With the aging of China's population, the retrofitting of elevators in existing multi-story residential buildings has been steadily promoted with the support of the government, but the regulations and policies guiding the retrofitting of elevators have not been able to solve the disputes related to compensation relief, cost sharing, and safeguard measures well. The existing types of disputes are mainly civil and administrative. After searching and analyzing, civil disputes can be divided into three categories: nuisance removal, economic loss, and procedural defects, and in practice, there are problems with different standards for judging the eligibility of litigation subjects, limitations of litigation by low-rise owners, and lack of compensation mechanisms. Based on the current situation of retrofitting elevators to existing multi-story residential buildings in Tianjin, this paper analyzes the existing dispute resolution paths from the balance of interests of relevant subjects to promote the implementation of retrofitting elevators to existing multi-story residential buildings.

In many multi‐sensor, single‐source applications noise interferes with cleanly recovering the source. Various approaches have been designed to recover sources in interference, but most of them require prior knowledge or assumptions that limit their applicability to real‐world environments. We present a novel and practical frequency‐domain method for blindly recovering a single, nonstationary, high‐kurtosis source in arbitrary low‐kurtosis interference using a narrowband kurtosis objective. This method handles convolutional mixing, does not impose a theoretical limit on the number of interferers, and relies only on the kurtosis properties of the source and interference. A kurtosis‐based objective is used to compute instantaneous filter weights in each frequency bin, since linear combinations of speech with low‐kurtosis interference tend to have lower kurtosis than speech alone. The set of bin‐by‐bin scale factors needed for the total spatio‐temporal recovery filter are computed by using estimated steering ...


This study aims to identify the impact of COVID-19 on audit quality based on the investigation of three auditing aspects, namely: audit fees, audit procedures, and auditors' salaries in Saudi Arabia and Yemen. For data collection, fifty-five (55) questionnaires were distributed to internal auditors, external auditors, managers of audit offices, and financial managers. Eleven managers of audit offices and auditors were interviewed. A descriptive, regression analysis, and T-test were used. The study results reveal that the audit quality has been significantly affected due to the devastating effect of COVID-19 on audit fees, audit procedures, and audit staff salaries. In addition, the results show that Yemen is severely affected due to several factors, which include a lack of modern auditing systems. Also, private ownership of establishments and the absence of laws for determining audit fees negatively impacted the audit quality. Being the first of a practical kind, this study provides a significant contribution to the existing literature on the impact of COVID-19 on the quality of auditing. This would be useful for corporations, audit offices, auditors, and researchers. Moreover, this study can bridge the identified research gap on this topic and provide empirical evidence about the impact of COVID-19 on audit quality. Doi: 10.28991/esj-2022-SPER-06 Full Text: PDF

ABSTRACT The isothermal hot compression tests of 20CrMnTiH steel were carried out by using Gleeble-3500 thermo-simulation-machine at deformation temperatures ranging from 1123 to 1423 K and at strain rates ranging from 0.01 to 1 s−1. The microstructural characteristics after hot compression under various deformation conditions were described with optical microscope and EBSD method, meanwhile the Vickers-hardness (HV) corresponding to the samples was measured. The strain-induced fine and uniform recrystallised grains instead of the original coarse microstructure and higher hardness were obtained with increasing strain rate and decreasing deformation temperature. The average misorientation angle got increased and an intense α-fibre texture was dominated with increasing temperature, and then the angle decreased when the temperature increase to 1423 K. By introducing Zener–Hollomon (Z) parameter, the relationship of recrystallised grain size (D) and HV under different Z values were generated. The relationship of 20CrMnTiH steel recrystallised grain size (D) and HV was formulated based on the analysis of the experimental data, which is in agreement with Hall–Petch relationship.


Permeation of electroactive organic probes through an electroinactive and passivating poly-o-phenylenediamine (PPD) film electropolymerized on Pt and glassy carbon (GC) electrodes has been investigated by cyclic and rotating disk electrode (RDE) voltammetry. The access of solutes to the metal-polymer interface appears mainly governed by specific chemical interactions, influencing partition, and diffusion phenomena, rather than by exclusion effects based on molecular size or charge. Potential cycling of the film induces fine modifications in the chemical/physical structure of the polymer, as evidenced by electron spectroscopy for chemical analysis (ESCA) measurements and by an enhanced permeation of certain solutes. The membrane is, however, stable in the pH and potential range usually employed in its application, that is, as an enzyme-entrapping membrane in amperometric biosensors; because of membrane permselectivity, the electrochemical response of the most common electroactive interferents is deeply depressed.


The central component of most knowledge-based Human Resource Management (HRM) systems is a model of the actual or required knowledge and abilities of employees, applicants and job positions. The notion of competence has been used in many of them to describe levels of skills and knowledge as applied to concrete work situations. Nonetheless, the imprecise nature of relationships and interactions between competences has been neglected in existing approaches. In this paper, a model for imprecise gen-spec and composition relationships between competences is described, aimed at coming up with more detailed and realistic selection processes. A concrete case study is also described, illustrating how the Hr-Xml canonical format for competency definition and interchange can be extended to give support to those relationships.


Summary Title : Parenting, social context, play. The following paper presents the partial results of a Research Project financed by the University of Buenos Aires, under the Scientific Research Project Programming 2014-2017, UBACyT, project code 20020130200174BA "Type of attachment and attitudes towards children's play", which articulates with the University Extension Program "Neighbourhood Toy libraries ", Faculty of Psychology. The theoretical framework taken highlights the importance of play as an activity that has an irreplaceable value in structuring the psyche in accordance with the parental functions. We outline conceptualizations about the development sequence of recreational activity in the process of subjective constitution and the need for the "other" -through the maternal function- for  the deployment of the symbolization process and playful activities. This positions the intersubjective exchange, as logical precedent of the subjective constitution. In this work we include results obtained during the development of the present research. We expose them from a qualitative approach, and take into consideration the parental childhood play history and our involvement in educational and community contexts.

This article presents the central arguments made in a speech to the 39th UKSG Conference in April 2016, exploring how academic libraries and publishers can work together more effectively to deliver on our shared core mission – to foster access to the world's knowledge across disciplinary, institutional and national boundaries for researchers, students and academics alike. It examines how some straightforward changes to publisher practices might enable simpler workflows within libraries, thereby generating significant efficiency gains. It also presents evidence for the impact of long-term trends in library spending, budgets and staffing to demonstrate why it is that university libraries, and their institutions, cannot afford to continue to pay above-inflation increases for 'big deal' subscriptions, nor to pay twice for the same content in the form of hybrid journals. It argues that the publishers that embrace open access (OA), explore new business models and work with the higher education community to explore the transformative power of OA will reap long-term rewards.

The last few years the field of taxonomy learning has become more and more important in computer science. However it also has relevance in economics, as it can be used for describing economic domains as finances, macroeconomics etc. There are numerous methods to create a taxonomy from the Web, corpus, or semantic lexicon. This thesis examines the different steps of the investigated methods dealing with the process of taxonomy learning. These methods will be explained and compared throughout this thesis. The main methods that are discussed are term extraction through linguistic, statistic and hybrid filtering, synonym extraction, computing distance between terms, and deriving taxonomic relations through clustering, classification and lexico-syntactic patterns.


Oil exploration shows that dissolution porosity is the significant reservoir space type for carbonate rocks. Some authors propose that significant volumes of porosity are created by deep-burial dissolution. Others argue that this model is unsupported by empirical data and violates important chemical constraints on mass transport. In addition, previous studies focused on finding out the relationship between carbonate dissolution quantity and temperature and pressure, but ignored the evolution of pore structure and change of porosity and permeability, therefore, it is necessary to study dissolution patterns of carbonate rocks by experimental stimulation. In this study, hydrothermal flow experiments of single-pass injection of acetic acid were conducted on 60 carbonate cores to examine fluid-rock reactions in carbonate reservoirs under burial conditions. Preand postexperiment porosity-permeability measurement and pore structure construction by CT were conducted and compared. The porous dolostones with network pores were enlarged overall, pore volume and permeability increased accordingly, and the increased pores were mainly matrix pores; for porous limestones, after dissolution, although pore volume and permeability all increased significantly, favorable for the improvement of reservoir quality, but the increased pore spaces were relatively concentrated in fractures and caves; for fractured-porous dolostones and fractured limestones, dissolution led to the permeability increase of 2-3 orders of magnitude, but the increased pore volume was limited, and the main pore spaces increased were fractured pores. Under the condition increased from 30°C, 5MPa to 187°C, 60MPa, the sum of Ca2+ & Mg2+ concentrations of outflow fluids of carbonate rocks decrease from 21.58×10-3 mol/L to 8.90×10-3 mol/L. The dissolution quantity of porous dolomite decreases continuously and steadily to about 20% finally; while the dissolution quantity of porous limestone decreases slowly at first, then fast, then slowly and steadily, by more than 50% finally. Finally, conclusions are summarized: (1) Relatively shallow burial environment is more beneficial to the formation of carbonate scale dissolution pores; (2) Open system is of crucial importance in the development of large-scale dissolution pores; (3) The dissolution patterns of carbonate rocks are controlled by lithologies, pre-existing pore structures.

Anaphylaxis is the most severe manifestation of allergic disorders. The poor knowledge of its molecular mechanisms often leads to under‐diagnosis. MicroRNAs (miRNA) regulate physiologic and pathologic processes, and they have been postulated as promising diagnostic markers. The main objectives of this study were to characterize the human miRNA profile during anaphylaxis and to assess their capacity as diagnostic markers and determine their participation in the molecular mechanisms of this event.


THIS article is concerned with the type of multi‐cell box found in wings, fins and tail planes, etc. It does not include the effect of axial constraint applied to the box root inducing differential bending of the box spars, or the type of box whose individual cells have vastly different rates of change of cross sectional properties, i.e. a twin cell box with one cell remaining constant in area and the other tapering sharply—this type would require special analysis, in which the loads imposed on the internal ribs, due to their finite stiffness, would need investigating.


The Marine Park Area (MPA) in Malaysia is an attractive place to visit especially for the international visitors who seek for the natural beauty on the island. Due to the richness of coral species, the MPA was established in Malaysia since 1994 to protect these natural heritages and conserve the marine ecosystem. The number of visitors of MPA in Malaysia has increased for the last 12 years, from 10.22 million to 25.03 million between year 2000 and 2012. The overwhelming number of visitors visiting the MPA requires the management of MPA to increase the quality of services and facilities to meet the high expectation from the visitors. This study was aimed at measuring the level of visitor's satisfaction on service quality at the Pulau Tinggi and Pulau Sibu Marine Park Area located in Mersing, Johor. The total respondents who responded through face-to-face interviews in June 2014 involving 165 visitors. The data of this study were analyzed using descriptive analysis, gap analysis and Expectation-Perception Analysis (EPA). The results of this study revealed that there are negative gaps between expectation and perception from the visitors' perspective towards service quality provided by the MPA. Overall, the visitors of the islands were not quite satisfied with the services provided by the MPA. Therefore, the management of MPA needs to improve the quality of their services to attract more visitors visiting the islands.


In the first comprehensive textbook on prejudice with a strong psychological research base, Whitley and Kite cover a broad range of topics including race and ethnicity, gender, sexual orientation, and ageism. By integrating theory and research with students' own experiences, the authors increase students' awareness of influences that shape prejudices. As students are asked to evaluate research results and their personal, subjective beliefs, they develop an appreciation of scientific evidence regarding stereotypes, prejudice, and discrimination.


EC UN/ECE, 2000; De Vries, W., G.J. Reinds, M.S. van Kerkvoorde, C.M.A. Hendriks, E.E.J.M. Leeters, C.P. Gross, J.C.H. Voogd, E.M. Vel. Intensive Monitoring of Forest Ecosystems in Europe, 2000 Technical Report. EC, UN/ECE 2000, Brussels, Geneva, 191 pp. Apart from an overview of the implementation of the Intensive Monitoring Programme of forest ecosystems in Europe and the various methodological aspects involved in data evaluation, this Technical Report gives information on results obtained in surveys on crown condition, soil condition, foliar condition, atmospheric deposition and soil solution chemistry. It also includes examples from results related to remote sensing. The major aim of this year's report was to gain insight in element concentrations in view of critical chemical values and in relationships between results from the various surveys and environmental factors, in comparison to previously obtained results. Examples of aerial photography show that this technique can successfully be used to gain information on the representativity of stand characteristics, such as crown condition, stand height and stand structure, within the plot in comparison to the area surrounding the plot including time series of those characteristics. Major conclusions for the different surveys are: Both bulk and total deposition of N appeared to be higher than S deposition at nearly all the plots in 1997 and the average calculated total N deposition was approximately twice the S deposition. Atmospheric deposition was significantly influenced by the geographic region and to a lesser extent by rainfall, altitude and tree species. Stand age alone explained 5-36% of the variation in crown condition, depending on tree species. Apart from stand age, 15-30% of the variation in defoliation could be explained by the variation in precipitation, temperature, N and S deposition and foliar chemistry. At approximately 30% of the stands, the nutrient status of the foliage can be judged as insufficient and unbalanced for at least one nutrient. Atmospheric deposition, meteorological parameters, soil chemistry, and site characteristics all contributed to the explanation of foliar nutrient concentrations. The percentage variation accounted for generally decreased going from N> Mg> S> Ca> K> P. The foliar N and S concentrations of the coniferous species, especially pine, were significantly related to the N and S deposition. Nitrogen pools in the organic layer of forest soils varied mostly between 100 and 250 kg.ha.yr. Considering the net N input by deposition, a time interval of 10 years might give a significant difference in N pools for approximately 25% of the plots. Approximately 30-50% of the variation in element pools in the organic layer was mostly explained for by various stand and site characteristics, precipitation, temperature and pH. Concentrations of NO3 and ratios of Al to Ca+Mg+K, above levels that are indicative for adverse effects, occurred in the subsoil at some 10 – 40% of all plots, respectively. Those plots were mainly located in a transect from Finland to Spain. The variation in concentrations of major ions in the soil solution could to a large extent be explained by differences in atmospheric deposition and to a lesser extent by variations in precipitation and soil chemistry.


Pairing in a single-j shell is described in terms of two Q-oscillators, one describing the J — 0 fermion pairs and the other corresponding to the « 7 ^ 0 pairs, the deformation parameter Τ = In Q being related to the inverse of the size of the shell. Using these two oscillators an S U Q ( 2 ) algebra is constructed, while a pairing Hamiltonian giving the correct energy eigenvalues up to terms of first order in the small parameter can be written in terms of the Casimir operators of the algebras appearing in the U Q ( 2 ) D U Q ( 1 ) chain, thus exhibiting a quantum algebraic dynamical symmetry. The additional terms introduced by the Q-oscillator are found to improve the agreement with the experimental data for the neutron pair separation energies of the Sn isotopes, with no extra parameter introduced. * Presented by Dennis Bonatsos


This article intends to demonstrate how agroecologic practices has contributed with the producers of the municipality of Rio Grande-RS to remain cultivating the land and producing food products without harming the environment. This research is the result of Master's thesis held and defended at the Federal University of Rio Grande in 2011. We found that, within the local reality, agroecology contributes very much in offering quality food, as well as in the debate about environmental preservation. This research also intends to understand the processes, purpose and trends of agroecological production in the county. For this it was important to understand the organization of production, forms of producer associations and their relationships with public policy. To contribute to these considerations we sought to review some studies that emphasized the agroecologically-based production as an alternative for techniques of the green revolution. We seek also to highlight some initiatives to reduce dependence on external inputs and, consequently, to improve producer independence against market fluctuations. Importantly, in addition to bibliographic and conceptual survey were considered for the purpose of issue analysis, interviews and ideas presented by the interviewees producers, elected to the subjects of this research.

Stability is an important safety issues related to the use of mobile cranes. Dynamic loading related to crane motion and load are the key factors associated with the failure to maintain stability. In this regard, the dynamic nature of mobile crane operations entails a variety of outrigger reaction values for truck cranes and track pressure values for crawler cranes. Crane supporting reaction or pressure is a function of the lifting configuration, crane geometry, and the crane component's weight; in most situations, such information is not readily available. Moreover, this paper presents an algorithm which is designed to assist practitioners in evaluating the elements required for calculating the reaction forces for both types of mobile cranes—truck cranes on outriggers and crawler cranes on tracks—and checking the stability of the crane. The developed algorithm integrates a reaction influence chart, which accounts for the dynamic relationship between the reaction of the outriggers or pressure of the crawler tracks and the boom's horizontal swinging and vertical angles. The developed algorithm is also integrated with a previously developed crane selection system and a database. Finally, a case example is described in order to demonstrate the use of the presented algorithm. The proposed system has proven to be effective in reducing the time and cost associated with the preparation of lift studies.

Adaptive resource allocation with water-filling has been considered to be an efficient way of increasing data throughput for multicarrier systems. However, the water-filling technique usually requires perfect channel state information; thus, its application is very limited in wireless environments where only partial channel knowledge is available at the transmitter. A sub-band rate and power control algorithm is proposed as a sub-optimal scheme of resource allocation for wireless OFDM systems. We analyze the effect of Doppler frequency in the sub-band rate and power control algorithm and show the capacity increase with the proposed algorithm. We also extend the algorithm to multiuser cases. For both single and multiuser cases, the rate and power control is evaluated in two senses: ergodic capacity and outage probability.


much later, a far more assuaging teaching for many tortured souls than Arminianism. She also seems unaware that Calvinists, even supralapsarians, maintained that the reprobate were finally condemned on account of their sins, a formulation which she takes as rejection of reprobation (pp. 74, 177). Furthermore, she follows the older view of Perry Miller that language about covenantal obligation is crypto-Arminian (pp. 101, 179); but as Michael McGiffert has shown, covenant theology and the most emphatic double predestination were eminently compatible. Nor, while quibbling about theological misunderstandings, is it proper to use the formulation "salvation by faith alone" (p. 83); that which was by faith alone was justification, one part of the process of salvation. But these remarks do not undermine her main arguments; on the contrary, they suggest revisions of the argument which would enrich it (for example, the acknowledgement of a more thorough Calvinist character to Donne's thought might have illuminated its polarities). Thus, in spite of such cavils, this is an important and rewarding book which forces reconsideration of conventional readings of seminal figures, and makes religion really matter in our understanding of an earlier time.


Semantic integrity assertions are predicates that define consistent states. A database system enforces assertions by ensuring that consistency is maintained as the database is updated.Most research on the efficient enforcement of assertions has concentrated on assertion simplification algorithms --- algorithms that produce simplified assertions that can be evaluated before the update is executed. This paper describes a strategy for further improving the efficiency of assertion enforcement.We develop an efficient algorithm for evaluating an assertion produced by an assertion simplification algorithm. We characterize a class of assertions that can be evaluated using a simple two-step procedure. The first step defines and evaluates simple selection queries on each relation. The second step applies set emptiness tests to the results of these selections. We also show how these techniques may be used to improve the efficiency of evaluating assertions outside our class.


Objectives for the EVAC computer model are to simulate emergency evacuation from aircraft and thus to reduce or replace the practice of conducting live tests with a full passenger load, now required to demonstrate that emergency evacuation from a new airplane configuration meets regulatory criteria. Plans are to develop a model that demonstrates evacuation performance fidelity and credibility to the degree determined to be necessary for acceptance as a valid evacuation "test" method. This is being accomplished by developing a literal step-by-step simulation of the evacuation process. Resulting model performance elements are based on a time-line of evacuation performance events and queuing behavior similarly to task timeline analysis techniques. Features include ability to handle basic variables in the sequence of task events and also to modify performance time according to characteristics that may be individualized (e.g., age, sex, agressiveness) or related to features of the environment or systems (e.g., lights, obstacles, door size, number of slide lanes). Reported are present model features, performance capabilities and level of calibration.


X-ray diffraction from protein crystals remains the most reliable way to determine the molecular structure of proteins, and how this structure relates to biological function. However, we still lack the ability to predict solution conditions that support the nucleation and growth of high-quality protein crystals for X-ray diffraction studies. The overall goal of this thesis is two-fold: (a) determine the nucleation behavior and solubilities for lysozyme crystals with two distinct crystal structures (orthorhombic vs. tetragonal) and (b) investigate whether these changes in crystal habit and crystal solubility correlate with any discontinuities in the liquid-liquid phase boundary of lysozyme that occurs under the same solution conditions. We measured lysozyme crystal solubility by nucleating and subsequently dissolving very small lysozyme crystals in highly supersaturated solutions. The presence of crystals in our samples is detected and monitored by measuring the light scattered off the micron-sized crystals. These "turbidity measurements" are repeated across a range of protein concentrations, for pH 4.6 and 5.6, thereby


The invention discloses a repairing and strengthening method for existing reinforced concrete beam-column joints. The method includes steps of building up a platform around a repaired concrete frame column, reasonably constructing the steel tube scaffold of the platform, allowing the platform to be able to break down the stress load of the concrete beam-column joints, using a jacking support to support the beam above the concrete frame column, using an underpinning jack to jack and restore the beam bottom, when the beam reaches a required height, stretching the deformed top of the concrete frame column in the opposite direction to restore an original shape, repairing and solidly filling each hole on the concrete frame column and the beam-column joints, and pasting carbon fiber to reinforce and repair the cracks of the frame beam and frame column until all the flaws of the frame beam and frame column are repaired.


The article gives grounds for a new paradigm of development - branding of the territory. The problem of region brand formation is actualized. The point of view of the author on the territorial branding as a technology of providing the balanced and stable socio-economic territory development in current conditions deserves particular attention. The analysis of territorial branding formation as independent marketing trend is given. The scientific interpretations of the category "territorial branding" are given. The proposition that branding is an effective instrument of attracting attention to the territory is stressed. In conditions of informational and creative economy the existence of the city brand and its development strategies become the necessary factor of the effective realization of territorial potential. The conceptual framework of territorial branding and main characteristics of the utility of the territory are considered. The results of scientific research develop scientific knowledge in the field of branding territory theory, promote the development and use of intellectual and institutional resources of the territory for the growth of its marketing potential. This indicates, that the basic principles of territorial development, starting from the main concept to the specific project documents need updating, which is connected with the economic processes and also democratization and globalization processes. The cultural-economical planning gets priority, the foundation of it is the use of human and cultural capital of the city. The novelty is that material assets, traditionally considered being the basis of territorial economy development, lose their significance comparing to intangible assets, which are of various character: creative and cultural potential of the inhabitants, management professionalism, information environment saturation, the possibility to create the atmosphere of tranquility and comfort on the territory. Not the territory size and its economic base become the main success factors, but new unconventional management decisions, an energetic wish of the territory to formulate clearly its strategical interests in the country, in the region and in the world. This is the aim of the territorial branding. Currently the changing of territory development paradigm takes place. It becomes the subject of socio-economic relations, goods, intangible assets concentration. The emphasis of the development shifts towards culture, entertainment, impressions.


An effect of various environmental properties on pedestrian walking speed was investigated. In two experiments participants were asked to walk inside the city along tracks, which consisted of streets with various amounts of vegetation and various degrees of traffic intensity. The walking speed was measured in eight selected sections. The data showed that pedestrians tend to speed up in environments without greenery, with a busy traffic and a high noise level. Moreover, walkers also tend to speed up in spaces, which are characterized by a lack of visual openness. Practical applications are discussed. Key-Words: Walking speed, Pedestrians, Landscape urbanism


Based on crystalline plasticity slip and strain hardening model, a rate-independent polycrystalline plasticity model was developed and introduced into finite element method. A "successive integration method" was firstly applied to the calculation of the plastic strain in large deformation analysis. By this method, it is easily to distinguish different resolved shear stresses and shear strain rate in different slip systems. The orientation distribution function is discretized by normal distribution function, and every FE integration points represent one crystal. Flanging earing tendencies with different initial orientations were discussed and verified by experiments. {123}634 texture can lead to earing at 45° direction, while the {100}001 texture at 0° and 90° directions. For the annealing aluminum sheet, the flange earing tendency is not obvious due to the balance between two main textures.


We provide some statements equivalent in ZFC to GCH, and also to GCH above a given cardinal. These statements express the validity of the notions of replete and well-replete car- dinals, which are introduced and proved to be specially relevant to the study of cardinal exponentiation. As a byproduct, a structure theorem for linear orderings is proved to be equivalent to GCH: for every linear ordering L, at least one of L and its converse is universal for the smaller well-orderings.


Subantimicrobial dose doxycycline (SDD) – 20 mg doxycycline, downregulates the activity of matrix metalloprotei− nases (MMPs) – the key destructive enzymes in periodontal disease. In 1998 FDA (Food and Drug Administation) approved Periostat® (20 mg doxycycline twice daily for at least 3 months) as an adjunct to scaling and root planning (SRP) in treatment of chronic periodontitis. The authors showed the most important events that led to the develop− ment of SDD as adjunctive treatment for periodontitis. They also reviewed the clinical, microbiological and safety da− ta relating to the use of SDD in patients with periodontitis. Studies have demonstrated the clinical benefits of SDD, when prescribed as an adjunct to scaling and root planning (SRP), in treatment of chronic periodontitis. The frequen− cy of adverse events during treatment with SDD does not differ significantly from placebo. SDD does not lead to the development of resistant strains and does not result in antibacterial effects (Dent. Med. Probl. 2009, 46, 4, 470–476).


2013 is already halfway over, and primary care physicians in many states have yet to receive increased Medicaid reimbursements that were supposed to take effect on Jan. 1 of this year. Now, it appears that some states won't begin getting those larger Medicaid payments to physicians until December.


Background Previous studies indicate ethnic difference in the risk of hypertension and diabetes in Uygur and Kazak adult populations. The current study aims at investigating if the similar ethnic difference exists in childhood and the influence of overweight on the ethnic difference in elevated blood pressure and fasting glucose. Methods A school-based survey was conducted in a random sample including 2142 Uygur (34.5%), 2078 Han (33.4%) and 1997 Kazak (32.1%) children and adolescents aged 7–18 years. Anthropometrics and blood pressure were measured by standard protocols and defined by the Chinese mainland national cutoffs. Fasting glucose were measured among 2295 subjects, randomly selected from the study population by ethnicity. The ethnic difference in mean fasting glucose, blood pressure were analyzed by gender by using general linear models by adjusting age, height and BMI. Multivariate logistic regression analyses were performed with or without adjusting weight status to evaluate the role of overweight on the ethnic difference in risk of EBP and hyperglycemia in the pediatric population. Results Overweight was more prevalent in Kazak children than Han and Uygur children (40.8% vs. 17.7% vs. 7.1%). Kazak children had lowest fasting glucose, whereas Hans had the highest levels of blood pressure and glucose, after adjustment of age, sex and BMI (as well as height for blood pressure only). Han children had the highest rate of elevated blood pressure followed by Kazak and Uygur children (30% vs. 25% vs. 8%, P < 0.001). Overweight was significant determinant to the risk of elevated blood pressure (OR = 1.33, 95%CI 1.23∼1.44), but did not affect the risk of impaired fasting glucose (OR = 1.19, 95%CI 0.86–1.65). Ugyur and Han had similar risk in IFG which is 9 times higher than that in Kazak children. The risk of elevated blood pressure differed among three groups, in the sequence of Han, Kazak and Uygur children (OR = 1.0, 0.67 and 0.47 respectively), and the difference remained when weight status was adjusted (OR = 1.0, 0.58 and 0.49, respectively). Conclusions The ethnic difference in the risk of high blood pressure and impaired fasting glucose, occur as early as in childhood, with Han children had the highest risks of both. The differences between Uygur and Kazak children match that reported in adult population. Overweight appears to have less effect on the risk of impaired fasting glucose than that on high blood pressure.

Research on families with disabled children describes how these families face many challenges in their daily lives; lack of information, practical and emotional stress, and struggles with the service system. Families from non-western countries are for various reasons seldom included in such studies, and there are few separate studies about families with "double" minority background. Thus we have little research based knowledge about ethnicity and disability, professionals, user organisations, and bureaucrats indicate severe challenges. They talk about language problems, culture differences, lack of information about the welfare system etc. International studies indicate that communication problems and poverty explain more than culture differences and religion. In this paper we will discuss how families with disabled children understand disability and how they cope with their situation. Do disabled people from ethnic minority groups face the same type of challenges as the majority population in their daily lives, or if they meet special barriers due to their minority status. Or do they meet special barriers due to factors as culture, religion, language, prejudice or racism? Do they have other or additional problems because of their status as ethnic minorities? What are their experiences from interaction with the service system?


The inductive output tube (IOT) is a high power vacuum tube amplifier popularly used in UHF television broadcasting. A small-signal nonlinear model is presented for the IOT. Several simplifying assumptions are made to make the proposed model more tractable mathematically. Component values are then assigned to this simplified model based on measured IOT S/sub 11/ performance. This model is used to predict IOT intermodulation performance for a unique test case. The results predicted by the proposed model compare favorably to the real world measured results for the same test case.


This paper presents the development and optimization of a solar simulator designed to irradiate uniform light on the target plane. A luminaire covering 3.6 $m$2was developed to simulate solar radiation on the device under test in a closed chamber free from the influence of external radiance. The apparatus uses metal halide lamps to match solar spectrum and performs electrical performance analysis in photovoltaic panels. The final shape of the luminaire structure was obtained running genetic algorithm and results presented a Class C solar simulator with non-uniformity equal to 9.9%. Comparisons were made between simulated and practical photovoltaic panels electrical characteristics resulting in a error less than 10%.

ABSTRACT This study is aimed at determining the factors influential in the acceptance of delivery drones as a new way for last-mile delivery in the future. In this regard, the study model was proposed using the UTAUT2 as the base model and adding the factors of psychological characteristics, perceived risk, and need for human interaction to it. The information about 357 Iranian buyers was collected for the PLS-SEM by designing an online questionnaire. The results indicated that all variables of UTAUT2, except for performance expectancy, had a positive and significant effect on the intention of buyers to use delivery drones. Moreover, the personal norm positively affected the users' intention, while the need for human interaction and perceived risk had adverse effects on it. The research findings indicated that innovativeness had a significant positive effect on effort expectancy and compatibility while having an insignificant effect on performance expectancy.


We present the results of H I line and radio continuum observations of five nearby E+A galaxies. These galaxies have spectra that are dominated by a young stellar component but lack the emission lines characteristic of significant ongoing star formation. They are selected from a unique sample of 21 E+A's identified by Zabludoff et al. in their spectroscopic search (published in 1996) for E+A galaxies using the Las Campanas Redshift Survey, in which over 11,000 nearby galaxies were examined. The five E+A galaxies span a range of environments: three are in the field, and two are in clusters. Only one system was detected in H I emission, the field E+A galaxy EA 1, with a total flux of 0.30 ± 0.02 Jy km s-1 and an H I mass of 3.5 ± 0.2 × 109 h-2 M⊙. The H I morphology and kinematics of EA 1 suggest a galaxy-galaxy interaction, with a dynamical age of ∼6 × 108 h-1 yr inferred from the H I tail lengths and velocities. This age estimate is consistent with the interpretation drawn from optical spectroscopy that starbursts in E+A galaxies began (and subsequently ended) within the last 109 yr. Our H I detection limits are such that if the other E+A's in our sample had the H I properties of EA 1, we would have detected (or marginally detected) them. We conclude that E+A galaxies have a range of H I properties. None of the galaxies were detected in radio continuum emission, with upper limits to the radio power of ∼1021 h-2 W Hz-1. Our limits exclude the possibility that these E+A's are dust-enshrouded massive starburst galaxies, but they are insufficient to exclude modest star formation rates of less than a few h-2 M⊙ yr-1.

Objective To investigate the expression of angiopoietin-related growth factor(AGF) in obese patients and its relationship with body mass index(BMI),waist circumference(WC),waist-hip ratio(WHR),blood glucose(FBG),plasma insulin(FINS) levels,and HOMA-insulin resistance index(HOMA-IR).Methods Plasma AGF levels were assayed by ELISA in 40 patients with obesity and 40 normal controls.The relationship of AGF level with BMI,WC,WHR,HbA1c,blood lipids,FBG,FINS,and HOMA-IR was also analyzed.Results AGF levels in patients with obesity were significantly increased compared with that in the control group([177.55 ± 74.09] ng/ml vs [122.37 ± 66.91] ng/ml,P 0.05).We also found that AGF level was positively correlated with Triglyceride(TG),FINS and HOMA-IR(r = 0.325,P 0.05;r = 0.451,P 0.01;r = 0.483,P 0.01);and was negatively correlated with high-density lipoprotein cholesterol(HDL,r =-0.529,P 0.01).Multiple regression analysis showed that HDL,BMI and FINS were the factors influencing AGF levels.Binomial Logistic regression analysis indicated that AGF level was positively correlated with obesity after adjusting sex,age,total cholesterol(TC),TG,HDL and low-density lipoprotein cholesterol(LDL)(OR 1).Conclusion The change of AGF level is associated with the metabolism disorder in obese patients,and it may also contribute to the pathogenesis of obesity.


In the forthcoming deployments of WebRTC systems, we speculate that high quality video conferencing will see wide adoption. It is currently being deployed on Google Chrome and Firefox web-browsers, meanwhile desktop and mobile clients are under development. Without a standardized signaling mechanism, service providers can enable various types of topologies; ranging from full-mesh to centralized video conferencing and everything in between. In this paper, we evaluate the performance of various topologies using endpoints implementing WebRTC. We specifically evaluate the performance of the congestion control currently implemented and deployed in these web-browser, Receive-side Real-Time Congestion Control (RRTCC). We use transport impairments like varying throughput, loss and delay, and varying amounts of cross-traffic to measure the performance. Our results show that RRTCC is performant when by itself, but starves when competing with TCP. When competing with selfsimilar media streams, the late-arriving flow temporarily starves the existing media flows.

Abstract The α-dicarbonylmonophenylhydrazones 1 and 8 do not react as simple ,,CH-acidic compounds" in the Mannich condensation reaction. In a concerted reaction with aminals in absolute dioxane they give rise to the products 5a-e and 10a-e with better practicability and much higher yields compared with the conventional method. The formal Mannich bases 5a/5b/5d and 10a/10b/10d with a cyclic amine part show in the dehydrogenation, using mercury- EDTA , a neighbouring group participation of the phenylhydrazono moiety yielding the corresponding lactams. With 5c only cyclization occurs leading to 1,2,4-triazine 19 in low yield, while 10c shows no dehydrogenation but an amine elimination to the vinyl-azo com pound 21 with consecutive cycloaddition leading to the 1,2-diazine 23.


Frequency agility is necessary for many applications of high-power microwave sources. To expand the frequency-tuning bandwidth of the backward-wave oscillator (BWO) with an extracting cavity while holding high efficiency and less amplitude fluctuation, a dual-mechanical tuning method by changing the drift length and the cavity length in synchronism is investigated in this paper. A bandwidth of about 750 MHz around 9.6 GHz with power efficiency of over 33% and amplitude fluctuation of about -1 dB is obtained. The total adjusted length is 24 mm. The simulation results demonstrated the frequency-tuning ability of the relativistic BWO with multigigawatt output power.

Ports are affected by climate change with broad implications for the development prospects of the global economy with substantial economic costs. Hence, it is necessary to ensure that maritime stakeholders understand the challenges posed by climate change on ports, and work together to develop appropriate adaptation measures for addressing this important issue. However, there are many uncertainties, given that the inter-dynamics between climate change and ports can significantly diversify in different geographical regions. Moreover, while the impact posed by climate change on ports is, undeniably, a type of risk, what exactly it is remains unclear and subject to diversified interpretations from different stakeholders. Understanding such, by using a fuzzy approach, this paper undertakes a quantitative analysis on the perception of different maritime stakeholders on the risks posed by climate change on ports. A risk analytical model is developed which simulates stakeholders' perception on the risks posed by climate change. The model is based on three attributes related to the potential threats posed by climate change on ports, namely timeframe, likelihood and severity of consequence. Its applicability is demonstrated using the data collected from a port in North America. By doing so, this paper greatly helps port planners and policymakers to develop effective adaptation strategies to climate change on ports. Meanwhile, the model can be used to prioritize critical impacts and evaluate the effectiveness of adaptation measures in terms of risk reduction.


Nowadays, the civil, business, and industrial electrical power loads in Indonesia are growth rapidly. The main growth is in non-linear load as source of current harmonic which causes serious problem in power quality and safety of electric power system. To solve the problem, power quality monitoring system which is integrated with more effective measurement, control, communication, and supervision ability are needed. To realize those, in this research paper, an online real-time current harmonic detecting and monitoring system using S transform based on LabVIEW software is designed and created. S-transform is chosen to give the support for operation in dynamic condition. Resulting prototype is a harmonic analyzer that works in single or three-phase line through the addition of two identical CT with CT-235. When this prototype is operated in linear or non-linear load, it can monitor the current harmonic in real time mode with continuous data update every 1 second and around 1% measurement error. The testing result also pointed out that prototype still gets to work when the load is changed dynamically. It is different with another harmonic analyzer based on Fourier transform (with analysis update every 10 cycles at frequency 50 Hz) which stops operating when dynamic frequency happened less than 10 cycles (0.2 second).

Whole genome profiling has greatly expanded our knowledge of the genes and genetic pathways associated with the development and progression of breast cancer [1–4]. As a result, numerous commercialized multigene prognostic and predictive tests have entered the complex and expanding landscape of breast cancer diagnostics (TABLE 1) [5]. These multigene predictors utilize a variety of test platforms including immunohistochemistry (IHC), FISH, quantitative real-time PCR (RT-PCR) and genomic microarrays and gene chips. Both decentralized reagent sales as diagnostic kits and centralized commercial laboratory assays are now available with integrated proprietary statistical data analysis tools and algorithms designed to calculate the test results [5–7].


In C. elegans, feeding is achieved through a well characterized behavior, pharyngeal pumping. This pumping is controlled by two pairs of pharyngeal motor neurons (MC and M3). Each pump cycle corresponds to the propagation of a single pharyngeal muscle action potential, initiated by MC and transmitted across a single cholinergic neuromuscular junction. The eat‐2 gene is required for nicotinic neurotransmission at the pharynx. We assessed pumping patterns exhibited by wild type (N2) and a series of eat‐2 mutant strains, each identified as possessing deficits in pumping, including: (Strain: genotype) DA465: eat‐2(ad465) II; DA1113: eat‐2(ad1113) II; DA1116: eat‐2(ad1116) II. We also assessed pumping patterns in N2 strain animals incubated in the anthelmintic and acetylcholine receptor antagonist Levamisole ((−)‐Tetramisole hydrochloride; 0 – 50 uM). All studies we done in animals incubated in 10mM serotonin in M9 buffer. We recorded electropharyngeograms (EPG) using the recently developed ScreenChip system (NemaMetrix) to detect individual pump events, and analyzed recordings using an algorithm (WormBeat) to distinguish and quantify neuromuscular fidelity of the pharynx and pharyngeal pumping pace variation. As expected, mutant strains and Levamisole‐exposed N2 worms each illustrated pump pattern defects. Results show that the WormBeat algorithm can identify subtle treatment effects and distinguish phenotypic variation between mutant strains. Pump pattern assessment distinguished individual strains and allowed comparison of defect to the Levamisole dose‐responses of N2s.


It is well known that the reinforcement of the Soil is considered as a solution to its stability problems. This technique ameliorates the mechanical and physical comportment of the soil. Based on this, this research paper aims at investigating the behaviour of a specific type of dried-cemented-sandy soil reinforced with discrete elements such as polypropylene fiber basically through experimental tests. The latter are a series of consolidated drained triaxial tests which were carried out on samples of sand that are prepared with 0, 3 and 6% of cement, reinforced with 1% of polypropylene fiber (12, 18 mm) randomly distributed. Furthermore, those contents are measured by the volume of dry sand. In addition to these tests, a parametric study has also been conducted on a road embankment using a finite element program such as Plaxis 2D in order to observe the variation of different parameters like safety factor and the displacements (Ut, Ux, Uy). The test results showed that the addition of cement and polypropylene fiber of different accommodations increased both cohesion and friction angle of sands while the numerical results indicated that the presence of these additions improved the safety factor and decreased significantly the displacements.


There's an intoxicating buzz to Japan's urban centres, with their vibrant street life, glowing streetscapes, 24-hour drinking and dining scenes, architectural wonders that redefine what buildings – and cities – should look like. Leave them behind and you've got a country that is more than two-thirds mountains, with bubbling hot springs at every turn. In the warmer months there is excellent hiking, through cedar groves and fields of wildflowers, up to soaring peaks and ancient shrines (the latter founded by wandering ascetics). In the winter, all this is covered with snow and the skiing is world class. (And if you've never paired hiking or skiing with soaking in an onsen, you don't know what you've been missing.)


In this paper, the effect of biaxial strain on the mobility of single-layer transition metal dichalcogenides (MoS 2 , MoSe 2 , WS 2 , WSe 2 ) is investigated by accounting for the scattering from intrinsic phonon modes, remote phonons, and charged impurities. Ab-initio simulations are employed to study strain induced effect on the electronic bandstructure and the linearized Boltzmann transport equation is used to evaluate the low-field mobility. The results indicate that tensile strain increases the mobility. In particular, a significant increase in the mobility of single layer MoSe 2 and WSe 2 with a relatively small tensile strain is observed. Under compressive strain, however, the mobility exhibits a non-monotonic behavior. With a relatively small compressive strain the mobility decreases and then it partially recovers with further increase in compressive strain


The invention relates to a herbicidal combination containing ametryn and diuron. The herbicidal combination contains the ametryn and the diuron as active ingredients, the total weight of the ametryn and the diuron is 10 to 30 parts by weight, wherein the weight ratio of the ametryn to the diuron is 1:1 to 5, the herbicidal combination also contains Beta-cyclodextrin and urea as adjuvants, the total weight of the Beta-cyclodextrin and the urea is 5 to 10 parts, wherein the weight ratio of the Beta-cyclodextrin to the urea is 1 to 3:4. The herbicidal combination guarantees the synergism between the herbicides, and moreover, the time of weed control is shortened.

In this paper, we establish the linear independence of values of the $q$-analogue of the exponential function, $E_q(x)$ and its derivatives at specified algebraic arguments, when $q$ is a Pisot-Vijayraghavan number. We also deduce similar results for cognate functions, such as the Tschakaloff function and certain generalized $q$-series.

A homogeneous melting eutectic Au/Sn solder bump for laser chip application has been developed. The under‐bump metallization consists of a Ni wetting layer, a plating seed layer of Pt/Au/Ti multi‐layer scheme. The solder is electroplated as a sequence of Ni, Au and Sn layers. The bump can be exposed to multi‐step reflow cycles. The reflow of the solder as plated starts with a phase forming process in the solid state which results in an eutectic‐like phase and the near eutectic dand z phases. The dand z phases dissolve during the liquid state stage of the reflow at temperatures between 300 and 350 °C. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Nanomagnetic logic (NML) has attracted substantial attention during the last decade due to its promise of high energy efficiency combined with non-volatility. Information is transferred through antiferromagnetic dipole coupling in the chain of nanomagnetic dots [1]. To date, external magnetic field [2] and spin Hall effect [3] have been used for clocking, however, both methods have high energy dissipation (at least 100fJ per flipping). Here we demonstrate a new Bennett clocking scheme where the nanomagnetic dot with perpendicular anisotropy can be individually controlled by applying voltage to patterned electrodes. We build the fully coupled model for strain-mediated perpendicular Bennett clocking based on Ni and CoFeB system respectively and analytically show a four order of magnitude reduction in energy dissipation can be achieved using our system.


An improved method for the determination of fat-globule size distribution has been worked out and applied to samples of sow's milk drawn sequentially. The distribution patterns for the globule sizes of sow's milk have been determined. Globules range in size from less than ½μ to over 7μ. The maximum number of globules occurs at different sizes in different sows, the largest maximum size group so far recorded being 2–2·5μ, the smallest maximum group being 0–0·5μ. There is no marked trend in size with stage of milking, though usually the maximum size is less for later milkings if it changes. The strippings of sow's milk, unlike those of the cow, do not appear to be richer in fat than the earlier milk. Also unlike the cow, the globules of sow's milk do not cluster or clump (see Fig. 1). This explains the slow rate of creaming of sow's milk.


Blind nonlinear compensation for RF receiver is an important research topic in 5G mobile communication in which concurrent multi-band signals are employed to enable multi-access in heterogeneous networks. Since a nonlinear compensator processes intermodulation bandwidth of more than three times of signal bandwidth, reduction of power consumption is essential. This paper proposed a novel nonlinear compensation technique for receivers, which employs sub-Nyquist sampling A/D conversion. By folding outband spectrum, it achieves similar compensation performance while reducing the sampling speed of A/D converter to less than half of the normal sampling.

[ 14 ] Moreover, It has been demonstrated that [MoS 4 ] 2− and some other molybdenum sulfi de anions can be doped into PPy during the polymerization process, [ 15 ] which makes it an ideal carrier for MoS x . Herein, we demonstrate a simple way to fabricate polypyrrole/MoS x hybrid (PPy/MoS x ) fi lms by a one-step electrochemical copolymerization. The PPy/MoS x fi lms exhibit an outstanding HER performance that is comparable to that of commercial Pt/C catalysts. The highly active PPy/MoS x fi lms for HER were prepared in 0.1 M NaClO 4 containing 0.5 M pyrrole (Py) and 2 m M


As cognitive radio networks are conceptualized to make use of the opportunistic spectrum access, the users of these networks may face problems in satisfying their quality of service (QoS) requirements. Some services of users like real-time audio and video which cannot tolerate inter-packet delays will be affected more due to this. The problem occurs due to the non-availability of channels to these applications at some instants. This problem can be addressed if the available channels are judiciously distributed among the competing users. One such mechanism that dynamically allocates the competing users to multiple queues, and shifting the users to higher-level queues as the time elapses is introduced in this work. This is found to help the users of cognitive radio networks to communicate reasonably well even when fewer channels are available for opportunistic use. Results are indicated in terms of blocking probabilities of real-time data. Markov chain-based analysis and discrete event simulation studies are carried out.

The evolution of altruism is frequently studied using models of non-random assortment, including kin selection. In genetic kin selection models, under certain assumptions including additive costs and benefits, the criterion for altruism to invade a population is Hamilton's rule. Deviations from Hamilton's rule occur when vertical transmission has cultural and genetic components, or when costs and benefits are combined multiplicatively. Here, we include oblique and vertical cultural transmission and genetic transmission in four models—two forms of parent-to-offspring altruism, sibling-to-sibling altruism, and altruism between offspring that meet assortatively—under additive or multiplicative assumptions. Oblique transmission may be conformist (anti-conformist), where the probability that an individual acquires a more common cultural variant is greater (less) than its frequency. Inclusion of conformist or anti-conformist oblique transmission may reduce or increase the threshold for invasion by altruism relative to Hamilton's rule. Thresholds for invasion by altruism are lower with anti-conformity than with conformity, and lower or the same with additive rather than multiplicative fitness components. Invasion by an allele that increases the preference for altruism does not depend on oblique phenotypic transmission, and with sibling-to-sibling altruism, this allele's invasion threshold can be higher with additive rather than multiplicative fitnesses.

The influence of plasma, gas and salt-bath nitriding techniques on the friction coefficient of AISI 430 ferritic stainless steel was studied in this paper. Samples were plasma nitrided in 80 % N 2 + 20 % H 2 atmosphere at 450 °C and 520 °C for 8 h at a pressure of 2 mbar, gas nitrided in NH 3 and CO 2 atmosphere at 570 °C for 13 h and salt-bath nitrided in a cyanide-cyanate salt-bath at 570 °C for 1.5 h. Characterisation of nitrided layers on the ferritic stainless steel was carried out by means of microstructure, microhardness, surface roughness and friction coefficient measurements. Friction characteristics of the nitrided layers on the 430 steel were investigated using a ball-on-disc friction-wear tester with a WC-Co ball as the counter-body under dry sliding conditions. Analysis of wear tracks was carried out by scanning electron microscopy. Maximum hardness and maximum case depth were achieved on the plasma nitrided sample at 520 oC for 8 h. The plasma and salt-bath nitriding techniques significantly decreased the average surface roughness of the 430 ferritic stainless steel. The friction test results showed that the salt-bath nitrided layer had better friction-reducing ability than the other nitrided layers under dry sliding conditions. Furthermore, the friction characteristic of the plasma nitrided layer at 520 oC was better than that of the plasma nitrided layer at 450 °C. DOI: http://dx.doi.org/10.5755/j01.ms.19.1.3819


Employee stock ownership is the main way for state-controlled mixed-ownership enterprises to carry out medium and long-term incentives. The mixed-ownership corporate governance model provides convenient conditions for diversified shareholders to hold shares, and also lays a good foundation for the development of employee shareholding. The implementation of employee shareholding started earlier, and related policies have undergone multiple rounds of revision and improvement. This article sorts out the relevant policy context of employee stock ownership, and analyzes the current policy content to provide strong support for state-owned mixed-ownership enterprises to carry out employee


Patients with traumatic brain injury who fail to obey commands after sedation‐washout pose one of the most significant challenges for neurological prognostication. Reducing prognostic uncertainty will lead to more appropriate care decisions and ensure provision of limited rehabilitation resources to those most likely to benefit. Bedside markers of covert residual cognition, including speech comprehension, may reduce this uncertainty.


Abstract This study aimed to provide a brief historical overview of occupational medicine in Sibiu County combined with epidemiological evidence and trends in occupational diseases useful to design an agenda for future research and development of other components. Methods: to depict a model of circumstances, correlations, and trends, we applied to the local employee population a semi-structured narrative review method combined with the analysis of occupational diseases. The search strategy relied on literature and document review to create a timeline. We used a statistic chart histogram to highlight the most significant factors. Results: since 1950, concerning the industrial profile and the significant health effects on workers, we identified six stages of developing an occupational health network. The coverage was both for medical and hazard surveillance through a centralized system in the communist regime and recovery in the unique Sanatorium for occupational diseases established in the area. Occupational medicine private health services and the Faculty of Medicine from Sibiu appeared in the 1990s. Sibiu's occupational disease model was a particular one in the 20th century, given the burden of lead poisoning from local industries. Infectious diseases in medical staff related to sporadic epidemics and the ongoing COVID-19 pandemic as an emergent professional risk pose new current challenges for occupational medicine. Conclusion: unique challenges increase the need for occupational epidemiologic research and the need for advances in other components of occupational health, but lessons from the past and traditional methods are well documented and still valuable.


There is no doubt that malignant neoplasms produce a complex effect on a human organism. The general mechanisms of occurrence and tumor progression are intensively investigated and there has been obtained a significant material on molecular and clinical oncology which is used in close disciplines, such as dermatovenerology.


Energy-efficiency is one of the major concerns in wireless sensor networks since it impacts the network lifetime. In this paper, we investigate the relationship between sensor network performance, particularly its lifetime, and the number of active reporting nodes N by using both analytical and simulation approaches. We first demonstrate that decreasing the number of reporting nodes increases the number of reports that need to be sent to the sink, in order to achieve the desired information reliability regarding the detected event. On the other hand, we show that reducing the number of reporting nodes alleviates the energy wastage due to collisions. Based on this tradeoff, and as a main contribution, we derive the optimal number of reporting nodes Nopt.energy that minimizes the energy consumed to report reliably the occurrence of an event. In other words, we prove that limiting the reporting tasks of a detected event to a small subset of sensor nodes (i.e., Nopt.energy), instead of using all the sensor nodes in the event area, enables significant energy conservation.


Social tagging available in social media can potentially be integrated to build an effective online collaborative learning community. The purpose of this study is to understand the nature of social tagging for graduate students in an online learning program and how does their social tagging relate to building online collaborative learning communities and student engagement in distributed social bookmarking resources? The research questions are: how do students perceive building collaborative learning communities through social tagging in distributed learning resources? How do students build a collaborative learning community through social tagging in distributed learning resources? Mixed methods, survey, and tag analyses were utilised to collect the data from 44 online graduate students. This study concluded that the learners' social tagging nature is mainly using content tags rather than community-connected tags. Learners tagged to share with the general public to build communities of interests and passion, not with specific teammates or collaborators to build communities of purpose and practice. It suggests social tagging architecture as a social tagging literacy to support learners to build effective online collaborative learning communities.


Global Positioning System geodetic measurements at thirteen locations in Indonesia and four in Australia reveal that the Australian continent has accreted the Banda island arc to its margin. Small relative velocities of five sites on west Java, south Kalimantan, Bali, and south Sulawesi define a rigid Sunda shelf that moves relative to northern Australia in a manner consistent with pole locations from NUVEL-1 Australia-Eurasia but at a rate that is about 7% slower. Block-like northward motion of the southern Banda arc toward the Sunda shelf at nearly the same rate as Australia suggests that the Timor trough is now inactive as a thrust. Little of the convergence of Australia with Eurasia is accommodated by strain within the Banda arc structure. Most of the convergence appears to occur as northward translation of the rigid arc with shortening on the Flores and Wetar thrusts and possibly on faults within the back arc basin.

Determination of attitude or Euler angles is essential in monitor and control of the ight of aerial vehicles like aircraft, missiles, rockets, UAVs, and ying munitions. The paper considers a low-cost small-size sensor system consisting of a 3-axis MEMS accelerometers and a 3-axis AMR magnetometers. A computational algorithm is proposed to improve sensor system reliability. The iterative algorithm based on Newton-Raphson's search scheme computes the rotation angles in multiple ways using dierent subset of sensors. Simulations and real-time hardware-in-the-loop experiments are used to demonstrate how to detect the failed or contaminated sensors and how to determine the Euler angles using the healthy sensors.


This article discusses ways in which clinicians label, create, exacerbate and defuse situations called "crises." Several models of crisis work are described and illustrated with examples from cases. The author develops and advocates a social constructivist view of crises – to increase clinicians' flexibility and self-awareness, and reduce unintentional harm to clients.


10.30772/qjes.v10i4.494 Abstract: In the present study the applicability of hydrodesulfurization of a mixture of crude oil fractions (e.g., naphtha, kerosene, and gas oil ) in a single hydrotreating reactor packed with NiCoMo/Al2O3 under various operating parameters such as temperature (310-370 oC), pressure (40-55 bars), weight hour space velocity (1.2 to 3.6 h-1), and hydrogen-to- liquid hydrocarbon ratio (150-300 vol/vol). Experimental results showed that temperature and pressure have a positive effect on process performance while weight hour space velocity gives a different trend. The optimum value of (H2/Hydrocarbon) ratio was found experimentally to be 200 vol/vol after which the increase in this ratio reserved. reduction in HDS% because decrease in contact between H2 gas and Hydrocarbon in reactor. Results showed that the best conditions (350 oC, 50 bars, 1.2 h-1, and 200 vol/vol) in which gave the hydrotreating (HDS) efficiency of 95.8%.The results confirmed the applicability of the NiCoMo/Al2O3 catalyst for HDS reaction of a mixture of middle distillate (e.g., naphtha, kerosene, and gas oil). It was found that at higher pressure and temperature (i.e., T> 350 oC; P> 50 bars) a thermodynamic equilibrium was established. As observed, there is a 1.6% reduction in gas oil less than that of the conventional method. However, kerosene, heavy naphtha, and light naphtha undergo increases of 0.6%, 0.75%, and 2.75% respectively over these from conventional method. These results reveal that the quantity of fractions is almost the same for both methods. As it can be observed, that measured properties of the oil fractions produced by the proposed method are almost the same as those produced by conventional method. However, specific gravity (sp.gr) of the oil cuts produced by present study (i.e. sp.gr of kerosene, heavy naphtha, and light naphtha 0.785, 0.728, 0.655 respectively) is somewhat less than sp.gr of the same fractions produced by conventional methods (i.e. sp.gr of kerosene, heavy naphtha, and light naphtha 0.788, 0.738, 0.65 respectively), which gives a clear indication of properties improvement of these fractions. Experimental results confirmed the applicability of the proposed method for HDS of a mixture of Iraqi middle distillates (i.e., naphtha, kerosene, and gas oil) simultaneously in a single fixed bed at high activity and the sulfur reduce into less than 10 studied experimentally the influence of aromatics addition on the hydrotreating (HDT) of oil residue. Authors reported that the addition of aromatics enhanced the removal of heteroatoms and metals from oil investigated the effect of different feeds of crude oil (Arabian Light, Buzurgan, and Ural) on the reactions of hydrodesulfurization (HDS) and hydrodemetalization (HDM) under industrial conditions using commercial Authors reported that properties of the feed have pronounced effect on the HDT efficiency. CoNiMo catalysts with various content of promoters were used 2016) for hydrodesulfurization of gas oil. Temperature equal to 390 o C and pressure equal to 90 bars were used to investigate the optimum proportions of active metals in the catalyst. Abid et (2017) studied the influence of N- species on hydrodesulfurization activity of SRHN loaded with C4H4S compound, as a sulfidation agent, over CoMo/γ-Al 2 O 3 in a fixed bed reactor at variable operating parameters (e.g., T= 593- 653 K, P= 20-35bar, weigh hour space velocity = 2.5-5 h -1 , and (H 2 /oil) ratio = 60 vol/vol. with various concentrations of carbazole and Authors reported that conversion of sulfur increases as T and P increased. However the image of sulfur conversion with weight hour space velocity was Authors revealed that efficiency raised up in the following unreacted H 2 , NH 3 , and H 2 S) from liquid product which accumulated in a product tank and distillated in fractionation column to light naphtha, heavy naphtha, kerosene, and gas oil. The liquid feed and hydrogen gas were measured via calibrated digital flow meters installed on the feeding reserved. Regression analysis of experimental data generated Equation (2) which represents a polynomial related the objective function (i.e. %HDS) to the studied operating variables with correlation coefficient (R 2 ) = 0.9955; Adj.

Molecular dynamics simulations were performed to investigate the anisotropic hear transfer of single walled carbon nanotube systems. The Brenner potential with the simplified form was employed as the potential function between carbon and carbon within a nanotube. The axial thermal conductivity decreases when mixing C13 isotopes to a C12-SWNT either at random or in order. The heat transfer of an SWNT bundle in the radial direction was characterized by measuring the thermal conductance at the boundaries. The radial thermal conductance was found to be much lower than the axial one even with presence of some defects in the structure.


Previous models of visual search have hypothesized either a random search or a repeated systematic search strategy. Although both models reproduce well the cumulative search time distribution, F(t), neither fully accords with eye movement data. A new model is proposed in which search is intended to be systematic but suffers from imperfect memory. Systematic search is then a special case in which the memory is perfect, and random search a special case in which the memory is totally lacking. The model was derived for single and multiple occurrences of a single fault (or target) type. Where the model could be proved to be insoluble, a simulation model was used. Simulation results were compared with the previous calculations of Morawski, Drury, and Karwan (1980) and were shown to give identical results for pure random and pure systematic search. As the parameters of the memory model were varied, a family of curves between these extremes was produced.


The design and analysis of a miniaturised double-ridged horn antenna for active microwave imaging application are presented in this study. For such an application, a physically small horn is required. For effective signal penetration, a low frequency of operation (about 1.4 GHz) is selected. An array of these sensors is intended for use in a cylindrical breast imaging system, which is under development in the authors laboratory. The miniaturisation is achieved by loading the double-ridged horn antenna with distilled water (e r = 76), a high permittivity, but easily available material. Further size reduction is achieved by reducing the aperture size and flare length in the horn section. The frequency response and both near- and far-field patterns were studied. Two simplified prototypes were fabricated, and as per the system requirements, tested in a cylindrical container filled with distilled water. Measured and simulated reflection and transmission responses are discussed. Measured radiation patterns are compared with the simulated ones to validate the analysis.


SUMMARY Mineral factors are important in optimizing growth media for production of high quality biocontrol agents. In this work we investigated the effect of some minerals and some combinations of them during fermentation of Pseudomonas fluorescens UTPF61 on its growth in flask and fermentor and its subsequent antagonistic activity in vitro and in planta. Its survival during the formulation process and shelf life over a period of 60 days was investigated. None of the mineral amendments had an effect on bacterial growth. In dual culture assays bacteria grown in a zinc-supplemented medium, showed the maximum inhibition (20 mm) of mycelial growth of Sclerotinia sclerotiorum. Medium including a combination of zinc, bromine and iron gave maximum inhibition of mycelial growth. In greenhouse studies, bacteria grown in medium with zinc showed high inhibition against S. scletoriorum. Cobalt, magnesium and copper had a negative effect on antagonistic activity. Bacteria obtained from medium including a combination of zinc and molybdenum showed high antagonistic activity and resulted in 55% healthy plants. A combination of Zn-FeMo improved resistance of the bacterial cells to the drying process. In all treatments (in both flask culture and fermentor studies) UTPF61 survived up to 60 days without any dramatic decline from the initial population.

It is also a well known fact that the kinetics of gaseous reduction of Fe203 to Fe is faster


The purpose of this study was to utilize it as a basic data for local self-government in each region to plan and perform the oral health program targeting children and mothers as guardian. Data had been obtained by using children's oral examination and mothers' self-reported questionnaire method from June 1 to June 30 in 2007 targeting kindergartens where are located in the region of Hwaseong city. The survey was conducted targeting totally 239 people. Its results are as follows. 1. The healthy-tooth rate in the whole children accounted for 79.12%, thus girls were indicated to be a little higher with 80.36% than boys with 78.13%. Carious-tooth rate showed 8.74% for boys and 6.07% for girls. The dentalcaries experience treatment rate showed 11.37% for boys and 12.59% for girls. 2. The index of children at age 5, df rate was 39.3% in the whole, thereby having been indicated that boys with 41.3% are higher than girls with 37.2%. Even dft index is showing the higher index in boys with 3.9 than girls with 3.2. 3. As a result of examining mothers' oral-health behavior, mothers with out employment thought the self oral-health state to be good(p = 0.002). In appearance of scaling experience or of periodic dental checkup, a slight difference is being shown according to general characteristics, but wasn't significant. 4. As a result of examining children's oral management, it was indicated that the higher economic level(p = 0.011) and the more in mothers without employment lead to giving a light meal less(p = 0.41). In appearance of children's periodic dental checkup, the higher academic background level(p = 0.047) and the more employment(p = 0.044) led to receiving dental examination.


1. Abstract A simulation analysis of a new method to identify a raw coal separation process to produce concentrate, middle product and refuse is presented in the paper. The washability characteristic of a raw coal, the partition curve of a gravitational separator and separation densities have been identified. The washability characteristic determines the yield and ash content (or other quality attribute) of elementary density fractions in a given size fraction of a raw coal. The partition curve of a separation machine (heavy media vessel or jig) determines the probability of elementary fraction flow to concentrate, middle product or refuse. This probability is the function of density and size of elementary fraction and the separation density of the machine (heavy media density or a set point in the refuse removal controller in the case of jigs). On-line identification is performed with the use of a soft monitoring system consisting of belt scales for tonnage measurements of products, on-line radiometric ash monitors and software interpreting these measurements. The signals from monitoring system create a vector determining properties of products. These signals are compared to the respective signals generated in the on-line simulator working in parallel with the identified system. Sets of washability characteristics, partition curves and separation densities are automatically generated in the on-line simulator. They create a vector which determines the simulated properties of the three products. The best set of generated values is chosen on the basis of the minimum "distance" between the two vectors according to the accepted criterion. The search for the minimum distance of those two vectors is performed with the use of a genetic algorithm. The method has been tested using a simulation model for the three-product coal separation process in a jig.


General purpose Problem Solving Environments (PSEs) like Matlab are widely used in the fields of science for development of new algorithms. If a lot of computing power is required to run these algorithms, today's PSEs lack support for accessing the distributed infrastructures of the organisation (i.e. grids), which limits the size of the problems that can be solved. This contribution shows a new approach to utilize the grid from within PSEs without major adjustments by the user. The primary tools are GridSolve and and the grid-middleware gLite. The applicability is illustrated by an exemplary algorithm (Mandelbrot calculations).
