We herein report a mercury-free approach for the sensitive determination of trace Pb 2+ in seawater using differential pulse stripping voltammetric (DPSV) method with a novel columnar glassy carbon electrode (CGCE). Compared with the conventional disk glassy carbon electrode with the same diameter, it has much larger electrochemical area (0.627 ± 0.003 cm 2 ). The CGCE shows good accumulation ability and consequently acceptable behavior which makes it suitable as a working electrode in the DPSV determination of Pb 2+ with the great advantage of the avoidance of harmful mercury. Using acidified artificial seawater as supporting electrolyte, there was a good linear relationship between the peak currents and the concentrationofPb 2+ intherangeof0.6~140.0gL -1 withadetectionlimitof0.3µg/L(S/N=3)whenthe accumulation time was 300 s. The method was employed to determine trace levels of Pb 2+ in real seawater

Predicting thermometric performance for diverse materials will facilitate the selection and design of nanothermometers to meet complex environment and specific signal output with saving a lot of time and expense. Herein we explore and unveil the thermal coupled thermometric performance of Er3+/Yb3+ co-doped a set of host lattices via the chemical bond theory of complex crystals. The unknown B and ΔE values of the thermometry are accurately estimated by the chemical bond parameters, further deepening our cognition of the correlation between luminescence properties of Er3+ ions and microscopic crystal structure. This allows us to precisely forecast the thermal coupled thermometric performance of Er3+ for varying host lattices in advance.


Exploratory spatial data analysis(ESDA) can finely reveal the characteristics of economic growth of a region in relation to its geographical environment,and therefore is a powerful tool to help us better understand-ing the spatial-temporal dynamics of the distributions of economic factors in each region.The study of the spa-tial distribution of per capita GDP of 284 counties in the Loess Plateau region since 1990 using ESDA proved its role in investigating the rules of distribution and evolution of social or economic development.And several points can be highlighted.First,ESDA reveals significant positive global and local spatial autocorrelation of per capita GDP in the Loess Plateau region throughout the period 1990-2007.Second,the analysis of scatter plots and local indicators of spatial association(LISA) over the period indi-cates that there are four significant regional clusters persisting over time.The first is a significant High-High(HH) type of clustering,located mainly in Inner Mongolia—north Ningxia—north Shaanxi in the Loess Plateau region.The other HH forms of clustering are located in Northwest Henan and Southeast Shanxi.The largest ar-eas of low-low(LL) type of clustering are primarily located in the south of Gansu,the south of Ningxia and east of Gansu.Third,the comparative analysis of per capita GDP and average growth rates of per capita GDP suggests that the development of per capita GDP in the Loess Plateau region is mainly in a way of polarized growth in the past 20 years.And it is predictable that this trend will persist,and even get stronger in the near future.Until now there are no characteristics of β-convergence detected in the Loess Plateau region.Finally,the stable spatial patterns in Loess Plateau region indicate two kinds of economic growth modes.One is the normal economic growth pushed by industrial agglomeration,and the other is the opportunistic eco-nomic growth pulled by energy/resources exploring.The latter is far more powerful in promoting the level of per capita GDP,but always with problems of singleness of industrial type and lack of stability,sustainability and in-terference immunity during its working process in pulling economic growth.

The teacher is an important element in the world of education, therefore the hard work of a teacher should be appreciated, one of it is appointing the teacher to be a permanent teacher, and entitled to receive compensation and welfare guarantees, but the fact is that many PJOK teachers have not been appointed as permanent teachers. In educational institutions, especially PJOK teachers in Modo sub-district who carry out their professional duties in elementary school (SD/MI), so many PJOK teachers with GTT status (non-permanent teachers) intentionally work concurrently from one institution to another. So the purpose of this study is to find out the work motivation of non-permanent PJOK teachers (GTT) SD/MI in Modo sub-district. The method used is a qualitative descriptive method which was carried out for three consecutive months in order to test the validity of the data. The motivation indicator used is the theory of needs by Gibson and friends, with the result of an existence motive in which PJOK teachers are willing to change teaching places in order to meet their basic needs. The second is a social need because teaching as a PJOK teacher in various basic education institutions will increase the relationships that benefit them, and the third is the need to develop which by being a PJOK teacher they can benefit their students and be able to develop their skills.


Elliptical (E) and lenticular (S0) galaxies lack the substantial interstellar medium (ISM) found in the star-forming spiral galaxies. However, significant numbers of E and S0 galaxies are known to contain detectable amounts of interstellar matter (e.g., Jura 1988). Thus, it is worth investigating whether these galaxies are currently able to form stars from their ISM, or whether they should be consigned to the dustbin of inert objects (Thronson and Bally 1987). The results strongly imply that current star formation is responsible for NGC 4710's far infrared and radio continuum properties. If this is indeed the case, then one expects this star formation to be fueled by molecular gas, which is presumably dominated by H2 and can be traced by the CO-12 J=1 to 0 line. Both Kenney and Young (1988) and Sage and Wrobel (1989) have detected such an emission line from NGC 4710, and infer the presence of more than 10(exp 8) solar mass of H2. The origin of the molecular gas in NGC 4710 remains a mystery. The galaxy is very deficient in HI (Kenney and Young, in preparation), suggesting that it originally was a spiral galaxy from which the outer, mainly atomic, gas was stripped by the ram pressure of the Virgo Cluster's intracluster medium, leaving only a central interstellar medium (ISM) rich in molecular gas. Alternatively, the CO may have originated via stellar mass loss with subsequent cooling, cooling flows, or capture from a gas-rich companion. Information on the morphology and kinematics of the CO can be compared with that of the galaxy's other gases and stars to distinguish among these various possible origins for the molecular gas. Major axis CO mapping with single dishes indicate an unresolved source. Thus, a millimeter array is currently being used to image NGC 4710 in CO to provide the needed morphological and kinematical data.

DOI: 10.21276/sjams.2017.5.10.35 Abstract: Extended-spectrum β-lactamase (ESBL) production is the major resistance mechanism to β-lactam antibiotics in Enterobacteriaceae. In addition, emergence of plasmid-mediated quinolone resistance (PMQR) in ESBL-producing isolates has become a global threat for treatment of these infections. The aim of the study was to analyze ESBL production among Klebsiella species by combined disc diffusion method and to detect fluoroquinolone resistance by Kirby Bauer disc diffusion method along with the MIC by Estrip method. A total of 200 isolates of Klebsiella species were collected from different non repeated clinical samples and Antibiotic susceptibility test with special reference to fluoroquinolone antibiotics was performed by disc diffusion and ESBL production was confirmed by combined disc diffusion method. Among 200 Klebsiella isolates, 121(60.5%) were ESBL producers. Out of these 121 ESBL isolates, Multidrug-resistance was observed in 80.9 % isolates. Fluoroquinolone resistance was detected among ESBL isolates of which; 76% were resistant to nalidixic acid and 76% to ciprofloxacin, 74.4% levofloxacin, 76% to sparfloxacin and 76% to moxifloxacin. For carbapenem antibiotics; 55.4 % and 54.5% ESBL isolates were susceptible to imipenem and meropenem respectively. Resistance to Piperacillin and Piperacillin/tazobactam were 90.1% and 72.7%, respectively. Bacterial resistant profile found to be quite high to ESBL production with quinolone resistance in the majority of the Klebsiella isolates, which are emerging because of prescription of improper antibiogram schedules.


This paper explores the macroeconomic and welfare implications of aging and social security reform in Japan. Based on the overlapping generations model with idiosyncratic income risk, we demonstrate that aging induces capital deepening and wage increase in the transition path. We consider four social security reform plans; (1) the reduction of the replacement rate by half, (2) full privatization, (3) capital income tax, and (4) consumption tax. We compute the transition paths of each case, and find that the introduction of capital income tax improves the welfare of the young and future households based on the cohorts' viewpoint. On the contrary, the introduction of consumption tax does not improves the social welfare of the economy because of intragenerational inequality and substitution eect. Further, we show that under the transition, the earnings profiles become a more hump-shaped and consumption profiles become steep with the changes in the replacement rate.


Significance Mitochondria play a vital role in the progression of ferroptosis, an iron-dependent programmed necrosis that is associated with a series of diseases, including cardiomyopathy and heart ischemia–reperfusion injury. However, the molecular mechanism underpinning the link between mitochondria and ferroptosis remains incompletely understood. Here, we found that mitochondrial outer membrane protein FUN14 domain–containing 2, also known as HCBP6 (FUNDC2), could interact with and destabilize SLC25A11 to affect mitochondrial glutathione (mitoGSH) levels, and thus to regulate ferroptosis. This FUNDC2–SLC25A11 axis serves as a pathway for the regulation of ferroptosis through mitochondria and provides insights into the therapeutic interventions of ferroptosis-related diseases.


Once the tide recedes and leaves a significant amount of stranded seaweed on the coast, marine macroalgae pose a serious threat to the surrounding area. Through this work, we considered a large-scale application of stranded macroalgae in building construction. For the first time we studied the impact of incorporating Sargassum mitucum seaweed fiber in replacement of flax fiber used for a standard structural cob. Thus, cob specimens were elaborated and analyzed to evaluate their compressive and hygrothermal performances. It was found that the compressive strength and water vapor resistance factors of cob decreased with the algae content. Additionally, the obtained results showed that a cob made with Sargassum muticum algae presented better thermal (insulation and inertia) and hygroscopic properties than those of a cob made with a flax fiber. Indeed, the replacement of flax straw by algae lead to a reduction in the thermal conductivity by 38% when compared to the standard cob with 2.5% of flax straw fiber. Consequently, numerical simulation showed a reduction in the energy needs in buildings made with an algae-based cob when compared to those made with a flax-based cob. This study can contribute to a global environmental and economic issue, i.e., the valorization of brown algae on a large scale. Indeed, the worldwide knows the largest sea of sargassum algae extent measures over 8850 km2. This huge mass of brownish algae is expanding every year, which now covers an area from Africa to the Caribbean. It weighs more than 20 million tons and extends from the Gulf of Mexico to the west coast of Africa. We show that stranded algae, which are considered as wastes, have the ability to improve the mechanical and hygrothermal performance of cob-based material.


The utility model discloses an electronic intelligent accelerator stepping misoperation prevention system, which comprises a singlechip; the input end of the singlechip is connected with three sensors: an acceleration sensor, a radar sensor and a rotating speed sensor, wherein the acceleration sensor is connected with an accelerator pedal; the radar sensor is arranged at the front end of an automobile body; the rotating speed sensor is arranged on an axle of an automobile wheel; the output end of the singlechip is connected with two stepping motors: a first stepping motor is connected with a brake pedal through a brake cable; and a second stepping motor is connected with an oil limiting valve in an oil line. The accelerator stepping misoperation prevention system transmits the acquired safety distance in front of an automobile, the driving speed and the acceleration achieved by stepping the accelerator pedal to the singlechip; and a program is adopted to judge the real intention of a driver. If an accelerator is stepped mistakenly, the oil inlet quantity of a high-pressure oil pipe is limited, and the stepping motors operate the brake pedal to brake, so that the accelerator stepping misoperation problem is solved; the traffic accidents are effectively reduced; the operation of the automobile is more intelligentized; and the safety performance of the automobile is improved.


IN the course of studies of the development of lesions produced in experimental infection with Mycoplasma mycoides subsp. mycoides (M. mycoides) observations on the influence of polysaccharide substances released by the organism into culture media were made (Hudson, Buttery and Cottew, 1967; Lloyd, Buttery and Hudson, 1971). These substances had systemic effects leading in about two-thirds of cattle to reactions of varying severity in which respiration was increased and coughing occurred, and there was sometimes salivation, incoordination and collapse. In the animals that died there was congestion of the lungs, trachea, bronchi and parts of the alimentary tract; haemorrhage and oedema were seen in lung alveoli (Lloyd et al., 1971). An extracellular glucan obtained from a mycoplasma strain (L2917) associated with arthritis in cattle (Simmons and Johnson, 1963) caused collapse in cattle (Hudson et al., 1967); an animal that died showed intense congestion of the mucosa of the trachea and bronchi at necropsy. Other reports of acute effects include one by Longley (1951) of collapse from shock in goats and sheep after intravenous injection of effusion from a local mycoplasmal lesion of a goat. The intoxicant effects of mycoplasma, mycoplasma cellular extracts and whole cultures have been reviewed by Kaklamanis and Thomas (1970). The present report relates specifically to the effects of the extracellular polysaccharide of M. mycoides. It is obtained as a supernate from the culture medium after removal of the cells by centrifugation. Its pyrogenic activity has been uniformly low or absent. The aim of these investigations in the intact animal was to see if any indication could be obtained of how the material might influence the development of the natural disease produced by M . mycoides, namely contagious bovine pleuropneumonia (CBPP).


"THE induction-current of weakest strength which produces a contraction of the heart, does not produce the weakest of possible contractions, and the extent of the latter also does not exceed an impassable maximum, when the intensity of the exciting current is increased. On our object (the ventricle of the frog's heart) the induction-current either produces a contraction, or it does not; and when it does the former, it causes at the same time the most extensive contraction which the induction-current at a given time can produce. It therefore follows directly that the cause why the apex of the heart con'tracts to different extents is to be sought in the variable properties of its muscular fibres." This fundamental law of the movement of the cardiac muscles is one of the most important results of the investigations of Bowditch, "Ueber die Eigenthiimlichkeiten der Reizbarkeit, welche die Muskelfasern des Herzeng zeigen." (Arbeiten aus d. physiologischen Anstalt zu Leipzig, Jahrgang, 1871, p. 174.) Now in the course of these important experiments several remarkable phenomena, constantly recurring under quite distinct conditions, appeared, to whose interpretation it appears necessary to limit the fundamental law. But just as the disturbances in the course of the planets, instead of threatening the universality of Newton's law of gravitation, as often as their cause was discovered, confirmed this most beautifully, so have-si parva licet componere magnis -the peculiarities which appeared to disturb the simple view of the irritability of the heart, by continued testing, with the

In power electronic converters, reliability of DC-link capacitors is one of the critical issues. The estimation of their health status as an application of condition monitoring have been an attractive subject for industrial field and hence for the academic research filed as well. More reliable solutions are required to be adopted by the industry applications in which usage of extra hardware, increased cost, and low estimation accuracy are the main challenges. Therefore, development of new condition monitoring methods based on software solutions could be the new era that covers the aforementioned challenges. A capacitance estimation method based on Artificial Neural Network (ANN) algorithm is therefore proposed in this paper. The implemented ANN estimated the capacitance of the DC-link capacitor in a back-toback converter. Analysis of the error of the capacitance estimation is also given. The presented method enables a pure software based approach with high parameter estimation accuracy.

The presence and distribution of four antagonistic Argentine ant supercolonies within closed areas in Kobe Port, Hyogo Prefecture, Japan, were revealed. Three of them had already caused severe reduction of ant species richness, whereas one coexisted with many indigenous ant species. We detected two contact zones of Argentine ant supercolonies, where indigenous ants occurred. Studies in these contact zones would provide insight into the hypothesis that lack of intraspecific aggression is responsible for the displacement of indigenous ant s by Argentine ants, although the competitive ability of one supercolony described above must be carefully examined.


Objective To detect Epstein-Barr virus DNA load in peripheral blood lymphocytes of nasopharyngeal carcinoma(NPC) patients, and analyze its relationship with the clinical stage of NPC. Methods Real-time quantitative PCR was used to detect EB virus DNA in peripheral blood lymphocytes of 87 NPC patients in our hospital from January 2012 to January 2013, and relationship between the DNA load and NPC clinical stage was analyzed. Results The positive rate of EBV-DNA in NPC patients was 82.76%(72/87), and a median level of EBV-DNA was 7.58×106copies/ml. The copy numbers of EBV-DNA for stage I, Ⅱ, Ⅲ and Ⅳof NPC were(4.25±1.14)×103,(4.56±0.68)×104,(7.88±1.65)×105, and(8.09±1.65)×106, respectively, showing a gradually increased tendency from stage I to stage Ⅳ, and the difference was significant(P0.05). Conclusion EBV-DNA load in peripheral blood lymphocytes is positively correlated with the clinical stage of patients with NPC,suggesting that EBV-DNA load is closely related to NPC progress, and it can be used as an effective indicator of disease monitoring and efficacy judgement.

In the context of changes in a person's health, not only the psychological, material, social and environmental factors must be considered. Rather, the normative, non-material demands of nursing science, along with theological and anthropological considerations and empirical studies of health psychology and medicine, all provide evidence that it is especially spiritual elements which must be taken into account. To the extent that spirituality belongs to being human, has the potential to be activated and has relevance for health, the question arises as to where there is room for this in the curricula of German nursing programs. This article addresses the relevance of spirituality in nursing, examines the inclusion of spiritual educational content in the outline curricula of the German Federal States, and takes a look at the situation in nursing education in the U. S. A. From these developments in Germany and the U. S. A., the article considers the opportunities, limits and starting points for qualifying nurses in spiritual support in a way that is fit for the future.


A large seamless display that could be set up rapidly, operated effectively, and moved quickly would be a great value to the military. Such a display system would be even more beneficial if it consisted entirely of easily available, commercial, off-the-shelf components, not dependent on a single supplier. We have designed a seamlessly tiled projection system to meet these needs. The system consists entirely of easily available, commercial, off-the-shelf equipment. We created software that records the location of projected images as detected by a digital camera, computes the movements necessary to align the images, and drives the projection lenses to align the seamlessly tiled display. We developed a method for rapid mechanical mounting of the projectors and camera. We chose commercial folding stands and a mirror-based alignment method that accelerated the mechanical setup. In field trials, our prototype was operational within one-half hour of opening the shipping cases.


Despite increasing knowledge intensity in product development, there is still a lack of understanding regarding the dynamic interrelations of knowledge types, stakeholders and artefacts in value creation processes.This dilemma counts also for engineering science as a discipline. This paper proposes a conceptual framework that allows for the analysis of dynamic knowledge flows in practical design processes and fundamental engineering research. Results from exemplary applications on two use cases will be used to illustrate its overall applicability and its potentials for science and industry.


It is very essential for procuratorial organs to set up a case quality management center in terms of building scientific management system in the organs.Case management itself actually realizes their internal right of supervision.As for these procuratorial organs that are granted the right of supervising law,the mode of case quality management embodies,to some extent,that fact that power restricts power.Well-application of the window(case quality management center) can rationalize the distribution of procuratorial resources.The core of case quality management is laid upon the efforts of strengthening case quality.


This paper discusses the results of a fractographic investigation of ancient pottery. The project was undertaken in cooperation with archeologists from the Institute of Archeology and Ethnology of the Polish Academy of Sciences (IAE PAN) with the objective of applying methods for characterising structure and properties commonly used in materials science and engineering to the study of ancient pottery.


A weighted measurement fusion estimation algorithm,not constrained by whether each sensor measurement matrix is the same or not or whether measurement noises are correlated or not,is presented by using full-rank decomposition of matrix and weighted least squares theory.It is proved that the estimation result is equivalent to central fusion Kalman estimation result every moment every time,so it has the global optimality,which can obviously reduce computation burden and is convenient for real time use.Two simulation alternatives for a GPS target tracking system verify its functional equivalence, fastness and optimality.


It is a habitual topic of contemporary criticism that the Enlightenment has generated unprecedented systems of oppression, because of its belief in an externalized and objective truth. In this respect, in this article I investigate if it is possible to raise with all legitimacy, in accordance with Latour, that one of the many metaphysical origins of the twentieth-century world wars (and of the current «crash of civilizations») consists of this odd way with wich the West (throughout the so-called «modern age») sougth to pacify all conflicts by appeling to a single ad rational common world: the World of Science, of Technology, of the Market, Democracy...

Octamethylcyclotetrasiloxane (D4) and epoxy-contg. siloxane coupling agent were used as raw m-aterials to prep. epoxy-modified silicone emulsion with basic catalyst using emulsion polymn. method. The influences of polymn. factors on the polymn. rate, emulsion viscosity and emulsion transparency were measured, It indicated that polymn. reaction temp. at 60~70 ℃ and time for 9~11 h (monomer dropping for 2~4 h), catalyst amt. at 0.25%~0.75% based on the total wt of the emulsion, coupling agent amt. at 2%~5% of the D4 wt, emulsifier amt. 30%~40% of the D4 wt, and the phase ratio of 30%~45%. IR test confirmed the existence of the epoxy-modified silicone molecules. The emulsion stability was tested to demonstrate that it was a product with excellent stability.


The self‐consistent band structure of ZrB2 has been evaluated using the KKR method. It is noted that a large charge transfer is not necessary to explain many of the experimental results which can be understood in terms of the band structure and the bonding nature of the wave functions. X‐ray photoemission spectra and optical reflectance measurements are compared with the calculated density of states and joint density of states, respectively. The calculations are also discussed with reference to nuclear quadrupole experiments, Hall effect measurements, and the electronic specific heat. The similarities to intercalated graphite and related compounds are discussed and the strong bonding as reflected in the hardness and high melting point is considered.


has stated that &dquo; the biological treatment (of sewage) is usually more diflicult with septic tank effluent than with fresh sewage.&dquo; Other writers in Europe also appear to agree more or less with this dictum. From research work carried out in tropical a climate with a sewage derived from a vegetarian population, we have always held the opposite view. Experiments in India t on the nitrification of effluent appear to show that the contrary is the case, and that the more the breaking down action is allowed to go on in a septic tank, the easier it is to nitrify resulting effluent. Thus it was found that working with 3 septic tanks of 24 hours, 48 hours, and 72 hours capacity, the effluent from the last of these (72 hours rest) nitrified more rapidly than that from the other tanks; also that nitrites appeared from this e$iuent in, as a rule, about one-third of the length of time required by a dilution of crude sewage, giving the same 2 hours oxygen figure. As it was thought that the work quoted above was not absolutely convincing it was decided to try another series of experiments which would finally settle the question. In our laboratory we have made every morning an experimental sewage, which contains the faecal discharges of 10 men in a known quantity of water. This mixture only contains about 25 to 33 per cent. of the total urine in 24 hours. Taking two portions of this mixture, it was possible to put one sample through a septic tank and contact beds, and the other through small Dibdin slate beds and contact beds. The results obtained by this. work are obviously strictly comparable. Two small model septic tanks, that have been working in our laboratory for about 6 years without a break, were used in the experiments. The period of rest in the tank was 72 hours. The effluent then has two periods of 4 hours contact in two


Furnace Bottom Ash (FBA) is a by-product of coal-fired power generation plants. Few studies have focused on assessing the impact of using high volumes of FBA on lightweight aggregate concrete, especially on its dimensional stability and thermal insulation properties. In this study, normal weight coarse aggregate concrete (NAC) and lightweight coarse aggregate concrete (LWC) have been prepared. High volumes of FBA were used to replace natural fine aggregates to prepare the concrete mixes. Silica fume was used to mitigate the high permeability of concrete induced by porous aggregates incorporation. The compressive strength test results show that high strength LWC can be prepared with high volume FBA incorporation. The dimensional stability evaluation shows the linear relationship between FBA replacement ratio and autogenous shrinkage reduction. The internal curing effect of FBA aggregate has been investigated. The increased use of FBA in both NAC and LWC resulted in improved thermal insulation properties. The results indicate the potential of producing high performance lightweight aggregate concrete with high volume industrial by-products.


Abstract Complex contact relations between thin sills of the Adelaidean Cooee Dolerite and the enclosing flysch sediments (Burnie Formation) indicate emplacement of the sills into substantially uncompacted quasi‐liquid sediments very shortly after deposition. The sills are consequently coeval with the sediments rather than synchronous with the first phase of folding of the sediments (the Penguin Orogeny). The K/Ar date on the Cooee Dolerite, here revised as 725 ± 35 m.y. (J. Richards, pers. comm.), very probably provides an estimate of the age of the sediments, rather than the age of the orogeny. Age relationships of the Cooee Dolerite, its host sediments and their deformation proposed hitherto can no longer be regarded as settled. The Burnie Formation may be part of a passive continental margin to the Rocky Cape Block, which was deformed during the Cambrian as a result of subduction beneath the active margin of the Tyennan Block.

[Objective] To establish a simple method for identification of Callicarpa formosana Rolfe and other five kinds of Callicarpa bodinieri and provide a reference for quality control of Callicarpa medicine to ensure the safe and effective clinical application.[Method]Six kinds of Callicarpa leaves were identified by using characters identification,semi microscopic identification and microscopic identification methods. [Result]The morphological characteristics of different kinds of Callicarpa are similar. But there are some discernible differences in leaf shape,leaf apex,leaf base,leaf margin,thickness,surface hairy and color features. In the microscopic features,glandular hairs,non-glandular hairs and calcium oxalate crystals of different Callicarpa have obvious difference.[Conclusion]Characters identification method can identify several Callicarpa medicinal herbs,while some varieties are difficult to distinguish. But different kinds of Callicarpa can be identified by using semi microscopic identification and microscopic identification methods to observe the morphological features and distribution characteristics of glandular hairs,non-glandular hairs and crystals. An accurate,rapid and economical microscopic identification method is important to identify different Callicarpa leaves.


AbstractThe formulation of procyanidin gels based on cellulose derivatives is described. Type and optimal concentration of gelling agents were determined to obtain stable, limpid gels of satisfactory viscosity and pH compatible with anti-ulcer therapy.


Fourteen new alkyl 2-cyclopropylacrylates 1a−n with various substituents R1−R5 were synthesized from readily available precursors by applying standard transformations such as cyanohydrin formation from an aldehyde, alcoholysis to an α-hydroxycarboxylic ester, oxidation and Wittig methylenation of an α-oxocarboxylic ester. Overall yields ranged from 33 to 54%. A new method for the hydrolysis of dimethyl cyclopropanedicarboxylates to the corresponding half-esters was developed. The α-oxocarboxylates 7g−n were prepared by dirhodium tetraacetate catalyzed cyclopropanation of alkenes 8g−n with methyl or ethyl diazopyruvate in 32−58% yield. The monomers 1a−n were characterized by 1H, 13C NMR spectroscopy, mass spectrometry and elemental analysis. The radical homopolymerizations of 1a−n were carried out with 2,2′-azabisisobutyronitrile (AIBN) as initiator in chlorobenzene at 65 °C. The highest polymer yields were obtained in the polymerizations of 1f and 1h or 1k and 1l, i.e. from monomers with an annelated five- or six-membered ring. In the case of 1h and 1k, both the polymer yields (99 and 98%, respectively) and the glass transition temperatures (Tg) of 57 and 93 °C were significantly higher than those observed for the polymer from 1,1-bis(ethoxycarbonyl)-2-vinylcyclopropane (DECVCP), which was used as a benchmark for the monomer reactivities in the radical polymerizations of all the vinylcyclopropane derivatives 1a−n. The bicyclic monomers 1h and 1k also demonstrated drastically improved reactivities in the radical copolymerization with methyl methacrylate when compared to DECVCP. (© Wiley-VCH Verlag GmbH & Co.

Two-dimensional seismic responses of a concrete gravity dam under action of frequent and rare earthquakes were analyzed and influences of water level conditions on dynamic response of the dam were compared.The results show that under the frequent earthquake load the stress-strain relationship is basically in elastic deformation phase,while under the rare earthquake load,maximum seismic displacement occurs at the top of the dam,and with the increase of water level,displacement at top of the dam and dynamic stress at the dam heel decrease,and stress at the off slope of the dam changes slightly.


This paper contributes to the knowledge about how educational investments are allocated across siblings within the household. More specifically I focus on investigating whether there are signs of diversification, formal schooling being a risky investment. The data used is unusual in that it includes the head of household's risk preferences in addition to school-related and other information. This allows me to test whether older sibling's education is differently related to school start and school progress in households with differently risk-averse heads, something that should be expected if there is any household level diversification. I find this to be the case with regard to the probability of school entry, but not of school progress. And, the diversification mechanism is not strong enough to dominate forces creating positive sibling dependency in education. Trying to evaluate what causes the positive siblings' dependency I focus on economies of scale in education/sibling interaction and liquidity constraints and results points towards economies of scales being the important mechanism creating the positive siblings' dependency.


To the Editor: On measuring the success of an autologous blood donation program, Kruskall's goal was stated as being "...to maximize the use of autologous blood by patients undergoing such procedures and the efficiency with which the techniques are employed," and reference was made to a table of eight surgical or obstetrical procedures.' Success is the fulfillment of goals set in advance. But the goals must be right. With all due respect to Kruskall, I consider her goal myopic and very narrow in scope. In a democratic society where the balance between man and the state is tipped toward the individual, the right of the patient should take precedence. Implicit in Kruskall's goal is that we will not coerce patients to donate in order to maximize the use of autologous blood. A corollary should be that we will not deprive patients of the right to donate blood for autologous use, even if they have a statistically low chance of using it. The expectations of the patients should be the center of our goal. In general, the public does not have a clear perception of statistics; rather, individuals react to their emotions. Two actual incidents are representative. First, a patient was admitted through the emergency room for possible surgery. The physician ordered a transfusion, which used homologous blood. A daughter came to visit the patient and, on seeing the blood transfusion in process, removed the needle from the patient's arm. Despite all the counseling we could provide, the family insisted on untested directed donation. Second, a hematologist, a faculty member of an internationally respected medical school, was scheduled for elective disc operation. He knew, and was also told by the neurosurgeon, that the chances of blood transfusion were very remote, but still he wished to donate 2 units. In the first case, the statistics were not persuasive, and in the second case, they were not pertinent. There are many paradoxical views in the practice of transfusion medicine. Blood donation is a relatively harmless procedure, and we encourage millions of people to donate. Yet when it comes to our patients, we try to impose statistics and policies on them. Therefore, we have set the following goals for autologous donation: 1. Do no harm. 2. Inform and educate patients and physicians to the full extent of our knowledge, 3. Provide the service and ensure easy accessibility for all patients who may require a blood transfusion. 4. Let the patients decide for themselves. We may try to convince or persuade some patients, and we may even end by maximizing autologous blood utilization, but still it is the patient who decides. It is my experience that with an autologous program established around these goals, acceptance by the patients and physicians has been excellent.2 In conclusion, I believe that our goals should provide comfort and assurance to our patients that, barring economic constraints, "all will be done that can be done."


The new safety idea that takes mutual believe; mutual benefit, equality and cooperation as the core is a kind of new international political civilized idea gradually formed in the history course while the third generation leading collective of the Party headed by Jiang Zemin as the core are setting and carrying out the new international strategic police in the spirit of advancing with time Different from the old safety idea the new safety idea has much rich content and distinct time feature. It inherits and develops the strategic thought of Mao Zedong and Deng Xioping, adheres to and develops the basic principle of Marxist materialist dialectics and centrally embodies the important thought of "the three representatives". The new safety idea possesses the great strategic direct meaning in the respect of promoting international ant -terrorism and totally opening international safety cooperation , thus builds a historic contribution to making a good international peaceful environment for Chinese reform and open police and promoting the realization of "the three history tasks" ; meanwhile, it will exert still more active and profound influence on the establishment of new international politic and economic order in the 21st century and the long and stable international peaceful environment.


Purpose of the study: The present study diagnoses the vocabulary knowledge employed by ESL learners' through memory strategies. Schmiit's (1990) Taxonomy of Vocabulary Learning Strategies (VLS) questionnaire was adopted and administered to 93 ESL learners. In order to get authenticities about the ESL learners' memory strategies with vocabulary learning, semi-structured interviews were also conducted with 30 participants who completed the questionnaire. The result exposed the subsequent array of memory strategies used by ESL learners from the most frequent to the least frequent strategies, particularly findings revealed that 'Use new word in sentences', 'Study word with a pictorial representation of its Meaning', 'Connect word to a personal experience' are most popular whereas 'Use scales for gradable adjectives', 'Relating word to unrelated items (Peg method)' were least used memory strategies.
Methodology: Schmitt's Vocabulary Learning Strategies Questionnaire (VLSQ) (1997) was favored to diagnose the vocabulary knowledge through memory strategies of 93 ESL learners. Initially the responses were collected through Google Forms. Additionally, 30 ESL learners were randomly selected for interviews in accordance to reassure participants' comprehension of the subject matters.
Main Findings: The study finds effective result among 93 ESL learners in acquiring vocabulary knowledge while using memory strategies with the assistance of technological modalities. It also listed the most frequent and least frequent use of memory strategies in Schmitt's Vocabulary Learning Strategies Questionnaire (VLSQ) (1997).
Applications of this study: The present study is conducted in English Language Laboratory, where ESL learners' can be benefitted and the learners can use these memory strategies while learning a new vocabulary when encountering a word.
Novelty/Originality of this study: The existing technological modalities will assist the learners to correlate more effectively. Subject and language experts in the field can design the instructional materials and tools to assist ESL learners to improve vocabulary knowledge through memory strategies.


Lasing at 482 nm is observed in Tm/sup 3+/-doped ZBLAN glass fiber pumped with single-mode InP semiconductor diode lasers. Up to 5 mW of 482 nm light is obtained with <40 mW of absorbed pump power from a single 1135 nm pump diode laser. The optimum pump wavelength is measured to be 1135-1340 nm. More efficient laser operation is observed in fiber with 2500 ppm Tm/sup 3+/ compared to 1000 ppm Tm/sup 3+/ because of the reduced length of the fiber laser cavity possible with increased doping. Improved slope efficiencies are also demonstrated when the fiber laser is co-pumped with up to 5 mW from a 1220 nm diode laser. The relative intensity noise (RIN) of the fiber laser displays a maximum of -90 dB/Hz at relaxation oscillation frequencies of a few tens of kHz. The measurement of RIN is limited by shot-noise of -152 dB/Hz above 2 MHz. At higher frequencies, self mode-locking was observed in the fiber laser, which may indicate the existence of saturable absorbers in the fiber core. The presence of such bleachable absorbers is indicated by the observed increase in threshold after upconversion lasing at 482 mm.


The Federal Customs Service of Russia declares the improvement in the quality of customs administration and reduction of the administrative burden on business through automation of registration and release of customs declarations filed by low-risk foreign trade operators (80% by 2020), enhancing foreign trade operator categorization by risk level. However, the main improvements in customs administration, enshrined in the government plans, retain the basic technologies and business processes unchanged, and thus preserve the main problems. As a result, Russia lags behind developed and some developing countries in international customs ratings. The article considers the most urgent problems in the customs sphere and presents proposals for their solution. We examine the problems of international transit related to the harmonization of customs documents and financial guarantees with countries involved in transit operations. The use of primary documents by economic operators, including the use of foreign electronic data, has been considered for electronic document circulation. With regard to non-tariff measures, the possibility of transferring control over compliance with technical regulation measures to domestic circulation is addressed. Another important issue is the possibility of introducing general financial guarantees in amounts adequate to non-payment risks. Big data involvement (producers, persons involved in the supply chain, goods turnover in the territory etc.) for risk management system development in the customs sphere is discussed. Conditions for the creation of consignment warehouses in Russia, for Internet shops in particular, are regarded as one of the important directions of foreign trade infrastructure development.


Carbon sequestration potential of Eucalyptus camaldulensis Dehnh and Acacia salicina Lindl planted in 1980 was studied at the age of 30 years in the elevation plain areas of Iran. Two station of this plantation in province were selected the sample plots and the diameter at breast height of all trees was measured. At least, there trees from each diameter class were randomly selected and cut and different parts of the trees including, trunks, branches and leaves were separately weighed. The main roots of one tree from each diameter class were also nine collected and weighed. To estimate the man weight of litter per hectare, 40 sample plots of one square meter were randomly chosen and the amount of litter was determined. The percent of organic carbon in leaves and litter was also calculated in the laboratory. The amount of carbon sequestrated in the soil of plantation area was calculated and compared with control. This study showed that the amount of carbon sequestrated by E.camaldulensis in the productive site and poor site was about 8.2 and 1.73 ton hayear , respectively. On the other hand , for Acacia salicina in the poor site of this figure was 2.1 ton/ha in year. The highest the amount of sequestrated carbon in E.camaldulensis was in 30 centimeter diameter class. This figure for Acacia was in 25 centimeter diameter class. The amount of carbon sequestrated in different parts of the tree showed a significant difference at 0.01 also in E.camaldulensis , there was a significant difference in the amount of carbon sequestration between the suitable and poor sites. This study showed that there is a great potential of plantations in Fars province and similar areas of the country. This plantation will maintain suitable green areas and belts and produce wood materials for consumption in several ways. Forever planting trees will lead to the reduction of co2 in atmosphere which reduces the greenhouse effect , a program which is university promoted and partially sponsored by united nations and some industrialized countries .

Deterioration rate may be constant or varies with time. In real life time dependent deterioration is observed in many products like fruits, bakery products, milk products etc. Generally deterioration rate increases as the time passes. In this paper we present an inventory model for the trapezoidal type demand function and time dependent deterioration rate. Demand rate depends on time as well as price. Shortages are allowed with partial backlogging. In order to illustrate solution procedure numerical examples and sensitivity analysis have been demonstrated.


Generations journal has been published for nearly forty years, yet this Fall 2016 issue is the first to focus on oral health. In the early 1970s, more than 55 percent of older adults were completely edentulous (without teeth). Since then, one of the goals of the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC) has been to reduce the edentulous rate to only 10 percent. As the number of elders with teeth has increased, oral health professionals have had to learn more about geriatrics. Unfortunately, other health and health service professions have not learned more about oral health.There is a good reason for this: our healthcare culture sees the mouth as "only a tooth" instead of as an integral part of the body. Moreover, if oral health had been included in overall health insurance all these years, it would have helped broaden the view that oral healthcare is a necessary component of primary care. This healthcare culture is largely unaware that many low-income elders, who are often, though not always, institutionalized, have died from untreated oral disease.How did we get to this point?A Long Journey: Integrating Oral Care with Overall HealthcareIn 1988, then-Surgeon General C. Everett Koop held the Surgeon General's Workshop on Health Promotion and Aging for 180 invited attendees, yet only seventeen participants focused on oral health. The Surgeon General had already held eight workshops, and this was the first to include oral health as a topic. The group made several recommendations in the areas of education, service, research, and policy, and those relevant to this issue of Generations are included in the sidebar on page 8 (HHS and AOA, 1988).These recommendations were made twentyeight years ago, and while there has been some improvement in following a few of them, and good progress made with others, there has been little to no improvement in seven of the recommendations listed in this article.Why has progress been so minimal?Two years after the workshop report was released, leaders in dental education asked the Institute of Medicine (IOM) to conduct an independent assessment of dental education. Many dental schools had closed, and they were worried about the future of dental education. The IOM conducted an extensive five-year study and in 1995 released Dental Education at the Crossroads: Challenges and Change. The sidebar on this page lists selected key policy and strategic principles from this report (Field, 1995).These principles are covered in many of the articles in this issue of Generations. See Yellowitz's article on page 60; Ettinger and Cowen's article, page 66; and Roberts and colleagues' article, page 79; these describe distinctive programs to build and train the professional workforce. Also see articles that discuss innovative models to deliver oral care for older adults: Becerra and Nguyen, page 100; Chavez and Lederman, page 104; and Wiseman, page 108.The IOM study committee envisioned an ideal future for dentistry, stating five key elements:First, dentistry will and should become more closely integrated with medicine and the health care system on all levels: education, research, and patient care... Second, to prepare their students and their schools for change, dental educators will need to teach and display desirable models of clinical practice. Third, securing the resources essential for educational improvement and, indeed, survival will require that dental schools demonstrate their contributions to their parent universities, academic health centers, and communities... dentistry cannot afford isolation . . . Fourth, dental leaders should cooperate to reform accreditation and licensingpractices so that they support rather than obstruct the profession's evolution ... Fifth, continued testing of alternative models of education, practice, and performance assessment for dentists and allied dental professionals is necessary to prepare the dental community-educators, practitioners, regulators, and policymakers-for an uncertain future. …


In Karnataka crop productivity trends have been below the Indian average for most of the crops and far below their potential yield, even after Karnataka's fertile land and water resources. About 84.97 per cent of the farmers are small and marginal in India having only 44.31 per cent of the total operational holdings. The average size of the holding is 0.83 ha (Singh et al., 2010). With the average size of land holdings shrinking as a result of increasing fragmentation, many marginal farms are becoming economically non-viable and oriented towards subsistence. Due to failure of monsoon, the farmers are forced to judicious mix up of agricultural enterprises like dairy, poultry, poultry birds, fishery, sericulture, apiculture etc., suited to their agro-climatic and socio-economic condition and largely dependent on the farm size. To overcome the problems of small resource poor farmers, diverse and risk prone environments has led to the development of a more holistic, resource based, client oriented and interacting approach, popularly known as integrated farming system. Integrated farming system is a reliable way of obtaining high productivity with Abstract : A field experiment was conducted at Main Agricultural Research Station (MARS), Raichur during 2012-14 to study resource recycling and management from different IFS models in NE Karnataka. Different combination of crops, animals, fishes and birds were examined in form of seven integrated farming systems (IFS) models. Among different IFS models crop + cow + goat + poultry birds + fish (F 7 ) emerged as the best integrated farming system in terms of resource recycling, resource management and nutrient budgeting. The waste material/by products of crops and animals were recycled and used as inputs for other components of integrated farming system. The F 7 system (19,122 and 20,623 kg ha during 2012-13 and 2013-14, respectively) added highest amount of organic residues in both the years which is closely followed by F 5 system (18,368 and 19,614 kg ha during 2012-13 and 2013-14, respectively). Quantity of N, P and K added and nutrient budgeting varied between IFS models.


To solve the inverse kinematics problem, we obtain with little effort a reduced and complete set of equations by a conve nient choice of end-effector frame and application of rotation orthogonality. This approach does not require computation of the forward kinematics and can be used with manipulators of any geometry, although it is most efficient when applied to orthogonal manipulators, a class of robot arms defined in this paper. For manipulators requiring numerical techniques, but for which knowledge of one joint variable allows closed- form solutions of the remaining joint variables, an iterative inverse kinematic method, simple and fast enough to be suitable for real-time manipulator control, has been devel oped. The concepts and techniques presented in this paper are illustrated with two examples. The iterative method devel oped here performs a kinematic inversion of a 6-degree-of- freedom manipulator with no closed-form solutions in less than 30 ms using a desktop computer, an order of magnitude faster than times found in the literature.


This study, the third in a series of three, draws on a broader Norwegian research project exploring the phenomenon of support for young persons with mental health issues. The aim was to explore and explicate the sense of "nourishing communion", as a somewhat neglected aspect of support. Fourteen Norwegian young adults, aged 18-25, were interviewed about their experiences of support. Data was analyzed using van Manen's hermeneutic-phenomenological approach to open up possible meanings of how nourishing communion is concretely lived. Analysis was supplemented by in-depth reflexive dialogues between the first and second author, which fostered a nourishing communion akin to the processes and dimensions of our phenomenon of interest. Findings highlight five intertwined existential themes: a) trusting the other to hold vulnerability safely; b) flourishing in mutual participation; c) acceptance in a felt togetherness; d) feeling found and received; and e) feeling an attuned resonance. The notion of "nourishing communion" as a significant but neglected element of support challenges current practice, suggesting the need for a different approach to collaboration with young persons and their networks. From the perspectives both of individual professional engagement and of policy making, there is a need for further exploration of how young persons might be supported to create and maintain a broader range of nourishing relationships.


By means of computer calculations, according to the RRITA2D's program, there was made an investigation of the beam's behavior after passing the reverse area with a linear change of the magnetic field. On the basis of these studies, it is given a technique for determining the parameters of the reverse magnetic field to obtain an electron beam with minimal pulsations. This very technique has been applied to the six-resonator klystron. It is done to improve beam's current flow with the reverse of magnetic field between third and fourth resonators. As a result, position selection of reverse on the plot of pulsation recession allowed to improve electron's current flow from 60 to 100% at numerical mode and to 99,5% at experimental units.


As scientific ontologies are integrated into the publishing workflow many enhancements to scientific communication will be possible, including improved support for text mining, information extraction, and literature-based discovery. One enhancement that is not so obvious, but will almost certainly have profound effects on the daily lives of working scientists, is support for the long-standing practice of strategic reading.


. In this paper, we analyze lattice linearity of multiplication and modulo operations. We demonstrate that these operations are lattice linear and the parallel processing algorithms that we study for both these operations are able to exploit the lattice linearity of their respective problems. This implies that these algorithms can be implemented in asynchronous environments, where the nodes are allowed to read old information from each other and are still guaranteed to converge within the same time complexity. These algorithms also exhibit properties similar to snap-stabilization, i.e


Abstract : The intensity of the principal emission band of zincdiffused GaAs p-n junctions with about 2 x 10 to the 17th power cu cm in the n-type region is proportional to exp(qV/kT). The energy of the peak of this band is independent of the forward bias V for these diodes. If the principal emission band results from the recombination of electrons that diffuse across the junction, and if nonradiative recombination is by far the more probable, then the intensity of the principal emission band is proportional to tau exp(qV/kT), where tau is the minority carrier lifetime in the p-type region. This dependence on tau comes, in part, from the gradient of acceptor concentration in the p-type region. Irradiation with 2-MeV electrons decreases the intensity and increases the forward current at a given voltage. The decrease in intensity is consistent with the above model if 1/tau increases linearly with integrated flux. The increase in current is greater for larger bias, suggesting that only the diffusion component of current is affected by irradiation. (Author)


Ultrafast electron beam x-ray computed tomography (UFXCT) has in recent years become an indispensable tool for multiphase flow studies. An essential feature of this technique is fast cross-sectional imaging in two distinct planes. Both the spatial location of focal spot path and detectors as well as the angular scanning range in UFXCT differ from that of conventional x-ray CT systems. This brings in a spatial dependence in axial scanning position and resolution. In this paper, we present an analysis of this problem, which results in an improved description of the location and shape of the imaging regions, a more accurate map of the distance between the imaging planes and, finally, a higher precision in the determination of axial structure velocities. The benefit of this improved approach is exemplarily demonstrated for a two-phase pipe flow around an obstacle.


Background: Motivational interviewing is a patient-centered directive approach to enhance intrinsic motivation to behavioral change by helping patients explore and resolve ambivalence between the desired behavior and their actual behavior. This study aimed to assess the effects of a motivational interviewing as Psychiatric nursing program on smoking cessation among smoker patients with heart disease to increase motivation and promote change. Research hypothesis: The motivational interviewing program will have a positive effect on smoking cessation among smokers' patients with heart disease. Design: quasi-experimental design (one group pre-test post-test design) was utilized to achieve the aim of the study. Setting:-The study was conducted at outpatients' clinic in Benha University Hospital. Subjects: Purposive sampling of the present study were 40 patients with heart disease. Tool of Data Collection: The tool was divided into four parts: 1 st part: Socio-demographic data 2nd part: Fagerstrom Test for Nicotine Dependence (FTND) questionnaire (1991) . 3rd part: Readiness to Change Questionnaire was adopted from Rollnick et al., (1992). 4th part: Assess the need to quit smoking SCAN adopted from Zeldman et al.,(2004) .

One of the important leading indicators that show the current state of the country's economic cycle, its prospects in the near future and generally characterize the country's business climate is the business confidence index (BCI). In this paper a forecast of the business confidence index is built using neural network technology using the example of the four European countries (Germany, Hungary, Poland, Slovenia).Forecasting was carried out taking into account economic indicators that characterize the socio-economic situation in the country. The selected economic indicators based on correlation analysis and have significant relationship with the business confidence index. For forecasting, the quarterly values of economic indicators for the last 12 years (2007-2018) were taken. Also the accuracy of the obtained forecasts was also assessed and the trends of the business confidence index development are established. It was found that the accuracy of the obtained forecasts is high. It has been proven that level of the BCI in the next period will decrease by 0.41% in Germany, by 1.05% in Hungary, by 0.99% in Poland and will remain unchanged in Slovenia. The obtained forecasting results make it possible to predict changes in the business climate in a country earlier than other macroeconomic indicators. The perspectives of the research are the elaboration of a country's business climate development strategies, based on the results of the BCI forecasting. Keywords—business climate, business confidence index, correlation analysis, socio-economic indicators, neural network modelling

This paper outlines some of the reasons behind the development of Japan's high performance in bridge design and construction, and emphasises current trends and projects which illustrate the current state of Japan's bridge-building industry. In preindustrial times, many bridges of aesthetic value and fine craftsmanship were built in Japan. Then rather heavy-looking unspectacular bridges were designed and built, using imported construction techniques. During recent years, Japan has been producing bridges of artistic merit, with technology refined or developed indigenously. Two factors have been especially important for Japanese bridge development: (1) the almost limitless potential for bridge building provided by Japan's natural geography; and (2) Japan's outstanding qualities of human endeavour and enterprise. Most developments in design have been evolutionary rather than revolutionary. However, some more recently completed bridges have interesting features, largely due to increased emphasis on: (1) aesthetics; (2) attention to details; (3) construction aspects; and (4) new seismic techniques. Innovative bridges include two unusual curved cable-stay bridges and the world's first 'extradosed' cable-stay bridge. Prospects for the future of Japanese bridges are discussed briefly, and seem good.

This paper proposes a Bayesian approach to image recognition based on separable lattice hidden Markov models (SL-HMMs). The geometric variations of the object to be recognized, e.g., size, location, and rotation, are an essential problem in image recognition. SL-HMMs, which have been proposed to reduce the effect of geometric variations, can perform elastic matching both horizontally and vertically. This makes it possible to model not only invariances to the size and location of the object but also nonlinear warping in both dimensions. The maximum likelihood (ML) method has been used in training SL-HMMs. However, in some image recognition tasks, it is difficult to acquire sufficient training data, and the ML method suffers from the over-fitting problem when there is insufficient training data. This study aims to accurately estimate SL-HMMs using the maximum a posteriori (MAP) and variational Bayesian (VB) methods. The MAP and VB methods can utilize prior distributions representing useful prior information, and the VB method is expected to obtain high generalization ability by marginalization of model parameters. Furthermore, to overcome the local maximum problem in the MAP and VB methods, the deterministic annealing expectation maximization algorithm is applied for training SL-HMMs. Face recognition experiments performed on the XM2VTS database indicated that the proposed method offers significantly improved image recognition performance. Additionally, comparative experiment results showed that the proposed method was more robust to geometric variations than convolutional neural networks. key words: image recognition, hidden Markov models, separable lattice hidden Markov models, Bayesian approach, deterministic annealing

It is possible to develop some important ideas around the issue of the Venezuelan government's decision to close its border with Colombia, as a solution to the problem of shortage of basic basket products in the Venezuelan market, an analysis carried out from the perspective of governance and Cross-border cooperation, which has revealed the socio-economic situation in the so-called border areas that comprise, in our case, the territories shared by Colombia and Venezuela.


This study was carried out to investigate the effects of hydrolysis ratio on the structure and adsorption properties of porous starch. The starches with different hydrolysis ratios were prepared by enzymolysis (combination of α-amylase and glucoamylase), and its adsorption capacity was evaluated by using methylene blue (MB) and soybean oil as adsorption objects. The results suggest that crystallinity, specific surface area and adsorption capacity of porous starch were gradually improved with the increase of hydrolysis degree. The crystallinity of native starch was increased by enzymolysis from 28.43±0.23% to 34.70±0.69%, and the specific surface area was increased from 0.58±0.002 m2/g to 1.82±0.014 m2/g. Moreover, the adsorption capacity toward (MB) was increased from 2.88 mg/g to 3.87 mg/g at 25°C, which was accurately described by the pseudo-first-order kinetic model, and the oil absorption ratio was also greatly improved from 23.2±0.16% to 76.1±0.11%. Thus, the properties of porous starch can be adjusted by controlling the hydrolysis ratio to meet different needs in the market.

Global preserving manifold learning algorithms are mainly based on preserving global geometric properties between high-dimensional observed space and intrinsic low-dimensional manifold.This paper compares in detail the characters and interre-lations of several classical manifold learning algorithms based on preserving global properties.Some advantages and shortcomings of these algorithms are shown.Experimental results demonstrate the differences of these algorithms about intrinsic dimension and intrinsic low-dimensional manifold.Finally,several new research directions of manifold learning are proposed.


The main drawback of reluctance machines is a high torque ripple, due to the interaction between the stator magneto-motive force and the rotor structure. Adopting a rotor configuration characterized by several flux barriers per pole, there is a high influence of the rotor geometry on the machine performance, in terms of both average torque and ripple. An optimization is often required to determine the optimal rotor geometry so as to achieve a high and smooth torque. Then, the geometry determined above should guarantee good performance for various operating points (i.e., changing the current amplitude and phase), as well as for small variations of the geometry. This paper investigates this aspect, showing the results of optimizations carried out on various machines. The impact of the geometry parameters is taken into account and the sensitivity of the optimal solution to the geometry variation is pointed out. The paper highlights the difficulty to get a robust geometry as far as the torque ripple reduction is concerned. Finally, a few experimental results on a Synchronous Reluctance motor prototype will be presented, compared with Finite Element Analysis simulations for validation.


The key to the future of any society lies in the transmission of its culture and worldview to succeeding generations. The socialization of children, through education, shapes all aspects of identity, instilling knowledge of the group's language, history, traditions, behavior, and spiritual beliefs (Barman, Hebert, & McCaskill, 1986, p. 150). Indigenous peoples are not a homogenous group: there are cultural, historic and economic differences among them (Aikman 1995, McAlphine, et al. 1996; Semali, 1999). However, there are commonalities that they share, such as their intimate relationship with the land, environment and the cosmological world. In addition, they share the pain of loosing their ancestral lands to the colonizers as this is the major thing that connects them to their inner being, the spirit world and Mother Earth. Hence, "when they loose their land, they loose their languages, culture, social and political systems" (Reyhner 1996: 7). Hayden Burgess of the World Council of Indigenous Peoples says: "Next to shooting indigenous peoples, the surest way to kill us is to separate us from our part of the Earth. Once separated, we will either perish in body and soul and our minds and spirits will be altered so that we end up mimicking foreign ways…" (Burger 1990: 122). To the West, land belongs to the people, but, according to the World Council of Indigenous Peoples, people belong to the land (Almeida, 1998).

The activity,deactivation,activity regeneration of amorphous TiO2/WO3 films were studied via photocatalytic oxidation of methyl blue.The photodegradation ratio of methyl blue was 93.8% by fresh TiO2/WO3 films.Having been used for six times,the photodegradation ratio was still higher than 85%.For the deactivated films after reused for nine times,four methods were attempted to regenerate the activity,soaking in water or ethanol for 30 minutes and ultrasonic treatment in distilled water or ethanol for 30 minutes,with which the photodegradation ratio could be resumed from 10.3% to 23.2%,28.3%,79.2% and 90.5% respectively.


126. After logarithms and exponential quantities have been considered, circular arcs and the sines and cosines of these must be considered; not only because they constitute another kind of transcending quantity, but also because of the logarithms and exponentials of these that arise when they are involved with imaginary quantities, which will become clearer below. Therefore we may put the radius of the circle or the whole sine to be and it is clear enough that the periphery of this circle cannot be expressed exactly in rational numbers; but by approximations the semi–circumference of this circle has been found to be 1 


This invention relates to a method for producing L-aspartic acid comprising treating an ammonium fumarate Solution with aspartase to generate an ammonium L-aspartate Solu tion; adding fumaric acid to the Solution; and then crystal lizing L-aspartic acid from the Solution, wherein fumaric acid is added to the ammonium L-aspartate Solution after the Solution has been heated to 50 to 130 C. in an amount 0.4 to 0.8 times the total amount of fumarate and the L-aspartate contained therein in terms of mole, and the resultant mixture is once turned into a homogeneous Solution by applying thereto a Shearing force, and then L-aspartic acid is depos ited therefrom, or wherein the Solution is cooled at a rate of 0.1-5.

Considering the high proportion spend of beef in the budget of Chilean households, a survey carried out that looked at the habits, consumption preferences and knowledge about the use of beef among supermarket clients in Temuco, IX Region of Chile. The existence of differences between various segments of the population was also looked at. The survey was carried out in eleven supermarkets, with a sample of 260 individuals, stratified by sex, socio-economic stratum and age. Beef was preferred to chicken and pork. The individuals who made the decision and purchased the beef were generally women. It was most common for beef to be purchased in cuts, with a frequency of three times per week, and in quantities of between 1 and 2 kg at each purchase. Approximately 50% displayed a low level of knowledge with regard to the uses of the various cuts. Differences in habits, preferences and degree of knowledge of the culinary uses of beef were detected according to the sex and socio-economic stratum of the consumer. Key word: Beef, demand, segmentation.


The study presents a methodology for detection of pedestrian presence at road crossings. It is based on image processing and a recognition background pattern. For each camera image is applied a filter in order to exclude pedestrians outside the waiting enclosure from affecting the system's decisions. Next, the object is converted to black and white format and is divided into sections. Each section is compared with the corresponding section from the recognition pattern pixel-by-pixel. The relative error between the two images is then compared to a critical value, and a decision is made. The analysis of the images by sections reduces the influence of potential vibrations, thus significantly increasing the probability for correct recognitions.


At the present stage, the most important socio-psychological resource for improving the inclusive education quality is the extension of personal communication experience of disabled people and people without disabilities. This article analyzes the problems and features of the inclusive education quality in the transforming society culture. The work considers the ways the parents of children with disabilities see the improving of the inclusive education quality. The research distinguishes the following ways to improve the inclusive education quality in accordance with the view of parents of children with disabilities: society public education, that should be unobtrusive, but at the same time form tolerant attitudes; human resources are the key factors for improving the inclusive education quality; the need for teachers to take courses based on a social approach to disability, not on medical terminology; the need to introduce a tutoring system in inclusive classrooms; the need to develop all the measures to create an accessible environment, including the information environment, only after monitoring the educational needs of disabled children. The parents of children with disabilities emphasize the extension of personal communication experience of people with disabilities and without them as the most important socio-psychological resource for improving the inclusive education quality.


We use magnetic collapse models to place some constraints on the formation and angular momentum evolution of circumstellar disks that are embedded in magnetized cloud cores. Previous models have shown that the early evolution of a magnetized cloud core is governed by ambipolar diffusion and magnetic braking, and that the core takes the form of a nonequilibrium flattened envelope that ultimately collapses dynamically to form a protostar. In this paper, we focus on the inner centrifugally supported disk, which is formed only after a central protostar exists, and grows by dynamical accretion from the flattened envelope. We estimate a centrifugal radius for the collapse of mass shells within a rotating, magnetized cloud core. The centrifugal radius of the inner disk is related to its mass through two important parameters characterizing the background medium: the background rotation rate Ωb and the background magnetic field strength Bref. We also revisit the issue of how rapidly mass is deposited onto the disk (the mass accretion rate) and use several recent models to comment upon the likely outcome in magnetized cores. Our model predicts that a significant centrifugal disk (much larger than a stellar radius) will be present in the very early (class 0) stage of protostellar evolution. Additionally, we derive an upper limit for the disk radius as it evolves owing to internal torques, under the assumption that the star-disk system conserves its mass and angular momentum even while most of the mass is transferred to a central star.


The article is dedicated to the review of the origin and promotion of the "free" excursions service in Ukraine as well as to the change of attitude towards them during the russian military aggression. The terminological confusion that arises among the Ukrainian consumers with the use of the term Free Walking Tours are indicated in the article. This term is considered in Ukrainian realities through the prism of such concepts as "free", "unpaid", "open", "volunteer", although in global practice such excursions are provided exclusively "for tips". An analysis of the strategies of sites advertising Free Walking Tours is presented, the most popular of them and those containing information about similar services on the Ukrainian market are identified. The degree of the Ukrainian tour guides inclusion in this information space is determined. The possibilities of collaboration in creating an excursion service in foreign languages are shown. The positive effect of the fact that the price of this service is determined by consumers is shown due to the fact that it has a great psychological effect with a low degree of expectation. Also, this factor affects the promotion of a certain destination, the degree of feedback on the tour guide's work and the impression of the trip. The positive impact of free excursions on the psychological relief of internally displaced persons in the conditions of war in Ukraine is analyzed. It is noted that this format of the excursion is the best format in the conditions of economic recession and exit from the crisis. The conclusions presented in the article will provide an opportunity to understand the strategy of promoting the Free Walking Tours service for the Ukrainian consumer and to overcome the terminological discrepancy arising in the advertising of "free" excursions "for a tip" for the Ukrainian consumer. The presence of a wide network of international resources for advertising such services is an opportunity to improve and diversify this service with Ukrainian tour guides in foreign languages.

The authors consider a simple medium access control technique for a slotted multiple access channel in a mixed traffic environment. The aim is to optimize the multiple access techniques so that the maximum delay constraints are satisfied. Steady-state expressions for channel throughput, average packet delay, and average packet loss rate are developed for fixed and adaptive retransmission schemes. Using adaptive retransmission techniques, significant improvement in performance can be obtained in the high-throughput operating region. The performance does not change significantly with the actual mix (%) of real-time and nonreal-time traffic. The analysis methodology used can be easily extended to include additional classes of traffic. The access control techniques discussed are applicable to a variety of communications applications, including low-earth-orbit satellite communication systems.<<ETX>>


Plant roots, microbial bodies and derived compounds are likely the main source of carbon sequestered and stabilized in soil [1]. Most root carbon is decomposed to CO 2 , and the remainder typically undergoes multiple microbial transformations before it is stabilized. The characteristics of the resulting plant and microbially derived organic compounds (lipids, proteins, polysaccharides, lignins, amino acids) are likely to interact differently with soils mineral phases in soils, which will determine how much carbon remains in soil based on the reactivity of their component molecular groups (carboxylic acids, amines, aromatic rings) Advancing our understanding of soil organic matter dynamics requires disentangling the complex interactions between soil mineral surfaces and decomposed organic compounds, and soil microbial activity/biomass. and mineral cutting-edge technologies: soil analytical for analysis


The care of critically ill children has received much attention in the past decade, and many of the recommendations from reports relating to the provision of paediatric intensive care have been addressed. In comparison, high dependency care has received less attention. This level of care is often provided on 'general' children's wards, yet its impact on nursing staff and care delivery have received little attention. This article presents a study which explores nurses' experiences of providing high dependency care on children's wards using focus groups. Following analysis, six categories emerged: definitions and perceptions of high dependency care; having a high dependency unit; problems in district general hospitals; the skills needed for high dependency care; team working; and staffing for high dependency care. These findings have implications for current clinical, managerial and educational practice and for future developments in the field of high dependency care for children.


INTRODUCTION
Sugammadex is a cyclodextrin that reverses neuromuscular blockade, especially of rocuronium. The occurrence of anaphylaxis produced by its use is of 1:1000 and 1:20000; it is observed mainly in subjects of Asian origin.

CASE REPORT
A 9-year-old boy of Asian origin who, after the administration of sugammadex, immediately manifested an episode of anaphylaxis, which was reverted by using adrenaline and antihistamines. The serum tryptase at two hours was 27.7 μg/L; at 6 weeks, it was 3 μ/L. The sugammadex 100 mg/mL skin test was positive. The basophil activation test was positive with sugammadex 20 mg/mL.

CONCLUSION
The temporal relationship between the administration of the drug, the clinical manifestations, the elevation of tryptase, and the diagnostic tests performed, disclosed the episode of anaphylaxis associated with hypersensitivity to sugammadex.


A semiempirical method for computing atomic and ionic wave functions is described. The method uses a one-electron potential obtained from a scaled Thomas-Fermi ionic charge distribution. The scale factors are chosen to make the one-electron binding energies agree with experimental ionization potentials. A number of oscillator strengths have been evaluated and are found to agree well with results of alternative methods of calculation. The method has a wider range of applicability than that of Bates and Damgaard, and calculations are much shorter than those using the self-consistent-field methods.


Apple replant disease (ARD), caused by a complex of soilborne pathogens, negatively impacts tree health and productivity in new orchard plantings at sites previously planted to apple. Use of new disease-tolerant apple rootstock genotypes may diminish growth-limiting effects of ARD; however, the influence of rootstock genotype on modulating the rhizosphere and endophytic microbiome to enable ARD tolerance is not fully understood. Composition of the rhizosphere and root endophytic microbiomes was characterized across a diversity of apple rootstock genotypes. A series of tolerant (G.210, G.41, G.890, and G.935) and susceptible (M.26 and M.9) rootstock cultivars were consecutively planted into orchard replant soil containing a known pathogen complex. Amplicon sequencing was used to determine simultaneously the presence of a broad taxonomic range of organisms and their relative abundance. Microbial communities exhibited significant differences in composition between the rhizosphere and endophytic environments in terms of species diversity, content, and abundance. Significant differences in composition of the endophytic and rhizosphere microbiomes were observed between rootstock genotypes. Among rootstock endophytic fungal communities, rootstock G.890 samples consistently harbored the highest percentage of arbuscular mycorrhizal fungal species (>5% of total). Ilyonectria spp., which may function as a pathogen of apple, were detected at high relative abundance in the endosphere of all genotypes, with the highest relative abundance in M.26. These results provide further insight into rhizosphere and endophytic microbial communities of apple rootstocks, which could be exploited or manipulated to improve tree fruit agricultural management practices with respect to plant nutrition and disease control.


Acoustic impedance in carbonates is influenced by factors such as porosity, pore structure/fracture, fluid content, and lithology. Occurrence of moldic and vuggy pores, fractures and other pore structures due to diagenesis in carbonate rocks can greatly complicate the relationships between impedance and porosity. Using a frame flexibility factor (γ) derived from a poroelastic model to characterize pore structure in reservoir rocks, we find that its product with porosity can result in a much better correlation with sonic velocity (Vp = A − B ∗ ϕ ∗ γ) and acoustic impedance (AI = C − D ∗ ϕ ∗ γ), where A, B, C and D is 6.60, 0.03, 18.3 and 0.09, respectively for the deep low-porosity carbonate reservoir studied in this paper. These new relationships can also be useful in improving seismic inversion of ultra-deep hydrocarbon reservoirs in other similar environments.


Centralized drug procurement is an important measure to alleviate the high cost of drugs for the masses. However, due to the difficulties in platform interaction, low transparency, privacy disclosure and other problems of centralized drug procurement, the efficiency of drug circulation is low and violations emerge in an endless stream. Blockchain technology is characterized by decentralization, tamper-proof, autonomy, etc. Combined with the features of numerous participants in centralized drug procurement and large amount of data processing, a framework for centralized drug procurement based on super ledger is built, and identity registration chain code, price negotiation chain code, and contract performance chain code are designed to realize centralized drug procurement autonomy, openness, transparency, and traceability. It aims to improve centralized drug procurement and ensure transparency and accountability throughout the drug supply chain in order to maximize the effect of lower prices brought about by healthcare reform.


The screener is widely use in metallurgy, mine, etc. Now the low productivity ratio and low efficiency influence a lot to the working of factories. In this paper, we analyze the motion of object on the screener, and then build the mathematical model to maximize the productivity ratio. Take the example of straight Line vibration screeners with mode ZKB. After maximizing with our method, the result shows that our method increases 21% in the productivity ratio, and the chance of object touching the screen holes increases 45%. This paper provides an effective method for the optimal design of screener in future.The results of this study can also be applied directly to enterprise product design.
