    2012-01-01

    Hannes came to CERN in October 1973 to take up a post with the Computer Operations Group in DD Division, leaving Stuttgart where he had been working up until then.   He quickly settled into the task of computer operations, becoming a very valued member of the team, demonstrating excellent skills in both technical knowledge and human relations. The latter was helped by his excellent command of both English and French, despite having had very little training in this particular domain. He was much appreciated by his colleagues for his calmness and approachability, and was popularly known as “Schwarzy”, a name which followed him throughout his entire CERN career. Following the outsourcing of the computer operations service in 1991, he moved to the User Support Group, where he had already assisted with the Help Desk. He continued developing his computing skills such that he provided PC 2nd level support, successfully deflecting many user queries away from the PC Group. He hel...

    Mein, P.G.

    1984-01-01

    Cesium is recovered from cesium alum, CsAl(SO 4 ) 2 , by a two-reaction sequence in which the cesium alum is first dissolved in an aqueous hydroxide solution to form cesium alum hydroxide, CsAl(OH) 3 , and potassium sulfate, K 2 SO 4 . Part of the K 2 SO 4 precipitates and is separated from the supernatant solution. In the second reaction, a water-soluble permanganate, such as potassium permanganate, KMnO 4 , is added to the supernatant. This reaction forms a precipitate of cesium permanganate, CsMnO 4 . This precipitate may be separated from the residual solution to obtain cesium permanganate of high purity, which can be sold as a product or converted into other cesium compounds

    Full Text Available Fecal samples from 24 animals of eight different species were collected at Hann Zoological Park in Senegal. They were analyzed with the Telemann-Rivas qualitative microscopic method and Mac Master quantitative method. Of all the samples, 66.7% were positive, and each positive animal was infested with at least one helminth egg species, whereas protozoa were present in only four animals. In carnivores, the eggs of parasites such as Toxascaris leonina and Toxocara cati, and hookworm eggs were the most present, whereas in primates, the eggs of Trichuris sp. and Entamoeba sp. have been identified. This study provides a basis for the establishment of treat­ments in these animals.

  3. Method of distillation of alum shale

    1920-02-03

    A method is given of distilling alum shale by means of preheated gases obtained from the process of distillation in which the gases are circulating within a system consisting of the retort, the condensation apparatus, and generator, each separate. It is characterized by leading the gases produced during the distillation through a condensation apparatus for separation of the condensable products, such as oil, benzene, ammonia, and sulfur, and the noncondensable gases are conveyed through one or more heated generators that have been charged with residue from the process of distillation (any superfluous amount of gas formed during the process being released). The heated gases are thereupon passed to the retort for completion of the distillation process.

  4. Secondary sulfate minerals from Alum Cave Bluff: Microscopy and microanalysis

    Energy Technology Data Exchange (ETDEWEB)

    1997-07-01

    Microcrystals of secondary sulfate minerals from Alum Cave Bluff, Great Smoky Mountains National Park, were examined by scanning electron microscopy and identified by X-ray fluorescence (XRF) in the SEM. Among the samples the author discovered three new rare-earth sulfates: coskrenite-(Ce), levinsonite-(Y), and zugshunstite-(Ce). Other minerals illustrated in this report include sulfur, tschermigite, gypsum, epsomite, melanterite, halotrichite, apjohnite, jarosite, slavikite, magnesiocopiapite, and diadochite. Additional specimens whose identification is more tentative include pickeringite, aluminite, basaluminite, and botryogen. Alum Cave is a ``Dana locality`` for apjohnite and potash alum, and is the first documented North American occurrence of slavikite.

    Solo-Ngawi toll road project is part of the mega project of the Trans Java toll road development initiated by the government and is still under construction until now. PT Solo Ngawi Jaya (SNJ) as the Solo-Ngawi toll management company needs to determine the toll fare that is in accordance with the business plan. The determination of appropriate toll rates will affect progress in regional economic sustainability and decrease the traffic congestion. These policy instruments is crucial for achieving environmentally sustainable transport. Therefore, the objective of this research is to find out how the toll fare sensitivity of Solo-Ngawi toll road based on Willingness To Pay (WTP). Primary data was obtained by distributing stated preference questionnaires to four wheeled vehicle users in Kartasura-Palang Joglo artery road segment. Further data obtained will be analysed with logit and probit model. Based on the analysis, it is found that the effect of fare change on the amount of WTP on the binomial logit model is more sensitive than the probit model on the same travel conditions. The range of tariff change against values of WTP on the binomial logit model is 20% greater than the range of values in the probit model . On the other hand, the probability results of the binomial logit model and the binary probit have no significant difference (less than 1%).

  11. The riddles of foehn. Introduction to the historic articles by Hann and Ficker

    Energy Technology Data Exchange (ETDEWEB)

    Seibert, Petra [University of Natural Resources and Life Science Vienna (Austria). Inst. of Meteorology; Vienna Univ. (Austria). Dept. of Meteorology and Geophysics

    2012-12-15

    Two key papers on the topic of foehn are introduced. The first one, published in 1885 by Julius Hann, discusses the history of the 'thermodynamic foehn theory', and the role of the various scientists who contributed to its evolution. Emphasis is placed on the early recognition of important aspects by J.P. Espy which was not properly recognised in Europe at the time of publication (around 1850). Hann's article is very interesting also because it permits insight into the role of social factors for the acceptance of scientific theories, involving two of the most important meteorologists of the 19th century, W. Dove and J. Hann himself. The second paper was published in 1910 by Heinrich Ficker and discusses theories for the process of foehn break-through which are evaluated on the base of Ficker's mesonet in the area of Innsbruck and surroundings. Finally, the most important developments in foehn research in the past 100 years, since the appearance of Ficker's article, are very briefly sketched. (orig.)

    Insect bite hypersensitivity (IBH) is an IgE-mediated dermatitis of horses caused by bites of Culicoides insects, not indigenous to Iceland. Horses born in Iceland and exported to Culicoides-rich areas are frequently affected with IBH. The aims of the study were to compare immunization with recombinant allergens using the adjuvant aluminum hydroxide (Alum) alone or combined with monophosphoryl lipid A (MPLA) for development of a preventive immunization against IBH. Twelve healthy Icelandic horses were vaccinated intralymphatically three times with 10 μg each of four recombinant Culicoides nubeculosus allergens in Alum or in Alum/MPLA. Injection with allergens in both Alum and Alum/MPLA resulted in significant increase in specific IgG subclasses and IgA against all r-allergens with no significant differences between the adjuvant groups. The induced antibodies from both groups could block binding of allergen specific IgE from IBH affected horses to a similar extent. No IgE-mediated reactions were induced. Allergen-stimulated PBMC from Alum/MPLA horses but not from Alum only horses produced significantly more IFNγ and IL-10 than PBMC from non-vaccinated control horses. In conclusion, intralymphatic administration of small amounts of pure allergens in Alum/MPLA induces high IgG antibody levels and Th1/Treg immune response and is a promising approach for immunoprophylaxis and immunotherapy against IBH.

    The effectiveness of many vaccines licensed for clinical use relates to the induction of neutralising antibodies, facilitated by the inclusion of vaccine adjuvants, particularly alum. However, the ability of alum to preferentially promote humoral rather than cellular, particularly Th1-type responses, is not well understood. We demonstrate that alum activates immunosuppressive mechanisms following vaccination, which limit its capacity to induce Th1 responses. One of the key cytokines limiting excessive immune responses is IL-10. Injection of alum primed draining lymph node cells for enhanced IL-10 secretion ex vivo. Moreover, at the site of injection, macrophages and dendritic cells were key sources of IL-10 expression. Alum strongly enhanced the transcription and secretion of IL-10 by macrophages and dendritic cells. The absence of IL-10 signalling did not compromise alum-induced cell infiltration into the site of injection, but resulted in enhanced antigen-specific Th1 responses after vaccination. In contrast to its decisive regulatory role in regulating Th1 responses, there was no significant change in antigen-specific IgG1 antibody production following vaccination with alum in IL-10-deficient mice. Overall, these findings indicate that injection of alum promotes IL-10, which can block Th1 responses and may explain the poor efficacy of alum as an adjuvant for inducing protective Th1 immunity. © 2018 WILEY-VCH Verlag GmbH & Co.

    2015-04-01

    Alum salts are commonly used in the water industry to promote coagulation in the production of clean drinking water, which results in the generation and accumulation of 'waste' by-product 'alum sludge' in large volumes. Effective and efficient management of alum sludge in an economically and environmentally sustainable manner remains a significant social and environmental concern with ever increasing demand for potable water as a result of rapidly escalating world population and urban expansion. Various intensive practices have been employed to reuse the alum sludge in an attempt to figure out how to fill the gap between successful drinking water treatment process and environmentally friendly alum sludge management for over the years. This paper primarily aimed at comprehensive review of the existing literature on alum sludge characteristics, its environmental concerns and their potential utilization, especially in agricultural and horticultural sectors leading to update our recent state of knowledge and formulate a compendium of present and past developments. Different types of alum sludge utilizations in various fields were recognized and examined. The strengths, weaknesses, opportunities and potential risks of alum sludge reuse options with particular reference to agriculture were highlighted and knowledge gaps were identified. Research priorities and future challenges that will support in the development of effective alumsludgemanagement practices in agriculture with multi-prong strategies were discussed.

    Full Text Available This study applies a process to treat ammonium-rich wastewater using alum-generated sludge form water purification plant, and gain economic benefit by producing ammonium alum (Al(NH4(SO42·12H2O. The factors affecting production of ammonium alum include molar ratio of ammonium to aluminum concentration, sulfuric acid concentration, mixing speed, mixing time, standing time, and temperature. According to the equation for the ammonium removal reaction, the theoretical quantity of ammonium alum was calculated based on initial and final concentrations of ammonium. Then, the weight of ammonium alum crystal was divided by the theoretical weight to derive the recovery ratio. The optimum sludge and sulfuric acid dosage to treat about 17 g L−1 ammonium wastewater are 300 g L−1 and 100 mL L−1, respectively. The optimal dosage for wastewater is molar ratio of ammonium to aluminum of about 1 due to the aluminum dissolving in acidified wastewater. The ammonium removal efficiency is roughly 70% and the maximum recovery ratio for ammonium alum is 93% when the wastewater is mixed for 10 min at the mixing velocity gradient of 100 s−1. Ammonium alum production or ammonium removal can be enhanced by controlling the reaction at low temperatures.

    Full Text Available RESUMEN Hannes Meyer fue uno de los arquitectos más comprometidos con las ideas del ala radical del racionalismo, que él mismo y otros grandes arquitectos, como Mart Stam, Hans Wittwer, Karel Teige, Ludwig Hilberseimer o Ernst May, desarrollaron durante la década de los años veinte. Su voluntad de desvincular la arquitectura del “high–art” burgués y de todo simbolismo propio del pasado, de producir construcciones de carácter objetivo y social, quedó patente en proyectos y obras firmadas por todos ellos: en el caso de Meyer, probablemente, la construcción que mejor expresa tales postulados y aquel nuevo modo de hacer arquitectura sea la Escuela Federal ADGB; construida en Bernau entre 1928 y 1930. El presente artículo estudia la citada obra, a la luz del ideario arquitectónico y social de arquitecto suizo, y trata de exponer la estrategia que se encuentra detrás de su formalización: la serie. En efecto, a partir de este mecanismo de proyecto, basado en la repetición o reproducción casi infinita de sistemas constructivos o de unidades del programa–o de ambas al mismo tiempo–aquellos arquitectos descubrieron un nuevo modo de generar la forma arquitectónica, moderno y muy poco explorado hasta entonces. Una vía donde valores como la horizontalidad, la ausencia de centro o jerarquía, la igualdad y la objetividad se erigían como el nuevo relato de la arquitectura. SUMMARY Hannes Meyer was one of the most committed architects to the ideas of the radical wing of rationalism, which he himself and other great architects, such as Mart Stam, Hans Wittwer, Karel Teige, Ludwig Hilberseimer and Ernst May, developed during the twenties.

    Alum [Al(2)(SO(4))(3).14H(2)O] is a common poultry litter amendment used to decrease water-soluble phosphorus or reduce ammonia volatilization, or both. Although the physiochemical effects of alum addition have been well researched, little attention has been given to the poultry litter microbial communities. The goal of this study was to use molecular biological methods [denaturing gradient gel electrophoresis (DGGE), community cloning, and quantitative real-time PCR] to characterize general, group-specific and pathogenic microbial communities in alum (10% wt/wt) and non-alum-treated litter. According to quantitative real-time PCR analyses, alum addition to the poultry litter resulted in significant reductions in both Campylobacter jejuni and Escherichia coli concentrations by the end of the first month of the experiment (3 log and 2 log, respectively). The concentrations of Salmonella spp. were below detection (Eubacterium and low %GC gram-positive groups in the alum-treated litters by the end of the first month, with no bands detectable for either group after 8 wk of incubation. Conversely, minimal effects of alum addition were observed in the Actinomycetes community. The most significant shift in the microbial community (based on DGGE analyses) occurred in the fungal population, with a large increase in diversity and abundance within 1 mo of alum addition (1 dominant band on d 0 to 9 dominant bands at 4 wk). Specifically, the incidence of Aspergillus spp. increased from 0 to 50% of the sequences in fungal clone libraries (n = 80) over the course of the experiment. This suggests that the addition of alum to poultry litter potentially shifts the microbial populations from bacterially dominated to dominated by fungi. The ramifications of this shift in dominance are still unknown, and future work will be aimed at characterizing these fungi and elucidating their role in the acidified litter environment.

    Full Text Available The concentration of alum additive in deep-fried dough sticks (DFDSs was investigated using a coaxial probe method based on dielectric properties in the 0.3–10-GHz frequency range. The dielectric spectra of aqueous solutions with different concentrations of alum, sodium bicarbonate, and mixtures thereof were used. The correspondence between dielectric loss and alum concentration was thereby revealed. A steady, uniform correspondence was successfully established by introducing ω·ε″(ω, the sum of dielectric loss and conductor loss (i.e., total loss, according to the electrical conductivity of the alum-containing aqueous solutions. Specific, resonant-type dielectric dispersion arising from alum due to atomic polarization was identified around 1 GHz. This was used to discriminate the alum additive in the DFDS from other ingredients. A quantitative relationship between alum and sodium bicarbonate concentrations in the aqueous solutions and the differential dielectric loss Δε″(ω at 0.425 GHz was also established with a regression coefficient over 0.99. With the intention of eliminating the effects of the chemical reactions with sodium bicarbonate and the physical processes involved in leavening and frying during preparation, the developed technique was successfully applied to detect the alum dosage in a commercial DFDS (0.9942 g/L. The detected value agreed well with that determined using graphite furnace atomic absorption spectrometry (0.9722 g/L. The relative error was 2.2%. The results show that the proposed dielectric differential dispersion and loss technique is a suitable and effective method for determining the alum content in DFDSs.

    In this study, the efficiency of Moringa stenopetala seed extract was compared with alum and M. stenopetala-alum hybrid coagulant to remove Direct Red 23 azo dye from textile wastewater. The effects of parameters such as pH, coagulant dose, type of salt used for the extraction of coagulant and initial dye concentration on dye removal efficiency were investigated. Moreover, the existing functional groups on the structure of M. stenopetala coagulant (MSC) were determined by Fourier transform infrared spectroscopy, and the morphology of sludge produced by MSC, alum, and hybrid coagulant was characterized by scanning electron microscopy. Ninhydrin test was also used to determine the quantity of primary amines in the MSC and Moringa oleifera coagulant (MOC). According to the results, with increasing the coagulant dose and decreasing the initial dye concentration, dye removal efficiency has increased. The maximum dye removal of 98.5, 98.2, and 98.3 % were obtained by using 240, 120, and 80 mg/L MSC, alum and hybrid coagulant at pH 7, respectively. The results also showed MSC was much more effective than MOC for dye removal. The volume of sludge produced by MSC was one fourth and half of those produced by alum and hybrid coagulant, respectively. Based on the results, hybrid coagulant was the most efficient coagulant for direct dye removal from colored wastewater.

  10. Safety and efficacy of intravesical alum for intractable hemorrhagic cystitis: a contemporary evaluation

    Full Text Available ABSTRACT Introduction: Hemorrhagic cystitis (HC represents a challenging clinical entity. While various intravesical agents have been utilized in this setting, limited data exist regarding safety or efficacy. Herein, then, we evaluated the effectiveness and complications associated with intravesical alum instillation for HC in a contemporary cohort. Materials and Methods: We identified 40 patients treated with intravesical alum for HC between 1997-2014. All patients had failed previous continuous bladder irrigation with normal saline and clot evacuation. Treatment success was defined as requiring no additional therapy beyond normal saline irrigation after alum instillation. Results: Median patient age was 76.5 years (IQR 69, 83. Pelvic radiation was the most common etiology for HC (n=38, 95%. Alum use decreased patient's transfusion requirement, with 82% (32/39 receiving a transfusion within 30 days before alum instillation (median 4 units versus 59% (23/39 within 30 days after completing alum (median 3 units (p=0.05. In total, 24 patients (60% required no additional therapy prior to hospital discharge. Moreover, at a median follow-up of 17 months (IQR 5, 38.5, 13 patients (32.5% remained without additional treatment for HC. Adverse effects were reported in 15 patients (38%, with bladder spasms representing the most common event (14/40; 35%. No clinical evidence of clinically significant systemic absorption was detected. Conclusion: Intravesical alum therapy is well-tolerated, with resolution of HC in approximately 60% of patients, and a durable response in approximately one-third. Given its favorable safety/efficacy profile, intravesical alum may be considered as a first-line treatment option for patients with HC.

    In view of the well recognized need of reject water treatment in MWWTP (municipal wastewater treatment plant), this paper outlines two strategies for P removal from reject water using alum sludge, which is produced as by-product in drinking water treatment plant when aluminium sulphate is used for flocculating raw waters. One strategy is the use of the alum sludge in liquid form for co-conditioning and dewatering with the anaerobically digested activated sludge in MWWTP. The other strategy involves the use of the dewatered alum sludge cakes in a fixed bed for P immobilization from the reject water that refers to the mixture of the supernatant of the sludge thickening process and the supernatant of the anaerobically digested sludge. Experimental trials have demonstrated that the alum sludge can efficiently reduce P level in reject water. The co-conditioning strategy could reduce P from 597-675 mg P/L to 0.14-3.20 mg P/L in the supernatant of the sewage sludge while the organic polymer dosage for the conditioning of the mixed sludges would also be significantly reduced. The second strategy of reject water filtration with alum sludge bed has shown a good performance of P reduction. The alum sludge has P-adsorption capacity of 31 mg-P/g-sludge, which was tested under filtration velocity of 1.0 m/h. The two strategies highlight the beneficial utilization of alum sludge in wastewater treatment process in MWWTP, thus converting the alum sludge as a useful material, rather than a waste for landfill.

    Phosphorus (P) losses from pastures fertilized with poultry litter contribute to the degradation of surface water quality in the United States. Dietary modification and manure amendments may reduce potential P runoff losses from pastures. In the current study, broilers were fed a normal diet, phytase diet, high available phosphorus (HAP) corn diet, or HAP corn + phytase diet. Litter treatments were untreated control and alum added at 10% by weight between flocks. Phytase and HAP corn diets reduced litter dissolved P content in poultry litter by 10 and 35%, respectively, compared with the normal diet (789 mg P kg(-1)). Alum treatment of poultry litter reduced the amount of dissolved P by 47%, while a 74% reduction was noted after alum treatment of litter from the HAP corn + phytase diet. The P concentrations in runoff water were highest from plots receiving poultry litter from the normal diet, whereas plots receiving poultry litter from phytase and HAP corn diets had reduced P concentrations. The addition of alum to the various poultry litters reduced P runoff by 52 to 69%; the greatest reduction occurred when alum was used in conjunction with HAP corn and phytase. This study demonstrates the potential added benefits of using dietary modification in conjunction with manure amendments in poultry operations. Integrators and producers should consider the use of phytase, HAP corn, and alum to reduce potential P losses associated with poultry litter application to pastures.

    Full Text Available With the foundation of the Bauhaus, Walter Gropius advocated an end to the division between arts and crafts. Contrary to the idea of architecture as art, the programme of the school aimed to assimilate architecture with industry in order to satisfy collective social needs. Yet, despite this programmatic declaration, such a project was realised only after Gropius’ departure from the Bauhaus, under the controversial directorship (1927–1930 of the Swiss architect Hannes Meyer. Meyer achieved unprecedented success both in terms of academic production and financial performance. Yet his realisations were paralleled by the leftist radicalisation of the school’s politics: Meyer transformed the workshops into factory production units and the students into industrial workers. Eventually, the politicisation of the school cost Meyer his office and a negative reputation in historical records that still holds today. This article posits that Meyer achieved his success at the Bauhaus not despite his radical allegiance, but precisely because of it. The realism of Meyer’s strategy is evaluated through his capacity to anticipate many developments in the organisation of architectural production. In particular, his critique of intellectual labour in architecture is confronted with the contemporary proletarisation of architects in the Western world.

    Aluminum oxyhydroxide (alum) is a crystalline compound widely used as an immunologic adjuvant of vaccines. Concerns linked to alum particles have emerged following recognition of their causative role in the so-called macrophagic myofasciitis (MMF) lesion in patients with myalgic encephalomyelitis, revealing an unexpectedly long-lasting biopersistence of alum within immune cells and a fundamental misconception of its biodisposition. Evidence that aluminum-coated particles phagocytozed in the injected muscle and its draining lymph nodes can disseminate within phagocytes throughout the body and slowly accumulate in the brain further suggested that alum safety should be evaluated in the long term. However, lack of specific staining makes difficult the assessment of low quantities of bona fide alum adjuvant particles in tissues. We explored the feasibility of using fluorescent functionalized nanodiamonds (mfNDs) as a permanent label of alum (Alhydrogel(®)). mfNDs have a specific and perfectly photostable fluorescence based on the presence within the diamond lattice of nitrogen-vacancy centers (NV centers). As the NV center does not bleach, it allows the microspectrometric detection of mfNDs at very low levels and in the long-term. We thus developed fluorescent nanodiamonds functionalized by hyperbranched polyglycerol (mfNDs) allowing good coupling and stability of alum:mfNDs (AluDia) complexes. Specificities of AluDia complexes were comparable to the whole reference vaccine (anti-hepatitis B vaccine) in terms of particle size and zeta potential. In vivo, AluDia injection was followed by prompt phagocytosis and AluDia particles remained easily detectable by the specific signal of the fND particles in the injected muscle, draining lymph nodes, spleen, liver and brain. In vitro, mfNDs had low toxicity on THP-1 cells and AluDia showed cell toxicity similar to alum alone. Expectedly, AluDia elicited autophagy, and allowed highly specific detection of small amounts of alum

    The highest activities in commonly used Swedish building materials are found in aerated concrete based on alum shale. The enhanced activity level is due to the high content of radium-226. The average activity concentration of radium-226 varies between different producers of aerated concrete based on alum shale from 700 Bq kg - (20 pCi g - ) to 2 400 Bq kg - (65 pCi g - ). Houses built in the same way with the same amounts of aerated concrete can therefore have very different gamma levels and very different concentrations of radon in the air with the same air exchange rate. Aerated concrete based on alum shale was used as a building material in Sweden from 1930 to 1975. The average concentration of radon daughters found in houses built of aerated concrete based to a major extent on alum shale is about 100 bq/m 3 (2.7 pCi 1 - ). The highest radon concentrations have been found in houses built entirely of aerated concrete based on alum shale. A group of 9 houses with natural draught ventilation systems has been investigated with regard to the concentration of radon, the equilibrium equivalent concentration of radon (EEC) and the gamma dose rate. The air exchange rates varied between the houses from 0.21 to 0.43 h - and the radon concentration from 540 Bq m - (15 pCi 1 - ) to 1 160 Bq m - (31 pCi 1 - ). The values given are averages for each house. (author)

    The crystal structures of the three alums: NH 4 Al(SO 4 ) 2 .12H 2 O, (NH 3 CH 3 )Al(SO 4 ) 2 .12H 2 O and (NH 3 OH)Al(SO 4 ) 2 .12H 2 O have been determined from three-dimensional neutron diffraction data enhanced by X-ray diffraction when necessary. These compounds crystallize cubic in space group Pa3. The structures of the three alums exhibit partial occupancies of crystallographic sites for the NH 4 , (NH 3 CH 3 ) and (NH 3 OH) group atoms. This can be explained by a quantized rotation of the three groups around an axis perpendicular to the [111] direction. Some of the (SO 4 ) 2- groups in the NH 4 -alum are disordered with about 17% of the sulfate tetrahedra being in a reversed orientation around the sulfur atom. The disorder in (NH 3 CH 3 ) and (NH 3 OH)-alums is only 4,3% and 3.0% respectively. The atoms in the alum structures are held together by a system of hydrogen bonds between the water molecules and between the water molecules and the sulfate oxygen atoms. In these three structures there is a strong indication that shorter hydrogen bonds tend to be nearly linear. (orig.)

    The crystal structure of the alums, (NH 3 CH 3 )Al(SO 4 ) 2 x 12 H 2 0 and (NH 4 )AL(SO 4 ) 2 x 12 H 2 0, has been determined and refined from X-ray and neutron diffraction data. The compounds crystallize cubic in space group Pa3 (Z = 4). The positional and thermal parameters of all atoms including hydrogens have been refined by full matrix least-sqares analysis resulting in Rsub(w) values from the X-ray and neutron data of 0.030 and 0.029 respectively for the methylammonium alum and of 0.024 and 0.014 respectively for the ammonium alum. The atoms of the cation groups (NH 3 CH 3 ) + and (NH 4 ) + are distributed on 8(c) and 24(d) positions in two orientations of equal probability on and around the [111] direction related to each other by an inversion centre. The disorder in the cation groups is explained by a quantized rotation. Disorder in the sulfate groups has been determined to 4.2% for the methylammonium alum and to about 17% for the ammonium alum. The disordered sulfate tetrahedra are distorted and in a reversed orientation along the threefold axis. The system of the hydrogen bonds is discussed. (orig.)

    Full Text Available Hanns-Josef Ortheil's early novels Fermer , 1979 and Hecke , 1983 have male protagonists who search for self-identity in the West Germany of the 1980s. In the process, they discover that they are profoundly influenced by the lives and experiences of their parents, particularly as these lives were shaped during and by the Hitler regime. In Fermer , the 19-year old protagonist rebels against this society by going AWOL. Yet in his geographical flight and intellectual analyses he realizes his deep emotional bonds with the expectations and behavior of the parent generation. Recognition of these bonds is only the first step on a Iong and painful road toward personally independent and politically responsible adulthood. An exploration of the key concepts of order and Geborgenheit (being protected reveals the deep-seated ambiguities in the postwar mentality of the parent generation as it is trying to instill these sentiments in their successors. The 30-year old protagonist of Hecke pieces together his mother's traumatized life during and after the Hitler regime in order to understand her emotionally stultifying hold on him. He comes to understand the manipulative power of her suffering and realizes that he must shed the burden of her displaced needs if he hopes to attain a conscious, mature self-identity. The use and the manipulation of language and its silences are the prime target of the narrator's efforts to penetrate the "protective hedges" of untold stories. Both novels conclude with the protagonists' intellectual insights into their psychological and socially conditioned make-up, but they do not—yet—carry these insights into action.

    Characterization and removal of natural organic matter, which is contained in the effluent of slow sand filters, was observed by alum coagulation under various dosages. In addition to non-purgedable dissolved organic carbon (NPDOC), trihalomethanes formation potential (THMFP) and haloacetic acid formation potential (HAAFP) measurement, high-performance size-exclusion chromatography (HPSEC) with ultraviolet/visible and dissolved organic carbon (DOC) detectors was used to characterize the various organic fractions contained in the water before and after coagulation. The results show that alum coagulation could effectively remove hydrophobic aromatic, which forms mainly humic substances. The reduction in THMFP was found to be higher than that of NPDOC and HAAFP under specific alum dosage, and the former was also found to be proportional to the corresponding reduction in the area of hydrophobic aromatic fraction, mostly humic subtances, as obtained from HPSEC chromatogram with peak-fitting.

    Coagulation is a primary and cost effective process in water treatment plants. Under optimum conditions, not only it effectively removes turbidity but also results in reduced sludge volume and subsequently minimizes sludge management costs. Highly turbid water from streams, canals, rivers and rain run offs was run through jar test for turbidity removal. The brown water with 250NTU turbidity when coagulated with alum and assorted coagulants proved that maximum turbidity removal was witnessed using alum dose of 0.25 g/l at ph 6 with a sedimentation time of 30 min.

At the end of the experiments sulfate had moved as expected towards the anode...... was not obtained in the experiments reported here, but the high conductivity and the transport of the measured ions due to the electric field indicates that an applied electric field as a method for removal of alum and other unwanted ions from treated wooden objects warrants further investigation....

    A European Phase III trial of GAD formulated with aluminium hydroxide (GAD-alum) failed to reach its primary endpoint (preservation of stimulated C-peptide secretion from baseline to 15 months in type 1 diabetes patients), but subgroup analysis showed a clinical effect when participants from Nordic countries were excluded, raising concern as to whether the mass vaccination of the Swedish and Finnish populations with the Pandemrix influenza vaccine could have influenced the study outcomes. In the current study, we aimed to assess whether Pandemrix vaccination affects the specific immune responses induced by GAD-alum and the C-peptide response. In this secondary analysis, we analysed data acquired from the Swedish participants in the Phase III GAD-alum trial who received subcutaneous GAD-alum vaccination (two doses, n = 43; four doses, n = 46) or placebo (n = 48). GAD autoantibodies (GADA) and H1N1 autoantibodies, GAD 65 -induced cytokine secretion and change in fasting and stimulated C-peptide levels from baseline to 15 months were analysed with respect to the relative time between H1N1 vaccination and the first injection of GAD-alum. GADA levels at 15 months were associated with the relative time between GAD-alum and Pandemrix administration in participants who received two doses of the GAD-alum vaccine (p = 0.015, r = 0.4). Both in participants treated with two doses and four doses of GAD-alum, GADA levels were higher when the relative time between vaccines was ≥210 days (p < 0.05). In the group that received two doses of GAD-alum, levels of several GAD 65 -induced cytokines were higher in participants who received the H1N1 vaccination and the first GAD-alum injection at least 150 days apart, and the change in fasting and stimulated C-peptide at 15 months was associated with the relative time between vaccines. Neither of these effects were observed in individuals who received four doses of GAD-alum. In individuals who received two doses of GAD-alum

    Over 1.1 billion people in the world lack access to improved drinking water. Diarrhoeal and other waterborne diseases cause an estimated 1.87 million deaths per year. The Safe Water System (SWS) is a household water treatment intervention that reduces diarrhoeal disease incidence among users in developing countries. Turbid waters pose a particular challenge to implementation of SWS programmes; although research shows that a 3.75 mg l(-1) sodium hypochlorite dose effectively treats turbid waters, users sometimes object to the strong chlorine taste and prefer to drink water that is more aesthetically pleasing. This study investigated the efficacy of two locally available chemical water treatments-alum and Moringa oleifera flocculation-to reduce turbidity and chlorine demand at turbidities of 10, 30, 70, 100 and 300 NTU. Both treatments effectively reduced turbidity (alum flocculation 23.0-91.4%; moringa flocculation 14.2-96.2%). Alum flocculation effectively reduced chlorine demand compared with controls at 30, 70, 100 and 300 NTU (p=0.01-0.06). Moringa flocculation increased chlorine demand to the point where adequate free chlorine residual was not maintained for 24 hours after treatment. Alum pretreatment is recommended in waters>or=30 NTU for optimum water disinfection. Moringa flocculation is not recommended before chlorination.

    Dual coagulant has the potential to improve the coagulation process. In leachate treatment coagulation/flocculation can be used as a main treatment method or as a polishing/tertiary treatment step. Application of natural coagulant as coagulant aids able to increase the formation of floc and the removal ability of the coagulation process. This study was focusing on the ability of dual coagulants made from chemical coagulant (Alum) and natural coagulant (Cicer Arietinum (CA)) in removing colour from leachate. Jar test was carried out to investigate the effect of dose and pH on the removal ability of the dual coagulant. The optimum pH and dose for dual coagulant were obtained at pH 6.0 with dose of Alum at 4 g/L and dose of CA at 0.6 g/L with 94% removal of colour. While the optimum removal of colour for single Alum (4 g/L) and single CA (1.4 g/L) were recorded as 88% and 22%, respectively. The removals obtained using single natural and chemical coagulants were not as good as those obtained by dual coagulant. Thus, addition of CA as a coagulant aid for alum, able to increase the removal of color from leachate and has the potential to be applied as a treatment method for leachate.

    The scheme of the process was worked out on the basis of small (the weight of starting ashes 1 kg) and big (76.2 kg) laboratory tests with the result of getting aluminium potassium sulphate (alum) as a commercial product, and a technological solution with increased content of metals (Ti, Mo, V, U, etc.). Ashes received by means of Toolse deposit (Estonia) alum-shale fluidized-bed ashing at 800 o C, were used as basic material. The ashes were sulphate d in combustion tubes provided with electric heater using sulphate roasting process: the ashes were mixed with 75% H 2 SO 4 with the ratio S : L = 4 : 3 to get a homogeneous paste which was calcinated in the tube at 250-300 o C for 30 min. The calcinated paste (clinker) was treated with boiling water. The leaching experiments were carried out with various S : L ratios; in small test - in 2-litre bulbs, equipped with a stirring-rod, reflux condenser and thermometer, in the pulp at boiling temperature (101 o C). The hot leaching pulp was filtered under pressure using forcing filters. The final solutions were cooled and treated in order to receive alum. Under the conditions of a discontinuous process, the yield of raw alum (content of Fe 2 O 3 ∼1%) made up 240-270 kg/t of the starting ashes, both at the expense of the ashes' own potassium and at the expense of the potassium added from outside. The standard alum with regard to the content of iron admixture was obtained after repeated recrystallization of the raw alum. After the separation of alum, the solutions with the specific weight of 1.4-1.5 t/m 3 , and with the following average metal and sulphuric acid content in the solutions of the small and big tests were obtained: Ti 4.8 and 8.3; Mo 0.4 and 0.8; V 1.0 and 1.9; U 0.2 and 0.5; Fe 66 and 90; Al 18 and 20; K 1.9 and 3.4; H 2 SO 4 117 and 123 g/l, respectively. The extraction of metals into the solution in small and big tests was as follows: ti 71 and 64, Mo 73 and 66, V94 and 86, U 91 and 77, Fe 69 and 60, Al 45

    An interdisciplinary study was carried out to unravel organic-inorganic interactions caused by the radiogenic decay of uranium in the immature organic-rich Alum Shale (Middle Cambrian-Lower Ordovician). Based on pyrolysis experiments, uranium content is positively correlated with the gas-oil ratios and the aromaticities of both the free hydrocarbons residing in the rock and the pyrolysis products from its kerogen, indicating that irradiation has had a strong influence on organic matter composition overall and hence on petroleum potential. The Fourier Transform Ion Cyclotron Resonance mass spectrometry data reveal that macro-molecules in the uranium-rich Alum Shale samples are less alkylated than less irradiated counterparts, providing further evidence for structural alteration by α-particle bombardment. In addition, oxygen containing-compounds are enriched in the uranium-rich samples but are not easily degradable into low-molecular-weight products due to irradiation-induced crosslinking. Irradiation has induced changes in organic matter composition throughout the shale's entire ca. 500 Ma history, irrespective of thermal history. This factor has to be taken into account when reconstructing petroleum generation history. The Alum Shale's kerogen underwent catagenesis in the main petroleum kitchen area 420-340 Ma bp. Our calculations suggest the kerogen was much more aliphatic and oil-prone after deposition than that after extensive exposure to radiation. In addition, the gas sorption capacity of the organic matter in the Alum Shale can be assumed to have been less developed during Palaeozoic times, in contrast to results gained by sorption experiments performed at the present day, for the same reason. The kerogen reconstruction method developed here precludes overestimations of gas generation and gas retention in the Alum Shale by taking irradiation exposure into account and can thus significantly mitigate charge risk when applied in the explorations for both

    Alum [KAl(SO)⋅12HO] is often added to chicken manure to limit P solubility after land application. This is generally ascribed to the formation of Al-PO complexes. However, Al-PO complex formation could be affected by the matrix of chicken manure, which varies with animal diet. Alum was added to KHPO (as a reference material) and two manures from typical chicken farms in China, one from an intensive farm (CMIF) and another from free-ranging chickens (CMFR). These were subsequently incubated with soils for 100 d to investigate P transformations. Alum reduced water-soluble colorimetrically reactive phosphorus (RP) from soils amended with manure more effectively than in soils amended with KHPO. Alum addition lowered Mehlich-3 RP in soils with CMFR but had no influence on Mehlich-3 RP in CMIF- or KHPO-amended soils. A comparison of P in digested Mehlich-3 extracts with RP in undigested samples showed significantly increased P in digests of alum-treated CMFR only. Fractionation data indicated that alum treatment increased P in the NHF-RP (Al-P) fraction only in soils with KHPO, but not in soils with manure treatments. Furthermore, NaOH-extracted nonreactive P was markedly higher in soil with alum-treated CMFR relative to normal CMFR. The CMFR manure was assumed to contain higher concentrations of organic P because these chickens were fed grains only. These results suggest that the formation of alum-organic P complexes may reduce P solubility. By comparing alum-treated KHPO and manures, it appears that organic matter in manure could interfere with the formation of Al-PO complexes.

    Aluminium hydroxide (alum), the most widely used adjuvant in human and animal vaccines, has long been known to promote T helper type 2 (Th2) responses and Th2-associated humoral responses, but the mechanisms have remained poorly understood. In this study, we explored whether alum is able to directly modulate antigen-presenting cells to enhance their potency for Th2 polarization. We found that alum treatment of dendritic cells failed to show any Th2-promoting activities. In contrast, alum was able to enhance the capacity of basophils to induce Th2 cells. When basophils from interleukin-4 (IL-4) knockout mice were examined, the intrinsic Th2-promoting activities by basophils were largely abrogated, but the alum-enhanced Th2-promoting activities on basophils were still detectable. More importantly, Th2-promoting adjuvant activities by alum found in IL-4 knockout mice were also largely reduced when basophils were depleted by antibody administration. Therefore, basophils can mediate Th2-promoting activities by alum both in vitro and in vivo through IL-4-independent mechanisms. Further studies revealed that secreted soluble molecules from alum-treated basophils were able to confer the Th2-promoting activities, and neutralization of thymic stromal lymphopoietin or IL-25 attenuated the IL-4-independent development of Th2 cells elicited by alum-treated basophils. Finally, alum was able to activate NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome in murine basophils in the same way as alum in professional antigen-presenting cells, but NLRP3 was not required for Th2-promoting activities on basophils by alum in vitro. These results demonstrated that alum can enhance the capacities of basophils to polarize Th2 cells via IL-4- and NLRP3-independent pathways. © 2016 John Wiley & Sons Ltd.

    The efficiency of various polyaluminium chloride coagulants (PACls) was compared to the efficiency of aluminium sulfate (alum) in the coagulation-flocculation process preceding direct filtration in drinking water treatment. The comparative study consisted of two separate yet complementary series of experiments: the first series included short (5-7 h) and long (24 h) filter runs conducted at a pilot filtration plant equipped with large filter columns that simulated full-scale filters. Partially treated surface water from the Sea of Galilee, characterized by very low turbidity (-1 NTU), was used. In the second series of experiments, speciation of aluminium in situ was investigated using the ferron assay method. Results from the pilot-scale study indicate that most PACls were as or more efficient a coagulant as alum for direct filtration of surface water without requiring acid addition for pH adjustment and subsequent base addition for re-stabilizing the water. Consequently, cost analysis of the chemicals needed for the process showed that treatment with PACl would be significantly less costly than treatment with alum. The aluminium speciation experiments revealed that the performance of the coagulant is more influenced by the species present during the coagulation process than those present in the original reagents.

    Shale gas is mainly produced from thermally mature black shales. However, biogenic methane also represents a resource which is often underestimated. Today biogenic methane is being produced from the Upper Devonian Antrim Shale in the Michigan Basin which was the most successfully exploited shale gas system during the 1990-2000 decade in the U.S.A. before significant gas production from the Barnett Shale started (Curtis et al., 2008). The Cambro-Ordovician Alum Shale in northern Europe has thermal maturities ranging from overmature in southern areas (Denmark and southern Sweden) to immature conditions (central Sweden). Biogenic methane is recorded during drilling in central Sweden. The immature Alum Shale in central Sweden has total organic carbon (TOC) contents up to 20 wt%. The hydrogen index HI ranges from 380 to 560 mgHC/gTOC at very low oxygen index (OI) values of around 4 mg CO{sub 2}/gTOC, Tmax ranges between 420 - 430 C. The organic matter is highly porous. In general, the Alum Shale is a dense shale with intercalated sandy beds which may be dense due to carbonate cementation. Secondary porosity is created in some sandy beds due to feldspar dissolution and these beds serve as gas conduits. Methane production rates with shale as substrate in the laboratory are dependent on the kind of hydrocarbon-degrading microbial enrichment cultures used in the incubation experiments, ranging from 10-620 nmol/(g*d). In these experiments, the CO{sub 2} production rate was always higher than for methane. Like the northern part of North America, also Northern European has been covered by glaciers during the Pleistocene and similar geological processes may have developed leading to biogenic shale gas formation. For the Antrim Shale one hypothesis suggests that fresh waters, recharged from Pleistocene glaciation and modern precipitation, suppressed basinal brine salinity along the northern margins of the Michigan Basin to greater depths and thereby enhancing methanogenesis

    2013-12-01

    This essay examines three medieval pharmaceutical treatises purportedly authored by Yūhannā ibn Māsawayh (anglicized to John Mesue) and traces their immense influence on the development of pharmacy in early modem Europe and the Hispanic world. Despite the importance of these works throughout the early modern period, Mesue is relatively unknown in the history of pharmacy and medicine, and his exact identity remains unclear. This essay argues that "Mesue" was most likely a pseudonym used by an unknown author of the Latin West and that the three works were crafted to meet the demands of the developing "medical marketplace" of late thirteenth-century Europe, where the manuscripts first appeared. At the same time, however, as the Arabic reference of the pseudonym suggests, these treatises were clearly products of the medieval Islamic world, including many innovations that would provide the basis for the theory and practice of pharmacy for centuries and arguably formed part of the artisanal epistemological influence on the Scientific Revolution.

Urine samples were collected weekly to evaluate proteinuria. Blood samples were collected before every injection, at 21 weeks of age, and at death to evaluate levels of anti-PTX3 and anti-dsDNA. Proteinuria free survival and survival rates were analyzed by the Kaplan-Meier method using Mantel-Cox’s test for comparisons. CFA-treated mice developed both anti-dsDNA antibodies and proteinuria earlier and at higher levels than alumtreated and PBS-injected mice, starting from 13 weeks of age. Proteinuria free survival rates (proteinuria ≥300 mg/dL and survival rates were lower in CFA-treated mice than those treated with alum or injected with PBS (P<0.001 for all. No difference was observed between the alum-treated group and PBS-injected mice. Notably, groups 4 and 5, immunized with PTX3, developed anti-PTX3 antibodies and no significant difference was observed. Alum seems to be as effective as and safer than CFA as adjuvant, since it did not affect disease progression in immunized NZB/NZWF1 mice.

    Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products, which are potentially harmful to human health. This study aimed to quantify total organic carbon (TOC) and total inorganic C losses in runoff after application of dairy slurry, pig slurry, or milk house wash water (MWW) to land and to mitigate these losses through coamendment of the slurries with zeolite (2.36-3.35 mm clinoptilolite) and liquid polyaluminum chloride (PAC) (10% AlO) for dairy and pig slurries or liquid aluminum sulfate (alum) (8% AlO) for MWW. Four treatments under repeated 30-min simulated rainfall events (9.6 mm h) were examined in a laboratory study using grassed soil runoff boxes (0.225 m wide, 1 m long; 10% slope): control soil, unamended slurries, PAC-amended dairy and pig slurries (13.3 and 11.7 kg t, respectively), alum-amended MWW (3.2 kg t), combined zeolite and PAC-amended dairy (160 and 13.3 kg t zeolite and PAC, respectively) and pig slurries (158 and 11.7 kg t zeolite and PAC, respectively), and combined zeolite and alum-amended MWW (72 and 3.2 kg t zeolite and alum, respectively). The unamended and amended slurries were applied at net rates of 31, 34, and 50 t ha for pig and dairy slurries and MWW, respectively. Significant reductions of TOC in runoff compared with unamended slurries were measured for PAC-amended dairy and pig slurries (52 and 56%, respectively) but not for alum-amended MWW. Dual zeolite and alum-amended MWW significantly reduced TOC in runoff compared with alum amendment only. We conclude that use of PAC-amended dairy and pig slurries and dual zeolite and alum-amended MWW, although effective, may not be economically viable to reduce TOC losses from organic slurries given the relatively low amounts of TOC measured in runoff from unamended slurries compared with the amounts applied.

    A prospective study was done to evaluate the efficacy and safety of intravesical instillation of 1% alum solution in 12 cases of hematuria of vesical origin, uncontrolled by saline irrigation for 24 hours via a 3-way Foley catheter. There were 10 cases of transitional cell carcinoma and 2 of radiation cystitis. Complete response was noted in 6 patients and a partial response in 4. Local side effects included suprapubic pain and vesical tenesmus, which were controlled by antispasmodic and/or analgesic drugs. Transient low grade pyrexia (maximum up to 38.2C) was noted in 4 patients. Among the other various clinical and biochemical parameters, serum aluminum level and prothrombin time showed statistically highly significant changes. Serum aluminum increased from an average baseline value of 1.68 to 3.36 mumol./l. without clinical evidence of aluminum toxicity and with levels well below the recommended safe limit. Prothrombin time increased parallel with the increase in serum aluminum level to a maximum of 1 1/2 times the control. Prothrombin values, therefore, can be used clinically, since they are readily obtainable whereas serum aluminum levels are not. Vesical irrigation with 1% alum solution is a safe method to control hematuria of vesical origin in properly selected cases.

    Full Text Available A phase II clinical trial with glutamic acid decarboxylase (GAD 65 formulated with aluminium hydroxide (GAD-alum has shown efficacy in preserving residual insulin secretion in children and adolescents with recent-onset type 1 diabetes (T1D. We have performed a 4-year follow-up study of 59 of the original 70 patients to investigate long-term cellular and humoral immune responses after GAD-alum-treatment. Peripheral blood mononuclear cells (PBMC were stimulated in vitro with GAD(65. Frequencies of naïve, central and effector memory CD4+ and CD8+ T cells were measured, together with cytokine secretion, proliferation, gene expression and serum GAD(65 autoantibody (GADA levels. We here show that GAD-alum-treated patients display increased memory T-cell frequencies and prompt T-cell activation upon in vitro stimulation with GAD(65, but not with control antigens, compared with placebo subjects. GAD(65-induced T-cell activation was accompanied by secretion of T helper (Th 1, Th2 and T regulatory cytokines and by induction of T-cell inhibitory pathways. Moreover, post-treatment serum GADA titres remained persistently increased in the GAD-alum arm, but did not inhibit GAD(65 enzymatic activity. In conclusion, memory T- and B-cell responses persist 4 years after GAD-alum-treatment. In parallel to a GAD(65-induced T-cell activation, our results show induction of T-cell inhibitory pathways important for regulating the GAD(65 immunity.

    Full Text Available The lazy and expired reagents are among the dangerous waste generated in Cuba, some of which contain heavy metals. These substances accumulate without a final disposition, neither appropriate use, with the purpose of not contaminating the environment. In such a sense, the authors propose an alternative use for alum of chromium (III and potassium, when transforming it into oxide by precipitation with alkalis to apply it as ceramic pigment. The present paper shows the use tests and the determination of purity by oxidation-reduction titration; giving it a final disposition without any environmental risk and with the additional creation of economic values starting from immobilized resources, bringing about the substitution of import pigments, which are quite expensive.

    The thermal dehydrations of potash alum caused by heating at various temperatures for at least 2 h were investigated by ex situ Raman spectroscopy and X-ray diffraction (XRD) analyses in air. With increasing the heating temperature, all Raman peaks were observed to broaden, while an additional broad peak appeared at approximately 1030 cm{sup −1} and shifted toward higher wavenumbers. In addition, the Raman band assigned to the O–H stretching mode weakened. The orientational disorder (OD) of the sulfate ions, as indicated by the intensity ratio of doublet peaks at 989 and 974 cm{sup −1}, was found to increase with increasing the heating temperature. The XRD patterns demonstrated that a structural phase transition from crystalline KAl(SO{sub 4}){sub 2}⋅12H{sub 2}O to amorphous phases began at around 75 °C, while broadening of the Raman peaks and an increase in OD also suggested the onset of an amorphous phase. Raman peaks corresponding to anhydrous KAl(SO{sub 4}){sub 2} appeared at approximately 180 °C. It was concluded that the elimination of water molecules was responsible for increase in the extent of OD, and this in turn induced the observed phase transitions. The formation of the amorphous phases observed in this work was similar to the pressure-induced amorphization of KAl(SO{sub 4}){sub 2}⋅12H{sub 2}O. - Highlights: • The thermal dehydration of potash alum proceeds through several steps. • Raman spectra and X-ray diffraction reveal the amorphization of the heated samples. • A transition from the amorphous phase to the KAl(SO{sub 4}){sub 2} crystal phase is observed in the sample heated at 180 °C.

    A good understanding of cementation is critical for reservoir quality predictions. However, studies of core material have shown that cementation may be driven by variations in pore size of the host rock. To better understand the underlying process, we developed a transparent microreactor for diffusion-controlled cementation experiments under the microscope. We studied the effect of different pore sizes and surface charges of solid material at different pH, using rock analogs. High-resolution videos allowed to analyze the nucleation from solution, pore cementation and growth rates of cements. Diffusion - considered the major mass transport during burial diagenesis - was driven along a temperature gradient across the microreactor. Pores were cemented with salt, which is well known to form pore-size dependent seals in silicilastic reservoirs. While halite precipitated primarily in pores bigger than 200 {mu}m, alum nucleated in smaller pores. The growth rate of alum (10{sup -5} mm/s) was one order of magnitude higher than that of halite. However, the dissolution rates of both minerals was similar at about 10{sup -6} mm/s. Authigenic euhdral halite migrated against the bulk diffusion transport and towards the higher-temperature reservoir. Halite growth rates increased by one order of magnitude to 1.8 x 10{sup -5} mm/s, if the phase boundary was vapor-liquid. A comparison nucleation in a 2-phase porous rock analog showed no difference in cementation pattern at a pH 7. However, at a pH of 10.5 the surface energies of the two different solids are altered, and porosity was reduced 60% more by cements in the phase-1 porous layers. Our experiments showed that pore size dependent nucleation and cementation is a process, which may also take place in complex reservoirs. With the successful pore clogging of halite we can now bring our experimental setup to reservoir conditions and establish the processes at elevated p-T conditions. (orig.)

    Full Text Available Background: The refining process generates large volumes of wastewater containing a variety of chemical contaminants. The use of natural substitutes in treating wastewater which have fewer harmful effects is considered an effective step towards protecting the environment and sustaining the development of these industries. This study focused on the use of Moringa oleifera and alum at the Wastewater Unit at Bandar Abbas Refinery. Methods: This study was performed in 2014 in a laboratory using jar apparatus. These experiments were conducted in batch system and effective parameters including pH, coagulant dose and contact time were investigated on the wastewater obtained from Bandar Abbas Oil Refinery. Results: The jar test experiment showed that M. oleifera at 70 mg/L, optimum temperature, pH, and mixing speed could remove 38.60% of chemical oxygen demand (COD, 63.70% of turbidity, and 62.05% of total suspended solids (TSS. Also, alum at 40 mg/L removed COD, turbidity, and TSS by 51.72%, 92.16%, and 85.26% respectively from the refinery wastewater. Moreover, when M. oleifera and alum was used together with a 2:1 dosage ratio (alum at 80 mg/L and M. oleifera at 70 mg/L, they will remove COD, turbidity, and TSS by up to 50.41%, 86.14%, and 81.52% respectively. Conclusion: The use of M. oleifera as a natural coagulant is important in treating refinery wastewater not only from an environmental but also an economic point of view.

  16. The Jahn-Teller effect and its observation in titanium alum

    1996-01-01

    Full text: A fundamental assumption, often employed to problems in solid state physics, is that a system may be well described within the confines of the Born-Oppenheimer approximation. As a consequence of the substantial difference of masses, the electrons are assumed to follow the motion of the nuclei adiabatically; hence, the motion of the electrons and nuclei are solved separately. As Jahn and Teller showed in 1936, any non-linear molecule having orbital degeneracy will be unstable to at least one asymmetric displacement which lifts the degeneracy. The wave equation must then be solved taking into account coupling between the electronic and nuclear motion. The E x β system, an electronic doublet coupled to a single mode of vibration, is introduced as an elementary example and is used to illustrate features characteristic of Jahn-Teller systems. The E x ε system is discussed in conjunction with work currently being undertaken on CsTi(SO 4 ) 2 .12H 2 O. In this alum, the [Ti(OH 2 ) 6 ] 3 + cation (3d 1 ) is subject to an axial field which acts to leave a doubly degenerate electronic ground term. Spectroscopic and crystallographic data show the salt to undergo a phase transition at 12 K which we associate with a Co-operative Jahn-Teller Effect manifested by the interaction of the Jahn-Teller electrons with the crystal lattice. Also presented are EPR and SQUID data which illustrate how the Jahn-Teller effect leads to quenching of orbital angular momentum and spin-orbit coupling

    Full Text Available O presente artigo procura discutir a produção de alumínio no Brasil e seus impactos socioambientais e à saúde pública. Os impactos da cadeia produtiva do alumínio colocam em xeque a ideia de crescimento sustentável difundido pelos grupos empresariais que atuam no setor. O artigo defende a tese de que a inserção do Brasil no mercado global do alumínio faz parte de uma nova configuração da Divisão Internacional do Trabalho (DIT, cujas atividades econômicas poluentes e altamente dependentes de energia, como o caso deste metal vêm se deslocando para nações periféricas ou emergentes, onde muitas vezes as legislações são menos austeras, do mesmo modo como são menos influentes os movimentos ambientalistas e as reivindicações das populações atingidas nos territórios afetados em seus direitos à saúde, ao ambiente saudável e à cultura. A competitividade desta commodity é garantida no mercado internacional, a partir da produção de externalidades como os danos ao ambiente, desmatamentos, emissões de gases do efeito estufa e de cenários de injustiça ambiental, como também nos empreendimentos de construção de barragens hidrelétricas que expõem comunidades tradicionais a situações que envolvem a perca de seus territórios.

    Full Text Available Objetivou-se, com este trabalho, identificar indicadores de resistência à toxicidade de alumínio em arroz de terras altas e linhagens com baixa susceptibilidade a esta toxicidade. Avaliaram-se 48 linhagens de arroz em solução nutritiva e dois níveis de estresse de alumínio: 0 e 40 mg dm-3 de Al; após 21 dias de teste, estimaram-se a massa da matéria seca das raízes e do dossel, o comprimento máximo das raízes e a altura das plantas e, também, índices de susceptibilidade à toxicidade de alumínio. Verificou-se que todos os indicadores de susceptibilidade ao alumínio, exceto aqueles relacionados à variabilidade do pH, se correlacionaram significativamente. O índice de susceptibilidade do crescimento radicular (S Rcm por se considerar, no seu cálculo, o crescimento radicular com e sem estresse de Al e a pressão de estresse de Al em que as linhagens foram avaliadas, constitui-se em importante parâmetro a ser usado na seleção para resistência à toxicidade ao alumínio. Conforme a distribuição das linhagens em quartis, delimitados pelo comprimento radicular superior a 47 cm e pelo SRcm menor que 0,92, selecionou-se o grupo de linhagens, CNA4120, CNA4164 e CNA1383, que apresenta raízes bem desenvolvidas, tanto na ausência como na presença de alumínio.The objective of this work was to identify indicators of resistance of aluminum toxicity in upland rice as well as lines with low susceptibility to this toxicity. Fifty one rice lines were evaluated in greenhouse, in nutrient solution, under two levels: 0 and 40 mg dm-3 of Al. Data of dry weight of roots and aerial parts, length of roots and plant height were obtained 21 days later. Also, the index of susceptibility to aluminum toxicity was calculated. The results showed significant correlation between all indicators with each other, except to those related to pH variability. Since root length susceptibility index (S Rcm was calculated taking into consideration the root

    Full Text Available Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM to reduce the formation of disinfection by-products (DBPs, is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the effectiveness of alum and ferric chloride in removing DBPs precursors from eight synthetic water samples, each representing a different element of the USEPA’s 3×3 enhanced coagulation matrix. The effect of enhanced coagulation on the residual metal (aluminum/iron concentration in the treated water was assessed as well. The removal of total organic carbon (TOC was dependent on the coagulant type and was enhanced with increasing coagulant dose, but the latter had no further considerable effect in case of increasing to high levels. For all the treated samples coagulation with ferric chloride proved to be more effective than alum at similar doses and the mean values of treatment efficiencies were 51% and 32% for ferric chloride and alum, respectively. Ferric chloride was therefore considered the better chemical for enhancing the coagulation process. Besides, due to less production of sludge by this coagulant, it would be predicted that treatment plants would be confronted to fewer problems with respect to final sludge disposal. Measurements of residual metal in treated water indicated that iron and aluminum concentrations had been increased as expected but the quality of water concerning the residual metal deteriorated much more in cases of under-dosing. Despite expecting high residual Al and Fe concentrations under enhanced coagulation, metal concentrations were frequently remained low and were not increased appreciably.

    Previously, we reported the ability of the chimeric protein DIIIC-2 (domain III of the dengue envelope protein fused to the capsid protein of dengue-2 virus), to induce immunity and protection in mice, when it is highly aggregated with a non-defined oligodeoxynucleotide (ODN) and adjuvanted in alum. In this work, three different defined ODNs were studied as aggregating agents. Our results suggest that the nature of the ODN influences the capacity of protein DIIIC-2 to activate cell-mediated immunity in mice. Consequently, the ODN 39M was selected to perform further experiments in mice and nonhuman primates. Mice receiving the preparation 39M-DIIIC-2 were solidly protected against dengue virus (DENV) challenge. Moreover, monkeys immunized with the same preparation developed neutralizing antibodies, as measured by four different neutralization tests varying the virus strains and the cell lines used. Two of the immunized monkeys were completely protected against challenge, whereas the third animal had a single day of low-titer viremia. This is the first work describing the induction of short-term protection in monkeys by a formulation that is suitable for human use combining a recombinant protein from DENV with alum.

    The application of pulsed mode ultrasound (PMU) as a pre-treatment for alum coagulation was investigated at various alum dosages and pH levels. The effects of the treatments on turbidity and dissolved organic carbon (DOC) removal and residual Al were evaluated. Response surface methodology (RSM) was utilized to optimize the operating conditions of the applied treatments. The results showed that PMU pre-treatment increased turbidity and DOC removal percentages from maximum of 96.6% and 43% to 98.8% and 52%, respectively. It also helped decrease the minimum residual Al from 0.100 to 0.094 ppm. The multiple response optimization was carried out using the desirability function. A desirability value of >0.97 estimated respective turbidity removal, DOC removal and Al residual of 89.24%, 45.66% and ∼ 0.1 ppm for coagulation (control) and 90.61%, >55% and ∼ 0 for coagulation preceded by PMU. These figures were validated via confirmatory experiments. PMU pre-treatment increased total coliform removal from 80% to >98% and decreased trihalomethane formation potential (THMFP) from 250 to 200 ppb CH3Cl. Additionally, PMU application prior to coagulation improved the settleability of sludge due to the degassing effects. The results of this study confirms that PMU pre-treatment can significantly improve coagulation performance. Copyright © 2015 Elsevier B.V. All rights reserved.

  3. Impacts of alum residues from Morton Jaffray Water Works on water quality and fish, Harare, Zimbabwe

    Science.gov (United States)

    Muisa, Norah; Hoko, Zvikomborero; Chifamba, Portia

    campaigns (ANOVA: p pollution from the water works residues was higher than all the other sources in the catchment. Aluminium levels were generally in the order of; sediments > fish > water. Bioaccumulation occurred in the fish and the order of bioconcentration was; kidney > liver > gill > muscle. The amounts of aluminium in the fish tissues investigated were significantly higher (maximum = 2.92 mg/g) than was reported in other studies reviewed (maximum = 0.18 mg/g). Thus, the water treatment plant residues are greatly increasing the concentrations of aluminium in the water system downstream of the plant thus creating a great risk of aluminium toxicity for fish. Treatment of the residues before discharge, substitution of alum with other coagulants, and re-use of the residues in buffer strips, agricultural lands and in sewage works should be considered.

    This study was conducted by author as a member of Specialty Chemical Division of Sitara Chemical Industries which is the largest chlor -alkali manufacturing industry in Pakistan. Sitara is also producing FeCl/sub 3/ as a byproduct to consume its additional quantity of chlorine produced during electrolysis of brine solution for caustic soda preparation. Most of the industries are using Alum along with other polymers for treatment of effluent waste water. Treatment system is based on sand bed filters. For coagulation of unwanted materials present in the water, Alum is being used with Anionic Polymer (Accofloc-A2125) as flocculent. But the ferric chloride is not only functions as a reactants to remove water impurities but it also functions as a both coagulant and a Flocculent. This study was conducted for finding best alternative chemicals to improve treated water quality. For this purpose Ferric Chloride (FeCl/sub 3/) is used as best alternative of alum for better removal of turbidity, heavy metals and micro organisms to eradicate above said problems and for better removal of turbidity, heavy metals and micro, organisms to eradicate health problems. As per lab scale results quality of treated water with Ferric Chloride (FeCl/sub 3/) proved better than that of Alum. The main objective of this research is to investigate the efficiency of coagulation and flocculation processes for removing suspended solids, colour and COD which present in significant quantity. Three types of coagulants were examined using standard jar test apparatus, i.e., aluminum sulphate (alum), ferric chloride (FeCl/sub 3/) and ferrous sulphate (FeSO/sub 4/). The effects of agitation speed, settling time, pH, coagulant dosages and temperature were examined. At 300 rpm of rapid mixing and 50 rpm of slow mixing and 60 minutes settling time, higher removals of suspended solids (over 95%), colour (90%) and COD (43%) were achieved at pH 4 and 12. FeCl/sub 3/ was found to be superior compared with other

A análise do metal foi realizada em espectrômetro de emissão atômica com plasma indutivamente acoplado. Os resultados demonstraram transferência desprezível do Al para alguns alimentos, sendo que a maior transferência ocorreu no preparo de molho de tomate (baixo valor de pH, na panela sem revestimento. Um cardápio preparado com todos esses alimentos para as duas refeições diárias, mostrou que a massa de Al incorporada pelo alimento corresponde a 2% do limite de ingestão diária de Al (1 mg.kg -1 de peso corporal/dia, considerando-se um indivíduo de 60 kg. Assim, conclui-se que o uso de panelas de alumínio no preparo de alimentos praticamente não interfere na ingestão total do elemento para o ser humano.Aluminum is associated with neurological diseases, such as Alzheimer by some authors. Although this has never been confirmed, there is evidence of an accumulation in kidneys of people with renal problems. This present work was carried out to address this subject by evaluating the occurrence of significant aluminum migration from cooking utensils during food preparation. Eight types of food cooked in different ways and three distinct types of pans (a saucepan, pressure cooker and frying pan, with and without teflon coating, were evaluated. The metal analysis was conducted in an Optical Emission Spectrometer with Inductively Coupled Plasma. The results showed insignificant transference of aluminum in some

    Full Text Available O objetivo deste trabalho foi avaliar diferentes métodos de extração e quantificação de alumínio trocável em Organossolos. As amostras foram coletadas em três perfis de turfeira e, então, secas ao ar e passadas em peneira de malha de 2 mm. Foram feitas extrações com KCl 1 mol L-1 , Ca(OAc2 1 mol L-1 e CuCl2 0,5 mol L-1 . Em seguida, os extratos obtidos por KCl e Ca(OAc2 foram analisados por titulação com NaOH 0,025 mol L-1 e por espectrômetro de absorção atômica com forno de grafite (GF-AAE. Os extratos obtidos por CuCl2 foram analisados por GF-AAE. Na quantificação por GF-AAE, os extratores KCl e Ca(OAc2 tiveram capacidade semelhante de extrair alumínio trocável, enquanto o CuCl2 foi capaz de extrair também o Al reativo. Os elevados teores de alumínio trocável observados na titulação após extração com KCl podem estar relacionados aos elevados teores do íon H+ presente nas amostras. O método indicado para determinação do teor de alumínio trocável em Organossolos é a extração com KCl ou com Ca(OAc2 e, para quantificação, a espectrofotometria de absorção atômica com forno de grafite.

    Full Text Available GAD-alum given into lymph nodes to type 1 diabetes patients participating in an open-label pilot trial resulted in preservation of C-peptide similar to promising results from other trials. Here, we compared the immunomodulatory effect of giving GAD-alum directly into lymph nodes versus that induced by subcutaneous administration. Samples from T1D patients (n=6 who received 4 μg GAD-alum into lymph nodes (LNs, followed by two booster injections one month apart, and from patients (n=6 who received two subcutaneous injections (SC (20 μg given one month apart were compared. GADA, IA-2A, GADA subclasses, IgE, GAD65-induced cytokines, PBMC proliferation, and T cell markers were analyzed. Lower doses of GAD-alum into LN induced higher GADA levels than SC injections and reduced proliferation and IgG1 GADA subclass, while enhancing IgG2, IgG3, and IgG4. The cytokine profile was dominated by the Th2-associated cytokine IL-13, and GAD65 stimulation induced activated CD4 T cells. Patients responding clinically best account for most of the immunological changes. In contrast, SC treatment resulted in predominant IgG1, predominant IFN-γ, higher proliferation, and activated CD4 and CD8 cells. Patients from the LN group with best metabolic outcome seemed to have common immune correlates related to the treatment. This trial is registered with DIAGNODE (NCT02352974, clinicaltrials.gov and DIABGAD (NCT01785108, clinicaltrials.gov.

    Full Text Available Um método rápido e sensível espectrofotométrico de determinação do sistema alumínio-hematoxilina pode ser usado para se conhecer o teor de alumínio em tecidos de plantas. Êste trabalho descreve o método analítico com modificações introduzidos, estuda as interferências e inclui sua adaptação para plantas. Depois do incineração do material orgânico, o alumínio é dosado usualmente numa alíquota do extrato de cinzas equivalente a 0,005 a 0,020 g de material sêco. A côr é obtida em condições controladas de pH com solução buffer de acetato e alcalinização com carbonato de amônio. No processo podem ser determinadas, rapidamente, pequenas quantidades de alumínio, sem interferência de outros elementos, nos concentrações que usualmente ocorrem nas plantas.A procedure is described for the spectrophotometric determination of aluminum in ash extracts of plant tissue using the organic dye hematoxylin, without removal of iron. It has been devised by modifying and incorporating previously published procedures for water and uranium materials. The proposed method provides a rapid determination of small amounts of aluminum up to 5 micrograms, with a recovery error smaller than ±5 per cent, as tested for several plant materials. Manganese, copper, molybdenum, vanadium, cobalt, and chromium in quantities usually encountered in plant tissue do not interfere with the method.

    The Cambrian Alum Shale Formation in the Andrarum-3 core from Scania, southern Sweden, consists of black siliciclastic mudstone with minor carbonate intercalations. Four facies comprise three siliciclastic mudstones and one fine-grained carbonate. The facies reflect deposition along a transect from deep ramp to basin on a Cambrian shelf. The three mudstone facies contain abundant clay clasts and laterally variable siltstone laminae. Bed-load transport processes seem to have dominated deposition on this deep shelf. These sedimentary rocks record mainly event deposition, and only relatively few, thin laminae probably resulted from suspension settling. The Alum Shale Formation deep shelf did not show a bioturbation gradient, but fecal strings are common and Planolites burrows are rare in all mudstone facies. Evidence for biotic colonization indicates that this mudstone environment was not persistently anoxic, but rather was most likely intermittently dysoxic. The Alum Shale Formation in the Andrarum-3 core shows an overall decrease of grain size, preserved energy indicators, and carbonate content upsection interpreted to reflect a deepening upward. The succession can also be divided into four small-scale fining-upward cycles that represent deepening, and four overlying coarsening-upward cycles that represent upward shallowing.

    Full Text Available Durante 110 dias, realizou-se um experimento em solução nutritiva, para avaliar os efeitos do alumínio nas concentrações de 0, 5, 10, 15, 20 e 25 mg L-1, em pH 4,0, sobre o crescimento de mudas de goiabeira, absorção e acumulação de macronutrientes e de Cu, Fe, Mn, Zn e Al. Os sintomas visuais de fitotoxidez, associados às doses 20 e 25 mg L-1 de Al, foram caracterizados pela menor altura das plantas, ausência de ramificação, menor diâmetro do caule e raízes mais escuras; as folhas apresentaram dimensões menores e pecíolos avermelhados. Em doses relativamente baixas, o alumínio promoveu resposta positiva de crescimento, porém, em doses altas, os teores de macronutrientes e de Fe, Mn e Zn nas folhas de diagnose (3º e 4º pares a partir do ápice, bem como o conteúdo mineral nas diversas partes da planta, foram influenciados pelas doses de alumínio. A fitotoxidez afetou, mais acentuadamente, os teores de P, Ca, Mg, Mn e Zn. Cerca de 95% do Al absorvido concentrou-se nas raízes.

    A model simulating the effluent nitrogen (N) concentration of treated animal farm wastewater in a pilot on-site constructed wetland (CW) system, using dewatered alum sludge cake (DASC) as wetland substrate, is presented. The N-model was developed based on the Structural Thinking Experiential Learning Laboratory with Animation software and is considering organic nitrogen, ammonia nitrogen (NH3) and nitrate nitrogen (NO3-N) as the major forms of nitrogen involved in the transformation chains. Ammonification (AMM), ammonia volatilization, nitrification (NIT), denitrification, plant uptake, plant decaying and uptake of inorganic nitrogen by algae and bacteria were considered in this model. pH, dissolved oxygen, temperature, precipitation, solar radiation and nitrogen concentrations were considered as forcing functions in the model. The model was calibrated by observed data with a reasonable agreement prior to its applications. The simulated effluent detritus nitrogen, NH4-N, NO3-N and TN had a considerably good agreement with the observed results. The mass balance analysis shows that NIT accounts for 65.60%, adsorption (ad) (11.90%), AMM (8.90%) followed by NH4-N (Plants) (5.90%) and NO3-N (Plants) (4.40%). The TN removal was found 52% of the total influent TN in the CW. This study suggested an improved overall performance of a DASC-based CW and efficient N removal from wastewater.

    Jack Connor, Jim Hastie and Bryan Taylor The Hannes Alfvén Prize of the European Physical Society for Outstanding Contributions to Plasma Physics (2004) has been awarded to Jack Connor, Jim Hastie and Bryan Taylor `for their seminal contributions to a wide range of issues of fundamental importance to the success of magnetic confinement fusion, including: the development of gyro-kinetic theory; the prediction of the bootstrap current; dimensionless scaling laws; pressure-limiting instabilities, and micro-stability and transport theory'. Jack Connor, Jim Hastie and Bryan Taylor form one of the most successful teams of theoretical physicists in the history of magnetic confinement fusion. They have made important contributions individually, but their greatest discoveries have mostly been accomplished jointly, either in pairs or as a team involving all three. Their early work, in the 1960s, included the development of the gyro-kinetic theory for fine-scale plasma instabilities, which today forms the basis of the most advanced turbulence simulation codes in tokamak and stellarator research. The theoretical prediction of the bootstrap current, made in 1970-71 was not confirmed experimentally for over a decade but is now regarded as crucial to the success of the tokamak as a steady-state fusion power source. Their work on collisional transport also included the prediction of impurity ion accumulation, which is observed in internal transport barriers and is a key concern for long-pulse tokamak operation. The relativistic threshold for runaway electrons, identified in 1975, forms the basis of the most recent tokamak disruption mitigation schemes. In the late 1970s, the team developed the theory for ballooning instabilities, which provided an important ingredient in the `Troyon-Sykes' β-limit—an expression that is still used as a guide to the performance of tokamaks and in the design of ITER. Ballooning mode theory has also contributed to the understanding of

    Full Text Available A presença de alumínio (Al reduz o rendimento em solos ácidos ou em áreas onde o subsolo possui pH abaixo de 5, pois limita o crescimento radicular e, consequentemente, a absorção de água e nutrientes. Genótipos elite de aveia (Avena sativa L. não selecionados para a tolerância ao Al foram avaliados quanto a essa característica em solução nutritiva. Foi utilizada, como parâmetro de comparação da tolerância ao Al, a média de recrescimento radicular após a exposição ao Al. O recrescimento da raiz principal dos genótipos elite foi comparado com os controles UFRGS17, considerado tolerante e UFRGS930598-6, sensível. Foram avaliadas as linhagens UFRGS057005-1 e UFRGS057022-2, e as cultivares comerciais 'URSGuria', 'URSTorena', 'URSPenca', 'URSGuará', 'URS Charrua', 'URSTarimba', 'URSTaura', 'URSGuapa' e 'URS21'. A amplitude de recrescimento da raiz dentro de cada genótipo foi elevada, sendo a menor de 15mm e a maior de 44mm. As cultivares 'URSCharrua' e 'URSGuapa' demonstraram tolerância superior a 'UFRGS17'. URSTarimba, apesar da média similar a UFRGS17, mostrou distribuição de frequência mais positiva. URSTorena, UFRGS0570005-1 e URSPenca classificaram-se como intermediários, sendo inferiores a UFRGS17. Nenhum dos genótipos elite apresentou médias de recrescimento igual ou inferior às obtidas pelo controle sensível, UFRGS930598-6.

    Full Text Available A aveia branca (Avena sativa L. é uma cultura que tem um papel importante no sistema de produção de grãos e integração lavoura-pecuária, no entanto, em algumas regiões brasileiras, o pleno estabelecimento e desenvolvimento dessa cultura, bem como o aumento de produtividade são inviabilizados pelo excesso de alumínio (Al nos solos. A avaliação de caracteres de plântulas de aveia desenvolvidas sob cultivo hidropônico com adoção de solução nutritiva mínima pode ser eficiente para classificar genótipos sensíveis e tolerantes ao Al. Este trabalho objetivou avaliar o desempenho de 10 genótipos de aveia submetidos ao estresse por Al, baseando-se na análise da retomada do crescimento da raiz, com uso de solução mínima e identificando quais caracteres se mantêm correlacionados. Foram adotadas diferentes doses de Al (0, 3, 6, e 9 mg L-1 de Al. Com uso de solução mínima, a dose de 6 mg L-1 de Al é a mais adequada na diferenciação de genótipos sensíveis e tolerantes. Dentre os genótipos estudados, UFRGS 14, UFRGS 19 e URS Guapa são os mais tolerantes e UPFA 20, UPF 18 e IAC 7, os mais sensíveis ao Al. Com o objetivo de classificar genótipos de aveia entre sensíveis e tolerantes ao Al, nenhuma outra variável pode ser utilizada em substituição à retomada do crescimento da raiz.

  19. The giant Alum Shale polymetallic deposits of Jämtland, Sweden – A major potential low cost supplier of uranium for the future

    2014-01-01

    Jämtland County in Sweden contains approximately 11% of global uranium resources which are compliant with either the Toronto or Australian Stock Exchange codes. A widespread unit through northern Europe, the Alum Shale host rock has been a historic source of alum, oil and uranium. Exploration for uranium in the 1970s located several tens of square kilometres with the development of relatively thick Alum Shale in Jämtland. The Alum Shale in Jämtland is a fine-grained, carbonaceous schist. The groundmass comprises quartz, feldspar, white micas and carbon. The uranium, molybdenum and vanadium have been shown to be concentrated in the organic/mica matrix. Nickel and zinc are preferentially concentrated within the pyrite grains. Total mineral resources in the district are approximately 5 billion tonnes, at a grade of approximately 136 ppm U (160 ppm U_3O_8). Aura Energy Ltd, one of the holders of permits in the district, has 2.35 BT @ 131 ppm U (155 ppm U_3O_8). The average grades of other metals present in the resource are: molybdenum 207ppm, vanadium 1,519ppm, nickel 316ppm, and zinc 431ppm. These polymetallic resources are exceptionally large, and Aura’s uranium resource constitutes the second largest undeveloped resource anywhere in the world. Black schists are typically considered to be challenging metallurgically. Hence the Alum Shale has been previously considered a potential high cost source of uranium. The primary issue has been the high cost associated with acid reagent to extract the uranium. Recently the pyrite has been recognised as a possible source of acid within the ore itself. Bacterial leaching to catalyse the oxidation of pyrite was demonstrated to be the most effective process for generating this acid. The Jämtland Alum Shales appear ideally suited to bioleaching because of the level of pyrite present, and the lower proportion of acid consuming minerals such as carbonates. Aura Energy has established leach extractions of up to 85% of the

    Herpes Simplex Virus Type 2 (HSV-2) infection can result in life-long recurrent genital disease, asymptomatic virus shedding, and transmission. No vaccine to date has shown significant protection clinically. Here, we used a mouse model of genital HSV-2 infection to test the efficacy of a vaccine consisting of whole, formalin-inactivated HSV-2 (FI-HSV2) formulated with monophosphoryl lipid A (MPL) and alum adjuvants. Vaccine components were administered alone or as a prime-boost immunization together with DNA vaccines encoding a truncated glycoprotein D2 (gD2t) and two conserved HSV-2 genes necessary for virus replication, UL5 (DNA helicase) and UL30 (DNA polymerase). Our results show: (1) compared with mock immunized controls, mice immunized with FI-HSV2 plus MPL/alum consistently showed protection against disease burden and total viral shedding while the mice immunized with gD2t protein with MPL/alum did not; (2) protection against genital disease and viral replication correlated with the type of boost in a prime-boost immunization with little advantage afforded by a DNA prime; (3) intramuscular (i.m.) immunization with FI-HSV2 in MPL/Alhydrogel adjuvant provided nearly complete protection against vaginal HSV-2 shedding after a lethal intravaginal (i.vag.) short-term challenge and long-term rechallenge; (4) single formulation immunization with DNA vaccines, FI-HSV2, and MPL in an aluminum phosphate (Adju-Phos) adjuvant did not increase protection relative to FI-HSV2/MPL/Adju-Phos alone; and (5) addition of MPL/alum to the FI-HSV2 was required for optimal protection against disease, viral replication, and latent virus load in the dorsal root ganglia (DRG). Most notably, an optimized vaccine formulation of FI-HSV2 MPL/Alhydrogel given i.m. completely protected against detectable vaginal HSV-2 shedding in the majority of animals and HSV-2 latent DNA in the DRG of all animals.

    Full Text Available Oxides containing aluminium and barium, optionally with chromium, are refractory with several possible industrial uses. A gel precursor of an oxide having the formula BaO.n(Al2xCr2yO3, where 1Oxidos contendo alumínio e bário, opcionalmente com crômio, são refratários com vários possíveis usos industriais. Foi preparado um gel precursor de um óxido de formula BaO.n(Al2xCr2yO3, com 1alumínio ou uma solução de um sal de alumínio e um sal de cromo III, formando então um gel que é queimado para se obter o óxido desejado. Filamentos podem ser estraídos duramente a formação do gel ou extrudados de um gel semi-rígido. Estudos de infravermelho com transformada de Fourier, difração de raios X e ressonância magnética nuclear com 27AL mostraram que o bário não é incorporado diretamente na estrutura do gel. Oxidos de alumínio e bário foram obtidos somente após liquefação de espécies de bário. Foi preparada uma mistura de pós adequada para queima para se obter um óxido de fórmula BaO.m[Al2x Cr2y O3] com 4,6alumínio e bário. É feito um sumário de trabalhos anteriormente publicados.

    Full Text Available O presente trabalho teve como objetivo avaliar a influência de diferentes níveis de alumínio nos parâmetros biométricos dos porta-enxertos cítricos limoeiro Cravo e citrumeleiro Swingle em cultivo hidropônico. O experimento foi instalado em casa de vegetação em Botucatu, SP. Os tratamentos seguiram o delineamento estatístico inteiramente casualizado, com 3 repetições, em parcelas subdivididas. Os níveis de alumínio utilizados foram: 0; 7,5; 15; 22,5 e 30 mg L-1, na forma de AlCl3 6.H2O em solução nutritiva. Foram avaliados os parâmetros biométricos altura, número de folhas, diâmetro do caule, área foliar, comprimento e volume de raízes. De acordo com os resultados obtidos, conclui-se que o citrumeleiro Swingle apresentou-se mais sensível ao alumínio, sendo que, a partir de 7,5 mg L-1 houve redução nos valores destes parâmetros, enquanto que o limoeiro Cravo mostrou-se mais tolerante aos níveis de alumínio.

    Full Text Available O objetivo deste trabalho foi avaliar os genótipos de soja BR86-5974, BR86-7396, Dourados, Doko RC, EMGOPA 305, IAC-9, BR-9 (Savana, UFV-1, UFV-9 e UFV Araguaia em relação à tolerância ao alumínio (Al em hidroponia e em solo. Na solução com Al foi medido o comprimento radicular. Em solo com 49% de saturação de Al avaliou-se área foliar, altura de planta, altura de inserção da primeira vagem, produção de matéria seca, produção de grãos e índice de colheita. Os genótipos BR86-7396 e IAC-9 são os de maior tolerância ao Al, e UFV-1 mostrou o pior desempenho. Houve correlação significativa entre alongamento radicular e produção de grãos (r = 0,705, área foliar (r = 0,645 e produção de matéria seca (r = 0,634. Isto indica que experimentos em hidroponia e solo são igualmente eficientes na seleção de soja tolerante ao alumínio. A variabilidade detectada sugere que o conjunto de genótipos de soja possui ampla variabilidade genética, o que é desejável em programas de melhoramento com o objetivo de elevar estabilidade de produção no Cerrado.

    Full Text Available O alumínio, em solos ácidos, é um dos principais responsáveis pela baixa produtividade de culturas. O objetivo deste trabalho foi avaliar a variabilidade genética da Brachiaria ruziziensis para a tolerância ao alumínio. Foram utilizados 10 genótipos da espécie referida, crescidas em vasos com 0, 30 e 60 mg/L de alumínio em solução nutritiva. Foi utilizado o delineamento inteiramente casualizado em esquema fatorial, com seis repetições e parcelas de uma planta por vaso. Foram avaliados: a produção de massa verde da parte aérea e raízes (MVPA e MVR, a produção de matéria seca da parte aérea e raízes (MSPA e MSR, o incremento no crescimento da parte aérea e das raízes (IPA e IR, expresso pela diferença entre o crescimento final e o inicial, e o incremento no número de perfilhos (INP. O aumento nas concentrações de alumínio provocou decréscimos para as médias de todas as características avaliadas, excetuando o IR. A ausência de diferenças do genótipo 8 para seis das sete características analisadas, com exceção da MVPA, demonstra ser ela a mais promissora para estudos posteriores em melhoramento, visando maior produtividade em solos ácidos. Os resultados evidenciaram a existência de variabilidade genética entre os genótipos avaliados para a tolerância ao alumínio tóxico, sendo possível identificar materiais mais produtivos na presença desse metal.In acid soils, the aluminum is responsible for the low cultures productivity.

    Full Text Available Este trabalho foi realizado em Piracicaba (SP, em 1995, com o objetivo de investigar a causa da ausência de sintomas de toxidez de alumínio ou da redução de produtividade de plantas cultivadas em um solo Podzólico Vermelho-Amarelo do Acre. O teor de Al trocável nesse solo ultrapassa 14 cmol c dm-3 no horizonte B. Amostras dos horizontes A e B foram incubadas com diferentes doses de calcário e submetidas à determinação do pH em H2O, do pH em CaCl2 0,01 mol L-1 e do teor de Al trocável extraído com KCl 1 mol L-1 e determinado por titulação com NaOH 0,02 mol L-1 e por espectrofotometria de absorção atômica. Em outro experimento, quatro espécies ou cultivares (arroz, cultivares Fernandes e IAC 1131; feijão, cultivar Rosinha, e milho, cultivar C511-A foram plantados em vasos contendo amostras dos horizontes A e B do solo em estudo; em 50% dos vasos, as amostras foram previamente tratadas com carbonatos de cálcio e de magnésio para elevar a saturação por bases a 80%. Após 60 dias, as raízes e a parte aérea foram secas, pesadas e submetidas à determinação do teor de Al. Em uma terceira etapa, foi determinado o teor de alumínio na solução do solo, empregando-se extratos da pasta de saturação de amostras incubadas com doses crescentes de calcário. Os teores de Al trocável obtidos por titulação do extrato com NaOH 0,02 mol L-1 mostraram-se coerentes com os determinados por espectrofotometria de absorção atômica. A influência da calagem sobre a produção de matéria seca e sobre a absorção de Al pelas plantas foi pequena, não havendo relação clara entre o desenvolvimento destas ou ocorrência de sintomas de toxidez e a presença de Al trocável nesse solo.

    Full Text Available Several electromagnetic signal types were observed prior to and immediately after 30 October 2007 (Local Time M5.4 earthquake at Alum Rock, Ca with an epicenter ~15 km NE of San Jose Ca. The area where this event occurred had been monitored since November 2005 by a QuakeFinder magnetometer site, unit 609, 2 km from the epicenter. This instrument is one of 53 stations of the QuakeFinder (QF California Magnetometer Network-CalMagNet. This station included an ultra low frequency (ULF 3-axis induction magnetometer, a simple air conductivity sensor to measure relative airborne ion concentrations, and a geophone to identify the arrival of the P-wave from an earthquake. Similar in frequency content to the increased ULF activity reported two weeks prior to the Loma Prieta M7.0 quake in 1989 (Fraser-Smith, 1990, 1991, the QF station detected activity in the 0.01–12 Hz bands, but it consisted of an increasing number of short duration (1 to 30 s duration pulsations. The pulsations peaked around 13 days prior to the event. The amplitudes of the pulses were strong, (3–20 nT, compared to the average ambient noise at the site, (10–250 pT, which included a component arising from the Bay Area Rapid Transit (BART operations. The QF station also detected different pulse shapes, e.g. negative or positive only polarity, with some pulses including a combination of positive and negative. Typical pulse counts over the previous year ranged from 0–15 per day, while the count rose to 176 (east-west channel on 17 October, 13 days prior to the quake. The air conductivity sensor saturated for over 14 h during the night and morning prior to the quake, which occurred at 20:29 LT. Anomalous IR signatures were also observed in the general area, within 50 km of the epicenter, during the 2 weeks prior to the quake. These three simultaneous EM phenomena were compared with data collected over a 1–2-year period at the site. The data was also compared against accounts of air

    Full Text Available ResumoO trabalho avalia as estratégias climáticas adotadas por multinacionais do setor de alumínio. A pesquisa adota uma abordagem qualitativa e toma por base entrevistas com gerentes de duas Multinacionais, uma delas instalada no Brasil e a outra no Canadá. As evidências empíricas demonstram que a multinacional do setor de alumínio que opera no Canadá enfatiza a redução de custos e a melhoria da eficiência operacional com projetos para reduzir emissões de gases do efeito estufa. A multinacional que opera no Brasil destaca, prioritariamente, o relacionamento com os stakeholders e a preocupação com a imagem corporativa para a adoção de uma estratégia de adaptação ou compensação das emissões de gases do efeito estufa. Em nenhum dos dois casos estudados, as pressões coercitivas, advindas de exigências regulatórias, figuram como fatores determinantes para a adoção de estratégias climáticas. O estudo conclui que, no caso da indústria de alumínio, características organizacionais são mais relevantes que as pressões institucionais na definição de estratégias climáticas.

    Full Text Available One of the main factors limiting agricultural production in tropical climate regions is mainly related to the presence of exchangeable aluminum (Al3+ in highly weathered acid soils. Four methods of Al3+ determination extracted with neutral 1 mol L¹ KCl solution were evaluated: three colorimetric methods (aluminon plus ascorbic acid, and eriochrome cyanine R by FIA and the usual titrimetric method with back-titration. Surface samples from 20 soils of different Brazilian regions, with active acidity (0.01 mol L¹ CaCl2 pH ranging from very high to medium (3.82 to 5.52, were used. The variance analysis revealed significant interaction among Al3+ determination methods and soil. Mean methods comparisons within each soil (Tukey, P 10 mmol c dm³. Among colorimetric methods, in operational terms, the eriochrome with FIA method presented analytical performance up to 50 samples per hour, easiness and sensibility for routine Al analysis in soil samples. However, due to the specificity, the titration/back-titration method should be used, despite the moroseness, when the Al3+ ions are the objective.Um dos principais fatores que afetam a produção agrícola em regiões de clima tropical, é a presença de alumínio trocável (Al3+ em solos ácidos altamente intemperizados.

    Full Text Available Background: The most important process in water treatment plant is coagulation and flocculation. Regular chemical coagulant which used in Iran are aluminum sulfate (Alum and ferric chloride. Chemical coagulants have hazardous effect on human health and their cost is high for developing country. The purpose of this study was to evaluate the comparison of chemical coagulants accompany with corn starch as a coagulant aid, for the turbidity removal from water. Methods: This study was accomplished in pilot-scale with synthetic turbid water using clay. In this research, initial turbidity of 250 and 500 NTU was experimented. Chemical coagulant dose during the experiment was 1, 2 and 5 ppm and natural coagulant dose was 0, 0.1, 0.3, 0.5 and 0.7 ppm. Results: The results showed that maximum removal efficiency of turbidity in initial turbidity of 250 NTU belonged to poly aluminum chloride with 5 ppm dosage and corn starch with 0.7 ppm dosage which removed and reduced the initial turbidity to 98.48% and 3.73 NTU, respectively. Moreover, in initial turbidity of 500 NTU the maximum removal efficiency was 98.52% which belonged to ferric chloride and corn starch (5 and 0.7 ppm respectively and reduced the initial turbidity to 7.4 NTU. Conclusions: The results of this study showed that using natural coagulant aid reduce the chemical coagulant consumption, and also does not have significant effect on pH range and reduce the health risks. While huge amount of required polyelectrolytes for water treatment plant imported to the country and the production of corn starch in our country is high, it is hope that the results of this project can be used in industrial scale.

    Full Text Available Foram estudados dez cultivares de trigo em soluções nutritivas contendo cinco diferentes níveis de alumínio tóxico. A tolerância foi medida pela capacidade de as raízes primárias continuarem a crescer em solução sem alumínio, após um período prévio de 48 horas em solução contendo uma concentração conhecida de alumínio. Os cultivares Siete Cerros e Tobari-66 foram sensíveis, respectivamente, a 1 e 3 ppm de alumínio. 'Alondra-S-46', 'Alondra-S-45' e 'IAC-17' foram sensíveis a 6 ppm; 'BH-1146', 'IAC-5', 'IAC-18', 'IAC-13' e 'Londrina' foram tolerantes a 10 ppm, porém 'BH-1146', 'IAC-18' e 'IAC-13' foram mais tolerantes que 'IAC-5' e 'Londrina'. Os cultivares BH-1146, IAC-17, Alondra-S-46, Tobari-66 e Siete Cerros foram cultivados em vasos contendo solo ácido mostrando a presença de alumínio. Metade do número de vasos recebeu uma aplicação de calcário. Os resultados desse experimento mostraram que o cultivar BH-1146 diferiu significativamente em produção de grãos por planta de 'Tobari-66', 'Alondra-S-46', 'IAC-17' e 'Siete Cerros'. Esse resultado confirmou a tolerância ao alumínio do cultivar BH-1146, observada quando se empregou solução nutritiva com a presença desse elemento.Ten wheat cultivars were studied to aluminum toxicity using five different levels of this element. The tolerance was measured taking into account the root growth in a aluminum-free complete nutrient solution after a previous Al treatment. With toxic amounts of Al, the primary roots did not grow at all and remained thickned at the tip as a typical Al injury. The wheat cultivars Siete Cerros and Tobari-66 were sensitive to 1 and 3 ppm of aluminum, respectively. The cultivars Alondra-S-46, Alondra-S-45 and IAC-17 were sensitive to 6 ppm. The cultivars BH-1146, IAC-5, IAC-18, IAC-13 and Londrina showed tolerance to 10 ppm but BH-1146, IAC-18 and IAC-13 were more tolerant than IAC-5 and Londrina.

    2014-06-01

    Full Text Available O presente artigo discute a inserção do Brasil no mercado mundial de alumínio a partir dos referenciais teóricos da ecologia política, da economia política do território e da saúde coletiva. A conjuntura contemporânea da economia mundial tem sido pautada pela desregulamentação e liberalização, característicos do ideário neoliberal propalado pelas nações centrais. A maior participação do Brasil nesse mercado tem sido realizada a partir do aumento da produção e exportação de commodities agrárias e metálicas, como o alumínio. Nesse sentido, a partir dos paradigmas da ecologia política, o texto propõe uma análise das consequências socioambientais, assim como sobre novas territorialidades que se produzem e reproduzem dentro de uma lógica econômica que privilegia as nações centrais. Do mesmo modo, procura-se compreender os dilemas da saúde coletiva sob uma perspectiva holística e integradora na qual se articula aos modelos de desenvolvimento econômico. Percebe-se que a produção e exportação de alumínio primário, apesar de apresentar um valor agregado maior, esconde um conjunto difuso de impactos que afetam o ambiente e a saúde coletiva.

    Bartlett, J.; Hardy, G.; Hepburn, I. D.

    2015-01-01

    The design and performance of a fast thermal response miniature (24 mm outer diameter by 30 mm long) Chromium Potassium Alum (CPA) salt pill is described. The need for a fast thermal response has been driven by the development of a continuously operating millikelvin cryocooler (mKCC) which uses 2 T superconducting magnets that can be ramped to full field in 30 s. The consequence of magnetising and demagnetising the CPA pill in such a short time is that thermal boundary resistance and eddy current heating have a significant impact on the performance of the pill, which was investigated in detail using modelling. The complete design of a prototype CPA pill is described in this paper, including the methods used to minimise thermal boundary resistance and eddy current heating as well as the manufacturing and assembly processes. The performance of the prototype CPA pill operated from a 3.6 K bath is presented, demonstrating that a complete CPA cycle (magnetising, cooling to bath and demagnetising) can be accomplished in under 2.5 min, with magnetisation and demagnetisation taking just 30 s each. The cold finger base temperature of the prototype varies with demagnetisation speed as a consequence of eddy current heating; for a 30 s demagnetisation, a base temperature of 161 mK is obtained, whilst for a 5 min demagnetisation, a base temperature of 149 mK was measured (both from a 3.6 K and 2 T starting position). The measured hold times of the CPA pill at 200 mK, 300 mK, and 1 K are given, proving that the hold time far exceeds the recycle time and demonstrating the potential for continuous operation when two ADRs are used in a tandem configuration. The ease and speed at which the CPA pill temperature can be changed and controlled when stepping between operating temperatures in the range of 200 mK to 4 K using a servo control program is also shown, once again highlighting the excellent thermal response of the pill. All of the test results are in good agreement with the

    Full Text Available In the new planning of Hannover, a new elevated roadway has been provided, to connect the Königsworther place with the Westtangente motor road. This elevated road is built on a prestressed concrete palisade which is 360 m long and forms 17 spans, whose mean length is 22 m. The road runs on a curve, and there are two dilation joints, separating the structure into three sections. The deck is prestressed, and rests on portal frames, with inclined columns, whose top cross members, also prestressed, cantilever 1.24 ms on each side of the columns. The longitudinal prestressing cables have been given a load of 116 tons per cable, and the transversal ones, spaced every 0.75 m, carry a load of 57 tons per cable. This project was finished very rapidly, thanks to the magnificent auxiliary facilities. The concrete was transported from the mixing plant to the site, about 200 m away, by pneumatic pumps. A special feature of this project is that the lower ends of the columns rest on the foundations by means of sets of roller bearings, which are carefully greased.En la nueva ordenación urbana de la ciudad de Hannover (Alemania, se ha incluido un acceso elevado, especie de puente, que unirá la plaza de Königsworther con la autopista Westtangente. Este acceso es de hormigón pretensado y tiene una longitud total de 360 m, subdividida en 17 tramos de unos 22 m de luz media. Como el trazado tiene un eje en curva, se han previsto dos juntas que dividen el acceso en tres trozos. El tablero es de hormigón pretensado y se apoya sobre una serie de pórticos, con montantes inclinados, cuyos cabezales, también pretensados, tienen 1,24 m de canto y se prolongan en voladizo por ambos lados. Los cables del pretensado longitudinal se han tesado a razón de 116 t cada uno y los del pretensado transversal, especiados a 0,75 m, a 57 t por cable. Esta obra se terminó con gran celeridad, gracias a las magníficas instalaciones auxiliares dispuestas. El hormigón se transportó de la hormigonera al lugar de colocación, distante unos 210 m, por medio de dos bombas neumáticas. Presenta la particularidad de que la parte inferior de los montantes se unen a sus apoyos por medio de cajas de rodillos convenientemente engrasados.

    Llewellyn, B D

    2009-08-01

    The hematoxylin and eosin stain is the most common method used in anatomic pathology, yet it is a method about which technologists ask numerous questions. Hematoxylin is a natural dye obtained from a tree originally found in Central America, and is easily converted into the dye hematein. This dye forms coordination compounds with mordant metals, such as aluminum, and the resulting lake attaches to cell nuclei. Regressive formulations contain a higher concentration of dye than progressive formulations and may also contain a lower concentration of mordant. The presence of an acid increases the life of the solution and in progressive solutions may also affect selectivity of staining. An appendix lists more than 60 hemalum formulations and the ratio of dye to mordant for each.

    Full Text Available OBJECTIVE: To evaluate fluoride and aluminum concentration in herbal, black, ready-to-drink, and imported teas available in Brazil considering the risks fluoride and aluminum pose to oral and general health, respectively. METHODS: One-hundred and seventy-seven samples of herbal and black tea, 11 types of imported tea and 21 samples of ready-to-drink tea were divided into four groups: I-herbal tea; II-Brazilian black tea (Camellia sinensis; III-imported tea (Camellia sinensis; IV-ready-to-drink tea-based beverages. Fluoride and aluminum were analyzed using ion-selective electrode and atomic absorption, respectively. RESULTS: Fluoride and aluminum levels in herbal teas were very low, but high amounts were found in black and ready-to-drink teas. Aluminum found in all samples analyzed can be considered safe to general health. However, considering 0.07 mg F/kg/day as the upper limit of fluoride intake with regard to undesirable dental fluorosis, some teas exceed the daily intake limit for children. CONCLUSIONS: Brazilian and imported teas made from Camellia sinensis as well as some tea-based beverages are sources of significant amounts of fluoride, and their intake may increase the risk of developing dental fluorosis.OBJETIVO: Avaliar as concentrações de flúor e alumínio em chás brasileiros de ervas, preto e bebidas a base de chá, como em chás preto importados considerando seus riscos para, respectivamente, a saúde oral e geral. MÉTODOS: Foram analisadas 177 amostras de chá de ervas e chá preto, 11 tipos de chá preto importados e 21 amostras de bebidas à base de chá. Flúor e alumínio foram determinados após infusão dos chás de ervas e pretos. As determinações de flúor e alumínio foram feitas por eletrodo específico e absorção atômica, respectivamente.

    Full Text Available Aluminum toxicity is one of the major limiting factor regarding plant development in acid soils. The use of liming for correcting soil pH is not viable for some of acid soil areas (technique or economic reasons, making the development of Al tolerant genotypes the best alternative. Thus, the tolerance mechanisms as well as the genetic basis of Al tolerance has deserved special attention in the scientific community. In the last years, a significant progress has been achieved towards these goals, as well as in developing cultivars adapted to acid soils. The Al tolerance mechanisms are divided basically in two classes: the exclusion mechanisms that act after absorption or blocking its entry in the root system and those involved in detoxification, complexing the Al in specific organelles, mainly in the vacuoles. In many species, physiological mechanisms have been reported as responsible for the activation of organic acids (mainly citrate and malate that act as Al quelating agents, however many process are not yet understood and cleared. Currently, the basis for the internal detoxification is becoming clear through organic acid complexes and there sequestering by the vacuoles. Other potential mechanisms are the target for discussions.A toxicidade do alumínio é um dos principais fatores limitantes do desenvolvimento das plantas em solos ácidos. Pelo fato da utilização de corretivos da acidez do solo não ser a estratégia mais viável em muitas situações com solos ácidos (por razões técnicas e econômicas, o desenvolvimento de genótipos tolerantes ao Al tem sido o caminho mais focado, assim a investigação dos mecanismos de tolerância bem como as bases genéticas da tolerância ao Al têm merecido atenção especial pela pesquisa científica.

    O alumínio trivalente (Al+3) é altamente tóxico e é o principal fator de estresse para plantas sensíveis em solos ácidos. Contudo, muitas espécies são bem adaptadas a condições de solos ácidos e a elevadas concentrações de Al. Os mecanismos de adaptação das plantas podem ser divididos em: a) resistência: exclusão do Al a partir de células do sistema radicular e, b) tolerância: entrada e sequestro do Al para os órgãos vegetais.

    Carlos Eduardo de Oliveira Camargo

    1983-01-01

    Full Text Available Em condições controladas de crescimento, foram estudados 22 cultivares de arroz, em soluções nutritivas com temperaturas de 25 ± 1°C e 30 ± 1°C, com cinco diferentes níveis de alumínio, em recipientes de 8,3 litros com 330 plântulas por recipiente. A tolerância foi medida pela capacidade de as raízes primárias continuar a crescer, em solução sem alumínio, após um período de 72 horas em solução contendo uma concentração conhecida de alumínio. Nas soluções nutritivas com temperatura de 25 ± 1°C, os cultivares IAC-899 e IR-841 foram sensíveis a 10mg/litro de Al3+; IR-43, IR-45 e IR-8, foram sensíveis a 20mg/litro de Al3+; CICA-4 e IR-42, a 40mg/litro de Al3+, e IAC-435, IAC-164, Pérola, Batatais, Pratão Precoce, Blue Bonnet, IAC-120, IAC-47, IAC-1246, IAC-25, IAC-165, Pratão, Dourado Precoce e CICA-8 foram tolerantes a 40mg/litro de Al3+. Quando foram utilizadas soluções nutritivas com temperatura de 30 ± 1°C, todos os cultivares de arroz estudados apresentaram melhor desenvolvimento radicular do que a 25 ± 1°C e se mostraram tolerantes a 5, 10 e 20mg/litro de Al3+. Com a concentração de 40mg/litro de Al3+, os cultivares Dourado Precoce, CICA-4, IR-42, IR-43, IR-45, IR-8, IAC-899, IR-665-4-5-5 e IR-841 foram sensíveis; IAC-47, Blue Bonnet, IAC-1246, IAC-164, Pratão, Pratão Precoce, CICA-8, IAC-435, IAC-120, IAC-25, IAC-165, Pérola e Batatais, tolerantes. A presença do alumínio nas soluções nutritivas foi prejudicial a todos os cultivares tolerantes e sensíveis. Os dados obtidos permitiram classificar os cultivares estudados nas seguintes classes de tolerância ao alumínio: tolerantes: IAC-435, IAC-120, IAC-47, IAC-1246, IAC-25, IAC-165, IAC-164, Pérola, Batatais, Pratão Precoce, Blue Bonnet; moderadamente tolerantes: Pratão, Dourado Precoce e CICA-8, e sensíveis: CICA-4, IR-42, IR-43, IR-45, IR-8, IAC-899, IR-665-4-5-5 e IR-841.Twenty two rice cultivars were studied in nutrient solution in

    1998-03-01

    Full Text Available O gesso, nos últimos anos, vem sendo considerado como um insumo capaz de melhorar o ambiente radicular de subsolos ácidos. Contudo, ainda pairam dúvidas sobre a vantagem de usá-lo em solos que, embora ácidos, tenham sido submetidos a calagens e adubações anteriores. Também há pouca informação sobre o uso de gesso em presença de aplicações elevadas de calcário ou em plantas cultivadas tolerantes à acidez. No presente trabalho, é relatado experimento com calcário e gesso, realizado, de 1987 a 1992, na Estação Experimental de Tatuí (SP, em Latossolo Vermelho-Escuro álico textura argilosa, com o objetivo de avaliar o efeito de calcário e de gesso nas produções de cultivares de milho tolerante ou susceptível a alumínio, bem como o efeito dos corretivos na acidez do solo. O experimento foi instalado em parcelas subsubdivididas, com quatro repetições, em blocos ao acaso. Nas parcelas principais, foram aplicadas 0, 6 ou 12 t ha-1 de calcário dolomítico e, nas subparcelas, 0, 4 e 8 t ha-1 de fosfogesso; nas subsubparcelas, foram plantados dois cultivares, um sensível e outro tolerante a alumínio. Para as quatro colheitas obtidas (os dados de 1990 foram considerados perdidos, percebeu-se efeito significativo para a calagem nos dois tipos de cultivares. O gesso apresentou efeito significativo nas produções apenas para o cultivar sensível ao alumínio e, nesse caso, o efeito foi aditivo ao de calcário, proporcionando, em média, cerca da metade do aumento de produção devida à calagem. A calagem influenciou, consideravelmente, a reação da camada arável do solo, aumentando o pH, os teores de Ca2+ e Mg2+ e reduzindo a acidez potencial, mas pouco influiu nas camadas mais profundas, o que, provavelmente, se deveu ao fato de o solo ter recebido aplicações anteriores de calcário e de adubos com sulfato. O gesso influiu nos teores de Ca2+ e SO4(2- em profundidade, embora de forma pouco pronunciada em relação

    Full Text Available Concretos refratários são usualmente materiais de baixas porosidade e permeabilidade. Devido a isso, a retirada da água adicionada às formulações durante a mistura deve ser feita de modo cuidadoso para minimizar os riscos de explosão e danos mecânicos envolvidos. Por outro lado, a crescente utilização de concretos refratários em revestimentos de calcinadores para a indústria de alumínio e o período de lucro cessante durante essa etapa do processamento desses materiais indica que programas de aquecimento otimizados possam se tornar um importante diferencial competitivo para as empresas. Na tentativa de conciliar esses aspectos, aditivos para facilitar o processo de secagem e torná-lo mais seguro foram desenvolvidos. Entre os principais, destacam-se o pó de alumínio, as fibras poliméricas convencionais e as de alto desempenho. Neste trabalho, são apresentados seus mecanismos de atuação e comparações em relação às condições que otimizam seu desempenho.Refractory castables are low porosity and permeability materials. Due to this, the first heat up must be carried out in a careful way in order to avoid the risks of explosive spalling and mechanical damages during the water withdrawn. On the other hand, the growing use of refractory castables in the aluminum industry, as calciners lining, and the lack of production during their placement indicate that optimized heating schedules may become an important competitive advantage to the companies. In order to join these two aspects, additives to easy the drying process and to make it safer were developed. These drying additives behave, generally, increasing the castable permeability in a more controlled way. The most important ones are the aluminum powder and the polymeric fibers. In the present work, their mechanisms and the most suitable processing condition for their use are presented.

    Full Text Available Os resultados bem-sucedidos apresentados na literatura acerca da soldagem por atrito com pino não consumível das juntas alumínio-aço, desconsideram o aspecto e formação de defeitos na junta como pontos de referência para sua avaliação. Igualmente aumenta a controvérsia acerca da presença de compostos intermetálicos do tipo Fe xAl y, somado à falta de informação sobre sua origem. O objetivo deste trabalho é determinar parâmetros adequados para a obtenção de juntas alumínio-aço livres de defeitos e sua relação com a formação de fases deletérias durante a soldagem por atrito com pino. Foram obtidas juntas soldadas consolidadas e foi determinada a microestrutura resultante destas juntas soldadas da liga de alumínio 6063-T5 e aço AISI SAE 1020. Utilizou-se uma ferramenta de carbeto de tungstênio (WC-14Co a velocidades de rotação e de avanço de 300 rpm e 150 mm.min-1, respectivamente. Foram empregados deslocamentos da ferramenta de +0,5; +1,0 e +1,5 mm. Os resultados realçam a importância do aporte energético na obtenção de juntas alumínio-aço com aspecto superficial e penetração adequados. A análise microestrutural revela a formação de sete regiões na junta soldada, destacando a zona termo-mecanicamente afetada no lado do aço, uma banda de grãos ultra finos de ferrita e a ausência de compostos intermetálicos na interface alumínio-aço.

    Full Text Available A germinação das sementes pode ser fortemente influenciada pelas condições ambientais, afetando o estabelecimento de comunidades florísticas. As plantas daninhas, apesar das características de rusticidade e capacidade de suas sementes germinarem em condições de estresse ambiental, podem sofrer o efeito direto da presença de elementos tóxicos no substrato. O alumínio, presente em solos com pH baixo, pode interferir negativamente no processo germinativo de sementes de espécies cultivadas e também de plantas daninhas. No presente trabalho, objetivou-se estudar o efeito tóxico da presença de alumínio no substrato durante a germinação de sementes de Conyza. A germinação foi reduzida pela presença de alumínio no substrato, havendo decréscimos significativos a partir de 1,5cmol c dm-3 para as sementes de ambas as espécies, enquanto a velocidade de germinação foi prejudicada a partir da menor concentração (0,5cmol c dm-3 de alumínio testada. Esses resultados demonstram que as sementes de ambas as espécies são sensíveis à presença de alumínio no substrato de germinação.Seed germination can be greatly influenced by environmental conditions, which affects the establishment of floristic communities. The weeds, although they had features as hardiness and its ability to germinate seeds under environmental stress conditions, may experience the direct effect of the presence of toxic elements in the substrate. Aluminum, present in soils with low pH can negatively impact the germination of seeds of crop species and weeds. This research aimed to study the toxic effect of aluminum presence in the substrate during seed germination of Conyza. Germination was reduced by the presence of aluminum in the substrate, with significant decreases from 1.5cmol c dm-3 for the seeds of both species. The germination rate was affected from the lower concentration of aluminum tested (0.5cmol c dm-3. These results demonstrate that the seeds of

    Full Text Available Plants present different degrees of adaptation to aluminium (Al concentrations in the soil, and the understanding of this characteristic can lead to a viable option for the utilization of acid soils. The objective of this experiment was to evaluate the effects of five Al concentrations (0, 50, 100, 200, and 400 mumol L-1 on the growth of 'Rangpur' lime (Citrus limonia Osbeck and 'Volkamer' lemon (Citrus volkameriana Hort. ex Tan., and tangerine rootstocks 'Cleópatra' (Citrus reshni Hort. ex Tan and 'Sunki' (Citrus sunki Hort. ex Tan., in hydroponic culture. The treatments were arranged in a randomized block design, with four replications. For all rootstocks, the relative growth rate in terms of plant total fresh matter increased under low and, decreased under large Al concentrations. Growth of the shoot, leaf area ratio and leaf weight ratio decreased for all rootstocks in the presence of Al. The 'Rangpur' lime had a decrease of the root system growth, starting from 23 mumol L-1 of Al. For the remaining rootstocks, this growth reached maximum values at 91 to 117 mumol L-1 of Al, respectively. Considering all the evaluated characteristics of plant growth, the 'Rangpur' lime was the most susceptible to Al.As plantas apresentam diferentes graus de tolerância aos efeitos tóxicos do alumínio (Al, e a exploração dessa característica pode ser uma opção viável para a utilização dos solos ácidos. Este experimento teve como objetivo avaliar os efeitos de cinco concentrações de alumínio (0, 50, 100, 200 e 400 mimol L-1 de Al sobre o crescimento dos porta-enxertos limoeiros 'Cravo' (Citrus limonia Osbeck e 'Volkameriano' (Citrus volkameriana Hort. ex Tan., e tangerineiras 'Cleópatra' (Citrus reshni Hort. ex Tan e 'Sunki' (Citrus sunki Hort. ex Tan. em cultivo hidropônico.

    Full Text Available Neste trabalho, suco de laranja natural foi pasteurizado em um trocador de calor a placas empregando três diferentes temperaturas de pasteurização: 82,5ºC; 85,0ºC e 87,0ºC e tempos de retenção variando de 11 a 59s, para se obter um produto minimamente processado. Um estudo comparativo foi realizado no suco de laranja armazenado em latas de alumínio em relação ao mesmo produto armazenado em garrafas PEAD, sob refrigeração, por um período de 21 dias. Análises de graus Brix, pH, acidez, sólidos insolúveis e totais e análises microbiológicas foram realizadas em amostras logo após o processamento e durante o período de armazenamento. As propriedades físico-químicas do suco de laranja pasteurizado apresentaram diferenças devido as diferenças detectadas na matéria-prima ao longo do período do estudo. O parâmetro de pasteurização mais apropriado para o suco de laranja natural foi 87,0ºC e com tempo de retenção variando de acordo com o pH do suco. Para pH 4,0 o tempo de retenção requerido foi maior. De acordo com os resultados, uma vida-de-prateleira de 15 dias foi determinada para o suco processado nas condições acima.

    Full Text Available O sisal é um recurso estratégico para a região Nordeste e, particularmente, para o estado do Rio Grande do Norte, por ser uma cultura renovável e adaptada às condições do semi-árido. Em virtude das condições adversas de clima e solo, o sisal é, em algumas regiões, o único produto agrícola rentável passível de plantio. Agregar valor aos produtos manufaturados a partir do sisal contribui não só para o desenvolvimento científico e tecnológico da região, como também para a geração de renda para a população dos municípios potiguares produtores de sisal. Da planta extraem-se fibras ligninocelulósicas utilizadas na produção artesanal de cordas e industrial de mantas e tapetes. Uma outra alternativa é o aproveitamento da estrutura da fibra para a produção de fibras de alumina (Al2O3 pela biomodelagem. Este processo consiste na reprodução da estruturas natural do material de partida. O objetivo deste trabalho foi estudar as condições de infiltração da fibra de sisal com sal de alumínio para posterior conversão da estrutura em fibras de alumina. Inicialmente, as fibras de sisal foram pré-tratadas com hidróxido de sódio, infiltradas com uma solução saturada de sal de alumínio (Al2Cl6 e sinterizadas entre 1400 °C e 1650 °C. A caracterização das fibras de alumina foi feita por difração de raios X e microscopia eletrônica de varredura. Os resultados mostraram a conversão completa apenas da superfície da fibra de sisal em alfa-Al2O3, resultando em baixa resistência ao manuseio. Novos métodos de infiltração são propostos com o objetivo de reproduzir-se a estrutura interna da fibra de sisal, resultando em fibras materiais com melhor resistência mecânica.Sisal is a renewable agricultural resource adapted to the hostile climatic and soil conditions particularly encountered in the semi-arid areas of the state of Rio Grande do Norte, located in Northeastern Brazil. Consequently, sisal has played a

    Full Text Available O termo erodibilidade do solo (fator K na Equação Universal de Perda de Solo - EUPS expressa a suscetibilidade natural do solo à erosão hídrica. O fator K representa a taxa de perda de solo por unidade de erosividade da chuva (fator R na EUPS. O conhecimento do fator K, juntamente com os demais fatores do modelo EUPS, é importante no planejamento conservacionista, pois, por meio desse modelo, estimam-se as perdas médias anuais de solo esperadas para determinadas condições. Dados de perda de solo, obtidos em campo em solo sem cultivo e com preparo convencional, sob condições de chuva simulada, no período de novembro de 2001 a março de 2004, no sul do Planalto Catarinense, foram utilizados para calcular o fator K de um Nitossolo Háplico alumínico típico, com declividade média de 0,15 m m-1. O fator K foi calculado pela razão entre as perdas de solo e a erosividade das chuvas e, ainda, estimado por análise de regressão linear simples entre estas duas variáveis. Foram utilizados valores de erosividade das chuvas (EI30 de 11 testes de chuva simulada e suas respectivas perdas de solo, obtidas em parcelas de 3,5 x 11,0 m, desprovidas de vegetação e de crosta superficial, após terem sido mantidas sem cultivo e sob preparo de solo contínuo por dois anos. O preparo do solo, executado no sentido do declive, duas vezes ao ano, consistiu de uma aração e duas gradagens. A crosta superficial e as plantas espontâneas eram mecanicamente eliminadas por meio de escarificação e de capina manual com enxada.

    Full Text Available The Oxisols of the Cerrado region have a simple mineralogy, and are composed mainly of kaolinite and iron and aluminium oxides. The aim of this work was to perform a sequential extraction of iron and aluminium and to relate them to texture, mineralogy and organic carbon in Oxisols of the Cerrado region. The soil samples, 35 in total, were taken from the 0–20 cm layer in Oxisols under pasture located in the Brazilian Cerrado Region. The levels of iron and aluminum extracted by full attack, dithionite-citrate-bicarbonate, ammonium oxalate and sodium pyrophosphate were analyzed according to the textural classes using the Kruskal-Wallis nonparametric test. Then these data were related to the mineralogy and organic carbon through a principal component analysis. Whatever the textures, iron oxides of high degree of crystallinity were the main form of iron and are positively correlated with the iron total content. The aluminum oxides have a high affinity to organic carbon than iron oxides. The levels of iron and aluminum extracted by sodium pyrophosphate were closely related to soil pH.Os Latossolos da região do Cerrado apresentam mineralogia da fração argila relativamente simples, sendo constituídos principalmente por caulinita e óxidos de ferro e de alumínio. O objetivo deste trabalho foi realizar extrações sequênciais de ferro e de alumínio e relacioná-los à mineralogia, textura e teores de carbono orgânico em Latossolos da região do Cerrado. Coletaram-se 35 amostras na camada de 0-20 cm de Latossolos sob pastagem da Região do Cerrado. Os teores de ferro e de alumínio extraídos pelo ataque total, ditionito-citrato-bicarbonato de sódio, oxalato ácido de amônia e pirofosfato de sódio foram analisados de acordo com a classe textural através do teste não paramétrico de Kruskal-Wallis. Em seguida estes dados foram relacionados com a mineralogia e o carbono orgânico por meio de uma análise de componentes principais

    Full Text Available Dentre todas as fruteiras de clima temperado, a macieira é a que mais atenção tem recebido no sentido de se obterem porta-enxertos com características de boa adaptação, resistência ou sanidade. O desenvolvimento de um método eficiente para caracterizar genótipos com tolerância ao alumínio é o primeiro passo para a realização de estudos de mecanismos genéticos envolvidos na herança desse caráter. Assim, o presente trabalho teve por objetivo avaliar a tolerância ao alumínio dos porta-enxertos de macieira M.9 e Marubakaido em cinco concentrações (0; 50;150; 250 e 350 µM L-1 em solução nutritiva. As estacas de Marubakaido, na concentração intermediária de alumínio apresentaram menor crescimento radicular e aéreo. O M.9 mostrou menor crescimento radicular nas concentrações de 250 e 350 mM de alumínio. As características de crescimento avaliadas permitiram discriminar o porta-enxerto Marubakaido como mais tolerante que o M.9, e a concentração de 350 µM L-1 é a mais eficiente para a discriminação da tolerância ao alumínio aos 15 dias de cultivo em solução nutritiva.Among all of the temperate fruit trees, the apple tree is the one that has attracted more attention when it comes to obtaining rootstocks with characteristics of good adaptation, resistance or sanity. The development of an efficient method to characterize genotypes with tolerance to the aluminum is the first step for the accomplishment of genetic mechanisms studies involved in the inheritance of this character. Thus, the present work aimed to evaluate the tolerance to aluminum of the apple tree rootstocks M.9 and Marubakaido in five concentrations (0, 50, 150, 250 and 350 µM L-1 in nutritious solution. The cuttings of Marubakaido, in the intermediate concentration of aluminum presented smaller root and aerial growth. M.9 showed smaller root growth in the concentrations of 250 and 350 µM of aluminum. The evaluated growth characteristics permitted

    Full Text Available Foi estudado o comportamento diferencial de 12 genótipos de trigo comum (Triticum aestivum L., um genótipo de trigo duro (Triticum durum L., e um de triticale (Triticosecale sp em soluções nutritivas de tratamento contendo duas concentrações salinas (1/5 e 1/10 da completa e seis concentrações de alumínio ( 0, 2, 4, 6, 8 e 10 mg L-1, à temperatura de 25 ± 1ºC e pH 4,0. Foram utilizadas dez plântulas por parcela e quatro repetições. A tolerância foi medida pela capacidade de as raízes primárias continuarem a crescer em solução sem alumínio, após permanecer 48 horas em solução nutritiva completa, contendo uma concentração conhecida de alumínio combinada com cada uma das concentrações salinas. Os genótipos de trigo comum IAC-289, IAC-350 e IAC-370 e a cultivar controle Anahuac, e os genótipos de trigo duro IAC-1003 e de triticale IAC-5 foram os mais sensíveis a níveis crescentes de Al3+nas soluções nutritivas de tratamento e, portanto, somente seriam indicados para cultivo em solos corrigidos. Os genótipos de trigo comum IAC-24 e IAC-378 e a cultivar controle BH-1146 destacaram-se pela tolerância à toxicidade de Al3+, com potencial para uso em solos ácidos e como fontes genéticas de tolerância nos futuros cruzamentos. Os sintomas de toxicidade de alumínio foram maiores com a elevação da concentração de alumínio e da diminuição das concentrações de sais da solução nutritiva para todos os genótipos estudados.Twelve bread wheat (Triticum aestivum L., one durum wheat (Triticum durum L. and one triticale (Triticosecale sp genotypes were studied in nutrient solutions with a high salt concentration in experiment 1 and a weak salt concentration in experiment 2, for aluminum tolerance at six levels: 0, 2, 4, 6, 8 and 10 mg L-1, under temperature 25 ± 1ºC and pH 4,0.

    ífica demuestra a lo largo de los últimos años que el Al es uno de los determinantes para el desenvolvimiento de la EA.O objetivo do estudo foi condensar a evidência científica existente entre a exposição ao alumínio (Al e risco para o desenvolvimento da doença de Alzheimer (DA, avaliando os efeitos para saúde da população, a longo prazo. Realizou-se revisão sistemática de literatura produzida entre 1990 e 2005, conduzida em duas bases de dados, MEDLINE e LILACS, utilizando os unitermos: "Aluminium exposure and Alzheimer Disease" e "Aluminium and risk for Alzheimer Disease". Foram selecionados 34 trabalhos para a pesquisa, desses, 68% estabeleceram relação entre o Al e a DA, 23,5% não apresentaram dados conclusivos e 8,5% não estabeleceram nenhuma relação entre o Al e DA. A partir dos resultados obtidos, verifica-se que o Al intervém em diversos processos neurofisiológicos responsáveis pela degeneração característica da DA. Apesar da polêmica existente, a evidência científica demonstra, ao longo dos últimos anos, que o Al se associa com o desenvolvimento da DA.

    Full Text Available Nos setores industriais relacionados à aeronáutica e automobilística, tem-se buscado o desenvolvimento e a aplicação de ligas metálicas leves com o intuito da redução de massa dos produtos e consequente redução do consumo de combustível. Por suas dimensões e requisitos estruturais, componentes e seções de aviões e automóveis são produzidos através da união por processos de soldagem por fusão. Entretanto, processos de soldagem no estado sólido são preferíveis por evitar defeitos decorrentes da fusão, e têm sido objeto de estudo nas últimas duas décadas. Este trabalho teve por objetivo a caracterização de uma solda por FSW - Friction Stir Welding em junta de topo, da Liga de Alumínio 2198-T851 com espessuras diferentes (configuração "Tailored Blanks". A metodologia utilizada na caracterização envolveu a determinação das propriedades mecânicas das juntas soldadas, compreendendo ensaios de tração e determinação de perfil de microdureza na seção transversal; e buscou-se compreender a relação entre as alterações microestruturais promovidas pelo processo de soldagem e as propriedades resultantes. Concluiu-se que, devido aos fenômenos metalúrgicos decorrentes do processo de soldagem utilizado, alterações microestruturais tais como refino de grão, encruamento e dissolução/formação de fases precipitadas permitiram a obtenção de uma solda cujas propriedades mecânicas de tração (salvo alongamento igualaram-se a ou excederam aquelas do metal base, evidenciando a viabilidade de utilização dos parâmetros de soldagem por FSW utilizados neste trabalho.In both aeronautic and automobile related industries, development and application of light-weighted metallic alloys have been pursued with the intention of reducing product weight and consequent fuel consumption. Due to their dimension and structural requirements, components and sections from airplanes and automobiles are produced through fusion

Foi utilizado um aparelho de raios X odontológico convencional, operando com 60 kVp e 70 kVp, e filmes radiográficos dos grupos D e E de sensibilidade. Foram realizadas radiografias de um "phantom" e de uma escala de densidade de alumínio. Os resultados mostraram que o uso dos filtros de liga Al-Zn resultou em um não-endurecimento dos feixes. A taxa de kerma no ar diminuiu em até 18,53%, sem alteração no contraste das radiografias e a qualidade das imagens teve uma boa aceitação pelos examinadores. A análise dos resultados nos levou a concluir que o filtro de liga Al-Zn 2%, com 1,99 mm de espessura, tensão de 60 kVp, quando usado com filme D, foi o que obteve melhor desempenho, reduzindo a taxa de kerma no ar sem variar o índice de contraste das radiografias, mantendo a qualidade da imagem aceitável para diagnóstico, sem contudo aumentar o tempo de exposição.The aim of this study was to evaluate the effects of alternative filtration with the aluminum-zinc alloy in dental X-ray devices, regarding the energy spectrum, dose, contrast and image quality. This study was carried out comparing the conventional aluminum filter with aluminum-zinc alloy filters of various thicknesses and with different percentages of zinc in the alloy (2, 3, 4 and 5%. A conventional X-ray device operating with 60 and 70 kVp as well as D- and E-speed films were utilized in order to obtain images of a phantom and an aluminum step wedge. The utilization

    in plant fertilization are discussed.O triticale constitui uma cultura tolerante a condições climáticas e edáficas extremas, estando bem adaptado a solos ácidos, com níveis tóxicos de Al. A satisfação das necessidades cerealíferas crescentes da população mundial é o desafio fundamental da agricultura sustentável, evitando a poluição antropogénica, frequentemente por compostos azotados contaminantes de aquíferos e da atmosfera. Foi estudado o enriquecimento amoniacal na adubação azotada em triticale, na presença de alumínio tóxico. As plantas com três dias do genótipo tolerante ao Al TTE 9203 foram sujeitas à presença de 0 ou 370 mM Al e receberam as quatro proporções de NO3-/ NH4+ seguintes 15:1, 8:1, 3:1 e 1:1, tendo sido fixada a concentração total de 3,2 mM N nas diferentes modalidades em solução nutritiva. Relativamente aos correspondentes controlos, os tratamentos com 370 mM Al induziram reduções importantes no crescimento, que variaram significativamente entre 75,3% e 47,3% do comprimento radicular, 80% a 60% da biomassa radicular e 89% a 71% da biomassa aérea, segundo a proporção de NO3-/ NH4+ presente na solução nutritiva. Efectivamente, o Al tóxico reduziu muito significativamente a absorção de nitrato pelas plantas. O efeito negativo do Al nas jovens plantas foi mais evidente na modalidade com a proporção 15:1 NO3-/ NH4+, tendo a presença de Al provocado as reduções de 52,7 % do alongamento da radícula mais longa e de 40,6 % da biomassa fresca de raiz produzida em quatro dias de tratamento. Pelo contrário, na modalidade com a proporção 8:1 NO3-/ NH4+, as raízes das plantas sofreram as reduções mínimas daqueles parâmetros relativamente ao correspondente controlo (24,7 % e 20,3 %, respectivamente. No seu conjunto, os resultados obtidos indicaram que o NH4+ pode aliviar a toxicidade do Al em triticale, na fase vegetativa precoce que constitui a mais susceptível à toxicidade daquele metal.

    Full Text Available A poluição do solo com elementos-traço tem sido motivo de preocupação nos últimos anos, o que justifica melhor conhecimento da disponibilidade desses elementos no ambiente, visando amenizar seus efeitos em áreas contaminadas. Este trabalho teve como objetivo avaliar o desempenho de um subproduto da indústria de alumínio como amenizante de solos contaminados com Cd e Pb. Foram utilizados um Neossolo Quartzarênico (930 g kg-1 de areia, 20 g kg-1 de silte e 50 g kg-1 de argila e um Latossolo Vermelho (360 g kg-1 de areia, 100 g kg-1 de silte e 540 g kg-1 de argila contendo 15 % de solo contaminado com Cd e Pb. Foram feitas cinco repetições testando-se o efeito da aplicação do subproduto in natura a 0; 0,25; 0,50; 1,00; e 2,00 %. Para comparação, utilizaram-se calcário, silicato e turfa a 0,25; 0,50; e 2,00 %, respectivamente, e cada um dos solos sem contaminação. Cultivou-se B. decumbens, fazendo coletas de lixiviado e determinando o pH e a CE. As concentrações de Cd e Pb foram avaliadas no lixiviado não-filtrado e filtrado (0,45 µm. Avaliaram-se a produção de matéria seca de raízes (MSR e da parte aérea (MSPA e as quantidades de Cd e Pb em ambas após digestão nitroperclórica. Os amenizantes contribuíram para aumentar o pH dos lixiviados do Neossolo Quartzarênico e do Latossolo Vermelho, tendo este último apresentado menores valores de condutividade eletrolítica quando comparado ao primeiro. Os teores de Cd nos lixiviados filtrados (fração solúvel foram os mesmos dos lixiviados não-filtrados, enquanto os de Pb apresentaram diferenças. As produções de MSR e MSPA aumentaram com o aumento das taxas de aplicação do subproduto, e a quantidade de Cd na MSPA da B. decumbens foi maior que a de Pb.Soil pollution with trace elements has been of great concern in the last years due to the increase in contaminated areas, which calls for a better understanding of trace element availability and environmental remediation

    Full Text Available A toxicidade do alumínio em solos é considerada uma das maiores limitações para a produção das culturas. No entanto, algumas plantas são capazes de tolerar altas concentrações de alumínio por sua complexação com ácidos orgânicos exsudados pelas raízes. No intuito de estudar os efeitos concomitantes de faixas pH e de alumínio no desenvolvimento radicular de plântulas de soja, desenvolveu-se um trabalho na solução de um Argissolo Vermelho distrófico típico de campo natural. Cultivou-se, em câmara de crescimento, plântulas pré-germinadas de soja durante três dias dentro de tubos de ensaio aerados contendo 40ml da solução do solo (4,2µmol de Al L-1, submetidos a quatro concentrações de alumínio (0,0; 0,3; 0,6 e 1,2µmol L-1 e três níveis de pH (4,0; 5,0 e 6,0. O crescimento radicular e da parte aérea da soja foi menor em condições mais ácidas (pH 4,0. Em condições de acidez intermediária (pH H2O 5,0, o crescimento radicular foi menos afetado pelas espécies rizotóxicas de alumínio, mesmo quando submetidas a elevadas concentrações de alumínio na solução do solo.Aluminum toxicity in soils is considered one of the major limitations to crop production. However, some plants are able to tolerate high aluminum concentrations due to its complexation with root organic acids exudates. The simultaneous effect of pH ranges and aluminum concentration in soil solution on soybean seedlings root development was studied in a Rhodic Paleudult soil solution under natural grasses vegetation. Soybean seedlings were grown in growth chamber for three days in aerated test tubes containing 40ml soil solution (4.2µmol Al L-1, submmited to four aluminum concentrations (0.0, 0.3, 0.6 and 1.2mmol L-1 and three pH levels (4.0, 5.0 and 6.0.

    Full Text Available Aluminum (Al3+ toxicity is a major limiting factor to crop productivity in acid soils. The effects of aluminum on root and shoot growth of physic nut (Jatropha curcas L. young plants and, the uptake and distribution of phosphorus, calcium, magnesium and aluminum in the roots and shoots were investigated in the present study. Plants were grown in 2.5L pots in a greenhouse. After fourteen days of adaptation to nutrient solution, plants were exposed to Al concentrations of 0, 370, 740, 1,100 and 1,480 ?mol L–1, corresponding to an active Al3+ solution of 13.3, 35.3, 90.0, 153.3 and 220.7 ?mol L–1, respectively. The dry matter partitioning between roots, stems and leaves, and the concentrations of P, Ca, Mg and Al in plant tissue, were measured after 75 days exposure to Al. The increasing level of Al3+ activity in solution progressively decreased the growth of the shoot and root of physic nut plants, and at the two highest active Al3+ levels, plants showed morphological abnormalities typical of the toxicity caused by this metal. Higher Al3+ activity reduced P concentrations in leaves and Ca and Mg in leaves and roots of physic nut, demonstrating the effect of Al on the uptake, transport and use of these nutrients by plants. The Al accumulated preferentially in the roots of physic nut, whereas only a small amount was transported to shoots.A toxicidade de alumínio (Al3+ é um dos principais fatores que limitam a produtividade das culturas em solos ácidos.

    Full Text Available The major part of Brazilian soils shows elevated aluminum contents and in several cases this element occurs in phytotoxic levels. Aluminum is a constituent of the soil´s clay minerals. Its release can occur to the exchangeable fraction or to the soil solution. The objective of this work was to demonstrate the relationship between the spatial variability of aluminum and the distribution of soil clay. In order to achieve that, a grid of soil samples was collected in field, defined by means of photointerpretation and observation of images. The results obtained in laboratory were submitted to statistical analyses to verify spatial dependence, which was proven later. The space continuity was studied by means of the semivariogram’s elaboration using different models. The best semivariograms were chosen by cross validation performed through "ordinary kriging". Thus, it could be observed that these variables showed structure of spatial dependence, with a positive correlation between them, besides it was possible to make maps in order to allow a better agricultural exploitation.A maior parte dos solos brasileiros possui altos teores de alumínio e, em muitos casos, este elemento ocorre em níveis fitotóxicos. Constituinte dos minerais de argila, pode ter sua liberação diretamente na forma trocável ou para a solução do solo. O objetivo deste trabalho foi demonstrar a relação entre a variabilidade espacial do alumínio e a distribuição de argila do solo. Para isto, foi coletada uma malha de amostras de solo em campo, definida por meio de fotointerpretação e observação de imagens. Os resultados obtidos em laboratório foram submetidos a análises estatísticas visando a verificação da dependência espacial, que foi comprovada posteriormente. A continuidade espacial foi estudada mediante a elaboração de semivariogramas utilizando-se diferentes modelos. Os melhores semivariogramas foram escolhidos mediante a validação cruzada executada

    Full Text Available Na exploração do petróleo, o uso de fluidos de perfuração é essencial para o equilíbrio da pressão entre as formações e o interior do poço, além de impedir o refluxo do reservatório de petróleo ao poço. Os fluidos também são responsáveis pela elevação dos cascalhos de perfuração à superfície. Entretanto, estes podem ser potenciais contaminantes do ambiente, uma vez que chegam à superfície impregnados de fluidos. O trabalho objetivou avaliar o pH e os teores de Na+, K+, Ca2+, Mg2+e Al3+em um Latossolo e um Planossolo submetidos a doses de fluido de perfuração, após sofrerem dois ensaios de lixiviação. Os resultados mostraram que a adição dos fluidos ao Planossolo e Latossolo nas concentrações de 4%, 8% e 16% (m/m reduziu o alumínio tóxico a zero e promoveu aumento do pH do solo, Na+, K+e Ca2+em comparação ao controle

    Full Text Available A inovação tem sido considerada de fundamental importância para organizações que competem em ambientes dinâmicos. Verifica-se, assim, uma estreita relação entre as estratégias organizacionais e a prática da inovação. No que se refere à estratégia competitiva, sabe-se que ela pode tanto estimular quanto inibir tal prática. A estratégia de produção, por sua vez, deve estar alinhada à estratégia competitiva e ter um conteúdo (formado pelas prioridades competitivas e áreas de decisão definido de forma que sustente a posição competitiva da organização. Nesse contexto, o presente trabalho tem como objetivo analisar como a inovação tecnológica (de produto e de processo se insere no conteúdo da estratégia de produção de uma empresa produtora de alumínio da região de Sorocaba. Trata-se de uma pesquisa descritiva e exploratória, de natureza qualitativa, que utiliza o estudo de caso como método de procedimento. A empresa analisada na pesquisa está presente nos setores de metais, cimento, energia, siderurgia, celulose, agroindústria, finanças, além de investir em empresas em estágio inicial com alto potencial de crescimento. A unidade de negócios selecionada para o estudo de caso restringe sua produção a itens de alumínio, atuando nos segmentos de transporte, embalagem, eletricidade, construção civil e bens de consumo. Os resultados foram obtidos por meio de entrevistas e observações que tiveram como foco o setor de laminação da unidade em estudo. Entre as principais conclusões, verificou-se que, nesse caso, há uma maior ocorrência da inovação de processo do que da inovação de produto. Como prioridades competitivas, observou-se a ênfase nas prioridades flexibilidade e custo. A inovação não é vista na empresa como uma prioridade competitiva, no entanto constatou-se que ela ocorre muitas vezes como forma de melhor desenvolver as prioridades flexibilidade e custo.

    Full Text Available Foram instalados dois experimentos preliminares, em solução nutritiva, para avaliar a tolerância da soja ao alumínio. No primeiro, foram testados os cultivares Cristalina e UFV-1, utilizando-se os teores 0, 5, 10 e 20mg/litro de Al. Esses níveis foram muito altos e reduziram drasticamente o comprimento das raízes primarias das plântulas após sete dias de crescimento. Com base nesses dados, outro experimento foi instalado, testando os cultivares Lee, Bragg, Cristalina e UFV-1. a 0, 1, 2 e 4mg/litro de Al. Os resultados mostraram que o comprimento das raízes primárias das plântulas foi melhor parâmetro do que o peso seco da parte aérea ou das raízes, para avaliar tolerância de soja ao alumínio. O nível de 1mg/litro na solução foi suficiente para separar os cultivares susceptíveis e tolerantes, enquanto os níveis de 2 e 4mg/litro causaram drástica redução do comprimento de raiz primária das plântulas de todos os cultivares. Nessas condições, 'Lee' e 'Cristalina' mostraram ser tolerantes enquanto o 'Bragg' se apresentou intermediário e o 'UFV-1' foi o mais susceptível entre eles. Os cultivares tolerantes revelaram tendência de acumular menores teores de Al na parte aérea, em comparação com os demais.Two experiments were conducted in nutrient solution to study the level of Al necessary to separate tolerant cultivars from the susceptible. In the first experiment the levels of Al were 0, 5, 10 and 20mg/l and two cultivars Cristalina and UFV-1 were studied. These levels were found to be too high as they had drastic effect on the primary roots after 7 days of transplanting. Based on this data another experiment was conducted using 0, 1, 2 and 4mg/l of Al and using cultivars Lee, Bragg, Cristalina and UFV-1. The results showed that the length of the primary root was the best parameter as compared with dry weight of the above ground parts and roots to evaluate tolerance of soybeans to Al. The level of 1mg/l was adequate to

    Full Text Available Os lixiviados de aterros sanitários apresentam elevadas concentrações de nitrogênio amoniacal, matéria orgânica biodegradável e compostos recalcitrantes, que não permitem seu descarte no meio ambiente sem tratamento prévio. Como alternativa complementar ao tratamento biológico desse efluente, diferentes processos físico-químicos têm sido desenvolvidos para reduzir as concentrações de matéria orgânica recalcitrante presentes nos lixiviados de aterro sanitário. Para tanto, a presente pesquisa buscou avaliar a eficiência do processo de coagulação-floculação quanto à remoção dessa matéria orgânica presente em lixiviado pré-tratado biologicamente utilizando quitosana e sulfato de alumínio como coagulantes. Durante a realização dos ensaios, o efluente coletado de um sistema de lodo ativado operado em bateladas seqüenciais em escala piloto, instalado na área do Aterro Sanitário Integrado Camaçari e Dias D’avila, foi submetido ao tratamento físico-químico com os coagulantes quitosana e sulfato de alumínio (Al2(SO43.14 H2O em equipamento de testes de jarros. Para avaliar a eficiência do processo físico-químico, foi aplicada a metodologia estatística de planejamento experimental, a fim de obter as melhores condições de processo que fornecessem eficiências de remoção significativas da matéria orgânica recalcitrante por meio dos parâmetros cor verdadeira e turbidez. Posteriormente, foram realizados alguns ensaios de toxicidade aguda com Lemna minor e Poecilia reticulata. Os resultados mostraram que, nas faixas testadas, apenas as variáveis de controle concentração de coagulante (C e o valor do pH de dosagem foram significativas para o processo, uma vez que as condições de mistura (Gmr, Gf, Tmr e Tf não influenciaram nas variáveis respostas. Utilizando a quitosana como coagulante, alcançou-se valores médios de eficiência de remoção de cor verdadeira e turbidez iguais a 73% e 94

    Full Text Available Resumo A União Pontual por Fricção (FSpJ é uma técnica inovadora para união de estruturas híbridas metal-polímero e baseia-se na geração de calor por fricção. Juntas de alumínio 2024-T3 e compósito laminado de poli(sulfeto de fenileno com fibra de carbono (CF-PPS foram produzidas com filme intermediário de PPS. Duas espessuras de filme foram investigadas: 100 e 500 µm. Ensaios de cisalhamento sob tração demonstraram que as juntas com filmes de 100 µm são mais resistentes (2093 ± 180 N em relação às juntas com filme de 500 µm (708 ± 69 N. Adicionalmente, as superfícies de fratura das juntas revelaram áreas de união maiores para as juntas com filmes de 100 µm (53 ± 2 contra 40 ± 1 mm2. Para o filme mais fino, a extensão do amolecimento devido ao calor friccional é maior. Consequentemente, a baixa viscosidade atingida com a fusão do polímero favorece a molhabilidade das superfícies dos componentes da junta pelo PPS amolecido, resultando em melhor adesão entre as partes. Ademais, análises microestruturais demonstraram que a formação do cerne metálico e a interdifusão das moléculas de PPS entre compósito e filme também são favorecidas. Portanto, concluiu-se que a adição do filme mais fino produziu juntas mais resistentes.

    Full Text Available O objetivo deste trabalho foi avaliar linhas quase isogênicas de trigo com o caráter permanência verde e de maturação sincronizada quanto à tolerância ao alumínio e à sensibilidade ao ácido giberélico (AG3. O experimento foi conduzido no Laboratório de Duplo-haplóides e Hidroponia da FAEM/UFPel, em delineamento de blocos ao acaso, com parcelas subdivididas com três repetições, através do teste simultâneo utilizando solução nutritiva com concentrações de 10mg L-1 de Al3+ e 100mg L-1 de AG3. Foram determinados: a inserção da 1feminine folha, o comprimento da 1feminine folha, a inserção da 2feminine folha, comprimento da 2feminine folha, diferença da inserção entre a 1feminine e 2feminine folha, estatura de plântula, estatura de planta, área foliar, área radicular e o crescimento de raiz. Os caracteres estatura da plântula, inserção da 1feminine folha e comprimento da 2feminine folha foram os mais expressivos para a seleção de indivíduos com estatura reduzida através da reação do AG3. O grupo do caráter permanência verde apresentou maior insensibilidade à ação do AG3, enquanto o grupo de plantas sincronizadas proporcionou maior tolerância ao Al3+. Contudo, existe possibilidade de selecionar linhas quase isogênicas dentro do grupo permanência verde com tolerância ao Al3+ e insensibilidade ao AG3 através da técnica de cultivo hidropônico com solução nutritiva em ambiente controlado.

    Full Text Available Filmes de BOPP e de PET metalizados são muito utilizados em embalagens multicamadas, pois reúnem boas propriedades mecânicas e de barreira a gases e umidade, as quais, bem como a aparência e a integridade, são comprometidas quando ocorre a delaminação da estrutura multicamada. Um dos principais fatores que influem na resistência à delaminação é a força de adesão da camada de alumínio ao substrato polimérico, parâmetro para o qual não há um método de quantificação normalizado. O objetivo deste trabalho foi estabelecer e validar um método de ensaio para determinar esta força de adesão. O método foi definido usando um planejamento experimental com fatores fixos e variáveis sendo que, para cada variável, foram definidos dois níveis. O método de ensaio estabelecido mostrou-se estável, preciso, robusto e replicável. Consiste, basicamente, na termosselagem de um filme plástico à face metalizada da amostra, em condições específicas de temperatura/tempo/pressão, e medida da força para destacamento da metalização, em ângulo e velocidade específicos, em máquina universal de ensaios.OPP and OPET metallized films are widely used as substrates in multilayer packages, since they bring together good mechanical properties and barrier to gases and water vapor, which are damaged with delamination of the film layers, together with the visual appearance and package integrity. One of the main factors that affect the package delamination is the adhesion strength of aluminum layer to the polymeric substrate, a parameter for which there is no standard procedure to quantify. The aim of this work was to establish and validate a procedure to determine the adhesion strength of the aluminum to the polymer. This test procedure was carried out using experimental design with fixed and variables parameters with two levels for each variable. The test procedure was stable, robust and replicable. It consisted basically of the heat sealing

    Full Text Available Neste trabalho foi estudada a influência das características das substâncias húmicas (SH, em especial a massa molar das moléculas, na eficiência da coagulação com o uso do sulfato de alumínio. Utilizando-se de água proveniente de poço profundo, foram preparadas quatro águas de estudo, todas com cor verdadeira de aproximadamente 100 uH. As SH foram extraídas de turfa e fracionadas em massas molares: i SH filtradas em membranas de 0,45 µm; ii SH filtradas em membranas de 0,45 µm e maiores que 100 kDa, iii SH com moléculas entre 30 e 100 kDa; iv SH com moléculas menores do que 30 kDa. Verificou-se que quanto maior a massa molar das SH maior foi a eficiência de remoção da cor aparente, com as menores dosagens de coagulante.O pH de coagulação ótimo, esteve entre 6,0 e 7,0, para todas as águas de estudo. Os estudos da porcentagem de ácido húmico (AH e ácido fúlvico (AF presentes em cada fração de diferente massa molar mostraram que quanto maior foi à porcentagem de AF presente, maior foi à dosagem de coagulante exigida para se obter os melhores resultados de remoção da cor aparente.The influence of the molecular weight of soil humic substances on the coagulation efficiency with aluminum sulfate was studied in this work. Four types of water were studied, with the same true color of approximately 100 HU, but prepared with different fractions of molecular weights: Water Type 1 (humic substances filtered in membrane of 0,45 µm; Water Type 2 (humic substances filtered in membrane of 0,45 µm and with molecular weight > 100 KDa; Water Type 3 (humic substances with molecular weight between 100 and 30 KDa; Water Type 4 (humic substances with molecular weight < 30 KDa. It was conclude that the higher the molecular weight of the molecules, the lower the coagulant dosages required for efficient coagulation, at the coagulation pH range 6 - 7. The types of water prepared with the fractions of humic substances containing higher

    Full Text Available Ensaios de resistência ao desgaste, na modalidade pino-contra-disco com pares deslizantes, foram realizados em pinos confeccionados a partir de pós de alumina proveniente do processo de decomposição térmica de acetato de alumínio liofilizado. Pós de alumina referentes às fases alfa-Al2O3 e gama-Al2O3, com e sem aditivos de sinterização (MgO e La2O3, foram usados para confeccionar pinos de desgaste. Pinos feitos também a partir de alumina comercial (A1000 SG foram analisados e os resultados foram comparados. Os ensaios foram feitos de acordo com norma ASTM e mostraram que os pinos confeccionados a partir de alfa-Al2O3 têm elevada resistência ao desgaste, comprovada pelos ensaios de perda de massa e microscopia eletrônica. Os pinos de gama-Al2O3 tiveram desempenho intermediário e os pinos de A1000 SG mostraram resultados menos expressivos.Wear resistance tests, using the pin-on-disk test method with sliding pairs, were carried out on pins produced from alumina powders prepared by thermal decomposition of lyophilized aluminum acetate. Alumina powders of alpha-Al2O3 and gamma-Al2O3 phases, with and without sintering additives (MgO and La2O3, were used to produce wear pins. In addition, pins made of commercial alumina (A1000 SG were tested and the results compared. The tests, carried out according to the ASTM standard, indicated that the pins made with alpha-Al2O3 powder showed high wear resistance, a finding corroborated by mass loss tests and scanning electron microscopy. The gamma-Al2O3 pins showed an intermediary performance while the A1000 SG pins showed less interesting results.

    Full Text Available Compósitos de poliuretano e amianto (liner são utilizados como revestimento interno em paredes de motor-foguete, conferindo proteção térmica e garantindo a adesão entre o propelente e as paredes do motor. No entanto, o uso do amianto tem sido restringido devido à sua toxidade. No presente trabalho, o amianto foi substituído por um silicato de alumínio hidratado (SA e pelo grafite expansível (GE em diferentes teores no liner. Resultados de análise termogravimétrica (TG mostraram que a estabilidade térmica do liner praticamente não é afetada pela substituição das cargas, embora a energia de ativação (Ea obtida para a decomposição tenha mudado, mostrando maiores valores para as amostras contendo as cargas SA e GE. A análise termomecânica (TMA mostrou que o coeficiente de expansão térmica linear do liner contendo SA foi menor que aquele encontrado para o liner contendo amianto. O liner contendo a carga SA também apresentou os maiores valores de tensão nos testes mecânicos de tração.Composites of polyurethane (PU and asbestos (liner are used as internal coating of rocket motors, providing thermal protection and assuring the adhesion between propellant and the motor walls. However, the use of asbestos has been restricted due to its hazardous nature. In the present work, asbestos was replaced by hydrated alumina silicate (SA and expandable graphite (GE in different contents. Thermogravimetric analysis (TG showed that the thermal stability of liners was practically unaffected by the filler replacement although the activation energy obtained for the decomposition has changed. Thermomechanical analysis (TMA showed that coefficients of thermal expansion of SA/liners were lower than asbestos/liner. SA/liners also presented the highest tension values in mechanical tests.

    Full Text Available O objetivo deste trabalho é analisar em que medida o processo de terceirização em uma indústria de alumínio primário no município de Barcarena, no estado do Pará, produz diferenciações nas identidades sociais dos trabalhadores diretos e dos terceirizados. Como se sabe, os terceirizados possuem estatuto diferenciado no espaço de trabalho, o que os exclui da rede de benefícios oferecida pelas empresas. Nesse sentido, a sociedade passa a conviver não apenas com a fragilidade presente na relação salarial, mas também com o desmoronamento dos princípios reguladores da sociabilidade entre os trabalhadores. A hipótese levantada é a de que os estatutos mais precários que fundamentam a condição dos terceirizados se estendem por toda a constituição da vida social destes e lhes confere uma identidade social distinta. Foram realizadas 15 entrevistas com cada grupo de trabalhadores e duas entrevistas com dirigentes sindicais, também analisamos o acordo coletivo dos trabalhadores diretos com a empresa e os relatórios anuais desta desde o ano de 2003.This study intends to examine to what extent the outsourcing process in an industry of primary aluminum, in the city of Barcarena, Pará, results in differentiation in the social identities of direct and outsourced workers. Outsourced workers have a different status in the workplace, which excludes them from the benefits offered by the companies. As a result, society has to deal not only with the fragility of the wage relationship, but also with the collapse of the principles that regulate sociability among workers. The hypothesis is that the precarious statutes responsible for the conditions of outsourced workers are extended throughout their social lives, which gives them a distinct social identity. Fifteen interviews were conducted with each group of workers; two union leaders were also interviewed. Furthermore, the article examines the collective agreement between the direct workers

    Full Text Available Os efeitos do alumínio (Al+3 sobre a morfologia e o acúmulo de compostos fenólicos foram avaliados em duas cultivares de sorgo (Sorghum bicolor (L. Moench com tolerância diferencial ao Al+3. As plantas foram mantidas em solução nutritiva durante dez dias, na presença (185 mM ou na ausência de Al+3. Os ápices radiculares foram coloridos com hematoxilina férrica, sendo a intensidade da coloração observada na presença do Al+3 muito próxima entre as cultivares, o que inviabiliza a aplicação desse teste, isoladamente, para discriminação entre o genótipo sensível e o tolerante ao Al+3. As análises da morfologia externa e interna dos ápices radiculares de plantas tratadas com Al+3 também foram muito similares entre as duas cultivares, não permitindo a utilização dessas características para seleção entre a cultivar sensível e a tolerante. O maior acúmulo de lignina e, principalmente, a menor produção de compostos fenólicos, observados na presença do Al+3 nas raízes das plantas da cultivar tolerante (BR006R, são parâmetros que possibilitam a discriminação das cultivares quanto à tolerância ao Al+3.The Al+3 effects on the morphology and on the phenolics accumulation were evaluated in two sorghum cultivars exhibiting differential tolerance to Al+3. The plants were kept in nutrient solution, for ten days, in the presence (185 mM or Al+3 absence. The root apexes were colored with ferric hematoxylin, and because the intensity of color development is very similar among evaluated cultivars, the use of this method as a selection parameter for Al+3-tolerance is not indicated. Analyses of superficial and internal morphology from tissues treated with Al+3 also expressed very similar alterations among the two cultivars, not allowing its use for selection between sensitive and Al+3-tolerant genotype. The higher lignin accumulation and, mainly, the lower phenolics production in roots of the BR006R cultivar in Al+3's presence

    Full Text Available Resumo Este projeto trata da validação de um sistema recém desenvolvido para a soldagem pelo processo friction stir welding, que foi adaptado a um robô antropomórfico com capacidade de 500 kg e seis graus de liberdade. Para garantir que o sistema projetado é capaz de soldar materiais pelo processo FSW, ou seja, garantir que possui rigidez, resistência e torque suficientes para realizar a operação de soldagem, faz-se necessário realizar a validação do mesmo. Para tanto, foi necessário soldar um material conhecido, com parâmetros já estabelecidos, e utilizar uma ferramenta apropriadamente dimensionada. Dessa forma, escolheu-se a liga 5052 H43 de 3 mm de espessura, usada na produção de navios, embarcações e estruturas automotivas. Para a soldagem das juntas finais foi usada uma ferramenta fabricada em AISI H13, com pino cônico liso e diâmetro do ombro de 18 mm. A velocidade rotacional da ferramenta foi mantida constante em 378 rpm, e a velocidade de avanço em 7,5 mm/min, sendo a inclinação da ferramenta de 2°. Verificou-se após os ensaios que o sistema de soldagem projetado se mostrou eficaz em aplicações de soldagem FSW, apresentando torque e resistência mecânica suficientes para a união de materiais com baixo ponto de fusão. Por meio dos parâmetros utilizados, bem como da geometria da ferramenta, foi possível obter juntas da liga de alumínio 5052 H34 soldadas com: bom aspecto superficial, baixos valores de rebarba, ausência de sulcos ou vazios ao longo da linha de soldagem e com penetração total.

Em solos ácidos, vinte linhagens e o 'BH-1146' mostraram maior rendimento de grãos em relação ao 'Siete Cerros' indicando que a toxicidade de alumínio foi um dos principais fatores limitantes à produção. Em solos corrigidos, não se verificaram diferenças significativas entre os genótipos estudados quanto ao rendimento de grãos, mostrando não haver urna associação entre baixa produtividade e tolerância ao A1(3+ nessas condições. A linhagem 21 foi moderadamente resistente ao agente causal de oídio em condições naturais de infecção. Todos os genótipos avaliados revelaram suscetibilidade aos agentes causais das manchas foliares.

O estudo mostrou que um aumento na razão microsílica/cimento melhora as propriedades mecânicas e físicas do concreto, mas às custas da resistência à corrosão. Quando um teor fixo de BaSO4 foi adicionado ao material refratário base, observou-se um aumento de barium celsian junto com a formação de uma fase vítrea com o aumento da razão microsílica/cimento no refratário. Foi observado que a presença de fases vítreas diminui o efeito positivo da formação Ba-celsian na melhora da corrosão à resistência do refratário. Os resultados observados foram validados por meio de cálculos termodinâmicos que indicaram que a fase Ba-celsian era mais resistente que a Ca-anortita para aplicações envolvendo contato com alumínio líquido.

Depois de 21 dias de crescimento, foram determinados o comprimento, a produção de matéria seca, os teores de Al e de nitrato e a atividade in vitro da redutase do nitrato (RN, nas raízes e na parte aérea, bem como as constantes cinéticas de absorção de nitrato pelas raízes. O Al reduziu o crescimento em comprimento e a produção de matéria seca, nas duas partes das plantas, apenas da cultivar Maravilha. Os teores de Al aumentaram nas raízes e parte aérea das plantas nas duas cultivares, enquanto o teor de nitrato sofreu redução apenas nas raízes da cultivar Maravilha. A Vmax não se modificou, enquanto o Km da absorção de nitrato diminuiu cerca de 11% na cultivar Fernandes e aumentou 310% na Maravilha. Em presença de Al, houve redução na atividade da RN nas raízes das duas cultivares, e na parte aérea apenas da cultivar Maravilha. A cultivar tolerante foi mais eficiente na absorção e na redução de nitrato, o que indica que esses processos são importantes componentes da tolerância ao Al em arroz.The objective of this work was to evaluate the effects of Al on the nitrate uptake and reduction in two rice cultivars, Fernandes (Al tolerant and Maravilha (Al sensitive, exposed to 0 and 500 µM Al.

There are several ways of treatment for such condition, including the low intensity lasers. The proposal of this study was to verify the effectiveness of the Gallium-Aluminum-Arsenide diode laser in the treatment of this painful condition, using a placebo as control. MATERIALS AND METHODS: Thirty-two patients were selected, 22 females and 10 males, with ages ranging from 20 to 52 years old. The 32 patients were randomly distributed into two groups, treated and control; the sample consisted of 68 teeth, 35 in the treated group and 33 in the control group. The treated group was exposed to six laser applications with intervals from 48 to 72 hours, and the control group received, as placebo, applications of a curing light. RESULTS: A significant reduction was observed in the pain condition between the initial phase and after six laser applications; however, such reduction could also be observed for the control group exposed to the placebo. CONCLUSION: Therapy with the low intensity Gallium-Aluminum-Arsenide laser - AsGaAl induces a statistically significant reduction in the painful condition after each application and between the beginning and end of treatment, although there was no statistically significant difference between the treated group (laser and the control group (placebo at the end of treatment and after the mediate evaluation results (after 6 weeks, this way impairing the real measurement of laser effectiveness and placebo effect.A hiperestesia dentinária trata-se de uma condição dolorosa bastante prevalente nas populações mundiais.

  14. Alfvén Waves and the Aurora (Hannes Alfvén Medal Lecture)

    Science.gov (United States)

    Lysak, Robert

    2015-04-01

    The most compelling visual evidence of plasma processes in the magnetosphere of Earth as well as the other magnetized planets is the aurora. Over 40 years of research have indicated that the aurora is a consequence of the acceleration of charged particles toward the neutral atmosphere, where the excitation of neutral atoms and their subsequent relaxation to the ground state produces the auroral light. Much of this acceleration can be described by acceleration in a quasi-static electric field parallel to the geomagnetic field, producing nearly monoenergetic beams of electrons. While a variety of quasi-static models to describe such parallel electric fields have been developed, the dynamics of how these fields evolve is still an open question. Satellite measurements have indicated that a primary source of energy to support these fields is the Poynting flux associated with shear Alfvén waves propagating along auroral field lines. These Alfvén waves are generated in the magnetosphere and reflect from the ionosphere. On closed field lines, Alfvén waves bouncing between conjugate ionospheres produce field line resonances that have be observed both in space and by ground magnetometers. However, some auroral emissions do not follow this scenario. In these cases, the accelerated electrons are observed to have a broad energy spectrum, rather than a monoenergetic peak. Such a spectrum is suggestive of a time-dependent acceleration process that operates on a time scale of a few seconds, comparable to the electron transit time across the acceleration region. While field line resonances have a time scale on the order of minutes, waves with periods of a few seconds can be produced by partial reflections in the Ionospheric Alfvén Resonator, a resonant cavity formed by the rapid decrease of the plasma density and increase of the Alfvén speed above the ionosphere. In order to develop a parallel electric field that can accelerate auroral particles, these Alfvén waves must develop small spatial scales, where MHD theory breaks down. In this regime, the waves are called kinetic Alfvén waves. These small scales can be produced most simply be phase mixing, although ionospheric feedback and nonlinear effects may also be important. Since kinetic Alfvén waves require perpendicular wavelengths the order of a few kilometers, this model also provides a natural explanation of the narrow scales of discrete auroral arcs. These interactions between magnetosphere and ionosphere and the development of parallel electric fields have been described by means of numerical simulations that serve to illustrate these complex processes.

Plântulas representando os pais, as gerações F1 e F2 e os retrocruzamentos para ambos os pais foram testados para a reação a 6mg/litro de Al3+ em solução nutritiva. As plantas, devidamente identificadas, foram transplantadas em número de quatro por vaso, empregando-se no total 500 vasos dispostos em quatro blocos ao acaso. Os dados referentes à produção de grãos e a outros caracteres agronômicos foram obtidos de plantas individuais. Os valores da herdabilidade no sentido restrito para comprimento da espiga, número de grãos por espiga, peso de cem grãos e altura da planta foram 0,885; 0,748; 0,760 e 0,720 respectivamente, e de 0,413 e 0,588 para número de espigas por planta e de espiguetas por espiga.

    Full Text Available Chromium and potassium-doped iron oxides are widely used as industrial catalysts in the dehydrogenation of ethylbenzene to produce styrene. They have several advantages but deactivate with time, because of the loss of potassium. Also, they are toxic due to chromium compounds. Therefore there is a need for developing alternative non toxic catalysts without potassium. Then, iron and aluminum compounds were prepared by different methods in this work. Different phases were produced depending on the preparation method. Aluminum-doped hematite was more active and selective to styrene than the aluminum ferrite. Aluminum acts both as textural and structural promoter in the catalysts.

    Full Text Available The Student from Prague  (1913 is considered to be the first  film d’art produced in Germany. The film is based on a script by Ha nns Heinz Ewers, writer and ardent advocate of this new medium. With roots in German romantic ism, particularly in regard to motifs in the works by E.T.A.

  16. The application of thermal analysis to the hydration and conversión Reactions of calcium alumínate Cements

    Directory of Open Access Journals (Sweden)

    Bushnell-Watson, S. M.

    1992-12-01

    Full Text Available The hydration of calcium aluminates cements is dominated by that of CA, CaAl2O4, which is a major constituent of all of them. At ambient temperatures, CAH10 and an amorphous phase are formed initially, but these are metastable and slowly (or more rapidly if exposed to higher temperatures transform into C3AH6 and gíbbsite. This conversion reaction is accompanied by and increase ín porosity, which can lead to a loss in strength and vulnerability to chemical attack. Various methods of thermal analysis have been applied as a routine test to determine the degree of conversion, and the results from these methods are critically evaluated. Thermal analysis is a useful technique for identification of the various hydrates that can form in these systems, especially at early stages of hydration when poorly crystalline phases are present. Differential thermal analysis curves showing peaks attributable to all these hydrates are presented and it is shown that overlap frequently occurs, leading to difficulties in interpretation, which can sometimes be minimized by use of a complementary technique such as X-ray diffraction.

    La hidratación de cementos aluminosos está regida por la de CA, CaAl2O4, que es el componente principal. A temperatura ambiente inicialmente se forman CAH10 y una fase amorfa, pero son metaestables y se transforman lentamente (o más rápidamente si se exponen a temperaturas más altas en C3AH6 y gibsita. Esta reacción de conversión está acompañada de un aumento de porosidad, lo que lleva a la pérdida de resistencia y a la vulnerabilidad al ataque químico. Se han aplicado distintos métodos de análisis térmico como una prueba rutinaria para determinar el grado de conversión y se ofrece una evaluación crítica de los resultados de estos métodos. Análisis térmico es una técnica útil para identificar los distintos hidratos que pueden formarse en estos sistemas, especialmente en las etapas iniciales de la hidratación cuando están presentes las fases pobremente cristalinas. Se presentan curvas diferenciales de análisis térmico que muestran picos atribuibles a todos estos hidratos y se demuestra que, frecuentemente, ocurre superposición que produce dificultades en interpretación, las que a veces pueden hacerse menores utilizando técnicas como la difracción de rayos X.

    Full Text Available A macieira (Malus sp. cultivada em solos ácidos com pH inferior a 5,0 pode apresentar distúrbios nutricionais e inibição de crescimento causados por níveis tóxicos de Al que podem afetar a absorção do Ca, o qual apresenta estreita correlação com a produção de frutos de melhor qualidade. O objetivo deste trabalho foi verificar a tolerância ao Al em 18 somaclones e três cultivares porta-enxertos provenientes da seleção in vitro. As plântulas foram cultivadas durante 45 dias em copos de plástico de 300 mL contendo solução nutritiva e utilizando-se sílica lavada como substrato. Os valores obtidos foram submetidos à análise multivariada pelos componentes principais e agrupamento hierárquico baseado no método de Ward, o qual revelou ser mais adequado na classificação dos clones quanto à tolerância ao Al do que os testes de médias. O porcentual de redução na matéria seca da parte aérea e no número de folhas foram características que melhor possibilitaram a discriminação dos clones. Os clones foram classificados em três grupos: bem sensível ou não tolerante, moderadamente tolerante e tolerante.

  18. Origen de arcillas alumínicas en horizontes de alteración de materiales graníticos del borde sur de la sierra de Guadarrama

    Directory of Open Access Journals (Sweden)

    Martín Patino, M. T.

    1988-08-01

    Full Text Available Three weathering profiles of granitic rocks and two arkoses in the NW of Madrid Province have been studied. Rocks are granodiorites and adamellites with albites showing variable degrees of sericitization, and no-weathered potassic feldspars. Clay fraction in the weathered horizons from these rocks displays high content in beidellite, and minor amounts of illite and 7 Ǻ-halloysite. On the other hand, beidellite, illite and well crystallized kaolinite are clay minerals in the arkosic rocks. Microfabric characteristics from SEM studies show abundant weathered albites with clean surfaces and formation of beidellite in all areas of the samples. Moreover, spatial relations between albite and beidellite are not observed. In pedochemical weathering of albite, sodium from this mineral should be exchanged with protons from soil solution with very quick kinetics. This initial alkalinization produces an increase in the silica solubility released from albite network. In these environments, a continued contact between weathering solution and albite causes a silica and alumina enrichment and beidellite or 7 Ǻ-halloysite precipitation. Microclimatic variations in weathering environment may cause fluctuations in silica and alumina activities with resultant pH changes. So, when silica activities are high, beidellite neoformation is favoured; on the contrary, 7 Ǻ-halloysite is precipitated.Se han estudiado tres perfiles de alteración de rocas graníticas y dos muestras de arcosas en la zona NO de la provincia de Madrid. Las rocas, clasificadas como granodioritas y adamellitas, presentan albitas con sericitización variable, y escasos feldespatos potásicos muy poco alterados. La fracción arcilla de los horizontes de alteración de estas rocas presenta un alto contenido en beidellita, así como porcentajes menores de ilita y haloisita-7Ǻ. Por otra parte, los minerales de la arcilla presentes en las arcosas son ilita, beidellita y caolinita bien cristalizada. El estudio de la microfábrica muestra la presencia de albitas alteradas con superficies limpias y beidellita de neoformación en cualquier zona de la muestra sin ningún tipo de relación espacial con la albita. En la alteración edafoquímica de la albita, el sodio de este silicato se intercambiaría con protones procedentes de la fase acuosa, con una cinética muy rápida. Esta alcalinización inicial daría lugar a un aumento en la solubilidad de la sílice liberada a partir de la red de las albitas. En aquellos microambientes en los que se produce un prolongado contacto entre la solución de alteración y la albita, la primera puede enriquecerse suficientemente en sílice y alúmina como para alcanzar la precipitación de beidellita o haloisita-7Ǻ. Las variaciones en las condiciones microclimáticas del medio de alteración deben producir fluctuaciones en las actividades de sílice y alúmina, con cambios de pH suficientes como para dar Jugar a la neoformación de beidellita cuando las actividades de sílice sean elevadas y, de haloisita-7Ǻ en caso contrario.

  9. Contribution of U-Pb geochronology to characterizing the Cadomian magmatism of the southeastern French Massif Central and of the related uranium-ore at Bertholene

    International Nuclear Information System (INIS)

    Leveque, Marie-Helene

    1990-01-01

    U-Pb geochronology and whole-rock geochemistry (major, trace and rare earth elements) were applied to various ortho- and paragneiss formations of the southeastern part of the French Massif Central. The Mendic granite and the Les Palanges granite were dated at 603 ± 9 Ma and 540 ± 18 Ma, respectively. Their micaschist host-rocks show a multi-episodic evolution that matches the U-Pb data obtained on metasediments and leucogranites of the Variscan Orogen. An old zircon source was detected at 1.87 Ga in the Les Palanges micaschist, while, seemingly, this heritage was wiped out of the Mendic micaschist during the Cadomian events. In the Decazeville gneiss, where a crustal component of unknown age has been detected, the major event is the Variscan migmatization. At Bertholene, the geochronology of uranium ores associated to the Les Palanges orthogneiss evidenced two periods of emplacement: -the relicts of the first phase, of Liassic age at 173 ± 9 Ma, are restricted to an uranium oxide; -the second phase, related to coffinites, represents the economical ore emplaced from Oligocene until Recent times, generated through remobilization of the Liassic stock. A comparison between the geochronological data from the ore, and of those from its granite host, suggests a genetic relationship between the Cadomian magmatism and the U-concentrations, spatially linked to the unconformity between the Les Palanges basement and its Permo-Carboniferous cover series. Metamictization of the source minerals combined with tectonic processes would be responsible for the release of uranium. Uranium-rich minerals from Bertholene, from Lodeve and from Les Pierres-Plantees have been subjected to trial dating by the isotopic Xe-Xe method, which confirms the evolution admitted for those occurrences. This technique is demonstrably expeditious and faithful. Various phenomena were investigated, at the scale of the crystalline structure, related to the xenon energy states and to the problem of rare

    Full Text Available Metagabbro, metadiabase and metabasalt of the Chah Palang and Me'raji mountains associated with Lower Paleozoic metamorphites are situated in the south of Arousan. Metabasites of these areas are relatively similar in terms of mineralogy and geochemical characteristics. Rock-forming minerals of the Me'raji metabasites are feldspar, amphibole, biotite, sphene, epidote, chlorite ± calcite. Metagabbro and metadiabase of the Chah Palang area are similar to the Me'raji metabasites in mineralogy and geochemistry. Volcanic rocks are overlain by metagabbros and consist of plagioclase, biotite, sphene, sanidine, chlorite, epidote and iron oxides. The rigid dykes, which are found in the volcanic units are associated with metagabbros and mineralogically are similar to the metavolcanics. Amphibolitic dykes are composed of amphibole, plagioclase and biotite with preferred orientation. Metabasites show limited range of differentiation. Me'raji metabasites are basalt and trachy-basalt in composition, whereas the Chah Palang ones present basalt and trachy-basalt composition. Similar to metabasites of the other parts of Iran, the studied basic rocks demonstrate alkaline to transitional chemical characteristic and are formed in an extensional environment by low-degree partial melting of a garnet-spinel peridotite. Metamorphic episodes have changed the studied rocks to amphibolite and greenschist, but the primitive igneous textures are preserved.

    Full Text Available The most common difficulties which occur in trace analysis are those which involve contamination, mainly when the measurement is at very low concentration of ubiquitous elements as aluminium. The worst situation is when a separation step is necessary, because it requires extra-manipulations of the sample.

    Full Text Available Em solos ácidos de ambiente mais tropical com esmectitas, assim como em solos altamente tamponados de ambiente subtropical, contendo esmectita com hidroxi-Al entrecamadas (EHE e, ou, vermiculita com hidroxi-Al entrecamadas (VHE, os teores de Al-KCl podem ser excepcionalmente altos; entretanto, em alguns casos não se manifestam efeitos fitotóxicos do elemento nas culturas. O Al "trocável" é tradicionalmente quantificado no extrato da solução de KCl 1 mol L-1 (Al-KCl, mas nem sempre esse elemento provém unicamente de formas trocáveis. Este trabalho objetivou investigar relações entre o Al extraído com solução de KCl e de oxalato de amônio com a mineralogia da fração argila. A quantificação do Al nos extratos de KCl e oxalato de amônio foi feita, respectivamente, por titulação com NaOH 0,02 mol L-1 padronizado e por espectrofotometria de absorção atômica. Foram utilizadas amostras de dois horizontes (A e B de 12 perfis de solo de cinco estados brasileiros (AC, PE, BA, RS e SC, com diferentes características mineralógicas, todos com teores de Al-KCl superior a 4 cmol c kg-1 no horizonte B. Dois perfis de SC (Rancho Queimado e Curitibanos, com níveis mais baixos de Al-KCl, foram incluídos para comparação. Os altos teores de Al-KCl evidenciaram-se relacionados com a mineralogia dos solos estudados. Nos solos ácidos com mais esmectitas, drenagem moderada ou imperfeita e oscilação do lençol freático houve evidências morfológicas, confirmadas pelas análises mineralógicas, de que no clima atual ocorre um processo de destruição de argilas, liberando Al que precipita como compostos amorfos. A alta concentração salina da solução de KCl dissolve parcialmente tais compostos, superestimando as formas trocáveis desse elemento, principalmente nos horizontes subsuperficiais. Nos solos ácidos do ambiente subtropical, os teores de Al-KCl também foram altos, embora com valores mais baixos do que nos com predomínio de esmectitas. Parte do Al-KCl nesses solos parece provir da dissolução de compostos orgânicos e de Al presente em entrecamadas de argilominerais 2:1. Os resultados demonstraram que o KCl 1 mol L-1 não foi adequado para estimar o Al "trocável" na maioria dos solos estudados.

    Full Text Available Este trabalho teve por objetivo determinar a influência do Al sobre a composição de ácidos graxos em raízes de duas cultivares de sorgo [Sorghum bicolor (L. Moench] com tolerância diferencial ao Al. Após exposição das plantas ao Al, raízes foram coletadas, os lipídios extraídos e determinada sua composição em ácidos graxos. O palmítico e, especialmente, o linoléico foram os principais ácidos graxos identificados nos extratos lipídicos de raízes das duas cultivares, independentemente da presença do Al. Nas plantas tratadas com Al, os teores dos ácidos esteárico e oléico aumentaram apenas na cultivar tolerante, mas os teores do ácido linolênico reduziram nas duas cultivares. Essas alterações na composição de ácidos graxos, o índice de ligações duplas para ácidos graxos contendo 18 carbonos (ILD C18 e as relações ácidos graxos saturados/ácidos graxos insaturados (AGI/AGS e ácido linoléico/ácido palmítico (18:2/16:0 sugerem que ocorre redução na fluidez dos lipídios da cultivar tolerante, porém aumento na sensível. A redução na fluidez dos lipídios na cultivar tolerante, comparativamente à da sensível sugere ter a cultivar tolerante maior capacidade de reter íons e metabólitos essenciais e, ou limitar a entrada do Al em suas raízes.The objective of this work was to determine Al effect on fatty acid composition of roots from two sorghum (Sorghum bicolor (L. Moench cultivars with differential tolerance to aluminum. After exposure to Al, roots were collected, lipids extracted and the fatty acid composition determined. Palmitic and, especially, linoleic acid were the major fatty acids identified in the root lipid extracts of both cultivars, regardless of the presence of aluminum. Stearic and oleic acids contents increase only in the tolerant cultivar, while linolenic acid decreased in both cultivars after Al treatment. These changes in fatty acid composition, as well as in the C18-fatty acid double bound index (DBI C18 and in the ratios of unsaturated fatty acid/saturated fatty acid (UFA/SFA and linoleic acid/palmitic acid (18:2/16:0 indicated of a reduction of the lipid fluidity of the tolerant cultivar, but an increase in the sensitive one. The observed reduction in lipid fluidity in the tolerant relative to the sensitive cultivar suggests of a better capacity of the tolerant cultivar to retain essential ions and metabolites and/or to limit the entry of toxic Al ions into roots.

    Full Text Available The construction and analytical evaluation of a coated graphite Al(III ion-selective electrode, based on the ionic pair formed between the Al(Fn3-n anion and tricaprylylmethylammonium cation (Aliquat 336S incorporated on a poly(vinylchloride (PVC matrix membrane are described. A thin membrane film of this ionic pair and dibutylphthalate (DBPh in PVC was deposited directly on a cylindric graphite rod (2 cm length x 0.5 cm diameter attached to the end of a glass tube using epoxy resin. The membrane solution was prepared by dissolving 40% (m/m of PVC in 10 mL of tetrahydrofuran following addition of 45% (m/m of DBPh and 15% (m/m of the ionic pair. The effect of membrane composition, fluoride concentration, and several concomitants as potential interferences on the electrode response were investigated. The aluminium(III ion-selective electrode showed a linear response ranging from 1.4 x 10-4 to 1.0 x 10-2 mol L-1, a detection limit of 4.0 x 10-5 mol L-1, aslope of -54.3±0.2mV dec-1 and a lifetime of more than 1 year (over 3000 determinations for each membrane. The slope indicates that the ion-selective electrode responds preferentially to the Al(F4- species. Application of this electrode for the aluminium(III determination in stomach anti-acid samples is reported.

    Four coal-based media, viz. alum-pretreated or ferric hydroxide-impregnated Giridih bituminous coal and lignite (alum-GBC, Fe-GBC; alum-lignite and Fe-Lignite) were laboratory tested to assess their potential in removing/inactivating enteric viruses in water. Batch-sorption screening tests, employing a poliovirus-spiked canal water, indicated high poliovirus sorption by Fe-GBC and alum-GBC in a short contact time of 5 min. Based on the results of further batch-sorption tests, using silver incorporated media (alum/Ag-GBC, alum-GBC-Ag and Fe-GBC-Ag), as well as aesthetic water quality consideration and previous findings on removal of coliforms and turbidity, alum/Ag-GBC, alum-GBC and alum-GBC-AG were included in downflow column studies employing poliovirus-spiked canal water. All three media showed potential in removing/inactivating enteric viruses. In a separate column study employing a joint challenge of poliovirus and rotavirus, alum/Ag-GBC removed 59.3-86.5% of the viruses along with more than 99% reduction in indigenous heterotrophic bacteria. Alum/silver-pretreated bituminous coal medium appears promising for use in household water filters in rural areas of the developing world. However, improved medium preparation to further enhance its efficiency is needed; also, its efficacy in removing/inactivating indigenous enteric bacteria, viruses and protozoa has to be ensured and practicalities or economics of application need to be considered.

    Full Text Available Donor darah merupakan kegiatan kemanusiaan yang bertujuan untuk membantu anggota masyarakat yang membutuhkan darah. Kegiatan donor darah diselenggarakan dan dikelola oleh Palang Merah Indonesia. Menurut catatan Palang Merah Indonesia, secara keseluruhan kebutuhan kantung darah yang tidak terpenuhi melebihi satu juta kantung darah. Untuk itu dibutuhkan peningkatan produksi kantung darah. Salah satu solusi yang dapat dilakukan adalah perancangan suatu sistem informasi geografis (GIS yang memudahkan pendonor untuk mendonorkan darahnya kembali dengan reminder donor darah dan membantu PMI mendapatkan kantung darah. Makalah ini membahas perancangan sistem reminder donor darah dengan menggunakan teknologi location based service. Kemudian untuk menguji sistem, dibuatkan sebuah prototype dengan hasil pengujian sistem menunjukkan bahwa sistem reminder donor darah dapat memudahkan pendonor dalam mendonorkan darahnya kembali sehingga memberikan motivasi bagi pendonor untuk lebih giat dalam mendonorkan darahnya. Sistem ini berpotensi meningkatkan produktivitas PMI dalam mengumpulkan kantong darah sehingga pemenuhan kebutuhan kantung darah masyarakat dapat meningkat yang pada akhirnya dapat menyelamatkan lebih banyak nyawa manusia khususnya di Indonesia.

    Full Text Available Com o objetivo de avaliar o potencial de acumulação de flúor e o percentual deste elemento removido pela lavagem, quatro espécies de hortaliças foram expostas em área poluída. Spondias dulcis foi utilizada como bioindicadora de reação e apresentou sintomas típicos em resposta ao poluente. Somente a salsa apresentou sintomas. Apesar de aparentemente sadias, as folhas das outras espécies utilizadas para estudos microscópicos, exceto da cebolinha, evidenciaram alterações na superfície, principalmente associados aos estômatos. Houve redução na espessura do limbo, mais acentuada no manjericão e na cebolinha, havendo formação de tecido de cicatrização na couve e condensação do conteúdo das células epidérmicas na salsa. As folhas subuladas e eretas da cebolinha favoreceram o menor acúmulo do poluente; já na salsa, as folhas laminares, recortadas e paralelas ao solo contribuíram para a maior retenção. A lavagem das folhas removeu 34,1 e 73,9% do flúor na cebolinha e na salsa, respectivamente, indicando que a maior parte do poluente encontrava-se internamente na cebolinha e externamente na salsa. O cultivo destas hortaliças em áreas poluídas por flúor é inadequado, pois os teores do poluente estão acima do recomendado para o consumo, mesmo após a lavagem das folhas.To assess fluoride accumulation potential and the percentage of fluoride removed by washing, four herb species were exposed to a polluted area. Spondias dulcis was used as a responsive bioindicator and showed typical fluoride response symptoms. Symptoms were observed only in parsley. Although apparently healthy, the leaves of the remaining herbs, except for chives, showed surface damage associated mainly with stomata when observed under the microscope. A reduction in leaf thickness was also observed, most prominently in basil and chives. Scar tissue was observed in kale, and a retraction of the protoplast of the epidermal cells was observed in parsley. The subulate, erect leaves of chives accumulated less fluoride; on the other hand, parsley leaves are laminar, lobed and parallel to the soil, which contributed to higher pollutant retention. Washing the leaves removed 34.1 and 73.9% of the fluoride on chives and parsley, respectively, indicating that for chives, most of the pollutant was found inside the leaves, while for parsley, the pollutant was located on the outside. Growing these herbs in fluoride-polluted areas is not recommended, since pollutant percentages are above levels recommended for consumption, even after washing the leaves.

The acidification of acid sulphate soil has as a result thesolubilization of Al compounds, which increases the concentrationof Al3+ in the soil solution. This study was carried out to evaluatethe levels of exchangeable and active Al extracted with 12analytical methods, in soil samples from acid sulphate soil fromBrazil and Colombia. It was conducted an laboratory investigationwith 12 samples soils, nine from Espirito Santo State (Brazil andthree from Colombia. The methods evaluated were: KCl 1 mol L-1,Ca(OAc2 0.5 mol L-1 pH 7, BaCl2 0.1 mol L-1, NH4OAc 1 mol L-1pH 4.8, CuCl2 0.5 mol L-1 pH 2.8 e LaCl3 0.33 mol L-1 pH 4.0. Forcomparison of extraction methods, the treatments were set as afactorial 12x12 design, arranged in a randomized block with threereplications. The analysis of variance, statistics descriptive andcontrasts were applied to determine the capacity of Al extractionby the chemical methods. The quantitative determination showedthat the method with higher extraction capacity of Al was theNa4P2O7 solution. The methods that use chloride ions unbuffered,are able to extract more efficiently the Al of the acid sulphate soilthan the solutions of acetates, being the CuCl2 and LaCl3 the oneswith highest efficiency.

    Full Text Available The flocculation and sedimentation of recalcitrant organic compounds of high molecular weight using natural polyelectrolytes, extracted from the cactus Cereus peruvianus and Opuntia ficus indica, have been studied. Organic compounds of high molecular weight from effluents of paper and pulp industries are difficult for biological degradation. However, using a mixture of aluminum salts and natural polyelectrolytes, the aggregation and settling properties of recalcitrant organics were increased if compared with conventional methods of wastewater treatment using only aluminum or iron sulfate. After flocculation, sedimentation, and filtration, the effluent was submitted to biological degradation by activated sludge process. The main advantages of using a mixture of aluminum salts and natural polyelectrolytes were shorter time of flocculation, floccus of larger size and easier for filtration.The removal efficiency observed were:85-90% of aromatic compounds, 70-85% of chemical oxygen demand,and 91-97% of colour.

  17. A study on aluminum determination in environmental samples by Neutron Activation Analysis; Estudo sobre determinação de alumínio em amostras ambientais pelo método de análise por ativação com nêutrons

    Aluminum determinations are of great interest since this element is toxic to humans and it is widely distributed in the environment. Besides, the determinations of this element by conventional analytical methods present difficulties due to sample contamination during the analyses. Neutron activation analysis (NAA) for Al determination presents advantages of fast analyses and of high sensitivity. However, NAA of Al does present problems of P and Si nuclear reaction interferences. Aluminum is determined by measuring {sup 28}Al, formed in the reaction {sup 27}Al (n, γ) {sup 28}Al, the same radioisotope formed in reactions {sup 31}P (n, α) {sup 28}Al and {sup 28}Si (n, p) {sup 28}Al. The purpose of this study was to determine Al in environmental samples by NAA correcting these interferences using correction factors, and determining P and Si concentrations in the samples. In this study, certified reference materials and biomonitor samples (tree barks and lichen) were analyzed. Experimental procedure consisted of irradiating an aliquot of the sample at the IEA-R1 nuclear research reactor together with Al standard, followed by gamma ray spectrometry. Phosphorus was determined by measuring beta radiation of {sup 32}P using a Geiger-Müller counter. Silicon was determined by epithermal neutron activation analysis and measuring {sup 29}Al formed in the reaction {sup 29}Si (n, p){sup 29}Al. Results obtained in the determination of Al, P and Si in the certified reference materials showed good precision and accuracy with |Z-score| ≤ 2. Aluminum results in the biomonitor samples varied from to 253 to 15783 μg g{sup -1}. In the case of P its concentrations varied from 283 to 1946 μg g{sup -1}. Silicon determinations in biomonitors varied from 0.11 to 7.8 %. The interference contribution rates in the analyses of the biomonitor samples were of the order of 2.0 % and this contribution depends on the relation between concentrations of interfering elements and of Al in the sample. Detection limit values of Al in the biomonitor analyses were lower than their concentrations in the samples demonstrating that the proposed procedure of NAA can be applied in the Al determination in this kind of matrix.

    Full Text Available Atualmente, alguns laboratórios de análise de solo determinam Al, Ca e Mg trocáveis em extratos de KCl 1 mol L-1 e K e Na na solução extratora Mehlich-1, também usada na extração de fósforo. Outros laboratórios, que empregam a resina trocadora de ânions para P, avaliam também Ca, Mg e K no extrato, não sendo possível determinar Al e Na. Dessa forma, achou-se oportuno avaliar a extração com NH4Cl 1 mol L-1 na determinação simultânea dos cinco cátions trocáveis: Al, Ca, Mg, K e Na, em comparação aos extratores KCl e Mehlich-1. Utilizaram-se amostras coletadas em áreas de cultivo de fruteiras irrigadas da região Nordeste e na área experimental da Embrapa Meio Ambiente em Jaguariúna (SP. Os métodos utilizados foram: (a extração simultânea dos cinco cátions com NH4Cl 1 mol L-1, e (b extração de Ca, Mg e Al com KCl 1 mol L-1, e de K e Na com o extrator Mehlich-1. A solução de NH4Cl 1 mol L-1 apresentou maior capacidade de extração de Mg do solo do que a solução de KCl 1 mol L-1; as duas soluções se equivaleram quanto à capacidade de extração de Ca e de Al. A solução de NH4Cl extraiu mais K e Na do que a solução Mehlich-1. Conclui-se que a solução de NH4Cl é uma opção conveniente para a extração de Al, Ca, Mg, K e Na trocáveis do solo.Currently, part of the soil testing laboratories of Brazil determine exchangeable Al, Ca, and Mg in a 1 mol L-1 KCl soil extract and exchangeable sodium and potassium in the Mehlich-1 soil extract, which is also used for phosphorus extraction. Other laboratories use an anion exchange resin for P and also determine Ca, Mg and K in the same extract, while Al and Na cannot be determined. For this reason, it was considered a good opportunity to evaluate the simultaneous extraction of the five exchangeable cations: Al, Ca, Mg, K, and Na in a 1 mol L-1 NH4Cl solution, and compare the results with those obtained with potassium chloride and Mehlich-1 extractants. The soil samples used were from Northeastern Brazil fruit growing region and from the Embrapa Environment Experimental Station, located in Jaguariúna County, São Paulo State. The employed methods were: (a simultaneous extraction of the five cations with a 1 mol L-1 NH4Cl; (b extraction of Ca, Mg, and Al with 1 mol L-1 KCl; and (c extraction of K and Na with the Mehlich-1 solution. The NH4Cl solution has a higher Mg extraction capacity than KCl, but they present similar Ca and Al extraction ability. The NH4Cl solution extracted more K and Na than the Mehlich-1 solution. It is concluded that the ammonium chloride solution is a convenient alternative for the extraction of exchangeable Al, Ca, Mg, K, and Na from soils.

  19. Mullite-based coating on silicon carbide refractory obtained from PMSQ [poly(methylsilsesquioxane); Recobrimentos à base de mulita em refratário de carbeto de silício obtidos a partir de PMSQ [poli (metilsilsesquioxano)] e alumínio

    Silicon carbide (SiC) presents low thermal expansion, high strength and thermal conductivity. For this reason it is used as kiln furniture for materials sintering. On the other hand, SiC degrades at high temperature under aggressive atmosphere. The use of protective coatings can avoid the right exposition of SiC surface to the furnace atmosphere. Mullite can be a suitable material as protective coating because of its high corrosion resistance and thermal expansion coefficient matching that of SiC (4,7 x 10{sup -6}/°C e 5,3 x 10{sup -6}/°C, respectively). In the present work a mullite coating obtained from ceramic precursor polymer and aluminium powder was studied to be applied over SiC refractories. Compositions were prepared with 10, 20, 30 and 50% (vol.) of aluminium powder added to the polymer. They were used aluminium powders with different distributions sizes These compositions were heat treated at different thermal cycles to determine a suitable condition to obtain a high mullite content. The composition with 20% of the smaller particle size Al powder was selected and used to be applied as a suspension over SiC refractory. The applied suspension, after dried, crosslinked and heat treated, formed a mullite coating over SiC refractory. Cycles of thermal shock were performed in coated and uncoated SiC samples to compare each other. They were carried out 26 cycles of thermal shock, in the following conditions: 600°C/30 min. and air cooling to room temperature. After each thermal shock, samples were analysed by mean of optical and electron microscopy, elastic modulus was also determined. After thermal shock cycles the coating presented good adhesion and no significant damage were observed. (author)

    Full Text Available This work describes a hydrometallurgical route for processing spent commercial catalysts (CoMo and NiMo/Al2O3. Samples were preoxidized (500 ºC, 5 h in order to eliminate coke and other volatile species present. The calcined solid was dissolved in concentrated H2SO4 and water (1:1 vol/vol at 90 ºC; the insoluble matter was separated from the solution. Molybdenum was recovered by solvent extraction using tertiary amines at pH around 1.8. Cobalt (or nickel was separated by addition of aqueous ammonium oxalate at the above pH. Phosphorus was removed by passing the liquid through a strong anion exchange column. Aluminum was recovered by neutralizing the solution with NaOH. The route presented in this work generates less final aqueous wastes because it is not necessary to use alkaline medium during the metal recovery steps.

    Full Text Available Apesar das modernas e sofisticadas técnicas disponíveis, procedimentos de extração seletiva ainda são de considerável valor para a caracterização dos solos e para o entendimento dos processos pedogenéticos, sobretudo em ambientes e solos pouco estudados, como as restingas e os Espodossolos no Brasil. A aplicação dessas técnicas - a maioria rotineiramente utilizada para a caracterização de horizontes espódicos e Espodossolos - a um conjunto expressivo de horizontes e perfis em cronossequências é inédita para esses ambientes e possibilitou estabelecer comparações com aqueles intensivamente estudados sob clima temperado ou boreal. Apesar das reconhecidas limitações dos procedimentos analíticos de dissolução seletiva, os aqui utilizados foram relativamente efetivos, o que possiblitou discriminar horizontes, inferir componentes mineralógicos e discutir processos atuantes no conjunto de horizontes e de perfis analisados. Estes se situam nos municípios de Bertioga, Cananeia e Ilha Comprida (SP, onde foram descritos e amostrados 31 perfis representativos de solos sob vegetação de restinga. Entre os resultados encontrados, destacam-se: NaOH 0,5 mol L-1 em temperatura ambiente extraiu, em média, 22 a 30 % mais Al (Al n que os reagentes ditionito-citrato (Al d, oxalato (Al o e pirofosfato (Al p para todo o conjunto de amostras. Em alguns horizontes espódicos bem drenados (Bs, Bhs, Bh e Bsm, o pH e as interações entre as diferentes técnicas (Al n-Al o, Al o-Al p, Al p/Al o e Al p/Al d sugerem a formação e manutenção de compostos inorgânicos amorfos de Al em detrimento da total complexação do elemento à matéria orgânica iluviada. Esta última forma de Al predomina nos Espodossolos Hidromórficos.In spite of modern and sophisticated techniques, procedures of selective dissolution are still of considerable value for soil characterization and to the understanding of the pedogenetic process, especially environments and soils poorly studied, as the coastal plain regions and Spodosols of Brazil. The application of these techniques commonly used for characterization of spodic horizons and soil profiles for large amount horizons and soils studied in cronossequences are rare for those environments and become possible to establish comparisons with those intensively studied under boreal and temperate climatic. In spite of the recognized limitations of all selective dissolution techniques these used procedures were relatively selective and become possible (a the differentiation of the horizons, (b deduce mineralogical components of soil, and (c deduce pedogenetic process.

    Three coagulants viz. alum, FeCl/sub 3/ and Moringa oleifera seed extract were compared for treating municipal wastewater. The wastewater samples were collected from a drain near the Murree Road in Abbottabad city. The initial treatment depicted that alum was a suitable coagulant, while the other two caused color development and increased chemical oxygen demand in the effluent. Subsequently, wastewater samples were treatment with graded concentrations (4 32 mg.L/sup -1/ of alum in batch series, and shacked at 600-620 rpm for five minutes. The treated samples were analyzed for various water quality parameters to examine the effective coagulation and flocculation process in the wastewater. There was an increase in TDS and electrical conductivity with the increasing levels of alum above the optimized values (22 to 30 mg L/sup -1/). The process primary treatment strategy of wastewater treatment with alum is suitable for reducing the pollutants load in the sewer system. (author)

    Patikaraparpam, a Siddha formulation in prepared by trituration of potash alum with egg albumin followed by calcinatin. The three authentic laboratories made parpams as well as six commercial samples have been examined for their chemical composition. The analytical data that emerged from the analysis of the above samples showed that seven parpams contained only aluminium sulphate and they did respond to tests for potassium. An inspection of the crude drugs patikaram' available in the market established that potash alum and ammonia alum are indiscriminateldy taken for use, according to literature, only potash alum should be used in Indian system of medicine. Patikarapparapam is indicated in urinary inflammations and obstructions and is a reputed diuretic. Potassium salts are established diuretic. These studies show that the raw drugs sellers, the pharamaceutists or manufacturers of medicine and the physician as well should make sure that only potash alum is used in Indian medicine.

    PET, compared with SPECT, uses some similar techniques in image reconstruction, on the other hand, there are some difference on the techniques. A phantom experiment was conducted and the result was evaluated objectively through quantitative analysis in order to find ideal filter and cutoff frequency (Fc) for clinical application. The PET phantom have 6 solid inserts (cold) in the upper half and 6 hollow ones (hot) in the lower part. The middle insert is 1cm in diameter, the outer five have diameters of 1 to 3cm respectively. The phantom filled with 111 MBq 18 FDG and studied with segmentation acquisition. 25 set of images were reconstructed using HANN, HAMM, PARZEN, BUTTERWORTH, BUTTERWORTH2 filter and 0.1, 0.2, 0.3, 0.4, 0.5 Fe successively.A ROI of 4*4 pixels was drawn over middle 1 cm, outer 1cm, 3 cm cold column area and background area, the ratio between the ROI of cold column and background was calculated to evaluate the image contrast. A ROI of 15*15 pixels was drawn on the background area to get s.d as a judgement of image noise. A profile curve was drawn on the hollow column of middle 1 cm and outer 1 cm and their FWHM were compared with the real diameter to reflect linearity. With the same Fc, the contrast using HANN and HAMM filter was superior to other filter, The effect of the filter on image noise is listed in high to low order as HAMM, HANN, BUTTERWORTH, PARZEN and BUTTERWORTH2. The higher Fc, the higher image noise. The FWHM will increases as the Fc value decreases. With same Fc, the FWHM of different filter from small to big is HAMM, BUTTERWORTH, HANN, PARZEN, BUTTERWORTH2. The outer FWHM is larger than the middle one. For brain image, we suggest HAMM and HANN with Fc 0.3, 0.4 For image demanding lower resolution, we suggest BUTTERWORTH with Fc 0.4, 0.5, 2. For hot image, we can increase Fc to get high resolution. The FWHM value closed to the real value when HANN, HANN with Fc 0.3 and BUTTERWORTH with Fc 0.2. The 5% difference of FWHM between

    Glutamic acid decarboxylase (GAD) is a major target of the autoimmune response that occurs in type 1 diabetes mellitus. In animal models of autoimmunity, treatment with a target antigen can modulate aggressive autoimmunity. We aimed to assess whether immunisation with GAD formulated with aluminum hydroxide (GAD-alum) would preserve insulin production in recent-onset type 1 diabetes. Patients aged 3-45 years who had been diagnosed with type 1 diabetes for less than 100 days were enrolled from 15 sites in the USA and Canada, and randomly assigned to receive one of three treatments: three injections of 20 μg GAD-alum, two injections of 20 μg GAD-alum and one of alum, or 3 injections of alum. Injections were given subcutaneously at baseline, 4 weeks later, and 8 weeks after the second injection. The randomisation sequence was computer generated at the TrialNet coordinating centre. Patients and study personnel were masked to treatment assignment. The primary outcome was the baseline-adjusted geometric mean area under the curve (AUC) of serum C-peptide during the first 2 h of a 4-h mixed meal tolerance test at 1 year. Secondary outcomes included changes in glycated haemoglobin A(1c) (HbA(1c)) and insulin dose, and safety. Analysis included all randomised patients with known measurements. This trial is registered with ClinicalTrials.gov, number NCT00529399. 145 patients were enrolled and treated with GAD-alum (n=48), GAD-alum plus alum (n=49), or alum (n=48). At 1 year, the 2-h AUC of C-peptide, adjusted for age, sex, and baseline C-peptide value, was 0·412 nmol/L (95% CI 0·349-0·478) in the GAD-alum group, 0·382 nmol/L (0·322-0·446) in the GAD-alum plus alum group, and 0·413 nmol/L (0·351-0·477) in the alum group. The ratio of the population mean of the adjusted geometric mean 2-h AUC of C-peptide was 0·998 (95% CI 0·779-1·22; p=0·98) for GAD-alum versus alum, and 0·926 (0·720-1·13; p=0·50) for GAD-alum plus alum versus alum.

    Applications of aluminum sulfate (Al{sub 2}(SO{sub 4}){sub 3} {center_dot} 14H{sub 2}O), commonly referred to as alum, to poultry litter have been shown to decrease P runoff from lands fertilized with litter and to inhibit NH{sub 3} volatilization. The objectives of this study were to evaluate the effects of alum applications in commercial broiler houses on: (1) NH{sub 3} volatilization (in-house), (2) poultry production, (3) litter chemistry, and (4) P runoff following litter application. Two farms were used for this study: one had six poultry houses and the other had four. The litter in half of the houses at each farm was treated with alum; the other houses were controls. Alum was applied at a rate of 1,816 kg/house, which corresponded to 0.091 kg/bird. Each year the houses were cleaned in the spring and the litter was broadcast onto paired watersheds in tall fescue at each farm. Results from this study showed that alum applications lowered the litter pH, particularly during the first 3 to 4 wk of each growout. Reductions in litter pH resulted in less NH{sub 3} volatilization, which led to reductions in atmospheric NH{sub 3} in the alum-treated houses. Broilers grown on alum-treated litter were significantly heavier than controls (1.73 kg vs. 1.66 kg). Soluble reactive phosphorus (SRP) concentrations in runoff from pastures fertilized with alum-treated litter averaged 73% lower than that from normal litter throughout a 3-yr period. These results indicate that alum-treatment of poultry litter is a very effective best management practice that reduces nonpoint source pollution while it increases agricultural productivity.

    Microlenses are produced by irradiation of a layer of tot'hema and eosin sensitized gelatin (TESG) by using a laser beam (Nd:YAG 2nd harmonic; 532 nm). All the microlenses obtained are concave with a parabolic profile. After the production, the microlenses are chemically processed with various concentrations of alum. The following imaging properties of microlenses were calculated and analyzed: the root mean square (rms) wavefront aberration, the geometric encircled energy and the spot diagram. The microlenses with higher concentrations of alum in solution had a greater effective focal length and better image quality. The microlenses chemically processed with 10% alum solution had near-diffraction-limited performance.

    This study was conducted on the wastewater of PCSIR Laboratories complex Lahore. Both single as well as blended form was used in order to achieve maximum results and to reduce the cost. These experiments were conducted in Hudson Jars of one liter capacity using the coagulation technique for the removal of total suspended solids (TSS) and turbidity. The pH range was 6-8 and 4-10 for treatment. Four coagulants were used such as FeCl 3 , AlCl 3 . Alum and FeSO 4 , to remove the turbidity in single and blended form. Results of single coagulant are FeCl 3 from 39.7 to 11.51 NTU; AlCl 3 from 47.48 to 11.8 NTU. Alum 43 to 25.3NTU.FeSO 4 showed increasing trend in turbidity 53 to 120 NTU. The blended set of coagulants AlCl 3 +Alum turbidity from 45 to 18.55 NTU. The AlCl 3 and FeCl 3 showed almost similar results but after overnight settling results were excellent and alum showed also good results. The turbidity was removed from 54 to 27 NTU, 48 to 22 NTU, 44 to 17 NTU, and after overnight settling 33 to 4 NTU. The results of blended coagulants FeCl 3 +AlCl 3 after one, two and three hours settling were also studied and found best and blend AlCl3+Alum showed also similar trend and the blend of Alum+FeCl 3 after overnight settling was excellent. The same coagulants and its blended form were used for TSS removal and results are 278 to 7 mg/L, in blended form AlCl 3 +Alum show similar results but Alum + FeCl 3 showed excellent results. The TSS and turbidity removal was 87%, 97.5%. (author)

    Allergen-specific immunotherapy (SIT) is a clinically effective therapy for immunoglobulin (Ig)E-mediated allergic diseases. To reduce the risk of IgE-mediated side effects, chemically modified allergoids have been introduced. Furthermore, adsorbance of allergens to aluminium hydroxide (alum) is widely used to enhance the immune response. The mechanisms behind the adjuvant effect of alum are still not completely understood. In the present study we analysed the effects of alum-adsorbed allergens and allergoids on their immunogenicity in vitro and in vivo and their ability to activate basophils of allergic donors. Human monocyte derived dendritic cells (DC) were incubated with native Phleum pratense or Betula verrucosa allergen extract or formaldehyde-or glutaraldehyde-modified allergoids, adsorbed or unadsorbed to alum. After maturation, DC were co-cultivated with autologous CD4+ T cells. Allergenicity was tested by leukotriene and histamine release of human basophils. Finally, in-vivo immunogenicity was analysed by IgG production of immunized mice. T cell proliferation as well as interleukin (IL)-4, IL-13, IL-10 and interferon (IFN)-γ production were strongly decreased using glutaraldehyde-modified allergoids, but did not differ between alum-adsorbed allergens or allergoids and the corresponding unadsorbed preparations. Glutaraldehyde modification also led to a decreased leukotriene and histamine release compared to native allergens, being further decreased by adsorption to alum. In vivo, immunogenicity was reduced for allergoids which could be partly restored by adsorption to alum. Our results suggest that adsorption of native allergens or modified allergoids to alum had no consistent adjuvant effect but led to a reduced allergenicity in vitro, while we observed an adjuvant effect regarding IgG production in vivo.

    The distribution of uranium in kolm from Upper Cambriam alum shales has been studied using backscattered electron imagery, and found to be concentrated in discrete mineral phases. Authigenic minerals in kolm include pyrite, galena, and a cerium-bearing mineral referable to monazite. Uranium occurs within the monazite and generally shows a close relationship with phosphorus. Uranium bearing monazite has also been identified within the host alum shale.

    Full Text Available Coagulation - flocculation are basic chemical engineering method in the treatment of metal-bearing industrial wastewater because it removes colloidal particles, some soluble compounds and very fine solid suspensions initially present in the wastewater by destabilization and formation of flocs. This research was conducted to study the feasibility of using natural coagulant such as okra and mallow and chemical coagulant such as alum for removing Cu and increase the removal efficiency and reduce the turbidity of treated water. Fourier transform Infrared (FTIR was carried out for okra and mallow before and after coagulant to determine their type of functional groups. Carbonyl and hydroxyl functional groups on the surface of okra and mallow were the major groups responsible for coagulation process. By using alum (conventional coagulants, okra and mallow (as a primary coagulant or in combination with the other two primary coagulants and by the jar testing, the optimum pH-value and dose of the coagulants were determined. The results indicated that the optimal pH values were 6.7, 8 and 6 for alum, okra and mallow, respectively. Mathematical modeling show significant results (sig.<0.05 for the % Cu removal (dependent variable with respect to coagulant dose (independent variable for the okra as a primary coagulant, alum with okra and alum with mallow as binary coagulants and alum, okra and mallow as ternary coagulants .

  13. Aluminium per se and in the anti-acid drug sucralfate promotes sensitization via the oral route.

    Aluminium (ALUM) is used as experimental and clinical adjuvant for parenteral vaccine formulation. It is also contained in anti-acid drugs like sucralfate (SUC). These anti-acids have been shown to cause sensitization to food proteins via elevation of the gastric pH. The aim of this study was to assess the oral adjuvant properties of ALUM, alone or contained in SUC, in a BALB/c mouse model. Mice were fed SUC plus ovalbumin (OVA) and compared with groups where ALUM or proton pump inhibitors (PPI) were applied as adjuvants. The humoral and cellular immune responses were assessed on antigen-specific antibody and cytokine levels. The in vivo relevance was investigated in skin tests. The highest OVA-specific immunoglobulin G1 (IgG1) and IgE antibody levels were found in mice fed with OVA/SUC, followed by OVA/ALUM-treated animals, indicating a T helper 2 (Th2) shift in both groups. Antibody levels in other groups revealed lower (OVA/PPI-group) or baseline levels (control groups). Positive skin tests confirmed an allergic response in anti-acid or adjuvant-treated animals. Our data show for the first time that ALUM acts as a Th2-adjuvant via the oral route. This suggests that orally applied SUC leads to an enhanced risk for food allergy, not only by inhibiting peptic digestion but also by acting as a Th2-adjuvant by its ALUM content.

  12. Experimental additions of aluminum sulfate and ammonium nitrate to in situ mesocosms to reduce cyanobacterial biovolume and microcystin concentration

    Science.gov (United States)

    Harris, Ted D.; Wilhelm, Frank M.; Graham, Jennifer L.; Loftin, Keith A.

    2014-01-01

    Recent studies suggest that nitrogen additions to increase the total nitrogen:total phosphorus (TN:TP) ratio may reduce cyanobacterial biovolume and microcystin concentration in reservoirs. In systems where TP is >100 μg/L, however, nitrogen additions to increase the TN:TP ratio could cause ammonia, nitrate, or nitrite toxicity to terrestrial and aquatic organisms. Reducing phosphorus via aluminum sulfate (alum) may be needed prior to nitrogen additions aimed at increasing the TN:TP ratio. We experimentally tested this sequential management approach in large in situ mesocosms (70.7 m3) to examine effects on cyanobacteria and microcystin concentration. Because alum removes nutrients and most seston from the water column, alum treatment reduced both TN and TP, leaving post-treatment TN:TP ratios similar to pre-treatment ratios. Cyanobacterial biovolume was reduced after alum addition, but the percent composition (i.e., relative) cyanobacterial abundance remained unchanged. A single ammonium nitrate (nitrogen) addition increased the TN:TP ratio 7-fold. After the TN:TP ratio was >50 (by weight), cyanobacterial biovolume and abundance were reduced, and chrysophyte and cryptophyte biovolume and abundance increased compared to the alum treatment. Microcystin was not detectable until the TN:TP ratio was <50. Although both treatments reduced cyanobacteria, only the nitrogen treatment seemed to stimulate energy flow from primary producers to zooplankton, which suggests that combining alum and nitrogen treatments may be a viable in-lake management strategy to reduce cyanobacteria and possibly microcystin concentrations in high-phosphorus systems. Additional studies are needed to define best management practices before combined alum and nitrogen additions are implemented as a reservoir management strategy.

    The present study was aimed to investigate the performance of starch derived from cassava peel waste as primary coagulant and coagulant aid. Comparable study was also conducted using commercially used aluminium sulfate (alum) as primary coagulant. A series of Jar tests were performed using raw water from Sembrong Barat water treatment plant. It was observed that coagulation test using cassava peel starch (CPS) alone had unappreciable removing ability. However, it was found that combination of alum-CPS successfully achieve up to 90.48% of total suspended solid (TSS) removal under optimized working conditions (pH 9, 7.5mg/L : 100 mg/L of alum : CPS dosage, rapid mixing of 200 rpm for 1 minute; 100 rpm for 2 minutes, slow mixing of 25 rpm for 30 minutes and 30 minutes settling time). This remarks the reduction in alum dosage up to 50% compared to coagulation test using alum alone. Therefore this finding suggesting that CPS can be considered as potential source of sustainable and effective coagulant aid for water treatment especially in developing countries.

    Hibiscus rosa- sinensis is a biodegradable material that has remained untested for flocculating properties. The objective of this study is to examine the efficiency of coagulation-flocculation processes for the removal of color, iron (Fe3+), suspended solids, turbidity and ammonia nitrogen(NH3-N), from landfill leachate using 4,000 mg/L alum in conjunction with H. rosa- sinensis leaf extract (HBaqs). Hydroxyl (O-H) and (carboxyl) C=O functional groups along the HBaqs chain help to indulge flocculating efficiency of HBaqs via bridging. The experiments confirm the positive coagulation properties of HBaqs. The Fe3+ removal rate using 4,000 mg/L alum as sole coagulant was approximately 60 %, and increased to 100 % when 4,000 mg/L alum was mixed with 500 mg/L HBaqs. By mixing, 4,000 mg/L alum with 100-500 mg/L HBaqs, 72 % of SS was removed as compared with only 45 % reduction using 4,000 mg/L alum as sole coagulant.

    Powder of Onion shells as a source of natural flavonoid dye (Quercetin) and cotton fabrics were exposed to absorbed doses of 2, 4, 6, 8 and 10 kGy using Cs-137 gamma irradiator. Irradiated and un-irradiated dye powder was used for extraction of quercetin as well as antibacterial, hemolytic and antioxidant activities were also determined to observe the effect of radiation. Furthermore, color strength and colourfastness of irradiated fabrics were improved by using pre and post-mordants such as alum and iron. It is found that 4 kGy is the optimal absorbed dose for extraction of natural quercetin extracted from onion shells while maximum color strength and acceptable fastness properties are obtained on dyeing of irradiated fabric at 60 °C keeping M:L of 1:30 using 10% alum as pre-mordant and 6% alum as post-mordant. Gamma irradiation has not only improved the color strength of the dye using irradiated cotton but also that of colourfastness properties. - Highlights: • The optimal absorbed dose obtained for surface modification of cotton (RC) is 4 kGy. • The optimal absorbed dose for extraction of colorant from onion shell powder (RP) is 4 kGy. • Optimum dying conditions: 60 °C, 1 30 as M:L. • Optimum pre-mordant 10% alum and 6% alum as post-mordant. • At these optimum conditions: color strength and fastness properties are improved

    This paper explores the use of electrocoagulation to remove boron from waste effluent in comparison with alum coagulation. In treating model test wastes, greater boron removals were achieved with electrocoagulation at low doses than conventional alum coagulation when reaction was undertaken for the same conditions (pH 8.5, and initial boron concentration was 500 mg/L). Al electrocoagulation can achieve good boron removal performance (68.3%) at a dose of 2.1 (as molar ratio of Al:B, and for current density of 62.1 A/m2), while alum coagulation can only achieve the maximum boron removal of 56% at a dose of 2.4. Also, Al electrocoagulation can remove 15-20% more boron than alum coagulation for the same dose compared in the treatment of both model test wastes and industry effluent. The estimation of running costs shows that to achieve 75% boron removal from industry waste effluent, i.e. removing 150 g of boron from 1 m3 of effluent, electrocoagulation was 6.2 times cheaper than alum coagulation. The economic advantage of electrocoagulation in the treatment of boron-containing waste effluent is thus significant.

    This proposed method is a promising way, which can be implemented in pulp and paper industries by effective removal of the color and chemical oxygen demand (COD) and the resulting treated water may surely reuse to the other streams. Fourier Transformer Infra Red spectra confirmed the presence of the respective functional groups in the removed pollutants from the wastewater. The efficiency of Non-ferric Alum (NF Alum) and cationic polyacrylamide (C-PAM) with and without power boiler fly ash was also studied. The reduction efficiency of color and chemical oxygen demand (COD) is evaluated at the optimum dosage of NF Alum, fly ash, and C-PAM. At the optimized pH attained from these coagulants using to treat the wastewater, the flocs formation/settling and the pollutant removal efficiency are encouraging and the resulting color of the wastewater is to 40 PtCo units from 330 PtCo units and COD to 66 mg/L from 218 mg/L. While using NF Alum alone with C-PAM for the treatment of wastewater, the highest reduction efficiency of COD is 97 mg/L from 218 mg/L and the color is 60 from 330 PtCo units at pH 4.8 was noted. From these observations, NF Alum and power boiler fly ash with C-PAM can effectively remove the pollutants from the pulp and paper mill wastewater and the water can be reused for other streams.

    Full Text Available As a tanning material alum salt has similar properties of the basic chromium sulphate. It is, therefore, the purpose of this research is to exchange chromium tannage with alum tannage in pretanning for the vegetable tanned lining leather. In doing such a way the chromium pollution may be eliminated, whereas the alum pretanned lining leather output must be fulfill the physical and chemical requirements as that one of the chrome pretanned. In pretanning the use of alum tannage varied from 2,5%, 3,0%, 3,5% and 4,0%. Afterwards the subsequent process was vegetable tanning using 30% of mimosa powder. The lining leather output from the research was physical and chemical tested. The practical meaning of this research is that for pretanning the vegetable tanned lining leather it is possible to use 2,5% alum salt. The values of the physical and chemical test obtained are that the degree of tannage is 94,54, tensile strength is 174,24 kg/cm2, and strength is 22%. Water absorption for 2 hours is 133,01% and for 24 hours is 134,48%. Whereas the flexural endurance is unbreak condition.

    The growth rate and size of floc formation is of great importance in water treatment especially in coagulation process. The floc formation kinetics and the coagulation efficiency of synthetic water were investigated by using an on-line continuous optical photometric dispersion analyze and the analysis of water quality. Experimental conditions such as alum dosage, pH value for coagulation, stirring intensity and initial turbidity were extensively examined. The photometric dispersion analyze results showed that coagulation of kaolin suspensions with two coagulants (alum and polyaluminium chloride) could be taken as a two-phase process: slow and rapid growth periods. Operating conditions with higher coagulant doses, appropriate pH and average shear rate might be particularly advantageous. The rate of overall floc growth was mainly determined by a combination of hydraulic and water quality conditions such as pH and turbidity. The measurement of zeta potential indicates that polyaluminium chloride exhibited higher charge-neutralizing ability than alum and achieved lower turbidities than alum for equivalent Al dosages. Under the same operating conditions, the alum showed a higher grow rate, but with smaller floc size.

    Full Text Available Experiments are done for different combinations of Fe+2 and Mn+2 concentrations. The obtained results show that Potassium Permanganate (PP gives good results in iron and manganese removal. By using PP dose near to half of the theoretically required one, it can remove up to 100 % and 90 % of iron and manganese, respectively over different tested concentrations at pH=7.0. Increasing rate of filtration influences the Mn+2 removal process obviously. Sedimentation is required when combined concentrations of iron and manganese are greater than 5.0 ppm to reduce filter rapid clogging. Using conventional treatment with adding alum, flocculation, sedimentation and filtration can remove up to 97% and 18% of iron and manganese, respectively. Using PP in addition to alum enhances manganese removal but decreases iron removal. However, using alum with increasing pH to 10 leads to 100 % and 95 % of Fe+2 and Mn+2 removal and increases filter working period.

    Full Text Available Research literature on the extraction of alum, the mineral salt basic to the economy of Christian Europe, entirely passes over the Iberian deposits in production between the fall of Constantinople and the commencement of the Papal operation at Tolfa in 1463. The sites of these are here identified, with an indication that their mineralogical formation is not that of the classic volcanic strata of Tuscany and Mazarrón. The much repeated theory on the way alum-bearing rock was located is shown to be suspect, and the pre-Mazarrón history of Spanish alum is given its context in the turbulent politics of the mid-century dynastic confrontations.

    When adding sufficient chlorine to achieve breakpoint chlorination to source water containing high concentration of ammonia during drinking water treatment, high concentrations of disinfection by-products (DBPs) may form. If N-nitrosamine precursors are present, highly toxic N-nitrosamines, primarily N-nitrosodimethylamine (NDMA), may also form. Removing their precursors before disinfection should be a more effective way to minimize these DBPs formation. In this study, zeolites and activated carbon were examined for ammonia and N-nitrosamine precursor removal when incorporated into drinking water treatment processes. The test results indicate that Mordenite zeolite can remove ammonia and five of seven N-nitrosamine precursors efficiently by single step adsorption test. The practical applicability was evaluated by simulation of typical drinking water treatment processes using six-gang stirring system. The Mordenite zeolite was applied at the steps of lime softening, alum coagulation, and alum coagulation with powdered activated carbon (PAC) sorption. While the lime softening process resulted in poor zeolite performance, alum coagulation did not impact ammonia and N-nitrosamine precursor removal. During alum coagulation, more than 67% ammonia and 70%-100% N-nitrosamine precursors were removed by Mordenite zeolite (except 3-(dimethylaminomethyl)indole (DMAI) and 4-dimethylaminoantipyrine (DMAP)). PAC effectively removed DMAI and DMAP when added during alum coagulation. A combination of the zeolite and PAC selected efficiently removed ammonia and all tested seven N-nitrosamine precursors (dimethylamine (DMA), ethylmethylamine (EMA), diethylamine (DEA), dipropylamine (DPA), trimethylamine (TMA), DMAP, and DMAI) during the alum coagulation process.

    Pritchard, M.; Craven, T.; Mkandawire, T.; Edmondson, A. S.; O'Neill, J. G.

    A research project was commissioned to investigate the performance of Moringa oleifera compared with that of aluminium sulphate (Al 2(SO 4) 3) and ferric sulphate (Fe 2(SO 4) 3), termed alum and ferric respectively. A series of jar tests was undertaken using model water, different raw water sources and hybrid water containing a mixture of both of these types of water. The model water consisted of deionised water spiked with Escherichia coli (E. coli) at 10 4 per 100 ml and turbidity (146 NTU) artificially created by kaolin. Results showed that M. oleifera removed 84% turbidity and 88% E. coli, whereas alum removed greater than 99% turbidity and E. coli. Low turbidity river water (<5 NTU), with an E. coli count of 605 colony forming units (cfu)/100 ml was treated with M. oleifera and ferric. Results showed an 82% and 94% reduction in E. coli for M. oleifera and ferric respectively. Tests on turbid river water of 45 NTU, with an E. coli count of 2650 cfu/100 ml, showed a removal of turbidity of 76% and E. coli reduction of 93% with M. oleifera. The equivalent reductions for alum were 91% and 98% respectively. Highly coloured reservoir water was also spiked with E. coli (10 4 cfu/100 ml) and turbidity (160 NTU) artificially created by kaolin; termed hybrid water. Under these conditions M. oleifera removed 83% colour, 97% turbidity and reduced E. coli by 66%. Corresponding removal values for alum were 88% colour, 99% turbidity and 89% E. coli, and for ferric were 93% colour, 98% turbidity and 86% E. coli. Tests on model water, using a secondary treatment stage sand filter showed maximum turbidity removal of 97% and maximum E. coli reduction of 98% using M. oleifera, compared with 100% turbidity and 97% E. coli for alum. Although not as effective as alum or ferric, M. oleifera showed sufficient removal capability to encourage its use for treatment of turbid waters in developing countries.

    The identification of effective adjuvants is critical for tumor vaccine development. Towards this end, we examined whether the immunogenicity of a melanoma vaccine could be potentiated by DETOX, an adjuvant consisting of monophosphoryl lipid A (MPL) and purified mycobacterial cell-wall skeleton (CWS). Nineteen patients with resected stage III melanoma were immunized with a polyvalent melanoma antigen vaccine (40 micrograms) admixed with DETOX, q3 wks x 4. Seven patients received vaccine + low-dose DETOX (10 micrograms MPL + 100 micrograms CWS) and 12 received vaccine + high-dose DETOX (20 micrograms MPL + 200 micrograms CWS). A non-randomized control group of 35 patients was treated similarly with 40 micrograms vaccine + alum. One week after the fourth vaccine immunization, melanoma antibodies were increased over baseline in 7/7 (100%) patients treated with vaccine + low-dose DETOX, 8/12 (67%) patients treated with vaccine + high-dose DETOX, and in 4/19 (21%) of vaccine + alum patients. For the entire DETOX group, the antibody response rate was 15/19 (79%) compared 4/19 (21%) in the alum group (p or = 15 mm increase in DTH response over baseline) was induced in 50% of the entire DETOX group versus in 47% of the alum group. Median disease-free (DF) survival for the entire DETOX group was 17.8 months compared with 32.1 months in the alum group (p DETOX markedly potentiated antibody but had little effect on DTH responses to melanoma vaccine immunization. It did not appear to improve disease-free survival in comparison to alum in this non-randomized study.

    The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes. We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.3 ng per milliliter (0.1 nmol per liter), and detectable serum GAD65 autoantibodies. Within 3 months after diagnosis, patients were randomly assigned to receive one of three study treatments: four doses of GAD-alum, two doses of GAD-alum followed by two doses of placebo, or four doses of placebo. The primary outcome was the change in the stimulated serum C-peptide level (after a mixed-meal tolerance test) between the baseline visit and the 15-month visit. Secondary outcomes included the glycated hemoglobin level, mean daily insulin dose, rate of hypoglycemia, and fasting and maximum stimulated C-peptide levels. The stimulated C-peptide level declined to a similar degree in all study groups, and the primary outcome at 15 months did not differ significantly between the combined active-drug groups and the placebo group (P=0.10). The use of GAD-alum as compared with placebo did not affect the insulin dose, glycated hemoglobin level, or hypoglycemia rate. Adverse events were infrequent and mild in the three groups, with no significant differences. Treatment with GAD-alum did not significantly reduce the loss of stimulated C peptide or improve clinical outcomes over a 15-month period.

    Full Text Available Advances in nanotechnology and nanomaterials have facilitated the development of silicon dioxide, or Silica, particles as a promising immunological adjuvant for the generation of novel prophylactic and therapeutic vaccines. In the present study, we have compared the adjuvanting potential of commercially available Silica nanoparticles (initial particles size of 10-20 nm with that of aluminium hydroxide, or Alum, as well as that of complete and incomplete Freund's adjuvants for the immunisation of BALB/c mice with virus-like particles (VLPs formed by recombinant full-length Hepatitis B virus core (HBc protein. The induction of B-cell and T-cell responses was studied after immunisation. Silica nanoparticles were able to adsorb maximally 40% of the added HBc, whereas the adsorption capacity of Alum exceeded 90% at the same VLPs/adjuvant ratio. Both Silica and Alum formed large complexes with HBc VLPs that sedimented rapidly after formulation, as detected by dynamic light scattering, spectrophotometry, and electron microscopy. Both Silica and Alum augmented the humoral response against HBc VLPs to the high anti-HBc level in the case of intraperitoneal immunisation, whereas in subcutaneous immunisation, the Silica-adjuvanted anti-HBc level even exceeded the level adjuvanted by Alum. The adjuvanting of HBc VLPs by Silica resulted in the same typical IgG2a/IgG1 ratios as in the case of the adjuvanting by Alum. The combination of Silica with monophosphoryl lipid A (MPL led to the same enhancement of the HBc-specific T-cell induction as in the case of the Alum and MPL combination. These findings demonstrate that Silica is not a weaker putative adjuvant than Alum for induction of B-cell and T-cell responses against recombinant HBc VLPs. This finding may have an essential impact on the development of the set of Silica-adjuvanted vaccines based on a long list of HBc-derived virus-like particles as the biological component.

    New alternatives are necessary if the environmental impact linked to intensive poultry production is to be reduced, and different litter handling methods should be explored. Among these, acidifying amendments added to poultry litters has been suggested as a management practice to help reduce the potential environmental effect involved in multiple flock cycles. There have been several studies on the use of aluminum sulfate (alum) and its benefits, but almost no data are available under farm conditions in Europe. An experiment with Ross 308 broilers from 1 to 42 days of age was conducted to evaluate the effect of alum on litter composition, the solubility of some mineral elements and NH3 emission during a single flock-rearing period in commercial houses located in southeast Spain. Broilers were placed on clean wood shavings in four commercial houses, containing 20 000 broilers each. Before filling, alum was applied at a rate of 0.25 kg/m2 to the wood shavings of two poultry houses, whereas the remaining two were used as control. Litter from each poultry house was sampled every 3 to 5 days. Ammonia emissions from the poultry houses were monitored from 37 to 42 days of age. In comparison with the control group, alum treatment significantly reduced the pH level of the litter (P litter showed, on average, a higher electrical conductivity than the control litter (5.52 v. 3.63 dS/m). The dry matter (DM) and total N and P contents did not show differences between the treatments (P > 0.05). Regarding the NH4 +-N content, alum-treated litter showed a higher value than the untreated litter, with an average difference of 0.16 ± 0.07% (on a DM basis). On average, alum-treated litter had lower water-soluble P, Zn and Cu contents than the untreated litter. Alum noticeably reduced the in-house ammonia concentration (P litter, with a corresponding positive effect on the building environment and poultry health. For these reasons, litter amendment with alum could be recommended as a

    In the Niayes area, located in the west of Senegal, only one tsetse species, Glossina palpalis gambiensis Vanderplank (Diptera: Glossinidae) was present. The Government of Senegal initiated and implemented an elimination programme in this area that included a sterile insect technique (SIT) component. The G. p. gambiensis strain (BKF) mass-reared at the Centre International de Recherche-Développement sur l'Elevage en zone Subhumide (CIRDES) in Burkina Faso was used for the SIT component. Studies conducted in 2011 in four localities in the Niayes area (Pout, Sébikotane, Diacksao Peul and the Parc de Hann) showed that the BKF strain demonstrated inferior survival in the ecosystem of the Parc de Hann, a forested area in the city centre of the capital Dakar. Therefore, G. p. gambiensis flies from the Niayes area (SEN strain) were colonized. Here we compared the competitiveness and survival of the two strains (BKF and SEN) in the Parc de Hann. Released sterile males of the SEN colony showed a daily mortality rate of 0.08 (SD 0.08) as compared with 0.14 (SD 0.08) for the BKF flies but the difference was not significant (p-value = 0.14). However, the competitiveness of the SEN males was lower (0.14 (SD 0.10)) as compared with that of the BKF males (0.76 (SD 0.11)) (p-value competitiveness of the BKF males is deemed more important for the SIT component, as their shorter survival rates can be easily compensated for by more frequent fly releases.

    In 1922 Hanns Walter Kornblum produced a long and comprehensive educational film on Albert Einstein’s theory of relativity that made extensive use of trick shots. His film was considered to be a milestone in the history of film and also in the popularization of science. Although the original film has been lost, I have reconstructed its content and its reception by members of the German film industry and cultural sector, laymen, scientists and academics, and politically motivated opponents based upon the large collection of newspaper clippings that was assembled by the antirelativist physicist Ernst Gehrcke.

  7. A comparative analysis of the effect of gaseous fission products release on the thermal behaviour of oxide fuel rods

    1992-01-01

    Four different models of gaseous fission product release are compared in order to assess the relative effect of thermal characteristics of the fuel rods. The results show that the use of Weisman and EPRI models at a high burnup (over 50000 MW.d/tU) leads to almost the same figures of maximum fuel temperature and gas gap thermal conductivity. The use of Beyer-Hann (Betelle) and Pazdera-Valach (Rzez) models leads to under prediction of the fuel element thermal characteristics. A conclusion has been made that the Weisman model is the most suitable for the WWER-type fuel elements behaviour prediction. 10 refs., 7 figs

Kim starts with vibrations and waves, demonstrating how vibration can be envisaged as a kind of wave, mathematically and physically. One-dimensional waves are used to convey the fundamental concepts. Readers can then understand wave propagation in terms of characteristic and driving point impedance. The essential measures for acoustic waves, such as dB scale, octave scale, acoustic pressure, energy, and intensity, are explained. These measures are

  15. Inflammation triggers emergency granulopoiesis through a density-dependent feedback mechanism.

    Directory of Open Access Journals (Sweden)

    Derek W Cain

    Full Text Available Normally, neutrophil pools are maintained by homeostatic mechanisms that require the transcription factor C/EBPα. Inflammation, however, induces neutrophilia through a distinct pathway of "emergency" granulopoiesis that is dependent on C/EBPβ. Here, we show in mice that alum triggers emergency granulopoiesis through the IL-1RI-dependent induction of G-CSF. G-CSF/G-CSF-R neutralization impairs proliferative responses of hematopoietic stem and progenitor cells (HSPC to alum, but also abrogates the acute mobilization of BM neutrophils, raising the possibility that HSPC responses to inflammation are an indirect result of the exhaustion of BM neutrophil stores. The induction of neutropenia, via depletion with Gr-1 mAb or myeloid-specific ablation of Mcl-1, elicits G-CSF via an IL-1RI-independent pathway, stimulating granulopoietic responses indistinguishable from those induced by adjuvant. Notably, C/EBPβ, thought to be necessary for enhanced generative capacity of BM, is dispensable for increased proliferation of HSPC to alum or neutropenia, but plays a role in terminal neutrophil differentiation during granulopoietic recovery. We conclude that alum elicits a transient increase in G-CSF production via IL-1RI for the mobilization of BM neutrophils, but density-dependent feedback sustains G-CSF for accelerated granulopoiesis.

    Energy Technology Data Exchange (ETDEWEB)

    Chaudhuri, M.; Sattar, S.A.

    1986-01-01

    Using poliovirus type 1 (Sabin) and dechlorinated tap water, several coal-based sorbents were tested for their capacity to remove viruses from water. The sorbents included bituminous coal from Giridih, India, pretreated/impregnated with either alum, ferric hydroxide, lime or manganese dioxide. Filtrasorb-400, commercially available active carbon, was used as a reference. In batch tests, with input virus concentration of 2.34-2.83x10/sup 6/ PFU/1 and sorbent concentration of 10 g/l, alum pretreated coal removed about 96% of the virus when pH of the water was between 6.3 and 8.9. Virus sorption was rapid and a plateau was reached in 30 min. Compared with the active carbon, alum pretreated coal exhibited greater sorption energy and about one log higher limiting poliovirus sorption capacity. Downflow column study indicated the potential of alum pretreated coal as a filter media for removing enteric viruses from water. A previous study showed this sorbent to be capable of removing enteric bacteria as well. Water filters prepared from such low-cost material may prove useful for domestic use in rural areas of India and other developing countries. 19 refs.

  1. Coagulation and electrocoagulation for co-treatment of stabilized landfill leachate and municipal wastewater

    2018-04-01

    Full Text Available Landfill leachate and municipal wastewater at various ratios (1:20, 1:10, 1:7 and 1:5 were subjected to coagulation and electrocoagulation (EC. Alum was used in conventional coagulation at pH 6 and aluminum plate as electrode was used in EC at a current density of 386 A/m2 with 5 cm inter electrode spacing. Treatment efficiency was assessed from removal of chemical oxygen demand (COD, total suspended solids (TSS, turbidity, ammonia, nitrate and phosphate. At 1:5 ratio of landfill leachate to municipal wastewater, highest COD removal was with 3.8 g/L alum whereas highest turbidity removal was with 3.3 g/L alum during coagulation. EC exhibited almost similar removal efficiency for all the parameters at different ratios tested except for COD which was considerably higher at 1:20 ratio. Aluminum consumption from electrode was 0.7 g/L following EC as compared to 3.8 g/L alum used in coagulation. The amount of sludge produced was found to be higher with EC as compared to coagulation which could be due to the fact that the electrochemical method was performed for a longer duration than conventional coagulation. For minimal sludge generation, EC reaction time should be ∼30 min. Further studies with EC process on costing and sludge generation will help to advance the technology for wastewater treatment.

    Full Text Available The feasibility of using combination of effective microorganism (EM1 and conventional chemical conditioner was evaluated in this study to assess and discern the dewatering properties of the secondary sludge that produced from wastewater treatment plant of the medical assembly in Mosul city. Conventional coagulants such as lime, Alum, and ferrous sulfate, six doses for each coagulant type i.e5- 30(10 - 60 (and (25 -150mg/l(  respectively, were used in the sludge conditioning processes for enhancement of the sludge dewatering capacity. The characteristics of conditioned sludge, such as specific resistance of filtration (SRF (were determined at each dose.Experimental results indicated that effective microorganism seeds have a passive effect on SRF value which was about   % 71.4(and (%75(in lime and ferrous sulfate respectively.While in Alum conditioning process a significant effect on SRF reduction was accomplished which was about %-47.9( and (- %32.8( for effective microorganism and Alum dose increments respectively. The best Alum dosage, for minimum SRF 0.98348×10 12 m /kg, was 60 mg/l at 1 % of effective microorganism.
