Reactor channel heatup effects during postulated accident conditions of LOCA and unavailability of ECCS in 540 MWe Indian PHWRs (2005)

Full text of publication follows: The Indian PHWRs are horizontal type reactors, which contain heavy water moderator and natural UO{sub 2} in number of horizontal coolant tubes. This paper assesses fuel and fuel channel behavior under high temperature transient accident conditions as might arise during a postulated LOCA(Loss of coolant accident) with ECCS(Emergency core cooling system) presumed to be unavailable. Under such conditions, the moderator provides heat sink for the heat produced in the reactor. During postulated LOCA with ECCS failure, following voiding in the channels heat generated in fuel bundles is transferred by radiation to the pressure tube and calandria tube and then convective heat transfer to the moderator. As radiation is the principal mode of heat transfer, high fuel and pressure tube temperatures results. At the elevated temperature, the metal water reaction of sheath and pressure tube produces significant heat and deuterium. Significant sheath failure is also predicted. The pressure tube deforms and contact to calandria tube. The initial contact between hot pressure tube and cold calandria tube result in a sudden increase in the heat flux to the moderator. This heat flux would depend on the stored energy in fuel and pressure tube at the time of contact and conductance between the pressure tube and calandria tube. The magnitude of peak heat flux combined with the temperature of water surrounding the calandria tube determines the boiling regime on the calandria tube surface and thus the rate of heat removal. This work starts analyzing the condition from the starting of LOCA. The present work uses Thermal Hydraulics neutronics code ATMIKA for hydrodynamic analysis and Thermal Hydraulic code CONTACT for thermal and mechanical behavior of coolant channel. A detailed analysis has been carried out for the scenario, involving different types of LOCA with ECCS Unavailable. The following cases are analyzed. 1. Critical break LOCA in Reactor Inlet Header with ECCS unavailable. 2. 100% break LOCA in Reactor Inlet Header with ECCS unavailable. 3. 100% break LOCA in Reactor Outlet Header with ECCS unavailable. 4. 100% break LOCA in Pump Suction line with ECCS unavailable. The sheath temperatures, Zr. Oxidation in fuel bundles, deuterium generation, fuel failure and heat load to moderator are predicted. It is found that the 100% ROH break case is severe one and has maxima of temperature, deuterium generation and fuel failures. (authors)
Retrotransposons (2018)

Retrotransposons constitute an extensively distributed family of eukaryotic transposable elements. The retrotransposons share a number of structural features which reflect the mechanism by which new copies of the transposon are generated; this process is similar to that of retroviral reverse transcription and integration. The marked progeny transposons occasionally showed evidence of heterogeneity with respect to the parental plasmid-borne element. A highly speculative but stimulating model for the retrotransposition of the DIRS1 element of Dictyostelium discoideum has been proposed by Cappello et al. The transcription of IAP elements is very much elevated in most tumor cell lines. This corresponds with original observations on the presence of Intracistemal A-particle particles in various cell lines. All elements of a family are probably affected transcriptionally by the sequences adjacent to them. Retrotransposons often are associated with the ability to activate the transcription of adjacent genes. Moreover, this activation is often under the same type of regulation as is the retrotransposon itself.
Synthesis and Assessment of Globotriose–Chitosan Conjugate, a Novel Inhibitor of Shiga Toxins Produced by Escherichia coli (2012)

Shiga toxin (Stx)-producing Escherichia coli (STEC) causes diarrhea and colitis in humans that can develop into a life-threatening hemolytic uremic syndrome (HUS). Developing efficient means of controlling STEC diseases, for which no drugs or vaccines are currently available, remains a high priority. We report here the construction and development of chitosan conjugates bearing the Stx ligand trisaccharide globotriose to demonstrate their potential as STEC disease treatment agents. The synthesis was accomplished by grafting a globotriose derivative containing an aldehyde-functionalized aglycone to chitosan amino groups. The obtained globotriose-chitosan conjugate bound with high affinity to Stx and efficiently neutralized its toxicity on Vero cells. Moreover, Stx levels in the gut of infected mice receiving oral doses of the conjugate were greatly diminished, enabling the mice to resist a fatal STEC challenge. The conjugate appears to function as a Stx adsorbent in the gut, preventing toxin entry into the bloodstream and consequent development of HUS. As such, the conjugate could act as a novel agent against STEC disease.
Extracting Chinese question-answer pairs from online forums (2009)

Extracting question-answer pairs from online forums is a meaningful work due to the huge amount of valuable user generated resource contained in forums. In this paper we consider the problem of extracting Chinese question-answer pairs for the first time. We present a strategy to detect Chinese questions and their answers. We propose a sequential rule based method to find questions in a forum thread, then we adopt non-textual features based on forum structure to improve the performance of answer detecting in the same thread. Experimental results show that our techniques are very effective.
Patients with Congenital Factor V Deficiency have Decreased Factor Xa Binding Sites on their Platelets (1978)

Human platelets have binding sites for plasma coagulation Factor X(a) that are available only after the platelet release reaction. Platelets from 15 normal donors bound 216+/-52 (SD) molecules of Factor X(a) per platelet. The association of Factor X(a) with its platelet surface receptor results in a 300,000-fold increase in the catalytic activity of Factor X(a) in forming thrombin from prothrombin. The turnover number for platelet-bound Factor X(a) was 1,850+/-460 mol thrombin/ml per min per mol Factor X(a) in experiments with platelets from 15 normal donors. Platelets from five patients with varying degrees of Factor V deficiency were investigated to determine whether or not coagulation Factor V participates in either aspect of the Factor X(a)-platelet interaction. The binding of Factor X(a) to platelets and the accompanying increase in rate of thrombin formation were either reduced in parallel or absent in each case with values ranging from 0 to 45% of control values. The apparent affinity of Factor X(a) from Factor V-deficient patients was normal when platelet binding was detected. The supernate from thrombin-treated control platelets, which contains Factor V activity, corrected the Factor X(a) binding deficiency of the platelets from three patients tested. Immunoreactive Factor V determined with an homologous antibody corresponded to the functional Factor V activity of platelets from one patient with Factor V deficiency, suggesting that the patient's platelets have a decreased amount of normal Factor V. The ability of platelets from the patients to bind Factor X(a) and increase the rate of thrombin formation correlated with the severity of each patient's bleeding disorder better than the plasma level of Factor V. The results indicate that Factor V is required for the Factor X(a)-platelet interaction and that thrombin formation at the platelet surface is important in normal hemostasis.
Ink Flow Patterns In Multi Color Inkjet Images And Their Impact On Graininess Noise (2020)

Graininess noise is a common artifact in inkjet printing. While current inkjet printing technologies attempt to control graininess in single color images, the results are often less than optimal for multi-color images. This is due to fluidic interactions between inks of different colors. This paper will describe a color decomposition methodology that can be used to study ink flow patterns in multi-color inkjet printed images at a microscopic scale. This technique is used to decompose multi-color images into several independent color components. The ink patterns in these components are analyzed to relate them to visually perceptible graininess noise.
Topical Liposome Targeting of Dyes, Melanins, Genes, and Proteins Selectively to Hair Follicles (1998)

For therapeutic and cosmetic modification of hair, we have developed a hair-follicle-selective macromolecule and small molecule targeting system with topical application of phosphatidylcholine-based liposomes. Liposome-entrapped melanins, proteins, genes, and small-molecules have been selectively targeted to the hair follicle and hair shafts of mice. Liposomal delivery of these molecules is time dependent. Negligible amounts of delivered molecules enter the dermis, epidermis, or bloodstream thereby demonstrating selective follicle delivery. Naked molecules are trapped in the stratum corneum and are unable to enter the follicle. The potential of the hair-follicle liposome delivery system for therapeutic use for hair disease as well as for cosmesis has been demonstrated in 3-dimensional histoculture of hair-growing skin and mouse in vivo models. Topical liposome selective delivery to hair follicles has demonstrated the ability to color hair with melanin, the delivery of the active lac-Z gene to hair matrix cells and delivery of proteins as well. Liposome-targeting of molecules to hair follicles has also been achieved in human scalp in histoculture. Liposomes thus have high potential in selective hair follicle targeting of large and small molecules, including genes, opening the field of gene therapy and other molecular therapy of the hair process to restore hair growth, physiologically restore or alter hair pigment, and to prevent or accelerate hair loss.
TOWARDS UNIFIED SERVICE HOSTING (2009)

Service-oriented computing is increasingly assuming an important role in the research on distributed systems and software engineering. It has also reached application and service hosters by now who need to be able to host off-the-shelf services as well as custom services. Thus, they are faced with a variety of service descriptions, service package formats and runtime demands. Each service technology usually requires a separate execution platform which eventually leads to a high complexity for the administration and management of services. Similar to the unification of invocation of web services through protocol adapters, it is clearly needed to unify management aspects like monitoring and adaptation of services. We therefore propose an abstraction, a formalisation and a unification layer for hosting environments with the intent to pave the wayion, a formalisation and a unification layer for hosting environments with the intent to pave the way for technology-agnostic, unified service hosting.
Optimization of NO oxidation by H2O2 thermal decomposition at moderate temperatures (2018)

H2O2 was adopted to oxidize NO in simulated flue gas at 100-500°C. The effects of the H2O2 evaporation conditions, gas temperature, initial NO concentration, H2O2 concentration, and H2O2:NO molar ratio on the oxidation efficiency of NO were investigated. The reason for the narrow NO oxidation temperature range near 500°C was determined. The NO oxidation products were analyzed. The removal of NOx using NaOH solution at a moderate oxidation ratio was studied. It was proven that rapid evaporation of the H2O2 solution was critical to increase the NO oxidation efficiency and broaden the oxidation temperature range. the NO oxidation efficiency was above 50% at 300-500°C by contacting the outlet of the syringe needle and the stainless-steel gas pipe together to spread H2O2 solution into a thin film on the surface of the stainless-steel gas pipe, which greatly accelerated the evaporation of H2O2. The NO oxidation efficiency and the NO oxidation rate increased with increasing initial NO concentration. This method was more effective for the oxidation of NO at high concentrations. H2O2 solution with a concentration higher than 15% was more efficient in oxidizing NO. High temperatures decreased the influence of the H2O2 concentration on the NO oxidation efficiency. The oxidation efficiency of NO increased with an increase in the H2O2:NO molar ratio, but the ratio of H2O2 to oxidized NO decreased. Over 80% of the NO oxidation product was NO2, which indicated that the oxidation ratio of NO did not need to be very high. An 86.7% NO removal efficiency was obtained at an oxidation ratio of only 53.8% when combined with alkali absorption.

Plasma immunoreactive gastric inhibitory polypeptide in obese hyperglycaemic (ob/ob) mice (1984)

Gastric inhibitory polypeptide (GIP), a recognized component of the enteroinsular axis, is raised in the plasma and intestine of obese hyperglycaemic (ob/ob) mice. To evaluate the control of plasma GIP and its role in the hyperinsulinaemia of the ob/ob syndrome, GIP and insulin were determined at different ages in fed mice, and at 10-12 weeks of age after fasting/refeeding and administration of GIP, different nutrients and insulin to mice fasted for 18 h. Plasma GIP and insulin were raised in adult (10- and 20-week-old) compared with younger (3- and 5-week-old) mice, although GIP was not increased in the presence of hyperinsulinaemia at 3 weeks of age. Fasting suppressed and refeeding promptly restored plasma GIP and insulin concentrations. Administration of GIP to mimic postprandial concentrations evoked a marked but transient insulin response which was protracted in the presence of rising hyperglycaemia. Orally administered fat, glucose and amino acids raised GIP concentrations with fat having a particularly strong effect. Glucose and amino acids also evoked prominent increases of insulin, but fat produced only a small rise in insulin in the absence of increasing glucose concentrations. Consistent with glucose-potentiation, a mixture of all three nutrients greatly augmented the insulin response without further increase of plasma GIP. Glucose-induced increase in endogenous insulin and doses of exogenous insulin up to 100 units/kg did not suppress basal, fat-stimulated or glucose-stimulated GIP release. The results indicate that raised GIP concentrations make an important contribution to the hyperinsulinaemia and related metabolic abnormalities of the ob/ob syndrome.
The growth‐supportive effect of thrombospondin (TSP1) and the expression of TSP1 by human MG‐63 osteoblastic cells are both inhibited by dexamethasone (1993)

Thrombospondin (TSP) is a 450-kDa extracellular matrix glycoprotein which supports the growth of human MG-63 osteoblastic cells [Abbadia et al., FEBS Lett., 329 (1993) 341-346]. In this study, we describe the effect of the glucocorticoid, dexamethasone, on cell proliferation and TSP expression by MG-63 cells. Using a serum-free mitogenesis assay, dexamethasone (25 to 500 nM) caused a dose-dependent decrease in [3H]thymidine incorporation by MG-63 cells in culture, reaching 40% inhibition of cell proliferation at a concentration of 250 nM. Similarly, the stimulatory effect of TSP (500 ng/ml) on proliferation of MG-63 cells was totally abolished in the presence of dexamethasone (250 nM). In situ hybridization indicated that TSP mRNA level in dexamethasone-treated MG-63 cells decreased compared to quiescent cells. As judged by fluorescence-activated cell sorting analysis, dexamethasone treatment of MG-63 cells resulted in a 50 to 70% decrease in TSP cell surface expression compared to quiescent cells. Secretion of TSP in the culture fluid of dexamethasone-treated MG-63 cells also decreased by 40% while, under similar experimental conditions, a 180% increase in alkaline phosphatase activity was observed in dexamethasone-treated cells. Because glucocorticoids induce osteoporosis in vivo and reduce proliferation of osteoblasts in vitro, our results argue for an important role of TSP during bone formation.
Unique crystallization behavior in zeolite synthesis under external high pressures (2020)

The function of pressure has long been overlooked in the hydrothermal synthesis of zeolites, which is typically carried out under an autogenous pressure (below 2 MPa). We herein report, the first of its kind, a detailed investigation on the hydrothermal synthesis of zeolites under external high pressures, where crystallization behaviors contradicting the common observations were generated.
Epigenetic Mechanisms of Long-Term Effects of Mother-Infant Relationship on Physiology and Behavior of the Offspring. (2018)

The quality of mother-infant relationship in the early postnatal period influences the neurophysiology and behavior of adult animals via epigenetic mechanisms. The most studied target of long-term effects of early life events on physiology and behavior is hypothalamic-pituitary-adrenal axis, in particular, epigenetic programming of glucocorticoid receptor gene expression. Inhibition of histone deacetylases is a tool for epigenetic modulation of nervous system plasticity. Using this approach, it was demonstrated that epigenetic mechanisms play an important role in physiological and behavioral modifications. It is also promising tool for reversing the negative effects of disturbances in the mother-infant relationship early in life. To date, however, the use of histone deacetylase inhibitors is widespread in adult animals, while studies in the early postnatal period are still scarce despite their relevance.
Gas Chromatographic/Mass Spectrometric Study of Isoequilin A (1981)

Abstract Isoequilin A, which is produced by the acid-induced isomerization of equilin, has been resolved into 3 major components by gas chromatography. Tentative identification of the 3 compounds was made by using combined gas chromatography/mass spectroscopy. One of these compounds, identified as 8-dehydroestrone, closely resembled a component previously identified in pregnant mares’ urine.
Clinical implementation of a neonatal seizure detection algorithm (2014)

Technologies for automated detection of neonatal seizures are gradually moving towards cot-side implementation. The aim of this paper is to present different ways to visualize the output of a neonatal seizure detection system and analyse their influence on performance in a clinical environment. Three different ways to visualize the detector output are considered: a binary output, a probabilistic trace, and a spatio-temporal colormap of seizure observability. As an alternative to visual aids, audified neonatal EEG is also considered. Additionally, a survey on the usefulness and accuracy of the presented methods has been performed among clinical personnel. The main advantages and disadvantages of the presented methods are discussed. The connection between information visualization and different methods to compute conventional metrics is established. The results of the visualization methods along with the system validation results indicate that the developed neonatal seizure detector with its current level of performance would unambiguously be of benefit to clinicians as a decision support system. The results of the survey suggest that a suitable way to visualize the output of neonatal seizure detection systems in a clinical environment is a combination of a binary output and a probabilistic trace. The main healthcare benefits of the tool are outlined. The decision support system with the chosen visualization interface is currently undergoing pre-market European multi-centre clinical investigation to support its regulatory approval and clinical adoption.
An approach to localization in crowded area (2016)

Every year millions of people gather at Makkah, Saudi Arabia during the Hajj, an annual Islamic pilgrimage. The area at Makkah is small, and the number of attendees increases each year, which has created an ongoing and ever increasing problem of crowd management. In this paper, we present our integrated solution to the localization challenge of tracking specific users in a highly crowded area where GPS signal may be weak or even unavailable. Smartphone based Human Activity Recognition (HAR) uses various sensors that are built into the smartphone to sense a person's activity in real time. Applications that incorporate HAR can be used to track a person's movements and are very useful in areas such as health care. We also propose a group-tracking mechanism that can be applied when a group member appears to get lost. Other members of the group will be immediately notified and receive an estimation of the lost member's location. Using wireless signals (RSSI) and inertial sensor data, we have developed a mathematical model and a system for both outdoor and indoor localization. The experimental results show that the proposed system is able to detect locations of users with high accuracy, with an error of less than 2.5 meters. The system will be used by millions of users in Makkah, where there have been thousands of reported cases of pilgrims getting lost during the Hajj, however, it is scalable to accommodate any other crowded population.
