Experimental Study on Wall Transmission Loss of Electric wave for the RTLS Application of Building Construction Project (2009)

Although the concept of RTLS is very unfamiliar to construction industry, recently it is popular in other industry, such as logistics, ship building, mobile telecommunication based on state-of-the-art information technology. Effective resource management using cutting-edge information technology makes it possible to succeed a project with saving the time and cost. And effective information management in construction project can be achieved by the new technologies such as RFID, WEB-based internet, DB technology, real-time monitoring technology, etc. This paper suggest the characteristics and applicability of the international standard electric waves to be used for the real-time locating system (RTLS) on the viewpoint of transmission loss in construction field to monitor and manage resources of construction project effectively The two types of electric waves based on the international standard is to be suggested after surveying the as-is technology in the related industries and then is analyzed to find out the characteristics of those by the concept of the electric wave transition loss in the several construction situations. Two main electric waves, the 2.4GHz and the 433MHz technologies as the international standard is researched on the applicability to the indoor environment of construction site.
Mapping of cat albumin using monoclonal antibodies: identification of determinants common to cat and dog. (1989)

Cat and dog albumins from commercial extracts were used to produce monoclonal antibodies (MoAb). Anti-cat albumin MoAb recognized both cat and dog albumin equally, as did anti-dog albumin MoAb; this confirms cross-reactivity between cat and dog. The MoAb were separated into two groups according to their epitopic specificity; they recognized two overlapping epitopes of cat albumin. Furthermore, by competitive inhibition of radio-allergosorbent test (RAST), it was shown that one MoAb group inhibited significantly the binding of human IgE antibodies (from a pool of 13 patients allergic to both cats and dogs) to insolubilized cat or dog extracts. These observations suggest that murine anti-cat or anti-dog MoAb and human IgE antibodies recognize identical or closely related determinants on cat and dog albumin.
Energy distribution analysis and nonlinear dynamical analysis of phonation in patients with Parkinson's disease (2017)

Patients with Parkinson's disease (PD) have been reported to exhibit vocal impairment during the course of PD. Recently, development of automatic PD severity assessment based on acoustical characteristics from voice recordings has been attempted. However, objective extraction of appropriate features that can characterize PD symptoms faces many problems, due to the prevalence of aperiodicity in PD voices, rendering traditional perturbation analysis unreliable. The present study attempted to examine the validity of more advanced acoustic analysis techniques based on energy distribution measures and nonlinear dynamical measures. All of the features were extracted from sustained phonations of the vowel /a/ produced by 16 PD patients and 20 age-matched non- pathologic subjects. Results revealed that the energy distribution measures, such as glottal-to-noise excitation (GNE), and empirical mode decomposition excitation ratio (EMD-ER), as well as nonlinear dynamical measures including correlation dimension (D2), permutation entropy (PE), and detrended fluctuation analysis (DFA) were effective in discerning between PD and normal voices. This finding suggests that both energy distribution and nonlinear dynamical analyses could be appropriate measures in determining the status of PD voice.
Thermal Analysis of Concentrated Photovoltaic System (2010)

Studying the thermal process of concentrating system could help us better understand how photovoltaic system works and seek ways to increase electricity production so as to reduce the cost of power generation. Energy transfer of concentrating photovoltaic system includes the process of light to electricity and the process of direct current to alternating current. This paper presents the factors that affect the energy transfer efficiency of the former one. And at last author points out that the key factor to increase the power production of photovoltaic system is controlling the temperatu- re of solar cell.
Effect of Temperature on Ductility of Annealed 6.5% Si-Fe Hotrolled Alloy (2002)

The tensile property of annealed 6.5% Si\|Fe hot\|rolled alloy has been investigated at different temperatures.The microstructure was examinated by optical microscope.Fracture surface of the tensiled specimen was examinated by SEM.It was found that the layer structure of the hot\|rolled alloy was eliminated after annealing at 750℃ for 140mins.And with the increasing of temperature,fracture mode varied significantly from cleavage fracture to ductile fracture.At 200℃,the fracture mode was cleavage,and the elongation of the alloy reached 26%.But as the temperatures ranged from 200℃ to 400℃,the elongation didn′t increase rapidly with the increasing of the temperature,and the fracture mode was the mixture of cleavage and dimple.At 500℃ the largest elongation reached 43%,and the fracture mode was complete dimple.
Field-Sequential Electronic Stereoscopic Projector (1989)

Culminating a research and development project spanning many years, StereoGraphics Corporation has succeeded in bringing to market the first field-sequential electronic stereoscopic projector. The product is based on a modification of Electrohome and Barco projectors. Our design goal was to produce a projector capable of displaying an image on a six-foot (or larger) diagonal screen for an audience of 50 or 60 people, or for an individual using a simulator. A second goal was to produce an image that required only passive polarizing glasses rather than powered, tethered visors. Two major design challenges posed themselves. First, it was necessary to create an electro-optical modulator which could switch the characteristic of polarized light at field rate, and second, it was necessary to produce a bright green CRT with short persistence to prevent crosstalk between left and right fields. To solve the first problem, development was undertaken to produce the required electro-optical modulator. The second problem was solved with the help of a vendor specializing in high performance CRT's.
Postmortem Forensic Toxicology of Trazodone (2000)

Trazodone is a popular antidepressant medication that has been available for approximately 30 years. It has a reputation as a safe drug with relatively few reported fatalities attributed solely to it. We review the pharmacology and forensic toxicology of trazodone and report toxicology and cause and manner of death in a series of 37 deaths in which trazodone was detected. Although the normal upper therapeutic blood concentration for trazodone is about 2 mg/L, fatalities are rarely attributed solely to it at blood concentrations below 9 mg/L. Considering the pharmacology of the drug, potential interactions between other drugs with serotonin reuptake properties need to be considered, as does the increased susceptibility to the toxic effects in patients with pre-existing heart disease. In the cases reviewed, none were attributed solely to trazodone, although trazodone was frequently present together with other serotonergic drugs, such as the selective serotonin reuptake inhibitors like fluoxetine and sertraline. Ten cases had blood trazodone concentrations above 2 mg/L. Of these cases, trazodone played a primary role in the death of three subjects, with blood concentrations all greater than 9 mg/L. We confirm the conclusions of others that trazodone is a relatively safe drug except in massive overdose, although its toxicity may be influenced by the presence of other drugs and underlying pathophysiology.
Clinical significance of angiopoietin-2 expression at the deepest invasive tumor site of advanced colorectal carcinoma (2004)

Angiopoietin (Ang)-2 and vascular endothelial growth factor (VEGF) are thought to be critical regulators in tumor angiogenesis. We investigated the clinical significance of Ang-2 expression at the deepest invasive tumor site under the influence of VEGF expression in relation to angiogenesis, invasive/metastatic potential, and prognosis of advanced colorectal carcinoma (CRC). One hundred and fifty-two patients who underwent surgical resection for advanced CRC were enrolled in this study. Ang-2 and VEGF expression were examined immunohistochemically. Tumor microvessel density (MVD) was examined by immunohistochemical staining against CD34. Ang-2 and VEGF were expressed at the deepest invasive tumor site in 90 (59.2%) and 64 (42.1%) of 152 lesions, respectively. Patients with Ang-2 expression at the deepest invasive tumor site showed significantly (p<0.01) more frequent poorly histologic grade (71.9%), lymphatic involvement (65.9%), venous involvement (69.1%), lymph node metastasis (75.0%), liver metastasis (80.0%) and advanced disease (Dukes' stage C, 70.2%; stage D, 80.0%) than patients without Ang-2 expression. MVD was not significantly up-regulated by Ang-2 expression alone at the deepest invasive tumor site but was significantly up-regulated by VEGF expression at the deepest invasive tumor site under the positive-Ang-2 condition. In patients treated by curative surgery, patients with tumors showing both positive-Ang-2 and positive-VEGF condition at the deepest invasive tumor site had significantly poorer prognoses than patients with tumors under other conditions. Multivariate analysis with logistic regression for 5-year survival in cases of curative surgery showed that lymph node metastasis, VEGF expression and Ang-2 expression were significant factors to predict poor prognosis. Our results suggest that Ang-2 expression in collaboration with VEGF expression at the deepest invasive tumor site may result in tumor angiogenesis and that these angiogenic factors at the deepest invasive tumor site may be correlated with invasive/malignant potential and prognosis of advanced CRC.
Use of Microsphere Technology for Targeted Delivery of Rifampin to <i>Mycobacterium tuberculosis</i> -Infected Macrophages (1998)

Microsphere technology was used to develop formulations of rifampin for targeted delivery to host macrophages. These formulations were prepared by using biocompatible polymeric excipients of lactide and glycolide copolymers. Release characteristics were examined in vitro and also in two monocytic cell lines, the murine J774 and the human Mono Mac 6 cell lines. Bioassay assessment of cell culture supernatants from monocyte cell lines showed release of bioactive rifampin during a 7-day experimental period. Treatment of Mycobacterium tuberculosis H37Rv-infected monocyte cell lines with rifampin-loaded microspheres resulted in a significant decrease in numbers of CFU at 7 days following initial infection, even though only 8% of the microsphere-loaded rifampin was released. The levels of rifampin released from microsphere formulations within monocytes were more effective at reducing M. tuberculosis intracellular growth than equivalent doses of rifampin given as a free drug. These results demonstrate that rifampin-loaded microspheres can be formulated for effective sustained and targeted delivery to host macrophages.
Tyrosine kinase activation by Newcastle disease virus is required for TNF- <i>alpha</i> gene induction in astrocytes. (1994)

Astrocytes, when appropriately stimulated, produce a variety of cytokines including TNF-alpha. Production of TNF-alpha by astrocytes stimulated with Newcastle disease virus (NDV) is achieved by transcriptional activation and mRNA stabilization. A PKC-dependent pathway is responsible for a 10-fold increase in TNF-alpha mRNA stability by reducing poly(A) tail removal. The present study examined signal pathways induced by NDV in primary rat astrocytes that are responsible for TNF-alpha gene transcription as well as the possible source of kinase activity required for mRNA stabilization. Transcription of TNF-alpha gene in astrocytes stimulated by NDV or LPS and IFN-gamma was inhibited completely by the tyrosine kinase inhibitor herbimycin, and partially by a PKC inhibitor H7, as determined by nuclear run-on assay. HA-1004, a cyclic nucleotide-dependent kinase inhibitor, showed no effect. These results indicated that tyrosine kinase signaling pathways seemed to precede the activation of PKC in induction of TNF-alpha gene. Increase in tyrosine kinase activity in NDV-infected astrocytes was demonstrated by a two- to threefold increase in tyrosine phosphorylation of Pl-PLC gamma 1. Because astrocytes contain minimal Pl-PLC beta, and NDV-induced TNF-alpha mRNA was affected by pertussis toxin only modestly, Pl-PLC gamma 1 is likely the enzyme responsible for DAG generation and the PKC-dependent mRNA stabilization in response to NDV.
Characterization of porous poly-silicon impregnated with Pd as a hydrogen sensor (2004)

Porous poly-silicon (PPS) samples, obtained by electrochemical anodization of p-type poly-silicon wafers, were doped with Pd by the electroless process. Rutherford backscattering spectroscopy shows that Pd has diffused a few micrometres into the PPS layer. Scanning electron microscopy and energy dispersive x-ray analysis results demonstrate the presence of Pd as dispersed clusters on the surface. The variation of the electrical resistance in the presence of dry air diluted with hydrogen at room temperature shows that Pd/PPS samples have the ability to sense hydrogen at levels down to several thousands of ppm. This value is far below the flammability limit of hydrogen gas. It was found that the increase in the time of anodization causes an increase in the penetration depth of Pd and, consequently, an increase in the sensitivity to hydrogen. By raising the device temperature to 60°C, the sensor response falls.
Serotonin-stimulated calcium release is decreased in platelets from high impulsivity patients (2000)

Impulsivity is a significant factor in many behavioural disorders. Previous studies have shown that dysfunction of serotonin (5-HT) pathways are correlated with impulsivity, but an underlying causative mechanism has not as yet been identified. The present study examined 5-HT-stimulated Ca2+ release from platelets from 33 patients exhibiting high impulsivity according to the Barratt Impulsivity Scale and from 26 healthy volunteers. 5-HT-stimulated Ca2+ release was significantly decreased in patients as compared to controls. These results indicate that impulsivity is linked to alterations in the 5-HT second-messenger cascade and suggest that further efforts should be made to understand the specific abnormalities in this complex pathway. This understanding may lead to the development of therapeutic strategies specific for regulation of 5-HT-stimulated Ca2+ release, providing more effective treatment for impulsive behavioural disorders.
Polycythemia vera and other primary polycythemias (2005)

The existence of family clustering of PV may facilitate the search for PV molecular basis. Only collaborative interaction of clinical researchers and laboratory scientists will lead to meaningful progress in determining the molecular basis of PV.
Biogenesis of the mycobacterial cell wall and the site of action of ethambutol (1995)

The effect of ethambutol (EMB) is primarily on polymerization steps in the biosynthesis of the arabinan component of cell wall arabinogalactan (AG) of Mycobacterium smegmatis. Inhibition of the synthesis of the arabinan of lipoarabinomannan (LAM) occurred later, and thus in the cases of AG and LAM, the polymerization of D-arabinofuranose apparently involves separate pathways. While the synthesis of these arabinans was normal in an EMB-resistant isogeneic strain, the addition of EMB to the resistant strain resulted in partial inhibition of the synthesis of the arabinan of LAM and the emergence of a novel, truncated form of LAM, indicating partial susceptibility of the resistant gene(s) and providing a new intermediate in the LAM biosynthetic sequence. A consequence of inhibition of AG arabinan biosynthesis is the lack of new sites for mycolate attachment and thus the channeling of mycolate residues into a variety of free lipids which then accumulate. The primary biochemical effects of EMB can be explained by postulating separate AG and LAM pathways catalyzed by a variety of extramembranous arabinosyl transferases with various degrees of sensitivity to EMB.
Diclofenac and Enolicam as Ocular Anti-Inflammatory Drugs in Rabbit Corneal Wound Model (1986)

The anti-inflammatory effects of two nonsteroidal agents, enolicam and diclofenac, were assessed in rabbit corneal wound model. Topically applied diclofenac (50 microliter volume) at 0.01%, 0.1% and 0.5% concentrations inhibited the polymorphonuclear leukocyte (PMN) release into tear fluid following partial (6 mm central area) corneal deepithelialization in rabbits. Similarly, enolicam also inhibited this PMN response following corneal injury. Topical diclofenac was found to be more potent than topical enolicam in inhibiting the inflammatory PMN response following partial corneal injury. Both drugs did not affect the rate of reepithelialization following complete (limbal to limbal) corneal deepithelialization.
Elastic Waves in Electromagnetic Launchers (2006)

Elastic waves are considered as a contributing factor to solid armature transition in guide rail launchers. The transient elastic waves in the rails of electromagnetic launchers are studied as well as the normal contact pressure between the rails and the armature. We have shown that, due to the interference of elastic waves, the contact pressure between the armature and rail will change dramatically as the armature goes through the critical velocity. This paper explores the effects of transverse magnetic pressure on the trailing arms of a "C"-shaped armature
Single-electron charging effects in insulating wires. (1991)

We present measurements of the transport properties of 0.75-\ensuremath{\mu}m-long, narrow, insulating indium oxide wires and rings. These devices have no apparent tunnel barriers, yet they exhibit effects similar to those found in series arrays of very small-capacitance tunnel junctions: highly nonlinear I-V characteristics and a zero-bias conductance which is periodic in a voltage applied by means of a lateral gate. These effects are due to the influence of single-electron charging on transport through localized states in the insulating regime.
Acute Pancreatic Lesions in Patients Treated with ACTH and Adrenal Corticoids (1957)

CASUAL observations of post-mortem material have suggested an increased frequency of necrosis and other lesions in the pancreas and adjacent tissues in patients receiving certain adrenocortical steroids or ACTH. The present study is an attempt at a more accurate quantitative evaluation of these findings.Our interest was stimulated by reports from two laboratories of pancreatic lesions induced by cortisone in rabbits. Stumpf and his co-workers1 found changes in pancreatic acini in 44 of 53 cortisone-treated animals and peripancreatic fat necrosis in 13 of these animals. Bencosme and Lazarus2 described similar lesions in their series of rabbits treated with this steroid. . . .
Speed sensorless field-oriented control of induction motor with rotor resistance adaptation (1994)

Several field-oriented induction motor drive methods without rotational transducers have been proposed. These methods have a disadvantage that the rotor resistance variation causes an estimation error of the motor speed. Therefore, simultaneous estimation of the motor speed and the rotor resistance is required. This paper presents a method of estimating simultaneously the motor speed and the rotor resistance of an induction motor by superimposing AC components on the field current command. The validity of the proposed method is verified by simulation and experimentation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Radiation Effects in Flash Memories (2013)

We review ionizing radiation effects in Flash memories, the current dominant technology in the commercial non-volatile memory market. A comprehensive discussion of total dose and single event effects results is presented, concerning both floating gate cells and peripheral circuitry. The latest developments, including new findings on the mechanism underlying upsets due to heavy ions and destructive events, are illustrated.
Photodynamic Therapy for Localised Prostatic Cancer: Light Penetration in the Human Prostate Gland (1990)

We are investigating the feasibility of photodynamic therapy in the treatment of localised prostatic cancer. Of major importance in this form of treatment is the extent to which light penetrates the target organ; hence, our interest in the optical properties of the human prostate gland. We obtained three whole prostates from autopsies of patients who died of non-urological causes. Red light was launched interstitially and detector fibres measured light intensity as a function of distance from the delivery fibre end. The optical constants derived from the three prostates were almost identical and indicated that light was predominantly scattered rather than absorbed (mean absorption and scattering coefficients 0.07 +/- 0.02 mm.-1 and 0.86 +/- 0.05 mm.-1 respectively). In a comparison of the tissue penetration by four different wavelengths, 633 nm red light was found to be transmitted best. Light propagation in the heavily absorbing tissue of the human liver was 4.3 times poorer than in the prostate. Such a combination of low absorption and high scattering characteristics in prostatic tissue would enhance the effectiveness of PDT. The optical constants derived will enable "light treatment planning" in patients with prostatic cancer.
Effects of Shear Planes and Interfacial Slippage on Fracture Growth and Treating Pressures (1998)

Abstract The equations used in current hydraulic fracture simulators are based on plane-strain solutions, or use a complete surface integral solution for fracture width. Assumptions inherent in these solutions control the stress field surrounding the fracture tip and the stress intensity developed at the tip which, in turn, controls the rate of fracture growth and containment and the predicted net pressure. The overriding assumption made in these solutions is that the entire rock mass is elastically coupled so that all stresses and deformations interact. Many reservoirs that are hydraulically fractured are susceptible to complex fracturing which can invalidate the assumption of elastic coupling. Microseismic monitoring of fracture growth indicates that energy is lost to shear failures around the fracture. During hydraulic fracturing high fluid pressures, often exceeding both the minimum and maximum horizontal stress (fissure opening pressure), result in the reduction of the normal stress acting across natural fissures. This allows free shear or slippage along natural fracture planes in reservoirs or cleats in coal. When shear or slippage occurs elastic coupling in the rock mass is lost and each shear block deforms as a separate unit. This shear decoupling results in tremendous reduction in created fracture width and leads to high frictional pressures (low transmissibility) and difficulty in placing proppant, especially large proppant. The purpose of this work is to suggest that current fracture models are missing what could be a dominant containment mechanism in the fracturing of fissured reservoirs, coals, and soft rocks and that further work is required to fully understand the implications of slippage and shear failure on treatment designs.
