We are developing an acoustic levitation chamber for measuring adhesion force strengths among biological cells. Our research has four phases. Phase I, presented here, is concerned with the design and construction of a chamber for trapping cell-sized microbubbles with known properties in acoustic standing waves, and examines the theory that describes the standing wave field. A cylindrical chamber has been developed to generate a stable acoustic standing wave field. The pressure field was mapped using a 0.4-mm needle hydrophone, and experiments were performed using 100 micron diameter unencapsulated air bubbles, 9 micron diameter isobutane-filled microbubbles, and 3 micron diameter decafluorobutane (C4F10)-filled microbubbles, confirming that the net radiation force from the standing wave pressure field tends to band the microbubbles at pressure antinodes, in accordance with theory.

We examine how investment possibilities by licensees and nonlicensees affect the two-part licensing contracts offered by an innovator not participating in a homogeneous good oligopolistic market. By undertaking some investments after the decision to accept or reject the licensing contract, licensees and nonlicensees can decrease their marginal production cost. However, the innovation provides a technological headstart in the continuing process of marginal cost improvement. We find that the two-part equilibrium contracts can be of three types: (i) a fixed fee contract such that all firms become licensees; (ii) a fixed fee contract such that the number of licensees is smaller than the number of firms in the market; and, (iii) a contract that specifies a positive royalty rate and a fixed fee such that all firms become licensees.


The town Myslowice is located in the southern mesoregions of the Silesian Upland: KatowiceUpland (341.13) and Jaworzno Hills (341.14). Myslowice terrain has been intensively usedby man for centuries and still is nowadays. This process left permanent signs on the naturalenvironment; the mosaic forms of land use are the effect of this activity, among others. In thetown area contrasts are frequent – direct proximity of various land use forms is observed.Initial characterization of selected contrasts is the aim of this paper. Authors created andemployed the map of land use forms of the town Myslowice.


Alzheimer's disease is the most common type of dementia affecting at least 27 million people. Recent connections have been observed between gut microbiota and brain health, highlighting the connection of the microbiota-gut-brain axis. Moreover, it has been shown that gut microbiota dysbiosis can affect Alzheimer's pathology through the upregulation of NLRP3 inflammasome. Additionally, diet was shown to contribute to either a neural protective role or result in the progression of Alzheimer's disease. The gut microbiota metabolites trimethyl amine oxide and select short-chain fatty acids were found to induce NLRP3 inflammasome recruitment, ultimately resulting in further aggravation of Alzheimer's disease. In this review, we examined the influence the gut microbiota has on Alzheimer's disease progression.


In Knox v. SEIU Local 1000, the United States Supreme Court looked at a rather narrow question concerning what appears to be an unusual fact pattern involving a union's funding of political activity in a state election. In the end, the Court may well have planted the seeds of the undoing of the financial stability of American unions in the future. This paper recounts the constitutional framework and key First Amendment decisions that laid the foundation for Knox. Then it explores Knox and its possible ramifications concerning the doctrine of negative freedom of association for politically involved trade unions in the United States. It also touches upon key issues raised in concurring and dissenting opinions, as they relate to both procedure and the realities of union financial activity.Until recently, it appeared that American law concerning the rights of union dissenters in union shop or agency shop places of employment was relatively settled. With Knox, the United States Supreme Court has upended the equilibrium that has stood since at least the 1970s and has provided a clear invitation to for union dissenters to challenge both the current Hudson notice opt‐out system and the compulsory funding of even collective bargaining.The controversial center of the Court majority's decision focused on the whether an "opt‐in" (versus the prevalent "opt‐out") system of providing for inclusion of individual contributions to political union activities in a First Amendment analysis. Although such analysis had not been undertaken before and it was not raised by any parties on appeal, Justice Alito's opinion took on the issue. This aggressive move and the tone of the Court, in oral arguments and the written decision, signal clear hostility to the union's position. The bottom line is that the Knox majority determines that an opt‐out system used for a special political fund creates an unacceptable risk that the union will use the fees paid by nonmembers "to further political and ideological ends with which they do not agree." The Court further states that in prior cases it had reluctantly accepted "the free‐rider argument as a justification for compelling nonmembers to pay a portion of union dues." While the Court makes a limited holding that an opt‐in scheme is constitutionally required for special political assessments byunions, it clearly signals that extension of the opt‐in doctrine is possible.If Hudson is to be extended to include a broader application of the Knox opt‐in doctrine, there are few good options for unions. However, unions should consider taking proactive approaches, such as voluntarily (1) "unbundling" their economic and political functions altogether, making it so that there can be political trade unions that focus on political activism that are separate from economic trade unions that focus on collective bargaining issues; (2) bifurcating "full members", those with political affiliation, from "economic members", those who only support the core economic functions of the union on behalf of members, while treating them all like members of the same organization with rights to vote and hold certain offices that relate only to economic unionism. Of course, unions could elect a third option – to maintain both political and economic unionism functions but to allow union membership to be fully voluntary, as in right to work states in the USA: However, such an option is unpalatable to most unions and would largely signal defeat.


Type 1 interferons (T1-IFNs) play a major role in antiviral defense. Orthopoxviruses, including those that produce smallpox and mousepox encode a decoy receptor for T1-IFN, the T1-IFN binding protein (T1-IFNbp), which is essential for virulence. We demonstrate that during mousepox, T1-IFNs protects locally in the liver rather than systemically, and that the T1-IFNbp attaches to uninfected cells surrounding infectious foci in the liver to impair their ability to signal interferon, thus facilitating virus spread. Remarkably, this process can be reverted late in infection by treating with antibodies that block the biological function of the T1-IFNbp. Our findings provide insights on how T1-IFNs function in vivo during viral infection, the first evidence on how an immune evasion gene operates in vivo, and unveil a novel mechanism for antibody-mediated antiviral therapy.


Sensing navigational environment represented by navigation marks is an important task for unmanned ships and intelligent navigation systems, and the sensing can be performed by recognizing the images from a camera. In order to improve the image recognition accuracy, this paper combined a contour accentuation algorithm into a multiple scale attention mechanism-based classification model for navigation marks. Experimental results show that the method increases the accuracy of navigation mark classification from 95.98% to 96.53%. Based on the classification model, an intelligent navigation mark recognition system was developed for the Changjiang Nanjing Waterway Bureau, in which the model is deployed and updated by the TensorFlow Serving.

SUMMARY This study was to investigate whether green tea powder can be directly used as a feed additive for broiler production. Arbor Acres male broilers (n = 288) were randomly allocated to 4 dietary treatments consisting of 6 replicates with 12 broilers each in a completely randomized design. The 4 treatments were as follows: basal diet (CON), basal diet with 0.0004% antibiotics (ENBAC), basal diet with 1% green tea powder (GTP), basal diet with 0.0004% antibiotics, and 1% GTP (GTPEN). Broilers with the GTP treatment lowered body weight gain during their early age (days 0–21), but tended to increase the body weight during the late stage (days 21–42) of production. The feed conversion ratio was not changed upon dietary green tea powder supplementation when the whole production period is concerned. The leg muscle was proportionally high and abdominal fat was proportionally low in the GTP group as compared with that in the ENBAC group. The lightness (L*) value, the shear force, and the calcium content of the GTP group were lower in the breast meat as compared with the ENBAC group. A higher redness (a*) value and intramuscular fat content of breast muscle were observed in the GTP group. Dietary GTP supplementation promoted Lactobacillus proliferation, inhibited E. coli proliferation in the ileum and cecum of the broilers during their 28–42 d of age. Green tea powder could be used as feed additive to improve meat color and Lactobacillus proliferation for broiler production.

Fluorinated prolines (FPros) can be exploited in two ways in proteins or peptides [1]. First, they can modulate proline's cis-trans isomerization and its five-membered ring conformation (pucker) due to the stereoelectronic effect of fluorine. Second, they can serve as 19F NMR reporters to probe intermolecular interactions. For this, the conformational bias to proline should be minimal, which can be achieved by judiciously incorporating two fluorines with opposing effects, such as the (3S,4R) F2Pro variant recently reported by us [2]. However, for both applications, it is necessary to gain insight into the preorganizing effect of fluorine and the (residual) conformational bias to proline, both for model compounds and within the actual peptide sequence of interest.
For experimental five-membered ring analysis, current procedures use Karplus relations [3] that connect vicinal scalar couplings to dihedral angles. Unfortunately, the approximate and general nature of state-of-the-art Karplus relations severely limits accuracy, especially in the case of 3JHF couplings, which are particularly important for doubly fluorinated FPro's. Here, we present an alternative means to translate experimental J-couplings into a probability distribution of five-membered ring conformation (pucker) based on an ab initio full energy landscape analysis of FPro model compounds.
In a first step, 901 ring conformations were generated, evenly spaced in the pseudorotation coordinate space [4]. Next, a geometry optimization was performed for each coordinate while constraining the ring pucker. This was done using DFT in Gaussian16, on Ac-FPro-OMe and Ac-FPro-NMe2 model compounds of all β- and/or γ- fluorination patterns. From the resulting energies, a very detailed probability distribution of conformations was obtained. Experimentally measured 1H-1H and 1H-19F scalar couplings from the same model compounds (using PSYCHEDELIC [5]) satisfyingly matched the Boltzmann weighted average of the computed scalar couplings, validating the calculations. The calculated couplings as a function of ring pucker can then be directly compared with experimental coupling data from FPro residues incorporated in peptides, providing a means to accurately evaluate ring pucker in different contexts. Alternatively, we also developed parameterized relations that directly translate the scalar couplings into pseudorotation coordinates rather than individual torsion angles, allowing for through-space effects across the ring to be taken into account. This approach can in principle be applied to any five-membered ring compound.

This article draws on comparative research involving an exploratory and retrospective survey of 498 students in China and 481 in England and follow-up interviews, focusing on their experiences of physical punishment and disciplinary behaviour from mothers and fathers 'while growing up', including how they felt about their experiences and views concerning what might be perceived as 'acceptable' or 'unacceptable' punishments. The emphasis is on the Chinese findings, although the English findings are referred to for comparison and debate. As children, the Chinese students who were surveyed experienced similar types and levels of punishment, although with significant gendered differences echoing traditional Chinese perceptions of 'passive' female and 'active' male. In a similar vein, there also appeared to be greater expectations in relation to educational achievement for boys in China. While most of the Chinese respondents thought the use of physical punishment acceptable for disciplining children, there were indications that this was being questioned and that some wanted change. The UK students, compared to the Chinese, reported lower levels of physical punishment, although the use of punishment to curtail boys' behaviour was in some respects similar. Use of physical punishment was deemed less acceptable by the UK respondents. Copyright. © 2009 John Wiley & Sons, Ltd.


Postpartum tumors of the uterus are of different origin and show a variable dignity. We report the case of a persistent postpartal tumor of the uterus not removable by multiple abrasions and leading to endomyometritis. The tumor produced low levels of β-HCG, is intermediately sensitive to methotrexate and caused strong vaginal bleeding after six months of observation. The sonographic aspect of the lesion was hyperechoic, inhomogenous and Doppler sonography demonstrated increased vascularity inside the tumor. Removal of the suspicious tumor could be achieved only by complete laparoscopic resection of the uterus horn where the tumor was located. The histological diagnosis, unclear after analysis of material gained by multiple abrasions and biopsies, revealed a placental site nodule (PSN), a benign tumor belonging to the family of intermediate trophoblast (IT) tumors.

Tail docking is a common practice on many dairy farms, and is perceived by many farmers to improve cleanliness and enhance milking parlour efficiency. It is a controversial practice attracting increasing scrutiny by the animal welfare community. Scientific studies have been performed to evaluate physiological and behavioural responses to tail docking in preweaned calves and preparturient heifers. The effect of tail docking on animal behaviour, indicators of pain, fly avoidance behaviours, immune responses and circulating plasma cortisol have been reported. Additional studies have been performed to evaluate the effect of tail docking on cleanliness and udder health in lactating dairy cows. The purpose of this paper is to review current research related to tail docking in dairy cattle.


Qinghai Province is an important part of the Qinghai–Tibet Plateau. It is the birthplace of the Yangtze, Yellow, and Lancang (Mekong) Rivers, the recharge area for China's freshwater resources. With different terrains, the temperature, daylight, and precipitation of Qinghai Province are widely variable. Consequently, the topography largely determines the spatial distribution of ecosystem services (ESs) and affects their interaction. Studying the impact of topography on the spatial-temporal evolution of ESs and their interaction is of great significance for land-use planning and the ecological civilization in Qinghai Province. To explore the spatial distribution and evolution characteristics of ESV and trade-offs/synergies among ESs in Qinghai Province, we considered topography (elevation, slope, RDLS, and terrain niche index) in 1980, 1990, 2000, 2010, and 2020 using the ArcGIS software and the equivalent factor method. The results were then corrected using various parameters. The results showed that the ESV of Qinghai Province decreased from 129,573.99 million USD in 1980 to 129,155.85 million USD in 2000, and then increased rapidly to 142,682.97 million USD in 2020. The spatial distribution of ESV is characterized by high in the south and east and low in the northwest. The geographical distribution and temporal variation of ESV and trade-offs/synergies of ES pairs show distinct vertical zonality, and the relationship between ESs showed different patterns on different topographic gradients. Hence, priority should be given to the ecological protection of high-altitude areas, and the implementation of ecological migration continued. The implementation of protection measures considering the ecological conditions under different topographic gradients can ensure more appropriate ecosystem management and more sensible decision-making.


The author investigates the issues of the culture development management. The author insists that the subject-subject approach needs to be applied in the culture management. Due to the fact that culture is a complex system and management is a dynamic process, the culture management requires respecting of the processes of self-organization. The author suggests an approach in which the culture management is considered to be a process of mass communication. It's determined by the fact that many processes in culture management go in a latent way.


We investigated tree diversity of single- and mixed species-dominated tropical dry evergreen forests on the Coromandel coast of peninsular India and compared these forests with other monodominant forests of the tropical world. For this we established three 1- ha plots one each in three monodominant sites (Suryanpet- SP; Velleripet- VP; S. Pudhoor- SPD) and a 1- ha plot in a mixed species dominant site (Chinna Kumatti- CK). All trees ≥ 10 cm girth at breast height were enumerated. Dominance of a single species in the monodominant sites did not affect total tree diversity of these sites. Tree species richness totaled 56 species in four forests and ranged from 18 (at VP site) to 27 species ha -1 (at CK site). Tree density ranged from 771 (SP site) to 1285 trees ha -1 (CK site). Among the monodominant sites, Tricalysia sphaerocarpa formed 72 % of the forest stand density at SPD, Strychnos nux-vomica 67 % at VP and Dimorphocalyx glabellus accounted for 60.8 % of the total density at SP. A literature survey on the monodominant forests across the tropics revealed that a single tree species could account for 50 to 100 % of stand density in Asian, 58 to 100 % in African and 51 to 91 % in Neotropical forests. The monodominant tree species mostly belonged to Caesalpiniaceae in Africa and Neotropics, and Dipterocarpaceae and Lauraceae in Asia, while Rubiaceae, Loganiaceae and Euphorbiaceae contributed the monodominant species on our sites. As tropical dry evergreen forests of peninsular India still remain understudied, the need for conservation of both mono- and mixed species forests is emphasized.


Abstract : The extreme strain, strain rate and temperature gradients during Friction Stir Processing (FSP) render measurement of key parameters in the stir zone infeasible with common methods. The objective of this research was to separate the effects that temperature and deformation in an experimental study of the microstructure and mechanical properties of Ni-AL bronze (NAB). This was accomplished by subjecting as-cast NAB material to several isothermal annealing and quenching treatments as well as isothermal hot rolling processes. Sufficient material was generated to provide results and data for subsequent optical microscopy, tensile, & hardness tests. All results were then compared to similar data collected from previous works completed here at Naval Postgraduate School and with other DARPA FSP program participants. During the course of this work correlations were drawn between FSP material and the material subjected to isothermal hotworking, which may enhance our understanding of the roles that various FSP process parameters have on the microstructural transformation sequence within this material. The hot-rolling study conducted here suggests that FSP process parameters leading to severe deformation at temperatures between 950-1000 C in the NAB material provides high ductility (elongation approximately 28%) with moderate strengths.


A mean-variance equilibrium model is tested against data from the Italian bond market. General equilibrium models under uncertainty were first constructed by Allais [1] and Arrow [2]. The model tested is of the class formulated by Borch [3], on the basis of works by Markowitz [8] and Tobin [18], and developed further by Sharpe [17], Lintner [6] and Mossin [10]. The bonds used in the test are annuity bonds. These are bearer bonds in loans, where the loan is repaid by a constant amount per period in cover of repayment of capital and interest on the loan. A lottery is arranged before each payment date, in order to determine which bonds shall be redeemed by the forthcoming repayment of capital. The bonds not drawn for redemption then participate in the next lottery, which is held one period later. A sequence of such lotteries is arranged, until all bonds in the loan have been redeemed, and the full amount of capital in the loan has been repaid. An annuity bond thus has an uncertain maturity. Its probability of redemption on a future date is given by the repayment plan for the capital of the loan. The certainty alternative which is considered relevant to the investors is investment in Government bonds. With the market for Government bonds assumed to be in equilibrium, this property is used to take account of the time dimension of investment in the annuity bonds. The investors are then assumed to behave in accordance with the von Neumann and Morgenstern theory [11], and establish preferences over probability distributions of present wealth. Such a behavioural assumption was tested earlier in an experiment [15], and gives a reasonable description of investor behaviour. Italian data were chosen, because investors paid no taxes on income from capital gains and interest payments during the period studied.


Experimental results of detailed measurements of periodic surface damage induced by pulses from a Nd:YAG laser radiation on surface of Ge samples and Ge films on SiC>2 subs trate are reported. The periodic surface structures or ripples are created by the inten sity modulation on the surface which is the result of the interference of incident laser beam and a coherently scattered surface waves (surface plasmons, grazing transversal wa ves, surface polaritons), which may be generated by photons at a rough surface. We consi der a dependence of ripples growth rate from direction of incident light polarization, form of the laser spot, direction of surface wave travelling. The coherent extension of ripples from overlapping laser spots was observed for the grating with spasing d=-ft/cos6 where 6 is angle of incidence of laser beam, Jt is wavelength of light. The optical gra ting with square near 2 cm2 was manufactured.


The initial mode of investigation of suprarenal masses often depends on which clinical department the patient enters on admission to the hospital. Characteristic clinical manifestations frequently channel the patient into certain clinics. The claim has often been made that abnormalities of the adrenal can be diagnosed in a definite fashion on the basis of endocrinologic studies, but the group of lesions in the suprarenal area include a large number of "tumors" devoid of endocrine manifestations (1, 16, 34, 43, 45, 48, 57, 61). In these instances, the topographic localization of the tumor and often a near histologically accurate diagnosis can be made on the basis of various roentgenographic examinations (2–4, 8, 14, 17, 22, 23, 28, 29, 34, 38–40, 51, 59, 60, 62, 66). This communication attempts to prove the diagnostic value and reliability of various special roentgenographic studies in a series of 161 patients examined and diagnosed by this battery of procedures.

Maria Ondina Braga (1922-2003), a Portuguese itinerant and contemporary writer, frequently calls upon the themes of travel and otherness for her literary aesthetics. Alongside these thematic lines, the work under study, Estátua de Sal (1983), constitutes a novelized autobiography where Ondina Braga's biographical experience is fictionalized, literalized and, above all, self-analyzed. This article, focusing exclusively on the aforementioned work, intends the following: (i) to review aspects of literary theory by framing, on the one hand, specificities of the writing of the I in Maria Ondina Braga and, on the other hand, by generically presenting the work; (ii) then, two main objectives. The first is to problematize the architecture of memory, or to put it differently, the way memory is structured in the space of narration and shared with the reader; the second aspect is related to the achievement of a first analysis of the selected textual excerpts; in a third moment, the exercise explores the revisitation and the sharing of the inner world of the character in the light of a line of reading that understands writing as a space of denunciation and criticism of social and cultural vectors.


Background: Immediate implant placement in the maxillary anterior region was challenging, especially with the jumping gap and limited primary implant stability. Objective: To assess the autogenous dentin graft biomaterial's ability to improve the esthetic outcomes of an immediately inserted implant. Methods: Twenty patients with non-restorable retained roots in the maxillary non-molar region surrounded by natural sound teeth were included in this study after a complete clinical and radiological examination, including patient health and clinical fitness for the immediate dental implant procedure. A single dental implant was inserted for each patient, and the resulting jump distance was filled with the mineralized dentin graft and covered by gel foam with the figure of eight suturing. The Pink Esthetic Score index of the implant-supported prostheses was evaluated six months after the initial surgery. Results: Twenty eligible patients were included in this study. The assessment of the clinical measurements of the alveolar ridge width and gingival biotype before surgical intervention and after 6 months showed no significant differences between them. The mean Pink Esthetic Score (PES) was 7.75. Only two patients achieved a total esthetic score of 10; another three patients had a score of 8, four with a score of 7, and the rest with a score of 6. Conclusion: An autogenous dentine graft effectively achieves acceptable esthetic results with an isolated immediate dental implant inserted in the anterior maxillary area.


Summary form only given. We present detailed measurements of the implosion and X-ray emission mechanisms of radial wire array z-pinches - array configurations where the wires stretch radially outwards from a central cathode. Initially the wires ablate, then an implosion begins, starting close to the cathode where the global magnetic field is highest. Implosion continues as bubbles of plasma being accelerated above the cathode where they collide forming a highly emitting column. In the radial configuration emission from the snow-ploughing of ablated plasma can be more easily separated from that of the stagnating plasma column than in standard cylindrical wire arrays, allowing the different physical processes that determine emission to be examined. The scaling of power and yield with array configuration is explored in order to test whether radial arrays can provide a compact source for the energisation of small scale hohlraums on larger facilities. In addition to fine metallic wires, solid metal foils have also been imploded. The gross dynamics of foil experiments are similar to those with wires - with plasma first being observed to be ablated from the foil and then an implosion and stagnation occurring close to the cathode. Differences in the use of foils and arrays will be highlighted, and current stratification explored.

Seizing the opportunity" is an idea of the most importance in Deng Xiao - ping theory. From the angle of economy philosophy, the article clarifies philosophy base and precondition of this idea. And point out: for quickening economic development, we need not only the spirit of immersing oneself in hard work, but also the capacity of seizing the opportunity.


Immersive videos, also known as 360° videos or spherical videos, are videos created with a panorama that records in all directions at the same time. In this work of educational innovation, we measure the effectiveness of the use of 360° videos in education. We apply a series of learning activities so that students relate real-life actions with the contents of the course. The students watched 360° videos with virtual reality lenses in the classroom and made the didactic sequence prepared for each activity. We measure the degree of acceptance of this innovative didactic resource by students as a learning tool. The students who used the immersive technology of the 360° videos recorded in scenarios related to their professional environment obtain a greater knowledge of their future professional life through the content of the video, they have a greater feeling of illusion of place, positive affection and a greater enjoyment of the topic that is covered in the 360° video. As a result of the activity, we conclude that the use of 360° videos in education are very effective and its use will be an important trend in the coming years.

We consider the problem of learning a classifier from observed functional data. Here, each data-point takes the form of a single time-series and contains numerous features. Assuming that each such series comes with a binary label, the problem of learning to predict the label of a new coming time-series is considered. Hereto, the notion of {\em margin} underlying the classical support vector machine is extended to the continuous version for such data. The longitudinal support vector machine is also a convex optimization problem and its dual form is derived as well. Empirical results for specified cases with significance tests indicate the efficacy of this innovative algorithm for analyzing such long-term multivariate data.


Future wireless communication demand high data rates, low latency, high accuracy, better quality of service and much more. These demands raise challenges in wireless communication system because signal is traveling through medium where signal quality is degraded by random fades, diffraction, noise and other performance reducing phenomenon. To meet the demands, we need technological advancements, so we can alleviate these challenges. NOMA is emerging technique of 5G that ensures better performance than traditional multiple access techniques. In a typical NOMA system, users individually communicate with base station and treat any other user signal as noise. Here the important point is that NOMA strong users have information of all weak users. In this paper, we propose a novel hybrid cooperative communication scheme for multiuser power domain NOMA based on amplify-and-forward (AF) and decode-and-forward (DF) over strong user to improve performance of weak user in cellular system. We exploited the key feature of NOMA that states that strong user has prior knowledge of weak user with bad channel condition. Strong user is used as relay to improve performance of weak user via cooperative communication. BER Curves analysis proved that performance of weak user laying over the edge in cellular system can be improved via cooperative communication.


Reaction of a 1:1 mixture of penicillin N and 2,2-bis(trideuteriomethyl)penicillin N with partially purified deacetoxy-cephalosporin C/deacetylcephalosporin C synthetase from Cephalosporium acremonium CO 728 resulted in preferential conversion of the protiated substrate, whereas in similar experiments with a 1:1 mixture of penicillin N and 3-deuteriopenicillin N both substrates were converted at the same rate; these results accord with a stepwise process for hydrogen removal during the ring expansion in which the methyl hydrogen is first removed.


To solve the problem of the high cost in the GPRS communication and the limit transmission distance of WiFi, a transmission scheme for distant agriculture image acquisition was designed based on digital transmission radio in this paper. However, the majority of current digital transmission radio was designed for a small amount of data transmission. It could get a greater transmission distance with the help of the digital transmission radio, but the signal interference increased heavily when the digital transmission radio was used for image transmission. A fault-tolerant transmission protocol for agriculture image (FTTP-AI) based on digital transmission radio was designed in this paper. Packet verification was used to reduce the data errors caused by the signal interference of the digital transmission radio. At the same time, overtime retransmission and the lost packet retransmission were used to overcome the problem of packet loss. Experiments showed that the FTTP-AI could send the agriculture image to a remote computer center successfully in the field. With the help of the FTTP-AI, the rate of accuracy of data transmission was up to 99.2%, the success rate of image transmission was up to 95.8%, the costless distant transmission can achieve several kilometers. This scheme could satisfy the requirement of the low-cost for distant agriculture images transmission reliably.


The utility model relates to a high temperature-resistant conveying belt canvas. The high temperature-resistant conveying belt canvas comprises a warp-wise protection upper layer, a warp-wise reinforcing middle payer, a warp-wise protection lower layer and weft-wise structure layers, wherein the warp-wise reinforcing middle payer is positioned between the warp-wise protection upper layer and the warp-wise protection lower layer; the weft-wise structure layers are tightly inserted into the warp-wise protection upper layer, the warp-wise reinforcing middle payer and the warp-wise protection lower layer in a penetrating way. The canvas provided by the utility model is of a layered structure, so that penetration of impregnation and rubberizing is facilitated, and the adhesion effect between the canvas and the rubberizing can be effectively enhanced.

adult volunteers,' who breathed into a closed system with a recording spirometer, that, when the manoeuvre was applied, the peak expiratory flow rate obtained was 205 litres/minute with 940 ml of air expelled during the early expiratory phase, at a pressure of 4.1 kPa (mean values). The effect of the manoeuvre was studied in anaesthetised beagles7 when each application caused 120 ml to be ejected (the animal's normal tidal volume). However, in beagles paralysed with tubocurarine, the volume exchange decreased to levels of 20 to 40 ml within 30 seconds of repeated applications. Heimlich theorised that the paralysed diaphragm is unable to descend to its original position in these circumstances and results in a reduction of the air volume after each application of the manoeuvre. It is possible that, in this patient with hemiplegia and reduced lung volume, diaphragmatic incompetence resulted in a rapid and progressive decrease in thoracic volume, which prevented the generation of sufficient airway pressure to dislodge the partial laryngeal obstruction. This case highlights that all that is swallowed at meal times is not necessarily food and it demonstrates the likelihood of failure of the Heimlich manoeuvre in patients with reduced thoracic volume and diaphragmatic incompetence.

Naturally accumulated doses after pottery manufacture were compared between optically stimulated luminescence (OSL) from quartz grains and infrared-stimulated luminescence (IRSL) from feldspar grains, together with a red-thermoluminescence (RTL) result from quartz grains. Quartz and feldspar extracts from nine Jomon pottery pieces, which were manufactured and used 3,500-6,000 years ago, were subjected to three kinds of luminescence measurements using a new automated luminescence measuring system. Since this system included a small X-ray irradiator, a single-aliquot regenerative-dose (SAR) protocol was applicable to each luminescence dosimetry. Naturally accumulated doses from RTL were higher than OSL- and IRSL-dose results. This is probably due to relatively easy-bleaching effects or unstable luminescence properties related to the OSL in quartz grains and well-known anomalous fading effects of feldspar grains. On the basis of these results, the RTL-luminescence ages, estimated using the accumulated doses and annual doses, are closer to the predicted archaeological ages. In conclusion, it was also confirmed here that the RTL-dating is most suitable dating-method when quartz extracts from burnt archaeological materials are available.


Medullary carcinoma of the thyroid occurred in a young girl with an unusual facies, neuromas of the lips and tongue, bilateral pes cavus and a slipped capital femoral epiphysis. These abnormalities may rep resent the phenotypic manifestations of a single gene. Patients with this type of face and lips or any of the other findings should be followed carefully for the presence of thyroid and adrenal tumors.


Methods. PhSeZnCl was encapsulated in poly(D-L-Lactide) (PLA) polymer by spray-drying with a Buchi B290 spray-dryer; likewise, PhSeZnCl powder was also spray-dried without the excipient. The MP were characterized in terms of size distribution with an accusizer C770, encapsulation efficiency by UV-vis spectrophotometry and morphology by SEM. The MP were tested on iMEFS (WT-KO) cells incubated in standard conditions (37°C, 5% CO2, DMEM) for 5 and 24 hours and were analyzed for cytotoxicity by MTT assay and morphology by fluorescence microscopy. For this purpose the MP were labeled with FITC.


Abstract We show that if A and C are torsion-free abelian groups with ∩{ker f|f: A → C} = 0 = ∩{ker g|g: C → A}, and if A has a left Artinian quasi-endomorphism ring then A and C share a nonzero quasi-summand. Some consequences explored.


We have measured the kinetic energy distributions for the mutual neutralization of a large ensemble of atomic anions and cations. Ions are accelerated to equal velocities in a merged beam setup, enabling measurements at collision energies as low as 5 meV. Three-dimensional momentum imaging is performed with two position sensitive detectors located several meters downstream from the few centimeter long region where the beams overlap. An unprecedented resolution in the kinetic energy release (KER) spectra allows us to identify the states of both reactants and products down to their fine structure. Knowing the angular distribution of the products in the laboratory and center-of-mass frame, allows for total, partial, and differential cross sections to be retrieved.


This paper describes classification and prediction for pharmacologically active classes of drugs under the presence of noise chemical compounds. Dopamine D1 receptor agonists (63 compounds), antagonists (169 compounds) and other drugs (696 compounds) were used for the work. Each drug molecule was characterized with Topological Fragment Spectra (TFS) reported by the authors. TFS-based artificial neural network (TFS/ANN) and support vector machine (TFS/SVM) were employed and evaluated for their classification and prediction abilities. It was concluded that the TFS/SVM works better than TFS/ANN in both the training and the prediction.


Aim:To explore the association of the expression of FoxO1 in liver with glycolipid metabolism in high-fat diet obese rats.Methods:Thirty male SD rats were randomly divided into 2 groups by taking routine(n=10) and high-fat diet(n=20).Levels of fasting blood glucose(FBG),serum insulin(Ins),triglyceride(TG),total cholesterol(TC),high density lipoprotein-C(HDL-C) and low density lipoprotein-C(LDL-C) were measured 10 weeks later.Insulin resistance was assessed by HOMA-IR.The FoxO1 mRNA expression level in liver was detected by real-time quantitative RT-PCR.Results:Levels of FBG,Ins,TG,TC,LDL-C and HOMA-IR were significantly higher in obese group than those in control group 10 weeks later(t=1.952,25.566,8.642,5.845,9.922,23.234,P0.05).The mRNA level of FoxO1 in liver of obese group(35.6±4.4) was higher compared with control group(19.3±5.1)(t=8.649,P0.001).The expression level of FoxO1 mRNA in liver was positively correlated with FBG(r=0.565,P=0.004),Ins(r=0.564,P=0.004),TG(r=0.626,P=0.001) and HOMA-IR(r=0.578,P=0.003).Conclusion:The increased expression of FoxO1 in liver of high-fat diet obese rats is associated with blood glucose and lipid levels.FoxO1 may be related to obesity and insulin resistance.


The results from several recent studies suggest that police stop rates are elevated in neighborhoods that are gentrified or undergoing gentrification. However, it remains unclear how these findings fit into the well-documented pattern of racialized proactive policing practices, often interpreted through a racial-threat lens. To further our understanding of how of law enforcement relates to gentrification as a racialized institution, I utilize pedestrian stop data from eight cities to analyze the interconnected relationships between neighborhood-level police stops, temporal changes in racial and ethnic composition, and gentrification processes. Results from negative binomial spatial-durbin models reveal that, controlling for local crime levels and other covariates, police stops are more prevalent in neighborhoods that have experienced decreases in black and Latinx populations and in those surrounding gentrified areas. However, because gentrified and gentrifying neighborhoods have experienced relatively larger losses of these minority residents, this relationship appears to be intertwined with processes of urban revitalization. Based on these results, I argue that the geographic concentration of proactive police stops operates as an instrument of urban social transformation, shaped by racial territoriality – the implicit and explicit claims of whites to urban spaces.


Active Management of labor have accelerated the labor both in primi and multi gravidae cases which is a boom to a lady in labor, it was also noticed that amniotomy and pitocin drip was more effective in multi gravidae than in primi cases. Active management has helped in acceleration of labour by 77.59% and 77.78% in primi and multigravidae respectively.


The experiment of Laird, Taylor, and Wille (1932) showed that the reduction in the intensity of a sound required to produce half‐loudness is of the order of 20 db. Since this result is out of line with most other studies in this field, an attempt was made to repeat the experiment with a similar piece of apparatus (2‐A audiometer). The first attempt to copy the procedure of Laird, Taylor, and Wille gave results more like those usually obtained, namely, a required reduction for half‐loudness of the order of 10 db. A second experiment, involving the use of comparison tones placed as much as 40 db below the standard, gave results more like those of Laird, Taylor, and Wille. The method they used appears to be overly sensitive to the range and order of presentation of the comparison stimuli.


Aim: To compare the occurrence of neurological soft signs (NSS) in children with specific developmental disorders of scholastic skills (SDDSS) and normal children. Methods: 36 cases of SDDSS were compared with 30 control children regarding sociodemographic and clinical variables and neurological soft signs. Results: Children with SDDSS had significantly more problems in graphaesthesia, motor task, face-hand and face-noise test, 2-point discrimination, maintenance of posture, and rhythmic movements. Conclusions: Children with SDDSS had more NSS in the form of impaired motor task, poorly developed cortical sensory perception and poor body and space concepts. However, the presence of co-morbid hyperkinetic disorder in a large number of SDDSS subjects might have confounded the result.


In response to NO{sub x} reductions mandated under Title I of the 1990 Clean Air Act Amendments (CAAA), Public Service Electric & Gas and Atlantic Electric of New Jersey evaluated Selective Non-Catalytic Reduction (SNCR) for NO{sub x} control under separate programs at Mercer Station and B.L. England Station, respectively. Mercer Station is comprised of twin 321 MW Foster Wheeler coal-fired wet bottom boilers, with natural gas capability up to 100% load. B.L. England Station has three units, two of which are cyclone boilers of 136 MW and 163 MW. These furnace designs are of particular interest in that nominally 23,000 MW of cyclone boiler capacity and 6,900 MW of wall- or turbo-fired wet bottom boiler capacity will be faced with NO{sub x} reductions to be mandated under Title IV - Phase II for Group II boilers. Both stations evaluated Nalco Fuel Tech`s SNCR system using a portable test skid, with urea as the reducing chemical. The Mercer Unit 2 demonstration was performed with a low sulfur coal (nominally 0.8%), while the B.L. England Unit 1 demonstration utilized a medium sulfur coal (nominally 2.4%), and also re-injects fly ash back into the cyclones for ultimate collection and removal as slag. Tomore » address concerns over potential Ljungstrom air heater fouling, due to reactions between ammonia and SO{sub 3} in the air heater, and fly ash salability at Mercer Station, both sites targeted no greater than 5-10 ppmv ammonia emissions at the economizer exit. At Mercer Unit 2, air heater fouling was only experienced during system start-up when the ammonia emissions at the economizer exit were estimated at levels approaching 60 ppmv. B.L. England Unit 1, however, experienced frequent fouling of the air heater. NO{sub x} reductions achieved at both sites ranged between 30%-40% from nominal baseline NO{sub x} levels of 1.1-1.6 lb/MMBtu. Each site is currently undergoing installation of commercial SNCR systems.« less


A brief theory of wavelet transforms and their effective computation method with an emphasis on the considerations of the choice of pressure angle are presented in this paper. This is followed by the numerical results with related graphs. The procedure used in this paper include the numerical simulation of the dynamics of a gear transmission system. Important advancements in preventive maintenance of gear transmission systems are currently being sought for the development of an accurate machine health diagnostic system. Such a diagnostic system should use vibration or acoustic signals derived directly from the gear transmission. Finally, the improvement of the kinematical quality of gear transmission was tested by means of the Wavelet Transform. Key-Words: Spur gear, Discrete Wavelet Transform, numerical simulation, gear transmission, kinematical quality, mechanical diagnostics.


Summary In this paper we introduce some new definitions for sequences of operations and extract general theorems about properties of iterative algorithms encoded in nominative data language [20] in the Mizar system [3], [1] in order to simplify the process of proving algorithms in the future. This paper continues verification of algorithms [10], [13], [12], [14] written in terms of simple-named complex-valued nominative data [6], [8], [18], [11], [15], [16]. The validity of the algorithm is presented in terms of semantic Floyd-Hoare triples over such data [9]. Proofs of the correctness are based on an inference system for an extended Floyd-Hoare logic [2], [4] with partial pre- and postconditions [17], [19], [7], [5].


There has been a growth of interest in 'holistic' approaches to the study of media communication over the recent period, in which analyses of media consumption and production have become more closely integrated. In welcoming this trend, this article identifies the basis for this integration and considers the negative consequences of any continued dissociation of production and consumption debates. It is also noted that tensions still remain between perspectives, and the article concludes by considering one of the main contemporary areas of dispute: how the political realm should be conceptualized and, as a consequence, what should be seen to count as political communication. A model is then outlined that seeks to integrate positions that have hitherto been cast as opposed.


The New Consensus approach in macroeconomics is criticised for its exclusive but unwarranted reliance on stabilising monetary policies, for its ill-designed approach to the role of wages and wage policies, and for its complete neglect of fiscal policies. From a Post-Keynesian perspective, it is argued that fiscal policies play an important role for macroeconomic development, albeit the whole macroeconomic policy-mix of monetary, fiscal and wage policies as well as open economy conditions should be considered. Based on this view macroeconomic performance and macroeconomic policies in France, Germany, Sweden and the UK between 1996 and 2005 are analysed, with a special focus on the role of fiscal policies. It is shown that the fiscal policy stance is important for the explanation of different developments in these economies. However, fiscal policies are not the whole story, monetary policies, wage policies and open economy conditions matter as well.


THE WORK reported in this paper is a continuation of the investigations begun by Nielsen and Humphrey (1937). The material used in the study, taken from plants grown in the greenhouse, was fixed in chrom-acetic-formalin, the embedded material sectioned at 12 IL and stained with iodine-crystal-violet. The plants later were transplanted into the field where they were grown to maturity. The identifications were made with the aid of Hitchcock's (1935) "Manual of Grasses of the United States." The camera lucida drawings were made at a projected magnification of 1500X, 2100X, or 2600 X. The micro-morphological measurements reported for the nuclear diameters were made upon nuclei in metabolic condition located in the meristematic region of the root tip. Fifty measurements were used to determine the average figure given for each case discussed. These and similar data for the chromosomes are summarized in table 1. Included in this table also are the Arkansas accession numbers, the seed or clonal source, and the original collector and year of collection if known. FESTUCEAE.-Stahlin (1929) and Avdulov (1928) have reported complements of 42 and 56 chromosomes, respectively, for races of Bromus inermis Leyss. The writer has confirmed Avdulov's observations of 56 chromosomes in somatic tissue and examined material of an additional race of this series with complements of 70 chromosomes. The 56-chromosome race has thicker and shorter chromosomes and smaller nuclei than the 70-chromosome race (fig. 1, 2). Herbarium specimens prepared from the plants from which the cytological material was taken show little morphological difference other than a slight increase in size of the latter race. This is also true of other plants of these same selections now being grown in the grass nursery at this station. Bromus marginatus Nees is composed of a series of races closely paralleling that of Bromus inermis. This species has previously been reported to have races with complements of 28 by Horton and Beck (1932), of 42 by Nielsen and Humphrey (1937), and of 56 chromosomes by Avdulov (1931). To this series of races has been added an additional one with a complement of 70 (fig. 3). A comparison of the members of the complements of the 42and 70chromosome races shows that the former race has thicker chromosomes and smaller nuclei. Unfortunately, no herbarium specimens were prepared of the 42-chromosome strain previously reported so that no gross morphological comparisons can be drawn. Root tip cells of Bromus commutatus Shrad. and B. secalinus L. were characterized, respectively, by 'Received for publication April 3, 1939. Research Paper No. 646, Journal Series, University of Arkansas. complements of 56 and 14 chromosomes (fig. 4, 5). Although the diameters of the chromosomes of both species were similar, the lengths of those of the former species varied from 2.5 IL to 7.5 IL as compared with 3.5 IL to 6.0 IL for the latter. No other significant morphological differences such as constrictions and satellites were detected. Avdulov (1928) had previously reported B. secalinus to have 28 chromosomes, a complement which was subsequently verified by Stahlin (1929) and Nakajima (1931). This new number for this species thus suggests another polyploid series in members of this genus. Glyceria grandis S. Wats. was found to have 28 chromosomes (fig. 6), mostly about 0.5 Pu in diameter and from 1.5 IL to 3.5 IL in length. The individual members of the complements are irregularly rodlike to U-shaped and show no distinguishing morphological characters. The nuclei averaged 8.1 IL in diameter. Chromosome complements of 40 were observed in Eragrostis curvula (Schrad.) Nees and E. sessilispica Buckl. (fig. 7, 8). Likewise, material from Eragrostis spectabilis (Pursh) Steud., which was previously reported by Humphrey (1937) and by Nielsen and Humphrey (1937) as having 42 chromosomes, has been reexamined by the writer and found to have a complement of 40 (fig. 9), which thus places the basic number of this species in accord with those of other species of Eragrostis herein reported and with those previously reported by Avdulov (1928, 1931) and Hagerup (1932). The complements studied were made up of members characteristically about 0.3 IL in diameter which ranged from 1.0 IL to 2.2 ju in length. Their shape is generally rod-like, and they show no signs of such morphological features as constrictions. The average nuclear diameters were 7.9 IL for E. curvula, 8.0 ju for E. sessilispica, and 12.0 ju for E. spectabilis. The Festuceae just reported fall into two groups as shown by these species of Bromus, Glyceria, and Eragrostis. Bromus and Glyceria have rather long, sometimes rod-like, but more often vermiform to U-shaped chromosomes characteristically in multiples of 7; Eragrostis has short, more regularly rod-shaped or slightly curved chromosomes occurring in multiples of 10. Although these observations, and a majority of those recorded for other species of this tribe, indicate these distinct groups, there are some records that multiples of other numbers also occur in the tribe. Avdulov (1928, 1931) reported diploid numbers of 18 in Melica altissima L., M. ciliata L., M. micrantha Boiss. and Hohen., and M. nutans L. Kattermann (1930) found these numbers correct for M. altissima and M. nutans, and Hunter (1934) verified the report of 18 chromosomes in M. altissima.


In order to solve the problem that current cloud manufacturing is still lack of application mode,a five-layer architecture of cloud manufacturing(CM)system based on Agent is proposed according to the characteristics of life cycle intelligent manufacturing,required dynamic gathering,and services of different granularities in CM.Based on the service-oriented ideology,a web ontology language for services(OWL-S)of CM is proposed to realize service requirement,release,and binding,based on ontology mapping,inference engine and matching box.An expanded framework for OWL-S and semantization description for CM services is put forward,providing the theoretic foundation of match for CM services.The consult mechanism for CM services is built to realize the dynamic gathering and operation by the cooperation,competition and consult of Agents.By analyzing the activity of complex,nonlinear and obvious dynamic CM system,the paper presents the IDEF0view of CM system based on Agent and the operational mode of CM system is analyzed.


Battery-powered portable embedded systems have been widely used in many applications. These embedded systems have to concurrently perform a multitude of complex tasks under stringent time constraints. As these systems become more complex and incorporate more functionality, they became more power-hungry. Thus, reducing power consumption and extending battery lifespan while guaranteeing the timing constraints has became a critical aspect in designing such systems. This gives rise to three aspects of research: (i) Guaranteeing the execution of the hard real-time tasks by their deadlines, (ii) Determining the minimum voltage under which each task can be executed, and (iii) Techniques to take advantage of run-time variations in the execution times of tasks. In this research, we present techniques that address the above aspects in single and multi processor embedded systems. We study the performance of the proposed techniques on various benchmarks in terms of energy savings. iv To my Parents and the Real-Time Embedded Systems Research Community v ACKNOWLEDGMENTS

The teaching of the history of natural science is to inhance the hamanist,philosophical and scien-tific qualities.It includes the teaching of fundamental knowledge,scientific thinking,methodology,scientific spir-it,humanism and philosophy.In teaching,several key points should be deelt well with.


Bioavailability (BA) is defined as the rate and extent to which the active ingredient or active moiety is absorbed from a drug product and becomes available at the site of action. For drug products that are not intended to be absorbed into the bloodstream, bioavailability may be assessed by measurements intended to reflect the rate and extent to which the active ingredient or active moiety becomes available at the site of action.1 Some drugs have poor bioavailability and hence take a longer time to act. These drugs therefore do not pass the phase 1 of the clinical trials as these do not meet the necessary criteria of having the maximum bioavailability and hence show a delayed onset of action. In such cases of bioavailability issues, one of the optimal solutions can be bioenhancement of that drug with a suitable bioenhancer to augment its bioavailabilty and hence a dose reduction. There are some drugs, however, which have a moderate bioavailability but only when given in higher doses. One such drug is Secnidazole.


The attempts of six Texas cities to meet the transportation needs of handicapped citizens by making extensive use of existing community transportation providers are described. An analysis of these experiences reveals that intuitive solutions to providing cost-effective services for handicapped riders are often simplistic. In particular the analysis found that (a) contracting with an existing provider is only cost-effective if the provider is asked to perform traditional services and not innovative ones, (b) contracting with an existing provider can only generate cost savings if a city is willing to trade off direct control and supervision for lower unit costs, (c) dedicated services (vehicles and drivers) can provide a high level of service but often at high unit costs, (d) segregating riders who require minimal assistance from those who require extensive assistance can reduce costs if different providers are used for each group, and (e) every limitation on rider eligibility and contract service provision generates the need for additional administrative staff, which can significantly increase unit costs. The experiences of the six Texas cities suggest that solutions to the problem of devising transportation sevices for special groups depends on careful analysis of the capabilities of existing community providers; a firm understanding of the trade-offs between levels of service, cost, and control; and some hard decisions about what level of transportation service a community expects and to which special groups it should be delivered.

Purpose: Strictosidine-β-D-glucosidase (SGD) is considered as a key enzyme in the production of bisindole alkaloids in Catharanthus roseus. The present study illustrated the production of a short sequence of this enzyme in Escherichia coli without codon optimization. Methods: Strictosidine-β-D-glucosidase (sgd) gene short sequence (1434 bp), which lacks the conserved sequence KGFFVWS and the localization peptide sequence at the C-terminal, was amplified from cDNA of C. roseus leaves, cloned and expressed in Escherichia coli. The activity of the produced protein in cell free lysate was tested using total alkaloid extract of C. roseus leaves. Results: HPLC and LC-MS analysis of the assay mixture revealed the disappearance of the strictosidine peak. Conclusion: SGD short sequence can be produced in Escherichia coli in active form without codon optimization.


Birth defects are universal problems associated with poor management outcomes in children, especially in developing countries where its burden is enormous. Media advocacy is believed to help in reducing these poor outcomes. This study assessed the level of awareness of birth defects in women and the impact of the media in Nigeria.

This was a descriptive cross-sectional study of 778 women, conducted in the outpatient clinics of two major referral hospitals in Ibadan, Nigeria, from March to October 2019.

Of the 778 women, 768 were administered a structured questionnaire and 10 women whose children have been managed for a congenital anomaly before were interviewed using an in-depth interview guide. Of the 768 respondents, 600 (78.1%) were in the third and fourth decades of life and 577 (75.1%) women have heard about birth defects before. A total of 348 (60.3%) and 134 (23.2%) women heard about it from the hospital and mass media, respectively, with 65.0% of them believing that the media were helping in educating people about birth defects. There was a statistically significant relationship between the awareness levels and the respondents' occupation (χ2 = 28.914, P < 0.001), educational status (χ2=43.325, P < 0.001), religion (χ2 = 10.376, P = 0.016), antenatal clinic attendance (χ2 = 5.035, P = 0.025), and history of previous mid-trimester abortion (χ2 = 7.689, P = 0.006).

The level of awareness about birth defects is good but not enough; there is a need for greater media involvement in disseminating information on the occurrence of birth defects.


Uniform amorphous aluminium phosphate thin films with precisely controlled thickness and tunable composition were deposited on nitrogen-doped carbon nanotubes at 150 °C through a new atomic layer deposition approach.


Background: The safety of healthcare workers exposed to formaldehyde remains a great matter of concern for healthcare management units. This work aimed at describing the results of a combined monitoring approach (environmental and biological) to manage occupational exposure to formaldehyde in a hospital setting. Design and Methods: Environmental monitoring of working spaces and biological monitoring of urinary formaldehyde in 16 exposed healthcare workers of the Anatomic Pathology Unit of a University Hospital in Southern Italy was performed on a fouryear timescale (2016-2019). Results: Values of aero-dispersed formaldehyde identified were on average low; although workers' urinary formaldehyde levels were also minimal, the statistical analysis highlighted a slight weekly accumulation. Conclusions: Our data confirm that both environmental and biological monitoring are important to identify risk situations, in particular when values of hazardous compounds are below the accepted occupational exposure levels. Significance for public health Health workers' regular exposure to formaldehyde may be responsible for long-term health issues; unfortunately, threshold limits of this compound are not harmonized between different government agencies. The combination of environmental and biological monitoring thus becomes an invaluable tool to preserve worker's safety and effectively assess chemical risk in hospital settings.

This paper presents a combined feature extraction method to improve the performance of bag-of-features image classification. The bag-of-features approach is the most popular approach for generic object recognition and uses global statistics (histogram) of visual words. To alleviate the loss of spatial layout information, the local statistics of visual words is also used in many researches. However, it is possible to extract richer information from these global or local statistics of visual words. We apply 10 relevant operations to global/local statistics of visual words. Each operation is meaningful to describe the property of the pairwise relationship among histogram components. For example, multiplication indicates strong co-occurrence of different visual words and binarized minus operator indicates bigger/smaller relationship. Because the pairwise combination of visual words is large, we apply feature selection methods including fisher discriminant criterion and L1-SVM. Experimental results using Scene-15 dataset show that min operator achieved the best performance for global statistics, and division and binarized operators achieved better performance for local statistics.


The Chameleon scalar field model proposed by Khoury and Weltman presents an alternative mechanism for circumventing the constraints from local tests of gravity by mediating a fifth force for cosmological expansion, which could result in experimental signatures detectable through modest improvements of current laboratory set‐ups in the vicinity of oscillating matter. In this paper, the oscillation of a dielectric by a crossed EM field is investigated in light of the Chameleon model. An EM excited Chameleon field‐force equation is developed and compared to several EM experiments using the Barium Titanate based dielectric material.

Authentication among the various communicating devices within wireless sensor networks during broadcasting is most significant among the other primary security services. This authentication during broadcasting services allows multiple mobile end‐devices to transmit messages dynamically and securely for fasten consumer tracking and sustaining privacy of the data transferred in the insecure sensor network. To enhance this authentication protocol for secure end‐users message distribution, this research work has introduced a novel identity (ID) based cryptographic technique that employs ElGmal‐elliptic‐curve cryptography and digital signature without implementing bilinear paring operation to reduce huge burden of computation overhead. Additionally, to accelerate the performance of the proposed authentication protocol, the size of the signature along with the encryption key is minimized. Eventually, the authentication protocol provides comparatively less computational complexity with secure and faster key management. The performance analysis supports the aforesaid claim as well as reflects the supremacy of the proposed scheme over the handover authentication protocol and bilinear pairings based authentication schemes.

The long-lived pioneer species Pericopsis elata is one of the rare tropical timbers on the list of the Convention on International Trade of Endangered Species, supporting the need for accurate and reliable growth data. In one planted and one natural forest in the Democratic Republic of Congo, respectively four and 37 Pericopsis stem disks were collected. The tree-ring series of planted trees were used to confirm annual tree-ring formation. For the natural forest, a tree-ring chronology with 24 stem disks ranged from 1852 up to 2008. This chronology was compared with time-series of local precipitation, resulting in a significant correlation with the second half of the rainy season (September-November). This seasonal precipitation was related with sea surface temperatures of the West Indian Ocean. Higher precipitation during El Nino years corresponded with higher tree-ring indices but differences were not significant. In addition, pointer years were rare and did not have a consistent link with extreme climatic conditions. The existence of annual tree rings encourages further tree-ring analyses of P. elata and other flagship timber species in order to further document climate-growth responses and to provide the long-term framework that is needed for sustainable management planning.

Transition metal ions are biologically required yet toxic when in excess. As such, prokaryotes have developed metal homeostasis systems that allow for the acquisition of essential metal ions, the delivery of these metal ions to target proteins, and the export of metal ions from the cell. Specialized metal-binding proteins termed metallosensors bind to a cognate metal ion(s) in the cell and either transcriptionally repress the expression of importers or de-repress the expression of exporters or sequestration systems and therefore govern cellular metal homeostasis. Metallosensors must be selective and appropriately sensitive toward the binding of their cognate metals. Prokaryotic metallosensors have been identified in ten different protein structural families. Each family exploits either one general metal-binding-site region, individual members of which have evolved different coordination sites, or alternatively, employs multiple metal-binding sites to effect coordination of different metal ions. There is now broad support for the hypothesis that metal responsiveness in metallosensors is most closely linked to the coordination number and geometry adopted by cognate metal ion(s), and this is the subject of this article. Since a range of metal ions can be collectively sensed by a single repressor family, a particular protein fold cannot be specific for one particular metal ion. In fact, the converse is true: nature has used convergent evolution to evolve metal-specific sensors on a variety of structural scaffolds that exploit common principles of coordination chemistry (ligand type, coordination number, and geometry) to effect the same biological outcome.

Energy tax policy has an irreplaceable role in promoting conventional energy conservation, sustainable use and promotion of new energy sources. But China's current energy taxes still has many problems and needs an energy tax reforms. The effective implementation of the energy tax policy reform must have relevant supporting mechanisms to ensure implementation of the policy. Thus we need analyze the behavioral characteristics and trade-offs involved in policy-related aspects to achieve the establishment of appropriate safeguards.


We calculate the probability distribution of the transmission eigenvalues ${T}_{n}$ of Bogoliubov quasiparticles at the Fermi level in an ensemble of chaotic Andreev quantum dots. The four Altland-Zirnbauer symmetry classes (determined by the presence or absence of time-reversal and spin-rotation symmetries) give rise to four circular ensembles of scattering matrices. We determine $P({{T}_{n}})$ for each ensemble, characterized by two symmetry indices $\ensuremath{\beta}$ and $\ensuremath{\gamma}$. For a single $d$-fold degenerate transmission channel we thus obtain the distribution $P(g)\ensuremath{\propto}{g}^{\ensuremath{-}1+\ensuremath{\beta}/2}{(1\ensuremath{-}g)}^{\ensuremath{\gamma}/2}$ of the thermal conductance $g$ (in units of $d{\ensuremath{\pi}}^{2}{k}_{B}^{2}{T}_{0}/6h$ at low temperatures ${T}_{0}$). We show how this single-channel limit can be reached using a topological insulator or superconductor, without running into the problem of fermion doubling.


This work presents an improved control structure for side-products of a classical crude oil unit. Taking its basic principles from a Shinskey idea, it offers two original solutions by implementing a control loops dynamic decoupler and changing from PID to robust feed-forward controllers (for level control in the main column and also in sidestripers). The proposed control scheme was extensively tested by simulation, very good results being obtained by following many operating scenarios, as one can see from the selected examples in this paper. Taking this fact into account, such an improved products quality structure may be subject for an industrial implementation. Copyright @ 2006 IFAC


The growing demands for wireless communication services pose new challenges in the coming generation of cellular networks design. In Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) networks, ever-higher data rate and energy efficiency (EE) are required to meet the increasing demands in cellular traffic. High data rates can be achieved, however, it requires high level of energy consumption which needs to be controlled especially in this era of green communication trends. The energy consumption of cellular networks worldwide has become a major obstacle to the continued future development of mobile data services, considering that the number of mobile phone users worldwide has already surpassed 4 billion and as the near exponential increase of data traffic carried over mobile networks continues, mobile network operators are faced with rapidly increasing energy costs and regulatory pressures to reduce their carbon footprint to operate more "green" networks. Hence, efficient solutions are necessary to optimize EE and at the same time achieve high data rates to meet green LTE requirements. This thesis proposed an efficient algorithm, namely, the Quality of Service (QoS) and Energy Efficient Aware (QEEA). The goal of QEEA is to achieve maximum throughput and improve the EE by using low transmitted power (43 dBm) which is the lowest power setting according to the 3GPP LTE specifications. This algorithm considers the head of line (HOL) delay, achievable throughput, past average throughput and transmitted power…

Objective To examine the relationship between visit-to-visit systolic blood pressure (SBP) variability and patient-reported outcome measure of disability in multiple sclerosis (MS) patients. Design A retrospective cohort study of individuals with MS who completed a patient-determined disease steps (PDDS) scale between 2011 and 2015 at an MS specialty clinic. Participants Individuals with MS for whom both a completed PDDS scale and ≥3 SBP measures within the prior 12 months of the survey were available. Main outcome measure Participants were grouped into three classes of disability (no or mild (PDDS 0–1), moderate (2–3), severe (4–7)). SBP variability was calculated as within-subject SD using all SBP measures taken during the past 12 months. SBP variability was analysed by Tertile groups. Results Ninety-two subjects were included in this analysis. Mean PDDS score was 2.22±1.89. Compared with subjects in Tertile 1 (lowest variability), the odds of being in a higher disability group was 3.5 times higher (OR=3.48; 95% CI: 1.08 to 11.25; p=0.037) in Tertile 2 and 5.2 times higher (OR=5.19; 95% CI: 1.53 to 17.61; p=0.008) in Tertile 3 (highest variability), independent of mean SBP, age, sex, race/ethnicity, body mass index and comorbidities (p for trend=0.008). Mean PDDS scores were 1.52±1.18 in Tertile 1, 2.73±1.02 in Tertile 2 and 2.42±0.89 in Tertile 3 after adjusting for the same covariates. Conclusions Our results show a significant gradient relationship between SBP variability and MS-related disability. More research is needed to determine the underlying pathophysiological relationship between SBP variability and MS disability progression.
