The determination of bond strength of polymeric films by indentation debonding (1988)

The underlying theory for determining the bond strength between a thin flexible film and a rigid substrate by means of a conical indenter has been reanalyzed. Graphs of normalized bond strength vs. ratio of the radii of the annular debonded area have been obtained whereby the former may be obtained from an experimental determination of the latter. Experimental results were obtained by indenting polyimide films of various thicknesses on a silicon substrate and for several curing temperatures. Numerical values of the bond strength were then found from the analysis.
Hypoxia-inducible Factor 1 Transactivates the Human Leptin Gene Promoter (2002)

Increased placental leptin has been demonstrated in preeclampsia, a pregnancy disorder associated with placental hypoxia. This suggests that leptin gene expression is enhanced in response to oxygen deficiency in this organ. In support of this hypothesis, we have previously shown that hypoxia activates the leptin promoter in trophoblast-derived BeWo cells. Hypoxia-inducible factor 1 (HIF-1) is a heterodimeric HIF-1alpha/HIF-1beta complex that regulates the transcription of hypoxia-responsive genes. To test whether this factor is involved in hypoxia-induced leptin promoter activation, BeWo cells were transiently transfected with a HIF-1alpha expression vector. Exogenous HIF-1alpha markedly increased luciferase reporter activity driven by the leptin promoter when HIF-1beta was co-expressed in the same cells. This effect was similar to that elicited by CoCl2, an agent known to stabilize endogenous HIF-1alpha. These data suggest that HIF-1alpha/HIF-1beta dimers are involved in the effect of CoCl2 to activate the leptin promoter. To confirm the implication of HIF-1, the cells were transfected with a dominant negative form of HIF-1alpha producing transcriptionally inactive HIF-1beta/HIF-1alpha dimers. This mutant HIF-1alpha protein abolished CoCl2 activation of the leptin promoter, providing direct evidence that the effect of CoCl2 is mediated by endogenous HIF-1alpha. Deletion analysis and site-specific mutagenesis demonstrated that a HIF-1 consensus binding site (HRE) spanning -120 to -116 bp relative to the start site was required for CoCl2 and exogenous HIF-1alpha induction of leptin promoter activity. Electrophoretic mobility shift assays performed with in vitro-translated HIF-1alpha and HIF-1beta proteins demonstrated binding to this HRE and not to mutated sequences only when both subunits were used together. These data demonstrate that leptin is a new hypoxia-inducible gene, which is stimulated in a placental cell line through HIF-1 interaction with a consensus HRE site located at -116 in the proximal promoter.
A Debugging Approach for Java Runtime Exceptions Based on Program Slicing and Stack Traces (2010)

Program debugging is an important process to improve the quality of software. Runtime exception can occur often and can be difficult to debug. In this paper, we present a new approach for locating faults that cause runtime exceptions in Java programs due to error assignment of a value that finally leads to the exception. Our approach first uses program slicing to reduce the search scope, then performs a backward data flow analysis, starting from the point where the exception occurred, and then uses stack trace information to guide the analysis to determine the source statement that is responsible for the runtime exception. The paper also presents a case study to demonstrate that the method is available. The approach not only resolves partly the imprecise of static techniques, but also reduces partly the heavy performance overhead of dynamic techniques.

Sketch interpretation in design communication (1999)

Designers need to communicate their ideas to others. But these ideas can be fluid, vague, provisional, and involve a mixture of degrees of detail and levels of abstraction. Expressing and interpreting imprecision and uncertainty is a challenge for human-computer interaction when designers use CAD systems. It is also a problem for communication between different members of design teams. Sketches are both a tool and a source of confusion for conveying provisionality and uncertainty. Freehand sketches are a fast and powerful medium for expressing design ideas; their inherent imprecision and ambiguity facilitates idea generation by allowing designers to see variations and re-interpret their own sketches. But misinterpretation of sketches is a major cause of communication failure in design teams. This paper presents an analysis of imprecision in sketch-based communication. It is intended as a foundation for technological and organisational approaches to improving communication in design teams.
A phase II trial with rosiglitazone in liposarcoma patients (2003)

Agents of the thiazolidinedione drug family can terminally differentiate human liposarcoma cells in vitro by activating genes responsible for lipocyte differentiation. One study has shown clinical activity of troglitazone treatment in liposarcoma patients. We sought to find further evidence for this result. In all, 12 patients with a liposarcoma received rosiglitazone 4 mg b.d. They were followed clinically and with repeated biopsies for histological and biological studies. At the molecular level the mRNA translation of three genes that are induced by this treatment (peroxisome proliferator-activated receptor gamma (PPARgamma), adipsin and fatty acid binding protein) was determined. Nine patients were eligible for evaluation. One patient had to stop treatment due to hepatotoxicity. The mean time to progression was 6 months (2 - 16 months), with one patient still on treatment. We did not see any significant change in histologic appearance of the liposarcomas by the treatment. The level of gene expression changed significantly in two patients, but this did not result in a clinical response. Based on this study, rosiglitazone is not effective as an antitumoral drug in the treatment of liposarcomas. Increased PPARgamma activity does not correlate with the clinical evolution.
Simulation recurrence of a realistic DC line fault based on RTDS and its simulation reliability analysis (2009)

In this paper, the equivalent model of a local HVDC transmission system is set up based on Real-Time Digital Simulator (RTDS). A realistic DC line fault on the pole 2 of the HVDC project is simulated successfully by use of the RTDS model connected with actual physical control and protection devices. And then, a complete evaluation theory of simulation errors is proposed. In the theory, residuals similarity is used to characterize the global error of dynamic simulation, and frequency, damping and amplitude similarity are used to characterize features errors respectively. The comparison analysis has been carried out between the simulation results and the fault recordings by the simulation similarity computation procedure based on LabVIEW. It is proved that the simulation results of existing models are almost the same as the fault recordings, and the simulation model of HVDC transmission system established can reflect operation characteristics of real network exactly. The realistic faults can be reproduced by the simulation experiment accurately.
On the overmodulation limit in externally modulated lightwave AM-VSB CATV systems (1996)

The overmodulation limit in an externally modulated system is more severe than in a directly modulated laser system. The RMS modulation depth is determined to be no more than 0.238 for an externally modulated system.
IEEE 2004 CUSTOM INTEGRATED CIRCUITS CONFERENCE A 10Gb/s Data-Dependent Jitter Equalizer (2015)

An equalization circuit is presented that reduces data-dependent jitter by aligning data transition deviations. This paper presents an analytic solution to data-dependent jitter and demonstrates its impact on the phase noise of the recovered clock. A data-depen-dent jitter equalizer is presented that compensates the impairment of the channel and lowers the phase noise of the recovered clock. The circuit is implemented in a SiGe BiCMOS process and oper-ates at lOGb/s. It suppresses phase noise resulting from data-dependent jitter by 10 &amp;.
Randomized controlled trial of modafinil for the treatment of fatigue in postpolio patients (2005)

The purpose of this study was to test whether modafinil is effective in alleviating the symptoms of fatigue in postpolio patients, because it has been helpful for such symptoms in other neurologic disorders. Using a double-blind, randomized, placebo-controlled cross-over design, 14 postpolio patients with moderate to severe fatigue were assigned to receive modafinil or placebo first. Piper Fatigue Scale, Epworth Sleepiness Scale, digit span, and reaction time tests were done at baseline and then at weekly intervals. The Piper Fatigue Scale scores improved by 27 +/- 40% (mean +/- SD) following modafinil and by 43 +/- 36% following placebo. Scores for most of the other tests did not change during the study. Therefore, we conclude that modafinil was not effective in alleviating the symptoms of fatigue in postpolio patients.
Pulsed‐field gel electrophoresis to study the diversity of whole‐genome organization in the genus <b><i>Ochrobactrum</i></b> (2005)

The alpha-proteobacterial genus Ochrobactrum groups together organisms that display varied life-styles, such as free-living bacteria, members of rhizosphere and soil, nitrogen-fixing bacteria in plant nodules, xenobiotic-degrading bacteria, colonizers of nematodes and insects, and opportunistic human pathogens. The genomes of nine strains of Ochrobactrum anthropi and eight strains of Ochrobactrum intermedium were analyzed by pulsed-field gel electrophoresis of the whole genome and of I-CeuI digestion fragments. All isolates and type strains of O. anthropi and O. intermedium possessed two high-molecular-weight circular replicons identified as two independent chromosomes on the basis of 16S rDNA hybridization. The genome of the type strain of Ochrobactrum tritici, Ochrobactrum grignonense, and Ochrobactrum gallinifaecis also contained two circular chromosomes. The megaplasmid content was highly variable even among strains in the same species, leading to whole-genome sizes that ranged from 5.060 to 8.300 Mbp and from 4.690 to 7.680 Mbp for O. anthropi and O. intermedium, respectively. This exceptional level of genomic diversity could be related to the adaptability of Ochrobactrum spp. to various ecological niches.
Microinjection of sulpiride into the nucleus accumbens increases ethanol drinking in alcohol-preferring (P) rats. (1991)

The effects of dopamine antagonists microinjected into the nucleus accumbens (Acb) on alcohol-drinking behavior were studied in the selectively bred alcohol-preferring (P) line of rats. P female rats (N = 8) were given access to food and water ad lib, while availability of a 10% (v/v) ethanol solution was limited to 1 hr/day. After implantation of guide cannulas bilaterally into the Acb and recovery from surgery, the rats were microinjected with either the D1 antagonist SCH 23390 (0.1 to 2.0 micrograms/side), the D2 antagonist sulpiride (0.1 to 2.0 micrograms/side) or vehicle, and ethanol intake was monitored. The D1 antagonist SCH 23390 had little effect on alcohol intake although the 0.5 ug/side dose produced a small increase which was not statistically significant. The D2 antagonist sulpiride increased, in a dose dependent manner, the intake of ethanol to as high as 215% of control values (F(4,28) = 39.9; p < 0.001). Additional experiments indicated that the 2.0 micrograms/side dose of sulpiride did not alter the consumption of a 14% glucose nor a 0.25% saccharin solution. These data suggest that D2 receptors in the Acb are important in the regulation of alcohol drinking by the P line of rats.

Analytical evaluation of radiation patterns of a TACAN antenna (2003)

The authors present a method for the analytical evaluation of the radiation patterns of a TACAN (tactical air navigation) antenna, based on image theory. The discone antenna utilized in TACAN gives an omni pattern in the horizontal plane. A single lobe caused by the inner parasitic and nine lobes arising due to the outer parasitics together effectively enable coarse and fine bearing measurements. Since the inner and outer parasitics are both rotated at 15 rev/s, the nine-lobed pattern rotates in space at a 15-Hz rate.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Adapting the infrastructure provided by the World Wide Web for educational purposes (2002)

The World Wide Web provides a rich infrastructure for multimedia communication that is increasingly being exploited in the service of education. To date, this infrastructure has primarily been used for the delivery of course materials to students. Increasingly, however, attempts are being made to extend the functionality provided by the WWW to include support for all aspects of the learning process. This paper describes how extensions to the World Wide Web can be used to develop individual learning support tools which can then be combined to provide a suitable learning support environment for a particular educational task. Two approaches to the design of a web aware tool to support and capture electronic, multimedia dialogue about course material are described. The first is centered on the use of the Common Gateway Interface, the second on the use of Java. The relative merits of each approach are discussed and an example of a tool implemented by each method, the AnswerWeb and Organik, described.
Prostaglandin F-2α causes regression of an hCG-induced corpus luteum before Day 5 of its lifespan in cattle (1990)

The experimental objective was to evaluate how a spontaneously formed corpus luteum (CL) differed in its response to prostaglandin (PG) F-2 alpha, given during the first 5 days after ovulation, from a CL induced during dioestrus with hCG. Sixteen Holstein heifers were used during each of 2 consecutive oestrous cycles. During the first cycle (sham cycle), heifers were given no PGF-2 alpha (control) or PGF-2 alpha (25 mg, i.m.) on Day 2, 4 or 6 (oestrus = Day 0). During the second cycle (hCG-treated cycle), heifers were given hCG (5000 i.u., i.m.) on Day 10, followed by no PGF-2 alpha (control) or PGF-2 alpha on Day 12, 14 or 16, corresponding to 2, 4 or 6 days after the ovulatory dose of hCG. A new ovulation was induced in 13 of 16 heifers given hCG on Day 10. Luteolysis did not occur immediately in heifers given PGF-2 alpha on Day 2 or 4 during the sham cycle, but concentration of progesterone in serum during the remainder of the cycle was lower in heifers given PGF-2 alpha on Day 4 than in sham controls or heifers given PGF-2 alpha on Day 2 (P less than 0.05). Luteolysis occurred immediately in heifers given PGF-2 alpha on Day 6 of the sham cycle or on Day 12, 14 or 16 of the hCG-treated cycle, with concentration of progesterone in serum decreasing to less than 1 ng/ml within 2 days.(ABSTRACT TRUNCATED AT 250 WORDS)
Cystic Fibrosis Transmembrane Conductance Regulator-associated ATP and Adenosine 3′-Phosphate 5′-Phosphosulfate Channels in Endoplasmic Reticulum and Plasma Membranes (1997)

Cystic fibrosis (CF) is characterized by abnormal regulation of epithelial ion and fluid transport due to mutations in the CF transmembrane conductance regulator (CFTR), an apical membrane-localized Cl- channel, that usually prevent it from exiting the endoplasmic reticulum. Defective or absent CFTR in the epithelium is believed to disrupt fluid balance in human airways and thereby contribute to chronic respiratory inflammation. Patch-clamp of the plasma membrane and outer membrane of the nuclear envelope of nuclei isolated from CFTR-expressing Chinese hamster ovary cells revealed that CFTR is associated with a regulated ATP channel in both membrane compartments. CFTR expression was also shown to be associated with permeability to another adenine nucleotide, adenosine 3'-phosphate 5'-phosphosulfate, the universal sulfate donor in cells. These results may provide a link between the ion channel function of CFTR and abnormal glycoprotein processing observed in CF.
Study On Potential Utilization Of Sugarcane Bagasse Ash In Steel Fiber Reinforced Concrete (2016)

Aim of the project is to utilize the waste product produced by agricultural industry and enhancement of concrete strength by using steel fiber. Sugarcane bagasse ash (SCBA) is a left-over industrial byproduct which is used as a replacement of cement. SCBA has high content in silica. Using of SCBA in concrete is a remarkable possibility for economy and conservation of natural resources. One of the important properties of steel fiber reinforced concrete (SFRC) is its superior resistance to cracking and crack propagation. As a result of this ability to arrest cracks, fibers are able to hold the matrix together even after extensive cracking. In this project SCBA has been partially replaced with cement in the ratio of 0%, 5%, 10%, 15% and 20% by the weight of cement in M30 Grade concrete. From the test results optimum percentage of SCBA has achieved on steel fiber reinforced concrete.
The Effect of Beta Adrenergic Blocking Drugs on Speakers' Performance and Memory (1983)

Propranolol 40 mg was compared with a matched placebo tablet in its effect on the performance of anxious and non-anxious human volunteers. Subjects were required to give a brief speech, which was video-taped and later rated by trained observers for signs of anxiety; propranolol clearly reduced rated anxiety in the non-verbal behaviour of anxious subjects, as well as the anxiety observed in the speech of the anxious compared to the non-anxious. It also affected self-reported anxiety in the anxious, and reduced the pulse rate of anxious and non-anxious alike. Subjects were also prompted, by being given the first letter, to recall both difficult and easy words, drawn from selected verbal categories; propranolol impaired recall of difficult items in the memory of anxious subjects. Results were interpreted as showing a central as well as peripheral role for propranolol in blocking adrenergic receptors' activity in anxiety.
Synthesis and Surface Modification of Calcium Carbonate Nanoparticles Using Ultrasound Cavitation Technique (2015)

Calcium carbonate nanoparticles (nCaCO<sub>3</sub>) was synthesized using optimized process of ultrasound assisted precipitation technique. Due to ultra-sonication phenomena, reacting components of reaction mixture gets dispersed uniformly, and at the same time nCaCO<sub>3</sub> particles agglomerate with each other due to strong electrostatic force of attraction developed over their surface. The de-agglomeration and charge nullification were achieved using surface modification of CaCO<sub>3</sub> nanoparticles using triethoxy vinyl silane (TEVS) under ultrasound environment. The surface modification of nCaCO<sub>3</sub> particles was confirmed using Fourier transforms infrared (FTIR) spectroscopy. Size, shape and formation of nCaCO<sub>3</sub> particles at nanoscale were studied using transmission electron microscopy (TEM). The size of unmodified and modified nCaCO<sub>3</sub> was found to be ≈50-80 and 50-90 nm, respectively, with square crystal structure morphology. Due to the surface modification by TEVS, thin layer was formed over the surface of nCaCO<sub>3</sub> particle, which was confirmed by TEM micrograph. The purpose behind carry out this reaction under ultrasound environment is to optimize synthesis procedure of nCaCO<sub>3</sub> particles, to provide effective ultrafine precipitation and give stable & uniform dispersion of inorganic particles with reactants. Moreover, the acoustic waves of ultrasound treatment are an effective controlling parameter to obtain uniform dispersion of inorganic nanoparticles in solution by producing non-linear effects in reaction mixture. In this ultrasound treatment, transient cavitation and acoustic stretching are the most dominant affecting parameters, which give homogeneous dispersion of nCaCO<sub>3</sub>.
