Synthesis and Morphological Control of Europium Doped Cadmium Sulphide Nanocrystals (2011)

Europium doped cadmium sulphide (Cd(0.98)Eu(0.2)S) nanostructures were synthesised by chemical co-precipitation method using ethylene glycol (EG) and deionized water (Eu:CdS-1), and isopropyl alcohol (IPA) and deionized water (Eu:CdS-2) as mixed solvents. It has been found that the nanostructure of the europium doped CdS can be controlled by simply varying the mixed solvent system. Powder XRD pattern reveals the formation of hexagonal (wurtzite) and cubic (zinc blende) structure for Eu:CdS-1, and Eu:CdS-2, respectively. The crystallite size of the sample prepared using IPA and deionized water was measured to be 2.64 nm which is much smaller than that of the sample prepared using EG and deionized water as mixed solvent (3.65 nm). Morphology of the materials can also be changed from flower shaped crystals to paddy like structures by varying the mixed solvents. Band gap values of Eu3+ doped CdS nanocrystals synthesized from two different solvents were estimated using UV-reflectance spectra. The size and crystallinity of the samples were confirmed by HRTEM and SAED analysis. A significant change in the PL emission of the CdS nanocrystals was observed for the europium doped CdS which is mainly due to the presence of EU3+ ions which also play a significant role in the energy transfer process. It was also observed that the shift in the emission and efficiency depends on size and shape of the synthesised nanoparticles.
Effects of the intercalation rate on the layered crystal structures and stimuli-responsive color-change properties of polydiacetylene (2017)

The layered structures and stimuli-responsive color-change properties of polydiacetylene, an organic layered material, are changed even in the partial intercalation states of the guest ions.
Researches in terrestrial magnetism and electricity at Department of Terrestrial Magnetism, Carnegie Institution of Washington, during April, 1943, to May, 1944 (1944)

The retarding effect of the war on the execution of the normal program of the Department has again made itself felt during the year. Communications between countries have become more and more difficult and scientific research has been progressively orientated to meet the requirements of modern war. Many established organizations and observatories have found it possible to maintain a part, if not the whole, of their normal activities and accordingly the loss of continuity of accumulating data on land has not been total. Naval operations, on the other hand, have precluded the collecting of observations at sea, thus preventing the maintenance of isomagnetic charts upon which navigation and some phases of the activities of war depend. The investigation of special war‐problems, however, has resulted in the development of many items of scientific value.

FORMATION OF HIGHLY CONDUCTING DERIVATIVES OF POLYACETYLENE THROUGH OXIDATION WITH SELECTED METAL HALIDES (1983)

Some new metal halides (InCl3, InI3, TiCl4, TiI4, SnCl4, ZrCl4) can oxidize polyacetylene with the formation of highly conducting polymers characterized by elemental analysis, mass uptake and physical methods. Electrical conductivities and EPR spectra are in agreement with the metallic behaviour of these new materials.
Adsorption isotherm, kinetic and mechanism studies of 2-nitrophenol on sedimentary phosphate (2015)

Sedimentary phosphate (SP) was used as an adsorbent for the removal of 2-nitrophenol from aqueous solutions in an attempt to investigate (the feasibility of) its application (to) in wastewater purification.Â The adsorbent was characterized by X-ray diffraction (XRD), IR spectroscopy, Fluorescence X and BET.Â The results indicated that the SP (was) is francolite (Ca10 (PO4,CO3)6F2) and mesoporous. The effect of the adsorption time and the pH of the solution were studied. The pseudo-first-order, pseudo-second-order and intraparticle diffusion models were used to fit adsorption data in the kinetic studies. The equilibrium isotherms were determined using the Langmuir, Freundlich and Dubinin-Radushkevich models. The results show that the Dubinin-Radushkevich isotherm had better agreement with the 2-nitrophenol adsorption on SP with a correlation coefficient of 0.98, an equilibrium adsorption capacity of 633 mg. g-1 and a corresponding contact time of 2 h. The results imply that intraparticle diffusion could be summarized as the basic rate-controlling mechanisms during 2-nitrophenol adsorption on SP.
Characteristic time for halo current growth and rotation (2015)

A halo current flows for part of its path through the plasma edge and for part through the chamber walls and during tokamak disruptions can be as large as tenths of the plasma current. The primary interest in halo currents is the large force that they can exert on machine components particularly if the toriodal rotation of the halo current resonates with a natural oscillation frequency of the tokamak device. Halo currents arise when required to slow down the growth of a kink that is too unstable to be stabilized by the chamber walls. The width of the current channel in the halo plasma is comparable to the amplitude of the kink, and the halo current grows linearly, not exponentially, in time. The current density in the halo is comparable to that of the main plasma body. The rocket force due to plasma flowing out of the halo and recombining on the chamber walls can cause the non-axisymmetric magnetic structure produced by the kink to rotate toroidally at a speed comparable to the halo speed of sound.

CAD to SIM: CAD Model Conversion for Dymola-based Mechatronic Simulation (2008)

Virtual product development allows us to recognize and evaluate the characteristics of a new product on the basis of simulation at an early stage without having to build a physical prototype. Currently the most, widely spread CAE systems do not have multi-domain simulation support, nor do offer direct interfaces to external dynamic simulation applications. These systems disallow the complex simulation of the designed virtual product. Conversely, dynamic simulation of a detailed virtual prototype is required to maintain good correlation between the behaviour of the real product and its virtual counterpart. In this paper a largely automated workflow will be presented, how a convenient conversion can be achieved to Modelica models from the output of a CAD system considering Dymola-based multi-domain simulation.
[New drugs in asthma treatment. Leukotriene receptor blockers and leukotriene synthesis inhibitors]. (1997)

Asthma is an inflammatory airway disease. The patient is characterised by increased mucus secretion, mucosal oedema, bronchial obstruction of varying degree and bronchial hyperresponsiveness. Several cell types and a large number of mediators are involved in asthma-related inflammation and constriction of the airways. The leukotrienes constitute an important group of mediators in asthmatic inflammation. The study of specific leukotriene receptor antagonists and biosynthesis inhibitors has not only shed light on the underlying mechanisms in asthma, but also opened up the way to new treatment alternatives. As zafirlukast, a leukotriene receptor antagonist has just been licensed in Finland, it is a suitable opportunity to review the importance of leukotrienes in asthma and the use of agents that affect them.
Actinonin, a meprin A inhibitor, protects the renal microcirculation during sepsis (2009)

Meprin A, a matrix metalloproteinase highly expressed in the kidney and reported to be an early biomarker of acute kidney injury (AKI), is thought to play an important role in several causes of AKI. To address the role of meprin A in the early microcirculatory dysfunction associated with sepsis‐induced AKI, we studied the effects of the meprin A inhibitor actinonin in the cecal ligation and puncture (CLP) model of sepsis in the mouse. Male C57BL/6 mice (40 weeks) underwent CLP with vehicle (CLPv) or actinonin at 20 mg/kg, ip (CLPact) 30 min prior to CLP. At 7h post CLP, intravital videomicroscopy was utilized to image renal cortical peritubular capillary perfusion. Actinonin prevented the fall in renal capillary perfusion. The percentage of capillaries with continuous perfusion in CLPv and CLPact were 50 ± 9% and 83 ± 10% respectively (P &lt; .05) and the percentage with no perfusion in CLPv and CLPact were 33 ± 10% and 7 ± 2% respectively (P &lt; .05). Capillary perfusion in CLPact was no different from sham mice. Since meprin A is known to activate the proform of IL‐1β, serum IL‐1β was used to assess the inhibitory activity of actinonin. IL‐1β levels decreased in CLPact by 36% compared to CLPv at 7h (P &lt; .05). These data suggest that meprin A may play an important role in the microcirculatory failure associated with sepsis‐induced AKI and that actinonin should be evaluated further as a possible therapeutic agent.

Tracking bridge tilt behaviour using sensor fusion techniques (2020)

Abstract The resilience of the built environment to extreme weather events is fundamental for the day-to-day operation of our transport network, with scour representing one of the biggest threats to bridges built over flowing water. Condition monitoring of the bridge using a structural health monitoring system enhances resilience by reducing the time needed to return the bridge to normal use by providing timely information on structural condition and safety. The work presented in this report discusses use of rotational measurements in structural health monitoring. Traditionally tiltmeters (which can be a form of DC accelerometer) are used to measure rotation but are known to be affected by dynamic movements, while gyroscopes react quickly to dynamic motion but drift over time. This review will introduce gyroscopes as a complementary sensor for accelerometer rotational measurements and use sensor fusion techniques to combine the measurements from both sensors to get an optimised rotational result. This method was trialled on a laboratory scaled model, before the system was installed on an in-service single-span skewed railway bridge. The rotational measurements were compared against rotation measurements obtained using a vision-based measurement system to confirm the validity of the results. An introduction to gyroscopes, field test measurement results with the sensors and their correlation with the vision-based measurement results are presented in this article.
Bell inequalities for three systems and arbitrarily many measurement outcomes (2012)

We present a family of Bell inequalities for three parties and arbitrarily many outcomes, which can be seen as a natural generalization of the Mermin-Bell inequality. For a small number of outcomes, we verify that our inequalities define facets of the polytope of local correlations. We investigate the quantum violations of these inequalities, in particular with respect to the Hilbert space dimension. We provide strong evidence that the maximal quantum violation can be reached only using systems with local Hilbert space dimension exceeding the number of measurement outcomes. This suggests that our inequalities can be used as multipartite dimension witnesses.
Sortilin exhibits tumor suppressor-like activity by limiting EGFR transducing function (2021)

SUMMARY Lung cancer is the leading cause of cancer deaths worldwide and remains one of the most incurable. Tyrosine kinase receptors, such as the epidermal growth factor receptor (EGFR), are often aberrantly activated and drive tumor growth. Monotherapy with tyrosine kinase inhibitors to deactivate EGFR has shown initial efficacy, but their benefits tend to decline over time. EGFR acts as a transcriptional factor promoting the expression of co-oncogenic drivers, which, in turn, interact with canonical EGFR mutations to induce therapeutic relapse. This study reports that sortilin, a crucial regulator of cytoplasmic EGFR, attenuates its transducing function. Genome-wide chromatin binding revealed that sortilin interacts with gene regulatory elements occupied by EGFR. These results suggest a model, in which sortilin exhibits potential tumor suppressor-like activity by concurrently binding to regulatory elements of cMYC . Sortilin expression in lung adenocarcinoma may be predictive of the efficacy of anti-EGFR strategies.
Lecanicillium sabanense sp. nov. (Cordycipitaceae) a new fungal entomopathogen of coccids (2015)

A new species of Lecanicillium was found associated with the soft scale insect Pulvinaria caballeroramosae (Coccidae), an important pest of Ficus soatensis (Moraceae) in Bogotá, Colombia. Lecanicillium sabanense sp. nov. differs from similar Lecanicillium spp. mainly in the size of the conidia, in the vertical arrangement of phialides on the host, and in the tomentose mycelium that sparsely covers the cuticle of the host. Phylogenetic analyses using ITS, SSU, LSU, TEF, RPB1, and RPB2 also confirmed the distinctness of this new species. Fungal epizootics were found on female soft scale insects, which may have implications for biological control in the forestry program of the city. The ecology of the fungus as well as its potential use as a biological control agent are further discussed.
A Population‐Based Twin Study on Sleep Duration and Body Composition (2011)

The aim of this study is to investigate the relationship between sleep duration and body composition and to estimate the genetic contribution of sleep duration and body composition in a Chinese twin population. This cross-sectional analysis included 738 men and 511 women aged 21-72 year. Anthropometric and dual-energy X-ray absorptiometry (DXA) measures of body composition were used. Sleep duration was obtained from a standard sleep questionnaire. Multiple regression models were used to examine the association between sleep duration and body composition measures. Structural equation modeling was used to assess the heritability of sleep duration and body composition. Compared with individuals in the 2nd and 3rd age-specific quartiles of sleep duration (reference group), shorter (1st quartile) sleep duration among women but not men was associated with higher z-scores (0.248-0.317) for all adiposity measures--BMI, fat mass index (FMI), percent body fat mass (%BF), and percent trunk fat mass (%TF), P < 0.05 for each--and with 0.306 lower z-scores for percent body lean mass (%LM) and 0.353 lower lean/fat mass ratio (LFR), P < 0.01 for each. The heritability of sleep duration was 0.27 in men and 0.29 in women, while the heritability of body composition was as high as 0.56-0.73 after adjustment for age in both genders. Short sleep duration was associated with increased body fat and decreased lean body mass in women but not in men. Sleep duration was largely influenced by environmental factors while adiposity measures were mainly influenced by genetic factors.

A kinetic investigation of the hydroxide-catalysed detritiation of various [16-3H]-15,16-dihydrocyclopenta[a]phenanthren-17-ones and related compounds (1985)

The hydroxide-catalysed detritiation rate constants from the C-16 position of a series of substituted [16-3H]-15,16-dihydrocyclopenta[a]phenanthren-17-ones have been measured in a 90 : 10 (v/v) water-dioxane mixture at 25 °C. The results show that methyl group substitution brings with it, in addition to the customary deactivating effect, a marked acceleration in rate, which probably has its origin in steric strain considerations. Similar studies involving the analogous position in a number of related ketones (benz[e]indanone, indanone, and cyclopentanone) show that the rates are not simply a function of the number of additional benzene rings but depend on their position relative to the cyclopentanone system.
Oral administration of specific yolk antibodies (IgY) may prevent Pseudomonas aeruginosa infections in patients with cystic fibrosis: A phase I feasibility study (2003)

Respiratory infection is the major cause of morbidity and mortality in cystic fibrosis (CF) patients. Chronic Pseudomonas aeruginosa (PA) infections ultimately occur in virtually all patients. It is impossible to eradicate PA when a patient has been chronically colonized. Immunotherapy with specific egg-yolk antibodies (IgY) may be an alternative to antibiotics for the prevention of PA infections. We wanted to determine if treatment with specific IgY can prolong the period between the first and the second PA colonization? And long-term, can the treatment diminish the number of positive PA cultures and postpone the onset of chronic colonization? CF patients gargled daily with an IgY-antibody preparation, purified from eggs of hens immunized with PA bacteria. They were compared to a group of patients who did not gargle with the preparation. Both groups had their first colonization with PA eradicated by antibiotics. The basic treatment was essentially the same in both groups. In the initial study, the period between the first and second colonization with PA was significantly prolonged for the treated vs. the control group (Kaplan-Meier P = 0.015, Breslow test). In the prolonged study, the treated group had only 2.5 sputum cultures positive for PA per 100 months of observation, and none of these patients became chronically colonized with PA. No adverse events were reported. In the control group, 13.7 cultures per 100 months of observation were positive for PA, and 5 (24%) patients became chronically colonized with PA. This feasibility study shows that antipseudomonal IgY has the potential to effectively prevent PA colonization without any severe adverse effects. A phase III study should be initiated.
Down syndrome: characterisation of a case with partial trisomy of chromosome 21 owing to a paternal balanced translocation (15;21) (q26;q22.1) by FISH. (1997)

A patient with a typical Down syndrome (DS) phenotype and a normal karyotype was studied by FISH. Using painting probes, we found that the patient had partial trisomy of chromosome 21 owing to an unbalanced translocation t(15;21) (q26; q22.1) of paternal origin. To correlate genotype with phenotype as accurately as possible, we localised the breakpoint using a contig of YACs from the long arm of chromosome 21 as probes and performed FISH. We ended up with two YACs, the most telomeric giving signal on the der (15) in addition to signal on the normal chromosome 21 and the most centromeric giving signal only on both normal chromosomes 21. From these results we could conclude that the breakpoint must be located within the region encompassing YACs 280B1 and 814C1, most likely near one end of either YAC or between them, since neither YAC814C1 nor 280B1 crossed the breakpoint (most likely between marker D21S304 and marker D21S302) onband 21q22.1. The same study was performed on the chromosomes of the father and of a sister and a brother of the patient; all three carried a balanced translocation between chromosomes 15 and 21 and had a normal phenotype. We also performed a prenatal study using FISH for the sister. The fetus was also a carrier of the balanced translocation.
Leucine kinetics in endurance-trained humans (1990)

This study compared whole-body leucine kinetics in endurance-trained (TRN) and sedentary (SED) control subjects. Eleven men and women (6 TRN, 5 SED) underwent a 6-h primed, constant-rate infusion of L-[1-13C]leucine. Leucine turnover and oxidation were measured using tracer dilution and by measuring 13C enrichment of expired CO2 combined with respiratory calorimetry. Whole-body leucine turnover was greater in the TRN subjects (P less than 0.004; TRN 98.3 +/- 5.0, SED 75.3 +/- 4.2 mumol.kg-1.h-1; mean +/- SE), but there was no difference between groups in leucine oxidation (TRN 13.1 +/- 0.97, SED 11.5 +/- 0.48 mumol.kg-1.h-1). Thus more leucine turnover was available for nonoxidative utilization. In addition, the TRN subjects had higher resting energy expenditures compared with the SED group, and when all subjects were included in the analysis, there was a significant correlation between energy expenditure and protein turnover (n = 11, R = 0.61, P = 0.05). Therefore the heightened resting energy expenditure in the TRN subjects may be accounted for by an increased whole-body protein turnover. These results suggest that endurance training results in increased leucine and/or protein turnover, which may contribute to the increased resting energy expenditure observed in these subjects.
