The increasing number of skin cancer cases worldwide and the adverse side effects of current treatments have led to the search for new anticancer agents. In this present work, the anticancer potential of the natural flavanone 1, extracted from Eysenhardtia platycarpa, and four flavanone derivatives 1a–d obtained by different reactions from 1 was investigated by an in silico study and through cytotoxicity assays in melanoma (M21), cervical cancer (HeLa) cell lines and in a non-tumor cell line (HEK-293). The free compounds and compounds loaded in biopolymeric nanoparticles (PLGA NPs 1, 1a–d) were assayed. A structure–activity study (SAR) was performed to establish the main physicochemical characteristics that most contribute to cytotoxicity. Finally, ex vivo permeation studies were performed to assess the suitability of the flavanones for topical administration. Results revealed that most of the studied flavanones and their respective PLGA NPs inhibited cell growth depending on the concentration; 1b should be highlighted. The descriptors of the energetic factor were those that played a more important role in cellular activity. PLGA NPs demonstrated their ability to penetrate (Qp of 17.84−118.29 µg) and be retained (Qr of 0.01−1.44 g/gskin/cm2) in the skin and to exert their action for longer. The results of the study suggest that flavanones could offer many opportunities as a future anticancer topical adjuvant treatment.


In this paper, we present classical molecular dynamics (MD) simulations of model polymer/CNT composites constructed by embedding a single wall (10,10) CNT into two different amorphous polymer matrices: poly(methyl methacrylate) and poly{(m-phenylene-vinylene)-co-[(2,5-dioctoxy-p-phenylene) vinylene]}, respectively, with different volume fractions. The simulation results support the idea that it is possible to use CNTs to mechanically reinforce an appropriate polymer matrix, especially in the longitudinal direction of the nanotube. The comparison of the simulation results with the macroscopic rule-of-mixtures for composite systems showed that for strong interfacial interactions, there can be large deviations of the results from the rule-of-mixtures. In order to verify this study, results obtained have been compared with those given by Elliott and Han (2007).


Transportation has been one of the major limitations to exploration of the Antarctic. Snow tractors, commonly used for short overland hauls, are far too small to handle adequate scientific eqLlipment and personnel and are limited in range. Icebreakers float too low in the water for use close to shore. Helicopters are not only expensive for their carrying ability, but in Antarctica they face the treacherous whiteout-the horizon completely disappears between snowy land and featureless, white sky, sometimes causing pilots to fly straight into the ground. One answer, a new research vessel called Hero, combines modern research facilities with a flavor of past centuries -including sails and a wooden hull. Early in 1963, the need for appropriate transportation, equipped with laboratories for research on the way, became obvious to U.S. scientists hunting a site for a U.S. research station on the Antarctic Peninsula. Fjords, channels and hundreds of tiny islands surround the peninsula, which stretches northward to about 600 miles from Cape Horn at the tip of South America. The vast finger of snow and ice has long been of interest to scientists, partly because of its varied, storm-tossed climate, in contrast to the dry air masses of the inner continent. Its major attraction, however, is its abundance of life. Low-pressure weather systems cause upwelling of the surrounding bottom waters, bringing with them a rich supply of silicates, nitrates and phosphates -a feast for marine life. Near the bottom of the ecological chain are the phytoplankton, particularly diatoms, which thrive so successfully around the peninsula that they often form a bloom on the surface and discolor many square miles of ice. Jellyfish, small crustaceans and other creatuLres graze on the plankton. On the continental shelf can be found everything from sponges to sea spiders and the Antarctic codfish (Notothenia). At least seven species of whales and six of seals are known to live in the area. On land some 70 species of moss have already been found. along with five times as many varieties of lichens. Primitive insects and birds abouind. The U.S. has been scientifically interested in the peninsula since some 140 years ago, when naturalist James Eights made a series of observations in the South Shetland Islands. Three major U.S. expeditions went there in the years 1946 through 1948. ImpetuLs for a permanent research station, however, did not come until the U.S. Antarctic research program expanded to include biology and other life sciences that had been largely ignored through the end of the International Geophysical Year in 1958. When the actual site survey got underway, just over four years later, the investigators spent two months looking over some 30 possible sites, finally settling on a 24-by-37-mile chuLnk of icy, mountainous wasteland called Anvers ;Island. Anvers was picked because it was about midway along the peninsula's length, and about as far south as a ship could get, even in the December-toApril summer season, without running into dangerous amounts of sea ice. The need for a special ship operating from the base was clear from the start. In 1964, Britain offered the U.S. the use of its "Base N," which had been deactivated since 1958, located at the island's ArthuLr Harbor. In the same year, the National Science Foundation awarded the contract for the ship's design. From their inception, ship and station were planned as a single facility. part of which was eqtuipped to go to sea. Last March, a permanent station near Base N was christened Palmer Station. for Nathaniel B. Palmer, who in 1820. at the age of 20, became the first American to sight the Antarctic continent. Eight days later, on the high tide. the unuLstual research vessel slid down the ways of the Harvey F. Gamage shipyard in SouLth Bristol, Me., after being christened the Hero in honor of Palmer's sloop of the same name. The 300-ton vessel draws only 12 feet 6 inches of water, compared to the 29-foot draft of a typical icebreaker. 'It can get in and arouLnd these islands in the Antarctic Peninstula, so that we have a platform for research," says marine biologist Dr. John H. Dearborn of the University of Maine's research center at Walpole, who went on the Hero's Arctic shakedown cruise. "It's sort of a cross between a large oceanographic ship and a shore party." Its 125-foot length wouLld dwarf the original Hero. buLt its most tintsLial featuLre, for a modern-day research ship. is its sails. A 760horsepower diesel provides the main power, buLt for steadying the ship during precise measurements, as well as for providing an emergency ptush if necessary, the dark green ketch-rigged trawler carries some 1,700 square feet of high-visibility orange nylons. Though not a fuLll-fledged icebreaker. the new Hero has been made as strong as possible for its pioneering role. which it will assume this month: the first ship to be based in Antarctica. Unlike ice-


In a great many societies which do not consume milk as a usual adult food, the ability to assimilate milk sugar (lactose) is rare or absent among adults (McCracken 1971; Kretchmer 1972). The ability to digest lactose is dependent upon the enzyme /3galactosidase (lactase), which is produced in the small intestine. Ferguson and Maxwell (1967) have suggested that lactase production in humans is controlled by a single gene having three alleles. Ransome-Kuti et al. (1975) have produced evidence which indicates that two alleles are involved. It is clear, however, that the trait is heritable. It has been demonstrated that the enzyme is not inducible in infants and children (McCracken 1971). Symptoms of nonabsorptive lactose intolerance are diarrhea, intestinal cramping, and gas production (Caplinger and Boellner 1968). The osmotic effect exerted by the unhydrolized disaccharide in the intestine is an important source of discomfort. Undigested lactose passes from the normally sterile small intestine to the large intestine, where coliform bacteria ferment it, producing carbon dioxide, intestinal pain, and flatulence. Bayless and Rosensweig (1966) found that the lactose equivalent of 1.655 liters of cow's milk was sufficient to produce distress symptoms within 2 h in most lactose-intolerant adults tested. Evidence from a number of human groups lacking lactase as adults, including the Thai (Keusch et al. 1969), Australian aborigines (Elliott et al. 1967), some Indians (Chandra et al. 1969), and the Baganda of Uganda (Cook 1967), indicates that lactase levels begin to fall shortly after birth and continue to decline until 3-5 yr of age, at which time lactase levels are so low as to make children intolerant o even very small amounts of milk. Bayless et al. (1971) showed that lactose tolerance falls below 40% of "normal" tolerance by the age of 1 yr in Australian aborigines, 18 mo in Bantus, and 18 mo and 5 yr in two groups of Thai children. The inability to digest milk as adults is not confined to humans; among others, rats, dogs, and pigs have difficulty indigesting it (McCracken 1971). The sea lion, whose milk contains no lactose, cannot digest lactose even in infancy (Kretchmer 1972). The hypothesis which we wish to present is that progressive lactase deficiency in young mammals is a mechanism which ensures weaning, regulates the time of weaning, and affects the rate of weaning. Trivers (1974) has predicted that the amount of parental investment, such as nursing, which an organism makes will depend ultimately upon the benefit/cost ratio of the investment, where benefit is measured in terms of the probability of survival of the offspring and cost is measured in terms of the ability of the parent to produce future offspring. The level of investment made will tend to be such that the inclusive fitnesses of


As a new coding standard,H264 achieves good performance,but that makes it more complicated.Storm is one of the high-performance stream processors aiming at media application and signal processing,and it has a good prospect in media processing.In order to match the requirements of the computing performance of H.264,this paper presents a stream implementation of transform encoding in H.264(1080P) on the Storm-SP16 G160 stream processor.Combining different features of data-flow with a specific process of streaming,the stream technologies are explicated in detail,such as choosing the parallel particles,organization of data flow,and standardization.Experimental results show that stream implementation achieves high performance,and it satisfies the requirements of real-time encoding by accelerating the whole program according to this encoding efficiency.This implementation not only provides a reference for streaming other applications,but also presents a new way to accelerate programs.


Among the cultivated mushrooms of Tricholomataceae, Enokitake (Flammulinavelutipes), Hatakeshimeji (Lyophyllum decastes) and Nioushimeji (Tricholoma giganteurn), the proximate compositions, minerals, vitamins, dietary fiber, polysaccharides, fatty acids, and ergosterol contents were analyzed.Mushrooms are considered to be a good source of vitamin D2; therefore the determinations of vitamin D2 and studies of the effects of solar irradiation on the amounts of vitamin D2 and the quality of the mushrooms were conducted. The results were as follows.The proximate compositions, minerals and dietary fiber of these mushrooms closely agreed with previous reports. However, the vitamin B1 and B2 contents were slightly lower. The result of the vitamin D2 analysis showed that fresh mushrooms were found not to contain vitamin D2that differed from the Standard Table of Food Composition in Japan-VITAMIND-and the Standard Table of Food Composition in Japan, Fifth Revised Edition-shinkishokuhinhen-. However a remarkable production of vitamin D2 was observed due to solar radiation. The maximum values of vitamin D2 were observed in mushrooms irradiated for 1hour. This amount of solar radiation had no bad effects on the mushroom's quality.These mushrooms contained high levels of alkali acid-soluble polysaccharides, followed by formic acid-soluble polysaccharides and then hot alkali-soluble polysaccharides. The alkali-soluble acid-insoluble polysaccharides and acetic acid-solublepolysaccharides were found at low levels.Prosky modification I showed the lowest value followed by the chitin corrected method. Prosky modification II resulted in the highest values. These three methods gave significantly different values.In Enokitake, the contents of the linolenic and linoleic acids were specifically high. Hatakeshimeji and Nioushimeji contained high levels of linoleic and palmitic acids. The ergosterol contents were 216, 124 and 258mg/100g dry matter in Enokitake, Hatakeshimeji and Nioushimeji respectively.

Introduction: Latex hypersensitivity is one of the problems in healthcare workers. This problem affects the productivity of the workers due to the hypersensitivity symptoms. In Dental Polyclinic USIM, there have been complaints by dental personnel regarding the usage of latex glove. However, there was no data that have been documented. Aim: The aim of this study is to determine the prevalence of self-reported latex glove hypersensitivity among dental personnel in Dental Polyclinic of UniversitiSains Islam Malaysia. Methodology: A cross-sectional study was conducted using purposive non-probability sampling technique. 196 dental personnel in Dental Polyclinic USIM who used natural latex gloves in their work were selected. Questionnaire on respondent's information on latex glove hypersensitivity was sent by email to the respondents and data collection was done from August to September 2015. Nevertheless, only 91% response was obtained. Result: From 175 returned questionnaires, 55 (31.4%) respondents showed to have latex hypersensitivity symptoms. The most type of hypersensitivity symptoms was irritant contact dermatitis in 35 (20.1%) respondents, followed by Type IV response with delayed hypersensitivity in 14 (8.05%) respondents and immediate hypersensitivity Type I reaction in 6 (3.4%) respondents. Data analysis was done using Chi-Square test and there was a significant association between the latex allergy and the hours of exposure (p <0.05). Conclusion: Approximately one third (31.5%) of the dental personnel in Dental Polyclinic USIM has latex glove hypersensitivity through this questionnaire based study. Further study and further medical assessments need to be done to confirm the latex hypersensitivity among dental personnel, followed by specific measures in order to manage the hypersensitivity symptoms in clinical setting.

ABSTRACT:Despite hopes for a more equitable cinematic marketplace after the 1948 Paramount decision, the studios quickly developed new methods of dominating exhibition. One technique, the prerelease engagement, created an unofficial first run at higher prices before a film's official release. The Department of Justice's disinterested response to exhibitor complaints demonstrated that it was no longer interested in policing the industry. Using the trade press and congressional testimony, this essay traces the history of the prerelease and exhibitors' unsuccessful attempts to block it—an early example of the decline of the Paramount decrees as a means to counter studio dominance.


We reviewed with interest the letter by Thévenot and colleagues1 and we appreciate their comments regarding the novelty of the study findings and the need for additional data to further the knowledge about Cirrhotic Cardiomyopathy (CCM). In response to their inquiry, the echocardiographic studies, in our study, were obtained for liver transplant (LT) evaluation and the median time between those studies and LT was 107 days2 .


Field studies were conducted with the synthetic sex pheromone of southwestern corn borer (SWCB), Diatraea grandiosella (Dyar), to determine effect of type, height, and location of traps; pheromone concentration; and age of pheromone lure on number of captured SWCB males. Over a 4-night period, 13-, 19-, and 24-fold more males were captured in Heliothis Scentry traps than in Covered Funnel, Pherocon 1C, or Pherocon II traps, respectively. Male capture was not significantly different in traps ranging from 0.5 to 3.0 m in height or between traps placed at field border versus within the field. Field aging of pheromone-treated septa significantly influenced male capture. Attractiveness decreased as time of field exposure increased. Male capture increased as the concentration of synthetic pheromone increased. At least 1,000 μg of pheromone per septum was required for male capture to equal that of two virgin females.


The proliferation of regional organisations and more importantly the phenomenal exploits of the European Union (EU) have not only lent credence to the developmental feature of regional integration, but also an obsession with the traditional methods of assessing regional integration. Because the traditional methods of assessment relate to, and are primarily based on the objectives, goals and time frames that have been agreed upon by member states, there is a tendency to underestimate or completely ignore other measures capable of impacting positively on the pace of the integration process. This article examines the possibility of adopting a syncretic method of assessment, which is not limited to the traditional elements, but also includes non-traditional factors such as civil society involvement, technology, democratisation and skills development.


Barth's concept about sodium ingress into metamorphic rocks directly from the buried seawater sediments is considered in the paper. This concept solves the problem of sodium balance according to the Vernadskiy studies of geochemical cycles. Basing on this concept, sodium geochemistry in auriferous terrigenous complexes in different regions of Russia and other CIS countries is analyzed. It has been demonstrated that the sodium enrichment in terrigenous rocks occurs not only during the metamorphism process but also in formation of sedimentary rocks under the conditions of avalanche sedimentation and fast sediments immersion in the zone of catagenesis. The sodium is fixed in albite under thermodynamic conditions of catagenesis. Chloride is not finding its own mineral phase and transports gold from the mineral phase to the exfiltration silicate waters, because it has the high activity with respect to gold. Metallogenic result of this process is the formation of auriferous quartz veins and stringer zones in drain sandstone beds. Metallogenic specialization of normal potassic terrigenous sequences is determined by different factors displayed during the processes of sediment genesis and diagenesis or the future processes of metamorphism and (or) intrusive


Alginate,as a natural polysaccharide,has been used widely in food because of its functional characterstics. The calcium was mainly used in prodaction practice to prepare hydrogel,network structure of the gel-forming can improve characteristics of food. Its formation is affected by the concentration of sodium alginate,calcium ion binding concentration,temperature,pH conditions and other factors. Application of alginate gel receives much attention in the food industry,especially in microencapsulation,edible film,texture improvement and other aspects.


In recent years,the typology in the field of organization and human resources management( HRM) has achieved abundant accomplishment. But most of the theory- based HRM researches are relatively independent,and lack of the unified analysis and integration. This paper attempts to introduce typology to explore their consequence,and tries to establish a typology research compendium of HRM. It helps to recognize the effect and determinant of HRM roundly,and then establish the logic of classification based on the theory in order to guide and develop company's HRM practice.

Objective To verify the impact of varicocele on semen quality,sperm DNA intergrity and in vitro fertilization.Methods The sperm chromatin dispersion test was employed to detect the sperm DNA fragmentation in 103 infertile men with varicocele and 37 healthy fertile male.At the same time,the classical semen parameters including sperm concentration,progressive motility and sperm morphology were evaluated.Furthermore,outcome of in vitro fertilization in men with varicocele were evaluated.Results Men with varicocele had lower ejaculate volume,sperm concentration,progressive motility,morphology,and higher percentage of cells with DNA fragmentation than those in the control group.Compared with our homochronous total data,men with varicocele had lower fertilization rate and lower cleavage rate,but no signinficant difference in the biochemical pregnancy rate.Conclusion Varicocele could increase DNA fragmentation,and decrease the classical semen parameters,fertilization rate,cleavage rate of in vitro fertilization.


An electron plasma wave driven by optical mixing of two oppositely propagating microwaves is experimentally studied. The wave amplitude is resonantly enhanced when the difference in frequency between two incident electomagnetic waves equals the electron plasma frequency. The absolute amplitude and the growth time of the excited waves are found to be 0.8% and 150 nsec ( f p t =50, f p =340 MHz), respectively, at the incident microwave power of 40 kW. The wave amplitude obtained experimentally is in good agreement with that expected from the optical mixing theory with the damping term. The dominant damping term is ascribed to the Landau damping of high-energy electrons in the background plasma.


While genetic alterations in head and neck cancer have long been documented, the appreciation of epigenetic changes is more recent. Epigenetics of head and neck cancer becomes an area of emerging research direction due to a growing understanding of specific epigenetic pathways and rapid development of detection technologies. Epigenetic changes alter expression of tumor suppressor genes without changes in DNA sequence. Epigenetic mechanisms such as DNA methylation, histone modification and alteration in genomic imprinting have been shown to silence key genes involved in cell proliferation, differentiation and genome integrity, and clearly have a central role in head and neck cancer. The pattern of hypermethylation in any individual tumor can now be accurately determined, which may find application in molecular staging. The study of epigenetic changes should provide a global view of gene profile in head and neck cancer, and epigenetic markers could be used for early detection, prognosis, and therapy of cancer patients.

Guided oral reading has been shown to have positive pedagogical value; our Reading Companion provides a shared reading experience in which students read on-screen books aloud guided by the Companion, which offers scaffolded modeling of expert skill and feedback based on speech recognition. A student model is maintained for each student, which tracks student performance and decoding knowledge in terms of rules and word features. Decoding rules (or, more accurately, heuristics) involve mapping sequences and patterns of letters and letter categories to particular sounds. An example letter sequence heuristic makes "ph" sound like /f/; an example letter category pattern informs us that the pattern VCe at the end of a syllable usually makes the V have its long sound and makes the final "e" silent. An example word feature might be the fact that a word contains a specific consonant blend. We describe how the tutor maps spoken words to rules and word features (collectively referred to as linguistic facts), and how information about these data are maintained in the student model. The Reading Companion includes a sophisticated post hoc reporting facility, which provides a view into the student model, allowing teachers to gain insights into students' strengths and weaknesses, and facilitating targeted individualized interventions. The Reading Companion is Web-based and accessible via an ordinary browser.


During the 38th Annual Convention in New Orleans, Past-President Gerald R. Patterson graciously accepted the Parenting and Families SIG's Trailblazer Award, which is offered to individuals who have caused us to rethink important aspects of research and clinical work with children and families. Following a moving introduction by Dr. Marion Forgatch, Dr. Patterson shared his vision of "The Next Generation of PMTO Models," and in so doing, conjured the essence of the award, challenging us to rethink conventional wisdom about parent training models. The address also inspired, pointing the way toward potentially more effective strategies for working with families and putting healthy parenting and our efforts to promote it into context. We regretted that mention of Dr. Patterson's address was not able to be included in the regular convention program. So for the many more of you who might have attended but could not, Dr. Patterson's edited address appears below. — T H E E D I T O R

Details on applying Acoustography to inspect complex shaped parts will be provided. Future work in the area of Acoustography will also be presented.


A new approach to switching between states in reflective cholesteric liquid crystal displays is demonstrated that relies on the dispersion in the cholesteric material's dielectric properties due to flexoelectricity. Flexoelectric polarisation allows the device to be switched into a weakly scattering focal-conic state at low frequencies, while at higher frequencies the device is driven into the reflective Grandjean state. The non-conventional dual-frequency effect allows driving between states in both directions. The cross-over frequency can be as low as 300 Hz, orders of magnitude smaller than other dual-frequency effects. Devices of various reflective colours are demonstrated and have favourable contrast ratios, viewing angles, and switching behaviours at room temperature. The technique potentially affords a greater flexibility in surface alignment conditions, driving schemes, material parameters, and use of polymer networks in cholesteric devices than other switching methods.


The Indiana University 200 MeV Isochronous Cyclotron is a separated sector (N = 4) machine whose design goals include the acceleration of both protons and heavy ions over a variable energy range up to a maximum energy of approximately 220 Z2/A MeV. The large range in energy and particle mass requires that the radial profile of the magnetic fields be adjustable to match the relativistic mass increase of the accelerated particle. For the acceleration of protons to 200 MeV for example, an increase in the field from injection to extraction radius of about 22% is needed, whereas for heavier ions the field profile must rise approximately 2%.

Judging imaging quality is an important part of the maintenance of visual intelligent monitoring systems for electrical power scenes. However, accurate and efficient identification of possible abnormalities in imaging quality remains challenging. This paper proposes a novel multi-region two-stream deep architecture to improve judging abnormalities. The proposed architecture incorporates two-stream scheme and multi-region strategy to identify relevant information and explore hidden details. More specifically, in addition to color and intensity in the original images, the two-stream scheme uses high-frequency structure information from gradient images to enhance its performance. The multi-region strategy employs spatial pyramid random cropping and region fusion to handle locally non-uniform changes among categories: spatial pyramid random cropping characterizes images at different spatial pyramid levels, while region fusion focuses attention on cropped regions relevant to quality perception by using adaptive learning weights in a fully connected layer. In this way, the proposed strategy guides the framework to adequately and adaptively explore the discriminative regions hidden in the input images, and provides an end-to-end learning procedure. Experimental results demonstrate its strong performance for judging abnormalities, and the proposed method can be easily extended to the entire surveillance system.


Abstract The austenitic nickel-chromium based super alloy Inconel 718 is considered a difficult material to machine due to a combination of nickel, iron and cobalt. The material exhibits mechanical strength and resistance to surface degradation under extreme pressure and heat. It employed widely in aerospace, jet engines, gas turbine etc. This research work focuses on the optimization of cutting variables for each performance measure obtained by employing grey-Taguchi techniques. The orthogonal array, grey relation analysis and analysis of variance are employed to study the performance characteristics in turning Inconel 718 using a carbide cutting tool insert. Further, a simulation model based on an finite element approach is proposed using DEFORM-3D software for the prediction of tool wear through Usui's tool wear model. The study highlights the optimum cutting conditions and a favorable range of the machining variable values. Finite element method results show that predicted tool wear values according to DEFORM-3D produce a useful and adequate level of accuracy.


This study aims to determine (1) changes in land cover in the Mount Padang Region in 1996, 2006 and 2016, (2) changes in carbon stocks as a result of changes in land cover in the Mount Padang Region of Padang City.

REFERENCES: Reference Report: There are Places where the Author Rakesh Bharti Need to Cite a Reference, but Have Not Frustration is a human emotion that occurs in situations where one's goals remain unreachable indefinitely. Frustrating situations occur recurrently throughout the life. This study aimed to investigate the significant difference between scheduled caste/ scheduled tribe and upper caste students on mode of frustration. India's caste system is perhaps the world's oldest surviving social hierarchy. Caste encompasses a complex ordering of social groups on the basis of ritual purity. A person is considered a member of the caste into which he or she is born and remains within that caste until death, although the particular ranking of that caste may vary among regions and over time. There is no denial over the fact that education is an important instrument for all round development of society. RESEARCH DESIGN The study employs descriptive survey research design to carry out the investigation. In this study the investigator tries to find out significant difference between scheduled caste/ scheduled tribe and upper caste students on mode of frustration. SAMPLE Simple random sampling technique was used in the selection of the sample of present study. The present study was conducted on 345 students including 189 boys (upper caste=124 and SC/ST=65) and 156 girls (upper caste=114 and SC/ST=42) selected from different Higher Secondary Schools of Jammu Province. Table-1 clearly shows that significant difference exists between scheduled caste/scheduled tribe and upper caste students on frustration dimensionsObstacle-Dominance (O-D), Ego-Defense(E-D), Need-Persistence(N-P), Extra-Aggression(E-A), Intra-Aggression(I-A), Imaggression (M-A) and Group Conformity Rating (GCR). Frustration is devastation for students. It can hinder their successful life even ruin everything if not handled properly. Frustration usually occurs when one's intended personal goals and dreams are not met. Moreover, there are many feelings of frustration that had observed during frustration among students. Enduring depressed mood, crying spells, loss of interest or pleasure, decrease in aptitude level, feeling fatigue and feeling of anger or vengeance are dominant feelings among students during frustration. ?Carroll, H.A.

The use of case studies to teach materials science undergraduates is an exciting and interesting educational approach. As well as helping learners to connect theory and practice, the case method is also useful for creating an active learning environment, developing key skills and catering for a range of different learning styles. This paper explores the case-based approach and gives details of how they have been integrated into a number of degrees in the Metallurgy and Materials Department at the University of Birmingham. The evaluation of the case studies is also discussed along with the consequent actions and development.


We reformulate interval analysis so that it can he applied to any monotone data-flow problem, including the nonfast problems of flow-insensitive interprocedural analysis. We then develop an incremental interval analysis technique that can be applied to the same class of problems. When applied to flow-insensitive interprocedural data-flow problems, the resulting algorithms are simple, practical, and efficient. With a single update, the incremental algorithm can accommodate any sequence of program changes that does not alter the structure of the program call graph. It can also accommodate a large class of structural changes. For alias analysis, we develop an incremental algorithm that obtains the exact solution as computed by an exhaustive algorithm. Finally, we develop a transitive closure algorithm that is particularly well suited to the very sparse matrices associated with the problems we address.


4-n-propoxy benzoic acid (A) was prepared by alkylation of 4-hydroxy benzoic acid with n-propyl bromide, on the basis of Williamson synthesis of ethers  in the presence of Potassium hydroxide using absolute ethanol- water (10:1) . Compound (A) was in turn converted to 2-amino 5- (4-n -propoxyphenyl )- [1,3,4]-thiadiazole (A 1 ) by the reaction with thiosemicarbazide in the presence of phosphorus oxychloride. Some new aromatic Schiff bases ( substituted benzylidene ) - [5- (4-n-propoxy-phenyl)-[1, 3, 4]-thiadiazol- 2- yl]-amine (B (1 – 8 ) ) were synthesized by condensation of equimolar amounts of compound ( A 1 ) and substituted benzaldehydes in absolute ethanol using glacial acetic acid as a catalyst. The structure of products were confirmed by (I.R, 1 H-NMR, 13 C- NMR and DEPT - 135) spectra .

Resting heart rate (RHR) and heart rate variability (HRV) reflect the autonomic control of cardiac chronotropic activity, and they associate with cardiovascular fitness, acute and chronic health status, and mental stress. Relatively low RHR and relatively high HRV are generally seen as marks of better health, performance, and recovery levels. Nevertheless, the values are highly individual and comparison between individuals is not straightforward. On the other hand, evolution of wearable devices has made it possible to follow the course of individual RHR and HRV as long-term time series, which in turn enables observation of how behavioral, societal and seasonal factors affect RHR and HRV at individual and population scale. In this article, data measured by the Oura ring is used to study how alcohol and training affect these values, and moreover, how societal and seasonal factors affect us as a population.

Because the present invention can increase the resistance of monocots such to various stresses, it can contribute significantly to the production and improvement of the quality of valuable crops.


This paper aims to introduce the process used to create a "Parallel Learners' Corpus of Spanish and English" (CPATEI) by integrating the theories and techniques of Corpus Linguistics, and to investigate the conjunctions used by the Spanish learners in Taiwan. The collected data in CPATEI are contributed by learners of Spanish from two universities in Taiwan, including Spanish compositions and their corresponding English translations written by two different levels of Spanish learners. Besides, we have collected texts revised by native speakers and POS-tagged. Based on the collected data, we will examine the tendency of learners' overuse, underuse and misuse of the conjunctions. At the same time, we will discuss the possible factors leading to incorrect usage of conjunctions. The results demonstrate that the frequency of conjunctions used by the learners in their Spanish compositions and English translations are lower than that of the Spanish and English native speakers in their corrections. Among the types of errors of conjunctions, underuse of the copulative and additive conjunctions and overuse of the adversative and cause-consecutive conjunctions are the two types of errors that have been noted in the writing of the Taiwanese learners. Furthermore, there are no relationships found between the wrong use of the Spanish conjunctions and their language level as well as the second language as English and the third language as Spanish. Finally, we hope the result of this research will bring benefits to the curriculum designs for the teaching of Spanish conjunctions.

The sheer scale of packaging materials used in dermatological cosmeceutical products in the United Kingdom and internationally has not yet been systemically examined. As responsible global citizens, we should reduce, reuse and recycle the everyday materials used to help us live a more sustainable lifestyle.


A previous article in this series, Descartes as geophysicist (TLE, August 1985) prompted a letter from Sven Treitel commenting that Descartes indeed had a role in the discovery of the law of refraction (now generally credited to Willebrord Snell) but Descartes' work had one major flaw — it essentially put things exactly backwards!


Large cardamom (Amomum subulatum Roxb.) belongs to family Zingibereaceae and order Scitaminae is the most suitable cash crop for the hilly terrain of the state of Sikkim. Likewise a large section of farmers in North Sikkim and most parts of Sikkim are engaged in large cardamom cultivation. For years cardamom has been the single most crucial cash crop to these stakeholders. However recent times have shown a steep decline in the land holdings, as well as productivity under large cardamom. Although not evident apparently, it has drastically affected the livelihood of a large section of the rural population. In Dzongu, North Sikkim where Indian cardamom Research institute in collaboration with ICAR has launched the National Agricultural Innovation Project (NAIP) component -III, from 2007. The project has been able to experience and identify certain aspects which need closer attention and evaluation, if large cardamom as a cash crop or simply as a horticultural crop is to be cultivated in the State of Sikkim towards sustainable source of livelihood. The NAIP initiated, with the objective of development of improved farming systems in large cardamom plantation in Dzongu, North Sikkim.

This paper describes two ultra-wideband synthetic radars (SAR) currently being developed. One, the Foliage Penetration Advanced Technology Demonstration, will be installed on an Army C-12 and eventually the Global Hawk Unmanned Aerial Vehicle. It is designed to detect stationary military vehicles, which are camouflaged or hidden in forests and tree-lines. It employs a VHF SAR for screening and a UHF SAR for rejection of false-alarms. The second is an interferometric SAR for topographic terrain mapping. It operates on a business jet simultaneously with an X-band SAR. Together the two obtain high-quality imagery and terrain height of the ground even under foliage. The paper describes the phenomenology of foliage penetration, ultra-wideband SAR, and the different design issues associated with target detection and terrain mapping.


Court closures in response to the COVID-19 pandemic have led some to consider the possibilities of virtual jury trials, with at least one state court already conducting a virtual trial in a civil case. The Supreme Court's recent decision in Ramos v. Louisiana, in which the Court held that jury verdicts must be unanimous, sheds light on the constitutionality of virtual trials in criminal cases. But the answer that Ramos suggests—that virtual criminal trials are unconstitutional—is difficult to square with the answer offered by constitutional theory. Though the author of the Court's opinion in Ramos, Justice Neil Gorsuch, is ostensibly an originalist, originalist theory (reflected in the scholarship of, among others, Professors Larry Solum, Randy Barnett, and Jack Balkin) would seem to allow for virtual trials because that inquiry falls in the Constitution's "construction zone." The Constitution says nothing about whether jury trials must be in-person, affording legal actors greater (although not unlimited) latitude to adjust jury practices to take account of current circumstances. This essay compares the Ramos Court's analysis to that of prominent originalists to preliminarily address whether virtual jury trials are constitutional. Additionally, through that comparison, this essay demonstrates the extent to which originalist theory has yet to succeed in shaping Supreme Court decision-making.


A detailed investigation of "ɡewai"( 格外) and "fenwai"( 分外) were taken respectively in syntactic feature,semantic and pragmatic functions and the origin as well as the development of these two adverbs. And these two adverbs differ in modifying verbs,repetition,the ability of modifying adjective combined with "zhi"( 之) and so on. In addition,differences in semantic orientation,stylistic coloring and usage frequency are observed. Historical reasons attributing to these differences are discussed in the end of this paper.


The concept of translation norm has occupied a prominent place in Translation Studies as a terminological challenge for scholars and the reflection of their research fields. The emergence and internalisation of norms is a natural consequence of the socialisation process since norms can be also used as evaluation criteria for certain social (permissible and acceptable) behaviours. However, the operation of norms in translation is hard to be observed: the objects of direct observation are products of the translation process and results of norm-governed translator behaviour. If we attempt at analyzing norms in terms of criteria accuracy and usefulness in translation, then we also have to consider the need for them to be used by translators and, what follows, the type of translator who applies these norms. A question might be asked whether norms hinder or rather facilitate the process – a potential answer suggests the dependence of norm application on the translator's experience and knowledge accrued as factors central for successful performance.


The preparation method of 2-amino-2-(2-(4-octylphenyl)ethyl)-1,3-propylene glycol hydrochloride includes the following steps: adopting capryl halogen and benzene and making them react under the action of catalyst to obtain capryl benzene, utilizing reduction reaction to obtain octylbenzene, then making the latter and halogenated acetyl halogen or halogenated acetic anhydride react under the action of catalyst to obtain 4-halogenated acetyl octylbenzene, and making it undergo the process of reduction reaction to obtain 4(2-halogenated ethyl) octylbenzene; making the latter and malonate produced condensation reaction under the alkaline condition, and making said product undergo the processes of nitrosation, reduction, cracking and neutralizing so as to obtain the invented product.


We calculate the photoionization cross section of a ${\mathrm{BaO}}_{2}$ molecule in the region of the Ba 4d-f giant dipole resonance, i.e., 90--150 eV, taking into account both many-electron screening and molecular, multiple scattering effects. The potential of the oxygen ligand atoms is expanded in spherical harmonics around the central Ba atom and screening is treated within the time-dependent local-density approximation. The cross section shows prominent modulations and structure due to final-state molecular resonance effects, in good qualitative agreement with experimental results on solids.


The utility model discloses an external wall thermal-insulating board with Al-Mg-Mn alloy faces. The external wall thermal-insulating board comprises an inner protecting board and an outer protecting board, wherein the inner protecting board and the outer protecting board both play the roles of bearing and supporting and arranged oppositely; and a central core material made of fireproofing material is arranged between the inner protecting board and the outer protecting board, and the two ends of the outer protecting board respectively are a first S-shaped part and a second S-shaped part which can be matched with the first S-shaped part in shape. The external wall thermal-insulating board is characterized in that the two sides of the central core material respectively are a left sealing edge and a right sealing edge which are respectively connected to the inner protecting board and the outer protecting board; and the inner protecting board and the outer protecting board are both made of Al-Mg-Mn (aluminum-manganese-magnesium) alloy material. The external wall thermal-insulating board with Al-Mg-Mn alloy faces avoids condensation and has the advantages of high strength, low possibility of distortion, good flatness and aesthetic appearance; through the adoption of the Al-Mg-Mn alloy material, the external wall thermal-insulating board has the characteristics of light weight and long service life; and the utility model further has the advantages of high strength, strong impact resistance, high capability of resisting negative wind pressure and high fireproofing grade.

The simulation of the proposed antenna is done by Ansoft HFSS v 13 (high frequency structure simulator).


Introduction.-This paper is in continuation of a previous paper t under nearly the same title. The notation given there is used in this paper with the exception that u, v are here used instead of ,u, v. We are concerned with a doubly infinite system of given curves: (1) f3(Au V) + Af2(u, v) + Bfi(u, v)=O, of which the differential equation is t (2) a du3 + a4 dv3 + a2 dU2 dv + a3du dv2 + a5 (du d2v dvd2u) = 0.


In November 2002, the Prestige, an obsolete oil tanker, sank and spilled her cargo offshore Galicia (in the northwest of the Iberian Peninsula). This accident originated a social experiment, unwanted but valuable to understand how the catastrophic experience of the "manufactured risks" is socially represented. The present article analyzes the response of the regional education system to the catastrophe from two viewpoints: a) of its comprehension in the context of the critical and proactive social response to the official intent of representing a "non-catastrophe", and b) of the role of Environmental Education (EE) as a pedagogical praxis whose political dimension is revealed as indispensable. The thesis we shall defend is that the political nature of EE, many times just implicit and others explicitly denied, is recognized here as the fundamental axis in the response of the education system and of other education agents. In this sense, the catastrophe has not been just ecological but also, and foremost, social and political by questioning the economic globalization – its profound cause – and by putting in evidence the vulnerability of the administrations, incapable of preventing or mitigating its impact on the environment and on the human communities. In this scenario, EE contributes to the reflection about the origin of the catastrophe as an unforeseen consequence of the "advanced modernity", in conformity with the analysis by Ulrich Beck of the "risk society", and of the politizing potential of the successive catastrophes – the tip of the iceberg – in which the new social ethos is manifested and constructed.


If the electroweak symmetry-breaking sector becomes strong at energies above 1 TeV as a result of the absence of a low-mass Higgs boson, and if only the minimal complement of Higgs particles is present, one expects an isovector spin-1 meson of mass 2 TeV/${c}^{2}$, and width 400 GeV, decaying mostly to ${W}^{\ifmmode\pm\else\textpm\fi{}}$Z or ${W}^{+}$${W}^{\mathrm{\ensuremath{-}}}$, on very general grounds. Thus, if longitudinal W's and Z's and Higgs bosons are actually fermion-antifermion composites, one must study systems other than this heavy vector meson to learn the nature of the constituents. The role in such studies played by the corresponding spin-1 isoscalar meson, also expected to have a mass of \ensuremath{\approxeq}2 TeV/${c}^{2}$, is examined, and compared with the corresponding role played by the \ensuremath{\omega} in hadron physics.


A 78-year-old man, known to have hypertension, presented to the emergency department with stabbing, transfixing chest pain, evolving over the past 2 days. On examination, blood pressure was elevated at 171/96 mm Hg and there was a holosystolic murmur on cardiac auscultation. The electrocardiogram showed ST-segment elevation in aVR combined with ST-segment depression of >1 mm on infero-lateral leads V4–V6 and DI, DII and aVL suggestive of left main coronary artery stenosis (fig. 1) and ultra-sensitive troponin was elevated at 876 ng/l (reference range <18 ng/l). The patient was diagnosed with an acute coronary syndrome and transferred for urgent angiography. Coronary angiography confirmed a critical stenosis of the left main coronary artery (fig. 2 – panel A) but when the interventional cardiologist tried to reposition the catheter in the left main coronary artery for stenting, an injection of contrast revealed an adjacent structure. At this point the operator proceeded to aortography, which showed this structure to be an aneurysm of the ascending aorta compressing the left main coronary artery (fig. 2 – panel B) and responsible for the identified stenosis. The patient was taken immediately into surgery. Sternotomy exposed a covered rupture of the aorta compressing the left main coronary artery, as well as a haemopericardium.


O ver the last 25 years or so, rigid polyurethane and polyisocyanurate foams have proven themselves to be two of the most versatile, efficient, and cost effective thermal insulation materials available. These insulation materials have been used successfully in applications ranging from roofing to the external fuel tank of the space shuttle. One application where rigid polyurethane and polyisocyanurate foams have not been extensively used, however, is in the concrete block and masonry wall cavity insulation markets, where materials such as expanded perlite, expanded vermiculite, urea-formaldehyde foam, and polystyrene foam inserts have traditionally dominated. Although the reason for this is not immediately clear, a closer look at the heat transfer mechanism of a concrete block wall will show that the high thermal efficiency (low k-factor) and the low cost vs. R-value advantage, which rigid polyurethane and polyisocyanurate foams enjoy in most applications, do not exist, to as great an extent, in a concrete block wall insulation application and favor the use of a lower cost, albeit less efficient, thermal insulation. A new foam insulation material, tradenamed POLYCTM, has been developed by The Upjohn Company which does provide the proper balance of low cost and


The history of ecological studies on the Indus River Dolphin (Platanista minor) is reviewed and constraints on counting the dolphins are critically assessed. In spite of its limitations the downstream transect count technique is the best practical solution at the present time. It is suggested that more reliable objective recording techniques need to be developed in order to assess accurately the size of the population and the use of recording hydrophones (PODS) is suggested. Since the Dolphin Reserve was set up in the early 1970s, the number of dolphins steadily increased. Although since the mid-1990s the number seems to have reached a plateau but this may be due to the variability of the counts.


A new digital beam-forming technique is proposed for the reflective-mode ultrasound imaging. This technique is based on the holographic beam-forming using uncorrelated transmitting pulses, and it permits high speed data acquisition with simple hardware. In the proposed method, a carrier signal is modulated with uncorrelated pulse sequences, and ultrasound pulses emitted from transmitters construct a wavefront of non-directional power propagation. Beam-forming on the transmitting and receiving stages can be accomplished numerically using delay-and-sum operation and correlation. Point spread function (P.S.F.) of the imaging system is derived as a function of the range and azimuth differences. From the analysis of the P.S.F., it is shown that both the range and azimuth resolution limit is sufficiently small when the waveforms are uncorrelated to each other and the sum of their auto-correlation functions has a single sharp peak, even if the band-width of each waveform is narrow. We consider the utilization of Walsh functions as the modulating sequences. An experimental system utilizing a 50kHz airborne sensor array is constructed. This system has a linear array which consists of 16 transmitters and a single receiver. The experimental results indicate the feasibility of the method. Computer simulation shows that the additional receivers improve the P.S.F. of the system.


Control loop performance assessment (CLPA) techniques are crucial for optimizing any plant or machine. They can bring huge energy and material savings and increase product quality. In this paper, the employment of running discrete Fourier transform (RDFT) in CLPA field is discussed. The first part of the paper documents the development of new RDFT function block which is suitable for CLPA. The paper focuses on implementation aspects whose aim is to minimize the number of arithmetic operations and to avoid numerical errors which are cumulated in many algorithms when running over longer time period. Then three RDFT applications are introduced. They are mostly dedicated to CLPA area: The changes in RDFT output help to detect increasing valve stiction or reveal a cause of oscillations in the loop. RDFT can be also used for continuous monitoring of process changes at particular frequencies. The most advanced problem presented is the estimation of special performance indices. More specifically, key samples of sensitivity function are gained and compared to the reference ones. Inspired by the model free design techniques, only a minimum a priori information about the process is assumed. The authors believe that the presented ideas will be suitable for both academic and industrial sphere.


A series of N′-(3-amino-1H-isoindol-1-ylidene)alkyl(aryl,heteroaryl)carbohydrazides have been synthesized in good yields and their structure and conformational behavior in the solid state and in solution have been studied by X-ray crystallography, NMR spectroscopy, and quantum calculations. (E)/(Z) amide-type isomerism and the dependence of the isomeric ratio upon steric effects and solvent polarity are discussed. The thermodynamic parameters of (E) (Z) isomerization were determined by 1H NMR dynamic spectroscopy. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)


The execution architecture determines largely the realtime and performance behavior of a system. Hard real time is characterized as "missing a deadline" will result in system failure, while soft real time will result "only" in dissatisfaction. An incremental design approach is described. Concepts such as latency, response time and throughput are illustrated. Design considerations and recommendations are given such as separation of concerns, understandability and granularity. The use of budgets for design and feedback is discussed.


In this paper, a new active neutral point clamped (ANPC) five-level (5L) inverter is proposed. The conventional ANPC output voltage is half of the input voltage. To rectify the above problem, a floating capacitor is used to boost the output voltage equal to the input voltage, which further reduces the size of the dc-link capacitors. In addition to this, the proposed topology does not need any sensors to balance the floating capacitor, which minimize the complexity of the inverter. Further, in the proposed topology, the neutral point is directly connected to the mid-point of dc-link capacitors, which reduces the leakage current and common mode voltage due to the presence of two clamping diodes. Moreover, a new carrier signal is introduced, and the advantages are discussed. The performance of proposed 5L inverter topology is analysed in terms of dynamic loading condition. To show the superiority of the proposed topology, it is simulated in MATLAB and results are discussed.


Abstract : The purpose of this study was to compare the performance on climbing Bachman's ladder rungs in adolescents with high and low levels of trait anxiety (TA) who self-set their goals. We tested the hypothesis that those who self-set goals and scoring low in TA would show superior performance on retention and transfer than those who self-set goals scoring high in TA. The 40 participants [male and female; age 15.81±1,01 (M±SD) years] who took part in the experiment were selected from a primary sample of 465 adolescents. Two groups were formed (high TA and low TA) and the task consisted of climbing the rungs of the Bachman's ladder. The design was comprised of four experimental phases: 1) acquisition (15 blocks of 10 trials), 2) immediate transfer (one block of 10 trials); 3) delayed transfer (one block of 10 trials), 4) retention, (one block of 10 trials). The analyses of variance indicated significant effects for the main factor "block" in acquisition; the performance in the initial blocks was worse than in the last blocks. No group differences were detected on either acquisition or transfer and retention. Thus, our findings suggest that the practice undertaken through an active engagement of the learner via self-setting of goals enhanced the performance of all participants during acquisition. The lack of differences in performance between high and low levels of TA was probably due to the offset caused by the self-setting of goals. Key Words: Goal setting, self-control, anxiety, adolescents, motor learning.


Silicone elastomers require replacement due to degradation of mechanical properties and deterioration in color over time. Recently, various nanoparticles have been incorporated into the silicones to reinforce their physical and mechanical properties. The purpose of this study was to evaluate the effect of nanosized particle addition on the color stability of a commercial RTV maxillofacial silicone elastomer submitted to an accelerated aging.       The nanosized particles (titanium dioxide and silaned silica) were added, 10% by volume, into a maxillofacial elastomer. The samples (n=10) were polymerized in an oven according to the manufacturer's recommendations. Color measurements were performed using digital spectrophotometry according to the CIE L*a*b* color system. The samples were subsequently placed into an aging chamber for 168 h. The second color measurement of the samples was performed after the aging process. Data obtained from the measurement was recorded and assessed by (ANOVA) (α=0.05). The highest color stability was obtained with the silica and the TiO 2 group samples; the lowest color stability was obtained with the control group samples in this study. However; no statistically significant difference in discoloration was observed in the ∆E values between the groups (p > 0.05). The results of this pilot study revealed that the addition of nanosized TiO 2 and silica particles used as reinforcing agents did not cause any color degradation of an A-2000 silicone during the first 2 months. Further studies should be done on the effect of such nanoparticles in long term aging procedures on the color stability of maxillofacial elastomers. Key Words: Color stability, nanoparticles, maxillofacial silicones.


We Americans are uneasy about developments we see taking place around the world and we are confused and divided over what to do about them. There are convincing signs that detente, the vaunted centerpiece of our current foreign policy, is significantly eroding. Our government is at odds with the Soviets in various parts of the world in ways reminiscent of the Cold War. The SALT Talks are lagging. There is reaction in this country, ranging from enlightened concern to blind hysteria, over the Soviet military buildup that was going on steadily during the years that we were mired down in Vietnam. In the meantime, we are worried about the growing strength of the Communist parties in Western Europe, the turmoil in Africa, the unresolved Arab-Israeli tensions, the threatening mystique of changing leadership in China, and volatile situations in Korea and other countries of western Asia, in Portugal, Spain, Cuba, and Panama. There is also major anxiety over the emerging assertiveness of Third World countries, the demonstrated power of commodity cartels, and the bristling hostility of many developing nations toward the United States. If we were to rely on official actions and pronouncements by our government for guidance, it would seem that very little has changed in our international outlook in recent years. Yet we know that since Vietnam there have been profound changes in the public perception of America's future role in the world. There is a significant gap between the public unease about where we are going in international affairs and the directions in which our leaders proclaim we are heading. In response to new needs and changing conditions of the post-Vietnam era, the American people have signaled a vague, but nonetheless strong, feeling that the old policies of power diplomacy and military intervention in countries where our national interest is not clearly at stake are no longer acceptable. Congress, more closely responsive to the electorate than the Administration, has asserted from time to time a newly developed sense of responsibility in foreign affairs, an advent that has been bitterly opposed and condemned by the Administration. So our foreign policy is locked in dubious battle between new needs of a changing world order and old policy patterns rigidly insisted upon by our leaders. The strategic strength of our country, despite dire warnings from some quarters that our military power is dangerously slipping, is such that we have some limited time to sort out our priorities and get our bearings. But the clock is running and soon we must make some hard choices about foreign and defense policy for the future that will serve our true national interests and command the support of the people. With regard to this countdown, we would do well to remember Churchill's warning spoken in England's darkest days: "If we open a quarrel between the past and the present, we shall find that we have lost the future."


Thick sandstone roof in the roof strata construction is one of the main influence factors of rock burst.The main identifying base of the tendency of rock burst is from laboratory result and the result is different from fact widely.Combined coal and rock from main mining coal seam in Sanhejian Colliery is used to test the tendency of rock burst and the results provide basic parameters for the rock burst monitoring and prevention and control in mining face with high tendency of rock burst in Sanhejian Colliery.


As a reaction to the rapidly changing environment, organisations increasingly use agile project management (APM) methods to develop innovation. The associated process changes necessitate the adaption of organisational structures and control systems. This study draws on Simon's Levers-of-Control framework (LOC) to explore the impact of different control levers on innovation project performance. Based on a survey of 316 project managers and product owners, the results suggest that the use of interactive project control systems and project-internal belief systems has a positive impact on the innovation outcome, regardless of the degree of agility of the project. Furthermore, we reveal that a strong project environment leads to increased use of control mechanisms on the project level and has a conducive impact on innovation project performance. The study is among the first to apply the LOC on the project level and integrate it into the agile context.


Commentators who lament that Kant offers no concrete guidelines for how to set up an ethical community typically neglect Kant's claim in Religion that the ethical state of nature can transform into an ethical community only by becoming a people of God—i.e., a religious community, or "church." Kant's argument culminates by positing four categorial precepts for church organization. The book's next four sections can be read as elaborating further on each precept, respectively. Kant repeatedly warns against using religious norms to control people. Accordingly, he explicitly forbids the true church from adopting any standard form of political governance; it must aim to be radically non-political. Nevertheless, churches organized according to Kant's non-coercive theocratic model contribute something essential to the ultimate political goal of achieving perpetual peace and an end to war: by approaching the ultimate ethical goal (the highest good), the true church offers an antidote to normative fragmentation.


Large elongation in one definite direction of a crystal of cubic symmetry is considered. The equations of second order elasticity theory are applied. In this approximation three constants of the second order and six constants of the third order characterize the crystal. The stress is a function of the elongation direction. The elongation directions for which the stress reaches an extreme value have been analyzed.


The proliferation-differentiation behaviour of human alveolar bone cell cultures grown for 32 days in conditions that allowed the complete expression of the osteoblastic phenotype was significantly affected by the continuous presence of parathyroid hormone, 1, 25-dihydroxyvitamin D(3), or dexamethasone. Parathyroid hormone and, in particular, dexamethasone significantly induced the differentiation of osteoblastic cells. Moreover, cultures exposed to these hormones presented an earlier appearance and higher levels of alkaline phosphatase, and an increased ability to form calcium phosphate deposits in the extracellular matrix.

The author analyzes the position of the Supreme Soviet of the Russian Federation and the pro-presidential Ministry of Foreign Affairs in relation to a political settlement in Transnistria. The participation of the Transnis-trian special police force "Dniester" in the events related to the Supreme Soviet assault on October 3-4, 1993 is briefly assessed.


The purpose of this study is to try to find a protocol defining a clinical diagnostic procedure for the patients to be admitted to the authors' Institute to receive treatment for either suspected or confirmed diagnosis of spine deformity in Prader-Willi syndrome (PWS). The aim is to evaluate every subject from the diagnostic point of view, assessing variability of clinical expression and evolution of spinal deformity in the light of the related genetic aspects, thus providing a univocal protocol. The present series only includes patients (18 cases) with PWS, 7 hospitalized for surgical treatment of scoliosis, 11 followed-up at the authors' institute only for conservative treatment of scoliosis. Both BMI tracks (weight/height2) and BMI Z-score (only for children older than 2 years) were assessed. Moreover, the GH treatment was evaluated for each group of patients as follows: being administered, suspended or no treatment. Finally, the gene was compared with BMI. No relationship was observed either between GH treatment and mean BMI or between genetics and mean BMI. More patients should be seen by the authors to confirm or refute the current findings.


Background and Purpose. Inappropriate patient sexual behavior (IPSB) is defined by Johnson and colleagues as any "verbal or physical act of an explicit, or perceived, sexual nature, which is unacceptable within the social context in which it is carried out."1(p688) IPSB is pervasive in clinical practice, experienced by as many as 85% of physical therapists during their career, and has significant negative consequences for both clinicians and patients.2,5,6 Therefore, entry‐level physical therapist education should prepare students to effectively address such situations. The purpose of this article is to propose a strategy for training physical therapist and physical therapist assistant students to competently respond to IPSB. Position and Rationale. Curricula should include the definition and prevalence of IPSB, legal rights and ethical obligations, factors influencing IPSB, assertive techniques, and instruction in effective documentation. Education that highlights both a commitment to the patient's and the clinician's rights to protection will assist in the development of professional behavior. The inclusion of role‐play and case studies encourage students to consider their own values and practice formulating responses. Training in assertiveness techniques and tools for proper documentation will prepare students for real‐world application. Conclusion. Addressing IPSB is a complex task that is often highly charged emotionally for both patient and professional. Providing preparation as part of physical therapist education increases the likelihood of positive outcomes.


Aimed at horizontal tunnel model with the same width and different heights, using CFD technology, influences of environmental temperature, fire heat releasing strength, section shape on critical wind velocity were analyzed. Hydraulic height was selected as characteristic length and variational relation of dimensionless critical wind velocity corresponding to the 2 kinds of tunnel models vs heat releasing strength was gained, which was in a good agreement with the results of reduced-scale and full-scale tunnel fire tests. Based on CFD simulating result, the short-comings of Kennedy formula were analyzed. The result shows that Kennedy formula should be avoided to use in determining fire ventilation longitudinal control wind velocity for long tunnel.

High-resolution dedicated cardiac SPECT systems with CZT detectors have a great potential to provide 3D molecular breast imaging of sub-cm tumors. In this study, we investigated the feasibility of breast imaging using a dedicated cardiac SPECT system (GE Discovery 530c/570c) by simulating different lesion sizes, positions, and contrasts. Noise-free NCAT phantom data with 99mTc-tetrofosmin were simulated. The lesions diameter was 5 mm, 8 mm and 10 mm, respectively, located at the center and chest wall of both left and right breasts. Various lesion contrast levels ranging between 5:1 and 40:1 were simulated. A realistic hybrid simulation was achieved by combining the projections of a simulated 8 mm lesion and the projections of the normal left breast of a 99mTc-Sestamibi myocardial perfusion SPECT patient at supine position. For most lesion contrasts, 10 mm-diameter and 8 mmdiameter lesions can be detected visually. However, 5 mm lesions can only be detected with high contrasts. Lesions located in the right breast were better visualized than the ones located in the left breast due to the impacts from the adjacent organs with high activity, such as the heart and liver. Lesions at the center of the breast had higher contrast than the lesions at the chest wall, which were closer to high activity organs. Higher number of iterations in the reconstruction led to improved tumor contrast, at the expense of increased non-uniformity in the background. In the hybrid simulation, the 8-mm lesion was detected clearly at the center of the breast with realistic tracer distribution in the background. The preliminary results suggest that it may be feasible to detect sub-cm breast tumors located at both central breast and chest wall using the dedicated cardiac SPECT system investigated.


Body temperature is frequently measured during in vivo studies, as it can provide important information around the health and welfare of an animal. Current methods of body temperature measurement used within GSK are regulated procedures and invasive. The Home Office requires research establishments to find and implement more refined ways of working. Therefore, there is a desire to find new methods to measure body temperature which can be used in research laboratories that are non-regulated and refined, but still reliable and accurate. This study investigated whether the FLIR E95 Thermographic Camera could be used as an alternative non-invasive and non-regulated method to measure body temperature in rats and whether it is as accurate as invasive and regulated methods such as the rectal probe and subcutaneous temperature transponder. Measurement of body temperature investigations were split into three phases and used the thermographic camera compared to these two methods in Crl:WI(Han) rats. Phase 1 investigated which site on the animal provided the most accurate and appropriate temperature reading using the thermographic camera. Phase 2 investigated whether the thermographic camera could detect a change in body temperature, while Phase 3 investigated whether the thermographic camera was practical in a research scenario. The data shows that the FLIR E95 Thermographic Camera on the eye and ear were the best comparators in terms of accuracy to the rectal probe and Plexx microchip. The FLIR E95 Thermographic Camera did not detect a change in temperature as well as the Plexx microchip or rectal probe, however the most aligned methods were the Plexx microchip and camera (ear). The FLIR E95 Thermographic Camera was easy to use, however the Plexx microchip remains the most practical temperature collection method. The FLIR E95 Thermographic Camera should be used alongside the Plexx microchip or rectal probe on a future study in order to further assess whether the camera can detect a change in temperature.

This study was carried out investigate the removed T-P, T-N and anion surfactants using SiO₂-Al₂O₃-CaO type porous ceramic in wastewater treatment system. The phosphorous, nitrogen and anion surfactants removal efficiencies were examined by using artificial waste water(T-P : 115∼170 ㎎/L, T-N : 56∼163 ㎎/L and anion surfactants : 10∼31 ㎎/L, BOD : 200ppm, Turbidity : 950NTU). The results showed that the ceramic was effective material as a adsorbent due to the structure and porosity. It was found that anion surfactants removed was 85∼95 %, phosphate removed was 92 % and nitrogen removed was 90 % in artificial wastewater. Agitation process was more effective than aeration process in that case of nitrogen removal system using porous ceramic.


Aim To assess the trend of changes in the evaluation scores of faculty members and discrepancy between administrators' and students' perspectives in a medical school from 2006 to 2015. Materials and methods This repeated cross-sectional study was conducted on the 10-year evaluation scores of all faculty members of a medical school (n=579) in an urban area of Iran. Data on evaluation scores given by students and administrators and the total of these scores were evaluated. Data were analyzed using descriptive and inferential statistics including linear mixed effect models for repeated measures via the SPSS software. Results There were statistically significant differences between the students' and administrators' perspectives over time (p<0.001). The mean of the total evaluation scores also showed a statistically significant change over time (p<0.001). Furthermore, the mean of changes over time in the total evaluation score between different departments was statistically significant (p<0.001). Conclusion The trend of changes in the student's evaluations was clear and positive, but the trend of administrators' evaluation was unclear. Since the evaluation of faculty members is affected by many other factors, there is a need for more future studies.


Objective To investigate the predictive value of ambulatory electroencephalography (AEEG) in monitoring the recurrence of epilepsy after medication withdrawal. Methods A five-year follow-up study was performed in 265 cases,antiepileptic drugs of whom were withdrawn after the onsets of epilepsy had been controlled thoroughly for over three years and the AEEGs had become normal;the AEEG examination was performed at least once per year for each patient. Alterations in AEEGs of the cases with medication withdrawn at the first visit,during the treatment,and before and after medication withdrawal were analyzed to find out the possible links between recurrences of epilepsy after withdrawal and AEEGs alterations before and after withdrawal.Results A total of 47 cases recurred clinically in the study.The cases with normal AEEGs at the first and during the treatment had a relatively low recurrence rate,8.1%,but the cases with epileptiform AEEG discharges had a recurrence rate of 25.0%,especially high for those with epileptic waves in the focal temporal, frontal,parietal or occipital lobes,or multiple foci.Moreover,the clinical recurrence rates were also high in cases with epileptic waves reoccurred in EEGs during AEEG follow-up study after medication withdrawal.Conclusion The alteration in the AEEG is one of the significant clues for the determination of the recurrence of epilepsy and it has certain predictive value in monitoring the recurrence of epilepsy after medication withdrawal.

The metabolite screening of Haliclona viscosa yielded 21 3-alkyl pyridinium alkaloids whose structure was unknown before (haliclocyclin C, haliclamine K and J, dehydro-haliclamine J, dehydro-viscosaline E1, viscosamine D, dehydroviscosamine C and D) or had previously been suggested and could be refined or confirmed (haliclocyclin F1, haliclamine E and F, dehydro-haliclamine C, D, F, ambidehydro-haliclamine F and didehydro-haliclamine D, viscosaline B1, B2, E1 and E2, viscosamine B). The structure identification of haliclamines based on a mass spectrometric fragmentation study of the haliclamines; it forms part of this thesis and is enclosed in manuscript form to be published. New viscosalines and viscosamines were identified by evaluation of the high resolution mass spectra of a known viscosaline and viscosamine, and the observations concerning their fragmentation behavior are described in the presented thesis. Structure elucidation of 3-APAs that contain double bonds in the alkyl chains is in progress, as is the structure elucidation of still unknown 3-APAs in the crude extract eluting before 12 min and after 23 min.
In the progress of developing a method that allows metabolite screening of different sponges by MALDI-MS, the Caribbean sponge Stylissa caribica was found to possess previously unknown compounds which were identified as the new cyclic heptapeptides stylissamides A-D. The stylissamides are very rich in proline and especially stylissamide B shows an interesting combination of amino acids, with three out of four prolines being arranged consecutively. Imposed by this configuration, the NMR signals of the stylissamides overlapped strongly but the structure elucidation could finally be achieved by a combination of extensive NMR and MS experiments.

Background. Coronavirus disease 19 (COVID-19) infection has been a global pandemic since late 2019. Clinical manifestation ranges from mild to severe. Even though most COVID-19 patients recover fully from the disease, approximately 5–10% experience prolonged symptoms for several months following the acute COVID-19 phase, defined as long COVID-19 syndrome. Rehabilitation therapy is needed for them to overcome their symptoms and improve their functional capacity. This systematic review aims to discuss rehabilitation therapy for a patient with long COVID-19 syndrome.
Method. A systematic review using PubMed and Google Scholar was conducted based on PRISMA guidelines. Inclusion criteria were study about rehabilitation therapy for long COVID-19 patients. Exclusion criteria were letters to the editor, editorial or commentary reports, and studies not available in full-text and not in English or Bahasa.
Result. Nine studies are included in this systematic review consisting of two consensus statements or recommendations, one cohort retrospective study, two case studies or case reports, one review and three experimental studies. The recommended rehabilitation program pathway using a three-tier model depends on the severity of the disease. Several rehabilitation exercises for long COVID patients include cardiorespiratory rehabilitation, breathing exercise, therapeutic exercise, and even traditional Chinese fitness models such as Liuzijue exercise.
Conclusion. Rehabilitation therapy exercise helps to improve the patient's breathing effort, improving dyspnea and muscle strength.
Keywords: long COVID-19 syndrome, physical rehabilitation, post-COVID-19 infection, rehabilitation therapy

We used pottery instead of Wear-resistant cast iron for improving the performance of forming sleeve. The structure of the forming sleeve was analyzed with the mechanical module of a soft named Pro/engineer in this paper. The result indicated that the program was feasible. With the sensitivity analysis we identified the suitable angle for the sleeve.


Outflows driven by active galactic nuclei (AGNs) are often invoked as agents of the long-sought AGN feedback. Yet, characterizing and quantifying the impact on their host galaxies has been challenging. We present Gemini Multi-Object Spectrograph integral field unit data of six local (z < 0.1 ?> ) and luminous (L [ O III ] > 10 42 ?> erg s−1) type 2 AGNs. In the first of a series of papers, we investigate the kinematics and constrain the size of the outflows. The ionized gas kinematics can be described as a superposition of a gravitational component that follows the stellar motion and an outflow-driven component that shows large velocity (up to 600 km s−1) and large velocity dispersion (up to 800 km s−1). Using the spatially resolved measurements of the gas, we kinematically measure the size of the outflow, which is found to be between 1.3 and 2.1 kpc. Owing to the lack of a detailed kinematic analysis, previous outflow studies likely overestimate their size by up to more than a factor of two, depending on how the size is estimated and whether the [O iii] or Hα emission line is used. The relatively small size of the outflows for all six of our objects casts doubts on their potency as a mechanism for negative AGN feedback.


Diphenyliodonium salts readily react with [IrX(CO)(PR3)2] (X = Cl, Br; PR3 = PPh3 or PMePh2) to yield iridium(III) σ-phenyl complexes of general composition [IrXY(C6H5)(CO)(PR3)2] (Y = Cl, BF4). The possible structures of these compounds, and their occurrence in the decomposition of iridium aryldiazenato complexes, are discussed.


Published evidence relating the rate of fading of a colorant to its physical state in the substrate, and to the photochemical layer effect, is discussed, and a new theoretical Model of light fading is proposed. In this the rate of oxygen diffusion from the atmosphere is considered, first in traversing the polymeric substrate, and then in entering an embedded colorant particle, under illumination. Expressions are derived which show that the rate of fading should vary with I/a2 (a = radius of particle), for large particles. As the particles become smaller, the rate tends towards a 1/a dependence, and eventually, with very small particles, it is independent of their size. Recently reported rates of fading of pigments of measured particle size gave results in agreement with the present treatment; the smallest particles thus considered are of the same order of magnitude as those of high light fastness direct dyes in cellulose, as observed by electron microscopy. Thus the model may be applicable to at least some water-soluble dyes as well as pigments.
