In bilateral teleoperation, the performance measure has significant considerations: control objective, quantitativeness, time delay and human haptic perception, but no suitable performance measure exist. Therefore this paper investigates extended transparency as a performance measure in bilateral teleoperation. First, through an analysis based on control objective, extended transparency has two independent control objectives: trackability and immersivity. Second, we develop the performance measure for each control objective of extended transparency by using both the transmission delay constant and the error vector magnitude for the effect of time delay, and both the meaningful perception bandwidth and the compliance just-noticeable-difference for human haptic perception. Finally, extended transparency is applied to two kinds of control architecture in a one-DOF LTI teleoperation system. The case study and simulations demonstrate the ease of application and the validity of the proposed method.


The paper investigates some corporate attributes that influence the corporate governance disclosure in Bangladesh. An OLS regression model has been used to analyze the data of 100 sample companies listed either with Dhaka Stock Exchange or Chittagong Stock Exchange in 2004. We find that some corporate attributes such as multinational affiliation, linkage of auditor with big four audit firms, concentrated ownership by sponsor and banking companies influence significantly on corporate governance disclosures.

Agricultural standardized demonstration area represents higher growth level of agricultural output.In this article,the economic growth performance of agricultural standardized demonstration area in Anhui Province was analyzed by using extended cobb-douglas production function(C-D) model.The results show that,there is long-term equilibrium relationship between the number of agricultural standardized demonstration area(NBS),the investment of capital,labor and gross agricultural product(GAP).The output elasticity of NBS is positive,which shows that NBS could bring higher growth of GAP,and the effect will be more significant with construction cost allocation year by year.The contribution of capital to GAP is more remarkable,which demonstrates that either constructing agricultural standardized demonstration area or developing agriculture both need the government to increase input.The output elasticity of labor is negative,which indicates the development of modern agriculture emphasize much more requirement of labor quality and already get ride of traditional expansion of labor quantity based on agricultural standardized demonstration area,and this need will more obvious with further development of modern agriculture.


With the complete transformation of flax production from the planned system to market system,the industrialization of the scientific and technical achievement is hindered seriously.How to advance industrialization of the scientific and technical achievements in flax research is an important topic for the scientific research institutes and production divisions.This article demonstrate clearly the necessity of industrialization of scientific and technical achievement of flax,the state of existing technical achievement and the concrete steps and measures of accelerating the industrialization of scientific and technological achievements,in order to promote the development of industrialization of the flax research achievements and high-efficient intensification of the flax production.


Collapsibility is the sudden reduction in volume of soil due to wetting. A phenomenon attributed to loss of particle-to-particle bonding resulting from mineral dissolution and/or change in stress state triggering particles rearrangement and densification. The initial bonding, providing metastable structure for such soils, is believe to come from either suction, clay minerals, CaCO3, or other salts. Loess, compacted clays, silts and sands are commonly studied collapsible soils. This study investigates the impact of CaCO3 bonding in the collapse of unsaturated calcareous silty-clay soils artificially created using an innovative setup made in-house. Collapsibility studies were carried out using singleand doubleoedometer tests adopting distilled water and a 5% acid solution as collapse triggers at 300 kPa overburden stress. Collapse Potential (CP) measured in terms of percentage height decrease of oedometer specimens after wetting, revealed that where distilled water was applied, lower CP emerged compared to using the 5% acid solution as wetting fluid. Clay-silt ratio, calcareousness as well as dry density were also observed to control the collapsibility of specimens. Double oedometer results indicate that wetting triggered deformation may be independent of loading or wetting sequence, as deformation curves for both 'presoaked' and single oedometer tests align at stress levels above the collapse trigger point.

According to such properties of the dimethyl ether(DME) as high saturated vapor pressure,low viscosity and easy formation of mixture with air,a controllable premix combustion(CPC) low-pressure common rail fuel injection test bench of DME engine is developed.Based on this bench,contributing factors of fuel injection such as common rail pressure,needle lift and engine speed are analyzed during injection process.Hence,the characteristics of low-pressure common rail fuel injection are found; and it promotes the using of DME in low-pressure common rail system.


COVID‐19 is an ongoing pandemic caused by the SARS‐CoV‐2 coronavirus that poses one of the greatest challenges to public health in recent years. SARS‐CoV‐2 is known to preferentially target older subjects and those with pre‐existing conditions, but the reason for this age dependence is unclear. Here, we found that the case fatality rate for COVID‐19 grows exponentially with age in all countries tested, with the doubling time approaching that of all‐cause human mortality. In addition, men and those with multiple age‐related diseases are characterized by increased mortality. Moreover, similar mortality patterns were found for all‐cause pneumonia. We further report that the gene expression of ACE2, the SARS‐CoV‐2 receptor, grows in the lung with age, except for subjects on a ventilator. Together, our findings establish COVID‐19 as an emergent disease of aging, and age and age‐related diseases as its major risk factors. In turn, this suggests that COVID‐19, and deadly respiratory diseases in general, may be targeted, in addition to antiviral approaches, by approaches that target the aging process.


Scholarship on the visual culture in American religions has flourished in the past three decades. Scholars from myriad disciplines have generated essays, monographs, and edited volumes that examine everything from fine art paintings to popular prints, church architecture to yard shrines, and folk art to graphic novels. In this essay, I provide an abbreviated explanation for the explosion of scholarship on visual culture and American religions in the 1980s and 1990s to highlight prominent approaches to the subject in contemporary scholarship. Then, I outline a few of the major themes that stimulate the scholarly field, including popular religion, consumption, cross-cultural encounters, sacred space, modern and postmodern art, and dress. Finally, I consider challenges faced by contemporary scholars in developing and strengthening this interdisciplinary area of inquiry.


Understanding the mechanism of moderate earthquake swarm is important for the time‐dependent hazard assessment. Five Ms ≥ 5.0 earthquakes occurred between October and November 2013 in Qianguo, Jilin, a region with low seismicity in northeast China. After 4 years, two more Ms > 5.0 earthquakes struck Ningjiang, Jilin. To investigate the swarm mechanism and the relationship between these two swarm activities, we determine the full moment tensor solutions for 12 Ms > 3.5 earthquakes, including the seven Ms ≥ 5.0 events. The focal mechanisms show that the 2013 Ms ≥ 5.0 events mostly exhibit thrust compression with significant volume closure components, whereas the 2017 Ms ≥ 5.0 earthquakes illustrate a dominated strike‐slip type. In order to explain such differences, we conduct double‐difference tomography in the study region. Our tomographic results reveal that both swarms are located in the low‐velocity zones and the fault materials exhibit structural variations along the strike, possibly indicating that the structural contrast could be critical for the variations in the focal mechanism and hypocenter migration. The faults provide pathways for the upward intrusion of fluids that control the distribution and migration of the swarm sequences. A long‐term fluid‐rock interaction could lead to the fault materials intensely fractured in the 2013 swarm area but relatively less damaged in the 2017 swarm area. We can conclude that fluids play an important role in triggering the two seismic swarms.


Government agencies have provided funding for integration, and nearly all states require that new teachers have at least some technology training to receive certification. And yet the United States is falling behind technological leaders such as Japan and Britain in its attempts to educate with the aid of technology (Seymour 2). Many educators understand that, to compete in a global market, those entering the workforce must possess technological literacy. We are willing to learn and adapt to better prepare our students. We have read articles and listened to lectures telling us that technology empowers students and deepens their understanding and enjoyment of current curriculum; and we believe it. Yet, integrating technology is a daunting task considering that most public schools still do not have adequate hardware or software to make the widespread use of computers feasible. So, what can we do? Waiting for the optimal learning situation, in which each student has access to a computer, is not a realistic answer. My thoughts turned to a tool I already used frequently in the classroom-group learning. Until schools receive the necessary funding to provide computers for all students, the use of technology and group learning makes a natural marriage. Over 375 studies have been conducted over the past ninety years to determine how successful group efforts are in promoting achievement and enjoyment (Johnson, Johnson, and Smith 73). Teachers with the true desire to meet the technological needs of their students need not despair: technology combined with the comfortable, old-shoe method of cooperative learning can be extolled as a powerful tool. I began using this methodology with a single computer application, PowerPoint, a multimedia tool designed by Microsoft. It allows the user to create a slide show that


Aiming at solving the subjectivity and uncertainty of service quality elements classification in Kano model and combining with fuzzy theory which is effective to cope with uncertainty and ambiguity, a Kano model based on fuzzy theory is proposed. This study will apply an approach of fuzzy questionnaires to modify Kano questionnaires which considered as subjective. Furthermore, this study will also develop a mathematical calculation performance according to the quality classification of fuzzy Kano model. It's more objective than traditional Kano model to realize the service quality elements classification. With this method, the accurate mentality can be fully reasonable reflected in unknown circumstances. Finally, an empirical study in Xuzhou Construction Machinery Group Co., Ltd, the largest manufacturing industry in China, to testify its feasibility and validity.


Stress reactions in marine fish were studied in detrmining the effects of environmental salinity changes on the haematology of the red aes bream, Chrysophrys major TEMMINCK et SCHLEGEL. Acute elevation in environemtal salinity induced hyperglycemia, increase of serum cortisol levels of the fish. The fish exposed to acute salinity lowering showed hyperglycemia, increase of serum cortisol level and high haemeatocrit values with low sodium and chloride levels. It was confirmed that these haematological changes depended on the intensity and the rate of salinity change. The determination of the phases in stress reactions was examined through the use of Euclidean distances calculated by 3 variables; mean haematocrit value, mean glucose level and mean serum sodium level. They were recognized to include control phase, reactive phase where the hyperglycemia was noticeable and exhausitive phase where serum sodium level was remarkably influenced by environmental salinity. These phases were considered to be slightly affected by stimuli-specific reactions of the fish.


Carbon capture technologies are urgently required to reduce carbon emissions and reach the target of net-zero emissions for all countries because the significant amount of CO2 emissions brought on by human activities has contributed to many environmental problems, including global warming and extreme climate. In this paper, the fundamentals of the three primary post-combustion CO2 capture methods—absorption separation, adsorption separation, and membrane separation—are discussed. Additionally, the most recent advancements in these technologies are discussed. The paper also compares the benefits and drawbacks of each of the three technologies, emphasizing a number of difficulties and challenges currently faced by each of the three carbon capture technologies, including high cost, high energy consumption, low stability and low selectivity. Finally, the development prospects and research priorities of the three carbon capture methods are analyzed, and it is indicated that the primary paths for the advancement of carbon capture technologies in the future will be cost reduction and rapid commercialization and industrialization.


This research is motivated by the phenomenon of early childhood problems caused by low self-concept. Self-concept is a person's perspective, including understanding, assessment, and expectations of himself regarding both physical, psychological, and social self. Self-concept can form the cognitive structure of students to do something either take positive actions or take negative actions. Students who have a positive self-concept show good achievement in school, or high-achieving students in schools have high self-ratings and show positive interpersonal relationships. Students are able to determine realistic learning achievement targets and direct academic anxiety with hard and diligent learning, and student activities are always directed at learning, and not dependent on the teacher.


The synchronous firing of dense and strongly ionized plasmas with the time structure of bunched and energetic multicharged ion beams allows to probe for the first time, the long searched enhanced plasma stopping and the enhanced projectile charge at target exit, as well.


The title of this article, 'shababbery and banattitude', is based on words I invented during the years I spent working in English language teaching (ELT) in countries of the Gulf Cooperation Council (GCC). As a male teacher of British background I have, since 1994, taught mixed-gender classes of Kuwaiti oil workers, large, all-male classes of Saudi college students and all-female classes of Emirati college students; in the process I was exposed to a range of gender combinations and was accustomed to the type of gender-related comments that would be commonly aired in the teachers' room by my colleagues.


Recently, attention has focused in Israel on the possible legal and health consequences of shift work. We decided to study sleep disorders among female nursing personnel working a shift schedule, in comparison with day nurses, in a large metropolitan general hospital. The study population was composed of 131 female certified nurses working shifts and 44 working days only. Inclusion criteria for the survey was at least 1 year of shift work alternating between day, evening, and night shifts, or at least 1 year of day work. All participants completed a self-report sleep questionnaire encompassing (a) demographic data, (b) sleep survey, and (c) employment details. Statistical analysis was performed using the Pearson correlation test and analysis of variance multiple range test (according to Scheffe's procedure). No significant correlation was found between sleep disorders and age of subjects. No sleep disorders were reported by 19.8% of shift workers versus 76.5% of day workers. Statistically significant find...

As most regular readers of this TRANSACTIONS know, the development of digital signal processing techniques for applications involving image or picture data has been an increasingly active research area for the past decade. Collectively, t h s work is normally characterized under the generic heading "digital image processing." Interestingly, the two books under review here share this heading as their title. Both are quite ambitious undertakings in that they attempt to integrate contributions from many disciplines (classical systems theory, digital signal processing, computer science, statistical communications, etc.) into unified, comprehensive presentations. In this regard it can be said that both are to some extent successful, although in quite different ways. Why the unusual step of a joint review? A brief overview of the two books reveals that they share not only a common title, but also similar objectives/purposes, intended audiences, structural organizations, and lists of topics considered. A more careful study reveals that substantial differences do exist, however, in the style and depth of subject treatment (as reflected in the difference in their lengths). Given their almost simultaneous publication, it seems appropriate to discuss these similarities/differences in a common setting. After much forethought (and two drafts), the reviewer decided to structure this review by describing the general topical material in their (joint) major sections, with supplementary comments directed toward the individual texts. It is hoped that this will provide the reader with a brief survey of the books' contents and some flavor of their contrasting approaches. To avoid the identity problems of the joint title, each book will be subsequently referred to using the respective authors' names: Gonzalez/Wintz and  Pratt. Subjects will be correlated  with chapter  number(s) and approximate  l ngth of coverage.


This paper reports the results of studies of ZnS/Ge/ZnS nanostructures, obtained by high vacuum thermal deposition of ZnS and Ge powders into porous anodic aluminium oxide (AAO) with different diameters of pores. Scanning electron microscopy (SEM) investigations reveal two types of nanostructures having the form of rings (sample with diameter of pores 70 nm) and rods (samples with diameter of pores 80 and 110 nm). It is also shown that the other porosity parameters such as interporous distances affect the formation of a particular type of nanostructures. X-ray and electron diffraction study show two phases, ZnS and Ge. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)


Hydrocarbon polymerization in the presence and absence of oxygen is one of the major problems in industries due to the exothermic characteristic of spontaneous decomposition of polymers. In addition, the presence of unwanted polymers reduces process efficiency, can lead to pipe breakage and increases maintenance intervention costs. Many actions can be taken to minimize the effects caused by polymerization, most of them corrective, such as opening pipes for physical removal of polymers through hydroblasting and opening of tanks for mechanical cleaning. The main preventive action is the installation of an inhibitor dosing system. There are several substances that can act as inhibitors known, and the choice of the best inhibitor will depend on operating conditions, the appropriate inhibition mechanism and the cost of use. In this work three alternatives were proposed for installing a polymerization inhibitor dosing system in butadiene storage tanks of a synthetic rubber industry. The "popcorn" polymer formed through the stored butadiene oxidation mechanism has a high risk if exposed to sunlight due to its self-igniting capacity and only in 2019 represented a cost of R$ 120,000.00 with unplanned maintenance, such as unobstructed maintenance of shipping line for boilers, rupture disk tank repairs and excessive burning of natural gas in boilers due to unavailability of butadiene fuel line. It was found that the best alternative would be a closed dosing system using a transfer vessel and nitrogen for inertization and pressurization. The inhibitors used will be a substituted alkylamine and tert-Butylcathecol, with free radical inhibition mechanism and oxygen sequestration, respectively, being two complementary mechanisms, increasing the protection power of stored butadiene. With this implementation it is estimated a saving of R$ 360,000.00 in the consumption of natural gas in the boilers, besides the maintenance costs


Near the bottom of the circles of the violent, at the edge of the abyss separating the realm of the sins of wrath from the realm of the sins of fraud, Virgil commands Dante to take from his waist a cord with which he "had once thought to take the gay-skinned leopard." Virgil drops the cord into the abyss, and slowly there flies up into the poets' view and ours one of the most fantastic of Dante's monsters, Geryon, the emblem of Fraud. Dante implores the reader for his belief (Inferno XVI, 124-30, and Singleton's translation):


The magnetic tunnel junction (MTJ) based molecular spintronics device (MTJMSD) approach is suitable for mass production. This approach provides solutions to fabrication difficulties related to reliably connecting molecular device elements to the ferromagnets (FMs). To producing MTJMSD, the molecular channels are bridged across the insulator of an MTJ testbed with exposed side edges. In an MTJMSD, two FMs are simultaneously connected by an insulator film and the molecular channels along the exposed sides. In our prior experimental studies, we observed that molecules could produce strong coupling between ferromagnets in the presence of the competing coupling via an insulator. In this paper, our Monte Carlo Simulation (MCS) was used to study the impact of coupling variation via insulator (a.k.a. Ji) on the magnetic properties of an MTJMSD. We studied the effect of Ji while varying the molecule induced antiferromagnetic exchange coupling. The ferromagnetic or antiferromagnetic nature and magnitude of Ji determined the resultant effect. Antiferromagnetic Ji enhanced the pre-existing antiferromagnetic molecular coupling effect. Ferromagnetic Ji competed with the opposite nature of antiferromagnetic molecular coupling. Our MCS may help to understand the impact of insulator thickness and defects on the molecular spintronics device performance and design process.


Parthenium density and species richness were found to be more in non-invaded (N-I) sites as compared to invaded (I) sites of Jaunpur district. pH, OC and %N of the soil indicates that the plant survive naturally at higher level of salinity. In pot experiment, plant growth, proline content, TSS content, chlorophyll, N, P and K was not significantly affected up to 1% NaCl (w/w) over the control after 30 and 60DAS. BCF for parthenium plant was >1 up to 2% NaCl treatment. Bacterial population was more in rhizospheric soil then rhizoplane soil under NaCl after 30 and 60DAS, and indicates bacterialrhizoadaptation. Hence, the parthenium plant able to improve soil health and might be useful in the field of restoration ecology.


Sleep paralysis is considered as a dissociated state during which rapid eye movement sleep related muscle atonia appears while a subject is fully awake. We present a 22-year-old man and a 19-yearold man diagnosed with narcolepsy who previously visited our clinic with phenomenon of sleep paralysis. When a patient is brought to the clinic with sleep paralysis, various physiologic and medical conditions such as stress, trauma, hereditary factors, physical health, sleep disorders and other psychiatric disorders are taken into consideration. Prevalence of sleep paralysis in narcolepsy patients is known to be 20–50%. Therefore, it is necessary that clinicians should carefully examine the presence or absence of narcoleptic symptoms when dealing with patients with sleep paralysis and should conduct the multiple sleep latency tests confirm the diagnosis of narcolepsy if necessary.

In the paper,the cationic starch was synthesized with cornstarch methacryloyloxyethyl trimethylammonium chloride (DMC) and acrylamide (AM) by radical copolymerization with special technology.A series of cationic starches were synthesized by varying the amount of the starch and the ratio between DMC and AM.The cationic starches were characterized and analyzed by IR and 13 C-NMR.The reinforcing effects of the cationic starch on eucalyptus pulp were studied.The results showed that the reinforcing effects of the cationic starch were closely dependent on its molecular structure.


It is well known that there has been a steady and significant underrepresentation of women in philosophy on different professional levels. Numerous hypotheses explaining this underrepresentation have been suggested, but empirical analyses are not yet extensive. In particular, studies of the phenomenon in different countries are nonexistent. In this paper, we present findings from an exploratory study in which we analyze the interests, abilities, beliefs, attitudes, perceptions, and goals of bachelor's students in a semester-long philosophy of science course at a major German university. We furthermore make the first attempt to compare women-only learning environments with mixed-gender learning environments. Our results suggest that while there are generally some gender differences regarding interests, abilities, beliefs, attitudes, perceptions, and goals of students in the classroom, most of the hypotheses we explore to explain dropout rates by gender differences cannot be supported. We conclude that possible factors leading to the underrepresentation of women in philosophy in Germany might be found in the social and institutional environment within which philosophy is taught.


this between the ir interests, and the role that MCRs play in the social - economic plans of countries. The key findings are that investments in MCRs are mainly in the Science, Technology, Enginee r ing and Mathematics ( STEM ) and Education sectors, and have taken place mainly in high- income countries and regions – contexts that particularly value practice-a ccredited MCRs. L ow - income countries, by contrast, remain traditional and insist on MCRs that are formally accredited by a recog-ni zed academic institution. This contributes to a widening skills gap between low - and high- income countries or regions, which results in greater global dis-parities. There is also a growing divide between academia and practice concern-ing their interest in MCRs (a reflection of the rigor versus relevance debate), which partially explains why many global and larger organizations have gone on to create their own learning institutions. of as of innovative efforts for life - wide (different sectors) and life long (same sector) learning, especially in low - income countries. MCRs provide dynamic mechanisms to fill skills gaps in an increasing ruthless international battle for talent The study proposed a full - text search framework based on the pub-licly available metadata on the Hyperledger "Indy ledger" for re-trieving matching credential types. The proposed solution is able to find credential types based on textual input from the user by using a full - text search engine and maintaining a local copy of the ledger. The study highlights six broad possibilities to implement micro -cre-dentials in undergraduate programs across the university. It includes micro -credenti al design and assessment principles, information pack and platform as well as outlin ing the student's journey in each of the phases involved in the micro - credential ecosystem. The study proposed a blockchain - based solution, 'CredenceLedger', which stores compact data proofs of digital academic credentials in a blockchain ledger , making these easily verifiable by education stakeholders and interested third party organizations. The findings showed that the most common barriers to widespread educational innovation can be framed as credentialing issues, whether as excuses for not implementing change or as legitimate obstacles. At the root of the credentialing issue is the ubiquitous standard unit of effort – the credit hour, which was originally designed simply to measure faculty workload rather than student learning. The se authors investigated whether there were differences in self control, persistence, and social relationships among youth with a di-ploma, a GED, or no credential. They the n investigated whether and how self - control, persistence, social relationships, dropout status, and educational attainment related to young adults' employment outcomes. Results indicate differences in self - control, persistence, and social support among the three groups. Models indicate a non- linear relation between self - control and persistence to employment outcomes, and highlight the importance of educational attainment. of - credentials. The findings The report examines pilot studies on accrediting competencies gained in non- formal education using micro -credentia ls and digital badges, and reports on the results of those efforts. A proposal on how to accredit the competencies using an open badging system is formulated. This report looks at 17 credential categories offered by four types of education providers: postsecondary educational institutions, massive open online course (MOOC) providers, non - academic organizations, and secondary schools. Postsecondary institutions were found to be the largest type of credentialing organization, closely followed by non - academic organizations. This paper suggests that a model for life - wide learning awards where the assessment activities are devolved to trusted third parties would help to reduce the burden on students and staff. The idea of open badges, a standard for creating and sharing secure, verifiable digital credentials and evidence, is proposed and discussed using a case study as a means to support a devolved approach to life - wide learning awards. The that generally This study provides requirements for designing digital credential wallet design and recommends guidelines on key management of a consultative process on the implementation of


The income gap between urban and rural areas is one of the most prominent contradictions in the social and economic development of China. Based on the literature review,researching the factors that affect the income gap between urban and rural areas is mainly through theoretical explanations and empirical analysis. Theoretical analysis indicates that the reasons for the income gap between urban and rural areas include urban bias policy,excessive pursuit of economic development and dual structure "center- periphery". The results of Panel Data empirical model estimation show that the income gap between urban and rural areas is affected by economic development,policy bias,financial development,economic intervention and other controlling factors. Some factors that can reduce the urban-rural income gap in general include urbanization,economic openness,human capital,agricultural economic development and the development of tertiary industry. However,other factors that can expand the income gap between urban and rural areas are spending on science and education,public service spending,financial development scale and the development of tertiary industry. Therefore,the elimination of income gap should strengthen the development of rural vocational education,pro-mote the urbanization and construct inclusive development policies and effectively achieve the integration of urban and rural development.


This article probes Mr.Li Keran's connections with the historical culture of Xuzhou,the former Pengcheng Arts Clique,Xuzhou Academic School of Arts,and the artistic field of Xuzhou after liberation.It also describes his great influence on the developing process of arts in Xuzhou in the twentieth century as well as the important role he has played in the formation and development of the Pengcheng Arts Clique.


Building on previous research showing a negative relationship between conservatism and creativity, the present investigation focused specifically on religiosity in the context of the United States. Because of the association between conservatism and religiosity, creativity might have a negative association with religiosity, too. To this end, individuallevel and regional data were matched by linking responses to psychometric measures such as Attitudes and Values toward Creativity to regional data such as church attendance. These analyses controlled other regional variables including education, diversity, and socio-economic status. Two-level analyses with individual data at Level 1 and county data at Level 2 indicated that people from more religious locations held less positive attitudes and values toward creativity and rated their environment as less creative. On the other hand, creative personality, ideational behavior and creative achievement were not significantly related to religiosity. Those analyses provided evidence that creativity and religiosity have a negative relationship in terms of people's attitudes and values toward creativity as well as their perceptions of environment for creativity. Findings were discussed in terms of types of religiosity and other socio-cultural variables.


Molecular nonlinear optical (NLO) crystals feature important advantages compared to inorganic counterparts, such as low dielectric constants, ultrafast response times, and large electro‐optic coefficients. Conjugated push–pull chromophores connecting electron‐donating with accepting groups are often employed in the design of these crystals. However, associated large molecular dipole moments induce antiparallel or centrosymmetric conformations in the solid‐state, which leads to NLO inactivity. The cation–anion hydrogen bond interactions of a hydroxy‐piperidino electron donor group are combined with increased van der Waals volume effects induced by an ethyl modification of the electron‐accepting moiety. This produces non‐centrosymmetric packing in the organic salt EHPSI‐4NBS ((E)‐1‐ethyl‐2‐(4‐(4‐(hydroxymethyl)piperidin‐1‐yl)styryl)‐3,3‐dimethyl‐3H‐indol‐1‐ium 4‐nitrobenzenesulfonate). Converting a methyl group into ethyl changes the packing symmetry in the molecular crystal to switch on NLO activity. This behavior is attributed to the increased size of the ethyl group, which pushes apart the van der Waals contacts of the cation that lead to centrosymmetric packing in the methyl derivative. To test the NLO properties of EHPSI‐4NBS, THz generation experiments are performed at 1200 nm pump wavelength. Spectral amplitude similar to DAST ((E)‐4‐(4‐(dimethylamino)styryl)‐1‐methylpyridin‐1‐ium tosylate) crystal is observed with generation profile from 0 to 3.8 THz.


Objective To evaluate the results of TSRH instrumentation in the correction of frontal,sagittal and axial plane deformity of scoliosis. Methods From January 1998 to June 1999, thirty-two consecutive patients with scoliosis underwent anterior or posterior spinal instrumentation and fusion using TSRH instrumentation. There were 6 males and 26 females, with an average age at the time of surgery of 16. 4 years (range, 11- 45). Twenty-one cases were idiopathic scoliosis and 11 cases were congenital. The preoperative curve measurement showed an average of 71. 2° (range, 44° - 125°), and 49. 2° (range, - 16° - 67°) in frontal and sagittal respectively, while axial plane deformity (Nash - Moe) ranged from Ⅰ to Ⅲ degree. Preoperative trunk shift averaged 4. 8 cm (range, 3 - 9 cm). Results All the patients were followed-up for an average of 9. 7 months (range, 6 - 24 months) after operation. The averaged frontal curve measured 26. 6°(range, 10° - 73°), a 63. 8% curve correction. Sagittal contours were well maintained by this instrumentation, thoracic kyphosis measured an average of 28° (range, 10° - 45°). Rotation of the apical vertebrae improved by an average of 1 degree. Postoperative trunk shift averaged 1. 6 cm (range, 0. 5 - 5. 0 cm), a 66. 7% average correction. Two patients had complications: superficial infection of incision and lower hook dislocation developed in each respectively, which accounted for 3. 1 % of the total. No neurologic deficit and pseudoarthrosis occurred in this series. Conclusion TSRH instrumentation may provide the three-dimensional correction, not only for the frontal and rotatory correction, but also well maintained sagittal contour. Fusion occurs reliable because of the stiffness of the construct, which also may eliminate the need for postoperative immobilization with a plaster cast and a lower rate of complication.

This article presents a new method in determining long train derailment. A new strategy for building train models with large number of wagons has been developed. Previous studies have shown that in a train model, some of the details in the model of the wagons neighboring the wagon under study play minor role in dynamic behavior of the spotted wagon. To reduce the size of the overall model, one would tend to eliminate some of the details of the complex neighboring model having minor effect on overall behavior and trade a small approximation in results for large saving in computation time. In this research this idea is used to develop a train model with one full detail wagon model linked in a train model with a large number of wagons having 3 degrees of freedom. The 3 degrees of freedom wagon models are considered to have yaw, lateral and longitudinal motions. The detailed wagon model has 48 degrees of freedom including nonlinear springs, dampers and friction on sliding surfaces. Nonlinear equations of motion for train were developed using Newton-Euler method. The model was then used to simulate train behavior in passing a bend or applying severe brakes at different speeds. The results show very good agreement with the results of models with full degrees of freedoms in all wagons. The computation time is tremendously decreased in the new method.© 2008 ASME


We revisit the shortest path problem in asynchronous duty-cycled wireless sensor networks, which exhibit time-dependent features. We model the time-varying link cost and distance from each node to the sink as periodic functions. We show that the time-cost function satisfies the FIFO property, which makes the time-dependent shortest path problem solvable in polynomial-time. Using the $\beta$-synchronizer, we propose a fast distributed algorithm to build all-to-one shortest paths with polynomial message complexity and time complexity. The algorithm determines the shortest paths for all discrete times with a single execution, in contrast with multiple executions needed by previous solutions. We further propose an efficient distributed algorithm for time-dependent shortest path maintenance. The proposed algorithm is loop-free with low message complexity and low space complexity of $O(maxdeg)$, where $maxdeg$ is the maximum degree for all nodes. The performance of our solution is evaluated under diverse network configurations. The results suggest that our algorithm is more efficient than previous solutions in terms of message complexity and space complexity.


Aspergillus flavus produces potent mutagenic and carcinogenic polyketide-derived secondary metabolites known as aflatoxins. Development of host plant resistance in peanut and other crops is the most environmentally friendly and cost-effective method to eliminate the serious problem of aflatoxin contamination in grains. To confirm that putative peanut genes identified in a previous microarray study were involved in peanut resistance to A. flavus infection, 14 genes were selected for further investigation through real-time PCR. The results revealed diverse patterns of gene expression during seed germination after A. flavus inoculation. Based on the expression levels and the relative-expression patterns over a 7-day period, the 14 host genes could be classified into six different groups belonging to three main biochemical and genetic defence processes of lipid metabolism, oxidative signalling and cell-wall synthesis during counter-attack. A network of gene expression patterns was activated in sequential order in response to A. flavus invasion in both resistant and susceptible peanut lines during seed germination. Understanding gene expression patterns in peanut will be useful to breeders and other scientists interested in incorporating genetic resources of resistance against A. flavus into peanut germplasm and/or commercial cultivars via conventional and/or molecular methods.


171 boys and girls in Grade 4 from schools in three different socio-economic areas were tested on a hand-dynamometer task to determine the effects of social norms on level of aspiration. One-half of the subjects received high social-norm feedback (failure), while the other half received low social-norm feedback (success). Analysis of variance of discrepancy scores indicated that rural girls' aspirations were significantly lowered in the success situation and inner city girls' aspirations were significantly raised in the failure situation. Social norms had greater influence on girls' than boys' aspirations for performance. The results suggest that elementary school children's level of aspiration can be altered through social-norm anchoring, but the nature of these changes varies according to the sex and socio-economic status of the child.


Narrowband, active monolithic-microwave-integrated-circuit (MMIC) filters at X-band are discussed. Results for both bandpass and notch circuits fabricated using standard GaAs MESFET processes are presented. A novel master-slave control circuit provides compensation for fluctuations in the fabrication process and operating temperature, and it enables the filter to accurately track a reference signal.<<ETX>>

A 45-year-old man with a long history of bronchial asthma was admitted to the National Cardiovascular Center with complaints of severe pain, swelling, and ecchymoses of the lower extremities. A diagnosis of Churg-Strauss syndrome was made because of marked eosinophilia, vasculitis, and a history of asthma. Urinalysis revealed severe proteinuria and microscopic hematuria. A renal biopsy demonstrated extensively crescentic glomerulonephritis. The antineutrophil cytoplasmic antibody against myeloperoxidase (MPO-ANCA) level, determined by enzyme-linked immunosorbent assay (ELISA), was 494 ELISA units. Under treatment with prednisolone, the symptoms and eosinophilia improved within 3 days. The MPO-ANCA level decreased to its lowest value, and renal function was ameliorated within 3 months. The patient has been followed regularly on an ambulatory basis with a regimen of prednisolone.

A historical review of the development of cytomegalovirus hyperimmune globulin (CMV‐IG, CytoGam®) shows its increasing use in solid organ transplant (SOT) recipients, either alone or in combination with ganciclovir. A review of clinical trials of CytoGam in renal transplant recipients shows reductions in CMV‐associated syndromes and fungal and parasitic superinfections, and increases in graft survival, while CytoGam prophylaxis trials in orthotopic liver transplant (OLT) recipients have produced reductions in severe CMV‐associated disease and invasive fungal disease. A combination of CytoGam plus ganciclovir in OLT recipients has resulted in reductions in CMV hepatitis and infection, and CMV disease and viremia, plus a trend in improved 1‐ and 2‐year survival rates.


In view of the fact that the UAV patrol overhead transmission line cannot accurately locate the patrol UAV, the relative position of the field source cannot be judged, and the problem of autonomous navigation and obstacle avoidance cannot be realized. A field based on electric field information array detection is proposed. Source location algorithm. Firstly, based on the principle of electrostatic induction, the portable power frequency electric field sensor detection plate is designed. The four sensor detection plates are installed on the same horizontal surface of the drone with the coordinate center of the unmanned aerial vehicle center as the fixed coordinate system. By analyzing the geometric relationship of the spatial position of the four sensors and the corresponding output signals, the relative position coordinates of the field source space can be solved, so as to accurately locate the spatial relative position of the field source and the patrol UAV. The UAV can provide a reference for autonomous navigation and obstacle avoidance. The algorithm solves the problem that it is difficult to achieve accurate positioning and navigation due to factors such as too small wire diameter, weather conditions, and sensor limitations when the patrol drone is far away from the operator. At the same time, a reliable method is proposed. The algorithm can restore the trajectory of the UAV in the laboratory environment, and verify the accuracy of the field location algorithm. It provides a theoretical basis for the research of UAV autonomous obstacle avoidance navigation.


Information and communication technology in schools can be used as a marvelous communication tool to improve better teaching techniques. With the advancement of technology in education, schools adopt school communication software to transmit, store, share or exchange information. In this technological era, ICT in education has compelled many educational institutions to get accustomed to smart technology and make use of computers, the internet, and multimedia as the medium of communication. Technology is application of scientific knowledge for practical purposes in day to day life. It is a science of techniques and methods of doing things related to any art, science or to a particular profession. Information and Communication Technology (ICT) has influenced all aspects of life of individual. It plays a pivotal role in the field of education. Teacher, Student, administrator and every people related to education are popularly used ICT Teacher use ICT for making teaching learning process easy and interesting. In modern societies education demands more knowledge of ICT and also the skills to use ICT in teaching —learning process. The knowledge of ICT also required for teacher to know the world of technology in a better way by which it can be applied for the betterment of the students. ICT is an effective tool for assimilating processing and disseminating information. The main purpose of the study is to know the usages of ICT among Teachers working in B. Ed College. In the present study descriptive survey method was employed by the investigators. The sample consisted of 40 teachers working in B.Ed. College. The results found that the level of usages among teachers is satisfactory and there is no significant difference is found in usage of ICT in relation to gender.


Spontaneous imbibition (SI) is one of the primary mechanisms of oil production from matrix system in fractured reservoirs. The main driving force for SI is capillary pressure. Researches relating to SI are moving fast. In the past few years, amount of literature on the development of SI with respect to many variables, such as mechanism of imbibition, scaling of imbibition data and wettability of matrix blocks. In this review, we first introduced the fundamental physics mechanism of SI through capillary tube models and micromodels. Then both conventional and more novel experimental methods of measuring oil production are discussed thoughtfully. This is followed by reviewing the oil production performance under various boundary conditions and the characteristic length in scaling equations that have been used to account for different cores shape and boundary conditions. The effect of fluid viscosity on the rate of oil production and final oil recovery as well as the development of viscosity term in the scaling equation are reported. The commonly used methods to quantitatively evaluate the wettability of cores and the SI under mix- and oil-wet conditions are introduced. And last but not least, the methods and mechanism of wettability alteration for enhanced oil recovery in mix- or oil-wet fractured reservoirs are presented.


Cooling rate plays an important role in thin wall ductile iron solidification, due to their thickness. Casting simulation is use as a tool to estimate the cooling rate. In the other hand, every microstructure has its own cooling rate. This paper explores the similarity of solidification mechanism between simulation and graphite characteristics. Three types of casting design simulated and produced. Solidification mechanism is analyzed based on cooling rate sequence and trend line matching. Temperature gradient and thermocouple function represent simulation while graphite characteristic represent experiment. The result shows that similarity in solidification mechanism is not found between simulation with experiment due to lack of parameters in both sides.


Introduction: COVID-19 pandemic has been a curse for cancer patients. The lack of understanding and unawareness in handling cancer patients during this pandemic has worsened their conditions. To analyze the real-world scenario, we studied 13 patients who were given immunotherapy during this COVID pandemic era and tried to analyze their outcome or any serious adverse effect that they suffered. This was a pilot study which would pave the way for further bigger studies in future. The aim of the study was to collect the details of patient receiving immunotherapy during COVID-19 pandemic. The data collected included the diagnosis, certain investigations, and the effects of the immunotherapy drugs and its side effects. Results: During this COVID pandemic period starting from March 20 to June 20, we have been regularly giving immunotherapy drugs such as nivolumab, pembrolizumab, and atezolizumab to our patients. We had given six patients nivolumab, six patients pembrolizumab, and one patient atezolizumab. Of the 13 patients who continued to receive immunotherapy in COVID pandemic era, 4 patients were receiving immunotherapy for lung cancer, 3 for head-and-neck malignancy, 2 for relapse lymphoma, and 1 each for hepatocellular carcinoma, renal cell cancer, malignant melanoma, and soft-tissue cancer. One of the patients receiving atezolizumab had actually progressed after receiving pembrolizumab. There was no Grade 3 or 4 toxicity to these drugs and most of our patients continued to be in stable disease/partial remission. One patient had died just after receiving one cycle of nivolumab. Conclusion: COVID-19 infection has posed an unforeseen predicament both for the patients and the treating oncologist. In absence of any previous data, it is very difficult to manage cancer patients where the treatment itself is thought to harm the patients. This is a humble effort to bring to the notice of the world that immunotherapy can be continued during COVID pandemic, provided we take all due precautions.


According to a triopoly game model in the electricity market with bounded rational players, a new Cournot duopoly game model with delayed bounded rationality is established. The model is closer to the reality of the electricity market and worth spreading in oligopoly. By using the theory of bifurcations of dynamical systems, local stable region of Nash equilibrium point is obtained. Its complex dynamics is demonstrated by means of the largest Lyapunov exponent, bifurcation diagrams, phase portraits, and fractal dimensions. Since the output adjustment speed parameters are varied, the stability of Nash equilibrium gives rise to complex dynamics such as cycles of higher order and chaos. Furthermore, by using the straight-line stabilization method, the chaos can be eliminated. This paper has an important theoretical and practical significance to the electricity market under the background of developing new energy.


States and international institutions have committed, through the adoption of the Sendai Framework, to promote and protect all human rights, whilst managing the risk of disasters. To this end, the relevance and application of international human rights instruments – particularly the International Covenant on Economic, Social and Cultural Rights, with this chapter focusing on the right to health – are a critical consideration in the adoption and implementation of State Disaster Risk Reduction (DRR) strategies. Moreover, States have committed to facilitate, and even request, the assistance of international actors, including the International Federation of the Red Cross (IFRC), in their DRR strategies, including practical support in the aftermath of disasters.
It is posited that where states do not fully meet their human rights obligations, (but importantly, even where they are actively progressing these), non-state organisations such as the IFRC and Red Cross National Societies could assist in progressing these obligations and bridge any gaps through their humanitarian and DRR related roles, whether by design or not. This argument is illustrated by the Nepal earthquake, as Nepal is an example of a state with little DRR legislation but plenty of policy. It focuses on the plight of women in need of emergency healthcare during the earthquake.
Ultimately, the chapter shows that States may be unable to reach even the 'minimum core' of the ICESCR in the aftermath of disasters but co-ordination of resources and support from external actors should take into account the human rights protection needs of the affected population.


The vacuum preloading method is commonly used to improve soft soils; however, it has rarely been studied from the perspective of energy consumption. The work done by the vacuum pump in the vacuum system can be consumed in various manners, including the seepage consolidation of soil, water discharge along prefabricated vertical drains and horizontal drainage system (i.e., the sand blanket or horizontal pipes), extraction of the air sealed in the drainage system, and air leakage from the atmosphere. Equations governing these aspects of energy consumption were derived in this study. A theoretical model of the energy consumption of the vacuum preloading method was established and then solved to quantify the specific forms of energy consumption. Theoretical predictions and laboratory results demonstrate that the energy consumptions of seepage consolidation and water discharge are negligibly small compared with the total work by the vacuum pump, and most of the work done by the vacuum pump in the vacuum system is consumed during the extraction of leaked-in air.

Backgrounds: Docosahexaenoic acid (DHA), which is mainly derived from marine fish, is suspected to reduce the risk of dementia and cognitive decline. The associations of fish consumption and DHA with the scores of Kana Pick-out test (KPT), a cognitive function test to detect pre-dementia, were examined in a remote island of Kagoshima, Japan. Subjects and Methods: As a part of an annual health checkup of residents, a questionnaire survey, hair sample collection, and the KPT were conducted in a remote island of Kagoshima during September and October, 2007. Out of 1,188 residents taking a health checkup, 505 (224 men and 281 women, age 30-69), who received all examinations, were analyzed. Among of them, serum samples from 424 subjects were available for a free fatty acid assay. Hair mercury level was analyzed by cold vapour atomic absorption method, and serum free fatty acid level was measured by gas chromatography. Multivariate linear regression analysis was used to calculate the age-, sex-, and education-level-adjusted KPT scores among different levels of mercury and the ratios DHA to arachidonic acid (AA). Results: The average of KPT score in women (38.1) was higher than that of men (35.0, p<0.001). The scores decreased with age (p<0.001) and lower education levels (p<0.001) in both men and women. After adjusting for the effects of age, sex, and education level, KPT score was positively related to the DHA/AA (p for trend = 0.034) in the subjects under the age of 60 but this tendency was not observed in those aged 60 or older. Conclusion: The present study suggested a potential benefit of DHA on cognitive function in the subjects under the age of 60 but further studies for the elderly people are required.


The Sustainability Science Team (SST) of the U.S. Department of Agriculture (USDA) Forest Service Sustainable Operations Initiative is a 18-member virtual research and development team, located across five regions and four research stations of the USDA Forest Service. The team provides research, publication, systems analysis, and decision support to the Sustainable Operations program of USDA Forest Service Business Operations. This report examines the role of the SST in supporting ongoing agency developments in the emerging field of sustainability science. We provide an overview of current areas of research, including the broad themes of resource consumption, energy efficiency, and organizational change to promote sustainability. We review the mandates and structure of current programs and identify future opportunities. Six environmental footprint areas have been identified to guide activities of the SST: energy, water, waste, transportation, purchasing, and leadership. These six areas have been incorporated into the team's research on life-cycle analysis, footprinting, cost-benefit analysis, return-on-investment analysis, assessment protocols, systems analysis, knowledge management strategies, and behavior-change impact analysis.


A new, self-conscious trend in the sociology of science has recently arisen, declaring the contents of science to be its province. It holds that everything in science, from would-be observational statements to the most recondite and abstract theories, is human and social, and as such, be it true or false, subsumable under sociological explanation. Scientific knowledge, it is claimed, even if it is at all about the external world, is the outcome of negotiations between interested parties, the contingent product of a social process of construction. Two approaches can be distinguished within this relativist sociology of science. One focuses on the process of negotiation on the macro-level and studies the formation of scientific consensus through publications. A second, more recent, tendency has shifted its interest to the micro-level, and studies the formation of scientific knowledge in the laboratory. Karin D. Knorr-Cetina's The Manufacture of Knowledge: An Essay on the Constructivist and Contextual Nature of Science' is doubtless the boldest and most consequential attempt to state the case for this latter approach so much so, indeed, that it provides a convenient and welcome

The aim of this work is to realize a revision of the anterior limb lymphatic draining of the Dasypus novemcinctus novemcinctus. 15 armadillos clinically healthy, male and female were utilized; they had been captured in the Argentine Northeast and were injected by the Gerota's Paste  modified method. The injection was realized at the fourth toe level on the medial side as well as on the lateral one; on the interphalangeal area, and on the left one over the manmary gland of both sides. The classical dissections were carried out with a surgery microscope, of Varimex type. The microphotographs were realized with a Zeiss microscope. The exhaustive analysis of the anterior limb area showed the following conclusions: the lymphatic circulation was observed from the distal extremity of the injected area to the axillar lymphocenter from where emitted 2 or 3 efferent lymphatic vessels; they were directed to the superficial inguinofemoral lymphonodule. The limphonodule situated by the scapula caudal border received one efferent lymphatic vessel which came from the superficial cervical lymphonodule and another efferent lymphatic vessel which led to the axillar lymphocenter.


This article documents macro-level trends regarding gender equity for women managers in paid workplaces and examines the importance of factors related to equitable promotion. Primary evidence is drawn from 1982, 2004 and 2010 surveys of work and learning activities of the employed Canadian labor force. These surveys provide unique national-level data on the managerial levels, qualifications, sex of supervisor and divisions of paid and unpaid labor among male and female managers which could provide benchmarks for further international surveys. Women's representation in top-level jobs remains very restricted, and most women still manage only women. Greater employment experience and higher educational qualifications are now generally significant factors for promotion of women as well as men. But glass ceilings maintained by men and women's own primary responsibility for household work remain the major obstacles to equitable promotion. Women managers' increasing economic power remains contingent on facing up to these interrelated barriers.


DNA was extracted from human and animal bones recovered from archaeological sites and mitochondrial DNA sequences were amplified from the extracts using the polymerase chain reaction. Evidence is presented that the amplified sequences are authentic and do not represent contamination by extraneous DNA. The results show that significant amounts of genetic information can survive for long periods in bone, and have important implications for evolutionary genetics, anthropology and forensic science.


Dear Readers, "The ball is round, and a game lasts 90 minutes." (Sepp Herberger). And we know what to do. We have no choice. We throw everything forward. Every woman, every man. Even if we are acting defensively and time is running out. We go all in – we almost completely blow our cover. We know what to do: nearly anything – really anything. "The round thing has to go into the square thing." (Sepp Herberger). It's that simple. With this clarity, concentration and stormy composure, thousands of scientists, health and nursing professionals, doctors andmembers ofmany other healthcare professions are currently working – no fighting the battle against a much smaller opponent – a tiny one: the new coronavirus 2019-nCoV [1], which cannot even be stopped by the tight netting of a mouth and nose protector, let alone a football net. Faced with the current situation, it is simply unthinkable to write a medical text without making a reference to this pandemic. Too much suffering, too many exhausted helpers, too many overwhelming experiences. 375,498 confirmed cases and 16,362 deaths in 195 countries and territories have been recorded according to the latest WHO statistics (as of 25.03.2020; [https://experience. arcgis.com/experience/685d0ace521648f8a5beeeee 1b9125cd]. In Wuhan, people are cautiously hesitant to leave their shelters again, while in other places they are waiting in fear – with reports from Spain and Italy breathing down their necks – for the first offshoots of the great wave of sick and respirator-dependent people. We are all preparing ourselves – bracing ourselves for the unknown. We have one of the best healthcare systems. We are well educated. Without wanting to overtax the power of association: This issue, too, reflects part of a mosaic of many thousands of individual conceptual and scientific achievements which, taken together, will help us to overcome – and I am sure we will overcome – this current crisis. The scope of this issue ranges from interactive learning methods for improved knowledge acquisition in microscopic anatomy [2], the contribution of international mobility to medical professionalization [3] and the evaluation of interprofessional attitudes [4], to the illumination of the long-term evaluation of themedical didactic qualification within the framework of the Master of Medical Education (MME; [5]), the optimization of the evaluation of clinicalpractical trials [6], the strengthening of outpatient care through the curricular implementation of learning content [7], programs to strengthen rural care [8], and train-thetrainer programs for the qualification of continuing education officers in general practice [9]. It is precisely these didacticians, teachers, scientists and authors who are making their contribution so that we do not find ourselves powerless in the face of a crisis. Yes, they are. As if that were not enough, I am putting you through even more today. Because at the moment, in view of the many deaths caused by the corona crisis, all the stress on the helpers and the social insecurity in society, it is hard to name and believe: the corona crisis will be far eclipsed by another crisis: the climate crisis. The Lancet Countdown on health and climate change [10] has made this very clear: the health of society in future and the generations to come depends entirely on how we deal with climate change today. According to the latest study by the World Bank, 140 million climate refugees [11] will be added to the 70 million refugees currently in the world by 2050 – combined with enormous despair and suffering [12]. By the end of the current century, depending on the type of cereal, we will have seen harvests decline by up to 19% [13] and will be faced with the question of how to feed the 7.7 billion people currently


An indel refers to a single insertion or deletion, while an edit refers to either a single insertion, deletion or substitution. We investigate codes that combat either a single indel or a single edit and provide linear-time algorithms that encode binary messages into these codes of length n. Over the quaternary alphabet, we provide two linear-time encoders. One corrects a single edit with 2⌈log n⌉ + 2 redundant bits, while the other corrects a single indel with ⌈log n⌉ + 2 redundant bits. The latter encoder reduces the redundancy of the best known encoder of Tenengolts (1984) by at least four bits. Over the DNA alphabet, exactly half of the symbols of a GC-balanced word are either C or G. Via a modification of Knuth's balancing technique, we provide a linear-time map that translates binary messages into GC-balanced codewords and the resulting codebook is able to correct a single edit. The redundancy of our encoder is 3⌈log n⌉ + 2 bits and this is the first known construction of a GC-balanced code that corrects a single edit.


The aim of the study was to analyze the relationship between monocyte subpopulations and phenotype/ functions of monocyte-derived dendritic cells (DCs), as well as DC sensitivity to the tolerogenic effect of dexamethasone. Materials and methods. The study included 15 healthy donors. DCs were generated by cultivating enriched fractions of CD14 + monocytes with or without CD16 + cell depletion (CD16 − Mo-DCs or CD16 + Mo-DCs, re-spectively) in the presence of interferon alpha (IFN α ) and granulocyte-macrophage colony-stimulating factor (GM-CSF). Monocyte subpopulations were obtained by immunomagnetic negative selection. Results. CD16 + Mo-DCs were characterized by higher percentage of mature (CD83 + CD14 − ) and lower number of semi-mature (CD14 + CD83 + ) cells, but were similar to CD16 − Mo-DCs by HLA-DR and CD86 expression, involved in the presentation of antigens and activation of naive T-cells. and also to co-inhibitory/ tolerogenic molecules B7-H1 and TLR-2. CD16 + Mo-DCs displayed higher allostimulatory activity, which was positively correlated with CD86 expression ( r S = 0.69; p = 0.027) and negatively – with TLR-2 expression ( r S = − 0.72; p = 0.1). Allostimulatory activity of CD16 − Mo-DCs was positively correlated with the number of mature CD14 − CD83 + DCs and semi-mature CD14 + CD83 + DCs. Addition of dexamethasone (10 -6 M) into CD16 − Mo-DCs and CD16 + Mo-DCs cultures led to the delay of DC maturation, the decrease of CD86 and the increase of TLR-2 expression, as well as the increase of cells with co-inhibitory CD86 − B7-H1 + phenotype that was positively correlated with the reduction of DC allostimulatory activity. The decrease of CD86 + /TLR-2 + index in CD16 + Mo-DC population was due to the reduction of CD86 + DCs and in CD16 − Mo-DC population – to the increase of TLR-2 + cells. Dexamethasone possessed higher inhibitory effect on DC maturation in the CD16 + Mo-DC cultures. Conclusion. CD14 + monocytes, both contained and depleted by CD16 + cells, can differentiate into DCs when cultured with IFN α . The presence of CD16 + cells in whole blood monocyte pool is associated with generation of DCs showed a more mature phenotype and higher allostimulatory activity. Both CD16 − and CD16 + monocyte-derived DCs are sensitive to suppressive effect of dexamethasone. However, dexamethasone tolerogenic effect involves different mechanisms in CD16 − Mo-DCs and CD16 + Mo-DCs.


Introduction Increasingly, researchers are required to write Data Management Plans (DMPs) and to deliver the plan to their research funder or research institute. The Research Support and Advice working group of the Dutch National Coordination Point Research Data Management (LCRDM) was curious to learn about the process of reviewing DMPs. The working group aims to provide all those involved in reviewing DMPs with dos and don'ts and to get a rough idea of the effort of reviewing.


Objective This study explored ballroom dance as serious leisure and successful aging in a sample of community-dwelling older adults. Methods Qualitative procedures were used to explore stories of ballroom dance and successful aging. Results Participants described positive successful aging and active leisure engagement. Three themes emerged from thematic analyses: (a) Ballroom Dance as Serious Leisure: Its Dimensions; (b) Ballroom Dance: Its Link to Successful Aging; (c) The Affinity: We Love to Dance!. Conclusion The participants' ballroom dance revealed serious leisure characteristics in conjunction with their successful aging. They loved to dance, self-identified as ballroom dancers, and orchestrated their dance activities within its social world. Future research should examine the relation of successful aging to the social world of ballroom dance.


The porous hybrid carbon and carbon nitride composites (C/CN‐P123‐x) with higher adsorption capacity and improved photocatalytic activity for methylene blue (MB) degradation were obtained using partially formaldehyde‐modified dicyandiamide and amphiphilic block polymers (P123) as precursor and soft‐template, respectively. The structures of as‐prepared composites were analyzed by thermogravimetric analysis, X‐ray diffraction, elemental analysis, nitrogen adsorption–desorption, scanning electron microscopy, transmission electron microscopy, photoluminescence spectroscopy, and X‐ray photoelectron spectroscopy. The effect of carbon content on the structure of the composites and the catalytic activity for the photodegradation of MB were determined under visible light. The optimal carbon content is determined to be 27.17 wt % on the C/CN‐P123‐0.8 with MB photodegradation rate of 0.0115 min−1, which was 1.92 times higher than that of C/CN‐P123‐0. The remarkably increased photocatalytic performance arises from the synergistic effect of hybrid carbon and graphitic carbon nitride. Also, the possible degradation mechanism of C/CN‐P123‐0.8 for MB was proposed. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

In an open cycle traveling wave thermoacoustic engine, a mean flow of hot gas passing through the regenerator can replace the hot heat exchanger as the source of heat input to the engine. Previous work has shown that a substantial difference must exist between the temperature of the solid material at the hot face of the regenerator and the mean temperature of the hot gas flowing into the regenerator at this interface. Heat transfer across this finite temperature difference has the potential to be a large source of irreversibility in this type of engine. This work analyzes the entropy generation due to the joining conditions between the regenerator and the open duct, and relates it to a loss in the ability to generate acoustic energy in the engine. This analysis allows us to draw some pertinent analogies between the mean flow case and the more traditional case, where a hot heat exchanger provides the heat input to the engine. In addition, this study also investigates the gain or loss of acoustic energy flu...

Educational technology, related to technological and computational advances facilitates learning. In this sense, the use of serious game, games that have purposes and specific content, can be a strategy in health education of adults and children. This study aimed to identify the serious game developed and validated in health in Brazil, published in national journals. It is an integrative literature review conducted in the databases LILACS, SciELO and BDENF. The sample consisted of 23 studies. The results revealed that the publications in technological research applied to health educational games online is a field still growing expansion. Recognizing the needs of users is essential to plan and implement new technologies according to the specific demands.


We introduce <italic>Web Service Slicing,</italic> a technique that captures a functional subset of a <italic>large-scale web service</italic> using an <italic>interface slice</italic> captured as a <italic>WSDL slice</italic> (a subset of a service's WSDL). An interface (WSDL) slice provides access to an <italic>interoperable slice</italic>, which is a functional subset of the service's code. The technique uses <italic>intra-operational</italic> and <italic>inter-operational analysis</italic> to identify web service changes. With the aid of an <italic>associative code-test mapping,</italic> we leverage the identification of affected operations to reduce the cost of web-service regression testing by extracting a subset of the existing test cases. Used in conjunction with a web service slice, this subset reduces the cost of web-service regression testing by enabling the running of fewer tests. Furthermore, we exploit two approaches: <italic>Operationalized Regression Testing of Web Services</italic> (ORTWS) and <italic>Parameterized Regression Testing of Web Services</italic> (PRTWS). ORTWS effectively tests <italic>intra-operational changes</italic> at the WSDL and WS-code levels, while PRTWS tests <italic>inter-operational changes</italic> involving <italic>inter-operational dependencies</italic> due to <italic>primary parameters</italic>. Finally, we present results obtained using our prototype implementation, <italic>AWSCM</italic> (<italic>Automated Web Service Change Management</italic>), in two case-study experiments that serve to illustrate the reduction potential of the technique using eight real-world web services.


We aim to predict the number of COVID-19 infections per 1 million population in Indonesia. This is to help the Indonesia Government to decisively take exact measure in preventing and fighting the COVID-19 in Indonesia, as well as to predict the number of logistics and human resources required in fighting this dangerous disease.


This article examines the role of the gay leather community in the development of the home sex dungeon since the 1970s. The author maps points of contact between commercially produced equipment, publications containing advice on furnishing, and the approaches production of a domestic space that was documented by its owner. By tracing how style developed in tandem with collective making processes, the author reveals the centrality of collective making processes to the development of gay leather culture and identity in the United States. However, as the production of spaces for sexual fantasy have a limited space for expression in the home, the sex dungeon can also reveal tensions inherent in the construction of the leather identity.

RF and wireless applications stems from the view that, because of its flexibility, it can be exploited to overcome the limitations exhibited by integrated RF devices1 and, in doing so, enables circuits with new levels of performance not achievable otherwise. Thus, the ultimate goal in applying RF MEMS is to propagate the device-level benefits all the way up to the system level to attain unprecedented levels of system performance, as shown in Figure 1. In this section, early examples of circuits exploiting MEMS are presented.


Although much has been written about Frank Parsons, the founder of the vocational guidance movement, little is known about the 1st counseling staff of the Vocation Bureau. Lucinda Wyman Prince, Ralph Albertson, and Philip Davis each deserve recognition for their role in founding vocation guidance as well as their civic contributions. This article describes the roles and contribution of the profession's 1st counselors. Much has been written about Frank Parsons's role in the founding of Boston's Vocation Bureau. Written shortly before his death in 1908, a letter in the Yale archives highlighted Parsons's handing over legal power of attorney to Ralph Albertson (Parsons, 1908a). Something else is found in this piece of history conspicuously tucked into the upper, left corner of the handwritten note. Listed in the margin of the Vocation Bureau's letterhead, along with the executive committee and trustees, are the names of the first counseling staff of the Vocation Bureau and its three satellite offices. Mrs. John T Prince or Lucinda Wyman Prince, Albertson, and Philip Davis all carried the tide of "Associate Counsellor" (Parsons, 1908a, p. 1). Albertson was the most well known of the trio because of his close association with Parsons as a confidant and literary executor. Davis received brief mention from time to time, and Prince was but a mere footnote in counseling literature. Yet, Prince, Albertson, and Davis were each highly successful, well-respected individuals with their own significant contributions to vocational guidance as well as other movements. Whether through genius, luck, or a combination of both, Parsons enjoyed the good fortune of this vibrant and capable trio: the educator, the dreamer, and the immigrant. At the 100th anniversary of both the bureau's founding and its founder's passing, perhaps the field is now ready for a more in-depth look at the individuals who worked side by side with Parsons operationalizing a vision and cementing a legacy. Lucinda Wyman Prince: The Educator Prince was arguably the first female counselor, one of the three original "Associate Counsellors" listed for the Vocation Bureau (Zytowski, 2001). However, there was much more to Prince than her distinction of being involved with the Vocation Bureau. Like Parsons, Prince was a visionary and a most talented educator. Prince was born in 1862 in Waltham, Massachusetts. She was trained as a teacher at Framingham State Normal School, with further education at Wellesley College. She spent some time studying in Germany where she observed the continuation school model of education (Marquis, 1916; Norton, 1917). Prior to her association with the Women's Educational and Industrial Union (WEIU), she worked as a school administrator. In 1893, she lived in residence at Denison Settlement House, which was located in the South End of Boston, serving immigrant families (Denison House, 1913). Highly aware of social issues affecting women, Prince became an active member of the WEIU in Boston, a beacon of social justice, providing a variety of services to working women with limited resources. The staff offered legal consultation and aid, vocational guidance and placement, and a number of educational programs, the most popular of which was the Union School of Salesmanship founded and directed by Prince (Potter, 1998). While serving as a leader for a club of 50 young women at the WEIU, most of whom held low-paying jobs at department stores, Prince became interested in salesmanship (Norton, 1917). Lacking the appropriate training, the young women had little chance of advancing to better paying, more respectable positions. Prince decided to develop a training program on retail selling with the hope that it would rectify the situation. In 1905, she established a salesmanship training program through the WEIU (Gordon, 1999; Lynch, 1983; Norton, 1917; Riggle, 1998), without fully realizing the challenges awaiting her. …


four hours' cessation I judged further administration unneceseary. Still it seems remarkable in view of his reports that the patient, after the heroic doses given, responded throughout without suggestion to the calls of Nature, and was able so ,obviously to keep jealous watch, waking or gleeping, over the movements of his wife. The statement that " the full effect .of the drug is not manifest for at least twenty-four hours after the last dose " is well borne out. With regard to this method being " a new departure in the treatment of acute mania," I would refer to Clouston,2 when he says: "I have used the bromide alone in acute mania extensively and experimentally. In small doses it seems to bave no effect. In very large and -continuous doses, say a drachm every three hours, continued {or'many days, it will cause bromism and quiet the patient; but when its influence is over he becomes as bad as ever. I have'never seen any medicine where the maniacal excitemnent and the physiological brain torpor of the drug seemed -o visibly to fight for the mastery." It would appear from this that the same quantity of the drug per diem is more potent when given in larger doses at shorter intervals.


The effects of two types of on-pasture supplementation on slaughter characteristics, carcass traits and cut yield of purebred steers of the native Criollo Limonero dairy breed were studied. Thirty-six months old animals were randomly alloted to the following treatments during a 158-d fattening trial: T1 = a non-suplemented control group grazing Echinochloa polystachia grass; T2 = grazing plus 1 Kg/d/head of a concentrate to 11% CP, and T3 = grazing plus 1h/d of pruning an arboreal legume (Leucaena leucocephala). Analysis of variancecovariance by the least squares method indicated that none of the supplementation treatments (T2, T3) affected (P > 0.05) dressing percentage, carcass traits and cut yield. The only significant effect observed was the lesser proportion of white viscera (rumen and annexes) yielded in animals supplemented with Leucaena as compared to the control (7.98% vs. 7.07%). Other management and/or feeding strategies with high-energy diets need to be assessed to improve the carcass quality and cut yield performance of this tropically-adapted Bos taurus breed.


This letter argues that findings of a test on a national program to treat chronic tuberculosis (TB) patients with directly observed treatment (DOT) with second-line drug for 18 months give a definite message of hope for implementation of DOTS-plus in TB endemic countries with high prevalence of drug-resistant TB.


An alternate graphic representation of the Evans root locus plot, called gain plots, which exposes the relationship between the gain and the pole locations in polar coordinates, is presented. Gain plots portray the magnitude and angle on each closed-loop system eigenvalue in the complex plane as a function of gain. The gain plots highlight several important stability and performance features of the system. Inspection of the gain plots provides information about the closed-loop eigenvalue sensitivity to changes in gain. Gain plots provide a unified approach for single-input, single-output and multivariable systems where compensation dynamics are governed by a single scalar gain amplifying all plant inputs. An example demonstrates the utility of the gain plots for multivariable systems that possess complex conjugate root loci. The state space representation for this example is a linearized model of the vertical plane dynamics of an aircraft with three inputs, three outputs, and five state variables.<<ETX>>


Xinhua to Xupu's highway is located in the western mountain area.Some special problem often encountered during construction process,for example,the safety problems of pile foundation set in high and steep slope belongs to Liangjiang grand bridge.The stress and deformation of bridge pile foundation in high and steep slope is more complicated compared to normal pile set in ground.The current design method can't meet the needs of the practical engineering.This paper analyzed the stress and deformation of 19# pile foundation in Liangjiang grand bridge by using finite difference method considering the influence of slope load.The results show that the Horizontal displacement of the pile head did not meet the requirements of deformation considering the slope load and because of the large pile internal force,a slope protective reinforcement design must be carried out.


Il muro di Padova: un muro di solida paura - The Padua Wall: a Wall of Solid Fear, If there is a lucky relevance in the concept of liquid fear, it is the physical image of what, not having a solid content, slides over, trickles through chinks and floods any surface that comes across. If applied to a specific case, the concept materialises in its solid ambivalence. In the Padua case under examination, the municipality makes the choice, explosive from a communication perspective, to par8 tially isolate - with an iron fence, the so-called wall - an inhabited area, considered out of control because of the growing flow of regular and irregular immigrants, of crime episodes, of drug dealing, of acts of intolerance by some of the residents. The area will be evacuated due to a serious sanitary emergence, the residents of that compound will be transferred in smaller groups in other buildings in the city. The fear of residents of the neighbouring area to find drug dealers in their homes will fade away. The solidity of an extreme measure will stay, as well as having indicated a solution in front of a failure, that is what terrifies most people. Key words: local government, urban policies, security strategies.


In this paper, we focus on the design and analysis of channel access in vehicular ad hoc networks (VANETs) for event-driven multi-hop safety services. First, a novel channel access scheme that incorporates an application-level distance (timer)-based rebroadcast is designed to enhance the reliability and efficiency of safety message delivery. In the scheme, an effective new approach integrating transmitter-oriented repetitions, ESD bitmap, message sequence number, and modulo based waiting mini-slot is provided to overcome possible concurrent timer due among close nodes and possible message collisions in the conventional distance-based timer for selection of multi-hop forwarders. The reliability and performance of the proposed scheme are analyzed and compared with that of other broadcast schemes for VANET event-driven safety services on highways. The new analytic models account for the impact of the Nakagami fading channel with distance dependent path loss and vehicle mobility on the reliability and performance. Extensive simulations are conducted to verify the correctness of our proposed scheme and models under realistic network parameter settings.
