This paper introduces a simple design of ultra-wideband negative index metamaterials using complementary split-ring resonator (SRR) with inductive load strip (ILS) structure. The proposed metamaterial is not only promoted to control magnetic field at low frequency but the complementary ring also controls the electric and magnetic field in the ultra-wideband. The simulation results demonstrate the negative reflection index bandwidth of 157% from the operation frequencies of 1.93 GHz to 15.91 GHz.


Clinical study designs with randomization after the initial study treatment have been used in diverse disease areas such as arrhythmia, Alzheimer's disease, schizophrenia, migraine, headache, cancer, acquired immunodeficiency syndrome, and irritable bowel syndrome. They are useful in situations where the placebo-controlled parallel group trial would be difficult to perform, such as in the investigation of long-term efficacy of a drug when long-term placebo treatment is not feasible, to address specific scientific questions, or to evaluate complex treatment schemes. Clinical studies with randomization after the initial study treatment are conducted in at least two stages. In the first stage, patients might either commence with a single treatment in an open-label fashion, or they might be randomized to several treatments, possibly including a control. A treatment-free interval might follow. Depending on the scientific question addressed by the trial, entry in the second trial stage might depend on the patient's benefit from the initial treatment. Further randomized trial stages can be added in the same fashion. The application of the approach will be discussed in detail for randomized withdrawal designs, randomized delayed start designs, and randomized retreatment designs.

Numerous branches of industry, involving the textile and clothing sector, are subjected to various negative trends of the COVID-19 pandemic period and other crises. Crisis management in a systematic manner within a company represents one of the possible replies aiming at reducing the adverse effects of these events. The analysis of companies' experiences in encountering such an unwanted event shows that good communication facilitates crisis management. The main goal of this paper is to consider the role of public relations in the crisis management. The first part of this paper considers different forms of crisis that every production company has to take into account. The middle part of the paper focuses on the crisis management process, and, also, analyzes possible communication strategies. In the final part of the paper, attention is paid to the recent experiences in terms of crisis communication management in well-known companies.


Online transactions have become increasingly crucial in worldwide social and commercial activities as the Internet has risen in popularity. The online auction has gradually developed into a major trade mode as an effective technique of online trading. This paper mainly studies the factors that influence the decision of buyers and sellers in the new online auction of the group-buying auction, reverse auction, and buy-it-now auction. It is found that psychological factors often affect consumers' entry time in online group-buying auctions, and sellers' use of static public reserve prices or secret reserve prices will lead to different results. In an online reverse auction, buyers can improve their own interests by colluding, while sellers' expectations of buyers and information processing ability have certain effects on the present and future decision-making. In an online buy-it-now auction, consumers' risk sensitivity will affect buyers' strategy, while sellers' price-setting strategy will affect their own earnings. This paper aims to comprehensively analyze and summarize the strategies of buyers and sellers in each online auction, hoping to provide useful information for participants in the online auction.


Newborn pulsars can accelerate nuclei up to 1020 eV in their magnetosphere. The accelerated particles, which follow a unique E−1 energy spectrum at injection, further propagate through the surrounding supernova ejecta, and then reach the earth. The propagation softens the spectrum and generates a series of secondary particles as cosmic rays interact with the intervening backgrounds. With the proper injection composition, extragalactic pulsars can reproduce the energy spectrum and chemical composition (Xmax and RMS-Xmax) of ultrahigh energy cosmic rays observed by the Auger Observatory. In addition, the Galactic pulsar population can contribute significantly to cosmic rays between 1016 and 1018 eV, depending on the Galactic diffusion parameters. This contribution can bridge the gap between predictions of cosmic rays produced by supernova remnants and the observed spectrum and composition just below the ankle. The pulsar sources also produce high energy neutrinos, with flux and spectrum index dependent on the source properties. By average, pulsars that contribute to detectable neutrinos have a birthrate 1 per 1200 years.


An analysis of a teaching environment with regard to interprofessional practice was done using both qualitative and quantitative methods. Medical, nursing and other health professional staff and students from two hospital units (medical and surgical) completed two surveys. The students were also interviewed. Staff differed in survey results among disciplines, with nurses and other health professionals having a more positive view of interprofessional collaboration than physicians. Student interviews supported our hypothesis that little formal or informal interprofessional education occurred during clinical rotations. Students had little understanding of the nature of collaborative behavior, and appeared to learn their discipline's attitudes and practices through tacit observation of staff behaviors. This appears to reinforce disciplinary stereotypes, and may be a significant barrier to the development of collaborative practice. These results have implications for the design of interprofessional curriculum in clinical practicums.


The aim of this research was to obtain the grafted copolymer of chitosan with acrylamide using the electron beam irradiation. Radiation dose was varied from 6 to 160 kGy. The highest yield of the product was observed at radiation dose of 12–40 kGy. Further increase in the dose caused a decrease in the product yield as well as its solubility in water. Using gel permeation chromatography, it was confirmed that unreacted chitosan remained in the product. NMR study of the water-soluble part of the product obtained under the doses of 6, 12, and 20 kGy showed that the length of the side chains of grafted acrylamide was about 2 elementary units. Investigation of chitosan solutions by means of dynamic light scattering revealed the presence of chitosan agglomerates in the solution. The possibility of obtaining dense films was demonstrated. Mechanical treatment of the copolymer in the ball mill caused an increase in the solubility of the samples obtained even at radiation doses of 80 and 160 kGy. It was determined by means of chromatographic methods that there were no products with low molecular weight in the ball-milled product, and unreacted chitosan did not undergo mechanocracking during the mechanical treatment.


Aspects of the invention provide systems and methods for using ballast sensors to detect rock fall events in a vicinity of railway tracks or similar roadways or tracks. The ballast sensors are spaced apart from the tracks. Particular embodiments permit the use of signals from the ballast sensors to discriminate rock fall events from other types of events and to detect the hypocenter of a rock fall event.


For the purpose of studying the mechanism of lowering ignition voltage in the Gao-type He-Ne laser, three kinds of laser tubes (the traditional type , the Gao-type I and Gao-type II , see Fig. 1 .) have been made and ignition voltage measurements were performed in several gases (He, Ne, He-Ne, Ar, Kr, H2 and N2). The experimental results showed that the ignition voltages for Gao-types are fairly lower than that of the traditioni one, but this effect persists only within a certain range of gas pressure. As the gas pressure inereases to a certain value P0, which depends on the gas kind, the lowering effects vanish. Figure 1 shows schematically the three kinds oflaser tubes, while Figure 2 shows the dependences ofbreakdown voltages on gas pressures. It is seen that the lowering effect tends to zero as gas pressure increases. A theoretical explanation for the experimental results is also given.


The evaluation of teaching quality is an important part of the quality management of teaching in colleges and universities. Many evaluation systems exist shortcomings, which are not suitable for the evaluation of English class. Because English subject has its own characteristics, in which the evaluation subject taken on students is more suitable than on teachers. This paper will propose a college English evaluation index system on the basis of students as the evaluation subject. Since the evaluation indicators are mainly qualitative indicators, which makes the evaluation value fuzzy, this paper proposes a new evaluation method of college English classroom teaching evaluation based on linguistic terms, triangular fuzzy numbers and preference selection index method. Finally, an algorithm case is analyzed to illustrate the effectiveness and feasibility of the proposed method.


Switzerland qualifies for European Union (EU) membership but is not a member and has rejected membership in the European Economic Area (EEA). It has developed a close, albeit unique, form of association with the EU – generally referred to as sectorial bilateralism. In this chapter I focus on the democratic implications of Switzerland's bilateral relationship with the EU, with particular emphasis on autonomy and accountability. The assessment must take proper heed of the fact that Swiss democracy is strongly shaped by classical republican ideas of popular sovereignty and that liberal or constitutional understandings of democracy have not taken hold in a similar way. In the next section I provide an overview of the Swiss model of democracy and show how this ideologically and institutionally enshrined understanding of democracy to a large extent accounts for why a majority of the Swiss people refused to exchange direct-democratic veto rights with rights to be represented in rule-shaping and -making in Brussels, because that would represent a paradigmatic shift from republicanism to liberalism. The republican tradition can explain Swiss hesitance to establish closer political ties with the EU. Nevertheless, I believe it cannot justify Switzerland's distinct association with the EU, because it draws on a very traditional understanding of republicanism, one that is not adequate anymore for understanding political autonomy in times of massive trans-boundary flows and interdependencies. A neo-republican approach, in contrast, takes these conditions better into account, reconceptualises political autonomy and introduces non-domination as a core concept. When we apply such a neo-republican understanding of political autonomy, Switzerland's bilateralism has to be evaluated much more critically, because it combines strong resistance against interference from neighbouring states and international organisations with an extreme opportunism towards the demands of multinational corporations. Such a stance undermines the capacities of larger polities like the EU to

Objectives The purpose of this study was to investigate the effectiveness of emotional regulation training group therapy, based on Dialectical Behavioral Therapy (DBT) and Cognitive Therapy, on improving emotional regulation and distress tolerance skills and relapse prevention in addicts. Method In a quasiexperimental study, 39 patients with the diagnosis of opioid dependence based on DSM-IV criteria were randomly assigned in to two experimental and one control groups. The experimental groups took 10 ninety-minute sessions of group therapy. The subjects were evaluated using the Opiate Treatment Index (OPI), General Health Questionnaire-28 (GHQ-28), and Distress Tolerance and Difficulties in Emotion Regulation Scales prior to the start of treatment, and at the sixteenth session. The control group did not take group therapy and was merely treated with naltrexone. Data were analyzed using repeated measures ANOVA and χ2 test. Results Scheffe test showed that both emotion regulation training and cognitive therapy were more effective than naltrexone increasing distress tolerance, emotion regulation enhancement, and decreasing the amount of drug abuse, health improvement, social functioning, somatic symptoms, anxiety, social dysfunction and depression enhancement (P<0.05). In addition, emotion regulation training was more effective than cognitive therapy, increasing distress tolerance and emotional regulation enhancement (p<0.05). Conclusion It seems that DBT skill training increase the effectiveness of pharmacotherapy and is more effective than cognitive therapy.


Plate subduction and collision zones are some of the most active tectonic regions on the Earth, which control the mass and energy exchange between the Earth's surface and interior, produce volcanism and the majority of great earthquakes, and are strongly correlated with the generation of mineral resources. The subducting oceanic slab penetrates through the mantle, interacts with multiple phase transition layers and results in variable slab morphologies and complex mantle flow. On the other hand, the continental plate subduction and collision generally follow the closure of oceanic subduction and lead to formation of great mountain belts on the Earth. The subduction/ collision zone is a key element of plate tectonics and geodynamics, involving multiple processes and multi-scale mechanisms; however, many problems in this research field remain unclear and widely debated. The set of 14 studies in this special Research Topic aimed to bring together multi-scale geodynamic modeling studies, with the general goal of understanding the processes, dynamics, and effects of plate subduction and collision, as well as providing a general framework for future research efforts.


Looking back at his tenure as resident dramaturg of Dancemakers in Toronto, Jacob Zimmer argues that dramaturgy is a friendship: a sensibility and a way of looking and moving towards meaning with artists and audiences, not a job description.

This paper describes the cycle time reduction approach of injection moulding machine for DVD manufacturing. Optimizing the parameters of the injection moulding machine is critical to improve manufacturing processes. This research focuses on the optimization of injection moulding machine parameters. Suggestions for process improvements are made based on the results of a designed experiment. The objective of this experiment is to provide statistical evidence for optimizing parameters of an injection moulding machine. The machine parameters to be investigated include cooling time, holding time, and robot take out time limit. These parameters are evaluated against the problem of decreasing the cycle time for each part. Experimental data were collected following the designed experiment procedures, and a statistical analysis was performed to give a basis for process improvement recommendations. The results of the experiment showed a way to achieve the goal of optimizing the injection moulding machine in a sensible and cost efficient way.


RFID-enabled business models are proposed in this chapter to innovate supply chain management. The models demonstrated benefits from automatically captured real-time information in supply chain operations. The resulting visibility creates chances to operate businesses in more responsive, dynamic, and efficient scenarios. The actual initiative of such novel RFID enabled applications is therefore to encourage intelligent supply chain management to dynamically respond changes and events in real-time. As the RFID implementation costs are continuously decreasing, it is expected that more novel business models would be inspired by the technological advancement to foster more intelligent supply chains in the near future.

Point cloud semantic segmentation is widely used in scene analysis. We propose a point cloud semantic segmentation network based on adaptive random sampling and self-attention. The network extracts local centroids using random sampling, enriches feature information of the centroids using the proposed adaptive optimization module, and then learns correlations and differences between feature vectors using a feature aggregation module based on the self-attentiveness mechanism to make feature cross-fertilization more adequate, which effectively improves the performance of semantic segmentation. Experimental results on S3DIS show that the network consumes less computing time, but improves the Mean Intersection over Union (mIou) by 14.4% and overall accuracy (oAcc) by 6.4% over the baseline network PointNet++.


Haemoglobin is present in the nitrogen-fixing root nodules of both legumes and the non-legume Parasponia, where it facilitates the diffusion of oxygen to the respiring bacteria at a free oxygen concentration too low to inhibit the oxygen sensitive nitrogenase complex (reviewed by Appleby, 1984; Appleby et al, 1988). A closely related non-nodulating relative of Parasponia, Trema tomentosa, has a haemoglobin gene that is expressed in roots (Bogusz et al, 1988). Both the Parasponia and Trema haemoglobin promoters direct expression of a reporter gene in the nodules of a transgenic legume (Bogusz et al, 1988). However, this thesis demonstrates that, unlike expression of the leghaemoglobins and endogenous Parasponia haemoglobin, these promoters confer high expression in uninfected tissues of Lotus nodules, and low expression in the bacteroid containing cells. This nodule expression pattern is similar to that of a nonsymbiotic haemoglobin gene from Casuarina, analysed concurrently with this study (Jacobsen-Lyon et al, in preparation), which is expressed in parenchyma of both roots and nodules. Thus, regulation of the Parasponia and Trema haemoglobin genes in a transgenic legume reflects aspects of both symbiotic and nonsymbiotic expression and suggests distinct signals control organ versus cell specificity. The discovery of haemoglobin and haemoglobin genes in phylogenetically diverse non-legume genera, including Parasponia, Trema, Casuarina and Hordeum (barley) (Appleby et al, 1983; Bogusz et al, 1988; Fleming et al, 1987; Christensen et al, 1991; Taylor et al, 1993) led to the proposal that haemoglobin may have a fundamental, but as yet unknown, function in all plants independent of its role in symbiotic nodules (Appleby et al, 1988; 1990). This thesis explores the suggestion that legumes must have a haemoglobin gene expressed in nonsymbiotic tissue in addition to the nodule specific leghaemoglobin genes (Appleby et al, 1988; 1990). The apparent pseudogene /bps 1 has been suggested as the soybean nonsymbiotic haemoglobin gene (Nap and Bisseling, 1990b,c). However, no evidence of expression of lbps1, either in soybean or transgenic Lotus, was found in this study and it is likely that lbps1 is a true pseudogene.


Objectlve To investigate the expressions of Fas,FasL and P53 in breast cancer and paracancerous tissues of human to explore the relationship of tumor gene and apoptosis regulating protein with developing of breastcancer.Methods The human breast cancer tissues and relative normal breast tissues were collected from the samples of 21 patients with breast cancer and analyzed by immunocytochemistry.Results The positive rate of Fas expression in breast cancer was significantly lower than that in relative normal breast tissues(P0.01)with much lower in lymphatic metastasis than in nonmetastasis.The positive rates of FasL and P53 expressions in breast cancer were significantly higher than those in relative normal breast tissues(P0.01)with much lower in lymphatic metastasis than in nonmetastasis.Conclusion The abnormal expressions of Fas/FasL in breast cancer suggest that they are valuable in predicting the clinical prognosis of breast cancer,and the overexpression of P53 gene in breast cancer was closely associated with the tumor development.


To the Editor: —There was a rather important clerical error in the typewritten manuscript furnished you for President Taft's speech before the Medical Club of Philadelphia. [The Journal, May 13, 1911, page 1400, middle of first column.] He said, "I need not go further than to say that twenty-four per cent, of the sick of the Japanese army were afflicted with beriberi during the Russo-Japanese War." The words "sick of the" were omitted in this sentence, just before the word "Japanese." It seems to me the error is so obvious that it will not make any great difference, except to certain literal souls who will perhaps write to inquire about it. I am asked to write you in the name of the White House to make the correction, with the statement that it was a clerical error.

Summary The storage of electric peak energy by means of hydrogen has been investigated for a stationary hydride storage 3 system with a capacity of 100 - 1 000 MWh (32 000 - 320 000 m of H ) under technical and economic aspects. Ti,Cr,Mn-based low t~mperature hydrides developed at Daimler-Benz which store 2 % of hydrogen were chosen for the construction of the sta tionary hydrogen storage and their thermodynamic and kinetic properties as well as their thermal conductivity as a basic factor for the technological computation were examined. The low thermal conductivity of the material is considerably im proved by the admixture of metal powder - a method developed by Daimler-Benz. An operation cycle comprising 8 hours each of absorption, storage and desorption was assumed. In this case heat flow is the rate limiting factor. The H 2 -storage pressure is 10 or 55 bars. Two variants (steel or concrete outer jacket) are designed and described. Depending on its size the hydride storage system cons~sts of 2 or 20 storage units with a H -capacity of 16 000 m each. Several alter natives for th~ selection of a suitable location for the hydride storage system are mentioned and discussed and the investment and operating costs for 4 hydride storage systems are quoted. A comparison with the costs of other forms of hydrogen storage show that the hydrogen storage with hydrides is more economical than the storage of liquid hydrogen and pressurized gas.


Activity levels of the enzymes involved in ketone utilization were compared in heart, fast-twitch red, slow-twitch red, and fast-twitch white types of muscles in rats. 3-Hydroxybutyrate dehydrogenase, 3-ketoacid CoA-transferase, and acetoacetyl-CoA thiolase activities were lowest in white muscle, higher in slow red than in fast red muscle, and highest in the heart. The large differences between the four muscle types in the levels of these enzymes reflects differences in both mitochondrial content and composition. Differences in composition were evidenced by large dissimilarities between the different muscle types in the ratios of the activities of the enzymes of ketone oxidation to each other and to citrate synthase and cytochrome c. Of particular interest is the finding that, despite the fact that in the rat slow red muscle has a lower content of mitochondria than fast red muscle, 3-hydroxybutyrate dehydrogenase activity is 140% higher and 3-ketoacid CoA-transferase is 70% higher in slow red than in fast red muscle.

A 14-week-long program of treadmill running induced increases in the levels of ketone utilization enzymes in all three types of skeletal muscle but not in heart; 3-hydroxybutyrate dehydrogenase became measurable, though at very low levels, in white muscle; increased 2.6-fold in slow red muscle, and 6-fold in fast red muscle. 3-Ketoacid CoA-transferase increased 2-fold in both fast red and white types of muscle, but only 26% in slow red muscle. Acetoacetyl-CoA thiolase activity increased 40–45% in all three types of skeletal muscle. In contrast, citrate synthase and cytochrome c increased approximately 2-fold in all three types of skeletal muscle. These adaptive changes tend to make skeletal muscles more like heart muscle in their enzyme patterns and may help to explain why physically trained, as compared to untrained, individuals do not develop post-exercise ketosis.


DVB-S is a functioning system to transmit digital broadcasts from satellite and received by a device named digital satellite receiver. Along with the increasing development of technology, the system with the DVB-S broadcasting is becoming obsolete and change over using the standard DVB-S systems called DVB-S2. With the latest technology, the DVB-S2 receiver is capable to display broadcast with MPEG-4 format and capture more broadcast than the predecessor system. Since using satellite as a repeater, the transmiter and receiver use a parabolic antenna types. The basic material used in a dish are made from zinc drums or commonly called as wajan bolic. In its design, using a wok with a diameter of ± 120 cm and depth of 17 cm. In simple flow, signal reception in wajan bolic antenna that are sent through the satellite signal received by antenna, then reflected by the reflector towards LNB to be transmitted on receiver device. The larger reflector used, the greater coverage antenna get broadcast from a satellite, it is caused by reflected signals that lead to the antenna reflected with maximum towards LNB used. Based on the experiments conducted, antenna wajan bolic successfully used to support DVB-S2 system applications to capture signals from satellites and display it in digital broadcasting form. In practice, the value of C/N is taken as a reference for broadcast quality shown. The highest value of C/N generated by MORE 1 and BERITA SATU channel, with each value of C/N equal to 7 dB. Accordingly it can be stated that the greater value of C/N, the better quality of broadcasts produced.

Augustine Volcano, situated between the Cook and Katmai segments of the Eastern Aleutian Volcanic Arc, has erupted 5 times since its discovery in 1778. Eruptions are characterized by early vent-clearing eruptions with accompanying pyroclastic flows followed by dome-building and more pyroclastic flows. Bulk rock chemistry of historic and prehistoric lavas shows little variability. The lavas are calc-alkaline, low to medium K, porphyritic acid andesites, rare basalt, and minor dacite pumice. FeO*/MgO averages 1.6 over this silica range. Plagioclase phenocrysts show complicated zoning patterns, but olivine, orthopyroxene, and clinopyroxene phenocrysts show little compositional variation. Hornblende, where present, is ubiquitously oxidized and was clearly out of equilibrium during the last stages of fractionation. Evolved liquid compositions of vitriophyric domes are rhyolitic, and of pumices are slightly less evolved suggesting that individual eruptions become more fractionated with time. Comparison of glass compositions with experimental results is consistent with low pressure fractionation of a relatively dry silicate melt. Disequilibrium of amphiboles and the evolved nature of glasses indicate that shallow level fractionation plays a significant role in the evolution of Augustine magmas. This model is consistent with a shallow magma chamber inferred from geophysical models of the Augustine system and also with its simple,more » predictable eruption pattern.« less


Multiplexing the signal readout from the organic photodetector matrix is essential for high‐resolution and large‐area imaging applications. This endeavor can be realized by pixels containing photodiodes and switching elements, such as transistors or blocking diodes. The use of blocking diodes is beneficial for simpler fabrication and fewer wires than transistors. However, imagers with blocking diodes can always require additional voltage to turn off the unselected lines, which causes high standby power and increased complexity of the readout circuit. In this study, low standby power organic imagers are realized that are suitable for wearable optical imaging applications in which resources for power and readout circuits are limited. Pixels with a vertical stack of organic photodiodes and blocking diode layers are investigated. By increasing the built‐in potential of blocking diodes, the turn‐on voltage of the monolithically stacked photodiode‐blocking diode device can be adjusted to enable its turn‐off at 0 V. This leads to a three‐orders‐of‐magnitude reduction of the current of pixels at 0 V. With these pixels, imagers based on organic photodiode‐blocking diode stack devices are demonstrated with improved image quality and substantially reduced crosstalk current, while operating at zero standby power.

Summary By making use of DIC video microscopy to monitor microtubule motility we have studied the effect of several MAPs (MAPP, MAP2c, tau) on microtubule–kinesin interactions and microtubule gliding. Of the three MAPs tested, MAP2 interferes most strongly with kinesin-dependent microtubule motility.


The theory of the electron density of states due to an interstitial impurity in a transition metal developed previously (see ibid., vol.7, p.799 (1977)) is used to determine the energy of the impurity at tetrahedral and octahedral sites in FCC transition metals. The contributions to the energy are a bandstructure term due to the perturbed density of electron states, an electrostatic term to include the additional electrostatic interactions and a term arising from electron exchange and correlation. Detailed calculations are performed for the case of hydrogen in palladium and it is found that the octahedral site has lower energy than the tetrahedral site in agreement with experiment. The calculated values of the energy and heat of formation are also found to be in reasonable agreement with experiment. The accuracy of the host metal bandstructure calculation is shown to be significant. It is concluded that the theory should be sufficiently accurate to determine interstitial site energies for other transition metals.


The climate modeling, which has adequate spatial and temporal resolution, shows that the future climate of the Carpathian Basin will be much more arid and hot than nowadays. The currently used and taught assortment of the ligneous ornamental plants should be urgently revised. It is aimed in my research to collect the species which will probably be introduced in the future. They can be gathered from the Hungarian botanical gardens and research centers and from the spatially analogous territories. The collected taxa should be examined with GIS software if they will really suffer our future climate.

We conducted a survey of 83 colleges of pharmacy in the United States, Puerto Rico and Canada to determine the status of didactic and experiential paediatric pharmacotherapy teaching in entry‐level programmes. Sixty‐five completed surveys (54 from BS programmes and 11 from entry‐level PharmD programmes) were received and analysed. Forty‐four (815%) BS programmes and 11 (100%) of the entry‐level PharmD programmes provide an average of 5.1 and 9.2 h of didactic paediatric teaching, respectively. While all of the entry‐level PharmD programmes offered experiential rotations in paediatrics, only 38 (70%) provided BS students with an opportunity to receive paediatric experiential training. Colleges of pharmacy should re‐evaluate their curricula to ensure sufficient preparation of graduates in paediatric pharmacotherapy for entry‐level positions.


Textile sector is the mainstay of Pakistan's economy. Its contribution towards GDP, exports and Manufactured Value Added (MVA) is highest. It is the biggest employer of manufacturing labor force in Pakistan at 39%. More than 60% of all exports from Pakistan come from textile related products and its contribution towards GDP is 9.5%. However Pakistan Textile Industry is not providing the returns at par with its potential. Main contributing reasons for this below par performance are usually contributed to external to industry factors i.e. law and order situation, energy crisis, lack of foreign direct investment, unfavorable policies and taxations, power tariff, elimination of quotas etc. Impact of these has remained very significant. However their also are internal issues which were in the control of the industry and almost equally have contributed towards this poor performance. This paper looks into these issues and studies their impact on returns through growth and profitability. Qualitative and Quantitative Study was conducted in 30 textile firms of varying size and capacity. Internal, external and mutual i.e. supply chain issues were studied and salient are being reported. Findings about significant factors are shared with a suggested optimal course of action.


### Key points

While most anaesthetists use airway devices on a daily basis without apparent complication, they should always be aware of the possibility of injury. Knowledge of these injuries aids prevention and allows timely diagnosis and correct treatment. In this article, we summarize injuries reported from common airway interventions with particular focus on post-intubation tracheal stenosis (PITS).

Allergic and irritant type reactions are much less common with single-use face masks than with reusable masks, especially where chemical disinfectants are used in the cleaning process. Soft tissue injuries such as abrasions and ulcers are possible in anaesthetic practice. However, now that prolonged face mask anaesthesia is uncommon, they are more likely to be observed in patients receiving non-invasive ventilation or continuous positive airway pressure. The eye is particularly vulnerable to contact with a face mask and corneal abrasions are possible unless a correctly sized mask is used and continued care is taken. Serious harm from the use of face masks is uncommon and appears to be caused mainly by excessive pressure. This can result either from the face mask itself or from the anaesthetist's hands when performing a jaw thrust manoeuvre and can result in sensory change to the face from pressure to the mental nerve. Likewise pressure to the mandibular branch of the facial nerve can result in paralysis of the muscles of the lower lip and chin. These examples of neuropraxia are rare, occurring only in …


ABSTRACT Hundred and forty-five novel molecules of Wittig-based Schiff-base (WSB), including copper(II) complex and precursors, were computationally screened for nonlinear optical (NLO) properties. WSB ligands were derived from various categories of amines and aldehydes. Wittig-based precursor aldehydes, (E)-2-hydroxy-5-(4-nitrostyryl)benzaldehyde (f) and 2-hydroxy-5-((1Z,3E)-4-phenylbuta-1,3-dien-1-yl) benzaldehyde (g) were synthesised and spectroscopically confirmed. Schiff-base ligands and copper(II) complex were designed, optimised and their NLO property was studied using GAUSSIAN09 computer program. For both optimisation and hyperpolarisability (finite-field approach) calculations, Density Functional Theory (DFT)-based B3LYP method was applied with LANL2DZ basis set for metal ion and 6-31G* basis set for C, H, N, O and Cl atoms. This is the first report to present the structure–activity relationship between hyperpolarisability (β) and WSB ligands containing mono imine group. The study reveals that Schiff-base ligands of the category N-2, which are the ones derived from the precursor aldehyde, 2-hydroxy-5-(4nitro-styryl)benzaldehyde and pre-polarised WSB coordinated with Cu(II), encoded as Complex-1 (β = 14.671 × 10−30 e.s.u) showed higher β values over other categories, N-1 and N-3, i.e. WSB derived from precursor aldehydes, 2-hydroxy-5-styrylbenzaldehyde and 2-hydroxy-5-((1Z,3E)-4-phenylbuta-1,3-dien-1-yl)benzaldehyde, respectively. For the first time here we report the geometrical isomeric effect on β value.


In this article, a voltage coupling enhancement (VCE) technique is developed to suppress the transient gate overvoltage of an insulated gate trigger thyristor (IGTT) in ultrahigh <italic>di/dt</italic> pulse applications. It is found that, due to the gate–cathode voltage (<italic>VG</italic>–<italic>VC</italic>) coupling associated with the intrinsic gate–cathode capacitor (<italic>Cgc</italic>) and inevitable common source inductance (<italic>LC</italic>) of IGTT, the gate voltage (<italic>VG</italic>) would oscillate with the cathode voltage <italic>VC</italic> (= <italic>LC</italic> × <italic>di/dt</italic>), which produces high gate–cathode voltage (<italic>VGC</italic>) oscillation. This easily leads to device failure especially at high <italic>di/dt</italic> pulse condition. Enhanced <italic>VG</italic> − <italic>VC</italic> coupling by increasing intrinsic <italic>Cgc</italic> can contribute to the close following of <italic>VG</italic> against <italic>VC</italic>, suppressing the transient gate overvoltage. Thus, a modified dummy gate IGTT (DG-IGTT) structure with increased <italic>Cgc</italic> is specially designed as a practical implementation of the VCE technique. Experimental results show that the DG-IGTT has a low gate overvoltage (<italic>VGC-</italic>max) of 31.2 V, whereas the <italic>VGC-</italic>max of conventional IGTT is over 136.7 V. In addition, the DG-IGTT in Kelvin source package can further achieve a much lower <italic>VGC-</italic>max of 18.5 V at ultrahigh <italic>di/dt</italic> of 32.4 kA/<italic>μ</italic>s. The DG-IGTT successfully works at the repetition rate of 200 Hz, indicating the proposed VCE technique is promising for improving device robustness in ultrahigh <italic>di/dt</italic> and repetitive pulse applications.


A 1995 study of Harare's urban population revealed that some 110,000 people (10 per cent of the city's total) were living in informal settlements (Auret, 1995). Increasing rural poverty, overcrowded communal farming areas and high youth unemployment continue to fuel a major exodus from country to city. Combined with Harare's natural population increase, it is now estimated that the capital of Zimbabwe is experiencing a growth rate of some 12 per cent per year.

Objective To study the relationship between body fat composition and insulin resistance in obese middle school students,and to provide evidence for middle school students' obesity prevention. Methods Height,body weight were examined in 940 students aged 13-14 year. Forty-seven students were selected as the obese group,whose BMI were≥95th percentile for age-and sex,and 50 health ones were taken as control group,whose BMI were 25th to 75th percentile for age-and sex. Blood pressure,fasting blood glucose and insulin,serum lipid were determined,and HOMA-IR was calculated. Assessment of body composition was measured by dual energy X-ray absorption(DEXA). Results In obese children,the levels of blood pressure,BMI,triglyceride,fasting insulin,HOMA-IR,total fat and trunk fat were all higher than the control. Multivariate regression analysis indicated that trunk fat was an independent determinant for HOMA-IR. Conclusion Trunk fat is a useful index for determination of obese students in middle schools and positively correlated to insulin resistance.


Abstract Background Appropriate recipient vessel selection is a crucial aspect of microsurgical reconstruction. The chest wall presents several options for microvascular anastomosis, the most popular being the internal mammary and thoracodorsal vessels, although they may not always be available or suitable for breast reconstruction. We propose that the lateral thoracic vessels are a useful alternative, given their central position and intraoperative exposure in a skin-sparing mastectomy. Methods and Results We have performed four abdominal flaps based on the deep inferior epigastric artery and lateral thoracic vessels as the recipient vessels. The average diameter of the lateral thoracic artery was 2 mm and the vein was 2.75 mm. There were no vessel conversions, flap failures, or complications. Excellent aesthetic results were achieved. The anatomy of the lateral thoracic artery is described. Conclusion The lateral thoracic vessels are advantageous and safe recipient vessels. Their consistent anatomy, central location, and intraoperative exposure make them useful recipient vessels in breast reconstruction.


Black non-Standard English is different in grammar (syntax) from Standard English. The advent of the 60's produced authors who explored the full possibilities of language to deal with their themes. The increased use of dialect by black authors, particularly children's authors, was a sign that the nature of the black experience as they wanted to convey it did not have to rely on traditional forms, and literary devices; that they could treat familiar, realistic ideas and situations using a familiar dialect and relate that idea more effectively.


Building on the holistic approach promoted by the Matrix, this paper examines the importance of Directions in a changing world. The Matrix is the conceptual framework which integrates the four elements feel/think/act/time into a single holistic landscape of values and entities. Recognizing the role of memory in the thinking process, three integrating relationships provide a helpful starting mnemonic underpin to the issues under consideration, viz: the interactive cycle, the proactive sequence and a tensorial postulate linking quality, entity and quantity. The faceted format for articulating multivariable problems is shown as presenting a valuable series/parallel continuum which facilitates comprehension, interaction and processing towards useful outcomes and directions. The value of key words is emphasized and special attention is given to word grouping. These groupings when displayed on the Matrix provide visual patterns which facilitate the grasping of relationships. The question of the acceptance or rejection of linkages can hence be resolved simply and effectively at both the personal and collective levels. The four paradigms forming the title of this paper, Values (89.58), Wisdom (58.89), Beliefs (49.0), and Directions (59.86) are one such grouping and their display pattern is quite striking by the strong visual delineations of vertical energy and horizontal quality. The concept of positive or negative polarity which comes from perception is a vital ingredient and none of the four words would be meaningful or reliable in isolation; yet as a foursome they can be seen to converge, with Wisdom providing the sensitive determinant and Directions providing the critical outcome. Polarity and duality exert their share of influence on beliefs and behaviour. Quality and quantity, usually depicted as pulling in opposition, do in fact interweave in partnerships which through wise choices can lead to sound directions and positive evolution.


Spectrographic techniques have been used to determine electron temperatures and densities in the interelectrode plasma of a close‐spaced high‐current cesium plasma diode. These results were obtained from the relative intensity of the radiative recombination continuum and measured line‐widths, respectively, of cesium. The diode was operated at two short‐circuit current conditions (∼15 and 18 A/cm2) with an interelectrode spacing of 0.25 mm. Contrary to some theories, these results indicate that steep temperature gradients do exist in the plasma and that maximum electron temperatures are 2800°K.


Catalogue essay in The Quay Brothers' Universum,published concurrently with the eponymous exhibition at the EYE Filmmuseum Amsterdam, 15 Dec 2013-9 March 2014.

Abstract: The Quay Brothers have created one of the most compelling bodies of work in cinema. Watching any of their films means entering a complicity of furtive glances, choreographed shadows and a melange of aural and visual motifs and tropes. Their films and non-cinematic collaborative moving image works for performances are reaching wider audiences, and there is a growing interest in art world contexts in them as artists working across creative disciplines. Museum and gallery exhibitions give audiences the opportunity to see and understand how the Quay Brothers weave a fascinating tapestry of inspirational sources into their films. Its warp – the unvarying underlying structure throughout the fabric of their work – is the puppet animation technique. The multicoloured weft threads that determine the patterns and distinctness of each of their films are drawn from the written (and unwritten) histories of art, music, architecture, cinema, performance and literature, leading us into a labyrinth of artists, authors and thinkers. Some of these are well-documented influences on the Quay Brothers, and in this essay, I will focus also on lesser-known elements in the exhibition to explore some leitmotifs, tropes and themes that are found in their films.


In order to achieve accurate and fast recognition of traffic signals, this paper compared and evaluated the detection performance of four YOLOv5 models from the detection speed and detection accuracy, and analyzed the influence of the depth and width of different network structures on the detection performance of traffic signals. Firstly, this paper introduces the basic principle of YOLOv5 algorithm and analyzes the structure characteristics of YOLOv5s, YOLOv5m, YOLOv5l and YOLOv5x network models. Secondly, the source of the dataset, the construction method and the target category contained in the image are described briefly. After the algorithm training and testing, the corresponding detection model is obtained. Finally, the recognition speed, confusion matrix, recall rate, accuracy rate and other evaluation indexes are compared and analyzed. Experimental results show that the recognition performance of YOLOv5m model is better than the other three models when considering the detection speed and detection accuracy.

An approximation method of false alarm probability and detection probability is presented using cepstrum moments. A new CFAR processor, OSEXCA-CFAR (order statistics excision cell averaged-constant false alarm rate), is proposed and its performance is discussed by computer simulation and cepstrum moments.


A 10bit 40MS/s asynchronous timing logic successive approximation analog-to-digital converter (SAR ADC) is presented, including a bootstrapped switch, a charge redistribution digital-to-analog converter(DAC) and a dynamic comparator. A redundancy compensation and a mismatch calibration are introduced to achieve conversion accuracy improvement. A monotonic capacitor switching technique is adopted to reduce the power consumption during conversion. The design of ADC was based on SMIC 0.18μm CMOS process and consumes 5.4mA at 1.8 V power supply. The SAR ADC exhibits an SNR and SFDR of 60.27dB and 65.58dB, respectively.


Tracks of motile sperm were analysed in men infected by Ureaplasma Urealyticum in semen and men non-infected. The results showed that velocity of motile sperm of positive group infected by Ureaplasma Urealyticum was significantly lower than that of negative group (P0. 01),their motile patterns were mainly turning circle and zigzag; turning circle pattern was 82. 8% (24/29) in 29 infertile men infected by Ueaplasma Urealyticum, whose wives had spontaneous abortion. These results suggested that analysis of tracks of motile sperm might be regarded as the parameter index for infection of Ureaplasma Urealyticum.


This paper focuses on the process of region formation and its interrelation with agency and regional identity. The region formation processes of two regions in Flanders (Belgium) were analysed, using a framework assessing the institutionalisation of regions. Based on semi-structured interviews and policy documents, the analysis confirmed the usefulness of the concept of institutionalisation to understand and visualise the evolution and ongoing dynamics of region formation processes. The analysis reveals the importance of the dynamic and interactive character of the different aspects of the framework of institutionalisation. The region formation processes in the two regions also indicate the importance of individual catalysts, people who stimulate synergies between the different aspects of the process, resulting in the (re)production of the region and its identity. Regional attachment or 'regional identity' was indispensable in the actions of these catalysts and the region formation processes.


The guarantee of reliable IT operation services in producing relevant, punctual, and accurate information relies on IT maturity levels. It is noted that smoothness and appropriateness of IT operation services influence rework of dissemination of information. This research included 65 online stores in West Kalimantan as the sample. Questionnaires with groups of domains of IT processes and Likert scales were used to collect the data. Managers marketing the products through online stores became the respondents. The research aimed to cognize impacts of maturity levels of IT governance on needs of IT operation services. Results indicate that values of maturity levels that are less than 2.51 are dominated by PO Domain (PO1, PO2, PO3, PO4, PO8, and PO9), AI Domain (AI4 and AI5), DS Domain (DS4 and DS5), and ME Domain (ME4). The lowest value (2.421) is at PO3 (determining IT directions). Meanwhile, the highest one (2.975) is at DS6 (identifying and allocating costs). These values of maturity levels become important indicators of perspectives on IT operation services to map structures, processes, and relationships. Management of IT resources through interrelationships of applications, information, infrastructure, and human resources is inevitably necessary.


The Discrete Memory Machine (DMM) and the Unified Memory Machine (UMM) are theoretical parallel computing models that capture the essence of the shared memory access and the global memory access of GPUs. The approximate string matching for two strings X and Y is a task to find a sub string of Y most similar to X. The main contribution of this paper is to show efficient implementations of approximate string matching on the memory machine models. Our best implementation for strings X and Y with length m and n (m≤n), respectively, runs in O(mn/w + ml) time units using n threads both on the DMM on the UMM with width w and latency l.

A description is given of a method of increasing the amount of stem cells and progenitor cells in circulation in the peripheral blood of a mammal; the method is characterised by the administration of defibrotide in combination or in temporal proximity with at least one haematopoietic factor having the capacity to mobilise haematopoietic progenitors, preferably G-CSF.


The aim of this experiment was to investigate differences in spacing behaviour, measured by the individual distance when resting and feeding, between two breeds of sheep with a different selection history. Eight groups of four pregnant ewes from the Nor-X breed (a heavy, composite breed mainly selected for growth and meat quality) and eight groups of four pregnant ewes of coloured Spæl sheep (a light breed, mainly selected for wool quality) were placed in oblong experimental pens (12 x 2 m) for 7 days. Pens had a solid resting area of wood (12 x 0.6 m) and an open horizontal feed barrier running along the 12 m long side opposite to the resting area. Black stripes for every 0.5 m were painted on the resting area and on top of the feed barrier in order to measure distance between pairs (6 possible pairs per group) from instantaneous sampling pictures drawn from digital video recordings. The heavy Nor-X ewes kept a significant larger individual distance to their pen mates both during resting and feeding compared to the lighter Spæl ewes. Spæl ewes also kept a significant smaller individual distance during resting than during feeding, but this difference according to activity was not found in Nor-X ewes. Looking at the selection history of these two breeds we discovered differences in how long these breeds had coexisted with large carnivores. Our


Characterizing the streaming potential and electroosmosis properties of porous media is essential in applying seismoelectric and electroseismic phenomena for oil exploration. Some parameters such as porosity, permeability, formation factor, pore size, the number of pores, and the zeta potential of the samples can be obtained from elementary measurements. We performed streaming potential and electro-osmosis measurements for 6 unconsolidated samples made of spherical polymer particles. To check the validity of the measurements, we also used alternative analysis to determine the average pore size of the samples and, moreover, used a sample made of sand particles to determine the zeta potential.


The invention discloses a cefaclor sustained-release tablet and a preparation method thereof. The cefaclor sustained-release tablet comprises cefaclor, a sustained-release substrate and auxiliary materials, wherein the sustained-release substrate is one or a combination of two or more of chitosan, carbomer, xanthan gum, hydroxypropyl methylcellulose and sodium alginate. Compared with an artificial synthesis material, the cefaclor sustained-release tablet has the advantages that: certain natural high polymers such as chitosan, carbomer, xanthan gum, hydroxypropyl methylcellulose, sodium alginate and the like are taken as sustained-release carrier substrates, so that stable blood concentration can be adjusted and controlled, the administration times are reduced, and intensive stimulation on a gastrointestinal tract is reduced; and the cefaclor sustained-release tablet can participate in natural metabolism of a human body, and is not accumulated in vivo. Due to the addition of these sustained-release substrates, release of the medicament is more stable, and the medicament releasing amount is basically consistent at each time interval.


Educating healthcare professionals about the social determinants of health is important in improving health outcomes of marginalized patients. Residents' experience of learning about the social determinants of health and a clinical assessment tool remains unclear.


Various observational and modeling studies have shown that the Hadley cell (HC) has widened during the past few decades. Here we present further observational evidence of the widening of the HC in the Southern Hemisphere by tracking the location of the subtropical ridge. A robust and significant poleward shift of the southern edge of the HC has been observed during the austral summer over the past three decades with a shift of 0.22° per decade between 1980 and 2012, primarily from the South Atlantic Ocean eastward to Australia. In other seasons, significant changes in the southern edge of the HC have not been observed, with a discernable regional trend having only occurred in limited regions. The comparison of these results with those derived from reanalysis data and possible causes for the summer HC expansion in the Southern Hemisphere are briefly discussed.


The ATC system must ensure the safe and expeditious movement of traffic through the TMA and down to and along the surface of the airport. There must be a plan which defines the path to be followed by each aircraft, taking account of all other proposed movements. There must also be a means of implementing this plan with adequate accuracy, or for revising it should later events make this necessary. The plan must take account of the finite accuracy with which an aircraft can navigate (using "navigation" in the broad sense of "the progress of the craft about its ways in space and time"). We will therefore discuss first the tools required for implementing any chosen plan, before discussing the planning function itself.


Diplopia is an uncommon but distressing result of orbital changes in Graves' disease. Significant extraocular muscle disorders occur usually when there is severe orbital involvement, as described under such terms as exophthalmic ophthalmoplegia (Brain and Turnbull1), thyrotropic exophthalmos (Mulvaney2), and infiltrative ophthalmopathy (Day3). Less frequently, muscle dysfunction is found with only minimal orbital swelling. Limitation of ocular movement generally develops after appearance of other signs of orbital congestion—conjunctival hyperemia and edema, lid edema, exophthalmos, and increase in intraorbital pressure with resistance to palpation. Usually there is an initial limitation of upward gaze; if the restricted movement is greater in one eye, diplopia occurs. Later there may be limitation of lateral motion. In extreme cases, the eyes may become more or less fixed in a position of depression. The degree of extraocular muscle involvement is exceedingly variable. In mild forms of orbital disease, myopathy is minimal and often

This paper considers a multiperiod inventory model in which a supplier provides alternative lead-time choices to customers: a short or a long lead time. The supplier operates in a batch-production mode. Orders from slow customers can be taken by the supplier and included in the next production cycle, while orders from fast customers have to be satisfied from the onhand inventory. We denote the action of providing a short lead-time product to a long lead-time customer as the inventory-commitment decision, and we also denote the initial inventory stocking as the inventory-replenishment decision. We first characterize the optimal inventory-commitment policy. We then prove that the optimal inventory-replenishment policy is a base-stock type. We extend our analysis to models to consider a multicycle setting, a case of a supply capacity constraint, and a case in which the inventory holding cost is charged in real time. We also compare the performances of the optimal inventory-commitment policy and the inventory-rationing policy. Finally, we use the customer-choice model to characterize the demand-induction and demand-cannibalization effects.


Scrub typhus is an acute, febrile illness caused by Orientia tsutsugamushi infection and it is one of the main causes of acute febrile illness in the Asian-Pacific region. The incidence of scrub typhus has been significantly increased in Korea during last 10 years. Although early diagnosis and proper antibiotic treatment are important to prevent severe complications, the clinical discrimination of scrub typhus from other undifferentiated fevers, such as leptospirosis or dengue fever, is often very difficult. In addition, an effective vaccine has not yet been developed. As a novel diagnostic and vaccine target for scrub typhus, we described surface cell antigen (sca) family genes encoding autotransporter proteins found in the genome of O. tsutsugamushi. The molecular characteristics and recent findings on the bacterial genes were introduced in this letter.


The laser assisted micro structuring of thin films especially for electronic applications without influence the functionality of the multi-layer system e.g. due to melting products is a challenge for the laser micro machining techniques. The P2 scribing of copper indium gallium selenide (CIGS) solar cells on stainless steel carrier foil was studied using shockwave- induced film delamination (SWIFD) patterning. The delamination process is induced by a shock wave generated by the laser ablation of the rear side of the carrier foil. In the present study UV nanosecond laser pulses provided by a KrF excimer laser were used to induce the SWIFD process. The morphology and size of the achieved thin-film structures were studied in dependence on various laser irradiation parameters by optical and scanning electron microscopy (SEM). Furthermore, the materials composition after the laser patterning was analyzed by energy dispersive X-ray spectroscopy (EDX). The temporal sequences of processes involved in the SWIFD process were analyzed with high speed shadowgraph experiments. The results of the present study shows that in dependence on the laser parameter used a large process window exist in which the CIGS thin film can be removed from the substrate without visible thermal modification of the CIGS thin film.


Early Recurrence After AF Ablation. Background: Atrial tachycardia (AT) commonly recurs within 3 months after radiofrequency catheter ablation for atrial fibrillation (AF). However, it remains unclear whether early recurrence of atrial tachycardia (ERAT) predicts late recurrence of AF or AT.


galvanic particulates comprising a first conductive material and a second conductive material, wherein said first conductive material and said second conductive material are exposed on the surface of said particulate, wherein the particle size of said particulate material is from 10 nanometers to 100 microns, wherein the second conductive material comprises from 0.01 percent to 10 percent, by weight, of the total weight of said particulate material, and wherein the difference of potential standards first conductive material and the second conductive material is at least 0.2 V.


Abstract A 13C-NMR study of the reaction between ethylene glycol or 1,2-propylene glycol with diphenylmethane-4,4′-diisocyanate is reported. Assignation of -CH2-, -NHCOO-, and -CH3 groups was made and their concentration dependence on reaction time established. On the basis of these data, the rate constants for different reactions were calculated. It was found that the primary groups of 1,2-propylene glycol are more reactive than the secondary -OH group, and that ethylene glycol is more reactive than 1,2-propylene glycol. Side reactions at low temperature and without catalyst do not take place.


Potato is one of the most important staple crops in both developed and developing countries of the world. Potato genetic resources are a prerequisite for potato breeding in both conventional and genetic engineering programmes. Cryopreservation has long been considered an ideal means for the long-term conservation of plant genetic resources. This review provides comprehensive information on variously novel cryogenic techniques that have been developed since 1990. Factors affecting the success of cryopreservation of potato shoot tips are analyzed and discussed. Evidence of morphological and molecular analysis demonstrates that plants regenerated from cryopreserved shoot tips are genetically stable. Efficient elimination of potato viruses by cryotherapy of shoot tips provides an alternative method for virus elimination. Thus, the materials can be simultaneously prepared for virus elimination and long-term preservation. Routine application of cryopreservation of shoot tips for the long-term preservation of potato genetic resources has already started in Germany, Peru, Czech Republic and Korea. Speciesand cultivar-specificity has to be taken into account for much wider application when cryoprotocols are to be developed. Fundamental studies on mechanisms by which potato shoot tips withstand freezing in liquid nitrogen would help solve this problem. _____________________________________________________________________________________________________________


In this paper, we present a face and gesture recognition based human-computer interaction (HCI) system using a single video camera. Different from the conventional communication methods between users and machines, we combine head pose and hand gesture to control the equipment. We can identify the position of the eyes and mouth, and use the facial center to estimate the pose of the head. Two new methods are presented in this paper: automatic gesture area segmentation and orientation normalization of the hand gesture. It is not mandatory for the user to keep gestures in upright position, the system segments and normalizes the gestures automatically. The experiment shows this method is very accurate with gesture recognition rate of 93.6%. The user can control multiple devices, including robots simultaneously through a wireless network.


Background Hibbard (2007) conducted a qualitative interview study of 30 experienced non-native practitioners of the Native American sweat lodge ceremony. The essential purpose of the sweat lodge is to provide a place and context for purification, healing, and petitionary prayer, that is, to draw in and incur spiritual favor (Bucko, 1998). Through purposively identifying and interviewing key practitioners (i.e., sweat lodge leaders and senior practitioners), ten subjects were selected from each of three different lodges, representing different traditions and from different parts of the country, including Montana, Texas, and Arizona. Practitioners included 17 females and 13 males, ranging in age from 27 to 65 with an average of 50. The number of sweat lodge ceremonies participated in ranged from 80 to 1000 with an average of 271, and the years of sweat lodge practice ranged from 8 to 33 with an average of 18. The transcribed interview data revealed 184 reports of transpersonal experiences which occurred during an estimated 8,126 ceremonies. A qualitative data reduction and content analysis identified 31 types of transpersonal experience that were reduced to 17 categories. Major categories include: encounter experiences (e.g., experiencing the presence of or communicating with spirit beings), psychoid experiences (e.g., physical spiritistic phenomena and healings), visual phenomena (e.g., seeing lights and forms in the hot rocks), visions; feelings of connectedness, channeling, intuitive knowings about participants, leaving the physical body, sympathetic resonance with the earth, and feeling beyond/greater than one's normal self. (For a complete description of the research method and resulting taxonomy of transpersonal sweat lodge experiences, see Hibbard, 2007.)


NICs are increasingly complex and diverse, offering a wide range of hardware functionality to aid network protocol processing. Harnessing the power of NIC hardware requires the ability to control and reason about a variety of different feature sets in the network stack. Towards this goal, we propose Unicorn, a language for describing modern NICs. Unicorn offers a simple set of abstractions for modeling both NIC functionality and the state of a protocol stack. To evaluate its expressivity and potential, we present a non-trivial model for the Intel i82599 10GbE NIC, and an algorithm that uses graph embedding to optimize the use of NIC hardware in the network stack.


While older children present no greater problem than adults, in that they will cooperate fully in making the required collections, younger children are unreliable and require special appliances. The most generally useful of these is the metabolic bed. Various types of such a bed have been described (Bendix, 1896; Bendix and Finkelstein, 1900; Schabad, 1908; Talbot, 1909; Du Bois, 1911; Howland and Cooke, 1911; Hoobler, 1912; Gerstley, 1930; Hoag, 1932) and others all write of


Landfill leachate produced in the Harmandali Landfill in Izmir in Turkey was characterized and chemically treated to examine chemical oxygen demand (COD) and color removal efficiencies. The leachate was coagulated adding various doses of an organic flocculant (DEC). Chemical oxidation was carried out using Fenton's reagent. Powdered activated carbon was used for adsorption to achieve improved COD and color removal in chemically treated leachate. The maximum removal efficiencies of 79% in COD and 98% in color were achieved by Fenton reagent and lime addition (at doses of 2,500 mg/L H2O2 + 2,500 mg/L FeSO4·7H2O2). The best DEC dose was found to be 4,600 mg/L, and COD and color removal efficiencies varied between 60–65% and 82–93%, respectively. A COD removal of 49% and a maximum color removal of 96% were obtained by lime slurry addition. Among the leachate samples, the highest COD and color removal was obtained using the Fenton's oxidation. Activated carbon adsorption tests indicated that the color paramete...


Falling through Life and Dance aims to discuss falling "as a reassuring, creative and life-enhancing force" (p. 2) and to engage with gravity's many possibilities in all its unexpectedness. It invites readers to join the author in an investigation of falling with a spirit of curiosity, intent, and reverence, while challenging the Western assumption that falling is a negative experience. In so doing, Emilyn Claid, the acclaimed experimental choreographer, academic, director, and psychotherapist, delivers a diverse range of ideas linked through the theme of falling. Her ethnographic approach draws together multiple voices. Claid has gathered experiences from dancers, artists, and writers that surprise, invigorate, upset, and inspire the reader's understanding of falling. The perspectives in this book are so diverse that the book is difficult to describe. The book itself exemplifies the fact that there is no one way to think about falling. Reading Falling through Dance and Life is like falling again and again— physically, emotionally, and conceptually. The book treats subjects such as identity and risk as physical, social, and emotional falling. Claid analyzes the performance work My Sex, Our Dance (1986) created by Lloyd Newson and Nigel Charnock, alongside interviews with Lloyd Newson in the section titled "Sex in Crisis" (pp. 127–31). The book also covers ideas related to falling and accidental death in performance in the section "Sholiba" (p. 105). In the section "April 2020," Claid describes the political changes in the UK, including COVID 19, in what begins to feel like a free fall into precarity (p. 96). Due to the broad range of topics and approaches to thinking and feeling falling, this book will appeal to students, researchers, and artists interested in movement, falling, and engagement with gravity. I found comfort in the familiar dance language in the book; however, Claid draws on the vast experience she has in performance to widen the accessibility of this book beyond dance. The language and tone move beyond Western theatrical


This chapter surveys the existing representative work in both sensor-actuator and actuator-actuator coordination. Sensor-actuator coordination deals with establishing data paths between sensors and actuators, and can be used for sensor deployment. Actuatoractuator coordination includes robot coordination for sensor placement, dynamic task allocation, selecting best robot to respond to reported event, robot dispersion, boundary coverage, and fault tolerant response. In coordinated actuator movement problem, actuators are moved to desired locations to save energy in long-term communication tasks where the traffic is sufficiently regular and large in volume to warrant nodes expending energy for moving. A recent study on coordination among flying robots is introduced in the end. 9.1. Sensor-actuator coordination The collaborative operation of sensors enables the distributed sensing of a physical phenomenon. In WSNs (wireless sensor networks), the sink (base station) performs the functions of data collection, processing and coordination. In WSANs (wireless sensor and actuator networks), both sensor-actuator and actuator-actuator coordination are required. After sensors detect an event that has occurred in the environment, the event data is processed (e.g. aggregated with reports from nearby sensors) and transmitted to the actuators, which gather, process, and eventually reconstruct the characteristics of the event. The process of establishing data paths between sensors and actuators is referred to as sensor-actuator coordination [MPGA07]. Sensor-actuator coordination provides the transmission of event features from sensors to actuators. Sensors and actuators coordinate also for some other tasks, such as sensor placement or improving connectivity. Akyildiz and Kasimoglu [AK04] did the first comprehensive analysis on both sensoractuator and sensor-sensor coordination. There are few main requirements on the communications in sensor-actuator coordination [AK04]. The communications between sensors and actuators in WSANs require energy efficiency to prolong the lifetime of the network. In some real-time applications, e.g., detection of fire, the communication traffic is typically delay sensitive. Therefore, sensor-actuator communication should support real-time traffic in these applications. The sensor-actuator communication is also required to ensure ordering of event data reported to the actuators. For example, suppose there are two sensors reporting two different events to a common actuator. These two events may


The highly efficient direct catalytic reductive amination of aromatic ketones with diphenylmethanamine is described. Catalyzed by the iridium–monodentate phosphoramidite complex and assisted using additives, this concise and practical route provided chiral amines in high yields and with high enantioselectivity (ee values of up to 99%).


The practice of urban agriculture (UA) is a unique food system model that localizes the production of sustainable, geographically appropriate food. The environmental benefits inherent in UA align with the emerging field of climate smart agriculture (CSA). However, the agroindustry focus of CSA is beyond the scope of most UA initiatives. Instead, we put forward the term climate smart food as a more appropriate framework to examine the environmental impact of food production in an urban context. The purpose of this study, rooted in the recognition of underutilized private urban land resources for UA, is to assess the potential of urban land to grow climate smart food. The Bowness neighbourhood in Calgary, Alberta is used as a case study. A geospatial process of constraint mapping was applied to analyze suitable private land space that could be converted from lawns to cultivated gardens. Using data from a local food cooperative as a benchmark for local urban production capacity, it was determined that six urban farms in Calgary produced roughly 8,200 pounds of food from private gardens in 2016. In the Bowness neighbourhood, 42 percent of the land was held as private turf grass, and produced only about 800 pounds of food. This type of analysis serves to quantify the magnitude of underutilized land within an urban boundary that could produce significant amounts of climate smart food.


Background: Niemann Pick Disease Type C (NPC) is a rare inherited degenerative disorder, which characterises itself predominately in neurological deterioration and there is currently no cure. The age of onset and the progression of the disease varies. Individuals who present symptoms during childhood hold a more aggressive form of the disease and may not survive to adolescence. The aim of this study is to explore the impact of NPC on patients and develop and validate age-appropriate QoL scales.

Methods: Ten carers were interviewed; 1 interview included a patient. Participants were recruited through the NPC charity and took part in a semi-structured interview based on key areas of QoL: six face-to-face and four over the telephone. The age of patients ranged from 3 to 56 years. Interviews were analysed using content analysis.

Findings: Preliminary findings suggest NPC has physical, psychological, cognitive, social and environmental effects. All participants experienced physical decline, which affected mobility. This caused patients to become frustrated due to the impact this had on their life, especially in teenage and adult patients. The majority of participants who were school age had gone, or were in the process of going from mainstream to specialist school due to cognitive decline.

Current stage of work: Continuing interviews and transcript analysis. Further examination will enable the extraction of relevant items for a prototype scale, firstly for children aged 0-11 years.

Discussion: Results from the interviews will provide a holistic picture of life with NPC and provide a means of measuring QoL.


Hardened steels are widely used when manufacturing components such as gear, bearing, tools and die (Kalpakjian and Schmid, 2001). Its properties of high wear resistance, good corrosion resistance and high surface finish have resulted in this material to be used for producing the components mentioned. Traditionally, grinding has been used to finish machine hardened steel. This approach has some weaknesses in that it is time consuming and only a limited range of geometries can be produced. The development of advanced cutting tool materials, namely polycrystalline cubic boron nitride (PCBN) and ceramic, has led to the improvement in the cutting process of hardened steel. The process of turning hardened steel of 45 HRC and above is known as hard turning.


This article seeks to examine the World War II memorials that were commissioned by the Greek state and other public institutions in Komotini, a city in Western Thrace, as well as their ambiguous reception during the last three decades. It focuses particularly on "The Sword", a memorial that was erected during the years of the Greek military dictatorship (1967-1974) to honour the victims of World War II who gave their lives for their country. It sheds light on the process behind the creation of "The Sword", analysing also its artistic style and visual references in connection with the historical conditions of its creation. The article also considers the recent dispute surrounding the function and aesthetics of the monument, and alternative forms of memorialisation erected in the area in the last decade.


Electric Vehicles (EVs) depend on the charging network for their range and uninterrupted traversal across the city. Such dependency may be exploited by the firms who establish the charging stations. In this paper, we analyse the cartel formation among the firms who establish the charging stations. By forming cartel, the firms can establish individual monopoly at various localities across the city, i.e., the charging stations in a locality is controlled by only one firm. Hence it can manipulate the price as the limited range of the EVs compel them to use the stations only in their respective localities. In this paper, we analyse complexity of deciding on such cartel and we also propose mechanism that can prevent such cartel formation.


Performing the diggings nearby and/under the implantation quota of some existing buildings may trigger on the structural elements and/or over the arrangement site states of efforts or additional deformations, which may diminish the reinforcing capacity and/or loss of local/general stability given certain conditions of induced load. The paper herein presents situation generated by the execution of a section of domestic sewage, near and under the implantation foundation of a retaining wall having the role of maintaining stability of the arrangement site of residential buildings.


The iron(II) complexes of the quadridentate ligand NN′-ethylenobis(salicylideneimine) and its 5-methyl, 5-nitro-, 5-chloro-, 4-chloro-, and 3-nitro-derivatives are high-spin, and have magnetic moments which vary little with temperature. Their moments are lower than commonly found for high-spin iron(II) systems presumably because of distortion and delocalisation effects. Failure to realise the air-sensitivity of these iron(II) compounds has in the past led to incorrect interpretations of magnetic and spectral data. The iron(II) complexes of the bidentate ligands N-phenyl- and N-methyl-salicylideneimine are also high-spin.The reduced magnetic moment of NN′-ethylenebis(salicylideneiminato)manganese(II) has been shown to arise from magnetic exchange. It is oxidised by nitric oxide to a high-spin manganese(III) compound.


Recently, Perdew and Wang have proposed a general spin interpolation formula for the correlation energy of a homogeneous interacting electron gas, Ec(rs, ζ), as a function of the ratio of the average spacing of electrons to the Bohr radius, rs, and of the relative spin polarization, ζ, 0 ≤ ζ ≤ 1, being expressed also in terms of the three functions: Ec(rs, 0), Ec(rs, 1) and αc(rs), where αc(rs) is the spin stiffness of this electron gas. For these three functions, by basing on their correct results, obtained in the rs interval [1, 100] and in the high and low electron density limits (rs 0 and rs ∞, respectively) by other authors, we propose a new analytic interpolation formula, valid at any rs and accurate within 0.6%, 0.3% and 0.8% for Ec(rs, 0), Ec(rs, 1) and αc(rs), respectively. This result is then used to obtain, at any rs and ζ, the correlation energy Ec(rs, ζ), the ground state energy of this electron gas, (E(rs, ζ), and the susceptibility enhancement. For 1 ≤ rs ≤ 100, our numerical results of Ec(rs, ζ) and our conclusions taken on the location of depolarization and crystallization phase transitions are found to be almost the same as those obtained by Ceperley and Alder. Finally, as rs ∞, our approximate formula for E(rs, ζ) converges to the result —1.79186 Ry/rs, independent of ζ, being thus in perfect agreement with that obtained in the Wigner insulator state by Carr et al.

Perdew et Wang ont propose recemment une formule empirique generale pour l'energie de correlation d'un gaz d'electrons homogene Ec(rs, ζ), fonction du rapport de la distance moyenne des electrons au rayon de Bohr rs, et de la polarisation relative du spin ζ, 0 ≤ ζ ≤ 1, etant aussi exprimee en termes de trois fonctions: Ec(rs, 0), Ec(rs, 1) et αc(rs), ou αc(rs) est la raideur de spin de ce gaz d'electrons. Pour ces trois fonctions, en se basant sur leurs resultats corrects, obtenus dans l'intervalle de rs [1, 100] et dans les deux cas extremes de concentrations d'electrons elevee et faible (rs 0 et rs ∞, respectivement) par d'autres auteurs, nous proposons une nouvelle formule analytique et empirique, etant valable pour toute la concentration d'electrons et correcte avec une precision d'ordre de 0.6%, 0.3% et 0.8%, pour Ec(rs, 0), Ec(rs, 1) et αc(rs), respectivement. Puis, celle-ci est utilisee a obtenir, pour tout rs et tout ζ, l'energie de correlation, Ec(rs, ζ), l'energie totale de ce gaz, E(rs, ζ), et l'augmentation de susceptibilite de spin. Pour 1 ≤ rs ≤ 100, nos resultats numeriques de Ec(rs, ζ), et nos conclusions prises sur la localisation des transitions de deux phases de depolarisation et de cristallisation, sont presque les memes comme ceux obtenus par Ceperley and Alder. Enfin, quand rs ∞, notre expression approchee pour E(rs, ζ) converge au resultat —1,79186 Ry/rs, etant independant de ζ et donc en parfait accord avec ce obtenu dans l'etat d'isolant de Wigner par Carr et al.


Basal cell hyperplasia is a rare lesion in the human prostate.5.9,10 Prostatic basal cell hyperplasia has not been reported in the nonhuman primate, although typical, spontaneous, adenomatous hyperplasia of the prostate has been reported in the squirrel monkey, chimpanzee, patas monkey, and calli~ebus.~.~ The 6-year old, male cynomolgus monkey (Macaca fascicularis) was housed at Azabu University School of Veterinary Medicine (Kanagawa, Japan), as part of a control group in toxocologic experiments. The monkey was killed by an intravenous injection of pentobarbital; a complete necropsy was done. A grossly recognizable prostate measured 20 x 20 x 13 mm and weighed 3.0 g. A cut section showed a single, white, firm nodule that measured 3 mm in diameter in the right cranial lobe. Histologically, there was an unusual pattern in the nodular lesion that was demarcated from a circumferential area composed of almost normal and/or atrophic prostatic glands (Figs. 1, 2). The nodule was composed of irregular, solid nests of basal cells and scanty fibromuscular stroma that was cellular but retained its myoid qualities. Nuclei of basal cells were ovoid with finely dispersed chromatin and, occasionally, a


In this research dry matter, total acids (TA), total soluble solids (TSS), TSS/TA ratio, pH, vitamin C, total phenols, flavonoids, non-flavonoids, natural and total invert, in fresh and dried plums, of two plum cultivars ' Elena' and ' Bistrica' , were investigated. There was significant difference between selected cultivars in fresh and dried fruit. ' Elena' showed higher values of dry matter, TSS, TSS/TA ratio, pH and total invert, while ' Bistrica' had higher values of vitamin C, total phenols, flavonoids and non-flavonoids, total acids and natural invert in fresh and dried fruit. It can be concluded that although ' Elena' obviously has some favorable characteristics, cultivar Bistrica has higher content of antioxidant compounds.


The organic–inorganic hybrid metal halide perovskites with different dimensions and diverse architectures are highly attractive materials for optoelectronic applications. However, people know little about the dynamics of their formation processes. Here, we study both experimentally and theoretically the self-assembly formation dynamics of the luminescent colloidal CH3NH3PbBr3 nanocrystals. We have observed their successive transformations from original spherical quantum dots to periodically stacked nanoplatelets when the primitive colloidal nanocrystals with a high concentration were maintained in liquid for a prolonged period of time. A theoretical dynamic collision model by taking into account the popular van der Waals force, the polarization force that is unique for the perovskites, and the electrostatic forces between particle surfaces in the presence of the surface ligands is proposed to explain the self-assembly process of the colloidal CH3NH3PbBr3 nanocrystals. The result reveals that the rather ea...


In this study we made a quite large presentation of some important religious themes of Vinča culture, one the most important civilization of Neolithic period. Based on di!erent discoveries, on literature, as well as on our own experience we have noticed that many of the main religious themes are intercorrelated.So, we have discussed the problem of sanctuaries and cultic inventory, focus on Zorlenţu Mare, Balta Sărată, as well as on Liubcova discoveries.It was discussed and the fragmentation of idols, ritual breaking of sacred e"gies, how it is right to be named, idols or gurines. We referred to the types of masks (human or animal) illustrated by Vinča plastic art. In connection with masks we have approached other problems, such as sacred liquid, symbols of power and social distinctions (cross band, belt, diagonal band etc.).Another important theme is related with birth and sexual organs (phallus, vulva), some artifacts giving us opportunity to present analogies or similar depicting manner.Vinča plastic art also re#ect the theme man-bird, bird, #ight (idol or amulets of Zorlenţ type, with anthropomorphic and ornithomorphic attributes). Dance and music are part of sacred, expressed through alto relief manner of rendering feminine characters on Zorlenţu Mare pots; ocarina discovered at Liubcova can be considered as one of the earliest musical instruments in the area.We did not avoided elements related with magic, but we have underlined that is quite di"cult to make di!erence between the white and the black magic practices, based on artifacts from Zorlenţu Mare, Gornea, or Balta Sărată.Another topic was related to the symbols and signs discovered on several objects related with sacred: idols, pots, altars, table/altars, candles, sacred house, tablets, plates, discs, buttons, and breads. Analogies and similarly discoveries have been presented with reference to our database, Scrierea (Word), as well as the Danube script. Analyzes of di!erent artifacts has underline other important themes, such as sacred marriage, oranta (worship position), throne etc.Most of the religious themes of Vinča culture as in other civilizations are related with events of humans and cycles of nature, sacred and profane being in an inextricably dependence.


melanoma, and the two relatively innocent mimickers, granuloma pyogenicum and the chronic infected 'jigger' (Tunga penetrans infestation). It will be apparent to any medical worker in Africa how difficult it may be to confidently diagnose these conditions and also how important it is, before excision or drastic surgery is performed, to be sure with which one of the conditions one is dealing. I t is the purpose, therefore, of this paper to present some clinical and pathological observations, which we hope may provide some help to both surgeons and pathologists working in Africa or other developing countries where these problems exist.
