The field of frustrated magnetism has been enriched significantly by the discovery of various kagome lattice compounds. These materials exhibit a great variety of macroscopic behaviours ranging from magnetic orders to quantum spin liquids. Using large-scale exact diagonalization, we construct the phase diagram of the $S=1/2$ $J_1$-$J_2$ kagome Heisenberg model with $z$-axis Dzyaloshinskii-Moriya interaction $D_z$. We show that this model can systematically account for many of the experimentally observed phases. Small $J_2$ and $D_z$ can stabilize respectively a gapped and a gapless spin liquid. When $J_2$ or $D_z$ is substantial, the ground state develops a $\mathbf{Q}=0$, $120^\textrm{o}$ antiferromagnetic order. The critical strengths for inducing magnetic transition are $D^c_z \sim 0.1\, J_1$ at $J_2=0$, and $J^c_2\sim 0.4\, J_1$ at $D_z=0$. The previously reported values of $D_z$ and $J_2$ for herbertsmithite [ZnCu$_3$(OH)$_6$Cl$_2$] place the compound in close proximity to a quantum critical point.


Abstract Fluid flow through a two-dimensional fracture network has been simulated using a discrete fracture model. The computed field-scale permeabilities were then compared to those obtained using an equivalent continuum approach in which the permeability of each grid block is first obtained by performing fine-scale simulations of flow through the fracture network within that region. In the equivalent continuum simulations, different grid-sizes were used, corresponding to N by N grids with N = 10, 40, 100 and 400. The field-scale permeabilities found from the equivalent continuum simulations were generally within 10% of the values found from the discrete fracture simulations. The discrepancies between the two approaches seemed to be randomly related to the grid size, as no convergence was observed as N increased. An interesting finding was that the equivalent continuum approach gave accurate results in cases where the grid block size was clearly smaller than the 'representative elementary volume'.


Critical inquiries into Arab American literary studies have often questioned the relative absence of this community from the ethnic canon, with feminist writers like Joanna Kadi describing Arab Americans as "the Most Invisible of the Invisibles" (xix). Such a statement situates this community vis-a-vis other ethnic groups in terms of a discourse of invisibility that, although varying between one group and another, still acts as a common ethnic marker. The isolated enclaves that ethnic groups in the US occupy, however, separate them not only from a hegemonic center, but more importantly from each other. This essay shows the ways in which author Diana Abu-Jaber contributes in her second novel, Crescent (2003), to the inclusion of works by and about Arab Americans in the ethnic studies category, suggesting ways to bridge the barriers separating Arab Americans from other ethnic minorities. Proceeding with an overview of Arab Americans' position in the US, followed by a discussion of borderlands in ethnic studies, this essay will then shift to an analysis of Crescent, carving out in the process a space for Arab American literature in what I will refer to as the ethnic borderland: a constructive space in which interethnic ties between and within different communities of color could be established and maintained.


In the years 2012–2019 observations were made of entomofauna found in the cultivars of purple coneflower [Echinacea purpurea (L.) Moench], lovage (Levisticum officinale W.D.J. Koch), garden angelica (Angelica archangelica L.) and chinese rhubarb (Rheum palmatum L.). The insects from the order of the Coleoptera beetles were the most numerous group. Beetles clearly dominated the cultivation of R. palmatum, where they constituted 87.6% of all insects caught, and the phytophages – flea beetles from Chaetocnema genus and Gastrophysa viridula (De Geer) turned out to be the most common species. In addition, during the harvest in 2016, severe damage to the roots of L. officinale by larvae of a previously unspecified species was noted. In 2018, the first wilting of lovage plants during vegetation was noted, and root infestation during the harvest period reached 100%. Barber's traps set up in 2019 confirmed that the species responsible for the losses is Liophloeus tessulatus (O.F. Müller).

Introduction: Cancer symptom management is essential in home caregiving. However, many family caregivers lack confidence and are ill-prepared to assist their loved ones in managing cancer symptoms at home. This lack of confidence or self-efficacy and preparedness among informal caregivers is heightened during early days of hospital discharge because of limited discharge preparation, and that many patients return home while still convalescing from treatment effects. Method(s): Based on Bandura's self-efficacy framework, we hypothesized that an individualized, tailored approach to training has the potential to promote self-efficacy and preparedness among caregivers. The specific aims of this study were to examine the effects of an individualized and tailored symptom management training on self-efficacy and preparedness in symptom management and home care of informal caregivers, and on symptom distress of cancer patients. The setting was 9100 at the Duke Hospital. The sample consisted of 120 dyads equally assigned in the treatment and comparison-control groups. Caregiver and patient data were collected before and after training, and at 1, 2, and 4 weeks of hospital discharge. Results: Analysis of caregiver data in the treatment group revealed that there was a significant improvement in self-efficacy in home care and symptom management immediately after training (t = -7.24, p<.0001) and was sustained at 1, 2, and 4 weeks of hospital discharge (t = -5.31, p<.0001; t = -4.81, p <.0001, and t = -4.45, p<.0001 respectively). This effect was not observed in the comparison-control group. Similar trend was observed in the levels of caregiving preparedness. The correlation between self-efficacy and preparedness was at 0.88. Further analysis is being conducted to look at patient data and to determine relationships between caregiver and patient variables. Discussion & Conclusions: This study could have important implications for the nursing community on how to effectively prepare family cancer caregivers for home caregiving. The findings of this research have potential for practical application and development of useful strategies for nursing interventions that offer both caregiver and patient support at the key moment of hospital discharge.

When I arrived at the National Institutes of Health (NIH) as a young research physician in 1978, I found a college-like campus of mostly red brick buildings. Children played among its trees, and nuns sang vespers in an adjoining convent. Change came, of course. Over the years, the campus sprouted sleek, modern laboratories that displaced many of the trees. The nuns left, their convent having been sold to the NIH for offices. However, nothing changed the campus like 9/11 and the anthrax attack that began just a week later. The open campus became an armed fortress. After all, what could be a more inviting target for bioterrorists than a huge government biomedical research complex? It was an anxious time. Experts raised the specter of terrorists obtaining variola (smallpox) virus from one of the two laboratories where it was known to remain (in Novosibirsk, Russia, and at the Centers for Disease Control and Prevention [CDC] in Atlanta, Georgia) and releasing it at a mass gathering (1). The federal research portfolio shifted, with extraordinary resources diverted to biodefense research and prevention over the next decade, and the number of biosafety level (BSL)-3 and BSL-4 laboratories grew rapidly nationwide (2). Laboratories with the BSL-3 designation permit work on organisms that can cause serious or potentially lethal disease if inhaled; BSL-4 laboratories, the highest containment designation, are for deadly organisms for which there are no effective treatments or vaccines. In the United States, there are now about 1400 BSL-3 laboratories (compared with about 400 a decade ago) and 14 operational or planned BSL-4 laboratories (up from 2 in 1990) (2). We now know that, despite efforts to protect us from the effects of bioterrorism as well as naturally occurring infectious diseases, we face another grave bioterror threat: the risk for disease and death emanating from biocontainment laboratories themselves. In 2008, investigations into allegations that a long-time researcher at the United States Army Medical Research Institute of Infectious Diseases in Frederick, Maryland, might have perpetrated the 2001 anthrax attack revealed security and safety flaws in that laboratory. This event should have been a serious wake-up call to examine our biocontainment laboratory security and safety, but the focus was more on the alleged crime than on the laboratory itself. A report issued by the U.S. Government Accountability Office the following year (2) raised serious concerns about the proliferation of BSL-3 and BSL-4 laboratories as well as safety lapses at those facilities, but its policy impact has been negligible. The director of the CDC, Dr. Thomas Frieden, recently revealed that, in June 2014, CDC laboratory workers improperly handled and stored what turned out to be live anthrax and that earlier in the year, the deadly H5N1 (bird flu) influenza virus was inadvertently mixed with a far more benign influenza strain in a CDC laboratory and then shipped to an outside laboratory (3). Senior CDC officials were notified of that event only after the revelation of the anthrax accident. We have now learned that vials of smallpox virus labeled 1954 have been sitting for decades in a U.S. Food and Drug Administration laboratory in a red brick building at the heart of the NIH campus (4)truly the stuff of science fiction movies. Despite the efforts aimed at keeping bioterrorists off the NIH campus, terror had existed within the fortress itself. How did the CDC lapses occur, and how could the vials have remained hidden at the NIH campus for nearly a lifetime? Human error, lax or nonexistent policies, poor inventory control, and administrative deficiencies seem to have been in play (5). Dr. Frieden has closed the CDC anthrax and influenza laboratories and halted transport of infectious pathogens in and out of CDC BSL-3 and BSL-4 laboratories until further notice (3). These steps are appropriate, as is, in my view, abandoning the naive belief that smallpox virus is stored in only 2 places in the world. But we also need a shift in our conception and conduct of biodefense research itself. In the aftermath of 9/11, we acted more from emotion than reason. Biodefense became an easy term to attach to all sorts of research grants to qualify for new large funding streams. Work with deadly pathogens suddenly became attractive to investigators who had no prior experience in this area. Building BSL-4 laboratories promised status and extraordinary long-term grant support for universities, which may have made them less than objective about the suitability of their campuses for such research. A BSL-4 laboratory was built at the University of Texas Medical Branch at Galveston, in an island city historically ravaged by hurricanes and protected only by a seawall. At Boston University, where I am an infectious diseases physician and professor of medicine, a BSL-4 laboratory that was finished in 2008 has yet to open because of a fierce, decade-long legal challenge by its neighbors, who fear a laboratory attack or an accident in their congested, largely minority community. All legal challenges have been exhausted, and this laboratory is now only one public health body approval away from opening (6). Dr. Frieden said of the CDC accidents that these events revealed totally unacceptable behavior. This is certainly true. Emerging reports suggest that the lapses are so great in number and risk as to strain credulity (5). They painfully illustrate that safely conducting research with deadly pathogens requires continuously updated laboratory safety training, policies, and procedures at least as much as bioidentity scanning, air filtration systems, space suits, and surveillance cameras. An all-encompassing culture of safety is essential, and that is what seems to have been missing at the CDC. I know from sad personal experience that research laboratories can be lethal places in which to work. In the 1950s, my father, a physicist, was exposed to asbestos while doing solar energy research in a government laboratory. He and his colleagues wore no protective clothes or masks while asbestos fibers that they believed to be harmless rained down on them. He died 2 decades later of mesothelioma at age 55 years, by which time the dangers of asbestos as a deadly carcinogen were well-known. The risks in BSL-4 laboratories today are exponentially greater than those in my father's laboratory long ago. They are immediate and extend not just to the laboratory workers and their families but also to surrounding communitiesand, in the case of smallpox and genetically altered H5N1 influenza virus, the entire globe. It is time to move past the fear created by the events of September 2001. We should suspend all research at BSL-4 laboratories until a thorough review of the CDC accidents can be completed. For the future, greatly limiting the number of BSL-3 and BSL-4 laboratories would probably better enable us to ensure their safety. We must contain the terror within.


Popular deep learning frameworks like PyTorch utilize GPUs heavily for training, and suffer from out-of-memory (OOM) problems if memory is not managed properly. In this paper, we propose a modification that utilizes CUDA Unified Memory (UM) to expand GPU memory to the available host memory space so that practicality for the programmer can increase, and OOM memory errors will not result for any workload. We also pinpoint performance issues that result from our modifications to the framework, and outline future plans like reducing redundant memory copies, prefetching, and memory advising techniques to improve upon our design. Our implementation shows that PyTorch UM performance overheads are minimal when the data footprint is below GPU memory capacity.


The measurement of scattering or diffusion properties can be performed in an anechoic, ideally freefield-like environment with a microphone array to capture the angle-dependent reflection directivity of the object under test. While this provides a complete set of data, the evaluation of the scattering or diffusing properties and the comparison with other similar objects is then carried out based on the energy-related scattering or diffusion coefficients. This is a standardized and fairly easy method but it results in a significant loss of detail from the original measurement data. This paper proposes an approach based on the Spherical Harmonics (SH) domain. Transforming the measured reflection directivity into a set of SH coefficients offers the possibility to analyze the reflection directivity in more detail. Most of all, this can be used to perform an order analysis to investigate the effect of the spatial discretization on the evaluation of the energy parameters. The outcome of this investigation will give an insight to the necessary array geometry for a future in-situ measurement method. The reflection directivity of several scattering and diffusing geometries will be simulated using the Boundary-Element-Method in order to obtain noise-free responses. The results will be evaluated with respect to the effect of spatial discretization using the SH decomposition. For different maximum sampling orders the established energy-related parameters will be calculated and discussed.


According to many political analysts fear has become an integral part of the present day political processes. The dynamics of nowadays development and the flow of negative information which pervades society require that scientists, devoted to their studies, spend adequate time for making their scientific results popular, for fighting against pseudo-science, for explaining the regional and global problems which our society faces today. The present-day era is totally different from the previous stages of humankind history. The main characteristic features of the present day are at least four: the dynamic development of science and technologies, the existence of weapons of mass destruction, the horrifying environmental pollution and growth in population. All these characteristic features of the present have a global character. In the time of globalization people should unite because they have a common destiny on Earth – the co-existence or non-existence. Global problems require global responsibilities. It is scientists who should be among the first to form new horizons for humankind

SUMMARY The tissue copper concentrations of Black Najdi sheep at the Hofuf Agricultural Research Centre (HARC) are reported. Lambs suffering from a delayed neonatal ataxia had low concentrations of copper in blood, liver and kidney, consistent with a diagnosis of copper deficiency, which was supported by histological examination of their brains and spinal cords. Low concentrations of copper and high concentrations of molybdenum and sulphate in forages produced at the HARC appear to contribute to the high incidence of neonatal ataxia observed there. The parenteral administration of 40 mg of copper to pregnant ewes improved the viability and weight increases of lambs over lambs born to untreated control ewes, even though all lambs had received an injection of 20 mg of copper soon after birth. The provision of supplementary barley to the lambs running with their mothers and with access to lucerne hay increased their growth and blood copper concentrations over animals restricted to the hay diet. The blood copper, haemoglobin and packed cell volumes of lambs born to ewes maintained on Rhodes grass were significantly lower than lambs born to ewes given lucerne, all ewes having received copper during pregnancy. This effect was attributed to the low copper and high molybdenum and sulphate content of Rhodes grass (Chloris gayana).


Terrorism and terrorists' tactics pose a tremendous threat to security on a global scale. This impacts the security of both developed and developing countries. A particular aspect of terrorist activities that increases the capabilities, and thus the threat, of terrorist organizations is the formation of transnational terrorist networks. These networks provide increased operability, mobility, and technology flow. This presents a particular challenge regarding the moral standards for the use of military force and standard measures to counter security threats. Just war theory is the framework that guides the ethical use of military force. The theory is broken down into three categories: jus ad bellum presents ethical guidelines for undertaking military action, jus in iv bello defines ethical standards for actions during armed conflict, and jus post bellum outlines responsibilities following the conflict. Current strategies, embraced by many global players, call for multilateral efforts with benefits spread across the globe. These strategies are based on building partner capacity and preventing escalation to kinetic military action. Additionally, these strategies are likely to prevent conflicts and reduce the ability of terrorist groups to operate effectively. Reducing conflicts shifts the strain on the ethical framework from evaluating military action to the ethical evaluation of who should help whom and when. Although the operation and organization of the networks challenge aspects of just war theory, it is indeed still viable. It is still relevant. More than ever, strong ethical values are needed to preserve the current world order and prevent the deterioration of humanity. Indeed, society must constantly remind itself that the values of preserving human life and dignity must be the overarching constants that guide all endeavors.


As one of the main disasters,drought affects development of economy and society in our country.With global climate change,increasing population,economic development and social progress,drought disasters present an expanding trend,and the influencing areas have changed,from traditional agriculture to industry,city and zoology etc.,from a deficient-water-zone to an abundant-water-zone,so the loss caused by drought is more and more serious.Drought severity monitoring and quantificational analysis are extremely intricate and systemic projects,involved many sciences and monitoring factors,so this paper introduced and researched on drought classification,indexes selection,index values establishment and main computation methods,by roundly collecting the main drought research and applying production of the United States and our departments,such as water resources,meteorology and agriculture.Then some thoughts and suggestions were presented with the status quo and demands in our country.


ARTICLE

Sir, We read with great interest the report of a Tunisian family by Rouzier et al . (2011) describing the neurological disorder linked to a novel heterozygous missense mutation in MFN2 (1p36.2) (Rouzier et al ., 2011). MFN2 mutations typically cause autosomal dominant axonal Charcot–Marie–Tooth disease (CMT2A, OMIM 609260), with peripheral nerve degeneration occasionally associated with visual failure and optic atrophy (Zuchner et al ., 2004, 2006). Interestingly, the clinical manifestations among mutational carriers in this Tunisian family were even more variable, ranging from asymptomatic subclinical disease to an axonal sensorimotor neuropathy complicated by optic atrophy, deafness, cerebellar ataxia and proximal myopathy. Furthermore, the intriguing finding of cytochrome c oxidase (COX)-deficient fibres and multiple mitochondrial DNA deletions in skeletal muscle biopsies suggest that MFN2 mutations can result in disturbed mitochondrial DNA maintenance and an overt respiratory chain defect, in addition to marked fragmentation of the mitochondrial network. These deleterious consequences are strikingly reminiscent of the pathological features recently highlighted in Brain for autosomal dominant optic atrophy due to OPA1 mutations (Amati-Bonneau et al ., 2008; Hudson et al ., 2008; Yu-Wai-Man et al ., 2010 a ). Here, we provide additional evidence that MFN2 …


In the early 20th century,under the leadership of four major tutors,Tsing-Hua National Literature Research Institute integrated Chinese and Western academy and educational ideas,studied China's inherent culture and cultivated a number of famous scholars in academic community.It had played an important role in studying and spreading China's traditional culture.Some of its traditions such as devoting much attention to the innovation of traditional culture,laying equal stress on both academic study and moral cultivation,etc.are still of great value and practical significance to us.


This paper is concerned with the centrality of aspect seeing in Wittgenstein's philosophy, with some analogies between religious beliefs and aspect seeing, and with the implications of these analogies for the question of the justification of religious beliefs. If belief in God is neither a hypothesis nor a regular perceptual belief but rather a type of aspect seeing, then the kinds of proofs and justifications that are applicable to it would have to engage the non-believer in a manner that would help her experience the dawning of a new aspect. This is why the standard philosophical proofs for theism, even when accepted as valid, are likely to be unsuccessful in bringing about faith.


We have developed a computer software program that analyzes the reproducibility of corneal topography systems. Using a Macintosh computer with Microsoft QuickBasic programming we created a program that records and analyzes the corneal power of 72,000 points per topography map (200 points over each one degree meridian) by linear interpolation of the Placido-based ring data. Reproducibility studies on 7 normal and 7 abnormal (pathological and postsurgical) corneas were performed with 2 Placido ring based topography systems with EyeSys Corneal Analysis System and the Humphrey MasterView system. Five exams were performed by two technicians each. The mean, range and standard deviation of corneal power was calculated for all points on a map, and represented pictorially for each patient. Statistical analysis of standard deviation at each point was used in assessing the reproducibility between systems and between technicians. The topographic maps of mean power range and standard deviation are presented for selected patients. The overall mean standard deviation of power and the means within concentric annular zones and quadrants are presented for each system and technician for both normal and abnormal cornea. Intraobserver variability of each system were not significantly different for both normal and abnormal corneas. There was no significant difference between technicians, nor were there regional differences in variability.standard deviation of power is presented for each system and technician comparing intersystem and intraobserver variability for both normal and abnormal corneas. A precise method of analyzing multiple variation of reproducibility in corneal topography is now available through a new proprietary software system.


AC Splendor is a hard red spring wheat that meets the end-use quality and kernel visual distinguishability specifications of the Canada Western Red Spring class. AC Splendor was evaluated in the Central Bread Wheat Cooperative Registration Test in 1993, 1994 and 1995 and was found to be adapted to the wheat-growing regions of the Canadian prairies. In comparison to the check cultivars Neepawa, Katepwa, Columbus, Roblin and AC Majestic, AC Splendor grain yield was similar to Katepwa, Columbus and Roblin; however, AC Splendor exhibited earlier maturity by 2.8, 7.5 and 1.6 d, respectively. AC Splendor is resistant to Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. E. Henn. that causes the disease stem rust and P. triticina Eriks. that causes leaf rust and has intermediate resistance to Tilletia tritici (Bjerk.) R. Wolff and T. laevis Kuhn in Rabenh. that causes common bunt. Resistance to Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schwein.) Petch] that causes fusarium head blight is poor. E...


A "double standard" in the sense that both gold and silver were used as money. Some countries were on the gold standard, some on the silver standard, some on both. Both gold and silver were used as international means of payment and the exchange rates among currencies were determined by either their gold or silver contents. Gresham's Law implied that it would be the least valuable metal that would tend to circulate.


Reinforced endotracheal tubes (ETTs) are regularly applied in anesthetic practices to prevent compression or kinking. Although these tubes are designed to bend easily and prevent obstruction, they still carry a potential hazard of being obstructed following external forces. In this article, we reported an unusual case in which a reinforced ETT was collapsed due to the patient bite. The patient ' s bite force on the tube resulted in obstruction, hypoxia, and desaturation. To overcome this near-fatally condition, we removed the blocked reinforced ETT.


Motivated by the needs of online optimization of real world engineering systems, we study the single sample path based algorithms for Markov decision problems (MDPs). We give a simple example to explain the advantages of the sample path based approach over the traditional computation based approach: matrix inversion is not required; some transition probabilities do not have to be known; it may save storage space; and it gives the flexibility of iterating the actions for a subset of the state space in each iteration. The effect of the estimation errors and the convergence property of the sample path based approach are studied. Finally, we propose a "fast" algorithm which updates the policy whenever the system reaches a particular set of states; the algorithm converges to the true optimal policy with probability one under some conditions.


The present paper considers the issues of mutual neutralization and toxicity elimination of toxic components of industrial by-products as well as the study of strength formation for sulfur-containing woodcrete composites exposed to various permanently acting loads and curing conditions in time. Woodcrete-concrete composites could be considered as one of the available lightweight heat insulating building materials with low heat conductivity and good sound proofing properties. The materials are based on recyclable raw materials widely available in the regions of Kazakhstan and Russia. The contemporary provisions of theory and practice of development of efficient lightweight woodcrete-concrete on the base of composite sulfur-containing binders obtained by the method of toxicity elimination and mechanochemical activation served as the methodological foundation of the research. While implementing scientific research, the authors used the standard measuring instrumentation and methods of analysis of physical and mechanical properties of woodcrete composites such as the up-to-date methods of X-ray diffraction analysis, differential thermal and microscopic analyses and testing equipment. The principle of mutual neutralization of toxic components of industrial by-products by means of mechanochemical treatment at low temperature has been applied in the paper. These methods allow reducing cement content due to its fractional replacement by industrial waste. For the experimental part of the research, ferrous iron with the oxidation number 3 (Fe2O3) has been used as the oxidizing agent, while elemental sulfur, wood coal dust and ferrous iron with the oxidation number 2 (FeO) have demonstrated regeneration properties. The properties of sulfur-containing woodcrete specimens have been studied after 7, 28 and 90 days of exposure in various curing conditions. It was stated that sulfur-containing woodcrete had been fractioned gradually, first, decomposition of mortar constituent part took place, then of organic filler fibers. The obtained results could be applied while manufacturing efficient walling material for civil engineering buildings and structures, including seismic areas.

Forward error correction (FEC) with high coding gain is needed to achieve PR30 (29 dB) link budget in 50G-PON. In particular, the stringent capacity and latency requirements of the 50G PON call for innovations in the design of FEC codes to go against the noise in the channel. In this paper, we propose a generic FPGA design for an adaptive irregular LDPC coding emulator that supports hard-decision, soft-decision, shortening, and puncturing. We evaluate the error-correction performance of the low-density parity-check (LDPC) forward-error correction (FEC) code that is currently under study by ITU-T's 50G-PON group for burst-mode upstream reception. Through experimental measurements based on a real-time FGPA platform, we found that soft-decision (SD) offers ∼1.3 dB more gross coding gain than hard-decision (HD). The SD LDPC performance is well maintained for non-uniform input bit error distributions where the errors are concentrated at the first 1/8 of each code word, corresponding to ∼44 ns (∼88 ns) for a 50-Gb/s (25-Gb/s) upstream signals. This indicates the suitability of the use of the SD-LDPC for burst-mode upstream reception in 50G-PON.


I compare macroeconomic performance, measured by the volatility of real GDP and inflation, for two of the countries that opted not to enter the EMU: the United Kingdom and Sweden. In particular, I am interested in finding out how much of the macroeconomic performance changes experienced by the U.K. and Sweden after 1999 is due to increased efficiency in the conduct of independent monetary policy. Eventually, the objective is to analyze whether or not further changes in macroeconomic volatility could have been attained if these two countries would have instead adopted the Euro starting January 1999.


Thirty Wistar albino rats of both sex, 1-1.25 months old (average body weight 250 – 300gm) were used. Animals were randomly divided into three groups. 1 st group (acute group) n=10 given 0.5 ml. contain 500 mg/kg/body weight NaF, as single toxic dose via stomach tube. 2 nd group (chronic group) n=10 given 0.5 ml. contain 150 mg/kg/body weight NaF via stomach tube daily for 60 days. 3 rd group (control group) n=10 given 0.5 ml. physiological saline via stomach tube. Clinical signs were reported during the course of the study, and then sacrificed after 3 and 7 days in 1 st group, and 30 and 60 days in 2 nd group, then post mortem examination was done, and any gross lesions were reported. Blood collected was done for biochemical examination (T3, T4, and TSH.) using special biochemical kits. Pieces of thyroid were taken, fixed in 10% formalin for 72 hours, and then all the specimens were processed and the histopathological changes were observed under light microscope.

In this dissertation, the mathematical model of effect of manufacturing errors including microstructure relative height error and relative width error on diffraction efficiency for the harmonic diffractive optical elements (HDEs) is set up. According to the expression of the phase delay and diffraction efficiency of the HDEs, the expression of diffraction efficiency of refraction and diffractive optical element with the microstructure height and periodic width errors in fabrication process is presented in this paper. Furthermore, the effect of manufacturing errors on diffraction efficiency for the harmonic diffractive optical elements is studied, and diffraction efficiency change is analyzed as the relative microstructure height-error in the same and in the opposite sign as well as relative width-error in the same and in the opposite sign. Example including infrared wavelength with materials GE has been discussed in this paper. Two kinds of manufacturing errors applied in 3.7~4.3um middle infrared and 8.7-11.5um far infrared optical system which results in diffraction efficiency and PIDE of HDEs are studied. The analysis results can be used for manufacturing error control in micro-structure height and periodic width. Results can be used for HDEs processing.


Medical diagnostics help us evaluate a range of disorders, such as cancer and infectious diseases. In the United States and other developed countries, doctors have access to advanced equipment and laboratories that provide reliable diagnoses. As a result, when we are sick, we feel confident that we will get the treatment we need. Unfortunately, for many developing countries around the world, these kinds of resources do not exist. The Program for Appropriate Technology in Health (PATH)--an international nonprofit that designs health technologies such as vaccines and diagnostics specifically for developing countries--is one organization working to change this imbalance. As a medical diagnostics scientist at PATH, Bernhard Weigl develops inexpensive, portable, user-friendly diagnostics that provide fast and reliable test results. His tools help communities with minimal health care resources get proper care and treatment. Work overview. Medical diagnostics scientists research new and improved ways to diagnose human diseases. My focus is in-vitro diagnostics, which means I develop new methods to measure the presence or concentration of a chemical or biological species--sometimes called a diagnostic marker or biomarker--in a sample (e.g., in blood, saliva, stool, urine, or tissue). A biomarker, for example, may reveal a pathogen in a patient, which implies the presence of an infectious disease. A high or low concentration of a biomarker may point to problems with liver function, a developing cancer, or an impending heart attack. In general, scientists in this field try to find new biomarkers for diseases that are currently difficult to diagnose, increase the sensitivity of a diagnostic to allow earlier detection, or make a diagnostic method easier to use or less expensive. Point-of-care diagnostics. As the director of PATH's Center for Point-of-Care Diagnostics for Global Health, I lead a group of 25 scientists, engineers, business people, and administrators. Because of my role, I spend a lot of time attending meetings, writing grant applications, giving presentations, and teaching at a university (I am also a professor). Although most of my time is spent outside the lab, I am still involved in science and discovery through developing new research, planning innovative projects, and working with colleagues to review and troubleshoot experiments. My group develops sensitive, easy-to-use, low-cost diagnostic methods for diseases that are particularly relevant in developing countries (also called low-resource settings). We design new methods to diagnose long-standing diseases, such as nucleic acid assays for tuberculosis and bacteria-causing diarrhea. We also use existing methods to create additional tests for emerging diseases, such as immunoassay test strips for human immunodeficiency virus (HIV) and malaria. In addition to developing diagnostic devices, we work with companies and government labs to manufacture these tests and distribute them (at low cost) to users in developing countries. So far, we have worked mostly with manufacturers in the United States, Europe, and India. …

L18: The authors should mean something different, because a ROS event consists of rain and snowfall. Answer: I use the "precipitation event" instead of "ROS event", the ROS event include rainfall, snowfall and sleet. p. 4138, L20: not proper English. Answer: done p. 4138, L23: "generated by air temperature". Air temperature itself won't generate melt, but sensible and latent heat do (for example). Answer: "generated by sensible heat and latent heat" instead of "generated by air temperature". p. 4138, L26: "avalanche" -> please write "avalanche formation" Answer: done p. 4140, L3: "it was not used regularly as a snowpack characteristic": I think the cited references show otherwise. Answer: "It was not used regularly as a snowpack parameter" instead of "it was not used regularly as a snowpack characteristic". p. 4140, L18: "Snow in this region". I guess it is meant here: "New snow in this region...". Answer: "Snow in this region" is correct. p. 4140, L25: "estimated" is not a correct word for this sentence and the sentence is not so clear. I guess the authors meant something like: "Thus, one day in this study was defined from 20:00 LT to 20:00 LT in the next day." However, the authors should think about this sentence too, because it leaves some ambiguity, as it is not so clear if the 20:00LT measurement from this day, or the next day is used. Answer: In this study, one day was defined from 18:00 LT (GMT+6) to 18:00 LT ((GMT+6)) in the next day, 18:00 (GMT+6) LT was regarded as the end of one day (when calculated the temperature and energy balance, 18:00 was classified into the current day). p. 4141, L14, Eq. 2: Is this accuracy (like: -1.2142857) of the coefficients in the equation justified? Please only report only the number of digits that can be justified. Answer: The equation is provided by instruction of Snow Fork gauge. I check the equation in this paper, all number are correct. p. 4141, L24: "estimated" is not a correct word for this sentence. Please write: "The


The economic growth of a country is directly linked to the growth of several sectors, in which the construction sector is prominent. The objective was to investigate by means of ergonomic analysis the external coating activity performed on building façades, due to its high degree of difficulty. The methodological approach was composed by a review of the literature and quantitative research using the OCRA checklist method, highlighting the biomechanical overload risk analysis of the external coating activity in mortar based on International Standard ISO 11228-3: 2009.

Tendency of earnings management practice approaching merger and acquisition aims to increase share price before stock merger so that it can reduce company purchase cost of acquisition target. Previous research has proven the presence of profit management. While, company size is considered having ability to affect on company value. Since larger size or scale of company will lead to easier company way to obtain sources of funds both intern and extern. This research aims to describe the effects of earnings management on the disclosure of stock return and effects of company size on stock return. Population in this research is acquisition companies that are registered in Indonesia Stock Exchange in 2011-2016. Sampling technique used purposive sampling so there are 40 companies as the research samples. The data used in this research are secondary data taken from ISE website and TICMI. Analysis technique is multiple linear regression, the regression model also has passed classical assumption test. Results of the research indicate that acquisition company management truly conducts earnings management when publication before acquisition announcement. The earnings management by acquisition companies give negative effects on stock return; meanwhile company size has no effects on stock return of acquisition companies.

2-Hydroxy-4,6-dimethoxyacetophenone (4) was glycosylated with O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl) trichloroacetimidate (5) and trimethylsilyl triflate as promoter to yield directly the C-glycoside 6. Construction of the flavone system by application of a Baker-Venkataraman-type rearrangement followed by deprotection yielded isoembigenin (2). Glycosylation of 4,6-bis(tert-butyldimethylsilyloxy)-2-hydroxyacetophenone (17) with the trichloroacetimidate 5 afforded the O-glycoside intermediate 18 which was converted via Fries rearrangement into the C-glycoside 21. Applying again the Baker-Venkataraman rearrangement and cyclization gave isovitexin and vitexin derivatives 25 and 26, which were completely deprotected to yield isovitexin (1b) and vitexin (1a), respectively.


Objective
To search for the metabolites that associated with articular cartilage damage in the urine of rat model with articular cartilage destruction induced by T-2 toxin.

Methods
Thirty healthy male Wistar rats aged 4-5 weeks were numbered by weight, randomly divided into two groups (n= 15 per group), namely the control group and the model group. The rats in the control group were fed with standard rat diets, and those in the model group were given diets contaminated by T-2-toxin (300 μg/kg). Throughout the experiment, all animals were given free access to distilled water and diets. After continuous treatment for 3 months, all the rats were sacrificed. The changes of articular cartilage in rat knee joints were observed by histopathological method, the metabolic profile of rats' urine was determined by ultra performance liquid chromatography/quadrupole time of flight-mass spectrometry (UPLC/QTOF-MS) technique. Combined with multivariate statistical analysis, database searching was applied to explore and confirm the different metabolites associated with cartilage damage.

Results
Light microscope showed that rats' articular chondrocytes in the control group presented cells in neat rows and eumorphism, rats' articular chondrocytes in the model group presented extensive areas of chondrocyte degeneration, necrosis and loss. In rats' urine metabolic profiles, 5 different metabolites associated with cartilage destruction were detected, such as 4-hydroxynonenal (HNE), trans-4,5-epoxy-2(E)-decenal (EDE), 5-methyldeoxycytidine, and 5-L-glutamyl-glycine and prolyl-valine. Compared with the control group (mass spectrum peak area: 65 820 ± 5 200, 22 080 ± 3 538, 4 292 ± 3 520, 3 277 ± 2 025, 1 104 ± 990), all of them increased in the model group (mass spectrum peak area: 90 240 ± 18 863, 25 610 ± 5 071, 9 702 ± 6 562, 6 029 ± 3 905, 4 144 ± 5 322, t=-3.903, -2.209, -2.814, -2.424, -2.174, all P < 0.05).

Conclusions
The articular cartilage destruction induced by T-2 toxin could cause the changes of related metabolites in the urine; the 5 kinds of changed metabolites in urine are related to articular cartilage destruction.

Key words:
T-2 toxin; Articular cartilage; Injury; Metabonomics


Value capture is a practice that uses the public potential value of road infrastructure involving private sector contributions. It is of increasing interest to developing countries. The value-capture approach can help the local government to manage problems in infrastructure provision following weak capacity, limited budget, and lack of innovation. Value capture is about capturing a part of the increment value from the private property following the benefits of related public infrastructure (road, bridge, open space, etc). It aims to return the benefit for public use. The thesis assumes that, in Indonesia, value capture can support the local government in terms of capacity improvement and new institutions, particularly in financing or providing infrastructure from using local resources involving the private sector. Considering that value capturing for infrastructures is relatively new, institutional support is needed for its implementation. There tends to be a lack of public sector capacity and impeding bureaucracy, as well as a need to improve cooperation with the private sector to deliver infrastructure. A responsive design of institutions that adjusts to local conditions could help facilitate cooperation between public and private sector as well as to speed up the infrastructure delivery to the public. Responsive institutional design should be based on local context and local institutional capacity. Responsive institutions are also significant for managing the process of value capturing, which involves a complex set of three stages: creating value; unlocking value; and capturing value. The dissertation shows that each stage has a different process. A fitting "5WH framework" is presented regarding cooperation between public and private sector (who), selecting potential arrangements fitting local conditions (how), encouraging private sector to contribute in-kind or financially (what), assessing the increase benefit and impacts of investment at micro and macro scale (where), and setting the timing of capturing the value (when). A key finding is that value capture is encouraged by the public sector in Indonesia; however, cultural or socioeconomic factors influence the motivation in the private sector to participate. The Indonesian cases show different characteristics of regions responding to the idea of value capturing. In the Kartamantul regions cultural factors such as gotong-royong and guyub are significant in encouraging private sector involvement and contribution. In Bekasi district, value capturing is driven by socioeconomic factors -the private sector voluntarily built a connector road at the Jakarta – Cikampek toll road to capture significant profit from infrastructure investment. These different cases have influenced the design proposal in this dissertation for a responsive institutional design. Clearly, the shape and format of institutions need to accommodate local culture and socioeconomic conditions. Responsive institutional design requires governmental system improvements and facilitates actors' capacities for value capture implementation. The study proposes a local public service agency (Badan Layanan Umum Daerah or BLUD) and a joint cooperation agency for Indonesian urban planning and infrastructure development practice. The BLUD should be considered particularly fitting for the Kartamantul case, particularly for arranging cooperation with the private sector on investment, development, and maintenance. For the Bekasi case the study underlines the importance of developing a joint cooperation agency, which is an independent institution to arrange voluntary cooperation with the private sector. It is suggested that the formats of a local public service agency and a joint cooperation agency are a good fit to local conditions and context, and therefore offer an essential step in to further supporting the implementation of value capturing in Indonesia.


Development of various morphologies such as beads, beaded fibers, and pure fibers, and their potential application for humidity sensor by electrospinning of polymer/composites was described. In order to produce uniform nanofibers with high reproducibility, a controlled current electrospinning system was utilized. It was found that the solution concentration plays a significant role in bead/fiber formation. Furthermore, it can be observed that fiber diameter of beaded‐fiber was smaller than pure fiber. It is hopes that by controlling morphology of composites fiber, the optimal condition for obtaining the high performance humidity sensor could be attained.


During the eighties, Latin America was surrounded by economic crises, increased external debt, and poor growth of the Gross Domestic Product as well as little attraction of foreign direct investment (FDI). Later in the nineties, some countries in the region inspired by the desire to eliminate the protectionist model had to undertake reforms that sought to achieve their commercial opening to start a new economic model and thereby show the world as an attractive area for attracting investment mainly from Europe and Asia. One of the countries that made institutional changes by creating good conditions in the nineties as well as in the next decade to attract FDI was Colombia. The purpose of this paper is to demonstrate how Colombia attracted foreign capitals during 2005-2012. A probit model was applied (Botello, J.&Davila, M.,2015) to determine if the probability of improving the number of determinants to attract FDI will result in more inflows. The results show that the design of an industrial policy focused on attracting FDI, as well as the increase of the Gross Domestic Product, the offer of natural resources to foreign investors, the skilled workforce and the improvements in infrastructure were the determinants that increased the attraction of capitals. The implications for policy makers are to improve the rest of the determinants studied in this original research to increase the FDI flows into Colombia. Corresponding author: Juan Carlos Botello Email address for corresponding author: email@example.com First submission received: 5th June 2018 Revised submission received: 5th November 2018 Accepted: 24th November 2018 Introduction In recent years, FDI has grown faster than trade flows and global production for various reasons such as political and economic changes in many developing countries. Those changes are characterized by the shift to democratic political systems as well as changes toward economic and legal systems oriented in the direction of trade liberalization in which Colombia and other countries played an important role since 1951 when signed as a GATT member. Many developing countries have made economic and structural changes in order to obtain some benefits and attract FDI, in that sense, FDI flows are likely to be attracted to developing economies that pursue an outward-oriented strategy of economic development such as Colombia (IMF, 2015). In Latin America, the relative stability of the region and the adoption of outward-oriented public policies have reassured foreign and local investors based on market reforms. Because of such liberalization and changes, the FDI increased in developing countries in the 1990 ́s (Erdal, F. & Tatoglu, F., 2002) and particularly, Latin America has shown a sustainable growth since 2010 (ECLAC, 2013). International Journal of Business and Economic Development, Vol. 6 Number 3 November 2018 www.ijbed.org A Journal of the Academy of Business and Retail Management (ABRM) 2 On the other hand, the attractiveness of a state or a city for foreign direct investment flows depends on the number and kind of determinants they possess. Deichmann, J., Karidis, S. &Sayek, S. (2003) found that some factors determining the spatial decisions of multinational firms in a Middle East country depend on policy implications. Considering the above, the government agenda should focus on making the country more attractive for FDI, especially in times of crisis when traditional determinants are put to the test and inspire proposals for new opportunities. Popovici, C. & Calin, A. (2012) note that the idea of entering a new era of determinants of FDI is not new as there are several studies that highlight the key factors for attracting FDI. This emphasizes that the classical theories of FDI probably should be changed and others should be based on the emergence of new local capacities. This research is divided as follows. In second part, a literature review is offered. Several research papers were analyzed to describe the key factors for attracting FDI considering classical theories in order to compare them with the determinants used by Mexico (Botello et al., 2015).Section three includes the data and variables used to explain the new determinant creation theory; based on the model proposed by Botello, et al. (2015) where the most relevant determinants used to obtain FDI are infrastructure, skilled labor, low labor cost, security, tax-break, natural resources, gross domestic product, legal system, geographical location and industrial policy. A probit model to test the theory in section four is presented. Finally, conclusions are discussed in section five. Literature review Latin America has undergone great economic changes. In 1982, the external debt crisis that affected the entire region exploded. Moreno, N. (2008) reported that this, generated capital flight and negative growth, which made that decade was considered "lost."At the same time, the economic policy of President Deng Xiao Ping helped make Latin America look very attractive to capitals from Asia, which allowed the arrival of volumes of investment, production and trade as well as the opening of multinational companies (Moreno, N., 2008). These were the beginnings of the flows of foreign investment in the region that originated the economic change that contributed to the stabilization of the crisis. After these events, positive changes began in the region; several contributions of Foreign Direct Investment (FDI) were made in the years 2005 to 2012. This contributed to a good and constant economic growth, since better investment flows were achieved like never before.FDI, in addition to be an opportunity for economic growth for each country, also means that it is one of the best and most effective ways to internationalize the region and make it a participant in globalization (Zapata, Y.; Kalmanovitz, S., 2007). Latin America, in general, has seen economic stability from 2005 to 2012 (which is the period studied in this article), with steady annual growth that indicates that each year the government strategies work best for attract new companies to these territories (ECLAC, 2005) but in recent years FDI in the region continued trending downwards. In 2017, FDI flows into the region stood at US$ 161.911 billion, 3.6% down on 2016. The main two reasons for the decline have been lower export commodity prices— which have led to a substantial drop in investments in the extractive industries— and the economic recession in 2015 and 2016, mainly in Brazil, albeit also in other South American economies. These two trends, however, were partially reversed in 2017, as commodity prices recovered and the region returned to growth (1.3%). Most of the literature related to the attraction of FDI by countries is based on different theories such as localization economies and their determinants, trade and resource endowments. In that sense, the eclectic paradigm of Dunning (1988) argues that the path FDI takes is partly due to the specific advantages which one country has, because of its regional geographic location and / or location in the world. These advantages arise from using resource endowments and / or assets held abroad by some countries in the world which are attractive to a company by combining them with its own resources. International Journal of Business and Economic Development, Vol. 6 Number 3 November 2018 www.ijbed.org A Journal of the Academy of Business and Retail Management (ABRM) 3 That combination suggests that if a foreign company wants to use the resources of a country, it should establish a subsidiary by initiating a flow of FDI and then establish a start-up operating facility (Hill, Ch., 2008) but, the risk is a main determinant that has to be considered. As of 2010, countries that wanted to invest in Latin America began to take an interest in the technology sector, but due to the low level of the industry, they took advantage of the opportunity to invest in low and medium-low technology (ECLAC, 2010).One of the sectors in which Latin America has been a recipient of investment from Europe is electricity, focused on the telecommunications, banking and energy subsectors (Zapata, Y., 2007). On the other hand, one of the main reasons why the European Union decided to invest in Latin America is the opportunity that this region offers to access new and distant markets. Within the contribution of the Colombian legal framework as an incentive to attract FDI, there is a whole process to remove the protectionist model that historically had, this process began in 1990. It wanted to propose an opening of international competition, beginning by adapting neoliberal tendencies, efficient allocation of resources and institutional changes begun in the government of former President Virgilio Barco and at the beginning of the mandate of César Gaviria, with whom they became official and put into practice. These new policies were based on principles such as economic freedom, foreign trade reforms, labor legislation, foreign exchange regime, foreign investment policies, among others (Ramirez, C., 2011). During the 2000s, the prohibition of FDI was eliminated in sectors that were previously not allowed and new financial, tax, labor, and port provisions were implemented in a positive manner, as well as an international investment statute. The law that stands out most is Law 963, made in 2005, under which investors will continue to be entitled to facilities and accessibility for them, under certain specifications imposed by the government (Ramirez, C., 2011). The elimination of infrastructure gaps plays a key role in sustaining strong and broad-based growth and supporting further economic diversification. Relatively weak road infrastructure represents an important obstacle not only for overall GDP growth, including through export diversification, but also for achieving a more evenly-distributed economic performance across regions in Colombia.

Social science books, and especially edited volumes, should be judged primarily by the criterion of how well they fulfil their expressed ambitions. By this measure Race and Ethnicity in the 21 Century, whose central objectives are to provide an intellectual and informational resource for students of ethnicity and race and a platform for expert scholars to reflect on important subjects springing from these broad themes, must be judged a success. Each of its chapters contributes to the editors' goal of bridging a set of accessible essays that address important issues pertaining to ethnicity and race in contemporary Britain and, to a lesser extent, in other advanced industrial societies. Organized into eight chapters and a substantive introduction and conclusion, the book surveys several public policy fields, notably housing (Malcolm Harrison and Deborah Phillips), asylum settlement policy (Patricia Hynes and Rosemary Sales), policing (Eugene McLaughlin), health provision (James Y. Nazroo) and education (David Gilborn and Nicola Rollock), and covers two venues, labour markets (Satnam Virdee) and the mass media (Myria Georgiou), where issues of ethnicity, race and immigration intersect daily. The final chapter (Anthony Heath, Catherine Rothin and Sundas Ali) assesses the degree to which ethnic minorities identify as British and the depth of prejudice towards ethnic minority populations within the predominantly white majority population. The essays reach the following major conclusions respectively: racism remains a crucial variable in determining the housing and general settlement patterns of ethnic minorities (Chapter 2); the British government's policy of dispersing asylum seekers has contributed to their social marginalization and undermined overall social cohesion (Chapter 3); the location of ethnic minorities in domestic labour markets reflects the interactions between the changing political opportunity structure of 1980s England and the emergence of an effective anti-racist social movement (Chapter 4); operational policing in a post-Macpherson Report and post-September 11th environment is conflicted between the objectives of enhancing community cohesion and safeguarding national security (Chapter 5); variable health outcomes among ethnic groups can be traced to the wider social inequalities which plague these groups (Chapter 6); government education policies are implicated in outcomes that sustain racial inequities (Chapter 7); the persistent under-representation of ethnic minorities in media production and often unflattering media coverage of immigrants and ethnic minorities undermine minority-majority group social relations (Chapter 8); and, although general popular opinion towards immigration and ethnic minorities remains illiberal to a significant degree, ethnic minorities nevertheless report a high level of attachment to Britain and only a minority are alienated from British society (Chapter 9). To what extent do the aforementioned findings expand our understanding of the dynamics of ethnicity and race in Britain and beyond? In responding to this question three things can be said. First, despite the considerable breadth and depth of its subjects the volume is framed and its essays are predominantly informed by a sociological and social policy perspective. This is a problem only in that at least two of its chapters (3, 4) are obviously inspired by a macro viewpoint that implicitly claims, but does not necessarily demonstrate, a sophisticated understanding of British and/or European politics. Moreover, given that the editors explicitly Ethnic and Racial Studies Vol. 34 No. 1 January 2011 pp. 162 181


The paper describes research needs in primary R&D areas for the family of dual-coolant lead-lithium (DCLL) blankets. Associated key scaling parameters are introduced and evaluated under conditions of FNSF, ITER and DEMO and also for the existing non-fusion MHD facilities, using the MaPLE loop at UCLA as an example. Comparisons among these parameters are recommended for measuring the R&D progress on the pathway from the present experimental facilities to FNSF. Possible experiments both in the existing facilities and FNSF are discussed along with the flow diagnostics.


The lectin from Dictyophora indusiata Fisch was isolated and purified by physiological saline extraction, (NH 4) 2SO 4 precipitation and Sephadex G-75, Sepharose 4B chromatography. It turned out to be a single band on PAGE. SDS-PAGE showed that it contained one subunit, whose molecular mass was 53?000.This lectin agglutinated rabbit erythrocytes and human erythrocytes, it also agglutinated the peripheral lymphocytes cells and S 180 tumor cells from mouse. The hemagglutination of the lectin on rabbit erythrocytes was inhibited by lactose and L-fucose among the sugar tested. Amino acid composition analysis showed that it contained 15 kinds of amino acid, in which the content of aspartic acid and valine was relatively high.

Dihydro-1,3,2H-benzoxazine dimer derivatives or dihydro-benzoxazine dimers are a class of compounds typically prepared by ring-opening reactions between dihydro-benzoxazines and phenols. Dihydro-benzoxazine dimers act as chelating agents for several transition and rare-earth cations. To better understand the chelating properties, it is necessary to examine their structural features and electrochemical characteristics thoroughly. However, the electrochemical properties of dihydro-benzoxazine dimers have not been tremendously examined. Herein, eight derivatives of dihydro-benzoxazine dimers possessing different substituents on the benzene ring and the tertiary-amine nitrogen were synthesized as model compounds to investigate their influences on crystal structures and electrochemical properties. The crystal structure of the dihydro-benzoxazine dimer, namely 2,2′-(cyclohexylazanediyl)bis(methylene)bis(4-methoxyphenol) (7), is identified for the first time and further used to compare with the crystal structures of other derivatives reported previously. For all the derivatives, intermolecular O–H⋅⋅⋅O hydrogen bonds are the significant interactions to hold the crystal packing of (7) and also the other derivatives. Hirshfeld surface analyses confirm the presence of intermolecular O–H⋅⋅⋅O hydrogen bonds. Redox behavior of the eight dihydro-benzoxazine dimers was studied by cyclic voltammetry. An oxidation peak observed at 0.25–0.47 V corresponds to the oxidation of the phenolic –OH group to the phenoxonium intermediate. The shift in the electrochemical peak positions is due to the different abilities of the substituents to stabilize the phenoxonium cation intermediate. The stabilizing power is ranged in the following order: methoxy > dimethyl > ethyl ≈ methyl, and N-cyclohexyl > N-methyl. Thus, the derivative (7), which contains both the methoxy and N-cyclohexyl groups, has the lowest oxidation potential. Our work elucidates the effect of the substituents on the crystal structures and electrochemical properties of the dihydro-benzoxazine dimers.

Republican stalwart newspaper The Adams Sentinel ran nothing in its folds hinting at the editor's elation over the Emancipation Proclamation in the days following the document's release. In a terse column, headed, "Proclamation of the President," ran the document, unadorned with either accolades or contempt. Elsewhere in the paper's folds, the news hovered back and forth over the fields around Sharpsburg and word of the lackadaisical pursuit of Lee's army into Virginia. The deep meaning of one of Lincoln's most momentous moments seemed to be lost on the Republicans of south-central Pennsylvania, as they eschewed the topic, pussyfooted around it and went out of their way to nearly ignore the document which sat in Washington City with its ink still drying.


Aim: Assessment of early results of the pulmonary artery valve transvascular implantation (PAVTI). Methods: Study group consisted of 4 patients (3 women), aged 27-31 years, with pulmonary homograft dysfunction (stenosis in all patients and concomitant pulmonary regurgitation in two of them). The reasons for homograft implantation were total repair of tetralogy of Fallot (2 patients) and Ross procedure due to congenital aortic valve stenosis (2 patients). Qualification to PAVTI was based on clinical evaluation, echocardiographic studies and assessment of morphological and functional features of right ventricle and homograft with the use of cardiac magnetic resonance Artyku3 oryginalny/Original paper


The early literature on rent seeking presumed that total expenditures in the rent-seeking process would equal the value of a contested prize. Subsequent analysis has shown, however, that a number of circumstances give rise to underdissipation of the contested rent-imperfectly discriminating contests, risk-aversion, or where individuals' valuations of the prize are not identical. This paper shows how underdissipation is associated with the public-good character of contested rents. In particular, total rent dissipation is demonstrated to be less than the average stake of the individual contenders. In addition to assessing rent dissipation in contests for public-good allocations, the paper also endogenizes the value of the prize by placing the rent-seeking contest in a setting of candidate competition.

In 1900, Manchester cotton-textile manufacturers invited their continental rivals to tour Lancashire. In this period, British hours of work were twenty per cent below continental levels, putting Lancashire firms – it was believed – at a competitive disadvantage. The Mancunians' objective was to demonstrate to Europeans the superior organization of Lancashire's factories and its social and moral benefits. If all went according to plan, Europeans would consider reducing working hours. The British plan backfired. Upon visiting Lancashire, foreign competitors discovered a higher proportion of women and children at work than in Europe. They would agree to a shorter work day if the British restricted the labor supply of women and children and hired more men in their place. The proposition was of course rejected. The belief that international integration posed a threat to national labor standards was widespread one hundred years ago as it is today. Capital and labor in developed countries had a shared concern about the uneven playing field – although they proposed dramatically different solutions. Employers used the threat of market loss to promote lower national standards, but labor gave strong backing to international agreements that would raise working conditions on the continent and abroad to the highest established levels. When multilateral arrangements failed, labor sought to attach 'social clauses' to bilateral trade agreements. Caught between the opposing views of labor and capital, certain governments adopted a policy of isolationism. Predating by a century Freeman's (1995) comment about the ineluctable link between local working conditions and global trade, Bismarck (cited in Fallows 1951, p. 91) observed bluntly: "A normal workday could be established for Germany alone, if Germany were surrounded by a Chinese wall and were economically selfsufficient."

Abstract : When unidirectionally solidified at rates below 3 cm/hr, the Ni3Al (gamma')-Ni3Cb (delta) alloy grew with the eutectic phases as alternating lamellae aligned parallel to the direction of solidification. The lamellar phase morphology was examined by transmission electron microscopy, and the planes were found to exhibit preferred growth directions, (110) gamma' and (100) delta parallel to the direction of solidification. The interfacial planes most commonly observed were (-111) gamma' parallel to (010) delta. The tensile properties of the eutectic were evaluated in the temperature range of 75 to 2200F and the creep and rupture properties in the temperature range of 1600 to 2200F. Its high temperature tensile and creep properties, measured in the direction of alignment, were found to be superior to all nickel base superalloys. The dynamic elastic modulus of the eutectic and its thermal expansion were measured from 75 to 1800F. The modulus was higher and the expansion lower than that which is typical for nickel base superalloys. Other properties of the eutectic which are reported include its notched tensile strength, the effect of interlamellar spacing on the strength, the temperature dependence of its impact properties, microhardnesses of the eutectic phases, compressive properties at room temperature, and oxidation behavior.

Magnetic domain wall velocities are compared for (Eu,Lu)3 (Fe,Al)5O12 films grown on (110) and (111) Gd3Ga5O12 substrates. The (110) films have an orthorhombic anisotropy which is partly stress induced and partly growth induced; the (111) films are uniaxial. Wall velocities approaching 500 m/sec have been measured in the orthorhombic films while the (111) films exhibit a maximum velocity of ∼5 m/sec. The results are compared with theoretical limiting velocities.


With fast deployment of wireless local area networks (WLANs), the ability of WLAN to support real time services with stringent quality of service (QoS) requirements has come into fore. In this paper, we evaluate the capability of QoS support in Enhanced Distributed Channel Access (EDCA) mechanism of the IEEE 802.11e standard, which is the medium access control (MAC) enhancements for QoS support in 802.11.EDCA mechanism allow prioritized medium access for applications with high QoS requirements by assigning different priorities to its four access categories. Its performance is evaluated under real time audio and video traffic through simulations using Network Simulator-2(NS 2), parameters like mean delay, throughput are calculated and graphs has been plotted. Simulation results show that EDCA mechanism provides satisfactory service differentiation among its four access categories. With EDCA mechanism, network capacity is effectively increased to better support real-time audio and video transmissions Index Terms— Quality of service, wireless local area networks, enhanced distributed channel access, access categories, 802.11


Abstract Strolling is a complex activity that requires the synchronization of the brain, anxiety, and muscles, as well as rhythmic movement of the lower limbs. Gait may be abnormal if coordination is disrupted. As a result, exoskeletons should be used to treat it effectively. The connection and other systems contained in the exoskeletons could be used to mimic the behavior of the human lower leg. These mechanisms are created utilizing complex traditional methods. This study proposes a new gait-inspired method based on a genetic algorithm (GA) for synthesizing a four-bar mechanism for exoskeletons. For each phase of the gait, the trajectory is calculated and merged using optimization algorithms. Each phase of the trajectory passes through 10 precision points, for an entirety of 20 precision points in 1 gait cycle. For the problem under consideration, it is discovered that the GA outperforms other literature techniques. Finally, the proposed design for a lower limb exoskeleton is depicted as a solid model. Furthermore, the generated link-age accurately tracks all the transition points, and the simulation of the planned linkage for one gait cycle has been illustrated using a stick diagram.


The purpose of this study is to explore the possibility of preserving scientific facts in the translation of the Qur'an, as one of its challenging and inimitable features. It should be pointed out that many scientific subject matters, dealt with in the Qur'an, give rise to translation challenges. Such matters are scientifically proven by today's scientific discoveries, but not dealt with sufficiently in translation. Lack of knowledge in many scientific issues results in incompatibility between the translation product and the advanced knowledge of today; this requires that translators of the Qur'an should be equipped with thorough scientific knowledge in order to enable the target text accommodate the source text's scientific facts. The theoretical part of the study is based on the idea that scientific facts in the Qur'an have not been adequately scrutinized from a translational perspective. Most of their efforts focus on the linguistic aspects and literal semantics of the sacred text, stripped from scientific implications. In order to prove the translators' unintended neglect of these facts, a number of translations are examined and enough supporting explanation of scientific resources is provided to show the congruence between what was revealed in the Qur'an before fourteen centuries, and what modern sciences have uncovered. The study draws the conclusion that scientific knowledge in different scientific fields is essential in the translation of the Qur'an, as it is a possible fact that the translator is liable to commit mistakes in the translation of scientific statements if s/he is not expert or specialist in the scientific discipline under question. Therefore, translators should be knowledgeable in all aspects of the Qur'an in order to be able to provide an authentic rendition in the receptive language.


In this study, we consider the sulfur dioxide emissions trading pilot scheme (SETPS) of China, with pilot provinces as the treatment group and other provinces as the control group. We employ the difference-in-differences method to estimate the effects of the SETPS on pollution mitigation and economic growth. Results show that the SETPS plays a robust role both in China's industrial sulfur dioxide abatement and in economic growth. Furthermore, by applying regression analysis to explore regional heterogeneity, we find that it has a stronger effect on industrial sulfur dioxide reduction in the Central China than it does in the Eastern and Western China, and it also exerts a positive influence on economic growth in the Western China. Moreover, a time-trend analysis indicates that the pollution reduction effect of the SETPS has decreased, while the economic growth effect has slightly increased since 2007.


In view of the potential fault risk in the field operation of the acquisition terminal, there is still no effective method to make a reasonable evaluation on its running state. In this paper, we pick up the important influence factors of terminal running state and divide them into four aspects by using the data record of MDS system, electricity information collection system and SG186 information system. Then the fuzzy theory and analytic hierarchy process are used to construct judgement matrix. At last, we establish the running state analysis model which can be accurate to evaluate the running state of the acquisition terminal. At the end of this paper, we use a concrete example to illustrate our assessment process and get good results. Using this method to analyze the operation state of the acquisition terminal can effectively monitor the operation state of the acquisition terminal, which is of great significance to the field operation and maintenance work.


The living environment monitoring is a critical issue today. Many related researches focused on developing the living environment monitoring systems by using the web-based technology, but such information systems would increase the difficulty of promotion and migration to others, because of needing well-trained engineers to achieve and maintain such information system. This research focuses on developing the weather monitoring system. The main goal of the research is to use the technology of message queuing telemetry transport (MQTT) as roles of the communication layer instead of direct-connecting database, which can isolate the system migration complexity from heterogeneous relational database management system (RDBMS) and construct a distributed information system easily. Finally the contributions are demonstrated as implementation of the IoT-based weather monitoring system. The prototyping of the weather monitoring system is implemented and deployed at Wu-Tso elementary school for the students' learning of nature science and activity environment. In addition, the system is implemented using open sources and is easy to be deployed and scalable.


Historically, luxury relies on new technologies but the connection between luxury and technology is not new. I will illustrate how ritual, wealth, science and technology are embodied in luxury. I will point to ancient archaeological and architectural treasures and will discuss how mining,
 advanced construction and soldering techniques and the transformation of bronze alloy, for example, represented an integration between the highest levels of taste, craftsmanship and scientific technology. Luxury is modernity and in antiquity we see it as a forward moving force at the highest
 levels of development. When we think of haute couture, there seems to be nothing in common with say, for example, Hipsters or Silicon Valley engineers. But when we think of technology as a common node, we find that concern with artistry, provenance, the importance of the maker, as well as
 science, are common denominators. Luxury impacts everyday life and answers to contemporary culture at large.


This paper uses an original data-set for 186 workplaces in Thessaly (central Greece), to study consequences of Greece's strict employment protection law (EPL) and national minimum wage for temporary employment. We find higher temporary work contract rates among workplaces that pay low wages close to the minimum. We also find that EPL 'matters', in particular, managers who prefer temporary contracts because temporary workers are less protected definitely employ more. Our findings thus support the view that a firm's HRM decisions regarding internal versus external allocation of tasks are influenced by labour regulation.


We show that when X = P 1 k , the projective line over the field k, with the open covering {X0 = Spec(k[x]), X1 = Spec(k[y])}, the Mayer-Vietoris sequence of the K-theory of the schemes with endomorphisms for the covering is not exact for all Ki when i = 2n+1 and n ≥ 1. This leads to the conclusion that the K-theory of schemes with endomorphisms is a global theory.


This paper describes a new algorithm that composes blues melodies to fit a given chord sequence. It comprises an analysis stage followed by a synthesis stage. The analysis stage produces a Markov model composed of zero, first‐, and second‐order transition tables covering both pitches and rhythms. In order to capture the relationship between harmony and melody, a set of transition tables is produced for each chord in the analyzed songs. The synthesis stage uses the output tables from analysis to generate new melodies; second‐order tables are used as much as possible, with fall back procedures to lower‐order tables. Some constraints are encoded in the form of rules to control the placement of rhythmic patterns within measures, pitch values for long duration notes and pitch values for the start of new phrases. The model was evaluated by a listening experiment; results showed that listeners were unable to reliably distinguish human from computer composed melodies.


Power supply and cable connection is difficult in the environment of high-temperature (HT), and the general electro-elements also out of gear. Therefore the measurement of temperature and pressure in HT is always a difficult problem. The new LGS crystal has well piezoelectric characteristics and temperature stability, which provides possibility for the HT applications of SAW sensors.In this paper, the HT and SAW properties of LGS are analyzed, and the methods and key questions about its application in HT wireless passive sensor are discussed. The feasibility about HT wireless passive SAW sensing system based on LGS has been verified by the initial experiment.


. The compressive and shear behavior of masonry is here studied both experimental-ly and numerically. An experimental campaign has been carried out on 9 square-shaped one leaf masonry panels, reproducing historical masonry. Tests have been done for evaluating the elastic and shear moduli in both plane directions, with 6 panels rotated by 90 degrees, leading to vertically aligned bed joints, and 3 panels maintained with horizontal bed joints. Compressive tests were executed on 6 masonry panels, 3 of them rotated by 90 degrees. Initial shear strength and shear modulus parallel to bed joints are evaluated through shear tests on 9 masonry triplets. Shear tests are performed on 3 rotated panels, applying an horizontal distributed load, without vertical compression. Attention is paid to the service load state: only the initial phase of the tests is studied. Numerical models are proposed for representing actu-al masonry behavior, both discrete [1] and continuous [2,3], standard and micropolar, obtained by homogenization procedures [4]. Several numerical analyses are performed for simulating the experimental tests on masonry triplets and panels. The mechanical elastic parameters
