Impedance spectroscopy is employed to probe the dielectric and electric transport mechanism in hierarchical flower like WO3 micro-structure. The electro-active regions defined from the impedance spectroscopy in the frequency range up 40Hz -110MHz explained by the existence of grains (bulk) and grain boundary phases in this hierarchical WO3 micro-structure. Modulation of impedance plane plots has been thrashed out due to the variation of relaxation-time with temperatures. An equivalent circuit model (RgbQgb) (RgQg) is employed to explain impedance plane plots. Overlapped large-polaron tunneling and correlated-barrier hopping transport mechanism is observed in the investigated temperature range. The detailed study of the electrical transport properties of WO3 shows that the impedance and allied parameters are strongly depending on temperature and its microstructure as well. The lower value of dielectric loss at 1MHz makes WO3, a potential material for high frequency application.


A brief commentary on the three papers presented in the session on 'industrial processes' is presented. In particular, emphasis is placed on the factors considered to be crucial for an industrial process, namely: catalyst activity, the selectivity of the overall catalysed reaction and the lifetime over which the performance is observed. Control of selectivity is viewed as being most important, and examples of how this is achieved through the use of membrane reactors and catalyst design are described.


The N-quinoline-2-carboxamido-8-aminoquinoline (QCA) was used as a suitable ion carrier in the construction of a Ho(III) PVC-based membrane sensor. This sensor demonstrated good selectivity and sensitivity towards the holmium ion for a broad variety of cations, including alkali, alkaline earth, transition and heavy metal ions. The proposed electrode exhibits a linear dynamic range between 1.0×10-6 and 1.0×10-2 M, with a near Nernstian slope of 20.4±0.3 mV per decade and a detection limit of 4.2×10-7 M. The best performance was obtained with a membrane composition of 30% poly(vinyl chloride), 56% nitrobenzene, 2% sodium tetraphenyl borate, 10% oleic acid and 2% QCA. The potentiometric response of the constructed electrode is pH independent in the range of 2.4-7.4. The sensor possesses the advantages of short conditioning time, fast response time (∼ 5 s) and especially, good selectivity towards transition and heavy metal and some mono, di and trivalent cations. The Ho3


Adhering to current HRI paradigms, all of the sensors, visualisation and legibility of actions and motions are borne by the robot or its working cell. This necessarily makes robots more complex or confines them into specialised, structured environments. We propose leveraging the state of the art of wearable technologies, such as augmented reality head mounted displays, smart watches, sensor tags and radio-frequency ranging, to "adapt" the human and reduce the requirements and complexity of robots.


Satisfaction among residents of institutions is an important issue. Several factors affect the elderly satisfaction as socio-demographic characteristics, health status, expectations about care, the structure, the process and the out come of the services. The present study aimed to assess the degree of satisfaction among elderly homes' residents in Alexandria. The sample included all elders living in the governmental homes in Alexandria who accepted to participate in the study. Data was collected using a structured interview sheet to obtain information about the general characteristics of the elderly, assessment of their functional abilities, and a consumer satisfaction tool which was translated and tested for content validity and reliability. The results revealed that the majority of the residents were either satisfied or very satisfied with the total satisfaction score of all satisfaction's domains (48.9%, 43.1% respectively), while only 8.1% of the elderly were dissatisfied. Recommendation: Regular monitoring and evaluation of services provided at the elderly homes to ensure a best quality of care at them. INTRODUCTION: Life expectancy had risen sharply during the twentieth century and is expected to continue to rise, in virtually all populations throughout the world, where the population over 65 years increases by 2.5% per year. In the developed countries, 12.6% of the populations are elders compared to only 4.6% in the developing ones.(1,2) In Egypt, the percentage of those aged 60 years and over represent 5.8% of the total population and is expected to reach more than 10% by the year 2025.(3) The percentage of elders living in institutions dramatically increases with age.(4) In USA , the percentage of persons aged 65 years or older living in institutions 207 Bull High Inst Public Health Vol.39 No.1 [2009] represent 5%, while in UK it represents 6.3%.(5,6) On the other hand, this percentage reaches 1% in Egypt, 1.4% in United Arab Emirates, and 1.3% in Bahrain.(7-9) In Alexandria, the rate of institutionalization was estimated to reach 0.2 per 1000 elderly persons 60 years of age or older.(10) Institutions provide the elders with a shelter, assistance with activities of daily living, meal and house keeping services. They also provide care for the disabled, occupational and physical therapy, in addition to social and psychological support.(11) In spite of these services, there are some shortcomings of these homes. They may increase the family separation, increase dependency of the elders, and may dehumanize the elders by destroying their defined role in the family and community thus they lose their sense of identity and security.(12) One of the main aims of the institutions is meeting the needs and expectations of the consumer. The role of the client in the health care and social services system is evolving, "patients/clients" became consumers and are now often referred to as "consumers". The emphasis on the consumer's perspective has created a demand for information on consumer experiences and satisfaction with health and social services.(11) This evolution towards consumer focus has also increased the importance of measuring satisfaction with care for older adults.(13) Patient satisfaction is a primary outcome that may be defined as the extent to which an individual's needs and wants are met.(14) Elderly satisfaction is the degree of congruency between consumer's expectations of ideal care and the perception of real care he or she receives. Satisfaction results from meeting or exceeding consumer's expectations. Patient satisfaction is an important consideration that is closely related to consumer care efficiency. Measuring consumer satisfaction can provide useful


The concept of primary magmas presupposes that a magma may be conveyed directly from the mantle to the surface of the earth. The temperature relations for a primary magma ascending through a dyke are calculated. The results suggest that the required ascent velocity of 1–10 cm/sec prohibits gravitative differentiation as well as wall rock assimilation. The nodule-bearing alkaline magmas therefore represent unmodified mantle-derived magmas. The hydrostatic overpressure of the primary magmas is relatively high, of the order of a few kilobars.

THREE ESSAYS IN LABOR ECONOMICS by Benjamin Van Kammen The University of Wisconsin-Milwaukee, 2013 Under the Supervision of Professors Scott J. Adams and Scott Drewianka There are three chapters in this dissertation, each of which consists of a journal-length article. They are on the following subjects. The first chapter uses ordinances in San Francisco and Washington, D.C. to measure the effects of mandated paid sick leave on employment and wages. Using the Quarterly Census of Employment and Wages, an employment increase is observed in San Francisco and Washington, D.C. relative to places without an ordinance. This evidence suggests that sick leave mandates correct a market failure of under-provision of benefits. The second chapter uses a novel measure of distance based on the O*Net Content Model to show that information revealed by the spouses' occupations predicts divorce. Spouses that are closer in terms of their occupations' requisite knowledge are more likely to divorce, supporting the hypothesis that gains from specialization in a household renders a marriage more durable. Dissimilar spouses in terms of their occupations' activities are more likely to divorce, suggesting that each spouse brings an inclination toward certain activities to the marriage that reflects compatible preferences for joint consumption of household public goods.


Policing, even stop and account, despite being tied to the local, has been confronted with the current pervasiveness of global interconnectedness. The complicated interaction between the global and local in the field of policing, however, is always the result of political and cultural assumptions in each society. This article firstly offers a brief description of recent Japanese policy and practice of police stop and account as part of a 'War on Illegal Immigrants'. While reflecting on the global trend of criminalisation of immigration, it then explains political and cultural implications which have brought about this extraordinary policy and practice in the context of modern Japanese society. It concludes that recent development of Japanese police stop and account policy and practice can be best understood as the site for interaction between the national narratives in relation to crime and ethnicity, and the corresponding apparatus of globalisation.


Provided are an apparatus and a control method. At a timing after a target application is installed, in a case where a usage amount of a resource used at a predetermined timing by the target application exceeds a declaration of a maximum value of the usage amount of the resource described in an application file corresponding to the target application, a framework is instructed to stop the target application.


We have fabricated and measured ballistic graphene transistors with two oblique gates that can be independently biased. The gate lengths are about 38 nm and are separated by a distance of 30 nm, the tilting angle being of 45o with respect to source and drain electrodes distanced at 190 nm. Electric measurements reveal specific properties of ballistic carrier transport, i.e. nonlinear drain voltage-drain current dependence, showing a saturation region, and negative differential resistance at certain bias voltages, which cannot be explained without physical mechanisms related to ballistic transport. Tens of ballistic transistors, with very large transconductances, were fabricated on a chip cut from a 4 inch graphene wafer. Such double-gate transistor configurations can be used also as extremely efficient, state-of-the-art photodetectors.


We have fabricated highly efficient organic light-emitting diodes (LEDS) using in situ thermally polymerized hole transporting materials containing triphenylamine/tetraphenyldiaminobiphenyl as side chains. Double-layer LEDs made with these thermally polymerized polymers as the hole transporting layer and tris(8-hydroxyquinoline) aluminum as the emitting layer showed comparable brightness but lower turn-on voltages and better quantum efficiencies than the device made with the conventional hole transporting molecule, N-N′-diphenyl-N,N′-bis(3-methylphenyl)(1,1′-biphenyl)-4,4′-diamine.


siasme, and others into deism. In the light of this diversity, their involvement in religious and political controversy both in France and in the host countries is extensively explored; and the work concludes on an examination of certain works that addressed broader sociopolitical issues, such as the status of women (Poulain de la Barre), equality of wealth and opportunity (Gueudeville), and educational reform (Maubert de Gouvest). Many of the names of those discussed are, and are likely to remain, unfamiliar. The major exception is the Abbé Prévost, whose confessional vacillations are helpfully tied into the chronology of his novelistic output. Overall this is an impressive piece of scholarship, not least because the reader is reassured to discover that the question mark of the title is reflected throughout in Boisson's open-minded approach to his material.


Jackson and Jacobs (1983) reopened a debate, already long resolved by statisticians and linguists, that dealt with treating language variables as random versus fixed effects in analysis of variance designs. Jackson and Jacobs extended the argument to suggest that designs were invalid unless they included multiple messages within single experiments. An ensuing debate has filled scarce journal space, often advancing specious arguments, but at times offering sensible alternatives to the position that there is an invariant messages‐as‐fixed‐effect fallacy in our literature. Despite the lengthy debate, there has been no empirical scrutiny of relevant claims. Presented here is the first empirical test of three alternative analytic models using data from a carefully controlled experiment.


The Raman interaction of a pair of two-level atoms with the radiation field is studied. The emission spectra for two interacting processes are calculated in which either two atoms couple to the field with different constants or with the same constant but at the same time the dipole-dipole interaction between two atoms being included in the consideration. The effect of the relative value of two atom-field coupling constants and also that of atomic dipole-dipo-le interaction on the emission spectra are analyzed.


Latent semantic analysis (LSA) is a method for information retrieval and processing which is based upon the singular value decomposition. It has a geometric interpretation in which objects (e.g. documents and keywords) are placed in a low-dimensional geometric space. In this paper, we derive an alternative algebraic/geometric method for placing objects in space to facilitate information analysis. We show that our method is closely related to LSA, and essentially equivalent for particular choices of scaling parameters. We then show that our approach supports a number of generalizations and extensions that existing LSA approaches cannot handle.


Foreign Direct Investment and Domestic Investment provide a crucial basis for economic development of any country. This study examines the causes and impacts of Real Gross Domestic Product (RGDP), Real Domestic Investment (DI) and Real Foreign Direct Investment (FDI) in Sudan for the period from 1990 to 2011.The importance of this study stems from the vital role of investment (domestic and foreign) in the development process through enhancing economic growth, improving infrastructure and achieving welfare. This study adopted Vector Autoregressive Model and Granger Causality Test (1969). The study depended on secondary data collected from Central Bank of Sudan and Central Bureau of Statistics. Our empirical evidence suggests that the causality directions running positively in the period (1990-2011). There is unidirectional causality of Foreign Direct Investment (FDI) to Real Gross Domestic Product (RGDP), from Real Gross Domestic Product (RGDP) to Foreign Direct Investment (FDI), from Domestic Investment (DI) to Real Gross Domestic Product (RGDP), from real gross domestic product (RGDP) to domestic investment (DI), from foreign direct investment (FDI) to domestic investment (DI), and from domestic investment (DI) to foreign direct investment (FDI). Granger causality results show that there are no statistically significant implications of the independence causality relationship between Domestic Investment( DI) and Real Gross Domestic Product (RGDP), Real Gross Domestic Product(RGDP) to Domestic Investment( DI), Foreign Direct Investment (FDI) ) to Real Gross Domestic Product (RGDP), Real Gross Domestic Product (RGDP) to Foreign Direct Investment (FDI), Foreign Direct Investment (FDI) ) to Domestic Investment(DI), and Domestic Investment ( DI) to Foreign Direct Investment(FDI). The VAR estimation shows that the coefficients of lagged RGDP significant in the regression of the RGDP, the coefficients of lagged DI significant in the regression of the DI and FDI, the coefficients of lagged DI insignificant in the regression of the RGDP, and the coefficients of lagged FDI insignificant in the regression of the RGDP.The study recommends raising more real financial resources for the purpose of investing in economic and social infrastructure as well as in oil exploration. Industrialization is highly recommended for import substitution purpose and for increasing the value added for Sudan's exports to benefit more from international trade. These require encouraging domestic saving, attraction of foreign funds to supplement the domestic component, strengthening foreign relations, and facilitating the investment procedures and thus achieving economic growth in the country.


Alain Epp Weaver's analysis of the theological foundations of Augustine's proscription of all lies in all circumstances does more than improve our understanding of Augustine. In drawing a plausible and illuminating parallel between the theological logic of Augustine and the theological logic of John Howard Yoder, Weaver not only succeeds in defining the credibility of Christian pacifism but also provides support for interpreting Yoder as a biblical realist. Moreover, the divergence between Weaver and Christopher Kirwan in their critical assessments of the cogency of Augustine'streatment of lying serves to throw into relief the differences between secular philosophical ethics and theological ethics, incidentally suggesting why it is often difficult for twentieth-century thinkers to understand and evaluate premodern texts.


Supplemental digital content is available in the text. Importance Obesity may be a modifiable risk factor for pelvic floor disorders. Objectives The objective of this study is to determine associations between weight, weight changes, and cumulative exposure to excess body mass index (BMI) from prepregnancy to 1 year postpartum on pelvic floor support and symptoms 1 year after first vaginal birth. Study Design In 645 primiparous women who gave birth vaginally, we assessed anatomic pelvic floor support, pelvic floor symptoms and BMI at the third trimester, 5 – 10 weeks, and 1 year postpartum; we also assessed BMI prepregnancy and predelivery. Using multivariable models, we determined associations between pelvic floor outcomes 1 year postpartum and BMI quartiles at different timepoints, gestational weight gain, and postpartum weight retention. We evaluated associations between stress urinary incontinence (SUI) and moderate/severe urinary incontinence (UI) 1 year postpartum and cumulative excess BMI from prepregnancy to 1-year postpartum (BMI1year). Results Body mass index was not associated with anatomic support, composite symptom burden, overactive bladder, anal incontinence, or constipation at any timepoint. Gestational weight gain and postpartum weight retention were not associated with any 1-year outcome. Body mass index at every timepoint was positively associated with SUI and moderate/severe UI; BMI1year was most predictive. Cumulative excess BMI was positively associated with SUI and moderate/severe UI but only slightly more predictive of these outcomes than BMI1year alone. Conclusions Body mass index over the pregnancy trajectory was not associated with outcomes other than UI. The small advantage of cumulative exposure to excess BMI over BMI1year in predicting SUI and moderate/severe UI suggests that BMI1year adequately captures risk of these 1-year outcomes.

Teachers' self-efficacy, namely teachers' beliefs in their ability to effectively handle the tasks, obligations, and challenges related to their professional activity, plays a key role in influencing important outcomes in students and well-being in the working environment. The purpose of this study was to examine the effect of social support on teachers' teaching efficacy about play, and to investigate whether ideation plays a mediating role for teachers in early childhood education. For this purpose, SEM structural model analysis was conducted based on the data of 622 early childhood teachers in Seoul, Gyeonggi province and Incheon, Korea. The results of this study are as follows. First, social support for early childhood teachers had a positive effect on ideation and teachers' teaching efficacy about play. and ideation also had a positive effect on teachers' teaching efficacy about play. Second, ideation was found to mediate the relationship between social support and teaching efficacy about play for early childhood teachers. As a result, ideation was influenced by the sociocultural environment to which the teacher belongs, and that teachers who receive positive social support demonstrate effective strategies for play and learning through ideas. This study presents implications for the socio-cultural impact of social support for early childhood teachers on individual teachers and the educational field.


The present invention provides a film comprising a zinc oxide (103) plane having a X- ray diffraction peak of zinc oxide crystal, a photoelectric conversion element having the zinc oxide thin film, and methods for their production. By these methods, the crystal structure of the zinc oxide thin film is increased, and provides excellent short-circuit current density (Jsc) of the photoelectric conversion element.


In this paper we use ACL2 to formally verify the correctness of an algorithm used in the analysis of dynamical systems. The algorithm uses interval arithmetic to check that a given vector field is transverse (non-tangential) to an edge (line segment). Instead of operating on numbers, interval operations operate on intervals, and they are guaranteed to return an over-approximation of the actual answer, thereby allowing us to use floating point arithmetic in a safe way. In this paper we prove that if the algorithm identifies an edge as transverse, then it is in fact transverse, as long as the underlying interval arithmetic operations are correctly implemented.


Many researchers have proposed hybridization of fuel cell powerplants for unmanned aerial vehicles with the goal of improving the aircraft performance. The mechanisms of this performance improvement are not well understood. This work poses the problem of deriving energy management strategies for fuel cell powered, hybrid fuel cell powered and internal combustion powered aircraft as an optimal control problem. Dynamic programming and sequential quadratic programming are used with reduced order dynamic models to solve for optimal energy management strategies and optimal flight paths for these aircraft. Results show that hybridization and flight path management does not improve the endurance of fuel cell powered aircraft for a fixed airframe design, as it can for internal combustion powered aircraft. During the aircraft design process, hybridization does allow the aircraft power constraints to be decoupled from the aircraft energy requirements, with beneficial results in an integrated aircraft design process.

During the Spring 2004 semester, the District Office of Institutional Research collaborated with the College Research Offices to conduct the Noel-Levitz Student Satisfaction Inventory, the third administration of this student satisfaction survey since 1998. What follows is an analytical report designed to summarize the results by key areas of most importance to students, with a discussion of important items within each area, for each Los Rios college -American River, Cosumnes River, Folsom Lake and Sacramento City. The results of this study are a first step in defining possible areas of concern to students. Although surveys are useful in identifying possible concerns, they do not identify why issues are of concern. This survey's use becomes more relevant as the results are used in the context of other studies that have been conducted, as well as with follow-up college level focus groups to be scheduled in the Fall that will provide more in depth understanding of identified concerns to use for organizational and planning purposes by each college. Although key observations are summarized below, readers are encouraged to read the full report and review the accompanying data tables that summarize all student responses, in order to understand items of importance to students of each individual college. The key observations from analysis of survey results include:


Intracranial tumor is one of the most common diseases in nervous system, which has great harm to the function of human nervous system. Surgical tumor resection is the primary treatment method for the disease. Ultrasonoscopy is helpful for lesion localization and boundary determination in intracranial tumor resection surgery resection rate improvement and reduction of postoperative tumor recurrence probability. However, the deficiency of routine ultrasound examination in image contrast leads to obvious limitation thereof in clinical application. The blood perfusion difference between pathological tissue and normal tissue can be utilized to increase the image contrast in ultrasound contrast, thereby providing more accurate and clearer ultrasonic image, assisting the performer to determine tumor boundary more accurately, understand the hemoperfusion status of tumor, judge residual tumor, and improving diagnosis accuracy and surgical resection rate. 1.

Automatic Plate Number Recognition (APNR) has important applications in traffic surveillance, toll booth, protected parking lot, No parking zone, etc. It is a challenging problem, especially when the license plates have varying sizes, the number of lines, fonts, background diversity etc. This work aims to address APNR using deep learning method for real-time traffic images. We first extract license plate candidates from each frame using edge information and geometrical properties, ensuring high recall using one class SVM. The verified candidates are used for NP recognition purpose along with a spatial transformer network (STN) for character recognition. Our system is evaluated on several traffic images with vehicles having different license plate formats in terms of tilt, distances, colors, illumination, character size, thickness etc. Also, the background was very challenging. Results demonstrate robustness to such variations and impressive performance in both the localization and recognition.


In this paper we propose a methodology to set prices of perishable items in the context of a retail chain with coordinated prices among its stores and compare its performance with actual practice in a real case study. We formulate a stochastic dynamic programming problem and develop heuristic solutions that approximate optimal solutions satisfactorily. To compare this methodology with current practices in the industry, we conducted two sets of experiments using the expertise of a product manager of a large retail company in Chile. In the first case, we contrast the performance of the proposed methodology with the revenues obtained during the 1995 autumn-winter season. In the second case, we compare it with the performance of the experienced product manager in a "simulation-game" setting. In both cases, our methodology provides significantly better results than those obtained by current practices.


To study the feasibility of the production of automobile steel of medium-manganese TRIP steel with the continuous annealing process,the effect of different manganese content on microstructure and mechanical properties of medium-manganese TRIP steel was investigated on heat treatment system for thin steel sheet CCT-AY-Ⅱ type. The microstructure of the steel with different Mn content was observed by means of SEM,TEM and EBSD. The amount of retained austenite in the steel was determined by X-ray diffraction analysis and its mechanical properties were measured in the laboratory. When the steel is at 650 ℃ for 3 min,and with the increase of manganese content,the yield strength first increases and then decreases,the tensile strength continuously rises,while the elongation almost maintains at about 20%. Research on the microstructure shows that the retained austenite increases with the increasing of Mn content. When Mn content is more than 6%( including 6%),the real stress-strain curves appears jagged due to the dynamic strain aging,and the work hardening exponent is far greater than that of the 5Mn steel. TRIP effect of metastable austenite and ultrafine ferrite and martensite together provide high plasticity.

The use of guava (Psidium guajava l.) extract on preventing lipid oxidation in chicken meat ALUNO: Samara Aquino Amador ORIENTADOR: Dra. Aline Mondini Calil Racanicci 1 – Universidade de Brasília UNB Two experiments were conducted to evaluate the antioxidant capacity of guava residue extract in preserving pre-cooked chicken breast and thigh meat balls during chilled and frozen storage. The extract was composed of the dried residue containing pulp, seeds and skin of guava was and analyzed for DPPH and total phenolics in different solvents for extraction. For each experiment fresh chicken meat was purchased in local supermarket in Brasilia/DF, and used to prepare pre-cooked meatballs with the following treatments: CONT: without antioxidants; BHT: addition of 0.2% of the synthetic antioxidant BHT; 0.5EG: addition of 0.5% of guava extract (EG); 1,0EG: addition of 1.0% of EG; 1,5EG: addition of 1.5% of EG. The samples were stored in a complete randomized design in –chilled (4 ° C) for 8 days and frozen (-12 ° C) storage for 4 months, and analyzed in duplicate periodically for TBARS (Thiobarbituric acid reactive substances). The results were analyzed using the Tukey test with 5% significance and linear regression analysis between treatments with EG using the Mixed SAS Enterprise Guide 5.1 (SAS Inc, Cary, NC, USA). The EG showed higher (p<0.05) values extracted in water: 52.22 mg GAE/g, 80.43% of antioxidant activity and 81.33% of inhibition. In experiment 1 using chicken breast meat balls, all treatments preserved (p<0.05) lipids from oxidation, when compared to CONT during chilled and frozen storage. TBARS results were lower (p<0.05) compared to BHT, however, 1.5EG was the most effective treatment. As increased EG addition to meat products, a significant (p<0.05) reduction in TBARS values was seen and reflected in significant (p<0.05) negative regression that resulted in 1.62% and 1.81% EG for minimal TBARS production during chilled and frozen storage, respectively Experiment 2 showed a positive and significant (p<0.05) effect of the antioxidants in general on the lipid stability, compared to CONT , however, 1.0%EG and 1.5% EG reduced (p<0.05)

Modern Arab culture retains many living elements adopted from ancient, now extinct cultures. Using the example of the traditional musical instrument rabab, the connection of modern culture with the cultures of the distant past (starting from the Sumero-Akkadian period of Mesopotamia), as well as with other aspects of the traditional way of life, is shown. The relationship between the emotional and acoustic specifics of the sound of the rabab and the features of a traditional residential building in the Levant region, which are in demand in modern energy-saving housing construction, is shown.


In the foregoing chapters there have been presented certain problems, some selected practices, and a statement of a theory relating to safety education. Fur thermore , this new claimant for school at tention has been considered a subject of instruction which is immediately related to industry, to transportat ion, to the home, and to the school. I t has also been viewed in its broader aspect as a new human emphasis in industr ial and social relations. Safety education has been clearly shown by striking arrays of facts to be a par t of the job of keeping physically alive, as well as being associated with the general problem of living together well in organized society. .The purpose of this chapter is to make a brief summary of what has preceded and to suggest fu ture problems. In an earlier chapter it was pointed out that a condition of safety with respect to any people grows out of their habits of living or of acting at any given time. For example, in a primitive society, even in a nomadic state and later among peoples with simple industrial interests, or even in modern times in a distinctively rura l community, hazards exist against which precautions have to be taken if life itself is to be preserv.ed, personal in ju ry avoided, and social purposes realized. Educat ion in safety is the education which leads to the avoidance of accident in the face of such hazards. As the social and economic s tructure became more complex, and high speed and complicated machinery came into use, new dangers accompanied this development, and systematic instruction in industrial safety followed. Safety organizations in industr ial plants began to ,appear in 1905 and grew rapidly in number. I t was evident that society was gradually becoming more sensitized to considerations of human and of individual worth as contrasted with considerations of material gain. The reduction of human losses following the movement for organized industrial safety, the increase in production, as well as the better working relations between employee and employer which safety considerations have provided,

An investigation was made of the nutritional status of the cultivation bases of sisal hemp (Agave sisalana) in Zhanjiang of China's Guangdong province and the data was treated statistically to analyze the relationship among the nutrient elements and between nutrients and economic traits of the plants. Application of N, P or Zn to the sisal hemp field significantly or highly significantly increased blade yield, leaf fiber weight, leaf weight and fiber yield. Ca or Si application significantly raised leaf weight but significant reduced fiber rate. K dressing significantly decreased fiber weight.


Abstract The development, survivorship, longevity, reproduction, and life table parameters of the spirea aphid, Aphis spiraecola Patch, were evaluated at 25°C on seven commonly grown plants (Polyscias crispata (Bull) Merrill cultivar chicken-gizzard aralia, P. scutellaria (Burman) Fosberg, Vibernum suspensum Lindley, grapefruit (Citrus paradisi Macfadyen), rough lemon (C. jambhiri Lushington), pineapple orange [C. sinensis (L.) Osbeck variety pineapple orange], orange jessamine [Murraya paniculata (L.) Jack]) in the laboratory. Spirea aphid failed to survive on orange jessamine. The developmental times for the immature stages ranged from 7.9 d on P. scutellaria to 9.9 d on grapefruit or pineapple orange. The immature survival varied from 92.7% on P. scutellaria to 78.8% on pineapple orange. The average number of nymphs reproduced per female were 42.7, 35.7, 28.7, 22.3, 18.0, and 11.7 on P. crispata, P. scutellaria, V. suspensum, grapefruit, rough lemon, and pineapple orange, respectively. Female adults lived an average of 14.1, 15.3, 12.2, 11.0, 12.0, and 9.3 d on these same hosts. The intrinsic rate of increase (rm) for spirea aphid on P. crispata was highest. Jackknife estimates of rm varied from 0.308 on P. crispata to 0.177 on pineapple orange. The mean population generation time on these hosts ranged from 11.6 to 13.2 d. It was concluded that the ability of spirea aphid to feed and develop on a wide range of host plants increases its chance to infest citrus and thereby spreading the citrus tristeza virus.


Michael Gow's celebrated play Away (1986) commences with a tatty school version of Shakespeare's A Midsummer Night's Dream. Set in the era of anti-Vietnam War protests, Away ironically salutes the iconic performance traditions of the 'romantic' Dream. At the Prince's Theatre, Manchester, in 1901–02, actor-manager Robert Courtneidge directed elaborate productions of this play and As You Like It, and under the management of George Musgrove toured them to Australia, where Twelfth Night was added. These productions' ensemble casting was central to Courtneidge's and Musgrove's ambitions for addressing the 'distinctive geographies' of regional taste.

This study set out to examine the issues and challenges on the non-publication and circulation of taxation rulings in The Gambia. In addition, this paper presents the rationale of making and publishing a Commissioner General's rulings on the application and interpretation of certain provisions on the tax laws where there is ambiguity in order to avoid distortions and differing inconsistent applicable views of persons. In this paper, the author provides a holistic demystification on the ontology of taxation rulings within the context of The Gambia's laws of taxation, citing the Gambia Revenue Authority as an example. The study however, indicates that no previous study of this nature has ever been commissioned in The Gambia, thus catapulting the need to conduct such study to add to the body of knowledge by limiting the dearth of literature in the discourse of public finance and in order to examine the mechanism of taxation rulings in terms of making provisions to prepare tax rulings, reproduce them in adequate numbers, distribute them to officials and made them available to the general taxpayers. On a simpler note, this study discusses on the need for objective clarifications and better codification on the provisions of the existing tax laws, policies and regulations within the operational and administrative parameters of taxation. In summary, the paper indicates that a public ruling is still yet to be conventionally made available to the tax officials and the taxpayers. Finally, the results of this study should be of interest to taxing authority as it concludes with some prescriptive recommendations and solutions identified as the essential mechanics and alternative paradigms towards having in place a robust, mutually-inclusive, well-established and functional tax ruling mechanism.

A proposal has been made to establish a high density global network of atmospheric micro transponders to record time, temperature, and wind data with time resolution of {le} 1 minute, temperature accuracy of {+-} 1 K, spatial resolution no poorer than {approx}3km horizontally and {approx}0.1km vertically, and 2-D speed accuracy of {le} 1m/s. This data will be used in conjunction with advanced numerical weather prediction models to provide increases in the reliability of long range weather forecasts. Major advances in data collection technology will be required to provide the proposed high-resolution data collection network. Systems studies must be undertaken to determine insertion requirements, spacing, and evolution of the transponder ensemble, which will be used to collect the data. Numerical models which provide realistic global weather pattern simulations must be utilized in order to perform these studies. A global circulation model with a 3{sup o} horizontal resolution has been used for initial simulations of the generation and evolution of transponder distributions. These studies indicate that reasonable global coverage of transponders can be achieved by a launch scenario consisting of the sequential launch of transponders at specified heights from a globally distributed set of launch sites.


A social service agency in a small city on the American high plains tried to meet the needs of Vietnamese and Hispanic newcomers. Drawing on several years of practice in the agency, this article documents the nature of relations between established resident agency workers and their newcomer clients. New immigrant needs and cultural values are not always understood by agency workers or reflected in office policy, but the agency tried to serve newcomers nonetheless. The office's refugee program is an example. The article presents the organizational conditions that seem to facilitate equitable service delivery to newcomers, and comments on the role of the practicing anthropologist in complex organizations.


Simple Summary Primary immunodeficiencies (PIDs) and secondary immunodeficiencies (SIDs) weaken the immune system, making people prone to infections and possibly affecting cancer development. Epstein–Barr virus (EBV), a common virus, is linked to cancer, especially in those with weak immunity. This study compares immune factors like PD-1/PD-L1, CTLA-4/CD86, CD200R/CD200, and EBV in chronic lymphocytic leukemia (CLL, a SID) and common variable immunodeficiency (CVID, a PID). We studied CLL, CVID, and healthy people, checking EBV activity and immune checkpoints. Both CLL and CVID patients showed more EBV activity, and their immune checkpoints were changed, possibly affecting EBV and immunity. This study shows how immune issues, EBV, and checkpoints might contribute to cancer in people with weakened immunity. It suggests ways to manage these risks. More research is needed to understand this fully and develop treatments. Abstract Primary immunodeficiencies (PIDs) and secondary immunodeficiencies (SIDs) are characterized by compromised immune function, rendering individuals susceptible to infections and potentially influencing cancer development. Epstein–Barr virus (EBV), a widespread herpesvirus, has been linked to cancer, particularly in those with weakened immune systems. This study aims to compare selected immune parameters, focusing on immune checkpoint molecules (PD-1/PD-L1, CTLA-4/CD86, CD200R/CD200), and EBV reactivation in patients with chronic lymphocytic leukemia (CLL, a representative of SIDs) and common variable immunodeficiency (CVID, a representative of PIDs). We performed a correlation analysis involving patients diagnosed with CLL, CVID, and a healthy control group. EBV reactivation was assessed using specific antibody serology and viral load quantification. Peripheral blood morphology, biochemistry, and immunophenotyping were performed, with emphasis on T and B lymphocytes expressing immune checkpoints and their serum concentrations. Our findings revealed elevated EBV reactivation markers in both CLL and CVID patients compared with healthy controls, indicating increased viral activity in immunodeficient individuals. Furthermore, immune checkpoint expression analysis demonstrated significantly altered percentages of T and B lymphocytes expressing PD-1/PD-L1, CTLA-4/CD86, and CD200R/CD200 in CLL and CVID patients. This suggests a potential interplay between immune checkpoint dysregulation and EBV reactivation in the context of immunodeficiency. In conclusion, our study underscores the intricate relationship between immune dysfunction, EBV reactivation, and immune checkpoint modulation in the context of immunodeficiency-associated cancers. The altered expression of immune checkpoints, along with heightened EBV reactivation, suggests a potential mechanism for immune evasion and tumor progression. These findings provide insights into the complex interactions that contribute to cancer development in immunocompromised individuals, shedding light on potential therapeutic targets for improved management and treatment outcomes. Further investigations are warranted to elucidate the underlying mechanisms and to explore potential interventions to mitigate cancer risk in these patient populations.


Mercury together with other trace elements were analysed in stream and overbank sediments of low- to medium-order drainage basins from Žumberak and Samoborsko Gorje region. The mean regional geochemical background level for mercury concentration in stream sediments and overbank sediments is 40 ng/g and 62, 5 ng/g, respectively. The extreme mercury concentration values are estimated in stream and overbank samples of Rudarska Gradna catchment. The analyses of the samples from the overbank profiles in this catchment show large vertical and lateral variations in chemical composition. The high concentrations of Hg in the profiles samples correlate with high concentrations of Cu, Pb, Ba, As, Cr and Fe and are a consequence of sulphide-barite mineralisation and historical copper and iron ore mining. The lack of correlation between Hg and organic carbon or phyllosilicates indicates physical weathering mechanisms and mechanical dispersion of mercury that contributes to the total flux of mercury in this region. Highly contaminated sediments might become an important source of Hg.

In this paper we study the boundary of the numerical ranges. Let S = {x : xx = 1, x ∈ C}. The numerical range of an n × n complex matrix A is defined to be the set W (A) = {xAx : x ∈ S}. We list some fundamental properties in section 1. In section 2, we discuss the angle between xAy and yAx when xAx lies on the boundary of W (A). In section 3, we study properties of corner xAx of W (A). Finally we give some special geometry in section 4.


Saccharin-derived cyclic imines such as (I) can be used as direct nucleophiles in the asymmetric Michael reaction with α,β-unsaturated aldehydes such as (II) by using the iminium catalyst of a chiral secondary amine.


changes with focal mild chronic inflammation. No evidence of inclusion bodies or amyloid. Electron microscopy was negative for IBM. Because of recurrent weakness, patient was put on IVIG every 4 weeks for about 6 months and he gradually improved. At 10 months, electromyogram (EMG) and nerve conduction studies demonstrated a chronic axonal motor polyneuropathy without much spontaneous activity and neuropathic motor units. At 1-year follow-up, patient's strength was normal. This case is an unusual presentation of Acute Motor Axonal Neuropathy (AMAN), because of a relapsing pattern that has not been previously reported to our knowledge and may sometimes lead to diagnostic confusion. Acute motor axonal neuropathies can sometimes be confused with motor neuron disease, acute presentation of chronic inflammatory demyelinating polyneuropathy, and at times subacute myopathies. It is important to highlight that such cases are clinically responsive to IVIG and improvement on serial EMGs can be helpful as illustrated in this case. AMAN is a variant of Guillain–Barré syndrome (GBS). GBS is an acute onset peripheral polyneuropathy and has 4 clinical subtypes: Acute inflammatory demyelinating polyneuropathy; AMAN: Acute motor and sensory axonal neuropathy and Miller Fisher syndrome.1 Electrophysiology plays a determinant role in Guillain–Barré syndrome diagnosis, classification of the subtypes and in establishing prognosis.2 AMAN is a motor nerve selective and axonal variant of GBS. The characteristic electrophysiological pattern is low amplitude or absent CMAPs with normal sensory nerve potentials and reversible conduction block.3 AMAN progresses more rapidly and has an earlier peak than demyelinating GBS; tendon reflexes are relatively preserved or even exaggerated, and autonomic dysfunction is rare.4 AMAN electrodiagnosis is not always a marker of poor recovery.5 Almost all the severe AMAN patients who had slow recoveries over the first 6 months could eventually walk independently, although some required several years.5 This case points to keeping the differential diagnosis broad and include AMAN even when there is episodic worsening noted and to consider the EMG/NCS as a useful tool to capture interval changes.


The toxicity effects of nano-ZnO suspension on antioxidant enzyme system of zebrafish embryos were investigated for evaluating its potential ecotoxicity.Exposure to nano-ZnO suspension led to the decrease in glutathione (GSH) content,the inhibition in catalase (CAT) and superoxidase dismutase (SOD) activity,and the increase in MDA level of zebrafish embryo.The result demonstrates that oxidative stress was one of the mechanisms of nano-ZnO ecotoxicity.

Introduction: Major injury incidents in underground metalliferous and mineral mines are rare, but if, e.g., a major fire would occur, it is the emergency medical service (EMS) together with the mining company and rescue service who perform the rescue operation. Therefore it is important to develop safe and efficient rescue operation procedures for all the organizations involved, especially the EMS personnel. Aim: To examine EMS personnel's perceptions and experiences regarding underground mining incidents. Method: Individual interviews were performed with 13 Swedish EMS personnel. The interviews were transcribed verbatim and analyzed with qualitative content analysis. Results: The theme "providing the same care in a difficult environment" emerged. Depending on the type of incident, the EMS personnel considered if the injured mining workers could be cared for either outside or in the mine in order to access and care for the injured mining workers as quickly as possible. The EMS personnel mentioned that it was difficult to make the decision if they should enter the mine or not due to the uncertainty of their safety. They also considered that it could be harder to accomplish the same level of care as in other incidents due to the difficult environment. In some instances, they cannot drive their ambulance vehicles into the mine, so they have to prioritize which equipment to bring as well as consider how to transport the patients. Discussion: The results identify some of the difficulties the EMS find challenging. Therefore the results could be used in finding solutions and making the EMS prepared for an effective and timely response for injured in underground mines.


Terahertz band (0.1‐10 THz) communications is one of the candidates for 6G systems due to intrinsic massive bandwidth and data rate support. Having demonstrated the signi icant potential of THz band at various atmospheric alti‐ tudes, in this article, we discuss the prospects of THz communications for drone networks, more speci ically, for Drone Sensor Networks (DSNs). For 6G non‐terrestrial communication scenarios, drones will not only serve as on‐demand base‐stations, as supporting alternatives or backhauls for the terrestrial base stations, but they will also provide seamless connectivity for distributed monitoring and surveillance applications, which require an ultra‐reliable low latency service for carrying multimedia data. THz band sensing will also provide additional sensing capabilities from the sky to THz‐enabled DSNs. Presenting this vision, in this paper, we irst discuss possible use cases of THz‐enabled drone networks considering communication, sensing and localization aspects. Then, for revealing the capacity potential of THz‐enabled drone networks, we provide motivating channel capacity results for communication of drones at different altitudes, under ideal channel conditions with no fading and realistic channel with beam misalignment and multipath fading. We further present major challenges pertaining to employing the THz band for DSNs, addressing physical layer issues, followed with spectrum and interference management, medium access control and higher layers and security, while reviewing some prominent solutions. Finally, we highlight future research directions with Arti icial Intelligence (AI)/Machine Learning (ML)‐based approaches and mobile edge computing.

Introduction: Pregnancy can be associated with health risks for both the mother and infant, and specialised care during the pregnancy, delivery and puerperium periods can help reduce complications for the mother-infant binomial. Objective: To assess the demographic, social and reproductive aspects of delivery and the postpartum period in Rio Branco, Acre, Brazil. Methods: A population-based cross-sectional survey was conducted via an interview with 552 mothers with children aged 0 to 5 years between 2007 and 2008. Cluster sampling of the population was performed in two stages (census sectors and domiciles). Results: The majority of the 552 mothers were multiparous (79.6%). Around 70% of pregnancies occurred in teenage mothers. The proportion of caesarean section deliveries was 38.4% in mothers from urban zones and 28.5% in those from rural areas, and was higher in mothers who attended private clinics, who self-reported as being Caucasian, and who had a higher educational level. With regard to puerperal complications, mothers who underwent caesarean section had a higher prevalence of hypertension (71.1%) with an adjusted prevalence ratio of 3.90 (95% CI [2.00, 7.61]). Conclusions: The results revealed a high rate of teenage pregnancy, and arterial hypertension was the leading complication during the postpartum period experienced by women who had undergone caesarean section. These findings merit further attention, and should be used to improve the care provided to Rio Branco.


We give geometric constructions of families of graded Gorenstein Artin algebras, some of which span a component of the space Gor(T ) parametrizing Gorenstein Artin algebras with a given Hilbert function T . This gives a lot of examples where Gor(T ) is reducible. We also show that the Hilbert function of a codimension four Gorenstein Artin algebra can have an arbitrarily long constant part without having the weak Lefschetz property. In R = k[x;y] and in R = k[x;y;z], the parameter space Gor(T ) of graded Gorenstein Artin quotients of a given Hilbert function T is irreducible for all T . The codimension two case is implied by F. S. Macaulay's result that Gorenstein height two ideals ink[x;y] are complete intersections [8], and the fact that the family of graded complete intersection ideals of given generator degrees is irreducible. The codimension three case was proved S. Diesel [4]. A. Iarrobino and V. Kanev [7] have recently shown that in codimension ve and higher, Gor(T ) can be reducible. In this paper, we will give a large class of examples where Gor(T ) is reducible, in codimension four and higher. A. Iarrobino and V. Kanev also proved that there is a close relation between graded Gorenstein Artin algebras of codimension three and nite length Cohen-Macaulay sub-schemes of P 2 . They show that whenever the Hilbert function T is equal to s for at least three degrees, there is a bration Gor(T )! H(T ) Hilb s (P 2 ) which takes the form f to the initial part of the ideal annR(f). We prove that there can be no such results in higher codimensions, by showing that for r 4, there are codimension r Gorenstein Artin algebras with arbitrary long constant part in the Hilbert function, whose initial ideal does not dene a sub-scheme of length s in P r 1 . The

FIELD: road-building and insulating materials. SUBSTANCE: method for preparation of bitumen-polymer composition consists in melting of bitumen components at 60-180 C and formation of granules encased in shells of thermoplastic polymer. Prior to use, granules are melted and mixed at 160-200 C. Bitumen component with temperature 60-180 C is supplied by gravity or at pressure into polymer shell which forms moving sleeve and is granulated. Also bitumen component at temperature of 60-100 C, first, is granulated and then, applied to granules in polymer melt, and cooled in water or air. Used as bitumen component is bitumen, mixture of bitumen with thermoplastic polymer or with its wastes in the amount of 1-15% of mass of bitumen composition, and also bitumen-polymer, bitumen-asbestos, rubber-bitumen mastics. Besides, granule shell is made of same polymer used in bitumen component. Method provides for convenience in storage and transportation of composition, and also its protection from moistening and contamination. EFFECT: higher efficiency. 7 cl

Herein, we introduce a novel effective band tuning method in hybrid tin iodide perovskites using a different group element. With this method, band gap reduction down to 0.8 eV is observed in tin (group 14) iodide-based hybrid perovskites as a result of bismuth (group 15) doping. In this solution-processable material, the band gap is continuously controllable in the range from 1.3 to 0.8 eV even when the doping level was less than 10%. The effect of "foreign metal" doping on the band gap is larger than that of the mixed crystal with the same group elements. Bismuth doping reduces the conductivity of the materials depending on the doping levels though their behavior is still clearly metallic. From the results of the electronic structure and electronic properties of this material, it is clear that bismuth doping causes the narrowing of the band gap without changing the energy and DOS at the top of the valence band, and without increasing the number of carriers. The band tuning method will be useful for the design of solar cells.


associated with poor outcomes [2]. Despite treatment, mortality remains unacceptably high, and many sufferers from SE end up with permanent brain damage, especially in the limbic system, resulting in memory loss, cognitive dysfunction, epilepsy and other neurological conditions [3S5]. Rapid control of seizures is fundamental in decreasing longSterm sequellae [6] and neurological injury. Implementing SE protocols in emergency rooms and intensive care units may help speed up initiation of therapy, improve effectiveness and decrease the widespread problem of treatment being "too low, too slow" [7].


Objective: By comparing the evaluation effect of traditional physical examination (PE) and portable color Doppler ultrasound on arteriovenous fistula (AVF), to explore the value of portable ultrasound in the diagnosis of abnormal fistula lesions in patients with maintenance hemodialysis (HD). Methods: 57 patients with maintenance HD from Dongpu HD center, the first affiliated hospital of Jinan university from September 2019 to March 2020 were selected. The PE was performed by specialist nurses, and AVF was evaluated by portable ultrasound, and the general data of the patients were collected. Results: The average age of the HD patients was 58.98 years, including 31 males (54.39%). The median of HD duration was 56 months, and 22 patients (28.60%) had diabetes mellitus. The prevalence of fistula stenosis was 17.54%. 50% PE was abnormal in fistula stenosis group, which was higher than that in non-fistula stenosis group (10.64%, P=0.012). The κ index was 0.394 in the consistency assessment between PE and portable ultrasound for evaluating the fistula stenosis (P=0.003). The incidence of fistula sound reduction, blood flow less than 200mL/min during treatment and abnormal arm lifting test in patients with fistula stenosis were all higher than those without fistula stenosis (all P<0.05). The results of multivariate logistic regression analysis showed that abnormal PE was closely related to fistula stenosis (OR=8.400, 95% confidence interval (CI)=1.786-39.498, P=0.007). Conclusion: Portable color Doppler ultrasound could effectively diagnose AVF stenosis in maintenance HD patients, especially when the traditional PE was abnormal, timely portable ultrasound evaluation was conducive to early intervention and extend the life of AVF.


Objective To investigate the relationship between developmental coordination disorder(DCD) and attention deficit hyperactivity disorder(ADHD) in children.Methods Sixty child outpatients with attention deficit hyperactivity disorder were evaluated by Developmental Coordination Disorder Questionnaire(DCDQ)for DCD and integrated visual and auditory(IVA) test for ADHD.Results Some 20% of children with ADHD were associated with DCD,33.3% were suspected to have DCD.There was high percentage of DCD symptoms in all three types of ADHD,with 25% of the ADHD-predominantly inattention type(ADHD-PI),20% of the ADHD-predominantly hyperactive-impulsive type(ADHD-HI),and 22.2% of the ADHD-combined type(ADHD-C).There was no significant difference among the three ratios(P0.05).Conclusion Hyperactivity disorder is closely associated with DCD,and its three sub-types are all associated with DCD,which provides a new thought for treatment of hyperactivity disorder.

Objective: To evaluate the effects of percutaneous balloon pulmonary valvuloplasty ( PBPV) for pulmonary valve stenosis (PS) by single-balloon, double-balloon and Inoue-balloon methods. Methods: PBPV was performed in 42 patients with PS. The systolic right ventricular pressure (SRVP) , systolic right ventricular outflow pressure and systolic pulmonary arterial pressure ( SPAP) were contrasted before and after the procedure. Systolic transpulmonary valve pressure gradient (TVPG) and total pressure gradient from right ventricular to pulmonary arterial after the procedure were compared among the three gropes. Results:SRVP, SRVOP were decreased from (14. 69±6. 01 )kPa, (12. 16±3. 48)kPa to (8.14±5.26)kPa, (5.39±2.21)kPa and PAP increased from (1.57±0.56)cm to (17. 16± 2.16)cm after PBPV, respectively. TVPGs were (2. 40±2. 05) kPa, (3. 29±2. 25 ) kPa, (2.52± 1.95)kPa and TPGs were (2. 40±2. 05)kPa, (4.98±4.26)kPa, (6.16±6.93)kPa, (5.65±4.75) kPa after PBPV by single balloon, double balloon and Inoue balloon methods, respectively. During the follow-up period (2. 5±1. 6) years, bloodflow velocity at pulmonary valve measured by supersonic Doppler decreased from (2. 38±1. 89) m/s immediately after PBPV to (2.22±1. 96) m/s, further TVPG decreasing was indicated. Conclusion: The short and long term results of PBPV for PS by each of the three methods were excellent. Inoue balloon may be the first choice for elder children and adults, while for younger children, single balloon method may be preferred. Double balloon method can be remained as the second choice when Inoue method failed.

The cationic graft copolymer was synthesized byreversed phase emulsion copolymerization of starchwith diallydimethyl ammoniumlchlorid (DADMAC)and acrylamide (AM). The copolymerization wascarried out using (NH4)2S2Os-NH2CONH2 redox asinitiator and selecting Span-20 as emulsifier. Theeffects of emulsifier content in oil phase, volumeratio of oil to water, initiator concentration and moleratio of DADMAC to AM on the graftcopolymerization were discussed. The optimumcondition of synthetics was found with theorthogonal test method.


Based on the D-H displacement matrix method,variable space model and trigonometric function relationship,the working device of hydraulic excavators is investigated.Accordingly,the generic expression is deduced for variable space transformation.By analyzing the traditional trajectory planning methods for robotic excavators,the operational features and demands on hydraulic excavators are speculated.Further studied,a fuzzy velocity method is proposed based on the real-time control signals.So far,the contradiction between the unknown loading and predetermined movement velocity amongst traditional methods is completed avoided.Therefore,this approach guarantees that the working device tracking intended trajectory accurately by an appropriate speed.


Vials have been filled with antibiotic powder in a computer-controlled vacuumheld volumetric filling machine. Each port on a rotating wheel is filled from a hopper by the application of a vacuum, and the resultant powder plug ejected into a vial by pressurised air. The intermittent motion of the filling wheel is controlled by a computer-driven stepping motor so that the angular vel.ocity of the wheel and the dwell time for powder filling are independently controllable. These two parameters cannot be separately adjusted on conventional industrial filling machines. In addition to rotational speed and dwell time control, the machine used was fitted with port lining bushes that allowed a powder plug to be removed entire, and to be sectioned, so that variation of bulk density through its depth could be measured. Several*batches of fine grade cefuroxine sodium (median size 10-20 urn, compressibility 4 0 4 0 % ) differing slightly in filling behaviour were filled into glass vials over a range of conditions, using different powder plug lengths, filling speeds, dwell times and hopper-agitation speed and applied suction levels. Fill weight increases with plug length, but in a non-linear fashion, (Fig 1 ) the nonlinearity depending upon other conditions, notably the dwell time and the hopperagitator speed. Fill-weight variability, assessed as coefficient of weight variation (CV) generally decreases with increasing dwell time, increasing agitator speed (Fig 2), applied suction, and plug length. The utility of the results and their correlation is that a required fill-weight and an acceptable CV can be chosen. The increased CV consequent upon an increased production rate can be reduced by increasing the hopper-agitation rate and the applied suction. Large fill-weights or modest fills of awkward powders are achieved by multiple-shot filling into each vial. Filling rates for double shot filling are usually substantially lower than for single shot. However, careful selection of filling conditions can result in a reduced coefficient of fill weight variation with small losses of production capacity. The method enables the optimisation of such filling conditions to be carried out.


The determination of absolute branching ratios for high-energy states in light nuclei is an important and useful tool for probing the underlying nuclear structure of individual resonances: for example, in establishing the tendency of an excited state towards
α
-cluster structure. Difficulty arises in measuring these branching ratios due to similarities in available decay channels, such as (
18
O,
n
) and (
18
O,
2
n
), as well as differences in geometric efficiencies due to population of bound excited levels in daughter nuclei. Methods are presented using Monte Carlo techniques to overcome these issues.

The variability of RS Columbae (634.1935; CoD — 28°2059; CPD — 28°817) was discovered by Hoffmeister (1935, 1942). His subsequent work (Hoffmeister 1943a,b) indicated that the light variation was of small amplitude, approximately 0TM4, with a periodicity of 14.66. The light curve appeared to be that of a cepheid of the f Geminorum type, although it was noted that the observations were few in number and of low precision. At a galactic latitude of —32°, the star would lie upwards of 2 kpc from the galactic plane if it were indeed a cepheid variable, and would probably be one of the brighter of the W Virginis-type variables. Photometric observations were therefore undertaken by one of us (A.U.L.). The photoelectric data reported herein were obtained at the No. 2 16-inch telescope of the Cerro Tololo Inter-American Observatory in 1967 and at the No. 1 16-inch in 1969. A standard set of UBV filters, a refrigerated 1P21 photomultiplier, and observations of numerous UBV standard stars (Johnson and Harris 1954) each night permitted the transfer of all data onto the UBV photometric system. Since RS Columbae presumably had a long period, only one observation per night was obtained on 23 nights in 1967; no comparison stars were used. Mean extinction coefficients were used in the data reduction process outlined by Schulte and Crawford (1961). The external probable errors of the 1967 magnitudes and color indices

Abstract In this work, a study on failure by concrete pry-out in Crestbond shear connectors is presented. The study's aim was the development of an expression that estimates the connection's bearing capacity. The analyses were carried out through numerical simulations designed to reproduce the referred failure mode. Numerical and experimental results are compared and discussed in relation to the maximum force reached and the cracking aspect typical of concrete pry-out. The proposed equation corresponded well to experimental results, with a mean ratio Ptheo/Pexp equal to 0,99 and a coefficient of variation of 10%. The results found in this study indicate that the concrete pry-out expression in German Technical Approval Z-26.4-56 can also be applied to Crestbond shear connectors.


Ka band is widely used in satellite communication. Up-converter and down-converter modules, for Ka band, are plaintively availabel in market for commercial use. These modules works for specific band like 29.25-30.20GHz to 950-2000MHz, 17.7-21.2GHz to 140/70 MHz, vice versa, and combination of these. They are availabel in standard form factor, and may not suite specific requirements. The 30 GHz to 70 MHz down converter (DC) in a small form factor is specific requirement for re-entry ground telemetry station. This Paper describes the design and simulation results of this DC module. The 30 GHz to 70 MHz down conversion is achieved in three stages. The module is designed to operate for dynamic range of −90 dBm to −10 dBm. The simulated design with vendor components have cascaded gain of 67 dB for input power of −90 dBm and return loss of −17 dB at 30GHz.

Our paper presents the first application of a fiber-optic interferometric sensor to real-time monitoring of dynamic pressure and temperature in the exhaust pipe of an automotive engine. The sensor is based on highly birefringent fibers, where the phase shifts between two pairs of polarized modes are induced by two measurands and decoded simultaneously using a coherence-addressing principle. The system allows for unambiguous measurement of pressure and temperature changes in the range of 140 mbar and 100/spl deg/C, and with an accuracy of 2 mbar and 0.4/spl deg/C, respectively, at a sampling rate up to 200 kHz. Preliminary testing of the sensor provided data that allow determination of the flow of exhaust gases and gives information about mass emission. Additionally, the dynamic measurements of pressure make possible diagnosis of the engine operation.

Several bills called the so-called 'Yellow Envelope Act' have been submitted to prevent the contraction of the three labor rights due to lawsuits for damages by expanding the requirements for exemption from liability for damages caused by trade union strikes. Expanding the scope of workers and employers and labor disputes and reducing the scope of liability for damages caused by unjust (illegal) industrial actions means further restricting the guaranteed occupational freedom and property rights of employers. However, freedom of occupation or property rights can be restricted, and these constitutional economic rights can also be restricted by the order of the social market economy. Therefore, it is necessary to guarantee the three labor rights by including those with employment in the category of workers, not only those who provide work by signing a formal labor contract and agree to receive wages or salaries, but also those who have not concluded a formal labor contract, are in the same or substantially similar legal status as workers who have entered into a formal labor contract. Otherwise it is necessary to recognize the same three labor rights guaranteed to workers as those workers who have not conclude labor contracts through additional legislation.
On the other hand, considering the fact that restrictions on occupational freedom or property rights have already been made at the constitutional level by the Constitution guaranteeing the three labor rights as constitutional rights, the right to claim damages can be applied not only in legitimate industrial actions but also in unjust industrial actions, it seems necessary to reduce it within a reasonable range. Furthermore, when the principle of proportionality, especially the balance of legal interests, is used as the criterion for judging both the three labor rights of workers and the property rights of employers, compensation for damages that make the existence of a trade union impossible or does not meet the financial scale of the trade union should not be recognized. Finally, democratization of the economy, which the Constitution enumerates as a public purpose of state intervention in the market, emphasizes the participation of all members with interests in economic decision-making. Therefore, even though layoffs for corporate restructuring basically belong to the realm of management rights, it seems that they can be included in the subject of labor disputes so that the opinions of workers, who are interested parties, can be reflected.


Editor—We agree with Charles Vincent that clinical risk management should be integrated with other quality assurance programmes and that its aim should be more ambitious than simply avoiding litigation. Indeed, evidence that clinical risk management can reduce litigation is limited, so continued justification for the approach may depend on its ability to improve patient safety. We introduced a clinical risk management programme in obstetrics in Oxford in September 1994. The cornerstone of the programme was an early warning system for adverse events. Our definition of an adverse event was any unexpected event or outcome of pregnancy that has (or might have) a significant short or long term detrimental effect on either mother or infant. All clinical staff were encouraged to report such events to a perinatal risk coordinator, who was a midwife. In addition, the perinatal risk coordinator screened the birth registers of delivery suites for possible adverse events. Over one year 423 adverse events were identified, which is the equivalent of one for every 15 deliveries. Fourteen of the events were assessed as carrying some risk of litigation. In these cases, written statements were taken if appropriate from relevant clinical staff and the trust's solicitors were contacted at the discretion of the trust's legal department. Staff were encouraged to discuss what had happened with the family. A multidisciplinary clinical risk management group met every fortnight to review contemporary adverse events and make recommendations for clinical practice and service development. Between September 1994 and December 1996 six claims were made against the unit that related to obstetric care over these 28 months. Only three of these claims had been identified prospectively by the early warning system. However, the average time lag from incident to claim is five years, so further claims are likely to arise. Our initial experience is that an adverse event detection system is neither sensitive nor specific for possible medical negligence claims. The Harvard medical practice study reached similar conclusions. Thus, an early warning system for adverse events is likely to have only a limited impact on the direct costs of medical negligence litigation relating to such events since it will identify only some of those that will lead to claims. Clinical risk management may have only a limited impact on medical negligence litigation, but it might have potential in improving patient safety. Formal evaluations of clinical risk management in this role should be performed.


To the Editor: Waiting for appointments is unavoidable in a hospital setting. Shortening wait times is not always possible, but patients report higher satisfaction when they are provided information about their wait. Patients value information that reduces the uncertainty of their waiting time or explains delays. We implemented and installed wait time displays in 2 imaging facilities at Massachusetts General Hospital. In one, an X-ray walk-in facility, the display shows the anticipated wait time for arriving patients. In the second facility, an appointment-based mixed-modality imaging center, we display the anticipated appointment delay for each type of imaging. Wait and delay predictions were made using a linear regression based on the size of the waiting line and previous appointments' delays. To assess the value of the displays, we handed out a reaction survey (shown below) with the pre-exam paperwork at patient check in.


Primitive root is a fundamental concept in modern cryptography as well as in modern number theory. Fermat prime numbers have practical uses in several branches of number theory. As of today, there is no simple general way to compute the primitive roots of a given prime, though there exists methods to find a primitive root that are faster than simply trying every possible number. We prove the equivalence between the primitive roots and the quadratic nonresidues modulo Fermat prime numbers. Therefore, the problem of searching primitive roots is transformed into solving the quadratic residues modulo Fermat primes, which is a much easier problem, having very simple solutions. Theoretical analysis and experimental results verify our conclusion.

Summary

Plant damage and reduced yields were associated with delayed ammonification or nitrification of added urea-nitrogen. In a neutral sandy loam, the adverse effects of urea application were associated with the accumulation of toxic levels of first ammonia and later nitrite. Addition of hydrogen-ion as phosphoric or sulphuric acid alleviated the damage thereby supporting the conclusion that ammonia and nitrite accumulation were the causes of phytotoxicity. In an acid sand, toxicity was associated first with the presence of large quantities of urea remaining in the soil though the evidence was insufficient to show in what way the urea was toxic. There was then a second phase of toxicity associated with the presence of considerable quantities of ammonium-nitrogen under conditions where toxic levels of ammonia were likely to have occurred. The later phase (nitrite toxicity) did not occur. Phytotoxicity arising from urea addition to the soil could be due apparently to the persistence of urea as such in the soil and also to the accumulation of significant quantities of free ammonia and nitrite. The occurrence of one or more of these phases of urea toxicity depended on differences in soil conditions.

In this work, we address the articulation between politics, cultural diplomacy and cinema, in relation to Argentina's ties with Nazi Germany in the period prior to the declaration of World War II. First, we characterize the cultural relations between Germany and Argentina, taking into account the deployment of German cultural diplomacy in the country and the links it established with the local community, particularly in the field of cinema. In the second section, we describe the circulation of German cinema in Buenos Aires in the period from 1935 to 1939, with the outbreak of war. There, we analyzed the role of the main German cinema distributors, their contacts with German producers and with a certain theater circuit. We deal especially with the titles that were later censored for being considered «nazi propaganda» in terms of their permanence in theaters and critical reception.
