Active EMI noise cancellation can be an effective way to reduce the cost, volume and weight for filtering with motion control systems at both supply and load side. The amount of EMI noise power generated is typically less than 10% of the nominal motion power converted. Direct (analog) feedback systems are limited by latency and therefore limited in cancellation bandwidth. Motion control systems have three main frequency components for disturbances: the power mains frequency, the pulse width modulated frequency (PWM) i.e. sampling frequency and the motion frequency, all with their (inter-)related harmonics. Digital signal processing compensation techniques offer alternatives but have restrictions too. In this paper, these noise compensation bounds will be explored, and some solutions will be given.


To overcome the difficulties in simulating accurately the blasting vibration of surrounding rock,an equivalent simulation method was presented.The equivalent elastic boundary subjected to the blasting load was developed for multiple boreholes according to the spatial character of rock damage around boreholes.Blasting loads on the equivalent boundary varying along the borehole axis was calculated theoretically through analyzing the expansion of borehole volume,the development of cracks,the movement of stemming and the outburst of detonation gases.Combined with the blasting excavation of the No.1 tailrace tunnel in Pubugou Hydropower Station,particle vibration velocities in the surrounding rock were simulated by employing this equivalent method based on the dynamic finite element method.The comparison between the simulation results and the monitoring data indicates that this equivalent simulation method is applicable to calculating the response of surrounding rock during blasting excavation;and that the selection of mechanical parameters of the rock near the equivalent elastic boundary has a significant impact on calculation results.

The flood incident of Garang watershed on 6 and 24 February 2021 inundated some of Semarang City. Total area of inundated area is about 47% of Semarang City or 176 km2. A research was conducted to estimate the contribution of sub-watersheds in flood peak and flood volume, and to analyze the causes of the flooding and its solutions. The flood peak discharge was estimated using Rational method and flood volume using Curve Number (CN) method. Geographic Information Syatem (GIS) is used for calculating Runoff coefficient and Curve Number. Overlay of landcover map, slope map, and soil map produce runoff coefficient map while the CN value was obtained from over lapping land cover maps, soil hydrology group, application of soil and water conservation techniques, hydrological conditions, and antecedent soil moisture content in each sub watershed. Garang watershed consists of 4 sub watersheds namely Garang upland, Kreyo, Kripik, and Garang lowland with area of 85.33; 65.36; 38.83; and 23.20 km2. The results showed that specific flood peak on 6 February 2021 were 3.9; 3.2; 3.6; and 3.4 m3/second/km2 for the Garang upland, Kreyo, Kripik, and Garang low land subwatershed. Specific flood volume on Feb 6, 2021 were 91,471; 91,396; 96,605; and 99,058 m3/km2. Garang up land sub watershed has highest specific peak flow and Lower Garang sub watershed has highest specific flood volume. The cause of flooding in the Garang watershed was caused by high rainfall intensity and watershed degradation. Flood peak and flood volume can be reduced by applying some water conservation techniques and increasing vegetation cover.


People die conveniently in George Eliot's novels. Grandcourt falls off a boat and drowns at the moment when Gwendolyn finds her murderous fantasies unbearable. In "Mr. Gilfil's Love Story" Anthony collapses immediately before Caterina comes to the Rookery with the intention of killing him. Casaubon dies immediately before Dorothea comes to the garden to promise against her will to obey her husband's wishes after his death. By dying at the right moment, Robert Dempster saves Janet, and Tito saves Romola from their decisions to rededicate their lives to their marital duties. By falling in a brook, Thias Bede saves his sons from the burden of a drunken father; and Maggie Tulliver saves herself from a life of pain and privation and finds reconciliation with her brother in their deaths in the flood. Few of these deaths are improbable or merely accidental. George Eliot carefully leads us to expect that Casaubon, Robert Dempster, Anthony, and Thias Bede will ultimately die of the illnesses that in some way symbolize their personal failings. Through much of Romola Baldassare prepares his vengeance against Tito, and The Mill on the Floss frequently looks forward to a return of the flood that has given St. Ogg's its name. Nevertheless, there is something peculiarly providential about Eliot's location of these deaths within the plots of the novels. It is not so much the deaths themselves that strike us as strange as the fact that they occur at such propitious moments. The novelist who so repeatedly insists that providence will not save us from the consequences of our own actions nonetheless saves a number of her characters from those consequences. Is there a pattern to the situations in which these deaths occur? What function do they serve in the plots of the novels? And finally, what does the pattern of providential death indicate about Eliot's own psychology? What situations does it allow her to avoid portraying and what situations does it permit her to bring her characters to confront? The very convenience of all the deaths that I have mentioned reveals the pattern that they have in common: each effectually ends a deep and seemingly permanent alienation between the character who dies and the character most intimately related to him, usually his wife, who stands to be most affected by his death. Thus each death at one and the same time satisfies the survivor's aggressive feelings while it removes him or her from the situation that had inspired hostility. Whether the character, like Caterina or Gwendolyn, had abandoned herself to her aggressive feelings and planned to murder the man she hated, or


: Wound healing is a repair process at cellular and tissue level. It begins immediately after an injury to the epidermal layer. The repair process includes organized cellular proliferation, and remodeling mechanisms. There are large numbers of cell types including lymphocytes, fibroblasts, and endothelial cells. Traditional herbal medicines are used for wound healing. A plant Tridax procumbens (L.) is very commonly used as herbal medicine in healing wounds. The medicinal use of Tridax has inspired the author for histochemical studies which would be providing important information. This histochemical study reveals and compares content of glycogen and lipids in the blood vessels in control and Tridax leaf extract treated samples. The effect of Tridax leaf extract was studied on carbohydrate (glycogen) and lipid by histochemistry on 48 h and 96 h chick embryo vitelline blood vessels. These biomolecules are large and complex molecules that play many critical roles in the body. For histochemical work it is important to have ways of demonstrating these bio molecules. The histochemistry of Glycogen in developing blood vessels was studied using alum hematoxylin. Sudan black staining is used to detect the lipid content. The application of histochemical study and tests for quantitative estimation is discussed in connection with the characterization of these biomolecules. The objective of this histochemical study was to evaluate the effect of Tridax procumbens leaf extract for the characterization of these biomolecules with respect to healing properties in the early chick embryo.


The wastewater treatment is an effective method for alleviating the shortage of water resources. In this article, a data‐driven iterative adaptive tracking control approach is developed to improve the control performance of the dissolved oxygen concentration and the nitrate nitrogen concentration in the nonlinear wastewater treatment plant. First, the model network is established to obtain the steady control and evaluate the new system state. Then, a nonquadratic performance functional is provided to handle asymmetric control constraints. Moreover, the new costate function and the tracking control policy are derived by using the dual heuristic dynamic programming algorithm. In the present control scheme, two neural networks are constructed to approximate the costate function and the tracking control law. Finally, the feasibility of the proposed algorithm is confirmed by applying the designed strategy to the wastewater treatment plant.


The present paper is concerned with numerical studies of composite T-joints which are made of carbon fibre composite (CFC) materials. CFC materials are used due to their high load carrying capacity and lightweight. The composite T-section is formed at the spar-lower skin joint section in aircraft wings. The behaviour of such joints is very complex. In this study, a brief account of the problem is first presented and areas of principal interest which most influence joint behaviour are identified. A thick composite shell finite element is specially developed and it is then used for a detailed finite element analysis of composite T-joints. Though several types of forces act on the spar, in the present case, a pull-out force is applied on the top of the web to determine strength and to study the behaviour of T-joints. Parametric variations account for two different stacking sequences and variations in filler area and radius of curvature at the web/skin interface. Accuracy of the present finite element analysis is established by comparing present results with the published ones. Numerical results obtained through parametric variations are presented and discussed to understand the joint behaviour.


The comparative economics of utility ash disposal by five conceptual design variations of ponding and landfill were evaluated for a 500-MW power plant producing 5 million tons of ash over the life-of-project. For a basic pond disposal without water reuse, the total capital investment from hopper collection through one-mile sluicing and pond disposal is $52/kW (1982$). Comparable total system investment using trucking to a landfill is $30/kW. All disposal site construction costs were fully capitalized in both cases and this convention affects the comparison of annual revenue requirements. First-year annual revenue requirements for the ponding system are 1.85 mills/kWh (1984$), while those for the landfill system are lower at 1.66 mills/kWh. On the other hand, levelized annual revenue requirements are 2.26 mills/kWh and 2.42 mills/kWh respectively. Disposal site costs are the major element in all types of disposal and constituted the major difference in cost between pond and landfill disposal. Reuse of sluicing water and additional provisions for the disposal of self-hardening (high calcium oxide) ash added relatively little to costs.


While the issue of environmental protection and sustainable development has been richly explored in theory, the practical implementation of the rules and principal into social life and enterprise practice has remained neglected. The paper focuses on environmental education, whose aim is the changeover in thinking and attitudes of the present-day economically active population and that of the young generation. Environmental education is to be understood from the conceptual aspect as an organic part of the entire complex of education and training, not excluding further professional education. Environmental education is not the most recent issue: formal education has been dealing with the nature protection and care for the environment since the 1970-ies. Environmental education is promoted in all types of schools, either in direct in-class instruction or indirectly through special interest (hobby) education. It is essential to pass from the theoretical analysis and discussions about environmental problems to their utilisation in practice. An important role in this process is played by managers. The focus of our empirical research is on attitudes, opinions and environmental thinking of line managers. The paper is a partial outcome from the nation-wide research project scheme VEGA, No. 1/0328/21: "Post-pandemic Business Management: identification of temporary and sustainable changes in sequential and parallel management functions in the context of the COVID-19 pandemic".


In the United States, Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen. There are estimated to be 3 million new infections each year. Chlamydial genital tract infections are a major cause of urethritis, cervicitis, and pelvic inflammatory disease (PID) in women and are an important cause of ectopic pregnancy, infertility, and chronic pelvic pain. Chlamydial infections are responsible for 25% to 50% of the 2.5 million cases of PID that are reported annually in the United States. Infections are also related to adverse pregnancy outcomes such as miscarriage, premature rupture of membranes, preterm labor, low birth weight infants, infant mortality, and postpartum infections. Perinatal transmission to infants can cause neonatal conjunctivitis and pneumonia. Chlamydial infection in men is the cause of 30% to 40% of the 4 to 6 million visits each year for nongonococcal urethritis and 50% of more than 150,000 cases of acute epididymitis. Rarely, men may experience chronic complications of chronic prostatitis, reactive anthritis, urethral strictures and possibly infertility. Chlamydia is a cofactor in transmission of human immunodeficiency virus infection. In the United States in 1994, the estimated cost of untreated chlamydial infections and their complications was $2 billion.


Generally, providing individual feedback, in the case of large-sized classes, is near impossible
or would require disproportionate effort to do so. Generic feedback, instead, has a little
value in enhancing students' learning and their satisfaction. Consequently, the authors of
this paper have proposed a novel methodology to overcome the two extremes of such
feedback procedures i.e., individual feedback and generic feedback. In this paper, the
authors propose a pseudo-personalized feedback mechanism in which the feedback is
clustered into several categories according to the correlation in the student response to the
assessment. The feedback process is completed in partnership with the students.


The environment of production is very complicate in metallurgical firms, and exist many corrosive factors. The problems of construction control that brought about by corrosion of reinforcement are frequent, such as loss of service life, high maintenance cost and so on. This text inquires into influencing factors and treatment measures from mechanism analysis of reinforcement corrosion.


The article presents the results of an epidemiological study of the prevalence and intensity of inflammatory periodontal diseases (IPD) in the northern and southern parts of Ufa, as well as the need for complex periodontal treatment. The number of visits by primary persons for periodontal care in the NW is 2.1 times less than in the SW. The rank values of common risk factors for the development of IPD have been identified. When assessing the KPI index, the risk to this pathology and its difference in different parts of Ufa, taking into account the nosological form and gender, were identified. With acute gingivitis, men living in NW and SW were statistically equally treated to a periodontist, while women living in NW were 1.8 times more. With acute periodontitis in the NW, men visit a periodontist 1.9 times more than in the SW, and women, on the contrary, in the SW are 1.2 times more likely to visit than in the NW. With chronic forms of IPD, the differences in treatment among men and women were not statistically significant and did not depend on the area of residence.

Cell cycle regulators such as cyclins, cyclin‐dependent kinases (cdks) and their inhibitors control the growth of cells. SDI1/CIP1/WAF1/p21 is a potent inhibitor of G1 cdks, whose expression is induced by wild‐type p53. To elucidate the mechanism of growth inhibition by transforming growth factor β1 (TGFβ1), we examined the effect of TGPβ1 on the expression of p21, G1 cyclins and cdks by human gastric cancer cell lines. TGFβ1 induced p21 expression and subsequently suppressed cdk2 kinase activity, followed by a reduction in phosphorylation of the product of the retinoblastoma tumor suppressor gene in TMK‐1 cells, which are responsive to TGFβ1. Coimmunoprecipitation analysis demonstrated that TGFβ1 increased the level of p21 protein present in complexes with cdk2. In contrast, TGFβ1 did not induce p21 in TGFβ1‐resistant MKN‐28 cells. TGFβ1 did not affect the levels of p53 mRNA and protein in TMK‐1 and MKN‐28 cells, which contain mutated p53 genes. These mutated p53 complementary DNAs, when overexpressed, failed to activate transcription from the p21 promoter. Furthermore, TGFβ1 caused a reduction in the steady‐state level of cyclin A protein concomitantly with inhibition of cdk2 kinase activity in TMK‐1 cells. These results suggest that the growth inhibition of tumor cells by TGFβ1 is associated with p53‐independent induction of p21, subsequent suppression of cdk activity and a decrease in cyclin A protein in TMK‐1 cells.


Cultural Competence, weight management, obesity Over the past 10 years there has been a threefold increase in the rates of child and adolescent overweight (OW) and obesity (OB) in the United States (Hedley, Ogden, Johnson, Carroll, Curtin, & Flegal, 2004; Ogden, Carroll, Curtin, Lamb, & Flegal, 2010). During the 2007-2008 National Health and Nutrition Examination Survey (NHANES), the prevalence of OB among children aged 2-19 years was reported to be 16.9% (Ogden & Carroll, 2010). Ogden, et al. (2010) found that 31.7% of 2-19 year old children and adolescents were at or above the 85th percentile for body mass index (BMI) for age during the 2007-2008 NHANES survey. These concerning statistics have captured the public attention and have led to the development of programs to prevent childhood OB. For example, First Lady Michelle Obama initiated the Let's Move initiative in response to the concerning rise in the rates of childhood OW and OB (White House Task Force on Childhood Obesity, 2010). Family-based weight management programs, especially parent-focused programs, are one effective approach to combat the growing rates of childhood OW and OB (Birch & VenAbstract Increased rates of childhood overweight and obesity are a major public health concern in the United States. Family weight management programs are one effective approach to preventing and treating childhood overweight and obesity. With changing demographics and socioeconomic disparities in the rates of childhood overweight and obesity, it is more important than ever for clinicians and researchers to understand parents' health-related values, beliefs, and practices in order to implement culturally competent weight management programs. The process of achieving cultural competency when conducting family weight management strategies will be discussed. Specific experiences using the Ways to Enhance Children's Activity and Nutrition (We Can!) program with a group of diverse parents in Georgia will be highlighted, along with specific lessons learned about cultural competency when delivering the We Can! Program. www.ojccnh.org


Modern library has the educational functions.The electronic reading room,as an important department of the college library,with its peculiar features,plays an outstanding role in the higher education.To be specific,its four functions are to widen students' knowledge,cultivate their learning abilities,master the modern information technologies and to create favorable learning conditions.


With the method of sample plot investigation,plant species diversity of southern slope on Zixi Mountains was studied.Four indicators including Margalef index,Shannon index,Simpson diversity index and Pielou index were chosen for analyzing the diversity of plant,woody plant and shrub plant one by one.The results showed that(1)as altitude increasing,Margalef index,Shannon and Simpson diversity index of plant species diversity all increased first and then decreased,presenting a single-peak distribution pattern,while Pielou index increased all the time with altitude increasing,appearing a positive correlation pattern;(2)the four indexes of woody plant species diversity were all increasing at first and then decreasing,showing a single-peak distribution pattern,the four indexes of tree species diversity all appeared a single-peak distribution pattern as well;(3)the four indexes of shrub and herb species diversity all increased first and then decreased,and then increased and decreased again,appearing a pattern of bimodal distribution.


Purpose In light of the systemic and pervasive nature of ableism and how ableist ideology structures—or limits—educational opportunities, there is an ongoing conversation within the field of multicultural education regarding how to meaningfully include dis/ability in K-12 curricula. Design/methodology/approach This paper explores how elementary and middle school health textbooks from two prominent publishers in the United States portray dis/ability through quantitative and qualitative content analysis methods of 1,468 images across texts. Findings Findings indicate that the majority of the textbook portrayals of dis/ability tacitly forward assimilationist ideals. Specifically, the textbooks assume and speak to a normatively-abled reader, pointing out those with dis/abilities as different from the reader. Additionally, mainstream or normative markers are provided as evidence of success and those with dis/abilities who have been successful as such are positioned as overcoming their limitations. This paper extends the tradition of curricular analysis as one of the first studies to examine the portrayals of dis/ability in U.S. health textbooks and offers practical implications for educators.


Fracturing operation curves can reflect a lot of reservoir information, including permeability, filtration property, earth stress, fracture rupture and extension. Taking two typical wells of Xuejiahe Formation in central Sichuan Basin, well Tongnan 3 and well Ying 23, as examples, this paper applies drawdown curve, G function, net pressure, fracture shape and supporting profile to analyze the fracturing operation curve characteristics and to evaluate the postfrac effect. At last, an acknowledgement to Xujiahe low-permeability sandstone gas reservoir is further strengthened.


Due to new energy electric vehicle market developing rapidly, a series of energy supply problems in the charging system urgently need to be solved. The two subsystems of this new energy photovoltaic charging station system are studied respectively. Firstly, the topology equivalent circuit diagram of a three-level pulse width modulation rectifier is proposed. And a simplified space vector pulse width modulation algorithm is applied to the control of the current inner loop and voltage outer loop of three-level AC/DC. A three-level bidirectional DC/DC converter was introduced, its power characteristics and implementation conditions of soft switching were analyzed, and a phase shift modulation method was proposed to achieve its intelligent control. The results indicate that in the dynamic performance analysis of the simplified space vector pulse width modulation algorithm, the phase of phase A current and voltage are in a synchronous state before and after adding a load. After adding the load, the A-phase voltage remained stable at 300V, but its maximum current increased from 80A to 150A. At the same time, the maximum value of three-phase current suddenly changed from 80A to 150A after the load was added, and subsequently stabilized at about 150A. In the power characteristic experiment of a three-level bidirectional DC/DC converter, when the set current Iset is positive, the current value of the input current IinF of the primary bridge arm stabilizes at 11.5A around 0.025 seconds. When the set current Iset is negative, the current value of the input current IinF of the primary bridge arm stabilizes at −11.5A around 0.020s. This shows that the three-level bidirectional DC/DC converter can convert the photovoltaic system's output voltage to the voltage requirements on DC side of the inverter. The three-level AC/DC and three-level bidirectional DC/DC converters used in this study have significant performance advantages, providing reliable technical support for the photovoltaic charging station technology of modern new energy electric vehicles.


The management of severe myasthenia gravis presents a continuing challenge to the physician. Even with the most careful adjustment of anticholinesterase medication the patient may become severely disabled. Thymectomy seems to offer real benefit to some of the carefully selected patients. However, despite the careful employment of anticholinesterase medication and the improvement after some thymectomies, some patients still cannot be adequately controlled and become severely disabled and die. In 1951 Torda and Wolff treated these refractory myasthenia patients with ACTH. They obtained a 'significant partial remission' after corticotropin therapy in 10 of 15 patients. They recognized, however, that a transient and sometimes severe exacerbation of weakness was apt to occur during the first days of treatment. One of their 15 patients died during such an exacerbation. Their report was directly contradicted by Grob and Harvey, who reported in 1952 that in none of their 10 patients was any increase in strength observed either during or after ACTH administration. In subsequent years, however, there have been additional reports (Grob and Namba, 1966; Osserman and Genkins, 1966; von Reis, Liljestrand, and Matell, 1966) of remissions lasting three months or longer. Such remissions were more consistent after massive doses of ACTH. von Reis et al. (1966), for example, gave 1,000 u. ACTH over a period of six to 12 days to 13 patients and obtained excellent results in 23 out of 33 courses of treatment. Ample clinical experience has shown that massive doses of ACTH will often bring about a remission when myasthenia is otherwise refractory to medication. The reports have uniformly noted that initiation of treatment carries danger because of transient increase of weakness, and all have lamented the brevity of the remission which might


Considering the large number of test samples,high cost of experiment,long time of evaluation and high evaluation index in the current reliability assessment for large-scale electronic system,a small sample of large system Bayes evaluation method is proposed in this paper,which is based on multi-source information fusion. Since the proposed algorithm considers the effects caused by various factors to the reliability assessment for large-scale system comprehensively,it will get accurate evaluate results even when the number of test samples is small. Finally,the feasibility and effectiveness of the proposed algorithm is validate by an example of mission reliability assessment for integrated electronics system.


Abstract Different types of international financial integration have different effects on cross-country business cycle co-movement. International business cycle transmission through financial integration occurs through the wealth and balance sheet effects. The balance sheet effect leads to business cycle convergence, but the wealth effect leads to divergence. Using a crosssectional regression, this paper shows that cross-border credit market integration (debt) has a positive effect on co-movement, implying that the balance sheet effect is the main conduit for international transmission through credit markets. However, cross-border capital market integration (equity) has a negative effect, implying that the wealth effect is the main channel for international transmission through capital markets. By distinguishing between wealth and balance sheet effects, this paper resolves many discrepancies between some key empirical and theoretical findings in the open economy macro literature, between different studies in the theoretical literature, and between empirical studies that use a cross-sectional regression and those employing panel data.


Is ERA testing different between RIF patients with control group?

 In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. What is known already: The endometrium receptivity analysis testing might have the ability to detect the implantation window. In repeat implantation failure patients, detecting of precisely implantation window may have some benefits.

 This was a single-center retrospective observational study. Two hundred and forty-nine patients who underwent ERA testing following frozen-thawed embryo transfer in our center were including in this study between January 2019 and May 2020.

 181 patients having unexplained repeated IVF failure (RIF group, at least tow implantation failure) and 68 patients having no experience with embryo transfer (Control group) who underwent ERA testing were including in this study. Both of Patients having a receptive (R) ERA and having a non-receptive (NR) ERA underwent a personalized embryo transfer (pET) on ERA. ERA results and clinical outcomes compared between RIF group and control group were analyzed by Chi-square test.

 The proportion of R/NR results were 33:35 for the RIF group and 118:63 for the Control group, demonstrating the displacement of the window of implantation in patients with RIF. Our results revealed an endometrial factor in 51% RIF patients, which was significantly greater than the Control group 34.8% (P = 0.02). Among the patients with NR ERA result, there are not significantly difference in clinical pregnancy rate in the RIF group compared with control group (57.1%. vs. 61.9%). The clinical pregnancy rate of the patients with receptive ERA result also is comparable in both group (70.3% vs. 66.7%).

 This is a retrospective, single center study with limited case number. There were may some bias with ERA testing errors.
 Wider implications of the findings: In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. Larger randomized studies are required to validate these results.

A study of the photometric accuracy of deconvolved astronomical images was undertaken by processing two simulated images with several well-known algorithms. The simulations consisted of an image of a simple star field and an image of an active galactic nucleus (AGN). Each image was mathematically convolved with a known PSF and then deconvolved to recover the original image. Measurements and comparisons were made before and after the deconvolution to check for photometric accuracy. The best result for the star field was obtained with the multiscale Richardson-Lucy algorithm. When measuring the differential photometry of the nucleus of the AGN between different frames, leaving the image in its convolved state gave a closer variability result to the original than any deconvolution method.


Summary 1. A strain of Sarcoma 180 maintained by routine trocar implant passage in CFW mice has been isolated and serially propagated in vitro from biopsy specimens in a medium containing only the growth factors demonstrably essential for the HeLa cell and the L strain of mouse fibroblasts. The generation time in these media is circa 30 hrs and this cell line is now in the 32 nd transplant, having undergone more than 100 generations during 230 days in vitro. 2. Inocula prepared from these cultures after 215 days in vitro have produced characteristic sarcomata within 3-5 days in 100% of the CFW mice implanted subcutaneously with 1.0 × 105 or more cells. The ED50 in CFW mice is circa 4.5-5.0 × 103 cells, and the latent period between injection and the development of palpable tumors increases with decreasing inocula.

By providing a control method when the voice card is inserted during transmission of the audio book, the remaining data of the audio book may be issued after a voice card reading mode is executed, without the occurrence of errors due to mishandling of the user.


those of other investments. Accordingly, this paper uses the capital asset pricing model (CAPM) to estimate risk premiums required to hold farm real estate in a well-diversified market portfolio. Risk premiums are estimated for farm real estate at the national level and for ten farm production regions of the United States. CAPM results then are evaluated in light of farm real estate's unique characteristics.


Biocatalysis is a growing field in the production of fine chemicals and will most probably increase its share in the future. Enzymatic reactions are carried out under mild conditions, i.e., non-toxic solvents, low temperature and pressure, which eliminates most environmental drawbacks associated with conventional production methods. The superiority of chemo-, regio- and enantioselectivity of enzymes exhibit significant advantages over conventional catalysts for production of fine chemicals, flavors, fragrances, agrochemicals and pharmaceuticals. Enzymes can function both in aqueous and non-aqueous solvents. As a result of the growing scientific and industrial interest towards green chemistry, green solvent systems, which are mainly water, supercritical fluids, ionic liquids, fluorinated solvents, and solvent-free systems have become more popular in biocatalysis. However, the activity and selectivity of an enzyme is heavily dependent on solvent properties. In this review, various green solvents were classified and some of their influential features on enzyme activity were discussed.


Sports turfs in the North China were warmed by the means of artificial heating for the root zone during the winter season (December to February). The results show that the turfground temperature in all the treatments were significantly higher than control and atmosphere(P0.01). That was 6~9℃ in average higher than atmosphere during December to February. The turfground temperature was higher by the method of heating water(sun energy) with plastic cover than single plastic cover and electric cables with plastic cover. The plastic cover which was removed for 12 h/week(8-20 o'clock) appeared better effects for warming turfground than no removing and 12 h/d removing treatments. The single plastic cover treatment was the best method for warming turfground in winter for its efficiency,simple operation and economy with the using cost of 4.90 yun/m~2. As for turfground temperature, the heating water(by sun energy) with plastic cover was best treatment, but the using cost was also the highest (14.69yun/m~2). The using cost of electric cables with plastic cover treatment was 8.97yun/m~2.


The pollen grains have a definite shape, size, colour, structure for each species, genus and family and these characters are useful for systematical botany. The pollen has nutritive properties due to its content: proteins, lipids, carbohydrates, vitamins, hormones and minerals. In the Romanian flora vegetate three species of Sambucus, but only S. nigra L. (elder or black elder) supplies a vegetal medical product, Sambuci flos or elder flowers, whereas the others species S. ebulus L. (dwarf elder) and S. racemosa L. (mountain elder or red elder) are considered adulterations. The pollen of Sambucus species were already studied using optical microscopy (Tarnavschi et al.), but the images are in one single layout, therefore the structure details cannot be easily notice. In this context the pollen grains of the three species already mentioned above were studied by SEM (Scanning Electron Microscopy). The results demonstrated that this pollen have a small-middle size, oblat-sphaeroidal-prolat shape, threecolpat and the exine adornments are of reticulate type, haemitectate with sticks in the meshs of polygonale net. The flavonoids content is lower than in others species (0.146-0.564 %). The SEM analyse of Sambucus pollen allow a reliable identification of the genus but less for the species.


The germinal center is a unique site of the lymphoid tissues where positive selection of B cells takes place in response to T-cell-dependent antigens, resulting in apoptosis of a large number of B cells. Although various molecules have been reported to be involved in this selection, only a few comprehensive studies have been performed in terms of apoptosis-related molecules implicated in apoptosis of germinal center B cells. In this review, we mention the expression of apoptosis-related molecules in the germinal centers, based on our own data especially focusing on Bcl-2 family proteins. In contrast to an antiapoptotic protein, Bcl-2, which was strongly expressed in mantle cells, but absent in most germinal center B cells, the other antiapoptotic proteins, Bcl-XL and Mcl-1, and the death-inducer proteins, Bax and Bak, were expressed in germinal center B cells. This expression pattern was comparable to that of Fas and CPP-32 (caspase-3). These results suggest that apoptosis of germinal center B cells is regulated by the concerted action of Bcl-2 family proteins and other apoptosis-related molecules including Fas and that the balance between antiapoptotic and death-inducer proteins caused by homodimerization and heterodimerization is important.


This paper deals with a simulated annealing neural network model for determining sequences of models inputted into a mixed model assembly line. We first present a energy function fitting to our problem, next determine the value of the parameters of the energy function using convergence ratio and the number of searched feasible solution. Finally we compare our model NMS with the modified Thomopoulos model. The result of the comparison shows that NMS and Thomopoulos offer a similar output in the problems having good smoothness.


11 Benthic foraminifera are abundant marine protists which play an important role in the transfer 12 of energy in the form of organic matter and nutrients to higher trophic levels. Due to their 13 aquatic lifestyle, factors such as water temperature, salinity and pH are key drivers controlling 14 biomass turnover through foraminifera. In this study the influence of salinity on the feeding 15 activity of foraminifera was tested. Two species, Ammonia tepida and Haynesina germanica, 16 were collected from a mudflat in northern Germany (Friedrichskoog) and cultured in the 17 laboratory at 20 °C and a light / dark cycle of 16: 8 h. A lyophilized algal powder from 18 Dunaliella tertiolecta, which was isotopically enriched with C and N, was used as a food 19 source. The feeding experiments were carried out at salinity levels of 11, 24 and 37 practical 20 salinity units (PSU) and were terminated after 1, 5 and 14 days. The quantification of isotope 21 incorporation was carried out by isotope ratio mass spectrometry. Ammonia tepida exhibited a 22 10-fold higher food uptake compared to H. germanica. Furthermore, in A. tepida the food 23 uptake increased with increasing salinity but not in H. germanica. Over time (from 1-5 d to 14 24 d) food C retention increased relative to food N in A. tepida while the opposite was observed 25 for H. germanica. This shows, that if the salinity in the German Wadden Sea increases, A. 26 tepida is predicted to exhibit a higher C and N uptake and turnover than H. germanica, with 27 accompanying changes in C and N cycling through the foraminiferal community. The results 28 of this study show how complex and differently food C and N processing of foraminiferal 29 species respond to time and to environmental conditions such as salinity. 30 31 keywords: benthic foraminifera, feeding experiments, salinity, isotope tracing 32 33


Nearly two decades ago, predictions were made that the computer would replace the wind tunnel. While the prediction has not come true, the dependence on Computational Fluid Dynamics (CFD) in the aircraft design process has increased dramatically. IofNEWT combines the two methodologies, wind tunnels and computations, together with experimental instrumentation, supercomputers, scientific visualization, networking, remote communications and expert systems to create a real-time aerodynamic development environment. The resulting synergy produces a capability for providing increased data and its subsequent conversion to understanding and knowledge of aerodynamic phenomena, as well as changing the paradigm for wind-tunnel testing. A sub-element of IofNEWT is the Remote Access Wind Tunnel (RAWT) which allows real-time access and interaction with the wind tunnel and supercomputing facilities from the remote user sites. The presentation addresses the evolution of the IofNEWT program, including RAWT, and implementations accomplished thus far. During two 1994 wind-tunnel tests, experimental results were combined in real-time with numerical simulation data of the wind-tunnel configurations, including complex facility effects. The results were presented simultaneously to on-site and off-site users, with off-site interaction capabilities.


AbstractInteractions of glucopyranose, fructopyranose and sucrose with a proteinaceous receptor model have been examined to validate the stereomolecular mechanisms of sweet taste proposed for sugars. The methylene groups at C-6 of glucose, at C-1 and C-6 of fructose and at C-6, C-1' and C-6' of sucrose appear to play an important role as dispersive interaction centres with the receptor.


In the last years, with the success of Internet and the rapid development of storage and processing technologies computing resources have become cheaper, more available and powerful. This technological development has triggered the emergence of Cloud Computing, a new paradigm for services over the internet. In Cloud Computing resources can be rented to users following an on-demand payment model through Internet, this payment model is very attractive to enterprises because they do not have to care about maintenance or provisioning, availability or connectivity, neither binding contracts, they can begin with a small amount of resources and resize them immediately in order to supply an increase in the incoming traffic, following the business evolution. Because of these advantages nowadays a lot of companies are adopting the Cloud Computing paradigm, mainly enterprises that realised that exchanging the initial costs for a pay-per-use model was worth it, in addition to others that offer on-premise services installations and desire to increase their reach and expand horizons. This is just the case that we are dealing with here, 2Mares Demil, S.L. 2Mares has been 22 years working on technological specialized innovations, manufacturing intelligent software products for Contact Centers. They are leaders in Spain in their sector, serving the largest companies and now they want reach small entities, but there are a few problems about this, the on-premise installation cost is too much for this companies, and for 2Mares the maintenance cost in terms of support staff in comparison with the incoming benefit is not admissible. These are the main reasons because 2Mares decided jump to the Cloud Computing environment, initial installation costs would be removed and the need for support staff greatly reduced, in this way reaching small entities would be possible.


In this paper, we propose a novel multi-color balance method for reducing color distortions caused by lighting effects. The proposed method allows us to adjust three target-colors chosen by a user in an input image so that each target color is the same as the corresponding destination (benchmark) one. In contrast, white balancing is a typical technique for reducing the color distortions, however, they cannot remove lighting effects on colors other than white. In an experiment, the proposed method is demonstrated to be able to remove lighting effects on selected three colors, and is compared with existing white balance adjustments.


Dissolution rate of a drug substance can be strongly influenced by the experimental conditions employed, among which agitation intensity and pH value were recognized as the most important. A complete two-factor, three-level factorial design followed by multiple regression analysis was applied in order to investigate the influence of pH and agitation intensity on paracetamol (CAS 103-90-2) and acetylsalicylic acid (CAS 50-78-2) dissolution from conventional tablets. Mean dissolution time, amount of drug dissolved after 30 min and first-order dissolution rate constant were evaluated as response variables in terms of their applicability to characterize different release profiles. The obtained results indicated that factorially designed experiments present a valuable tool in dissolution method development. Mean dissolution time showed to be the most useful response criterion capable to differentiate between dissolution curves of different shape.


The article deals with the history of the Museum of Contemporary Art in the Soviet and Russian culture in the 20th and early 21st centuries. The milestones in the museum history, such as, creation, methods of acquisition and presentation of the collections, public relations, etc. are reviewed throughout two periods in Russian history i.e. the 1920s and the 1990s-2000s. The experience of recently created museums is analysed: Museums of Artistic Culture and the State Museum of New Western Art, as well as the departments of contemporary art of the Russian Museum and the Tretyakov Gallery and the Moscow Museum of Contemporary Art. All these were opened in the 1990s.


The content inconsistency of the normative provisions of criminal and operative-search legislation is examined in the article. The technical and legal deficiencies that reduce the results of anti-corruption are defined. The measures to eliminate existing problems are proposed.


The demand of energy, global warming and greenhouse gas emission have forced the world to look into alternative sources of energy. Solar thermal technologies are regarded as the most promising technology that can supplement the usage of fossil fuels in power generation. Among the solar thermal technologies, parabolic trough solar collectors (PTC's) from the concentrated solar power (CSP) technology are the most matured application for the production of electricity and steam generation. The development of parabolic trough solar collectors has been carried out throughout the world for different thermal applications ranging from industrial heat process to generation of electricity. In Malaysia, the use of solar thermal technology for the generation of electricity and industrial heat process is not given much attention. Therefore, the objective of this paper is to review the development of parabolic trough solar collectors (PTC's) for different thermal applications and pointing out some challenges and prospects associated with the development of PTC in Malaysian environment.


The invention provides a method for detecting shake allowance of a sofa. The method is carried out according to the following steps: (1) flatly placing an instrument on a proper position of the back of the sofa in an original free state, and resetting read number of an angle; (2) after an endurance test, flatly placing the instrument on the proper position of the back of the sofa under a sustained load condition, and reading the number of the angle which is back shake allowance X; and (3) under an unload condition, re-detecting the number of the angle which is back residual shake allowance Y. A survey meter used by the detecting method consists of a base, a transverse square tube, a transverse round tube, a vertical steel block, a vertical round tube, a moving scale, an angle sensor and a display. The method and the survey meter have the advantages that: 1, the detecting method can detect the back shake allowance and the back residual shake allowance of the sofa conveniently and quickly, thereby not only improving the working efficiency, but also improving the detecting precision, and reducing the error rate in surveying and measuring processes; and 2, the survey meter used by the method has simple structure, convenient and quick operation and high stability, and can survey the sofa at various angles.


This paper deals with the state estimation of the nonlinear stochastic models with continuous dynamics and discrete measurement. Namely, the numerical solution to the Fokker-Planck equation, representing the estimator time update, is explored. Unlike the classical approaches, which use the finite difference method and operate on a standard rectangular grid, this paper utilizes finite volume method on the logically rectangular grid. In particular, the circular grid is chosen, which better approximates an estimated conditional probability density function support and improves time update accuracy without any impact on the its computational complexity. The benefits of the solution are illustrated in a numerical example. Keywords: State estimation, Bayesian inference, Nonlinear systems.


The Los Angeles to Pasadena Metro Gold Line Rail Transit Project provided many challenges with a variety of different geotechnical conditions along its alignment. The conditions include areas of deep existing fill soils at Union Station and the Yard and Shops area. Evaluations were made as to whether the existing fill could be used for support or whether the fill should be improved. The project includes a major crossing over the Los Angeles River where there were different soil and rock conditions at the two major pier locations. The project crosses a known active landslide area which required evaluation of stability and adequacy of mitigation measures. The project includes two areas of below grade construction in materials difficult to excavate; one of the areas was adjacent to an historic commercial district with many older unreinforced masonry buildings sensitive to ground movement. The project also had a crossing over the trace of an active earthquake fault.


The transformation processes of Pb and Cd in granitic latosol of Hainan Island were characterized and the effect of exotic heavy metals (Pb and Cd) and three soil amendments on their chemical forms in the soil studied. Results show that the major fractions of Pb in the original tested soils are in bond and residual forms. Lower content of the available form of Pb indicates low environmental risk. The percentage of the different forms of Pb is in the order of: residual organic Fe-Mn oxide carbonate ex-changeable water soluble form. The major fractions of Cd in the original tested soils are in the form of Fe-Mn oxide bond and carbonate bond. The higher content of exchangeable Cd indicates high environmental risk. The percentage of the different forms of Cd is in the order of: Fe-Mn oxide carbonate exchangeable organic residual water soluble form. With increasing loads of exotic heavy metals (Pb and Cd) in the soils,the tendencies are that Fe-Mn oxide Pb residual Pb organic Pb carbonate Pb exchangeable Pb water soluble Pb,and that exchangeable Cd Fe-Mn oxide Cd carbonate Cd residual Cd organic Cd water soluble Cd. The application of three soil amendments (calcium superphosphate,lime and sodium sulphide) significantly reduces the percentage of Pb and Cd in water soluble and exchangeable forms; and organic Pb,carbonate Pb and Fe-Mn oxide Pb decline. However,residuals of Pb,carbonate-Cd,Fe-Mn oxide bound Cd and organic Cd increase. Cd residual is basically stable.


The influence of local ground conditions on the parameters of seismic vibrations is the subject of study in seismic microzonation. This section of engineering seismology underwent radical changes at the end of the last century. The Commission on Seismic Safety of the National Institute of Building Sciences of the United States, as part of the implementation of the National Earthquake Damage Reduction Program, developed new NEHRP Recommendations, which are significantly different from all that has been used in the world practice of anti-seismic construction. The main provisions of this NEHRP classification have been adopted in many national building codes, including Eurocode 8 and Kazakhstan's seismic regulations. One of the essential features of the classification is the use of the average values of the velocities of transverse waves and the densities of the ground thickness with a thickness of 30 meters. In Russia, the provisions of the NEHRP norms have not yet been properly developed. Currently, the issue of extending the norms of Kazakhstan to the entire territory of the CIS countries is being considered. For this reason, the article examines in detail both the advantages and disadvantages of the NEHRP Recommendations in order to extract useful experience and adapt to the realities of Russian anti-seismic construction. In particular, the error in the representation of the parameters of the soil mass by average values is shown. The ways of overcoming the identified shortcomings of the description of the soil mass with the help of model representations are outlined


Previously, the authors conducted phytochemical investigations of the aerial parts of Larrea tridentata and reported triterpene glycosides and lignan derivatives. In continuation of the preceding studies, 17 lignans and lignan glycosides (1–17) were isolated, including seven new compounds (1–7). Herein, the structure of the new compounds was determined based on spectroscopic analysis and enzymatic hydrolysis. The cytotoxicity of 1–17 against HL-60 human promyelocytic leukemia cells was examined. Compounds 4–11 and 14–16 were cytotoxic to HL-60 cells, with IC50 values in the range of 2.7–17 μM. Compound 6, which was the most cytotoxic among the unprecedented compounds, was shown to induce apoptotic cell death in HL-60 cells.


A new smartphone irrigation scheduling application (VegApp) was compared with current irrigation scheduling recommendations and an automated soil moisture sensor (SMS)–based irrigation system in southern Georgia during Spring 2016 and 2017. Plants were grown using plastic mulch and drip irrigation following standard production practices for watermelon (Citrullus lanatus) in Georgia. The VegApp irrigation regime was based on evapotranspiration (ETo) values calculated from real-time data collected from a nearby weather station. Current irrigation scheduling recommendations use a water balance (WB) method. The WB method uses historic averages for determining ETo rates for the season. Water applied, soil water tension at 6-, 10-, and 14-inch depths, yield, and fruit quality were evaluated. In 2016, the SMS-based irrigation plots applied the least water. In 2017, the lowest amount of water was applied to plants grown using the VegApp. Total marketable yields were not significantly affected by irrigation regime. However, 45-count fruit yields were affected by irrigation in 2017. Plants grown using SMS-based irrigation had significantly higher yields of 45-count fruit than those grown using the WB method. Irrigation water use efficiency (IWUE) was affected by irrigation treatment and year. The SMS-irrigated plants had the greatest IWUE, although it was not significantly different from plants grown using the VegApp irrigation program. Internal quality parameters including, firmness, hollow heart, and total soluble solids (TSS) were not significantly affected by irrigation scheduling during the study. The results suggest that overall water applications may be reduced and yields maintained when using VegApp compared with traditional WB methods of irrigation scheduling.


It is well recognised that performance practices and their development are intricately linked to media and technology. The intermedial in live performance is both a technological and a performative phenomenon. It points at once to the incorporation of digital processing for inter-media communications within performance; and correlatively, to performance that occurs within this in-betweeness of mediality. The incorporation of digital technology does not just expand and alter the sensory and temporal aspects of live performance, but it affects process as well as content and form. Systems of varying complexity are developed to enable inter-communication between different media and elements in real-time. Through feedback loops between different elements, dynamic and non-linear events could be generated real-time. Performance becomes the choreography of a relational system - playing through the field of combinatorics, patterning and the transformational. Translation between media means the boundaries and distinctions between media becomes blurred or even fused. The implication of this isn't only ontological, it affects meaning and signification as well as performativity. Intermedial performance is a form of multi-medial staging where media are not just layered and juxtaposed with one another; instead modalities and media are being transformed and mediated through the other, producing a fabric of inter-relations where often the other is the transcoding of the one thing in another form. Representation or remediation through transcoding involves a reductive process; this materialist idea of translating quantitative and qualitative values and relations from one medium to another transposes our conventional idea of meaning creation. Intermedial performance presents an expansion of how we construct and think about meaning and performance through the process of mediation and remediation. This paper's exploration includes a case study of "Quartet" presented by Margie Medlin.


A new method for feedstock reconstruction of hydrocarbon fractions is developed by using as input the analytically determined commercial indices.Thirty two real components are selected to describe the pyrolysis reaction performance of naphtha.And a set of equations including 32 equations is established according to the commercial indices,such as specific density,hydrogen content,PONA weight fraction and ASTM boiling points curve.We can solve the set of equations,and find a good correspondence between the simulated result and the analytically one.The model can be used in a simulation package for steam cracking.


This paper presents a semi-empirical model for determining the energy consumption of an injection molding machine based on the energy profile of the injection molding process. The model utilizes empirical data to the idle or baseline energy consumption of the machine tool, which is non-negligible. A theoretical analysis is used to determine the processing energy, which can be a significant contribution because of the design and the rheological non-Newtonian nature of polymers. A thermo-mechanical analysis of the material plasticizing and injection process is incorporated into the model to accurate assess the theoretical processing energy. The errors in the model are considered and the model performance is validated with findings in literature.


Manililla is a mango variety whose residues contain bioactive compounds such as polyphenols and flavonoids, with high added value. The use of environmentally friendly extraction technology would be of great relevance; hence, this study aimed to evaluate the effect of solvent relation, sonication time and amplitude on the ultrasound-assisted extraction of total polyphenols in Manililla mango residues (peel, endocarp and kernel) and antioxidant activity. An experimental design 23 with a central point was used to evaluate the curvature behavior of the process variables. Conventional maceration was used as a control. The better conditions were obtained at the central point using 50% ethanol in water, 60% amplitude and 20 min of sonication time. We obtained values of up to 1814 mg GAE/100 g, 469 mg GAE/100 g and 672 mg GAE/100 g of total polyphenols and 1228 mg QE/100 g, 653 mg QE/100 g and 880 mg QE/100 g of total flavonoids for peel, endocarp and kernel, respectively. Mangiferin was quantified in ultrasound-assisted extraction at 150 mg/g in peel and 0.025 mg/g in the kernel, but it was not detectable in maceration. An antioxidant capacity of 87%, 14% and 83% inhibition for peel, endocarp and kernel, respectively, were obtained. Peel and kernel were the residues with higher potential as extraction material, while endocarp was not.


Abstract The criteria of homogeneity and structure were proposed by Goodman (1981a) for determining whether certain rows or columns of a contingency table should be grouped. A data-based procedure (using the canonical form of bivariate distributions) is presented in this article to guide exploratory analysis to determine which rows or columns of a table may be grouped. This procedure facilitates the application of the homogeneity criterion. Relationships between the proposed method of grouping and the structural criterion are discussed as well as simultaneous inference for grouped tables. The grouping method is extended to multiway tables. The use of canonical forms as a model exploratory tool is addressed. Examples are discussed in detail.


n engl j med 376;15 nejm.org April 13, 2017 1487 lieve that asking about the sex of a person's partner is a less accurate and more judgmental assessment of risk than a questionnaire that asks about, for example, frequency of partner exchange, condom use, and prior screening for human immunodeficiency virus (HIV). In their guidance for industry, the FDA reports that, as of 2013, men who have sex with men accounted for 2.6% of male blood donors, despite the existing ban.1 Thus, a blanket deferral policy, while widely seen as discriminatory, is also ineffective at excluding this population. Too often this issue is framed as a false choice between maintaining a safe blood supply and ending a policy that perpetuates stigma. With modern HIV testing and individual risk-based assessments, both can be achieved. We acknowledge the complexity of the issue, including the possible financial implications for the global market,2 and support the effort to reassess this policy, as guided by the best scientific evidence.


Network survivability is defined as the ability of a network keeping connected under failures and/or attacks. In this paper, we propose two stochastic models, binomial model and negative binomial model, to quantify the network survivability and compare them with the existing Poisson model. We give the mathematical formulae of approximate network survivability and use them to carry out the sensitivity analysis on model parameters. Through a numerical example it is shown that the network survivability can change drastically when the number of nodes is relatively small under a severe attack mode which is called the Black hole attack.

The author was invited by the Library's Officers on the eve of his retirement as National Librarian in 1979 to undertake a complete study of the Library's history to the present time. Ill-health permitted him to complete only part of the task, namely this history of the Library from its foundation to 1951. Sadly Dr David Jenkins died a few months before the work was finally published. The study is a fitting memorial to his dedication to the National Library of Wales over many decades, and a very fitting tribute to a national institution that will celebrate the centenary of its Royal Charter in 2007. It can only be hoped that the National Library's Officers can engage the services of a historian before that date to complete the task of compiling the definitive history up to the present time. The title of the work reflects the National Library's significance during the Second World War when it 'provided a refuge from enemy bombing for many of Britain's artistic and literary treasures, which were evacuated from the principal London museums and galleries'. This was a feature of its contribution and a period in its history regarded as particularly ironic and significant by the author, himself a decorated soldier, but it tends to understate the immensely important place and wider role of the National Library in the life of Wales. Its history is also a microcosm of the history of Wales and its relationship with British government in London, during the same period. The author had at his disposal the administrative archive of the National Library of Wales, some earlier attempts to write brief histories of the foundation of the Library, the vast store of published and archival materials held by the Library, to which he added much anecdotal material. The author had, after all, been part of the history and story of the National Library of Wales for more than a decade of the forty or so chronicled here and knew many of the dramatis personce referred to, either personally or by recent reputation. He was able to distil the most interesting and salient material, retain the necessary objectivity, present plausible, sound explanations and interpretations of events, and has succeeded in producing an immensely readable and worthy history of the National Library of Wales from its foundation to 1951. There are many splendid nuggets in that history as presented by Dr Jenkins. The concept of establishing a National Library has its roots in a Welsh national cultural reawakening at the end of the nineteenth century. He has successfully and succinctly placed the Library in its context. The development of the concept, the marshalling of support and the creation of the necessary circumstances and resources also relate to the national awakening in education, and to the establishment of the national university. That history is also traced in a clear manner. The realization of the dream reflects the immense contribution of certain key individuals and not a little political cunning and opportunism. Dr Jenkins is at his best when addressing those aspects. One cannot fail to be amazed by the philanthropy of the founding father, Sir John Williams, a Welshman who had built his reputation and fortune as Royal physician. To all intents and purposes, he devoted his later life and almost entire wealth to the well being of the National Library of Wales. One cannot but admire the manner in which certain Welsh Members of Parliament gave active support to the establishment and development of the Library through their work in the corridors and smoke-filled rooms of Westminster, and at lueetings throughout Wales.


An earlier article described a laser flying spot scanner for investigating the surface finish on the bores of components such as the hydraulics cylinders used in motor vehicle braking systems. The quality of finish on their internal surfaces must be very high; even small scratches or blow holes may lead to failure of the braking system, with dangerous consequences. The previous paper outlined a method for processing the signal from the photodetector, so that such defects may be identified. However, difficulties were experienced with this method of signal processing, which proved to be unduly sensitive to low frequency variations in the observed intensity of light reflected from the bore. Improved signal processing was therefore required. In this article, we describe the results of an experimental investigation using an interactive image analyser. It has been possible to demonstrate, by incremental simulation, that scratches can reliably be detected using an algorithm based upon a procedure which seeks and removes intensity anomalies.


Tuning application performance on modern computing infrastructures involves choices in a vast design space as modern computing architectures can have several complex structures impacting performance. Moreover, different applications use these structures in different ways, leading to a challenging performance function. Consequently, it is hard for compilers or experts to find optimal compilation parameters for an application that maximizes such performance function. One approach to tackle this problem is to evaluate many possible optimization plans and select the best among them. However, executing an application to measure its performance for every plan can be very expensive. To tackle this problem, previous work has investigated the use of Machine Learning techniques to predict the performance of the applications without executing them quickly. In this work, we evaluate the use of graph neural networks (GNN) to make fast predictions without executing the application to guide the selection of good optimization sequences. We propose a GNN architecture to make such predictions. We train and test it using 30 thousand different compilation plans applied to 300 different applications, using ARM64 and LLVM IR code representations as input. Our results indicate that the control and data flow graph can then learn features from the control and data flow graph to outperform nongraph‐aware Machine Learning models. Our GNN architecture achieved 91% accuracy in our dataset compared to 79% when using a nongraph‐aware architecture–taking only 16ms to predict a given input. If the application been optimized took an average of 10 s to execute, and we evaluated 1000 optimization sequences, it would take almost 9 h to assess all pairs, but only 16 s with our GNN .

The forging process has traditionally been done by skilled experts using their past experience, intuition and the trial and error method. Even in this computer era, only a very few computer aided tools are available for this oldest manufacturing process. The present work explains the development of a feature based design system that has been applied in the concept-to-manufacturing stages of the forging process. It is broadly divided into four modules namely, feature-based design (FBD), virtual factory environment (VFE), feature mapping for forging (FMF) and process planning (PP). The FBD module is used for the design, modelling, synthesis, representation and validation of the component for the forging application. It uses integrated features, which are pre-defined as feature templates in the developed feature library. While instancing these integrated features, the database gets/derives the information required for the design, modelling, process planning and manufacturing stages of the component as its attributes, from the user/knowledge base. After creating the component, the integrated features present in the model are validated with respect to the forging process. The VFE module defines the layout model of the factory on the computer, and provides the database for the machines, machine tools, tools, work pieces, etc. The FMF module contains the knowledge base for preparing the forge model, die impressions, parting line/surface, etc. The PP stage is used to find the process parameters like forming sequence, shape of pre-form and finisher die sets, temperature of billet and dies, forming speed, die stroke, material for die sets and workpieces, etc. This feature based design system has been built using existing CAD, programming and spread sheet software tools namely CATIA®, MS-Visual Basic® and MS-Excel®, which not only save developmental effort, but also make full use of the functionalities of these commercial software tools. This paper explains the developed system with a case study.


Fused Deposition Modeling (FDM), Inkjet – powder bed and Stereolitography (SLA) are the most investigated technologies which offer a promising tool for pharmaceutical technological application. The industrial significance of 3D printing was supported by the FDA approval of the first 3D printed medicine Spritam® (Aprecia Pharmaceuticals) combining the precision of 3D printing and formulation science to produce rapidly disintegrating levetiracetamcontaining tablet for oral suspension. Besides the industrial utilization 3D printing can transform healthcare through personalized medicine, thus improving patient compliance by tailoring the medication to the patient. This can be achieved through on-demand manufacturing in clinical settings to offer the best medical care. FabRx Ltd. (UK) applies FDM technology to produce personalized tablets (printlets) based on the physiological parameters of each individual patient. Their development in field of rare diseases, metabolic disorders and nutraceuticals already reached clinical trial phase. Besides pharmaceutical formulations, Additive Manufacturing (AM) also has a huge impact in the medical device industry. The best fit for the given patient in orthopedic implants can be achieved by Digital Imaging and Communications in Medicine (DICOM) processing connected with metal 3D printing.

ABSTRACT Analysing roll call votes from the energy and climate policy field in the Eighth European Parliament (2014–2019), this article asks why has the European Parliament succeeded in maintaining its relatively ambitious position and how national and partizan factors explain voting behaviour of Members of the European Parliament (MEPs) on EU energy and climate legislation. We find the Eurosceptic vs. pro-EU cleavage to be the main conflict line structuring voting on energy and climate policy. Additionally, EU energy and climate policy has been supported by MEPs from member states with a track record of more ambitious climate policymaking and those with higher energy dependence. We show that increasing party fragmentation in the European Parliament has strengthened the influence of some progressive party groups, particularly the Greens, and has enhanced the European Parliament's ability to mobilize support for a relatively ambitious energy and climate legislation.


OBJECTIVE—Engraftment and function of human islet cell implants is considered to be dependent on their rapid and adequate revascularization. Studies with rodent islet grafts have shown that vascular endothelial growth factor (VEGF) expression by β-cells can promote this process. The present work examines whether human islet preparations produce VEGF as well as interleukin (IL)-8, another angiogenic protein, and assesses the role of contaminating duct cells in VEGF and IL-8–mediated angiogenesis. RESEARCH DESIGN AND METHODS—Human islet and pancreatic duct cell preparations are compared for their respective expression and production of VEGF and IL-8 during culture as well as following transplantation in nonobese diabetic (NOD)/scid mice. The associated angiogenic effects are measured in an in vitro aortic ring assay and in an in vivo chick embryo chorioallantoic membrane assay. RESULTS—Cultured pancreatic duct cells expressed 3- and 10-fold more VEGF and IL-8, respectively, than cultured human islet endocrine cells and released both proteins at angiogenic levels. The angiogenic effect of purified duct cells was higher than that of purified endocrine islet cells and was completely blocked by a combination of IL-8 and VEGF antibodies. Human duct cell implants under the kidney capsule of NOD/scid mice expressed higher levels of IL-8 and VEGF than human islet cell implants and induced circulating IL-8 and VEGF levels during the first day posttransplantation. CONCLUSIONS—Human duct cell–released IL-8 and VEGF may help revascularization of currently used human islet cell grafts. Further work should examine whether and when this effect can prevail over other inflammatory and immune influences of this cell type.

It has been reported that anti-dementia drugs are useful for improving cognitive functions and activities of daily livinge, and for delaying being under the care of nursing homes. Behavioral and psychological symptoms of dementia (BPSD) are other difficult problems of dementia, as well as cognitive impairments. Patients with severe BPSD cannot even be cared for by institutions, such as nursing homes or group homes, and finally become inpatients of psychiatric hospitals for dementia patients. Recently, some anti-dementia drugs have been reported to show adverse effects, such as worsening BPSD. It is wondered whether or not BPSD of some patients with dementia might be worsened by antidementia drugs, resulting in being admitted as inpatients of psychiatric hospitals for dementia patients. In the present study, we report how anti-dementia drugs have been prescribed before and after admission as inpatients to Sendai Tomizawa Hospital, a psychiatric hospital for dementia patients. A total of 81 dementia patients were admitted to the second floor of Sendai Tomizawa Hospital from April 2012 to March 2013, and BPSD related to antidementia drugs were compared before and after admission. Of the 81 dementia patients, 65 had Alzheimer's disease, three were dementia patients with Lewy bodies, six patients had vascular type dementia and seven were dementia patients with psychosis (4 schizophrenia, 1 manic depression and 2 mental deterioration). Before being hospitalized, anti-dementia drugs were prescribed as follows: donepezil for 23 Alzheimer's disease and three dementia patients with Lewy bodies, rivastigmine for one Alzheimer's disease patient, galantamine for one Alzheimer's disease patient and memantine for three Alzheimer's disease patients, and a combination of both denepezil and memantine for five Alzheimer's disease patients. Anti-dementia drugs were not prescribed for the other 32 Alzheimer's disease patients, six vascular type dementia patients and seven dementia patients with psychosis. As both rivastigmine and galantamine offer similar effects on acetylcholine as donepezil, the three different drugs – rivastigmine, galantamine and donepezil – were summarized as donepezil analogy, and were given to the donepezil group of 30 Alzheimer's patients (23 donepezil, 1 rivastigmine, 1 galantamine and 5 combination of both donepezil and memantine). Dementia was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. At baseline, we carried out a physical/ neurological examination, Mini-Mental State Examination (MMSE) for cognitive function, Barthel Index for activities of daily living (higher scores indicate better performance) and a brain computed tomography scan. BPSD was assessed using the Neuropsychiatric Inventory (lower scores indicate better performance). After being admitted as inpatients at Sendai Tomizawa Hospital, memantine was continuously prescribed for three Alzheimer's patients who had been prescribed memantine before becoming inpatients. Donepezil was continuously prescribed for three dementia patients with Lewy bodies who had been prescribed donepezil before becoming inpatients. Antidementia drugs were not prescribed for six patients with vascular type dementia and seven dementia patients with psychosis, except some psychotropics if necessary. After becoming inpatients, anti-dementia drugs were not prescribed for 32 Alzheimer's disease patients who had not been prescribed anti-dementia drugs before becoming inpatients (group A). Among the 30 Alzheimer's disease patients who had been prescribed donepezil analogy before becoming inpatients, 14 patients had been continuously prescribed the donepezil analogy, including three patients who had been prescribed both donepezil and memantine before becoming inpatients (group B), but as the other 16 patients showed extremely intolerable BPSD, such as asking to be discharged from hospital, resistive attitude to care workers, abusing families, crying and restless attitudes, the denepezil analogy was omitted after they became inpatients (group C). Among these 16 patients who had the donepezil analogy (group C), memantine was prescribed in 10 patients, including two patients who had been prescribed both donepezil and memantine before becoming inpatients, and another six patients had not been prescribed memantine. Some psychotropics, but not antipsychotics, have been used for reducing BPSD, if necessary, in all Alzheimer's disease patients. Two weeks after becoming inpatients, BPSD of groups A, B and C changed from 31 ± 18 to 25 ± 14 (n = 32, no significance), from 21 ± 12 to 19 ± 11 (n = 13, no significance) and from 38 ± 18 to 22 ± 14 (n = 16, P < 0.01), respectively (Table 1). There was no significant difference of MMSE or Barthel Index before and after becoming inpatients in groups A, B, and C. Durations of suffering Alzheimer's disease were not Geriatr Gerontol Int 2014; 14: 515–517 bs_bs_banner

This paper concerns finite groups of class (at most) two and of odd prime exponent $p$. Such a group is called special if the center lies within its derived group. Every group of class 2 and exponent $p$ can be uniquely expressed as the direct product of an elementary abelian group and a special group. This reduces the isomorphism problem to special groups. The special groups having $G'$ cyclic are well known. Groups having $|G'|=p^2$ are known to be generated by two abelian subgroups. As such, they can be described by a pair of Scharlau Matrices which we will define. Using these, Vishnevetskii ([1], [2]) classified the special groups which are not central products of groups of smaller order. We call these Vishnevetskii indecomposable. All decomposable groups are central products of two or more indecomposable groups. By Theorem 2 of [2], if $G$ is a special group with derived group of order $p^2$ then the indecomposable central factors of $G$, together with their multiplicities, form a set of invariants for $G$. However these invariants do not determine $G$, since (as we will show below) two nonisomorphic groups can have the same indecomposable central factors. The groups of exponent $p$ and order dividing $p^8$ are already in the literature. In this paper we prove that there are six isomorphism types of special groups of order $p^9$ having $|G'|=p^2$, and we list them.
We will also introduce a way of representing groups of class 2 having exponent $p$ by using digraphs with flows on the edges. The digraph is compact and gives, on sight, a great deal of structural information about the group and completely defines the group. Some group invariants will also be described which are easy to compute from the digraphs and which can readily be used to distinguish the isomorphism types for small orders.


The photoelectrochemical oxidation of nitrite ion on a rutile form of a TiO{sub 2} particulate film immobilized on a titanium plate (TiO{sub 2}/Ti) with applying bias potential was studied. The experimental results indicate that the oxidation of nitrite ion is mainly affected by the applied potential and irradiation of power of light, and the oxidation is also independent of both nitrite ion concentration and pH. Theoretical analysis results correlate well with experimental ones, indicating that the reaction is of zero order with respect to the concentrations of nitrite ion and the hydroxyl ion. Meanwhile, the reaction is of 0.30 and 0.80 order with respect to the applying bias potential and the output power of light, respectively.


The contributions of replacing rye-grass (Lolium spp.) hay with banana (Musa acuminata) by-products on carcass and tissue characteristics, pH and color, in the Canary hair sheep breed were studied. Twenty-two lambs with an initial live weight of 14.8 ± 2.5 kg were individually housed and fed two different diets for 58 days: The first group (experimental diet) received as forage a mixture of fresh banana (Musa acuminata) by-products composed by leaves and pseudo-stem. The other one got commercial rye-grass (Lolium spp.) hay (conventional diet) as a fiber source. The two groups got an additional commercial concentrate food (CON). After the 58 days growing trial (24.3 kg ± 1.0 kg), seven lambs of each group (n=14) were slaughtered in the experimental slaughterhouse. The muscle, the pH, and the color were measured at the time immediately after slaughter and 24 h later, using the muscles Longissimus thoracis et lumborum and semimembranosus. At that time (after 24 h), the remaining semi-carcass was butchered and dissected for analysis of the carcass´s regional and tissue composition. Although there is no significant difference on the tissue composition, carcass regional and the muscle pH, there are significant differences in the color in the Longisimus toracis et lumborum between the two assessed diets. The incorporation of banana by-products in a diet to fatten lambs Canary hair sheep breed would not grossly alter the carcass quality, at least based on the assessed parameters. Banana by-products as a feeding resource can maintain animal productivity and meat quality. © 2021 Friends Science Publishers


Problem statement: Biometric is a unique, measurable physiological or behavioral characteristic of a person and finds extensive applications in authentication and authorization. Fingerprint, palm print, iris, voice, are some of the most widely used biometric for personal identification. To reduce the error rates and enhance the usability of biometric system, multimodal biometric systems are used where more than one biometric characteristic are used. Approach: In this study it is proposed to investigate the performance of multimodal biometrics using palm print and fingerprint. Features are extracted using Discrete Cosine Transform (DCT) and attributes selected using Information Gain (IG). Results and Conclusion: The proposed technique shows an average improvement of 8.52% compared to using palmprint technique alone. The processing time does not increase for verification compared to palm print techniques.


At the outset I think it is important to recognize a fundamental con- ceptual distinction. That distinction is between wildlife as an input into a production process and wildlife as an output valued by hu- mans. The nature of economic goods is such that raw inputs are sel- dom valued for consumption in their original form. Some sort of entrepreneurial talent needs to be applied in order to transform those inputs into valued outputs. Even though the amenity value of wild- life often requires minimal interference with wild populations, the role of the entrepreneur is no less important here than in other pro- duction processes. Perhaps the most characteristic problem faced by a wildlife entrepreneur is how to provide human access to wildlife, so they may be seen and admired, without endangering the resource. In cases of nonamenity outputs, like the production of furs and meats, the entrepreneurial problems are more like those faced by producers of nonanimate goods...

Quantum paradoxes show that quantum statistics can exceed the limits of positive joint probabilities for physical properties that cannot be measured jointly. It is therefore impossible to describe the relations between the different physical properties of a quantum system by assigning joint realities to their observable values. Instead, recent experimental results obtained by weak measurements suggest that nonclassical correlations could be expressed by complex valued quasiprobabilities, where the phases of the complex probabilities express the action of transformations between the noncommuting properties [H. F. Hofmann, New J. Phys. 13, 103009 (2011)]. In these relations, negative probabilities necessarily emerge whenever the physical properties involved are related to each other by half-periodic transformations, since such transformations are characterized by action phases of $\ensuremath{\pi}$ in their complex probabilities. It is therefore possible to trace the failure of realist assumptions back to a fundamental and universally valid relation between statistics and dynamics that associates half-periodic transformations with negative probabilities.


This paper presents Banzai a Java framework that uses the Tatoo parser generator to simplify the implementation of high-performance servers based on plain-text protocols. This approach conciliates the use of formally defined grammars for protocol parsing and the efficiency of the implementation. We argue that the use of the formal grammars simplifies the implementation of the protocol and we show that an HTTP server built using the Banzai framework is as efficient as several existing ad-hoc high-performance HTTP servers. The Banzai framework relies on the ability of Tatoo to produce push non-blocking parsers with a fixed memory footprint during parsing and on a generic and efficient server architecture.
