The Cuban health care system and factors currently undermining it.

Science.gov (United States)

Nayeri, K

1995-08-01

This paper explores the dynamics of health and health care in Cuba during a period of severe crisis by placing it within its economic, social, and political context using a comparative historical approach. It outlines Cuban achievements in health care as a consequence of the socialist transformations since 1959, noting the full commitment by the Cuban state, the planned economy, mass participation, and a self-critical, working class perspective as crucial factors. The roles of two external factors, the U.S. economic embargo and the Council of Mutual Economic Cooperation (CMEA), are explored in shaping the Cuban society and economy, including its health care system. It is argued that the former has hindered health efforts in Cuba. The role of the latter is more complex. While the CMEA was an important source for economic growth, Cuban relations with the Soviet bloc had a damaging effect on the development of socialism in Cuba. The adoption of the Soviet model of economic development fostered bureaucracy and demoralization of Cuban workers. As such, it contributed to two internal factors that have undermined further social progress including in health care: low productivity of labor and the growth of bureaucracy. While the health care system is still consistently supported by public policy and its structure is sound, economic crisis undermines its material and moral foundations and threatens its achievements. The future of the current Cuban health care system is intertwined with the potentials for its socialist development.

State of malnutrition in Cuban hospitals.

2005-04-01

We assessed the current state of undernutrition as observed in 1905 patients hospitalized in 12 Cuban health care institutions, as part of a Latin American, multinational survey similar in design and goals. We surveyed 1905 randomly selected patients from 12 Cuban hospitals in a two-phase study. Patients' clinical charts were audited in phase 1, the Subjective Global Assessment was used to assess patients' nutritional status in phase 2. The study was locally conducted by a properly trained team. The frequency of undernutrition in Cuban hospitals was 41.2% (95% confidence interval = 38.9 to 43.4), and 11.1% of patients were considered severely undernourished. Statistically significant (P hospital services/specialties were identified: geriatrics (56.3%), critical care (54.8%), nephrology (54.3%), internal medicine (48.6%), gastroenterology (46.5%), and cardiovascular surgery (44.8%). Malnutrition rates increased progressively with prolonged length of stay. A high malnutrition rate was observed among participating hospitals. The design and inception of policies that foster intervention programs focusing on early identification of hospital malnutrition and its timely management is suggested to decrease its deleterious effects on outcomes of health care in the participating hospitals.

Full Text Available Literature can illuminate and extend our understanding of the affect of shame. In this paper, I will use extracts from my fictional works, published and in progress, and other fictional work and poetry by Cuban and Cuban-American exile writers to illustrate some aspects of shaming in relation to the experience of being a Cuban-American migrant in the United States, particularly relative to the sense of exilic nostalgia for the lost homeland. I will also look at how shame is used by the minority culture to control, erode or slow the process of assimilation and to try to maintain the illusion of the superiority of the minority culture.

Anti-HBs in immunized children with cuban hepatitis B vaccine and impact of booster dose after five years

Dahifar, H.; Mousavi, F.; Ghorbani, A.

2008-01-01

Hepatitis B virus infection and associated diseases are a major public health problem. This study was planned to find out the persistence of antibody against hepatitis B surface antigen in Iranian vaccinated children after five years. Anti-HBs titers in a group of healthy good - responder children who were vaccinated with Cuban hepatitis B vaccine in infancy were measured after five years. Children with antibody titers <100 mlU/ml were revaccinated and retested after four weeks. Mean anti-HBs titers in 68 children (29 females, 39 males) were 482.1 mlU/ml at six months after the third dose of primary vaccination and 153 mlU/ml at five years later. Total mean anti-HBs titers in 36 (52.9%) children out of 68 (17 females, 19 males) were 38.3 mlU/ml and 4(5.8%) of 68 children (two of each sexes) had no detectable antibody after five years. Total mean anti-HBs titers in these hypo- responder and non- responder were 774.3 mlU/ml and 625.5 mlU/ml respectively after booster dose. In a group of children, who were immunized with Cuban hepatitis B vaccine from birth, anti-HBS titers fell at 6.5 years of age and almost half of children became hypo responder or no responder and their anti-HBs titers developed secondary rise after booster vaccination. All children showed immunologic memory to a booster dose. (author)

Force interaction and 3D pole movement in double poling.

Science.gov (United States)

Stöggl, T; Holmberg, H-C

2011-12-01

The aim of this study was to analyze double poling using combined kinetic and 3D kinematic analysis at high skiing speeds as regards pole force components, pole angles and pole behavior during the poling and swing phase. The hypothesis was that a horizontal pole force is more predictive for maximal skiing speed (V(max)) than the resultant pole force. Sixteen elite skiers performed a double-poling V(max) test while treadmill roller skiing. Pole forces and 3D kinematics of pole movement at a speed of 30 km/h were analyzed and related to V(max). The duration of the "preparation phase" showed the strongest relationship with V(max) (r=0.87, Pmax) compared with the resultant pole force. Impact force was not related to V(max). At high skiing speeds, skiers should aim to combine high pole forces with appropriate timing of pole forces and appropriate pole and body positions during the swing and poling phase. The emphasis in training should be on the development of specific strength capacities for pole force production and the utilization of these capacities in double-poling training sessions. © 2011 John Wiley & Sons A/S.

Kourafalou, Vassiliki; Androulidakis, Yannis; Le Hénaff, Matthieu; Kang, HeeSook

2017-10-01

Mesoscale anticyclonic eddies along the northern Cuban coast (CubANs) have been identified in the Straits of Florida, associated with the northward shift of the Florida Current (FC) and the anticyclonic curvature of the Loop Current (LC) at the western entrance of the Straits. The dynamics of CubAN eddies and their interaction with the LC/FC system are described for the first time using satellite, drifter and buoy data, and a high-resolution model. It is shown that the evolution of CubANs to the south of the FC front complements the evolution of cyclonic eddies to the north of the FC, advancing previous studies on synergy between FC meandering and eddy activity. Two types of CubAN eddies are characterized: (a) a main anticyclonic cell (type "A") within the core of the LC during retracted phase conditions, associated with the process of LC Eddy (LCE) shedding from an extended LC, and (b) an individual, distinct anticyclonic eddy that is released from the main LC core and is advected eastward, along the northern Cuban coast (type "B"). There are also mixed cases, when the process of LCE shedding has started, so a type "A" CubAN is being formed, in the presence of one or more eastward progressing type "B" eddies. CubAN evolution is associated with an increased mixed layer and weaker stratification of the upper ocean along the eddy's track. The cyclonic activity along the Cuban coast and wind-induced upwelling events also contribute to the evolution and fate of the CubAN eddies.

Emir Hadzikadunic

2015-01-01

Full Text Available This paper examines the complexity of the Iranian foreign policy through the case of Iranian nuclear program. The paper aims to assess foreign policy orientations and compares actions of the last three Iranian presidents, Mohammad Khatami, Mahmoud Ahmadinejad and current Hassan Rouhani in dealing with the international community (IC in pursuing its nuclear program. This assessment would not be complete without reference to the Iranian supreme leader Ali Khamenei who is actual head of the state and the most powerful political authority. This paper also relates Iranian foreign policy expectation to competing theories of international relations to identify the most dominant or the most consistent policy orientation. Its aim is to strengthen realist and power-based explanations that have dominated the discourse on Middle Eastern in general and Iranian foreign policy in particular. In this context, a number of questions will be addressed here. To what extend was Iranian negotiation with the IC over its nuclear program consistent throughout these three presidencies? What has changed, if anything, from Iranian foreign policy perspective and why? Can Iranian foreign policy behavior on this specific topic and in this specific time be explained through any international relations theory? As there are many other questions, so there are many theories to examine and explain true Iranian intentions, those below the surface of declared goals (Hadzikadunic, 2014. The methods employed in answering these questions are largely structured around a chronological account and comparative approach. It is also based on the analysis of foreign policy discourse and the assessment of key decision makers.

An Analysis of Literary Representations of Iranian Men in Diasporic Iranian Literature

Directory of Open Access Journals (Sweden)

Sanaz Fotouhi

2014-02-01

Full Text Available Middle Eastern Muslim men have been historically subjected to stereotypical representations in the West. Although these men are categorically hypervisible for Western audiences as a similar type, among them Iranian men in particular, have been subject to a specific kind of marginalization. Following the 1979 Islamic revolution and the American hostage crisis in Iran, Iranian men and masculinity have become hypervisible as violent and religiously fanatic. While Western discourses of representation contributed greatly to the construction and representation of this specific kind of masculinity which marginalized and stigmatized Iranian men, Iranians themselves, have played a significant role in reaffirming this view. Ironically, contributing most to the reinforcement of this discourse has been Iranian women’s narratives in English in the West, in the form of memoirs and fictional accounts. These popular accounts have played a significant part in marginalizing and emphasizing a hypervisible and stereotypical representation of Iranian men. This paper considers the representation of Iranian men and masculinity as presented through Iranian women’s narratives in the West in English. By drawing on specific narratives and accounts, it examines how socio-political and historical contexts both in the West and in Iran, have led to Iranian women’s representation of Iranian men hypervisibly. Then, through an examination of some narratives by Iranian men, this paper examines how such representations have led to emphasizing the discourse of exclusion and otherness of Iranian men in the West, hampering the actual smooth integration of diasporic Iranian men into their adopted homes.

Rezvani, Zolfaghar; Arjomandi Rad, Farzad; Khodam, Fatemeh

2015-01-21

In the present work, Mg2Al-layered double hydroxide (LDH) intercalated with cubane-1,4-dicarboxylate anions was prepared from the reaction of solutions of Mg(ii) and Al(iii) nitrate salts with an alkaline solution of cubane-1,4-dicarboxylic acid by using the coprecipitation method. The successful preparation of a nanohybrid of cubane-1,4-dicarboxylate(cubane-dc) anions with LDH was confirmed by powder X-ray diffraction, FTIR spectroscopy and thermal gravimetric analysis (TGA). The increase in the basal spacing of LDHs from 8.67 Å to 13.40 Å shows that cubane-dc anions were successfully incorporated into the interlayer space. Thermogravimetric analyses confirm that the thermal stability of the intercalated cubane-dc anions is greater than that of the pure form before intercalation because of host-guest interactions involving hydrogen bonds. The interlayer structure, hydrogen bonding, and subsequent distension of LDH compounds containing cubane-dc anions were shown by molecular simulation. The RDF (radial distribution function), mean square displacement (MSD), and self-diffusion coefficient were calculated using the trajectory files on the basis of molecular dynamics (MD) simulations, and the results indicated that the cubane-dc anions were more stable when intercalated into the LDH layers. A good agreement was obtained between calculated and measured X-ray diffraction patterns and between experimental and calculated basal spacings.

The Cuban Scenario 25 Years after the Fall of the Berlin Wall

Full Text Available This paper examines the situation in Cuba after 25 years of the fall of the Berlin Wall. The Cuban political system has prevailed despite predictions foresaw its imminent end since the soviet-like socialism crumbled in East Europe and then in the USSR itself. Although the end of the cold war led to profound adjustments in the international system, the Cuban model remained almost unchanged; however, a Cuban repaired communism emerged in the nineties. Dollarization of the economy and permission for foreign investment affected the ideological purity as the main basis of the system persisted untouched. Nevertheless, since Raul Castro took over power from his brother Fidel in 2006 expectations for reform have increased. In fact, in 2011 the Sixth Congress of the Communist Party was held and some reforms have been implemented ever since. The paper focuses on the scope of those reforms as there are still many open questions about the future of the Cuban society.

An improved magnet which more easily provides a radially increasing magnetic field, as well as reduced fringe field and requires less power for a given field intensity. The subject invention comprises a pair of spaced, opposed magnetic poles which further comprise a pair of pole roots, each having a pole tip attached to its center. The pole tips define the gap between the magnetic poles and at least a portion of each pole tip is separated from its associated pole root. The separation begins at a predetermined distance from the center of the pole root and increases with increasing radial distance while being constant with azimuth within that portion. Magnets in accordance with the subject invention have been found to be particularly advantageous for use in large isochronous cyclotrons.

Full Text Available Hybridity is the dynamic relationship between local and global factors that push and pull on people and nations. Hybridity is deeply situated in socio-contextual factors, like cultural beliefs, education, and political systems, that aid and hinder a people’s navigation of globalized phenomena. Simply put, hybridity is how people and societies adapt to a changing world. This article examines the case of Cuba in response to hybridity. Specifically, the article’s purpose is to examine ways that the Cuban National Education System impacts how Cubans navigate the global march towards hybridity. The article reports on a focused ethnographic study of a week long education trip to Cuba during February 2013. The ethnography includes over 100 hours of data collection, including semi-structured interviews with 26 Cuban participants. The study uses Freire’s (1970 notion of “humanizing pedagogy” to analyze how the impact of the Cuban National Education System values in the context of Cuba and larger global context. The study found that three values in particular, amor, solidaridad, and conciencia de derechos y response, were deeply embedded in the Cuban National Education System and effect the way that Cubans navigate the complex hybridity that situates their island nation.

The Cuban treefrog, Osteopilus septentrionalis, is native to Cuba, the Bahamas, and the Cayman Islands, and is invasive in areas where it has been introduced and established in the Caribbean as well as Florida. Despite repeated occurrences in several states over many years, it was not believed that Cuban treefrogs had successfully established outside of Florida in the mainland United States. From mid-September to mid-November 2017, we captured and removed 367 Cuban treefrogs in just four surveys in New Orleans, Louisiana. The impacts of this population on native treefrogs in this area is unknown but possibly severe as indicated by the paucity of observations of native treefrogs during our surveys. Eradication of this seemingly established population is improbable, but continued surveys will facilitate learning about the ecology and genetics of this novel population.

Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From 1992 through 2000, the Cuban women's volleyball team achieved top global performance, winning first place in three successive Summer Olympic Games. Describe the kinanthropometric profiles of Cuban women Olympic volleyball champions during 1992-2000 and compare these by position played. Measurements were taken of body composition, somatotype, proportionality and several anthropometric indicators in 41 Cuban women volleyball players, grouped by playing position. All were members of the national team that participated in the Summer Olympic Games in Barcelona (1992), Atlanta (1996) and Sydney (2000). Mean and standard deviations were calculated for all study variables. Analysis of variance was used to compare means for different positions for the variables weight; height; percent adipose, muscle and bone mass; body mass index; and muscle-to-bone ratio. Discriminant analysis was performed to identify anthropometric dimensions differentiating playing positions (center, spiker and setter), using pvolleyball players was balanced mesomorphic (2.7-3.6-2.9). Classified by position, centers (2.9-3.4-3.4) and spikers (2.8-3.6-2.9) presented an average mesomorphic-ectomorphic somatotype, and setters (2.6-3.7-2.6) were balanced mesomorphic. On assessing Somatotype Attitudinal Mean (SAM), centers and spikers showed more intrapositional homogeneity than that of setters. Centers were significantly taller (187.1±2.5 cm) than players in other positions. Centers' percent adipose tissue mass (28.9±2.7%) was significantly higher than that of setters (24.3±2.7%), who were leanest of all positions. The

Full Text Available Cuban musicians active in New  York in the 1860s through the 1890s such as Ignacio Cervantes, Emilio Agramonte, and Rosalia Chalia assisted in the struggle for Cuban independence from Spain from the vantage point of New York's Cuban émigré community, and they also established  a strong  presence in the city's musical life.  Important Mexican musicians such as Miguel Lerdo  de Tejada and Carlos Curti intermittently visited New York or were long-term residents there. This was especially true during the late- nineteenth century, when the forced political stability during the Porfiriato made possible the extended visits of Mexican musicians and ensembles to North American cities such as New York. The Mexican Revolution also sent Mexican musicians to the United States in search of political freedom as well as economic and artistic opportunities that were temporarily closed to them in Mexico.

2013-12-01

Full Text Available The work contribute with some valuations about the conception of the cooperative in the Cuban constitutionalism, with the purpose that the constitution can guide -like it corresponds- the legal implementation of the figure toward an integral perspective. To accomplish this goal, this article offers a characterization of the institution that illustrates about its identity. Then it analyzed the juridical dimension of the cooperative, pondering the different doctrinal postures that have tried to define its nature. Lastly, it argue that the current laws of the Cuban Constitution, influenced by a reduced conception of the institution, suffers some limitations that block the good use of the figure in a socioeconomic context in which it is called to transcend.

Broche-Pérez, Yunier; López-Pujol, Héctor Alejandro

2017-01-01

The diagnostic accuracy of the Cuban version of the revised Addenbrooke's Cognitive Examination (ACE-R) in identifying mild cognitive impairment (MCI) in comparison with the Mini-Mental State Examination (MMSE) was assessed. The Cuban ACE-R was administered to a group of 129 elderly subjects (92 cognitively healthy and 37 subjects with MCI). The t tests for independent samples were used to compare scores of different psychometric scales between groups, and effect sizes (Cohen's d) were calculated. Cronbach's coefficient α was used to evaluate the reliability of psychometric scales. The validity of ACE-R to screen for MCI was assessed by receiver operating characteristic (ROC) curves. The Cuban ACE-R had reliable internal consistency (Cronbach's coefficient α = 0. 879). The optimal cut-off score for ACE-R for detecting MCI was 84/85. The sensitivity and specificity of ACE-R to screen for MCI was superior to those of MMSE. The area under the ROC curve of the Cuban ACE-R was much larger than that of MMSE (0.93 and 0.63) for detecting MCI. The Cuban ACE-R is a valid screening tool for detecting cognitive impairment. It is more sensitive and accurate in screening for MCI than MMSE. © 2018 S. Karger AG, Basel.

2005-01-01

We reevaluate the taxonomic status of the Cuban population of the Common Black-Hawk (Buteogallus anthracinus) based on our examination of additional specimens, nests, eggs, and voice data. Buteogallus a. gundlachii is smaller than mainland populations of anthracinus and differs from mainland birds in plumage coloration and pattern. The common (alarm) call of gundlachii is a series of three or four notes, differing from that of mainland anthracinus, whose call consists of 9-24 notes. In the Isla de Pinos, Cuba, we observed gundlachii eating two species of land crabs (71.4%), centipedes (7.1%), lizards (10.7%), mammals (7.1%), and a bird (3.6%). We consider Buteogallus gundlachii Cabanis 1854 (1855), the Cuban Black-Hawk, to be a full species, endemic to Cuba, Isla de Pinos, and many of the cays of the Cuban Archipelago. ?? 2005 The Raptor Research Foundation, Inc.

Prendas-Ngangas-Enquisos: turbulence and the influence of the dead in Cuban-Kongo material culture.

Science.gov (United States)

Ochoa, Todd Ramón

2010-01-01

Cuban-Kongo praise of the dead in Havana turns insistently around complex agglomerations of materials called "prendas,"ngangas," and "enquisos." This article addresses the ontological status of "prendas-ngangas-enquisos," which practitioners of Cuban-Kongo affliction practices care for as entities that determine the very possibility of their healing and harming craft. Cuban-Kongo societies of affliction, in Havana collectively referred to as "Palo," stake their claim to influence others in and through these entities. In this essay I seek to position the influence generated in prendas-ngangas-enquisos as a problem for Euro-American materialism, to be addressed not through symbolic or representational solutions but, rather, by refocusing the problem itself via alternate distributions of its epistemological, historical, and ethnographic elements. Contextualized within ethnographic description, I first propose that prendas-ngangas-enquisos do not conform to dialectical logic, and should thus be positioned conceptually as something other than "objects" or "fetishes." From there, I consider Creole turns on the term prenda and explore scholarly accounts of 19th-century Cuban slavery and manumission, which I place alongside what is known about pawn slavery among BaKongo people prior to and during the Atlantic slave trade. Having established a basic series of conceptual and historiographic coordinates, I then suggest ethnographically how prendas-ngangas-enquisos come to command others, thereby guaranteeing Cuban-Kongo healing and harming sovereignty in Cuba today.

In the social development, this constitutes a great problem in the formation of the individuals to who, the social relationships allow them to value, to transform the reality and to be educated, what leads to the formation of the personality. The Cuban universities, as entities open to the society, win more and more partisans in the conception that their purpose is not only to transmit knowledge in its closed environment, but on the contrary, they represent a main socialized agent of education in values aware of the social mission that has given to it by the society that is built, like a formative institution able to solve the necessities of the society. For that reason, it is demanded the integral formation of the professionals. In the work it is approached the education in values from the perspective o the current Cuban society necessities that demands the development of a humanist pedagogy sustained in axiological bases that defend a new pedagogic ethics. It is carried out an analysis of the socialized agencies and the agents in charge of this process, as well as the historical antecedents of the education in values from the Cuban point of view in the different contexts the topic has been studied, as well as the contributions from the Cuban pedagogy to the development of it, indispensable from the integral formation of the Physical Culture professionals.

At the modern age, to acquire knowledge and experience, the individuals with their own specific culture have to enter contexts with cultural diversity, adapt to different cultures and have social interactions to be able to have effective inter-cultural relationships.To have such intercultural associations and satisfy individual needs in the society, cultural intelligence and social adaptability are deemed as inevitable requirements, in particular for those who enter a quite different culture. Hence, the present study tries to compare the cultural intelligence and its aspects and social adaptability in Iranian and non-Iranian dormitory students of Isfahan University of Medical Sciences in 2012. The study was of descriptiveanalytical nature. The research population consisted of Iranian and non-Iranian students resided in the dormitories of Isfahan University of Medical Sciences which are 2500, totally. For Iranian students, two-stage sampling method was adopted. At the first stage, classified sampling and at the second stage, systematic random sampling was conducted. In this way, 441 students were selected. To form non-Iranian students' sample, consensus sampling method was applied and a sample of 37 students were obtained. The research data was collected by using Earley & Ang's Cultural Intelligence Questionnaire with the Cronbach's coefficient α of 76% and California Social Adaptability Standard Questionnaire with the Cronbach's coefficient α of over 70%. Then, the data were put into SPSS software to be analyzed. Finally, the results were presented by descriptive and inferential statistics methods. The study findings revealed that there was no statistically significant difference between cultural intelligence and cognitive aspect of cultural intelligence in Iranian and non-Iranian students (P≥0/05). However, Iranian and non-Iranian students statistically differed in terms of the following aspects of cultural intelligence: meta-cognitive aspect (61.8% for

Full Text Available Teaching English in an Iranian and Islamic culture poses complex questions for both teachers and learners. In this paper, the authors intend to shed light on what it means to teach English as a foreign language (TEFL in an Islamic-Iranian context. Having reviewed the colonial and postmodern views of English language teaching, the authors took a look beyond the current state of TEFL in Iran, which is marked by its continuing global tendency, and into the future with an emphasis on the importance of including the local specificities of the Iranian culture and religion. The status of the TEFL in Iran and the direction it should take in the future are accompanied by offering some solutions to inherent problems. Iranian TEFL is introduced as the successful assertion of Iranian local culture against the cultural and ideological domination of the West, which can be an antidote to the harshness of all marginalizations Iranians have suffered for centuries.

The Cuban Regulatory Authority is carrying out a National Program for fostering and development of Safety Culture taking into account the wide recognition of the Human factors contribution to radiological events. The program includes the introduction of new regulatory practices and initiatives in order to increase the safety culture in Cuban facilities. The most recent of those initiatives is the System for Radiological Event Analysis, Dissemination and Learning, called ADASIR (Initials of the System's name in Spanish). The main purpose of this system is to provide a better understanding and knowledge of any radiological event reported both in the country and abroad reducing, this way, the possibility of a new occurrence of a similar event in our facilities. A team of regulatory and external experts make together a detailed review of all available information about the event and identify possible root causes, failed barriers and other important data of national interest. The results of such review are documented and sent to any Cuban facility or organization with potential for similar occurrence according to the equipment and practices they have. The document includes an specific checklist which could be used by the facilities to make a self-assessment and evaluate theirs strength and weakness in regards to a similar event. This paper presents the main characteristics and results of this new experience of Cuban Regulatory Authority. (author)

While this phenomenon has attracted scholarly attention for some time, the literature has grown particularly rapidly in recent years. It is, perhaps, not entirely fortuitous that a spate of current academic publications on the subject coincided with a scramble by the popular media to exploit its exotic potential in the context of the 1993 U.S. Supreme Court case on animal sacrifice. Clearly, what has come to be called an Afro-Cuban "cultic renaissance" in exile holds promise both for sensationalist journalism and certain kinds of theoretical projects.

Chaban, Vitaly V.; Andreeva, Nadezhda A.

2017-12-01

Energy generation and storage are at the center of modern civilization. Energetic materials constitute quite a large class of compounds with a high amount of stored chemical energy that can be released. We hereby use a combination of quantum chemistry methods to investigate feasibility and properties of carbon-nitrogen cubanes and multi-charged polynitrogen cations in the context of their synthesis and application as unprecedented energetic materials. We show that the stored energy increases gradually with the nitrogen content increase. Nitrogen-poor cubanes retain their stabilities in vacuum, even at elevated temperatures. Such molecules will be probably synthesized at some point. In turn, polynitrogen cations are highly unstable, except N8H+, despite they are isoelectronic to all-carbon cubane. Kinetic stability of the cation decays drastically as its total charge increases. High-level thermodynamic calculations revealed that large amounts of energy are liberated upon decompositions of polynitrogen cations, which produce molecular nitrogen, acetylene, and protons. The present results bring a substantial insights to the design of novel high-energy compounds.

Massage Therapy in Iranian Traditional Medicine

2012-10-01

Full Text Available Background and Aim: Massage training and how the body is influenced by massage are common issues which are seriously under study and discussion in Iranian traditional medicine. Iranian physicians considered motion and massage as major principles of health maintenance.In this study, we examined the available literature of traditional medicine to evaluate location, purpose and use of massage therapy in Iranian medicine in comparison with other popular conventional styles.The aim of Iranian massage is to regulate the core body temperature and aid to eliminate the waste products from the body. This type of massage is divided into five categories including solid, soft, moderate, great and aggressive, based on the intensity, speed, duration and techniques of massage.Iranian physicians proposed general body massage or massage of a particular area based on subjective complaints. They recommended specific massages in particular groups including children, pregnant women, the elderly and athletes. In some cases, the effects of these recommendations have been studied in clinical trials.Conclusion: It seems that the major difference between Iranian massage and other styles of massage is special attention of Iranian massage to the individual circumstances, and the cause of the problem rather than technique of the massage.

This paper examines the history, methods, costs, and future prospects of Cuba's attempts to develop the energy potential of sugarcane. An overview of the main factors affecting the current sugarcane agro-industry in Cuba is provided, along with an analysis of why, despite attempts by the Cuban government to revive the country's sugarcane agro-industry, the industry continues to decline. The prevailing conditions and degree of modernization in Cuban sugar factories are evaluated. The sugar-agro industry's main production bottlenecks are studied.

In elite cross-country skiing, double poling is used in different terrain. This study compared O 2 -cost and kinematics during double poling with four different pole lengths [self-selected (SS), SS - 5 cm, SS + 5 cm, SS + 10 cm] at Low versus Moderate incline. Thirteen highly trained male cross-country skiers (mean ± SD 23 ± 3 years; 182 ± 4 cm; 77 ± 6 kg) completed eight submaximal trials with roller skis on a treadmill at two conditions: "Low incline" (1.7°; 4.5 m s -1 ) and "Moderate incline" (4.5°; 2.5 m s -1 ) with each of the four pole lengths. O 2 -cost and 3D body kinematics were assessed in each trial. In Low incline, SS + 10 cm induced a lower O 2 -cost than all the other pole lengths [P size (ES) 0.5-0.8], whereas no differences were found between the remaining pole lengths (P > 0.05; ES 0.2-0.4). In Moderate incline, significant differences between all pole lengths were found for O 2 -cost, with SS - 5 cm > SS > SS + 5 cm > SS + 10 cm (P differences in O 2 -cost between SS and the other pole lengths were greater in Moderate incline than Low incline (SS - 5 cm; 1.5%, ES 0.8, SS + 5 cm; 1.3%, ES 1.0, and SS + 10 cm; 1.9%, ES 1.0, all P difference was found in cycle, poling or reposition times between pole lengths. However, at both conditions a smaller total vertical displacement of center of mass was observed with SS + 10 cm compared to the other pole lengths. Increasing pole length from SS - 5 cm to SS + 10 cm during double poling induced lower O 2 -cost and this advantage was greater in Moderate compared to Low incline.

One of the main elements of economic sanctions against Iran due to its nuclear and military programs is crude oil exportation restrictions in addition to investment in Iranian energy related projects. Senders of such sanction are interested in understanding the impacts of such embargos on international oil prices. We apply unrestricted vector autoregressive (VAR) model, using impulse response functions (IRF) and variance decomposition analysis (VDA) tools with annual data from 1965 to 2012 to analyze the dynamic response of international oil prices to Iranian oil export sanction. Controlling for the supply of non-Iranian oil, the world GDP per capita, and post-Islamic revolution exogenous dummy variables, we show that international oil prices respond negatively and statistically significant to increasing shock in absolute negative changes of the Iranian oil exports – our proxy of Iran oil sanctions – following the first 2 years after shock. The main reason is the positive response of the non-Iranian oil supply to negative shocks in Iranian oil exports, filling the missing supply of Iranian oil in international markets. - Highlights: • We analyze the interconnections between Iranian oil supply and global oil prices. • We use VAR modeling and annual data from 1965 to 2012 for the case of Iran. • There are no inflationary effects of Iranian oil sanction on world oil prices. • Non-Iranian oil supply offsets the missing Iranian oil in the market

Hsu, John S.

2010-05-18

A method and apparatus in which a stator (11) and a rotor (12) define a primary air gap (20) for receiving AC flux and at least one source (23, 40), and preferably two sources (23, 24, 40) of DC excitation are positioned for inducing DC flux at opposite ends of the rotor (12). Portions of PM material (17, 17a) are provided as boundaries separating PM rotor pole portions from each other and from reluctance poles. The PM poles (18) and the reluctance poles (19) can be formed with poles of one polarity having enlarged flux paths in relation to flux paths for pole portions of an opposite polarity, the enlarged flux paths communicating with a core of the rotor (12) so as to increase reluctance torque produced by the electric machine. Reluctance torque is increased by providing asymmetrical pole faces. The DC excitation can also use asymmetric poles and asymmetric excitation sources. Several embodiments are disclosed with additional variations.

Menorrhagia is a common problem. Medical management for menorrhagia includes hormonal and nonhormonal treatments. These treatments have different side effects, which reduce quality of life. Complementary and traditional medicines have been used to handle menorrhagia for centuries in many cultures. There is a lot of information and data in Iranian traditional documents or books about medicinal herbs that are used by Iranian traditional medicine scientists for the treatment of menorrhagia. The aim of this study was to review the approaches to menorrhagia in Iranian traditional medicine texts. In this study, some main Iranian traditional medicine manuscripts including Canon of Medicine and Al-Havi of Rhazes were studied to extract important information about menorrhagia management. Iranian traditional medicine physicians have relied on an organized system of etiological theories and treatments for menorrhagia. Their methods for menorrhagia management may be able to convince the desire of many women to preserve their uterus and avoid hormonal therapy. © The Author(s) 2015.

Morphological measurements and body indices for Cuban Creole goats and their crossbreds

Full Text Available In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula and Canary Islands. The crossbreds were more varied, mostly due to undesigned disorganized crossing. These data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the Cuban Creole goat.

We develop the Tree-Loop Duality Relation for two- and three-loop integrals with multiple identical propagators (multiple poles). This is the extension of the Duality Relation for single poles and multi-loop integrals derived in previous publications. We prove a generalization of the formula for single poles to multiple poles and we develop a strategy for dealing with higher-order pole integrals by reducing them to single pole integrals using Integration By Parts.

In situ characterization of cofacial Co(IV) centers in Co4O4 cubane: Modeling the high-valent active site in oxygen-evolving catalysts.

The Co 4 O 4 cubane is a representative structural model of oxidic cobalt oxygen-evolving catalysts (Co-OECs). The Co-OECs are active when residing at two oxidation levels above an all-Co(III) resting state. This doubly oxidized Co(IV) 2 state may be captured in a Co(III) 2 (IV) 2 cubane. We demonstrate that the Co(III) 2 (IV) 2 cubane may be electrochemically generated and the electronic properties of this unique high-valent state may be probed by in situ spectroscopy. Intervalence charge-transfer (IVCT) bands in the near-IR are observed for the Co(III) 2 (IV) 2 cubane, and spectroscopic analysis together with electrochemical kinetics measurements reveal a larger reorganization energy and a smaller electron transfer rate constant for the doubly versus singly oxidized cubane. Spectroelectrochemical X-ray absorption data further reveal systematic spectral changes with successive oxidations from the cubane resting state. Electronic structure calculations correlated to experimental data suggest that this state is best represented as a localized, antiferromagnetically coupled Co(IV) 2 dimer. The exchange coupling in the cofacial Co(IV) 2 site allows for parallels to be drawn between the electronic structure of the Co 4 O 4 cubane model system and the high-valent active site of the Co-OEC, with specific emphasis on the manifestation of a doubly oxidized Co(IV) 2 center on O-O bond formation.

Social workers’ construction of “family” in Cuban context: Ideas for a debate

Angela Isabel Peña Farias

2015-12-01

Full Text Available This paper presents preliminary research about the process of the construction of concepts in social work. In this case, it is referred to as a social worker’s construction of “family” as a concept and as a field of practice in a current Cuban context. Based on an exploratory and qualitative research design, the paper presents an analysis that also opens to the discussion about social work with families in Cuba. The findings shows that Cuban social workers think of family as a group with cohabitation and affinity, which is more important than consanguinity, as a dimension for family definitions. They also point at structures of family, special bonds in family network and the social internal and external functions of family in their definitions. Among these functions, the transmission of cultural values, as well as the emotional support and shelter for members, seems relevant.Regarding family as a field of practice, they all share the criteria that is necessary for practice to develop a contextual analysis of each situation that goes from macro-contextual aspects to the micro-reality of family. The importance of structural matters and their impact on family functions is also a common idea, which is nucleated around a multigenerational reality of Cuban families and evaluated as a positive or negative impact depending on the case in question.They consider social work with families, and social work in general, to be in a critical situation in relation to losing professionalization and social recognition. The reasons explaining these ideas have to do with the instability of social work institutionalization and the recent retraction of social services. These variations have obeyed the changes in a Cuban context that affects the entire welfare system and social work’s position in it.

2018-01-01

Full Text Available AC (alternating current system backup protection setting calculation is an important basis for ensuring the safe operation of power grids. With the increasing integration of modular multilevel converter based high voltage direct current (MMC-HVDC into power grids, it has been a big challenge for the AC system backup protection setting calculation, as the MMC-HVDC lacks the fault self-clearance capability under pole-to-pole faults. This paper focused on the pole-to-pole faults analysis for the AC system backup protection setting calculation. The principles of pole-to-pole faults analysis were discussed first according to the standard of the AC system protection setting calculation. Then, the influence of fault resistance on the fault process was investigated. A simplified analytic approach of pole-to-pole faults in MMC-HVDC for the AC system backup protection setting calculation was proposed. In the proposed approach, the derived expressions of fundamental frequency current are applicable under arbitrary fault resistance. The accuracy of the proposed approach was demonstrated by PSCAD/EMTDC (Power Systems Computer-Aided Design/Electromagnetic Transients including DC simulations.

Iranian Democratization Part I: A Historical Case Study of the Iranian Green Movement

Victor H. Sundquist

2013-01-01

Full Text Available The 2009 Iranian Presidential Elections represented one of the most contentious displays of the evolving Iranian democracy since the 1979 Islamic Revolution that led to the removal of Mohammad Reza Shah Pahlavi – the nation’s last shah. This tumultuous political event not only exposed a growing rift between the political and religious ruling elite in that country; it also led to the emergence of an opposition movement that would later be known as the Green Revolution. Viewed through a Western political lens, this revolution represented yet another opportunity for the demise of the ruling Iranian Islamic Regime. Recently, some scholars have questioned whether this movement was ever intended to topple the government in the first place, and have argued instead that it represented the beginning of a long-term civil rights push. To better understand why the Green Movement emerged one must first understand what the original intent of the movement was, as well as the political factors that led to its rapid growth. In order to answer these questions, this article will compare and contrast identified similarities and differences between the 1979 Islamic Revolution and 2009 Green Movement in order to isolate the true intent behind this perceived Iranian political revolt.

Polyphony in Iranian Music

2017-08-01

Full Text Available Although Iranian regional music, like Iranian traditional[*] music, is basically monophonic and follows the rules of heterophony, we occasionally run across polyphonic pieces, although most have been unwittingly formed as such. This study shows that these polyphonic pieces could be found in the following forms: 1. The meeting of two vocal parts, where the second singer starts singing before the melody is completed by the first. 2. Imitations, as a result of singing the same melody by a few singers who consecutively start singing with some delay between their parts. 3. Simultaneous playing of variants of the same melody by two players (variant heterophony. 4. Changing between the soloist and the chorus (in the responsorial form or between one chorus and another (in an antiphoner[**] where a chorus begins the next part of the lyrics before the soloist or the other chorus is finished with their own part. 5. Polyphony resulting from the playing of a melody by a few singers where each singer sings the melody based on their own voice register depending on their physiological features. 6. Accompanying the first singer using alternate changes to the drone note or following the up-going or down-going movement of the melody in playing the tamira (in Lorestan, the dotār (in Khorasan and tamderā (in Turkman leads to the conscious parallelism of two voices. The radif of traditional music and the Iranian regional music, like those of other Middle East countries, is monophonic and follows the forms of heterophony; that is, the same melody is played and changed by two or more players. The change of a specific melody by two players, or a player and a singer, sometimes leads to the simultaneous playing of two different notes. Such an interference or combination of two sounds is a matter of heterophony, and by no means of harmony or accord. Interference of notes or combinations of notes in heterophony are not predictable. Since the melody is played extempore

Creating a safety culture in the regulatory authority: The Cuban experience

Ferro Fernandez, R.; Guillen Campos, A.

2002-01-01

The Cuban regulatory authority has been working during several years for the fostering and development of a high Safety Culture level in nuclear activities in the country. As starting point to achieve this objective the assessment of the Safety Culture level in the regulatory authority performance was considered an important issue. For this purpose a preliminary diagnosis was carried out by means of a national survey that allowed identifying some areas of the regulatory activity that required improvements in order to achieve a higher Safety Culture and to immediately implement appropriate actions. Two of the most important actions undertaken were: the statement of the regulatory authority Safety Policy which governs and determines the performance of this organization and its staff and also the implementation of a new interaction practice at top level between the regulatory authority and the utilities of the nuclear sector through the Annual Regulatory Conference. The present paper summarizes these two introduced practices into the Cuban regulatory activity. (author)

‘La Comida Mambisa’: food, farming, and Cuban identity, 1839-1999

Shannon Lee Dawdy

2002-01-01

Full Text Available Describes how Cuba developed a countrywide system of food meaning and production in the mid-19th c. that became a national, and eventually "nationalist", cuisine during Cuba's revolutionary moments. Author explains how the centrality of food within Cuban national identity was strongly related with the valency associated with the subsistence farming on small family farms ("sitios", producing these native foods and Caribbean ingredients, e.g. cassava, guava, and sweet potatoes. The self-sufficiency of these small farmers was in emerging nationalist discourses opposed to the large-scale, export-oriented, colonial plantations and to slavery. Many small family farmers, of which many were ex-slaves, participated in the armed struggles in part to defend their right of independent, subsistence agriculture. Author outlines how since the early, mid-19th-c. Creole nationalism, Creole food and the small farms remained associated with authentic Cuban folk culture and with national identity, and related to independence struggles, and self-sufficiency, including during and after the 1959 Revolution.

[Mo{sub 3}S{sub 4}(H{sub 2}O){sub 9}]{sup 4+} has been prepared and supported on zeolites H-USY and NaY. Using this cluster as a precursor for HDT catalysts has many advantages: it is cationic, already in a sulfided form, and a promoter such as a second metal M' such as Cu, Ni or Pd can be incorporated to form Mo{sub 3}M'S{sub 4}{sup 4+}. The cubane structure was found unchanged after loading in the case of NaY (EXAFS, XPS) and although TEM showed that Mo was mainly on the outer surface of the zeolite crystals, DRX confirmed that a modification of the counter ion also occurred, and an isotherm was obtained with NaY zeolite. A thermal stability study was led under N{sub 2} and a mixture of H{sub 2}/H{sub 2}S to optimize the pretreatment of the catalysts. Those were subsequently pre-sulfided and tested in toluene hydrogenation and their activities with both types of zeolites turned out to be the same or even better than that of catalysts prepared by the classical route. An application to mixed cubane-type structures is also reported. (author)

2008-01-01

Full text: In the frame of a national research project supported by the Nuclear Energy Agency of the Ministry of Science, Technology and Environment of the Republic of Cuba doses received by Cuban population due to the exposure to existing in the environment sources of radiation were assessed. Direct measurements of sources representing 90% of average total doses to world population according to UNSCEAR data were made and estimations of doses were obtained for the different components of the total dose: doses due to the exposure to cosmic radiation, external terrestrial radiation, potassium contained in human body and inhalation and ingestion of radionuclides present in the environment. Using the obtained results it was made an estimation of total doses to Cuban population due to environmental radiation sources and the contributions of different dose components were assessed. This was carried out through a Monte Carlo simulation of the total doses using the parameter of dose distributions obtained for the different contributors (components) to total dose. On the basis of the estimations the average total effective dose to Cuban population due to the exposure to environmental sources was estimated as 1.1 ± 0.3 mSv per year. This low dose value is in the range of doses estimated by UNSCEAR for world population due to natural background and can be explained by the specific of Cuban environment: a majority of the population living at the sea level or at low altitudes, relative low content of primordial radionuclides in soils and high ventilation rates in dwellings. All the instructions specified in the Call for Abstracts should be taken into account. e/ 41 and 457. (author)

Acute liver failure is rare in pediatric patients and is one of the most challenging medical emergencies due to its prognostic and therapeutic implications. The best scientific evidence worldwide comes from multicenter studies in developed countries. In Cuba, there are no prior studies of this disorder in children. Describe the main clinical features of Cuban children treated at a national referral center for acute liver failure, as defined by recognized diagnostic criteria for pediatric patients. A case series study was conducted comprising patients diagnosed with acute liver failure treated from 2005 to 2011 in the hepatology and liver transplant service at Havana's William Soler University Children's Hospital. Variables were age group, etiology of acute liver failure, grade of hepatic encephalopathy, blood chemistry variables, and clinical outcome (whether or not spontaneous recovery of liver function occurred). Associations between variables were assessed using contingency tables, and case fatality was calculated, as well as relative risk with its 95% confidence interval. The Mann-Whitney U test was used to compare means of laboratory test results. Median age of the 31 patients studied (14 boys and 17 girls) was 24 months (range 1-180). Time between symptom onset and diagnosis of acute liver failure was 25.1 days (SD 16.8). Infection was the most common etiology, present in 61.3% of cases (19/31); nonhepatotropic viruses, especially cytomegalovirus, predominated in infants. Spontaneous recovery occurred in 15 patients (48.4%), 3 (9.7%) received transplants, and 13 died, for a case fatality of 41.9%. Outcome was not associated with etiology (p = 0.106), but was statistically associated with degree of hepatic encephalopathy (p failure in Cuban children calls for further epidemiologic study and identification of local underlying determinants of this phenomenon.

The sublimation enthalpy of cubane, a key reference material for force field and quantum mechanical computations, was measured by combining the vaporization enthalpy at T = 298.15 K to the sum of the fusion enthalpy measured at T = 405 K and a solid-solid phase transition that occurs at T 394 K. The fusion and solid-solid phase transitions were measured previously. A sublimation enthalpy value of (55.2 ± 2.0) kJ mol -1 at T = 298.15 K was obtained. This value compares quite favorably the value obtained by comparing the sublimation enthalpy of similar substances as a function of their molar masses but is at odds with earlier measurements

"Nation or death": the Cuban Revolution and the 1990’s crisis.

Directory of Open Access Journals (Sweden)

Julian Araujo Brito

2012-05-01

Full Text Available This article aims to analyze the survival conditions of the cuban political regime from the end of the cold war, during the “Special Period”. The breakdown of the socialist bloc between 1989 and 1991 certainly represented an important change of direction for the Cuban Revolution and generated an economic crisis of great proportions, which put at risk the very permanence of the revolutionary regime. However, it was allowed to survive - despite the diffi cult inner and outer conditions and the frequent contrary predictions – to its most delicate moment since the origin in 1959. Although there was a plan for economic reforms and policies to a lesser extent, the survival of the regime was bounded to its nationalistic appeal, what was the political legitimacy before the socialism crisis, as well as the defense of the social achievements of the 30 years of the revolutionary regime.

Iranians and Their Pride: Modalities of Political Sovereignty

Science.gov (United States)

Moaddel, Mansoor

In 2000, we asked a nationally representative sample of 2,532 Iranian adults "which of the following best describes you: I am an Iranian, above all; I am a Muslim, above all; I am an Arab, a Kurd, a Turk, a Baluch, etc., above all?" We also asked them how proud they are to be Iranian; (1) very proud, (2) proud, (3) not proud, and (4) not proud at all. In the 2005 survey of a nationally representative sample of 2,667 Iranian adults, we asked these questions again. The first question was intended to measure national identity and the second national pride. The results showed that between the two surveys the percent of Iranians who defined themselves as "Iranians, above all" went up significantly-from 35% in 2000 to 42% in 2005. Those who said that they were very proud to be Iranian, on the other hand, went down considerably-from 89% in 2000 to 64% in 2005. What is more, national identity and national pride displayed opposing relationships with the norms and values that were rigorously promoted by Iran's religious regime and these relationships grew stronger between 2000 and 2005. The feeling of national pride was positively linked to attitudes toward gender inequality, religiosity, and religious intolerance, but negatively to attitudes toward the West, while national identity had just the opposite relationships with these variables.

Facial anthropometric measurement is considered an essential concern of surgeons, orthodontists, artists and forensic scientists. The aim of this study is to investigate facial anthropometric norms of the young Iranian population. The study participants consisted of 200 healthy Iranian students (100 males, 100 females) aged 18-25 years old. Twenty-three liner and four angular measurements were investigated twice by a dentist. Independent-samples t test was used to compare indices between males and females and also between countries. A p value less than 0.05 was considered statistically significant. It was found that the mean measurements of c'-sn' of both sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were statistically greater in Iranian males than in females ( p  < 0.05). Comparing Iranian anthropometric norms with North American Whites, Malays, Turkish and African American women demonstrated that there were statistically significant differences in most anthropometric measurements between Iranians and other populations ( p  < 0.05). In Iranians, mean measurements of c'-sn' of the right and left sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were greater in men than in women. Comparing Iranian males and females with different ethnicities indicated several interracial differences, which should be taken into consideration when dealing with patients or also practitioners originated in this region.

Requirements to cuban reinforcing steel under seismic demand; Exigencias al acero de refuerzo cubano ante la demanda sismica

The behaviour of steel manufactured according to the Cuban standard NC 7:02 is studied, in order to evaluate about the conformance to requirements of the seismic design. Steel bars of Grade G-40 and G-60, of all commercial diameters between 10 and 32 mm, were test with this purpose. An experimental program was developed, that include dimensional verifications, tensile testing, ben and rebend, hardness testing and chemical composition tests. The results showed that steel bars satisfy geometric and tensile requirements of Cuban standard, however, some tested samples fulfill the demands that establish some codes about the required ductility to adequate perform of building of reinforced concrete where prevalence the earthquake. Conclusions about the necessity to consider in the future Cuban standard, special requirements to steel that assist the necessities of the earthquake engineering. Proposals are suggested to guarantee the ductile behaviour of the steel of national production. (Author)

Analysis of policy implications and challenges of the Cuban health assistance program related to human resources for health in the Pacific

Asante Augustine D

2012-05-01

Full Text Available Abstract Background Cuba has extended its medical cooperation to Pacific Island Countries (PICs by supplying doctors to boost service delivery and offering scholarships for Pacific Islanders to study medicine in Cuba. Given the small populations of PICs, the Cuban engagement could prove particularly significant for health systems development in the region. This paper reviews the magnitude and form of Cuban medical cooperation in the Pacific and analyses its implications for health policy, human resource capacity and overall development assistance for health in the region. Methods We reviewed both published and grey literature on health workforce in the Pacific including health workforce plans and human resource policy documents. Further information was gathered through discussions with key stakeholders involved in health workforce development in the region. Results Cuba formalised its relationship with PICs in September 2008 following the first Cuba-Pacific Islands ministerial meeting. Some 33 Cuban health personnel work in Pacific Island Countries and 177 Pacific island students are studying medicine in Cuba in 2010 with the most extensive engagement in Kiribati, the Solomon Islands, Tuvalu and Vanuatu. The cost of the Cuban medical cooperation to PICs comes in the form of countries providing benefits and paying allowances to in-country Cuban health workers and return airfares for their students in Cuba. This has been seen by some PICs as a cheaper alternative to training doctors in other countries. Conclusions The Cuban engagement with PICs, while smaller than engagement with other countries, presents several opportunities and challenges for health system strengthening in the region. In particular, it allows PICs to increase their health workforce numbers at relatively low cost and extends delivery of health services to remote areas. A key challenge is that with the potential increase in the number of medical doctors, once the local students

Digitizing dissent: cyborg politics and fluid networks in contemporary Cuban activism

Directory of Open Access Journals (Sweden)

Samuel Kellogg

2016-06-01

Full Text Available Communication technologies shape how political activist networks are produced and maintain themselves. In Cuba, despite ideologically and physically oppressive practices by the state, a severe lack of Internet access, and extensive government surveillance, a small network of bloggers and cyberactivists has achieved international visibility and recognition for its critiques of the Cuban government. This qualitative study examines the blogger collective known as Voces Cubanas in Havana, Cuba in 2012, advancing a new approach to the study of transnational activism and the role of technology in the construction of political narrative. Voces Cubanas is analyzed as a network of connections between human and non-human actors that produces and sustains powerful political alliances. Voces Cubanas and its allies work collectively to co-produce contentious political discourses, confronting the dominant ideologies and knowledges produced by the Cuban state. Transnational alliances, the act of translation, and a host of unexpected and improvised technologies play central roles in the production of these narratives, indicating new breed of cyborg sociopolitical action reliant upon fluid and flexible networks and the act of writing. 

Geometric Modelling of Octagonal Lamp Poles

Science.gov (United States)

Chan, T. O.; Lichti, D. D.

2014-06-01

Lamp poles are one of the most abundant highway and community components in modern cities. Their supporting parts are primarily tapered octagonal cones specifically designed for wind resistance. The geometry and the positions of the lamp poles are important information for various applications. For example, they are important to monitoring deformation of aged lamp poles, maintaining an efficient highway GIS system, and also facilitating possible feature-based calibration of mobile LiDAR systems. In this paper, we present a novel geometric model for octagonal lamp poles. The model consists of seven parameters in which a rotation about the z-axis is included, and points are constrained by the trigonometric property of 2D octagons after applying the rotations. For the geometric fitting of the lamp pole point cloud captured by a terrestrial LiDAR, accurate initial parameter values are essential. They can be estimated by first fitting the points to a circular cone model and this is followed by some basic point cloud processing techniques. The model was verified by fitting both simulated and real data. The real data includes several lamp pole point clouds captured by: (1) Faro Focus 3D and (2) Velodyne HDL-32E. The fitting results using the proposed model are promising, and up to 2.9 mm improvement in fitting accuracy was realized for the real lamp pole point clouds compared to using the conventional circular cone model. The overall result suggests that the proposed model is appropriate and rigorous.

Pb-210 behaviour in environmental samples from the Cuban east in 1993

International Nuclear Information System (INIS)

Perez Tamayo, L.; Suarez Pina, W.

1996-01-01

A method based in alpha and beta gross counting, is applied to research behaviour, during 1993, of Pb-210 in atmospheric depositional samples of six sites of the Cuban east. In five of these points, located distant from Cuban centers, the average Pb-210 aport to measured beta activity is predominant (80 +- 20 %) and maximum (> 50 % annual) is observed in coincidence with the first rain full peak. Such regularity may be explained, if assumption is made that principal source of Pb-210 are the continental air masses penetrating the insular atmosphere in winter and that mentioned radionuclide is deposit later with the spring rainfalls. In the sixth point, located at industrial zone, the alpha-beta activities rates are abnormally high, with maximums of 1.5 and 2.4 faced with peak raining and wet months respectively and probably originated by the input atmosphere of rich s in alpha emisors particles from industrial processes

The aim was to evaluate gender differences in depression scores of Iranian and German medical students. Two hundred Iranian medical students (100 men and 100 women) and 200 German medical students (100 men and 100 women) were selected randomly and completed the English form of the self-rating Beck Depression Inventory (BDI). Analysis gave a mean rating of 10.7 ± 6.6 for Iranian men and 10.9 ± 7.81 for Iranian women (NS). Also, 5 ± 4.9 for German men and 5.6 ± 5.0 for German women (NS). On Item 2, which asked whether the person was pessimistic 33% of Iranian men and 30% of Iranian women indicated that they were pessimistic (NS). Also, 21% of German men and 20% of German women indicated that they were pessimistic (NS). On Item 9, which asked about suicidal tendencies, 9% of Iranian men and 13% of Iranian women reported as having suicidal tendencies (NS). Also, 13% of German men and 21% of German women reported as having self-harming thoughts (NS). The present study showed no gender differences in Iranian and German medical students' scores on the BDI.

Dysphoria and somatization in Iranian culture.

Science.gov (United States)

Pliskin, K L

1992-09-01

Iranians express dysphoria through an undifferentiated term called narahati, meaning depressed, ill at ease, nervous, inconvenienced, or anxious. People try masking this emotion or express it in specific ways nonverbally, such as sulking or not eating. Two other dysphoric affects, sadness and anger, are not masked. Because of the social conception of persons being emotionally sensitive, the expression of narahati is guarded: expressing it not only could show that one is socially vulnerable, it could also make another sensitive empathic person narahat. The body is also sensitive, but to the physical world. Physical health is maintained by balancing a diet of "hot" and "cold" foods and avoiding exposure to cold and moisture. With the social and cultural problems brought on by revolution, war, immigration, and accommodation to a new society, Iranian refugees experience changes in family, role, status, finances, language, and other sociocultural ways of being that cause them to feel narahat and to express it verbally, nonverbally, or through somatization. Understanding Iranian conceptions of emotional and physical sensitivity will help clinicians in treating Iranian patients.

2016-12-01

Studying the history of science could help develop an understanding of the contributions made by ancient nations towards scientific advances. Although Iranians had an important impact on the improvement of science, the history of Iranian medicine seems not to have been given enough attention by historians. The present study focused on the history of anesthesia and pain management in Iranian medical history. In this regard, related books such as Avesta and Shahnameh were studied in order to obtain the history of anesthesiology in Iranian pre Islamic era. This subject was also studied in the famous books of Rhazes, Haly Abbas, Avicenna, Jorjani, MomenTunekaboni and Aghili from different times of the Islamic era. Scientific data bases such as PubMed, Scopus and Google Scholar were searched using key words "Iranian", "Persian", "pain management" and "anesthesia". It was discovered that pain management and anesthesiology were well known to the Iranians. Rhazes and Avicenna had innovations in this regard. Fourteen Mokhader (anesthetic) herbs, which were included in the collection of the previous knowledge of the 18th century entitled Makhzan al-Advieyh and used as the Persian Materia Medica, were identified and listed. This study introduces the history of anesthesiology and pain management at different periods in the history of Iran.

Litter presence was assessed on the entire Cuban coastline, and includes 99 beaches from all Cuban regions, during field work carried out in 2012 and 2015. A standard method verified in several countries was applied, which classified beaches for nine types of litter into four grades (A-excellent to D-poor). Almost half of the Cuban beaches obtained excellent cleanliness scores, although many needed to be better managed. In this baseline, the most common types of residue were general litter (8% grade D and 35% grades B/C) and potentially harmful litter (Tourism Impacts seems to be related to visitor origin therefore choices to develop sustainable tourism in rural and village beaches (64%) appears low, if beach cleaning gross investment is focused on resort beaches (24%).

Bagheri, A

1992-02-01

The number of Iranian immigrants in Canada has been increasing since 1979. This study is the result of a review of 111 charts of Iranian patients who were referred for psychiatric treatment between 1985 and 1988. Ninety-eight percent of them arrived in Canada after the Iranian revolution, which started in 1979, and the Iran-Iraq war of 1980. Ten percent were experiencing trauma as a result of their involvement with the revolutionary government or the war. The symptoms were in accordance with the DSM-III-R criteria for post-traumatic stress disorder. Sixty percent met the criteria for adjustment disorder with depressed or anxious mood. Six percent had been subjected to physical and psychological torture and confinement. This is the first study that looks at the prevalence of psychiatric illness among Iranians and illustrates the effect of migration and displacement in the integrity of the psychic life of this population.

2014-01-01

The present study aimed at Investigating the knowledge and attitude of Nursing Students towards Iranian Traditional Medicine in universities of Tehran in 2012-2013. 300 students of nursing studying at different universities in Tehran participated in this descriptive, cross-sectional study. The data was collected through a standard questionnaire with an acceptable validity and reliability. The questionnaire was made of five sections including demographic, general knowledge of the Iranian traditional medicine, general attitude towards it, resources of the Iranian traditional medicine and the barriers to it. The results revealed that general knowledge of the students about Iranian traditional medicine and complementary medicine is low. The attitude of the students towards including Iranian traditional medicine and complementary medicine in their curriculum is positive. General attitude of students towards Iranian traditional medicine is positive too. The majority of the participants had not passed any course on Iranian traditional medicine. There was no relationship between participants’ attitude towards Iranian traditional medicine and the number of semesters they had passed. Considering the participants’ positive attitude and their low level of knowledge, it seems necessary for the university policy makers to provide nursing students with different training courses on Iranian traditional medicine and complementary medicine in order to increase their knowledge.

Cabrera B, E.; Macias B, L.R.

1984-01-01

In the present work it's shown the possibility of obtaining a pole-figure from the data generated in a conventional X-ray equipment, with a commercial goniometer and no electronic device to process the data. The way to plot the pole-figure on-line is by means of measuring the diffractogram and plot manually the stereographic projections. The atainable precision is very low in such a cumbersome process. In this paper we substitute such method by storing the data in a punched tape from a conventional teletype. The data is processed in a computer and the pole-figure is recorded by a plotter attached to the computer. (author)

The present work shows the results obtained in the characterization of gas emissions and the impact of two fire-tube boilers in a Cuban thermal power plant. The results of the SO 2 and NO X sampling were collected in specific solutions for each pollutant. The sampling of suspended particulates in chimneys/pipes/stacks was made by collecting them in a filterholder for their analysis by means of the gravimetric method. Flow measurements were also made by using pressure sensors of Pilot tube-type speedometers. The dispersion modelling of pollutants poured out of the chimneys was developed running the program for the concentration calculation from continuous industrial sources and following the methodology approved by the Cuban standard according to Berliand model. The authors conclude that when burning national crude oil in the studied boilers, sulphur dioxide concentrations and suspended particulates are higher than the internationally standardized level

Pole shifting with constrained output feedback

International Nuclear Information System (INIS)

Hamel, D.; Mensah, S.; Boisvert, J.

1984-03-01

The concept of pole placement plays an important role in linear, multi-variable, control theory. It has received much attention since its introduction, and several pole shifting algorithms are now available. This work presents a new method which allows practical and engineering constraints such as gain limitation and controller structure to be introduced right into the pole shifting design strategy. This is achieved by formulating the pole placement problem as a constrained optimization problem. Explicit constraints (controller structure and gain limits) are defined to identify an admissible region for the feedback gain matrix. The desired pole configuration is translated into an appropriate cost function which must be closed-loop minimized. The resulting constrained optimization problem can thus be solved with optimization algorithms. The method has been implemented as an algorithmic interactive module in a computer-aided control system design package, MVPACK. The application of the method is illustrated to design controllers for an aircraft and an evaporator. The results illustrate the importance of controller structure on overall performance of a control system

Scientific journals are the most credible and updated information resources for valid information in the various fields of science and technology. The present study investigates the status of Iranian scientific journals in disseminating medical information to the world of science. Total 163 Iranian medical journals accredited by national medical journals commission of Iranian ministry of health and medical education were evaluated through a cross-sectional study. The results were represented in descriptive statistics in the form of table and chart. The study showed that 89.6% of Iranian medical journals were covered by regional information databases. Web of Science database indexed 22 (13.5%) Iranian journals in the field of medical science. Only six (6.7%) journals were indexed by Medline. Fifty-eight (35.6%) journals were in English, 102 (62.6%) in Persian, and three (1.8%) were bilingual which published their articles both in Persian and English languages. The highest Impact factor belonged to Iranian Journal of Allergy Asthma and Immunology. Improving scientific credibility of Iranian scholarly journals and their influence in disseminating medical information calls for a precise scientific and executive administration in publishing standards and also in the quality of content.

Utility poles not affected by CCA decision

Energy Technology Data Exchange (ETDEWEB)

De Venzio, H. [Arch Wood Protection Canada, Mississauga, ON (Canada)

2002-08-01

A voluntary decision by industry to move non-industrial use of treated lumber products away from pressure-treated wood containing chromated copper arsenate (CCA) preservative was announced by the Environmental Protection Agency on February 12, 2002. Although new alternative wood preservatives would be used, this decision does not affect utility poles, which will continue to be sold and installed. The author provides a brief historical outline concerning the creation of CCA in 1933 and its subsequent uses. CCA has many advantages, including clean surface of the poles, ground line treatment that is not required thus eliminating the requirement to rotate the poles during extended storage periods. Conductivity is low, as is corrosivity without affecting the bending characteristics of the wood. The injection of a refined hydrocarbon oil emulsion in the outer layer of the pole after the treatment with CCA is offered by some pole producers to facilitate gaff penetration. Sawing, drilling and nailing are also made easier. Water repellents can be added to the treating solution to improve climbability, slowing down the absorption and release of moisture. Warranties, extending for 50-year periods, are offered by some companies against wood-destroying organisms. The North American Wood Pole Coalition (NAWPC) was formed in 1998 to promote the use of wood poles, and publishes brochures and technical bulletins to that effect.

The Cuban power sector faces a need for extensive investment in new generating capacity, under a large number of uncertainties regarding future conditions, including: rate of demand growth, fluctuations in fuel prices, access to imported fuel, and access to investment capital for construction of new power plants and development of fuel import infrastructure. To identify cost effective investment strategies under these uncertainties, a supply and power sector MARKAL model was assembled, following an extensive review of available data on the Cuban power system and resource potentials. Two scenarios were assessed, a business-as-usual (BAU) scenario assuming continued moderate electricity load growth and domestic fuel production growth, and a high growth (HI) scenario assuming rapid electricity demand growth, rapid increase in domestic fuel production, and a transition to market pricing of electricity. Within these two scenarios sets, sensitivity analyses were conducted on a number of variables. The implications of least-cost investment strategies for new capacity builds, investment spending requirements, electricity prices, fuel expenditures, and carbon dioxide emissions for each scenario were assessed. Natural gas was found to be the cost effective fuel for new generation across both scenarios and most sensitivity cases, suggesting that access to natural gas, through increased domestic production and LNG import, is a clear priority for further analysis in the Cuban context.

Knowing the Place for the First Time: A Cuban Exile’s Story

Full Text Available Playa Abierta is a modern beach-side resort, one hundred kilometres west of Havana. Developed as a private resort in the 1950s, it was seized by the new revolutionary Cuban government in 1959 after its owner fled precipitately to Miami. This autobiographically centred and personally narrated paper reviews the history of Playa Abierta 1956 – 2006 through the eyes of a Cuban New Zealander ‘Marta’ whose uncle first developed the estate. In 1956 her holidays spent at Playa Abierta as a little girl were her most treasured Cuban moments. ‘At this altar’, she says, ‘my uncle was the high priest.’ In 1996 - after a 36-year absence from her native land - she returned for a visit, the only member of her extended family to have done so. Boldly and unannounced she walked through her uncle’s house – by then converted into a military recreational camp. On a subsequent visit, she met with members of her uncle’s domestic staff whose relationship to that same loved beach was by then of many decades. Whose Playa Abierta was she re-visiting now? Who were the true claimants to that family sacred site? Today as she reflects on the private and public meaning of Playa Abierta, her exultation has given way to more complex feelings. The wonder at re-discovering the beach’s beauty was overladen with the guilt of returning to Cuba while still under Castro’s communist rule. Her sense of belonging was later undermined by a sad realisation that those who had stayed behind were also Playa Abierta’s claimants. Above all, she is torn between family loyalties and the promise of a Revolution betrayed.

The coil stack assembly is important for reliable operation of the CEDM, there have been efforts to improve the design by optimizing the design parameters such as dimensions and winding turns. However, magnetic forces of the CEDM can also change by different pole arrangement even if their design parameters are the same. Since the latch coil and lift coil are installed connected to each other, they produce magnetically coupled field when they are energized at the same time. This coupling field can affect the magnetic force of the CEDM significantly. In this paper, coil pole arrangement effects are studied. Electro-magnetic analysis is performed for the different pole arrangements of the CEDM coils to calculate the magnetic forces. Pole arrangement effects on magnetic forces were studied by static analysis of the CEDM magnetic field. Magnetic forces were calculated and compared for the two different pole arrangements of the coils. The results show that the magnetic poles of the lift coil and latch coil shall be arranged to have the same magnetic pole direction to achieve higher magnetic force

Nutritional Care in Iranian Intensive Care Units

Intensive care units (ICUs) provides intensive treatment medicine to avoid complications such as malnutrition, infection and even death. As very little is currently known about the nutritional practices in Iranian ICUs, this study attempted to assess the various aspects of current nutrition support practices in Iranian ICUs. We conducted a cross-sectional study on 150 critically ill patients at 18 ICUs in 12 hospitals located in 2 provinces of Iran from February 2015 to March 2016. Data were collected through interview with supervisors of ICUs, medical record reviews and direct observation of patients during feeding. Our study showed that hospital-prepared enteral tube feeding formulas are the main formulas used in Iranian hospitals. None of the dietitians worked exclusively an ICU and only 30% of patients received diet counselling. Regular monitoring of nutritional status, daily energy and protein intake were not recorded in any of the participating ICUs. Patients were not monitored for anthropometric measurements such as mid-arm circumference (MAC) and electrolyte status. The nasogastric tube was not switched to percutaneous endoscopic gastrostomy or jejunostomy (PEG/PEGJ) in approximately 85% of patients receiving long-term enteral nutrition (EN) support. Our findings demonstrated that the quality of nutritional care was inappropriate in Iranian ICUs and improvement of nutritional care services within Iranian ICUs is necessary. PMID:29713622

Rotor pole refurbishment for hydrogenerators: insulation problems and solutions

Reynolds, R.R.; Rux, L.

2005-01-01

Rotor poles for Unit 1 at Lower Granite Powerhouse were removed from the rotor and shipped to a repair facility for refurbishment. Upon inspection, it was found that all of the pole bodies exhibited a distinct bow, center to end, on the pole mounting surface. In some cases, the deflection was as much as 0.106 inch. Concerns were raised about how this condition might affect the ability to properly insulate and/or re-seat the poles. This paper presents details of the rotor pole and field winding evaluation, the problems encountered, and the solutions implemented to successfully refurbish the rotor poles and field winding.

Full Text Available In this research paper, the author addresses the following four questions: 1 What are the implications of bringing pole dancing into concert dance, not as a caricature or theatrical version of what is performed in strip clubs, but as its own, free-standing art form? 2 In what ways will years of ballet and modern dance training influence the type of dancing that emerges from dancers when poles and other apparatuses are introduced? 3 How can the author create an original pole dancing style and pedagogical methods for teaching it? 4 Who participates in pole fitness classes and how does the demographic change based on location? What about when pole fitness classes are offered in an academic setting? The author shares first-hand experiences of investigating pole dancing in fitness classes, attending performances, engaging in a rehearsal process with highly trained dancers, and teaching pole dancing to movers with a wide range of abilities. The author addresses how research plans changed as she encountered limitations of budget and time constraints. The author also elaborates on the creative process that she engaged in with her thesis cast, collaborators, and supporting designers in the making of Super-beneath, a theatrical dance work that uses five, free-standing poles. She outline the vignettes, overall structure, and narrative of the work. The author then discusses where this research fits into the larger field of pole dancing, and the even larger field of dance. In the final sections of this paper, the author describes her pedagogical practices relating to pole classes, what “practice as research” means to her, and how she would like to continue on this research trajectory in the future.

Full Text Available Strained relations between the US and Cuba after the victory of the Cuban revolution were a permanent element of the destabilization of international security in the Western Hemisphere. During the Cold War, this destabilization was a function of the East-West confrontation. Since the end of Cold War the importance of Cuba as a Western Hemisphere entity hostile to the United States has diminished radically. Definite steps to normalize relations with Cuba have been taken only in 2014. The media named the change of policies of the US towards Cuba (and Iran as the Obama Doctrine. This article will try to prove that the continuation of the confron-tational and hostile US-Cuban relations after the collapse of the Eastern bloc was an exceptional and "unnatural" phenomenon from the perspective of realistic school of international relations, both for Washington and Havana.

Soil hydraulic properties of Cuban soils

International Nuclear Information System (INIS)

Ruiz, M.E.; Medina, H.

2004-01-01

Because soil hydraulic properties are indispensable for determining soil water retention and soil water movement, their input for deterministic crop simulation models is essential. From these models is possible to access the effect of the weather changes, soil type or different irrigation schedules on crop yields. With these models, possibilities are provided to answer questions regarding virtual 'what happen if' experiments with a minimum of fieldwork. Nevertheless, determining soil hydraulic properties can be very difficult owing to unavailability of necessary equipment or the lack of personal with the proper knowledge for those tasks. These deficiencies are a real problem in developing countries, and even more so when there is not enough financial possibilities for research work. This paper briefly presents the way these properties have been accessed for Cuban soils, which methods have been used and the work now in progress. (author)

Solar Open Flux Migration from Pole to Pole: Magnetic Field Reversal.

Science.gov (United States)

Huang, G-H; Lin, C-H; Lee, L C

2017-08-25

Coronal holes are solar regions with low soft X-ray or low extreme ultraviolet intensities. The magnetic fields from coronal holes extend far away from the Sun, and thus they are identified as regions with open magnetic field lines. Coronal holes are concentrated in the polar regions during the sunspot minimum phase, and spread to lower latitude during the rising phase of solar activity. In this work, we identify coronal holes with outward and inward open magnetic fluxes being in the opposite poles during solar quiet period. We find that during the sunspot rising phase, the outward and inward open fluxes perform pole-to-pole trans-equatorial migrations in opposite directions. The migration of the open fluxes consists of three parts: open flux areas migrating across the equator, new open flux areas generated in the low latitude and migrating poleward, and new open flux areas locally generated in the polar region. All three components contribute to the reversal of magnetic polarity. The percentage of contribution from each component is different for different solar cycle. Our results also show that the sunspot number is positively correlated with the lower-latitude open magnetic flux area, but negatively correlated with the total open flux area.

New safety performance indicators for safety assessment of radioactive waste disposal facilities. Cuban experience

International Nuclear Information System (INIS)

Peralta Vital, J.L.; Castillo, R.G.; Olivera, J.

2002-01-01

The paper shows the Cuban experience on implementing geological disposal of radioactive waste and the necessity for identifying new safety performance indicators for the safety assessment (SA) of radioactive waste disposal facilities. The selected indicator was the concentration of natural radioactive elements (U, Ra, Th, K) in the Cuban geologic environment. We have carried out a group of investigations, which have allowed characterising the concentration for the whole Country, creating a wide database where this indicator is associated with the lithology. The main lithologies in Cuba are: the sedimentary rocks (70 percent of national occurrence), which are present in the three regions (limestone and lutite), and finally the igneous and metamorphic rocks. The results show the concentrations ranges of the natural radionuclides associated fundamentally to the variation in the lithology and geographical area of the Country. In Cuba, the higher concentration (ppm) of Uranium and Radium are referenced to the Central region associated to Skarn, while for Thorium (ppm) and Potassium (%), in the East region the concentration peaks in Tuffs have been found. The concentrations ranges obtained are preliminary, they characterise the behaviour of this parameter for the Cuban geology, but they do not represent limits for safety assessment purposes yet. Also other factors should be taken into account as the assessment context, time scales and others assumptions before establishing the final concentration limits for the natural radionuclides as a radiological and nuclear safety performance indicator complementary to dose and risk for safety assessment for radiological and nuclear facilities.

Cross-poling textures in a lead zirconate titanate piezoelectric material

International Nuclear Information System (INIS)

Wan, Shan; Bowman, Keith J.

2000-01-01

Tetragonal ferroelectric materials are polarized to induce the anisotropy necessary for the piezoelectric effect. This poling of the material is inherently an orientation process. Pole figure texture measurements of poling and cross-poling in a lead zirconate titanate Navy VI material show domain motion. The resulting axisymmetric and three-dimensional textures demonstrate the contribution of 90 degree sign domain motion to piezoelectricity. Cross-poling results in strong orientations with lower applied fields than in the initial poling steps. (c) 2000 Materials Research Society

Reuse of poles treated with CCA; CCA-kyllaestettyjen puupylvaeiden uudelleenkaeyttoe

This study investigated the feasibility of re-using utility poles or parts of poles for structural use in construction. There are more than 10 million poles in Finland and about 200 000 poles will be removed from service yearly during the next few years. The directive 2003/2/EY will restrict the use of poles treated with CCA. This will change the practice that the energy and telecommunication companies have given the removed poles to the land owners. The present study launched by the Technical Research Centre of Finland (VTT) was carried out to determine the technical condition of CCA impregnated poles removed from service and the concentration levels and leaching of remaining preservatives. To summarize the results of the tests, it is safe to say that re-use of recovered poles of 30 to 50 years of age is possible. Both the preservative concentrations and strength/load-bearing capacity are high enough to allow the use of the poles as load-bearing structures. (orig.)

The pole tide in deep oceans

Science.gov (United States)

Dickman, S. R.

1990-01-01

The fluid-dynamical theory of the pole tide is examined by describing the oceanic response to the Chandler wobble and assessing its implications for mantle anelasticity and low-frequency ocean dynamics. The Laplace tide equations accounting for bottom friction are given, and a spherical harmonic approach is delineated in which the time-independent portion of the tide height is expanded. Pole-tide height and related inertia products are linearly proportional to wobble amplitude, and the final equations are modified to account for mantle elasticity and oceanic loading. Results for pole tide effects are given for various earth models with attention to the role of boundary constraints. A dynamic effect is identified which lengthens the Chandler period by about 1 day more than static lengthening, a contribution that suggests a vigorous low-frequency response. The values derived are shown to agree with previous models that do not incorporate the effects of the pole tide.

Germline mutations in the exonuclease domain of POLE have been shown to predispose to colorectal cancers and adenomas. POLE is an enzyme involved in DNA repair and chromosomal DNA replication. In order to assess whether such mutations might also predispose to cutaneous melanoma, we interrogated...... variants in the exonuclease domain of POLE. Although this frequency is not significantly higher than that in unselected Caucasian controls, we observed multiple cancer types in the melanoma families, suggesting that some germline POLE mutations may predispose to a broad spectrum of cancers, including...

Plotter of pole figure using data from x-ray diffraction

1990-01-01

Any polycrystalline aggregate normally has a preferred crystallographic orientation, or texture which depends on its thermal and or mechanical history. Preferred orientation is best described by means of a pole figure. A pole figure is a stereographic projection which shows the variation in pole density with pole orientation, for a selected set of crystal planes. In this work, computer programs was developed to plot pole figures. The corrected intensities are calculated and directly transmitted to the plotter. The different intensities levels are represented by different colors in the pole figure. (author)

Effects of slotting and unipolar flux on magnetic pull in a two-pole induction motor with an extra four-pole stator winding

Energy Technology Data Exchange (ETDEWEB)

Sinervo, A.

2013-06-01

This thesis is about the radial magnetic forces between the rotor and stator in twopole induction machines. The magnetic forces arise from rotor eccentricity. The asymmetric air-gap makes the flux density on one side of the rotor stronger than on the opposite side. This produces magnetic pull. The magnetic flux density distribution in the air-gap can be expressed with spatial harmonics, i.e. flux densities with different pole-pair numbers. In two-pole machines, the main part of the magnetic force is produced by the interaction of two- and fourpole flux unless the four-pole flux is damped by parallel paths in the stator winding or an extra four-pole stator winding. The rest of the force comes from the interaction of two-pole and unipolar flux and from the higher harmonics of the air-gap flux of which the slot harmonics are a major part. The force caused by the higher harmonics and the unipolar flux is studied in the case where a four-pole stator winding is used to reduce the four-pole flux. The higher harmonics are found to produce, in addition to the traditional unbalanced magnetic pull, a force similar to the effect of the unipolar flux and the two can be distinguished only by measuring the unipolar flux. In measurements at various operation points, the higher harmonics are found to produce much more force than the unipolar flux and two-pole flux but the unipolar flux is still significant. The four-pole winding also is used to actively control the four-pole flux and the magnetic forces. Designing the controller requires a low order model of the system. Such a model is derived and the effect of the slot harmonics and the unipolar flux are included in the model. Different measurements techniques and methods are presented to identify and validate the control model. The operation point dependence of the system dynamics is studied via measurements. All results are obtained from a 30 kW test motor. The rotor of the test machine has a long flexible shaft on external

Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Three known textbooks (Ingle's Endodontics, Seltzer and Bender's Dental Pulp and Cohen's Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen's Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000.

Repair and rehabilitation of wood utility poles with fibre-reinforced polymers

Polyzois, D.; Kell, J.A. [Manitoba Univ., Winnipeg, MB (Canada). Dept. of Civil Engineering

2007-01-15

In order to ensure safe and reliable service, all wood utility poles need an effective maintenance program. The service life of a wood utility pole depends on several factors, such as decay, mechanical damage, weathering, and changing design requirements. An effective preservative treatment and maintenance program can effectively extend the service life of the wood pole. However, all poles will attain a point when they are no longer suitable for their intended use. New innovative methods are therefore required to restore and maintain the structural integrity of existing wood poles, especially in light of the increasing cost of quality wood for use in poles as well as a result of environmental concerns regarding pole disposal and chemical treatment of existing poles. This article presented results from a research program carried out at the University of Manitoba to develop a repair and rehabilitation technique for wood poles using fibre-reinforced polymers (FRP). It also provided a brief overview of current standards for wood utility poles and reinforcing stubs and discussed the experimental program where long, air-dried jack pine poles were tested in order to evaluate the effectiveness of a proposed rehabilitation system consisting of FRP splines and FRP jackets. The ultimate capacity of the poles was determined using the CSA standard for wood poles. The capacity of the rehabilitated poles was nearly 93 per cent of the average ultimate capacity of the average ultimate capacity of poles tested during the first phase of the study, and 23 per cent higher than the capacity required by CSA standards. 7 refs., 2 figs., 4 tabs.

Design of a portable CAT scanner for utility pole inspection

Miller, W.H.

1986-01-01

Work is under way at the University of Missouri, Columbia (UMC) to design, build, and test a portable computerized axial tomography (CAT) device for the nondestructive, field imaging of wooden utility poles. CAT is a well-established medical technology that has recently been applied to a number of industrial applications. Wooden utility poles are prone to rot and decay at ground level; current techniques to assess this loss of strength are relatively primitive, i.e., tapping the pole (hitting the pole with a hammer) or boring into the pole for samples and then testing inside the bore hole with an electrical pulse device. The accuracy in identifying poles needing replacement using these techniques is ∼ 70%. Since the cost of replacing a pole ranges from hundreds to thousands of dollars, an accurate, nondestructive method is needed. CAT can accurately image a wooden utility pole (since the size, density, and atomic elements of a pole are similar to the human head to torso), as was confirmed by imaging poles using the UMC nuclear engineering EMI-1010 medical scanner. Detailed images have been produced showing the ring structure of the wood and voids due to rot or decay. Images approaching this quality have also been produced on living trees using semiportable systems by other researchers

In Situ Poling and Imidization of Amorphous Piezoelectric Polyimides

Park, Cheol; Ounaies, Zoubeida; Wise, Kristopher E.; Harrison, Joycelyn S.; Bushnell, Dennis M. (Technical Monitor)

2002-01-01

An amorphous piezoelectric polyimide containing polar functional groups has been developed using a combination of experimental and molecular modeling for potential use in high temperature applications. This amorphous polyimide, (Beta-CN)APB/ODPA, has exhibited good thermal stability and piezoelectric response at temperatures up to 150C. Density functional calculations predicted that a partially cured amic acid (open imide ring) possesses a dipole moment four times larger than the fully imidized closed ring. In situ poling and imidization of the partially cured (Beta-CN)APB/ODPA, was studied in an attempt to maximize the degree of dipolar orientation and the resultant piezoelectric response. A positive corona poling was used to minimize localized arcing during poling and to allow use of higher poling fields without dielectric breakdown. The dielectric relaxation strength, remanent polarization, and piezoelectric response were evaluated as a function of the poling profile. The partially cured, corona poled polymers exhibited higher dielectric relaxation strength (delta varepsilon), remanent polarization (Pr) and piezoelectric strain coefficient (d33) than the fully cured, conventionally poled ones.

Endemics under threat: an assessment of the conservation status of Cuban bats

Directory of Open Access Journals (Sweden)

Carlos Mancina

2007-07-01

Full Text Available Abstract Reviewing available information from published literature, museum database, personal communications and from the authors own field data, the conservation status of Cuban bats has been assessed using six qualitative parameters: abundance, distribution, roosting habits, aggregation level, forest dependence, and degree of endemism. The resulting Red List is analogous to that of the IUCN, species having been included in four categories of risk. Four out of the 26 extant bats of Cuba should be considered endangered, four vulnerable to extinction, twelve potentially threatened, and six in a stable situation. Most of the species of bats endemic to Cuba are under some form of threat. The major threats to the survival of Cuban bats are the destruction of forests and the modification of caves, the latter being critical habitats for the mostly cave-dwelling Cuban bat fauna. We argue that its conservation should be the result of a cooperative effort promoting research and habitat management. Riassunto Endemismi minacciati: una valutazione dello stato di conservazione dei chirotteri cubani. Lo stato di conservazione dei chirotteri cubani è stato valutato a partire da sei parametri qualitativi: abbondanza, distribuzione, roost utilizzati, livello di aggregazione, dipendenza da ambienti forestali e grado di endemismo. A questo scopo sono state esaminate le informazioni bibliografiche, i database dei musei e dati non pubblicati, in parte raccolti dagli stessi autori. La Lista Rossa risultante è analoga a quella dell’IUCN, comprendendo quattro categorie di rischio crescente. Delle 26 specie attualmente presenti a Cuba, 4 sono da considerarsi in pericolo di estinzione, 4 "vulnerabili", 12 "potenzialmente minacciate" e 6 "stabili". La maggior parte delle specie endemiche è in qualche misura minacciata. La deforestazione e l’alterazione delle cavità carsiche, che costituiscono un habitat

A poling study on lead zirconate titanate composition

International Nuclear Information System (INIS)

Bryant, P.J.

1992-01-01

Ceramics produced by the conventional mixed oxide route are dual phased. Because the titania and zirconia are not perfectly homogenized, some parts of the ceramic are more tetragonal (titanium rich) and other parts more rhombohedral (zirconium rich). This inhomogeneity means that some domains can be more easily poled than others. Lastly, the density and porosity can affect the poling process if the flaw density becomes such that the breakdown voltage is exceeded by the required poling voltage. The phase boundary determined by most dielectric and piezoelectric measurements is significantly removed from the 44% titanium content determined by neutron diffraction. The indicators that are most consistent with this value are the minimum in the poling efficiency curve and the shape of the dissipative factor curve. The reason for the discrepancy appears to be related to the broad coexistence region of the two phases and the differing poling efficiencies of each phase. It has been established that different poling temperature profiles can substantially modify the observed properties. Such behaviour is again related to the inhomogeneity of the ceramic and the presence of the two phases. 4 refs., 5 figs

Full Text Available In this article, we studied student dissertations in cultural studies departments and articles of two important journals (Iranian Journal of Cultural Research and Quarterly Journal of Iranian Association for Cultural Studies & Communication. Our main questions are how the condition of reception possibility is assumed in Iranian cultural studies? How we can classify our audiences? In particular, how and who is the audience in Iran? This analysis shows that most of the Iranian cultural studies oriented to urban middle class of Tehran, instead of lower middle class or labor class. The result demonstrates that, most of scholars consider audience as an active subject that resists against text massages. Hence, they overlook the role of ideology and power in construction of subject and audience. As if, a type of optimistic cultural studies was adapted in an authoritarian political context. This approach on resistance is called resistance ideology by the authors; a situation in which we believe resistance is a sort of relieving and appeasing drug for critical cultural scholars.

Bismuth ferrite (BiFeO3) is difficult to pole because of the combination of its high coercive field and high electrical conductivity. This problem is particularly pronounced in thick films. The poling, however, must be performed to achieve a large macroscopic piezoelectric response. This study presents evidence of a prominent and reproducible self-poling effect in few-tens-of-micrometer-thick BiFeO3 films. Direct and converse piezoelectric measurements confirmed that the as-sintered BiFeO3 thick films yield d33 values of up to ∼20 pC/N. It was observed that a significant self-poling effect only appears in cases when the films are heated and cooled through the ferroelectric-paraelectric phase transition (Curie temperature TC ∼ 820 °C). These self-poled films exhibit a microstructure with randomly oriented columnar grains. The presence of a compressive strain gradient across the film thickness cooled from above the TC was experimentally confirmed and is suggested to be responsible for the self-poling effect. Finally, the macroscopic d33 response of the self-poled BiFeO3 film was characterized as a function of the driving-field frequency and amplitude.

Several polymer molecules have structures which are suitable for the non-linear optic applications. We report on the design and fabrication of a high performance electro-optic modulator made of polymer thin films. The polymer we study contains a chromophore based on Disperse Red One covalently grafted to a host-matrix. The polymer materials are deposited in thin layers on a glass substrate by chemical solution deposition, either by spin-coating or by dip-coating. The thickness of the films is ranging from a hundred nanometers to several micrometers. Initially, the polymer molecules are randomly oriented and the films are isotropic, hence no electro-optic effect can be observed. In order to break the symmetry and align the chromophores, the films are submitted to the so-called corona poling process. As a result, their structure become non-centrosymmetric and the second-order susceptibility is no longer zero. The corona poling method consists of applying a high electric field to the polymer by means of a needle electrode, placed above the polymer film which is posed on a grounded sample support electrode. Thermal regulation of the support electrode allows to control the temperature during the poling of the films. Once the poling process has been established, a chemical cross-linking function is thermally activated in order to fix the orientation of the chromophores in the polymer matrix. The orientation and its stability in time is evaluated with a Second Harmonic Generation measurement set-up using the Makers Fringes configuration. We studied the influence of the poling temperature, the distance between the corona needle electrode and the sample, the high voltage applied, and the duration of the poling process on the efficiency of chromophore orientation in order to optimize the poling procedure. Finally, aging of poled polymer samples has been investigated at elevated temperatures, confirming the stability of the cross-linking process.

Introduction: Shock wave lithotripsy (SWL) is a treatment option for all locations of renal and ureteric stones. We compared the results of SWL for lower pole renal stones with all other non-lower pole renal and ureteric stones during the same time period. Material and Methods: All SWL procedures were carried out as day case procedures by a mobile lithotripter from January 2012 to August 2013. The follow-up imaging was a combination of KUB X-ray or USS. Following SWL treatment, the stone free rate (SFR) was defined as ≤3 mm fragments. Results: A total of 148 patients with a mean age of 62 years underwent 201 procedures. Of the 201 procedures, 93 (46%) were for lower pole stones. The non-lower pole stones included upper pole (n = 36), mid pole (n = 40), renal pelvis (n = 10), PUJ (n = 8), mid ureter (n = 3), upper ureter (n = 5) and a combination of upper, middle and/or lower pole (n = 6). The mean stone size for lower pole stones (7.4 mm; range: 4-16 mm) was slightly smaller than non-lower pole stones (8 mm; range: 4-17 mm). The stone fragmentation was successful in 124 (62%) of patients. However, the SFR was statistically significantly better (P = 0.023) for non-lower pole stones 43 (40%) compared to lower pole stones 23 (25%). There were 9 (4%) minor complications and this was not significantly different in the two groups. Conclusions: Although SWL achieves a moderately high stone fragmentation rate with a low complication rate, the SFR is variable depending on the location of stone and the definition of SFR, with lower pole stones fairing significantly worse than stones in all other locations.

Oysters (Crassostrea virginica) collected on the Cuban coast near Havana were examined for contamination with Vibrio cholerae and other potentially pathogenic Vibrio species. The strains thus isolated were characterized and identified to species following standard methods, and their radiation resistance (D{sub 10}) was determined in pure culture. The Vibrio species most often isolated were V. cholerae, V. parahaemolyticus and V. Alginolyticus. Representative cultures from each species were later used to inoculate shucked oysters to determine the optimal radiation dose that would ensure elimination of 10{sup 8} colony forming units (CFU)/g. The highest proportion of isolates were identified as Vibrio parahaemolyticus and V. algynoliticus. Non-O1 strains of Vibrio cholerae were isolated from 50% of samples, but no V. cholerae O1 was identified. D{sub 10} values calculated for the various strains were low in relation to those in the literature. The radiation dose for decontaminating heavily inoculated (10{sup 8} CFU/g) oysters was 1.2 kGy.

Pressure transmitter surveillance: the dominant real pole case

International Nuclear Information System (INIS)

Blazquez, J.; Ballestrin, J.

1995-01-01

There are about 500 pressure transmitters in a nuclear power plant. Due to Safety requirements, some of them must be specially surveilled. Sensor response time to a pressure ramp is the usual quantity to be measured. Response time, τ r , reflects the dynamics of the sensor and the sensing line. A real pole is due to the inner sensor structure, but the complex pole stands for the sensing line too. The real pole usually is the dominant in most sensors. On line monitoring noise analysis regards simultaneously both, the sensor and the sensing line, but the noise signal contains not only the sensor poles, but many others coming from the plant, so must be conditioned previously and the determination of τ r is not free of systematic errors. That is the price to be paid for non disturbing the plant. When the real pole is dominant, the sensing line contribution is negligible, so the on line noise monitoring methods are supported by the laboratory experiments and the real pole border in the PSD is properly identified. The mean square frequency results proportional to τ r -1 , so manual techniques are designed for response time surveillance made by non noise plant's maintenance technicians. (author)

The Iranian Nuclear in Perspective

International Nuclear Information System (INIS)

Richard, Yann

2008-01-01

The civil nuclear constitutes an alibi for Iran which the real aim is the access to the military nuclear power. It was probably the initial goal, before and after the 1979 revolution. The provocative speech of Iranian rulers on Israel constitute a reason to enrich uranium at military ends. But it appears that's not the only reason for Iran to pursue its nuclear program. Will not be efficient to begin sincere negotiations with Iran and to engage a policy of denuclearization of the region? Moreover the international interferences on the Iranian matters could be detrimental. Indeed, democratic freedoms won't spread in Iran, if the great decisions that concern the country don't take into account the national willing

Images of Jupiter's poles show a chaotic scene, unlike Saturn's poles. Microwave sounding reveals weather features at pressures deeper than 100 bars,...... of magnitude more precise. This has implications for the distribution of heavy elements in the interior, including the existence and mass of Jupiter's core. The observed magnetic field exhibits smaller spatial variations than expected, indicative of a rich harmonic content....

Particles as S-matrix poles: hadron democracy

International Nuclear Information System (INIS)

Chew, G.F.

1989-01-01

The connection between two theoretical ideas of the 1950s is traced in this article, namely that hadrons are nonfundamental, ''composite'' particles and that all physically observable particles correspond to singularities of an analytic scattering matrix. The S matrix theory developed by Werner Heisenberg in the early forties now incorporated the concepts of unitarity, invariance, analyticity and causality. The meson-exchange force meant that poles must be present in nucleon-nuclear and pion-nucleon scattering as predicted by dispersion relations. Experimental work in accessible regions determined pole residues. Pole residue became associated with force strength and pole position with particle mass. In 1959, the author discovered the so-called ''bootstrap'' theory the rho meson as a force generates a rho particle. By the end of the 1950s it was clear that all hadrons had equal status, each being bound states of other hadrons, sustained by hadron exchange forces and that hadrons are self-generated by an S-matrix bootstrap mechanism that determines all their properties.

With the coming shortage of fossil fuels it is important to develop energy efficient buildings to reduce both energy consumption and pollution at the same time. In Iran, traditional homes have been built in a sustainable manner to withstand the high climate diversity of the country. The aim of this paper is to present the different methods used in Iranian traditional architecture. Among the architectural principles is appropriate orientation of the building to allow the capture of solar energy and at the same time protect against the cold wind. In addition, indigenous materials were used in the constructions to provide the highest degree of comfort possible with minimal damage to the environment. Finally, Iranian traditional architecture took advantage of the soil's constant temperature by building a Shvadan which is an underground space beneath the house. This article highlighted the different Iranian traditional methods which can create a sustainable architecture.

Context: Insomnia is one of the most prevalent sleep disorders characterized by sleep difficulty that impairs daily functioning and reduces quality of life. The burden of medical, psychiatric, interpersonal, and societal consequences of insomnia expresses the importance of diagnosing and treatment of insomnia. The aim of study was to investigate causes of insomnia from the viewpoint of Iranian traditional medicine. Evidence Acquisition: In this review study, we searched insomnia in a few of the most famous ancient textbooks of Iranian traditional medicine from different centuries. This books includeThe Canon of Medicine by Avicenna (the first version of Beirut), Zakhire Kharazmshahi by Jurjani (the scanned version of Bonyade Farhang-e Iran), Malfaregh by Razes (the first version of Iran University of Medical Sciences), and Aqili’s cure by Aqili (the first version of Iran University of Medical Sciences). Results: This study found that in Iranian traditional medicine manuscripts, insomnia was called sahar and even though many factors induce insomnia, most of them act through causing brain dystemperament. Conclusions: The brain dystemperament is considered one of the main causes of insomnia and insomnia can be well managed with an organized line of treatment, by correcting the brain dystemperament through elimination of causes. This study helps to find new solutions to treat insomnia. PMID:24829786

The ability of a mixed marine bacteria culture to degrade Pina Cuban crude oil in the presence of nutrients and sea water was studied. Laboratory experiments were conducted in flasks with 100 ml of saline liquid containing 1 per cent crude. The flasks were inoculated with marine bacteria (IDO-225, IDO-226, and IDO-229) at a final concentration of 10{sup 6} cell/ml. The cultures were grown at 29 degrees C for 21 days. Bacterial growth, and surface and interfacial tension were measured after 5, 13 and 21 days. Results showed that the marine bacteria were effective in accelerating the biodegradation process of Pina Cuban oil. The efficiency of the process increased when nutrients were added to the system. This biopreparation also accelerated emulsification of the oil without any negative effects to the natural microbiota. The biological oxygen demand at five days and at the end of the experiment was determined. The biodegradation constant and the biochemical stabilization constant were also measured. 14 refs., 5 tabs., 4 figs.

Angiostrongylus cantonensis meningitis was first reported in Cuba in 1981, and it was recently reported in South America. The aim of this paper is to evaluate the intrathecal immunoglobulin synthesis patterns from Cuba's and Ecuador's patients with angiostrongyliasis; 8 Ecuadorian patients from two different outbreaks and 28 Cuban patients were studied. Simultaneous blood and cerebrospinal fluid simples were taken. Immunoglobulin (Ig) A, IgM, IgG, and albumin were quantified by radial immunodiffusion. Corresponding Reibergrams were applied. A three-Ig pattern was the most frequent in the two groups, but IgM was presented in all Ecuadorian young mature patients; however, in the Cuban children, only 12 of 28 patients had intrathecal IgM, but about 90% had an IgA and IgG synthesis at time of later puncture. This indicates that, with a larger amount of parasites ingested, clinical symptoms are more severe, and a higher frequency of intrathecal IgM synthesis could be observed. This is discussed as a similarity with the intrathecal IgM synthesis in African trypanosomiasis. PMID:21363978

Organizational Citizenship Behavior (OCB) is defined as "individual behavior that is discretionary, not directly or explicitly recognized by the formal reward system, and that in the aggregate, promotes the effective functioning of organization". OCB, enhance job satisfaction among nursing employees. According to several findings, nurses' OCB have a positive and significant influence on job satisfaction. This research is aimed to study OCB among Iranian nurses. A cross-sectional, descriptive and analytical study was conducted among 510 nurses working in 15 teaching hospitals in Tehran, Iran to be selected by stratified random sampling. The respondents were asked to complete Netemeyer's organizational citizenship behavior questionnaire that encompassed four dimensions of OCB including Sportsmanship, Civil Virtue, Conscientiousness, Altruism and selected each item of OCB dimensions and identified their attitudes about OCB items were observed in hospitals of Tehran. The data was analyzed by T-test, ANOVA and Pearson statistical methods. The results of this research showed that most of the nurses who studied in this study, had OCB behaviors. Also, we found that there was significant correlation between Iranian nurses' marriage status, qualifications and gender with sportsmanship, altruism and civic virtue. This research demonstrates the existence of OCB among Iranian nurses that are essential in developing patient - oriented behavior. The results can be used to develop further nursing management strategies for enhancement of OCB. Finally, the present study indicates new possibilities for future researches such as analysis and comparison of OCB between different hospitals and how nursing policy-makers can enhance these behaviors in Iranian hospitals.

DETECTION AND CLASSIFICATION OF POLE-LIKE OBJECTS FROM MOBILE MAPPING DATA

K. Fukano

2015-08-01

Full Text Available Laser scanners on a vehicle-based mobile mapping system can capture 3D point-clouds of roads and roadside objects. Since roadside objects have to be maintained periodically, their 3D models are useful for planning maintenance tasks. In our previous work, we proposed a method for detecting cylindrical poles and planar plates in a point-cloud. However, it is often required to further classify pole-like objects into utility poles, streetlights, traffic signals and signs, which are managed by different organizations. In addition, our previous method may fail to extract low pole-like objects, which are often observed in urban residential areas. In this paper, we propose new methods for extracting and classifying pole-like objects. In our method, we robustly extract a wide variety of poles by converting point-clouds into wireframe models and calculating cross-sections between wireframe models and horizontal cutting planes. For classifying pole-like objects, we subdivide a pole-like object into five subsets by extracting poles and planes, and calculate feature values of each subset. Then we apply a supervised machine learning method using feature variables of subsets. In our experiments, our method could achieve excellent results for detection and classification of pole-like objects.

Full Text Available It is necessary to establish in the installed equipment, operating conditions and quality specifications in the purification of furfural produced in Cuba. To do this some literature review and experiments are carried out. The approved batches by the quality control are quantified as well as the heat and evaporation losses and the impact on workers health. Energy management is performed by identifying electricity as the energy source of higher consumption. Some measures are applied like coating the evaporator portions that are required together with condenser modification and improvement of the room ventilation. As a result it was shown that it is possible to purify the Cuban furfural in the installed equipment, the process efficiency increases in 5,5 %, the evaporation losses decrease and non-acceptance by quality control drops. If the imported furfural is replaced by the Cuban are saved about 39 000 • per year production.

Alzheimer disease (AD) is the most common cause of dementia. In regards to the world's aging population, control and treatment of AD will be one of the major concerns of global public health in the next century. Alzheimer disease was not mentioned with the same phrase or its equivalent in traditional medical texts. The main of present paper was to investigate symptoms and causes of alzheimer disease from the view point of Iranian traditional medicine. In this qualitative study, we searched reliable sources of Iranian traditional medicine such as Canon of Medicide by Avicenna (Al-Quanon fi- tibb), Aghili cure by Aghili's (Molajat-E-aghili), Tib-E-Akbari, Exire -E-Aazam and Sharh-E-Asbab and some reliable resources of neurology were probed base on keywords to find a disease that had the most overlap in terms of symptoms with alzheimer disease. By taking from the relevant materials, the extracted texts were compared and analyzed. Findings showed that alzheimer disease has the most overlap with Nesyan (fisad-e-zekr, fisad-e-fekr and fisad-e-takhayol) symptoms in Iranian traditional medicine. Although this is not a perfect overlap and there are causes, including coldness and dryness of the brain or coldness and wetness that could also lead to alzheimer disease according to Iranian traditional medicine. According to Iranian traditional medicine, The brain dystemperement is considered the main causes of alzheimer disease. By correcting the brain dystemperement, alzheimer can be well managed. This study helps to suggest a better strategy for preventing and treating alzheimer in the future.

Nineteen new lightcurves of 16 Psyche are presented along with a pole orientation derived using two independent methods, namely, photometric astrometry and magnitude-amplitude-shape-aspect. The pole orientations found using these two methods agree to within 4 deg. The results from applying photometric astrometry were prograde rotation, a sidereal period of 0.1748143 days + or - 0.0000003 days, and a pole at longitude 223 deg and latitude +37 deg, with an uncertainty of 10 deg, and, from applying magnitude-amplitude-shape-aspect a pole at 220 + or - 1 deg, +40 + or - 4 deg, and a modeled triaxial ellipsoid shape (a greater than b greater than c) and a/b = 1.33 + or - 0.07. The discrepancy between the high-pole latitude found here and the low latitudes reported by Lupishko et al. (1982) and Zhou and Yang (1982) is discussed.

We propose a current superimposition variable flux reluctance motor for a traction motor of electric vehicles and hybrid electric vehicles, which consists of 10 salient poles in the rotor and 12 slots in the stator. However, iron losses of this motor in high rotation speed ranges is large because the number of salient poles is large. In this paper, we propose a current superimposition variable flux reluctance motor that consists of 8 salient poles and 12 slots. The characteristics of the 10-pole-12-slot and 8-pole-12-slot current superimposition variable flux reluctance motors are compared using finite element analysis under vector control.

Despite all the knowledge already gathered, the picture of somatic genetic changes in colorectal tumorigenesis is far from complete. Recently, germline and somatic mutations in the exonuclease domain of polymerase epsilon, catalytic subunit (POLE) gene have been reported in a small subset of microsatellite-stable and hypermutated colorectal carcinomas (CRCs), affecting the proofreading activity of the enzyme and leading to misincorporation of bases during DNA replication. To evaluate the role of POLE mutations in colorectal carcinogenesis, namely in advanced CRC, we searched for somatic mutations by Sanger sequencing in tumor DNA samples from 307 cases. Microsatellite instability and mutation analyses of a panel of oncogenes were performed in the tumors harboring POLE mutations. Three heterozygous mutations were found in two tumors, the c.857C>G, p.Pro286Arg, the c.901G>A, p.Asp301Asn, and the c.1376C>T, p.Ser459Phe. Of the POLE-mutated CRCs, one tumor was microsatellite-stable and the other had low microsatellite instability, whereas KRAS and PIK3CA mutations were found in one tumor each. We conclude that POLE somatic mutations exist but are rare in advanced CRC, with further larger studies being necessary to evaluate its biological and clinical implications. © 2017 The Authors.

Development of a multi-pole magnetorheological brake

International Nuclear Information System (INIS)

Shiao, Yaojung; Nguyen, Quang-Anh

2013-01-01

This paper presents a new approach in the design and optimization of a novel multi-pole magnetorheological (MR) brake that employs magnetic flux more effectively on the surface of the rotor. MR brakes with conventional single ring-type electromagnetic poles have reached the limits of torque enhancement. One major reason is the limitation of the magnetic field strength within the active area of the MR fluid due to the geometric constraints of the coil. The multi-pole MR brake design features multiple electromagnetic poles surrounded by several coils. As a result, the active chaining areas for the MR fluid are greatly increased, and significant brake torque improvement is achieved. The coil structure, as a part of the stator, becomes flexible and customizable in terms of space usage for the winding and bobbin design. In addition, this brake offers extra options in its dimensions for torque enhancement because either the radial or the axial dimensions of the rotor can be increased. Magnetic circuit analysis was conducted to analyze the effects of the design parameters on the field torque. After that, simulations were done to find the optimal design under all major geometric constraints with a given power supply. The results show that the multi-pole MR brake provides a considerable braking torque increase while maintaining a compact and solid design. This is confirmation of its feasibility in actual braking applications. (paper)

Captive breeding is a widespread conservation strategy, yet such programs rarely include empirical genetic data for assessing management assumptions and meeting conservation goals. Cuban Amazon parrots (Amazona leucocephala) are considered vulnerable, and multiple on-island captive populations have been established from wild-caught and confiscated individuals of unknown ancestry. Here, we used mitochondrial haplotypic and nuclear genotypic data at 9 microsatellite loci to quantify the extent and distribution of genetic variation within and among captive populations in Zapata Swamp and Managua, Cuba, and to estimate kinship among breeders (n = 88). Using Bayesian clustering analysis, we detected 2 distinct clusters within the Zapata population, one of which was shared with Managua. Individuals from the cluster unique to Zapata possessed mitochondrial haplotypes with affinities to Cuban subspecies (A. l. leucocephala, A. l. palmarum); the shared cluster was similar, but also included haplotypes closely related to the subspecies restricted to Cayman Brac (A. l. hesterna). Overall mean kinship was low within each captive population (-0.026 to -0.012), with 19 and 11 recommended breeding pairs in Zapata and Managua, respectively, ranked according to mean kinship and informed by molecular sexing. Our results highlight the importance of understanding population history within ex situ management programs, while providing genetic information to directly inform Cuban parrot conservation. © The American Genetic Association 2015.

The Iranian nuclear crisis

International Nuclear Information System (INIS)

Le Guelte, Georges

2006-01-01

This article proposes an overview of the Iranian nuclear issue. The author first recalls that Iran has launched a nuclear program during the 1970's with the objective of building several nuclear power stations for electricity production. He evokes contracts signed by the Shah and the consequences of the Islamic revolution after which Iranian governments thought it was absurd to leave these constructions unfinished. The author outlines the several mistakes made by Western countries in their relationship with Iran, and those made by Iran (development of hidden nuclear program for example), which altogether leaded to the present crisis. The author discusses some legal aspects, notably the fact that Iran signed very early the NPT (non proliferation Treaty) as other countries who posses nuclear weapons, did not. He outlines the political challenges at different scales, regional as well as international, and finally discusses the uncertain perspectives

1996-01-01

Thermal and epithermal non-destructive activation analyses have been performed on samples of final molasses from 14 different sugar factories , covering the most important regions in Cuba. From the first measurement after irradiation at the Triga Mark reactor (VTT), the concentration of more than 15 elements is reported. The almost constant elemental composition shows that they can be used equally for different purposes as animal foodstuff and for the manufacture of biotechnological products. This work is part of a research project developed in order to establish a complete characterization of Cuban sugar molasses. (author). 7 refs., 2 tabs

Full Text Available This work leaves from the theoretical and empiric systematizing that shows the necessity to investigate how it has evolved and what factors they have conditioned the behavior of the methodological work direction in the education municipal level. The basic budgets of the educational are approached that serve of referents for the analysis of the relationships of the organizational functional levels of the methodological work. The study is carried out in the period 1959-2017, starting in 1959 as an important milestone in the conception of the Cuban educational system. When the Revolution triumphed there were two conceptions of Education, in Cuban educational practice, on the one hand the abandoned national education system, essentially pragmatic, totally incongruous and on the other the aspirations of the Revolutionary Government, which had been forged in the revolutionary struggle between 1953 and 1959.

Fibreglass as an alternative to wood poles : Transmission and distribution poles and crossarms : use of fiber reinforced composite materials for overhead electric utility lines

Wiles, J.R. [Shakespeare Composites and Electronics, Newberry, SC (United States)

2002-07-01

For over thirty years, Shakespeare Composites and Electronics has manufactured fiberglass composite lighting and utility poles, as well as being the number one maker of composite crossarms. Composite poles have a few advantages, such as being lightweight, they do no rust, are woodpecker and termite resistant, use no harmful chemicals, and have long life. A chart displaying the comparative pole weights is presented. The key design factors of fiberglass composite utility poles are: pole diameter, fiberglass type and wind angle, layers (thickness) of fiberglass, resin type and formulation, resin mix consistency, cure cycle and maximum curing temperature, and others. Two charts were also displayed presenting 40 feet class 4 pole bending strengths and 40 feet class 2 pole bending strengths. The author indicated that composite poles have a better strength consistency than wood, while being as consistent as steel and prestressed concrete. The design is based on an overload factor of safety of 2.5 for numerous installations. Some of the analytical methods used include mechanical testing, finite element modeling, and thermal analysis. The author describes in detail the concerns associated with attachments. Coating consists of a system of ultra violet blockers in the resin followed by an added resin rich polyester veil outer surface. In addition, there is a proprietary coating process with additional ultra violet blockers. Quality control is effected at the plant. The weathering system lasts 80 years. figs.

Full Text Available Objectives: The present study aims to investigate the international status and visibility of Iranian journals which have been indexed in Journal Citation Reports (JCR. Accordingly, the number of international papers, citations and editorial board members of each journal was studied. Moreover, various measures were utilized to compare the quality of Iranian journals with their international counterparts. Method: Current paper applied scientometric research method. A total of 16471 papers which published in 38 Iranian journals and indexed by the JCR 2013 were selected as the population of the study. Web of Science (WoS, JCR and journals’ website were used for data gathering. Results: Results of the study revealed that foreign researchers have published 34.8% of papers published in Iranian ISI journals. Moreover, only 30.6% of citations to Iranian ISI journals have been received from foreign papers or Iranian internationally collaborative papers. The results showed that Iranian researchers accounted for 66.4% of editorial board member of all studied journals, while foreign researchers only occupied 33.6% of the editorial board positions. Based on the findings, only two Iranian journals have impact factors above the median of the journals in the disciplinary category areas in which they are classified in JCR. Furthermore, only 8 Iranian journals have ever been placed in the 1st and 2nd quartile of journals of the same field in the JCR. Findings also showed that 36 out of the 38 Iranian journals have mostly cited by journals with higher median impact factors than cited journals. Conclusion: The findings indicate that the share of international papers, citations and editorial board memberships is low in Iranian ISI journals. Moreover, Iranian journals’ impact factor was below of those of the leading journals.

Full Text Available Different genres of underground music are important issues in Iranian youth culture. The purpose of this research was to study masculinity in Iranian- Persian rap music. Therefore, Persian rap music as a part of Iranian popular culture, between 2001 and 2011 was analyzed. We used qualitative research approach. The main method used in this study, was "Constructive Grounded Theory ". So instead of using existing theories as a theoretical framework, the researcher sought to generate local theory from research field. Thus, using theoretical sampling, data compiled from various sources. The multiple data collection techniques such as interviews, observation, online observation, collecting documents and texts were used. Then all the data was coded with using open, axial and selective coding methods. Finally, 62 concepts and 16 categories derived from data and "plural form of masculinity in Iranian-Persian rap music" was defined as the core category. Then according to paradigmatic model, "Substantive Theory" emerged from the data, was presented as "story" and "visual model". Finally seven questions of Strauss and Corbin about the experience in research has been assessed to evaluating research.

A reformulation of inflationary model analyses appeared recently, in which inflationary observables are determined by the structure of a pole in the inflaton kinetic term rather than the shape of the inflaton potential. We comprehensively study this framework with an arbitrary order of the pole taking into account possible additional poles in the kinetic term or in the potential. Depending on the setup, the canonical potential becomes the form of hilltop or plateau models, variants of natural inflation, power-law inflation, or monomial/polynomial chaotic inflation. We demonstrate attractor behaviors of these models and compute corrections from the additional poles to the inflationary observables.

We report a field-pole high-temperature superconductor (HTS) magnet designed for 1 MW-class motor for propulsion. The field pole is assembled to the rotor of the radial-type motor. Each field pole is composed of HTS-Bi2223 tape wound into coils which have been piled up as a double pancake coils. In the design concept of the motor, we employ field poles without iron core. We prepared the test field-pole coil, whose dimension is smaller than the designed one for 1 MW, and tested its performances after cooling under self-field and external magnetic field. We verified the operation with the minimum bend radius of the coils required in the motor design, while keeping an optimal current which is lower than the critical current of the field-pole coil. The test HTS field poles were successfully cooled down and operated under a magnetic field ranging up to 5 T. We report the results of the test field-pole coil and the manufacture of a practical racetrack coil with Bi2223 and discuss the adaptability to 1 MW-class motors.

Research highlights: → Mathematical model represents a power system which consists of synchronous machine connected to infinite bus through transmission line. → Power system stabilizer was designed based on optimal pole shifting controller. → The system performances was tested through load disturbances at different operating conditions. → The system performance with the proposed optimal pole shifting controller is compared with the conventional pole placement controller. → The digital simulation results indicated that the proposed controller has a superior performance. -- Abstract: Power system stabilizer based on optimal pole shifting is proposed. An approach for shifting the real parts of the open-loop poles to any desired positions while preserving the imaginary parts is presented. In each step of this approach, it is required to solve a first-order or a second-order linear matrix Lyapunov equation for shifting one real pole or two complex conjugate poles, respectively. This presented method yields a solution, which is optimal with respect to a quadratic performance index. The attractive feature of this method is that it enables solutions of the complex problem to be easily found without solving any non-linear algebraic Riccati equation. The present power system stabilizer is based on Riccati equation approach. The control law depends on finding the feedback gain matrix, and then the control signal is synthesized by multiplying the state variables of the power system with determined gain matrix. The gain matrix is calculated one time only, and it works over wide range of operating conditions. To validate the power of the proposed PSS, a linearized model of a simple power system consisted of a single synchronous machine connected to infinite bus bar through transmission line is simulated. The studied power system is subjected to various operating points and power system parameters changes.

The major difference between Iranian traditional medicine and allopathic medicine is in the application  of  evidence  and  documents.  In  this  study,  criteria  for  evidence-based  practice  in  Iranian traditional medicine and its rules of practice were studied. The experts' views were investigated through in- depth, semi-structured interviews and the results were categorized into four main categories including Designing clinical questions/clinical question-based search, critical appraisal, resource search criteria and clinical prescription appraisal. Although the application of evidence in Iranian traditional medicine follows Evidence Based Medicine (EBM) principles but it benefits from its own rules, regulations, and criteria that are compatible with EBM.

Antimicrobial activity of Iranian propolis and its chemical composition

Yaghoubi M.J.

2007-04-01

Full Text Available The objective of this study was to investigate the antimicrobial activity of ethanol extract of Iranian propolis on some microorganisms using disc diffusion method. The chemical composition of the propolis was also investigated using thin layer chromatography and spectrophotometric methods. Ethanol extract of propolis showed activity only against Gram-positives and fungi, whereas no activity was observed against Gram-negatives. Thin layer chromatography screening revealed the presence of pinocembrine, caffeic acid, kaempferol, phenethyl caffeate, chrysin, and galangin in Iranian propolis. The total flavonoid and phenolic contents were 7.3% and 36%, respectively, which suggests that the strong antimicrobial activity of Iranian propolis may be due to high levels of phenolic and flavonoid compounds.

Various methods have been put into practice for the conventional two-dimensional pole configuration using a single line in three-dimensional electrical prospecting. Pole configuration effective for the three-dimensional exploration has not been investigated. This paper describes synthetic focused array using four pairs of guarded poles based on pole-pole array potential data in the case of arrangement of measuring points on a grid. Results of the numerical simulation are also described. For the focused array, laterolog of electrical logging is applied to the surface prospecting. Directivity can be given to the current from the main pole by controlling the current from guarded pole. It was found from the simulation that the resistivity anomaly is concentrated directly on the embedded ball for the focused array rather than for the pole-pole array. It was also found that two conductive balls can be clearly separated for the focused array rather than for the dipole-dipole array. Accordingly, it was considered that results approximating the original structures can be obtained by analyzing using the both arrays. 5 refs., 6 figs.

It is demonstrated that the amplitude for electron--hydrogen-atom forward scattering has the third-order pole at the point E = -13.6 eV, E being the energy of the incident electron. The coefficients which characterize the pole are calculated exactly. The invalidity of the Born approximation is proved. The contribution of the pole singularity to the dispersion relation for the scattering amplitude is discussed

Live imaging of spindle pole disorganization in docetaxel-treated multicolor cells

2007-01-01

Treatment of cells with docetaxel at low concentrations induces aberrant bipolar spindles of which two centrosomes stay at only one pole, and also induces multipolar spindles. To gain insight into the relations between centrosome impairment and structural defects of the spindle, live-cell imaging was performed on a human MDA Auro/imp/H3 cell line in which centrosomes/mitotic spindles, nuclear membrane and chromatin were simultaneously visualized by fluorescent proteins. In the presence of docetaxel at IC 50 concentration, the centrosomes did not segregate, and multiple aster-like structures ectopically arose around the disappearing nuclear membrane. Those ectopic structures formed an acentrosomal pole opposing to the two-centrosomes-containing pole. In late metaphase, one pole often fragmented into multiple spindle poles, leading multipolar division. These results suggest that spindle pole fragility may be induced by centrosome impairment, and collapse of the pole may contribute to induction of aneuploid daughter cells

2017-04-01

Full Text Available Along the History of the Cuban education, the teaching and the learning of the life and work of the historical personalities has constituted a priority. However, the tendency has prevailed to alone to approach in the different teaching levels the historical personalities from a political-military focus, without conceiving an integrative treatment that embraces other spheres of the social activity. Equal limitations exist in reconstructing the historical context where the same ones were developed and to analyze their narrow one with the diverse social sectors that accompanied her. The present article seeks to demonstrate the necessity to transform the treatment of the historical personalities at the present time.

Full Text Available Automatic semantic interpretation of street furniture has become a popular topic in recent years. Current studies detect street furniture as connected components of points above the street level. Street furniture classification based on properties of such components suffers from large intra class variability of shapes and cannot deal with mixed classes like traffic signs attached to light poles. In this paper, we focus on the decomposition of point clouds of pole-like street furniture. A novel street furniture decomposition method is proposed, which consists of three steps: (i acquirement of prior-knowledge, (ii pole extraction, (iii components separation. For the pole extraction, a novel global pole extraction approach is proposed to handle 3 different cases of street furniture. In the evaluation of results, which involves the decomposition of 27 different instances of street furniture, we demonstrate that our method decomposes mixed classes street furniture into poles and different components with respect to different functionalities.

Iranian Activities in Afghanistan: Constructive or Destructive Attitude?

Directory of Open Access Journals (Sweden)

Josef Kraus

2012-12-01

Full Text Available Afghanistan is still not a stable state with strong central government controlling the whole state territory even after eleven years since American intervention and following the pursuit of reconstruction by allied forces. One of the main causes of this situation consists in interferences of foreign powers, which have their own particular and often mutually incompatible interests in Afghanistan. One of the most important external powers in the country is Iran. Therefore, Iranian involvement in Afghanistan is the main topic of this text. The main goal of this article is to identify and interpret major methods of Iranian enforcement of its plans in Afghanistan and also the characterization of those plans. The important issue of this text is also an understanding of effects of Iranian activities in Afghanistan and whether those actions have positive or rather negative contribution.

Impacts of international sanctions on Iranian pharmaceutical market.

Iran in recent decade faced several regional and international sanctions in foreign trade, financial and banking services. Iran national pharmaceutical industry has always played a major role in providing medicines to the Iranian patients. However, following the sanctions it has faced profound difficulties for importing of both finished products and pharmaceutical raw materials. Although medicines are exempted from sanctions, due to restriction on money transaction and proper insurance Iranian pharmaceutical companies have to pay cash in advance for imports of medicines and raw materials or to secure offshore funds at very high risks. Current situation in Iran pharmaceutical market confirms that the sanctions against Iran are affecting ordinary citizens and national health sector which resulted to reduction of availability of lifesaving medicines in the local market and has caused increasing pain and suffering for Iranian patients.

Many studies presented information on stress, effects of coping strategies, and job satisfaction of nurses within health setting. We aimed to identify and describe nursing stresses, coping strategies and job satisfaction of Iranian nurses who are working or worked in different wards. In this review, we studied peer-reviewed journal articles on the field of stress, coping strategies and job satisfaction in nursing practice, especially Iranian nurses, which were published between 2000 and 2013. In this regard, we searched databases of PubMed, Elsevier, Google, BMJ, PMC, and MEDLINE. The majority of the studies (60%) had analyzed the effect of coping strategies, experiences and perception of job-related stresses in Iranian nurses working in hospitals. In some of the reviewed studies (60%), the majority of the samples enrolled Iranian nurses. Forty percent of studies selected a maximum sample size of 565 (44%) participants in 2011. Nursing stress scale employed at 30% of the studies was the most commonly used strategy. This reviewed studies also revealed a combined measurement (60% of studies), based on categorical stress measurement, effects of coping strategies, and job satisfaction methods. Three studies explored the relationship between job stress and job satisfaction. For instance, the majority (74.4%) of nurses reported job satisfaction. Effect of coping strategies and job satisfaction on Iranian nurses is a well-accepted issue and has important positive outcomes on several areas of health discipline.

A compact high-field superconducting quadrupole magnet was designed and built with poles made of the rare-earth metal holmium. The magnet is intended for use in superconducting coupled-cavity linear accelerators where compact high-field quadrupoles are needed, but where the use of permanent magnets is ruled out because of trapped-flux losses. The magnet has a clear bore diameter of 1.8 cm, outside diameter of 11 cm, length of 11 cm, and pole tip length of 6 cm. The effect of using holmium, a material with a higher saturation field than iron, was investigated by replacing poles made of iron with identical poles made of holmium. The magnet was operated at a temperature of 4.2 K and reached a peak quadrupole field gradient of 355 T/m, a 10% increase over the same magnet with iron poles. This increase in performance is consistent with calculations based on B-H curves that were measured for holmium at 4.2 K. (orig.).

Effect of materials and manufacturing on the bending stiffness of vaulting poles

Davis, C. L.; Kukureka, S. N.

2012-09-01

The increase in the world record height achieved in pole vaulting can be related to the improved ability of the athletes, in terms of their fitness and technique, and to the change in materials used to construct the pole. For example in 1960 there was a change in vaulting pole construction from bamboo to glass fibre reinforced polymer (GFRP) composites. The lighter GFRP pole enabled the athletes to have a faster run-up, resulting in a greater take-off speed, giving them more kinetic energy to convert into potential energy and hence height. GFRP poles also have a much higher failure stress than bamboo, so the poles were engineered to bend under the load of the athlete, thereby storing elastic strain energy that can be released as the pole straightens, resulting in greater energy efficiency. The bending also allowed athletes to change their vaulting technique from a style that involved the body remaining almost upright during the vault to one where the athlete goes over the bar with their feet upwards. Modern vaulting poles can be made from GFRP and/or carbon fibre reinforced polymer (CFRP) composites. The addition of carbon fibres maintains the mechanical properties of the pole, but allows a reduction in the weight. The number and arrangement of the fibres determines the mechanical properties, in particular the bending stiffness. Vaulting poles are also designed for an individual athlete to take into account each athlete’s ability and physical characteristics. The poles are rated by ‘weight’ to allow athletes to select an appropriate pole for their ability. This paper will review the development of vaulting poles and the requirements to maximize performance. The properties (bending stiffness and pre-bend) and microstructure (fibre volume fraction and lay-up) of typical vaulting poles will be discussed.

2014-01-01

There is considerable investment in timber utility poles worldwide, and there is a need to examine the structural reliability and probability based management optimisation of these power distribution infrastructure elements. The work presented in this paper builds on the existing studies in this area through assessment of both treated and untreated timber power poles, with the effects of deterioration and network maintenance incorporated in the analysis. This more realistic assessment approach, with deterioration and maintenance considered, was achieved using event-based Monte Carlo simulation. The output from the probabilistic model is used to illustrate the importance of considering network maintenance in the time-dependent structural reliability assessment of timber power poles. Under wind load, treated and untreated poles designed and maintained in accordance with existing Australian standards were found to have similar failure rates. However, untreated pole networks required approximately twice as many maintenance based pole replacements to sustain the same level of reliability. The effect of four different network maintenance strategies on infrastructure performance was also investigated herein. This assessment highlighted the fact that slight alterations to network maintenance practices can lead to significant changes in performance of timber power pole networks. - Highlights: • A time-dependent structural reliability model was developed for timber power poles. • Deterioration and network maintenance were incorporated into this event based model. • Network maintenance had a significant impact on power pole wind vulnerability. • Treated and untreated poles designed to Australian standards had similar reliability. • Minor alterations to maintenance strategies had large effects on network performance

A method is described which allows to calculate the crystallite orientation distribution in polycrystalline material, from direct pole figures data of its crystallographic planes (Roe's Method). The programme was applied to (1010), (0002), (1011) and (1120) complete pole figures data for a commercial, thin sheet Zircaloy-4 tubing specimen. A semi-automatic Rigaku-Denki texture goniometer, which scans the reciprocal lattice sphere pointwise outputting the data in a punched tape, was used to obtain the pole figures. This is consistent with the results obtained through direct conclusion from the pole figures. (author)

Full Text Available Introduction. Dental stones are widely used in dentistry and the success or failure of many dental treatments depend on the accuracy of these gypsums. The purpose of this study was the evaluation of Iranian dental stones and comparison between Iranian and foreign ones. In this investigation, consistency and setting time were compared between Pars Dendn, Almas and Hinrizit stones. The latter is accepted by ADA (American Dental Association. Consistency and setting time are 2 of 5 properties that are necessitated by both ADA specification No. 25 and Iranian Standard Organization specification No. 2569 for evaluation of dental stones. Methods. In this study, the number and preparation of specimens and test conditions were done according to the ADA specification No. 25 and all the measurements were done with vicat apparatus. Results. The results of this study showed that the standard consistency of Almas stone was obtained by 42ml water and 100gr powder and the setting time of this stone was 11±0.03 min. Which was with in the limits of ADA specification (12±4 min. The standard consistency of Pars Dandan stone was obrianed by 31ml water and 100 gr powder, but the setting time of this stone was 5± 0.16 min which was nt within the limits of ADA specification. Discussion: Comparison of Iranian and Hinrizit stones properties showed that two probable problems of Iranian stones are:1- Unhemogrnousity of Iranian stoned powder was caused by uncontrolled temperature, pressure and humidity in the production process of stone. 2- Impurities such as sodium chloride was responsible fo shortening of Pars Dendens setting time.

Comparative Investigation on the Performance of Modified System Poles and Traditional System Poles Obtained from PDC Data for Diagnosing the Ageing Condition of Transformer Polymer Insulation Materials

Full Text Available The life expectancy of a transformer is largely depended on the service life of transformer polymer insulation materials. Nowadays, several papers have reported that the traditional system poles obtained from polarization and depolarization current (PDC data can be used to assess the condition of transformer insulation systems. However, the traditional system poles technique only provides limited ageing information for transformer polymer insulation. In this paper, the modified system poles obtained from PDC data are proposed to assess the ageing condition of transformer polymer insulation. The aim of the work is to focus on reporting a comparative investigation on the performance of modified system poles and traditional system poles for assessing the ageing condition of a transformer polymer insulation system. In the present work, a series of experiments have been performed under controlled laboratory conditions. The PDC measurement data, degree of polymerization (DP and moisture content of the oil-immersed polymer pressboard specimens were carefully monitored. It is observed that, compared to the relationships between traditional system poles and DP values, there are better correlations between the modified system poles and DP values, because the modified system poles can obtain much more ageing information on transformer polymer insulation. Therefore, the modified system poles proposed in the paper are more suitable for the diagnosis of the ageing condition of transformer polymer insulation.

Choice of wood poles can reduce greenhouse gases

Energy Technology Data Exchange (ETDEWEB)

Sedjo, R. A.

2002-07-01

The first, second and third assessment reports on climate change of the Intergovernmental Panel on Climate Change (IPCC) are reviewed in an effort to highlight results of past studies on the total life cycle energy utilization of wood products compared with the use of substitute materials such as steel, concrete, bricks and aluminum. Without exception, all studies found that the total energy requirements associated with wood materials are substantially lower than those of other commonly substituted materials. For example, it has been clearly demonstrated that wooden poles are more environmentally benign than concrete or steel poles with regard to their energy utilization and their potential to contribute to atmospheric carbon dioxide emissions. An estimate to convert wood poles to steel poles showed that while the greenhouse gas emissions associated with pole conversion were modest compared to the national total, they were nevertheless a significant percentage of US annual emission (approximately 2.8 per cent of annual US total of 5.28 billion tons of carbon dioxide). These studies provide empirical confirmation of the concept that substitution of high energy-intensive materials for low-energy-using wood materials contributes substantially to the overall increase of carbon dioxide emissions through their overall higher energy requirements.

Reducing the effects of traffic accidents over the occupants is a major objective of collision attempts. Impacts between the car and the pole are very dangerous for the physical integrity of the car’s occupants. To minimalize the effects of such events on the passengers of a vehicle, a whole series of efforts by both designers and experienced engineers led to increasingly the vehicles safety. The main aim of these paper is to quantify the influences over the car passengers of loads involved by car against pole collisions using the same car model at different speeds. Also, this kind on occupant influences were study using a small car model. Other goal of the paper was the study of the cars stiffness in frontal collision against the pole. The paper’s experimental results were obtained by support of DSD, Dr. Steffan Datentechnik GmbH - Linz, Austria. The described tests were performed in full test facility of DSD Linz, in “Easter 2016 PC-Crash Seminar”. Cars accelerations, velocities, rotations angles after pole impact were registered and discussed. The novelty of the paper consists in studies referred for the same car model involved in car against pole collisions at different impact speeds. Paper’s conclusions can be future used for car safety improvement.

The energy crisis and climate change give new importance to sustainable architecture which reduces the negative impacts that buildings can have on the environment. In ancient times, architects did not have access to modern equipment and had to use natural energies to provide pleasant indoor conditions. Iran has various climatic zones and Iranian traditional architecture relied on a variety of solutions to provide for human comfort. The aim of this study is to present those solutions used in traditional Iranian architecture. This paper presents the use of the energy of the earth depth and other methods such as Syzan, a cellar, Shvadan, pool house, Zmhryr in addition to the sunken garden, which taps geothermal energy by constructing a courtyard lower than street level. This document showed that traditional Iranian architectural strategies are efficient in providing sustainable buildings and could be applied in the design of new construction.

Full Text Available Abstract Background We describe corneal endothelial cell density and morphology in normal Iranian eyes and compare endothelial cell characteristics in the Iranian population with data available in the literature for American and Indian populations. Methods Specular microscopy was performed in 525 eyes of normal Iranian people aged 20 to 85 years old. The studied parameters including mean endothelial cell density (MCD, mean cell area (MCA and coefficient of variation (CV in cell area were analyzed in all of the 525 eyes. Results MCD was 1961 ± 457 cell/mm2 and MCA was 537.0 ± 137.4 μm2. There was no statistically significant difference in MCD, MCA and CV between genders (Student t-test, P = 0.85, P = 0.97 and P = 0.15 respectively. There was a statistically significant decrease in MCD with age (P r = -0.64. The rate of cell loss was 0.6% per year. There was also a statistically significant increase in MCA (P r = 0.56 and CV (P r = 0.30 from 20 to 85 years of age. Conclusion The first normative data for the endothelium of Iranian eyes seems to confirm that there are no differences in MCD, MCA and CV between genders. Nevertheless, the values obtained in Iranian eyes seem to be different to those reported by the literature in Indian and American populations.

Role of diet on colorectal cancer (CRC) has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns in Iran. The objective of this study was to determine the association between Iranian dietary patterns and CRC. This case-control study was conducted in four hospitals in Tabriz City of Iran including 414 participants aged 35-75 years:207 cases with CRC confirmed by pathology and colonoscopy findings were selected and 207 controls free of neoplastic conditions and diet-related chronic diseases (from the same hospital at the same period for the cases). Dietary data were assessed using a 123-item semi-quantitative food frequency questionnaire. Two dietary patterns were found by using of Principal Component Analysis (PCA) method;"Healthy pattern"and "Iranian pattern". Multivariate logistic regression analysis was used to estimate adjusted odds ratios (OR) for relationship between dietary patterns and colorectal cancer. After adjusting for confounding factors, the Iranian dietary pattern was significantly associated with an increased odds of colorectal cancer (OR= 1.46; 95% Confidenec Interval (CI)=1.05-2.19) while a reduced odds of colorectal cancer was observed with the Healthy dietary pattern (OR=0.18; 95% CI= 0.091-0.47). Iranian dietary pattern (IDP) seems to increase the odds of colorectal cancer and protective effect of Healthy dietary pattern.

Full Text Available The collapse of the USSR affected the Russian-Iranian relations, governed by bilateral agreements during several centuries. The emergence of “new” independent states in the region, such as Azerbaijan, Kazakhstan and Turkmenistan, changed the geopolitical situation and put a question of the legal status of the Caspian Sea. Russian-Persian and Soviet-Iranian agreements had a centuries-old tradition but they did not draw up a legal status of the Caspian Sea or clarify the procedures of subsursafe management. Those agreements governed only laid down rules of navigation and fishery, without touching the issues of oil and gas field exploration, production and transportation, including pipelines on the floor of the Caspian Sea. It did not fit political and economic interests of Azerbaijan, Kazakhstan and Turkmenistan and stimulate them to unilateral actions. Russia and Iran in turn insisted on saving the former rules and agreements. The absence of Convention on legal status of the Caspian Sea introduced uncertainty in the principles of oil and gas development and export, pushing Caspian countries toward making unilateral decisions. Russia and Iran kept close positions, insisting on following the former agreements. The other Caspian countries did not support that position and adopted a policy aimed at division of the Caspian Sea and asserting a certain control over its hydrocarbons. Close Russian and Iranian positions on legal status of the Caspian Sea became a strong deterrent for Caspian countries to let them divide the sea into national sectors and launch pipeline plans on the floor of the Caspian Sea. As the result Russian and Iranian relations had stabilizing effect in the Caspian region. At the same time, the Russian Federation aimed at following a flexible policy, taking into account the interests of the other Caspian countries.

Full Text Available Iranian learners at all levels of education (primary, secondary and tertiary face a number of constraints in their studies due to restriction of educational system, cultures, upbringing and expectations of society. Based on this premise the researchers would like to explore the degrees of autonomy as practiced by selected Iranian postgraduate students studying at three premier public universities in Malaysia. Data were gathered using the Learner Autonomy Profile (LAP developed by Confessore & Confessore (1992.  The findings reveal that these Iranian postgraduate students do practice autonomy and know how to apply positive coping strategies in their studies; thus indicating positive contradiction from the normal expectations of Iranian learners’ performance in relation to autonomy. The paper concludes with the impacts and implications of the findings.

2008-03-01

Although greater emphasis has been placed on leadership skills in nursing management in the last decade, the concepts are often confused or used erroneously by Iranian nurses. At the same time we have observed that wide variations in nurses' clinical practice appeared to be related to the presence or absence of leadership skills among senior nurses. To begin to identify the concepts used for expressing leadership in nursing within the Iranian cultural context. A qualitative approach was adopted using content analysis of semi-structured interviews carried out with 10 nurse managers from hospitals in Teheran. The data were analysed using the constant comparative method. Fifty-five primary codes were identified from the respondents' experiences and from these three main themes were abstracted for describing the leadership concept. These were 'personality traits', 'being a model', and 'being a spiritual guide for the nursing profession'. Implementing the culture of patient safety and dignity needs leadership. From Iranian nurse managers' perspectives a leader as a spiritual guide should empower nurses spiritually; it means he/she has a vision for nursing; has clear and explicit objectives; and has a commitment to nursing. Nurses who are confident about the underlying concepts of leadership in their culture can help to adapt nursing to an ever-changing healthcare environment.

2011-01-01

Full Text Available Pole placement problems are especially important for disturbance rejection and stabilization of dynamical systems and regarded as algebraic inverse eigenvalue problems. In this paper, we propose gain formulae of state feedback through PID-elements to achieve desired pole placement for a delay-free LTI system with single input. Real and complex stable poles can be assigned with the proposed compact gain formulae. Numerical examples show that our proposed gain formulae can be used effectively resulting in very satisfactory responses.

Pole solutions for flame front propagation

Kupervasser, Oleg

2015-01-01

This book deals with solving mathematically the unsteady flame propagation equations. New original mathematical methods for solving complex non-linear equations and investigating their properties are presented. Pole solutions for flame front propagation are developed. Premixed flames and filtration combustion have remarkable properties: the complex nonlinear integro-differential equations for these problems have exact analytical solutions described by the motion of poles in a complex plane. Instead of complex equations, a finite set of ordinary differential equations is applied. These solutions help to investigate analytically and numerically properties of the flame front propagation equations.

Author discusses reasons for the silence on race issues, and for the historic construction of the "myth" of racial equality in this era. Then, she points at the difficulties in the studying of the presence of former slaves among the Cuban soldiers in the War of Independence, due to the absence of racial labels for the registered soldiers. She describes how the research on the theme became more local, and focused on the Cienfuegos region, in part because of Cienfuegos' extensive local archive. Then, she outlines the different approaches to research on the matter by the archives' director Orlando García Martínez, by Michael Zeuske, and by the author herself. The latter explains how she extended her archival research with oral testimonies of descendants in Cienfuegos of black soldiers, and how through examining life histories, collective biographies, and genealogies, she ascertained that the number of former slaves in the rebellious Cuban army was relatively small, but the number of free-born blacks and mulattoes was high.

This study examines the controversy surrounding the nationalization of the Anglo-Iranian Oil Company (AIOC). It traces the events leading to Iran's nationalization of the company in 1951 and details efforts to negotiate a settlement that would reconcile Iranian grievances against the AIOC with British claims for compensation. Because the British and the Iranians sought, and ultimately received, American assistance in resolving their dispute, this study places the nationalization crisis in a tripartite framework. It reveals the global as well as the regional nature of a struggle that historians have slighted, and follows this struggle to the autumn of 1954, when the American government helped to organize an international consortium to replace the AIOC. This study covers the nationalization imbroglio from a variety of angles. It draws on archives in Great Britain and the US in order to integrate British and American policy into a coherent analysis. It uses similar sources, as well as the literature on Iran, to trace the Iranian side of the story, link the nationalization crisis to earlier and subsequent events, and place it within a global context

Full Text Available Assistive technologies have always opened new horizons in human's life, posed solutions to problemsand brought relief and prosperity for human beings. Iranian judicial authorities have recently recognizedthe importance of medical technologies. Accordingly, Iranian legal system has recognized surrogacy anda surrogacy contract seems unavoidable for surrogacy to be legally valid, socially acceptable andreligiously legitimate. As a legal defense of including a typical surrogacy contract in contract law, thisreview studies the four building blocks of a valid contract: the intention and consent of parties, theirlegal capacity, the subject of the contract and its legitimacy. Discussing related Iranian Acts concerningcontracts and responsibilities of parties, the authors of the present article deal with main commitmentsand responsibilities of the parties to a typical surrogacy contract: infertile couples, surrogate, fertilityclinic or medical institute, and surrogate's husband. The authors conclude that a surrogacy contract isaccepted based on article 10 of Iranian Civil Act 1928, pose some suggestions to be included in such acontract, and emphasize that a specific Act concerning surrogacy should be approved to cover rights andlegal needs of all parties to a surrogacy contract.

High coverage of immunization is one of the indicators of good performance of health system but timely vaccination is another indicator which is associated with protective effect of vaccines. The present study aimed at evaluating the inequity in timely vaccination with a focus on inequities in timeliness by gender, birth order, parents' education and place of residence (rural or urban). A historical cohort study was conducted on children of 24-47 months of age who were living in the suburbs of big cities in Iran and were selected through stratified proportional sampling method. Only children who had vaccine cards -i.e. 3610 children -were included in data analysis. The primary outcome was age-appropriate vaccination of MMR1. Inequity was measured by Concentration Index (C) and Relative Index of Inequity (RII). Inequity indexes were calculated according to the mother and father's education, child birth order, child's sex and the family's place of residence at the time of vaccination. The overall on-time MMR1 vaccination was 70% and 54.4% for Iranians and Non-Iranians, respectively. The C index of mother and father's education for timely MMR vaccination was 0.023 and was 0.029 in Iranian children as well as 0.044 and 0.019 for non-Iranians, respectively. The C index according to child order in Iranians and Non-Iranians was 0.025 and C=0.078. With regard to children who lived in cities, the on-time vaccination was 0.36% and 0.29% higher than that in rural areas . In male children it was 0.12% and 0.14% higher than that in female children for Iranians and Non-Iranians, respectively. Timeliness MMR vaccination in Iranian children is higher than that in non-Iranian children. Regarding the existence of differences in timely vaccination rate in all Iranian and Non-Iranian children, no evidence was observed for inequity by focusing on parents' education, birth order, gender or place of residence. So, increasing timeliness of vaccination for enhancing the protective effect

A series of heterometal cubane-type clusters containing [VFe(3)S(4)](2+) and [MoFe(3)S(4)](3+,2+) cores has been prepared. Ligand substitution of [(DMF)(3)VFe(3)S(4)Cl(3)](-) affords [(Tpms)VFe(3)S(4)L(3)](2)(-) (L = Cl(-) (8), EtS(-) (9), p-MeC(6)H(4)S(-), p-MeC(6)H(4)O(-)). A new procedure for the preparation of molybdenum single cubanes is introduced by the reaction of recently reported [(Tp)MoS(S(4))](-) with FeCl(2)/NaSEt to afford [(Tp)MoFe(3)S(4)Cl(3)](-) (1, 75% yield). This procedure is more efficient that the existing multistep synthesis of single cubanes, which generally affords clusters of mirror symmetry. Also prepared were [(Tp)MoFe(3)S(4)L(3)](-) (L = EtS(-) (2), p-MeC(6)H(4)S(-)). Reduction of 1 with borohydride gives [(Tp)MoFe(3)S(4)Cl(3)](2-) (5, 67%). Owing to the nature of the heterometal ligand, all clusters have idealized trigonal symmetry, reflected in their (1)H NMR spectra. Trigonal structures are demonstrated by crystallography of (Bu(4)N)[1,2], (Bu(4)N)(2)[5] x MeCN, and (Me(4)N)(2)[8,9]. The availability of 1 and 5 allows the first comparison of structures and (57)Fe isomer shifts of [MoFe(3)S(4)](3+,2+) in a constant ligand environment. Small increases in most bond distances indicate that an antibonding electron is added in the reduction of 1. Collective synthetic and electrochemical results from this and other studies demonstrate the existence of the series of oxidation states [VFe(3)S(4)](3+,2+,1+) and [MoFe(3)S(4)](4+,3+,2+) whose relative stabilities within a given series are strongly ligand dependent. Isomer shifts indicate that the reduction of 1 largely affects the Fe(3) subcluster and are consistent with the formal descriptions [MoFe(3+)(2)Fe(2+)S(4)](3+) (1) and [MoFe(3+)Fe(2+)(2)S(4)](2+) (5). Reaction of 1 with excess Li(2)S in acetonitrile affords the double cubane [[(Tp)MoFe(3)S(4)Cl(2)](2)(mu(2)(-)S)](2)(-), whose sulfide-bridged structure is supported by two sequential reductions separated by 290 mV, in analogy with

Discovery and analysis of care meanings, expressions, and practices of Iranian Immigrants in New South Wales, Australia was the focus of this ethnonursing qualitative research. The purpose of the study was to systematically discover, describe and analyse the values, beliefs, and practices of Iranian immigrants in New South Wales, Australia. The aim of the investigation was to discover transcultural nursing knowledge to guide nurses and health professionals to provide culturally congruent nursing and health care to Iranians. Leininger's theory of Culture Care Diversity and Universality (Leininger, 1991) was used as the conceptual framework for the study. It was predicted that care meanings and expressions of Iranian immigrants would be influenced by their worldview, social structure features, language, and cultural values rooted in their long ethnohistorical past and reflected in their lifeways in Australia. Using the ethnonursing qualitative research method, key and general informants were purposefully selected among Iranian immigrants residing in New South Wales. Three care themes supported by a number of universal and some diverse patterns were identified for Iranian immigrants. The three themes were: (1) Care meant family and kinship ties (hambastegie) as expressed in daily lifeways and interactions with family, friends, and community; (2) Care as expressed in carrying out traditional urban gender roles (role-zan-o-mard) (Azadie zan) as well as in fulfilling emerging new role responsibilities related to equality for female Iranian immigrants; and (3) Care as preservation of Iranian identity (inhamoni, hamonandi) as expressed in traditional cultural events and health care practices. Leininger's (1991) three modes of actions and decisions were used to develop appropriate and culturally meaningful nursing care actions and decisions which were in harmony with the cultural beliefs of Iranian immigrants.

Full Text Available This study intends to evaluate the impacts of implementing online marketing strategies on Iranian ecotourism industry. The study had eight hypotheses which were designed based on economic, sociological, and cultural aspects of Iranian ecotourism industry. The results indicate that the expansion of online marketing increased the number of foreign tourists who visited Iran’s natural tourist attractions, while it had no significant impact on the number of domestic tourists who visited these tourist attractions. The results also indicated that online marketing did not increase the amount of investment in Iranian ecotourism industry. Additionally, online ecotourism marketing did not have a significant influence on the total number of travels to Iran’s historical tourist attractions. Respondents believe implementing online marketing strategies in Iranian ecotourism industry helps Iran expand its cultural tourism in rural areas and it expands its hospitality industry; they also believe that online marketing helps to create more jobs in Iranian ecotourism industry and to improve working conditions in this industry.

Cosmic ray dosimetry measurements were carried out on board a Global Express business jet operated by TAG Aviation (UK) during a pole-to-pole flight sequence that took place in November 2008. One Hawk TEPC and two EPDN2s were flown, and the TEPC measurements compared to calculated values from the route dose codes AVIDOS, CARI 6M, EPCARD versions 3.2 and 3.34, QARM and SIEVERT (online version). The largest difference between measured and calculated doses for the total flight sequence was found to be 13%. Agreement between the readings of the TEPC and the EPDN2s (once a calibration factor from the CERN High Energy Reference Field had been applied) was reasonably good given the relatively large uncertainties associated with the EPDN2 measurements.

Complimenting Functions by Native English Speakers and Iranian EFL Learners: A Divergence or Convergence

Full Text Available The study of compliment speech act has been under investigation on many occasions in recent years. In this study, an attempt is made to explore appraisals performed by native English speakers and Iranian EFL learners to find out how these two groups diverge or converge from each other with regard to complimenting patterns and norms. The participants of the study were 60 advanced Iranian EFL learners who were speaking Persian as their first language and 60 native English speakers. Through a written Discourse Completion Task comprised of eight different scenarios, compliments were analyzed with regard to topics (performance, personality, possession, and skill, functions (explicit, implicit, and opt-out, gender differences and the common positive adjectives used by two groups of native and nonnative participants. The findings suggested that native English speakers praised individuals more implicitly in comparison with Iranian EFL learners and native speakers provided opt-outs more frequently than Iranian EFL learners did. The analysis of data by Chi-square showed that gender and macro functions are independent of each other among Iranian EFL learners’ compliments while for native speakers, gender played a significant role in the distribution of appraisals. Iranian EFL learners’ complimenting patterns converge more towards those of native English speakers. Moreover, both groups favored explicit compliments. However, Iranian EFL learners were more inclined to provide explicit compliments. It can be concluded that there were more similarities rather than differences between Iranian EFL learners and native English speakers regarding compliment speech act. The results of this study can benefit researchers, teachers, material developers, and EFL learners.

2017-08-01

Perturbative series of some quantities in quantum field theories, such as the pole mass of a quark, suffer from a kind of divergence called renormalon divergence. In this paper, the leading renormalon in the pole mass is investigated, and a map is introduced to suppress this renormalon. The inverse of the map is then used to generate the leading renormalon and obtain an expression to calculate its overall normalization. Finally, the overall normalization of the leading renormalon of the pole mass is calculated for several values of quark flavors.

JLC will provide a high luminosity of 2.0 x 10 33 cm -2 s -1 on the Z-pole. To realize the Z-pole running we need to add a transport line to bypass unnecessary part of the main linac. With this high luminosity, the third angle of the unitality triangle (sin 2φ 3 ) can be measured in B s (B s ) → pK s channel with 3σ sensitivity in 1 year when sin 2φ 3 = -0.5, Xs = 10, and the branching ratio of the channel is 2 x 10 -5 . Also sin 2 θw can be measured with accuracy of Δsin 2 θw/sin 2 θw = 0.1%. (J.P.N.)

Cernogora, Jacqueline

In France in 1968 many lively discussions and debates took place at several universities and laboratories in which official authority was questioned. Very often in such debates someone would stand up and ask the previous speaker: "Who are you to assert such a thing?" or "From where are you speaking?" Forty years later, to avoid such questions, I will say right away "from where" I am writing this text, which is by no means an exhaustive study of French-Cuban collaboration in physics at that time, but rather a personal recollection.

This study examined the relationship between three mental health constructs and perceived cultural attitudes toward homosexuality among lesbian, gay, and bisexual individuals. Specifically, differences in perceived cultural attitudes and depression, self-esteem, and perceived stress between 49 Iranians and 47 Americans were compared. It was hypothesized that (a) perceived cultural attitudes toward homosexuality would be more negative among Iranians than Americans; (b) perceived cultural attitudes would be related to depression, self-esteem, and perceived stress; and (c) that Iranian participants' scores on the depression, self-esteem, and perceived stress measures would reflect poorer mental health than that of their American counterparts. Results indicated more negative perceptions of cultural attitudes toward homosexuality among Iranians. Contrary to prediction, however, no difference was found in levels of depression, self-esteem, and perceived stress among American and Iranian participants. Findings are discussed in terms of cultural and familial differences with regard to sexual orientation disclosure.

Dickman, S. R.

1985-01-01

The dynamic pole tide is characterized in a self-consistent manner by means of introducing a single nondifferential matrix equation compatible with the Liouville equation, modelling the ocean as global and of uniform depth. The deviations of the theory from the realistic ocean, associated with the nonglobality of the latter, are also given consideration, with an inference that in realistic oceans long-period modes of resonances would be increasingly likely to exist. The analysis of the nature of the pole tide and its effects on the Chandler wobble indicate that departures of the pole tide from the equilibrium may indeed be minimal.

The presence of hair plays an important role in people's overall physical appearance and self-perception. As a result of increased life expectancy, the desire to look youthful plays a bigger role than ever.The use of medicinal plants is as old as mankind and the market will face many new products containing natural oils and herbs in coming years. In traditional Iranian medicine, many plants and herbal formulations are reported for hair growth as well as the improvement in hair quality. The aim of this article is to introduce effective medicinal plants in traditional Iranian medicine to prevent gray hair and advocate them as the new products. The present investigation is an overview study and has been codified by library search in the main sources of traditional Iranian medicine. In traditional Iranian medicine, three types of formulations are proposed to prevent gray hair, namely (i) treatment compounds, (ii) preventive compounds, and (iii) hair dyes to color gray hairs. Our search showed that the main parts of a plant that is used in the treatment and preventive compounds are seeds and fruits. These are primarily in the form of topical oil or oral compound (electuary). The majority of plant parts used in hair dyes is from the fruit and/or leaves. Natural products are highly popular and the use of plant extracts in formulations is on the rise. This is because synthetic based product may cause health hazards with several side effects. Considering the increased popularity of herbal drugs in hair care, it is worthwhile to conduct systemic investigation on the production and efficacy of these drugs. We trust that our investigation would encourage the use of traditional Iranian medicine in future hair care products.

Full Text Available Iran together with Afghanistan is the third largest producer and exporter of cashmere in the world, after China and Mongolia. This paper assesses the status of cashmere marketing of Iran in order to evaluate sustainability, and to identify some constraints limiting the productivity and compa-tibility. In August to December 2011 structured questionnaires and interviews were used to compile information regarding market chains cashmere industry of Iran. Information compiled revealed that nearly all the cashmere was marketed by direct buying in Iran. The principle centers for the gathering and rough sorting raw cashmere in Iran were Baft, Sirjan, Mashad, and Birjand. The principle cashmere-importing countries of Iranian cashmere were China, England, Belgium and Italy. The price for Iranian cashmere has showed large fluctuations in the last forty years: it increased from 25 dollars in 1972 to 110 dollars in 1988 and decreased to 65 dollars in 2006 and again increased to 110 dollars in 2012. Given the present status of production and marketing there seems to be substantial scope to improve the value addition of Iranian cashmere.

Full Text Available This study investigates the level of Narcissism among 185 Iranian auditors groups and narcissism has been used to describe people behavior in people groups. The present study uses a questionnaire to measure Narcissism and to examine the hypotheses of the paper analysis of variance and T-test are used. The results of testing hypotheses show that the level of narcissism was significantly different in auditors groups in private sector. However, in public sector, the difference between narcissistic personality in auditors’ groups is not significant. Results of the study also indicated that, in private sector, narcissistic personality in young generation of auditors was higher than audit old generation. These results confirm previous studies on narcissism indicating that narcissistic behavior was high among young generation. We suggest the Iranian association of certified public accountants (IACPA to review the ethical training needs for auditors. In addition, audit firms can provide a system to increase interaction among old generations of auditors with young generation of auditors.

A variable-mode stator consequent pole memory machine

Yang, Hui; Lyu, Shukang; Lin, Heyun; Zhu, Z. Q.

2018-05-01

In this paper, a variable-mode concept is proposed for the speed range extension of a stator-consequent-pole memory machine (SCPMM). An integrated permanent magnet (PM) and electrically excited control scheme is utilized to simplify the flux-weakening control instead of relatively complicated continuous PM magnetization control. Due to the nature of memory machine, the magnetization state of low coercive force (LCF) magnets can be easily changed by applying either a positive or negative current pulse. Therefore, the number of PM poles may be changed to satisfy the specific performance requirement under different speed ranges, i.e. the machine with all PM poles can offer high torque output while that with half PM poles provides wide constant power range. In addition, the SCPMM with non-magnetized PMs can be considered as a dual-three phase electrically excited reluctance machine, which can be fed by an open-winding based dual inverters that provide direct current (DC) bias excitation to further extend the speed range. The effectiveness of the proposed variable-mode operation for extending its operating region and improving the system reliability is verified by both finite element analysis (FEA) and experiments.

2018-03-01

Full Text Available The present study was conducted to identify the perceptions of the Iranian foreign language practitioners about Iran‟s foreign language education policy within a systemic functional linguistics approach. To this end, 8 Iranian male and female foreign language practitioners were interviewed and asked to talk about what they thought about Iran‟s foreign language policy. The findings obtained from analysing the process types and participants employed by the Iranian foreign language practitioners within a systemic functional linguistics approach point out that the FLEP document is heavily influenced by and draws on well entrenched ideological, historical, religious, economic, and political discourses. Further investigations within a systemic functional linguistics approach indicate that the Iranian teachers believed that while English is a tool for understanding cultural exchanges and transferring technological advances, achieving these goals through the teaching of English is sometimes problematic within an absolute Islamic framework. The findings obtained from a transitivity analysis for the Iranian foreign language practitioners by subjecting their responses to the questions on the interviews to a systemic functional linguistics approach are also indicative of the Iranian foreign language teachers‟ loyalty to the “the younger, the better” belief. Likewise, course content was a topic for controversy. Some of the practitioners believed that course content should be developed around a variety of topics. Whereas others asserted that the inclusion of different topics in the foreign language education policy document may increase the workload on the part of the teachers. Other issues such as culture, the Islamic ideology, and imperialism were identified as causes of different understandings among the Iranian foreign language practitioners as well.

Full Text Available Se realiza un análisis metodológico conceptual de la Psiquiatría como ciencia partiendo de los criterios de los psiquiatras cubanos, coincidiendo en que es una rama de las Ciencias Médicas, en la cual el objeto de estudio es la enfermedad mental o el proceso salud enfermedad mental y sus acciones es el diagnóstico, tratamiento, etiopatogenia, rehabilitación y prevención de las mismas, así como su estudio epidemiológico y que incluye el carácter social e interdisciplinario. A partir de la reorientación de la Psiquiatría hacia la comunidad se hace una reflexión del significado e implicaciones de la misma. Se argumenta como en Cuba se aplica el Modelo de la Atención Comunitaria de Salud Mental a través de los Centros comunitarios de Salud Mental que constituyen la piedra angular del modelo cubano de atención comunitaria, con los que constituye la Psiquiatría comunitaria el nuevo paradigma de la Psiquiatría cubana actual. Se reconoce que el fundamento filosófico que sustenta a la Psiquiatría cubana actual es la teoría Marxista LeninistaA conceptual and methodological analysis of Psychiatry as a science is made, taking the Cuban psychiatrists' criteria as a starting point, referring to it as a branch of the Medical Sciences, in which the object of study is the mental illness or the process health-mental illness, being its actions the diagnosis, treatment, ethiology and pathogenesis, rehabilitation and prevention, as well as its epidemiological study that is related to the social and interdisciplinary levels.

Written-Pole{sup TM} technology is a patented machine technology, which changes the magnetic polarity of the rotor field in a rotating machine, while the machine is operating. The number of poles is thereby changed, resulting in a constant frequency - variable speed machine. When operating as a motor, a Written-Pole machine has inherently low starting current and high operating efficiency. (orig.)

Tanaka, K; Narazaki, A; Hirao, K

2000-02-15

Second-harmonic generation, one of the second-order nonlinear optical properties of thermally and electrically poled WO>(3)-TeO>(2) glasses, has been examined. We poled glass samples with two thicknesses (0.60 and 0.86 mm) at various temperatures to explore the effects of external electric field strength and poling temperature on second-order nonlinearity. The dependence of second-harmonic intensity on the poling temperature is maximum at a specific poling temperature. A second-order nonlinear susceptibility of 2.1 pm/V was attained for the 0.60-mm-thick glass poled at 250 degrees C. This value is fairly large compared with those for poled silica and tellurite glasses reported thus far. We speculate that the large third-order nonlinear susceptibility of WO>(3)- TeO>(2) glasses gives rise to the large second-order nonlinearity by means of a X((2)) = 3X((3)) E(dc) process.

This report explores the participation of some afferent mechanisms in the immune response induced by the Cuban anti-meningococcal vaccine VA-MENGOC-BC. The induction of delayed-type hypersensitivity in nursing babies and lymphocyte proliferation after immunization is demonstrated. The presence of gamma interferon IFN-γ and interleukin-2 (IL-2) mRNAs but absence of IL-4, IL-5, and IL-10 mRNAs were observed in peripheral blood mononuclear cells from immunized subjects after in vitro challenge with outer membrane vesicles. In addition, some effector functions were also explored. The presence of opsonic activity was demonstrated in sera from vaccinees. The role of neutrophils as essential effector cells was shown. In conclusion, we have shown that, at least in the Cuban adult population, VA-MENGOC-BC induces mechanisms with a T-helper 1 pattern in the afferent and effector branches of the immune response.

OSBPL10, RXRA and lipid metabolism confer African-ancestry protection against dengue haemorrhagic fever in admixed Cubans.

Directory of Open Access Journals (Sweden)

Beatriz Sierra

2017-02-01

Full Text Available Ethnic groups can display differential genetic susceptibility to infectious diseases. The arthropod-born viral dengue disease is one such disease, with empirical and limited genetic evidence showing that African ancestry may be protective against the haemorrhagic phenotype. Global ancestry analysis based on high-throughput genotyping in admixed populations can be used to test this hypothesis, while admixture mapping can map candidate protective genes. A Cuban dengue fever cohort was genotyped using a 2.5 million SNP chip. Global ancestry was ascertained through ADMIXTURE and used in a fine-matched corrected association study, while local ancestry was inferred by the RFMix algorithm. The expression of candidate genes was evaluated by RT-PCR in a Cuban dengue patient cohort and gene set enrichment analysis was performed in a Thai dengue transcriptome. OSBPL10 and RXRA candidate genes were identified, with most significant SNPs placed in inferred weak enhancers, promoters and lncRNAs. OSBPL10 had significantly lower expression in Africans than Europeans, while for RXRA several SNPs may differentially regulate its transcription between Africans and Europeans. Their expression was confirmed to change through dengue disease progression in Cuban patients and to vary with disease severity in a Thai transcriptome dataset. These genes interact in the LXR/RXR activation pathway that integrates lipid metabolism and immune functions, being a key player in dengue virus entrance into cells, its replication therein and in cytokine production. Knockdown of OSBPL10 expression in THP-1 cells by two shRNAs followed by DENV2 infection tests led to a significant reduction in DENV replication, being a direct functional proof that the lower OSBPL10 expression profile in Africans protects this ancestry against dengue disease.

Recent technological developments in medicine, including modern radiology have promoted the impact of scientific researches on social life. The scientific outputs such as article and patents are products that show the scientists’ attempt to access these achievements. In the current study, we evaluate the current situation of Iranian scientists in the field of radiology and compare it with the selected countries in terms of scientific papers. For this purpose, we used scientometric tools to quantitatively assess the scientific papers in the field of radiology. Radiology papers were evaluated in the context of medical field audit using retrospective model. We used the related databases of biomedical sciences for extraction of articles related to radiology. In the next step, the situation of radiology scientific products of the country were determined with respect to the under study regional countries. Results of the current study showed a ratio of 0.19% for Iranian papers in PubMed database published in 2009. In addition, in 2009, Iranian papers constituted 0.29% of the Scopus scientific database. The proportion of Iranian papers in the understudy region was 7.6%. To diminish the gap between Iranian scientific radiology papers and other competitor countries in the region and achievement of document 2025 goals, multifold effort of the society of radiology is necessary

Discoveries of linguistic terms relating to care/caring can create better understanding of diversities in expression and experiences of care of different cultures. Such linguistic understandings and discovery of "meaning-in-context" can enhance communication toward unity in light of diversity. In order to gain an understanding of expression of care/caring for Iranian immigrants in New South Wales, Australia, linguistic terms in the Persian language as discovered are described. The study, conceptualised within Leininger's theory of Culture Care diversity and universality led to the discovery of 31 linguistic care terms in the Persian language, reflecting the emic view of care for Iranian Immigrants in multicultural Australia. Using Leininger's ethnonursing research method and in depth naturalistic interviews, five types of care were abstracted from recurrent patterning and saturation according to type and meaning of care were discovered and described. The five categories describe care as: action; (hamoyat, parastari), thoughts; (ba-fakr-ham-boodan), reflecting family ties; (hambastegie), care as being Iranian, reflecting Iranian identity; (inhamani, hamonandi). Finally, care as related to context and expressed in safety and peace; (amnieyat, aramash), describing Australia as a safe and peaceful place to live. This paper will attempt to share an Iranian immigrants' emic view of care.

Full Text Available In post-Soviet period Russia and Iran have experienced quite a few sharp turns in bilateral relations. Periods of active dialogue alternated with long pauses, signing of multibillion-dollar contracts was replaced by the prosecution of both parties in default of its obligations and commitments. Geopolitical interests in this case take precedence over economic ones. The article describes the role of the Iranian issue in Russian-US relations, both within the Gore-Chernomyrdin Commission and concerning Iranian nuclear program. The question of the legal status of the Caspian Sea also affects bilateral relations. However, there are a number of objective factors that bring together country. Among them is a need to combat ethnic separatism as well as shock economic reforms started almost simultaneously in Russia and Iran in the early 1990s and led to an increase in social tension. Both countries are interested in maintaining peace and stability in the former Soviet republics of Central Asia, Caucasus and Afghanistan. In July 2005, Iran received observer status at the Shanghai Cooperation Organization (SCO. With the return to the post of Russian president Vladimir Putin in 2012, there has been improvement in Russian-Iranian relations. There has been a number of positive trends in trade and economic relations, implementation of joint economic projects.

Surrogacy is a popular form of assisted reproductive technology of which only gestational form is approved by most of the religious scholars in Iran. Little evidence exists about the Iranian infertile women's viewpoint regarding gestational surrogacy. To assess the viewpoint of Iranian infertile women toward gestational surrogacy. This descriptive study was conducted at the infertility clinic of Tabriz University of Medical Sciences, Iran. The study sample consisted of 238 infertile women who were selected using the eligible sampling method. Data were collected by using a researcher developed questionnaire that included 25 items based on a five-point Likert scale. Data analysis was conducted by SPSS statistical software using descriptive statistics. Viewpoint of 214 women (89.9%) was positive. 36 (15.1%) women considered gestational surrogacy against their religious beliefs; 170 women (71.4%) did not assume the commissioning couple as owners of the baby; 160 women (67.2%) said that children who were born through surrogacy would better not know about it; and 174 women (73.1%) believed that children born through surrogacy will face mental problems. Iranian infertile women have positive viewpoint regarding the surrogacy. However, to increase the acceptability of surrogacy among infertile women, further efforts are needed.

Herbal distillates have been used as beverages, for flavoring, or as phytomedicines in many countries for a long time. Recently, the occurrence of blindness after drinking herbal distillates has created concerns in Iran. The aim of this study was to determine the concentrations of methanol in herbal distillates produced in Iran. Eighty-four most commonly used herbal distillates purchased from herbal distillate factories were analyzed for methanol contents by gas chromatography and flame ionization detection, with ethanol as internal standard. In 15 herbal distillates, the methanol concentration was below the limit of quantitation. The methanol concentrations in all samples ranged from 43 to 277 mg/L. Forty-five samples contained methanol in excess of the Iranian standard. The maximum concentration was found in an herbal distillate of Mentha piperita (factory E) (277±12), and the minimum in a distillate of Carum carvi (factory B) (42.6 ± 0.5). Since the 45 Iranian herbal distillates containing methanol levels were beyond the legal limits according to the Iranian standard, it seems necessary to monitor the amount of methanol and give a warning to watch out for the latent risk problem of methanol uptake, and establish a definitive relationship between the degree of intoxication observed and the accumulation of methanol in the blood.

Revolutionizing Cuban Psychiatry: The Freud Wars, 1955-1970.

Science.gov (United States)

Lambe, Jennifer Lynn

2017-01-01

This article traces the battle over Freud within Cuban psychiatry from its pre-1959 origins through the "disappearance" of Freud by the early 1970s. It devotes particular attention to the visit of two Soviet psychiatrists to Cuba in the early 1960s as part of a broader campaign to promote Pavlov. The decade-long controversy over Freud responded to both theoretical and political concerns. If for some Freud represented political conservatism and theoretical mystification, Pavlov held out the promise of a dialectical materialist future. Meanwhile, other psychiatrists clung to psychodynamic perspectives, or at least the possibility of heterogeneity. The Freudians would end up on the losing side of this battle, with many departing Cuba over the course of the 1960s. But banishing Freud did not necessarily make for stalwart Pavlovians-or vanguard revolutionaries. Psychiatry would find itself relegated to a handmaiden position in the work of revolutionary mental engineering, with the government itself occupying the vanguard.

Time domain oscillating poles: Stability redefined in Memristor based Wien-oscillators

KAUST Repository

Talukdar, Abdul Hafiz Ibne

2012-07-28

Traditionally, the necessary and sufficient condition for any system to be oscillating is that its poles are located on the imaginary (jω) axis. In this paper, for the first time, we have shown that systems can oscillate with time-domain oscillating poles. The idea is verified using a Memristor based Wien oscillator. Sustained oscillations are observed without having the poles of the system fixed on the imaginary axis and the oscillating behavior of the system poles is reported. The oscillating resistance and triangular shape of FFT are also demonstrated with mathematical reasoning and simulation results to support the unusual and surprising characteristics. © 2009 IEEE.

Iranian Political Strategy: Ideology or Pragmatism

International Nuclear Information System (INIS)

Saada, Julien

2008-01-01

Iranian political strategy wants to be presented as a political break, with a Pan-Islamic vocation. Brought about by Ayatollah Khomeyni, this political philosophy has produced the intended effects, as seen with the return of more moderate policies. Khomeyni's death confronted the Islamic Republic with a choice: Hachemi Rasfandjani put Iran back into the international scene by conciliating pragmatism with ideological values. In 2005, M. Ahmadinejad came to power. His declarations concerning the Hebrew State and his position on nuclear weapons pose the question as to whether or not Iran is reverting to an export policy of revolution. It is important to place these elements in the historical context of the Islamic Republic so as to see if Iranian foreign policy is again taking an ideological turn or if it is continuing down the lane of pragmatism

Converting point-wise nuclear cross sections to pole representation using regularized vector fitting

Peng, Xingjie; Ducru, Pablo; Liu, Shichang; Forget, Benoit; Liang, Jingang; Smith, Kord

2018-03-01

Direct Doppler broadening of nuclear cross sections in Monte Carlo codes has been widely sought for coupled reactor simulations. One recent approach proposed analytical broadening using a pole representation of the commonly used resonance models and the introduction of a local windowing scheme to improve performance (Hwang, 1987; Forget et al., 2014; Josey et al., 2015, 2016). This pole representation has been achieved in the past by converting resonance parameters in the evaluation nuclear data library into poles and residues. However, cross sections of some isotopes are only provided as point-wise data in ENDF/B-VII.1 library. To convert these isotopes to pole representation, a recent approach has been proposed using the relaxed vector fitting (RVF) algorithm (Gustavsen and Semlyen, 1999; Gustavsen, 2006; Liu et al., 2018). This approach however needs to specify ahead of time the number of poles. This article addresses this issue by adding a poles and residues filtering step to the RVF procedure. This regularized VF (ReV-Fit) algorithm is shown to efficiently converge the poles close to the physical ones, eliminating most of the superfluous poles, and thus enabling the conversion of point-wise nuclear cross sections.

Little is known about the features of Iranian nursing journals, specifically the subject areas used in articles, study designs, sampling methods, international collaboration of Iranian nursing scholars, specialty and academic rank of authors, and the most frequently contributing academic institutions in articles. The aim of this study was to analyze the content of the articles published in Iranian scientific nursing journals. Quantitative content analysis was implemented to study Iranian nursing journals, which were approved by the commission for accreditation and improvement of Iranian medical journals in 2011. Thus, 763 articles from six journals, published from 2009 through 2011, were investigated. Data were extracted from the abstracts and when necessary, from the full-text of articles by visiting the websites of these journals. Descriptive statistics were used to analyze the data. The main subjects of published articles in Iranian scientific nursing journals were consecutively renal dialysis (n = 21), intensive care unit (n = 16), nursing education (n = 15), patient satisfaction (n = 13), quality of life (n = 12), health education (n = 11), patient education (n = 11), pain (n = 10), and education (n = 9). The majority of authors had nursing and midwifery specialty (52.59%) followed by epidemiology/biostatistics specialty (7.72%). Isfahan, Tehran, Shahid Beheshti, Iran, Baqiyatallah, and Urmia universities of medical sciences had consecutively the largest number of publications in the studied journals. Only three papers (0.39%) were published by the international collaboration. Iranian nursing journals should publish special issues in the neglected subject areas. These journals should encourage authors to publish research evidence with higher quality.

2013-06-01

Use of extracorporeal lithotripsy is declining in North America and many European countries despite international guidelines advocating it as a first-line therapy. Traditionally, lithotripsy is thought to have poor efficacy at treating lower pole renal stones. We evaluated the success rates of lithotripsy for lower pole renal stones in our unit. 50 patients with lower pole kidney stones ≤15 mm treated between 3/5/11 and 19/4/12 were included in the study. Patients received lithotripsy on a fixed-site Storz Modulith SLX F2 lithotripter according to a standard protocol. Clinical success was defined as stone-free status or asymptomatic clinically insignificant residual fragments (CIRFs) ≤3 mm at radiological follow-up. The mean stone size was 7.8 mm. The majority of stones (66 %) were between 5 and 10 mm. 28 % of stones were between 10 and 15 mm. For solitary lower pole stones complete stone clearance was achieved in 63 %. Total stone clearance including those with CIRFs was achieved in 81 % of patients. As expected, for those with multiple lower pole stones the success rates were lower: complete clearance was observed in 39 % and combined clearance including those with CIRFs was 56 %. Overall, complete stone clearance was observed in 54 % of patients and clearance with CIRFs was achieved in 72 % of patients. Success rate could not be attributed to age, stone size or gender. Our outcome data for the treatment of lower pole renal stones (≤15 mm) compare favourably with the literature. With this level of stone clearance, a non-invasive, outpatient-based treatment like lithotripsy should remain the first-line treatment option for lower pole stones. Ureteroscopy must prove that it is significantly better either in terms of clinical outcome or patient satisfaction to justify replacing lithotripsy.

Helen Safa has been a leading program builder and pioneer in research that examines the complex intersections of gender, race, class, and nation in Latin America and the Caribbean. Her comparative research culminated in her influential book, The Myth of the Male Breadwinner: Women and Industrialization in the Caribbean (1995), which examined gender, family, and employment across three Caribbean societies. Over several decades Safa has inspired scholarship throughout the Caribbean and the Americas and her work is exemplary of engaged anthropology in the region. Here I present work I conducted in Cuba that was guided, like my work in Peru, Nicaragua, and southern Mexico by the writings of Safa and others who saw the critical need to bring gender into meaningful discussion in the field of Latin American and Caribbean studies. In what follows, drawn from my broader research on tourism in four nations, I explore and reflect on the contemporary dynamics of sex and romance tourism in Cuba. I suggest that the allure of this domain of tourism may be enhanced by Cuba's global political identity, and that Cuban women participating in commodified and intimate exchanges reveal an ability to get along in a market economy that generally excludes them.

Studying the Identity of Iranian Classical Effective Literature and Contemporary Impressible Literature

Full Text Available After the advent of Islam in Iran, Persian Literature has always been considered as one of the major characteristics of Iranian culture and identity to the extent that some people believe whatever western has achieved in terms of literature – especially English literature – and honors to them originate from rich Persian literature. However, Persian literature has severely been influenced by works of western writers in contemporary era so that even modern Persian story and poem is divided based on western styles. Unfortunately, this situation – that a part of identity of Iranian culture has been drastically affected by alien culture – offends each educated Iranian. Today, a flashback to Iranian classical styles does not meet the need for a development created in literary works. However, it is necessary that tasteful and patriotic people create novel works in Iran’s contemporary literature against the decades-old literary identity of the west through adaptation of past-targeted literature and under the effect of conditions of today modern society in order to recover the lost identity of Iranian literature which other fields are considered as its subset. Therefore, this paper is going to present solutions for modeling the identity of Iranian literature for the next two decades in line with Islamization of universities in order to divide the pure academic literature into pure and applied sub-branches and develop academic literary activities. As a result, the international works would be established based on the columns of Persian literature whose kernel will not to be damaged in the rain and wind of alien cultures.

The present study investigated the relationship between sexual self-schema (i.e., beliefs about the sexual aspects of oneself), acculturation, and sex guilt, and it further examined the association between sex guilt and life satisfaction in Iranian American women. A total of 65 Iranian American women, with a mean age of 31.3 years (SD = 11.7), completed five self-administered questionnaires. Findings indicated a significant inverse correlation between sexual self-schema and sex guilt. More specifically, women who endorsed negative self-views regarding their sexual self reported higher levels sex guilt. Results revealed that acculturation was unrelated to sex guilt, when the effect of being Muslim or non-Muslim was controlled. Women with high sex guilt reported significantly lower levels of life satisfaction. Moreover, analyses for mediation effects supported sex guilt as a partially mediating variable between sexual self-schema and life satisfaction. Levels of sex guilt were higher among Muslim women when compared to women of other religious affiliations. Additionally, Muslim women appeared to be significantly less acculturated to Western ideals than other religious groups. The present findings suggest that mental health professionals who provide services to Iranian American women need to consider the negative effects of sex guilt, particularly among Muslim women.

Separable pole expansions in four-nucleon bound state calculations

We compare the utility of the Generalized Unitary Pole Expansion (GUPE) and the Energy-Dependent Pole Expansion (EDPE) for the three-body subsystem amplitudes in four-body state calculations for a variety of separable and local nucleon-nucleon interactions. It is found that, with the EDPE, the four-body binding energy is well reproduced with only two terms each for the (2+2)- and the (3+1)-subsystem, respectively, while the GUPE requires three terms for the (3+1)-channel and four terms for the (2+2)-channel. We thus conclude that pole dominance is of greater importance for the GUPE than for EDPE, which works equally well for both types of subsystems. It is found that both methods, in particular the EDPE, converge more rapidly with increasing repulsion in the two-body interaction, i.e. the more realistic the interaction becomes. Both expansions require similar computing times for a converged calculation and are about 15-20 times faster than the widely used Hilbert-Schmidt Expansion (HSE). The respective merits of the two pole expansions are discussed and compared with the HSE. (orig.)

What Perspectives for Crisis Resolution? Getting Out of the Iranian Crisis Peacefully

International Nuclear Information System (INIS)

Gere, Francois

2008-01-01

In February 2006, the International Atomic Energy Agency sent the Iranian case to the United Nations Security Council. However, Iran refused to stop its nuclear program. The international community has tried to elaborate a strategy to resolve the crisis, in order to avoid the 'bomb' or the 'bombardment.' France has moved closer to the Bush administration position, favoring diplomacy with sanctions. The situation remains extremely tense. Indeed, since February 2007, military tensions developed between American air and naval forces and the Iranian army in charge of coastal defense. Appeasement can only come through dialogue. But dialogue has not been initiated and Iranian diplomacy has only hardened over two years

2003-01-01

Good quality crystals of periodically poled lithium niobate can be generated directly during growth. However, the temperature gradients at the zone boundaries define the width of the regions where the polarity is reversed. Hence, the region influenced the domain transition may be a significant fraction of the overall poling period for material poled during growth. Evidence for the scale of this feature is reported both by chemical etching and by the less common method of ion beam luminescence and the 'domain wall' width approximately 1 mu m for these analyses. The influence of the reversal region may differ for alternative techniques but the relevance to device design for second harmonic generation is noted.

Full Text Available Islamic Revolution and the consequent Islamic state in Iran have revived Iranian-Islamic civilization’s discourse in a modern form which is rooted in both Iranian and Islamic ancient civilizations. Post-revolutionary Iran, as an obviously determinant country in this civilizational field, which has developed the civilization in the modern era, necessarily has to think and act civilizationally in order to resist western Humanist and Materialist affects. Academy is the place within which knowledge, as clearly one of the most important foundations of civilization-building, is produced. Civilization-building is the horizon toward which Iranian Universities should orient themselves. Academy is the canon of science, knowledge, and culture, and therefore plays an affective role in the formation, development and flourishing of a civilization; and it could be said that University is the foundation on which civilization is built. In other words, University in the modern era is not only the site of education and research, but also as an epistemological basis, participates in the process of culture and civilization-building; the matter which this study attempts to elaborate. Thus, we attempt to explain and define the necessary tools and indicators in the process.

Full Text Available Reviewing literature reveals that identifying generic structure of research articles (RAs in different fields of study, especially ESP, has received much attention. The major purpose behind such trends of research has been raising researchers' awareness of the common conventions in writing RAs. Along with this universal trend, a lot of genre studies have been done in Iranian context; however, it seems that ESP RAs have not been paid due attention yet. Hence this study aimed at investigating the generic structure of ESP RAs in international and Iranian journals. Applying Kanoksilapatham's (2007 model to the compiled corpus, it was found that contextualizing the study (Move 1 and consolidating results (Move 2 were the obligatory moves in Discussion section of ESP RAs across international and Iranian journals. Evaluation of the findings was a new step found in international Discussion sections but absent in Iranian ones. Related discussion of these findings prepares the researchers for publishing in international and Iranian ESP journals.

The aim of current study was to review breeding progress and update information on genetic strategies in Iranian buffaloes. Iranian buffalo is one of the vital domestic animals throughout north, north-west, south and south-west of Iran with measurable characteristics both in milk and meat production. The species plays an important role in rural economy of the country due to its unique characteristics such as resistance to diseases and parasites, having long productive lifespan and showing higher capability of consuming low-quality forage. In Iran, total production of milk and meat devoted to buffaloes are 293,000 and 24,700 tons, respectively. Selection activities and milk yield recording are carrying out by the central government through the Animal Breeding Centre of Iran. The main breeding activities of Iranian buffaloes included the estimation of genetic parameters and genetic trends for performance traits using different models and methods, estimation of economic values and selection criteria and analysis of population structure. Incorporating different aspects of dairy buffalo management together with improved housing, nutrition, breeding and milking, is known to produce significant improvements in buffalo production. Therefore, identifying genetic potential of Iranian buffaloes, selection of superior breeds, improving nutritional management and reproduction and developing the education and increasing the skills of practical breeders can be useful in order to enhance the performance and profitability of Iranian buffaloes.

We report in this study the frequency of Streptomyces strains to produce macrolide-lincosamide-streptogramin (MLS) antibiotics isolated from Cuban soils. The screening assay is based on the induction of MLS-resistance phenotype in a clinical isolated strain of Staphylococcus aureus S-18. Our results suggest that of 800 Streptomyces strains isolated from different soil samples, 6% were positives in the screening test used. The ferralitic red soil from Pinar del Río (north) provided the major percentage (3.6%) of MLS producing strains. The other soil samples tested belonging to Guira de Melena and Bauta in Havana, Matanzas City, Topes De Collantes (Villa Clara), and Soroa Mountains (Pinar del Rio) hill reached very low percentages.

Influence of the absorptive part of the complex potential on the S-Matrix poles

International Nuclear Information System (INIS)

Grama, C.; Grama, N.; Zamfirescu, I

2001-01-01

Although the polology of the S-matrix has been extensively studied, it occurred that some aspects remained disputable in the case of complex central potential V(r)=gV(r), g in C . These aspects are related to the origin of the observed narrow Σ-hypernuclear states that have been interpreted by Gal, Toker and Alexander as states which correspond to S-matrix poles situated in the second k-plane quadrant. From the analytical properties of the S-matrix for a real potential it results that there is no pole in the first and second k-plane quadrants, except for the imaginary k-axis. By switching on the absorption the S-matrix poles for real potential can evolve into the second quadrant of the k-plane. A critical study of the Σ-hypernuclear states needs the analysis of the motion of the S-matrix poles in the k-plane for variable complex coupling strength g. Recently contradictory opinions relative to the S-matrix poles trajectories in the complex k-plane for a complex square potential occurred. According to some authors the poles in the second quadrant can occur either from bound state poles moving anticlockwise, or from virtual state poles and capture resonant state poles moving clockwise as the absorption is switched on. Dabrowski argues that the statement made by Gal et al, Bonetti et al and Oset et al concerning the movement of the virtual poles with increasing absorptive potential is in general not correct. Dabrowski relates the direction in which the pole moves when the potential absorption increases to the direction in which the pole moves with increasing the real part of the potential, without clarifying this last question. For example, two poles moving in opposite directions along the imaginary k-axis are associated by Dabrowski to the same state. This is a wrong result, because one should associate a single pole to each quantum state. The aim of our work is to study the influence of the absorptive part of the potential on the S-matrix poles for the non

2012-01-01

Full Text Available BACKGROUND: This study aimed to compare Iranian elderly with the youth and middle aged population in terms of the prevalence of metabolic syndrome and its components in Iranian elderly METHODS: This cross-sectional study was conducted using the information from the third phase of Isfahan Healthy Heart Program. Male and female residents of Isfahan who aged over 19 years were selected by multistage cluster random sampling. A questionnaire including demographic characteristics, health status, medical history, medications used, as well as waist circumference, weight, height and systolic and diastolic blood pressures was completed for all participants. Fasting blood samples were obtained from all subjects and examined for fasting blood sugar and lipid profile. RESULTS: The prevalence of metabolic syndrome in individuals aged over 60 years was significantly higher than those under 60 (49.5% vs. 17.5%, respectively; P < 0.001. It was also more prevalent among elderly females than in males (59.2% vs. 39.8%, respectively; P < 0.005. Some anthropometric measures such as height, body mass index, abdominal circumference, waist-hip ratio, and waist to height ratio were significantly different in men and women below 60 years in comparison with those over 60 years (P < 0.05. Moreover, there were significant differences in most studied parameters between the elderly and non-elderly women (P < 0.001. Based on the findings of this study, the risk factors for cardiovascular diseases were significantly more prevalent in men and women over 60 years. T-test and Mann-Whitney were used for quantitative data and the square-chi test is performed for qualitative data.    CONCLUSION: This study showed that metabolic syndrome has a relatively high prevalence in Iranian elderly people (especially in women. Therefore, early diagnosis and management of the complication are recommended among this high-risk group. Keywords: Metabolic Syndrome, Elderly, Iran

Low equation, pion-nucleon scattering, and Castillejo-Dalitz-Dyson pole

International Nuclear Information System (INIS)

Nakano, K.; Nogami, Y.

1986-01-01

We examine the p-wave πN scattering at medium energies by means of the Low equation with a view to determining the form factor of the πN interaction. Solutions of the equation with and without a Castillejo-Dalitz-Dyson (CDD) pole are used. The solution with no CDD pole corresponds to the old Chew-Low model, whereas the one with a CDD pole corresponds to the quark version of the Chew-Low model. The πN interaction form factor is determined so that the Δ resonance is well reproduced. We find that the solution with a CDD pole leads to a softer form factor but is not as soft as those expected from the nucleon size in the quark model. Using the solutions and form factors thus determined, we also examine the pionic contributions to the nucleon magnetic moment and the nucleon mass

Background: Little is known about the features of Iranian nursing journals, specifically the subject areas used in articles, study designs, sampling methods, international collaboration of Iranian nursing scholars, specialty and academic rank of authors, and the most frequently contributing academic institutions in articles. Objectives: The aim of this study was to analyze the content of the articles published in Iranian scientific nursing journals. Materials and Methods: Quantitative content analysis was implemented to study Iranian nursing journals, which were approved by the commission for accreditation and improvement of Iranian medical journals in 2011. Thus, 763 articles from six journals, published from 2009 through 2011, were investigated. Data were extracted from the abstracts and when necessary, from the full-text of articles by visiting the websites of these journals. Descriptive statistics were used to analyze the data. Results: The main subjects of published articles in Iranian scientific nursing journals were consecutively renal dialysis (n = 21), intensive care unit (n = 16), nursing education (n = 15), patient satisfaction (n = 13), quality of life (n = 12), health education (n = 11), patient education (n = 11), pain (n = 10), and education (n = 9). The majority of authors had nursing and midwifery specialty (52.59%) followed by epidemiology/biostatistics specialty (7.72%). Isfahan, Tehran, Shahid Beheshti, Iran, Baqiyatallah, and Urmia universities of medical sciences had consecutively the largest number of publications in the studied journals. Only three papers (0.39%) were published by the international collaboration. Conclusions: Iranian nursing journals should publish special issues in the neglected subject areas. These journals should encourage authors to publish research evidence with higher quality. PMID:25741512

Moeini, Reihaneh; Gorji, Narjes

2016-05-01

Due to negligence, Persian (Iranian) traditional medicine has had a weak presence in the world of research for a long time. However, in recent years, a variety of activates by research and faculty centers have created awareness and a platform to introduce and promote Persian medicine to the world. The aim of this study is to present and analyze scientific achievements of Persian medicine in the world of research. Articles were collected from PubMed database using keywords such as "Persian medicine", "Persian traditional medicine", "Iranian medicine", and "Iranian traditional medicine". All data were classified based on the type of research (review, intervention, case reports, etc.), the field of study (neurology, cardiovascular, metabolic, historical studies, etc.), publication year, and journal type. A total of 501 articles were identified until the end of 2015, comprising of 222 reviews and 219 interventional (108 animal, 57 clinical and 54 cellular). Most studies were on neurology (20.1%), gastroenterology (14.5%), and cardiovascular diseases (10.4%). The publications in 2015 and 2014 had the highest hit rate with 139 and 132 articles, respectively, with 1:2 publication ratio between foreign and Iranian journals. The most published articles, both foreign and Iranian, were in "Evidence-Based Complementary and Alternative Medicine" and "Iranian Red Crescent Medicine" journals. The contribution of foreign authors was 5%. The primary focus of the articles was on "Basic concepts of Persian medicine", "Healthy lifestyle according to Persian medicine", and "Historical aspects", by 3.1%, 2.9%, and 6.7%, respectively. During the last 2 years, the number of articles published in Persian (Iranian) medicine, particularly clinical studies had significant growth in comparison with the years before. The tendency of foreign researchers to use the keywords "Iranian" or "Persian" medicine is notable. This research was only based on the designated keyword and other keywords were

Existing research rarely considers important ethnic subgroup variations in violent behaviors among Latino youth. Thus, their risk for severe violent behaviors is not well understood in light of the immense ethnic and generational diversity of the Latino population in the United States. Grounded in social control theory and cultural analyses of familism, we examine differences in the risk for severe youth violence, as well its associations with family cohesion, parental engagement, adolescent autonomy, household composition, and immigrant generation among Mexican (n = 1,594), Puerto Rican (n = 586), Cuban (n = 488), and non-Latino Black (n = 4,053), and White (n = 9,921) adolescents with data from the National Longitudinal Study of Adolescent Health. Results indicate a gradient of risk; White youth had the lowest risk for severe violence and Puerto Rican youth had the highest risk compared to all other racial/ethnic subgroups. Within-group analysis indicates that family factors are not universally protective or risk-inducing. While family cohesion decreased the risk of severe violence among all groups, parental engagement was associated with increased risk among Blacks and Whites, and adolescent autonomy was associated with increased risk among Puerto Ricans and Cubans. In addition, Cuban and White adolescents who lived in single parent households or who did not live with their parents, had higher risk for severe violent behaviors than their counterparts who lived in two parent households. Among Latinos, the association of immigrant generation was in opposite directions among Mexicans and Cubans. We conclude that family and immigration factors differentially influence risk for violence among Latino subgroups and highlight the significance of examining subgroup differences and developing intervention strategies that are tailored to the needs of each ethnic subgroup.

Na, Man Gyun; No, Hee Cheon

1992-01-01

An adaptive observer is designed that both parameters and state variables of the steam generator are estimated simultaneously. A pole assignment controller is derived on the basis of the adaptive observer. The characteristics of the overall closed-loop control system can be expressed in terms of its poles, assigned poles. The troublesome tuning procedure of the P-I controller is reduced to the determination of the desired poles only. The proposed algorithm is compared with the conventional P-I controller through numerical simulation. Also, the adaptive pole assignment controller is studied experimentally by implementing it to the mock-up of the nuclear steam generator. The adaptive pole assignment controller shows better responses than the P-l controller does. (Author)

Field analysis and enhancement of multi-pole magnetic components fabricated on printed circuit board

Chiu, K.-C.; Chen, C.-S.

2007-01-01

A multi-pole magnetic component magnetized with a fine magnetic pole pitch of less than 1 mm is very difficult to achieve by using traditional methods. Moreover, it requires a precise mechanical process and a complicated magnetization system. Different fine magnetic pole pitches of 300, 350 and 400 μm have been accomplished on 9-pole magnetic components through the printed circuit board (PCB) manufacturing technology. Additionally, another fine magnetic pole pitch of 500 μm was also fabricated on a dual-layered (DL) wire circuit structure to investigate the field enhancement. After measurements, a gain factor of 1.37 was obtained in the field strength. The field variations among different magnetic pole pitches were analyzed in this paper

2014-04-01

Full Text Available Introduction: Constipation is one of the most common pediatric disorders.In many cases, there is no anatomic endocrineor metabolic cause in explanation of chronic constipation.More than 85% of them called functional or idiopathic.Constipation is one of the serious disease in Iranian Traditional Medicine. Besides the problem it causes, chronic constipation can be the origin of many disease. That is why, ithas been called Mother of disease.The purpose of this study is to investigate the Constipation in children and the role of other organs such as the liver by view of Iranian Traditional Medicine   Materials and Method: This study is a review through Iranian traditional medicine references. At first, all the main available traditional books were reviewed. All the data about therapies of vaginal discharge in ITM were collected then classified.   Results: In traditional medicine different reasons have been mentioned for constipation especially for childrenwhich most of them are similar to etiology in Modern Medicine.Constipation due to liver disorder is one of the causes of constipation.In Iranian Traditional medicine` viewpoint, one of the mechanism for excretion is existence of secreted bile in intestine.If by any reason,measure or quality of its which secreted in intestine through bile changes or if intestinal mucous secretion becomes barrier for absorbing the food,it will caused disorder in excretion and finally will lead to constipation.Well known Iranian Traditional Medicine scientists, has mentioned all reasons for liver disorders and changing quality& quantity of secreted bile .he has mentioned the solutions as well.   Conclusion: It is hoped that by paying attention to constipation and with advanced clinical research we will be able to explain idiopathic constipation and prepare new ways of treatments for constipation. New researches have approved the effectiveness of these foods and drugs for treating the constipation.   Keywords

Iranian gas will be an issue

International Nuclear Information System (INIS)

Slovak, K.

2008-01-01

In this paper an interview with director of the Nabucco project, Reinhard Mitchek is published. There is extract from this interview: Iranian gas is a politically sensitive topic Europe cannot avoid I believe that it will become a topic in Europe in the medium to long term. Shouldn't Europe declare that it needs Iranian gas? Otherwise Russia or China may take over. I do not want to advise the European Commission via the media. Iranian gas would bring the Nabucco project closer to reality. A common European Union (EU) foreign policy and common foreign energy policy in particular will be of major importance. We of course need competition in the EU gas sector. But that is a business topic. The political issue is the competitiveness of Europe as an entity competing for energy sources with other regions. The European Union keeps repeating that the Nabucco project has high priority. But what steps has it undertaken to support it? The Commissioner for Energy, Andris Piebalgs, and the Commissioner for External Relations and European Neighbourhood Policy, Benita Ferrero-Waldner, visited Central Asia and supported the export of gas to Europe. That is exactly what Russia does and with more success. We will see. Naturally - these countries have a history of relationships with Russia. Turkmenistan and Kazakhstan have been exporting gas to Russia. But in the meantime these countries also want to extend their export portfolio. We think that through the Trans-Caspian pipeline and the existing gas pipeline connecting Azerbaijan with Turkey, gas from Azerbaijan and Turkmenistan will also get to Nabucco. (authors)

Consumer motivations toward buying local rice: The case of northern Iranian consumers.

This research had two purposes. The first aim was to identify Iranian and Non-Iranian rice consumers based on demographic characteristics and examine difference of these features with buying behaviors. The second purpose of study was to investigate consumer's motivation to buy local rice in Iran. The sample were 1500 people (men and women). The data was collected by using questionnaire based on a face-to-face survey. Chi-square, confirmatory factor analysis, and multiple linear regression were applied to assess collected data by a questionnaire survey. Regarding Iranian local rice buyers, 884 people buy local rice. Chi-square test showed that there is a significant difference between gender, having children, and marital status in buying local rice. Habitual Iranian local rice buyers include: female (51%), people who are more than 45 years old (51%), people with children (63%), people who are living urban (61%), married people (48%) and individuals that their monthly income is between 321.5 and 625 Dollars (53%). Regarding non-Iranian rice buyers, 616 people buy it. Also there is a significant difference between gender, location, marital status, and income in buying local rice. For considering consumers motivation toward buying local rice the econometrical model is used. Model had three aspects including; quality aspects (taste, good appearance), economic aspects (price, convenience, consumer's ethnocentrism), and safety aspects (health, not using pesticides and environment protection) and seven subset. The results of analysis indicated that quality aspects, economic aspects and safety aspects have positive effects on buying Iranian local rice. Also, indicative variables including; taste, good appearance, price, convenience, consumer's ethnocentrism, health, not using pesticides and environment have significant effects on buying it.

The self-consistent dynamic pole tide in non-global oceans

Science.gov (United States)

Dickman, S. R.

1988-01-01

The dynamic pole tide is determined by solving Laplace tide equations which take into account the presence of continents in oceans, oceanic self-gravitation and loading, and mantle elasticity. Dynamical effects are found to be only mild. It is shown that the dynamical pole tide contributes about one day more to the Chandler period than a static pole tide would, and dissipates wobble energy at a very weak rate. It is noted that, depending on the wobble period predicted for an oceanless elastic earth, mantle anelasticity at low frequencies may nevertheless contribute negligibly to the Chandler period.

[Mn4O4{O2P(OtBu)2}6] (1), an Mn4O4 cubane complex combining the structural inspiration of the photosystem II oxygen-evolving complex with thermolytic precursor ligands, was synthesized and fully characterized. Core oxygen atoms within complex 1 are transferred upon reaction with an oxygen-atom acceptor (PEt3), to give the butterfly complex [Mn4O2{O2P(OtBu)2}6(OPEt3)2]. The cubane structure is restored by reaction of the latter complex with the O-atom donor PhIO. Complex 1 was investigated as a precursor to inorganic Mn metaphosphate/pyrophosphate materials, which were studied by X-ray absorption spectroscopy to determine the fate of the Mn4O4 unit. Under the conditions employed, thermolyses of 1 result in reduction of the manganese to Mn(II) species. Finally, the related butterfly complex [Mn4O2{O2P(pin)}6(bpy)2] (pin = pinacolate) is described. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Full Text Available Post 9/11 the United States of America concerns the reconstruction of already demonized identities of Arabs and Middle-eastern cultures. Postcolonial works reside in their rendering a tragic or serious image of Middle Easterners to bring the Western (American audience into sympathizing with the Middle Eastern ethnicities. Could it be the case that a fundamentally humorous (not derogatory depiction might contribute to easing such cultural tensions? Firoozeh Jazayeri Dumas’ works stand out as critically acclaimed and successful works familiarizing the American audience with the more humane, likeable, sweet and funny aspects of the Iranians and Iranian culture, and the hardships of being an Iranian immigrant and becoming a hybrid individual. This article explores the already-hybridized self and psyche of Firoozeh as an Iranian American. She writes about her mother land and her residence country and comparing the way she has written about them can help readers understand how one can make peace between different parts of her identity.

Sun's pole-equator flux differences

Energy Technology Data Exchange (ETDEWEB)

Belvedere, G [Istituto di Astronomia dell' Universita di Catania, Italy; Paterno, L [Osservatorio Astrofisico di Catania, Italy

The possibility that large flux differences between the poles and the equator at the bottom of the solar convective zone are compatible with the small differences observed at the surface is studied. The consequences of increasing the depth of the convective zone due to overshooting are explored. A Boussinesq model is used for the convective zone and it is assumed that the interaction of the global convection with rotation is modelled through a convective flux coefficient whose perturbed part is proportional to the local Taylor number. The numerical integration of the equations of motion and energy shows that coexistence between large pole-equator flux differences at the bottom and small ones at the surface is possible if the solar convective zone extends to a depth of 0.4 R(Sun). The angular velocity distribution inside the convective zone is in agreement with the ..cap alpha omega..-dynamo theories of the solar cycle.

Full Text Available The paper analyzes the situation of clusters in Romania and their areas of activity and innovation in entrepreneurship Romanian state. It is made also a territorial distribution of clusters on the eight regions. The findings lead to the conclusion that there are some clusters that have the vocation to become poles of competitiveness in areas such as renewable energy, automotive, electronics, health, biotechnology, mechatronics or ICT (Information and Communication Technology which represent the resources for future of the Romanian economy. Regarding the degree of innovation of Romanian Small and Medium Enterprises (SMEs, the level is relatively modest, 30.8% of all enterprises being innovative. If we were to answer the question the title suggests, we would say "yes" to both since the innovative cluster as well as the competitiveness pole promotes par excellence, innovation through study, research and stimulation of creativity. And this is more than enough to support economic growth of Romania and maintain the competitiveness worldwide.

Purpose Recent studies have shown that 7-12% of endometrial cancers (ECs) are ultramutated due to somatic mutation in the proofreading exonuclease domain of the DNA replicase POLE. Interestingly, these tumors have an excellent prognosis. In view of the emerging data linking mutation burden, immune response and clinical outcome in cancer, we investigated whether POLE-mutant ECs showed evidence of increased immunogenicity. Experimental design We examined immune infiltration and activation according to tumor POLE proofreading mutation in a molecularly defined EC cohort including 47 POLE-mutant tumors. We sought to confirm our results by analysis of RNAseq data from the TCGA EC series and used the same series to examine whether differences in immune infiltration could be explained by an enrichment of immunogenic neoepitopes in POLE-mutant ECs. Results Compared to other ECs, POLE-mutants displayed an enhanced cytotoxic T cell response, evidenced by increased numbers of CD8+ tumor infiltrating lymphocytes and CD8A expression, enrichment for a tumor-infiltrating T cell gene signature, and strong upregulation of the T cell cytotoxic differentiation and effector markers T-bet, Eomes, IFNG, PRF and granzyme B. This was accompanied by upregulation of T cell exhaustion markers, consistent with chronic antigen exposure. In-silico analysis confirmed that POLE-mutant cancers are predicted to display more antigenic neo-epitopes than other ECs, providing a potential explanation for our findings. Conclusions Ultramutated POLE proofreading-mutant ECs are characterized by a robust intratumoral T cell response, which correlates with, and may be caused by an enrichment of antigenic neo-peptides. Our study provides a plausible mechanism for the excellent prognosis of these cancers. PMID:25878334

The creation of a specialized network of large, wide-angle telescopes for distributed observations of near-Earth space using a Russian-Cuban Observatory is considered. An extremely important goal of routine monitoring of near-Earth and near-Sun space is warding off threats with both natural and technogenic origins. Natural threats are associated with asteroids or comets, and technogenic threats with man-made debris in near-Earth space. A modern network of ground-based optical instruments designed to ward off such threats must: (a) have a global and, if possible, uniform geographic distribution, (b) be suitable for wide-angle, high-accuracy precision survey observations, and (c) be created and operated within a single network-oriented framework. Experience at the Institute of Astronomy on the development of one-meter-class wide-angle telescopes and elements of a super-wide-angle telescope cluster is applied to determine preferences for the composition of each node of such a network. The efficiency of distributed observations in attaining maximally accurate predictions of the motions of potentially dangerous celestial bodies as they approach the Earth and in observations of space debris and man-made satellites is estimated. The first estimates of astroclimatic conditions at the proposed site of the future Russian-Cuban Observatory in the mountains of the Sierra del Rosario Biosphere Reserve are obtained. Special attention is given to the possible use of the network to carry out a wide range of astrophysical studies, including optical support for the localization of gravitational waves and other transient events.

The familiar axisymmetric zones and belts that characterize Jupiter’s weather system at lower latitudes give way to pervasive cyclonic activity at higher latitudes. Two-dimensional turbulence in combination with the Coriolis β-effect (that is, the large meridionally varying Coriolis force on the giant planets of the Solar System) produces alternating zonal flows. The zonal flows weaken with rising latitude so that a transition between equatorial jets and polar turbulence on Jupiter can occur. Simulations with shallow-water models of giant planets support this transition by producing both alternating flows near the equator and circumpolar cyclones near the poles. Jovian polar regions are not visible from Earth owing to Jupiter’s low axial tilt, and were poorly characterized by previous missions because the trajectories of these missions did not venture far from Jupiter’s equatorial plane. Here we report that visible and infrared images obtained from above each pole by the Juno spacecraft during its first five orbits reveal persistent polygonal patterns of large cyclones. In the north, eight circumpolar cyclones are observed about a single polar cyclone; in the south, one polar cyclone is encircled by five circumpolar cyclones. Cyclonic circulation is established via time-lapse imagery obtained over intervals ranging from 20 minutes to 4 hours. Although migration of cyclones towards the pole might be expected as a consequence of the Coriolis β-effect, by which cyclonic vortices naturally drift towards the rotational pole, the configuration of the cyclones is without precedent on other planets (including Saturn’s polar hexagonal features). The manner in which the cyclones persist without merging and the process by which they evolve to their current configuration are unknown.

Stabilization of Reduced Molybdenum-Iron-Sulfur Single and Double Cubane Clusters by Cyanide Ligation

Recent work has shown that cyanide ligation increases the redox potentials of Fe4S4 clusters, enabling the isolation of [Fe4S4(CN)4]4−, the first synthetic Fe4S4 cluster obtained in the all-ferrous oxidation state (Scott, T. A.; Berlinguette, C. P.; Holm, R. H.; Zhou, H.-C., Proc. Natl. Acad. Sci. USA 2005, 102, 9741). The generality of reduced cluster stabilization has been examined with MoFe3S4 clusters. Reaction of single cubane [(Tp)MoFe3S4(PEt3)3]1+ and edge-bridged double cubane [(Tp)2Mo2Fe6S8(PEt3)4] with cyanide in acetonitrile affords [(Tp)MoFe3S4(CN)3]2− (2) and [(Tp)2Mo2Fe6S8(CN)4]4− (5), respectively. Reduction of 2 with KC14H10 yields [(Tp)MoFe3S4(CN)3]3− (3). Clusters were isolated in ca. 70–90% yields as Et4N+ or Bu4N+ salts; Clusters 3 and 5 contain all-ferrous cores; 3 is the first [MoFe3S4]1+ cluster isolated in substance. The structures of 2 and 3 are very similar; the volume of the reduced cluster core is slightly larger (2.5%), a usual effect upon reduction of cubane-type Fe4S4 and MFe3S4 clusters. Redox potentials and 57Fe isomer shifts of [(Tp)MoFe3S4L3]2−,3 and [(Tp)2Mo2Fe6S8L4]4−,3− clusters with L = CN, PhS, halide, and PEt3 are compared. Clusters with π-donor ligands (L = halide, PhS) exhibit larger isomer shifts and lower (more negative) redox potentials while π-acceptor ligands (L = CN, PEt3) induce smaller isomer shifts and higher (less negative) redox potentials. When potentials of 3/2 and [(Tp)MoFe3S4(SPh)3]3−/2− are compared, cyanide stabilizes 3 by 270 mV vs. the reduced thiolate cluster, commensurate with the 310 mV stabilization of [Fe4S4(CN)4]4− vs. [Fe4S4(SPh)4]4− where four ligands differ. These results demonstrate the efficacy of cyanide stabilization of lower cluster oxidation states. (Tp = hydrotris(pyrazolyl)borate(1−)). PMID:17279830

To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = - 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

TERRITORIAL COHESION AND LOCAL DEVELOPMENT USING EUROPEAN STRUCTURAL AND COHESION FUNDS AT THE LEVEL OF GROWTH POLES – CASE STUDY GROWTH POLE BRASOV

2015-08-01

Full Text Available The growth poles were established in Romania in 2008 as centers for urban development in compliance with European and national policies and they include an urban nucleus and its rural surroundings.  According to the legal framework, for each of the growth poles an Integrated Development Plan should be adopted as basis for European Structural and Cohesion Funds investments. This is a new document in addition to local development plans/strategies of the local communities or counties and regional development plans. From another point of view, the growth poles are representing teritorial units which have to assure territorial cohesion for its urban and rural administrative units. Into this respect, there are different spatial planning documents which have to be followed by the territorial and administrative units, according to the Romanian legislation. Beyond these, there are rules and compulsory criterias for accessing European Structural and Cohesion funds the problems being faced by the associations established by local communities in order to manage the growth poles’s areas. Taking into account all these, we may say that growth poles are the crossing points for different policies translated into plans and operational programmes’s criterias for getting ESC Funds.

Don't trust equivalency presumptions when choosing distribution poles

Energy Technology Data Exchange (ETDEWEB)

Rollins, M.

2003-08-01

The variety of electric power distribution poles are described (wood, steel, prestressed concrete) in an effort to alert utilities that simple substitution of one type of pole for another based on presumed equivalency entails the risk that the replacement poles are unfit for the load conditions and do not comply with National Electrical Safety Code (NESC) requirements. A thorough evaluation of all design loads and the proper application of the appropriate overload and strength factors must take place prior to selecting the type of replacement to avoid misapplication of a product in situations for which it was not designed. Relevant provisions of NESC are described.

A survey of the current status of web-based databases indexing Iranian journals.

2009-05-01

The scientific output of Iran is increasing rapidly during the recent years. Unfortunately, most papers are published in journals which are not indexed by popular indexing systems and many of them are in Persian without English translation. This makes the results of Iranian scientific research unavailable to other researchers, including Iranians. The aim of this study was to evaluate the quality of current web-based databases indexing scientific articles published in Iran. We identified web-based databases which indexed scientific journals published in Iran using popular search engines. The sites were then subjected to a series of tests to evaluate their coverage, search capabilities, stability, accuracy of information, consistency, accessibility, ease of use, and other features. Results were compared with each other to identify strengths and shortcomings of each site. Five web sites were indentified. None had a complete coverage on scientific Iranian journals. The search capabilities were less than optimal in most sites. English translations of research titles, author names, keywords, and abstracts of Persian-language articles did not follow standards. Some sites did not cover abstracts. Numerous typing errors make searches ineffective and citation indexing unreliable. None of the currently available indexing sites are capable of presenting Iranian research to the international scientific community. The government should intervene by enforcing policies designed to facilitate indexing through a systematic approach. The policies should address Iranian journals, authors, and indexing sites. Iranian journals should be required to provide their indexing data, including references, electronically; authors should provide correct indexing information to journals; and indexing sites should improve their software to meet standards set by the government.

To evaluate discriminant validity, reliability, internal consistency, and dimensional structure of the World Health Organization Quality of Life-BREF (WHOQOL-BREF) in a heterogeneous Iranian population. A clustered randomized sample of 2,956 healthy with 2,936 unhealthy rural and urban inhabitants aged 30 and above from two dissimilar Iranian provinces during 2006 completed the Persian version of the WHOQOL-BREF. We performed descriptive and analytical analysis including t-student, correlation matrix, Cronbach's Alpha, and factor analysis with principal components method and Varimax rotation with SPSS.15. The mean age of the participants was 42.2 +/- 12.1 years and the mean years of education was 9.3 +/- 3.8. The Iranian version of the WHOQOL-BREF domain scores demonstrated good internal consistency, criterion validity, and discriminant validity. The physical health domain contributed most in overall quality of life, while the environment domain made the least contribution. Factor analysis provided evidence for construct validity for four-factor model of the instrument. The scores of all domains discriminated between healthy persons and the patients. The WHOQOL-BREF has adequate psychometric properties and is, therefore, an adequate measure for assessing quality of life at the domain level in an adult Iranian population.

Russians, Jews, and Poles: Russification and Antisemitism 1881-1914

Directory of Open Access Journals (Sweden)

Theodor R. Weeks

2012-07-01

Full Text Available Relations between Poles and Jews deteriorated significantly in the three decades leading up to World War I. Many reasons for this phenomenon can be given, for example: economic competition, a general atmosphere of acute nationalism, increased migration, perceived threats to traditional forms of life and religion. Exacerbating all of these factors, however, was the fact of Polish statelessness and the extreme sensitivity of Poles to perceived threats to their culture and nation. In particular within the Russian Empire, Poles perceived the very future of their nation at risk. In such circumstances the continued existence of Jewish cultural difference combined with the development of specifically Jewish forms of national awakening (e.g., the Bund and Zionism were understood by many in Polish society as ingratitude and collaboration with the Russian occupier

Full Text Available Engineers think that pole embrace size of a PM BLDC motor affects directly the efficiency and the torque. Dealing with theexperimental research, in the studywe have investigated the effects of narrowing rotor pole embrace step by step by changing sizes parametrically. By doing so, high efficiency and low cogging torque would have been obtained for a 20 W PM BLDC motor. In order to do this,pole arc to pole pitch ratio of magnets at the rotor poles has been changed parametrically (0.5 to 1 by genetic algorithm methodfirst. Then the electromagnetic field dispersions, output parameters of the motor, new rotor constructions have been obtained; and new pole embrace has been derived from the variation of pole arc to pole pitch ratio. We have also calculatedthe magnetic flux distribution, output power, torque, cogging torque and efficiency values analytically and the effects of new pole embrace to motor efficiency and torque have been simulated. The developed 18 slots, 6 poles, surface mounted inner runner configuration rotor machine is proposed as to be used insmall dentistry apparatus.

The multiplication of nuclear actors who do not have the same experience is making the system unstable. Will we again have to experience the Cold War stages, with a new Cuban crisis, this time explicitly nuclear?

Periodically poled silicon

Bulk centrosymmetric silicon lacks second-order optical nonlinearity χ(2) - a foundational component of nonlinear optics. Here, we propose a new class of photonic device which enables χ(2) as well as quasi-phase matching based on periodic stress fields in silicon - periodically-poled silicon (PePSi). This concept adds the periodic poling capability to silicon photonics, and allows the excellent crystal quality and advanced manufacturing capabilities of silicon to be harnessed for devices based on χ(2)) effects. The concept can also be simply achieved by having periodic arrangement of stressed thin films along a silicon waveguide. As an example of the utility, we present simulations showing that mid-wave infrared radiation can be efficiently generated through difference frequency generation from near-infrared with a conversion efficiency of 50% based on χ(2) values measurements for strained silicon reported in the literature [Jacobson et al. Nature 441, 199 (2006)]. The use of PePSi for frequency conversion can also be extended to terahertz generation. With integrated piezoelectric material, dynamically control of χ(2)nonlinearity in PePSi waveguide may also be achieved. The successful realization of PePSi based devices depends on the strength of the stress induced χ(2) in silicon. Presently, there exists a significant discrepancy in the literature between the theoretical and experimentally measured values. We present a simple theoretical model that produces result consistent with prior theoretical works and use this model to identify possible reasons for this discrepancy.

We consider massless Quantum Electrodynamics in the momentum scheme and carry forward an approach based on Dyson–Schwinger equations to approximate both the β-function and the renormalized photon self-energy (Yeats, 2011). Starting from the Callan–Symanzik equation, we derive a renormalization group (RG) recursion identity which implies a non-linear ODE for the anomalous dimension and extract a sufficient but not necessary criterion for the existence of a Landau pole. This criterion implies a necessary condition for QED to have no such pole. Solving the differential equation exactly for a toy model case, we integrate the corresponding RG equation for the running coupling and find that even though the β-function entails a Landau pole it exhibits a flat contribution capable of decreasing its growth, in other cases possibly to the extent that such a pole is avoided altogether. Finally, by applying the recursion identity, we compute the photon propagator and investigate the effect of flat contributions on both spacelike and timelike photons. -- Highlights: •We present an approach to approximate both the β-function and the photon self-energy. •We find a sufficient criterion for the self-energy to entail the existence of a Landau pole. •We study non-perturbative ‘flat’ contributions that emerge within the context of our approach. •We discuss a toy model and how it is affected by flat contributions.

Three novel tetranuclear copper(II) complexes namely [Cu 4 (L 1 ) 4 ]∙2(dmf) (1), [Cu 4 (L 1 ) 4 ] (2) and [Cu 4 (L 2 ) 2 (HL 2 ) 2 (H 2 O) 2 ]∙2(ClO 4 )·6(H 2 O) (3) (H 2 L 1 , (E)−2-((1-hydroxybutan-2-ylimino)methyl)phenol; H 2 L 2 , (E)−2-((1-hydroxybutan-2-ylimino)methyl)−6-methoxyphenol)) were synthesized from the self-assembly of copper(II) perchlorate and the tridentate Schiff base ligands. The structural determination reveals that crystallizes in the monoclinic system with space group C2/c, whereas both the and crystallize in the triclinic system with space group P-1. and possess face-sharing dicubane core, on the other hand complex 3 has double open cubane core structure. The copper(II) ions in the cubane core are in distorted square planar geometries, and weak π…π and C–H…π interactions lead to formation of a 2D supramolecular architecture for and . At room temperature and , exhibit fluorescence with a quantum yield (Φ s ) of 0.47, 0.49 and 0.38, respectively. Variable temperature magnetic susceptibility measurements in the range 2–300 K indicate an overall weak antiferromagnetic exchange coupling in all complexes. The PHI program was used to study their magnetic behaviour. In agreement with their face-sharing dicubane structure, a Hamiltonian of the type H =– J 1 (S 1 S 2 +S 1 S 2’ +S 1' S 2 +S 1' S 2’ ) – J 2 S 1 S 1’ , where S 1 = S 1’ = S 2 = S 2’ = S Cu =1/2, was used for studying and . Simulations performed suggest magnetic exchange constants with values close to J 1 =−20 cm −1 and J 2 =0 cm -1 for these complexes. On the other hand, the spin Hamiltonian H =– J 1 (S 1 S 4 +S 2 S 3 ) – J 2 (S 1 S 3 +S 2 S 4 ) – J 3 S 1 S 2 , where S 1 = S 2 = S 3 = S 4 = S Cu =1/2, was used to study the magnetic behaviour of the double open cubane core of and a good agreement between the experimental and simulated results was found by using the parameters g 1 = g 2 =2.20, g 3 = g 4 =2.18, J 1 =−36 cm -1 , J 2

The potassium 40 constitutes the main source natural present in the organism that influences in the effective dose that people receive. With the objective of evaluating the contribution from this component to the doses received by the Cuban population, a study was developed in order to evaluate the doses for this cause. A representative sample was selected based on the distribution of Cuban population by sex and ages. The measurements were carried out in the Whole Body Counter of the Center for Radiation Protection and Hygiene. For the estimate of the doses an uniform distribution of potassium was assumed in the whole body and the methodology was used recommended by the ICRP. The values of annual effective dose varies between 93 and 209 mSv for the feminine sex and 102 and 212 mSv for the masculine sex. With the obtained values they were the adjustment coefficients for the functions dose-age for each one of the sexes. At the same time it was possible to model the estimate of the doses by means of a neural network that, trained with the obtained experimental data, it allows to estimate the due doses directly to the potassium 40 starting from the sex data, age, height and corporal weight. The effective dose mediates yearly for the public's members it was estimated in 149 ± 6 mSv, starting from the experimental data and the Cuban population's specific characteristics. (author)

Carrier Phase GPS Navigation to the North Pole

Science.gov (United States)

Moore, T.; Roberts, G. W.

Over the last few years, on-the-fly integer ambiguity resolution for GPS has proven to be successful over short baselines (500 km. New techniques have been developed at the University of Nottingham to allow very long baseline integer ambiguity resolution, on-the-fly. A major problem with the use of carrier phase data is that posed by cycle slips. A technique for detecting and correcting cycle slips has been developed, and its use is discussed in this paper. The new technique has been proven through a series of trials, one of which included two flights to the North Pole, performing centimetric level positioning all the way to the pole. For many years, the GD Aero-Systems Course of the Air Warfare Centre based at RAF Cranwell executed a series of equipment flight trials to the North Pole, called the ARIES Flights. In May 1996, the authors were fortunate to take part in both flights, via Iceland and Greenland, to the North Pole. Based on reference stations at Thule Air Base, integer ambiguity resolution was accomplished, on-the-fly, and centimetric level navigation maintained throughout the flights. Earlier trials detailed in the paper demonstrate that the technique can resolve integer ambiguities on-the-fly within a few seconds over a baseline length of approximately 134 km, resulting in an accuracy of 12 cm. The majority of the residual error source for this being the ionosphere.

We propose an integrated fiber Michelson interferometer based on a poled hollow twin-core fiber. The Michelson interferometer can be used as an electro-optic modulator by thermal poling one core of the twin-core fiber and introducing second-order nonlinearity in the fiber. The proposed fiber Michelson interferometer is experimentally demonstrated under driving voltages at the frequency range of 149 to 1000 Hz. The half-wave voltage of the poled fiber is 135 V, and the effective second-order nonlinear coefficient χ² is 1.23 pm/V.

Consanguineous marriage--marriage between relatives--has received a great deal of attention as a potential risk factor for many adverse health outcomes. The present cross-sectional study was done in order to illustrate the prevalence and types of consanguineous marriages among Iranian Georgians living in Frydoonshahr (Isfahan province, central Iran). Data on consanguineous marriages were collected using a simple questionnaire. The total number of couples in this study was 646. Consanguineous marriage was classified by the degree of relationship between couples. First cousin marriages (14.2%) were the most common type of consanguineous marriages, followed by second cousin (7.0%), beyond second cousin (1.5%) and first cousin once removed (0.6%). The mean inbreeding coefficient (α) was calculated as 0.0104 for the population. The present study shows that the study population, as other Iranian populations, has a high level of consanguinity.

The Anglo-Iranian oil dispute

International Nuclear Information System (INIS)

Ferrier, R.W.

1988-01-01

This paper traces the history of the Anglo-Iranian oil dispute. It is short-sighted to consider the Anglo-Iranian oil dispute just as a contest between Musaddiq and the AIOC: it is of wider and greater significance. The dispute illustrates a transitional phase in the difficult process of the adjustment of relations between industrialized and less developed societies for the exploitation of raw materials. Oil was already becoming a political and economic factor at the end of the Qajar period and became important during the reign of Riza Shah with his emphasis on a national program of modernization. After more attention had been focused on it during the second world war it was inevitable that it would increase in influence. The issues of the oil dispute referred back to the concessional controversies of the late nineteenth century in tobacco, mining, communications, utilities, banking even gambling, with their political and social implications; and they referred forward to the issues of the sovereignty of national resources, the transfer of technology and economic growth in relation to the standard of living. These are aspects of the North-South debate, which have yet to be satisfactorily resolved

2017-11-01

Composites of lead zirconate titanate particles in an epoxy matrix are prepared in the form of 0-3 and quasi 1-3 with different ceramic volume contents from 10% to 50%. Two different processing routes are tested. Firstly a conventional dielectrophoretic structuring is used to induce a chain-like particle configuration, followed by curing the matrix and poling at a high temperature and under a high voltage. Secondly a simultaneous combination of dielectrophoresis and poling is applied at room temperature while the polymer is in the liquid state followed by subsequent curing. This new processing route is practiced in an uncured thermoset system while the polymer matrix still possess a relatively high electrical conductivity. Composites with different degrees of alignment are produced by altering the magnitude of the applied electric field. A significant improvement in piezoelectric properties of quasi 1-3 composites can be achieved by a combination of dielectrophoretic alignment of the ceramic particles and poling process. It has been observed that the degree of structuring as well as the functional properties of the in-situ structured and poled composites enhance significantly compared to those of the conventionally manufactured structured composites. Improving the alignment quality enhances the piezoelectric properties of the particulate composites.

This is a bibliometric study using the Scopus database as data source, using search affiliation address relevant to traditional medicine and Iran as the search strategy. Subject and geographical overlay maps were also applied to visualize the network activities of the Iranian authors. Highly cited articles (citations >10) were further explored to highlight the impact of research domains more specifically. About 3,683 articles were published by Iranian authors in Scopus database. The compound annual growth rate of Iranian publications was 0.14% during 2010-2014. Tehran University of Medical Sciences (932 articles), Shiraz University of Medical Sciences (404 articles) and Tabriz Islamic Medical University (391 articles), were the leading institutions in the field of traditional medicine. Medicinal plants (72%), digestive system's disease (21%), basics of traditional medicine (13%), mental disorders (8%) were the major research topics. United States (7%), Netherlands (3%), and Canada (2.6%) were the most important collaborators of Iranian authors. Iranian research efforts in the field of traditional medicine have been increased slightly over the last years. Yet, joint multi-disciplinary collaborations are needed to cover inadequately described areas of traditional medicine in the country.

Mohammad Hadi Daraei

2015-05-01

Full Text Available Pacta sunt servanda” is one of the most fundamental principles in the common law and Iranian legal systems, which have been exposed to exceptions in the process of time. These exceptions are part of general doctrine of frustration. Iranians exceptions to this rule are named as “Ta`azzor” and “Ta`assor” rules. Doctrine of Frustration in Common law includes three subdivision theories: “impossibility of performance”, “frustration of purpose” and “impracticability” (hardship. All of these theories applied where a supervening event occurs. In English courts, only first two theories are accepted but third one is applicable in American courts. In imamieh Jurisprudence and Iranian law, “Ta`azzor” rule in most aspects is similar to Impossibility and “Ta`assor” rule is somehow like Impracticability. Some Iranian lawyers are said that we have no rule like “Frustration of Purpose” but I believe we can find traces of this theory in Imamieh jurisprudence and according which it is part of “Ta`azzor” rule.

Objective(s): From the ancient era, emergence of Agriculture in the connecting region of Mesopotamia and the Iranian plateau at the foothills of the Zagros Mountains, made Iranian gene pool as an important source of populating the region. It has differentiated the population spread and different language groups. In order to trace the maternal genetic affinity between Iranians and other populations of the area and to establish the place of Iranians in a broad framework of ethnically and linguistically diverse groups of Middle Eastern and South Asian populations, a comparative study of territorial groups was designed and used in the population statistical analysis. Materials and Methods: Mix of 616 samples was sequenced for complete mtDNA or hyper variable regions in this study. A published dataset of neighboring populations was used as a comparison in the Iranian matrilineal lineage study based on mtDNA haplogroups. Results: Statistical analyses data, demonstrate a close genetic structure of all Iranian populations, thus suggesting their origin from a common maternal ancestral gene pool and show that the diverse maternal genetic structure does not reflect population differentiation in the region in their language. Conclusion: In the aggregate of the eastward spreads of proto-Elamo-Dravidian language from the Southwest region of Iran, the Elam province, a reasonable degree of homogeneity has been observed among Iranians in this study. The approach will facilitate our perception of the more detailed relationship of the ethnic groups living in Iran with the other ancient peoples of the area, testing linguistic hypothesis and population movements.

Full Text Available The aim of this study was to determine the presence of Helicobacter pylori cytotoxin-associated gene (cagA/vacuolating cytotoxin gene (vacA among patients with chronic gastritis in Cuba and Venezuela. Gastric antrum biopsies were taken for culture, DNA extraction and PCR analysis. Amplification of vacA and cagA segments was performed using two regions of cagA: 349 bp were amplified with the F1/B1 primers and the remaining 335 bp were amplified with the B7629/B7628 primers. The VA1-F/VA1-R set of primers was used to amplify the 259-bp (s1 or 286-bp (s2 product and the VAG-R/VAG-F set of primers was used to amplify the 567-bp (m1 or 642-bp (m2 regions of vacA. cagA was detected in 87% of the antral samples from Cuban patients and 80.3% of those from Venezuelan patients. All possible combinations of vacA regions were found, with the exception of s2/m1. The predominant combination found in both countries was s1/m1. The percentage of cagA+ strains was increased by the use of a second set of primers and a greater number of strains was amplified with the B7629/B7628 primers in the Cuban patients (p = 0.0001. There was no significant difference between the presence of the allelic variants of vacA and cagA in both populations. The predominant genotype was cagA+/s1m1 in both countries. The results support the necessary investigation of isolates circulating among the human population in each region.

Full Text Available Academicians are identified with their papers and expertise in writing scholarly articles, either for promotion or for satisfying their prestige. Iranian academic members are expected to win a justifiable stance by the quality and quantity of their publications and presentations. Regrettably through pervious studying about second language writing, any studies haven’t been dedicated to the style of writing articles, which are used by academic members. Former studies on second language writing indicate that style in academic paper writing is most likely ignored. The purpose of this study is to explore the role of mind translation strategy among Iranian academic members for expressing their own opinion through writing second language academic papers. The present paper has based its hypothesis on three levels of strategies, effective in writing academic papers, namely: 1-Do Iranian academicians follow specific strategies in writing their academic papers? 2-What role does translation play as a strategy in their writing academic papers? 3-Do they feel a need for a strategy shift in their academic paper writing? Data elicited based on survey and corpora analysis in form of CBDTS- on micro and macro levels, are put into matrices and their analyses are supportive of academicians’ reliance on different types of mental translation use and their shift toward authentic writing after receiving feedback from their reviewers.

In this Letter, we report the monitoring of seasonal evolution near Titan’s poles. We find Titan’s south pole to exhibit since 2010 a strong temperature decrease and a dramatic enhancement of several trace species such as complex hydrocarbons and nitriles (HC3N and C6H6 in particular) previously only observed at high northern latitudes. This results from the seasonal change on Titan going from winter (2002) to summer (2017) in the north and, at the same time, the onset of winter in the south pole. During this transition period atmospheric components with longer chemical lifetimes linger in the north, undergoing slow photochemical destruction, while those with shorter lifetimes decrease and reappear in the south. An opposite effect was expected in the north, but not observed with certainty until now. We present here an analysis of high-resolution nadir spectra acquired by Cassini/Cassini Composite Infrared Spectrometer in the past years and describe the temperature and composition variations near Titan’s poles. From 2013 until 2016, the northern polar region has shown a temperature increase of 10 K, while the south has shown a more significant decrease (up to 25 K) in a similar period of time. While the south polar region has been continuously enhanced since about 2012, the chemical content in the north is finally showing a clear depletion for most molecules only since 2015. This is indicative of a non-symmetrical response to the seasons in Titan’s stratosphere that can set constraints on photochemical and GCM models.

Full text: Five years ago we started a National Program of Quality Assurance in Radiotherapy. This program was possible thanks to the cooperation between the Cuban Ministry of Health and the International Atomic Energy Agency (IAEA) in the Projects ARCAL XXX and CUB/6/011. In the framework of these projects a total of ten complete dosimetry set were acquired and a large number of medical physicists were trained. At the same time, the Cuban side signed a contract for nine cobalt units, which have been gradually installed and all of them are running at the moment. During more than 20 years Cuba has taken part in the IAEA/WHO TLD postal dose audit programs and our results have been inside the (+/-)5 % acceptance limit. Cuba also joined the IAEA Coordinated Research Program E2 40 07, to extend at a national level the experience of the TLD based audits, using the capability of our SSDL to measure TLD. At the same time the work of the already existing External Audit Group was consolidated. The National Program of Quality Assurance in Radiotherapy works on base of external on-site visits. The main objective is to avoid any accident and to improve the quality of the RT treatments. Every year each Radiotherapy service is visited by a qualified team of physicists with the objective to check the physical aspects of the quality of the RT treatment, it includes: Documents and Records, safety, mechanical and dosimetric aspects, treatment planning, also we use the fixed depth phantom to simulate and verify several techniques. Although the TLD postal audit results are acceptable, in our QA audits we have detected some problems that may deviate the dose delivery to patients in more than 5%, examples of which are: Not all the clinical plans are redundantly checked by an independent person; Not all the controls (daily, monthly and annual) are performed according to the protocols approved by the National QA Committee. In some cases the controls are not well recorded; Clinical

Eleven elite XC skiers performed DP at 85% of their maximal DP velocity (V85%) during roller skiing at 1 degrees inclination on a treadmill. Pole and plantar ground reaction forces, joint angles (elbow, hip, knee, and ankle), cycle characteristics, and electromyography (EMG) of upper and lower body muscles were analyzed. 1) Pole force pattern with initial impact force peak and the following active force peak (PPF) correlated to V85%, (r = 0.66, P biomechanical aspects. Future research should further investigate the relationship between biomechanical and physiological variables and elaborate training models to improve DP performance.

Non-uniformly sampled grids in double pole coordinate system for freeform reflector construction

Science.gov (United States)

Ma, Donglin; Pacheco, Shaun; Feng, Zexin; Liang, Rongguang

2015-08-01

We propose a new method to design freeform reflectors by nonuniformly sampling the source intensity distribution in double pole coordinate system. In double pole coordinate system, there is no pole for the whole hemisphere because both poles of the spherical coordinate system are moved to southernmost point of the sphere and overlapped together. With symmetric definition of both angular coordinates in the modified double pole coordinate system, a better match between the source intensity distribution and target irradiance distribution can be achieved for reflectors with large acceptance solid angle, leading to higher light efficiency and better uniformity on the target surface. With non-uniform sampling of the source intensity, we can design circular freeform reflector to obtain uniform rectangular illumination pattern. Aided by the feedback optimization, the freeform reflector can achieve the collection efficiency for ideal point source over 0.7 and relative standard deviation (RSD) less than 0.1.

The current design of the Advanced Photon Source Upgrade (APS-U) project is a multi-bend achromat (MBA) lattice, which incorporates three-pole wigglers as radiation sources for the bending magnet beamlines. They are located in the short section between the M4 dipole and Q8 quadrupole magnets. Due to space constraints, a hybrid permanent magnet design is necessary to provide the required magnetic field strength. A three-pole wiggler with a flat peak field profile along the beam axis was designed to enhance the photon flux and flatten the transverse flux density distributions. The magnetic peak field at the center pole reached 1.08 Tesla for a magnetic gap of 26 mm. The maximum power density, integrated over all vertical angles, is 3.1 W/mm{sup 2}, which is substantially higher than that of the existing bending magnets at the APS (0.86 W/mm{sup 2}). Detailed designs of the three-pole wiggler is presented, including calculated spectral-angular flux distributions.

Mankinen, E.A.

1989-01-01

Paleomagnetic sampling of the Miocene and Pliocene Sonoma Volcanics, northern California, was undertaken to supplement an earlier collection. Data from 25 cooling units yield positive fold and reversal tests, and a paleomagnetic pole located at 80.2??N., 069.2??E., with ??95 = 6.8??. This paleopole is significantly displaced (9.6?? ?? 5.3?? of latitude) to the farside of the geographic pole. A highly elliptical distribution of the data in both direction and VGP space indicates that incomplete averaging of geomagnetic secular variation is a more likely explanation for this anomaly than is northward translation of the volcanic field. -Author

2016-03-01

Full Text Available Background Melasma (called Kalaf in Iranian traditional medicine is a common acquired hypermelanosis that affects sun-exposed areas of skin. Several factors including exposure to sunlight, pregnancy, and endocrine diseases increase the risk for Melasma. In traditional medicine, antecedent philosophers and physicians have tried to understand the nature and mechanisms of different systems of the human body for the diagnosis and management of Melasma; they have offered different solutions for it. This study is important since Melasma is a disease causing mental side effects in patients, due to darkness and opacity of the skin; therefore, the treatment of Melasma in terms of its psychological complications is of particular importance. In addition, texts of Iranian traditional medicine contain a wealth of nutritional advice for patients with Melasma. These texts have, until now, not yet been reviewed. The present study has considered the most important references of Iranian traditional medicine texts. Objectives The objective of this study was to extract and categorize the nutritional advice of Iranian traditional medicine texts for the treatment of Melasma. Results Dietary recommendations, not only for treatment but also for prevention of diseases and staying healthy, are very efficient. Conclusions Based on the traditional medicine texts, it is helpful to avoid Soda-producing food as well as to identify appropriate food in order to eliminate the accumulation of Soda or black bile from the blood. This study offers a set of analytical and clinical research on food, which in traditional medicine is called Soda-producing as well as Soda reducing.

Context: Functional dyspepsia (FD) is a functional gastro-intestinal disorder with high prevalence. Among various treatment options, treatment by complementary and alternative medicines especially herbal remedies also practiced. Traditional Iranian medicine (TIM), a valuable resource of valid applied studies of ancient Iranian scholars, recommends numerous medicinal plants to treat dyspepsia symptoms. In this study, through investigation of TIM references, we aimed to identify medicinal plants for treatment of digestion insufficiency. Evidence Acquisition: In this qualitative study, dyspepsia symptoms including fullness, early satiety, bloating, nausea, and belching were checked under reliable sources of traditional medicine. Then medicinal plants recommended for the treatment of the symptoms were extracted from the books. Likewise, for investigating the pharmacological properties of medicinal plants used for the relieving of dyspepsia symptoms, electronic databases such as PubMed, Scopus, Google Scholar and some Iranian databases like SID and IranMedex were employed. Results: The study yielded 105 plants from 37 families which could treat various dyspepsia symptoms; fifty-seven plants, mainly from Apiaceae, Lamiaceae, Amaryllidaceae and Zingiberaceae had digestive effects. In this research, based on the information in TIM reference texts, we obtained 58 plants effective for bloating, 40 for nausea, 37 for appetite loss and 7 for belching. In human clinical trials conducted on medicinal plants effective for FD symptoms, 7 single plants were used. Conclusions: Finding the medicinal plants effective on digestion insufficiency based on TIM could suggest a better strategy for the relieving of dyspepsia symptoms. Traditional Iranian medicine prescribes medicinal plants based on each patient’s personal characteristics and practices multiple target therapies. PMID:26734483

A novel tetranuclear copper(II) complex (1) was synthesized from the self-assembly of copper(II) perchlorate and the ligand N-benzyl-1-(2-pyridyl)methaneimine (L(1)). Single-crystal X-ray diffraction studies revealed that complex 1 consists of a Cu4(OH)4 cubane core, where the four copper(II) centers are linked by μ3-hydroxo bridges. Each copper(II) ion is in a distorted square-pyramidal geometry. X-ray analysis also evidenced an unusual metal cation-π interaction between the copper ions and phenyl substituents of the ligand. Calculations based on the density functional theory method were used to quantify the strength of this metal-π interaction, which appears as an important stabilizing parameter of the cubane core, possibly acting as a driving parameter in the self-aggregation process. In contrast, using the ligand N-phenethyl-1-(2-pyridyl)methaneimine (L(2)), which only differs from L(1) by one methylene group, the same synthetic procedure led to a binuclear bis(μ-hydroxo)copper(II) complex (2) displaying intermolecular π-π interactions or, by a slight variation of the experimental conditions, to a mononuclear complex (3). These complexes were studied by X-ray diffraction techniques. The magnetic properties of complexes 1 and 2 are reported and discussed.

Although the {CaMn4O5} oxygen evolving complex (OEC) of photosystem II is a major paradigm for water oxidation catalyst (WOC) development, the comprehensive translation of its key features into active molecular WOCs remains challenging. The [Co(II)3Ln(hmp)4(OAc)5H2O] ({Co(II)3Ln(OR)4}; Ln = Ho-Yb, hmp = 2-(hydroxymethyl)pyridine) cubane WOC series is introduced as a new springboard to address crucial design parameters, ranging from nuclearity and redox-inactive promoters to operational stability and ligand exchange properties. The {Co(II)3Ln(OR)4} cubanes promote bioinspired WOC design by newly combining Ln(3+) centers as redox-inactive Ca(2+) analogues with flexible aqua-/acetate ligands into active and stable WOCs (max. TON/TOF values of 211/9 s(-1)). Furthermore, they open up the important family of 3d-4f complexes for photocatalytic applications. The stability of the {Co(II)3Ln(OR)4} WOCs under photocatalytic conditions is demonstrated with a comprehensive analytical strategy including trace metal analyses and solution-based X-ray absorption spectroscopy (XAS) investigations. The productive influence of the Ln(3+) centers is linked to favorable ligand mobility, and the experimental trends are substantiated with Born-Oppenheimer molecular dynamics studies.

Diagonal skiing as a major classical technique has hardly been investigated over the last two decades, although technique and racing velocities have developed substantially. The aims of the present study were to 1) analyse pole and leg kinetics and kinematics during submaximal uphill diagonal roller skiing and 2) identify biomechanical factors related to performance. Twelve elite skiers performed a time to exhaustion (performance) test on a treadmill. Joint kinematics and pole/plantar forces were recorded separately during diagonal roller skiing (9 degrees; 11 km/h). Performance was correlated to cycle length (r = 0.77; P Push-off demonstrated performance correlations for impulse of leg force (r = 0.84), relative duration (r= -0.76) and knee flexion (r = 0.73) and extension ROM (r = 0.74). Relative time to peak pole force was associated with performance (r = 0.73). In summary, diagonal roller skiing performance was linked to 1) longer cycle length, 2) greater impulse of force during a shorter push-off with larger flexion/extension ROMs in leg joints, 3) longer leg swing, and 4) later peak pole force, demonstrating the major key characteristics to be emphasised in training.

Ancient migratory events in the Middle East: new clues from the Y-chromosome variation of modern Iranians.

Directory of Open Access Journals (Sweden)

Viola Grugni

Full Text Available Knowledge of high resolution Y-chromosome haplogroup diversification within Iran provides important geographic context regarding the spread and compartmentalization of male lineages in the Middle East and southwestern Asia. At present, the Iranian population is characterized by an extraordinary mix of different ethnic groups speaking a variety of Indo-Iranian, Semitic and Turkic languages. Despite these features, only few studies have investigated the multiethnic components of the Iranian gene pool. In this survey 938 Iranian male DNAs belonging to 15 ethnic groups from 14 Iranian provinces were analyzed for 84 Y-chromosome biallelic markers and 10 STRs. The results show an autochthonous but non-homogeneous ancient background mainly composed by J2a sub-clades with different external contributions. The phylogeography of the main haplogroups allowed identifying post-glacial and Neolithic expansions toward western Eurasia but also recent movements towards the Iranian region from western Eurasia (R1b-L23, Central Asia (Q-M25, Asia Minor (J2a-M92 and southern Mesopotamia (J1-Page08. In spite of the presence of important geographic barriers (Zagros and Alborz mountain ranges, and the Dasht-e Kavir and Dash-e Lut deserts which may have limited gene flow, AMOVA analysis revealed that language, in addition to geography, has played an important role in shaping the nowadays Iranian gene pool. Overall, this study provides a portrait of the Y-chromosomal variation in Iran, useful for depicting a more comprehensive history of the peoples of this area as well as for reconstructing ancient migration routes. In addition, our results evidence the important role of the Iranian plateau as source and recipient of gene flow between culturally and genetically distinct populations.

Full Text Available ine"> Cuban crude in the process of leaching, sedimentation and distillation ofthe processed minerals at “René Ramos Latour” Company was evaluated. Two periods of testswere performed; one when oil was introduced into the furnace by spear and the other when itwas introduced by spear and chamber. The results demonstrated the feasibility of using theCuban crude in reduction and leaching process of mineral by the use of spear and chamber aswell. Nickel and cobalt extractions achieved by stepwise exceed values found in the relatedliterature. Deposition of mineral was good reaching values of 1,736 -1,745 kg/m3 at the bottomof the sedimentation stage leach and 1,774 -1,807 kg/m3 in the washing stage. The thickenerswere maintained with high clear liquor level throughout the test with values between 28,0-30,0ppm. The sedimentation rate achieved low values both in the first and in the second leachingstage. Sedimentation unit area was 0,23 m2 /T day, so that no sedimentation problems werepresented. It was observed an increase in the sulfur content up to values of 6,52 g/L for a nickelcontent of 12,0g/L, which caused that the dissolved nickel in downloading stills were of 0,392 g/L and 2,58 g/L of ammonia. The sulfur content in the nickel carbonate was increased upto 6,30 %, which is 2,5 % higher than conventional.

The Antarctic and Arctic regions offer a unique opportunity to test factors shaping biogeography of marine microbial communities because these regions are geographically far apart, yet share similar selection pressures. Here, we report a comprehensive comparison of bacterioplankton diversity between polar oceans, using standardized methods for pyrosequencing the V6 region of the small subunit ribosomal (SSU) rRNA gene. Bacterial communities from lower latitude oceans were included, providing a global perspective. A clear difference between Southern and Arctic Ocean surface communities was evident, with 78% of operational taxonomic units (OTUs) unique to the Southern Ocean and 70% unique to the Arctic Ocean. Although polar ocean bacterial communities were more similar to each other than to lower latitude pelagic communities, analyses of depths, seasons, and coastal vs. open waters, the Southern and Arctic Ocean bacterioplankton communities consistently clustered separately from each other. Coastal surface Southern and Arctic Ocean communities were more dissimilar from their respective open ocean communities. In contrast, deep ocean communities differed less between poles and lower latitude deep waters and displayed different diversity patterns compared with the surface. In addition, estimated diversity (Chao1) for surface and deep communities did not correlate significantly with latitude or temperature. Our results suggest differences in environmental conditions at the poles and different selection mechanisms controlling surface and deep ocean community structure and diversity. Surface bacterioplankton may be subjected to more short-term, variable conditions, whereas deep communities appear to be structured by longer water-mass residence time and connectivity through ocean circulation.

Full Text Available Taking scale as an object of analysis (Tsing 2000, this article examines how competing scale-making projects emerge in different layers of the Cuban tourism economy. I consider how tourists and Cubans interact along contested chains of production and distribution of cigars, and therefore become entangled in bundles of ideas, discourses, practices and materialities. These constitute different scaling propositions on which tourists and Cubans converge or diverge, and which inform the success of encounters within the tourism economy. Highlighted is the importance of understanding how scaling propositions are enacted and negotiated within tourism. I conclude that the realm of tourism is a particularly fruitful platform to investigate how competing scale-making projects and notions of scale are played out in the contemporary world.Tomando a escala (Tsing 2000 como objecto de análise, este artigo aborda a forma como emergem projectos concorrentes de configuração de escala a diferentes níveis da economia turística cubana. É examinada a interacção de turistas e cubanos no âmbito de cadeias de produção e distribuição controversas, e as formas como, assim, uns e outros se envolvem em conjuntos de ideias, discursos, práticas e materialidades. Estes constituem diferentes propostas de configuração de escala em que turistas e cubanos convergem ou divergem e que determinam o sucesso dos encontros no seio da economia turística. É aqui sublinhada a importância de compreendermos como as propostas de configuração de escala são apresentadas e negociadas no âmbito do turismo. Conclui-se que o campo do turismo constitui uma plataforma particularmente fértil para o estudo de como noções de escala e projectos de configuração de escala concorrentes se desenvolvem no mundo contemporâneo.

Making decision on not to resuscitate is a confusing, conflicting and complex issue and depends on each country's culture and customs. Therefore, each country needs to take action in accordance with its cultural, ethical, religious and legal contexts to develop guidelines in this regard. Since the majority of Iran's people are Muslims, and in Islam, the human life is considered sacred, based on the values of the community, an Iranian Islamic agenda needs to be developed not taking measures about resuscitation of dying patients. It is necessary to develop an Iranian Islamic guidelines package in order to don't resuscitate in dying patients.

Fragmentary ossification of the inferior patella is often dismissed as a normal variant in children younger than 10 years of age. The purpose of this study was to determine whether fragmentary inferior patellar pole ossification is a normal variant or is associated with symptoms or signs of pathology using MRI and clinical exam findings as reference. A retrospective review was performed on 150 patients ages 5-10 years who underwent 164 knee radiography and MRI exams (45.1% male, mean age: 7.8 years). The presence or absence of inferior patellar pole fragmentation on radiography was correlated with the presence or absence of edema-like signal on MR images. Clinical notes were reviewed for the presence of symptoms or signs referable to the inferior patellar pole. These data were compared with a 1:1 age- and sex-matched control group without inferior pole fragmentation. Statistical analysis was performed using two-tailed t-tests. Forty of 164 (24.4%) knee radiographs showed fragmentary ossification of the inferior patella. Of these 40 knees, 62.5% (25/40) had edema-like signal of the inferior patellar bone marrow compared with 7.5% (3/40) of controls (P = 0.035). Patients with fragmentary ossification at the inferior patella had a significantly higher incidence of documented focal inferior patellar pain compared with controls (20% vs. 2.5%, P = 0.015). Inferior patellar pole fragmentation in children 5 to 10 years of age may be associated with localized symptoms and bone marrow edema-like signal and should not be routinely dismissed as a normal variant of ossification.

The Tibetan Plateau and surrounding mountain ranges, referred to by scientists as the Third Pole (TP), represent one of the largest ice masses of the Earth. The region is one of the most sensitive areas responding to global climate change due to its high altitude and the presence of permafrost and glaciers. The near 100,000 km2 of glaciers ensure the permanent flow of major rivers in this region and provide water to 1.4 billion people in Asia. Thus, environmental changes taking place on the TP significantly influences social and economic development of countries in this region such as China, India, Nepal, Tajikistan, Pakistan, Afghanistan and Bhutan. With an average elevation higher than 4,000 metres above sea level, the Third Pole is characterized by complex interactions of atmospheric, cryospheric, hydrological, geological and environmental processes that bear special significance for the Earth's biodiversity, climate and water cycles. For a comprehensive understanding of the environment of the TP and its implications on the development of the region, we need to integrate different disciplines under a them of 'water-ice-air-ecosystem -human' interactions and reveal environmental change processes and mechanisms on the TP and their influences on and regional responses to global changes, and thus to serve for enhancement of human adaptation to the changing environment. Like Antarctica and the Arctic, the Third Pole region is drawing increased attention of the international academic community. A series of observations and monitoring programs in the Third Pole region has been widely implemented. However, data necessary to precisely assess the environmental, societal and economic changes caused by alterations in the Third Pole dynamics are either lacking or insufficient. The Third Pole Environment (TPE) program is thus established as a comprehensive and coordinated international research, monitoring and capacity building initiative, with goals to address the influence

Full Text Available Extensive studies in the fields of culture and parenting in recent years have shown that parent’s goals and values of parenting lead to differences in their parental behaviors. This study was designed to observe Iranian mothers’ interaction with their children in a playing situation. This study was a qualitative study in which 30 pairs of mothers and children (15 girls and 15 boys were selected purposely. To observe the parent-child interaction, a playing situation was designed and recorded by video camera. Observational data were analyzed based on qualitative analysis methods. Through coding and categorizing the observed data of the parent-child interaction, verbal (positive, negative and facilitator and nonverbal (positive, negative and communicative behavioral patterns were extracted and named by the investigator. Based on scoring the determined codes, facilitator verbal behaviors and negative nonverbal behaviors were the most frequent. The mothers’ behavior that facilitated child’s playing process and diminished child’s practical and mental activities were named facilitator behaviors, and were the most frequent among Iranian mothers. Based on the same previous research, Iranian mothers’ parenting behaviors are similar to those of Japanese, Chinese and Latin mothers rather than American, British and Australian mothers.

Full Text Available The paper is intended to portray the most important qualities and attitudes that distinguish the model of a teacher’s training school, a project for educating would-be teachers for Kindergarten, Primary School and Special Education. The idea that Cuban Pedagogy is a natural source of ideas for sustaining such model as well as characterizing social agents’ attitudes and the institution’s features is argued. A logical-historic analysis is carried out, starting by considering some of the most important Cuban school teachers’ criteria, from which the author infers the qualities and ethical attitudes that characterize the social participants and the whole institution.

Fault Current Distribution and Pole Earth Potential Rise (EPR) Under Substation Fault

Science.gov (United States)

Nnassereddine, M.; Rizk, J.; Hellany, A.; Nagrial, M.

2013-09-01

New high-voltage (HV) substations are fed by transmission lines. The position of these lines necessitates earthing design to ensure safety compliance of the system. Conductive structures such as steel or concrete poles are widely used in HV transmission mains. The earth potential rise (EPR) generated by a fault at the substation could result in an unsafe condition. This article discusses EPR based on substation fault. The pole EPR assessment under substation fault is assessed with and without mutual impedance consideration. Split factor determination with and without the mutual impedance of the line is also discussed. Furthermore, a simplified formula to compute the pole grid current under substation fault is included. Also, it includes the introduction of the n factor which determines the number of poles that required earthing assessments under substation fault. A case study is shown.

Improved technology for spun-cast concrete poles

Energy Technology Data Exchange (ETDEWEB)

Dilger, W H; Ghali, A

1984-07-01

Different types of concrete were investigated with the goal of developing concrete suitable for the production of spun-cast concrete poles. A total of 65 different concrete mixes were investigated, with the suitability criteria defined as: compactability, no segregation of the mix components during the spinning operation, no shrinkage cracking, high strength, and durability. High strength normal weight concretes and semi-lightweight concretes, both with and without fly ash and/or silica fume and with different types of admixtures were used to produce spun-cast concrete pole segments. Of the 35 lightweight concretes only 3 were considered successful, as in all other specimens the inner layer of coarse aggregate was not well embedded in the mortar, and many mixes could not be compacted properly because they were too stiff, too wet, or started to set before spinning commenced. The three successful specimens contained fly ash and one contained silica fume, and had low water/cement ratios (0.26 to 0.29). Of the 23 normal weight concretes tested, only 5 were considered suitable, and all these had a sand/coarse aggregate ratio of 0.25 or smaller and a cement content between 350 and 400 kg/m{sup 3}. A theoretical study of the stresses in the end zones of pretensioned poles is presented. 10 refs., 53 figs., 14 tabs.

This image shows a rare clear view of the South Pole (lower right) and the Ross Sea, Antarctica. The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) acquired the scene on December 26, 2001. The geographic South Pole is located in the center of Antarctica, at an altitude of 2,900 meters (9,300 feet). It rests on a continent-wide ice sheet that is 2,870 m thick, with the underlying bedrock only 30 m (98 feet) above sea level. The ice underlying the South Pole is as much as 140,000 years old, and is currently accumulating at about 82 cm (32 inches) per year. Roughly 2,500 km (1,550 miles) away is the green water of the Ross Sea, which indicates the presence of large numbers of phytoplankton. This is a highly productive part of the world's oceans. Also note the ice gathered around McMurdo Sound, seen toward the lefthand shoreline of the Ross Sea, at the edge of the Ross Ice Shelf. According to National Science Foundation researchers, this ice is making it difficult for penguins to reach their food supply. Separating the continental Antarctic ice sheet from the Ross Sea are the Queen Maud Mountains and the Ross Ice Shelf.

Transmitting the sum of all fears: Iranian nuclear threat salience among offspring of Holocaust survivors.

Science.gov (United States)

Shrira, Amit

2015-07-01

Many Israelis are preoccupied with the prospect of a nuclear-armed Iran, frequently associating it with the danger of annihilation that existed during the Holocaust. The current article examined whether offspring of Holocaust survivors (OHS) are especially preoccupied and sensitive to the Iranian threat, and whether this susceptibility is a part of their increased general image of actual and potential threats, defined as the hostile world scenario (HWS). Study 1 (N = 106) showed that relative to comparisons, OHS reported more preoccupation with the Iranian nuclear threat. Moreover, the positive relationship between the salience of the Iranian threat and symptoms of anxiety was stronger among OHS. Study 2 (N = 450) replicated these findings, while focusing on the Iranian nuclear threat salience and symptoms of psychological distress. It further showed that OHS reported more negative engagement with the HWS (i.e., feeling that surrounding threats decrease one's sense of competence), which in turn mediated their increased preoccupation with the Iranian threat. The results suggest that intergenerational transmission of the Holocaust trauma includes heightened preoccupation with and sensitivity to potential threats of annihilation, and that the specific preoccupation with threats of annihilation reflects a part of a more general preoccupation with surrounding threats.

Full Text Available This study investigatesvariability in English yes/no questions as well as the commonalities among yes/no question variants produced by members of two different varieties of English: Canadian English native speakers and Iranian EFL learners.Further, it probes the role of gender in theEnglish yes/no question variants produced by Canadian English native speakers and those produced by Iranian EFL learners. A modified version of the Edinburgh Map Task was used in data collection. 60 Canadians and Iranians performed the task and made English yes/no question variants considering the informal context. Based on the results, the same types of yes/no question variants were produced by both groups. However, with respect to quantity, Canadians made more variants while the context of use was similar. Another difference noticed was the most frequent variant: Iranians’ frequent variant coincided with the informal context, yet the Canadians’ frequent variant did not. Regarding gender, Iranians did not produce any gender-based variant; while Canadians showed that their production of yes/no question variants was gender-oriented. These findings revealed that both Canadians and Iranians from two different varieties of English syntactically behaved similarly, but their sociolinguistic behavior was not the same.

The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. This is an applied study and uses descriptive - survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word "Digital Library" in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The "Help" in public services (48/48%) and "Interlibrary Loan" in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated, the leaders in providing different services are Library of

Full Text Available Background: Social health is a fundamental dimension of health, and plays an important role in promoting social well-being. Research in social health needs reliable and valid tools, which should be also applicable to any type of social context. This study was aimed to develop an effective social health questionnaire for the social context of Iranian society. Methods: The study was conducted in three phases: 1 A preliminary 43-item questionnaire was created based on an extensive literature review; 2 The questionnaire was validated. Firstly, social health experts evaluated content validity; secondly, an exploratory factor analysis and Cronbach’s coefficient test were used; 3 The questionnaire was tested in a representative sample of 500 persons, who were selected through a multistage sampling in Tehran, Iran, in 2015. All analyses were carried out using SPSS software (version 22. Results: We developed the Iranian Social Health Questionnaire (IrSHQ consisting of a 29-item questionnaire organized in seven subscales – ‘Social interaction’, ‘social responsibility’, ‘conscientiousness’, ‘attitude to society’, ‘empathy’, ‘family relationship’, and ‘social participation’−. Internal consistency using Cronbach’s alpha coefficient was 0.86. Validity and reliability of our questionnaire were confirmed. Conclusion: Due to the size and diversity of participants, validity of results, compliance with Iranian culture, and its relative shortness, the IrSHQ appears to be a very useful instrument for measuring individual’s social health in the Iranian social context.

Infertility is one of the most important reproductive health concerns in the conventional medicine. Iranian traditional medicine presents different viewpoints in this regard which they could be of benefit and a good guide for the society of medicine. This study sought to provide the comprehensive investigation on the causes of infertility according to Iranian traditional medicine for understanding of old sages' ideas and categorizing of the causes of infertility. In this narrative review, we searched causes of infertility in traditional medicine books and available articles in this field. Iranian traditional physicians have investigated the causes of infertility in couples and attributed them to male and female causes. They have divided the main causes of infertility in both sexes into structural and functional abnormalities, that both traditional medicine and conventional medicine have a lot of participations, but the traditional medicine believes holistic approach in the treatment of diseases and the involvement of all parts of the body particularly specialty board members (heart, liver, brain, ovary, and testicles) in the proper conduct activities in different parts of the body such as reproduction system. There is also special attention to temperament Mizaj disorders. Given the numerous commonalities existing between traditional and conventional medicine in categorizing the causes of infertility, Iranian traditional medicine methods can be applied as a complementary solution in infertility. It could be also subject to further research and investigation due to its opposition to modern medicine in some regards. PMID:28835934

Full Text Available The demographic dynamics analysed in the context of the relationship between economic development and social inclusion presents an image of the sustainable development of a community as well as the manner how the financial resources have been used. With an allocation of 74.3 million euro in the programming period 2007-2013, the Brasov Growth Pole has pursued the contribution to the achievement of sustainable development since 2005 by the participation in the Agenda 21. The implementation of projects with European financing in areas such as transport, social and educational infrastructure or tourism have generated changes/demographic movements, which this paper proposes to present. The evolution of the stable population, its dynamics at the level of each locality that is part of the Brasov growth pole as well as the dynamics of the number of employees or the development of the unemployment rate are presented by the cluster analysis. The effects of the European financing obtained from Regional Operational Programme 2007-2013 are thus reflected in the sustainable development of the Brasov growth pole from the point of view of the dynamics of the population

The catalytic subunit of DNA polymerase epsilon (POLE1) functions primarily in nuclear DNA replication and repair. Recently, POLE1 mutations were detected frequently in colorectal and endometrial carcinomas while with lower frequency in several other types of cancer, and the p.P286R and p.V411L mutations were the potential mutation hotspots in human cancers. Nevertheless, the mutation frequency of POLE1 in ovarian cancer still remains largely unknown. Here, we screened a total of 251 Chinese samples with distinct subtypes of ovarian carcinoma for the presence of POLE1 hotspot mutations by direct sequencing. A heterozygous somatic POLE1 mutation, p.S297F (c.890C>T), but not p.P286R and p.V411L hotspot mutations observed in other cancer types, was identified in 3 out of 37 (8.1%) patients with ovarian endometrioid carcinoma; this mutation was evolutionarily highly conserved from Homo sapiens to Schizosaccharomyces. Of note, the POLE1 mutation coexisted with mutation in the ovarian cancer-associated PPP2R1A (protein phosphatase 2, regulatory subunit A, α) gene in a 46-year-old patient, who was also diagnosed with ectopic endometriosis in the benign ovary. In addition, a 45-year-old POLE1-mutated ovarian endometrioid carcinoma patient was also diagnosed with uterine leiomyoma while the remaining 52-year-old POLE1-mutated patient showed no additional distinctive clinical manifestation. In contrast to high frequency of POLE1 mutations in ovarian endometrioid carcinoma, no POLE1 mutations were identified in patients with other subtypes of ovarian carcinoma. Our results showed for the first time that the POLE1 p.S297F mutation, but not p.P286R and p.V411L hotspot mutations observed in other cancer types, was frequent in Chinese ovarian endometrioid carcinoma, but absent in other subtypes of ovarian carcinoma. These results implicated that POLE1 p.S297F mutation might be actively involved in the pathogenesis of ovarian endometrioid carcinoma, but might not be actively

Full Text Available Iranians have come to Austria for a multitude of stated reasons. Within this paper the two authors follow their Iranian migrant interviewees' reasoning with two very different styles of analysis, each steaming from a particular scientific background. While Sociologist FLIEGENSCHNEE emphasizes schematic groupings with reference to push and pull factors, for Cultural Anthropologist CZARNOWSKI the interwovenness/interaction of these factors is more important. Together both develop a specific methodology of how to approach interview analysis with regard to migratory decision-making. URN: urn:nbn:de:0114-fqs090396

Background: Hand Eczema (HE) is a dermatological disorder with frequent relapses and multiple causes such as atopic, allergic and irritant contact dermatitis. The management is complex because of the wide range of different pathogenesis. Efficacy of some of available treatments is not well established and it can affect patients’ quality of life significantly. Methods: Reports on HE such as diagnosis, pathophysiology, pharmacological and nonpharmacological therapy that described in medieval Iranian medicine, were gathered and analyzed from selected medical and pharmaceutical textbooks of Iranian Traditional Medicine (ITM). The search of databases such as PubMed, EMBASE/Excerpta Medica, Science direct, Scopus, Google scholar, Web of science, Sid, Iran medex, Irandoc, was performed to reconfirm the efficacy of ITM remedies in conventional medicine from 1980-Jan-1 to 2015-Dec-30. Results: According to their opinion, HE is highly associated with liver function. This disorder was categorized into two main types as wet and dry ones. Most Iranian textbook explained signs of HE, as excessive skin itching, redness, burning and dryness. Treatments recommended by Iranian scientists were lifestyle modification, dietary intervention and performing the rules of prevention as well as herbal therapy and special manipulations. Conclusion: Iranian practitioners believed that, six essential principles, diet therapy and medicinal plants have high impact on treatment of HE. These remedies based on Iranian scholar’s experiences might be useful for further studies to the management of HE. PMID:27928524

Full Text Available Vermicomposting of organic waste has an important part to play in an integrated waste management strategy. In this study, the possibility of heavy metals accumulation with two groups of Iranian and Australian earthworms in sewage sludge vermicompost was investigated. Eisenia fetida was the species of earthworms used in the vermicomposting process. The bioaccumulation of Cr, Cd, Pb, Cu, and Zn as heavy metals by Iranian and Australian earthworms was studied. The results indicated that heavy metals concentration decreased with increasing vermicomposting time. Comparison of the two groups of earthworms showed that the Iranian earthworms consumed higher quantities of micronutrients such as Cu and Zn comparing with the Australian earthworms, while the bioaccumulation of non-essential elements such as Cr, Cd, and Pb by the Australian group was higher. The significant decrease in heavy metal concentrations in the final vermicompost indicated the capability of both Iranian and Australian E.fetida species in accumulating heavy metals in their body tissues.

As the Farsi-speaking Iranian population continues to grow in the United States, examination of their cognitive performance is an imperative first step to providing this group with culturally competent services. Thirty-six healthy primarily Farsi-speaking Iranian adults completed Farsi-translated and adapted versions of three frequently used measures of executive/subcortical functioning: Wisconsin Card Sorting Test (WCST), Trail Making Test (TMT), and Color Trails Test (CTT). Participants' performance on each measure was compared to published normative data resulting in 0-85% of cognitively and medically healthy individuals being classified as impaired depending on the executive/subcortical test score examined, with the highest impairment rates for specific WCST outcome scores. These findings raise questions for the use of published norms with Farsi-speaking Iranians residing in the US. The present study provided normative data from this group of Farsi-speaking Iranians on the Farsi-translated and adapted versions of the WCST, TMT, and CTT.

Refractory temporal lobe epilepsy due to spontaneous temporal pole encephalocele is a rare but increasingly recognized condition. Optimal surgical management is complicated by the lack of knowledge regarding both the extent of the epileptogenic area and the need for repair of the encephalocele. We report two cases that add significant information to these issues. In Case 1, with a 5-year history of refractory seizures, implantation of diagnostic subdural electrodes into the anterior temporal base happened to abolish the seizures completely. No structural changes were evident on postoperative magnetic resonance imaging. In Case 2, with a large encephalocele and a 5-year history of refractory seizures, surgical disconnection of the temporal pole successfully abolished seizures without any need for encephalocele repair. These two cases support the view that the epileptogenic area is confined to within the temporal pole for spontaneous temporal pole encephalocele. Temporopolar disconnection represents one surgical option for this entity that achieves seizure cessation without requiring extra repair procedures. Copyright © 2015 Elsevier Inc.

Full Text Available Derived from the emerging paradigm shift in English language teaching and assessment, there has been a renewal of interest in dynamic assessment (DA to be used as an alternative to the traditional static testing in language classrooms. However, to date, DA practice has been mostly limited to clinical treatments of children with learning disabilities, and it has not been widely incorporated into the EFL contexts. In order to find out the reasons behind the slow trend of DA practice, this research adopted a framework, based on the post method pedagogical principles and recommendations, to delve into the prospect of methodological realization of DA approaches in Iranian EFL classrooms. To this end, two instruments, a questionnaire and an interview were developed to explore the practicality of DA through seeking 51 Iranian EFL teachers' perception of DA practice in their classrooms. The results indicated that most of the teachers were negative about the practice of DA in their classrooms and believed that a full-fledged implementation of DA in Iranian EFL classrooms is too demanding. The feasibility of DA in Iranian EFL classrooms, where teachers are deprived of DA training, guideline, and technological resources, is questioned seriously due to the factors such as time-constrained nature of DA procedures, large number of students in EFL classrooms, the common practice of static tests as the mainstream, and overreliance on the teachers' teaching and assessment abilities. The paper suggests the framework of inquiry in this study, which was derived from the post method pedagogy, to be utilized as a blueprint for a critical appraisal of any alternative method or theory which is introduced into ELT contexts.

Cyber meets nuclear - Stuxnet and the cyberattacks on Iranian centrifuges

Energy Technology Data Exchange (ETDEWEB)

Englert, Matthias [IANUS, TU Darmstadt (Germany)

2013-07-01

In 2010 the computer worm Stuxnet attacked the information hardware of the Iranian uranium enrichment program. Stuxnet spread by USB flash drives and attacked SCADA software installed on Windows systems via several zero-day exploits. SCADA configures programmable logic controllers which control in the case of the Iranian centrifuge cascades frequency converter drives to choose the frequency of centrifuge motors. Thus the attackers were able to either change the rotation frequency of the rotor and thereby the separative power of the centrifuge or even destroy the fast spinning centrifuges by stopping and restarting them. The designers of Stuxnet must have had intimate knowledge of the facility design as e.g. the cascade connection scheme was programmed into Stuxnet. Based on this information some calculations of the Iranian cascade regarding the potential to produce highly enriched uranium will be presented using cascade simulation tools. The use of such highly sophisticated computer attacks to sabotage a nuclear program shed a new light on the debate about cyber attacks and the use of information technology for kinetic attacks in general. The talk will address problems the weaponization of information technology poses for international security and will highlight some more recent developments.

The Cuban Sandhill Crane Grus canadensis nesiotes and Cuban Parrot Amazona leucocephala palmarum are considered endangered species in Cuba and the Isla de la Juventud (formerly Isla de Pinos). Coincident with a public education campaign, a population survey for these species was conducted in the northern part of the Isla de la Juventud on 17 December 1995, from 06hoo to 10hoo. Residents from throughout the island participated, manning 98 stations, with 1-4 observers per station. Parrots were observed at 60 (61.2%) of the stations with a total of 1320, maximum (without correction for duplicate observations), and 1100, minimum (corrected), individuals counted. Sandhill cranes were sighted at 38 (38.8%) of the stations, with a total of 115 individuals. Cranes and parrots co-occurred at 20 (20.4%) of the stations.

The purpose of this study is to analyse Iranian scientific publications in the neuroscience subfields by librarians and neuroscientists, using Science Citation Index Expanded (SCIE) via Web of Science data over the period, 2002-2008. Data were retrieved from the SCIE. Data were collected from the 'subject area' of the database and classified by neuroscience experts into 14 subfields. To identify the citation patterns, we applied the 'impact factor' and the 'number of publication'. Data were also analysed using HISTCITE, Excel 2007 and SPSS. Seven hundred and thirty-four papers have been published by Iranian between 2002 and 2008. Findings showed a growing trend of neuroscience papers in the last 3 years with most papers (264) classified in the neuropharmacology subfield. There were fewer papers in neurohistory, psychopharmacology and artificial intelligence. International contributions of authors were mostly in the neurology subfield, and 'Collaboration Coefficient' for the neuroscience subfields in Iran was 0.686 which is acceptable. Most international collaboration between Iranians and developed countries was from USA. Eighty-seven percent of the published papers were in journals with the impact factor between 0 and 4; 25% of papers were published by the researchers affiliated to Tehran University of Medical Sciences. Progress of neuroscience in Iran is mostly seen in the neuropharmacology and the neurology subfields. Other subfields should also be considered as a research priority by health policymakers. As this study was carried out by the collaboration of librarians and neuroscientists, it has been proved valuable for both librarians and policymakers. This study may be encouraging for librarians from other developing countries. © 2012 The authors. Health Information and Libraries Journal © 2012 Health Libraries Group.
