The interaction of a laminar flame with its self-generated boundary layer in a rectangular channel was numerically simulated using the two-dimensional, reacting, Navier-Stokes equations. A two species chemistry model was implemented which simulates the stoichiometric reaction of acetylene and air. Calculations were performed to investigate the effects of altering the boundary condition of the wall temperature, the Lewis number, the dynamic viscosity, and the ignition method. The purpose of this study was to examine the fundamental physics of the formation of the boundary layer and the interaction of the flame as it propagates into the boundary layer that its own motion has created.

ECOWAS has made some glaring and commendable strides in the subregion. Apart from economic integration and free movement of its member states, it has pacified the political turbulence in Liberia and Sierra Leone in the aftermath of the Cold War, and created a fertile political ground for democracy to flourish in both countries. However, questions are being asked as to whether the new instabilities that have engulfed the region in the locations of Togo, Mauritania, Mali, Niger and Guinea Bissau are propelling the region back to the path of the 'bad old days'. In response, this paper seeks to analyse whether ECOWAS possesses sufficient arrows in its quiver and enough political will to confront the new complex political challenges. Borrowing Jungian psychological expression, the author asserts that the subregion is threading the part of political 'individuation', and reminds readers that it took Europe more than two centuries to attain political equilibrium.
A peep into the dusty cellars of historical archives will inform us that Africa had been treated to the gory episodes of assault to its democratic structures occasioned by frequent military coups. The incursion of the military into politics had in turn dwarfed the region's incremental gains in terms of democratic dividends.


ABSTRACT This study examined the associations between a large set of health indicators and wellbeing among older people (aged 66 or more years) in Sweden. The data were drawn from the Swedish Panel Survey of Ageing and the Elderly (PSAE), with variables covering information about health, daily activities, social interaction, anxieties and worries, and economic hardship. A series of confirmative factor analyses were used to reveal if and how indicators of living conditions could be subdivided into latent factors, and several socio-economic and socio-demographic variables were used as their predictors. Differences between men and women and between a number of age groups of old people were systematically scrutinised. The preferred representation of the data was a nested model that identified one global factor, which related to all manifest indicators, and three residual factors that measured the specific experiences of physical impairment, psychosocial distress and economic difficulties. The findings improve our understanding of the relationships between indicators of health and wellbeing and the various latent dimensions that simultaneously affect response patterns. More importantly, they also facilitate our understanding of older people's wellbeing and assists the interpretation of single, commonly used indicators such as subjective health.


Draw bead geometry parameters have a significant effect to the quality of sheet metal forming. The application of response surface method (RSM), orthogonal experiment design method (OEDM) and dynamic explicit finite element method (FEM) in the optimum design (OD) for draw bead geometry parameters used in drawing procedure of cross member panel, a benchmark of Numisheet'2005, was discussed. The comparison between the OD results and the draw bead geometry parameters offered by the benchmark was carried. The effectiveness of this method was verified.


OBJECTIVE: TO provide a comprehensive review of warfarin use in infants and children, including recommendations for appropriate dosage and monitoring parameters. DATA SOURCES: A MEDLINE search (1966-1995) was used to identify pertinent English-language articles in the medical literature. The key search term was warfarin. Additional material was obtained from references cited in articles retrieved through MEDLINE. STUDY SELECTION: All articles involving children younger than 18 years were evaluated. In addition, articles on the pharmacokinetics and pharmacodynamics in adults, adverse effects, and drug interactions were included. DATA EXTRACTION: Material selected for review included clinical trials, case reports, and surveys of practice. DATA SYNTHESIS: Warfarin has been used as prophylactic therapy in children with prosthetic cardiac valves as well as for prevention of thromboembolic complications associated with autoimmune disorders and protein C or protein S deficiency. Warfarin also has been used to prevent embolization in children with deep-vein thrombosis or clots in central venous catheters. According to the literature, an initial dosage of 0.1 mg/kg/d should provide anticoagulation without significant adverse effects. As in adults, dosing should be adjusted to achieve a target international normalized ratio (INR). Although the target range in children is not well established, INR values of 1.5–3 are recommended for most patients. Higher values have been used in children with prosthetic cardiac valves and hereditary clotting disorders. CONCLUSIONS: Due to its infrequent use, there is limited information on the effects of warfarin in children. Basic guidelines for initiating and monitoring warfarin were developed by using data gathered from clinical trials, retrospective reviews, case series, and surveys of practice.


Technological development in education should be balanced with digital competencies to create optimal education. This development has increased during the pandemic, which requires teachers to master digital competence to organize education for students. This study aims to determine the digital competence of science teachers and investigate differences in gender, length of work, and school levels of teaching. This study employed a cross-sectional survey and involved 105 science teachers in West Java Province, Indonesia. Online questionnaires were used to collect the data. This research has revealed that science teachers have different digital competence at the school level. In contrast, they do not have divergent digital competence regarding gender and length of work. Teachers with good digital competence can develop collaborative learning.

Defining of the tax impact on economic growth is of particular importance in the face of exacerbation of socio-economic, technological, environmental and other problems. Property taxes, as ones that have less distorting impact on taxpayers' economic behavior, compared to the greater part of the rest of the known taxes, are attracting more and more attention of many researchers and are considered from the standpoint of a potential fiscal policy instrument in ensuring positive dynamics of economic development. The purpose of the article is to summarize modern approaches and research results on the impact of the real estate tax on economic growth in order to identify opportunities for implementation of this tax instruments to stimulate economic development. It has been established that foreign researchers are studying the impact of taxes on real estate from the standpoint of distorting the distribution of resources in the economy, changing the decisions of economic agents on investment issues, growth rates of the housing stock, leveling income inequality, increasing the stability of tax systems to external shocks, etc. It was revealed that most authors consider the real estate tax as one of the most non-distorting, which, with a properly designed taxation mechanism, has practically no negative impact on economic activity, and therefore little hinders economic growth, helping to reduce income inequality, increase employment and income, efficient use of land. As a local tax, it is most often seen in terms of financing local budgets and is a useful tool for raising revenues and managing public finances, since raising effective rates and broadening the property tax base can offset cuts in other taxes that are more distortive of economic behavior. In Ukraine, the attention of the authors is focused on increasing the role of property taxes in providing income to local jurisdictions and strengthening their financial stability. There is a significant lack of national researches on the impact of real estate tax on economic growth in Ukraine. Further research on the functioning of the real estate tax in the new conditions of changing paradigms of economic development and international relations, and on the impact of the real estate tax on economic growth in Ukraine could reveal new aspects of its use in the national tax system.

The saxifrage family consists of mostly perennial herbs with simple, palmately veined leaves— mainly basal but sometimes arranged alternately on the stem—with panicles of small flowers usually on a separate stalk. Flowers almost always have 5 separate petals, 5 sepals, and 5 or 10 stamens. The ovary usually has 2 carpels and pistils and may be inferior, superior, or in-between and can be a good field mark to distinguish similar species. The flower parts are attached to a cup (hypanthium) and may appear tube-like because of fused sepals. The numerous seeds are usually in a capsule. This large family favors cool climates and is well represented in the Cascades, especially in shady habitats. It would be difficult to find a stretch of forest without at least a few representatives of Saxifragaceae. The latin name Saxifraga means "rock breaking" and there are quite a few rock lovers as well. Many species make good garden plants. Non-native species commonly cultivated include Bergenia, Astilbe, and Coralbells (Heuchera sanguinea). Two related families, Grossulariaceae and Parnassiaceae, were formerly included in Saxifragaceae.


It has now become evident that the transformation of matter into radiation taking place throughout the universe and the red-shift observed in the light from the extra-galactic nebulae appear to imply a non-static quality in the universe which can be treated with some success with the help of a non-static cosmological line element.(1) If the quantity which gives the dependence of this non-static line element on the time is set equal to a constant, if is found that the line element then becomes the same as Einstein's original line element for a static universe. Hence the Einstein static universe may be regarded as a special case of the more general non-static universe, and we must continue to be interested in the properties of the Einstein universe not only because it is a limiting case of the more general model for the universe, but also because it represents a situation which might arise in the course of the evolution of the actual universe. The present article will deal with the thermodynamics of the Einstein universe, and in particular will treat the conditions for thermodynamic equilibrium between matter and radiation in such a universe assuming the possibility of their transformation into each other.


Objective To study the ultrastructure of larynx lymphatic capillaries and the pathway of lymph formation of larynx in rabbit.Methods The light microscope and transmission electron microscope and computer image analysis system were used.Results There were three types of connection forms between endothelial cells of lymphatic cepillaries including end-end(24.26%),overlapping(49.26%)and interdigitating(26.48%) junctions,among which the opening condition was 2.94% and special junctional complexes in the interendothelial contact were 22.41%.Abundant vesicles were observed in endothelial cells of larynx lymph vessels,the numerical density and volume density and average diameter of the vesicles were135.59±2.68/μm3,0.0595±0.0040,76.46±2.64 nm.Conclusion The intercellular pathway might be the main pathway of the lymph formation in larynx,the vesicles transportation might play a little role in the lymph formation of larynx.


There are many processes involved in construction, it is necessary to optimize the path planning of construction robots. Most researches focused more on optimization algorithms, but less on comparative analysis based on the advantages and shortcomings of these algorithms. Therefore, the innovation of this paper is to analyze three advanced optimization algorithms (genetic algorithm, hybrid particle swarm algorithm and ant colony algorithm) and discuss how these algorithms can improve the optimization performance by adjusting parameters. Finally, the three algorithms are compared and analyzed to find an optimization algorithm that is suitable for path planning optimization of construction robots. The purpose of the optimization is to obtain the maximum benefit with the least cost and complete project in an efficient and economical way.


In this paper, we present a late summer (August–September) temperature reconstruction over the period 1792–2020 based on a tree-ring maximum latewood density (MXD) chronology for the southern Tibetan Plateau (TP). The reconstruction explained 66.2% of the variance in the instrumental temperature records during the calibration period 1960–2020, and captured the warming trend since the 1960s, which would support the current warming on the TP. In addition, a warming hiatus existed during 2001–2012 and the last 20 years (2000–2020) were the warmest period in the past two centuries. The reconstruction matched other MXD- and mean latewood density (LWD)-based late summer temperature reconstructions from neighboring regions, and fluctuated in synchrony with the Climatic Research Unit (CRU) Northern Hemisphere land surface temperature during 1850–2020. Multitaper method analysis and wavelet analysis revealed the significant periodicities of 2–3 years, 20–30 years, and 40–60 years in the reconstructed series. Our reconstructed series was very consistent and highly correlated with the Atlantic Multidecadal Oscillation (AMO). During the warm phase of the AMO, higher pressure and divergent horizontal winds over the TP contributing to warmer summers in the region. In addition, we found that the southern TP experienced the lowest temperature and downward solar radiation in the second year following large volcanic eruptions. The decrease in downward solar radiation may be directly responsible for the occurrence of lowest temperature. The results indicate that the AMO and large volcanic eruptions were impacting factors on temperature in our study area.


Unequal participation in certain types of political engagement creates unequal influence on political and civil matters (Boulianne, 2022). Studies find that men and women tend to do a similar amount of political participation, with women engaging in more private and flexible forms, and men participating in more direct and collective forms (Bode, 2017; Coffé & Bolzendahl, 2010; Van Duyn et al., 2019; Pfanzelt & Spies, 2019). However, more data is needed when considering Canadian trends, especially when it comes to the causes of these trends. In this study, I conduct statistical analysis of secondary data from a February 2021 Canadian survey (n=1,568) designed by Dr. Shelley Boulianne. I determine which forms of political participation have gendered participation gaps and whether or not these are related to conflict avoidance tendencies and having political female role models. I find few gender differences in political participation.  Some small gender differences persist in online forms of political participation, such as signing petitions online and commenting on news sites. Men were more likely post comments on news sites, compared to women; women more likely to sign online petitions, compared to men. As such, political participation moves online, the gender gap may be reproducing itself in online spaces.


The objective of this study was to determine if the Superpave high-temperature properties of polymer-modified asphalt binders correlate to asphalt mixture rutting resistance. An emphasis was placed on evaluating the rutting resistances of mixtures containing polymer-modified asphalt binders with identical (or close) performance grades (PGs), but varied polymer chemistries. This would indicate what types of modification provide properties that are, or are not, correctly captured by the current Superpave asphalt binder specification. Eleven asphalt binders were obtained for this study: two unmodified asphalt binders, an air-blown asphalt binder, and eight polymer-modified asphalt binders. Five binders used in a prior study were also tested. Asphalt binder properties were measured by a dynamic shear rheometer. Mixture rutting resistance was measured by: (1) G* and G*/sin(delta) from the Superpave Shear Tester (SST) frequency sweep at constant height, (2) cumulative permanent shear strain from the SST repeated shear at constant height (RSCH), (3) French Pavement Rutting Tester (French PRT), and (4) the Hamburg Wheel-Tracking Device. Cumulative permanent shear strain and the French PRT were the primary tests because they were specifically developed to measure rutting resistance. The high-temperature properties of the 11 asphalt binders had a high correlation to mixture rutting resistance as measured by the cumulative permanent shear strains. A weak correlation was found using the French PRT. Both correlations were high when analyzing the data from all 16 asphalt binders. A change in high-temperature PG from 70 to 76 significantly increased rutting resistance based on both tests. The main objective of this study was to determine which asphalt binders provide high-temperature properties that do not agree with mixture rutting resistance. In general, the number of discrepancies was low. It is recommended that the asphalt binders be tested using other aggregate types or gradations.

In the past ten years, the Vehicular Ad Hoc Networks (VANET) has been widely incorporated into intelligent transportation systems (ITS) and advanced assisted driving (ADAS), effectively promoting traffic management and autonomous driving Application development. Reasonable deployment of Roadside Units (RSUs) can greatly improve the performance and efficiency of VANET, which becomes a key issue. This paper proposes a multi-objective RSUs optimization model, which also considers the three optimization objectives of RSUs deployment cost, communication delay and coverage area, and uses the NSGA-II algorithm to solve the Pareto optimal solution set of the problem. Finally, the method in this paper is verified by a numerical simulation of the urban street RSUs deployment problem.


According to the Braun-Blanquet approach the segetal communities of rice agrocenoses of Eurasia belong to the class Oryzetea sativae Miyawaki 1960, although there is a lot of species that are diagnostic of different classes — Phragmito-Magnocaricetea Klika in Klika et Novák 1941, Lemnetea O. de Bolòs et Masclans 1955, Potamogetonetea Klika in Klika et Novák 1941, Bidentetea Tx. et al. ex von Rochow 1951, etc. The largest number of the described basic syntaxa (associations, subassociations or communities) are allocated in Eastern, South-Eastern and Central Asia. Lots of new syntaxa specific to the rice fields were described in Japan (Miyawaki, 1960), Southern Thailand (Nowak et al., 2015), Central Nepal (Nowak et al., 2016), North Korea (Kolbek et al., 1996; Kolbek, Jarolímek, 2013), Tajikistan (Nowak et al., 2013), Vietnam and the Philippines (Fried et al., 2017, 2018), many of which have been assigned in the alliance Ludwigion hyssopifolio-octovalvis A. Nowak, S. Nowak, Nobis 2015, the order Cypero–Echinochloetalia oryzoidis O. de Bolòs et Masclans 1955, the class Oryzetea sativae. The rice communities described in Western (Spain, Portugal, Andorra, Italy, France, Hungary, Romania, Bulgaria) and Eastern (Ukraine, Russian Federation) Europe which differ in species composition from those in Asian regions are assigned to the alliance Oryzo sativae–Echinochloion oryzoidis O. de Bolòs et Masclans 1955 within the above order and class.

The paper represents the first results of the classification based on 20 relevés of rice communities studied in 2018 in the Gudermessky and Shelkovskoy districts of the Chechen Republic, located on the northern slope of the Great Caucasian Ridge, the Chechen Plain and the Terek–Kuma Lowland. The areas under rice crop rotation are kept at an altitude of 20–35 m above sea level both in the north and in the plain part, mainly in the interfluves of the Terek and Sunzha rivers. The climate in the rice-growing areas is continental, insufficiently humid, with the very warm summers and moderately mild winters and the lot of heat and dryness in the summer months. The mean year temperature is 10.8 °C, during the growing season of rice (May–September) — 20.8 °C; the sum of effective temperatures above 15 °C is about 3100–3400 °C (Tulyakova, 1973; Ryzhykov et al., 1991); the annual amount of precipitation is 400—450 mm with less than 270 mm in summers. The largest areas on the Terek and Sunzha river interfluve are occupied by intrazonal meadow and swamp vegetation.

There are two associations and one community belonging to the alliannce Oryzo sativae–Echinochloion oryzoidis have been established within study area. The associations Echinochloo–Oryzetum sativae Soó ex Ubrizsy 1948 (Table 2, rel. 1–8) and Oryzo–Cyperetum difformis Koch 1954 (Table 2, exp. 9–14) are widely distributed in rice fields in Western and Eastern Europe, while the community Setaria pumila–Oryza sativa (Table, rel. 15–20) is a new one. On cultivated lands, the composition and structure of segetal communities depends on the intensity of agrotechnical measures, as well as on the depth and duration of flooding. The species diversity of the communities adjacent to the fields, formed in the discharge channels and on the dams between rice bays, have a significant impact. In the rice fields in the presence of chemical and agrotechnical processing, communities of the ass. Echinochloo–Oryzetum sativae prevail, and the communities of the ass. Oryzo–Cyperetum difformis and Setaria pumila–Oryza sativa are formed where this impact is not strong. The significant participation of Cyperus glomeratus is a distinctive feature of the Chechen Republic segetal communities from the analogous ones compare with the other regions of Europe.


To the Editor: We read with interest the recent report by Mukhopadhyay and Aubry1 regarding the recurrent primary synovial sarcoma of the chest wall. We agree with their conclusion that this rare neoplasm can behave aggressively and should be considered in the differential diagnosis of chest masses, especially in young or middle-aged adults.1 However, we cannot completely accept their evaluation that the synovial sarcoma reported was derived from chest wall. We also previously experienced a case of recurrent metastatic synovial sarcoma. In our patient, the sarcoma recurred only in visceral and parietal pleura several times and was surgically resected each time. Mukhopadhyay and Aubry reported that imaging revealed extensive pleural masses.1 At autopsy, the tumor encased the entire left lung in a ring-like fashion and mimicked the growth pattern of a mesothelioma.1 As the authors described, most synovial sarcoma occurs in the extremities, and synovial sarcoma of the thorax is rare.2–4 We would appreciate hearing from the authors how they confirmed that the sarcoma originated from chest wall. We would like to know what tissue of the chest wall was the origin of the tumor. Why did the sarcoma develop only in the thoracic space? Why did the sarcoma diffusely involve only intrathoracic organs and not cause destruction of ribs and the thoracic cage? Why did it not invade the chest wall?

DAEHLER, MARVIN W., and BUKATKO, DANUTA. Discrimination Learning in Two-Year-Olds. CHILD DEVELOPMENT, 1974, 45, 378-382. A series of 5 2-choice discrimination-learning problems was given to 48 2-year-olds to assess learning in this age group. For some children the positive instance on each problem belonged to a common category, while for others no conceptual relationship existed among the stimuli on succeeding problems. Subjects committed remarkably few errors, averaging only slightly over 1 error per problem. Children over 30 months of age did better than younger children, and girls learned faster than boys after the first problem. Presence of a category relationship among positive instances was not significantly related to learning, perhaps because discriminations could be acquired so rapidly.


A pulsed tunable laser Raman spectrometer is described. The relevant characteristics are: tunability in the range of 355–755 nm, peak power of > 100 kW, pulse duration 3.2 ns, spectral line width  10 ns while Raman spectra can be recorded with an experimental slit width > 0.5 cm−1. The overall performance of the instrument may be compared to that of a conventional cw laser Raman spectrometer having typical power levels of 100 mW. Spectroscopic measurements are discussed which demonstrate the capability of the apparatus to probe Raman processes which occur at the pico and microsecond time scale.


Aims: The aim of this study was to explore important factors that promote the best possible health for mother and child during pregnancy, birth and post-birth in an alternative birth clinic (ABC) in Norway.

Design: The authors used in-depth interviews to identify factors important in ABCs according to the holistic treatment model in the philosophy of ABCs.

Methods: Transcription and text condensation were achieved by looking for text to find themes and subthemes to explore daily activities and the role of empowerment.

Results: The most important factors were teaching women how to cope, mentally and practically, and being true to the philosophy of ABCs. Factors connected to empowerment of the women were strengthening their ability to make good decisions, their ability to cope practically, and the midwives' ability to step back and let the women gradually take responsibility.

Conclusions: The ABC in this study reflected theoretical principles for ABCs. Midwives shared common opinions of important factors empowering women.


Although intellectual property is just a sidelight of Roger Blair's work, he has published at least seven articles and coauthored a book on this subject. Blair's work sets out robust economic models that address nearly all of the significant economic issues in intellectual property. Moreover, by using the property rules framework, he has offered a useful counterweight to the reward-to-loss theory that dominates the literature.


The study of seawalls has been a subject for full scale (prototype) and laboratory testing dating back to before the start of this century.


An approach to printing of flat textiles is presented in this work. A screen-printing method was applied on a cotton fabric. An aqueous printing paste was prepared from thickening and crosslinking agents and an ultraviolet-sensitive tetrazole ring-based compound of 2,3,5-triphenyltetrazolium chloride or nitrotetrazolium blue chloride. After the printing process, a pattern was just visible with the naked eye. The development of colour occurred after exposure of the textile to ultraviolet light of 253.7 nm and was caused by the transformation of 2,3,5-triphenyltetrazolium chloride or nitrotetrazolium blue chloride salts into the corresponding formazans, which are insoluble in water. The printed designs were resistant to washing. The stability of the colour of the samples is discussed in the case of prolonged irradiation, both with ultraviolet light of 253.7 nm and with daylight. This method of printing is a recent proposition for creative textile designing. It also seems to indicate a likely type of dye that may be further developed as potentially attractive for ultraviolet-assisted printing or dyeing of textiles.


Cattle husbandry and grassland resource utilization in Imeko\Mon Local
government Area was studied for six months. The people involved in cattle husbandry
were found to be mostly Fulanis of Kwara -State origin who have settled in this area
for various length of time ranging from 1 to 20 years. The major breed of cattle being
reared is the white Fulani breed. That are mainly milk producers. The animals are sold
only in case of pressing financial challenges. Milking is carried out two times a day
with an average daily yield of 1.9 litre/milking. The animals are released into the
range in the morning. The range has patches of derived savanna interspersed with
thickets. There are no management practices on the range except rotational grazing
and annual burning deliberately carried out by the Fulanis themselves or by other that
are interested in games. Health management practices were poor. The cattle herdsmen
themselves carry out treatment of the animals, as veterinary services are not often
available in the study area.

An architecturally-inexpensive solution, which combines a standard truncated waveguide array and a single-layer patterned metasurface superstrate with wave manipulation capabilities, is proposed. A task-oriented formulation is adopted to mathematically formulate the EM associated multi-scale design problem, then solved with an innovative instance of the System-by-Design (SbD) paradigm where the fast and reliable modeling of the device is yielded by an ad-hoc artificial intelligence based surrogate. The final layout of the antenna array is validated with industry-standard full-wave numerical simulators.


Pratylenchus brachyurus stands out among the plant-parasitic nematodes that cause the most damage to soybean culture in Brazil. Thus, we investigated the interactions of different chemical groups in the seeds treatment for control of P. brachyurus. The experiments, carried out in a greenhouse, included eight treatments and six replicates in a completely randomized design. The chemical groups and interactions were: thiophanate-methyl; pyraclostrobin; fipronil; pyraclostrobin + thiophanate-methyl + fipronil and abamectin. The chemical interactions were: pyraclostrobin + thiophanate-methyl; thiophanate-methyl + fipronil; pyraclostrobin + fipronil. Seeds without product application were maintained as control. All combined products showed an antagonistic effect, however fipronil or when combined with thiophanate-methyl showed a pronounced efficacy in the control of P. brachyurus.

Conclusion: In order to further optimize scientific communication, meet the requirements set forth for the titles included in bibliometric databases of scientific citation, and improve the efficiency of the publisher and the editorial board, it is essential to update bibliometric indicators of the journal and expand the geography of authors and affiliated institutions, which will predetermine its future scientific growth and its comprehensive development.


The overall objective of the present paper is to review the role of V in microalloyed steels with a particular address as to how it affects microstructural evolution and mechanical properties. Its role in thermomechanical controlled processing (TMCP) is emphasised. The review is largely based on work carried out at the Swedish Institute for Metals Research (SIMR) during the last 25 years, but also includes reference to other relevant, published work. A specific aim is to demonstrate the present scientific knowledge of the subject. Therefore the understanding and interpretation of essential phenomena related to microstructure formation and properties are thoroughly examined, ranging from the influence of microalloying on prevention of austenite grain growth and recrystallisation, to precipitation in ferrite and its effect on strength. Within the well-known thermodynamic database, Thermocalc, a special microalloy database has been developed at SIMR, allowing reliable predictions of phase equilibria and thermodynamic functions for phase transformations in microalloyed steels. A comprehensive account is given of the role of V in the most important processing steps that the microalloyed steels are subjected to, viz. TMCP, continuous casting and welding. Compared to the other microalloying elements, Nb and Ti, V exhibits essential differences. In particular, the solubility of its carbonitrides is much larger and the solubility of its nitride is about 2 orders of magnitude smaller than its carbide, contrary to Nb but similar to Ti. For optimal alloy design and thermomechanical processing, proper allowance must be made for these differences. To reach the maximum ferrite grain refinement, ∼4 μm, repeated recrystallisation in a series of rolling reductions is used in TMCP of V-microalloyed steels, so-called Recrystallisation-Controlled-Rolling (RCR), as opposed to traditional controlled rolling of Nb-steels where heavy rolling at low temperatures in the non-recrystallisation regime is the means of attaining grain refinement. RCR presents some important advantages, in particular a more economical hot rolling practice by allowing low reheating and high finishing temperatures. As compared to Nb, V has certain further advantages as a microalloying element due to its greater solubility in austenite. The tendency for hot cracking of cast slabs is much less pronounced and dissolution of coarse V(C,N) compounds is more easily achieved prior to hot rolling than for the corresponding NbC. It is demonstrated that the relatively large solubility of V(C,N) and the much lower solubility of VN than VC makes V an eminent choice for strong and easily controllable precipitation strengthening. A corollary of the difference in VN and VC solubilities is that N becomes an essential microalloying element in V-steels, because it largely determines the density of V(C,N) precipitation and thereby the degree of precipitation strengthening. Moreover, since pure ferrite dissolves more N than C, the total N-content of the steel is normally dissolved in the ferrite before V(C,N) precipitation, whereas only a fraction of the C-content, given by the austenite/ferrite or ferrite/ cementite equilibrium, is dissolved in ferrite. Hence, by precise additions of N, this circumstance facilitates the control of V(C,N) precipitation strengthening.

This is one of the few unique books that explicitly explores what the common methodologies are across disciplines that stretch from the humanities to the exact sciences. The goal is to compare and contrast the modes of thinking and methods of research of diverse disciplines to allow readers to explore the common threads and distinct features of approach to research. Contributed by world-renowned authors, and written at a non-specialist level, it is accessible even to senior undergraduates and graduate students in various disciplines.


Technology commercialization needs a large amount of financial resources and governments in developed and developing countries play a critical role in resource allocation to the technology commercialization, especially through "Technology Development Funds (TDFs)". But, because of resource limitations, determining high priority technologies with higher impact on the country's innovative performance and the optimal resource allocation to technology development is very important for science and technology policymakers. "Technology portfolio planning" has been developed and applied in this regard. Accordingly, a two-phase decision-making framework has been proposed. At the first phase, the priorities of technology fields are determined by using the best-worst method (BWM) and at the second phase, a two-stage stochastic technology portfolio planning model is developed by considering technological projects' risks and export market, as one of the important factor in the "Global Innovation Index" (GII) ranking. It also has been considered technology fields' priorities, staged-financing, moratorium period, reinvestment strategy, and technology readiness levels (TRL) in allocating financial resources to technological projects The main advantages of our proposed model are considering uncertainty and early signaling about under performing technological projects Due to the uncertain nature of the problem, our solution methodology is based on the Sample Average Approximation (SAA). In order to demonstrate the applicability of this model, a real case study and its computational results are presented.


The diet of the bat Rhinolophus ferrumequinum was studied at the Zhi'an Village of Ji'an City in China, from June to August 2004. The bats were trained in a laboratory (volume: 9x4x4 m3). Foraging strategies of the bat were observed at night and prey remains were collected and identified. The results showed that the diet consisted mainly of Lepidoptera in summer, including 11 families, more than 30 species of moths, such as Noctuidae (36.6% by number), Sphingidae (24.1%), Geometridae (13.4%) and Limacodidae (9.5%). The length of culled wings ranged from 10–40 mm (97.7%). Pearson correlation analysis showed that the bat R. ferrumequinum foraged their prey selectively, but not opportunistically. From field studies, two ways were observed in which the bats retrieved their prey including aerial hawking during peak active period of the insects and flycatching during the insects' non-peak activity period. The bats never gleaned prey from the ground, though they appeared to be well able to detect fluttering moths on the ground.


This study investigated the English language competencies of students in rural primary
schools and the problems they faced in the process of learning Mathematics and Science
in English in the classrooms. Students and teachers from eight primary schools in the
districts of Batang Padang, Perak Tengah and Hilir Perak in the state of Perak were
involved in the study. Instruments included language tests, survey questionnaires and
interview checklists. Data analysis results produced several findings. Students generally
possessed better skills in listening and reading in English in Mathematics and Science.
They were weakest in speaking, followed by their writing skills. However, the biggest
problem was their overall mastery of the English language. As a result, there was a
tendency for teachers to use both Malay and English languages during classroom
instructions. There were also tendencies for students from better home language
background and higher socio-economic status to have better English language skills in
Mathematics and Science. Lastly, female students tended to be better in speaking and
reading in both Mathematics and Science subjects compared to male students. Male
students tended to be better in listening and writing compared to the female students.
However, analysis indicated no statistically significant difference in the language abilities
of students from both gender groups in learning Mathematics and Science in the
classroom.


Attitudes of 20 male and 5 female alcoholic patients toward treatment and treatment personnel were measured by the Semantic Differential at hospitalization and again at discharge. Attitudes toward nursing personnel tended to be less positive following hospitalization while attitudes toward self became more positive. The results are discussed in terms of treatment and its effectiveness.


This article generalizes our previous results [Le Maître. The number of topological generators for full groups of ergodic equivalence relations. Invent. Math. 198 (2014), 261–268] to the non-ergodic case by giving a formula relating the topological rank of the full group of an aperiodic probability-measure-preserving (pmp) equivalence relation to the cost of its ergodic components. Furthermore, we obtain examples of full groups that have a dense free subgroup whose rank is equal to the topological rank of the full group, using a Baire category argument. We then study the automatic continuity property for full groups of aperiodic equivalence relations, and find a connected metric for which they have the automatic continuity property. This allows us to provide an algebraic characterization of aperiodicity for pmp equivalence relations, namely the non-existence of homomorphisms from their full groups into totally disconnected separable groups. A simple proof of the extreme amenability of full groups of hyperfinite pmp equivalence relations is also given, generalizing a result of Giordano and Pestov to the non-ergodic case [Giordano and Pestov. Some extremely amenable groups related to operator algebras and ergodic theory. J. Inst. Math. Jussieu 6(2) (2007), 279–315, Theorem 5.7].


Owing to a growing number of attacks, the assessment of Industrial Control Systems (ICSs) has gained in importance. An integral part of an assessment is the creation of a detailed inventory of all connected devices, enabling vulnerability evaluations. For this purpose, scans of networks are crucial. Active scanning, which generates irregular traffic, is a method to get an overview of connected and active devices. Since such additional traffic may lead to an unexpected behavior of devices, active scanning methods should be avoided in critical infrastructure networks. In such cases, passive network monitoring offers an alternative, which is often used in conjunction with complex deep-packet inspection techniques. There are very few publications on lightweight passive scanning methodologies for industrial networks. In this paper, we propose a lightweight passive network monitoring technique using an efficient Media Access Control (MAC) address-based identification of industrial devices. Based on an incomplete set of known MAC address to device associations, the presented method can guess correct device and vendor information. Proving the feasibility of the method, an implementation is also introduced and evaluated regarding its efficiency. The feasibility of predicting a specific device/vendor combination is demonstrated by having similar devices in the database. In our ICS testbed, we reached a host discovery rate of 100% at an identification rate of more than 66%, outperforming the results of existing tools.

Abstract: Withstanding physical attacks in a hostile environment is of utmost importance for nowadays electronics. However, due to the long and costly development of integrated circuits (ICs), IC-level countermeasures are typically only included in varying degree and not in every chip of a device. Therefore, multiple-chip modules requiring higher levels of security are additionally protected against tampering by a physical security enclosure, e.g., by an envelope that completely encloses the device. For decades, these physical boundaries on a device-level were monitored using batterybacked mechanisms to enable detection of an attempted physical intrusion even if the underlying system is powered off. However, the battery affects the system's robustness, weight, prevents extended storage, and also leads to difficulties with the security mechanism while shipping the device. In this position paper, we present our assessment of various battery-backed tamper-respondent solutions and argue that while offering the intriguing benefit of instantaneous detection and response, the low-power nature of battery-backup contradicts a tamper-sensitive measurement, among other problems. We are therefore of the opinion that more effort should be spent towards enclosures that are based on tamper-evident physical unclonable functions (PUFs), as they are designated to provide a high level of security on the one hand and do not require a battery on the other hand. To further substantiate our argument, we summarize the work in this domain to also facilitate future research.

South Padre Island, Texas, USA: IEEE, 2018. ISBN: 978-1-5386-5762-1. DOI: 10.1109/ICDIS. 2018.00048. Abstract: Abstract—One Time Passwords (OTPs) are used to increase the security of the authentication process of networked applications. Smartphone based OTP schemes already brought usable and affordable multi-factor authentication to web applications. These schemes are also a promising approach for authentication in industrial applications. This paper introduces an industrial remote maintenance use-case that uses a smartphone based OTP authentication scheme using Quick-Response (QR) codes [1]. In addition to a main communication and password authentication channel, the proposed scheme requires an out-of-band communication channel to transmit OTPs via smartphone. While baseline security for the channels can be achieved with Transport Layer Security (TLS), Out-of-Band Authentication (OOBA) remains vulnerable to Man-in-the-Middle (MitM) attacks in environments where the authenticity of the communication partner cannot be guaranteed. In order to mitigate this problem, it is crucial to establish a secure channel association. The enhancement proposed in this paper thus cryptographically binds successful out-of-band OTP authentications to the prior established data-channel with the help of TLS channel binding [2]. Recommendations include common TLS libraries that support this feature as well as further considerations for a secure implementation.

Abstract: Reliable authentication of entities is the baseline for secure communications infrastructures and services. While traditional password authentication is still widely deployed, alternatives based on asymmetric cryptography are also available and provide an increased level of security. On the client-side, however, secret keys are often unprotected. Although constantly updated workstations are considered to be trusted environments, security breaches such as Spectre or Meltdown raised doubts in platform integrity. The presented work introduces realistic attack vectors which can be employed to extract cryptographic keys from workstations. Consequently, Hardware Security Modules (HSMs) are introduced which provide secure storage as well as secure utilisation of private cryptographic keys. Due to the huge amount of possible application scenarios, the paper focuses on an application scenario based on the widely used Secure Shell (SSH) protocol. Demonstrating that an improved level of security is not necessarily directly linked to costs, a rough summary of interesting Commercial-off-the-Shelf (COTS) devices is provided.

This final project report is written based the job training done in Public
Relation Division of Sragen Local Government for one month, starting on February
27th until March 26th, 2012.
The aims of this final project report are to explore the strategic management
of Public Relations Division of Local Government of Sragen in holding Srawung
Warga and to know the effectiveness of the program as an effort to make good
relationship between government and the public and to build image of Local
Government of Sragen as good government.
In holding the forth Srawung Warga in Sub District of Gesi public relation
division uses strategic management which is formulated in three steps. These steps
are planning, executing, and evaluating. In planning Srawung Warga, Public
Relation Division gathered information about Sub District of Gesi, determined the
venue and the participant of the event, gathered information about the new program
from other division and Local Government, arranged rundown of Srawung Warga
and Regent speech pointer, and implemented coordination with the officer of Sub
District of Gesi. The next step is executing the event based on the plan. The last step
is evaluating. The public relation division evaluates that the forth Srawung Warga
was running smoothly, but the dialogue was shorter than the plan.
The indicators to measure the effectiveness of Srawung Warga are the
numbers of participants, the participant's reaction and expression during the event,
and participant's opinion about Srawung Warga.
Hopefully, this final project report can be a reference for the Public Relations
Division of Local Government of Sragen to create better strategic management in
holding a program or an event.


Due to climate change, the importance of environmental protection, and the operation of the global supply chain influenced by the pandemic, building a flexible green supply chain model can help enterprises keep operational sustainability and strengthen competitive advantages. However, it can be found from relevant literature that research on green supply chain flexibility is still insufficient. This study aims to fill the research gap, and attempts to develop a multi-objective mixed integer programming model for a flexible green supply chain network design to maximize the profit, the amicable production level. To our knowledge, this proposed model is the first effort to take economic factors, environmental factors, supply flexibility, manufacturing flexibility, distribution flexibility and reverse logistics flexibility into account simultaneously, and can be a reference for supporting effectively management of the green supply chain network design. The research result and findings can be a reference for related academic researches and also can be used to guide the development of a green supply chain model for making better decision.

(ProQuest: ... denotes formulae omitted.) The visions and prophecies recorded in the book of Zechariah have long puzzled scholars.1 Among the more challenging ones are the prophetic sign-acts connected to the appearance of ... in Zechariah 3 and 6:9-15. Who is this enigmatic figure? What is his relationship to Joshua and the priesthood? In this essay, I will first offer a brief summary of earlier attempts to answer these questions and then proceed to suggest a new interpretation of the data. I will argue that, among other texts, Ezpk 21 -.29-32 (Eng. 21:24-27) presents us with an interpretative key to these two passages from Zechariah. I. PAST INTERPRETATION As is the case with most exegetical puzzles, there are a number of variations also among the solutions offered to the puzzle of ... (hereafter Zemah),2 Joshua, and Zerubbabel (who appears only in Zechariah 4). However, it is nevertheless possible to identify a majority view.3 According to this view, Zechariah 3 and 6 envisage a form of diarchy, a shared rule of the high priest and a Davidic king, and these chapters thus testify to the rise of the Zadokite priesthood as a political power in the postexilic Jewish community.4 As for Zemah, the original oracles referred to Zerubbabel-or even Joshua-instead, but for one reason or another, this was changed in the process of redaction. This traditional reading of the data has recently been challenged by more than one interpreter. A major contribution has been offered by Wolter H. Rose, whose monograph focuses on Zemah and Zerubbabel.5 Some of his main conclusions are as follows:6 (1) Zemah is a future messianic figure and not to be identified with Zerubbabel (or Joshua); (2) attempts to consider parts of the oracles in ch. 3 and 6:9-15 as secondary may appear to solve some problems but are based on "dubious grounds";7 (3) although the high priests influence in the temple is expanding (ch. 3) and he may possibly function as a counselor to the coming ruler (ch. 6), there is no evidence in the book of Zechariah for diarchy or the emergence of the priesthood as a political power. Another nontraditional reading has been proposed by Mark J. Boda, who agrees with Rose on most issues but sees Zechariah as emphasizing the continuing influence of prophetic and royal streams in texts traditionally interpreted as promoting the extension of priestly prerogatives.8 According to Boda, Zechariah has been influenced by-and clearly alludes to-the Jeremianic tradition of enduring but separate royal and priestly lines.9 Zechariah's agenda vis-a-vis the leadership is thus to restrain priestly aspirations rather than endorse them as has been argued in the past.10 It is beyond the scope of this essay to offer a detailed response to these three readings, but I will interact with them where appropriate. My own interpretation follows in many ways the freshly beaten path of Rose and Boda, yet departs from it at certain key points.11 II. A NEW PROPOSAL Zechariah's wide knowledge and use of earlier books and traditions is well known.12 Indeed, many details and motifs of Zechariah can be fully appreciated only when seen in light of their treatment by earlier prophets, and the present pericopae are no exceptions. While this is not the occasion for an extended survey of Zechariah's employment of existing traditions, a couple of comments are nevertheless appropriate, given the topic of the essay. First, the very opening "word of Yahweh" (1:1) coming to Zechariah refers three times (w. 4-6) to the earlier prophets and their words.13 These (and later references, 7:7,12) suggest both Zechariah's familiarity with earlier prophetic traditions and their importance to the interpretation of his own message. As Michael Fishbane has noted, "a learned preoccupation with older prophetic language is characteristic of late biblical prophecy," and Zechariah is no exception.14 Second, while some of Zechariah's prophetic language is clearly stereotypical and it is possible to discern "simple allusions" and "echoes" in the text, there are also allusions that evoke a specific earlier text or tradition that can shed light on the text containing the allusion. …


Serratia marcescens swarming behavior is characterized by continuous populational surface migration on swarming agar at 30°C, but not at 37°C. The underlying mechanism how S. marcescens population starts to initiate swarming and the temperature-dependent regulation of swarming behaviour are currently uncharacterized. We identify in S. marcescens a genetic locus that, when mutated, results in a "super-swarming" phenotype, which is not only defective in the temporal, but also in the temperature-dependent control of swarming behaviours. The gene mutated (rssA, Regulation of Serratia Swarming A) is homologous to membrane sensor histidine kinases of the two-component family of regulatory proteins, suggesting that RssA may function as a sensor of environmental conditions required to regulate swarming migration. Factors already identified to be involved in regulation of swarming migration are not affected in this mutant. These include amount of flagellum synthesis, activity of swimming motility, surfactant production, and synthesis of extracellular polysaccharide. Here we report that long chain fatty acids and temperature shift acting as the signal cues regulate S. marcescens CH-1 swarming through the RssA/RssB two component signal transduction system. We find that long chain fatty acids and temperature upshift negatively regulate the CH-1 swarming through influencing pattern of cellular fatty acid profile. The RssA-RssB two-component system mediates this response, as both partners are required to sense and transduce the signals. Fatty acid profile analysis strongly indicates that long chain fatty acid and temperature affects the signaling state of the RssA sensor protein by increasing the incorporation of the low0melting point fatty acids into membrane phospholipid. We propose that both increase in membrane fluidity at constant temperature and a temperature upshift influences fatty acid synthesis and swarming by the same mechanism. Similar phenomena of long chain fatty acid inhibition were also observed in swarming regulation of Proteus mirabilis and Salmonella typhimurium. Thus, the fatty acid profile and two component signaling pathway might provide a novel and common mechanism for regulation of swarming behaviour of not only S. marcescens, but also other swarming bacteria under different physiological culture conditions.


The 3s and 3p photoabsorption spectra of K ll and Ca m have been recorded in the 2775 eV region using the Dual Laser Produced Plasma technique. With the help of ab initia calculations made with the Cowan code and Rydberg series expansions, many 3s---tnp window resonances and 3p---tns,d transitions have been identified in these ions.


The main objective of this work is to investigate the integrability and linearizability problems around a singular point at the origin of the family of differential systems Particularly we are interested in the three-dimensional cubic Lotka-Volterra systems for (1:-1:1) resonant. We give a complete set of necessary conditions for both integrability and linearizability problems. The local existences of two independent first integrals guarantee that these conditions are sufficient as well. Furthermore, we use the Darboux method of integrability and some other techniques to show that the system admits two independent first integrals at the origin.


The risk assessment analysis is perceived as the most important stage in preparation of the major accident prevention documentation in accordance with the Directive 96/82/EC. The risk assessment alone is a complex process and several procedures and their modifications have been developed in practice, using various approaches to the task. ARAMIS (Accidental Risk Assessment Methodology for IndustrieS) methodology (Hourtlou, Salvi, 2003, ARAMIS, 2004) has been developed in order to unify the approach to risk assessment for major accidents and their impact on the environment.Project ARATech2013 – a tool for major accidents risk analysis, has been established with the aim to transform ARAMIS complex procedures into a software tool, which will simplify and make the risk assessment techniques more readily accessible. It is the coherence of the ARATech2013 tool and the number of prearranged and recommended steps that provide the wider user base with a useful alternative to the commonly used and often technically and methodologically challenging deterministic and probabilistic approaches used for risk assessment.ARATech2013 is a web-based modular tool, which enables to alternatively expand the functionality of the tool or gives its users the option to follow a simple pre-selected pathway without having to follow the entire major accidents risk assessment process. The tool is based on the following three core modules:risk source assessment module,representative scenarios determination module,accident impact assessment module.The risk source assessment module presents the initial stage of the risk analysis process. The users use the module to establish the basic information about the facility, i.e. a list of all types of equipment containing hazardous substances, physical - chemical properties of hazardous substances, their physical state and amount. The application automatically identifies the potentially hazardous equipment to undergo further detailed analysis and matches this equipment with appropriate potential critical events. The user is provided with an ability to add supplementary information for determination of potential domino effects.The representative scenarios determination module computes the frequency of various hazardous effects for the determined critical events. Each critical event is automatically assigned generic fault trees (Fault Tree Analysis - FTA) and event trees (Event Tree Analysis - ETA), which can be further modified by the user to match the real situation in the given establishment. The user has the option to use a generic frequency for each critical event or to determine the frequency using the in-built Fault Tree Analysis. The module offers a database of complex check lists of safety functions and barriers, which the user can assess and apply individually to each fault or event tree. This makes the tool highly valuable for assessing the effectiveness of risk management systems.The accident impact assessment module is an independent module for modelling of the hazardous event and the spatio-temporal distribution of hazardous effects. The model distinguishes among the different types of release of the substance from the equipment, the consequent cloud formation and its dispersion with the toxic, radiative or pressure effects. The module is interlinked with a web mapping portal for a quick projection of the impact of the hazardous event.


In accordance with the International Pharmaceutical Excipients Council (IPEC), excipients are any component used during the production procedure or included in a finished medicinal formulation but which is not an active ingredient or a prodrug. The USP-NF defines Forty different types of additives for usage in medicines. Another of the classes, organoleptic compliance, gives medicines flavor and color. Medicine is made more palatable by adding flavors.  Again, depending on where they originate, these tastes are classified as natural, artificial, or natural and artificial (N&A). To deliver not only tastes but also a delightful flavor, flavoring agents are used in pharmaceutical preparations such edible syrup, oral suspension, herbal remedies, pills, tablets that can be chewed, bubbly tablets, easily dispersed tablets, and ODT. They are used to boost patient compliance or enhance the taste of therapeutic dosage forms.


The manufacturing tolerances of a stencil-lithography variant, membrane projection lithography, were investigated. In the first part of this work, electron beam lithography was used to create stencils with a range of linewidths. These patterns were transferred into the stencil membrane and used to pattern metallic lines on vertical silicon faces. Only the largest lines, with a nominal width of 84 nm, were resolved, resulting in 45 ± 10 nm (average ± standard deviation) as deposited with 135-nm spacing. Although written in the e-beam write software file as 84-nm in width, the lines exhibited linewidth bias. This can largely be attributed to nonvertical sidewalls inherent to dry etching techniques that cause proportionally larger impact with decreasing feature size. The line edge roughness can be significantly attributed to the grain structure of the aluminum nitride stencil membrane.

This symposium contribution scrutinizes Zahl's treatise on the Holy Spirit and Christian experience from the perspective of his utilization of Augustine, Luther and Melanchthon. It exposits his argument as a critical retrieval of the early Reformation doctrine of justification by the Spirit's sanctification which is the gift of faith, recognizable as affective transformation from servile fear to filial trust. It qualifies his genealogy of the discrediting of such affective experience in modern Protestant theology by tracing it to the Osiander controversy and its resolution in the 1580 Formula of Concord's separation of justification from the Spirit's sanctifying work in bestowing faith as the gift which receives the gift of Christ in his joyful exchange with the sinful.


Relevance Currently, the requirements for modern tomato hybrids are increasing both from consumers and from producers. Modern tomato hybrids in extended circulation should yield at least 60 kg / m 2 , be distinguished by high quality of fruits, early ripeness, possess manufacturability, resistance to major diseases. Along with the traditional form of fruits, hybrids with original shape, color, taste and aroma are interesting for manufacturers. Methods The aim of the research was the variety study of indeterminant F 1 hybrids of tomato breeding of the company "Gavrish" in JSC "Teplichnoye" of the Tambov region. Studies were conducted in 2017-2018 in the extended and summer-autumn turnover in the conditions of JSC "Teplichnoye" of the Tambov region in accordance with generally accepted recommendations for research with vegetable crops in greenhouses. The objects of the study in extended circulation were tomato hybrids: F 1 Bao Bab, F 1 Baloven, the F 1 Torero hybrid was taken as a control. In the summerautumn turnover, a study was made of the rose hybrid – F 1 Panthera; the Rosario F 1 hybrid was used as a control; a hybrid with a plum-shaped fruit – F 1 Armata, control – a hybrid F 1 Lezghinka. Results According to the results of the study of tomato hybrids, the selection of the Gavrish company at the enterprise made the decision to grow it in extended circulation and increase the area under F 1 Baloven, in the summer-autumn turnover under the F 1 Panthera hybrid.


This research focuses on weathering resistance of painting material on mortar. Four kinds of painting materials (acrylics paint, epoxy resins paint, inorganic water-based paint, and all weather paint) were used on mortar. Three deterioration processes — accelerated deterioration of 572 hours in oven at 50 and 75 degree C, accelerated deterioration of 2000 h of mist testing, and 572 hours Xenon light deterioration — were employed to discuss the properties of each painting material. Experimental results show that compressive is little change with different painting materials in deterioration processes. With regard to the deterioration in solar simulation, color and gloss significantly change before 200 hours; classification belongs to a distinct color change. And the acrylic paint has greatest change. Although the temperature deterioration on the mechanics properties of specimens are slightly, but water permeability and chloride diffusion coefficients have larger changes, should be able to react to the temperature on the growth of micro-cracks.


The terminology of the solid materials that result from the conversion of coal, primarily for power production, has gradually changed, resulting in a variety of common terms being used interchangeably and frequently incorrectly. A large volume of materials produced by power plants consuming coal are referred to as coal combustion by-products (CCBs), or more recently as coal combustion products (CCPs), by those in the power industry, the ash marketing industry, and most users of these materials. These same materials are frequently termed coal combustion wastes (CCWs) by regulators, citizen groups, and others. The authors will refer to these materials as CCBs in this document. The solids included in these categories are fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) material. Immediately, it must be pointed out that FGD material is a by-product of removal of sulfur gases at these power plants and not related to the combustion process. Additional inconsistencies in terminology and definitions can be found in the common usage of many of these terms to refer to solid materials produced from advanced combustion systems such as fluidized-bed combustion (FBC) and solid materials produced from blended fuels. These inconsistencies can provided misleading inferences related to the utilization of CCBs. This paper discusses terminology and definitions related to CCBs from formal sources such as EPA (U.S. Environmental Protection Agency) and ASTM (American Society for Testing and Materials) and from common usage.

The Center for Collaborative and Adaptive Sensing of the Atmosphere (CASA) developed and deployed four polarimetric and Doppler-capable distributed, collaborative and adaptive X-band radars in Oklahoma with the capability to detect and track tornadoes and storms in the lower troposphere with high spatial and temporal resolution. This paper presents an analysis of the performance of X-band rainfall estimation composite algorithms and the conventional reflectivity-rainfall relationship. The polarimetric estimators are developed by different combinations of radar products including horizontal equivalent reflectivity (Zh), differential reflectivity (Zdr) and specific differential phase (Kdp)- The Micronet Little Washita rain gauge network is used for validating rainfall estimates of the KCYR CASA radar. In addition, NEXRAD WSR-88D KFDR radar data are analyzed and compared with the rain gauge network and the CASA radar estimates. Fourteen hours of data collected during August 2006 from three different storms are analyzed. Both convective and stratiform events are represented in the radar data analysis. An accuracy of point radar measurement is assessed for different rain intensities. Results demonstrate an improvement in hourly rainfall accumulation estimation for average rainfall intensities beyond 5 mm/hr with the use of polarimetric estimators. An increase in absolute difference standard error with distance by the use of absolute difference in radar and rain gauges estimates is also evaluated.


This work studied the new requirements of the tacit professional quality on medical students in the era of "Wise Information Technology of 120", and aimed to explore ways and means to cultivate qualified medical students. The research group used literature review, research visits and other methods to study. The innovation point is that under the framework of collaboration between medicine and education, doctors and medical students are the research objects respectively. As a result, based on the rules and characteristics of their respective tacit quality formation, the long-term educational mechanism of establishing political-school-enterprise linkage can be summarized and a new cultivation path of diversified education


Eicosanoids play important roles in the central nervous system (CNS).'.* However, much is unknown about the pharmacokinetics of the eicosanoids and their precursors in the CNS. One of several unanswered questions is: How do essential fatty acids enter the brain from the blood? It is clear that the eicosanoids are synthesized in the brain from essential fatty acids.3 Since essential fatty acids cannot be synthesized in situ, they must enter the brain from the blood, by mechanisms that are unclear (see be lo^).'^^ Second, the eicosanoids, including the prostaglandins and leukotrienes, do not readily enter the brain from the blood when they are injected into the blood.' An excellent example is the disposition of intravenously injected leukotriene C in the CNS; this eicosanoid does not enter the brain or cerebrospinal fluid (CSF) to any degree after intravenous inje~tion.'.~ Finally, there is substantial evidence that eicosanoids, including the peptidoleukotrienes and prostaglandins, are transported between the CNS-especially the extracellular space of the brain and the CSF-and blood by specific, carrier-mediated transport systems within the CNS.2.5,6t7.8 The purposes of this communication are to review: ( 1 ) how fatty acids, the precursors of eicosanoids, enter the brain from the blood; and (2) how the peptidoleukotrienes and prostaglandins traverse the blood-brain and blood-CSF barriers. Both of these eicosanoids are transported from the extracellular space of the brain and C S F into the blood by carrier-mediated active transport systems within the choroid plexus and possibly the brain ~apillaries.~'~. ' .~ Before beginning, the anatomical and physiological basis of the blood-brain and blood-CSF barriers is worth briefly reviewing.'.'' The brain is protected from fluctuations in its internal milieu better than any other organ in the body.'.'' This is accomplished, a t least in part, by the blood-brain and blood-CSF barriers.'.'" I t is worth noting that there is no barrier to the diffusion of substances between the extracellular space of the brain and the CSF. The anatomical systems that isolate the brain from the blood include the cerebral capillaries, which are joined by tight endothelial junctions and are termed collectively the blood-brain barrier, and the choroid plexus, of which the epithelial cells are also joined by tight junctions.','" Moreover, the C S F compartment is surrounded by the arachnoid membrane, which is similarly joined by tight junctions.'.'' Thus, both the brain and CSF are isolated from the blood by anatomical barriers. These barriers are effective in retarding the entry into the brain of large and small (e.g., mannitol and salts) water-soluble molecules by simple diffusion.'.'' In contrast, there is no specific anatomic barrier to the transport of lipid-soluble substances between blood and brain.'.'' It is worth noting that the eicosanoids and their long-chain fatty acid precursors are almost completely ionized a t pH 7.4 and would not be expected to be transported through the blood-brain or blood-CSF barriers in their ionized forms3 Moreover, these long-chain fatty acids are extensively bound to plasma proteins, a phenomenon that should further retard their exit from plasma.' The anatomical blood-brain and blood-CSF barriers, if unmodified, would preclude the proper function of the brain because they would exclude the water-soluble nutrients required for the maintenance of the viability and functions of nerve cells.'~'O


Although concrete is often patched using cement-based repair materials, these materials can generate cracks and shelling which decrease concrete structure durability. This study investigates the properties of the interface between the concrete and polymer-modified cement mortar repair materials in order to improve the durability of concrete structures repaired by the aforementioned materials. Adhesive strength and water permeability tests were conducted. Results showed in the case of spray-on repair material, cracks often appeared at the interface between the concrete and between the construction layers of the repair material because of the difference in expansion and the shrinkage behavior. The progress of these cracks into the concrete was very small under test conditions. Resistance to water permeability was smaller along the interface between concrete and the repair material, while adhesive strength in the interface tended to improve as the material aged.


East Kent Health Authority is to appeal against a High Court ruling which the Department of Health believes could threaten the cervical screening programme throughout Britain. Backed by the NHS Litigation Authority (NHSLA), the health authority is seeking to overturn a judgment in which it was found negligent in classifying four cervical slides taken from three women as negative.

Introduction: The Industrial Revolution was a milestone in world development, but as every innovative process, it has also brought adverse situations, especially to the health of the worker. The beginning of the industrial process was marked by the repetitiveness of movements and monotony at work. Subsequently, the automation developed and modified the form of production. However, despite the improvements in the industry, the same effort is still noted, characterized by the exhaustive repetition of movements, the requirement of the same muscular group daily and monotony, factors that cause stress, musculoskeletal injuries and occupational accidents. The objective of this research was to assess the index of workers with musculoskeletal injuries. Methodology: The study was developed in two sectors of a slaughterhouse located in the south of Brazil: chicken's wing cut sector and platform sector. The observation, in situ, allowed the ergonomic analysis through the Ovako Working Posture Analyzing System (OWAS) method to assess the ergonomic risks of the postures based on the position of the back, arms, and legs of the workers. Time and methods were analyzed, as well as the medical records of all workers, which were registered and assessed. For the statistical analysis, workers were divided into a) uptime, b) workers who had already exercised demanding work activity of physical exertion and/or repetition of movements and the form of removal (with medical low or without medical low) and, c) by gender. Results and discussion: Through the use of the OWAS method, it was verified that workers from both sectors are not exposed to ergonomic risk. Therefore, hypothetically, they would not be subjected to musculoskeletal injuries. These results were then compared with the medical records and there was disagreement between the result of the ergonomic method and the number of injured workers. Women were the most affected by the musculoskeletal injuries. Regarding the male universe, the majority of mean suffering from musculoskeletal injuries were those who had previously worked with the activities that required force and/or repetition of movements. Conclusions: It was determined that the index of injuried workers were 25% of women in the wing cut, and 17% of men in the platform sector, which was not coherent with the application of the Ovako Working Posture Analyzing System method. It is believed the main reason is that the method does not consider the movements repetitiveness which characterises the activity. Therefore, it would be helpful for the analysis that the ergonomic study is performed using several tools, so that the result is reliable, given the dissonances that may exist between methods and means of analysis.


A Christian worldview that takes seriously the idea of personhood as a holistic unity presents an ideal perspective from which to explore human behavior as an expression of biological, psychological, and social influences (the "biopsychosocial" perspective now common in psychology) as well as an expression of spiritual realities that, while often expressed through biopsychosocial media, are not simply 'explained away' by them. A Christian worldview that holds that human beings are a unity of biological, psychological, social, and spiritual realities creates an opportunity for theoretical integration and holistic practice, but it also creates practical tensions regarding how to discern the root causes of behavior (e.g., biological, psychological, social, or spiritual etiology) and attempting to discover the best way to intervene when impairment of functioning is noted (e.g., whether biological therapy, psychotherapy, social intervention, or religiously-based interventions are called for). Additionally, there are ethical and legal issues that must be taken into consideration by Christians who are licensed mental health practitioners, especially when hypothesized causes or proposed interventions stand somewhere between recognized secular interventions and specifically religious interventions. In this article, these topics are addressed both as theoretical issues about how best to conceptualize human behavior and the causes of impairment, as well as practically in regard to how to proceed in evaluating and using religiously-based interventions. Many perspectives about what role spirituality may play in mental and physical health and illness have been offered throughout history, ranging from the view that religious belief inevitably leads to mental illness, on one extreme, to the view which claims that there are only religious solutions for psychological or medical problems on the opposite extreme. The perspective that sees religion and psychological health as incompatible was common in psychology several decades ago, as illustrated by the following quotations from Albert Ellis, one from early in his career and one shortly before his death: In most respects religion seriously sabotages mental health. (Ellis, 1980, p. 5) Try to avoid a doctrinal system through which you are dogmatically convinced that you absolutely must devote yourself to the one, only, right, and unerring deity.... Otherwise, in my view as a psychotherapist, you most probably are headed for emotional trouble. (Ellis, 2002, p. 365) Although Ellis modified his perspective somewhat in later years, his comments are prototypical of what might be called naturalistic metaphysical extremism. Naturalistic metaphysical extremism assumes that human nature indeed all of nature - is a purely naturalistic system and that any reliance on religious systems is likely to be damaging psychologically. While many psychologists adopt naturalistic assumptions, it is probably fair to say that few of them occupy the extreme position that sees religion and mental health as incompatible. For the purpose of the present discussion, it is the assumption that religious belief is pathological that is being labeled extremism rather than the quest for naturalistic explanations per se. An opposing extreme casts suspicion on natural explanations and interventions because of what might be called spiritualistic metaphysical extremism. The perspective that views mental and physical health as having only religious cures is sadly illustrated by the death of 15-month-old Ava Worthington, whose parents were members of a small sect called the Followers of Christ. Ava, who had pneumonia and a secondary blood infection, was treated solely with prayer in accordance with her parents' religious beliefs; she would almost certainly have been saved with a course of antibiotics (Faith Healing, 2008). This was not an isolated incident; a decade earlier, a newspaper reporter investigated the deaths of 78 minors that occurred during the previous 30 years among the small Followers of Christ sect, and concluded that over a quarter of the deceased children would have survived with simple medical treatment (Von Biema, 1998). …


ABSTRACT Dephosphocoenzyme A (dephospho-CoA) kinase catalyzes the final step in coenzyme A biosynthesis, the phosphorylation of the 3′-hydroxy group of the ribose sugar moiety. Wild-type dephospho-CoA kinase fromCorynebacterium ammoniagenes was purified to homogeneity and subjected to N-terminal sequence analysis. A BLAST search identified a gene from Escherichia coli previously designated yacE encoding a highly homologous protein. Amplification of the gene and overexpression yielded recombinant dephospho-CoA kinase as a 22.6-kDa monomer. Enzyme assay and nuclear magnetic resonance analyses of the product demonstrated that the recombinant enzyme is indeed dephospho-CoA kinase. The activities with adenosine, AMP, and adenosine phosphosulfate were 4 to 8% of the activity with dephospho-CoA. Homologues of the E. colidephospho-CoA kinase were identified in a diverse range of organisms.


In December 2019, SARS-CoV-2 caused coronavirus disease (COVID-19) distributed to all countries, infecting thousands of people and causing deaths. COVID-19 induces mild sickness in most cases, although it may render some people very ill. Therefore, vaccines are in various phases of clinical progress, and some of them being approved for national use. The current state reveals that there is a critical need for a quick and timely solution to the Covid-19 vaccine development. Non-clinical methods such as data mining and machine learning techniques may help do this. This study will focus on the COVID-19 World Vaccination Progress using Machine learning classification Algorithms. The findings of the paper show which algorithm is better for a given dataset. Weka is used to run tests on real-world data, and four output classification algorithms (Decision Tree, K-nearest neighbors, Random Tree, and Naive Bayes) are used to analyze and draw conclusions. The comparison is based on accuracy and performance period, and it was discovered that the Decision Tree outperforms other algorithms in terms of time and


A quasi-stationary particle-in-cell code based on the use of boundary fitted coordinates has been adapted for use in the simulation of magnetron injection guns for gyrotrons. In addition, a ray tracing version has been written, since this is more convenient for parameter studies. Results calculated with these codes are in good agreement with experiment. The results are also compared with those calculated by other codes. The influence of electrode shape on beam quality, starting from a synthesis program, is investigated.
