Having served for many years as senior reviewers and/or consultants on many complex embedded systems, we have witnessed that in many cases major difficulties have often been caused by a relatively small number of complex and difficult hardware and especially software problems. In many cases however, solutions to these problems are known, but only by a relatively small number of experts. This leads to the recurrent phenomenon of many projects encountering serious troubles and subsequently being rescued by "tiger teams".


Multicriteria decision analysis is applied to ecosystem management planning in a forest landscape. Ten alternative action plans were evaluated employing five criteria. For some criteria, cardinal measures with their associated uncertainties were obtained. For other criteria, only ordinal (ranking) information was available. The Stochastic Multicriteria Acceptability Analysis with Ordinal criteria (SMAA-O) method was used, as it accommodates both cardinal and ordinal data. This is the first application of SMAA methods to forest management. SMAA-O represents inaccurate or uncertain cardinal criteria measurements by a joint probability distribution. Ordinal data is converted into stochastic cardinal data by simulating mappings between ordinal and cardinal scales that preserve the given rankings. At the same time, the unknown or partly known preferences of the decision maker are simulated by choosing weights randomly from appropriate distributions. The main results of the analysis are acceptability indices that describe the variety of different weights that support an alternative for a given rank. The special characteristics of SMAA-O are best utilized in problems involving uncertainty and where both cardinal and ordinal data are to be employed. It also serves well as an analysis tool in interactive planning processes, especially when criteria weights are not known or they are difficult to assess.


The objective of this research was to determine the relationship between the organizational culture and the quality of service at the "Patty" seafood restaurant in the city of Trujillo - 2019.The population was made up of 350 clients, of which, using simple random probabilistic sampling, a sample of 184 clients attended the "Patty" seafood restaurant in the city of Trujillo. The research was descriptive, with a cross-sectional correlational design, using the survey technique and the questionnaire instrument for data collection. The procedures provided by the statistics were also used, starting with the construction of tables, the construction of graphs and the application of the hypothesis test to test the research hypothesis. As a result, it was obtained that 79.3% of the respondents indicate that the organizational culture is good and in the quality of service 50.5% of them indicate that it is good. It has also been found that there is a significant positive relationship between organizational culture and quality of service (p <0.05).It was concluded that there is a significant positive relationship between the organizational culture and the quality of service at the "Patty" seafood restaurant in the city of Trujillo - 2019. It is recommended to permanently evaluate and improve the organizational culture and quality of service variables, gathering the opinion of the clients and training the staff.


ABSTRACT: Myxoma is a common cardiac non-malignant tumour arising mostly from the leftatrium (75%), right atrium (10%) and the rest equally between right and leftventricles. Myxoma in the left ventricle is a very rare phenomenon. We describethe case of a 50yrs old patient who had left ventricular Myxoma presenting asstroke and subsequently resected successfully. The patient also underwent aCABG in the same setting. LV myxoma with coronary artery disease andpresenting as stroke has not been described in medical literature to the best of ourknowledge.


In this work, we study the effect of surface stress on the stability behavior of a circular ring with nano dimensions under uniform pressure. It is known that the surface elasticity and residual surface tension can have significant effects on the mechanical behavior of the nano-sized structures. Taking both effects into account, we present an analytical expression for the smallest critical radial load acting on the nanoring. It is shown that, depending on surface mechanical properties of the nanoring, these effects can stabilize or destabilize the nanoring under uniform pressure. The results, in this work, are expected to provide informative predictions on characterizing the stability behavior of nano elements used in nanostructured devices.


ABSTRACT Recent research argues that external threats like war spur EU polity formation (Kelemen & McNamara, 2022). One key mechanism of this process is public support for policy responses designed by policymakers. However, like the 'rally-round-the-flag' effect (Mueller, 1970), public support wanes over time and we decompose this decrease into two elements: salience and polarisation at the domestic level for national and European policies in both soft and hard security (aid and sanctions). We show that while salience can sustain public support for European policy innovations, polarisation about national and (unexpectedly) European policies accelerates its decline. We thus qualify the story of EU polity formation through external security crises.

unique aspect of this third issue of IEEE Pervasive Computing is that it is a joint special issue with IEEE Wireless Communications. The two magazines used a single call for papers, a single submission process, and a combined reviewing process. Authors submitted material to the joint issue rather than to a specific magazine, and only in the final stage of the reviewing process did we assign articles to one magazine or the other. I would like to thank Mahmoud Naghshineh, editor in chief of Wireless Communications, for his support and cooperation in creating this issue. Lancaster University put together this collection of articles on context-aware computing. Context awareness refers to the properties of a system that make it aware of its user's state and surroundings and help it adapt its behavior accordingly. This topic is central to pervasive computing because a system that strives to be minimally intrusive must be context-aware. A user's context can be quite rich, consisting of attributes such as physical location, physiological state (for example, body temperature and heart rate), emotional state, personal history, daily behavioral patterns, and so on. If a human assistant were given such context, he or she would make decisions in a proactive fashion, anticipating user needs. In making these decisions, the assistant would typically not disturb the user at inopportune moments except for an emergency. Can a pervasive computing system emulate such a human assistant? A key challenge is obtaining the information needed to function in a context-aware manner. In some cases, the desired information might already be part of a user's personal computing space. For example, that space might include schedules , personal calendars, address books, contact lists, and to-do lists. Systems must sense more dynamic information in real time from the user's environ-ment—such as position, orientation, people's identities, locally observable objects and actions, and emotional and physiological states. Implementing a context-aware system requires addressing many issues: • How does the system represent context internally? How do we combine this information with the system and application state? Where should the system store context—locally, on the network, or both? What are the relevant data structures and algorithms? • How frequently does the system need to consult contextual information? What is the overhead of considering context? What techniques can we use to keep this overhead low? • What are the minimal services that an environment must provide to make context awareness feasible? …


: "The Guidelines for Construction of Ideological and Political Courses in Colleges and Universities" promulgated by Ministry of Education requires the specialized course and the ideological and political course go hand in hand, and constructs a long-term mechanism of moral education. As far as the experiment-based chemistry discipline is concerned, it is also urgent to change the experimental teaching ideas, and strive to cultivate all-round talents with high theoretical level and strong scientific research literacy to meet the needs of the new era. In this paper, the comprehensive chemical experiment based on BiVO 4 nanofiber preparation and electrochemical performance characterization was selected as a carrier. A new type of comprehensive experimental teaching mode of bidirectional transmission of knowledge between teachers and students was constructed by the integration of the ideological and political elements. The way of scientific research infiltration extends the content of comprehensive chemical experiment to the frontier of scientific researching fields, increases the breadth and novelty of lab teaching content, stimulates students' enthusiasm for scientific research, enhances students' passion for basic research, and consolidates the foundation of building a powerful country strong in science and technology. The analysis of typical examples of dissecting sparrows refine the moral elements contained in comprehensive chemical experiments, realize the seamless connection between professional teaching and moral education, further cultivate students' speculative spirit of exploration and innovation, as well as increase their sense of social responsibility and realize all-round education.

In this work, a variety of semiconducting oxides were prepared and principally characterized by means of spectroscopic techniques (absorbance FT-IR, diffuse reflectance UV-Vis-NIR) to shed light on the electronic properties and defects involved at the roots of gas sensing capabilities. The thick films were obtained by screen printing technology on which electrical characterization and gas sensing measurements were performed. From the cross analysis of the results, a description of the specific sensing mechanism for each material is proposed.


The antitrust laws are increasingly used to prosecute alleged acts of market manipulation, particularly against firms in the banking and energy industries. Both industries are now regulated subject to fraud-based market manipulation rules, but antitrust remains a vehicle on which private claims are based. If anti-manipulation enforcement wanes (or its legal foundation is eroded) with political change, private antitrust actions might fill the void — if such claims are substitutable. As economists practicing in these fields, we address in this paper whether manipulation claims brought under the antitrust laws are substitutable for those actionable under the manipulation rules.

Groundwater resource depletion, resulted from agricultural, industrial and domestic usages, is an issue of increasing water resource concern. Many parts of USA, especially in Mississippi Delta, are now experiencing an overdraft of groundwater resources. Afforestation has been applied to sustain water quantity, improve water quality, and mitigate river flooding. However, knowledge of afforestation's impacts on groundwater resource availability is currently fragmented. In this study, we applied the USGS's MERAS (Mississippi Embayment Regional Aquifer Study) model in conjunction with ModelMuse to estimate the impacts of afforestation on groundwater resource availability at the Upper Yazoo River Watershed (UYRW) in Mississippi. This watershed consists of 49% crop land and 46% forest land. Two simulation scenarios were developed in this study. The first scenario was a base scenario for the agricultural pumping conditions commonly used as well as for the natural forest conditions normally existed in the UYRW. The second scenario was the same as the first scenario except that the crop lands were converted to the forest lands as a result of afforestation. During the afforestation, all of the agricultural pumping wells have been "removed" because no groundwater irrigation is needed for tree growth in this humid subtropical region. Simulations showed that the average groundwater level at the UYRW had declined 1.2 m without afforestation over a 20-year period from 1987 to 2007, whereas the average groundwater level at the UYRW had declined only 0.13 m with afforestation for the same simulation period. The latter occurred due to the "removal" of agricultural pumping wells. Results suggested that afforestation had mitigated the groundwater resource depletion at the UYRW. This approach (afforestation) could be applied to marginal (low productivity) crop lands for groundwater conservation.

Objective: Diabetic retinopathy is a vision threatening disease one of the worst complications of diabetes. The aim of our study is to compare the clinical outcomes and ultrastructural changes in diabetic retinopathy patients after intravitreal ad- mission of either Ranibizumab (Lucentis) or Aflibercept (EYLEA). Methods: In our prospective study 39 patients with prolifer- ative diabetic retinopathy (PDR) were enrolled. They were divided in two groups – patients treated with Ranibizumab – 11 and EYLEA treated patients with PDR – 28. In both groups complete ophthalmologic examination including OCT was performed. In 6 patients (3 from each group) pars plana vitrectomy with excision of epiretinal membranes has been done. Transmission and scanning electron microscopy of the membranes has been performed. Results: Clinically in both groups decrease of the neovascular proliferations and macular oedema were found. Central retinal thickness (CRT) was reduced with approximately 100-120 mc. In both groups general shrinking of the neovascular proliferations with lower risk of bleeding in PDR patients has been observed. The ultra structural analysis showed more significant reduction of endothelial fenestration after EYLEA application with clustering of thrombocytes and erythrocytes in the capillary lumen. Conclusion: Our results point out that both Aflibercept as well as Ranibizumab is very effective in treating PDR. Eylea inflicts more significant reduction of endothelial fenestration and more evident thrombotic microangiopathy than other anti-VEGF drugs. Both drugs have similar action in mild to moderate PD and have very good action in combination with PPV in terms of intraocular bleeding and long term results.


The present study describes development and subsequent validation of stability indicating HPLC and HPTLC methods for simultaneous estimation of Telmisartan (TLM) and Atorvastatin (ATV) in their combined formulation. The proposed RP-HPLC method utilizes a Phenomenex Luna C 18 column using acetonitrile: 0.025 M ammonium acetate (38 : 52%, v/v) as mobile phase (pH 3.8), flow rate of 1.0 mL/min. Quantification was achieved with UV detection at 281 nm over concentration range of 12 to 72  μg/mL for TLM and 3 to 18  μg/mL for ATV respectively. In HPTLC, separations were performed on silica gel 60 F 254 using toluene-methanol-ethyl acetate-acetic acid (5 : 1 : 1 : 0.3, v/v) as mobile phase.

UV Spectrophotometric method was developed and validated for the quantitative determination of Ozagrel in bulk drug and in pharmaceutical formulations. Ozagrel shows the maximum absorbance at 270 nm. Ozagrel follows Beer's law in the concentration range of 1.0-10.0 µg/ml (r = 0.999). The detection limit (DL) and quantitation limit (QL) were 0.4629 and 1.4027 µg/ml respectively. Accuracy and precision were found to be satisfactory. The developed methods were validated according to ICH guidelines. All the validation parameters were found to be satisfactory accordance with the standard values. Therefore, the proposed method can be used for routine practice for the determination of Ozagrel in assay of bulk drug and pharmaceutical formulations.

A large quantity of molecular information on heart development, function, and disease has been generated over recent decades. However, most recent studies have been dominated by reductionistic approaches, and thus many aspects remain unclear, particularly regarding the primary causes of complex cardiovascular diseases such as congenital heart malformations. With the advent of high-throughput technologies, systems-based approaches have developed rapidly in biology and medicine. In the biology of cardiovascular systems complex data within or across different molecular levels of biological systems or pathways can be integrated and combined to identify the causes underlying cardiac diseases, which might not be possible otherwise. This is in agreement with data suggesting that biological molecules in individual regulatory layers, such as transcripts, proteins, and metabolites, act within networksrather than independently of each other. Thus systems biology provides a promising approach to fully addressing the complexities of congenital heart disease.


We consider the problem of optimal recovery of an unknown function $u$ in a Hilbert space $V$ from measurements of the form $\ell_j(u)$, $j=1,\ldots,m$, where the $\ell_j$ are known linear functionals on $V$. We are motivated by the setting where $u$ is a solution to a PDE with some unknown parameters, therefore lying on a certain manifold contained in $V$. Following the approach adopted in [Maday, Patera, Penn and Yano, Int. J. Numer. Methods Engrg., 102 (2015), pp. 933--965, Binev, Cohen, Dahmen, DeVore, Petrova, and Wojtaszczyk, SIAM J. Uncertainty Quantification, 5 (2017), pp. 1--29], the prior on the unknown function can be described in terms of its approximability by finite-dimensional reduced model spaces $(V_n)_{n\geq 1}$ where $\dim(V_n)=n$. Examples of such spaces include classical approximation spaces, e.g., finite elements or trigonometric polynomials, as well as reduced basis spaces which are designed to match the solution manifold more closely. The error bounds for optimal recovery under suc...


Microtine rodents provide an excellent model for the study of the neurobiology of social bonds. In this review, we discuss how the presence of a microsatellite sequence in the prairie vole vasopressin receptor gene may determine vasopressin receptor binding patterns in the brain and how these patterns may in turn affect social behavior.


Electrolyte concentration is one of the important parameters on Lead-Acid Battery (LAB) outcome. Lead-acid battery has been made with static and dynamic electrolyte treatment where 4 variations of electrolyte concentration (20%, 30%, 40% and 50%) and 1A current applied in the system during charging-discharging test to analyze the relationship of the electrolyte concentration to the battery characteristic and compare static and dynamic lead-acid battery performance. The experiment result that for dynamic lead acid battery, the capacity increases along with the higher concentration from 20% to 40% but decrease at 50% compare to 40% for 3 first cycle charge-discharge test when the static lead-acid battery unwork at concentration 20% and show the increases capacity along with increases concentration. In capacity and efficiency point of view, dynamic lead-acid show better performance compare to static lead-acid battery.


In a search for sources of bias in sex attribution, 88 subjects with liberal and conservative attitudes toward women were compared as to performance on the Sex Attribution Questionnaire. Among women, conservative judges made more inappropriate sex attributions than liberal judges. Liberal judges erred in another way by failing to make sex attributions when they were appropriate. Among men, attitudes toward women had relatively little effect on sex attributions. For all judges, female "speakers" rather than males were more commonly the victims of such biases. Discussion focused on the differential importance of attitudes toward women as a factor in the perception of men and women.


Theinfluence of the size of Haplic Luvisol and Mollic Gleysol aggregates on soil water potential-moisture charac- teristics, saturated water conductivity, diffusivity and evaporation at different external conditions are presented. It has been found that size of aggregates strongly influenced hydrophysical characte- ristics and evaporation of investigated soils. The size of Haplic Luvisol and Mollic Gleysol aggregates had an impact on signifi- cant differentiation of the water bounded with the potential less than 10 kJ m -3 (pF 2). The saturated water conductivity increases significantly with the increase of aggregate size. The diffusivity coefficients of all the investigated aggregate fractions increased with the increase of moisture and they were higher for Mollic Gleysol aggregates than for Haplic Luvisol ones. The increase of evaporation under steady-state conditions was determined by the soil aggregation, i.e., the evaporation was always higher for fine- and medium-aggregated soil samples than for coarse-aggregated ones. This increase was very high and for the investigated soils it reached eleven times (Mollic Gleysol, Ep=4.5 mm day -1 ).

Purpose
Friction pairs of the hydro-viscous drive speed regulating start device should be designed based on the rated torque. To obtain design basis of the rated torque of the hydro-viscous drive speed regulating start device, studies on effect of torque ratio (a ratio of the load torque to the rated torque) on speed regulating start were carried out theoretically and experimentally.

Design/methodology/approach
Under different torque ratio, the modified Reynolds, the thermal energy and the viscosity-temperature equations were solved simultaneously by using finite element method to reveal variation laws of the oil film load capacity and torque transmission during the starting process. Then, speed regulating start experiments were carried out to study the following performance of the output speed.

Findings
The results show that oil film thickness decreases with the increase of the torque ratio; when oil film thickness is less than 0.05 mm, oil film temperature increases rapidly with the decrease of oil film thickness, which eventually deteriorates performance of the speed regulating start; when the torque ratio decreases to about 0.3, output speed shows a better following performance.

Originality/value
It indicates that, to acquire a better speed regulating start, the rated torque of the hydro-viscous drive speed regulating start device should not be less than three times of the load torque. Achievements of this work provide theoretical basis for optimal design of the friction pairs of the hydro-viscous drive speed regulating start device.


The use of agricultural by-products have been widely investigated as a replacement for current conventional methods for removing heavy metals from waste water, such as chemical precipitation, ion exchange, membrane technologies and electrochemical treatment. Although adsorption process using activated carbon are successfully applied for purification of potable water and the removal of organic pollutants in waste water, the expensive cost of the adsorbent material is still an issue for developing countries. Alternative adsorbents using low cost agricultural by-products are now becoming emergent. The application of low cost adsorbent for treating various adsorbate contaminants such as colour, trace metals, trace organics or chemical oxygen demand have been investigated worldwide. A focus on heavy metals contamination in waste water is a major concern due to their potential toxicity, persistence and tendency to become concentrated in food chains. With sources from more than 100 published papers low cost agricultural by-products have demonstrated outstanding capabilities in adsorbing heavy metal ions from aqueous solution. In this review, an extensive list of adsorbent literature has been compiled to provide a summary of information on a wide range of low-cost agricultural by-product adsorbents. The adsorption capacities depend largely on the characteristics of the adsorbent, pretreatment of the adsorbents, pH and the initial metal concentration.


Laryngeal papilloma is the most common benign tumor of the larynx and is caused by the human papilloma virus. It is often difficult to treat papilloma because it recurs or disseminates frequently. Micro laryngeal surgery is usually employed under general anesthesia, however some patients need to have the surgery repeatedly. That can be physically and mentally demanding and can lead to complications associated with general anesthesia or direct laryngoscopy. In addition, some patients have difficulty undergoing general anesthesia. We reported on 4 adult cases with laryngeal papilloma treated by surgery with a Nd-YAG laser under local anesthesia. One case had multiple and expanded papillomatosis. General anesthesia was difficult in this case because of a cervical problem due to a previous traffic accident. He underwent surgery using the Nd-YAG laser twice. The lesion has not recurred for more than 1 year. Other cases also underwent surgery with the Nd-YAG laser several times, and their lesions had not recurred for over a year. The Nd-YAG laser can be effective on exophytic laryngeal papillomas which recur because of their high tissue permeability. Operation under local anesthesia is less invasive procedure. We believe that endoscopic surgery with the Nd-YAG laser under local anesthesia plays a supplementary role in the treatment of laryngeal papilloma. It is most prudent to observe the lesions in detail and at a minimum to perform a biopsy under a microscope during the first operation.


Wire bonding is one of the key processes which connects the wafer die and the lead frame in the IC packaging process. It is noted that process parameters influence both the speed and quality of bonding. Parameters, such as descending speed and cycles affect the bonding speed; while parameters such as bonding force and ultrasonic energy level affect the strength of joint. Both situations will affect the output (unit per hour, UPH), and lead to the variation of the production capacity as well.Nowadays, most companies in Taiwan still follow the rule of thumb when setting the process parameters. However, the large number of parameters in the bonding process makes it difficult for engineers to find appropriate parameters at once efficiently based on their experience only. When new products are introduced into mass production, engineers must go through multiple adjustments in a repeated trial and error way to find out the appropriate parameters, which takes lots of time, manpower and material resources.Using data mining techniques to establish predictive models for process parameters can not only increase the production capacity but also reduce the cost of the operation during adjustments. However, most studies in the field of wire bonding parameter optimization focused on increasing the bonding quality, while little consider the operation time and quality simultaneously. In this study, a data mining framework is proposed to extract the relationship between the bonding speed, bonding quality and the parameters.This study aims to increase production capacity by enhancing the bonding quality and the bonding speed simultaneously via recommending optimized process parameters. The proposed framework is based on a defect classification model constructed by random forest (RF) and extreme gradient boosting (XGBoost) method, and a multi-objective process parameters optimization model applying particle swarm optimization (PSO) method.An empirical study was conducted in a leading IC packaging and assembly company in Taiwan. The empirical result on 2 testing products reveals that the proposed approach increases the bonding quality by 70%, whereas the bonding speed is enhanced by 20%; overall, the proposed approach benefits output UPH by 26.6%, 5.0% for each product. Besides improving the production capacity, the proposed framework can also recommend parameters systematically and more quickly to enhance engineers' parameter tuning efficiency on-line and achieve the goal of reducing the introduction time of new products.


This work evaluates interference mitigation mechanisms to enable the operation of self-organizing hybrid terrestrial-satellite networks with aggressive frequency reuse between terrestrial and also satellite links. The objective is to take advantage of the improved capacity and resilience to congestion of such networks while assuring and efficient use of the spectrum. In particular, single- and multi-user hybrid analog-digital beamforming (HADB) techniques are considered as well as hybrid carrier allocation. The simulation results show network spectral efficiency improvements, with respect to conventional terrestrial backhaul systems, up to 2× when applying carrier allocation, and between 3.5× to 9× applying HADB in different environments.


The aim of the study was to apply statistical optimization technique for the development of ketoprofen loaded
mucoadhesive multiparticles to target the small intestine. The mucoadhesive multiparticles were prepared by
quassi- emulsion solvent diffusion method and filled in enteric coated capsules. All the formulations were
characterized for particle size, mucoadhesion, drug loading, entrapment efficiency, in vitro release studies. A 32
factorial design was used to optimization. The dependable variables were PVA concentration (X1) and rotational
speed of stirring elements(X2). The chosen response variables were particle size (Y1), percentage of drug release
for 24 h (Y2), mucoadhesion (Y3) and entrapment efficiency (Y4). The optimized formulation according to the study
was mucoadhesive microspheres prepared with 0.5% w/v of PVA and 400 rpm of stirring speed i.e ( -1, +1). The

We report on observation of photoluminescence in 1.2–1.4 eV spectral range from As‐doped GaN layers grown by plasma‐assisted molecular beam epitaxy. We attribute this emission to recombination in GaAs inclusions formed during the growth process in the GaN(As) layers. This near‐infrared emission is efficient under UV photoexcitation, but its intensity is low for excitation energies below the band gap of GaN. Low‐temperature photoluminescence spectra reveal a set of sharp emission lines with maxima from 1.516 eV to 1.436 eV. We attribute some of these sharp lines to the emission of excitons bound to nitrogen incorporated into the GaAs crystallites and also to their GaAs‐like optical phonon replicas. Photoluminescence excitation spectra show a series of maxima, which can be attributed to the formation of bound and free excitons and also to the formation of excitons with the simultaneous emission of GaAs‐like optical phonons.


The use of fire extinguishing software is based on the principles of system analysis, when any software is created for specific tasks or adapted to use on existing equipment samples. Therewith, a considerable part of the software cannot be implemented in conditions when the operation of technical means is autonomous or specialised. This includes devices of increased accuracy with the requirement to receive a response with a minimum delay. The originality of the study is conditioned by the fact that the principles of creating software for situations with minimal response require its consolidation with equipment that works on the principles of microcode. Based on the analysis of the current state of analogue-to-digital and functional conversion methods, it is shown that a promising area of research and improvement is the creation of converters on switched capacitors that combine the functions of ATFC, and also have an increased number of input values with high accuracy and speed. The methodological basis for creating new methods for constructing ATFC is a combination of structural and algorithmic principles for improving the accuracy of analogue-to-digital conversion based on the properties of capacitor cells. The practical significance of the study is determined by the possibilities of using hardware microcode as modules for the main software set.


Objective To establish and assess experimental rat model of metabolic syndrome(MS).Methods SD rats were randomly divided into 3groups:induced with normal-salt plus High-glucose-fat dietgroup(NS),induced with high-glucose-fat-salt diet group(HS)and the normal control group(NC).The rats in NS group were fed with nomal salt plus high sucrose-fat diet for totally 12weeks;the rats in HS group were fed with high sucrose-fat-salty diet for totally 12weeks;the rats in NC group were fed with normal diet.Blood of all rats were collected after fasting to measure fasting blood glucose(FBG),TG and HDLC.After 10weeks'feeding,the rats in two model groups which waistline achieves the standard were injected STZ.Results After nomal salt plus high sucrose-fat-high diet or high sucrose-fat-salty diet feeding and injected STZ in rats in NS and HS groups,weight,waistline,FBG and fasting blood fat of rats of these two groups showed significant differences in comparison with those of NC group(P0.05).At the end of 12weeks,there were statistical defference in levels of FBG,TG and HDL-C between NS group and HS group(P0.05).The model success rate of rats in HS group and in NS group is 66.7%and 40.0% correspondingly,There were statistical difference in two group(P 0.05).Conclusion Stable experimental MS Rat model can be established by high sucrose-fat-salty diet or high sucrose-fat diet in combination with single low dosage of STZ injection in a short time.There were statistical difference in model success rate between HS group and NS group.


Abstract
Inequalities in education have existed since the beginning of formal education. Educational disparities often emerge as you compare groups of students based on race, ethnicity, socioeconomic class, gender, and geography. This chapter seeks to stress the important role that early childhood experiences, including specific structures and processes during these foundational years play in potentially preventing the educational gaps of Black students. This requires intentional shifting from solely focusing on educational gaps to one that focuses on specific practices and policies that must be implemented to ensure that Black children are afforded the opportunities to meet their potential.


Objective To explore an atomic relationship between normal eustachian tube and that of otitis media,through multi-plane reformation of the multi-slice helical CT(MSCT),and provide anatomic basis for clinical application.Methods The Otitis media group consisted of 85 ears of 61 patients with otitis media.The control group consisted of 30 ears of 15 volunteers without symptoms of otitis media or abnormal findings in ET function tests.Both groups were scanned under MSCT,and then imaging data were reconstructed adopting multi-plane reformation.The bony part distance,the opening tubal distance,the closing tubal distance and the utility closing tubal distance were measured and compared in both groups.Results For control and otitis media groups,the diameters of pre-tympanic segment,of junctional portion of cartilaginous and bony,and the length of bony portion were(9.95±1.29) mm and(9.85±0.83) mm,(3.89±0.50)mm and(3.92±0.37) mm,(20.89±1.81) mm and(20.51±2.13) mm respectively.For static CT images,the length of open zone and occlusive zone were(10.99±0.87) mm and(8.50±0.55) mm,(36.90±6.73) mm and(42.26±7.19) mm respectively,however,the length of occlusive zone were(10.20±3.96) mm and(33.32±9.44) mm respectively for dynamic CT images.Conclusions There are no significant differences of the length of bony portion between otitis media and the control groups.The occlusive zone is longer in otitis media group than that in control group(P0.05) under the static CT,however,which is significantly longer in otitis media group than that in control under the dynamic CT.


In order to place limits on dark matter (DM) properties using γ-ray observations, previous analysis have often assumed a very simple parameterisation of the γ-ray annihilation yield; typically, it has been assumed that annihilation proceeds through a single channel only. In realistic DM models, annihilation may occur into many different final states, making this quite a rough ansatz. With additional processes like virtual internal bremsstrahlung and final state radiation, this ansatz becomes even more incorrect, and the need for scans of explicit model parameter spaces becomes clear. Here we present two different scans of the parameter space of the Constrained Minimal Supersymmetric Standard Model (CMSSM), considering γ-ray spectra from the Galactic Centre region and the Sagittarius dwarf galaxy, as obtained with the High-Energy Stereoscopic System (H.E.S.S.); one random scan and one likelihood scan combining the H.E.S.S. likelihood with other experimental results. The Galactic Centre search is complicated by a strong (unknown) γ-ray source, and we see no effect on the CMSSM parameter space when assuming a realistic DM density profile. In contrast, we show that observations of the Sagittarius dwarf galaxy disfavour the coannihilation region of the CMSSM and models with large annihilation cross-sections. This is true even under reasonable assumptions about the DM density profile, and constitutes the strongest constraint to date on coannihilation models within the CMSSM.


Introduction Management in breast cancer is heading toward less invasive approaches with high survival and low recurrence rates. Axillary lymph node dissection (ALND) has a high morbidity on breast cancer patients; on the other hand, sentinel lymph node biopsy (SLNB) overcomes such morbidity with comparable survival and recurrence rates. In this study, the authors aim to assess diagnostic accuracy of carbon nanoparticles (CN) in SLNB in patients with early breast cancer. Patients and methods From November 2020 to March 2022, patients with early breast cancer and clinically and radiologically free axillary lymph nodes who had SLN detection using CNs followed by ALND were included. Patients who received neoadjuvant chemotherapy, are pregnant, or refused consent were excluded. Results In this study, 30 patients with clinically node-negative early breast cancer patients were investigated using CN for SLN mapping. Mean age of our participants was 49.2±5.8. CN technique had a sensitivity of 100% (95% confidence interval: 80.49–100), specificity of 92.3% (95% confidence interval: 63.9–99.8), positive predictive value of 94.4%, negative predictive value of 100%, and false-negative rate=0%. The summary receiver-operating characteristics of CN showed excellent diagnostic performance with area under the curve of 0.962 (P=0.0001). Conclusion SLN mapping using proper technique is vital to avoid recurrence and promote survival and decrease morbidity without need for ALND. CN had excellent sensitivity and specificity with low false-negative rate.

Considerable attention has been directed toward documenting the effects of environmental chemicals on the endocrine systems of vertebrates, especially on development and reproduction. Given the well-documented role of hormones in controlling behavior, one would expect to see abnormal behavior in contaminated wildlife. We describe abnormal nest- building behavior in Tree Swallows (Tachycineta bicolor) breeding along the Hudson River of New York in areas highly contaminated with polychlorinated biphenyls (a group of chemi- cals known to disrupt endocrine systems). Previous studies of Tree Swallows have shown that nest quality is an important component of reproductive success. Swallows breeding in contaminated areas built smaller nests of lower quality compared with those in uncontam- inated areas. Our observations are consistent with the possibility that chemical contaminants interfered with behavior. Received 31 October 1997, accepted 11 May 1998.


The Tag map is constructed by TagSLAM framework and the camera track is located, meanwhile, the trajectory of the robot is calculated by integrating the obtained wheel tachometer data. The internal and external parameters of the camera and wheel tachometer are obtained by solving the least square problem after the camera and wheel tachometer tracks are aligned. This method can calibrate the internal and external parameters of camera wheel tachometer without the robot moving along a specific trajectory. Experimental results show that the method is accurate and the calibration results are very close to the standard values of internal and external parameters of camera wheel speedometer.

The results of this study are the need for training to improve market access, legality aspects and competitive advantage


adequate alternative, "ethnicity." On the one hand, Sangmpam prefers "tribe" due to its ability to capture and describe the pre-colonial peculiarities of Sub-Saharan Africa yet, on the other hand, is weary of the concept being jettisoned for the derogatory connotations of the (post-)colonial era. While he does not resolve the dilemma of conceptual use in this work, he offers an authoritative understanding on the subject of "tribe," "ethnicity," and the link between the two in SSA, and their links to colonialism. This monograph is worth close reading for anyone interested in accessing the starting point for overcoming the aforementioned dilemma; as such, the title of the book suggests Sangmpam might have opened up old wounds, but he certainly missed an opportunity to properly heal them.


Background: Determination of local bone mineral density (BMD) with cortical thickness and bone height may offer a comprehensive description of the bone the surgeon will encounter when he or she actually sets the implant. Quantitative computed tomography (CT) (i.e., quantitative interpretation of values derived from Hounsfield units with a suitable calibration procedure) is the modality of choice to determine BMD. The aim of the present clinical study is to determine the local bone density in dental implant recipient sites using computerized tomography.
Material and method: The sample consisted of (72) Iraqi patients whom referred to Al-Kharkh General hospital, Spiral CT scan Department for bone quality and quantity assessment after one week of dental implants insertion, the average of bone density was measured for 120 areas indifferent sectors of maxilla and mandible in Hounsfield unite.
Results: As a mean, males show higher bone density than females, decreased with increased age significantly, mandible show significantly higher bone density than maxilla. Maxilla revealed no significant difference between the three sectors, while in the mandible there was significant difference between posterior sector (613.1HU)and both anterior (821.3 HU) and premolar sectors (779.6 HU) with no significant difference between anterior and premolar sectors.
Conclusion: CT-Scan may provide a valuable aid to predict bone quality at potential implant sites and could be used to assess the change of bone density around dental implants.


The prediction of RNA structure with pseudoknots is an NP-hard problem. According to minimum free energy models and computational methods, we investigate the RNA pseudoknotted structure. The paper presents an efficient algorithm for predicting RNA structure with pseudoknots, and the algorithm takes O(n3) time and O(n2) space. The experimental tests in Rfam10.1 and PseudoBase indicate that the algorithm is more effective and precise, and the algorithm can predict arbitrary pseudoknots. We also present several types of pseudoknots considered in RNA folding structure, and analysis possible transitions between types of pseudoknots.


All surgical instruments used in brain biopsy operations for non-focal lesions should be quarantined—set aside in secure storage—until a definitive diagnosis has been obtained, the Department of Health recommended last week. The recommendation follows an inquiry into an incident at an English hospital that potentially exposed patients having surgery to Creutzfeldt-Jakob disease (CJD) ( BMJ 2002;32:1055).

The incident occured last year in Middlesbrough. It was feared that 24 patients might have been exposed to a risk of CJD by being operated on with equipment previously used in a …

Terahertz (THz) transmitter employing optical frequency comb can provide high quality THz carrier, and is useful to the future broadband THz communication systems based on coherent transmission technique. To achieve coherent transmission, it is important to evaluate the signal quality of a THz transmitter, and we derive error vector magnitude (EVM) including optical impairments of the optical frequency comb. The calculated EVM is in good agreement with simulated one, and practical requirements for EVM are indicated.


The National Geographic Society Center for Sustainable Destinations Stewardship Scorecards for 2003 and 2006 compared ratings by "experts" for 33 World Heritage Site destinations. Nine (27.3%) improved by four or more points and six (18.2%) decreased by four or more points in the three years. In 2006, local stakeholders rated these World Heritage destinations using the same criteria as the experts. Stakeholders rated six destinations (18.2%) lower and almost half of the 33 destinations (48.8%) increased by five or more points. A moderate positive correlation was determined between the ratings of the experts and stakeholders. Comments by experts and stakeholders related to each of the scorecard criterion measures were analyzed. ANOVA and t-test were performed to examine the six stakeholder categories ratings for each of the six criteria and the results are presented. The assumptions and limitations of the survey methodology are discussed along with recommendations for improving the Destination Stewardship Scorecard Survey.


The invention relates to a shaft seal. The shaft seal has a sealing element made from polyfluorocarbon, where the sealing element is provided with a sealing lip which is fitted at a surface to be sealed under radial force. The sealing lip is loaded in the direction of the surface to be sealed by an elastomer element in order to keeping the tightness of the shaft seal unchanged during using a seal under the circumstance of simple structure and saving cost. The sealing lip leans against the surface with an enough force all along. If the material of the sealing element creeps, the radial pressing force of the sealing lip cannot be affected, since the elastomer member is used for always pressing the sealing lip against the surface to be sealed with an enough pressing force.


By the aid of the assistance functions,we prove several expanded properties of ξfunction. We expect that these results are helpful to the study of statistics and stochastic process theory.


Since the famous Ju Toy Case in America and the equally famous Arlidge Case in England, there has been considerable apprehension that administrative law, as it is being developed, is gradually encroaching upon a fundamental safeguard of the liberty and property protected in England by "the rule of "law" 3 and in America by the due process clauses of the Constitution. 4 From an inarticulate training or perhaps from intuition the average Anglo-American had apparently come to feel that the fundamental law of the land requires some sort of judicial review of those administrative determinations which seriously affect one's rights with respect to liberty and property. When, therefore, he was told by the courts that one's most important rights with respect to liberty and property may, under some circumstances, be determined by administrative officers without any right of judicial review, or with a very limited'right of review, he was instinctively inclined to be somewhat apprehensive. Within the last year, however, the United States Supreme Court, partly perhaps as -a result of this apprehension, has handed down a highly important decision" in which the Court practically eliminated the margin of finality which had apparently been accorded

Then the bigger contribution factor was determined. Subsequently,the research series were simulated and predicted using the GM(1,1) model in this paper. This results reflected dynamically the development trend of Liaoning agricultural industrial structure and provided theories basis for the sustainable development of agricultural economy and scientific decision.


Two factor analyses were conducted on the functions that master's level clinical psychologists perform, and on their employers' preferred training models as indicated by questionnaires returned from 400 mental health agencies west of the Mississippi River. The first analysis, for all facility types, extracted seven factors which were labeled Outpatient Therapy, Inpatient Therapy, Community Mental Health, Research Assistant, Inpatient Ward Management, Psychological Testing, and Other Functions. A second factor analysis on the data returned from community mental health centers produced six factors: Outpatient Therapy, Inpatient Therapy, Ward Management and Research, Research Assistant, Psychological Testing, and Community Mental Health. The factor structures of the two analyses were quite similar in terms of their apparent meanings. The results of this study support the belief that master's level clinical psychologists are performing traditional clinical functions such as psychotherapy, psychological testing, and research, as well as functions associated with the more recent community mental health model. The results were viewed as an important step toward more rational, job-oriented curriculum development for master's level clinical psychologists.


The paper examines an iron sword and a bouterol made of horn found in one of the Urartian sites of Rusa son of Argishti – Rusahinili period in front of Mount Eiduru (Ayanis). The sword is a specimen of a blade weapon of nomads of the period of Near Eastern campaigns – an akinax of the Early Scythian Kelermes type. The archaeological context allows us to date the sword no later than 650 BC. It is assumed that the sword from Ayanis was acquired during the western military campaigns of Rusa II and can be regarded as a gift of one of the Cimmerian "chiefs" to King Biannini.
Based on the workmanship and technique of the "staff" of Queen Qaquli from Ayanis, as well as the swords found at Kelermes and Melgunov, it can be assumed that all these objects were made in an Urartian royal workshop. The swords from Kelermes and Melgunov are dip-lomatic gifts of Tsar Biannini to the Scythian chiefs who led the nomads in an alliance with Urartu, or a token of the imminent conclusion of an alliance. The fact that Urartian toreutic craftsmen inscribed the dynastic emblem of Urartian kings (I.M. Diakonoff) on the sword scab-bards of nomads rather indicates that in the eyes of Urartian donors their future owners were considered almost equal in rank to the owner of the Tushpin throne. This does not exclude the possibility that the covers could have been made during the reign of Argishti II.


In this paper, hyperaccumulator straw (Solanum nigrum L., Amaranthus chinense L., and Siegesbeckia orientalis L.) and phosphate rock powder were selected as materials, a pot experiment was used to study the effects of three compounding modifiers on the growth, nutritional quality and cadmium (Cd) content of Chinese cabbage. The results showed that: (1) The combination of Siegesbeckia orientalis + phosphate rock powder can significantly promote the growth of Chinese cabbage, while Solanum nigrum + phosphate rock powder and Amaranthus chinense + phosphate rock powder have no effect on the growth of Chinese cabbage. (2) The combination of Solanum nigrum and phosphate rock powder increased the content of soluble sugar, soluble protein and VC in shoots of Chinese cabbage by 64.33%, 16.27% and 2.2%, respectively, and the nitrite content decreased by 34.58%, which improved the quality of Chinese cabbage. (3) Different compounding modifiers can significantly reduce the Cd content in shoots of Chinese cabbage, and the reduction of Solanum nigrum + phosphate rock powder is the largest, reaching 61.29%. In conclusion, all three modifiers can improve the nutritional quality and reduce the Cd content in the shoots of Chinese cabbage, and Solanum nigrum + phosphate rock powder has the best effect.


An Automatic cooling and fire control system for truck chassis is presented in this paper, based on ultra-low power micro controller and infrared thermometer. The design uses the infrared thermometer to acquire the real-time temperature data, the micro controller to deal with measurement results, spray water or fire extinguishing agent to cool the chassis through the electromagnetic valve switches and alarm timely. The system can automatically control the chassis's temperature in reasonable range and play an important role in ensuring safety of long distance transport.


Most of the natural colourants used for dyeing fabrics were extracted from plants by boiling technique which required long extraction time and plenty of water. In this study, a rapid and eco-friendly extraction method (SWE) using water at different elevated temperatures was introduced to extract natural dyes. The results showed that a more concentrated sample extracts with higher intensity of colour was produced by SWE compared to boiling method. The silk fabrics dyed with sample extracts obtained by SWE at different temperatures gave a variety of colour shades and has a comparable colourfastness on washing and rubbing based on Malaysian Standard Testing Method (MS ISO 105). SWE has a good potential to be introduced to textile dyers as it is rapid, simple, inexpensive to perform and environmental friendly.


Abstract : A 750 hour simulated mission endurance test (SMET) cycle which will closely represent the expected in-service engine duty cycle for the F18 power plant has been developed. The test cycle evolved from an extensive investigation of Navy and Marine fleet engine operating conditions experienced in fighter and attack aircraft during shorebased and carrier operations. The test cycles reflect power lever movements that are an order of magnitude greater than originally thought, and incorporate a representative distribution of time at intermediate and augmented power. It is concluded that this SMET will aid the overall development process to substantiate the suitability of a new engine for service introduction. (Author)


TheOutstandingFruitCultivarAwardisamedalpresentedannuallybytheFruitBreeding WorkingGroupofthe American Society for Horticultural Science (ASHS) for noteworthy new fruits released over the previous 35 years. Since 1987, 38 cultivars have been recognized with medals presented at the Annual Conference of the Society. The awards celebrate the progress achieved by fruit breeders and their contributions to the world's fruit industry. The world's fruit industry is based on distinct clones that have uniquely desirable horticultural characteristics. The genetic im- provement of fruits known as fruit breeding in its broadest sense has an ancient tradition that dates back to the domestication process of the Neolithic and Bronze Age, 8,000 to 10,000 years ago. Genetic improvement was achieved by selection, first from natural seed- ling populations and then from seedlings that occurred naturally in growers' fields with de- sirable genotypes fixed by vegetative propa- gation. In the middle of the 19th century, the English horticulturist Thomas Andrew Knight (1759-1838) initiated the science of fruit breeding by a combination of deliberate hy- bridization followed by selection and testing. Conventional fruit breeding is based on con- tinuous selection of superior phenotypes from genetically variable populations using cycles of hybridization and selection and including special techniques such as mutation induc- tion, interspecific hybridization, and back- cross breeding. Recently, biotechnological techniques have been used including in vitro propagation, embryo rescue, protoplast fu- sion, marker-assisted selection, and transgen- esis. The creation of new distinct cultivars as a result of the breeder's art has had an enor- mous influence on pomology and horticul- ture. Trait improvements have been associated with characters that are beneficial to con- sumers such as the improvement of edible quality and appearance and to growers, packers, and processors such as resistance to diseases and pests, increased yield, and postharvest quality.

ABSTRACT Objective This study aimed to examine race and apolipoprotein E-e4 allele (APOE-e4) status differences in the longitudinal associations between loneliness and cognitive decline. Methods The study sample is composed of participants (N = 7696, 64% Black participants and 36% White participants) from the Chicago Health and Aging Project, a population-based cohort study. Mixed-effects regression models were conducted to examine the longitudinal associations between loneliness on global cognitive function and individual tests of cognitive function. Models were also stratified by race and APOE-e4. Results A greater percentage of Black participants (17%) reported loneliness at baseline visit compared with White participants (12%). Black and White participants who were lonely individuals had a similar rate of decline in global cognitive function at 0.075 (95% confidence interval [CI] = −0.082 to −0.068) standard deviation unit (SDU) per year for Black participants and at 0.075 (95% CI = −0.086 to −0.063) SDU per year for White participants. Lonely participants with APOE-e4 had a higher rate of global cognitive decline at −0.102 (95% CI = −0.115 to −0.088) SDU per year than for lonely participants without APOE-e4 at −0.052 (95% CI = −0.059 to −0.045) SDU per year. Conclusions The burden of loneliness and its relation to cognitive decline is higher among participants with APOE-e4 compared with those without APOE-e4. Loneliness is associated with cognitive decline in both Black and White participants.


Disclosed is an apparatus and method for controlling the power supply of a set-top box for a TV, wherein the wasting of unnecessary energy is minimized and an IPTV or a satellite reception TV can be used more conveniently. The disclosed apparatus for controlling the power supply of a set-top box for a TV comprises: a motion detection sensor detecting a motion; a data storage device in which firmware for controlling the power supply is stored; and a power supply controller that automatically controls the power supply of the set-top box based on whether a certain button and a power supply button are pressed or the duration for which said buttons are pressed, or based on the motion results of the motion detection from said motion detection sensor, while the firmware for controlling the power supply, which is stored in said data storage device so as to control the power supply, is extracted. User convenience is improved by separating signals for turning on the power supply and for placing the latter on standby using the firmware so as to control the power supply, and by using the motion detection sensor to automatically turn on the power supply while the latter is in a standby state.

Conclusion There was close relationship between PP and endothelial functionof brachial artery and PP was a more effective index to evaluate and forecastendothelial function of artery in patients with essential hypertension.


The biographer of Vincent Massey faces a considerable challenge. A combination of financial independence, social background, and personal energy made Vincent Massey a man of eclectic interests. Diplomat, political organizer, benefactor, educator, amateur actor, and patron of the arts Vincent Massey covered a great deal of ground. Such a diversity of interests would be difficult enough to chronicle were they followed in sequence. When, as was often the case with Massey, they were pursued simultaneously, there is the danger that any attempt at biography will result in numerous anecdotes which, ultimately, tell little of the man or his age. Moreover, Massey's personality is as complex as his interests. On the one hand, he was an extreme Anglophile who revelled in the attention of the English aristocracy and who saw Oxford as the centre of the intellectual universe. He was also somewhat of a snob and his strict aesthetic and social

Our work consists in elaboration and characterization of cadmium sulfide (CdS) thin films. Indeed, in order to deposit a series of these films, we have adopted a simple and cheap technique, such as the chemical bath Deposition (CBD). The series of samples of CdS was deposited on glass substrates by varying the deposit bath temperature from 55 to 75 ° C and by keeping the deposition time fixed (25 min). Our investigation is focused on the understanding and study of the effect of the deposition temperature on the physical properties of the thin films to which it was referred. For this purpose, we used two characterization techniques which are: the X-ray diffraction (PANalytical X-ray diffractometer) for determining the structure of the films and also, the UV-Vis spectroscopy (UV-3101 PC-SHIMADZU double beam spectrophotometer) for determining their optical properties. Thicknesses (d) of CdS films was measured with gravimetric weight different method using a sensitive electronic microbalance and were confirmed by using a profilometer of the type KLATENCORP6. The structural characterization indicates that the structure of CdS films obtained is cubic or hexagonal with preferential orientation in accordance with the plane (111) or (002), respectively. The optical characterization shows that these films have a fairly high transparency which varies between 55 and 80% in the visible range of the optical spectrum, the optical gap value of which can reach 2.2 eV. It can be suggested that these properties make these films perfectly suitable for their use as window film in solar cells in thin films.


Play is one of the most acute problems of modern preschool pedagogy. Value of play for child development is recognized by virtually all experts. However, there is a tendency to remove play from pre-school education. One of the causes of displacement of the preschool play is the uncertainty of the concept of "play". Despite the familiarity of the term, its meaning is understood and interpreted differently. This issue is addressed in the article in a detailed way. Different approaches to the understanding of the play from the point of view of psychologists are described. Special attention is given to play where there is no role, but there is an imaginary situation in which the child acts "not from things but from thought." The author extends the concept of the play and brings different kinds of visual games.


Human telomerase reverse transcriptase(hTERT),a catalytic subunit of telomerase,is highly expressed in a vast majority of cancer cells,but not in most normal adult cells,which makes it a broadly applicable molecular target for cancer immunotherapy.T cell epitope-based vaccines make use of T-cell epitopes from tumor antigens,and have its own unique advantages in cancer immunotherapy.The T-cell epitope peptide vaccine derived from hTERT can efficiently evoke specific cytotoxic T lymphocytes(CTL) responses,and has exhibited its anti-tumor effect in vivo in mice.Now it has already been put into experiment on human beings and displayed a good application prospect.

 In patients with persistent atrial fibrillation (PeAF) and heart failure with reduced ejection fraction (HFrEF) current guidelines recommend treatment of AF with catheter ablation (CA) (1). Recurrence of either AF or atrial flutter, often requiring additional procedures, are not uncommon, thus optimal long-term treatment of these patients is still unknown. Recently conduction system pacing (CSP), with more physiological ventricular activation, has made the ''pace and ablate'' strategy an attractive alternative for the treatment of PeAF refractory to medical therapy (2).

 Long term data comparing CA with conduction system pacing and AV node ablation (CSP/AVNa) for treatment of patients with PeAF and HFrEF is lacking. Hence, we sought to compare clinical outcomes of both treatment modalities.

 In a retrospective study consecutive patients under 75 years of age, with PeAF and left ventricular ejection fraction (LVEF) less than 50%, treated with CSP/AVNa from 2018 to 2021 in UMC Ljubljana were included. A control patient treated with CA for PeAF matched in age, sex and LVEF was assigned for each included CPS/AVNa patient. Both groups were compared for procedure-related characteristics, echocardiographic parameters, hospitalisations for heart failure and all-cause mortality.

 Among 771 patients referred for interventional treatment of AF, 23 patients treated with CSP/AVNa were included and compared with 23 CA matched controls. The general characteristics of both groups are summarised in Table 1. The mean follow-up was 20 ± 10 and 21 ± 8 months for CPS/AVNa and CA group, respectively (p=0.76). In CPS/AVNa group 83% received his bundle pacing and 17% left bundle branch area pacing. A selective CSP was achieved in 43% of CSP/AVNa patients. In addition to pulmonary vein isolation, additional ablation lines were performed in 35% of patients in the CA group. Significant improvement in LVEF was observed in both groups, 12% ± 11% (p<0.001) in CSP/AVNa and 21% ± 12% (p<0.001) in CA group. Hospitalisations for HF were rare during the follow-up, with 9% in CSP/AVNa and 4% in the CA ablation group (p=0.561). All-cause mortality was 9% in CSP/AVNa and 0% in CA group (p=0.153). However, major comorbidities were more common in the CSP/AVNa group than in the CA group, 3.4 ± 1.6 and 2.3 ± 1.5, respectively (p=0.017). Procedure-related characteristics are summarised in Table 1. In each group, 2 minor procedure-related adverse events were observed: 2 acute rises in pacing threshold post-AVNa in CSP/AVNa group and puncture site hematoma and transient pericardial effusion in CA group.

 In patients with PeAF and HFrEF, CSP/AVNa treatment strategy seems to derive similar clinical outcomes compared to CA approach. Larger prospective randomised data are needed to further confirm these initial findings and determine optimal long-term treatment strategy for this group of patients.


Objective To assess the clinical application value of impedance monitoring in the evaluation of mucosal barrier function by correlation analysis between esophageal impedance baseline and acid exposure, epithelial intercellular spaces(ICS) in patients with non-erosive reflux diseases(NERD). Methods A total of 46 NERD patients admitted to China-Japan Friendship Hospital from 2013 to 2014 and 18 healthy controls were enrolled in the study. All patients bad underwent 24 h p H-impedance monitoring and gastroendoscopy one week apart. Two biopsies were taken from the distal esophageal walls and ICS was quantified by histochemical technique. Results Patients with NERD had longer acid exposure time [4.1(0.2-0.6)% vs 0.4(1.0-5.3)%, P 0.001], lower impedance baseline of distal esophagus [(2 943±759)Ω vs(3 968±1076)Ω, P 0.001] and wider ICS [(1.01±0.20)μm vs(0.67±0.14)μm, P 0.001] than controls. Baseline impedance was negatively correlated with AET(r=-0.35, P=0.016) and ICS(r=-0.58, P=0.002) in NERD patients. Conclusion The decrease of distal esophageal impedance baseline in NERD is associated with acid exposure and dilated intercellular spaces. Impedance monitoring can be used to assess esophageal mucosal integrity.

Selecting transparently a proper network connection for voice communication will be a fundamental requirement in future multi-mode heterogeneous wireless network. This paper extends always best connected (ABC) to a fine-grain paradigm called always best network connection (ABNC) to address this issue. Instead of selecting a best access network as in conventional ABC, ABNC enable users to select a best network connection, which consists of source and destination access network pair, to satisfy quality constraint and users' preference. To support ABNC, we develop a user profile to specify network connection priority. Meanwhile we extend SIP and propose a network selection information service (NSIS) based on MIH (media independent handover) to collect information of both source and destination access networks for decision making. Finally, analytic hierarchy process (AHP) is used to recommend a network connection with assistance of user profile and NSIS. An example is illustrated to show that AHP can successfully select a good network connection that fulfill the requirement of users.


Due to the emergence of ICT in ELT sector, seasoned English teachers find it resistant to such a shift despite having a positive attitude towards its use. This quasi-experimental study aimed to examine the extent to which seasoned English language teachers developed their ICT skills through a Service-Learning Activity (SLA). Using a one-group pre- and post-test design, this study collected the data through a modified Needs Assessment Survey (NAS) distributed to fourteen purposively selected participants. It was administered to examine what professional ICT development would greatly benefit them. The data were analyzed using descriptive statistics and themes according to the Service-Learning Activity (SLA) topics. A Post Evaluation Survey (PES) was administered, and its result was compared to the initial test. The results showed that the seasoned teachers gained significant learning gains in terms of (1) sharing of knowledge from other teachers; (2) being encouraged to use ICT tools; (3) training opportunities; (4) working with other colleagues; and 5) attending professional workshops which include SLA. However, this study unveiled that the English teachers had no significant difference in perceptions regarding the roles of computers in teaching before and after the intervention. Limitations and recommendations for future studies were discussed

The Body of the Patient
Emotions, power and reciprocity in the world of transplantation

Markus Idvall

Transplantation has been a part of human culture and imagination over centuries. In modern times, from the mid-20th century on, transplantation of solid organs and cells has become part of clinical practice. In this article, I focus on field studies with 1) individuals who have donated a kidney to a relative (living donors) and 2) individuals who have received a kidney from a deceased donor. Transplantation is problematized as a form of inter-corporality and a performative meeting between a recipient, a donor and medical intermediaries in the shape of doctors and nurses. By focusing on the body of the patient we learn about the aspects of emotions, power, and reciprocity in which the transplantation takes place.
The empirical discussion starts with a phenomenological approach towards what it means to have a transplant. In the narrative of one of the interview subjects a specific landscape – a forest – appears as a symbol for the individual body's transformation or even "rebirth". The embodiment of the forest signifies both hope and an uncertain future for the individual. In a similar way, individuals who donate one of their kidneys to a relative, also incorporate the patient's room in the hospital as being a space representing the pain which an individual living donor experiences when temporarily becoming a patient.
In the second part of the article, a bio-political, power-related perspective is included in the analysis. The medical gaze that identifies donors and recipients is discussed in relation to how the human body and body-parts become a form of a national resource in the transplant context. Donor pools and waiting lists for transplants are in this respect tools for realizing a transplant industry on a national and global basis. At the end of the article, reciprocity is introduced as an analytical perspective. By distinguishing the transplant as a gift, emotions, power relations and the multifaceted body of the patient can be seen as inter-connected.


Background and Objective: Anaerobic bacteria are the main cause of periodontitis. It has been shown that green tea and black tea have antibacterial effect. The aim of this study was to determine he antibacterial effect of Iranian green tea and black tea against Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis and Prevotella intermedia. Methods : Aqueous and methanolic extracts of Iranian green tea and black tea at concentrations ranging from 10 to 500 mg/ml were tested against standard strains of A. actinomycetemcomitans (ATCC 33384), P. gingivalis (ATCC 33227) and P. intermedia (ATCC 25671) using agar disk diffusion, broth microdilution and determination of minimum inhibitory concentration. Results: P. gingivalis, A. actinomycetemcomitans and P. intermedia were sensitive to the methanolic extract of Iranian green tea at concentrations of 100-500 mg/ml, 10-500 mg/ml and 50-500mg/ml, respectively. P. gingivalis, A. actinomycetemcomitans and P. intermedia were sensitive to the methanolic extract of Iranian black tea at concentrations of 200-500 mg/ml, 20-500 mg/ml and 200-500 mg/ml, respectively. In addition, P. gingivalis, A. actinomycetemcomitans and P. intermedia were sensitive to the aquatic extract of Iranian green tea at concentrations of 200-500mg/ml, 100-500 mg/ml and 200-500 mg/ml, respectively. Conclusion: The aquatic and alcoholic extracts of Iranian green tea and black tea have antibacterial activity against A. actinomycetemcomitans , P. intermedia and P. gingivalis . Therefore, incorporation of Iranian black tea as an effective native herb could be beneficial for prevention of oral cavity diseases.


Introduction Polyurethane is a synthetic polymer that is formed by condensation polymerization reaction between polyisocyanate and polyol having intramolecular urethane bonds. Urethanes are derivatives of carbamic acids which exist only in the form of their esters. Including polyol and polyisocyanate other raw materials used in the synthesis of polyurethane are catalysts and auxiliary materials. Auxilliary materials include chain extension agents (e.g short-chain diols), crosslinking agents (e.g short chain polyol with three or more hydroxyl groups) that react with isocynate groups, addition agents for the PU manufacture process and improvement agents (e.g silicone compounds used as antifoams and aromatic esters as flexibilizers). Polyol, can either be of ester or ether type. The PU polymer that contains an ester type polyol is known as polyester PU, whereas the PU polymer that contains an ether type polyol is known as polyether PU. Similarly, polyisocyanate can also be either aliphatic or aromatic type (Gautam et al., 2007). Among these, tolylene diisocyanate and diphenylmethane diisocynate are the most commonly used. In all types of PU polymers, the polymer backbone mainly contains urethane bonds. Applications of Polyurethane PU is used in a variety of industrial applications, including insulating foams, fibers, and synthetic leather and rubber goods. Auto manufacturers are replacing latex rubber in car seats and interior padding with PU foam because of lower density and greater flexibility (Ulrich, 1983). Polymer is widely used in liquid coating and paints, adhesives, sealants, flexible and rigid foams, and elastomers (Center for polyurethanes industry 2007). Polyurethane can be used in furniture, constructional materials, and synthetic skins (Howard, 2002). PU has increased tensile strength and melting points making them more durable (Bayer, 1947). Rigid PU foam is used as water heaters, insulation for buildings, commercial and residential refrigeration, for floatation and for energy management. Flexible PU foam is irreplaceable in the industry of furniture, bedding, carpet, packaging and machinery. Thermoplastic PU is highly elastic, flexible and resistant to many environmental factors, that is why it has found its applications in footwear production, wire and cable coatings, architectural glass lamination, auto-body side molding, medical tubing and biomedical apparatus etc. (Szycher, 1999). Hazards of Polyurethane Health effects of isocyanate exposure include irritation of skin and mucous membranes, chest tightness, and difficult breathing. Isocyanates include compounds classified as potential human carcinogens and known to cause cancer in animals. The main effects of hazardous exposures are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin. Objectives The objectives of the study are: 1. To isolate and identify polyurethane degrading bacteria from soil. 2. To check the activity of enzymes (esterase's and lipases) involved in degradation of polyurethane. 3. To study the effect of pH, temperature and presence of cometabolites on the biodegradation of PU by bacterial consortium. Literature Review Biodegradation of polyurethane Different samples of polyurethane have different degradation patterns due to many properties of polyurethane such as molecular orientation, crystallinity, cross-linking, and chemical groups presented in the molecular chains which determine the accessibility to degrading enzyme systems (Pathirana and Seal, 1983). The microbial degradation process of PU can roughly be divided into the degradation of urethane bonds and into the degradation of polyol segments, which are the special constituents of PU, and degradability is mainly influenced by the chemical structure of the polyol segment (polyester type or polyether type) (Nakajima-Kambe et al., 1999). PU with long repeating units and hydrolytic groups would be less likely to pack into high crystalline regions as normal polyurethanes, and these polymers were more accessible


Along with the development of information, science and technology, there is a quite popular developing resampling method, namely bootstrapping. Bootstrap estimates asymptotically against its original value (observation). Thus, the greater bootstrap replication, the resample distribution will be normally distributed. It indicates that the bootstrap estimator gives better results. Based on the goodness-of-fit test by using Kolmogorov-Smirnov test, the severity on fire insurance data follow Weibull 2 parameter distribution. A case study is conducted on reinsurance company's data for shopping centre's fire. It is a big data. Since it is a reinsurance company's data, the data completeness may be inadequate. It causes the severity claim to be processed using semiparametric bootstrap.

This is more a methodological paper on the issue of state support rather than a recipe for subsidizing metallurgy. The topic is timely, because the Parliament has to decide on the program (10 year plan) for metallurgy. Discussions in the last months made clear, that there is no coherent attempt to justify state support and develop the appropriate means accordingly. In particular, the Ministry of Industrial Policy (responsible for the program) largely argues in Soviet style: "Helping metallurgy is helping the state". The addresses of the paper are foremost the committee in Parliament as well as parts of the Ministry of Economy that is more aware of the problems in the design of state support.


Learning listening will assist us in improving another targeted skill considerably. People demand to hear several types of English repeatedly and continuously if they want to communicate appropriately, meaningfully, and naturally. The objective of this paper is to explore. The importance of listening strategies, The strategies in teaching listening, and listening processes, especially Bottom-up and top-down strategies. Another purpose of writing this paper is to show teachers how they can influence students' learning process—notably, using strategies to make it easier for students to learn listening.


Simulation models are integral to IT solutions built according to the Industry 4.0 concept. They are often the basis for developing digital twin solutions, which is why development environments are constantly developed and improved to meet the growing requirements of manufacturing enterprises. This work presents the development and verification of a simulation model of an automated assembly line located in the Smart Factory laboratory of the Poznań University of Technology. One of the criteria for designing the assembly process on this line is the time it takes for transport pallets to pass through individual stations. The work is a response to the need to quickly analyze the designed product assembly scenarios to choose the best one. The operation of the automated line with six assembly stations and allowing for the simultaneous transport of six pallets were considered. The main purpose of the work was to build a simulation model that would allow us to obtain assembly times close to real. The model was created using the Tecnomatix Plant Simulation 16.0 software, and verification work was carried out through a comparative analysis of the results of the simulation time of various assembly scenarios in relation to the actual operation of the line.

We also greatly appreciate the authors who put the time and effort to address the reviewers' comments and provided detailed responses to the reviews that helped the reviewers and editors make the final decision. During this first year of ACS Polymers Au, we, as editors, have come to appreciate that the journal's success lies in the hands of the journal's primary stakeholdersauthors and reviewers. We also understand that the impact factor of this journal will eventually be dictated by the readers who cite the publications published in the journal, but it all starts with the authors and reviewers. This hasmotivated us to connect with these two growing groups of ACS Polymers Au stakeholders with this editorial where we share some good practices that we have seen from the reviewers and authors. The ideas expressed in this editorial are clearly biased by our own preferences and experiences and our likes and dislikes, but we believe most of these good practices are generic enough to be applicable for other peer-reviewed journals as well. We also hope this editorial will serve as a guidance for many of the early career authors and reviewers.


Magnetic Particle Imaging (MPI) allows rapid imaging of magnetic tracer distributions with high sensitivity. We show volumetric in vivo heart images of a mouse. The concentration of the commercially available MR contrast agent was in a range which is approved for humans. Images at various stages of the cardiac cycle were reconstructed proving the unprecedented temporal resolution of MPI. The results suggest that MPI can be scaled up to human sized scanners enabling, e.g., dynamic imaging of coronary blood flow.
