A number of recent studies indicate that, under the oxygen rich conditions of oxidation catalysis, some transition metal catalysts may be covered by thin oxide overlayers. Moreover, it has been suggested that such "surface-oxide" layers are catalytically active, possibly more active than the pure metal surfaces as was traditionally assumed. This contemporary picture can be traced back to Ag catalysis, where over 30years ago it was suggested that the top layer of Ag(111) reconstructed to an epitaxial Ag2O like overlayer upon exposure to oxygen [Rovida et al., Surf. Sci. 43, 230 (1974)]. Extensive experimental work, including scanning tunneling microscopy studies in which the oxide was apparently imaged with atomic resolution, as well as density-functional theory calculations, largely confirmed this interpretation. However, a review of published experimental data and new density-functional theory results presented here indicate that previous conclusions are significantly incomplete and that the structure of...

After years of political stalemate on the issue of end-of life medical care in Israel, the Knesset enacted the Dying Patient Law in 2005. This Article argues that the new law manifests a paradigm shift in the normative framework regulating end-of-life treatment in Israel, from a patient right approach based on the principle of autonomy, to a physician duty approach based on the principle of the sanctity of life. In so doing the law created a complex web of formal procedural rules and culturally unique legal artifices, which amount to a maze of medicolegal technocracy. The technocratic maze conceals substantive restrictions on rights to patient autonomy which had been recognized in the former case law in relation to the withholding and withdrawal of medical treatment. In particular, under the new law, the request of a competent patient to withdraw artificial respiration may not be respected, and the advance directives of an incompetent patient to withhold artificial nutrition are of no effect. Beyond a question of constitutionality, the Article suggests that the underlying approach of the law to death and dying is an unskillful response to the challenges that have arisen from life extending technology.


There has been considerable interest in development of scholar search engines. A disadvantage of current scholar search engines is that they have not explored the relationship among theses fully. A novel scholar search engine is proposed here to fill this gap, which can detect different topics hidden in a large volume of theses to help researchers find their interested theses easily. A new community detection algorithm in citation networks is proposed here to achieve detecting topics. This algorithm has time complexity O(c*n) in a sparse citation network, where n is the number of nodes, and c is related to the average degree of nodes and the initial number of communities. Initial experiments show that this algorithm produces effective result on a standard test dataset.


Electronic cigarettes are at the center of much controversy concerning their safety relative to conventional cigarettes. This study investigates the effect vaping electronic cigarettes, compared to smoking conventional cigarettes, has on the percentages of carbon (C), oxygen (O) and nitrogen (N) that makeup a nitrocellulose filter (13 mm diameter, 5µm pore size), and serves as a basic index of the relative impact vaping and smoking have on the respiratory tract. A peristaltic pump (400 ml/min) is used to impact air (n=4), vape (n=4) or smoke (n=4) onto nitrocellulose filters housed inside an in‐line chamber. These filters were exposed to air, vape or smoke during 45 cycles of a 5 second puff followed by a 10 second rest period. Virgin filters not exposed to air, vape or smoke served as control (n=4). The percentages of C, O and N for each exposed filter were determined using scanning electron microscopy with X‐ray microanalysis. The percentage of C in control filters and filters exposed to air, vape and smoke were 46.3 ± 0.3%, 46.6 ± 0.5%, 45.3 ± 0.2% and 73.5 ± 0.3%, respectively. The percentage of O in control filters and filters exposed to air, vape and smoke were 39.8 ± 0.3%, 39.7 ± 0.6%, 44.5 ± 0.3% and 15.9 ± 0.3%, respectively. The percentage of N in control filters and filters exposed to air, vape and smoke were 9.2 ± 0.2%, 9.2 ± 0.4%%, 9.1 ± 0.1% and 8.2 ± 0.3%, respectively. This study indicates that smoking, but not vaping, significantly (p < 0.001) increases the C to O ratio on the nitrocellulose filter, implying that smokers may be more at risk for development of inflammatory or other respiratory pathology.


This paper provides a fundamental understanding of the unsteady fluid-dynamic phenomena on a cycloidal rotor blade operating at ultra-low Reynolds numbers (Re ∼ 18,000) by utilizing a combination of instantaneous blade force and flowfield measurements. The dynamic blade force coefficients were almost double the static ones, indicating the role of dynamic stall. For the dynamic case, the blade lift monotonically increased up to ±45° pitch amplitude; however, for the static case, the flow separated from the leading edge after around 15° with a large laminar separation bubble. There was significant asymmetry in the lift and drag coefficients between the upper and lower halves of the trajectory due to the flow curvature effects (virtual camber). The particle image velocimetry measured flowfield showed the dynamic stall process during the upper half to be significantly different from the lower half because of the reversal of dynamic virtual camber. Even at such low Reynolds numbers, the pressure forces, as opposed to viscous forces, were found to be dominant on the cyclorotor blade. The power required for rotation (rather than pitching power) dominated the total blade power.

There has been an enormous progress in the field of electromagnetic phenomena associated with earthquakes (EQs) and EQ prediction during the last three decades, and it is recently agreed that electromagnetic effects do appear prior to an EQ. A few phenomena are well recognizedas being statistically correlated with EQs: one is the lithospheric radio emission in the ULF (ultra-low frequency, f<1Hz) range, and the second is ionospheric perturbation not only in the lower ionosphere as seen by subionospheric VLF (very low frequency, 3kHz<f<30kHz)/LF (low frequency, 30kHz<f<300 kHz) propagation but also in the upper F region as detected by ionosondes, TEC observations, satellite observations, etc. In addition to the above two phenomena, there have been several not-well-understood effects in possible association with EQs in the frequency ranges of ULF, ELF (extremely low frequency, 1Hz<f<3kHz) and VLF:(i)ULF/ELF transients (or Q bursts), (ii) anomaly in Schumann resonance (SR), (iii) ULF magnetic field depression, (iv) EQ effect on Pc1 pulsations, (v) VLF electromagnetic emissions, (vi) EQ effect on VLF/ ELF whistlers, and (vii) Lightning. The purpose of this paper is to review observational results on those items by different workers. We initially present a case study and then a statistical study for each topic with paying particular attention to its correlation with EQs. All of those effects can be physically explained in terms of two effects: one is likely to be associated with ionospheric perturbation as additional signatures of the lithosphere-atmosphere-ionosphere coupling (LAIC) process ((ii), (iii), (iv) and (vi)) and the other is some kind of discharge phenomena in the atmosphere as by-products of the LAIC process ((i), (v),and (vii)).Then, we can describe possible explanations (or modeling) ever proposed for each item, even though those models are all at the stage of hypothesis and not well proven by https://doi.org/10.33665/IJEAR.2019.v06i02.001 International Journal of Electronics and Applied Research (IJEAR)vol. 6, issue 2, Dec 2019 Online (http://eses.net.in/online_journal.html) ISSN 2395-0064 _____________________________________________________________________________________ Copyright @ESES IJEAR 2 observations. Further studies of these phenomena help us better understand the LAIC mechanism of our current interest.

Abstract: The aboveground part of Alfredia drooping is a source of vegetable raw materials with a nootropic effect. The purpose of the research is to develop the technology of polyfraction dry extract (polyextract) alfredia, a product that is stable during storage and does not contain ethanol. We used liquid extracts from the lower petiole leaves of alfredia as objects of research. They were obtained by sequentially extracting the same portion of raw materials 95%, 70%, 55%, 40%, 30%, 25% ethanol and purified water. To obtain dry extracts stable during storage, we used the technology of adsorption of liquid extracts on non-hygroscopic excipients (lactose, sodium croscarmellose, primogel (sodium carboxymethyl starch), polyplasdon Ultra). This allowed us to prevent dampening of the substance-extract complex, improve solubility and release of biologically active substances from their complexes. The technology of dry polyfraction extract was developed on the basis of seven liquid extracts from the lower petiole leaves of Alfredia cernua as a result of the conducted research. We have carried out the selection of an auxiliary adsorbent (polyplasdon Ultra) for liquid extracts of alfredia (extractants: ethanol 95%, 70%, 55%, 40%, 30%), absorbing up to 350% of extracts and releasing about 90% of the flavonoid complex when dissolved in purified water at a temperature of 37 ° C in 45 minutes. The composition of Alfredia polyextract was established. Extracts (extractants: ethanol 95%, 70%, 55%, 40%, 30%), adsorbed on polyplasdon Ultra, and water dried extracts (extractants 25% and purified water) must be mixed in the ratio 0,6:1,2:3,8:4,6:3:2:1,7, accordingly. The dose of alfredia dry polyextract for a single dose was determined - 1.41 g.

The cis-enol forms of -diketones are stabilized by the action of strong intramolecular hydrogen bonding that mediates attendant protontransfer processes. One of the simplest members of this class of compounds, acetylacetone (H C-CO-CH -CO-CH ), has been demonstrated (both experimentally and theoretically) to possess an asymmetric equilibrium geometry with the two equivalent enol tautomers of the  A ground electronic state separated by a barrier of finite height. In contrast, recent ab initio calculations have suggested that the less-studied  B manifold supports a symmetric (C v) minimum energy configuration. This excited-state structure would imply the presence of a low-barrier hydrogen bond (LBHB), in which the hydrogen is dislocated to a position equidistant from the two oxygen atom centers. Resonance Raman spectroscopy has been used to explore the prediction of an LBHB in acetylacetone and to elucidate the structural changes incurred by electron promotion. Vapor-phase measurements were performed at five discrete excitation wavelengths, chosen to span the absorption band ( ! #"$ nm) as well as pre-resonant and non-resonant portions of the spectrum. The acquired data displayed marked differences in their vibrationally-resolved intensity patterns. As the incident frequency was tuned toward resonance, vibrations involving distortion of the chelate ring were enhanced, whereas modes localized on the methyl groups did not exhibit significant enhancement. In resonant and pre-resonant spectra, numerous overtone and combination bands were observed in the % "$ #& '( *)+&*& cm , and -/.*&+&+& cm , regions. These results are indicative of large geometry changes taking place upon 0 excitation, with theoretical analysis based on a time-dependent formalism for Raman scattering being utilized to quantify and interpret such structural modifications.


land's 2011 floods which saw the closure of the Ports of Brisbane, Gladstone, Bundaberg and Port Alma for the duration of the floods and significant damage done to navigation aids such as buoys and beacons. Extreme weather conditions also have the potential to result in unsafe or difficult sailing conditions and an increase in fuel consumption. With respect to mitigation, contributors discuss a range of mitigation options ranging from technology to systems to vessel design and operational improvements and market-based measures such as incentive, rebate, compensation and credit trading or emissions trading schemes. Given the global character of shipping, specific attention is also paid to the potential mitigation costs and impacts for developing countries. While these mitigation issues are given weight, the focus of this volume is also on ensuring that in addition to controlling emissions from shipping, sufficient attention is given to adapting to a range of climate change scenarios. Climate change has significant implications for transport infrastructure and services, especially ports, and contributors highlight the need for appropriate adaptation response measures. Based on real-world examples, contributors warn again mal-adaptation and provide guidance on adaptive measures that ports in particular can adopt to respond to climate change and actions they can undertake towards climate-proofing port and related maritime infrastructure. Presenting a mix of practical adaption and mitigation discussions alongside more technical background information, this volume is presented in short chapters which are accessible to both non-mariners and those with only a passing familiarly with the climate science. Considering a range of issues across vessel design, transport operations and infrastructure development, the contributors to the volume emphasise the importance of taking a proactive approach to transport planning decisions. Contributions to the volume, from the United Nations Framework Convention on Climate Change, International Energy Agency and the International Maritime Organisation, sit comfortably alongside those provided by climate change researchers, international shipping experts and transport planners. This book will be of interest to planners with an interest in transport, port or coastal planning or in climate change more generally. Contributions and case examples within the volume are provided from the USA, Europe and South Africa. However, given the international focus of shipping and strong interdependency of the international ports and shipping network, the absence of Australian examples in this volume is relatively unproblematic and much of the information presented is transferrable to an Australian context. Indeed, given Australia's reliance on international shipping, the international focus is appropriate and reflects the truism that we are all in the same boat as far as climate change is concerned.


Summary.  Background: Although platelets are anucleated cells, they express several transcription factors that exert non‐genomic functions, including the positive and negative regulation of platelet activation. NF‐κB is a major transcriptional regulator of genes involved in survival, proliferation and inflammation. Objective: Because platelets play a critical role not only in hemostasis, but also in inflammation and tumor progression, we evaluated the role of NF‐κB in platelet physiology. Results: Immunofluorescence, Western blotting and ELISA studies revealed that platelets express IκBα and NF‐κB, and that stimulation with thrombin triggers IκBα phosphorylation and degradation and the binding of platelet NF‐κB p65 subunit to synthetic olignoucleotides containing the consensus sequence for NF‐κB. Two specific unrelated inhibitors of NF‐κB activation, BAY 11‐7082 and Ro 106‐9920, reduced PAC‐1 and fibrinogen binding to integrin αIIbβ3 and restricted platelet spreading on immobilized fibrinogen. Both inhibitors impaired aggregation mediated by ADP, epinephrine, collagen or thrombin, but not arachidonic acid. ATP release, TXB2 formation, P‐selectin expression, ERK phosphorylation and cPLA2 activity stimulated by thrombin were reduced in BAY 11‐7082‐ or Ro 106‐9920‐treated platelets. Although bleeding time was not affected, ADP‐induced platelet aggregation was impaired in mice treated with BAY 11‐7082. Conclusions: Our results suggest that NF‐κB may be a novel mediator of platelet responses. The blockade of platelet function by NF‐κB inhibitors might be relevant in those clinical situations where these drugs are being considered for anti‐tumor and/or anti‐inflammatory therapy.

Definite the method for the time that single well becomes effective and water cut risen again sooner or later, the time single well becomes effective depend on the oil reservoir condition ,and the time that water cut risen again depends on the oil extraction level of surplus reserves while polymer flooding.This paper gives the result of the adjustment and evaluates the incremental oil per ton and the surplus reserves recovery ratio of per well carry.This paper is effective on predicting the product oil capacity.


The subject diaphragms are made from individual corrugated sheets which are connected to one another and to framing members with discrete fasteners. Failure of them under load is most commonly due to localized bearing or shear failure at the fasteners. The shear stiffness of the diaphragms depends greatly on the layout and number of fasteners. Formulas are derived for the shear stiffness and for the fastener forces in such diaphragms, which should be applicable where bolts, rivets, screws, or welds are used as discrete fasteners, and where the diaphragm loads are in the working range. The formulas are shown to agree quite well with the results of previous tests by the writer.

Objectives Patient non-attendance at outpatient appointments is a major concern for healthcare providers. Non-attendances increase waiting lists, reduce access to care and may be detrimental not for the patient who did not attend. We aim to produce a model which can accurately predict which appointments will be attended. Setting A teaching hospital in London, UK combining secondary and tertiary care. Participants A set of 9.6 million outpatient appointments between April 2015 and September 2019 including all ages and specialities. Primary and secondary outcome measures Area under the receiver operating characteristic curve (AU-ROC) for prediction of outpatient appointment non-attendances. Results The model uses 27 predictors to achieve an AUROC score of 0.768 (95% CI: 0.767-0.769) and accuracy of 89.2% (95% CI: 89.16%-89.24%) on test data. We find that the waiting period between booking and the appointment, the patient's past attendance behaviour, and the levels of deprivation in their local area are important factors in predicting future attendance. Conclusion Our model successfully predicts patient attendance at outpatient appointments. Its performance on both patients who did not appear in the training data and appointments from a different time period which covers the Covid-19 pandemic indicate it generalized well across both face to face and virtual appointments and could be used to target resources and intervention towards those patients who are likely to miss an appointment.


We demonstrate a low series resistance contact of gold (anode)/zinc-phthalocyznine in a reverse organic photovoltaic device aided by oxygen plasma treatment. The power conversion efficiency appreciated from 0.2% to 2.13%, post O2 plasma treatment, predominantly due to the reduction in the series resistance of the device. A depth profile of zinc from x-ray photoelectron spectroscopy study revealed a gold layer with graded zinc composition, instead of pure gold, to be an efficient hole-collector from the organic interface. The zinc alloying of the gold layer has clearly been promoted by the oxygen plasma treatment.


ABSTRACT An investigation into the efficient use of water as a solvent and the influence of extraction temperature, extraction time, water to leaf powder ratio, particle size, and extraction cycle on the nutraceutical and antioxidant profile of aqueous mulberry leaf extract were conducted using a single-factor experiment approach. All the assessed extracting parameters showed a significant effect on the nutraceutical compounds and antioxidant properties. The optimum extraction conditions were as follows: extraction temperature of 70°C, extraction time of 40 min, water to leaf powder ratio of 40:1 ml/g, particle size of 25 µm, and two extraction cycles. Based on these optimal conditions, chlorogenic acid (62.10 mg/g), caffeic acid (32.21 mg/g), kaempferol-7-O-glucoside (19.30 mg/g), quercetin-3-rutinose (15.69 mg/g), quercetin-3-O-glucoside (32.38 mg/g), kaempferol-3-(6-rhamnosylglucoside) (42.52 mg/g), quercetin-3-(6-malonylglucoside) (65.19 mg/g), kaempferol-3-glucoside (66.27 mg/g), kaempferol-3-(6-malonylglucoside) (50.18 mg/g), 1-deoxynojirimycin (15.58 mg/g), and gamma-aminobutyric acid (5.05 mg/g) were obtained. The optimal aqueous extract had high antioxidant properties of 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (39.98 mM/g), cupric ion reducing capacity (58.93 mM/g), 1,1-diphenyl-2-picrylhydrazyl (101.33 mM/g), and ferric reducing antioxidant power capacity (233.77 mM/g) of dried mulberry leaf extract.

For many years, Henry Stapp and I have been working separately and independently on mind-centered interpretations of quantum theory. In this review, I discuss his work and contrast it with my own. There is much that we agree on, both in the broad problems we have addressed and in some of the specific details of our analyses of neural physics, but ultimately we disagree fundamently in our views on mind, matter, and quantum mechanics. In particular, I discuss our contrasting opinions about the nature and randomness of quantum events, about relativity theory, and about the many-minds idea. I also suggest that Stapp's theories are inadequately developed.

The Covid-19 pandemic has put stress on the healthcare system around the world and has had an impact on people's access to healthcare. This study aims to underline the activities at the Rabat Children's Hospital (HER), during the year 2020 which experienced a state of health emergency due to the Covid-19 pandemic.
Material and methods: We have listed the data from the admission and billing service, about the activities of the hospitalization department of the children's hospital, Rabat. Data was entered on WPS and analyzed by Jamovi software 1.6.23. We also calculated some performance indicators: Average occupancy rate, average length of stay, and bed turnover interval (BOR, LOS, and BTOI). Results: We distinguished between services providing « urgent care » (intensive care unit ICU and emergency rooms ER) and those providing « non-urgent care » (pediatry and surgery) department. The mean number of hospital admissions (NHA) was around 8123 + /− 3942. The average BOR, LOS and BTOI were respectively 72.0 days (SD: 32.6), 66.83 days (SD: 2.68) and 3.89 days (SD: 4.34).
Conclusion : The COVID-19 pandemic had an impact on our hospital activities, disturbing its normal functioning. This study tried to have an overview on the current situation and should lead to other studies in the future, allowing a better managmnt of our hospital.


Developments in telecommunications and IT have the potential to reduce traffic growth, and hence congestion, as alternatives to travel, in the form of teleworking, videoconferencing, and teleservices, are expanded, and as IT improves business logistics and the utilisation of road goods vehicles. There has been considerable recent interest in these possibilities, and the present report seeks to quantify their potential impacts for the first time. It uses the Government's new revised National Road Traffic Forecasts, which were published in October 1997, to consider what would happen to congestion in the absence of the increased use of telecoms. The report concludes that increased use of telecoms will lead to a significant reduction in traffic growth. Under the Report's optimistic scenario, traffic growth would be more than halved. Because congestion costs rise more rapidly than do traffic levels, this means that the growth in congestion could be cut by up to 70 per cent with greater use of telecoms. (A)


The global popularization of electric vehicles (EVs) poses an opportunity for the construction of micro-grid and smart community within energy internet on competent the massive and concentrated energy switching and routing in the local environment. Smart EV charging is a promising solution to manage EV charging load that relies on an accurate prediction of EV charging demands. Evaluation of household EV charging demand is a primary factor for designing smart EV charging solutions on household and neighbourhood level. However, this subject has not been adequately discussed in the research community. In this paper, several widely used machine learning algorithms are adopted to forecast the household day-ahead EV charging occurrence-time and the "no charge" day respectively. The performance of the algorithms are evaluated and compared. A two-layer hybrid stacking ensemble learning method is also proposed, that combines multiple machine learning algorithms. This proposed model is demonstrated to achieve a better classification performance than individual algorithms.

The aggregation of phosphoprotein P of Chandipura virus (CHPV) and its interaction with viral leader (le) RNA in aqueous buffer and 40% ethylene glycol (EG)-buffer have been characterised using two single tryptophan (Trp/W) mutants W105F and W135F. The longer rotational correlation time [(θC)T] originating from overall motion observed at 300 nM concentration conforms to a globular structure of the monomer of WT and both the mutants. The (θC)T values also indicate that W135F does not form a dimer at 1500 nM concentration; while a dimer with disordered structure is predicted for both WT and W105F. The complexes of WT and W105F with le RNA at monomeric and dimeric conditions are indicated to have tight core packing. Dimerization and complex formation at both the concentrations enhance the correlation time arising from the localised motion of Trp side chain [(θC)S] for WT and W105F predicting hindered localized rotation of Trp 135. Comparative protein modelling and molecular dynamics (MD) simulations using the amino acids domain ranging from 105–168 of the full length CHPVP based on the vesicular stomatitis virus phosphoprotein (VSVP) also indicate that formation of dimers are more feasible for WT and W105F compared to W135F.


Abstract Since Japan is a major disaster country, various means for delivering disaster information are used at the time of disaster. However, the conventional disaster information is for the mass, and does not consider individual circumstances and contexts. Therefore, some residents cannot grasp their surrounding dangers properly, and thus fail to escape from disasters. In this paper, we propose a new Web application CANDLE (Crowd Assisted Navigation for Disaster Localization and Evacuation), which visualizes disaster information adapted for individuals, and suggests appropriate evacuation actions. CANDLE collects micro disaster reports posted by people in evacuation. It then visualizes the reports on the map, together with macro information provided by local governments and the meteorological agency. Considering evacuation alerts, user's current location, the current time, and the collected micro reports, CANDLE suggests appropriate evacuation actions to the user. As a result, it is expected that the evacuation awareness of the user is improved significantly, and that the user can take a faster and more appropriate evacuation action.

Physical education (PE) teachers' leadership plays a critical role in enhancing students' learning. Each PE teacher leadership style implies a critical meaning of how a class reaches its goals and objectives effectively. Transformational leadership initially was proposed by Burns (1978). Daft (2008) defined transformational leadership as "characterized by the ability to bring about significant change in followers and the organization" (p. 356). The expectancy value theory focuses on two critical aspects: an expectation of being successful in a current or distant task and the value placed on having a value for doing the task. The purpose of this study was to examine the effect of PE teachers' transformational leadership on middle school students' expectancy-value. Transformational teaching questionnaire (Beauchamp et al., 2010) and expectancy-value questionnaire (Duncan & Tammen, 1989) were employed for this study; a total of 16 items were used. The participants included 295 middle school students from three private middle schools located in the southwestern area in the USA and 262 questionnaires were used for the data analyses. Collected data were analyzed by descriptive, exploratory factor analysis and regression using the SPSS 25. According to single regression, transformational leadership had a positive impact on students' expectancy-value. Based on multiple regression, intellectual stimulation was a common factor that affected students' expectancy-value positively. The results of the study support the importance of transformational leadership which used a means of enhancing middle school students' expectancy-value in PE. Moreover, this study indicated that transformational leadership facilitates teaching and students' learning in PE. Thus, it is recommended that PE teachers be able to understand and display appropriate leadership, in particular transformational leadership.


Title: Chemotherapy induced changes in Wilms tumor: An institutional experience 20 cases of wilms tumor were treated with SIOP protocol using preoperative chemotherapy with vincristine and actinomycin D, the response of the tumor by decrease in size was assessed by imaging and histopathological response was also assessed.10 cases were of wilms were treated using the NWTS protocol with upfront nephrectomy and used as controls. Gross size reduction was seen with SIOP protocol and significant response of epithelial and stromal elements were noted, as well as blastemal nodules. Diffuse anaplasia did not respond to chemotherapy. This evaluation helps to define the susceptibility of different elements in wilms tumor to chemotherapy.


Working capital is part of the total capital employed by a company and is often defined as the difference between shortterm liabilities and short-term assets. Practically speaking, it is the cash required to run the daily, weekly and monthly operations of a business. Therefore, it is the process of managing the short-term assets and liabilities so that a firm has sufficient liquidity to run its operations smoothly. The efficiency of working capital management can be measured through a variety of methods and ratios. This paper compares various spinning industries in Coimbatore city by using ratio analysis and for which the secondary data has been used.

Abstract The Ermlitz manor house near Leipzig includes an enfilade of five parlours, decorated in the 1770s with 310 m2 painted, textile wall hangings. The outcomes of the first three years of a long-term conservation project led by the Conservation Department of the Academy of Fine Arts Dresden are reported. The pilot phase ended in 2011 with the remounting of the treated wall hangings of the Red Parlour. Solutions developed for mechanical surface cleaning, the consolidation of the highly water-sensitive paint layers and the mordant gildings, the conservation of the canvases (thread-by-thread tear mending, inserts, and local supporting with BEVA-coated polyester gauze), and the remounting of the wall hangings with a newly-developed mounting-system based on neodymium-iron-boron (NdFeB) permanent magnets and hook-and-loop fastener are described.


THE following case is reported on account of the rarity of the type of tumour at this site and the light which this individual tumour sheds on the origin of such neoplasms. Moreover, the patient's symptoms led to her treatment for a very different trouble, although the laryngeal condition could have been diagnosed by simple laryngological examination.


We quantify the robustness of the semantic segmentation model U-Net, applied to single cell nuclei detection, with respect to the following factors: (1) automated vs manual training annotations, (2) quantity of training data, and (3) microscope image focus. The difficulty of obtaining sufficient volumes of accurate manually annotated training data to create an accurate Convolutional Neural Networks (CNN) model is overcome by the temporary use of fluorescent labels to automate the creation of training datasets using traditional image processing algorithms. The accuracy measurement is computed with respect to manually annotated masks which were also created to evaluate the effectiveness of using automated training set generation via the fluorescent images. The metric to compute the accuracy is the false positive/negative rate of cell nuclei detection. The goal is to maximize the true positive rate while minimizing the false positive rate. We found that automated segmentation of fluorescently labeled nuclei provides viable training data without the need for manual segmentation. A training dataset size of four large stitched images with medium cell density was enough to reach a true positive rate above 88% and a false positive rate below 20%.

The study was correlational as it sought to examine the relationship between liquidity and the firms' viability. From the Pearson Product-Moment Correlation Coefficient technique of data analysis, liquidity had a significant relationship with the firms' financial performance as measured by ROA, but insignificant relationship with the firms' financial performance as measured by ROE and ROCE. Based on the findings, the study recommended among others that, the firms can improve their final bottom-line by proficiently handling their liquid resources.


A nonassociative generalization of the principal fiber bundles with a smooth loop mapping on the fiber is presented. Our approach allows us to construct a new kind of gauge theories that involve higher ''nonassociative'' symmetries.


Few requirements engineering techniques are widely applied in industry. This can–at least to some extent–be attributed to lack of dedicated guidance, tool support, and technique integration. In this paper, we describe dedicated tool support and guidance for rationale-based use case specification, which we incrementally derived from several students experiments. Through this example, we want to promote student experiments as a good basis for developing and improving guidance material and tool support, hence facilitating technology transfer.

Children's coloring books contain line drawings which a child can fill in with a crayon to produce colored pictures. Two dimensional colored areas can be produced on a raster display by an analogous method. After drawing a closed curve with line drawing commands, the graphics system can fill the area bordered by the curve. This paper presents an algorithm for filling in areas of any size or shape. The area may be filled with any color, texture, or "wallpaper" pattern. The algorithm is simple, flexible and efficient, optimized to take advantage of the the memory organization of most current raster graphics systems.


ESTRO 35 2016 _____________________________________________________________________________________________________ versus 0.4%), and just fell within the pre-defined noninferiority margin of 4.5%. However, in patients with low risk factors like suggested by the ESTRO or ASTRO consensus' criteria, there were not statistically different LLRs in both arms, and also in patients with luminal A molecular subtype the LLR was very low in the IORT arm, about 1%. It was also found that there was no significant difference in the 5-year overall survival rate in two arms, that is, 96.8% in the ELIOT arm and 96.9% in the EBRT arm. For patients with higher risk factors, a new strategy has been now developed, which include a hypofractionated WBI to be given after surgery and ELIOT. The TARGIT-A trial was a multicentric trial. The inclusion criteria were stricter than in the ELIOT trial. It included patients with unifocal small breast cancer with nonlobular histology and tested the concept of risk-adapted single-dose IORT, which was followed by external-beam WBI in patients with additional unfavorable risk factors. The latest published results from the TARGIT-A trial, with a median follow-up of 2 years and 4 months, reported a LRR with IORT of 3.3% and with EBRT of 1.3, meeting the noninferiority margin of 2.5%, set at the outset. Overall, breast cancer mortality in the IORT arm was 2.6% versus 1.9% in the WBI arm. In addition, non-breast cancer deaths were found to be significantly reduced in the IORT arm: 1.4% versus 3.5%, with p = 0.0086. Toxicity and cosmesis were assessed by different methods in the studies, but in any case a favorable outcome has been shown. The comparison between the current standard or alternative PBI approaches for early stage breast cancer with data coming IORT techniques poses a dilemma as to when preliminary results are sufficiently mature to be allow practitioners and patients to consider a new treatment approach as safe. We know that most data from studies of breast conservation therapy have demonstrated the importance of long-term data (up to 20 years) in determining the ultimate efficacy of a treatment. The level 1 randomized evidence produced by the IORT trials show that this technique is very convenient for the patient, effective and has few side effects, rather than any postoperative treatment or procedures. Patients have every right to be offered an informed choice.


The selected plant leaves of P. amboinicus and S. aromaticum (clove) powdered and used for the treatment of Drosophila melanogaster. After days, exactly 10 number of D. melanogaster were introduced into each container along with addition P. amboinicus leaf powders and S. aromaticum (clove) powder in the concentration range of 1g, 2g up to 5g in each separate container. Regular observation was made at every 24 hours interval for 7 days on adult mortality of D. melanogaster. Present study was to investigate the properties of medicinal plant components, for their safety and efficacy. A synthetic insecticide is either not easily available to subsistence farmers or they cannot afford them, the use of natural medicinal plant leaves like S. aromaticum and P. amboinicus which can be easily grown by such farmers. Among the S. aromaticum, higher percentage of mortality rate of D. melanogaster was recorded in 5g.Among the P.amboinicus, higher percentage of mortality rate of D. melanogaster was recorded in 5g.But on a comparative analysis between the leaf powders and P.amboinicus , brought the higher mortality rate of D. melanogaster than S. aromaticum .The above results indicated that the leaf powders P. amboinicus of is very effective in controlling D. melanogaster Physico-chemical analysis and FTIR spectrum analysis of the two powders were also done. Therefore, the present study proves the possibility of using leaf and flower powders as insecticide to control the D. melanogaster. The present study also proved that presence of phytochemicals in two medicinal plant leaves and flower making difference in them. The data were subjected to Linear Multiple Regression analysis; means, standard deviation and correlation coefficient were analysed.

Brain-computer interfaces (BCIs) based on the steady state visual evoked potential (SSVEP) can provide higher bitrates and require shorter training than other BCIs. The oscillating visual stimulus required to elicit an SSVEP can be (depending on the stimulation frequency) annoying for the user and even dangerous since it can trigger photoepileptic seizures. These issues can be surmounted by using high-frequency stimulation (beyond 40 Hz). However, the nature of the SSVEP is such that it decreases with increased stimulation frequency. Conventional spectral methods are not always suitable for detecting high-frequency SSVEPs. In this paper, it is shown that the recently developed phase rectified reconstruction average (PRSA) technique effectively detects SSVEPs elicited by stimulation frequencies between 43 and 46 Hz.


INTRODUCTION
The tension-free vaginal tape obturator (TVT-O) procedure is one of the most commonly used anti-incontinence surgeries, but little is known about its impact on sexual function.

AIM
To evaluate sexual function after the TVT-O procedure at 6 months postoperatively.

METHODS
Fifty-six sexually active women who underwent the TVT-O procedure for severe stress urinary incontinence (SUI) were evaluated using the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) before and 6 months after surgery. The perception of incontinence-related quality-of-life were also evaluated by the short form of the Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) to assess the effect of surgery on incontinence.

MAIN OUTCOME MEASURES
Total score and score for each PISQ-12 item.

RESULTS
The mean total PISQ-12 score did not differ significantly before (24.0 + or - 12.2) and after (23.0 + or - 13.2) (P = 0.194) the TVT-O procedure. Scores for individual items on the PISQ-12 varied, with incontinence-related items improving but others, such as the frequency of achieving orgasm deteriorating for some women. The scores of UDI-6 and IIQ-7 were significantly improved by 6-month follow-up, indicating that the operation successfully resolved the incontinence.

CONCLUSION
Despite successful amelioration of SUI by the TVT-O procedure, sexual function does not necessarily improve in the first 6 months after surgery.


By taking into account all the irreducible representations and their components in the electron-phonon interaction (EPI) as well as all the levels and the admixtures of basic wavefunctions within d3 electronic configuration, the values of the parameters in the expressions of thermal shift (TS) from EPI for the ground level, R level and R line of SrTiO3:Mn4+ have been evaluated; the R-line TS and various contributions to it have been calculated in the low-temperature region. It is found that all the three terms of R-line TS from EPI relevant to the lattice vibration are red shifts. The Raman term is the largest, the neighbor-level term is the second, and the optical-branch term is very small over the range of T≤80 K. The contribution to R-line TS from thermal expansion has been approximately neglected in this work. The very strong EPI relevant to its lattice vibration for SrTiO3:Mn4+ causes its R-line TS to be an unusually large red-shift. Only by taking into account the strong softening of the low-frequency acoustic modes of the lattice vibration at low temperatures, can we successfully explain the variation of R-line TS of SrTiO3:Mn4+ with temperature.

An elasticity solution is obtained to the problem of a thin, laminated, isotropic circular plate under combined transverse and edge loading. The analysis yields an approximate, thin-plate theory which reduces to an exact, closed-form solution when the plate is loaded by edge forces and moments only. The results show that, under edge loading, the stress state is purely biaxial, there being no interlaminar normal or shearing stresses such as are usually present in bulk composite bodies. Further, an estimate of the edge-effect correction which is present when the applied stress distribution does not match the internal stress distribution, discloses no unusual effects due to the laminated structure. Under combined loading, a complex state of in-plane, normal and shearing stresses exists which is coupled through the property variations.


This experimental study has been conducted in the Zanjan University's pilot farm in order to evaluate the yield and yield components of corn and soybean intercropping in deficit irrigation condition. Irrigation levels in main plots were considered at three levels of seven days (control), nine days, and every eleven days interval. The cropping pattern at subplots was as follows: separated plots for corn and soybean monoculture, additive intercropping (100% corn plus 20% soybean), replacement intercropping with 2:2 ratio (50% corn plus 50% soybean). The best corn yield after control group was obtained from every nine day irrigation interval. Moreover, the corn yield was higher in intercropping than monoculture crops. The soybean seeds have not been affected by different irrigation interval and the best yield was obtained from monoculture of soybean, while its have not any significant differences with intercropping yield. At this experiment Intercropping shown superiority on monoculture and every nine day irrigation interval was the best low irrigation method for grain yield in the intercropping.


The salinity tolerance of six annual crop species, wheat, oats, barley, rye, flax and rapeseed, were determined on saline soils that occur north of the Quill Lakes in the northeastern corner of the agricultural area of Saskatchewan. The relative merits of a salt-tolerant grass-legume mixture were also given consideration. The effects of salt stress on spring-sown cultivars became most apparent following exposure to hot, dry summer weather. In contrast, maximum salt tolerance for both winter wheat and winter rye was a function of winterkill. The winterhardiness of both winter annuals was reduced by saline conditions, but winter rye was more adversely affected than winter wheat. Large decreases in seed yield, plant dry weight and height occurred before the effects of increased soil conductivity were expressed for hectoliter weight, 1000-kernel weight, date of maturity, protein content and oil content. Among the spring and winter annual cultivars considered, Bonanza barley and Garry oats demonstrated the gre...


Like the birds that migrate from South to North each Spring, many ophthalmologists regularly make an annual trek to Baltimore, there to attend the meeting of the Wilmer Residents Association. These meetings, initiated several years ago by Alan C. Woods, are now recognized to be one of the finest yearly meetings on the calendar. These meetings are a combination of the formal and the informal, the carefully prepared presentation and the spontaneous comment—all impossible to capture. There can be no compte rendu of the Wilmer Meetings, but a sample of the work done at the Wilmer Institute can be given. Elsewhere in this issue of the Archives are five papers written by Wilmer residents. This sample may arouse in some a desire to read more Wilmer papers. With foresight typical of the Institute, this possibility has been anticipated and provided for. Sixteen bound volumes of the collected reprints of the

The water purification device contains a shell, in which is the bamboo carbon or active carbon. The shell is scattered with water penetration holes densely. People can directly pour unpurified water into the cup, and the bamboo carbon or active carbon in the water purification device can attach impurities or filths, thus purifying the water. The utility model has advantages such as low production and using cost, convenience, simplicity, being beneficial for people's health.


The experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Institute, Gazipur during 2019 to quantify the border effect on rice. The experiment was set in a randomized complete block design with twelve replications. The treatment was non border (T1) and border (T2). Border treatment (T2) had signifi cant and positive infl uence on different parameters of rice. Grain yield and associated yield components improved in border treatment. Border effect was estimated at 8% in respect of grain yield. Increased tillers/hill (18%), fi lled grains/panicle (47%), grain weight/panicle (45%), grain growth (12%) weight of 1000-grain (0.97%), biological yield (4%) and harvest index (4.5%) were observed in border rows. Rice plant both fl owered and matured 3 days earlier in border rows. Carbon input and uptake of N, P, K, S and Zn by rice were found higher values in border treatment. Carbon accumulation increased about 4.4% in border rice. Two lines/rows of rice hill should be excluded for harvesting of plot yield. Otherwise 8% yield will be deducted in actual yield calculation for eliminating the border area effect/border effect (for 2 lines/rows of hills around the plot).

The paper discusses the problems of doing research on rural change in the Baltic States. The past structures and present transition create a new starting point for rural development. The changes taking place in the post-socialist countryside since independence challenge the idea that the countryside will develop along the path of the Western European countryside. Concepts from present rural theorizing must be changed and modified in an interaction between concrete local cases and abstractions and theory to gain a deeper insight into the structures and mechanisms of change. The ontology of critical realism sets the broad basis for the study. Interpretative approaches shed light on the problems of collecting data in a different context than one's own and discursive perspectives highlight some of the reasons why the Baltic countryside are not changing in easy line towards the rurality of the EU. Introduction The Baltic States are no longer an integrated part of the Soviet Union but is reintegrating with the European and global economy. The Baltic rural areas have experienced dramatic changes since the late 1980s. The dismantling of state structures of management and control of farms, the privatisation and restitution of landownership and the sweeping market reforms of the early 1990s disrupted agricultural production in the short term and greatly diminished production intensity in the medium term. Rural areas remain economically depressed and there is a severe lack of both physical and social infrastructure to facilitate development. The main problem for the Baltic countryside is currently the lack of jobs. One of the most pressing struggles in the post-socialist countryside is adapting agriculture to entry into the EU involving increasing farm size, modernising production and reducing employment. As other sectors of the economy might not able to absorb all the people displaced from agriculture, rural diversification is needed with particular emphasis on non-agricultural activities. The aim of my phd-project is to identify and better understand the structures and mechanisms of Baltic rural change in order to discuss problems, possibilities and conditions for diversification of the rural incomes. The ontology of critical realism that reality is not just what we empirically can experience but consists of structures beyond and independent from our immediate experience is the point of departure. Working in a different societal context the challenge is to grasp the structures and powers of importance in this setting. Structures that are not immediately well-known to us. In studying the Baltic countryside the challenge is to understand how another setting and past structures of planned economy change within a context of transition and give another starting point for rural diversification within a new context of a European and global economy. The role of theory in a different setting Regarding the relation between theory and empiri a common view is that theory is applied to order, explain and predict facts. On the basis of theory hypotheses are put forward and tested empirically. The hypothesis of post-socialist rural development is often put forward is that a delay in time separates the level of rural development in Eastern Europe from that in the EU. The scenarios for post-socialist rural change follow the debate on the enlargement of the EU and take a starting point in the effects the accession of new members will have on the European Union. Cheaper agricultural goods and a heavy influx of unemployed rural migrant workers will flood the borders. The underlying assumptions are that the accessing countries will follow the same development as the Western countries have been through of depopulation and intensification of agriculture followed by rural diversification and urbanisation. The rural areas in the developed market economies have diversified as a result of broader socioeconomic transformations and societal modernization often referred to as late modern society or the "post-productivistic era" (e.g. Ilbery & Bowler, 1998). This development has opened up the countryside to new uses giving a foundation for different rural agendas and driving forces for rural change. Connected processes like agricultural restructuring and liberalisation, the introduction of new environmental policies and the immigration of middleclass incomers have created a countryside of multiple functions and hereby set the stage for a more complex relationship to the surrounding world. The rural landscapes are becoming increasingly important for functions related to cultural heritage and as a source of recreation besides their function as a basis for marketable products. Part of the exercise is to test the concepts and trends that dominate the present rural theorizing and studies in Western Europe and place these in the Baltic rural context. In this countryside concepts of marketisation, EU approximation and privatisation are powerful instruments in explaining recent changes in agriculture and the rural economy, including the development of rural entrepreneurship, the emergence of productive farms and the appearance of new processing and service companies (e.g. Tiesenkopfs, 1999). The loss of the economic and cultural importance of agriculture has thrust farmers into a search for diversified and alternative strategies, where the rural and environmental interest of the growing urban middleclass in the metropolitan regions might bring new horizons for rural development like rural tourism and recreation. As Eastern Europe is about to access the EU, the theoretical language of concepts based on Western European examples can help understand, analyse and categorise what is happening. But these concepts are constantly being challenged. There is a need for another, complementary theoretical perspective. One which can help explain other outlets of post-collectivist agrarian reform – small holding agriculture, the decommodification tendency, the system of petty production, the peasantification of households and the way out of agriculture. Rural responses to the challenge of markets have included both an increase in rural "entrepreneurship" and an apparent retrenchment to older forms of production like peasant subsistence farming (Varis, 1998). So instead of simply sticking to the idea that it is only a delay in time separating east and west, a more complex understanding of rural areas must be applied. Time must be viewed in a more complex and qualitative manner. Swain (1999) characterises the post-socialist countries as countries which have ignored the onset of late modernity which was part of the reason for their collapse. Socialist agriculture is a part of a "modern" project with priority on production and industrialisation. The onset of the "late modern" era of diversification away from agriculture characterised by counterurbanisation and consumption landscapes has had a profound impact on the rural societies of Western Europe but how important will that be for the Baltic countryside? The rural inhabitants in the East has experienced other changes in society in the post-war period than countries in the West which leave them with a modern countryside in transition in the late-modern era. The Baltic States are edging into the "post-productivistic era" with a completely different starting point than that of a rural area in a Western European country. The local starting point is characterised by an economy in transition, an intitutionalising administration and society, and a changing farming identity – from wageworker to individual farmer. According to the EU rural transition is merely a "timelag". However, the idea of "path dependency" is taking over from the early very neo-liberal model of transition that expected a "shock therapy package" of price liberalization, stabilization and privatization to be able to dissolve the past in a decade (e.g. Lipton & Sachs, 1990). Today institutional and evolutionary economists argue for building "new" within the framework of the "old". It views shock therapy as the wrong medicine. Legacies are inherited from the socialist order and these are variously interpreted as "path dependency", "cultural persistence" or "circulation of elites" (e.g. Goldman, 1994). The concrete and the abstract In order to grasp the complexity of structures and change in the Baltic countryside the research design is one that repeatedly must move between concrete and abstract, and between particular empirical cases and theory. It is by such reasoning that we can attain a deeper insight into the reality. The same structures can produce different mechanisms and outcomes according to the context of past and present. The assumption that the Baltic countryside will follow the same development as the Western countries and that transition is a matter of time is too simplistic. In critical realism reality is stratified into the real, the actual, and the empirical (e.g. Bhaskar, 1978). Events in the actual strata arise from the working of mechanisms which derive from structures in the strata of the real. But there is more to the world than patterns of events. A crucial implication of this ontology is the possibility that powers may exist unexercised and what has happened does not exhaust what could happen. Another context might pose barriers to powers or generate other combinations of mechanisms of change. Structures and powers are not always activated or result in the same outcome as these take place within different geo-historical context (Danermark et al, 1997, Sayer, 1999). Sayer (1999) writes "social change is evolutionary – path-dependent yet contingent, shaped by legacies yet affected by contingently related processes or conditions" (Sayer p.16). What structures and powers do and might affect the Baltic countryside, under what circumstances they work and what the outcome is are the difficult questions. An intensive study of the problems, possibil


Sparse representation using trained dictionary is advantageous over the standard parametric bases. Recently, a dictionary training algorithm called SGK has been proposed as an alternative to the well known K-SVD algorithm. Analytically it has been shown that SGK has a superior execution speed in comparison to K-SVD, and it is advantageous to use SGK for constrained sparse coding. Through synthetic data experiments it has also been shown that the SGK dictionary training performances are comparable with K-SVD. However, these claims have not been verified for real data in practice. In this article, by training dictionaries on a face image database, we made a comparison between SGK and K-SVD using the problem of image recovery (inpainting and denoising). We have also introduced a simple technique to avoid incursion of noise into the dictionary.


Background: 1,25-dihydroxyvitamin D3 has been proven to be able to control the formation and biomineralization of tissue through a regulatory gene. A previous research even showed that a cell responsible for the formation of the enamel (ameloblasts), dentin (odontoblasts) and bone (osteoblasts, osteoclasts) was the target of  1,25-dihydroxivitamin D3. Purpose: This research was aimed to determine the role of 1,25- dihydroxyvitamin D3 in vivo in the development of teeth and alveolar bone tissue by analyzing MSX2 gene expression as a gene marker responsible for the growth and development of enamel, dentin, tooth root and alveolar bone. Methods: Samples used for RT-PCR analysis were total RNA of insisivus teeth and alveolar bone derived from mice. RT-PCR analysis was conducted by using primer-specific gene, MSX2. Primer gene, GAPDH, was also used as an internal control. Five hundred nanograms of total RNA were used as a template for PCR. Semi quantitative results of PCR were quantified by using ImageJ software. Results: RT-PCR analysis showed that the expression level of MSX2 was enhanced in the samples of teeth and alveolar bone treated with 1,25 dihydroxyvitamin D3. The increasing of MSX2 expression significantly occurred in alveolar bone samples. Conclusion: It can be concluded that 1,25 dihydroxyvitamin D3 could enhance MSX2 expression as a marker of the development of teeth and alveolar bone tissue. Therefore, 1,25-D3 dihydroxyvitamin is expected to be used as an agent to help the regeneration of teeth and bone tissue.

This paper proposes a model checking-based approach to verification of asynchronous consensus algorithms, an important class of distributed fault-tolerant algorithms. The proposed approach can be used to verify these algorithms against agreement, which is the key safety property of this class of algorithms. A consensus algorithm typically has runs of unbounded length and unbounded queues or sets of messages in transit, thus its state space is often infinite. This property makes application of model checking difficult, because model checking is based on state space exploration. Our approach can limit the use of model checking to a single round of an algorithm, by using a finite state model that over approximates the behavior of any single round. As a result, the problem of infinite state spaces can be circumvented. In case studies, two consensus algorithms are verified using this approach.


A pellet catalyst was prepared to be used in a large-scale steam methane reformer. Hydrotalcite powder (MG30) was used as a precursor to prepare MgAl2O4 pellet supports at different calcination temperatures. Ni-supported catalysts with egg-shell-type distribution were prepared on these pellet supports: Ni/sup-x (where x is the calcination temperature of the support with x = 1273, 1373, and 1473 K). Among them, Ni/sup-1473, which experienced the highest calcination temperature (1473 K), showed the highest methane conversion and lowest weight loss owing to carbon deposition. As a result, when the calcination temperature increased, the egg-shell thickness decreased, and the reducibility of the catalyst was enhanced. Although a small amount of Ni (3.5 wt%) was used, the egg-shell-type catalyst had superior catalytic activity and coke resistance. Therefore, the egg-shell-type catalyst using Ni as the active material and MgAl2O4 calcined at high temperature as the support is expected to be appropriate for large-scale industrial steam methane reforming reactions.


This paper introduces a recursive temporal algebra based on temporal semantics for querying time-varying data. The algebra, called /spl Rfr/*, is based on a temporal relational data model in which a temporal database is modeled as a collection of time-varying relations. Each time-varying relation is a collection of ordinary relations indexed by moments in time. In /spl Rfr/*, recursive queries (such as the transitive closure of a given relation) can be formulated through equations. It is shown that other forms of recursion, such as linear recursion, can also be expressed using iteration through time. Temporal completeness of /spl Rfr/* is established, with respect to two other temporal algebras based on temporal semantics which offer linear recursive operators.


While the paradox of plenty is given much weight on raging debates on resource endowment and growth path of the Southern Africa Development Community (SADC) countries. The study seeks to establish the effect of trade liberalisation on mining total factor productivity. The study employed panel data of selected seven countries from the SADC for the period 1990–2017. The countries in the sample include Botswana, South Africa, Tanzania, Namibia, Zimbabwe, the Democratic Republic of the Congo (DRC), and Zambia, and were chosen based on data availability. Hicks-Moorsteen productivity index was applied to generate the total factor productivity change. A panel auto regressive distributed lag model (PARDL) and pooled mean group (PMG) are the estimation techniques used. The inquiry is crucial to SADC because mining production is a source of foreign exchange that directly contributes to economic growth. However, with open economies of SADC study expects the easy flow and diffusion of technology to aid productivity in the mining sector (Griffith, Redding, & Van Reenen, 2014). Results indicate a positive and statistically significant long-run relationship between trade openness and total factor productivity change in the mining sector. The study recommends progressive trade openness in the mining sector, human capital development, research and development to augment technology transfer.


Abstract The cyclopropanation reaction of cyclohexenones with telluronium ylides was studied. The products were proved to be the derivatives of bicyclo[4, 1, 0]heptan-2-one.


The single factor experiment design was conducted with six crude protein levels,including 16%,18%,20%,22%,24% and 26%.The 480 quails were chosen and distributed into six groups randomly.There were four repetitions in each group and 20 quails in each repetition.The experiment was divided into two periods artificially which were 6 ~ 33 weeks(earlier stage) and 34 ~ 41 weeks(latter stage).The results showed that the egg production of group 1 in latter stage was lower than that of other groups significantly(P0.05),and laying rate was lower than group 2 and group 4 significantly(P0.05).There were no differences on the conversion of CP level within groups(P0.05).The egg shell strengthen of group 2 in earlier stage was lower than that of group 6 significantly(P0.05).The egg shell thickness of group 1,2 and 3 in earlier stage was higher than that of group 4 and group 6 significantly(P0.05).The egg shell thickness of group 1 and 2 in latter stage was higher than that of group 6 significantly(P0.05),while the egg shell thickness of group 1 in latter stage was higher than that of group 4 significantly(P0.05).The egg performance and the price difference between egg and diet of quails which feeding the diet with 18% CP level was the best,while the egg performance of quails was not improved by higher CP level,such as 20~26%.


This work aims to study the effect of semi-ellipsoid texture on the bearing load capacity and maximum oil film temperature of tilting pad journal bearings. It has been shown that surface texture can improve the steady-state performance of bearings, but there are few studies on tilting pad journal bearings. A thermal elastohydrodynamic model of tilting pad journal bearings have been developed to support the analysis and solved by the finite difference method. The calculation results of the model are in good agreement with the simulation results of MADYN 2000 software, which proves the validity of the model. The effects of texture distribution, depth, radius, and density on the characteristics of tilting pad journal bearings were studied and compared with those of untextured tilting pad journal bearings. The results show that texture can significantly enhance or weaken the steady-state characteristics of tilting pad journal bearings, which is related to the texture parameters. This work provides a reference for the design of tilting pad journal bearings.


1dG(v)+1 , where (G), V (G), and dG(v) are the independence number of G, the vertex set of G, and the degree of a vertex v in G, respectively. We discuss several improvements of this lower bound on independence. Algorithmic realizations are also considered.


Heavy Majorana neutrinos beyond the standard model can simultaneously explain the origin of tiny neutrino masses and matter-antimatter asymmetry in our Universe. The existence of heavy Majorana neutrinos will also lead to lepton number violation and confirm the possibility of rare lepton-number-violating W decays. With contributions from two different Majorana neutrinos, nonzero CP asymmetry may be generated from the rate difference between W decay and its CP-conjugate process. The aim of this study is to investigate the prospects of measuring CP violation in rare W decays via Majorana neutrinos at the LHC. Our calculations show that the induced CP asymmetry is independent of the Majorana neutrino mass for . Such a CP asymmetry, if observed, would in turn provide unambiguous evidence of new physics beyond the standard model.


RhI–NHC–olefin complexes bearing a N,O-quinolinolate bidentate ligand have been prepared from [Rh(μ-OH)(NHC)(η2-olefin)]2 precursors (olefin = cyclooctene, ethylene). The disposition of the chelate ligand with regard to the carbene in the square planar derivatives is strongly influenced by the steric hindrance exerted by the coordinated olefin. These complexes efficiently catalyzed the addition of thiophenol to phenylacetylene with good selectivity to α-vinyl sulfides, which can be increased up to 97% by addition of pyridine. Several key intermediates have been detected including the η1-alkenyl species resulting from alkyne insertion into a Rh–H bond. DFT calculations on the mechanism support a hydrometallation pathway that entails the oxidative addition of thiol, 2,1-insertion of the alkyne into the Rh–H bond, and reductive elimination as the rate-determining step. Remarkably, coordination of pyridine to the β-alkenyl intermediate but not to the α-alkenyl, which results in a net stabilization, is the key for the Markovnikov selectivity.


Abstract The rise of economic inequality is a major global problem, one that economists have an important role in explaining and addressing through policy. Despite increased availability of data, our theoretical understanding of the dynamics of inequality, its persistence, and policies to address this problem remain in their infancy. The new subfield of stratification economics focuses on intergroup inequality by race and gender and offers a useful lens through which to explore the complexity of interacting systems of inequality. This article evaluates three recently published books on inequality through that lens.


This article presents the design, analysis, and prototype test of a novel spatial deployable three-degree of freedom (DOF) compliant nano-positioner with a three-stage motion amplification mechanism (MAM). Inspired by deployable structures, a new design concept, namely monolithically spatial compliant mechanism (MSCM) is proposed to minimize the overall structure. Based on MSCM, a folding operation is employed uniquely by arranging three typical kinds of basic MAM modules with two sets of hooke joints. Due to the spatial structure, the dimensions in horizontal plane is reduced by 60.94%. Furthermore, the proposed nano-positioner demonstrates the simultaneous design of large-ratio amplification mechanism, compact, highly flexible, and assembly-free spatial XY platform with integrated Z platform. Analytical modeling is carried out, and finite element analysis is conducted to optimize the geometric parameters. A prototype is fabricated to verify the performances of the nano-positioner through tests. Experimental results demonstrate that the maximum displacements in <inline-formula><tex-math notation="LaTeX">$x$</tex-math></inline-formula>-, <inline-formula><tex-math notation="LaTeX">$y$</tex-math></inline-formula>-, and <inline-formula><tex-math notation="LaTeX">$z$</tex-math></inline-formula>-axes can reach 177.33, 179.30, and 17.45 <inline-formula><tex-math notation="LaTeX">$\mu$</tex-math></inline-formula>m, respectively. The motion amplification ratios in the <inline-formula><tex-math notation="LaTeX">$x$</tex-math></inline-formula>- and <inline-formula><tex-math notation="LaTeX">$y$</tex-math></inline-formula>-axes can reach 10.19 and 10.30, respectively. Moreover, by adopting proportional-integral-derivative feedback controller, the closed-loop control experiments are conducted. The results show that the motion resolution in three axes can all reach 5 nm. As the MSCM has been verified to be feasible and favorable, it can be anticipated that the design concept will contribute to the multiformity and development of compliant mechanisms.

The methyl CH‐stretching overtone spectra of gaseous monohydrogenated nitromethane NO2CHD2 have been recorded with conventional near infrared spectroscopy in the ΔvCH=1 to 4 regions and by intracavity laser photoacoustic spectroscopy in the ΔvCH=5 and 6 regions. They all exhibit a complex structure with, at ΔvCH=1 and 2, a characteristic asymmetric top vibration–rotation profile which vanishes as vibrational energy increases. These spectra have been analyzed with a theoretical model which takes into account in the adiabatic approximation the coupling between the anharmonic CH stretch described by a Morse potential and the quasifree internal rotation of the methyl group. All the parameters of this model (the zero point energy, the CH stretch frequency, the expansion coefficients of the dipole moment function) and their variation with the internal rotation coordinate have been determined from HF/6‐31G** ab initio calculations. This simple calculation, which contains no adjustable parameters, successfully de...

An Emerging Problem for Educational Planners in Zaire: Unemployment Among the Educated Causes and Tentative Solutions (August 1978) Radja S. bin Saidi, B.A., College of Wooster M • Ed . , Suffolk University, Ph.D., University of Massachusetts Directed by: Dr. Richard 0. Ulin This study is both a critique of the policies of educational reform put into effect in Zaire since independence as well as a definitive statement of how the objectives of social, political, and economic development as defined by Zaire's leaders can be implemented through a coherent national education policy. The Zairean pre-colonial philosophy of education, together with the Belgian colonial educational assumptions, objectives, and policies are discussed in order to put the present educational issues in Zaire in their proper historical and cultural context. In its conclusion, the study describes the importance of a political culture or national ideology as the proper foundation and template for the development of cultural, political, and economic objectives in the schools. The democratization of education, when it is not based on a solid Zairean ideology, is doomed to fail to meet the objectives of authentic national


Due to its abundant availability, eco-friendliness, and high sustainability, biomass-derived activated carbon has captured more attention in recent years. In this study, activated carbon was derived from Palmyra palm flowers (PPF) using a conventional chemical activation process and carbonization at different ambient temperatures, viz. 700, 800, and 900 °C. The carbonized PPF was chemically activated using 1 wt.% potassium hydroxide to increase the microporosity and specific surface. The experimental data were analyzed using an X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDX), Raman spectroscopy and Fourier transform infrared spectroscopy (FT-IR). The nitrogen adsorption/desorption isotherm curve for activated carbon synthesized at the activation temperature of 900 °C indicated type IV with a hysteresis loop associated with mesopores formation and a specific surface area of 950 m2g-1. The supercapacitor electrodes made with PPF-derived carbon were evaluated for their electrochemical performance by electrochemical impedance spectroscopy, cyclic voltammetry, and galvanostatic charge/discharge measurements. In the aqueous electrolyte (3 M KOH), electrochemical experiments showed that PPF-900 electrode has a specific capacitance of 155 F g-1 at 1 A g-1 and significant cyclic stability (97.3 % capacitance retention over 5000 cycles at 10 A g-1), while energy and power densities were estimated as 15.1 Wh kg-1 and 100.6 W kg-1. This study suggests that biowaste products could be transformed into activated carbon materials to improve the performance of energy storage materials, and it adheres to the 'waste to treasure' principle.


A 4-year study (2006-2009) with three irrigation regimes (A= control variant without irrigation, A2= 60–100 % Field Water Capacity (FWC), A3= 80– 100 % FWC), three levels of nitrogen fertilizer (B1= control variant without any nitrogen fertilizer, B2= 100 kg N ha-1, B3= 200 kg N ha-1), and four genotypes (C1 = OSSK596 ; C2 = OSSK617 ; C3 = OSSK602 ; C4 = OSSK552 ) with similar vegetation length (FAO 500 and FAO 600) were conducted on trial fields of Agricultural institute in Osijek. Vegetation seasons where quite different regarding weather conditions, mean air temperatures and precipitation quantity. Although all four years of research where unfavorable for maize production, years 2007 and 2009 where especially unfavorable because of the severe drought. Aim of the study was to evaluate influence of genotype, nitrogen fertilizer and available amount of water to maize yield and hectoliter weight as quality parameter. Irrigation treatment was significant for all four years of experiment with yield increasing for 13%, and for hectoliter mass in dry years 2007 and 2009 as well, but with the slightly decreasing. Nitrogen fertilizer increased maize yield (for 16%) and hectoliter mass as well. Maize yield (C1 = 9259 kg ha-1 ; C2 = 9814 kg ha-1) and hectoliter mass (C3 = 66.619 kg ; C4 = 72.453 kg) varied thru tested genotypes.


Hypoplastic left heart syndrome is a form of congenital heart disease that is associated with significant lifelong morbidity and mortality. Although rarely reported together, the prognosis for patients with hypoplastic left heart syndrome and congenital anomalies of the airway or lung, such as congenital diaphragmatic hernia, has been shown to be very poor. The outcomes for patients with hypoplastic left heart syndrome and congenital lobar emphysema specifically is currently unknown. Reported herein is the first case of a child with a rare combination of hypoplastic left heart syndrome and congenital lobar emphysema, and a discussion of his presentation, diagnosis, management and outcome to date.


Burgers are one of the processed meat products currently being traded in Indonesia to the suburbs and even to the villages. The raw materials for burgers are beef, chicken, fish, and pork. Until now, the price of beef is still costly for many customers. However, it turns out that many burger producers sell their products at very low prices. This condition raises suspicion from consumers that the producers mix or replace the beef with pork. Based on this issue, this study aims to examine the content of pork (porcine DNA) in burger products sold in traditional markets in Jakarta and frozen food outlets in the villages around Jakarta. Pig DNA testing used the Real-Time Polymerase Chain Reaction (RT-PCR) method. The results showed that porcine DNA was not detected in all the test samples (10 samples) from different brands, including those with the MUI halal logo.
