Mechanical Properties of Aeolian Sandy Soil in Central Taklimakan Desert (2001)

Aeolian sandy soil is a kind of peculiar property soil, which was formed in arid or semiarid area. Very loose structure and mobility characterize this kind of soil. This paper presents the results of an extensive laboratory\|testing program carried out to determine the mechanical properties of aeolian sandy soil taken from three sites in Tazhong. The tests included on compressibility and shear strength. The results are presented and discussed as a first step toward a better utilization or improvement of this kind of soil for local construction purposes. From the results of tests on 14 samples the following conclusions are reached:\;(1) The compressibility modulus (\%E s \%) of aeolian sandy soil varies between 50\^00 MPa and 142\^86 MPa, the compressibility coefficient varies between 0.01 MPa -1 and 0\^04 MPa -1 . With a very small compression coefficient of less then 0.1 MPa -1 , aeolian sandy soil belongs to a kind of low compressibility soil. This means this kind of soil is highly incompressible when compacted. The disparity of compressibility modulus are very small in three different geomorphic units, the average \%E s \% of lee slope of barchan is 92\^36 MPa, the average \%E s \% of stoss slope of barchan is 97.52 MPa, and the average \%E s \% of interdune is 78\^085 MPa. The main influence factors to the compressibility are the grain size distribution, mineral component, shape of grain and the initial void ratio.\;(2) The angle of internal friction of aeolian sandy soil varies between 31°55′and 36°19′that lower than alluvial sand. The internal friction angle of three different geomorphic unit samples have very small difference, the average value of lee slope of barchan is 33°42′, stoss slope is 34°12′and the interdune is 32°30′. The main influence factors to the internal friction angle are the grain size distribution, density and roundness. The theoretic cohesive force of aeolian sandy soil is zero. But the shear strength tests could detect cohesive force, the value are in the range of 0.6 kPa to 9.3 kPa. We are deeming that the value \%C\% is a kind of structure force. The vale \%C\% has good correlation with sorting coefficient, the correlation equation is \%C=9.7955-3.5622 S\-\{OS\}\% and the correlation coefficient is -0.85. So the main influence factor of the structure force is grain size distribution.
189. PROSPECTIVE COHORT ANALYSIS OF PRIMARY PYOGENIC INFECTION OF THE SPINE IN INTRAVENOUS DRUG USERS (2011)

Purpose: To evaluate the demographics, presentation, treatment and outcomes of spinal infection in a population of Intravenous Drug Users. Method: Data on all patients with pyogenic spinal infection presenting to a quaternary referral center was obtained from a prospectively maintain database. Results: Over the five-year study period, there were 102 patients treated for Primary Pyogenic Infection of the Spine of which 51 were Intravenous Drug Users (IVDU). Of this IVDU group there were 34 males. Mean age was 43 years (range 25 – 57). Twenty-three had HIV, 43 Hepatitis C and 13 Hepatitis B. All were using cocaine, 26 were also using Heroin and 44 more than three recreational drugs. Thirty patients presented with axial pain with a mean duration of 51 days (range 3–120). Thirty-one were ASIA D or worse with eight ASIA A. Mean Motor Score of patients with deficit was 58.6. Most common ASIA Motor Levels were C4 and C5. Mean duration of neurological symptoms was seven days (range 1–60). Blood parameters on admission were in keeping with sepsis in immunocompromised patients. None had previous surgery for spinal infection. Twenty-sex were receiving IV antibiotics for known spinal infection. 44 patients were treated surgically. 32 had infection of the cervical spine, 9 Thoracic and 3 Lumbar. 22 had a posterior approach alone, 13 had anterior only while 9 required combined. Mean operative time was 263 mins (range 62 – 742). 13 required tracheostomy. 7 required early revision for hardware failure and 2 for surgical wound infection. Mean duration of antibiotic treatment was 49 days (range 28–116). 26 patients had single agent therapy. 17 had MSSA and 17 MRSA. At discharge 28 patients had neurological improvement (mean 20 ASIA points, range 1–55), 11 had deterioration (mean 13, range 1–50) and 5 were unchanged. There were no in-hospital deaths. At 2 years after index admission 13 patients were dead and none were attending the unit for follow-up. Conclusion: Primary pyogenic spinal infection in IVDU’s typically presents with sepsis and acute cervical quadriplegia. Surgical management must be prompt and aggressive with significant neurological improvement expected in the majority of patients.
A Mutant of <italic>Arabidopsis thaliana</italic> That Defines a New Locus for Glycine Decarboxylation (1994)

A novel photorespiratory mutant of Arabidopsis thaliana, designated gld2, was isolated based on a growth requirement for abnormally high levels of atmospheric CO2. Photosynthetic CO2 fixation was inhibited in the mutant following illumination in air but not in atmosphere containing 2% O2. Photosynthetic assimilation of 14CO2 in an atmosphere containing 50% O2 resulted in accumulation of 48% of the soluble label in glycine in the mutant compared to 9% in the wild type. The rate of glycine decarboxylation by isolated mitochondria from the mutant was reduced to 6% of the wild type rate. In genetic crosses, the mutant complemented two previously described photorespiratory mutants of A. thaliana that accumulate glycine during photosynthesis in air due to defects in glycine decarboxylase (glyD, now designated gld1) and serine transhydroxymethylase (stm). Because glycine decarboxylase is a complex of four enzymes, these results are consistent with a mutation in a glycine decarboxylase subunit other than that affected in the gld1 mutant. The two gld loci were mapped to chromosomes 2 and 5, respectively.
Electrochemical Modified Electrodes Based on Metal‐Salen Complexes (2007)

Abstract A general view of the electroanalytical applications of metal‐salen complexes is discussed in this review. The family of Schiff bases derived from ethylenediamine and ortho‐phenolic aldehydes (N,N′‐ethylenebis(salicylideneiminato)—salen) and their complexes of various transition metals, such as Al, Ce, Co, Cu, Cr, Fe, Ga, Hg, Mn, Mo, Ni, and V have been used in many fields of chemical research for a wide range of applications such as catalysts for the oxygenation of organic molecules, epoxidation of alkenes, oxidation of hydrocarbons and many other catalyzed reactions; as electrocatalyst for novel sensors development; and mimicking the catalytic functions of enzymes. A brief history of the synthesis and reactivity of metal‐salen complexes will be presented. The potentialities and possibilities of metal‐Salen complexes modified electrodes in the development of electrochemical sensors as well as other types of sensors, their construction and methods of fabrication, and the potential application of these modified electrodes will be illustrated and discussed.
Electrophoretic evaluation of the mobility of drugs suitable for iontophoresis. (1995)

Iontophoresis is the process of increasing the penetration of drugs for therapeutic purposes using DC electricity. The most important factor for iontophoresis is the formation of drug ions in solution. On this basis, the penetration of any drug applied by iontophoresis might be maximized at an optimal pH. Seven medications were investigated: acyclovir, methylprednisolone sodium succinate, metronidazole, dexamethasone sodium phosphate, minoxidil, lidocaine hydrochloride, and adenine arabinoside monophosphate. Using techniques of paper electrophoresis, we evaluated the influence of pH on the mobility (mu) of the drugs in phosphate buffers at pH 5, 7, and 9. The mu-values were calculated after detecting the drugs on paper with ultraviolet light. The results indicate that the seven drugs had higher mu-values usually at one, but sometimes at two, of the pH values studied. This study suggests that a variation in pH might alter the maximum ionization, and therefore, the optimal mobility for these seven drugs, as well as other drugs, suited to iontophoresis.
Changes in the electrical activity of dog cardiac Purkinje fibres at high heart rates. (1984)

Rate-dependent changes in the electrical activity of dog Purkinje fibres have been studied. At high rates of stimulation the rate of repolarization is greater, the action potential is shorter, the maximum diastolic potential is increased, the pace-maker potential is reduced in amplitude, and on cessation of rapid stimulation there can be a suppression of spontaneous activity. After an increase of the stimulus frequency there is an abrupt shortening of the action potential, which can be attributed to incomplete recovery of the plateau currents; this is followed by a progressive decline in action potential duration over the next several hundred seconds. The factor responsible for the slow changes in duration could also be responsible for the accompanying increase in maximum diastolic potential because this develops along a similar time course. These slow changes in electrical activity have been investigated with the phase-plane technique. They are the result of an increase in the net outward current over a wide range of potentials (approximately -10 to approximately -90 mV) during the repolarization phase of the action potential. In voltage-clamp experiments background current has been observed to be strongly rate dependent: the background current during a test voltage-clamp pulse after a train of action potentials is more outward at higher stimulus frequencies. When the frequency is increased, background current slowly becomes more outward over several hundred seconds, and this change therefore occurs along the appropriate time course to explain the slow alteration in electrical activity under these conditions. The extra outward background current at high rates is relatively independent of membrane potential in the range from -110 to -40 mV (more circumstantial evidence indicates that this range may extend to at least +10 mV); this potential dependence is similar to that of the Na-K-pump current (Eisner & Lederer, 1980). Strophanthidin and ouabain, agents known to block the Na-K pump, alter both the changes in background current and the slow rate-dependent changes in electrical activity. Although after an increase in rate there is a gradual change in background current that can be explained by an increase in electrogenic Na-K-pump activity, the initial effect of switching rate is to produce a change in current that is consistent with an increase of the extracellular K concentration. A transient increase in the K concentration of restricted extracellular clefts has been recorded under these conditions in dog Purkinje strands by Kline & Kupersmith (1982) using K-sensitive microelectrodes. The effect on electrical activity of these changes is discussed.(ABSTRACT TRUNCATED AT 400 WORDS)

Bandwidth Enhancement of Monopole UWB Antenna With New Slots and EBG Structures (2013)

Two methods in terms of bandwidth broadening are proposed and compared for monopole slot ultrawideband (UWB) antennas supporting mobile terminal applications. The original antenna has a bandwidth of 9.27 GHz (1.73-11 GHz) that covers PCS1900, UMTS2000, TD-SCDMA, WLAN 802.11b/g or Bluetooth, LTE, WiMAX, and UWB frequency range. In this letter, by cutting two new slots on the ground plane, the antenna can expand its bandwidth to 9.33 GHz (1.67-11 GHz) that is available at extra DVB-H, DCS1800 services. Meanwhile, the bandwidth of the antenna with conventional mushroom-type electromagnetic band-gap (CMT-EBG) embedded on both sides of a 50- Ω microstrip line can be enhanced to 9.47 GHz (1.53-11 GHz) with the extra GPS covered. The largest impedance bandwidth of 151% can be obtained. Moreover, the comparisons of gain characters as well as the radiation patterns are discussed at the bands of interest. It is illustrated that the gain of the antenna based on CMT-EBG is higher than other two cases except to the range of 5.19-5.93 GHz and the radiation patterns are basically identical. The antennas are fabricated on FR4 substrate, and the deviations between measured results and simulated results are discussed.
Design, synthesis and pharmacological activities of 2-substituted 4-phenylquinolines as potential antidepressant drugs (1985)

This work represents the design, synthesis, and pharmacological testing of 4-phenylquinoline derivatives as potential antidepressants. Various modifications of substituents at the 2-position of the quinoline ring were tried, and two main series of derivatives were synthesized. In the first series, an open (dialkylamino)alkyl chain is linked to the 2-position of the quinoline ring by isosteres. The second approach involved the synthesis of a novel analogue of trazodone with a 4-phenylquinoline grouping replacing the chlorophenyl group of trazodone. The potential antidepressant activity of these new compounds has been demonstrated by their antagonism to the reserpine-induced hypothermia in mice. Both length of the side chain and isosteric displacements within the side chain affect the value of the ED50 obtained. Compounds having three atoms separating the terminal nitrogen from the quinoline ring were found to be more active than those with four atoms. The 2-thia derivatives were devoid of antidepressant activity. Replacement of the open side chain at the 2-position of the quinoline ring by piperazine or substituted piperazines resulted in new compounds that are slightly more potent than imipramine.
Isolation and Sequencing of a Plant cDNA Encoding a Bifunctional Methylenetetrahydrofolate Dehydrogenase : Methenyltetrahydrofolate Cyclohydrolase Protein (1999)

Summary In plant cells, the interconversion of formyl- and methylene-tetrahydrofolates is catalyzed by a bifunctional protein possessing methenyltetrallydrofolate cydohydrolase (EC 3.5.4.9) and methylenetetrahydrofolate dehydrogenase (EC 1.5.1.5) activities. The present work reports the isolation and sequencing of a cDNA that encodes this protein. Polydonal antibodies, raised against purified pea cytosolic dehydrogenase:cyclohydrolase, were used to screen a λgt 11 cDNA expression library, constructed from leaf extracts of this species. The screen identified a phage containing a cDNA insert with an open reading frame encoding a 294 amino acid protein (M r 31,344). The deduced primary structure of this protein contained most of the conserved regions found in other dehydrogenase:cyclohydrolase proteins including the corresponding domains of the trifunctional C 1 -THF synthases of mammalian and yeast origins.

Multiple path transport of information in wireless and wired networks (1998)

With the emergence of the World Wide Web and Multimedia, typical applications will need a higher bandwidth/higher reliability connection than that provided by current mobile networks. For supporting these applications a mobile node may need to set up and use multiple paths to the desired destination, either simply because of the lack of raw bandwidth on a single channel or because of its poor error characteristics, which reduces its effective throughput. Even in wired networks, applications may want to communicate using multiple paths to achieve stringent delay, loss or connection blocking probability requirements. The Multiple Path Transport (MPT) scheme satisfies this need by giving applications additional flexibility and control over the traffic distribution.
This work deals with some of the issues related with MPT, also referred to as diversity routing, a technique that splits traffic from a single connection among multiple paths. This makes the connection more robust, secure, and delivers higher end-to-end bandwidth, a set of advantages particularly valuable in a wireless network environment. The main disadvantage with MPT is the added complexity and resequencing delay. First we present some simple queueing and resequencing models, along with performance results that address the end-to-end delay (including the resequencing delay) issue for these simplified models. Subsequently, we discuss work on the protocols and algorithms needed to manage such connections.
For data applications, we consider MPT for bulk and interactive data transfer. With simple models and examples, we evaluate the delay-throughput performance of the MPT scheme and a session based routing scheme. We define the allocation granularity and investigate options of splitting traffic at various layers in the protocol stack.
We use MPT as a transport mechanism for transmission of video and image which employs Multiple Description Coding (MDC). We compare the performance of MPT when used in conjunction with an MDC coder and a Layered coder. Performance is evaluated in terms of Peak Signal to Noise Ratio (PSNR) and visual quality for video, image applications. When used in conjunction with MDC, MPT provides a more robust connection with higher bandwidth. An application can easily adapt its initial rate based on the total bandwidth available and, subsequently, based on the feedback from the end-system and intermediate routers and gateways.
Finally, we present some performance studies on a Fixed Wireless Local Loop (FWLL) system, a problem unrelated to the rest of this dissertation. With the help of simulations we evaluate the system's capacity which is defined, in this context, as the number of serviceable terminals per cell for a given percentage of terminals that exceed a preset Signal to Interference Ratio (SIR). The effect of various antenna parameters, correlation between shadow losses, and power control schemes on the system's capacity is also investigated.

Applicability of Dynamic Shear Rheometer to Measure Cement Paste Rheology for Identifying Cement–Admixture Incompatibilities (2008)

The complex interaction between cement and chemical / mineral admixtures in concrete mixture sometimes leads to unpredictable concrete performance in the field which is generally defined as concrete incompatibilities. Cement paste rheology measurements instead of traditional workability tests can have a great potential to detect those incompatibilities in concrete before the concrete is placed to avoid related workability problem and setting time and heat evolution abnormalities. The objective of the present study was to examine the applicability of Dynamic Shear Rheometer (DSR, originally designed to measure asphalt rheology) using Bingham model to measure cement paste rheology in one hand and identifying cement – admixtures incompatibilities based on the determined rheological parameters on the other hand. Rheological parameters were determined by modified DSR for both normal and incompatible mixtures using five different plate gaps. DSR with 1 mm plate gap is the most representative to distinguish the studied mixtures based on their rheology with best reproducibility and sensitivity. In order to validate the DSR as a standard rheometer, the DSR test results were verified by another advanced rheometer (AR 2000). The heat of hydration data from isothermal calorimeter test and setting time results for the studied mixtures have strongly supported the rheology based observations as supporting tools. Cement paste rheology measurement technique using the modified DSR has a great potential to identify cement - admixture incompatibilities. This will ultimately help material suppliers, concrete producers, and other users to detect problematic combination of concrete ingredients before the concrete is placed.
Differentiation between monoclonal antibody-defined antigens on a human osteogenic sarcoma cell line (791T) and tumor-localizing properties of the anti-791T/36 antibody. (1986)

Two monoclonal antibodies (anti-791T/36 and anti-791T/48) prepared against an osteogenic sarcoma cell line (791T) following xenogeneic immunization, reacted against the immunizing tumor, but not against normal cells from the tumor-donor, using an indirect 125I-protein A binding assay. Both antibodies cross-reacted with a small number of other osteogenic sarcomas and a few unrelated cell lines from an extensive panel, but the specificity of these cross-reactions was different. Both antibodies were labelled with 125I to detect direct binding to target cells, and the specificity of their reactivity was essentially identical to that observed in the indirect assay. Direct binding of each labelled antibody was inhibited by pretreating target cells with its unlabelled counterpart, but the two antibodies could not inhibit each other. The binding of anti-791T/36 was also not inhibited by pretreating the target cells with sera from the 791-T-tumor donor, which were shown to contain antibody reacting with the autochthonous tumor. It is concluded that 791T has two distinct tumor-associated antigens recognized by the monoclonal antibodies, and furthermore that at least one of these antigens is independent of those recognized by the patient from which the tumor cell line was derived. The efficacy of anti-791T/36 antibody labelled with radioactive iodine was demonstrated for localizing tumor deposits growing in immunodeprived mice.
