READING AND INTERPRETING DIAGNOSTIC DATA FROM VEHICLE OBDII SYSTEM (2005)

This paper presents reading and interpreting diagnostic data from vehicle OBDII (On-Board Diagnostics II) system using a PC-based diagnostic tester. The current work represents the data link layer and the application layer of a diagnostic tester project. The paper begins with a brief description of the diagnostic protocols. The ISO 9141-2 and ISO 14230 protocols have been chosen for implementation mainly because they share the same physical interface. The diagnostic software is developed using C++ language utilizing Qt© cross platform toolkit. The connection to physical layer, data link layer and application layer are represented by the DtConnection-, DiagMessage- and DiagService class hierarchies respectively. Various data items from OBDII system are read and interpreted, such as: VIN, DTCs, engine RPM, and so on. The GUI (Graphic User Interface) of the program is a simple window with text field, menus and buttons for user commands. The diagnostic tester is successfully verified in practice and results are provided.

It includes such enduringly popular poems of the war as Brooke's sonnets and McCrae's In Flanders Fields. There are also examples of the once hugely popular poems which were written as propaganda. Historical and biographical background material, extracts from diaries, personal letters and autobiographies illuminate the poetry. Poets featured include Wilfred Owen, Siegfried Sassoon, Edward Thomas, Charles Sorley, Isaac Rosenberg, Herbert Read, Robert Graves, Vera Brittain, Rose Macauley, Eleanor Farjeon, D.H. Lawrence, John Galsworthy, Edmund Blunden, Thomas Hardy, Rudyard Kipling, Walter de la Mare, John Masefield, Lawrence Binyon, John McCrae, Ivor Gurney, John Oxenham, Arthur Graeme West and Rupert Brooke.
X-ray Diffraction Structure Analysis of MCM-48 Mesoporous Silica (2005)

The structure of MCM-48 mesoporous silicate materials has been fully characterized from X-ray diffraction data by applying recently developed methods of mesostructure analysis and full-profile refinement. The pore wall thickness of both as-made and calcined MCM-48 was determined with high precision to be 8.0(1) Angstrom. No regular variations of the wall thickness were detected, but its density was found to be ca. 10% higher in the low-curvature regions. The surfactant density in the pores was assessed around 0.6-0.7 g/cm(3) and was found to have a distinct minimum in the pore center similar to that detected previously in MCM-41. A new extended model function of the density distribution in MCM-48 is proposed on the basis of the structural features that were revealed.
Gut Epithelial Cells as Targets for Gene Therapy of Hemophilia (1997)

Gut epithelium is an attractive target for gene therapy of hemophilia due to the large number of rapidly dividing cells that should be readily accessible to a wide range of vectors by a noninvasive route of administration. We have performed in vitro tests to determine the suitability of gut epithelial cells for gene transfer, protein synthesis, and secretion of coagulation factors VIII and IX. The results with retroviral vectors indicate that transduced epithelial cells from human, rat, or porcine small or large intestine can synthesize significant amounts of factor VIII or factor IX and that two-thirds or more of the recombinant protein is secreted in a basolateral direction (i.e., away from the lumen and toward underlying capillaries and lymphatics). Furthermore, we have demonstrated that intestinal epithelial cells are susceptible to efficient gene transfer by lipofection and adenovirus vectors. In the case of factor IX, we have produced a high-titer adenovirus vector capable of transducing gut epithelial cells resulting in synthesis of factor IX. The results of our in vitro studies indicate that gene transfer targeting gut epithelium as a new approach to hemophilia gene therapy is rational and merits in vivo studies in hemophilia animal models.
High octane gasoline from field butanes by the UOP indirect alkylation (InAlk{sup TM}) process (1998)

Processes that convert low value LPG to higher value gasoline are very important to the petroleum refining industry. Historically the most important of these has been paraffin alkylation using either hydrofluoric or sulfuric acid. However, use of strong liquid acids is now perceived as threatening to the environment. As a result much recent research has been done to find an alternate processing route. However, another factor has even more recently emerged, that is the increasing amount of n-butane coming onto the market; it cannot be processed by conventional alkylation or any similar direct alkylation route because these routes require equimolar amounts of isobutane and butenes (iso-or n-). Thus UOP is introducing the InAlk Process which uses environmentally safe solid catalysts to process any mix of butanes and butenes. Even though n-butane is a feed, InAlk-derived gasoline is several octane numbers higher than gasoline from hydrofluoric or sulfuric acid-catalyzed alkylation. The InAlk Process requires three reactions, however, the process does not result from combining three separate processes. In fact, an important aspect of InAlk is that the three reactions are complementary and well-set up for integration into one process. The three catalytic reactions occurring during InAlk are: dehydrogenation, oligomerization and hydrogenation. Oligomerization is the critical step for determining product branching; since a mild acid is used for this step compared to hydrofluoric or sulfuric acids, less cracking and isomerization occurs resulting in a very high octane number product.

Signal and noise separation; art and science (1999)

Abstract The separation of signal and noise is a central issue in seismic data processing. The noise is both random and coherent in nature, the coherent part often masquerading as signal. In this tutorial, we present some approaches to signal isolation, in which stacking is a central concept. Our methodology is to transform the data to a domain where noise and signal are separable, a goal that we attain by means of inversion. We illustrate our ideas with some of our favorite transformations: wavelets, eigenvectors, and Radon transforms. We end with the notion of risk, baseball, and the Stein estimator.
Co-management of cataract and glaucoma in the era of minimally invasive glaucoma surgery (2017)

Cataract and glaucoma frequently exist together. Because the field of glaucoma surgical care is expanding and cataract surgery is becoming progressively safer, it is important to frequently re-evaluate our treatment paradigms. We review and evaluate current studies and treatment options.
Hexamethylene bisacetamide in myelodysplastic syndrome and acute myelogenous leukemia: a phase II clinical trial with a differentiation- inducing agent (1992)

Hexamethylene bisacetamide (HMBA) is a potent inducer of differentiation of a number of transformed cell lines in vitro. We report results of a phase II clinical trial in 41 patients with myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML) to whom HMBA was administered by continuous infusion for 10 days and repeated after an interval of 18 to 75 days. HMBA induced a complete remission (CR) in three patients and a partial remission (PR) in six patients. The median duration of CR was 6.8 months (range 1.3 to 16 months) and 3.7 months for PR (range 1 to 7 months). No significant difference was observed between responders and nonresponders with respect to the mean HMBA plasma levels, which were 0.86 +/- 0.04 mmol/L and 0.87 +/- 0.12 mmol/L, respectively. In certain patients morphologic and chromosome analyses provided evidence that HMBA induced differentiation of transformed hematopoietic precursors. The most prominent toxicity was thrombocytopenia, generally reversible on cessation of administration of HMBA.
Curcumin Induces the Differentiation of Myeloid-Derived Suppressor Cells and Inhibits Their Interaction with Cancer Cells and Related Tumor Growth (2011)

Myeloid-derived suppressor cells (MDSC) accumulate in the spleen and tumors and contribute to tumor growth, angiogenesis, and progression. In this study, we examined the effects of curcumin on the activation and differentiation of MDSCs, their interaction with human cancer cells, and related tumor growth. Treatment with curcumin in the diet or by intraperitoneal injection significantly inhibited tumorigenicity and tumor growth, decreased the percentages of MDSCs in the spleen, blood, and tumor tissues, reduced interleukin (IL)-6 levels in the serum and tumor tissues in a human gastric cancer xenograft model and a mouse colon cancer allograft model. Curcumin treatment significantly inhibited cell proliferation and colony formation of cancer cells and decreased the secretion of murine IL-6 by MDSCs in a coculture system. Curcumin treatment inhibited the expansion of MDSCs, the activation of Stat3 and NF-κB in MDSCs, and the secretion of IL-6 by MDSCs, when MDSCs were cultured in the presence of IL-1β, or with cancer cell- or myofibroblast-conditioned medium. Furthermore, curcumin treatment polarized MDSCs toward a M1-like phenotype with an increased expression of CCR7 and decreased expression of dectin 1 in vivo and in vitro. Our results show that curcumin inhibits the accumulation of MDSCs and their interaction with cancer cells and induces the differentiation of MDSCs. The induction of MDSC differentiation and inhibition of the interaction of MDSCs with cancer cells are potential strategies for cancer prevention and therapy.
Generation Of High Energy Tunable Picosecond Pulses (1985)

We describe a simple system for the generation of tunable picosecond pulses in the millijoule range. The system consists of an active/passive mode-locked Nd:YAG pump laser which emits a single pulse, and the dye laser part which employs a single mode short cavity dye laser and two double pumped amplifiers.
Towards a test standard for board and system level mixed-signal interconnects (2002)

This paper describes basic requirements for a standard bus for testing analog interconnects. The viewpoint is that of prospective users. An architecture for such a standard bus is proposed. The basic conception is of a mixed-signal version of boundary-scan and is compatible with, indeed built upon, ANSI/IEEE Std 1149.1. The goals in mind are the detection of faults and the measurement of analog interconnect parameters. Among the desired benefits are test and test data commonality throughout an assembly hierarchy, from manufacturing to field service.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Cannabidiolic acid prevents vomiting in <i><scp>S</scp>uncus murinus</i> and nausea‐induced behaviour in rats by enhancing 5‐<scp>HT<sub>1A</sub></scp> receptor activation (2012)

Compared with cannabidiol, CBDA displays significantly greater potency at inhibiting vomiting in shrews and nausea in rats, and at enhancing 5-HT(1A) receptor activation, an action that accounts for its ability to attenuate conditioned gaping in rats. Consequently, CBDA shows promise as a treatment for nausea and vomiting, including anticipatory nausea for which no specific therapy is currently available.
Novel algorithm for accelerated second zone tripping of non-unit distance protection (2001)

Today, distance protections are widely used to protect HV and VHV lines. In order to save the communication channels, they can be operated in a nonunit scheme. This paper describes an algorithm based on the detection of the circuit breaker opening at the distant line terminal and gives an estimation of its overall performance depending on different parameters.
An approach to mixed circuits testing (2002)

A test stimuli generation and a signature analysis method are proposed for a mixed mode circuits. The processes are based on a catastrophic fault model simulated at the transistor level, and on a measure of the transient response of the current used by the circuit when applying the stimuli. A built-in dynamic current sensor is proposed in order to perform the transient analysis of the current used in an actual ATE systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Algunos problemas de optimización geométrica (2015)

espanolLos problemas de optimizacion han sido estudiados de forma recurrente desde la epoca de los griegos. En sus inicios estos problemas nacen de cuestiones puramente geometricas, como el problema de la Reina Dido. Las tecnicas de demostracion eran muy ingeniosas, pero particulares a cada caso.

Analysis of Volatile Compounds Released during the Grinding of Roasted Coffee Beans Using Solid-Phase Microextraction (2003)

A dynamic solid-phase microextraction (SPME) method to sample fresh headspace volatile compounds released during the grinding of roasted coffee beans was described and the analytical results using gas chromatography/mass spectrometry (GC/MS) and GC/olfactometry (GC/O) were compared to those of the conventional static SPME sampling methods using ground coffee. Volatile compounds released during the grinding of roasted coffee beans (150 g) were obtained by exposing the SPME fiber (poly(dimethylsiloxane)/divinylbenzene, PDMS/ DVB) for 8 min to nitrogen gas (600 mL/min) discharged from a glass vessel in which the electronic coffee grinder was enclosed. Identification and characterization of volatile compounds thus obtained were achieved by GC/MS and GC/O. Peak areas of 47 typical coffee volatile compounds, separated on total ion chromatogram (TIC), obtained by the dynamic SPME method, showed coefficients of variation less than 5% (n = 3) and the gas chromatographic profile of volatile compounds thus obtained was similar to that of the solvent extract of ground coffee, except for highly volatile compounds such as 4-hydroxy-2,5-dimethyl-3(2H)-furanone and 4-ethenyl-2-methoxyphenol. Also, SPME dilution analysis of volatile compounds released during the grinding of roasted coffee beans showed linear plots of peak area versus exposed fiber length (R (2) > 0.89). Compared with those of the headspace volatile compounds of ground coffee using GC/MS and GC/O, the volatile compounds generated during the grinding of roasted coffee beans were rich in nutty- and smoke-roast aromas.
Isotope dilution mass spectrometry as a calibration method for the analysis of trace elements in powder samples by LA-ICP-MS (2003)

The applicability of the isotope dilution (ID) technique for trace element determinations in powdered solid samples by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is demonstrated. LA-ICP-IDMS combines the advantage of the isotope dilution technique as a definitive method with the powerful capability of LA-ICP-MS for a fast and direct multi-element analysis of solid samples. LA-ICP-IDMS therefore allows matrix-matched quantification of element concentrations without any external standard, which is not possible by other calibration strategies used in LA-ICP-MS, up to now. The sample preparation effort is kept minimal and consists of an addition of the corresponding isotope-enriched spike solutions to the powder sample, subsequent drying and pressing of the isotope diluted sample to a pellet. For quantification, only one isotope ratio per analyte must be measured in the isotope diluted sample. It is shown that this internal standardisation corrects for all signal variations during analysis, e.g. instrumental drift or varying mass ablation rates. The LA-ICP-IDMS method is validated by the analysis of Cr, Fe, Cu, Zn, Sr, Cd, and Pb in seven certified reference materials (BCR 60, BCR 150, BCR 151, SRM 1567a, SRM 1577b, CRM 320, and SRM 1646) of different (organic and inorganic) matrix composition. 28 of a total number of 32 trace element concentrations determined by LA-ICP-IDMS are in agreement within the uncertainties of the certified values. The precision obtained is better than 10% for elements with concentrations >0.03 µg g−1. Only for two samples the Cr and Fe results differ significantly from the certified values.
Ethylene production under high temperature stress causes premature leaf senescence in soybean (2010)

Leaf senescence in soybean (Glycine max L. Merr.) occurs during the later stages of reproductive development and can be triggered or enhanced by high temperature (HT) stress. Ethylene production can trigger premature leaf senescence, but it is unclear whether HT stress produces ethylene and the subsequent influence on physiology and yield of soybean is also uncertain. We hypothesised that ethylene produced under HT stress is involved in premature leaf senescence and that use of an ethylene perception inhibitor would influence physiology and yield. Objectives of this study were to (1) quantify HT-stress-induced ethylene production; (2) quantify effects of HT stress and application of an ethylene perception inhibitor (1-methylcyclopropene; 1-MCP) on source strength traits such as photosynthetic rate, oxidant production, membrane damage and sugar accumulation; and (3) evaluate efficacy of 1-MCP on minimising HT-stress-induced effects on physiological and yield traits. Soybean plants were exposed to HT (38/28°C) or optimum temperature (OT, 28/18°C) for 14 days at the beginning of pod set. Plants at each temperature were treated with 1 µg L–1 1-MCP or left untreated (control). HT stress enhanced ethylene production rates in leaves and pods by 3.2- and 2.1-fold over OT. HT stress decreased photochemical efficiency (5.8%), photosynthetic rate (12.7%), sucrose content (21.5%), superoxide dismutase (13.3%), catalase (44.6%) and peroxidase (42.9%) enzymes activity and increased superoxide radical (63%) and hydrogen peroxide (70.4%) content and membrane damage (54.7%) compared with OT. Application of 1-MCP decreased ethylene production rate and premature leaf senescence traits by enhancing the antioxidant defence system. HT stress decreased seed set percentage (18.6%), seed size (64.5%) and seed yield plant–1 (71.4%) compared with OT, however, foliar spray of 1-MCP increased the seed set percent and seed size, which resulted in a higher yield than the unsprayed control. The present study showed HT stress increased ethylene production rate, which triggered premature leaf senescence, whereas 1-MCP application reduced or postponed premature leaf senescence traits by inhibiting ethylene production.
An implementation of disk objects in the logical machine monitor (1997)

User or program mobility in distributed computing systems is becoming increasingly significant, since users may sometimes change their working locations. This paper proposes a Logical Machine (LM) system that can effectively support software environment migration and resource mapping. The LM partitions the conventional operating systems into two parts: the Logical Machine Operating System (LMOS) and the Logical Machine Monitor (LMM). They are responsible for user service and system resource management, respectively. The LMM provides a machine independent appearance, called the Logical Machine Interface (LMI), for the upper operating system layers to provide the resources they need. In our experimental system, the LMM contains some disk objects that can be bound dynamically. By varying the binds, the users get different disk characteristics. A mobile disk object with the mechanism of block migration on demand is implemented. It can be incorporated with a logical machine migration facility to achieve job migration, i.e., the user can migrate the operating system and disk blocks to the place he or she desires. The mobile disk also simplifies the mechanism of parallel processing when each server reads and processes its data portion locally. With this approach, the system resources can be mapped more flexibly, while transparency to the operating system is retained. © 1997 John Wiley & Sons, Ltd.
Compact magneto-optical trap for rubidium atoms (2005)

The characteristics of a magneto-optical trap (MOT) using small-diameter cooling laser beams are considered. Trapping and cooling of Rb atoms from the surrounding gas of warm atoms takes place in the trap. A compact (140 μm) and stable atomic cloud is obtained with a density of 7 × 1010 cm−3, which is three orders of magnitude higher than the density of the surrounding gas.
