The Australian Learning and Teaching Council (ALTC) Discipline Scholars for Law, Professors Sally Kift and Mark Israel, articulated six Threshold Learning Outcomes (TLOs) for the Bachelor of Laws degree as part of the ALTC's 2010 project on Learning and Teaching Academic Standards. One of these TLOs promotes the learning, teaching and assessment of self-management skills in Australian law schools. This paper explores the concept of self-management and how it can be relevantly applied in the first year of legal education. Recent literature from the United States (US) and Australia provides insights into the types of issues facing law students, as well as potential antidotes to these problems. Based on these findings, I argue that designing a pedagogical framework for the first year law curriculum that promotes students' connection with their intrinsic interests, values, motivations and purposes will facilitate student success in terms of their personal well-being, ethical dispositions and academic engagement.


Adolescent employment research has focused on middle-class rather than disadvantaged adolescents. We identified risks and benefits of adolescent employment in a 12-month study of 715 low-socioeconomic-status female African American adolescents using nearest-neighbor Mahalanobis matching on baseline factors including substance use and socioeconomic status. Employed adolescents were more likely to graduate high school and less likely to depend on boyfriends for spending money, but they were more likely to use marijuana, alcohol, and have sex while high or drunk. Employment may help female adolescents avoid potentially coercive romantic relationships, but increase access to drugs or alcohol.

Along the way, he has managed to examine the meaning of South African history and recent changes from the perspective of some of its participants. Their dilemmas, the tug between westernization and a reconstructed tradition, are clearly present. The characters come alive. Madumo is not the everyman we anthropologists too often construct. Neither is he a "Noble Savage." Rather, he is a real person complete with fl aws. Similarly, various religious practitioners, fellow townspeople, family, and others have their own virtues, weaknesses, and peculiarities. There is, alas, the now required soul-searching of the western character, who hates to leave the fi eld—but, of course, does. But even here, Ashforth manages to avoid most of the clichés and brings his refl ections to life. All in all, this book is a fi ne example of blurred genres and the way in which such an account can illuminate important cultural issues. I recommend the book highly as an enjoyable and enlightening experience. Frank A. Salamone Iona College


Two fast least-squares lattice algorithms for adaptive nonlinear filters equipped with bilinear system models are presented. The lattice filter formulation transforms the nonlinear filtering problem into an equivalent multichannel linear filtering problem, thus using multichannel lattice filtering algorithms to solve the nonlinear filtering problem. The computational complexity of the algorithms is an order of magnitude smaller than that of previously available methods. The first of the two approaches is an equation error algorithm that uses the measured desired response signal directly to compute the adaptive filter outputs. This method is conceptually very simple, but results in biased system models in the presence of measurement noise. The second is an approximate least-squares output error solution; the past samples of the output of the adaptive system itself are used to produce the filter output at the current time. Results indicate that the output error algorithm is less sensitive to output measurement noise than the equation error method. >


In this article, bisphenol A epoxy resin (E-51) as A group, Methyl tetrahydrodiphosphonic anhydride (MTHPA) as A curing agent, and acid anhydride crosslinking system epoxy resin samples were prepared. By establishing a condensation discharge platform, the surface condensation of epoxy resin was studied by temperature, relative humidity, and filth degree. The influence of hygrothermal corona aging on the surface flashover voltage of epoxy resin in the condensation state was analyzed by static contact Angle, scanning electron microscope, and infrared spectrum. The results showed that with the increase of temperature difference, relative humidity, and fouling degree, the surface condensation quality of epoxy resin also increased, and the temperature difference had the greatest effect on the surface condensation quality. With the increase of aging time, the static contact Angle decreased from 83.8° to 36.7°. At the same time, a large number of cracks appeared on the surface of the material, accompanied by skin shedding, and the surface decomposition and carbonization phenomenon occurred. The decomposition of the -COOR group and -C=O group inside epoxy resin is accompanied by the generation of -OH and -COOH groups. The surface flashover characteristics of epoxy resin are positively correlated with the content of water molecules in the air, and the hydrophilic -OH and -COOH groups lead to the degradation of its electrical properties. The research results of this article can provide a reference for the operation and maintenance of switchgear with epoxy resin as the main insulation structure.


In this study we examined the physiological responses of different strains of gilthead sea bream (Sparus aurata) to chronic and acute stress factors. Blood glucose levels, hematocrit, and lactate concentrations were examined in yearlings of different strains of gilthead sea bream subjected to different stress situations. In the first experiment, fish of the Ardag and 'ebony' strains were kept 45 days in moderate (35-45 kg/m 3 ) or high (70-90 kg/m 3 ) density. There were no significant effects on the blood glucose level but, at both densities, hematocrit was significantly higher in the Ardag strain (33.2±3.0% at moderate and 44.5±1.6% at high) than in the ebony strain (22.0±3.0% and 19.9±2.7%, respectively). The interaction of 'strain' and 'crowding' was highly significant, suggesting that hematocrit may respond differently in each strain to crowding. In the second experiment, we examined the effects of acute stress (handling without anesthesia) among four strains representing Mendelian mutations that affect body coloration in gilthead sea bream: ebony, 'white', 'yellow', and the normally pigmented Ardag. Significant variations in the glucose and lactate concentrations suggest that genotypes of gilthead sea bream may have heritable differences in their physiological responses to stress factors.


little or no attempt to explore their meaning or possible interconnection. Drinking among Teen-agers, by contrast, generates a wealth of exciting possibilities for further investigation. For instance, the symbolic potential of alcohol use for group identification and for the legitimation of unconventional behavior are also briefly but penetratingly explored. And, to mention another, the reader soon finds himself wondering about alternative mechanisms for the transformation

A QUANTITATvE assessment of the adequacy and efficiency of workmen s compensation in the United States amounts to a Herculean task, if not a Sisyphean labor. The investigator pursuing such a goal soon finds himself ensnarled in a web of perplexities, the escape from which leads inextricably into a quagmire of guesswork. The main pitfalls and obstacles stem from three converging sets of factors: (1) the wide disparities and inherent complexities of the coverage provisions and benefit formulae of the 54 governing systems;' (2) the increasing overlaps between more recent systems of social insurance (especially federal survivors and disability insurance) and workmen's compensation; and (3) the appalling lack of pertinent data and statistics. Nevertheless, it would seem to be possible to arrive at some significant conclusions of a semi-quantitative character by a composite evaluation of various available data and extrapolation of ascertainable trends and developments. Two principal lines of approach appear to be helpful in this endeavor: On the one hand, one might try to construct a model of an ideal system of workmen's compensation and inquire to what extent any of the existing arrangements falls short of the optimal expectations. On the other hand, one might take any of the existing arrangements and inquire to what extent its performance has been improved in the course of time. A combined util-


Today, composite materials are involved in more and more high-performance applications, particularly in vital parts for the aeronautical industry. This is the reason why the prediction of the evolution of damage up to fracture is a crucial topic in the design of composite structures. An important challenge for the aeronautical industry today is to substitute long and expensive experimental investigations with numerical simulations, called "virtual testing". But a determining factor in making that change is one's level of confidence in models, which must be very high.

Analytical mechanics provides methods for analyzing multibody systems with mathematically equivalent elastic elements. The paper analyzes several of these models, highlighting the advantages and disadvantages offered by each of these methods. The main methods used by the researchers are described in a unitary form, presenting the methods of obtaining the evolution equations in each of these cases, mentioning the strengths and weaknesses of each method. The equations of Lagrange, Gibbs–Appell, Kane, Maggi, and Hamilton are analyzed for the particular case of two-dimensional systems, which present certain particularities that facilitate the analysis.


China Edna O'Brien (1930- ), an Irish novelist, poet, and short story writer, is considered as a pioneer for her frank portrayals of women and the most gifted woman writing in English at her time. Her first novel, The Country Girls (1960), was an immediate success. Her writing is lyrical and intense with passions and aspirations. Set in Britain, the short story Cord describes a story about how the mother and the daughter got along in the short reunion after a long separation. The paper mainly explores different religious values, cultural values, and social values between them which caused irreconcilable conflicts. The present paper concludes that the "Cord", the blood tie, can never get rid of the spiritual barrier. Only mutual understanding can eliminate the gap and acquire a harmonious relation between parents and


This paper presents an approximation method of statistical distribution of the largest eigenvalue of i.i.d. (independent and identically distributed) MIMO (multiple input multiple output) channel correlation matrices under Nakagami-Rice fading environment. The equation is actually derived for MIMO Nakagami m fading channel which is known as a good approximation of Nakagami-Rice fading, hence it well approximates the curves of the largest eigenvalue distribution of noncentral Wishart matrices. In the proposed approximation method, MIMO MRC (maximal ratio combining) system is ascribed to SIMO space diversity theory with the same number of branches, and the statistical distribution becomes a monomial gamma distribution. As a result, the derived marginal density function does not contain any special functions, and has a simple monomial gamma form which is suitable for various calculations of performance indices. Through computer simulations, it is shown that the proposed approximation formula is effective and has a better precision than conventional method.


Dmisteinbergite (dmist) is a metastable hexag-onal form of CaAl_2Si_2O_8, with space group of P6_3/mcm, a = 5.10A and c = 14.72A [1]. First occurrence of meteoritic dmist has been reported in the Allende Type B2 FUN CAI STP-1 [2], where it appears to have crystallized from a ^(16)O-rich (Δ^(17)O ~ −25‰) silicate melt via rapid cooling [3]. Here we report on an-other textural occurrence of dmist in STP-1 - ^(16)O-poor (Δ^(17)O ~ −2‰) fine-grained crystals in alteration zone of the inclusion.


Ultraviolet absorption spectrum, infrared absorption spectrum and flotation solution chemistry were studied of scheelite and benzoylhydroxamic acid. The results have shown that benzoylhydroxamic acid has the optimum flotation pH values ranging from 7 to 10. At the range of pH 3.7~13 7 Ca 2+ acts as a locating ion for scheelite, and O,O chelation takes place between benzoylhydroxamic acid and Ca 2+ on the surface of sheelite to form five membered ring chelate. At the same time Co absorption between ion and molecule occurs, chieving the optimum flotation effect.


Horizontal and temporal variations in abundance and productivity of phytoand zooplankton were studied in a frontal area in the NW North Sea during September and October 1985. In addition, distributions of several cohorts of herring larvae found in this area were monitored and larval growth and survival estimated. Phytoplankton biomass and productivity as well as copepod productivity peaked in the transitional zone between isothermal and temperature-stratified water. Copepod egg production was observed to increase markedly subsequent to a severe storm. The frontal region, then. was identified as particularly productive in terms of larval herring food (immature copepods), and frequent autumn storms may also stimulate the production of larval food. Six larval cohorts were identified within the study area, all with estimated instantaneous mortalities of <0.05 d-'. Upon hatching in AugusWSeptember, larvae patches dnfted towards the south until the end of the study in late October. Throughout thls period, larvae tended to be retained within the frontal region. Crossfrontal transects revealed peak abundances of larvae in transitional water concurrent with peak copepod production. In spite of this, larval growth was suboptimal and limited by food availability. It is shown that larval feeding was of the same order of magnitude as production of larval food and it is suggested that competition for food in the larval stage contributes to density-dependent growth, survival and, hence, recruitment.

Two greatly understudied areas of science are the number of species on Earth (May 1994) and the rate at which they are becoming extinct (Myers 1994; Lawton & May 1995). These are formidable questions, with few regions having good let alone repeated surveys of fauna and flora. The biodiversity of Britain is among the best recorded, however, and Red Data Books (RDBs), which can be used to estimate British extinction rates, are available on several invertebrate taxa (Shirt 1987; Bratton 1991). A compilation of species listed in the RDB (Shirt 1987) as probably extinct before 1900 suggests that 1% of the British insect fauna became extinct "this century" (May et al. 1995). We use the same source to estimate the extinction rate, but we use probable extinctions since 1900.


This fine book comes at an opportune time. Three decades after the first UN conference on women, female representation is widely accepted around the globe as both a human right and a democratic norm. In the last 15 years, women have entered national legislatures in unprecedented numbers. Representing Women in Parliament offers a nuanced account of how and why this happened, with what substantive impact, in four Westminster parliaments—the United Kingdom, Canada, Australia, and New Zealand. It also looks at new routes of political access opened up by institutional innovation: in Britain, the devolution of power to Scotland, Wales, and Northern Ireland; in Canada, the creation of Nunavut Territory for the Inuit people. A comparison limited to Westminster regimes might seem too restricted to illuminate broader patterns of representation, but in fact these cases encompass large differences in party and electoral systems, trajectories of women's mobilization, and institutional opportunity structures. There is also significant variation in levels of female representation, ranging from a high of 50 percent Wales to a low of 10.5 percent in Nunavut. In the editors' words, ''It is the combination of commonalities and variations that makes the comparison so useful—comparing apples and crab-apples, perhaps, rather than apples and pears'' (2).

When working or exercising for prolonged periods in hot and humid environmental conditions, high sweat rates can lead to dehydration and electrolyte imbalance. It is well established that these progressive conditions will impair work and exercise performance in both athletes and manual workers. Consequences of inadequate fluid and electrolyte replacement in both cases can range from uncomfortable heat cramps, to more serious cases of heat illness, which in extreme cases can be fatal. Fluid loss accompanying work or exercise in the heat has received extensive focus in the literature over the last 20 years, however, the sodium losses associated with large sweat losses have received far less attention. Due to the well-established link between high salt intake and hypertension, the World Health Organisation recommends that on a global scale individuals consume less than 5g salt per day. While these recommendations may be appropriate for the general population, the athlete or manual worker has substantially greater sodium losses and therefore is hypothesised to require a higher sodium intake. One of the principle aims of this thesis is to document sweat sodium losses and provide appropriate guidelines for fluid and sodium replacement in both manual workers and endurance athletes. Chronic hyponatremia is a condition previously reported to occur in military personnel where over several weeks sodium intake is inadequate to replace large sweat losses. To date no previous study has investigated the incidence of chronic hyponatremia in a group of manual workers. Maintaining adequate fluid and electrolyte balance is essential to this population who are often working for prolonged periods in hot and humid environments. To investigate the incidence of chronic hyponatremia in this population, plasma sodium levels were assessed at the end of both the summer and winter months. Despite the similar dietary sodium intake across the year, the incidence of chronic hyponatremia at the end of the summer period was significantly greater than at the end of the winter period. This was postulated to be due to the higher sweat losses as a result of the more harsh environmental conditions during the summer months. Dietary sodium intake was found to be inadequate to replace the estimated sodium losses due to the high proportion of rice and legumes consumed with very low sodium content. Increasing the sodium content of fluid and food provided to workers is warranted and may reduce the incidence of work related illness and accidents in this population. In the athlete population there has been a great deal of focus in the literature on the need to adequately replace fluid losses that occur as a result of heavy sweating. Far less attention has been on the need to replace the sweat sodium losses accompanying this, with few studies documenting sodium losses in an endurance athlete population. There is large inter-individual variation in both sweat rate and sweat sodium loss in athletes with both factors being influenced by exercise intensity and duration, environmental conditions, physical fitness, size and number of individual sweat glands as well as the acclimatisation state of an athlete. It is therefore difficult to establish general recommendations for sodium intake in this population. In some athletes sodium losses can be replaced by normal dietary intake, whereas in other cases increased dietary intake is essential to replace large sweat sodium losses. In order to accurately determine sweat electrolyte losses, comprehensive laboratory based assessment is required, however this is often not practical. Chapter 4 and 5 of this thesis determined the effect of exercise intensity, seasonal heat acclimatisation and physical training status on fluid and electrolyte losses in a group of endurance athletes. The results from both of these studies predicts that endurance athletes with high sweat rates are at risk of both sodium and potassium deficiency, which may impair performance, if dietary intake is not sufficient to replace losses. Simple measures such as pre and post exercise weighing may be a useful tool in determining individual fluid and sodium intake requirements when comprehensive laboratory assessment is not practical. Based on the findings from these three studies, fluid and electrolyte replacement recommendations have been made for both manual workers and athletes working and exercising in thermally stressful environments.


Dimension stone is a highly valuable raw mineral material per unit of product. From the past experiences and literature it is known that for a certain quantity of commercial blocks, dimension stone a significantly larger volume of natural (raw) rock mass, should be dug (cut) out. Stone residue, resulting in gaining the commercial dimension stone blocks, is usually less value per unit of product. Profitability of the dimension stone exploitation in a deposit is directly dependent on the rock coefficient of utilization. It is therefore a priority task and a challenge to improve the efficiency of dimension stone deposits utilization and reduce the accumulation of mineral residue that would ultimately increase profits. Dependence of profitability on coefficient of utilization of dimension stone deposits can be best expressed by numerical models, as shown in this paper.


Modified method of segmentation of objects on the raster image of foundry defects on the basis of the active contour algorithm is developed. The method is developed in a base set of functions of interactive segmentation of a programming complex "The System of foundry defects discerning on raster image". The entrance information is the photo of foundry defect. The output information is a raster segment containing the image of foundry defect.


Oil and gas exploitation in regions of ultra-deep water has already been started and there is a great expectation of growth in the coming years, mainly in the region known as Pre-Salt, at Brazilian's coast. Operators, which have the concession to exploit this region, have adopted different solutions with different configurations using rigid and flexible pipes for this initial phase. However, the last structural type mentioned shows to be much more versatile, providing attractive cost/benefit solutions to the operators, in which, only in Brazil, it is forecasted a demand about 4.000 km of flexible pipes in the next years [1]. With new challenges coming, one may ask the following question: What is the structural reliability of each failure mode of these flexible pipes? Motivated by this question, this paper has the objective to do a preliminary analysis, under the structural reliability view, of the critical failure mode for the design of flexible pipes faced in Brazil, represented by the fatigue phenomenon on metallic layers. The work assesses the fatigue reliability of the armour wires, located in the bend stiffener region, for two 6″ flexible risers configurations, free-hanging and lazy-wave. They are considered to be installed in ultra-deep water (2140m depth) and are submitted to the same external environmental loads. The fatigue reliability methodology used is based on that presented in Ref. [2] including new random variables. Sensitivity analyses are also performed for the variables that most contributes to the quantified probability of failure. Calibrated safety factors (SF) are obtained for different target failure probabilities.Copyright © 2015 by ASME


A restoration plan recovering sandy beaches at Tennozaki in Lake Kasumigaura was investigated. Past lakeshore changes were first investigated through the comparison of old map and aerial photographs. A stable shoreline of a pocket beach was predicted by applying a modified Hsu model (Serizawa et al., 1996). Numerical simulation using a contour-line-change model considering the change in grain size proposed by Kumada et al. (2003) was also carried out. Three-dimensional beach changes when beach nourishment was carried out were predicted by this model.


A high-speed crusher comprises a crushing cavity, a crushing assembly, a crushing sorting piece and a motor, wherein the crushing assembly comprises a rotating shaft, a plurality of cutter frames, and a plurality of movable cutters; the rotating shaft penetrates through the centers of the cutter frames, and one end of the rotating shaft is in transmission connection with the motor by a belt wheel; the crushing cavity comprises a first cavity bracket, a second cavity bracket and static cutters; and the static cutters are respectively fixed on the first cavity bracket and the second cavity bracket. In the high-speed crusher, the cutter frames and the rotating shaft of the crushing assembly adopt a whole structure, so that the high-degree dynamic balance can be realized in the rotating process, the vibration can be effectively reduced, and the service life of the crusher can be prolonged. A blade of each cutter adopts a V shape, so that the contact areas between materials and the blades are reduced, and the wearing of the blades can be reduced.


The accuracy of the use of spectral analysis as a method of quantitative interpretation of Doppler-shift flow signals from chronically implanted probes was investigated in sheep and ponies. Doppler-shift flow probes, chronically implanted around the pulmonary artery, were used to obtain a continuous beat-by-beat measurement of cardiac output. The average velocity blood flow in the vessel was found by spectral analysis, and output calculated using the internal diameter of the vessel. The results were compared with those obtained simultaneously by the dye dilution method. In these circumstances the Doppler-shift flow probes gave results which accurately reflected changes in cardiac output, and which were quantitatively at least as accurate as those measured by dye-dilution methods.


OBJECTIVES
To investigate the value of quantitative dynamic contrast-enhanced MRI (QDCE-MRI) and diffusion-weighted MRI (DW-MRI) in differentiating nasopharyngeal carcinoma (NPC) from lymphoma.

METHODS
We retrospectively analysed the data from 102 patients (82 with NPC and 20 with lymphoma) who underwent pre-treatment QDCE-MRI and DW-MRI on a 1.5-T MR unit. QDEC-MRI parameters [influx transfer constant (K(trans)), efflux rate constant (Kep), fractional volume of extravascular extracellular space (Ve) and fractional volume of plasma (fPV)] based on pharmacokinetic model and apparent diffusion coefficient (ADC) were compared between the two nasopharyngeal malignancies.

RESULTS
The K(trans), Kep, Ve, fPV and ADC values (mean ± standard deviation) for NPC were 0.366 ± 0.155 min(-1), 1.353 ± 0.468 min(-1), 0.292 ± 0.117, 0.027 ± 0.024 and 0.981 ± 0.184 × 10(-3) mm(2) s(-1), respectively. The K(trans), Kep, Ve, fPV and ADC values (mean ± standard deviation) for lymphoma were 0.212 ± 0.059 min(-1), 1.073 ± 0.238 min(-1), 0.213 ± 0.104, 0.008 ± 0.007 and 0.760 ± 0.182 × 10(-3) mm(2) s(-1), respectively. Optimal cut-off values (area under the curve, sensitivity, specificity) for distinguishing the two tumours were as follows: K(trans) = 0.262 min(-1) (0.866, 80.49%, 85.00%), Kep = 1.401 min(-1) (0.681, 43.90%, 100.00%), Ve = 0.211 (0.784, 76.83%, 85.00%), fPV = 0.012 (0.779, 60.98%, 85.00%), ADC = 0.761 × 10(-3) mm(2) s(-1) (0.781, 93.90%, 55.00%).

CONCLUSIONS
QDCE-MRI together with DW-MRI is useful for differentiation between NPC and lymphoma.

Polymer covered cylindrical rolls are typically used in different paper machine sections like in calenders and in coating units. The main reason for the use of soft-coated rolls is that by using the soft rolls the contact area becomes larger. Strongly loaded line contact causes deformations and heat generation in the polymer cover. In paper production process impurities, like paper pieces, may catch on the surface of the roll. Impurities cause locally larger deformation in the cover. The local deformation produces a higher local temperature area, which can cause cracks in the cover, to loosen the cover from the base and to fracture the cover locally. If a local failure happens the fragments of the cover can damage also the other rolls. In this paper an operation monitoring system for on-line monitoring of roll cover is presented. The system is installed in a laboratory pilot roll installation, where the rolling contact consists of a hard and a soft roll. The measurement system consists of on-line measurement of acoustic emission (AE) of the roll. Additionally the temperature distribution of the roll, the ploymer cover and the position angle of the roll are measured. The measurement signal is transferred from the rotating roll via wireless local area network (WLAN) to the measurement computer. The measurement control computer is connected to the LAN of the laboratory and the measurements can be followed and analyzed with different computers and also via Internet. The paper describes the principles of acoustic emission signal processing and analysis and the construction of the wireless Ethernet-based operation monitoring system.© 2002 ASME

Nowadays, telepresence systems based on the Extended Reality (XR) system are actively developed and used for remote collaboration due to COVID-19. Still, several issues, such as limited traversable space in Virtual Reality (VR) and require all participants to wear head-mounted display (HMD), stop these systems from being used in our daily life. On the other hand, telepresence robots have been used in various fields before the pandemic. However, these robots also have a limitation in that the current form is incapable of delivering non-verbal expressions, which is essential for social interaction. Therefore, we present a Holobot, a telepresence robot based on the XR system. A remote user connects to the Holobot through VR HMDs, and the Holobot augments a virtual avatar that projects users' facial and gesture expressions. We developed a prototype and conducted a simple field test in the exhibition to receive feedback. VR participants enjoyed exploring remote spaces and interacting with each other through Holobot. Furthermore, remote space participants mentioned that a 1:1 scale avatar helped to build co-presence with the VR user. Based on these insights, we think Holobot could provide design guideline for future telepresence robot. For further approach, we plan to improve our prototype and conduct user test for structured evaluation of our system.


This paper presents a novel circuit topology of a high efficiency single-phase sinewave PV power conditioner. This power conditioner is composed of time-sharing sinewave absolute pulse width modulated boost chopper with a bypass diode in the first power processing stage and time-sharing sinewave pulse width modulated full-bridge inverter in the second power processing stage operated by time-sharing dual mode pulse pattern control scheme. Its unique operating principle of two power processing stage with time-sharing dual mode sinewave modulation scheme is described with a design example. This paper also proposes a sinewave tracking voltage controlled soft switching PWM boost chopper with a passive auxiliary edge-resonant snubber. The new conceptual operating principle of this novel single-phase sinewave power conditioner related to solar photovoltaic generation system is presented and discussed through the experimental results.


Reperfusion therapy must be applied as soon as possible to attenuate the ischemic insult of acute myocardial infarction(AMI).However reperfusion is responsible for additional myocardial damage,which likely involves opening of the mitochondrial permeability transition pore(mPTP).In reperfusion injury,mitochondrial damage is a determining factor in causing loss of cardiomyocyte function and viability.Major mechanisms of mitochondrial dysfunction include the long lasting opening of mPTPs and the oxidative stress resulting from formation of reactive oxygen species(ROS).Several signaling cardioprotective pathways are activated by stimuli such as preconditioning and postconditioning,obtained with brief intermittent ischemia or with pharmacological agents.These pathways converge on a common target,the mitochondria,to preserve their function after ischemia/reperfusion.The present review discusses the role of mitochondria in cardioprotection,especially the involvement of adenosine triphosphate-dependent potassium channels,ROS signaling,and the mPTP.Ischemic postconditioning has emerged as a new way to target the mitochondria,and to drastically reduce lethal reperfusion injury.Several clinical studies using ischemic postconditioning during angioplasty now support its protective effects,and an interesting alternative is pharmacological postconditioning.In fact ischemic postconditioning and the mPTP desensitizer,cyclosporine A,have been shown to induce comparable protection in AMI patients.

The dual-purpose welding wire accommodating frame is convenient to use. The space is utilized fully and effectively, the production speed can be increased, and the cost is reduced.


Activation of store operated Ca2+ (SOC) entry promotes inter‐endothelial cell gap formation. Mammalian transient receptor potential proteins 1 and 4 (TRPC‐1, 4) are subunits of SOC entry channels and contribute to an endothelial cell Ca2+‐selective SOC entry channel (ISOC). Based on homology with voltage‐gated K+ channels it is currently believed that TRPC proteins form channels by coalescence of four subunits. The idea of a tetrameric structure was supported in a study by Schaefer et al using heterologously expressed TRPC6 in a FRET based approach. While heterologously expressed TRPC6 forms a homotetramer, it is presently unclear whether endogenous TRPC proteins also form tetramers. We therefore sought to determine the oligomeric state of the endogenous ISOC channel. Our approach was to cross‐link lysine residues residing in the extracellular loops of TRPC1 and TRPC4. Rat pulmonary artery endothelial cells (PAEC) were treated with cross‐linking agents of spacer arm‐lengths 7.7 Å, 11.4 Å and 16.1 Å. Cells were then lysed and homogenized, and proteins analyzed via SDS‐PAGE. Immunoblotting for TRPC4 revealed a band representative of a tetramer configuration in samples cross‐linked by the 7.7 Å spacer arm. Thus TRPC4 contributes to an endogenous tetrameric channel configuration in PAECs.


Photodegradation of MCPA in aqueous solutions has been studied using UN. radiation and simulated sunlight with sensitizers. The main photoproducts have been characterized and a possible sequence of hotodecomposition
leas been postulated. The kinetic study has been carried
out in both processes for initial reaction times. It has been proved that the riboflavine, contained in husk rice is one of the most effective sensitizers to degrade MCPA.


Introduction: Glottic insufficiency which is inability to obtain complete vocal fold approximation during phonation is a common cause for dysphonia. Vocal fold immobility, vocal fold sulcus, presbylaryngis, vocal fold scarring are common causes. Materials and methods: We have studied 30 cases of glottic insufficiency that failed conservative management and underwent surgical intervention. Voice parameters like maximal phonation time (MPT) and voice handicap index (VHI) have been used as assessment parameters along with laryngoscopic examination. Observations and results: Twenty-one cases had vocal fold immobility, while the rest had vocal sulcus (7), vocal fold atrophy (1), vocal fold scarring (1) as the cause. All cases presented with voice change with few having symptoms of aspiration. Patients were subjected to either vocal fold injection or medialization thyroplasty depending on the etiology and severity, and the outcomes assessed. Majority of our cases showed good amount of improvement on videolaryngoscopy and voice analysis (MPT, VHI scores). Mean MPT scores improved from 7.57 seconds (pre-operative) to 18.83 seconds (final post-operative) and VHI scores changed from a mean of 49.6 to 26.57. Few had post operative problems like vocal fold oedema, under correction, implant malposition. Four patients needed revision procedures due to suboptimal results. Conclusion: Selection of the most suitable procedure for each patient, meticulous and precise technique and adequate follow up will promise best results and minimize complications and undesired results in patients of glottic insufficiency.


Introduction Much discussion has been generated with the introduction of a rule to combat the use of performance enhancing substances and methods in sport. This discussion has been initiated and subsequently became an integral part of the sporting public opinion, as a result of the application of this rule on high profile professional athletes, such as the Greek sprinters Kenteris and Thanou, the British 800m athlete Christine Ohuruogou, as well as FIFA's disagreement to incorporate the rule in its regulatory framework. The "Whereabouts Information" Rule [thereafter WIR] concerns the so-called "non-analytical finding" cases, which do not require a finding of a positive result of an anti-doping test for the application of sanctions on anti-doping rules violations. Instead, they require that the athlete fail to submit whereabouts information and/or fail to be present, for an anti-doping test, during the chosen time and place of his/her whereabouts information. The WIR, therefore, is a prerequisite for a "missed test"; before the sanction of an anti-doping violation could be applied on an athlete and during the analysis the reader must always keep the two together. (1) The consequences, for an athlete, of failing to adopt, apply and follow the WIR are immense. When an athlete fails to submit up to dated whereabouts information or is not where his information states he should be and an officer attempts to test the athlete unsuccessfully, the athlete, according to the World Anti-Doping Code [thereafter WADC], is deemed to have missed the test and he would be the subject of an evaluation of a missed test. Three missed tests in a consecutive period of eighteen [18] months constitute an anti-doping violation, which carries a sanction of ineligibility from all competitions. The historical framework The creation of the WIR dates back to June 2004. It was the International Association of Athletics Federation [thereafter IAAF], that first incorporated such rule into its regulatory framework. This rule came into force in June 2004 and all National Olympic Committees and National Governing Bodies had been notified as to the existence and application of this rule during the last week of June 2004. This was almost 7 weeks before the opening of the Athens Olympiad in August 2004. (2) This Rule came into force for one obvious and well documented reason: that is, to enhance the ability of the sporting governing bodies towards detection of those who attempt to refuse and/or avoid the anti-doping test. Applying the strict liability standard, the result, of the intended aim of the rule, is also obvious: to create an anti-doping violation [in a form of a positive test for performance enhancing substances] even where the athlete has not tested positive for the use of performance enhancing substances and/or methods of enhancing one's performance. Once the legality of such rule has been established, there is little question as to the ethics of its application. Despite the fact that there are concerns as to the serious detriment to an athlete's career if this rule is applied in an arbitrary and capricious way, the aim of its inception and application appears to be defeating all arguments against its use. Once a justification for the ban on doping practices has been established, all arguments on ethicality and morality tend to become weak in rebuttal. I would not argue as to the ethicality or morality of the existence of this rule. To do so, would require me to consider the highly subjective contention of "what is wrong with drugs and doping in sport." The justifications of the ban on doping in sport are well documented elsewhere and another analysis, here, to this effect, would simply leave me repeating the point. What is important, however, for the purposes of this work, is to examine and critically analyse the practicalities of the application of the WIR. It is not only important that gaps in knowledge must be filled, but it is equally important and thought provoking, to enhance practice in this area of sports law. …


In our laboratory, we have attempted to simulate MSW-incineration with a spouted bed combustion system. Our studies show that the combustion of simple chlorinated compounds can lead to some potentially important precursors to PCDDIF. This paper presents results from the lean combustion of 1,2·dichlorobenzene. The effect of equivalence ratio and the chlorine to carbon ratio in the fuel are investigated. Maxima in CE, ORE and PICs are observed as a function of equivalence ratio. The carbon to chlorine ratio influences the chtcrobcnzcne (CB) to chlorophenols (CP) ratio in the products. Measurements in MSW (municipal solid waste) incinerators have shown that polychlorinated dioxins/furans (hereafter PCDD/F) can form heterogeneously in the colder «4500C) portion of the post combustion regions. However, controversies continue to exist about the rates of these processes and the precursors involved. Quantitative knowledge of potential precursor concentrations as well as their rates of formation and reaction is re...


The morphology and the morphogenesis of two hypotrich ciliates, Pseudokeronopsis pararubra sp. n. and Amphisiella annulata, collected from the coastal waters off Qingdao (Tsingtao), China and Nagasaki, Japan were studied using live observation and protargol impregnation. Based on current investigations, descriptions of these two species are provided and comparisons with their congeners are given. Diagnosis for Pseudokeronopsis pararubra sp. n.: Marine Pseudokeronopsis, long elliptical in outline, 180-350x50-90 μm in vivo and dark reddish in colour. Ciliature comprising: 64-92 adoral membranelles; bicorona of 15-26 frontal cirri; 1 buccal and 2 frontoterminal cirri; 7-1 transverse cirri; two midventral rows comprising 62-93 cirri and extending to transverse cirri; 48-79 left and 46-80 right marginal cirri; 5-8 dorsal kineties. Numerous (> 100) macronuclear segments. Two types of cortical granules: one orange-red pigment, mainly grouped around cirri and dorsal bristles; the other, colourless and blood-cell-shaped, lying just beneath the former and densely distributed. The morphogenetic process corresponds well with those of its congeners. The most notable point is that the fronto-midventral transverse cirral anlagen never develop in connection with new oral primordium at posterior portion during divisional process in the proter. Supplementary comparison of Amphisiella annulata with some marine congeners has been provided in this study. Some morphogenetic and reorganizational stages show that its stomatogenesis seems to be similar to that of its congeners, i.e. the oral primordium originates parakinetally from the amphisiellid median cirral row (ACR) in the opisthe, and the old adoral zone of membranelles seems to be retained completely by the proter. Usually only 6 cirral anlagen (including the anlage for undulating membrane) develop. In the proter, the undulating membranes, the buccal cirrus and cirri left of the ACR provides three streaks, other two anlagen derive from the ACR. In the opisthe, the oral primordium produces the anlage for the undulating membranes and very likely three cirral streaks; the other two anlagen also occur within ACR. The new ACR is formed by alignment of the two rightmost cirral anlagen.


In the field of movement disorders, what you see (phenotype) is seldom what you get (genotype). Whereas 1 phenotype was previously associated to 1 gene, the advent of next‐generation sequencing (NGS) has facilitated an exponential increase in disease‐causing genes and genotype–phenotype correlations, and the "one‐phenotype‐many‐genes" paradigm has become prominent.


Substructural Molecular Fragments (SMF) method was applied for computer-aided design of new compounds potentially possessing high anti-HIV activities: tetrahydroimidazobenzodiazepinone (TIBO) derivatives and 1-[2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) derivatives. Using available experimental data, the SMF method was first applied to build QSAR models based on fragment descriptors (atom/bond sequences and "augmented atoms"). The focused virtual combinatorial libraries containing 891 TIBO derivatives and 2640 HEPT derivatives were then generated systematically attaching selected substituents to corresponding Markush structures. Finally, a screening of those libraries using developed QSAR models led to several hits potentially possessing high anti-HIV activity.


ABSTRAK
Relations or relationships are the result of systematic interactions (series of behaviors) between two or more people that have a reciprocal relationship and influence each other between one individual and another individual. Governance is oriented to the synergic relations (relations) between the government, the private sector and civil society (community) in carrying out good and responsible governance. In other words, the relationship between Regional and Private Governments in the management of tourist destinations shows that there is cooperation/ partnership of stakeholders, namely the government, the private sector and the community.
This research method uses descriptive qualitative research. This research uses governance theory from Sumarto. The indicators used include Government indicators as facilitators, Private indicators as providers and service providers and Community indicators as citizens participating in tourism management. This research in the process uses data from observations, interviews and documentation.
The results of this study indicate that there is a relationship between the local government, the private sector and the community in managing tourist destinations in Sei Gohong, this can be seen from the interaction of the three stakeholders. The government as a facilitator who facilitates tourism needs, things that have not been met in the provision of tourism services by the government are complemented by the private sector as providers and organizers of tourism services namely accommodation in the form of lodging (villas) and the community in the tourist areas participate by managing Sei Gohong tourism by the Group Tourism Awareness (Pokdarwis). However, the management of these tourist destinations only involves local governments through the Department of Tourism, Culture, Youth and Sports Palangkaraya City together with the community through the Tourism Awareness Group (Pokdarwis) who are directly involved in tourism management in Sei Gohong. While the private sector indirectly as a provider and service provider because of the impact of the presence of tourism.

COVID-19 infection predisposes patients to a hypercoagulable state. The clinical significance of concomitantly positive antiphospholipid antibodies as a risk factor for thrombus formation is unknown. We report a case of renal infarct secondary to COVID-19 infection with mildly elevated antiphospholipid antibodies. A 71-year- old woman with a history of hypertension, supraventricular tachycardia, resected carcinoid tumor in remission, COVID-19 infection (20 days prior), presented to the hospital with acute onset severe left lower quadrant pain radiating to the left flank for one day. She reported a fever of 101 F. Vital signs were normal in the emergency room. Physical exam showed left costovertebral angle tenderness, otherwise benign abdomen with no guarding or rigidity. Laboratory findings showed normal liver function tests, mildly elevated creatinine at 1.1 mg/dl (baseline 0.8 mg/dl), and leukocytosis (14.2 K/ul). Urinalysis showed no evidence of proteinuria or microscopic hematuria. CT scan of the abdomen demonstrated a large area of patchy hypoattenuation involving the upper pole and interpolar region of the left kidney with adjacent perinephric inflammation representing a sequela of an infarct. Hypercoagulable workup including HIV, hepatitis, ANA, ANCA, complements, B2 glycoprotein, homocysteine, factor V Leiden, anti-thrombin III, protein C, protein S were done. All tests resulted negative except for mildly elevated anticardiolipin antibody, IgM 12.90 MPL (normal 0.00-12.49 MPL). Holter monitor was negative for atrial fibrillation. An echocardiogram did not show any thrombus. Considering her negative tests, renal infarct was believed to be secondary to a hypercoagulable state from COVID-19 infection. Antiphospholipid antibodies repeated 3 months after this admission were mildly elevated. Renal infarction was treated with a heparin infusion and was subsequently transitioned to apixaban. Acute kidney injury resolved with intravenous fluid resuscitation. At a 3-month follow-up, her renal function remained stable with a resolution of symptoms. Renal artery infarct is a possible thrombotic complication of COVID -19. Role of lupus anticoagulant antibodies in increasing this risk warrants further studies.


Reflectance spectra (0.3-3.6 m) of 27 CM2 and ungrouped C2 meteorite powders have been measured, and 9 of them have been identified as possible candidates for thermally metamorphosed CI/CM/CR meteorites based on absence of the 0.7-m band and the 3-m band shape and strength. It was previously shown that heated CM meteorites are better candidates than other CMs for the surface materials on the C, G, B, and F asteroids [1,2] although a significant spectral difference between them in the 2.5~2.8 m region has been recently detected [3]. and QUE 93005) were ground and dry-sieved into powders of <125 m and their bidirectional reflectance spectra (0.3-2.5 m) at 30° incidence and 0° emergence angles and biconical FT-IR reflectance spectra (2.5-3.6 m) at 30° incidence and emergence angles were measured. Reflectance spectra of other meteorites were taken from previous studies [1,2,4]. Shown in Fig. 1 are reflectance spectra of possible candidates for thermally metamorphosed CI/CM/CR meteorites. These meteorite were chosen based on absence of the 0.7-m band [5] and the 3-m band shape and strength similar to those of thermally metamorphosed CI/CM/CR meteorites which were identified through other methods [6-14]. In general, thermally metamorphosed samples easily lose the 0.7-m band, and both the UV and 3-m absorption strengths decrease [2]. Furthermore, the 3-m band of heated CM meteorites tends to lose the characteristic composite shape that includes a stronger band around 2.75 m. Reflectance spectra in Fig. 1 are arranged in the order of increasing heating effect as measured by their optical properties. In order to characterize the 3-m band shape and strength more quantitatively, the following quantities are defined at the key wavelength bands shown in Fig. 2: where R(x~y) indicates averaged reflectance over the wavelength range from x to y m. Then the 3-m band shape and strength are represented by 3-m Band Shape = lnR 2750-lnR 2900 , 3-m Band Strength = lnR 2900-lnR 2600 , which are equivalent to the reflectance ratios in natural logarithm space. Similar reflectance ratios were used by [15]. The above-defined 3-m band shape and strength parameters were calculated from reflectance spectra of 72 CI/CM/CR and ungrouped C2 meteorites. The results are plotted in Fig. 3. It is clearly seen in Fig. 3 that unusual CI/CM/CR meteorites (indicated by U), heated Ivuna samples (open circles), and Murchison samples (open squares) form a region extending from the origin in the lower-right direction, and that …


Objective — to investigate the predictors of cognitive impairment (CI) in patients with CHF and reduced left ventricular ejection fraction of (rLVEF). Materials and methods. The examinations involved 124 patients with CHF aged 18 to 75 years, NYHA II—IV. Cognitive function was evaluated with the use of Mini-Mental State Examination (MMSE), Schulte рrobe, HADS scale. CI counted as MMSE ≤ 26 points. In addition to the standard general clinical examination, the quality of life was assessed with the use of The Minnesota Living with Heart Failure Questionnaire (MLHFQ); physical activity of patients was evaluated by Duke Activity Status Index (DASI) and the 6-minute walking test; immunoenzymometric (determination of interleukin 6, NT-proBNP, insulin), ultrasound diagnostic of endothelium-mediated vasodilatory response of the brachial artery. Statistical methods: descriptive statistics (median, upper and lower quartile), univariant logistic regression, multivariate logistic regression. Results and discussion. CI was observed in 68.5 % of patients and was associated with age (OR 1.07, 95 % CI: 1.03—1.11), duration of CHF symptoms (OR 1.02, 95 % CI: 1.001—1.03), and with the presence and duration of such co-morbidities as AH and IHD (OR 3.46, 95 % CI: 1.44—8.30 and OR 2.60, 95 % CI: 1.14—5.90 respectively). According to the univariate regression analysis, high risk of CI was defined in patients NYHA III—IV (OR 2.68, 95 % CI: 1.22—5.87) with worse quality of life assessed by MLHFQ (OR 1.02, 95 % CI: 1.002—1.04) and with the high ceruloplasmin levels (OR 1.02, 95 % CI: 1.01—1.03). At the same time, lower risk of CD was associated with better functional status (the 6-minute walking test, DASI (OR 0.996, 95 % CI: 0.99—0.999 and OR 0.96, 95 % CI: 0.94—0.99 respectively) and adherence to therapy (OR 0.77, 95 % CI: 0.60—0.98), and also with better endothelium-mediated vasodilatory response (OR 0.9, 95 % CI: 0.83—0.98). According to multivariate analysis, the independent CI predictors in patients with CHF and rLVEF were age, duration of AH, low adherence to therapy and high ceruloplasmin level of blood plasma. Conclusions. Cognitive dysfunction was observed in the majority of patients with CHF and associated with age, duration of CHF symptoms, presence and duration of AH and IHD. High risk of CI have patients with NYHA III—IV functional class, worse quality of life and high ceruloplasmin level. At the same time, the risk of CI developing was lower in the individuals with better functional status (6-minute walking test, DASI), better adherence to the treatment, and better endothelium-mediated vasodilatory response. According to the results of multivariate analysis, independent predictors of CI in patients with CHF were age, duration of AH, poor adherence to treatment and high serum ceruloplasmin level.

Mathematical models with time dependent parameters are of great interest in financial Mathematics because they capture real life scenarios in the financial market. In this study, via the Lie group technique, we analyse evolution-type equations with time dependent parameters and give the general symmetry structure of these equations. In addition, we illustrate this method by looking at an example of exotic options called the power options. Our model parameters are time dependent and the option gives a continuous yield dividend at different time intervals. We present new solutions, satisfying the boundary conditions, to this important problem.

ABSTRACT A series of conjugated bimetallic complexes and their polymeric analogues containing alkyne-functionalized α-coupled oligothiophenes have been synthesized and characterized. The introduction of transition metal centers, with their large variety of ligand environments and oxidation states, can impart interesting physical, optoelectronic and structural properties on these oligothiophene systems. It was demonstrated that π-conjugation of organometallic alkynyl units into the oligothiophene chain offers intriguing models that possess unique features that are not accessible in the classical organic counterparts. The photophysical, electrochemical and structural properties of these classes of metallaynes have been extensively investigated in terms of the type of metal centers and the number of oligothienyl rings within the bridging ligand. The experimental results have also been correlated to the theoretical data obtained by molecular orbital calculations using density functional theory.

712 Abstract 13 Introduction: Achievement of optimal vancomycin exposure is crucial to improve the management of patients 14 with life-threatening infections caused by susceptible Gram-positive bacteria and is of particular concern in patients with 15 augmented renal clearance (ARC). The aim of this study was to develop a dosing nomogram for the administration of 16 vancomycin by continuous infusion for the first 24 hours of therapy based on the measured urinary creatinine clearance 17 (8 h CLCR). 18 Methods: This single-center study included all critically ill patients treated with vancomycin over a 13-month period 19 (group 1), in which we retrospectively assessed the correlation between vancomycin clearance and 8 h CLCR .T his data 20 was used to develop a formula for optimised drug dosing. The efficiency of this formula was prospectively evaluated in 21 a second cohort of 25 consecutive critically ill patients (group 2). Vancomycin serum concentrations between 20 to 22 30 mg/L were considered adequate. ARC was defined as 8 h CLCR more than 130 ml/min/1.73 m 2 . 23 Results: The incidence of ARC was 36% (n = 29/79) and 40% (10/25) in group 1 (n = 79) and 2 (n = 25), respectively. The 24 mean serum vancomycin concentration on day 1 was 21.5 (6.4) and 24.5 (5.2) mg/L, for both groups respectively. On the 25 treatment day, vancomycin plasma clearance was 5.12 (1.9) L/h in group 1 and correlated significantly with the 8 h CLCR 26 (r 2 = 0.66; P <0.001). The achievement of adequate vancomycin serum concentrations in group 2 was 84% (n = 21/25) 27 versus 51% (n = 40/79) – P <0.005. 28 Conclusions: This new vancomycin nomogram enabled the achievement of adequate serum concentrations in 84% of 29 the patients on the first day of treatment.


In order to determine insulin status and beta cell function during the oral glucose tolerance test (OGTT), in impaired glucose tolerance (IGT), 51 such subjects and matched controls, identified during a population survey for diabetes, underwent a 75 g OGTT. Fasting, 30 min and 2 h insulin and intact proinsulin, and fasting and 2 h 32/33 split proinsulin, were measured by specific two‐site immunoradiometric assays. The subjects with IGT had higher fasting (geometric mean ± SD, 5.0 ± 4.0 pmol−1 vs 2.9 ± 1.7, p < 0.02) and 2 h intact proinsulin (23 ± 14 vs 14 ± 12, p < 0.0001), and fasting (3.2 ± 3 pmol−1 vs 1.8 ± 1.8, p < 0.0007) and 2 h 32/33 split proinsulin (18.3 ± 19 pmol−1 vs 6.6 ± 15, p < 0.0001). Despite higher plasma glucose concentrations, the IGT group had similar fasting insulin, lower 30 min insulin (216 ± 124 pmol−1 vs 278 ± 130, p < 0.02), and a lower 30 min insulin/glucose ratio (23.7 ± 2.1 vs 34.8 ± 2.3, p < 0.002). The percentage of fasting proinsulin‐like to total insulin‐like molecules was higher in those with IGT (15.3 ± 8% vs 11.6 ± 8, p < 0.04). After 6 months, at repeat OGTT, the same subjects with IGT were classified as 'persisters' or 'reverters'. The persister (24/51 47.1%), at initial OGTT, had a higher 2 h glucose level, a greater BMI and higher systolic blood pressure, but other parameters were similar to the reverters. In the reverters, when baseline variables were compared to those recorded at six month follow‐up, there was a reduction in 2 h intact (23.8 ± 13 pmol−1 vs 19.4 = 10, p < 0.02) and 32/33 split proinsulin (20.4 ± 18 pmol−1 vs 13.8 ± 13, p < 0.006), and an increase in fasting insulin (41 ± 30 pmol−1 vs 54 ± 35, p < 0.02), respectively, despite no change in fasting glucose. These findings show that IGT is associated with beta cell dysfunction and reduced early insulin secretion during the OGTT. In some subjects with IGT these abnormalities show improvement in the short term.


Business users have a problem in replacing existing business application systems. Well over 50% of all replacement projects fail. The systems have become much too complex and too much knowledge about them has been lost. It is nearly impossible to reconstruct the requirements. Therefore, this paper presents an incremental, integrative approach supported by bridging tools, which allows migrating without requirements. The basic premise is to first breakup the existing systems into separate, collaborating subsystems and then to either convert them, redevelop them or to wrap them one at a time. The key is the interaction of the subsystems with each other and with the database across platform boundaries. The new subsystems can coexist with the remaining old ones until such time that all of them have been replaced.


1the AIDS epidemic has swept the world. In the US, during the intervening 27 years, the demographics of the disease have changed dramatically. What was once a disease of Caucasian MSM has evolved into a disease that increasingly affects women and disproportionately affects people of color. 2 This brief review will examine the demographics of the HIV epidemic as it now exists in the US. Tracking the Epidemic The Centers for Disease Control and Prevention (CDC) has assumed a pivotal role in tracking the spread of the AIDS epidemic. During the early years of the epidemic, the CDC tracked only AIDS cases, defined as: T-cell count less than 200 or development of AIDS-defining opportunistic infections. Given the poor response to HIV therapy in those early years, this method enabled the CDC to estimate with greater accuracy the numbers of people who were infected with HIV because the disease often progressed in a predictable pattern. Beginning in the mid-1990s, however, the era of highly active antiretroviral therapy (HAART) was ushered in with the advent of the protease inhibitors. For the first time, it became possible to control effectively viral replication and forestall the progression of HIV-infested patients to fulminate AIDS. 3


The phase vocoder is a standard frequency domain time-scaling technique suitable for polyphonic audio, but it generates annoying artifacts called phasiness, or loss of presence, and transient smearing, especially for high values of the time-scale parameter. In this paper, a new time-scaling algorithm for polyphonic audio signals is described. It uses a multi-scale Gabor analysis for lowfrequency content and a vocoder with phase-locking on transients for the residual signal and for high-frequency content. Compared to a phase-locking vocoder alone, our method significantly reduces both phasiness and transient smearing, especially for high values of the time-scale parameter. For time-contraction (time-scale parameters lower that one), the results seem to be more signaldependant.

This article considers Landrat books compiled between 1715 and 1720, which contain the results of the last census of homesteads carried out by the Russian state. Even though a comprehensive study of the Landrat books has not been conducted, scepticism prevails when it comes to the reliability of their results. The author argues that there are no grounds for such scholarly scepticism. The materials of the Landrat census have great potential. The reason for distrust of the Landrat data is that they are often compared with the 1710 census, which was badly conducted. Historians also often point out that the transition to the poll tax was caused by the authorities' lack of confidence in the work of the Landrats. However, this was not the case. This transition was due to the fact that the 1715–1720 census made it clear to the government that it had to change the principle and methods of tax collection (to increase taxes).

A growing number of established methods utilising deep neural networks to handle the problem of human motion prediction have been developed as a result of deep learning's success in a wide range of computer vision and computer graphics jobs. Modern motion prediction techniques concentrate on resolving numerous problems to forecast accurately and regular human movement across time. We give a thorough analysis of deep learning-based human motion prediction techniques in this paper. The goal of this work and the human motion prediction challenge are first defined. On the basis of our suggested classification, we then present pertinent background information and a thorough list of motion prediction techniques. Next, we give a thorough analysis of the traits frequently employed in the literature and describe the evaluation procedures. We concluded by providing a quantitative comparison.


THE psychosis to which Korsakoff drew attention includes four prominent features: 1) partial or complete disorientation, 2 ) confabulation, 3) a retention defect, and 4) a variable degree of amnesia, When a polyneuritis coexists with these mental symptcms, a combination which is more commonly noted in chronic alcoholism, the complete picture of the Korsakoff syndrome is present. Although the Korsakoff psychosis is a well delineated entity, its etiology is multiple and diverse. Alcohol is responsible for the majority of cases, but this amnestic-confabulatory syndrome has also been noted repeatedly in patients with various central nervous system infections and in such systemic diseases as malaria, typhoid fever, puerperal sepsis and tuberculosis. It has been ascribed to the actions of poisons such as lead, mercury, arsenic and carbon monoxide. Tarachowl reported three cases of Korsakoffs psychosis among 105 patients with subarachnoid hemorrhage. This uncommon feature of subarachnoid bleeding is more apt to appear a few weeks after onset of the hemorrhage. Some have attributed the appearance of this mental state under these circumstances to the absorption of toxic products of disintegrated blood, but, as Meadows2 indicates, "there must be other factors possibly inherent in the individual." It is this varied etiology of the Korsakoff psychosis that has suggested to some authors, more recently Davidson? that the previous personality pattern of the patient may play a role in the development of this psychosis. Although the occurrence of mental symptoms in patients with brain tumor is common, Korsakoff psychosis in association with a cerebral neoplasm is unusual. Knapp? reporting upon the mental symptoms of brain tumor, quoted Schuster who studied 775 instances of this condition and tabulated only two cases similar to Korsakoffs psychosis. Griintha16 reported this symptom complex in a patient with a craniopharyngioma. In 1941 Benedek and Jubae noted


Abstract Preschoolers' abilities to recognize former caregivers were examined. Participants were 35 children from three preschool classes. Caregivers volunteered in the classes over a 7-week period. At an initial assessment, children were asked to select former caregivers from a line-up of five photographs, and to rank-order the caregivers by personal preference. Recognition was assessed again after 3 months. Although older toddlers performed at chance levels, clear age-related increases in recognition performance were observed, with older preschoolers recognizing 86% of the volunteers at time 2. Younger children responded less consistently over time than older children. Preference for individual caregivers affected recognition performance among younger, but not older, preschoolers. Implications for children's eyewitness testimony are considered.


Proteomics represents the comprehensive study of cellular proteins and is aimed at analyzing their structure, function, expression, interactions, and localization in complex biological systems. The information obtained from these types of analyses can contribute to our understanding of the function of individual proteins by identifying proteinprotein interactions and dynamic protein networks found in normal and diseased conditions. Genomic (DNA) or transcriptomic (messenger RNA) approaches alone do not take into account changes in protein stability, localization, and posttranslational modifications that are often critical determinants of protein function and, by extension, cellular behavior. Although proteomic methods still require significant technical advances to provide a truly "global" or "comprehensive" measure of gene expression similar to that achieved by DNA microarrays, recent advances in proteomics are beginning to provide a means to simultaneously characterize the expression of thousands of proteins in a whole cell or biofluid proteome and hundreds of proteins in select subcellular structures or protein complexes. The information obtained from these studies should promote a better understanding of disease conditions,helptherapeuticdecisionmaking,andpotentiallyfostertheidentificationoftherapeutictargets


Through a program sponsored by the US Department of Energy (DOE), Cummins Power Generation, Inc. (CPG) and Sandia National Laboratories (SNL) have entered into a joint venture to develop and commercialize economically competitive dish-Stirling systems for remote power applications. CPG plans to commercialize 5-kW{sub e} systems that can be used in remote locations for water pumping and village electrification or connected to an existing utility grid. The $14 million Dish-Stirling Joint Venture Program (JVP) is being conducted in three phases over a 3 1/2-year period in accordance with the Cummins Total Quality System (TQS) for new product development. Sixteen systems representing three generations of technology will be fielded and tested. The JVP is being funded equally by CPG, including its industrial partners, and the DOE. Following completion of the program, CPG`s commercialization effort will continue with limited production expected to start about 1995. In this paper, the program plan and technical approach for the JVP is presented. A technical description and current status of the key components and discussions of the key technical issues are also provided. 7 refs.


Vowel formant structure is particularly sensitive to influence from neighboring segments in connected speech. Statistical models can successfully account for acoustic variability from multiple simultaneous sources of variance, such as anticipatory effects of following consonants and vowels (see, for example, Cole et al., 2010). Statistical approaches have also been developed to predict context segments from static measures of spectral variation like mean or midpoint formant frequencies. This study examines shifts in the relative strength of these sources of variance over the course of the target vowel, and compares previous approaches to predicting the identity of upcoming segments with a novel approach which is cumulatively informed by formant frequency variation as it unfolds temporally. Data are from 32 participants who produced target-context word sequences (permutations of …V1C#hV2…, where V1 = [ɛ], C = [θ f], and V2 = [i ɛ ae ɑ u], e.g., "deaf-heating") within a carrier sentence. Timing and prosody were strictly controlled by entraining the syllable rate to a metronome. Context word onset was always [h], which has no intrinsic supralaryngeal articulation and only begins foot-initial syllables in English. This ensured a consistent prosodic boundary between target and context words and prevented resyllabification of C across words.Vowel formant structure is particularly sensitive to influence from neighboring segments in connected speech.

Objective: To study clinical effect of polymeric ceramic inlay restoration of vital pulp posterior teeth with big dentin defect(BDD). Methods: From June 2009 to June 2011, patients in our hospital tooth defect of posterior were greater than 1 teeth cusp had 80 cases, a total of 87 teeth. Digital randomly divided into the treatment group(41 cases, 46) and the control group(39 cases, 43). The control group used with onlays regimen, while the treatment group used with polymer ceramic inlays, compared two groups of one week and one year after the restoration evaluations. Results: After one week of treatment, the treatment group in aesthetics was significantly better than control group. Difference was statistically significant(u= 2.038, P 0.05), comparing the two groups with sensitive and periodontal status and other data. The difference was not statistically significant(u= 1.132, 1.389, all P 0.05). 1 year after treatment, the rank sum test, the treatment group's aesthetic and restoration fracture was significantly better than the control group. Difference was statistically significant(u = 3.138, 2.874, all P 0.05). The two groups' comparison in secondary caries and marginal discoloration, as well as the adjacent shoulder fit and periodontal status and other aspects. The difference was not statistically significant(u = 1.132, 1.374, 1.454, 1.268, 1.366, all P 0.05). Conclusion: Polymeric ceramic inlay restoration of vital pulp posterior teeth with BDD's repairing effect is more significant, patients can resume a greater degree of tooth function, reduce the incidence of secondary caries. It is not easy to fracture and is more beautiful. It is worthy of recommendation.


Abstract Many diseases are associated with oxidative stress are caused by free radicals. Current research has been directed towards finding naturally occurring antioxidants of plant origin. The aim of the present study was to evaluate the in vitro antioxidant activities of methanolic extract of Lawsonia inermis L. bark (MELIB). The present study was carried out for determination of qualitative, quantitative phytochemical and in vitro antioxidant activity for scavenging of free radical DPPH, superoxide radical scavenging and lipid peroxidation. The bark extract is a rich source of secondary metabolites like flavonoids at a rutin equivalent 73.43±0.26%, polyphenol at a gallic acid equivalent 84.70±0.43%, tannins at a tannic acid equivalent 88.75±0.14% and terpenoids at a linalool equivalent 68.13±0.31. MELIB showed free radicals scavenging capacity by way of the DPPH method (6.93±0.51 to 62.63±0.10% inhibition), the superoxide radical scavenging method (1.82±0.41 to 57.11±0.18% inhibition) and the ferric chloride induced lipid peroxidation method (9.87±0.33 to 80.32±0.82% inhibition). The results obtained in the present study indicate that MELIB can be a potential source of natural antioxidants due to the presence of flavonoids, polyphenols, tannins and terpenoids.


Two (100) and two (110) tungsten surfaces have been bombarded with helium ions of selected energies between 5 and 2000 eV. The helium thermal desorption spectra obtained when the targets were subsequently heated at 40 °K/s were used to deduce the fraction of the incident particles trapped in the crystal, and their binding energies. For ion energies ≤400 eV, the fractions trapped were small (~ 1 × 10−3 on the (100) surfaces and ~ 1 × 10−2 on the (110) surfaces) and almost all the trapping occurred in surface-related sites with binding energies ≤ 2.1 eV. For ion energies >500 eV, trapping occurred predominantly in sites characteristic of the bulk material, the sites being created by the incoming ions as soon as their energy was sufficient to produce atomic displacements in the lattice (480 eV). At doses <1 × 1013 ions/cm2, four characteristic binding energies were observed: 2.65, 3.05, 3.35, and 4.15 eV. At higher doses, additional binding states were observed with energies up to 5.4 eV.The results suggest ...


The hippocampus has been shown to play a crucial role in memory and learning. Its volumetry is a well-established biomarker of Alzheimer's Disease (AD) and hippocampal sclerosis in temporal lobe epilepsy (TLE). Manual segmentation being time consuming and suffering from low reproducibility,
robust automatic segmentation from routine T1 images is of high interest for studying large datasets. We previously proposed such an approach (SACHA, Chupin et al, 2007, 2009), based on competitive region deformation constrained by both anatomical landmarks and a single probabilistic template of 16 young healthy subjects registered using SPM5. The atlas being introduced as a soft constraint, robust results have been obtained in large series of patients with various pathologies. In recent years, multitemplate approaches have proven to be a powerful mean to increase segmentation robustness (Barnes et al, 2008) (Aljabar et al, 2009) (Heckemann et al 2006), more specifically for subjects with very large atrophy or atypical shapes (such as malrotations (Bernasconi et al, 2005) (Kim et al, 2012)).We propose here to evaluate the introduction of multiple-template constraints in SACHA.


Nowadays, the data acquisition system is applied in all aspects of production and life, and as an important indicator, the research on the pressure acquisition system is particularly important. This paper proposes a pressure acquisition system that can collect four pressure signals, the sampling rate of a single channel can reach 150Hz, and the range is 30 to 1000 kg. The pressure acquisition system adopts a full bridge sensor, which has the characteristics of good linearity and high sensitivity. The pressure acquisition system can be sampled by the host computer through Bluetooth control. Experiments show that the comprehensive accuracy of the system is lower than that of the current common systems, and the standard deviation of the continuous sampling of the system is less than 0.39, which meets the design requirements.


The purpose of this research is to engage debate about the figure of 'species being' by Marx in his Early Writings , linking it with what he later identified as the 'subjective factor' related to the socialist struggle in Capital-I . Attention to the analysis by Gramsci lays the grounds for discussing an original notion of 'aesthetic consciousness', as developed in a recent Critique of Rationality by the author (O'Brien Brill 2016); as the basis for judgment on which collective mobilization depends. In politics, timing is everything and the socialist struggle takes many forms. Without need for dynamite or cannons, one might suppose that the Gramscian 'cathartic moment' (i.e. an intensely liberating civic energy for change) would surely arise now, a popular opposition see the day, to overcome the grip of Global Capitalist Agencies, allowing a socialist mode of governance to overtake the Western countries, one by one.  After all, class inequality in the West is at astronomical levels (USA Top Bosses earn 347 times the average income of their employees). Why does nothing occur? Are material factors of capitalism's contradictions only necessary but not sufficient conditions for a major social-political shift, because the 'subjective factor' is downplayed in the formula? Generally associated with 'class consciousness', does not material realization of species-being include subjective factors, attention might shift focus to the non-techno-material grounds for radical social change? As Mandel laments in his Introduction to Capital-I, even if apparently planned otherwise, Marx never formally addressed the 'subjective factor'.  While certain of his followers did so at the turn of the 20 th century, since this aspect of project was not clearly laid out by Marx, the tendency has been to emphasize the material factors of concentration and contradiction that constitute the society-fracturing objective yield of unbridled speculative capitalism. Gramsci placed this issue at the center of his writings; rather than wait passively for the critical nexus of material conditions to declenche the inevitable revolutionary shift, might not shrewd political hands set the process in motion and carry it through? This is to assume that more than the ephemeral residue of material events, the Symbolic domain of human collective action is an autonomous source of mobilizing energy, which may lead a movement for change even when material factors associated with the Technical Domain are less than ideal. The purpose of this paper is to explore the role of the 'subjective factor' for revolutionary change, treated as an expanded view of 'species-being; as then taken in hand by Gramsci and others in the battle for change. A general systems model is used to formulate a critique aimed at leaving aside not the material history of societal change, but the dead weight of capitalist past; arguing that there are ways to activate the preobjective intention toward meaning, as basis for judgment of collective circumstance; accelerating movement against exploitation, since the freedom of each depends on the determination of all.


Most of the articles in this issue of Transcultural Psychiatry stem from the 6th annual McGill Advanced Study Institute in Cultural Psychiatry on 'Refugees and forced migration: Human rights and mental health services,' which took place in Montreal, June 1-2, 2006. The conference and workshop brought together an international group of scholars from anthropology, sociology, law, public health, psychiatry and psychology to examine the mental health of asylum seekers, refugees and internally displaced peoples, as well as the impact of human trafficking. Recent years have seen profound changes in the situation of refugees. While the number of people enduring violence and displacement continues to increase, receiving countries have become less welcoming. Anxieties about security and social integration have been used to justify more restrictive migration policies and the harsh treatment of people seeking asylum (Fekete, 2005). In many places, this has resulted in a decrease in the numbers of people applying for refugee status and in people seeking asylum within countries of safe haven. The decrease in numbers could be taken as an indication of less need but, in fact, it largely reflects the impact of policies of deterrence and exclusion. Language: en

The purpose of the following document is not to argue against SAP, but rather provide areas of refinement to fully give shareholders the maximum return. Through extensive case studies and modules, SAP's impact as an ERP system for Airgas, USA LLC was reviewed with the ability to look back two years after its hard launch and almost four and a half years after its initial announcement. Employees have identified several areas of concern that were explored and recommended for improvement. Airgas, like many large firms, find themselves relying more and more on technology to conduct their daily business. The following document compiles examples to support the conclusions that Airgas further customizes SAP to specifically meet their needs and changes a few standard operating procedures to foster a culture of accuracy with the supply chain.


High-resolution contrast-assisted techniques would facilitate differentiation of tissue and microbubble echoes. The authors have found that for the same transmitted time-averaged intensity, the wideband transmission produces an equal or higher received echo intensity from the contrast agent. Thus a wideband imaging scheme could be as effective as the more traditional narrowband technique. In addition, the transmission of wideband high intensity pulses is shown to produce a consistent time domain echo from the microbubbles. This echo is the same whether the bubbles break or remain intact over several pulses. A change in the phase of the transmitted pulse is shown to leave the polarity of the received signal unchanged under a set of experimental conditions.


The format and age of citations appearing in current issues of five aeronautical and aerospace journals are studied. Journal articles were the most highly cited items followed by conference papers, books, technical reports, and dissertations. AIAA papers represented 37% of the conference papers cited, and NASA and NACA reports made up 36% of all technical reports cited in the sample. For all formats, 50% of the citations were from the last 7 years, 75% were from the last 14 years, and 90% were from the last 24 years. The collection management implications of these statistics are discussed.


The authors developed an EMG controlled prosthetic forearm with three degrees of freedom actuated by small size ultrasonic motors. Its weight is less than 700 g and the size is the same as the adult's forearm. The interface between the amputee and the prosthetic forearm was designed on the basis of the fact that the amputee still preserves the phantom limb motor map after amputation. The paper proposes a method to estimate the motion intended by an amputee from the EMG signals using neural network. The method presented can discriminate the amputee's intended motion among six kinds of limb-functions from the multi-channel EMG signals preprocessed by the bandpass and smoothing filters. The cross-information among the EMG signals can be utilized to make the electrode locations flexible, and the band-pass filters can provide the amplitude and frequency characteristics of the EMG signals. The experiments of three subjects and four electrode locations demonstrates that the method can discriminate six motions of forearm and hand from unlearned EMG signals with the accuracy above 90 %.<<ETX>>


: Supply chain 4.0 refers to the fourth industrial revolution's supply chain management systems, which integrate the supply chain's manufacturing operations, information technology, and telecommunication processes. Although supply chain 4.0 aims to improve supply chains' production systems and profitability, it is subject to different operational and disruptive risks. Operational risks are a big challenge in the cycle of supply chain 4.0 for controlling the demand and supply operations to produce and deliver products across IT systems. This paper proposes a voting classifier to identify the operational risks in the supply chain 4.0 based on a Sine Cosine Dynamic Group (SCDG) algorithm. Exploration and exploitation mechanisms of the basic Sine Cosine Algorithm (CSA) are adjusted and controlled by two groups of agents that can be changed dynamically during the iterations. External and internal features were collected and analyzed from different data sources of service level agreements and transaction data from various KSA firms to validate the proposed algorithm's efficiency. A balanced accuracy of 0.989 and a Mean Square Error (MSE) of 0.0476 were achieved compared with other optimization-based classifier techniques. A one-way analysis of variance (ANOVA) and Wilcoxon rank-sum tests were performed to show the superiority of the proposed SCDG algorithm. Thus, the experimental results indicate the effectiveness of the proposed SCDG algorithm-based voting classifier.


This article aims to explain the effectiveness of implementing the project-based learning model along with the questions generated to stimulate the growth of students' high order thinking skills. This study is interesting because it shows evidence that the project learning model has a syntax that can foster students' critical thinking, creative and problem-solving skills. The research procedure was carried out following the flow of quantitative research with an experimental type (pretest-posttest control group design). The research sample was 154 social science students in class XI SMAN 2, SMAN 5 and SMAN 7 Padang. The research instrument is in the form of multiple-choice questions. To analyze the data carried out using the T-test and Analysis of Variance. To determine the effect of implementing the PjBL learning model on the HOTS ability of students in one school, it was analyzed using a t-test with two samples, while analysis of variance was used to determine differences in effectiveness in three schools. The results showed that applying the PjBL learning model to sociology learning in high school was proven to be effective in stimulating the growth of students' higher-order thinking skills.


We monitor directly non-classical transport of quantum-well excitons. The excitons propagate coherently up to four hundreds nanometers, followed by a hot-exciton transport on a length scale of several micrometers at low temperatures.
