The cellulose–butadiene diepoxide reaction and its effect on the crease resistance of cotton (1961)

Abstract Butadiene diepoxide (BDE), the meso ‐1,2,3,4‐diepoxybutane, may be added to cotton cellulose with a variety of catalysts and conditions at room temperature. A slow addition of BDE from nonpolar solvents to yarns pretreated with alkali resulted in weight gains which were proportional to the activity of hydroxyl ions used in pretreatment. For a given hydroxyl ion activity, percentage weight gains of BDE varied directly with time of reaction. Add‐on of BDE has been shown to be proportional to the product of hydrolyzed BDE and molarity of the hydroxyl ion in the dilute alkali. It has been shown that slow addition of epoxide from carbon tetrachloride solution to cotton fabric impregnated with dilute alkali, natural salts, or alkaline salt solutions produces a fabric of good dry and wet crease recovery. Rapid addition of epoxide to fabric by the use of more concentrated alkali or elevated temperature showed excellent wet, but no dry, crease recovery. Hydrogen ion catalysis of the BDE–cotton reaction is very slow and, in the case of acetic acid, is without effect. With sulfuric acid, only mediocre wet crease recovery is produced a t room temperature. Catalysis with zinc fluoborate, methanolic solutions of BDE, and curing temperatures of 75–125° resulted in excellent wet and dry crease resistance a t weight gains of less than 2%. All methods of BDE addition to cotton fabric that produce good dry crease recovery cause a lowering of tearing and breaking strengths. There is little change in tensile properties when only wet. crease resistance is imparted. This suggests that profound physical changes in the fine structure of cellulose result from mild chemical action with a water‐soluble diepoxide. Recovery from deformation of cotton fibers in the wet and dry states (crease recovery) has been attributed to intermolecular covalent crosslinking of anhydroglucose unit hydroxyls by the diepoxide and, in particular, to crosslinking of hydroxyls on carbons 2 or 6, with a resultant diminution of interchain slippage. Fibers that exhibit only wet crease recovery are believed to have a minimum of covalent crosslinks and to be hydroxy cellulose monoethers of the epoxide or graft polymers of the same, which prevent slippage of chains only when wet and swollen (possibly by entanglement).
A thermodynamic and N.M.R. study of the ribbon lyotropic mesophases. An investigation of the potassium palmitate/potassium laurate/water system (1989)

Abstract Lyotropic ternary mixtures of K-palmitate/K-laurate/water with different compositions have been investigated by 2H N.M.R., differential scanning calorimetry and thermo-volumetric analysis. The transitions between rectangular ribbon-like aggregates and lamellar structures have been characterized and explained on the basis of a theoretical model. Our results suggest that for ternary systems containing a small amount of short chain lipids the ribbon structure is more stable at low temperature. Moreover, the rectangular shape is favoured both by the segregation of the short chain lipids at the curved edges of the ribbon and by a tighter packing of the hydrocarbon chains in the same region.
High speed 1.3µm InGaAsP Buried Crescent Injection Lasers With Semi-Insulating Current Confinement Layer (1987)

A hybrid growth technique has been used to fabricate high modulation bandwidth 1.3 µm InGaAsP buried crescent (BC) injection lasers. The technique involves a first growth of an Fe-doped semi-insulating (SI) InP current confinement layer by low pressure metal organic chemical vapor deposition (LPMOCVD) followed by a liquid phase epitaxy (LPE) regrowth. The lasers have room temperature threshold currents and differential quantum efficiencies ranging from 20 to 30 mA and 0.2 to 0.3 mW/mA/facet, respectively. A 3-dB modulation bandwidth of 5 GHz has been achieved.
[Treatment of Candida urinary tract infections with reference to serum levels of anti-Candida antibody and D-arabinitol]. (1987)

A clinical study was carried out on 11 patients with Candida urinary tract infection; 4 with chronic cystitis and 7 with acute pyelonephritis including 2 patients associated with candidemia. The patients received 1.5 to 6.0 g of 5-fluorocytosine (5-FC) orally daily for 6 to 22 days. The response was excellent in 6, moderate in 4 and poor in 1 case, overall efficacy rate being 90.9%. No patients showed any adverse reaction. The antibody against the Candida species was measured by an indirect hemagglutination test and the serum level of D-arabinitol, a major metabolite of Candida species, was determined by gas-liquid chromatography. A 4-fold or greater rise in anti-Candida antibody was detected in 4 of the 6 patients with pyelonephritis, including one patient associated with candidemia, 14 to 31 days following the treatment. Serum D-arabinitol levels in all of the 4 patients with pyelonephritis exceeded the detection limit of 0.2 microgram/ml before treatment. The levels decreased promptly during treatment and normalized 10 to 20 days after the start of treatment. These results suggest that 5-FC is an effective drug for Candida urinary tract infections. The determinations of anti-Candida antibody titer and serum D-arabinitol level may be clinically useful for the diagnosis of Candida pyelonephritis. In particular, the serum levels of D-arabinitol appear to be a useful parameter to follow-up the effect of anti-fungal treatment on Candida pyelonephritis.
IMMUNOTHERAPY OF OSTEOSARCOMA PATIENTS WITH VIRUS‐MODIFIED TUMOR CELLS* (1976)

Twelve patients 11-20 years of age with recurrent osteosarcoma were immunized with either autologous or allogeneic tumor cells infected with influenza virus, strain B/Michigan or A/Port Chalmers. Six patients received only the vaccine, and the remaining six patients continued to receive methotrexate chemotherapy. The main objectives of this study were to determine if immunizations were toxic, if antibodies developed to the influenza virus antigen component of the vaccine, if this vaccine increased tumor-specific cellular and humoral immunity, and if the increase in immune response could be correlated with clinical course and prognosis. In all 12 cases, toxicity was negligible, and immunizations boosted antibody titers to both tumor cell and influenza virus antigens. However, in four of the six patients with advanced disease who received immunotherapy only, the vaccine did not stimulate mixed lymphocytes nor did it increase cell-mediated immunity. By contrast, five of six patients with minimal disease who continued methotrexate therapy developed cellular and humoral immunity in response to both allogeneic and autologous tumor cells. Although no clear-cut relationship between responses to the tumor cell vaccine and clinical course and prognosis could be demonstrated, three of the six patients with minimal disease have survived for 7-8 months after the first vaccination, without progression of disease. This study demonstrates that plasma membrane preparations derived from different lines of virus-infected osteosarcoma tumor cells will elicit an antibody response in patients with drug-resistant progressive osteogenic sarcoma.

The Metabolic Response of Heterotrophic Arabidopsis Cells to Oxidative Stress (2006)

To cope with oxidative stress, the metabolic network of plant cells must be reconfigured either to bypass damaged enzymes or to support adaptive responses. To characterize the dynamics of metabolic change during oxidative stress, heterotrophic Arabidopsis (Arabidopsis thaliana) cells were treated with menadione and changes in metabolite abundance and (13)C-labeling kinetics were quantified in a time series of samples taken over a 6 h period. Oxidative stress had a profound effect on the central metabolic pathways with extensive metabolic inhibition radiating from the tricarboxylic acid cycle and including large sectors of amino acid metabolism. Sequential accumulation of metabolites in specific pathways indicated a subsequent backing up of glycolysis and a diversion of carbon into the oxidative pentose phosphate pathway. Microarray analysis revealed a coordinated transcriptomic response that represents an emergency coping strategy allowing the cell to survive the metabolic hiatus. Rather than attempt to replace inhibited enzymes, transcripts encoding these enzymes are in fact down-regulated while an antioxidant defense response is mounted. In addition, a major switch from anabolic to catabolic metabolism is signaled. Metabolism is also reconfigured to bypass damaged steps (e.g. induction of an external NADH dehydrogenase of the mitochondrial respiratory chain). The overall metabolic response of Arabidopsis cells to oxidative stress is remarkably similar to the superoxide and hydrogen peroxide stimulons of bacteria and yeast (Saccharomyces cerevisiae), suggesting that the stress regulatory and signaling pathways of plants and microbes may share common elements.
Studies of Diarylalkanes. III. The Cleavage of Diarylmethanes under the Influence of Aluminum Chloride (1965)

Abstract The reaction of several diarylmethanes (III –XII) with aluminum chloride under various conditions has been carried out in order to elucidate the effect of the substituent on the cleavage of diarylmethanes. It has been established that the bond between the aromatic ring and the methylene group is cleft and that the cleavage is affected by the relative basicities of the two aromatic rings in the diarylmethane as well as by the basic strength of the benzene derivative which is present in the reaction system.
ISDN U transceiver algorithm, development system, and performance (2003)

Motorola and BNR are currently developing the MC145472, a single-chip implementation of a 2B1Q ANSI standard U-interface transceiver for ISDN (integrated services digital network) basic rate access (BRA). The transceiver provides full duplex transmission of 160 kb/s over two-wire nonloaded outside plant loops and is designed to meet the ANSI T1.601 1988 standards for use in both LT and NT1 applications. Its implementation involves state-of-the-art analog and digital signal processing (DSP) technology. The authors describe the functions and verifications of the transceiver, with emphasis on the DSP technology used for echo cancellation, equalization, and timing recovery; the design methodology and hardware testbed used to develop the transceiver algorithms; and performance results for the transceiver under both laboratory and field conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
K-ras transformation greatly increases the toxin-dependent ADP-ribosylation of GTP binding proteins in thyroid cells. Involvement of an inhibitor of the ADP-ribosylation reaction. (1992)

The GTP binding (G) proteins of normal (FRTL5) and ras-transformed thyroid cells (KiKi) were characterized by cholera and pertussis toxin-induced ADP-ribosylation and immunoblot analysis. Two pertussis toxin substrates with molecular masses of 40 and 41 kDa were identified in normal cells as the alpha i2 and alpha i3 subunits. The molecular masses of the cholera toxin substrates were 42 and 45 kDa. The same cholera and pertussis toxin substrates were present in the K-ras-transformed cell line. However, the toxin-dependent ADP-ribosylation was markedly higher in KiKi than in normal cell membranes (more than 50-fold). The reason for this difference was investigated; it could not be explained by the relative amounts of G proteins in the two cell systems, since the levels of alpha i2 subunit as measured by quantitative immunoblot in K-ras-transformed cells were only slightly (65%) higher than in normal cells. The difference in ADP-ribosylation was not due to poly-ADP-ribosylation nor to a different degree of subunit dissociation of G proteins in the two cell lines. Rather, the enhanced ADP-ribosylation in K-ras-transformed cells appears to be due to the loss of an inhibitory factor present in the normal cells. Partial characterization indicates that such a factor is a peripheral membrane protein of less than 25 kDa capable of directly interfering with the ADP-ribosylation reaction.

Weed Control and Plant Residue Maintenance with Various Tillage Treatments in a Winter Wheat‐Fallow Rotation<sup>1</sup> (1969)

Abstract Late spring tillage gave the most effective weed control in a winter wheat ( Triticum aestivum L.)‐fallow rotation. Downy brome ( Bromus tectorum L.) populations in winter wheat on May 1 following plow, one‐way, and sweep plow fallow treatments were 11, 22, and 24 plants per square meter, respectively. Tillages only in July or August with the sweep plow or one‐way did not effectively control downy brome in the subsequent wheat crop. Yields of winter wheat were highest on the mold‐board plow plots followed by one‐way and sweep plow plots tilled in July and again in April. July tillages with the sweep plow or one‐way resulted in the lowest winter wheat yields. During the fallow year, weed control in June was best on moldboard‐plowed plots followed by May tillages with the sweep plow and the one‐way. Quantities of plant residues on the soil surface prior to seeding winter wheat on sweep plow, one‐way, and plot treatments were 896, 728, and 54 kg/ha, respectively.
Efficient RF Coverage Prediction through a fully Discrete, GPU-Parallelized Ray-Launching model (2018)

A fully discrete Ray Launching field prediction algorithm that takes advantage of environment visibility preprocessing for both diffuse and specular interactions is presented and used to perform efficient RF coverage prediction in large environments. The algorithm, being discrete, has been parallelized in a straightforward way on NVIDIA-compatible Graphical Processing Units. These innovative features combined allow to achieve a computation time reduction of about three orders of magnitude compared to conventional algorithms, while retaining the same accuracy level.
TRACK COMPONENT--PROPERTY TESTS VOLUME I--RAIL, TIE AND FASTENERS (1979)

This report describes the test procedures and the results of tests on the physical properties of rail, tie and fastener. The properties obtained are the bending rigidity of the tie, bending rigidity of the rail in both the vertical and lateral planes, and the fastener resistance to rotation about the vertical axis. The component tests were run on two rail sections, 115 lb RE and 136 lb RE, on 7x9x81/2 gum ties and on three fastener configurations on the two different rail sections. The tests were conducted at the Association of American Railroads (AAR) Track Structures Dynamic Test Facility in Chicago, Illinois.
Transcranial Doppler in Asymptomatic Carotid Stenosis Representing Hemodynamic Impairment: Correlation Study with Magnetic Resonance Imaging (2004)

ABSTRACT Background and Purpose . Since the benefit of an endarter ectomy in an asymptomatic carotid stenosis is not as clear as that in symptomatic stenosis, identifying patients with a high risk of stroke will allow the improved selection of surgical candidates. To evaluate the role of transcranial Doppler (TCD) in assessing an asymptomatic stenosis, this study examined the association of a TCD‐detected hemodynamic change with a stenosis‐related abnormality on magnetic resonance imaging (MRI). Methods . Asymptomatic patients with a more than 60% internal carotid artery stenosis were enrolled in this study. The hemodynamic change in the TCD was analyzed in terms of the demographic characteristics, the stroke risk factors, and the stenosis‐related MRI abnormalities that are a proven risk factor of a further stroke. Results . Fifty‐three patients were retrospectively recruited. While there were no differences in the demo graphic characteristics or frequency of the stroke risk factors, the proportion of patients with stenosis‐related MRI abnormality was significantly higher in patients with a hemodynamic change on TCD (13/19 vs 6/34, P < .01; odds ratio = 10.11; 95% confidence interval = 2.73–37.4). Conclusions . The TCD‐detected hemodynamic changes may provide useful information for assessing the frequency of silent stroke in patients with an asymptomatic carotid stenosis.
Augmented −1 adaptive control of an actuated knee joint exoskeleton: From design to real-time experiments (2016)

This paper deals with the control of a lower limb exoskeleton acting at the knee joint level. Classical −1 adaptive control law is proposed to ensure assistance-as-needed and resistive rehabilitation following a desired trajectory that is defined by a therapeutic doctor. This control law introduces a time lag within the desired trajectory tracking due to the presence of a filter in its structure. In order to mitigate this drawback, the classical −1 adaptive control is augmented by a nonlinear proportional control. The classical and augmented −1 adaptive control laws are tested in real-time using the Exoskeleton Intelligently COmmunicating and Sensitive to Intention (EICOSI) of LISSI-lab. Real-time experimental results highlight the utility of these control laws in assistance-as-needed and resistive rehabilitation paradigms.
Knowledge Discovery in Plastic Cards Transactions by Using Data Mining (2012)

Today with swift growing of plastic cards industry in the world, variety and volume of data stored in the database is growing strongly, this issue reminds the growing need of banks and financial institutions in applying knowledge discovery processes on value creation services. The original approach of this paper, is step by step implementing process of data mining in real-life transaction of debit cards, with the aim of customer profiling. In this study profiling is applied with two approaches of explorative and predictive analysis. In explorative model SOM and TwoStep clustering techniques are used. Also in predictive model four decision tree techniques are applied, the C5.0, Chi-square Automatics Interaction Detection (CHAID), Quest, classification and regression. Finally, the optimal models details are more analyzed to discover the knowledge in transactions done.
A simulation of synthetic range profile radar (2003)

Synthetic range profiling is a technique where high range resolution is obtained by transmitting a series of pulses at different frequencies, and then using signal processing to form a high resolution image of target reflectivity along the range axis. The technique is basically an extension of pulse compression theory. This paper summarises the theory and describes a simulation system used to determine whether existing radars are suitable for synthetic range profiling. A discussion on the interpretation of range profiles is included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Treatment of multiple sclerosis with interferon beta 1b. (1997)

Interferon beta 1b is now an established therapeutic option for relapsing remitting multiple sclerosis. More recently, it has also been shown to slow down disease progression in secondary progressive multiple sclerosis. Interferon beta 1b's clinical effect is reflected in MRI studies demonstrating a dramatic effect in reducing disease activity. The drug is generally well tolerated, but its efficacy can be compromised in some patients by the emergence of neutralizing antibodies. This chapter will focus on interferon beta 1b (Betaseron) treatment for multiple sclerosis, its clinical and MRI effects, and its putative mechanism of action.
Device for in-vivo study of the tumor micro-environment (2010)

In-vivo cancer cells create a unique microenvironment which enables their spread to other organs. To understand the tumor microenvironment, special tools and devices are required to monitor the interaction among different cell types as well as the effects of particular chemical gradients. We are reporting on the status of a new device (the NANIVID: NANoIntraVItal Device) that will collect chemotactic cells from the tumor environment. Due to the transparency of this implantable device, direct in-vivo cell imaging both inside and outside the device is possible. The cell collection chamber of the device consists of a micro-electrode system based on patterning of transparent, conducting films that deliver real time data including cell density and dynamics. The current development and testing status of the device will be presented. This will include the modeling of ligand gradient profile results produced from the device and the cell migration in the EGF (epidermal growth factor) gradient created by the device. Further, prototype electrode arrays were designed, fabricated and cells were cultured on the arrays at selected degrees of confluence to measure the device sensitivity. The development path of the NANIVID will be integrated with an existing animal model protocol for in-vivo testing. This will result in a clearer understanding of the dynamics of a tumor's metastatic progression.
