Determination of Loratadine in Human Plasma by High Performance Liquid Chromatography-Electrospray Mass Spectrometry and Studies on Its Pharmacokinetics and Relative Bioavailability

A new HPLC MS method to determine loratadine in human plasma was established. The method involved extracting drug with organic solvent under basic conditions. The samples were seperated by ODS column and determined by mass detector. The calibration curve of loratadine was linear within the range of 0.4～100 ng·mL -1 with r=0.9995 . The recovery of this method was within 95%～104%, within day and between day RSD were less than 12%. To study the pharmacokinetics and relative bioavailability of loratadine tablets, two formulations of loratadine tablets were given to 18 healthy male volunteers according to a randomized 2 way cross over design. The C max , AUC 0 t and T max values of the two formulations were 51.89±20.18 ng·mL -1 and 52.48±22.35 ng·mL -1 ; 140.75±88.42 ng·h·mL -1 and 147.24±92.33 ng·h·mL -1 ; 0.81±0.35 h and 0.81±0.27 h respectively. Results from statistic analysis showed that there were no significant difference between the C max , AUC 0-t and T max values of the two formulations. The relative bioavailability of tablets I with respect to tablets II was 97%±13% from the AUC 0 t measurement. Bioequivalance was observed between the two tablets.

Integrated Futures for Europe’s Mountain Regions: Reconciling Biodiversity Conservation and Human Livelihoods

Europe＇s mountains cover nearly half of the continent＇s area and are home to one fifth of the European population. Mountain areas are hotspots of biodiversity and agriculture has played a multifunctional role in defining and sustaining mountain biodiversity. Ongoing trends of agricultural decline are having negative impacts on mountain biodiversity. This paper presents results from an interdisciplinary European research project, BioScene, which investigated the relationship between agriculture and biodiversity in six mountain study areas across Europe to provide recommendations for reconciling biodiversity conservation with social and economic activities through an integrated rural development strategy. BioScene used scenario analysis and stakeholder participation as tools for structuring the analysis of alternative mountain futures. Three main BioScene scenarios were evaluated： Business as Usual （BAIT）, Agricultural Liberalisation （Lib）, Managed Change for Biodiversity （MCB）. BioScene brought together ecologists, economists, sociologists and rural geogra- phers, to carry out interdisciplinary analysis of the scenarios： identifying key drivers of change, assessing the biodiversity consequences and evaluating costeffectiveness. BioScene used a sustainability assessment to integrate the research outputs across natural and social science disciplines to assess the broader sustainability of the scenarios in terms of biodiversity, natural resources, rural development, social development, economic development and institutional capacity. The sustainability assessment showed that the MCB scenario was potentially the most sustainable of the three BioScene scenarios. Through the reconciliation of potentially conflicting objectives, such as conservation, economic development and human livelihoods, and with a strong participatory planning approach, the MCB scenario could represent an alternative approach to BaU for sustainable rural development in Europe＇s mountains. BioScene confirms the necessity for natural and social scientists to work together to seek solutions to environmental problems. Interdisciplinary research can assist with the definition of integrated strategies with the potential to reconcile the ecological, social and economic parameters that determine a sustainable future for European mountain areas.

Is changing footstrike pattern beneficial to runners?

Some researchers, running instructors, and coaches have suggested that the "optimal" footstrike pattern to improve performance and reduce running injuries is to land using a mid-or forefoot strike. Thus, it has been recommended that runners who use a rearfoot strike would benefit by changing their footstrike although there is little scientific evidence for suggesting such a change. The rearfoot strike is clearly more prevalent. The major reasons often given for changing to a mid-or forefoot strike are(1) it is more economical;(2) there is a reduction in the impact peak and loading rate of the vertical component of the ground reaction force; and(3) there is a reduction in the risk of a running-related injuries. In this paper,we critique these 3 suggestions and provide alternate explanations that may provide contradictory evidence for altering one's footstrike pattern.We have concluded, based on examining the research literature, that changing to a mid-or forefoot strike does not improve running economy, does not eliminate an impact at the foot-ground contact, and does not reduce the risk of running-related injuries.

Dynamic simulation and experimental study of inspection robot for high-voltage transmission-line

A mobile robot developed by Wuhan University for full-path hotline inspection on 220 kV transmission lines was presented. With 4 rotating joints and 2 translational ones, such robot is capable of traveling along non- obstaclestraight-line segment and surmounting straight-line segment obstacles as well as transferring between two spans automatically. Lagrange’s equations were utilized to derive dynamic equations of all the links, including items of inertia, coupling inertia, Coriolis acceleration, centripetal acceleration and gravity. And a dynamic response experiment on elemental motions of robot prototype’s travelling along non-obstacle straight-line segment and surmounting obstacles was performed on 220 kV 1∶1 simulative overhanging transmission-line in laboratory. In addition, dynamic numerical simulation was conducted in the corresponding condition. Comparison and analysis on results of experiment and numerical simulation have validated theoretical model and simulation resolution. Therefore, the dynamic model formed hereunder can be used for the study of robot control.

Global progress against cancer—challenges and opportunities

The last ten years have seen remarkable progress in cancer research. However, despite significant breakthroughs in the understanding, prevention, and treatment of cancer, the disease continues to affect millions of people worldwide. Cancer＇s complexity compounded with financial, policy and regulatory roadblocks has slowed the rate of progress being made against cancer. In this paper, we review a few of the most recent breakthroughs that are fueling medical advances and bringing new hope for patients affected by this devastating disease. We also address the challenges facing us and the opportunities to accelerate future progress against cancer. The efforts of the American Association for Cancer Research （AACK） to address the cancer burden already extend beyond the borders of the United States of America. The AACR is committed to increasing its efforts to stem the tide of cancer worldwide by promoting innovative programs, strategies, and initiatives for cancer researchers and all those engaged in cancer-related biomedical sciences around the world.

Building Features in Schools That Influence Academic Performance

School decision makers are faced with a great many decisions when considering a school renovation or new school building. All stakeholders want a building that is safe and provides an optimal learning environment. However, it is often difficult to know which building features will have the greatest effect on student learning. Because of a limited understanding of the relationship between individual building features and student learning, researchers at the University of Oklahoma hope to explore how building components influence student and teacher performance. This paper explores the importance of school building features that can be designed and changed during a renovation project. The hope is to one day determine which features have the greatest impact on student test scores. The research team believes that although it is difficult to find the exact relationship between each building features and student outcomes with one study, if multiple users repeat the same or similar studies, hopefully we will one day know the effect of these building features. In order to develop feature building users survey and physical assessment tools, it was necessary for investigators to develop a list of important building features and their associated definitions in layman terms. This was accomplished through utilization and conducting of a CAB （community advisory board） and subject matter expert materials. In addition, previous research relating to different school building features and their associations with student performance were reviewed. To define and narrow the list the researchers, community educational, and building professionals rated based on their professional experience, how directly related each feature is to student performance. The building feature list serves as a starting point to determine which features should be analyzed in a later phase of the project. It is hoped that resulting tools based on the work of this project can be used by school decision-makers and researchers to access building features that have been identified through research as being important for student and teacher performance.

The Impact of Handicrafts on the Promotion of Cultural and Economic Development for Students of Art Education in Higher Education

This paper studies the impact of handicrafts on the promotion of cultural and economic development for students of art education in higher education through handicrafts based on local customs and traditions. Descriptive, analytical, and experimental methods are used in this research. The results of the study are expected to benefit from the results of this study to provide planners handicrafts in the Ministry of Education. An effective strategy can affect the teaching and learning of handicrafts, the protection of its features and its presence and identity. The study sample consists of 45 students of the third level, batch 2012-2013, from the faculty of Education at the University of Khartoum, Republic of the Sudan. The researchers to prepare topics for handicrafts depend on the use of local materials and units which are derived from the environment and represent the Artistic heritage that is shown through handicrafts （pottery, ceramics, calligraphy, decoration, carpet weaving and textile, sewing, embroidery, sculpture and engraving on wood, metal works, and printing works）. The researchers focuse that the students learn the value of handicrafts in terms of economic and method of production and take advantage of it to increase the income of the individual product. The results confLrms the existence of a difference in the quality and value of handicrafts for students in both groups： the experimental and control group, which confirms that the handcrafts lead to the promotion of cultural and economic development for students of art education in higher education. The researchers are recommended to consider of this topic as a main component which enables an area for further studies to develop different strategies in the field of handicrafts, for students to recognize the importance of the handicrafts value in terms of economic and method of production and take advantage of it to increase the income of the individual product.

Developing Theoretical Relativistic Framework for Research in Open and Flexible Learning： A New Trend in Educational Research

The purpose of research study was to develop a theoretical relativistic framework for research in open and flexible learning environment because it is a new dimension in the field of education. Developing a theoretical relativistic framework for any research study is first and prime step in walking on the track to reach the distinction set by the researcher. Open and flexible learning is a new trend in education, enriched with ICT-use as a basic demand of the 21st century generation in all parts of the globe. So, it requires a theoretical framework for its initiation, implementation, development and evaluation which is relatively developed and advanced from the existing framework. In any research study the literature review is carried out in order to develop, build or construct a theoretical framework. The researcher of the study has observed while attending the international conference on ODL （AAOU, 2013） that most of the studies require theoretical underpinning for ICT-use in education. The researcher assume that being a new trend in education to use ICT for teaching learning purpose; it requires conceptual clarity and theoretical background of the user and researcher, because, without theory the practice is wastage of money, time and energy and it becomes ineffective and requires relatively new conceptual development. So, the problem stated by the researcher for the study was： Developing theoretical relativistic framework for research in open and flexible learning： A new trend in educational research. The objective of the study was integrating the interrelated concepts to build a pnemonological network for identifying the constructs in ICT-rich open and flexible learning environment. The study was significant because it provided theoretical background for conducting research in ICT-use for teaching and learning through open and flexible systems; whether blended or online learning and training. The methodology used by the researcher was qualitative and interpretive because there were reviewing of literature and meta-analysis for building the framework. The data were analyzed and interpreted by the researcher for the findings and drawing conclusions. On the basis of conclusions the researcher has made suggestions and recommendations for conducting research in open and flexible learning environment by using this theoretical relativistic framework. The framework was named as Virtual Learning Environment Framework （VLEF）.

CARPAL TUNNEL SYNDROME：ETIOLOGICAL，CLINICAL AND ELECTROPHYSIOLOGICAL ASPECTS OF 262 CASES

Two hundred and sixty-two patients with carpal tunnel syndrome (CTS) were analyzed retrospectively. Results showed that middle-and older-age women were more apt to have CTS than men, and that the dominant hand was more frequently affected. Hormonal changes , repetitive and forceful movements, awkward positions of hand and wrist, and other factors may be associated with CTS. Typical clinical manifestations include pain and paresthesia in the median nerve territory, worsening at night or in the early morning , and being relieved by shaking the hand. Although the patients may localize the discomfort beyond the territory, sensory changes are variable and not entirely reliable. Conduction abnormalities often appeared selectively in the median nerve distal to the wrist in CTS. If the patient who is clinically suggestive of CTS shows normal conduction with conventional methods, palmar stimulation and inching technique is recommended. The diagnosis of CTS requires confirmation of illness history, symptoms and signs with objective electrodiagnostic tests.

International School of Egyptology of Adolf Erman

The world admired Ancient Egypt since its conquest by the Roman Empire, For Europe, it was a dreamlike country full of wonders and magic, only in the beginning of the nineteenth century, the romantic interest gave way to serious scientific research. The founders of Egyptology widely known, hut the name of one of them, the German Egyptologist Adolf Erman, is rarely found in modern monographs of Western researches, dedicated to the history of Egypt. At the same time in Russia, where researches in the field of Egyptology have been started only in the late nineteenth century, a special attention was paid to Erman＇s works. The objective of this work was to evaluate the significant contribution of A. Erman to the development of the world and in particular Russian Egyptology. Analysis of Erman＇s, his disciples＇ and followers＇ works showed that he was the founder of the Berlin school of Egyptology which has brought up such famous Egyptologists as L. Borchardt, K. Zeta, H. Muller, G. Roeder, H. Schaefer, G. Shteindorf, and others. His influence went far beyond Germany： Among his students, there were researchers from England, the United States of America, and italy. Erman left a remarkable imprint on Russian Egyptology. B. Turayev and V. Struve were taught by Erman, then they became followers of this science at home; some of their students undertook an internship at Erman＇s school as well. After returning home the Russian researchers created works on the history and culture of ancient Egypt, lecturedon Egyptology in universities. As a result, Russian schools of Egyptology were founded by B. Turayev and V. Struve, the members of which proceeded to work on the history of Egypt and Ancient Orient, transferring their knowledge to the next generation.

Italian Accounting of the Late 19th Century and the Early 20th Century on the Epistemological Problem of Connections With Related Sciences

This paper takes into consideration the doctrinal positions that are taken by Italian accounting in the period between the 19th and the 20th century, and concerns the nature of relationships between accounting and its most similar sciences, particularly economics. Over those years, the scholars in that field started to show a peculiar epistemological sensitivity. Spurred by the philosophical debate which was raised by positivism and particularly by Comte＇s and Spencer＇s studies, researchers wondered whether the most appropriate place for accounting was in the large field of social sciences. Hence, two different epistemological approaches arose with one succeeding the other in time. Initially, scholars accepted the idea that accounting somehow depended on its related sciences, which included economics. They deemed it convenient to use, also for their own purposes, principles drawn from contiguous doctrines that had already been scientifically recognized, such as economics. That was how Italian accounting happened to be, even though temporarily, in a position of ＂scientific subjection＂ with respect to the mentioned doctrines. At the second stage, due to the awareness of the specific subject and the method of investigation, as well as the purposes, Italian accounting claimed its own scientific autonomy, so scholars went back to the first phase and considered it necessary to develop internal principles and rules as a function of its peculiar needs. By doing so, scholars mapped out a route that would deeply mark the future of the discipline by making it fully independent on other fields of knowledge in a sort of emancipation process. The paper will not only describe the two theoretical positions which are summarized above, but will also adopt an interpretative approach to trace their possible causes and to grasp their effects on the development of the discipline, particularly with regards to the theories of value which is adopted by the Italian accounting over the analyzed period. In the authors＇ opinion, the attention paid by the most authoritative Italian accounting scholars to the epistemological theme of relationships between accounting and its similar sciences can be explained by at least two different causes： the influence which is exercised by the philosophical studies and the aspiration of accounting for scientific and academic recognition.

The Catastrophic Effects of African Americans＇ Marginalisation in Ralph Ellison＇s Invisible Man and August Wilson＇s Fences： A Comparative Study

This paper explores Du Boisian notion of double consciousness and the notion of black nihilism suggested by Cornel West in Ralph Ellison＇s Invisible Man （1952） and August Wilson＇s Fences （1986）. In order to conduct this study, the researcher adopts African American approach and shows that double consciousness and black nihilism are the immediate effects of African Americans＇ marginalisation. According to W. E. B. Du Bois, all African Americans develop the sense of double consciousness which means being both African and American simultaneously. On the other hand, Cornel West believes that black Americans suffer from nihilism which means loss of hope and absence of meaning. The paper is an attempt to compare the novel Invisible Man and the play Fences thematically based on these two theories. It then looks to find the considerable similarities in the conditions of the protagonists of these two literary works. Although both protagonists migrate to the North to escape Southern racism in the era prior to the Civil Rights Movement, they become totally disillusioned, for they are treated as the invisible marginal. Interestingly though, at the end of both stories, there remains a ray of hope for reactivation and the creation of democracy for black Americans.

Teaching Chinese to English Tour Guide Interpreting

In the present study, some junior students of the English major were asked to verbalize or write their thoughts after interpreting. Besides, students＇ errors were also identified through observations by the researchers. As a result some of the mistakes made by students were found： lacking humor and variety in their interpreting, little vocabulary and variation in expression, etc.. Reasons were also analyzed which included that students were generally not familiar with some of the often-used sentence patterns for tour guide interpretation, and teachers are not using the suitable ways of teaching tour guide interpreting. To conclude, ways to solve these problems were recommended for readers＇ reference.

A Review of Shipowner＇s ＆ Charterer＇s Obligations in Various Types of Charter

The charterparty is a legal contract of employing a vessel. In shipping matters, it is a highly important document since it allocates obligations, rights, duties, liabilities, risks, earnings, costs and profits between the contracted parties, namely, the shipowner and the charterer. The interpretation of the above mentioned matters, as well as the understanding of charterparty terms, is considered of critical importance in chartering practice. Therefore, this paper constitutes a review of the most important aspects arising from charterparties in the main types of charter. The present study is based on shipping practices followed in accordance with the English Common Law throughout the chartering process （pre-fixture, fixture, execution of the charter, post fixture）. This is a synopsis about the distribution of the liabilities and expenses between the shipowner and the charterer in the most representative types of charter. The analysis is seen from a commercial stand point. Therefore, it is mostly addressed to the shipping practitioners, maritime economists, academics, students and researchers who seek to form a comprehensive view on the subject. It may also form a basis for further study on chartering aspects （legal, economic, managerial and practical）.

Work Transformations and Their Consequences for the Personal Life of Workers

The civilisation transformations which occur in the sphere of human work, have a strong influence over their functioning both in the professional and extraprofessional spheres. Scientific analyses, as well as everyday observation, suggest that there are increases in the tension between work and personal life, which results in imbalance and perceiving both the spheres as mutually contradictory, as well as having adverse consequences for workers and their families, organisations, the society, and economics. As regards this occurrence, the aim of the article is to show selected civilizational trends which generate the issues with maintaining work--personal life balance of contemporary humans. The article is of theoretical character and is based on the method of critical literature analysis, as well as on the analysis of formal-legal documents, reports, and statistical sources. The theoretical-case analyses let one formulate a conclusion that the transformation one undergone in the sphere of professional work often bears adverse consequences for the sphere of workers＇ personal lives and this should be a significant scientific research field.

An Investigation of Samoan Student Experiences in Two Homework Study Groups in Melbourne

This research examines Samoan student experiences in two Homework Study Groups （HSGs） in Melbourne using a researcher-practitioner approach. It highlights that school teachers need to acknowledge students＇ preferred learning methods, especially those of minority backgrounds like the Samoan participants in this investigation. A detailed exploration of the experiences of students in two HSGs finds that while students and their families place a high priority on learning, their cultural practices are not compatible with standard Western learning approaches. The HSGs provided a social space in which students could ask the teacher questions without fear of appearing foolish, in which they could apply themselves to study. It provided a physical study space away from the demands some Samoan families place on their young people, and it provided a cultural space in which the students could learn according to fa＇aSamoa （traditional values and beliefs）. This research makes a contribution to an understanding of the motivations of Melbourne-based Samoan students to learn, of what concerns them, and of impediments to their educational success. It also offers insight into the benefits that set up a specific space for students offers, when its specific intent is influencing the merging of Samoan and Western ideas to further learning.

Trends on Rural Household Net Income Structure Based on Surveys of Baoding Villages from 1930-1998

Using the rural survey data preserved by the Chinese Academy of Social Sciences＇ （CASS） Institute of Economics, this paper analyzes changes in the level and structure of per capita net income in the eleven villages of Baoding Prefecture, Hebei province, over the 1930-1997periods. According to the surveys, per capita net income level of the villages maintained consistent growth, as indicated by survey data on the years of 1930, 1936, 1957, 1986 and 1997, except for 1946 which saw decline, and enjoyed rapid growth particularly in the years of reform and opening-up after 1986. The changes reflect the national trendsustained decline of the proportion of net income from household operations versus eontinuous growth of the proportion wages income takes of the whole income.
