Bush thinning or clearing rangeland management practice in Borana rangelands considered to have a high potential to improve rangeland productivities and soil conditions, yet few studies have quantified the impacts of bush management on herbaceous plants species diversity, biomass and soil Organic Carbon and Nitrogen contents. This study was conducted in Yaballo (Hara-woyu Kebele) and Taltale (Sarite kebele) Woreda of Borana zone, to evaluate the impacts of bush management (thinning) on herbaceous plant species composition, diversity, biomass and some selected soil physicochemical properties. Data were collected from bush thinned and bush encroached rangeland management classes at both sites. Sampling plots were placed systematically along the geographic gradient in both of the rangeland management classes at both study sites. Within all plots, herbaceous plants were identified and clipped to the ground, collected and oven-dried to determine biomass. Herbaceous plant species, diversity, biomass and soil organic carbon contents and soil carbon stock were higher under Bush managed (thinned) class compared to bush encroached. However, bush management (thinning) have not shown considerable effects on soil bulk density, pH, nitrogen contents and total nitrogen stock. Thus, understory vegetation and soil organic carbon were influenced by the presence of thinning, but soil bulk density, pH, nitrogen contents were not influenced by thinning in this study. Generally, bush management (thinning) increased the rangeland condition, however; the management is not sustainable in case the thinning practice is not followed recommended procedures because most of the encroacher species are sprout more densely within a short time.


Nowadays, the number of Thai elders is rapidly increasing among world elderly population, how to keep their health is a major concern. Cardiovascular Diseases (CVDs) which are severe diseases for Thai have higher mortality than cancers, and elderly people have a higher possibility to predispose CVDs. Hence, the risk factors for CVDs should be addressed. Obesity, as one of the risk factors of CVDs, seriously affects Thai elders' wellbeing; excessive sugar consumption is a way leading to overweight and obesity. The amount of consumed sugar by Thai is much higher than the standard sugar consumption, and it also could cause many other diseases. Therefore, this paper proposes a classification method for the elderly group who have the potential to control their blood sugar in order to prevent them from sugar overconsumption. This paper explored machine learning algorithms to find an appropriate classification method for elderly data. Artificial neuron network and K-nearest neighbors are applied for classifying elderly groups. Glycated hemoglobin (HbA1c) and fasting plasma glucose (FPG) are the noninvasive measurements of evaluating blood sugar, based on the two measurements, the 242 data from 121 elderly people are divided into two groups which are controllable group and uncontrollable group. The result indicates that the artificial neuron network is more suitable for the dataset with 70.59% accuracy as compared to the accuracy of K-nearest neighbors.

We propose an iterative method of determining the scattering indicatrix by values of the scattered radiation field intensity. In order to calculate a successive iteration we should solve a linear system of equations for components of a vector that defines a successive approximation to the sought function. The coefficients of this system are linear functional of the solution of a radiative transport equation and may be found by the Monte Carlo method. We briefly describe a method of calculating these coefficients. In conclusion we give the results of numerical experiments on the scattering indicatrix determination in a plane layer of a substance by the method proposed. The light scattering indicatrix is one of the most important parameters that define the process of radiative transport. It substantially depends on the composition of the medium, where radiative transport occurs (e.g. the composition and the form of aerosol particles). Making optical measurements of the scattered radiation field brightness, we can try to find the indicatrix and then draw a conclusion about the medium composition. The scattering indicatrix is a conditional probability density of the direction of a particle after a single event of scattering, given the direction immediately before scattering. Therefore the problem of determining the indicatrix is readily solved if a fraction of singly scattered radiation in the total flux strongly dominates over that of multiply scattered radiation. Otherwise things become much worse. A method of reconstructing the light scattering indicatrix in the atmosphere was proposed in [1]. This method is based on separating the indicatrix from the 'main part* of a radiation flux, i.e. singly scattered radiation. It allows one to satisfactorily solve the problem for the values of the optical atmospheric thickness r < 0.8. For large values of r we have to use different regularization methods based on the a priori information concerning the solution of the problem [3,5,8]. In this paper we propose another iterative method based on the transformation of the radiative transport equation that contains the scattering indicatrix as a parameter. 1.

The linear stability of freely propagating, adiabatic, planar premixed flames is investigated in the context of a simple chain-branching chemistry model consisting of a chain-branching reaction step and a completion reaction step. The role of chain-branching is governed by a crossover temperature. Hydrodynamic effects, induced by thermal expansion, are taken into account and the results compared and contrasted with those from a previous purely thermal-diffusive constant density linear stability study. It is shown that when thermal expansion is properly accounted for, a region of stable flames predicted by the constant density model disappears, and instead the flame is unstable to a long-wavelength cellular instability. For a pulsating mode, however, thermal expansion is shown to have only a weak effect on the critical fuel Lewis number required for instability. These effects of thermal expansion on the two-step chain-branching flame are shown to be qualitatively similar to those on the standard one-step reaction model. Indeed, as found by constant density studies, in the limit that the chain-branching crossover temperature tends to the adiabatic flame temperature, the two-step model can be described to leading order by the one-step model with a suitably defined effective activation energy.


The present investigation is focused to study the permeability of natural fiber during vacuum infusion (VI) process and the effect of the surface treatments of natural fiber, fiber loading direction, resin flow direction and process parameter on the tensile properties of developed composites (sisal/bio based epoxy). The bio based resin exhibits good flow characteristics in NaOH and isocyanate treated fibers which may be attributed to change in polarity. The surface treatments appear to provide an appreciable enhancement in tensile strength through enhanced bonding between fiber and matrix. The longitudinal tensile strength has been found to be higher than that of the transverse direction and the flow along the fiber provides maximum tensile strength. It has also been demonstrated that VI process provides improved mechanical properties as compared to hand-layup process. Morphological studies of fractured developed composites were performed by scanning electron microscopy (SEM) to understand the de-bonding of fiber/matrix adhesion. POLYM.

With the increasingly high demand for the quality of steel products, it is demanded that tundishes should have the functions of adjusting and controlling the temperature and composition of molten steel to further remove inclusions in steel. In industrial production, because of different products and production patterns, tundishes should be designed to have different shapes and casting strands, and tundishes can be used to produce continuous casting slabs or blooms with different sections. Asymmetric tundishs refer to the dualstand or multi-strand tundishs whose shape is asymmetric with the long nozzle as the axis or in which the flow of molten steel is in an asymmetric state because of the different flow of different strands. When asymmetric tundishes are used to cast, the molten steel flow characteristics from the long nozzle to different outlets vary, so the temperature of different outlets and the removing effect of inclusions in molten steel are different. As a result, the quality stability of continuous casting products cannot be ensured. Residence time distribution (RTD) is often used to analyze the fluid flow characteristics in a tundish. As for diverse RTD curves, many researchers have put forward correFluid Flow Characterization in Asymmetric Tundish

The Hellenistic poets did of course experiment with forms of praise poetry. Alan Cameron is prepared to admit the existence of paeans probably sung at royal festivals or victory celebrations. But as he says, 'Theocritus 17 is the only complete poetic encomion to survive from the Hellenistic world'. It is for that reason that this chapter briefly considers this particular poem, because it seems to demonstrate most clearly the actual nature of Hellenistic praise poetry. Theocritus refers to the existence of competitive performance at festivals, in his reference to the lavish prizes awarded by Ptolemy at the Alexandrian Dionysia; this feature of Ptolemaic culture is clearly an adaptation of the Athenian Dionysia. But Theocritus' poem can hardly be written for a festival of Dionysus: the chapter suggests that the obvious occasion explains all the distinctive features of the poem. Keywords: Alan Cameron; Alexandrian Dionysia; Hellenistic praise poetry; ptolemaic culture; Theocritus

Diuretic activities of three pteridines, including triamterene (SKF two of them, SK&F 371 and SK&F 8542 (triamterene), reduce the excretion of potassium at natruretic doses. It is suggested that trimterene acts directly upon a renal port system for sodium which is probably distal and includes the system involved in the exchange of sodium for potassium. While the site of action of triamterene may be in the same portion of the nephron as that affected by aldosterone, the pteridine has been reported to be capable of exerting its effects in the absence of adrenal steroids.

Acacia nilotica is a potential source of protein, fibre and natural antioxidants. Also, the protein fractions from acacia seeds possess high functional properties that could be advantageous in food formulation. However, acacia pods possess a bitterness that hinders its utilization for value addition. We have developed composite flours in combination with raw banana flour. Two types of composite flours were developed substituting 30 and 50 per cent of banana flour with acacia flour. Acacia flour exhibited significantly higher (p≤0.05) water and oil absorption capacity, swelling power as well as sedimentation value compared to banana flour. Also, it was a significantly richer (p≤0.05) source of protein (12.95%), crude fibre (12.66 %) as well as DPPH activity (59.60 %). The two composite flours, respectively exhibited 0.86 and 1.35 g/g water absorption capacity; 0.44 and 0.76 g/g oil absorption capacity; 4.14 and 4.06 g/g swelling power; 14.22 and 15.36 ml/g sedimentation value. The crude protein content in respective composite flours was 9.36 and 11.86 % with 4.96 and 5.50 % crude fibre, 40.60 and 40.69 % dietary fibre, 27.05 and 34.06 % DPPH activity. Both composite flours were good source of available micro-minerals also.


This paper presents a novel solar heat pump system operating using ice slurry as a latent storage material. The new system builds upon previous ice-based thermal storage systems through the addition of a new cooling mode using the ice tank as a cool storage reservoir. Cooling operations are split between distinct day and night modes, allowing for improved heat pump performance and potential peak load reductions. The proposed system is integrated with a detailed single family housing model in Montreal, Toronto, and Vancouver to investigate the potential of the system throughout Canada. Results demonstrate annual energy savings over 50% in all three regions.


The advance of iniatives called Solidary Economy in Brazil reveals the increase of a complex and contradictory social movement, that has been earning a new space in society. The recovered companies represent a whole new chapter on this scenery, given the particularities of its stories, internal organization and the social actors envolved. Such iniatives rise in times of economical crisis, as ways of attenuation of unemployment. This article aims to present a bibliographic review over recovered companies, highlighting the challenges that are part of the self-manager work. It will be developed after 3 moments: 1) charachterization of the new configuration of the work worldwide and in Brazil, and its repercussion on the rising of the solidary movement; 2) analisys of context data about the Solidary Economy development in Brazil; 3) reflexion over the self-manager experience in recovered companies, focusing on the contextual and organizational specificities of those enterprises.

The multiple processes which control motion at the bed of glaciers are too heterogeneous to be modeled directly, but a simple stick-slip slider-block model of a glacier bed allows a statistical mechanical treatment of the physics beneath thin and shallow sloped glaciers. The technique may reconcile apparently contradictory field observations of the relationship between glacier sliding and basal water pressure. Simulations also predict hysteresis in the relationship between water pressure and basal velocities.


In 'With a Plural Vengeance: Modernism as (Flaming) Brand', Michael Coyle examines the renaissance of modernism within the academic institution since the early 1990s, and the vigorous yet controversial re-branding through which this has in part been achieved. Defending this revisionary modernist studies, he argues that the issue for contemporary scholars is not primarily one of purging the elitism of a previously dominant 'high modernist canon', but of emphasising the pluralistic rather than singular criteria of canon-formation.


Objective: This study examines racial/ethnic differences in the prevalence, patterns, and correlates of cooccurring substance use and mental disorders (COD) among Whites, Blacks, Latinos, and Asians using data from the Collaborative Psychiatric Epidemiology Studies. Method: We first estimated the prevalence of various combinations of different co-occurring depressive and anxiety disorders among respondents with alcohol, drug, and any substance use (alcohol or drug) disorders in each racial/ethnic group. We then estimated the prevalence of different patterns of onset and different psychosocial correlates among individuals with COD of different racial/ethnic groups. We used weighted linear and logistic regression analysis controlling for key demographics to test the effect of race/ethnicity. Tests of differences between specific racial/ethnic subgroups were only conducted if the overall test of race was significant. Results: Rates of COD varied significantly by race/ethnicity. Approximately 8.2% of Whites, 5.4% of Blacks, 5.8% of Latinos, 2.1% of Asians met criteria for lifetime COD. Whites were more likely than persons in each of the other groups to have lifetime COD. Irrespective of race/ethnicity, the majority of those with COD reported that symptoms of mental disorders occurred before symptoms of substance use disorders. Only rates of unemployment and history of psychiatric hospitalization among individuals with COD were found to vary significantly by racial/ethnic group. Conclusions: Our findings underscore the need to further examine the factors underlying differences between minority and non-minority individuals with COD as well as how these differences might affect help seeking and utilization of substance abuse and mental health services.


INTRODUCTION Handwear testing with human subjects is conducted primarily because measured dry insulation values (1,.) from models may not reliably predict actual thermal protection experienced in the field. Total clothing insulation, sweating, individual activity level or thertuaI contact with external objects also affect hand temperatures. In this study, the physiological responses of eight volunteer subjects wearing the Combat Vehicle Crewman cold weather (CVC) and Light Duty (LD) gloves were tested in an environmental chamber. The CVC glove is an insulated one piece glove ofknit fire-retardant fabric with a leather reinforced palm. The LD glove is a two piece glove consisting of an uninsulated leather shell and a separate liner knit of wool and nylon. Glove total dry insulation (1,.) values were measured on two biophysical hand models (1). IT for the knit fabric CVC glove was measured as 0.16 m·K·W, (1.00 clo) and for the LD glove, IT was 0.12-0.14 m2·K·W" (0.80-0.92 clo).


Based on radar data and ground weather phenomenon, two kinds of severe convective weathers, hail and gale process and tornado process, are simulated by the model MM5. The simulated radar echo and actual radar echo are analyzed. Simulated micro-physics and dynamic characteristic are researched. The possible reasons of the difference with microphysical and dynamic characteristic between two kinds of severe convective weather are discussed. The results are as follows. ¿Simulated effect with two kinds of severe convective weather was good about the simulation of radar echo, so simulated radar echo had certain reliability. ¿That snow crystal was located above 0¿ level is showed by the microphysical simulation of hail process. The isoline of wave band, comparatively with rain-water was crowded. The cloud-rain mainly distributed below 0¿ level, and was scattered distribution. The rain distributed below and above 0¿ level. That cloud water continuously distributed below 0¿ level was showed by microphysical simulation of tornado process. The rainwater distributed below 0¿ level. The rainwater content distributed less below 0¿ level, but mainly distributed above 0¿ level, also the value was big, the isoline was crowded. The cloud ice content also presented scattered distribution. ¿The severe convective weather process corresponded to the strong lifting movement from the simulation of dynamic characteristic, but the region of strong lifting movement did not distribute specific position of the echo band.

cordingly, slowing of the maximum relaxation rate (MRR) of inspiratory muscles during short and sharp sniffs is considered to be an index of inspiratory muscle fatigue [5] . Sniff MRR is commonly calculated from esophageal pressure traces; however, a non-invasive and reliable measure of inspiratory muscle MRR can be obtained by measuring sniff nasal pressure [6] . This non-invasive technique has been validated in healthy normal subjects [6] and in patients with chronic obstructive pulmonary disease [7] . A remarkable contribution to defi ne the value of MRR by measuring sniff nasal pressure in patients with neuromuscular diseases has now been given by Garcìa-Rìo et al. [8] in this issue of Respiration . In this prospective controlled study including 20 patients with diagnoses of neuromuscular diseases and 10 healthy subjects, the authors examined the relationship between MRR (of both sniff nasal and esophageal pressures) and the tension-time index of the diaphragm. The authors found that patients with neuromuscular diseases had lower MRR values calculated from both esophageal and nasal pressure traces than control subjects. Furthermore, in these patients, the MRR assessed from sniff nasal pressure strongly predicted the corresponding MRR from esophageal pressure, and it was inversely related to the tension-time index of the diaphragm. Importantly, this study validates the sniff nasal MRR as Respiratory muscles, like limb muscles, experience fatigue, defi ned as a condition in which there is a loss in the muscle's capacity to exert force and/or velocity resulting from muscle activity under load, which is reversible by rest [1] . Respiratory muscle fatigue differs from respiratory muscle weakness, which is a condition in which the capacity of a muscle at rest to generate force is impaired [1] . Patients with neuromuscular diseases are predisposed to respiratory muscle fatigue. Reduced maximal pressure capabilities and increased load, secondary to decreased lung and chest wall compliance, can facilitate the onset of fatigue [2] . Furthermore, in patients with neuromuscular diseases, because of respiratory weakness, fatigue may occur at a much lower load than in healthy subjects [2] . Respiratory muscle fatigue may play a role in the development of exertion breathlessness and ventilatory failure in patients affected by certain neuromuscular diseases, e.g. amyotrophic lateral sclerosis, muscular dystrophies and myopathies [3] . In these patients, measuring respiratory fatigue may be of clinical relevance. During fatigue, muscles stiffen and sarcomere function may be expressed as both the velocity of shortening and relaxation of the muscle. Under fatiguing conditions, the relaxation rate of the diaphragm is slower than that of diaphragms without fatigue in normal subjects [4] . Ac-


ABSTRACT The synthesis of macrolide 2′-phosphotransferase I [Mph(A)], which inactivates erythromycin, is inducible by erythromycin. The expression of high-level resistance to erythromycin requires themph(A) and mrx genes, which encode Mph(A) and an unidentified protein, respectively. We have studied themphR(A) gene, which regulates the inducible expression ofmph(A). An analysis of the synthesis of Mph(A) in minicells and results of a complementation test indicated thatmphR(A) is located downstream from mrx and that its product, MphR(A), represses the production of Mph(A). DNA sequencing indicated that the mph(A), mrx, andmphR(A) genes exist as a cluster that begins withmph(A) and that the deduced amino acid sequence of MphR(A) can adopt an α-helix–turn–α-helix structure. To study the regulation of gene expression by MphR(A), we performed Northern blotting and primer extension. A transcript of 2.9 kb that corresponded to the transcript of mph(A) through mphR(A) was detected, and its level was elevated upon exposure of cells to erythromycin. Gel mobility shift assays and DNase I footprinting indicated that MphR(A) binds specifically to the promoter region ofmph(A), and the amount of DNA shifted as a results of the binding of MphR(A) decreased as the concentration of erythromycin was increased. These results indicate that transcription of themph(A)-mrx-mphR(A) operon is negatively regulated by the binding of a repressor protein, MphR(A), to the promoter of the mph(A) gene and is activated upon inhibition of binding of MphR(A) to the promoter in the presence of erythromycin.


Abstract The city of Sobral, state of Ceara, Brazil, introduced,in the year 2000, multi-professional teams in theFamily Health Program – PSF. These teams aimed topotentialize the actions of PSF and to guarantee theintegrality of care in promotion, prevention, assistan-ce and rehabilitation.

After the creation of theinstrument, the software was developed. The opera-tional system used was Linux, PHP language,POSTGRESQL database, and it is accommodated onan APACHE web server. The system was called SINAIat the beginning and provides important data for thedevelopment of indicators by various professionals,guaranteeing the production of epidemical informa-tion necessary for the process of control, evaluationand planning of team actions.Keywords: Information System; Epidemiology; FamilyHealth Program; Integrality.


The review provides a detailed account of the collective study of the oeuvre of the Russian-Argentinian legal scholar Evgeny Viktorovich Bulygin, the results of which are reflected in the book "How Is Logic in Law Possible?" (M. V. Antonov, E. N. Lisanyuk, E. N. Tonkov (eds.). St. Petersburg: Aleteia, 2021). It is emphasized that the research participants succeeded in carrying out a comprehensive analysis of the merits and deficiencies of Bulygin's logical positivism. Among the merits, most researchers consider the distinction between the rules of law and normative propositions, in virtue of which legal prescriptions came to lend themselves to logical analysis. The authors associate the weaknesses of logical positivism with its inability to justify normativity, as well as with the shortcomings of deductivism as a model of judicial argumentation.


This paper focuses on the recovery of bandlimited signals from level-crossing samples by exploiting not only the knowledge of when given levels are crossed by the input, but also the implicit information that the signal stays between neighboring levels in the time intervals between the level crossings. We propose to use the technique of projection onto convex sets (POCS) for perfect signal reconstruction from either the level crossings or the associated implicit information. Two POCS algorithms are proposed: iterative POCS and one-step POCS. While the one-step POCS is based on matrix inversion, the iterative projections can be implemented using a chain of standard circuit operations: a low-pass filter and a clipping circuit, respectively. The perfect signal recovery of the infinite projection iteration can be viewed as the completion of the nonperfect input reconstruction achieved in continuous-time digital signal processing from level crossings. The comparative analysis of simulation results for both iterative and one-step POCS algorithms show the importance of a good selection of the initial guess for the POCS reconstruction.


A method is proposed to manipulate the annihilation dynamics of a dense gas of positronium atoms employing superradiance and subradiance regimes of the cooperative spontaneous emission of the system. The annihilation dynamics is controlled by the gas density and by the intensity of the driving strong resonant laser field. In particular, the method allows to increase the annihilation lifetime of an ensemble of positronium atoms more than hundred times by trapping the atoms in the excited state via collective radiative effects in the resonant laser and cavity fields.


For Ax well of NB 35-2 oilfield,Minghuazhen unconsolidated sand reservoir is very heterogeneous with sand grains sorted poorly and sand produced easily,the whole sand-control zone is longer with large space between sand-control intervals,and the hole is highly deviated.In order to overcome those difficulties,the temporary plugging workover liquid has been developed and three matching technical measures(controlling the tip screen-out,sand-out pressure appearing ahead of time and pumping sand slurry) have been adopted to perform fracture-packing sand control to five layers in Ax well successfully,which has provided experiences for same fracture-packing sand control operation in highly deviated wells in Bohai Sea.


The C(0001) face of silicon carbide (SiC) has superior properties such as a faster oxidation ratio and a smoother surface compared with the Si(0001) face. We have investigated the oxidation and post-oxidation annealing effects on the capacitance–voltage and the interface state density (Dit) of n-type SiC metal–oxide–semiconductor (MOS) structures formed on the C(0001) face. It was found that pyrogenic oxidation and hydrogen annealing above 700 °C reduced Dit near the conduction-band edge. The value of Dit at Ec−E=0.2 eV is 1×1012 eV−1 cm−2, which is comparable with that of the MOS structure formed on the Si(0001) face. However, the value of Dit around the deep level at Ec−E=0.6 eV is one order of magnitude higher than that of n-type MOS structures formed on the Si(0001) face. It is very important to reduce Dit at the deep level for a high-quality SiO2/SiC interface on the 4H-SiC C(0001) face.

The in-plane compressive behaviour of thin-skin stiffened composite panels with a stress concentrator in the form of an open hole or low velocity impact damage is examined analytically. A fracture mechanics model, developed initially to predict notched compressive strength, was applied to estimate the compression-after-impact strength of a stiffened panel; in the analysis the impact damage is replaced with an equivalent open hole. The influence of the stiffener on the compressive strength of the thin-skin panel is examined and included in the analysis. A good agreement between experimental measurements and predicted values for the critical failure load is obtained.


Faculty members at some medical schools report that they face harassment and intimidation from their students, colleagues and administrators. "We need to look at intimidation of faculty by residents," Dr. William Wrixon, associate dean of postgraduate medical education at Dalhousie told physicians


In this paper, probabilistic interpretation of the Kober fr actional integration of non-integer order is proposed. We p rove that the fractional integral, which is proposed by Kober, can be i nt rpreted as an expected value of a random variable up to a co nstant factor. In this interpretation, the random variable descri bes dilation (scaling), which has the gamma distribution. T he Erdelyi-Kober fractional integration also has a probabilistic interpret ation. Fractional differential operators of Kober and Erde lyi-Kober type have analogous probabilistic interpretation. The proposed int erpretation leads to a possibility of generalization of the fractional integration and differentiation by using continuous probability distr ibutions.


By encoding diplomatic correspondence (as a measure of state behaviour) according to the references to the prevailing law and global international system, we can demonstrate the conformity between state behavior and principles of international law states claim to guide their actions. Over time we can assess the impact of these norms on state behavior.

Taken together, these elements allow for an interpretation of European international relations during 1713-1739 as well as a comparison with other (historical) periods. In a multipolar environment, states are bound to integrate law in their legitimating discourses, in order to convince the other players of the well-foundedness of their own views.


ABSTRACT Introduction: The objective was to evaluate the perceived risks, barriers and stages of change on smoking cessation among the Malay male security guards. Materials and Methods: In the year 2004, a cross sectional survey was conducted on a group of security guards working in the campus and the hospital of a public university in Kuala Lumpur. Universal sampling (n=210) was conducted with a response rate of 88.6%. A self-administered questionnaire was used to survey the participants on their smoking status, stages of change, perceived risks and barriers to smoking cessation. Results: There were 37% current smokers and 23.7% ex-smokers. The mean year of smoking was 19.2 + 8.1 and the number of cigarettes smoked was 16.4 + 8.0 per day among the current smokers. About two-third of the smokers perceived the amount smoked currently was bad for health. However, only 23.3% and 30.9% of the smokers perceived themselves to be at higher risk for lung cancer and heart disease respectively. The three main reasons to quit smoking were health reasons, doctors' advice and cost. The main barriers were addiction (53.3%) and stress (28.3%). Most of the smokers (42%) were in the pre-contemplation stage with half of them not having thoughts of quitting. Conclusion: The smokers had misperception on smoking and majority was at the pre-contemplation stage of change in smoking cessation. The findings of this survey add on to the existing literature about the perception of risks, barriers and stages of change to smoking cessation. This will provide valuable information on the planning and delivering of smoking cessation programmes in the local context. KEYWORDS: Barriers, Stages of change, Smoking cessation


two weeks by culture (as above) was negative. We recently published another case within our region where diagnosis was delayed by several years following a TV-positive cervical cytology report. This patient had also experienced multiple negative HVS results, with the addition of negative assessments in GU medicine, before the diagnosis was made. This lady had developed chronic vulval ulceration and underwent vulval surgery as a result; her husband required a circumcision for phimosis secondary to chronic balanoposthitis. We raised this with members of our northern British Association for Sexual Health and HIV (BASHH) group and we contacted cytology laboratories in the northeast to assess their wording of the reporting for TV. This varied from stating 'Trichomonas-like organisms seen' to the report described in this case. Current cytology guidance states asymptomatic detection of this protozoon merits treatment in all cases, all patients should be referred to a local GU medicine clinic. Specialist transport medium for TV culture is often not available in primary care and so charcoal swabs are in widespread use. This practice further reduces the sensitivity of wet mount microscopy, which under optimal conditions stands at 70%. Newer nucleic acid amplification tests, which have significantly higher sensitivity, are currently being evaluated in our region but are not yet in routine use and are not available to all GU medicine service providers. Within our region the positivity rate of TV is in the order of 0.3–0.5% of women being tested at GU medicine services (local annual report data). We would encourage GU medicine consultants to contact their local cytology laboratories to discuss the wording of the reports for TV. We are also raising this issue centrally with the national cervical screening programme. We would suggest the report should read 'Trichomonas-like organisms seen; please discuss with your local GU medicine service' and we are in the process of arranging this with our local cytology service. Examination, wet mount microscopy and TV culture should then be performed as a minimum requirement for all TV-positive cervical smears. We would suggest that the woman should be given the choice of treatment regardless of results due to the low sensitivity of current confirmatory tests and be informed of the possibility of false-positive smear reports for TV (specificity of smears for TV diagnosis is 97%). Where the woman is unable to access or declines to attend a level 3 GU medicine service then treatment of her and any current partners should be given regardless of the HVS result. This pragmatic approach would help to prevent the long-term morbidity associated with TV (including genital symptoms, male infertility and effect on pregnancy) and potential increase in HIV transmission. In the future, should newer more sensitive tests for TV become widely available to primary care this approach could then be revised.


Radiobiological model such as linear quadratic is widely used in clinical radiotherapy to predict the biophysical response of the tumour cell to the radiation. This study investigates the radiation cell survival using Linear Quadratic and Multi-Target model and their radiobiological parameters. The experimental works were conducted in-vitro using HeLa cells that were irradiated using photon and electron beams of different energy. Cells irradiation were performed in full scatter condition and exposed to radiation doses ranges from 1 to 10 Gy. Clonogenic assay is used as an endpoint to obtain the cell survival curves which later be fitted with linear quadratic and multi-target model. The results demonstrate that Multi-target model produce the fitting curves that are closed to the experimental data compare to linear quadratic model especially at high doses. Parameter analysis from both models indicates more biological damage inflicted by high energy electron beam. Correlation between the experimental cell survival data and radiobiological model analysis suggesting that radiobiological model could be applied in analysing cells' radiation survival and damage

PurposeThe purpose of this study is to analyze the relationship between international portfolio investments and the country governance quality. MethodologyIn this study, based on panel data analysis of 18 emerging market countries from 2002 to 2018, the impact of governance quality on international portfolio investments was examined. These emerging countries are Argentina, Brazil, Chile, Colombia, Greece, Hungary, Egypt, Indonesia, India, Malaysia, Mexico, Peru, Poland, Philippines, Russia, South Africa, Thailand and Turkey. The main proxies for a country's governance quality are the World Governance Indicators (WGI). FindingsAs a result of the analysis, it was observed that the quality of governance indicators, excluding political stability and absence of violence, had a positive effect on international portfolio investments. Voice and accountability were observed to be the variable that most affected portfolio investments. Voice and accountability were followed by government effectiveness. Control of corruption, rule of law and regulatory quality were other indicators of governance that affected portfolio investments respectively. In this study, foreign direct investments, current account deficit, stock market size and stock market returns were used as control variables. As a result of the analysis, it was concluded that there is a negative relationship between foreign direct investments, current account deficit and international portfolio investments. There is also a positive relationship between stock market size, stock market returns and international portfolio investments. ConclusionThe empirical results tend to confirm the positive influence of governance quality on international portfolio investments.

Word sense disambiguation improves many Natural Language Processing (NLP) applications such as Information Retrieval, Information Extraction, Machine Translation, or Lexical Simplification. Roughly speaking, the aim is to choose for each word in a text its best sense. One of the most popular method estimates local semantic similarity relatedness between two word senses and then extends it to all words from text. The most direct method computes a rough score for every pair of word senses and chooses the lexical chain that has the best score (we can imagine the exponential complexity that returns this comprehensive approach). In this paper, we propose to use a combinatorial optimization metaheuristic for choosing the nearest neighbors obtained by distributional selection around the word to disambiguate. The test and the evaluation of our method concern a corpus written in French by means of the semantic network BabelNet. The obtained accuracy rate is 78 % on all names and verbs chosen for the evaluation.


Glyoxal-linked 2'-deoxyuridine 5'- O -mono- and triphosphates were synthesized through CuAAC click reaction of 4-azidophenylglyoxal or the Sonogashira reactions of 4-bromophenylglyoxal with 5-ethynyl-dUMP or -dUTP. The triphosphates were used as substrates for enzymatic synthesis of modified DNA probes using KOD XL DNA polymerase. The glyoxal-linked nucleotides reacted with arginine-containing peptides to form stable imizadolone-linked conjugates. This reactive glyoxal modification in DNA was used for efficient bioconjugations and cross-linking with Arg-containing peptides or proteins (e.g. histones) and was found to be more reactive than previously reported 1,3-diketone-linked DNA probes.


In 1888, Brazil, with a mostly black and mixed race or mulatto population, was the last country in the Western Hemisphere to abolish slavery. During more than 300 years of slavery in the Americas, it was the largest importer of African slaves, bringing in seven times as many African slaves to the country, compared to the United States.


The synthesis of the first gallepin derivative, the neutral gallium-based analogue of the tropylium ion, is described. The title compound, containing two gallepin moieties linked by a TMEDA unit, was characterized by 1H NMR, elemental analyses, and single-crystal X-ray diffraction. In addition, computations provide insight into the nature of the bonding and aromaticity of this novel compound.


The students' motivation in learning English is very important, due to English language mastery. Besides, the teacher needs an effective learning method, to encourage the students' motivation in the learning process. This research aims to analyze the use of Discovery-based Learning to encourage students' activeness in the classroom. This research was an experiment. The instrument used in this study were observation sheet and motivation questionnaire. The results of this research showed that the use of discovery-based learning in the classroom is very effective to engage the learners' motivation to participate actively in the classroom. The mean score of motivation is achieved in posttest (4.17) compared to pretest (3.81).  From the result of t test, the value of Sig. (2-tailed) is .041 which is lower than .05. The application of discovery-based learning is focused on student-centered activity, so that the learners can be more active in the learning process. In other words, the application of discovery-based learning is very appropriate to encourage the students' motivation to participate actively in the classroom.


E XPANDING intracranial masses can cause neuronal dysfunction by several possible mechanisms. A rapidly expanding mass lesion may produce vascular compression and ischemia of brain tissue adjacent to the lesion. Brain substance remote from the mass also can be rendered ischemic because of the particular vulnerability of its blood supply to distortion and compression2 A notable example is compression of the posterior cerebral artery against the edge of the tentorium. A third mechanism to be considered is alteration of the electrical and chemical properties of neurons by distortion of their architectural arrangement. This is particularly pertinent in evaluating the significance of brainstem displacement and distortion. The purposes of the present investigation were to study displacement and distortion of the brain and intracranial vascular compression produced by acute expansion of an extracerebral balloon, and to correlate these effects with pressure measurements from various intracranial compartments. Particular attention was directed to gross morphological changes in the brain stem.


Abstract The article presents information on how to use satellite interferometry to detect linear discontinuous ground deformation [LDGD] caused by underground mining. Assumptions were made based on the properties of the SAR signal correlation coefficient (coherence). Places of LDGD have been identified based on these assumptions. Changes taking place on the surface between two acquisitions lead to worse correlation between two radar images. This results in lower values of the SAR signal correlation coefficient in the coherence maps. Therefore, it was assumed that the formation of LDGD could reduce the coherence value compared to the previous state. The second assumption was an increase in the standard deviation of coherence, which is a classic measurement of variability. Therefore any changes in the surface should lead to increasing standard deviation of coherence compared to the previous state. Images from the Sentinel-1 satellite and provided by the ESA were used for analysis. The research is presented on the basis of two research areas located in the Upper Silesian Coal Basin in the south of Poland. The area in which LDGD could occur was limited to 6 % of the total area in case 1 and 36 % in case 2 by applying an appropriate methodology of satellite image coherence analysis. This paper is an introduction to the development of a method of detecting LDGDs caused by underground mining and to study these issues further.


venous system, and it certainly is a very entertaining and well-written essay, full of detailed knowledge and wide philosophy. After dealing with the structure, anatomy, comparative anatomy, and embryology of the veins, the author reviews our knowledge of absorption by veins, and of the relation of the nervous system to the veins. It seems clear, from a perusal of this survey, that the innervation of the veins and the relation of this to the various functions of the body are much more important than is generally believed. Another large section of the book is devoted, as might be expected, to the part played by the veins in connexion with the venous return to the heart, and here the author introduces an account of his own investigations carried out with the aid of x-ray cinematography with opaque injections. The pressure and movement of blood in the veins are fully treated, though these chapters contain less that is new to the average reader. Finally we have an excellent chapter on clinical aspects of the veins-for example, varicose veins, thrombosis, phlebitis, air emboli -and a chapter on the use of the various photographic techniques in research on veins. This chapter could with advantage have been made longer, because Dr. Franklin has unique experience in this field of investigation. It is evident that the production of this work has been largely a labour of love on the part of its author, who has every reason to feel satisfied that he has done the work as fully and as well as it could have been done. He has probably a better acquaintance with the ancient literature on the subject than any other person has ever had; we learn from this monograph that his knowledge of recent work is equally comprehensive. The bibliography should not be forgotten-it covers fifty-three closely printed pages, andshows the same close attention to minute detail as does the rest of the book. The printing and illustrating are unexceptionable.


Abstract A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable pacing was not obtained until the catheter tip stimulated the left atrium. Four months after discharge from the hospital the patient was doing well, and left atrial pacing has continued.


Combining data-sharing models and algorithm technologies has led to new data flow structures and usage patterns. In this context, the presentation time of shared low-sensitivity information across platforms has become a crucial factor that affects user perception and privacy-regulation behavior. However, previous studies have not conducted an in-depth exploration of this issue. Based on privacy process theory, this study discusses the impact and potential mechanism of the presentation time (immediate or delayed) of shared low-sensitivity information across platforms on privacy-regulation behavior. Through a pre-study and two online survey experimental studies, which included 379 participants in total, we verified that the immediate information presentation time has a significantly higher impact on online vigilance and privacy-regulation behavior than the delayed condition, βdirect = 0.5960, 95% CI 0.2402 to 0.9518; βindirect = 0.1765, 95% CI 0.0326 to 0.3397, and users' perceived control as the moderating role influences online vigilance and privacy-regulation behaviors (preventive or corrective), βpreventive = −0.0562, 95% CI −0.1435 to −0.0063; βcorrective = −0.0581, 95% CI −0.1402 to −0.0065. Based on these results, we suggest that the presentation time of using shared low-sensitivity information across platforms should be concerned by companies' recommendation algorithms to reduce users' negative perceptions and privacy behaviors and improve user experience.


The relation between different levels of public concern about the environment and sociodemographic and behavioral variables are main issues in several recent investigations. Many of these are based on the idea that environmental interest is shaped by personal beliefs. However, the internal structure of those beliefs is not well understood. In this investigation, 3 studies (N = 96; N = 397; N = 400) explored what different types of beliefs concerning people/environment relationships exist and how they are internally organized. Multidimensional techniques such as INDSCAL and facet theory were used to analyze the similarity structure of items asking for beliefs toward the environment. Three viewpoints were identified: ecocentric, anthropocentric, and beliefs based on an interest in material progress. Most participants reported an ecocentric belief. Results concerning the structural analyses are compatible with a strong relation between the anthropocentric and material progress approaches and with the assumption of independence of all 3 beliefs.


Attenuation coefficients for atmospheric absorption were calculated from hourly meteorological data observed at Nagoya Observatory in central Japan during a year. The calculated results show that the attenuation coefficients at law and high frequencies are higher in winter than those in summer, although the attenuation coefficients at middle frequencies become high in summer, and that the attenuation coefficients at all frequencies in daytime tends to be higher than those at night. Moreover it has been clarified quantitatively that the attenuation coefficients in a sunny day are higher than those in a rainy day. As a result of this study, it has been found that the attenuation coefficients for atmospheric absorption vary strongly due to the changes of real atmospheric conditions during a year in Japan. 1 INTRODUCTION Attenuation coefficients for Atmospheric absorption depend strongly on air temperature and humidity. There are large variations with time and place in meteorological conditions. These natural variabilities are often neglected in environmental impact assessments. It is necessary to examine the fluctuation of the attenuation coefficients for atmospheric absorption in order to predict outdoor sound propagation more accurately. 2 CALCULATION METHOD Attenuation coefficients for atmospheric absorption were calculated from hourly meteorological data observed at Nagoya Observatory in central Japan from 1 April 1991 to 31 March 1992 by using the calculation method described in the ISO 9613-1. The meteorological data used in the calculations were temperature, humidity and atmospheric pressure at a height of 1.5m above the ground. Nagoya Observatory is in a suburb of Nagoya city and stands on high ground at a height of 51.1m above the sea level. Fig. 1 shows a scatter diagram of relative humidity versus air temperature observed hourly in the year. Temperature vary within the range from −2.9oC to 36.8C, relative humidity vary with in the range from 17% to almost 100% in the year. The change of the seasons is quite noticeable in Japan, the air is relatively warm and moist in the summer, and cold and dry in the winter. 3 CALCULATED RESULTS 3.1 Temporal fluctuation in the year Fig. 2 shows the attenuation coefficients for atmospheric absorption at octave band center frequencies form 63 Hz to 8kHz, together with the air temperature and the relative humidity used in the calculation. It can be seen that the attenuation coefficients at law (63,125Hz) and high (4k,8kHz) frequencies in the Copyright SFA InterNoise 2000 2 Figure 1: Scatter diagram of relative humidity versus temperature observed hourly at Nagoya in central Japan for the year (April 1991 to March 1992). winter are higher than those in the summer. On the other hand, the attenuation coefficients at middle frequencies (500,1kHz) become lower in the winter. The temporal fluctuation of attenuation coefficients at all frequencies become greater in the winter than in the summer. The mean, standard deviation, maximum and minimum of the coefficients (n=24*365=8760) are shown in Fig. 3 and Table 1. The attenuation coefficients vary strongly in the year. For example, attenuation coefficients at 2kHz vary within the range from 7.8 dB/km to 34.0dB/km, while the mean annual attenuation coefficient is 11.5dB/km. Temp. [C] R.H.

The attenuation coefficients at high and law frequencies in the winter are high than those in the summer. On the other hand, the attenuation coefficients at middle frequencies are low in the winter. It can be said that the seasonal changes in the attenuation coefficients depend strongly on the frequency. It is difficult to answer the question whether A-weighted sound pressure level in summer Copyright SFA InterNoise 2000 3 Figure 2: Air temperature, humidity and calculated attenuation coefficients due to atmospheric absorption at octave band center frequencies form 63Hz to 8kHz in the year. at a distant point form a sound source increase or not, without the information of the spectrum of the sound source.

Table 3 and Fig. 5 show mean absorption coefficients of 109 sunny days and those of 87 rainy days in the year. In this study, all days in the year were divided into three weather types (sunny, cloudy and rainy) according to the weather symbols written in the reports of surface daily observation. There is a tendency that the attenuation coefficients are high in the sunny days than in the rainy day. It should be noted that the tendency is clearly seen in the attenuation coefficients at law and high frequencies, although the attenuation coefficients at middle frequencies are not changed drastically by weather conditions.

The results are shown in Table 4. There is a tendency that the attenuation coefficients at night become lower than those during daytime.

Much attention is paid in the recent years to the mobility properties of the components of cell surface membranes, especially specific receptors and antigens, since the description of the dynamic behavior of these macromolecules is necessary for the understanding of the mechanism of signal transduction through the biological membranes. The use of time-resolved optical methods for studying the rotational and lateral diffusional movements of membrane proteins was a subject for a number of reviews. This work provides a brief account of the use of time-resolved phosphorescence anisotropy decay measurements for studying the rotational dynamics of the integral membrane proteins on the surface of living cells.


The productivities of cowpea are low, depending on the use of low productivity capacity cultivar planted, associated with the use of low-quality seeds. The objective of this work was to evaluate the agronomic characteristics and physiological quality in seed lots of different cultivar of cowpea in the "Cerrado", Goias State, Brazil. The experimental design was a complete block with four replicates. The treatments were eight cultivar of cowpea (BRS Guariba, BRS 17 Gurgueia, BRS Rouxinol, BRS Marataoa, Patativa, BRS Tracuateua, BRS Milenio e CE 315), recommended for the North and Northeast regions of Brazil. The effects of the treatments were considerable for all the characteristics assessed. The cultivar BRS Guariba, BRS 17 Gurgueia and BRS Marataoa, presented less intense powdery mildew symptoms. The cultivar presenting higher yield were BRS Guariba and BRS Gurgueia, with 2,211 and 2,196 kg ha -1 of gr ain, respectively. The results showed that physiological seed quality influenced productivity of the cultivar. The cultivar BRS CE 315, BRS Gurgueia, BRS Rouxinol, BRS Marataoa and Patativa, with colored hull, produced seeds of better physiological quality compared, to the cultivar of white hull BRS Tracuateua, BRS Milenio and BRS Guariba.


In light of the potential use of single-molecule magnets (SMMs) in emerging quantum information science initiatives, we report first-principles calculations of the magnetic exchange interactions in [$\mathrm{Mn}_{3}$]$_{2}$ dimers of $\mathrm{Mn}_3$ SMMs, connected by covalently-attached organic linkers, that have been synthesized and studied experimentally by magnetochemistry and EPR spectroscopy. Energy evaluations calibrated to experimental results give the sign and order of magnitude of the exchange coupling constant ($J_{12}$) between the two $\mathrm{Mn}_{3}$ units that match with fits of magnetic susceptibility data and EPR spectra. Downfolding into the $\mathrm{Mn}$ $d$-orbital basis, Wannier function analysis has shown that magnetic interactions can be channeled by ligand groups that are bonded by van der Waals interaction and/or by the linkers via covalent bonding of specific systems, and effective tight-binding Hamiltonians are obtained. We call this long-range coupling that involves a group of atoms a collective exchange. Orbital projected spin density of states and alternative Wannier transformations support this observation. To assess the sensitivity of $J_{12}$ to external pressure, stress-strain curves have been investigated for both hydrostatic and uniaxial pressure, which have revealed a switch of $J_{12}$ from ferromagnetic to antiferromagnetic with increasing pressure.


The study determined the involvement of youths in cattle rearing at the rural community level using six randomly selected communities in Oyo State in the South western part of Nigeria. Twenty – five youths were randomly selected from each of these communities and interviewed. The study found that 68% of the respondents who were involved in cattle rearing were males, 32% were females, while seventy three percent (73%) were between 21 and 30 years. The most significant finding of this study is that 16% of these youths possessed tertiary (that is, post secondary) education. These Nigerian youths perceived cattle rearing as labour - intensive, non - mechanized and unattractive. Chi - square analysis showed that there was no significant association between respondents' age and cattle rearing (χ2 = 5.935, P > 0.05) while there was significant association between respondents' educational status and cattle rearing (χ2 = 35.042, P < 0.050).

Recent Chilean theatre, insisting on processing collective trauma, has developed procedures that bend canonic dramaturgies through staging in peculiar spaces and embodiments charged with symbolic weight, thus articulating the renewed critical horizon of post-dictatorship generations. This procedure is explored through the deconstruction of the theatrical, performative, and dramatic threads of Guillermo Calderón's staging in 2010 of Aguirre's text Los que van quedando en el camino. First staged in 1969 by DETUCH, the play was looked upon as the "right" performance, congruent with the utopic prerevolutionary times of its emergency. This study proposes that Calderón composes his production as an allegory of the personal/historical rub between the always declining and nonetheless persisting personalhistorical urge towards memory, a process he claims is condemned to a catastrophic failure.


The demands for improved performance of lithium ion batteries (LIBs) have been increased for hybrid electric vehicle and electronic devices. In order to obtain enhanced LIBs capacity, high capacity anode materials such as Si, Ge, Sn and SnO2 have been attractively studied and considered as promising anode materials to alternate commercial graphite, which exhibited 372 mAhg of theoretical capacity. [1-4] However, the large volume expansion up to 300% and pulverization during Li-ion insertion/extraction are occurred and mechanical failure and loss of electrical contact at the electrode are followed. To overcome the above problems, various strategies have been suggested. Among those strategies, size-down to nanoscale is one of most promising solution. The yield and fracture strengths of materials increase dramatically by the grain size of nanoscale therefore the nano-sized anode materials can sustain severe stress and strain without fracture and destruction during alloying process with Li-ion. The design of porous structure is another solution to prepare enough free space for the accommodation of volume expansion. In this study, we developed the robust and facile strategy to synthesize the nano-sized SnO2-TiO2 core-shell nanotube using PAN template. SnO2 and TiO2 were coated in order by atomic layer deposition with nanoscaled thickness and post annealing was conducted for removing PAN template and crystallization. SnO2 is one of the promising materials for anode electrode of LIB due to its high theoretical capacity (782 mA h g). [3] However, as mentioned problem, practical implementation of SnO2 to the anode for LIBs is greatly hindered by large volume expansion. To obtain solution on this problem, SnO2-TiO2 core-shell nanotubes suggest two kinds of structural design for the anode of LIBs. SnO2 was synthesized with the shape of nanotube of 10nm thickness having free space inside to accommodate volume expansion and TiO2 was coated the outer surface of SnO2 nanotube. TiO2 showed relatively low capacity but its structural stability during alloying/dealloying with Li-ion and rapid Li-ion insertion/extraction were widely well-known. [5] Therefore, TiO2 shell can play a role for the capsulation of SnO2 against its volume expansion. From the morphologies and phase analysis, we confirmed the shape of nanotube and thickness of SnO2 and TiO2 layer and each thickness of SnO2 and TiO2 were precisely controlled. Using this SnO2-TiO2 core-shell nanotube, coin cell was fabricated and its cycling performance was evaluated.

Recent developments in multiple-frequency and multiple-angle tomography for the scanning tomographic acoustic microscope (STAM) are presented. The STAM extends the capabilities of the scanning laser acoustic microscope by using tomographic processing to recover the depth information. Recently, high-quality tomographic reconstructions were obtained by addressing the problems of projection phase errors and projection misalignment. In addition to discussing these implementation problems for the STAM, the authors present reconstructions using experimental data for both multiple-frequency and multiple-angle tomography. These results demonstrate the feasibility and reconstruction improvement of the STAM.<<ETX>>


An important puzzle in …nancial economics is why fund managers invest in short-maturity assets when they could obtain larger pro…ts in assets with longer maturity. This work provides an explanation to this fact based on labor contracts signed between institutional investors and fund managers. Using a career concern setup, we examine how the optimal contract design, in the presence of both explicit and implicit incentives, a¤ects the fund manager's decisions on investment horizons. A numerical analysis characterizes situations in which young (old) managers prefer short-maturity (long-maturity) positions. However, when including multitask analysis, we …nd that career concerned managers are bolder and also prefer assets with long maturity. Key words.

Abstract The induced voltage on the telecommunication cable generated by nearby electric railway system may bring about telecommunication errors and safety accidents. In order to reduce the induced voltage and to achieve communication reliability, the effect of the shield cables and the recent double-track railway systems on the inductive interference should be investigated. This paper analyzes the parameters which seriously influence the induced voltage on the telecommunication cables which run parallel with a AT-fed electric railway line, and provides a simulation-based approach to estimate the amount of the induced voltage. Simulation results indicate that the induced noise voltage generated by a double-track railway decreases by 18 % compared to that generated by a single-track railway, showing the screening effect by nearby track. The induced noise voltages on the 50%-shielded cable and 15%-shielded cable decrease to 1/8 and 1/15 of the induced voltage on the non-shielded cable, respectively. A meaningful shield effect is achieved and the induced voltage is minimized by the double-track railway and the shielded cable.


In this paper,due to the effect of positively-charged screening holes,the Coulomb potential energy 1/r is modified to be 1/rp.Using many-body quantum perturbation theory,we obtain a simple analytic representation of the ground state energy for a two-dimensional electron gas.It is found that the ground-state energy E and equilibrium radius reps are dependent on the interaction parameter p.Our results agree with those obtained by the numerical simulations and semi-analytic methods at low density limit.


Why co-production? There is a very good technical and environmental argument for choosing this technology. In a traditional steam based powerplant with condensing operation, only 40-45 percent of the energy input is converted into electrical power. The remaining part is lost with the cooling water into the sea and with the hot flue gas up through the stack. In a CHP plant the electrical power is generated in the same way as in a power plant, but instead of disposing of the cooling water, the steam is cooled by the return water in a district heating system and thus used for generation of heat. As the society needs both heat and power, combined heat and power generation is environmentally and economically advantageuos. The exploitation of the fuel input is much better, which is the main reason that the development within the CHP sector has a high priority in the Danish energy policy. The structural possibilities for utilising the heat produced by CHP plants are good in Denmark as a large part of the heat supply is covered by district heating. This means that the CHP plants and thus the electricity production in Denmark is to a large extent decentralised as opposed to a structure with large central power plants with a demand for seawater cooling.

0. Introduction . It has been proved by K. Yano [7J that in a compact orientable Riemannian manifold an infinitesimal affine transformation is an infinitesimal motion. But it seems that the assumptions of "compactness" and "orientability" are too strong or unnecessary. In this respect, K. Nomizu [5] has recently given very suggestive lemmas on the relations between the group A(M) of all affine transformations and the group I(M) of all isometries in a Riemannian manifold M. According to one of his lemmas, in an irreducible Riemannian manifold the affine transformation may be considered as the homothetic one. Furthermore so far as the identity component Ao(M) of A(M) is concerned, we may restrict our consideration to the irreducible or locally flat parts of the Riemannian manifold M. Thereby we shall first treat of the properties of the homothetic transformation and show that in some complete Riemannian manifold a homothetic transformation is necessarily an isometry. We shall next apply this to affine transformations in an irreducible Riemannian manifold. Afterwards we shall consider the locally flat case. In the last section we shall give some examples which show that the assumptions in our theorems can not be made weak.

The purpose of this study was to enhance the performance of the Adaptive-model (AM) for Chlorophyll-a (Chl-a) concentration estimation using MODIS-imagery. The AM is based on the combination of spectral response classification and three semi-empirical estimators. Most critical step in Chl-a estimation when using the AM is the estimator selection. A wrong selection could lead to an over- or underestimation and induces a staircase effect in Chl-a modelization. Ensemble based systems (EBS) development can be in interesting solution. One of the most used techniques to develop an EBS is bagging-algorithm. However, its main weakness is time consumption. The Gaussian-quadrature (GQ) formula has the potential to handle this kind of problems. The objective of this study is to develop a mixed ensemble based system for Chl-a estimation in Quebec inland waters using GQ formula. Statistical indexes evaluation was satisfied, relative-RMSE=15% and R2=0.98 whereas matrix-confusion results were 0.92 and 0.8 for global-success and Kappa-index, respectively.

Background information. Acid‐secreting gastric parietal cells are polarized epithelial cells that harbour highly abundant and specialized, H+, K+ ATPase‐containing, tubulovesicular membranes in the apical cytoplasm. The Golgi apparatus has been implicated in the biogenesis of the tubulovesicular membranes; however, an unanswered question is how a typical Golgi organization could regulate normal membrane transport within the membrane‐dense cytoplasm of parietal cells.


Purification of carbon nanotubes (CNTs) is a very actively discussed topic in contemporary CNT literature. To a large extent, impurities embedded in CNTs influence the physical and chemical characteristics of the CNTs. Different purification methods yield different CNT characteristics and may be suitable for the production of different types of CNTs. Developments in the purification methods of CNTs are reviewed, and the production methods are briefly discussed and summarized. This is followed by a detailed description of the three major purification methods, viz. chemical, physical, and multi-step purification.


This paper intends  to explore the various ways in which social media can be used to enhance learning and engagement, as well as the potential challenges and risks that may arise. The study focuses on face-to-face formal K-12 education which is a system that generally covers 12 grades including primary and secondary schools. The manuscript provides a comprehensive theoretical literature review of the existing research on the topic, highlighting the main findings and discussing the implications. Social media platforms such as Facebook, YouTube, and Twitter have turned into an increasingly prevalent and influential aspect of modern society, and they have also begun to infiltrate the realm of education. However, during this study it has been noticed that there are few studies examining the effects of social media in K-12 education. Namely, some research has been conducted on higher or online education. Accordingly, while there are certainly benefits to applying social media in education, such as the ability to connect with a global network of learners and access to a vast array of information and resources, there are also challenges that must be considered. Thus, the results of this study provide clarification on previous research and lay the foundation for future examinations of the potential advantages and disadvantages of using social media in K-12 education.


The film of Farewell to my Concubine by Kaige Chen presents three types of verbalization on the point of the political and cultural fate:First,although art cannot divorce from politics and history for independent survival,it cannot be controlled by both and never become the tool of that.Second,Peking Opera together with all of the national art lost the stable rear and were under the aphasia situation of "be watched" in the time of modern China that was not only suffered from the internal political turmoil but also the external colonial aggression.Third,if it wants to have a long-term development,the Peking Opera must be changed from the shackles of conventional thinking,keep pace with the times and do innovation with the help of new communication forms and advanced technology.

(Abridged)One of the fundamental challenges for astrophysics in the 21st century is finding a way to untangle the physical processes that govern galaxy formation and evolution. Given the importance and scope of this problem, the multi-wavelength astronomical community has used the past decade to build up a wealth of information over specific extragalactic deep fields to address key questions in galaxy formation and evolution. These fields generally cover at least 10square degrees to facilitate the investigation of the rarest, typically most massive, galaxies and AGN. Furthermore, such areal coverage allows the environments to be fully accounted for, thereby linking the single halo to the two-halo terms in the halo occupation distribution. Surveys at radio wavelengths have begun to lag behind those at other wavelengths, especially in this medium-deep survey tier. However, the survey speed offered by the JVLA means that we can now reach a point where we can begin to obtain commensurate data at radio wavelengths to those which already exists from the X-ray through to the far-infrared over ~10 square degrees.
We therefore present the case for a 10 square degree survey to 1.5uJy at L-band in A or B Array, requiring ~4000 hours to provide census of star-formation and AGN-accretion activity in the Universe. For example, the observations will allow galaxies forming stars at 10Msolar/yr to be detected out to z~1 and luminous infrared galaxies (1000Msolar/yr to be found out to z~6. Furthermore, the survey area ensures that we will have enough cosmic volume to find these rare sources at all epochs. The bandwidth will allow us to determine the polarisation properties galaxies in the high-redshift Universe as a function of stellar mass, morphology and redshift.


The localized molecular orbitals (LMOs) of thiophene, furan, and pyrrole are derived from ab initio 4‐31G wavefunctions using Boys' criteria for localization. From the transferability point of view, these LMOs are classified as (i) completely different and nontransferable LMOs (these are the lone‐pair orbitals on O and N on one hand and those on S on the other hand), (ii) chemically similar lone pairs and inner shells on O and N (of furan and pyrrole, respectively), and (iii) chemically equivalent CC, CC, and CH LMOs in the three heterocycles. The sp3 hybridization of the L core of sulfur, its appreciable polarization, and considerable involvement in bonding in the CS bond region have been discussed. The present investigation indicates the limitation of the application of semiempirical MO methods to molecules that contain second‐row atoms due to both the appreciable core—valence and π‐σ interactions involving such atoms. Qualitative investigation of aromaticity and reactivity of the studied heterocycles agrees satisfactorily with experimental observations and shows that conclusions drawn based solely on static factor considerations (charge distribution in the noninteracting molecules) might very well be misleading and such factors determine the ease rather than the final orientation of the substituent.


169 Perform, Repeat, Record collects a wealth of insights, artifacts, and exchanges germane to pressing issues at the nexus of performance and historiography. Scholars will find it essential to navigating emerging currents of thought at the dynamic intersection of visual arts and performance studies, and it will serve as a useful supplement for courses on performance art. Its likely impact on the field is more difficult to assess, in part because of the multiple and loosely affiliated aims that it serves. At once a collection of otherwise dispersed essays on the structures that stitch performance into time, a sampling of diverse historiographical and curatorial procedures, and a survey of the edges and seams that compose the evolving archive of live art, it seems to have absorbed from many of the artists discussed in its pages a tendency to defy definition.


A lattice vector quantization encoding method is developed based on ℓ1-norm-based enumeration and bit-plane coding. The algorithm is implemented for the cubic lattice, can handle arbitrary vector dimension, and is suitable for transform, subband, or wavelet coding applications. Moreover, the algorithm can possibly extend to other binary lattices.


We show experimentally that wavefront - the direction, spectral composition and phase profile of light emission - stimulated by free electron injection into plasmonic and dielectric media can be controlled with high finesse using holographic nanostructures.


A wiretap model with two receivers equipped with fixed-size cache memories, and a type II adversary is considered. The adversary in this model chooses a subset of symbols to tap into either from cache placement, delivery transmission, or both phases. The legitimate parties do not know the fractions or the positions of the tapped symbols in either phase. For a library of size three files or more, lower and upper bounds on the strong secrecy capacity, i.e., the maximum achievable file rate while keeping the overall library strongly secure, are derived. The strong secrecy capacity is identified for the instance of large tapped subsets. Achievability is established by wiretap coding, security embedding codes, one-time pad keys, and coded caching techniques. The upper bound is constructed by three successive channel transformations.


SUMMARY A striking feature of the tomographic images of the Earth's mid-mantle is the long, high-velocity belt extending in a north‐south direction under the North and South American continents, which is believed to be the remnant subduction of the Farallon Plate. In the Oligocene epoch the North Farallon Plate subduction terminated off Baja California and the South Farallon Plate broke into the Cocos and Nazca plates. This important period of the Farallon subduction history is not clearly understood, due in part to the lack of high-resolution tomographic images. Our P-wave tomographic image of the mantle below Mexico indicates that the currently subducting slab of the Cocos Plate is torn apart from the already subducted slab of the ancient Farallon Plate in a region behind the slab window or slab gap off Baja California. We suggest that the southeastward advance of this slab tearing was synchronous with the counter-clockwise rotation of the Cocos Plate against the eastward to northeastward subduction of the ancient Farallon Plate. The Cocos slab torn apart from the deeper Farallon slab dips to the north to northeast with its strike oblique to the trench axis. This slab configuration delineates well with the intermediate-depth earthquake activity and the volcanic activity known as the Trans Mexican Volcanic Belt. Further to the south of the slab tearing of the subducted slab continues from the deeper Farallon part to the shallower Cocos part but with considerable distortion in the shallower part.


Acinetobacter baumannii has been worldwide recognized as a pathogen causing serious infections in humans, leading to great concern about its presence in hospital environments (Kamble, 2015). Hospitalized patients who have undergone invasive procedures or even in immunosuppressive conditions can easily be affected by this microorganism (Patwardhan et al., 2008). Although not very common, ocular infections, particularly endophthalmitis, caused by the Acinetobacter genus species (including the A. baumannii), have been frequently observed in the literature in recent years (Talreja et al., 2014a). The aim of this report is to describe a case of eyeball evisceration associated with A.
