Magnetic fluid is a colloid of magnetic nanoparticles. Using of magnetic fluids in technical devices demands applying of strong non-uniform magnetic fields for a long time. One of the most widespread magnetic fluid devices are magnetic fluid seals of mobile shafts, magnetic fluid supports, bearings, acceleration and angle of inclination gauges, devices for information input in the computer and etc. These devices demand high quality of used fluids. Processes of magnetophoresis and Brownian diffusion in magnetic fluid lead to concentration of magnetic particles in the areas with higher intensity of magnetic field and increase of fluid magnetization in these areas. A local change of particles concentration in the fluid leads to variation of its physical properties. Formation of aggregates from the particles and the further stratification of magnetic fluid, up to its destruction, may be the most serious consequence of redistribution of concentration of magnetic particles. These factors lead to variation of parameters of magnetic fluid devices; cause disturbance of their normal operation and even failure. Therefore, the consistent, high quality magnetic fluids which are not subject to fast stratification in a non-uniform magnetic field are necessary for effective work of the devices. The procedure of evaluation test of quality of magnetic fluids is proposed in this paper. The test is based on studying of influence of processes of magnetophoresis and Brownian diffusion of magnetic particles in magnetic fluid on the forces acting on the volume of fluid in an external non-uniform magnetic field. The procedure is developed on the basis of analysis of magnetic force variation in time under the action of non-uniform field of permanent magnets. Methods of determination of stability of magnetic fluid, known at present, demand rather complicated equipment and laborious and complex investigations. Proposed procedure can be used as an express method for evaluation of magnetic fluid quality for usage in technical devices, and it does not need complicated equipment.


Background: Iron deficiency anaemia (IDA) is the most common type of nutritional anaemia which affects people globally. Adolescent period symbolizes the initiating of menstrual period in girls hence, they are at a larger risk for nutritional anaemia. Supplementation, fortification and dietary diversification are the three initiatives for alleviating anaemia. Hence, this present investigation was undertaken with the objective to study the impact of millet based biscuits on haemoglobin level of adolescent girls of Samastipur district. Methods: The haemoglobin level of selected forty adolescent girls aged 17-19 years from Uma Pandey College in Pusa block at Samastipur district were carefully examined before intervention study. Experimental adolescent girls who fell in the Hb level range of less than 8 to 11.9 g/dl were intervened with 250 g of T5 millet biscuit for a period of 45 days in order to complement 1/3rd of the regular need of iron for adolescent girls. Result: The mean increase in haemoglobin level after intervention was found to be 1.24 g/dl in experimental girls which indicated the positive impact of millet biscuits on haematological health of anaemic adolescent girls. The present work will be a complementary contribution towards alleviating anaemia among adolescent girls.


The content and component composition of essential oil of air-dried phytomass and seeds of Anethum graveolens L. were determined. Dill was grown using the organo-mineral preparation Ideal and steroid phytohormone (24-epibrassinolide) Epin-extra. The use of growth regulators increased the yield of green dill (Ideal by 16%, Epin-extra by 6% compared to the control); did not affect the content of essential oil in the herbs of dill and increased the content of essential oil of dill seeds. GC/MS (Gas Chromatography / Mass Spectrometry) analysis revealed differences the ratio of the main components of the essential oil of dill when the use of growth regulators. In the essential oil of air-dried phytomass of plants, compared with the control, the content of alpha-fellandrene (1,3–1,7 times) and limonene (1,1–1,2 times) increased, anethofuran (1,4–1,8 times) and carvone (in 1,4–1,5 times). In the essential oil of dill seeds - increased content of limonene (1,7–1,9 times) and decreased carvone (1,1 times). When using growth regulators, a change in the aroma of plants was observed. The use of the Epin-extra drug caused more significant changes in the content of the major components of the essential oil of dill.

The term "jet -pylon inte raction effects" refers to the noise difference between the jet from an isolated nozzle and the jet from a nozzle pylon combination. There are, however, significant differences in the results reported by different workers for these interaction effects and the reasons for these differences are not well understood. In an attempt to resolve these issues, new numerical calculations and experimental tests have been run for b oth isolated nozzles and nozzle -pylon configurations. The new experimental results are di scussed in a companion paper, AIAA -2005 -2845. In the present paper, these new numerical results are presented together with a discussion of the overall conclusions of this study. It is shown that these flows are extremely sensitivity to small nozzle defo rmations and that much of the data scatter reported in the literature can be explained as being due to small, unintended deviations from nominal test conditions. It is also demonstrated that accurate numerical calculations can be very valuable in the study of these complex flows.

Background: In Burkina Faso, malnutrition is a public health problem. Despite the significant drop in the prevalence of malnutrition since 2009 according to the Directorate of Nutrition, malnutrition is still a major concern with regard to its consequences. The objective of this study was to determine the factors associated with acute malnutrition in children aged 6 to 59 months in the Sabou Health District, Burkina Faso.
Methods: This was a descriptive, cross-sectional study conducted among 343 children aged 6 to 59 months in Sabou Health District, Burkina Faso from August 1st to 30th, 2016. Factors associated with acute malnutrition were dietary factors, family factors, environmental factors, and infectious factors determined using SPSS version 21.0 software. The difference was statistically significant for P-value of less than 0.05.
Results: The prevalence of global acute malnutrition in the district was 9.0%, of which 2.6% was severe according to the Brachial Perimeter. Several factors were associated with acute malnutrition in children under 5 years of age in the Sabou health district. Indeed, morbidity was a factor associated with acute malnutrition in children with a P-value of 0.007. The low dietary diversity experienced by food-insecure households was also associated with acute malnutrition in children. Infant and young child feeding practices, i.e., inadequate introduction of complementary foods and low dietary diversity to children were among the factors associated with nutritional status (P = 0.007). Among mothers, 87.5% had heard of malnutrition, 66.5% did not recognize the signs of malnourished in their children, and 92.4% were unaware of the consequences of malnutrition.
Conclusion: Based on the results, initiatives and programmes should be established for women, the bearers of life, to enhance their empowerment and educate them with regard to the integral growth of children, the builders of tomorrow.

We have measured the dielectric relaxation of neat cis/trans-decahydro-naphthalene (decalin) in its supercooled regime as a function of temperature. The fragility of this nonaromatic molecular glass former is extremely high, m=147, and the distribution of relaxation times in terms of the stretching exponent is accordingly wide, β≈0.33. Regarding molecular organic liquids, such high fragilities have been observed before only for aromatic systems, e.g., toluene and triphenyl-phosphite. It turns out that the structural relaxation of neat decaline differs significantly from that of the 17.2 mol % chlorobenzene doped counterpart reported earlier.


We have often heard the saying , "What goes up must come down", but all too frequently have not given the concept too much thought. It now has become a very important issue not only in this country, but everywhere on the planet earth and is the center focus of the acid rain debate. The debate today does not question the statement given above, but rather addresses the tougher problem of "When something goes up how, when and where does it come down?". A related question might be "When it comes down, is it beneficial or harmful to its final resting place?". A further important question is "Is the acidity of precipitation increasing and is it spreading to larger areas in the U.S. and beyond its borders?". The answers to these questions are central to the establishment of policy regarding how to deal with the national and international concerns about acidic deposition.


as one of the means of solving the problems, such as the loose of internal management , malfunction of the business system ,untrue statement of accounting information and the corruption, internal control has been paid more and more attention by the society. But the actual state of internal control in the enterprises of our nation is not optimistic. The author summarizes seven points of the actual state of internal control, analyses the cause of formation and at last brings forward the means of betterment.


Natural products, their derivatives and traditional remedies have an uprising attention in drug discovery approaches [1-3]. Natural products are characterized by their structural diversity so; they could be utilized as biological function modifiers [4,5]. This open the door for the development of new technologies in discovering new drugs based on natural products' screening, because they are a rich wealth of bioactive compounds [5,6]. Yet, its poor aqueous solubility, inadequate permeability, and suboptimal bioavailability limited their uses. Therefore, several approaches have been developed to improve solubility, permeability and bioavailability of natural products [7,8].

Previous data on incorporation of glucose C-14 into glycogen by the rat diaphragm had suggested that this synthetic pathway was unaffected by the albumin-associated insulin antagonist. To test the hypothesis that only the transport functions of insulin were blocked by this antagonist, studies on two insulin-stimulated intracellular pathways independent of transport were carried out. The increase in tissue levels of the I form of glycogen synthetase seen with insulin was not affected by antagonistic albumin (human fraction V). The D form of glycogen synthetase was also unaffected. However, insulin-stimulated adenine-8-C-14 incorporation into RNA was completely abolished by this albumin. A nonantagonistic albumin (bovine fraction V) by itself increased RNA synthesis indicating that the inhibition of insulin-stimulated RNA synthesis was not a general property of the albumin molecule. The physical-chemical and metabolic characteristics of the albumin-associated antagonist are summarized and are considered to be incompatible with the postulated physiological role for this insulin antagonist.

In this paper, we report on a research project in progress in which we are attempting to establish and maintain an ICT-mediated math knowledge-building community. The paper first identifies why math knowledge-building communities are very difficult to establish and maintain and then provides evidence to support that these difficulties can be overcome by the inclusion of model-eliciting problems and new iconic math representation tools into the computer-supported collaborative learning (CSCL) environment.


English as a multinational and multicultural language can help us know more about the world,but we should also have the ability to introduce our own culture to the world because there are so many treasures in our tradition.In order to investigate how well college English education in China prepares students for communicating in English about Chinese culture,the investigation was conducted in the forms of questionnaires and interviews and the results show that Chinese culture has been much neglected in college English teaching and that the majorities are unable to discuss Chinese culture in proper English.The authors argue that college English can play a role in preserving our culture and in English class more Chinese topic should be introduced.


Investigation of element content by isoionic emissive spectrum in overwinter and twomonth chemical treated longan showed increasing in flowering of the tree with increasing of chloride content in leaves. The chloride content increased more than 3.7% during winter and 108.7% after chemical treating for two months, which may induce various scale of flowering in longan trees, respectively.


ABSTRACT Green synthesis is a more eco-friendly approach compared to the chemical and physical methods. This simple green eco-friendly method was utilized to obtain silver nanoparticles mediated by an aqueous leaf extract as a precursor. The silver nanoparticles mediated by an aqueous solution of Daucus carota L. leaf extract (DCLE) as bio-reducer and stabilizer agents are described. The AgNPs were characterized using FT-IR, UV-Vis, PXRD, and TEM. Antimicrobial activities of the samples were investigated against drug-resistant bacterial isolates using the disk diffusion method, while in vitro cytotoxicity assay by MTS end-point and xCELLigence real-time assays. The synthesized AGNPs from DCLE exhibited face-centered cubic phase with average particle sizes of 18.26 (±6.86) nm and 16.81 (±7.72) nm for AgNP05 and AgNP01 respectively. The scavenging ability of DPPH radicals by the nanoparticles was studied for their antioxidant potentials. The study revealed that the compounds are capable of scavenging DPPH radicals in a dose-dependent pattern (IC50 = 2.61 ± 0.58 μM for extract, 2.79 ± 1.75 μM for AgNP05, 2.84 ± 0.96 μM for AgNP01). Antimicrobial results showed that the nanoparticles possess higher activities. Cytotoxicity of the nanoparticles (0.00 μg/ml – 100 μg/ml) against U87MG brain glioblastoma cells, showed ED50 = 87.31 and 109.48 μg/ml. GRAPHICAL ABSTRACT


the purpose of this paper is to present a method called virtual assembly technology based on natural gesture. In the proposed method, five Leap Motions are fixed on the table to measure the position of the hands. Due to the tracking errors and the noise of equipment, the measurement errors will increase over time. Therefore, we use Kalman Filter and Particle Filter to evaluate the position and orientation of our hands. Then we use 3D Max to build the joint model of our hands, and OSG (OpenSceneGraph) to refactor the model of the hand. We use k-DOPs collision detection algorithm to detect collisions between hands model and human model. Then we use noncontact force feedback to make the operator experience the drag force like in a real environment, so that the operator can use natural gesture to do various assembly operation on the parts of the products in an interactive virtual assembly environment. Keywords-virtual assembly; kalman filtering; leap motion; force feedback.


Summary Nucleolytic activities from two plants of Leguminosae family were determined in order to consider if the nucleases of plants which belong to the same family or to the same species responded in similar ways to stress conditions during growth. Growth parameters of both plants were examined in parallel. In detail, seedlings from two plants, alfalfa ( Medicago sativa L. cv. Luzerne Euver) and lentil ( Lens culinaris cv. Thessalia), showed significant differences in response to iso-osmotic solutions of NaCl (100 mmol · L −1 solution equivalent to conductivity 8.0 dS m −1 ) and mannitol (190 mmol · kg −1 ). Plant height and dry weight of mannitol/NaCl-treated seeds in both plants were lower in comparison to controls (water). Mannitol stress reduced height and dry weight in alfalfa seedlings more than did NaCl. By contrast, lentil seedling growth was inhibited more by NaCl stress than mannitol. In addition, DNase and RNase response to mannitol stress differed in each plant compared to the controls. Mannitol stress induced a sharp increase in DNase- and RNase-specific activity during the initial stages of alfalfa seedlings' growth, followed by a decrease during subsequent days; in lentil seedlings, these activities were inhibited throughout the entire growth period. NaCl stress inhibited the above activities in both plants. After native electrophoresis on gels polymerized in the presence of DNA/RNA, the overall band intensities confirmed the above quantitative results of alfalfa RNase and DNase activity. In addition, the active gel analysis revealed that the decrease of nucleolytic activities in mannitol-treated alfalfa seedlings was mainly due to the strong reduction of acid nucleases. This is the first report of different non-ionic osmotic response of type I plant nucleases during seedlings' growth. In vitro, the addition of up to 300 mmol/L mannitol did not affect acid and neutral nuclease activity in enzyme preparations extracted, purified, and separated from control and mannitol-treated alfalfa seedlings. Our results suggest that plant nucleases responded in a different way to osmotic stress and ionic stress conditions during seedlings' growth.


Saleh and Das rightly point out that both the speed and the reliability of a transport mode are important factors in the modal choice for freight movements. Their assertion that reliability may have been over‐emphasised is confirmed by a recent Australian study into the modal choice for freight movements between Melbourne and Sydney where speed was the second most often mentioned factor while reliability was only the twelfth most often mentioned factor.


We review our recent experiments on the formation and optical trapping of LiCs molecules, which are photoassociated from a mixed ultracold gas of Li and Cs atoms. The electric dipole moment of the atoms in the lowest vibrational states is measured, yielding the predicted value of 5.5 Debye, and vibrational redistribution due to spontaneous emission and blackbody radiation is observed. We also show preliminary results on inelastic collision between optically trapped LiCs molecules and Cs atoms.


Cardiovascular outcome trials (CVOTs) have yielded transformative insights in type 2 diabetes (T2D) management. However, these successes mask the urgent need for more evidence in young adults with young-onset T2D (YOD, defined here as age of T2D onset <40 years)-a high-risk population that has been essentially excluded from these studies. In 2008, the United States Food and Drug Administration mandated that new diabetes medications be tested in large randomized control trials to rigorously evaluate cardiovascular risk. As a result, new CVOTs were designed to include older people with a high risk of cardiovascular events, thus increasing statistical power to detect small increases in risk. However, pediatric studies suggest that young people with YOD may be far more resistant to the effects of insulin and metformin compared to older people with usual-onset T2D (defined here as onset age ≥40 years). As the future of CVOTs continues to be debated, government regulators, industry sponsors, and researchers should improve the representativeness of phase 4 trials by including more young adults with YOD to better understand diabetes medication effectiveness in this population. Although it may be challenging to recruit enough young adults using traditional methods, there are many innovative approaches to enhance study design, efficiency, participation, and follow-up. The dramatic shift in T2D incidence towards younger ages calls for CVOTs to evolve and become more inclusive to inform practice and policy. This article is protected by copyright.

Rae (this issue) succinctly lays out a number of challenges facing the pediatric psychology profession today. Not surprisingly, while concerns about professional acceptance and the ability to develop standards of care and measures for efficacy are present, the principle source of consternation is financial. Like many of their colleagues, pediatric psychologists find themselves trapped in a reimbursement model that worked two decades ago but is increasingly a poor fit today. I would like to highlight a few of the issues raised by Rae and provide an economist's perspective on them. In particular, I will focus on the issues of: the setting in which care takes place; the types of financial relationships that may be possible; and just who should be ''sold'' on the value of pediatric psychology services. The first issue raised by Rae that deserves additional attention from the profession regards the site at which care is expected to take place. As the article points out, the traditional emphasis on having pediatric psychologists as part of the pediatric hospital staff may be less and less viable as time goes on. There are a number of difficulties with having the hospital be the modal site of care for these services. While it is undoubtedly true that such services are needed, a problem arises when the profession seeks to broaden the scope of services offered away from the support of patients and their families through an acute episode of care, and toward theongoing management of chronic conditions and prevention. Such services are not central to the mission of most hospitals and consequently are ''hard sells'' for the hospital administration. This leads to the perceived personal and professional devaluation of pediatric psychological


A case study is an empirical inquiry that investigates a contemporary phenomenon within its real-life context. The case study research method is popular across various disciplines, however, critics of the method argue that results from this form of research are applicable only to the case studied and cannot be generalized further. In the field of construction engineering and management, the number of papers employing case study research methods over the past decade has increased substantially. The question that arises as the method proliferates is whether case studies are being performed with sufficient validity and reliability to maximize the extent to which the findings can be generalized. Given the unique, project-based nature of the construction industry, in this manuscript, we discuss research design and data collection strategies construction engineering and management researchers can employ to improve validity, reliability and the extent to which they can generalize from their findings.


INTRODUCTION AND OBJECTIVES: Radiologic factors are important for predicting bleeding interventions after high-grade renal trauma (HGRT). We aimed to assess the associations between laceration size and peri-renal hematoma rim distance (HRD) with bleeding interventions after HGRT and also find the optimal cut-off points for these measurements. METHODS: The Genito-Urinary Trauma Study is a multi-center study including data on HGRT (AAST grades III-V) from 14 Level-1 trauma centers from 2014-2017. Patients with initial CT scans were included. 2 radiologists reviewed the scans to extract HRD (largest measure from the edge of the kidney to the hematoma in the axial plane) and size of the deepest laceration. Renal bleeding interventions included: angioembolization, surgical packing, renorrhaphy, partial nephrectomy, and nephrectomy. Diagnostic accuracy was measured using the ROC analysis and the optimal cut-offs were chosen based on the Youden′s index and F-1 score. Mixed effect Poisson regression was used to assess the associations. RESULTS: 326 patients were included. Mean age was 35.0±16.6 y. Injury mechanism was blunt in 81%. Injuries were reported as AAST grades III (60%), IV (33%), and V (7%). Overall, 47 (14%) underwent bleeding interventions including 19 renal angioembolization, 16 nephrectomies, and 12 other procedures. Mean HRD was 2.1±2.0 cm and was higher in the intervention group (4.3±0.4 vs. 1.8±0.1, P<0.001). Mean laceration size was 2.0±1.0 cm and was higher in the intervention group (2.8±0.1 vs. 1.9±0.1, P<0.001). For HRD, a cut-off of 3.5 cm provided the best diagnostic accuracy (sen: 0.62, spe: 0.87, Youden: 0.49, F1 score: 0.51). An HRD ≥3.5 cm was associated with 6.3-fold increase in risk of undergoing bleeding interventions (RR: 6.3, 95% CI: 3.5-11.4). For laceration size, a cut-off of 2.5 cm provided best diagnostic accuracy (sen: 0.62, spe: 0.80, Youden: 0.42, F1 score: 0.44). A laceration ≥2.5 cm was associated with 4.4-fold increased risk of bleeding interventions (RR: 4.4, 95% CI: 2.5-8.0). CONCLUSIONS: Our findings support the use of 3.5 cm cut-off point for hematoma and 2.5 cm for laceration size. These cut-offs may be used as simpler predictors of bleeding interventions. Renal trauma grading may benefit from incorporating additional important radiologic findings. Figure. No caption available. Source of Funding: none


Typically, Romanian university colleges of business require students to pursue basic accounting, economics, finance, and management classes at the undergraduate level or, for the first time, while pursuing studies in the masters of business administration (MBA) program. Generally, university administrators do not impose tax courses on business students (economics, finance, management, etc.) and sometimes do not even require them for accounting students. Administrators likely do not require tax studies because of the combination of their real-world advisors, managers, not truly understanding the value of tax planning in their own businesses let alone in university curricula and few available tax professors. Many real-world managers, universities' advisors, also do not truly comprehend the value of tax planning. With these beliefs then, they generally do not advise university administrators to require tax courses for students who are about to enter the business field. Too few tax professors are available not just in Romania but also globally. Individuals in the tax field earn so much that they rarely consider entering academia because of the pay cut. The paper then provides examples, evidencing the necessity of combining tax knowledge with financial accounting, economics, finance, and management studies. Next, solutions to the lack of professors are discussed. These results are then analyzed with implications for Romanian universities with the conclusion following.


This study reports on the types of academic talk that contribute to enhanced explanatory responses, reasoning, problem-solving and learning. The study involved 10 groups of 3–4 students who were provided with one of three linguistic tools (i.e. Cognitive Questioning, Philosophy for Children and Collaborative Strategic Reading (CSR)) to scaffold the questioning process and promote discussion during small group work. Groups were videotaped as they worked on inquiry-based science activities and the videotapes were fully transcribed to identify those helping discourses that contribute to productive talk and learning. In addition, three vignettes of students' discussions are also presented in order to illuminate the different types of productive talk that the students demonstrated in their groups. In the first vignette, the students predominately engaged in analogizing as a tool for constructing meaning. In the second, productive talk involved mainly asking questions and providing elaborations and statements while the third is characterized by questions, reasons, rebuttals and statements where students essentially demonstrate the full complement of discourses characteristic of productive academic talk. The study provides insights into how students appropriate various stratagems for talking and thinking together while simultaneously communicating their shared intentionality and motivation to complete the task.

Results of variations on a categorical standard-setting procedure for use with performance assessments with multiple performance standards are reported. Panelists were asked to make independent ordinal categorical assignments of student work. Student work came from the administration of 1 of the 1996 Grade 8 National Assessment of Educational Progress Science Booklets. This study focused on the comparability of cutscores using 2 data analysis strategies, the effects of 2 strategies for making the categorical classifications (sorting vs. direct classification), the efficacy of long and short versions of the classification scale, and the effects of discussion on the basic, proficient, and advanced cutscores. The results indicate that there were minimal differences in cutscores across the 2 data analysis strategies. The direct classification approach was more feasible than the sorting approach, at least with the design as it was implemented in this study. The short version of the classification scale yielded comparable results to the longer version and took less time (about 20%) for the panelists to complete. Discussion produced the expected effect of more agreement among panelists. These results should be interpreted with caution due to the small sample sizes.


The intraseasonal oscillation of Tropical Convergence Zones(TCZ) over the Indo-Pacific region has been studied. Both meridional and zonal propagating modes with timescales of about 40 days are prominent over the Indian and West Pacific regions. The mechanisms governing both these modes are reviewed. It is found that ocean–atmospheric interaction plays an important role in modulating these modes. The role of oceans is further highlighted in a series of seasonal forecasts using a coupled ocean–atmosphere model. It is found that forecasts of intraseasonal oscillations show significant improvement upon assimilation of sub-surface ocean data from the ARGO (a global programme to observe sub-surface profiles in the oceans) array of floats.


We report a surprising link between optimal portfolios generated by a special type of variational preferences called divergence preferences (see Maccheroni et al., 2006) and optimal portfolios generated by classical expected utility. As a special case, we connect optimization of truncated quadratic utility (see Cerný, 2003) to the optimal monotone mean–variance portfolios (see Maccheroni et al., 2009), thus simplifying the computation of the latter.


: Formation of cracks is very common phenomenon of concrete structure. It leads to decrease their durability and strength of the structure. Recent research has shown that specific species of bacteria can actually use as a tool to repair cracks and increase a strength and lifetime of public buildings and also reduce maintenance cost. Escherichia Coli is known as E.coli to improve the strength of the cement concrete. The aim of to this project is development of a new type of concrete by introducing bacteria promote self-healing of cracks. This bacteria has been used to induce CaCo 3 precipitation when it comes in contact with water that results in self -healing of cracks in concrete and improve all the properties of concrete. Cement concrete were cast with three different properties of bacteria in the ratio of (5%, 10%, 15%) respectively. The strength properties will be compared with conventional concrete after the curing period of 7 days, 14 days and 28 days.


Musicians use the word, theory, in two quite different fashions *1. One of these ways is, to the best of my knowledge, unique to the profession of music. Used in the phrase, music theory, it commonly refers to the sets of information, skills, and technics covered by courses in notation, ear training, sight singing, harmony, form, analysis, counterpoint, orchestration, and so forth. Providing training in these subjects is a major responsibility for those of us who call ourselves music theorists. The materials presented in these courses are organized on the basis of some set of assumptions about music and musical behavior; but they are, in fact, courses in past or present prac-


Objective: To investigate the main physiological changes on the severe burn patients and the clinical applications of muscle relaxant in these patients.Methods: 50 severe burn(30%) patients were divided into three groups by their skin graft frequencies: skin graft group 1,2,3.The dosage of Vecuronium Bromide,neuromuscular blocking effect,classification of conditions of endotracheal intubation and hemodynamic changes were observed during the operation and the parameters above were made comparisons in each group and between the groups with 50 bone injured patients in the same period.Results: The drug dosages of the severe burn groups in eschar shaving and each skin graft were far more than the bone injured groups(P0.05),there was no significant difference(P0.05);the onset time of muscle relaxant of the severe burn groups in eschar shaving and each skin graft were far more than the bone injured groups(P0.05),the maintain time and recover index were less than the bone injured groups(P0.05),and the tracheal intubation conditions were poor than the bone injured groups(P0.05).After anaesthesia,the MAP of the severe burn groups and bone injured groups had an obvious decrease.And the descending extent of the severe burn groups was more obvious than the bone injured groups;the SpO2 of the severe burn groups had an obvious decrease,while the bone injured groups had no significant change;the HR of the severe burn groups had no significant change,but the bone injured groups had descended obviously.Conclusion: The hemodynamic changes of the severe burn patients are not stable,and the crust excision and skin grafting of the muscle relaxant dosages have increased and the neuromuscular blocking effect has decreased,the tracheal intubation condition has gone down,and higher anesthesia requirements are needed.


Abstract The Federal government is seeking to increase the proportion of Australians with bachelor degrees and to increase the proportion of low SES students in higher education. This will focus attention on degree completion rates for all students, including non-traditional students who have previously been reported as having lower higher education completion rates. This quantitative study of 79 students from diverse backgrounds reports their bachelor degree completion rates by 2010, following their participation in discipline-linked further education courses in 2005. The study found that these further education articulators have a higher bachelor degree completion rate than 'other' students reported in previous national studies, that their completion/continuation rates are comparable with all students including in specific fields of study, and that poor academic performance is not the main reason that articulators discontinue study. It concludes that discipline-linked further education courses can contribute to the achievement of the Federal government's higher education growth, and equity achievement targets.

1. In August last I presented to the Society a memoir on the inheritance of coat-colour in thoroughbred horses, and of eye-colour in man. This memoir, which was read in November of last year, presented the novel feature of determining correlation between characters which were not capable à priori of being quantitatively measured. The theoretical part of that memoir was somewhat brief, but I showed by illustrations that the method could be extended to deal with problems like the effectiveness of vaccination and of the antitoxin treatment in diphtheria.


For centuries drought has come and gone across northern sub-Saharan Africa. In recent years, water shortages have been most severe in the Sahel—a band of semi-arid land situated just south of the Sahara Desert.


This chapter describes the use of semistructured play in the Children of Divorce Intervention Program (CODIP), a developmentally based, preventive intervention for children of divorce. The goals, objectives, and key components of the intervention and implementation process are described, as are a number of outcome studies that provide a solid evidence base for the program's effectiveness. Implications for replication and transportability in various settings are also discussed.


The development of artificial reverberation has made considerable progress in recent years. Simultaneous advances in knowledge and computational power have allowed for a rapid development and application in the design of virtual room environments. Within such situations, simulating room acoustics is critical for producing a convincing immersive experience. This research explores the application of a multi‐channel loudspeaker setup that can be employed in simulating such an environment. An algorithm to shape and vary the spaciousness within the context of an artificially generated reverberation is implemented. The pseudo‐random properties of reciprocal maximum‐length sequences (R‐MLSs) allow for a deterministic decorrelation between all channels. The use of R‐MLS also provides several advantages over using traditional random noise. This paper will discuss the potential applications in creating virtual spaces and variable acoustic environments using multiple channel systems.


The utility model discloses a coating system capable of enhancing the adhesion of an aluminum-coated layer. The coating system comprises a coating groove, a coating roller, aluminum-coated paper, a drying oven and a corona treatment device, wherein the coating roller is arranged above the coating groove; the aluminum-coated paper passes through the coating roller and paper feeding rollers in front of and behind the coating roller; the back side of the aluminum-coated paper passes through the drying oven; the corona treatment device is arranged at the start end of the aluminum-coated paper, i.e., arranged in front of a first group of paper feeding rollers; and the aluminum-coated paper passes through the corona treatment device. Great surface tension is produced after an aluminum surface passes through the coating system, and high adhesion to various coatings is achieved, so that the problem that low-price coatings with poor adhesion cannot be applied to the aluminum-coated paper is solved, the adhesion of coatings with superior adhesion is enhanced greatly, and higher requirements can be met.


Soft robotic arms are designed to execute dexter-ous tasks safely in cluttered environments due to their inherent compliance and infinite degrees of freedom. Closed-loop control requires proprioceptive sensing to retrieve the spatial configu-ration of the robot. However, the integration of soft sensing in the soft continuum body is still an ongoing challenge. In this paper, we present a highly integrated pneumatically actuated soft robotic arm that consists of 1) an omnidirectional actuator design for multi-material 3D printing, 2) a modular approach with fast assembling connectors and 3) a tactile sensing array embedded in the joint of each module. The in-joint placement of the tactile sensing array is used to map the variation of stress distribution between the two connected modules and the posture of the actuator with learned k-nearest neighbors regression. The experimental results showed that the method estimated the posture of a three-segment soft arm with a mean error of 5.64 mm for the tip location.


5-Hydroxytryptamine(5-HT)is an important cerebral neurotransmitter.5-HT transporter(the serotonin transporter 5-HTT)gene polymorphism is involved in obstructive sleep apnea syndrome(OSAS).Reduction in cerebral 5-HT in animals can cause insomnia.5-HT can be also used for the treatment of insomnia.Cerebral 5-HT neuronal bodies are mainly located inside the raphe nuclei.Its head and tail affects the occurrence of different types of sleep,respectively.The different types of 5-HT receptor play different roles in sleep-wake cycle.Sleep studies of night shift workers and hibernating animals have shown that sleep and 5-HT gene polymorphism are associated.


Two novel C-linked oxadiazole carboxamide nucleosides 5-(2′-deoxy-3′,5′-β-D-erythro-pentofuranosyl)-1,2,4-oxadiazole-5-carboxamide (1) and 5-(2′-deoxy-3′,5′-β-D-erythro-pentofuranosyl)-1,2,4-oxadiazole-3-carboxamide (2) were successfully synthesized and characterized by X-ray crystallography. The crystallographic analysis shows that both unnatural nucleoside analogs 1 and 2 adapt the C2′-endo ("south") conformation. The orientation of the oxadiazole carboxamide nucleobase moiety was determined as anti (conformer A) and high anti (conformer B) in the case of the nucleoside analog 1 whereas the syn conformation is adapted by the unnatural nucleoside 2. Furthermore, nucleoside analogs 1 and 2 were converted with high efficiency to corresponding nucleoside triphosphates through the combination chemo-enzymatic approach. Oxadiazole carboxamide deoxyribonucleoside analogs represent valuable tools to study DNA polymerase recognition, fidelity of nucleotide incorporation, and extension. In honor and celebration of the life and career of John A. Montgomery.

Precise Point Positioning (PPP) technique, using single GPS receiver, has been used from several years especially in the static applications. Recently, there are many applications that rely on kinematic point positioning where the rover locations is determined using single GPS receiver in addition to the precise GPS satellite orbit and clock corrections that is developed and maintained by International Global Navigation Satellite System Service (IGS). In such environment, the GPS survey discrepancies should be addressed taken into consideration varying system dynamics, modeling algorithms, used software, receiver's types and other factors. This paper address the accuracy of GPS vehicle trajectory with high frequency data using kinematic point positioning technique and IGS data products. The study involves analyzing the kinematic GPS dual frequency carrier phase and pseudorange measurements utilizing the Real-Time Kinemtic LIB (RTKLIB) software and available data in a post processing mode. The receiver position utilizing point positioning technique has been verified and compared with the post processing relative kinematic trajectory solution. The PPP accuracy results using a low cost receiver were in the level of 10 cm for the horizontal components and 32 cm for the vertical component. The conclusions and further works are also included in the paper. Key words: GPS kinematic, precise Point positioning, IGS precise orbit and clock, RTKLIB, vehicle trajectory List of Symbols Pi the measured pseudorange on Li (m), fi the measured carrier phase on Li (m), r the true geometric range (m), c the speed of light, dt the receiver clock bias,


Five out of the ten tetraploid varieties of grapes produced at the Indian Agricultural Research Institute, New Delhi, came to fruiting. All of them matured earlier than their diploids. Detailed investigation in two of the varieties revealed that in the tetraploids, period II of the growth of berries was shortened, rates of period III growth were higher, TSS accumulated earlier and all the seeds were floating seeds (empty). It appeared that the late abortion of seeds resulting in empty seededness and earliness of maturity of bunch were associated with each other.


In this study we have developed a unique method for synthesizing very reactive water splitting materials that will remain stable at temperatures as high as 1450 °C to efficiently produce clean hydrogen from concentrated solar energy. The hydrogen production for a laboratory scale reactor using a "Thermo-mechanical Stabilized Porous Structure" (TSPS) is experimentally investigated for oxidation and thermal reduction temperatures of 1200 and 1450 °C, respectively. The stability and reactivity of a 10 g TSPS over many consecutive oxidation and thermal reduction cycles for different particle size ranges has been investigated. The novel thermo-mechanical stabilization exploits sintering and controls the geometry of the matrix of particles inside the structure in a favorable manner so that the chemical reactivity of the structure remains intact. The experimental results demonstrate that this structure yields peak hydrogen production rates of 1–2 cm3/(min.gFe3O4) during the oxidation step at 1200 °C and the 30 minute thermal reduction step at 1450 ° C without noticeable degradation over many consecutive cycles. The hydrogen production rate is one of the highest yet reported in the open literature for thermochemical looping processes using thermal reduction. This novel process has strong potential for developing an enabling technology for efficient and commercially viable solar fuel production.© 2013 ASME


In presenting a new instrument to theAmerican Medical Associationit becomes necessary to show that such an invention is needed to fill a want. It seems to me that heretofore we have not had an implement for the convenient removal of the opaque capsule, or so-called secondary cataract. Often on account of its flaccidity or toughness, the ordinary needling of the capsule will not clear the pupil. We are frequently obliged to open the eye and remove the capsule with the forceps. The knife that I herewith present is about the size of the smallest discission needle. It is curved about 50 degrees on both the edge and the flat, with both edges and point sharp. Its action is somewhat corkscrew-like. By a rotary motion of this knife one can tear the capsule into fragments if necessary, or draw it to the corneal margin and extract it. I have

Nowadays, the use of bisphosphonates is common. Bisphosphonates play an important role in the therapy and precaution of osteoporosis. The use of bisphosphonates may have concerned with cancer, especially oesophageal and gastric cancer. Nevertheless, whether bisphosphonates would cause oesophageal cancer have not been determined.


Isatins, derivatives of indole, represent important class of compounds belonging to nitrogen heterocycles. These compounds comprise synthetically vital substrates that are used as precursors for drug synthesis and raw materials for heterocycles etc. Research in this group of compounds has engrossed interest among scientific community in recent and past as Isatins are known to possess immense biological activities. Present work delineates synthesis, characterization, electrochemical and antimicrobial studies of four substituted derivatives of isatin derivatives. The cyclic voltammetric studies of all the analytes showed that four derivatives have better electro catalytic activity towards the analytes at glassy carbon electrode. These synthesized isatin derivatives were screened for their antimicrobial activity against Gram-negative bacteria (Escherichia coli and Staphylococcus aureus) and fungi such as Candida albicans and Penicillin chrysogenum, and found to possess considerable antimicrobial activity suggesting their effectiveness in developing antibiotics and novel drugs.


Nowadays, it is recognized the need for improved safety and efficacy protocols to evaluate the human stratum corneum (SC) and its interaction with topical and cosmetic formulations by minimally or non‐invasive methodologies. The aim of our research work was to streamline the HPLC‐TBARS‐EVSC (high‐performance liquid chromatography–thiobarbituric acid reactive substances–ex vivo stratum corneum) methodology, by exploring the results of a group of 18 subjects.


To determine whether parameters related to hydrography and phytoplankton utilization of nitrogenous nutrients are responsible for the variability in ratios of euphotic zone-integrated bac- terial production (BP) to primary production (PP), we measured bacterial production, primary pro- duction, new production, regenerated production and environmental variables in the euphotic zone in May 1995 and June 1996 at a frontal region in the Yellow Sea. The BP/PP ratios were highly vari- able with different hydrodynamic conditions, ranging from 0.03 for mixed waters to 0.40 for stratified waters. The BP/PP ratios were significantly correlated (r 2 = 0.64, p < 0.01) with water-column stabil- ity of the euphotic zone and, to a greater degree, with sea-surface temperature (SST; r 2 = 0.74, p < 0.001). SST was also closely correlated with water-column stability (r 2 = 0.91, p < 0.0001). An inverse relationship was found (r 2 = 0.61, p < 0.01) between BP/PP and ƒ-ratios, indicating close association of the variability of the BP/PP ratios with the relative utilization of nitrogen by phytoplankton. High BP/PP values were found when the euphotic zone was stratified and phytoplankton mostly depended on ammonium for nitrogen source, and low BP/PP values were found when the euphotic zone was completely mixed and phytoplankton mostly depended on nitrate. Our results suggest that both tur- bulent mixing and water temperature were underlying physical forces regulating variations in BP/PP ratios in the Yellow Sea. It might be possible to predict energy pathways in the Yellow Sea and, pre- sumably, in other marine environments by remote-sensing of SST and ocean color.


Proper selection of dielectric material is an important task for designing a patch antenna. In the present work, the variations in resonant frequency, bandwidth, |s 11 | (in dB) of a microstrip- fed rectangular patch antenna have been studied by varying the substrate thickness and its dielectric constant. I. Introduction With the development of modern wireless communications, there is an increasing demand for compact microstrip antennas. This is mostly due to their versatility in terms of possible geometries, light weight construction and suitability of integration with microwave integrated circuits that makes them applicable for many different situations. The basic antenna geometry comprises of a dielectric substrate sandwiched between the ground and radiating patch. The substrate, besides providing mechanical strength to the overall antenna design, also allows surface waves to propagate through it. Because the dimensions of the antenna are finite, the fields along the edges undergo fringing. The amount of fringing is a function of the antenna dimensions as well as the height of the substrate. Since waves travel both in air as well as in the substrate, so an effective dielectric constant (e eff ), given by (1) is introduced to account for the fringing effects (1).


Both environmental sustainability and the production of green products are strategies that are dictated by the need for environmental protection and modern business management practices, but still they are not widely applied. Adopting such strategies gives businesses the ability to operate more efficiently and develop a competitive advantage. This article proposes the theoretical development of a strategic framework using operations research models and business management tools aiming to develop a competitive advantage through sustainable environmental management.

Objective To explore the protective effect of angiotensin Ⅱtype 1(AT1) receptor blocker candesartan in hepatic fibrosis induced by carbon tetrachloride(CCL4) in rats and effects of candesartan on Ang-(1-7).Methods Except rats in control group,all were given intraperitoneal injections of 40% CCL4,and from the first day of the intraperitoneal injection,rats in treatment groups were given candesartan for 8 weeks by gastric gavage.Liver tissue and blood samples of all rats were examined at the end of 8 weeks.Histopathological study of liver tissue was done with hematoxylin-eosin(HE) and Masson trichrome staining.all rats were examined portal vein pressure.Blood samples were taken for detecting alanine aminotransferase(ALT) and the levels of Ang-(1-7)evaluated by ELASA.Results Compared with the health controls,candesartan significantly attenuated the degree of hepatic fibrosis and decreased portal vein pressure and plasma Ang-(1-7)levels increased.Conclusion Candesartan can retard the progression of hepatic fibrosis and exerts its antifibrogenic effect by adding Ang-(1-7)levels.


In the present paper we give an improvement of a previous result of the paper [M. M. Skriganov. Ergodic theory on $SL(n)$, diophantine approximations and anomalies in the lattice point problem. Inv. Math. 132(1), (1998), 1–72, Theorem 2.2] on logarithmically small errors in the lattice point problem for polyhedra. This improvement is based on an analysis of hidden symmetries of the problem generated by the Weyl group for $SL(n,\mathbb{B})$. Let $UP$ denote a rotation of a given compact polyhedron $P\subset\mathbb{B}^n$ by an orthogonal matrix $U\in SO(n)$, $tUP$ a dilation of $UP$ by a parameter $t>0$ and $N(tUP)$ the number of integer points $\gamma\in\mathbb{Z}^n$ which fall into the polyhedron $tUP$. We show that for almost all rotations $U$ (in the sense of the Haar measure on $SO(n)$) the following asymptotic formula \[ N(t\UP)=t^n{\rm vol} P+ O((\log t)^{n-1+\varepsilon}),\quad t\to\infty, \] holds with arbitrarily small $\varepsilon>0$.


Abstract We introduce an embedding of the Torelli group of a compact connected oriented surface with non-empty connected boundary into the completed Kauffman bracket skein algebra of the surface, which gives a new construction of the first Johnson homomorphism.


Large deep-seated landslides are widespread within the deeply incised landscapes formed in Tertiary soft rock terrain in New Zealand. The basal failure surfaces of deep-seated bedrock slope failures are commonly defined by thin, comparatively weak and laterally continuous bedding parallel layers. These layers have typically experienced some shear displacement at the time of slope failure. The key controls on the occurrence and form of deep-seated landslides are considered in terms of rock mass defect properties and tectonic and climatic forcing factors.

An 8-year-old boy with intractable left mesiofrontal lobe epilepsy underwent placement of stereotactic intracerebral depth electrodes to better localise the epileptogenic zone. Co-registration of preoperativeMRIand post-electrode implantationCAT allowed for anatomical localisation of electrode contacts. Electrical stimulation of electrodes over the dorsal and ventral banks of the cingulate cortex on the left produced right foot dorsiflexion and right wrist and elbow flexion, respectively, demonstrating detailed representation of cingulate motor function in humans, somatotopically distributed along the banks of the cingulate sulcus, as seen in the non-human primate.


Polarization-sensitive optical systems include those requiring very accurate irradiance measurements and those where polarization is the intended measurement. Low-polarization optical system design is the process of minimizing system polarization introduced by surface geometry, thin film coatings and birefringent elements, and measuring system components to verify polarization performance. The complicated, multi-step, iterative low polarization optical system design process requires initial system design, witness sample fabrication and measurement, reverse engineering of fabricated coatings and coating redesign, end-to-end system polarization aberration analysis, and system measurement and calibration. Most of this process will be spent iterating between design and measurement phases until a final design is reached that can be fabricated and calibrated to perform within the desired system tolerances. This work discusses low polarization optical system design using a three-mirror off-axis camera as an example.


Despite having difference in social and political systems, China and Pakistan have set up an example of bilateral friendship and cooperation for the last sixty years. In this regard, the recent China-Pakistan Economic Corridor is a milestone marking a new era of strategic and economic cooperation between the two 'all weather' friends. This paper explains how to design the layout of China-Pakistan Economic Corridor for promoting connectivity, deepening comprehensive strategic cooperation, formulating a long-term plan, and exploring the pragmatic cooperation in all areas.


An important step towards the eradication of HIV‐1 infection is deal with latent viral reservoirs. These reservoirs are long‐lived infected cells that replicate and produce virus and/or are infected cells located in sanctuary sites. Current models to investigate ex‐vivo tissue macrophages involve risky and invasive procedures. Decidual macrophages (DM) obtained from placental tissue represent a non‐invasive approach to study HIV‐1 pathogenesis. Macrophages are considering long‐lived cells that can harbor proviral DNA and establish an active viral reservoir. We hypothesize that DM represents an ex‐vivo model to study HIV‐1 active viral reservoir on patients with viral load under limit of detection. Six term placentas were collected from healthy women. After enzymatic digestion, DM were selected using CD14+ microbeads. Purified DM were infected with both CCR5 and CXCR4 tropic HIV‐1 virus for 72 hours after activation. Supernatant were collected every 24 hours and viral RNA was detected by sensitive RT‐PCR and active infection by p24 ELISA. Infected DM were harvested and DNA, RNA and protein were obtained. Copies of proviral DNA was determined by RT‐PCR using HIV‐1 gag gene primers. Host restriction factor SAMHD1 was quantified by western blot. CD4+ T‐cell line was used as a positive control. Results demonstrated that decidual macrophages can be infected and harbor the proviral DNA. These findings will be employed in HIV‐1 infected pregnant women under suppressive cART to demonstrate whether tissue macrophages are a true viral reservoir in HIV‐1 infection and transmission.


Wood frog Lithobates sylvaticus tadpoles develop in temporary wetlands where high population densities can force tadpoles into aggregations that intensify competition and can lead to cannibalism. However, chemical alarm cues released from injured conspecifics could also dissuade cannibalism. The purpose of this study was to test mechanisms that may influence can- nibalistic behaviour. We tested whether the tendency of tadpoles to consume conspecifics would increase with the presence of competition and/or cues of profitable diets. Tadpoles placed in 1L experimental containers were tested for feeding initiation times of multiple diets, including conspecific tissues and conspecific tissues combined with chemical cues from the alternative diets (brine shrimp and cornmeal). Tadpoles were tested in the presence and absence of a competitor, and at multiple times over the course of the study. Tadpoles exhibited an altered response to diets over time; however the presence of a competitor reduced re- sponse times to all diets including conspecific tissues. Similarly, the presence of specific diets also reduced the response time of tadpoles to conspecific tissues. These results suggest competition among feeding tadpoles could result in aggressive behaviour leading to indiscriminate predation and cannibalism (Current Zoology 60 (5): 571-580, 2014 ).


The human being is moved by feelings that contribute to interpersonal relationships in a positive and negative way. Prejudice, for example, is the result of ignorance that attaches to preconceived ideas, it can generate huge traumas, even suicide. In the school environment, as a reflection of society, there are several forms of prejudice. In this context, this article aims to present results of a survey on prejudice in a public school in the city of Montes Claros-Minas Gerais. To do so, he did bibliographic and field research, when a focus group occurred with the application of a questionnaire. The results obtained show that the majority of those surveyed have already suffered and or suffer some kind of prejudice.

Abilities of the psychotherapist according to supervisors: different approaching Several abilities are necessary to the practice of the psychologist especially in the clinical context. The aim of this study was to investigate the most and the least important abilities of the students as psychotherapists according to supervisors on the basis of different theories. Participated 10 supervisors from psychotherapy theories from client-centered psychotherapy (CCP), from psychoanalysis and from cognitive-behavioral therapy (CBT). The inventory was related to 17 abilities, and the supervisors were asked to organize them according to the importance of the ability. The CBT and the CCP supervisors emphasized eight abilities meanwhile the supervisors of the psychoanalysis emphasized 13 abilities. Psychoanalysis supervisors' group obtained more concordance. The least important ability by most of them was t "having scientific production". It was concluded that the inventory emphasized abilities which can guide the supervisors to obtain more objective assessment based on well delineated criterion.


The present paper deals with two species of the genus Ledermuelleria Oudemans,1923, of which one is a new species and the other is recorded for the first time from China.


Ion induced pressure instability is a potential problem for the ILC positron damping ring (DR) if the chosen pumping scheme does not provide sufficient pumping. The ion induced pressure instability effect results from ionisation of residual gas molecules by the beam particles, their acceleration in the field of the beam towards the vacuum chamber walls, causing ion induced gas desorption from vacuum chamber walls; these gas molecules in their turn can also be ionised, accelerated and cause further gas desorption. If the pumping is insufficient, this effect may cause a pressure instability, in which the pressure in the beam chamber grows rapidly to an unacceptable level. To analyse the ion induced pressure instability in the ILC positron DR the energy gained by ions was calculated for the appropriate beam parameters; it was found that the energy gain of ions will be about 300 eV. The ion induced gas desorption was estimated, and pumping solutions to avoid the ion induced pressure instability are suggested. The cheapest and most efficient solution is to use NEG coated vacuum chamber.


The steady state rate equations of transfer reactions catalysed by enzymes that follow the serine proteinase reaction mechanism in their hydrolysis reactions, have been solved and integrated. The integrated equations allow for calculations of maximal yields of product and of the time, tmax, at which that yield is present in a given reaction mixture. These important quantities have not been dealt with in previous theoretical studies of such systems.


This paper presents an automated procedure for designing reinforcement in D regions where plane sections do not remain plane after loading. The reinforcement is designed to resist stresses calculated in a non-linear finite-element analysis. The design procedure is implemented into NonOpt, which is a Fortran program that works in conjunction with the finite-element program DIANA. NonOpt gives three alternative methods for optimising the reinforcement design, of which strategy C is the subject of this paper. It finds the minimum weighted sum of the reinforcement ratios in two-dimensional structures such as deep beams subject to design constraints and practical requirements.


The application of two-dimensional J-resolved nuclear magnetic resonance spectroscopy to determine the structure of two bile metabolites isolated from rats injected interperitoneally with bromobenzene is described. The structures of the two molecules are obtained unambiguously from the proton-proton spin coupling constants. This paper discusses the fundamentals of the technique and demonstrates the resolution of small long-range coupling constants.


We present the results of ultrasonic pulse propagation experiments on dilute emulsions of resonant scatterers. Thanks to microfluidics, we achieved highly monodisperse oil-droplet dispersions embedded in a Bingham fluid. Underwater measurements allowed us to evidence up to about ten sharp Mie resonances, on both the acoustic attenuation and the phase velocity in the MHz range. These ultrasonic experiments are compared to theoretical predictions derived within the framework of the independent scattering approximation with an excellent quantitative agreement. The influence of the emulsion polydispersity is also investigated as well as the dependence of the acoustic properties on both size droplet and volume fraction in dilute regimes, for which the coupling between scatterers is negligible.


An electricity distribution system is a vital part of a total electric power supply system, since it is a link between a bulk transmission system and customers. It has been estimated that 80% of supply interruptions faced by customers are due to failures that occur in the distribution network. To secure more costumers with increasing competition, the energy supply companies are now increasingly under pressure to maintain a high degree of uninterrupted power supply quality and reliability. Therefore a practice of disconnecting all distributed generation units once a fault occurs is not a practical solution in a deregulated electricity market environment since it relies on power outage. Operation of safe intentional islanding would be viable solution. The aim of this paper is to present a genetic-based coordinated methodology for islanding operation and management of active and reactive powers in a distribution network after occurrence of a fault with regard to cost related to active and reactive powers generation of distributed generations, price of energy purchasing from a retail market, and loads interruption cost. Since optimal operation and islands configuration of a distribution network is a complicated and discrete problem, the genetic algorithm has been used for implementation and solving of the proposed algorithm. Simulations have been applied on 33-bus IEEE test system in three scenarios according to faulty branches and DGs penetration rate.

This proportion of females who get breast augmentation is rapidly expanding. Like a result, a radiologist's knowledge of the typical or aberrant radiological presentations of prevalent breast implants is critical. Mammography, Ultrasonography, or MRI are used to assess implant durability, identify disorders of the device as well as its accompanying capsules, and diagnose mammary diseases unconnected to implantation. Through its great accuracy or precision for identifying implant disintegration, magnetic resonance imaging of silicone breast augmentation is the best trustworthy method for determining prosthetic health. An ultimate goal of scanning breast implants, regardless of the computed tomography utilized, is to offer meaningful information regarding implantation viability, identify implantation malfunctions, or diagnose breast diseases unconnected to the augmentations, like cancers.


Hydraulic systems often contain discontinuous nonlinearity due to collision with moving parts. In numerical simulations, the points of discontinuity are usually located between two adjacent mesh points of time. Inappropriate treatment to detect the location can cause noticeable errors. In this paper, the authors propose an interpolation method to precisely detect and locate discontinuity due to collision. In this method, the mesh size between the time interval including the discontinuity is subdivided so as to equalize the truncation error of detection of discontinuous points with that of the main calculation scheme. The effectiveness of the method is tested by a simple system having an exact solution and a poppet valve system. The results are shown to be satisfactory.

Brain‐derived neurotrophic factor (BDNF) is involved in brain plasticity and neuronal survival during development. Less is known about the role of BDNF in the adult CNS. To explore the role of this neurotrophin, we have generated conditional mutants in which BDNF has been eliminated from the CNS after birth through the use of the cre‐loxP recombination system. We used BDNF(+/−) mice and wild‐type littermate mice to identify BDNF induced genes in brain cortex of BDNF (+/−) mice using microarray technology, whose expression is altered as a consequence of postnatal knockdown of BDNF. Messenger ribonucleic acid from the brain cortex of BDNF (+/−) and wild type mice were hybridized with microarray membranes. Interestingly, we found certain significant genes such as BDNF gene (2.5 decrease), calcium/calmodium‐dependent protein kinase II alpha (7.2 fold increase), potassium large conductance calcium‐activated channel (3.4 fold increase), GABA‐A receptor, subunit alpha 5 (2.2 fold increase), and acidic (leucine‐rich) nuclear phosphoprotein 32 family (7.1 fold increase). This study demonstrates an involvement of several genes in regulating BDNF function in the adult brain.


A ridge function is a function of several variables that is constant along certain directions in its domain. Using classical dimensional analysis, we show that many physical laws are ridge functions; this fact yields insight into the structure of physical laws and motivates further study into ridge functions and their properties. We also connect dimensional analysis to modern subspace-based techniques for dimension reduction, including active subspaces in deterministic approximation and sufficient dimension reduction in statistical regression.

Based on the weight functions of Ronsenfeld, an improved density functional theory was obtained by using the excess Helmholtz energy density from the Boublik-Mansoori-Canahan-Starling-Leland equation of state instead of that from the scaled particle theory. The obtained density functional theory was used to predict the radial distribution functions through the test-particle method for ternary hard-sphere mixtures with different diameters at various compositions. The calculated radial distribution functions are in excellent agreement with the computer simulation data available. The calculated results show that the test-particle method can be successfully used to predict the structure properties when the accurate density functional theory is adopted. The present work provides a method for investigating structural and thermodynamic properties of complex fluids by using the statistical mechanic theories. As an example, the molar volumes for the ternary system Ar+N2+CH4 were predicted by the Barker-Henderson perturbation theory using the radial distribution functions for hard sphere mixtures obtained in this work. The results were compared with the experimental values and good agreement was achieved.


The objective of this study is to use differential scanning calorimetry (DSC) to characterize the curing kinetics of Al2O3 and hydroxyapatite suspensions in acrylates. The heat evolution of the acrylate premix and ceramic suspensions in dynamic and isothermal curing was measured. The calculated activation energies for the acrylate premix and the two ceramic suspensions were 133, 74, and 78 kJ/mol, indicating a catalytic effect of the ceramic fillers. The curing behavior of the two ceramic suspensions modeled with the autocatalytic polymerization model with satisfactory results.


Objective To observe and evaluate the therapeutic effect of Benefit-Intelligence-Acupuncture Therapy (BIAT) on children suffering from mental retardation (MR). Methods The 100 patients were randomized into acupuncture group and control group,50 in each. The acupuncture group,in which the data of 37 patients was complete,was treated by BIAT,and the control group,in which the data of 36 patients was complete,treated by medicine. Both groups were treated for 3 treatment courses,4 weeksas one course. The comprehensive therapeutic effect of the two groups was compared to evaluate the influence of acupuncture on intelligence quotient (IQ) of MR patients. Results The total effective rate of acupuncture group amounts to 78.4%,better than 30.56% of the control group(P0.01). IQ of two groups was improved but the acupuncture group was better than the control group (P0.05). Conclusion BIAT can improve IQ of MR children with good clinical effect.


The invention discloses a vertical dust collector. The vertical dust collector comprises a handle part, a machine body part and a ground brush part which are sequentially connected. A dust bag is arranged in the machine body part. The ground brush part comprises a motor, a storage battery, a rolling brush, a worm wheel and a shell. A circuit board is arranged in the ground brush part and provided with a current detection module used for detecting the working current of the motor in real time, a current comparison module, a fault wait module, a power-off protection module, and a reset key module used for controlling the motor to normally work or stop working. The current value detected in real time is compared with normal working current and power-off protection current, corresponding control is executed, and therefore the motor can be effectively protected when the rolling brush abnormally works; in addition, even if the motor stops rotating due to winding of linear objects, the motor is restarted by pressing a key instead of being started by accident when operators clean away the linear objects, personal safety of the operators is ensured, the structure is reasonable, and control is reliable.


Well-defined block and graft copolymers of different types with different compositions and molecular weights, such as styrene(S)-2-vinylpyridine(P) diblock copolymers, SP star-shaped block copolymers, PSP triblock copolymers, styrene(S)-isoprene(1) multiblock copolymers of the (SI) n type, ISP triblock copolymers, SPP graft copolymers and their deuterated samples were prepared. Variations of the morphologies with compositions, molecular weight dependences of the lamellar domain sizes and conformations and distributions of block chains in the lamellar domains were studied in the strong segregation limit. Besides typical morphologies such as spherical, cylindrical and lamellar structures, ordered bi- and tri-continuous structures were found between cylindrical and lamellar structures for SP diblock copolymers, PSP and ISP tnblock copolymers, respectively. The composition ranges of morphologies arc different for the block and graft copolymers of different types. The molecular weight dependences of lamellar domain sizes are about the same, but their magnitude arc not always the same for the block and graft copolymers of different types. These results are well explained by the theories of Helfand-Wasserman and Semenov. Block chains in lamellae are extended along the direction perpendicular to lamellac, but they are contracted along the parallel direction. The former result is well explained by the theories, but the latter is not. Chains adjacent to the junction points between different block chains are localized near the domain interface, but chains at the free-ends of block chains are widely distributed in the domain with the maximum at the center of domain.


The complex dynamics that emerge from systems governed by deterministic chaos offer significant advantages to the neuromorphic engineer. Included in these is the potential for a very large memory store and the ease with which chaotic systems can be controlled. By definition, a chaotic system is a periodic. However, during the course of its trajectory through state space, the chaotic system will come infinitely close to points that it has previously visited. These almost repeating trajectories are referred to as Unstable Periodic Orbits (UPOs). Normally, under the influence of chaos, the trajectory would move away exponentially fast from its previous path, thereby describing a new path on the surface of the attractor. It is possible to apply a simple delayed feedback control mechanism to a chaotic system that will constrain it within one of its UPOs. This article presents a neural implementation of this delayed feedback mechanism. The network presented here is able to stabilize different UPOs in response to different input signals, with each UPO corresponding to a dynamic recognition state for that input. We also present two learning rules for this network, which enables it to adapt to novel inputs in a self-organized manner.
