In order to manage and rebuild fishery resources, the fishing effort should be controlled effectively. Especially in the setting up of the proper level of fishing efforts, economic standards as well as biological standards must be carefully considered to promote the sustainable and economically viable development of fisheries. This study is aimed to estimate optimal fishing effort of giant octopus by combo fishing which uses longline in Gangwon with statistical data. The result showed that current fishing effort is 28% higher than EMEY. Unit fishing cost for each voyage will be 27% lower and unit fishing profit will be 17% higher than the current situation when the fishing effort meets EMEY. Although current fishing effort is similar to the EMSY, current catching is 16% higher than MSY and 22% higher than MEY.


A combination of anatomical and experimental preparations were used to explore the function of the venom delivery system in rattlesnakes (Crotalus). The distal end of the venom duct is compressed near the point where it empties into the venom chamber, a space surrounding the fang defined by the fang sheath. Within the venom chamber, the inner fang membrane lies obliquely over the base of the fang at least partially occluding the entrance orifice. When the fang is retracted the combination of the compressed venom duct and the spatial position of the inner fang membrane serve to inhibit or block venom flow. As the fang is erected beyond approximately 60° (relative to the roof of the mouth) localized compression of the fang sheath decreases the size of the venom chamber, relieves the compressive force from the venom duct, and displaces the inner fang membrane away from the entrance orifice of the fang. Pressure recordings taken at different locations along the venom delivery system demonstrate that the venom gland produces suction during relaxation of the extrinsic glandular musculature. These findings suggest that the venom delivery system of Crotalus is both more flexible and more regulated than previously assumed. Anat Rec 264:415–426, 2001. © 2001 Wiley‐Liss, Inc.

Bi2Se3−xSx solid solutions, with low x values, were synthesized from melt. The solid solutions were studied in terms of phase purity using powder X‐ray diffraction (PXRD) in order to find the maximum x value for the preservation of the single Bi2Se3‐type phase. The lattice parameters were estimated and showed the reduced unit cell with the S incorporation in the lattice. SEM images confirmed the plate‐like morphology of the Bi2Se3−xSx single‐phase members. The thermoelectric properties (Seebeck coefficient and electrical conductivity) as well as IR reflectivity were also studied on members with x<0.4 that were found to form single phase Bi2Se3−xSx solid solutions.


Various ceramic supports besides standard soda-lime glass have been utilized as substrates for deposition of molybdenum and copper indium diselenide layers (substrate/Mo/CuInSe 2 heterostructures) for application in thin film photovoltaic solar cells. Molybdenum layers have been prepared simultaneously onto the different substrates by electron gun assisted evaporation. Subsequently, CuInSe 2 thin films have been obtained by direct electrodeposition onto the Mo-coated substrates. The influence of the substrate characteristics onto the optical and structural properties of the developed materials has been determined to evaluate the possibility of substituting the commonly utilized glass by ceramics that can wide the applications of these photovoltaic systems. The obtained results indicate that the scattering factor and the structural stress in the layers are minimized when the morphological characteristics of the ceramic are close to those of the standard glass substrates.


Owing to the enhanced mechanical properties of Friction stir (FS) welded alloys are more significant than the
conventional welding process. The primary study was to investigate the influence of process parameters on the
mechanical properties of FS welded metal matrix composite. In order to weld the composite a threaded profile pin
tool (TPP) was used. In the nugget zone numerous small particles and the uniform distribution of refined grains
were obtained and this was depicted by the microstructural characterization. The higher hardness was attained at
the nugget zone compared to that of the base material. A joint efficiency of 89% was accomplished in transfer
direction. The ductile fractures of the Al-Cu matrix and the brittle fracture of the reinforcement particles were
disclosed on fracture surface of specimens


SUMMARY This paper shows a method to represent interval functions by using head-tail expressions. The head-tail expressions represent greaterthanGT(X : A )f unctions,less-than LT(X : B )f unctions, and interval functions IN0(X : A, B )m ore efficiently than sum-of-products expressions. Let n be the number of bits to represent the largest value in the interval (A, B). This paper proves that a head-tail expression (HT) represents an interval function with at most n words in a ternary content addressable memory (TCAM) realization. It also shows the average numbers of factors to represent interval functions by HTs for up to n = 16, which were obtained by a computer simulation. It also conjectures that, for sufficiently large n, the average number of factors to represent n-variable interval functions by HTs is at most 2 n − 5 .E xperimental results also show that, forn ≥ 10,


The proximity formalism is used to study the influence of the surface energy coefficient γ and temperature T of compound nucleus on the half-life of the α-decay process. For this purpose, we perform a systematic study based on the original version of the proximity model. The obtained results of the present investigation reveal that the half-life of the α-decay process reduces by increasing the strength of the parameter γ. Whereas, temperature-dependence of the compound nucleus increases the calculated values of the α-decay half-life.

In 2013-2017, Apple entered into 12 accelerated stock repurchase agreements ("ASR's") through which it repurchased, split adjusted, 693.3 million shares at $102.41 apiece for a total of $71.0 billion. Apple paid $4.023 billion (6.01%) more than if it had just made open market repurchases in those months in lieu of entering into ASR's.

Some might argue that, compared to a tender offer, which requires a steep premium, an ASR is cheap and, given volume restrictions on open market repurchases, a tender offer would have been Apple's only alternative to ASR's. The data does not appear to support that view. Some might say the market could not digest more open market repurchases. The data does not support that either.

ASR's spread cost over time. A company whose future share price is heading higher will find an ASR relatively costly, and that was exactly Apple's experience with ASR's when its share price was in an uptrend.


ABSTRACT As long as the funding mechanism supporting state wildlife conservation relies heavily on hunter-generated funds, declines in hunter participation are a threat to the conservation of both game and nongame species. To address options to bolster wildlife agency profit from the sale of hunting licenses, we developed a stage-based, stochastic population model of a hunter population, and demonstrate its utility within a decision-making framework to inform state wildlife agency decisions. We evaluated hypothetical youth and adult recruitment-focused outreach programs over 10 years to increase license sale profit. Using our model as the core of a decision analysis, state agencies can set hunter population or license profit targets, and evaluate management actions designed to achieve those objectives. We expect that our approach will provide a valuable framework for anticipating the future of hunting and hunting-generated conservation funds, and can be extended to other user groups, including target shooters and anglers.

The flexible material consists exclusively of this armature or comprises a softer material than the matrix component of the composite material of each rigid portion (10) rigid.


The present paper deals with the use of the so-called broken symmetry method for the estimation of the Heisemberg exchange coupling constants. Tetra-nuclear model (square-H4) and chemical (Bis(di-mu-ethoxo-bis(3,5-di-tert-butylsemiquinonato)dicopper(II))) molecules are considered for the analysis. The overdetermination of the problem at hand was exploited to lead to intrinsic relationships between BS energies (independent of spin or exchange couplings). It is demonstrated that only 2 sets of exchange coupling parameters can be obtained from the calculations. The singular values decomposition (SVD) is proposed for the collection of the best parameters that satisfy all linear equations, within modern computers accuracy. Numerical applications as well as the composition of broken symmetry determinants as function of real spin states are discussed.


A request was made of the Separations Technology Laboratory to perform tests to determine the relative effectiveness of Freon 113 and 18% (3.15M) nitric acid on removing dried plutonium nitrate from Hypalon{reg_sign} gloves destined for use in F B-Line. Freon 113 was very inefficient for removing dried plutonium nitrate under conditions of moderate agitation of the liquid in contact with the dried compound. Nitric acid proved to be an excellent agent for decontaminating purposes for both the gloves and for the Pyrex glass. In tests conducted on the glass or on the gloves on which dried plutonium nitrate had not been removed by Freon 113, followup with nitric acid efficiently removed the residual plutonium nitrate. Tests were also conducted to give some measure of the resistance of the Hypalon glove to continuous contact with 18% HNO{sub 3} or with Freon 113. Following two weeks` immersion, there was little physical difference noted from the starting material, except the glove piece immersed in the Freon underwent an 8% weight gain.


At the start of the First Chechen war, the Russian
Federation had recently inherited a fractured polity. New leaders
tried to piece together a new identity and grand strategy for a
state that was still coming to terms with the fact that it was no
longer the center of a union. Its new borders were unstable and
unsecure, and secession of any one republic threatened a potential
chain reaction throughout the region. What Russia needed was a
strong, experienced leader, with a clear sense of direction and
purpose for the Russian Federation. While many factors contributed
to Russia's domestic troubles, Boris Yeltsin proved unequal to the
task of effectively consolidating and directing what remained of
the Russian Republic. In the case of Chechnya, after the collapse
of the Soviet Union the Russian military still retained a vast
arsenal and reserves of manpower, which could have overwhelmed
Chechnya from the outset – had they been well coordinated and
directed. Dzhokhar Dudaev was exactly what Chechnya needed. He had
decades of experience in the ranks of the Russian military and
thoroughly understood their tactics, and he also had experience in
irregular warfare from his service in the Soviet war in
Afghanistan. And, of course, he was very familiar with the
irregular and unconventional style of warfare that traversed
Chechen history. In 1994 and 1995 Dudaev proved his ability to
out-strategize the dysfunctional Russian forces, both politically
and militarily. In 1996, two factors brought him down: the sheer
mass of the Russian forces sent to Chechnya and their tactical
adjustments, as well as undermining from competing Chechen
factions. His death to a Russian air strike in that same year
hamstrung the Chechen government with weak leadership that resulted
in disaster for the nascent Chechen state.Neither the 1994 war nor
that of 1999 was won or lost solely by the actions of one side or
one leader. A mosaic of complex factors, acting on both sides,
contributed to the origins, developments, and outcomes of each war.
Technological, training, and coordinative flaws in the Russian
strategy during the first war were largely rectified in the second.
Additionally, the image of potentially legitimate statehood and
victimization that the Chechens enjoyed at the start of the first
war vanished by the second, causing the republic to lose its badly
needed public support in both Russia and abroad in the
international community. While noting the complexity of factors
involved in the outcome if each war, key individuals at the helm of
each polity created successes and failures out of the assets and
liabilities at hand. Similarities between the origins of each war,
contrasted with the stark differences in how forces executed their
operations and the results they achieved, exemplify the
significance that leadership has on an army's success or
failure.

Dear Editor I read with great interest the article by Dr. Parkman and his colleagues on use of intranasal metoclopramide in your recent issue. They have noticed superior efficacy of the nasal spray form of metoclopramide on total symptom score in diabetic patients, compared with oral tablets, also showing lower rates of side effects. Although the difference between the same dose of 10 mg in oral and nasal forms was statistically significant, the p value was just 0.026 with no report on confidence interval. While response rates between these two doses were compared, one wonders whether there was a significant difference in this relatively small study of 89 subjects divided into three groups (88.9% response rate for oral 10 mg, vs 91.2% for nasal). The authors noted more side effects, particularly nausea, with the use of the oral form. As the major side effect of metoclopramide is drowsiness and other central nervous system-related symptoms, and as these side effects are dose dependent, it is noteworthy that the 20 mg nasal spray had a lower side-effect rate than the oral form of 10 mg. The manufacturer's labeling dose for diabetic gastroparesis is 10 mg up to four times daily, 30 min prior meals or food, and at bedtime. We have formerly presented that doses as small as 2 mg of oral suspension drops of metoclopramide could be as effective as a larger tablet form dosage in control of dysmotility-like symptoms in adults with dyspepsia. The better efficacy of the oral suspension might be correlated with better and more rapid absorption. The same might also be true for nasal spray. In this regard, lower doses of nasal spray could also be tried with probably lower rates of side effects. We note that the problem of cost and the general socioeconomic status of the patients was not addressed in that report. Generally, nasal forms of metoclopramide would likely have a higher cost than its oral forms. In conclusion, before proceeding to recommend nasal spray one should compare this route with oral suspensions, which are much less expensive and more readily available, worldwide.


Endometriosis is common gynecological condition that may arise spontaneously or in surgical scar, particularly of cesarean section, and it may and cause diagnostic confusion with other surgical conditions. Endometriosis can undergo many metaplastic changes, and this is a case report of markedly decidualized endometriosis.


The decomposition characteristics of mussel shell under high temperature and the factors affecting specific surface of calcinated production have been studied by means of differential thermal balance and electron microscope. The results show that the organic matter decomposed during 287 ℃ to 458 ℃. Decomposition of calcium carbonate started at 600 ℃ until 800 ℃ when the reaction was balanced. The morphology characteristics of the calcinated production were distinct at different temperature. The higher the temperature was the smaller the particle size. The calcinated production began to melt when the temperature was at 1 100 ℃. The main factors affecting the specific surface area of the decomposition products have been optimized through orthogonal design with three factors and four levels. The results show that 1 000 ℃,120 μm initial diameter and 1. 5 h holding time were the best preparation conditions.


Results of a numerical study into buckling behavior of cylindrical laminated shell with, and without mid-strengthening subjected to uniform hydrostatic pressure are discussed. Compared with the conventional ring-stiffened cylinder shell, it can greatly improve pressure resistant capabilities of the shell with only small increase the weight. The finite element method based on ABAQUS used to simulate and analyze the buckling behavior of the pressure shell. The model was about 300mm inner diameter, 700mm long and had uniform thickness of 4mm. The buckling pressures were in the range from 0.75 to 1.82Mpa under different parametric of the reinforced structure. The main work and conclusions are mentioned below: (1) Mid-strengthening structure can improve the critical buckling load of cylindrical shell significantly, buckling mode and maximum amount of deformation will both change; (2) The critical buckling load of cylindrical shell with mid-strengthening gradually increases at first and then decreases with increase in ply angles of reinforced layers; (3) When the width of the reinforced stiffener is inversely proportional to its thickness, the critical buckling load also increases at first and then decreases with the increase in widths of reinforced layers. The results of this study can provide a reference for designing similar composite cylindrical shell under external pressure.


In humans, inspiratory constraints engage cortical networks involving the supplementary motor area. Functional magnetic resonance imaging (fMRI) shows that the spread and intensity of the corresponding respiratory-related cortical activation dramatically decrease when a discrete load becomes sustained. This has been interpreted as reflecting motor cortical reorganization and automatisation, but could proceed from sensory and/or affective habituation. To corroborate the existence of motor reorganization between single-breath and sustained inspiratory loading (namely changes in motor neurones recruitment), we conducted a diaphragm twitch interpolation study based on the hypothesis that motor reorganization should result in changes in the twitch interpolation slope. Fourteen healthy subjects (age: 21–40 years) were studied. Bilateral phrenic stimulation was delivered at rest, upon prepared and targeted voluntary inspiratory efforts ("vol"), upon unprepared inspiratory efforts against a single-breath inspiratory threshold load ("single-breath"), and upon sustained inspiratory efforts against the same type of load ("continuous"). The slope of the relationship between diaphragm twitch transdiaphragmatic pressure and the underlying transdiaphragmatic pressure was −1.1 ± 0.2 during "vol," −1.5 ± 0.7 during "single-breath," and −0.6 ± 0.4 during "continuous" (all slopes expressed in percent of baseline.percent of baseline−1) all comparisons significant at the 5% level. The contribution of the diaphragm to inspiration, as assessed by the gastric pressure to transdiaphragmatic pressure ratio, was 31 ± 17% during "vol," 22 ± 16% during "single-breath" (p = 0.13), and 19 ± 9% during "continuous" (p = 0.0015 vs. "vol"). This study shows that the relationship between the amplitude of the transdiaphragmatic pressure produced by a diaphragm twitch and its counterpart produced by the underlying diaphragm contraction is not unequivocal. If twitch interpolation is interpreted as reflecting motoneuron recruitment, this study supports motor reorganization compatible with "diaphragm sparing" when an inspiratory threshold load becomes sustained.


The formation of D‐amino acids (D‐aa's) in many fermented foods depends, among other factors, on the particular fermentation conditions, the action and autolysis of the microorganisms involved. In this sense, the analysis of chiral amino acids is an interesting analytical strategy for food scientists, since these compounds can be used as bacterial markers and can help, e.g., to detect adulterations, microbiological contaminations, etc. In this work, a fast and sensitive method based on MEKC‐LIF has been developed to analyze and quantitate L‐amino acid (L‐aa) and D‐aa in vinegars. The chiral MEKC‐LIF procedure uses 100 mM sodium tetraborate, 30 mM SDS, and 20 mM β‐CD at pH 9.7 as running buffer, obtaining a good separation of the main vinegar L‐/D‐aa previously derivatized with fluorescein isothiocianate. Namely, L/D proline, alanine, arginine, glutamic, and aspartic acid, plus the nonchiral amino acid γ‐aminobutyric acid are separated in less than 20 min with high efficiency (up to 720 000 plates/m) and good sensitivity (LODs lower than 16.6 nM were achieved). Several D‐aa's were detected and quantified in balsamic, sherry, white wine, and cider vinegars using this MEKC‐LIF procedure, observing interesting differences in their L‐aa and D‐aa profiles and contents.


The present study investigated the relationship between local stress fields in austenite grains and variant selections in deformation-induced martensitic transformation in an Fe-24Ni-0.3C (mass %) polycrystalline alloy. The local stress fields in austenite grains were measured by synchrotron radiation X-ray diffraction in SPring-8. We examined the variant selection rule based on the interaction energy between applied stress and shape deformation accompanying transformation (according to Patel and Cohen model). The results indicated that the formed martensite variants had positive interaction energy calculated using either the local stress field measured or the macroscopic tensile stress as the applied stress. The interaction energy criterion using the measured local stress field could show the better correlation with the observed variant selection in deformation-induced martensitic transformation than that using uniaxial tensile stress, although the variant selection was still not completely explained.


OBJECTIVES
This article describes the prevalence of self-reported overweight and obesity, based on body mass index (BMI), by ethnicity and examines the influence of time since immigration within and between ethnic groups.

DATA SOURCES
Results are based on data from two cycles of Statistics Canada's Canadian Community Health Survey, conducted in 2000/01 and 2003.

ANALYTICAL TECHNIQUES
Weighted prevalences of overweight (BMI > or =25) and obesity (BMI > or =30) were calculated by sex and ethnicity for the population aged 20 to 64. Multiple logistic regression models were used to examine associations between overweight/obesity and ethnicity, and within and between ethnic groups based on time since immigration, controlling for age, household income, education and physical activity.

MAIN RESULTS
Aboriginal men and women had the highest prevalences of overweight and obesity; East/Southeast Asians, the lowest. Independent of age, household income, education and physical activity, Aboriginal people had elevated odds of overweight and obesity, compared with Whites; South Asians and East/Southeast Asians had significantly lower odds. Recent immigrants (10 years or less) had significantly lower prevalences of overweight, compared with non-immigrants, but this difference tended to disappear over time.


In this paper, an improved SIFT algorithm with Kernel Principal Component Analysis (KPCA-SIFT) is presented for image registration. Gaussian kernel function is applied to the PCA to extract the principal component for reduced-dimension processing of SIFT descriptor to each feature point. The matched keypoints are selected through similar measure, and the Euclidean distance is replaced by linear combination of cityblock and chessboard distances. The experiments show that this algorithm is robust to image changes in scale, noise and rotation with higher matching accuracy.


1Student, M.E. Structural Engineering, Oxford Engineering College, Tiruchirappalli, Tamil Nadu, India-620009. 2,3Asst. Professor, Department of Civil Engineering, Oxford Engineering College, Tiruchirappalli, Tamil Nadu, India-620009. -------------------------------------------------------------------------***-----------------------------------------------------------------------Abstract Granite powder is an industrial by-product generated from the granite polishing and milling industry in powder form respectively. These by-products are left largely unused and are hazardous materials to human health because they are airborne and can be easily inhaled. An experimental investigation has been carried out to explore the possibility of using the granite powder as a partial replacement of sand in concrete. Twenty cubes and ten beams of concrete with granite powder were prepared and tested. The percentages of granite powder added to replace sand were 5%, 10%, 15%, and 20% of the sand by weight. It was observed that substitution of 15% of sand by weight with granite powder in concrete was the most effective in increasing the compressive and flexural strength compared to other ratios. The test resulted showed that for 15% ratio of granite powder in concrete, the increase in the compressive strength was about 15% compared to normal concrete. Similar results were also observed for the flexure.


Based on the Life Outlook Theory proposed by professor Li Hong from Tsinghua University,the measuring and comparison conducted between Zhaotong's middle school and primary school teachers and the students from Zhaotong Teacher's College on their outlooks of life have shown: in terms of "search for the meaning of life" the teachers have reached an obviously higher level than the students but it shows little difference in their sense of life control and the understanding of life's positive and negative meaning.


A novel approach for designing actively matched laser drivers on MMICs is presented here. The key elements of this approach are to optimize the active matching network of the driver in order to provide good input matching, to maximize the electrical-to-optical transfer function, and also to compensate the frequency response of the laser diode junction current. This provides a flat frequency response in the bandwidth of interest. This approach is demonstrated by design of a 1-4 GHz laser driver.

High annular pressure still happens in tubing-casing annulus (TCA) in early production stage in high temperature high pressure (HTHP) well may due to the thermal expansion of annulus liquid. This pressure will damage the tubing string and casing, besides, it will also have great influence on wellhead and packer. This paper develops numerical method to explain this phenomenon to provide some theoretical guidance for the risk response. Based on the theory of energy transfer in confined space, gas state equation and thetheory of elastic-plastic mechanics, a numerical model is established to calculate the annular pressure in TCA caused by thermal expansion of annulus liquid. Then a wellbore temperature prediction model is established based on the theory of heat transfer through multi-layer thick wall cylinder. By using the model, the trapped annular pressure (TAP) is the decisive parameter to determine the annular pressure. Based on a case well, the influence factors such as reservoir temperature & pressure, setting depth of packer and production rate etc. are analyzed, and the specific properties of TAP in TCA are studied. Referring to the calculation of TAP under the condition of gas-liquid coexistence inside TCA, the influence of gas existing in annulus on the TAP caused by thermal expansion is studied, so as to distinguish it from the continuous TAP caused by channeling flow. The results show that the reservoir temperature has a great influence on the tubing-casing annular pressure.Reason being, in the upward flow process of the production fluid with high temperature, it has transferred a lot of heat radially to the TCA, thus directly improving the TAP. In addition, the design and production stages should be combined to realize the analysis and control of each influencing factor, so as to mitigate the TAP. According to the calculation of the TAP under the condition of gas-liquid coexistence inside TCA, if there is gas in annulus, the TAP will be greatly reduced. Besides, if there is still continuous high pressure in TCA at this time, it means that the wellbore integrity is damaged, and there is gas channeling into TCA, resulting in the generation of continuous TAP. In the field work, the gas also can be injected into annulus to mitigate the TAP actively. This paper builds a model to explain the high annular pressure of TCA. This can help to identify the well integrity. Also, the study on the condition of gas-liquid coexistence in annulus can provides theoretical guidance for mitigating the TAP. This can help engineers get better understanding of well integrity.

Social Bookmarking web sites have recently become popular for collecting and sharing of interesting web sites among users. People can add web pages to such sites, as bookmarks and allow themselves as well as others to work on them. One of the key features of the social bookmarking sites is the ability of annotating a web page when it is being bookmarked. The annotation usually contains a set of words or phrases, which are collectively known as tags that could reveal the semantics of the annotated web page. Efficient and effective search of web pages can then be achieved via such tags. However, spam tags that are irrelevant to the content of web pages often appear to deceive other users for malicious or commercial purposes. There are users who intentionally assign spam tags. Manual detection of such users is very difficult.In this paper, main focus is on the detection of spam users in Social Bookmarking System. Experimental Evaluation is done using ECM PKDD discovery challenge 2008 data set. Experimentation using naive Bayes and K-Nearest Neighbour classifiers on all three Information Retrieval (IR) models (Boolean, bag-ofwords and TFIDF) gives promising results.


This paper presents a real-time guidance scheme for the problem of maximizing the payload into orbit subject to the equations of motion of a rocket over a nonrotating spherical Earth. The trajectory of a rocket modeled as a point mass is considered. The flight is constrained to a path in the equatorial plane while reaching an orbital altitude at orbital injection speeds. It is shown that the dynamics of the problem can be separated into primary and perturbation effects by a small parameter ¿, where ¿ is the ratio of the atmospheric scale height to the radius of the Earth. The Hamilton-Jacobi-Bellman or dynamic programming equation is expanded in an asymptotic series where the zeroth-order term (¿ = 0) can be obtained in closed form. The neglected perturbation terms are induded in the higher-order terms of the expansion. These higher-order terms are determined from the solution of first-order linear partial differential equations requing only integrations which are quadratures. These quadratures can be performed rapidly with the emerging computer capabilty so that real-time approximate optimization can be used to construct the launch guidance law. The application of this technique to flight in three-dimensions is made apparent from the solution presented here.


The results of simulation and measurement of the contact forces of miliwalking HERMES/sup TM/ robot is presented. HERMES is a six-legged miliwalking robot which incorporates high-powered processing, rich sensing and high mobility into a compact body. To develop the kinematics and dynamics of HERMES machine the model of real insect locomotion was used. In the dynamical model two contact-impact models are considered. In the first approach the model was built using general multibody formalism with differential algebraic equation the sign of the constraint force was a test to decide if the respective contact will break or not. This approach implicitly assumes that the contact forces are continuous with respect to time. The general results of the paper concern mainly with this approach. The second approach proposed by Nikravesh (1990) is based on the model which uses the general trend of the Hertz contact law. The dissipated energy in impact is represented by hysteresis form of damping function.

German cinema of the 1990s has been characterised by a wave of domestic comedies unparalleled since the 1950s. These films, dubbed by critics the Neue deutsche Komodie ("New German Comedy"; cf. Kilb), have not only drawn Germans back into the cinema and in doing so, revitalized the German film industry, but they have also given rise to the question of whether these films are the successors to the Autorenfilm (auteur cinema/art film) and the New German Cinema which dominated German film production from the 1960s through the early 1980s. Sonke Wortmann's 1995 hit comedy, Der bewegte Mann (Maybe...Maybe Not), typical of these new situational comedies, grossed over $40 million dollars in its first ten months, making it the third most successful German film since 1980 ("New Pix" 34). Moreover, Der Spiegel has called Wortmann's more recent film Superweib, "eine Erfolgslawine" (avalanche of success) ("Frauen..." 226). These new, self-styled comedies reflect a decided break with the counter-cinema of the Autorenkino of the 1960s and 1970s in more ways than one: not only are they thematically quite different from their predecessors, but they also utilize the narrative constructs of the dominant cinema (cf. Bordwell & Thompson; Bordwell; Bordwell, Thompson & Staiger; Fell; Wollen). Moreover, by emulating Hollywood and the American film industry, the producers of these Neue deutsche Komodien have created a stable of recognizable directors and stars that has brought both glamour as well as commercialization to the German film industry, leaving critics to debate the relative merits of this new, immensely popular yet (as some would argue) aesthetically hollow wave of films. While the German Autorenfilm has often been seen as a manifestation of non-narrative film theory and an alternative to the linear, story-driven commercial film, the rise of the film comedy in the 1990s has contributed to the rebirth of narrative within the cinema and has resulted in the rehabilitation of the story in German cinema. What these new films have in common structurally is their reliance on traditional elements of the classic cinema: causality, linear narrative, closure, and the most necessary element of all, a happy end. These principles are markedly


PURPOSE
This systematic review aimed to evaluate the medium-term (3-year) overall survival and success rates, marginal bone loss and different biological parameters displayed with one-piece zirconia implants.

MATERIALS AND METHODS
Electronic searches were conducted of the MEDLINE (via PubMed), Scopus (Elsevier), Cochrane Library (Wiley) and Web of Science (Clarivate Analytics) databases and manual searching was also performed for relevant articles published up to 14 November 2022. The review included human studies with a minimum of 10 subjects and/or 20 implants and with a follow-up period of at least 3 years after implant placement.

RESULTS
Twelve studies met the inclusion criteria and were included for analysis, giving a total of 1,621 one-piece zirconia implants. Eleven studies were included to perform a meta-analysis of survival rates, and six for success rates and marginal bone loss. The survival and success rates at the 3-year follow-up were 94.4% (95% confidence interval 90.4%-98.4%; P < 0.001) and 91.6% (95% confidence interval 84.2%-98.9%; P < 0.001), respectively, and marginal bone loss was 0.231 mm (95% confidence interval 0.190-0.272; P < 0.001).

CONCLUSIONS
One-piece zirconia implants appear to be a reliable option for restoring missing teeth, obtaining an implant survival rate of 94.4% and a success rate of 91.6% after a follow-up period of at least 3 years. Moreover, the results showed acceptable rates of marginal bone loss and adequate biological parameters.


Metal Buildings with precast concrete or masonry walls (hard walls) have been identified by analytical modeling, shake table tests, and earthquake reconnaissance as being susceptible to collapse. While the steel frames have been shown to be resilient, the potential for wall failure and possible collapse is present. There exists a large stiffness differential between the walls and steel frames, which in turn generates high demands on brittle connections. Also, there is very little coordination between the metal building systems (MBS) engineer and the engineer-of-record who is responsible for the connections, which can result in improper connection design. When these connections fail in a non-ductile manner, the continuous load path is lost and the wall can fall away from the structure. The primary purpose of this research is to develop a new lateral force resisting system that relies on simple energy dissipating connections between the hard wall and the steel frame in order to enhance the global seismic performance and improve life safety. The energy dissipation will be geared in the longitudinal direction (parallel to the ridge) without losing out-of-plane strength in the transverse direction. This research included the development of 3-D models for nonlinear response history analyses. Various connection figurations for friction-slip devices were considered and optimized based on performance, efficiency, and practicality. A case study of one of the 3-D models was performed to assess the appropriateness of the modeling procedure. The 3-D models developed in this research will be used in an ongoing parametric study on the connections to quantify the energy dissipation capacities needed to improve the seismic performance of these structures.

The possibility of quantitative estimation of carboxyl groups in polymers by the dyeinteraction method developed in this laboratory has been investigated. The benzene extract of rhodamine 6Gx from a buffer of pH 10 under specified conditions has been used as the reagent. The estimation has been made by colorimetric measurement at 515 mμ of the color developed by mixing a solution of the polymer in benzene with the reagent. Copolymers of styrene (or methyl methacrylate of vinyl acetate) with acrylic acid, methacrylic acid, crotonic acid, itaconic acid, or maleic anhydride at varying M1:M2 ratios in the 100:1 composition range have been prepared, and the monomer reactivity ratio r1 (which under such conditions becomes equal to the ratio of the mole-per cent of carboxyl in the feed to that in the copolymer) has been determined. The result agrees fairly well with the value of r1 reported in the literature. This indicates that the proposed method is capable of estimating fairly accurately the carboxyl groups or endgroups present in a polymer chain.


This paper examines the Japanese economy in the 1990s, a decade of economic stagnation. We find that the problem is not a breakdown of the financial system, as corporations large and small were able to find financing for investments. There is no evidence of profitabkle investment opportunities not being exploited due to lack of access to capital markets. The problem then and still today is a low productivity growth rate. Growth theory, treating TFP as exogenous, accounts well for the Japanese lost decade of growth. We think that research effort should be focused on what policy change will allow productivity to again grow rapidly. (Copyright: Elsevier)


This paper suggests a ten-step model for solving ethical dilemmas taking into account a wide spectrum of ethical values. The model has a prescriptive content that should help decision-makers to find a solution to ethical dilemmas according to the dictates suggested by moral obligation. For each step of the model, different types of simplification procedures are used in order to guide the decision-maker progressively toward a satisfactory solution. We begin with a discussion of the main characteristics that the model should possess. The paper then gives a detailed description of the single steps of the model. Lastly, a case study was analysed. elected using simple random sampling. The measuring instrument consists of 26 questions based on the SERVPERF model. A total of 200 complete and accurate questionnaires are returned. The relationships among the main constructs of the study are tested using correlational research design. The study concludes that customer satisfaction mediates the relationship between service quality and repurchase intention. It also concludes that SBBM can achieve high levels of service quality and repurchase intention by focusing and investing in the reliability, assurance and empathy factors of service quality. The results of this study are only applicable to the Australian residential market and may not be universally applicable, which is considered a limitation.

This article presents detailed the impact of factors of production on economic growth in the Czech Republic in the period 1994-2015. The main research focuses on the impact of foreign direct investment (FDI) and on answering the question whether between GDP and FDI there is a causality relationship. The VECM model using the impulse responses function confirmed the occurrence of a bi-directional relationship between FDI and GDP in the Czech Republic. According to the empirical evidence, it was confirmed that the consumption demand and trade had a strong impact on GDP. However, these findings demonstrated that a weak FDI had an impact on economic growth.


The recent increase in interest in structural factors contributing to marketing thought development has grown primarily out of the work of the AMA Task Force on Marketing Thought Development. One aspect of marketing thought development briefly discussed but not elaborated on by the task force is the role of "retooling" programs in preparing nonmarketing Ph.D.s for careers in academic marketing. This important topic has received very little empirical investigation. The current study presents the results of an empirical investigation which studied the perception of retooling programs and retooled academics by marketing department heads and chairpersons in the United States. The results bring a clear focus to the role that such programs can play in both marketing education and marketing thought development. They also indicate some of the promise and potential limitations of these programs.

THE most disappointing phase in the roentgen-ray treatment of malignant tumors has been the radiation results in inoperable gastric tumors. No matter what apparatus has been used and no matter what technic has been employed, the results, even in the most experienced hands, apparently have been not only uniformly negative, but in some instances the treatment has seemed to hasten the fatal course. In view of such results it is no wonder that at the present time the consensus of opinion of roentgen therapeutists of wide experience does not favor radiation in inoperable gastric carcinoma, Pfahler (1) says: In general, the intestine and the abdominal tissues will not stand the amount of irradiation necessary to destroy carcinoma of the stomach. We must obtain some addition to our present methods in order to accomplish such results. There is some hope in this direction. Levin (2) declares: In my experience, high voltage X-ray therapy in carcinoma of the stomach has its value only as a post-operative measure, i....

To the Editors: In response to Kuzak and associates' Original Research article on the use of lidocaine and fentanyl premedication for neuroprotective rapid sequence intubation (RSI) in the emergency department (ED), 1 it is well known that laryngoscopy and intubation is very stimulating and can lead to significant activation of the sympathetic nervous system and a resultant rise in intracranial pressure. This knowledge has resulted in the common use of pretreatment agents to blunt this "pressor" response. It is, however, important to realize that the majority of these data have been gathered in the setting of "stable" patients in the non-emergent setting. 2 Many, if not most, emergency patients requiring intubation have borderline physiologic reserve and are often compensating through catecholamine release. Although lidocaine has not been shown to threaten hemodynamics, it has also not been shown to provide clinical benefit.


Relations between Croatia and Slovenia during the first ten years after gaining independence have been dominated by issue of delimitation of international border. In spite of the fact that joint boundary commission managed to resolve disputes along almost entire length of the land border, there are several disputed points remaining as well as unresolved issue of maritime delimitation. Regardless of existing problems, there are favourable conditions to develop intensive cross-border cooperation. Historical inheritance provides fruitful grounds, while population of border regions continously supports cross-border cooperation. Foreign policy aims of Croatia and Slovenia are the same, but two countries have not been equally succesful in fulfilling them. At the moment Slovenia has been much more advanced than Croatia in the Euroepan integration processes.


"Failing to finish..." is a recurring motif in Bunuel's films. In El (released in the US as This Strange Passion), the hero himself is unable to make love. This debility originates in the opening scene, when he falls in love at first sight in a church, his desire being marked by social prohibition and divided between high and low (the woman's feet, the Virgin Mary). Bunuel's genius lies in his invention of appropriate cinematographic forms to represent (rather than illustrate) this case of paranoiac jealousy, thus allowing the spectator to identify both with the sick jealousy of the man and the suffering of the woman. The name Bunuel contains "El," and there is much of Luis in the character of Francisco.


Periodontitis is one of the most widespread infectious diseases that troubled the majority of adults. Human periodontal ligament stem cells (hPDLSCs) have been reported as a promising therapy for the treatment of periodontitis. Melatonin, an indoleamine hormone from pineal gland, has
 various biological activities such as anti-inflammation, anti-cancer and so on. However, whether it is functional in periodontitis is still unclear. The aim of this study was to investigate the effect of melatonin in periodontitis and elucidate the molecular mechanism. Lipopolysaccharide (LPS)
 was used to stimulate hPDLSCs, and viability of hPDLSCs that was treated with melatonin (0, 1, 10, 50 and 100 μmol/L) for 24 h or 48 h was determined by MTT assay. Flow cytometry analysis was carried out to detect the influence of melatonin on cell proliferation. Osteogenic differentiation
 ability of melatonin was determined by Alkaline phosphatase (ALP) assay kit and Alizarin Red Staining. Lastly, western blot was used for the determination of protein expressions related to proliferation, differentiation and ERK/Wnt signaling activity. The results showed that LPS significantly
 inhibited cell viability, which was reversed by melatonin, especially at 10 μM for 48 h and at 50 μM for 24 h. Melatonin (10 μM, 48 h) and melatonin (50 μM, 24 h) notably induced G0/G1 phase cell arrest, increased the expression of CDK2, cyclin E and
 decreased the expression of p27 in LPS-stimulated hPDLSCs. Besides, melatonin significantly promoted cell differentiation through increasing ALP activity, mineralization and protein expressions of Oct4, Sox-2, Runx2 and bone morphogenic protein-2 (BMP-2). Additionally, BMP-2 related ERK and
 Wnt signaling was activated with the treatment of melatonin in LPS-stimulated hPDLSCs. Collectively, melatonin could improve cell proliferation and osteogenic differentiation in LPS-stimulated hPDLSCs, partly through regulating BMP2-related ERK/Wnt pathway.

The November 23rd, 1980 Irpinia-Basilicata (Southern Italy) earthquake is one of the strongest earthquakes ever occurred in Italy. The earthquake was a natural laboratory for the scientific community, which was engaged highly and promptly in investigating the event, thus publishing a flood of papers in different research areas over time. Just these research outputs are the focus of the article, which examines, with a tailored methodological approach, the international and national (Italian) studies started and advanced since the occurrence of the earthquake. First, we built and analyzed statistically two bibliographic databanks regarding the earthquake studies: (a) the international version of IRpinia Bibliographic databASE (IR_BASE_ENG), selecting and standardizing the pertinent scientific documents extracted from Scopus, Web of Science, and other databases and (b) the national version of the database (IR_BASE_IT) using the Google Scholar search engine to search for the most relevant papers in Italian. Second, IR_BASE_ENG was analyzed in a bibliometric perspective through the data mining VOSviewer software (Waltman et al., 2010) that builds co-occurrence term maps useful in perspective of investigating the wide-ranging studies on the earthquake. Third, taking a cue from this network analysis, we recognized the main research topics and performed a minireview of the related international studies, integrating in it a quick reference to the literature in Italian. Finally, we associated the scientific outputs to each cluster/topic, also performing the frequency analysis of the published documents for each subject, thus gaining information on the temporal trends of studies and getting a more exhaustive evidence of the scientific landscape on the earthquake over the last 40 years.


Objective: Candida albicans,is one of the most resistant pathogens found in root canals with necrotic pulp and in recurrent root canal failure cases. Removal of this resistant microorganisms from the root canal poses a special challenge by routine instruments and conventional irrigants. The objective of the study is to compare the anti-fungal efficacy of Garlic extract (Allicin) with two most commonly used root canal irrigating solution (3% NaOCl) Sodium hypochlorite and (2% CHX) Chlorhexidine gluconate through specific methodology that can project Garlic extract as an antifungal irrigant of choice. Garlic extract showed definite antifungal activity against candida albicans, but with lower level than sodium hypochlorite and Chlorhexidine. Chlorhexidine showed greatest antifungal efficacy out of the four agents tested

This paper presents a study of relationships between climatic factors favoring outbreaks of the Fusarium oxysporum f. sp. vanillae (FOV) within a shade-house installed at the Veracruz State, Mexico. The relationship between temperature (T) and relative humidity (RH) within four predefined specific zones inside the shade-house were mainly studied and analyzed by using compiled data from 2010 to 2014 during different periods of the year. T and RH sensors were installed in such specific zones to determine the difference of the behavior of both parameters during particular periods of the year. Derived from the analyses of the compiled data and from reported literature, a set of rules were built to express ranges of T and RH that favor the fungus outbreaks. Such rules were represented quantitatively and qualitatively to facilitate their interpretation. Quantitative data were transformed into qualitative data using a fuzzy logic approach. The results showed important relationships between the behavior of T and RH with FOV outbreaks depending on different zones of the shade house and on particular periods of the year. Most of the occurrences of FOV were detected within the zones that showed lower temperatures and higher relative humidity (zones Z3 and Z4), where most of the sanitation actions occurred (70%). Zone Z1 was the one with higher temperature and lower relative humidity, which resulted with less occurrences of fungus outbreaks. It was recommended to monitor the variables T/RH in different zones inside the new shade houses to be built and avoid enclosing the shade-house by hills that could block the sunlight and produce runoffs of water, thus contributing to increase the humidity of the installation.

This research aims to analyze the effect of economic value added, inflation, net profit margin, and dividend yield on stock returns with company value as a moderating variable either partially or simultaneously. The research scope is coal sub-sector companies that is listed on the Indonesia stock exchange (BEI) for the period 2015-2021, using purposive sampling technique, 6 companies were obtained as research samples. The analysis technique that is used are multiple linear regression analysis and moderate regression analysis. The results are partially only the Net profit margin variable that has significant effect on stock returns, while the Economic value added, inflation, and dividend yield variables have no effect on stock returns. In addition, firm value as a moderating variable proved unable to strengthen or weaken the relationship between Economic value added, Inflation, Net profit margin, and Dividend yield on stock returns. Simultaneously, all variables have no effect on Stock Return.


This study focuses on Ferruccio Busonis magnum opus his unfinished opera Doktor Faust , which he had worked on from 1916 until his death in 1924. Busoni addresses his compositional descendents, the unborn to whom he has bequeathed his legacy. The structural use of the circle in Doktor Faust is connected with Busonis speculations about the omnipresence of time. It seems possible that Busonis opera may communicate simultaneously in two different temporal spaces the first, in linear time, as the unfolding of sequential dramatic scenes, and the second, outside of linear time, as a circle of internal connections, inaudible but discoverable. If the Kabbalistic model of Doktor Faust is to be upheld, it must be consonant with Busonis practice of adapting architectural structures to musical form. The study also includes bibliography that presents a list of reference articles for the study. Keywords: Doktor Faust ; Ferruccio Busoni; Kabbalistic model; legacy


Facing constraints to meaningful caring emerged as a significant aspect of the experience of caring explored in a larger hermeneutic phenomenological study of family practices, before, during and following the admission of an older relative to a nursing home. Hermeneutic analysis of in-depth interview transcripts and observation field notes of 14 family carers' experiences disclosed six shared meanings: (i) being out of control; (ii) not being heard; (iii) experiencing barriers to sharing care with staff; (iv) feeling adrift, excluded and disempowered; (v) wanting to engage in caring partnership; and (vi) living in a constant state of anxiety. Concern is illuminated in the narrative of family carers' experiences of being misunderstood, and attempting to manage constraints imposed by institutional rules and care routines which threaten the quality of existence for themselves and their relatives. This paper challenges nurses to increase their awareness and acknowledgement of the importance of creating a context of care in which family carers may feel empowered to engage in meaningful caring activities and relationships.


We propose a chaos time-domain reflectometry (CTDR) for locating faults on live wires. This method uses a chaotic output of an improved Colpitts oscillator as probe signal, and detects wire faults by correlating a duplicate with the echo of the probe signal. Benefiting from the anti-jamming of the correlation function of the wideband chaos, fault location on live wires can be achieved. We experimentally demonstrate the detection for live wires in a digital communication system, in which a type of digital signal named high density bipolar of order 3 (HDB3) is transmitted. The effects of the chaotic probe signal on the bit error rate (BER) of the transmitted HDB3 at different rates are analyzed. Meanwhile, the influences of the backward HDB3 reflected by wiring faults on the signal-noise-ratio (SNR) of CTDR measurement are examined experimentally. The results show that fault detection on live wires is achieved when the power of the chaotic probe signal is about from -24.8 dB to -13.5 dB lower than that of the transmitted digital signal. In this case, the BER is kept less than 3E-10, and the SNR of CTDR is higher than 3 dB. Besides, the auto-correlation properties of the improved Colpitts oscillator at different states are investigated experimentally to explore the suitable chaotic states for the CTDR.

As the pillar cornerstone industry of national economy, petroleum industry is developing and expanding year by year rapidly. However, most enterprises have paid little attention to logistics as the promotion of core-competitiveness. Logistics in petroleum industry play a very important role in national energy sources security resources distribution optimization and cost reduction and profit increase. In this essay, the author analyzed the status quo of logistics in petroleum industry and give suggestions on the development of logistics in petroleum industry in the long run.


Since early in the twentieth century, two distinct upper canine morphologies have been assigned to the fossil hominoid Sivapithecus from the Siwaliks of Indo-Pakistan. The canine sample as a whole has been critically important in conceptions of Sivapithecus taxonomy and paleobiology. Some specimens of one canine type are associated with other dental and gnathic material of Sivapithecus, whereas all specimens of the other type occur as isolated teeth. One unusual feature of all of the latter specimens is the lack of a distal wear facet, even on teeth with an extensive mesial wear facet showing that the teeth were in functional occlusion. This condition is never found in the upper canines of extant anthropoids, indicating that the canines of the second type have been misidentified as hominoid teeth. Comparisons with the canines of other mammals revealed that they are in fact the canines of female suids. Removing these canines from Sivapithecus calls into question one recent taxonomic revision of the genus that argued for time-successive species of Sivapithecus based on the perceived temporal segregation of the two canine morphologies. It also alters certain perceptions about canine sexual dimorphism in Sivapithecus. Jay Kelley.

When I first open a new document on my computer, as I have just done, the relationship between my key presses and what happens on the screen is rather loose. I press Enter a few times to move the cursor down the page a bit (allowing some ready space to fill in the title later), and sometimes nothing happens for a while; or the cursor disappears for a few seconds before reappearing in its new position. After a minute or so, the machine seems to settle down, and then the correlation between taps on the keyboard and movements on the screen becomes much tighter and more consistent. Then, because taps and movements are tightly and predictably coupled, it hardly seems an inference (or imputation) at all to see the taps as the causes of the changes on the screen. While the computer is still 'waking up', I imagine that the taps are still the causes of the screen changes, but that the temporal relationship is lengthened and muddied by the fact that there is a lot else going on inside the machine while it is, so to speak, finishing dressing and cleaning its teeth. If, however, the machine was not just sleepy and preoccupied but seriously ill, then the relationship between taps and screen changes might become so bizarre and inconsistent that I would assume that causality had broken down. There may be causal connections inside still — the machine may still be operating in a completely deterministic fashion — but as I can no longer make sense of the relationship between input and output, I withdraw the imputation of causality. Just so with myself. There is abundant evidence that I impute causal relationships between bits of my experience — my imagining a calm meadow and a physical feeling of relaxation; the thought 'I'd better get up now' and the act of getting out of bed — on the basis of a sufficient tightness of coupling between the events, and whether their conjunction makes sense in terms of the causal narratives through which I habitually interpret my experience. I ask myself, preconsciously for the most part, a number of questions, and on the basis of the answers, I either do or do not make that causal attribution. Is A reliably followed by B? Do


Pollen tube development is slower depending on species and varieties, and in this process, it can lose ovary viability under some conditions. For this reason, this study was carried out by considering how the pollen performances of the 4 apricot genotypes gained to Turkey and to the world by selection breeding reacted with some chemical applications and these reactions would be a basic knowledge in advanced breeding studies. In the study, pollens of Güzeriği, Mahmudun Eriği, Eğri Çiğit and 158 genotype apricots genotypes were used which were selected from Erzincan province. These genotypes were counting pollen amounts. The influence of some chemicals on the pollen germination and tube growth 4 apricot genotypes were investigated. For this, 10 ppm gibberellic acid (GA3), 50 ppm potassium nitrate (KNO3), 5 ppm indole acetic acid (IAA), 25 ppm boric acid were added to the control germination medium. Control medium containing 1% agar and 10% sucrose was used as the control germination medium. As a result, the effects of growth regulators and minerals on the pollen germination and tube growth were differed according to the genotypes. Boric acid applications have increased both the pollen germination and the length of the pollen tube.


In this paper we construct a new, previously unknown four-parameter family of complex Hadamard matrices of order 6, the entries of which are described by algebraic functions of roots of various sextic polynomials. We conjecture that the new, generic family G (4) 6 together with Karlsson's degenerate family K (3) 6 and Tao's spectral matrix S (0) 6 form an exhaustive list of complex Hadamard matrices of order 6. Such a complete characterization might finally lead to the solution of the famous MUB-6 problem. 2010 Mathematics Subject Classification. Primary 05B20, secondary 46L10.

ANNIE ERNAUX'S LA HONTE (1997) is a semi-autobiographical work in which the author explores how a traumatic memory is stored and frozen in the mind.' Her reflection is built on the assumption that memory can never be truly authenticated since traumatic experience precludes direct access to testimony. "Il n'y a pas de vraie mémoire de soi" (37). Consequently her attempt to remember things past, the adolescent youth of the summer of 1952 as "little Annie D," constitutes a quest for understanding unimpeded by the imposition of an artificial reality. "Naturellement pas de récit, qui produirait une réalité au lieu de la chercher" (38). Based on the premise that language puts memory into question, it reflects, however, on the manner in which one perceives the world and takes hold of one's life story however elusive it may be. "Ce qui m'importe, c'est de retrouver les mots avec lesquels je me pensais et pensais le monde autour. Dire ce qu'étaient pour moi le normal et l'inadmissable, l'impensable mÃame" (37). What Emaux recognizes must remain an incomplete narrative nevertheless affords her the possibility of engaging in a cognitive performance capable of unraveling unassimilated memory. In so doing, Ernaux's story suggests that the initial shamefulness prompting her to find the words to "dire l'inadmissible" also entails, and perhaps even requires, the provisional adoption of a mask of shameless normality and invisibility ("dire Ie normal"). Until Emaux is able to do this she cannot let herself feel authorized to take pleasure in being the object of the gaze without the accompanying fear of experiencing affective confinement. At the core of Ernaux's writerly quest is the desire to describe the etiology of her perception of shame. She situates the birth of this feeling in an event of domestic violence that she witnessed in June 1952. "Mon pà ̈re a voulu tuer ma mà ̈re un dimanche de juin, au début de l'aprà ̈s-midi" (16). This scene of primitive violence revealed the dark forces that fatally marked her existence as being flawed and committed her to an interminable feeling of malaise. Trauma, which literally signifies "injury" or "wound," signals, as Freud has suggested, a situation of helplessness and the anxiety that it produces. Victim of an affective paralysis, Emaux lived with a story that she was unable to put into words. "J'ai toujours eu cette scà ̈ne en moi comme une image sans mots ni phrases" (17). The image of violence imprinted on the mind's eye makes evident the act of bearing witness as well as its failure to be articulated

More than a year ago, the enterprises of the Eurasian Recourses Group (Eurasian Group), the Republic of Kazakhstan, launched the introduction of a production system, which we called the ERG Way. This is the way to increase the efficiency of the company and its processes, not only production, but also all related — management, processes related to purchases, repairs, financial operations. The ERG Way project is a strategic one, and the group's management has high hopes for it, expecting tangible results from its implementation, including financial ones. But the most important goal of the production system is to change the company's culture, creating conditions for employees in which they will not only work comfortably and safely, but also improve their own and the enterprises ' efficiency on a daily basis.


Introduction: Carotid endarterectomy significantly reduces the risk of cerebrovascular events in both symptomatic and asymptomatic patients with significant carotid stenosis. The recent American Heart Association/American College of Cardiology guidelines advise that carotid endarterectomy is only beneficial when the perioperative stroke or mortality rate is below 6%. The aim of this study was to review the results of carotid endarterectomy performed in Malta by one vascular surgeon. Methods: All patients undergoing carotid endarterectomy between July 2007 and June 2011 were included in the study. Data was entered prospectively into a vascular database. Retrospective review of the case notes of all patients undergoing carotid endarterectomy was also performed. Demographics of the patient cohort as well as information about perioperative mortality, cerebrovascular events, cardiac events as well as any other complications were recorded. Information was also collected about any deaths and cerebrovascular events during the follow up period. Results: 51 patients underwent carotid endarterectomy during the study period. 94% were symptomatic (65% CVA; 15% TIA; 10% amaurosis fugax; 4% TIA and amaurosis) and 6% asymptomatic. 46% had an internal carotid artery stenosis of 90% or more while the rest had a stenosis of 70% or more. 31% of patients also had significant contralateral carotid stenosis or occlusion. There was one postoperative mortality (1.9%) and one patient sustained a postoperative lacunar stroke (1.9%). There were no cranial nerve injuries and no bleeding requiring return to theatre. The combined perioperative mortality and stroke rate in this cohort was 3.9%. Conclusions: The combined perioperative mortality and stroke rate in this sutdy is better than that reported in the major randomised controlled trials. The perioperative death and stroke rate is well below the threshold level advised by the AHA/ACC.


This paper provides an overview of the emergent public health risks attributable to air pollution in Lagos and solutions to reduce them. Growing evidence has substantiated a causal relationship between air pollution and mortality, hospital admissions for respiratory or cardiovascular disease and an associated increased risk of myocardial infarction. Lagos, the former capital of Nigeria with a population of 15 million has been identified as one of the fastest growing megacities with annual mean concentrations many times higher than the thresholds recommended by the WHO. Given the urban conglomeration of Lagos, this paper shows that differential traffic density, socio-economic conditions, access to healthcare and proximity to sources of emissions create differential susceptibility of communities to ill health attributable to air pollution, especially within vulnerable groups including children, the elderly and pregnant women. The paper therefore argues that an understanding of the scale and spatial variation of air pollution is not sufficient for reducing the risks posed to public health. An effects-based approach needs to be adopted in order to frame air pollution problems in the city within a public health context, rather than as an environmental nuisance.


R-curves, fracture resistance (K R ) as a function of crack extension (Δa), of a gas-pressure sintered monolithic Si₃N₄ were determined by controlled flaw/strength technique. Rising R-curve behavior was observed, confirming the operation of microstructural toughening process during crack growth. The R-curve parameters, k and m in the equation, K R =k(Δa) m , were determined to 30.301 and 0.1146, respectively. Microstructural observation of growing crack revealed that the bridging in the crack wake by unbroken ligament of large elongated β-grains was the mechanism primarily for the rising R-curve behavior.


As demand for more hydrological data has been increasing, there is a need for the development of more accurate and descriptive models. A pending issue regarding the input data of said models is the missing data from observation stations in the field. In this paper, a methodology utilizing ensembles of artificial neural networks is developed with the goal of estimating missing precipitation data in the extended region of Chania, Greece on a daily timestep. In the investigated stations, there have been multiple missing data events, as well as missing data prior to their installation. The methodology presented aims to generate precipitation time series based on observed data from neighboring stations and its results have been compared with a Multiple Linear Regression model as the basis for improvements to standard practice. For each combination of stations missing daily data, an ensemble has been developed. According to the statistical indexes that were calculated, ANN ensembles resulted in increased accuracy compared to the Multiple Linear Regression model. Despite this, the training time of the ensembles was quite long compared to that of the Multiple Linear Regression model, which suggests that increased accuracy comes at the cost of calculation time and processing power. In conclusion, when dealing with missing data in precipitation time series, ANNs yield more accurate results compared to MLR methods but require more time for producing them. The urgency of the required data in essence dictates which method should be used.

SUMMARY The order statistics of independent random variables each having the same negative binomial distribution are discussed. Recurrence relations for probability generating functions and moments of the distributions of the order statistics are given. These have been used to provide tables of the expected values of the order statistics. Finally, two limiting distributions are presented and moment approximations based on one of them are evaluated.


Compilation of the percentages of pine and spruce pollen from throughout northeastern and north—central North America shows that at the present time pine exceeds 10% in the tundra, forest/tundra transition, and boreal forest, and that spruce percentages are generally higher than pine in these areas except in Manitoba. The conifer—hardwood forest has much more pine pollen, especially to the west, and it has very little spruce. In the deciduous forest, pine pollen is generally less than 10%, and in the prairie only a few percent. The late—glacial spruce zone of New England may record a vegetation similar to the boreal forest of today, which contains Pinus banksiana, but the evidence indicates that in the Great Lakes region pine trees were absent. As a result of the climatic change that set off the rapid retreat of the ice sheet from the Great Lakes region, starting about 12,000 years ago, the peripheral spruce forest rapidly deteriorated. The spruce was replaced in south—central Minnesota by birch and alder...

A primary cell culture system was developed to study the epidermal growth factor (EGF) receptor in the fetal bovine mesonephros and its urogenital derivatives. Radioreceptor assays demonstrated EGF binding as early as Day 37 in mesonephric cells and in cells derived from the fetal reproductive ducts, gonads, and metanephros--all mesonephric derivatives. Immunocytochemical studies revealed that EGF receptors were localized in the ductal and tubular epithelium of these urogenital organs. EGF induced DNA synthesis and tyrosine phosphorylation in the bovine mesonephric cells, suggesting that EGF receptors detected in these cells were functional. In addition, transforming growth factor alpha, the putative fetal ligand for the EGF receptor, was found to specifically compete for EGF binding to the receptor, as well as to induce DNA synthesis in a manner similar to that of EGF. Estrogen did not regulate EGF receptors or specifically bind to bovine mesonephric cells. The development of estrogen receptors in the bovine species occurs markedly later than that of the EGF receptor, in contrast to the mouse, where both receptors are observed at very early stages of reproductive tract development.


The QUEST model of question answering is a computational-cognitive model designed to describe a person's mental narrative comprehension process, which predicts behavioral responses to openended questions about the narrative. The model is based around a QUEST knowledge structure, a directed graph that captures the story's events and the causal and goal-oriented relationships between them. We present a family of computational methods to transform an automated planning narrative knowledge representation that has been successfully used for computational narrative generation, to a QUEST knowledge structure. We then report an experiment to test the hypothesis that these plan-driven knowledge structures have a meaningful relationship with a story consumer's comprehension of a narrative. The results help advance a research agenda that uses cognitive states as the target of computationally generated narratives.


The shape of the Fermi surface of topological nodal-ring semimetals at low carrier concentrations is characterized by the ring radius b/ħvF. This peculiar topological property may not have a clear signature in measurable physical quantities. We demonstrate an accurate and definitive method to determine the radius of topological nodal-ring semimetals. Under a magnetic field along the ring axis, the axial magnetooptical response (σzz) has a giant peak. The position of this ultrastrong response is at the frequency of exactly 2b and is independent of the strength of the magnetic field. The amplitude of the peak response is many times stronger than that of any other inter-Landau level transitions if the magnetic energy is greater than b and is similar strength if b is greater than the magnetic energy. The origin of the ultrastrong response is that the axial magnetic transition is governed by selection rules completely different to those governing σxx where the giant response is absent [R. Y. Chen et al., Phys. Rev. Lett. 115, 176404 (2015)]. The present work provides a method to accurately determine parameters of the topological properties of semimetals.

Korean hemorrnagic fever (KHF) was given a world-wide attention during the Korean war when about 3,000 KHF cases occurred for the first time in Korea among the UN troops, although some similar diseases had previously been reported from Russia, China and other areas of Europe. Recently in Korea several hundred patients were haspitalized annually due to KHF, and in China forty thousand people suffered from hemorrhagic fever, and man occurreces were reported also in Russia, Scandinavia and Japan. In 1967, Lee & Lee reported the isolation of Hantaan virus, the erioiogic agent of KHF, from the patients and .Apodemus agrarius coreae, and in 1978, Lee et al deveiopea the method of serological diagnosis of KHF. The working group on Hemorrhagic fever with renal syndrome at WHO meeting in Tokyo in 1982 recommended that diseases similar to KHF with different names should be referred as "Hemorrhagic fever with renal syndrome (HFRS)." Yet there is na repon on the physico-chemical properties of Hantaan virus but with the Lee's fluorescent antibody technique, the study of the properties of Hantaan virus is possible. The effects of chemicals on Hantaan virus were examined for the first time with rissue cultured cells and Apodemus agrarius coreae. The results are summarized as follows: 1.The infectivity of Hantaan virus was contained in RNA component. 2. The lipid-solvents such as sodium deoxycholate, ether, chloroform, aceton and benzene rapidly destroyed the infectivity of Hantaan virus. 3. Chemical disinfectants such as ethanol, HC1, NaOH. & iodine solution easily destroyed the infectivity of Hantaan virus to the Apodemus agrarius.
