using active and passive filters is necessary to prevent harmonic distortion of HVDC lines. This paper, using PHEVs in the case of (v2g) instead of the active filters capacitors by considering the stat of the charge of PHEVs battery is investigated. The main reason of using such an idea is that in the future, not so far, all fossil fuels cars are replacing by electric cars, which will lead to reduce air pollution and make cars more economical. However, providing ideas that lead to multi-purpose use of such vehicles is valuable in academic research and will significantly reduce costs to show the advantage of propose method the active filter has installed it in (HVDC) for human living.


A major river navigation project, the Paraguay—Parana Hidrovia, is being considered by the governments of Argentina, Bolivia, Brazil, Paraguay and Uruguay. The recently completed feasibility study for this project is seriously flawed and the errors systematically contribute to overestimating benefits and underestimating costs. The errors include overestimating the probability of a collapse in navigation, ignoring alternative forms of transportation, overestimating growth in regional shipments, omitting relevant construction costs, and perhaps most importantly, ignoring significant negative impacts to the environment. Correcting these errors, either individually or in concert, leads to the project not being economically feasible. Also provided is a method for including unspecified costs, such as those to the environment, in the analysis without further expensive and time-consuming studies.


Hierarchical linear models can separate variables of different spatial scales and different management levels,and they explain interactions between explanatory variables.This paper,taking Jiangsu province as a research area,uses hierarchical linear models to analyze the influence and mechanism of agricultural land use intensity and policy factors on grain yields.The results are shown as follows.(1) There are multi-level factors affecting grain productivity per unit area,agricultural land use intensity and policy factors separately explains 57.04% and 42.96% of differences in grain yields.(2) Grain productivity per unit area showed a rising trend from 2001 to 2008 in Jiangsu,of which labor intensity and capital intensity separately explained 19.50% and 5.68% of differences in average grain yield at county level.Land use intensity explained 25.17% of differences in average grain yield at county level,and intensive use of agricultural land is not the most important influencing factor that affects grain productivity,indicating that natural quality of land and land quantity has an increasingly important impact on grain production capacity.(3) Three policy variables-agriculture investment,technology investment and agriculture loans-have significant influence on grain yields.Agriculture investment only explained 11.90% of differences in average grain yields,and agriculture loans and technology investment separately explained 18.25% and 33.06% of differences in average grain yields.(4) All the selected policy variables can only explained 63.21% of differences in average grain yield at municipal level.


Abstract Factorial combinations of N, P and K fertilizer have been compared with the use of farmyard manure at Møystad since 1922 in a seven-year crop rotation (3 ley, oat, potato, wheat, barley). Until 1982, low inputs of N fertilizer (22 kg ha−1) were used. In 1983, they were brought into line with current farming practice. This paper presents the results of three subsequent rotations. Yields without any fertilizer were on average 48% of those with 100 kg N ha−1 in compound fertilizer, whilst those with 20, 40 and 60 Mg ha−1 farmyard manure were 81, 87 and 90%, respectively. Yields with other combinations of N, P and K declined in the order NP, NK, N, PK and K. When NPK fertilizer was used, apparent recoveries of applied fertilizer were close to 50% for N and K, and around 40% for P. Much lower values were found for nutrients applied singly. Balance between N supply and removal was indicated at rates of about 60 kg N fertilizer ha−1 in potatoes, 75 kg ha−1 in cereals and 90 kg ha−1 in leys. A surplus of P was found in all crops at all N levels, and of K in cereals and potatoes. In leys, K balance was achieved with an N supply of 90 kg N ha−1. Nutrient balance was indicated at a little below 20 Mg ha−1 yr−1 farmyard manure. Larger manure applications gave large nutrient surpluses, particularly of N. Soil reaction remained close to neutral with the use of calcium nitrate and manure, but declined with the use of ammonium nitrate. Manure use gave the highest amounts of available P, K and Mg in soil. Similar increases in total inorganic P were found with manure use as with fertilizer use, but amounts of organic P and total K were little affected.


In order to research forces on a plough head and load characteristics of a plough, mathematic models of random loads on plow tools at different locations on a plough head are presented by using theory of stochastic process and probability statistics. Random loads are simulated and studied with a prepared computer program, then the changing regularity of random load on plow tools at different locations and its statistical values are obtained. Results show that the magnitude of means of planing forces, feed forces and lateral forces on plow tools at different locations are in the following order: middle plow tool 、slotting plow tool、top plow tool、foot plow tool. The planing force, feed force and lateral force on foot plow tool are 3.41, 3.42 and 1.47 times compared with those on middle plow tool. Variation coefficients of the three forces on foot plow tool are 0.58245 、0.33081、0.20653, so it has the largest load fluctuation and is seriously damaged. These simulation results match with the fact, which proves the research method practical and feasible and provides a theory basis for studying the load spectrum on plow head and plough.

Protected areas (PAs) are inviolate and invaluable landscapes that promote the in situ conservation of endangered, threatened and rare species. Accordingly, and in keeping with this definition, PA managers ensure that PAs are free from fire, poaching, grazing, non-timber forest products collection, mining, etc. In India, following the Indian Wildlife (Protection) Act (1972), there are today 102 and 515 National Parks and Wildlife Sanctuaries respectively. Many of these have in recent decades been heavily threatened by the spread of invasive alien plant species, notable among them being Lantana and Eupatorium. These species may have usurped as yet unestimated number of native plants and fauna, besides depressing the reproduction of native plant species. In
fact, it is realized that the threat to biodiversity by invasive alien species (IAS) may only be second to that of fragmentation. Yet there seems to be no major attempts to eradicate, contain or manage IAS in PAs. Ironically, the justification for the lack of action lies in the definition of PAs – that they need to be kept inviolate and therefore above any active intervention. In this article we bring home this serious contradiction in the approach to management of PAs in India and discuss the philosophical origins of this practice. We argue that if we are to protect our PAs from the serious scourge
of invasive species, we would have to relook at the policy governing PA management and revise it to be more inclusive than exclusive.


Abstract Organic biodegradable waste composes a fair part of farm and vital activity waste. The disposal of this waste in municipal waste landfills pollutes the environment and soil. Therefore, the European Union and other countries look for alternatives to manage biodegraded waste. This paper seeks to analyse the properties of sludge that forms in the sewage treatment plants of the acid casein production, examines experience in managing and applying sludge. The results of an experiment show that sewage sludge from the acid casein production is suitable as a soil fertilizer for growing lettuce (Lactuca sativa L.) and garden cress (Lepidium sativum L.). After soil was fertilized with this sludge, the germination of lettuce and garden cress as well as the biomass of experimental alimentary plants increased. A suitable ratio of soil and sludge mixture was determined (for lettuce ‐ 1:1, for garden cress ‐ 3:1). Potassium sulphate which was added to a soil‐sludge mixture improved the values of fertility parame...


Summary. Milk production and composition was determined in Holstein-Friesian cows fed either 3.5 or 7.0 kg dry matter (DM) daily of lupin grain, pea grain, faba bean grain or barley grain with or without 1.5% added urea, as supplements to an oaten hay based diet. All the grains were hammermilled. Daily yields of milk (L), fat (kg) and protein (kg) were significantly (P<0.05) higher for cows fed lupin (20.0, 0.81, 0.57), pea (18.9, 0.80, 0.56) and faba bean (18.9, 0.79,0.55) grains compared with those of cows fed barley grain with (17.8, 0.73, 0.51) or without (18.0, 0.71, 0.52) urea. Yields of milk (L), fat (kg) and protein (kg) and milk protein content (gikg) were significantly (P<0.05) higher when 7.0 kg DM (19.5, 0.80, 0.57, 29.6) compared with 3.5 kg DM (18.0,0.73,0.51,29.0) of grain was fed. There were no significant differences between treatments in hay DM intake by cows fed 3.5 kg DM of grain daily. A significantly (P<0.05) higher milk fat production per unit DM intake was recorded for cows fed legume compared with barley grain. There were generally higher returns above grain cost for cows fed legume compared with barley grain and for cows fed 4 kg compared to 8 kg daily of grain. It was concluded that it was more economical to feed 3.5 kg DM of legume grain compared with 3.5 kg DM of barley grain, with or without urea, as supplements for cows offered cereal hay in early lactation. However, the economics of feeding 7.0 kg DM of legume grain compared with 7.0 kg DM of barley grain and 7.0 kg DM compared with 3.5 kg DM of grain will depend on the costs of relative changes in hay intake associated with these practices.

The mechanical behaviour of artificially cement-treated Babolsar sand reinforced with sack, polyethylene terephthalate (PET) and polypropylene (PP) fibres is studied in this paper. Tests were conducted on cemented sand samples prepared at a relative density of 70%, with and without reinforcements on direct shear and triaxial apparatuses. Effects of parameters such as fibre content (FC), fibre type and normal or confining pressure (NP or CP) have been studied. Test results revealed that the addition of fibres had a significant effect on the behaviour of cemented sand. However, PP fibres are much more effective reinforcing materials than sack and PET fibres. A comparison between the results of direct shear tests and triaxial tests indicated that the fibre efficiency and its effect on soil behaviour is much more significant in triaxial tests compared with those in direct shear tests.


The physionomy of an Imperial Roman private garden has

The major contradict confronted in China's economic teaching and research is that between the high requirement of the practice of socialism market economy and the relative low level of economic teaching and research. The correct issue, therefore, is how to establish economics theory to fit to the practice of the socialism market economy based on the guideline of Marxism economics. The key of this process is to stick to the developing Marxism economics as the guideline of China's economics and the core is to logically combine the Marxism economics and the useful part of western economics together.


This paper presents the results of a study designed to gather information on communication between an accounting firm and its clients. We first provide descriptive information on clients' perceptions regarding the frequency, method, and importance of communication with their accounting firm. We then provide evidence on the relationship between effective communication and both client satisfaction and accounting firm/client conflict. We find that that the use of effective communication techniques by an accounting firm is positively related to client satisfaction and negatively related to firm/client conflict. The overall results of this study suggest that accounting firms can effectively use collaborative communication, which focuses on using communication to build better relationships between firms, to manage client relations.


I t has been reported earlier that a certain relation exists between the glycogen content of the foetal heart and the ability to survive under anoxia. No definite conclusions can, however, be drawn from the results of experiments published hitherto. Moreover, it has been shown that impaired nutrition in the mother decreases the glycogen content of the foetus by up to 40 %. The object of the investigations was to elucidate the following questions: 1. The possibility of increasing the heart glycogen content in the foetus by glucose infusion in the mother before delivery. 2. The extent to which the heart activity can be prolonged under anoxia by an increase in the glycogen content of the heart muscle. 3. Ultrastructural changes in the heart muscle associated with heart activity under anoxia. 4. Changes in the electrolyte concentrations in the plasma and heart muscle during heart activity under anoxia. The investigations were made in rabbits. About half of the animals served as controls. On the 29th day of pregnancy (the duration of pregnancy being 31 days), a rabbit was given an infusion of 120 ml of 30 % glucose solution in the course of 6 hours (9 g/kg body weight). Immediately after the infusion the rabbit was sacrificed and, as a rule, a control as well. The abdomen was opened. One foetus from each litter was immersed in a container with liquid paraffin (37O C ) , and the ECG was recorded under anoxia. At


Application of bacteriophages and their lytic enzymes to control Clostridium perfringens is one potential approach to reduce the pathogen on poultry farms and in poultry-processing facilities. Bacteriophages lytic for C. perfringens were isolated from sewage, feces and broiler intestinal contents and CPV1, a virulent bacteriophage, was classified in the family Podoviridae. The purified virus had an icosahedral head and collar of approximately 42 nm and 23 nm in diameter, respectively, with a structurally complex tail of 37 nm lengthwise and a basal plate of 30 nm. The CPV1 double-stranded DNA genome was 16,747 base pairs with a GC composition of 30.5%. Twenty-two open reading frames (ORFs) coding for putative peptides containing 30 or more amino acid residues were identified and analyzed in the genome. Amino acid sequences of the predicted proteins from the CPV1 genome ORFs were compared with those from the NCBI database and potential functions of 12 proteins were predicted by sequence homology. Three oultry ood-borne illness acterial virus putative proteins were similar to hypothetical proteins with unknown functions, whereas seven proteins did not have similarity with any known bacteriophage or bacterial proteins. Identified ORFs formed at least four genomic clusters that accounted for predicted proteins involved with replication of the viral DNA, its folding, production of structural components and lytic properties. One bacteriophage genome encoded lysin was predicted to share homology with N-acetylmuramoyl-l-alanine amidases and a second structural lysin was predicted to be a lysozyme-endopeptidase. These enzymes digest peptidoglycan of the bacterial cell wall and could be considered potential therapeutics to control C. perfringens.


Recurrent neural networks can be large and compute-intensive, yet many applications that benefit from RNNs run on small devices with very limited compute and storage capabilities while still having run-time constraints. As a result, there is a need for compression techniques that can achieve significant compression without negatively impacting inference run-time and task accuracy. This paper explores a new compressed RNN cell implementation called Hybrid Matrix Decomposition (HMD) that achieves this dual objective. HMD creates dense matrices that results in output features where the upper sub-vector has "richer" features while the lower sub vector has "constrained" features". On the benchmarks evaluated in this paper, this results in faster inference runtime than pruning and better accuracy than matrix factorization for compression factors of 2-4x.


The relationships between parental smoking and the rates of lower respiratory illness during the first three years of life were examined for a birth cohort of 1265 New Zealand children. Lower respiratory illness varied significantly with maternal smoking for the first year; there was equivocal evidence of a relationship between maternal smoking and lower respiratory illness in the second year; and by the third year the relationship had clearly disappeared. Paternal smoking had


In the title compound, [Zn(C17H16N2O2)(H2O)], the ZnII atom has a distorted pentacoordinate square-pyramidal geometry. A mirror plane passes through the ZnII atom, the central C atom of the propyl group and the O atom of the coordinated water molecule. The two planar Schiff base groups make a dihedral angle of 39.49 (6)°. The crystal packing is stabilized by weak intermolecular interactions via the coordinated water molecule.


Randomness is inherent to biochemistry: at each instant, the sequence of reactions that fires is a matter of chance. Some biological systems exploit such randomness, choosing between different outcomes stochastically - in effect, hedging their bets with a portfolio of responses for different environmental conditions. In this paper, we discuss techniques for synthesizing such stochastic behavior in engineered biochemical systems. We propose a general method for designing a set of biochemical reactions that produces different combinations of molecular types according to a specified probability distribution. The response is precise and robust to perturbations. Furthermore, it is programmable: the probability distribution is a function of the quantities of input types. The method is modular and extensible. We discuss strategies for implementing various functional dependencies: linear, logarithmic, exponential, etc. This work has potential applications in domains such as biochemical sensing, drug production, and disease treatment. Moreover, it provides a framework for analyzing and characterizing the stochastic dynamics in natural biochemical systems such as the lysis/lysogeny switch of the lambda bacteriophage.


The study investigates a general hypothesis regarding the bases of certain reading disabilities: poor readers suffer from an impaired rate of auditory processing [P. Tallal, Brain Lang. 9, 182–198 (1980)], such that they are unable to discriminate or detect the order of a pair of brief complex tones at short interstimulus intervals. Such children also had difficulty with two synthetic speech sounds, /ba/ and /da/, on analogous tasks, which was similarly attributed to a deficit in the processing of rapid acoustic changes, such as those which occur in formant transitions signaling place of articulation in stop consonants. The present study, in establishing the significantly lower performance by poor readers, compared to good readers, with /ba/ and /da/, at short interstimulus intervals (100, 50, and 10 ms), however, failed to show any significant difference between the groups when the acoustic‐phonetic contrast of the stimulus pair to be discriminated was increased, as with /ba/–/sa/ or /da/–/(sh)a/. Furthe...


Encapsulated in a protective [{Fe(pz)3 }4 ] outer layer, which provides the complex with structural stability, the octanuclear complex [Fe8 (μ4 -O)4 (μ-pz)12 Cl4 ] contains a Fe4 O4 core (see drawing) that withstands four consecutive reversible one-electron reductions. Iron-oxygen clusters are shown to possess redox properties which rival those of their better studied iron-sulfur analogues. pz=pyrazolate anion.


Coalescent petrositis is an uncommon condition and is now most commonly observed complicating chronic, antibiotic resistant ear infections. Tomography defines areas of bone destruction which are equivocal on conventional views. Four cases are presented which demonstrate accurate localization of the petrositis by tomography, providing preoperative assessment of the approach and extent of the necessary surgical procedure.


Some Beyond the Standard Model theories predict new particles that decay predominantly into top-antitop quark pairs. A search for top-antitop quark resonances that decay into the lepton plus jets final state is carried out with the ATLAS experiment at the LHC using 14 fb$^{-1}$ of $\sqrt{s}$ = 8 TeV proton-proton collisions. The search considers both cases where all of the final state jets are isolated and where some or all of the top quark decay products are merged into a single jet. Mass exclusion limits at a 95% credibility level are set for two benchmark models, one predicting leptophobic topcolor Z' bosons and the other predicting Randall-Sundrum Kaluza-Klein gluons.


This paper deals with the application of digital signal processing in power electronics and power systems applications. Particularly, it abords the design and implementation of low frequency digital filters or controllers under high sampling rates. Special attention is deserved to the quantization problems on discrete systems using fixed-point digital signal processors (DSP). An improved solution for digital processing using the unusual /spl gamma/-transform instead of the conventional Z-transform is considered. Since it is very frequent to use some kind of tuned filter in the mentioned applications, the discussion has been directed to the implementation of practical digital filters. Simulations and experimental results using a 16 bits DSP illustrate the superior performance of delta digital filters in open or closed-loop systems.


Let Mn be the C*-algebra of n × n complex matrices. If A is a C*-algebra, let Mn (A) denote the C*-algebra of n × nmatrices a = [aij] with entries in A. For a linear map between C*-algebras, we define the multiplicity map by A linear map Ø is said to be completely bounded if Let B(A, B), CB(A, B) denote the Banach space of bounded linear maps, the set of completely bounded maps from A to B, respectively.

The the is deep to it. Thus, it is difficult to investigate its characteristic. To understand the characteristics of the deep active fault (i.e., plate interface), we use P- and S-wave velocities (Vp, Vs) of the digital rocks extracted from outcrop of ancient plate boundary fault at Nobeoka in Kyushu, southwest Japan. By comparing the elastic properties derived from digital rock with seismic velocity (e.g., Vp/Vs) acquired around the in situ seismogenic fault, we characterize the deep seismogenic fault. We extract 3D digital rock models with the size of 5mm x 5mm x 5mm from 3D micro-CT images. By using Finite Difference Method (FDM), we perform the dynamic wave propagation simulation and measure the effective Vp, Vs, and ratio of P-and S-wave velocities (Vp/Vs) of 3D digital rock models. Moreover, using this approach, we can identify the heterogeneity, which strongly influences to the seismic velocity. Here, we investigate the sensitivity of Vp and Vs to crack-filling materials. The heterogeneous texture, such as fracture or pore space was identified based on comparison of the density and porosity from digital rock model with the average of porosity from laboratory measurement. We can measure Vp and Vs for heterogeneity texture with any fracture-filling materials by replacing the pore space with dry, water saturated and mineral filling (quartz and calcite) conditions. The results demonstrated that the pore space in the dry and water saturated conditions significantly decreases velocity. The Vp/Vs ratio of water saturated case (Vp/Vs=~1.84) is higher than dry condition (Vp/Vs=~1.75). In the mineral-filling model (quartz and calcite),


During the years 1992–1998 at Penn State, I collaborated closely with Ralph Goodman on scattering from the near‐surface oceanic bubble layer. Ralph's enthusiasm, physical insight, and encyclopedic knowledge of at‐sea experiments proved to be invaluable. I will outline the research and discuss Ralph's contributions to graduate theses and scientific papers that were published. I will also give some personal observations on what it was like collaborating with Ralph.


Learning achievement is a benchmark as a result of students' achievements during the learning process. Success in learning is inseparable from the media used as well as a strong willingness to learn. This research aims to analyze the influence of learning media usage and learning motivation on students' learning achievement. The analysis used is a quantitative approach to multiple linear regressions. Data is obtained from observations and questionnaires. The results of the analysis showed that the use of learning media and learning motivation had a positive and significant effect on learning achievement. Thus, the conclusion to achieve maximum achievement needs to be optimized the use of learning media as well as stimulate the motivation of students both motivation from within and external motivation


In laboratory experiments with resting and germinated seeds of spring wheat, the effect of various biological preparations on the activity of catalase isoforms was studied. In the experiments, the activity of catalase isoforms was determined at pH = 5.5, 7.0, 8.0 using a phosphate buffer system (1/15 M phosphate buffer). The activity of catalase enzyme isoforms was determined in dormant wheat grain that underwent post-harvest ripening and during germination on the third, fifth, and seventh days using a method based on determining the amount of hydrogen peroxide dissolved under the action of the enzyme, and subsequent titration of the remaining undissolved hydrogen peroxide with potassium permanganate. In experiments, the effect of the following biopreparations protective and stimulating complex (PSC), Hardy, Ferovit and Ferovit+Hardy mixture, which were applied by foliar treatment during cultivation of wheat plants, was investigated. It has been established that changes in the activity of catalase isoforms occur both in dormant and germinating plant seeds and differ depending on the biological preparation used in plant cultivation.


The devices that constitute the Internet of Things are evolving to include more than just enabling sensing and actuation over a wireless interface. In a contemporary scenario, these devices perform tasks and contribute to an aggregate information flow, in a distributed manner. In the wake of this evolution, new distributed Internet of Things frameworks have emerged. These frameworks maintain a distributed shared state in a distributed hash table. An Internet of Things system's ability to make decisions autonomously and distributively depend on the level of consistency of the shared state. As wireless resources are scarce, the amount of deferred state information in each device is unknown when the system is highly utilised. In this paper, we have developed a controller with the objective to achieve a bounded time-average of deferred state information in each device while maintaining system stability. The controller is derived using Lyapunov drift optimisation with penalty. The resulting controller can successfully bound the shared state consistency level within a narrow margin, maintain system stability, and balance the traffic flow trade-off more successfully than comparable and conventionally used methods.


Abstract Polymer is popularly used for the housing or parts of machine and equipment. However, the mechanical properties, especially the fracture process has not been clarified. It is the reason why polymer has not been used for the parts required reliability By the way, it is well known that fracture process of polymer under monotonic tensile test occurs Molecular chains locally orient in a very fine area, then the area grow up with increasing load and strain. The grown up area is called "craze". After then, the craze grow up and coalescent each other, and the fibril is broken in some craze and becomes micro crack. However, we can only monitor the craze optically, and it is difficult to monitor the precursory stage of craze dynamically In this paper, the precursory stage of craze during tensile test was monitored by ETFuM (Elastic-wave Transfer Function Method), and evaluated quantitatively. In this study, clarification of the relation between mechanical degradation process and the transfer function in P...


myocarditis apparently due to chronic lead poisoning in childhood. Pollution of water has frequently been considered a source of lead poisoning and recently Wetterberg (1966) has suggested that the high lead content of locally-caught fish might be responsible for the high incidence of acute symptoms of porphyria in Swedes living along the borders of the Skellefte river, an area which is known to have a high genetic incidence of acute porphyria. On page 73 of this issue of the Scottish Medical Journal, Dr Wilson has described his experience in Innerleithen where it was found that the water supplies intermittently exceeded the present WHO standard limit for lead content. This high level of lead in the water was due to the state of the lead piping and also to various changes in climatic conditions. Wilson used a simple Donath apparatus which detects excess coproporphyrin in the urine, as a screening test. Lead poisoning in women has for many years been associated with abortion and he was particularly interested in the possible effects of the contaminated water on pregnancy. For this reason he compared the urinary coproporphyrin levels in 35 pregnant women in his practice with those of 404 other hospital antenatal patients. Only 2 per cent of the hospital patients outside Innerleithen had increased coproporphyrin levels while 31 per cent of his Innerleithen patients had increased levels. One stillbirth from a series of 75 pregnancies gave evidence of abnormal exposure to lead since there were increased foetal kidney levels of lead and an elevated maternal blood lead level. One patient who had a particularly unsatisfactory water supply had miscarriages or antepartum haemorrhages in 7 out of 8 pregnancies. While such a trial carried out under difficult conditions in general practice must inevitably lack the scientific data essential for a sophisticated statistical study, it is sufficiently conclusive to point to the dangers of lead contamination of water which are still present in Scotland today. It will give particular satisfaction to members of our profession in Scotland that Dr Wilson gained the Sir Charles Hasting Clinical Prize of the British Medical Association of 1963 for his work, which also demonstrates


Acid upland is considered a potential area for horticulture crop such as cayenne pepper (Capsicum frutescens L.). This study aimed to evaluate the effects of the use of cacao shell biochar and compost to soil properties and the productivity of cayenne pepper in acid upland. This research was conducted in Taman Bogo research station, Lampung Province, Indonesia in 2017. This research used a randomized block design with seven treatments and three replications. The treatments consisted of P0: control (no soil ameliorant and mulch), P1: biochar 20 t ha−1, P2: P1+ mulch, P3: compost 20 t ha−1, P4: P3+mulch, P5: biochar+compost (1:1) 20 t ha−1, and P6: P5+mulch. The raw material of biochar was cacao shell, while compost was manure. The result showed that soil bulk density of biochar, compost, and a combination of biochar and compost treatment lower than control. Biochar with and without compost have soil water content higher than other treatments. Moreover, biochar with and without compost were increase pH, reduce exchangeable Al level, increase C and N content also increase cation exchange capacity (CEC) and base saturation. The use of biochar and compost had positive effects on plant height, the diameter of canopies, and crop yields.


The use of licit and illicit drugs is a phenomenon that is continually changing and manifests differently in population groups. The historical evolution of consumption in the world, has shown that young people constitute the most vulnerable group to initiate and develop addictive behaviors with physical, psychological, emotional and social implications of relevance in our society. Drug use among students of the institution, tends to follow the behavior reported in other university contexts; however, it is a phenomenon subject to constant changes that motivate the investigative persistence, for both prevention and intervention decisions must conform to current panorama diagnosis in each stage of consumption. Objective: To describe the use of licit and illicit drugs in students from a Higher Education Institution. Materials and Methods: A descriptive cross-sectional quantitative study, the product of a collaboration agreement with the University of Veracruz (Mexico). Stratified random sampling for a population size of 5205 undergraduate students was conducted. The information was collected from 573 students; the instrument used is CODEU designed by Beverido et al in 2012, as a result of an authorized adaptation of a 2007 UNAM Student Questionnaire designed by Villatoro et al (2007). Results: The prevalence of life for the consumption of psychoactive substances (SPA) reported as the highest in the study are, in descending order of alcohol 94%, energy drinks73%, marijuana 19%. The lower prevalence of hallucinogens life is 7%, tranquilizers 5%, amphetamines 3%, cocaine 3%, methamphetamine 1%, inhalants 1%, bazuco 0.2%; no heroin was reported.


Natural antioxidants have gained considerable interest for their role in the prevention of autooxidation of fats and oils. Larrea divaricata Cav. is a South American plant widely distributed in Argentina with reported antioxidant, antitumoral and antimicrobial activities. The aqueous extract of the plant exerts antioxidant activity preventing the deleterious effect of temperature and oxygen on the antioxidant activity of vitamin C (Vit C). The aim of this work was: to assess the stability of the aqueous extract of L. divaricata (AE) under different environment conditions, such as different temperatures and air oxygen contents. The stability parameters evaluated included the percentage of majority compounds (flavonoid expressed as quercitrin (F) and nordihydroguaiaretic acid (NDGA)) and the antioxidant activity of the extract (AC). Results indicated that both compounds were affected by temperature and air oxygen, with F being more stable to high temperatures than NDGA, finding a decrease of 56% for F and a decrease 66% for NDGA. Nevertheless, NDGA was more sensitive to air oxygen, as an early decrease of 62% and a maximum decrease of 100% were found. The AC of AE decreased with high temperatures; however, air oxygen seemed to have a more important effect, for a decrease of about 42% was observed after 7 days of incubation. Even though, the environment conditions could affect the chemical composition of the whole extract, it was observed that not all the compounds were equally affected by temperature and air oxygen. Reaching a balance between these two parameters could allow a modulation of the antioxidant activity of this extract. _____________________________________________________________________________________________________________


Introduction: High-grade dural arteriovenous fistulas (DAVFs) with retrograde cortical leptomeningeal drainage are formidable lesions because of their risk for intracranial hemorrhage. Treatment is aimed at occluding venous outflow to achieve obliteration of the fistula. In DAVFs that involve a large dural venous sinus, occluding venous outflow can be accomplished endovascularly with transvenous embolization. In cases of DAVFs with reflux into cortical leptomeningeal veins, there is usually venous restrictive disease downstream that can prohibit endovascular access via the transfemoral or transjugular routes. Methods: In this study, we describe our technique of surgically assisted transvenous embolization in three patients with high-grade DAVFs involving a large dural sinus with retrograde cortical leptomeningeal drainage. Results: Surgically assisted transvenous embolization of the DAVF resulted in complete angiographic obliteration in all three patients on postembolization angiography. All had improvement of their preoperative symptoms, and there were no recurrences and no further clinical events after a mean follow-up of 37 months. There were no complications of venous hypertension or venous infarction. Conclusion: Our technique is unique in that the craniectomy and embolization procedures are performed as a single stage in the operating room with intraoperative angiography and stereotactic image guidance. In these instances, a transcranial approach can be performed to expose the large dural venous sinus distal to the site of occlusion for direct catheterization of the venous outflow for transvenous embolization. This combined surgical and endovascular strategy provides direct access to the venous outflow and bypasses the site of thrombotic obstruction.


This paper describes the evaluation of characteristics of meander type heat elements for facsimile thermal printing heads. Mainly rectangular type heat elements have been used for this purpose to date. However, they have some inherent weak points, such as difficulty in obtaining a uniform temperature distribution in a desired heating region and difficulty in obtaining a resistance value suitable for driving them. the authors have manufactured samples of meander type heat elements and investigated them mainly from the point of view of their applicable range and reliability. It is known that (1) in meander type heat elements, if the thickness of the element is greater than a certain value and if the elements are covered with protective layers, the elements withstand heat pulses independently from the thickness of the elements. This also prevents the deterioration of elements due to oxidation. (2) the protective layer on a meander type heat element has greater resistance to thermal shock and better printing characteristic than those of a rectangular type heat element. (3) the meander type heat element does not cause local fusion in the heat insulation layer because of uniform heating. Therefore, this has a higher reliability over a wide range of driving pulse widths. (4) the meander type heat element is inherently superior to the rectangular heat element and will make a greater contribution to improvement of the quality of thermal printing.


From 1999 to 2022, ethnic affiliation, religiousity and geo-political zones has been the unofficial pre-election criteria for selecting candidates for the presidential and governorship positions in Nigeria. The selection process created unnecessary tension in the polity. To stem the tide of political volatility, there has been intensification in calls for zoning principal offices between the north and the south, and between the various senatorial zones at the state level. In revisiting the politics surrounding zoning, and the questions about its constitutionality, the paper examines its historical antecedent, as well as Article 72(C), 2009 of People's Democratic Party's Constitution. Adopting Elites theoretical framework, and for methodology, qualitative descriptive data and content analysis was utilized. The paper found that intra-elite rivalries and the 'do or die' politics during the process of selection and election of candidates, has marred the development of democratic ethos in the country. It concluded that due to the above anomalies, democracy has faced some dysfunctionality, giving rise to the quest to zone principal offices. Considering Nigeria's multi-ethnic diversity, the study recommends that before its adoption, the National Assembly should constitutionally spell out the modalities for its operation, as it stands out to be a more peaceful means for achieving equity and inclusiveness in governance.


Reaction of protactinium solution 2.99 x 10/sup -4/ M in 0.1 n HCl containing 0.01 M NH/sub 4/F with chlorophosphonazo(III) (3,6-bisSTA(4-chloro-2- phosphonophenyl)azo! -4, 5-dihydroxy2,7-naphthalenedisulfonic acid) resulted in a blue-green compound. The absorption curves of chlorophosphonazo (III) with Pa(V) are constructed and the maximum absorptions for Pa compounds are found at 630 and 688 m . The Pa compound spectrum is closer to the Np(IV) and Th(IV) spectra than to Np(V) and U(VI). The experiments indicate that arsenazo III and chlorophosphonazo III behave identically. (R.V.J.)


The effect of rail corrugation on the vertical dynamics of railway vehicle coupled with a curved track is investigated in detail with a numerical method when a wheelset is steadily curving. In the calculation of rail corrugation we consider the combination of Kalker's rolling contact theory modified, a model of material loss on rail running surface, and a dynamics model of railway vehicle coupled with a curved track. In the establishment of the dynamic model, for simplicity, one fourth of the freight car without lateral motions,namely a wheelset and the equivalent one fourth freight car body above it, is considered. The Euler beam is used to model the rails and the track structure under the rails is replaced with equivalent springs, dampers and mass bodies. The numerical results show the great influence of the rail corrugation on the vibration of the parts of the vehicle and the track, and the some characters of rail corrugation in development.

The present paper presents descriptions of 11 trepostome bryozoan species from the material deposited at the Geological Centrum Gottingen, Germany, and Nationaal Natuurhistorisch Museum (Naturalis), Leiden, Netherlands. The studied material comes from the Lower to Middle Devonian (Emsian-Eifelian) deposits of different localities in Cantabrian Mountains, NW Spain. Three species are new: Leptotrypella maculata n. sp., Anomalotoechus tabulatus n. sp. and Eifelipora tenuis n. sp. The genus Mongoloclema is reported for the first time from the Devonian of Europe. The described fauna displays palaeobiogeographic relations to the Lower Devonian (Pragian) of Bohemia and to the Middle Devonian of Kazakhstan and Michigan (USA).


About a decade ago, the discovery of monolayers of transition metal dichalcogenides opened a new frontier in the study of optically excited states in semiconductors. These materials exhibit a plethora of robust excitonic states, such as the optically accessible bright excitons, momentum- and spin-forbidden dark excitons, and hot excitons. In today's talk, I will discuss studies in my lab of photoexcited two-dimensional semiconductors using time-resolved photoemission spectroscopy.


Almost without exception, interpretations of Jacques Ellul's work focus either on his sociopolitical thought or on his Christian reflections. However, each one drives the other, thereby exposing how we collectively journey through time and reality on amagic carpet of myths (in the sense of cultural anthropology). Ellul challenges us to give up these myths and face the relational character of our being in the world, which leads to an iconoclasm and a need for genuine reference points for life. Turning this into a theoretical system of any kind (be it sociopolitical, philosophical, or theological) is a negation of life and an invitation to a new totalitarianism.


The aim in this article is to discuss the use of group work in the Family Health Strategy, focusing on the tensions present in the discursive practices of health professionals about this theme. The information presented here was obtained from audio recordings and transcriptions of "discussion groups", held with professionals working in the Family Health Strategy in a town located in Sao Paulo State, and analyzed based on qualitative procedures of thematic analysis. The nomination of three discursive tensions resulted from this analysis: Therapeutic Group versus Nontherapeutic Group; Adherence as either a patient's responsibility or a team's responsibility; and Directive Coordination versus Participative Coordination. We discuss that these discursive tensions represent challenges to using group work as a resource for healthcare practice, since these tensions still indicate a fragmented perspective of care, a distance in the relationship between professionals and community, and the predominance of a discourse of individual responsibility regarding adherence to treatment.


Proper material constitutive models for concrete-filled tube (CFT) columns of circular cross section and subjected to pure bending moment are proposed. These material models are implemented into the Abaqus finite element program and verified against experimental data. It has been shown that the steel tube does not provide good confining effect to the concrete core when the CFT columns is subjected to pure bending moment. When the diameter-to-thickness ratio of the CFT columns is small, the behavior of the CFT column is the same as the steel tube without a concrete core.


We investigate the subspace of the space of all n × n Boolean (0,1)-matrices, spanned by the powers of an arbitrary matrix. We estimate the maximum dimension of such spaces as a function of n and show that their bases consists of consecutive integer powers of the matrix, starting at I. We also determine the maximum dimension of the space spanned by the powers of as symmetric matrix and characterise the matrices achieving that maximum.


The Atoni people of East Nusa Tenggara, Indonesia, is a community with cultural values in the form of lyrics or dances to celebrate momentums in the lifecycle such as birth, marriage, death, welcoming guests, and the change of seasons, especially the planting season. This research is carried out in Maubesi village, North-Central Timor Regency. This is a qualitative type of research. The data is collected through profound observation and interviews. The researcher becomes the critical informant, and the data is analysed descriptively. From the results of this research, it may be concluded that the rites of the Natoni religion for the Maubesi People, North-Central Timor, East Nusa Tenggara is worship to Uis Neno, which is a belief inherited from the ancestors with special rites. These rites involve the customary structure, including the king, which is completed with rice and betels, and the slaughtering ceremony. This makes the Natoni religion a force or local wisdom which binds the Maubesi people who have embraced other religions such as Catholic and Protestant to carry out the syncretism process, revising the values of that belief. Such rites are then defined as the same as worshipping God the Almighty.

Traumatic spinal cord injury (SCI) results in the partial or complete loss of motor and sensory functions below the neurological level of the injury. In tetraplegic patients, the injury is at the level of the cervical segments of the spinal cord, whereas in paraplegia, the lesions involve the thoracic, lumbar, or sacral regions of the spinal cord. In addition, a spinal cord injury affects somatic and autonomic nervous control of the blood vessels, respiratory tract, sweat glands, bowel, urinary bladder, and sex organs. Dysphagia is a relatively common secondary complication encountered in patients with traumatic cervical SCI. Dysphagia is associated with many negative outcomes, such as pneumonia, malnutrition, dehydration, and a reduced quality of life. In general, the pneumonia risk is greatest in those patients experiencing aspiration. The purpose of this thesis was to determine the incidence and risk factors for laryngeal penetration-aspiration in a cohort of patients with traumatic cervical SCI. In addition, this thesis aimed at describing the recovery of penetration-aspiration and functional oral feeding outcome in these patients. The study sample consisted of a prospective cohort of applicable patients (n=46) with acute traumatic cervical SCI admitted to Tampere University Hospital from February 2013 to April 2015. A videofluoroscopic swallowing study (VFSS) and Rosenbek's penetration-aspiration scale (PAS) were used to determine the incidence of penetration-aspiration. The Functional Oral Intake Scale (FOIS) to determine the functional feeding outcome was used. All the patients received speech therapeutic interventions based on their clinical needs. Fifteen patients (33%) showed aspiration in the first VFSS and the overall incidence of penetration-aspiration was 48%. Of those patients who aspirated, 73% aspirated silently, i.e. without coughing. The clinical signs and risk factors for predicting penetration-aspiration were coughing, throat clearing, choking and changes in voice quality related to swallowing, lower level (C5-Th1) of anterior cervical operation and a necessity for bronchoscopy. The majority (88%) of the patients had a total oral intake without restrictions at the time of the final follow-up. Only one patient (2%) showed persistent aspiration and was still tube-dependent with consistent oral intake. In conclusion, the incidence of penetration-aspiration based on VFSS is high (48%) among patients with acute traumatic cervical SCI with the majority of patients exhibiting silent aspiration. These findings highlight the importance of performing a routine evaluation of swallowing before initiating oral feeding.


As COVID-19 spreading rapidly around the world, there is a huge spike on the needs of pneumonia detection. The traditional convolutional deep neural network has a very strong performance but the training time is a huge problem. As a result, we apply the combination of standard CNN layers and depthwise separable convolutional layers to shorten the training process while not sacrificing too much performance. Also since the training and testing dataset is unbalanced, the evaluation of the model will not simply depend on accuracy, the outcome of the confusion matrix is also quite crucial to the evaluation of the model.


Color and tone adjustments are among the most frequent image enhancement operations. We define a color and tone style as a set of explicit or implicit rules governing color and tone adjustments. Our goal in this paper is to learn implicit color and tone adjustment rules from examples. That is, given a set of examples, each of which is a pair of corresponding images before and after adjustments, we would like to discover the underlying mathematical relationships optimally connecting the color and tone of corresponding pixels in all image pairs. We formally define tone and color adjustment rules as mappings, and propose to approximate complicated spatially varying nonlinear mappings in a piecewise manner. The reason behind this is that a very complicated mapping can still be locally approximated with a low-order polynomial model. Parameters within such low-order models are trained using data extracted from example image pairs. We successfully apply our framework in two scenarios, low-quality photo enhancement by transferring the style of a high-end camera, and photo enhancement using styles learned from photographers and designers.


Given two images f1 , f2 representing the same object, we want to identify geometric correspondences between homologous features in both images. Specifically, we want to find a correspondence function (also called deformation function or deformation field) g(x1)=x2 , where x1 ,x2 are matching coordinates in images f1 , f2 . Here, we intend to concentrate on a non-linear registration (also called elastic matching), characterised by the non-linearity of the function g(x1) .

The purpose of this paper is to study the mathematical basis of some density concepts in Booleanvalued spaces considering possible applications in clustering. Some results concerning closed balls and density in Boolean-valued spaces are proved and some examples of clustering applications are indicated. In particular, a theorem on construction of the least closed ball which includes a given set of elements is established and two equivalent algorithms for his construction are introduced.


The days are a wheel, part light, part shadow. . .This morning I'm reborn from a dream, sensingthe same things from 24 hours earlier:Nothing ever dies. I'm a Flip-in-the-flesh, I am.Then I awaken feeling part Old Navy, part Honda,part steel: a carabao refit with pistons for legs.Today, I scour for real beauty-in-a-box—joy, love, belief, something—I roam among my fellow mechanized, sedated,like yesterday, by the impulsive neon of shopping malls.


BACKGROUND
Resistance to broad-spectrum antibiotics by gram-negative organisms is increasing. Resistance demands more resource utilization and is associated with patient morbidity and death. We describe the implementation of infection reduction protocols, including antibiotic stewardship, and assess their impact on multi-drug-resistant (MDR) healthcare-acquired gram-negative infections.

METHODS
Combined infection reduction and antibiotic stewardship protocols were implemented in the surgical and trauma intensive care units at Vanderbilt University Hospital beginning in 2002. The components of the program were: (1) Protocol-specific empiric and therapeutic antibiotics for healthcare-acquired infections; (2) surgical antibiotic prophylaxis protocols; and (3) quarterly rotation/limitation of dual antibiotic classes. Continuous healthcare-acquired infection surveillance was conducted by independent practitioners using National Heath Safety Network criteria. Linear regression analysis was used to estimate trends in MDR gram-negative healthcare-acquired infections.

RESULTS
A total of 1,794 gram-negative pathogens were isolated from healthcare-acquired infections during the eight-year observation period. The proportion of healthcare-acquired infections caused by MDR gram-negative pathogens decreased from 37.4% (2001) to 8.5% (2008), whereas the proportion of healthcare-acquired infections caused by pan-sensitive pathogens increased from 34.1% to 53.2%. The rate of total healthcare-associated infections per 1,000 patient-days that were caused by MDR gram-negative pathogens declined by -0.78 per year (95% confidence interval [CI] -1.28, -0.27). The observed rate of healthcare-acquired infections per 1,000 patient days attributable to specific MDR gram-negative pathogens decreased over time: Pseudomonas -0.14 per year (95% CI -0.20, -0.08), Acinetobacter-0.49 per year (95% CI -0.77, -0.22), and Enterobacteriaceae -0.14 per year (95% CI -0.26, -0.03).

CONCLUSION
Implementation of an antibiotic stewardship protocol as a component of an infection reduction campaign was associated with a decrease in resistant gram-negative healthcare-acquired infections in intensive care units. These results further support widespread implementation of such initiatives.

This paper deals with the synthesis of a blind channel shortening algorithm for orthogonal frequency-division multiplexing (OFDM) systems operating over doubly selective wireless channels, a challenging scenario that is likely to happen in modern unmanned aircraft systems (UASs) data links. When the length of the OFDM cyclic prefix (CP) is smaller than the channel order, we propose to employ a blind linear time-varying (LTV) time-domain equalizer, which shortens the channel impulse response of the channel in the minimum mean-output energy (MMOE) sense, requiring only estimation of the second-order statistics of the received data. The equalizer design leverages on the complex-exponential (CE) basis expansion model (BEM) for the doubly selective channel, which naturally leads to a frequency-shift (FRESH) filter implementation. Monte Carlo computer simulations are carried out to assess the effectiveness of the proposed FRESH-MMOE channel shortener.


The combined harmonic drive (HD) gearing is a class of differential gears composed of
traditional and HD gears. In this paper, the kinematic analysis and enumeration of these
less known gear devices are discussed. In particular, a new graph-based method of kinematic
analysis has been developed. In order to stimulate the diffusion and applications of
combined HD gearing, an atlas of structurally nonisomorphic gear trains has been
compiled.

Denote by F the field R of real numbers, the field C of complex numbers or the skew-field H of real quaternions. Let F n be the linear space of all column vectors with n coordinates over F A norm on F n is a symmetric gauge function if for any , for all permutations (i 1,…,i n) of (l,…,n), and for all possible choices of . The purpose of this note is to characterize the isometries of symmetric gauge functions on F n . In particular, we show that G is the isometry group of a symmetric gauge function on F n if and only if G is a compact subgroup of GL n (F) containing P n (F), the group of generalized permutation matrices over F. To prove the main theorem, we establish some results concerning the groups that contain P n (F), and characterize all finite subgroups of GL n (R) that contain P n (R), which are of independent interest. While most of these results could be deduced from the advanced theories of Lie groups and reflection groups, elementary proofs are given to them in this paper.


My method of reading Durkheim's (1965 [1915]) The Elementary Forms of the Religious Life recovers as his fundamental interest the following question: How in collective life do we deal with ambiguity as a social phenomenon? The social actor always needs ways and means to bear this burden as something other than oppressive, for example, the conception of a self both finite and infinite, both sacred and profane, both free and constrained. Durkheim challenges the modern conceit that secular society supersedes the attachment to the sacred by exposing the force of the sacred in any society. Durkheim proceeds by formulating the social actor as an automaton and by expanding and enriching the notion of automation to reveal it as having a capacity for a degree of self-affection and affectivity that can be tapped as a resource in creative social action. It is an impersonality towards ambiguity as an impenetrable structure that makes such improvisational action possible as both automated, and yet capable of change through reflective practices that expose such automation.


The aim of this article is to introduce the first contrasting ideas of Merleau-Ponty's Philosophy and the Freudian psychoanalysis, along with the presentation of the "Critics of psychology fundaments" (G. Politzer). Politzer criticizes the Freudian postulation of psychic division, and the postulation of the semantic of conventional language in the determination of the whole living sense. Merleau-Ponty uses these critics for a theory of human expression and existence.


Black women have the highest rates of cardiovascular and cerebrovascular disease prevalence and mortality in part due to blunted vascular function. Psychosocial stress likely also contributes but its relationship to vascular function, remains incompletely understood. Recent studies suggest that internalization and coping strategies are more important than stress exposure alone. We hypothesized that Black women have blunted peripheral and cerebral vascular function and that among Black women, this would be inversely related more with psychosocial stress internalization/coping relative to stress exposures alone. Healthy Black (n = 21; 20 2 yr) and White (n = 16; 25 7 yr) women underwent testing for forearm reactive hyperemia (RH), brachial artery flow-mediated dilation (FMD), and cerebrovascular reactivity (CVR). Psychosocial stress exposure (adverse childhood experiences, ACEs; past week discrimination, PWD) and internalization/coping techniques (John Henryism Active Coping Scale, JHAC12; Giscombe Superwoman Schema Questionnaire, G-SWS-Q) were assessed. RH and CVR (p > 0.05) was similar whereas FMD was lower in Black women (p = 0.007). Neither ACEs nor PWD were associated with FMD in either group (p > 0.05 for all). JHAC12 scores were negatively associated with FMD in Black (p = 0.014) but positively associated with FMD in White (p = 0.042) women. SWS-Motivation to Succeed was negatively associated (p = 0.044) and SWS-Resistance to Being Vulnerable tended to be negatively associated (p = 0.057) with FMD in Black women. These findings indicate that blunted FMD in Black women may be due more to internalization and maladaptive coping than stress exposure alone.

This study aims to develop AN automatic classifier for risk assessment in patients tormented by symptom coronary failure (CHF). The projected classifier separates lower risk patients from higher risk ones, victimisation normal long pulse variability (HRV) measures. Patients area unit labelled as lower or higher risk according to the Heart Association classification (NYHA).A retrospective analysis on 2 public Holter databases was performed, analyzing the info of twelve patients tormented by gentle CHF (NYHA I and II), labelled as lower risk, and thirty two tormented by severe CHF (NYHA III and IV), labelled as higher risk. Solely patients with a fraction of total heartbeats intervals (RR) classified as normal-to-normal (NN) intervals (NN/RR) beyond eightieth were selected as eligible so as to possess a satisfactory signal quality. Classification and regression tree (CART) was utilized to develop the classifiers. A complete of thirty higher risk and eleven lower risk patients were enclosed within the analysis. The projected classification trees achieved sensitivity and a specificity rate of ninety three.3% and 63.6%, severally, in characteristic higher risk patients. Finally, the rules obtained by CART area unit graspable and per the accord showed by previous studies that depressed HRV may be a useful tool for risk assessment in patients tormented by CHF.


Colorectal cancer, the second leading cause of death from cancer in the United States, will claim approximately 56,730 lives in 2004.1 Screening for colorectal cancer lowers both the mortality and the incidence of the disease and is widely recommended for persons 50 years of age or older. Interest in screening has increased in recent years but remains low. Only 53 percent of Americans who are 50 years of age or older have undergone screening within the recommended intervals.2 The needless deaths from and complications of colorectal cancer that occur as a consequence of this low rate of screening make correction . . .


Experimental study in this article is aimed to investigate the effect of reading comprehension improvement for English language students toward their learning difficulty by using the reading speed strategy and identify the effect of gender and teaching method on the improvement of students' reading comprehension. To achieve the objectives, a test was prepared to measure students' reading comprehension after ensuring validity and reliability.

Over the last decade, trade policy reforms have significantly influenced the internationalization of Indian manufacturing firms, leading to deeper participation of the country in global value chains (GVCs) and international production networks (IPNs). With the growing participation of foreign firms in the value chain, the domestic value-added (DVA) content embodied in Indian exports have displayed a declining trend. Recently, in 2020, India has decided to launch the 'Atmanirbhar (self-reliant) Bharat Abhiyan', which, in principle, aims to consolidate the manufacturing sector, leading to increasing DVA embodied in exports (DVA-content), apart from employment generation. The current article attempts to analyse the drivers of India's DVA in exports for select manufacturing industries over 2000–15 by using the OECD trade in value added (TiVA) database. The empirical results reveal that sectoral DVA content is positively influenced by both domestic capital and foreign direct investment (FDI), and labour skill intensity, but negatively influenced by the presence of unskilled workers. Moreover, FDI inflows in sectors characterized by high skill-intensity and high-relative growth rate play a crucial role in influencing DVA content. Finally, the presence of larger and more capital-intensive firms is found to be a major driver of DVA. On the policy front, therefore, the empirical results underline that export promotion policies alone will not be able to resolve employment worries, a major concern in India, as vast numbers of unskilled and low-skilled workers trapped in the agricultural sector or working in unorganized and micro-industries fail to figure in the country's export value addition. A concerted effort towards labour skill enhancement as well as technology transfer is necessary for exports to play a more positive role.


Groenendijk and Stokhof (1984, 1996; Groenendijk 1999) provide a logically attractive theory of the semantics of natural language questions, commonly referred to as the partition theory. Two central notions in this theory are entailment between questions and answerhood. For example, the question Who is going to the party? entails the question Is John going to the party?, and John is going to the party counts as an answer to both. Groenendijk and Stokhof define these two notions in terms of partitions of a set of possible worlds. We provide a syntactic characterization of entailment between questions and answerhood. We show that answers are, in some sense, exactly those formulas that are built up from instances of the question. This result lets us compare the partition theory with other approaches to interrogation—both linguistic analyses, such as Hamblin's and Karttunen's semantics, and computational systems, such as Prolog. Our comparison separates a notion of answerhood into three aspects: equivalence (when two questions or answers are interchangeable), atomic answers (what instances of a question count as answers), and compound answers (how answers compose).

According to them, a question denotes a partition of a logical space of possibilities. In this section, we give a brief summary of this influential theory, using a notation slightly different from Groenendijk's (1999) presentation. A question is essentially a first order formula, possibly with free variables. We will denote a question by ?φ, where φ is a first order formula. (We will also denote a set of questions by ?Φ, where Φ is a set of first order formulas.) An answer is also a first order formula, but one that stands in a certain answerhood relation with respect to the question, spelled out later in this section. For example, the statement Everyone is going to the party (∀xPx) will turn out to answer the question Who is going to the party? (?Px). We assume that equality is in the language, so one can ask questions such as Who is John? (?x≈j). We also assume that, for every function symbol— including constants—it is indicated whether it is interpreted rigidly or not. Intuitively, for a function symbol to be rigid means that its denotation is known. For example, under the notion of answerhood that we will introduce below, it is only appropriate to answer Who is going to the party? (?Px) with John is going to the party (Pj) if it is known who John is—in other words, if j is rigid. Also, for Who is John? (?x ≈ j) to be a non-trivial question, John must have a non-rigid interpretation. Questions are interpreted relative to first order modal structures with constant domain. That is, a model is of the form (W,D, I), where W is a set of worlds, D is a domain of entities, and I is an interpretation function assigning extensions to the predicates and function symbols, relative to each world. Furthermore, we only consider models that give rigid function symbols the same extension in every world. Relative to such a model M = (W,D, I), a question ?φ expresses a partition of W , in other words an equivalence relation over W : (1.1) [?φ]M = { (w, v) ∈W 2 | ∀g : M,w, g |= φ⇔M,v, g |= φ } . Roughly speaking, two worlds are equivalent if one cannot tell them apart by means of the question ?φ, in other words if φ is never true in one world and false in the other. In general, any set of questions ?Φ also expresses a partition of W , namely the intersection of the partitions expressed by its elements: [?Φ]M = ⋂ φ∈Φ[?φ]M = { (w, v) ∈W 2 | ∀φ ∈ Φ: ∀g : M,w, g |= φ⇔M,v, g |= φ } . (1.2) Entailment between questions is defined as a refinement relation among partitions (i.e., equivalence relations): An equivalence relation A is a subset


19 We develop a tractable non-parametric model for the time-varying repro-20 ductive rate of infectious diseases that combines the structure of a 21 deterministic compartmental model and a stochastic model for inci-22 dence data. We use Bayesian inference to estimate, with uncertainty, the 23 reproductive rate of the Coronavirus 2019 outbreak in the U.S. states 24 of California, Florida, Michigan, New Mexico, New York, and Texas 25 from January 2020 to March 2022. We use the inferred reproduc-26 tive rates to estimate the posterior distribution of the time-varying 27 reproduction numbers for each state. Compering the time-varying repro-28 duction numbers across the states, we identify some epidemic waves, 29 potentially driven from changes in human behavior and virus mutations.


In this paper, the whole system starts with a real time picture of the sender and the receiver. The pairing is done utilizing the image of the sender and the receiver at the place of the pin used for pairing. The key generation for the encryption also utilizes the facial characteristics of the parties involved. This method will always generate a key of variable length. As the same person taking the snap of his/her face will change the coordinates every time making it is hard to predict the exact key. The text converted into ciphertext is also padded from both sides with variable bits to make it hard to identify the starting point of the ciphertext to start the actual decryption. The overall aim of this research is to develop a cryptosystem that can be used for achieving good encryption even if the length of the plain text is very small(one or two words). It is an encryption system with associated authentication. An electronic device cannot distinguish between its real users and fake one just by looking at the number which is used for the authentication process but if trained to identify the picture of the used the device up to a certain point is secure. Next thing if someone has requested a pairing merely by looking at the numbers one cannot predict that a legal connection is made but by looking at the real-time image of the person the same can be done with satisfaction. Previously used encryption used key and ciphertext of fixed length but here, a variable ciphertext and key are created in every session of transmission as the image of every sender and the receiver is different.

Power systems of today are large and complex, and their control is very difficult. flexible AC transmission systems (FACTS) controllers have been readily accepted as feasible means for power flow control for enhancing the steady and dynamic performances of power system during normal and abnormal conditions. Among different FACTS devices, the unified power flow controller (UPFC) is regarded as the most generalized version since it serves to control the three parameters at the same time. This paper presents the different modeling approaches and studies the effect of UPFC parameters for their control objectives. The proposed algorithm has been illustrated on an IEEE 30-bus system.


Considering that each sentence element of a sentence or clause plays an important role in describing case and (or) object in documents, a feature extraction method based on sentence element is proposed in this paper. The method can extract feature terms from documents effectively and weight them accurately. It first extracts sentence elements from dependency relationships, and then selects and weights the terms according to the sentence elements. Experimental results on a public dataset prove the feasibility of our approach and demonstrate its advantage to feature extraction method based on part of speech.


An important consideration for APC feedback control of photolithography overlay is the uncertainty in estimating the correctable overlay parameters. This uncertainty is affected by the metrology sampling plan, particularly the spatial layout of the sampling points along with the number of sampling points. This current study looks at the combined effect of the spatial coverage and sample size factors, under two levels of random noise and a systematic non-correctable factor.


Since 2011,the global arms race of cyber is intensifying.In order to realize the cyber deterrence and seek the strategic advantage,USA has issued some programmatic documents to promote the development of cyber security,including National Strategy for Trusted Identities in Cyberspace,International Strategy for Cyberspace,and Action Strategy for Cyberspace.From the Clinton administration to the Bush Administration,and to the Obama administration,USA is gradually developing cyber security-related aspects of organization control,network technology and military capabilities,aiming at taking further control over the power of setting the security standards and rules of international Internet in a new round of "network warfare".This article analyzes the evolution process and characteristics of American cyberspace security strategy and provides some enlightenment for our country.


This article presents selected issues related to the workpiece surface quality after machining by the laser sintering of AlSi10MG alloy powder. The surfaces of the workpiece were prepared and machined by longitudinal turning with tools made of sintered carbides. The occurrence of breaches on the machined material surface was found, which negatively influence the values of 3D surface roughness parameters. The occurring phenomena were analyzed and proposals for their explanation were made. Guidelines for the machining of workpieces achieved by the laser sintering of powders were developed. The lowest value of the 3D roughness parameters was obtained for f = 0.06 mm/rev, ap = 0.5–1.0 mm, and for the nose radius of cutting insert rε = 0.8 mm. The results of research on the effect of cutting parameters on the values of parameters describing the surface quality are presented. Topography measurements and 3D surface roughness parameters are presented, as well as the results of a microscopic 3D surface analysis. Taguchi's method was used in the research methodology.


SUMMARY This paper explores the organisational changes that have taken place in teacher education in Norway in recent years. It focuses particularly on the two largest of the 26 state colleges and explores two key themes: the ways in which leaders of teacher education in those institutions, and those from the former system, perceive the changes in the organisation of teacher education; and how they are meeting the new challenges being faced. This case study has important implications for similar reforms currently taking place in other European countries.


Changes in shape of 1D profiles of small-single-crystal Bragg reflections have been examined in terms of the shapes of the components which, convoluted together, generate the profile. In most practical cases, operational features require truncation of the angular scan range of measurement and the conventional linear formula for scan range, ω = a + b tan θ, is then not strictly valid. A more appropriate relationship involves a combination of root mean square (RMS) and linear (LIN) forms, ω = [(p′)2 + (q′ tan θ)2]1/2 + (p′′ + q′′ tan θ) where p′ is associated with the leading and trailing edges of the distribution of the combined θ-invariant components and p′′ with its plateau width while q′ is associated with the leading and trailing edges of the distribution of the wavelength component and q′′ with the separation of its outer peaks if there are more than one. For operational purposes, this relationship can be substituted with adequate precision by ω = [c2 + (d tan θ)2]1/2, but the parameters c and d do not then have a simple relationship to the θ-invariant and θ-variant components. Use of a conventional linear formula when a RMS one is the relevant one can mean that, in the lower θ range, the estimate of integrated intensity will be too high and, in the higher θ range, it will be too low, so that, with increasing θ, a positive then a negative systematic error is introduced and not merely a negative error as the conventional interpretation of truncation holds. The conclusions of the present analysis are tested against experimental data where the conventional treatment for truncation failed [Eisenstein & Hirshfeld (1983). Acta Cryst. B39, 61-75]. For the estimation of integrated intensity, and hence of structure factors, which are consistent over the operational range of θ, a RMS formula for the scan range is advisable.


This paper presents a three DoF MAGLEV vibration compensating measurement platform (MP) with arbitrary operation orientation for robot-based surface inspection of free-forms. The MP design comprises an internal position sensor system which is used in feedback control to maintain a free-floating position in six DoFs with respect to its supporting frame when approaching a sample (stabilization mode). In addition, the integrated design includes three tracking sensors measuring the out-of-plane position of the MP to a sample surface. The entire system can be mounted as an end effector of an industrial robot with the MP carrying a desired measurement tool. Disturbing environmental vibrations are actively compensated by maintaining a constant position of the MP with respect to a sample surface (tracking mode). The control design includes SISO position controllers for all DoFs, achieving a bandwidth of about 130 Hz. By means of a cross-fading error gain, an efficient control transition between stabilization and tracking mode is enabled. A vibrating target is used to evaluate the vibration compensation performance of the tracking module for standardized floor vibration profiles. Attenuation between -35 and -20 dB for out-of-plane vibrations below 40 Hz is achieved. In the time domain, vibration profiles with 15.7 μm rms and 95 μrad rms are reduced to 1.6 μm rms and 21 μrad rms, respectively.


This paper proposes the theoretical foundations of a new formal tool for symbolic verification of finite systems. Some approaches reduce the problem of system verification to the reachability problem in term rewriting systems (TRSs). In our approach, states are encoded by terms in a BDD-like manner and the transition relation is represented by a new rewriting relation so called functional term rewriting systems (FTRSs). First, we show that FTRSs are as expressive as TRSs. Second, we present the implementation of our FTRS-based tool as well as optimisations based on local fixpoint computations. Our experiments show that for well-known protocols (e.g., tree arbiter, percolate, leader election protocol,...) our tool is more efficient than other rewriting tools such as Timbuk, Maude or Tom. Moreover, it can also be applied to check invariant properties which are a particular subclass of linear temporal logic (LTL) formula.


The effectiveness in the public sector is a movement that was influenced by the introduction of the new public management (NPM). This means a 'privatisation' of the public sector from a belief that public sector was a waste of money. Power (1997, p. 10) argues that the introduction of NPM helped the monitoring practices meeting public ideals. This NPM helped to make things 'auditable' creating the opportunity for Value for Money (VFM) audits, for example, that supported the practice of government by shaping their programmes in more efficient, economical and effective (Power, 1997, pp. 10-11). The major problem is NPM assumes a neoliberal perspective originated from the private sector, but it limited to the broader needs of societies. Audit, in this, is a practice of a neoliberal assumption (power, 1997, p. 43).


This paper presents archaeobotanical research and analysis from Prehistoric Mainland
Southeast Asia in order to understand the development of cereal agriculture in the region.
It draws where possible on other disciplines to confirm and strengthen hypotheses. There
is enough complementary evidence from archaeobotanical, genetic, morphometric and
carbon isotope studies to explore issues on agriculture in Southeast Asia. As a result, we
can have a better understanding of the key components that characterise early agricultural
development in SEA, particularly the subspecies of rice introduced and cultivation
systems practiced. This discussion will be enriched in the future with more studies on
plant remains and through a continuation in the discourse between other disciplines and
studies from neighbouring regions.


In this paper, we present some sufficient conditions for the stability of nonlinear systems with impulse time window by using some inequality techniques and results of matrix analysis. The proposed results are simpler than ones shown by Feng et al. [Y.-M. Feng, C.-D. Li, T.-W. Huang, Neurocomputing, 193 (2016), 7–13]. Finally, several numerical examples are given to show the effectiveness of our results. c ©2017 All rights reserved.


Dr. Zaborowski has served the National Federation of the Blind (NFB) in a number of capacities previous to her appointment on December 1, 2003, as executive director of the National Federation of the Blind Jernigan Institute. Her highest priority has been to assist with the development of the Jernigan Institute, soon to be the country's foremost center for innovations in education, employment, and adaptive technology services, operated by an organization of blind people. After a successful $19.5 million capital campaign, the new 170,000-square-foot building housing this new institute held its Grand Opening on January 30, 2004. Dr. Zaborowski, in close consultation with the leadership of the NFB, will supervise the staffing, equipping, and rollout of programs in the new Institute. The Institute, under Dr. Zaborowski's supervision, has already launched three Inaugural projects: NFB Science Camp—two sessions in partnership with NASA scheduled to roll out summer 2004, Online courses—four scheduled to be in full operation by July 1, 2004, and the development of the first hand-held reading machine for the blind—the Kurzweil National Federation of the Blind Reader— scheduled for first-stage consumer testing fall 2004.


Background: Most cases of gastric cancer (GC), which is one of the most common cancers in China, are diagnosed at an advanced stage. The first-line treatments for GC include 5-fluoropyrimidine (5-FU)-based chemotherapy. However, the cancer cells may develop 5-FU resistance. The inhibition of angiogenesis can be an alternative therapeutic strategy for GC. Recent studies have demonstrated that TIE2-expressing monocytes/macrophages (TEMs), a subtype of tumor-associated macrophages (TAMs), exhibit profound pro-angiogenic activity. The herbs used in traditional Chinese medicine can be a potential source of anti-cancer agents and can improve the therapeutic efficacy of chemotherapy drugs. In this study, the role of TEMs in the synergistic anti-cancer effects of Fu-Zheng-Jie-Du ointment (FZJD) and 5-FU was evaluated.Methods: The migration of TEMs was evaluated using the transwell assay. Tube formation assay and quantitative real-time polymerase chain reaction analysis were used to determine the pro-angiogenic activity of TEMs. Tumor-bearing mouse model and immunohistofluorescence stain were used to evaluate the anti-tumor effect of FZJD and the underlying mechanism.Results: FZJD inhibited the migration and pro-angiogenic activity of TEMs. Additionally, tumor growth in the mice co-treated with FZJD and 5-FU was lower than that in the mice treated with FZJD or 5-FU. Immunohistofluorescence stain revealed that the migration of TEMs was not inhibited upon treatment with FZJD alone or in combination with 5-FU. Moreover, treatment with FZJD did not decrease the endothelial cell population. In contrast, the treatment combination of FZJD and 5-FU markedly decreased the endothelial cell population.Conclusions: FZJD improves the anti-cancer efficacy of 5-FU through the inhibition of TEM-mediated angiogenesis.


In the LI-ID system, the supermnducting roils are fed by supermnducting power-leads, ie. the supermnducting bus-lines. Considering electric insulation aspects, the supermnducting bus-lines don't have voltage detection leads just close to the oonductor. The voltage detection leads are running along the thermal insulation pipe apart from the ronductor. Therefore, we have to take into a<munt some difficulties to detect the normal voltage of the bus-lines due to the heavy electromagnetic noises into the detection signal. In order to solve this problem, the authors proposed a detection system to cancel the voltages of the positive and the negative bus-line oonductors each other. And, in this system, Fuzzy theorem is applied inoorporating not only the voltage signals but also other signals, e.g. the liquid He inlet flow rate, the currents, etc .. The signals are digitally processed by PCS, and through some Fuzzy calculation we obtain the "dangerous rate" of the bus-lines. As shown in Figure 1, the voltage taps are attached on the power lead ternrinals both at the power supply side and the SC ooil side. As for the voltage signal cable, the positive and the negative voltage signal wires are wound together tightly on the thermal insulation pipe of the bus-lines .. The quench detection system basing on this principle was applied to the superoonducting bus-lines, and the data were oollected at some excitation experiments of the LI-ID. Two PCs and AID ronverters were used. Signal wires were ronnected to AID ronverter board. A quench detection experiment was carried out at the LI-ID site. The monitored signals are, 1) the
