Simple Chemical Method for the Determination of Carbon Dioxide in Air

The determination of carbon dioxide in air was always an important practical problem. It became particularly important in recent decades because of the studies of the greenhouse effect Because of difficulties in the direct detection of the equivalence point for the interaction of low concentrations of CO 2 with reagents, the two-step titration method is most frequently used among chemical methods for the determination of CO 2 . Within this method, first an aliquot portion of a solution of barium hydroxide of known concentration is partially neutralized with carbon dioxide contained in a known volume of air, and next residual Ba(OH) 2 is titrated with a reference solution of acid Known instrumental methods In this work, we propose a chemical method for the determination of CO 2 in air, which differs from the method mentioned above by a lower cost and simple implementation, being highly competitive with them in accuracy. The method is based on the detection of the equivalence point in the neutralization of an aqueous solution of Ba(OH) 2 by CO 2 contained in air by measuring the electrical conductance of the solution. The accurate detection of the equivalence point in this case is caused by the fact that CO 2 interacts with Ba(OH) 2 in two reactions proceeding successively [9]: Ç ‡ +2 + 2éç -+ ëé 2 = Ç ‡ëé 3 ↓ + ç 2 é, Ç ‡ëé 3 + ëé 2 + ç 2 é = Ç ‡ 2+ + . From the equations of the reactions, it follows that, at the first step of CO 2 absorption, barium and hydroxyl ions are removed from the solution because of the formation of a barium carbonate precipitate, which leads to a decrease in the electrical conductance of the solu- Abstract -A method was proposed for the direct determination of carbon dioxide in air using a sorption tube specially constructed for this purpose. The method is based on measuring the volume of air consumed for the neutralization of a known amount of barium oxide hydrate in the tube by carbon dioxide contained in air. The equivalence point is detected by the minimum electrical conductance of the barium hydroxide solution. To verify the accuracy of the method, a technique based on the use of a calibration mixture of air with the CO 2 concentration varying by the inverse exponential law was developed. The method is suitable for the determination of CO 2 in air in a wide concentration range and for the verification and calibration of indirect methods for the determination of CO 2 . With an insignificant decrease in accuracy, the equivalence point can be detected by the change in the color of phenolphthalein. This significantly simplifies the method and allows its wide use in practice, e.g., in laboratory works in environmental science or for demonstration purposes in educational organizations

Development of Intelligent Interface to Input and Edit Meteorological Data

The paper presents the method of development of user interface for the hydrometeorological data acquisition system. This research includes some basic principles of creating hydrometeorological messages according to code KN-01 SYNOP. This code allows creating messages as a set of code groups. Every group keeps values of definite meteorological properties. The result of studies was implemented in creating of the user interface for the software that allows working with hydrometeorological data. The KN-01 code defines the class hierarchy of this software. The studies have shown that this method of software development is especially effective for visualization of the meteorological telegrams on devices with small display

Underestimated risks of recurrent long-range ash dispersal from northern Pacific Arc volcanoes

Widespread ash dispersal poses a significant natural hazard to society, particularly in relation to disruption to aviation. Assessing the extent of the threat of far-travelled ash clouds on flight paths is substantially hindered by an incomplete volcanic history and an underestimation of the potential reach of distant eruptive centres. The risk of extensive ash clouds to aviation is thus poorly quantified. New evidence is presented of explosive Late Pleistocene eruptions in the Pacific Arc, currently undocumented in the proximal geological record, which dispersed ash up to 8000?km from source. Twelve microscopic ash deposits or cryptotephra, invisible to the naked eye, discovered within Greenland ice-cores, and ranging in age between 11.1 and 83.7 ka b2k, are compositionally matched to northern Pacific Arc sources including Japan, Kamchatka, Cascades and Alaska. Only two cryptotephra deposits are correlated to known high-magnitude eruptions (Towada-H, Japan, ca 15 ka BP and Mount St Helens Set M, ca 28 ka BP). For the remaining 10 deposits, there is no evidence of age- and compositionally-equivalent eruptive events in regional volcanic stratigraphies. This highlights the inherent problem of under-reporting eruptions and the dangers of underestimating the long-term risk of widespread ash dispersal for trans-Pacific and trans-Atlantic flight route

New opportunities of increase of complex therapy productivity with the symptomatic locally-caused epilepsy with the resistant current

Efficiency of Phenotropili preparation was studied in jugulating of asthenia among patients with resistant symptomatic localization related epilepsy. Some patients (62 persons) against the basic antiepileptic therapies put on Phenotropili in a dose 100 mg (18 persons) and 200 mg (22 persons) a day in a continuous course, during 3 months. The assessment of this therapy influence was conducted in relation to the group accepting a placebo (22 persons). It was specified an authentic decrease of all types of asthenia, and efficiency of a preparation in a dose of 100 mg a day practically didn't concede efficiency of 200 mg a day.Изучалась эффективность препарата Фенотропил® при купировании астении у пациентов с резистентной симптоматической локально-обусловленной эпилепсией.

Unadapted and adapted to starvation Acholeplasma laidlawii cells induce different responses of Oryza sativa, as determined by proteome analysis

For the first time, we studied the phytopathogenicity toward Oryza sativa L. of unadapted and adapted to unfavorable environment (starvation) cells of Acholeplasma laidlawii PG8 - ubiquitous mycoplasma found in the soil, waste waters, tissues of the highest eukaryotes and being the basic contaminant of cell cultures and a causative agent of phytomycoplasmoses. The features of morphology, ultrastructural organization and proteomes of unadapted and adapted cells of the mycoplasma and infected plants were presented. Using 2D-DIGE and MS, 43 proteins of O. sativa L. that were differentially expressed in the leaves of plants cultivated in media with A. laidlawii PG8 were identified. The qualitative and quantitative responses of the plant proteome toward adapted and unadapted mycoplasma cells differed. That may be explained by differences in the virulence of the corresponding bacterial cells. Using 2D-DIGE and MS, 82 proteins that were differentially expressed in adapted and unadapted mycoplasma cells were detected. In adapted cells of the mycoplasma, in comparison with unadapted ones, a significant increase in the expression of PNPase - a global regulator of virulence in phytopathogenic bacteria occurred; there was also decreased expression of 40 proteins including 14 involved in bacterial virulence and the expression of 31 proteins including 5 involved in virulence was not detected. We propose that differences in the phytopathogenicity of adapted and unadapted A. laidlawii PG8 cells may be related to features of their proteomes and membrane vesicles. © 2011 Elsevier B.V
