterase (cG-PDE) activity in wild-type and dNOS transgenic lines shows that cG-PDE activity is Zaprinast sensitive and is elevated upon dNOS induction. Zaprinast treatment increases cGMP content in tubules, particularly at the apical regions of principal cells, suggesting localization of Zaprinast-sensitive cG-PDE to these areas. Potential cross talk between activated NO/cGMP and calcium signaling was assessed in vivo with a targeted aequorin transgene. Activated DNOS signaling alone does not modify either neuropeptide (CAP2b)- or cGMP-induced increases in cytosolic calcium levels. However, in the presence of Zaprinast, both CAP2b-and cGMP-stimulated calcium levels are potentiated upon DNOS overexpression. Use of the calcium channel blocker, verapamil, abolishes the Zaprinast-induced transport phenotype in dNOS-overexpressing tubules. Molecular genetic intervention in the NO/cGMP signaling pathway has uncovered a pivotal role for cell-specific cG-PDE in regulating the poise of the fluid transporting Malpighian tubule via direct effects on intracellular cGMP concentration and localization and via interactions with calcium signaling mechanisms.

Abstract:
Abstract Introduction: Sickle cell disease (SCD) men display priapism. Previous studies showed that endothelial nitric oxide synthase (eNOS) gene-deficient mice and combined eNOS and neuronal nitric oxide synthase double gene-deficient mice (dNOS-/-) display a priapism phenotype associated with phosphodiesterase-5 (PDE5) downregulation. The Berkeley SCD transgenic mice display features of priapism, and, as in SCD human, this appears to be due to decreased nitric oxide (NO) signaling, which leads to lower PDE5 in the penis. Thus, when an erectile stimulus occurs in vivo, cGMP accumulates into the cavernosal smooth muscle cells, rendering the penile vasculature uncontrollably dilated, penile erection persists (i.e. priapism) as cGMP is not degraded as a consequence of PDE5 downregulation. Moreover, oxidative/nitrosative stress have been associated with priapism in SCD mice. In this study, since decreased NO bioavailability leads to lower PDE5 in penis, we aimed to evaluate the effects of new NO donor, a hybrid derived from thalidomide and hydroxycarbamide, 3-(1,3-dioxoisoindolin-2-yl)benzyl nitrate (4C), on functional and molecular alterations of erectile function in SCD and dNOS-/- mice. We have focused on the dysregulated NO-cGMP-PDE5 pathway and oxidative/nitrosative stress in erectile tissue of SCD and dNOS-/-mice. Methods: Wild type (WT, C57BL/6), Berkeley SCD transgenic and dNOS-/-male mice (3-5 mo old) were treated with compound 4C (100 µmol/kg/day) or its vehicle (20% Cremophor) daily for 3 weeks via intraperitoneal injection. The intracavernous pressure (ICP) was assessed following electrical stimulation of cavernous nerve (CN) in anaesthetized mice. ICP were normalized per mean arterial pressure (MAP). In separate protocols, corpus cavernosum (CC) strips were mounted in isolated organ baths, and the relaxing responses to acetylcholine (ACh; endothelium-dependent response) and sodium nitroprusside (SNP; endothelium-independent response), as well as electrical-field stimulation (EFS; nitrergic relaxation) were obtained in CC strips precontracted with the α1-adrenergic receptor agonist phenylephrine (10 µM). Results: The CN stimulation (4 V) caused increases of ICP/MAP ratio in WT, SCD and dNOS-/- mice. However, half detumescence time (sec) and poststimulated ICP/MAP ratio values after 9 min were (P<0.05) higher in SCD compared to the WT group, indicating that SCD mice display priapism. In dNOS-/- group, maximal ICP/MAP ratio values were higher (P<0.05) compared to WT mice, indicating that dNOS-/- mice also display priapism. Compound 4C treatment reversed the priapism in SCD and dNOS-/- mice. The cumulative addition of ACh (0.001-10 µM) produced concentration-dependent CC relaxations in WT and SCD groups, but the ACh potency (pEC50) value was higher (P<0.05) in CC of SCD compared to WT mice, which was reversed by 4C. Likewise, the nitrergic relaxation induced by EFS was also higher (P<0.05) in SCD mice compared to control mice (2 Hz: 12 ± 3 and 37 ± 9 %, respectively; n=5), which was reversed by 4C treatment. Similarly, SNP (0.01- 10 µM) produced concentration-dependent CC relaxations in WT, SCD and dNOS-/- groups, but, again, the maximal relaxations elicited by this agent were higher (P<0.05) in SCD (93 ± 7%) and dNOS-/- (105 ± 1%) groups compared to WT mice (72 ± 4%), which were fully restored to WT values with compound 4C treatment (n=5-9). PDE5 protein expressions were reduced (P<0.05) by approximately 48% and 35% in penile tissues from SCD and dNOS-/- compared to the WT group, respectively. Compound 4C treatment restored (P<0.05) the protein levels of PDE5 in the penises from SCD and dNOS-/- group. The protein expressions for gp91phox and 3-NT were significantly higher (P<0.05) in erectile tissues from SCD and dNOS-/- compared to the WT group, which were reduced (P<0.05) by 4C treatment (n=5-9). In WT mice, PDE5, gp91phox and 3-NT protein expressions were not affected by 4C, as well as CC relaxations induced by ACh, SNP and EFS. Conclusion: Compound 4C treatment reversed the priapism, as well as enhanced NO-mediated CC relaxations and normalized PDE5 expressions in the penises from SCD and dNOS-/- mice. Moreover, increased gp91phox and 3-nitrotyrosine protein expressions were also decreased by 4C in SCD and dNOS-/-mice. Compound 4C may constitute an additional strategy to prevent priapism in SCD, since SCD-related priapism therapies are few.

Abstract:
ABSTRACT Temperature sensitivity of DNA polymerization and growth of a dnaX(Ts) mutant is suppressible at 39 to 40°C by mutations in the initiator gene, dnaA. These suppressor mutations concomitantly cause initiation inhibition at 20°C and have been designated Cs,Sx to indicate both phenotypic characteristics of cold-sensitive initiation and suppression of dnaX(Ts). One dnaA(Cs,Sx) mutant, A213D, has reduced affinity for ATP, and two mutants, R432L and T435K, have eliminated detectable DnaA box binding in vitro. Two models have explained dnaA(Cs,Sx) suppression of dnaX, which codes for both the τ and γ subunits of DNA polymerase III. The initiation deficiency model assumes that reducing initiation efficiency allows survival of the dnaX(Ts) mutant at the somewhat intermediate temperature of 39 to 40°C by reducing chromosome content per cell, thus allowing partially active DNA polymerase III to complete replication of enough chromosomes for the organism to survive. The stabilization model is based on the idea that DnaA interacts, directly or indirectly, with polymerization factors during replication. We present five lines of evidence consistent with the initiation deficiency model. First, a dnaA(Cs,Sx) mutation reduced initiation frequency and chromosome content (measured by flow cytometry) and origin/terminus ratios (measured by real-time PCR) in both wild-type and dnaX(Ts) strains growing at 39 and 34°C. These effects were shown to result specifically from the Cs,Sx mutations, because the dnaX(Ts) mutant is not defective in initiation. Second, reduction of the number of origins and chromosome content per cell was common to all three known suppressor mutations. Third, growing the dnaA(Cs,Sx) dnaX(Ts) strain on glycerol-containing medium reduced its chromosome content to one per cell and eliminated suppression at 39°C, as would be expected if the combination of poor carbon source, the Cs,Sx mutation, the Ts mutation, and the 39°C incubation reduced replication to the point that growth (and, therefore, suppression) was not possible. However, suppression was possible on glycerol medium at 38°C. Fourth, the dnaX(Ts) mutation can be suppressed also by introduction of oriC mutations, which reduced initiation efficiency and chromosome number per cell, and the degree of suppression was proportional to the level of initiation defect. Fifth, introducing a dnaA(Cos) allele, which causes overinitiation, into the dnaX(Ts) mutant exacerbated its temperature sensitivity.

Abstract:
The present research has as objective accomplishes a study of the environmental impact provoked by the anthropic progress on the native vegetation, in order to identify the permanent preservation areas (PPA) like hillsides of hills, ciliary's forests and ofter subsidies for its preservation.The more intense man's intervention in the environment through the natural resources, especially forests, rivers and areas of permanent preservation are a consequence of the technological progress and the population growth that we have been verifying along the time. These natural resources for turning more and more important to the human being besides the destruction of yours forests, will do in a elose future, with that the treatment of the water has a high price too much for many. For better understanding of the research, it was elaborated thematic maps as: Geomorfologic, Hydrologic, Hipsometric, Downward slope, Use of the earth x steepness <5% and >47% in two periods, 1995 and 2003, with the purpose to know the space and environmental transformations in this interval of time and to propose solutions of softening the found environmental impacts. Parallel through interview it was verified vary irregularities as: I spill of garbage in the margins of rivers and along highways, sewer spilled to open sky and deforestation, irregular occupations forming small slums. In the rising economical partner it was detected that 31% of the garbage are collected twice a week and 66% only once a week. The ones that deposit the garbage to open sky add 62% and the one that burn add 28%. About the sewers, 25% spill it at open sky without any treatment or channeled towards the rivers, of these interviewees 45% produce some type of environmental impact. Of the homes of the catchment 87% they possess property registration, 13% are invaded lots, and ali of them are in the Cechela's hillside.
A presente pesquisa tem como objetivo realizar um estudo do impacto ambiental provocado pelo avanço antrópica na vegetação nativa, a fim de identificar áreas de preservação permanente (APP) como encostas de morros, matas ciliares e oferecer subsídios para sua preservação. A intervenção do homem cada vez mais intensa no meio ambiente através dos recursos naturais, em especial florestas, rios e áreas de preservação permanente é uma conseqüência do progresso tecnológico e do crescimento populacional que se tem verificado ao longo do tempo, num futuro próximo, estes recursos naturais por se tornar cada vez mais importantes para o ser humano além da destruição de nossas florestas, fará com que o tratamento da água tenha um preço elevado demais para muitos. Para melhor entendimento da pesquisa foram elaborados mapas temáticos como: Geomorfológico, Hidrológico, Hipsométrico, Clinográfico, Uso da terra x declividade < 5% e < 47% em dois períodos, 1995 e 2003, com a finalidade conhecer as transformações espaciais e ambientais neste intervalo de tempo e propor soluções de amenizar os impactos ambientais encontrados. Paralelamente através de entrevista foram constatados varias irregularidades como: despejo de lixo nas margens de rios e ao longo de estradas, esgoto despejado a céu aberto e desmatamento, ocupações irregulares formando pequenas favelas. No levantamento sócio econômico foi detectado que 31% do lixo é recolhido duas vezes por semana e 66% somente uma vez por semana. Os que depositam o lixo a céu aberto somam 62% e os que queimam somam 28%. Os esgotos 25% despejam á céu aberto sem nenhum tratamento ou canalizado em direção aos rios, destes entrevistados 45% produzem algum tipo de impacto ambiental. Das moradias da sub-bacia hidrográfica 87% possuem registro de propriedade, 13% são lotes invadidos, todos eles são na encosta do morro do Cechela.

Abstract:
The work presented in this thesis belongs to the domain of theoretical and experimental gas phase molecular spectroscopy. It consists of two parts dedicated to two relatively different aspects in this field. The first part presents a high resolution analysis of the ν5 fundamental band (NO2 in plane bending mode) positions and intensities of D14NO3 (deuterated nitric acid) in the 11 µm spectral region. For this study, we used an infrared spectrum of D14NO3 recorded in the 700−1400 cm−1 region on a Fourier transform spectrometer at Bergische Universität in Wuppertal (Germany). Our analysis demonstrates that the fundamental ν5 band centered at 887.657 cm−1 is strongly perturbed. Indeed, it proves that 5^1 and 7^1+9^1 energy levels of DNO3 are coupled through A and B type Coriolis resonances. The resonance scheme for the isotopologue D14NO3 therefore differs substantially from the schemes of H14NO3 and H15NO3 that feature dominantly Fermi type resonances. The second theme treated in this work is devoted to the lineshapes of pure rotational transitions of CH3F with the study of collisional broadening (collisions CH3F-CH3F and CH3F-He) of optical transitions and their Stark components. The microwave measurements were realised at ICT in Prague. Their analysis enabled to provide collisional parameters using various line profiles (Voigt, Rautian, Speed dependent) for the J, K → J + 1, K (K = 0, ..., J) transitions with J = 1 and J = 3 as well as for their various Stark components J, K, M → J + 1, K, M' (|M| = 0, ..., J ; |M − M'| = 0, 1). Moreover, a correct use of model based on Infinite Order Sudden approximation led to very satisfactory results of the observed line-mixing effects. The retrieved experimental results complete and extend the previous studies and provide the first successful demonstration of the ability of the IOS approximation to model line-mixing effects among Stark transitions

This study investigated the actions of two dicarboxylic compounds, the first had cyclic framework and rigid structure, and the other had an acyclic framework and flexible structure, on the glutamatergic neurotransmission, oxidative damage and behavior in mice. The first compound evaluated was D,L-cis-2,3-pyrrolidine dicarboxylate (D,L-cis-2,3-PDC), a new glutamate analogue. D,L-cis-2,3-PDC reduced sodium-independent [3H]-L-glutamate binding by 50% in lysed membrane preparations and had no effect on sodium-dependent glutamate binding. Intracerebroventricular administration (ICV) of D,L-cis-2,3-PDC (7.5 - 25 nmol/ 5μl) induced dose-dependent tonic-clonic convulsions. The co-administration of MK-801 (7 nmol/ 2.5 μl; ICV), a noncompetitive NMDA receptor antagonist, with D,L-cis-2,3-PDC (16.5 nmol/ 2.5 μl; ICV) fully protected the animals against D,L-cis-2,3-PDC-induced convulsions, while the co-administration of DNQX (10 nmol/ 2.5 μl; ICV), a AMPA and KA receptors antagonist, increased the latency to convulsion and did not alter the percentage of animals that had convulsions. These results suggest that D,L-cis-2,3-PDC-induced effects are mediated predominantly by NMDA receptors activation. The second compound studied was succinate, the accumulating substrate in succinate dehydrogenase (SDH) deficiencies and SDH inhibitor intoxication. Adult male mice received an ICV injection of succinate (0.7, 1.0 and 1.7 μmol/ 5 μl) or 0.9% NaCl (5 μl) and had their exploratory behavior assessed in an open field for 10 min. Succinate (0.7 and 1.0 μmol/ 5 μl) decreased locomotor activity behavior and increased thiobarbituric acid reactive substances (TBARS) and protein carbonylation in the forebrain. Conversely, 1.7 μmol of succinate did not alter locomotor activity or oxidative damage parameters. The involvement of NMDA receptors in the succinate-induced increase of total protein carbonylation content and exploratory behavior inhibition was assessed by co-administrating MK-801 (7 nmol/ 2.5 μl, ICV) with succinate (1 μmol/ 2.5 μl, ICV). The co-administration of MK-801 protected against succinate-induced increase of total protein carbonylation and decrease of locomotor activity. These results suggest the involvement of NMDA receptors in these effects of succinate, which may of particular relevance for succinate-accumulating conditions, such as SDH inhibitors intoxication and inherited SDH deficiencies.
Os receptores glutamatérgicos são alvos da ação de muitas neurotoxinas análogas ao L-glutamato. Neste estudo foram investigadas as ações de dois compostos dicarboxílicos, um de cadeia cíclica e estrutura rígida e o outro de cadeia acíclica e estrutura flexível, sobre a neurotransmissão glutamatérgica, dano oxidativo e comportamento em roedores. No primeiro trabalho foi investigado se o D,L-cis-2,3-dicarboxilato de pirrolidina (D,L-cis-2,3-PDC) altera a ligação de [3H]-L-glutamato em membranas plasmáticas de córtex de ratos adultos e se os receptores N-metil-D-aspartato (NMDA) estão envolvidos nas convulsões induzidas por este composto. O D,L-cis-2,3-PDC reduziu a ligação de [3H]-L-glutamato Na+-independente em 50% nas preparações de membranas rompidas e não apresentou efeito sobre a ligação de [3H]-L-glutamato Na+-dependente. A administração intracerebroventricular (ICV) de D,L-cis-2,3-PDC (7,5; 25 nmol/ 5 μl) induziu convulsões generalizadas do tipo tônico-clônica nos camundongos, de uma maneira dose-dependente. A co-administração de MK-801 (7 nmol/ 2,5 μl; ICV), um antagonista não-competitivo dos receptores NMDA, com D,L-cis-2,3-PDC (16,5 nmol/ 2,5 μl; ICV), protegeu totalmente os animais das convulsões induzidas por D,L-cis-2,3-PDC, enquanto que a co-administração de DNQX (10 nmol/ 2,5 μl; ICV), um antagonista dos receptores AMPA e KA, aumentou a latência das convulsões, mas não alterou a percentagem de animais que tiveram convulsões. Estes resultados sugerem que os efeitos induzidos por D,L-cis-2,3-PDC são mediados principalmente pela ativação dos receptores NMDA. No segundo estudo, foi investigado se o sucinato, substrato que se acumula nas deficiências da enzima sucinato desidrogenase (SDH) e nas intoxicações por inibidores da SDH, causa lipoperoxidação e carbonilação protéica, e se os receptores NMDA estão envolvidos no dano oxidativo induzido por sucinato. Camundongos machos adultos receberam uma injeção ICV de sucinato (0,7; 1,0; 1,7 μmol/ 5 μl) ou 0,9 % de NaCl (5 μl) e seu comportamento foi analisado em um campo aberto por 10 minutos. Sucinato (0,7; 1,0 μmol/ 5 μl) diminuiu a atividade locomotora e aumentou as substâncias que reagem ao ácido tiobarbitúrico (TBARS) e carbonilação protéica no cérebro. Por outro lado, 1,7 μmol de sucinato não alterou a atividade locomotora ou os parâmetros de dano oxidativo. O envolvimento dos receptores NMDA no aumento induzido por sucinato do conteúdo de carbonilação protéica e da inibição do comportamento exploratório foi avaliado pela co-administração de MK-801 (7nmol/ 2,5 μl, ICV) com sucinato (1 μmol/ 2,5 μl, ICV). A co-administração de MK801 protegeu contra o aumento induzido por sucinato da carbonilação protéica e na diminuição da atividade locomotora. Esses resultados sugerem o envolvimento dos receptores NMDA nesses efeitos do sucinato, os quais são de grande relevância nas condições em que acumula sucinato, tais como as intoxicações com inibidores da SDH e deficiências dessa enzima causadas por erros inatos do metabolismo.

Abstract:
In the literature, there are several methodologies to estimate technical losses in electrical distribution networks. The range of techniques is broad, ranging from basic techniques (based on loss factor, for example) to sophisticated ones (based on artificial intelligence). These methodologies are important, because the costs of technical losses represent a huge part of the total operation costs of distribution network operators (DNOs). However, the presence of clandestine connections, common in developing countries, was not considered in the methodologies encountered in the literature. Clandestine connections occur when a consumer has made his/her connection without DNO permission. In these cases, the amount of energy consumed by a clandestine "consumer" is a nontechnical loss (and, therefore, should be correctly computed as nonbilled energy). Therefore, a new methodology is proposed to consider the presence of clandestine connections in energy loss estimation in distribution systems.

Methods for simultaneous determination of 29 legacy and insensitive munition (IM) constituents in aqueous, soil-sediment, and tissue matrices by high-performance liquid chromatography (HPLC).

Abstract:
Standard methods are in place for analysis of 17 legacy munitions compounds and one surrogate in water and soil matrices; however, several insensitive munition (IM) and degradation products are not part of these analytical procedures. This lack could lead to inaccurate determinations of munitions in environmental samples by either not measuring for IM compounds or using methods not designed for IM and other legacy compounds. This work seeks to continue expanding the list of target analytes currently included in the US Environmental Protection Agency (EPA) Method 8330B. This technical report presents three methods capable of detecting 29 legacy, IM, and degradation products in a single High Performance Liquid Chromatography (HPLC) method with either ultraviolet (UV)-visible absorbance detection or mass spectrometric detection. Procedures were developed from previously published works and include the addition of hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine (MNX); hexahydro-1,3-dinitroso-5-nitro-1,3,5-triazine (DNX); hexahydro-1,3,5-trinitroso-1,3,5-triazine (TNX); 2,4-diamino-6-nitrotoluene (2,4-DANT); and 2,6-diamino-4-nitrotoluene (2,6-DANT). One primary analytical method and two secondary (confirmation) methods were developed capable of detecting 29 analytes and two surrogates. Methods for high water concentrations (direct injection), low-level water concentrations (solid phase extraction), soil (solvent extraction), and tissue (solvent extraction) were tested for analyte recovery of the new compounds.
