where pM/G/1(z) is the departure time queue length probability generating function for a standard M/G/1 queue (where D = 0). The so-called decomposition structure of (1) would have been valid if service times of νD customers (who arrived during an idle period) were i.i. d. random variables. Suppose the server has just finished serving all νD customers. The probability generating function for the number of customers in the system is then given byBνD(λ−λz). If this number is zero (with a probability BνD(λ)), the next idle period begins. Otherwise, the busy period continues. At this point in time, however, service times of those already in the system and of those yet to arrive until the end of the busy period are all i.i. d. random variables. Thus, from this point on, the departure process is identical to that of the M/G/1 queue with generalized vacations such that the probability generating function for the number of arrivals during an idle period is given by

Growth Stages of the Grapevine: Phenological growth stages of the grapevine (Vitis vinifera L. ssp. vinifera)—Codes and descriptions according to the extended BBCH scale†

The detailed crop specific descriptions of the phenological growth stages of grapevine are supplementary to the general BBCH-scale. It will be instrumental in standardising the national and international experimentation in viticulture. The phenological development of the grapevine is divided into growth phases (principal growth stages 0–9) and each growth phase is subdivided into growth steps (secondary growth stages 0–9). A two-digit code is attached to each growth stage. The description and coding of the phenological growth stages covers the period between dormancy and leaf fall.

The data mining algorithm is used to analyze the crime data.
Arsenic accidental soil contamination near Manfredonia. A case history

Abstract An aerosol mixture containing approximately 12 t of K3AsO3 and H3AsO3 escaped from the NH3 washing column of the ANIC chemical factory near Manfredonia, Southern Italy, in September 26th, 1976, and contaminated about 15 km2 of the surrounding area, largely cultivated. Among the various measures established to face the aceident, this report describes particularly the soil decontamination strategy. The latter, based on an oxidation‐precipitation treatment using CaOCl2 to oxidize As(III) to As(V) and FeSO4 to form highly insoluble arsenate, integrated the sequestering character of the soil, so that complete inertization of As throughout the accident area was readily attained.
Evolution and Control of Complex Curved Form in Simple Inorganic Precipitation Systems

Crystal architectures delimited by sinuous boundaries and exhibiting complex hierarchical structures are a common product of natural biomineralization. However, related forms can also be generated in purely inorganic environments, as exemplified by the existence of so-called “silica-carbonate biomorphs”. These peculiar objects form upon coprecipitation of barium carbonate with silica and self-assemble into aggregates of highly oriented, uniform nanocrystals, displaying intricate noncrystallographic morphologies such as flat sheets and helicoidal filaments. While the driving force steering ordered mineralization on the nanoscale has recently been identified, the factors governing the development of curved forms on global scales are still inadequately understood. In the present work, we have investigated the circumstances that lead to the expression of smooth curvature in these systems and propose a scenario that may explain the observed morphologies. Detailed studies of the growth behavior show that morpho.
Permeability of illite-bearing shale: 2. Influence of fluid chemistry on flow and functionally connected pores

[1] Bedding-parallel permeability of illite-rich shale of the Wilcox formation has been investigated using distilled water and 1 M solutions of NaCl, KCl, and CaCl2 as pore fluids. Despite low modal concentrations of swelling clays, specimens expand upon fluid saturation and permeabilities depend on fluid composition. Permeabilities to flow of 1 M CaCl2 are 3–5 times greater than values measured for the other pore fluids, suggesting sensitivity to exchange of divalent cations for monovalent cations at clay mineral surfaces. Permeabilities of individual samples exhibit nonrecoverable changes with sequential changes in composition of incoming fluid. Permeabilities k at varying effective pressure Pe fit a cubic law k = k0 [1 � (Pe/P1) m ] 3 , where m and P1 are independent of fluid composition, and k0 is greater for transport of 1 M CaCl2 than that for transport of the other pore fluids. Assuming that fluid conduits have crack-like dimensions, the lack of sensitivity of m and P1 to fluid composition suggests that surface roughness and asperity stiffness of conduits are unaffected by cation exchange, while changes in k0 reflect changes in the clay-fluid interfaces of the connected pore space.

Effect of In and Sb Vacancies on Temperature Dependence of InSb Lattice Parameter at High Temperatures

The temperature dependence of the thermal expansion coefficient for InSb has been determined in the range 25–515 °C by precision measurements of the lattice parameter of InSb single crystals. It is shown that beginning from 460 °C the temperature dependence of the lattice parameter for InSb single crystals grown from melts of different compositions is essentially affected by vacancies in the indium and antimony sublattices. The vacancy concentration and possible deviation of InSb from the stoichiometric composition are estimated from a relative decrease in the lattice parameter. [Russian Text Ignored. ]
Experimental Characterization of Thin-film Ceria Solid Oxide Fuel Cell Anodes

This study presents an experimental effort to elucidate the role of CeO2-x in composite SOFC anodes, by characterizing electrochemical oxidation of small fuel molecules (H2, CO) on thin-film ceria anodes. Thin ceria films were sputter-deposited onto thick YSZ-electrolyte-supported button cells with highsurface-area, porous LSM/YSZ cathodes. The mixed ionicelectronic conductivity of ceria provides multiple reaction pathways for electrochemical oxidation and electrochemical characterization of the ceria films over a range of gas compositions at temperatures from 650 to 850 °C provide a basis for elucidating the importance of competing mechanisms for fuel oxidation on the ceria. Analysis of the experiment results provides a basis for formulating a micro-kinetic mechanism for the oxidation of small fuel species on ceria anodes which can be implemented in SOFC modeling efforts for optimizing ceria-based composite anodes.
Crop and Soil Responses to Fertilization with Distillers’ Grains–Derived Manure in a Saskatchewan Soil

A 2-year field trial was conducted to evaluate crop and soil responses to application of manure from cattle fed distillers’ grain (DGM) in comparison with manure from cattle fed regular barley grain (BGM). Manure addition in general promoted grain and straw yield and increased plant nitrogen (N) and phosphorus (P) uptake in both years by approximately 30–50%. In the first year, effect of manure type on crop responses was insignificant, which is consistent with the similar chemical composition of both manures. In the second year, P recovery was greater in DGM treatments, presumably related to a relatively greater P in DGM. Manure application in general increased soil residual nitrate nitrogen (NO3– N) and available P contents at 0–15 cm deep. The high background fertility of studied soil together with the excess moisture during the second year may have masked the significant effects of manure type on most crop and soil responses during this study.
A study of antioxidant and antiulcer activity of Zizyphus xylopyrus

Aim: Zizyphus xylopyrus (Retz.) Willd. (Rhamnaceae) is used in folk medicine for treating ulcer, as an antinociceptive, antidepressant, anticonvulsant, antioxidant and anti-inflammatory. The major aim of this study was to evaluate the antiulcer and antioxidant activity of Z. xylopyrus. Method: Antiulcer activity of Z. xylopyrus leaf extracts and fractions (50 mg/kg, b.w., orally) were evaluated employing HCl/EtOH induced gastric ulcer and stressinduced acute gastric lesion ulcer models in rats. Whereas, the antioxidant activity of Z. xylopyrus leaf extracts and fractions have been assayed using in vitro methods like 2, 2-diphenyl-1-picrylhydrazylhydrate (DPPH) assay, nitroblue tetrazolium chloride (NBT) assay, reductive ability and superoxide anion scavenging activity. Results: The percent inhibition of aqueous precipitate fraction of ethyl acetate extract was found to be 93% and 92% compared to the standard drug ranitidine in treated group of animals. Similarly, the aqueous precipitate fraction showed a significant (P<0.01) dose-dependent decrease in the index of ulcerative lesion produced in both models in rats when compared to the standard drug ranitidine (20 mg/kg, b.w. orally). Ethanolic extract and the ethyl acetate fraction of Z. xylopyrus also showed prominent antioxidant activity. Conclusion: Results obtained from the present work, it can be inferred that ethanolic extracts and the aqueous precipitate of Z. xylopyrus must have secondary metabolites contributing to the stated activities. Further an exhaustive phytochemical work is needed in order to isolated, characterize and perform bioassays for the compound providing anti-oxidant and anti-ulcer activity.

Conceptual design analysis of a compressor‐driven sorption cooling system

The feasibility of using activated carbon/nitrogen pair as an alternative to metal hydride–hydrogen combination in a compressor‐driven sorption refrigerator (CDSR) has been studied in the present article. The motivation behind the selection of this particular adsorbent/adsorbate pair is due to its high heat of adsorption/desorption, in addition to the fact that nitrogen is absolutely eco‐friendly and a nonhazardous gas to handle with. A conceptual design of the cooling system has been envisaged for near room temperature applications with this activated carbon/nitrogen pair. In order to evaluate the performance of the CDSR system, mathematical models have been developed separately for the adsorption and desorption processes involving transient heat and mass transfer analysis. The present analysis also helped to conduct a parametric evaluation of the cooling system. Copyright © 2009 John Wiley & Sons, Ltd.
Use of Evaporation for Heavy Oil Produced Water Treatment

Heavy oil recovery processes have traditionally used once through steam generators (OTSG) to produce high pressure steam for injection into geological formations containing heavy oil. The heat given up by the condensing steam fluidizes the heavy oil and allows the oil/water mixture to be brought to the surface. The oil is recovered as product and the water, referred to as produced water, is de-oiled and treated for feedwater to the OTSG. The typical treatment method for produced water is warm or hot lime softening (WLS or HLS), filtration, and weak acid cation exchange (WAC). An alternative method of produced water treatment is vertical tube, falling film, vapour compression evaporation. This method: 1) eliminates physical-chemical produced water treatment; 2) results in lower life cycle costs; 3) does not produce any softener sludge for disposal; 4) minimizes the number and volume of waste streams requiring disposal; 5) requires fewer maintenance materials and less maintenance labour; 6) reduces the required amount of produced water de-oiling equipment; 7) dramatically increases OTSG feed water quality, improving OTSG reliability; and, 8) provides increased system availability and reliability. For steam assisted gravity drainage (SAGD) processes, which require 100% quality steam, it has the added advantage of producing water of sufficient quality for use in standard packaged boilers in lieu of OTSG. Packaged boilers are less expensive than OTSG, produce a much smaller liquid blowdown stream, and result in a boiler feed system which is 20% smaller than that of an OTSG.

Equity Volatility Term Structures and the Cross Section of Option Returns

The slope of the implied volatility term structure is positively related to future option returns. I rank firms based on the slope of the volatility term structure and analyze the returns for straddle portfolios. Straddle portfolios with high slopes of the volatility term structure outperform straddle portfolios with low slopes by an economically and statistically significant amount. The results are robust to different empirical setups and are not explained by traditional factors, higher-order option factors, or jump risk.
Analytical investigations of an electron–water molecule pseudopotential. I. Exact calculations on a model system

Exact quantum mechanical calculations on the excess electronic states of the electron–water molecule system have been performed in the static-exchange approximation. The computational model includes a steep, but smooth confining potential which keeps the excess electron in the vicinity of the neutral molecule. Elimination of the core states of the water molecule by the application of the Phillips–Kleinman repulsion operator, and the removal of the large core oscillations of the wave function of the excess electron by the linear combination of the core states and the valence state result in a smooth pseudo-wave function. The pseudo-wave function has proper asymptotic behavior with the correct eigenvalue, and, thus, can serve as a model for comparisons to test the validity of various approximations employed in electron–molecule pseudopotential theory. From the comparisons we conclude that of the most commonly used approximations for the repulsion and the exchange operators only the combination of the local .
Synthesis, Characterization, Singlet‐Oxygen Photogeneration, DNA Photocleavage and Two‐Photon‐Absorption Properties of Some (4‐Cyanophenyl)porphyrins

A series of (4-cyanophenyl)porphyrins have been prepared and structurally characterized by 1H NMR, IR and UV/Vis spectroscopy, mass spectrometry, and elemental analysis. The relative singlet-oxygen quantum yields, two-photon absorption cross-sections and DNA photocleavage activities of these porphyrins were measured. The results show that (4-cyanophenyl)porphyrins with a properly designed hydrophobic/hydrophilic balance for better cellular uptake have potential application in two-photon-absorption photodynamic therapy.

WIRELESS DATA ACQUISITION SYSTEM FOR PHARMACEUTICAL AND CHEMICAL INDUSTRIES USING LOAD-CELL

Data acquisition system possesses various applications in numerous fields. Pharmaceuticals companies and chemical industries find importance of data acquisition system while acquiring and storing data related to weights and quantities of different chemicals and compounds. Such a system uses a load cell to measure the weights/volume of the chemicals and stores the data in a computer for later reference. These modules are also used in condiment stores where the weight/quantity of the commodity is found using the load cell, data is sent to the computer which then decides the cost of it. Use of such system reduces the need of manually creating a database which may lead to errors. This paper describes a similar system with an additional feature of wireless communication using ZigBee protocol. The weight measured, can be monitored from long distance by sending it to another module through wireless system which is then sent to the database. Low power consumption, low cost, accurate measurement and the flexible structure are the characteristics of this module.
Effect of Shallow-Buried High-Intensity Mining on Soil Water Content in Ningtiaota Minefield

Shallow-buried high-intensity mining (SHM) activities commonly in China’s western mining area will lead to the decrease of groundwater level and soil water content (SWC), which will aggravate the further deterioration of the local fragile ecological environment. In this study, the applicability and limitations of six typical soil dielectric models were comprehensively evaluated based on ground penetrating radar (GPR) technology and shallow drilling methods. Moreover, experiments were performed to test the variation of SWC in Ningtiaota minefield affected by the SHM. The results show that the fitting effect of the four empirical models and two semi-empirical models on the clay is better than that of the medium sand. Among the six models, the Ledieu model has the best performance for medium sand, and the Topp model for clay. After SHM, the shallow SWC decreases as a whole. The decreasing range is 4.37–15.84%, showing a gradual downward trend compared with the one before mining. The shorter the lagging working face distance, the greater the drop of SWC will be. The longer the lagging working face distance, the smaller the drop of SWC will be showing a gradual and stable trend.
Exploring mental models of the right to informational self-determination of office workers in Germany

Abstract Applied privacy research has so far focused mainly on consumer relations in private life. Privacy in the context of employment relationships is less well studied, although it is subject to the same legal privacy framework in Europe. The European General Data Protection Regulation (GDPR) has strengthened employees’ right to privacy by obliging that employers provide transparency and intervention mechanisms. For such mechanisms to be effective, employees must have a sound understanding of their functions and value. We explored possible boundaries by conducting a semi-structured interview study with 27 office workers in Germany and elicited mental models of the right to informational self-determination, which is the European proxy for the right to privacy. We provide insights into (1) perceptions of different categories of data, (2) familiarity with the legal framework regarding expectations for privacy controls, and (3) awareness of data processing, data flow, safeguards, and threat models. We found that legal terms often used in privacy policies used to describe categories of data are misleading. We further identified three groups of mental models that differ in their privacy control requirements and willingness to accept restrictions on their privacy rights. We also found ignorance about actual data flow, processing, and safeguard implementation. Participants’ mindsets were shaped by their faith in organizational and technical measures to protect privacy. Employers and developers may benefit from our contributions by understanding the types of privacy controls desired by office workers and the challenges to be considered when conceptualizing and designing usable privacy protections in the workplace.
