Olefin-palladium(II) chloride complexes reacted with n-butylamine to form Schiff's bases. N-Ethylidene-n-butylamine was obtained by the reaction of the ethylene complex with n-butylamine, accompanied by reduction of palladium(II) to the metal. A tris(n-butylamine)palladium chloride complex was formed simultaneously by ligand substitution reaction. The yield of N-ethylidene n-butylamine was 15–19mol% (calcd on palladium) in 2.5 hr at 25°C, and decreased at temperatures higher than 60 °C with increasing reduction of palladium(II), owing to conversion of N-ethylidene-n-butylamine into either N-crotylidene-n-butylamine or a tarry polymeric substance by aldol type condensation reaction. The n-butylamine-palladium(II) chloride complex did not react with ethylene at 25°C, but reacted with ethylene at 150°C to form a large amount of tarry polymer and a small amounts of N-ethylidene-n-butylamine and N-crotylidene-n-butylamine. The propylene complex and the cyclohexene complex reacted with n-butylamine to yield bot...


The aim of this paper is to construct iterative methods to solve non-linear equation with high efficiency index. We proposed a family of iterative methods of optimal order of convergence eight for solving nonlinear equation ( ) = 0, where ( ) is a real valued nonlinear function. It is based on Noor M.A. et al. algorithm [6] and weight function approach. To support the new findings, analysis of convergence and efficiency index are studied. Per iteration these families of methods require three functional evaluations and one evaluation of its derivative, so the method is optimal according to Kung-Traub conjecture [3] which states that an optimal iterative method based on k + 1 evaluations could achieve a maximum convergence order of 2 . The efficiency index of the new eighth order method is 1.682. Several numerical tests show that the proposed methods are more efficient and perform better than classical Newton's method, Noor M.A. et al. method [6] and some other existing method [5],[7].

In this paper, we present a new method for three-dimensional (3-D) medical image fusion for assisting the diagnosis or treatment of kidney disorders, especially acute pyelonephritis. This method consists of three steps: boundary detection, shape analysis and 3-D registration. The boundary detection of the organs was achieved by analyzing texture and intensity variation from SPECT and ultrasound images. A binary shape analysis technique was designed to detect lesion areas. Subsequently, we utilized surface fitting over the boundaries with fast initial pose estimation to integrate images from two different modalities. Experimental results show that the proposed method successfully visualized the functional distribution onto anatomical structure of kidney and assisting physicians to accurately locate the lesion of acute pyelonephritis.

Craniodental remains of a medium-sized beaver from the early middle Miocene of Hambach (MN 5) in the Lower Rhine Basin of northwestern Germany are described and assigned to Steneofiber depereti. The relatively rich material (6 mandibles and 56 isolated teeth) was collected from a single locality, Hambach 6C, and comprises specimens representing juvenile to very old individuals. This makes it possible to assess the morphologic and metric variability of a single population of Steneofiber depereti. Metrically, the mandibular tooth rows compare favorably in size to those of three subspecies described from the Loire Basin in France: Steneofiber depereti janvieri, Steneofiber d. caliodorensis, and Steneofiber d. depereti. Therefore in our opinion, division into subspecies cannot be applied to S. depereti in general. The difference in size between the smaller beaver from Hambach and the contemporaneous larger S. d. carnutense from the Loire Basin is remarkable. The taxonomy of early middle Miocene medium-sized castorids, referred to Steneofiber depereti, Steneofiber subpyrenaicus, and Chalicomys jaegeri is discussed. The presence of the derived beaver C. jaegeri in MN 4 to MN 6 is questioned and assignment to Steneofiber suggested. The occasional appearance of single C. jaegeri features in S. depereti supports the existence of a European lineage from the Orleanian S. depereti to the Vallesian C. jaegeri. The taxonomic status of S. subpyrenaicus remains unresolved.


e18512 Background: Solitary plasmacytoma is a rare plasma-cell neoplasm. We wanted to assess the outcome and prognostic factors in patients with solitary plasmacytoma. Methods: The data from 79 patients with bone (n=55), and/or extramedullary (n=25) solitary plasmacytoma with no evidence of multiple myeloma treated with definitive radiation at a single institution from 1988-2007 were collected. The median follow-up time was 56 months. A serum myeloma protein was present in 36 patients (46%), and Bence Jones proteinuria was present in 24 patients (31%). The median radiation dose was 45 Gy. Overall-survival, local control, and freedom from multiple-myeloma progression were calculated actuarially. Results: The five-year overall survival rate was 78%. The median overall survival was 11 years. Local control was achieved in 72 patients (91%). Radiation dose above or below 45 Gy was not a predictor of local control (p=0.452). The five-year probability of progression to multiple myeloma in all patients was 47%. T...


Women, whether in employment or not, spend a significant amount of time in Turkey occupied in unpaid home-based care activities, providing care for children and the elderly in their families. Among OECD countries, the country ranks second in terms of the amount of time women spend on unpaid household chores and activities. This paper estimates the economic value of time women allocate in Turkey to direct care activities at home by using two main methodologies: (i) the opportunity cost method estimates the value of time using each woman's potential earnings in the labor market, and (ii) the proxy good method calculates the value of time taking into account a constant fixed value of hourly earnings (either the minimum wage or the average wage of a social worker). The value of direct care, which constitutes a lower-bound for overall care activities of women, is estimated to be around 1.37-3.34 percent of GDP as of 2011. Using the opportunity cost of earnings methodology, the paper estimates the economic value of refocusing the time spent on care activities to employment to be 1.5 billion USD for working women and 4.8 billion USD for non-working women.


A case is directed at digital immigrants to utilize mobile computing devices such as an Apple iPod to deliver content to students in self-contained special education classrooms. The author discusses the current state of the use of iPods in classrooms, and how research using these devices has been limited to institutions of higher learning, while leaving the K-12 arena almost devoid of use. Research using this mode of treatment is in its infancy, leaving the field wide-open for willing participants with tremendous upside for the students we are teaching. Podcasting and Digital Video in the Classroom Often times, finding a method of service delivery that works in our classrooms is a difficult proposition. With the relatively small numbers of students we work with in selfcontained classrooms, many companies don't find it economically feasible to develop products for utilization in our classrooms that we can purchase for a reasonable amount, so commercial products are often out of the question. However, with the trappings of NCLB and the requisite assessments that are now becoming inherent in our classroom domain, it is imperative that we find some ways on our own to develop content that can be successfully used over and over again with our students. Video has a tremendous advantage over other methods, since all we need to do to replicate the last lesson is to rewind and press the 'play' button. Many of us as digital immigrants, however, still have a difficult time accepting and using technology in our classrooms. We must realize that our students process information much differently than we ever did (Prensky, 2001), and that we need to change our ways of content delivery if the students are going to be successful. Just because our students have a disability does not preclude them from being able to avail themselves of new technologies. Of late, many methods of utilizing video in the classroom have been delivered to students using a new technology that better suits the student population and their ability to interact with the medium. Over the last 20 years, there have been a number of studies that have addressed the use of video in a variety of formats in classrooms serving moderate and severely intellectually disabled students along with students who have been classified as being autistic. In a review of the literature by Mechling (2005), 24 studies from 1999 to 2003 that utilized a form of video were investigated. Findings from the analysis included the identification of six different video procedures that had recently been utilized. Those methods included video feedback, video modeling (VM), video self-modeling (VSM),


The author describes the adaptive Viterbi coherent detection (AVCD) of MPSK signals. The adaptive LMS channel estimation used requires no knowledge of channel statistical properties. The simulated BER performances in fast Rayleigh fading and AWGN channels are reported.


An outdoor high-voltage vacuum breaker operating mechanism is used for operation and driving of breakers, comprising a frame, a main shaft, an energy storage motor, a spring regulating lever, a switching spring and a position switch connected with the spring regulating lever, a ratchet wheel mounted on the main shaft, a cam, a latch shaft connected with the cam, a switching half axis connected with a latch hook on the latch shaft, an output regulating lever connected with the switching half axis, a switching electromagnet and a switching hand shank. The process of the action is as follow: When the energy storage motor is powered on or the hand shank is manually turned, the main shaft is driven; then the spring regulating lever operates to enable the switching spring to store energy; meanwhile the cam on the main shaft halves the latch hook on the latch shaft and restricts the switching half axis, when the switching half axis is turned electrically or manually to release the restriction on the latch hook, the switching operation is realized. The utility model is simple in structure, suitable for miniaturization, saving space, reducing mechanical friction and promoting reliability. The utility model is universal, both electrically and manually operated, and easy in operation.


The 2016 Snook Prize has been awarded to Diego Tapias, Alessandro Bravetti, and David Sanders for their paper -- Ergodicity of One-Dimensional Systems Coupled to the Logistic Thermostat. They introduced a relatively stiff hyperbolic tangent thermostat force and successfully tested its ability to reproduce Gibbs' canonical distribution for the harmonic oscillator, the quartic oscillator, and the Mexican Hat potentials. Their work constitutes an effective response to the 2016 Ian Snook Prize Award goal -- Finding ergodic algorithms for Gibbs' canonical ensemble using a single thermostat variable. We confirm their work here and highlight an interesting feature of the Mexican Hat problem when it is solved with an adaptive integrator.


The aim of this study was to investigate the car wash wastewater using corncob. Corncob was removed successfully the organic and anorgnic matters in the car wash wastewater at the following optimal parameters: 10 g/L of corncob, 150 rpm of mixing rate and from 6 to 7 of pH. The removal efficiency of turbidity, TDS (Total Dissolved Solid), and ABS (AlkylBenzene Sulfonates) were very high, more than 96%. However COD (Chemical Oxygen Demand), TN (Total Nitrogen) and TP (Total Phosphorus) was found to be 63-65%, 83-87% and 83-84%, respectively, and was relatively low removal efficiency compared turbidity, TDS and ABS. In particular, COD and TP exceeded the wastewater discharge standard and it is considered that post-treatment is necessary for stable treatment of car wash wastewater. Despite the low COD removal, treating car wash wastewater using corncob is very attractive. Because corncob can be treated with abandoned agricultural by-products to treat wastewater, and environmentally friendly because they are not using chemicals. Especially, turbidity, TDS and ABS have high removal efficiency, so that it is possible to reduce the processing cost of wastewater treatment if they are used as pre-treatment.


The study was conducted to evaluate the effect of prosopis africana seed coat meal (PASCM) on the performance and nutrient utilization of three hundred (300) Nera brown day-old pullet chicks that were fed for 56 days. The birds were randomly allotted to 5 experimental diets with 3 replications of 20 birds each. The diets were formulated with the inclusion of PASCM at 0, 15, 20, 25 and 30% levels, respectively and the data collected were subjected to analysis of Variance in a completely randomized design. Results obtained showed that the 0%(control diet) had the highest feed intake of 31.94g/bird/day. While the best FCR (3.09) and highest final weight gain (608.33g/bird) were obtained in 0% PASCM inclusion level. Also birds on 0% PASCM inclusion level had the highest value of weight gain (10.33g/bird) and best protein efficiency ratio (0.64). Mortality was not observed. The digestible CP and EE were highest (P 0.05) from 15% and 20% inclusion levels. It was therefore concluded that 20% PASCM inclusion level could be adopted for optimum growth performance and digestibility in pullet chicks' diets.


The changes in the United States-Mexico-Canada Agreement (USMCA) for the textiles, apparel, and agriculture sectors are relatively minor, although they reflect somewhat greater protectionism, particularly with textiles and apparel. In terms of the agriculture industry, the USMCA modestly liberalizes U.S. dairy market access to Canada, and U.S. wine growers receive greater access to Canadian markets. Wine and cheese exporters to Mexico also receive significant protection from limitations on the use of common geographical indications in Mexico as a result of Mexican negotiations with the European Union (E.U.) on a revised free trade agreement.


Abstract With a resolution of 4.4 × 10 −3 cm −1 , we were able to identify in this range the very weak ν 2 + 2ν 0 4 ( A 1 ) component near 1180 cm −1 , the ν 3 + ν 4 band around 1205 cm −1 with its ( A 1 + A 2 ) and E very intermixed components, and the ν 1 + ν 4 ( E ) band centered at 1238 cm −1 . Three thousand six hundred transitions belonging to the (ν 3 + ν 4 , ν 1 + ν 4 ) interacting system were fitted together with a model taking into account l (2, 2) interactions inside ν 1 + ν 4 and between ( A 1 + A 2 ) and E components of ν 3 + ν 4 , the l -vibrational resonance inside ν 3 + ν 4 ( A 1 + A 2 ), and the Coriolis interactions between ν 1 + ν 4 and ν 3 + ν 4 ( A 1 + A 2 ) on one hand and between ν 1 + ν 4 and ν 3 + ν 4 ( E ) on the other. Four available MW transitions were also included in the fit. A rms of 0.76 × 10 −3 cm −1 was obtained with 34 free parameters among 38. Normally the Fermi resonance, which links ν 3 to ν 2 + ν 4 with a coupling term W 234 = 2.86 cm −1 , must connect each component of ν 3 + ν 4 with each component of ν 2 + 2ν 4 . But since we have only little experimental information about the weak ν 2 + 2ν 0 4 component (120 assigned lines) and none about the dark ν 2 + 2ν ±2 4 component, it was not possible to introduce this resonance in the fit. However, the bandcenters' shifts were calculated since the basic coupling term W 234 and the anharmonic constant x 24 are well known. Therefore, according to this approximation, the very sensitive anharmonic constants x 34 and g 34 could be deduced. Of course the x 14 Fermi-independent constant, derived directly from the (ν 1 + ν 4 ) 0 bandcenter given by the fit, was certainly more accurate.


Abstract To characterize genetically the Muslim population of Punjab, a north–west Indian state, a biochemical genetics investigation using red cell enzyme markers was planned. For this, blood samples from a total of 992 Muslim subjects, belonging to the Sunni (803) and Shia (189) endogamous sects inhabiting Malerkotla town were collected. Haemolysates were analysed for the phenotypes of seven different polymorphic red cell enzymes viz., Acid Phosphatase locus 1, Phosphoglucomutase locus 1, Adenylate Kinase locus 1, Adenosine Deaminase, Phosphohexose Isomerase, Esterase D and Glyoxalase locus 1, following standard electrophoretic techniques. The results of the present study demonstrate that there were no significant genetic differences between the Sunni and Shia Muslim populations of Malerkotla and their genetic constitutions were similar. Compared with their counterparts reported from various other states of India, the two Muslim groups studied here from Punjab were found to be genetically homogeneous with most of them.


Disciple of Merleau-Ponty, the German philosopher Bernhard Waldenfels is also one of the most important and current thinkers specialized on the concept of the alien. Likewise, as Waldenfels sustains, Merleau-Ponty significantly influenced his thought. The present work will approach in a first moment on the definition of the alien, to give place later to the merleaupontian concept of institution which will allow to expose some of the similarities and divergences upon these two thinkers. Finally, it will go deeper on the instituting and contingent sense of the phenomenon of the alien.


In this paper, we propose a secure intra-vehicular wireless communication architecture based on Host Identity Protocol (HIP). It ultimately improves the security of wireless intra-vehicular communication systems. The performance evaluation of the proposed architecture is performed in a ski tunnel which emulates the real underground transportation environment. Our results verify the feasibility of proposed architecture by providing required level of service quality. Also, it outperforms the existing secure architectures. More importantly, the proposed architecture protect the wireless intra-vehicular communication system from IP based attacks.


Cluster growth on nanostructured materials is of interest in many fields among them catalysis, nanoelectronics and thermal transport in micro and nanodevices. Recent experiments displayed interesting behavior of nanoclusters embedding carbon nanofibers and nanotubes. Especially, plasma sputtered platinum clusters are suitable as electrodes catalysts for low temperature fuel cells. Plasma sputtered Ni, Ti and W layers have interesting properties as photothermal transducers for thermal characterization of embedded nanotubes by using a UV pulsed photothermal method. In this method, metal clusters are able to absorb a high amount of UV photons leading to a rapid surface temperature rise, and then to a high IR radiation (especially for Ti). Molecular dynamics simulations are carried out for understanding the early stages of such nanosized films especially the cluster growth steps along the carbon nanofibers. These molecular dynamics simulation are aimed to understand growth phenomena of fuel cell electrodes and photothermal transducers. For this study, amorphous model carbon nanofibers of 40 nm in height and 20 nm in diameter are built. Due to periodic boundary conditions, this represents periodic array of nanofibers. The metal deposition is simulated by injecting atom each two ps. This is a suitable time delay allowing thermal relaxation of deposited atoms. Metal interaction potential is chosen as the so-called analytical tight binding - second moment approximation while metal-carbon interaction are modeled by Lennard-Jones potential as available in the literature. Relevant properties as sticking coefficients, concentration profiles along the nanofibers, cluster size distribution are calculated and compared against the properties of the impinging atoms (energy and angular distribution), which is a function of plasma deposition parameters (as pressure).


A new electron gun with electrostatic compression has been installed at the Electron Beam Ion Source (EBIS) Test Stand at BNL. This is a collaborative effort by BNL and CERN teams with a common goal to study an EBIS with electron beam current up to 10 A, current density up to 10,000 A/cm2 and energy more than 50 keV. Intensive and pure beams of heavy highly charged ions with mass-to-charge ratio < 4.5 are requested by many heavy ion research facilities including NASA Space Radiation Laboratory (NSRL) at BNL and HIE-ISOLDE at CERN. With a multiampere electron gun, the EBIS should be capable of delivering highly charged ions for both RHIC facility applications at BNL and for ISOLDE experiments at CERN. Details of the electron gun simulations and design, and the Test EBIS electrostatic and magnetostatic structures with the new electron gun are presented. The experimental results of the electron beam transmission are given.

For the reinforcement of railway road bed, the authors have conducted full-size model tests of the road bed structure reinforced with three-dimensional reinforcement material which is called "geocell" in this paper. In both rolling compaction test and cyclic loading test, we compare the performance of two types of structure: with geocell and without geocell. The results show that the road bed structure reinforced with geocell has higher performance of dynamic and residual property than the usual structure without geocell.


Rank (i.e., top-
 k
 ) join queries play a key role in modern analytics tasks. However, despite their importance and unlike centralized settings, they have been completely overlooked in cloud NoSQL settings. We attempt to fill this gap: We contribute a suite of solutions and study their performance comprehensively. Baseline solutions are offered using SQL-like languages (like Hive and Pig), based on MapReduce jobs. We first provide solutions that are based on specialized indices, which may themselves be accessed using either MapReduce or coordinator-based strategies. The first index-based solution is based on inverted indices, which are accessed with MapReduce jobs. The second index-based solution adapts a popular centralized rank-join algorithm. We further contribute a novel statistical structure comprising histograms and Bloom filters, which forms the basis for the third index-based solution. We provide (i) MapReduce algorithms showing how to build these indices and statistical structures, (ii) algorithms to allow for online updates to these indices, and (iii) query processing algorithms utilizing them. We implemented all algorithms in Hadoop (HDFS) and HBase and tested them on TPC-H datasets of various scales, utilizing different queries on tables of various sizes and different score-attribute distributions. We ported our implementations to Amazon EC2 and "in-house" lab clusters of various scales. We provide performance results for three metrics: query execution time, network bandwidth consumption, and dollar-cost for query execution.


Coastal waters are highly dynamic. Tides, diurnal winds, river runoff, upwelling and storm winds drive currents from one to several knots. Three hour or better sampling is required to resolve these features, and to track red tides, oil spills or other features of concern for coastal environmental management. To provide this capability NOAA is planning to include hyperspectral coastal waters imaging (HES-CW) as part of the hyperspectral environment suite (HES) on the next generation Geostationary Operational Environmental Satellite (GOES-R) to be launched in 2012. The HES-CW will image the U.S. coastal waters once every three hours, with selected regions hourly. It will have 300 m spatial resolution and the high signal-to-noise ratio necessary for coastal imaging. To prepare for HES-CW NOAA has formed the Coastal Ocean Applications and Science Team (COAST). COAST goals are to assure that ocean applications and science requirements are met and to help NOAA prepare for the immediate use of the data when HES-CW is launched. This presentation describes the HES-CW requirements, current status and the activities of the COAST team to prepare for HES-CW


A versatile Mossbauer diffractometer using a microcomputer as devised to separate the elastic scattered intensity and the inelastic one in the vicinity of Bragg reflections. In order to do the separation automatically, a selective modulator is used, which can make a transducer move at a resonant velocity and at a nonresonant one alternately. It is well known that Mossbauer diffractometry has a great deal of possibilities in crystalline and magnetic structure investigations /1,2/. However, mainly because of a low couting rate available, Mossbauer diffraction experiments usually need a long measuring time. This is the reason why it is not so popular as X-ray diffraction. Recently a few interesting experiments have been published, where Rayleigh scattering of y~ray was used for the purpose of separating elastic components and inelastic one of the scattered intensity in the vicinity of Bragg reflections. In this paper, a versatile Mossbauer diffractometer using a microcomputer is described, by which the separation can made automatically. The diffractometer is composed of a goniometer driven by two stepping motors, two velocity transducers, a selective modulator and a microcomputer. Tosmic12 microcomputer is used as a controller of the goniometer and as a two-input recording unit. As shown in figure 1, a two-channel stepping motor interface module (PMI), a two-input pulse counter module (PCM) and a digital I/O module (DI01) are used to control the goniometer.Given a stepping number ranging 1 to 255, a scanning direction and a scanning velocity of 512 Hz or 16 Hz, PMI transfers driving pulses and a signal of forward or reverse rotation to the stepping motor of the goniometer at each channel. When a stepping number counts down and becomes zero at a step counter of PMI, PMI interrupts a CPU. By the command from the CPU, the step counter is reset to zero and driving pulses stop. PCM counts feedback pulses from a driving circuit of the stepping motor, and according to the command from the CPU, PCM sends a content of the counter to the CPU at each channel. PCM interrupts the CPU when counts exceed 4095. Only input ports of DI01 are used to protect the goniometer from an overrun and to set a zero angle at 0 and 20 automatically. The two-input recording unit for the counting operation at a resonant velocity and at a nonresonant one is composed of two pulse counters having a time base (TBPI1), 2 K (12 bit) Bulk RAM (BRAM) and a analog output module (A01). At TBPI1, counting operation can be controlled by a inner or outer clock and inhibit pulses. When a setting time counts down and becomes zero, TBPI1 interrupts the CPU. TBPI1 interrupts the CPU when counts exceeds 4095. Fig. 1 : Block diagram of the Mossbauer diffractometer. During a flyback of the velocity transducer, an inhibit pulse is generated at a driver of the velocity transducer. The inhibit pulse is used to inhibit counting operation of TBPI1. Outputs of TBPI1 are stored in BRAM, and two words in BRAM are used for each angular point. The counting capacity is 2-1. Angular points Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jphyscol:1979212 C2-40 JOURNAL DE PHYSIQUE are selectable ranging 1 to 512 for each of two inputs. Data in BRAM are figured at a oscilloscope through A0 1. The selective modulator was constructed to make one of two velocity transducers move and stop alternately in a combination of two modes among constant acceleration mode, constant velocity mode and internal mode (manual selection of a velocity) at two velocity transducers 131. At internal mode the selective modulator can make a velocity transducer move at a resonant velocity and at a nonresonant one alternately, and can sort couting operaBy means of the selective modulator, the separation of the elastic scattered intensity and the inelastic one could be done automatically. The remainder of the diffractometer comprises an intrinsic germanium detector, amplifier, single channel analyzer, Liq. N p cryostat, temperature controller and Gssbauer drive system. In figure 2, the program flow diagram is shown. After keying in a measuring condition at a teletype, measurement is done automatically. Using the diffractometer, the experiments have been done on SrTiOs single crystal for investigating tions at a resonance and at a nonresonance. its lattice dynamics. move t o zero pos i t ion *, I 1 move t o i n i t i a l pos i t ion I 1 I I 1 output data t o CRT [ a t each t a b l e I I 1 print a count number I move with s t e p number a t 0, 2


Objective:To show the usefulness of the Barber and Johnson diagram to analyze comparatively the productivity and management of hospital bed use in centers of National Health System in Costa Rica. Methods: Hospital beds, inpatient registers and total patient days for 2011 come from Caja Costarricense de Seguro Social. Barber and Johnson Diagram were used to compare indicators of length of stay, occupancy rate, turnover interval and discharges per bed in a year. Efficient centers were considered when the occupancy rate is less to 85% and the discharges per bed in a year are in a range between average plus or minus one standard deviation. Results: In 2011, the public hospitals have 5 613 available beds that hosted 323 thousand patients, with a consumption of 1,73 million days of stay. Eight hospitals are located in the efficiency area.This group is composed of one national hospital, six regionals and one low-complexity hospital. Conclusion: The Barber and Johnson diagram is a tool to assess graphically the relationship of four traditional indicators of management and productivity of the bed, in order to identify areas for improvement in the relations of medical and administrative work in the use of the hospital bed.


ObjectiveTo measure the quality of life(QOL) in patients with acute exacerbation of COPD (AECO(PD) and) the frequency of potential risk factors, and to evaluate the association of risk factors with poor QOL in patients with AECOPD.MethodsA study sample of 196 patients with moderate to severe COPD admitted for acute exacerbations to two large general hospitals were studied. The St George QOL (SGQOL) scale, socio-demographic, clinical and patient care characteristics, including depression and spirometry were ascertained in the stable state before discharge and at one-month post discharge.ResultsThere was a high prevalence of current or ex-heavy smokers, depression and consumption of psychotropic drugs, and low prevalence of care giver support, pulmonary rehabilitation and vaccination. The mean scores for the different domains were 55.9 for symptoms; 65.1 for activity; 32.9 for impact; and the mean of overall total scores was 46.5. Multiple regression analysis showed that CMH, male, depression, previous frequent hospital readmissions and poor therapy compliance were independently related to worse Symptoms Scores. Previous frequent readmissions, depression, severe dyspnea and older age (72 years) were related to worse Activity Scores of SGQOL. Depression, previous frequent readmissions, severe dyspnea, long COPD duration(5years) and severe smoking were related to worse Impact Scores of SGQOL. Depression, previous frequent readmissions, severe dyspnea and long COPD duration(5years) were independently related to worse Total Scores of SGQOL.Conclusion(Poor QOL) in patients with COPD exacerbation is associated with severity of the disease, as well as psychosocial and health care factors which are modifiable.


One of the gentle surprises of the release of the Tallinn 2.0 Manual is that it has prompted a rich debate over the nature of sovereignty in international law. In hindsight, this should not be too surprising. The modern, Westphalian project of international law is built in large measure around the state and its borders. The emergence of a technology that so readily defies those borders was bound to kick up some interpretive dust. And it appears to have done even more than that. Depending on your perspective, the Tallinn translation of international law to the cyber domain has either forced a reconsideration or surfaced a latent dispute over whether sovereignty is a binding rule of international law at all.


T tHE impact of the oil boom is most readily apparent in the cities of Tripoli and Benghazi. Here the oil companies have their offices and workshops and employ large staffs. New hotels are being built and other businesses have grown as a result of petroleum activity. Purchasing power is concentrated here and the sharp rise of prices, particularly in the case of goods and services consumed by foreigners and the wealthier Libyans, is most strongly felt. And here the mushrooming shanty-towns are bleak reminders that there are some social problems which the discovery of oil will not by itself solve. By contrast, the rural economy, except for a few large farms run mainly by non-Libyans, appears to be relatively unaffected by the surge of business activity. To the casual observer, life outside the cities continues to follow the traditional pattern and provide a comforting element of stability. However, a closer look reveals that important and fundamental changes are taking place in the rural areas. In the Fezzan some villages are all but deserted. Only the aged, the women, and the children remain. The manually-operated wells have been abandoned, and sand has reclaimed the once-productive gardens. In the Shati Valley the young palms are not watered even though an estimated four million gallons of artesian water are lost daily due to run-off and evaporation. In the mountains behind Tripoli the movement, mainly of young people, away from agriculture has been encouraged by two years of drought. An elaborate system of terraces and irrigation canals has been neglected, and the men, some with their families, have gone either to Tripoli or to the district headquarters where they idly pass the time awaiting a grain distribution, or possibly a job with an oil company. Even in the more favored coastal belt, where standing water is found and intensive cultivation is possible, much good land is unworked. The


Obesity and overweight are creating a global epidemic. They are the risk factors for many non-communicable diseases. Rapidly changing diets and lifestyles are fueling the global obesity epidemic. Once being considered as a problem related to affluence, obesity is now growing fast in many developing countries. A study on health complications and activity pattern of obese women from Parbhani city was carried out . Total 210 obese women of age group 30 to 60 years from overweight (120) and obese (90) areas of Parbhani District of Maharashtra was purposively selected. The general information, health status and activity pattern by the obese women were obtained through a well- structured interview schedule. Lipid profile and blood glucose was estimated for a sub sample of 75 subjects who were willing to give blood sample. Blood pressure of a sub sample of 75 selected women was measured. Results of the study revealed that the values of serum cholesterol and triglyceride observed to be high in obese women. The values of HDL and LDL cholesterol of all the women subjects were found to be in the normal category. The values of VLDL cholesterol was observed to be at higher side in (72 per cent) women.Sixty per cent obese women were having normal blood glucose values whereas significantly more number of studied women were suffering from hypertension. From the study it can be concluded that respondents from both the groups were spending their leisure time on watching T.V. as watching T.V. is a sedentary activity which results in less energy expenditure and may lead to development of overweight and obesity.


This work presents a novel method for detecting newly built-up areas in Very High Resolution satellite imagery using Fully Convolutional Neural Networks. The architecture builds on Early Fusion concept where the pairs of image patches are concatenated before inputting into the network as different color channels. The model was trained on different sensors (Pléiades, Kompsat and Superview) using the labels from the Urban Atlas change maps (2012-2018). The results demonstrate the potential of the proposed method for a pan-European mapping of changes in built-up areas at a spatial resolution of 2 meters in the framework of the European Settlement Map of the Joint Research Centre.


Mechanistic models for sediment transport on hillslopes are needed for applications ranging from landscape evolution to debris‐flow hazards. Progress has been made for soil‐mantled landscapes; however, little is known about sediment production and transport in bedrock landscapes that often maintain a patchy soil mantle, even though slopes exceed the angle of repose. Herein we investigate the hypothesis that patchy soil cover is stable on steep slopes due to local roughness such as vegetation dams that trap sediment upslope. To quantify local sediment storage, we developed a new theory and tested it against tilt‐table experiments. Results show that trapped sediment volume scales with the cube of dam width. Where the dam width is less than about fifty grain diameters, particle force chains appear to enhance stability, resulting in greater trapped volumes and sediment‐pile slopes that exceed the angle of repose. Trapped volumes are greatest for hillslopes that just exceed the friction slope and are independent of hillslope gradient for gradients greater than about twice the friction slope. For neighboring dams spaced less than about five grain diameters apart, grain bridging results in a single sediment pile that is larger than the sum of individual piles. This work provides a mass‐conserving framework for quantifying sediment storage and nonlocal transport in bedrock landscapes. Results may explain the rapid increase in sediment yield following wildfire in steep terrain in the absence of rainfall; as sediment dams are incinerated, particles become gravitationally unstable and move rapidly downslope as dry ravel.


This paper presents an investigation of the low
frequency noise properties of SiGe based n MODFET's
through the characterization of both the gate current noise
and the drain current noise including their correlation.
Measurements versus bias and gate geometry have shown
that this noise is generated through mobility fluctuations or
carrier diffusion at the gate terminal and that carrier
number fluctuations are involved in drain current
fluctuations. Microwave residual phase noise measurements
have shown that the up-conversion effect mainly occurs on
the drain current noise.

The NAEPP convenes an 11-member Expert Panel as often as it deems necessary to update its guidelines for the diagnosis and management of asthma. The fields of allergy and immunology, family practice, internal medicine, pediatrics, pharmacology, public health, and pulmonary medicine are represented on the panel. On June 10, the NAEPP issued an update of 6 selected topics in the asthma guidelines that the Expert Panel based on its review of scientific evidence.


This Bachelor's thesis deals with enzyme kinetics, examining the time-course of the reaction catalyzed by the enzyme horseradish peroxidase from the group of oxidoreductases. The enzyme activity was measured spectrophotometrically and fluorimetrically. The theoretical part of my thesis is devoted to the issue of enzymes, contains a more detailed description of the kinetics of enzymatic reactions with one substrate and at the end of this section describes the basic principles of optical methods and focusing on their use in enzyme analysis. The practical part is mainly engaged in measuring enzyme kinetics of the reaction system containing the enzyme horseradish peroxidase, substrate Amplex UltraRed with constant concentration and hydrogen peroxide solution of different concentrations. Part of my thesis is the study of inhibition of the enzyme reaction, too. The result of this thesis is calculated initial speed v0 and rate constants k2 of the enzyme reaction at a constant concentration of the substrate in the reaction system and various concentrations of hydrogen peroxide, as well as experiment instruction of dealing with the enzyme kinetics for teaching analytical chemistry.


-A novel half-wavelength resonator with small size and high Q is proposed for the first time in the world. Two folded quarter-wavelength resonators are vertically stacked owing to the multilayer nature of LTCC (low temperature co-fired ceramic). Each electrode part is connected with via holes. It is named as "VSRR" (Vertical Split Ring Resonator). The super miniature size with high Q is obtained by this structure. The resonance frequency is easily calculated by circuit model and 3D EM simulation as well. The performance of experimental resonators shows good agreement with theory.


Invasive species pose major threats to the integrity and functioning of ecosystems. When such species alter ecosystem processes, they have the potential to change the environmental context in which other species survive and reproduce and may also facilitate the invasion of additional species. We describe impacts of an invasive N2-fixing tree, Falcataria moluccana, on some of the last intact remnants of native wet lowland forest undergoing primary succession on 48-, 213-, and 300-yr-old lava flows of Kilauea Volcano on the island of Hawai'i. We measured litterfall, soil nitrogen (N) and phosphorus (P) availability, light availability, species composition, and forest structure in native-dominated stands and in stands invaded by Falcataria. Litter inputs increased 1.3–8.6 times, N mass of litterfall increased 4–55 times, and P mass of litterfall increased 2–28 times in invaded stands relative to native stands. C:N and C:P ratios of litterfall were lower, and N:P ratios higher, in invaded stands relative to native stands. Resin-captured soil N and P values were 17–121 and 2–24 times greater, respectively, in invaded stands relative to native stands on each of the three lava flows. Native species accounted for nearly 100% of total basal area and stem density in native stands, while alien species accounted for 68– 99% of total basal area, and 82–91% of total stem density, in invaded stands. Compositional changes following Falcataria invasion were due both to increases in alien species, particularly Psidium cattleianum, and decreases in native species, particularly Metrosideros polymorpha. Results provide a clear example of how invasive tree species, by modifying the function and structure of the ecosystems that they invade, can facilitate invasion by additional nonnative species and eliminate dominant native species. Given the rarity and limited extent of remaining native-dominated wet lowland forests in Hawaii, and the degree to which Falcataria invasion alters them, we expect that the continued existence of these unique ecosystems will be determined, in large part, by the spread of this invasive species.


The article dwells on the functional aspects of research in regard to small and middlesized entrepreneurship under the conditions of market economy. The influence of small and middle-sized entrepreneurship upon macroeconomic processes is analyzed especially. The author deals also with the problems of financing and support in reference to entrepreneurship.


The relationship between Gregory of Nyssa's theological conclusions and his philosophy and spirituality demonstrates how he views the function of theological epinoia iconically. This iconic function oftheological epinoia can be analyzed by monitoring one's gaze from its inception in relation to sensible objects through to its culmination as the ontological transformation of the soul into the image of God. Theological epinoiai develop as a result of the noetic process. This process begins when one accumulates information from material objects through the senses. This information is relayed by the soul to the mind where a conceptual image is formed. However, since the divine essence is invisible and imperceptible, this image is formed in the mind using categories from the sensible realm, which are subsequently conferred onto the divine essence. This is the apophatic problem. The divine essence is therefore contemplated using social analogies and spoken of using a universally acknowledged grammar of divinity. It can be determined that Gregory views theological epinoia iconically not only because of the prevailing sight motif occupying much of his thought, but also because his epistemology ensures the limited yet necessary function of concepts in theology. Because theological epinoiai are formed by observing God's operations in the sensible realm, they can enable a human to extend beyond conceptual interpretations by transforming into the divine likeness. The 'ontological gaze' thus emerges as a result of the soul transf01111ing into the image of God. To the extent that this occurs, the 'ontological gaze' from the 'eye of the soul' is positioned on and directed towards the external divine essence.


This thesis examines the 'remembering' of the rebellion of 1857 in India through a constellation of texts, primarily though not exclusively literary, written in Urdu, Hindi and English. An essential concern of the thesis is the imbrication of literary forms, practices and histories with History 'proper' (located within a spectrum of Memory Studies drawing from Walter Benjamin). 1857 stands as a reflective space for the experiences of the rebellion as well as a moment of epistemic break insofar as it signals the consolidation of colonial modernity and its cultural transformations. The Saidian concept of contrapuntal criticism informs the thesis as it foregrounds various Indian texts spread over a century and a half, sometimes in distinct dialogue with imperial texts and strategies, and more generally with the historically constituted idea of Indian silence on the rebellion. The various configurations and matrices of silence, forgetting and speech form a continuous engagement. Chapter One studies an 1863 poetic anthology, arguing for the multivalent, often resistant politics within the conventional Urdu modality of lament. Chapter Two is a wide ranging analysis of texts from 1858 until 1888, focussing on the Enlightenment modality of 'reason' to probe the politics of 'causes of the revolt' narratives, the place of Syed Ahmad Khan therein, and the literary reflection of processes of minoritisation. Chapter 3 examines the multiple recastings of 1857 in the twentieth century nationalist phase. Beginning with V.D.Savarkar's 1909 book, The Indian War of Independence 1857, I focus on uneasy resolutions of Indian modernity particularly with reference to questions of violence and community. The final chapter engages with postcolonial writings that occupy a contrapuntal position in relation to dominant narratives of nationhood and modernity on the subcontinent, in which memory of 1857 gets configured as a point of crisis and of the surfacing of submerged narratives.


The purpose of the study was to establish a simple and robust technique that can be used to predict fatigued and non-fatigued muscle by surface electromyography (sEMG). Muscle fatigue is often caused by unhealthy work practices and recovery may take longer when the fatigue tolerable limit is exceeded. Instantly, it is difficult for the person to realize that there is a complicacy in the muscle (symptoms such as a sore throat, muscle or joint pain, and headache) before it is visible. In this study, it is shown that by using the proposed fatigue model, a near identification of the presence of fatigue is possible. Biceps curl exercises with a dumbbell (7 kg) were used to develop fatigue in the biceps brachii muscle of the upper arm. In this work, four different feature sets were considered from sEMG signals and they were considered as an input to the dimensionality reduction method PCA and then the classifier SVM. sEMG signals were recorded from a total of 34 subjects (from 21 to 32 years). A classification success rate of 94.12% was achieved by using only two time-frequency features (average instantaneous frequency after Emphirical mode decomposition and total energy by using Wavelet packet transforms) as input to the proposed model. These results also show that fewer features can be used as an alternative to more features for differentiating between fatigued and healthy muscle using the proposed method.


It is shown that in an explosive system involving a single branching intermediate with normal temperature dependences both the classical (thermal and chain) critical conditions are supercritical. The chain-thermal critical condition is transformed into two forms, one suitably regarded as "iso-thermal perturbed by self heating" and the other as "thermal perturbed by branching reactions". The deviations from classical behaviour increase with pressure and ambient temperature.


Background:
 Although tobacco use, the majority of which is cigarette smoking, increases the risk of incident stroke, there are inconsistent data regarding the effect of tobacco use on neurological outcomes after acute ischemic stroke. Several prior studies have suggested that smoking could be protective after stroke, which has been termed the "smoker's paradox."

 Methods:
 We pooled three data sources to explore the effect of tobacco use on neurologic outcome in acute stroke patients. The first was the Blood Pressure after EVT in Stroke (BEST) study, the second was the NINDS tPA trial, and the third was the Interventional Management of Stroke (IMS) III trial. The primary outcome is 90-day mRS 0-2 (good outcome). We fit logistic regression models to good outcome, both unadjusted and adjusted for patient age, NIHSS, and sICH.

 Results:
 Our pooled cohort had 1,671 acute stroke patients, of which 480 (28.7%) used tobacco. In an unadjusted model, tobacco use was associated with good outcome (OR 1.42, 95% CI 1.15-1.76, p=0.001). However, in the adjusted model, this association was no longer significant (aOR 0.98, 95% CI 0.76-1.25, p=0.868). If we stratify by placebo-treated (n=310), tPA-treated (n=513), and EVT-treated (n=836), we continue to find that tobacco use is not associated with good neurologic outcome in adjusted analyses specific to these subgroups. An additional subgroup analysis of the EVT-treated patients that adjusted for successful procedural recanalization (TICI 2b-3) was not significant. Patients who used tobacco were younger (mean age, 60.5 vs. 69.2 years, p<0.001). Adjusting for age alone rendered the association between tobacco use and good outcome insignificant (aOR 1.05, 95% CI 0.84-1.32, p=0.666).

 Conclusions:
 This is the first adjusted analysis to examine the association between tobacco use and neurologic outcome in EVT-treated patients. We find that tobacco use is not protective after acute ischemic stroke that is untreated or treated with tPA or EVT. The univariate association of tobacco use with good outcome is accounted for by tobacco users being younger.


Dubrovnik was a cultural and the Serbian Primacy in Bar the religious centre of the Serbs Catholics. The newspaper Dubrovnik expressed the views of the Serbs Catholics. The owner, publisher and the editor was an old national activist Kristo P. Dominkovic, and main collaborators were Božo Hope and Jovan Perovic. The newspaper underlined that it followed Dositej Obradovic in his opinion that the ethnic origin and language were more important than religious affiliation. On June 15, 1939, on behalf of the Serbs Catholics, Luka Bone, Boyo Hope and dr M. Gracic from Dubrovnik sent to the archbishop in Bar and the Serbian primate, dr Nikola Dobrecic, a letter about the need to create the Serbian catholic theological school in Bar. They pointed out that the theological school was necessary both to the Serbian nation at the Coast and to the Catholics of the prewar Serbia, Montenegro and Vojvodina. Due to dr Nikola Dobrecic's endeavor, on June 20, 1935 the Archbishopric Seminary of the Serbian Primate in Bar was opened. In the Cvetkovic-Macek agreement from August 26, 1939, Dubrovnik was separated from the Zeta District (banovina) and allocated to the newly-created Banovina of Croatia. There began the persecution of the Serbs, the Yugoslavs and Yugoslav-oriented persons in Dubrovnik and its vicinity. The coup on March 27, 1941 caused great enthusiasm in Dubrovnik. Everything that happened in Dubrovnik and its vicinity, in Banovina of Croatia, was an introduction to everything that happened in The Independent State of Croatia. Those who ran away from the Croatian Ustashas took refuge in Boka Kotorska. .

The Action Plan is based on the multi-dimensional vision of the natural environment, the balance of nature, sustainable development and human care, in 2021, the Leopard Seal is listed as a first-class protected animal in the country. This paper expounds on the survival status of the spotted seal population by searching the judgments of criminal cases, administrative cases and on-the-spot investigation on the judgment network, this paper analyzes the main reasons for the endangered population of spotted seal and puts forward the corresponding protection countermeasures.


The World Health Organization policy statement on multi-dose vials states quite clearly that "the risk of contamination is higher in a multidose vial than in a single-dose vial because the vaccine is repeatedly exposed - every time a dose is withdrawn" (WHO 2000). In Australia, the 2004 Communicable Diseases Network Australia (CDNA) guidelines, approved by the Department of Health and Ageing state that "The Australian Drug Evaluation Committee advised that injectable products packaged in multi-dose vials should not be used, except where products such as insulin are intended solely for the exclusive use of an individual patient".


— Interest in voice control solutions has grown because of its potential for accessibility, ease of use and intuitiveness. For marketing reasons, technologies in this field are mainly focused on english speakers and resources for Brazilian Portuguese are still limited. Furthermore, many of it's services are dominated by large companies, whose solutions are highly priced, making it unaffordable for most of the brazilian population. This work aims to construct a low cost intelligent hub for home automation, entirely open source, interacting with the user through voice commands in Brazilian Portuguese. The prototype was built with Snowboy library for keyword detection, CMUSphinx tool for speech recognition and Home Assistant toolkit for devices integration. It was verified that the prototype meets the offline processing and command comprehension in the Portuguese language requirements, and has lower cost than consolidated platforms in the market.


I first introduce the early-stage and modern classical asset pricing and portfolio theories. These include: the capital asset pricing model (CAPM), the arbitrage pricing theory (APT), the consumption capital asset pricing model (CCAPM), the intertemporal capital asset pricing model (ICAPM), and some other important modern concepts and techniques. Finally, I discuss the most recent development during the last decade and the outlook in the field of asset pricing.


Clopidogrel bisulfate (CLP) form-I crystals are irregular, rectangular-shaped crystals. Because of their poor compressibility, flowability and their strong surface tension, manufacturers apply spherical crystallization methods to produce CLP form-I spherical agglomerates with a uniform particle size distribution. Consequently, manufacturers primarily synthesize CLP form-I crystal salts utilizing very complex methods, which produces form-I spherical agglomerates by means of spherical crystallization. In this study, spherical crystals of CLP Form-I were directly prepared from CLP Form-II, the most stable polymorph at room temperature, by using ethanol as solvent and a mixture of isopropyl alcohol (IPA)/n-Hexane (Hex) as an anti-solvent. To provide systematic inputs for the development of spherical agglomerates of optimal morphology, size, particle size distribution (PSD), and polymorphic form, processing parameters such as anti-solvent type, a mixture of IPA/Hex, pure Hex, or pure acetone; stirring speeds of 500, 600, 700, or 800 rpm; and temperatures ranging from 25 to 40 °C were explored. The effects of these parameters on spherical crystallization and polymorphic form were studied in terms of supersaturation, a driving force for polymorphic transformation, and the crystallization solution. Notably, our method does not require a large volume of anti-solvent which is the main complication of conventional anti-solvent crystallization methods.


Systemic Functional Linguistics,as the theoretical framework,is applied to the analysis of a text "Gettysburg Address"by Abraham Lincoln from the perspective of context of situation and cohesion.

After the introduction of outward development,it becomes much popular among students in high vocational colleges and is significant for students' developments.The outward development education makes up for the deficiency and inefficiency of the traditional athletic sports education in the mental health and the ability to adapt to the society.Also it reflects the modern people-oriented teaching idea.


Nanocrystalline nickel titanate (NiTiO3) composite powders were prepared by the sol–gel process combined with a surfactant-assisted template method. The resulting powders were calcined at different temperatures ranging from 150°C to 750°C for 2 h in air. The results revealed that a pure hexagonal phase of NiTiO3 could be obtained at the low temperature of 750°C. The phase evolution of NiTiO3 was investigated by X-ray diffraction patterns, Fourier-transform infrared spectroscopy, and X-ray photoelectron spectroscopy. Particle size and morphology were studied by transmission electron microscopy.


In the anterior cruciate ligament knee surgery reconstruction, autologous tendons graft remains as a main option as substitutive ligaments. However time effect on graft elongation is the main reason of ligament reconstruction failure. Traction tests have been performed on eight gracilis as well as on eight semitendinosus human muscles tendons obtained from four male cadavers at an average of 24.5 years. Each tendon specimen has been submitted to a deformation of 2.5% of its initial length for a time interval of 600 s with continuous recording of the corresponding force relaxation. The tendon specimen was then kept at rest for 300 s as soon as it returned to its initial length. The same specimen was then submitted to a similar test. Deformation rate for both tests was 10% of its initial length per second. Initial force values were obtained for resting time interval of 300 s as well as for 600 s. Statistical analysis suggests that the semitendinosus muscle tendon exhibits a more uniform mechanical behavior, as compared to gracilis muscle.


We consider f(R) gravity theories in the presence of a scalar field minimally coupled to gravity with a self-interacting potential. When the scalar field backreacts to the metric we find at large distances scalarized Schwarzschild-AdS and Schwarzschild-AdS-like black hole solutions. At small distances due to strong curvature effects and the scalar dynamis we find a rich structure of scalarized black hole solutions. When the scalar field is conformally coupled to gravity we also find scalarized black hole solutions at small distances.


A kinetic study on the effect of polysorbate 80 and sodium lauryl sulfate (SLS), on the photolytic degradation of flavin mononucleotide (FMN), was carried out through measurements of the electron spin resonance signal of the semiquinone, one of its intermediate degradation products. A plateau concentration of the semiquinone was first achieved with the aid of a constant light source. The decay was subsequently measured in the dark and was found to obey first-order rate of reaction. A comparative study of the rate of formation of semiquinone in the presence of polysorbate 80 and of SLS was then calculated from the plateau level and the decay rate constants in each condition. Both SLS and polysorbate 80 were found to accelerate the formation of the semiquinone derivative, then increase the rate of photodegradation of FMN.


The effect of abiotic parameters on the structure and dynamics of meiofauna in the environment of high temperature and salinity fluctuations has been studied. Samples were collected from six stations during one-year study in the shallow and isolated area of Velike Soline (Eastern Adriatic Sea, Croatia). A total of 12 taxa were found. The average annual density values of meiofauna range from 142.5 to 1740.75 individuals per 10 cm2. A negative correlation between total meiofaunal density and temperature and salinity fluctuations has been noted. Considering the structure of meiofauna we distinguished three zones: marine, transitional and lagoonal, which differ concerning the density and percentage of certain taxa, dominance pattern and habitat heterogeneity. No regularities in seasonal dynamics of the structure of meiofauna have been noted.


Since 1935, with the discovery of the phenomenon of quantum entanglement, unresolved questions and postulates have been generated, which have dismantled the basis of classical physics. Based on the reciprocal behavior of certain particles regardless of their distance, the existence of a state with a single-wave competence is assumed for the entire system, forcing us to accept new concepts such as non-locality and non-separability . Nowadays, creators are increasingly approaching the analysis of entanglement from different media, as a new source of inspiration and artistic research. In fact, the artistic platform is considered as a resource to spread this phenomenon, along with its theories and mysteries, familiarizing the viewer in one of the most defining manifestations for the progress of humanity.


The spectrum of iodine was photographed in the 300-200-A wavelength region on a 3-m normal-incidence spectrograph. The source used was a triggered spark. The previously reported analysis of I III was found to be completely erroneous. All levels of the ground state 5s 2 5p 3 and all but three levels of the three excited configurations 5s5p 4 , 5s 2 5p 2 5d, and 5s 2 5p 2 s have been established. 117 lines have been classified in this spectrum. Configuration-interaction calculations involving the 5s5p 4 , 5s 2 5p 2 6s, 5s 2 5p 2 5d, and 5s 2 5p 2 6d configurations describe the observed spectrum quite satisfactorily


im: 1) To analyze the effectiveness of various treatment methods for stasis dermatitis. 2) To evaluate the effectiveness of various components of conservative therapy. Methods: 80 patients (52 women and 28 men) aged 43 to 82 years old with CEAP class C4a varicose veins of the lower extremities, complicated by stasis dermatitis, were enrolled in the study. The patients were divided into two groups of 40 people each, comparable in terms of the main clinical and anamnestic data. The patients of the first group underwent surgical elimination of pathological reflux followed by conservative therapy. In patients of the second group surgical intervention was postponed or contraindicated. Patients of the second group were randomly divided into two subgroups of 20 patients using a random number generator. Patients of the second group received various options of conservative therapy. Results: In the first group, 34 patients (85%) showed complete remission of stasis dermatitis in the control periods, in 6 patients (15%) the area decreased to 11mm2. In subgroup 2A, complete remission was observed in 13 patients (65%). In the rest (7) the affected area was 13.8±mm2. In subgroup 2B, complete remission was not observed. The affected area averaged 14.1±mm2. Conclusions: The best result in the treatment of stasis dermatitis was observed in the group that received surgical treatment followed by conservative therapy. In two subgroups receiving conservative therapy, the subgroup treated with venotonics, showed the best clinical result. The study confirms the need for an integrated approach to the treatment of chronic venous insufficiency complicated by stasis dermatitis.


Urban habitat landscape is the important space and composition entities of human environment, which is formed a whole landscape by residents'life, exchanges, work and recreation and other related activities. It is a new field in urban human environment study. This article assesses the satisfaction of residents to urban landscape environment around themselves with expectation and perception theory and Visual Co-plot Version method, based on Nanguanling Street in Dalian. The results of the study indicate that there is a significant difference in residents'expectation and perception to habitat landscape, and the cognitive demand is increasing from street landscape to housing landscape.


Protecting water quality in the Great Barrier Reef World Heritage Area is recognised as one of the major challenges facing management of the area. One of the most important processes directly impacting the Great Barrier Reef (GBR) is the input of terrestrially derived nutrients and sediments to nearshore regions. This mainly occurs via river run-off, especially during periods of intense rainfall typically associated with tropical cyclones. Flood plumes occur at
a time when the majority of inputs into the GBR lagoon are at peak concentrations and reefs and other inshore marine ecosystems then experience the highest concentrations of
pollutants. The principal threat to the water quality of the reef arises from changes to the composition of the riverine discharge due to changed land use on coastal catchments. The
characteristics of the plume water, including salinity, nutrients, sediment and toxicants pose a range of potential threats to the health of inshore ecosystems.

Our increased understanding of airway inflammation in asthma has resulted in major breakthroughs in the treatment of patients. Following the introduction of anti-inflammatory inhaled corticosteroids in the 1970s, the introduction of biologicals that selectively neutralise the activity of, for example, IgE and interleukin-5, has been a major development in targeting inflammation in subgroups of patients with severe asthma [1]. The development of these biologicals required identification of targets for therapy and proof of concept intervention studies to establish the validity of these targets. This was the result of the combined power of clinical research in patients with asthma, as well as experimental studies using in vivo and in vitro models of the disease. This editorial discusses the value of various approaches and models to study asthma, and the need for an open-minded dialogue between basic, translational and clinical scientists to discuss potential discrepancies between findings in the various models. http://bit.ly/2m5ZvJo


Heavily available online data and its day to day expansion is need to be focus to store and retrieve it properly. This enforces the data owners tend to store their data into the cloud. This also suggest to handle the data properly and so release the burden of data storage and maintenance. But as the data owner and user, cloud server are not belong to same trusted domain, this may cause the outsourced to the risk. This enforce us to set the policy to avoid such risk factor. This gives us study scope to fine the different techniques to overcome such issue observed by different author. In this paper we try to underline the different solution, its limitation and results they achieved for retrieval of data securely and within less time. Definitely from this we will be able to propose our own solution.

This paper first proposes a novel framework for combining deep learning approach and Synthetic Aperture Radar (SAR) technique to evaluate and predict the condition of bridge displacement . The Long short-term memory (LSTM) neural network and the Small Baseline Subsets InSAR (SBAS-InSAR) are used to predict the longitudinal deformation of the bridge. Firstly, the proposed framework based on LSTM is established to obtain the relationship between the longitudinal deformation of the bridge and the influence parameters (such as temperature, temporal baseline, and others). In particular, the residual connection (RC) module is adapted to form the residual long short-term memory (Res-LSTM) neural network to improve prediction accuracy and robustness. A case study in Nanjing is analyzed to verify the performance of the proposed framework. The extracted datasets obtained from Sentienl-1 are divided into the training, validation, and testing dataset, which can satisfy the requirements in the engineering field. The R 2 and MSE of the testing datasets utilizing the proposed model are 93.17% and 15.62. Furthermore, the results indicated that the proposed framework based on Res-LSTM could predict and warn the abnormal structural deformation, extend the lifespan of structures, and minimize structural damage due to excessive deformation.


Zeolites represent a unique class of inorganic compounds, which have a simple idealized composition TO2 and uniform tetrahedral and bridge coordination of the T and O atoms. However, such simplicity gives rise to extremal diversity in the topologies of the zeolite frameworks, which is comparable with the variety of organic compounds: theoretically, the number of the framework topologies is infinite and the databases of hypothetical frameworks generated by computer procedures contain hundreds of thousands of entries. All the more surprising that the number of zeolites existing in nature or obtained in the laboratory is quite modest: currently, in the database produced by the International Zeolite Association there are only 248 topologically distinct zeolite frameworks, which compose less than 0.1% of the known low-energy hypothetical frameworks. Many efforts were undertaken to explain this phenomenon, as well as to predict new zeolite topologies. Paradoxically, most of the proposed explanations of this topological scarcity were based on geometrical or energetic properties of the frameworks, but not on their topological properties. However, low energy of the zeolite framework is not the sufficient proof of its feasibility; no less important are the kinetic factors that drive the framework assembly. While the framework energy is reflected to some extent by the geometrical parameters, which characterize the framework distortion, the assembly of the framework is encoded in its topological parameters. Thus geometry and topology meet to feature the thermodynamics and kinetics of the framework formation.


Job-shop Scheduling Problem (JSP) has become a hotspot for production management and combinatorial optimization research due to its high computational complexity. For the more complicated condition of JSP, how to achieve a short time to obtain the JSP optimal solution by designing the real-time and efficient strategy is still a problem in recent years. To solve this problem, a particle swarm optimization algorithm based on differential quantum properties is proposed. On the basis of quantum-behaved particle swarm optimization, variation, crossover, and selection operation are utilized by particles, which can better keep the diversity of the particles in the population, avoiding the local optimum in the later phase of the iteration. Multi neighborhood search is used for particles' local search to improve search precision. The operation-based encoding is firstly used to allow the research optimization algorithm for JSP solving. The results show that the research algorithm could achieve a short time to obtain the JSP optimal solution, the search precision and speed are improved obviously comparing with other algorithms such as the classical particle swarm optimization.


Introduction We know vaccine uptake varies by demographic group1. We considered behavioural associations between those who accepted vaccination and followed the social distancing guidelines. We compared those symptomatic patients with an acute sexually transmitted infection (STI) screens to those asymptomatic patients with a negative screen who may have been more likely to follow guidance and looked at STI rates. Methods We reviewed vaccine uptake amongst patients diagnosed with an acute STI, defined as chlamydia, gonorrhoea, mycoplasma, trichomoniasis, LGV, primary herpes and primary syphilis. The clinic electronic patient record, NHS Summary Care Record (SCR) and London Care Record were investigated retrospectively. Uptake was compared to asymptomatic patients with negative results. Vaccine uptake was compared between the two groups. Results 508 had acute STI, 388 had negative STI screens. 132/508 (27%) in acute STI group were fully vaccinated, and 132/388 (34%) in non-STI group. 2,408/14,424 (17%) had acute STI in 2019-2020, and 1,383/9,133(15%) in 2020-2021. There was a 2% drop in acute STI incidence. Discussion Vaccine uptake was higher amongst those the negative asymptomatic patients compared to those with acute STI. Only a small drop in acute STI was observed, suggesting sexual contact outside of social bubbles. Further analysis is needed to determine if patient behaviours predisposing to STI acquisition are associated with reduced vaccine uptake, which in part may be due to perception of COVID risk.

This study examined the perceptions of parents, teachers and children of the factors that influenced the literacy experiences, in particular of reading, of a group of Chinese children (ranging from nine to 11 years old) in their New Zealand schools. Participants included five Chinese families, recent arrivals in New Zealand who attended one urban co-educational primary school. Results indicated that the children responded positively to the New Zealand literacy learning context aided by effective teaching, the availability of engaging books, the support and expectations of the parents, the secure multicultural environment provided within the school, and the school's English for Speakers of Other Languages (ESOL) support. Children's motivation to read and their attitudes towards reading also contributed to their success at school. The participating parents and children were supportive of the New Zealand learning environment and approaches to literacy teaching and learning. The experiences of this group of children were positive and in some cases beyond the expectation of their parents. A brief picture of Chinese children maintaining literacy in their first language in New Zealand is also provided.


According to Reynolds equation and its boundary factors, the load-bearing capacity and the thickness of air cushion of the electromagnetic acoustic probe were worked out by using differential method and numerical integral. So obtained results could be used for computing the air cushion parameters in the gap of parallel plates with multi-hole gas supplying.


Turbulent flows at high Reynolds numbers are dominated by vortex filaments and/or sheets with sharp gradients in the vorticity field near the boundaries of the vortical structures. Numerical simulations of high Reynolds number flows are computationally demanding due to the fine grid required to accurately resolve these sharp gradient regions. In this paper, an alternative approach is proposed to improve the computational efficiency of Navier–Stokes solvers by reformulating the momentum equations as a set of equations for the time-dependent evolution of the flexion field. The flexion vector represents the curl of the vorticity field and is better able to resolve nonlinear effects in regions with large vorticity gradients. The improved resolution capabilities of the flexion-based approach are illustrated through the pseudospectral computations of the rollup of a perturbed 2D shear layer and the transition to a turbulence/viscous decay of the three-dimensional (3D) Taylor–Green vortex. The flexion-based formulation also provides further insight into the dynamics of turbulence through the evolution of the mean-square flexion or palinstrophy. Analysis of data from the Taylor–Green vortex simulations shows that the observed rapid growth of small-scale features and palinstrophy in 3D turbulent flows is primarily associated with flexion amplification by the curl of the vortex stretching vector. Consequently, we hypothesize that the primary physical mechanism responsible for energy cascade from large to small scales is the curl of the vortex stretching vector of interacting vortex tubes, as opposed to the stretching of individual vortex tubes.


Abstract The nature of the changes of physical properties of rubber resulting from oxidation processes is determined by its initial structure and also by the conditions of the process (temperature, concentration of reagents, extent of their interaction, type of reaction, etc.). In the interaction of molecular oxygen with linear polymers containing double bonds in the main chains, e.g., with natural rubber, a disintegration of the chains takes place in the initial stages, as a result of which an increase of solubility, a decrease of strength, an increase of plasticity and a decrease in the viscosity of solutions of the rubber are observed. The decrease in solubility and the increase of strength and elasticity set in at that stage of oxidation at which local links of ether type are formed between individual chains, or at which the accumulation of polar groups containing oxygen increases to a noticeable extent the intensity of intermolecular attractive forces. In the interaction of molecular oxygen with spat...

The objective of this study is to produce Pleurotus salmoneostramineus pink oyster mushroom using organic farming from some surplus local organic wastes, viz., the WSF1 formula (70 % wheat straw, 20 % woodworking sawdust, and 10 % date-palm fiber), the WSF2 formula (50 % wheat straw, 30 % woodworking sawdust, and 20 % date-palm fiber), the S formula (woodworking sawdust), the F formula (fibers of date-palm ( Phoenix dactylifera L.) trunk), and the W formula (wheat straw) as a control. The WSF1 formula gave the best yield and biological efficiency (163.2 g/bag and 45.5 %, respectively) with significant differences ( p < 0.05), while the S formula test recorded 27.8 g/bags and 6.5 %, respectively. However, F formula showed the highest number, reaching 35 basidiocarps in comparison to the control (wheat straw, 30 basidiocarps), followed by 28 basidiocarps with the WSF1 formula, whereas the S formula showed the lowest number of basidiocarps (6 basidiocarps). However, the WSF1 formula showed the best rate of basidiocarp weight (5.7 g) and diameter of pileus (9.0 cm). Significantly ( p < 0.05), the WSF1 formula showed a shorter length (11.9 mm), which was considered to be the best value in comparison with the control (19.5 mm). The S formula exhibited a low diameter of pileus (6.6 cm) and a longer stipe (18.6 mm), respectively. In conclusion, WSF1 is considered to be the best formula for the cultivation of this mushroom.

In this paper, we investigate properties of the generalized balancing sequence and we deal with, in detail, namely, balancing, modified Lucas-balancing and Lucas-balancing sequences. We present Binet's formulas, generating functions and Simson formulas for these sequences. We also present sum formulas of these sequences. We provide the proofs to indicate how the sum formulas, in general, were discovered. Of course, all the listed sum formulas may be proved by induction, but that method of proof gives no clue about their discovery. Moreover, we consider generalized balancing sequence at negative indices and construct the relationship between the sequence and itself at positive indices. This illustrates the recurrence property of the sequence at the negative index. Meanwhile, this connection holds for all integers. Furthermore, we give some identities and matrices related with these sequences.

Anti-phospholipid syndrome (APS) is an autoimmune disorder characterized by presence of anti-phospholipid antibodies (aPL) comprising lupus anticoagulant, anti-β2-glycoprotein I and/or anti-cardiolipin antibodies together with recurrent thrombosis and/or obstetric morbidity. In the course of COVID-19, thromboembolism may ocur due to endothelial dysfunction directly related to the viral factor and systemic inflammatory response. Concerns about COVID-19 vaccines began to arise after unexpected thromboembolic events were launched with the launch of vaccine campaigns around the world to prevent the disease.The purpose of the study is to contribute to the literature on this subject by evaluating the development of any side effects or activation of the disease after the COVID-19 vaccine in our APS patients.This study was designed as a cross-sectional, retrospective cohort study. The patients who meet the Sapporo Criteria for APS which are followed up in Ankara City Hospital Rheumatology Clinic, 18 years and over and vaccinated with any of the COVID-19 vaccines, were included into the study. The files of the patients were examined in order to evaluate the side effects and APS disease activation (thrombosis, embolism or pregnancy complications) in the 3-month period after the last dose of the COVID-19 vaccines (CoronaVac and BNT162b2). Also, information of the patients was collected via telephone or reviewed at regular follow-up visits.A total of 35 patients were included into the study (Table 1). In our patients, we did not observe any new thrombotic events or pregnancy complications during the 3-months observation period after COVID-19 vaccinations. The most common side effects after vaccinations were as follows; myalgia (30%), weakness (16.7%) and fever (10%) (Table 2). No patient became pregnant or gave birth during the follow-up.Table 1.Demographic and clinical characteristics of patients with Antiphospholipid antibody syndrome who received Covid-19 vaccineN=35Age, years, meadian (min-max)43 (28-63)Gender, female, number (%)33 (94.3)Active smokers, number (%)2 (5.7)Comorbidities, number (%) Hypertension6 (17.1) Chronic kidney disease2 (5.7) Sjogren syndrome2 (5.7) Diabetes mellitus0 Coronary artery disease0 Other4 (11.4)Time from diagnosis, years, median (min – max)7.0 (1.0 – 27.0)APS characteristics, number (%) Thrombotic APS22 (62.9)Cerebrovascular event11 (52.4)Deep vein thrombosis10 (47.7)Pulmonary thromboembolism2 (9.6) Obstetric APS21 (63.6)Treatment agents, number (%) Hydroxychloroquine28 (82.4) Acetylsalicylic acid16 (59.3) Varfarin16 (48.5) Corticosteroids15 (50)Adherence to APS drugs during vaccination32 (97)Table 2.Adverse events in vaccine recipientsBNT162b2CoronaVacPatients ever vaccinated with BNT162b2 or CoronaVac, n1715Dose per patient, median (min-max)2 (1-2)2 (1-3)Patients vaccinated with BNT162b2 or CoronaVac alone, n(%)17 (48.6)15 (42.9)Patients with an adverse effect after a dose of BNT162b2 or CoronaVac, n (%)6 (40)6 (50) Fever3 (18.7)0 (0) Malaise2 (12.5)4 (30.7) Local pain/arm pain2 (12.5)2 (15.3) Myalgia4 (25)4 (30.7)Patients with an adverse effect after 1stdose of BNT162b2 or CoronaVac, n (%) Fever00 Malaise00 Local pain/arm pain1 (16.6)0 Myalgia00Patients with an adverse effect after 2nddose of BNT162b2 or CoronaVac, n (%) Fever3 (20)0 Malaise2 (13.3)1 (14.2) Local pain/arm pain00 Myalgia4 (26.6)1 (14.2)Patients with an adverse effect after 3rddose of BNT162b2 or CoronaVac, n (%) Fever00 Malaise03 (50) Local pain/arm pain00 Myalgia03 (50)According to our results, no thrombotic events or pregnancy complications were observed after CoronaVac and BNT162b2 vaccines in APS patients.

Objective:To study the potential effects of heme oxygenase-1(HO-1)on the sensitivity of human gastric cancer cell line SGC7901 to 5-FU in vitro and the possible mechanisms involved.Methods:All cells were treated with various concentrations of hemin,ZnPP and 5-FU combination or alone at different times.The inhibition rate of cells was evaluated by MTT assay.Western blot was used for the detection of HO-1 expression.Flow cytometry was performed to detect cell apoptosis.ROS activity was examined by ROS colorimetric assay.Results:The application of ZnPP or 5-FU significantly inhibited the proliferation of human gastric cancer cells and the effect was dose-dependent.ZnPP(10 μmol/L)combined with 5-FU led to more inhibition and cell apoptosis than ZnPP or 5-FU alone(P0.05).On the other hand,hemin(10 μmol/L)markedly increased the resistance of SGC7901 cells to 5-FU-mediated cytotoxicity(P0.05).5-FU or hemin increased HO-1 protein expression compared with control group,and the increase was reversed by the use of ZnPP.The activity of ROS in 5-FU plus ZnPP group had a significant increase compared with other groups(P0.05),and the increase was reversed by the addition of hemin.Conclusion:ZnPP can enhance the chemosensitivity of SGC7901 cells to 5-FU,in which the inhibition of HO-1 expression and elevation of intracellular ROS activity may be involved.

A facile sol–gel-based method for the formation of monolithic polysilsesquioxane glasses from acid-catalyzed organotrimethoxysilane–water binary mixtures, free from alcohols and organic solvents, has been developed.


Novel materials, both monomeric and polymeric, were synthesised to study the non-emissive thermal rearrangement of N-cyanates. These materials undergo an exothermic rearrangement, at temperatures in the range of 150-300°C, to fused heterocyclic products. The series of N-cyanate polymeric materials was characterised by Fourier-transform infrared spectroscopy (FTIR) and modulated differential scanning calorimetry (DSC) as a preliminary assessment of their use as processable precursors to rigid rod polymers.


Objective To determine the feasibility and optimal design of a randomised controlled trial (RCT) of Seizure First Aid Training For Epilepsy (SAFE). Design Pilot RCT with embedded microcosting. Setting Three English hospital emergency departments (EDs). Participants Patients aged ≥16 with established epilepsy reporting ≥2 ED visits in the prior 12 months and their significant others (SOs). Interventions Patients (and their SOs) were randomly allocated (1:1) to SAFE plus treatment-as-usual (TAU) or TAU alone. SAFE is a 4-hour group course. Main outcome measures Two criteria evaluated a definitive RCT's feasibility: (1) ≥20% of eligible patients needed to be consented into the pilot trial; (2) routine data on use of ED over the 12 months postrandomisation needed securing for ≥75%. Other measures included eligibility, ease of obtaining routine data, availability of self-report ED data and comparability, SAFE's effect and intervention cost. Results Of ED attendees with a suspected seizure, 424 (10.6%) patients were eligible; 53 (12.5%) patients and 38 SOs consented. Fifty-one patients (and 37 SOs) were randomised. Routine data on ED use at 12 months were secured for 94.1% patients. Self-report ED data were available for 66.7% patients. Patients reported more visits compared with routine data. Most (76.9%) patients randomised to SAFE received it and no related serious adverse events occurred. ED use at 12 months was lower in the SAFE+TAU arm compared with TAU alone, but not significantly (rate ratio=0.62, 95% CI 0.33 to 1.17). A definitive trial would need ~674 patient participants and ~39 recruitment sites. Obtaining routine data was challenging, taking ~8.5 months. Conclusions In satisfying only one predetermined 'stop/go' criterion, a definitive RCT is not feasible. The low consent rate in the pilot trial raises concerns about a definitive trial's finding's external validity and means it would be expensive to conduct. Research is required into how to optimise recruitment from the target population. Trial registration number ISRCTN13871327
