The archive of the Solovetsky Stavropegial Monastery is a unique monument of Russian medieval writing and a valuable source on the history of monastic land ownership in the 15th – 17th centuries. The Archaeographic Commis-sion and the Holy Synod saved the monastery`s archive in 1917, ensured its preservation and secured scholars' ac-cess to the documents. The article focuses on Professor Boris Dmitrievich Grekov (1882–1953) and his contribution to the evacuation of the Solovetsky archive from Arkhangelsk to Perm along with its preservation from destruction. Grekov was the founder of the Department of Russian History at the Perm University, a member of the USSR Acad-emy of Sciences, and was honored by getting the Stalin award. Grekov's personal files deposited in the State Ar-chives of the Perm Region are the main source for the research. The documents help better understand the scientific and pedagogic work of this outstanding scholar in Perm. In addition to Grekov's contribution, the article highlights the role of the Perm diocese of the Russian Orthodox Church and its head, the archbishop of Perm and Kungur An-dronik (Nikolsky), in rescuing the documents of the Solovetsky monastery and delivering them to Perm. The author introduces new information into the scientific circulation that sheds the light on the activity of the scientific corpora-tion of the Perm University during the years of the revolution and the Civil War. The author concludes that the preservation of the unique monument of medieval Russian history (the archive of the Solovetsky Monastery) was a joint effort of the Perm University and Perm Diocese of the Russian Orthodox Church. The leading role in this rescue goes to the scholars of the Perm University and personally to Boris Grekov

Summary We previously demonstrated abnormal Ca2+ transport by microsomes in platelets from a grey platelet syndrome patient. Here, we investigated the platelet Ca2+ ATPases that mediate this transport, as well as its possible regulation by rap 1 protein. We showed that grey platelet syndrome platelets expressed the same two distinct Ca2+ ATPases as those recently described in normal platelets; the 100 kD SERCA2‐b isoform (Sarco/Endoplasmic Reticulum Ca2+ATPase) and a new 97 kD SERCA isoform. The two Ca2+ ATPases formed similar amounts of transient phosphorylated intermediates. The expression of these two Ca2+ ATPases was compared by Western blotting using specific antibodies, which again emerged in similar amounts in normal and grey platelet syndrome platelets. As regards the protein phosphorylated by cAMP, it was found to be identical to rap 1 protein when it was immunoprecipitated with an antibody raised against a synthetic peptide specific for rap 1 protein. Although the expression of rap 1 protein was similar in membranes isolated from grey platelet syndrome and normal platelets, its exogenous phosphorylation by cAMP was abnormal, with a concentration (10 μg/ml) of the catalytic subunits of the cAMP‐dependent protein kinase (C.Sub.), as it decreased to half the control level.


V iral bronchiolitis is a common cause of respiratory failure in children. Approximately 10% to 15% of previously healthy children are likely to be admitted to an intensive care unit (ICU) if they become hospitalized by bronchiolitis, and approximately half of these children will needmechanical ventilation. Childrenwith preexisting conditions, such as congenital heart disease and chronic lung disease, and children who are immunocompromised are at a much greater risk of developing bronchiolitis. The viruses that cause bronchiolitis cause the small airways in the child's lungs to be obstructed; this causes them to cough and wheeze. Bronchiolitis has no definitive treatment. Although many different therapies for bronchiolitis have been identified and studied, there currently is not enough evidence to support the use of any of them, and children with bronchiolitis are often given only supportive care. Surfactant is a substance made up of proteins and lipids that is required for normal functioning of lungs. Severe bronchiolitis may also cause children to become deficient in surfactant. Surfactant has been suggested as a possible therapy for bronchiolitis as it is able tomake the alveolimore stable and helps to improvemechanical properties of lungs. Therefore, it has been suggested that administering surfactant into the lower airwaysmight help childrenwhodevelop severe bronchiolitis to recover from the diseasemore quickly.


The Paper is a discussion from a new standpoint of the data, collected by Dr. Bauer, for 15 magnetic storms. Maunder's work on the recurrence of magnetic storms at intervals equal to the rotation period of the sun suggests that storms are due to some solar agent transmitted along narrow well-defined streams, issuing from and rotating with the sun. This suggests the view that the relative time of commencement of a storm at different stations depends mainly on the orientation of the latter at the time, relative to the sun, i.e. on the local time at the station. This forms the basis of the classification in the Paper.


Background: Nurses play a crucial role in the early recognition and management of the deteriorating patient, (Odell et al 2009, Liaw et al 2011). As they are responsible for the care they provide to their patients. A part of this care is the monitoring of the patient 's vital signs such as blood pressure, pulse, respiratory rate, temperature, which are fundamental in the surveillance of health deterioration. Methods : The aim of this study is to discover what factors influence how nurses assess patient acuity and their response to acute deterioration. influence how nurses assess patient acuity and their response to acute deterioration. This study will endeavour to identify factors associated with the recognition of disrupted vital sign's. In addition to this, the study will explore how nurses cognitively know or recognise acute patient deterioration.


Needs assessment is here to stay as schools wishing to apply for grants under the competitive titles of the Elementary and Secondary Education Act (ESEA) must now justify their requests. However, quality assessment data cannot be obtained in the majority of school districts nationally without federal or state budgetary allocations for local Education Agencies (LEAs) to conduct systematic needs assessments. State combination not selected by the participating schools, option 4: a local adaptation the affective or secondary areas with ESEA Title I money. There is an obvious credibility gap here. On 'one hand, there is the demand for needs assessment. On the other hand; there is the powerful external influence on local perceptions of needs resulting from requirements for programs under categorical federal and state funding. Because of legislation, special funding, and other external pressures, schools may.find it difficult to take a new look at their goals and their programs. Since it is obvious that federal and state agencies will continue to demand needs assessments, these agencies must also be realistic enough to provide the necessary assistance to insure that locally determined priority needs will be met. Changes in the ESEA Title I statute, guidelines, and funding must be made in order-to achieve these ends. (Author/MV)

Irreversibility and uncertainty increase the user cost of capital which tends to reduce the capital stock. Working in the opposite direction is a hangover e!ect, which arises because irreversibility prevents the "rm from selling capital even when the marginal revenue product of capital is low. Neither the user cost e!ect nor the hangover e!ect dominates globally, so that irreversibility may increase or decrease capital accumulation. Furthermore, an increase in uncertainty can either increase or decrease the long-run capital stock under irreversibility relative to that under reversibility. Other e!ects that we consider, however, have unambiguous e!ects on long-run capital accumulation. ( 1999 Published by Elsevier Science B.V.

This article presents the results of two semantic differential studies that focus on cultural values and modernization, which were carried out in Kelantan, Malaysia, first in 1969 and the second in 2001.The results of these quantitative psychological anthropology studies, complimented by more than 3 years of traditional fieldwork, provide a finely textured means to assess both the direction and the degree of sociocultural change in what has been a very traditional, conservative, Islamic, peasant community, but which now, with some notable exceptions, appears to be rapidly modernizing. Utilizing both quantitative and qualitative data resulting from our investigation, the authors discuss the continuing dominance of Islam in the conceptual and value system of virtually all Kelantanese Malays and some of its consequences for peace in the country and throughout the region.

Research communities have made significant efforts to derive dynamic equivalent models (DEM) for wind farms due to the high penetration of wind energy. The whole development can be divided into two categorical approaches: aggregated DEM and multi-machine pre-clustered DEM. However, with the stochastic characteristics of wind speeds and different crowbar activation patterns inside the wind farm resulted from different fault types, conventional DEMs may not be accurate for all kinds of faults, therefor are not suitable for post-fault analysis. This paper focuses on developing a DEM for LVRT studies. Firstly, a two-level clustering algorithm was proposed to build dynamic clusters based on the crowbar triggering waveforms and the grouping indicators' data, where Gaussian density distance clustering algorithm was applied. Then the established aggregated DEM was updated according to the previous clustering results. Different fault scenarios were tested. Compared with conventional methods, the simulation results showed that the proposed method could be more accurate to represent the dynamic response of the wind farm when there were several different triggering patterns from crowbar systems for post fault analysis.


By now, Wikis have been established as valuable tools in companies as well as in academic environments. Content in wiki-based articles can be easily created, managed and utilized by communities of different sizes. Also, the formal representation of knowledge, using semantic web technologies, for example, has gained momentum. Semantic Wikis offer the potential to combine both in a Social Semantic Web. On one hand, they enable users to collaboratively create articles, just like with a conventional Wiki, on the other they also allow them to collaboratively gather facts in a formal language. This article provides an overview about the currently available systems and shows some common use cases.


Rock outcrops provide unusual environmental conditions, often being the habitats of disjunct populations or rare species. A large rock plate on Mt Direction, within the Meehan Range, southeastern Tasmania, supports an open-heath of unusual floristic composition, and contains the only known population of Ozothamnus reflexifolius Leeson & Rozefelds. Four floristic communities occur on and around the plate, forming a sequence from the open-heath on the plate itself to tall woodland with a dense understorey of small trees where rock and bare ground cover are low. Patterns of moisture availability, related to soil depth, aspect, slope and topographic position seem to best explain the floristic, structural and species richness patterns in the area.


Multi-channel LED drivers are required in many applications, such as display backlighting, indoor lighting and street lighting. The LED driver should have the capability of providing multiple constant current source regardless to the LED forward voltage variations. Moreover, how to achieve current sharing between multiple LED channels is also challengeable in these applications. In this paper, a multi-channel constant current (MC3) LLC resonant LED driver is proposed. The LLC converter is controlled to operate as a constant current mode LED driver. By employing the multiple transformer structure, one single-stage driver can drive multiple LED channels, simplifying the driving scheme and circuit complexity. A DC block capacitor is utilized to balance the currents between two LED channels driven by the same transformer. After considering LED's i-v characteristic, the LLC current gain characteristic is proposed and derived to describe a LLC converter with current-controlled output. Instead of constant resistive load considered in LLC voltage gain characteristic derivation, a non-linear LED load is modeled and used in AC equivalent circuit to derive LLC current gain characteristic. A design methodology for MC3 LLC LED driver has been developed based on the proposed LLC current gain characteristic. A 100kHz, 200W, 4-channel MC3 LLC LED driver is designed and simulated to verify the proposed circuit and design method.


The Bowed plates weld device (BPWD) is a new type of rail weld reinforcement device, which has been widely applied in heavy haul railway lines in China. It changes the service state and vibration characteristics of a weld. In order to explore the BPWD vibration influence on the track, static, and dynamic on-site tests were carried out on a heavy haul line. The vibration influence and spectrum characteristics of the track between BPWD and unplated weld (UW) was compared. At the same time, a 3D coupling model of heavy haul train-rail weld was established and optimization of service performance of the BPWD was carried out. The results showed that the average acceleration of rail, sleeper and ballast at the BPWDwere 52.7%, 43.5%, and 50.2% lower than that of UW. In comparison with UW, peak value of the periodic frequency spectrum and dominant frequency distribution in the BPWD track structure could be effectively reduced from rails to ballast. Length of 0.8 m for plate was found to be optimum in order to reduce the rail stress effectively. The material of the insulating interlayer should preferably be nylon.

N-3 fatty acids are reportedly effective for asthma. In addition, spa therapy has been reported to be effective for patients with asthma. In the present study, the effects of spa therapy combined with perilla seed oil- rich diet (rich in n-3 fatty acid)were examined on asthma. A total of 14 asthmatic patients had a complex spa therapy and consumed a perilla seed oil- rich diet - rich in a -linolenic acid (alpha-LNA) for 8 weeks. Generation of leukotriene (LT) C4 by leucocytes, respiratory function were analyzed. The generation of LTC4 by leucocytes decreased significantly for 2, 4 and 8 weeks (P<O.05). Peak expiratory flow (PEF) values increased significantly for 2,4, 6 and 8 weeks (P<O.05). The values of ventilatory parameters [forced vital capacity (FVC) , forced expiratory volume in one second (FEV(1)) forced expiratory flow after
25% of expired FVC (FEF(25)), forced expiratory flow after 75% of expired FVC (FEF (75)) • mean expiratory flow during the middle half of the FVC (FEF(25-75)) ] revealed a significant increase after 4 and 8 weeks of the modified diet (P<O.05). The results suggest that spa therapy combined with a perilla seed oil- rich diet are effective in the treatment of asthma in terms of its ability to suppress LTC4 generation by leucocytes, and in inducing an improvement of pulmonary function.


Women violence is a widespread problem that affects millions of women and girls across the world. The gender-based violence that threatens the well-being, dignity, and rights of women extends across social, cultural, economic, and regional boundaries. Women in all countries, irrespective of status, class, age, caste, or religion, experience violence once in a lifetime. However, specific groups of women suffering from various forms of discrimination, such as women with disabilities, migrant women, and lesbian, bisexual, and transgender women, are particularly vulnerable to violence. In this chapter, the author presents brief knowledge about the different type of violence against the women and also describe laws, policies, and social work which is used for the safety of the women. The theoretical framework is used to describe the remedies against violence and also help to provide love, safety, security, and shelter for every individual woman.

Scientific research management is of vital significance in higher vocational colleges.It is essential to do research on regulating and innovating relevant management behaviors so as to improve their present situation in vocational and technical colleges.


There has been considerable progress in electrostatically emptying, and refilling, quantum dots with individual electrons. Typically the quantum dot is defined by electrostatic gates on a GaAs∕AlyGa1−yAs modulation-doped heterostructure. We report the filling of such a quantum dot by a single photoelectron, originating from an individual photon. The electrostatic dot can be emptied and reset in a controlled fashion before the arrival of each photon. The trapped photoelectron is detected by a point contact transistor integrated adjacent to the electrostatic potential trap. Each stored photoelectron causes a persistent negative step in the transistor channel current. Such a controllable, benign, single photoelectron detector could allow for information transfer between flying photon qubits and stored electron qubits.


A nonlinear theory is developed for electronic conduction in the presence of acoustic energy in piezoelectric semiconductors. The theory is valid for the cases of large acoustic energy and large electric field. The resulting expression is of closed form. The conductivities of acoustoelectric domains are measured. The experimental results are consistent with the theory if the domains are assumed to be composed of more than one acoustic frequency.


This study is to examine the effects of the activity constructing mathematical meaning using an economic activity tool, 'coin', on mathematical attitude and arithmetic ability. Study subjects were two 5-year-old classes (26 children each) at the public kindergarten located in Gyeonggi-do. 15 mathematical activities using 'coin' were constructed and applied to the children in experimental group twice a week for approximately 2 months, and results were drawn through a preliminary and post-tests along with the comparison group. As a result, the group that participated in the mathematical activity using an economic activity tool, 'coin', displayed significantly higher mathematical attitude and arithmetic ability than then comparison group. Such result implies that 'coin', which is essential in economic activities, can be an effective teaching-learning method in improving children's mathematical attitude and arithmetic ability.


SUMMARY A new interpretation of a polygonal pattern of ridges in the Marble Hill Dolomitic Limestone, at Ballymore, suggests that it was formed by a soft-bodied, worm-like organism.


Submitted for the GEC15 Meeting of The American Physical Society Electron-impact population transfer rates between metastable and resonance states of argon NADER SADEGHI, LTM & LIPhy, Univ. Grenoble & CNRS, France, EMILE CARBONE, EDDIE VAN VELDHUIZEN, GERRIT KROESEN, TUE, Eindhoven, Netherlands — Electron-impact population transfer between metastable and resonance 1s states of argon is studied by time resolved laser pump-probe technique in a surfatron generated argon plasma. A nanosecond laser pulse tuned to a 1s-2p or 1s-3p transition depletes one of the 1s metastable or resonance states of argon and the time variations of the densities in that state and the other three 1s states are then simultaneously monitored by laser absorption diagnostic with different cw diode lasers. Plasma parameters are: 6 mm diameter plasma tube, p=5-20 mbar, ne =1-6 x 10 19 m−3, Te =1-2 eV. At such high ne values e-impact transfers between 1s states dominates over all other loss processes, i.e. diffusion, Ar-impact transfers and radiative losses. A simple collisional-radiative model is used to deduce the transfer rates from the time evolution of the densities in the four 1s states following the pulsed laser depletion. At Te ≥1.2 eV, kij rate coefficients (in units of 1019 m3.s−1), for transfers between metastables and neighboring resonance states are k54 =1.6 and k32 =9, respectively. The population transfer with change of ion-core is weak for 1s2 to 1s5 (k25<<1) but resonance states are efficiently mixed, k24 =k42 =2. Recent quantum mechanical calculation by Zatsarinny et al seems to underestimate by factor 2 or more the corresponding cross-sections.

To find protein and peptide biomarkers in a biological sample, fractionation is usually required to reduce dynamic range and sample complexity. LC is a standard way of fractionating samples. Although it has a great resolving power, it is time consuming and is less ideal for the processing of many samples in parallel. Magnetic beads (Dynabeads) offer the opportunity of manual or automated high-throughput fractionation upstream of MS or 2D-gels. With 96-384 wells available, many samples can be run in parallel with one or several different chromatography surfaces (e.g., SAX, SCX and RPC 18). Because of high sensitivity and reproducibility, Dynabeads have become a popular choice for serum peptide profiling and for the pre-selection of samples (e.g., upstream of LC-MS).


In ATM networks, the time axis is divided into equal intervals called time slots, so most references assume that the Markov chain makes a transition from state i to state j in the boundary of time slots in view of Markov-modulated Bernoulli process (MMBP). This paper considers a more general situation, i.e., the Markov chain makes a transition from state i to state j in the boundary of frames whose length are an integral multiple of length of one time slot. Under this MMBP model, the paper develops a four-dimensional discrete-time Markov chain, and obtains results of the performance analysis of leaky bucket algorithms.


We introduce a definition of symmetry generating vector fields on manifolds which are equipped with a first-order reductive Cartan geometry. We apply this definition to a number of physically motivated examples and show that our newly introduced notion of symmetry agrees with the usual notions of symmetry of affine, Riemann-Cartan, Riemannian, and Weizenbock geometries, which are conventionally used as spacetime models. Further, we discuss the case of Cartan geometries which can be used to model observer space instead of spacetime. We show which vector fields on an observer space can be interpreted as symmetry generators of an underlying spacetime manifold, and may hence be called "spatio-temporal." We finally apply this construction to Finsler spacetimes and show that symmetry generating vector fields on a Finsler spacetime are indeed in a one-to-one correspondence with spatio-temporal vector fields on its observer space.


In this paper, we define the space of Computer-Supported Coordinated Care (CSCC), an approach that focuses on using technology to aid the entire community of people who support an elder who lives at home. We conducted interviews with people involved in the care of elders to identify their needs. We subsequently conducted an in-situ evaluation of a prototype technology to study how a CSCC system may help satisfy these needs. Based on the results, we identify challenges faced by the people who provide elders with care and offer guidelines for designers of coordinated care technologies.


Dual trigger protocol using a combination of GnRH agonist and hCG for final oocyte maturation has been shown to minimize ovarian hyperstimulation syndrome (OHSS) risk without compromising fresh embryo transfer outcomes. Therefore, we sought to determine if any cycle characteristics were associated with predictive of pregnancy outcomes in fresh cycles that utilized this protocol for in-vitro fertilization. In this retrospective cohort study, a total of 291 patients who underwent the dual trigger protocol and had a fresh embryo transfer 5 days after oocyte retrieval were included from January 2013 to December 2017. A clinical pregnancy and live birth rate was 67% and 60.1%, respectively. The cohort achieving clinical pregnancy had significantly lower age and a higher number of embryos cryopreserved. After stratifying for number of oocytes retrieved, 74% patients had <30 oocytes and 26% had ≤ 30 oocytes, there was no difference in clinical pregnancy rates (66.8% vs 69.2%) nor live birth rates (60.0% vs 60.5%). Logistic regression analysis identified number of embryos cryopreserved as the only parameter to predict clinical pregnancy, with an odds ratio of 1.079. There were no cases of OHSS in patients that underwent a fresh embryo transfer. This data supports the use of dual trigger to both minimize ovarian hyperstimulation risk as well as obtain excellent pregnancy rates in the fresh cycle.


This article describes the development of convection through a series of stable layers on 20 July 2004 during the pilot project of the Convective Storm Initiation Project (CSIP). Convective clouds developed in south central England as a result of diurnal heating. They formed near the south coast and grew gradually as they moved northwards, eventually producing light precipitation. Several stable layers and associated dry layers (or lids) were observed by sequential radiosondes launched every two hours. Most of these lids were also detected by the Chilbolton L‐band radar and with a wind profiler as prominent layers of Bragg echo. One particular lid at 820 mb (1.7 km) inhibited the early development of the convection for about an hour, delaying the production of precipitation. The uppermost lid at 650 mb stopped all convection from intensifying in the CSIP domain.

Propionic acids labelled either with 14C in positions 1, 2, or 3, or with 14C in position 1 and 3H in position 3 have been used as precursors in biosynthesis of rifamycins by Streptomyces mediterranei. The resulting distribution of radioactivity in rifamycins S – as determined by systematic degradation – shows that 23 of the 37 carbon atoms in rifamycin S originate from propionic acid. This result and the distribution pattern of radioactivity are in agreement with those obtained recently by 13C-NMR. spectroscopy [7].

The S-methyl groups of methionin, labelled with 14C, are incorporated in rifamycins by Streptomyces mediterranei only in the methoxy group.

The consequences of these findings for the biogenesis of other ansamycins, e.g. streptovaricins, are discussed. The similarities in the constitution and configuration of ansamycins and macrolides (cf. [9]) indicate that all these microbial metabolites are formed according to the same biogenetic pattern.


Cognitive decline is recognized as a prevalent and debilitating symptom of multiple sclerosis (MS),1 with cognitive changes often occurring early in the disease course.2 Even relatively subtle cognitive decline can have substantial real-life consequences, including negative effects on employment3 and quality of life, both for people with MS and their caregivers.4 Heightened awareness of disease-related cognitive decline has motivated cognitive screenings as a key component of comprehensive care at clinical MS centers; however, increased awareness and clinical attention has also highlighted the lack of effective symptomatic treatments for cognitive deficits.5,6 Obstacles encumbering validation of effective treatments have been discussed,1 including a lack of methodologic rigor in clinical trials aiming to improve cognition.5,6


Abstract. Three cases of severely compromised fetuses are reported in which a similar FHR tracing was observed: an undulating pattern describing a "sinusoidal" shape, a frequency of 0.5—1 cpm, amplitude of 10—15 bpm, and flattened baseline varying between 60—120 bpm. This pattern appears to differ significantly from the sinusoidal pattern described previously and appears to identify an agonal or pre‐agonal fetus that nonetheless may be salvageable and, therefore, requires maximal obstetric intervention.


Fifty-two Ss solved six conjunctive concept attainment problems. All problems had 2 relevant and 5 irrelevant attributes which were presented in a 6 by 6 random replicated Latin square design. All stimulus cards were continuously in S's view. Each stimulus card choice of S was recorded. From the protocols of S's card choices a record was made of the rate at which information about the concept became available. It was found that S's potential acquisition of information was efficient early in concept attainment but decreased in efficiency as the amount of information to be retained about the concept increased.

The integrated bone implant may allow the prosthatic rehabilitation of the oral system and the consequent reestablishment of its functions. However, one must keep in mind that implants may render rehabilitation treatment impossible. Thus, starting with a diagnostic prosthesis where the professional can foresee the final outcome is a must. Such a procedure must be followed by complementary exams to evaluate the quantity and quality of both soft and bone tissue and the need for modifications in the treatment in order to attain the preestablished goals. The diagnostic prosthesis should work as a surgical guide, helping to optimize the final outcomes by respecting the position, number and inclination of the implants. Oral rehabilitations through implants, from the simplest to the most complex, involves a close relationship between the many odontological specialties involved in the process. Descriptors: Prostheses and implants; dental implants.


In-network data aggregation in wireless sensor networks (WSNs) is a technique aimed at reducing the communication overhead—sensed data are combined into partial results at intermediate nodes during message routing. However, in the above technique, some sensor nodes need to send their individual sensed values to an aggregator node, empowered with the capability to decrypt the received data to perform a partial aggregation. This scenario raises privacy concerns in applications like personal health care and the military surveillance. A few other solutions exist where the data are not disclosed to the aggregator (e.g., using privacy homomorphism (PH)), but these solutions are not robust to node or communication failure.

The contributions of this paper are two-fold: first, we design a private data aggregation protocol that does not leak individual sensed values during the data aggregation process. In particular, neither the base station (BS) nor the other nodes are able to compromise the privacy of an individual node's sensed value. Second, the proposed protocol is robust to data-loss; if there is a node-failure or communication failure, the protocol is still able to compute the aggregate and to report to the base station the number of nodes that participated in the aggregation. To the best of our knowledge, our scheme is the first one that efficiently addresses the above issues all at once. Copyright © 2009 John Wiley & Sons, Ltd.


Broadband marine seismic data is evolving as the new standard in petroleum geoscience. Much of the dialogue to date has been focused on the seismic acquisition systems and deghosting aspects of this technology. The first requirement of any broadband project should be to "do not harm." This is especially true in the acquisition arena, since the penalty for deficient data is significant. A reasonable objective would be to demonstrate equal, or better, data quality than conventional "high-resolution" shallow-tow surveys, increased operational efficiency, and overall improved signal/noise compared to processing-only-based broadband solutions. It is probably not a reasonable expectation that a single acquisition system always will provide more value/cost benefit than alternative options. A simple metric for the effectiveness of any broadband technique is demonstration that better results can be achieved over more conventional processing flows. An understanding of data fidelity and signal attenuation (Q) is ess...


Several major developments in late 2002 provided U.S. water utilities with a strengthened federal framework for assessing and addressing vulnerabilities to terrorist attacks and updating emergency response plans as well as a measure of certainty in these uncertain times. Chief among them, and the focus of this article, are enactment of legislation creating the new Homeland Security Department, implementation by the US Environmental Protection Agency (USEPA) of a protocol for ensuring the security of written copies of the vulnerability assessments (VAs) that community water systems serving more than 3,300 people must submit (along with submission instructions), and further development of related tools, training, and technologies.


This study aims to determine the constraints on the Transit Time Performance at the DHL Express Service Center Karawaci. The data used are primary data and secondary data. The samples studied were 27 respondents. In this study, using 17 types of main categories (types of causative factors). The results of the factor analysis test show that of the 17 types of main categories that survive in the model and group them into 5 factors, the factors that affect the constraints on Transit Time Performance. These factors are the number of employees with a percentage of 40%, the work hours factor of employees with a percentage of 30%, the scanner performance factor with a percentage of 20% and the bonus factor with a percentage of 10%. The dominating factor is the number of employees which has a percentage of 40%. The factors that are formed are then analyzed using the Fishbone Diagram method to determine the causative factors graphically, so that the company can take preventive and corrective actions to reduce the error rate in service quality.


This article studies the anisotropic particle dispersion in a continuously forced, two-dimensional turbulent flow on a β-plane. The flow is immersed in a large-scale closed basin with free-slip walls. The anisotropy is analyzed in two sets of numerical experiments characterized by the magnitude of the imposed, time-dependent forcing (weak and strong). Both experiments exhibit typical features of zonostrophic turbulence: eddy motions that, on average, form alternating east–west circulation bands due to the β-effect. The dispersion anisotropy is investigated through three Lagrangian statistics calculated by zonal and meridional components: (i) relative dispersion between pairs of particles; (ii) dispersion ellipses; and (iii) finite-scale Lyapunov exponents (FSLE), also measured with particle pairs. In the experiment with weak forcing, the relative dispersion and dispersion ellipses show anisotropy with a zonal preference toward the west; however, the FSLE did not reveal significant anisotropy. In the experiment with strong forcing, the relative dispersion and dispersion ellipses show zonal anisotropy toward the west when the particles are far from the boundaries. As the particles reach the western wall and are redistributed to fill the domain, the anisotropy ceases. The FSLE show zonal anisotropy for a wide range of particle separations. The results are examined further by using no-slip boundary conditions and a rectangular domain geometry.


Background Multimorbidity is common in patients living in areas of high socioeconomic deprivation and is associated with poor quality of life, but the reasons behind this are not clear. Exploring the 'everyday life work' of patients may reveal important barriers to self-management and wellbeing. Objective To investigate the relationship between the management of multimorbidity and 'everyday life work' in patients living in areas of high socioeconomic deprivation in Scotland, as part of a programme of work on multimorbidity and deprivation. Design Qualitative study: individual semi-structured interviews of 14 patients (8 women and 6 men) living in deprived areas with multimorbidity, exploring how they manage. Analysis was continuous and iterative. We report the findings in relation to everyday life work. Results The in-depth analysis revealed four key themes: (i) the symbolic significance of everyday life work to evidence the work of being 'normal'; (ii) the usefulness of everyday life work in managing symptoms; (iii) the impact that mental health problems had on everyday life work; and (iv) issues around accepting help for everyday life tasks. Overall, most struggled with the amount of work required to establish a sense of normalcy in their everyday lives, especially in those with mental–physical multimorbidity. Conclusions Everyday life work is an important component of self-management in patients with multimorbidity in deprived areas, and is commonly impaired, especially in those with mental health problems. Interventions to improve self-management support for patients living with multimorbidity may benefit from an understanding of the role of everyday life work.

With the increasing availability of diachronic corpora, machine-aided identification of linguistic items that have undergone significant change is set to become an important task. This importance is heightened further if, as Hilpert and Gries (2009:386) have argued, approaching linguistic change in a data-driven manner can reveal otherwise unnoticed phenomena. Key to this endeavour is being able to tell apart relevant change from noise and random or other synchronic variation. This non-trivial task differs in important ways from the much more widely investigated comparison of linguistic features between two (usually contemporary) corpora and has to date not received the attention it should perhaps be afforded.
In this paper, a number of methods for identifying relevant change are reviewed and a procedure suggested which has not so far been documented. This new procedure is based on a simple chi-square test for goodness of fit, combined with additional parameters. Its operation is illustrated using the example of a study conducted to investigate motivation of recent and ongoing change in Multi-word Expressions (MWEs) using data taken from the 20-million word Swiss Text Corpus (STC). The STC is a corpus of 20th century written German as used in Switzerland (Bickel et al 2009). Results of the application of the proposed method indicate that the procedure yields high-quality instances of significant change in the data and is applicable to MWEs as well as a range of other linguistic items. It is able to identify instances of change with fewer arbitrary decisions and able to identify a wider range of different types of change than other suggested methods. Additionally, it shows that both the structure of the data as well as particular research interests will guide the choice of method used to identify relevant change.


Abstract
 This chapter provides information on the 3 classes of biogenic compounds that regularly occur in aquatic and agricultural ecosystems to contaminate food and water supplies, i.e. algal toxins, mycotoxins and phytotoxins. The toxicological issues associated with microbial and plant metabolism of these biogenic compounds are also discussed.


Vacancy engineering is an attractive approach to modulate the electronic structure of transition metal chalcogens. However, illustrating how anion vacancy can be engineered to tailor their electromagnetic (EM) parameters and electromagnetic wave (EMW) absorption, based on clear vacancy concentrations and/or various anion vacancies rather than semiempirical rules, is currently lacking but significantly desired. An anion‐doping‐induced vacancy engineering is pioneered, where the selective oxidation process upgrades the transformation from Co‐based precursor to S‐doped CoSe2 (System II) instead of Se‐doped CoS2 (System I) in the subsequent sulfuration/selenization, which results in vacancy level improvement and coexistence of sulfur vacancies (VS) and selenium vacancy (VSe). Thanks to the boosted dielectric polarization loss provided by the comparable coexistence of sulfur/selenium vacancies (VS/VSe = 0.52), S‐doped CoSe2 harvests a broad bandwidth of 9.25 GHz (8.75–18.00 GHz) at 2.42 mm. This feature almost simultaneously achieves 100% coverage for X‐, and Ku‐bands, outperforming all reported metal sulfides/selenides until now. This work establishes a clear correlation between vacancy concentrations/various anion vacancies and EMW dissipation ability, offering valuable insights for designing advanced EMW absorbing materials.


Objectives: To investigate the association of urinary albumin-to-creatinine ratio and the diameter of retinal vessel in population with essential hypertension in Fujian coastal area. Methods: Data was obtained from a cross-sectional survey,central retinal artery and vein equivalents (CRAE and CRVE) were measured from the avoid mydriatic digitized photographs and semi-automatic fundus analysis software, urinary albumin-to-creatinine ratio (UACR) was also measured. Results: (1) The CRAE levels in normoalbuminuria and microalbuminuria with hypertension groups significantly lower than the control group.Only the CRAE levels were significant in the three groups (all P < 0.01). (2) The CRAE levels were significantly negative correlated with systolic blood pressure,UACR,triglycerides,diastolic blood pressure,age, waist circumference, body mass index, haemoglobin A1, low-density lipoprotein cholesterol,uric acid and total cholesterol (r = −0.302, −0.286, −0.286, −0.255, −0.203, −0.195, −0.176, −0.112, −0.093, −0.073, −0.070, all P < 0.01).(3)CRAE was independently associated with UACR in the whole people and the hypertension after adjusting gender,age,diastolic blood pressure, waist circumference, low-density lipoprotein cholesterol,haemoglobin A1 and uric while it isn't in the nomal group.(4)The CRAE levels were independently associated with systolic blood pressure (&bgr; = 1.084, 95%CI = 1.011∼1.163,P = 0.024),The risk of CRAE abnormality increased in the microalbuminuria group than in normoalbuminuria group,the same results in the normoalbuminuria group and the nomal group (all P < 0.01). Conclusion: The early renal damage was concomitant with the abnormal CRAE levels in population with essential hypertension. UACR and CRAE were the target organ damage non-invasive index of early hypertension stage and assess the cardiovascular disease risk.


The standard approach for repair of type A aortic dissection includes repair or replacement of the aortic valve, the ascending aorta and the arch, alone or in combination with direct vision under hypothermic circulatory arrest. Although type A dissection usually extends into the distal thoracoabdominal aorta, the descending thoracic aorta is usually left alone. During the follow-up, surgeons will sequentially and periodically evaluate the patients looking for aneurysmal dilatation of the untreated aorta for an eventual late open surgical or endovascular repair. Surgery of the aorta continues to be a surgical challenge. Aortic disease and surgery are dynamic as new ideas are continuously brought up in terms of surgical approach, extension of repair and characterization of patients. Technology also plays an important role nowadays. Since the early days of high-por sity vascular grafts, until today where vascular grafts are being coated with albumin or collagen, results have dramatically changed in terms of control of hemorrhage and related intraoperative death. The inception of endovascular therapy seems to change the perception of patients suffering from descending thoracic aortic aneurysms and chronic dissections. Acute type B dissections are still a matter of concern regardless of the attempted therapy. Type A dissection routinely involves the aortic arch. Operation-related morbidity and mortality is still high. Some questions are still unanswered; like the need of performing complex combined resections of the arch and how to treat the descending aorta. To save the patient first has always been our major surgical standard and we believe this must always be priority in the critical decision-making process. Here we will have a quick look at evolving concepts, ideas and technologies, asking some questions for the near future.


The book "The Venerable Sergius of Radonezh" by Boris Konstantinovich was first published in Paris in 1925. A. V. Amfiteatrov-Kadashev assumed that it is "the best work of the writer, imbued with the warmth of humanism, but, at the same time, truly national, Russian in spirit". It is hard to disagree with this statement: B. K. Zaitsev not only describes the path of the Venerable Sergius of Radonezh, but also reflects a peculiar concept of the Russian sanctity. The fate Sergius of Radonezh resembles the path of Russia. The key traits of the true national character, the Russian soul merged in the image of the venerable old man. His image embodied the idea of the sanctity of the Ancient Rus' and modern Russia – inwardly and spiritually true Homeland. An attempt is made to determine the essence of this concept give a brief description to its main characteristics. This substantiates the novelty of this study. The author concludes that the image of the venerable old man Sergius of Radonezh resembled the image Rus' itself, which conveyed modesty, humbleness, purity and lightness, braveness and frankness, departure from rebel and extremes, humility and meekness, communication with God, love for the father's house and parents, inner beauty and outward humbleness, sincere faith. All of these features are inherent to the Russian soul. Although it is not easy to discern such natural spiritual wealth in oneself, it will point the right path and lead to true sanctity that was achieved by the Venerable Sergius of Radonezh and described in the book of B. K. Zaitsev.


Small and medium scale construction companies in Nigeria have many challenges such as management of construction works, employee management, competition in the construction industry and financial management of construction projects. New techniques emanating from lean thinking have helped to reduce cost during manufacturing. Continuous cost reduction or kaizen costing during the construction phase stems from kaizen, which is a sub-set of lean production. Kaizen is the Japanese word for continuous improvement, which has the proven benefits to reduce construction cost, provide quality products, increase profitability, enhance employee-employer relationship and competitiveness. The research methodology for this study involved literature review and surveys (quantitative and qualitative). The surveys involved questionnaires and semi-structured interviews. Quantitative data was obtained from one hundred and thirty-five (135) respondents in Small and medium scale construction companies in Nigeria. Eleven (11) executives of small and medium scale construction firms were interviewed. The qualitative data were be analysed using NVIVO 10, while descriptive statistics, pie charts, graphs, Kendall's W test, Spearman rho's correlation, and factor analysis were used to analyse the quantitative data. The critical success factors for kaizen costing implementation identified management function; operational efficiency; construction business and ethics; and construction cost management as the major implementation factors. The critical success factors, effective post-contract cost controlling techniques and crucial activities for cost reduction during construction were used to produce the kaizen framework. The kaizen framework focused on activities before the construction phase required for effective post-contract control. The kaizen framework was developed using IDEF0, business process model and notation and capability maturity model. Overall, the validated strategic realignment of the post-contract cost control process in the Nigerian construction industry can be attained within five (5) to (6) years of implementing the framework.


Workplace stress, burnout, and well-being among health care workers have in recent years become increasingly recognized as pressing needs. Now, as the pandemic reveals vulnerabilities that are having wide and deep impacts on health care organizations and their human and financial resources, the need for a more structured approach to wellness is apparent.


Abstract The negotiation of the recently concluded U.N. Convention on the Law of the Sea was prolonged and complicated by political, ideological, and economic differences among the parties. A further, insufficiently recognized, source of difficulty concerning the seabed mining regime has been the ambiguous status of the customary law of seabed mining. According to the developed states, seabed mining is within the scope of customary high seas freedoms, while for some developing states seabed exploitation is a recent technological innovation not encompassed by the traditional high seas regime. This paper argues that these differences of legal opinion have led the parties to employ diverse negotiating strategies, and have generated contrasting perceptions of the consequences of the failure to conclude a conventional seabed mining regime. Furthermore, the legal disagreements among the parties reveal that the consensually based, traditional process of forming customary law is under considerable stress, a devel...

The aim of this paper is to explore the speaking difficulties encountered by English language students at Al Margeb University, and to discover the causes of such difficulties. Speaking English has been a vital importance in international communication. Speaking fluent English is a common problem among the nonnative speakers. The second language learners have gone through a variety of cases to learn how to speak not only correct grammar and using the right vocabulary but with correct accent and pronunciation. Many obstacles, therefore, have been known as the predictors of such a problem among the language learners.  According to the review of literature, appropriate speaking instruction was found to be the learners' priority and a field in which they need more attention. In this paper the writer highlight the speaking difficulties encountered by English language students at Al Margeb University, which are considered to be the most urgent for every teacher, such as fear of mistakes, shyness, anxiety, lack of confidence and lack of motivation. This paper can be useful to teachers to consider their language learners' speaking needs in English language teaching and learning context.


Abstract The Cu(II), Ni(II), Co(II) and Zn(II) catalysed dissociation of the cis-diaquobis(malonato)chromate(III) ion has been studied kinetically in perchloric acid solution over a temperature range. Under these conditions k obs = kH[H+] + k cat[M2+] where k obs is the observed first order rate constants and k H and k cat are the appropriate rate constants for the proton and metal ion catalysed pathways respectively. The metal ion exert marked catalytic effects with k cat following the sequence Cu(II) > Ni(II) > Co(II) > Zn(II). A possible mechanism for the metal promoted reaction is proposed and the relevance of these results to the mechanism of the trans → cis isomerisation of [Cr(mal)2(H2O)2]− considered.


The conventional explanation of the rise of the industrial metropolis in the nineteenth century focuses on large-scale urban-industrial growth processes, including specialization, technological change, interregional transportation and communication improvements, and agglomeration economies, but this explanation is improperly specified. An alternative explanation is proposed based on the pivotal role of metropolises as controllers and coordinators of exchlage. Manufacturing concentrated increasingly in metropolises because thiey dominated regional markets. Metropolises specialized in some national market itidustries, but their industrial growth based on these industries simply kept pace with national growthi. New empirical evidence supporting the alternative explanation is presented for metropolises (n=28) for the 1860-1920 period, with a focus on the 1860-1880 period; manufactures were given two-digit SIC codes. The findings imply that explanations of the urban-industrial growth process need to focus on the early stages of the process. The large concentration of the nation's manufacturing in metropolises and their specialization in national market industries is considered a momentous outcome of urban-industrial growth in the United States. Beginning in the 1950s and building on earlier studies (Gras 1922; Haig 1926; McKenzie 1933; Weber 1899), researchers codified an explanation for the rise of the industrial metropolis that remains unchallenged (Duncan & Lieberson 1970; Gordon 1977; Klein & Kantor 1976; Lampard 1955; McKelvey 1963; Perloff et al. 1960; Pred 1966; Wamer 1972). They focused on the dramatic changes in cities and manufacturing during the period of large-scale urban-industrial growth from 1860 to 1920.1 By the latter date, the American economy had completed a transformation from rural to urban and from agriculture to manufacturing: the percentage of the population that was urban first passed 50.0 percent (51.2%), and the percentage of the labor force in manufacturing peaked at 26.9 percent (Lampard 1968:107, Table 1; Lebergott 1966:119, Table 2). Prior to 1860, it was argued, the industrial sectors of metropolises were small-scale and nationally unimportant. Manufacturing consisted of (1) a few mercantile manufactures (entrepot, commerce-serving) related to the role of metropolises as controllers and coordinators of exchange; and (2) a small sector serving local industrial and consumer markets. Manufacturing concentrated in metropolises and they specialized in national market goods during large-scale urban-industrial growth, according to the conventional explanation, because of new or dramatically altered versions of *1 thank Isaac Eberstein, John Kasarda, Martin Martel, Judith Meyer, Dietrich Rueschemeyer, Franklin Wilson, Basil Zimmer, and the referees for their comments on drafts of this paper.

An increase in the division of labor within and among factories raised labor productivity, and technological change, resulting in new and improved machinery for producing goods, enhanced this productivity. The expansion of transportation and communication systems to national scope, improvements in the quality of service, and cost reductions in these systems made large production feasible. These factories located in metropolises, it was argued, because metropolises had three agglomeration economies: economies of scale, localization economies, and urbanization economies. The northeast quarter of the nation, the earliest large market, formed the manufacturing belt consisting of metropolises and other cities. This explanation for the concentration and specialization of manufacturing in metropolises remains unchallenged after three decades. First, this study demonstrates that metropolises were at or near their peak relative importance as industrial centers in the nation before large-scale urban-industrial growth occurred. Rather than national market manufacturing concentrating increasingly in metropolises, their industrial growth simply kept pace with national industrial growth. Because the empirical evidence fails to support the conventional explanation, it is reassessed and concluded that the explanation is improperly specified. An alternative sociological explanation for the concentration and specialization of manufacturing in metropolises is proposed. The pivotal role of metropolises as controllers and coordinators of exchange, it is argued, gave them early advantages as locations for manufacturing related to exchange. Furthermore, as the cities with the largest populations an outcome of their exchange role (finance, wholesaling, transportation, warehousing) metropolises had large consumer markets served by local factories. Both the exchange-related and local consumer manufactures also required intermediate goods that were supplied locally. These manufactures concentrated increasingly in metropolises as their dominance of regional markets grew with intraregional transportation and communication improvements. In contrast to the conventional explanation that discounted their importance, the proposed interpretation claims that these manufactures were the basis for the high concentration of the nation's manufacturing in metropolises. Metropolises also grew because they acquired national market firms, including producers of intermediate goods, but these factories also located outside metropolises. The manufacturing belt included the metropolises that acquired large industrial sectors before national market manufactures became important. Previous research findings support this explanation, and new supporting evidence is presented for the 1860-1920 period, with a focus on the 1860-1880 period.

The rocket nozzle throat is exposed to combustion gas of a high temperature. Therefore, it is important to select suitable material for the nozzle which can maintain its structural integrity at a high temperature and to evaluate the material for proper rocket nozzle design. ATJ graphite, as the candidate material for rocket nozzle throat, is studied. In this study, an experimental method to evaluate compressive fracture behavior of ATJ graphite is presented. In particular, the effects of specimen size, temperature and heating time on compressive strength were investigated. Three types of specimens were used in uniaxial tests at room temperature, where the ratios of diameter to length are 1/2 of ASTM standard specimen, one of type I specimen and 1/0.8 of type II, respectively. Also, two kinds of specimen, which were coated using antioxidant and non-coated respectively were tested at elevated temperature to investigate temperature dependency of compressive strength.


Abstract : There has been a tremendous growth in recent years in the use of data base management systems (DBMS) throughout the world. This has lead to efforts to increase the effectiveness and efficiency of systems designed to create and maintain large databases. The traditional approach has been to select a data model and its associated model-based data language and implement a database system based on that single model. The multi-model and multi-lingual database system (MM&MLDS) was designed to increase the functionality of database systems by allowing the use of multiple data models and several model-based languages on a single system. With this approach, the system could support a heterogeneous collection of databases, each based on the model most appropriate for the individual application requirements. The current implementation of MM&MLDS is restricted in cross-model accessing the available databases. This thesis is part of the effort to remove these restrictions, thereby allowing the databases based on given models to be accessed by database languages associated with different models. The goal of this thesis is to further increase the functionality of MM&MLDS by permitting a user knowledgeable only in a hierarchical-based data language (DL/I) to access and manipulate information in a network database, while strictly maintaining the integrity of the network model.

This paper presents the analysis of static structure and wavefront error (WFE) of a telescope experimental model's primary mirror. The experimental telescope with 280mm diameter primary mirror had been assembled and aligned in 2011. The WFE result was not perfect. In order to find out the root cause of the WFE, the static structure analysis had been applied to the structure model of the telescope assembly. Some assumed effects which may cause deformation of the primary mirror had been proposed, such as gravity effect, iso-static mount (ISM) bonding effect, thermal expansion effect, etc. According to each assumed effect, we established a corresponding model and boundary setup. The numerical model was also analyzed by static structure analysis software and opto-mechanical analysis software to obtain numerical WFE and Zernike polynomials. The numerically synthetic optical system WFE was compared with measured system WFE of the telescope. According to the results of these deformation effects of the primary mirror, we could get the root cause of the system WFE. In the next generation of telescope, the opto-mechanical design and alignment process would be refined, and applied to the new optical system.


This paper presents a solution to the problem of real-time food detection on mobile devices. The solution compares a YOLOv4 tiny model and a multilayer classification neural network ensemble as the convolutional neural network responsible for food detection, using MobilenetV3 for classification and several YOLOv4 tiny models capable of detecting less food in the overall problem. The model was trained with 40 different food categories using an RTX 3070 video card. Results showed that the multilayer network ensemble performed better than a single YOLOv4 tiny model. The TP value was 258 higher, the FP value was 163 lower and the FN value was 773 lower. The accuracy increased from 0,56 to 0,61, the recall increased from 0,52 to 0,70 and the F1-score also increased from 0,54 to 0,65. Finally, the finished models were implemented on an Android mobile device, and the application allows users to log meals and generate statistics from the saved data.


Contraction‐stimulated glucose uptake in skeletal muscle requires Rac1, but the molecular mechanism of its activation is not fully understood. Treadmill running was applied to induce C57BL/6 mouse hind limb skeletal muscle contraction in vivo and electrical pulse stimulation contracted C2C12 myotube cultures in vitro. The protein levels or activities of AMPK or the Rac1‐specific GEF, Tiam1, were manipulated by activators, inhibitors, siRNA‐mediated knockdown, and adenovirus‐mediated expression. Activated Rac1 was detected by a pull‐down assay and immunoblotting. Glucose uptake was measured using the 2‐NBD‐glucose fluorescent analog. Electrical pulse stimulated contraction or treadmill exercise upregulated the expression of Tiam1 in skeletal muscle in an AMPK‐dependent manner. Axin1 siRNA‐mediated knockdown diminished AMPK activation and upregulation of Tiam1 protein expression by contraction. Tiam1 siRNA‐mediated knockdown diminished contraction‐induced Rac1 activation, GLUT4 translocation, and glucose uptake. Contraction increased Tiam1 gene expression and serine phosphorylation of Tiam1 protein via AMPK. These findings suggest Tiam1 is part of an AMPK‐Tiam1‐Rac1 signaling pathway that mediates contraction‐stimulated glucose uptake in skeletal muscle cells and tissue.


Experimental research for four mixing tubes with different sectional area and different axial distance for a axisymmetric lobed nozzle was conducted to investigate the effect of area ratio A m/ A p and axial distance L mp between lobed nozzle and mixing tube on the aerodynamic performances for a lobed exhaust system. The results show that the pumping coefficient increase and synthetic aerodynamic performance of the system can be improved with the increase of A m/ A p.The pumping coefficient and pressure loss coefficient of the system also increase with L mp increase.The slope of pressure loss coefficient with L mp change is different in different range, and the synthetic aerodynamic performance be worse with L mp increase.


This research aimed to study the effectiveness of ethanol extract of binahong leaves on blood glucose, insulin, blood chemical profiles (serum glutamic pyruvate transaminase=SGPT, serum glutamic oxaloacetic transaminase=SGOT, ureum, and creatinine), and skin histopathology in diabetic rat. A total of 20 male Wistar rats aged 3 months (± 250 gram) were divided into five groups, with four rats in each group. Group I (non-diabetic control) was injected with 0.1 M sodium citrate buffer, while group II (diabetic control), III, IV, and V were injected with single dose of Streptozotocin (STZ) at dose 40 mg/kg intraperitoneally (IP). One week after the injection, the dorsal skin of the rats were excised. Group I and II were given cream topically and 1% NaCMC orally, group III was given 50% ethanol extract of binahong leaves (EEB) topically and 1% NaCMC orally, group IV was given cream topically and EEB 300 mg/kg orally, and group V was given 50% EEB topically and EEB 300 mg/kg orally. These treatments were continued for 14 days. Blood samples were obtained at the end of study to examine blood glucose, insulin, and blood chemical profiles (SGOT, SGPT, ureum, and creatinine). Examination of skin histopathology and leukocyte count were also done. The result showed that blood glucose, insulin, SGOT, SGPT, and ureum level of diabetic rats given topical or oral EEB did not significantly different from diabetic control group, even though blood glucose, insulin, SGOT, SGPT, and ureum level of diabetic rats given topical and oral EEB were found lower compared to diabetic control group. Administration of EEB 300 mg/kg orally in diabetic rats could lower creatinine level significantly (P<0.05). Histopathological examination of dorsal skin of diabetic rats which were given EEB topically showed the decrease of fibroblast proliferation, leukocyte infiltration, and hemorrhage in dermis area. Leukocyte count on skin tissue was significantly lower (P<0.05) in diabetic rats given EEB. In conclusion, topical or oral administration of EEB can help healing process in diabetic wound.


The 19th century has brought one of the most dramatic change in the energy system fuelling human activities after the discovery of fire: from a biomass burning society at its beginning to a society obtaining 80% of its primary energy from fossil fuel (coal) burning at its end in western economies. The 20th century has seen two further radical changes: the introduction of two other forms of fossil fuel, oil and gas, enabling the emerging transport industry and the introduction of nuclear power, together reducing the share of coal to less than 20% at the end of the century. Gradually, a consensus has emerged over the last years that, after decades of relative stagnation, the energy sector is bound to undergo substantial changes over coming decades, driven by a combination of energy security and independence concerns, energy competitiveness and e ciency, and energy-related environmental e ects. The space sector has been a lead market for some terrestrial energy technologies. Space-based sensors already allow optimising the location of renewable power plants and improving the e ciency of electric power grids. Technological advances in energy systems for satellites benefit ground applications. While small with respect to the economically large energy sectors, space can significantly contribute to it. Its potential contributions are multiplied by the expected changes to the energy sector for the next decades. This paper provides an analysis of the current status of space and energy related activities and presents an outlook of potential future contributions.


Ukraine is located in an important geographical position in Europe.The oil and gas industry is strategically and economically significant to the country.However,the development of this industry has been suffering from its political and economic environment.A series of problems block the development of the industry,for example: oil and gas supply and transportation constricted by Russia,monopoly of consortium and official corruption.Reform for the oil and gas industry in Ukraine is necessary.


The Confucianism during the late-Ming Dynasty develops on its own, in addition to the external factors. The two historical events worth our attention are the Etiquettes Charter, and Donglin Clan Charter, which give rise to the new tendencies of ideological and social changes. In what is said to be the earlier stage of enlightenment, the Donglin school of the rational social ideology and Taizhou school of the romantic ideology help frame the late-Ming structure of ideology.

Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis does not provide an analytical means to determine the importance of the identified factors or the ability to assess decision alternatives according to these factors. In this paper, we use TOPSIS method to determine strategies priority as a novel innovation. Strengths and opportunities are considered as positive criteria and weaknesses and threats are considered as negative criteria in TOPSIS method. In addition, in order to deal with uncertainty and vagueness of human mind, we incorporate fuzzy logic in the proposed method. Then strategies are prioritized based on the TOPSIS method.


The aim of this study was to examine A Study on Use of Search Engines by the Faculty Members of Sri Ramakrishna College of Arts & Science, Coimbatore, Tamil Nadu. A well-structured questionnaire was distributed among the 176 faculties, out of which 165 duly filled copies were returned, constituting a 96.94 percent response rate. The present study demonstrates and elaborates the various aspects of use of search engines such as, use of arts and science subject search engines, material and liking of search engines, conduct to place the information from the Internet during search engines, troubles faced by the users and satisfaction rank of users though using the search engines. The results of the survey provided some of the reasons that influence the contentment with information recovery results of search engines. Internet has revolutionized the information today. The search engines contain complete searching the Internet very simple. They have emerged as a resolution to the difficulty of accessing in order source on the Net. The study recommends that there is a need to conduct the orientation programmer on search engines to help the faculty members for effective and efficient use of search engines for access the qualitative information available on the web.


Digital Signal Processing (DSP) has evolved as an integrated component in electronics advancement. Among all the DSP operations, Fast Fourier Transform (FFT) plays a prominent role in signal processing. FFT computational time reduces when the number of zero valued inputs (Z) outnumbers the non-zero valued inputs (NZ) due to unnecessary computations for Z. The above issue can be resolved by minimizing computations on Ζ by the method Pruning (Partial, Complete) in FFT. The pruning method is implemented in the hardware and computational time improvement is observed. The FFT Pruning is developed in Verilog and validated on Spartan 3E FPGA (xc3s500e-fg320-5).


We assess the theoretical uncertainties on the inclusive ch arm andJ/ψ production cross sections. We use our new results to provide improved baseline comparis on calculations at RHIC and the LHC. We discuss cold matter effects on J/ψ production at leading relative to next-to-leading order in the CEM and as a function of rapidity, transverse mom entum and centrality. We place these results in the context of the latest RHIC and LHC result s in pp, pAandAAcollisions.


Abstract The signature of the vibration generated by a fault on a gear is carried by the sidebands around the dominant tooth meshing harmonic. This paper applies the linear wavelet transform based on B-spline wavelets to reveal the spectrogram of the sidebands exactly. The proposed wavelet transform uses 1/ a for unit normalisation instead of 1/√ a for energy normalisation, and can be computed easily and efficiently by the fast Fourier transformation. An experimental example demonstrates that the development of a crack in a gear can be monitored simply by examining the spectrograms over a period of time.


Neuroendocrine differentiation and neuroendocrine carcinoma (NEC) have been linked to androgen deprivation in prostate cancers. No previous study has directly connected neuroendocrine phenotypes to chemotherapy. The pathogenesis of prostatic NEC has not yet been determined.


Purpose The main objective of this paper is to determine the effect of the chosen Search Engine Results Page (SERP) on the page count indicator when performing website rankings based on webometric techniques. Design/Methodology/Approach A sample of 100 Spanish rare disease association websites at two moments in time (2016 and 2017) is analysed, obtaining the page count for the first and last SERP in two search engines (Google and Bing). Findings It has been empirically demonstrated that there are differences between the number of hits returned on the first and last SERP in both Google and Bing. These differences are significant when they exceed a threshold value on the first SERP. Research Limitations/Implications Future studies considering other samples, more SERPs, and generating different queries other than web size (<site>) would be desirable to draw more general conclusions on the nature of quantitative data provided by general search engines. Practical implications Selecting a wrong SERP to calculate some metrics (in this case, page count) might provide misleading results, comparisons and performance rankings. The empirical data suggest that the first SERP captures the differences between websites better because it has greater discriminating power and is more appropriate for webometric longitudinal studies. Social implications Findings allow improving future quantitative webometric analyses based on page count metrics in general search engines. Originality/Value The page count variability between SERPs has been empirically analysed, considering two different search engines (Google and Bing), a set of 100 websites focused on a similar market (Spanish rare diseases associations), and two annual samples, making this study the most exhaustive on this issue to date.


An apparatus, for operating a multiplexed 128-bit external bus within a computer system, includes arbitration logic that arbitrates between contending address and data requests according to the number of outstanding data and/or snoop transactions on the external bus. In response to the outcome of this arbitration, selection logic grants the external bus to either the contending address or data request. The arbitration logic may compare the number of outstanding data transactions to a predetermined data threshold number when performing the arbitration, this data threshold number being dynamically alterable by an application program or operating system so as to optimize external bus throughput under predetermined conditions.


Initially written in the form of an essay, this letter is written to my children from a place called Land. It unveils the entanglements coloniality creates in young, racialized, and gendered lives through the colonial logics structuring childhood, memory, and borders. From a diasporic perspective, Land emerges as flesh rooted in the saberes, the knowledge of our mothers and grandmothers. Remembering and returning to the places we call home, in my case, US/Mexico border, help us grapple with trauma and also learn ways people respond to the violence. I illuminate the colonial wounds we bare and the knowledge we carry to suture and heal.


Non-abelian representations of π! of a Kahler manifold X will often put rather strong condition on the geometry of X. For example, there are factorization theorems ([Sl], [S2], [ZI], [Z2], [JZ1] and [JZ2]) which say that a Zariski dense and nonrigid, or p-adic unbounded representation of ni into an almost simple algebraic group must factor through a surjective morphism / : X -> Υ with dim Υ ̂ rkc G. Similar questions have been also studied in [Kl] and [NR].


Published in Cambrai in 1563, Robert du Triez's Les Ruses, finesses et impostures des espritz malins has good claim to the be the first prose demonology published in French. And yet Les Ruses has received surprisingly little scholarly attention. This article offers both an introduction to Du Triez and his text, and some reflections on a blind spot in the historiography of early modern French demonology. Les Ruses might be described as marginal in at least four respects. i) chronology: Du Triez's text appeared some fifteen years before the heyday of vernacular French demonology. ii) geopolitics: an archer in the army of Philip II, Du Triez's allegiances were not to France, but to the Empire, and to the Counter‐Reformation initiatives at the newly founded college at Douai iii) thematics: Les Ruses contains no discussion of witchcraft and the pact. iv) style and tone: the author accords an unusual degree of attention to the question of narrative pleasure. What emerges most powerfully from Les Ruses is that early modern demons were not always so much a matter of what it is we should believe, as the kinds of stories they allow us to tell.

The main section of the present Ph. D. thesis is related to X-band radars. Since 2005 the Remote Sensing Group of Department of Electronics and Telecommunications of Politecnico di Torino developed an X-band mini weather radar as a standalone sensor to measure rain. Some early results have been presented until 2011 showing the proper functioning and it has been decided to realize an experimental and operative integrated network of X-band radar devoted to rain measurement. The network structure deployed during the Ph. D. period is presented, together with the analysis, the study and the realizations of some operative services, calibration procedures (including Quantitative Precipitation Estimation, QPE) and software and applications developed for the institutions which support the network realizations. The design of an innovative and low cost method to check the radar stability and proper functioning is presented: by simply acquiring a large number of ground clutter echoes during clear sky days and computing some analysis, it is shown it is possible to identify some statistical indicators that allow users and radar operators to know if the radar equipments suffered some degradations of failure. The second part of the thesis is dedicated to Wireless Sensor Networks (WSNs). After a study on WSN technologies for environmental monitoring, a first developed prototypal DGPS network is presented. Using the same multipurpose node designed for such network (or its updated releases with very small differences) and varying only their firmware, other two prototypal and fully operative WSNs are described. The designed choices are described for what concern both hardware and software
