The spectral properties of the K3La(PO4)2:Eu3+ nanophosphors synthesized by the combustion method are reported. The phosphors were characterized by X-ray diffraction, transmission electron microscopy, and optical spectroscopy. The XRD pattern reveals a pure monoclinic phase of the K3La(PO4)2 with the average particle size of 30 nm in diameter. Under UV excitation, the phosphors exhibited several emission bands which were assigned to 4f-4f transitions of Eu3+ ions. The red shade of the Eu3+ ion with the CIE coordinates (x, y) as (0.63, 0.37) suggests that this material is a promising phosphor for near-UV InGaN-based LED lighting.

Through employing the fluid ignition technique, we created the samples CaSr2(PO4)2:Eu3+ with Eu3+ incorporated then assessed them in the form of contactless optical heat measurement as well as solid-state illumination. We identified the attributes for these samples including X-ray diffraction (XRD), photoluminescent spectroscopy, Fourier transmute infrared spectroscopy (FTIS) along with photoluminescent spectroscopy correlating with temperature. XRD, along with FTIS, validates that the one-stage samples were formed via the orthophosphate anion (PO4)3- . In the case of these samples, nUV recreation under 395 nm generated potent, orange-red discharge lines under 592 nm as well as 615 nm, which is consistent with the standard shifts between 5D0 and 7F1 as well as 5D0 and 7F2 for the Eu3+ ions. The International Commission on Illumination (CIE) coordinates (0.65, 0.35) based on the hue scale validate the red discharge. For the task of attaining optical heat measurement, we took advantage of the fluorescent intenseness proportion technique that utilizes heat-incorporated discharge states of 5D1 as well as 5D0 for Eu3+ . The samples have maximum responsiveness reaching roughly 0.0023 K-1 under 323 K or small heat levels. According to the outcomes, it is possible to utilize the samples when it comes to contactless optical heat measurement as well as solid-state illumination.

An anhydrous orthophosphate, K3Eu5(PO4)6 (tripotassium pentaeuropium hexaphosphate), has been prepared by a high-temperature solid-state reaction combined with hydrothermal synthesis, and its crystal structure was determined by single-crystal X-ray diffraction analysis (SC-XRD). The results show that the compound crystallizes in the monoclinic space group C2/c and the structure features a three-dimensional framework of [Eu5(PO4)6]∞, with the tunnel filled by K+ ions. The IR spectrum, UV–Vis spectrum and luminescence properties of polycrystalline samples of K3Eu5(PO4)6, annealed at temperatures of 650, 700, 750, 800 and 850 °C, were investigated. Although with a full Eu3+ concentration (9.96 × 1021 ions cm−3), the self-activated phosphor K3Eu5(PO4)6 shows s strong luminescence emission intensity with a quantum yield of 37%. Under near-UV light excitation (393 nm), the series of samples shows the characteristic emissions of Eu3+ ions in the visible region from 575 to 715 nm. The sample sintered at 800 °C gives the strongest emission and its lifetime sintered at 800 °C (1.88 ms) is also the longest of all.

De l'urée et du super phosphate triple ont été appliqués aux étangs d'alevinage de carpes chinoises de la station Deroua pour stimuler la croissance des algues. Toutefois, une forte proportion de ce phosphore est fixée par les sédiments et sera libérée en grande quantité dans les étangs lorsque les sédiments sont en conditions anaérobies. Nous avons étudié le relargage des orthophosphates par les sédiments provenant de deux étangs différents. L'un (A1) en terre ce qui permet la percolation des éléments nutritifs vers les couches profondes, l'autre (C1) dont le fond recouvert d'une fine membrane en polyéthylène, est parfaitement imperméable et empêche toute perte. Par ailleurs, nous avons étudié les effets de l'oxygène dissous, du pH, des nitrates et du glucose sur le relargage des orthophosphates par les sédiments. Les résultats obtenus montrent qu'en anaérobiose, la solubilité du phosphore augmente dans l'eau interstitielle. Les orthophosphates libérés, dont la concentration peut atteindre 873 µg/l, proviennent de la fraction minérale en particulier du Fe(OOH)=P. Le sédiment C1 qui accumule de grandes quantités de matière organique libère plus de phosphore que le sédiment A1. L'addition des nitrates limite la mobilisation du phosphore à partir des sédiments. Le pH acide provoque la dissolution du phosphore lié au calcium alors qu'un pH alcalin provoque celle du phosphore lié aux hydroxydes de fer et sa précipitation partielle sur les carbonates présents dans les sédiments.

The application of organic fertiliser is a commonly used method to improve the utilisation efficiency of phosphorus (P) fertiliser. However, long-term over-fertilisation will cause environmental pollution. This study analysed a field test was conducted to study the impacts of P forms in soil under long-term (40 years) rotation fertilisation, to evaluate the contribution of different fertilisation to the available P form, to clarify how to apply pig manure to improve the concentration of available P forms. The results show that the main P compounds were orthophosphate and phosphate monoester. The combination of a high amount of manure and NPK fertilisers can increase the content of orthophosphate that can be absorbed and utilised by crops, the orthophosphate was 477.2 mg/kg, and phosphate monoester was 190.4 mg/kg. The long-term addition of nitrogen fertiliser significantly reduced the pH value of soil, and the addition of manure slowed down the trend of pH reduction. Furthermore, manure in combination with NPK fertiliser, can extremely increase the total P extracted by NaOH-EDTA by changing soil pH. The NaHCO<sub>3</sub>-soluble P (Ca<sub>2</sub>-P), NH<sub>4</sub>Ac-soluble P (Ca<sub>8</sub>-P), NH<sub>4</sub>F-soluble P (Al-P), and occluded-P (O-P) were positively correlated with orthophosphate, while middle stable and high stable organic P was positively correlated with monophosphate.

Les échanges de phosphore à l'interface eau-sédiment ont été étudiés dans la retenue Al Massira. La campagne de prélèvements a été menée pendant la faible oxygénation des eaux profondes au mois d'octobre 1991. Les mesures des échanges de phosphore ont été réalisées in situ en chambre benthique. Les valeurs de pH sont élevées et reflètent clairement l'influence de la nature géologique du bassin versant sur la composition chimique des eaux. Ce bassin versant, formé essentiellement de roches sédimentaires calcaires, est vraisemblablement à l'origine des concentrations élevées en calcium mesurées dans les chambres benthiques. En période de faible oxygénation, on note une augmentation des teneurs en phosphore particulaire dans les eaux surnageantes en raison de la présence de complexes calcium-phosphore, fer-phosphore et manganèse-phosphore. En période d'anoxie, la réduction de ces complexes est accompagnée d'une aug- mentation des teneurs en phosphore. La densité bactérienne et la concentration en phosphore total et notamment en orthophosphates suivent une évolution temporelle comparable. Une fraction non négligeable du phosphore particulaire serait liée aux bactéries. Des mesures drastiques de déphosphatation du tributaire Oum Errbia doivent être prises pour éviter la dissociation des complexes Ca, Fe, Mn-Phosphore et le relargage de phosphore biodisponible.

L'activité de la phosphatase alcaline (APA) bactérienne et phytoplanctonique a été mesurée bimensuellement du mois de mars au mois de décembre 1998 au sein d'un réservoir mésotrophe situé dans une zone à climat semi-aride (Allal El Fassi, Maroc). Les résultats montrent que l'APA totale est importante (0,107-1,780 mmol PNP·l-1·h-1) et majoritairement d'origine bactérienne (> 60 %) au niveau de l'épilimnion, alors qu'elle est à dominance algale (> 58 %) dans le méta- et l'hypolimnion. L'absence de corrélation entre l'APA totale et les concentrations en orthophosphates suggère que l'hydrolyse par cette enzyme n'est pas significative dans le processus de régénération du phosphore dans ce réservoir. Par conséquent, l'APA ne pourrait pas être un indicateur fiable du déficit en phosphore dans le milieu.

Les variations temporelles des concentrations en phosphore, celles des abondances bactériennes et de l'activité de la phosphatase alcaline (APA) ont été estimées in situ en chambre benthique placée en deux points du réservoir Sahela (Maroc) durant les mois de septembre et octobre 98. En période de faible oxygénation, nous avons enregistré des élévations relativement faibles des concentrations en orthophosphates (de 0,020 à 0,035 mg. l-1 au point 1 et 0,015 à 0,025 mg. l-1 au point 2) par rapport au phosphore total (0,080 à 0,100 mg. l-1 au point 1 et de 0,035 à 0,040 mg. l-1 au point 2). À cette période, les abondances bactériennes et l'APA montrent des valeurs maximales (8. 106 bact. ml-1 et 0,323 mmol.PNP l-1.h-1 au point 1 et 6.106 bact. ml-1 et 0,438 mmol.PNP l-1.h-1 au point 2 respectivement). L'apparition des conditions anoxiques et la diminution du pH favorisaient la dissolution du phosphore particulaire et la libération du phosphore réactif soluble. Cette libération s'accompagne d'une élévation des abondances de bactéries anaérobies (de 5.106 à 9,2. 106 bact. ml-1 au point 1 et de 3,8.106 à 7,2. 106 bact. ml-1 au point 2) et une diminution progressive d'APA (de 0,200 à 0,025 mmol.PNP l-1.h-1 au point 1 et de 0,125 à 0,077 mmol.PNP l-1.h-1 au point 2). Ce relargage du phosphore à partir du sédiment est accentué par les rejets domestiques et industriels de la ville de Taounate, ce qui accélère le processus d'eutrophisation de ce réservoir.

In this work, LaPO4:Ce, Tb phosphors were prepared by firing a LaPO4:Ce, Tb precipitate using an ionic-liquid-driven supported liquid membrane system. The entire system consisted of three parts: a mixed rare earth ion supply phase, a phosphate supply phase, and an ionic-liquid-driven supporting liquid membrane phase. This method showed the advantages of a high flux, high efficiency, and more controllable reaction process. The release rate of PO43− from the liquid film under different types of ionic liquid, the ratio of the rare earth ions in the precursor mixture, and the structure, morphology, and photoluminescence properties of LaPO4:Ce, Tb were investigated by inductively coupled plasma-atomic emission spectroscopy, X-ray diffraction, Raman spectra, scanning electron microscopy, and photoluminescence emission spectra methods. The results showed that a pure phase of lanthanum orthophosphate with a monoclinic structure can be formed. Due to differences in the anions in the rare earth supply phase, the prepared phosphors showed micro-spherical (when using rare earth sulfate as the raw material) and nanoscale stone-shape (when using rare earth nitrate as the raw material) morphologies. Moreover, the phosphors prepared by this method had good luminescent properties, reaching a maximum emission intensity under 277 nm excitation with a predominant green emission at 543 nm which corresponded to the 5D4-7F5 transition of Tb3+.

Phosphorus (P) stratification in no-tillage (NT) systems has important implications for crop growth and potential P loss, but little is known about P forms and their distribution when mineral P fertilizers are placed to the depth of 5 cm in NT soil. A 10-year field experiment was used to study the effect of NT and mouldboard plough (MP) on soil P forms at three depths (0–5, 5–10 and 10–20 cm) and their relationship with Fe and Al oxides. The results indicated that stratification of organic P forms occurred under NT treatment, and Fe oxides may have a stronger capacity for adsorbing the P forms. When mineral P fertilizers were placed to the depth of 5 cm under NT treatment, there was no significant difference in P forms or crop yield between NT and MP treatment, and orthophosphate did not show any significant difference under NT treatment between 0–5 cm and 5–10 cm depth. Overall, the agricultural management practice that mineral P fertilizers are placed to the depth of 5 cm under NT treatment could result in stratification of P forms, while the changes in the distribution of P forms in soil profiles might help reduce potential P loss in surface runoff and do not make any difference to crop growth.

Ce travail concerne l'étude de la qualité physico-chimique de la masse d'eau du réservoir Daourat au Maroc ; situé sur le cours inférieur du bassin Oum Rbia. Une vidange du réservoir a lieu le 23 décembre 2001, l'impact de cette vidange sur la qualité physico-chimique de l'eau a été déduit à travers l'augmentation du débit à l'entrée et à la sortie du réservoir en décembre ; l'élévation du taux de la matière en suspension ; des concentrations en éléments nutritifs et de la chlorophylle " a ". Cette étude inclue également une analyse de régression qui a permis de déterminer une relation entre le phosphore et la chlorophylle " a " ; ainsi qu'une évaluation du niveau d'eutrophisation du réservoir Daourat. Les résultats fournis par les paramètres physico-chimiques ont révélé que la masse d'eau ne présente aucune stratification thermique ni anoxie et que le pH est alcalin. L'évolution des concentrations en éléments nutritifs dans la masse d'eau du réservoir dépend des apports exogènes et endogènes. Les apports exogènes sont dominés par les apports latéraux venant du bassin versant local peu boisé et caractérisé par un sol à vocation agricole responsable de l'enrichissement du milieu récepteur en éléments azotés. Les apports endogènes sont gouvernés par les interactions eau - sédiment suite à la minéralisation de la matière organique en période estivale et par le relargage d'éléments à partir du sédiment suite à la vidange et à la crue en période hivernale. L'impact de la vidange sur l'écosystème étudié a été déduit à partir des modifications des paramètres abiotiques et biotique enregistrés en décembre (période de vidange) dans le milieu du réservoir (S2) et son aval (S3).

Transcription factor IIIA (TFIIIA), isolated from the cytoplasmic 7S ribonucleoprotein complex of Xenopus oocytes, is phosphorylated when incubated with [γ-32P]ATP. This modification is due to a trace kinase activity that remains associated with the factor through several steps of purification. The kinase can use either ATP or GTP, and will phosphorylate casein and phosvitin to the exclusion of TFIIIA. The kinase is reactive with a ten-amino-acid peptide that is a specific substrate for protein kinase CK2 (CK2; formerly casein kinase II). In addition, inhibition of phosphorylation by heparin and stimulation by spermidine indicate that the activity can be ascribed to CK2. Phospho amino acid analysis established that serine is the sole phosphoryl acceptor in TFIIIA. There are four consensus sites for CK2 in TFIIIA; all contain serine residues at the putative site of phosphorylation. TFIIIA immunoprecipitated from oocytes, which were incubated with [32P]orthophosphate, is also phosphorylated exclusively on serine residues. Only the cyanogen bromide fragment, which was derived from the N-terminal end of TFIIIA, is labelled in vivo. A recognition sequence for CK2, located at Ser16 in the β-turn of the first zinc-finger domain, is the only protein kinase consensus sequence present in this peptide. Assays in vitro with site-specific mutants of TFIIIA established that Ser16 is the preferred site of phosphorylation, with some secondary modification at Ser314.

Abstract. This paper reviews current knowledge on sampling, storage and analysis of phosphorus (P) in river waters. Potential sensitivity of rivers with different physical, chemical and biological characteristics (trophic status, turbidity, flow regime, matrix chemistry) is examined in terms of errors associated with sampling, sample preparation, storage, contamination, interference and analytical errors. Key issues identified include: The need to tailor analytical reagents and concentrations to take into account the characteristics of the sample matrix. The effects of matrix interference on the colorimetric analysis. The influence of variable rates of phospho-molybdenum blue colour formation. The differing responses of river waters to physical and chemical conditions of storage. The higher sensitivities of samples with low P concentrations to storage and analytical errors. Given high variability of river water characteristics in space and time, no single standardised methodology for sampling, storage and analysis of P in rivers can be offered. ‘Good Practice’ guidelines are suggested, which recommend that protocols for sampling, storage and analysis of river water for P is based on thorough site-specific method testing and assessment of P stability on storage. For wider sampling programmes at the regional/national scale where intensive site-specific method and stability testing are not feasible, ‘Precautionary Practice’ guidelines are suggested. The study highlights key areas requiring further investigation for improving methodological rigour. Keywords: phosphorus, orthophosphate, soluble reactive, particulate, colorimetry, stability, sensitivity, analytical error, storage, sampling, filtration, preservative, fractionation, digestion

Ornithine decarboxylase (ODC), the first enzyme in polyamine biosynthesis, is highly regulated by many trophic stimuli, and changes in its levels and organization correlate with cytoskeletal changes in normal human epidermal keratinocytes (NHEK). NHEK ODC exhibits a filamentous perinuclear/nuclear localization that becomes more diffuse under conditions that alter actin architecture. We have thus asked whether ODC colocalizes with a component of the NHEK cytoskeleton. Confocal immunofluorescence showed that ODC distribution in NHEK was primarily perinuclear; upon disruption of the actin cytoskeleton with cytochalasin D, ODC distribution was diffuse. The ODC distribution in untreated NHEK overlapped with that of keratin in the perinuclear but not cytoplasmic area; after treatment with cytochalasin D, overlap between staining for ODC and for keratin was extensive. No significant overlap with actin and minimal overlap with tubulin filament systems were observed. Subcellular fractionation by sequential homogenizations and centrifugations of NHEK lysates or detergent and salt extractions of NHEK in situ revealed that ODC protein and activity were detectable in both soluble and insoluble fractions, with mechanical disruption causing additional solubilization of ODC activity (three- to sevenfold above controls). Fractionation and ODC immunoprecipitation from [32P]orthophosphate-labeled NHEK lysates showed that a phosphorylated form of ODC was present in the insoluble fractions. Taken together, these data suggest that two pools of ODC exist in NHEK. The first is the previously described soluble pool, and the second is enriched in phospho-ODC and associated with insoluble cellular material that by immunohistochemistry appears to be organized in conjunction with the keratin cytoskeleton.

Chartins are a unique class of three families of microtubule-associated proteins, each consisting of several isoforms possessing varying degrees of phosphorylation. The most highly phosphorylated chartin isoforms are highly enriched in neuronal cell fractions containing microtubules and there is evidence that their phosphorylation may play a role in promoting neurite outgrowth. The present work describes the relationship between the phosphorylation state of chartins and the presence of intact microtubules in long-term cultures of NGF-treated, neurite-bearing PC12 cells. Cultures were depleted of microtubules by exposure to high concentrations of depolymerizing agents for 2-24 h. Radiolabeling of cellular proteins with [32P]orthophosphate or [35S]methionine revealed that both the ongoing and steady-state phosphorylation of chartins is markedly altered under these conditions. Two-dimensional isoelectric focusing by SDS-PAGE of whole cell extracts demonstrated that the more acidic, highly phosphorylated isoforms are diminished with a concomitant increase in the more basic, less phosphorylated isoforms. These phosphorylation changes were relatively specific for the chartins and were not observed for phosphorylated MAP 1.2, phospho-beta-tubulin, or most other phosphoproteins. Thus, the phosphorylation state of chartins, but not of other phosphoproteins, is regulated by the presence of native microtubules. Despite depolymerization of microtubules, neurites remained extended for at least 24 h. Neurite elongation, however, was arrested. Microtubules, therefore, may be required for extension, but not for short-term maintenance of well-established neurites. Taxol, which promotes tubule assembly and stability, does not, conversely, drive phosphorylation of the chartins. Instead, taxol appeared to decrease the turnover of phosphate in microtubule-associated, acidic chartin isoforms. These data suggest several models as to how chartin phosphorylation is regulated in neurite-bearing cells and indicate that phosphorylation of cytoplasmic and microtubule-associated chartins occurs via different mechanisms.

La présente étude consiste à tester les potentialités d'un hélophyte : le roseau (Arundo donax) à épurer une eau usée urbaine sous un climat aride. Le pilote expérimental est constitué de bacs de 115 litres de capacité, remplis sur une épaisseur de 5 cm de gravier et de 30 cm de sol (texture : limono-argilo-sableuse). Deux bacs sont plantés de jeunes tiges de roseaux. Deux autres bacs non plantés sont pris comme témoins. L'alimentation du système se fait exclusivement par des eaux usées urbaines en bâchées de 25 litres/jour et ce avec une fréquence régulière d'une fois par semaine. L'écoulement se fait par translation verticale à travers le substrat. L'eau de percolation est récupérée au moyen d'un drain placé à la base de chaque bac. L'étude du fonctionnement hydrologique des pilotes testés, a montré que le débit moyen à la sortie du lit planté (254 ml/min) est cinq fois plus élevé par rapport au lit non planté (51 ml/min). Ce qui permet soit de traiter un volume d'eau usée plus important ou bien de réduire la superficie nécessaire par équivalent habitant. En plus, il apparaît que la présence du roseau aide d'une part à prévenir le colmatage qui est un problème fréquent dans le sol non planté et d'autre part de maintenir une porosité suffisante pour assurer la percolation des eaux en traitement. Le suivi des performances épuratoires du système à roseau montre que ce dernier assure une élimination importante de la charge organique (MES : 91%, DCO : 72%). Il fournit des eaux épurées claires et limpides. Ces résultats sont comparables à ceux du sol non planté. La réduction de NTK est de l'ordre de 53% pour le lit planté contre 41% pour le sol nu. En général, le lit planté est plus efficace dans l'élimination de l'azote. Concernant l'élimination des ions ammoniums, le taux d'abattement moyen pour le lit planté est de 24%. Le sol non planté présente une surcharge de l'effluent à la sortie en ammonium (-17%). Le phosphore total et les orthophosphates subissent globalement un faible abattement avec des phases de relargage et d'autres d'abattement. L'abattement moyen obtenu par le système planté ne dépasse pas 28% et 10% respectivement pour le PT et les PO4. Dans le système non planté, il se produit un relargage de phosphore qui se maintient sur une longue période durant la 1ère année et qui se répète également en 2ème année de fonctionnement avec une intensité moins importante. L'abattement moyen obtenu est de -8% et -33% respectivement pour le PT et les PO4. En tenant compte des pertes d'eau par évapotranspiration, la correction effectuée a montré une nette amélioration des performances épuratoires surtout pour le sol planté où les pertes de volume sont considérables. Dans ce cas l'abattement moyen obtenu pour le lit planté est de 68%, 48%, 52% et 39% respectivement pour NTK, NH4, PT et PO4. Pour le sol non planté, les abattements sont plus faibles (NTK : 51%, NH4 : 3%, PT : 12%, PO4 : -8%). La présence du roseau dans le système planté assure donc une nette amélioration de l'abattement de la charge organique et des nutriments par rapport au sol nu. Cette amélioration est faible (3 à 7%) pour la DCO et les MES, par contre pour les nutriments, elle est beaucoup plus importante (17 à 48%). Concernant la charge parasitaire, les deux systèmes planté et non planté, assurent une élimination totale des œufs d'helminthes parasites. Pour les kystes de protozoaires, le système planté assure une réduction de 99,8%. Avec l'épaisseur du substrat testée, les risques de détecter des kystes de protozoaires à la sortie des systèmes plantés est à appréhender. Selon la norme de l'OMS, l'effluent de sortie du système est classé en catégorie B. Le roseau produit une biomasse importante qui atteint 176,5 tonnes/ha. La biomasse aérienne facilement éliminée par faucardage est de 85,3 T/ha. Le taux d'azote et de phosphore exporté avec cette biomasse atteint 98,54 et 4,15 g/m2 respectivement. Ces taux retenus au niveau des parties aériennes représentent 12% de la charge reçue par le système en azote et 3% de la charge reçue en phosphore.

AbstractIn this work, new synthetic nanophosphor materials of Li+ doped Ag3PO4 orthophosphate were prepared with different impurity concentrations. The coprecipitation method was utilized in the preparation at room temperature. The prepared nanophosphors were characterized via x-ray diffraction and high-resolution transmission electron microscopy, and the results confirmed the existence of nanoparticles. The thermoluminescence properties of samples with different concentrations of Li-cohost salt were extensively studied. The Ag3PO4 sample doped with 5 Wt% of Li (i.e. APL5) impurity revealed the highest thermoluminescence intensity of any of the other compositions, according to the thermoluminescence response of the synthesized nanophorsphors. All the studied samples were subjected to optimum thermal annealing of 500 °C for 1 h and readout with thermoluminescence reader at a heating rate of 5 °C/s. The APL5 nanophosphor samples revealed a good linearity dependence of thermoluminescence response against gamma dose within the range of 15–100 Gy. This sample showed a relatively low rate of fading of about 19% within two months of storage and good reusability. These characteristics make the newly prepared APL5 phosphor highly considered as a new potential thermoluminescence dosimeter and can be efficiently used in various γ-radiation detection applications.

The process of land occupation in Goiânia demonstrates that, owing to its accelerated populational growth, the city reproduced all the socioenvironmental contradictions of a big metropolis. This study reports an evaluation of the physical, chemical and microbiological characteristics of the Vaca Brava Stream, with a temporal and spatial analyses of its limnological characteristics. The samples collecting was carried out in eight points along the longitudinal axis of the Vaca Brava Stream between June 2015 and May 2016, encompassing the rainy and dry seasons. Twenty-seven physical-chemical and biological parameters were monitored. For the results a principal component analysis (PCA) was performed, with the t-test to verify differences between the collecting periods (dry and rainy). In a general manner, the results indicated waters with low values of turbidity, nutrients, DBO5 and Chlorophyll-a. However, there were exceptions, as the high concentrations of total phosphor, orthophosphate, total nitrogen (Kjeldahl), and ammoniacal nitrogen, recorded in some places during the dry season. Low concentrations of dissolved oxygen were also frequent in the study area. The results point to an expected seasonality which may be related to a larger contribution of polluting sources. The protection of the Vaca Brava Stream headwaters contributes to better values in the sampling points located upstream, most probably owing to the fact of the VBMP. The disorderly human occupation is reflected in the higher housing concentration (especially vertical) in the intermediary parts of the Vaca Brava Stream, being coherent with the more negative results expressed in this stretch of the stream. Among all sampling points, the most relevant for the majority of alterations is the Point 5, which might be reflecting the effluent loads coming from sewers, commerce, and small industries as channeled form or surface runoff in the rainy season. Avaliação da Qualidade da Água do Córrego Vaca Brava: contribuições para Ciências Ambientais e Saúde O processo de ocupação do solo em Goiânia demostra que, devido ao seu acelerado crescimento populacional, a cidade reproduziu todas as contradições socioambientais de uma grande metrópole. Esse estudo relata uma avaliação das características físicas, químicas e microbiológicas do córrego Vaca Brava, com uma análise da variação temporal e espacial das suas características limnológicas. A coleta das amostras foi realizada em oito pontos no eixo longitudinal do córrego Vaca Brava, entre junho de 2015 e maio de 2016, abrangendo as estações de chuva e seca. Foram monitorados 27 parâmetros físico-químicos e biológicos. Para os resultados foi realizada uma análise de componentes principais (PCA), com o teste t para verificar a existência de diferença entre os períodos de coleta (seca e chuva). De maneira geral, os resultados indicaram águas com baixos valores de turbidez, nutrientes, DBO5 e Clorofila-a. No entanto, ocorreram exceções, como as elevadas concentrações de fósforo total, ortofosfato, nitrogênio total (Kjeldahl) e nitrogênio amoniacal registradas em alguns locais no período de seca. Baixas concentrações de oxigênio dissolvido também foram frequentes na área de estudo. Os resultados apontam para uma sazonalidade esperada, que podem estar correlacionados a uma maior contribuição de fontes poluentes. A proteção das cabeceiras do córrego Vaca Brava contribui para valores amenos nos pontos amostrais mais à jusante, muito provavelmente devido ao fato da criação do PMVB. A ocupação humana desordenada se reflete na maior concentração de residências (especialmente verticais) nas partes intermediárias do córrego Vaca Brava, sendo coerente com os resultados mais negativamente expressivos nesse trecho do córrego. Dentre todos os pontos amostrais, o de maior relevância para a maioria das alterações é o Ponto 5, que pode estar refletindo cargas de efluentes advindas de esgotos, comércio e pequenas indústrias, seja de forma canalizada ou por enxurradas na estação chuvosa.

AbstractT-cell activation and cellular expansion by common gamma chain cytokines such as Interleukin-2 is necessary for adaptive immunity. However, when unregulated these same pathways promote pathologies ranging from autoimmune disorders to cancer. While the functional role of Interleukin-2 and downstream effector molecules is relatively clear, the repertoire of phosphoregulatory proteins downstream of this pathway is incomplete. To identify phosphoproteins downstream of common gamma chain receptor, YT cells were radiolabeled with [32P]-orthophosphate and stimulated with Interleukin-2. Subsequently, tyrosine phosphorylated proteins were immunopurified and subjected to tandem mass spectrometry—leading to the identification of CrkL. Phosphoamino acid analysis revealed concurrent serine phosphorylation of CrkL and was later identified as S114 by mass spectrometry analysis. S114 was inducible through stimulation with Interleukin-2 or T-cell receptor stimulation. Polyclonal antibodies were generated against CrkL phospho-S114, and used to show its inducibility by multiple stimuli. These findings confirm CrkL as an Interleukin-2 responsive protein that becomes phosphorylated at S114 by a kinase/s downstream of PI3K and MEK/ERK signaling.

ZusammenfassungIn der vorliegenden Studie wurde die Wirksamkeit einer Adsorptions‑/Fällmittel-Prototypsuspension der Firma Donau Chemie AG zur simultanen Entfernung von Spurenstoffen und Phosphor aus kommunalem Abwasser untersucht. Die Suspension enthält Polyaluminiumchlorid zur Fällung von gelöstem Orthophosphat, Pulveraktivkohle (PAK) zur Adsorption von organischen Spurenstoffen sowie anorganische Stabilisatoren, die die Suspension der PAK unterstützen. Vergleichende Laborversuche mit herkömmlicher PAK und der Prototypsuspension mit einem PAK-Gehalt von 16,5 % wurden mittels zweier unabhängiger Methoden (Spurenstoffanalytik und In-vitro-Bioassays) bewertet. Die Ergebnisse zeigten, dass die Suspension zu einer Verbesserung der Oberflächeneigenschaften der Aktivkohle führt und somit eine höhere Anzahl von bekannten und unbekannten Substanzen adsorbiert werden kann. Die Anwendbarkeit der Suspension wurde in drei verschiedenen Abwässern untersucht und ist vor allem vom Verhältnis zwischen gelöstem organischem Kohlenstoff (dissolved organic carbon – DOC) und Gesamtphosphor im Zulauf abhängig. Bei höheren DOC-Konzentrationen ist ein höherer Anteil an PAK in der Suspension notwendig, um eine massive Überdosierung des Fällmittels zu verhindern. Während des großtechnischen Versuchs, der auf einer kommunalen Kläranlage durchgeführt wurde, kam es zu einem Anstieg der prozentuellen Entfernung um mehr als 90 % für Carbamazepin, mehr als 50 % für Diclofenac und Metoprolol und um etwa 30 % für Benzotriazol. Bei einer konstanten Dosiermenge von 90 L d−1 wurde die auf Basis der Labortests erwartete Spurenstoffentfernung von mehr als 75 % für alle Stoffe erreicht. Der Prototyp zeigte sich als einfacher zu lagern und zu dosieren als herkömmliche PAK. Weiters kann die vorhandene Infrastruktur für die chemische Phosphorfällung für die organische Spurenstoffentfernung mitgenutzt werden.
