Morphological assessment of sexually mature Rutilus frisii kutum Kamenskii 1901 caught from the rivers (Shirud, Khoshkrud, Sepidrud and Chelavand Rivers) flowing in the southwest Caspian Sea region was conducted and sperm volume, total sperm count and sperm concentration of abnormal sperms were determined after exposing the spawners to 60% herbicide butachlor (machete). Spawners under study were maintained in tanks (1000 l) at the Shahid Ansari Teleost Fish Hatchery and exposed to two different concentrations (25% and 75% of its LC50 value) of butachlor.
Results obtained indicate that exposure to high butachlor toxicity (75% of its LC50 value) decreased sperm volume to 0.61 ± 0.42 cc in 2-3 year old fishes and to 0.55 ± 0.42 cc in fishes above 3 years of age, while that in fish exposed to low butachlor toxicity (25% of its LC50 value) decreased to 1.55 ± 0.42 cc in 2-3 year old fishes and to 1.28 ± 0.42 cc in fishes above 3 years of age. The sperm volume under normal conditions in R. frisii kutum is 4.6 ± 0.42 cc in 2-3 year olds and 4.58 ± 0.42 cc in fishes above 3 years of age. The total sperm count in R. frisii kutum is 39.74 ± 2.5 billion spermatozoa/cc in 2-3 year olds and 42.99 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. When exposed to high butachlor toxicity, total sperm count dropped to 16.92 ± 2.5 billion spermatozoa/cc in 2-3 year olds and to 15.98 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. Similarly total sperm count in R. frisii kutum exposed to low butachlor toxicity was recorded as 23.6 ± 2.5 billion spermatozoa/cc in 2-3 year olds and 29.4 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. Under normal conditions, on the basis of morphology, spermatozoa showed only 10 ± 1.92% of abnormal sperms. The number of
abnormal sperms increased by 28.6 ± 1.92% in fishes exposed to high butachlor toxicity, while that in fishes exposed to low butachlor toxicity increased by 19.7 ± 1.92% in 2-3 year olds and 16.6 ± 19.2% in fishes above 3 years of age.
It is evident from the results obtained that increase in level of pollution caused a decrease in sperm volume but an increase in the percentage of abnormal sperms.
Results obtained indicate that exposure to high butachlor toxicity (75% of its LC50 value) decreased testostron hormone to 0.31 ± 0.22 ng/ml in high butachlor toxicity, and to 0.45 ± 0.22 ng/ml in low butachlor toxicity (25% of its LC50 value). Testostron hormone dropped to 0.53 ± 0.22 ng/ml in 2-3 year olds and to 0.79 ± 0.22ng/ in fishes above 3 years of age. The testostron hormone under normal conditions in R. frisii kutum is 2.7 ± 0.22 ng/ml.
It is evident from the results obtained that increase in level of pollution caused a decrease in testostron hormone


Computer-based testing is a method of administering tests in which the responses are electronically recorded, assessed, or preferably both. The assessment is a testing tool which checks student´s knowledge, measures their progress and gathers information from students. The most important attributes to consider when creating an assessment in computer-based environment is threefold; the structure and types of questions included, deployment and setting options, and grading assessments and availability of multiple attempts. The paper focuses on computer-based testing methods applied in English language course at Faculty of Informatics and Management, University of Hradec Kralove, in the Blackboard learn environment to monitor and check students 'proficiency of key language competences. The key language competences defined by the Common European Framework of Reference for Languages (CEFR) are tested with a special view on students´ individual learning styles. Keywords: Computer-based testing methods; key language competences; Blackboard learn environment; individual learning styles;


Conclusions Observations clearly demonstrate thatthe PSIhas had the desired effect on the TIDEmeasurements: Low-energy ions that would otherwise be unobservable are seen. Equally clear is that the PSI modie es the sheath structure around the POLAR spacecraft in ways that also affect measurements made by other instruments, such as the PWI and the EFI. This implies that it will also have quantitative consequencesfortheTIDEobservations.TheEFIobservationssuggest that the TIDE core ion measurements will not be signie cantly affected unless ion energies are much less than 5 eV. Core electrons are more affected by the PSI sheath, and at lower oute ow speeds the ions will also be ine uenced, requiring a better understanding of the sheath. A physical model has been presented that explains qualitatively the origin of the anisotropy found in observations with the PSI operating. This model can be used to guide the development of a detailed and accurate numerical model, which in turn can be used to develop modie cations to the analysis to compensate for the PSI effects. The best understanding of the PSI sheath will come from synoptic operations of the PSI and dedicated analysis of the complete POLAR plasma data set.

Lung transplantation has become a real alternative for some patients with end-stage lung disease to improve their quality of life and long-term survival. The emergence of powerful immunosuppressants that operate in different ways of alloimmune response has been one of the factors responsible for the progressive improvement of survival. However, the favorable results of other organs have not been corroborated in lung transplantation, where acute and chronic rejection rates are high and are one of the most important factors responsible for the morbidity and mortality. The two major complications associated with lung transplantation are rejection and infection. Both complications can cause death, highlighting the importance of an adequate immunosuppressive therapy to improve medium and long-term survival. Therefore, the key for successful lung transplantation is to achieve the suitable level of immunosuppression that allows preventing rejection without increasing infections or other side effects. From the existing data on induction therapy in lung transplantation it seems to be a good option to prevent or reduce acute and chronic rejection and to decrease the nephrotoxicity related to the use of calcineurin inhibitors Nowadays, induction therapy seems to be a good option to prevent or reduce acute and chronic rejection and to decrease the nephrotoxicity related to the use of calcineurin inhibitors.

Introduction A modern total knee replacement system was introduced in 2012 in order to improve the mechanics of total knee replacement (TKR). The purpose of this study was to assess the early clinical and radiographic outcomes of patients who have been treated with this modern TKR system at two years postoperatively.

Methods Patients who received this TKR system between June of 2012 and September of 2014 were included in this prospective registry-based follow-up study. Demographics, component, and surgical data were collected. Radiographic outcomes were also assessed. Patient reported outcome measures (PROMs) of all patients with 2-year follow-up data were collected. Reasons for revision and overall survival at 2-years were evaluated.

Results The study population consisted of 290 patients (307 knees). The mean age was 66 years and 61% were women. 250 patients received cruciate retaining and 57 patients posterior stabilized implants. The median tibiofemoral axis was in 4° valgus and the femoral component was in 5° valgus and 2° flexion. The median coronal and sagittal alignment of the tibial component was −1° varus and −5° slope, respectively. Most patients had tibial components that fit the tibial resection. At one year, 7 of 80 knees had a radiolucency in the tibia or femur. At two years, two of 30 knees had a radiolucency in the tibia or femur.

Mean PROMs for thirty-six patients at two years were: EQ-5D WHI 0.76 (range 0.31–1.00), EQ-5D VAS 82 (range 48–98), UCLA activity score 5.3 (range 2–10), KOOS pain 70.9 (22–100), symptoms 69 (14–96), ADL 74.2 (18–100), sports 51.4 (0–100), and QoL 59.8 (0–90). Cumulative 2-year implant survival was 97.1%. There were 7 revisions for infection and 2 revisions due to an unsatisfactory clinical outcome.

Conclusion Clinical and radiographic outcomes at two years were good, and overall implant survival was excellent.


A double current method is presented for absolute measurements of the current dependence (power variation) of dc resistors. Based on the resistance measurement principle of a direct current comparator (DCC), and adding another DCC-based extender with a turn ratio 1:1, the testing current in resistors to be tested is accurately doubled. Through three comparative measurements with two reference standard resistors connected in series as Kelvin resistive bridge inner arms, the change of resistance caused by doubling the currents is measured. Cyclically done, absolute measurement of current or power factor is realized. Examples of the current dependence of some commercial low-temperature coefficient 1 Ω standard resistors are given using the presented method and their results are analyzed.


The manuscript presents the software implementation of Pspise-based models in the Python programming language. To demonstrate the model transformation process, examples of electrical circuits that present current and voltage resonance are considered. The implementation experiments were conducted based on models implemented in LTspice. Simulation results using Python are obtained that are similar to those from other software environments specialized for modelling electrical and electronic circuits.


People require transportation to move from one place to another place nowadays. As the population expands, so does transportation across the country. Despite the high demand for vehicles, the number of accidents are increasing due to the lack of safety precautions. Moreover, major accidents occur for two-wheeler drivers because two-wheelers lack safety precautions that four-wheelers have. Many research studies that are conducted recently to determine the cause of accidents concluded that driving recklessly in crowded areas causes road accidents. The major goal of this research work is to minimize the road accidents and prevent road accidents while ensuring driver safety. The proposed model enhances human safety while driving is by employing Arduino UNO and IoT. The vehicle will only start if the driver wears helmet and not intoxicated. To track the vehicle's current location, GPS module is used. To avoid accidents due to vehicle overspeed, the speed of vehicle is continuously monitored. In a particular zone, the driver will be alerted to reduce the speed.


Covid-19, which is still a pandemic today, brings a change in lifestyle to the social order. People are required to adopt new habits (new normal) to be able to live productively. The new normal era began to be enforced by the government with the issuance of the Decree of the Minister of Health. Ensure a quality work process for each company by utilizing human resources as best as possible with some considerations.  The study of retail companies and national DNA, to know and understand the strategy of national private companies to improve the performance of its employees in the face of the new era of normal As well as the process of multinational private companies to improve the performance of its employees at the beginning of the new normal era. The research will impact the development efforts of a healthy working environment by creating an office with the concept of open space,  modern, ecofriendly and high-technology. In addition, the idea of 3T (Right Quality, On Time, On Target) and 3K (Communication, Coordination, Collaboration) must also be applied so that the talents can make a positive contribution to the company both in the era of covid 19 and in the new normal period.


Disclosed are process controls for controlling the continuous preparation of nylon salt solution. The process controls include feed forward controls. A model is generated to achieve a target pH and/or salt concentration. Feed rates are set for each of a dicarboxylic acid monomer, a diamine monomer, and/or water to a single continuous stirred tank reactor. The dicarboxylic acid is metered, based on weight, from a loss-in-weight feeder to the reactor. The nylon salt solution is formed continuously and has low variability from a target pH and/or a target salt solution concentration. The nylon salt solution is transferred directly to a storage tank, without further monomer addition, pH adjustment, or salt solution adjustment after exiting the continuous stirred tank reactor.


Alkaloids were isolated and identified from Mentha spicata leaves. Qualitative analysis, thin layer chromatography(TLC), functional groups test and infra-red spectrum were carried out for identification of these alkaloids. TLC results showed presence of two alkaloidic compounds in alkaloids extract. The Bioactivity and biochemical effect of alkaloids, was investigated towards four pathogenic fungi. The maximal inhibitory concentration was measured to be (250 mg/ml) and the Bioactivity of this concentration was recorded against pathogenic fungi represented by Aspergillus fumigatus, Candida albicans, penicillum crysosporm and Aspergillus niger with inhibition zone diameters equal to (23, 15, 15 and 11 mm) respectively. Therefore, the alkaloidic compounds isolated can be used as an herbal theuraputic substituent to the different diseases caused by these fungi but this work demands further clinical and pharmaceutical studies.


Although new diagnostics may advance the time of diagnoses in selected patients, they will increase the frequency of false alarms, overdiagnosis, and overtreatment in others. Bjorn Hofmann and H. Gilbert Welch explain how to minimise harm


More information is needed about factors influencing real-life implementation and program impact of interventions effective in controlled study conditions. Ongoing national implementation of an evidence-based HIV prevention program targeting grade 6 students in The Bahamas offers the opportunity to examine patterns of implementation and relate them to student outcomes. Data were collected from 208 grade 6 teachers, 75 grade 7 teachers and 4,411 grade 6 students followed over two years. Mixed-effects modeling analysis examined the association of teachers' patterns of implementation with student outcomes. High quality program implementation in grade 6 (high implementation dosage and fidelity) was significantly related to student outcomes six and 18 months post-intervention. Quality of implementation of the booster session in grade 7 was also significantly related to student outcomes in grade 7. Quality of delivery of the brief booster session a year after initial implementation is important in maintaining or resetting the student outcome trajectory.


https://doi.org/10.20344/amp.13957 ABSTRACTIntroduction: In December 2019, an outbreak of pneumonia caused by a novel coronavirus occurred in Wuhan, the capital of Central China's Hubei Province and has been declared a public health emergency of international concern by the World Health Organization since January 2020. Material and Methods: A comprehensive search using the PubMed database was carried out to summarize the latest published information about the epidemiology, definition, pathogenesis, clinical characteristics, treatment options, prognosis and prevention of coronavirus disease 2019. Discussion: This new strain of coronavirus, named severe acute respiratory syndrome coronavirus 2, enters human cells that express angiotensin-converting enzyme II receptors, which exist in the respiratory, gastrointestinal and genitourinary tracts and heart, causing coronavirus disease. Transmission occurs essentially through the respiratory tract and the main symptoms are fever, cough and dys- pnea. Diagnosis is based on epidemiological, clinical and imaging features and confirmed by nucleic acid testing. Conclusion: Despite intensive research, the exact origin of the virus and pathophysiology of coronavirus disease is not yet completely known, and clinically approved vaccines and drugs that target severe acute respiratory syndrome coronavirus 2 are nucleicos. não conhecida vírus, doença direcionados a esta nova estirpe de is nucleic acid testing by reverse transcription polymerase chain reaction (RT-PCR) using respiratory samples. 12 Upper respiratory samples include nasopharyngeal and oropharyngeal swabs, nasopharyngeal washes and nasal aspirates while sputum, bronchoalveolar lavage and tracheal aspirates represent lower respiratory tract samples. 12 Yang et al compared the sensitivity of sputum, nasal and oral swabs for detection of SARS-CoV-2 and demonstrated that sputum was the most reliable sample, followed by the nasal swab. 48 Because RT-PCR of viral nucleic acid has limited sensitivity (60-70%), the search for new testing methods is currently evolving. 44 Yu et al compared RT-PCR with ddPCR (droplet digital PCR) and reported that the latter was more useful in detecting the virus in samples with lower viral loads. 49 Zhao et al detected the appearance of total antibodies, immunoglobulin M (IgM) and immunoglobulin G (IgG) against SARS-CoV-2 with a median seroconversion time of 11, 12 and 14 days, respectively. 50 The use of serological tests in conjunction with nucleic acid testing has been suggested in order to improve the sensitivity of the COVID-19 diagnosis. 50


Linear Elastic Fracture Mechanics (LEFM) describes the propagation of a crack exists in a material, and this propagation is proportional to the range of stress intensity factor. In LEFM there are several models that describe the evolution of an initial crack, as the models of Paris-Erdogan and Forman that are formulated and solved by the determination of an Initial Value Problem (IVP). For few practical applications, it is possible to obtain an exact solution of the IVP, and in most applications; approximate numerical solutions are used, which can reflect on aspects such as the time and the computational cost. Therefore, this paper presents a theoretical result establishing upper and lower bounds for the crack size function for Forman model. The bounds are very narrow, hence accurate crack size approximations can be obtained from only two stress intensity factor evaluations. This leads to a huge gain in a computational effort for numerical crack growth computations. Two examples are used within to explore the accuracy and efficiency of the proposed solution for the crack growth initial value problem.


A 65-year-old woman was referred to the Oral Surgery of Yamaguchi Prefectual Hospital in July, 1979, for consultation with regard to a painless sweliing of the left maxilla. She first felt painless swelling of the left maxilla in july, l978, but she had no pain. So she didn't ask fDr any treatment for it. In May, 1979, the swelling began to get larger and larger, and so she finally consulted our clinic (Fig. 1). Her past medical and dental history was unremarkable. Clinically, her face was asymmetrical. An intraoral examination found a diffuse swelring from the lateral incisor to second premolar on the left upper vestibule. After palpation, it was felt as parchment crepitation and fluctuation. When the cystic lesion was punctured, about 5 ml of yellow-brown transparent fluid containing cholesterin crystal was obtained (Fig. 2).


The error of decommissioning is a serious problem that is often faced in medicine. In the face of these problems, information technology has a very important role. One of the information technologies that can be used is to use the machine learning classification algorithm K-Nearest Neighbor KNN. KNN is a type of machine learning algorithm that can be applied to problems with classification and regression prediction. The classification of types of drugs for patients greatly affects the health of the patient. The patient data is processed and transformed to numbers, which are then divided into training data and test data from 90:10, 80:20, 70:30 and using the Cross Validation model. KNN works through the nearest neighboring value with a value of k = 3 calculated by the calculation of Euclidean Distance, and then evaluated using the Confusion Matrix. The performance of the KNN algorithm resulted in the highest Accuracy value of 98.33%, a Precision value of 98.8%, a Recall value of 96.2%, and an F-measure value of 97.48%. The performance is obtained from the sharing of training data and 90:10 test data. The data share results in high performance compared to other data shares, including using the Cross Validation model. And the lower the k value, the higher the value of the resulting performance. The results show that the performance of the KNN algorithm is working well.


The rapid development of internet finance has caused great impact on the current business model of commercial banks, therefore, how to transform the business model of commercial banks and meet the challenges from internet finance become an urgent issue that needs to be addressed facing all commercial banks.

The independent National Commission on Fiscal Responsibility and Reform created by President Barack Obama is to hold its first meeting on Tuesday. The co-chairmen of the 18-member panel told "Fox News Sunday" that everything had to be on the table as it considers ways to reduce huge deficits and mounting debt. "We're not going to say we're going to grow our way out of this," said former Republican Senator Alan Simpson. "Hell, we could have double (-digit) growth for 30 years and never grow our way out of this."


Title:Change strategies in the transition towards a cashless banking systemLevel:Final assignment for Bachelor Degree in Business AdministrationAuthor:Elin Lanstrom och Vildana SmailagicSupervisor:Stig SorlingDate:August 2013Aim:In our study, we compare what it is that drives a bank to implement changes in their business, what problems these changes may bring, and how organizations deal with these. We do this by studying how different banks choose to relate to the handling of cash.The questions we ask ourselves are: What lies behind the decision to make changes in cash management? How is the change implemented in practice? What do banks think this change will mean for the future?Method:The study was conducted with the help of a qualitative scientific method. We conducted interviews with representatives of four banks, and made use of secondary data in the form of scientific literature and scientific articles.Result & Conclusions:Organizations implement changes in order to adapt and achieve balance with their environment but also within the organization itself. Our study shows that the decision to introduce cashless branches is mainly a result of banks' efforts to become more cost efficient. Practically banks' daily activities aren't affected as much because cash management is not a big part of it in any event. Although more and more banks choose not to hold cash at their branches, our study shows that most of them still believe that cash will survive for a long time to come.Suggestions for future research:It would be interesting to conduct a study that highlights this issue from a perspective that compares the expectations expressed by our respondents with the actual outcome.Contribution of the thesis:This study helps to provide a deeper understanding of the difficulties that may arise in the context of change.Key words:cashless, change process, change strategies, cost efficiency, institutional change


Cloud computing paradigm is still an evolving paradigm but has recently gained tremendous momentum due to its potential for significant cost reduction and increased operating efficiencies in computing. However, its unique aspects exacerbate security and privacy challenges that pose as the key roadblock to its fast adoption. Cloud computing has already become very popular, and practitioners need to provide security mechanisms to ensure its secure adoption. In this chapter, the authors discuss access control systems and policy management in cloud computing environments. The cloud computing environments may not allow use of a single access control system, single policy language, or single management tool for the various cloud services that it offers. Currently, users must use diverse access control solutions available for each cloud service provider to secure data. Access control policies may be composed in incompatible ways because of diverse policy languages that are maintained separately at every cloud provider. Heterogeneity and distribution of these policies pose problems in managing access policy rules for a cloud environment. In this chapter, the authors discuss challenges of policy management and introduce a cloud based policy management framework that is designed to give users a unified control point for managing access policies to control access to their resources no matter where they are stored.

Twenty-five kilometers north of Dublin, a masterpiece of Stone Age engineering rises from the hills: a circular structure 12 meters high, almost the area of a U.S. football field, and made up of more than 200,000 tons of earth and stone. Some of the first farmers to arrive in Ireland erected this monument, called Newgrange, nearly 1000 years before Stonehenge or Egypt9s first pyramids were built. Archaeologists have assumed it was a ceremonial site and communal tomb—an expression of an egalitarian society. Now, DNA from a middle-aged man buried in 3200 B.C.E. at the center of this mighty mound suggests otherwise. His genes indicate he had parents so closely related they must have been brother and sister or parent and child. Across cultures, incest is almost always taboo—except in inbred royal families. Its genetic traces at Newgrange suggest social hierarchy took hold in Ireland earlier than thought, according to a new study that also includes DNA from 40 other ancient Irish tombs.


A strain of sulfate-reducing bacterium was isolated from the sewage of an anaerobic baffle reactor(ABR). The morphological and biochemical characteristics as well as 16S rDNA sequence of the strain was studied.The cells are vibrioid-shaped or rod shape with the size of(0.5~0.7)μm×(1.4~1.9)μm.The strain is gram negative, motile and doesn't form spore.The best pH value for growth is 7.0~8.0.When the initial[SO_4~(2-)]is 2000mg/L, the highest OD_(600nm) is 1.206 and the SO_4~(2-) removal efficiency is up to 71%.The strain can use lactic acid,pyruvatic acid,butyric acid,acetic acid,ethanol,methanol and glucose as electron donor respectively.Lactic acid is the most suitable electron donor to reduce SO_4~(2-),the SO_4~(2-) removal efficiency is up to 91.4%when lactic acid is the sole carbon source.The results of 16S rRNA sequence and phylogenetic analysis show that the strain is the closest relative to Desulfovibrio sp.with 96.0%sequence similarity.


Background and purpose — Growth modulation with a medial malleolar screw is used to correct ankle valgus deformity in children with a wide spectrum of underlying etiologies. It is unclear whether the etiology of the deformity affects the angular correction rate with this procedure. Patients and methods — 79 children (20 girls) with ankle valgus deformity had growth modulation by a medial malleolar screw (125 ankles). To be included, patients had to have undergone screw removal at the time of skeletal maturity or deformity correction, or a minimum follow-up of 18 months, and consistent radiographs preoperatively and at the time of screw removal and/or follow-up. The patients were assigned to 1 of 7 groups according to their underlying diagnoses. The lateral distal tibial angle (LDTA) was analyzed preoperatively, at screw removal, and at follow-up. Results — Mean age at operation was 11.7 (7.4–16.5) years. The average lateral distal tibial angle normalized from 80° (67–85) preoperatively to 89° (73–97) at screw removal. The screws were removed after an average time of 18 (6–46) months, according to an average rate of correction of 0.65° (0.1–2.2) per month. No significant differences in the correction rate per month were found between the groups (p = 0.3). Interpretation — Growth modulation with a medial malleolar screw is effective for the treatment of ankle valgus deformity in patients with a wide spectrum of underlying diagnoses. The individual etiology of the ankle valgus does not appear to affect the correction rate after growth modulation. Thus, the optimal timing of growth modulation mainly depends on the remaining individual growth and on the extent of the deformity.


The thermodynamics of the Kerr-AdS black hole is reformulated within the context of the formalism of geometrothermodynamics (GTD) and the cosmological constant is considered as a new thermodynamical parameter. We conclude that the mass of the black hole corresponds to the total enthalpy of this system. Choosing appropriately the metric in the equilibrium states manifold, we study the phase transitions as a divergence of the thermodynamical curvature scalar. This approach reproduces the Hawking-Page transition and shows that considering the cosmological constant as a thermodynamical parameter does not contribute with new phase transitions.

We report on molecular beam epitaxial growth of AlInSb/GaInSb metamorphic high-electron-mobility-transistor structures for low power, high frequency applications on 4 in. GaAs substrates. The structures consist of a Ga0.4In0.6Sb channel embedded in Al0.4In0.6Sb barrier layers which are grown on top of an insulating metamorphic buffer, which is based on the linear exchange of Ga versus In and a subsequent exchange of As versus Sb. Precise control of group V fluxes and substrate temperature in the Al0.4In0.6As1−xSbx buffer is essential to achieve high quality device structures. Good morphological properties were achieved demonstrated by the appearance of crosshatching and root mean square roughness values of 2.0 nm. Buffer isolation is found to be >100 kΩ/◻ for optimized growth conditions. Hall measurements at room temperature reveal electron densities of 2.8×1012 cm−2 in the channel at mobility values of 21.000 cm2/V s for single-sided Te volume doping and 5.4×1012 cm−2 and 17.000 cm2/V s for double-sided ...


In this work we investigate software aging phenomena inside the Java Virtual Machine (JVM). Starting from an experimental campaign on real world testbeds, this work isolates the contribution of the JVM to the overall aging trend, and identifies, through statistical methods, which workload parameters are more relevant to aging dynamics. Experimental results show that the Sun Hotpost JVM experiences software aging phenomena. A consistent memory depletion trend (up to 50 KB/min) has been observed during periods of low garbage collector activity; the Just-In-Time compiler is also responsible for a lighter, but not negligible, memory depletion trend; finally, a consistent throughput loss (up to 24 KB/min) has been observed.


Based on acoustic radiation modes, the surface contribution method has been developed to predict the surface contributions to the radiated sound power from a vibrating structure. In this work, the surface contribution method is used to identify the sound field on a vibrating structure submerged in a heavy fluid. It was recently found that surface contribution method was not able to predict the surface contributions at low frequencies when the structural wavenumber is higher than the acoustic wavenumber. In this paper, the acoustic radiation efficiencies calculated for different numbers of integration points are compared and used to compute the surface contributions to the radiated sound power. The radiated sound power obtained from both the surface contribution and the active intensity methods are compared. Numerical results for a fully coupled finite element/boundary element model of a cylindrical shell with hemispherical end closures submerged in water show that the surface contribution method can also be successfully applied at low frequencies.


As power becomes an increasingly important design factor in high-end supercomputers, future systems will likely operate with power limitations significantly below their peak power specifications. These limitations will be enforced through a combination of software and hardware power policies, which will filter down from the system level to individual nodes. Hardware is already moving in this direction by providing power-capping interfaces to the user. The power/performance trade-off at the node level is critical in maximizing the performance of power-constrained cluster systems, but is also complex because of the many interacting architectural features and accelerators that comprise the hardware configuration of a node. The key to solving this challenge is an accurate power/performance model that will aid in selecting the right configuration from a large set of available configurations. In this paper, we present a novel approach to generate such a model offline using kernel clustering and multivariate linear regression. Our model requires only two iterations to select a configuration, which provides a significant advantage over exhaustive search-based strategies. We apply our model to predict power and performance for different applications using arbitrary configurations, and show that our model, when used with hardware frequency-limiting, selects configurations with significantly higher performance at a given power limit than those chosen by frequency-limiting alone. When applied to a set of 36 computational kernels from a range of applications, our model accurately predicts power and performance, it maintains 91% of optimal performance while meeting power constraints 88% of the time. When the model violates a power constraint, it exceeds the constraint by only 6% in the average case, while simultaneously achieving 54% more performance than an oracle.


ABSTRACT As the use of mobile device is increasing rapidly, the number of users is also increasing. However, most of the app stores are using recommendation of simple ranking method, so the accuracy of recommendation is lower. To recommend an item that is more appropriate to the user, this paper proposes a technique that reflects the weight of user information and recent preference degree of item. The proposed technique classifies the data set by categories and then derives a predicted value by applying the user's information weight to the collaborative filtering technique. To reflect the recent preference degree of item by categories, the average of items' rating values in the designated period is computed. An item is recommended by combining the two result values.

A new species, Xylodes (Diegous) korinae Zahradník & Trýzna sp. nov. (Bostrichoidea: Ptinidae, Ptininae, Ptinini), from east Madagascar is described, illustrated and compared with other species from the subgenus Diegous Pic, 1896. Male and female genitalia are studied and illustrated. Keys to morphologically similar genera from Madagascar and adjacent areas, to both subgenera of the genus Xylodes Waterhouse, 1876, and to all species of the subgenus Diegous are presented. Ecological notes, including photographs of habitats of the new species are also provided.


In this paper a semantic-probabilistic network for event recognition is proposed. The approach uses pre-defined domain ontology to describe the events and scenarios in the scene as a hierarchical decomposition of simple concepts and variables and then perform an automated conversion of the ontology into a Bayesian network. A novel approach to Bayesian network nodes weights calculation is used based on the weighted relation between concepts of the ontology. We then test the performance of our approach to recognize gestures in a human gesture recognition system.


Gas-permeable polymeric membranes containing carboxyl groups which are suitable for enzyme immobilization were investigated in order to use them as gas electrode membranes in biosensors. Carboxylated polyurethane (CPU) was synthesized via a reaction between 2,2-bis(hydroxymethyl)propionic acid as a chain extender and prepolymers prepared from polycarprolactone (Mn=2,000) and 4,4'-diphenylmethane diisocynate. It was difficult to prepare membranes from the pure CPU because of its high elasticity and cohesion. However, transparent free-standing membranes were easily prepared from the blend solutions of CPU and carboxylated poly(vinyl chloride) (CPVC) in tetrahydrofuran. Both elasticity and cohesion of the CPU/CPVC membranes were decreased with increasing the content of CPVC. DSC experiment suggests that CPU and CPVC may be well mixed. Permeability coefficients for O 2 and CO2 (PO2 and PCO2) in the membranes increased as the proportion of CPU increased. The addition of dioctyl phthalate (DOP), a plasticizer, significantly enhanced the P O2 and PCO2 which were 4.4 and 30 Barrer, respectively, in the CPU/CPVC (80/20 wt/wt) membranes containing 20% of DOP at 25 o C and 100 psi. Thus this type of membranes may have a potential for the use as gas electrode membranes in biosensors.


From a comparison of cambial cells and their derivatives between naturally occurring dwarf trees and normal ones, it was concluded that tracheids in the annual rings of dwarf trees are shorter, narrower and fewer than those of normal trees. The frequency of anticlinal division and loss of cambial initials is low during differentiation of xylem cells from cambial initials in dwarf pines. The length and intrusive growth of fusiform initials are slightly less than those of normal trees. Thus, it is concluded that the shortening of tracheids in dwarf trees is due to the fact that cambial initials are themselves shortened and that intrusive growth during differentiation of xylem mother cells has occurred.


Chapter 4 combines the archaeological and art historical evidence for the Baths' decorative program with the methodologies of urban anthropology and cognitive space theory to reconstruct the Baths of Caracalla as both a conceptual and physical space. This theoretical frame illuminates the phenomenological experience of the Baths' spaces and their reception by the Roman public by investigating certain decorative devices and display formats that were central to the visual experience of the Baths. The chapter demonstrates how the dynamic possibilities of the decorative program could reiterate and reinforce the message of the iconographical program as a bather progressed through the complex.


The purpose of this report is to record in the literature by means of visual impressions two further diagnostic features in the syndrome of sickle cell anemia, which were brought out in two cases that I have observed. These are, first, the so-called hair on end appearance in roentgenograms taken of the skulls of patients with long-standing involvement and, secondly, widespread vascular changes. Roentgenograms showing similar changes have been published in roentgenologic journals (Rose, 1 Grinnan, 2 Vogt and Diamond, 3 Le Wald 4 ), but so far only verbal descriptions have been given in clinical journals, except by Moore. 5 The vascular changes have not previously been described, as far as I have been able to discover. The roentgenograms of the skulls of my patients showed an increase in the thickness of the calvarium in all areas. There was a loss of continuity of the outer table of the skull.


Primary antiphospholipid syndrome, defined as the presence of antiphospholipid antibodies with recurrent thrombosis in patients who have no clinical or serologic features of systemic lupus erythematosus, is now a medically recognizable and treatable disorder. 1 The syndrome is associated with a high incidence of recurrent arterial and venous occlusions, with cerebrovascular thrombi occurring second in frequency only to deep vein thrombi.2 Current recommendations are to screen for antiphospholipid antibodies in all patients younger than 45 years (even those with risk factors for thromboses) who have had a thrombotic event, as well as in patients who have clinical features of systemic lupus erythematosus or who have had more than two miscarriages.3 The case presented here illustrates the challenge and importance of recognizing primary antiphospholipid syndrome in a family practice.

Objective To evaluate influence of finasteride on extracellular matrix(ECM) in benign prostate hyperplasia(BPH) patients and study the mechanism.Methods Twenty BPH patients needing surgery were randomly divided into 2 groups according to the sequence of hospitalization from June 2008 to March 2009.The finasteride group and the placebo group had 10 patients each.Transurethral resection prostate(TURP) were performed and the specimens were collected after 4 weeks of drug administration.Moreover,6 normal prostatic tissues were selected.Expressions of fibronectin(FN),collagen(CL),matrix metalloproteinase-2(MMP-2) and tissue inhibitor of metalloproteinase-2(TIMP-2) were studied in prostatic tissues in all groups(including the normal group) by immunohistochemistry and image analysis system.Results Expressions of FN and CL were significantly higher than those in the normal group(P0.01),while expressions of MMP-2 and TIMP-2 were not significantly different between them(P0.05).Compared with the placebo group,expressions of FN and CL in the finateride group were significantly lower than the placebo group(P0.01),while expressions of MMP-2 and TIMP-2 were significantly higher(P0.01).Conclusions BPH is related to ECM depositing.Finasteride can decrease ECM of BPH and refrain it from depositing.Possibly,the principle is that finasteride can promote the degradation of ECM.


Abstract This study investigated the resetting process of the articles' parameters by Chinese English learners with a Forced Choice Elicitation Task on the basis of the Article Choice Parameter and Fluctuation Hypothesis proposed by Ionin, Ko and Wexler (2004). It was found that Chinese English learners fluctuate between definiteness and specificity, the two parameter-settings of articles. Our findings are consistent with the Fluctuation Hypothesis. Their performance can be accounted for under the theoretical framework of Distributed Morphology. The difficulty in article acquisition lies in the fact that Chinese English learners can not easily identify the correct features in the specification of syntactic terminal nodes as well as the vocabulary items, but they possess the syntactic knowledge and they can access the definiteness parameter setting with enough L2 input. Chinese English learners' interlanguage syntax is not impaired and UG full access is supported.


There has been a major effort in the past few years to provide more emphasis on STEM related careers, especially in terms of women entering STEM fields. It has been gratifying to see positive results from educational efforts to open opportunities for women, with many more young women entering the classes previously believed to be reserved for men. The numbers are still small in contrast to men in engineering classes. This paper will examine some of the efforts being made in industry and education to achieve a greater number of women in engineering for a lifetime career and discuss some women who have been instrumental in getting more women into engineering careers.


A method for determining if a CHK-1 is inhibiting its molecular target CHK-1, the method comprising: (a) determining the presence of a molecule of CHK-1 phosphorylated in a first sample from a test patient with cancer who has received a DNA damaging agent, and (b) determining the presence of CHK-1 phosphorylated in a second sample from the test patient with cancer who has received a DNA damaging agent and an inhibitor of CHK-1 wherein an increase in the amount of phosphorylated CHK-1 in the second sample compared to the first sample is indicative that the CHK-1 inhibitor is inhibiting its molecular target CHK-1.


Current vehicle energy absorbers have two defects during collision, such as only 70 % collapsed in its length and high initial peak load. It is because present energy absorbed column is the most primitive from the point of Origami structure. We developed the column so called Reversed Spiral Origami Structure; RSO which solves these 2 defects. However, for RSO, the manufacturing cost of hydroforming in the existing technology is too expensive to be applied in real vehicle structure. To address the problems, a new structure, named Reversed Torsion Origami Structure (RTO), has been developed, which can be manufactured at a low cost by using simple torsion. This structure is possible to replace conventional energy absorbers and it is expected to be widely used such as not only in automobile structures but also in building ones.


Audio file size is relatively larger when compared to files with text format. Large files can cause various obstacles in the form of large space requirements for storage and a long enough time in the shipping process. File compression is one solution that can be done to overcome the problem of large file sizes. Arithmetic coding is one algorithm that can be used to compress audio files. The arithmetic coding algorithm encodes the audio file and changes one row of input symbols with a floating point number and obtains the output of the encoding in the form of a number of values greater than 0 and smaller than 1. The process of compression and decompression of audio files in this study is done against several wave files. Wave files are standard audio file formats developed by Microsoft and IBM that are stored using PCM (Pulse Code Modulation) coding. The wave file compression ratio obtained in this study was 16.12 percent with an average compression process time of 45.89 seconds, while the average decompression time was 0.32 seconds.


In organization of every kind, quality can be regarded as a means to an end -customer satisfaction in all aspects of a product or services. It should be all-pervasive, covering not only the design, performance and reliability of a product or service but the constant improvement of what is on offer. Quality is about attitudes, culture and commitment within an organization. It applies in all organizations: manufacturing, service and public sector, including Government. The world has entered into new millennium- an era of unprecedented changes, upheavals and uncertainty. In the today's world we are highly sensitive about environmental pollution caused by industrial and other sources. And when it comes to chemical industries, the concern for environmental pollution is still more since these industries are highly pollution prone. A good quality system in chemical industries will not only serve the common objectives of customer satisfaction, higher profits and growth but also will be able to control the pollution problem to a considerable extent. The paper first identifies the ideal attributes of a quality system with special reference to chemical industrial units and then suggests the measures to refine these attributes, so as to enhance the productivity.


Yoga is the great philosophy which has a history running beyond to eras Vedas. Some of the practices mention in yoga philosophy can be found in Upanishad literature. Facts mention in yoga philosophy to uplift the individual and social health gathered from ayurvedic commentaries and Sanskrit literature. Aim of this study wears to review the importance of following yama and niyama mention in the Aṣṭāṅga yoga to enhance physical, mental and spiritual wellbeing of the individuals and society. According to yoga human being is created by two entities which are called as dosha and prakurti. Observe of positive values and avoidance of negative has been mention in yoga philosophy in order to uplift the good conduct of living being pacifying the above two entities. Achārya charaka has mention there are five principles which be followed by individuals and that liberation has obtain following yoga. Practice in the yama strive us towards the healthy life, mind strengthening, and our powers of awareness, win and physical wellbeing by following them. We can fortify character improve our relationships with others in trust worthy way. All the practices of yama are related to the relationship in between the follower and his external world. Niyama is the second limb of ashtanga yoga is focus on the internal environment of body, mind and spirit. It helps us to build up to self disciplean and inner strength of individuals. Following niyama can practice to reject unwanted emotions like anger, fighting, lazy and mind can stay in one thing. In finally can obtain moksha with practice of niyama.Following both yama and niyama people can improve their health by enhancing their physically mentally and spiritually wellbeing and having the balance healthy life style.

Many Machine Translation (MT) systems are being developed world wide, especially in Japan and Europe to address this chalanges in the 21 century. The research and development of modern Sinhalese began recently. This paper discuss the similaraties of Japanese and Sinhalese and discusses the metholody used on MT process, and the problems encountered and present status and future plans.


At-speed testing with functional speed clocks is often done using On-Product Clock Generation (OPCG). When test compression logic is also embedded within the circuit's DFT architecture, the loading of the OPCG programming bits can impact test compression results. We present an approach to the use of OPCG that enables high-speed testing and is compatible with test compression. It also enables the use of tests that pulse multiple domains to further reduce test time and data volume. It also supports generation of inter-domain and static ATPG tests. We present results on four designs; one design shows an over 35% reduction in patterns due to use of multiple clock domains per test. An additional 10+% savings is possible using side-scan to load the OPCG programming registers.


The project goal is to provide an integrative approach for the rational and personalised design of drug carriers in cancer, using the mechanical properties of cells and particles as the main principle for drug targeting— based on cell uptake. Our unique approach uses physical differences between normal and cancer cells that can define the capacity of a given particle to be engulfed by a deformable cell in order to promote specificity of therapy. In the project, we aim to establish a correlation between cancer cell deformability, malignancy and 'phagocytosis'. The project includes advanced technologies of microfluidics, nanotechnology and theoretical physical model.


Aim: The aim of this work is to assess the organizational risks of H. pylori eradication therapy and the control methods of antibiotic resistance by a clinico-pharmacological analysis of the purchases structure in Russian state-funded medical facilities. Materials and methods: A legal framework in the fields of purchases of products, works, services for state and municipal needs, open contract bids, schedule and annual procurement plans for 2017, the Ministry of Health of Russian Federation statistical materials were explored. Results: According to Russian and international guidelines, current purchases of products, works, services are mainly related to a primary H. pylori identification not its eradication control. "Quasi-reference" H. pylori diagnostic methods with lower sensitivity in comparison to reference ones and extremely low specificity are relatively popular. Conclusion: Information related to the structure of products, works and services purchases for H. pylori diagnostics on the Federal Acts No. 44 and 223 united information web-system (http://zakupki.gov.ru) shows no rational assessment of effective eradication therapy while H. pylori is recognized as a microorganism with a high potential for adverse drug reactions and drug-to-drug adverse interactions development. WHO made H. pylori a priority pathogen for antibiotics research and development.

Consolidation in the banking industry has caused concern about the survival of small banks. Empirical evidence, however, shows that small banks are performing better than larger banks in terms of loan growth and profitability. This paper investigates the determinants of such unexpected superior performance; in particular we posit that peculiarities of small banks, like their ability to lever on relationship lending, are good explanatory variables of their recent loan growth.


This study aims to examine the effect of BPJS (Social Insurance Administration Organization) receivable management, and the inaction of BPJS (Social Insurance Administration Organization) claim repayment, on private hospitals funds flow in Surakarta.

The clinical effect of X-rays, as well as some of their effects on the morphology of certain tissues, is well known. Their biochemical effects, however, have not been studied extensively. Thomson and co-workers (1) have shown that in rats the desoxyribonucleic acid (DNA) and to a smaller extent the ribonucleic acid (RNA) content of the thymus decreases on exposure to 800 R of gamma rays. It has also been established (2) that following irradiation of 310—620 R of gamma rays, the concentration of RNA and that of DNA in the bone marrow of rabbits decreases markedly. Lutwak-Mann (3) observed the decrease of the phosphorus content of the nucleic acid in the bone marrow of rats. Holló and Zlatarov (4) noted a pronounced diminution of the total phosphorus content of the epidermis of rats following contact X-ray irradiation. Investigators have examined the changes due to irradiation with contact X-rays in the phosphorus content of the DNA, RNA and lipoid fractions of the epidermis. The hair of white rats, of both sexes, weighing 80—120 gm. was plucked on both sides of the animals in an area of 3 x 6 cm. On the 9th to 11th day following the plucking, a dose of 3000 R was applied to one side, in two fields, with a Philips contact apparatus (2 mA, 50 kV and a focal distance of 20 mm) without filtration. The epidermis of the other side of the animal was used as control. The plucking was carried out prior to the start of the experiment in order that the hair on the areas used for the experiment would be approximately at the same stage of development. At the time of the X-ray irradiation the new hairs had not yet reached the surface of the skin, or were only barely visible. The animals in which the hairs were a few mm. long were not used for the experiment. Observations were made on the 2nd, 3rd, 4th, 5th and 7th day. By this time the hair on the areas of the skin treated with X-rays, as well as on that of the controls, were long enough to be plucked out with pincers. On the day of the examination the animals were sacrificed and the hairs on the areas of the skin used for the experiment removed. After the 3rd day following irradiation, the removal of the hairs became progressively easier. From the 5th day on, the epidermis, which was swollen because of irradiation, could be easily injured and had to be treated with great care. The epidermis was separated from the connective tissue by means of a N solution of potassium hydroxide (KOH) using the method of Holló and Zlatarov (4, 5). The analysis of the substance obtained in this manner was carried out by combining the methods described by Schmidt and Thannhauser (6) and Schneider (7), and as described by Holló and Zlatarov (8) in their work with the mouse


Protein–protein and protein–carbohydrate interactions as a means to target the cell surface for therapeutic applications have been extensively investigated. However, carbohydrate–carbohydrate interactions (CCIs) have largely been overlooked. Here, we investigate the concept of CCI‐mediated drug delivery. Lactose‐functionalized β‐cyclodextrin (L‐β‐CD) hosting doxorubicin (Dox) was evaluated for site‐specific delivery to cancer cells via interaction with GM3, a cell‐surface carbohydrate. The host–guest complex was evaluated in B16 melanoma cells, which express exceptionally high levels of GM3, and acute monocytic leukemia (THP‐1) and mouse fibroblast (NIH‐3T3) cells, which lack GM3 on the cell surface. Doxorubicin (Dox) was delivered more efficiently into B16 cells compared with NIH‐3T3 and THP‐1 cells. In B16 cells pretreated with sialidase or sodium periodate, thus preventing CCI formation, drug uptake was significantly decreased. Taken together, the results of these studies strongly support CCI‐mediated uptake via the GM3–lactose interaction as the mechanism of controlled drug delivery.


Due to decoupled energy and power, the aqueous organic redox flow battery (AORFB) represents a promising energy storage technology that stores energy in redox‐active organic compounds dissolved in aqueous electrolytes. The organic compounds are composed of earth‐abundant elements and are therefore potentially cost‐effective. Their structures are diverse and highly tunable, rendering it possible to regulate the redox potential, water solubility, and cycling lifespan. Therefore, the adoption of redox‐active organics greatly expands the space for enabling exceeding performance merits compared to their inorganic counterparts. Herein, this work reviews the molecular design and engineering scheme of organic electrolytes, focusing exclusively on pH‐neutral AORFB that uses non‐corrosive and nonflammable pH‐neutral aqueous electrolytes with inexpensive inorganic salts as supporting electrolytes and features high safety, low corrosivity, low cost, and environmental benignity. Some comments on the present challenges and prospects of this ascendant domain are also presented.

ABSTRACT UN peacekeeping operations have introduced new data-based systems such as the Situational Awareness Geospatial Enterprise (SAGE) and the Comprehensive Planning and Performance Assessment System (CPAS). Simultaneously, UN leadership has repeatedly made the case that more women in peacekeeping will make peacekeeping more effective. We argue and show that these initiatives while occurring concurrently have been separate and that there is a lack of gender mainstreaming in the data-based approaches. We contend that this has negative consequences: It produces incomplete data regarding threats and needs of local beneficiaries and peacekeepers, it impedes performance assessment, and it leaves inefficiencies unaddressed.


Systematic neutron scattering measurements have been performed on the Sr-doped La(2-x)Sr(x) CuO4 to study the doping dependence of spatially modulated dynamical spin correlations or so-called incommensurate spin fluctuations. The modulated spin correlations appears beyond x approx. 0.05 which is close to the lower boundary of the superconducting phase. First evidence was observed for the linear relation between the degree of spatial modulation or the incommensurability delta(x) and the maximum Tc at x. We present a universal curve for delta(x) by adding data from other La2CuO4 systems such as oxygen-doped superconductors, oxygen-reduced or Zn-substituted non-superconductors and La(1.6-x)Nd(0.4)Sr(x)CuO4.


This paper describes the design and development of new software for spectral analysis, editing and resynthesis. Analysis is accomplished using a variation of the traditional McAulay-Quatieri technique of peak interpolation and partial tracking. Linear prediction of the partial amplitudes and frequencies is used to determine the best continuations for sinusoidal tracks. A high performance user interface supports flexible selection and immediate manipulation of analysis data, cut and paste, and unlimited undo/redo. Hundreds of simultaneous partials can be synthesized in real-time and documents may contain thousands of individual partials dispersed in time without degrading performance. A variety of standard file formats are supported for the import and export of analysis data.

This paper presents a redistribution loss allocation method for improving Z-Bus loss allocation. In the pool model it redistributes the loss fractions of generation buses assigned in Z-bus loss allocation to the load buses. As a result, the proposed redistribution method overcomes the main drawback of the Z-bus allocation-no flexibility to select the bus where the loss should be assigned. In most instances, the redistribution method can eliminate the negative loss allocation. Under the bilateral model, the redistribution method reallocates the generation loss fractions to their own bilateral contracts. During this procedure, the pool transactions under the bilateral model are considered. By applying this method in bilateral model, the reflections of network topology and network relationship between the both sides of bilateral contracts are taken into account.

The effect of Cryptococcus luteolus (strain 228) heteropolysaccharide on heterotopic bone marrow organ formation was studied. Heteropolysaccharide (Hp) injections were initiated on the next day after bone marrow transplantation and were performed weekly for 30 days. This resulted in the increase in both the cellularity and the weight of the ossicle. The injections performed twice weekly produced the decrease of cellularity while ossicle weight did not change. Higher dose of Hp produced no changes in heterotopic bone marrow organ. Hp injections to donor mice did not result in any changes in heterotopic organ in bone marrow recipients. Thus, this kind of Hp was capable both of stimulating and inhibiting heterotopic bone marrow organ formation in relation to the dose and scheme of administration.


An apparatus that records the amount of ..beta..-active gas (vapor) diffusing through the specimen by means of ionization chambers, which provide recording of Q = f(t) by a pen recorder, is described. Measurements have to be made on the diffusion characteristics of films: diffusion coefficient, permeability, and solubility. These involve determining the amount of gas or vapor Q passing through the specimen as a function of time t for given values of the area, thickness, and gas concentration. To record Q = f(t) one can use a manometer method, but for radioactive gases one can measure Q with internal counters, although these are complex to use, and also it is difficult to automate the recording Q = f(t) on account of the digital nature of the signal.

The high-pressure phase of pyrope (Mg 3 Al 2 Si 3 O 12 ) was investigated using a laser heated diamond anvil cell in the pressure range of 20-60 GPa. The quenched samples were examined by X ray diffraction technique using synchrotron radiation and scanning electron microscopy with energy dispersive X ray analyzer (SEM-EDX). These analyses revealed that the dissociation of pyrope into a perovskite phase and a corundum structured phase starts at about 25 GPa and these two phases persist up to the highest pressure investigated. The single phase of perovskite isochemical with pyrope was not formed in the experimental conditions. The Al 2 O 3 content of the perovskite structure was about 18 mol% at 45 GPa. Our study demonstrates that the post-garnet phase in the pyrope composition is a mixture of an aluminous magnesian perovskite with the orthorhombic symmetry and an aluminous phase with the corundum structure, which is consistent with the result of multianvil experiments reported by Irifune et al. However, the chemical compositions of two phases and their pressure dependencies are different from that of Irifune et al. and the transition pressure to a perovskite isochemical with pyrope is possibly much higher than that estimated by them.


SNCF tests embrace consolidation, chemical injection and vibratory stabilisation when investigating restoration of stability subsequent to maintenance work. Establishes that mechanised procedure using DGS vibratory machine obviates post-maintenance speed restrictions.


The electromagnetic-wave propagation through a medium consisting of two dielectric half-spaces with a plate in between, has been investigated. The half-spaces are isotropic with their dielectric permittivity depending only on the z coordinate. The plate is anisotropic, and the components of its dielectric permittivity tensor are also z-dependent. For the first time, the sufficient conditions allowing the transformation of the system of Maxwell's equations into two independent equations, are ascertained. For an arbitrary z-dependence of the dielectric permittivity, the plate's reflectance and transmittance coefficients are obtained, this result being a generalization of the Fresnel formulas. We have considered both determinate and random dependences of the dielectric permittivity on the z-coordinate, and the plate's full-transparency conditions are specified. For a statistically inhomogeneous plate, the conditions of its full opacity are formulated. The Faraday effect in such a medium is studied. The influence of the medium's inhomogeneity on the temporal rotation of the polarization plane of a propagating wave has been demonstrated.


Abstract Egg shell quality is a trait that is commonly measured and reported in different units. As a result, correlations between various units of measure are of real importance when comparing data measuring the same trait but reported in different units. Periodic examination of these relationships, although previously reported, are useful in determining their stability. Olsson (1934) reported a correlation of .94 between specific gravity and percent shell. A correlation of .754 between specific gravity and shell thickness was reported by Godfrey and Jaap (1949). This study was undertaken in order to further examine the relationship of various measures of egg shell quality. PROCEDURE Eggs were collected for five consecutive days from approximately 300 Single Comb White Leghorn pullets 200 days of age which originated from the Cornell Randombred population maintained at the North Central Regional Poultry Breeding Laboratory. Eggs were weighed to the nearest two-tenths gram and the specific gravity…


When one decides to design on-line educational materials, he have to bear in mind multiple dimensions, such as the non-linearity of the hypertext, the use of embedded multimedia languages and the interactivity between learners and educational tools. The Internet and the Information and Communication Technologies provide a challenge to develop all these dimensions in order to enhance web-based learning. The AFINET project (Learning of Physics through the Internet) is intended to know which transformations of a classic linear text on Physics education need to be done to develop hypertextual materials.

In this paper, monosaccharide (glucose and fructose), disaccharide (sucrose and trehalose), trisaccharide (raffinose) and tetrasaccharide (stachyose) were selected as the research objects and the glycosyl polyaldehydes and glycosyl polyuronic acid anti-wrinkle finishing agents were prepared via selective oxidation. The anti-wrinkle properties of their finished fabrics were analyzed, the molecular radius, the number of reactive groups, the number of reaction sites and the number of rotatable bonds of the finishing agent were calculated to evaluate its diffusion rate and crosslinking characteristics inside the cellulose. Through molecular simulation, the number of possible conformations of the anti-wrinkle finishing agent with the single cross-linked state was calculated, and the distance between different cross-linking points was measured, and the relationship between the effective cross-linking radius and the anti-wrinkle performance was studied. The results showed that trehalose polyaldehydes, raffinose polyaldehydes, trehalose polyuronic acid, and raffinose polyuronic acid finished fabrics had an excellent anti-wrinkle property, the strength retention rates of the fabrics were all above 68%, and the whiteness index was above 70. The smaller the molecular radius was, the easier the finishing agent was to diffuse into the cellulose. The most suitable crosslinking radius of glycosyl finishing agent was 3.5–6.0 Å.


This rticle examines the tactics employed by the Peaceful Streets Project (PSP), a police accountability organization in Austin, Texas. Specifically, it explores the activists' reasons for addressing police accountability and why the majority of the members are men. Drawing on analysis of in-depth interviews, participant observation, and organizational materials, the findings suggest that collective action and contentious politics play roles in the activists' decisions to address police accountability and their measures for doing so. This study adds to the social movement literature by examining how collective action and contentious politics aid in the tactics for addressing police accountability and the racialized, classed, and gendered dynamics of member participation.


Nineteenth-century American women's patchwork-quilt fiction sought to redefine the concept of « brotherhood, established in Winthrop's « city upon a hill, by providing an inclusive and matriarchal model for the communal experiment that was America. Patchwork-quilt fiction, from such domestic writers as Susan Warner to local colorists like Sarah Orne Jewett, combines realistic detail with women's metaphors like the hearth, home, kitchen, garden, and quilt, to express feminine ideas about community.


Toby Monsod's paper on the housing needs of urban squatters challenges the current orthodoxy of Filipino housing programs. She concludes that the housing choices of squatters do not consistently favor homeownership, and that factors other than tenure (such as location and dwelling type) also inouence their decisions. Drawing on a national survey data set with nearly 7,000 observations covering the Greater Metro Manila region, Monsod uses a discrete choice framework to estimate housing choice of urban squatters. She subsequently runs simulations of ave housing policy regimes to test the responsiveness of different groups of urban squatters to these policies.


The size controlled colloidal gold nanoparticles were prepared by sodium citrate photochemical system. The size and morphology of the gold nanoparticles were characterized by TEM and UV-Vis spectroscopy. nanoAu/C catalysts were obtained by loading the gold nanoparticles. The catalysts were used for the catalytic oxidation reaction of glyoxal and glucose in liquid phase. The research results showed that the catalysts had higher catalytic activity, and this preparation method is successful.


The metropolitan zone of San Luis Potosi (ZMSLP) is strategically located between the most crowded cities of Mexico: the nation's capital (Mexico City), Guadalajara and Monterrey. Furthermore, it is part of the migration route of people comingfrom Central American countries to the United States. This situation has caused a vertiginous industrial/services infrastructure development during the last twenty years. In order to know the susceptibility to urban growth, a logistic regression analysis was carried out. Urban growth was determined using multidate-Landrat 5 tm imagery by integrating geospatial data layers. From the variables reviewed, the distance of the industrial zone, the elevation and the land cost have an important statistical behavior. Susceptibility zones to urban growth are presented as a tool for territorial planning at regional level. The statistical model was successfully validated using a cross-validation 10-fold algorithm.


Now that some mines are running out of the resources and the newly-disc overed mine reserves can not meet the demand of the market,the key of solving th e problem lies in"commercialization of reserves" and a perfect market mechanism. This paper suggests establishing a national reserves storehouse of mineral prod ucts and, in the course of setting up the storehouse,solving such problems as re serves prices, determination of quantity and quality, and classification and gra ding of reserves.


In schools, band is often seen as a class where students and teachers can be creative. But is this true? Many schools use a traditional band model, which may not allow space for creative activities. This article, inspired by the Music Educators Journal March 2017 special focus on teaching for musical creativity, examines and critiques the traditional model of school band with respect to the space offered for creative music experiences and offers ideas for band directors of how to structure their programs to help foster more creative musical activities.


Unlike the designs of common zoom lenses in literature, mobilephone applications demand an extremely short total track length (TTL), less around 10 mm. This short TTL request makes the zoom lens design of mobile phones unique. Also in viewing the cost advantage of CMOS sensor, we explore the mobilephone camera zoom lens with typical CMOS sensor format by global explorer (GE) optimization as well as the fundamental limitations. The basic lens forms for initial designs are deduced. Physically different merit functions have been developed to investigate how the best performance could be achieved. Furthermore, we also identify the improvements that could be achieved by GE optimization.

For the tenth anniversary of the launch of the Journal of Decision Systems in 1992, I asked to the first Editorial Committee members to freely express their views on the DSS field in a special issue of the journal. I received eight papers among which six were suitable for this issue. These papers broadly reflect the current research work of their authors. All these authors make allegiance to the DSS community, but as can be seen, have very heterogeneous concerns. I have purposefully avoided interfering with this variety because I think that DSSs are really diverse systems with the common aim to help decision makers whatever the method used. It does not matter that a cat be black or white provided it catches mice!

The degradability of ground hardwood by thermophilic anaerobic bacteria (Clostridium thermocellum with or without Thermoanaerobacter strain B6A) was greatly enhanced by pretreatment of the substrate with supercritical ammonia. Relative to C. thermocellum monocultures, cocultures of C. thermocellum and Thermoanaerobacter strain B6A degraded 1.5-fold more pretreated soft maple but produced 2- to 5-fold more fermentation endproducts because Thermoanaerobacter sp. removed reducing sugars produced by C. thermocellum during the fermentation. Dry weight losses were not totally accounted for in end products, due to formation of partially degraded material (<0.4 μm diameter wood particles) during the fermentation. One pretreated hardwood, Southern red oak, was fermented poorly because it released soluble inhibitors at the 60°C incubation temperature. Considerable (6- to 11-fold) increases in substrate degradability were also noted for supercritical ammonia-pretreated wood materials fermented in an in vitro rumen digestibility assay. Degradation of pretreated softwoods by either thermophilic or mesophilic fermentation was not measurable under the conditions tested.


With a focus on the archives of Gemma Galgani (1878–1903), lay Italian Catholic mystic, stigmatic, and first saint of the twentieth century, the current article highlights the ways in which Gemma cultivated relationships with the hierarchy, specifically through writing, which challenged the 'traditional,' clerically approved models of late nineteenth-century Catholic sanctity. With attention to Gemma's writing, a saint who has otherwise been portrayed by her hagiographer as fitting neatly into the strictures of Italian Catholicism of her time, we see rhetoric that contests the assumption that submission is a necessary component of 'piety.' Attending to Gemma's letters sent to her spiritual advisor, the current study underscores the ways in which we may understand Gemma as more than the quiet, humble, and wounded body for which she has been canonized. Gemma as author, as writing body, as I will show, weaves for herself an alternative system of agency that co-exists with – while at the same time reimagines – the hierarchy of the Catholic Church.

Aiming at the problem that the noise signal detection of transformer is easily interfered by the external environment, three anti-interference test methods are proposed based on the time-frequency characteristics of the typical insects, birds, frogs and vehicle noise around the transformer, including wavelet packet spectral subtraction, short-time window method and filter method. The effectiveness of the algorithm is verified by field measurement. The results show that both wavelet packet spectral subtraction method and filter method can achieve better suppression effect for different interference sources, and their performance is generally better than that of short-time window method. The result has important reference significance for improving the measurement accuracy of transformer noise in complex environment.


1. Solution: The covariance matrix of the parameter vector, after selecting the first two training examples, x 1 and x 2 , is given by To minimise the trace, the second term should be as small as possible. Since x 1 x 2 lies between 1 and −1 in the input region of interest, the minimum occurs when x 1 x 2 = −1. Thus, x 1 and x 2 take the extreme values 1 and −1. 2. Solution: After using two training examples, output variance at a test point x 0 is given by output variance(x 0) = 1 x 0 C 1 x 0 = 1 4 1 x 0 2 0 0 2 1 x 0 = 1 2 (1 + x 2 0).


A new chlorine dioxide-iodine-acetylacetone chemical oscillatory reaction has been studied by UV-vis spectrophotometric method. The initial concentrations of acetylacetone, chlorine dioxide, iodine, sulfuric acid, and the pH value influence the oscillation observed at wavelength of 575 nm for the starch-triiodide complex. There is a pre-oscillatory or induction stage and the amplitude and the number of oscillations depend on the initial concentration of the reactants. Equations for the starch-triiodide complex reaction rate change with reaction time and the initial concentrations in the oscillation stage have been obtained. The induction time decreases linearly with the initial concentration of acetylacetone. The oscillation reaction can be accelerated by increasing the reaction temperature. The apparent activation energies at the induction stage and the oscillation stage are 24.94 kJ/mol and 7.38 kJ/mol, respectively. Generating the enol isomer by keto-enol tautomerism is an important step to constrain the time of induction period.


Abstract:This field report describes the Antipode Cities Project, which aimed to connect Earth's most geographically distant cities with collective cartographies made by local children. For the project, the author and art gallery staff conducted a series of map-making workshops on opposite sides of the world with children ranging from five to eight years old. The children's cartographies showcased a sort of natural urbanism, a trait that could be called "primal urbanism"—an innate perception of the city as a place that could be transformed by projects to alter its shape and form. The Antipode Cities Project, with the aid of different Chinese and Argentinean institutions, organized a research field trip and a series of workshops to compare Qingdao, China and Buenos Aires, Argentina—two cities that are at the exact geographical antipode from each other. This field report describes the conducted activities, perspectives and outcomes along with considerations about the pedagogy behind the concept of antipode cities from children's perspectives.
