Abstract We evaluated nasal discs and colored leg bands for Harlequin Ducks (Histrionicus histrionicus) wintering in the Strait of Georgia, British Columbia, by comparing marker visibility and life span, and determining effects of nasal discs on behavior and pairing. Proportions resighted and frequency of sightings were higher for individuals marked with nasal discs than for those marked only with leg bands. Nasal disc loss followed a logistic function that predicted 50% loss by 396 d. Due to wear of leg bands, number of sightings per individual decreased with leg band age following a cubic function. We detected no effects of nasal discs on time spent in various behaviors, timing of pairing, or female pairing success. However, males with nasal discs had lower pairing success, and females with nasal discs were less likely to reunite with previous mates. We speculate that the effect of nasal discs on male pairing success may be due to a male-biased sex ratio and sexual selection on male appearance. Leg band wear should be considered for demographic models because its effects can violate assumptions and bias sighting and survival estimates.


Formaldehyde levels were measured in homes in problem and non-problem areas in Wisconsin and Colorado to elucidate the severity and the extent of formaldehyde emission under field conditions, help correlate laboratory findings with field observations, and investigate the cause and effect relationship between insulation stability and weather conditions of an area. Methods for selecting homes and sampling are described. Interviews were conducted with occupants of the homes and the data are tabulated. Results are summarized. Investigation forms are shown and weather information in Denver and Wisconsin is tabulated. (MCW)

They were kept at 21±1 C° and free access to water and food. There were a control group consisting of 10 rats. Weights of the rats in both groups were measured before and after sudy. The values obtained from both groups were analyzed


To celebrate the centenary of Polish aviation, the profiles of aviators were presented. They were selected on the basis of a review of the professional press of the interwar period. A collective portrait of aviation representatives of that period was prepared for a cognitive purpose. The subject bibliography was elaborated as a source of biographical information. The distinguished common features of the group's representatives made it easier to answer the following questions: who were the Polish aviators during the Partitions period, how they coped with the organization of aviation in independent Poland, during the period of technical imperfections; what were their attitudes towards the necessity of participating in wars.


It has been pointed out by three of the present authors (Y. A., K. S. and K. F.)D that, on the basis of the mechanism remarked by Fritzsch and Minkowski and by Ellis,2l nonleptonic decays of hyperons and K 8 -'72n are well explained by introducing the right-handed current (hereafter abbreviated as RHC) cr p (1r 5) ( -d·sin {} +s· cos{}), and that in case of weak radiative decays of hyperons, the choice of {}::::::. {} c/5 ({}c=Cabibbo angle) leads to a more favourable result than that of {}=0. In case of nonleptonic decays of charmed hadrons, the hadronic current including such RHC in addition to the ordinary left-handed current (LHC)3) leads to various distinctive results4) -s) different from those in the ordinary theory only with LHCY Especially, we obtain the parity-violating (pv) Hamiltonian for nonleptonic decays of charmed hadrons, the dominant part of which belongs to 45+45* of SU(4) 6) and the remaining part of which belongs to 20" + 84 coming from the LHC product. The former part leads to a favourable result about D+-'7K8 n+.6) Further, under a certain prescription of calculating nonleptonic decay amplitudes, our scheme with the RHC seems explainable, at least qualita-

This article proposes a systematic methodology for the development of a problem analysis for cross-sectional, empirical research. This methodology is referred to as the 'Annabel approach'. It is suitable both for academic studies and applied (business) studies. In addition it can be used for both qualitative and quantitative studies. It is argued that the Annabel approach has certain advantages as compared to general approaches to the problem analysis. These include the inherent logic of the problem analysis design, and the inter-dependencies of its components, making it possible to carry out a number of formal consistency checks along the process of creating the problem analysis. Consequently, it is contended that the use of this methodology, being a general methodology for designing and executing methodologically sound and scientifically solid research, may result in higher quality problem analyses, while being more efficient in the creation process.


The design of topside facilities for offshore platforms is subject to many restraints, such as space and weight limitations, the need for selfsufficiency, drilling support, gas utilization, secondary recovery, and environmental regulations, which make the design of these facilities different than that of onshore facilities. While this paper does not provide solutions directly applicable to all platforms, it does document previous solutions and provides conceptual ideas and process alternatives that warrant consideration for future platforms.


During launch, satellite and their equipment are subjected to loads of random nature and with a wide frequency range. Their vibro-acoustic response is an important issue to be analysed, for example for folded solar arrays and antennas. The main issue at low modal density is the modelling combinations engaging air layers, structures and external fluid. Depending on the modal density different methodologies, as FEM, BEM and SEA should be considered. This work focuses on the analysis of different combinations of the methodologies previously stated used in order to characterise the vibro-acoustic response of two rectangular sandwich structure panels isolated and engaging an air layer between them under a diffuse acoustic field. Focusing on the modelling of air layers, different models are proposed. To illustrate the phenomenology described and studied, experimental results from an acoustic test on an ARA-MKIII solar array in folded configuration are presented along with numerical results.

Feature Pyramid Network (FPN) has been widely applied in the task of salient object detection (SOD), which has achieved great performance. However, most existing FPN-based SOD methods still have some limitations, such as insufficient guidance due to gradual dilution of semantic information, excessive computation leading to slow inference speed, and low efficiency of training models. In this paper, we design a novel Gradual Shrinkage and Cyclic Interaction Network (GSCINet) for efficient and accurate SOD, consisting of a Multi-Scale Contextual Attention Module (MSCAM) and an Adjacent Feature Shrinkage and Interaction Module (AFSIM). Specifically, the MSCAM aims at efficiently capturing multi-scale and multi-receptive-field contextual attention information through a series of well-designed convolutions and attention weight matrices of different scales to enhance the performance of initial input features. Subsequently, in AFSIM, we propose a gradual shrinkage structure and introduce a circular interaction mechanism to optimize the compressed features with less calculation cost, thereby enabling fast and accurate inference of salient objects. Extensive experimental results demonstrate the high efficiency and superiority of GSCINet against 17 state-of-the-art (SOTA) saliency detection methods under multiple evaluation metrics.

Abstract The aim of the study was to determine the influence of diets (factor D) and the time period (factor T) during which they were applied on the growth performance and physiological condition (blood plasma hematological and biochemical indicators of stress and immunity) in juvenile sea trout (Salmo trutta; initial body weight approximately 73 g). The diet of the fish that was used prior to the experiment (formulated feed; initial fish sample) was modified as follows: a different formulated feed (group B), mixed feed (feed B + prey fish; group B/N), prey fish exclusively (group N). The fish from group A were given the feed that was used prior to the beginning of the experiment. During the 28-day trial neither factors D nor T influenced absolute or relative fish growth rates. Factor D significantly influenced hematological indicators and leukograms, while the phagocytic index and cidal ability were determined by the time test (factor T). Myeloperoxidase (AMPO) was related significantly with the influence of factors D and T and also with the interaction of D×T. A significant decrease in AMPO was noted after two weeks of the test in groups B, N, and B/N, but after four weeks this indicator did not differ from that confirmed in the initial fish sample. The factors tested influenced stress indicators, i.e., cortisol (D and T) and glucose (D). Significant increases in cortisol (group B) and glucose (groups A, B, and B/N) concentrations were noted after two weeks of the test. After the subsequent two weeks (four weeks of the test) these indicators also stabilized. Sea trout from aquaculture readily accept prey fish; however, changes in diet cause stress reactions such as temporarily reduced immunity. Thus, the procedure for preparing sea trout stocking material for release, which is to change the feed from formulated to natural (live fish), should last approximately four weeks.


Thinopyrum intermedium (Th.intermedium) was analysed by Genomic in situ hybridization (GISH) with the probes of total genomic DNA of Th.elongatum 2n=2x=14,E eE e, Th.bessarabicum 2n=2x=14,E bE b,and Pseudoroegneria strigosa (Ps.strigosa ),2n=4x=28,S tS tS tS t respectively.The results showed that the genome of Th.intermedium consists of two close related genomes similar to the genome of Th.elongatum and Th.bessarabicum and one distant genome similar to Ps.strigosa .Thus Th.intermedium has the genome formula E e tE e tE b tE b tS tS t.


We present a framework for music document retrieval that allows users to retrieve a specified singer's music recordings from an unlabeled database by submitting a fragment of music as a query to the system. Such a framework can be of great use for those wishing to know more about a particular singer but having no idea about what the name of this singer is. In order for the searched documents to be relevant to the query, methods are proposed to compare the similarity between document and query based on the automatic extraction of a singer's voice characteristics from a music recording.


A computer code based on the CG-FFT (conjugate-gradient-fast Fourier transform) is reported for analyzing general metallic periodic screens. It is highly efficient and accurate and is being applied to the analysis and design of broadband polarizers and rotators. All Floquet's harmonics are taken into account in the spectral domain by sampling the Green's function in this domain in periodic lattice, which is the reciprocal of the lattice of the periodic structure to be analyzed. The choice of rooftop functions as basis functions and razor blade functions as testing functions leads to a very suitable scheme for iterative methods. A numerical example illustrating the results of the code is discussed.<<ETX>>


We present active critical coupling compensation by employing the free-carrier absorption for a single-arm silicon microring device when the microring has fabrication error to deviate from critical coupling. It is possible to re-establish the critical coupling for the MOS capacitor microring by applying gate voltage within 10 V when the gap width fabrication error is within the ITRS 90 nm CMOS technology node.


Studies of degradation have verified that the decomposition of some quaternary ammonium salts can begin to be significant at the temperature of about 180 ° C and like most thermoplastics are processed at least around this temperature, the thermal stability of the salt in clay should always be considered. Some salts are more stable than others, being necessary to study the degradation mechanisms of each case. In this work, four quaternary ammonium salts were characterized by differential scanning calorimetry (DSC) and thermogravimetry (TG). The results of DSC and TG showed that the salts based chloride (Cl-) anion begin to degrade at similar temperatures, while the salt based bromide (Br-) anion degrades at higher temperature. Subsequently, a quaternary ammonium salt was chosen to be used in organoclays, depending on its chemical structure and its thermal behavior.

Introduction: Sleep disorders are frequently reported in hemodialysis and peritoneal dialysis patients, but there are no studies investigating the dreams of these patients. This study was an examination of differences in the level of dream anxiety between hemodialysis patients and peritoneal dialysis patients. A comparison of depression and anxiety symptoms, sleep quality, and sleepiness between these 2 groups was also performed. Methods: In this observational, cross-sectional study, 49 hemodialysis patients and 29 peritoneal dialysis patients treated at an outpatient nephrology clinic were enrolled. A sociodemographic data collection form, the Van Dream Anxiety Scale, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and the Beck Depression and Anxiety Inventories were administered, and hemoglobin level and fractional clearance of body water by dialysis (Kt/V urea) were measured. Results: There were no significant differences between the groups in terms of dream anxiety (p=0.517), depression (p=0.889), sleep quality (p=0.221), insomnia severity (p=0.152) or hemoglobin level (p=0.505). Discussion and Conclusion: We did not find any significant difference in the level of depression, anxiety, sleep quality, or insomnia severity between hemodialysis and peritoneal dialysis patients in our study. Similarly, the level of dream anxiety was consistent with these findings.


Subsequent to publication of the account of Keetia in the Flora of Tropical East Africa (Bridson 1991), material of a distinctive new species, with the leaves shiny on both faces, has been collected from three sites on the Kenya coast. The new taxon was collected principally by Quentin Luke (Project Executant of Coastal Forest Conservation Unit (CFCU), a project funded jointly by National Museums of Kenya (NMK) and World Wide Fund for Nature (WWF)) and this species is duly named in his honour. Quoting Mr Luke (personal correspondence) 'The discovery of this species is due entirely to the traditions of the Mjikenda peoples of coastal Kenya. Their customary reverence and protection of their sacred groves or 'Kayas', has meant that till this day, there are patches of natural forest remaining in areas of intense cultivation. This find shows the value and need of assisting the Elders in their efforts to preserve these remnants.' I especially wish to thank Quentin Luke for kindly supplying data on these Kayas, and references to relevant literature; this information is included after the species description.


Initially, public transit developed in response to the need for better urban transportation as the largest urban areas began to grow beyond the limits of pedestrian environment. With the rise of importance of the family car, public transit lost much of its power to guide urban growth. While transit and other considerations remained relevant, road development became increasingly significant as a development incentive. Transit became but a single factor among many in urban area development. The article points out that to assure an effective role in urban development, transit requires a strong integration of urban planning, development, and transit investments. Some key actions are suggested, while recognizing that the presence of good transit service is one of the principal considerations that can favorably affect the development of cities, suburbs, metropolitan areas, and economic and residential growth.


Most of the taxonomic and faunistic work on bdelloid rotifers has been carried out in Europe, especially in German speaking countries (DONNER 1965), with the result that more than half of the global diversity of bdelloids is present in Austria (RICCI & FONTANETO 2007). Records of bdelloids from other continents have been rather occasional (see DE RIDDER & SEGERS 1997, RICCI et al. 2003 and SEGERS 2007 for recent reviews). Even in the Palaearctic region some countries are really underexplored. Turkey is one of them, with only 8 species recorded so far (USTAO LU 2004, KAYA & ALTINDA 2009) out of the 461 known to date globally (SEGERS 2007). Here we report new records of bdelloid rotifers from a faunistic survey carried out in Turkey. Forty-five samples were collected from different habitats such as mosses, lichens, ponds, soil, reservoirs, streams and fungi in Central Anatolia and regions close to the Central Black


The school sports training competition system was discussed in this paper through methods of literature,expert interviews,questionnaire survey,on-the-spot investigation,mathematical statistics and logical analysis.It showed that the school sports training system and the three training network of the professional team under the "whole nation system"were dual modes of operation which has not changed yet.The sports administrative department and the administrative department of education implemented single-track operation pattern,each organization arange the competition managements acts in its own way,resulting in barriers between them.Therefore,it was recommended to establish a professional sports competition administration and a joint meeting system,so that the responsibilities of various departments can be clarified.Separated supervision department and service department,in order to made them to perform their own functions respectively.The forms of sports competition should be reformed so as to make the competition classification and the competition contents more scientific.The construction of laws and regulations should be stressed,and the evaluation system should be perfected.The preferential policy should be formulated to ensure the competition market mechanism operated effectively.Educational department should be responsible for personnel training while sports department responsible for sports competitions.They cooperated with clear responsibilities.

In 1962, Thomas Kuhn wrote "The Structure of Scientific Revolutions" and popularized the concept of "paradigm shift." Kuhn commented that scientific advancement is not evolutionary, but involves "a series of peaceful interludes punctuated by intellectually violent revolutions." It is during these revolutions that "one conceptual world is replaced by another." The presentations of the researchers at this conference represent the shifting paradigm of drug abuse research. The presentations at "40 Years of Drug Abuse" Research" will prompt future researchers to integrate the collective work of distinguished epidemiologists, ethnographers, neurobiologists, pharmacologists, as well as prevention, treatment, services, and policy researchers. As the next generation, we are called to use methods that are both transdisciplinary and translational. A transdisciplinary and translational future will require next generation drug abuse researchers to apply knowledge of basic science to prevention or treatment strategies.


The helicopter rotor field is simulated in hover and forward flight based on Computational Fluid Dynamics(CFD). In hover case only one rotor is simulated with the periodic boundary condition in the rotational coordinate system and the grid is fixed. In the non-lift forward flight case, the total rotor is simulated in inertia coordinate system and the whole grid moves rigidly. The dual-time implicit scheme is applied to simulate the unsteady flowfield on the movement grids. The k – ω turbulence model is employed in order to capture the effects of turbulence. To verify the solver, the flowfield around the Caradonna-Tung rotor is computed. The comparison shows a good agreement between the numerical results and the experimental data.


After the passage of the US National Quantum Initiative Act in December 2018 [1], the National Science Foundation and the White House Office of Science and Technology Policy (WHOSTP) assembled an interagency working group and subsequently facilitated a workshop titled "Key Concepts for Future Quantum Information Science Learners" that focused on identifying core concepts essential for helping pre-college students engage with QIS. The output of this workshop was intended as a starting point for future curricular and educator activities [2-4] aimed at K-12 and beyond. Helping pre-college students learn the QIS Key Concepts could effectively introduce them to the Second Quantum Revolution and inspire them to become future contributors and leaders in the growing field of QIS spanning quantum computing, communication, and sensing.


The goal of this work was to predict the trajectories of blowing lunar regolith (soil) particles when a spacecraft lands on or launches from the Moon. The blown regolith is known to travel at very high velocity and to damage any hardware located nearby on the Moon. It is important to understand the trajectories so we can develop technologies to mitigate the blast effects for the launch and landing zones at a lunar outpost. A mathematical model was implemented in software to predict the trajectory of a single spherical mass acted on by the gas jet from the nozzle of a lunar lander.


____________________________________________________________ With the advancement of the human genome project the determination of the general structure of the human genome approaches its completion. A "working draft" covering 90% of the genomic sequence has already been published [a, 1]. Pharmacogenomic research now has to elucidate the molecular polymorphisms underlying individual phenotypic differences. This knowledge will significantly increase the understanding of individual predispositions to certain diseases, as well as the efficacy and potential adverse effects of certain drugs [2]. The most common genetic variations are single nucleotide polymorphisms (SNPs). A SNP is the occurence of a different nucleotide in different individuals at a given chromosomal position [3]. It is estimated that SNPs account for approximately 90% of the individual genotypic variations [3]. Accordingly, in order to fully exploit the available genomic information, there is a growing demand for reliable, fast, cost effective and highly automated analysis methods for SNP genotyping. SNP genotyping can be addressed by several different methods and technologies. However, many of them do not allow the required sample throughput, or they rely on indirect detection reactions, involving specific nucleic acid labelling or hybridization steps. In contrast, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS) measures directly a physical property of the analyte - its molecular mass. Accordingly, MALDI-TOF MS SNP genotyping is not susceptible to background problems resulting from hybridization based detection reactions. Here we present our MALDI-TOF MS SNP genotyping system that allows fully automated data acquisition and SNP genotyping (Bruker Daltonik, Bremen, Germany). The sample preparation starts with a PCR amplification of a genomic DNA fragment containing the polymorphic site of interest. After a purification step with the genopure magnetic bead system (Bruker Saxonia, Leipzig, Germany), the PCR products are used as templates to generate allele-specific


Over the last year, growth in all the major emerging market regions was surprisingly strong (Table III.1). The already healthy rates observed in 2003 were exceeded, and growth reflected a better balance between external and domestic demand. Indeed, global conditions remained unusually favourable for exports from emerging economies and for capital inflows. Consumer and investor confidence rebounded in all regions. This rapid growth put pressure on many critical resources, such as oil. In sharp contrast to the past, however, higher oil prices did not lead to a marked resurgence of inflation. Interest rates in Asia and elsewhere remained low – in part because currency appreciation pressures may have encouraged monetary policy to be easier than it would otherwise have been.

Introduction: Restless legs syndrome (RLS) is a neurological disorder with a prevalence of about 5-10% of the general population. Its clinical symptom is characterized by uncontrollable, unbearable urges to move the legs, causing chronic sleep deprivation. The iron deficiency has been considered an important contributing factor for RLS [1]. In vivo iron evaluation for RLS has largely utilized T2 (=1/R2). However, other confounding factors such as water contents and diffusion may result in changes in tissue T2. Tissue iron content is known to be more specifically associated with tissue R2(=1/T2). The purpose of this study is two-fold: 1) to determine the sensitivity of R2 mapping method for the detection of the iron deficiency in RLS, and 2) to determine abnormal R2 distribution in the nigrostriatal dopaminergic pathway.


A patient with agenesis of the corpus callosum is reported. Angiographic demonstration of a reduced distance between the inferior sagittal sinus and the internal cerebral vein, and between the pericallosal artery and the internal cerebral vein is assumed to be evidence of agenesis of the corpus callosum.


This article reports the solidification mode,microstructure,and element distribution of phases in 18Mn18 Cr N stainless steels with four kinds of N contents. N content significantly affects the solidification mode and microstructure of 18Mn18 Cr N alloy systems. The solidification mode of 18Mn18 Cr N stainless steels changes from Mode F to A as the N content increases from 0. 07% to0. 72%. Additionally,the microstructure of 18Mn18 Cr N stainless steels changes from ferrite + austenite Widmansttten dual-phase structure to ferrite + austenite dual-phase structure and a single phase of austenite as the N content increases. N content also affects the morphologies of austenitic phases. The lath-like or needle-like austenite phase changes into interdendritic and equiaxed austenite phases with the increase of N content. Ridges are present in interdendritic and equiaxed austenite grains,and the amount of ridges increases as the N content increases. There is a relationship between the ridges and the segregation of Cr,Mn and Fe elements in austenite phases during the solidification process. Moreover,this solidification segregation is retained to room temperature microstructure.


In spring 2009 I co-organized a conference at Concordia University under the banner of ''Curating Difficult Knowledge'' and assembled a subsequent volume by that name, intrigued by the intersection of these terms (Lehrer, Milton, and Patterson 2010). My co-organizers and I had thrown a wide net to explore how the notions of both curating and difficult knowledge spoke to a diversity of sites in which violent pasts are represented in public places. We wanted to draw attention to and map out the range of ''curating''—understood broadly as publically transmitting, mediating, and caring for—taking place in practices outside as well as inside museums, sites that taken together form interlocking webs of meaning making in our broader environments. The contributions to this special issue also travel this shared terrain but illustrate the benefit of turning inwards as well as opening out. They refract a single object of study, the new Canadian Museum for Human Rights, through multiple angles of view, scrutinizing the many overlapping or imbricated ways that a museum institution creates and functions as a communicative environment, and raising questions about the ways the institution undertakes to care for difficult knowledge. It is worth here noting a distinction between the terms imbricated and overlapping, and considering which of them may be more apt: imbricated denotes ''lying lapped over each other in regular order,'' like roof tiles (''Imbricate'' 2014), whereas overlapping suggests more randomness. The extent to which the diverse aspects of museums' meaning-making capacities are regularized, with forethought, control, and overall internal agreement, always bears investigation. The ways in which parts of the museum may work in tension, or even at cross-purposes, belies the totalizing institutions that critics often unconsciously imagine museums to be. This is particularly true when looking at a large and highly politicized national museum project like the Canadian Museum for Human Rights. Numerous curators, researchers, and other staff have passed through this museum project (some remaining) and many significant artists and scholars have served as consultants or contributors, presumably in their own attempts to find a platform from which to speak, to have a voice in (or in conversation with) the political aspirations of this new institution.

This paper proposes a new framework to perform topology optimization. As in the level set methodology, the interface is described as the zero level set of a function. We expand the level set function in a finite Fourier series, and then use the Fourier coefficients as design variables of the optimization problem. We show that every interface can be approximated implicitly by the sum of finitely many Fourier modes. We provide an estimate for the truncation error, which is inversely proportional to the number of Fourier modes. Preliminary results are presented for the constraint design of a short cantilever. The final designs show that topological changes were described by the proposed methodology with a significant reduction in the number of design variables. This is in fact the main advantage: when compared to real domain discretization methods, our approach reduces the number of degrees of freedom necessary to describe the boundary.

Hyaluronidase was first used in human antituberculosis vaccination in 1950 (Salhioli, 1933). From the very first it was possible to see that the addition of hyaluronidase increases remarkably the vaccinating activity of killed tubercle bacilli injected intradermally. Also it was confirmed that their diffusion offered an interesting field of study not only of vaccinating antigens consisting of microbic bodies or of organized structures, but also of extractive antigens, of immune sera and of antibiotic drugs (Salvioli, 1933). The hypothesis that led to the use of a vaccine associated with hyaluronidase, termed diffusing vaccine (V.D.S.*), in anti-tuberculosis vaccination, was the same that about 20 years ago led me to perform intradermal vaccinations with Anatubercolina L petragnani, using a plurifocal method (V.D.S.). The aim of this latter method is to produce a vast tissue process with an adequate dose of vaccine. Anti-tuberculosis vaccination with killed bacilli with the addition of diffusing vaccine aims at vaccinating and protecting the organism by using only one injection of a reduced amount of vaccine. The focus of injection often appears less prominent than with the use of germs without hyaluronidase; it is more extensive, showing that the region of tissue involved in the constitution of the vaccinial focus is greater. As I pointed out many years ago, the vaccinial focus is the essential factor for the creation of resistance against virulent tubercle bacilli produced by a vaccine. Killed tubercle bacilli have been used in V.D.S. vaccination tests for two years. Their vaccinating and protective properties were widely shown in practice in newborn children (Salvioli, 1951a and b) as well as in various experiments in guinea-pigsand dogs. In man V.D.S. vaccination has been predominantly employed in infants, but some older individuals who had no allergy have also been injected. The vaccine was inoculated intradermally into the palmar surface of the forearm and caused no general disturbances.


Polymethyl methacrylate-based stealth and functional nanospheres, specifically designed for the reversible adsorption of oligonucleotides (ODN), were prepared by emulsion polymerization of methyl methacrylate in the presence of an ionic comonomer, namely a quaternary ammonium salt of 2-(dimethylamino)ethyl methacrylate, and a nonionic comonomer, namely a poly(ethylene glycol) methacrylate. The nanosphere size is substantially affected by the amount of both the nonionic and ionic comonomers. By appropriately adjusting the concentrations of the ionic and nonionic comonomers, the quaternary ammonium group and PEG chain surface densities can be finely tuned. Accordingly, a great variety of core-shell-type nanospheres, able to bind ODN and to induce dysopsonic effect, can be obtained. © 2000 John Wiley & Sons, Inc.

Five herbicides, viz. 2.4-D, bromacil, pictoram, San H. 9789 and dicamba were tried individually and in different combinations, 2,4-D at 2.0 kg a.i./hs and dicamba at 5.0 kg a.i./ha controlled the weed for 30 days and picloram at 5.0 kg a.i./ha for six months. Bromacil at 20.0 kg a.../ha gave complete weed-free condition one and a half years after the application. San H. 9789 at 20.0 kg a.i./ha although affected the mor- phology and physiology of the weed, complete weed-free condition was not obtained, Coimbnation of bromacil and picloram was more advantageous for allround control of white horsenettie.


Corresponding author. E-mail: email@example.com Gas hydrates are ice-like combinations of methane and water. The global inventory of gas hydrates appears to be very large. Recent estimates of the total amount of methane contained in the world's gas hydrates range from 1500 to 15,000 gigatonnes of carbon. The amount of carbon in gas hydrates is 2 times larger than that present in all known fossil fuel deposit (coal, oil, and natural gas). It may power the mankind for the next 1,000 years. About 97%~98% of natural gas hydrate distribute in continental slope and continental rise, the rest in permafrost zones of Qilian Mountain and Western Siberia (Jia et al., 2016). In China, the gas hydrate samples were first recovered in Shenhu area, the northern slope of South China Sea, in 2007 (Zhang et al., 2007). In 2008, hydrate samples were found in Qilian Mountain. Recently, hydrate samples were recovered in Dongsha and other areas in the northern South China Sea in 2013 and 2015 (Fig. 1).

Abstract— Endothelium‐dependent relaxation of carotid arteries and changes in levels of cyclic (c)GMP between stroke‐prone spontaneously hypertensive (SHRSP) and Wistar‐Kyoto (WKY) rats have been compared. The concentration‐response curve for acetylcholine (ACh)‐induced relaxation was shifted to the right in carotid arteries from SHRSP. Relaxation responses produced by calcimycin (A 23187) and melittin, both endothelium‐dependent agents, were depressed in carotid arteries from SHRSP. Relaxation responses produced by sodium nitroprusside and 8‐Br‐cGMP were similar to those in strips from WKY. ACh‐induced production of cGMP was significantly decreased in carotid arteries from SHRSP when compared with the level for similarly treated strips from WKY. These results suggest that functional changes in endothelium, but not guanylate cyclase activity or cGMP sensitivity in the carotid arteries, may occur in hypertension. Thus, impaired endothelium‐dependent relaxation in SHRSP may play an important role in hypertensive vascular diseases such as stroke.


The impedance errors remaining after applying the industry standard "open-short," a "pad-open-short," and a "open-short-load" deembedding scheme on a 0.43-nH 20-GHz high-Q single-loop inductor test structure are investigated using real S-parameter data taken up to 50 GHz. Since the latter two deembedding schemes both correct for all parasitic elements of the test structures, they are, at least in principle, error free. The accuracy of the "open-short-load" deembedding scheme, however, critically depends on how well the reactive part of the load resistance is accounted for. This issue makes the more simple "pad-open-short" deembedding scheme an attractive choice because the required split between external and internal capacitances is easy to make, either based on process and layout information or from measurements done on a "pad" dummy structure


Properly ensiled forages and grains are bio-secure when fed to dairy cows.7 Silage management is, therefore, important to dairy health and profitability. Veterinarians offering production medicine consultation to dairy producers must be knowledgeable about ensilage. Pathogens are present in silage regardless of how well it is preserved. Problems that may occur include ensiling forages: 1) too wet, resulting in clostridial fermentation and causing reductions in voluntary feed intake, 2) that deteriorate upon extreme aerobic instability, resulting in growth of Listeria monocytogenes, and causing listeriosis, and 3) too dry, producing aerobic instability problems with molds and mycotoxins.

The present paper investigates the impact of gold price and exchange rates on sensex in India for the period from January 2, 1991 to October 31, 2013 using daily data with the application of unit root test, Johansen cointegration test and Granger causality test have been designed. In other words, this paper investigates the affiliation between three financial variables of gold price, exchange rates and sensex between 1991 and 2013. In recent times, Indian investors are demonstrating uncase in the stock markets due to continuous rising of gold prices on account of no fear and no future loss. Again, exchange rate fluctuations will affect international trades, thus influence the stock market. Johansen cointegration test result indicates that there exists a long-term relationship among the selected variables. Granger causality test result shows that there must be either bidirectional or no causality among the variables.


A novel nutritionally based bait matrix was evaluated under field conditions in New Orleans Louisiana and Poplarville, Mississippi against infestations of the Formosan subterranean termite (Coptotermes formosanus Shiraki)and the Easter subterranean termite (Reticulitermes flavipes (Kollar)). The active ingredients tested, included diflubenzuron, chlorfluazuron and some natural products. The Quarterra interception and baiting system was used to deliver the bait matrix. In New Orleans, LA the test area consisted of 3 buildings and wooden areas within the SRRC campus. A total of 230 stations were installed in the wooden areas spaced 20ft (7.29m) apart and 66 stations around the 3 buildings spaced 15ft (5.47m) apart. In Poplarville, MS 396 stations were installed around 31 houses in 3 different neighborhoods spaced as above. These tests were designed to evaluate the areawide management concept. Temperature, termite activity and bait consumption were measured monthly from October 1999 in NOLA and from July 2000 in Poplarville to the present date. Termite activity stopped in the 2 termite infested buildings in New Orleans within 9 months of bait placement and no activity has been observed for the past 8 months. Evidence of heavy termite mortality was observed in both buildings and wooden areas. The rest of the studies are still in progress.

The present study aimed to optimize the production of Scenedesmus sp. biomass during the phycoremediation process. The biomass productivity was optimized using face centred central composite design (FCCCD) in response surface methodology (RSM) as a function of two independent variables that included wet market wastewater concentrations (A) with a range of 10% to 75% and aeration rate (B) with a range of 0.02 to 4.0 L/min. The results revealed that the highest biomass productivity (73 mg/L/d) and maximum growth rate (1.19 day−1) was achieved with the 64.26% of (A) and 3.08 L/min of (B). The GC-MS composition analysis of the biomass yield extract revealed that the major compounds are hexadecane (25%), glaucine (16.2%), and phytol (8.33%). The presence of these compounds suggests that WMW has the potential to be used as a production medium for Scenedesmus sp. Biomass, which has several applications in the pharmaceutical and chemical industry.


In a perfect system, the amplitude of a sinusoidal signal superimposed on a constant background can be determined from Hadamard sums. The simple computation described here allows us to correct a quadratic nonlinearity in the signal detection. Using this procedure, a commercial rotating‐polarizer ellipsometer could be safely operated with signal levels increased by a factor of 15.


I have experienced psychosis for 20 years. The main symptoms are voices and delusions which interact and reinforce each other. I have written a lot about my illness over the years in a series of autobiograhical books called The Stages of Schizophrenia (Chipmunkapublishing 2007). I have had numerous medications including risperidone and clozapine as well as two years of cognitive behavioural therapy. In 2005 I relapsed and having tried many things already it was decided by my CPN to refer me to a more psychological approach and I quickly was nominated to meet a psychologist at my local (mental) hospital. I was told by the psychologist that I would be referred to group work entitled compassion-focused therapy. I wondered what that meant. It was explained that by developing compassion we can soothe the fear caused by schizophrenia. This has been a lengthy and ongoing process as I shall now describe.

This dissertation presents an investigation of the free stream stagnation temperature variations in the University of Southern Queensland (USQ) hypersonic wind tunnel (designated TUSQ), a short duration wind tunnel operated as a Ludwieg Tube with free piston compression heating. Because the facility is relatively new and because strong disturbances have previously been observed in similar facilities, a study to investigate the thermal characteristics of the hypersonic flow generated by TUSQ was needed.
This study investigates the temporal and spatial thermal characteristics of the hypersonic flow produced in the TUSQ facility and relates these characteristics to the compression and flow discharge processes within the barrel. Quantification of the flow conditions produced in wind tunnels is important. Without such information, it is di�cult to relate wind tunnel results to flight conditions or to perform meaningful computational simulations on the tested configuration. Three different versions of an aspirating thermocouple probe were developed for this work and a thin film heat flux gauge was also tested. Results with the Mach 6 nozzle show that the flow stagnation temperature decreases with time and thermodynamic simulations accurately reflect the majority of the observed
temporal variations when flat plate boundary layer cooling is used to model the heat transfer in the barrel of the facility. Because the flat plate boundary layer
cooling model provides a good match to the measured temperature on the nozzle centre line for the majority of the flow duration, it is concluded that signi�cant mixing must have occurred across the diameter of barrel prior to
ow discharge through the nozzle. Measurements in other facilities have indicated the existence of discrete, large scale thermal disturbance which propagated ahead of the piston and potentially compromised the test flow quality, but no such disturbance were detected at the centre line of the nozzle exit in the present work. The stagnation temperature measurements indicated a core flow region with a
radius of almost 80mm near the start of the test flow. The maximum average spatial gradient of stagnation temperature was registered at about 150 ms after the start of the test
flow and had a value of approximately -0:45K/mm within
the core flow region, indicating an average drop in stagnation temperature of about 20K over the core flow region at this time. Complementary pitot pressure
measurements indicate core flow uniformity to within 2% and a core flow radius of at least 80mm for the majority of the test flow duration of around 200ms.
Mach number profiles deduced from the pitot pressure measurements are likewise uniform with a Mach number of 5.81 � 0.05 for the majority of the test flow duration.
A fully-developed turbulent pipe flow model was developed and stagnation temperature fluctuations in the TUSQ facility were estimated to be around 20 K. Although this value is large compared to results from previous experiments in a gun tunnel facility, the value obtained is consistent with the magnitude of the spatial variation in stagnation temperature within the core region of the nozzle
exit flow at about 150 ms from the start of the flow. Relatively low frequency fluctuations in the stagnation point heat flux were observed and these appeared to correlate with the stagnation pressure fluctuations, but further effort in this area is required in order to resolve stagnation temperature fluctuations due to the turbulent mixing in the barrel.


The EPR-spectral D parameter for a series of aryl-substituted trimethylenemethane (TMM) derivatives 2a–g has been determined in a 2-methyltetrahydrofuran (MTHF) matrix at 77 K. Although the substituent effects on the D parameter are relatively small compared with those of the localized 1,3-diradicals 4, the good correlation between the D values of TMMs 2 and those established for 4 signifies that electronic substituent effects may also be adequately monitored in this way for cross-conjugated triplet species. Thus, the p-NO2 group acts as a spin acceptor, while the p-F substituent behaves as a spin donor. Significant steric effects in the aryl-substituted TMMs 2a–m impose a twisted conformation and, thus, reduce conjugation at the benzyl-radical center and are responsible for the relatively small substituent effects on the D parameter in these TMM triplets. Moreover, good linearity is observed between the AM1/AUHF-calculated spin densities at the benzyl position for the twisted conformation and the experimental D values of the TMM triplet diradicals 2.

Governance refers to the processes and structure used to direct and manage an organisation's operations and
activities. It defines the division of power and establishes
the mechanisms to achieve accountability between owners, managers and stakeholders, and the entity that is the organisation.
Governance helps the organisation focus on the activities which contribute most to its overall objectives and to utilise its resources effectively and ensure they are
managed in the best interests of its principal stakeholders.
This paper examines the evolution of governance, together with some of the issues associated with the practice of governance and stakeholder management. The paper also explores some of the key themes associated with ethics within the governance model.


Several compiler optimizations, such as data flow analysis, the exploitation of instruction-level parallelism (ILP), loop transformations, and memory disambiguation, require programs with reducible control flow graphs. However, not all programs satisfy this property. A new method for transforming irreducible control flow graphs to reducible control flow graphs, called Controlled Node Splitting (CNS), is presented. CNS duplicates nodes of the control flow graph to obtain reducible control flow graphs. CNS results in a minimum number of splits and a minimum number of duplicates. Since the computation time to find the optimal split sequence is large, a heuristic has been developed. The results of this heuristic are close to the optimum. Straightforward application of node splitting resulted in an average code size increase of 235% per procedure of our benchmark programs. CNS with the heuristic limits this increase to only 3%. The impact on the total code size of the complete programs is 13.6% for a straightforward application of node splitting. However, when CNS is used, with the heuristic the average growth in code size of a complete program dramatically reduces to 0.2%


A team of authors, mostly enthusiasts belonging to the Czech Butterfly Conservation Society, produced this work, which is valuable for several groups of users. The books not only give information about butterflies (Lepidoptera: Hesperioidea and Papilionoidea) native to the Czech Republic, but also make general recommendations on conservation. One of the great advantages of this master-piece is the parallel text in both Czech and English, so that the book is suitable both for native nonprofessional entomologists and scientists worldwide. More than half of the two paperback volumes contain information on the 161 species living in Bohemia, Moravia and the Czech part of Silesia, plus a few rare immigrants. The information on each species includes its names (Czech, scientific, German and English), life-size colour photographs, often of both sexes and the ventral surface (only adults, caterpillars are difficult to obtain), a table summarising the number of grid squares in the country with records for four periods (to 1950, 1951-1980, 1981-1994, later), and computed trends in incidence (highly negative numbers in threatened species). Global distribution of each species is described and the detailed distribution in the Czech Republic is accompanied by a grid map differentiating the period when last recorded. The paragraphs on habitat affiliation, host plants, life history and behaviour are of appreciable public interest. The last paragraph – threats and conservation – refers only to the situation in the Czech Republic. Introductory chapters occupy about 100 pages, and the description of survey methods about 50 pages. About three pages are devoted to each species. Results of the distribution mapping (30 pages) reveals the best and least surveyed areas, with 41 out of a total 675 grid squares with no record. The areas that have attracted little interest (close to the state border or far from large cities) are a challenge for the future. I must mention that some squares on the border (I found four) were overlooked by the authors and not classified as either with or without a record. The resulting red list of butterflies of the Czech Republic differs in many respects from previously published lists. The last 130 pages (before the references and index, and again in parallel text) deals with conservation (protection) of butterflies and their environment: the diagnosis of crises, risk factors and conservation needs. Butterflies are regarded as umbrella species for the conservation of many other threatened organisms in habitats in early stages of ecological succession, e.g., rock-steppes, peat bogs, alpine pastures and sand areas. This chapter is relevant to other countries, only the list of species will differ. The suggested conservation methods are non-traditional or heretical. They are based on active habitat management, but not the usual reforestation of damaged (industry-created, mined) areas, but rather the cessation or prevention of artificial reforestation. Spontaneous restoration at minimum cost and prevention of succession by occasional damage e.g. by vehicles and animal pasture are recommended. Such promising processes are partially counteracted by legislation requiring engineered reclamation of the potentially biodiversity sanctuaries. Thus the book is recommended reading, not only for entomologists but also for people involved in landscape ecology, nature conservation etc., including politicians.


There are two principal forms of vibrational optical activity (VOA), an IR form referred to as vibrational circular dichroism (VCD) and Raman form known as Raman optical activity (ROA). This paper reports examples of the application of VCD spectroscopy for the determination of the absolute configuration and conformation of chiral molecules, e.g. cyclic β-lactams. VCD spectroscopy can be applied for the characterization of the conformation of proteins and peptides in solution. VCD based conformational analysis of cyclic peptides is discussed. Examples are the cyclic hexapeptide cyclo(Pro2-Gly-Pro2-Gly) and cyclic peptides comprising β-homoamino acids (trans-2-aminocyclopentane or trans-2-aminocyclohexane carboxylic acid). Structure analysis by VCD of opiate peptides, glycopeptides, peptidomimetics and chiral transition metal complexes are also discussed.


This study examines a secondary level game-based learning curriculum centered on a multi-player 3D game, in which students collaboratively make sense of phenomena related to the behavior of charged particles in electric and magnetic fields. We study the interaction among the students while they enlist resources in the form of the game and curriculum materials that serve as scaffolds for sense-making. Through the consideration of coordination of the perception-conception of resources with actions related to scientific inquiry processes, potential sites for generative conversations were identified. We suggest future directions for the design and study of game-based learning curriculum to foster generative conversations that better shape students' sense-making trajectories.


In the occidental side of Montes de Toledo, mountainous zone where soils do not allow intensive cultivation, the olive grove spreads on al1 the hillsides up to the tops, dotting the flat areas with big or small stains that are often converted into pasture. Inthis way, it becomes in a compensation for the low productivity of the explotations located inthe area. Nevertheless during the last years the olive-growing space has continually los1 profitability to the farmer; also the difficulty un mechanizing some kinds of labours and the small property structure of explotations makes difficult to support it. From the actual sensibility we can assure that it is a piece of great landscape and agrological value thai must be preserved, it must be lavished the necessary steps to continuetheir cultivations. Nowadays it is living uncertainly moments maintaining itself in a precarious 1 balance, and depending on the development of the normative that is included in the revision of ACP (Agricultura1 Common Policy).


The original manuscript (Schaefer et al 2015 New J. Phys. 17 015002) contains three typographical errors that we have corrected below. The scienti fi c results were not affected by the typographical errors and all numerical simulations were carried out using the correct equations. Abstract Stable operation of complex fl ow and transportation networks requires balanced supply and demand. For the operation of electric power grids — due to their increasing fraction of renewable energy sources — a pressing challenge is to fi t the fl uctuations in decentralized supply to the distributed and tempo-rally varying demands. To achieve this goal, common smart grid concepts suggest to collect consumer demand data, centrally evaluate them given current supply and send price information back to customers for them to decide about usage. Besides restrictions regarding cyber security, privacy protection and large required investments, it remains unclear how such central smart grid options guarantee overall stability. Here we propose a Decentral Smart Grid Control, where the price is directly linked to the local grid frequency at each customer. The grid frequency provides all necessary information about the current power balance such that it is suf fi cient to match supply and demand without the need for a centralized IT infrastructure. We analyze the performance and the dynamical stability of the power grid with such a control system. Our results suggest that the proposed Decentral Smart Grid Control is feasible independent of effective measurement delays, if frequencies are averaged over suf fi ciently


Geophysical methods can be helpful in mapping areas of contaminated soil and groundwater. Electrical resistivity (ER) and very low frequency electromagnetic (VLF EM) induction surveys were carried out at a site of shallow hydrocarbon contamination. Previously installed monitoring wells facilitated analysis of water chemistry to enhance interpretation of the geophysical data. The ER and VLF EM data correlate well and were used to map the contaminant plume, which was delineated as an area of high apparent and interval resistivities.

Size selective samplers used in estimating potential inhalation hazard to the worker collect particles according to their aerodynamic size. Calibration of these samplers are generally performed under low humidity conditions even though they may be required to operate in a high humidity atmosphere. A series of experiments using iron oxide and Polystyrene Latex (PSL) aerosols were performed to determine differences in aerodynamic size measured in dry and humid atmospheres. The LASL Spiral Centrifuge Aerosol Spectrometer and a horizontal elutriator were used to measure the differences in aerodynamic size (Dae). Under constant temperature conditions there is no change in Dae for particles as small as 0.312 μm for relative humidities as high as 97%. However, the combination of slight temperature decreases and a humid environment leads to significant changes nil Dae.


Purpose To study isolation and identification of the protein from the fruit of Castanea mollissima Blume and to determine their protection for kidney and anti-tumor effect as well as its mechanism of action.Methods The protein from the extract of Castanea mollissima Blume was identified to be castanin(CAS).The effects of CAS on proliferation of mouse hepatoma cells HepS,S180 mouse sarcoma ascites tumor cells,mouse normal renal cells,thymus cells and spleen cells were detected by MTT colorimetric assay.Also the function of CAS on apoptosis of mouse hepatoma cells HepS was examined by DNA agarose gel electrophoresis.Results CAS can inhibit the proliferation of these tumor cells,and also can significantly promote the growth of normal renal cells,thymus cells and spleen cells,while can induce the apoptosis of mouse hepatoma cells HepS.Conclusion CAS may significantly promote the growth of renal cells and has anti-tumor effects.The mechanism of anti-tumor effects of CAS might be related to the increased immunity function of mice and induced apoptosis.


Detection of spectrum hole is one of the essential criteria of cognitive radio networks which enable cognitive radio users to coexist with licensed users without harmful interference. The radio frequency spectrum is not efficiently allocated among licensed users, which leads to scarcity and dependence of spectrum resource in the modern era. One of the ways to improve the efficiency and utilization of an available frequency spectrum is to share the same spectrum resource among the licensed and unlicensed users. The cognitive radio systems aim to overcome the problem of limited radio frequency spectrum by helping to achieve improved spectral management, utilization, and efficiency. One of the most necessary requirements before performing spectrum sharing is spectrum sensing. There are many spectrum sensing algorithms available for cognitive radio technology. This paper has examined the most suitable detection method under low signal to noise ratio. Hence, a comparative study has been done on the Covariance-based and Cyclostationary feature based detection method in a dense urban area. KeywordsSpectrum Sensing; Covariance-Based Detection; Cyclostationary Feature Detection; Probability of Detection.


Reliability Redundancy Allocation Problem (RRAP) is a major problem in engineering design practices. RRAP includes two major concerns that are specifying the redundancy level and the reliability of each component. The purpose of this approach is to increase reliability level of system by considering related constraints. In this article a multi-objective RRAP comprising of reliability and cost as objective functions is studied. In this study, the discount rate for cost of the components is taken into account. Reliability level of each component is regarded as a triangular fuzzy number as well, and a fuzzy multi-objective optimization problem is developed to handle this issue. Then, the expected value concept is used to convert developed model to a crisp model. Finally, multi-objective particle swarm optimization (MOPSO) is applied to solve the crisp model.

We present a human immunodeficiency virus‐infected patient with severe decompensated hepatitis C virus‐related cirrhosis awaiting liver transplantation (LT) who received a 24‐week course of interferon/ribavirin‐free antiviral treatment with sofosbuvir and daclatasvir on a compassionate basis. Rapid viral suppression was associated with progressive improvement of his liver function tests. The patient achieved a sustained virological response and concomitant clinical improvement, which prompted removal from the LT list 12 weeks after the end of treatment.


Abstract: Rotary desiccant wheel are used to regulate the relative humidity of air streams. These are commonly integrated into heating ,ventilation and air conditioning unit to reduce the relative humidity of incoming ventilation air. Passive ventilation system are able to deliver adequate ventilation air but cannot control the humidity of the incoming air. To overcome this, the honeycomb water structure of rotary desiccant wheel was redesigned. In addition to this, the temperature of the regeneration air for desorption was lowered. Cooling pads were introduced in between the spokes of the wheel and filled with silica gel particles to form a rotary desiccant wheel. Computational fluid dynamics (CFD) model of the design was validated using experimental data.


This paper is concerned with the problem of sampled-data control of a multi-variable system when only one control variable may be used at a time. A quasi-optimal system for time-sharing control is designed via the direct method of Lyapunov. The design specifies control lows and the decision criterion for utilization of the controller. It is shown that even with simplified decision criteria, stability properties are preserved. The method is developed for continuous plants containing at most a single integration. The results also apply to the classical adaptive-sampling problem where the objective is simply to conserve the number of controlling sampling intervals for a single process. A numerical example is presented of the time-shared control of four second-order systems, each containing an integration.


The demand of high performance and low power has increased the importance of power efficiency in multi-core systems. In modern multi-core architectures, DRAM has dominated the power consumption and therefore reordering based DRAM scheduling has been intensively studied to reduce the power. However, the benefit of reordering is not fully explored by the previous studies. To further reduce the power, this paper proposes the read-write reordering and the read-write aware throttling. When compared to the existing work, the proposed techniques reduce 10% more DRAM power with less performance degradation.


Magnetic iron oxide films were successfully deposited on heated fused‐quartz substrates via the plume generated by the excimer laser ablation of poly(ferric methacrylate), an organometallic polymer, in an oxygen atmosphere. The investigation for the deposited films by means of x‐ray photoelectron spectroscopy, Raman spectroscopy, x‐ray diffraction, and scanning electron microscopy demonstrates that these films consist of iron‐rich Fe3O4 and α‐Fe2O3 phases that are made up of ball‐like grains with nanometer‐size structure. Magnetic hysteresis loop of the deposited film was also measured. The values of saturation magnetization, remanence magnetization, and coercivity are 35.6 emu/cm3, 6.13 emu/cm3, and 200 Oe, respectively.

Category: Hindfoot; Midfoot/Forefoot Introduction/Purpose: Adult acquired flatfoot deformity is a complex deformity associated with the collapse of the medial longitudinal arch. Several factors have been proposed in the etiology of adult acquired flatfoot deformity including arthritic, neuromuscular, and traumatic conditions; however, posterior tibial tendon dysfunction remains the most common etiology. A spectrum of conditions affecting the posterior tibial tendon has been identified, with tendinitis occurring early in the disease process and tendon rupture occurring at the more advanced stages. Adult-acquired flatfoot deformity requires a complex operative plan that often utilizes several procedures to correct deformity, at both the hindfoot and midfoot. The objective of this study was to compare the efficacy of two different osteotomies commonly used to correct flexible flat feet. Methods: 42 Patients (21 males and 21 females) with stage II PTTD acquired flexible flatfeet were included with a mean age of 49.62 +- 6.2. Twinty-two patients had medial displacement calcaneal osteotomy (MDCO) while 20 cases had latercal column lenghtening (LCL). Strayer procedure, spring ligament plication and FDL transfer were done in all patients. Pre- and Post-operative clinical assessment was done using AOFAS and FFI questionaire. Six radiographic parameters were analyzed, two in the anteroposterior view ( talo-navicular coverage and talo-calcaneal angle), three in lateral view ( talo- first metatarsus angle, talo- calcaneal angle and calcaneal inclination angle) and tibio-calcanal angle in axial view. Results: At a mean follow up of 12 months, significant improvement in AOFAS and FFI scores in MDCO and LCL groups with no significant difference between both groups. Postoperative significant improvements in all radiographic measurements in both groups. LCL group showed significant better correction in TNC and calcaneal inclination angles when compared to MDCO group. However, MDCO procedure showed significantly better correction in axial tibial calcaneal angle. Both techniques correct the deformity, however cases received LCL has better correction than MDCO cases and less reoperation rate. Conclusion: Reconstructions performed with LCL produced a greater change in the realignment of adult acquired flatfoot, maintained more of their initial correction over time, and were associated with a lower incidence of additional surgery than reconstructions with a MDCO of the calcaneus. However, a higher incidence of degenerative change in the hindfoot was observed in the LCL group. The ability of LCL to correct the deformity in anteroposterior and lateral plan and MDCO in lateral and axial plan suggests that proper osteotomy should be planned according to the existing deformity. Combination of both techniques may be required in certain cases.


This memorandum presents the preliminary results of the effort to investigate the applicability of isotope correlation techniques (ICT), formulated for the LWR system, to the LMFBR fuel cycle. The detailed isotopic compositional changes with burnup developed for the CRBR was utilized as the reference case. This differs from the usual LMFBR design studies in that the core uranium is natural uranium rather than depleted. Nevertheless, the general isotopic behavior should not differ significantly and does allow an initial insight into the expected behavior of isotopic correlations for the LMFBR power systems such as: the U.K. PFR and reprocessing plant; the French Phenix and Superphenix; and the US reference conceptual design studies (CDS) of homogeneous and heterogeneous LMFBR systems as they are developed.


The neutron-induced fission cross section of /sup 241/Pu was measured at an 8-m-long flight path of the CBNM Linac from 50 to 0.01 eV, allowing a direct normalization to the 2200 m/sec reference cross section. The fission reaction rate and the neutron flux were determined simultaneously with surface barrier detectors placed on each side of back-to-back /sup 241/Pu and /sup 10/B layers. The fission cross section was calculated assuming a 1/v behavior of the /sup 10/B(n,..cap alpha..)/sup 7/Li cross section. Several fission and resonance integrals were calculated from the normalized sigma/sub f/ versus energy curve and compared with other results. Also, the 20.44/sup 0/C Westcott factor, g/sub f/, was calculated to be 1.046 +- 0.006.

Hydrogen provides a practical solution to reduce climate crisis causing by utilization of fossil fuels. Underground spaces provides a practical solution to large-scale and long-time of hydrogen storage. This work is motivated to study the influence of different physical mechanisms on the underground storage process, including geomechanical process, hydrogen adsorption on solid phase, hydrogen dissolution in water phase, hydrogen diffusion in water phase, hysteresis (relative permeability and capillary pressure), and capillary trapping. Results show that an obvious difference exists in hydrogen recovery factor with and without all physical mechanisms. Values of hydrogen recovery factor with all physical mechanisms are lower than values without different physical mechanisms. Hydrogen recovery factor without geomechanical process do not show an obvious difference with values with all physical mechanisms. Underground hydrogen storage process in aquifers is not dominated by the geomechanical process. Storage mechanisms, including hydrogen adsorption on solid phase, hydrogen dissolution in water phase, and hydrogen diffusion in water phase, have less influence on the hydrogen storage process. By contract, underground hydrogen storage process in aquifers is dominated by the hysteresis and capillary trapping mechanisms.

 Hydrogen, a clean energy carrier, has attracted lots of interest recently (Pan et al. 2021b, Tarkowski and Uliasz-Misiak 2022). Especially hydrogen utilization provides a practical solution to releasing CO2 emission duo the heavy use of fossil fuels (Li et al. 2021, Li et al. 2023, Tang et al. 2023). Underground geological structures, such as aquifers and depleted petroleum reservoirs, gradually obtain more attention from the scientific community and industry (Delshad et al. 2022). Because they can provide long-time, large-scale, and safe storage spaces for hydrogen, which further promotes the potential possibility of practical hydrogen utilization.
 Some scientific studies have been conducted to test and answer concerns about underground hydrogen storage. Lysyy et al. (2021) examine different storage mediums for underground hydrogen storage. Different storage schemes are conducted within the gas, oil, and water domains. Results show that the final hydrogen recovery factor has a larger value in the gas domain, followed by the oil domain. Withdrawal hydrogen has the worst behavior in the water domain. As for a sensitive study, the effect of the working rate is relatively well studied. But there is still no unanimous conclusion. Kanaani et al. (2022) take three different working rates to compare the difference between hydrogen recovery factor. Results suggest that a larger value of hydrogen recovery factor can be obtained using a higher working rate. Wang et al. (2022) also use three different rates to study the effect of the working rate on hydrogen storage behavior. But the results are different with Kanaani et al. (2022). In this study, compared to using a high working rate, more hydrogen can be produced when a low working rate is adopted. Cushion gas is another common topic discussed in the literature on underground hydrogen storage. Zamehrian and Sedaee (2022) indicate that the utilization of cushion gas mainly affects the hydrogen behavior in the first injection and production cycle. The final hydrogen recovery factor is less affected by the use of cushion gas. Different cushion gases have different behaviors. Results show that when nitrogen is adopted as a cushion gas, more hydrogen can be produced during the first production process compared to CO2 as a cushion gas. Ershadnia et al. (2023) also study the effect of the cushion gas during the underground hydrogen storage process. Results show that the whole cycle of hydrogen production amount can be affected by the use of cushion gas. More hydrogen can be produced when using cushion gas. In this study, CH4 and CO2 are selected as cushion gases. By contrast, choosing CH4 as a cushion gas has better behavior than CO2. Heinemann et al. (2021) mention that the hydrogen recovery factor can be affected by cushion gas. If more cushion gas can be used, less water can be produced. Hagemann et al. (2016) mention that the injection of hydrogen can stimulate the chemical reactivity induced by different microorganisms and bacteria. Ebigbo et al. (2013) address the activity of methanogenic microorganisms that can consume some hydrogen and carbon dioxide due to metabolism, which can change the composition of the hydrogen storage system. In addition, there are also some studies that have also contributed to improving the understanding of the underground hydrogen storage process. Sainz-Garcia et al. (2017) compare the hydrogen storage behavior using different well types. Results reveal that when a horizontal well is used to perform a hydrogen storage cycle, a lower recovery factor can be obtained than a vertical well system. Meanwhile, a horizontal well system reduces hydrogen injection capacity. Alhotan et al. (2023) conduct a sensitive study on permeability heterogeneity. Iglauer (2022) optimum the geological storage depth for structural hydrogen storage. 1000 m depth is finally suggested. Luboń and Tarkowski (2021) analyze the dynamic carbon dioxide and hydrogen injection capacity using a reservoir model from Poland. Results show under the same injection time, the CO2 distribution area is much larger than H2. Also, some experimental measurements are conducted to build an underground hydrogen storage database (Li et al. 2015, Li et al. 2017, Pan et al. 2021a).

Sound emissions from farm machines cause considerable stress on man and environment. Tests were conducted on sound emissions from an air spacing seeder. The sound analysis from a stationary operated implement gave 96 dB at a distance of 3 m. An analysis was made of the noise source, the suction fan. The highest sound intensity was measured at the fan outlet on the right hand side,. Sound emission increases with higher fan rpm´s and the dominant frequency can be traced back to the multiples of PTO rpm´s. Especially the 1.5, 4.5 and 6 rpm-sequences are incited during fan operation. Currently in the research project sponsored by the German Federal Foundation, measures for reducing noise and their transfer to other farm machines are being examined.


The recent development of θ − θ techniques in pulsar scintillometry has opened the door for new high resolution imaging techniques of the scattering medium. By solving the phase retrieval problem and recovering the wavefield from a pulsar dynamic spectrum, the Doppler shift, time delay, and phase offset of individual images can be determined. However, the results of phase retrieval from a single dish are only known up to a constant phase rotation, which introduces extra parameters when doing astrometry using Very Long Baseline Interferometry. We present an extension to previous θ − θ methods using the interferometric visibilities between multiple stations to calibrate the wavefields. When applied to existing data for PSR B0834+06 we measure the effective screen distance and lens orientation with five times greater precision than was possible in previous work.


In pursuit of a more effective electro‐sensor for environmentally hazardous nitro phenols detection at the trace level, we have developed two novel complexes [Ag(μ‐S‐thzt)(Hthzt)(PPh3)]2·2CH3CH2OH (1) and [Hg (thzt)2(o‐phen)](2) based on 2‐thiazoline‐2‐thiol (Hthzt). In complexes 1 and 2, triphenylphosphine and o‐phen were used as co‐ligands, respectively. Both the synthesizedcomplexes have been characterized by single crystal X‐ray diffraction data,UV–vis., infrared, and NMR spectrometry. Geometry around both the metal ion complexes is distorted tetrahedral. Noticeably, in complex 1, the Hthzt acts as a bridging as well as terminal ligand. The intermolecular interaction found in complexes 1 and 2 have been further investigated through Hirshfeld surface analysis. On comparing fluorescence intensities of Hthzt, complex 1, and complex 2, the order of fluorescence behavior was found to be Hthzt > complex 1 > complex 2. The electrochemical performance of both complexes 1 and 2 and their ability to sense 4‐nitrophenol (NP) have been evaluated through modified glassy carbon electrodes and were detected by the differential pulse voltammetry (DPV) and cyclic voltammetry (CV) methods. Based on electrochemical responses, complex 1 shows more effective performance as anelectro‐sensor than complex 2. With a relatively low detection limit of 0.19 μM, great selectivity, and acceptable sensitivity, the complex 1/GCE sensor demonstrated an exceptional linear plot between the oxidation peak current and NP concentration in the ranges of 0.5–500 μM.

Abstract : The radioprotective qualities of the compounds WR 2721 (s-2-(3-aminopropylamino) ethylphosphorothioic acid) and WR 2823 (S-2-(3-Aminopropylamino) amylphosphorothioic acid) were tested in female mice. WR 2721 revealed high effectiveness after prophylactic i.p. application, the DRF (dose reduction factor) being 2.4. The prophylactic application of WR 2823, however, resulted in a DRF of 2.0. WR 2721 has also been tested in mice after combined injuries (whole-body irradiation and open skin wound). The radioprotective effect was nearly as good as after irradiation only, the DRF being 2.3.

Bangladesh is experiencing rapid urbanization in recent decades. Nearly one-third population of the country lives in the urban areas with a high growth rate. The number of urban centres has increased by over five times from 108 in 1974 to 557 in 2013. The unregulated increase of urban centres demands institutional reform, capacity building and resources to make the service agencies responsive and able to cater the increasing demand. Unfortunately, development programmes and the resource allocation scenario over the past years shows a great neglect towards the small and medium towns with over 80% of the total allocation goes to the big cities to maintain the existing infrastructure. As a result, the country has seen a declining urban WASH coverage trend over the past decade. This significantly affects the well-being of the low income people living in the urban areas.
