It is one important characteristic of Chinese ancient literature and art criticism that critics expressed their aesthetic feeling in terms of taste (Wei or Quwei). Up to now, The study of "Wei(taste)" and "interest(Qu)" in Chinese ancient poetic criticism caused more attention than that in Chinese traditional opera criticism. "Wei(taste)" and "Qu(interesting)" has two meanings in opera criticism. One is the meaning of popular sense and vulgar interesting; the other is of the "aesthetic state (Jingjie or Yijing)". This paper gives an overall analysis of the features and relations of "Wei (taste)" and "Qu (interesting)" theory in Chinese traditional opera criticism, explains the continuous development, and illustrates main concept of Chinese traditional opera aesthetics.


who is most manifest. The book is divided into two parts – history and legacy – with the former twice the length of the latter, for, as Cameron says in her preface, there is little that can be taken for granted in telling the history of Byzantium. The first part is a marvel of conciseness: Cameron evokes a sense of the Christian Empire of Byzantium from 330, and the foundation by Constantine of his city on the site of ancient Byzantion, to the fall of the city ('Istanbul') to the Ottomans in 1453. To those who know, the depth of Cameron's learning and her insight will be manifest; to those who don't, they can be assured that the account is accurate. The second part is more questionable. From the beginning, Cameron is concerned to emphasize that Byzantine Christianity is not the same as 'Orthodoxy', but, to my mind, she doesn't make very clear what the differences are. The picture is, perhaps inevitably, somewhat external, and so she is reluctant to evoke what Byzantine Christianity means and tends to concentrate on things. The chapter on 'The setting of worship' closes with a couple of pages on 'Religious objects', and begins, 'Museums and collections are also full of objects' (p. 94). But is it really to museums and collections that we are to go to find out about the legacy of Byzantium, rather than to the living communities indebted to Byzantium? The rest of the chapter is about church buildings, icons and relics – again things. Although we are told several times that the Orthodox call the Eucharist or Mass the Divine Liturgy, there is not a word on what happens in that service or what is distinctive about it. Cameron talks about canon law and its importance, which is good (though the Orthodox speak of the 'holy canons'), but, even though she mentions monasticism and Mount Athos, there is nothing about spiritual fatherhood, which is a prominent feature of Orthodox life today for many Orthodox. What Cameron does give us is a sympathetic picture of orthodoxy as it appears to a learned outsider. We Orthodox might learn a lot from it.


The conformation of the N—H bond in the structure of the title compound, C7H7Cl2NO2S, is nearly syn to the ortho-chloro substituent, similar to the syn conformation observed for the N-(2,4-dimethylphenyl)methanesulfonamide. The geometric parameters are similar to those in other methanesulfonanilides, except for some differences in the bond and torsion angles. The amide H atom is readily available to a receptor molecule during its biological activity, as it lies on one side of the plane of the benzene ring, similar to those in other N-arylmethanesulfonamides. The molecules are packed into chains through both N—H⋯O and N—H⋯Cl hydrogen bonds.


Proton elastic scattering at energies around 2.0 MeV was used to determine the concentration of oxygen in a Y-Ba-Cu-O compound, nitrogen in a TiN film on steel substrate, and carbon and oxygen in a thin Mylar film. Proton scattering from light elements in this energy range exhibits non-Rutherford scattering cross section, which is enhanced by a factor of 4 to 7 relative to the Rutherford scattering cross section. Thus the sensitivity for the light element detection is considerably larger than that obtained by He~+ ion scattering. Quantitative analysis by proton scattering is discussed and compared with other methods.


The greeting words are a set of words, morphemes, phrases or expressions, being utilized to greet or start a conversation with the other person in a language event. The greeting word can be categorized as an element of language that is crucial in communicating since the existence of greeting words helps us in terms of recognizing to whom the speech is intended. It can be seen from one of the processes of social interaction that takes place in the Mojosari public traditional market environment. Thus, the formulation of the problem in this study are (1) how the greeting words are used by sellers and customers in the Mojosari Public Traditional Market (2) how the greeting word functions are utilized by sellers and customers in the Mojosari public traditional market.
The employed method in this research was descriptive-qualitative research method. The data and sources of data in this study were speeches or sentences that contained greeting words, being displayed in conversations or utterances between buyers and sellers in the public traditional market of Mojosari. The data collection technique in this study was referring, engaging, noting and surveying techniques, with this technique, the researchers found a reference in finding greeting data. Departing from theose processes, several forms of greeting words were found including the form of greeting words based on (1) gender, (2) age, (3) social status, and (4) kinship. In addition, two functions of greeting words were found, viz. (1) the function of familiarity and (2) the function of respect.
From the results of the analysis and discussion, it was concluded that in the interaction of buying and selling at the Public Traditional Market of Mojosari, various forms of greeting words were found which were determined through several factors such as (1) gender differences, (2) age, (3) social status, ( 4) kinship that leads to the form of familiarity between speakers and the speech partners. The difference was directed to distinguish among greetings for someone who is younger, peer, or older. In addition, it could be seen from the social status and closeness between the speakers and the speech partners. Hence, there will be differences in the use of greetings. The use of greetings can be utilized for people who already know or not with a specific purpose. Each form of the utilized greeting in the interaction of buying and selling at the public traditional market in Mojosari had a function that can reflect the level of closeness between the speaker and the partner. The level of closeness is divided into several parts such as (1) the level of closeness that leads to familiarity, and (2) the level of closeness that leads to respect. Each of these functions, can be adjusted based on the context of use.


The foundation of major hydraulic structures of Gezhouba project,such as the dam,powerhouse etc.,is the red rock bed of lower Cretaceous system. The foundation rock characterizes as low strength, well stratified, bad hydrophysical features and complicated geological condition. Several key technical issues are discussed in this paper, such as the necessity and feasibility of consolidation grouting for foundation rock, feasibility of seepage prevention grouting and judgement criteria for grouting, seepage stability and protection for soft interbedded layer etc. According to the observation data of dam foundation, the foundation consolidation and seepage control measures of the red rock bed and seepage stability and protection effect of soft interbedded layer are analysed and evaluated.

The purpose of this study was to examine the self-perceived quality of life (QOL) using World Health Organization quality of life (WHOQOL-BREF) instrument and associated controlling factors among socio-economically marginalized tribal female tea garden (TG) workers. A cross-sectional mixed-method research design involving both quantitative and qualitative techniques was employed on 378 study samples (18–60 years tribal female TG workers) between February and May 2022 across 10 TGs of Sub-Himalayan north Bengal, India. For the study, both summary statistics (mean, median, mode, standard deviation, and percentage distribution) and inferential statistics (Welch's ANOVA, independent t-test, paired t-test and multivariate regression) were used to understand the dynamics of QOL and respondents narratives were facilitated to investigate the corresponding phenomenal scenario. Results: Findings indicate the QOL of the tribal female workers variably associated with different socioeconomic conditions and subjective well-being. The findings recommend that female tribal TG workers were perceived to have good 'overall quality of life' with a response rate of 33.1%, whereas more than 20% of participants respond that they were poor QOL on 'overall quality of life' and 'general health' items. The findings show lower summary statistics for most items in the environmental domain. Additionally, the study constructs a multivariate model that identifies several factors including socio-economy, neighbourhood, social relation, and others were significantly control the QOL of the study subjects. These outcomes may have important implications for future studies employing WHOQOL-BREF or similar instruments on different communities with distinctive sociocultural characteristics.


With the rapid growth of the Fourth Industrial Revolution (or Industry 4.0), five-axis machining has played an important role nowadays. Due to the expensive cost of five-axis machining, how to solve the collision detection for five-axis machining in real-time is very critical. In this paper, we present a parallel method to detect collision for five-axis machining. Moreover, we apply the bounding volume hierarchy technique with two-level bounding volume represent the surface or solid of the object to reduce triangle meshes inside each axis of the five-axis machine tool, and then matching the operating range limit of the fiveaxis machine tool itself, delete the no colliding triangle mesh. Additionally, we also propose some optimization with loop unrolling and prefetching techniques to improve performance of collision detection. Our approach can reduce the execution time significantly by computing six separating axes in plan and eleven separating axis in non-plan between two triangle meshes based on the characteristic of GPUs (Graphics Processing Units) for program acceleration. Our proposed work consists of kinematic analysis and interpolation for axes to save the numerous collision detection for five-axis machining computations. In this experiment, the result shows that using the proposed approach above can achieve approximately 37.1 times speedup than that of CPU.

Stress in rock masses is an important parameter in the design and construction of underground engineering, such as the design and maintenance of mine roadways and the design of mining working faces. It is also a fundamental force causing the deformation and failure of geotechnical engineering excavation. At present, the abutment-pressure monitoring technology of the surrounding rocks of the coal mine roadway in China is not intelligent and systematic and lacks some high-precision sensing instruments and multi-functional monitoring systems. The mechanical model of the rocks surrounding the borehole was constructed by theoretical analysis of problems in the stress monitoring technology for underground rock masses in coal mines. Additionally, the interaction between the surrounding rocks and the borehole stress meter was analyzed. The borehole stress meters for tubular-structure fiber Bragg grating (TS-FBG) and cystic-structure fiber Bragg grating (CS-FBG) were designed by combining the sensing principle and sensing characteristics of fiber Bragg grating, and the performance of the two kinds of fiber Bragg grating borehole stress meters was compared by laboratory test. The track roadway of the 14,301 tested working faces in the Shaqu Coal Mine was taken as an example, and the stress of the rocks surrounding the 14,301-track roadway was monitored in real time by CS-FBG borehole stress meter during the mining of the working face. The following conclusions are drawn from the field application. The rig-site utilization results revealed obvious stress growth and stress peak zones in the mining-stress change curves of each measuring point on the two sides of the 14,301-track roadway in the process of mining the tested working face. Additionally, there were four stages: rapid rise, uniform growth, rapid rise to the peak, and rapid decline. Maximum stress monitored by the second station was 18.5 MPa, and the influence range of stress was over 140 m. Maximum stress monitored by the first measuring station was 19 MPa, the influence range of stress was about 80 m, and the peak stress position was about 20 m in front of the coal wall. Rig-site utilization proved the design of the CS-FBG borehole stress meter to be reasonable. Performance was stable and reliable, and the successful operation of field monitoring achieved the expected effect.

Many studies have measured biodiversity loss across the coffee intensification gradient; some studies have shown, with contradictory results, the trade-offs between biodiversity loss and coffee production increments. Plot assessments of tree diversity, soil conservation, carbon sequestration and coffee production are lacking. We characterized the structure, productivity, diversity, soil conservation and carbon sequestration of 40 coffee agroforestry systems in two different areas in Northern Nicaragua. Coffee management, environmental conditions and soils properties were also characterized to better understand the trade-offs among services within the plots and their dependence on the local environment. These agroforestry systems were chosen to maximize contrasts in terms of biophysical context, botanical composition and management practices. Results (preliminary) showed significant differences in the vegetation structure that enabled us to identify main clusters: CAFS with dense and diverse overstorey canopy, CAFS with high Musa density and CAFS with low density of overstorey canopy. Changes in vegetation structure reflected differences in farmers' strategies but did not affect the overall coffee yield or the conservation of soils. Coffee yields had strong variations among the plots, and this was mainly related to the amount of fertilizer applied. Neither carbon sequestered, soil conserved nor tree diversity have a significant negative relationship with coffee productivity. However, coffee yields were low comparing with other coffee areas in the region. These results open new perspectives to improve coffee agroforestry systems' structural complexity and their relative ecosystem services without affecting their overall productivity. Further investigations and a more stratified sampling to get a good grasp of the whole range of variability (in highly productive areas with less shade canopy) are needed to fully understand the mechanisms involved in trade-offs.


This article develops the concept of bare nature by examining the interdependent and underlying conditions that make genocidal and ecocidal processes possible. Agamben identifies states of exception as a juridical key to understanding the legitimating logic that facilitate acts of arbitrary exclusion, targeted killing, and the life and death policy decisions that affect large segments of the population. Such regulated, collective precarity constitutes bare life. I argue that bare nature is produced through a parallel process involving ecological "sacrifice zones" that function as states of exception that regulate other-than-human life in service of extreme energy extraction, creating the conditions for ongoing ecological destruction. In the second part of the article, I argue that the local impacts of extreme energy projects like the Canadian Tar Sands contribute to the conditions of bare nature and bare life globally, presenting a ". . . general (transnational) danger threaten[ing] the interests of several states and their inhabitants." In closing, I turn to the ascendant Indigenous politics in Canada to consider what local cultural survival, global ecological adaptation, and nonsovereign governance models involve in the era of climate change. Indigenous-led politics grounded in land-based normative ethics provide a basis for building alternative futures based on establishing and maintaining conditions of holistic interdependence. Such interdependent conditions will be able to emerge in direct proportion to the extent that the conditions of bare life and bare nature are delegitimated, decommodified, and rendered inoperative.


Phytoremediation is an environmental technology in which plants are used for decontamination of organic and inorganic pollutants from soils and water. Acacia seyal Delile was tested for it is ability to degrade crude oil contaminated soil in four concentrations 0.5, 1, 1.5 and 2% (w/w) of crude oil. Plant parameters, degradation percentage, retention time and bacterial count were calculated. Results showed that at the end of the growth period of A. seyal Del no such adverse effect was observed on the shoot length and it is better than that of the control at the 2% concentration by the end of the growth period. This result highlights the ability of A. seyal Del to grow under stress of oil contamination. A. seyal root length has substantially increased at two and four month's interval and no significant difference was observed at these two intervals. A. seyal Del shoot biomass was significantly (p<0.05) negatively affected by crude oil at four month intervals, Root weight of A. seyal Del have decreased steadily. Degradation percentage was found to be in the range between 49-54%. Penadecane is the first compound appear in most cases and the retention time was between 13.7-32.9 min. Number of compounds detected in the rhizosphere  those were 57, 70 and 167 compound after two, four and six month of growth respectively. Viable count of the dominant bacteria showed that there is no significant different between concentrations (P=0.699), also there is no significant difference between intervals (P=0.08) in bacterial number. This study reveals the visibility of using tropical plant Acacia seyal in crude oil degradation.


Understanding the within-city house price distribution, heterogeneity and diffusion is essential for understanding the dynamics of city-level housing markets, but these issues have not been thoroughly investigated. In this paper, we construct a constant-quality spatiotemporal house price index for Beijing's resale housing market between 2011 and 2015, and use this index to examine the within-city house price patterns in this superstar city. The revealed spatial distribution of local house price levels shows plausible structures and evolution. Additionally, local house price changes show significant heterogeneity in terms of both price trends and structural breakpoints. We also find that local house price changes diffuse into neighboring areas. These findings deliver deep insights into within-city housing markets and have important implications for urban planning and housing investment.

OBJECTIVE: To describe the profile of dentists in oral health team of the micro-region of Minas Gerais, Brazil.METHODS: Cross-sectional study with 48 dentists in 16 municipalities, in which data collection was conducted by questionnaire. The variables considered for the study were: training time in years, and monthly real salary (centroid), in compliance with weekly working hours, mode of incorporation into the oral health team, postgraduate course, social participation and ongoing involvement in Family Health. All variables were used to group dentists by Two Step Cluster analysis segmentation, with p <0.05 significance level.RESULTS: They formed three clusters that differed mainly in relation to training time in years (p = 0.007), hours worked (p <0.001), postgraduate course (p <0.001) and social participation (p = 0.031). The first cluster grouped dentists with less training time, receiving an intermediate salary to comply with the stated working hours and lack of post-graduate course, the second grouped dentists with the highest salaries and years of graduation who have post-graduate course and the last was composed of dentists with intermediary training time, the lowest salaries that complied with the working hours, have attended the training course / training in the Family Health Strategy and have no social participation.CONCLUSION: Dentists in the Family Health Strategy differ as regards weekly working hours, postgraduate course and social participation in the city, and the training time can be a critical feature to point out these differences.


Before the 1980s, the bladderwrack (Fucus vesiculosus) formed extensive belts along the SW coast of Finland, but already then it began to decline especially in sheltered bays of the inner archipelago. We studied underwater vegetation by scuba diving in 1993–2007. By 2007, six out of eleven sites had lost their Fucus belts, and sheltered bays had become refuges for the bladderwrack. In 2006–2007, we studied the effects of temperature, transparency, bottom type, shoreline orientation and location on the bladderwrack distributions and depth penetrations at 61 locations across different archipelago zones. Of these, only location indicated a possible effect.


This paper presents a study of the semidirectly closed pseudovariety generated by the aperiodic Brandt semigroup B2, denoted V*(B2). We construct a basis of pseudoidentities for the semidirect powers of the pseudovariety generated by B2 which leads to the main result, which states that V*(B2) is decidable. Independently, using some suggestions given by J. Almeida in his book "Finite Semigroups and Universal Algebra", we constructed an algorithm to solve the membership problem in V* (B2).

The purposes of this study were: 1) to evaluate the new ramp design (exit and entrance ramps combined into one paved surface separated only by a double yellow line) using actual counts of wrong-way movements and comparing them to data collected in previous research, and 2) to make counts of wrong-way movements on about ten other combined ramps to determine if any have problems. A total of 17 ramps were monitored under this study. Three ramps were considered to have serious wrong-way count problems. On all three ramps, countermeasures were taken to reduce the wrong-way movements. Final conclusions are that the combined ramp geometry does reduce the number of wrong-way movements. But alternate forms of signing and marking may be needed.


We employ cosmological hydrodynamical simulations to investigate the effects of AGN feedback on the formation of massive galaxies with present-day stellar masses of $M_{stel} = 8.8 \times 10^{10} - 6.0 \times 10^{11} M_{sun}$. Using smoothed particle hydrodynamics simulations with a pressure-entropy formulation that allows an improved treatment of contact discontinuities and fluid mixing, we run three sets of simulations of 20 halos with different AGN feedback models: (1) no feedback, (2) thermal feedback, and (3) mechanical and radiation feedback. We assume that seed black holes are present at early cosmic epochs at the centre of emerging dark matter halos and trace their mass growth via gas accretion and mergers with other black holes. Both feedback models successfully recover the observed M_BH - sigma relation and black hole-to-stellar mass ratio for simulated central early-type galaxies. The baryonic conversion efficiencies are reduced by a factor of two compared to models without any AGN feedback at all halo masses. However, massive galaxies simulated with thermal AGN feedback show a factor of ~10-100 higher X-ray luminosities than observed. The mechanical/radiation feedback model reproduces the observed correlation between X-ray luminosities and velocity dispersion, e.g. for galaxies with sigma = 200 km/s, the X-ray luminosity is reduced from $10^{42}$ erg/s to $10^{40}$ erg/s. It also efficiently suppresses late time star formation, reducing the specific star formation rate from $10^{-10.5}$ $yr^{-1}$ to $10^{-14}$ $yr^{-1}$ on average and resulting in quiescent galaxies since z=2, whereas the thermal feedback model shows higher late time in-situ star formation rates than observed.


The study was justified on the basis that not sufficient research studies had been done with respect to the role of journalists during perceived or actual terrorist activities targeting world sports events, which was a significantly large research gap that most researchers had not dealt with. The study was important to all the stakeholders who would be interested in knowing the role played by journalists concerning the terrorist attacks during world sports events. The data from telephone interview of journalists were taken through a discourse analysis. The results of the discourse analysis showed that the journalists competed in being the first to give breaking news, a notion that might have explained the reason why the journalists did not consider verifying the authenticity of whether the attacks amounted to terrorism. Moreover, results of the study indicated that the misinformation about the Boston Marathon attacks could have been due to the influence of interest groups, who might have been interested in destroying the reputation of the government with respect to security. To achieve this, the results showed that a respondent believed that some journalists might have been influenced to provide inaccurate information about the Boston attacks.


The positive prekernel, a solution of cooperative transferable utility games, is introduced. We show that this solution inherits many properties of the prekernel and of the core, which are both sub-solutions. It coincides with its individually rational variant, the positive kernel, when applied to any zero-monotonic game. The positive (pre)kernel is a sub-solution of the reactive (pre)bargaining set. We prove that the positive prekernel on the set of games with players belonging to a universe of at least three possible members can be axiomatized by non-emptiness, anonymity, reasonableness, the weak reduced game property, the converse reduced game property, and a weak version of unanimity for two-person games.


Background: The cervix of uterus is prone to develop neoplastic and nonneoplastic gynecologic lesions. The histological lesions that are found in the uterine cervix cannot be always established only with conventional cytology. Thus, it is very important that any cytological abnormality be subsequently correlated with biopsy for certification of a cervical lesion.

Objective: To evaluate histomorphologic features of all types of nonneoplastic lesions of the uterine cervix.

Materials and Methods: The retrospective study consists of total 630 cases that were submitted for routine histopathologic investigations. All specimens were fixed, dehydrated, embedded, and subsequently stained with hematoxylin and eosin. Special stains, such as mucicarmine and PAS - Periodic acid–Schiif, were employed wherever necessary.

Result: Among the 630 cervical specimens, inflammatory lesions formed the major part (71.42%) followed by cervical malignancies (12.69%). Benign cervical lesions and cervical intraepithelial neoplasia constituted 6.98% and 4.44%, respectively. The noninflammatory cervical glandular lesions constituted 2.85%.

Conclusion: Inflammatory lesions were the most common cervical lesions followed by malignancies. Among inflammatory lesions, chronic nonspecific cervicitis was commonly found followed by papillary endocervicitis seen in sexually active females with pelvic inflammatory disease, dysfunctional uterine bleeding, uterine prolapsed, and so on. The most common cervical malignancy was squamous-cell carcinoma, moderately differentiated being the most common type.

Based on the experimental data of KY3F10∶Tm3+ reported by Diaf, Kushida′s spectral overlap model (SOM) of energy transfer between J-multiplets was studied. Firstly, with the help of the Inokuti-Hirayama and Yokota-Tanimoto models, the luminescence decay curve of 3H4 of Tm3+ ion was fitted, and the fitted values of corresponding interaction parameters CDA of energy transfer and CDD of energy migration were obtained. Secondly, by compared with Kushida′s SOM in which the relevant Judd-Ofelt approximative transition rates are known, the average overlap integrals of SDD and SDA were obtained. For SDD, how to treat the contribution of the electronic-dipole (ED) crystal field transition forbidden by C4v site symmetry in the calculation of SDD was discussed. For SDA we suggested that, by including the contribution of the phonon sidebands in the analysis of oscillator strength of transition, Kushida′s SOM of ED-ED resonant energy transfer rate can be extended to non-resonant phonon-assisted D-A energy transfer. The strengths and widths of phonon sidebands in this example were discussed, and the results were reasonably good.


This research has studied the effect of a new biological treatment technology on the activity of bile salt hydrolase ( BSH) and viable count. The BSH was produced by Lactobacillus casei KL1 strain which separated from Tibetan Kefir. The new biological treatment technology is a method which leads to biomutation by using the effect of human biological energy on cells and genetic material. It is a new mutagenesis technology,different from physical and chemical mutagenesis. At the first,the ab-sorbance of amino acid existing in BSH ( at A570nm) was detected by ninhydrin reaction. Then the effect of the new biological treatment technology on the activity of BSH was determined. Secondly,the optical density ( OD 600nm) of the broth was studied by UV spectrometer. Finally the effect of the new method on KL1 strain viable count was analyzed according to OD 600nm. The results showed that after handled by the new method,the activity of BSH was significant increased ( p 0. 05) ,as well as the viable count ( p 0. 01) . It indicated that this new method can evidently increase the activity of BSH and viable count of KL1 strain,and the viable count and the activity BSH were in positive corrdation.


Business Process Analysis (BPA) is a strategic activity, necessary for enterprises to model their business operations. It is a central activity in information system development, but also for business process design and reengineering. Despite several decades of research, the effectiveness of available methods is still questionable. The majority of methodologies adopted by enterprises are rather qualitative and lack a formal basis, often yielding inadequate specifications. On the other hand, there are methodologies with a solid theoretical background, but they appear too cumbersome for the majority of enterprises. This paper proposes a knowledge framework, referred to as BPA Canvas, conceived to be easily mastered by business people and, at the same time, based on a sound formal theory. The methodology starts with the construction of natural language knowledge artifacts and, then, progressively guides the user toward more rigorous structures. The formal approach of the methodology allows us to prove the correctness of the resulting knowledge base while maintaining the centrality of business people in the whole knowledge construction process.


In this paper,the comparable experimental investigation on the atomization effect before and after installation of injection ejector in the spiral atomizer was carried out.The analysis and comparison indicate that the atomization effect can be improved greatly after using injection ejector in the spiral atomizer.In addition,in two-phase flow which is consist air or steam and water,internal energy for bubble plays an important role in water flow atomized are pointed out in theory.Finally,it points out that using injection ejector in the spiral atomizer is feasible.Besides,the technology has good economic and social benefits after applying in industry.


Comparisons of age cohorts of adults2 have shown mainly an agerelated decrease of the frequency of the first formant (F1), and this has been hypothesized to be related to changes in the length and/or volume of the vocal tract (Linville and Fisher 1985; Xue and Hao 2003). Longitudinal studies (Harrington 2006; Harrington, Palethorpe and Watson 2007) confirmed that F1 typically decreased with increasing age. In Reubold, Harrington and Kleber (2010), the mean fundamental frequency (f0) and mean F1 were found to covary over a 50year period for the British Queen Elizabeth II (linear decrease of both parameters) and for the broadcaster Alistair Cooke (a decrease of both parameters followed by a late, very pronounced increase). Our explanation was that f0 is likely to change for physiological reasons (Linville 2001; Gugatschka et al. 2010) but that F1 may track f0 for auditory reasons. This is because the distance between f0 and F1 has been shown to be a cue to vowel height (Traunmüller 1981), at least when f0 and F1 are close enough in frequency to be perceptually integrated (Chistovich and Lublinskaya 1979). That is, the speakers may be recalibrating their F1 in relation to f0 in order to maintain a perceptually constant vowel height over the lifespan. A subsequent analysis in Reubold and Harrington (2015) showed for Cooke that this relationship between f0 and F1 over the lifespan occurs predominantly in phonetically high vowels (in which f0 and F1 are close together in frequency), whereas the relationship was less clear in mid vowels. In phonetically low vowels by contrast, there were F1 changes that were not related to longitudinal shifts in f0 but mainly characterized by increasing centralization at an older age (see Rastatter and Jacques 1990). The Influence of Age on Estimating Sound Change Acoustically From Longitudinal Data


With the increasing use of solar photovoltaics, wind-induced loads on rooftop solar arrays have become a problem. A series of wind tunnel experiments have been performed to evaluate wind loads on solar panels on flat roofs, mainly focusing on their area-averaged characteristics such as mean and negative peak force coefficients, and peak factors. Solar array models were fabricated with pressure taps installed as densely as possible to identify the area-averaged characteristics. Design parameters of solar arrays including panel position, tilt angle and distance between arrays have been considered. Although values for unfavorable mean and peak differ for different tilt angles, the variation tendencies and peak factors are similar. The results were also compared to Japanese Standard (JIS C 8955) which correctly estimates negative mean module force coefficients but not peak values.


Delirium, an acute brain dysfunction, is a common and serious complication in burn patients. The occurrence of delirium increases the difficulty of patient treatment, is associated with various adverse outcomes, and increases the burden on the patient's family. Many scholars have studied the factors that cause delirium, but the causes, pathogenesis, and treatment of delirium in burn patients have not been fully revealed. There is no effective pharmacological treatment for delirium, but active preventive measures can effectively reduce the incidence of delirium in burn patients. Therefore, it is necessary to study the relevant factors affecting the occurrence of delirium in burn patients. This study was conducted on December 20, 2021 by searching the PubMed database for a narrative review of published studies. The search strategy included keywords related to "burns," "delirium," and "risk factors." We reviewed the characteristics of delirium occurrence in burn patients and various delirium assessment tools, and summarized the risk factors for the development of delirium in burn patients in terms of personal, clinical, and environmental factors, and we found that although many risk factors act on the development of delirium in burn patients, some of them, such as clinical and environmental factors, are modifiable, suggesting that we can estimate the exposure of burn patients to risk factors by assessing their likelihood of delirium occurring and to make targeted interventions that provide a theoretical basis for the prevention and treatment of burn delirium.


Review spam is an opinion written to promote or demote a product or brand on websites and other internet services by some users. Since it is not easy for humans to recognize these types of opinions, a model can be provided to detect them. In recent years, much research has been done to detect these types of reviews, and with the expansion of deep neural networks and the efficiency of these networks in various issues, in recent years, multiple types of deep neural networks have been used to identify spam reviews. This paper reviews the proposed deep learning methods for the problem of review spam detection. Challenges, evaluation criteria, and datasets in this area are also examined.


trations in patients with diabetes (Zehetner et al. 2013). Yet, it remains unclear whether HbA1c correlates also with the concentrations of vasoactive proteins in the ocular tissues. Here, we report data of 39 diabetic eyes that were vitrectomized either due to persisting vitreous haemorrhage (VH), diabetic macular oedema (DME) with vitreomacular traction or due to proliferative diabetic retinopathy (PDR) with or without tractional retinal detachment (TRD). Intravitreal total protein concentrations were measured using a bicinchoninic acid protein assay kit (Pierce, Thermo Scientific, Rockford, IL, USA). Ang-2 and VEGF were measured by enzymelinked immunoassay kits (R&D Systems, Minneapolis, MN, USA). Using linear regression models, we demonstrate an association between the HbA1c and intravitreal levels of Ang2. We adjusted univariate model with sex and age and then added the following variables one at a time into the model: type of diabetes, duration of diabetes, body mass index, VH, DME, PDR, fibrosis formation and TRD. We found positive association between HbA1c and Ang-2 (p = 0.001), but not with VEGF (p = 0.327) in the patients with diabetes undergoing primary vitrectomy due to DR complications. Intravitreal Ang-2 levels were independent of duration of diabetes (p = 0.686) and the corresponding Ang-2 concentrations in the plasma (p = 0.680). The association between HbA1c and intravitreal Ang-2 levels remained significant in multivariate linear regression analysis including the confounding factors. Only TRD associated significantly with intravitreal Ang-2, but even after adjusting for it, the association with HbA1c remained significant (p = 0.015, Fig. 1). High intravitreal Ang-2 levels in patients vitrectomized due to TRD could be explained by the response to the tissue trauma, hypoxia and inflammation. Overall, these results reveal a relationship between poor glycemic control and high intravitreal Ang-2 levels, emphasizing that Ang-2 may play a role in the DR progression in patients with diabetes with high HbA1c. Conflict of interest: no conflicting relationship exists for any author. References


Abstract : The effects of monomethylhydrazine on several commonly used cryopanel materials were investigated. The test conditions approximated those expected during rocket engine tests in a space simulation chamber. Monomethylhydrazine gas pressure was 4 torr at room temperature. Test specimen temperatures were varied between 77 and about 300K. All specimens were tested simultaneously for a total exposure time of 532 hr. Phosphorus deoxidized copper, type 304L stainless steel, and series 1100 aluminum were tested. Some specimens were brazed or welded and some were coated with a black epoxy paint. Several welded and brazed specimens were tested with an imposed bending stress. No microstructural damage occurred to any of the metals. The copper, however, tarnished noticeably, and the cryopanel paint separated from the coated specimens.


It's worth discussing whether the local farmers have improved their understanding of ecological value of forests or joined the construction of non-commercial forests actively through the related forest policies. This paper used the Logistic modeling to analyze farmer households' willingness to join the construction of non-commercial forests based on a survey of farmer households in 10 villages of Changxing. Accord-ing to the findings,the paper gave some suggestions on improving farmer households' willingness to join the construction of non-commercial forests,such as expanding the source of non-agriculture income of farmers,improving the non-commercial forest compensation standard,providing trainings for farmers,improving their awareness of ecological environment.

This study investigated the use of antioxidant during slurry propylene polymerization using the Ziegler–Natta catalyst. Antioxidant masking using tri ethyl aluminum is the key to reducing the destructive effect of antioxidants containing OH phenolic groups on Ziegler–Natta catalyst performance. Polymer characteristics such as catalyst activity, and oxidative induction time of the products in the presence of different amounts of antioxidant were evaluated. The results shown that the activity of catalyst in presence of masked antioxidant has not decreased. The oxidative induction time (OIT) results indicated that masked antioxidant during PP polymerization did not affect OIT of the products.


This paper is to present a simulation model for the performance evaluation of Adaptive Rate Control for VoIP on Wireless Ad Hoc Networks. We use simulation to capture the characteristics of wireless channel and implement the speech coding standard AMR-WB. The basic idea of our rate control scheme is to adapt the voice coding bit rate to the available network bandwidth in order to maximize the quality of voice. We designed the ad hoc and adaptive control model to simulate our scheme.


This paper assesses the introduction and application of design solutions at the early stages of snowblower design. Analytical expressions were obtained for the volumes of snow mass cut by the horizontal and vertical cutters of the rotary snowplow feeder. The time of transporting the cut snow mass was estimated. The influence of the design and technological parameters on the size of the cut snow mass and the time of its transportation is shown. The results show the range of values in which the length of the cutting path of the snow mass for a horizontal cutter is less than the length of the cutting path for a vertical cutter.


Innovation is dependent on a continuous flow of ideas that bring opportunities for new products and technologies. This study explores ideation as an independent process, related but not restricted to the innovation process. To this end, a multiple case research method was employed in 15 Brazilian companies. As a result, a framework comprised of the core elements of ideation processes is proposed, showing that other characteristics, apart from the idea generation and selection, need to be addressed to achieve effective results, such as innovation environment, strategic orientation, and idea sources.


. We describe the morphology and ultrastructure of the free-swimming larvae of the sponge Crambe crambe, one of the most abundant encrusting sponges on shallow rocky bottoms of the western Mediterranean. Larvae of C. crambe are released in July and August. The larva is uniformly flagellated except at the posterior zone. Flagellated cells are extraordinarily slender, elongate, and sinuous and form a pseudo-stratified layer. Their distal zone contains abundant mitochondria, some small vesicles, a Golgi complex, and the basal apparatus of the flagellum. Abundant lipid droplets are present throughout the cell. The nucleus is most often in a basal position. The flagellum projects from the bottom of an asymmetrical socket formed by cytoplasmic expansions. The basal body extends in a conical tuft and a laminar rootlet in close association with the Golgi system. The cells at the posterior pole are flat and polygonal on the surface, with long overlapping pseudopodia in the typical shape of a pinacoderm. Sparse collagen is present throughout the whole larva including the flagellated layer. Archeocytes and sclerocytes are abundant in the posterior region. Typical collencytes and spherulous cells seem to be absent. Intracellular and extracellular rod-like bacteria with conspicuous fimbria occur exclusively in the posterior region of the larva. The asymmetrical cytoplasmic prolongations, which surround the flagellum, and the basal apparatus of the flagellum are suggested as the sites of stimulus reception and triggering of locomotor responses, respectively. This ultrastructural study of the larva of C. crambe has shown features directly linked to its behavior and ecology.

Abstract The extension of the quasi-steady radially symmetric theory of liquid-droplet vaporization and homogeneous combustion to solid fuels and additives requires several basic modifications. One relatively simple extension, undertaken here, permits the gasification process al the two-phase interface to be modelled not by adiabatic sublimation, but by finite-rate heterogeneous chemical reaction. Such an extension by itself allows the burning of solid spheres of carbon to be adequately described. In particular, for carbon spheres, surface reactions involving production of carbon monoxide (by consumption of oxygen or by reduction of carbon dioxide) and of carbon dioxide (by consumption of oxygen) may be coupled with a bipropellant homogeneous reaction between carbon monoxide and oxygen. More general results for the net mass transfer rate (the Sherwood number) with nonequilibrium reversible heterogeneous reactions than previously obtained are presented. Further, closed-form results are derived for special ...

Modern parallel architectures are emerging with sophisticated hardware consisting of hierarchically placed parallel processors and memories. The properties of memories in a system vary wildly, not only quantitatively (size, latency, bandwidth, number of banks) but also qualitatively (scratchpad, cache). Along with the emergence of such architectures comes the need for effectively utilizing the parallel processors and properly managing data movement across memories to improve memory bandwidth and hide data transfer latency. In this paper, we describe some of the high-level optimizations that are targeted at the improvement of memory performance in the R-Stream compiler, a high-level source-to-source automatic parallelizing compiler. We direct our focus in this paper on optimizing communications (data transfers) by improving memory reuse at various levels of an explicit memory hierarchy. This general concept is well-suited to the hardware properties of GPGPUs, which is the architecture that we concentrate on for this paper. We apply our techniques and obtain performance improvement on various stencil kernels including an important iterative stencil kernel in seismic processing applications where the performance is comparable to that of the state-of-the-art implementation of the kernel by a CUDA expert.


The theory of optimal control is used to find the best trajectories for the capture maneuver of an interplanetary probe, which employs electric propulsion. The thrust magnitude and direction are optimized to exploit the spacecraft continuous steering capabilities and maximize the spacecraft final mass. Strategies, which involve propelled and coast arcs, are analyzed. The influence on the optimal trajectories of some parameters, such as the thrust, the specific impulse, and the initial velocity, is also discussed


Direct-driven electro-hydraulic systems have a wide range of applications owing to their advantages of energy-savings and relatively high control flexibilities in comparison with classic variable displacement pump-controlled hydraulic systems. However, the control accuracy is limited by the inherent nonlinear hydraulic dynamics. Additionally, the pump flow rate may become nonlinear at low pump speeds, causing large pressure-related flow deviations; thereby, limiting the improvement of motion control accuracy. Unfortunately, the pump flow nonlinearity has been ignored or oversimplified without effective modeling in most studies so far. To improve the control accuracy of direct-drive hydraulic systems, a high-precision control strategy must be designed to deal with the nonlinear characteristics and resolve the issue of nonlinear pump flow at low speeds. This article proposes an adaptive robust motion control strategy for a direct-driven electro-hydraulic system with adaptive pump flow rate model compensation. A backstepping integrated direct/indirect adaptive robust controller is designed to deal with the dynamic nonlinearities and uncertainties, which guarantees the stability of the entire hydraulic system. Furthermore, a parameterized polynomial fitting modeling strategy is proposed to accurately describe the nonlinear characteristics of the pump flow rate. Therefore, the uncertain parameters are adjusted in real-time, achieving satisfactory parameter estimations and model compensation for asymptotic motion tracking. Theoretical proof and comparative experiments demonstrate the advantages of the proposed control strategy with adaptive polynomial fitting model compensation for high-precision motion control.


With the detection of giant extrasolar planets and the quest for life on Mars, there is heightened interset in finding earth-class planets, those that are less than ten earth masses and might be life supporting. A space-based photometer has the ability to detect the periodic transits of earth-class planets for a wide variety of spectral types of stars. From the data and known type of host star, the orbital semi-major axis, size and characteristic temperature of each planet can be calculated. The frequency of planet formation with respect to spectral type and occurrence for both singular and multiple-stellar systems can be determined. A description is presented of a one-meter aperture photometer with a twelve-degree field of view and a focal plane of 21 CCDs. The photometer woudl continuously and simultaneously monitor 160,000 stars of visual magnitude <EQ 14. Its one-sigma system sensitivity for a transit of a 12th magnitude solar-like star by a planet of one-earth radius would be one part in 50,000. It is anticipated that about 480 earth-class planets would be detected along with 140 giant planets in transit and 1400 giant planets by reflected light. Densities could be derived for about seven case where the planet is seen in transit and radial velocities are measurable.


I have gathered from the Parsi theatre and the early Indian cinema. My context is the commercial entertainment industry arising from new entrepreneurial modes, uses of urban space, structures of leisure time, and the consumable pleasures of music, dance, and drama, all in complex interaction with technologies and cultural forms introduced during colonial rule. The period covered is from 1853, when Vishnudas Bhave and his troupe performed 'Raja Gopichand' in Hindustani before a public audience in Bombay and sparked an upsurge of theatre activity to 1931 when the first sound feature film, Alam Ara, was released, also in Bombay, following which Parsi theatre began to wane. While the geographical focus is on western and northern India, the extensive tours of the Bombay-based troupes to Madras and Ceylon, Calcutta and Rangoon, Peshawar and Sindh, and points in between. and the founding of innumerable local and regional groups styled after the Bombay companies, extend the implications of the thesis to a wider territory.


Functional abilities in children with autism spectrum disorder (ASD) are highly heterogenous, and impairments can overlap with non‐ASD neurodevelopmental disorders. We compared the profiles of children assessed for ASD with and without an ASD diagnosis using a retrospective cohort study of 101,739 children born in British Columbia (2000–2008). The children were grouped into the following five comparison groups: (1) ASD− (n = 1131), (2) ASD+ (n = 1583), (3) Ministry of Education designated ASD+ (n = 654), (4) special need other than ASD (n = 11,663), and (5) typically developing (n = 86,708). Five developmental domains were assessed using the Early Development Instrument. ANCOVA was used to control for covariates, Tukey's HSD test for multiple comparisons, and Cohen's d for effect size. The ASD− group had slightly higher scores than the ASD+ group with small to medium effect sizes in all domains (d = 0.20–0.48). The ASD− group had slightly higher scores than the Ministry of Education ASD+ group in only three domains with small effect sizes (d = 0.21–0.25). The ASD− group had lower scores in all domains compared to the typically developing group with large effect sizes in all domains (d = 1.12–1.77). The ASD− group received less education funding at school entry than both ASD+ groups. Overall, only small to medium differences in development were detected between the ASD− and ASD+ groups. While these children differ diagnostically, they share similar functional profiles and have substantially more difficulties than typically developing children. Therefore, differences in levels of support at school entry raise critical questions of equity.

Abstract : A study is made of the aerodynamics of a turbulent diffusion flame jet developing in a homogeneous wake flow. A second extremum (minimum) is found in the dynamic head profiles. The nature of the effect of the wake-flow velocity on the structure of the flame is clarified. The experimental results can be explained on the basis of the general theory of free turbulence in an isobaric flow. (Author)


In response to our TH!NK program, designed to engage students in critical and creative thinking across the campus, and the need to provide more students with authentic research experiences, we have designed and integrated several course‐based research labs into our curriculum. These courses have allowed undergraduates to engage in meaningful research beyond the classroom without taxing the space, time, and resources of the current research faculty. Our newest cell biology lab, using cell culture, Western blots, and immunofluorescent chemistry allows students to learn advanced lab techniques and data analysis typically reserved for faculty research labs. Course‐based research allows student to receive credit toward their degree and allows them the opportunity to design and implement original experiments within a framework for potential publication. Since the development of these courses, students who have taken one or more of these labs have scored higher on post assessments related to applying scientific methods and scientific communication – a key departmental learning outcome ‐ than students who did not take these labs. (92% vs 74% competency on post‐assessments).


This essay deals with the insertion of Bioethics in undergraduate Nursing courses. First, we present some considerations about the origin of Bioethics in Brazil and abroad. Next, we discuss how Bioethics is presented to health professionals, according to literature. A survey of nursing publications found few studies, a fact that motivated us to write this essay. There is a need to look into this matter, realizing studies to identify how undergraduate Nursing courses are preparing their students to deal with bioethical dilemmas in practice.


Differential effects of simazine (2-chloro-4,6-bis(ethylamino)-s-triazine) on the physiology of two Populus clones were investigated in a greenhouse study. Additions of 5 mg/pot simazine to young plants had no deleterious morphological or physiological effects on clone NC 5328 (P. x euramericana cv. I 45/51; Section Aigeiros), but reduced the rate of CO2 fixation, increased CO2 compensation concentrations and lowered the specific leaf weight of clone NE 388 (P. maximowiczu x P. trichocarpa cv. Kingston; section Tacamahaca). Abaxial leaf conductance to water vapor was not affected in NE 388. Deleterious effects of simazine on NE 388 were detected ca 48 h after exposure of plants to simazine and generally became more pronounced thereafter. Visual symptoms of injury were evident at ca 2 weeks after simazine application.

Toxic responses to simazine in clone NE 388 varied in different portions of the crown. Inhibition of photosynthesis and increased CO2 compensation concentrations were more pronounced in the region of recently matured leaves, but were somewhat less in the region of expanding leaves. Older mature leaves in the lower crown region showed no visual symptoms of injury and the rate of photosynthesis and CO2 compensation concentrations were largely unaffected.


A structuralist-semiotic approach promotes understanding of the meanings of ritualistic bodily inscriptions. Two conspicuous examples of bodily inscriptions are the marks on Jesus's body as understood in medieval piety, and the mangled and flayed bodies of Aztec ceremonial practice. Throughout, a bodily inscription is any alteration, such as piercings or circumcisions or marks of punishment, that has one or more meanings. Foucault's analysis of power brings out points of both similarity and difference between the Christian and Aztec examples. Thereby one gains a deeper grasp of these bodily inscriptions. One also sees that these inscriptions, far from being solely aesthetic or mutilative, function as strategies within a system of power relations. Anyone who sees the comparison of Christian and Aztec practices to be a strained or unpromising enterprise should bear in mind Richard Trexler's work on New World sexuality and practices as perceived and criticized by the Spanish, and Eva Hunt's enduring contribution to the understanding of a Mesoamerican deity and its cosmological and cultural dimensions.


1 Objectives In present work we study Ge islands growth in Si substrate. Two types of samples are under study: the first one, Ge dots are grown by Stranski-Krastanov mechanism, that result the appearance the Ge islands on the top a quantum well (wetting layer - WL), this method permit the appearance of islands highly ordered with lateral density up to 1x10 11 cm 2 ; the second type of dots are growth in an ultra thin layer of SiO2, with this new method one can obtain Ge islands with higher density and small size. These Ge/Si dots are useful for electronic devices, integrated circuits, lasers and for several applications in microelectronic devices. Results In this year's work we focussed our studies in the structural characterization through X-ray diffraction, and Rutherford Backscattering Spectroscopy (RBS), of Si/Ge samples with Ge islands. Some work was done on optical characterization with photoluminescence.


It has been shown previously that the quality of control achievable for a certain system (its dynamic resilience) is limited by the nonminimum phase characteristics of the plant, constraints on the manipulated variables and model uncertainty. Model uncertainty requires the controller to be detuned and performance to be sacrificed. The goal of this paper is to quantify this well known qualitative statement. A general discussion of the model uncertainty problem is followed by the derivation of simple bounds on the nominal performance imposed by the robust stability condition for some uncertainty descriptions. These bounds are relatively easy to evaluate and should be effective tools for screening alternate designs in terms of their resilience characteristics. It is shown that the use of the minimized condition number as a sensitivity measure implicity assumes that the relative errors of the transfer matrix elements are independent and have similar magnitude bounds.


With the proliferation of flip chip packaging and multiple metal layer technology in advanced semiconductor integrated circuits (IC's), traditional front-side probing and failure analysis tools are no longer viable. Full transistor level access from the substrate side (i.e., backside) of the chip is now required to fully realize such investigative work. Silicon is transmissive in the near-IR above its bandgap (≅ 1,000nm to 1,100nm). As a result, transistor level access can be achieved by optical means. To enable such optical access, it is necessary to first remove all heat dissipating devices such as finned heat sinks and integrated heat spreaders placed in contact with the silicon substrate. For most applications, the silicon is then mechanically thinned down to approximately 100μm, and a microscope objective is used to "probe" the chip optically for diagnostics and failure analysis. During such diagnostics and failure analysis, the device under test (DUT) is electrically exercised typically "at speed", which translates into high power dissipation levels. A thermal management system that can be physically and optomechanically integrated with state-of-the-art diagnostics and failure analysis systems, and can dissipate significant power levels is required to maintain the DUT's temperature equilibrium and avoid thermal runaway, that could irreversibly damage the DUT. One possible and efficient solution is provided by spraying a dielectric coolant directly onto the chip. In the present study, a test chip was used in conjunction with an exact model of a novel microscope objective that is in full contact with the device. The test chip was powered in increments from 0 to 82W/cm2 , and the device level temperature was measured by several temperature sensors embedded in the chip. A spray head was designed to deliver conditioned coolant to the test chip's surface, while simultaneously accommodating the obstruction of the microscope objective and allowing full optical access to the entire chip surface. Thermal performance results for the cooling system are provided for uniform heat flux levels of 30, 52, and 82W/cm2 , with the optical probe located in the worst-case center of the test chip. For all heat fluxes studied, the maximum device level temperature did not exceed 60°C, the across-chip temperature differential was approximately 31°C, and surface temperature fluctuations were seen to have a standard deviation of less than ±1°C. The results are discussed in-depth, and are put in perspective of industry needs.Copyright © 2003 by ASME


Summary Trans-ilial brace fixation was used as the primary repair of two sacral fractures and in conjunction with a trans-sacral pin for the repair of a bilateral sacro-iliac luxation and a sacral fracture with contralateral sacroiliac luxation. Trans-ilial brace fixation was also used as a secondary fixation for two unilateral sacro-iliac luxations and a bilateral sacro-iliac luxation. Follow-up radiographic parameters were compared to post-operative radiographic parameters to assess the stability of the fixation and the progression of healing. There was not any morbidity associated with the trans-ilial brace technique and all of the cases healed uneventfully. Indications for the use of the trans-ilial brace include sacro-iliac injuries where an additional means of stability may be indicated, comminuted sacral fractures in which the landmarks for lag screw fixation are obscured and bilateral sacro-iliac injuries with the concurrent use of a trans-sacral pin.

In a world where social, environmental and health crises are becoming more common we need to find strategies to respond to sudden changes without compromising important principles such as transparency, integrity and accountability. If every day presents a new crisis, do we end up in a perpetual 'fire-fighting' and 'emergency' mode or do we adopt an adaptable procurement methodology that helps us swiftly address any challenge? This paper advocates for a dynamic whole cycle procurement model as an effective way to adjust to ever-changing circumstances and remain relevant for the future. The model adopts a holistic approach to public procurement, starting from needs identification and design of successful strategies, building on effective procurement processes and leading to good contracts and ability to review and reflect. The dynamic interaction between the different stages, the suggested key governance checkpoints, as well as the adoption of the 'right process' and multidisciplinary perspective are the core themes of the paper. The article synthesises procurement practice and methodologies in a pragmatic, yet comprehensive and engaging way and encourages interdisciplinary dialogue. An important feature of the proposed model is that it is powered by constant flow of feedback and is subject to adjustments when circumstances change, within permissible limits. In addition, it suggesta a distinction between formal checkpoints and informal self-governance at various stages of the cycle. Most importantly, the paper aspires to showcase procurement as an inspiring and dynamic profession rather than a bureaucratic administrative function and offer some practical tips and reflections on how to master the 'art' of procurement.


During surveys for Phytophthora ramorum in garden centres in Majorca, Spain, 31 isolates of Phytophthora were recovered from potted strawberry trees (Arbutus unedo) showing leaf and twig blights. Many isolates of Phytophthora syringae and Phytophthora citrophthora as well as single isolates of P. ramorum, Phytophthora tropicalis and Phytophthora nicotianae were identified on morphological features and on the sequences of the internal transcribed spacer regions from ribosomal DNA genes. Phytophthora syringae was collected most frequently in late autumn and winter, whereas P. citrophthora was dominant during late summer and autumn. In vitro pathogenicity of P. syringae and P. citrophthora was compared with that of P. ramorum by inoculating intact detached leaves of A. unedo with zoospores and twigs with mycelial plugs. In addition, in vitro sporangial production was examined on inoculated excised leaves and on agar plugs at 12, 15 and 20°C. Phytophthora citrophthora produced the largest lesions both on leaves and on twigs at all temperatures. Phytophthora ramorum formed lesions comparable in size to those of P. syringae, but it significantly produced more sporangia on excised leaves and agar plugs. In a log inoculation assay, P. syringae caused large lesions in the inner bark, whereas those of P. ramorum were moderate. Strawberry tree blight has not yet been observed in natural ecosystems in the western Mediterranean areas. Possible biological and environmental limitations hindering disease spread in the wild are discussed.


In order to obtain a better understanding of combustion and ignition properties of ammonium nitrate (AN) and activated carbon (AC) mixtures, friction test, thermal analysis, and 200-mL closed vessel combustion test were carried out and the influence of the mixing ratio on the combustion and ignition properties of various compositions of AN/AC mixtures was investigated. As a result of the BAM friction sensitivity test, all mixtures showed negative results. From differential scanning calorimetry (DSC) test results, each AN mixed with more than 4 wt% of AC mixtures showed violent exotherm after the melting of AN and some of the mixtures exploded in a SUS crucible. The largest heat of reaction was observed at a higher concentration than the stoichiometric composition. The results of 200-mL closed vessel test showed that the powdered AN and the phase stabilized AN (PSAN) mixed with AC showed a fast reaction and a high pressure due to the large amount of gas release and the maximum pressure, and the maximum rate of pressure rise showed the maximum values at a higher concentration than the stoichiometric composition.


The monitoring of equipment and operating conditions of a complex installation is an important task for an accelerator control system, especially for a machine with high intensity circulating beams like the ISR. It is essential that the control system provides the relevant correct alarms and warnings whilst at the same time not flooding the operators with irrelevant information. At the ISR a system has been introduced which displays fault conditions as text messages on a colour display. In conjunction with these messages it is possible for the operator to obtain supplementary information concerning the fault or actions that should be taken. The operator also has facilities to cancel fault messages, to ignore them and to supervise the monitoring programs. The texts for the messages are kept on a database in order to facilitate their modification. All fault messages are printed and kept on a file for later extraction by an interrogation program. This allows for the easy analysis of fault situations or for the production of statistics.


The sustainable humanitarian supply chain (SHSC) has been the subject of research and debate over recent years. The aim of the paper is to provide an SHSC definition, propose an SHSC structure and validate it empirically. A unique contribution of the present study is an attempt to delineate humanitarian supply chain (HSC) management from commercial supply chain management and further discuss the HSC from the point of view of sustainability. We identify three important characteristics of a HSC network: agility, adaptability and alignment, and further explore possible linkages using extant literature and interpretive structural modelling (ISM). We further test the constructs using confirmatory factor analysis. In this way we attempt to answer long-pending calls from past researchers to contribute to the existing theories of HSC and identify further research directions based on the limitations of the present study.


Psychologists and organizational behavior experts have long recognized that there are two types of stress, one negative and the other positive. One leading researcher, Dr. Hans Selye, labeled them distress (negative) and eustress (positive).' We have already discussed the negative aspects of stress. Now, let's look at some of the more positive ways in which you and your staff can feel stress, and how it can even be used as a management tool.

Internet access can improve people's life quality by helping them to reduce and overcome the poverty and educational gaps. However, most rural communities in the world, specially in underdeveloped countries, do not have access to the Internet. Delay/Disruption Tolerant Networking (DTN) is a recent low-cost technology now being used to provide connectivity to rural towns were some transportation means periodically arrive. DTNs can be implemented to connect communities to Internet, since this technology takes advantage of the existing people's transportation infrastructure using it to move packets and messages to and from Internet. This paper proposes a DTN mathematical optimization model that maximizes the availability probabilities of the paths from sources to destinations. We also present an opportunistic forwarding algorithm that takes into account the availability probability of a node's neighbors to decide if a node should forward a message or store the message until a node with a higher availability probability contacts it. This algorithm was tested in five different scenarios and in all of them it found a path to the destination.


Abstract Mechanical trading rules seem to have more potential than previous tests found. Fama and Blume (1966), looking at the Dow 30 of the late 1950s, found no profits for the best (½-percent) rule after adjusting for transactions costs. Fifteen of these stocks looked profitable in their sample, however; for the same rule, the surviving fourteen show statistically significant profits for 1970–1982 for transactions costs obtainable by floor traders. The test used here assumes constant risk premia, or more generally, that risk premia are on average approximately the same on days "in" as for the total period.


Nowadays, with the development of technology people's lives have adapted to new situation and  individuals have started to carry all the communication, socialization, banking, navigating and many  other things they need through applications on their smart phones. The main purpose of this study is  to examine the features of the mobile phone applications and the effects of these features on the brand  value through users' satisfaction. In this study, the utilitarian benefits, consist of application quality  and application utility, hedonic benefits, consist of enjoyment and aesthetics, privacy risk, technicality,  and perceived price were determined as the factors assume to have an impact on satisfaction directly,  and brand equity correspondingly. All of the concepts used in this study were firstly analyzed with  Exploratory Factor Analysis (EFA) and their reliability were measured. Afterwards, the model fit was  tested with Confirmatory Factor Analysis (CFA) and path analysis. Out of 731 respondents, that were  usable, 368 were selected for EFA and the remaining 363 were selected for CFA and path analysis, where  dataset division was randomly performed with Bernoulli distribution. As a result, there were significant  relationships between all concepts except the aesthetic dimension and privacy risk of the application.


SYNOPSIS Fecal samples from 130 domestic cats from Illinois were examined for coccidia. Three species of Isospora were found: (1) I. felis Wenyon, 1923, with oocysts 38-51 by 27-39 μ with a mean of 41.6 by 30.5 μ and sporocysts 20-26 by 17-22 μ with a mean of 22.6 by 18.4 μ; it was found in 13% of the cats; (2) I. rivolta (Grassi, 1879) Wenyon, 1923, with oocysts 21-28 by 18-23 μ with a mean of 25.0 by 21.1 μ, and sporocysts 14-16 by 10-13 μ with a mean of 15.2 by 11.6 μ; it was found in 3% of the cats; and (3) I. bigemina (Stiles, 1891) Luhe, 1906, with oocysts 12-15 by 10-13 μ with a mean of 13.2 by 11.8 μ. and sporocysts 8-10 by 6-8 μ with a mean of 8.8 by 6.5 μ it was found in 1.5% of the cats.

Four coccidia-free puppies 1.5 months old were inoculated with 100,000 oocysts each of I. felis from the cat, but patent infections did not occur. Partial development of I. felis was not seen in tissue sections of the small intestine of a 5th pup killed 96 hours after inoculation with 150,000 I. felis oocysts. This coccidium is therefore presumably host-specific.


In this study, horizontal wind (U and V), air temperature (T), and relative humidity (RH) modelled by the European Centre for Medium-Range Weather Forecasts Reanalysis Interim (ERA-Interim), the National Aeronautics and Space Administration (NASA) Modern Era Retrospective Analysis for Research and Applications (MERRA), the Japanese 55-year Reanalysis (JRA-55), the National Centers for Environmental Prediction (NCEP) Climate Forecast System Version 2 (CFSv2), and the NCEP Final Operational Global Analysis data and the NCEP Final Operational Global Analysis data (NCEP-FNL) products have been compared with observations at 11 radiosonde stations over the eastern and downstream regions of the Tibetan Plateau (TP) from late June until the end of July during 2011 to 2015. The mean bias of all variables for the five gridded datasets (GDs) in the Sichuan Basin (SCB) is larger than that for the TP. The mean values of U, V, and T from each grid dataset are generally consistent with the radiosonde values, whereas considerable bias in the mean RH exists at upper levels. The diurnal variation of the mean bias and root-mean-square (RMS) error in the basin are stronger than those in the TP and the negative/positive peak usually occurs at 06:00 UTC and 18:00 UTC in the basin or at 12:00 UTC in the TP. The inter-annual variations in the basin are significantly stronger, and the maximum values of the variations usually occur at upper levels or near the surface, except for V. The weather conditions have a crucial influence on the performance of the gridded datasets. The mean bias and RMS error of T in the TP on cloudy days are obviously larger than those during sunny conditions. Considerable but unsteady differences occur in the mean bias and RMS error of U and V in different weather conditions. On average, the four variables in the TP are more sensible to the weather conditions.


A 7-beam receiver, using a cryogenically cooled front end for maximum sensitivity, has been developed by the Commonwealth Scientific and Industrial Research Organisation's (CSIRO) Australia Telescope National Facility (ATNF) Engineering and Development Group and is almost wholly fabricated using the facilities of the ATNF and Australian industry. This new receiver system was recently installed in an antenna situated in Puerto Rico. This paper highlights various design and construction details of the front end, and reports the results of laboratory and telescope testing of the front end cryogenic and electronic systems. This paper also describes measures to minimise self-generated electromagnetic interference (EMI) and shield the receiver from high power radar in close proximity to it's location in the receiver room of the Gregorian dome. INTRODUCTION The United States based National Astronomy and Ionospheric Center's (NAIC), 305m-diameter Arecibo Observatory radiotelescope, operated by Cornell University for the National Science Foundation, is situated in Puerto Rico and is physically the largest and, in some wavelength bands, the most sensitive single dish radio telescope in the world [1]. It is used to study large numbers of sources that are too faint to be seen with other telescopes. The outstanding science achieved with the 13 beam multifeed receiver [2] used on the CSIRO ATNF's 64m-diameter radiotelescope situated at Parkes in central west NSW was the trigger for NAIC to approach the ATNF in order to have the ATNF receiver group construct a multifeed receiver for the Arecibo dish. The Arecibo L-band Feed Array (ALFA) was the name given to this seven feed system that will allow large-scale surveys of the sky to be conducted with unprecedented sensitivity using the Arecibo telescope. The complete ALFA system, operating near 1.4 GHz, consists of a cluster of seven cooled dualpolarization receivers, a fibre-optical transmission system, and digital back-end signal processors. The system will enable deep surveys for a variety of objects in the Milky Way Galaxy and other galaxies for probing cosmology. As such, the multibeam system will have a broad appeal to astronomers from all over the world. THE 7 BEAM RECEIVER SYSTEM Receiver Electronics The receiver has the basic form of a low-noise 14-channel system with both a conversion system and high-resolution spectrometer back end supplied by NAIC. Outputs from a 7element feed-horn array couple via circular waveguides into a cryogenic cryostat where 14 low-noise preamplifiers, 1 for each polarization, and cooled to 12 K, provide an initial 37 dB of gain across a 1200-1800 MHz band with an excess noise contribution of about 5K. The 14 preamplifier outputs are passed through the cryostat walls via a hermetic coaxial connector bulkhead. The required band of observation is 1225 MHz to 1525 MHz and the band defining filters are within the NAIC backend. THE FEED SYSTEM There were two major drivers that determined the outcome of the feed array design study undertaken by Trevor Bird [3] of CSIROs Telecommunications and Industrial Physics Division (as it was at the time). Firstly the feed elements had to efficiently illuminate the subreflector for low spillover which implies a high edge taper. Arecibo has a Gregorian system with the tertiary reflector edge at an angle of 60 degrees with respect to the optical axis. The second driver was the feed aperture diameter was limited in size, since the larger the diameter the further the beams are apart and the greater the scan loss. With a scan loss of 1.5 dB considered an upper limit the feed centre to centre spacing was constrained to be <270 mm. A variety of circular and coaxial horn geometries were investigated and after detailed study by CSIRO and NAIC it was concluded that the largest apertures tended to give best overall performance and that the TE11-mode stepped horn offered the best compromise in performance in terms of spillover efficiency, antenna noise temperature and sensitivity [4]. The final design consists of 7 stepped circular horns arranged in a hexagonal pattern, the apertures of which are located on the telescope focal plane, and couple directly into the cryostat interface through circular waveguide vacuum windows. The front of each feed has a thin (0.14 mm) sheet of Fluorglas to protect against airborne impurities and wildlife. Because of the tropical climate, the facility of introducing dry gas into the space between vacuum window and Fluorglas was included using gas-pipe nipples that protrude from the feed and these nipples can be connected via a manifold. A plan view of the feed horn aperture plane is shown in Fig. 1 and a photograph in Fig. 2. An EMI-tight shroud was added around the feed array that takes the form of a can with EMI gaskets at both ends. It is a three part structure with a whole cylinder attached to the cryostat and another larger diameter cylinder split in two lengthways to allow easy installation between the whole cylinder and an aperture plane plate. It's position means the whole feed array and input waveguide to the cryostat is surrounded. Additionally a plate was supplied to bolt to the front of the feed array with additional EMI gasket to seal around each feed. The plate is manually installed when required as a suitable measure to protect the system during use of the high power radar transmitters. THE CRYOGENIC FRONT END The complete front end consists of the feed-horn array, the cryogenics cryostat containing cooled orthomode transducers and high electron mobility transistor (HEMT) amplifiers, a local monitor and control box and two outrigger, multipurpose electronics modules which contain support electronics, HEMT amplifier bias supplies and a comprehensive monitoring system. The monitoring system indicates the bias states of all transistors in these 14 cooled HEMT amplifiers, as well as temperature and vacuum information on the cryogenic system performance. The cryogenic front end (Fig. 3 and Fig. 4) is situated right at the focal plane area of the telescope optics. It has been Fig 1. Plan view of the 7-beam feed-horn array aperture plane. Note the horn spacing of 260 mm and the horn aperture diameter of 240 mm. All dimensions in mm 24 0


This review is devoted to the analysis of the kinetics of S(IV) (sulfite and bisulfite ions) oxidation by molecular oxygen, ozone, hydrogen peroxide, and peroxymonosulfate in aqueous solutions. Much attention is given to S(IV) oxidation by oxygen. On the basis of the analysis performed, the most reliable rate constants of the reactions involved in the chain-radical process are selected. The ion-molecular mechanism of S(IV) oxidation by H 2 O 2 is considered. This mechanism is shown to closely resemble that of S(IV) oxidation by peroxymonosulfate. Analysis of sulfite oxidation by ozone leads to the conclusion that, in spite of a great number of studies, the mechanism of this reaction remains unclear.


Gravity has huge impact on the accuracy of heavy-duty machine tools. To investigate errors caused by gravity, it is essential to figure out the most influential factor. This paper presents a geometric error modeling for heavy-duty CNC machine tools. Regarding a machine tool as a rigid multi-body system (MBS), the geometric error model has been established by utilizing kinematics chain and homogeneous transfer matrix (HTM). By analyzing the Jacobi matrix, the influence of all the geometric error parameters has been calculated to find out the key geometric error that affect the accuracy most. It is revealed that gravity of beam and tool affect the accuracy of the machine tool most through the ANSYS simulation. It supports a theoretical basis for the further research on error compensation of the key component of a machine tool.


We demonstrate the potential of a hydrothermal method-grown ZnO as a high-spatial resolution imaging device for in-situ soft X-ray laser diagnostics by characterizing the exciton emission patterns. By plotting the emission pattern radii at each position, we estimated the evolution of the beam radius around the focal point. The beam profile of the Ni-like Ag ion plasma laser was estimated from the waist radii as 29 and 21 µm, the divergence angle as 7.2 and 11 mrad and the M2 factor as 47 and 50 in the horizontal- and vertical-axis, respectively. Spatial resolution of the magnifier was estimated to be 6 µm and is expected to improve by optimizing the optics of the magnifier and using a telescope. Our results would enhance the use of ZnO as an imaging device that would play a crucial role in the development and application of soft X-ray light sources.

The crystal structure of beef liver catalase [Murthy, Reid, Sicignano, Tanaka & Rossmann (1981). J. Mol. Biol. 152, 465-499] has now been refined by a restrained parameter least-squares method [Konnert & Hendrickson (1980). Acta Cryst. A36, 344-350] with respect to 2.5 A data. Some extra density was discovered during the refinement process. This was interpreted in terms of a bound NADP molecule [Kirkman & Gaetani (1984). Proc. Natl Acad. Sci. USA, 81, 4343-4348; Fita & Rossmann (1985). Proc. Natl Acad. Sci. USA, 82, 1604-1608]. When the noncrystallographic symmetry was imposed as a constraint, the R factor was reduced to 21.2%. However, refinement of the two crystallographic independent subunits gave a final R factor of 19.1%. The refined coordinates have been re-analyzed for main-chain and side-chain hydrogen bonding, charge distribution, secondary structural element interactions, subunit contacts and molecular packing. The fractional accessibility and the temperature-factor variation are also discussed. The oligomerization process is considered in terms of the unusual quaternary structure. The organization of the heme channel and its relation to the enzyme's catalytic properties have been discussed elsewhere [Fita & Rossmann (1985). J. Mol. Biol. 185, 21-37].

Ag/TiO2 thin film was prepared by the sol-gel method through the hydrolysis of titanium tetraisopropoxide and silver nitrate solution. Spin coating method was used to get uniform film on ITO glass substrate followed by annealing process for 1 hour. After that, all the samples were characterised using GIXRD and FESEM and undergone water contact angle test and MB degradation. Silver ion concentrations were varied to observe the effect on crystalline state, morphology, wettability and photocatalytic properties. The results showed that Ag/TiO2 thin film was in anatase phase and it could degrade nearly 70% of methylene blue after 150 min illumination. The formed Ag/TiO2 thin film has excellent self-cleaning property with compact, continuous, smooth, and good hydrophilicity property.
