Abstract:
Nonprofit arts organization the ZBS Foundation began as a “media commune” in the early 1970s and continues to the present day: a period that spans dramatic changes in American radio culture and audio technology. The key creative figure at ZBS is the writer and producer Thomas Lopez, whose work serves as a case study in a “post-network” style of radio drama, one shaped by multitrack editing, field recording, and the ethos of the 1960s counterculture. The ZBS aesthetic comes into sharpest focus in the Jack Flanders adventure series, which demonstrates how ZBS adapted a “theater of the mind” approach to radio drama to create a “theater of the mind-body” that re-accentuated earlier conventions of the radio adventure serial for a countercultural audience. Lopez’s increasing use of field recordings to structure his narratives established a formal tension between the inner exploration of the hero’s psyche and an encounter with different cultures. I chart the development of this formal tension in ZBS’s theater of the mind-body and argue that Lopez’s work with ZBS is a bridge across multiple eras of radio, an archive of enduring characters and distinctive styles of storytelling, and a sonic laboratory for the fostering of cultural dialogue through sound.

Abstract:
An efficient mobility management for mobile stations plays an important role in mobile communication networks. Two basic operations of mobility management are location registration and paging. A zone-based registration (ZBR) is implemented in most of the mobile communication networks and we consider the mobility management scheme that combines a zone-based registration and a selective paging (SP). We propose a new analytical model that can reflect the characteristics of the ZBR smoothly where location areas of the ZBR are set up so that regions such as roads, bridges, rivers and mountains, where there is relatively little traffic, will constitute their boundaries. We adopt a revised 2-dimensional random walk mobility model to consider such characteristics. In addition, we propose a more efficient division scheme of location area for 2-step selective paging. We evaluate the performance of the mobility management scheme using our mobility model to determine the optimal size of a location area that will result in the minimum signaling traffic on radio channels. Numerical results are provided to demonstrate that our mobility model is useful to evaluate the ZBR more exactly. The results of this study can be used effectively in analyzing and comparing the performances of various mobility management schemes.

Abstract:
AbstractThe effective resistivity (ρeff) is a figure of merit commonly used to assess the radio-frequency performance of a substrate from the measurements of coplanar waveguide lines. For highly resistive substrates, such as the trap-rich (TR) substrate, the extracted ρeff decreases by several orders of magnitude at millimeter-wave frequencies. The explanation for this decay is twofold. First, the imaginary part of the characteristic impedance ${\rm \lpar \Im }\lpar Z_c\rpar \rpar$ is not well extracted, which leads to an incorrect separation of the total losses among the metal and substrate losses. Second, the original expression of ρeff does not include dielectric losses, which might become non-negligible at millimeter-wave frequencies. This paper solves both issues by presenting a new procedure to extract ρeff and the dielectric losses simultaneously, and by introducing a novel method to correct ${\rm \Im }\lpar {Z_c} \rpar$. Furthermore, it is shown that this extraction method enables the correct extraction of substrate parameters up to 220 GHz of TR and high-resistivity silicon substrates. Finally, the origin of the large extracted value of dielectric loss is discussed in the potential presence of surface roughness and surface wave radiation. Both phenomena are discounted thanks to measurements of an additional reflective structure and a standard impedance substrate.

Abstract:
Abstract Effects of naturally existing rare-earth metals (REMs; atomic numbers, 39, 57D60, 62D71; Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), added as chloride salts, on Ca2+ influx induced by two different stimuli, namely hypoosmotic shock and hydrogen peroxide, were examined in a suspension-cultured transgenic cell line of BY-2 tobacco cells expressing aequorin, a Ca2+-sensitive luminescent protein in cytosol. Most REM salts used here showed inhibitory effect against Ca2+ influx. Especially NdCl3, SmCl3, EuCl3, GdCl3 and TbCl3 showed the most robust inhibitory action. In contrast, LuCl3, YbCl3, ErCl3 and YCl3 were shown to be poor inhibitors of Ca2+ influx. Since REMs tested here form a sequential range of ionic radii from 86.1 to 103.2 pm and the optimal range of ionic radii required for blocking the flux of Ca2+ was determined for each stimulus. The hydrogen peroxideinduced Ca2+ influx was optimally blocked by REMs with a broad range of ionic radii (93.8D 101 pm) which is slightly smaller than or similar to that of Ca2+ (100 pm), while the hypoosmotically induced flux of Ca2+ was inhibited optimally by few REMs with a narrower range of relatively smaller ionic radii around that of Gd3+ (93.8 pm) a well known inhibitor of stretch-activated channels. Possible applications of such series of channel blockers in elucidation of plant signal transduction pathways are encouraged

Abstract:
Abstract Pea protoplasts dielectrophoretic coefficients were measured in alternating electric fields of frequency 1 M Hz and voltage 5 V applied between two concentric cylindrical metal electrodes of outer and inner radii 0.24 mm and 1 mm, respectively. They do not vary significantly with solution osmolarity, but show a clear expressed maximum in isotonic conditions; the values in 0.4 ᴍ, 0.5 ᴍ, 0.6 ᴍ and 0.7 ᴍ manitol solutions are (6.5, 10.2, 8.8 and 5.6) × 10−24 A2s4/Kg, pectively. The average cell radii in those conditions are 14.2 µm, 14.6 µm, 13.8 µm and 13.6 µm. The radii of cell-to-electrode contacts follow the same dependence on the osmolarity as the dielectrophoretic coefficients; they do not depend on the applied voltages up to 18V. The times of cell approach near to the electrode were too short to be explained by the action only of the dielectrophoretic force; consequently an attractive force appeared at very close approach. These results may be of use in future studies of membrane adhesion and fusion.

Abstract:
DNA repair is critical for successful chemo- and radiotherapy of human tumours, because their genotoxic sensitivity may vary in different types of cancer cells. In this study we have compared DNA damage and the efficiency of its repair after genotoxic treatment with hydrogen peroxide, cisplatin and γ-radiation of head and neck squamous cell carcinoma (HNSCC). Lymphocytes and tissue cells from biopsies of 37 cancer patients and 35 healthy donors as well as the HTB-43 larynx cancer cell line were employed. The cell sensitivity to genotoxic treatment was estimated by the MTT survival assay. The extent of DNA damage and efficiency of its repair was examined by the alkaline comet assay. Among the examined treatments, we found that HNSCC cells were the most sensitive to γ-radiation and displayed impaired DNA repair. In particular, DNA damage was repaired less effectively in cells from HNSCC metastasis than healthy controls. In conclusion, our results suggest that the different genotoxic sensitivity of HNSCC cells may depend on their DNA repair capacity what in turn may be connected with the effectiveness of head and neck cancer therapy.

Abstract:
Using the technique of pulse radiolysis, it has been demonstrated that thiyl radicals (RS˙) derived from glutathione (GSH), cysteine (CYSH), penicillamine (PnSH) and 2-m ercaptoethanol (M E) interact with oxygen at a high rate. The resulting transient absorption, with a maximum around 540-560 nm, is characteristic of the sulphur peroxyl radical (RSOO˙). The yield and the kinetic of formation of RSOO˙ further support our previous suggestion that thiyl/O2 reaction is an equilibrium. The redox properties of RSOO˙ are discussed on the basis of the interaction with reductants. Studies on the radio-induced enzyme inactivation in the presence of thiols seem to suggest a damaging role for RSOO˙ radicals.

Abstract:
Reactions involving lipase-catalyzed interesterification of lipids, which are of commendable interest in biotechnology, have been monitored and assayed by radiochemical methods using 14C-labeled substrates. Medium chain (C12 plus Cu) triacylglycerols were reacted in the presence of an immobilized lipase from Mucor miehei and hexane at 45 °C with methyl [1-14C]oleate. [1-14C]oleic acid, [carboxyl-14C]trioleoylglycerol. [1-14C)octadecenyl alcohol, and [U-14C)glycerol, each of known specific activity. The reactions were monitored and the rate of interesterification determined by radio thin layer chromatography from the incorporation of radioactivity into acyl moieties of triacylglycerols (from methyl oleate, oleic acid, and trioleoylglycerol), alkyl moieties of wax esters (from octadecenyl alcohol), and into glycerol backbone of monoacylglycerols and diacylglycerols (from glycerol).

Abstract:
Abstract Astragali radix (AR), known in China as huangqi, is commonly used in traditional Chinese medicine. Water soluble extractive (WSE) values play an important role in the quality evaluation of herbal drugs. In this study, WSE of wild and cultivated AR were compared systematically. The WSE value of cultivated AR was significantly higher than that of the wild AR, and their UV-absorbance in the range of 250–400 nm was also different. The chemical compositions of different WSE were further compared by 1H NMR spectroscopy combined with multivariate analysis. Results from the principal component analysis and the hierarchical cluster analysis showed a clear separation between the WSEs of wild and cultivated AR. The differential metabolites responsible for the separation were identified by orthogonal projections to latent structures discriminant analysis and recursive support vector machine. The WSE of wild AR contained more arginine, valine, threonine, asparagine, succinate, and glutamine, while the cultivated AR contained more sucrose. Thus, the WSE can be used as a simple and reliable method for discrimination of wild and cultivated ARs, and the results obtained in this study extend the potential use of WSE in the quality evaluation of herbal drugs.

Abstract:
Abstract The zebrafish has emerged as an excellent vertebrate model for analysis of hematopoietic and leukemogenic development. Blood production in adult zebrafish occurs in the kidney marrow (KM), within the peritubular kidney interstitium, while kidney tubules support renal functions. To study the molecular mechanisms of stem cell specification and fate decision, we developed transgenic zebrafish expressing EGFP either at distinct hematopoietic levels using the zebrafish SCL/TAL1, RAG2, and FLI1 promoters, or in all tissues using the zebrafish β-actin promoter. KM progenitor cells from the SCL-EGFP, FLI1-EGFP, RAG2-EGFP, and ZBA-EGFP transgenic zebrafish were separated by FACS based on previously described method. The kinetics of KM progenitor cell transplantation from transgenic zebrafish into adult and embryonic recipients was analyzed. Visualization of donor cells in embryonic and adult recipients allowed us to detect trafficking and multilineage reconstitution in transplanted recipients in real-time. Transplantation of whole KM to unconditioned adult recipients resulted in the disappearance of donor-derived cells within 3 weeks. Thus, efficient engraftment of donor cells required host conditioning using β radiation or busulfan. Dose response experiments indicated that the minimum lethal dose of radiation averaged between 38 and 54 Gy, and was strain-dependent since hematolymphoid ablation of the Ek strain required higher radiation doses compared to the AB* strain. Sublethal irradiation doses of 25 Gy predominantly ablated lymphocytes and permitted transplantation of lethal TEL-AML1-induced pre B-cell leukemia. All irradiated animals not receiving transplants showed 10–50 fold decrease in all hematopoietic lineages at one week, and then died by 3 weeks post-radiation. In contrast, 60% of animals that received a transplant survived for at least 3 months. FACS analysis indicated that the frequency of EGFP-positive KM progenitors from the ZBA-EGFP (Common progenitors), the FLI1-EGFP (Hematopoietic-endothelial progenitors), and the RAG2-EGFP (Lymphoid progenitors) averaged 7%, 0.6%, and 4%, respectively. FACS-sorted EGFP+ donor cells were transplanted into adult wild-type irradiated recipients or blastula stage embryos. Transplantation of donor ZBA-EGFP KM cells resulted in engraftment and detection of donor-derived hematopoietic cells of all lineages within 2–3 weeks. No overt signs of graft-versus-host disease or graft rejection were detected. Transplantation of KM endothelial progenitors or angioblasts from the FLI1-EGFP transgenic fish resulted in endothelial homing and appearance of donor-derived intersegmental vessels in recipient fish 3–4 weeks post-transplant. These data demonstrate that marrow-derived angioblasts reconstitute endothelium of adult zebrafish, and represent, to our knowledge, the first evidence for a marrow derived hematopoietic-endothelial precursor homing to the vasculature of a transplanted vertebrate. Embryonic transplantation of 2×103 to 3×103 cells to blastula stage embryos resulted in dose-dependent lineage-faithful contribution of the transplanted cells to the developed embryos. We are investigating whether single transplanted progenitor cells sorted from SCL-EGFP KM engraft wild-type and SCL-depleted recipients, and provide long-term survival when transplanted to GATA1−/− and RUNX1−/− mutants. Transplantation of KM progenitors in zebrafish is sufficient for radio- and chemoprotection, and provides an excellent system to analyze oncogenic transformation, stem cell engraftment and immune cell function.

Abstract:
A primary requirement of any reactor design or process development computation is knowledge of the major properties of the compounds involved. Although most of these can be obtained from the literature, there is still a need to estimate them from correlations. The main difficulty is the large number of correlations proposed for a given property and the need to select the best from among them. No single correlation works with equally high precision under all conditions. On the other hand, correlations that can be used with acceptable levels of precision over a wide range of conditions are also available for a number of properties. The slight sacrifice of accuracy is often more than compensated for by the ease and generality of application of these methods. Our emphasis here will be on such correlations. For a detailed treatment, reference should be made to books devoted exclusively to properties estimation. The book by Reid, Prausnitz, and Poling (1987), along with its earlier versions by Reid and Sherwood (1958, 1966) and Reid, Prausnitz, and Sherwood (1977), and the works of Janz (1958), Hansch and Leo (1979), and Lyman, Reehl, and Rosenblatt (1982) are noteworthy. The following methods selected for a few properties are based in part on the recommendations contained in these treatises. The two most important bases for formulating correlations for estimating the properties of organic compounds (indeed of any compound) are the law of corresponding states (LCS), and the method of group contributions (GC). LCS is based on the concept that all substances exhibit identical properties under conditions equally removed from their critical states. The “equally removed” state for any property is usually expressed as the ratio of its value at that state to the value at the critical state and is referred to as the reduced property. Thus Tr — T/TC, Pr = P/PC, Vr = V/Vc and ηr = η/ ηc are the reduced temperature, pressure, volume, and viscosity, respectively. If the simple ideal gas law PV/RgT — Z, where Z is the compressibility, can be recast in terms of reduced properties as PrVt/RgTr = Z/ZC, then the PVT behavior of all fluids can be represented as Pr versus Tr plots for different values of Zr.

Abstract:
Three Way Catalysts (TWC) are extensively used for simultaneous control of three principal automotive pollutants, namely carbon monoxide (CO), Oxides of nitrogen (NOx), and hydrocarbon (HC). Most of works on three way catalytic converter have been carried out with noble metals such as Platinum, Rhodium, and Iridium have been tried individually and in different combinations and proportions. Noble metal catalysts give very good performance of reduction of (NOx), CO and HC in the narrow range of stoichiometric Air Fuel ratio. Noble metals are costly and not abundantly available. These draw backs of the noble metal catalysts have inspired to search for the alternative catalysts, which will perform well over the wide range of A/F ratio and are economical and abundantly available. This paper discusses the processing of ZSM-5 to Cu-Ion- Exchanged ZSM-5, ZSM-5 supported Cu-Pt bimetallic catalyst and Cu-Rh bimetallic catalyst and placing them in a three staged converter to study the reduction efficiencies of exhaust emissions CO, NOx, and HC in a 800 cc Maruti S. I. Engine. The experiments are carried out at 1500 rpm, 17.6 A/F ratio, different catalyst bed temperatures and different engine loads 0%, 17.5%, 35%, 52.5%, and 70% of full load. The results achieved are the maximum reduction of CO 90% at 375 °C NOx 90% at 375 °C and HC 61% at 380 °C. The same engine was also run for Noble metal converter (NMC) (EURO-II) purchased from an authorized Maruti distributor and the maximum reduction achieved were CO 89% at 375° C, NOx 91% at 375° C, and HC 70% at 390° C comparable to Zeolite Catalytic Converter (ZCC).
